Scams On The Elderly Can We Do Anything About It Essays - Fraud

Scams on the Elderly: Can we do anything about it? Scam artists have always preyed on the gullible, but in recent years, much of the focus of these thieves has been on the elderly. It is quite a well known fact that the elderly possess the greatest percentage of disposable income with the least amount of debt. Old people with money. Scam artists prey upon these people with unrelenting deception. It is not a problem that will just go away. The problem must be analyzed and only then can we learn what to do. First we must analyze the different "red flags" which identify certain members of the elderly as targets for scams. First off, these older consumers are often living alone, with no one else to watch their finances for them. Being alone, they are often very appreciative and receptive of guests, especially those who pay a visit even to sell them something which will be of benefit to them or their homes. They are also very receptive to anything promising assistance to their health conditions or home repair requirements. Scam artists also look at demographic numbers to choose their elderly targets. According to Jeanne Mackin, an author for a consumer watch organization, 80 % of people age 65 and over have at least one major health problem of some sort and spend a great deal of their monthly budget on health care. And combine that with the fact that 71% of those people own their own homes, of which many were built before 1950, and you have a combination ripe for fraud against the elderly. (1) Some examples of fraud against the elderly include: - A "city inspector" arrives at the home, stating he needs to check the plumbing, furnace, or wiring, and when problems are found, states that he will call a "friend" to make the repairs. The work is overcharged and done poorly, if at all. - The older consumer receives in the mail newspaper clippings about a new health miracle product with a "personal" handwritten note saying, "Try this! It works!" But when money is sent, the product never arrives, is overpriced, or is useless, if not just plain harmful. - A product demonstrator arrives at the home and asks the resident to sign a paper just saying that the demonstrator visited. In fact, the trusting consumer, who hasn't read the form, signs a contract ordering the product. (1) Telemarketing is another powerful tool scam artists use to prey upon the elderly. By being on the phone, the con is relying on his/her voice to convince the person that they are providing that elderly person a valuable service or product. They are good at taking advantage of people's honesty and politeness.(5) The con artist's favorite targets using the telephone, are those suffering with memory loss. By taking advantage of this, the con artists can call someone up and gather as much personal information as possible. A favorite scam is for the con artist to make that information gathering call, and then the next day, if the senior cannot remember the first conversation, the con then tells the senior that they "sent too much money", and that they need to send a new check for the "correct" amount. Either out of forgetfulness of the previous call, or out of sheer guilt, that elderly person writes the check for the amount requested. (2) Another very common method of scamming the elderly is sweepstakes mailers. or everyone, the chance to win thousands upon thousands of dollars, or to win major prizes is always a welcome thought. Especially to those who were not so fortunate to gather much money throughout their lives. Usually, the scam requires for the elderly person to send in a "confirmation deposit" on their prize, which is NEVER required of a winner in any legitimate contest. If the elderly person ever hears from the contest people, it is usually just to let them know that they have the opportunity to buy over-priced products and then receive a small, cheap gift, which was probably what they were promised as a prize to begin with.(4) Watch for signs of these gifts around the elderly person's house. (3) Consumer fraud costs all Americans billions each year, but it is the elderly which carry the lions share of the amount. These con artists not only cause financial ruin among the elderly, but also cause a great deal of emotional distress and even health problems as a result

Common Themes in Eveline and Good Country People essays

Common Themes in Eveline and Good Country People essays While some people seem to be exact opposites, we often find that they have more in common than what we realize at first glance. This is a lesson from which we could all learn because nothing is as it seems. Two stories that illustrate this fact through choices and stark realizations are Eveline by James Joyce and Good Country People by Flannery OConnor. Both stories illustrate the power of paralysis, the role of women, and missed opportunity through the characters of Eveline and Hulga. While these two women appear to be different on the surface, we learn the same life lessons through a series of their difficult circumstances. Eveline never quite realizes what has occurred to her because she refuses to delve into the future and its possibilities. Her lesson is left to us. On the other hand, Hulga is forced to face certain things about herself that she never considered before and we can learn from her experience along with her. Each women, though worlds apart, teaches us somet hing about human nature. While each of us is in our own place on the earth, we are not that different from one another. Eveline and Hulga are women that become paralyzed by circumstances. In Eveline, Eveline becomes paralyzed because of indecision. In short, she is torn between two choices. She desires a new life where people would treat her with respect (Joyce) and she would not be treated like her mother. She even knows that a new life with Frank was a ticket to freedom. We read, Frank would save her. He would give her life, perhaps love, too. However, she wanted to live. Why should she be unhappy? She had a right to happiness. Frank would take her in his arms, fold her in his arms. He would save her (Joyce). While these statements may be true, they are not enough to cause Eveline to leave her current situation. This is essential to understanding Evelines character becaus...

Financial Accounting Concepts Phase 4 DB Essay Example | Topics and Well Written Essays - 500 words

Financial Accounting Concepts Phase 4 DB - Essay Example In accordance with the introductory part of the report, it can well be stated that Management Information System (MIS) is a tool that assists management end users in decision making by providing/generating timely reports in a pre-defined, well documented fashion. From this definition, the key words that can be identified are: Thus implying that for routine decision making, managers are in need of some pre-defined reports that are generated by an MIS on a routine basis. Timely availability of required information is precisely what managers need today for effective decision making process. Thus, it can be well derived that MIS systems generate reports that also enhance the decision making ability of managers by means of providing quick and effective reports from the existing set of data and information. MSS or Management Support Systems were the earlier form of an MIS, where the prime target was to give information and support for the efficient decision making by managers. But the buzz word of MIS got clicked and became famous all over in the 60s. the concept of MIS, though older and much advance technologies have come into play these days, is still of much significance to organizations, mainly for the two reasons listed below: Its major emphasis is on the usage of IT by the business managers. As the true goal of a computerized IS is to support the decision making process of the management, not just data processing of the POS generated data. Its stress is towards the framework of systems that compiles and keeps organized set of IS applications. Business applications of IT should always be considered as unified and incorporated computer based information systems and not as autonomous data processing jobs. Providing information and support for management decision making by all types and levels of managers is a complex task. Such task is eased by the application of an MIS that eases the flow of

Management Practices in the Workplace Essay Example | Topics and Well Written Essays - 1250 words

Management Practices in the Workplace - Essay Example entrusted with five functions namely: planning, leading, organizing, staffing and controlling which must be done efficiently and effectively to achieve organizational success. These will be the subject of this paper especially their implementation in a practical situation. This is one of the critical functions of management. According to Block (2011 p. 16) is the capacity to initiate a future distinct from the past. This can only be achieved through practices that foster high employee engagement. DuBrin (2008) and Reilly et al (2011) view planning as a process of setting goals and deciding on how to achieve them. Organizations unlike in the past whereby they used to have crisis management whereby decisions are made when problems arise; make long-term plans to guide the future of the organization. The manager must develop a vision and mission for the organization to guide all its activities. Plans can be strategic, tactical or operational depending on their use. Strategic plans are long-term and determine the future of the business. They are developed by high levels of management and form the basis for lower level tactical and operational plans. Tactical plans are developed for functional areas of the organization or business unit in a global company. These tactical plans according to DuBrin (2008) are for implementation of strategic plans through division into specific goals. They are also formulated by middle level managers. Operational plans on the other hand, are concerned with specific procedures and actions involved in running day-to-day activities or daily performance targets (Reilly et al. 2011). However, tactical and operational plans should be aligned with strategic plan. The operation plans in this case ensure efficiency (doing things right) while strategic plans ensure effectiveness (doing the right things) (DuBrin, 2008, p. 135; Reilly et al. 2011). For exa mple at Tripac, the most important decisions such as increasing market share or to do with

Changing role of women in society Assignment Example | Topics and Well Written Essays - 1250 words

Changing role of women in society - Assignment Example Therefore, it is well noted that the role of women has changed a lot since the 1860s based on the efforts of the women with respect to economic, cultural and societal factors. To give an insight of the changing role of women in the society, the author of Little Women, Louisa May Alcott clearly represents the life of women during the 19th Century. It is from her assumptions that the gains, which women have achieved since 1860s can be well depicted. Based on the story composed by Alcott, the novel revolves around the conflicts that emerged between the domestic duties of the women and the need for them to have their own personal growth attributed to the various abilities they possessed. In the cases presented of the four sisters, the character Amy was faced with the challenge of being a dutiful woman and also a professional artist (Alcott 22). This certainly shows that the boundary that was set for the women in the society during the early 19th Century was surpassed. The role and the status of women have gradually changed since the efforts that were set up to change the attitudes that were labelled against them in the society. The most dramatic consequences that were brought about by the industrial revolution in the late 1800s have propelled many economic changes that address the role of women currently in the society (Begun 33). The industrial revolution sparked a lot of changes ever since its inception especially towards the aspects of work and salaries that the women were entitled to in their workplaces. The separation of the domestic duties of the women and their workplace paved ways for women to compete with men for job opportunities. Of course, this did not suit the liking of the men, but there was nothing they could do since times were changing. It is quite obvious that the role of women with regards to employment has faced a number of changes. Women are now entitled to employment

Electromagnetic Radiation Features

Electromagnetic Radiation Features 2.1 Electromagnetic radiation Electromagnetic radiation consists of waves of electric and magnetic energy oscillating through space at the speed of light (OET, 1999). The electromagnetic spectrum is an arrangement of various electromagnetic energy in the forms of particles and waves. These form of energy are characterized by frequency and wavelength. The wavelength is the distance per seconds covered by an electromagnetic wave, while the frequency, the number of oscillation of electromagnetic waves for one second. Figure 2.0.1 bellow shows an electromagnetic spectrum. Figure 2.0.1. Electromagnetic spectrum The electromagnetic spectrum shows the arrangement of electromagnetic sources based on their frequency and wavelength. Below is Table 2.0.1 which describes the radiofrequency sources and their allocated bands and frequency ranges. Table 2.0.1. Characteristics and frequency bands of radiofrequency field sources Band Description of signals Frequency range FM Frequency Modulation 88’108 TV/DAB Television (analogue) DAB (Digital Audio Broadcasting) 174’223 TETRA Terrestrial Trunked Radio 380’400 TV Television (analogue and digital) 470’830 GSM DL Global System for Mobile Communications from base station to mobile phone 925’960 DCS DL Digital Cellular System 1,805’1,880 UMTS DL Universal Mobile Telecommunications Service 2,110’2,170 Wi-Fi Wireless Fidelity, IEEE 802.11 standards 2,400’2,500 The most important application of electromagnetic energy is in the use of radio broadcasting, mobile telephony, microwave application and satellite communication as reported by Kelly (2011). Others include magnetic resonance imaging (MRI), Microwave ovens, radar, industrial heaters and sealing (Kelly, 2011). 2.2 Radio waves Radio-frequency (RF) is a part of the arrangement of electromagnetic energies in terms of their frequencies from 3 kilohertz (3 kHz) to 300 gigahertzes (300 GHz) (Kelly, 2011). Radio-transmitters are devices that serve as transducers for converting electrical current into electromagnetic waves. The knowledge of the presence of electromagnetic field was first discovered as far back as 1887 when a Physicist proved experimentally that electromagnetic fields can be produced and detected in space. This phenomenon was predicted three years earlier by Clarke Maxwell (1831-1879). A radio transmitter communicates with a receiver via radio waves when electric charges moves up and down the transmitters antenna and are detected when the electric charge oscillate up and down a receivers antenna. In the process, when the charges moves, they produce magnetic fields. The resulting changing electric-magnetic fields (electromagnetic waves) are able to travel long distances through an empty space (Vacu um). The ability of a transmitter to send signal to a receiver or another transmitter nearby depends on the oscillation of the charges up and down its antenna at a particular resonant frequency. 2.3 Characteristics of radiofrequency (RF) antenna There are a number of physical parameters and principles that define the type of wave and intensity of the radio waves generated and broadcasted into the environment. These parameters are relevant in understanding the behavior of the antennas. These are the antenna element, element array, gain or directivity, radiation pattern, radiation intensity, beam-width and power density. 2.3.1 Antenna Elements The antenna element is a basic unit of the antenna. They may exist as individuals or as a group of elements. There are three most common types: dipole, monopoles and loop. A dipole antenna is most commonly a linear metallic wire or rod with a feed point at the center. It has two symmetrical radiating arms. A monopole antenna on the other hand has a single radiating arm. A number of authors have performed calculation and measurements on the pattern generated by these field on mobile handset in air and also against the head (Jensen Rahmat-Samii, 1995) ; (Okoniewski Stuchly, 1996) and (Lazzi, 1998). Other works on wireless devices such as cellular telephones using monopole antenna has also being reported in literature (Luebbers, 1992). An interesting application of loops is the wireless telemetry for medical devices and used for the first pacemaker (Greatbatch Holmes, 1991). 2.3.2 Antenna Arrays To yield a highly directive patterns, multiple antennas or elements can be arranged in space, in various geometrical configurations to yield a pattern (Stutzman Thiele, 1998); (Bucci, Ella, Mazzarella, Panariello, 1994) ; (Balanis, 2005); (Elliott, 2003) and (Mailloux, 1994). This antenna configuration are called arrays. The field from an array can add constructively or destructively in others. When well-engineered, the array can be used to control the beam by changing the phase of the excited currents of the individual elements (Elliott, 2003) ; (Dolph, 1946) ; (Safaai-Jazi, 1994) and (Shpak Antoniou, 1992). By so doing, an optimum radiation beam can be generated. The geometry of the arrangement of the element also affects the performance. Other factors are distance between the elements, amplitude of the excited currents, phase excitation and radiation pattern. 2.3.3 Directivity and Gain Another parameter used to describe the directional properties of an antenna is the directivity or gain. The directivity of an antenna, is a figure of merit that quantifies the antenna directive properties by comparing them with those of a hypothetical isotropic antenna that radiates the same total power as the antenna being characterized. Antenna such as dipoles and loops generates omnidirectional pattern, (McDonald, 1978) and (Pozar, 1993) derived a formula for such. The gain of an antenna is a measure that takes into account the efficiency of the antenna as well as its directional capabilities. The total antenna efficiency accounts for losses at the input terminals and the structure of the antenna due to reflection, conduction and dielectric losses. 2.3.4 Radiation Pattern       Besides the parameters described above, the radiation pattern is the property used to describe the resulting shape of the beam generated. Radiation or an antenna pattern is a mathematical function of the antenna that describe the space coordinates (Balanis, 2005). The main beam is the region where the radiation is strongest and the other directions forms the side-lobes. The half-power beam width is the measure of the direction of maximum radiation. The beam width or Half-Power Beam width (HPBW) is the width of the power pattern at the location where the beam is 3 dB below its maximum value (half-power points) or the location where the field is 1/Ã… ¡2 of its peak. It is often used as a trade-off between it and the side lobe level (The ratio of the radiation intensity of the largest side-lobe to the maximum radiation intensity). The HPBW varies inversely as the side lobe level. The most common resolution criterion states that the resolution capability of an antenna to distinguish betw een two sources is equal to half the first-null beam width (FNBW/2), which is usually used to approximate the half-power beam width (HPBW) (Kraus, 1996) and (Kraus Marhefka, Antennas, 2002). 2.3.5 Polarization Furthermore, the generated wave can oscillate up and down, left and right or characteristic between these. These behavior describe the kind of polarization the wave exhibits. Polarization of a radiated wave is defined as that property of a wave in a time-varying direction and relative magnitude of the electric field vector. In general, however, when the shape of the electric field appears in the form of an ellipse, the polarization is described as elliptical. When the shape appear linear or circular, the polarization is described as such. The polarized radiated wave by the antenna can also be represented on the Poincares sphere (Balanis C. A., 1989) ; (Poincar ´e, 1892) ; (Deschamps, 1951) and (Bolinder, 1967). 2.3.6 Radiation Intensity Another important property of the antenna is the radiation intensity. The radiation intensity is the power radiated per unit solid angle subtended by the antenna. It is the property of the far field. The radiation intensity is obtained by multiplying the density by the square of the distance. The power pattern is also a measure of radiation intensity. To be able to obtain the total power density, one need to integrate the radiation intensity. 2.3.7 Power Density Finally, the radiation power density describes the power associated with an electromagnetic wave. The power density is the total power crossing a closed surface by integrating the normal component of the Poynting vector over the entire surface. 2.4 Electromagnetic field around an antenna An electromagnetic field is the region created around a source of electromagnetic radiation. An antenna is a device which changes electrical charges or current into electromagnetic waves into space. The distribution of RF energy from an antenna was found from literature to obey a directional pattern and varies with distance from the antenna. The fields created around an antenna can be grouped into two: 2.4.1 Near Field The near field is the region around an antenna such that; the electric and magnetic fields are decoupled, quasi-static and are not uniform. And the impedance which is the resistance in air and the power associated with the field varies with distance. 2.4.2 Far Field The far field on the other hand have plane fronts which do not depend on the shape of the source but rather unchanging. The radiated power decreases inversely with distance from the antenna theoretically. The electric and magnetic fields are uniquely defined by approximately a constant impedance of the medium. Figure 2.0.2 below illustrate the field regions around an antenna. Figure 2.0.2. Electromagnetic field regions around a typical antenna 2.5 Advances in field modeling A modeling is a good approximation of a problem to a real world solution. There are various mathematical modeling methods available in literature to date (Sarkar, Ji, Kim, Medouri, Salazar-Palma, 2003) ; (COST-231, 1999) and (Correia, 2001). Extensive theoretical and experimental research on electromagnetic field Levels has been carried out and reported in literature (Lin, 2002) ; (Cicchetti, 2004) and (Nicolas, Lautru, Jacquin, Wong, Wiart, 2001). Currently, the studies in electromagnetic fields can be grouped into two dominant channel modelling approaches: theoretical and empirical (Rappaport, 2002). While theoretical models depend on the knowledge of the physical laws of the wireless channel, such as the electrical properties of the ground, empirical models are based on actual radio frequency (RF) measurements of wireless channels. Furthermore, one can regroup it into Monte Carlo, Empirical and Physical models (Rappaport, 2002). Monte Carlo method are statistical in nature and m ake use of statistical and distribution functions such as channel characteristics of radio-transmitters and ray-optics. (Okumura, Ohmori, Kawano, Fukuda, 1968) Found out from measurement that for a situation where one cannot have a line of sight with the transmitter, the fading (attenuation) of the received voltage approximates relay distribution. Okumura also developed a correction factor to be used together with the data to correct for the field strength. When Okumuras measured results were averaged, the results showed properties of a lognormal distribution. (Okumura, Ohmori, Kawano, Fukuda, 1968) And (Mogensen, Eggers, Jensen, Andersen, 1991). The style of settlement and nature of buildings also affect the propagation of the radio waves when traveling from a source into the environment. Also random variation of building also contributed to loss of propagation of the waves. Some earlier work suggested that radio waves propagates over buildings and are diffracted down to street levels (Parsons, 1992). To be able to obtain reliable statistics, a lot more of measured data was required. Diffraction is when the path of the beam is obstructed by surface of irregular shape edges. Diffraction methods were developed and used to account for diffractions at rooftop (Ikegami, Yoshida, Takeuchi, Umehira, 1984). Variations in building height contributed to the shadow loss of propagation over low buildings. The most general approach uses numerical integration of physical optics integrals (Walfisch Bertoni, 1988) and (Bertoni, 2000). Measurement has shown that Monte Carlo methods need to consider the effect of trees (Mogensen, Eggers, Jensen, Andersen, 1991), (Rizk, Mawira, Wagen, Gardiol, 1996), (Vogel Goldhirsh, 1986) and (LaGrone, 1977). Trees are able to attenuate the signal to the order of 10 dB (Vogel Goldhirsh, 1986). The Monte Carlo methods even though are good when adequate measured data is used, suffers from modifications to the buildings and terrains and are very expensive to carry out. Empirical methods make use of information gathering on the basis of systematic experimentation instead of making use of logic or mathematics. The empirical model uses extensive measured data and analysis tools to formulate relationship between parameters of interest. Measurements have shown that a simple two-ray model consisting of the direct and the ground-reflected ray was sufficient to predict the path gain (loss) for propagation over a flat earth (Rustako, Jr., Owens, Roman, 1991) and (Xia, Bertoni, Maciel, Lindsay-Stewart, Rowe, 1993). Reflection occurs when the wave from a source hit an object whose dimension is large as compared to the wavelength of the wave. The path loss represents the signal attenuation in decibel (dB). The path loss is the difference between effective transmitter and receiver power. Most published work concerning outdoor propagation depends on free space and two-ray models (Pande, Choudhari, Pathak, 2012), (Willis Kikkert, 2007), (Neto, Neto, Yang, Gl over, 2010). The free space model assumes that both transmitter and receiver, use line-of-sight communication with no obstruction or reflection of any form. The free space model obeys the relation: (2. 1) Where f is the frequency in MHz and d is the separation distance between the transmitting and receiving antennas in meters. The receiver power has been found to falls off as the square of the transmitter-receiver separation distance. The receiver power decays at the rate of 20dB per decade. When the effect of ground ray reflection is considered, a Plane Earth model was used. The model is given as: (2. 2) Where d is the distance as above and and are the elevations of the transmitter and receiver heights in meters respectively. The separation distance (d) in this model is assumed to be much larger than and .In our real environment today, there are obstruction everywhere and the propagation of the electromagnetic waves are affected by it (Mao, Anderson, Fidan, 2007). The radio signals in our environment are attenuated by reflection, diffraction and scattering. Scattering occurs when an object in a medium are smaller as compared to the wavelength of the incoming wave. To be able to account for location characteristics and the impact of vegetation, it was found in literature that the average signal power decreases logarithmically with distance (Rappaport, 2002). To be able to estimate the path loss due to real world approximation, a log-distance model was developed. The average path loss for a typical distance between a transmitter and a receiver can be represented as an expression of distance by using the exponent n. The path loss is given as (Liao Sarabandi, 2005): (2. 3) Where is the path loss in dB at a reference distance and n is the path loss exponent that represent the rate of the path loss decrease as a function of distance. The value n also characterizes the propagation environment. Table 2.0.2 below summarizes the characteristic of the exponent n in the environment. Table 2.0.2. Characteristics of typical propagation environments Environment Path loss exponent values (n) Free space 2.0 Urban area, cellular radio 2.7 to 3.5 Shadow Urban cellular radio 3.0 to 6.0 In-buildings, line-of-sight 1.6 to 1.8 Obstructed in buildings 4.0 to 6.0 Obstructed in factories 2.0 to 3.0 The reference distances from research was taken to be between 100 m to 1 km depending on the height of the transmitter. The International Telecommunication Union (ITU) recommended that in a situation where majority of the signal propagates through trees or vegetation, the ITU-R model can be used (Rappaport T. S., 1996). (2. 4) Where the frequency used was between 200 MHz and 95 GHz. One of the most important fully empirical prediction method was conducted by (Okumura, Ohmori, Kawano, Fukuda, 1968). Okumuras method was based entirely on an extensive measurement in Tokyo city. Okumura developed a set of curves given the median attenuation relatively to free space in the urban area over a quasi-smooth terrain. From these curves, Okumura deduce from the graphs a simple power law which was a function of the environment and it characteristics. The model was applicable to frequency range between 200 MHz and 2 GHz and covers a distance of 100 km. Okumuras data was further modified by (Hata, 1980) who made it into a series of graphs. However, other methods disagree with the predictions of the Okumuras methods. Others have also tried to improve the method by applying building density (Kozono Watanabe, 1977) but was rejected by the scientific community. The Okumura-Hata model, together with related corrections was found to be one of the most common and single model used in designing real systems. Lee in 1982 came out with a power law model which was based on measurement and takes into account the variation in terrain (Lee, 1982). The model was environment specific because it was based on the assumption of the characteristics of the environment. It will be very difficult to tell which environment characteristics one need to use since the environment varies from one country to the other. Even though empirical method was easy to implement and their ability to include all environment-related factors that affect the propagation of radio waves in practice (Rappaport T. , 2002), they suffer from parameter ranges; the environment must be classified which may vary from one place to the other .the method also do not provides insight into propagation mechanism and analytical explanations. The Physical model method attempt to produce deterministic field strength at specified points. (Ikegami, F.; Takeuchi, T.; Yoshida, S., 1991). The model makes use of characteristics of the environments, physical optics and other theories to account for the intended parameter of interest. A careful assessment of the exposure of urban populations to electromagnetic fields requires the use of deterministic models that take into account the interferences caused by the buildings in the propagation of the field. Deterministic models were developed to account for terrain in the absence of buildings based on geometric theory of diffraction (Bullington, 1977), (Luebbers R. J., 1984) and (Lampard Vu-Dinh, 1993). Other methods such as parabolic equation method (Janaswamy Andersen, 1998) and (Levy, 1990) takes the detail terrain profile into account. The method uses detail map of an area taking into consideration building configurations and using a ray optics to trace the waves. There are 3-D (three dimensional) ray tracing models that are able to accurately estimate site-specific propagation situations (Catedra, Perez, Saez de Adana, Guiterrez, 1998). Although it accounts reasonable well for close in variation of field strength, it suffers from unrealistic assumptions, theories and underestimate in some cases (Saunders, 1999). Other works also uses numerical methods such as method of moments (MOM) to analyze the electromagnetic field of antennas (Johnson, Shin, Eidson, 1997), (Wanzheng, Yan, Anmin, 2000), (Povinelli DAngelo, 1991), (Lou Jin, 2005) and (Tofani, dAmore, Fiandino, 1995). However, these Methods require higher mathematical and programming skills such as large sparse matrix solution as well as more computer resources such as larger memory and multiple CPUs than the analytical method (Johnson, Shin, Eidson, 1997). A semi-analytical treatment has been carried out for cases where the horizontal separation between the base station and first row of building s is knownand all the buildings are of the same height (Xia, Bertoni, Maciel, Lindsay-Stewart, Rowe, 1993), (. Bertoni Maciel, 1992). From the above analysis, it was evident from literature to date that there is no one method which will be able to predict accurately well and also help us understand and make meaning of the physics involved in the process of study. This research work focuses on the need for a hybrid model (Semi-Empirical) which will achieve a good level of accuracy and also help us understand the physical interaction of the parameters involved and also serve as an advancement on this field. 2.6 Advances in measurements The natural electromagnetic energy comes from terrestrial and extra-terrestrial sources such as electrical discharges during thunder storms in the atmosphere and radiation from sun and space. It is of interest to note that the blackbody radiation from a person in the RF-band is approximately 3 mW/m2. The man-made source originates from mainly telecommunication and broadcasting services in the environment. There are several methods developed to assess the electromagnetic fields (EMF) exposure level in literature. One of them was the use of a personal exposure measurement methods (Viel, Cardis, Moissonnier, Seze, Hours, 2009), (Urbinello, Joseph, Huss, 2014), (Bolte Eikelboom, 2012), (Urbinello, Huss, Beekhuizen, Vermeulen, Rà ¶Ãƒ ¶sli, 2014), (Radon, Spegel, Meyer, 2006) and (Frei, Mohler, Bà ¼rgi, 2009). Another method is the used of stationary measurement approach (Bà ¼rgi, Frei, Theis, 2010), (Calin, Ursachi, Helerea, 2013), (Pachà ³n-Garcà ­a, Fernà ¡ndez-Ortiz, . P aniagua-Sà ¡nchez, 2015), (Ozen, Helhel, Colak, 2007), (Korpinen Pà ¤Ãƒ ¤kkà ¶nen, 2015) and (Verloock, Joseph, Goeminne, 2014) where measurement is made at a define period of time such as 6 minutes averaging. The 6-minute averaging time comes from the time constant for the thermoregulation of the body (ICNIRP, 1998) to occur. FM and TV broadcast transmitters, GSM and UMTS base stations are important sources of RF EMF in terms of exposure level in the environment. In general, FM and TV broadcast transmitters were installed in places far off distance from the city center in the past but in todays world, they are installed within our communities. In 1980, Tell and Mantiply published a study of RF fields measured at 486 sites across 15 major metropolitan areas in the USA which at that time, accounted for nearly 20 % of the nations population of 226.5 million people (Tell Mantiply, 1980). The measurements covered the low VHF TV (54-88 MHz), FM radio (88-108 MHz), high VHF TV (174 -216 MHz) and UHF TV (470-806 MHz) bands. They reported a median wideband time-averaged field level of 0.005 mWcm-2, with an estimated 1 % of the population exposed to fields with power densities of 1 mW cm-2. In addition, the fields from FM radio broadcasts were clearly dominant over the fields from the other three bands. Typically for High-power broadcast transmitters, the effective radiated power (ERP) was 250 kW per channel for FM radio and 500 kW per channel for television. The antennas were mounted towards the top of a 300 m mast. For medium-power broadcast and telecommunications transmitters, the transmitted powers were in the region of 100-200 W per channel. The exposure to the general public was very small relatively to people living in the immediate neighborhood of medium and short-wave stations (Jokela, Puranen, Gandhi, 1994). People working in FM and TV towers which are near to high power FM or TV broadcast antennas were exposed to high levels in the range of 50 to 800 MHz (Jokela Puranen, Occupational RF exposures, 1999) and (Hansson-Mild, 1981). Other studies have been carried out in the domains of exposure field measurement by (Viel, et al., 2009a), (Viel J. , Cardis, Moissonnier, R., Hours, 2009b) and possible consequences of human exposure to such fields(Hossmann Hermann, 2003). A study of ambient RF fields conductedmostly outdoors in Gothenburg, Sweden reportedan average wideband power densities of between 0.04and 0.05 mW cm-2 (Ahlbom, Feychting, Hamnerius, Hillert, 2012).European studies reported generally, in the five-country analysis, the totalexposures were lowest in the urban residential environment(range of means 8.5E-03 to 1.45E-02  µW cm-2). The results for a set of African countries was qualitatively and quantitatively similar to the results of RF measurement surveys conducted in the Americas, Europe and Asia (Rowley Joyner, 2012) where the global weighted average was 0.073 mW cm-2. The mean for the selected South Africa n data set was 0.016 mW cm-2. Some of the conclusion drawn was that the signal strengths for the cellular bands was unchanging in both time and across countries. Even though introduction of 3G and 4 G services are on the increase, the field levels are log-normally distributed and more data points makes the FM signal strengths relatively constant. In addition to these findings, several studies have reported that residential (and outdoor) fields from broadcast and cell downlink sources are lower in rural areas compared with fields in urban and suburban areas (Breckenkamp, et al., 2012), (Viel, et al., 2009a) and (Joseph, Vermeeren, Verloock, Heredia, Martens, 2008). Cancer has been the primary concern among populations in the immediate vicinity of broadcast transmitters. Scientific evidences point toward heating effect from high levels of exposure, and most safety limits are based on it. Among these are the exposure limits proposed by the International Commission for Non-Ionizing Rad iation Protection (ICNIRP) (ICNIRP, 1998) or Institute of Electrical and Electronics Engineers (IEEE) (IEEE, 2005) to prevent such effects (WHO, 2006).There is little scientific evidence on the risks associated with long-term exposure to low levels of RF EMF (ICNIRP, 1996). In 2012, the International Agency for Research on Cancer classified RF EMF as possibly carcinogenic (Group 2B), based on studies on mobile phone usage (IARC, 2012). Mobile phone usage has increased tremendously, with about 6.8 billion subscriptions by the end of 2013 (ITU, 2013) and nearly 7 billion cell phone subscribers in 2014 (ITU). Statistics show that as at May 2008, the number of mobile phone users in Ghana was well over 8 million but as at the end of January 2016, the number of mobile phone users in Ghana rose to 26.09 million, according to the latest figures from the National Communications Authority (NCA). Urban areas are mostly affected by the over population of Base Station Transceivers (BTSs). Their closeness to homes and schools are raising concern about some health risks that might be associated with them (Khurana, et al., 2010). Numerous studies have demonstrated that a very significant part of the human exposure in the radiofrequency (RF) band is due to mobile communications radiation (Bornkessel, Schubert, Wuschek, Schmidt, 2007), (Genc, Bayrak, Yaldiz, 2010), (Joseph, Verloock, Goeminne, Vermeeren, Martens, 2010), (Kim . Park, 2010), (Rufo, Paniagua, Jimenez, Antolà ­n, 2011), (Joseph, W.; Verloock, L.; Goeminne, F.; . Vermeeren, G; Martens, L., 2012a), (Joseph, W.; Verloock, L.; Goeminne, F.; Vermeeren, G.; Martens, L., 2012b), (Rowley . Joyner, 2012). The maximum output powers of a radio channel used in GSM and UMTS networks are 10-40W and 20-60 W, respectively (Koprivica, Neskovic, Neskovic, Paunovic, 2014).It has been shown t

Females According to Christina Rossetti and Mary Wollstonecraft Essay

Females According to Christina Rossetti and Mary Wollstonecraft What is it that separates and elevates human beings from the rest of the animal world? It is the ability to logically explain an action, decision, or conviction; it is the capacity to reason. As Rousseau states, â€Å"Only reason teaches us good from evil† (Wollstonecraft 238). According to him, as well as countless other intellectuals of the eighteenth and nineteenth centuries, through the exercise of reason men become moral and political agents. Of course, this Enlightenment theory does not include women. Rousseau declares his opinion of the female, â€Å"O how lovely is her ignorance!† (253) The woman is the man's fantasy, the man's student, the man's plaything. Controlled, contained, and defined by the man, the woman is inferior to him and thus, not human. Eighteenth century writer and mother of female liberalism, Mary Wollstonecraft refutes this supposedly natural state of man being superior to woman in her treatise, "A Vindication of The Rights of Woman": It is farce to call any being virtuous whose virtues do not result from the exercise of reason... This was Rousseau's opinion respecting men: I extend it to women....till the manners of the time are changed...it may be impossible to convince [women]that the illegitimate power, which they obtain, by degrading themselves, is a curse, and that they must return to nature and equality ...(239) She proclaims the female to be equally capable of reason as the male. In order for the female to recognize and utilize this capability, society's males and females must alter their prejudicial definition of the feminine. Wollstonecraft addresses the fema... ...cquire virtues which they may call their own, for how can a rational being be ennobled by any thing that is not obtained by its own exertions?† (254) Indeed, it is only when the woman may call her skill, her experience, or her truth, all derived from reason, her own that she shall be independent. As Rossetti states, â€Å"Only my secret's mine...† (6). And, only when the societal norms change, shall the keeping of such a secret be by choice and not necessity. Works Cited Wollstonecraft, Mary.

Laban Movement

Christine Dugan Sheila Buttermore LMA Research Project Inner vs. Outer Connetivity Laban movement analysis is the language of dance and is considered to be sacred geometry that uses five crystallized forms that calculate movement and offers equations through symbols to make sense of everyday movement . By using laban motifs/symbols in an equation, the end product is almost always a dance or a deliberate movement sequence. The ability to use the laban system has made me aware of how I both observe and understand dancing in every sense of the word and idea of movement as I study as a performing arts major at Raritan Valley.The concept of inner vs. outer connectivity is what intrigues me the most so far out of they many interesting facts and ideas taught and spoken about within this semester taking into account that we were exposed to was only the tip of a giant ice berg that is LMA and all that it offers. The simple concept of thinking about, and emotionally feeling a movement and wher e that movement is intended to go through space before actually moving it is something I feel that I have been knowingly over analyzing in all of my years of dancing both in and out of class. Learning about inner vs. uter connectivity brought an awareness and a validity to my understanding of dance along with developing my ability to put inner states into outer expressions. In order to portray a specific emotion or gesture through movement, one must consider their Spatial Intent. â€Å"Spatial Intent is a clarity and specificity of outer destination in movement that has the effect of promoting and organizing inner connectivity†(1) For example, to execute a movement with a heavy intent such as stomping your feet on the ground, thinking of a heavy mass or emotion will allow that stomping to be perceived as an undeniably heavy, weighed action.When dancers have not been introduced to laban’s inner and outer connectivity concept, they are only achieving the technical aspect of the movements that they are taught, failing to connect with the inner dynamics that bring life and intent to performance. An example of how simply this can be taught to even the youngest of dancers would be to have them imagine that they are holding a beach ball in their arms, giving them a mental visualization of the correct placement of where their arms should be.By using laban’s method, this will eventually become an intrinsic component of their movements thereby developing muscle memory and natural inner and outer connectivity. Within one of the books that assisted me throughout my research, â€Å"Body Movement: Coping With The Environment† it states, â€Å" When, however, a specific spatial intent is added, such as a gathering movement of embracing or a scattering movement of repelling particular objects, a new tension is created between the object and the initiation of the movement in the body, and a particular, rather than a general, spatial shape is produc ed as the movement proceeds. (2) This book was a collaboration of Irmgard Bartenieff, the man who created the basic six exercise’s and the BF principals taught in LMA and Dori Lewis from the 19th century. This along with several other quotes and passages once again validated my original thoughts on the simplicity and efficiency of these methods for teaching and ways of thinking of movement. Aside from form and spatial points as well as technique being what makes dance, emotion comes first in order to authenticate and embody what that dance really means to you.Without emotion and purpose behind a dance, there is no inner connectivity to transcend out onto those watching you move. It is not hard to tell the difference between watching a dancer who is committed and invested in the movements they are making from head to toe and seeing the purposeful look in their eyes as they follow the direction they are moving, compared to a dancer who seems to appear somewhat jumbled up in the ir movement, displaying lack of directional intent and body connectivity with a blank look on their face and without emotion in their eyes.Audiences universally go to see performances with the intention of having an emotional experience whether it be happy, sad, funny, ect. It is up to the performers to fulfill those expectations. It is through the skill and inner and outer connectivity of the performers that these expectations can be met. It is with the knowledge that I have gained through learning about Laban’s theories and concepts that will allow me to have a new level of awareness and sense of connection.I will apply what I have learned with a conscious effort to implement my body connectivity both inner and outer as well as how I portray my movements as I go forward in dance. Studying Laban theories and concepts has given me a deeper appreciation of both performance and everyday movement. I look forward to continuing my understanding of this amazing language of dance th at was created by Rudolph Laban, who made an intangible art from, tangible.

Anatomy Of The Periodontium Sciences Essays

Anatomy Of The Periodontium Sciences Essays Anatomy Of The Periodontium Sciences Essay Anatomy Of The Periodontium Sciences Essay The periodontium is defined as the tissues puting and back uping the dentition ( Hassell, 1993 ) . It is composed of the undermentioned tissues: alveolar bone, root cementum, periodontic ligament and gum ( Lindhe et al. , 2008, Hassell, 1993 ) . The chief map of the periodontium is to attach the tooth to the bone of the jaws for equal map and to keep the unity of the surface of the masticatory mucous membrane of the unwritten pit ( Lindhe et al. , 2008 ) . It undergoes alterations with age, and is subjected to morphologic alterations in relation to functional changes and changes in the unwritten environment ( Lindhe et al. , 2008 ) . The healthy gum usually covers the alveolar bone and root to a degree merely coronal to the cementoenamel junction ( Fig. 1 ) . The gum is classified into the free fringy gum, the interdental gum and the affiliated gum ( 187 ) . Gingivas are portion of the soft tissue liner of the oral cavity. They surround the dentitions and supply a seal around them. Compared with the soft tissue liners of the lips and cheeks, most of the gum are tightly bound to the underlying bone and are designed to defy the clash of nutrient passing over them ( Lindhe 2008 ; Narayanan 1996 ) . Healthy gum is normally coral pink, but may incorporate physiologic pigmentation. Changes in colour, peculiarly increased inflammation, together with hydrops and an increased inclination to shed blood, propose an redness that is perchance due to the accretion of bacterial plaque ( Capa N, 2007 ) . The gum is divided anatomically into fringy, affiliated and interdental countries. The fringy gum is the terminal border of gum environing the dentition. In about half of persons, it is demarcated from the adjacent, attached gum by a shallow additive depression, the free gingival channel ( Capa N, 2007 ) The fringy gum is supported and stabilized by the gingival fibres. The affiliated gum is uninterrupted with the fringy gum. It is steadfast, resilient, and tightly bound to the underlying periosteum of alveolar bone. The facial facet of the affiliated gum extends to the comparatively loose and movable alveolar mucous membrane, from which it is demarcated by the mucogingival junction. Attached gum may show with surface stippling ( Schroeder HE, 1997 ) The interdental gum occupies the gingival port, which is the interproximal infinite beneath the country of tooth contact. The interdental gum can be pyramidic or have a gap shape.Attached gum is immune to masticatory forces and ever keratinised ( Stephen Burke Dent IV, 1994 ) . Healthy gum normally has a colour that has been described as coral pink. Other colorss like ruddy, white, and blue can mean redness ( gingivitis ) or pathology. It has a smooth arcuate or scalloped visual aspect around each tooth. It besides fills and fits each interdental infinite, unlike the swollen gum papilla seen in gingivitis or the empty interdental port seen in periodontic disease. Healthy gum clasp tight to each tooth in that the gingival surface narrows to knife-edge thin at the free gingival border. On the other manus, inflamed gums have a puffy or rolled border. It has a steadfast texture that is immune to motion, and the surface texture frequently exhibits surface stippling. Unhealthy gum, on the other manus, is frequently conceited and mushy ( Seyedmajidi M, 2009 ) . The gingival fibres are the connective tissue fibres that inhabit the gingival tissue adjacent to the dentition and aid keep the tissue steadfastly against the dentition ( Itoiz, ME, 2002 ) . They are chiefly composed to type I collagen, although type III fibres are besides involved These fibres, unlike the fibres of the periodontic ligament, in general, attach the tooth to the gingival tissue, instead than the tooth to the alveolar bone ( Schroeder HE, 1997 ) . The gingival fibres hold the fringy gum against the tooth, supply the fringy gum with adequate rigidness to defy the forces of chew without falsifying, function to stabilise the fringy gum by unifying it with both the tissue of the more stiff affiliated gum every bit good as the cementum bed of the tooth ( Itoiz, ME, 2002 ) . There are three groups within which gingival fibres are arranged, they are dentogingival group, round group and transseptal group. The junctional epithelial tissue is that epithelial tissue which lies at the base of the gingival sulcus. It attaches to the surface of the tooth with hemidesmosomes ( W.B. Saunders, 2002 ) . It lies instantly apical to the sulcular epithelial tissue, which lines the gingival sulcus from the base to the free gingival border, where it interfaces with the epithelial tissue of the unwritten cavity.Cells in the junctional epithelial tissue tend to hold broad inter-cellular infinites, to let the transmittal of white blood cells from blood vass to bottom of the gingival sulcus, to assist forestall disease. Damage to the junctional epithelial tissue consequences in it being irregular in texture, instead than smooth, and the formation of pocket epithelial tissue, which is a primary symptom of gingiva disease. The sulcular epithelial tissue is that epithelial tissue which lines the gingival sulcus. It is apically bounded by the junctional epithelial tissue and meets the epithelial tissue of the unwritten pit at the tallness of the free gingival border. The sulcular epithelial tissue is nonkeratinized ( W.B. Saunders, 2002 ) . The periodontic ligament, normally abbreviated as the PDL is a group of specialised connective tissue fibres that basically attach a tooth to the alveolar bone within which it sits. These fibres help the tooth withstand the of course significant compressive forces which occur during mastication and remain embedded in the bone ( Sloan, P, 1978 ; Sloan, P, 1979 ) . Another map of the PDL is to function as a beginning of proprioception, or centripetal excitation, so that the encephalon can observe the forces being placed on the dentitions and react consequently. To accomplish this terminal, there are force per unit area sensitive receptors within the PDL which allow the encephalon to spot the sum of force being placed on a tooth during mastication, for illustration. This is of import because the open surface of the tooth, called enamel, has no such sensory receptors itself. In add-on to the PDL fibres, there is another set of fibres, known as the gingival fibres, which attach the dentitions to their next gingival tissue. Both the gingival fibres, every bit good as the PDL fibres, are composed chiefly of type I collagen ( Ten Cate, A. R, 1998 ) . The PDL is one of the four back uping tissues of a tooth, otherwise referred to as the periodontium. They are about 0.2 millimeters in breadth, and these dimensions lessening with age ( C. Kober, B, 2006 ) . As stated, the PDL fibres are composed chiefly of type I collagen, although type III fibres are besides involved. Compared to most other ligaments of the organic structure, these are extremely vascularized. The PDL fibres are categorized harmonizing to their orientation and location along the tooth, such as collagen fibres, gingival fibres, trans-septal fibres, alveolar crest fibres, horizontal fibres, oblique fibres, apical fibres, and interradicular fibres ( Quigley, M.B, 1970 ; Cohn, S.A, 1972 ; Cohn, S.A, 1972 ) . Cementum is a specialised calcified substance covering the root of a tooth. Cementum is excreted by cells called cementoblasts within the root of the tooth and is thickest at the root vertex. Its colour is xanthous and it is softer than enamel and dentin due to being less mineralized ( Jones SJ, 1972 ) . The chief function of cementen within the tooth is to function as a medium by which the periodontal ligaments can attach to the tooth for stableness. Hence, its bottom surface is tangent to the periodontic ligaments running through the jaw ( via collagen fibres ) , and the upper part of the surface is steadfastly cemented to the dentin of the tooth. It besides meets the enamel lower on the tooth at the cemento-enamel junction. Here the cementum is known as noncellular cementum due to its deficiency of cellular constituents, and screens about 1/3-1/2 of the root ( Groeneveld MC, 1994 ) . The more permeable signifier of cementen, cellular cementum, covers 1/3-1/2 of the root vertex, where it binds to the dentin. There is besides a 3rd type of cementum, afibrillar cementum, which sometimes extends onto the enamel of the tooth. The mucogingival junction is the intervention between the more apically located alveolar mucous membrane and the more coronally located affiliated gum of the air sac ( Schroeder HE, 1979 ) . There exists a mucogingival junction on all four gingival surfaces on which there exists freely impermeable alveolar mucous membrane: the facial gum of the upper jaw and both the facial and linguistic gum of the mandible. The palatine gum of the upper jaw is uninterrupted with the tissue of the roof of the mouth, which is bound down to the palatine castanetss. Because the roof of the mouth is barren of freely movable alveolar mucous membrane, there is no mucogingival junction ( W.B. Saunders, 2002 ) . Mentions Hassell, TM. ( 1993 ) .

Chocolates Positive and Negative Effects

Chocolates Positive and Negative Effects Introduction In the past two decades, chocolate has been considered a junk food due to the way in which its consumption has significantly contributed to the obesity epidemic within the U.S. at the present.Advertising We will write a custom research paper sample on Chocolates Positive and Negative Effects specifically for you for only $16.05 $11/page Learn More Nearly 33% of adults within the U.S. are obese which represents a 60% increase over a 20 year period with the rate for child obesity not far behind at nearly triple what it was 30 years ago. Most of these cases have been attributed to the consumption of large amounts of junk food with chocolate being ranked among the most popular types to be eaten. However, it must be questioned whether chocolate truly deserves to be ranked as a junk food. The fact remains that numerous studies such as those by Howe (2012) have expressed that the consumption of chocolate is in fact beneficial and can aid in enabling a person to attain a healthier body[1][2]. On the other hand, there are studies such as those by Hughes (2012) which state that it is the excess consumption of chocolate that has contributed significantly to obesity within the country[3]. It is based on this that this paper will examine aspects related to the current junk food culture, the portrayal of the media about junk food and chocolate as well as current academic literature surrounding the consumption of chocolate. The researcher expects that through this investigation a clearer picture can be seen regarding the nature of chocolate. It is the assumption of this study that chocolate can be considered a junk food depending on the quality and the quantity that has been eaten. The Age of the Junk Food Culture Junk food in the form of chips, dips, burgers, fries, sodas, candies and ice cream have become such a part of Americas culture that the most prevalent cultural distinction for American today is that of the Junk Food culture. Th e term junk food is actually a terminology that was originally developed during the early half of the 1970s to describe the growing proliferation of prepackaged easy to consumer food products that came in disposal wrappers[4]. The low nutritional content of said food products combined with the easy to dispose nature of their wrappings resulted in the creation of the term junk food. In nearly every town, city and state groceries, shopping malls and fast food restaurants carry some form of junk food that is rapidly consumed by a voracious public that enjoys the taste and convenience of such products. Unfortunately, this cultural distinction is actually slowly killing the American population due to resulting effects such food types have one the body. The recommended daily allowance of nutritional calories that a body should have in a single day as recommended by the American Medical Association is roughly 2,500 to 3,000 calories a day[5].Advertising Looking for research paper o n health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More The problem with junk food is that due to their convenience and serving size most people are not aware that on average they consume more than 3,000 calories a day from the various forms of junk food they eat[6]. An average adult male in the U.S. should consume only 65 grams of fat and 2,500 calories in a single day yet a burger and fries combo meal with a large coke available at the local McDonalds is equivalent to more than 50 grams of fat and 1500 calories within a single sitting[7]. This would not be a problem should that be the only large meal they eat throughout the day however this meal is supplemented by various chips, sodas and various other unhealthy options throughout the day which brings the total calorie count to 4,000 calories or more. Chocolate in particular, due to the current manner in which it is produced, is deceptively packaged to the extent that a single chocolate bar can contain 300 to 400 calories or more. Considering the fact that it would take a considerable amount of chocolate to feel full, normal consumers wind up eating more than they should resulting in the consumption of several hundred excess calories. Journalism and the Portrayal of Scientific Information to the General Public On average nearly 10,000 TV ads appear within a given year which focuses on promoting the products of various restaurants and companies[8]. Children in particular are targeted by fancy commercials advertising sugary sweets through the use of cleverly crafted cartoonish elements in the commercial itself. Since TV advertisements are an extension of popular culture it can be seen that popular culture is one of the primary reasons behind the obesity problem America now faces due to this patronage of products that are not only unhealthy but cause people to become obese as a result of their consumption. The power of advertising should not be underestimat ed since it has been shown that TV ads are one of the best ways to convince people to buy a certain product. From this it can be seen that the causes behind obesity is not merely the fast food culture that Americans find themselves in but also the actions of various corporations that promote with wild abandon their products without taking into consideration the possible ramification on the population. It should be noted though that along with these numerous advertisements come equally numerous articles by journalists which deride and criticize food companies for ruining the health of the present day generation. However, what is lacking in such articles is a truly in-depth examination of the nutritional impact of individual junk food products. What occurs is merely a general critic instead of an examination which attempts to determine whether foods such as chocolate have any generally positive effects[9].Advertising We will write a custom research paper sample on Chocolates P ositive and Negative Effects specifically for you for only $16.05 $11/page Learn More Positive Effects of Chocolate While it may be true that chocolate has become a synonymous aspect of the junk food culture, the fact remains that it has a variety of positive healthy effects on the body. This encompasses effects related to better cardiovascular health, an increased metabolism, and brain stimulation. Not only that, chocolate has also been stated as being a possible anti-depressant as well as possessing anti-cancer and anti-oxidant effects[10][11]. However, its relation as a junk food has been cemented due to the manner in which it is consumed in amounts that are greater than the recommended dietary allowance per day. As it was revealed in the study of Howe (2012), chocolate and its numerous iterations has been mixed and matched with a plethora of substances to the point that its health benefits have been highly diluted through an assortment of brands and products[12 ]. Its health benefits are tempered by extreme amounts of added sugar along with prodigious amounts of carbohydrates and assortment of chemicals[13]. The end result is a product that combines the positive mental stimulation of cocoa with the negative impact of a high fructose corn syrup. It is based on this that it can be stated that any health benefits derived from chocolate depends on the type of chocolate and the amount that is consumed. Thus chocolate can be considered a health food so long as one eats it sparingly and consumes chocolate products that are rich in natural cocoa and have little sugar in them. Conclusion Based on the information and arguments that has been provided in this paper thus far, it can be stated that can be considered a junk food depending on the quality and the quantity that has been eaten.

Astronomy and Quantum Physics - Essay Example The macrocosmic view of astrophysics posits billions of galaxies besides our own, innumerable stars, and planets, and this further points to the fact that we really know little about the universe in our limited, arrogant, ego states of consciousness. The religious view informs this understanding through â€Å"shamanic ecstasy† as Kessler calls it in â€Å"Studying Religion: An Introduction Through Cases,† where he describes the shaman travelling to the heavens and attaining a mystical unitive experience. (Kessler, 2007, p.143) In another way, Kessler suggests that the Buddhist conception of enlightenment may relate to a cosmic experience of being that is related directly to the universe of astrophysics. (Kessler, 2007, p.143-4) Knowing what we do of the nature of the cosmos, with many different possibilities of life, and also understanding Buddhist conceptions of re-incarnation, these two views can combine in a manner that merges the spiritual and physical to see life c ontinuing and developing in different forms across a variety of planets and star systems. The microcosmic view of quantum physics tends to infinite smallness where the astrophysics tends towards infinite expansion. That the two may merge in large cycles of time where the universe expands and then contracts to a single point over periods of billions of millennia or more is a massive concept of time cycles that accords with the Buddhist philosophical standpoint and modern physics.

Thin Layer Chromatography of lipids - Assignment Example The material will dissolve in the solvent and move up the solvent front. (a) A Rf of 1 implies that the compound moved the same distance as the hexane solvent. Therefore, the analyzed compound was highly non-polar because it travelled the same distance as hexane, which is a non-polar solvent. (b) Ethyl acetate is a polar solvent. Mixing it with hexane will reduce the hydrophobic nature of hexane (Nollet & Toldra, 2012). Consequently, the Rf value of the same compound will reduce since it will not fully dissolve in the mixture of hexane and ethyl acetate. The TLC system for phospholipase D reaction will include the enzyme itself, phosphatidylcholine and ethyl acetate as the polar solvent. Phospholipase D will hydrolyze the phosphatidylcholine to phosphatidic acid and choline. Choline is more polar compared to phosphatidic acid; hence, it will move further than the acid. Molybdenum spray will be used to monitor the movement of the separated material. At 2 minute, there is little hydrolysis, which then increases to the sixth minute. Standard phosphatidic will be used as a control in the
