IFRS and GAAP Convergence - Essay Example When the financial statements are available in annual reports, it is the responsibility of the managers to evaluate and discuss results of company performance. External parties use these financial statements to analyze the company’s financial performance. Therefore, external users of financial statements are requires to be familiar with the tools and techniques which are used in financial performance analysis (Needles, Powers and Crosson, 2010, p.1270). Financial analysis includes the analysis of income statement and the assets and liabilities in the balance sheet. It can be done by implementing various tools and techniques such as: common size financial statements, comparative financial statements, ratio analysis, trend analysis, fund flow statement and cash flow statement (Murthy and Gurusamy, 2009, pp.8-9). Accounting Convergence A single set of global accounting standards has to be developed that would be used internationally for international and domestic financial report ing. In order to persuade this practice, the International Accounting Standard Board (IASB) and the US Financial accounting Standard Board (FASB) signed a memorandum of understanding, honoring their commitment towards the convergence of International Accounting Standards and the U.S. ... After the IASB and FASB liberated their disclosure draft on revenue recognition, they got many comments which include the lack of transparency about the transfer of control of services, the accounting for warranties, difficulties in recognizing and separating performance obligations, and the model proposed for licenses of intellectual property. It is found that the proposed standard will cause in the considerable shift in how revenues is documented in many situations. Most respondents believe that the proposed standard will have high impact on their financial reporting and in the process of implementing this standard, additional technology and resources will be required. More or less 41% of the respondent agrees upon the implementation of the IFRS in either 2015 or 2016. Difference between U.S. GAAP and IFRS There are many differences between the U.S GAAP and IFRS rules regarding the revenue recognition, provisions and contingencies, income taxes, leases, financial instruments, intan gible assets, interim financial reporting, and the financial statement presentation. But the most important difference would be in the financial statement presentation. Under the US GAAP rules, normally comparative financial statements are prepared, though a single year may be accessible in certain events. For the public companies, balance sheets for the two most current years are needed, whereas other statements must contain three year period which should be ended on the balance sheet date. Under IFRS rules, comparative information must be revealed with respect to the prior period for all amounts which are shown in the financial statements. Under US GAAP rules,

Individual Critical Reflection on Event and Self Performance Essay

Individual Critical Reflection on Event and Self Performance - Essay Example The Dà ©jà   vu Charity Event was to focus on selling pre-loved second hand clothes donated by the community, to raise money to support the Hospice of St Francis. However, in the course of time, adding cakes sale to the event was found a viable addition to the event, since it would increase both event sponsorship and at the same time increase the amount of money that would be generated through the event. Thus, Tesco’s, Hatfield and friends and family donated the clothes and cakes that were sold during the event. Conducting research into similar models or events can help in determining whether an event is likely to be a success (Bowdin et al 2011). The Hospice of St Francis has nine ‘Love to Give’ charity shops, and thus adopting a similar ‘Love to Give’ charity shops’ model for raising money had a high likelihood of being successful. The event was conducted on Sunday 12th April 2015 at Shendish Manor Hotel, Hemel Hempstead between 10:00 and 1 2:00. The overall outcome of the program can be considered a success. We were able to organize and finally hold the event successfully. The tools that measure the success of an event come into two forms. First, there are the quantitative tools that measure the success of the event in terms of the number of attendants, how much money was contributed during the even t and how big the event was compared to similar events (Sumac, 2015). Secondly, the success of an event is measured in form of quantitative measures that cannot be expressed in numerical form, such the actual outcome of the event vis-à  -vis the targeted outcome is assessed. Thus, the success or failure of any project or event is assessed based on whether the core objectives of the event or project were successfully met (Nelson, 2006). The Dà ©jà   vu Charity Event had established two major objectives that it sought to accomplish, and the two objectives of the event were met.

Performance of Raspberry-Like Gold Nanoparticles (Au RLNPs)

Performance of Raspberry-Like Gold Nanoparticles (Au RLNPs) Improvement of Stability and Catalytic Performance of Raspberry-Like Gold Nanoparticles by Silica Coating High Catalytic Performance of Raspberry-Like Gold Nanoparticles (Au RLNPs) and Enhancement of Stability by Silica Coating Kiouk Seo, Hien Mai Duy and Hyojong Yoo* Abstract. The raspberry-like gold nanoparticles (Au RLNPs) synthesized through the reduction of HAuCl4 by the use of NaOH and Brij35 surfactant show high catalytic activities in the reduction of 4-nitrophenol and ethanol electrooxidation. The enhanced catalytic activities of Au RLNPs are mainly due to their high surface area. However, Au RLNPs easily change to the spherical or aggregated nanoparticles in a treatment with acids, thiols, and cationic surfactants (ex, CTAB)), and are difficult to sustain the catalytic activities. To improve the stability and applicability, Au RLNPs core–silica shell nanoparticles (Au [emailprotected]2 NPs) were successfully synthesized in solution without losing their original morphologies through a simple solution-phase sol-gel process with the assistance of surface-stabilizing polymeric agent (Polyvinylpyrrolidone (PVP)). In comparison with Au RLNPs and other Au nanoparticles, Au [emailprotected]2 NPs could be more easily recovered and recycled in the repeated catalytic reactions. Keywords Raspberry-like gold nanoparticles (Au RLNPs), Silica coating, Catalytic reduction, Ethanol electrooxidation, Polyvinylpyrrolidone (PVP) 1. INTRODUCTION Noble metals have gained much attention over the past two decades due to their potentials in a wide variety of applications including energy conversion[1][2], chemical and biological sensing[3], and bioengineering[4]. Tremendous research efforts have been devoted towards the exploration of how to design nanomaterials with varied topographies that has led to the discovery of their fundamental size-, shape-, and component-dependent properties and the development of new applications[5][6][7]. Moreover, it has theoretically and experimentally found that arrays of asymmetric surface features, particularly deviations from spherical geometry, mainly impart unique anisotropy in material properties7. Apparently, to achieve such desired anisotropic topographies strict control is required. Conversely, this leads to a generation of particles with novel properties from the same materials by simply tuning the particle morphology. Furthermore, anisotropic geometry offers numerous unique features an d functionalities that are either difficult to obtain or even hardly obtained by simple size-tuning in spherical counterparts. Morphology of nanoparticles also strongly affects the catalytic performance. This is due to the surface anisotropy possessing a high density of low-coordinated atoms such as steps, edges, and defects serving as catalytically active sites which can markedly affect chemical and physical properties of nanoparticles[8]. Among those colloidal gold (Au) nanoparticles exhibit not only highly tunable architecture-dependent optical properties but also show excellent performance and high selectivity in a variety of heterogeneous green catalytic processes [ref][9][10]. For a better stability, catalytic performance, and reusability of Au nanoparticles, engineering new nanocatalyst system is thus considered one of the most critical tasks. Recently, in our group, we successfully synthesized raspberry-like gold nanoparticles (Au RLNPs) with rich edges and high surface areas through the reduction of HAuCl4 by Brij35 surfactant under basic condition in a controllable fashion [ref]. The synthesized Au RLNPs possess high surface areas and show the unique, highly-red shifted surface plasmon resonances (SPRs) due to the rough, raspberry-like surface of Au RLNPs. These structures also have high surface energies due to their plenty of tips and edges. These nanoparticles are stable and retain their raspberry-like geome try in basic or neutral conditions; however gradually reshape to the spherical geometry under a specific circumstance such as acidic condition. In order to exploit the unique shape-dependent properties of the Au RLNPs in a variety of catalytic applications, further modifications of nanoparticles such as endowing core-shell structure are thus required. Metallic nanostrutures of several different shapes have been coated with silica since the silica shells used as the coating material show substantial enhancement in the stability of the metal cores, particularly in aqueous solvents. Moreover, metallic nanostructured surface can readily functionalized by subsequently coating with silica and using silane-coupling reactions [ref]. Additionally, silica shells are chemically inert, transparent in the visible and IR regions of the spectrum, and readily converted to mesoporous layer [11]. For the direct encapsulation of Au nanoparticles within silica shells, the conventional techniques is employing coupling agents with silane group for the growth of silica shells on the surfaces of as-synthesized Au nanoparticles via the Stà ¶ber method [ref]. However, we experimentally found that directly applying this method to coat Au RLNPs brought challenges since the unusual size changes of Au RLNPs without disturbing the rough surface occurred. Herein, we report the synthesis of Au [emailprotected]2 NPs in solution through a simple solution-phase sol-gel process. To protect the high-energy surface of Au RLNPs, Polyvinylpyrrolidone (PVP) was used prior to the condensation of TEOS as a polymeric stabilizer. Au [emailprotected]2 NPs showed great enhancement in stability under the strongly acidic condition. The catalytic performance, recovery, and reusability of both Au [emailprotected]2 NPs and Au RLNPs were investigated using the reduction reaction of 4-nitrophenol (4-NP) as a reaction model. We also found that and Au RLNPs were capable of electrocatalyzing alcohol oxidation reactions in alkaline media. 2. EXPERIMENTAL DETAILS 2.1. Reagents Polyoxyethylene glycol dodecyl ether ((C2H4O)23C12H25OH, Brij35, Acros Organics), hydrogen tetrachloroauratetrihydrate (HAuCl4†¢3H2O, 99.9%, Sigma–Aldrich), polyvinylpyrolidone ((C6H9NO)n, PVP10, average mol wt 10,000, Sigma–Aldrich), 4-nitrophenol (O2NC6H4OH, 99%, Sigma–Aldrich), sodium hydroxide (NaOH, 97%, Sigma–Aldrich), ammonium hydroxide (NH4OH, 28-30 wt % ammonia, Sigma–Aldrich), tetraethyl orthosilicate (Si(OC2H5)4 98%, Sigma–Aldrich), hexadecyltrimethylammonium bromide ((C16H33)N(CH3)3Br, 99%, Acros Organics), (3-mercaptopropyl)methyldimethoxysilane (CH3Si(OCH3)2CH2CH2CH2SH, 95%, Alfa Aesor), HCl, HNO3, and ethyl alcohol were used as received. All stock solutions were freshly prepared before each reaction. Prior to use, all glassware was washed with Aqua Regia (volume ration of 3:1 of concentrated HCl and HNO3; Caution: Aqua Regia is highly toxic and corrosive and must be handled in fume hoods with proper personal protection equ ipment) and rinsed thoroughly with deionized water. 2.2. Synthesis of raspberry-like gold nanoparticles (Au RLNPs) Au RLNPs with the mean size of approximately 60-70 nm were prepared according to our previous literature [ref]. Briefly, an aqueous Brij35 solution (1 mL; 19.3 wt%) was well mixed with NaOH (aq) (100  µL; 100mM) by shaking for 30 seconds. To this mixture, HAuCl4 (aq) (50  µL; 10 mM) was added, and shaken vigorously for 1 minute. The pale yellow reaction mixture then turned to blue within 5 minutes at room temperature. To make sure a complete reaction, this mixture was allowed to react for over 20 minutes before being collected by centrifugation (5 min; 13500 rpm), and redispersed in deionized water. 2.3. Synthesis of Au RLNPs@SiO2 NPs The preparation of Au [emailprotected]2 NPs was as follows: firstly, the as-synthesized Au RLNPs were dispersed in 1 mL of deionized water. Next, 0.235 mL polyvinylpyrrolidone (PVP10) aqueous solution (128 mg of PVP10 in 10 mL of deionized water) was added to the Au RLNPs solution. The resulting mixture was then stirred at room temperature for 12 hours to ensure complete adsorption of PVP on Au RLNPs. Afterward, the PVP-capped RLNPs were purified by centrifugation (5 min; 13500 rpm), and redispersed in solvent mixture containing 1 mL deionized water and 7 mL ethyl alcohol. In the next step, tetraethylorthosilicate (TEOS, 0.03 mL) and ammonium hydroxide (0.2 mL of 14.8 M NH4OH (aq.)) were sequentially added to the PVP-capped Au RLNPs aqueous solution and the reaction mixture was further stirred at room temperature for 4 h. After the completion of the reaction, the resultant Au [emailprotected]2 NPs were centrifuged, and purified by repeatedly washing in ethanol and centrifugation. 2.4. Catalytic reduction of 4-nitrophenol The catalytic reduction of 4-nitrophenol (4-NP) over nanoparticles in the presence of NaBH4 was carried out to assess the catalytic activity. In a typical experiment, 2 mL of deionized water, 1.7 mL of 0.2 mM 4-NP, and 1 mL of 15 mM NaBH4 solutions were mixed in a quartz cuvette followed by the addition of 1 mL of Au [emailprotected]2 NPs solution. The color of solution changed gradually from yellowish to clear as the reaction proceeded. UV-Vis spectra were recorded at a 5-minute intervals to monitor the progress of the reaction. 2.5. Ethanol electrocatalytic oxidation All electrochemical measurements were carried out in a conventional three-electrode cell at ambient temperature (~25ËÅ ¡C) using WPG 100e Potentiostat (WonAtech Inc.). The fabrication of working electrode is as follow: Prior to electrochemical experiments, glassy carbon (GC) electrode was sonicated in ethanol and deionized water successively. 10  µL of RLNP suspension was dropped onto carbon disk and the solution is dried at room temperature. Platinum and Ag/AgCl were employed as counter and reference electrodes, respectively. With an aqueous mixture of 0.5 M KOH and 1.0 M ethanol as electrolytes, at least 10 cycles of cyclic voltammetry were carried out before recyclable voltammograms were recorded. Throughout the cyclic voltammetry experiments, the potential window was between -0.2 V and 0.8 V. Prior to experiments, the electrolytes were degased by bubbling with nitrogen for 30 min. 2.6. Characterization The nanoparticles were imaged using a Hitachi S-4800 scanning electron microscope (SEM), and a JEOL JEM-2010 Luminography (Fuji FDL-5000) Ultramicrotome (CRX) transmission electron microscope (TEM). Samples were prepared for TEM by concentrating the nanoparticle mixture by centrifuging twice for 5 min at 13500 rpm with resuspension in 100 ÃŽ ¼L nanopure water and immobilizing 10 ÃŽ ¼L portions of the solution on Formvar-coated Cu grids. Extinction spectra were recorded with a UV-vis spectra spectrometer (UVIKON XS). Solution pH was measured using an Orion 420 A+ pH meter. 3. RESULTS AND DISCUSSION Initially, the highly monodisperse Au RLNPs with controlled diameters ranging from 60 to 70 nm (Fig. 1a and S1) [Images and size distribution of RLNP] were prepared according to protocols developed previously.ref Polyvinylpyrrolidone (PVP) was then employed as a primer and a direct growth of silica onto the PVP-capped Au RLNPs to obtain Au [emailprotected]2 NPs was carried out using solution-phase sol-gel method with TEOS as a precursor. PVP, which have been often used as a surface-stabilizing polymeric agent to prepare spherical Au core – SiO2 shell nanoparticles,ref was used to protect the high-energy surface of Au RLNPs. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images of Au [emailprotected]2 NPs (Fig. 1b-d) show the well-established core-shell structure in which the as-synthesized Au RLNPs were uniformly and individually encompassed within silica shells whereas still sustaining their rough and edge-rich surfaces advantageous to catal ytic performance. The average diameter of individual Au [emailprotected]2 NPs was xxxxx (xxx particles was evaluated, Fig 1e). With respect to RLNPs cores, the average size was nearly similar to that of RLNPs before silica-coated (Fig S1). The UV-Vis spectra plotted in Fig. 1f, a noticeable broadeness in the corresponding surface plasmon bands in Au [emailprotected]2 NPs compared to that of Au RLNP were observed. It is well know that the weaker and broader surface plasmons are observed,, due to the change of refractive index of surrounding environment after silica coating step[b1].ref [Fig 1] High catalytic efficiency of Au nanocatalysts were mainly due to their high roughness and plethora of edge-rich surfaces and corners.ref Thus it necessitates assessing whether catalytically active surfaces of the synthesized nanoparticles are stable in various environments. HCl, CTAB, and MPTS were introduced into the colloidal solution of the as-synthesized RLNPs in order to understand the stability of Au RLNPs in different ambiences. Fig. 2 shows typical SEM images displaying changes in geometries of Au RLNPs as adding diverse reagents. It is experimentally observed that Au RLNPs collectively changed to spherical nanoparticles with the smooth surface as adding HCl (Fig S2)ref corresponding to a blue-shift in UV-Vis spectrum toward approx. 520 nm which can be assigned to the surface plasmon resonance (SPR) of gold nanospheres. This phenomenon could be attributed to the oxidative etching effect which has been employed to control the size of other noble nanostructures in recent papers [12] [13] [14]. Meanwhile, as shown in Fig. 2a, much agglomeration occurred as adding CTAB. However, it is interesting to note that the aggregation also occurred without disturbing their raspberry-like motifs, as adding MPTS (Fig. 2b). The SPR changes shown in UV-Vis spectra (Fig. 2e) further confirmed this aggregation. The introduction of such reagents, which might affect the hydrodynamic layer thickness of Au RLNPs, accounts for this unusual alteration in particles size. The [emailprotected]2 NPs however exhibited no geometrical change when HCl was added. As shown in Fig. 3a, SEM images show that the [emailprotected]2 NPs still retained their original raspberry-like morphology without any observable agglomeration. This observation is also consistent with results obtained from UV-Vis spectra (Fig. 3b) that there was no detectable shift in SPR peak of the core-shell nanoparticles after HCl had been added. Ethanol comprises a lower toxicity, a higher theoretical energy density (8.01 kW.h kg-1) than methanol (6.09 kW.h kg-1) and formic acid (1.74 kW.h kg-1), and fewest environmental issues[15] [16]. Moreover, ethanol is a renewable source that can be easily produced massively from the chemical industry or fermentation of biomass. In this study, electrooxidation of ethanol [HM2]in KOH solution was performed to probe relative electrocatalytic activities of the synthesized nanoparticles. Fig. 4 shows the cyclic voltammograms of RLNPs, HCl-etched RLNPs[HM3], and [emailprotected]2 NPs for ethanol electrooxidation. It is clear that the RLNPs exhibit almost substantially higher electrocatalytic performance with a forward oxidation current (iF) value of 0.56 mA compared to that for HCl-etched RLNPs (iF, 0.07 mA). The high electrocatalytic activity of the RLNPs is attributed to the existence of high energetic surfaces in raspberry-like morphologies. However, [emailprotected]2 NPs did not show an y electrocatalytic activities over the entire potential window. This is explained that silica shells hindered the electron transfer between gold cores and electrode due to silica shells are insulating. The catalytic reduction of 4-NP to their corresponding derivatives, 4-aminophenol, in the presence of NaBH4 was chosen as a model reaction in order to evaluate the catalytic activity of Au [emailprotected]2 NPs. It is well established that the reduction of 4-NP by NaBH4 is thermodynamically feasible but kinetically restricted without a catalyst. The reduction progress was monitored by UV-Vis absorption spectra after the addition of catalysts. The characteristic absorption peak of 4-NP aqueous solution was located at 400 nm after NaBH4 had been added. First of all, in the absence of catalysts the reduction reaction of 4-NP did not proceed even with a large excess of NaBH4. However, when catalysts were introduced, the reduction of 4-NP was clearly observed. The absorbance of the reaction mixture at 400 nm gradually decreased as the reaction proceeded, along with the concomitant increase of 300 nm peak, corresponding to 4-aminophenol. Fig. 4 illustrates the UV-Vis spectra changes of 4-N P as a function of reaction time in the presence of Au RLNPs (Fig. 4a) and Au [emailprotected]2 NPs (Fig. 4c). Fig. 4e shows the change in concentration of 4-NP was plotted versus time, providing a general view to compare catalytic activities of Au RLNPs and Au [emailprotected] ­2 NPs (Ct: absorbance of 4-NP at specific reaction time, t; C0: initial absorbance of 4-NP as catalysis starts). The Ct/C0 is measured from the relative intensity of absorbance (At/A0). As can be seen, Au RLNPs exhibited comparatively higher catalytic activity than their core-shell counterparts, possibly owning to silica shell hindering the diffusion of reactants onto inner gold active sites. Interestingly, in the presence of HCl, the catalytic activity of Au [emailprotected]2 NPs however was not only improved, but also dramatically higher than that of Au RLNPs which was suffering from the morphological change, leading to severe degradation of active sites (Fig. 4e). In addition, we also investigated the d egree of reusability of the two catalysts. As shown in Fig. 5, the catalytic efficiencies of Au RLNPs decreased remarkably after reused 3 times whilst Au [emailprotected]2 still retained good catalytic performance for as far as 7 cycles. It is apparent that the stability and reusability of Au RLNPs were improved significantly after encapsulated into silica shell, resulting in maintenance in their catalytic activity. 4.

Contradictory Impulses in Chopin’s The Awakening Essay -- Chopin Awake

Contradictory Impulses in Chopin’s The Awakening â€Å"Edna Pontellier could not have told why, wishing to go to the beach with Robert, she should in the first place have declined, and in the second place have followed in obedience to one of the two contradictory impulses that impelled her. A certain light was beginning to dawn dimly within her,--the light which, showing the way, forbids it,† (Chopin 34). The possibility of a life beyond the scope of motherhood, social custom, standards of femininity, and wifedom characterize Kate Chopin’s vision of her heroine’s awakening, but Edna’s personal growth remains stifled by her inability to reconcile the contradictory impulses pulling her in different directions. Edna clearly envisions herself somewhere between mother-goddess figure Adele Ratignolle and the artist-spinster Mademoiselle Reisz, yet can not seem to negotiate a space that affords the luxury of love unspoiled by self-sacrifice and obligation. Edna’s â€Å"soul† surfaces when she allows herself to act on impulse over duty, but as Chopin’s words reveal, Mrs. Pontellier blindly fol...

Food And Us Essay

Introduction Food is any substance consumed to provide nutritional support for our body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism’s cells in an effort to produce energy, maintain life, or stimulate growth. Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry. Food and the nutrients obtained from food are vital to keep the body healthy and alive. Nutrients are required in order to build and repair cells and body tissues, maintain the organs and bones in optimum working condition and to provide energy, fuel and warmth. Good nutrition is essential for good health and eating nutritious food can help to prevent against common ailments, as well as more life threatening illnesses and diseases. Foods from plant sources Food sources All food has its origin in plants. Some food is obtained directly from plants; but even animals that are used as food sources are raised by feeding them food derived from plants. Cereal grain is a staple food that provides more food energy worldwide than any other type of crop. Maize, wheat, and rice – in all of their varieties – account for 87% of all grain production worldwide. Most of the grain that is produced worldwide is fed to livestock. Other foods not from animal or plant sources include various edible fungi, especially mushrooms. Fungi and ambient bacteria are used in the preparation of fermented and pickled foods like leavened bread, alcoholic drinks, cheese, pickles, kombucha, and yogurt. Another example is blue-green algae such as Spirulina.[3] Inorganic substances such as baking soda and cream of tartar are also used to chemically alter an ingredient. Below are pictures of Oats, barley, and some food products made from cereal grains, Maize, Wheat and Rice. Food From Plants Many plants or plant parts are eaten as food. There are around 2,000 plant species which are cultivated for food, and many have several distinct cultivars. Seeds of plants are a good source of food for animals, including humans, because they contain the nutrients necessary for the plant’s initial growth, including many healthful fats, such as Omega fats. In fact, the majority of food consumed by human beings are seed-based foods. Edible seeds include cereals (maize, wheat, rice, et cetera), legumes (beans, peas, lentils, et cetera), and nuts. Oilseeds are often pressed to produce rich oils. [pic] Varieties of soybean seeds, a popular legume and freshly dug peanuts Fruits are the ripened ovaries of plants, including the seeds within. Many plants have evolved fruits that are attractive as a food source to animals, so that animals will eat the fruits and excrete the seeds some distance away. Fruits, therefore, make up a significant part of the diets of most cultures. Some botanical fruits, such as tomatoes, pumpkins, and eggplants, are eaten as vegetables. Vegetables are a second type of plant matter that is commonly eaten as food. These include root vegetables (potatoes and carrots), bulbs (onion family), leaf vegetables (spinach and lettuce), stem vegetables (bamboo shoots and asparagus), and inflorescence vegetables (globe artichokes and broccoli and other vegetables such as cabbage or cauliflower) Varieties of Fruits and Vegetables Food From Animals Animals are used as food either directly or indirectly by the products they produce. Meat is an example of a direct product taken from an animal, which comes from muscle systems or from organs. Food products produced by animals include milk produced by mammary glands, which in many cultures is drunk or processed into dairy products (cheese, butter, et cetera). In addition, birds and other animals lay eggs, which are often eaten, and bees produce honey, a reduced nectar from flowers, which is a popular sweetener in many cultures. Some cultures consume blood, sometimes in the form of blood sausage, as a thickener for sauces, or in a cured, salted form for times of food scarcity, and others use blood in stews such as jugged hare. Some cultures and people do not consume meat or animal food products for cultural, dietary, health, ethical, or ideological reasons. Vegetarians do not consume meat. Vegans do not consume any foods that are or contain ingredients from an animal source. Fish also provides a good source of high quality protein and contains many vitamins and minerals. It may be classed as either whitefish, oily or shellfish. Various meet types, animal products and Fish. Why We Need Food Food is important for humans because it contains all the nutrients and vitamins that we need in order for us to function correctly. If we didn’t eat food then we would become too skinny and ill, we would constantly be weak and we wouldn’t be able to grow. To be healthy, we must have enough food and the right kinds of foods. Not enough food, not enough different kinds of food, and even too much food can make us unhealthy. How much is just enough food? People need different kinds and amounts of food. We need more food if we are in a stage of growth, such as infants, children and pregnant and breastfeeding mothers are. We need more food if we work and play hard. And we may need more food if we are sick. Your body needs fuel to run. That fuel comes from nutrients. Nutrients come from food. There six classes of nutrients found in food. They include: carbohydrates fat, protein, vitamins, minerals, and water. By giving your body the proper amounts of nutrients and energy, you’re giving yourself a better chance at staying healthy. Healthy Foods Healthy Foods vs. Unhealthy Foods Healthy eating means consuming the right quantities of foods from all food groups in order to lead a healthy life. Diet is often referred to as some dietary regimen for losing weight. However, diet simply means what food we eat in the course of a 24-hour, one week, or one month, etc. period. A good diet is a nutritional lifestyle that promotes good health. A good diet must include several food groups because one single group cannot provide everything a human needs for good health. The crucial part of healthy eating is a balanced diet. A balanced diet – or a good diet – means consuming from all the different good groups in the right quantities. Nutritionists say there are five main food groups – whole grains, fruit and vegetables, protein, diary, and fat & sugar. Unhealthy or Junk food is an informal term applied to some foods that are perceived to have little or no nutritional value (i.e. containing â€Å"empty calories†); to products with nutritional value, but also have ingredients considered unhealthy when regularly eaten; or to those considered unhealthy to consume at all. Junk foods are typically ready-to-eat convenience foods containing high levels of saturated and / or trans fats, salt, or sugar, and little or no fruit, vegetables, or dietary fiber; and are considered to have little or no health benefits. Common junk foods include salted snack foods like chips (crisps), candy, gum, most sweet desserts, fried fast food and carbonated beverages (sodas) as well as alcoholic beverages. High-sugar cereals, particularly those targeted at children, such as Fruit candies, are also classified as junk food. Summary In summary, we need to understand that our bodies are like a machine.

A look into Wide Sargasso Sea Essay

In what appears to be a recreation of the novel Jane Eyre and the main protagonist deeply etched in its lines, Wide Sargasso Sea has given its author, Jean Rhys, quite a number of literary distinctions such as the Heinemann Award as well as the coveted W. H. Smith Award, thus securing her a well-deserved spot in the world of the written arts. Although one may be able to observe that, to some interesting degree, Rhys’ novel strongly echoes Jane Eyre in a number of ways and that, hence, her work cannot stand by itself as a lone and solid literary work without depending too much on what has already been written, Wide Sargasso Sea delivers by tempting the mind to look deeper into the context of the story. Not only is one prompted to internalize on the lives of the characters involved and the situations that have kept them both together in a single place and romantically miles apart while living together. The reader is all the more prompted to juxtapose the literary content into the context of the social developments that have shaped the course of the novel. A look into the main characters, Rochester and Antoinette, provides us with a fitting yet succulent glance of the underlying precepts behind the length of the novel. One cannot simply deny and shy away from the fact that, after reading Wide Sargasso Sea, much is to be discerned and contemplated on the behaviors of the characters and the very societal setting that has molded them to what and who they are. Rochester and Antoinette: similarities and differences The characters of both Rochester and Antoinette bear the same characteristic of madness, illustrated to some degree in the former character’s attempt to ditch-off Antoinette by turning towards infidelity and intentionally letting her hear all about his conceited deeds. The fact that Rochester verified the instance when she slept with another woman further illustrate the point that he does not yearn for Antoinette as much as his coldness and arrogance would bitterly consume his outward feelings toward her. Madness has consumed Rochester and his treatment of Antoinette, devouring and distorting his perception of the place where they lived, choosing his England more than anything else whilst staying in a seeming paradise. The madness that has dissolved the humanly precepts of Rochester does not necessarily amount to that of a madman exiled in a sanitarium somewhere in a desolate region. Rather, the context of the madness that have seemed to corrupt his thoughts can all the more me concretized with Rochester’s efforts to keep Antoinette away from him as much as possible, with the very idea that she has turned into a lunatic. Rochester appears to have countered or met the madness in Antoinette by employing actions that can be interpreted as way beyond normal thinking, one that is not commonly done by the normal individual. His deliberate intent of letting Antoinette understand that he has purposely committed infidelity is what a normal person will not usually do, is beyond the point of tolerance, and is exceedingly beyond the limits of a married man. Madness has indeed taken its course in the veins of Rochester as his treatment and attitude towards Antoinette plummet to an unceasingly growing emptiness. Antoinette, on the other hand, has been depicted almost throughout the stretch of the novel as the mad woman that she is, as the Creole taken down by the sheer weight of madness and by the mounting confusion that creases her understanding of her personality and, far more importantly, of her understanding of who she really is. It is not difficult to ascertain from the descriptions of both the personality and actuations of Antoinette that she has been slurred down by the very idea of â€Å"madness† that the people surrounding her have casted upon Rochester’s wife.
