Additionally, it was create two-dimensional structure chromatogram, which is the proof of assistance in the composite class. Samples can often be minimized or even eliminated in some cases for the practice, as technology provides excellent separation power. All these benefits make GCÃâ€"GC in the toxic compounds involved in the determination of trace level environmental analysis of a very good tool in complex matrices. This paper summarizes some of the environmental analysis and review and monitoring of the GCÃâ€"GC applications Introduction Many years of humans society development led to many of the world distribution of chemicals in the atmosphere, the Earths surface and land border. Many of these compounds are harmful to the worlds ecosystems and the people. Analysis of these compounds in the environment is important. When analytes have high vapor pressure, gas chromatography is the selection method. The main problem in the environmental analysis is to analyze the existence of material is usually very complex matrix trace. Result, a huge research work into the analysis of major environmental pollutants [1]. Methods used in environmental analysis is usually the same as in all aspects of practice. It includes sampling, sample preparation, separation and detection. All of these steps may benefit from change, it is usually the biggest limitations imposed by the separation step. In gas chromatography (GC) cases, the majority of environmental samples containing analyte and matrix components of many closely eluting peaks in a chromatographic dimension (1D) the maximum total capacity is greatly exceeded, and many coelutions and unresolved in the separation region was observed. This led to the analyte of interest and quantify the poor separation [1]. Poor resolution in the chromatographic analysis of sample preparation and detection of high demand for equipment placement. Expensive and labor-intensive sample preparation, and solvent waste may cause a lot of harmful to the environment.   By microextraction method development, such as liquid-liquid microextraction (LLME) and solid phase microextraction (SPME) and non-dissolved sample introduction system (ie, direct thermal desorption), has the potential to greatly simplify the sample preparation process, without sacrificing sensitivity and selectivity [2-5]. On investigation, lack of resolution often means using mass spectrometry (MS), including high-resolution mass spectrometry (HRMS), in some cases, is necessary. Figure 1 illustrates the GC-MS encountered in the common problems [36]. In the analysis of food extracts commonly 1D-GC clinch with insecticides (Fig. 1b), trace interest (in this case chlorfenvinphos) coelute analyte and sample matrix is ​​more abundant components. Results obtained for such compounds, mass spectrometry (Figure 1e) frequently contains compounds derived from fragments of interference, leading to poor matching and library mass spectrometry (Fig. 1d). MS overlap algorithm may greatly improve the quality of the information of coeluting peak, but they are not always successful, when the number of coelutions is high. Figure 1a shows, full 2D-GC (GCÃâ€"GC) to increase space and improve the chromatographic separation of the resolution, resulting in the separation of analytes of interest (chlorfenvinphos) from coeluting compounds and matrix components. Result, improved the quality of the analyte mass (Fig. 1c), taking into account the proof of a more confident analysis of material (Figure 1d). It is possible that some coelutions exist; these may often solve efficiently overlap with the MS, leading to better results, while reducing the number of components when the coeluting. GCÃâ€"GC separation with the increased power res ulting in a successful demonstration and quantification of analytes. Fig. 1 GCÃâ€"GC–TOF MS versus 1D-GC–TOF MS for the analysis of a carrot extract. The highest-capacity problem in terms of conventional gas chromatography through multi-dimensional gas chromatography to cope (MDGC) implementation. In this method, one-dimensional (1D) chromatogram of a complex and unresolved part is subjected to the stationary phase coated with a second column separation of the other selectivity [1]. Although this method increases the 1D chromatographic part of the choice of chromatographic resolutions, this method with automation challenging, and only a few sample components can be adequately addressed. However, the many applications is good for the PCBs, pesticides and toxaphene analysis, among other things, the report with different degrees of success [6-12]. Overall, however, is the exact number of separation will be beneficial, if the entire sample is subjected to a separation in two dimensions. This became possible a comprehensive two-dimensional gas chromatography (GCÃâ€"GC) in the introduction. Principle for Two-Dimensional Gas Chromatography (GCÃâ€"GC) 2D-GC is a comprehensive method of fundamental solution to meet the highest capacity. A typical structure of GCÃâ€"GC set in Figure 2. The basic structure of GCÃâ€"GC using virtually is the same as the composition of 1D-GC. These include syringes, oven, columns and detectors. In a typical GCÃâ€"GC system, using non-polar stationary phase coated with a thick coating of a long column was installed as the main column. The exports through a special interface or modem is connected to the entrance of the second dimension column coated with stationary phase of another selectivity. Modulator connected not only to primary and secondary column; its main role is repeated trapping of the effluent fractions from the first dimension and periodic injection of them to the form of narrow pulses separated into further chromatographic analysis. Because the operation of 2D-GC in the fast condition, the detector in the GCÃâ€"GC selection is limited to those capable of fast data collection rate. For e xample, GCÃâ€"GC detector can include flame ionization detector (FID), electron capture detector (ECD), single atomic emission detector (AED), sulfur compounds optical detector (SCD), nitrogen photodetector compounds (NCD) and time of flight mass spectrometer (TOF MS). Fig. 2 A block diagram of a GCÃâ€"GC system. Modulator is the important part of the instrument, because it guarantees the separation is comprehensive and multidimensional [13]. In 1991, the first implementation of the GCÃâ€"GC, the field has witnessed a number of modulator design [14]. Initially, the use of thermal adjustment of the heat modulator was implemented; however, the modular cryogenic liquid (liquid carbon dioxide or nitrogen) is currently the main use. Modulator at low temperatures within the system, each design has its own distinct advantages and limitations, making it suitable for analysis of the specific type. For example, the analysis of water pollutants has been developed an interface [19], when the buildings, and an in-house applications modulator in the quantitative analysis of PAHs and PCBs has been described [15]. Then, the modulator of the different types of analyte in the analysis of organohalogenated been evaluated [16]. The implementation of GCÃâ€"GC provides the following advantage to surpass the 1D separation method: improvement separation strength; improved sensitivities; and constructs or highly predetermined, stratography spectrum. In the environment analysis, GCÃâ€"GC has the potential to improve the toxic compound through the separation from the coeluting analysis and the matrix component, increases the detection limit such chemical product and provides the ideal for the surveillance application the two-dimensional stratography spectrum which constructs. Finally, this possibly causes to reduce to the smallest sample preparation procedure, and reduces analysis time. Other applications are also possible. For example, recently, GCÃâ€"GC the product estimate which divided into for the diesel oil hydrocarbon environment had used, was important affected many ecosystems [17] the oil leak. Application of GCÃâ€"GC in Environmental Analysis Water and Sediment Analysis The water is the most basic material to the life in planet. In order to estimate that the tap water safety for human consumption, the rapid, precise and the accurate method needs to analysis the water. The sediment is also important for river and the lake; The analysis of water pollutant is time-consuming sample preparation, follows by GC-MS analyzes. In the initial period realized that GCÃâ€"GC has the great potential improvement to analysis water and sediment. In its earliest applications in this region, GCÃâ€"GC was explained possibly from the common matrix interference which is separating the BTEX (benzene, toluene, ethyl benzene and xylene) and methyl alcohol tert butyl ether (MTBE), when and SPME [18]. The separation strength of GCÃâ€"GC is improved; MTBE and the benzene are the foundation line solution in the 2nd chromatograph analysis space. This research showed GCÃâ€"GC has the great potential for water   pollutant analysis by combination this technology with microextraction (head space SPME). Certain Earths freshwater body is polluted daily by petroleum and the oil contamination. In the 1970s, it is pays attention the petroleum sample stratography spectrum to exhibit a model, has not solved, foundation line which rises â€Å"hillock† [20]. Chromatogram is the complex part, including compound many different kinds, refers to â€Å"unsolution complex mixture† at present [21]. GCÃâ€"GC-FID uses in analysis of two different freshwater sediments [21]. Observed the conventional sample preparation procedure, the author has used the superior resolution, and has constructed the chromatogram of sediment for UCM different levele by GCÃâ€"GC. The chromatogram obtained for two samples provides by clue direction contamination important source researcher. , The research showed GCÃâ€"GC the potential importantly in the environment law, for an environmental chemistry basic tool, environmental audit. The nonylphenol polyethylene ethoxides degenerated product, was possible feminine hormone splitter [22]. Increases the concern, NPs from the urban district [23] the water and the deposition present are found. GCÃâ€"GC-TOF MS is the NP isomer separation from technical mixture [24] used. 41 components are identified. Figure 3 explanation GCÃâ€"GC-TOF MS application to NP isomer respective ion trace analysis from identical research. Two NP stave products were explained that m/z 135 (chart 3a) and m/z 149 (chart 3b). Two chromatogram exhibition group type separation, emphasizes by the connection compound peak maximum value in the identical homologous family incline line. It from as a result of various NP isomer structure similarity, the complete separation is the very difficult this chart is obvious. However, other resolution strength by GCÃâ€"GC provided â€Å"cleanly† the mass spectrum to provide, made the analysis proof to be easier. Fig. 3. Extracted ion GCÃâ€"GC–TOF MS chromatograms of a technical nonylphenyl (NP) mixture GCÃâ€"GC for to the environment pollutants analysis was recently the application current in oceanic deposit [25]. A qualitative method has developed, fast and is unified according to the tendency by the ultrasonic wave assistances extraction to the complex samples high resolution analysis provides to GCÃâ€"GC-TOF UAE which is fast and high efficiency selective sampling pretreatment procedure is utilized solid sample [30]. A high efficiency and has the selective sample preparation method, when the powerful separation method GCÃâ€"GC combine with UAE can causes 1500 kind of more than several not aromatic hydrocarbon (PAHs) the compound and the certificate resolution, NPs and dialkylated benzene. Once more, GCÃâ€"GC not only ability from each other isolation analysis, and has proven from the sample matrix priceless. The carcinogen which and the mutagen suspected, PAHs is many industry activity by-product and the universal existence is distributed in the environment. Because it requests the hard sledding and has the selective sample preparation, they in the deposition samples trace determination are difficult. The improvement to complex matrixs PAHs, the Cavagnino trace analysis with GCÃâ€"GC-FID [large-volume splitless injection (LVSI) technology]. Sample complex which analyzes is many deposition sample representative who obtains from the river and the lake. Separated and investigates seven PAHs which diluted in the synthesis diesel oil to demonstrate the LVSI- GCÃâ€"GC-FID potential achievement in the low ppb level for to trace amount analysis one powerful and the rapid tool in complex matrix PAHs. While, Ong. and so on has developed a PAHs rapid surveillance method probably in the soil sample, utilizes liquid extraction (PLE) GCÃâ€"GC-FID [27]. The current publishing work is merely GCÃâ€"GC latent serviceable demonstration to deposition sample PAH analysis. In brief, with the resolution which improves, improvement many sensitivities and the stratography spectrum which orders, GCÃâ€"GC may add on the result which effective and the rapid sample preparation method produces cannot be achieved by the routine analysis procedure. Analysis of PCBs, PCDDs and PCDFs Polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and some polychlorinated biphenyl (PCB) congeners is dominated by bioaccumulation and biomagnification in the environment and thus is a dangerous The wildlife and people. Many are suspected carcinogens and induced changes of [28]. Of PCBs, dioxins and furans in the environment assessment of certain requirements of a method to isolate and quantify them in complex samples such as food, soil and water. GCÃâ€"GC provides one advantageous method in complex matrixs PCDDs and the PCDFs analysis. In its one of early experiments, a liquid crystal main column and a limitless secondary column (according to steam pressure separation) uses in (according to the planarity separation) separates the tone and from technical mixture [30] non-straight PCB congeners. The connection GCÃâ€"GC microelectron captures investigates (MECD) is toxic PCBs, PCDDs and the PCDFs determination is the application in the cod liver sample [29]. The analysis result showed all 12 priority PCB from liver sample congeners, and most toxic Dai Aoxin and fu nan the full separation and the proof nail fast with 90 PCBs and 17 contain poison PCDDs and PCDFs. Moreover, when compares with the standard sample preparation procedure, the liver sample pretreatment does not have the selectivity and reduces to is smallest. It has included the direct injection and fractionation followed cell degree of illness gradually draws back, the centrifuge process to enter GCÃâ€"GC the system. Figure 4 showing from the 2nd stratography spectrum which obtains to the cod liver samples analysis. Recently, an item of multilaboratory research has been conducted in food sample, analyzes PCDD/Fs and World Health Organization PCBs through once more GCÃâ€"GC-MECD and the GC-HRMS comparison and the explanation GCÃâ€"GC great potential in the rapid surveillance application [31]. With the standard analysis method comparison GCÃâ€"GC, GCÃâ€"GC the performance is unified (GCÃâ€"GC-ID-TOF MS) has to 13C mark isotopic dilution (ID) TOF MS conventional GC-HRMS to appraise [32]. Quantification 17 PCDD/Fs and four PCBs nail fast in the soil and in the deposition sample are two methods are comparable. However, GCÃâ€"GC implementation request only smallest sample preparation, and causes the signal improvement (factor 5-10), superior resolution, lower instrumentation expense, and improved TOF the MS data [32] the ghost overlaps legitimately. As highest capacity which and resolution result increases, the unknown compounds proof is possible. Fig. 4 GCÃâ€"GC–ECD chromatogram of a cod liver sample spiked with 90 PCBs [29]. Pesticide Analysis Forms the challenge to the pesticide analysis to analyze the chemist to prepare about the sample to make the law and the chromatography. Is similar other toxic compound, the pesticide is usually distributed in the trace amount environment. Moreover, they are extreme complex matrix part of for example foods, the soil and the water sample. Needs to be like today presses to the rapid high resolution analysis method. GCÃâ€"GC the application early showed the method potential regular implementation to the pesticide analysis in persons organization in the future. Supercritical invariable extraction (SFE) with GCÃâ€"GC-FID together utilizes the analysis in persons blood serum [33] the pesticide. To were few from the sharp persons blood serum extractions 15 pesticides foundation line segments achieve in four minutes. Later, GCÃâ€"GC-FID to estimate that the child pesticide exposure has been utilized through the use urine and the blood serum [34] low-power. This special example in were few showed 16 pesticide complete separations in four minutes. Recently, has been demonstrated including PCBs and the organic chlorine pesticide 59 organization pollutants proof and the quantification [35]. But GCÃâ€"GC-ID-TOF MS completed the comparable result author who ran in standard routine analysis (GC-ID-TOFMS) to indicate that analyzed like this, three different injection needs. GCÃâ€"GC the application earl y showed the method potential regular implementation to the pesticide analysis in persons organization in the future. Supercritical invariable extraction (SFE) with GCÃâ€"GC-FID together utilizes the analysis in persons blood serum [33]. Pesticide determination in food extract is similarly important. Separated using GCÃâ€"GC-TOF MS and identifies 58 pesticides to nail fast completely on the vegetable was explained [36]. This completed with has been smallest and the non-selective sample preparation: The celery or the carrot sample and the sodium acetate and the ethyl acetate have chopped, mixed, was mixed, has been separated, and is dried. The extract is injected entered GCÃâ€"GC [36]. Recently, separated 12 halogenate compound kind of groups five different GCÃâ€"GC column combination to appraise, including PCBs, PCDDs, PCDFs, multi-chlorobenzene diphenyl ester (PCDEs), multi-chlorobenzene naphthalene (PCNs), multi-chlorobenzene dibenzothiophenes (PCDTs), multi-chlorobenzene terphenyl (PCTs), multi-chlorobenzene alkane (PCAs), toxaphene, multi-bromination biphenyl (PBBs), multi-bromination diphenyl ether (PBDEs) and organic chlorine pesticide (OCPs) [37]. Although this article focal point is the different compound kind of major group separates, was also explained in the family separation. When the separation and proof all 28 OCPs are pure pesticide mixture has only been demonstrated that majority has been separated fully, since, when injects along other 11 compound kind of [37]. Therefore, its as if that the column establishment which disposes appropriately with one, GCÃâ€"GC may use takes mainly shields step for the environment sample contamination and along pol lutant many other kind of pesticides, with smallest sample preparation. Air Analysis Volatile organic compound (VOCs) in metropolis photochemical smog [38] the generation plays a strong character. The World Health Organization thought that possibly has to the air granular materials exposition to the human health [39] the ill effect. But, uncertainty existence about from VOCs health effect in metropolis granular material (PM) [40]. Therefore, requests rapid, reliable and information method guarantee in air pollutant successful surveillance, proof and discovery. Many PAHs and PAHs (oxy-PAHs) which oxidizes is the carcinogen which and the mutagen suspected, with, therefore they are in the metropolis aerosol analysis profitable target analysis. GCÃâ€"GC-FID and GCÃâ€"GC four-pole MS (QMS) is applied permits from Finland about 1500 peaks goal PAHs [41] investigates in the metropolis air sample and the proof. But woman is unified the method for the compound proof and the quantification, used GCÃâ€"GC-FID the combination to confirm the good reproducibility. 13 non-goal PAHs has been identified, and ten goal PAHs by quota. Found PAH centralism scope (0.5-5.5 ng/m3) with in Europe [41] other parts of standard methods obtained the result was comparable. The cigarette smoke is estimate extreme complex mixture component [43] which has not recognized including about 4,700 kind of identifications compound and 100,000. GCÃâ€"GC-TOFMS utilizes the solution approximately from the cigarette smoke [43] 30,000 peaks. After this, analyzes cigarette smoke condensate simpler sample determination neutrality score [44], basic score [45] and acidic score [46] chemical composition. Conventional GC-MS possible to separate 200 unknown peaks and identifies 115 hydrocarbons from the cigarette condensate limitless neutral scores; To identical sample GCÃâ€"GC analysis, however, has achieved 4,000 kind of compound separations and 1,800 hydrocarbons [44] proved. In another research, GCÃâ€"GC-TOF has identified 377 kind of nitrogen-containing compound to the cigarette condensates basic scores MS analysis, in 155 is the pyridine derivative, 104 kinds kui lin or different kui lin derivative and 56 kind of pyrazine derivative [45]. Conclusions GCÃâ€"GC has achieved the condition rapidly for to the volatile organic compound analysis most powerful tool. It appoints oneself achievement to be suitable completely for in the complex sample surveillance analysis technology. In the environment analyzed area, this includes PCBs by the analysis many example testimony to the common environment pollutant, PCDDs, PCDFs, PAHs and the pesticide in the complex environment matrix. Moreover, GCÃâ€"GC has the potential to simplify the sample preparation procedure (even completely to eliminate them), when simultaneously causes when the shorter overall analysis time high resolution stratography spectrum. Regarding widely a new analysis method which adopts, not only it is certainly reliable and renewable, but it should also exhibit the significant advantage to surpass the method which accepts. The example reported the showing GCÃâ€"GC method advantage in this review in the traditional 1DGC separation. In GCÃâ€"GC historical first years period, the instrumentation development is the main focal point; However, from GCÃâ€"GC systems commercialization, the application quantity which reported greatly increases in the environment analysis and other scientific fields. Therefore, we may anticipate that the transition automation GCÃâ€"GC is unified on-line sample which the correspondence uses to prepare gradually the equipment in the regular environmental monitoring.

Essay Competing Value Framework - Research Paper Example It also helps in improvement of the profit margin and revenue of the organization as compared to other rivals in the market. Other than this, the framework of CVF is also often thought to be as a leadership tool utilized to improve the sales and revenue of the organization. Moreover the CVF might also be used for varied aspects and levels in organizations for their betterment and improvement. Apart from this, the CVF also serves as a map, an organizing mechanism, a sense-making device, a source of new ideas and a learning system to make the organization more and more effective in long run. This research paper mainly describes the meaning and developments of competing value framework (CVF) and the organizational focus with the help of two axis’s long with its benefits for the organization Definition of competing value framework Competing Values is all about accepting and analyzing the ways to appreciate the conflicting values in order to integrate them successfully for the bett erment of the organization. This might help the organization to improve its total sale as well as brand image in the market among others in the market. Along with this, it might also help an organization to analyze the strength and weakness so as to make use of it for its improvement and reduce its discrepancies. The Competing Values Framework (CVF) was developed for the benefit of the organization by analyzing the organizational culture, organizational effectiveness, organizational design, information processing, organizational quality, leadership competencies, stages of life cycle development, leadership roles, financial strategy and brain functioning. Therefore after examining all these above mentioned factors, the effectives of the organization may be improved as compared to others (Smart & Hamm, 1993). Other than this, if the organizational profit margin is increased then the level of reliability and trust of the customers over the brand might also increase resulting in amplifi cation of its total customers range. Due to all these advantages, it is considered to be one of the best models to improve the organizational portfolio in the market among others. Consequently it also helps to identify the set of guidelines that might facilitate the managers or leaders to diagnose, congruencies, manage the interrelationships and contradictions among the different aspects of associations to improve the organizations’ performance and market value in the market. So, it is highly appreciated (Quinn & Cameron, 1999). Development of competing value framework The Competing Values Framework came into existence from a series of theoretical framework and empirical studies and research conducted on the idea of organizational efficiency (Quinn & Rohrbaugh, 1983). All these efforts are performed with an attempt to improve the essence of organizational effectiveness in the market (Quinn and Rohrbaugh, 1983). Apart from this, the faculties of University of Michigan also und ertook varied types of organizational aspects into consideration so as to improve the fame in the market among other rivals. It consists of two dimensions among which the first one is related to organizational focus on the internal emphasis of the employees of the organization along with the external factors as well. The second dimension represents the contrast

Legalizing marijuana Essay Example | Topics and Well Written Essays - 250 words - 1

Legalizing marijuana - Essay Example Yes, marijuana can make you crazy so legalizing it is wrong. We can cite the country of Jamaica, one of the largest producer of marijuana in the developing world where marijuana is very common. And if we think that authorities approve marijuana there, you are very wrong. Marijuana is one of the main culprit of the countless number of adolescents who committed petty crimes having police records early (Campbell, 2013). Marijuana makes a youngster susceptible to crime because it impairs one’s judgment. Or in short, you cannot think straight when you are in the influence of cannabis. Worst, if you like it too much and you do not have money to buy it because you are only a student, you will either sell things or steal. And worst, if police catches you, you will end up in jail and have police record early affecting your future because it will be hard to find a job if one has a police record. School will also likely to kick you out if you have a criminal record for stealing because of marijuana. Campbell, Dayton.

Should the Government Intervene in the labour market Essay

Should the Government Intervene in the labour market - Essay Example Various critics argue that the government involvement in the labor markets is significant since it promotes free and fair employment while other argue the exact opposite, citing that in hinders the willing employer, willing employee relationships, owing to the various policies implemented (Tisdell and Hartley, 2008 p.269). Government involvement in the labor market is critical since it acts in response to various challenges that emerge in employment. For instance, employers may opt to hire employees at extremely reduced rates, owing to their intended purpose of maximizing their profits. At such instances, some employees may be willing to work with such wages, owing to the unemployment rates resulting from economic recession globally while other suitable employees may be unwilling to work under such rates. This creates a challenge since the unemployed individuals may act in their fight for increased pay, which may lead to property and life destruction, and this call for government involvement, in a bid to provide a solution to such a predicament through the introduction of the minimum wage policies. In other instances, some unscrupulous employers may overwork their employees without increasing their minimum salaries, and even subject them to working under harsh and dangerous conditions without the implementation of the necessary safety measure policies, in their bid to reduce costs(Neugart, 2002, p.69). This places the employees’ welfare at risk, and cases of employee opposition have been rampant across the globe. As such, government intervention is critical in such institutions since the government is tasked with the provision of apt safety policies that safeguard the welfare of such employees. This serves to reduce the employer-employee conflicts hence promoting production and profit maximization of such firms. Additionally, cases of employment of minors are still in practice,

Meditation Essay Example for Free

Meditation Essay Meditation Sit as you wish on a chair or on the floor with your back straight. Turn the palms of your hands up Close your eyes. Take a deep breath, inhaling through your nose and exhaling from your mouth. With each breath, in and out, release the tension in your body more and more. Smile, and imagine each organ in your body, in turn, smiling back at you. Think of what you have to be grateful for in your life. Now start visualizing a fluid white light entering your body through your feet and moving slowly pward, toes to feet to ankles, legs to thighs and hips saying to yourself I open myself to the light, to the teacher within and without or I honor the divinity that resides within me. Continue to visualize the light rising, filling every inch, every muscle- hips to waist, belly, back, shoulders lingering everywhere you feel tension or pain -your arms, elbows, hands and fingers. Feel the light move up, neck to chin, to lips, eyes, forehead and hair. Now see how your entire body glows with white light. See a spark of that light leave your body through the top of your head. You are that spark of light. See that spark of light you flying high to the sky, to the clouds. Repeat I open myself to the light, to the teacher within and without or I honor the divinity that resides within me. Continue to fly, higher and higher, until you are in a magical place, unseen before, a place of beauty almost beyond imagining. Colors so vibrant they seem unreal, lakes, mountains, waterfalls, flowers, birds and butterflies and unicorns, fanciful creatures of all kinds. Create your imaginary garden, your magical place you will always go to. Here everything is peaceful, and everything possible. When a thought comes to mind Just focus on your breath or repeat and let the thought go like clouds in the sky. Be gentle with yourself. Imagine now a bright white light shining down upon you, reflecting and intensifying your own light giving you unconditional love. Love as you have never known it before. Rest in this place. Rest here, and magic will happen. When it feels right, begin the return to your body n the same way you left it slowly, until you are ready to end your meditation. But before you end it, visualize your body filled with light, enter it and stay with for a few minutes. Then, with your hands in prayer position, lift them to your forehead to remind yourself to be aware of your thoughts. Drop them to your lips to remind yourself to be conscious of your words. Drop them to your heart to remind yourself to be conscious of your actions. And last, bow to yourself to honor the master within you You are saluting the God By satharmk

An Analysis of The Cask of Amontillado Essay -- essays research papers

An Analysis of â€Å"The Cask of Amontillado   Ã‚  Ã‚  Ã‚  Ã‚  In â€Å"The Cask of Amontillado† Edgar Allan Poe takes us on a journey into the mind of a mad man. The story relates a horrible revenge made even more horrible by the fact that the vengeance is being taken when no real offense had been given. In a short space and with ultimate technical skill, Poe creates a nightmare, guaranteed to give the reader a sleepless night.   Ã‚  Ã‚  Ã‚  Ã‚  The plot of the story is a simple one. Montresor tales revenge on his friend Fortunato by luring him into the tunnels under the family estate. There he leads Fortunato into the depths of the catacombs where he buries him alive by walling him into a niche. The story is told in first person from the point of view of Montresor himself. The exposition of the story occurs when Montresor tells us that he wants to take revenge on Fortunato because â€Å"he ventured upon insult.† We also learn that he intends to go unpunished for this act of vengeance. The narrator informs us that he is going to continue to smile in Fortunato’s face, but use the pride his victim has in wine to lure him into the catacombs to taste some of his non- existent amontillado. At this point, the reader knows the conflict will be one of man against man. It is an external struggle because Fortunato and Montresor are in a life and death fight. However, the conflict is largely internal, because Montresor has a fierce hatred that Fortunato is unaware of. The narrative hook seems to occur when Fortunato follows Montresor into the vault. Even if the reader was confused by the language of the first paragraph or is puzzled by the motive of the narrator, he is curious to know what will happen next. We know the moment of revenge is at hand, but what is Montresor going to do to Fortunato? Why is he taking him underground?   Ã‚  Ã‚  Ã‚  Ã‚  The climax of the story is when Montresor chains Fortunato to the wall and begins to layer the bricks. It is our high point of emotional involvement. We are like Fortunato in that we cannot bring ourselves to believe what is about to happen. The denouement lets us know indeed, Montresor was never punished for this crime. Fifty years has passed and he is an old man telling the story on his deathbed. The true horror is that Fortunato died a terrible death, utterly alone, and his killer was never brought to justice.   Ã‚  Ã‚  Ã‚  Ã‚  Perhaps the theme in the story is the least imp... ...ng about Fortunato’s health and says he will not die of a cold. The greatest use of irony is when Montresor says he is a member of the masons. Fortunato thinks he means he is of a fellow member of a society when what he really means is that he is a bricklayer about to brick him in for all eternity. This conversation also provides foreshadowing in the story. This is the first clue the reader gets about how Montresor will punish Fortunato.   Ã‚  Ã‚  Ã‚  Ã‚  The overall mood of the story is one of horror and impending evil. The ending of the story is filled with suspense. What will happen now that Fortunato is chained to the wall? Will Montresor come to his senses and have mercy on Fortunato? We see Montresor carefully construct each tier of the wall. Why does he hesitate at the end? Will he react to the desperate cry of Fortunato? When the last brick is set in place, we know Fortunato’s doom has been sealed.   Ã‚  Ã‚  Ã‚  Ã‚  I find that this story makes the hairs on my back of my neck rise every time I read it. There is no real violence in the modern sense of the word, yet it is more horrifying because of all the things you don’t see with your outward eye but the with inward eye of the imagination.

The Scholarship Management and Accounting Reports for Tenpins (SMART) program will help locate and secure existing bowling scholarships for YABA's membership. SMART will also help any organization start and manage a new bowling scholarship program while relieving new and existing bowling scholarship providers from the burden of administering their scholarship funds. YABA has developed two service levels to accomplish this mission: Level one is SMART's information and assistance level. This SMART level can be contacted in one of three ways – telephone, mail or email. SMART Level One will provide the following services: Information on how to start a bowling scholarship league, tournament or written Information on how to manage the scholarship dollars collected. Advise, assist and support organizations regarding any problem encountered in conducting or administering their scholarship programs. A booklet containing location of scholarship leagues, tournaments, and written cholarships offered worldwide; universities and colleges that offer bowling scholarships and those offering bowling as a scholastic or club sport; and national scholarship applications. In Level Two, the organization forwards their scholarship dollars to SMART, and SMART will manage their scholarship dollar on a daily basis. SMART charges no fee to use the program. SMART operates off the interest made on the scholarship funds. At the end of each bowling season (July 31st) SMART will deduct the operating expenses from the total interest earned. The remaining interest will be credited to each organization. The amount each organization receives will be determined on a percentage basis by the total amount of scholarship funds in their account. The organization then may use the interest as new scholarships at their discretion. For more SMART information, write to SMART 5301 S. 76th St. , Greendale, WI 53129, call 414/423-3343, fax 414/421-3014 or e-mail Ed Gocha at [email  protected] com. 999 Youth and Collegiate Bowlers Scholarships SMART's 1998 Youth and Collegiate Bowling Educational Guide is provided here for Junior Olympics Program To help young bowlers progress from their first visit to a center o becoming a Junior Olympic Gold member, YABA has created a pipeline (to be released in July 1999), to guide them through the different stages of development and prepare them for active roles as participants in the adult membership With this road map, youth bowlers will be guided through five different levels of bowling; Introduction to Bowling, First Organized Program, League Participation and Introduction to Tournament Competition, Purely Competitive and Elite Competition (TEAM USA).
