Space Exploration - We Must Explore Mars :: Argumentative Persuasive Essays

Have you ever looked up in the sky and wondered if there is life elsewhere in the universe? Have you ever looked at a photograph of Mars and wondered if there really was ever life on it? People have a wide variety of opinions regarding these questions and with good reason. As far back as the broadcast of H. G. Well's novel, "The War of the Worlds", the world has been fascinated with the possibilities of what Mars may hold. Over time, the majority of people have come to realize that there is no way that life can currently be on Mars. Those who are uncertain think there may be microscopic bacteria underground. There is, however, rising speculation that Mars currently holds ice and possibly flowing water in certain areas on and under the surface. Because of the surface conditions, the water would evaporate very quickly and not be directly visible from space, along with the possible exception of the polar caps, which will be discussed later. Almost all researchers and scientists believe that there is ice on Mars, but the trick is to find it and use it to our benefit. Scientists have dreamt over the possibility that it may be possible to live on another planet. Some think that Mars has that potential to support life, if it's hidden resources are uncovered and exploited to their full potential. There is even evidence that it once contained enough water that it had been possible to hold life. Think about it, what if we could transform it into such a place, even if only our children's children get to see any result? The following will describe Mars, present evidence of ice and water, give possible ideas for the future exploration of Mars, and give reasons for why it is important. The fourth planet from the sun was named after the Roman god of war, Ares and the Greek god of war, Mars. The month of March was named after him so the Romans believed that March was the time of war. Juno, wife of Jupiter, became pregnant with him when Flora, the goddess of flowering and blossoming plants, touched her. Mars was known for his outrage and fury. He is said to have loved battle and killing. He raped a Vestal Virgin, Rhea Silvia. This led to Mars having two sons, Romulus and Remus, who would later found Rome.

The Impact of Advertising on Graffiti

In an era defined by hyper reality, branded lifesylfe, and instant gratification. Effect= noun Is graffiti a direct result of advertising? To evaluate how the advertising industry has played a role in the inception of street art sub culture, we must compare each institution’s role in society, the techniques employed (use of propaganda) by each, and how past artistic movements have been influenced by forces that propel them into. Commercial consumer advertising is propelled by immediate financial profit and mediated by boardrooms and stockholders.It aims at exposing that product in an appealing way, and doing it so as many people are aware of that product. Graffiti is a tool used by individuals with their own agenda, one however that doesn't include profit as its foremost target. The main agenda of a graffiti artist is exposure by means of guerrilla tactics. To understand how advertising has contributed to the establishment of graffiti subculture, the roles each has in society must be examined. Advertising has come a long way from the archaic methods of attraction. Long gone are the times of fact-based advertising.Instead we have moved on to the aesthetisation of commodities, and consequently a world in which the promise made by the seller of love, eternal youth and a perfect body turns people into obsessive-compulsive consumers with a proclivity for instant gratification and a 5-second attention span. The advertising industry sells a way of life, not a product; in fact the ad itself becomes the object of aesthetisation. Over time advertisements have become much more than just ads, they incorporate art of all kinds to appeal to all tastes, using strong cultural signifiers that evoke certain emotions in the viewer.They are like an exact science; they employ psychologists, behaviorists, and all kinds of experts from different fields to pinpoint the moment when a mind will be ready to respond to all these messages. Graffiti becomes a visual manifestation of man's desire to leave his mark on the world, something that is the hallmark of advertising practice, while visually (logos, signs, brands), advertising has provided the ‘raw materials' as it were, with which writers become known. advertising and a world over-saturated with popular culture imagery

Introduction to Organic Chemistry Essay

Amines are compounds composed of nitrogen atoms bearing alkyl or aromatic compounds. Amines undergo interesting reactions, one of which is with the reaction with nitrous acid producing an azo dye. In this study, the experiment focused on synthesizing an observing the physical properties of Sudan-1. Sudan-1 is of the most common dyes found in waxes, oils and in some food ingredients specifically curry and chilli powder. Furthermore, this study aimed to understand the mechanism behind the synthesis of 1-phenylazo-2-naphtol. To be able to synthesize Sudan-1, preparation of phenyldiazonium chloride solution and ÃŽ ²- naphthol solution were done. Ingrain dyeing was also done in this experiment. The synthesis of Sudan-1 has a two-step reaction – diazotization and coupling reactions. Diazotization is the formation of diazonium salt, meanwhile, the coupling reaction took place when an activated aromatic compound, ÃŽ ²-naphtol was reacted with the diazonium salt, benzene diazonium chloride, to form the azo compound known as the 1-phenylazo-2-naphthol. As a result, an orange-red precipitate was formed after series of reaction. Hence, all the said objectives in this experiment were achieved. Amines are compounds that are composed of a nitrogen atom bearing alkyl or aromatic groups. They are basic and nucleophilic because of their lone pair. They occur both in plants and animals. Amines produces some of the most interesting effects and of the common reaction of aminewith nitrous acid producing a dye[4]. Alizarin, for example is a red dye extracted from madder root used by Egyptians and Persians. However, in this experiment, it aimed to produce a dye commonly known as Sudan-1. Sudan-1 is a lysochrome with the chemical formula 1-phenylazo-2-naphthol. It is a powdered substance with an orange-red color. This azo dye is most commonly found in waxes, oils, and also in some food coloring ingredients – curry powder and chili powder. However, the presence of Sudan-1 in most foods now is currently being banned because it has been classified to be carcinogenic. This experiment focused on synthesizing of 1-phenylazo-2-naphthol which is a two-step reaction. The first reaction is the reaction of aniline with nitrous acid, which is called diazotization and second, the reaction of diazonium salt and beta-naphtol to form azo dye which is the coupling reaction. Figure 1 Diazotization Reaction of Aniline to Produce a Diazonium Salt Figure 1 Diazotization Reaction of Aniline to Produce a Diazonium Salt In diazotization reaction, there is a formation of diazonium salts. This reaction is made possible when a primary aromatic amine is treated with nitrous acid. Then in coupling reaction, the electrophilic substitution reaction of a diazonium salt with an activated aromatic ring formed a azo compound specifically an azo dye.[3] The main objective of this study was to be able to synthesize Sudan-1. Also, it aimed to characterize the azo dye with its most distinguishing physical properties. Furthermore, this experiment also aimed to understand the mechanism behind the synthesis of Sudan-1. Figure 2 Coupling Reaction of Benzene Diazonium Chloride with ÃŽ ² -Naphthol Figure 2 Coupling Reaction of Benzene Diazonium Chloride with ÃŽ ² -Naphthol Aniline was reacted NaNO2 crystals under acidic condition using HCl in a cold temperature. The solution was done in a very cold temperature because the phenyldiazonium intermediate easily decomposes back to its aniline counterpart at a slightly high temperature; hence the temperature of the solution was maintained in an ice bath below 5Â °C. Rock salt may also be added to the ice bath to maintain the temperature. However, in this experiment, no rock salts were added instead constant monitoring of the temperature was done. ÃŽ ²-naphthol solution was used as a coupling reagent in synthesizing Sudan-1. In preparing ÃŽ ²-naphthol solution, ÃŽ ²-naphthol was dissolved in 5% of aqueous NaOH and was also cooled in an ice bath below 5Â °C, this was to avoid the decomposition of the compounds. The main reaction that occurred in the preparation of phenyldiazonium chloride solution was diazotization reaction. Diazotization is the reaction between a primary aromatic amine and nitrous acid at cold temperatures to diazonium salt compound.[2] Figure 1 below is the reaction exhibited by the phenyldiazonium chloride solution. As this experiment aimed to synthesize Sudan-1, two steps are done. The first step would be the reaction of a primary aromatic amine to produce a diazonium salt as seen in Figure 1. The second step, then, is the reaction of the diazonium salt with a strongly activated aromatic syste,l known as coupling reactions. Azo coupling is the reaction between a diazonium compound and aniline, phenol or other aromatic compound which produces an azo compound.[5] In this experiment ÃŽ ²-naphthol couples with the diazonium salt. Figure 2 below shows the coupling reaction of the benzene diazonium chloride with ÃŽ ²-naphthol and having the product of Sudan-1. Furthermore, figure 3 below is the summary of reactions of the synthesis of Sudan-1 in this experiment. Figure 3 Summary of Reactions in Synthesizing Sudan-1 Figure 3 Summary of Reactions in Synthesizing Sudan-1 In this experiment, a filter paper was used to undergo ingrain dyeing. Ingrain dyeing is an irreversible chemical reaction of the diazonium salt solution and the activating aromatic solution. An orange-red filter paper was produced after such procedure. The presence of orange-red color in filter indicates the presence of the azo dye (see appendix for the orange-red filter paper produced). The Sudan dye is synthesized right in the spaces between the filter paper such that they are permanently trapped inside the fiber spaces of the filter paper.[2] After mixing the phenyldiazonium chloride solution with the ÃŽ ²-naphthol solution, an orange-red paste-like solution was formed. Furthermore, the mixed solution was also reacted at a temperature not exceeding 4ËšC for 1-5 minutes. Afterwards, the mixture was also filtered was washed with several portions of water to filter the product, Sudan-1. Recrystallization was also done when the filtrate was steamed bath after dissolving it with 95% hot ethanol. AS a result, orange-red crystals were formed which is the Sudan-1 product. The crystal appeared to be orange-red in color due to the N=N bond present in Sudan-1. The N=N is responsible for the absorption of light thus reflecting a color which is orange-red. The structure of Sudan-1 is shown in Figure 4 below showing the N=N bond of the compound. The N=N is known as the chromophores which are responsible for the color. The –OH group attached in the structure is also responsible for enhancing the orange-red color. The –OH functional group is known as the auxochrome, which modifies the ability of the chromophore to absorb the light.[1] Figure 4 Structure of Sudan-1 Azo-compounds, compounds with general formula Ar-N+=N-Ar-, are coupling products from the reaction of diazonium salts with amines. The general reaction pattern for Sudan synthesis first undergoes diazotization reaction and then coupling reaction with highly activated aromatic compounds. In this experiment, the diazotization reaction of aniline with NaNO2 and HCl yielded a diazonium salt, benzene diazonium chloride. Furthermore, the diazonium salt then underwent coupling reactions with an activated aromatic ring which is ÃŽ ²-naphthol. The coupling reaction yielded an azo compound which is most commonly known as the Sudan-1 with an IUPAC name of 1-phenylazo-2-naphthol. As a result of the reactions in this experiment, an orange-red color of solution was produced. This experiment aimed to understand the reactions that underwent to synthesize Sudan-1; as a result, figure 3 was the summary of reactions. As a physical result, orange-red colored crystals were produced representing the azo compound, Sudan-1. However, some minor errors will not be ignored in this experiment. Some errors like human errors might have affected the results in yielding a pure azo compound. One human error, would be the measuring of the reagents used to yield the said product. Also, the misreading of some measurements may have also affected the results of this experiment. Also, some impurities in the chemicals used will also not be ignore, since this impurities may have led to a not so visible side reactions in the said experiment. After being said and done, all the said objectives in this experiment were met.

DECISON MAKING Essay Example | Topics and Well Written Essays - 1000 words

DECISON MAKING - Essay Example The routine decision making can be sub divided into different forms based on several variables that differentiate them; however, the two broad categories of decision making are programmed decisions and non-programmed decisions (O Brien, 1999). A programmed decision is, simply put, a decision that has a fine structure and occurs rather frequently, with less exceptions. Such decisions are relatively easier to make as they follow a pretty standardized procedure; a simple example of the same can be answering a customer query or solving a customer query such as password retrieval. A non-programmed decision is exact complement of the former; non-programmed decisions are more about exceptional handling rather than routine work out, for such decisions, there is less structure of any formal procedures that would resolve the issue. Accordingly, the frequency of occurrence is lesser. Purchase of fixed asset, based on frequency of occurrence can be a non-programmed procedure but since the process of purchase is well defined, it does not qualify for the same. The purchase of a house or a television would be a rather non-programmed decision. In this section, the steps for rational decision making are applied to the given case. ... The case is the need for replacement of the photocopy machine, and the decision making process is to be applied for the purchase of this new equipment (Noorul Haq, 2007). For the decision making process to be successful, it should go by a procedure so that the defined procedure can undertake the different variables needed for an appropriate decision making. Following are the simple steps that are a part of the rational decision making process with brief elaboration (Davidson, 2006), alongside the three steps, their application for the given case is also briefed: STEP I: Recognizing and defining the decision situation: It is essential for managers to recognize and define the need for the decision to be taken. There are certain underlying variables that define the need for the decision; these variables are indicators for the need of a decision. The decision situation has arisen; the photocopy machine needs to be replaced and a new equipment needs to be purchased. The need has arisen mainly due to the excess usage of the equipment in routine business operations. STEP II: Identifying alternatives: Once the need for a decision is identified, alternate decisions available should be identified. Pertinent to this case, the alternatives available are the different models of the machine (that of course have varying functionalities) and the list of pre-selected vendors who sell these machines. Another form of alternative evaluation could have been evaluation of either purchase, rent or not buy at all. However, with the requirements that it caters to, it has become essentially important to buy one as it has a lot of usage in routine operations. Going to a near by shop could have been another way out, which is ruled out due to potential lose out of confidential

Organizational Behavior Essay Example | Topics and Well Written Essays - 500 words - 5

Organizational Behavior - Essay Example According to Kahnweiler (2010),the introvert seeks solitude, thinks first before they speak, focuses on the depth of the problem and prefer writing to talking. They love to manage projects but prefer quiet spaces to do it. They dislike interruptions and they like to finish a project before moving on to a new one. It is noted by the news article that these employees communicate best through relationships and learning to engage them is important as they frequently harbor ideas that will move the team forward. The suggested tactic for dealing with this group of employees is to slow down in meetings, leaving space between directions. This allows this group to think about the issue and respond. Do not stop at their desk frequently. Be aware of what you need to say and bundle it into one visit. Use email or other writing tools to communicate and encourage balanced participation at meetings, allowing introverts to prepare ahead of time. (Kahnweiler, 2010). Sauer, Felsing, & Franke et.al. (2006), describes cognitive diversity and team performance in a diverse organization. As part of the diverse team is the introvert. We often put down the introvert because Freud did not like them and they have been criticized since. Sauer tells us that true to many other researchers, a diverse team is important and that includes the talents of the introvert. Introverts, according to Belleck, (2003) are energized by the internal world of ideas, impressions and emotion. They like to know a lot about what they experience and often build up large stores of knowledge that is often not tapped. This article supports the news article in the need of the introvert to manage projects and to finish a project before they move to a next one, assuring that it is complete. Belleck (2003) finishes her article by stating that a diverse team should include introverts as they are a stabilizing and knowledgeable base for the team as a whole. She goes on to say that provid ing for their communication style

Civil and Construction Engineering, Building Studies and Fire Essay

Civil and Construction Engineering, Building Studies and Fire Engineering - Essay Example National Academy for Professional Training I would like to acknowledge National Academy for Professional Training for providing consultants to assist me in the visit to The Torch Hotel. 1.0 Introduction The topic I have chosen for my final dissertation for Civil and Construction Engineering Building Studies and Fire Engineering is a review of The Torch Hotel in The State of Qatar against the National Fire Protection Association (NFPA) Standards applicable and the standards implemented in The State of Qatar. National Fire Protection Association (NFPA) has been selected as the best practiced standard for my project due to The State of Qatar implementing NFPA as standard requirements for new buildings in The State of Qatar. The Civil Defence Department in The State of Qatar has recently adopted the NFPA standards and based on such my dissertation on The Torch Hotel will identify if the already completed and approved inspection from the Civil Defence meets the standards set forth by NFPA and any other relevant standards applied by the Civil Defence in The State of Qatar. It has been noted that although the local government Civil Defence has adopted NFPA standards for new building requirements, the equipment used by the Civil Defence is based on British Standards and European Standards. Further reviews shall take place during the dissertation on the differences for certain connection requirements on breeching inlets and hydrants. British Standard Connections are different to NFPA standard connections on hose lines. The Civil Defence Introduction The fire service in The State of Qatar is managed by the General Directorate for Civil Defence, a uniformed service organisation under the Ministry of Interior. The General Directorate for the Civil Defence was named as the â€Å"Extinguishing Police Section† during its creation in 1955. Its name was then changed to â€Å"Civil Defence Department† in 1991 and finally to its present name, General Directorate for Civil Defence in 2005. The General Directorate for Civil Defence is generally mandated by law to discharge the following: - Enforcement of Qatar Fire Safety Regulation through the conduct of review and evaluation of building plans and fire safety inspections on all buildings and/or structure prior to issuance of occupancy or renewal permits. - Respond to fire and emergency calls - Promote public fire safety awareness - Review, approval for certification of fire equipment or any other fire safety standards//requirements before they are installed or distributed in the market. 2.0 Background Code Enforcement and Inspection Procedures At present, Qatar has no Fire Code yet being enforced. The GDCD has adopted the National Fire Protection Association (NFPA) Codes and Standards to be its referenced Code/standards in the enforcement of fire safety regulations and practices in Qatar. GDCD on its part has a Fire Safety Standards to supplement the NFPA requirements. The local Fire Safety Sta ndard is somewhat generalized in its form and has deviations or modifications against some sections in the NFPA. These modifications are aimed for the purpose of making some enhancement to suit with the country’s special requirements and added safety as well. In cases where a conflict between the requirements under the NFPA Code/Standards and local fire safety standard occurs, the requirements from the latter must prevail and should be followed. Building Plan Review and Evaluation The
