Camel Facts

Camel Facts Camels are mammals known for their distinctive humped backs. Bactrian camels (Camelus bactrianus) have two humps, while dromedary camels (Camelus dromedarius) have one. These creatures humps store fat deposits that they use as sustenance when external food and water sources are scarce. Their ability to metabolize stored food for prolonged periods of time makes them good pack animals. Fast Facts: Camel Scientific Name: CamelusCommon Name: CamelBasic Animal Group: MammalsSize: 6–7 feet in heightWeight: 800–2,300 poundsLife Span: 15–50 yearsDiet: HerbivoreHabitat: Deserts in Central Asia (Bactrian) and North Africa and the Middle East (Dromedary)Population: 2 million domesticated Bactrian camels, 15 million domesticated dromedary camels, and less than 1,000 wild Bactrian camelsConservation Status: The wild Bactrian camel is classified as Critically Endangered. Other camel species are not considered endangered. Description Camels are well-known for their distinctive humps, but they also have other distinctive characteristics that make them well-suited for living in desert conditions. Importantly, camels have the ability to close their nostrils to prevent sand infiltration. They also have two rows of long lashes and a third eyelid. Both structures help to protect their eyes in harsh environments such as sandstorms. They also have thick hair that helps to protect them from the intense sunshine in their environment as well as padded feet to help withstand the hot temperatures of the desert floor. They are even-toed ungulates (hoofed mammals). Two-humped Camel.   Elena Kholopova/EyeEm/Getty Images Camels are usually between 6 and 7 feet in height and 9 to 11 feet in length. They can weigh up to 2,300 pounds. Other physical characteristics of camels include long legs, long necks, and a protruding snout with big lips. Habitat and Distribution Bactrian camels live in Central Asia, while dromedary camels live in North Africa and the Middle East. Wild bactrian camels live in south Mongolia and northern China. They are all typically found in desert regions, although they may also live in other similar environments like prairies. While we associate camels with extremely hot temperature environments, their habitat can also include extremely low temperature environments. They form a protective coat in the winter to help with the cold and shed the coat in the summer months. Diet and Behavior Camels are diurnal creatures, which means they are active during the day. They subsist on vegetation like low-lying grasses and other thorny and salty plants. To reach such low-lying plants and grasses, camels have developed a split upper lip structure so that each half of their upper lip can move independently, which helps them eat low-lying plants and grasses. Similar to cows, camels regurgitate food from their stomach back up to their mouths so they can chew it again. Camels can hydrate themselves faster than other mammals. They have been purported to drink approximately 30 gallons of water in a little over 10 minutes. Reproduction and Offspring Camels travel in herds made up of one dominant male and a number of females. A male bulls peak fertility, called rut, occurs at various times during the year based on species. Bactrians fertility peak occurs from November through May, while dromedaries can peak throughout the year. Males will usually mate with half a dozen or so females, although some males can mate with over 50 females in one season. Female camels have a gestation period of 12 to 14 months. When it is time to give birth, the expectant mother typically separates from the main herd. Newborn calves can walk shortly after birth, and after a period of a few weeks alone, the mother and calf rejoin the larger herd. Single births are most common, but twin camel births have been reported. Threats The wild Bactrian camel is threatened mainly by illegal hunting and poaching. Predator attacks as well as mating with domesticated Bactrian camels are also threats to the wild Bactrian camel population. Conservation Status Wild Bactrian camels (Camelus ferus) are designated as critically endangered by the IUCN. Fewer than 1,000 animals are left in the wild with a decreasing population. By comparison, there are an estimated 2 million domesticated Bactrian camels. Species There are two main species of camel: Camelus bactrianus and Camelus dromedarius. C. bactrianus have two humps, while C. dromedarius have one. A third species, Camelus ferus, is closely related to C. bactrianus but lives in the wild. Camels and Humans Humans and camels have a long history together. Camels have been used as pack animals for centuries and were likely domesticated in the Arabian peninsula between 3000 and 2500 BC. Due to their unique features that allow them to withstand desert travel, camels helped to facilitate trade.

The Scales of Atmospheric Motion

The Scales of Atmospheric Motion The atmosphere is always in motion. Each of its swirls and circulations is known to us by name- a gust of wind, a thunderstorm, or a hurricane- but those names tell us nothing about its size. For that, we have weather scales. Weather scales group weather phenomena according to their size (the horizontal distance they span) and how long of a lifespan they have. In order from largest to smallest, these scales include the planetary, synoptic, and mesoscale. Planetary Scale Weather Planetary or global scale weather features are the largest and longest-lived. As their name suggests, they generally span tens of thousands of kilometers in size, extending from one end of the globe to another. They last weeks or longer. Examples of planetary-scale phenomena include: Semi-permanent pressure centers (the Aleutian Low, Bermuda High, Polar Vortex)The westerlies and trade winds Synoptic or Large Scale Weather Spanning somewhat smaller, yet large distances of a few hundred to several thousand kilometers, are synoptic scale weather systems. Synoptic scale weather features include those having lifetimes of a few days to a week or more, such as: Air massesHigh pressure systemsLow pressure systemsMid-latitude and extratropical cyclones (cyclones that occur outside of the tropics)Tropical cyclones, hurricanes, typhoons. Derived from the Greek word which means seen together, synoptic can also mean an overall view. Synoptic meteorology, then, deals with viewing a variety of large scale weather variables over a wide area at a common time. Doing this gives you a comprehensive and nearly instantaneous picture of the state of the atmosphere. If youre thinking this sounds an awful lot like a weather map, youre right! Weather maps are synoptic. Synoptic meteorology uses weather maps to analyze and predict large-scale weather patterns. So each time you watch your local weather forecast, you are seeing synoptic scale meteorology! Synoptic times displayed on weather maps are known as Z time or UTC. Mesoscale Meteorology Weather phenomena that are small in size- too small to be shown on a weather map- are referred to as mesoscale. Mesoscale events range from a few kilometers to several hundred kilometers in size. They last a day or less, and impact areas on a regional and local scale and include events such as: ThunderstormsTornadoesWeather frontsSea and land breezes Mesoscale meteorology deals with the study of these things and how the topography of a region modifies weather conditions to create mesoscale weather features. Mesoscale meteorology can be further divided into microscale events. Even smaller than mesoscale weather events are microscale events, which are smaller than 1 kilometer in size and very short-lived, lasting minutes only. Microscale events, which include things like turbulence and dust devils, dont do much to our daily weather.

Principal institutions of European Union Essay Example | Topics and Well Written Essays - 1500 words

Principal institutions of European Union - Essay Example Britain joined the European Economic Community in 1973 and since then, European law has become a significant part of the laws of the UK (Adams, 2013). The Maastricht Treaty which came to force in 1993 officially changed the name of the EEC to the European Union and integrated the three main wings of the European communal cooperations into the European Union. The European Communities Act of 1972 integrated European Union Law into UK Law (Adams, 2013). This implies that the UK is a signatory to the European Union and it has to adhere to rules, regulations and directives. The various institutions of the European Union therefore engage in laws that are directly or indirectly applicable to the UK. The main institutions of the EU are hereby discussed below alongside their impact on the making of European Union laws. The European Council of Ministers is the main legislative arm of the European Union (Gerven, 2010). The Council of Ministers was set up by the Treaty of Nice that all the member states of the European Union signed. Article 203 of the Treaty of Nice states that "a representative of each member state at ministerial level authorised to commit the government of the Member State". This means that the Council of Ministers, popularly known as Council of Europe is constituted of a minister of state who is recognised under international law. Such ministers come together to make laws and rules for the Union. The Council of Ministers varies according to the matter or subject under discussion. Thus, if the matter in question is about Agriculture, the Agricultural Ministers of each member state would have to be present at the council meeting and when they make laws, it is authorised and approved by the states through their ministers (Richardson, 2012). The primary function of the Council of Ministers is to coordinate and make policies that are binding on the institutions and

New technologies have introduced communication devices such as smart phones and computer-related devices. One longer has to travel and meet face-to-face in order to deliver a message. The new technological devices have made the world appear like a global village since individuals from different continents communicate real time and use video links to see each other during the conversation. Individuals have become accustomed to new technological devices such that they do not imagine a world without them. To make it worse, some claim they cannot fail to pick calls or reply to messages while driving. For instance, Roman admits that he responds to calls and text messages while driving and claims that he cannot stop (Turkle 170). The influences the new technologies have brought are enormous. Previously, I did not see the need to own an expensive and sophisticated phone such as a smart phone. However, time has proven me wrong because the influence of my peers and the changing times have prompted me to buy one. After owning the smart phone, I came to realize the benefits I was denying myself. The device has made my work easier because I do not need to ask anyone for direction, especially when I move to new locations. I use it to navigate using the available map and other compass devices. I have downloaded many applications such as Whatssup and joined many social groups such as Facebook and Twitter. I connect with my friends and family whenever I want from anywhere. I find the smart phone helpful and dread the time I delayed purchasing one. I take pictures when touring new places and store in the device’s memory. The device allows one to print the stored photos and send them to friends and relatives. The refore, when outside home, I always keep in touch and send updates of my status to my family. The use of

Measures Taken for Reducing Maid Abuse in Singapore Essay Example for Free

Measures Taken for Reducing Maid Abuse in Singapore Essay There are approximately 150,000 migrant domestic workers (MDW) in Singapore and many of them suffer forms of abuse – physical and sexual violence, food deprivation, confinement in workplace and late or non-payment of salary. In 2011, an estimated 4000 MDWs ran away from their employers’ home, many of them frustrated, overworked and underpaid. (TWC2, 2011) The Singapore law doesn’t stipulate a minimum wage or mandatory rest days in contracts for these domestic workers. Instead, many initiatives have been put in place to protect the interests of these workers. (Agence France Presse, 2003) From January 2005, workers seeking to enter Singapore as MDWs have to be at least 23 years of age and have completed a minimum 8 years of formal education. They must also sit for an entry test in English to validate the worker’s linguistic, numerical and practical abilities. These measures are aimed at improving the overall quality of workers who will be working in Singapore households in an effort to promote harmonious working relationships with their employers. These workers will also be in a stronger position to understand their rights and seek protection or recourse under Singapore law should they suffer any form of abuse or ill treatment. Ministry of Manpower (MOM) has also put in place training courses to educate employers. Starting from April 2004, first time employers of MDWs have to attend a compulsory Employers Orientation Program, which educates employers on their obligations towards these workers. It underlines good employment practices to promote mutual respect between both parties. A new accreditation system has also been put in place to regulate employment agencies, which provide recruitment and placement services of these MDWs from June 2004. The accreditation requirements include proper orientation of MDWs, employer education in regards to their obligations towards the welfare of MDWs and the facilitation of written employment contracts between MDWs and their employers. Failure to achieve this accreditation will result in agency’s license being revoked. While these measures work towards protecting MDWs interests and well being, the challenge to make sure agencies and employers follows suit still exists. There are still cases of physical abuse reported and many more go undetected and unreported even though the government has stiffened penalties for acts of abuse against MDWs. Moreover, there are currently no regulations on fees charged by these agencies resulting in excessive fees being paid by MDWs to secure employment in Singapore, some of whom receive no salary for up to a year just to pay off these fees. (HRW, pg 48-51) Regulations should be passed to limit the extent these fees are being charged to MDWs. Singapore’s government also charges employers of MDWs a monthly levy of S$345 on top of a bond of $5000 per worker. This tax allows the Singapore government to collect approximately $400m each year, of which very little goes towards improving support services for these workers. The government should in turn use these taxes to help to create awareness of maid abuse or to pass it on to the various Volunteer Welfare Organisations such as Humanitarian Organization for Migration Economics and Transient Workers Count Too to work on prevention of maid abuse. It is MOMs requirement that the maid go for a medical check up every six months. Beside this measure, they could also conduct regular spot check on the maid, just like what they done for the foreign construction workers to check on safety measurements.

Tale of the Haunted GPS Navigation System Essay -- Urban Legends

Tale of the Haunted GPS Navigation System The storyteller, who happens to be my cousin, currently works as a math teacher. He is 24 years old and lives at home with his mother and father. His mother, a talented artist, works for the United States Postal Service and his father, who is an electrician, installs security systems for homes and offices. Both of his parents are Korean and although his older brother was born in Korea, he was born in the United States. He is very athletic and enjoys skateboarding and snowboarding. When he was younger he was always the one most willing to take risks in the family. He is also a talented guitarist. He also has deep religious convictions as a devout Christian, when asked what he thinks of ghost stories in general he merely shrugged them off as stories meant for entertainment rather than anything of merit. When asked about the origins of the particular story he said that a friend mentioned it at a party several years ago. The story was told during a snowboarding trip to Vermont this past spring. There were two members in the audience (including myself) and it was told in the room of the Red Oak Inn at around 11:30 PM. My cousin, who was seated on his bed, made eye contact with each audience member as he began his story. A couple was interested in buying a navigation system so they visited several stores in search of the best deal. In most cases the prices were too expensive for them so they went on craigslist and found a great deal on a used GPS system. They received the unit in the mail and wanted to try it out right away. They installed their GPS unit [imitates placing a GPS unit in a car windshield with hands] in the car and turned it on. The wife, out of curiosity, hi... ...of the motivating factors behind their purchase was the fact that the unit was cheap. There have been many cases where items posted on sites such as craigslist or ebay that have very attractive prices turn out to have serious defects or are fake. In this case the couple bought a haunted GPS unit that had killed the previous owner. The story reveals society’s general fear of things that are second-hand or things bought through websites where users, not companies, sell their wares. The story of the haunted GPS unit served as a commentary on the consequences of over-reliance as well as blind trust in not only navigation units, but also technology in general. It also served as a warning against buying items that were at too good to be true prices from websites where the sellers are not reputable companies but users who have no desire to maintain a good reputation.

A Book Review on “Under a Cruel Star” Essay

A narrative memoir of the author Heda Margolius Kovaly given in her book Under a Cruel Star depicts the tragic history and stories of various chaoses including the Czechoslovakia turmoil and Soviet Union. In here, she tells how their lives moved through dilemma just to adapt in certain situations where her religious practice, gender, social and economic status are relevantly part in her way of living. Heda Kovaly’s narration is made up of her observations, lessons learned, experiences, ideas, and some of her justification towards her decisions made, in which we can conclude that some are without the presence of her willingness or should we say just an act of woman’s submissiveness to her husband. As a brief recapitulation of the book, Heda opened up telling that the three forces shaped in the past history also formed her life as a whole. She recounted every episode of their lives although not in details. It started up from Heda Kovaly’s experiences in 1941 before he got married to Rudolf Margolius during the turmoil in Prague, Czechoslovakia under post-Nazi regime. Her deportation from Prague to Lodz ghetto in Auschwitz opened up disruption of her supposedly peaceful life. She mentioned how she managed to escape from the marching prisoners of war heading to Reich, Germany. Right after Prague chaos, she met his childhood sweetheart Rudolf and got married to him. Rudolf was a survivor of Nazi government’s several concentration camps; however, unlike other Nazi victims who utterly opposed communism ideals, Rudolf embraced this thought and therefore got a life out of it. Heda became a follower of her husband’s beliefs and principles. It ended up when Rudolf got arrested in 1951 with the reason of advocating his ideology, and it followed his execution after the Stalinist trials in which Heda herself witnessed. Just imagine how painful and helpless it is on Heda’s part to see his husband dying in the prosecution, and this feeling of Heda has shared with her readers as it magically brought by her narration. Hardships and sufferings pushed Heda to live despite harassment of the society as a result of just being Rudolf’s wife and partner. Heda remembered how the society persecuted her and her son by means of forced evacuation from their rented house, hastily and rudely dismissal from the hospital amidst necessary medication, and religiously losing her job one after another. Such difficulties ran for five more years following Rudolf’s death. However, Heda’s willingness to live continued as she believes that their journey did not stop on Rudolf’s imprisonment and execution. Instead, it opened up another episode of her life where she survived really hard to be able to support and augment their child’s basic needs. More than a decade after that nightmare, Heda received an invitation from the Czech government as the latter said revocation of Rudolf’s name in the Stalinist show trial. Heda insisted total absolution of Rudolf’s name and a publicly retrial of the case. She also radically demanded that the Czech government has to admit solely the guilt that it has to make a public apology for the victims including Rudolf and his family. Thus began Heda’s open advocacy opposing Communism as well as Stalinism, and to encourage everyone to stop anti-Semitism views whether in Czechoslovakia, in Europe, or in the world as a whole. Heda wrote the book basically with the purpose of enlightening the readers about such experiences of a Jewish family, specifically a Jewish woman in Czechoslovakia under Nazi government and Communism though she mentioned dedicating the book for her son to Rudolf Marqolius. Her audience could be anyone who is interested in historical topics such as political and social evolution in Europe and their impacts on the world history in general. Though the book failed to follow proper formatting as it is only a narrative of Heda’s own story and experiences and that it is transcribed in an informal way, it also fails to meet historical analysis and proper illustration. However, the help and information it could bring to the students who are known being idealists are quite immeasurable. They will surely love reading this book again and again as it inspires their modern principles and ideals. Under the Cruel Star is not designed to be a university textbook but it helps in a way educating the students especially of History courses such as History 101 which tackles Themes in Modern History like ours. Surely, Heda Morgolius Kovaly’s story could be a glass of cold water poured on fire. It means that a communist believer who happens to read this book would change his belief reading this. It makes possible as the testimony entails drastic impact to the lives of innocent ones in the past. On my part, the book signifies peaceful victory over chaotic ambiance having Heda’s view of love over hate. Like Heda who happens to forgive the tragic past, and use it to advocate equality through her text irregardless of many difficulties including her religious beliefs being a Jew. To conclude, I should say that I have learned through this book that what really important is how a victim of a wary world remains peaceful at heart in the end.

Le Petti Gourmet

Jim O’Connor, President and Owner of Le Petit Gourmet, received a shocking phone call while vacation in California, which informed him that his business is going to shut down indefinitely due to the outbreaks of hepatitis A in his catering facility. Le Petit Gourmet was a family catering business that had been operating in the Denver metro area for more than 30 years. Le Petit employed between 150 and 200 people, 75 of whom were full time. Along with Le Petit was perceived as the most expensive and upscale caterer in Denver, O’Connor also want his business to be known for good food on all levels, from cookies to lobsters. Le petit Gourmet’s business had been on the upswing in recent years. On November 22, Health Department notified O’Connor that his kitchen manager infected by hepatitis A, and by Nov 30, the doctor confirm the case. Due to the further outbreak on Dec 30, Le Petit Gourmet is being shut down completely, and the health departments have ordered food-service workers in metro Denver area to using gloves or utensils when handling food in prevention to hepatitis A. In addition, Le Petit Gourmet employees were forbidden to work as food-handlers anywhere else until January 31. When he returned from San Francisco, Jim O’Connor found that his business and family were under siege. The media, his insurance agents, lawyers, and health department inspectors, Le Petit employees and customers were waiting for his explanation on how he going to handle the hepatitis outbreaks. Initially, he hired a public relations firm to assist him, but decided that he needed to take a more active role to save his business. First of all, he personally called the victims of hepatitis and apologized for what had happened. He also meets with his employees to calm their fears. Afterward, he make sure that his company will have enough cash flow on hands to handle this crisis by delaying payment to his vendors and negotiated a larger mortgage, because he realized that he doesn’t have income for undetermined amount of time. To win back the public on their side, O’Connor and his staff decided to dumped $45,000 of food products into the trash. Many of these items were unopened and frozen products, not part of the infected food. O’Connor was able to maintain his employees during the outbreaks, he honestly tell them that pay cut was imminent in the future, but if your stand by me and help me, I will commit to pay you back when the business is getting better. He also states to the employees that the infected person have been left Le Petit Gourmet, we are very safe working here in Le Petit Gourmet. When he have all the information he need, he held a news conference at the Le Petit Gourmet facility and explained what had happened and what he and Le Petit Gourmet prepared to do about the crisis. During the outbreak periods, other catering companies was worried that this crisis would effects their companies, so they mailed out letter to inform their clientele that this only happened to Le Petit Gourmet and will never happened against them. Due the O’Connor and his staffs diligent works, Le Petit Gourmet finally reopened on January 11, and they have their first catering job on January 14. Main Issues The main issues for this case was how O’Connor able to handle this crisis with ease and win back the reputation for his business. When the crisis first happened, O’Connor is put in a very tough spot, not only that he has face the media, health department, employees, etc†¦ they all waiting for him to inform them what is really happened behind this mess that cost by Le Petit Gourmet. I think that O’Connor did excellent job step by step to get his business reopened and back to business as soon as possible. First of all, he realized that he not going to have enough cash flow on hands to solve the problem, because he will have no income for long period of time due to the out breaks. Smartly, he asked his vendors for a delay payment, and also negotiated a larger mortgage to make sure to have enough cash on hand to solve the crisis. Money could be use to compensate the victims or pay for attorney fees, and also need to pays his employees. Second of all, he was acting as a public relations spokesperson, who called all the victims and apologized for what had happened. He also met with his employees to calm their fears by telling them that the individual to whom the initial outbreak had been traced had already left the company, we are in a very safe working environment. He honestly told his employees that pay cut were imminent in the immediate future and their long-term status at Le Petit Gourmet was cloudy, but if they can stay on his side during this difficult time, he will make commitment to help them later on. In addition, he also dumped $45,000 dollars of food products into the trash, to inform everyone that everything that has to do with hepatitis A will be destroyed and nothing will be held. I am most impress with O’Connor was that he didn’t shy away from the media, after he gather all the information he needed and collected himself personally, he held a new conference at the Le Petit Gourmet facility and explained what had happened and what he and Le Petit Gourmet as a company were prepared to do about the crisis. Finally, due to the diligent works from O’Connor and his staffs, Le Petit Gourmet was finally reopened on January 11, and got they first catering job on January 14. I believe that O’Conner manage everything very well during the crisis, he win back the reputation of his company by holding a news conference and inform everybody what has happened, and win back his employees by honestly tell them what is going to happened in the future, he didn’t hide anything from anyone. He tells everyone what he thinks and what he going to about it.

Comparison of observation and sampling as methods of research

Comparison of observation and sampling as methods of research Introduction Research is the act of finding knowledge by such means as investigations so that facts can be established. Research variables are those individual empirical items that can take on different values. This work discusses two methodologies of research namely; observation and sampling.Advertising We will write a custom research paper sample on Comparison of observation and sampling as methods of research specifically for you for only $16.05 $11/page Learn More Its main focus is the advantages and the disadvantages of each method in relation to the different techniques involved in each method. The techniques represent the multicultural aspects in relation to traditional research methods. Observation Observation is the act of receiving and recording data into the human senses or in scientific apparatus. It can also be defined as a method of receiving knowledge. The way a researcher looks at things, or any data that is collected from the field are also known as observations. Observation needs a rigorous preparation that also includes formulation of hypotheses (Educationforum, 2010). During a research operation, researchers has to ask themselves questions about a phenomenon, observe the phenomenon, hypothesize it, predict a logical sequence by extrapolation and inferences, test the hypothesis experimentally, and finalizing the process by making a conclusion based on the results of the test. From the above sequence, it is evident that observation plays a big role in the second and the fifth steps. Observation, as a way of research is classified into two techniques namely non participant and participant techniques. It is worth noting that the two methods can be used simultaneously. In the non participatory technique, the researcher does the observation but does not join the group in question. On the other hand, the researcher does the observation while joining the group in the participatory technique. One of the advantages of observa tion as a method of research is that it can generate data that is deviant. Despite these deviations that may render the data unreliable, a strong fact that makes the method useful is that the data is highly representative. The method can also be used to study a small population (Ngo, 2010). It is also applicable where interviews are quite expensive or untimely like during investigations that involve the emotional issues of toddlers. Another advantage of this method that seems to be quite obvious but often forgotten is that the researcher can study a particular group of population that other methods cannot be employed to study.Advertising Looking for research paper on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More A particular behavioral pattern within a specified population can also be studied on a daily basis at specific localities (Ngo, 2010). In special instances, especially when using participatory techniques, a res earcher can obtain highly accurate data that is also very rich. Observation techniques do also have their own disadvantages. The findings of observed data can lack the aspect of reliability (Educationforum, 2010). The data may reflect that of superficial observations and this method can only investigate a small number of population at a time. According to recent studies, during these investigations, a researcher may influence the population in question to behave differently. Other disadvantages of observation as a method of research include fatigue of the researcher due to high involvement, presence of ethical problems particularly when dealing with a population that engages in illegal activities and the misrepresentation of data during non participatory observation. Sampling A sample is a single item within a large population of reference. Samples are usually used when the individual items in the population are too numerous in number to count or the main item of reference is too hu ge to investigate. It is through the collected samples that a researcher can find the desired details that they can use to make inferences. Sampling is the process whereby a sample of a particular population is studied for further details and inferences and extrapolations made to the specified population. There are many different types of sampling depending on the method of classification, for instance, there are random samples and nonrandom samples. Sampling employs different techniques that include, simple random, stratified random, cluster, stage, purposive, quota, snowball, volunteers, accidental, and convenience. Their advantages range from one sample to another. However, compared to research methods such as observation, their advantages seem to be following a general trend. Even the disadvantages behave in a similar manner. Thus, the main advantages are that some techniques of sampling are highly representative especially the simple random. Specific groups are usually represen ted and the methods used ensure that much localized populations are not missed. Sampling also ensures that there is a balance of group sizes especially if the investigations include the selection of multiple groups.Advertising We will write a custom research paper sample on Comparison of observation and sampling as methods of research specifically for you for only $16.05 $11/page Learn More In specific sampling methods such as quota method, there is a certainty in precise selection of numbers of the items in questions, which have appropriate characteristics. Sampling also offers the opportunity to investigate a group in which no identifiable clusters exist. Last but not least, sampling is an inexpensive way that can be viewed in terms of economies of scale. This means that a researcher can investigate sufficient numbers of a study using fewer resources. At the same time sampling in general is more reliable since the sample data collected from the selected s amples makes room for a quick inference on the population parameters (Emathzone, 2008). This method also has its own disadvantages. Most specific sampling techniques such as simple random are not possible to execute without a complete set of population members. At the same time, these methods are not quite economical to achieve and may involve a lot of time. Other sampling techniques such as stratified random, are pretty demanding in terms of effort. They also require a more careful definition of strata. Sampling as a method of research demands a lot of care in choosing the techniques. A researcher has to be careful in the choice such that the technique used should be the most appropriate and at the same time economical in terms of resources and time. Stage sampling is pretty complex because it combines limitations of cluster and stratified random sampling (Emathzone, 2008). In the purposive technique, samples are not easily defensible as being representative of the entire populatio n in question. This is because there may be an element of subjectivity operating within the researcher’s mind and their specific operations. In some instances, it may not be possible to prove whether the sample is representative of the population in question. Good examples of this are the quota and the snowball techniques (Educationforum, 2010). Another disadvantage of sampling, especially when using the volunteer, accidental and convenience technique is that the method can be highly unrepresentative Conclusion The above research methodologies can be useful in executing research projects that involve different sizes of population. Sampling can be used to investigate large populations while observation is used to investigate particular features in small populations.Advertising Looking for research paper on psychology?

Its safe enough to be used around food and in contact with skin. Its much easier to recycle this metal than it is to purify it from ores. You can melt old aluminum cans to get molten aluminum. Pour the metal into a suitable mold to make jewelry, cookware, ornaments, sculptures, or for another metalworking project. Its a great introduction to home recycling. Key Takeaways: Melt Aluminum Cans Aluminum is an abundant and versatile metal that is easily recycled.The melting point of aluminum is low enough that it can be melted with a hand-held torch. However, the project goes more quickly using a furnace or kiln.Recycled aluminum can be used to make sculptures, containers, and jewelry. Materials for Melting Aluminum Cans Melting cans is not complicated, but its an adult-only project because high temperatures are involved. Youll want to work in a clean, well-ventilated area. Its not necessary to clean the cans before melting them since organic matter (plastic coating, leftover soda, etc.) will burn off during the process. Aluminum cansSmall furnace of the electric kiln (or another heat source that reaches the appropriate temperature, such as a propane torch)Steel crucible (or other metal with a melting point much higher than aluminum, yet lower than your furnace- could be a sturdy stainless steel bowl or a cast iron skillet)Heat-resistant glovesMetal tongsMolds into which youll pour the aluminum (steel, iron, etc.- be creative) Melting the Aluminum The first step youll want to take is to crush the cans so that you can load as many as possible into the crucible. Youll get about 1 pound of aluminum for every 40 cans. Load your cans into the container youre using as a crucible and place the crucible inside the kiln. Close the lid.Fire up the kiln or furnace to 1220 °F. This is the melting point of aluminum (660.32  °C, 1220.58  °F), but below the melting point of steel. The aluminum will melt almost immediately once it reaches this temperature. Allow half a minute or so at this temperature to assure the aluminum is molten.Put on safety glasses and heat-resistant gloves. You should be wearing a long-sleeve shirt, long pants, and covered toe shoes when working with extremely hot (or cold) materials.Open the kiln. Use tongs to slowly and carefully remove the crucible. Do not place your hand inside the kiln! Its a good idea to line the path from the kiln to the mold with a metal pan or foil, to aid in clean-up of spills.Pour the liquid aluminum into the mold. It will take about 15 minutes for the aluminum to solidify on its own. If desired, you can place the mold in a bucket of cold water after a few minutes. If you do this, use caution, since steam will be produced. There may be some leftover material in your crucible. You can knock the dregs out of the crucible by slapping it upside down onto a hard surface, such as concrete. You can use the same process to knock the aluminum out of the molds. If you have trouble, change the temperature of the mold. The aluminum and mold (which is a different meta) will have a different coefficient of expansion, which you can use to your advantage when freeing one metal from another.Remember to turn off your kiln or furnace when youre done. Recycling doesnt make much sense if youre wasting energy, right? Did You Know? Re-melting aluminum to recycle it is far less expensive and uses less energy than producing new aluminum from the electrolysis of aluminum oxide (Al2O3). Recycling uses about 5% of the energy needed to make the metal from its raw ore. About 36% of aluminum in the United States comes from recycled metal. Brazil leads the world in aluminum recycling. The country recycles 98.2% of its aluminum cans. Sources Morris, J. (2005).
