From Corded to Cordless Essay Example for Free

From Corded to Cordless Essay From the construction site to the home, the electric drill is a commonly used tool in todays society. The electric drill has been refined throughout the last century to form a tool that is both versatile and aesthetically pleasing. The 20th Century drill has come a long way from it 19th Century predecessors. Australian, Arthur James Arnot, patented the worlds first electric drill in 1889. Arnots electric drill could perform all the tasks of an ordinary drill but with much greater efficiency. Then in 1895, German, Wilhelm Fein invented the first cordless (DC) electric drill. A cordless electric drill is a type of electric drill which uses rechargeable batteries, i.e. direct current (DC). Feins drill could spin a 1200 rpm (revolutions per minute) and relied on the user to press against the back of the drill in order to achieve good leverage. These early designed were not ergonomically tested and an issue arouse because the drills were somewhat heavy due to the metal (mainly steel) components. It was not till the early 1900s that the heavy steel exterior was replaced with the much lighter aluminum. Early cordless (DC) drills used Nickel-Cadmium (NiCd) batteries. NiCd batteries have a limited lifespan, self discharge and ultimately will internally short circuit due to dendrite growth. This poses a hazard when disposing of such NiCd batteries. It was for this reason and others that there was a move from NiCd batteries to Lithium ion batteries at the beginning of the 21st Century. The main advantage of using Lithium ion batteries is the dramatically shorter charging time and the longer lifespan. Lithium ion batteries also make the drill much more versatile because; unlike NiCd batteries, Lithium ion batteries have a constant discharge rate. The year 1917 marked the beginning of the designs we see today. Black and Decker patented a trigger like switch mounted on a piston-grip, the first hand held drill of its kind. This innovative design helped to increase productivity as the user had a free hand to perform tasks that, previously, may have required another person. The 1930s/40s saw a boom in the mass production of electric drills. The electric drill was made available to a greater number of people around the world. Societys homeowners wanted to take a more active role in the maintenance and repair of their homes. Mass production of the electric drill lead to the development of more powerful, more efficient, more versatile electric drills. Society at the time had a great impact on the design and aesthetics of the electric drill. Manufacturers realized that they could not sell industrial looking tools to common homeowners, so product materials began to change during this time. Manufacturers started to use plastic, which considerably reduced the weight and very much added to the appeal of the electric drill. The use of plastic also had an even greater positive effect, which was to prevent the user from suffering an electric shock if the electric drill was the short circuit. The exterior of the electric drill was also extensively changed, as societys homeowners wanted products that were aesthetically pleasing. Hence the lustrous yellow base color and contrasting black grip of most modern electric drills. The willingness of manufactures to change their design to accommodate the consumer desires is a reflection of societys impact on the design of the electric drill.

Susan Smith :: essays research papers fc

Susan Smith In the blink of an eye, North America was informed of Susan Smith's tragic loss of her two young boys. No one would have guessed that such a violent crime could have occurred in a small town . Throughout the ordeal , police began to see the flaws in Susan Smith's story. This lead to suspicions, causing the police to make Susan Smith their prime suspect. Days later, Susan Smith confessed to the hideous crime she committed, leaving the nation in disgust. The actions of Susan Smith, which were based on her background and the events in question have left a profound social and legal impact on society's views of violent crimes. Susan Smith lived what most would consider a normal life up to the time before the event concerning the murder of her two children. The only exceptional incident in her past was the suicide of her father when she was eight years old. Susan met her future spouse David Smith, at the age of nine- teen. The couple later went on to have two children, Michael and Alex. She was described as "well-known and well-liked" by her friends, neighbours and relatives. None of her friends or neighbours could have expected Susan Smith to commit such a horrible crime. The event took place in a small town in Union, South Carolina. On October 25th Susan Smith explained that she was "heading east on Highway 49 when she stopped at a red light at Monarch Mills about 9:15 p.m., and a man jumped into the passenger seat." She described the man "as a black male in his late 20s to early 30s, wearing a plaid shirt, jeans and a toboggan-type hat." She said that the abductor held her at gun point and told her to drive. She drove northeast of Union for about 4 miles. Then the man suddenly told her to stop the car. Mrs. Smith said she asked if she should pull over, but the man said for her to stop in the middle of the road. She claimed that she begged for the release of her two children, who were still strapped in the back seat, but it was to no avail. The town sent out thousands of volunteers to search through "over five hundred square miles for the children." The story later went national but there was still no sign of the children or the attacker. The town Sheriff, John Wells, with the help of an FBI computer system went after every lead that came in from psychics, crackpots and well-meaning citizens.

Web Site Publishing Process

Web Site Publishing Process The first step to publish a brand-new web site is to find the best host for your needs. There are many different options for Web hosting. The best one is going to depend on the type of site that is being created. Almost all sites will fall under one of the next three categories: personal or hobby site, small business site, or Ecommerce or high-traffic site. It is going to be the size, complexity, and expected traffic load of the site that are going to need to be considered when shopping for a host. Personal and Hobby sites are typically used for sites that will be used to communicate with friends and family and/or share information about hobbies with other people. These sites will typically be small and have low-traffic. Personal and Hobby sites are easier to publish and less expensive. There are two free options in this category. The first is your internet service provider as most of them give customer’s access to a personal Web page as a part of their regular service. This option does have strict limits on the amount of bandwidth the website is able to use though; too many pictures can push the website over the limit. The second option is free web hosts. This allows someone to get a free site and the host gets to advertise on it, although storage and download amounts are an issue here too. With this option the host is able to shut down the website if it exceeds the bandwidth allotment until the next month when the bandwidth counter restarts. Small business sites are sites that will contain basic company information. These sites are typically called â€Å"brochure sites†. This is because the information in the website can probably be found on a printed advertisement brochure. These are pretty simple sites, but because they are still a business the creator will want a reliable host and will not be shut off unexpectedly. The creator will choose their own domain name. Ecommerce sites are sites where individuals and/or small businesses start to sell products and services online and collecting online payments. These types of sites can get a little pricey when trying to find a host because these sites will need a working shopping cart system, an online merchant account, and a Web host that supports all of that. Once the needs of the host have been determined and you have a valid domain name the next step will be to publish the website. There are three basic options: FrontPage extensions, HTML editor with FTP (File Transfer Protocol) capability, or a standalone FTP program. FrontPage does not work well with an FTP process as it uses FP extensions. HTML editor and the standalone FTP program both use the FTP process to upload all files for the website. Check List: ?Find the right host ?Create a valid domain name ?Design the website ?Publish the website The two web hosting companies that I am going to compare are hostgator. com and hub web hosting. Below is a list of what each offer: Web Hosting CompanyWeb Hosting EssentialsWeb Hosting ExtrasWeb Hosting Review HOSTGATOR. COM? $4. 95 Monthly ?Unlimited Disk Space ?Unlimited Bandwidth?

This site offers site hosting for $4. 95 a month which includes unlimited disk space and unlimited bandwidth. Hub web hosting offers site hosting for $3. 95 a month which includes unlimited disk space and unlimited bandwidth as well. They each offer a lot of extras like unlimited domains. The difference is that Hub web hosting is a simple web hosting site, while hostgator. com is a little more technical. I would consider using hub web hosting for my own Web site as it seems to be more for the beginner website developer and seems to be easier than the other.

Food Labels Should Contain Information on GMOs and Not at an Increased Price - Free Essay Example

Sample details Pages: 3 Words: 773 Downloads: 5 Date added: 2019/02/14 Category Health Essay Level High school Tags: GMO Essay Did you like this example? Every single human being, regardless of socioeconomic status, should be given the right to choose what goes into their bodies. However, one cannot make this choice if they are unaware of the contents within their food. Those suffering financially may also have little control over their diets due to usual high costs that accompany good-quality foods. Genetically modified organisms (GMOs) are genetically altered to contain genes from another specie. Many farmers genetically modify their crops to make them withstand harsh temperatures and be resistant to insecticides and herbicides (Jimenez Pulos, 2016). We may be unware that many of our foods likely contain GMOs as food labels fail to disclose this information. Don’t waste time! Our writers will create an original "Food Labels Should Contain Information on GMOs and Not at an Increased Price" essay for you Create order There are a variety of contradictory studies regarding the safety of GMOs. Some studies suggest foods containing GMOs may be harmful to human health while others disprove these claims. Despite the extensive amounts of research about GMOs, these controversies still exist and there is no absolute certainty of whether they are completely harmful or harmless. Many food containing GMOs are engineered to resist the herbicide glyphosate. Through various studies, glyphosate is proven to impact the reproductive health of females. It is shown to have detrimental effects on the endocrine system (Thongprakaisang, Thiantanawat, Rangkadilok, Suriyo, Satayavivad, 2013). Behaving similar to the estrogen hormone, glyphosate acts as foreign material in the body and can disrupt the development of a fetus (Aris Leblanc, 2011). Through a study testing the urine samples of 71 pregnant women, glyphosate was detected in 93% of them, confirming that glyphosate exists in some foods (Fairbanks, 2018). Neuroscientist, Deborah Kurrasch, suggests that there is an insufficient amount of information available to assess the behaviour of glyphosate in the body. She questions if glyphosate actually interferes with the function of hormones, arguing the ambiguity of the molecule that binds with glyphosate. (Zimmer, 2018) Based on the level of uncertainty, definitive c laims about glyphosate should not be made. These contradictory claims make me apprehensive about GMOs. As a female, I can understand why pregnant women may not want to take the risk of consuming genetically modified foods. Why eat something that can potentially be harmful to not only themselves but also their baby? Pregnant women should be aware of the contents within their foods for the sake of their own and their child’s health. Glyphosate is also thought to be carcinogenic. In 2015, the International Agency for Research on Cancer proposed that glyphosate is â€Å"probably carcinogenic in humans† (Guyton, et al., 2015). A year later, following various tests on rats and mice, the WHO and FAO reveal that glyphosate does not appear to be a cancer-causing agent in rats but at increased levels, can be harmful towards mice. This leads to the conclusion that glyphosate may not necessarily be a cancer-causing agent for humans (Tarazona, et al., 2017). These claims are concerning as they still make me question the safety of GMOs containing glyphosate. How effective are animal studies in predicting the true effects of glyphosate in humans anyway? It is important to consider that introducing GMO information on food labels will likely increase the prices of these food products (Byrne, Pendell, Graff, 2014). According to a poll commissioned by the Canadian Biotechnology Action Network, approximately 88% of Canadians are in favour of GMO labelling on food products (Smith, 2016). The remaining 12% of Canadians may not be in favour of GMO labelling fearing that there will be an increase these food products. Considering the social determinants of health, it is important to consider that investing in an organic diet is not realistic for everyone. Organic foods may be quite costly for many average and lower-class Canadians. The choice to eat organically in order to avoid the potential risks of GMOs may be out of their budget and therefore beyond their control. Despite the studies, I remain unsure and skeptical about GMOs and their effects on human health. Regardless of one’s stance towards this biotechnological phenomenon, I am confident that many people want to know what is going into their bodies. Ultimately, food labels should contain information about GMOs and there should not be an increase in price for doing so. Every single person deserves the right to know the contents within their food. We should be able to make the choice for ourselves about whether or not we want to consume GMO containing products. I would send my work to Maclean’s, a Canadian magazine, as my topic deals with a health and social justice issue. My editorial contains research about the opinion of Canadians on GMO food labels. I also consider the socioeconomic status of different Canadians and how this may impact their opinion on whether food labels should contain information about GMOs.
