Population†¦A Problem That Most of the World Simply Disregards There are over Six Billion people inhabiting the planet earth today and that number is growing. â€Å"In the six seconds it takes you to read this sentence, eighteen more people will be added† (Ehrlich 9). The total population of the World, projected on October 23, 2001 at 6:28:09 pm GMT was 6,181,600,089 people (U.S. Bureau of the Census). Each hour there are 11,000 more mouths to feed; each year more than 95 million. Nevertheless, the world has hundreds of billions fewer tons of topsoil and hundreds of trillions fewer gallons of groundwater with which to grow food crops than it had in 1968. Millions of people every year are dying because they are not getting enough†¦show more content†¦They are linked â€Å"to food-production statistics, to the prospect of a billion or more deaths from starvation and disease, and to the possible dissolution of society as we know it† (Ehrlich 11). Our planet is overcrowded, we have too many people and that affects both our ecosystem, economic system, and how our society runs. Nature has it’s own way of eliminating a problem, and it’s problem is people. We’re causing the problem for ourselves. We created global warming because we emit too many CFC’s into the atmosphere by driving gas-guzzling vehicles, and not monitoring our industrial output. We’ve created huge holes in our protective ozone, which then cause droughts and crop failures that may lead to premature deaths of a billion or more people in the next decade. In addition to more frequent and more severe crop failures, projected consequences of the warming include coastal flooding, desertification, the creation of as many as 300 million environmental refugees (Menk 34), alteration of patterns of disease, water shortages, and general stress on natural ecosystems. AIDS may have existed for thousands of years, but because people are in constant contact with hundreds of other people, the disease has spread like a wildfire killing hundreds of millions.

Keeping The Minimum Legal Drinking Age - 2656 Words

Walking In a Straight Line Writer Dedel Kelley said, â€Å"The proportion of underage youth who drink has not changed significantly over the past decade in the United States. Indeed, if anything, they are starting to drink at a younger age, and their drinking patterns are becoming more extreme.† Keeping the minimum legal drinking age (MLDA) at twenty-one or lowering it to the age of eighteen has been a continuous issue in the United States. People, mostly adolescent teenagers, say it should be lowered because if one is able to vote at the age of eighteen, they should also be allowed to drink. Sure, when a seventeen-year-old turns eighteen they are considered an adult, but age does not define maturity; just because they would be classified as an adult does not mean they can be responsible and handle alcoholic beverages like a parent, for example. The legal drinking age should remain at twenty-one and should not be lowered to the age of eighteen because people who are eighteen y ears old and younger are still juvenile. If the legal drinking age were to be lowered to eighteen, teenagers put society at risk because most will go behind the wheel while under the influence of alcohol; they are not only putting society at risk but also themselves because they could start an early binge drinking habit and affect their health. Drinking generally increases in popularity amongst teenagers each year, which fuels the controversial issue of lowering the drinking age to eighteen or keeping itShow MoreRelatedKeeping the Minimum Legal Drinking Age1283 Words   |  6 Pagesthe minimum legal drinking age in the United States or not.

Throughout generations, adolescent behavioral trend has been a matter of concern for families and schools. Their rebellious attitude has drawn attention of many psychologists. Usual defiance includes mood swings, disobedience, anger, criticism, disagreement, and harmful habits like smoking, drugs. We will write a custom essay sample on Behavioral trend- Adolescent rebellion or any similar topic only for you Order Now Socioeconomic status of the youth is a major factor. The urge to be accepted by their peers, leads to comparison for equality. Peer pressure is perhaps the most vital and unavoidable element in adolescence. Columbia University Teachers Suniya S. Luthar and Nadia S. Ansary wrote following: In a comparative study of middle school students at the two socioeconomic extremes, Becker and Luther (2004) found that â€Å"good students† enjoyed high peer status in both suburban and urban settings; by contrast, it was only the high income youth who admired peers seen as â€Å"bad students†. Society which does not view teenagers as adults restricts their freedom, believing it to be in their best interest. Parents often believe that adolescents cannot make good decisions. This restriction of freedom leads to rebellious behavior. However, â€Å"a Cornwell study from 2006 determined that teens are more likely to consider risk while making a decision, and for a longer period of time, than adults† (Cornell University, 2006, December 12). Psychologist Laurence Steinberg says that a large factor in teenage rebellion is the natural early development of the socioemotional network. (Cited in Temple University, 2007) References Luthar,S.

Manufacturing Technology Journal Advanced -Myassignmenthelp.Com

Question: Discuss About The Manufacturing Technology Journal Advanced? Answer: Introduction The main purpose of the report is to understand the different concepts of additive manufacturing or 3D printing, which is a new technology that is being increasingly used in different industrial sectors. This emerging psychology has brought a revolution in the manufacturing industry. 3D printing or additive manufacturing has offered a new paradigm in manufacturing industry by enabling the feature of customized printing. 3D printing, which is also known as additive manufacturing, offers a speedy and cost effective solution, thus adding a competitive advantage in the market. The report discusses the working principle of 3D printing or additive manufacturing. The report further discusses whether the 3D printing is suitable for high or low volume of production. With the increasing popularity and usage of 3D printing or additive manufacturing, the traditional manufacturing process has taken a backseat (Weller, et al., 2015). The report discusses the role of 3D printing in turning the trad itional manufacturing obsolete. The increase in the growth and popularity of 3D printing is largely because of reduced labour and cost requirement (Campbell, et al., 2011). The various functionalities of 3D printing are elaborated in the following paragraphs. 3D printing/Additive Manufacturing 3D printing is also known as additive manufacturing as the process includes development of a prototype by adding a preferred material or mould layer by layer. In simple words, 3D printing is a process of joining the different layers of materials, to develop a 3D model or structure, and hence the name. 3D printing makes use of a digital model as a guide to print a 3D structure if a particular design. The layer by layer addition is very quick for low volume production and therefore it is used in developing the concept models. Additive manufacturing is a process of manufacturing that combines a large number of minuscule layers in creating a particular product. This process is however very quick. The term 3D printing is used to refer the different types of additive manufacturing and hence it is known by the name of additive manufacturing as well (Chua Leong, 2014). Additive manufacturing differs from subtractive manufacturing through a large extent, as a model is built up by adding the materials layer by layer. The simple process of adding layers by layers in development of a model helps in manufacturing complex products with ease. Additive manufacturing therefore, refers to a process of manufacturing a three dimensional design or data by subsequent addition of layer of different material. Additive manufacturing is therefore used as a synonym of 3D printing. However, the term additive manufacturing is more appropriate to consider as it describes the manufacturing technique. This helps in distinguishing 3D printing from subtractive manufacturing (Weller, et al., 2015). 3D printing in high and low volume of production The process of 3D printing is most suited for low volume of production. The process of additive manufacturing makes even the complex-manufacturing simple. However, the process of 3D printing is economics and cost effective only for low volume production. Furthermore, the layer by layer addition of materials to develop a set structure is a time consuming work in case of large volume of production. One of the main constraints for small manufacturers is the budget allocated for a particular task (Mueller, 2012). 3D printing eliminates any extra cost by reducing the number of labours and time required for completion of a project. However, in case of a large volume of production, it becomes extremely difficult to follow this process due to a time constraint. 3D manufacturing optimizes the low volumes production as the traditional manufacturing methods such as injection modelling is very expensive. Therefore, it can be said that 3D printing is a growing opportunity for low volume of production. 3D printing is increasing used in modelling of engineering and architectural works and finds extensive usage in chemical industry and in building medical implants as well. 3D manufacturing however has a capability and potential to be used in high volume of production as well (Kietzmann, et al., 2015). Situations in which 3D printing is valuable 3D printing was initially developed for rapid prototyping. However, in course of time, it found its application in rapid manufacturing as well. 3D printing has various applications in different business sectors including engineering, food, chemistry and medicine (Suchubert , et al., 2014). The medical application of 3D printing is rapidly expanding and has numerous application in healthcare sector. It is used in developing hearing devices, dentistry, surgery and medical devices. This incurs a high value in medical applications. The different application of 3D printing in medicine includes customized implants and prosthetics (Ventola, 2014). Furthermore, researches are laid on application of 3D printing in bioprinting. Apart from this, 3D printing can be potentially used for bringing revolutionary changes in the field of healthcare such as in development of surgical cuttings and drill guides, orthopaedic implants and prosthetics. Therefore, it can be said that 3D printing is most valuable for its application in the healthcare (Gibson, et al., 2014). Apart from this, the other applications of 3D printing include structuring complex components for aerospace, automotive and chemical industry. 3D printing has varied application in research industry as well. Researchers use 3D printing in crafting prototypes required for the research. 3D printing has further revolutionized the architecture industry as well. 3D printed houses and building nowadays have become a trend. Therefore, it can be seen that 3D printing has a wide range of application across the different business sectors. Forecast by investment firms With the growing demand and use of 3D printing, the investment firms are keen on integrating 3D printing or additive manufacturing in their business. A 2010 Ganter report identified the 3D printing technology as a transformational technology in the Trigger phase hype cycle (Campbell, et al., 2011). The recent reports and This can trigger the investment firms in taking active interest in this technology to enhance their business processes. This is the reason for which the 3D printing has emerged over broad range of industries in recent times. Researches prove that different companies have capitalized on the products made by integration of 3D printing by taking a manufacturing based approach. 3D printing in making traditional manufacturing obsolete With the increasing use of 3D printing, the traditional manufacturing has taken a back seat. This is because, the technology of 3D printing provides a cost effective solution in a much less time. The process of 3D printing provides some unique advantages over traditional manufacturing (Vaezi, et al., 2013). One of the major advantages of additive manufacturing is that it prevents wastage of materials, as it is a resource efficient approach. The traditional manufacturing methods such as injection mould on a contrary require extra material to fill the mould. Therefore, it is observed that the additive manufacturing process produce much less waste than traditional manufacturing (Lipson Kurman, 2013). Furthermore, the additive manufacturing helps in easy prototype production as it has become very easy to develop a prototype in hours with the help of 3D printing. Therefore, the 3D printing is preferably used for prototyping instead of traditional manufacturing (Berman, 2012). Furthermore , the 3D printing technology allows higher degree of customization of products and development of complex structure that is not possible with traditional manufacturing. Additive manufacturing promotes development of innovative products and increases the speed of marketing new products. The process of traditional manufacturing is complex and time consuming and therefore, there is a high possibility of traditional manufacturing getting obsolete with the advent of additive manufacturing. Furthermore, in the prototypes developed with traditional manufacturing, it becomes very difficult to rework on the same. On the other hand, rework on the prototypes developed with 3D printing is much easier as in case of a rework, a new prototype can be built quite efficiently and in a very less time. Although the use of 3D printing is preferable in rapid prototyping, it is not suitable for high volume manufacturing. This is because, the layer by layer addition of materials becomes very difficult and time consuming for high volume of production. Conclusion Therefore, from the above discussion, it can be concluded that 3D printing is a technology that has varied usage in the different industrial sectors. The different application of 3D printing is discussed in the report. The report evaluates whether additive manufacturing is suited for high and low volume of production. 3D printing is more suitable for low volume of production due to its speed and efficiency. The report further discusses the possibility of 3D printing or additive manufacturing in making the traditional manufacturing obsolete. Although there is an increasing use of additive manufacturing in prototyping, it will take a huge amount of time to replace the process of traditional manufacturing completely. Recommendation 3D printing should be increasingly used in prototyping as it provides a cost effective solution. Small and medium sized manufacturers can integrate the process of 3D printing in their business in order to save time and money in prototyping. Further studies and researchers are required in order to completely replace the process of traditional manufacturing by 3D printing References Berman, B., 2012. 3-D printing: The new industrial revolution.
