Antimicrobial Potency Of Silver Nanoparticles - 1691 Words

Abstract Bacteria have long since existed alongside humans, and while some are not harmful, there are many that are. Plants are commonly used natural remedies for diseases, and have been known to retain immense antibacterial properties that can fight bacteria. Silver nanoparticles have been also known to possess antimicrobial properties that aid in the fight against various bacteria. The use of plants as well as silver nanoparticles to fight against bacteria has caused much interest in the nanotechnology and medicine fields, and has been the basis of many studies. The purpose of this paper is to scrutinize the antimicrobial potency of silver nanoparticles, and how they may be utilized to fight against various harmful bacteria. Bacteria: The Antimicrobial Potency of Biosynthesized Silver Nanoparticles against It Bacteria are found all over the world in all types of regions and climates, and can also exist within other organisms (â€Å"Bacteria,† n.d.). Bacteria make up a large portion of the population of prokaryotic organisms that coexist with us (â€Å"Bacteria,† n.d.). As technology has evolved and our understanding of these organisms has increased, it has come to the attention of many in the scientific community that there is a significant amount of bacteria that live symbiotically within organisms such as humans (â€Å"Introduction to the Bacteria,† n.d.). As a matter of fact, human beings rely on bacteria to live. There are bacteria known as actinomycetes, that have beenShow MoreRelatedConcurrent To The Backlash Against Parabens, There Has1618 Words   |  7 Pages1800s and they are well known for their antimicrobial properties (Scher).

Visual Literacy And The Arts In Essay Example For Students

Visual Literacy And The Arts In Essay Students acquire the necessary skills to understand the meaning in texts and be able to produce their wan puissant writing as well. Arguments concerning literacy are centered almost exclusively on written text and this is the only definition of literacy in which most are exposed to. However, we live and work in a visually oriented society in which the idea of being visually literate remains extraneous to the mainstream definition of an educated person. Our current culture is one in which we are subjected daily to images in every form, and over- saturated with pictorial advertising, both informative and misleading, The importance of visual literacy as an important aspect of critical hinging in present times becomes clear in the tact of such prolific output. It has been traditionally placed in the realm of fine arts, taught as a component of art and, specifically, design. The popular mode of thought is that one either has some artistic talent that includes visual literacy or does not, but it is rather a skill that can be taught, much like reading. Visual literacy should be an integral part of a modern education and it should be central to the contemporary definition of literacy. It is estimated that almost half of the knowledge we acquire is through usual means, pointing to its relevance beyond traditional art education (Karakul When budget cuts become necessary, schools often mark arts programs as the first to be cut. They regard education for the humanities as an extravagance that is not so important even money is scarce, yet financial constraint is not the only threat. In our current education system, school curricula are designed around state mandated tests. It is no wonder then that time dedicated to arts education and visual literacy is often seen as time taken from more important studies, specifically those that states test for. With strict limits on time and money, visual literacy and education for the arts has become a luxury that schools cannot or will not afford. The idea that arts education is only a frivolity isnt new. Booker T. Washington argued that only once the African. American community had begun to achieve a certain prosperity should the arts be added to their education (Washington 17). Nevertheless, the concept that visual literacy is inessential to an effective education ignores the preponderance of art, visual communication and the necessity of visual literacy. The earliest known paintings and drawings are roughly 14,000 years old. Prosperity, it would seem, is not a precondition for a culture to rich visual communication. Rather than supporting visual literacy and arts education, though, the ubiquity of the arts and visual forms can as a logical argument against it. If people are making art regardless of their education and economic stature then why should schools devote time and money teaching it? Why not just let art, design, and the understanding of it happen as it will? We are surrounded daily by pictures both informative and aesthetic in a vast number of forms, therefore visual literacy will come on its own, perhaps through experience or simply chance. If this is considered a sound argument against teaching art, then it is equally logical to argue against teaching language. Kids can learn a language simply by growing up around people that speak it fluently. However, nobody has argued that we ought to let nature take its course and drop the study Of English from our schools for the sake Of saving money. We can appreciate how modern education improves the capability to read, write and speak effectively, yet schools do not give visual literacy the same consideration. Skepticism concerning the feasibleness of art education is bound in the false action that art cannot be taught. .u783b3fe53a9b441043d217801e6bbaf9 , .u783b3fe53a9b441043d217801e6bbaf9 .postImageUrl , .u783b3fe53a9b441043d217801e6bbaf9 .centered-text-area { min-height: 80px; position: relative; } .u783b3fe53a9b441043d217801e6bbaf9 , .u783b3fe53a9b441043d217801e6bbaf9:hover , .u783b3fe53a9b441043d217801e6bbaf9:visited , .u783b3fe53a9b441043d217801e6bbaf9:active { border:0!important; } .u783b3fe53a9b441043d217801e6bbaf9 .clearfix:after { content: ""; display: table; clear: both; } .u783b3fe53a9b441043d217801e6bbaf9 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u783b3fe53a9b441043d217801e6bbaf9:active , .u783b3fe53a9b441043d217801e6bbaf9:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u783b3fe53a9b441043d217801e6bbaf9 .centered-text-area { width: 100%; position: relative ; } .u783b3fe53a9b441043d217801e6bbaf9 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u783b3fe53a9b441043d217801e6bbaf9 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u783b3fe53a9b441043d217801e6bbaf9 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u783b3fe53a9b441043d217801e6bbaf9:hover .ctaButton { background-color: #34495E!important; } .u783b3fe53a9b441043d217801e6bbaf9 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u783b3fe53a9b441043d217801e6bbaf9 .u783b3fe53a9b441043d217801e6bbaf9-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u783b3fe53a9b441043d217801e6bbaf9:after { content: ""; display: block; clear: both; } READ: Erich Fromm and Shirley Jackson have both written wonderful true-life affecting essays and should be awarded for themTalent is a gift, something that a number of people are simply horn with, and art results from inspiration. Coinciding with these ideas is the concept that art appreciation is entirely subjective, a matter of however art makes the viewer feel. If these stereotypes were true, education could not do much tort the development to creative people or their audience. Nor could it teach young minds how to make sense of the visual information they are subjected to on a near constant basis. The misconception lies in the idea that education consists exclusively in the transfer of information and ends there, Since art is not strictly propositional, it must not contain verifiable truths or facts, and since most art does not present any arguments, or at least in an easily recognizable fashion, it must not require justification. Works of art then have very little, if any, credible data to convey. Construed as sources of information, Mary Motherless writes, the arts create a poor showing; as a means of acquiring nevi truths about the world or the soul, they are in competition with science and with philosophy (8). While inspiration certainly figures in the creation of art, the idea that art is entirely a product Of inspiration is unwarranted. Within the visual arts, students learn the powers and limitations of the various media available, as well as the effects Of color, light, shade, shape, and form. Further, artists benefit greatly from studying art history. Even if creative talent is a genetic gift, education can foster and develop those creative skills and the level of critical thinking needed to use those skills effectively. Regardless of the fact that most people will never be artists in the traditional sense, and comparatively ewe people will even be serious amateur artists, we are all part of a greater audience. Audiences of the humanities do not consist entirely of cultural elite. They embody everyone who watches TV, goes to the movies, reads the news or uses the internet. Indeed we are bombarded with visual stimuli continuously. Information graphics are everywhere we look, Visual literacy is worth it for its own sake, however it also provides a platform for understanding both of art and other matters as well. Through an education that includes visual literacy we can develop perspectives that allow us to raise questions that, without them, e might not have. It is also important to note that visual literacy and the arts in education can cultivate a demand for art that is economically essential. Data from the National Endowment for the Arts Survey of Public Participation in the Arts shows evidence of a chronic decline in the audience (Karakas 27). Equally as worrying is the steady decline of young adult participation. As the authors of, Cultivating Demand for the Arts, Arts learning, Arts Engagement, and State Arts Policy declare, declining demand leads to a loss of the public and private benefits derived from the arts (27).

ECONOMICS - Essay Example An organization will have to pay higher interest coverage for their long term debts. In addition to this, the charges for bank overdraft and short term borrowings will rise which will affect the working capital balances adversely. If the company has leased manufacturing instruments, it will have to pay a higher lease rental. Since an increase in the interest rates will tend to squeeze money out of the economy, employees might demand higher salaries as well. According to Bloomberg, the yield curve (as on May 8, 2009) predicts the rise of interest rate in near future. This means that organization will plan to maintain its profit in future. It can provide discounts to enhance the sales volume to make reserves for the dry season ahead. It can restrict research and development activities and curtail unnecessary costs since revenue generation might see a downfall. Cars and trucks are costly commodities and are generally bought by customers if they get convenient borrowing schemes. This makes interest rates a decisive factor in determining the sales. A high interest rate means that customers will have to pay a higher installment (EMI). This has greater implications for earning assets like trucks; customers (generally transporters) will postpone their present demand in anticipation of lower interest rates in future. This translates to the fact that consumer demand for both cars and trucks will come down. The main monetary items that affect the operations of a business are the cost of goods sold and general and administrative expenses. Cost of goods sold will depend on the cost of raw materials and the wages of the employees. The company might have to incur advertising and selling costs as well.

Differences in social relationships on the Internet and conventional, Essay

Differences in social relationships on the Internet and conventional, face to face relationships - Essay Example However, the human need to be connected to others is always present, and so people have turned to the internet, specifically, some social networking sites and applications to fulfill this need in the midst of their busy schedules, as family and friends have become more accessible and available in just a click of a button. It also offers a myriad of opportunities for meeting more people, relaxing with online games, sharing pictures and videos and an outlet to express innermost thoughts and feelings to share with others. McCown et al. (593) conducted a study about people who meet people via the internet and found that in general, they tend to be truthful in their interactions although they initially did not reveal their true names and were careful about their anonymity. Eighty percent of the subjects of the study formed casual or friendly relationships while 6% formed intimate or romantic relationships. About a third of the subjects made offline contact with 40% conversing by phone and 33.3% actually meeting in person. It was also found that people who established friendships on the internet take appropriate precautions to protect their identities but find the medium a safe and effective way to interact with others and to expand one’s social circle. Some people, though, have kept private information about themselves private before getting involved in social networking sites. They go on their lives keeping things to themselves, or have the option to share them with others by verbally divulging such information. Control of information is greater and confidentiality is better assured under the shield of anonymity. In another study by Stephure et al. (658) on online dating and engaging in romantic relationships via the internet, it was found that involvement in online dating increases rather than decreases as people get older due to their diminishing satisfaction with conventional establishment of romances. The internet has become a convenient method of findin g a potential life partner. Stafford, Kline and Dimmick (662) remark that technology users think they can maintain relationships online especially those they have developed offline initially. At the time of their study (in the nineties) when video chat was not yet available, small and quick emails were used to keep in touch as opposed to letter writing. They also comment that some people tend to treat interactions with computers as social encounters so unconsciously, they also expect the rules of social interactions formed offline to also apply online. Colgate and Smith (140) have studied business relationships maintained online and found that the mode of interaction makes little difference to the strength of the relationship. Trust is established in the existence of good one-to-one relationship with the business partner. They also found that â€Å"the effects of the relationship banker are dependent on whether the customer uses primarily the branch versus the internet† (Colg ate and Smith, 40). With the coming of Facebook, old friends have been reunited, families have grown closer, and people have been updated with each other’s lives. Writing one’s status message helps keep others aware of the state of emotions or life situation a particular friend is in and may write their own comment to show support, or mere acknowledgement of
