Fundamentals of Chromatography

Chromatography is a science of study that involves the separation of molecules in a mixture based on differences in their structure and/or composition. It is one of the most common physical methods performed in laboratories to separate the most complex mixtures containing complex molecules. The procedure consists of two parts viz. the mobile phase and the stationery phase. The mobile phase is the mixture to be separated dissolved in a solvent and the stationery phase is the layer of a certain material in its solid form through which the mobile phase passes through and disintegrates into separate components at various stages. Adsorptive materials are used in the stationery phase.

If you notice the functions of chromatography procedure you would know what exactly it is useful for. Its application implies on to chemical or bioprocessing industries where they are faced with the challenge to separate and purify from a complex mixture a particular compound that forms an important factor in the production line. The method is so precise that it can even successfully separate proteins that vary in a single amino acid from a complex protein mixture. Also the conditions under which chromatography is performed are not severe thus it can be used to separate products with higher sensitivity as well.

Does A Horse Whisperer Have An Animal Science PhD?

As humans do not live on sunshine and water, we all need to consume some form of agricultural products. Depending on your choice in sustenance, they comprise plant or animal life, or both. Advancement in technology has brought about a new qualification in animal science which focuses primarily on the study of domesticated animals such as cattle, sheep, swine, horses and such. Obtaining an animal science PhD normally requires in-depth study into animal management in the world of agriculture.

In order to apply and be accepted into a doctorate program in animal science, it’s important for the applicant to have the necessary tertiary qualifications. In addition, prior work experience with animals is certainly an advantage as it may be impractical to pursue a PhD if you’re green behind the ears. For example, if you want to get an animal science PhD in animal husbandry, it is beneficial to have worked in an environment which raises and breeds livestock. By learning and understanding the fundamental elements, it makes it easier to grasp the complex matters.

As opposed to other PhD programs which are offered via online channels or as distance learning packages, pursuing this form of doctorate qualification requires hands-on experience. A lot of time is spent learning and observing lives of the animals, their physical and biological characteristics with the occasional psychological part. Apart from lecture halls and study groups, a fair amount of research constitutes coursework for an animal science PhD student. There’s no better place to do research than being on the ground, handling the animals in their native settings.

Carl Sagan – A Life In The Cosmos

It’s incredible to think that it’s more than fourteen years since the world lost a most remarkable astronomer, pioneer exobiologist and populariser of science – Carl Sagan.

A son of Jewish immigrants to the United States, Sagan was born in Brooklyn, New York, where he spent his childhood developing an interest in astronomy. A high achiever, he studied physics at the University of Chicago, gaining a master’s degree in 1956, before being awarded a doctorate there in 1960 in astronomy and astrophysics. He then lectured at Harvard University until 1968, when a move to Cornell University in Ithaca, New York beckoned. In 1971 this became a full-time professorship that included the directorship of the Laboratory for Planetary Studies. He also took an increasing interest in pioneering exo-biology and publicising the Search for Extraterrestrial Intelligence (SETI). During this period, he also became an Associate Director of the Centre for Radio Physics and Space Research at Cornell, and later was instrumental in lecturing at Cornell in scepticism and critical thinking.

Such an academic career would have been amazing in itself, but Sagan had been heavily involved in the US space program since the 1950s — including his celebrated briefings of the Apollo astronauts before their flights to the Moon. However, of utmost interest to this most talented of scientists was planetary science and the increasing number of NASA robotic missions to neighbouring planets in the solar system. Indeed, he was responsible for many of the biology and chemistry laboratory packs placed on these unmanned probes. He also gained worldwide attention for his idea of placing gold-anodised unalterable universal messages, onto unmanned spacecraft destined to leave our solar system. These included Pioneer 10 and 11, launched in 1972 and 1973 respectively. In the albeit slim hope of these emissaries of mankind one day millions of years from now being located by extraterrestrial intelligence, the plaques were developed further, and along with the Golden Record of sounds of the earth, were again attached to the Voyager unmanned probes launched to investigate the outer solar system in 1977.

Science And Technology Current Affairs

Renaissance brought along new ideas, beliefs as well as challenges for the people. Things based on faith and belief gave way to reason and understanding. That was not only the introduction of novel ideas but also the beginning of a new standard of science and technology. Science is based on facts and has no room for superstitions. At present, science and technology is a field, which is growing tremendously. News is a medium, which helps us get information regarding the current affairs of India.

Due to advancement in science and technology, the world has become closer and the feeling of togetherness is stronger. Everywhere you look, you see technology. One of the best inventions of the science and technology sector is the invention of computers. This has brought the people sitting millions of miles away very closer to you. Even cell phones are a blessing. There are millions of things based on technology and the number is increasing with every passing minute. It has made the life of people so much easier. If we visualize the world after 15 years or so, it would be run by remote controls. Such is the magic of science that we can sit at home and know about the person sitting at the other end of the world, without much difficulty. The best part about his is, that it is not confined to metropolitan cities. Even though villages are still lagging far behind but one cannot say that, they are untouched by technology.

Every day in the newspaper, we see a new invention or a discovery by the scientist. Even cures have been found for diseases, which were earlier considered fatal. Current affairs section is filled with such discoveries and the on going projects related to science and technology.

Technology Education About Life Science

In Mav 2000, Matthew Meselson, an issue related to biological weapons, leading figure in the life sciences on issues related to biological weapons, offered a warning at the annual meeting of the U.S. National Academy of Sciences. Every major technology-metallurgy, explosives, aviation, electronics, nuclear energy has been internal combustion, intensively exploited, not only for peaceful purposes but also with biotechnology, certain to for hostile ones. Must this also be a dominant technology of the next century? During the century just modify fundamental life processes continues its rap in, as our ability to aid advance, we will ways to destroy life but will also be able to manipulate it including the processes of cognition, development, reproduction, and inheritance. A world in which these capabilities are widely employed for hostile purposes would be a world in which the very nature of conflict has radically changed.

Therein could lie unprecedented opportunities for violence, coercion, repression, or subjugation. Concerns about the potential security risks posed by life sciences research can be seen in the context of rising concerns and sometimes ty sharp disagreements about the more general risks of weapons of mass destruction (WMD), including biological weapons and bioterrorism, following the end of the Cold War (see, for example, Carter, Deutch, and Zelikov 1998). More specifically, a number of articles in scientific journals early in this decade sparked controversy about whether the risks cited by Meselson were already present, with critics charging that the publications could provide a “blueprint” or “roadmap” for nations or terrorists.?

The Undergraduate Education Of Life Science Majors

The ideas presented here for transforming the undergraduate education of life science majors are demanding, but the committee believes that significant change is realizable within this decade if these recommendations are acted upon. Reform will require concerted action by faculty, administrators, professional societies and other educational organizations, foundations, industry, and government. The process begins with faculty and administrators. The committee urges each academic institution to critically review how it educates its future biologists. Departmental retreats are a good setting for an initial examination of current educational objectives, practices, and outcomes. The circle should eventually be broadened by inviting faculty from different departments to come together with administrators and discuss aspirations and goals for the coming decade. The resources needed to effect these changes must be clearly defined and a realistic path must be charted to complete the planning stage.

University administrators will need to actively support faculty development and remove barriers to interdisciplinary teaching, a key aspect of enhancing undergraduate education. Departments and colleges must find new ways to help individual faculty and academic departments innovate and reward their efforts in creating, assessing, and sustaining new educational programs. For example, faculty interested in adapting teaching approaches for their own use or in creating new teaching materials should have lighter than normal requirements for teaching, research, or service while actively engaged in such projects. Also, travel funds earmarked especially for faculty development or education meetings should be provided to enable faculty to participate in meetings that enhance their teaching capabilities.
