In this book, Enterotoxigenic Escherichia coli (ETEC) is described as one of the pathogenic bacteria that is responsible for diarrhoea in human and farm animals. Several fimbrial adhesins of ETEC strains (K88, K99,987P and F41) were used as the primary character of ETEC diarrhoea. Regular dosages of combined K88-K99-987P and K88-K99-F41 through 4 commercial adjuvants: Freund's, White oil, Al(OH)3, and Phosphate Buffer Saline (PBS) were immunised in chickens for IgY antibody production. IgY antibody extraction and purification methods from the eggs were devised. After HiTrap affinity column purification, SDS-PAGE confirmed that the extracted IgY was electrophoretic clean with a molecular weight of 188 kDa. ELISA test indicated that the induced IgYs were 5 titers higher as compared to the non-immunized chickens. The richness of lecithin and cholesterol in egg yolk was found to get the unpurified IgY stable throughout the stomach pH (3-4). Complexed IgY-egg powder (given in-vivo) as a novel food powder could transit the piglet's stomach and had a curative effect against ETEC-inducing diarrhoea.

The protocol developed for IgY purificationindicated approximately 74% recovery rate and 80%purity, while that of ovotransferrin appeared to bearound 93% recovery rate and 80% purity. Theseprotocols seem to be economical and practical for alarge-scale purification of IgY and ovotransferrinfrom chicken egg because ethanol and resin used inthe protocols can be regenerated as well as they aresimple and rapid methods. The combination of 100 mM-NaHCO3 to ovotransferrin was found to bebacteriostatic against E. coli O157:H7 and L.monocytogenes in BHI broth. Also ovotransferrinsolution added with 0.5% citric acid or Zn-boundovotransferrin inhibited the growth E. coli O157:H7and L. monocytogenes in BHI broth respectively.Also, EDTA and lysozyme promoted antibacterialactivity of ovotransferrin solution combined with100 mM-NaHCO3 against E. coli O157:H7 andL.monocytogenes respectively. Based on theseresults, this study claims that ovotransferrincombined citric acid, NaHCO3, and EDTA or lysozymeseemed to be useful antibacterial agents forcontrolling E. coli O157:H7 and L. monocytogenes.

High Quality Content by WIKIPEDIA articles! Chapman served with the Royal Australian Air Force Reserve from 1953 to 1955. He learned to fly (in a Tiger Moth) during Australian National Service. From 1956 to 1957, he worked for Philips Electronics Industries Proprietary Limited in Sydney, Australia. He then spent 15 months in Antarctica with the Australian National Antarctic Research Expeditions (ANARE), for the International Geophysical Year (IGY) as an auroral/radio physicist. The work required that he spend most of the winter with one other man at a remote camp. From 1960 to 1961, he was an electro-optics staff engineer in flight simulators for Canadian Aviation Electronics Limited in Dorval, Quebec. His next assignment was as a staff physicist at the Massachusetts Institute of Technology, where he worked in electro-optics, inertial systems, and gravitational theory until the summer of 1967.

Community Adaptation and Vulnerability in Arcti...

The 'Year' That Changed How We View the North This book is about a new theoretical approach that transformed the field of Arctic social studies and about a program called International Polar Year 2007-2008 (IPY) that altered the position of social research within the broader polar science. The concept for IPY was developed in 2003-2005, its vision was for researchers from many nations to work together to gain cro- disciplinary insight into planetary processes, to explore and increase our understanding of the polar regions, the Arctic and Antarctica, and of their roles in the global system. IPY 2007-2008, the fourth program of its kind, followed in the footsteps of its predecessors, the first IPY in 1882-1883, the second IPY in 1932-1933, and the third IPY (later renamed to 'International Geophysical Year' or IGY) in 1957-1958. All earlier IPY/IGY have been primarily geophysical initiatives, with their focus on meteorology, atmospheric and geomagnetic observations, and with additional emphasis on glaciology and sea ice circulation. As such, they excluded socio-economic disciplines and polar indigenous people, often deliberately, except for limited ethnographic and natural history collection work conducted by some expeditions of the first IPY. That once dominant vision biased heavily towards geophysics, oceanography, and ice-sheets, left little if any place for people, that is, the social sciences and the humanities, in what has been commonly viewed as the 'hard-core' polar research.

Coleman, D: Big Ecology - The Emergence of Ecos...

ggf. zzgl. Versand

In 'Big Ecology,' David C. Coleman documents his historically fruitful ecological collaborations in the early years of studying large ecosystems in the United States. As Coleman explains, the concept of the ecosystem--a local biological community and its interactions with its environment--has given rise to many institutions and research programs, like the National Science Foundation's program for Long Term Ecological Research. Coleman's insider account of this important and fascinating trend toward big science takes us from the paradigm of collaborative interdisciplinary research, starting with the International Geophysical Year (IGY) of 1957, through the International Biological Program (IBP) of the late 1960s and early 1970s, to the Long-Term Ecological Research (LTER) programs of the 1980s.

Althoff, W: Artic Mission

To help salve the sting of orbiting Sputniks, the United States needed a dramatic demonstration of technological prowess; early in 1958, the White House ordered a top secret under-ice transit of the Arctic Ocean--Pacific to Atlantic--via the North Pole. And that spring, the Office of Naval Research initiated a unique project: to assess whether non-rigid airships (blimps) could support field parties deployed in the Arctic. This book recounts two successful missions. In August, the nuclear submarine Nautilus (SSN 571) reached 90 North and, continuing under ice, logged the first deep-ocean transit of the basin. En route to rendezvous with an IGY drifting station on T-3, an ice island, U.S. Navy airship BUNO 126719 became the sole military airship to cross the Arctic Circle. This work is based on first-hand accounts, including journal excerpts from Dr. Waldo Lyon a force behind U.S. under-ice submarine development
