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.

IgY An Alternative antibody. This text book gives a clear illustration and description of the principles and concepts of immunology in a highly accessible and comprehensive manner. This book is designed to cater the basic needs of the scientists in the field of Biomedical science, Biotechnology, Immunology, Biochemistry and Microbiology. This book also elaborates and highlights the various techniques employed for in vivo and in vitro analysis of biomolecules. Each chapter starts with introductory details of the techniques followed by laboratory methods. The book is compartmented into five following chapters, 1. Introduction 2. Venom composition and enzyme activities 3. Symptoms, signs and treatment of cobra bite 4. Extraction of egg yolk IgY 5.In vivo and In vitro assays.
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
In diesem Buch wird enterotoxigene Escherichia coli (ETEC) als eines der pathogenen Bakterien beschrieben, das für Durchfallerkrankungen bei Menschen und Nutztieren verantwortlich ist. Mehrere Fimbrienadhäsine von ETEC-Stämmen (K88, K99,987P und F41) wurden als primärer Charakter von ETEC-Durchfall verwendet. Regelmäßige Dosierung von kombinierten K88-K99-987P und K88-K99-F41 durch 4 kommerzielle Adjuvantien: Freund's, Weißöl, Al(OH)3 und Phosphatpuffer-Salzlösung (PBS) wurden bei Hühnern zur Produktion von IgY-Antikörpern immunisiert. Es wurden Methoden zur Extraktion und Reinigung von IgY-Antikörpern aus den Eiern entwickelt. Nach der Reinigung der HiTrap-Affinitätssäule bestätigte SDS-PAGE, dass das extrahierte IgY elektrophoretisch sauber mit einem Molekulargewicht von 188 kDa war. Der ELISA-Test zeigte an, dass die induzierten IgYs 5 Titer höher waren als bei den nicht immunisierten Hühnern. Der Reichtum an Lecithin und Cholesterin im Eigelb führte dazu, dass das ungereinigte IgY im gesamten pH-Wert des Magens stabil war (3-4).
The research was aimed to study the potential of probiotic lactic acid bacteria as suitable alternatives to antibiotics in broilers. This was design to find a possible replacement to antibiotics in broiler production. The study was carried out at the Department of microbiology, faculty of sciences Kaduna State University, Kaduna between January to May 2018. A total of ten raw milk samples were screened for the isolation of Lactic Acid Bacteria and 20 day-old broiler chicks (initial body weight 41 ± 0.5 g) were administered probiotics containing Lactobacillus fermentum, Lactobacillus plantenrun and Weissalla ciberia in water at 108 cells/milliliters/isolates/birds/day at day 6, 7, 8, 21, 22, and 23 of ages. Body Weight (BW), Weight Gain (WG) and Feed Intake (FI) were measured weekly just as feed conversion ratio was calculated and mortality recorded throughout the duration of the experiment. Blood glucose concentration, total protein, lipid profiles and Total immunoglobulins (IgY) were determined from blood sample at the ages of 14 and 42 days. Carcass quality and proximate analysis were evaluated from the meat of the broiler at the age of 42 days.
It has become increasingly clear that the magnetosphere becomes intermittently unstable and explosively releases a large amount of energy into the polar upper atmos phere. This particular magnetospheric phenomenon is called the magnetospheric sub storm. It is manifested as an activity or disturbance ofvarious polar upper atmospheric phenomena, such as intense auroral displays and X-ray bursts. Highly active conditions in the polar upper atmosphere result from a successive occurrence of such an element ary activity, the polar substorm, which lasts typically of order one to three hours. The concept of the magnetospheric substorm and its manifestation in the polar upper atmosphere, the polar substorm, has rapidly crystallized during the last few years. We can find a hint of such a concept in the term 'polar elementary storm' introduced by Kristian Birkeland as early as 1908. However, we are greatly indebted to Sydney Chapman, who established the basic foundation of magnetospheric physics and has led researches in this field during the last half century. Indeed, the terms 'polar magnetic substorm' and 'auroral substorm' were first suggested by Sydney Chapman. The concept of the substorm was then soon extended by Neil M. Brice of Cornell University, and Kinsey A. Anderson and his colleagues at the University ofCaliforrlia, Berkeley, who introduced the term 'magnetospheric substorm'. We owe many of these recent developments in magnetospheric physics to the great international enterprise, the International Geophysical Year (IGY) and subse quent international cooperative effort (IGC, IQSY).

V. 2008 The Sun-Earth Connection is now an accepted fact. It has a signi cant impact on our daily lives, and its underpinnings are being pursued vigorously with missions such as the Solar TErrestrial RElations Observatory, commonly known as STEREO. This was not always so. It was not until the middle of the nineteenth century that Edward Sabine connected the 11-year geomagnetic cycle with Heinrich Schwabe&#8217;s deduction of a like periodicity in the sunspot record. The clincher for many was Richard Carrington&#8217;s sighting of a great whi- light are on the Sun, on September 1, 1859, followed by a great geomagnetic storm 18 hours later. But was the Sun-Earth Connection signi cant to terrestrial denizens? Perhaps in 1859 it was not, but a century later it became so. Beginning in the 1930&#8217;s, as electrical powergrids grew in size, powercompanies began to realize that they occasionally had power blackouts during periods of intense geomagnetic activity. This correlation did not appear to be suf ciently signi cant to bring to the attention of the public but during the International Geophysical Year (IGY), when geomagnetic activity was being scrutinized intensely, the occurrence of a large North American power blackout during a great magnetic storm was impossible to ignore.
