Sensor Technology For Water Quality Monitoring

RRP $54.95

Two methods for the detection of important human pathogens, Cryptosporidium parvum and Helicobacter pylori, were investigated: a fiber optic biosensor, and real time PCR. The mechanism for specific detection in both methods is recognition of specific DNA sequences in the target organisms. The biosensor that was used, the Analyte 2000, was originally developed for the detection of chemicals. It utilizes a fiber optic wave guide that propagates an evanescent light wave of very specific wavelength. The light excites fluorescent molecules bound to the waveguide, but not in the bulk solution, which theoretically enhances signal while reducing background interference. Attempts to develop this system for the detection of DNA were not successful due to poor detection of the target molecules. An assay analogous to a sandwich immunoassay was designed for use on the Analyte 2000. Specific oligonucleotide probes were designed to bind to the waveguides via biotin-streptavidin interaction, and were used to capture the target DNA. Pure target DNA representing unique genes in the organisms were synthesized by PCR. Detection of captured DNA was then attempted using an oligonucleotide detection probe designed to bind to the target. Two detection systems were employed: an indirect signal amplification system based on biotin-tyramide deposition, or direct detection of fluorescent signal from Cy-5 molecules. In all experiments performed there was very little difference between the signal generated with or without the target molecules. Many experiments were conducted to attempt to identify reasons for the poor signal. Signal was only of any significance when target amplicons were internally labeled with Cy-5 by PCR. Real time PCR as a method to detect the pathogens was also investigated. Though the PCR technique itself is very rapid, DNA extraction and purification requires preparation time. Filtration of up to one liter of well water, followed by concentration and "cleaning" Helicobacter pylori cells by immunomagnetic separation, was used to detect H. pylori seeded in a water source. Following cell lysis, the extracted DNA could be used directly in conventional PCR targeting the 16S rRNA gene to detect less than 265 cells per liter of water. DNA purification was not required for this level of detection. Initial studies to amplify lysed cells by real time PCR indicated that an incorrect product was made. When purified DNA was used for real time PCR, the correct product was produced from DNA representing as few as 100 cells.

Applied Biophysics Of Activated Water

RRP $338.99

This book provides a detailed review of the modern theories dealing with the structure and properties of water. It also presents an analysis of the research on the effect of activated water on biological systems such as animals, microorganisms, and plants. The results of experiments on the influence of activated water on "pure" microbiological cultures and their natural associations are described, the studies being carried out under both aerobic and anaerobic conditions.The results demonstrate a significant influence of activated water on higher plants (vegetable crops), sterile plants, and callus tissues. It is shown that the activation of water under definite conditions gives rise to the appearance of very strong bactericidal properties: activated water inhibits the development of pathogenic microbiological cultures by tens and hundreds of times more strongly, and can be used for sterilization. In addition, a potent positive effect of activated water on the prevention and treatment of cancer in mice has been observed, and its efficacy compared to that of chemotherapy is discussed in the book.The information provided in this book is supported by intensive experimental data and developed theories. The research programs were conducted at the authors' laboratories in Ukraine and Russia as well as at research facilities located in the USA.


Water And Ions In Biological Systems

RRP $32.00

As the First International Conference on Water and Ions in Biological Systems (Bucharest, June 25-27, 1980) was appreciated as a success, a second one was organized in the fall of the year 1982 under the sponsorship of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Romanian Academy of Medical Sciences, the Romanian Biophysical Society (Union of Societies for Medical Sciences in the Socialist Republic of Romania) and in co- operation with the International Union for Pure and Applied Bio- physics (IUPAB). The responsibility for the scientific program and organization of the Second Conference on Water fell on an International Scientific Committee which included Prof. J. Tigyi (Pees), President of the UNESCO Expert Committee on Biophysics, Prof. K. Wuthrich, Secretary General of IUPAB and Prof. H. Eisenberg, (member of the IUPAB Council) under the guidance of an Executive Board whose members were Prof. J. Jaz (representative of UNESCO), Prof. B. Pullman (Vice- President of IUPAB) and Prof. V. Vasilescu (President of the Romanian Biophysical Society). The Meeting was attended by more than 250 specialists including 150 Romanian participants and others from Bulgaria, Czechoslovakia, England, the Federal Republic of Germany, the German Democratic Republic, Greece, Hungary, India, Israel, Italy, Japan, the Netherlands, Nigeria, Poland, Sweden, Switzerland, USSR, USA, Venezuela, Yugoslavia. The proceedings of the Conference took place in the Medical Faculty of Bucharest. The theoretical and practical importance of the Meeting was pointed out by the speakers, among whom were Prof.


Pure Trash

RRP $12.99

The year is 1955. Experience the joy of a carefree Saturday and the blistering pain of feeling not quite good enough as you hop on a bike and ride into town with two delightful young boys who find adventure at every turn. Shawn and Willie Daniels live in the woods with no indoor water or plumbing. Dad spends most of his hard earned money on beer. Prejudice, class division, alcoholism, poverty, injustice, and a hint at bullying are cleverly woven into this 1950s adventure short. PURE TRASH is a prequel to the author's upcoming debut novel.


Jimmy Carter And The Water Wars

RRP $305.99

"So much of the literature on presidential influence on congressional voting relies on assertions and assumptions about presidential influence in Congress. This study measures actual presidential influence on a member by member basis. The discovery of the White House records on presidential calls to House members adds a whole new level of depth to our understanding of how the relatively unpopular Carter won those floor votes. This work adds broadly to the dynamics of presidential leadership in Congress. Jimmy Carter and the Water Wars makes a real contribution to the literature on presidential influence in Congress." - Lance T. LeLoup, Edward R. Meyer Distinguished Professor of Political Science, Washington State University "Do you want to know how Washington really works? Read Frisch and Kelly's excellent and well-researched chronicle Jimmy Carter and the Water Wars. They bring to life the events surrounding a critical turning point in the Carter Presidency. This is required reading for anyone interested in presidential leadership in Congress." - Representative Butler Derrick, (D-South Carolina, retired) "Part political history, part political science, this engaging book does both well. Jimmy Carter and the Water Wars is an important addition to our understanding of the Carter presidency. It sheds new light on Carter's legislative leadership and, by focusing on the politics of pork, serves as a backdrop to ongoing debates over congressional expenditures. Combining qualitative and quantitative analysis, Frisch and Kelly not only tell a great story, but also systematically analyze the effect of Carter administration efforts to lobby members of Congress. The result is an important study of presidential influence in Congress." - John Anthony Maltese, Albert Berry Saye Professor of Political Science, University of Georgia
