Molecular Microbiology of Heavy Metals (Microbiology Monographs) Description

All forms of life depend on a variety of heavy metal ions. Nearly one-third of all gene products require a metal ion for proper folding or function. However, even metals generally regarded as non-poisonous are toxic at higher concentrations, including the essential ones. Thus, sensitive regulation of metal uptake, storage, allocation and detoxification is needed to maintain cellular homeostasis of heavy metal ions.

Molecular Microbiology of Heavy Metals includes chapters on allocation of metals in cells, metal transporter, storage and metalloregulatory proteins, cellular responses to metal ion stress, transcription of genes involved in metal ion homeostasis, uptake of essential metals, metal efflux and other detoxification mechanisms. Also discussed are metal bioreporters for the nanomolar range of concentration and tools to address the metallome. Chapters in the second part cover specific metals such as Fe, Mn, Cu, Ni, Co, Zn and Mo as key nutrient elements and Ag, As, Cd, Hg and Cr as toxic elements.

Organic Chemistry - Textbook Only Description

With a reputation for outstanding scientific quality, Organic Chemistry by G. Marc Loudon is a textbook that students will actually want to read. This much-anticipated fourth edition continues its predecessors' popular and unique mechanistic approach within a functional group framework. Enhanced biological and biochemical material make it ideal for chemistry majors as well as premedical and prepharmacy students taking a full-year, sophomore level course. Loudon's excellent use of language and reader-friendly style transform organic chemistry into a logical, understandable, and exciting subject for students. In use at undergraduate and graduate schools of all levels, this authoritative yet accessible volume is packed with effective analogies that enliven and clarify rigorous discussions of important concepts. For example, Loudon uses a flute player jumping between musical octaves to explain transitions between quantum levels. An engaging detective with combined characteristics from Sherlock Holmes and James Bond depicts resonance structures. Thanks to humorous characters like Flick Flaskflinger and Professor Havno Scentz, problem solving becomes simultaneously challenging and entertaining. Varying from the routine to the complex, Loudon's problems are renowned for their originality, their range of difficulty levels, and their ability to teach students to understand and predict organic reactivity rather than just memorize facts. In addition, Loudon blends biological, environmental, and industrial applications of organic chemistry into the body of the text--rather than separating them as "special topics"--giving students an integrated sense of the subject in its real-life context.

Emerging Organic Pollutants in Waste Waters and Sludge (Handbook of Environmental Chemistry) Description

Over the past fifteen years regulatory agencies have relied on their approaches to characterise and control the release of toxic substances into the aquatic environment: a GC/MS analysis for U.S. EPA designated 126 priority pollutants and 132 dangerous substances according to the European 76/464/CEE Directive and on the bioassays with aquatic bioorganisms.
"Emerging Contaminants" correspond in most cases to irregulated contaminants, e.g. surfactants, pharmaceuticals and personal care products (PPCP), or gasoline additives.
These two volumes, 5/I and 5/O, of this Handbook deal with the analytical, toxicological and environmental issues of these toxicants. Based on results of up-to-date research they give the reader a balanced view on this rapidly developing and complex subject.

The Usborne Illustrated Dictionary of Science (Usborne Illustrated Dictionaries)

Customer Shopping BuZZ

Excellent for many topics
This book gives a simplified explanations for many topics in science. It covers biology, chemistry, and physics. It also includes detailed drawings for many topics. The explanations are simple enough that many 8th graders are able to understand them. As a science teacher I love this book. I makes rewording topics for students to understand a breeze. It was also a good refresher for any topics I hadn't studied in a while.

One of the best books I've ever owned
My parents bought me this book in hardcover about ten years ago, and it has been indispensible. It covers a broad enough base of information so well, and with enough depth, that it has been a constant and indispensible reference for me through GCSE science in the UK, high school chemistry in the US, and even sometimes during my undergrad chemistry and physics. The illustrations are wonderful, and the explainations lucid. I would definitely recommend this for anyone with a child in school, or anyone who wants to look at a bit of basic science.

Absolutely brilliant.
About 15 years ago, as a 9 year old, I read the three books that make up this Dictionary of Science (the Biology, Physics and Chemistry ones). I was completely captivated by them, and read them over and over again. The science is pitched at exactly the right level for children: the colourful illustrations and short sections retain a child's attention. I went on to take biology, physics and chemistry A-levels at age 17, and went on to study Medicine at Cambridge University in England. Obviously there was more to this achievement than the Usborne books I read as a child, but I honestly do attribute much of my initial interest to them.

Medical Statistics from A to Z: A Guide for Clinicians and Medical Students Description

From 'Abcissa' to 'Zygosity determination' - this accessible introduction to the terminology of medical statistics describes more than 1500 terms all clearly explained, illustrated and defined in non-technical language, without any mathematical formulae! With the majority of terms revised and updated and the addition of more than 100 brand new definitions, this new edition will enable medical students to quickly grasp the meaning of any of the statistical terms they encounter when reading the medical literature. Furthermore, annotated comments are used judiciously to warn the unwary of some of the common pitfalls that accompany some cherished biomedical statistical techniques. Wherever possible, the definitions are supplemented with a reference to further reading where the reader may gain a deeper insight, so whilst the definitions are easily disgestible, they also provide a stepping stone to a more sophisticated comprehension. Statistical terminology can be quite bewildering for clinicians: this guide will be a lifesaver.

Spectroscopy

When a sample is illuminated with broad-band white light some of this energy may absorbed at discrete wavelengths by constituent molecules. The measured deficiencies in exiting energies can provide the identifying 'finger print' of the constituent molecule. In the NIR region the observed absorption bands are either overtones or combinations of overtones of fundamental bands originating in the mid infrared region (2500 to 25000 nm).

These overtones and combination bands are much weaker (typically by a factor 1000) than their counterparts in the IR region and characteristically have broad bandwidths ">(typically 30-40 nm FWHM). Low absorptivity in the NIR allows the use of long path lengths and making for minimal or no sample preparation; a significant advantage for in-line analyses.

Some typical spectra show the need to use chemometrics.

The potential role of near infra red reflectance (NIR) monitoring in precision agriculture (PAG).

The adoption of precision agriculture technologies is probably one of the greatest challenges and opportunities of the 21st century to expand the horizons of soil and plant analysis by matching the spatial variability of soil properties and crop demand with a variable input of agro-resources in the field. The high cost of soil sampling and chemical and physical analysis by conventional laboratories has restricted the full implementation of this technique at field level. Near Infra Red (NIR) analysis could be a cost-effective solution, but a whole paradigm shift in philosophy is needed to move away from the traditional approach in soil testing of taking a 'perceived' representative sample in which all the spatial variation is lost, to using a combination of grid soil sampling at a sample intensity of 4 to 10 cores per ha, in which the sub samples are analysed separately using rapid but less accurate methods such as NIR. Agricultural industries worldwide are showing increasing interest in the potential applications of near infrared (NIR) analysis in the fields of soil fertility, cane nutrition, cane quality testing and screening for resistance to certain pests and diseases. Recent investigations in the sugar and wheat industries have demonstrated the feasibility of using NIR scanning techniques for mapping spatial variability of important soil properties on a field scale. Soil properties that have been calibrated include gravimetric soil water, clay, buffer capacity, pH, electrical conductivity, titratable acidity, organic matter, mineralizable nitrogen, potential ammonia volatilization from urea, potential nitrification rate, and urease activity. Mapping spatial variability in this way will enable better utilization of resources such as the application of fertilizers.

"Nondestructive Direct Determination of Heroin in Seized Illicit Street Drugs by Diffuse Reflectance near-Infrared Spectroscopy"

Scientists in Spain are reporting an advance toward a new method for determining the purity of heroin that could save lives by allowing investigators to quickly identify impure and more toxic forms of the drug being sold on the street. Unlike conventional tests, it does not destroy the original drug sample, according to their report. It is scheduled for the Oct. 1 issue of ACS' Analytical Chemistry, a semi-monthly journal.

In the new study, Salvador Garrigues and colleagues point out that the purity of heroin can vary widely, since pushers often mix it with chalk, flour, or other "cutting agents." Because heroin users do not know the exact purity of the drug, they are more at risk for overdose and even death. Conventional tests for determining the purity of street heroin involve destructive and time-consuming sample preparation, the scientists say.

They studied 31 illicit drug samples from Spain that contained six to 34 percent heroin. The scientists tested the samples using the new analytical method, called Diffuse Reflectance Near-Infrared Spectroscopy (DR-NIR). It involves shooting a beam of infrared light into a sample to determine its chemical composition based on the wavelength of light emitted. The method quickly and accurately determined the chemical content of the samples without any prior sample preparation, the scientists say.

ATR Accessory enables polarized measurements in FT-IR.

Combining infrared spectroscopy with polarizer, Universal Attenuated Total Reflection (ATR) Polarization Accessory provides polarized measurements, which offer additional information on molecular structure of sample and help characterize materials. Accessory is particularly suited for crystal structure analysis, polymer and fiber orientation studies, and structural analysis studies of biomolecules. Variable angle polarizer can be removed for non-polarized measurements.

Urodynamix Submits 510(k) Filing to FDA for Second Generation Bladder Monitor

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 17, 2008) - Urodynamix Technologies Ltd. (TSX VENTURE:URO) today announced that it has submitted a 510(k) filing to the U.S. Food and Drug Administration (FDA) for its second-generation UroNIRS 2000 Bladder Monitor System - a non-invasive medical device that uses near infrared spectroscopy (NIRS) to diagnose lower urinary tract symptoms (LUTS) in a urology office setting.

UroNIRS 2000 is a standalone device that does not require conventional external or peripheral urodynamics equipment for its operation, unlike first generation UroNIRS technology. This will allow Urodynamix to broaden distribution of its UroNIRS products and expand from hospitals and clinics into urology office markets. This office-based device will provide Urodynamix and its current and future distribution partners with greater access to the 20 million men in the U.S. with symptoms of benign prostatic hyperplasia (BPH) who require diagnosis prior to effective treatment.

UroNIRS 2000 is based on a wireless tablet PC with Urodynamix's proprietary sensor configuration and is compact, portable and specifically designed for ease of use in the physician's office setting. The non-invasive procedure is used to confirm the presence of bladder outlet obstruction in men by identifying patients that have healthy bladder function yet suffer from weak urinary stream, hesitancy, urinary retention and related symptoms. UroNIRS 2000 is safer, faster, less expensive and more comfortable than conventional catheter-based diagnostics for the same condition. Clinical studies have shown that the UroNIRS device has an 86% success rate for accurately identifying obstructed male patients, most of whom are good surgical candidates.

Urodynamix will launch this new product with expanded distribution on a worldwide basis and expects to announce these new partnership(s) within 30 days.

"We are very pleased with the performance, quality, and customer-driven features of our UroNIRS system and are excited to be bringing this new technology to market as part of our strategy of developing the hospital market and then expanding into the Urologist office market," said Barry Allen, President and CEO of Urodynamix. "We look forward to FDA's review and the opportunity to provide our partners and physicians with an important new non-invasive approach to managing a widespread, chronic condition such as LUTS."

The typical review period for a 510(k) submission is approximately 90 days, and Urodynamix expects the first commercial orders of UroNIRS to ship in the first quarter of 2009 upon regulatory clearance.
