Download or read book Comet s Tale written by Steven Wolf and published by Algonquin Books. This book was released on 2012-10-09 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comet’s Tale is a story about a friendship between two former winners, both a little down on their luck, who together stage a remarkable comeback. A former hard-driving attorney, Steven Wolf has reluctantly left his job and family and moved to Arizona for its warm winter climate. There he is drawn to a local group that rescues abused racing greyhounds. Although he can barely take care of himself because of a spinal condition, Wolf adopts Comet, an elegant cinnamon-striped racer. Or does Comet adopt Wolf? In Comet’s Tale we follow their funny and moving journey as Wolf teaches Comet to be a service dog. With her boundless enthusiasm and regal manners, Comet attracts new friends to Wolf’s isolated world. And finally, she plays a crucial role in restoring his health, saving his marriage, and broadening his definition of success.

Download or read book Optical Materials written by Kelly S. Potter and published by Elsevier. This book was released on 2021-04-22 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical Materials, Second Edition, presents, in a unified form, the underlying physical and structural processes that determine the optical behavior of materials. It does this by combining elements from physics, optics, and materials science in a seamless manner, and introducing quantum mechanics when needed. The book groups the characteristics of optical materials into classes with similar behavior. In treating each type of material, the text pays particular attention to atomic composition and chemical makeup, electronic states and band structure, and physical microstructure so that the reader will gain insight into the kinds of materials engineering and processing conditions that are required to produce a material exhibiting a desired optical property. The physical principles are presented on many levels, including a physical explanation, followed by formal mathematical support and examples and methods of measurement. The reader may overlook the equations with no loss of comprehension, or may use the text to find appropriate equations for calculations of optical properties. Includes a fundamental description of optical materials at the beginner and advanced levels Provides a thorough coverage of the field and presents new concepts in an easy to understand manner that combines written explanations and equations Serves as a valuable toolbox of applications and equations for the working reader
Download or read book Icy Comets written by J. Clark Sawyer and published by Bearport Publishing. This book was released on 2015-01-01 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: What has one head, sometimes has tails, and orbits the Sun? A comet! These giant balls of ice, mixed with rock and dust, orbit the Sun. When they are very far from it, they have no tails. When they get closer to the Sun, they heat up and give off a cloud of gases and dust--and form tails. Early readers will be taken on a journey through outer space in simple yet captivating text as they learn these and other fascinating facts about comets. Each 24-page book features controlled text with age-appropriate vocabulary and simple sentence structure. Stunning photos closely align with descriptive text that will grab kids' attention. Emergent readers won't be able to stop turning the pages as they explore Earth's solar system. Get ready to blast off!

Download or read book 30 years of the Comet Assay an overview with some new insights written by Amaya Azqueta and published by Frontiers Media SA. This book was released on 2015-08-21 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: By means of this ‘Frontiers in Genetics’ research topic, we are celebrating 30 years of the Comet Assay. The first paper on this single-cell gel electrophoresis assay was published in 1984 by O. Ostling and K.J. Johanson (Biochem. Biophys. Res. Commun. Vol.123: 291-298). The comet assay is a versatile and sensitive method for measuring single - and double-strand breaks in DNA. By including lesion-specific enzymes in the assay, its range and sensitivity are greatly increased, but it is important to bear in mind that their specificity is not absolute. The comet assay (with and without inclusion of lesion-specific enzymes) is widely used as a biomarker assay in human population studies - primarily to measure DNA damage, but increasingly also to assess the capacity of cells for DNA repair. Ostling and Johanson (Biochem. Biophys. Res. Commun., 1984) were also the first to report experiments to measure DNA repair, by simply following the decrease of DNA damage over time after challenging cells with ionising radiation. However, this approach is time-consuming and laborious as it requires an extended period of cell culture and is therefore not ideal for biomonitoring studies, which typically require high-throughput processing of many samples. As an alternative approach, the in vitro comet-based repair assay was developed: a cell extract is incubated with a DNA substrate containing specific lesions, and DNA incisions accumulate. The in vitro comet-based repair assay has been modified and improved over the past decade: it was first devised to measure base excision repair of oxidised purines in lymphocytes (Collins et al., Mutagenesis, 2001), but has since been adapted for other lesions and thus other repair pathways, as well as being applied to tissue samples in addition to cell suspensions. Even after 30 years, the comet assay is still in a growth phase, with many new users each year. Many questions are repeatedly raised, which may seem to have self-evident answers, but clearly, it is necessary to reiterate them for the benefit of the new audience, and sometimes being forced to think again about old topics can shed new light. Different applications of the comet assay are discussed in this special issue, including: genotoxicity testing in different organisms, human biomonitoring, DNA repair studies, environmental biomonitoring and clinical studies. Furthermore, we consider and where possible answer questions, including the ones raised by Raymond Tice at the 8th International Comet Assay Workshop in Perugia (Italy 2009): What is the spectrum of DNA damage detected by the various versions of the comet assay?; What are the limitations associated with each application?; What should be done to standardize the assay for biomonitoring studies?; Can the comet assay be used to monitor changes in global methylation status?; What cell types are suitable for detecting genotoxic substances and their effects in vivo and in vitro?; Can the assay be fully automated?; and more. So this ‘Frontiers in Genetics’ research topic is written for the beginner as well as for the experienced users of the comet assay.
