Silver Nanoparticles for Antibacterial Devices: Biocompatibility and Toxicity
by Huiliang CaoSince the potential toxicity of silver nanoparticles (Ag NPs) has raised serious concerns in the biomaterials and biomedical engineering community, Silver Nanoparticles for Antibacterial Devices: Biocompatibility and Toxicity brings together the synthesis, the physicochemical properties and the biological actions of Ag NPs, as well as the clinical demands for fabricating antibacterial medical devices, discussing how to suppress the side effects of nanomaterials and how to impart to them the selective toxicity. This book presents the two primary paradigms that have emerged in probing the antibacterial applications of Ag NPs, i.e. the active attacking releasing way and the conservative defending approach by taking advantage of various short-range actions; it shows readers how the ways in which Ag NPs have behaved can be engineered purposively. With contributions from leading international experts and extensive references listed in each chapter, this volume provides the general principles on controlling the physicochemical behaviors of nanomaterials and managing their toxicity risks.

Silver in Organic Chemistry
by Michael HarmataThe first authoritative book on using silver cations in organic chemistry—for catalysis and more! With more sophisticated catalytic methodologies fueling a resurgence in the study of cation-based chemistry, gold and platinum have stepped to the fore as the unique agents used to create new chemical reactions. Although these metals have become a primary focus of researchers in the field, another coinage metal that is often overlooked—but is as powerful as the others—is silver, a far less costly alternative to gold and platinum in aiding the development of new reactions. Making a strong case for the use of silver as a catalyst and structural element in organometal constructs, this authoritative book is the first to explore the benefits of using silver in organic chemistry by taking a close look at silver’s unique reactivity and structural characteristics for the development of new methods and materials. Silver in Organic Chemistry is: The first book to address catalysis using silver, whose use in organic chemistry is on the verge of exploding A resource for researchers wishing to do chemistry with silver cations, an area that stands in the shadow of gold chemistry, but still glistens, demonstrating that all that glitters is not gold—sometimes it’s silver! A guide for “first attempts” in working with silver cations Edited by a very well-respected, highly visible authority in this field Silver in Organic Chemistry promotes further scientific discussion by offering important new ways to examine the future possibilities of an emerging field. By elevating the importance of silver chemistry, this thought-provoking guide illustrates how this versatile metal can become an increasingly significant player in opening the door to new catalytic organic reactions and new organometal materials.

Silviculture of South Asian Priority Bamboos
by Ratan Lal BanikThis monographaims at bringing out a comprehensive collection of information on bamboovarieties in South Asia. The main focus of this book is to address theecological and economic significance of bamboos. Bamboo is a versatile group of plants, capable of providing ecological,economic and livelihood security to the people. In the tropics, especially therural areas in different countries of South Asia, most of the houses aremade of bamboos. In the hilly areas of Bangladesh, Bhutan, Nepal and India, thetribal people take bamboo shoots as one of their major food items sinceprehistoric days. With palatableshoots and grass like leaves bamboo plants have also been liked by many herbivore animals, such as, elephants,the wild cattle, Indian Bison, and some speciesof deer. The red-panda in the Himalayas, and primates,pigs, rats and mice, porcupines, and squirrels are also incidental feeders onsoutheast Asian bamboos. There has been a growing awareness in recent years about the values ofbamboo being an important means of economic growth and for improving thesocio-economic conditions of the rural poor. Bamboo as an industrialmaterial can substitute wood and that to at low cost. Due to increasing demandand squeezing of bamboo area the plants have been overexploited and the qualityand quantity of resource alarmingly getting depleted. Besides many new bamboobased industries have come up which also urgently require uninterrupted supplyof species wise bamboo resource. The south Asia region has bestowed with more than 300 bamboospecies with enormous diversities at species, ecological and geneticallevel. A number of bamboo species are found common among countriesof the region selected for various utilization potentials having wide range of ability to adjustenvironmental conditions of these countries and thus prioritized forcultivation. Both government and private planters in the region have started allocating funds, land andother logistics to raise large scale plantation of desired bamboospecies. This book has been drafted to find out answers of the most pertinentqueries based on the field observations on each of the bamboo species andknowledge learnt from the indigenous people living with bamboos in differentparts of south-east and south Asian countries. This monograph would beinteresting and useful to bamboo professionals, foresters, horticulturists,field level extension workers, nurserymen, planters, industrial entrepreneurs,ecologists, and valuable source of reference to the relevant researchers andstudents in the region.

Simon Cowell: From the Mailroom to Idol Fame (Extraordinary Success with a High School)
by Shaina C. IndovinoIn the last few decades, more and more people are going to college to further their education. It's hard to become a scientist, a professor, or a businessperson without getting some sort of college degree--but college isn't always necessary to achieve success. Some people are ready to enter the workforce right after high school. Simon Cowell was one of those people. The son of a British music executive, Cowell--instead of asking for help from his father--worked his way up through the music industry, starting from the mailroom. Though Simon found huge success in the music business, today the sarcastic star is most famous for his part in television shows like "American Idol", "America's Got Talent", and "The X Factor". Simon's known on screen as a short-tempered, sharp-tongued judge, but he's also had a role to play behind the scenes, creating and producing television shows in the United States and Britain. And what's most amazing about his story is that the music and television mogul has done it all without a college degree!
Simon Marius and His Research (Historical & Cultural Astronomy)
by Hans Gaab Pierre LeichThe margravial court astronomer Simon Marius, was involved in all of the new observations made with the recently invented telescope in the early part of the seventeenth century. He also discovered the Moons of Jupiter in January 1610, but lost the priority dispute with Galileo Galilei, because he missed to publish his findings in a timely manner.The history of astronomy neglected Marius for a long time, finding only the apologists for the Copernican system worthy of attention. In contrast the papers presented on the occasion of the Simon Marius Anniversary Conference 2014, and collected in this volume, demonstrate that it is just this struggle to find the correct astronomical system that makes him particularly interesting. His research into comets, sunspots, the Moons of Jupiter and the phases of Venus led him to abandon the Ptolemaic system and adopt the Tychonic one. He could not take the final step to heliocentricity but his rejection was based on empirical arguments of his time.This volume presents a translation of the main work of Marius and shows the current state of historical research on Marius.

Simple Mathematical Models of Gene Regulatory Dynamics
by Michael C. Mackey Moisés Santillán Marta Tyran-Kamińska Eduardo S. ZeronThis is a short and self-contained introduction to the field of mathematical modeling of gene-networks in bacteria. As an entry point to the field, we focus on the analysis of simple gene-network dynamics. The notes commence with an introduction to the deterministic modeling of gene-networks, with extensive reference to applicable results coming from dynamical systems theory. The second part of the notes treats extensively several approaches to the study of gene-network dynamics in the presence of noise--either arising from low numbers of molecules involved, or due to noise external to the regulatory process. The third and final part of the notes gives a detailed treatment of three well studied and concrete examples of gene-network dynamics by considering the lactose operon, the tryptophan operon, and the lysis-lysogeny switch. The notes contain an index for easy location of particular topics as well as an extensive bibliography of the current literature. The target audience of these notes are mainly graduates students and young researchers with a solid mathematical background (calculus, ordinary differential equations, and probability theory at a minimum), as well as with basic notions of biochemistry, cell biology, and molecular biology. They are meant to serve as a readable and brief entry point into a field that is currently highly active, and will allow the reader to grasp the current state of research and so prepare them for defining and tackling new research problems.

Simple Statistical Tests for Geography
by Danny McCarrollThis book is aimed directly at students of geography, particularly those who lack confidence in manipulating numbers. The aim is not to teach the mathematics behind statistical tests, but to focus on the logic, so that students can choose the most appropriate tests, apply them in the most convenient way and make sense of the results. Introductory chapters explain how to use statistical methods and then the tests are arranged according to the type of data that they require. Diagrams are used to guide students toward the most appropriate tests. The focus is on nonparametric methods that make very few assumptions and are appropriate for the kinds of data that many students will collect. Parametric methods, including Student’s t-tests, correlation and regression are also covered. Although aimed directly at geography students at senior undergraduate and graduate level, this book provides an accessible introduction to a wide range of statistical methods and will be of value to students and researchers in allied disciplines including Earth and environmental science, and the social sciences.
