Book excerpt: La « RMN-Chromatographique », associant la résonance magnétique nucléaire haute résolution avec rotation à l’angle magique (RMN HRMAS) à des mesures d’autodiffusion par des techniques utilisant des techniques d’écho de spin avec gradients de champ pulsés (PGSE), permet d’augmenter significativement la séparation spectrale des signaux de petites molécules en mélange à l’aide du pouvoir séparateur d’un support chromatographique. Cette technique analytique s’est également avérée utile à la détermination des interactions phase liquide / support chromatographique. L’objectif poursuivi dans ces travaux de thèse est de mieux comprendre les mécanismes mis en jeu lors du processus de séparation ainsi que d’expliquer les différences précédemment observées entre RMN-Chromatographique et chromatographie liquide. Dans ce contexte, une première étape consiste aux développements méthodologiques de la technique avec la détermination des conditions expérimentales adéquates à la mesure de coefficients de diffusion apparents justes et précis, ainsi qu’en l’amélioration de la qualité spectrale grâce à l’utilisation de solvants deutériés. Puis, l’impact du rapport de phases liquid/solide, de la porosité du support chromatographique et du solvant a été déterminé pour des composés aromatiques en présence de silices poreuses vierges et greffées ODS. Cette approche a permis de corréler les résultats obtenus en RMN-Chromatographique et en chromatographie liquide dans le cas d’un rapport de phases liquide/solide similaire pour les deux techniques. Enfin, dans le cadre du développement d’applications, le potentiel de la RMN-Chromatographique a été utilisé pour déterminer l’activité des silanols résiduels.

Available in PDF, EPUB and Kindle. Book excerpt: Genome Duplication provides a comprehensive and readable overview of the underlying principles that govern genome duplication in all forms of life, from the simplest cell to the most complex multicellular organism. Using examples from the three domains of life - bacteria, archaea, and eukarya - Genome Duplication shows how all living organisms store their genome as DNA and how they all use the same evolutionary-conserved mechanism to duplicate it: semi-conservative DNA replication by the replication fork. The text shows how the replication fork determines where organisms begin genome duplication, how they produce a complete copy of their genome each time a cell divides, and how they link genome duplication to cell division. Genome Duplication explains how mistakes in genome duplication are associated with genetic disorders and cancer, and how understanding genome duplication, its regulation, and how the mechanisms differ between different forms of life, is critical to the understanding and treatment of human disease.

Book excerpt: The era of chemical and biological megadeath is upon us, and the potential of deadly biowarfare attacks from governments, militant independent groups, and even individuals is far greater than it has been at any time in the past. At this time, more than twenty-five countries are developing, or have stockpiles of chemical and biological weapons, in many cases in sufficient quantities to wipe out the entire population of the world. So far the danger of chemical and biological aggression has been little acknowledged, and, at least in America, little prepared for by federal and local government. Most terrorist threats and attacks are not widely reported in the mainstream media. Although information about the proliferation of man-made diseases is carefully suppressed by governments and the media they will be covered in the pages of this book. Not only is America unprepared and ignorant of what is happening, but the people in government and scientific professions who do know, who should be warning the American public about the dangers of chemical and biological terrorism, are instead doing their utmost to hide this information from us; information that is vital for our survival.The information that is contained in the pages of this book will not be measured or calculated to reassure people that everything is fine, when reassurance is the exact opposite of what is needed at this time. It may even give you nightmares when you realise the real circumstance that we are in. The information in the pages that follow will be the truth about the biowarfare threat to America.

Available in PDF, EPUB and Kindle. Book excerpt: This report provides the most comprehensive and rigorous analysis of Iraqi income and expenditure in several decades. The report makes extensive use of the Iraq Household Socio-Economic Survey, the first nationwide income and expenditure survey since 1988. IHSES data is complemented income and expenditure data from a wide range of other measures of living standards, allowing us to analyze living standards in a holistic way. The analysis presented here was performed with two main goals first, to inform the Government s Poverty Reduction Strategy; and second, to serve as a baseline for future assessments of changes in living standards and the identification of critical issues for deeper examination. Iraqi living standards have two unusual characteristics. First, they have fallen over the past generation. Second, they feature surprisingly little inequality. These characteristics are both rooted in Iraq s recent history of authoritarian government, war, military occupation, insurgency, and civil strife leading to infrastructure destruction and population displacement. There have been few opportunities for individuals to prosper from professional or entrepreneurial activities. Decades of neglected investment have resulted in deterioration of social services and economic infrastructure. Consequently, individuals have lacked capabilities to prosper and an investment climate conducive to prosperity. School enrollment and life expectancy have declined. Extremely low returns to education reflect the combination of poor educational quality and lack of employment opportunities. In terms of economic infrastructure, access to reliable electricity and water, and even access to paved roads are low, are further reflections of decades of neglect. While the upper end of the distribution has been pulled down by a lack of opportunities, the lower end has been supported by direct government provision of food. The Public Distribution System (PDS) provides 85 percent of food needs. While PDS has been useful as a safety net for the poor and the vulnerable, the system is expensive, inefficient, and fiscally risky. Indeed, PDS food rations account for a far greater share of public spending than does education or health. Going forward, Iraq faces two main challenges. First, although Iraq does not have to develop from scratch, it faces a formidable challenge in re-development. Second, a shift by the Government is required from direct provision of basic subsistence toward investment in human capacities. The Government can provide an enabling environment through investments in economic infrastructure and services to business and citizens, thus allowing the population to make productive use of education and their own labor. Both challenges are now being taken up by the Poverty Reduction Strategy, which articulates a detailed set of required actions and outlines priorities for government spending.

Book excerpt: Wood adhesives are of tremendous industrial importance, as more than two-thirds of wood products in the world today are completely or partially bonded together using a variety of adhesives. Adhesive bonding offers many advantages over other joining methods for wood components, and there has been a great deal of R& D activity in devising new wood adhesives or improving the existing ones. The modern mantra in all industrial sectors is: "think green, go green," which has attracted much attention in the wood adhesive industry. Therefore, there is also a lot of research activity in synthesizing environmentally benign and human-friendly wood adhesives. This book is divided into four parts: Part 1: Fundamental Adhesion Aspects in Wood Bonding; Part 2: Synthetic Adhesives; Part 3: Environment-friendly adhesives; and Part 4: Wood Welding and General Paper. It addresses many different types of wood adhesives, as well as bonding (welding) of wood components without adhesives, a more recent development. The information contained in this book is valuable for individuals engaged in all aspects of wood adhesion and adhesives and, hopefully, will inspire new ideas in wood adhesives, a topic of vital industrial importance.
