Book Description
Le concept de dentisterie à minima, avec une préservation tissulaire et un bio mimétisme des restaurations, est le fil rouge de la pratique dentaire actuelle. La dentisterie connaît une évolution remarquable dans le domaine des restaurations des secteurs antérieurs. On constate un progrès des techniques adhésives notamment par l'amélioration des matériaux, l'amélioration des propriétés mécaniques, des propriétés de collage et une prise de conscience de l'importance de l'esthétique. Les composites antérieurs occupent une place centrale dans le gradient thérapeutique actuel. Leurs propriétés colorimétriques, mécaniques et leur qualité de surface leur permettent une indication de plus en plus large. Les nouvelles méthodes de stratification permettent un excellent rendu esthétique et fonctionnel. La qualité et la pérennité du résultat dépendront en grande partie de la technique de préparation de la dent. En effet, la réussite du projet esthétique, est significativement influencée par le bon respect du protocole de stratification mais aussi par la précision de la préparation de la limite dent-résine. Le but de ce travail est de réaliser un travail de revue bibliographique afin de comparer les différents types de préparations selon les différents critères qui s'imposent, qui sont : l'aptitude au collage, l'intégration esthétiques, les propriétés mécaniques et la préservation tissulaire.

Book Description
The contents of this book touch on the all major dental biomaterials: polymers, composites, ceramics and metals. The first part introduces the readers to the surface physicochemical and mechanical characterizations at the nanoscopic level, and the use of finite element analysis. The second part discusses dental adhesion, resin-based composites, polymerization contraction stress, impression materials and soft liners for total prosthesis. The third part deals with ceramics in restorative dentistry: zirconia and lithium disilicate, the fractography of dental ceramics, as well as bioglass for bone growth. The fourth part discusses the toxicity of mercury in dentistry, and the use of preventive materials for dental diseases. The concluding part identifies imminent techniques for dental biomaterials, such as additive manufacturing (3D printing), and bioprinting in dentistry.

Book Description
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 Description
From environmental management to land planning and geo-marketing, the number of application domains that may greatly benefit from using data enriched with spatio-temporal features is expanding very rapidly. This book shows that a conceptual design approach for spatio-temporal databases is both feasible and easy to apprehend. While providing a firm basis through extensive discussion of traditional data modeling concepts, the major focus of the book is on modeling spatial and temporal information.
