  • This book on investigative electrocardiography is addressed to investigators who are using electrocardiology as a research tool in epidemiological or clinical research or in investigations on possible adverse responses of new pharmacological agents. The primary emphasis of the book is on prognostic implications of ECG abnormalities in the conditions covered, including the prevalence and incidence of ECG abnormalities in contrasting populations. We excluded from our book cardiac disorders with a relatively low population prevalence that otherwise may be of great clinical interest.

  • Weeds severely affect crop quality and yield. Therefore, successful farming relies on their control by coordinated management approaches. Among these, chemical herbicides are of key importance. Their development and commercialization began in the 1940's and they allowed for a qualitative increase in crop yield and quality when it was most needed. This book blends review chapters with scientific studies, creating an overview of some the current trends in the field of herbicides.

  • Population geneticists study the genetic composition and variability of natural populations as well as the theories that explain this variability in terms of natural selection, mutation, recombination, genetic drift and gene flow. Population genetics was first developed among eukaryotes in an attempt to reconcile Darwin’s theory of evolution by natural selection and Mendelian genetics. When Darwin postulated that natural selection is the main force of evolutionary change, a great controversy was created.

  • Apolipoprotein E is a polymorphic glycoprotein in humans with a molecu-lar mass of 34.5 kDa. It is a component of chylomicron remnants, very low density lipoprotein, low density lipoprotein and high density lipopro-tein, and is primarily responsible for maintaining plasma lipid homeostasis. In addition to these well-documented functions, recent studies in experi-mental mouse models, as well as population studies, show that apolipo-protein E also plays an important role in the development of obesity and insulin resistance. ...

  • The OECD is a unique forum where the governments of 30 democracies work together to address the economic, social and environmental challenges of globalisation. The OECD is also at the forefront of efforts to understand and to help governments respond to new developments and concerns, such as corporate governance, the information economy and the challenges of an ageing population. The Organisation provides a setting where governments can compare policy experiences, seek answers to common problems, identify good practice and work to co-ordinate domestic and international policies....

  • The advance of chemicals in industry during the XX century gave rise to a number of highly aggressive compounds to human beings, and that altered the ecosystems balancing. Human population is inevitably exposed to environmental pollution through air-degraded products, water, the soil and food and their introduction into the food chain (Gomez et al, 2011). The use of pesticides has been recognized and accepted as an essential ingredient in the modern agriculture for the control of pests, which damage crops and as a result, they produce a severe loss in food production.

  • About 70% of the world’s population dwells in coastal zones. With the economic and population growth, the shortage in freshwater supply becomes increasingly acute. With surface water more and more depleted and polluted, coastal communities have turned to groundwater to make up for the shortfall. For domestic supply purposes, the percentage of groundwater use has increased to more than 40% on a worldwide basis.

  • Cellular automata make up a class of completely discrete dynamical systems, which have became a core subject in the sciences of complexity due to their conceptual simplicity, easiness of implementation for computer simulation, and their ability to exhibit a wide variety of amazingly complex behavior. The feature of simplicity behind complexity of cellular automata has attracted the researchers' attention from a wide range of divergent fields of study of science, which extend from the exact disciplines of mathematical physics up to the social ones, and beyond....
