Presents a comprehensive review of the multi-faceted actions of vitamin D relating both to skeletal and extra-skeletal action. Researchers from all areas of vitamin D will gain insight into how clinical observations and practices can feed back into the research cycle and will, therefore, be able to develop more targeted genomic and proteomic insights into the mechanisms of disease.
Fatigue Science for Human Health
Fatigue is quite a familiar sensation, one that everyone is likely to have experienced. Its molecular and neural mechanisms have not yet been elucidated, however, probably because of the complicated nature of its causes. To provide a broad forum for discussion, the International Conference on Fatigue Science was organized, the first being held in 2002 in Sandhamn, Sweden, and the second in 2005 in Karuizawa, Japan. Subsequently it was decided that the papers presented at the two conferences should be collected and incorporated in this pioneering work, Fatigue Science for Human Health. The book summarizes fatigue researchers' achievements, explains the status of the research on fatigue, and presents perspectives on remedies for chronic fatigue and chronic fatigue syndrome. The result is an authoritative guide to recent progress in the molecular and neural mechanisms of fatigue and in the development of the ways to prevent and overcome fatigue and chronic fatigue.
Fasting and Immunity
Ramadan is the ninth month of the Islamic lunar calendar and is observed by Muslims as a month of fasting. All Muslim adults are expected to fast; nevertheless, certain subgroups, including sick, frail subjects, and pregnant women, among others, are exempted. Ramadan fasting has been shown to impact on body systems in different manners. The influence of Ramadan fasting on immune system regulation remains elusive; however, immune system changes, such as the modulation of body response to various infectious, stressful, and other harmful events, are of great interest during fasting.
Fast Reactions in Energetic Materials : High-Temperature Decomposition of Rocket Propellants and Explosives
Modern energetic materials include explosives, blasting powders, pyrotechnic m- tures and rocket propellants [1, 2]. The study of high-temperature decomposition of condensed phases of propellants and their components (liquid, solid and hybrid) is currently of special importance for the development of space-system engineering [3, 4]. To better understand the burning mechanisms (stationary, nonstationary, - steady) of composite solid propellants and their components, information about the macrokinetics of their high-temperature decomposition is required [5]. To be able to evaluate the ignition parameters and conditions of safe handling of heat-affected explosives, one needs to know the kinetic constants of their high-temperature - composition. The development of new composite solid propellants characterized by high performance characteristics (high burning rates, high thermal stability, stability to intrachamber perturbations, and other aspects) is not possible without quanti- tive data on the high-temperature decomposition of composite solid propellants and their components [6].
Fas Signaling
Fas Signaling is focused on the signaling mechanisms and biology of the prototypic death receptor Fas, also called CD95 or APO-1. The chapters of this book cover, besides the well recognized apoptosis-related functions of Fas, its emerging role as a proinflammatory cytokine and as an inducer of alternative forms of cell death. Fas Signaling aims to provide the reader with an up-to-date survey of the various aspects of Fas biology and the open questions of the field are addressed. This title is intended for Ph.D and post-doctoral students starting to work in the field, but is also useful for everyone with an interest in the biology of this exciting molecule.
Facts about the most three common types of cancer in Syria
Cancer occurs when the cellular reproduction process goes out of control. In other words, cancer is a disease characterized by uncontrolled, uncoordinated and undesirable cell division. Unlike normal cells, cancer cells continue to grow and divide for their whole lives, replicating into more and more harmful cells. But death rates are falling, thanks to earlier detection of tumours and improved use of existing treatments - mainly chemotherapy biological therapy and radiotherapy. And today Our research tends to spot the light on the most common types of cancers in Syria which was found to be lung cancer, colorectal cancer, and breast cancer.

Extracting Methods of Essential laurel oil and Fixed oil, Their effects on bacteria
Laurus nobilis is an evergreen plant belonging to the Lauraceae family, native to Southern Europe and the Mediterranean area. This is the report on the composition and bioactivity of laurel essential oil (EO) from leaves and extraction essential oil by two solvents (water and ethanol 69%) using by two devices (Clevenger and evaporator) then we apply the effect of oil and extract on the bacteria. there are some differences between the extraction by water and ethanol . The antibacterial properties of laurel EOs were examined according to the agar well diffusion method The leaf EO showed antibacterial activities against almost all strains of the microorganisms tested, whereas the twig EO was only able to inhibit Staphylococcus aurous and Escherichia coli were the bacterial strains that showed the highest resistance to the laurel EO. The results can benefit the EO industry and bio pesticide development.

The book presents plans, metrics, frameworks, mechanisms and financial innovations that can be, and are being, implemented through the financial markets in order to save and protect species, enhance biodiversity and, at the same time, preserve the financial markets and the business world.
Extensionalism : The Revolution in Logic
This vivid and thought-provoking book by the Israeli logician Nimrod Bar-Am impels one to rethink the place of logic in Western thought. It shows that the history of logic from Aristotle to Tarski is the history of the gradual undoing of the classic conflation of logic and empirical science. It sets tomorrow’s agenda for philosophers and historians of logic and scientific method by taking as its starting point the mere fact that, curiously, ancient logic is not as formal as current literature presents it. Rather, as Bar-Am explains, modern formal logic became possible only after a series of bold criticisms of the magnificent Aristotelian system. These criticisms begin with David Hume’s declaration that logic does not sanction induction, follow on with Kant’s view of logic as an extremely limited system, and culminating with Booles’ introduction of logic as an extensional system, and Russell’s solution to his own paradox.
Exploring Resilience : A Scientific Journey from Practice to Theory
Resilience has become an important topic on the safety research agenda and in organizational practice. Most empirical work on resilience has been descriptive, identifying characteristics of work and organizing activity which allow organizations to cope with unexpected situations. Fewer studies have developed testable models and theories that can be used to support interventions aiming to increase resilience and improve safety. In addition, the absent integration of different system levels from individuals, teams, organizations, regulatory bodies, and policy level in theory and practice imply that mechanisms through which resilience is linked across complex systems are not yet well understood. Scientific efforts have been made to develop constructs and models that present relationships; however, these cannot be characterized as sufficient for theory building. There is a need for taking a broader look at resilience practices as a foundation for developing a theoretical framework that can help improve safety in complex systems.

Exogenous and endogenous factors affecting happiness, happy mind, happy life
Emotions are the language of the soul. Our brain is the emotional center where every emotion is produced including happiness. Happiness underlying factors are considerable from two dimensions: endogenous factors and exogenous factors Therefore, this research aimed to consider biological factors that underlie happiness. The research is divided into several sub-groups (brain, genetics, neurotransmitters, endocrinology, hormones, drugs, diseases, and other exogenous factors). In spite of difficulties in finding special genes, several genes distributed to emotion and mood. Neuroscience studies showed that some part of brain (e.g. amygdala, hipocamp and limbic system) and neurotransmitters (e.g. dopamine, serotonin, norepinefrine and endorphin) play a role in control of happiness. A few studies pointed to the role of cortisol and adrenaline (adrenal gland) and oxitocin (pituitary gland) in controlling happiness.
Evolvable systems : From biology to hardware ; 6th International Conference, ICES 2005, Sitges, Spain, September 12-14, 2005, Proceedings
The flying machines proposed by Leonardo da Vinci in the fifteenth century, the se- reproducing automata theory proposed by John von Neumann in the middle of the twentieth century and the current possibility of designing electronic and mechanical systems using evolutionary principles are all examples of the efforts made by humans to explore the mechanisms present in biological systems that permit them to tackle complex tasks. These initiatives have recently given rise to the emergent field of b- inspired systems and evolvable hardware. The inaugural workshop, Towards Evolvable Hardware, took place in Lausanne in October 1995, followed by the successive events of the International Conference on Evolvable Systems: From Biology to Hardware, held in Tsukuba (Japan) in October 1996, in Lausanne (Switzerland) in September 1998, in Edinburgh (UK) in April 2000, in Tokyo (Japan) in October 2001, and in Trondheim (Norway) in March 2003. Following the success of these past events the sixth international conference was aimed at presenting the latest developments in the field, bringing together researchers who use biologically inspired concepts to implement real systems in artificial intelligence, artificial life, robotics, VLSI design, and related domains. The sixth conference consolidated this biennial event as a reference meeting for the community involved in bio-inspired systems research. All the papers received were reviewed by at least three independent reviewers, thus guaranteeing a high-quality bundle for ICES 2005.
Evolutionary Intelligence : An introduction to theory and applications with Matlab
This book gives a good introduction to evolutionary computation for those who are first entering the field and are looking for insight into the underlying mechanisms behind them. Emphasizing the scientific and machine learning applications of genetic algorithms instead of applications to optimization and engineering, the book could serve well in an actual course on adaptive algorithms.
Evolutionary Computer Music
The evolutionary computation approach to music is an exciting new development for composers and musicologists alike. For composers, it provides an innovative and natural means for generating musical ideas from a specifiable set of primitive components and processes. For musicologists, these techniques are used to model the cultural transmission and change of a population's body of musical ideas over time. In both cases, musical evolution can be guided by a variety of constraints and tendencies built into the system, such as realistic psychological factors that influence the way music is expressed, experienced, learned, stored, modified, and passed on among individuals. This book discusses not only the applications of evolutionary computation to music, but also the tools needed to create and study such systems. These tools are drawn in part from research into the origins and evolution of biological organisms, ecologies, and cultural systems on the one hand, and from computer simulation methodologies on the other. They can be combined to create surrogate artificial worlds populated by interacting simulated organisms in which complex musical experiments can be performed that would otherwise be impossible.
Evolution from Cellular to Social Scales
Evolution is a critical challenge for many areas of science, technology and development of society. The book reviews general evolutionary facts such as origin of life and evolution of the genome and clues to evolution through simple systems. Emerging areas of science such as "systems biology" and "bio-complexity" are founded on the idea that phenomena need to be understood in the context of highly interactive processes operating at different levels and on different scales. This is where physics meets complexity in nature, and where we must begin to learn about complexity if we are to understand it. Similarly, there is an increasingly urgent need to understand and predict the evolutionary behavior of highly interacting man-made systems, in areas such as communications and transport, which permeate the modern world. The same applies to the evolution of human networks such as social, political and financial systems, where technology has tended to vastly increase both the complexity and speed of interaction, which is sometimes effectively instantaneous.
Evaluation of the use of medicine plants in cancer treatment
Turmeric (Curcuma longa) and ginger (Zingiber officinale) have been widely studied for their potential anticancer effects, primarily due to the bioactive compounds curcumin and gingerol. Both compounds exhibit significant therapeutic properties, including anti-inflammatory, antioxidant, pro-apoptotic, and anti-angiogenic activities, which target key pathways implicated in cancer progression, such as NF-κB, STAT-3, and mTOR. Through these mechanisms, curcumin and gingerol inhibit tumor growth, reduce metastasis, and enhance the efficacy of conventional cancer treatments.
Evaluating evidence of mechanisms in medicine : Principles and procedures
This book is the first to develop explicit methods for evaluating evidence of mechanisms in the field of medicine. It explains why it can be important to make this evidence explicit, and describes how to take such evidence into account in the evidence appraisal process. In addition, it develops procedures for seeking evidence of mechanisms, for evaluating evidence of mechanisms, and for combining this evaluation with evidence of association in order to yield an overall assessment of effectiveness.
Eutrophication of Shallow Lakes with Special Reference to Lake Taihu, China
Eutrophication and algal blooms are worldwide environmental issues in lakes. The eutrophication process and formation mechanisms of algal blooms are particularly complicated in shallow lakes due to the strong lake–land, air–water and water–sediment interactions. This volume features papers presented at the International Symposium on the Eutrophication Process and Control in Large Shallow Lakes – with Special Reference to Lake Taihu, a Shallow Subtropical Chinese Lake, held in Nanjing, China, 22–26 April, 2005. The topics include: physical processes and their effects on shallow lake ecosystems; biogeochemistry of sediments and nutrient cycling in shallow lakes; algal blooms and ecosystem response in shallow lakes; eutrophication control and restoration in shallow lakes; and resource exploitation, environmental protection and sustainable management in shallow lakes.
