Arid Dune Ecosystems: The Nizzana Sands in the Negev Desert

Sand dune dynamics plays a key role in many arid deserts. This volume provides a synthesis of a specific sand dune ecosystem, the Nizzana site in the Negev Desert. Describing its climate and geophysical/geochemical properties of soils, geological history, flora and fauna, and past/present land-use patterns, it elucidates ecological and geomorphological processes and their interrelations, based on long-term monitoring, in situ experiments and satellite imagery. Particular attention is drawn to the impact of the topsoil biological crust in controlling water availability at local/regional scales. The interdisciplinary approach adopted in this case study offers a good example of a highly complex and dynamic system, which could easily be applied to other sandy ecosystems.

Apitherapy and therapeutic properties

Apitherapy is an alternate therapy that relies on the usage of honeybee products, most importantly bee venom for the treatment of many human diseases. Bee venom contains several active molecules such as peptides and enzymes that have advantageous potential in treating inflammation and central nervous system diseases, such as Parkinson’s disease, and Alzheimer’s disease and autoimmume diseases like reumatic and atherosclerosis .Bee venom (BV) is usually associated with pain since, when humans are stung by bees,local inflammation and even an allergic reaction can be produced. It also consists of a mixture of proteins and peptides, including enzymes such as Melittin and phospholipase A2 (PLA2) are the most abundant and studied compounds of BV Stings of hymenoptera can induce IgE-mediated hypersensitivity reactions in venom-allergic patients, ranging from local up to severe systemic reactions and even fatal anaphylaxis. skin is larger than any other organ in humans.

Anticoagulants and coronary artery disease

Blood thinners are medicines that help blood flow smoothly through your veins and arteries. There are two. The first is called anticoagulants (Warfarin, Heparin, Enoxaparin) and The second class of blood thinners is called antiplatelet (Aspirin, Ticagrelor , Clopidogrel). . Coronary arteries supply blood to the heart muscle. Coronary artery disorder or disease can have serious implications by reducing the flow of oxygen and nutrients to the heart muscle. This can lead to a heart attack and possibly death. Atherosclerosis. Medications to reduce the risk of blood clots, such as anticoagulants (including aspirin) and antiplatelet. , in particular aspirin, are effective in preventing platelet activation and thus thrombus formation and Clopidogrel is an inhibitor of platelet activation.

Analytic Number Theory : Lectures given at the C.I.M.E. Summer School held in Cetraro, Italy, July 11-18, 2002

The four contributions collected in this volume deal with several advanced results in analytic number theory. Friedlander’s paper contains some recent achievements of sieve theory leading to asymptotic formulae for the number of primes represented by suitable polynomials. Heath-Brown's lecture notes mainly deal with counting integer solutions to Diophantine equations, using among other tools several results from algebraic geometry and from the geometry of numbers. Iwaniec’s paper gives a broad picture of the theory of Siegel’s zeros and of exceptional characters of L-functions, and gives a new proof of Linnik’s theorem on the least prime in an arithmetic progression. Kaczorowski’s article presents an up-to-date survey of the axiomatic theory of L-functions introduced by Selberg, with a detailed exposition of several recent results.

Analysis and Algorithms for Service Parts Supply Chains

Services requiring parts has become a $1.5 trillion business annually worldwide, creating a tremendous incentive to manage the logistics of these parts efficiently by making planning and operational decisions in a rational and rigorous manner. This book provides a broad overview of modeling approaches and solution methodologies for addressing service parts inventory problems found in high-powered technology and aerospace applications. The focus in this work is on the management of high cost, low demand rate service parts found in multi-echelon settings. This unique book, with its breadth of topics and mathematical treatment, begins by first demonstrating the optimality of an order-up-to policy [or (s-1,s)] in certain environments. This policy is used in the real world and studied throughout the text. The fundamental mathematical building blocks for modeling and solving applications of stochastic process and optimization techniques to service parts management problems are summarized extensively. A wide range of exact and approximate mathematical models of multi-echelon systems is developed and used in practice to estimate future inventory investment and part repair requirements.

Algorithms and architectures for parallel processing ; 7th International Conference, ICA3PP 2007, Hangzhou, China, June 11-14, 2007, Proceedings

The improvements in computation and communication capabilities have enabled the creation of demanding applications in critical domains such as the environment, health, aerospace, and other areas of science and technology. Similarly, new classes of applications are enabled by the availability of heterogeneous large-scale distributed systems which are becoming available nowadays (based on technologies such as grid and peer-to-peer systems).Parallel computing systems exploit a large diversity of computer architectures, from supercomputers, shared-memory or distributed-memory multi processors, to local networks and clusters of p- sonal computers. With the recent emergence of multi core architectures, parallel computing is now set to achieve “mainstream” status. Approaches that have been advocated by parallel computing researchers in the past are now being utilized in a number of software libraries and hardware systems that are available for everyday use. Parallel computing ideas have also come to dominate areas such as multi user gaming (especially in the development of gaming engines based on “cell” arc- tectures).

Advances in multiple Sclerosis and Experimental Demyelinating Diseases

Challenging Charcot’s hypothesis that inflammatory response is the primary contributor to demyelination, Dr. Rodriguez and colleagues take a fresh, bold look at the causes and possible treatments of MS.Assuming oligodendrocyte injury as a prerequisite to MS, the authors explore viruses, toxins and genetic defects as possible culprits. They present novel methods to interrupt and reverse demyelination. This book examines the correlation between axonal loss and clinical deficits, including the implied role of the CD8+ T cell and perforin. It assesses proteases, specifically, kallikrein 6, which are strongly associated with active demyelination. By directing natural autoantibodies against oligodendrocytes that demonstrate remyelination in animal models, the authors envision clinical trials for remyelination enhancement.

Advances in Integrated Soil Fertility Research in sub-Saharan Africa : Challenges and Opportunities

Food insecurity is a central concern and a fundamental challenge for human welfare and economic growth in Africa. Low agricultural production, results in low incomes, poor nutrition, vulnerability to risks and lack of empowerment. Land degradation and soil fertility depletion are considered the major threats to food security and natural resource conservation in sub-Saharan Africa (SSA). Investments in technology, policy and institutional reforms are needed to increase agricultural productivity to ensure food security and sustained national economies. Past research has generated numerous soil fertility management technologies which if adopted could propel the African continent out of the poverty trap. However, these technologies have had little, if any, impact due to low adoption by the smallholder farmers.
