Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fractionation, in the most general sense, could mean any process whereby a mixture is separated into different components or fractions. Examples of fractionation processes include dephlegmation, fractional distillation, fractional freezing, fractional melting, isotope fractionation, and other separation techniques. Of the many and varied separation processes available, fractionation plays a major part, and capital investment in fractionation equipment and processes may form a significant fraction of industrial processing investment. Fractionation as a separation technique is extensively used in widely diverse areas such as the application of geochemical fractionation of metals in sediments of water reservoirs, fractionation of polysaccharides from selected mushroom species, and fractional distillation of bio-oil produced by pyrolysis of certain palm seeds. 88 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A large amount of energy is consumed in the industry to meet the power needed for production processes. In order to meet the heat and mechanical power needs required for many industrial processes, natural gas, petroleum fuel, and electricity are mostly used as energy sources. In addition to the efficient use of energy in order to reduce operating costs in industrial applications, alternatives such as efficient use of energy for conservation of resources and climate, energy recovery, renewable energy preferences, and energy production from wastes are becoming more common. With proper energy management, it is possible to increase energy efficiency independently of the size of the industry and the technologies used in the process. The development of new alternatives for energy efficiency and saving is crucial to meet the growing world energy needs and to compete effectively with fossil fuels and thus reduce greenhouse gases. This small book is a collection of research and reviewed chapters dealing with energy-efficient materials and strategies in different conditions.The Editors would like to record their sincere thanks to the authors for their contributions. 86 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book deals with the rapid progress in the area of myelodysplastic syndromes (MDS). MDS are a group of age-associated heterogeneous malignant bone marrow stem cell disorders. MDS are characterized by ineffective hematopoiesis, which leads to refractory cytopenias and to clonal instability. Patients with MDS have myeloid dysplasia, intramedullary apoptosis and an increased risk of transformation to acute myeloid leukemia (AML). The use of next generation sequencing has allowed for the identification of molecular mutations in several genes in about 90% of MDS patients. Several mutations will likely be incorporated into future prognostic scoring systems for MDS. About 50% of MDS cases are characterized by the presence of cytogenetic abnormalities. The correct morphological and cytogenetic analysis interpretation plays an important role in diagnosis and prognosis of these disorders. Cell death and an inflammatory gene signature are associated with MDS. Better understanding of the genetic and molecular mechanisms of MDS pathogenesis provides an opportunity for new treatment strategies to be developed. Promising novel therapies targeting pathophysiological mechanisms of MDS are being studied but the drugs currently used in MDS therapy remain limited. The only curative therapy for MDS is allogeneic hematopoietic stem cell transplantation. Recent advances in strategies to minimize transplant-related toxicity make this treatment possible for more MDS patients who are sufficiently fit. 120 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Among the most prized and revered democratic institutions are elections. Few other actions typify what it means to participate in the democratic process in the same way that turning up, casting a ballot, and then having that ballot be part of determining who will control power has. Indeed, elections are at the center of what we view as democracy and much ink has been spilled in attempting to explain just how essential the electoral action is to democracy. In this volume our authors explore elections both from an understanding of the systems that govern elections across both the developed and developing world, and from the perspective of the individual voter who participates in that system. Taken together these analyses provide an intriguing look into this core aspect of democracy. 158 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Midwifery across the globe faces different issues. In some countries the autonomy of the profession is a tradition, while in some societies midwives struggle to practice autonomously the basic competencies. In one part of the world the medicalisation of childbirth is the main issue, preventing the natural processes of pregnancy and childbirth to flow at their own pace, while in other parts of the world midwives struggle with lack of resources to provide safe midwifery care. The authors of this book practice midwifery in different cultures and within different social contexts. They have to deal with different obstacles and seek solutions to diverse problems.
