Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Skin is a natural barrier to infection. Surgical breakage of skin can lead to surgical site infections (SSIs). SSIs are relatively common and constitute a problematic issue in surgical procedures. Most common organisms include Gram-positive, such as Staphylococcus and Streptococcus, as well as Gram-negative, such as Pseudomonas and others, bacteria. The extent and outcome of SSI can vary widely depending on the procedure, organism, extent, and other factors, and can result in discomfort, severe morbidity, or even life-threatening conditions.It is thus mandatory to be aware of and follow WHO and CDC guidelines for the prevention of SSIs and to reduce risk factors for acquisition. This book sheds light on certain aspects related to SSIs and how to avoid them. 98 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The term 'metallic glasses' is widely used to denote the amorphous alloys obtained by rapid quenching techniques. These materials are characterized by short range atom ordering without translational periodicity of the structure. Kinetic and thermodynamic metastability is one of the main characteristics generally related to metallic glasses, while their thermally induced microstructural transformations could result in deterioration or improvement of the functional properties. Due to their favorable magnetic, electrical, mechanical, and anti-corrosion properties, metallic glasses as new and attractive materials have found application in many areas of modern industries - electronics, construction industry, aerospace industry; as well as chemistry, biomedicine, and surgery. 98 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The volatility of the economy, political instability, and greater demands on not-for-profit organisations (non-profits) will require considerable rethinking and refocusing for many organisations. These days, non-profits evolve while attempting to regain financial ground, focusing more on workflow, fundraising, and staffing. The book highlights the upcoming challenges, among others funding instability, with a continuing shift in funding with more grantors focusing on funding mobilisation instead of intervention. Another challenge is clustering, which is where organisations are more likely to band together with others to share overhead costs, resources, and personnel. The non-profit sector will undergo essential integrations where the free flow of data and information will be crucial. Non-profits will continue to adjust their goals and priorities to meet changing trends. While the top priority was once acquiring new donors, that has now been eclipsed by the need for non-profits to engage the community and promote general brand awareness. 92 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Helminthiasis is a disease caused by parasitic helminths such as flukes, tapeworms, filarial worms, and nematodes. These parasites cause diseases that pose serious health problems, especially in developing countries of the world. Helminthiasis is a reflection of poor socio-economic conditions, which impacts on the social life of victims and economic development. Parasitic helminths live in a variety of habitats in their hosts and are far more widespread than we think. Gastrointestinal helminths are the largest group that affects their host directly through feacal-oral routes. This book not only provides insight into antihelminthic resistance in livestock but it also discusses soil transmitted helminths in pregnant women and children and filariasis as a debilitating disease. The book covers the prevention and control of helminthiasis of which adequate diagnosis is crucial. This book helps to close the information gap on helminthiasis, which has otherwise been classified as belonging to the group of neglected diseases and overlooked as a serious cause of morbidity and mortality of humans and domestic animals. The information in this book proposes that helminthiasis needs more global attention. 112 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Thermosoftening Plastics are polymers that can be manipulated into different shapes when they are hot, and the shape sets when it cools. If we were to reheat the polymer again, we could re-shape it once again. Modern thermosoftening plastics soften at temperatures anywhere between 65 ºC and 200 ºC. In this state, they can be moulded in a number of ways. They differ from thermoset plastics in that they can be returned to this plastic state by reheating. They are then fully recyclable because thermosoftening plastics do not have covalent bonds between neighbouring polymer molecules. Methods of shaping the softened plastic include: injection moulding, rotational moulding, extrusion, vacuum forming, and compression moulding. The scope of this book covers three areas of thermosoftening plastics, thermoplastic materials, and their characterization. The following tests are covered in the book: thermal analysis (differential scanning calorimetry, heat deflection temperature test), optical properties tests (fluorescence spectroscopy, UV spectroscopy), and mechanical properties tests (thermogravimetry, rheometry, short term tensile test). 124 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Cultivation of grain crops has been rightly recognized as one of the main drivers in shaping human civilizations. Considering their key role in fulfilling a major portion of the global food needs, grain crops are the most widely grown crops around the world. Unfortunately, like many other agronomic crops, grain crops are quite vulnerable to climate change and this has posed multifaceted threats to agricultural sustainability. To add to the menace, the deteriorating quantity and quality of both land and water as primary factors of production are further aggravating the scenario. Confronting such challenges demands innovative adaptation strategies through intensification of grain crop production that can ensure grain self-sufficiency worldwide. 156 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Geopolymers are applied to material classes that are chemically transformed from low crystallinity aluminusilicates to three-dimensional inorganic polymers (tectosilicates). The resulting material has properties similar to natural minerals, so it is called artificial rock. However, these materials exhibit a chemical composition and mineralogical structure similar to feldspar, feldspathoidal, and zeolites consisting of a polymeric Si¿O¿ Al framework, with a microcrystalline or an amorphous structure. Although geopolymers have attractive engineering and environmental characteristics, there are some challenges in commercializing these materials. In this book, these challenges will be addressed along with introducing the functional geopolymers as an effective approach to commercializing these materials and making them economically feasible. 180 pp. Englisch.
