Taschenbuch. Condizione: Neu. Neuware -Through a comparison between Shakespeare¿s play and Li Yüs story, the author examines the striking historical, cultural and social background similarities the two literary works shared and then refers to the traditional Chinese Confucian ethics and classics, which convincingly reaveal that the 17th century English monarch almost shares the same moral standard with China in the Qing Dynasty (1636-1911). Actually, Shakespeare himself was an old-fashioned literary man who stuck to the traditional values and morals inherited from the Middle Ages; what Shakespeare praised and exhorted was just similar to what Confucius himself preached. People from east or west most often tend to share the mind alike. From the perspective of comparative culture study, the author also finds the closeness and similarity between Confucianism and the ancient Greek ethics. Based on these comparisons, the author ambitiously endeavors to validate the ¿affinity¿ of these two different cultures, in the hope of establishing a universally common culture that would benefit the whole world.Books on Demand GmbH, Überseering 33, 22297 Hamburg 120 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Intensive agriculture, poor soil management practices by farmers and other soil users, and overgrazing aggravates soil degradation; such that commonly resulting visible indices of degradation is soil erosion (by wind and water) and reduced crop yields. The negative impact of soil degradation due to inappropriate land management is very apparent in Africa and Nigeria in particular; with severe economic, social and environmental effect on the populace. In order to mitigate effects of soil degradation by restoring soils quality and fertility to enhance farmer livelihoods and food security, Conservation Agriculture strategies are advocated for Nigerian agriculture. Conservation Agriculture is a concept for natural resource-saving, strives to achieve acceptable profits with high and sustained production levels while concurrently conserving the environment. In the humid zones of Nigeria, intensive cultivation of available land using modern farming equipment increased soil disturbance and removal of soil cover to accelerate soil erosion. In particular, slopping lands that would not normally be put into regular cultivation are being intensively cultivated for crops like yam, cassava, maizeBooks on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The history of malaria in Argentina encompasses an extended period of over a hundred years of evolution since the late 19th century to the present. This long period has been arbitrarily divided into four phases, each characterized by particular features. The First phase encompassed the period between 1891 and 1939, and was characterized by prevailing environmental engineering works for malaria control. The Second phase is marked by the appearance of a new insecticide, Dichloro Diphenyl Trichloroethane or DDT, which has a determining impact on the endemic disease, causing the most significant reduction known in the endemic area until then, that marked the epidemiological malaria scenario in Argentina forever. At the Third phase, 1950 - 2008, previous achievements were gradually consolidated: the malaria transmission area was reduced and a method for epidemiological surveillance was established, which still survives to date, with little modifications. The Fourth phase, 2009 - 2015, the interruption of indigenous cases in the country is achieved and prepare a plan to prevent the reintroduction of cases.Books on Demand GmbH, Überseering 33, 22297 Hamburg 80 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Through the experience of countries that have drastically reduced their maternal mortality rates, we have learned much about the necessary policies and interventions. Access to clean water, sanitation and hygiene at home and in the clinic play a key role in reducing maternal mortality. Each year 290,000 women die from complications during pregnancy, birth and the neonatal period; and an estimated 10 to 20 million women suffer from related health complications. Almost 90% of the maternal deaths occur in Sub-Saharan Africa and South Asia. Much of this is preventable through practices of hygiene that have long been established. There has been a reduction by one-third over the past 20 years. In part related to increase in safe deliveries by skilled personnel, reduced fertility and antenatal care. Unfortunately the burden of mortality and morbidity still falls disproportionately on the poor and remains a great challenge in low resourced countries. This book is intended for policy makers and primary healthcare practitioners working in low resource environments as a guide for promoting hygiene in maternal child health services.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Poverty is a global problem which has been taking place across continents with different levels, and has become a major challenge for the development of each region, nation, ethnicity as well as locality. Vietnam ¿ an agricultural-aimed country ¿ with 70% of the population living in rural areas, whose intellectual standards and farming cultivation techniques are still limited, led to the low labor productivity, and low income. Poverty, as a consequence, has still taken place in numerous areas. The problem of poverty, hence, has been the Vietnamese Government¿s best concerns. To make the poor to break out from poverty is the foremost socio ¿ political objective and mission of the Government. Though it cannot be denied the success of such achievements, poverty reduction programs still remain limited. The Government has, however, still been facing with a number of difficulties and challenges needed to be overcome in order to implement the Millennium Goal of the United Nations, which Vietnam has already committed. These problems raise questions to the Government about how to apply the lessons learnt from the past as well as other nations more effectively in the next period Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The phenomenon of food chain globalization has become more and more obvious, through the emergence of new challenges and risks to human health and consumers¿ interests. This aspect was observed especially through the avalanche of fast-food products and carbonated soft drinks. The solution of these problems is the return to nature and tradition, by promoting the food treasure left us by our ancestors. Braga, a natural fermented beverage, of oriental origin, obtained from a cereal mixture, was considered in the past a pharma-food due to its nutritional virtues. Its reintroduction in the food chain is a healthy alternative to what the present day market offers. The first part of the book addresses the importance and role of fermentative industry and shows the components of braga describing its origins, the variety of recipes and its nutritional virtues. The second part of the work focuses on appropriate investigations relating to the identification and dosage of specific flavors drink, as well as it analyzes and identifies trace elements and heavy metals in braga. The book is useful for students, academicians and for persons interested in proper nutrition.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This work is devoted to the complex structural and magnetic investigations of the soft magnetic amorphous bilayered Co69Fe2Cr7Si8B14/Co59Fe12Cr7Si8B14 (Co/Co) ribbons. Their surface, bulk, and interface properties are compared with the properties of corresponding single-layered ribbons and the CoSiB/FeSiB (Co/Fe) bilayered ribbons analyzed in the previous work. All samples were prepared by rapid solidification of a melt using planar flow casting method. It is shown that the bulk microstructural and magnetic properties of the bilayered ribbons in both initial and thermally treated states are more outstanding influenced by the chemical composition of the side which is during ribbon processing in contact with air atmosphere. Analysis of thin interface (thickness lower than 1~µm) newly comprehends a method for observation of magnetic domains using the magneto-optical Kerr microscopy. Relaxation of the sample properties is checked by annealing at temperature 423 K for different times. Long-time annealing contributes to an improvement of the soft magnetic properties but simultaneously initializes the nucleation of crystallites on the surface of the Co/Co ribbons.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Due to an increase in greenhouse gas emissions more attention is being given to renewable energy. As wind is a renewable energy it is a clean and abundant resource that can produce electricity with virtually no pollutant gas emission. Induction generators are widely used for wind powered electric generation, especially in remote and isolated areas, because they do not need an external power supply to produce the excitation magnetic field. This book presents a self-Excited Induction Generator (SEIG) driven by wind turbine and supplying an induction motor which is coupled to a centrifugal pump. In first time, the effects of variation of excitation capacitance on system and rotor speed under different loading conditions have been analyzed and considered to optimize induction motor pump performances. In second time, a simple algorithm based on the direct torque and flux control (DTFC) with a Fuzzy logic controller scheme has been presented to maintain the terminal voltage of the generator and the DC bus voltage constant for variable rotor speed and load. The proposed controls scheme has shown very good voltage regulation even with sudden application and removal of load on the DC side.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Cancer is currently the most common human condition and has exceeded cardiovascular disease in terms of specific incidence and mortality in the last two years. Ovarian cancer has been known for a very long time as unpredictable in terms of the natural evolution. There are virtually unknown 'standard' progression and metastasis models as well as a differential and often inconsistent response to the adjuvant anti-cancer therapy. These uncertainties may be explained by insufficient knowledge of the expression of cell growth factor, of the tumor microenvironment and perhaps not least, of angiogenesis and lymphangiogenesis, which have been much less studied in the normal ovary and ovarian tumors than for other tumor locations. In the present study we aimed to study tumor angiogenesis and lymphangiogenesis aspects, in the hope that we will succeed to specify their prognostic value and characterize a number of new potential therapeutic targets. This work could not have been accomplished without the collaboration between the Histology and Gynecology Departments of 'Victor Babe¿' University Timi¿oara, and in this way I bring thanks to the colleagues from both departments.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Addressing the risk posed by the occurrence of strong and destructive earthquakes is a big challenge faced by authorities. Unlike hydro-meteorological events where prediction can be achieved with great precision and accuracy via state-of-the-art technologies and devices, there has been no means yet by which this can be done with earthquakes. To date, sound preparation for the uncertainty entails a lot of resources. This book introduces the Rapid Earthquake Damage Assessment System (REDAS), a GIS software as a tool to quickly assess and evaluate the damages from a devastating earthquake in near-real time fashion which can provide authorities with reliable data as bases for appropriate actions. It can offer an effective and efficient coping mechanism during and after an earthquake event due to its quick forecasting capabilities. Interested individuals may adopt the methodologies used so that through collective collaboration can work towards a more improved and reliable system. It also acts as an alerting tool on the occurrence of earthquakes and tsunamis as it can create a direct link to concerned agencies in the region via a dependable internet connection.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Children displaying behavioral problems can often continue with these nonconformities as they grow to maturity, creating a cycle of negativity that affects not only their own lives, but those of their family and the community. Evidence-based research have demonstrated that regular parent training program attendance can initiate a significant reduction in children¿s conduct problems, as parents acquire better child-management skills. Unfortunately, fewer than 15% of families participate in parent training; efforts to deliver the intended benefits of parenting interventions are often severely effected by high dropout rates and inconsistent attendance. Attrition is common and can occur during either assessment or program implementation. Thus, parent training programs (PTPs) real value is severely diminished. This study was designed to help parent training program directors and facilitators (using measurements) identify potential dropouts of PTPs, and devise initiatives wherein they stay in training. The Manual is an integral component because it generates information about parents whose perception of barriers to training interferes with their further program participation.Books on Demand GmbH, Überseering 33, 22297 Hamburg 52 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Levinas¿ philosophy of communication is responsibility for the Other in a specific walk from traditional conceptuality to articulation of unspeakable. Paradox of unspeakable speech and position that indicates overcoming phenomenology can be characterized as meta-methodological discourse as an utopian path to new humanism. Philosophical tradition failed to stop the evil and hate to the Other. Philosophy always comes too late, as Hegel said, like Minerväs awl that flies in the eve. However, as a conscience of mankind, philosophy is most valuable warning on the future consequence of acts made in contemporary world, as the only light that still shines form Plato¿s ideal world. Levinas gives this chance to philosophy as an utopian clue for possible changes of the world in a extreme conflict between Sollen and Sein. The question is; maybe utopia is a destiny for philosophical thought Levinas gives a suggestion about how human relation could be, as a last hope for humanity. Conscience of European, at the end of the millennia that glorified human mind, is not clear. How can we still think about humanism after wars, oppression, genocide, Holocaust, totalitarian regimes and terrorism Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The current book aims at casting new light on rendering the metonymic words of the SL/Arabic text which are very difficult to render as TL lacks equivalence , and as a resort, the translator paraphrases them, which certainly affect divinity of the Quranic Message. Since both Arabic and English belong to two different language, indeed, it is more likely to problematic and difficult task to render metonymic words more accurately and properly, hence, this book also aims at probing how metonymic words can be render from Qura'nic Arabic into English.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -During my last two years in college (2013-2015) I was intrigued by the volume of post-apocalyptic fictions that were bombarding American media. From vampire love stories to zombie apocalypses, it seemed that one way we began to deal with environmental devastation was through fantasizing about disaster in a way that made it more palatable or, in some cases, entertaining. My coursework at Bates College drew my interest to the role of children and their stereotypical innocence in fictional works. This piece examines the intersection of youthful imagination with fictitious environmental tragedy by exploring the question, ¿How can we become our own Romantic Children ¿ It urges the reader to engage in creative introspection and active thinking about her own role in our current environmental crisis.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -XAFS method is currently developed in both theoretical and experiment. It requires models to construct theory as well as to explain the experimental results or deduce the physical parameters from experimental data. The current XAFS theory now is harmonic theory and has been used to calculate some thermodynamic parameters. The result coincides well with XAFS spectrum measuring at low temperatures. But as temperature increases, phonons interact with each other and lead to anharmonic effects, resulting in various high-temperature universal XAFS for information on various structures. This study is aimed to provide theoretical basis of X-ray and XAFS spectrum and also participating in solving several important problems of modern XAFS theory when anharmonic effects or phonon interaction contribution are significant.Books on Demand GmbH, Überseering 33, 22297 Hamburg 124 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Enzymes are Proteins which catalyze variety of reaction in the Biological systems. There are many methods used to produce the enzymes among that the biological methods are widely used. In this type of biological method of production, solid state fermentation is applied for the production. In all the types of fermentation processes, the cultures has been prepared using yeast extract and peptone etc. These are added to the culture in terms of nutrients as a carbon and nitrogen sources for the microorganism. The cost of these chemicals are much expensive. So the alternative method has been proposed for the preparation of culture medium using some low cost agricultural byproducts such as defatted cotton seed, defatted soybean, mustard seed etc. The fermentation has to carryout using these type of low cost medium to check the productivity and enzyme activity.Books on Demand GmbH, Überseering 33, 22297 Hamburg 84 pp. Englisch.

This book is one of NOWPAP activities on marine biodiversity, which assessed the status of biodiversity and environment protection in typical coastal zones of northern China and investigated the impacts of socio-economic development to the local biodiversity in a relatively long period using the PSR framework based on the data of social economic development during 2004-2013 and related ecological environment studies.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The subject of my work is ¿The Living Death: Representation of Life Affected by Death in the Poetry of Emily Dickinson.¿ I argued that her speaker¿s life is immersed in sorrow while she anticipates and desires death. In the first chapter I described her accuracy in depicting the beauty of the surrounding world. However, beauty as well as the feeling of happiness are short-living states, as the speaker admits herself by finishing each of them with a pessimistic view of life. In the second chapter I concentrated on Dickinson¿s fears and obsessions which cause her existential pain. In this chapter I also wanted to show her criticism towards God who is not interested in his followers, thereby cares only about himself. In the third chapter I concentrated on death and how the speaker presents it. Moreover, I depicted grave as a reoccurring symbol in her poetry. As I concluded, death in Dickinson¿s poetry is omnipresent and, more importantly, omnipotent.Books on Demand GmbH, Überseering 33, 22297 Hamburg 52 pp. Englisch.

Neuware -Anisotropic shapes of gold nanoparticles are prepared using a modified seed method in the presence of silver ions or clusters in order to study the photo-thermal stabilities and the dynamics of the hot carriers induced by femtosecond laser pulses.It has been observed from studying their photostability to low-power UV irradiation (254 nm) at room temperature that, whereas spheres are very stable to photoirradiation, rods and prisms suffer from photocorrosion and finally dissolve completely with the production of Au(III) ions. Although gold nanospheres are also stable towards thermal treatment, the decomposition of the gold nanorods into spherical nanoparticle aggregates is mechanistically different from the case of nanoprisms.In regards to the hot carrier dynamics, it is found that the phonon-phonon (ph-ph) coupling is much slower in dots than in rods and prisms while electron-phonon (e-ph) coupling is almost the same in these particles.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.
