Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Oxygen represents only 20% of the Earth's atmosphere, yet it is vital for the survival of aerobic organisms. There is a dark part of the use of oxygen that consists in generating reactive species that are potentially harmful to living organisms. Moreover, reactive oxygen species can combine with nitrogen derivatives and generate many other reactive species. Thus, living organisms are continuously assaulted by reactive species from external or internal sources. However, the real danger comes in the case of high concentrations and prolonged exposure to these species. This book presents an image of the mechanisms of action of reactive species and emphasizes their involvement in diseases. Inflammation and cancer are examined to determine when and how reactive species turn the evolution of a benign process to a malignant one. Some answers may come from recent studies indicating that reactive species are responsible for epigenetic changes. 216 pp. Englisch.…

Buch. Zustand: Neu.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is focused on different aspects of geophysical research, particularly on modern approach in subsurface imaging, tectonics, geohazard, seismicity, and Earth planetary system. Syntheses of results from regional and local studies combined with new techniques of geophysical data acquisition and interpretation from diverse geological provinces are presented. Some of the chapter explained clearly the geophysical technic that can image local sources in urban and rural settings in Israel. An example of studies on basement tectonics and fault reactivation in North America using integrated geophysical methods is also presented. Two modes of seismicity, one involving rotational seismology and another based on seismic response in Mexico using Hilbert-Huang transform (HHT) as an alternative technique for extracting data that will be useful for the assessment of potential earthquake, are discussed in other sets of chapters. The integration of geoelectric methods in another chapter demonstrated delimitation of the resistivity anomalies caused by different types of hydrocarbon contaminants and rocks in rural, industrial, and urban sites. The results of electrical resistivity method to define 1D and 2D electrical models from two datasets acquired in dry and rainy seasons in Panama (Central America) were used to show the relationship between electrical resistivity and volumetric water content. Petrophysical analyses show good fits between resistivity and volumetric water content and known parameters for rocks and soils. The study on Earth planetary system noted that at all stages of the Earth s formation, convective heat and mass transfer are the most important factors in the dynamics of the planet. The chapter on magnetics shows how remanent magnetization and self-demagnetization complicate the inversion and interpretation of magnetic anomaly with examples from iron deposit in South Australia. 160 pp. Englisch.…

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Human skin cancers, the most common type of tumors, represent a significant health burden. The deadliest is unquestionably melanoma. Half of melanomas have an activating mutation in the BRAF gene, prompting development of novel drugs, vemurafenib and dabrafenib, specifically targeting mutated BRAF. Trametinib and cobimetinib, which block MEK, a BRAF effector protein, have been used in combination with BRAF inhibitors. A promising new melanoma treatment is immunotherapy, approach that boosts patient's own immune system to attack cancer. Pembrolizumab and nivolumab inhibit PD-1, whereas Ipilimumab targets CTLA-4, another immunity check point, to boost the immune response. Here we focus on pathways, mechanisms, targets and treatments of human skin cancers, with particular emphasis on the new developments in the research on melanomas. 212 pp. Englisch.…

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In Slovenia, attorneys as a part of the justice system represent an autonomous and independent service that is regulated by law. As set out in the decision of the Constitutional Court of the Republic of Slovenia, there is no doubt that the legislature has to adopt the law to regulate the attorneys' profession, but in its attempt of such regulation, the legislature always collides with the constitutional requirement that the attorneys are autonomous and independent. Therefore, when regulating the attorneys' profession, the legislature has to address the issues of autonomy and independence and thus also the question of determining attorney tariffs, while certain issues must be left to be autonomously regulated within the attorneys' profession. The attorney tariff does not determine a mandatory price of legal services because an attorney and his client may always reach an agreement that is different from the attorney tariff. However, the tariff is binding when the court decides on the obligation to reimburse the party who has succeeded in a dispute for their attorney costs. With our research, we have empirically demonstrated that the existing attorney tariff in Slovenia unjustifiably drains smaller law firms, which guarantee an efficient coverage of population and smaller undertakings with a network of legal services. As a result, the economic autonomy and independence of law firms are compromised, and the right to effective judicial protection is unjustifiably restricted for the parties who succeed in a dispute. 126 pp. Englisch.…
