Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The death rates after the start of the vaccination program are very different in the 47 countries representing Europe, although a very similar number of vaccine shots have been administered in the countries most affected by the pandemic. One exception to this is the UK, where the number of vaccinations is about three times higher. As in the rest of the world, a temporary decrease in the number of deaths in Europe was followed by an increase. However, the trends are different in each country, and a clear decrease is currently only taking place in ten European countries. Why do these differences exist Why is there an increase in the number of deaths The first cause is mistakes in the organization of the vaccine campaign in some countries. Often people had to wait in long queues outside vaccination centres in large cities, sometimes in cold weather. Everyone is waiting for herd immunity, but before that happens, if it ever happens, many more deaths will occur. Our real hope is a drift towards a non-lethal variant. In conclusion, COVID-19 has shown that the European Health System has to be completely reorganized in a proper manner. 80 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since 'purpose' in English grammar is mainly restricted to clauses of purpose, I decided to collect nearly all what relates to 'purpose'. Not all the materials I looked for exist in grammars under this title, but some others are found in what is called idioms or idiomatic expressions. That is, not only the books of grammar involve purpose meaning and usage, but also dictionaries of idioms or expressions imply this meaning. Although it is a hard job to come up with this area of research, there might be something done in this field in this booklet, i.e., the researchers need no effort to find any of the meaning of 'purpose'. Not only semantic meaning is explained here but also pragmatic one. It is intended to be an assistance for the learners practicing everyday language. In addition, it is hoped to be as a guide for teachers, researchers and students of English especially those who are interested in grammar. 52 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The simplicity and low energy consumption of membrane separation equipment has made it an attractive process for solving gas separation problems. The ability of a membrane to selectively pass a mixed component in a steady state and prevent other components from passing through is a characteristic of an ideal membrane. The process of gas penetration through the membrane is a relatively simple process and for various reasons such as reducing air pollution, environmental control or profit and loss in the industrial sector has received much attention. Therefore, they have developed very quickly since they were first used industrially in 1979. Due to the many applications of pure gases, membranes are now used in various processes in which these gases are present. Another application of membranes in gas separation is the separation of hydrogen from its mixture with nitrogen, methane or carbon monoxide. Separation of carbon dioxide and hydrogen sulfide from natural gas is another successful use of membranes. Today, membrane manufacturers are increasingly focusing on the use of this technology in production processes. 52 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The primary purpose for examining data is to be able to make good decisions. This requires the ability to build, not just a model, but a knowledge domain from the data. Data analysis is primarily concerned with how to extrapolate (out of sample ) data to provide business information. This book is about data modeling with examples from complex real-world data, expansion of the universe, Multiple Sclerosis, COVID-19, and the new Collated Distributions, Wilcoxon Regression and Levy Distribution. How does one construct the knowledge domain for a problem at hand from the data It requires building the context structure which consists of several individual cooperating models. Determining these models requires an understanding of how to partition the data which is not the same as stratification or machine learning. The partition data consists of individual processes which are evidenced as different probability distributions. Beware, much of statistical testing requires that specific axiomatic requirements be met which are usually not. This monograph teaches by way of complex data examples how to read this complex data and why the data is expecting us to ask much more questions than we do. 124 pp. Englisch.…

Few sulphated EPS modulate cell proliferation. The presence of sulphated groups in EPS may critically influence biological activity of the molecule. This has been investigated for EPS of few halophilic bacterias. Preliminary studies showed that hyperoversulphated forms of EPS cause a profound inhibition of cell proliferation in certain haematopoietic tumor cell lines. Further studies for exploring immunological importance of EPS sulphation showed that only oversulfated, but not native form of EPS, is a potent inducer of apoptosis for certain T-cell lines and T-cells of leukemia patients.

With solid lubricant particles dispersed in the matrix of aluminium alloy, this material exhibits good potential for resistance to wear and consequently, becomes more suitable for tribological applications. Aluminum based Metal Matrix composites (MMCs) have become a very valuable addition to the field of newer materials for high performance tribological applications.Aluminium based composites are being increasingly used in automobiles, aerospace, marine and mineral processing industries. Aluminium matrix composites are normally processed by the liquid casting technique or powder metallurgy route. Because of these advantages hybrid metal matrix composites (HMMCs) are using alternatives for industrial applications. Among the metal matrix composites, aluminium based composites are received attention of researchers due to its unique characteristics. 92 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The primary purpose of modeling is to be able to make good decisions. Having spent a decade in CMBS stress testing, in this monograph, I examine credit and default risk, that is, take it apart and deconstruct these concepts and show that defaults are easy to define but difficult to measure, but more importantly default risk cannot be used to determine credit risk. That pre-payers cannot be lumped together with defaulters as they belong to different population demographics. I then reconstruct the credit and default risk models to provide a much better model for forecasting securitized mortgage portfolio defaults. Vasicek is replaced by the Default Covered-Call Model which consists of the Sustainable Cash Flow Line, Lender 's Default Function and the Borrower 's Default Function. While the securitized mortgage industry addresses the Dodd-Frank risk-retention from a lender's perspective, from an investor's perspective, Dodd-Frank is wanting. Therefore, Dodd-Frank is vague and needs much rework. 96 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the main problems facing today's society is the issue of addiction. Today, addiction is one of the serious problems in physical, mental and social health. This process dealt a significant blow to the moral, economic, and social foundations of a society and led to corruption and degeneration from within. In other words, no society is completely immune from this problem. The most important psychological effects of addiction are: depression, anxiety, forgetfulness, psychosis and brain disorders, but the social problems caused by addiction can include crimes such as theft, prostitution and violence, increasing false jobs and reducing efficiency and a large number of families Called disturbed or broken. These problems need serious attention due to the number of addicts. The number of addicts was one million three hundred and twenty-five thousand. Some reports presented in our country the number of drug users is close to 1.8 to 3.3 million. Have announced. 96 pp. Englisch.…
