Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Ants play important roles in natural ecosystems. These eusocial insects are omnivorous feeders and live in a wide variety of habitats. They belong to the order Hymenoptera, and family Formicidae. There are more than 8800 described species that occur throughout the world. They have large heads, segmented antennae, and powerful jaws and undergo complete metamorphosis. In general, ants live typically in structured nest communities, forming nest sites in close proximity to moisture and food, underground, in ground-level mounds, or in trees. Among ant species, there is a wide range of interesting behaviors displayed. Many species are mutualistic, where they develop interactions with other insects and/or plants. Other species display parasitic relationships among each other. Still other species exhibit predatory behaviors. This book contains contributions written by experts in their respective fields and targets a wide audience. It is highly recommended as a valuable resource for general biologists, entomologists, ecologists, zoologists, and students and teachers in training in this subject matter. 92 pp. Englisch.…

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Thermomechanics is a scientific discipline which investigates the behavior of bodies under the action forces and heat input.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the field of computers and with the advent of the internet, the topic of secure communication has gained significant importance. The theory of cryptography and coding theory has evolved to handle many such problems. The emphases of these topics are both on secure communication that uses encryption and decryption schemes as well as on user authentication for the purpose of non-repudiation. Subsequently, the topics of distributed and cloud computing have emerged. Existing results related to cryptography and network security had to be tuned to adapt to these new technologies. With the more recent advancement of mobile technologies and IOT (internet of things), these algorithms had to take into consideration the limited resources such as battery power, storage and processor capabilities. This has led to the development of lightweight cryptography for resource constrained devices. The topic of network security also had to face many challenges owing to variable interconnection topology instead of a fixed interconnection topology. For this reason, the system is susceptible to various attacks from eavesdroppers. This book addresses these issues that arise in present day computing environments and helps the reader to overcome these security threats. 68 pp. Englisch.…

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Organochlorines (OC) are organic molecules with chlorine in their structure. There is a large number of organochlorine compounds known. Large amounts of chlorinated organic compounds are produced for industrial, agricultural, pharmaceutical, household purposes, etc. In many studies, the main focus is on OC that have been evaluated as environmental contaminants with toxic effects on humans. Different types of organochlorines have been produced throughout the world. Some of the most popular classes are organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), dioxins, chlorobenzenes, chlorophenols, chlorinated alkanes, etc. Organochlorine compounds are very stable. Generally, they are molecules of moderate polarity (low solubility in water). This makes OCs easily soluble in fats. They are found in almost all environments: air, water, soil, sediments and biota samples. They can spread out easily in different geographic altitudes and latitudes. Volatile and semi-volatile OCs have the ability to travel far distances from the place where they were used. Some studies have reported some organochlorines in the North Pole at the same levels as the areas where they were produced or applied. They have the ability to bioaccumulate easily in biota. Passing through the food chain levels, they increase their concentrations (biomagnifying). The main access pathways for OCs to the human body are through foods and exposures. Generally, they display their effects after a relatively long period of exposure. This is the main reason why they were produced and used for a long time before their production and use was banned. The most important health effects that organochlorines can cause are: mutagenic, endocrine-disruptor, carcinogenic and central nervous or peripheral disorders. After identification of the consequences, production of OCs and use was banned in many countries but their effects are still being seen many years later. 72 pp. Englisch. …

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Aging is characterized by functional decline in every organ due to several cellular, biological, and physiological changes over time. Molecular and cellular damages are gradually decreasing in the physical and mental capacities of the human body. Health results have shown that lifespan has dramatically increased during the twenty-first century. Increasing elderly population naturally deals with many health problems leading to a rise in health expenditure and labor loss. The good news is that the clinical trials in gene therapy have almost stopped and/or reversed human aging. Regenerative medicine can repair and reverse aging in all body cells. Thus, the body's own repair mechanisms may struggle with aging and age-related diseases. Research is promising and suggests that human aging will be eradicated on earth. 76 pp. Englisch.…

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Chronic kidney disease (CKD) is a world-wide known disease affecting up to 4% of the population with increasing figures in developing countries. Life expectancy of patients affected by CKD is shortened compared to the overall population and only a minority of patients reach end stage renal disease (ESRD) with the need for dialysis or renal transplantation; death overtakes dialysis. In nine chapters, this book focuses on different aspects related to the pathophysiology and clinical aspects of CKD, providing interesting insights into new and old biomarkers, allowing us to increase diagnostic and prognostic meaningfulness. In addition, chapters deal with new developments in glomerulopathies, but also aspects of the 'tubulocentric' shift will be beneficial for the open-minded reader.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As a strategic response to cognitive and CNS impairments, BCI is a theoretical outgrowth of several generations of endogenous devices for peripheral nerves, which have as a prime goal the direct replacement of lost neural function. In these earlier applications therapeutic intervention has been premised only on the restoration of signal generating capacity where nerve transmission is largely unidirectional and temporally sequenced. It is increasingly apparent, however, that the brain not only employs a very different type of syntax from that of peripheral nerves but also structures the semantic content of motor activity, fundamentally altering the conception of BCI as a therapeutic medium. The book presented here documents this change, proposing a multi-faceted strategy in which BCI therapy can restore the loss of multi-tiered, brain based motor function. 166 pp. Englisch.…

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Heart valves are the basic functional structure of the heart to obtain, sustain, and maintain blood circulations in the body without energy loss, allowing blood regurgitation or obstructing blood flow. There are two basic designs of heart valves: actively protected via subvalvular apparatus (atrioventricular valves) and passively strengthened (ventriculoarterial valves). The embryologic and morphologic development of heart valves is the key stage to continue normofunctional structure and physiological behavior. Fetal anomalies, embryologic defects, or non-development pathologies may damage the structure of heart valves and cause functional deterioration at different grades. In this book, we have focused on specific pathologies, which require special knowledge and treatment modalities. 162 pp. Englisch.…
