Wetlands are the ecotonal or transitional zones between terrestrial and aquatic ecosystems where the water table is usually at or near the surface of the land, which is covered by the shallow water (Mitsch & Gosselink, 1986). Due to these characteristics, wetlands provide opportunities for adaptations to different plant and animal species with high diversity of life-forms. Thus wetlands are among the most biologically diverse and...

Autoimmune disease represents a group of more than 60 different chronic autoimmune diseases that affect approximately 6% of the population. It is the third major category of illness in the United States and many industrialized countries, following heart disease and cancer. Autoimmune diseases arise when one’s immune system actively targets and destroys self tissue resulting in clinical disease. Common examples include Systemic Lupus...

Chapter Title i Applied Behavior Analysis for TeachersWe prepared the first edition of Applied Behavior Analysis for Teachers over 20 years ago because we needed a technically sound, systematically organized, and readable text for our own students. We want students to understand concepts of applied behavior analysis and also to know how to apply those concepts in classrooms and other settings. Applied behavior analysis can make a difference;...

E' opinione comune che le leggi dell'universo scoperte dalla scienza siano in conflitto con quelle imperscrutabili di Dio. La contrapposizione tra fede e scienza rappresenta uno dei dilemmi più laceranti del nostro tempo; un dramma che conobbe il suo primo, controverso atto con Galileo Galilei. In questo saggio appassionato, che si legge come un vibrante manifesto, Antonino Zichichi smentisce tale contrapposizione e la ribalta: "Non esiste...

Currently, imperfection sensitive shell structures prone to buckling are designed according the NASA SP 8007 guideline using the conservative lower bound curve. This guideline dates from 1968, and the structural behaviour of composite material is not appropriately considered, in particular since the imperfection sensitivity and the buckling load of shells made of such materials depend on the lay-up design. This is not considered in the...

Historians, scientists, and researchers have been fascinated by the diaphragm for many centuries. Homer first described Trojan War battle wounds with reference to the diaphragm in the 9th century B.C. From 500-430 B.C., Empedocles of Agrigentum was one of the first people to study the physiology of respiration. In this early period of medical knowledge, however, the purpose of the diaphragm bewildered scientists. Hippocrates observed the...

Clinical neurophysiology is an area of medical practice focused primarily on measuring function in the central and peripheral nervous systems, the autonomic nervous system, and muscles. The specialty identifies and characterizes diseases of these areas, understands their pathophysiology, and, to a limited extent, treats them. Clinical neurophysiology relies entirely on the measurement of ongoing function—either spontaneous or in response to...

Although the technologies on chiral/enantiomer separation and stereoselective analysis have matured in the past ca. 20 years, the development of new, even more advanced chiral separation materials, mechanisms and methods still belong to the more challenging tasks in separation science and analytical chemistry. An analysis of recent trends indicates that capillary electrophoresis (CE) can show real advantages over chromatographic methods in...
