Water in the proximity of a surface (interfacial water) is abundant on the earth. It is involved in various physical and chemical processes and crucial for biological function. Despite numerous studies of interfacial water, systematic analysis of its properties is missing in scientific literature. This book is a first comprehensive review of experimental and simulation studies of water in various confining environments, such as hydrophilic and hydrophobic surfaces, surfaces of biomolecules, porous media, etc. Systematic analysis of interfacial and confined water is based on the firm physical ground, which accounts for variety of the thermodynamic states of water near the surface, surface pha...
The story of the most abundant substance on Earth, from its origins in the birth of stars billions of years ago to its importance in the living world. Water is so ubiquitous in our lives that it is easy to take for granted. The average American uses ninety gallons of water a day; nearly every liquid we encounter is mostly water--milk, for example, is 87 percent water. Clouds and ice--water in other forms--affect our climate. Water is the most abundant substance on Earth, and the third-most abundant molecule in the universe. In this lavishly illustrated volume, science writer Jack Challoner tells the story of water, from its origins in the birth of stars to its importance in the living world....
Biological activity for most living organisms is at its highest where the percolation transition occurs; hence, finding such temperature range was of utmost importance. After having found such temperature interval, i.e., between 310K and 330K, conformational studies were performed on full-length human and rat islet amyloid polypeptide, hIAPP and rIAPP respectively, by MD simulations both for the reduced and oxidized IAPP moieties. Studying the monomeric forms of two very similar polypetides that present different amyloidogenic properties could shed light on the aggregation mechanism of human islet amyloid polypeptide; in fact, after hundreds of nanoseconds, above the percolation transition temperature, oxidized hIAPP 'folded”'into a compact structure that was about 10% smaller than the average value of the radius of gyration. Further studies were carried out on some in silico mutated hIAPP moieties in order to pinpoint key residues involved in the 'folding' of hIAPP. Three conditions were needed in order to observe this compact state: the presence of the disulfide bond; the absence of the P28 residue, found in rat IAPP; presence of aromatic residues, in particular F23.
An authoritative summary of state-of the-art research contributions from the world's leading scientists.
Conscience on Trial reveals the startling story, kept secret for sixty years, of ordinary citizens caught up in the elaborate machinery of political terror in Stalinist Ukraine. In 1952, fourteen poor, barely literate Seventh-Day Adventists living on the margins of Soviet society were clandestinely tried for allegedly advocating pacifism and adhering to the Saturday Sabbath. The only written records of this trial were sealed in the KGB archives in Kiev, and this harrowing episode has until now been unknown even within the Ukraine. Hiroaki Kuromiya has carefully analyzed these newly discovered documents, and in doing so, reveals a fascinating picture of private life and religious belief under the atheist Stalinist regime. Kuromiya convincingly elucidates the mechanism of the Soviet secret police and explores the minds of non-conformist believers -precursors to the revival of dissidence after Stalin's death in 1953.
This book presents current investigations in the field of mathematical modeling and simulation to support the development of intelligent information systems in domains such as ecology and geology, manufacturing, project management, and safety of distributed information systems. The book will be of interest to developers of modern high-tech software complexes for situational control centers, based on mathematical modeling and simulation methods. In addition, it will appeal to software engineers and programmers, offering them new implementation and application methods. Gathering the latest research, prepared by leading scholars, and identifying promising new directions for solving complex scientific and practical problems, the book presents selected outcomes of the 14th International Scientific-Practical Conference, MODS2019, held in Chernihiv, Ukraine, on June 24 to 26, 2019.
