Wonders Of Water: The Hydrogen Bond In Action
The book presents the fantastic world of water in all its different forms, from liquid to ice and snow. This book is amply illustrated with a large number of beautiful pictures with. Water plays a unique role in chemistry. The special properties of water are due to hydrogen bonding between the H2O molecules. The hydrogen bond is of fundamental importance in biological systems since all living matter has evolved from and exists in an aqueous environment, and hydrogen bonds are involved in most biological processes. There is a hundred times more water molecules in our bodies than the sum of all the other molecules put together.The unique properties of water are of great importance in our daily...
Snow, Ice and Other Wonders of Water
The book illustrates the fascinating world of the different forms of water - from ice and snow to liquid water. The water molecule, H2O, is the second most common molecule in the Universe (behind hydrogen, H2) and ice is the most abundant solid material. Snow and ice appear in a countless large number of different shapes and with properties which can be quite different. Detailed knowledge of the properties of snow is of great importance for the Sami people involved in reindeer herding and several hundred names are used to characterize the different types. The properties of ice and liquid water are very special and unique in several respects. In contrast to most other substances, the density ...
Structure And Action Of Molecular Chaperones: Machines That Assist Protein Folding In The Cell
This unique volume reviews the beautiful architectures and varying mechanical actions of the set of specialized cellular proteins called molecular chaperones, which provide essential kinetic assistance to processes of protein folding and unfolding in the cell. Ranging from multisubunit ring-shaped chaperonin and Hsp100 machines that use their central cavities to bind and compartmentalize action on proteins, to machines that use other topologies of recognition — binding cellular proteins in an archway or at the surface of a 'clamp' or at the surface of a globular assembly — the structures show us the ways and means the cell has devised to assist its major effectors, proteins, to reach and maintain their unique active forms, as well as, when required, to disrupt protein structure in order to remodel or degrade. Each type of chaperone is beautifully illustrated by X-ray and EM structure determinations at near- atomic level resolution and described by a leader in the study of the respective family. The beauty of what Mother Nature has devised to accomplish essential assisting actions for proteins in vivo is fully appreciable.
Water
Around 71% of the Earth's surface is covered in water. In this Very Short Introduction John Finney explores the science of water, its structure and remarkable properties, and its vital role for life on Earth.
Electron and Magnetization Densities in Molecules and Crystals
The interest of describing the ground state properties of a system in terms of one electron density (or its two spin components) is obvious, in particular due to the simple physical significance of this function. Recent experimental progress in diffraction made the measurement of charge and magnetization densities in crystalline solids possible, with an accuracy at least as good as theoretical accuracy. Theoretical developments of the many-body problem have proved the extreme importance of the one electron density function and presently, accurate methods of band structure determination become available. Parallel to the diffraction techniques, other domains of research (inelastic scattering, ...
Saving Lakes - The Urban Socio-cultural And Technological Perspectives
'Cities are not just brick and mortar; they represent the dreams, aspirations, and hopes of societies.'UN Habitat (2008)Urban lakes are part of many of the cities we live in. They are often intricately bound with the city's social fabric, valued for direct utility purposes such as drinking water provision, or for their aesthetic, historical, cultural, and religious significance. However, oftentimes in spite of their unique spatial, socio-cultural, and economic value and 'relationship' with the city, urban lakes end up as receptacles for waste, or are infilled for development.This book traces the socio-cultural and technological dimensions at play for the protection and remediation of a tropi...
Nobel Prizes And Nature's Surprises
Each year the Nobel Prizes in the natural sciences reveal amazing discoveries. New milestones in the relentless advance of science are identified. The growth of knowledge and its evolution can be researched in the Nobel archives where nominations are kept secret for 50 years after the awards have been made. They represent a treasure for real-time assessment of science. Norrby's earlier book, Nobel Prizes and Life Sciences (2010) examined the unique archival records until 1959.The present book takes us up to 1962, surveying a range of dazzling discoveries. All prizes in immunology are reviewed. Their impact on our capacity to control infectious diseases and transplant organs are highlighted. The Nobel year 1962 is exceptional in recognizing the most major advance in biology since Darwin in 1859 presented his theory of evolution. This was the dramatic discovery of the double-helix structure of DNA by Watson and Crick in 1953. The era of molecular biology had begun. Its explosive development continues into the present.
