This chapter first of all reviews the organizational theory of new institutional economics in order to pave the way in literature and methodology for the study of water governance structure. Then, it proceeds with the basic implications of water governance and finds that the most important output of water governance is to ensure water security. The collective actions for this purpose result in ...
Background: Nanomicrobial cellulose is an important biopolymer with a three-dimensional structure that is produced by some microorganisms and has been widely used in medicine. One of the unique properties of microbial cellulose is its very high water absorption, which can be used to produce modern wound dressings. But after drying, it’s three-dimensional structure collapses and the amount of wa...
Pauling and Miller have independently proposed that the presence of an anesthetic gas in tissue induces a cage-like arrangement of hydrogen-bonded water molecules. The theories recognize that most gas-hydrate crystals would not form at the temperature and pressure that exist during anesthesia and propose that other components of tissue such as protein should have a stabilizing effect. Measureme...
Proteins have evolved to use water to help guide folding. A physically motivated, nonpairwise-additive model of water-mediated interactions added to a protein structure prediction Hamiltonian yields marked improvement in the quality of structure prediction for larger proteins. Free energy profile analysis suggests that long-range water-mediated potentials guide folding and smooth the underlying...
Recent experimental and theoretical applications of x-ray spectroscopies to liquid water shed new light on the hydrogen bonding network. The interpretation of the x-ray data questions the established understanding of liquid water. Two new system experts have joined the NSC forces. The structure of the first coordination shell in liquid water. Illustration by Hirohito Ogasaware. The construction...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...
