Abstract We investigate the dissolution mechanism of cellulose using molecular dynamics simulations in both water and a mixture solvent consisting with Na $$^+$$ + , OH $$^-$$ - urea. As first computational study its kind, we apply periodic external forces ...

Using lipid-impregnated porous cellulose membranes as biomimetic barriers, we tested the hypothesis that to afford effective transmembrane transfer of proteins and nucleic acids, the vehicle solvent should be able to dissolve both the biopolymers and the lipids. While the majority of solvents dissolve one or the other, ethanol and methanol were found to dissolve both, especially if the protein ...

To enhance the contact between electrolyte (source of O2−) and carbon fuel in solid oxide–direct cells (SO-DCFCs), molten metals salts were used anode chamber. Oxygen ions can dissolve be transported medium to three-phase boundary reach oxidize particles. improve sluggish kinetics electrochemical oxidation carbon, same media act as redox mediators. Moreover, using a liquid metal/salt anode, tol...

the idea of systems analysis and mathematical modeling for formulating and resolving river pollution issues is of relatively recent vintage and has been applied widely in the last 3 decades. the present study illustrates the utility of beck-modified khanna–bhutiani model (bmkb) to determine the pollution load due to the presence of organic matter in river ganga from its course from devprayag to...

The detection of dissolve transition is more difficult than detecting fade in and fade out. In this transition, the last frames in the previous shot fade out and the beginning frames in the next shot fade in i.e. the overlapping of fade out and fade in occurs. The dissolves may be of three or more number of frames. In some videos very short dissolve of even three frames also occurs. So, there a...

introduction: diabetes mellitus is a global public health issue that has a prevalence of between 5-8% in different parts of iran. one of the most serious complications of diabetic foot ulcer and chronic complications of diabetes mellitus is one of the leading causes of morbidity and amputation in patients with diabetes. on the other hand, amputations in patients with diabetes are three-year sur...

To get something you never had……you have to do did. I found that nothing in life is worthwhile unless take RISKS……NOTHING. Ease…..is a greater threat progress than hardship. Thomas Edison conducted 1000 experiments. Because the and first – was light bulb. Every failed experiment one step closer success So what feel passionate about. Take chances.

The aim of this study was to assess the influence of trout farm effluents on water quality parameters in the Dohezar Stream. In this study two trout farms and 7 stations were selected and physiochemical of water, including air and water temperatures, dissolved oxygen concentration (DO), pH, electrical conductivity (EC), water flow and biochemical oxygen demand (BOD) were measured every 30 days ...
