The hydration shell structure of human serum albumin (HSA) and HSA adsorbed on a surface of highly disperse silica in a weakly polar solvent (chloroform) or with various addition of this solvent was studied by 1 H NMR spectroscopy and layer-by-layer freezing-out of a liquid phase. The influence of chloroform can result in changes in the ratio of volumes of internal regions of protein globule characterized by different hydration levels and filled up with structured water unfrozen at T < 273.
The development of personal mobile microprocessor gadgets, computer mathematics systems and interactive online supplements allow victoriousness in the initial process by algorithms of symbolic mathematics, numerical methods and hard functional graphical. The article shows a choice of options for engineering development of a standard task of assigning a normal depth in line with a trapezoidal living process.
Discernible shortcomings of symbolic and numerical algorithms in the development of tasks in the CAS MAXIMA system. The article presents a visualization and method of a simple iterative solution of tasks. An assessment of the accuracy of the result was carried out using the graphical method. In parallel, the solution of the tasks is taken from the Web-interface to the on-line service of the CAS MAXIMA system on the CESGA server.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
