This study is aimed at separating and identifying a new glycoprotein from sweet potato (SPG) and detecting its anti-colon cancer bioactivity. The SPG-56 was obtained by water extraction, isoelectric precipitation, chromatography and electrophoresis. The compositions of sugar and protein in SPG-56 were identified with high performance liquid chromatography and amino acid analyzer, and the antitumor...

Due to its high strength, good durability, concrete is widely used in various types of buildings and structures. With the continuous development of engineering and technology, all kinds of new, unique shape structure, the use of mass concrete structure is more and more widely. But big volume concrete block, its thermal performance is poorer, inside the concrete hydration heat accumulation is difficult...

Numbers of neighbor embedding (NE) methods have been proposed, which use the image content metric based on the distance values such as Euclidean distance between the input image patch and the image patches in the training set to find the nearest neighbors. In contrast to these approaches we propose to use image content metric that uses the most effective singular values of the patch of interest. Singular...

The hot deformation behavior of 2124 aluminum alloy hot-rolled sheet was investigated by means of hot compression test using Gleeble thermal simulation machine within the temperature range of 340-500° and strain rate range of 0.01-10s-1 with the maximum deformation degree set to 60%. The microstructure evolution during hot deformation was observed by optical microscope and transmission electron microscope...

Because of its simple structure formation, the material is easy to take, and its convenient construction, low cost, simple technology, various forms, masonry structure has been widely used in multistoried buildings, schools, hospitals and other civil buildings, and is one of the most common structure form in enormous quantity and wide coverage building engineering. Due to masonry structure has some...

EXB841 gets the shortcomings as lack of gate-voltage, excessiveness of over-current protection threshold and long soft-shutdown time etc. According to the shortages, some improved managements were given. By improving the power supply of the module, adding external gate-voltage molding circuit and changing the external zener, not only the output gate-voltage was boosted, but also the over-current protection...

By integrating the recursive and iterative thoughts commonly used in modeling fractals, an intelligent plant simulation technique is presented in the paper. With the technique, not only can the overall shapes and details of plants be controlled interactively by designing parametric fractals and parameterized growth process of fractals, but also the complexity in space and time of fractal-plants be...

This paper analyzes the dynamic magnetoelectroelastic behavior induced by a penny-shaped crack in a magnetoelectroelastic layer. The crack surfaces are subjected to only radial shear impact loading. The Laplace and Hankel transform techniques are employed to reduce the problem to solving a Fredholm integral equation. The dynamic stress intensity factor is obtained and numerically calculated for different...
