In sea urchin zygotes and mammalian cells nuclear envelope breakdown (NEB) is not driven simply by a rise in cytoplasmic cyclin dependent kinase 1-cyclin B (Cdk1-B) activity; the checkpoint monitoring DNA synthesis can prevent NEB in the face of mitotic levels of Cdk1-B. Using sea urchin zygotes we investigated whether this checkpoint prevents NEB by restricting import of regulatory proteins in...

In this paper, we prove the local well-posedness of free boundary problem for incompressible Euler equations in low regularity Sobolev spaces, which velocity is a Lipschtiz function and surface belongs to $C^{\f32+\varepsilon}$. Moreover, also present Beale-Kato-Majda type break-down criterion smooth solution terms mean curvature surface, gradient Taylor sign condition.

Most people think of fiber as being the part of our food we can’t digest—but with the help of symbiotic bacteria in our guts, we can actually get some nutrition from the complex carbohydrates such as cellulose, hemicellulose, and pectin that make up plants’ cell walls. The bacteria produce an arsenal of enzymes that break down these carbs into simple sugars, which are then in turn fermented to ...

In this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for V47/660kW wind turbine operated in Manjil wind farm, Gilan province, Iran. According to the acquired data from Iran wind turbine industry, common faults of the wind turbine such as sensor fault...

The conversion of the cellulose into 5-HMF would experience three steps, cellulose to glycose, glycose to fructose and fructose to 5-HMF. Chloride ion can break down the hydrogen bond in cellucose, chromium can catalyze the isomerization of glycose to fructose, and the high temperature is helpful to cyclohydration of fructose to 5-HMF. In this paper, the sawdust has been directly degraded i...
