In order to study the popular curve shortening flow in the plane, Gage[3] has shown in 1983 the following inequality, if k is the signed curvature of a closed convex plane curve γ with length L and enclosing area A, then one gets Gage calls it an isoperimetric inequality in [3], but he does not show that the equality holds if and only if the curve γ is a circle, while as an isoperimetric-type inequality, one should prove this kind of result.

Gage稱(chēng)之為等周不等式，但他沒(méi)有證明其中等號(hào)成立當(dāng)且僅當(dāng)www.麻豆精品，γ為圓周男女性爱过程视频，而作為等周型的不等式是應(yīng)該證明這種結(jié)果的，本文我們利用單位速率外法向量流国产吞精口爆一区二区，通過(guò)努力證明了這種結(jié)果国产一级A片免费观看com，從而把Gage不等式加強(qiáng)成更加等周的形式。

And then, in this part, following the idea of Topping [51, 52], we will show an isoperimetric inequality (6.3.1) on surfaces of non-positive Gaussian curvature by means of the curve shortening flow on surfaces, this inequality can be considered as a generalization of the Banchoff-Pohl inequality in the Euclidean plane.

In this study, we found out that linalool, a small-molecule compound, could inhibit the growth of various human lymphocyte leukemia cell lines significantly. Meanwhile, it showed little toxicity to normal hematopoietic cells. To determine effects of linalool on the growth of a serious of human leukemia cell lines and normal hematopoietic cells and to explore its possible mechanisms, we employed various technologies, including MTT assay, Flow cytometry, Human Cancer PathwayFinder II Gene Array, Western Blot, RT-PCR and so on.

Methods The cognitive impairment rat model was induced by hypodermic D-galactose injection and half fat feeder (6 weeks), the Morris water maze was used to screen the model rats, which were divided randomly into 4 groups (12 rats in each group): the model group, the hydrochloricdonepezil group (0.4 mg/kg, weight, sic passim), the low-dose Huannao Yicong Fang group (7 g crude drug/kg), the high-dose Huannao Yicong Fang group (14 g crude drug/kg), they were treated respectively by intragastric administration. Besides, a control group of 12 rats was set up, they were given tales doses of distilled water. After 4 weeks, the behavior of the rats was detected, the contents of plasma P-selectin and PAI-1 were measured by ELISA, also the hemorrheology was measured.

Methods In cases of SAP with severe pancreatic and peripancreatic infection, open surgical debridement and drainage was done, and, about one week later, the drainage tubes were removed and a choledoscope was then used repeatedly to debride and wash out the necrotic and infected foci that were hard to drain out.

This paper gives the distribution of the Peynolds stresses, which shows that the flow near the wall at the exit is obviously nonisotropic and the maximal turbulence intensity is enough high to impact on the matching of the intake and the engine. The unsteady characteristics of the flow evince that the flow doesn't separate obviously.

This blowing fan has a hub connected to the rotating shaft of a motor and a number of blades mounted on the outside surface of the hub at fixed intervals to flow air in the centrifugal direction of the fan. Although this fan is produced in a shape of axial fan or diagonal fan by integrally forming the separate turbo blade on the tip or trailing edge of the rotor blade, the blowing noise can be reduced in addition to the increase in the entire wind quantity of the fan by embodying the optimum set angle of the turbo blade.
