The eyes are the source of knowledge acquisition and channel for transmitting information. In modern society, due to lack self-awareness primary secondary school students, parents teachers cannot remind them all time. Once bad reading writing habits formed, it is difficult change them. vicious cycle day after leads many students wearing glasses prematurely. It not only inconvenient in life but ...

Wind and heavy rain can have a devastating effect on crop production if they occur late during the life cycle of the plants. They often flatten the crop on the ground, leaving seed and other harvestable products at the mercy of soil moisture and pathogens and inaccessible to mechanical harvesting machinery. However, farmers will not worry much if a storm of similar strength hits a crop earlier ...

Abstract Background Over the last 200 years, courses of most European rivers have experienced significant irreversible changes. These changes are connected to different kinds anthropogenic river use and exploitation, which varied from running water mills rafting large-scale hydroelectric power plants, industrial withdrawal flood protection measures. Today, in developed countries, quality ecolog...

We consider the stability of transonic contact discontinuity for two-dimensional steady compressible Euler flows in a finitely long nozzle. This is first work on mixed-type problem across as free boundary nozzles. start with Euler-Lagrangian transformation to straighten new coordinates. However, upper nozzle wall subsonic region depending mass flux becomes after transformation. Then we develop ...

Glass microprobes were used to measure the stiffness of the flagella of Triton X-100-extracted rat sperm models. The sperm models were treated with 50 microM sodium vanadate and 0.1 mM Mg-ATP to evaluate the stiffness of the passive flagellar structure without the influence of the dynein motor proteins. The passive stiffness was determined to be 4.6 (+/- 1.1) x 10(-19) N x m(2). Rat sperm model...

Many think that the perpetrators who died their actions martyrs. However, concept must be seen further, because not just sacrificing one's life, but also life manifests faith t...

The 1000 MW hydro-generator unit has huge geometrical dimensions and requires high installation accuracy. control of its deviation will directly affect the quality operational performance rotor eccentricity is one core problems faced in operation giant unit. This paper presents a method to calculate asymmetric magnetic field by means transient finite element calculation reveal effect generator ...
