白天小睡似乎与忙碌文化背道而驰,但在学习期间小睡可以非常有效地促进整体健康和学习状况。下面我们来详细了解一下午休的最佳方式。设置计时器如果你曾经打了几个小时的盹,但醒来时却感到疲惫不堪,你就会知道,你睡得太多了。专家建议设置一个计时器。对于午睡来说,20到30分钟是理想的时长。如果哪一天特别忙碌,即使是(午休)10分钟也有助于减轻压力。

We have theoretically analysed the perimeter-area relation and simulated its application to measuring the fractal dimension of fracture surfaces. It is proved that the fractal dimension D obtained by slit island method (SIM) is related to the dependence of measured area A(delta) of the slit island on yardstick delta. So in some cases, the dimension D obtained by SIM is dependent on yardstick and in other cases independent on yardstick delta. But in all cases, when delta-->0 the dimension D obtained by SIM approaches the real fractal dimension (similar dimension) of 'coastline' of the island. We analysed some experimental data and found some new and interesting characteristics of crack propagation in steels.

With the formation of the socialist legal system with Chinese characteristics, China pays more attention to the scientificity and the quality of legislation, starting the assessment of the effect of implementation of the law after legislation conducted by an independent third-party institution with scientific methods. The third-party legislative post-assessment can overcome the drawbacks of self-assessment, realizing the public participation better, which makes results of the assessment more objective, neutral and fair. The neutrality of assessment and scientificity of the method should be adhered in the construction of third-party legislative post-assessment in China, while improving public participation as well as the assessment indicators system and quality control system with the introduction of specific legal norms.

Calmodulin (CaM), widely distributed in almost all eukaryotic cells, is a major intracellular calcium receptor responsible for mediating the Ca2 + signal to a multitude of different enzyme systems and is thought to play a vital role in the regulation of cell proliferative cycle[1，2]. Recently, many studies showed that CaM is also present in extracellular fluid such as cell culture media and normal body fluid and has been reported to stimulate proliferation in a range of normal and neoplastic cells, apparently acting as an autocrine growth factor[3-11]. In 1988, Crocker et al reported for the first time that addition of extracellular pure pig brain CaM could promote DNA synthesis and cell [7]proliferation in K562 human leukaemic lymphocytes[7].After that, more and more research was done on extracellular CaM and evidences demonstrated that extracellular CaM could also stimulate cell proliferation in normal human umbilical vein endothelial cells[5], keratinocytes[4], suspension-cultured cells of Angelica Dahurica, etc[6]. CaM is a monomeric protein of 148 amino acids that contains four homologous Ca2 + -binding domains. CaM has been highly conserved throughout the evolution. Only 1 out of 148 amino acids of human CaM is different from that of fish CaM. Complementary DNAs encoding rat, eel, chicken, human, and trypanosome CaM have been cloned.
