在这篇论文，我们在场为有斜面的一条高速公路上的交通流动的一个新宏模特儿基于存在当模特儿。我们使用新模型在早上匆忙时期和晚上匆忙时期期间在主要道路交通上学习 on-off-ramp 的效果。数字测试证明在二个匆忙时期期间，这些效果经常是不同的并且与主要道路交通的地位有关。如果主要道路交通流动是一致的，当主要道路密度在二批评价值之间时，那么，斜面总是生产定期而不断被迫停的交通，并且当主要道路密度是时，斜面在主要道路交通上有小效果不到更小的批评价值或比更大的批评价值大。如果小不安出现在主要道路上，斜面可以导致定期而不断被迫停的交通，或减轻或甚至消除，在不同情形下面定期而不断被迫停的交通。这些结果与真实交通一致，它证明新模型是讲理的。

The tools of synthetic biology can be used to engineer living biosensors that report the presence of analytes. Although these engineered cellular biosensors have many potential applications for deployment outside of the lab, they are genetically modified organisms (GMOs) and are often considered dangerous. Mitigating the risk of releasing GMOs into the environment while enabling their use outside a laboratory is critical. Here, we describe the development of a biosensing system consisting of a synthetic biological circuit, which is engineered in Escherichia coli that are contained within a unique 3D-printed device housing. These GMOs detect the chemical quorum signal of Pseudomonas aeruginosa, an opportunistic pathogen. Using this device, the living biosensor makes contact with a specimen of interest without ever being exposed to the environment. cells can be visually analyzed in the field within culture tubes, or returned to the lab for further analysis. Many biosensors lack the versatility required for deployment in the field, where many diseases can go undiagnosed due to a lack of resources and equipment. Our bioassay device utilizes 3D printing to create a portable, modular, and inexpensive device for the field deployment of living biosensors.

目的描述三个大洲13个国家儿童青少年水和其他饮料的摄入。方法由13个横断面研究中获得3611名4-9岁儿童和8109名10-17岁青少年的数据,其中男性比例为47%。三个国家使用分层整群抽样设计随机抽取学校班级。其他国家使用一种定量方法随机抽取研究对象。连续7天使用专门的液体记录表获得摄入的液体种类的细节。结果全部样本中,观察得出平均摄入量最高的是水(738±567毫升/天),接下来是牛奶(212±209毫升/天),常见软饮料(RSB)(168±290毫升/天)和果汁(128±228毫升/天)。地理位置接近的国家被发现是摄入水、常见软饮料或热饮居多的模式。大多数国家中,青少年与儿童相比牛奶摄入量显著下降,而常见软饮料和热饮摄入量增加。观察到的最为一致的性别差异是在两个年龄段中男性常见软饮料摄入量显著高于女性。结论总体来看,水是儿童青少年消费量最大的液体,但是实质上不同国家之间其他种类液体的摄入量是不同的。因为常见软饮料的摄入量巨大,在一些国家甚至高于水的摄入量,应该采取措施改善儿童青少年的液体摄入习惯。

Techniques of gully-specific debris flow hazard assessment develope d in four periods since the end of the 1980s have been discussed in the present paper. The improvement for the empirical assessment method is the sectionalized function transformation for the factor value, rather than the classified logical transformation. The theoretical equation of the gully-specific debris flow haz ard is expressed as the definite integral of an exponential function and its num erical solution is expressed by the Poisson Limit Equation. current methods for assessment of debris flow hazard in china are still valid and practical. The fur ther work should be put on the study of the reliability (or uncertainty) of the techniques. For the future, we should give a high priority to the relationship b etween debris flow magnitude and its frequency of occurrence, make more developm ents of prediction model on debris flow magnitude, so as to finally reach the go al of assessing the hazard of debris flow by theoretical model, and realize both actuality assessment and prediction appraisal of debris flow.

coriolus versicolor has been reported to have biological activities such as anticancer, antibacterial, antibiotics and immunopotentiation. The authors tried to ferment using lactobacilli associated with various biological functions and expected that fermented extract by lactobacilli will be superior to non-fermented extract in antioxidant activity. c. versicolor was extracted with 70% ethanol and then it was fermented by Lactobacillus acidophilus KcTc3164 and Lactobacillus plantarum KcTc3099, respectively. 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity, superoxide dismutase (SOD)-like activity and tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays were performed. DPPH scavenging activity of fermented extract by L. acidophilus was higher than fermented extract by L. plantarum and antioxidant effect of fermented extract was 20%-30% higher than non-fermented extract. SOD-like activity was represented 18% in fermented extract by L. acidophilus, and was 27% in fermented extract by L. plantarum higher than non-fermented extract. As a result, this study suggests that it may need an efficient protocol for dominant bio-physiological activities such as extract volume or appropriate working volume of cultured cell or mixture condition. The fermented c. versicolor extract should provide with useful antioxidant agent in the human skin.

Soil erosion by concentrated flows in agricultural areas is an important process affecting soil losses and landscape degradation. The main factors controlling concentrated flow erosion include the erodibility of materials, soil use and management, climate, and watershed topography. In this paper, two topographic indices, closely related with mathematical expressions suggested by different authors, are used to characterize the influence of watershed topography on gully erosion. The AS1 index is defined as the product of the watershed area and the partial area-weighted average slope. The AS2 index is the product of the watershed area and the length-weighted average swale slope. Using different ephemeral gully erosion databases, a high correlation was found between the topographic indices and the volume of eroded soil. The accuracy of different methods for field measurement of ephemeral gullies was evaluated to ensure that the relation between erosion and topographic indices is not affected by assessment errors. The resulting relation are useful to assess soil losses from gully erosion, to identify the most susceptible watersheds within large areas, and to compare the susceptibility to gully erosion among different catchments. This information also can be important to study the response of natural drainage network systems to different rainfall inputs.
