Abstract: 随着全球范围内能源的紧缺,电动汽车充电设施的建设得到各国政府的支持。为了提高电网企业在充电设施建设与运营中的效益,论文针对贵阳市的城市特点以及民用汽车发展状况,首先采用BP神经网络对贵阳市电动汽车保有量进行了预测。根据预测得出的贵阳市民用汽车保有量的增长趋势,对贵阳市的充电设施的运营模式进行了研究,并对贵阳市电动汽车充电设施的建设方案与运营管理模式进行了建议。
With the decrease of energy around the world, the development of electric vehicle has been app- roved in many countries, and the construction of charging facilities have also been supported by the go- vernments. In order to improve the efficiency of the power grid, the forecast on the ownership of the electric vehicle in Guiyang was investigated firstly, then the business mode of the charging faculties was investigated. Finally the strategy for the business mode of charging faculties was presented, which can improve the effi- ciency of the power company.

不同分级标准对高背景值农田土壤重金属质量评价的差异性分析——以尤溪县为例
Different Classification Standards of High Background Values of Farmland Soil Quality Evaluation of Heavy Metals Analysis of the Differences—In Youxi County
 [PDF]


Advances in Geosciences (AG) , 2014, DOI: 10.12677/AG.2014.44027
Abstract:
本文选用当前我国现行的土壤环境质量标准、土壤养分分级标准、环境背景值和人体健康风险评价限制四种标准值对矿区农田土壤质量进行评价,同时综合指数评价法对比评价农田土壤重金属污染现状。结果表明:由于国家土壤环境质量标准、土壤养分分级标准值较低,导致区域整体评价结果较差,均无法给予当地农田土壤生态质量正确的评估。以省级区域环境背景值上限值为标准进行评价,7种重金属仍均有超标,其中铜、锌、镉、铅、汞变异系数较大,分别为131%、137%、111%、237%和103%。基于现场调研结果,采用人体健康风险评价法,整体上尤溪县的基本农田土壤受到了轻度污染,健康总风险指数平均值为0.583,达到慢性参考剂量。
This paper selected the existing soil environmental quality standard GB, soil nutrient classification standard, environmental background value and limit of four human health risk assessment standards of our country to evaluate farmland soil quality, and comparatively evaluated the heavy metal pollution’s situation of farmland soil by synthesizing index evaluation method. The results showed that due to soil environmental quality standards of the state, soil nutrient grading standard is low, leading to bad evaluation results of regional overall assessment, and the right evaluation of ecological quality of the local farmland soil cannot be given. Evaluating with the standard of the provincial level upper limit of regional environmental background values, there were still 7 kinds of heavy metal exceeding; the variable coefficient of copper, zinc, cadmium, lead, mercury was 131%, 137%, 111%, 237% and 103% respectively, which was large among others. Based on the research results, adopting the human health risk assessment method, it was found that the basic farmland soil was slightly polluted in Youxi County; the average total health risk index was 0.583, reaching chronic reference dose.

 [PDF]

Statistics and Applications (SA) , 2015, DOI: 10.12677/SA.2015.42011
Abstract:
本文基于Smirnor-Shevlyakov在2014年针对位置参数已知为0的稳健尺度估计(即改进的中位数绝对偏差FQn),提出了位置参数未知时的稳健尺度估计(称之为广义中位数绝对偏差GMAD)。数据分析表明:FQn在位置参数未知时不稳健,但GMAD估计在位置参数为0以及未知时均稳健。
Robust scale estimation with unknown location parameters which is called general median absolute deviations (GMAD) was proposed based on a robust scale estimation with location parameters of 0 (improved median absolute deviations FQn) given by Smirnor-Shevlyakov in 2014. The data analysis showed that FQn loses robustness when location parameters are unknown, but GMAD is robust when location parameters are zero or unknown.

Abstract: 本研究以272名大学生为被试,采用青少年时间管理倾向量表和学习动机量表对大学生时间管理倾向与学习动机之间的关系进行调查探究。研究结果表明:1) 女生的外生动机水平显著高于男生;2) 时间管理倾向高分组的学习动机水平显著高于时间管理倾向低分组,说明时间管理倾向水平较高的大学生有较强的学习动机;3) 时间管理倾向与学习动机之间呈显著正相关,时间管理倾向的三个维度对学习动机有一定的解释和预测能力。
The research uses a sample of 272 university students to explore relations between university stu- dents’ time management disposition and leaning motivation with Adolescence Time Management Disposition Scale and the revised Working Preference Inventory scale. There are some conclusions: 1) The level of in- trinsic motivation of females was higher than that of males; 2) The students who get higher capability of time management have higher levels of learning motivation; 3) There were significant relations between university students’ time management disposition and learning motivation, and three senses of time management can partly explain and predict the changes of leaning motivation.

Abstract:

微小RNA(microRNA, miRNA)是一类内源性小分子单链RNA,在细胞增殖、分化、凋亡尤其是肿瘤发生发展等生理病理过程中发挥重要作用。miR-21 是研究最早也是较特殊的miRNA 之一,其在几乎所有的实体肿瘤包括胰腺癌中高表达。miR-21 通过作用于靶基因调控胰腺癌发生发发展,在胰腺癌细胞增殖、分化、迁移、侵袭以及肿瘤耐药性等起发面关键作用,有望成为胰腺癌诊断、治疗以及判断预后的潜在的生物标志物,有着潜在的临床应用价值。
MicroRNAs (miRNAs) are a class of single-stranded, evolutionary conserved, noncoding RNA molecules,which play important roles in various physiological or pathological processes, such as cell proliferation, differentiation,apoptosis, and especially tumorigenesis. All of them, miR-21 is one of the first studied and most special miRNAs as it is over expressed in nearly all of soil tumors. miR-21 has been shown to regulate the progression of pancreatic caner by targeting tumor suppressor or oncogenes, playing a key role in cell proliferation, differentiation, migration, invasion and drug resistance of pancreatic cancer. Therefore, miR-21 will possibly be a potential biomarker for diagnosis, therapy and prognosis of pancreatic cancer, showing potentially clinical value.

 [PDF]

Advances in Clinical Medicine (ACM) , 2014, DOI: 10.12677/ACM.2014.43009
Abstract:
WNK1是WNK家族中第一个被发现的成员,WNK1有多个转录起始位点,在不同的组织有不同的转录产物。进一步的研究发现,WNK1基因1号内含子大片段缺失可导致Gordon综合征。WNK1是肾脏中多个离子转运体和通道的调控蛋白,在维持肾脏钾钠氯离子平衡以及血压调控中起非常重要的作用,因此,WNK1基因被认为是原发性高血压的致病候选基因,并且WNK1的基因多态性可能与普通人群患原发性高血压的遗传易感性相关。本文综述了WNK1的来源、结构与功能,从不同层次阐述了WNK1与原发性高血压的相关性,目的在于指导降压药的临床用药方案及预测其药效。
WNK1 was the first member found in WNK family; it has multiple transcription start sites and dif-ferent transcription products in different tissues. Further researches found that the deletion of Intein-1 in WNK1 gene can lead to Gordon syndrome. WNK1 is a regulatory protein of the renal iron transporters and channels, and plays a very important role in maintaining renal potassium, sodium and chlorine ions balance as well as the regulation of blood pressure, so the WNK1 gene is considered a key genes for essential hypertension. In addition, the WNK1 gene polymorphism may be linked to the susceptibility of the essential hypertension in general population. This review shows the source, structure and function of the WNK1, and investigates the correlation between primary hypertension and WNK1 aimed at guiding anti-hypertensive drugs clinical drug regiments and forecasts.
