The notion of energetic complementarity can be a tool for energy resource managers to prioritize energy generation projects based on renewable resources in both interconnected and independent systems. As a tool in decision-making, it is important to know better the influence of energetic complementarity on the performance of hybrid systems especially with regard to energy shortages but also in relation to other parameters. In recent years, hydro PV hybrid systems have become a growing target of researchers and designers for the idea of installing photovoltaic modules on the water surface of reservoirs. Energetic complementarity has three components: time-complementarity, energy-amplitude and amplitude-complementarity. This paper is dedicated to the study of the influence of time-complementarity on the storage of energy through batteries in hydro PV hybrid systems. The method applied is in the literature and suggests the simulation of the system under study with the idealization of energy availabilities, to remove the effects of climatic variations and the characteristic intermittency of renewable resources. Simulations were performed with the well-known software Homer. The results provided the variations of the states of charge of the batteries as a function of different time-complementarities, indicating as expected better performances associated to higher time-complementarities. The results indicated that the cost of energy for a hybrid system with 28 batteries was equal to US$ 0.502 per kWh and that this cost increased as the time complementarity between energy resources moved away from the situation corresponding to full complementarity. The simulations also showed that the maintenance of the zero failure condition supplying the demands of the consumer loads requires that the load be reduced to 52% if the complementarity is reduced from the full complementarity to zero complementarity, with the cost of energy going from US$ 0.502 per kWh to US$ 0.796 per kWh.

原子力显微镜(AFM)有接触和轻敲两种工作方式,可以在气相和液相下工作.在液相工作状态下,浸没于水中的探针和样品表面会形成一层水化膜.在探针和样品表面形成的水化膜是否会对扫描图像产生影响以及产生何种影响是一个值得研究的问题.本文用原子力显微镜对1μm标准校正光栅在空气和水两种媒质中进行了图像扫描,扫描分别采用接触和轻敲两种工作方式.扫描图像显示,在液相工作环境中,水化膜在探针和样品表面的形成将严重影响轻敲工作方式所形成的图像,而接触方式的扫描图像基本不受影响.

To analyze the feasibility of application of composite material as the insulating material, it is necessary to have knowledge of some of its mechanical properties. An insulating material may suffer from the most different efforts, but the major applications suggest mechanical bending and compression tests because the insulation can be applied on roofs of homes, liners similar to, in the form of plates. Thus, the product is continually flexed. When the material is used on a floor, it suffers constant compressions over its use. For tests performed in this study, we used the ASTM D695-96 for compression, an example of literature. Using such a standard test, specimens were produced for compression test, with specimens made of cylindrical shapes, respecting the condition that the height of the specimen corresponds to twice the diameter of the base. Polyurethane castor without charge vermiculite and mass loads of 10%, 15% and 20% matrix： four specimens for each type of material were produced. The composites were tested in a universal testing machine at a speed of 2 mm/s. The results are average values of four test samples, and initially show the behavior of castor oil polyurethane during the compression test, which is detailed in the stress versus strain curve. The achieved results are promising, and detailed in this paper.

The electron density and temperature key properties of the neutral-magnetized plasma in the solar corona, which are predicted with a novel model, provide an interesting window along the whole solar cycle. In this work, we test the quantitative validity of the model and prove that the Coronal density and Temperature (COdeT) is reliable. Furthermore, this work contrasts the COdeT model results with alternative observational remote and in-situ datasets during the simplest conditions of the quiescent corona near the solar minimum. This successful outcome/validation of the COdeT model allowed a good qualitative density and temperature retrieval in the solar corona covering a large portion of time interval from solar cycles 23 and 24.

印刷电子学为设计低成本的电子产品提供了一个广阔的前景。在未来几年内,采用印刷技术,在低温条件下使用纳米材料可能会带来印刷电子产业的变革。印刷电子产品可包括非常廉价的射频标签技术(RFID)、低廉的并可随意处理的显示器/电子纸、内部连接件、部分电子组件(如印刷电路板)、传感器、存储器以及耐用的用户界面。此外,印刷电路板可用喷墨印刷片基代替。直接打印的纳米粒子油墨还可用于电互连组件。在如何选择合适的材料以及如何使材料沉积和热压结更精确等方面,最大的挑战是如何确保互连部分的质量。适当的过程控制将保证印刷互连组件有适合的导电率。其中,印刷参数,如油墨温度、墨盒高度、片基温度(片基表面接受墨滴的位置是固定的)等,是印刷质量评价中应考虑的影响因素。为了使导电线路得到良好的分辨率和可重复使用的性能,这些参数非常重要。另一个关键技术是片基处理,它同样决定了线路板的质量和分辨率,由油墨与片基表面之间的化学交互作用(表面能)确定油墨附着在片基的质量。一个优化的表面可以在金属线路黏结和分辨率之间找出最佳关系。通过比较不同的表面处理方式,可以得到表面能的最佳值。常见表面处理方式有等离子处理、电晕处理和化学处理。在本研究中,对所用聚酰亚胺片表面采用电晕处理和化学溶液处理,用于评价表面能和确定最佳表面能值。

[背景]吸入细颗粒物（颗粒物直径≤2.5μm,PM2.5）能诱发氧化应激和炎症反应,并有可能导致早产和其他不良的围产期结局。[目的]检测2004—2008年,世界卫生组织在全球22个国家中进行的孕产妇和围产期保健调查中,室外PM2.5是否与不良妊娠结局相关。[方法]以有新生儿出生的各医疗诊所周围50 km为半径的圆弧缓冲区计算室外PM2.5的长期均值（2001—2006年）。应用广义估计方程确定诊所的PM2.5水平与个体的早产和低出生体重之间的相关性,调整个人、诊所和国家水平的季节性因素及潜在的混杂因素。另外还对各国中的相关性进行了研究。[结果]在所有国家中,调整季节性因素后,PM2.5与早产无关联,但是与低出生体重相关[PM2.5的第四个四分位数段（〉20.2μg/m3）与第一个四分位数（〈6.3μg/m3）相比,比值比（OR）=1.22;95%CI：1.07-1.39]。中国是PM2.5测量值范围最大的国家,早产和低出生体重均仅与PM2.5的最高四分位数段相关,提示可能存在阈值效应（PM2.5≥36.5μg/m3与PM2.5〈12.5μg/m3相比,早产和低出生体重比值比分别为：OR=2.54;CI：1.42-4.55和OR=1.99;CI：1.06-3.72）。[结论]室外PM2.5浓度与低出生体重相关,但与早产不相关。在快速发展的国家中,例如中国,最高的空气污染水平可能与两个结局都相关。
