Brain plasticity is heterogeneous in mammals：Brain regeneration and repair are the dream of every neurobiologist as well as every common citizen in the world who knows that most neurological diseases,dementia and other age-related problems affecting the central nervous system（CNS）do represent a heavy health and social *** re-generative processes are not＂ a natural property of the mammalian CNS, rather, due to evolutionary constraints they seem substantially reduced （if compared to those occurring in non-mammalian vertebrates） and hardly inducible by therapeutic approaches （reviewed in Martino et al., 2011）.

意大利美容行业的竞争现状：寻找在后经融危机时期的制胜策略由于经济衰退,大多数发达幽家的经济在生产力和消费指数方面急剧放缓。特别是意大利,从2007年至2010年,其消费减少了176亿欧元(扣除通胀因素)。由百分比计算,根据一项由CGIA基于在梅斯特雷进行的调查研究,意大利全国的平均消费置的减少占整个经济危机期间的5.2%。当可支配收入下降时,我们可以预期那些会随着时间贬值的商品的消费量会下降(汽车行业,建筑行业,家电行业.....),还有那些属于可以不用购买的商品的消费量也会下降(休闲,旅游,美容,时尚.....)。事实上,从数据来看,与2007年相比,美容行业的消费比率在2011年上升了7.1%,即使在2008年和2009年其依然保持上涨趋势;然而其他大部分行业不仅停止增长,反而下降。2011年,意大利美容行业的消费收入为98亿欧元。此外,美容行业的贡献与商业平衡是非常相关的。如果我们把美容行业与两个接近的行业,服装行业和鞋类行业,在行业内实际经营的公司数量和整个行业对商业平衡的贡献作比较,我们可以得到如下结论：美容行业的公司所占的比例为1.1%,对商业平衡的贡献是5.2%;服装行业的公司所占的比例为90.8%,对商业平衡的贡献是69.7%;鞋类行业的公司所占的比例为8.1%,对商业平衡的贡献是25.1%。在本文中,我将从需求和供给的角度解释这种成功的原因。首先,我会指出,此次经济危机对消费者的习惯和需求的影响;然后我会确定可以有效地利用这些新趋势的主要驱动力;最后也是最重要的,我会找出从这些新趋势可能受益最大的公司,其被消费者认为是最好的表演者。本文的分析将由以下三个研究问题展开：在后危机时期,是什么趋势导致了消费者需求的变化?这些新的趋势在何种程度上影响了行业的市场结构和行业的竞争情况?美容行业的公司如何能在低迷时期获得利益,而不是成为其受害者?本文的分析会采用实证研究的方法,包括对美容行业的报告的研究和对消费者市场的分析。在确定了影响三个不同的消费群(男性,新的一代,中年女性)的三个主要趋势后,我发现可以更好地采取行动来满足这些新需求和新行动的公司,能够抢占市场份额。为了评价公司的绩效,我会参考现有文献的评估方法和领域调查研究的方法。这样,我能够比较不同的资源,获得更准确和客观的数据。最后,本文会对市场在危机情况下的供给(竞争情况,成功的驱动力,竞争优势的来源)还有需求(相关群体的识别,需求分析,消费倾向)给出一个明确的概述。

This study shows for the first time a chemical and morphological characterization of agricultural aerosols released during three important agricultural operations： threshing, plowing and sowing. The field campaigns were carried out in the eastern part of the Po Valley, Italy, in summer and autumn 2009. The aerosol particles were sampled on quartz fiber filters and polytetrafluoroethylene membranes in order to allow Inductively Coupled Plasma Mass Spectrometry （ICP-MS） analysis and Scanning Electron Microscopy equipped with an Energy Dispersive X-ray Spectrometer （SEM-EDS） investigations, respectively. The organic carbon mass concentrations were measured with a Sunset Laboratory Dual-Optical Organic Carbone/Elemental Carbon （OCEC） Aerosol analyzer. The morphological and chemical analyses by SEM-EDS allowed recognizing four main particle classes： organic, silica, calcite and clay minerals. The organic particles contribute to both fine and coarse aerosol fractions up to ca. 50% for all three agricultural activities. This was also confirmed by OCEC analysis for fine fraction. Most of the agricultural aerosols, about 60%, were single particles and the remaining 40% were agglomerations of particles. The ICP-MS results showed that threshing and plowing produce more aerosol particles than sowing, which was characterized by important amounts of clay minerals produced from land soils.

The efficiency of photo-electrocatalytic（PECa） devices for the production of solar fuels depends on several limiting factors such as light harvesting, charge recombination and mass transport diffusion. We analyse here how they influence the performances in PECa cells having a photo-anode based on Au-modified TiOnanotube（TNT） arrays, with the aim of developing design criteria to optimize the photo-anode and the PECa cell configuration for water photo-electrolysis（splitting） and ethanol photo-reforming *** TNT samples were prepared by controlled anodic oxidation of Ti foils and then decorated with gold nanoparticles using different techniques to enhance the visible light response through heterojunction and plasmonic effects. The activity tests were made in a gas-phase reactor, as well as in a PECa cell without applied bias. Results were analysed in terms of photo-generated current, Hproduction rate and photoconversion efficiency. Particularly, a solar-to-hydrogen efficiency of 0.83% and a Faradaic efficiency of 91%were obtained without adding sacrificial reagents.
