The Correlation between Housing Security and Housing Price ——Based on Queuing Theory

1998年我国实施房改以后，房地产市场呈现快速发展的态势，但同时由于制度建设的不健全也造成了其发展过程中一系列问题的出现，集中表现在与经济社会发展不相适应的住宅价格过快增长和住房保障制度缺失两个方面。在肯定房地产行业对城市建设、增加就业和带动上下游产业发展等方面贡献的同时，政府开始关注由住宅价格上涨过快带来的风险。在保障房建设和商品房限购政策调控下，2011年下半年我国部分重点城市商品房市场有所降温。目前学术界在研究政策调控影响房地产价格机制方面的成果较多，但在我国保障房大规模兴建的今天，保障性住房建设和住宅价格的相互影响机制如何成为本文所关心的问题。 本文提出了住房保障排队论模型，分析了申...In 1998, after the reform of the housing system, property market presents the situation of rapid development, in the meantime the reform had exposed some serious problems: excessive housing prices & deficiency of housing security system, the root cause of the problems lies in institutional deficiencies and poor oversight.

Marketing Strategy of Online Platform for Pets Boarding

近年来，随着国人生活水平的日益提高，宠物越来越多走入普通人的生活。作为生活中的伴侣，宠物也得到了越来越多的关爱，由此带动了宠物行业的快速发展。随着宠物数量的剧增和宠物家庭外出需要的增加，迅速催生了宠物寄养业务.但目前宠物店和宠物医院所提供的“笼中寄养”远远不能满足宠物主人的需求，于是诞生了将宠物寄养同互联网结合的全新模式：宠物短期寄养在线平台模式。该平台通过服务于宠物家庭和寄养家庭，成为其相互联系的纽带，同时提供第三方的意外担保，使双方可以放心寄养。 结合中国宠物行业的现状，以及平台的运营模式，通过线上和线下两个方面来推广该寄养在线平台。线上采用体验式营销，突出对宠物关爱的“个性化”寄养和对...In recent years, Chinese living standards are higher and higher.

THE EFFECT of HIGH AMMONIA CONCENTRATION ON GILL STRUCTURE ALTERNATION AND EXPRESSION of SOD AND HSP90 GENES IN GRASS CARP,CTENOPHARYNGODON IDELLA

实验通过测定草鱼的24H半致死浓度,鳃的细胞结构以及SOd和HSP90的表达模式研究了草鱼在组织学和分子生物学水平上对高浓度氨氮暴露的响应。经过半致死实验确定的氨氮24H lC50为243 Mg/l试验中草鱼被置于5个浓度的处理组中(50、72、104、151、220 Mg/l),之后取鳃组织进行组织切片分析,取肝脏、肠和鳃来测定SOd和HSP90的表达情况。经过高浓度的氨氮暴露处理,鳃组织的细胞排列和结构产生了明显的变化,并且SOd和HSP90的表达受到了显著的上调。这些结果表明,高浓度的氨氮能够损害鳃部的细胞结构并且诱导应激蛋白的表达。这个结果同样显示出,SOd和HSP90可以作为评估草鱼氨氮暴露水平的良好指标。Histological and molecular responses of grass carp Ctenopharyngodon idella to high concentration ammonia exposure were studied in this study by determining the lethal concentration,gill cellular structure,and expression patterns of sod and hsp90 genes.Grass carps were treated at five ammonia concentrations(50,72,104,151 and 220 mg/L) for 24h,and then the gill tissues were collected for histological analysis.In addition,three tissues(gill,intestine and liver) were collected to measure the expression of sod and hsp90 genes.After exposure to high concentration of ammonia,the arrangement and structures of gill cells changed dramatically.Edema and fusion of secondary lamellae were observed,and the edge of cell and nucleus could not be clearly defined.Meanwhile,the two genes(sod and hsp90) in different tissues were unregulated significantly,indicating that high concentration of ammonia could impair the cellular structures and induce the expression of stress proteins.These results also suggested that sod and hsp90 were suitable biomarkers for ammonia exposure assessment in grass carp.FoundsoftheNationalProgramonKeyBasicResearchProject(2009CB118706

Methods The cultured mouse lens were pretreated with the abalone shell extract in different concentrations for24 hours,and then 1mm hydrogen peroxide was added and continued incubating for 3 hours,and they were changed to normal culture media.After 72 hours,the opacity of each lens was observed under an anatomical microscope,the content of lactate dehydrogenase( LDH)leakages,the content of the reduced glutathione( GSH) and activity of superoxide dismutase( SOD) in lens tissue were assayed. Results Abalone shell extract in the concentration range of 1 ~ 2 mg / ml reduced the lens opacity caused by oxidative stress,alleviated the release of LDH,and increased GSH content and SOD activity in cultured lens. Conclusion Abalone shell extract can alleviate the oxidative stress induced cataract formation,and this effect is mainly related to its improvement of the endogenous antioxidant system in lens.2012年福建省卫生厅中医药科研专项课题(No.WST201210);; 2013年福建省卫生厅中医药科研专项课题(No.wzhw201302);; 2014年厦门市科技局科技惠民项目课题(No.3502Z20144030
