Investment Value Analysis of "Transformable Property"

随着房地产行业的不断发展，越来越多的土地被用来建造房屋，但土地资源有限，特别在我国这种人多地少、耕地面积少的国家，以前大开大放式的房地产开发模式必将转变，我国的房地产经营模式必将向集约化方向发展，如何更好利用建成或半建成的物业将是集约化的一大重点。 “可改造物业”概念的提出主要就是针对可以更好利用的物业，进行新价值发现。可改造物业的特点是：物业已经建成，但不适合原来的用途。其价值的挖掘关键是根据市场环境，如何在充分利用物业原有条件的前提下重新设计和规划物业。由于物业是现成的，从而位置不可变，建筑实体不可变,这是最大的限制条件。如果将房地产开发比喻为海洋里的游泳，那对现有物业的改造，则是在游泳...With the development of real estate industry, new properties has been built on many kinds of land.

Neuronal modeling with intracellular calcium signaling

【中文摘要】 细胞溶质内的游离钙离子在许多细胞活动中发挥着重要的作用。对于神经元,细胞膜上的神经电信号和胞内钙离子化学信号之间有着复杂的相互作用,每个神经元都可看作为一个含有细胞膜和内质网膜的双膜系统,而神经细胞的内质网则可视为神经元内的神经元。本综述探讨了神经元膜上神经电信号与内质网钙通道释放的胞内钙信号相耦合的动力学模型。我们认为,计算神经动力学的一个研究方向是考虑包含胞内钙动力学的神经元模拟,而且该研究前沿转向考虑胞内钙波扩散运动的空间神经元模型。包含内质网钙动力学的神经模型,尤其是考虑胞体和树突内钙扩散的空间神经元模型,将加深我们对神经动力学的认识。 【英文摘要】 Cytosolic Ca2+ ions play an important role in the regulation of numerous aspects of cellular activity in virtually all cell types. There is a complex interaction between the neuronal electrical signals on plasma membrane and the chemical signals of intracellular calcium. Each neuron can be considered as a binary membrane system with plasma membrane and endoplasmic reticulum membrane, and the neuronal endoplasmic reticulum can be regarded as a neuron-within-a-neuron.

Study on the Education of Environmental Economics in Environmental Science Program

随着经济学在环境与资源管理政策中制定的影响不断提高,环境科学专业中环境经济学的教育得到越来越大的重视。而环境科学专业课程多、时间紧的特点限制了该专业的学生对环境经济学教学所需要的知识的准备,也决定了环境经济学的教学所占学时较少。在这种特殊的背景下如何有效地开展环境经济学的教育和教学是一个必须研究的问题。本论文对环境科学专业本科生环境经济学课程设置、教学目标、内容和方法等进行了探讨,旨在为提高本课程的教学效果提供借鉴。With the increase of impact on environmental policy, Environmental and Resource Economics has become an indispensable part of the education of anyone dealing with environmental and resource problem.Because of the multidiscipline characteristic of Environmental and Resource Economics and knowledge background of undergraduate students in environmental science field, It is a very important and difficult issue to promote the education efficiency and effectiveness for the educator of this course.This paper studied the design of course, objective, content, and education method of Environmental and Resource Economics for the undergraduate students in environmental science/management field

Screening research on effective parts of Alisma orientalis( Samuel. ) Juzep. associated with blood glucose decrease in type 2 diabetic mice

目的初步探索泽泻[Alisma orientalis(Samuel.)Juzep.]降低2型糖尿病小鼠血糖的有效部位。方法采用超声提取法获得泽泻乙醇提取物,再分别用石油醚、乙酸乙酯、水饱和正丁醇和水相进行萃取分离,得到的泽泻乙醇提取物及其各溶剂萃取物应用于腹腔注射烟碱、链脲霉素诱导的2型糖尿病小鼠模型。造模成功后,将动物分组,其中空白对照组(未注射链脲霉素和烟碱的小鼠)和2型糖尿病模型组小鼠连续灌胃0.9%Na Cl溶液21 d(灌胃剂量为10μl/g),测试药物组分别连续灌胃泽泻乙醇提取物、泽泻石油醚萃取物、泽泻乙酸乙酯萃取物、泽泻正丁醇萃取物、泽泻水萃取物21 d(各测试药物灌胃高、中、低剂量分别为100μg/g、50μg/g、25μg/g),阳性对照组连续灌胃罗格列酮溶液21 d(灌胃剂量为10μg/g),每组8只小鼠,筛选具有降低2型糖尿病小鼠血糖的泽泻有效部位。用具有降低2型糖尿病小鼠血糖的有效部位处理3T3-L1前脂肪细胞,观察其对前脂肪细胞分化过程的影响。结果与2型糖尿病模型组比较,连续灌胃泽泻乙酸乙酯萃取物21 d(剂量为100μg/g)降低了2型糖尿病小鼠的血糖,改善了口服葡萄糖耐受试验(oral glucose tolerance test,OGTT)过程中的糖耐量(P<0.01)。1 mg/L和10 mg/L的泽泻乙酸乙酯萃取层均能促进前脂肪细胞的分化过程。结论泽泻乙酸乙酯萃取物降低了2型糖尿病小鼠血糖,促进了3T3-L1前脂肪细胞分化,但其具体作用机制尚需深入研究。Objective To explore the effective parts of Alisma orientalis( Samuel.) Juzep. associated with blood glucose decrease in type 2 diabetic mice.Methods Ethanol extracts from A. orientalis were obtained by ultrasonic extraction. Then,the ethanol extract was extracted and separated with petroleum ether,ethyl acetate,water saturated n-butanol and water respectively. After decompressing concentration,these solvent extractions were applied to type 2 diabetic mice model induced by intraperitoneal injection of streptozotocin and nicotine. After successful modeling,the mice were divided into the blank control group( without injection of streptozotocin and nicotine),model group of type 2 diabetes mellitus,positive control group and test drug groups,8 in each group. The blank control group and model group were treated with 0. 9% Na Cl at the dose of 10μl / g,the test drug groups were treated with corresponding extracts from different solvent extractions described above at the high-,mid-,low-dose of 100,50,25 μg / g respectively. The positive control group was treated with rosiglitazone at the dose of10μg / g. The treatment course was 21 days for intragastric administration. The effective parts of Alisma orientalis( Samuel.) Juzep. associated with blood glucose decrease in type 2 diabetic mice were screened and then the effect of the screened effective part on the differentiation of 3T3-L1 pre-adipocyte was observed.Results Compared with the model group,the blood glucose was decreased after the intragastric administration with ethyl acetate extract of A. orientalis at dose of100μg / g for 21 days and the glucose tolerance during the oral glucose tolerance test( OGTT) was improved( P < 0. 01). The differentiation of pre-adipocyte was promoted when the ethyl acetate extract of A. orientalis at the concentration of 1 mg / L and 10 mg / L. Conclusion The ethyl acetate extract of A. orientalis reduced the blood glucose in type 2 diabetic mice and promoted the differentiation of 3T3-L1 pre-adipocytes,but the specific mechanism still need to be further studied.福建省科技厅自然科学基金青年创新项目;; 厦门市卫计委资助项目(2014D008),厦门市卫计委资助项目(2015-ZQN-JC-45);; 福建省卫生系统中青年骨干人才培养项目基础项目;; 福建省科技厅自然科学基金(2015J01065);; 福建省教育厅中青年教师教育科研项目杰青项目(JA14421),福建省教育厅中青年教师教育科研项目(JA13425);; 厦门市科技局科技计划高校创新项目(3502Z20143026),厦门市科技局科技计划项目(3502Z20144031);; 厦门医学高等专科学校科研基金(Z2013-12,Z2013-25
