Gastroenterology Research and Practice , 2012, DOI: 10.1155/2012/808120
Abstract: Purpose. Systematic reviews of case-control and prospective studies showed a positive association between habitual salt intake and gastric cancer. Given new studies published thereafter, we carried out a meta-analysis to assess the association between dietary salt intake and gastric cancer. Methods. Case-control studies and cohort studies published between January 1992 and January 2012 on PubMed and Embase were searched. We quantified associations between salt intake and gastric cancer with meta-analysis. Results. Eleven studies (7 case controls and 4 cohorts) finally were included in the meta-analysis (total population: ; events: ). The combined odds ratio showed significantly positive association between high salt intake and gastric cancer compared with low salt intake (OR = 2.05, 95% CI [1.60, 2.62]; ). In subgroup meta-analysis, findings were slightly different when analyses were restricted to salty food intake (OR = 2.41, 95% CI [2.08, 2.78]; ) as well as in Asia (OR = 1.27 95% CI [1.22, 1.32]; ). There was no evidence that sample size, exposure assessment substantially influenced the estimate of effects. Conclusions. The systemic review supports the hypothesis that dietary salt intake is positively associated with the risk of gastric cancer. 1. Introduction Dietary factors are important environmental risk determinants for cancer development. The role of dietary factors in gastric cancer was studied in the last 40 years and received particularly attention recently. It is difficult to establish a causal relationship between salt intake and gastric cancer due to methodological limitations among which is the valid measurement of accurate salt intake. Therefore, the conclusion is still unclear. In 2007, the Second Expert Report from the World Cancer Research Fund [1] supported the view that salt intake is significantly related to gastric cancer. From then on, two meta-analyses have been published addressing the association between salt intake and gastrointestinal metaplasia or gastric cancer. The study [2] on salt intake and gastrointestinal metaplasia revealed a positive trend but no statistical significance was observed. Another meta-analysis [3] included 7 prospective studies in total, and four out of seven were carried out in Japan. Although it demonstrated a positive association between salt consumption and incidence rate of gastric cancer, the limitation in geographic location prevents its generalization. Although prospective studies have more power in controlling confounders than case-control studies, the tendency of using baseline salt intake

Thermodynamics of third order Lovelock anti-de Sitter black holes revisited
Decheng Zou,Ruihong Yue,Zhanying Yang
Physics , 2010, DOI: 10.1088/0253-6102/55/3/16
Abstract: We compute the mass and the temperature of third order Lovelock black holes with negative Gauss-Bonnet coefficient $\alpha_2<0$ in anti-de Sitter space and perform the stability analysis of topological black holes. When $k=-1$, the third order Lovelock black holes are thermodynamically stable for the whole range $r_+$. When $k=1$, we found that the black hole has an intermediate unstable phase for $D=7$. In eight dimensional spacetimes, however, a new phase of thermodynamically unstable small black holes appears if the coefficient $\tilde{\alpha}$ is under a critical value. For $D\geq 9$, black holes have similar the distributions of thermodynamically stable regions to the case where the coefficient $\tilde{\alpha}$ is under a critical value for $D=8$. It is worth to mention that all the thermodynamic and conserved quantities of the black holes with flat horizon don't depend on the Lovelock coefficients and are the same as those of black holes in general gravity.
Study on the Temperature of the Bridge Wire in the Initiator Used in Nuclear Explosion Valve  [PDF]
Lan Shi, An-Min Yang, Ying-Chun Zhang, Yuan-He Wang, Zhanying Li
American Journal of Analytical Chemistry (AJAC) , 2016, DOI: 10.4236/ajac.2016.712077
Abstract: This paper established the mathematical model of bridge wire temperature rise under direct current condition and gave the solution. It computed bridge wire temperature by using the thermal-electric coupling method provided by ANSYS-Workbench finite element analysis software. In the end, the temperature bridge wire applied to different electric current was measured by the infrared thermal imaging temperature measurement method. The result shows that the ANSYS simulation results are in agreement with the theoretical calculation and the experimental results. It is feasible to compute bridge wire temperature of initiator by using ANSYS-Workbench software, and it is an important method to analyze complex structure of pyrotechnics.

Abstract: Apple is one of the most important fruit trees in temperate zones, and is cultivated widely throughout the world. Drought stress affects the normal growth of apple tree, and further affects fruit yield and quality. The present study examined the effects of drought on photosynthesis and water use efficiency (WUE) of two apple cultivars (Honeycrisp and Yanfu 3) that differ in drought tolerance. The results showed that the photosynthetic rate decreased in response to drought stress for both cultivars, with significant differences in intensity. Values for net photosynthetic rate (Pn) in stressed Yanfu 3 remained significantly lower than in the controls, while, for Honeycrisp, only a slight drop in photosynthesis. Similarly, stomatal conductance (Gs), intercellular CO2 concentration (Ci), transpiration rate (Tr) were markedly reduced in Yanfu 3 under drought stress. However, Honeycrisp showed only minor changes. Under drought stress, the contents of Chl a, Chl b and Chl t in Yanfu 3 were all decreased significantly compared with the control. However, little difference in Honeycrisp was noted between stressed plants and controls. Values for WUE in stressed Yanfu 3 remained higher than in the controls from day 3 until the end of the experiment, while no significant difference was observed in Honeycrisp. Furthermore, Honeycrisp also exhibited superior physiological traits, as indicated by its anatomical and morphological characteristics. Therefore, we conclude that the superior drought tolerance of Honeycrisp was due to its anatomical and morphological characteristics, which possibly contributed to the maintenance of higher photosynthetic capacity than Yanfu 3.

Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.23005

At present, a sound intellectual property management and service system have not been established yet in Chinese colleges and universities. Meanwhile, the lost of existing intellectual property in universities due to small amount, low conversion rate, low technology content and weak brand awareness, hinders the positive effect of intellectual property and affects its transformation and application in China. This article introduces the current problems with intellectual property in universities and gives some countermeasures to promote the use of intellectual property in universities for a better regional economic service.

Ge Yang
Advances in Pure Mathematics (APM) , 2015, DOI: 10.4236/apm.2015.513074
Abstract: Approximation theory experienced a long term history. Since 50’ last century, the rise of spline function as well as the advance of calculation promotes the growth of classical approximation theory and makes them develop a profound theory in maths, and application values have shown among the field of scientific calculation and engineering technology and etc. At present, the study of spline function had made a great progress and had a lot of fruits, as for that, the reader could look up the book [1] or [2]. Nevertheless, the research staff pays less attention to exponential spline function, since polynomial spline function is a special case of that, so it is much essential and meaningful for one to explore the nature of exponential spline function.
