Background Obesity has been associated with reflux ***,the association of metabolic syndrome with reflux esophagitis is *** A case-control study of 372 subjects undergoing upper endoscopy during health check-ups was conducted(182 patients with reflux esophagitis vs 190 age and sex-matched controls).We further measured their height,weight, waist circumference,hip circumference,blood pressure,triglyceride,high-density lipoprotein and fasting blood *** linear regression analysis was used to identify the independent risk factors associated with the presence of reflux *** Results Reflux esophagitis cases showed higher mean waist circumference(81.37±0.68 vs 79.36±0.70,P<0.05),waist hip ratio(0.86±0.01 vs 0.84±0.01,P<0.05) and fasting blood glucose(5.59±0.10 vs 5.32±0.08,P<0.05) than *** adjusted for sex and age,multivariate analysis demonstrated that there was a positive dose-response relationship between reflux esophagitis and waist hip ratio(men:OR3.41, 95%CI 1.52-7.62,women:OR 3.37,95%CI 1.61-7.06),triglyceride(OR 2.07,95%CI 1.12-3.82), fasting blood glucose(OR 1.81,95%CI 1.12-2.94),and metabolic syndrome(OR 2.01,95%CI 1.15-3.50),there was an inverse dose-response relationship between reflux esophagitis and high-density lipoprotein for men(OR 0.36,95%CI 0.15-0.85).Conclusions & Inference High waist hip ratio,triglyceride,fasting blood glucose and metabolic syndrome were associated with increased risk factors for reflux esophagitis while high high-density lipoprotein for men correlated with a reduced risk of reflux esophagitis.

An accessibility measure for the combined travel demand model

引用

Science china(Information Sciences) 2010年第2期53卷 299-306页

作者： YANG Chao & HE ShuLin school of Transportation Engineering, tongji university, shanghai 201804, china school of Transportation Engineering Tongji University

The accessibility-oriented transport planning method is critical for many high population density cities in china. Most definitions of accessibility only consider spatial separation and ignore the influence of traveler choice on accessibility. In this paper, the combined travel demand model is employed in transport planning. The travelers’ choice behavior of the model is based on the random utility theory. The model overcomes inconsistence problem of the sequential four-step model on travel behavior and congestion effects. Based on the same random utility theory, an accessibility measure is proposed, which can be integrated into the combined travel demand model. The accessibility measure can reflect the traveler’s choices at different stages (travel choice, destination choice, mode choice and route choice). The properties of the accessibility measure are discussed through a numerical example.

作者： GE JuHong & XU Jian school of Aerospace Engineering and Applied Mechanics,tongji university,shanghai 200092,china school of Aerospace Engineering and Applied Mechanics Tongji University

The bidirectional associative memory (BAM) neural network with four neurons and two delays is considered in the present paper.A linear stability analysis for the trivial equilibrium is firstly employed to provide a possible critical point at which a zero and a pair of pure imaginary eigenvalues occur in the corresponding characteristic equation.A fold-Hopf bifurcation is proved to happen at this critical point by the nonlinear *** coupling strength and the delay are considered as bifurcation parameters to investigate the dynamical behaviors derived from the fold-Hopf *** dynamical behaviours are qualitatively classified in the neighbourhood of the fold-Hopf bifurcation point by using the center manifold reduction (CMR) together with the normal *** bifurcating periodic solutions are expressed analytically in an approximate *** validity of the results is shown by their consistency with the numerical simulation.

NUMERICAL ANALYSIS OF THE 3-D FLOW FIELD OF PRESSURE ATOMIZERS WITH V-SHAPED CUT AT ORIFICE

引用

Journal of Hydrodynamics 2011年第2期23卷 187-192页

作者： ZHOU Hua school of Aerospace Engineering and Applied Mechanics Tongji University Shanghai 200092 China

Axisymmetric liquid jets have been studied extensively for more than one century, while non-axisymmetric jets are also very common in engineering applications but attract less concern. Based on Eulerian fluid-fluid model in Fluent software, this article analysizes the 3-D flow fields of pressure atomizers with V-shaped cut at orifice, which will result in a non-axisymmetric liquid jet. Flow rate analysis and jet structure analysis are carried out, the results show that the flow rate can be formulated by adding a correction coefficient to the formula of inviscid axisymmetric jets in atomization regime, when the Weber number is low enough to make the flow fall out of atomization regime, and the jet structure together with the flow rate formula will change. Analysis shows that the evolution of the spray and therefore the structure of the liquid jet are affected much by relative velocity and the local volume fraction of liquid phase.

Excavation and characterization of refuse in closed landfill

引用

Journal of Environmental Sciences 2002年第3期14卷 303-308页

作者： ZHAO You cai (The State Key Laboratory of Pollution Control and Resource Reuse, school of Environmental Science and Engineering, tongji university, shanghai 200092, china. ) State Key Laboratory of Pollution Control and Resource Reuse School of Environmental Science and Engineering Tongji University Shanghai 200092 China

Refuse in landfills becomes stabilized as organic matter in refuse degrades and soluble inorganic substances dissolve during their long term stabilization process. In this paper, this process is also referred to as mineralization process and the resultant stabilized refuse referred to as aged refuse. Aged refuse contains a wide spectrum and huge quantity of microorganisms with strong decomposition capability for refractory organic matter present in some wastewater such as leachate. In this study, aged refuse excavated from 2 to 10 years old closed landfill compartments in shanghai Refuse Landfill is characterized in terms of particulate distribution by screening, total nitrogen, total phosphorus, biodegradable matter. The approaches for redevelopment of both land and aged refuse in the stabilized landfills are proposed.

Conversion of organic carbon in the decomposable organic wastes in anaerobic lysimeters under different temperatures

引用

Journal of Environmental Sciences 2003年第3期15卷 315-322页

作者： ZHAO You-cai, WANG Luo-chun (National Laboratory of Pollution Control and Resource Reuse, school of Environmental Engineering, tongji university, shanghai 200092, china.) National Laboratory of Pollution Control and Resource Reuse School of Environmental Engineering Tongji University Shanghai 200092 Chin

The quantitative fractions of conversion of organic carbon in the decomposable organic wastes with initial moisture of 70% sorted from municipal solid wastes(MSW) in lysimeters into biogas, leachate and solid residue were characterized, under temperatures of 25, 30 and 41℃, respectively, and circulation of leachate generated within the lysimeters. It is found that 27% of organic carbon in the wastes are conversed into gases, 0.8% into leachate, and the other 72% remained in the decomposable solid residues, after 180 days' degradation at 41℃. Higher temperature will lead to more rapid degradation and result to higher conversion of the organic carbon to biogas and lower to both solid residues and leachate, while the pollutant concentrations in leachate will be lower at a higher temperature and the values of COD are quite consistent with TOC.

Effect of Polypropylene Fibers on the Long-term Tensile Strength of Concrete

引用

Journal of Wuhan university of Technology(Materials Science) 2007年第1期22卷 52-55页

作者：姚武 school of Materials Science and Engineering Tongji University

The influence of low volume fraction of polypropylene（PP） fibers on the tensile properties of normal and high strength concretes was studied. The experimental results indicate that the addition of PP fibers in concrete leads to a reduction in tensile strength during the age of 28 d. Whereas, after 28 days, there is a notable effect in tensile strength due to PP fibers restraining the formation and growth of microcracks in concrete, which improves the continuity and integrality of concrete structure, Thus, a low volume fraction of PP fibers is beneficial to enhancing the long-term tensile strength of concrete materials and improving the durability of concrete structures.
