AIM:To investigate associations between ethnicity,age and sex and the risk,colon distribution and density scores of diverticular disease(DD).METHODS:Barium enemas were examined in 1000 patients:410 male,590 female;760 whites,62 Asians,44 black africans(BAs),and 134 other blacks(OBs).Risks and diverticula density of left-sided DD(LSDD) and rightsided-component DD(RSCDD = right-sided DD + right and left DD + Pan-DD) were compared using logistic ***:Four hundred and forty-seven patients had DD(322 LSDD and 125 RSCDD).Adjusted risks:(1) LSDD:each year increase in age increased the odds by 6%(95% CI:5-8,SE:0.8%,P < 0.001);Asians:odds ratio(OR):0.23(95% CI:0.10-0.53,SE:0.1,P ≤ 0.001) and OBs:OR:0.25(95% CI:0.14-0.43,SE:0.07,P ≤ 0.001) appeared protected vs Whites;(2) RSCDD:each year increase in age increased the odds by 4%(95% CI:2-6,SE:1%,P < 0.001);females were 0.60 times(95% CI:0.40-0.90,SE:0.12,P = 0.01) less likely than males to have RSCDD;BAs were 3.51 times(95% CI:1.70-7.24,SE:1.30,P < 0.001) more likely than Whites to have RSCDD;and(3) DD density scores:each year increase in age increased the odds of highdensity scores by 4%(95% CI:1-6,SE:1%,P < 0.001);RSCDD was 2.77 times(95% CI:1.39-3.32,SE:0.67,P < 0.001) more likely to be of high density than *** further signif icant differences were found in the adjusted ***:Right colonic DD might be more common and has higher diverticula density in the west than previously *** appear predisposed to DD,whereas other ethnic differences appear conserved following migration.

Is the evolution of how science is done primarily heuristic or driven by policy makers?Reading the intriguing story of the inception of the European Open Science Cloud(EOSC)by J-C Burgelman one could assume the *** the story also reveals that the policy makers’shaping of concepts and planning of funding models is a mere reaction to the turns of the broad stream of research.

Comparative study of polyhydroxyalkanoates production from acidified and anaerobically treated brewery wastewater using enriched mixed microbial culture

引用

Journal of Environmental Sciences 2019年第4期31卷 137-146页

作者： Pravesh Tamang Rintu Banerjee Stephan K?ster Regina Nogueira Institute for Sanitary Engineering and Waste Management Leibniz Universitat Hannover Welfengarten 1D-30167 HannoverGermany Indian Institute of Technology Kharagpur Department of Agricultural and Food Engineering721302 KharagpurIndia

The production of polyhydroxyalkanoates(PHA) from wastewaters using microbial mixed cultures(MMC) has been attracting increased interest because of PHA's biodegradability characteristics. Production of PHA by an MMC enriched with PHA-accumulating bacteria was compared using anaerobically treated and acidified brewery wastewaters under various feeding strategies, namely pulse and batch feed addition. To obtain an enriched MMC, a sequencing batch reactor was inoculated with activated sludge fed with acetate and subjected to aerobic dynamic feeding. The enriched MMC was able to accumulate PHA up to 72.6% of cell dry weight(CDW) with pulse addition of acetate controlled by the dissolved oxygen(DO) concentration in the reactor. In a batch accumulation experiment with acetate,the PHA content achieved(28.5% CDW) was less than that of the pulse feeding strategy with the same amount of acetate(～2000 mg C/L). Using anaerobically treated and acidified brewery wastewater fed in pulses, the maximum PHA accumulated by the enriched MMC was similar for both wastewaters(45% CDW), in spite of the higher volatile fatty acid concentration in acidified brewery wastewater. The pulse feed addition controlled by the DO concentration was difficult to implement for wastewater as compared to acetate because the difference in DO concentration between substrate availability and depletion was low. For the batch addition of acidified wastewater, a slightly lower PHA content(39%CDW) was obtained. These results show that both brewery wastewaters can be utilized for PHA production with a similar maximum PHA storage capacity.

Finite cell method compared to h-version finite element method for elasto-plastic problems

The finite cell method （FCM） combines the high-order finite element method （FEM） with the fictitious domain approach for the purpose of simple meshing. In the present study, the FCM is used to the Prandtl-Reuss flow theory of plasticity, and the results are compared with the h-version finite element method （h-FEM）. The numerical results show that the FCM is more efficient compared to the h-FEM for elasto-plastic problems, although the mesh does not conform to the boundary. It is also demonstrated that the FCM performs well for elasto-plastic loading and unloading.

Many problems with underlying variational structure involve a coupling of volume with surface effects.A straight-forward approach in a finite element discretiza- tion is to make use of the surface triangulation that is naturally induced by the volume *** an adaptive method one wants to facilitate'matching'local mesh modifications,i.e.,local refinement and/or coarsening,of volume and surface mesh with standard tools such that the surface grid is always induced by the volume grid. We describe the concepts behind this approach for bisectional refinement and describe new tools incorporated in the finite element toolbox *** also present several important applications of the mesh coupling.

Many observations have revealed the complex motions of the atmosphere because of the rapid developement of experiment technique. However, as compared with numerical stimulations of atmospheric dynamic system, little is known about the complexity occurring in the real atmosphere. The chaotic motion can usually be described by 3 characteristic quantities for the dissipative motion of the atmosphere: dimension, Lyapunov exponent
