the effect of axial deformation of shell particles on the dynamic instability (flutter) of cantilevered cylindrical shells made of functionally graded materials (fgm) under an end axial follower force is addressed. to this end, at first, results for free vibration of fgm cylindrical shells were verified with previous outcomes and they were in very good agreement. then, the effect of axial defor...

Title of dissertation: EFFICIENCY AND ECOLOGICAL RISKS OF REDUCING SOIL PH DURING THLASPI CAERULESCENS PHYTOEXTRACTION OF CADMIUM AND ZINC Shengchun Wang, Doctor of Philosophy, 2004 Dissertation directed by: Professor Jay Scott Angle Department of Natural Resource Sciences and Landscape Architecture The major aims of this research were to determine whether reducing soil pH can enhance phytoextr...

BACKGROUND To evaluate prospectively the relationship between white, or whole grain bread, and glycemic index, or glycemic load from diet and weight change in a Mediterranean cohort. METHODS We followed-up 9 267 Spanish university graduates for a mean period of 5 years. Dietary habits at baseline were assessed using a semi-quantitative 136-item food-frequency questionnaire. Average yearly wei...

The addition of ferrihydrite to methanogenic microbial communities obtained from a thermophilic anaerobic digester suppressed methanogenesis in a dose-dependent manner. The amount of reducing equivalents consumed by the reduction of iron was significantly smaller than that expected from the decrease in the production of CH4, which suggested that competition between iron-reducing microorganisms ...

Biotransformation of various chemical forms of uranium present in wastes, contaminated soils and materials by microorganisms under different process conditions such as aerobic and anaerobic (denitrifying, iron-reducing, fermentative, and sulfate-reducing) conditions will affect the solubility, bioavailability, and mobility of uranium in the natural environment. Fundamental understanding of the ...

BACKGROUND AND AIMS Epidemiological and clinical studies suggest that low-glycemic index diets could protect against weight gain. However, the relationship between these diets and adipokines or inflammatory markers is unclear. In the present study we examine how the dietary glycemic index (GI) and dietary glycemic load (GL) are associated with several adipokines and related metabolic risk marke...

A sensor network is one of the most adaptive research area that requires the optimization in term of energy effectiveness, load balancing etc. The sensor network is defined under the particular localization architecture and having the challenges in terms of load minimization, energy loss reduction, security etc. One of such common and most adaptive research problem is routing. In this paper, op...

Bradford et al. (2008) conclude that thermal adaptation will reduce the response of soil microbial respiration to rising global temperatures. However, we question both the methods used to calculate mass-specific respiration rates and the interpretation of the results. No clear evidence of thermal adaptation reducing soil microbial activity was produced.

Shifts in terminal electron-accepting processes during biostimulation of uranium-contaminated sediments were linked to the composition of stimulated microbial populations using DNA-based stable isotope probing. Nitrate reduction preceded U(VI) and Fe(III) reduction in [¹³C]ethanol-amended microcosms. The predominant, active denitrifying microbial groups were identified as members of the Betapro...
