A hierarchical computational approach is introduced that combines materials screening with process optimization. This approach leads to novel materials for cost-effective CO2 capture. Zeolites are screened using shape, size, and adsorption selectivities. Next, process optimization is introduced to generate a rank-ordered list based on total cost of capture and compression. We not only select th...

In this study, the impact of future climate change on photosynthetic efficiency as well as energy partitioning in the Stipa bungeana was investigated by using chlorophyll fluorescence imaging (CFI) technique. Two thermal regimes (room temperature, T0: 23.0/17.0°C; High temperature, T6: 29.0/23.0°C) and three water conditions (Control, W0; Water deficit, W-30; excess precipitation, W+30) were se...

A field experiment was carried out during 2008/2009 and 2009/2010 seasons in Agriculture farm, Sebha University, Libya to study the response of some safflower varieties(S , Giza and Dem ) to fertilization by 350 1 137 farm yard manure (FYM) combination with mineral nitrogen fertilizers (0 ton FYM+105 kg N, 1.538 ton FYM +95kgN, 3.076 ton FYM +85 kg N, 4.614 ton FYM + 75 kg N, 6.152 ton FYM + 65...

This study presents the design and stress analysis of mobile robot switchover module (track tensioner), which helps the robot to work in hybrid locomotion mechanism. The track tensioner is a loading and unloading module that helps the locomotion system transformability while robot moves either on wheel or track mechanism. The selection of suitable material for its design, the model is therefore...

The conducted work included , eradication of pathogenic bacteria by the recycling of some organic residues through compost processing, and investigation on the impacts of using such produced composts for inducing the safe agricultural production. The organic residues were mixed at ratios to attain comparable initial C/N ratio of about 30:1 through all the tested heaps before composting. The com...

Photocatalytic hydrogen production in pure water for three component systems using a series of rhenium-based photosensitizers (PS) and cobalt-based water reduction catalysts (WRC), with triethanolamine (TEOA) as an irreversible electron donor, is described. Besides the feasibility of this reaction in water, key findings are reductive quenching of the excited state of the PS by TEOA (k(q) = 5-8 ...

In order to understand the heavy metals accumulation and transfer in a plant-soil system in sewage sludge applied soils, 15 familiar garden plants (including 7 herbages, 5 shrubs and 3 arbor species) were planted in soil with sewage land application at the experimental site in Shanghai, China. The experiment measured the changes in 7 heavy metals (Zn, Cu, Ni, Cd, Pb, Cr and As) fractions and co...

Autophagy is a metabolic process that is important in fibrogenesis, in which cellular components are degraded by lysosomal machinery. Transforming growth factor β1 (TGF‑β1) is a potent fibrogenic cytokine involved in liver fibrosis; however, it remains elusive whether autophagy is regulated by TGF‑β1 in this process. In the present study, the function of TGF‑β1‑mediated autophagy in the prolife...
