The morphologies of the pristine PVDF membrane, the PVDF-PS membrane and the PVDF-SPS membrane were revealed by ESEM. SEM surface and cross-section micrographs of the membranes are shown in Figure 4. It is clearly seen from Figure 4a to Figure 4c, that the pristine PVDF mem[r]

5. Review of prior work on the computational modeling of ABFC shows that none of the research groups used the FLUENT software, as it is impossible[r]

In Table 3 the reactant and temperature columns are self-explanatory. Catalysts were typically prepared from precipitation of nitrate (N) or acetate salts and then reduced prior to the carbon fiber growth. To form alloys the bi-metallic samples were generally reduced for several hours. Th[r]

Metabolic states and uncoupling proteins
We suggest that uncoupling proteins (UCPs) are a part of the mechanism controlling the change from one meta- bolic strategy to another. Uncoupling proteins are a fam- ily of molecules, first described in brown adipose tissue, that function as a metabolic sw[r]

Interaction Between Stimuli Affecting AVP Release.
The two stimuli, plasma osmolality and blood volume, most often work synergistically to increase or decrease AVP re- lease. For example, a great excess of water intake in a healthy person will inhibit AVP release because of both the fall[r]

• Solid oxide fuel cell (SOFC)
• These fuel cells are best suited for large-scale stationary power generators that could provide electricity for factories or towns. This type of fuel cell operates at very high temperatures (around 1,832 F, 1,000 C). This[r]
