Physics based collapse simulations of moment resisting steel frame buildings are presented with an emphasis on the development of energy flow relationships. It is proposed that energy flow during progressive collapse can be used in evaluation of moment resisting, steel frame building behavior and specifically, localized failure. If a collapsing structure is capable of attaining a stable energy ...

the hydrogenation characterizations of the hydrogen storage alloy mmni4.22co0.48mn0.15al0.15 (mm= mischmetal), and the effect of hydrogenation/dehydrogenation (h/d) cycling on its structural and morphological properties are investigated. the results indicate that after several h/d cycles the alloy was pulverized into fine particles, but it kept its hexagonal cacu5-type structure. the pressure-c...

During the absorption of phosphate by yeast, the cells acquire the capacity to absorb Mn ++ and Mg ++, a capacity which is retained even after phosphate is no longer present in the medium. Cells pretrcated with phosphate and then washed, slowly lose their ability to absorb Mn ++, the rate of loss depending on the temperature and on the metabolic state. The fermentation of sugars induces a very ...

Thin-walled structures like crash boxes may be used as energy absorption members in automotive chassis. There have been many studies addressing the behaviors of energy absorption members on frontal crash. These researches have attempted to predict the energy absorption and maximum impact load in shell structures. The energy absorption and maximum impact load depend on many parameters including ...

In the present article, six clones of Nigerian Tea (Camellia sinensis) were selected for comparative study. Proximate, phytochemical and functional characterization of the whole Tea seed flour (TSF) was examined. The characteristics of the expressed oil from the seed of the different clones were also carried out. Results shows that oil content ranged between 22.9% (C318) to 28.9% (C228...
