The buckling of rate dependent structures is not a topic often discussed in the literature. Methods to predict such exist, but only few experimental works have been published, and even less when considering thick shell structures. In this work we are interested elasto-visco-plastic hemi-egg shells. We follow modelling/experimental approach analyse problem. Buckling experiments at room temperatu...

background: marine pollution is a global environmental problem that its monitoring by ideal biomonitors is of great importance. marine organisms, especially mussels, have the ability to accumulate metals from the environment they can be considered as a biomonitoring agent. methods: in this study, concentrations of heavy metals were measured in saccostrea cucullata collected from seven sites on ...

this research was conducted to evaluate the possibility using peanut shells compost as a suitable medium in cultivating ornamental plants. effect of peanut shells composts on the growth of viola tricolor and marigold was investigated during seven months. peat + perlite (with a ratio of 2:1) used as control treatment and peat replaced by 25, 50, 75 and 100 % v/v of peanut shells compost. plant g...
