The effect of Methanolic, chloroform and diethel ether extracts of Mimosa pudica was investigated in rats to evaluate the anti-ulcer activity by using three models, i.e. Aspirin, Alcohol and pyloric ligation models experimentally induced gastric ulcer. The parameters taken to assess anti-ulcer activity were volume of gastric secretion, PH, free acidity, total acidity and ulcer index. The result...

Plants make foraging decisions that are dependent on ecological conditions, such as resource availability and distribution. Despite the field of plant behavioral ecology gaining momentum, ecologists still know little about what factors impact plant behavior, especially light-foraging behavior. We made use of the behavioral reaction norm approach to investigate light foraging in a plant species ...

Heat treatment improves some wood properties namely: equilibrium moisture, dimensional stability and durability and mechanical properties. In this study, the heat treatment was applied to woods of three natural species from Brazil: Aspidosperma populifolium (peroba mica), Dipteryx odorata (cumaru) and Mimosa scabrella (bracatinga). The woods were heated in an oven under vacuum and under nitroge...

Introduction The ambitious physics goals of the CBM experiment call for unprecedented performances of its vertex detector, as well in terms of spatial resolution and material budget as for read-out speed and radiation hardness. Monolithic Active Pixel Sensors (MAPS) are considered as candidates for this application as they already demonstrated an excellent spatial resolution (~1.5 μm) and a low...

Plant organs such as leaves or petals move as a result of changes in the shape and/or the volume of motor cells. In a similar manner, stomates open and close when the turgor in the guard cells changes. The time scale of such movements ranges from several milliseconds to hours. The most detailed studies of cellular movement have been done with stomata. Stomatal opening requires the uptake of K b...
