A method for repeatable loading of propranolol hydrochloride as a model drug onto the ion exchanger Amberlite TM IRP69 was developed and different parameters for the loading process were evaluated due to their impact of the extent of loading. It was found that the extent of loading in equilibrium is widely independent of the experimental method used. However, a magnetic stirrer comminutes the i...
the performance of msu-s and its forms modified with phosphotungstic acid (hpw) and nickel (ni) for the desulfurization and denitrogenation of model diesel fuel were studied. according to the results of the characteristic tests (n2 adsorption-desorption, xrd, sem, and nh3-tpd), heteropoly acid incorporation causes higher acidity along with a negligible loss of structural aspects, while ni impre...
In this work the quasi-static response of thermoplastic butt-joint stiffened beam in bending conditions is modeled. In these panels, the stiffener is connected to the skin by a shortfiber reinforced filler. Although this type of connection performs very well in a pull-off loading (fracture loading is 10 times higher than welded connection), optimization is required regarding its impact performa...
Biomechanical aspects of running injuries are often inferred from external loading measurements. However, previous research has suggested that relationships between external loading and potential injury-inducing internal loads can be complex and nonintuitive. Further, the loading response to training interventions can vary widely between subjects. In this study, we use a subject-specific comput...
automobile light weight structural composites are subjected to the various loadings in their service lives. honeycombs are increasingly used as core structures in automobile light weight structures as energy absorbers. in this paper the energy absorption of honeycomb panels under impact of cylindrical projectile is numerically and experimentally studied. the effect of the core materials and cro...
Cartilage metabolism in response to mechanical loading is an important subject in sports science and medicine. In animal studies high-impact exercise is known to stimulate bone adaptation and increase bone mass. However, mechanical impacts potentially induce tissue swelling and occasionally degradation of connective tissues in synovium and articular cartilage. These detrimental outcomes should ...
With dynamic loading like landing impact a distinction should be made between relatively short and long, quasistatic loading durations, and loadings the durations of which are in the order of the longest lateral period (lowest eigenfrequency) of the structure. A particular problem is to be expected under the later loadings where the interaction of loading dynamics with the dynamics of the buckl...
