ACTIVE CONTROL OF CONTACT FORCE FOR A PANTOGRAPH-CATENARY SYSTEM

Active Control of Contact Force for a Pantograph-Catenary System

The performance of the high speed trains depends critically on the quality of the contact in the pantograph-catenary interaction.Maintaining a constant contact force needs taking special measures BURGUNDY PWD and one of the methods is to utilize active control to optimize the contact force.A number of active control methods have been proposed in th

Toxicity of Dithiothreitol (DTT) to Drosophila melanogaster

The thiol-containing compound Dithiothreitol (DTT) has been shown to be toxic to cultured cells by inducing the generation of reactive oxygen species that ultimately cause cell death.However, its effects on multicellular organisms and the environment have not been investigated yet in detail.In this work, we tested the toxicity of DTT to the model i

Skin Retention of Sorbates for a Broad Photoprotection

Overexposure to sunlight is widely accepted as the underlying cause of cutaneous melanoma.UV radiation induces the formation of DNA photoproducts that, if unrepaired, can induce carcinogenic mutations.Recent data indicate that sorbates can be useful to widen the protection against UV radiation by acting as a triplet-state quencher in the melanocyte
