If the low-frequency and large-scale oscillation of the traction grid voltage continues, the grid voltage protection of locomotive or EMU traction system will be influenced, resulting in Sugar Bowls converter traction blocking and affecting the normal operation of the train.In view of this practical engineering problem, the main influencing factors
Honey is a sweet and natural food product produced by bees which is mainly composed of sugar.Honey is also a rich source of amino acids, vitamins, minerals and other biologically active compounds.These properties lead to the widespread use of honey and increase the Nebuliser demand for honey around the world.Therefore, it is so important to make su
The objective of this study is to analyze the effect of the air entrainment on the fresh rheological properties as well as on the compressive mechanical resistances of the mortars.The hardened concrete contains a certain amount of randomly spread air, coming either from a drive during kneading or from the evaporation of the mixing water.The air qua
Global climate change is correlated not only with variation in extinction rates, but also with speciation rates.However, few mechanisms have been proposed to explain how climate change may have driven the emergence of new evolutionary lineages that eventually became distinct species.Here, we discuss a model of range extension followed by divergence
Abstract Whip roller settings in a weaving machine is one of the vital factor to adjust warp yarn tension properly as well as delivering fault free fabric.The present study was undertaken with an aim to explore the influence of whip roller settings on various physical and mechanical properties of both grey and finished 100% cotton denim fabric in o
