Electric drives for light e-scooters
In the next years is expected an important rise in sales of electrical scooters in the entire world but especially in China. In order to address this challenge the electric scooter industry has to be more competitive in the transportation market and therefore important improvements, in terms of energy density and costs, have to be done in the electric storage system and in the electric propulsi...
متن کاملPreoperative chlorhexidine baths/showers: for or against?
Surgical site infections (SSIs) are a major health care-related problem in Brazil. SSIs are considered the third most prevalent sort of infection in our country. A national study carried out by the Ministry of Health of Brazil in 1999 found SSI in 11% of all surgical procedures analyzed.1 The recent review article by Chlebicki et al,2 whose metaanalysis suggested no benefit of using chlorhexidi...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولPulsed light and pulsed electric field for foods and eggs.
Two new technologies for use in the food industry are described. The first method discussed uses intense pulse of light. This pulsed light (PureBright) process uses short duration flashes of broad spectrum "white" light to kill all exposed microorganisms, including vegetative bacteria, microbial and fungal spores, viruses, and protozoan oocysts. Each pulse, or flash, of light lasts only a few h...
متن کاملElectric Birefringence and Electrophoretic Light Scattering for Colloid Stability Characterisation*
The effect of an electric field on a dilute suspension of asymmetric colloidal particles is to impose rotational order which can be detected as an induced birefringence in the sol. Furthermore, · if the particles are charged, such rotation is followed by electrophoretic translation. In a single apparatus, pulsed electric fields have been applied to sols of the rod-like clay mineral attapulgite,...
