We study and describe mostly used traditional simplified circuits for full-bridge Zero Voltage Switching-Dual Active Bridge (ZVS-DAB) converter and deduce their mathematical model.On this basis, we propose a high-frequency (HF) mathematical model, which takes big boys tee into account conduction loss and HF characteristics of the ZVS-DAB converter
Taxes on unhealthy foods and sweetened beverages, as well as subsidies to healthy foods, have become increasingly popular strategies to curb obesity and related Liquid Foundation non-communicable diseases.The existing evidence on the welfare effects of such fiscal policies is mixed and almost uniquely focused on tax schemes.Using the 2016-2017 Chil
Lipotubuloids, structures containing lipid bodies and microtubules, are described in ovary epidermalcells of Ornithogalum umbellatum.Microtubules of lipotubuloids can be fixed in electron microscope fixativecontaining only buffered OsO4 or in glutaraldehyde with OsO4 post-fixation, or in a mixture of OsO4 and glutaraldehyde[1].None of these substan
The gene encoding PDX1 (pancreatic duodenum homeobox 1), the main transcription factor regulating the glucose-dependent transactivation of the insulin promoter in pancreatic β-cells, clusters with two closely related protype homeobox genes (Gsh1 and Cdx2/3), all of them belonging to the ParaHox gene family.The ParaHox gene evolutionary history
