In 1963 Ridley postulated that under certain bias conditions circuit elements exhibiting a current- or voltage-controlled negative differential resistance will separate into coexisting domains with different current densities or electric fields, respecti
The present work is a survey on aircraft hybrid electric propulsion (HEP) that aims to present state-of-the-art technologies and future tendencies in the following areas: air transport market, hybrid demonstrators, HEP topologies applications, aircraft design, electrical systems for aircraft, energy ...
The Electronic structure of PbPdO2 with (002) and (211) preferred orientations were investigated using first-principles calculation. The calculated results indicate that, (002) and (211) orientations exhibit different electric field dependence of band-ga
Hedysarum leave Maxim was treated for 5 min with different frequencies and different intensities in uniform electric field respectively,and the effect of electric field on its germination percentage and on the roots were tested. Results showed the germination percentage of Hedysarum leave Maxim was in...
As the current density of the activated carbon nanofiber-800 is much larger than that of carbon nanofiber, the specific capacitance (and electric energy) stored in the activated carbon nanofiber-800 is much larger than that of the activated carbon nanofiber. The much higher current density of ...
electric current system, which involves regions both very near to the pulsar and very far away in the pulsar wind, a problem for which no general agreement exists as to its solution. The relative importance of the magnetic and kinetic energy flows is conveniently written as the magnetizationσ:...
Pulsed electric fields (PEF) can affect enzyme activity in fruit and vegetable juice, but its effect on microbial cellular enzymes has not been fully revealed. Alcohol dehydrogenase (ADH) is a key cellular enzyme of Acetobacter sp. to convert alcohol to acetic acid by metabolism. In this study...
The current study’s importance comes from its contribution to the control and operation of agricultural vehicles powered by electric batteries, as this aspect is poorly covered by the literature, while also considering the interest in electric tractors and electric vehicles in general. The purpose of...
As previously said, being the observations in the bottom-side ionosphere analogous to the effects induced by solar flares (Solar Flare Effect - SFE)45,46, we investigated the possibility of a sudden intensification of the Solar quiet (Sq) ionospheric current system47,48and of the ionospheric Equ...
Most of the ongoing projects aimed at the development of specific therapies and vaccines against COVID-19 use the SARS-CoV-2 spike (S) protein as the main target. The binding of the spike protein with the ACE2 receptor (ACE2) of the host cell constitutes
