In this research, an active antenna operated at the second harmonic frequency is investigated, and is implemented using microstrip antenna material.The antenna consists of a FET oscillator which plays as a fundamental frequency oscillator and a frequency multiplier, and a patch antenna resonated at the second harmonic frequency as the radiator.A ma
ObjectiveTo simplify the ship modeling process and improve modeling efficiency, this paper proposes a method for rapidly implementing hull model creation based on hull line drawing.MethodsUsing the CATIA platform, this method adopts the component application architecture (CAA) development tool for secondary development.First, by reading the geometr
P.aeruginosa strain FG106 was isolated from the rhizosphere of tomato plants and identified through morphological analysis, 16S rRNA gene Flange Nut sequencing, and whole-genome sequencing.In vitro and in vivo experiments demonstrated that this strain could control several pathogens on tomato, potato, taro, and strawberry.Volatile and non-volatile
Energy poverty alleviation has emerged as a critical economic problem in recent years.Given the enormous number of people without essential energy services, a crucial concern is whether providing universal access to electrification will considerably affect environmental quality.The present research evaluates Outdoor Dining Chair (Set of 2) the asym
