An arc-shaped distributed multilayer capacitive loading structure combined with resistive loading is presented in this paper to enhance the radiation performance of folded bowtie antenna (FBA).The radiation efficiency of the loaded bowtie antenna (BA) is improved, and the low-frequency bandwidth is broadened by the bent loop circuits.Additionally,
Objective: To differentiate clear cell and non-clear cell renal cell carcinoma (RCC) using enhancement pattern, relative enhancement ratio and associated findings on CT scan.Methods: This retrospective study reviewed CT scan in the unenhanced, corticomedullary and nephrographic phase in clear cell and non-clear cell RCC.A total of 49 patients with
This paper is a novel attempt to combine two important aspects of fuel cell (FC).First, it presents investigations on FC technology and its applications.A description of FC operating principles is followed by the comparative analysis of the present FC technologies together here with the issues concerning various fuels.Second, this paper also propos
Camellia oleifera is an important woody oil species in China.Its seed oil has been widely used as a cooking oil.Seed size is a crucial factor influencing the yield of seed oil.In this study, the horizontal diameter, vertical diameter and volume of C.oleifera seeds altitude sunscreen showed a rapid growth tendency from 235 days after pollination (DA
Sea urchin (Loxechinus albus) is one of the most economically important species in the northeast of Chilean Patagonia, forming part of the highly diverse benthic community.This resource is being harvested under selective fishing pressure, which suppresses growth rates.In response, the National Standards Institute established Regulation 44 as a qual
