Introduction: based on the analysis of the known literature, it is shown that modern course-glide systems have disadvantages associated with the presence of copyright signal generators in them, the lack of frequency and spatial selection of the signal and interference.The purpose of the work: to develop the principles of constructing a promising no
It is well known that food and energy requirement for human beings is increasing day by day due to the fast increase of population in the world.This can be met by (i) increasing the yield of crop per unit area, (ii) post-harvest losses, and (iii) using the barren land, which is about 19% for crop/vegetable production.The barren land consists of the
Objectives.Determine particulate matter (PM10) and heavy metals concentrations in the environment, as well as in surrounding communities of the Las Bambas project after five years of mineral exploration.Materials and methods.A comparative cross-sectional study was conducted in three districts in the area of influence of the Las Bambas project in Ap
The study of the influence factor of transmission line scattering and its influence law is the key to developing the transmission line passive interference suppression strategy.Therefore, the line-surface geometric model of electromagnetic scattering of transmission lines is constructed in this paper.The method of moments (MOM) built in Feko simula
Barley mild mosaic virus (BaMMV), Barley yellow mosaic virus (BaYMV) and Barley yellow GRUNDIG GWDI854 Integrated 8 kg Washer Dryer dwarf virus (BYDV) have been identified as an important causative agents for an economically important disease of winter barley in Korea.In this study, a multiplex reverse transcription polymerase chain reaction (mRT-P
