This paper describes the design of a planar antenna array system with pattern reconfiguration in the azimuthal plane.The antenna array system is designed based on four antenna units where each unit is composed of two printed Yagi-Uda elements that radiate in directional beams over a dedicated sector, thus ensuring maximum isolation with neighboring
The vibration characteristics of a bladed disk with the continuous ring type structure have been studied extensively, and the vibration response analyses considering the friction damping between adjacent shrouds have been performed in the Blood Pressure recent blade design.The effect of the friction damping on the self-excited vibration also has be
An assessment of the species structure and size of small game prey for the spring and autumn-winter hunting seasons on the territory of the Kirov region was made, using a questionnaire survey based on the analysis of the prey of 3220 individuals.Small game includes such species (groups of species) as mallard, Northern shoveler, pintail, teal-whistl
This paper reviews the way in which Spanish agriculture climbed onto the pesticide treadmill.We claim that Fascist policies and expert advice assembled in the early 1940s accelerated the introduction of pesticides into Spanish agriculture and promoted the emergence of the Spanish pesticide industry in the times of autarky.Agricultural engineers wer
Myelomeningocele (MMC), a severe congenital anomaly resulting from neural tube closure defects, poses significant urological challenges necessitating specialized care.This review explores the intricate landscape of MMC within urological practice, advocating for a multidisciplinary approach to optimize patient outcomes.By surveying diverse treatment
