Nowadays, in inter-satellite link systems (ISL), the task of developing radio equipment with high specifications under severe limitations on power consumption and dimensions is relevant. The ...selection of the antenna system type is crucial when addressing this issue. This paper presents a compact waveguide slot antenna for ISL operating in the frequency range of 22.6-23.2 GHz. The paper presents the simulation results of the antenna as well as the developed configuration Nowadays, in inter-satellite link systems (ISL), the task of developing radio equipment with high specifications under severe limitations on power consumption and dimensions is relevant.

Typhoid fever is a dangerous infection. The article analyzes the clinical aspects, diagnostic possibilities and casual treatment of the young men in organized group with typhoid. It's shown that ...despite early hospitalization (at average of 5.5 days) the main manifestations peculiar to the "classical" infection retained. The majority (61.5%) had disease of moderate severity, mild form were at 37,4% of patients. Complications occurred in 5.0% of the patients: pneumonia (2.8%), myocarditis (2.2%) and pancreatits (2.2%). Pathogen isolated from patients with typhoid fever had reduced susceptibility to fluoroquinolones. Antimicrobial therapy showed the advantage of the 3 generation cephalosporin (ceftriaxone) compared with ciprofloxacin or a combination of the latter with cefotaxime.
The results of a long-term study of the apple tree gene pool ( Malus x domestica Borkh.) in the conditions of southern Russia are presented. The purpose of the study is the formation of the ...identified collections, the selection of donors and sources of economically valuable traits with recommendations for their use in apple breeding. In the work we used the programs and methods of breeding and sorting, molecular genetic research methods. Valuable for breeding cultivars with immunity to scab ( Rvi6 gene) and high quality of fruits (genes Md-PG1 (AA); Md-Exp7 (198)) were identified: Modi, Stellar, CIVG 98, elite form 29-5-49.
Analytical investigations of workloads of the RUP «BMZ» mill 320 working stands at rolling of fittings of slugs with section 140´140 mm using the system of minimum tension are carried out.
Light optic and ultrastructural examinations of neutrophilic phagocytosis in patients with phlegmons in test system revealed morphological changes in the cells. The changes were proposed by the ...authors to be regarded as a criterion for assessing the antibacterial resistance of the body. Moreover, a unique approach was developed to the overall assessment of phagocytic indices, providing characterization of two neutrophilic performance types: balanced and extensive. When neutrophils begin to function extensively, this may be considered as a reflection of their relative functional inadequacy.
