Study of the Spectral Characteristics of Crops of Winter Wheat Varieties Infected with Pathogens of Leaf Diseases.

Studying the influence of the host plant genotype on the spectral reflectance of crops infected by a pathogen is one of the key directions in the development of precision methods for monitoring the phytosanitary state of wheat agrocenoses. The purpose of this research was to study the influence of varietal factors and disease development on the spectral characteristics of winter wheat varieties of different susceptibility to diseases during the growing seasons of 2021, 2022 and 2023. The studied winter wheat crops were represented by three varieties differing in susceptibility to phytopathogens: Grom, Svarog and Bezostaya 100.

MATHEMATICAL JUSTIFICATION OF THE CHOICE OF RODS FOR EXTERNAL FIXATION DEVICES FOR POLYSTRUCTURAL PELVIC INJURIES.

Aim - In order to fulfill the purpose of biomechanical substantiation for extrafocal pelvic osteosynthesis in osteoporosis we studied the stress-strain state (SSS) of LEG under conditions of external fixation by apparatuses with cylindrical and conical rods. Studies of the stress-strain state of the lower extremity belt by the finite element method were carried out under conditions of external fixation by devices with cylindrical and conical rods. In the finite element method, the approximate solution is constructed as a superposition of approximating functions.

[Complex treatment of patients with the diabetic foot].

To improve a complex surgical treatment of patients with the diabetic foot (DF), 46 patients with examined and treated this condition were. According to the treatments used, the patients were divided into 2 groups: study and control ones. The study group (n = 28) received current complex treatment using laser and immune therapies.

[Radionuclide hepatobiliscintigraphy in prediction of the Buchwald's operation effect].

The authors have proposed a method for predicting the effect of Buchwald's operation (partial iliac bypass surgery) and successfully tested it in 32 patients with hyperlipidemia. The method is based on pharmacological simulation of major pathophysiological intervention points verified by radionuclide hepatobiliscintigraphy. Evaluating lipid metabolic changes before and after simulation serves as a basis for predicting the effect of the operation.
