Public management of public healthcare under the COVID-19 outbreak: experience of Ukraine.

Objective: Aim: The research is aimed to study certain aspects and experience of functioning of the Ukrainian Public Healthcare public management mechanisms during an outbreak of the acute respiratory disease COVID19.

Patients And Methods: Materials and Methods: The studied materials include personal observations and accumulated practical material, as well as generalization of the collected data and their empirical treatment, conducted by the scientists, according to the present legislation requirements. The study was held using general scientific methods, including observation, description of results, specification and statistical data generalization.

Comparative characteristics of the genetic structure of the Syrian cattle breed compared to Holstein and Aberdeen-Angus breeds.

Objectives: The objective of this study was to perform a comparative analysis of allelic diversity to reveal population-genetic characteristics of animal breeds, namely Shami (SH), Holstein (HLS), and Aberdeen-Angus (A-A).

Materials And Methods: The genetic materials of SH breed animals represented by wool with hair follicles were collected from 39 SH heads in Syria. Also, genetic materials of HLS breed of American selection ( = 55, HLS) and bulls and cows of A-A breed bred at breeding enterprises in Russia ( = 30, A-A) were collected.

Computer-aided detection of acute pulmonary embolism with 64-slice multi-detector row computed tomography: impact of the scanning conditions and overall image quality in the detection of peripheral clots.

Purpose: To evaluate the performance of a computer-aided detection (CAD) system for diagnosing peripheral acute pulmonary embolism (PE) with a 64-slice multi-detector row computed tomography (CT).

Materials And Methods: Two radiologists investigated the accuracy of a software aimed at detecting peripheral clots (PECAD prototype, version 7; Siemens Medical Systems, Forchheim, Germany) by applying this tool for the analysis of the pulmonary arterial bed of 74 CT angiograms obtained with 64-slice dual-source CT (Definition; Siemens Medical Systems). These cases were retrospectively selected from a database of CT studies performed on the same CT unit, with a similar collimation (64 x 0.

Thermodynamic approach to the description of dislocation mobility in quasicrystals.

Dislocation mobility in quasicrystals is calculated using basic thermodynamic and hydrodynamic equations. The dependence of the dislocation mobility on viscosity, vacancies and phasons is given. It is shown that the phasonic defects make the major contribution to the inverse mobility of the free segments of dislocations.

Computer-aided measurements of pulmonary emphysema in chest multidetector-row spiral computed tomography: effect of image reconstruction parameters.

Objective: To evaluate the effect of different image reconstruction parameters on quantitative automated measurements of pulmonary emphysema in chest multidetector-row spiral computed tomography.

Materials And Methods: Thirty patients with known emphysema underwent multidetector-row spiral computed tomography. Retrospective reconstruction with a soft tissue kernel (Siemens B20 at 1-mm, 2-mm, and 3-mm slices) and 4 alternative kernel grades (from smooth to sharp: Siemens B30, B40, B50, B60 at 1-mm slices) was performed.
