Development of a grinding device for producing coal powder-raw materials of coal-water fuel
This article proposes a method for grinding coal based on the use of the energy of a pulsed shock wave resulting from a spark electric discharge in a liquid. The main purpose of the scientific work is the development of an electric pulse device for producing coal powder, the main component of coal-water fuel. The diameter of the initial coal fraction averaged 3 mm, and the size of the resulting product was 250 μm. To achieve this goal, the dependence of the length of a metal rod electrode (positive electrode) on the length and diameter of its insulation is investigated. Various variants of the shape of the base (bottom) of the device acting as a negative electrode are considered, and an effective variant based on the results of coal grinding is proposed. An experimental electric pulse installation is described, the degree of coal grinding is determined depending on the geometric parameters. The optimal characteristics of the obtained coal powder have been established
Triple Immunochromatographic System for Simultaneous Serodiagnosis of Bovine Brucellosis, Tuberculosis, and Leukemia
An immunochromatographic test system has been developed for the simultaneous rapid multiplex serodiagnostics of bovine brucellosis, tuberculosis, and leukemia. The test system is based on the use of a conjugate of gold nanoparticles with the chimeric protein Cysteine-A/G and three analytical zones with immobilized pathogen antigens: Brucella abortus lipolysaccharide, recombinant proteins MPB64 and MPB83-MPB63 of Mycobacterium bovis, and recombinant protein p24 of the bovine leukemia virus. Prototypes of the test system were tested on 98 samples of sera from healthy and infected animals. The diagnostic sensitivity of the developed test system was 92% for brucellosis, 92% for tuberculosis, and 96% for leukemia. False positive test results were not observed
Management of dyslipidaemia in patients with coronary heart disease: Results from the ESC-EORP EUROASPIRE V survey in 27 countries
WOS: 000468732700018PubMed ID: 31054483Background and aims: One of the objectives of the ESC-EORP EUROASPIRE V survey is to determine how well European guidelines on the management of dyslipidaemias are implemented in coronary patients. Methods: Standardized methods were used by trained technicians to collect information on 7824 patients from 130 centers in 27 countries, from the medical records and at a visit at least 6 months after hospitalization for a coronary event. All lipid measurements were performed in one central laboratory. Patients were divided into three groups: on high-intensity LDL-C-lowering-drug therapy (LLT), on low or moderate-intensity LLT and on no LLT. Results: At the time of the visit, almost half of the patients were on a high-intensity LLT. Between hospital discharge and the visit, LLT had been reduced in intensity or interrupted in 20.8% of the patients and had been started or increased in intensity in 11.7%. In those who had interrupted LLT or had reduced the intensity, intolerance to LLT and the advice of their physician were reported as the reason why in 15.8 and 36.8% of the cases, respectively. LDL-C control was better in those on a high-intensity LLT compared to those on low or moderate intensity LLT. LDL-C control was better in men than women and in patients with self-reported diabetes. Conclusions: The results of the EUROASPIRE V survey show that most coronary patients have a less than optimal management of LDL-C. More professional strategies are needed, aiming at lifestyle changes and LLT adapted to the need of the individual patient.ESC - EORP; AmgenAmgen; Eli LillyEli Lilly; PfizerPfizer; SanofiSanofi-Aventis; Ferrer; Novo NordiskNovo NordiskThe EUROASPIRE V survey was carried out under the auspices of the ESC - EORP.

Management of dyslipidaemia in patients with coronary heart disease: Results from the ESC-EORP EUROASPIRE V survey in 27 countries
Background and aims: One of the objectives of the ESC-EORP EUROASPIRE V
survey is to determine how well European guidelines on the management of
dyslipidaemias are implemented in coronary patients.
Methods: Standardized methods were used by trained technicians to
collect information on 7824 patients from 130 centers in 27 countries,
from the medical records and at a visit at least 6 months after
hospitalization for a coronary event. All lipid measurements were
performed in one central laboratory. Patients were divided into three
groups: on high-intensity LDL-C-lowering-drug therapy (LLT), on low or
moderate-intensity LLT and on no LLT.
Results: At the time of the visit, almost half of the patients were on a
high-intensity LLT. Between hospital discharge and the visit, LLT had
been reduced in intensity or interrupted in 20.8\% of the patients and
had been started or increased in intensity in 11.7\%. In those who had
interrupted LLT or had reduced the intensity, intolerance to LLT and the
advice of their physician were reported as the reason why in 15.8 and
36.8\% of the cases, respectively. LDL-C control was better in those on
a high-intensity LLT compared to those on low or moderate intensity LLT.
LDL-C control was better in men than women and in patients with
self-reported diabetes.
Conclusions: The results of the EUROASPIRE V survey show that most
coronary patients have a less than optimal management of LDL-C. More
professional strategies are needed, aiming at lifestyle changes and LLT
adapted to the need of the individual patient
