Problems of the absence of regulatory and legal acts regulating the conditions and rules for repair of measuring equipment are presented.

The article is devoted to solving problems related to the slow pace of development of container transportation due to lack of specialized terminal complexes, construction of which requires large capital investments, as well as specialized delivery equipment. The article substantiates the need for greater attention to improvement of container transportation technology as the most promising way to deliver cargo in direct and mixed traffic. A description of a new design of a transportable container with load lifting pillars is given, the use of which will improve the organization of container transportation.

This paper develops a general approach to the derivation of the boundary conditions for hydrodynamic equations for charged and neutral plasma components. It includes both a well-known classical case for pure diffusion, and considers the expressions for diffusion and drift together - for an absorbing (neutralizing) wall with partial reflection and the possible emission of plasma components. Some unclear and controversial terms found in the existing literature are clarified. Several examples of applications of the results, which illustrate the properties of boundary conditions for electrons and ions, are calculated and analyzed., This is a revised version of our paper that was primarelly submitted to Physical Review E - 2018, November, 24. Now it is published in Physics of Plasmas 27, 1 (2020). After publication, a mistake in the Sample IV.C is corrected

The analysis of heat transfer design methods in condensing inside plain tubes under existing influence of shear stress is presented in this paper. The existing discrepancy in more than 30-50% between rating heat transfer coefficients and experimental data has been noted. The analysis of existing theoretical and semi-empirical methods of heat transfer prediction is given. The influence of a precise definition concerning boundaries of phase flow (it is especially important in condensing inside horizontal tubes), shear stress (friction coefficient) and heat flux on design of heat transfer is shown. The substantiation of boundary conditions of the values of parameters, influencing accuracy of rated relationships, is given. More correct relationships for heat transfer prediction, which showed good convergence with experiments made by different authors, are substantiated in this work., {"references":["W.

The article deals with the issue of formation of the xenobiotic profile of a biogeocenosis as a combination of foreign substances in the environment in a form that allows them to enter into chemical and physicochemical interactions with biological objects of the ecosystem. At the initial stage, patterns of distribution of xenobiotics in various natural environments (water, soil, air, and living organisms) and their subsequent effects on the biogeocenosis were determined.

In the work lists the methods of the research of heat transfer of the flow of natural gas in pipes with longitudinal fins and the experimental setup.

This work presents a laboratory model ice machine, designed to test the possibility of its creation, as well as clarification of the preliminary assessment of the thermal characteristics necessary for the design of ice machine.

A sufficient condition for the existence of a solution to the Gorin integral equation for a nonlocal source of ionization in a dc glow discharge of an arbitrary geometry, including a hollow-cathode glow discharge, is formulated and proved. Together with the theorem of uniqueness of solution, stated and proved earlier, this provides reliable mathematical basics for simulating nonlocal phenomena using convenient physically meaningful structures.

Ninety patients aged 41 to 68 years with the chronic patterns of coronary heart disease (CHD) were examined for the content of triiodothyronine (T3), total T4 and free thyroxine (FT4), thyrotropic hormone (TTH), adrenocorticotropic hormone (ACTH), and insulin. At the same time the patients were examined with the aid of the glucose tolerance test, determination of blood concentration of cholesterol, triglyceride, high density lipoprotein cholesterol, fibrinogen and soluble fibrin. The patients with CHD showed a decrease in the basal level of T3, T4, FT4 and elevation of TTH, ACTH and insulin in blood. A correlation was found between the basal of insulin and thyroid hormones and lipid metabolism in CHD patients. It was shown that thyroid hypofunction, unmarked clinically but detectable by the lowering of the content of thyroid hormones and rise of thyrotropic hormone in blood of CHD patients, might promote the development of hyperinsulinemia.

In 16 male subjects, the hepatic absorption-excretion function and the gallbladder and biliary ducts were investigated using computer scintigraphy and 99mTs-HIDA. Comparison of the data obtained after 6-hour (-20 degrees) and 3-day (10 degrees) antiorthostatic hypodynamics with the baseline data obtained in the supine position demonstrated deterioration of the absorption-excretion function of the liver. In response to a short-term exposure (6 hour) the changes were seen only in subjects with latent or clinically nonmanifest pathologies of the digestive organs. As the exposure continued, changes in the hepatobiliary function became more manifest and significant. It is recommended to study in greater detail changes in the above function and their involvement in the symptom complex of an acute stage of adaptation to microgravity.

Blood vasopressin, tri-iodothyronine, total thyroxine, thyrotrophic hormone, cortisol, ACTH and insulin levels were measured in 60 chronic coronary patients aged 35 to 70. Coronary patients showed elevated blood vasopressin, particularly in the presence of frequently recurring anginal attacks. There was no significant difference in vasopressin levels of patients with and without attendant essential hypertension, those with atherosclerotic and postinfarction cardiosclerosis, or in relation to body weight. Insulin, cortisol, adrenocorticotrophic and thyrotrophic hormones were significantly increased, and tri-iodothyronine and total thyroxine, significantly decreased, in coronary patients as compared to the controls.

Thirty-eight men with chronic coronary heart disease (CHD) aged 38 to 65 years (ten patients with attendant obliterating atherosclerosis of lower extremity vessels) were treated with the hypolipidemic drug probucol in a dose of 1000 mg/day for three months. Probucol exerted a beneficial effect on the clinical course of CHD and obliterating atherosclerosis of the lower limb vessels. The drug has a marked hypocholesterolemic effect in CHD patients with high cholesterol levels in the blood serum which warrants the advisability of its use in type IIa and IIb hyperlipoproteinemia. The probucol therapy is associated with a decrease in the cholesterol/erythrocyte membrane phospholipids molar ratio which improves the rheological properties of the blood in CHD patients. The drug produces no side effects.

Changes in blood insulin, thyroxine, triiodothyronine, thyrotropin, somatotropin, corticotropin, cortisol, and aldosterone were defined in 46 male patients with coronary heart disease during daily graded exercises performed on a bicycle ergometer for 30 days. The exercises led to improvement of health in 44 patients. There was a significant reduction in baseline insulin and aldosterone levels and a tendency to lower corticotropin and triiodothyronine concentrations. The amounts of somatotropin, thyrotropin, thyroxine, and cortisol failed to greatly change during the exercise.

Nirmin, a novel dosage form of nitroglycerin, was used to treat heart failure in 47 patients on days 1-3 after acute myocardial infarction. The drug was intravenously injected at 12-400 micrograms/min for 3-24 hours. Central hemodynamic changes were evaluated from equilibrium radionuclide ventriculographic data and pulmonary diastolic and central venous pressures. Nirmin improved the clinical status in 89.3% of the patients. Hemodynamic effects of the agent were manifested by reduced myocardial preload and its improved contractility, followed by elevated left ventricular ejection fraction and decreased hypokinesia of the myocardial affected areas.

The authors proposed a method of cholescintigraphy with functional imaging reflecting RP distribution within the entire area in the field of vision of a gamma-chamber detector taking account of the type of motor activity of the gall bladder. This method was based on plotting an activity-time curve along the outer contour of a gall bladder image, the determination of moments of change in gall bladder motor activity on this curve, and the calculation of corresponding gradients of RP accumulation and clearance functions represented on an image where the color of each element was determined by a sign of the gradient and its intensity--by its absolute value. The use of this method in 92 patients made it possible to reveal conditions with possible B-bile reflux into the intrahepatic ducts, and to raise its diagnostic accuracy by 7% as compared to a routine analysis of activity-time curves by decreasing the number of false-negative results.

The motor activity of the gall bladder was studied using cholescintigraphy with 99m Tc-HIDA in 57 patients with chronic cholecystitis and chronic hepatitis and in 9 controls. A comparative analysis of the curves activity-time based upon the elements of images of the external contour and the entire zone of the gall bladder, made it possible to reveal differences in the type of reaction of the gall bladder to the use of cholagogic stimulators (cholecystokinin i.v. and cholagogic breakfast). A method of the processing of the results made it possible to determine the number of contraction phases of the gall bladder during its emptying as well as the true latent period and the period of primary reactions of the biliferous apparatus after taking a food stimulus.

Seventy-five patients with chronic coronary heart disease (CHD), aged 41 to 65 years, were studied for levels of triiodothyronine, total and free thyroxin and immunoreactive insulin. Simultaneously, the glucose tolerance test was carried out and blood concentrations of cholesterol, triglycerides, high density lipoprotein cholesterol, fibrinogen and disoluble fibrin were determined. Patients with CHD displayed decreased basal levels of triiodothyronine, total and free thyroxin and increased concentrations of immunoreactive insulin in the blood which was attended with decreased tolerance to glucose. These hormonal disturbances resulted in an elevation in cholesterol, triglycerides and fibrinogen. CHD patients showed an inverse correlation between cholesterol and free thyroxin levels and a direct relationship between triglycerides and immunoreactive insulin.

The time evolution of an incompressible non-ideal magnetohydrodynamic (MHD), current-carrying plasma with mass flow is investigated. An approach for the reduction of the nonlinear vector MHD equations to a set of scalar partial differential equations is supposed. Analytical time-dependent solutions of this system are presented. They describe kinetic plasma equilibria both with well-defined nested-in magnetic and velocity surfaces and in the form of vortices. The obtained solutions may be called ‘diffusion-like’, since their temporal structure is very similar to the solutions of the diffusion problem. It is shown that the magnetic field and the velocity have different dumping rates. In the asymptotic limit t→∞, the plasma slowly relaxes towards the hydrostatic equilibrium of gravitating systems.
