Use of Echinoderms and Marine and Terrestrial Plant Materials in the Technology of Mayonnaise Sauce

Sea urchin caviar is a valuable product, as well as a therapeutic and prophylactic agent for cancer, it removes radionuclides from the body, increases the body’s resistance to various types of infections, with physical and mental fatigue, under stress. In addition to the above mentioned aspects, the ingestion of sea urchin caviar helps to increase the human body’s resistance to adverse and harmful environmental factors, and has a positive effect on the cardiovascular system and thyroid function. The gonads of sea urchins contain a set of all amino acids not synthesized by the human body, moreover, in a ratio close to the composition of the “ideal protein”. The technology for manufacturing a new mayonnaise sauce using such valuable ingredients as sea urchin caviar, kelp, and nettle has been scientifically substantiated and created. A prescription composition of a new product has been developed; samples of mayonnaise sauce were made and their study during storage was carried out. The implementation of such a technology will allow not only rational use of stocks of marine non-fish raw materials and plants, but also expand the range and properties of functional products

Визначення зон стійкості режимів і параметрів руху вібраційних машин різного технологічного призначення

This paper reports a study into the movement of vibratory machines for various technological purposes that determined their stable zones. These zones warrant that the predetermined parameters of energy saving and energy-efficient mode are maintained. The structural scheme of energy transmission within the elements of a vibratory machine has been built. It is common for any design of the vibratory machine and its operating modes. The machine estimation scheme has been constructed taking into consideration a technological load, which is a certain manufacturing environment or a material subject to processing based on the appropriate technology. Underlying the motion equations built is a substantiated discrete-continual model of the vibratory machine and processing environment. The estimation scheme takes into consideration possible structural solutions for a vibratory machine whose movement modes are harmonious or impact-vibrational. The adopted scheme is a resonance vibration-impact system. This study into the movement and establishing the zones of stability has been adapted to simpler and more complex systems by reducing a combined discrete-continual model to the discrete one. The result reveals a qualitative pattern of the vibratory machine movement ensuring the specified mode of its operation. It was found that at the predefined frequency of impacts and weight of a working body, the efficiency of the impact-vibratory machine is determined by the impact speed. The distribution of the basic parameters of such vibration systems has been estimated; stability cards for different zones have been built.This very approach opens up new possibilities for designing highly efficient vibration equipment. A stable resonance mode makes it possible to significantly reduce the energy cost of the manufacturing process and warrant the rational parameters of vibratory machine operation specified by the technology. The results obtained were applied for the development of methods for calculating and constructing a new class of vibratory machines that implement appropriate energy-saving stable zones of the workflowИсследовано движение вибрационных машин различного технологического назначения и установлены устойчивые зоны.

Epidemiology of cardiovascular diseases among patients with diabetes mellitus according to the federal diabetes register of the Russian Federation (2013–2016)

BACKGROUND: Cardiovascular diseases (CVD) are the main cause of death for patients with diabetes mellitus (DM). AIMS: To evaluate the CVD epidemiology: coronary heart disease (CHD), myocardial infarction (MI) and cerebrovascular diseases in adult patients with type 1 (T1DM) and type 2 (T2DM) diabetes, compare dynamics with data of implementation of the Federal Program «Diabetes mellitus» in 2007–2012 and over the online period 2013–2016. MATERIALS AND METHODS: The database of the Federal Diabetes register (81 regions at 12.2017). We estimated prevalence and incidence rates/10 thousand (th) adult DM patients over 18 years. RESULTS: The prevalence of CVD for the period 2007 – 2016 significant decreased in CHD for T1DM from 14,9% to 3,5%, for T2DM from 20,1% to 11,7%; MI for T1DM from 5,7% to 1,3%, for T2DM from 7,6% to 3,5%; cerebrovascular diseases for T1DM from 4,9% to 1,7%, for T2DM from 7,6% to 4,3%, respectively. In 2013→2016 positive trends continued: MI for T1DM 8,2→5,9/10th patients, for T2DM 19,2→14,7/10th patients, respectively; CVD for T1DM 11,3→10,5, for T2DM 29,4→25,4/10th patients, respectively. There was a large heterogeneity of the prevalence of CVD in the regions. MI varied in patients for T1DM from 319/10 th patients to absence, for T2DM from 800 to 7/10 th patients; the development of cerebrovascular diseases for T2DM from 900 to less than 100/10 th patients, which is largely due to differences in their registration. A small number of cases may be due to insufficient filling of the database, the facts of a huge number require further analysis. The average age of development of MI had increased: for T1DM 51,2→53 years, for T2DM 63,5→65 years, cerebrovascular diseases for T1DM 52,3→52.5 years, for T2DM 65,2→66,5, respectively. CONCLUSIONS: The prevalence of CVD significantly decreased in the Russian Federation compared to 2007–2012, as well as for the period 2013–2016: the prevalence of CHD and cerebrovascular diseases declined, the number of new cases of MI decreased, the average age and duration of DM before the development of CVD significantly increased. These data reflect the results of the program for improvement medical care and prevention measures for patients with diabetes
