Aim To evaluate effectiveness of preventive telephone counseling with a nutritional component and distance support for three months with respect of motivation for lifestyle modification in patients with high and very high cardiovascular risk (CVR).Material and methods This prospective, controlled, randomized clinical study in two parallel groups included patients with high and very high CVR (5–9 % and ≥10 % according to the SCORE scale) who had at least two criteria of metabolic syndrome. Patients were randomized to the main and control groups in a 1:1 ratio with age and gender stratification. The main group received comprehensive preventive counseling with a nutritional component and distant support via telephone once in two weeks for three months (total 6 consultations). Patients of the control group received standard counseling by a health center physician. Patients’ motivation for lifestyle changes was evaluated with a questionnaire at baseline and at 6 and 12 months.Results The study included a total of 100 patients (mean age, 59.85±4.47 years, 80 % females). At baseline, 81 % of patients had high and 19% of patients had very high CVR. Patients of the study groups did not differ in major demographic and clinical characteristics. At 6 month of follow-up, the main group showed a significantly more pronounced positive changes in motivation and healthier lifestyle (50 % in the main group vs. 12% in the control group, р<0.01). At 12 months of follow-up, the number of such patients somewhat decreased to 38%. In this process, a vast majority of patients in the control group (82 %) continued theoretically considering the expediency of lifestyle modification.Conclusions Preventive counseling with nutritional component and further distance support via telephone for three months for patients with high and very high CVR provided increased motivation for healthier lifestyle and positive behavioral changes.

Published: June 2020

Aim To determine the role of left ventricular segmental (SLS) and general longitudinal strain (GLS) in early diagnosis of acute coronary syndrome (ACS).Material and methods The study included 112 patients aged 58±7 years with suspected ACS without a history of ischemic heart disease (IHD) who were admitted to the hospital within 12 h of complaint onset. The control group consisted of 20 healthy, age- and sex-matched subjects. Speckle-tracking echocardiography was performed to assess SLS and GLS on admission and discharge. Ischemia was diagnosed when the SLS was decreased to 14% or lower with a simultaneous post-systolic shortening (PSS) of these segments >20% or when the initial lengthening of the segments was followed by PSS.Results Decreased SLS with PSS of one or more segments was observed in 51.8 % of patients; 16.1% of patients had initial systolic lengthening of one or more segments followed by PSS. In 30.3 % of patients, GLS was 15.5 % or less; 82.3% of these patients had SLS disorders. Later, ACS was diagnosed in 72.3 % of the patients. ACS was not confirmed in 4 (5.2%) of 76 (67.9 %) patients with abnormal SLS changes. All these patients had low SLS values and high PSS values and did not have the initial systolic segmental lengthening. Seven of 9 (8 %) patients with false-negative SLS values had distal narrowing of a coronary artery and two patients had narrowing in the middle part of the artery. All patients with ACS and decreased GSL had a hemodynamically significant narrowing of more than one coronary artery. Incidence of two and more stenosed arteries was higher in patients with PSS and low GSL. Sensitivity and specificity of SLS for diagnosis of acute ischemia were 88.9 and 84.6 %, respectively.Conclusion Assessment of LV strain has high sensitivity and specificity for diagnosis of ACS in patients with the first IHD episode. The presence of PSS associated with decreased GSL may indicate multivascular IHD.

Authors: Farzan Mahmoud , Farhoud Amirreza , Zarei Mohammad , Mohammed Yaseen Khan Furqan , Dehghani-Firoozabadi Mohammed Javad
Published: June 2020

Background: Osteoid osteoma (OO) is a benign osteoblastic neoplasm, mostly occurring in long bones of lower extremity. Its manifestation in unusual locations can be a diagnostic challenge and distressing for patients. OO in carpal bones is uncommon; its occurrence in triquetrum is even more so.
Case Presentation: This study reports on a nineteen-year-old female with history of wrist pain for 4 years. She had sustained trauma to the same wrist before commencing of pain. Patient's pain was unresponsive to conservative treatments. Her routine x-rays were mostly interpreted as normal and obtaining further imaging helped us in diagnosis of OO of triquetrum. Surgical resection of the nidus was performed.
Conclusions: Manifestation of OO in small carpal bones may not be typical; identifying the lesion or nidus could be challenging. Whatever unusual the location or presentation of such lesions may be, obtaining advanced imaging can be of significant help; therefore, we suggest clinicians to have low threshold in ordering advanced imaging specifically in patients suffering from chronic pain. Also, persistent history of nocturnal pain is a sign which is worth attention.

HEART RATE MONITOR USING INFRARED
Authors: Parmar Divyesh , Mistry Rishi , Kava Yash
Published: June 2020

The heart rate is one of the significant physiological parameters of the human cardiovascular system. Heart rate is the number of times the heart beats per minute. Heart rate data reflects various physiological states such as biological workload,stress at work and concentration on tasks, drowsiness and the active state of the autonomic nervous system. Human cardiac dynamics are driven by the complex nonlinear interactions of two competing forces: sympathetic regulation increases and parasympathetic regulation decreases the heart rate. Thus,monitoring of heart rate plays a significant role in providing the status of cardiovascular system and clinically correlated information to medical professionals. Heart rate measurement is also regarded as an essential parameter in patient care monitoring system. Heart rate can be measured either by the ECG waveform or by sensing the pulse - the rhythmic expansion and contraction of an artery as blood is forced through it by the regular contractions of the heart. The pulse can be felt from those areas where the artery is close to the skin. This paper highlights on the design of a microcontroller (PIC series) based heart rate counter that is able to capture the pulse from finger tip by sensing the change in blood volume. The heart rates of fifteen healthy normal subjects (students of age 21-22 yrs.) both in relaxed and excited states were measured using the designed device and a standard heart rate measuring device. The outputs of the measured device were satisfactory. Also, the designed device,being noninvasive one, can easily find its place in health care monitoring system.

This paper aims to improve the quality of the patient's life and provide them with the lifestyle they need. And we have the intention to obtain this by creating a mobile application that analyzes the patient's data such as diabetes, blood pressure, and kidney. Then, implement the system to diagnose patients of chronic diseases using machine learning techniques such as classification. It's hard for the patients of chronic diseases to record their measurements on a paper every time they measure either the blood pressure or sugar level or any other disease that needs periodic measurements. The paper might be lost, and this can lead the doctor not fully to understand the case. So, the application is going to record measurements in the database. Also, it's difficult for patients to decide what to eat or how many times they should exercise according to their situation. Our idea is to recommend a lifestyle for the patient and make the doctor participate in it by writing notes. In this paper, machine learning classifiers were used to predict whether the person is prone to some chronic diseases. Blood pressure, diabetes and kidney are considered in this work. Orange3 from Anaconda-Navigator is the data mining tool used to test some machine learning algorithms. Blood pressure is the amount of force that blood exerts on the walls of the arteries as it flows through them. When this pressure reaches high levels, it can lead to serious health problems. For hypertension, Tree algorithm has shown 100% accuracy, which was the best one. Chronic Kidney Disease (CKD) is a significant public health concern with rising prevalence. With a set of considered attributes such as specific gravity, albumin, serum creatinine, hemoglobin, packed cell volume and hypertension used to predict if the person has Kidney disease or not. For kidney, Random Forest algorithm has shown 100% accuracy, which was the best one among other algorithms tested. Diabetes is a chronic disease when it cannot the pancreas to produce insulin, or when the body cannot use the insulin the pancreas produced. We considered attributes such as pregnancies, glucose, blood pressure, skin thickness, insulin, diabetes pedigree function, age and BMI of a person to diagnose whether a patient has diabetes based on specific diagnostic measurements or not. For diabetes, neural networks have shown the best accuracy. It was 76.3%.

The article presents the study of several machine learning algorithms that are used to study breast cancer data with 33 features from 569 samples. The purpose of this research is to investigate the best algorithm for classification of breast cancer. The data may have different scales with different large range one to the other features and hence the data are transformed before the data are classified. The used classification methods in machine learning are logistic regression, k-nearest neighbor, Naive bayes classifier, support vector machine, decision tree and random forest algorithm. The original data and the transformed data are classified with size of data test is 0.3. The SVM and Naive Bayes algorithms have no improvement of accuracy with random forest gives the best accuracy among all. Therefore the size of data test is reduced to 0.25 leading to improve all algorithms in transformed data classifications. However, random forest algorithm still gives the best accuracy.

The 5p inverted duplication deletion syndrome, also known as inv dup del 5p, is a rare genetic disorder with a prevalence of below 1:1 000 000, whose underlying abnormality lies in a segmental trisomy and simultaneous segmental monosomy of the short arm of chromosome 5. The syndrome was first described by A. Kleczkowska et al. in 1987. According to the literature, large duplications of the chromosome 5 short arm are associated with pronounced phenotypic manifestations, delayed speech and mental development, as well as congenital cardiac, brain and musculoskeletal malformations. We present a description of a clinical case of extended inverted duplication with deletion of the chromosome 5 short arm in a girl with a mild phenotype and no visceral or musculoskeletal abnormalities; we also discuss the pathogenetic mechanisms of chromosomal rearrangement, and conduct a comparative analysis of phenotypic manifestations based on the available literature. Comprehensive molecular cytogenetic assessments have demonstrated that the duplicated site has a length of 29 Mb (5p13.3p15.33), and the deleted site of the subtelomeric region distal to 5p15.33 has a length of 110 kb.

Published: June 2020

This study presents the results of the effect of a dry powder obtained from Antonovka apples growing in the Kursk region on the composition of sugars in crispbread. In the crispbread recipe, whole wheat and rye flour was partially replaced by apple powder in the amount of 10, 15 and 20%. The vibrations of the characteristic frequencies of organic compounds were obtained using infrared spectroscopy, this way it possible to identify the characteristic frequencies of functional groups. Studies show that apple products contain malic acid, which accounts for 72-82% of the total amount of acids. Also, raw apple materials contain citric acid, which accounts for about 2-4% and succinic – 6-9%. Volatile acids in an amount of 1-4% are found in malic powder. In the test with the addition of apple powder, the initial acidity increases and the content of volatile acids also increases but only slightly. It has been experimentally established that the introduced additional raw materials stimulate the fermentation process of the dough. At the same time, the duration of the ripening test is reduced to 30-40 minutes, and the duration of the proofing is equal to 15 minutes. A comparative analysis of the IR spectra of apple powder and three samples of bread (with a content of 10, 15 and 20% of apple powder) and monosaccharides showed the following monosaccharide composition: the presence of galactose, arabinose, mannose and, presumably, sucrose. The data obtained during the study corresponds fairly well with the literature data on the monosaccharide composition. Studies have shown that using the method of IR spectroscopy, the monosaccharide composition of the product can be obtained in a quite simple and fast way.

Influence of cationic surfactants on physical and mechanical properties of polymer compositions
Authors: Shmakova N. S. , Kirsh I. A. , Romanova V. A.
Published: June 2020

When creating filled polymer composite materials, difficulties often arise due to poor compatibility of polymers with modifying additives. To solve such problems, surface-active substances (SAS) are successfully used in many industries, but they are practically not used in polymer processing. This is largely due to the insufficient assortment of surfactants produced that are suitable for introduction into polymers, especially film-forming ones. Anionic and nonionic surfactants are used in the synthesis and processing of elastomers, but they are not used in the production of film materials. As for the use of cationic surfactants, there are still no data at all. They differ from other types of surfactants in a variety of structures, in the number and relative positions of cationic centers and hydrophobic radicals, and also in antimicrobial properties. The prospects of using quaternary ammonium salts for the modification of packaging materials are shown. The expediency of using cationic surfactants for the modification of polymeric materials is proved. It is shown that the use of quaternary ammonium salts improves the physical and mechanical properties of films based on polyethylene and polypropylene. It is proved that cationic surfactants are technologically compatible with polyolefins, which allows the processing of polymer compositions by extrusion. Today, the most common polymers for food packaging are polyethylene and polypropylene. This is due to their low cost, safety in contact with food products, and suitability for processing into films of different thicknesses. More and more attention is being paid to the creation of packaging materials with antimicrobial properties. The imparting of such properties is achieved by introducing an antimicrobial additive into the polymer melt. It is most expedient to introduce additives directly into the melt of the polymer composition during processing, since, for example, during the extrusion process, polymer homogenization with the additive.

Published: June 2020

A numerical study of the dynamics of pressure swing adsorption process for synthesis gas separation and hydrogen concentration was carried out. The influence of regime parameters (compressor and vacuum pump outlet pressures, duration of the "adsorption-desorption" cycle, backflow coefficient) and design parameters (height of the adsorbent bulk layer and the internal bed diameter) on the recovery and purity of hydrogen, plant performance in a given range of changes in the temperature, composition and pressure of the initial gas mixture was studied. It is found that when the hydrogen content decreases from 68 to 48 vol. % and a simultaneous increase in the carbon dioxide content in the initial gas mixture from 27 to 47 vol. % required hydrogen purity value at 99.99 vol. % can be achieved by reducing the pressure at the outlet of the vacuum pump from 0.75?105 to 0.5?105 Pa. At the same time, the duration of the adsorption stage increases from 120 to 150 seconds, and the degree of hydrogen extraction decreases from 55 to 52% due to an increase in the proportion of the flow selected for the regeneration of the adsorbent. Increasing the temperature of the initial gas mixture from 293 to 323 K leads to the need to reduce the duration of the adsorption stage from 148 to 42 s due to a decrease in the equilibrium concentrations of carbon dioxide and monoxide in the adsorbent.

One of the innovative directions of the prospective development of electric power complexes of the countries of the world is the technology of smart power supply networks, the main element of which is the system of industrial energy storage. They began to be widely used for use as local energy storage devices used in combination with renewable energy sources. The purpose of the study is to analyze the influence of the shape of the graphs of consumers' electrical loads on the effect obtained in the process of price-dependent energy management based on industrial energy storage systems in the current conditions of procurement in the wholesale and retail electricity markets of Russia. The methods of analysis, synthesis, and systems approach are used. To carry out the study, we took data on the characteristics of typical graphs of electric loads of various types of large consumers, price parameters of electricity supply from the retail electricity market, valid for consumers of the Central Federal District. Based on the three basic types of hourly electricity consumption schedules, which have different indicators of daily load factors, calculations were made of changes in the parameters of the cost of electricity purchases and average prices for the purchase of electricity, as well as the comparative characteristics of cost parameters and average prices were revealed. Based on the analysis of the parameters of the cost of electricity and average purchase prices, the example of the Voronezh region investigated the direction of change in the total cost of electricity purchases and average purchase tariffs as the fill factor of daily load schedules changes. The dependence of the effects of lowering the average price of electricity purchases on the fill factor was revealed. Based on the data on the price parameters of all electric power components for the regions of the Central Federal District, the cost parameters and average tariffs for the purchase of electricity were calculated, which made it possible to identify the uneven parameters of both the monthly costs of purchasing electricity before and after the use of electric energy storage systems, and the parameters for reducing the average purchase tariffs electricity after applying storage systems. The analysis of the effects of the use of energy storage systems for different demand schedules and levels of rated voltage was carried out, which revealed a tendency to increase the effect of a decrease in average prices for the purchase of electricity as the level of rated voltage decreases. The results can be used by employees of energy companies in Russia or energy services of industrial enterprises of the Central Federal District in the process of analysis of investment projects on the use of industrial energy storage systems.

Published: June 2020

The fishery complex is an integral part of the national economy. Fish and its processed products are an important part of a balanced and healthy diet. They do not have an alternative replacement, therefore, an efficiently functioning fishery complex plays a big role in ensuring the country's food security and preserves aquatic biological resources. In coastal areas, it is a center of labor force employment, since fishing cannot do without related industries: shipbuilding, production of gear, processing, packaging and transportation of fish products, and therefore it is the core of production and port infrastructure, an incentive for the development of the social sphere and a center attraction of innovation. Currently, the industry is experiencing difficulties associated with both internal and external problems. For further progressive development of the complex, it is necessary to attract investors and financing from various sources for the technical re-equipment of the existing material and technical base, as well as create completely new production assets. A potential investor needs information about the possible pluses and minuses, acquisitions and losses. Therefore, the purpose of this study is to analyze the potential investment attractiveness of the domestic fisheries complex. In theoretical science there is no definition of investment attractiveness. Therefore, when conducting this study, the authors followed the canons of classical economic theory and used comparison methods, historical, deduction and induction, statistical and others. Analyzing the legislation, regulatory documents, scientific articles, monographs, reviews, they came to the following conclusions: the fishery complex has an investment attractiveness under a set of certain conditions. The potential for investment attractiveness of the fishery complex at the present stage is characterized by the presence of a legislative base, increasing demand for fish in world markets and domestically, the stability of the conditions for obtaining quotas for fishing and aquatic biological resources, government participation in co-financing projects, the availability of a state order for finished products, and scientific opportunities capacity etc.

Researchers of measures of state support and regulation of small businesses in the Tyumen region. The legal basis of the mechanism of state support for small businesses in the region is represented by documents of the Federal and regional level. The infrastructure of state support for small business in the Tyumen region includes regional authorities, as well as organizations of a commercial and non-commercial nature, whose operation is aimed at promoting the implementation of small business development programs, providing assistance to small businesses and providing conditions for their creation and development. The main measures of state support in relation to small businesses include regional investment support, the region's guarantee investment Fund, providing loans, providing subsidies, microloans, and legal support for small businesses. The authors conducted a study of the system of state support for small businesses in the Tyumen region allows us to evaluate it as a fairly balanced and diverse set of measures and forms of assistance to small businesses. However, despite this, the current system of small business support needs further improvement. In this regard, the authors propose specific measures to improve state support for small businesses, which can be directly implemented in the practice of the Tyumen region, namely: the system of rating candidates for state support from the point of view of socio-economic impact of their activities designed to reduce the level of bureaucracy; the system of obtaining insider information about activity of subjects of small business, designed to increase the efficiency of the state support; the response of the system of state registers in order to exchange regional experience of measures of state support and prevention of abuses.

This economic and mathematical model is an object that also uses a system of mathematical tools that maximizes the creation of value, taking into account additional restrictions that take into account various types of innovations, which as a result make it possible to create an innovative portfolio that most closely matches the strategy of the enterprise. , price range and the necessary resource of the innovation plan. An innovative portfolio is expressed in categories of capital prices that provide “normative” returns and investment prices in various directions. The double task shows the risk of forming an optimal portfolio. The type of restrictions allows us to formulate the condition that the income should be greater than the “normative” profitability for long-term projects. Estimates for each financial indicator allow you to compare the totality of indicators, as well as conduct comparisons with planned indications. Using this economic and mathematical model, indicators are predicted that characterize the planning, management and improvement of various aspects of the economic activity of countries. In this case, it is necessary to identify general patterns. The analysis of the financial condition of the company; identified and analyzed sources of financing in a number of years; an assessment of the enterprise circulation fund has been made; the amount of payables and receivables is determined; specific ratio of individual elements.

Irkutsk region is rich in land that is suitable for agricultural activities. The total sown area of agricultural crops in the Irkutsk region is 759 thousand hectares (2019). The main place is occupied by grain and leguminous crops, the total area of which is 540 thousand hectares (71.1%). In their structure, the first place belongs to spring wheat, the second place is taken by spring barley, the third-by oats. Due to the need to strengthen the feed base, forage crops play an increasing role. Yield depends on many factors, primarily weather conditions. For photosynthesis, plant crops need sunlight. By the number of Sunny days, the Irkutsk region is not inferior to the Crimea. There are 221 Sunny days per year. If weather conditions are correctly predicted, a high yield can be achieved. To assess the absorption of solar energy by grain crops, the radiation balance was considered in this article. Photosynthetic plant pigments absorb light and convert it from solar energy to chemical energy, which results in active plant growth. To forecast the future harvest, it is necessary to calculate the intensity and duration of solar radiation, which is the most important condition for further production of agricultural products. A study was conducted on the effectiveness of using insolation in the Irkutsk region for sowing wheat. The radiation balance was compiled, which allowed us to identify the maximum solar radiation favorable for wheat growth. To determine the amount of effective radiation, measurements were made of soil temperature, air humidity, and meteorological conditions in the Irkutsk region.

The research results concerning the application of physical methods of plant raw materials influencing - fresh beetroot - to inhibit microorganisms of Salmonella genus were presented in the work. Pathogenic microorganisms of Salmonella genus pose a threat to humans, being causative agents of typhoid fever, paratyphoid fever and other salmonellosis. The use of effective and available physical methods of influence in the fruit and vegetable processing technology allows us to ensure the maximum conservation of physiologically valuable components of the raw material and its safety. Microwave (microwave field) and ultraviolet radiation were chosen as physical methods for research. The sterilizing effect of the microwave field was clearly expressed - the bacteria survival after such a treatment was 2 or more times less than during heat treatment. Treatment with ultraviolet radiation has a bactericidal effect and is characterized by a minimal effect on the plant materials organoleptic properties. A comparative assessment of the effectiveness of the inhibition of the Salmonella test culture on diced fresh beets after treatment with the selected physical methods was carried out during the study. The samples temperature rose up to 43–46 °C under the influence of a microwave field in the selected mode with a power of 400 W, a duration of 40 s, and a flux density of 0.44 W / cm2. Treatment with ultraviolet (UV) radiation in the C-band (wavelength 253.7 nm) was carried out for 15 min with a dose of 50 kJ / m2 with a total power of ultraviolet lamps equal to 60 V. Processing of fresh chopped beets with UV radiation reduced the number of microorganisms by 5 orders of magnitude from the initial amount. Processing in a microwave field allowed to reduce the initial seed contamination of raw materials by 7 orders of magnitude. Sequential processing in a microwave field and subsequent ultraviolet radiation allowed us to reduce the initial beets seedling by 8 orders of magnitude. The combination of processing methods (microwave + UV) showed the effectiveness of their application to reduce pathogenic microflora.
