Spatial patterns of mortality among the able-bodied population in the Republic of Bashkortostan

BACKGROUND: Regional differentiation adds complexity to the issue of high mortality among the working-age population. The identified regional patterns of mortality causes are typically not confined to specific areas, but rather influenced by spatial factors.
 AIM: To study temporal trends in spatial patterns of mortality of the working-age population mortality from the main causes of death in the Republic of Bashkortostan. In addition, we identified territorial factors associated with the mortality patterns and trends.
 METHODS: Mortality data on 6 main causes of death from 54 municipal districts, 20 urban districts and urban settlements were collected for the period from 2002 through 2020. The analysis included estimation of the Moran's index and the spatial panel data modeling.
 RESULTS: Spatial mortality patterns were evident for mortality from diseases of the circulatory system, infectious and parasitic diseases, and external causes. The impact of crime levels in a specific region (male: p=0.046; female: p=0.019) negatively affected mortality rates from circulatory diseases among working-age men and women. Additionally, for men, the volume of gross municipal product (GMP) had an additional effect (p=0.046). Factors that contribute to a decrease in mortality from external causes among able-bodied men and women included the growth of GMP (male: p=0.010; female: p=0.003 — for women), an increase in the number of doctors per 10,000 people in the population (male: p=0.001; female: p=0.037), and the availability of nursing staff (male: p=0.026; female: p=0.005). Furthermore, crime rates had a significant impact on mortality from external causes for men (p=0.028), while the availability of hospital beds played a crucial role for women (p=0.030).
 CONCLUSION: The study provides the evidence on the presence of spatial autocorrelation in the context of causes of death, as well as common and differing factors influencing male and female mortality in Bashkortostan. The findings provide a solid foundation for further analysis of spatially determined factors contributing to mortality among working-age population.

 Originality / scientific novelty. The article provides empirical evidence of the dependence of agricultural enterprises activity indices on ICT segment enterprises development. The dependence of the results of agricultural enterprises activity on the activity of their digital solutions implementation was investigated with and without taking into account the time lag. The scientific and methodological foundations for assessing the impact of ICT on the performance of enterprises have been improved, in particular by allocating indicators for this assessment by stages of research.
 Practical value / significance. The results of the study can be used in the decision-making process regarding the digital transformation of agricultural enterprises through the implementation of ICT.

Thromboelastography-Guided Correction of Coagulopathy Before Tunneled Central Venous Access in Critically Ill Patients With Liver Disease: A Propensity Score-Matched Study.

Optimal blood product transfusion strategies before tunneled central venous catheter (CVC) placement are required in critically ill coagulopathic patients with liver disease to reduce exposure to allogeneic blood products and mitigate bleeding and thrombotic complications. This study evaluated the safety and efficacy of a thromboelastography-guided transfusion strategy for the correction of coagulopathy in patients with liver disease compared with a conventional transfusion strategy (using international normalized ratio, platelet count, and fibrinogen) before tunneled CVC insertion. A retrospective propensity score-matched single-center cohort study was conducted at a quaternary care academic medical center involving 364 patients with liver disease (cirrhosis and acute liver failure) who underwent tunneled CVC insertion in the ICU. Patients were stratified into two groups based on whether they received blood product transfusions based on a thromboelastography-guided or conventional transfusion strategy. Primary outcomes that were evaluated included the volume, units and cost of blood products (fresh frozen plasma, cryoprecipitate, and platelets) when using a thromboelastography-guided or conventional approach to blood transfusions. Secondary outcomes included the frequency of procedure-related bleeding and thrombotic complications. The total number of units/volume/cost of fresh frozen plasma (12 U/3,000 mL/$684 vs. 32 U/7,500 mL/$1,824 [p = 0.019]), cryoprecipitate (60 U/1,500 mL/$3,240 vs. 250 U/6,250 mL/$13,500 [p < 0.001]), and platelets (5 U/1,500 mL/$2,610 vs. 13 units/3,900 mL/$6,786 [p = 0.046]) transfused were significantly lower in the thromboelastography-guided transfusion group than in the conventional transfusion group. No differences in the frequency of bleeding/thrombotic events were observed between the two groups. A thromboelastography-guided transfusion strategy for correction of coagulopathy in critically ill patients with liver disease before tunneled CVC insertion, compared with a conventional transfusion strategy, reduces unnecessary exposure to allogeneic blood products and associated costs without increasing the risk for peri-procedural bleeding and thrombotic complications.

APPLICATION OF THE VIBROPNEUMATIC SEPARATOR IN THE CLEANING AND PREPARATION SECTION OF THE CEREALS PROCESSING COMPANY

The development and introduction in the milling industry of new vibrating machines for separating and drying solid particles contributes to the intensification of this difficult technological process. The vibration action allows considerably improving the kinematic parameters – increasing the acceleration and frequency of the working body, reducing the amplitude of the oscillation of the working body compared to existing machines. Cleaning the batch of grains from impurities, sorting their derived products, as well as partially reducing humidity, represent the set of operations, which are carried out with the aim of increasing the quality of the grains in the batch and the derived products. Simultaneously with the removal of impurities, cleaning reduces the volume of products that must be handled, transported and stored, as well as the removal of 1-2% of moisture along the way. In the case of wheat intended for consumption, it is aimed to eliminate impurities as much as possible, which have no food value. The modernized vibropneumatic separator intended for the processing of cereal products, contains a body, mounted on a drum, with a hermetically fixed cover, in which a telescopic connection is placed for cutting the wet product. A working organ is located inside the body, made in the form of a conical sieve with the tip up. The conical sieve is rigidly connected with a vibrating mechanism, and with the bat - by means of elastic elements. Under the action of the vibrating mechanism, the working organ performs a complex spatial movement. Ducts for exhausting the air flow are installed on the circumference of the cover. An inner cone and an outer cone are placed one inside the other under the conical sieve. The device also contains connections for the discharge of the sifted fractions and refuse.

Financial support for agricultural enterprise: indicators and performance results

The goal is to assess the results of production activities of agricultural enterprise, final financial indicators and its overall financial condition, depending on the volume of state financial support. Methods – comparison of calculated levels of dynamics of economic activity of an economic entity, abstract-logical, generalizations. Results - the state of the existing mechanism for providing budgetary funds to agricultural formations is analyzed. The trends in receiving financial assistance from the state are considered based on the use of information about their goals, strategy and competitiveness. The parameters of production of crop and livestock products at the analyzed facility over the past five years have been studied; for the same period, the volumes of funding received have been indicated, the amounts of which are not stable over the years; a direct relationship between the increase in the amount of subsidies and the increase in the volume of products produced has been substantiated. The one-sided nature of the amounts of financial investments provided, which are focused mainly on the crop production industry, is noted. The author states that despite the decrease in production indicators, there is a significant increase in gross and net profit, which helps improve the financial position of the agricultural company. Conclusions - as measures to improve the system of providing financial support to agricultural producers, it is advisable to increase public investment in agricultural enterprises in priority areas, primarily for the production of livestock food products, as well as to reduce interest rates; provide for the issuance of loans for the development of livestock farming. To ensure the sustainable functioning of an agricultural enterprise, an effective economic instrument is needed, based on a combination of state regulation and self-control, and the implementation of a balanced pricing and financial and credit policy.

Innovation and investment support for sustainable development of the agricultural sector of the economy

It is possible to ensure the country’s food security only with the sustainable development of the agricultural sector of the economy, which, in turn, is impossible without a transition to an innovative way of agricultural development. Consistent implementation of import substitution practices, improving the quality and increasing the volume of products in the long term will allow the domestic agro-industrial complex to reach a new level of its development, it is also possible only with the widespread introduction of innovative technologies and tools, thereby ensuring a high level of competitiveness of domestic agricultural products. At the same time, it is necessary to take into account the transformation of the agricultural sector of the Russian economy, which is taking place under the influence of increasing geopolitical risks, which should become a point of growth of the domestic agro-industrial complex, since, as practice shows, any economic crisis is replaced by economic growth subsequently. The aim of the study is to develop and test a methodology for determining the factors of sustainable development of the agricultural sector of the economy, based on the technology of data-mining and big-data analysis, and to conduct a subsequent assessment of trends in the identified factors.

Face contour treatment with Radiesse +: A new technique

With facial aging, lower face suffers gravitational changes due to loss of skin elasticity and bone and cartilaginous tissues remodeling. If skin excess and sagging is not high enough to justify the surgical approach, the intervention with calcium hydroxyapatite is justifiable. The article describes a technique using calcium hydroxyapatite with lidocaine (CaHA; Radiesse+, Merz North America, Inc., Raleigh, NC, USA) injection in mandibula and chin to restore facial contour that was lost in aging. This case series included men and women who underwent Radiesse+ injection in the mandible and chin at a private clinic from June 2019 to January 2022. The sagging tissues in the jowls were repositioned, starting from an access in the jowl, with vectors directed to the mandible angle and chin. The product was deposited in the subcutaneous flat, in the form of a bolus and retro injection, along the mandible and chin region. The volume of product initially used was individualized based on individual needs, but due to local edema caused on the first day, patients were reassessed after 7-15 days, in order to obtain a satisfactory result, if necessary, more volume was applied. Results: Eighty-six patients were included. Mean scores on the Global Aesthetic Improvement Scale taken by patients 3 months after treatment indicated "much improved". The procedure was well tolerated, with no adverse events. Restoring facial contour with collagen stimulation using a biostimulator such as Radiesse+, allows a natural and lasting result with a high degree of patient’s satisfaction and few adverse events.

WAYS TO STABILIZE THE CONDITION OF THE TRANSPORTATION OF AGRICULTURAL PRODUCTS IN THE CONDITIONS OF LARGE-SCALE RUSSIAN AGGRESSION

The issue of transportation of agricultural products from the producer to the buyer is important for our country. Russia's full-scale war against Ukraine emphasized the extreme importance of the transport complex for the economy and society. With the beginning of invasion of Ukrainian land, air communication with the world was completely stopped, and sea ports were also blocked. With the beginning of hostilities on the territory of Ukraine, the routes of transportation of agricultural products were disrupted, a large number of elevators were destroyed, the road surface of warehouses was destroyed, and sea ports were seized. The purpose of this article was to study the current state of freight transportation in the conditions of martial law, to improve and stabilize the ways of transporting agricultural products. The task was to find ways to improve logistics and ways to protect grain products from missile strikes, as well as possible ways to export this grain from the territory of Ukraine. The article presents the results of an analytical analysis of the state of transportation of agricultural products, suggests ways to stabilize and solve the problem. The development of logistics and cooperation with foreign partners, the construction of protected hubs for storing grain products, as well as the construction of modern elevators that could accumulate large volumes of products for their further transportation in large batches to consumers. The best option for Ukraine would be the creation of grain hubs in European countries, as well as transport grain by motor vehicle, accumulate grain in large batches, and deliver it to other parts of the world, through the ports of Europe. However, today it is not so easy, because currently European countries are imposing restrictions on the import of our grain products. Today, despite the difficult military situation, the lost part of the transport infrastructure and logistics, Ukraine is one of the largest grain exporting countries. The restoration of traditional ways of freight transportation and the constant search for new ones is a sign of a healthy and promising policy for the development of the transport industry. The European choice of our state, the support of partners will ensure uninterrupted freight transportation and will give new impetus to the development of river and railway transport.

Improved systems of material incentives for employees of mining enterprises taking into account the level of dynamic energy consumption

Methods. The theoretical and methodological basis of the research is the economic and mathematical methods of spectral analysis of the dynamics of energy consumption by units of mining and beneficiation enterprises, in particular, the mining and transport complex, crushing and beneficiation factories. The economic evaluation of the results of energy saving measures is carried out using cost analysis methods. Results. The mechanism of material incentives for employees of mining and ore enterprises has been improved based on the dependence of the level of material incentives for employees of individual units of the enterprise not only on the reduction of total electricity costs, but also on the level of the dynamic component of electric energy. This additionally allows to reduce the total costs of electricity for the production of commercial mining products ore enterprises, which is a new solution to the problem of economic stimulation of energy saving. Novelty. For the first time, a system of material incentives for employees of mining enterprises is proposed, which takes into account not only the level of performance of planned tasks in terms of volume and quality of products, but also takes into account specific electricity costs and the level of energy consumption dynamics. Practical value. The methodology and system of financial incentives for employees of individual divisions of the mining enterprise for energy saving has been developed, which takes into account the specific contribution of employees of each division of the enterprise to energy efficiency and energy saving, taking into account the level of energy consumption dynamics.

Effect of using hypotension prediction index versus conventional goal-directed haemodynamic management to reduce intraoperative hypotension in non-cardiac surgery: A randomised controlled trial

Study objectiveIt remains unclear whether it is the hypotension prediction index itself or goal-directed haemodynamic therapy that mitigates intraoperative hypotension. DesignA single centre randomised controlled trial. SettingSapporo Medical University Hospital. PatientsA total of 64 adults patients undergoing major non-cardiac surgery under general anaesthesia. InterventionsPatients were randomly assigned to either group receiving conventional goal-directed therapy (FloTrac group) or combination of the hypotension prediction index and conventional goal-directed therapy (HPI group). To investigate the independent utility of the index, the peak rates of arterial pressure and dynamic arterial elastance were not included in the treatment algorithm for the HPI group. MeasurementsThe primary outcome was the time-weighted average of the areas under the threshold. Secondary outcomes were area under the threshold, the number of hypotension events, total duration of hypotension events, mean mean arterial pressure during the hypotension period, number of hypotension events with mean arterial pressure < 50 mmHg, amounts of fluids, blood products, blood loss, and urine output, frequency and amount of vasoactive agents, concentration of haemoglobin during the monitoring period, and 30-day mortality. Main resultsThe time-weighted average of the area below the threshold was lower in the HPI group than in the control group; 0.19 mmHg (interquartile range, 0.06–0.80 mmHg) vs. 0.66 mmHg (0.28–1.67 mmHg), with a median difference of −0.41 mmHg (95% confidence interval, −0.69 to −0.10 mmHg), p = 0.005. Norepinephrine was administered to 12 (40%) and 5 (17%) patients in the HPI and FloTrac groups, respectively (p = 0.045). No significant differences were observed in the volumes of fluid and blood products between the study groups. ConclusionsThe current randomised controlled trial results suggest that using the hypotension prediction index independently lowered the cumulative amount of intraoperative hypotension during major non-cardiac surgery.

REGIONAL LABOUR PRODUCTIVITY GROWTH AND STRUCTURAL CHANGE IN TURKISH ECONOMY

Structural change is labelled as the shift of resources from low productive sectors to those with high-value-added. The structural change process can stimulate the evolution of the economy by increasing productivity. This study examines structural change and the bases of labour productivity evolution in 26 regions of Turkey for 2010-2020 period. Therefore, the Shift-Share Analysis method was employed in the study. The TURKSTAT gross domestic product in chain-linked volume, index and percentage change (2009 = 100) and employment by kind of economic activity data were utilized. The consequences revealed that the within-sector effect is the primary basis of productivity evolution in 26 regions of Turkey. The structural change has a positive but minor bearing on total labour productivity evolution in almost all regions. The within-sector effect is more dominant in the agricultural sector, but the bearing of structural change is negative. Similarly, the within-sector effect is stronger in the regions' industrial sectors (except for TR71, TRA1, TRA2, TRB2). The bearing of structural change in the services sector was better than in other sectors. As a result, it has been observed that the labour force is not directed to high-value-added sectors, particularly in the agricultural and industrial sectors, but the situation is better in the services sector.

Investigation of leaching behaviors of carbonation-cured CSA cements using an electrically accelerated leaching test

The present study provides the investigation of leaching behaviors of carbonation-cured calcium sulfoaluminate (CSA) cements with varying initial sulfate contents using an electrically accelerated leaching test. The CSA cement samples were normally or carbonation-cured for 28 days before subjecting them to an electrically accelerated leaching condition for 14 days. The samples were characterized experimentally before and after accelerated leaching. In addition, the leaching behaviors of the CSA cement samples over a wide range of cumulative leached water were thermodynamically modeled to determine their likely performance in repository environments. The results indicate that the reaction of ye'elimite was significantly promoted by accelerated leaching, resulting in the formation of ettringite after leaching, regardless of the curing regime used. Calcium sulfates and C-(A)-S-H formed in the carbonation-cured samples were the first phases to decompose upon accelerated leaching, which is in good agreement with the thermodynamic modeling calculations. For the normally cured samples, the use of higher calcium sulfate in the mixture is preferred, considering the amount of leached ions, yet the opposite holds true for the carbonation-cured samples. In particular, the changes in the calculated volumes of the reaction products upon simulated leaching were smaller for the carbonation-cured samples than for the normally cured samples.

Research on Pricing and Replenishment Strategies of Supermarket Vegetables Based on LSTM Neural Network and Goal Planning

This paper focuses on the daily replenishment volume and pricing of vegetable commodities, especially the impact of freshness on market selling price. Through Pearson correlation analysis, this study first explored the correlation between different vegetable categories and their single products and evaluated the sales correlation between each category and the single products of the same category. Secondly, this paper considers the cost-plus pricing method to analyze the relationship between the total sales volume of vegetable products and the pricing. The LSTM neural network model is used to forecast the sales volume and wholesale price of vegetable commodities, with special attention to the forecast data from July 1 to 7. Finally, this paper establishes a goal planning model with the goal of maximizing supermarket returns. Considering the total quantity of replenishment, sales volume and cost pricing as constraint conditions, the depth-first search algorithm is adopted to solve the problem, and the daily replenishment volume and pricing strategy for vegetable products in the next week are provided.

Structure Strengthening Phenomena of Gluten Matrices under Different Stress Types.

To predict the achievable product volume with respect to the gas retention capacity of the gluten matrix in wheat flour doughs, strain hardening evaluation is crucial. But assessing these structure hardening phenomena in wheat flour dough systems is still a challenging task. In this work, a simple shear method applied to kneaded dough samples was tested and compared to biaxial extension tests performed with a lubricated squeezing flow method. The comparability of shear-induced structure hardening with biaxial extension tests was shown. Structure hardening and breakdown after overload were visualized using shear flow and a comparison of the obtained shear flow over Hencky strain curve peaks. To predict the behavior of the analyzed flours according to their composition, a correlation analysis of the flour and dough properties was performed. The influence of the HMW glutenin subunits on the sensitivity of the dough matrix according to the applied shear speed (0.1 and 1.0 mm/s) could be shown with a correlation coefficient of 0.94. The LMW glutenin subunits, on the other hand, showed a high correlation coefficient of 0.89 with the achievable network connectivity parameter z [-] gained from frequency sweep testing.

Towards the implementation of hydrothermal carbonization for nutrients, carbon, and energy recovery in centralized biogas plant treating sewage sludge

In recent years, extensive experimental research on hydrothermal carbonization (HTC) of sewage sludge has been performed, to study the effects of process conditions on hydrochar characteristics and nutrient, carbon, and energy recovery from sewage sludge. To promote the implementation of HTC, this study assessed HTC (230 °C, 30 min) integration into an advanced centralized biogas plant by analyzing its theoretical effects on the fates of sewage sludge solids, nitrogen, phosphorus, and carbon. The study used the mass and nutrient flows and concentrations obtained from laboratory studies, and the studied biogas plant had an original layout that employed hygienization. HTC integration decreased the solid product volume by up to 56 % and, increased the recovery of ammonium in ammonia water by 33 % and methane by 1.4 %, while increasing the biogas plant energy demand by 4 %. The changes in the nutrient and solids flows and their recovery potentials show the need to consider the rearrangements of the liquid and gas flows in the biogas plant and the re-dimensioning of stripping process.

Automatic Pricing and Replenishment Strategy for Vegetable Products Based on XGBoost and LSTM Prediction Models

Due to the short shelf life and imbalance between supply and demand of vegetable commodities, it is important to develop reasonable replenishment and pricing strategies. This paper takes the measured data of a superstore as an example, and develops a reasonable decision-making program by studying the relationship between the information of each commodity in the vegetable category, the breakdown of the flow, the wholesale price and the recent attrition rate. First, the distribution pattern and interrelationship of the sales volume of each category and single product of vegetables are studied, and the distribution, difference and correlation between them are analyzed. Then, XGBoost is used to predict the sales volume and then LSTM is used to predict the wholesale price, to get the relationship between the total sales volume of vegetable categories and the cost-plus pricing, and for the total daily replenishment and pricing strategy in the coming week, a planning model is set up to solve the problem by using genetic algorithm. Finally, in order to maximize the revenue of the superstore, a goal planning model is established to take the sales unit price and sales volume as variables, and mathematical calculation methods are used to determine the daily sales volume and sales unit price and the maximum revenue, so as to determine the replenishment volume of a single product and the optimal pricing strategy. The proposed model fits the actual needs, is practical, efficient in calculation, and can effectively solve the proposed problem.
