DESIGN FEATURES OF GRAIN HARVESTING COMBINEERS CASE IH "AXIAL-FLOW" SERIES

Harvesting grain is a very important production process that must be carried out as quickly as possible to obtain high-quality grain. Here it is important that the equipment is adjusted to the structure of the plants, and the plants, in turn, are prepared for machine harvesting. When creating grain harvesting equipment, various factors are taken into account: agrobiological properties and the structure of plant organs, stand height and density, lowness, strength, humidity, size and weight of fruits, weight ratio of grain to non-grain part, stage of maturity and others. Currently, harvesting of grain crops is carried out by direct or separate combining. Direct involves performing several operations: cutting plants, threshing plant mass, separating grain from straw, cleaning grain from various impurities, as well as harvesting grain and non-grain part of the crop. It is important that the harvester performs these processes at the same time in the stage of full maturity of the grain. This harvesting method is suitable for bread mass that is not clogged and has ripened evenly. As for separate combining, here mowing of plants and their threshing are carried out separately. Providing the enterprise with high-performance harvesters and the level of their use significantly affect the gross harvest of agricultural crops. In case of violation of the calendar terms for harvesting grain crops by more than 10–12 days, grain losses can reach 25–30%. In order for such a situation not to arise, agricultural enterprises must have the required number of harvesters of the necessary capacity, which could ensure, in the optimal time, harvesting of agricultural crops. In order to give preference to one or another combine harvester model, you need to know not only its price, but also individual technical and economic characteristics and the cost of threshing a ton of harvest. Because this indicator reflects the cost of the harvester, operating costs, its productivity, reliability and cost of spare parts. Innovation is only accelerating. Over the past 20 years, the average productivity of self-propelled grain harvesters has increased almost four to five times. The level of computerization of mechanized operating technologies also increased. The demand for products of the grain sub-complex is only growing. Ukraine is dominated by a diverse fleet of industrial grain harvesters of foreign production, purchased both new and used, the use of these grain transport systems is expedient and relevant. The question of choosing a modern high-performance grain harvester and the question of its effective use remain relevant.

Subjective Valuation of Screening for Spinal Muscular Atrophy and Analysis of its Influencing Factors: Evidence from Iran.

Spinal muscular atrophy is an inherited neurodegenerative disorder that typically leads to severe physical disability. The present study aimed to determine the subjective evaluation of this disorder screening and analyze its influencing factors in Iran. A cross-sectional study was performed using data from the second survey of women either pregnant or planning to become pregnant in Tehran, the capital of Iran, in 2022. The dependent variable was the willingness to pay for this disease screening test. The independent variables included sociodemographic, economic, and health characteristics, the history of this disease or other diseases of the person and family, and knowledge about this disease in the included population. Logistic regression was utilized to identify independent variables associated with the dependent variable, and the results were reported as unadjusted and adjusted odds ratios and P values with 95% CIs. A questionnaire was used as a research tool, and STATA 17 software was used for data analysis. The monetary value of spinal muscular atrophy (SMA) screening was calculated by estimating willingness to pay using the congenital valuation method. In total, 578 women were included. About 64.85% of respondents had a willingness to pay for SMA screening as the dependent variable, with a mean of $526. University education (P = 0.009) and pregnancy experience (P = 0.021) were associated with the dependent variable. Iranian women expressed their willingness to undergo screening tests, but due to financial constraints, they expected the government and nongovernmental organizations to bear most of the cost.

Study on the Impact of GGDP on Carbon Peak Pathways in Beijing-Tianjin-Hebei Region

GGDP accounting, as a new green economy measurement system, can more accurately assess carbon emissions and change trends, and provide important support for the Beijing-Tianjin-Hebei region to achieve carbon peak and carbon neutrality. In this paper, the improved GGDP accounting system based on EAMFP was firstly selected according to the economic development characteristics of the Beijing-Tianjin-Hebei region, and the scale of carbon emissions and the GGDP of the Beijing-Tianjin-Hebei region from 2007 to 2021 were accounted for. The LMDI method was used to decompose the energy carbon emissions in the Beijing-Tianjin-Hebei region, and combined with the STIRPAT model to dynamically analyze the emission trend in 2022-2050, and the imbalance was found by the Mann-Kendall test. The results point out that enhanced emission reduction can enable Beijing and Tianjin to achieve carbon peak by 2030, while Hebei reaches the peak around 2040, but does not show a significant decline five years after the peak. The SVAR model confirms the correlation between GGDP and carbon emissions in the Beijing-Tianjin-Hebei region and the trend of the future impact. This paper suggests that the Beijing-Tianjin-Hebei region should learn from domestic and international experiences in carbon emission reduction and strengthen the communication and interoperability among the three regions. The Beijing-Tianjin-Hebei region has different status quo in terms of energy consumption and carbon emissions, and the policies implemented should be different.

Comprehensive Analysis of Mechanical, Economic, and Environmental Characteristics of Hybrid PE/PP Fiber-Reinforced Engineered Geopolymer Composites

Engineered Geopolymer Composites (EGCs), known for their excellent tensile properties and lower carbon emissions, have gained widespread attention in the field of fiber-reinforced concrete. However, the high cost of high-performance synthetic fibers, a crucial component of EGCs, limits their practical engineering applications. In this study, by using low-cost PP fibers hybridized with PE fibers and adjusting the fly ash/ground granulated blast furnace slag (FA/GGBS) ratio, cost-effective, high-performing hybrid PE/PP-reinforced engineered geopolymer composites (H-EGCs) were developed. This study conducted axial compressive and tensile tests on H-EGCs with different FA/GGBS ratios (7:3, 6:4, and 5:5) and PP fiber replacement ratios (0%, 25%, 50%, 75%, and 100%), investigated the influence of FA/GGBS and PP fiber replacement ratio on static mechanical behavior, and evaluated the economic and environmental benefits based on mechanical performance indicators. The result indicated that the compressive strength of H-EGCs can reach 120 MPa when the FA/GGBS ratio is 5:5; however, an increase in FA/GGBS and PP fiber replacement ratio leads to a loss in compressive strength and elastic modulus. The incorporation of PP fibers in moderate amounts enhances ultimate tensile strain by reducing crack control ability, and the maximum tensile deformation capacity (7.82–9.66%) was obtained for H-EGCs with a PP fiber replacement ratio of 50%. The optimal economic and environmental benefits of H-EGCs are observed when the FA/GGBS ratio is 5:5 and the PP fiber replacement ratio is set at 50%.

Experimental design for determining the factors influencing the filtration efficiency of solution-blown spun polylactic acid filters

Millions of people are wearing face masks because of the COVID-19 epidemic, and these masks are indiscriminately releasing pollutants into the atmosphere. One of the most appealing and promising bio-based polymers for face masks is polylactic acid (PLA). Solution-blown spinning (SBS) is a rapid and easy way to produce micro and nanofibers that may be quickly deposited on any substrate. This study aims to produce and evaluate solution-blown spun PLA fibers used as filter media. PLA nanowebs were observed for their morphology, weight, thickness, air permeability, water contact angle, and filtration properties. The average diameter of the fibers ranged between ∼163 and ∼282 nm. NaCI aerosol filtration test results showed that the filtration efficiency of these nanowebs was ≥ 94% and the pressure drop was ≤ 240 Pa, meeting requirements was assigned to the class EN 149: FFP2 particle-filtering half-maks. Filtration performance was significantly influenced by the flow rate and polymer concentration. The resulting equations for the design of experiments (DoE) regression model were examined and found to be appropriate for predicting the parameter combinations required for the desired quality factor of PLA filters. The fast and economical features of the SBS process, as well as the biodegradable nature of the PLA polymer, may considerably contribute to the development of environmentally friendly filters.

THE IMPROVEMENT OF THE ECONOMIC AND ENVIRONMENTAL CHARACTERISTICS OF COGENERATION PLANTS BASED ON HEAT ENGINES WITH THE THERMOCHEMICAL METHOD OF CLEANING THEIR EXHAUST GASES

The article presents the results of research aimed at improving the economic and environmental characteristics of cogeneration plants based on heat engines (ICE, GPE, GTU), with a thermochemical device for the neutralization of harmful components of its waste gases, and a boiler-utilizer (BU). The neutralization process takes place in a layer of red-hot carbon material and a gaseous medium, which includes: methane, hydrogen and carbon monoxide. The effectiveness of the proposed process was investigated both analytically, using specialized computer programs for energy management, and experimentally, by a special laboratory device, which made it possible to simulate in a wide range of temperatures (500...1000°C) how the products of natural gas combustion (the base fuel for the GPA and GTU), with a defined coefficient of excess air (oxygen), as well as the concentration of CO and NOx in their composition. The primary task of the experimental study was to determine the effect of temperature on the neutralization of nitrogen oxides and carbon monoxide in natural gas combustion products. The results of the studies (in the considered temperature range of 750...950℃) showed the possibility of reducing the concentration of nitrogen oxides by 2.5...3 times, and the concentration of carbon monoxide by almost 5 times. At the same time, it was established that the efficiency of NOx neutralization at the considered temperature range does not change significantly (within 10%), which makes it possible to carry out the neutralization process at a temperature of 750...780℃ and reduce the energy cost. The final neutralization of the exhaust gases of the engine and the utilization of their thermal potential is carried out in the boiler-utilizer. The placement of the thermochemical device in front of the boiler-utilizer, on the one hand, changes the thermal characteristics of the cogeneration plant to direction of increasing its heat loads, and on the other hand, increases the maneuverability of the plant, providing possibility of independent change of electrical and thermal load. In addition, the use of solid fuel with its gasification in the device allows not only to neutralize the harmful components of the engine's exhaust gases, but also to provide a partial replacement of natural gas in the engine and the boiler - utilizer with a corresponding reduction of thermal and harmful emissions in to the environment.

Dynamics of caste and early childbearing in India: a perspective of three decades

BackgroundEarly childbearing disrupts girls’ otherwise healthy growth into adulthood and adversely affects their education, livelihood, and health. Individual, sociocultural, economic, environmental, and health service-related factors contribute to childbearing among young females. In India, caste affects health outcomes despite several affirmative policies aimed at improving the health and welfare of the backward castes/tribes. However, there is a dearth of empirical evidence about the impact of caste on early childbearing, more specifically, regarding the trajectory of inter-caste disparities in early childbearing.MethodThis study used data from all five rounds of the National Family Health Survey (NFHS) in India to assess the association between caste and early childbearing over the last three decades. All women aged 20–24 [NFHS-1 (n = 17,218), NFHS-2 (n = 15,973), NFHS-3 (n = 22,807), NFHS-4 (n = 122,955) and NFHS-5 (n = 118,700)] were considered to create a pooled data set (n = 297,653) for analysis. Bivariate analysis and binary logistic regression were conducted using Stata (v17). ArcMap (v10.8) presented the caste-wise prevalence of early childbearing among the states and Union Territories (UTs).ResultsMany women continue to have early childbearing despite a considerable reduction over the last three decades from 47% in 1992-93 to 15% in 2019-21. Compared to NFHS-1, the odds of early childbearing increased by 15% in NFHS-2 and, after that, declined by 42% in NFHS-3 and 64% in NFHS-4 and NFHS-5. The inter-caste disparity in early childbearing persists, albeit with a narrowing gap, with the Scheduled castes (SC) remaining the most vulnerable group. Adjusting the effects of socio-demographic and economic characteristics, SC women had significantly higher odds of early childbearing (OR = 1.07, CI = 1.04–1.11) than those from the General caste.ConclusionTo decrease early childbirth, a focus on adolescent marriage prevention and increasing contraceptive use among young SC women is necessary. Strengthening ongoing programs and policies targeting educational and economic empowerment of the socially weaker castes/tribes will help in reducing early childbearing. Efforts to prevent early childbearing will accelerate the achievement of the Sustainable Development Goals (SDGs)-especially those related to health, poverty, nutrition, education, and general wellbeing, in addition to protecting women’s reproductive rights.

A Review of Empirical Capital Structure Research in Different Industries

The choice of capital structure is an important aspect of a firm's financial decision-making, and the differences between industries make it challenging for firms to develop a capital structure strategy. The right capital structure is critical to a firm's financial position, competitiveness, risk management, and strategic development. Existing capital structure theories provide different perspectives to understand the choice and impact of a firm's capital structure. However, the proposed assumptions are all ideal and irrational, differing significantly from the real capital market situation. By reviewing existing empirical research, this paper aims to analyze the variability of corporate capital structure choices under different industries and the influencing factors behind them. Based on the analysis of industry-specific factors affecting capital structure choices, industries are broadly categorized into three major groups: capital-intensive industries, labor-intensive industries, and innovative industries. Through case studies and empirical research on each industry, it explores how different industries' unique economic and operational characteristics shape enterprises' strategic choices in capital structure.

Assessment of the Sustainability of Productive Systems in Nariño, Colombia

Human development must ensure the welfare and survival of an ever-growing population. To assess the impact of agroecosystems on sustainability in Nariño (Colombia), variables related to sustainable development were evaluated through a semi-structured survey conducted with 122 producers from 6 municipalities in the Nariño department. The association between the categorical variables associated with the pillars of sustainability was analyzed using multiple correspondence analysis (MCA). From the MCA, 23 indicators were selected, representing quantitative information on the economic, social, and environmental characteristics of the participants. The municipalities were characterized according to the needs and strengths of the producers. Five groups encompass most characteristics of the producers, which are largely independent of geopolitical conditions. On the other hand, the population characterization indicates that the economic well-being of fruit growers can promote the conservation of natural resources. Finally, a principal component factor analysis (PCFA) was conducted to construct the General Sustainability Index (GSI). A network graph for each municipality revealed that the indicators of the production systems are in an unfavorable environment in almost all aspects related to sustainability. The GSI values reveal unstable agroecological conditions that are causing environmental deterioration, with critical levels in the municipalities of Arboleda, Sandoná, and Providencia. Social investment and public policies must be implemented to improve the economic conditions of the producers, accompanied by legislation on the proper management of natural resources.
