Authors: Yüksel Şen , Savaş Demir Hatice
Published: August 2023

Istanbul Kadikoy–Hasanpasa Gasworks lost its function and closed in 1993, but in 2021, it was reopened for use as a culture and art center. In the transformation decisions of the gasworks, the Gasworks Environmental Volunteers, consisting of the people of the environment, have played an active role for 27 years and continue to play a role after the transformation. This study examines the impact and efforts of Gasworks Environmental Volunteers before and after the transformation and describes a collective struggle in the participatory management of heritage. The aim is to reveal the importance of public participation and non-governmental organizations in the transformation of cultural heritage structures and afterward. The study was conducted with qualitative research methods such as face-to-face interviews, observations, and literature research. As a result of the study, it has been shown that the transformation of heritage buildings, when done with the participation of the public and a human-centered conservation approach, brings positive results to the city and is sustainable when the people of the environment take part in the administration after the transformation. Society’s awareness about the heritage areas is expected to increase, and it will be a factor in the transformation decisions by protecting the heritage.
Permeable Pavement in the Northwestern United States: Pollution Source or Treatment Option?
Authors: Poor Cara , Kaye Jackson , Struck Rodney , Gonzalez Ruben
Published: August 2023

Permeable pavements can be an effective stormwater mitigation technique, but there are concerns that polluted stormwater may contaminate groundwater as stormwater infiltrates through the soil beneath the pavement. This research evaluates the pollutant removal capabilities of pervious pavements using pervious cement concrete (PC) and porous asphalt concrete (PA) cylinders. Stormwater collected from an outfall was used to perform three tests. The influent and effluent were analyzed for metals, semi-volatile organic compounds (SVOCs), phosphorus, and turbidity. Average percent removal for metals were 37–63% except for zinc, which had an average export of 21% for pervious cement concrete and 52% for porous asphalt concrete. Only 10 of the SVOCs tested had an influent concentration above detection levels. Complete removal (below detection levels) was observed for benzo(a)anthracene, benzo(a)pyrene, chrysene, and indeno(1,2,3-cd) pyrene. Average removals for benzo(b)fluoranthene, benzo(g,h,i)perlyne, fluoranthene, phenanthrene, pyrene, and bis(2-ethylhexyl)phthalate were 63–96%. No significant removal was observed for total phosphorus and reactive phosphate. All contaminant concentrations were below drinking water limits except lead, which would likely be removed in the soil layer below the pavement. This study indicates permeable pavements can effectively remove stormwater contaminants and protect groundwater as a drinking water source.
Income Inequality, Institutions, and Freedom of the Press: Potential Mechanisms and Evidence
Authors: Uzar Umut
Published: August 2023

In the last few decades, income distribution has deteriorated in a large part of the world. The inability to stop inequality has evolved into a major social crisis and has become one of the most urgent issues globally. Given the importance of the issue, identifying the root causes of inequality can be a guide for policy makers in solving the problem. Although there are a few studies linking institutional quality with income inequality in recent years, the question of whether freedom of the press affects income distribution remains unanswered. This study is the first attempt to address this question. With this motivation, the study researches the influences of institutional quality and freedom of the press on income inequality for the BRICS-T (Brazil, Russia, India, China, South Africa, and Turkey) countries for the period 1993–2016. Moreover, globalization, economic growth, and trade openness are included in the model to avoid the problem of omitted variable bias in explaining inequality. The study findings indicate that institutional quality and freedom of press, which are the main independent variables for the entire panel, reduce inequality. In addition, although trade openness is a factor that reduces inequality, globalization and economic growth are not statistically significant. Although the country-specific estimates show heterogeneity, they are quite promising in terms of inequality, institutional quality, and freedom of the press. In this framework, policy makers can reduce inequalities by designing policies that emphasize institutional quality and freedom of the press. With such a win-win opportunity, BRICS-T countries can achieve two important gains to reach developed country status.

Published: August 2023

The main aim of this research was to shed light on the influence of social media campaigns on consumers’ attitudes toward green tourism, aligning with sustainable consumer behavior. However, the prior literature explored the campaign characteristics and perceived usefulness of attitudes toward green consumption that translate into green consumer behavior. Data were collected from four hundred social media users, and the confirmatory factor was used to measure their reliability and validity. Hypotheses were measured through structural equation modeling. This research suggested that managers should consider campaign characteristics such as informativeness and persuasiveness to develop positive attitudes toward green tourism. Moreover, researchers should focus on social media campaign characteristics and perceived usefulness as antecedents of consumers’ attitudes toward green tourism.
Less Is More: Seagrass Restoration Success Using Less Vegetation per Area
Authors: Mourato Carolina V. , Padrão Nuno , Serrão Ester A. , Paulo Diogo
Published: August 2023

Seagrass restoration in open coast environments presents unique challenges. Traditional sod transplant designs, though relatively successful in these environments, are impractical for large-scale restoration due to high biomass requirements. Here, we develop the checkers design, which aims to optimise the usage of biomass by transplanting fewer sods in a checkerboard pattern. We established six plots (9 m2 each) for each species (Zostera marina and Zostera noltei), with 25 sods in each plot. The area, percent cover, density, and leaf length were measured at 1, 6, and 12 months. The plots located on the seaward end of the transplant design vanished over the winter, suggesting location-dependent survival influenced by winter storms. Nevertheless, both species exhibited increased percentages of cover, density, and vegetated area after one year, with variations between species. Z. noltei showed a slower expansion but greater resilience to winter, while Z. marina displayed a higher density and cover over the first 6 months but experienced area loss during the winter. Despite these differences, both species survived and increased vegetated areas after one year, indicating the viability and promise of the checkers method for large-scale restoration. However, careful consideration of location or storm-mitigating measures is essential for the successful implementation of this method.
Associations of Positive and Negative Perceptions of Outdoor Artificial Light at Night with Nighttime Outdoor Behaviors and Health: Self-Reported Data Analyses on Urban and Suburban Residents in Japan
Authors: Wang Tongyu , Kaida Naoko , Kaida Kosuke
Published: August 2023

Nighttime light guarantees outdoor work, leisure, and other activities, and its convenience and security greatly improve the quality of human life. However, the negative effects of outdoor artificial light at night (ALAN) on humans are also being proven. This study aimed to examine the relationships between outdoor nighttime lighting and human behaviors (i.e., outdoor nighttime behaviors such as jogging and meeting friends) and health (i.e., physical and mental health, including sleep quality and stress) through how individuals feel about outdoor ALAN (i.e., ALAN perceptions) in their living environment. Two online questionnaire surveys were conducted among residents of Tokyo (Survey 1, N = 2000) and Tsukuba City (Survey 2, N = 500), Japan. Structural equation modeling results show that both positive and negative ALAN perceptions increase nighttime outdoor behavior in both surveys. In Survey 1, this association led to a deterioration in sleep quality and physical and mental health. The current findings contribute to understanding the controversial relationships between the pros and cons of nighttime light perceptions and behaviors and health. They also contribute to designing better nighttime lighting in outdoor public and private spaces with relevant restrictions by balancing the benefits and harms of outdoor ALAN.

Published: August 2023

This study presents a systemic and causal model of integrated stakeholder risk management of industrial facilities under sustainable development conditions. This model allows us to analyze the main factors of stakeholder influence, namely personnel risks, conflicts, and behavioral economic factors on a scientific project. This method is based on the identification of stakeholders and determining the possibility of the presence in their activities or inaction of personnel risks, conflicts, and behavioral economic factors that can affect the success of the production of industrial facilities, as well as on the calculation of toxicity indicators for each stakeholder. This study presents information technologies for the integrated management of industrial facilities in the context of sustainable development and transition to a circular economy, which, under conditions of uncertainty, allow the manager of an industrial enterprise and his team to implement the methodology of integrated management of industrial facilities in the context of sustainable development and transition to a circular economy to ensure the successful and timely implementation of these projects to meet the needs of stakeholders.
Solar Panel Cooling System Evaluation: Visual PROMETHEE Multi-Criteria Decision-Making Approach
Authors: Rehman Ateekh Ur
Published: August 2023

The energy sector is interested in sustainable solar power plants. It is obvious that the working temperature of solar panels, which is significantly higher than the specified working cell temperature in hot climes, has a significant impact on efficiency and longevity. The selection of solar panel cooling systems, on the other hand, is worrisome since the choice process incorporates ergonomic, technical, economic, and environmental issues. The goal of this research is to (1) present a multi-criteria decision-making approach that is both quantitative and qualitative in nature for selecting solar panel cooling systems; (2) outrank nine alternative solar panel cooling systems with eleven performance measures for each alternative to assist decision makers in determining the best viable choice; and (3) visualize the relationship between the different solar panel cooling systems and performance measures under consideration. The proposed approach is to compare and rank solar panel cooling systems, as well as their validation and evaluation through sensitivity analysis. When operating efficiency is prioritized, finned air cooling is shown to be the best solar panel cooling technique, whereas thermosiphon cooling is the best alternative when emission reduction criteria are prioritized. A comparison of the findings shows that phase change material cooling and forced convection cooling performed worst in almost all cases.
Coupling Computational Fluid Dynamics and EnergyPlus to Optimize Energy Consumption and Comfort in Air Column Ventilation at a Tall High-Speed Rail Station
Authors: Wang Haitao , Lu Ning , Wu Fanghao , Zhai Jianfeng
Published: August 2023

With the rapid development of railways, the air distribution and thermal comfort within waiting halls of high-speed railway stations receive significant attention. In this research, the EnergyPlus and CFD simulation coupling method was employed to investigate three ventilation schemes (column attached ventilation (CAV), side jet ventilation (SJV), column attached with side jet ventilation (CASJV)) for the waiting hall of a high-speed railway station in Guangzhou. The research focused on analyzing the airflow characteristics, thermal comfort, and cooling energy consumption associated with each ventilation method. The results show that thermal stratification phenomena are obvious in summer waiting halls. Most of the predicted mean vote (PMV) values in the research are from −0.5 to 0.5, indicating a comfortable thermal environment. In certain areas of both the CAV and SJV, the LPD1 > 40%, which may lead to a strong sensation of a cold draft for passengers. Compared with the SJV, the CAV and CASJV save 11.89% and 9.25% in cooling energy consumption, respectively. Therefore, the CASJV is more suitable for applications in high-speed railway station waiting halls. The results of this study aim to support the application of this combination of attached ventilation and an “air column” air supply in high-speed railway stations.
Global Discontinuity: Time for a Paradigm Shift in Global Scenario Analysis
Authors: Rothman Dale S. , Raskin Paul , Kok Kasper , Robinson John , Jäger Jill , Hughes Barry , Sutton Paul C.
Published: August 2023

The evolutionary paths of social-ecological systems comprise periods of structural continuity punctuated by moments of convulsive change. Various forms of systemic global shock could materialize in the coming decades, triggered by the climate crisis, social disruption, economic breakdown, financial collapse, nuclear conflict, or pandemics. The unfolding COVID-19 pandemic stands as a real-time example of an interruption of historic continuity. More hopefully, deep institutional and cultural shifts could rapidly usher in more resilient forms of global civilization. These plausible possibilities challenge scenario studies to spotlight discontinuous futures, an imperative that has not been adequately met. Several factors—for example, gradualist theories of change, scientific reticence, the lure of quantitative tractability, embeddedness in policymaking processes—have rendered mainstream scenario analysis ill-suited to the task. The emphasis on continuity fails to alert decision makers and the public to the risks and opportunities latent in our singular historical moment. A shift to a paradigm that foregrounds discontinuity is long overdue, calling for efforts to broaden the base of persons involved; devote more attention to balancing narrative storytelling and a broader range of quantitative methods; and apply and develop methods to explicitly consider discontinuities in global scenario development.

Published: August 2023

Technological infrastructure plays a critical role in a country’s development and progress, enabling economic growth, innovation, and improving citizens’ quality of life. This study explores the potential of digital entrepreneurship and digital transformation in reducing unemployment in Oman. With the increasing reliance on digital technologies, governments need to invest in technological infrastructure that can meet the evolving needs of society. This study investigates the potential of digital entrepreneurship and digital transformation in reducing unemployment in Oman. This study highlights the importance of technological infrastructure in enabling economic growth and improving citizens’ quality of life. The findings indicate that digital entrepreneurship offers equal opportunities for both genders, potentially empowering women in entrepreneurship and addressing unemployment challenges. Additionally, the study shows a positive relationship between age and digital entrepreneurship aspirations. To foster entrepreneurship, the study suggests empowering young job seekers with digital knowledge and enabling graduates to create new opportunities for businesses and entrepreneurs. The study found significant effects of “Unemployment in the Sultanate of Oman (reasons and solutions)” on occupation, as indicated by a between-group sum of squares of 8.773, two degrees of freedom, and a mean square of 4.387, with an F value of 11.274, and a significance level of 0.000. On the other hand, the “Digital Entrepreneurship Sector” significantly affected occupation, with a between-groups sum of squares of 4.394, two degrees of freedom, and a mean square of 2.197, and an F value of 10.267 with a significance level of 0.000. Similarly, for the “Entrepreneurship Digital Infrastructure” variable, there was no significant difference between male and female mean scores (t = −1.516, df = 206, p = 0.131). Overall, the results indicate that the digital entrepreneurship sector significantly impacts occupation, while the entrepreneurship digital infrastructure has no significant effect. Additionally, female respondents showed a higher mean score in perceptions of “Unemployment in the Sultanate of Oman (reasons and solutions)” compared to male respondents.

Authors: Vlachogianni Prokopia , Tselios Nikolaos
Published: August 2023

Given that educational technology has increased tremendously, usability testing is a necessity to maximize the efficiency of technological tools in education. The findings of a systematic review including 42 research papers that evaluated the educational technologies’ perceived usability with the Post-Study System Usability Questionnaire (PSSUQ) and the Computer System Usability Questionnaire (CSUQ) are presented in this article. The results were categorized according to the following factors: (a) score derived from evaluating usability with PSSUQ/CSUQ, (b) type of educational technology employed, (c) subject studied, (d) educational stage, (e) participant type, (f) age, and (g) participant count in each survey. The usability levels were found to be satisfactory (M = 72.75, SD = 15.12) from the statistical analysis of all surveys (N = 58). The mobile applications category showed a very good mean PSSUQ/CSUQ score (M = 81.53, SD = 12.61) followed by the multimedia category with 73.89 (SD = 19.69) and internet platforms (M = 73.23, SD = 7.74). The educational stage (p = 0.01) and the participant type (p = 0.005) seem to relate to the obtained PSSUQ/CSUQ scores. However, the participants’ age, the subject being studied, or the participant count in each study did not exhibit any significant correlation with the PSSUQ/CSUQ scores. Over the course of time, a marginal non-statistically significant improvement was noted in terms of perceived usability (p = 0.136).

Published: August 2023

The current work aimed to study nanomodified HPC with multi-walled carbon nanotubes (MWCNT). The effect of MWCNT concentration, from 0% to 0.6% of cement weight, was evaluated on HPC multi-level output properties, namely, the flowability, mechanical strength, electrical resistivity, and microstructure. In addition, a tentative, simplified, and more cost-effective method based on dispersion of a high-pH solution of hydroxide was also adapted to disperse the MWCNT before incorporation in fresh HPC mixtures. Adding 0.2–0.6% MWCNT reduced HPC workability even with a higher superplasticiser dosage. The electrical resistivity was 484.58 Ω m for the HPC without MWCNT at 28 days of curing, while the samples with 0.2%, 0.4%, and 0.6% MWCNT presented 341.41 Ω m, 363.44 Ω m, and 360.34 Ω m, respectively. The use of 0.2–0.6% MWCNT in HPC decreased the flexural and compressive strength by 20% and 30%, respectively. The HPC performance decrease with MWCNT seemed to be related to relatively significant agglomerations of the long MWCNTs, namely, in HPC-0.6% samples. New developments are needed to state a simple and cost-effective dispersion method for MWCNT incorporation in HPC. In addition, smaller dosages of MWCNT are suggested for future research works.

Published: August 2023

The nucleon-pair shell model (NPSM) within the framework of a broken symmetry basis is studied. The results demonstrate the validity of such a scheme, which in turn leads to a significant reduction in the dimensionality of the multi-pair configuration space. Specifically, in the case of an axially-deformed basis, the results yield a satisfactory description of the low-lying spectrum, even without the need for applying the projection procedure. In the case of a triaxially-deformed basis, the result of variation after angular momentum projection suggest a potential for using the NPSM to find exact solutions in a semi-magic system.

Published: August 2023

Synergistic interaction between cavitation bubbles and particles is critical for the operational performance of hydro turbines. The jet dynamics near the wall have been extensively investigated; however, the jet dynamics near the particles are not clear. In the present paper, the bubble jet dynamics near a spherical particle are numerically investigated based on a compressible two-phase flow solver considering the effects of heat transfer and mass transfer between the phases. Furthermore, the effect of the distance between the particle and the initial position of the bubble on the jet characteristics is analyzed in detail. Based on the simulations, three typical cases (i.e., jet during the rebound stage, jet pointing towards the particle, two jets facing each other) of jet behavior are categorized together with the range of dimensionless parameters. As the distance between the particle and the bubble increases, the three cases of jet impacts occur in the rebound stage, in the first period, and in the transition from the first period to the rebound stage, respectively.

We reviewed the multiplex PCR results of 20,127 respiratory specimens tested in a hospital setting from January 2014 to April 2023. The seasonal oscillation patterns of 17 respiratory viruses were studied. Compared with 2014–2019, a prominent drop in PCR positivity (from 64.46–69.21% to 17.29–29.89%, p < 0.001) and virus diversity was observed during the COVID-19 pandemic, with predominance of rhinovirus/enterovirus, sporadic spikes of parainfluenza viruses 3 and 4, respiratory syncytial virus and SARS-CoV-2, and rare detection of influenza viruses, metapneumovirus, adenovirus and coronaviruses. The suppressed viruses appeared to regain activity from the fourth quarter of 2022 when pandemic interventions had been gradually relaxed in Hong Kong. With the co-circulation of SARS-CoV-2 and seasonal respiratory viruses, surveillance of their activity and an in-depth understanding of the clinical outcomes will provide valuable insights for improved public health measures and reducing disease burden.

Published: August 2023

Continuous groundwater quality monitoring is crucial for ensuring safe drinking and irrigation by mitigating risks from geochemical contaminants through appropriate treatment methods. Therefore, the primary objective of this study was to assess the suitability of groundwater collected from Lucknow, India, for both drinking and irrigation. Forty samples were collected from different sites within the study area to evaluate groundwater quality. Various parameters such as pH, turbidity, total dissolved solids (TDS), chlorides (Cl−), total alkalinity, total hardness, sulphate (SO42−), nitrate (NO3−), fluorides (F−), iron (Fe), arsenic (As), magnesium (Mg2+), and calcium (Ca2+) were analyzed. The weighted arithmetic water quality index (WAWQI), a vital rating system representing overall water quality, was employed to classify the water into different categories, such as very good, good, moderate, poor, and unfit for drinking. This classification is invaluable for public awareness and decision-making to make informed decisions regarding effective management, treatment, and sustainable societal development on a broader scale. A correlation matrix was generated and analyzed to observe correlations between the various parameters. Additionally, spatial distribution maps for the analyzed parameters and WQI were prepared using the inverse distance weighted (IDW) method. The study found that WQI values in the area ranged from 2.64 to 168.68, indicating good water quality in most places except for the Kukrail region, where the water quality is unfit for drinking purposes. The water quality map shows that 86% of the area falls under the very good category, 14.63% under good to moderate quality, and 0.37% is categorized as unfit for drinking. Consequently, the findings suggest that the groundwater in the studied area is safe and suitable for drinking and irrigation purposes.
Influence of High-Frequency, Low-Voltage Alternating Electric Fields on Biofilm Development Processes of Escherichia coli and Pseudomonas aeruginosa
Authors: Kunlasubpreedee Patthranit , Tobino Tomohiro , Nakajima Fumiyuki
Published: August 2023

A non-chemical solution is needed to control biofilms in water and wastewater treatment systems. High-frequency alternating electric field application offers an alternative approach that does not involve undesired electrode surface reactions. However, the effect of high-frequency alternating electric fields on bacterial cells in the attached-growth mode remains unexplored. This study investigated the impact of such fields on two stages of the biofilm development process: the initial adhesion phase (stage 1) and the early development phase (stage 2). Experiments were conducted using Escherichia coli and Pseudomonas aeruginosa in a three-channel flow cell exposed to alternating electric fields (3.05 V/cm, 20 MHz). The primary outcome of this study demonstrated that alternating electric fields decreased adhered cell numbers at both stages due to their inhibitory effect on growth. The alternating electric fields also triggered cell detachment after the initial attachment stage but not in mature biofilms. Interestingly, despite a reduction in cell counts, the amount of total biofilm biomass remained unaffected, which was likely due to increased cell size via cell elongation compensating for the decrease in numbers. No synergistic effects with respect to hydrodynamic forces were observed. These findings highlight the potential applicability of alternating electric fields to biofilm control and provide implications for water and wastewater engineering applications.

This modeling study intended to solve a part of the global scientific problem related to increased concentrations of carbon dioxide in the atmosphere via emissions from terrestrial ecosystems that, along with anthropogenic emissions, make notable contributions to the processes of climate change on the planet. The main stream of CO2 from natural terrestrial ecosystems is related to the activation of biological processes, such as the production/destruction of plant biomass. In this study, the Wetland-DNDC computer simulation model with a focus on nitrogen and carbon biogeochemical cycles was used to study the effect of hydrothermal conditions on greenhouse gas fluxes in West Siberian peatlands. The study was implemented on the site of the world’s largest pristine wetland/peatland system, the Great Vasyugan Mire (GVM). The study was carried out based on data from permanent measurements at meteo stations and our own in situ measurements of hydrological and thermal parameters on sites, which allowed for testing different scenarios of changes in environmental conditions (temperature, precipitation, groundwater level) together with a change in GHG fluxes. The study revealed the air temperature and the level of groundwater as the main drivers controlling CO2 fluxes. The study of different scenarios of change in annual air temperature revealed the threshold of change in the wetland/peatland ecosystem from carbon sink to carbon source to the atmosphere to happen with an increase in the average annual air temperature by 3 °C with reference to the average annual air temperature values in 2019. Also, we found that the wetland/peatland ecosystem turned to act as an active carbon sink with about 7 cm increase in annual groundwater level, compared with its base level of −21 cm.

Published: August 2023

This study aims to investigate hydrogeochemical characteristics and groundwater quality in the Hebei Plain and to discuss factors controlling the groundwater quality. A total of 54 groundwater samples were collected and analyzed for 31 hydrogeochemical parameters, and a fuzzy synthetic evaluation (FSE) method was used for assessing groundwater quality. Results show groundwater total hardness, total dissolved solids (TDS), and major ions excluding K+ in phreatic aquifers higher than that in confined aquifers. From the Piedmont plain to the littoral plain, phreatic aquifers towards the reducing environment, and the enhancement of water–rock interaction, ion exchange process, and evaporation probably resulted in the increase in groundwater TDS, major ions (excluding HCO3− and SO42−), B, and Mn concentrations. Moreover, phreatic groundwater chemistry was mainly controlled by rock weathering changing into evaporite dissolution and seawater intrusion from the Piedmont plain to the littoral plain, according to the Gibbs diagram. The proportion of drinkable groundwater in confined aquifers was 1.6 times that in phreatic aquifers. In phreatic aquifers, the proportion of drinkable groundwater in the Piedmont plain was as high as 68%, but none of the drinkable groundwater occurred in the central and littoral plains. Groundwater quality in phreatic aquifers was mainly controlled by five factors, including the water–rock interaction, the marine geogenic sources, the agricultural pollution, the acidification, and the reductive environment. By contrast, groundwater quality in confined aquifers was mainly controlled by three factors, including the water–rock interaction and redox processes, agricultural pollution, and the input of external water. Therefore, in the Hebei Plain, groundwater in confined aquifers is more suitable for drinking purposes than in phreatic aquifers. Additionally, phreatic groundwater in the Piedmont plain should be protected.

Oral health is essential during oral sex, and poor oral health can increase the risk of transmitting infections and pathogens. Infections can be transmitted through contact with seminal fluid, vaginal secretions, anal secretions, saliva, and other bodily fluids. The use of condoms or female condoms during oral sex can reduce the risk of STI transmission, especially through contact with semen or vaginal secretions. Gentle barriers such as latex female condoms, plastic films, or dental dams can also be used to protect mucoumembranes from direct contact with a partner. In addition to protective equipment, maintaining oral health, regular dental visits, and being careful with oral contact if there are injuries, sores, or lesions in the mouth can reduce the risk of transmitting infections. Education and information about safer sex practices are also important in helping people make informed decisions and take care of their sexual health.

Одним из условий повышения эффективности производства молока, уменьшения затрат и улучшения условий труда для животноводов является модернизация ферм с внедрением технологий беспривязного содержания и обслуживания скота. Благодаря программе субсидирования кредитов, активно ведутся реконструкция старых и строительство новых молочных ферм во всех регионах страны. Наличие проектной документации, прошедшей экспертизу, является одним из условий субсидирования. При ее разработке, как для реконструкции старых, так и для строительства новых ферм и комплексов, проектировщики обязаны соблюдать действующие в стране нормативы, изложенные в рекомендациях, правилах и др. Данные документы можно разделить на технологические, строительные, экологические, зоотехнические и ветеринарные. Основными из них, регламентирующими требования к разделу проектной документации «Технологические решения», являются РД-АПК 1.10.01.01-18 «Методические рекомендации по технологическому проектированию ферм и комплексов крупного рогатого скота» и Приказ Министерства сельского хозяйства РФ от 21 октября 2020 г. № 622 «Об утверждении ветеринарных правил содержания крупного рогатого скота в целях его воспроизводства, выращивания и реализации». Анализ нормативных параметров в приведенных выше документах выявил несоответствие их требованиям современных ферм, что показывает необходимость их корректировки на основе проведения научных исследований и опыта эксплуатации новых ферм.

A prerequisite for advancing the milk production efficiency, lowering the costs, and improving the work environment of farm personnel is to upgrade the farms through introducing the free-stall cattle housing and caring. Owing to the state subsidy program, an active reconstruction of old dairy farms and construction of new ones is in progress in all country regions. The available design documentation having passed the expert examination is important to receive a subsidy. When developing the design documentation for construction/ reconstruction of cattle farms, the designers must follow the valid national standards as set out in the recommendations, rules, and other documents. The latter may be classified into technological, construction, environmental, zootechnical, and veterinary ones. Two major documents govern the requirements of the “Technological solutions” section within the design documentation. They are the Management Directive for Agro-Industrial Complex RD-APK 1.10.01.01-18 “Recommended Practice for Engineering Designing of Cattle Farms and Complexes” and the Order of the Agriculture Ministry of the Russian Federation of October 21, 2020 N 622 “On approval of veterinary rules for cattle housing for its reproduction, growing and marketing.” The close consideration of norms specified in the above documents revealed their inconsistency with the modern farm requirements. This proved the need for revision and corrections based on relevant research and operating experience of new farms.
