Effect of replacing dietary maize with millet on production performance of laying birds

The study was conducted to determine the effect of replacing dietary maize with millet on production performance of laying birds. The study was conducted between May and August 2018 at the Poultry Production Unit of Sokoto State Veterinary Center, Aliyu Jodi Road, Sokoto. Two hundred and forty black Bovan Nera layers of 23 weeks of age (averaging 1.3 kg live weight) were used in a completely randomized designed to evaluate the performance of laying chickens fed diets containing different levels of protein. Eggs were collected in the evening (5.00 – 6.00 pm). Egg weight was monitored on weekly basis. Feed intake, number of eggs, minimum and maximum temperatures of the pen and mortality were recorded on daily basis. The data was subjected to analysis of variance (ANOVA), using Statview Analytical Computer Package. There were no significant differences in feed intake between the treatments (p>0.05) even though birds on the millet-based diets consumed slightly higher amount of feed (100 – 102 g/b/d) compared to those on the maize-based diet (99 g/b/d). Hen – day egg production was similar between the treatments (59 – 61%). Egg weight was also not significantly (p>0.05) affected by the dietary treatments (46 – 48 g). The study concludes that egg mass decrease when maize is replaced with dietary millet.

Improvements and Challenges in StarCraft II Macro-Management A Study on the MSC Dataset

Macro-management is a crucial aspect of real-time strategy (RTS) games like StarCraft II, which involves high-level decision-making processes such as resource allocation, unit production, and technology development. The MSC dataset, as presented in the original paper, provided an initial platform for researchers to investigate macro-management tasks using deep learning models. However, there are limitations to the dataset and existing baseline models that call for improvement. In this paper, we discuss the challenges and opportunities in enhancing macro-management research in StarCraft II. We propose improvements to the dataset by incorporating new features, addressing data imbalance, and updating preprocessing techniques. Furthermore, we review recent research and state-of-the-art methods in RTS games, such as attention mechanisms, graph neural networks, and reinforcement learning, that could be applied to improve existing tasks or introduce new research directions. We also present our experimental results, highlighting the effectiveness of the proposed improvements and novel approaches. Our goal is to inspire the research community to explore advanced AI techniques and strategies in macro-management and contribute to the development of more capable AI agents in complex RTS games.

Effect of Adenosine 5´ Triphosphate (ATP) and Incubation Time on Frozen Thawed Buffalo Bull Spermatozoa

The present study was aimed to determine the effect of ATP dose rate on longevity, motility, and viability of frozen-thawed buffalo bull’s sperm. For this purpose, 20 frozen semen straws of four different buffalo bulls were obtained from a private semen production unit (Al-Hiawan Sires, Sahiwal). The experiment was replicated four times. In each replicate, four frozen straws of the same bulls were thawed and pooled. After evaluating the motility, the pooled frozen-thawed sample was aliquoted into three separate tubes containing 0 (control), 1-, or 2-mM concentrations of ATP. Afterward, each aliquot was incubated at 37oC for 4 hrs. The sperm motility, viability, and membrane integrity were observed at various time points (10 min., 1hr, 2hr, and 4hr) during the incubation period of four hrs. It was observed that progressive motility and most of the motion kinematic parameters were greater (P<0.05) in control. A significant (P<0.05) interaction was observed between ATP dose and incubation time. The progressive motility, total motility, VCL, VAP, ALH, and BCF decreased (P<0.05) both by incorporation of ATP (1mM or 2mM) and increasing incubation time (from 10 min to 4hrs) which indicate the ATP and incubation time of 4 hours negatively affect the motion kinetics of buffalo bull sperm. In conclusion, it was witnessed that the motility and plasma membrane integrity of sperm declined by the supplementation of ATP in frozen-thawed buffalo bull semen.

Evaluation of Technical and Economic Indicators for the Production Process of Microalgae Lipids Considering CO2 Capture of a Thermoelectric Plant and Use of Piggery Wastewater

Microalgae are highly studied microorganisms for the production of high-value products due to their high content of proteins, lipids, carbohydrates, and chlorophyll. These compounds are refined to obtain profitable industrial products. This article analyzes the lipid production of Chlorella sp. biomass, considering 18 scenarios for its production, with 9 of these being partially supplemented with swine wastewater. A 1 ha area was considered for biomass cultivation, primary and secondary biomass harvesting, and lipid extraction. Using simulation in the software SuperPro Designer v10, parameters such as CO2 capture (from a thermoelectric power plant), freshwater consumption, wastewater consumption, energy consumption, and unit production cost were evaluated. The results show that the production cost is high, ranging from 836.9 US $/kg to 1131.5 US $/kg of produced lipids, with a maximum CO2 capture of 454 kg of CO2/kg of lipids. The use of wastewater reduces the production cost by approximately 10%. The evaluation of technical and economic parameters allows us to identify bottlenecks and implement strategies to reduce production costs.

Challenges of ecocentric sustainable development in agriculture with special regard to the internet of things (IoT), an ICT perspective

Abstract“Feed the global population and regenerate the planet.”The conditions necessary for the implementation of the above commonly used slogan did not exist 10–15 years ago. We did not have access to the information and databases that would have allowed us to increase yields for the purpose of feeding the growing population. While increasingly meeting sustainability requirements and regenerating the Earth. Anthropocentrism, the belief that humans are superior to everything else, benefits humans by exploiting human greed and ignorance, which is a dead end for both individuals and societies. Only humans can ignore the dynamic equilibrium processes of nature and disregard the consequences that adversely affect future generations. Ecocentric agricultural practices have several prerequisites. It is important for the academic sphere to recognize its significance. Another fundamental challenge is the continuous monitoring of the production unit and its close and distant environment for the purpose of decision preparation using Big Data. The Internet of Things (IoT) is a global infrastructure that represents the network of physical (sensors) and virtual (reality) “things” through interoperable communication protocols. This allows devices to connect and communicate using cloud computing and artificial intelligence, contributing to the integrated optimization of the production system and its environment, considering ecocentric perspectives. This brings us closer to the self-decision-making capability of artificial intelligence, the practice of machine-to-machine (M2M) interaction, where human involvement in decision-making is increasingly marginalized. The IoT enables the fusion of information provided by deployed wireless sensors, data-gathering mobile robots, drones, and satellites to explore complex ecological relationships in local and global dimensions. Its significance lies, for example, in the prediction of plant protection. The paper introduces small smart data logger robots, including the Unmanned Ground Vehicles (robots) developed by the research team. These can replace sensors deployed in the Wireless Sensor Net (WSN).

Анализ эколого-экономической эффективности функционирования регионов Приволжского федерального округа

The article presents a comparative analysis of the ecological and economic efficiency of the functioning of the natural, social and production systems (NSPS) of the Volga Federal District in the context of its constituent regions. The study is based on the calculation of specific indicators of the environmental intensity of the subjects of the Russian Federation, taking into account three interrelated factors of the functioning of the systems: territorial (extent, area of the subject); social (population); economic (economic resources and opportunities of the region). Thus, in the course of the study, the indicators of environmental intensity were calculated depending on the area of the subject of the Russian Federation, its population and the gross regional product. The article presents a comparative characteristic of the regions of the Volga Federal District according to these indicators, the main conclusions concerning the ecological and economic efficiency of the NSPS of the Volga Federal District are made. The study showed significant differences in the ecological and economic efficiency of the functioning of the NSPS of the regions that make up the Volga Federal District, which indicates significant imbalances in their development. The Republic of Tatarstan has one of the worst indicators of specific emissions in the territorial aspect, but occupies a leading position in terms of specific emissions per unit of gross regional product. In other words, in the Republic much attention is paid to the issues of environmental efficiency of production. The Kirov region can be characterized as a region with a low level of environmental and economic efficiency of the functioning of the NSPS, therefore, in the strategic planning of the territory, special attention should be paid to the introduction of modern low-waste and waste-free production technologies.

Electric vehicle battery-charging service and operations managing under different charging station construction modes

Using electric vehicles (EVs) is considered as an effective way to reduce carbon emissions. In practice, (self) charging-mode EVs (CEVs) require a long charging time, which has led to the emergence of (battery) swapping-mode EVs (SEVs). This study first discusses whether the manufacturer should introduce SEVs and identifies the introduction conditions. Further, it investigates the impact of two construction modes (manufacturer-construction mode and commission-construction mode) of energy replenishment stations on pricing decisions, EVs demand, and profits. Finally, we optimize the government subsidy level to minimize the total capital expenditure for a specific EVs adoption target. The results reveal that introducing SEVs can bring more stations, higher retail price and charging service fee for CEVs, as well as greater demand for EVs when the unit production cost of CEVs is high. If the consumers’ preference for SEVs is low, introducing SEVs can increase profits in most cases; if the consumers’ preference for SEVs is high, introducing SEVs is detrimental to the EVs manufacturer only when the government subsidy is not too high. Comparing to the commission-construction mode, the manufacturer-construction mode can bring more stations, higher total demand for EVs, and higher total profits; meanwhile, it can lower the optimal subsidy level of the government.

Revolutionizing the Major Threat Challenges in Pharmaceutical Industries by Monitoring Heating, Ventilation and Air Conditioning Systems

The environmental as well as personal individuals are mainly influenced by the air ventilation. In pharmaceutical industry the efficacy of substances including raw materials, in-process ingredients, finished products and machineries in the pharmaceutical manufacturing industry is mainly influenced by the air ventilation quality in interior area of the industry. Heating, ventilation and airconditioning system plays a vital role in ensuring the quality pharmaceutical drug substances as well as drug products. It also protects the pharmaceutical products from contamination and cross contamination from various contaminants like dust or dirt particles and environmental other microorganisms. HVAC system design impacts the architectural design layout of the building as these sequentially have an influence on the room pressure, pressure cascades, pressure differentials, contamination and cross-contamination control. So, the design of the system must be considered carefully at the primary design period of the pharmaceutical industrial plant.It also controls a variety of operating functions which are involved in regulating the acceptance criteria, quality assurance, validation and qualification of the building facility, operational documents and the documentation for maintenance.

These novel findings redefine the landscape of integrated solar membrane distillation and pave the way for more sustainable and economically viable water desalination solutions.

Numerical simulation of heat transfer performance of spiral wound heat exchanger under sloshing condition

LNG floating production storage and offloading (FPSO) unit is a new type of floating production unit developed for offshore natural gas fields. It performs the functions of natural gas extraction, pretreatment, liquefaction, and storage. In this study, the heat transfer characteristics of a spiral-wound heat exchanger were studied using numerical simulations, which provides a basis for equipment selection and structural optimization of spiral-wound heat exchangers. The main research contents and conclusions are as follows. Under land-based simulation conditions, the heat transfer coefficient of the shell side of the spiral-wound heat exchanger decreases with an increase in the winding angle of the heat exchange tube, decreases with an increase in the spacing of the heat exchange tube, and increases with an increase in the outer diameter of the heat exchange tube. When the winding angle increased from 5° to 8°, the heat transfer coefficient decreased by 6.70%. The heat transfer coefficient of the shell side decreased by 13.21% when the heat exchange tube spacing increased from 14 to 17 mm. The heat transfer coefficient of the shell side increased by 22.89% when the outer diameter of the heat exchange tube increased from 9 to 12 mm. When the sloshing angle is constant, the heat transfer coefficient of the spiral-wound heat exchanger decreases with an increase in the winding angle and spacing of the heat exchange tubes, and increases with an increase in the outer diameter of the heat exchange tubes. When the structural parameters of the heat exchanger are constant, the heat transfer coefficient decreases as the sloshing angle increases. When the sloshing angle was less than 3°, the sloshing promoted heat transfer on the shell side. When the sloshing angle was higher than 7°, the heat transfer effect of the shell side deteriorated considerably, which weakened the heat transfer performance of the heat exchanger. When the sloshing period is constant, the heat transfer coefficient of the wound heat exchanger decreases with an increase in the winding angle and spacing of the heat exchange tubes, and increases with an increase in the outer diameter of the heat exchange tubes. When the structural parameters of the heat exchanger are constant, the heat transfer coefficient increases with sloshing period. When the sloshing period was greater than 15 s, the influence of sloshing on the heat transfer on the shell side of the heat exchanger was relatively weak.

Load decomposition: A conceptual framework for design and control of thermal energy storage systems in buildings

This work proposes a load decomposition framework for the characterization of thermal energy storage systems (TES) in buildings. This conceptual framework makes it possible to rapidly obtain an estimate of the required rating for the primary equipment and the storage device. The proposed approach employs mathematical methods from signal processing to break down the building load signal into two sub-signals: (a) a primary load provided by the primary production system, and (b) a balancing load provided by the storage system. This information is used to form a Pareto set of solutions that expresses the trade-off between the storage capacity and the primary system size, and hence, comprises the peak shaving potential of any given configuration. A simple decomposition method based on the concept of ”moving average” is tested within this framework on a representative energy model of an office building in the region of Montréal, Québec (QC). The Pareto set is shown to offer a wide range of design and operation solutions for peak shaving, from small water tanks to large underground reservoirs. The results provide clear evidence that TES system not only contributes to peak shaving and load shifting, but also to significantly reduce the primary production unit size.

INCREASING THE EXTRACTION OF VACUUM GAS OIL AT THE ELOU-AVT UNIT

The ELOU-AVT unit is part of a large oil refining complex. This unit is designed for primary processing of oils from various fields, as well as their mixtures. Refining is carried out in order to separate oil into separate fractions (gasoline, kerosene, diesel fuel, fuel oil), which are used as raw materials for secondary oil refining at other units. On the territory of modern refineries, in order to increase the depth of processing of petroleum feedstock, in most cases the following technological units are used: – The isomerization unit is designed for the production of low-boiling high-octane isomerizate used as a component of unleaded motor gasolines. For the production of a low-boiling high-octane component, the plant uses the process of low-temperature isomerization of C5-C6 normal paraffins. – The distillate hydrotreating unit is designed to produce high-quality diesel fuel with low sulfur and nitrogen content, high cetane number, and improved low-temperature properties. – The sulfur production unit is designed to produce solid commercial sulfur by the oxidative conversion of hydrogen sulfide into elemental sulfur. The delayed coking unit is designed to process heavy oil residues (straight-run tar) into lighter gaseous, liquid products and petroleum coke. The process of thermal cracking is the basis for the processing of tar. – The catalytic reformer with preliminary hydrotreatment is designed for the processing of gasoline fractions of oil in order to obtain high-quality gasolines and aromatic hydrocarbons, as well as hydrogen-containing gas (HCG), which is widely used both in petrochemistry and in such oil refining processes as: hydrotreating, hydrocracking, isomerization, etc. Oil refining is a multi-stage process of physical and chemical processing of crude oil, which results in the production of a complex of petroleum products. Industrial primary distillation units are divided into atmospheric (AT), vacuum (VT) and combined (for example, AVT, CDU-AVT, etc.). It is impossible to obtain a single marketable oil product from crude oil directly by one process (with the exception of gases), all of them are obtained by sequential processing at several installations.

A heat recovery-based ecofriendly solar thermal-driven electricity/hydrogen/freshwater multigeneration scheme using LNG regasification: Energy, exergy, economic, and environmental (4E) analysis

The availability of ample solar energy resources holds significant importance for populated islands as it represents a vital avenue for ensuring sustainable energy provision while reducing reliance on external energy sources. The proposed system is designed to offer residential solutions, providing a promising answer to fulfill the varied energy requirements of modern islands. This innovative system integrates parabolic trough solar collectors, a cascaded organic Rankine cycle (ORC), a hydrogen production unit via electrolysis, and a water desalination system through membrane modules. By employing an optimized methodology, this system enhances the thermal efficiency of the proposed setup and enables island communities to access natural gas resources. A robust programming code has been crafted to comprehensively evaluate the system from the standpoints of energy, exergy, economics, and the environment. The system is engineered to accomplish a range of objectives, including the generation of 1.2 MW of electricity, meeting a cooling load of 460 kW, producing 9.7 kg/h of hydrogen, and supplying 33 kg/s of desalinated water. In addition, natural gas is delivered to the consumer network at a rate of 3.09 kg/s. The financial assessment, which includes the initial investment and ongoing maintenance, shows that the cost rate for the whole system is 142 $/h, with an estimated levelized cost of 33.2 Cent/m3 for fresh water. The findings of the environmental assessment indicate that the proposed system holds significant potential for mitigating carbon dioxide (CO2) emissions, with a maximum reduction rate of 254 kg/h. This reduction in CO2 emissions leads to a corresponding decrease in the CO2 emission cost rate, estimated to be approximately 7 $/h.

Inclusive rice seed business: Performance and sustainability

Abstract A collective action approach to rice seed production is an inclusive method involving the community’s active participation at all stages of its execution. This all-inclusive strategy, however, has yet to be thoroughly investigated and published. This study explored how and to what degree an inclusive rice seed business of Gapoktan, based on a collective action approach, might be deployed in a sustainable rice seed company run by community groups. The research comprised the following stages: (1) establishment of a seed production business institution, (2) production of rice seeds, and (3) self-assessment of the performance of the seed production business institution. Institutional data were acquired through a questionnaire that references the European Foundation for Quality Management’s (EFQM) methodology. Three dimensions used were direction (purpose, vision, and strategy; organizational culture and leadership); execution (engaging stakeholders; coasting sustainable value; driving performance transformation); and result (stakeholder perceptions; strategic and operational performance). The study suggests essential findings: The organizational structure of rice seed producers formed is complete regarding its operational functions. The rice seeds produced by Gapoktan have met both the volume and quality standards. From a financial perspective, this rice seed production unit is feasible for further development. However, their social orientation is still relatively high and needs to be more profit-oriented. Uniquely, not all members buy and use Gapoktan seeds. As a result, additional efforts are necessary to provide exceptional service to Gapoktan members.

ИССЛЕДОВАНИЕ СКЛОННОСТИ ФЕНОЛЬНЫХ ВЕЩЕСТВ ВИНОМАТЕРИАЛОВ И ВИН ИЗ ВИНОГРАДА СОРТА КАБЕРНЕ СОВИНЬОН К ОКИСЛЕНИЮ

One of the most important tasks in the production of high-quality red wines is the preservation of intense color, which exposed to atmospheric oxygen, can change and acquire garnet or brown shades. The intensity of color, its shades and stability are determined by the presence of phenolic compounds in wine, among which polymeric forms of polyphenols and anthocyanins have a rich color. In addition, the phenolic substances of red wines are represented by monomeric forms, catechins and procyanidins, etc. The impact of oxygen at various stages of the technological process of making wine can have both positive and negative effects on its chemical composition and organoleptic characteristics. The purpose of this research was to study the effect of oxygen introduced at various technological stages of the preparation of wine materials. As a result of studies of the indicators of the mass concentration of oxygen and phenolic substances that cause wine oxidation, as well as the organoleptic indicators of dry red wines (production samples) made from the Cabernet Sauvignon grape variety in various geographical zones of southern Russia, significant differences have been revealed due to agro-climatic conditions of growing grapes in a particular area, as well as the grape processing technology used at enterprises. Under the conditions of the laboratory and production unit «Micro wine-making», the possibility of using the microoxidation method both at the stage of must and pulp fermentation, and after the fermentation process (stabilization and clarification) for the purpose of deliberate oxidation of polyphenols, was shown. Based on the conducted studies, the optimal dosage of exogenous oxygen, which has a positive effect on the organoleptic characteristics of wine materials, is a concentration of 4-6 mg/dm3 both during microoxidation at the stage of must and pulp fermentation, and at the end of the fermentation of wine.
