In modern conditions, the issues of ensuring the effective functioning of small forms of economic activity are of great importance for the effective functioning of rural areas in social and economic and administrative aspects. In this regard, there is a need to substantiate effective models of economic activity for family forms of agricultural production. These issues are especially relevant for new regions of the Russian Federation. In the course of the study, it was established that peasant farms of Zaporozhye region, included in the cooperative, are differentiated by commodity. Representatives of the commodity group are the least numerous, but they use more than 50% of the total area of agricultural land. In order to improve the efficiency of using the resource potential, increase the number of commodity-type farms and improve the level of well-being of their members, it was proposed to optimize the structure of land use. The proposed land use structure is as follows: cherries - 48%, apricots - 15%, other fruits - 7%, potatoes - 21%, tomatoes - 5%, other crops - 4% of the total volume of agricultural land. Practical implementation of the proposed recommendations will reduce labor costs by 32.7%, but at the same time financial costs increase by 71.4%. Reducing the labor intensity of agricultural production increases the attractiveness of this model for family forms of farming. According to the research results, an increase in the conditional level of profitability by 269 points, as well as the level of family income by 16.2% is noted, which proves the social effect of the implementation of this project for residents of rural areas. A scientifically substantiated model of mutually beneficial cooperation of family forms of agricultural production is an incentive for their participation in the activities of cooperative integration entities.

Genetic variation in the aquaporin TONOPLAST INTRINSIC PROTEIN 4;3 modulates maize cold tolerance.

Cold stress is a major abiotic stress that threatens maize (Zea mays L.) production worldwide. Understanding the molecular mechanisms underlying cold tolerance is crucial for breeding resilient maize varieties. Tonoplast intrinsic proteins (TIPs) are a subfamily of aquaporins in plants. Here, we report that TIP family proteins are involved in maize cold tolerance. The expression of most TIP genes was responsive to cold stress. Overexpressing TIP2;1, TIP3;2 or TIP4;3 reduced the cold tolerance of maize seedlings, while loss-of-function mutants of TIP4;3 exhibited enhanced cold tolerance. Candidate gene-based association analysis revealed that a 328-bp transposon insertion in the promoter region of TIP4;3 was strongly associated with maize cold tolerance. This transposon insertion conferred cold tolerance by repressing TIP4;3 expression through increased methylation of its promoter region. Moreover, TIP4;3 was found to suppress stomatal closure and facilitate reactive oxygen species (ROS) accumulation under cold stress, thereby inhibiting the expression of cold-responsive genes, including DEHYDRATION-RESPONSIVE ELEMENT BINDING FACTOR 1 (DREB1) genes and a subset of peroxidase genes, ultimately attenuating maize cold tolerance. This study thus elucidates the mechanism underlying TIP-mediated cold tolerance and identifies a favourable TIP4;3 allele as a potential genetic resource for breeding cold-tolerant maize varieties.

Defensive polyketides produced by an abundant gastropod are candidate keystone molecules in estuarine ecology.

Secondary metabolites often function as antipredator defenses, but when bioactive at low concentrations, their off-target effects on other organisms may be overlooked. Candidate "keystone molecules" are proposed to affect community structure and ecosystem functions, generally originating as defenses of primary producers; the broader effects of animal chemistry remain largely unexplored, however. Here, we characterize five previously unreported polyketides (alderenes A to E) biosynthesized by sea slugs reaching exceptional densities (up to 9000 slugs per square meter) in Northern Hemisphere estuaries. Alderenes comprise only 0.1% of slug wet weight, yet rendered live slugs or dead flesh unpalatable to three co-occurring consumers, making a potential food resource unavailable and redirecting energy flow in critical nursery habitat. Alderenes also displaced infauna from the upper sediment of the mudflat but attracted ovipositing snails. By altering communities, such compounds may have unexpected cascading effects on processes ranging from bioturbation to reproduction of species not obviously connected to the producing organisms, warranting greater attention by ecologists.

From Conversation to Interaction: A Pedagogical Exploration of Applying Conversation Analysis in EFL Classrooms

Within the communicative language teaching approach, current instructional materials often lack explicit guidance or fail to provide L2 learners with a wide range of resources in the target language. Conversation analysis (CA), which focuses on authentic talk, has been proposed as a potential resource for language classrooms. This study examines the effectiveness of using CA as a pedagogical approach in an EFL classroom and its impact on learners’ attitudes toward English language learning. The study engaged eight adult learners in a structured program, encompassing a pre-test, a 4-week explicit CA-informed instruction, and a post-test. After four weeks, learners demonstrated progress in their knowledge and skills of interaction, different aspects of English speaking, interactional competence, and confidence in speaking English. Additionally, the CA-informed instruction positively influenced learners’ attitudes toward English language learning and their appreciation of interactional features. The results strongly suggest that language teachers should consider incorporating CA insights into their teaching practices to enhance both linguistic and attitudinal outcomes.

PbRVE6 Promotes Anthocyanins Accumulation in Pear Fruit Peel by Regulating Key Biosynthetic Genes.

Red peel color, a desirable trait in pears, is determined by anthocyanin accumulation. While REVEILLE (RVEs) transcription factors regulate anthocyanin biosynthesis in some plant species, their role in pear peel has not been well-studied. This study investigates the function of RVEs in anthocyanin biosynthesis in 'Zaosu' (low anthocyanin content) and its red bud mutant, 'Red Zaosu' (high anthocyanin content) fruit peel. Consistent with higher anthocyanin content, 'Red Zaosu' pears exhibited increased PbRVE6 expression compared to 'Zaosu', while PbRVE3a and PbRVE3b levels remained unchanged. Additionally, PbRVE6 was localized to the nucleus. Overexpression of PbRVE6 in 'Zaosu' pear pericarp significantly increased anthocyanin content and upregulated key anthocyanin pathway genes PbANS and PbUFGT. Conversely, VIGS silencing of PbRVE6 in 'Red Palacer' pears led to decreased expression of PbANS and PbUFGT and a slight reduction in anthocyanin content. Yeast one-hybrid and dual-luciferase assays confirmed that PbRVE6 can bind and activate the promoters of PbANS and PbUFGT. These findings demonstrate that PbRVE6 promotes anthocyanin accumulation in pear peel by directly regulating PbANS and PbUFGT expression. This study provides a valuable foundation for understanding the regulatory network of anthocyanins in pear peels, and offers potential genetic resources for the production of new pear germplasm.

Genome-wide analysis of the Amorphophallus konjac AkCSLA gene family and its functional characterization in drought tolerance of transgenic arabidopsis

BackgroundAmorphophallus konjac (A. konjac), a perennial tuberous plant, is widely cultivated for its high konjac glucomannan (KGM) content, a heteropolysaccharide with diverse applications. The cellulose synthase-like (CSL) gene family is known to be a group of processive glycan synthases involved in the synthesis of cell-wall polysaccharides and plays an important role in the biological process of KGM. However, in A. konjac the classification, structure, and function of the AkCSLA superfamily have been studied very little.ResultsBioinformatics methods were used to identify the 11 AkCSLA genes from the whole genome of Amorphophallus konjac and to systematically analyze their characteristics, phylogenetic evolution, promoter cis-elements, expression patterns, and subcellular locations. Phylogenetic analysis revealed that the AkCSLA gene family can be divided into three subfamilies (Groups I- III), which have close relationships with Arabidopsis. The promoters of most AkCSLA family members contain MBS elements and ABA response elements. Analysis of expression patterns in different tissues showed that most AkCSLAs are highly expressed in the corms. Notably, PEG6000 induced down-regulation of the expression of most AkCSLAs, including AkCSLA11. Subcellular localization results showed that AkCSLA11 was localized to the plasma membrane, Golgi apparatus and endoplasmic reticulum. Transgenic Arabidopsis experiments demonstrated that overexpression of AkCSLA11 reduced the plant’s drought tolerance. This overexpression also inhibited the expression of drought response genes and altered the sugar components of the cell wall. These findings provide new insights into the response mechanisms of A. konjac to drought stress and may offer potential genetic resources for improving crop drought resistance.ConclusionIn conclusion, the study reveals that the AkCSLA11 gene from A. konjac negatively impacts drought tolerance when overexpressed in Arabidopsis. This discovery provides valuable insights into the mechanisms of plant response to drought stress and may guide future research on crop improvement for enhanced resilience.

Antifungal activity mechanisms of venturicidin A against Botrytis cinerea contributes to the control of gray mould.

Gray mould caused by Botrytis cinerea, an airborne phytopathogenic pathogen, infects many economically important fruits and vegetables. Secondary metabolic products of microorganisms are potential resources for developing fungicide alternatives. Venturicidin A (VentA) is produced by a biocontrol strain Streptomyces pratensis S10. Although a broad spectrum of antifungal activity has been reported for VentA, little is known about its antifungal mechanisms against B. cinerea. Venturicidin A exhibited a strong hyphal inhibition of B. cinerea with an EC50 (effective concentration causing 50% growth inhibition) value of 1.08 μg mL-1 on PDA medium. Different concentrations of VentA inhibited spore germination with an inhibition rate of 49-86%. Venturicidin A also displayed protective and curative activity against the development of B. cinerea infection on tomato fruit, reducing disease incidence by ≈28-78%. Additionally, VentA effectively reduced the disease index and lesion length of gray mould on tomato plant. Meanwhile, VentA downregulated the expression levels of six genes related to pathogenicity in B. cinerea. As observed by scanning electron microscopy, B. cinerea spores and hyphae are abnormal after treatment with VentA. Propidium iodide staining revealed that VentA destroyed cell membrane integrity, causing cytoplasmic leakage. Furthermore, VentA induced accumulation of reactive oxygen species and upregulated the genes encoding subunits for NADPH oxidase in B. cinerea. This study indicated that VentA displayed strong inhibitory activity against B. cinerea and effectively reduced gray mould disease. Thus, VentA has the potential to manage gray mould caused by B. cinerea. © 2024 Society of Chemical Industry.

This study aims to conduct a thorough examination of Pakistan’s energy sector, with a specific focus on renewable energy (RE) and nonrenewable energy (non-RE) sources. It intends to delve into the potential of solar and hydropower resources within Pakistan and their capacity to mitigate the effects of climate change, thus centering the discussion on RE, particularly solar and hydropower. Adopting secondary data sources, this study seeks to provide a comprehensive analysis of the current state of Pakistan’s energy sector and the challenges that it faces. One of the key findings highlighted in the analysis is the serious problem within Pakistan’s energy sector: existing institutions struggle to cope with the increasing demand for energy owing to insufficient growth in power generation capacity. This inadequacy has led to an increase in CO2 emissions, primarily driven by the country’s growing reliance on fossil fuels to meet its energy needs. Despite this challenge, Pakistan possesses substantial potential for Resources, particularly solar energy and hydropower. Following an evaluation of renewable energy resources, this study proposes recommendations to support the adoption and utilization of renewable energy as a critical component of sustainable growth. These suggestions are geared toward accelerating the transition to renewable energy sources, thus positioning Pakistan for a more sustainable and resilient energy future. This research paper underscores the urgency of addressing the shortcomings in Pakistan’s energy sector and emphasizes the pivotal role of renewable energy, especially solar and hydropower, in mitigating climate change and fostering sustainable development. By leveraging its abundant renewable energy resources and implementing strategic measures, Pakistan can chart a path toward a more environmentally friendly and economically viable energy landscape.

Resource abundance of cobalt-rich ferromanganese crusts in the KC-8 seamount, West Pacific

We have estimated the resource potential of cobalt-rich ferromanganese crusts (CFCs) on the summit area of the KC-8 seamount in the West Pacific, based on the acoustic backscatter intensity (ABI), ROV video footage, and CFC thickness measurements. To estimate the spatial distribution of CFC across 13 equally divided blocks within a 360 km2 area, shipboard and deep-tow ABIs were compared with visual data. The presence of CFCs is evident in the areas where ABI is higher than average, validating the use of ABI data to delineate the exposure of CFCs. With high accuracy in distinguishing between CFCs and sediment-dominant areas, the distribution area of CFCs was precisely calculated. The variation in CFC thickness across the KC-8 seamount summit was measured through CFC samples retrieved using a CFC corer. CFC thickness is highly variable even between adjacent sites, but it shows a roughly increasing trend from south to northwest. Based on the CFC distribution area associated with thickness, we calculated a CFC resource abundance. Of the estimation, 82% have remained on the gentle slope (<10°) areas, which can be accessible for future mining. Overall, our study suggests that the combination of an acoustic survey with reliable thickness information is highly effective in estimating CFC abundance.

Evaluation of the potential power generation resources in SAARC region for sustainable energy trade

AbstractThis article presents a comprehensive review on the contemporary condition of electrical energy in the SAARC countries with particular focus on conventional as well as renewable resources. The region lies at the center of the Asia with a dense population where demand and supply gap has always been a challenging factor for the governments. In addition, the region has observed enormous industrial growth during past two and half decades whose sustainability is totally dependent upon the continuous supply of energy. A bulk of valuable literature has been published in recent years that addresses the challenges, infrastructure improvements margins and several schemes to mitigate the energy deficiency in the region but most of it focuses upon either generation or transmission. This article covers this gap and presents to‐the‐point data that can be used for future forecasting, cross‐border trade possibilities and indigenous energy generation for remote and islanded regions within and across the SAARC mainland. A detailed review on electrical power generation potential by exploiting the renewable energy resources (RERs), generation capacity, installed capacity, energy short fall and transmission and distribution (T&D) losses is presented for each SAARC country and the results are presented in forms of tables and graphs. It can be inferred from the data presented in this paper that the energy crisis of the SAARC region can be overcome by mutual trade among the land‐connected countries by transporting the electrical energy, generated through RERs, across the borders. The paper concludes that the region has enormous potential for renewable energy available in form of hydal, solar, wind and biomass that, if maturely harnessed, can only not fulfil the local demands of the region but also be exported to establish the framework of cross‐border energy trade in future for sustainability of industrial and domestic utilization.

Nuclear Decommissioning and Sustainable Environment: Insights on Decontamination Processes

Nuclear energy accounts for ≈10% of global energy production, positioning it as a promising solution for achieving carbon neutrality amid escalating concerns over climate change. Nonetheless, the effective management of radioactive waste, which can remain hazardous for up to one hundred thousand years, presents considerable challenges that must be addressed to uphold public trust and safeguard environmental safety. This review outlines the fundamental stages of nuclear decommissioning including strategic planning, decontamination, dismantling, remediation, encapsulation, deregulation, and site reuse as a critical component of sustainable environmental practices. The review also highlights the significance of efficient decontamination processes in reducing waste generation. Various decontamination techniques, including mechanical, electromechanical, chemical, and advanced methods such as laser and plasma decontamination, are evaluated for their effectiveness and limitations. Moreover, the review emphasizes the need to enhance the recovery and recycling of ion exchange resin and potential radionuclides during decontamination processes to minimize waste and to address the depletion of potential radionuclide resources. Future research should prioritize the development of innovative techniques for decontamination and radioactive waste management, fostering sustainable decommissioning and supporting the ongoing development of nuclear energy in an environmentally responsible manner.

Confiscated property from illegality to common good: requirements for a necessary resignification

The property confiscated from organised crime is the outcome of a particular communing process. Italian law provides for a primary compensatory function, implemented in the final destination of their use for collective, institutional, or social purposes. Despite the critical management issues, which prolong the allocation process, the strong symbolic value is enriched by the significance of compensation for the mafia oppression that certain territories suffer. In addition, confiscated properties constitute a potential resource for the territory from an economic point of view, capable of supporting job opportunities and enhancing useful services and activities for the community involved. The resignification of confiscated property requires specific focus on the various phases of the interventions. It is not just a question of a mere change of legal status or intended use but of a profound reorganisation of the architectural, material, technological, environmental, and managerial characteristics. This is consequent and consistent with the interweaving of legal, social, cultural and environmental aspects triggered by confiscation.

Inhibition of Accumulation of Neutral Lipids and Their Hydroperoxide Species in Hepatocytes by Bioactive Allium sativum Extract

Our ongoing research suggests that extracts from plant-based foods inhibit the accumulation of lipid droplets (LDs) and oxidized lipid droplets (oxLDs) in liver cells. These findings suggest their potential use in the alleviation of metabolic dysfunction-associated fatty liver disease (MAFLD) and its most severe manifestation, metabolic dysfunction-associated steatohepatitis (MASH). Allium extracts (ALs: AL1–AL9) were used to assess their ability to reduce lipid droplet accumulation (LDA) and oxidized lipid droplet accumulation (oxLDA) by inhibiting neutral lipid accumulation and oxidation in LD. Among the tested Allium extracts, AL1, AL3, and AL6 demonstrated substantial inhibitory effects on the LDA. Furthermore, AL1 extract showed real-time inhibition of LDA in HepG2 cells in DMEM supplemented with oleic acid (OA) within 12 h of treatment. Our lipidomic approach was used to quantify the accumulation and inhibition of intracellular triacylglycerol (TAG) and oxidized TAG hydroperoxide [TG (OOH) n = 3] species in hepatocytes under OA and linoleic acid loading conditions. These results suggest that Allium-based foods inhibit LD accumulation by decreasing intracellular lipids and lipid hydroperoxides in the hepatocytes. The metabolomic analysis of AL1—the bioactive LDAI extract—using both LC-MS/MS and 1D-NMR [1H, 13C, and Dept (135 and 90)] approaches revealed that AL1 contains mainly carbohydrates and glucoside metabolites, including iridoid glucosides, as well as minor amino acids, organosulfur compounds, and organic acids such as the antioxidant ascorbic acid (KA2 = S13), and their derivatives, suggesting that AL1 could be a potential resource for the development of functional foods and in drug discovery targeting MAFLD/MASH and other related diseases.

INCREASING THE HUMAN RESOURCES POTENTIAL OF STATE AUDIT BODIES AS A BASIS FOR IMPROVING THE EFFICIENCY AUDIT MECHANISM

Recent economic and financial scandals worldwide, the growth of the shadow economy, the increase in funds concealed from the budget, the rise of corruption, and insufficient adherence to financial discipline create very serious problems. The development of an audit system that creates a transparent and comprehensive informational environment for the government and the public, and plays a key role in economic regulation, is aimed at addressing these serious issues and improving the economic and managerial environment. The purpose of the paper is to explore how increasing the human resources potential of state audit bodies serves as a basis for improving the efficiency audit mechanism. The improvement of the functioning of the state audit system and the enhancement of the knowledge and expertise of personnel and specialists working in this field are based on the critical need to assess and refine the existing system. At the current stage of development, improving the mechanisms of state audit and financial control, as well as monitoring the effective use of budget expenditures, has become a priority. In this context, the concept of state budget policy has undergone changes and is now focused on results-based management. To achieve these goals, new approaches to assessing economic efficiency are being developed, with the improvement of the efficiency audit mechanism being the main focus. The development of auditing institutions plays an important role in accelerating the country's socio-economic development. As a result of these institutions' activities, it becomes possible to identify new financial and economic resources necessary for economic growth. Increasing transparency in society and strengthening financial discipline in economic activities are also closely linked to the work of these institutions. The paper examines the issues of enhancing the knowledge and experience of personnel and specialists, who play a key role in the development of the audit institute.

Declines in victims calling the police in 21st-century America: how the trends vary by race/ethnicity and racial-immigration contexts

Victims’ willingness to call the police facilitates access to the justice system and potential resources. Research shows a decline in police notification in the United States in recent decades, but the research has not assessed variation in trends across different racial/ethnic groups and different racial-immigration contexts. This study uses the National Crime Victimization Survey (NCVS) data from 52 metropolitan areas in the United States from 2000 to 2015 to investigate how victims across racial/ethnic groups vary in the likelihood of crime reporting based on geographic context. The results show that Black, Latino, and Asian victims’ crime-reporting behavior is influenced by the racial/ethnic and immigrant composition of the metropolitan areas. While the likelihood of police notification between racial/ethnic minorities and Whites is often similar when averaged across areas, minority victims in areas with higher percentages of Black or immigrant residents show a lower likelihood of crime reporting than their White counterparts. The higher percentage of immigrants is also associated with a steeper decline in the reporting of property crimes. These findings demonstrate the context-dependent nature of crime reporting. They help explain mixed evidence on the associations of race/ethnicity with police notification. To understand the crime-reporting behavior of victims, especially those who are racially marginalized, more attention to racial-immigration contexts is needed.

Stable isotope ratios indicate trophic niche overlap in three sympatric delphinid species in the Eastern Ionian Sea

AbstractStudying the sympatric ecology of closely related marine top predator species is of interest both from an ecological and conservation standpoint, because it provides insights into ecosystem functioning, how such species avoid competitive exclusion, and how human stressors may impact these patterns. In this study, we examine the isotopic niche of three sympatric dolphin species that inhabit the eastern Ionian Sea: the common dolphin (Delphinus delphis), the striped dolphin (Stenella coeruleoalba), and the common bottlenose dolphin (Tursiops truncatus). We used carbon, nitrogen, and sulfur isotope ratios to construct three‐dimensional isotope niches and calculate niche sizes and their overlaps among the three species to study interspecific competition for resources. Common dolphin niche overlapped with that of the striped dolphin by 77%, suggesting potential resource competition between these two species. The niche overlap between striped/common dolphins and bottlenose dolphins was much lower (47%). Large differences in isotopic ratios were found between the bottlenose dolphins of the Ionian Sea and those of a largely isolated population in the adjacent semienclosed Gulf of Ambracia, further corroborating the previously documented isolation between the two populations.

Expression and degradation function analysis of the key genes from Arthrobacter nitroquajacolicus HW08 in Lactococcus lactis for the degradation of swainsonine

In order to mitigate the adverse effects of madrassa poisoning disease on our livestock industry and to fully utilize the potential pasture resources, biodegradation of locoweed can remove swainsonine, the major toxic component of locoweed, so that the locoweed can be used as high-quality forage. Arthrobacter nitroquajacolicus HW08 can stably and efficiently degrade swainsonine. In this study, Lactococcus lactis, as a food-grade microorganism, was used as a vector to express four key degradation genes from A. nitroquajacolicus HW08. Subsequently, liquid chromatography was employed to evaluate the swainsonine-degrading performance. The crude enzyme solution extracted from the L. lactis strain transformed with the ethanol dehydrogenase gene A1R6C3 degraded 323.4 μg of swainsonine in 24 h at 30 ℃. The crude enzyme solutions from the L. lactis strains transformed with the genes encoding glutathione synthase, esterase/acyl hydrolase, and glycosyltransferase did not show any degradation ability for swainsonine when being used alone but degraded about 140.5 μg of swainsonine when being used in mixture. The findings will help the clinical promotion of swainsonine-degrading engineering strains and provide new research ideas for the prevention and treatment of swainsonine poisoning in animals and the detoxification and utilization of locoweed.
