Published: April 2024

The best-characterized functional motifs of the potyviral Helper-Component protease (HC-Pro) responding for aphid transmission, RNA silencing suppression, movement, symptom development, and replication are gathered in this review. The potential cellular protein targets of plant virus proteases remain largely unknown despite their multifunctionality. The HC-Pro catalytic domain, as a cysteine protease, autoproteolytically cleaves the potyviral polyproteins in the sequence motif YXVG/G and is not expected to act on host targets; however, 146 plant proteins in the Viridiplantae clade containing this motif were searched in the UniProtKB database and are discussed. On the other hand, more than 20 interactions within the entire HC-Pro structure are known. Most of these interactions with host targets (such as the 20S proteasome, methyltransferase, transcription factor eIF4E, and microtubule-associated protein HIP2) modulate the cellular environments for the benefit of virus accumulation or contribute to symptom severity (interactions with MinD, Rubisco, ferredoxin) or participate in the suppression of RNA silencing (host protein VARICOSE, calmodulin-like protein). On the contrary, the interaction of HC-Pro with triacylglycerol lipase, calreticulin, and violaxanthin deepoxidase seems to be beneficial for the host plant. The strength of these interactions between HC-Pro and the corresponding host protein vary with the plant species. Therefore, these interactions may explain the species-specific sensitivity to potyviruses.

The enzymatic reaction stage (ECS) of oolong tea processing plays an important role in the formation of the flavor quality of the oolong tea. To investigate the dynamic changes in the volatile and non-volatile components in the leaves of oolong tea during the ECS, metabolomic studies were carried out using the leaf samples collected at different stages of the ECS of Aijiao oolong tea. Out of the identified 306 non-volatile metabolites and 85 volatile metabolites, 159 non-volatile metabolites and 42 volatile metabolites were screened out as key differential metabolites for dynamic changes during the ECS. A multivariate statistical analysis on the key differential metabolites showed that the accumulations of most metabolites exhibited dynamic changes, while some amino acids, nucleosides, and organic acids accumulated significantly after turning-over treatment. The evolution characteristics of 27 key precursors or transformed VOCs during the ECS of Aijiao oolong tea were clarified, and it was found that the synthesis of aroma substances was mainly concentrated in lipids as precursors and glycosides as precursor pathways. The results revealed the dynamic changes in the flavor metabolites in the ECS during the processing of Aijiao oolong tea, which provided valuable information for the formation of the characteristic flavor of Aijiao oolong tea.

Published: April 2024

Biodegradable polymers have been extensively researched in the field of biomedicine. Polylactic-co-glycolic acid (PLGA), a biodegradable polymer material, has been widely used in drug delivery systems and has shown great potential in various medical fields, including vaccines, tissue engineering such as bone regeneration and wound healing, and 3D printing. Cancer, a group of diseases with high mortality rates worldwide, has recently garnered significant attention in the field of immune therapy research. In recent years, there has been growing interest in the delivery function of PLGA in tumor immunotherapy. In tumor immunotherapy, PLGA can serve as a carrier to load antigens on its surface, thereby enhancing the immune system’s ability to attack tumor cells. Additionally, PLGA can be used to formulate tumor vaccines and immunoadjuvants, thereby enhancing the efficacy of tumor immunotherapy. PLGA nanoparticles (NPs) can also enhance the effectiveness of tumor immunotherapy by regulating the activity and differentiation of immune cells, and by improving the expression and presentation of tumor antigens. Furthermore, due to the diverse physical properties and surface modifications of PLGA, it has a wider range of potential applications in tumor immunotherapy through the loading of various types of drugs or other innovative substances. We aim to highlight the recent advances and challenges of plga in the field of oncology therapy to stimulate further research and development of innovative PLGA-based approaches, and more effective and personalized cancer therapies.

Published: April 2024

Over a century ago, phenolic formaldehyde (PF) resin was developed and continues to increase in yield due to its diverse applications. However, PF resin is a thermosetting plastic lacking fluidity and moldability, which are nondegradable in natural environments, leading to severe threats to fossil resources as well as global environmental crises. As a result, recycling PF resin is extremely important. In this review, we provide the recent advances in the recycling of PF resin, which includes mechanical recycling, chemical recycling, and utilization of carbon-based materials. The advantages and disadvantages of each strategy are evaluated from a green chemistry perspective. This article aims to attract interest in PF resin design, synthesizing, application and recycling, offering useful suggestions.

Published: April 2024

In efforts to achieve the goal of reducing ship emissions in the fight against climate change, reducing fuel consumption by making ships lighter is stated as one of the solutions. In this study, the possibilities of making composite equivalents of propellers, which are the most complex ship elements and traditionally produced from metal materials, are investigated with the advantages of additive manufacturing, which offers a rapid production opportunity for such forms. In this way, a lighter composite propeller and, therefore, a lighter ship will be achieved, and negative environmental impacts, especially harmful emissions, will be reduced. In the study, a 1/14-scale ship propeller was produced through the material extrusion method of additive manufacturing using an HDPE composite containing long carbon fiber with a 15% weight fraction. An attempt to reduce flexibility with an epoxy-carbon fabric prepreg coating was made, as the flexibility has negative effects on the performance of the produced propeller. The propeller tunnel test showed that the applied carbon fabric epoxy prepreg helped to improve the propeller’s performance by decreasing the flexibility of the propeller and reducing the deformation at the tips. At the same time, the propeller weight was decreased by 60% compared to its metal counterparts.

Published: April 2024

The Baihetan reservoir region is characterized by complex geomorphology, significant altitude differences, and rugged terrain. Geological hazards in such areas are often characterized by high concealment, wide distribution, and difficulty in field investigation. Traditional identification techniques are unable to detect and monitor geological hazards on a large scale with high efficiency and accuracy. In recent decades, interferometric synthetic aperture radar (InSAR) techniques, such as small baseline subset InSAR (SBAS-InSAR), have been widely applied to landslide identification. However, due to factors such as vegetation and the degree of landslide deformation, single-band synthetic aperture radar (SAR) still has certain limitations in detecting landslides. In this study, SBAS-InSAR was conducted based on ALOS-2 and Sentinel-1 ascending-descending images covering the Baihetan reservoir region. Deformation identification results were utilized to conduct a statistical analysis of the SAR detection performance and landslide characteristics, and the effect of vegetation on the detection effectiveness of different SAR bands was discussed. The study revealed that when surface vegetation coverage reaches a high degree, the percentage of areas with coverage greater than 0.6 is greater than 95%, the SAR coherence is mainly affected by vegetation thickness; the comparison of the difference change in the average coherence of the C/L bands among the four vegetation types shows that the ratio of the average coherence of the L-bands to the C-bands increases by a factor of three with the increase in thickness and the transition from crops to shrubs and trees. The results showed that the L-band has better detectability than the C-band in alpine-canyon terrain with vegetation coverage and complex vegetation composition. However, considering the high temporal resolution and accessibility of Sentinel-1 SAR data, it is still the main data choice for wide-area identification of landslides in the reservoir area, while other satellite-borne SAR data with different wavelengths and resolutions, such as ALOS, can be used to assist in the identification and monitoring of landslide hazards with significant magnitude of deformations and dense vegetation coverage. Therefore, the combined utilization of multi-band SAR data has the potential to enhance the dependability of landslide identification and monitoring, resulting in more accurate detection results.
Algorithm for the Weak Target Joint Detection and Ambiguity Resolution Based on Ambiguity Matrix
Authors: Mao Yitong , Song Chong , Wang Bingnan
Published: April 2024

The looking-down mode of space airship bistatic radars faces complex sea–land clutter, and the mode of wide-range surveillance and the over-sight detection of the satellite platform generates a low SNR and range–Doppler ambiguity. The method traditionally used involves the transmission of multiple Pulse Repetition Frequencies (PRFs) and correlating them to solve the ambiguity. However, with a low SNR, the traditional disambiguation fails due to the large number of false alarms and target omissions. In order to solve this problem, a new algorithm for multi-target joint detection and range–Doppler disambiguation based on an ambiguity matrix is presented. Firstly, all possible state values corresponding to the ambiguous sequence are filled into the ambiguity matrix one by one. Secondly, the state values in the matrix cell are divided into several groups of subsequences according to the PRF. By disambiguating multiple sets of subsequences, performing subsequence fusion, and then undertaking point aggregation, the targets can be effectively detected in scenarios with a strong clutter rate, the false alarms can be suppressed, and the disambiguation of the range and Doppler is completed. The simulation shows that the proposed algorithm has the strong ability to detect targets and perform ambiguity resolution in the scenario of a multi-target and multi-false alarm.

Published: April 2024

This study extensively examines the estimation of irrigation water requirements using different methodologies based on Earth Observation data. Specifically, two distinct methods inspired by recent remote sensing and satellite technology developments are examined and compared. The first methodology, as outlined by Maselli et al. (2020), focuses on using Sentinel-2 MSI data and a water stress scalar to estimate the levels of actual evapotranspiration and net irrigation water (NIW). The second methodology derives from the work of D’Urso et al. (2021), which includes the application of the Penman–Monteith equation in conjunction with Sentinel-2 data for estimating key parameters, such as crop evapotranspiration and NIW. In the context of the Bekaa Valley in Lebanon, this study explores the suitability of both methodologies for irrigated potato crops (nine potato fields for the early season and eight for the late season). The obtained NIW value was compared with measured field data, and the root mean square errors were calculated. The results of the comparison showed that the effectiveness of these methods varies depending on the growing season. Notably, the Maselli method exhibited better performance during the late season, while the D’Urso method proved more accurate during the early season. This comparative assessment provided valuable insights for effective agricultural water management in the Bekaa Valley when estimating NIW in potato cultivation.

Published: April 2024

This study utilizes Thermal Infrared (TIR) imaging technology to detect hotspots in photovoltaic (PV) modules of solar power plants. Unmanned aerial vehicle (UAV)-based TIR imagery is crucial for efficiently analyzing fault detection in solar power plants. This research explores optimal operational parameters for generating high-quality TIR images using UAV technology. In addition to existing variables such as humidity, emissivity, height, wind speed, irradiance, and ambient temperature, newly considered variables including the angle of incidence between the target object and the thermal infrared camera are analyzed for their impact on TIR images. Based on the solar power plant’s tilt (20°) and the location coordinate data of the hotspot modules, the inner and outer products of the vectors were used to obtain the normal vector and angle of incidence of the solar power plant. It was discovered that the difference between measured TIR temperature data and Land Surface Temperature (LST) data varies with changes in the angle of incidence. The analysis presented in this study was conducted using multiple regression analysis to explore the relationships between dependent and independent variables. The Ordinary Least Squares (OLS) regression model employed was able to explain 63.6% of the variability in the dependent variable. Further, the use of the Condition Number (Cond. No.) and the Variance Inflation Factor (VIF) revealed that the multicollinearity among all variables was below 10, ensuring that the independence among variables was well-preserved while maintaining statistically significant correlations. Furthermore, a positive correlation was observed with the actual measured temperature values, while a negative correlation was observed between the TIR image data values and the angle of incidence. Moreover, it was found that an angle of incidence between 15° and 20° yields the closest similarity to LST temperature data. In conclusion, our research emphasizes the importance of adjusting the angle of incidence to 15–20° to enhance the accuracy of TIR imaging by mitigating overestimated TIR temperature values.

Published: April 2024

Spectrally resolved interferometry utilizing a femtosecond laser is widely employed for absolute distance measurement. However, deviations in the output time pulse of the conventional algorithm through inverse Fourier transform are inevitable. Herein, an improved data processing algorithm employing a time-shifting parameter is proposed to improve the accuracy of spectrally resolved interferometry. The principle of the proposed time-shifting algorithm is analyzed theoretically after clarifying the deviation source of the conventional algorithm. Simulation and experimental work were conducted to indicate the improvement in the accuracy of the output absolute distance. The results demonstrated that the proposed algorithm could reduce the deviation of output distances towards the reference values, reaching 0.58 μm by half compared to the conventional algorithm. Furthermore, the measurement uncertainty was evaluated using the Guide to the Expression of Uncertainty in Measurement (GUM), resulting in an expanded uncertainty of 0.71 μm with a 95% confidence.

Authors: Lv Song , Lai Yin
Published: April 2024

The ship-mounted photovoltaic (PV) system was an approach to solve the problem of pollution caused by excessive energy consumption during navigation. However, PV systems used on ships faced problems such as small installation areas, which prevented PV power generation from being utilized on a large scale. This article proposes a space-saving photovoltaic double-skin façade (PV-DSF) window system, which could be used in conjunction with ships to address the insufficient ship-mounted photovoltaics. In this paper, we propose a space-saving photovoltaic double-skinned façade (PV-DSF) window system that could be used in conjunction with a ship to solve the problem of insufficient space for onboard photovoltaics. According to the working principle of the system, we established a mathematical model corresponding to the actual heat transfer process and, at the same time built up a corresponding experimental test rig for thermoelectric performance measurement, and verified the accuracy of the proposed mathematical model based on the experimental results. Finally, the effect of different parameters on the performance of the system and the energy performance of the system on board the ship was discussed using a mathematical model. The simulation data showed that the increase of solar radiation intensity, wind speed, and PV coverage had a positive effect on the system’s power generation, while the ambient temperature had a negative effect. The system, in combination with a passenger ship, was able to provide 53.2 kWh of annual electricity generation and reduced CO2 emissions by 17 kg.

Published: April 2024

This study aims to analyze the changes in the agrifood supply chain (AFSC) configurations in Latin America (LATAM) imposed by the markets as an effect of the COVID-19 pandemic. This paper analyzes the results of mobility trends, production rates, logistics performance, and the strategies developed by managers and decision makers of the organizations of the agro-industrial sector for supply chain configurations during the early stages of the pandemic in a food-exporting region that contributes 14% of the world’s production of agricultural and fishery products. Through a literature review of reports and scientific articles on the behavior of the pandemic published by international organizations, research centers, and researchers around the AFSC in LATAM, the impacts on logistical disruptions, configuration strategies, and disruptive technologies applied in Latin American agrifood supply chains during the lockdown are identified. As a result of this reconfiguration of the AFSC, the development of short supply chains and the digitalization of supply based on electronic commerce were the most used strategies during COVID-19 in LATAM. The results of this study show that Mexico, Chile, and Brazil maintained a prominent position as leaders in the different logistics indicators for the AFSC by developing strategies that include short supply chains and the digitalization of supplies based on electronic commerce. Finally, this study also highlights the imminent need to address new research and theories on the reconfiguration of the AFSC, which allows expanding analytical capabilities in organizations to face future risks and challenges that will enable the reconfiguration of the supply chain in the face of catastrophic scenarios such as COVID-19.

Authors: Ben Ghrbeia Suliman , Alzubi Ahmad
Published: April 2024

In an era where digital transformation (DGT) is pivotal for organizational resilience and competitiveness, integrating sustainability into the digitalization process has emerged as a strategic imperative. By employing the resource-based view (RBV) and the dynamic capability theory (DCT), this study delves into the micro-foundations of DGT in medium- and large-sized enterprises, highlighting the synergistic role of managerial digital literacy in fostering digital transformation through the mediation role of digital readiness and the moderation role of the top management team (TMT). To fulfill the objectives of this study, data were collected through a cross-sectional mail survey, yielding responses from 235 senior and mid-level managers across medium- and large-sized firms in various industries within Turkey. Results have confirmed that digital literacy significantly enhances digital transformation and readiness, laying the groundwork for successful digital transformation initiatives. Digital readiness significantly mediates the relationship between digital literacy and digital transformation, indicating that enhancing digital literacy is a crucial step that indirectly influences digital transformation through improving digital readiness. The moderating effect of top management team (TMT) behavioral integration on the digital literacy and digital readiness link is affirmed, highlighting its critical role in facilitating organizational digital adaptation. TMT behavioral integration does not positively moderate the direct relationship between digital literacy and digital transformation. The study’s findings offer a novel lens on digital transformation, revealing that the interplay between digital literacy, readiness, and TMT behavioral integration crafts a strategic scaffold for enhancing organizational agility and competitive edge in the digital era.
Striving for Sustainable Solutions: Optimizing Utility Properties of Recycled Paper with the Addition of Wet Strength Resin
Authors: Małachowska Edyta
Published: April 2024

Paper producers are increasingly challenged to meet customer demands for high-quality sanitary papers amidst rising price pressures and diminishing quality of recycled fibers. One promising avenue for enhancing paper quality involves augmenting wet strength. For this purpose, synthetic wet strength resins are used, among other things. This study explores the efficacy of utilizing a polyamide-epichlorohydrin resin-based agent for the internal sizing of white wastepaper. Such chemicals, when added to cellulosic fibers in proper amounts before the paper is made, can not only improve water resistance and air permeability of the finished product but also significantly affect both the dry and wet strength paper, which is a crucial aspect for sanitary papers. This study shows that the appropriate addition of resin allows the wetted recycled paper to retain even more than 30% of its dry strength, while in the dry state, the breaking strength of the paper is improved by approximately 46%. As the demand for more sustainable and resistant paper products continues to grow, the use of wet strength agents is expected to increase in the coming years, as well as the need for research in this field. This research therefore undoubtedly contributes to advancing sustainable practices within the paper industry, aligning with the principles of circular economy by optimizing the utility of recycled fibers while maintaining product quality.

Authors: Wang Guowei , Mehari Ashenafi , Genovese Paolo Vincenzo
Published: April 2024

Under rural revitalization and rapid construction in China, the mismatch between contemporary rural communities and villagers’ space behavior habits has attracted widespread attention. This study proposes and practices a design methodology for a newly built rural community based on spatial elements and their relationship with the behavior of local ancient villages. We explore the relationship between the two by applying drone-tech aerial photos, GPS, and ArcGIS. The results indicate that: (1) Ancient villages have abundant external spatial elements different from urban communities. Each space element of the ancient village has a specific function corresponding to the villagers’ daily life needs. (2) Village space elements are outcomes of the sociocultural process, and their topological structure is not random but follows their use based on hours of the day. (3) About 94.6% of space use behavior in the case of ancient village residents is associated with five space elements. (4) Updating the external spatial elements of ancient villages under the demands of contemporary life makes the application of spatial elements not only continue the villagers’ natural life process, but also satisfy the demands of the contemporary way of life on the external space. This study proposes the characteristics of the relationship between ancient village spatial behavior and external spatial elements through scientific analysis methods, which can provide references for contemporary rural planning and help to solve the mismatch problem between contemporary rural communities and villagers’ behavior habits.

Published: April 2024

At the heart of supply chain innovation lies the challenge of complexity, a pivotal force shaping the pathways to resilience and sustainable success in today’s business environment. Drawing from the resource-based view, dynamic capabilities, and contingency theories, this study examines the impact of green innovation strategies on supply chain resilience through the mediation role of green logistics management practices and the moderation effects of dynamic and structural supply chain complexity. Leveraging a quantitative approach, this study surveyed 404 managers from manufacturing firms in Turkey using a combination of physical and electronic questionnaires. Our analysis robustly supports the interconnected roles of green innovation strategy and logistics management practices in bolstering supply chain resilience. A green innovation strategy significantly enhances green logistics management practices and supply chain resilience. Further, green logistics practices contribute positively to supply chain resilience, acting as a crucial mediator in translating green innovation strategies into heightened supply chain resilience. Additionally, the effectiveness of green innovation strategies in improving green logistics management practices is amplified in less structurally complex supply chains. In contrast, the impact of green logistics practices on supply chain resilience becomes more pronounced in environments with lower dynamic complexity, highlighting the nuanced influence of supply chain complexity on sustainability efforts. The study’s findings contribute a novel perspective to the sustainability discourse, emphasizing complexity’s nuanced role as a determinant of supply chain resilience.
An Assessment of Accessibility from a Socially Sustainable Urban Mobility Approach in Mass Transit Projects: Contributions from the Northern Central American Triangle
Authors: Grande-Ayala Carlos Ernesto
Published: April 2024

This article aims to address the lack of research on the social dimension of sustainability, also known as social sustainability, in urban mobility projects, primarily in cities of the Global South. It proposes a strategy to partially assess social sustainability, focusing on accessibility, which is one of the key dimensions for conducting such an evaluation. To this end, a comparative analysis of three study cases is conducted in the capital cities of the Northern Central American Triangle (NCAT) before and after the construction of bus rapid transit (BRT) projects between 2000 and 2020. Accessibility is evaluated through equity and spatial efficiency indicators obtained through geographical information system (GIS) modeling, including layers representing transportation networks, populated areas, and locations of basic urban facilities. The result is an unprecedented assessment of accessibility in the NCAT capitals, which shows how the Guatemala City BRT project has improved the city’s social sustainability by reducing access times to basic urban facilities, mainly public health clinics and educational facilities, and narrowing the inequality gap as compared to projects in San Salvador and Tegucigalpa, the other capital cities in the NCAT. Additionally, it is emphasized that this methodology can be replicated in the Global South while considering the scarcity of information and the use of open-source software in the process.
Ownership Structure and Financial Sustainability of Saudi Listed Firms
Authors: Alshareef Mohammed Naif
Published: April 2024

This research assesses the impact of ownership structure on financial sustainability. Panel data from 102 Saudi non-financial listed firms covering 2013 to 2022 were analysed using OLS and fixed effects methods. Further, the GMM was employed to check for robustness. The research outcomes reveal the strong and positive effects of institutional ownership and family shareholding on financial sustainability. This positive impact implies that robust and stringent monitoring of family shareholding and institutional investors may neutralise managerial entrenchment, reduce agency costs and pave the way for financial sustainability. However, government ownership appears insignificant, while managerial ownership exerts a strong negative influence on financial sustainability. The negative effect suggests that managerial shareholding may be counterproductive to organisational efficiency. Importantly, the outcomes look consistent using several econometric models. Therefore, the research findings may further shape policymakers’ understanding of how the diverse monitoring strategies of ownership structure influence financial sustainability. Also, the results may serve as an incentive for managers and standard setters to support firms in embracing institutional and family shareholding. The presence of these shareholders may minimise agency conflicts and maximise firm value for sustainable profitability.

Microorganisms, microbiomes, and their products (e.g., enzymes, metabolites, antibiotics, etc.) are key players in the functioning of both natural and anthropized Earth ecosystems; they can be exploited for both research purposes and biotechnological applications, including fighting the big challenges of our era, such as climate change. Culture collections (CCs) and microbial Biological Resource Centres (mBRCs) are repositories of microorganisms that investigate and safeguard biodiversity and facilitate the scientific and industrial communities’ access to microbial strains and related know-how by providing external users with skills and services. Considering this, CCs and mBRCs are pivotal institutions for the valorisation of microorganisms, the safeguarding of life, and the fostering of excellent bioscience. The aim of this review is to present the state-of-the-art of Italian CCs and mBRCs, highlighting strengths, weaknesses, threats, and opportunities. Italy is, indeed, a hotspot of microbial biodiversity with a high rate of endemism and incredible potential, not only for the food and beverage sector (i.e., “Made in Italy” products), where microorganisms can have a beneficial or a spoiling function, but also to guarantee environmental sustainability and foster the bioeconomy through the design of new bioprocesses and products. However, weaknesses, such as the lack of management rules in accordance with international quality standards, are also analysed and ways of overcoming them are discussed. In this context, an overview is given of the Joint Research Unit MIRRI-IT and the European-funded SUS-MIRRI.IT project, which aims to improve the management and sustainability of Italian microbial collections, and serves as a starting point for an innovative revolution in the context of CCs and mBRCs worldwide.

Hepatic encephalopathy (HE) is a serious complication of the hepatobiliary region. One of the main consequences of the pathology is dysfunction of the brain. Diagnosis of this condition can be challenging due to the variety of clinical manifestations and severity. The key to preventing the HE progression and improving the patient’s quality of life is diagnosis in the early stages of the disease. The use of psychometric tests appears promising in determining HE due to their high sensitivity and low cost. It should be noted that results may vary depending on a number of factors, including the age and level of education of the patient. In order to assess the full picture of the disease, it is necessary to conduct an extensive evaluation and combine various examination methods, such as clinical scales, psychometric tests, and computerized tests, to achieve the most accurate diagnosis and determine the severity of HE.

A Cidade da Bahia (Salvador), durante o Setecentos, exerceu função significativa como entreposto comercial transatlântico, principalmente por ser um ponto estratégico de abastecimento de africanos escravizados, destinados aos mercados consumidores dos sertões da América portuguesa. Com isso, é de interesse desta pesquisa compreender o abastecimento do mercado negreiro presente no interior da América portuguesa, buscando entender o processo de redistribuição de escravos a partir dos principais caminhos sertanejos, analisando-a com o olhar especialmente voltado aos mecanismos de operacionalização nesta fase que foi chamada de “terceira perna do tráfico”.

Purpose and Background: There is a difference of opinion among philosophers and sociologists about whether social relationships are based on need or lack of need. This research aims to investigate this issue from the perspective of Imam Ali (AS) in Nahj al-Balagha. Nahj al-Balagheh has dealt more deeply than other religious texts on the lack of need in social relations.Research method: It is a descriptive and analytical method and the discussion is based on the themes of sermons, letters and wisdom of Nahj al-Balagha and related explanations. Findings: Neediness is preferred over need in social relations in Nahj al-Balagha. plus; Self-actualization has been looked at through the lens of needlessness. Conclusion: Although need is a natural thing, but by examining the possibility of lack of need and interpreting self-fulfillment in the light of topics such as contentment and lack of need, we will witness fundamental changes in the hierarchy of needs and the role of each need in human excellence.

Background: This research aimed to investigate the relationship between coping styles, self-esteem, and general health. Methods: The statistical population was female students of Sadeghieh Religious School in Tabriz (200 persons). For sampling random numbers table was used (n=133 by means of Morgan table). For data gathering, three questionnaires were used: Folkman & Lazarus’ ways of coping questionnaire, Cooper Smiths’ self-esteem questionnaire, and Goldberg’s GHQ. Pearson Correlation test and simultaneous multivariate regression were used for analyzing the data. Results: According to the results, there were significant relationships between self-esteem, emotional coping styles, and general health of the students of Sadeghieh Religious School. In addition, self-esteem and emotional coping styles were able to predict general health scores. However, there is no significant relationship between problem-oriented coping styles and students' general health. This variable was not able to predict general health. Conclusion: Reinforcement of the students’ self-esteem and modification of their emotional coping styles were offered for promoting their general health.

Organic farming is one of the main directions of the EU’s farm-to-fork strategy in connection with the European Green Deal. In Poland, organic farming developed dynamically from the accession to the European Union until 2013 and then slowed down. This is a good reason to investigate the conditions affecting the supply side of organic food, especially that the distribution system hardly absorbs the production potential of Polish organic farming. There are few studies with in-depth analysis of relationships between farms and distributors. The research objectives adopted in this paper are the assessment of the intensity of the relations between farmers and organic food distributors. The analysis is based on desk research and the results of a survey of 120 owners of certified organic farms and 120 representatives of shops offering organic products. The results of the analysis show that there are many shops that are supplied by farmers (with a high intensity of relations with farmers) and, at the same time, few farmers selling their products to shops (with a low intensity of relations). Along with the low intensity of farmers’ relations with food processors, this is one of the main barriers to supply development.

El clon criollo de durazno 'Victoria' fue seleccionado en 1984 como la selección S135 en un huerto comercial cultivado en temporal de la parte serrana de Jerez, Zacatecas. Este clon es un árbol vigoroso y productivo. Tiene floración y cosecha tardía de modo que puede reducir los daños por heladas tardías. El periodo de desarrollo del fruto es de 189 días. El fruto de 'Victoria' es casi redondo con pubescencia intermedia; con un peso promedio de fruto de 84 gramos, alto contenido de sólidos solubles y firmeza media comparado con otros genotipos criollos. El color externo e interno del fruto es amarillo. También, se presentan los perfiles de polimorfismo del ácido desoxirribonucleico (ADN) para identificar molecularmente a este cultivar. 'Victoria' es menos preferido por araña roja (Eotetranychus lewisi McGregor), pero susceptible a cenicilla (Sphaeroteca pannosa) y verrucosis (Taphrina deformans). 'Victoria' tiene un requerimiento óptimo estimado de 550 unidades frío (UF). Este clon puede ser cultivado en condiciones de temporal en áreas con un indice precipitación-evaporación mayor al 50 % durante julio y agosto, y una acumulación minima de 500 UF de noviembre a febrero. Las zonas de Chalchihuites y Sombrerete, Zacatecas, México, asi como zonas agroecológicas similares, son áreas apropiadas para la explotación de 'Victoria'.

The mechanisms behind damage to cylindrical shells during inertial convergence are investigated in this article. As solids are subjected to increasing pressures and temperatures during this convergence, they develop a distinct wavy texture on the outer surface, consisting of raised and indented areas. The shape of the protrusions confirms its hydrodynamic origin. The behaviour of the shells is similar to that of cylindrical solid samples in the final stage of convergence.
