Published: August 2022

Modern agriculture is currently enduring rapid changes in defiance of the continuing increase of the global population and the various consequent environmental challenges. Crop quality is becoming as important as crop yield and can be characterized by several parameters. Extensive use of chemical fertilizers leads to food safety concerns globally; hence, the use of mycorrhizal symbionts have proven to be beneficial for the sustainable growth of the agricultural cropping system. Microflora inhabiting the soil entails various ecological interactions which are associated with agricultural performances. Amongst these microflora, mycorrhizal fungi are the critical suppliers of nutrients, with restricted diffusion capacities of minerals such as phosphorus, nitrate, zinc, sulfur etc. Mycorrhizae are the obligatory biotrophs that depend upon their host plant for the nutritional requirements. They act as the key contributors to sustainable agro-ecological enforcement and impact globally on the eco-systemic processes. These soil inhabitants devote themselves to the continuous nutrient flow and extemporize resistance against various environmental stresses like drought, flood, metal toxicity, salinity, etc. This review briefly highlights the taxonomic co-evolution, factors affecting mycorrhizal behaviors (phytohormonal regulation), and the concise mechanistic approach (improved water status, photosystems, stomatal conductance, ionic uptake, C & N fixation) to combat various environmental stresses (biotic/abiotic). Plant growth regulators play a crucial role in this symbiotic establishment with the plant roots. Auxins, brassinosteroids, and strigolactones are responsible for the establishment of mycorrhizal association. On the other hand, ethylene, abscisic acid, and jasmonic acids can promote or downregulate this process in the plants. Whereas, gibberellic acids and salicylic acids negatively impact on mycorrhizal association. The hormonal homeostasis (in response to fungal associations) leads to the activation of transcriptional and signaling cascades which ensues various physio-morphological changes for the benefit of the plant. The role of phytohormones in the regulation of plant-fungus mutualism, and the impact of mycorrhization on the activation of molecular and transcriptional cascades, have been described along with the potential applications of agricultural produce and soil rehabilitation.

Land use and land cover (LULC) changes are a dynamic process determined by natural factors as well as the degree of human interaction in spatial and temporal perspectives. The present study focuses on analysing the LULC changes in the Bhilangana basin post-Tehri dam construction in the Garhwal Himalaya. Landsat series satellite images were used for three time periods to quantify spatial and temporal changes in the LULC using unsupervised classification techniques. The calculations of the areal coverage and change detection were carried out using the ArcGIS 10.3 software. The study finds that LULC changes were observed in the area surrounding the Tehri reservoir. The area under forest cover decreased by 54.71 km2, which is −5.7% of the geographical area, followed by agricultural land by 6.06 km2 (−0.4%) and scrubland and grass cover by 4.23 km2 (−0.28%) during the decade 2000 to 2010. Gradually, due to compensatory afforestation, forest cover increased by 5.65% in the period 2010–2020. A significant relationship with climatic variability is also established with LULC change in the region. The presence of a large water surface at a high altitude modified the albedo and air temperature and increased the atmospheric humidity and precipitation pattern. This study would be vital in understanding the climatic variability in the Himalayas and its impact on the community, environment and climate.

Published: August 2022

This study aimed to find out how the development of sustainability reporting is seen from the theoretical and practical perspectives and how the solutions are solved. This study used a systematic literature review approach. Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method, 24 selected articles were obtained that matched the criteria. The results show that research related to sustainability reporting currently focuses on nine aspects (variables): firm size, profitability, financial leverage, corporate governance structure, ownership structure, firm age, industrial sector, corporate posture, and board qualification and experience. However, from these studies, it was found that there were inconsistencies in the results. Some results showed that a determinant is significant in influencing the company’s sustainability, whereas other studies indicated that the relationship between the two variables was not significant. Research related to sustainability reporting has been carried out jointly in developed and developing countries. However, research focusing on sustainability reporting in developing countries has not been widely carried out; therefore, this study is expected to be a reference for further research on this topic, especially in the decision-making process related to setting priorities in SDG planning and funding allocation. This study focused on companies in developing countries.

Climate change is causing adverse and diverse effects on human beings in term of severe diseases, melting of ice, and increase temperatures, which are directly linked to the consumption of traditional fossil fuels. These fuels can only be replaced by exploring renewable energy technologies, and photovoltaic solar modules are the most promising choice among them. This paper investigates electrical output in term of efficiency and power of a monocrystalline photovoltaic module under climatic conditions of Lahore, Pakistan in an effort to enhance electrical performance based on laminar and turbulent flow boundary conditions. A computational model of a PV module was designed and investigated, when the solar irradiance was observed to be maximum at 920.64 W/m2. Initially, the total flux received and absorbed by PV module was observed to be at 179.37 W/m2 after ray tracing analysis in Trace Pro; thereafter, the module’s temperature increased to 65.86 °C, causing an electrical efficiency drops to 15.65% from 19.40% without applying active cooling schemes. A coupling of Ansys Fluent and Steady State Thermal Analysis was performed for thermal management of a PV module by selecting water and air as a coolant at inlet temperature of 25 °C through microchannels contingent upon varying Reynolds numbers. The results maintained that the optimum coolant outlet temperature (49.86 °C), average PV cell’s layer temperature (32.42 °C), and temperature uniformity (4.16 °C) are achieved by water at 224, 6710, and 4200 Reynolds numbers respectively. In addition, again water maintained 18.65% of electrical efficiency and 33.65 W power output at 6710 Reynolds number. On the other hand, air-based cooling lagged behind water by 14% in term of efficiency and power output at maximum Reynolds number (6710).

Published: August 2022

Due to the COVID-19 pandemic, classes in schools acquired a hybrid learning model. Students took their classes both in person and, at other times, remotely. However, students are currently facing situations that they are not familiar with after a period of two years of confinement due to the COVID-19 pandemic. This emerging model of learning, to which the students had to adapt, not only impacted on their emotions during learning but also influenced their perceptions of their abilities and skills in being able to perform adequately in a situation of uncertainty, which also influenced the degree of academic engagement that they had. This study applied the structural equation modeling technique, using PLS-SEM software, to a sample of 194 students. The results show that their self-efficacy to act in a situation of vulnerability was affected, which is why their negative emotions increased and their positive emotions decreased. This in turn influenced the degree of engagement and effort they invested in developing a school activity.

Published: August 2022

Agriculture and allied sectors are the mainstays of the Indian rural population and yet, the vast majority is still poor. The Indian government has introduced pro-farmer schemes and policies for their quality of life, but the improvement rate of their quality of life is still relatively slow. In this context, this paper presents a sustainable agricultural business model (SABM), which defines contexts, practices, and outcomes. This SABM is compared with the conventional agricultural business model (CABM). Innovative farmers were selected from different parts of India. Their practices are examined with key performance indicators (KPIs) regarding strategic focus, labor productivity, vital resources usage, soil maintenance, output quality, and revenue performance. Case study results suggest that farmers that adopt SABM are innovative and productive with a better quality of life. In contrast, those who follow CABM are characterized by relatively low productivity and continuous hardships. Lessons and implications, along with future study topics, are discussed.

Crisis Management for Sustainable Corporate Value: Finding a Construal Fit between Social Distance, Crisis Response, and Crisis Severity
Authors: Oh Hyun Jee , Kim Jeesun , Ham Chang-Dae
Published: August 2022

Despite growing research on public attributions of crisis responsibility, little is known about the role of perceived social distance to organizations in conjunction with crisis severity and crisis response strategies. Applying construal level theory (CLT) to the crisis communication context, we examined the role of the construal fit between social distance, crisis severity, and crisis response strategy in determining crisis responsibility, negative word-of-mouth (WOM) intentions, and anger. A two (social distance to a crisis: close vs. distant) × two (crisis response strategy: defensive vs. accommodating) × two (crisis severity: low vs. high) between-subjects experiment revealed two interaction effects: (1) the interaction effect of social distance and crisis response strategy on anger and negative WOM and (2) the interaction effect of social distance and crisis severity on negative WOM. No interaction effects emerged with respect to crisis responsibility. We discuss the theoretical contribution of this study’s results—namely, how social distance to a crisis impacts public reactions to crisis response strategies. We also outline the practical implications for achieving a better construal fit between social distance and crisis response strategy for effective crisis communication, which may serve as an opportunity for sustainable corporate management.

Published: August 2022

With the accelerated evolution of the digital transformation of economic activities, the digitalization of the different parts of the value chain, such as manufacturing, marketing, and management, has increased significantly, thereby changing the form of organizational production management while affecting how corporate social responsibility (CSR) is achieved. Therefore, in this study, we examined the relationship between the digital transformation of value chains and CSR performance and the moderating role of property ownership and market dependence. The results show that the digital transformation of value chains can improve CSR performance. When the three types of digital transformation are conducted at the same time, compared with digital manufacturing transformation and digital marketing transformation, digital management transformation has a greater impact on CSR performance. Non-state-owned enterprises and enterprises with higher market dependency show greater improvement in their CSR performance than state-owned enterprises and enterprises with lower market dependency as a result of the digital transformation of value chains. Furthermore, we found a certain degree of value mismatch between the digital transformation of the different value chain links of enterprises and the different dimensions of social responsibility. Specifically, the digital transformations of manufacturing, marketing, and management activities only exert a significant impact on shareholder responsibility, public responsibility, and shareholder and employee responsibility, respectively. This result indicates that the digital transformation of the entire value chain needs to be further optimized and integrated to achieve social responsibility values that match the value chain. This study not only helps enterprises identify the shortcomings in the digital transformation of the value chain but also provides development ideas for enterprises to realize the two-wheel drive of business value and social value through the digital transformation of the whole value chain.
Utilizing Language Models to Expand Vision-Based Commonsense Knowledge Graphs
Authors: Rezaei Navid , Reformat Marek Z.
Published: August 2022

The introduction and ever-growing size of the transformer deep-learning architecture have had a tremendous impact not only in the field of natural language processing but also in other fields. The transformer-based language models have contributed to a renewed interest in commonsense knowledge due to the abilities of deep learning models. Recent literature has focused on analyzing commonsense embedded within the pre-trained parameters of these models and embedding missing commonsense using knowledge graphs and fine-tuning. We base our current work on the empirically proven language understanding of very large transformer-based language models to expand a limited commonsense knowledge graph, initially generated only on visual data. The few-shot-prompted pre-trained language models can learn the context of an initial knowledge graph with less bias than language models fine-tuned on a large initial corpus. It is also shown that these models can offer new concepts that are added to the vision-based knowledge graph. This two-step approach of vision mining and language model prompts results in the auto-generation of a commonsense knowledge graph well equipped with physical commonsense, which is human commonsense gained by interacting with the physical world. To prompt the language models, we adapted the chain-of-thought method of prompting. To the best of our knowledge, it is a novel contribution to the domain of the generation of commonsense knowledge, which can result in a five-fold cost reduction compared to the state-of-the-art. Another contribution is assigning fuzzy linguistic terms to the generated triples. The process is end to end in the context of knowledge graphs. It means the triples are verbalized to natural language, and after being processed, the results are converted back to triples and added to the commonsense knowledge graph.

Published: August 2022

Current research is focused on the utilization of a numerical solution of Casson cobalt ferrite nanofluid flow by taking two forms of base fluid. This investigation includes the gradual influence of nonlinear thermal radiation on the improvement of heat transfer related to the flow of nanofluids over a stretched rotating surface by the Darcy–Forchheimer law. The model constructed by a Casson nanoliquid in the boundary layer’s flow is studied for its symmetric behaviour, including cobalt ferrite nanomaterials. Two base liquids named as ethylene glycol and water are considered. The rate of heat transport is examined by considering Newtonian heating conditions. By utilizing similarity transformations, a partial differential system that governs the said model has been transformed into a highly nonlinear ordinary differential system, and numerical outcomes are obtained by implementing the RK4 via shooting methodologies. All obtained results, including local skin friction coefficients and local Nusselt number, are defined and discussed in the paper. The study’s findings ensure that the Casson cobalt ferrite nanofluid flowing towards a stretching plate has a unique solution: A variation of the solid volume fraction corresponds to the decrease in various values of the Casson nanofluid parameter for both type of nanofluid. Furthermore, a similar behaviour is noted for various values of the solid volume fraction, which corresponds to various values of the inertia coefficient parameter. Moreover, for the highest values of the solid volume fraction and all values of R1 and Ni taken into account, the rate of heat transfer upsurges. The data from the local skin friction coefficient (LSFC) and local Nusselt number (LNN) have been analysed using various statistical distributions, and it has been determined that both datasets generally fit the exponentiated Weibull distribution for various values of considered parameters. The findings would serve as a starting point for the manufacture of devices.
Two-Dimensional Car-Following Control Strategy for Electric Vehicle Based on MPC and DQN
Authors: Zhang Sheng , Zhuan Xiangtao
Published: August 2022

For the coupling problem of longitudinal control and lateral control of vehicles, a two-dimensional (2-D) car-following control strategy for an electric vehicle is proposed in this paper. First, a 2-D car-following model for longitudinal following and lateral lane keeping is established. Then, a 2-D car-following control strategy is designed, and the longitudinal following control and lateral lane keeping control are integrated into one model predictive control (MPC) framework. The 2-D car-following strategy can realize the multi-objective coordinated optimization for longitudinal control and lateral control during the 2-D car-following process, and the multiple objectives are: safety, tracking, comfort, lane keeping, lateral stability and economy. In addition, the economy is important for electric vehicles. The weight matrix of the objective function in the MPC framework is symmetric, and the weight coefficients for the weight matrix have a great influence on the control. The contribution of this paper is: in order to adapt to different dynamic processes of lane keeping, the weight coefficients in the MPC framework are optimized in real-time based on the deep Q network (DQN) algorithm. Finally, to verify the 2-D car-following control strategy, a comparison strategy and two experimental scenarios are set, and simulation experiments are carried out. In scenario 1, compared with the comparison strategy, the lane keeping, lateral stability and economy of the proposed strategy are improved by 37.21%, 17.57% and 9.26%, respectively. In scenario 2, compared with the comparison strategy, the lane keeping, lateral stability and economy of the proposed strategy are improved by 36.45%, 16.66% and 18.52%, respectively. Therefore, compared with the comparison strategy, the 2-D car-following control strategy can have better lane keeping, lateral stability and economy on the premise of ensuring other performances during the 2-D car-following process.

Venoms from venomous arthropods, including bees, typically induce an immediate local inflammatory response; however, how venoms acutely elicit inflammatory response and which components induce an inflammatory response remain unknown. Moreover, the presence of superoxide dismutase (SOD3) in venom and its functional link to the acute inflammatory response has not been determined to date. Here, we confirmed that SOD3 in bee venom (bvSOD3) acts as an inducer of H2O2 production to promote acute inflammatory responses. In mouse models, exogenous bvSOD3 rapidly induced H2O2 overproduction through superoxides that are endogenously produced by melittin and phospholipase A2, which then upregulated caspase-1 activation and proinflammatory molecule secretion and promoted an acute inflammatory response. We also showed that the relatively severe noxious effect of bvSOD3 elevated a type 2 immune response and bvSOD3 immunization protected against venom-induced inflammation. Our findings provide a novel view of the mechanism underlying bee venom-induced acute inflammation and offer a new approach to therapeutic treatments for bee envenoming and bee venom preparations for venom therapy/immunotherapy.

A safe and efficacious live-attenuated vaccine for porcine epidemic diarrhea virus (PEDV) is not commercially available in the United States yet. Two major PEDV strains are currently circulating in US swine: highly virulent non-S-INDEL strain and milder virulent S-INDEL strain. In this study, the safety and protective efficacy of a plaque-purified S-INDEL PEDV isolate formulated as a vaccine candidate was evaluated. Ten pregnant gilts were divided into three groups and orally inoculated at 79 days of gestation and then boosted at 100 days gestation (T01: n = 4, vaccination/challenge; T02: n = 4, non-vaccination/challenge; T03: n = 2, non-vaccination/non-challenge). None of the gilts had adverse clinical signs after vaccination. Only one T01 gilt (#5026) had viral replication and detectible viral RNA in feces. The same gilt had consistent levels of PEDV-specific IgG and IgA antibodies in serum and colostrum/milk. Farrowed piglets at 3 to 5 days of age from T01 and T02 gilts were orally challenged with 103 TCID50/pig of the virulent non-S-INDEL PEDV while T03 piglets were orally inoculated with virus-negative medium. T01 litters had overall lower mortality than T02 (T01 36.4% vs. T02 74.4%). Specifically, there was 0% litter mortality from T01 gilt 5026. Overall, it appears that vaccination of pregnant gilts with S-INDEL PEDV can passively protect piglets if there is virus replication and immune response induction in the pregnant gilts.

B-cell lymphoma is a group of malignant proliferative diseases originating from lymphoid tissue with different clinical manifestations and biological characteristics. It can occur in any part of the body, accounting for more than 80% of all lymphomas. The present study aimed to construct bispecific single-domain antibodies against CD20 and CD3 and to evaluate their function in killing tumor cells in vitro. A Bactrian camel was immunized with a human CD20 extracellular peptide, and the VHH gene was cloned and ligated into a phagemid vector to construct the phage antibody display library. A phage antibody library with a size of 1.2 × 108 was successfully constructed, and the VHH gene insertion rate was 91.7%. Ninety-two individual clones were randomly picked and screened by phage ELISA. Six strains with the high binding ability to human CD20 were named 11, 30, 71, 72, 83, and 92, and induced expression and purification were performed to obtain soluble CD20 single-domain antibodies. The obtained single-domain antibodies could specifically bind to human CD20 polypeptide and cell surface-expressed CD20 molecules in ELISA, Western blot, and cell immunofluorescence assays. The anti-CD20/CD3 bispecific nanobody (BsNb) was successfully constructed by fusing the anti-CD20 VHH gene with the anti-CD3 VHH and the bispecific single-domain antibody was expressed, purified, and validated. Anti-CD20/CD3 BsNb can specifically bind CD20 molecules on the surface of human lymphoma Raji cells and CD3 molecules on the surface of T cells in flow cytometry analysis and effectively mediate peripheral blood mononuclear cells (PBMCs) target Raji cells with a killing efficiency of up to 30.4%, as measured by the lactate dehydrogenase (LDH) method. The release of hIFN-γ from PBMCs during incubation with anti-CD20/CD3 BsNb was significantly higher than that of the control group (p < 0.01). The anti-CD20/CD3 BsNb could maintain 80% binding activity after incubation with human serum at 37 °C for 48 h. These results indicated the strong antitumor effect of the constructed anti-CD20/CD3 BsNb and laid the foundation for the further development of antitumor agents and the clinical application of anti-CD20/CD3 BsNb.
Determination of Endangered Freshwater Fishes: Can Value Be Estimated?
Authors: Stauffer Jay Richard , Morgan Raymond Paul
Published: August 2022

The determination of endangered species is problematic. If one considers a species to be ontological individuals, then if a species goes extinct, it is gone forever. The Brook Trout is used as an example of a “species” which may be comprised of several unique entities that warrant a specific status. In addition to determining the specific status, it is difficult to determine how to place a monetary value on endangered species that do not have a general appeal to the public (e.g., many bird species), a commercial value, no known medical properties (e.g., deep water sponges vs. cancer), or generate monies for recreation. Perhaps if we could identify the unique information carried by a particular species, we could place a value on that information and assess the monetary value of the information lost.
Climate Adaptation Needs to Reduce Water Scarcity Vulnerability in the Tagus River Basin
Authors: Sondermann Melissa Nogueira , de Oliveira Rodrigo Proença
Published: August 2022

In southern Europe, climate change is expected to aggravate water scarcity conditions and challenge current water management practices. The present paper evaluates the impacts of climate change in the highly regulated Tagus River basin and assesses various adaptation options, quantifying the effort needed to maintain the ability to sustain current water uses. A water management and allocation model covering surface and groundwater resources is used to evaluate available and renewable water resources for different climate scenarios. Additionally, the Water Exploitation Index Plus (WEI+) and water supply reliability criteria are used to quantify water scarcity and the ability to satisfy water demands, respectively. The results show that climate change will significantly change the stream flow regime and reduce water availability in the Tagus River basin, but the existing reservoir infrastructure will alleviate some of these impacts, especially in the dry half-year. Until the end of the century, water scarcity levels, measured by annual WEI+, are expected to increase in the Tagus River basin from 0.46 to 0.52 or 0.62, respectively under two Representative Concentration Pathways (RCP 4.5 or RCP 8.5). The benefits of streamflow regulation vary with the hydrological regimen, the current degree of water use and the role of groundwater resources to meet demand. The benefits of streamflow regulation are also dependent on the environmental flow requirements that will be adopted in the future. A reduction of water consumption for irrigation by 25% to 40% will significantly improve the Tagus River system performance and maintain the current scarcity situation in the future, under the expected scenarios of climate change.
Estimation of Boundary Shear Stress Distribution in a Trapezoidal Cross-Section Channel with Composite Roughness
Authors: Luo You , Zhu Senlin , Yang Fan , Gao Wenxiang , Yan Caiming , Yan Rencong
Published: August 2022

The estimation of boundary shear stress distribution in a channel is a challenge in some hydraulic or environment investigations. A new partition model of a trapezoidal cross-section in a prismatic channel with composite roughness has been introduced based on a concept of a standardized cross-section using the “zero-shear stress” division lines. Based on this new model, an “equal local-region velocity” assumption, which can be regarded as an improvement of Einstein’s (1942) “equal velocity” assumption, has been proposed that is based on a discussion on the mechanism of energy transfer and velocity distribution at two sides of a dividing line. This assumption along with some empirical treatments have been employed to establish a new method to estimate the boundary shear stress of a side-wall or bed. Comparisons show that the proposed method can be applied to composite roughness cases and provides better prediction performance compared to other methods.
