Blue carbon has made significant contributions to climate change adaptation and mitigation while assisting in achieving co-benefits such as aquaculture development and coastal restoration, winning international recognition. Climate change mitigation and co-benefits from blue carbon ecosystems are highlighted in the recent Intergovernmental Panel on Climate Change Special Report on Ocean and Cryosphere in a Changing Climate. Its diverse nature has resulted in unprecedented collaboration across disciplines, with conservationists, academics, and politicians working together to achieve common goals such as climate change mitigation and adaptation, which need proper policy regulations, funding, and multi-prong and multi-dimensional strategies to deal with. An overview of blue carbon habitats such as seagrass beds, mangrove forests, and salt marshes, the critical role of blue carbon ecosystems in mitigating plastic/micro-plastic pollution, as well as the utilization of the above-mentioned blue carbon resources for biofuel production, are critically presented in this research. It also highlights the concerns about blue carbon habitats. Identifying and addressing these issues might help preserve and enhance the ocean’s ability to store carbon and combat climate change and mitigate plastic/micro-plastic pollution. Checking out their role in carbon sequestration and how they act as the major carbon sinks of the world are integral parts of this study. In light of the global frameworks for blue carbon and the inclusion of microalgae in blue carbon, blue carbon ecosystems must be protected and restored as part of carbon stock conservation efforts and the mitigation of plastic/micro-plastic pollution. When compared to the ecosystem services offered by terrestrial ecosystems, the ecosystem services provided by coastal ecosystems, such as the sequestration of carbon, the production of biofuels, and the remediation of pollution, among other things, are enormous. The primary purpose of this research is to bring awareness to the extensive range of beneficial effects that can be traced back to ecosystems found in coastal environments.
Optimization of the Granular Mixture of Natural Rammed Earth Using Compressible Packing Model
Authors: Dialmy Atar , Rguig Mustapha , Meliani Mehdi
Published: February 2023

Rammed earth (RE) construction is an ancestral technique that allows for the building of durable and resistant constructions. RE buildings are sustainable and environment-friendly, and ensure energy optimization during the construction cycle. For these reasons, many of the following RE characteristics are studied: mechanical strength, seismic resistance, and thermal performance. However, the mix design of RE soils has been rarely studied. There is practically no scientific approach that allows for defining precise dosages of clay, silt, sand, and gravel used in RE materials. The broader aim of this article is to determine a scientific mix design method to find an optimal RE granular mixture. The compressible packing model (CPM) is applied to study the effect of every granular class on compactness and define the optimum mixture. Many tests have been conducted such as the Modified Proctor, compression test, and ultrasonic velocity pulse test to evaluate the relevance of this model. The results suggest many granular corrections for RE material that considerably enhance compactness and unconfined compressive strength (UCS). It was found that one granular correction provides a 137% increase in the initial UCS. Therefore, this approach enables the defining of which granular class is to be added or reduced to optimize the mechanical properties of RE.

Published: February 2023

Digital knowledge and information have become significant production variables that have permeated all aspects of life and play a leading and supporting role in the growth of the real economy as the digital economy has developed. Through field research and web research, this study identifies digital-economy-related enterprises as the survey object; summarizes the fundamental information for these enterprises, their level of digitization, and the dilemma and demands of digital-level advancement; and generates survey data for 1936 enterprises. On the basis of these data, this study extracts the elements that influence the improvement of the enterprises’ digital level, applies statistical knowledge and machine learning techniques, and derives an enterprise digitization level index system and associated index score for enterprise digitization level. The experimental results indicate that the region, the time of establishment, the nature of ownership, the number of employees, R&D investment, being a national high-tech enterprise, and the establishment of digital transformation management departments have major effects. The AUC value of the XGBoost model modeled using all feature variables has achieved certain results, and the five assessment indices of the model have been enhanced to varying degrees, with the AUC being 0.9263.
Research on Deformation and Failure Law of the Gob-Side Roadway in Close Extra-Thick Coal Seams

Published: February 2023

To reveal the deformation and failure law of the gob-side roadway (GSR) and the main influencing factors in close extra-thick coal seams, the research methods of field monitoring, theoretical analysis, and numerical simulation are adopted in this paper. Field monitoring data shows that microseismic events occur and accumulate frequently in the surrounding rock and some overlying key layers of the GSR. Large deformation is experienced in the middle part of roadway near the solid coal side, the middle and upper parts of the roadway near the coal pillar side, and the roadway floor. The overlying strata of the GSR are fractured to form a composite structure as “low-level cantilever beam and high-level masonry beam”. The coal pillar is squeezed and effected by the composite beam structure and the rotation moment M, causing serious bulge in middle and upper part of the coal pillar side. The stability of the solid coal side of the roadway is affected by the stress transferred from gangue contact point. Numerical simulation shows that the immediate roof and key layer breakage are induced by the mining of the 30,501 working face. Shear and tension failures happen in the GSR due to overburden subsidence and rotary extrusion. The stress and displacement at the middle and upper of the roadway on the coal pillar side are larger than the other area. Compared with the solid coal side, the coal on the coal pillar side is obviously more fractured, with a lower bearing capacity. The peak stress in the coal pillar shows up 2 m away from the roadway, which is close to the length of bolt support. The mining-induced stress and the stress transferred from gangue contact point are the direct reasons for solid coal bulge beside the roadway. The peak stress on the solid coal side is located 7 m away from the roadway, at the gangue contact point where overburden fractures. The overburden strata loads and the transferred stress near the gangue contact point are transferred from the sides to the roadway floor. Their coupling effect with the in situ horizontal stress acts as the force source for the plastic floor heave.
Strategies for Environmental Protection and Optimization of Ecological Business Economic Growth from the Perspective of Sustainable Development
Authors: Ma Li , Liu Xuefeng
Published: February 2023

The concept of ecological commercial economy refers to the use of ecological economics principles and system engineering methods to change production and consumption patterns within the scope of the carrying capacity of the ecosystem in order to tap into all of the available resource potential. It develops some economically developed and ecologically efficient industries and builds a culture with reasonable systems, a harmonious society, and a healthy ecological environment. This paper aims to use deep learning algorithms to study environmental protection and the optimization of ecological business economic growth from the perspective of sustainable development. In this regard, this paper proposes a theoretical model of environmental regulation, which aids in the study of the sustainable development of the ecological economy. Through experimental analysis, this study determined that the non-renewable resources of the two cities designated M and N dropped from 82% and 99% in 2017 to 78% and 79% in 2021, a decrease of 3% and 20%, respectively. This shows that the non-renewable resources of the four cities in area A generally showed a downward trend. The experimental results show that the deep learning theory and the environmental regulation model play a specific and effective role in the researching of the ecological business economy.
Experimental and Finite Element Study on the Shear Performance of Existing Super-Span Concrete T-Beams Retrofitted with Glass Fiber-Reinforced Plastic
Authors: Hou Dongxu , Hu Tieming , Zhang Guanhua
Published: February 2023

Super-span, reinforced concrete, T-shaped cross-section beams (T-beams) with a service life of more than 30 years are widely used in highway bridges in China. Most of these beams have been retrofitted with glass fiber-reinforced plastic (GFRP) to prevent performance degradation. However, the actual shear performance, ultimate state, and failure mechanism of the existing retrofitted super-span concrete T-beams are currently unclear for many inextricable problems. To fill these gaps, in this study, one super-span concrete T-beam, in service for 31 years and retrofitted with GFRP, was extracted from a highway bridge to conduct shear experimentation in a structural laboratory. To assess the particularity of the specimen, finite element analysis was also conducted using ABAQUS software as a supplement to the shear tests. The failure procedure of the specimen was investigated, and the influence of the loading mode on the shear performance of a super-long and old T-beam was also studied. It is concluded that the failure of the super-span T-beam begins with small cracks at the bottom of the mid-span, rather than a loading point.

Published: February 2023

Pairs of lepton and antilepton (dilepton) in a continuous mass range are one of the most experimentally challenging and golden probes of the quark-gluon plasma (QGP) produced in heavy ion collisions because they do not strongly interact with the hot and dense medium, and reflect the properties of the medium at the time the dilepton is generated. The measurements of dileptons require lepton identification with high purity and high efficiency at large detector acceptance. STAR is one of two large experiments at the relativistic heavy ion collider with a primary goal of searching for the QGP and studying its properties. The STAR experiment launched a comprehensive dielectron (e+e−) program enabled by the time-of-flight (TOF) detector that had been fully installed in 2010. In this article, we review the decade-long R&D, the construction and performance of the STAR TOF detector, and dielectron measurements, including thermal dielectron production and dielectron production from the Breit–Wheeler process. Future perspectives are also discussed.
Prediction of Shrinkage Behavior of Stretch Fabrics Using Machine-Learning Based Artificial Neural Network
Authors: Ahirwar Meenakshi , Behera B. K.
Published: February 2023

Stretch fabric provides good formability and does not restrict the movement of the body for increased tension levels. The major expectations of a wearer in an apparel fabric are a high level of mechanical comfort and good aesthetics. The prediction of shrinkage in stretch fabric is a very complex and unexplored topic. There are no existing formulas that can effectively predict the shrinkage of stretch fabrics. The purpose of this paper is to develop a novel model based on an artificial neural network to predict the shrinkage of stretch fabrics. Different stretch fabrics (core-spun lycra yarn) with stretch in the weft direction were manufactured in the industry using a miniature weaving machine. A model was built using an artificial neural network method, including training of the data set, followed by testing of the model on the test data set. The correlation of factors, such as warp count, weft count, greige PPI, greige EPI, and greige width, was established with respect to boil-off width.

Published: February 2023

Pig health is impaired and growth performance is reduced when exposed to deoxynivalenol (DON). The measurement of DON in individual feedstuffs and complete swine diets is variable because of the inconsistent distribution of mycotoxins in feed and the difficulties in obtaining representative samples. We investigated whether measuring DON and its metabolites in biological samples could be used as a predictor of DON ingestion by pigs. Blood samples were collected between 3 and 4 h after the morning meal and urine samples were quantitatively collected over a 24 h period on d 40 and 82 of the study to evaluate serum and urinary content of DON and DON metabolites (iso-deoxynivalenol, DON-3-glucuronide, DON-15-glcurunide, deepoxy-deoxynivalenol, iso-deepoxy-deoxynivalenol, deepoxy-deoxynivalenol-3-glucuronide, and deepoxy-deoxynivalenol-15-glucuronide). The intake of DON was positively correlated with urinary DON output. Similarly, there was an increase in serum DON level with increasing DON intake. Overall, it was found that DON intake correlated with DON concentration in urine and blood serum when samples were collected under controlled conditions. Analyzing DON levels in urine and blood serum could be used to predict a pig’s DON intake.

Of the 12 million people who inject drugs worldwide, 13% live with HIV. Whether opioid use impacts HIV pathogenesis and latency is an outstanding question. To gain insight into whether opioid use influences the proviral landscape and latent HIV reservoir, we performed intact proviral DNA assays (IPDA) on peripheral blood mononuclear cells (PBMCs) from antiretroviral therapy (ART)-suppressed people living with HIV (PWH) with or without current opioid use. No differences were observed between PWH with and without opioid use in the frequency of HIV intact and defective proviral genomes. To evaluate the latent reservoir, we activated PBMCs from ART-suppressed PWH with or without opioid use and assessed the induction of HIV RNA. PWH using opioids had diminished responses to ex vivo HIV reactivation, suggesting a smaller reversible reservoir of HIV-1 latently infected cells. However, in vitro studies using primary CD4+ T cells treated with morphine showed no effect of opioids on HIV-1 infection, replication or latency establishment. The discrepancy in our results from in vitro and clinical samples suggests that while opioids may not directly impact HIV replication, latency and reactivation in CD4+ T cells, opioid use may indirectly shape the HIV reservoir in vivo by modulating general immune functions.

Published: February 2023

Different blood gas analyzers are used in equine practice. Every machine needs to be validated, as they have not been designed for use in horses. The aim of this study was to compare the newly marketed GEM5000 machine to the formerly validated epoc machine for blood gas analysis in horses. In this prospective, non-blinded, comparative laboratory analyzer study, 43 equine blood samples were analyzed on both analyzers and values were compared between the two machines via Lin’s concordance analysis, Passing–Bablok regression analysis and Bland–Altman plots. Duplicate measurements were conducted on the GEM5000 machine to evaluate precision. The GEM5000 failed to achieve the required precision for tHb, Hct and iCa2+, but achieved acceptable precision for all other parameters. Concordance correlation analysis revealed poor correlation for Na+, Cl−, iCa2+, K+, Hct and tHb, while there was an at least moderate agreement for all other parameters. Passing–Bablok regression revealed significant constant bias for pCO2, pO2, Cl−, and iCa2+ and significant proportional bias for pCO2, iCa2+ and SO2. Bland–Altman analysis revealed significant systematic bias for Na+, Cl−, iCa2+, K+, Hct, tHb and SO2. This study shows that while precision of the GEM5000 is good, values should not be used interchangeably with data obtained from other blood gas analyzers.

Published: February 2023

As an important tool for the development and utilization of river water conservancy and hydropower resources, cascade reservoirs will directly affect human life and ecological environment. Therefore, how to sustainably and rationally dispatch the water resources of cascade reservoirs is of great importance to human society and ecological environment. In order to solve this problem, this paper constructs the objective function by considering the three goals of reservoir power generation target, social benefit and ecological benefit. On this basis, a mathematical model of cascade reservoir scheduling is established considering multi-dimensional constraints such as water transmission and water supply capacity constraints, water level constraints and flow constraints. In addition, we consider the fact that the crow search algorithm (CSA) is easy to fall into as the local optimal solution due to the influence of its flight distance parameters on the search ability when solving large-scale optimization problems. Therefore, a crow search algorithm based on particle swarm optimization (PSO-CSA) is designed to solve the multi-objective scheduling model of cascade reservoir established in this paper. Finally, this paper compares the PSO-CSA algorithm, PSO algorithm, CSA algorithm and genetic algorithm (GA) which is widely used in reservoir water resource dispatch, through a simulation example. The simulation results show the superiority of the algorithm designed in this paper in solving the water resource control problem of cascade reservoirs.
Analysis and Prediction of Poyang Lake’s Navigable Conditions under a New Hydrological Regime
Authors: Wang Dong , Zhou Tao
Published: February 2023

Human activities have profoundly changed the hydrological regime and trends of rivers and lakes, which, in turn, has affected the utilization of their navigable conditions. However, few studies have focused on the effects of changes in hydrological regimes and trends of rivers and lakes on navigable conditions. Thus, this study intensively analyzes and investigates the navigable depth at the major control sections in the lake area during the dry season in the period before 2002, when the Three Gorges Reservoir was not yet constructed, and the period from 2003 to 2019, when the Three Gorges Project was put into operation with impoundment based on the dry-season water level curve in the Poyang Lake area since the operation of the Three Gorges Reservoir. This study also further analyzes the influence of the change in the hydrological regime on the navigable depth in the lake area. The results show that the waterway depth and width could meet the navigation requirements before 2002. From 2003 to 2019, whereas the water level with a 98% guarantee rate of duration at the Xingzi Hydrometric Station decreased, that at the Hukou Hydrometric Station increased. The waterway depth and width at both the Hukou and Xingzi hydrometric stations could meet the requirements of the size of Grade II waterways. This study also performs a simulation prediction of the water regime of Poyang Lake under a new hydrological regime using the mathematical model of water and sediment of the Changjiang River Scientific Research Institute. The results reveal that in 2030 and 2050, after the Three Gorges Reservoir has been in operation for 30–50 years, the water levels at the Hukou, Xingzi, and Wucheng hydrometric stations (Hukou) of Poyang Lake will decline by approximately 0.18–0.66 and 0.10–0.24 m, respectively. Although the overall navigable depth can basically meet the navigation requirements for a period of time, the trend of the long-term declining water level may cause unsafe navigation risks.
Assessment of the Potential Hydrological Impacts of Climate Change in Quebec—Canada, a Refined Neutral Approach
Authors: Valencia Giraldo Marinela del Carmen , Ricard Simon , Anctil François
Published: February 2023

There is currently much discussion as to whether probabilistic (top–down) or possibilistic (bottom–up) approaches are the most appropriate to estimate potential future climate impacts. In a context of deep uncertainty, such as future climate, bottom-up approaches aimed at assessing the sensitivity and vulnerability of systems to changes in climate variables have been gaining ground. A refined framework is proposed here (in terms of coherence, structure, uncertainty, and results analysis) that adopts the scenario–neutral method of the bottom–up approach, but also draws on some elements of the top–down approach. What better guides the task of assessing the potential hydroclimatological impacts of changing climatic conditions in terms of the sensitivity of the systems, differential analysis of climatic stressors, paths of change, and categorized response of the scenarios: past, changing, compensatory, and critical condition. The results revealed a regional behavior (of hydroclimatology, annual water balances, and snow) and a differential behavior (of low flows). We find, among others, the plausible scenario in which increases in temperature and precipitation would generate the same current mean annual flows, with a reduction of half of the snow, a decrease in low flows (significant, but differentiated between basins), and a generalized increase in dry events.

Relevance. Odontogenic cysts in children are the most common bone pathology. The study aimed to conduct a retrospective descriptive analysis of inflammatory odontogenic cysts cases associated with primary teeth in children.Material and methods. The study analysed the medical records of children diagnosed with "radicular cyst associated with a primary tooth" from 2015-2020. We studied the following characteristics, namely, sex, age, location of the process, condition of the teeth in question, surgical treatment techniques and outcome. The data obtained were processed by methods of variational statistics. The Student t-test assessed the significance of differences.Results. The study analysed 60 cases of inflammatory odontogenic cysts in children aged 6 to 13 years. Cysts were more often associated with the primary lower second molars previously treated with the resorcinol-formaldehyde resin therapy. The period from the tooth treatment to the cyst diagnosis was 3 to 5 years. The treatment of cysts applied methods of a gentle and traditional cystotomy. Fifty-one children (85.0%) had follow-up examinations. All children showed bone tissue restoration during the period of 4 to 12 months and spontaneous eruption of permanent teeth in 3-8 months. Only 4 cases (7.8%) required orthodontic correction of permanent teeth position.Conclusion. Primary lower molars, previously treated with resorcinol-formaldehyde resin, are the most common cause of jaw inflammatory odontogenic cysts in children. Low-traumatic surgical methods preserving the follicles of permanent teeth are highly effective (88.2%).
Institutionalization, Organizational Commitment, and Hope for Personal Fulfillment in The Shawshank Redemption
Authors: Lin Chia-Li , Wang Ya-huei
Published: February 2023

Institutionalization is a socialization process through which the values, beliefs, policies, and practices of an organization are instilled within the members of that organization that they might collectively adopt these values or rules and commit themselves to that organization. However, those being institutionalized under authoritarian discipline may lose the freedom of their soul and a personal level of self. In order to raise readers’ awareness of the impact of institutionalization and commitment on the individual or collective actors, this study intends to use the film The Shawshank Redemption as a case study, using content analysis as a qualitative research technique to analyze the symbolic scenes in the film in order to reveal how commitment and stability via institutionalization can be brought into the organization. To achieve this goal, the study uses Scott’s institutional theory and Meyer and Allen’s organizational commitment model to demonstrate how commitment may greatly impact people. Those being institutionalized, like Brooks in The Shawshank Redemption, may lose their ability to think and act independently and thus lose their hope for fulfillment. However, those like Andy and, later, Red, choosing to hold on to freedom of the soul and a personal level of self, can deinstitutionalize themselves; break free of the shackles, either physically or spiritually, of the organization; and make a commitment toward their own inner development.

Published: February 2023

My professional practice area is as a lecturer in business education at Otago Polytechnic, Dunedin, New Zealand. I am also a neurodivergent learner who has observed and experienced several challenges that learners like myself face, not the least of which is a lack of awareness and practical strategies among tertiary lecturers. I believe there is an important professional practice challenge that needs to be addressed. Therefore, I am undertaking this project to explore how tertiary lecturers can create learning experiences that address the challenges faced by neurodiverse learners and utilise and enhance the capabilities they bring to their learning journey. As part of the research phase, thirteen participants took part in a semi-structured interview, five learners, six lecturers, and two experts. From the responses I collected from each group of participants (appendix 3), I identified four clear themes that were subsequently analysed based on the responses. As a result of this study, I have developed some tools and strategies designed to aid learners, lecturers, and support staff in their educational journey. As an outcome of my project, I aim to make explicit the challenges that neurodiverse learners face and to provide practical strategies for lecturers to enhance learner success. The intended output of my project will be a set of guidelines for both neurodiverse learners and lecturers. This project is an essential step in my professional journey towards becoming a specialist lecturer and advocate for neurodiverse learners.

In this study, carbon dots (CDs) were synthesized via microwave, using precursor banana peel extract from different cities (Maceió and Aracaju) to evaluate their optical and structural properties. In addition, the volumes of the extract were varied for laboratory scale-up tests. DLS analyses showed that the most significant size frequencies for all CDs were less than 10 nm. UV-Vis and FTIR absorption spectra indicated the presence of aromatic groups and heteroatoms. In addition, the CDs showed excitation wavelength-dependent emission, with maximum intensities at 457 nm. The results indicate the high robustness of the method and its potential application in the production of fluorescent films and inks.

Muhdesat, taşınmaz üzerinde sürekli kalmak maksadıyla meydana getirilen yapı ve/veya bitkilerdir. Bu nedenle muhdesat, kapsamına dahil olduğu taşınmazın bütünleyici parçasıdır. Muhdesat üzerindeki aynî haklar, taşınmazın bütünleyici parçası hâline gelmekle son bulurlar. Taraflar arasında ortaya çıkan uyuşmazlıklar, şayet muhdesatın meydana getirilmesi akdî bir ilişkiye dayanıyorsa bu hükümlere göre çözüme kavuşturulur. Buna karşılık, taraflar arasında akdî bir ilişkinin bulunmaması hâlinde, muhdesatın önceki sahibinin bütünleyici parça ilkesi nedeniyle mülkiyet hakkını kaybetmesi, ortaya çözümlenmesi gereken hukukî problemler çıkarır. Bu ihtimalde muhdesatı meydana getiren kişi, muhdesatın kendisi tarafından meydana getirildiğinin tespit edilmesini veya kendisine muhdesat bedelinin ödenmesini talep edebilir. Yargıtay, muhdesat bedelinin talep edilebilmesi için, muhdesatın tespiti davasından farklı olarak, derdest bazı davaların bulunmasını şart olarak aramamaktadır. Ancak Yargıtay’ın muhdesat bedelinin ödenmesini konu edinen çoğu kararında TMK m. 723 hükmü göz ardı edilerek, salt sebepsiz zenginleşme hükümleri dikkate alınmıştır. Ne var ki muhdesat, eşya hukuku bakımından haksız yapı/bitki niteliğindedir. Bu nedenle, TMK m. 723 ile sebepsiz zenginleşme kuralları arasındaki ilişkinin ayrıca incelenmesi gerekmektedir.
Postcolonial Indigenous Feminist Paradigm as a Strategy of Self-determination: A reflection on Papua Mimika Women in Matrilineal Tradition
Authors: Katmo Els Tieneke Rieke
Published: February 2023

Feminism for some people in Indonesia viewed as a Western concept. They claimed that, It is a concept which is not rooted in Indonesia’s values. Even though there are several studies conducted to examine women’s issues in Indonesia, the result of those studies is insufficient to develop a body of knowledge or feminist theory of Indonesia. Historically, Indonesia in the past was a colonized nation which Dutch (Euro-Western) for some decades. This indicated that knowledge production process in Indonesia has been hegemonised by so-called Western knowledge. Decolonization and indigenization on research methodology is crucial to be able to establish an Indonesia’s feminist theory. The historical context of Indonesia as a colonized nation as well as cultural context impacted on various women’s issues in Indonesia including West Papua’s women. Therefore, providing spaces for multiple paradigm such a Postcolonial Indiegnous in a research is needed. The process of decolonization and indigenization in a research will provide a knowledge that based on indigenous perspectives on Indigenous purposes in the production of knowledge.
Warsini! Are you not tired standing in the factory? A Reflection on Women’s Labour Pedagogy
Authors: Tiwon Sylvia
Published: February 2023

This article is a reflection on feminist education at the complex intersection of feminism, the workers movement and the movement towards social transformation in Indonesia. It raises questions about the effectiveness of gender training programs that have become almost a prerequisite for programs and funding among many non-government organizations, national and international. The writerargues that the institutionalization of gender training has been dissociated from the movement for transformational justice and from the concrete experience of workers.
Sexual Violence Discourse on Internet: Meme, Hoe and the Case of Eno Fariha
Authors: Agam Randie Ananda
Published: February 2023

Internet memes are presently gaining momentum as the hip media of the internet, yet it also brought the dated notion of sexism and violence against women. The notion is apparent especially after the recent case of violence and murder of Eno Fariha was transformedinto memes. Using several superficial aspect of media coverage on Eno’s case, such as the utilization of hoe for the murder, the creator of said memes basically implies that any women who violate practices identifiable with certain religion is subject to similar act of violence which befalls Eno. Moreover, taking into account that internet memes are made ‘just for laughs’, the humor of the meme becomes more prevalent than the violence discourse. Further inspection is needed on how much has the discourse spread, especially with memes’ quick and easy spread through the internet, and on its discursive relation with religion and domestification of women.
A Petri net model for vehicle scheduling problem
Authors: Dima Corina
Published: February 2023

Vehicle scheduling problem consists in assigning vehicles to a set of time-tabled trips, wishing to minimize the objective cost function. Two aprroaches of the problem were studied: single-depot vehicle scheduling problem (SDVSP) and multiple-depot vehicle scheduling problem (MDVSP). There are known several methos of solving this problem based mainly on liniar programming, branch and bound, graph colouring thechniques. SDVSP is solvable in polynomial time, while MDSVP is NP hard. The main propose of this paper is to present a model based on Petri nets for the vehicle sceduling problem. We defined priced timed workflow nets as a suitable model for SDVSP. We tried to emphasize the advantages of using Petri nets in order to describe this kind of planning problems.
Intimate partner violence and sexual and gender diversity in Spanish legislation
Authors: Laliga Mollá Mónica
Published: February 2023

The criminal justice system responds to gender-sex minority dating violence differently from violence in heterosexual couples, as far as national law in Spain is concerned, although it does receive specific mention in regional legislation. Research shows that violence in heterosexual couples shares characteristics in common with that which takes place in sexual minorities, from its prevalence to risk factors, some of them associated with the gender rules that surround affective-sexual relationships. There are also differences, however, and risk factors that are specific to violence in LGBTIQ+ couples. The aim of this paper is to analyze how such abuse is currently treated according to national and regional legislation prior characterization of this violence. Research shows the difficulties and limits of Spanish legislation to address this type of violence. In order to improve the way these problems are dealt with, the implications of the intersectional feminist perspective should be taken into account.
Classes of Population Mean Estimators using Transformed Variables in Double Sampling
Authors: THONGSAK Natthapat , LAWSON Nuanpan
Published: February 2023

Transformation techniques have been used to increase the efficiency of estimators in sample surveys. In this paper, some classes of population mean estimators using transformation on an auxiliary variable and on both the auxiliary and study variables have been proposed under double sampling. The proposed estimators’ biases and mean square errors are approximated up to the first order. A simulation study and application to a rubber production dataset have been used to illustrate the proposed estimators’ performance. The results show that they perform much better than other existing estimators under given conditions.
Intimate Partner Violence and the Influence of the Faith Factor
Authors: Muthangya Augustus , Muoki Stephen , Chidongo Tsawe-Munga , Wokabi Francis
Published: February 2023

The research article is based on a broader research project that set out to investigate the influence of Christian teachings and biblical texts on Intimate Partner Violence (IPV) among the Christian Women of Kilifi County of Kenya. Its specific focus is on how faith became a key coping strategy for women swimming in the troubled waters of IPV. Methodologically, it relied on oral interviews that were conducted among 30 women, 10 pastors, and 12 community leaders in Kilifi County. Overall, the research article argues that faith, in the larger realm of religion, is not only used to normalize IPV, but also utilized as a coping tool by victims. This further fuels a vice that is rooted in Judeo-African patriarchal ideals. Yet it has also established that some women adopted alternative strategies, outside the religious realm, so as to cope with the harsh reality surrounding them. The latter lost faith in religious approaches, and eventually adopted non-religious strategies in their endeavor to manage their circumstances. The need to revisit the idea of ‘separation’ and/or divorce, as a pragmatic approach for Christian women facing IPV, has been suggested as a workable strategy where need arises.

Authors: FU Qiankun , FU Jun , CHEN Zhi , REN Luquan
Published: February 2023

In the harvest of lodged corn in hilly areas, the low position of corn ears and the large slope of the land caused severe losses. The comprehensive performance of loss reduction and terrain adaptability was studied on three small corn harvesters. The tested harvesters were 4-row 4YZP-4Y wheeled harvester, 2-row 4YZLP-2C crawler harvester and 2-row 4YZLP-2C-AF crawler harvester equipped with spiral lifers. The results showed that the all-speed corn ear loss and grain loss of the 4YZP-4Y harvester were 55.6% and 57.6% lower than those of the 4YZLP-2C harvester, while those of the 4YZLP-2C-AF harvester was 23.2% and 17.3%, lower than in the case of the 4YZLP-2C harvester. The all-height corn ear loss and grain loss of the 4YZP-4Y harvester were 35.2% and 56.6% lower than those of the 4YZLP-2C harvester, those of the 4YZLP-2C-AF harvester were 19.9% and 24.9% lower than in the case of the 4YZLP-2C harvester. The smaller header width and larger roller compacted area of the 4YZLP-2C harvester were the main factors that caused harvest loss. Wider harvester header, auxiliary feeding devices and smaller roller compacted area were key methods to reduce the harvest loss of lodged corn in hilly areas. This study provides technical scheme and design references for harvesters on lodged corn in hilly areas.
