The EcoGothic and Contemporary Sri Lankan English Literature: Reading Ecophobia in Patricia Weerakoon’s Empire’s Children and Roma Tearne’s Mosquito
Authors: Daimari Esther
Published: August 2022

This paper explores contemporary Sri Lankan fiction as expressions and experiments in postcolonial EcoGothic writing by highlighting an intense relationship between ecology and place. By examining the novels of three contemporary Sri Lankan writers – Roma Tearne’s Mosquito, Michael Ondaatje’s Anil’s Ghost, and Patricia Weerakoon’s Empire’s Children, the article examines how certain landscape tropes such as the sea, the forest, ruins, caves, and tea plantations are shaped by the writers as gothic spaces to share their ecological concerns. The eerie plantations in Empire’s Children and the fecund forest, groves and the sea in Mosquito, and the caves and mass graves in Anil’s Ghosts allude to traumas related to postcoloniality, war, and military territorialization. Building upon theories of landscape, ecocriticism, and more specifically, the EcoGothic, the article draws upon works by Sharae Deckard and others to suggest how in these novels, the landscape is not just a setting for the stories but palimpsests of multiple histories of violence on both the people and the environment. The article examines how the novel enacts violence and spatial disorientation, closely connected with the gothic genre, suggesting Anglophone contemporary Sri Lankan fiction writers’ recurrent exploration of gothic and ecology in their works.
“A Perfect Place to Die”: Thinking the EcoGothic, Darkness, and the Dark Sweet in Gus Van Sant’s The Sea of Trees
Authors: Chang Kathryn Yalan
Published: August 2022

Located at the foot of Mountain Fuji in Yamanashi Prefecture, Japan’s gothic forest Aokigahara Jukai, is an (in)famous “suicide forest.” Drawing on Timothy Morton’s three threads pertaining to dark ecology and Elizabeth Parker’s notion of “ecoGothic,” both of which open up a more comprehensive perspective of the dark forest, this article argues that the analysis of Van Sant’s film The Sea of Trees (2015) on Aokigahara brings into question the stereotype of the horrible suicide forest for it not only invokes Morton’s sense of (dark-sweet) meditative space for people to ponder the meaning of life but also brings us to recognize the re-enchantment of the Gothic forest where the strangers have been encountered. This article is divided into four parts: (1) Thinking the EcoGothic; (2) Thinking Darkness; (3) Thinking Dark Sweet; and (4) Conclusion. In my reading, Van Sant’s film cautions us against the stigmatization of the Sea of Trees, exclusively challenging anthropocentrism, calls for a more nuanced aesthetic and spiritual perspective about Aokigahara.

Published: August 2022

Petani menghadapi risiko produksi yang terkait dengan perubahan hasil panen, fluktuasi harga dan ketidak-pastian finansial. Pemerintah membantu para petani mengatasi permasalahan tersebut melalui upaya perlindungan usahatani dalam bentuk asuransi pertanian. Penelitian ini bertujuan untuk menganalisis implementasi program asuransi usahatani padi (AUTP) di Kecamatan Tirto Kabupaten Pekalongan. Metode penelitian yang digunakan adalah studi kasus. Penelitian ini menggunakan pendekatan kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, studi kepustakaan dan dokumentasi. Informan dalam penelitian meliputi Jasindo, koordinator penyuluh, penyuluh dan petani. Data yang telah diperoleh dianalisis dengan menggunakan teknik reduksi, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa implementasi program AUTP di Kecamatan Tirto belum berhasil. Masih banyak petani yang belum mengetahui program ini, meskipun telah terdaftar sebagai peserta asuransi, keterlambatan dalam pengecekan lahan dan keterlambatan pembayaran klaim. Hanya pengurus kelompok tani yang mengetahui program ini. Petani lain mengetahui dari sumber informal. Hal ini terjadi karena sumber daya manusia dan fasilitas belum memadai. Pihak Jasindo dan penyuluh tidak melakukan sosialisasi secara rutin kepada petani, karena hanya dilakukan sekali sebagai akibat dari kekurangan sarana dan prasana. Hal ini menunjukkan bahwa kinerja implementor dalam pelaksanaan program AUTP belum maksimal. Rekomendasi dari penelitian ini ditujukan kepada pemerintah setempat untuk bekerja sama dengan pihak Jasindo dan penyuluh mengadakan sosialisasi secara menyeluruh ke semua petani.
IgE glycans promote IgG anti-IgE autoantibodies that facilitate IgE serum clearance via CD23
Authors: Plattner Kevin , Gharailoo Zahra , Zinkhan Simon , Engeroff Paul , Bachmann Martin , Vogel Monique
Published: August 2022

Background: IgE antibodies are involved in type-1
hypersensitivity. Cross-linking IgE bound to the high-affinity IgE
receptor, FceRI on effector cells with an allergen can cause
anaphylaxis. Recent studies have shown that IgE glycosylation
significantly impacts the ability of IgE to bind to its high-affinity
receptor FceRI and exert effector functions . We
have recently shown that immunization of mice with IgE in complex with
an allergen leads to a protective, glycan-dependent anti-IgE response
. However, to what extent the glycans on IgE
determine the induction of those antibodies and how they facilitate
serum clearance is unclear. We investigated the role of glycan-specific
IgG anti-IgE autoantibodies in regulating serum IgE levels and
preventing systemic anaphylaxis by passive immunization.
Methods: Mice were immunized using glycosylated or
deglycosylated IgE-allergen-immune complexes (ICs) to induce anti-IgE
IgG antibodies. The anti-IgE IgG antibodies were purified and used for
passive immunization. Results: Glycosylated IgE-ICs induced a
significantly higher anti-IgE IgG response and more IgG secreting plasma
cells than deglycosylated IgE-ICs. Passive immunization of IgE
sensitized mice with purified anti-IgE IgG increased the clearance of
IgE and prevented systemic anaphylaxis upon allergen challenge. Anti-IgE
IgG purified from the serum of mice immunized with deglycosylated
IgE-ICs, led to a significantly reduced elimination and protection,
confirming that the IgE glycans themselves are the primary drivers of
the protectivity induced by the IgE-immune complexes.
Conclusion: IgE glycosylation is essential for a robust
anti-IgE IgG response and might be an important regulator of serum IgE
level.
Is coronary artery transfer still the jugular for the arterial switch operation?
Authors: Sainathan Sandeep , Mulinari Leonardo
Published: August 2022

The outcomes of the arterial switch operation have improved over a
period of time with the elimination of coronary artery anatomy as a risk
factor for operative mortality in some series. However, cumulatively,
when all the series published so far are analyzed, two coronary
variations, namely the single sinus coronary artery origin and
intramural type, persist as risk factors for an adverse operative
outcome.
Study on Mechanism of Radial Long Cracks Propagation on Sliding Surface of Wheel Brake Discs
Authors: Xie Xiaodong , Li Zhiqiang , Yang Zhiyong , Li Weijing , Han Jianmin
Published: August 2022

Radial long cracks at bolt holes have been observed on steel brake discs
used in high-speed rail systems. The crack propagation process is
obviously different from traditional thermal fatigue propagation.
Because the causes of the cracks and corresponding propagation mode are
not well known, further study is warranted. In the present study, the
microstructure evolution near the sliding surface of a cast steel brake
disc was characterized. The variation in the mechanical properties of
the disc material under the influence of microstructure evolution and
temperature was analysed. Combining the establishment of the extended
finite element model (XFEM) with changes in mechanical properties, the
propagation mechanism of the radial long crack at the bolt hole on the
brake disc sliding surface was analysed. The microanalysis and tensile
test results showed that the grain size and the strength of material
gradient increased from the sliding surface to the core of the disc. The
simulation results showed that the interaction of strength decline and
high-level stress concentration in the vicinity of the bolt hole led to
rapid crack propagation along the radial direction of the disc. In
addition, the formation of the radial long cracks was equivalent to the
introduction of the fatigue crack source on the sliding surface, and the
crack was very likely to continue to propagate to the core of the disc
through fatigue propagation, which ultimately led to the failure of the
brake disc. Based on the results of this study, recommendations
regarding the presence of radial long cracks on the sliding surface and
maintenance procedures for the cast steel brake disc are proposed.

Postoperative Pain and Numbness in Endoscopic Ear Surgery: Patient Values and Outcomes
Authors: Chern Alexander , Sharma Rahul , Grewal Maeher , Golub Justin
Published: August 2022

Purpose: Transcanal endoscopic ear surgery (TEES) avoids a postauricular
incision, which has been shown to minimize pain and numbness. Our
objective is to assess how much patients value minimizing pain and
numbness relative to other postoperative otologic outcomes. Methods:
Cross-sectional anonymous surveys were distributed to otolaryngology
clinic patients in a tertiary care center. Patients were instructed to
rate how much they value various outcomes when undergoing hypothetical
ear surgery on a scale of 0 (not important) to 10 (very important).
Linear regression was used to analyze demographic predictors of valued
outcomes. Results: 102 patients responded (response rate 75%, 50%
male). 51% presented for otologic complaints; other represented
subspecialties included head & neck surgery, facial plastic surgery and
rhinology. 10% of survey respondents were Spanish-speaking. Outcomes of
highest importance included hearing (mean 9.3; SD 1.9), staff
friendliness (8.9; 1.8), numbness (8.3; 2.4), and pain (8.1; 2.5).
Outcomes of moderate importance included time spent under anesthesia
(7.0; 3.2), scar visibility (6.3; 3.5), incision size (5.5; 3.4),
incision hidden in the ear canal (5.4, 3.9), and surgery cost to the
hospital (5.1; 3.9). In linear regression analysis, increasing age was
associated with decreased value placed on size of incision (β=-0.06,
p<0.001) and visibility of scar (β=-0.07, p<0.001).
Conclusion: Patients placed very high value on minimizing pain and
numbness after ear surgery, nearly as much as a good hearing outcome.
This has implications for patient-driven interest in TEES, which has
been previously shown to reduce pain and numbness compared to the
postauricular approach.

Authors: Wołczański Tomasz
Published: August 2022

Safety logistics in the age of digitization of industrial plants is complex because it embodies the technologies of Industry 4.0 by integrating people and machines and individual processes. New technologies allow them to manage machines and equipment based on communication and mutual data flow. This creates a network of connections between products, value chains and business models. The activities associated with the implementation of the Industry 4.0 concept include human interaction and occupational safety logistics in addition to technology. Digitalization creates new options for the organization of work areas and thus new opportunities for work safety logistics. Modern digitalization has an extremely positive impact on occupational safety and productivity. Intelligent work safety management requires the use of new Industry 4.0 technologies and solutions developed for the work environment area. The purpose of this paper is to present a systematic literature review covering the area of intelligent Industry 4.0 technologies in occupational safety logistics, including an indication of the importance of safety in the work environment, in the context of the continuous digital transformation of enterprises
Leseleksens plass i norskfagets begynneropplæring
Authors: Hoem Toril Frafjord , Wagner Åse Kari Hansen
Published: August 2022

Lekser har lange tradisjoner i skolen, til tross for blandede funn når det gjelder verdien av disse. En positiv verdi av lekser vil være avhengig av hvordan lekser rammes inn og følges opp i den daglige undervisningen. Basert på filmede observasjoner fra seks andreklasser undersøker denne artikkelen hva som kjennetegner det lekserelaterte lese- og tekstarbeidet i norskfaget. Vi stiller følgende forskningsspørsmål: (1) Hvilken plass har leselekser i norskundervisningen?, og (2) Hva slags tekstarbeid finner sted i tilknytning til leselekser? Vi finner betydelig variasjon i hvor stor del av opplæringen som er knyttet til lekserelatert arbeid og hvordan dette arbeidet rammes inn og følges opp. Mest effektivt og meningsfylt framstår leksearbeidet når det er en integrert del av undervisningen. Elevene får, ikke uventet, mest øvelekser fra læreboka for å utvikle kodekompetanse og leseflyt, men formålet med leksene er ofte underkommunisert ut over at teksten skal leses tre ganger. Det fokuseres i liten grad på at elevene skal lære strategier for avkoding og forstå hva leseflyt innebærer. Hva tekster som helhet handler om, får lite oppmerksomhet, og elevene inviteres ikke til å reflektere kritisk over teksters form og innhold. Mye tid går dessuten med til organisering av leksearbeidet, med tilhørende lavt læringstrykk.
English abstract
Reading homework in early literacy education (L1) in Norway
Homework has a long tradition in schooling, despite mixed findings regarding its value and effect. Any positive value of homework will depend on how the homework is framed and followed up in the daily teaching. Based on filmed observations from six second-grade classrooms, this article examines what characterises homework-related reading and text work in L1 in Norway. We ask the following research questions: (1) What place does reading homework have in L1 instruction? and (2) What kind of text work takes place in connection with the reading homework? We find considerable variation in the amount of teaching time that is connected to homework-related work and how this work is framed and followed up. Homework appears to be most effective and meaningful when it forms an integral part of the teaching. Most of the texts used for reading homework are taken from school textbooks and focus on developing code skills and reading fluency, but this purpose is often not communicated beyond the expectation that the text will be read three times. Teaching does not include strategies for decoding or understanding what reading fluency entails. The synthesising oftexts receives little attention, and students are not invited to reflect critically on the form or content. A lot of time is spent on organising the homework, with associated low learning outcomes.
Synthesis and characterisation of novel phosphonate-based linkers and metal-organic frameworks based on tetravalent metals
Authors:   , Shearan Stephen J. I.
Published: August 2022

The interest in metal-organic frameworks (MOFs) has skyrocketed in the past two decades, owing mainly to their tunable structures and properties. The main approach for this thesis is to explore the synthesis of novel metal(IV) phosphonate frameworks, mainly based on zirconium(IV). Exploring the effect of linker geometry on the structure of MOFs, a series of non-linear linkers were synthesised and assessed on their effectiveness in forcing the structure away from the conventional pillared-layered structures observed in a large portion of metal phosphonate literature. The subsequent structures were then assessed for their suitability in applications such as carbon capture and photocatalysis. With the interest in crystallisation evident, an in-depth in situ XRD crystallisation study was also carried out on two existing Ce(IV)-based MOFs, one of which had been identified for its promising carbon capture properties, and was also subject to a scale-up study to assess the potential for commercial deployment.

Authors: Matyusheva N. V. , Khudyakova V. M.
Published: August 2022

Introduction. Vegetable production is one of the branches of plant cultivation that is distinguished by the specifics of conducting technological processes, characterized by the structural variety of cultivation facilities and special working conditions. Injuries of employees are the serious problem in the workplace now. The body of a worker is exposed to a complex of unfavorable production factors: mineral fertilizers, pesticides and products of their metabolism: heating microclimate, high humidity, significant physical exertion. If agrotechnical techniques are followed, they cannot be a source of deterioration of health. Violation of sanitary and hygienic regulations and technological schemes for growing crops increases the risk of health problems and affects the ability to work.

Problem Statement. The task for the study is to develop a simplified design to lower vegetables into storage, improve working conditions and safety of workers. Theoretical Part. Occupational safety improvement in agriculture is necessary, first of all, from the point of the preservation and purpose of the system as a mechanism for protecting the interests of workers, guaranteeing the preservation of their life, health, working capacity in the process of professional activity, as well as for the purpose of agricultural production efficiency. There is an urgent problem of safety when laying vegetables in containers. The main type of injury to workers is occurred during work for eliminating technical and technological failures. Conclusions. As a result of the research, market analysis and evaluation of the competitiveness of the development under consideration, the main distinguishing features of the proposed device from the existing ones are determined. This design can be recommended for further integration into the existing enterprise system, as well as for use in any agricultural enterprises.
On the Control of Metal Strength of Structural Elements of Floating Cranes
Authors: Vernezi N. L. , Rusakov V. A.
Published: August 2022

Introduction. The article is devoted to the issues of non-destructive testing of mechanical characteristics of metal structural elements of cranes. The reliability of cranes largely determines their safety. The main manifestations of operational failures of floating cranes are analyzed on the example of the UMK-2 crane. It is noted that 27% of failures occur due to the loss of metal strength of their structural elements. Determination of the causes of such failures is possible by conducting non-destructive testing of the mechanical characteristics of the failing structural elements metal. The paper provides the principle of one of the methods of non-destructive strength control based on the impact insertion of a conical indenter into the metal under study with the subsequent analysis of the intermediate parameters of this insertion. The results of measurements of the mechanical characteristics of the metal deformed during the operation of the boom strut of a floating crane are given. The current measured values of the mechanical characteristics of the metal obtained at various points of the strut are processed for compliance with the three-parameter Weibull law to obtain the minimum values of these characteristics. As a result of such processing, it is stated that the minimum values of yield strength, strength and elongation are lower than those claimed by the design documentation for the crane. This may be one of the reasons for the deformation of the structural element during operation.

Problem Statement. The application of the method of non-destructive testing of the metal of the boom strut is considered in order to assess the mechanical characteristics and establish possible causes of its deformation when analyzing the operational reliability of the crane.

Theoretical Part. When identifying possible causes of deformation or destruction of steel elements of crane structures, it is proposed to apply a method of non-destructive testing of mechanical characteristics based on the impact insertion of a conical indenter into the test surface. Further, it is proposed to process the obtained sample of values of the measured characteristic for compliance with the three-parameter Weibull law to estimate the shift parameter or the minimum value of this characteristic.

Conclusions. The minimum values of the tensile strength, yield strength and relative elongation of the metal of the deformed boom strut of the UMK-2 crane were obtained on the basis of the application of the method of non-destructive testing with subsequent approximation of statistical information by the Weibull distribution law. A conclusion was made about the reduced strength characteristics of the metal relative to those stated in the technical documentation, which could cause deformation of the crane boom element.
Ballistic Resistance of Steel with the Structure of a Natural Ferrite-Martensitic Composite
Authors: Pustovoit V. N. , Dolgachev Yu. V. , Dombrovskii Yu. M.
Published: August 2022

Introduction. For steel armor materials, it is important to reduce the thickness and, consequently, the metal consumption of the protective structure. The previously developed class of materials with the structure of a natural ferrite-martensite composite (NFMC) has characteristics that favor the inhibition of crack development under impact loads and has prospects as an armor material.

Problem Statement. The purpose of this work is to evaluate the possibility of using NFMC materials for armor protection devices based on the results of ballistic resistance tests under a high-power concentrated impact (a projectile flying at a hyper-high speed).

Theoretical Part. The study of ballistic resistance was carried out on samples of steel 14G2 processed according to various modes. The samples had the shape of plates and a square grid on the surface. Simulation tests of the impact of heat-strengthened dowels from a powder-actuated tool and firing of military small arms at the testing site from an SVD sniper rifle and an AK-74 assault rifle with machine loading ammunition were carried out. The results of simulation tests showed a clear advantage of steel with the NFMC structure. The comparison of the results of firing with military small arms has showed that the ballistic resistance of steel with the NFMC structure depends on the ratio of the volume fractions of ferrite and martensite, which cause different thicknesses of the ductile and strong components of the composite. The highest resistance was observed for a sample with an NFMC structure processed according to the regime: quenching 730°C and tempering 180°C.

Conclusions. Steels treated for the NFMC structure can provide effective protection for military personnel with a lower material consumption of armor protection devices, which is due to a special method of braking destruction during a high-power local impact. Thus, the practical application of the developed class of natural composite materials seems promising for obtaining an armor plate with a thinner thickness, which helps to reduce the weight of combat vehicles, increase their mobility and reduce fuel consumption.
Manufacturing Technology of Sliding Bearings from Ferro-Graphite Compositions
Authors: Egorov M. S. , Pustovoit V. N. , Tsordanidi G. G. , Egorova R. V.
Published: August 2022

Introduction. The development of modern technology imposes increasingly stringent requirements on materials operating under conditions of high pressures, speeds, deformations and aggressive media. The use of powder metallurgy methods in the creation of new materials makes it possible to provide a rational combination of production technology, structural and performance characteristics. Powder steels used in mechanical engineering are of great interest among the materials obtained by powder metallurgy. The article explores the possibility of manufacturing porous bearings made of iron powder for fan motors of domestic air conditioners instead of porous bearings made of bronze graphite.

Problem Statement. To ensure long-term operation of fan motors from metal powders, it is necessary to create porous bearings without alloying additives with the required mechanical properties. This requires a series of experimental work to determine the dependences of mechanical and technological properties on the sintering temperature, compacting pressure and the porosity of samples.

Theoretical Part. As a theoretical description, the use of a mold with an additional draining gap, which provides high bearing density at low compacting pressure, is analyzed. The effect of compacting pressure on the strength of sliding bearings under mechanical deformations depending on the sintering temperature is also considered.

Conclusions. It was established in the work that during the sintering of sliding bearings at a temperature of 800-1100°C, a significant charge carburization occurs due to the decomposition of zinc stearate in closed pores. As a result, a ferritepearlite structure is formed, due to which the bearings are well calibrated and have high wear resistance when paired with a steel shaft. Optimum sintering modes and compacting pressures were selected, which showed high reliability and durability of the products obtained from pure iron powder.
Technological Methods of Boriding Products from Stainless Alloys Operating in Aggressive Conditions
Authors: Egorov M. S. , Dombrovskiy Yu. M. , Tsordanidi G. G. , Egorova R. V.
Published: August 2022

Introduction. The durability and other performance characteristics of machine parts are largely determined by physical and chemical state of thin surface layers. The localization of hardening processes in these layers serves as a significant reserve for increasing the service life of parts while reducing the cost of manufacturing materials. One of the most progressive directions of strengthening technology is the application of protective coatings on the working surfaces of machine parts.

The article investigates the process of sintering compacts from steel PKh23N18 in boron carbide powder in containers with a fusible seal. It has been established that sintering in such containers provides high mechanical characteristics of sintered steel with good reproducibility of the sintering process.

Problem Statement. To improve corrosion resistance, as well as to improve wear resistance of friction surfaces of products and machine parts operating in aggressive environments, it is necessary to choose a rational technology of chemical-thermal treatment that allows increasing the mechanical and technological properties of products.

Theoretical Part. As a theoretical description, the use of various methods of stainless steel boriding is analyzed, and the dependences of changes in the mechanical and technological properties of samples on various boriding schemes and methods for obtaining samples are considered.

Conclusions. It was established in the work that the increase in strength of samples subjected to boriding sintering in an autonomous gaseous medium occurred due to the absence of oxidation and deep saturation with boron (volumetric strengthening) through the vapor-gas phase. The use of container technology makes it possible not only to simplify the technology, but also to ensure the preservation of material properties, regardless of the presence of a protective gaseous medium in the thermal shop.
Thermal Spraying of Coatings on Aluminum Alloys of Combine Parts
Authors: Egorov M. S. , Fominov E. V.
Published: August 2022

Introduction. At the present stage of technology development, special importance is given to improving the efficiency and durability of machine parts and especially parts of assemblies operating under increased loads. The problem of increasing reliability in the conditions of intensification of production, energy and resource conservation poses the task of introducing new technological processes and the use of modern materials into production. Often, the weakest element in the «material – working» environment system, which determines the operating conditions and the resource of mechanisms, is the surface of the material. Therefore, an important role in increasing its wear resistance is played by coatings that protect parts from the destructive influence of working environments.

Problem Statement. The main objective of the research is the development of technological modes for applying thermal coatings to the belt pulleys of the TORUM 750 combine harvester by Rostselmash, as well as the selection of optimal coatings to increase the durability and wear resistance of the pulley surface.

Theoretical Part. As a theoretical description, the application of various coating options is analyzed, as well as the mathematical processing of experimental data on the adhesion strength between the aluminum surface and the coating material is considered.

Conclusions. The studies carried out by the authors have shown that it is advisable to conduct thermal spraying on aluminum alloys of belt coatings on a heated substrate (preheating temperature from 210°C). In the case of spraying coatings on the rubbing surfaces of pulleys, the surfaces should be regularly cooled.
Optimization of Process Parameters for A Wind Turbine in A Ducting System Through The Taguchi-Pareto-DEMATEL Method
Authors: Oke Sunday Ayoola , Abayomi Oluwatayo Johnson
Published: August 2022

In a heating, ventilation, and air conditioning (HVAC) unit, ducting systems with wind turbines are responses to the system’s high wind energy yields. However, the efficiency of the system is a challenge. To tackle this issue, optimization of process parameters plays a central role. Unfortunately, while applying the Taguchi method as an optimization procedure for high wind energy yields, the existing procedures are not clear enough to project a deep understanding of how to establish priorities among the system's parameters and yet showcase relationships among them. Consequently, this study proposes a new approach, the Taguchi-Pareto DEMATEL (Decision making trial and evaluation laboratory), to establish priorities among the process parameters and concurrently define associations among the parameters of the wind turbine inducting system. The proposed method amalgamates the Taguchi-Pareto method, which prioritizes the process parameters and minimizes the anticipated value of the variance with DEMATEL. The DEMATEL method is infused into the structure to verify interconnection among the wind turbine process parameters and establish a map to show the comparative association within the parameters. Thus, the DEMATEL framework probes and solves the complex energy yield problem of the wind turbine. The parameters used are input air pressure, ducting height, the distance between the blower and the pipe, total effective length, and the gap between the truck and runout. The desired optimal value of parameters for the proposed method are as follows: P2H2TG2EL1BD1, which is interpreted as 2.5m/s of air pressure, 0.5in of height, 1in of truck gap, 0.5in of effective length, and 0.5in of blower distance. The optimized parameters of a ducted wind turbine in an HVAC system could be of vast interest to HVAC systems to plan and monitor wind turbine performance.

A Morphogenesis Account of Student Leaders’ Development of their Agency in their Undergraduate Residences at Stellenbosch University
Authors: Davids Delecia , Fataar Aslam
Published: August 2022

This article offers an account of the development of student leaders’ agency within the institutional culture of their residences at Stellenbosch University (SU). Residences at formerly white universities such as SU are struggling to align their welcoming practices and cultures to the requirements for immersion of the diverse students who now live in them. This article focuses on student experiences of alienation in SU residences with a particular interest in how they develop adaptative responses to establish a place for themselves in them. It is based on focus group discussions with student leaders which provided insights into their perceptions of their residence cultures and how they established their agency in this environment. The analysis presented in the article is based on Archer’s theoretical approach to morphogenesis. The first data section of the article discusses the interaction between the students’ immersion in the institutional culture of their residences, on the one hand, and the acquisition of their initial identifications in response to the environmental cues of their residences, on the other. The second data section discusses the students’ active acquisition of their social identities, which allowed them to establish their aspirant pathways at the residence and the university. Overall, the article offers an account of morphogenesis at work at the institutional level of SU’s residences with a specific focus on the adaptive behaviour of student leadership in this university context.
Psychological Stamina and Thinking Style Preferences among First-Year University Students
Authors: Mason Henry , Craven Ane , Fredericks Megan
Published: August 2022

This study investigated the association between psychological stamina (grit, mindset and hardiness) and thinking style preferences among South African university students. Data were collected from 369 first-year university students using measures of grit, mindset, hardiness and thinking style preferences. The results indicated that different thinking style preferences were related to grit, mindset and hardiness. We argue that thinking styles should be considered as an important variable when supporting first-year students. Additionally, the role of grit and hardiness in student success should be considered in conjunction with the thinking style preferences of students. Avenues for further research are considered.
Design-Based Research (DBR) as an Effective Tool to Create Context-Sensitive and Data-Informed Student Success Initiatives
Authors: van Zyl Andre , Karsten Ilse
Published: August 2022

Sub-Saharan Africa has the lowest higher education (HE) participation rate of any region in the world at under 10%. Large numbers of students are entering the various systems, often from non-traditional backgrounds, which contributes to making an already difficult transition even more difficult. In many instances, well-intended interventions and initiatives are imported from elsewhere or based on “common sense”, but they are often not very effective. This raises a crucial question: How can institutions best devise context-sensitive and effective student assistance programmes? Design-based research (DBR) uses an iterative and longitudinal process that involves theory, participant inputs, peer inputs and stakeholder inputs to cyclically develop theoretically informed, contextually sensitive and appropriate interventions. Most practitioners could benefit from a better understanding of this process when designing interventions. This article elucidates DBR as a phased intervention-development process aimed at assisting students to integrate into HE and focuses primarily on the methodological approach on which it elaborates using examples from a PhD study.

ABSTRACTIntroduction: Rice husk silica has been studied as a filler in dental composite, however, the mechanical properties of the resulting composites are below the commercial due to the poor surface modification between silica and resin matrix. 3-methacryloxyprpyltrimethoxysilane (MPTS) is one of the coupling agents that are effective to modify the silica surface. The purpose of this study to analyze the effect of MPTS on the diametral tensile strength (DTS) of the self-made composite using rice husk silica.  Methods: The research type of this study was an experimental research laboratory. The samples (26 samples) were divided into two groups, namely the test group (using MPTS-modified silica) and the control group (using non-modified silica). The samples were cylindrical in shape with a diameter of 6.0 ± 0.1 mm and a height of 3.0 ± 0.1 mm according to ANSI/ADAS No. 27, 1993 and ISO 4049, 1988. The Fourier Transform Infrared (FTIR), HORIBA, was used to characterize the MPTS grafting on the silica surface. The DTS value is measured by Universal Testing Machine (UTM), Lloyd LRX Plus. Results: FTIR presents the additional peak of carboxyl and methacryloyl group at 1716, 1555, and 1410 cm-1 wavenumber, respectively in MPTS-modified silica. The DTS value of the test group was 43.40 ± 4.43 MPa and the control group was 25.80 ± 2.63 MPa. The test group was significantly higher than the control group (p-value = 0.001). Conclusion: The MPTS is effective to enhance the DTS value of rice husk silica-based composite.Keywords: Rice husk silica; dental composite; diametral tensile strength; 3-methacryloxypropyltrimethoxysilane.
The Effect of Dividend Policy on Stock Market Price Volatility of Banks in the Gulf Cooperation Council (GCC) Markets:
Authors: Ally Zawadi
Published: August 2022

This study examined the effect of dividend policy on the stock market price volatility of banks in the GCC markets. The study data were obtained from the annual financial reports and accounts of the selected sampled banks. The study used the panel data analysis fixed effect regression model.  The findings revealed that dividend yield and dividends payout does not influence the market share price in the GCC market. Therefore, they do not affect the GCC banks’ market share price, thus the findings of the study support the dividend policy irrelevance theory.  The study recommends that managers in the GCC banks should focus on and emphasize allocating more funds in investment rather than paying dividends. The findings have important practical implications for the policymakers on dividends in the GCC banks due to unstable and inconsistent trends of dividend payments and making it difficult for shareholders on dividend policy decisions predictions
En-gendering human-wildlife interactions in Northeast India: towards decolonized conservation
Authors: Banerjee Sayan , Sharma Shalini
Published: August 2022

This article applies a feminist political ecology framework to analyze a particular case of human-wildlife interaction from northeastern India, linking it to the emerging paradigm of 'decolonized conservation.' Through the oral testimonies of local community members with regard to living close to wild Asian elephants in a forest-agriculture landscape matrix of rural Assam, this article argues that place-based conceptualizations of 'wildlife', 'forest dependency' and 'living with wildlife' are affected by gendered roles and responsibilities, gendered access to spaces and gendered interaction with wildlife. By doing so, this article argues for (i) extending the discourse on 'decolonized conservation' towards the role of gender in rethinking these place-based conceptualizations and (ii) bringing forward such 'en-gendering' into redesigning wildlife policies, as that will have the potential of ensuring feminist environmental justice as well as positive conservation outcomes.
