Published: April 2024

The light-induced N=N double bond isomerization of azoarenes lies at the heart of numerous applications ranging from catalysis, energy storage, or drug release to optogenetics and photopharmacology. While efficient switching between their E and Z states has predominantly relied on direct UV light excitation, a recent study by Klajn and co-workers introduced visible light sensitization of E azoarenes and subsequent isomerization as a tool coined disequilibration by sensitization under confinement (DESC) to obtain high yields of the out-of-equilibrium Z isomer. This host-guest approach is, however, still constrained to small, minimally substituted azoarenes with limited applicability and functionality in advanced multicomponent molecular systems. Herein, we expand the DESC concept to steer the supramolecular assembly of surfactants at the air-water interface. Leveraging our expertise with photoswitchable arylazopyrazole amphiphiles, we induce substantial alterations of the surface tension and surface excess of water through their reversible E-Z isomerization. After studying the binding of positively and negatively charged surfactants to the host, we find that the extent of surface activity differences upon visible light irradiation for both isomer states is comparable to those observed for direct UV light excitation. The method is demonstrated on a large range of concentrations (from µM to mM) and can be equally activated using green or red light, depending on the sensitizer chosen. The straightforward implementation of visible light photoswitch sensitization in a complex molecular network showcases how DESC enables the improvement of existing light-responsive systems and allows for the development of novel applications driven exclusively with visible light.

Published: April 2024

Hydrogen cyanide (HCN)-derived molecules and polymers feature in several hypotheses on the origin of life. Over half-a-century of investigations into HCN self-reactions have led to many suggestions regarding the structural nature of the products, and an even greater number of proposed polymerization pathways. A comprehensive overview of possible reactions and structures is missing. In this work, we use quantum chemical calculations to map the relative free energy of most HCN-derived molecules and polymers that have been discussed in the literature. Our computed free energies indicate that several previously considered polymerization pathways are not spontaneous and should be discarded from future consideration. Among the most thermodynamically favored products are polyaminoimidazole and adenine.

Molecular assemblies featuring two-dimensionality have attracted increasing attention, whereas such structures are difficult to construct simply relying on spontaneous molecular assembly. Here we present two-dimensional assemblies of acene chromophores achieved using a tripodal triptycene supramolecular scaffold, which have been shown to exhibit a strong ability to assemble molecular and polymer motifs two-dimensionally. We designed pentacene and anthracene derivatives sandwiched by two tripodal triptycene units. These compounds assemble into expected two-dimensional structures, with the pentacene chromophores having both sufficient overlap to cause singlet fission and space for conformational change to facilitate the dissociation of a triplet pair into two free triplets, which is not the case for the anthracene analogue. Detailed spectroscopic analysis revealed that the pentacene chromophore in the assembly undergoes singlet fission with a high quantum yield (ΦSF = 88±5%), giving rise to triplet pairs, from which free triplets are efficiently generated (ΦT = 130±8.8%). This demonstrates the utility of the triptycene-based scaffold to design functional π-electronic molecular assemblies.

Employing a qualitative methodology, the research involved semi-structured interviews with nine EFL teachers from two Vietnamese institutions representing a range of teaching experiences: novice, mid-career, and near-end-career. The technology acceptance model (TAM) and constructivist learning theory (CLT) framed the study, providing a dual perspective on technology integration in language education. The thematic analysis revealed a spectrum of challenges and opportunities in integrating ChatGPT into language teaching. Key challenges include concerns about over-reliance on AI, cultural and contextual misalignments, integration with existing teaching methods, language accuracy issues, impact on creativity, technical barriers, and ethical considerations. Conversely, opportunities identified encompass enhanced student engagement, personalized learning, professional development for teachers, improvement in language proficiency, reduction in teacher workload, encouragement of technological adoption, and fostering of critical thinking and creativity. The study suggests a need for balanced AI integration in language education, emphasizing personalized, interactive learning experiences and professional development for teachers.
A Social Ecological View in Overcoming the Environmental Crisis
Authors: Ainia Dela Khoirul , Arianto Bagus , Semesta Hanan Prawira , Zebua Sofia Natalia
Published: April 2024

Humans contribute to preserving nature and are even responsible for ecological disasters that occur. Humans have different characteristics from other living beings, which tend to be manipulative and want power. Conflicts related to exploiting natural resources will continue to arise if the harmony of social structures remains a problem. The orientation of modern humans tends to be materialistic and hedonistic, thus affecting the way they view their environmental systems, and contributing greatly to environmental damage. The increase in ecological disasters today cannot be separated from the poor environmental governance that tends to use natural resources without proper and sustainable environmental restoration. Through a socio-ecological approach, we seek to eliminate the commercialization of natural resources by adopting a social approach that embraces ecology, reconstruction, and communitarian approaches. This theory seeks to reconstruct and revise current views on social issues and environmental factors. The research data was collected through news fact collection and literature searches which were then subjected to descriptive and interpretive analysis. The results showed that (1) social ecology provides an understanding by prioritizing an egalitarian and democratic social structure so that humans can walk in harmony with nature, this aspect can be the basis for environmental management (2) social ecology is influenced by aspects of spirituality and egalitarianism in social structures to be a solution to the environmental crisis through changes in perspective on environmental management.
The Role of Socio-cultural Relations in Forming Community Perceptions of Geothermal Energy Existence in Lahendong, North Sulawesi, Indonesia
Authors: Yusrifa Fitria , Murtiningsih Siti , Utami Pri
Published: April 2024

Lahendong Village of the Tomohon Municipal is one of the geothermal energy-producing areas in North Sulawesi, Indonesia. Geothermal energy has been a part of Lahendong people's daily life for hundreds of years. The existence of geothermal manifestations and the natural wealth contained therein support the life of the Lahendong people. Through the cultural records of the Lahendong community, geothermal energy is not only defined as the energy that drives power plants but also part of the socio-cultural and historical relations of the Lahendong community since the beginning of the Lahendong Village. This study aims to explore, identify, and analyze how the role of socio-cultural relations forms the community's perception of geothermal energy development in Lahendong. This study used qualitative data collection techniques involving observation of local life, in-depth interviews with the local respondents, and a literature review. The interpretation of the data followed the Hermeneutics-Philosophical method. The results of this study show that the community has local knowledge about geothermal energy through Maengket culture, which combines regional dances and songs. The socio-cultural relations of the Lahendong people have a big role in shaping people's attitudes towards geothermal development. The Lahendong community adheres to the principle of giving in, living in harmony, and minimizing conflict. On the one hand, it is the basis for socio-cultural relations that are full of the value of unity. This cannot be separated from the existence of cultural values that are adhered to through the Mapalus system, namely Sitou Timou Tomou Tou and Torang Samua Basudara which are based on humanist values in life as individual and social beings. The Lahendong people believe that by respecting other people, and treating others like relations, conflicts will be minimized, including in efforts to develop geothermal energy.
Epistemicide in The Indonesian Food Estate Project in a Critical Approach of Boaventura de Sousa Santos
Authors: Krisnadi Leonardus Aditya , Wijanarko Andrean Ferry
Published: April 2024

Food is one of the basic human needs that must be met. Historically, food security has become a dominant topic in the public policies of various countries. Food security is defined as the availability of food and the ability of individuals to afford adequate foodstuffs. To achieve food security, it is necessary to develop a modern food production system, hence, the Indonesian government started a food estate program to achieve national food security. The food estate project is projected to convert potential land into agricultural land which will create food availability for the community. However, the food estate project has not been able to fulfil the promised yields. The food estate project ignores the participation of the local community which has long had a traditional food production system. The development of a food estate project that ignores the role of the community ultimately displaces local wisdom and replaces it with a modern food production system. The development of food estate projects that trigger deforestation and rely on monoculture farming also hurts land fertility; this approach is contrary to local wisdom which prioritises sustainability principles. This condition can result in epistemicide, the systematic murder of local knowledge which will have an impact on local community livelihood. This situation will result in the food estate project perpetuating a food production system dominated by Western knowledge and eliminating the local community’s sustainable food production system. Thus, epistemicide in a food estate project will create a situation where food availability and food affordability cannot be achieved. This research describes how epistemicide appears in Indonesian food estate projects. This research is philosophical research on actual problems that aims to present criticism of Boaventura de Sousa Santos’ epistemicide theory for Indonesian food estate projects.

Published: April 2024

Abstract. The relevance of the research topic lies in the fact that currently there is a steady tendency to increase the amount of electromagnetic radiation (EMR) occurring in the human environment, which negatively affects the healthy indoor environment and determines the focus of experimental research on protecting humans from factors hazardous to health. This article is devoted to the possibility of creating radioprotective building materials from man-made waste from various deposits of Armenia. Research is aimed at creating a comfortable living area inside buildings through the development of radioprotective sandwich-type materials that reduce the impact of EMR on human health. Work was carried out in the direction of developing samples of radio-absorbing structures and selecting radio-absorbing fillers. The laboratory obtained samples from stone processing waste and waste from the extraction of ore minerals with a density from -1500 to 2000 kg/m3, as well as samples based on expanded perlite and a mineral binder with a density of 250-300 kg/m3 as an internal heat-insulating layer and transferred to the National Scientific Laboratory named after A.I.Alikhanyan (Yerevan Institute of Physics) for proton irradiation. In this work, the samples were subjected to proton irradiation, since it is a component of cosmic radiation, as well as EMR and is capable of penetrating through layers of matter depending on its composition and properties. Some physical and mechanical properties of the resulting materials, such as compressive strength and water absorption, were also studied. In addition, the article contains a review of foreign experience in obtaining radioprotective materials with various types of radiation. At this stage, only proton irradiation has been studied, but work in this direction continues.

Subject of study: development of radioprotective materials of the “sandwich” type.

Materials and methods: waste of aluminosilicate rocks (tuffs) and waste from the extraction of ore minerals were used. The method of proton irradiation of the obtained materials was used.

Results: radioprotective materials have been developed that reduce EMR.

Conclusions: The possibility of obtaining radioprotective materials by introducing ore mineral mining waste into the composition of the composite material has been confirmed.

Published: April 2024

Abstract. The effect of semi-dry pressing on the strength of samples has been studied. It is shown that the optimal specific pressure for pressing samples from molding mixtures containing 10, 20, 30% slag-portland cement is 30Mpa. With the help of RCCP, static processing of experimental results was carried out and a regression equation was obtained for the dependence of the strength of the samples on the pressing pressure and the content of slag-portland cement in the molding mixture.

When examining the microstructure of the samples, it was found that the resulting material is a homogeneous and durable conglomerate, the crystals of neoplasms are evenly distributed over the mass and bind the sludge particles. A pilot test of the semi-dry pressing process of products has established the possibility of obtaining high-quality hollow bricks of the M100-M300 grades with a content of slag-portland cement in the mixture in the range of 10-30% (wt.).

The subject of the study: sludge products of flushing the screenings of the Sharkhinsky quarry in the production of wall building materials.

Materials and methods: sludge from the Sharkhinsky quarry and slag-portland cement from the Bakhchisarai cement Plant were used in the work. The structure of the samples was studied using electron scanning microscopy on a REM-106 SELMI microscope. Experimental and industrial tests were carried out on the equipment of the Aggregate company. The physical and mechanical properties of bricks and paving slabs were studied in accordance with the norms and standards established in GOST 6133-2019.

Results: The microstructure of the samples was investigated and it was found that the resulting material is a homogeneous and durable conglomerate, the crystals of neoplasms are evenly distributed over the mass and bind the sludge particles. Experimental and industrial testing of the semi-dry pressing process of products from molding mixtures based on the sludge of the Sharkhinsky quarry was carried out. It was confirmed that it is possible to produce high-quality hollow bricks marked M100-M300 using slag-portland cement in a mixture in the range of 10-30% (by weight), which fully meets the requirements set out in GOST 6133-2019

Conclusions: Sludge products from the flushing of the Sharkhinsky quarry screenings can be successfully used in the production of wall building materials, which contributes to waste disposal and improvement of the ecological state of the environment. Effective methods of disposal of sludge products make it possible to obtain high-quality building materials with high physical and mechanical properties and durability.
THE IMPACT OF THE FAILURE OF THE CLADDING PANELS ON THE THERMAL PROPERTIES OF HINGED VENTILATED FACADE STRUCTURES
Authors: Shurshilin E. , Olekhnovich Ya.
Published: April 2024

Abstract. One of the most common solutions for external enclosing wall structures are hinged ventilated façade structures, which, thanks to the use of air layers, provide increased energy efficiency. However, such systems have a number of drawbacks, including the formation of cold bridges in the places of attachment of facade panels, which can lead to significant problems in the operation of the system. In addition, it is known that individual facade panels can fall and refuse to work, which leads to a violation of the closure of the air layer and negatively affects the thermal properties of the structure. Therefore, it is necessary to take into account both the shortcomings of the facade structure itself and the problems associated with its operation in order to correctly assess the impact of the failure of the facade panels on the thermal properties of the structure as a whole. This problem is one of the most important for systems of hinged ventilated facades, as it can lead to a complete loss of thermal engineering properties of the structure. This study considers a theoretical solution to the problem of calculating the heat transfer resistance of air layers in hinged ventilated facade structures and organizing this solution into a consistent design methodology for further investigation of the effect of the fall of facing panels on thermal engineering properties of hinged ventilated facades. The main question of the study, consisting in assessing the impact of the failure of the cladding panels on the thermal properties of hinged ventilated facade structures, is considered in accordance with the provisions of the developed methodology and its subsequent mathematical analysis. The need for such a study is justified by the need to determinethe most effective ways to eliminate the shortcomings of hinged ventilated facade structures and increase their thermal properties.

Materials and methods: analysis of scientific and technical literature, mathematical analysis of the dependence of the resistance to heat transfer of air layers on the geometric parameters of the structure.

Subject of research: air layers in hinged ventilated façade structures.

Results: mathematical dependences are obtained that allow us to estimate the change in the moisture content of the thermal insulation material of hinged facade systems, the air velocity in the air layer and the air temperature in the air layer because of facing panel’s failure.

Conclusions: failure of facing panels of hinged facade systems leads to a change in the humidity of the thermal insulation and the parameters of the air layer, which can lead to exceeding regulatory requirements.

Published: April 2024

Latar belakang : Dismenorea primer (PDM) adalah nyeri haid yang terjadi tanpa adanya kelainan dari organ reproduksi secara nyata, yang timbul sejak menstruasi pertama dan terjadi biasanya dalam 6-12 bulan pertama setelah menarche. PDM berhubungan dengan kontraksi uterus yang dipicu oleh berkurangnya progesteron di awal menstruasi. Kontraksi ini menyebabkan iskemia uterus, yang akan memodulasi nyeri ditambah dengan meningkatnya kadar prostaglandin. Akupunktur adalah salah satu modalitas terapi yang sering digunakan untuk mengatasi nyeri, termasuk nyeri menstruasi. Akupunktur terbukti mengurangi nyeri secara efektif dengan efek samping minimal sehingga dapat meningkatkan kualitas hidup pasien.Kasus : seorang perempuan 26 tahun dengan dismenorea primer yang sudah terjadi sejak beberapa tahun terakhir dan semakin lama keluhan nyeri semakin memberat (NRS 6), hingga saat terjadi dismenorea menggangu pekerjaan dan kualitas hidup pasien. Dilakukan terapi akupunktur sebanyak 3 siklus menstruasi pada titik LI4 Hegu, SP10 Xuehai, serta titik Kidney daun telinga bilateral. Elektroakupunktur gelombang DD 4/20 Hz diberikan pada titik CV4 Guanyuan, CV6 Qihai, SP9 Yinlingquan, SP8 Diji, SP6 Sanyinjiao dan ST36 Zusanli, sebanyak 2 kali seminggu, selama 20 menit per sesi.Hasil : setelah 18 kali sesi akupunktur, skala nyeri pasien yang diukur dengan NRS berkurang dan kualitas hidup pasien yang diukur menggunakan kuesioner SF-36 hasilnya meningkat. Dalam follow up 3 bulan berikutnya setelah sesi akupunktur selesai, didapatkan bahwa saat menstruasi pasien hanya mengalami sedikit rasa tidak nyaman (NRS 1), tapi tidak mengalami nyeri seperti sebelum diterapi akupunktur. Sehingga akupunktur dapat berperan dalam penanganan dismenorea primer, baik sebagai preventif maupun kuratif.

Some Properties of Rings of the Type f(x),g(x)-clean
Authors: El Najjar Abdelwahab , S. Mohammed Akram
Published: April 2024

In [1], the authors introduced a property of rings called the f(x),g(x)-clean property. We investigate some new results about this property. In particular, we prove that the ring of matrices over a ring R is f(x),g(x)-clean if the ring R is f(x),g(x)-clean as well. We demonstrate, among many other things, that a ring's f(x),g(x)-cleanness may always be passed to R[[x]], but not always to its polynomial ring R[x].
Existence and Uniqueness Common Fixed Point in Fuzzy b-Matric Space
Authors: Nazar Ali Ban , Shani Hassan Alia
Published: April 2024

Multiple fixed points common to fuzzy spaces b-metric are  presented in this work. We provide an appropriate requirement for a sequence on the fuzzy space  b-metric  to be Cauchy, which is a significant outcome. As a result, we streamline the numerous theorem of point fixed proofs on a fuzzy space  for  b-metrics with established contraction conditions.
Impact of job satisfaction on teacher well-being and education quality
Authors: Assaf Joumana , Antoun Siham
Published: April 2024

The occupational well-being of teachers and their job satisfaction are interconnected, both influencing teacher performance and student well-being. After several years of ongoing economic and financial crises, this cross-sectional descriptive study highlighted several factors that impact the quality of education in relation to these concepts. To achieve this, a scale created through principal component analysis was distributed online. The responses of 297 school teachers, from both the public and private sectors were subjected to analysis using descriptive and logistic regression tests. The findings revealed a strong sense of self-efficacy among teachers, indicating their dedication to providing quality instruction to students on the one hand and helping them overcome challenges on the other. Additionally, the factor of income and financial security emerged as the primary concern for teachers, with approximately 80% of respondents expressing this sentiment. Similarly, collegiality, working conditions, and attitudes towards teaching itself were also sources of concern.
An overview of the study designs and statistical methods used in the determination of predictors of melioidosis mortality in Malaysia: 2010-2021
Authors: Mardhiah Kamaruddin , Nursyahiyatul-Anis Othman
Published: April 2024

Background: In Malaysia, the mortality from melioidosis infection was reported to be higher than in other infectious diseases. The research on melioidosis is still limited in Malaysia but slightly increasing.

Objectives: The objective of the study was to give an overview of the study designs, statistical methods, and comparison of research in identifying the predictors of melioidosis mortality in Malaysia between January 2010 to December 2021.

Data sources: Pubmed/Medline.

Study eligibility criteria: Original English-language articles were abstracted. The articles that identified the predictors of melioidosis from mortality in Malaysia only included. Letters to the editor, editorials, reviews, systematic reviews, meta-analysis, case reports, and any other ineligible articles were excluded.

Results: A total of eight studies were identified related to predictors of melioidosis mortality in Malaysia. From the selected articles, 87.5% were retrospectively collected. Five out of eight articles (62.5%) used the logistic regression in identifying the predictors of melioidosis mortality. Only one (12.5%) used advanced survival analysis methods of Cox regression analysis. Another 25.0% used Chi-square test.

Conclusions: Logistic regression methods remain the most common methods of analysis in publications on predictors of melioidosis mortality in Malaysia while retrospective research designs are preferred. There is a limitation of research in predictors of melioidosis mortality and the use of advanced statistical techniques reported using the melioidosis data in Malaysia. More published research on melioidosis will provide input to the clinicians on a more detailed understanding of how to improve the diagnosis of melioidosis and the prognosis factors of this disease.

Authors: IKENGA Veronica Uche  , OYITA Governor Ekene  , GBIGBI Theophilus Miebi
Published: April 2024

This paper examined the prospects and challenges of agricultural financing in Nigeria. It was observed that agricultural financing is all about providing services to the farmers who are traditionally not served by the conventional financial institutions. Agricultural financing holds a lot of prospects for Nigerians especially the poor as it will enable them develop their skills, engage in production and many others. Among the problems identified are access to banking services in rural communities, lack of acceptable collateral/ security, perceived high agricultural risk, lack of access to credit information, high cost of credit administration, access to market, infrastructural challenges and subsistence nature of farming. The various prospects highlighted include; economic empowerment of farmers, poverty reduction, gains from international trade, employment generations, rural development, skill development, new innovations, effective utilization of local resources and output expansion. Consequent upon the problems noted, the paper recommends that the supervisory authorities should enforce standards so as to address the issue of poor management of funds meant for credit disbursement.
