Published: December 2023

Chennai is a rapidly urbanizing Indian mega-city and experiences flooding frequently. Literature state that climate change and land use change have a significant impact on the runoff generated every year, making it essential to study the historical trend and forecast changes in land use land cover (LULC) and climate to model runoff. This study considered Adyar watershed for LULC change detection, climate change analysis, and flood forecasting for 2030 and 2050 based on LULC and runoff from 2005 and 2015. A coupled hydrologic–hydraulic model (HEC-HMS and HEC-RAS) was developed to assess flooding for future LULC and climate scenarios. LULC analysis shows an increase in built-up cover by 6%. Climate analysis shows 74% probability of increase in precipitation intensity between 2015 and 2050 compared to 2015. It was observed that depth of flooding increased by 19.4% in 2030 and 60.4% in 2050 compared to 2015. This study makes a structural proposition for flood mitigation through flood carrier canals on the downstream reach of the river which flows through Chennai. The canals were found to significantly reduce overbanking, providing protection against flooding. This is the best measure for providing the highest flood reduction for the study area.

Authors: Volobuev V. V.
Published: December 2023

Relevance. The article discusses the peculiarities of the diet of the population of the city of Kursk in the early years of Soviet power. This issue has not been sufficiently disclosed in the scientific literature. The conclusions made on the basis of the study determined the relevance of the work.

The purpose of the article is to form an idea about the nutrition of the population of the city of Kursk in the early years of Soviet power.

The objectives arising from the set goal are to: 1) indicate the nutritional norms of the population in the first post-revolutionary and post-war years; 2) identify the differences in the nutrition of different segments of the population of the city of Kursk; 3) determine the degree of sufficiency of nutrition of citizens in the early years of Soviet power.

Methodology. The methods of objectivity, scientific, historicism were applied in the work, in addition to which historical-comparative and chronological approaches were used.

Results. Revolutionary events and the civil war led to a rapid deterioration of the food situation in the city of Kursk. Bread became the main product on the tables of the Kurians. The food set was dependent on the category of the population. Highly skilled workers had a higher income, and, consequently, a better set of food products. Employees were inferior to them. Non-working citizens had a completely meager diet. The Soviet government raised the issue of improving food conditions, was engaged in the organization of public catering in the city.

Conclusions. The food of the Kurians was determined by the state of the country's economy. Nutritional standards of the population in the first post-revolutionary and post-war years were reduced. The shortage of food in the early years of Soviet power was palpable. There were differences in the nutrition of different social strata of the population of the city of Kursk, the most complete was the table of highly skilled workers.
Review of the Monograph of Doctor of Law, Professor Sergey Fedorovich Milyukov, Doctor of Law Andrey Vyacheslavovich Nikulenko "Causing harm during the Detention of a Person who Committed a Socially Dangerous act ". 2nd ed., reprint. and additional. St. Petersburg: Legal Center, 2020. 768 p.

Relevance. In the review, the authors evaluate the monographic work of Doctor of Law, Professor S. F. Milyukov, Doctor of Law A.V. Nikulenko: "Causing harm during the detention of a person who committed a socially dangerous act." In the realities of today, the scientific, theoretical and practical problems of the implementation of the institution of causing harm during the detention of a person who committed a crime, as an independent circumstance excluding the criminality of the act, have not lost their significance.

The purpose of the study: to conduct a comprehensive comprehensive scientific analysis of the monographic

work.

Objectives: to assess the relevance and novelty of the content, the depth of the problem formulation and solu-

tion of the designated tasks, the scientific and practical significance of the results of the monographic research.

Methodology. The review was based on general scientific (analysis, synthesis, comparison, etc.), private scientific and special legal methods of cognition. and correctly

Results. The team of authors made a proposal for a number of amendments to the current norms of Chapter 8 of the Criminal Code of the Russian Federation and supplementing it with Article 381 "Detention of an imaginary assailant", Article 421 "Error in the presence of circumstances precluding the criminality of the act"; amendments to articles of the Special Part of the Criminal Code of the Russian Federation concerning the excess of measures necessary for detention; on the settlement of compensation for material and other (for with the exception of moral) harm in a civil procedure through the improvement of civil legislation.

Conclusion. Modern domestic legislation focuses on the regulation of the conditions for the legality of causing harm during the detention of a person who has committed a socially dangerous act, which should apply to specially authorized officials without any exceptions and substitute criminal legal regulation and have priority over departmental regulations. The proposals made, together with the adoption in the future by the Supreme Court of the Russian Federation of a resolution on all institutions excluding criminality of the act, will be able to ensure a uniform approach in law enforcement practice and contribute to strengthening the rule of law.

Authors: Bazarov A. A.
Published: December 2023

Relevance. In the conditions of active informatization and digitalization, the number of operating information systems used by the user to meet various cultural and (or) economic needs increases, the value of accounts, a technological solution that allows accumulating information and data in a certain information system increases. The author considers the problems of the possibility of inheritance of accounts in information systems, methods of their solutions. The concept of considering an account as a digital asset is proposed – a new object of civil turnover, an object of inheritance.

The purpose of the work is to develop the concept of inheritance of accounts (accounts) in social networks in the Russian Federation, to determine their legal nature.

Objectives: to analyze the current legislation and judicial practice of the Russian Federation in the field of legal regulation of accounts (accounts), their inheritance, to investigate the doctrine of private law and to form the concept of inheritance of accounts (accounts) in social networks in the Russian Federation.

Methodology. In the process of working on the research, general scientific research methods and methods inherent in modern private law science were used. We are talking about the use of methods of analysis and synthesis of information, data interpretation. The analysis of the current legislation in the field of commercial turnover of information is made.

Results. The absence of a regulatory framework revealing the legal nature of accounts (accounts), their place in the system of objects of civil turnover is determined. The economic significance of the account (account) has been determined for a specific user of the social network and (or) his heirs. The legal problem of inheritance of accounts (accounts) is indicated.

Conclusion. The conducted research provides the basis for an unambiguous conclusion about the absence of the necessary legal mechanisms for the inheritance of accounts (accounts), the absence of a normative definition of the legal essence of this phenomenon. The necessity of implementing the legal modernization of civil legislation in the context of the actualization of the problem of account inheritance is substantiated.
The cost of doing nothing: Testing the benefits of water disposal risk reduction with water management Activism investing in Latin America
Authors: De la Torre-Torres Oscar V.
Published: December 2023

Objective: This paper answers What would the performance of an investor be if she or he invested only in public companies with proper water management practices in Latin America (LATAM)? Methodology: The research uses the water-to-revenues (WTR) ratio to measure water management quality. It simulates the performance of an investor invested mainly in companies with the best WTR (from January 6th, 2005, to Abril 20, 2022). Results: Comparing the simulated portfolio’s performance against a broad market portfolio, the results suggest that both portfolios have similar performance in the short term. In the long term, the tests found that the WTR has a low systematic (market) risk (beta of 0.26), and its performance is more stable (mean-variance efficient) than the market portfolio. The tests also control the impact of some LATAM currencies’ depreciation. Conclusions: The results could be useful for investors to engage in water management activism through investing, motivate companies to engage in better water management practices, and reduce the future risk that water disposal represents to the world in years to come.
Risk Prediction of Emergency Department Visits in Patients With Lung Cancer Using Machine Learning: Retrospective Observational Study
Authors: Lee Ah Ra , Park Hojoon , Yoo Aram , Kim Seok , Sunwoo Leonard , Yoo Sooyoung
Published: December 2023

Background

Patients with lung cancer are among the most frequent visitors to emergency departments due to cancer-related problems, and the prognosis for those who seek emergency care is dismal. Given that patients with lung cancer frequently visit health care facilities for treatment or follow-up, the ability to predict emergency department visits based on clinical information gleaned from their routine visits would enhance hospital resource utilization and patient outcomes.

Objective

This study proposed a machine learning–based prediction model to identify risk factors for emergency department visits by patients with lung cancer.

Methods

This was a retrospective observational study of patients with lung cancer diagnosed at Seoul National University Bundang Hospital, a tertiary general hospital in South Korea, between January 2010 and December 2017. The primary outcome was an emergency department visit within 30 days of an outpatient visit. This study developed a machine learning–based prediction model using a common data model. In addition, the importance of features that influenced the decision-making of the model output was analyzed to identify significant clinical factors.

Results

The model with the best performance demonstrated an area under the receiver operating characteristic curve of 0.73 in its ability to predict the attendance of patients with lung cancer in emergency departments. The frequency of recent visits to the emergency department and several laboratory test results that are typically collected during cancer treatment follow-up visits were revealed as influencing factors for the model output.

Conclusions

This study developed a machine learning–based risk prediction model using a common data model and identified influencing factors for emergency department visits by patients with lung cancer. The predictive model contributes to the efficiency of resource utilization and health care service quality by facilitating the identification and early intervention of high-risk patients. This study demonstrated the possibility of collaborative research among different institutions using the common data model for precision medicine in lung cancer.

Authors: Zein Muhammad , @ Mat Zin Aizan Ali
Published: December 2023

Islamic integrated education was introduced by Muslim scholars since the Abbasiah Caliphate (750M-1258M). They promoted the same terminology i.e. integrated, integration, integral and integrative. In fact, national schools and Madrasah Indonesia use the same curriculum. However, national schools does not focus on Islamic education. Therefore, Madrasah plays an important role in disseminating islamic education. This article scrutinizes the concept and approaches of integrated islamic education in Indonesia. The qualitative research uses three methods of data collection which are documentation, interview and observation. Findings show that the concept and approaches in the integrated education will intertwine revealed and required knowledge. The application of the notion through a system of ‘Surat Keputusan Bersama Tiga Menteri’. Educationist suggest various approaches in the implementation. Firstly, an amalgamation. Secondly, an islamization of required knowledge. Thirdly, a combination of 50% revealed knowledge and 50% required knowledge. In conclusion, this article propose the third to be the future syllabus of national education in Indonesia in line with indonesians aiming for balanced national education and islamic education.

Disclosures of cyber exposure and audit fees: Evidence from ASEAN-4 banking
Authors: Karyani Etikah , Noveria Ana , Faturohman Taufik , Rahadi Raden Aswin
Published: December 2023

This study examines how external auditors respond to the disclosure of cyber exposures by commercial banks and how the COVID-19 pandemic period accentuates the effect of voluntary cyber risk disclosures (CRDs) on audit fees. Our study is a preliminary study analysing the CRD of the financial industry in emerging economies in the Association of Southeast Asian Nations (ASEAN). It extends Calderon and Gao’s (2021) study one step further with respect to the COVID-19 pandemic and identifies items by using manually collected keywords to extract CRDs. During the period 2015–2020, our samples are 63 listed banks in four ASEAN members (Indonesia, Malaysia, Thailand, and the Philippines — ASEAN-4) and the one-step generalized method of moments (GMM) is used. The study found that audit fees are significantly associated with CRD, including risk causes and impacts. Meanwhile, cyber risk governance disclosures affect audit fees after a one-year lag. This indicates that voluntary CRD is informative. Audit fees are also significantly affected by the interaction between CRD and COVID-19. It suggests that auditors incorporate the nature and content of client CRDs into their fee structure and directly support regulatory reporting requirements in emerging ASEAN countries to include cyber risk factors in annual bank statements.
Impact of Nontariff Measures and Border Crossing Time and Costs: The Case of Perishable Goods Trade in the Central Asia Regional Economic Cooperation Region
Authors: Ramizo Dorothea M. , Terada–Hagiwara Akiko
Published: December 2023

This paper explores the impact of at-the-border and behind-the-border measures on intraregional trade in perishable goods within the Central Asia Regional Economic Cooperation region. It presents empirical evidence that behind-the-border measures create more opportunities to improve intraregional trade in these goods. The authors used a Poisson Pseudo Maximum Likelihood estimation technique in a gravity model. Structural reforms in trade facilitation should consider enhancing sanitary and phytosanitary laboratories, aligning regulations with international standards, simplifying documentation, streamlining border processes, and fostering collaboration among customs and relevant agencies for perishable goods trade within the region.

Published: December 2023

The main trend in the development of sheep breeding in the last decade all
over the world has become a constant increase in the production of mutton.
This study was designed to study polymorphisms of genes GH, LEP, MSTN in two
breeds of North Caucasian Meat-Wool and Soviet Merino sheep in Russia, as
well as to identify potential single nucleotide polymorphisms (SNPs)
associated with growth traits to improve the genetic potential of sheep.
Parts of the GH, LEP, MSTN genes were amplified in North Caucasian Meat-Wool
and Soviet Merino sheep to identify SNPs by Sanger sequencing and using a
polymerase chain reaction protocol. These genotypes were correlated with
meat traits such as birth weight, growth rate, weaning weight. Genetic and
variance analysis of the data obtained was also carried out. Sheep age and
parity had a significant effect (p <0.05) on birth weight, growth rate and
weaning weight. Sequencing revealed missense mutations in the somatotropin,
leptin and myostatin genes in the structure of the sheep genome of the
studied breeds. Missense mutations of the GH gene (c.476G> A) and the LEP
gene (c.541G> T), as well as a synonymous replacement of the MSTN gene (c.
212C> A), were revealed. According to the results of studies in the North
Caucasian Meat-Wool sheep, three GHCC, GHCT, GHTT genotypes for the GH gene
and three LEPGG, LEPGT, LEP?? genotypes for LEP were identified. The studied
region of the MSTN gene in sheep of the North Caucasian meat and wool breed
turned out to be monomorphic. According to the results of studies in Soviet
Merino sheep, three genotypes GHCC, GHCT, GHTT for the GH gene, three
genotypes MSTN??, MSTN??, MSTN?? for the MSTN gene, two genotypes LEPGG,
LEPGT for the LEP gene were established. The analysis of associations showed
a significant effect (p <0.05) of the GH?? and LEPGT genotypes on the signs
of sheep growth. Interestingly, the presence of the T-allele in sheep of the
North Caucasian Meat-Wool breed tended to increase in weight during weaning
(+2.2 kg) both for the GH gene and for the LEP gene (+ 1.6 kg).
Interestingly, similar results were observed in sheep of the Soviet Merino
breed, where the missense mutation led to an increase in weaning weight (+
1.2 kg) for the GH gene and for the LEP gene (+1.3 kg). A synonymous MSTN
gene substitution does not lead to a substitution of the coding amino acid,
but may further lead to gene expression. The GH, LEP, and MSTN genes are
proposed markers for improving growth traits in meat-wool and wool sheep,
which will increase the ability to understand the genetic architecture of
the genes underlying SNPs that influence such traits.
Powerful Politicians, Political Costs, and Income Smoothing
Authors: Jung Sumi
Published: December 2023

This paper investigates whether and how firms receiving benefits through their connections to politicians use accounting discretion to mitigate the costs associated with negative publicity. I utilize a unique setting that captures the change in political costs arising from chairmanship appointments to influential U.S. Senate committees. Firms in the home state of a promoted officeholder often receive preferential treatment, drawing public scrutiny and incentivizing them to avoid reporting extreme earnings through income smoothing to reduce adverse political attention. Employing a difference-in-differences research design, I find evidence that home-state firms smooth their earnings throughout the officeholder’s tenure following a senator’s promotion to chairman or ranking minority member. Cross-sectional analyses demonstrate that these effects are stronger for firms anticipating higher political costs. Overall, this paper provides evidence of the political cost hypothesis, highlighting the role of political connections in shaping firms’ financial reporting strategies.

As professional secretory cells, β-cells require adaptable mRNA translation to facilitate a rapid synthesis of proteins, including insulin, in response to changing metabolic cues. Specialized mRNA translation programs are essential drivers of cellular development and differentiation. However, in the pancreatic β-cell, the majority of factors identified to promote growth and development function primarily at the level of transcription. Therefore, despite its importance, the regulatory role of mRNA translation in the formation and maintenance of functional β-cells is not well defined. In this study, we have identified a translational regulatory mechanism mediated by the specialized mRNA translation factor eukaryotic initiation factor 5A (eIF5A), which facilitates the maintenance of β-cell identity and function. The mRNA translation function of eIF5A is only active when it is posttranslationally modified (“hypusinated”) by the enzyme deoxyhypusine synthase (DHPS). We have discovered that the absence of β-cell DHPS in mice reduces the synthesis of proteins critical to β-cell identity and function at the stage of β-cell maturation, leading to a rapid and reproducible onset of diabetes. Therefore, our work has revealed a gatekeeper of specialized mRNA translation that permits the β-cell, a metabolically responsive secretory cell, to maintain the integrity of protein synthesis necessary during times of induced or increased demand.

Vaspin: A Novel Biomarker Linking Gluteofemoral Body Fat and Type 2 Diabetes Risk
Authors: Wang Harry Hezhou , Chong Michael , Perrot Nicolas , Feiner James , Hess Sibylle , Yusuf Salim , Gerstein Hertzel , Paré Guillaume , Pigeyre Marie
Published: December 2023

OBJECTIVE

To determine whether adiposity depots modulate vaspin levels and whether vaspin predicts type 2 diabetes (T2D) risk, through epidemiological and genetic analyses.

RESEARCH DESIGN AND METHODS

We assessed the relationship of plasma vaspin concentration with incident and prevalent T2D and adiposity-related variables in 1) the Prospective Urban and Rural Epidemiology (PURE) biomarker substudy (N = 10,052) and 2) the Outcome Reduction with Initial Glargine Intervention (ORIGIN) trial (N = 7,840), using regression models. We then assessed whether vaspin is causally associated with T2D and whether genetic variants associated with MRI-measured adiposity depots modulate vaspin levels, using two-sample Mendelian randomization (MR).

RESULTS

A 1-SD increase in circulating vaspin levels was associated with a 16% increase in incident T2D in the PURE cohort (hazard ratio 1.16; 95% CI 1.09–1.23; P = 4.26 × 10−7) and prevalent T2D in the ORIGIN cohort (odds ratio [OR] 1.16; 95% CI 1.07–1.25; P = 2.17 × 10−4). A 1-unit increase in BMI and triglyceride levels was associated with a 0.08-SD (95% CI 0.06–0.10; P = 2.04 × 10−15) and 0.06-SD (95% CI 0.04–0.08; P = 4.08 × 10−13) increase, respectively, in vaspin in the PURE group. Consistent associations were observed in the ORIGIN cohort. MR results reinforced the association between vaspin and BMI-adjusted T2D risk (OR 1.01 per 1-SD increase in vaspin level; 95% CI 1.00–1.02; P = 2.86 × 10−2) and showed that vaspin was increased by 0.10 SD per 1-SD decrease in genetically determined gluteofemoral adiposity (95% CI 0.02–0.18; P = 2.01 × 10−2). No relationships were found between subcutaneous or visceral adiposity and vaspin.

CONCLUSIONS

These findings support that higher vaspin levels are related to increased T2D risk and reduced gluteofemoral adiposity, positioning vaspin as a promising clinical predictor for T2D.

Authors: Khofifah Rike Farikha , Savitri Dian
Published: December 2023

The predator-prey model is the mathematical model that describes the interaction behavior between prey and predator. This research discusses the modified Leslie-Gower model by considering the cannibalism behaviors of the prey that contains Holling type I response function, which is a predator with passive characteristics. The stability analysis stage includes determining the system's solution in the form of an equilibrium point, analyzing the local stability of each equilibrium using eigenvalues, and numerical simulation to synchronize the analysis results. Numerical simulations visualized in phase portraits with Python software. The results of the local stability analysis of the system obtained four equilibrium points, namely, equilibrium points  are unstable while is asymptotically stable with certain conditions. The results of numerical simulations show that only the equilibrium point  which is asymptotically stable when the environment carries capacity parameters (e=2.1). Meanwhile, when e=2.878 then, only is asymptotically stable. In this research also using two different initial values, it is concluded that whatever the initial value used, the system solution always converges to the equilibrium points  dan . Changes in environmental carrying capacity affect the dynamics of system solutions.
Unravelling Tool Edge Trajectory Patterns: Implications on Surface Roughness in End Milling Process
Authors: Yusof Fatiha Naziera , Ismail Mohd Fauzi
Published: December 2023

This study examines the effect of end milling on surface roughness in modern manufacturing. Mathematical equations simulate and analyse the tool edge trajectory of a two-flute end mill during end milling. The results are refined using MATLAB and watershed segmentation. An aluminium alloy flat bar is end-milled using a CNC milling machine for the experimental phase. Optical 3D surface measurements provide roughness data for analysis. The study shows that higher spindle speeds produce smoother surfaces with improved surface quality. The correlation matrix analysis highlights the significance of spindle speed in shaping surface roughness, and tool trajectories are associated with softer surfaces at elevated speeds for the spindle speed ranging between 1000 to 3500 rpm. The study offers valuable insights into the complex relationship between tool edge trajectories and surface roughness.

Published: December 2023

OBJECTIVE

To describe the signalment, clinical findings, presumptive or definitive diagnosis, and outcome in cats with central cord syndrome (CCS).

ANIMALS

22 cats.

CLINICAL PRESENTATION

Cats evaluated for CCS at 7 referral hospitals between 2017 and 2021 were included. Information retrieved from medical records included signalment, physical and neurological examination findings, diagnostic investigations, definitive or presumptive diagnosis, treatment, and follow-up.

RESULTS

Median age at presentation was 9 years. Two neuroanatomical localizations were associated with CCS: C1-C5 spinal cord segments in 17 (77.3%) cats and C6-T2 spinal cord segments in 5 (22.7%) cats. Neuroanatomical localization did not correlate with lesion location on MRI in 8 (36.3%) cats. The most common lesion location within the vertebral column was over the C2 and C4 vertebral bodies in 6 (27.2%) and 5 (22.7%) cats, respectively. Peracute clinical signs were observed in 11 (50%) cats, acute in 1 (4.5%), subacute in 4 (18%), and chronic and progressive signs were seen in 6 (40.9%) cats. The most common peracute condition was ischemic myelopathy in 8 (36.3%) cats, whereas neoplasia was the most frequently identified chronic etiology occurring in 5 (22.7%) cats. Outcome was poor in 13 (59%) cats, consisting of 4 of 11 (36.6%) of the peracute cases, 3 of 4 (75%) of the subacute cases, and 6 of 6 of the chronic cases.

CLINICAL RELEVANCE

Central cord syndrome can occur in cats with lesions in the C1-C5 and C6-T2 spinal cord segments. Multiple etiologies can cause CCS, most commonly, ischemic myelopathy and neoplasia. Prognosis depends on the etiology and onset of clinical signs.
Rural Landscapes and Affective Encounters in Radu Muntean’s Film, Întregalde
Authors: Sándor Katalin
Published: December 2023

The paper discusses Radu Muntean 2021 film, Î
ntregalde focusing on the representation of rural landscapes and the encounter between different social classes. The film marks multiple displacements within the director’s oeuvre, epitomized as “the chronicler” of the middle class in contemporary Romanian cinema. The spatial displacement from middle class urban spaces towards mountain and rural areas and the shift from the distant picturesqueness of landscape to the experience of landscape as dwelling, as inhabited and sensed environment mediated through textural images enables unsettling embodied, affective encounters both with the natural environment and between different social classes. In this way, the film addresses the question of class differences and lays bare the socio-economic inequalities between the urban middle class and the countryside without reducing rural characters to clichéd figurants in a picturesque or sombre countryside decorum. The film’s critical reflection on a form of occasional humanitarian aid and middle class philanthropy does not relativize the concept of charity, altruism and help but rather points to the growing gap of social inequalities (and the crisis of care) in the context of contemporary capitalism.1

The main purpose of this study is to evaluate the effect of curing method on the compressive strength of waste glass powder as a supplementary cementitious material. This work presents an experimental study on the physico-mechanical characterization of waste glass powder (GP) as partial replacement of special cement (Algerian cement without additions CPA) based high performance cementitious material, varying the percentage of GP by 10%, 20% and 30% (by weight of cement), the curing methods: water curing at 20± 2 °C and heat curing by under accelerated drying in an oven at 100 °C (stoving). Half of the mortar samples 40x40x160 mm were treated with stoving just after demolding then kept in the open air, the other half was kept in fresh water in order to evaluate their sustainability and index of Poozolanic Activity (I) at different ages: 7, 28, 90 and 365 days. The compressive strength results showed that there is an increase in compressive strength with the increase in age of the two curing methods but the strength of all mixtures which have been stoved is inferior to those of the same mixtures preserved in fresh water at different ages. The best rate of replacement of the cement by GP is 20% following the results obtained for the compressive strength and Poozolanic Activity Index I.

A recently created cementing substance noted for its remarkable qualities is reactive powder concrete (RPC). It incorporates fine quartz sand, crushed quartz, silica fume, a low water-to-cement ratio, and a high percentage of Portland cement. In RPC, fine quartz sand completely takes the role of coarse aggregate. This study examines the effects of high-temperature curing on RPC strength while concentrating on the manufacture of RPC in Pakistan using locally accessible materials. In specifically, a compressive strength of more than 142 MPa is one of the desirable hard qualities that must be attained as the main goal. The study uses a variety of test mixtures and curing methods, including heat curing. The major emphasis is on mechanical properties such as compressive strength, split cylinder strength, and flexural strength. The study also investigates how the mechanical properties of RPC are affected by various steel fiber concentrations and curing conditions. With varying quantities of steel fiber and silica fume, more than 100 experimental mixtures are created. In comparison to silica fume levels, which range between 25% and 35% by weight of cement, steel fiber concentrations range from 0% to 3% by total volume. The results demonstrate the effects of curing at 60°C, 70°C, and 90°C. Notably, after 28 days of curing at 90°C, a compressive strength of 142 MPa is attained, suggesting a general rise in compressive strength across all curing methods with curing age.

The rising levels of air pollution in the industrial environment necessitate its monitoring near the sources. The green wall around the industries is a novel and popular to mitigate the impact of Particulate Matter (PM). Such industrial mitigation cannot be monitored through a limited quantity AQ monitoring station at ground level. This paper demonstrates the application of drone aided particulate matter monitoring system to measure the above-ground level PM levels. The drone-aided AQ monitoring system was employed near the thermal power plant to calculate the attenuation factor potential due to the plantation of a green bamboo belt. The wind rose was plotted to understand the wind pattern and dispersion direction of the PM. The dust suppression due to the green wall of the bamboo is calculated using a drone-enabled PM sensor module. The PM (Particulate Matter) data at the ground level was 39 % low compared to the upper height. The PM concentration was significantly high at the height of 30 m Above Ground Level (AGL). The bamboo plant plays a crucial role in dust suppression. The overall results pointed out that the calibrated, lightweight portable drone-aided sensor monitoring system can be reliable for monitoring source-specific industries.

The present paper focuses on a study model of a trithermal absorption machine, operating at H2O/LiBr couple, powered by a planar solar collector. Therefore, the mathematical model is based on the principles and laws of thermodynamics as well as the heat and mass transfer equations, expressed for the refrigeration cycle. In fact, the results of the complete numerical simulation of the machine, developed within the framework of this study, allow predicting the performances of this type of installation according to the various parameters as well as the operating temperatures and the flow rate in the absorber.
The Concept of Permanent Education – Paradigmatic Approaches
Authors: Eși Marius-Costel
Published: December 2023

When we speak about the concept of “permanent education”, our attention focuses on comprehensive and broad approaches to the instructive-educational process that go beyond, or, at least, should go beyond what we call or we mean by the traditional boundaries of school and formal education. In fact, the lifelong education constitutes sine qua non a continuing process of learning and development throughout life, a process that takes place in various contexts and at different stages of our lifetime. In this context, we can state that the permanent education must be in agreement with everything that means, on the one hand, the educational market, and on the other hand, the economic market corroborated with the idea of the labor market.

We believe that such an assumption is justified by the very demands and new orientations of the labor market as well as by the need of the human being to continuously develop himself in relation to himself and also to everything that is around him. Such a reform of the educational society (Comenius) and of the human being (Dewey), in relation to what the continuous development entails, only brings into discussion a series of ideas such as the continuous learning, the (self) exploration, the personal development and so on.Therefore, the analysis of this paper will focus on the one hand, on the paradigmatic approach to the concept of “permanent education” (from a diachronic and synchronic viewpoint), and on the other hand, on the analysis of specific features of some paradigms related thereof. Thus, we will try to show that its benefits and impact may vary according to individual context and needs.
Learning Management System (LMS) for Academic Inclusion and Learning Agency: An Interpretive Review of Technoprogressivism in ODL Instructional Technology Policy

Literature frequently describes how ineffective implementation of instructional policy frameworks can make distance learning a lonely and unrewarding academic pursuit, characterized by high student drop-out rates, high failure rates and academic exclusion. In trying to mitigate this catastrophe, academic departments in distance learning institutions utilize learning management systems (LMSs) to stimulate students’ learning experiences. In keeping with techno-progressivism, the researchers (and authors of this paper) turned to extant documentary policy and literature to review – qualitatively – how the University of South Africa’s (Unisa’s) Open Distance Learning Policy (ODLP) promotes academic inclusion and learning agency as cornerstones of student success and social justice, especially in an unequal society like South Africa. The findings revealed the following: 1) Unisa’s ODLP position has the impetus to influence the deployment of the LMS to promote academic inclusion; 2) Practical means of promoting inclusion were mirrored in the provision of manual or electronic learning material, computer laboratories and free internet connectivity in regional centres across all nine provinces of South Africa, as well as in the provision of laptops for National Student Financial Aid Scheme (NSFAS)-funded students, 30 gigabytes of free monthly mobile data to all students, and assistive technologies for students with disabilities; 3) Practical utilization of an LMS to foster self-regulated learning occurred through problem-based individual activities supplemented by asynchronous demonstrative learning material (e.g. audio, video), while collaborative learning agency was enabled through e-tutoring, which afforded students the opportunity to interact with e-tutors and their peers about the learning content; 4) Drawbacks in the use of the LMS stemmed from the insufficiency of assistive learning technologies that are required for students with disabilities to participate fully in online learning, and a corpus of students’ irregular attendance at and participation in e-tutoring discussions and their projection of a negative attitude towards the e-tutors.
