ВИКОРИСТАННЯ ТЕХНОЛОГІЙ ВІРТУАЛЬНОЇ РЕАЛЬНОСТІ ДЛЯ ВИВЧЕННЯ ПРИРОДНИЧИХ НАУК У ПОЧАТКОВІЙ ШКОЛІ
Authors: Гуркова Тетяна
Published: February 2025

У статті розглянуто актуальні аспекти впровадження віртуальної реальності в початковій ланці. Визначено, що VR для педагогів є викликом. Наразі це питання – одне із пріоритетних вимог сучасності. Учні початкової школи в реаліях сьогодення не мають можливості моделювати, маніпулювати з предметами, досліджувати, експериментувати, подорожувати в реальному часі. Перехід на дистанційне навчання поставив перед педагогами нове завдання – опанувати новітні технології, зокрема VR в початковій освіті. Упровадження передових досягнень країн світу поширюється теренами НУШ. Віртуальна реальність на заняттях у початковій школі активно залучає до опанування новими знаннями здобувачів освіти, мотивує, зацікавлює, створює ситуацію успіху. Однак, попри численні переваги, цифровізація освіти супроводжується значними недоліками. Серед них – різниця у забезпеченні технікою, доступність та швидкість інтернету в сільських школах. Для підвищення ефективності впровадження цифрових технологій (VR) в освітній процес необхідно здійснювати підготовку викладачів до роботи у цифровому середовищі, розробити нові методики навчання, знайти оптимальний баланс між цифровими й традиційними методами навчання, а також забезпечити супровід з боку держави та інститутів післядипломної освіти, зокрема.

Model Pengoptimuman Portofolio Mean-Variance dan Perkembangan Praktisnya
Authors: Setiawan Ezra Putranda , Rosadi Dedi
Published: February 2025

Many research about portfolio optimization in Indonesia still uses the ‘original’ mean-variance model as proposed by Markowitz more than 60 years ago. This article reviews the development and modification of the Markowitz’s mean-variance model, especially that dealing with real stock-market features, which could help the investor to create their own portfolio. There were several real-stock market features that implemented in the modification of mean-variance portfolios optimization models, such as the minimum transaction lots, the transaction cost, the cardinality constraint, the weight constraint, and the sectoral constraint. To implement these features, several heuristic methods were used to obtain the optimal portfolio weight, such as genetic algorithm, Tabu search, bee colony algorithm, particle swarm algorithm, and simulated annealing. These methods become alternative to the mathematical programming method.

Advancing Autonomous Aerial Refueling with Deep-Neural-Network-Based Image Segmentation
Authors: Mwaffo Violet , Miller Dillon , Costello Donald H.
Published: February 2025

Integrating uncrewed aerial systems (UASs) into United States Navy carrier air wings will most likely require the implementation of autonomous aerial refueling (AAR). AAR will boost operational flexibility, range, and endurance. However, the current challenge lies in achieving the necessary safety of flight certification for AAR. This study introduces a deep neural network model trained with a limited dataset from actual flight test footage to accurately identify and track segments of the refueling drogue. Unlike traditional object detection methods, this model employs instance segmentation to dynamically outline the drogue’s shape. This advancement lays the groundwork for future models capable of predicting the drogue’s shape and position, even under challenging environmental conditions and potential false detections. The model’s efficacy is evaluated using video footage from KC-130 refueling operations, encompassing diverse background scenarios and noise levels. The model demonstrates robust performance, achieving a high mean average precision of 0.971 at an intersection over union threshold of 0.5. By addressing real-world challenges of image quality and varying light conditions, this research aims to significantly advance the reliability and sophistication of AAR technologies.
Comparative Study of Various Strategies for Multirotor UAV Propeller Icing Mitigation
Authors: Samad Abdallah , Dhulipalla Anvesh , Hu Hui
Published: February 2025

An experimental study was conducted to compare various strategies for UAV propeller icing mitigation. With a propeller model with an untreated hydrophilic blade as the comparison baseline, three icing protection systems (IPSs) were evaluated systematically: 1) a passive method with the propeller blade coated with a super-hydrophobic surface (SHS) coating; 2) an active IPS design to forcefully heat the entire blade surface; and 3) a hybrid IPS design with only limited surface heating along the blade leading edge and the SHS-coated blade. While the passive method with the SHS-coated blade was found to be only marginally effective under the glaze icing condition, it became ineffective or even further deteriorated the propeller performance under the mixed and rime icing conditions. While the active IPS design to forcefully heat the entire blade surface was found to be able to prevent ice accretion on most of the blade surface, some minor “ice crowns” were still observed to accrete near the blade tip. The hybrid IPS design was demonstrated to keep the entire blade surface ice-free under all the icing conditions with substantially less power consumption (i.e., [Formula: see text] power saving), rendering it a compelling UAV propeller icing mitigation strategy.
Longing for Love: Eros and National Belonging in Three Novels by Rayda Jacobs
Authors: Moolla F. Fiona
Published: February 2025

The female Muslim descendant of Cape slavery is a key figure in the work of South African writer, Rayda Jacobs. Three of her novels, in particular, seem to track the social and political genealogy of the female Muslim descendant of slaves, namely, Eyes of the Sky (1996), The Slave Book (1998), and Sachs Street (2001). These novels trace, through the subjectivity of the female Muslim slave, the emergence of the South African nation from its origins at the Cape, through the hinterland, to its contemporary borders. The novels foreground the personal relationship of romantic love, which, of all the personal relationships, is the most volatile and dynamic, producing unexpected transformations. Love, which produces a child from the erotic encounter in Eyes of the Sky, and social union through marriage in The Slave Book, is presented as having the potential to transcend racial, class and religious boundaries in the colonial state. We see in the declining apartheid state presented in the third novel, Sachs Street, that the national allegorical potential of eros finally is not fully realised, leading to a reconceptualisation of romantic love in a transnational frame, centred nonetheless in Cape Town, South Africa. As much as these novels are historical, since they are written post-1994 reflecting the contemporary concerns of its author, they present a singular vision of the place of the female Muslim descendant of slaves in the South African nation, where the postcolonial nation is implicitly conceptualised as a white-dominated derivative European nation state.
Deobandi Orientated Dār al-‘Ulūms in South Africa, Deobandiyyat: Background, Typology, and Diverse Ideological Conceptualisations Among ‘Ulamā’
Authors: Dockrat Ashraf
Published: February 2025

A number of South African Muslims consider themselves Deobandi by affiliation. “Deobandiyyat” (allegiance to the thought of the Darul ‘Ulūm in India and its founders) was promoted and found expression early in South African society. It was especially the Jamiatul Ulama groupings and the dār al-‘ulūms that promulgated and continues to entrench Deobandi thinking in society. In 1973 the first dār al-‘ulūm was established in South Africa. Here traditional scholars were trained to serve the religious community of the country. Ever since, the number of these traditional institutions has mushroomed. They have commonalities and are divergent in some ways. Each has its own catchment area and ideology and as such represent the diversity present in the South African Muslim community. This article explores the ideological congruences and diversions of the various dar al-ulūms in South Africa and shows how these are tied to the broader theological debates within the community. This article also examines some of the ramifications of these debates.
Sheikh Mohamed Badamana and Radio-Based Fatwas (Legal Verdicts) as a Learning Tradition in Kenya
Authors: Mraja Mohamed Suleiman
Published: February 2025

In the 1980s, the Kenya Broadcasting Corporation (KBC), and Radio Taifa (National Radio), hosted a 30-minute programme entitled Uliza Ujibiwe. The presenter was Mohamed Salim Badamana, an associate professor of Veterinary Medicine. In this radio programme, the Kenyan public (both Muslims and non-Muslims) would pose questions in writing on issues touching on Islam and the presenter would give a fatwa-sort of response. Given his academic background, this raises the question: Was his participation in a religious program challenging the conventional religious authority held by the traditional ‘ulama (Islamic scholars) in Kenya? Given its wider reach, the radio is an effective medium for knowledge production, interpretation and dissemination. Arguably, the use of electronic media can be a vehicle for blunt religious indoctrination and a means to disseminate positive universal human values across linguistic, racial, religious and social differences that in turn help in strengthening multicultural, multi-religious nations (Adnan 2010; Laura et al. 2019). Undoubtedly, Badamana’s radio programmes provided pertinent answers to a wide array of questions raised by the Kenyan public, both Muslims and non-Muslims alike. What purpose did Badamana’s radio sessions serve in the Kenyan context? What sort of issues were of great interest to the audience and why? Therefore, my study analyses the contribution of Badamana to Muslim knowledge creation and dissemination in Kenya, based on the findings of a discourse analysis of selected audio recordings of Uliza Ujibiwe. While the programme is defunct, Badamana, appropriated the national radio to give fatwas on a wide range of issues, an emerging vista, way beyond the hitherto common mosque-darsas (study sessions) and textual writing platforms of the local ‘ulama (Islamic scholars).
Yet Again Qurʾān 4:34: A Syntax and Semantics-Rhetoric Reading
Authors: Mathee Muhammad shahid
Published: February 2025

The qurʾānic passage “… and hit them” (Qurʾān 4:34) causes many modern Muslim believers consternation. They problematise Qurʾān 4:34 and its interpretation for affording husbands a right to exercise violence on women’s bodies. They foreground the verb “hit” in the imperative mood. This article proposes a different approach to reading Qurʾān 4:34. It foregrounds the nouns in the passage, namely husbands and wives, to offer a reading of Qurʾān 4:34 that is fundamentally concerned with the character and behaviour of husbands and wives who think, speak, and behave in everyday life and not giving apparent commands to husband to hit their wives whose nuŝūz they fear. To shift the focus from the action “hit” in the imperative mood to the character of husbands, the article draws on a hermeneutic of ibn ʿArabī that views some prescriptive commands in the Qurʾān not as commands, but rather as statements in the imperative mood.
Upotocznienie języka jako sposób budowania narracji w biografii sportowca (na materiale biografii Roberta Lewandowskiego)
Authors: PAŁUCKA-CZERNIAK IWONA
Published: February 2025

The analysis serves to present the communication strategy used in building a narrative in the athlete’s biography, which involves changing the official language to an unofficial one, saturating the message with colloquialism and commonness, andintroducing elements of live speech into the written text. The phenomenon is presented with the example of the biography of the contemporary Polish footballer, Robert Lewandowski, written by Paweł Wilkowicz. The analysed implementation of the biography genre shows a cross-border approach to genological determinants. The text has muddled and blurred genre features. It concerns a living person and is created with his participation. It combines an objective, external narrative with a subjective, internal approach. The latter strategy allows for a purposeful, reflective definition of one’s own identity, its construction and creation. The difference, duality and contradiction between genres is consolidated in the text and language, and allows for reconstructing various strategies of talking about the book’s hero and his fate. Making the language of biography colloquial by saturating it with elements of live speech, lexis belonging to an unofficial variety of the language, colloquialism and expressiveness, and finally ensuring a smooth transition in the narrative from the language of the people interviewed to the language of the narrator, are related to thespecificity of a communicative community, and to the idea of which the biography is being written. It also results from the use of an interview as a form of obtaining information by a journalist, which contributes to the introduction of colloquiality and the abandonment of the official nature of the message.

Published: February 2025

Objectives

Cardiovascular disease (CVD) is regarded as a leading cause of premature mortality and morbidity among individuals with chronic kidney disease (CKD). There is a high burden of cardiovascular complications in CKD patients, necessitating an integrated approach for targeted management of cardiovascular complications among CKD patients. The objective of this study was to evaluate the prevalence, nature, and risk factors of cardiovascular complications among CKD patients in a tertiary care center in Nepal.

Materials and Methods

It is a prospective and cross-sectional study conducted for 1 year (April 2020–2021). We recruited a total of 60 patients, meeting the criteria. Comprehensive patient histories, thorough physical examinations, potential risk factors for cardiovascular complications, echocardiographic, and laboratory data were collected. Statistical analysis was performed using the Statistical Package for the Social Sciences version 25.

Results

Among all, the predominant cardiovascular complication was valvular heart disease (VHD) (71.67%), with mitral regurgitation being the most prevalent (58.33%). Other complications included left ventricular diastolic dysfunction (66.67%), left ventricular hypertrophy (LVH) (53.33%), left ventricular systolic dysfunction (21.67%), pericardial effusion (15.00%), and global hypokinesia (11.67%). Significant comorbidities included anemia (100%), hypertension (HTN) (91.67%), diabetes mellitus (DM) (56.67%), and dyslipidemia (58.33%). Notably, 40.00% were smokers, 38.33% reported alcohol consumption, 21.67% were obese, and 13.33% were underweight.

Conclusion

Our study highlights the substantial impact of cardiovascular complications among CKD patients in Nepal. We found that VHD and LVH are particularly prevalent, underscoring the urgent need for early detection and targeted management strategies in clinical practice. The strong association with common comorbidities such as anemia, HTN, DM, and dyslipidemia further emphasizes the intricate relationship between renal and cardiovascular health in this population. Thus, these findings provide valuable insights into the cardiovascular and general healthcare challenges faced by CKD patients in our setting, urging for integrated care approaches to improve outcomes and enhance patient care.

Purpose. To conduct a comprehensive assessment of the condition of the ocular surface, including data from subjective and objective methods for the study of dry eye syndrome (DES), in patients who plan to underwent refractive surgery.

Material and methods. A comprehensive assessment of the condition of the ocular surface of 30 patients (30 eyes) scheduled for Femto Laser-Assisted in Situ Keratomileusis (FemtoLASIC) surgery with initially no subjective signs of dry eye syndrome and 30 patients (30 eyes) scheduled for surgery using refractive small incision lenticular extraction technology (SMILE) with initially no subjective signs of dry eye syndrome was carried out.

Results. Preoperative results of objective methods of examination of the ocular surface do not correspond to the preoperative results of subjective methods of investigation of dry eye syndrome in patients who plan to underwent refractive surgery. In both groups, there is no reliable correlation between the data of the general standard ophthalmological objective methods of screening for dry eye syndrome and the true condition of the ocular surface.

Conclusion. Thus, a comprehensive diagnostic approach to assessing the condition of the ocular surface, based on subjective and objective methods of studying dry eye syndrome, forms a holistic view of the homeostasis of the ocular surface in patients who plan to underwent refractive surgery, followed by the development of an algorithm for choosing the optimal technology for each patient.

Key words: tear film, ocular surface, dry eye syndrome, keratorefractive surgery.
An in vitro Approach: Cholesterol Assimilation and Probiotic Characterization of Enterococcus faecium (JD 9) isolated from fermented foods
Authors: Allavarapu Dharma Teja , Cherukuri Pavana Jyothi
Published: February 2025

High plasma cholesterol levels can cause cardiovascular diseases (CVD) in humans and lactic acid bacteria (LAB) were found to be fine-tuned in maintaining cholesterol homeostasis and were considered helpful for life due to their significant impact on human and animal health when taken orally. This bacterial interaction leads to the deconjugation of bile salts by the BSH enzyme and the assimilation of cholesterol, which are particularly important. This study examined the probiotic characterisation and cholesterol assimilation by lactic acid bacteria isolated from fermented foods along with reference strains (L. acidophilus MTCC 10307 and L. rhamnosus MTCC 1408). Isolate was identified as Enterococcus faecium JD9 by 16S rRNA. All strains in this investigation can enhance the tolerant to low pH, bile salt and simulated gastric juice. It has shown catalase-negative, gram-positive, non-haemolytic activity, bile salt hydrolase activity, sugar fermentation, autoaggregation, antibiotic sensitivity and assessment of cholesterol assimilated from media.

HPLC was used to quantify the assimilated cholesterol. All strains demonstrated a remarkable capacity to assimilate cholesterol with and without bile salt, reaching a rate of cholesterol assimilation of Enterococcus faecium JD9 (78% and 96.52%), Lactobacillus rhamnosus MTCC 1408 (77% and 92.34%) and Lactobacillus acidophilus MTCC 10307 (76% and 88.45%). The results indicate that the strain isolated from fermented food has the potential to be employed as probiotics and alternative therapeutics due to their capacity to bile salt hydrolase and to reduce cholesterol levels.
Increased yield and essential oils content in rhizomes of white turmeric (Curcuma aromatica Salisb.) by plant growth regulators
Authors: Tran T.T. Hien , Nguyen H.B. Vinh , Tran Thanh Thang , Đo Thuong Kiet
Published: February 2025

White turmeric is a rhizome plant that contains essential oils and many secondary metabolites having medicinal effects. In order to improve rhizome yield and essential oil content, this study investigated the response of plant growth regulators to the growth stages of white turmeric plants grown from mother tubers in an experimental garden. After 2 weeks of treatment, the rhizomes were measured for fresh and dry weight, rhizome length, sugar and starch content. Rhizome yield, number of rhizomes per plant and essential oil content were measured after 24 weeks of treatment. The results showed that fresh and dry weight as well as sugar content in white turmeric rhizomes at the resting shoot stage increased after 2 weeks of treatment with concentrations of 2 mg/L NAA and 10 mg/L BA, while this occurred at the elongated shoot stage when treated with BA 10 mg/L and at the seedling stage when treated with 20 mg/L GA3 or 10 mg/L BA to compare with the control and other treatments.

However, at the seedling stage, the rhizome length when treated with 20 mg/L GA3 was longer, so the fresh weight of the rhizome was more when treated with 10 mg/L BA. 24 weeks after the combined treatment of plant growth regulators (treated with 10 mg/L BA at week 0, treated with 10 mg/L at week 2 and treated with 20 mg/L GA3 at week 4), the rhizome yield per plant, the number of rhizomes and the essential oil content increased significantly compared to the other treatments. The effects of plant growth regulators on the yield and accumulation of white turmeric rhizomes are also discussed.
Isolation and speciation of Acinetobacter species from various clinical samples and their antibiogram
Authors: Nayaki Vidyaa S. , Mariraj Jeer
Published: February 2025

Acinetobacter species are Gram negative nonfermentative bacteria commonly present as free living saprophytes. Acinetobacter has emerged as an important nosocomial pathogen involved in outbreaks of hospital infections. The ubiquitous organism has been recovered from hospital environment, from colonized or infected patients or from staff. The emergence of multi drug resistance poses a significant challenge in identifying and treating this organism. Retrospective study was carried on clinical samples received from various departments. Acinetobacter isolates were identified and speciation was done by using biochemical methods and antibiotic sensitivity pattern of these isolates was studied.

A total of 210 Acinetobacter species were isolated from various clinical samples, commonest being urine samples followed by sputum, blood, pus samples. The most common species isolated were: A.baumanii (79%), A.iwoffi (17%), A.haemolyticus (2%) and A.junni (2%). Resistant pattern to various drugs was Amoxyclauv 83.6%, Imipenam 48.3%, Piperacillintazobactum 42.6%, Amikacin 58%, Gentamicin 66%, Ceftazidime 72%, Cefotaxime 68%, Ciprofloxacin 76%. In the present study, the prevalence of Acinetobacter from various samples and its antimicrobial susceptibility pattern was studied. Increased emergence of multi drug resistant strains is an important health concern as it poses a challenge in treatment. A surveillance study is required to know about the strains prevailing in the particular geographical locations and its antimicrobial sensitivity pattern.
Moral concerns about artistic activity
Authors: Bertinetto Alessandro
Published: February 2025

Une grande partie du débat contemporain sur l’art et la morale porte sur les conséquences comportementales de l’expérience des œuvres d’art, sur la dépendance ou l’indépendance entre la valeur esthétique et la valeur morale des œuvres d’art, et se demande si des défauts ou des mérites éthiques des œuvres d'art devraient également être considérés comme des défauts ou des mérites esthétiques (et vice versa). Ici, je vais me concentrer sur un autre sujet, bien qu’il soit lié au premier. Je vais examiner si les artistes ont des devoirs envers l’art lui-même, comme Luigi Pareyson l’a affirmé dans son Estetica. Teoria della formatività (1954). En d'autres termes, je vais poser la question de savoir si la poursuite de la réussite artistique nécessite, entraîne ou peut causer une sorte de position morale envers l’activité artistique. Je suggère que la notion d’authenticité comprise non seulement comme une obligation ou un devoir, mais plutôt comme une vertu, peut être utile à cet égard.

Le soutien aux capacités d’autosoins des personnes atteintes de BPCO par les infirmiers à domicile dans le cadre du Prado : une étude qualitative
Authors: GAUTIER Marlène , GARRY-BRUNEAU Mathilde
Published: February 2025

La BPCO est une maladie chronique qui induit pour les personnes des autosoins quotidiens afin d’avoir une qualité de vie satisfaisante. Le Prado BPCO propose des interventions à domicile à la suite d’une hospitalisation afin d’autonomiser la personne dans son suivi de la maladie.Objectif : Décrire les pratiques des infirmiers à domicile qui permettent de soutenir les autosoins des personnes atteintes de BPCO dans le cadre du dispositif du Prado.Méthode : Cette étude s’est positionnée sur un devis de recherche qualitatif phénoménologique. Des observations associées à des entretiens d’explicitations ont été réalisées lors de séances Prado BPCO auprès de cinq infirmiers exerçant à domicile, soit en libéral soit en centre de soins. Les données recueillies ont été retranscrites, codées puis croisées à travers une grille d’analyse construite à partir du cadre conceptuel de la théorie des autosoins dans la maladie chronique de B.Riegel.Résultats : La majorité des soins liés à la maladie chronique BPCO sont dispensés par les personnes elles-mêmes.

Cationic surfactants are widely used in various applications, making their environmental behavior a critical concern. However, soil sorption studies at environmentally relevant submicromolar concentrations remain scarce. In this study, sorption isotherms of five benzalkonium compounds (BACs) and two dialkyldimethylammonium compounds on kaolinite under dilute conditions were determined using a conventional batch-shaking and centrifugation method. In addition, the feasibility of using a polyacrylate (PA) fiber passive sampling method to measure freely dissolved surfactant concentrations in kaolinite suspensions was investigated. All kaolinite sorption isotherms were nonlinear (Freundlich exponent, 0.51–0.68), even at low surfactant concentrations (< 0.2% of the cationic exchange capacity), suggesting high sorption site heterogeneity. The kaolinite–water sorption coefficients (Kkao/w) of BACs in an isosteric condition increased with alkyl chain length; however, the incremental increase in log Kkao/w per -C2H4- unit varied with chain length, further indicating heterogeneous sorption sites. Kaolinite sorption isotherms measured using passive sampling were comparable to those measured by direct sampling. PA fiber fouling by kaolinite particles and the high isotherm nonlinearity of PA sorption at high concentrations were identified as major sources of error.

Hybrid organic-inorganic (HOI) antimony and bismuth halides exhibit diverse structural features and have been studied intensely for their promising electronic and optical properties. There are well-explored structure-property relations for these materials. However, a thorough understanding of synthesis routes and templating effects is lacking, turning their targeted synthesis into an open challenge. In this study, we assemble a literature data set of established HOI material candidates and train an explainable machine learning (ML) classification model to explore the templating effects in more detail. With a classification accuracy upwards of 70%, our model is effective in predicting HOI structure types based on the reactants and points out several structural and electrostatic design features for the organic cation that influence the inorganic substructure most strongly. We further demonstrate the validity of our classifier on 9 newly synthesized members of this materials class and propose incremental learning routes to expand the model in future research.
A Compartmentalized Model of Multiphase Chemical Kinetics
Authors: Prophet Alexander , Wilson Kevin
Published: February 2025

There are significant challenges in predicting multiphase chemical kinetics due to the complex coupling of reaction and mass transport across a phase boundary (i.e. interface). Here we describe a framework for predicting multiphase kinetics that embeds the elementary kinetic steps of reaction, solvation and diffusion into a coarse grain spatial description of two phases. The model is constructed to bridge the short-timescale interfacial dynamics observed in molecular simulations with the longer timescales observed in kinetic experiments. A simple set of governing differential equations is presented, which when solved numerically or analytically, yield accurate predictions of multiphase kinetics in microdroplets. Although the equations are formulated for gas-liquid reactions, the underlying conceptual framework is general and can be applied to transformations in other two-phase systems (solid-liquid, liquid-liquid, etc.).

Published: February 2025

Anion exchange membranes (AEMs) are integral to fuel cells and water electrolysis systems but suffer from poor durability under alkaline conditions. Ether cleavage is an important failure pathway of poly(arylene ether) based AEMs that compromises both mechanical stability and ion transport. While this degradation pathway is often studied in terms of polymer fragmentation, the role of newly formed hydrophilic groups has been largely overlooked. We show that polymer scission leads to reduced mechanical rigidity, while the introduction of hydrophilic groups partially mitigates this loss. Under alkaline conditions, phenoxide groups formed during ether cleavage neutralize the polymer cations, leading to a previously unreported loss of ion exchange capacity (IEC). This IEC loss mechanism exacerbates the reduction in ionic conductivity, emphasizing the severity of ether cleavage as a degradation pathway. Recognizing that ether cleavage introduces significant chemical changes beyond polymer fragmentation provides critical insights into its interplay with other degradation mechanisms, such as the direct reduction of cationic sites by E2 and SN2 and provides molecular-level interpretations for the concurrent effects of polymer scission and increased hydrophilicity on membrane performance.

The discovery of molecules in the interstellar medium (ISM) plays a key role in understanding prebiotic chemistry. Relatively few (~250) molecules have been confirmed in the ISM, and detecting additional species is crucial for expanding our knowledge of astrochemical processes. We present a strategy for predicting possible prebiotic molecules in the ISM that combines machine learning and high-accuracy quantum chemistry calculations. Using a reaction dataset of over 153,000 possible combinations of known interstellar molecules, we applied a machine learning model to estimate reaction energy barriers and identify those with low or zero barriers that are most likely to occur in the ISM. From this screening process, 24 molecules were identified, five of which have already been observed in interstellar space. For the remaining 19 molecules, we conducted density functional theory (DFT) and coupled cluster theory calculations to determine the most stable conformers, spectroscopic parameters, and predict their detectability through spectroscopy. We present data to guide future observational searches for new interstellar species, contributing to the ongoing exploration of complex organic molecules in space and their potential role in prebiotic chemistry.

The study entitled “Profitability and Resource Use Efficiency of Maize Production in Udayapur District, Nepal” analyzes the profitability and resource utilization efficiency of maize production in the region. Conducted in May 2023, it surveyed 80 farm households from Triyuga, Belaka, Katari, and Chaudhandigadhi municipalities. Data collection involved semi-structured questionnaires, Focus Group Discussions (FGD), and Key Informant Interviews (KII), using a clustered sampling technique. MS Excel and SPSS were used for analysis, with results presented through frequencies, percentages, and averages. Findings reveal that 77.5 percent of respondents primarily engage in agriculture. On average, 12.3 kattha of land is allocated to maize cultivation, yielding a net profit of 1780.0735 per kattha and a B/C ratio of 1.21. Costs of seed, fertilizer, and machinery significantly impact maize productivity at varying levels, with seed being the most influential factor. The study indicates a decreasing return to scale (0.881), suggesting inefficiency in resource allocation, particularly in labor. Efficiency ratios below 1 highlight excessive labor allocation, while resources like seed, machinery, and fertilizer are underutilized. To optimize resource allocation, reducing labor expenses by 74 percent while increasing expenditures on seed, fertilizer, and machinery by 98, 36, and 532 percent respectively is recommended. The prevalent practice of maize cultivation for self-consumption poses challenges in quantifying expenses, investments, and profits. Addressing these issues would contribute to enhancing the rural economy.

The research was conducted from February to June 2023 to assess the economics of the production and marketing of Tomatoes in Kaski. Pre-interview schedules, Focal Group Discussion (FGD), and Key Informant Survey (KIS) were used to collect the primary information from the respondents, while the secondary information was collected by reviewing different relevant publications. Altogether 61 respondents were selected using simple random sampling for the study from the Pokhara Metropolitan City within two different wards namely Bagmara and Budibazar. The statistical tools, MS- Excel and SPSS were used for data analysis. Socio-demographic studies revealed that the average number of male family members involved in agriculture was found to be 1.41 and that of female family members was 1.67. The average landholding of the farmers was 4.9 ropani and the average area under tomato cultivation under plastic houses was 1.6 ropani. Agriculture was the major occupation among the surveyed households. Srijana and Kabita were the popular varieties of tomato among the farmers of the study area and among them, Srijana was most preferred. The average productivity of tomato was found to be 42617 kg/ha and the average revenue of production of tomato was found to be NRs.2684871. Similarly, the gross margin and B: C ratio were found to be NRs. 1237656/ha and 1.38 respectively. Among 4 marketing channels identified in the area, Producer-Consumer was the most dominant with 59% of the total volume marketed. The major production and marketing problems were a lack of technical knowledge and a lack of storage facilities in the study area. However, the study indicated that tomato farming is a highly potential agriculture enterprise for the study area. Hence, it can be concluded from the study that commercial off-season tomato cultivation under plastic houses might be the potential enterprise to improve the living standard of the farmers.
Exploring investment requirements for energy efficiency upgrades in the private rental sector

Published: February 2025

Improving the energy efficiency of the residential housing sector represents a key challenge in meeting Ireland’s carbon reduction targets. While challenges exist across the sector in terms of incentivising upgrades, these difficulties are more pronounced in the rental sector, which suffers from the longstanding split incentive issue between landlords and tenants. Split incentive refers to the situation whereby landlords face the investment cost while tenants receive the benefit in terms of energy efficiency. However, to inform any policy response, it is important to quantify the scale of the investment requirements and to consider the profile of landlords and their financial capacity to make the required upgrades.

In this report, our research objectives are three-fold. First, we use a range of micro datasets to explore the energy-efficiency profile of the housing stock in the residential private rental sector (PRS). We draw on the Residential Tenancies Board (RTB) annual registrations data and the Sustainable Energy Authority of Ireland (SEAI) building energy rating (BER) research dataset. Second, we use unique micro data on investments on social housing upgrades and SEAI grants to cost the scale of upgrading the stock using a range of scenarios. Third, we focus on household landlords in Ireland, and explore their ability to finance investments in energy efficiency in rented dwellings using micro data from the Central Statistics Office’s (CSO) Household Finance and Consumption Survey (HFCS).
