Published: June 2023

Epiphytes are a group of non-parasitic plants that settle to obtain support from plants. Under the natural forest ecosystem, the presence of epiphytes is an indicator of unpolluted and undisturbed environment. However, massive infestation by epiphytes to commercial tree crops including tea is a concern to productivity. A study was conducted initiated to determine the influence of different management options on epiphytes which included mosses, ferns, maidenhair ferns, and tongue ferns. The study evaluated the influence of different management options on epiphytes and to determine the effect of the management options on tea yields. The experiment was laid on a field infested with epiphytes in split plot design treatment structure in a randomized complete block layout, replicated three times. In the main plots the epiphytes were manually removed from the tea bush branches whereas the control was left in situ while the subplots involved use of agricultural chemicals; Copper Nordox, Cuprocaffaro, Milraz, Hydrate of lime, Round up Turbo and control (untreated). Post-treatment scoring for 3 years of all types of epiphytes was done using a scale to determine the level of yellowing, scorching, and regrowth. Yield data were also recorded for one prune cycle of four years and data was subjected to analysis of variance. The main treatments (disturbed and undisturbed) management options did not influence the efficacy of the chemical products on epiphytic mosses but disturbance reduced (p less than or equal to0.05) levels of the epiphytic ferns. Copperbased products (Copper Nordox and Cuprocaffaro) reduced (p less than or equal to0.05) in mosses levels (reducing the degree of yellowing and regrowth) than other products and the control. However, all chemical products reduced (p less than or equal to 0.05) levels of epiphytic ferns. The removal of epiphytes on the tea branches increased (p less than or equal to0.05) the yield of tea, while chemical products were ineffective in improving yields. This study, therefore, concludes that the epiphytes on the tea frame have effects on the functioning of the tea bush and removal of the massive epiphytes is necessary for improved productivity of tea bush.

Published: June 2023

Tea is an important cash crop, providing income and employment to rural populations in many countries. In Kenya, tea is the leading export commodity crop and is grown in highlands east and west of the Rift Valley at altitudes ranging from 1300 to 2700 m above mean sea level. This has significant effects on growth, productivity, tea quality and response to fertilizer and has been particularly noted for the popular, widely planted, quality clone TRFK 6/8. In East Africa, tea husbandry practices are uniform despite the variations in responses to agronomic inputs. Fertilizer is the most expensive input in tea production after plucking. In tea, nitrogen availability is the most limiting crop growth factor. However, responses of tea yields to fertilizer application vary with the region of production even with the same cultivar. The utilization of nitrogen, therefore, varies with location. The responses in growth and yield parameters of clonal tea TRFK 6/8 and their contribution to yields were investigated across different environments, in a trial setup in three locations in the east of the Rift Valley in Kenya, using clone TRFK 6/8, a popular commercial cultivar. Yield and yield components response to nitrogen rates varied with location. The highest yields were not always attained at the highest nitrogen levels and the best response to fertilizer did not translate to the highest yields. Tea crop response to fertilizer is the site-specific and universal application of fertilizer may only apply as a general guideline but will not optimize production.

Tea sector contributes approximately 30% of export earnings in Kenya. Despite the industry continuing to realize positive gross margins, high costs of production coupled with weak trends in export prices threaten its future contributions. Nitrogen fertiliser is mandatory in tea production and its appropriate use promotes tea growth rate and yields. Previous studies using different tea cultivars established that optimal fertiliser rates varied with clones and geographical area of production. However, economics of nitrogenous fertilisers use on same tea cultivar in different tea growing regions in Kenya remains undefined. This study evaluated response of NPKS 25:5:5:5 fertiliser applied at 0, 75, 150, 225 and 300 kg N/ha/year on clone BBK35 to determine the viable economic rate under uniform management in different locations (Karirana, Timbilil, Changoi, Sotik Highlands and Kipkebe) within Kenya. The study used time series tea yield data and corresponding variable costs from field experiments running from 1997 to 2007. The data were subjected to Partial Budget Analysis (PBA) procedures for economic analysis of on-farm experiments. The economic returns varied with rate of nitrogen and region of production. Maximum marginal rate of return (MRR) were achieved at 75 kg N/ha/year at Kipkebe, Changoi and Timbilil, and 150 at Sotik Highlands and Karirana. However best economic returns were recorded at 300 kg N/ha/year in Kipkebe and Sotik Highlands, 225 kg N/ha/year in Changoi, and at 150 kg N/ha/year in Timbilil and Karirana. These results demonstrate that current uniform fertiliser recommendation rate of 100 to 220 kg N/ha/year may not be suitable for all regions. There is need to develop region specific nitrogen fertiliser requirements for tea growing areas in Kenya.

Published: June 2023

India is the world's second largest producer of black tea. Insects, mites, nematodes, and plant pathogenic diseases all damage the tea plant which severely hampered tea production causing about 10-15% crop loss every year. It would be 100% in extreme circumstances. In India, many synthetic pesticides are commonly employed to control tea pests. The use of an excessive amount pesticides could lead to a number of issues, including the development of resistance, negative impacts on non-target species such as insect predators and parasitoids, disruption of the ecological balance, and the accumulation of pesticide residues on tea leaves. In the international market, there is an increasing demand for organic tea or tea that is pesticide residue free, which influences the export price. Plant extracts having insecticidal qualities contains secondary metabolites such as alkaloids, terpenoids, phenolics, and minor secondary compounds can be used as an alternative to synthetic insecticides and these are environmentally safe, selective, biodegradable, cost-effective, and renewable options for use in IPM programmes in this context. Biopesticides are natural plant products that can be grown at a minimal cost by planters and extracted using indigenous methods.

Published: June 2023

Background: Coconut water is one of the natural food products that is widely available around the world. This commodity provides nutritional content that could increase rehydration status and improve health. The application of coconut water to health, including improving type 2 diabetes metabolism, has gotten research interest in recent years.
Objectives: This narrative review paper aimed to summarize several articles about the nutritional content and the mechanism of the potential bioactive component in coconut water to improve type 2 diabetes metabolism.
Methods: This study design was a narrative review of several articles from five databases search: PubMed/MEDLINE, Scielo, PsycINFO, Microsoft Academic, and Google Scholar.
Discussion: Coconut water includes several biologically active components such as protein, amino acid, fatty acid, mineral, vitamin, and phenolic compounds. The recent discovery of nutrient content, especially antioxidant properties, and arginine in coconut water, signifies a good potential in improving type 2 diabetes mellitus. Antioxidant and arginine altered blood glucose, glycated hemoglobin, serum creatinine, blood urea, albumin, albumin/globulin ratio, liver function enzyme, lipid profile, antioxidant status, and lipid peroxidation without any significant hepatocellular damage. Arginine enhanced the nitric oxide synthase activity in the liver and arginine levels in the plasma. In mammals, the arginine-nitric oxide system, which includes AMPK, cGMP, PGC-1α, and PI3K, can maintain blood glucose homeostasis, increase insulin sensitivity, and prevent diabetes-induced oxidative stress.
Conclusion: Coconut water can help to improve metabolism in type 2 diabetes mellitus conditions through antioxidant activity and arginine content.

Authors: Dela Cruz Ramiro Z. , Hernandez Gloria D.
Published: June 2023

At the onset of the Covid-19 pandemic, educational institutions worldwide needed to continue with their educational mandates for their learners, albeit not in the usual face-to-face modes. The Higher Education Institutions (HEIs) in the Philippines as well had to replace the on-campus teaching-learning modes with several variants of remote teaching. However, the various remote means are something quite new to both educators and learners, especially in mathematics, wherein various onboard instructions and on-desk hands-on exercises had been the norm. This study used of quantitative approach through online surveys to identify the educators’ challenges with remote teaching implementations in public schools in the Philippines. The findings reveal challenges related to the actual delivery of mathematics instruction, distractions from non-teaching tasks, curricular adjustments, alignment of materials, and orientation of parents or guardians and teachers. The pandemic may not be the last to impact the education system. Overall, the study shows an increased level of challenges for mathematics teaching. Thus, there is an urgent need to readjust policies and procedures affecting environmental learning conditions such as distractions, family-work-life balance, communication technology, rationalization of non-academic duties, increased participation, and support of parents and guardians.

Resistance in Murals: Critical Discourse Analysis of the Local Movement in Rejecting the Establishment of a Cement Factory in Rembang
Authors: Rahma Agustin Sarah
Published: June 2023

This research examines the discourse on rejecting the establishment of the Semen Indonesia factory in Rembang. Taking the murals in Tegaldowo Village, Rembang, as the object study, this study discussed the production of knowledge about the rejection of the factory establishment and power relations in such conflict over the factory establishment. This study applies a visual discourse analysis model developed by Gillian Rose, which includes several essential elements in the text: key themes, justification strategies and their effects, contradictions, positions of the subjects, and location and time of production. This research finds that the movement against the establishment of a cement factory, in addition to going through legal channels, was carried out through cultural media, including by forming discourses that strengthened this rejection. The justification for refusing the establishment is generally based on both traditional and modern ecological discourses. The subjects presented in the text represent the polarization of interests and groups within the local communities, between groups that are pro and contra to the construction of the cement factory, as well as justifying that the cement factory establishment causes such polarization.

Published: June 2023

Objective: This study was aimed at analyzing the efficacy and safety of an injectable form of chlorogenic acid (CGA) in patients with recurrent high-grade glioma after standard of care treatments, through a first-in-human, open-label, dose-escalation phase I trial. Methods: A total of 26 eligible patients were enrolled, received intramuscular CGA injections at 5 dose levels, and were followed up for 5 years. CGA was well tolerated, and the maximum tolerated dose was 5.5 mg/kg. Results: The most common treatment-related adverse events occurred at the sites of injection. No grade 3 or 4 adverse events (e.g., drug allergy) were reported for these patients except for induration at the injection sites. A clinical pharmacokinetic study showed that CGA was rapidly eliminated from the plasma, with a t1/2 of 0.95–1.27 h on day 1 and 1.19–1.39 h on day 30, and no detectable CGA was observed on days 9, 11, 13, 23, 25, 27, and 29 before CGA administration. After the first treatment cycle, 52.2% of patients (12 of 23) achieved stable disease. Long-term follow-up indicated an estimated median overall survival of 11.3 months for all 23 evaluable patients. Of the 18 patients with grade 3 glioma, the median overall survival was 9.5 months. Two patients remained alive at the cutoff day. Conclusions: This phase I study demonstrated that CGA has a favorable safety profile (with no severe toxicity), and provides preliminary clinical benefits for patients with high grade glioma relapsing after prior standard therapies, thus shedding light on the potential clinical application of CGA for recurrent grade 4 glioma.

Authors: Suheera Mohamed Yaseen Minnathul , Wazeema Thaseem Mohamed Fathima
Published: June 2023

The economic crisis in early 2022 in Sri Lanka has had a massive negative impact on the social and economic life of female-headed households in the country. In particular, food poverty affects many families. This study was conducted to investigate the food consumption patterns of female-headed households after the economic crisis in Sri Lanka. Female headed households in five Divisional Secretariat Division of Ampara District were selected as the study sample based on purposive sampling techniques. Qualitative research methodology was used. In-depth interview and focused group discussion were used as primary data collection tools. The collected data were analyzed using thematic analysis method. The study found that after the economic crisis in Sri Lanka, there was a massive decline in food consumption, quality of food consumed and quantity of food consumed by female-headed households. Most female-headed households consume food only to satisfy hunger. Very small households have maintained the quality of food consumption, which has put them in debt. Traditional food consumption practices have changed and new food habits have emerged in certain families. The study suggests that the prevalence of food poverty among female-headed households should be addressed immediately and alternative programs should be designed to improve their condition.

Authors: Sakib S M Nazmuz
Published: June 2023

The sociology of culture is an important field that examines how societies create, maintain, and transform their cultural practices and beliefs. In the context of Bangladesh and India, this field is particularly relevant due to their rich and diverse cultural heritage. This paper explores the sociology of culture in these countries, focusing on cultural similarities and differences. Through a literature review of research from anthropology, sociology, history, and related fields, we will examine the historical background of cultural development in both countries, considering the impact of colonialism, nationalism, globalization, language, ethnicity, and religion. We will then present a comparative analysis of cultural practices, beliefs, and values, drawing on empirical data and case studies. This paper aims to contribute to our understanding of the sociology of culture in Bangladesh and India by shedding light on their diverse cultural heritage and exploring the ways in which cultural practices and values are shaped by historical, social, and political factors. By comparing the cultural similarities and differences between these nations, we hope to deepen our understanding of how culture is influenced by the broader social and political context.
Exploring inequity factors in higher education: Promoting equitable access and success in the US
Authors: Adoui Aicha
Published: June 2023

The issue of equity in higher education has gained prominence as it has become increasingly clear that opportunities for higher education are not equitably distributed among different student groups. This paper provides a thorough understanding of the key components of equitable access and success in higher education, primarily in the context of the United States. It also seeks to explore the effectiveness of affirmative action, financial aid and scholarship systems, successful initiatives, cultural and sociological attitudes, and institutional structures and services in promoting equitable access and success in higher education. The paper uses a systematic review methodology to analyze academic and policy documents, program evaluations, and case studies. The analysis includes a synthesis of key findings and themes from the literature review, an examination of successful initiatives and programs in higher education institutions in the United States. The findings suggest that while affirmative action and financial aid programs have been successful in promoting equitable access and success in higher education, further efforts are needed to address cultural and societal attitudes that perpetuate inequities in higher education. Recommendations for future research include the long-term effects of financial aid and cultural barriers to building a more equitable education.
Empirical Correlations for Predicting Flow Rates Using Distributed Acoustic Sensor Measurements, Validated with Wellbore and Flow Loop Data Sets
Authors: Tabjula Jagadeeshwar , Shetty Rishikesh , Adeyemi Temitayo , Sharma Jyotsna
Published: June 2023

Distributed acoustic sensing (DAS) is an emerging surveillance technology that is becoming increasingly popular in the oil and gas industry for real-time flow monitoring. However, there are limited studies that rigorously quantify flow rates using DAS. This work expands the existing literature by presenting a detailed workflow for accurately estimating fluid flow rates from DAS data using time- and frequency-domain signal processing. Three simple empirical correlation functions (linear, exponential, and cubic) are developed and tested to predict flow rates from DAS. The proposed correlations are demonstrated for flow rates ranging from 50 to 300 gallons per minute (GPM) in a vertical 5,163-ft-deep wellbore and from 12 to 36 GPM in a horizontal surface flow loop. Tests were performed using a single-phase flow of water as well as using synthetic oil-based drilling mud. Time-domain DAS processing using root-mean-square (RMS) value and frequency-domain processing using frequency band energy (FBE) is evaluated, followed by a statistical approach to minimize the influence of outliers. The RMS and FBE approaches are individually compared for flow prediction, and the performance of the correlations is rigorously evaluated on a blind data set that was not originally used for developing the correlations. For both the wellbore and flow loop data sets, a coefficient of determination (or R2) greater than 0.95 with an average flow rate prediction error of less than 10% was achieved for the best-performing correlation for the blind test data. The analysis procedure and workflow presented in this study can be adopted and extended to different operating conditions for quantitative flow rate prediction using DAS.
Examining the nexus between medical education and complexity: a systematic review to inform practice and research.
Authors: Ogden Kathryn , Kilpatrick Sue , Elmer Shandell
Published: June 2023

Background: Medical education is a multifarious endeavour integrating a range of pedagogies and philosophies. Complexity as a science or theory (‘complexity’) signals a move away from a reductionist paradigm to one which appreciates that interactions in multi-component systems, such as healthcare systems, can result in adaptive and emergent outcomes. This examination of the nexus between medical education and complexity theory aims to discover ways that complexity theory can inform medical education and medical education research.
Methods: A structured literature review was conducted to examine the nexus between medical education and complexity; 5 databases were searched using relevant terms. Papers were included if they engaged fully with complexity as a science or theory and were significantly focused on medical education. All types of papers were included, including conceptual papers (e.g. opinion and theoretical discussions), case studies, program evaluations and empirical research. A narrative and thematic synthesis was undertaken to create a deep understanding of the use of complexity in medical education.
Results: Eighty-three papers were included; the majority were conceptual papers. The context and theoretical underpinnings of complexity as a relevant theory for medical education were identified. Bibliographic and temporal observations were noted regarding the entry of complexity into medical education. Complexity was relied upon as a theoretical framework for empirical studies covering a variety of elements within medical education including: knowledge and learning theories; curricular, program and faculty development; program evaluation and medical education research; assessment and admissions; professionalism and leadership; and learning for systems, about systems and in systems. Discussion: There is a call for greater use of theory by medical educators. Complexity within medical education is established, although not widespread. Individualistic cultures of medicine and comfort with reductionist epistemologies challenges its introduction. However, complexity was found to be a useful theory across a range of areas by a limited number of authors and is increasingly used by medical educators and medical education researchers. This review has further conceptualized how complexity is being used to support medical education and medical education research. Conclusion: This literature review can assist in understanding how complexity can be useful in their own practice.

Authors: Cao Kai-hua , Li Sai , Liu Qi , Wang Jia-Wei , Wan Jing-hai
Published: June 2023

Glioma, a prevalent type of brain cancer, is associated with poor prognosis. The purpose of this study was to investigate the correlation between disulfidptosis-related lncRNAs (DRLncs) and survival outcomes of glioma patients. Transcriptome and clinical data for glioma patients were retrieved from The Cancer Genome Atlas (TCGA) database. Ten disulfidptosis-related genes (DRGs) were identified from literature. Co-expression analysis was performed to identify DRLncs associated with glioma. A risk prognostic model for DRLncs was constructed using COX regression analysis and LASSO regression analysis. The model was validated by dividing samples evenly into training and test groups and conducting various analyses including survival analysis, ROC curve analysis, independent prognostic analyses, and PCA. GO and KEGG enrichment analysis was also performed on differentially expressed genes between high-risk and low-risk groups. Variances in the immune microenvironment, immune cells, and immune-related functions were analyzed between high-risk and low-risk groups. Drug sensitivity analysis was conducted to identify potential therapeutic drugs for glioma treatment, and the TIDE database was used to evaluate the potential for immune escape. The expression of DRLncs in glioma was verified through real-time quantitative PCR. Through co-expression analysis, 136 disulfidptosis-related LncRNAs were identified. Univariate Cox analysis revealed that 86 of these LncRNAs significantly correlated with overall survival (OS) in glioma patients. Using the Lasso-Cox method, a model consisting of 7 LncRNAs was constructed and optimized. This model effectively differentiated between individuals at high risk and those at low risk, with good survival prediction ability. GO and KEGG analysis indicated that the differential gene enrichment in the high- and low-risk groups was related to immune-related functions. The study observed divergences in the immune microenvironment, immune cells, and immune-related functions between the high-risk and low-risk groups. Furthermore, immunotherapy response scoring indicated that patients in the low-risk group exhibited better response to immunotherapy. Finally, real-time quantitative PCR results showed that the expression of low-risk LncRNA (ZBTB20-AS4) was low in tumor tissue, while the expression of high-risk LncRNAs (POLR2J4, SUCLG2-AS1, and UBA6-AS1) was high in glioma tumor tissue. Overall, this study established a novel glioma prognosis model that explored disulfidptosis-related lncRNAs to guide glioma prognosis.

The goal of this research is to create a cloud identification model for short-term solar power generation forecasting using deep learning methods. Deep learning techniques such as U-net, HRnet, and Detectron2 were used to perform semantic and instance segmentation of clouds. Transfer learning was employed, with weights trained on the "2012 ILSVRC ImageNet" dataset and architecture configurations such as Resnet, Efficient, and Mask RCNN. As a validation metric, the models were trained using the Jaccard Coefficient. The best model, a U-net with Resnet18 at 486x648 resolution, achieved an average Intersection over Union (IoU) of 0.6, indicating good cloud segmentation performance. All models were affected by the data imbalance, with the tree class causing a favorable bias towards the overall results. The HRNet model demonstrated refined pixel-level segmentation but was ineffective at detecting dominant clouds. This research provides insights into effective cloud identification techniques and lays the groundwork for future cloud classification model development. The model may be able to predict cloud motion. For future works the team will investigate dataset balancing and data augmentation transformations for model improvement. The research demonstrates the effectiveness of deep learning in cloud identification for solar power forecasting.
Development of Energy Enterprises in the Context of Green Transformation

Published: June 2023

The article argues that the search for effective tools to ensure the economically secure future of energy companies and their development in the context of green transformation is necessary due to the speed of global transformations, the priority of reducing dependence on fuel and energy imports, the development of renewable energy sources, the instability of the environment for the functioning of energy companies (as a result of russia’s full-scale invasion of Ukraine) and their position both on the Ukrainian and European energy markets. The reality of the energy sector in the country and the steps for the recovery of the energy companies determined by the Economic Recovery Plan of Ukraine were analyzed. The evidence shows that the legislative amendments aimed at stabilizing the energy sector and solving key issues lack efficiency and cannot ensure the vital activity of energy enterprises and their development in the conditions of climate-neutral transformation. A methodology was proposed to assess the progress of the carbon-neutral development of energy companies, which should become the basis for attracting ESG investing. The vectors for creating a favorable environment for environmental, social, and governance (ESG) investing were identified as a unique opportunity to ensure the economically secure future of energy companies and their development in the context of green transformation.
Conversation Analytic Perspectives to Digital Interaction. Practices, Resources, and Affordances

Published: June 2023

This book offers a collection of state-of-the-art conversation analytic work on the impact of different types of digital technologies and media on social interaction. It furthers our understanding of whether and to what extent the varying practices of digital interaction can be considered adaptations of the basic organisations and resources of co-present face-to-face interaction. The chapters explore the emerging practices in contemporary digital interaction and in interaction related to digital technologies. The volume is organised into four sections according to the platform or type of digital interaction: mobile messaging, social media, video conferencing, and human-computer interaction. Each of the chapters highlights an interactional or linguistic phenomenon – an action, a practice, a sequence, or a larger structure. Some of these are unique to online environments, such as emojis or hashtags, whereas some occur in both online and offline interaction, such as repair initiators and proposal sequences.
Cavity induced collective behavior in the polaritonic ground state

Published: June 2023

Cavity quantum electrodynamics provides an ideal platform to engineer and control light-matter interactions with polariton quasiparticles. In this work, we investigate collective phenomena in a system of many particles in a harmonic trap coupled to a homogeneous cavity vacuum field. The system couples collectively to the cavity field, through its center of mass, and collective polariton states emerge. The cavity field mediates pairwise long-range interactions and enhances the effective mass of the particles. This leads to an enhancement of localization in the matter ground state density, which features a maximum when light and matter are on resonance, and demonstrates a Dicke-like, collective behavior with the particle number. The light-matter interaction also modifies the photonic properties of the polariton system, as the ground state is populated with bunched photons. In addition, it is shown that the diamagnetic A^2A2 term is necessary for the stability of the system, as otherwise the superradiant ground state instability occurs. We demonstrate that coherent transfer of polaritonic population is possible with an external magnetic field and by monitoring the Landau-Zener transition probability.
Sin stocks in European countries: The influence of wealth and familiarity bias on investment choices
Authors: Hamdan Mohammed , Fernandez Calavia Pedro , Aminu Nasir
Published: June 2023

This study examines the relationship between the wealth of European societies and their investment decisions in «sinful» industries, including tobacco, alcohol, and gambling. The study aims to challenge the widely held belief that wealthier countries are more socially responsible in their investment choices and to investigate the impact of familiarity bias on investment decisions in these industries. An experimental research design with panel data compares the returns from a portfolio of sin stocks from Northern Europe with a portfolio of sin stocks from Southern and Eastern Europe. The study utilises multiple models, including the CAPM single-factor, the Fama-French three-factor, and the Fama-French five-factor, to measure the risk-adjusted returns of sin stocks across various European countries. Findings reveal that sin stocks from wealthier countries tend to have higher risk-adjusted returns compared to those from less wealthy countries. Sin stocks have a significant relation with the market, but their volatility is consistently lower. Countries that drink more alcohol are more willing to invest in alcohol stocks than countries that drink less, as these stocks outperform the market during economic downturns. Sin stocks impact financial performance, investor behaviour, social responsibility, market efficiency, and regulations. The study uncovers the influence of familiarity bias, indicating that investors from countries more accustomed to «sinful» activities are less reluctant to invest in such industries than countries with lower familiarity. This finding highlights the importance of cultural and social factors in shaping investment decisions and challenges traditional concepts of market efficiency.
