Published: August 2024

African urban agriculture (UA) has garnered attention for its contributions to food security and socio-economic improvement. However, its impact on the psychological well-being of farmers has received minimal focus. This study explores the psychosocial effects of UA by surveying 733 farmers in Dar es Salaam and Greater Lomé. Utilizing the Mental Health Continuum–Short Form (MHC-SF) and bespoke questionnaires, our research evaluates the emotional benefits of urban farming. Findings from regression analyses and spatial assessments conducted using Python and QGIS 3.32.2-Lima indicate significant variations in UA-related happiness across different city zones, with peripheral farmers experiencing greater satisfaction than their urban counterparts. Notably, female farmers reported higher levels of happiness, underscoring UA’s potential to empower women. This study advocates for the integration of UA into urban planning frameworks to foster psychologically beneficial urban environments.

Authors: Li Cheng , Mao Xiaojie , Zheng Mingxing , Han Mingyang
Published: August 2024

An in-depth examination of the effects of climate change on rice yield in China, encompassing various rice types, is crucial for ensuring the nation’s food security. This study develops an “economy-climate” theoretical model and employs Panel Corrected Standard Error Estimation (PCSE) on panel data spanning from 1978 to 2018, sourced from China’s primary grain-producing regions. The analysis delves into the impact of climate variables, including precipitation, temperature, and sunshine duration, on overall rice production and different rice types. Overall, the findings reveal a nonlinear relationship between precipitation, temperature, sunshine duration, and rice yield, characterized by an “inverted U-shaped” pattern. However, significant variations exist in the effects on different rice types across China’s main grain-producing areas. Increasing precipitation generally enhances early rice production across provinces and also augments mid-season and one-season-late rice production in the Inner Mongolia Autonomous Region, Hebei, Jilin, Heilongjiang, and Shandong Province. Conversely, it reduces mid-season and one-season-late rice output in Liaoning, Jiangsu, Anhui, Jiangxi, Henan, Hubei, and Hunan. Sichuan Province sees a rise in temperature favoring early and double-season-late rice production, unlike other provinces. For mid-season and one-season-late rice, temperature increases benefit output in Heilongjiang Province but not in other regions. Additionally, prolonged sunshine duration boosts early and double-season-late rice production across all provinces but does not have the same effect on mid-season and one-season-late rice in China’s primary grain-producing areas.

Governing Lateral Load on Tall Buildings in Canadian Regions
Authors: Vasilopoulos Stephen , McTavish Kendra , Elshaer Ahmed
Published: August 2024

Urbanization has led to a significant increase in the construction of tall buildings in Canada. The design of tall buildings must ensure structural integrity in withstanding lateral loads, such as wind and earthquakes. The tendency for a specific lateral load to govern building design varies based on the building characteristics, building height, and location of the building. There is a need to identify the governing lateral load (i.e., wind or earthquake) for use in the preliminary design and city-scale assessment. This study examines the governing lateral loads for tall buildings across different Canadian regions through a parametric analysis of a typical high-rise building based on the Commonwealth Advisory Aeronautical Council (CAARC) building. This research evaluates varying building heights, structural systems, and geographic locations under the guidelines of the National Building Code of Canada (NBCC). The analysis identifies the dominant lateral load, providing insights into assessing the existing infrastructure and optimal design strategies for enhancing building sustainability and resilience. Our findings highlight the critical role of geographic location in determining lateral load impacts and the necessity of context-specific design to promote long-term structural performance and environmental sustainability.
Rethinking External Environmental Analysis for Sustainable Development: The Case of a Beverage Manufacturing Industry in a Southern African Country
Authors: Ruwanika Eliot Quinz Farai , Massyn Liezel
Published: August 2024

The advent of the United Nations Sustainable Development Goals (SDGs) Agenda 2030 ushered in a new way of thinking about the forces that drive change in the business environment. Literature suggests that sustainable development is a megaforce driving change globally and envelops the traditional political, economic, social, technological, and ecological (PESTE) forces approach. This article reframes the external environmental analysis to integrate SDGs into the business strategy of a beverage manufacturing industry. A qualitative design using snowball sampling resulted in semi-structured, face-to-face interviews that were audio recorded. Interviews were held with eight executives, one former executive, and three non-executive staff from four companies of a southern African country’s beverage manufacturing industry. The data exposed some ignorance on sustainable development. Many executives understood the importance of sustainable development without consensus on its exact nature and implementation in the organisational context. Thematic data analysis confirmed the relevance of sustainable development and the need to incorporate it in external environmental analysis. Categorising SDGs into a 5-P framework (people, prosperity, planet, peace, partnerships) and integrating it with the PESTE framework, the study provides a new approach/tool for external environmental analysis. This approach facilitates identification of SDGs that are relevant to business during strategic planning.

The methodology used in this work is based on several steps of systematic literature mapping, which seeks to provide a comprehensive overview of the literature on this topic, classify the findings, and offer a framework for future research in this area. The main findings highlight the need for organizational policies and work practices that promote gender equality, as well as the importance of early education and training in retaining female talent in the software industry. This study not only contributes to academic discourse but also suggests practical measures for industry professionals to foster a more inclusive and equitable work environment.
A New Generalization of the Inverse Generalized Weibull Distribution with Different Methods of Estimation and Applications in Medicine and Engineering
Authors: Alsaggaf Ibtesam A. , Aloufi Sara F. , Baharith Lamya A.
Published: August 2024

Limitations inherent to existing statistical distributions in capturing the complexities of real-world data often necessitate the development of novel models. This paper introduces the new exponential generalized inverse generalized Weibull (NEGIGW) distribution. The NEGIGW distribution boasts significant flexibility with symmetrical and asymmetrical shapes, allowing its hazard rate function to be adapted to many failure patterns observed in various fields such as medicine, biology, and engineering. Some statistical properties of the NEGIGW distribution, such as moments, quantile function, and Renyi entropy, are studied. Three methods are used for parameter estimation, including maximum likelihood, maximum product of spacing, and percentile methods. The performance of the estimation methods is evaluated via Monte Carlo simulations. The NEGIGW distribution excels in its ability to fit real-world data accurately. Five medical and engineering datasets are applied to demonstrate the superior fit of NEGIGW distribution compared to competing models. This compelling evidence suggests that the NEGIGW distribution is promising for lifetime data analysis and reliability assessments across different disciplines.

Published: August 2024

The first case of COVID-19 was detected in Bangladesh on 8 March 2020. Since then, the Government of Bangladesh (GoB) has implemented various measures to limit the transmission of COVID-19, including widespread testing facilities across the nation through a laboratory network for COVID-19 molecular testing. This study aimed to analyze the dynamics of SARS-CoV-2 in Bangladesh by conducting COVID-19 testing and genomic surveillance of the virus variants throughout the pandemic. Nasopharyngeal swabs were collected from authorized GoB collection centers between April 2020 and June 2023. The viral RNA was extracted and subjected to real-time PCR analysis in icddr,b’s Virology laboratory. A subset of positive samples underwent whole-genome sequencing to track the evolutionary footprint of SARS-CoV-2 variants. We tested 149,270 suspected COVID-19 cases from Dhaka (n = 81,782) and other districts (n = 67,488). Of these, 63% were male. The highest positivity rate, 27%, was found in the >60 years age group, followed by 26%, 51–60 years, 25% in 41–50 years, and the lowest, 9% in under five children. Notably, the sequencing of 2742 SARS-CoV-2 genomes displayed a pattern of globally circulating variants, Alpha, Beta, Delta, and Omicron, successively replacing each other over time and causing peaks of COVID-19 infection. Regarding the risk of SARS-CoV-2 infection, it was observed that the positivity rate increased with age compared to the under-5 age group in 2020 and 2021. However, these trends did not remain consistent in 2022, where older age groups, particularly those over 60, had a lower positivity rate compared to other age groups due to vaccination. The study findings generated data on the real-time circulation of different SARS-CoV-2 variants and the upsurge of COVID-19 cases in Bangladesh, which impacted identifying hotspots and restricting the virus from further transmission. Even though there is currently a low circulation of SARS-CoV-2 in Bangladesh, similar approaches of genomic surveillance remain essential for monitoring the emergence of new SARS-CoV-2 variants or other potential pathogens that could lead to future pandemics.
Proliferating Cell Nuclear Antigen in the Era of Oncolytic Virotherapy
Authors: Kwan Amy , Mcdermott-Brown India , Muthana Munitta
Published: August 2024

Proliferating cell nuclear antigen (PCNA) is a well-documented accessory protein of DNA repair and replication. It belongs to the sliding clamp family of proteins that encircle DNA and acts as a mobile docking platform for interacting proteins to mount and perform their metabolic tasks. PCNA presence is ubiquitous to all cells, and when located in the nucleus it plays a role in DNA replication and repair, cell cycle control and apoptosis in proliferating cells. It also plays a crucial role in the infectivity of some viruses, such as herpes simplex viruses (HSVs). However, more recently it has been found in the cytoplasm of immune cells such as neutrophils and macrophages where it has been shown to be involved in the development of a pro-inflammatory state. PCNA is also expressed on the surface of certain cancer cells and can play a role in preventing immune cells from killing tumours, as well as being associated with cancer virulence. Given the growing interest in oncolytic viruses (OVs) as a novel cancer therapeutic, this review considers the role of PCNA in healthy, cancerous, and immune cells to gain an understanding of how PCNA targeted therapy and oncolytic virotherapy may interact in the future.

This study investigated the distribution of sedimentary phosphorus (P) species along an area of a rapid current at the southern coast of Zhoushan Island. The objective of this study was to improve the understanding of P cycling in a zone of rapid water cycling. Results showed that the average percentage of each P form to total P (TP) was in the following order: apatite P (Ca-P; 52%) was found in the most abundant, followed by organic P (OP; 16%), exchangeable-P (Ex-P; 14%), detrital P (De-P; 11%), and iron-bound P (Fe-P; 7%). Ca-P showed a trend of an increasing concentration from a location at the west (ZS1 has mean Ca-P = 45.6 mg kg−1) toward the east (ZS2 has mean Ca-P = 82.69 mg kg−1) and south-east (ZS3 has mean Ca-P = 82.17 mg kg−1); De-P also increased from 15.12 mg kg−1 at ZS1 to 22.53 mg kg−1 at ZS2 and 27.45 mg kg−1 at ZS3, but the three bioavailable P species, OP, Ex-P, and Fe-P, decreased from the west toward the east of the coastal area. Results along the cores showed the occurrences of sediment P adsorption and release throughout the time span from the 1930s to the present, with an overall trend of decreasing Ca-P and TP from the bottom to surface sediments. There was a tendency of Ca-P formation at the expense of Ex-P and OP release during transport and organic matter decomposition. The likely impact of climate change in the coastal zone would be an increased temperature resulting in elevated organic matter decomposition and P release.

Socioeconomic Repercussions of Biohazard on Geoscientific Activities with Regression Analysis for Oil Demand: Impact of Pandemic Covid-19
Authors: Jamil Muhammad , Usman Muhammad , Ahmed Nisar
Published: August 2024

The epidemic of coronavirus has a long term impact on the interests of geosciences, and has important consequences for the socio-economic front. This paper aims to discuss the alterations in academic and industry operations of geoscience because of this pandemic spread and its ramifications on global oil demand and its socio-economic consequences. The coronavirus outbreak could be the most defining event for the socio-economic incident of this decade. It has profound implications on industry, community, corporations, environment, and governments. Coronavirus is a type of biohazard that has adversely affected all the fields of science including geosciences. The teaching, research, training, and lab activities are suspended or replaced with online methodologies. International geoscience conferences, seminars, student education weeks, and geological fieldwork are delayed or postponed. In the oil, mining, and geotechnical industries, more than 90% of field operations are delayed to remain safe from a pandemic disease. Oil price slash to more than 20% in a single day, the lowest in three decades. Low demand for some mining and mineral goods also reduces their market prices to about 10% or more. Geotechnical projects related to the establishment of emergency health units were done at a rapid pace while other infrastructure projects were put on a halt to decrease the human impact and mitigate the extension of the epidemic. The socio-economic implications are discussed with the oil market, traveling and aviation, and services and industry sector. Oil market contracts owing to less industry production that hindered the business and economy. In comparison, the p-value of the oil market is below 0.05, and this analysis shows a negative regression coefficient. Owing to lower economic operation and reduced demand, manufacturing and services have also been affected. All these sectors consequently resulted in the huge number of employee layoffs, work at home trend, delaying in construction and infrastructure projects, and reduced social interaction. However, this pandemic encourages us to pursue more creative approaches of virtual and online platforms for academic and industry activities by inculcating the artificial intelligence and advanced technological solutions.

Published: August 2024

Introduction: Online learning is an accessible method that enables medical practitioners to undertake training to develop new, and reinforce existing, knowledge and skills. Early career medical practitioners may find engaging in online learning particularly beneficial as they have a stronger motivation to refine knowledge and skills than their more senior peers. One under-explored mechanism to strengthen the delivery of online learning for medical practitioners is the use of clinical data to tailor learning so it is closely aligned with the individual health professional’s clinical practice.
Methodology: This study aimed to evaluate the feasibility of personalising an online learning program for early career doctors working in oncology using electronic medical record (EMR) data. An online program was developed by clinical domain experts that could be triggered using pathology orders and/or results closely aligned to when the test was ordered in clinical practice. The program content was designed to cover three categories: (1) test ordering, (2) interpreting test results, and (3) patient management. Early career medical practitioners undergoing oncology training were recruited to participate in the study. The program was evaluated using metrics captured by the online learning platform, and a post-program survey.
Results: All early career medical practitioners eligible to participate in the study consented to participate (n=5). It was feasible to personalise the online program using pathology ordering data. Further, analysis of survey responses indicated that personalising an online learning program using EMR data was acceptable to early career doctors and facilitated engagement with the course.
Conclusion: Personalising an online learning program for early career medical practitioners in cancer care using electronic health-record data is both feasible and acceptable.

The sunflower oil is pressed from the seeds of the sunflower plant (Helianthus annuus). It contains high amounts of the essential fatty acid, linoleic acid. Sunflower oil is commonly consumed in foods. The quality of sunflower oil depends on the quality of the sunflower seeds to be processed, the storage conditions of the seeds before pressing and the refining conditions. The standard chemical methods used to determine the chemical content of the oils are usually time-consuming,labor-intensive and expensive. Therefore, we have tested four physical methods measuring refractive indices and their dispersion curves, color parameters, UV-VIS spectroscopic and fluorescence spectra that are related to the chemical structure and composition of the sunflower oils. The refractive indices of the samples were measured using a laser refractometer at wavelengths of 405 nm, 447 nm, 532 nm and 656 nm. The dispersion curves and the dispersion parameters were approximated using one-term Sellmeier model. The color parameters were obtained using a Lovibond PFX 880 spectrophotometer. The values for the refractive indices were compared to these, obtained by a standard method using the Abbe refractometer. These methods are fast, easy to perform and do not require any additional chemical agents. Four groups of sunflower oils – cold pressed, oil with added antioxidants and commercially refined and nonrefined sunflower oil, were investigated.

Citral is an acyclic monoterpene aldehyde that occurs in natural products in two forms: -form (trans-3,7-dimethyl2,6-octadiene-1-al) and -form (cis-3,7-dimethyl-2,7-octadiene-1-al). The trans-form is also called geranial (citral a) and the cis-form neral (citral b). This aromatic substance is found in many essential oils - eucalyptus, lemongrass, citronella, lyceum, lemon wormwood, verbena, etc. It is mainly isolated from eucalyptus, lychee, lemongrass and other essential oils. For industrial purposes, however, it is synthesized. It has poor resistance to light, air and heat. Technical citral is more stable in soaps. It is used in perfumery and cosmetics, to flavor various food products and it is also used as a raw material for the synthesis of many other aromatic substances. The aim of the present study is to predict the biological effects of citral by applying an in silico approach.

Темой исследований являются крестьянские лодки, которые бытовали и бытуют на внутренних водных путях и бассейнах озер России. Под народным лодкостроением предлагается понимать изготовление и использование в личном крестьянском хозяйстве различных типов местных лодок. Народные лодки все еще мало изучены, что связано с отсутствием разработанной исследовательской методики, единых подходов к сбору информации, обмерам и описанию лодок. Во многих локальных центрах еще есть мастера, сохраняющие местные традиции лодкостроения, историю их возникновения и развития, что подтверждают материалы полевых исследований автора, находки документов и фотографий. В данной статье автор предлагает методику исследований лодок, апробированную в 25 экспедициях.
