Plants have sustained the life of man since the beginning of the time. Their functionalities go beyond being wood for fire, instead, they are able to protect, provide and nourish. The many purposes of plants have been described by many. In this article, we will describe functional plants through the chemical perspective particularly the biologically active secondary metabolites. The initiatives in natural products studies can be traced to the early years of man when plants were used for health and treatment management as documented in traditional materia medica. In modern days, numerous phytochemicals have become the main ingredients in drugs, foods, cosmetics and many more after detailed and rigorous research programs which determine their safety and efficacy. In Malaysia, and Sabah in particular, efforts are planned and carried out to identify potential traditional plants that will be beneficial in their truest forms.
MALAYSIAN ESL STUDENTS’ ATTITUDE, PERCEPTIONS AND PREFERENCES OF TEACHER WRITTEN FEEDBACK IN WRITING
Authors:   Academy of Language Studies, Universiti Teknologi MARA Sabah Branch, Kota Kinabalu Campus, RAHMAN WONG SUZIE
Published: April 2024

Students’ perception and preferences on teacher-written feedback (TWF) tend to vary in different learning contexts. This study explores the perceptions and preferences of TWF among 78 Malaysian ESL students in a public pre-university college in Malaysia. Quantitative data were obtained from a questionnaire to examine the students’ general attitude and perceptions of TWF, and their preferences of the types and amount of written feedback received on their written work. This study reveals that the ESL students had a positive attitude and perception of the teacher-written feedback practice based on the perceived usefulness of the feedback, and the integrative-feedback type that combines both the content and language feedback was mostly favoured. The result also shows that the students had a high preference for indirect coded corrective feedback strategy in highlighting language errors, and preferred a large amount of feedback that highlighted all errors on their written work. These findings potentially help teachers to make a more informed decision when using teacher-written feedback so as to cater to students’ varying needs and perceptions in order to improve its use in writing.
Free fatty acid-rich oils as potential benign organic solvent for dyes removal in solvent extraction system
Authors: Abdul Halim Siti Fatimah , Yusuf Siti Aishah , Chang Siu Hua , Amri Nurulhuda
Published: April 2024

The extensive use of water in the textile industry results in the production of significant volumes of effluent-containing dyes, posing both economic and environmental concerns due to their harmful impact. Hence, the removal of dye from wastewater is very important for environmental protection and other aspects of well-being. Solvent extraction emerges as one of the promising methods used for dye removal. Nevertheless, the conventional organic phase formulation comprises an extractant, diluent, and modifier sourced from petroleum-based compounds, leading to environmental degradation. Thus, in this study, free fatty acid (FFA)-rich oils, i.e., Palm Kernel Fatty Acid Distillate (PKFAD) and Jatropha Oil (JO), were proposed as the green and benign organic solvent for the extraction of Crystal Violet-(CV) and Methylene Blue-(MB) from an aqueous solution. These FFA-rich oils act as reactive diluents due to the presence of FFA, which acts as an acidic extractant. Therefore, a new formulation of green sole-organic solvent without the addition of extractant and modifier was applied in this system. This study aimed to determine the best pH equilibrium for extracting CV and MB from different FFA-rich oils, i.e., PKFAD and JO. The results indicated the optimum extraction of CV is 95% at an equilibrium pH of 2.7 and 6.3 for PKFAD and JO, respectively. In comparison, the extraction of MB achieved 88% (pH 5.5) and 86% (pH 8.5) for PKFAD and JO, respectively. The stripping obtained a high removal percentage for both CV and MB, with 93% and 99%, respectively.

Published: April 2024

An experiment was carried out to investigate the effect of different organic nutrient solutions and day of harvest on growth parameters, biomass and chemical composition of hydroponically grown sorghum red fodder. The experiment was a 3 × 2 factorial design comprising of 3 nutrient solutions (cattle, poultry and rabbit) and 2 harvesting regimes (8th and 10th day). Cattle, poultry and rabbit dungs were collected fresh and processed into nutrient solutions. Sorghum red seeds were treated, planted on trays, and irrigated twice per day with organic nutrient solution according to the treatments. Growth parameters which were investigated included fodder mat thickness, seedling height, leaf length and width, number of leaves, fresh and dry matter yield; and proximate composition. The results showed that sorghum red fodder irrigated with cattle manure nutrient solution (NS) harvested at 10 days was higher in all, except one (fodder mat thickness) of the growth parameters considered. The crude protein (CP) was highest and similar (P > 0.05) for Poultry NS harvested at 8 and 10 days, and Cattle NS at 10 days (13.13%, 12.67%, and 12.69% respectively). The ash content also favored Cattle NS at 10 days. Cattle NS at 10 days harvest was significantly (P < 0.05) the highest (7.00%), but comparable (P > 0.05) with Rabbit NS at 10 days for NDF. Fresh and DM yields were highest for Cattle harvested at 10 and 8 days respectively. The study recommends Cattle NS as hydroponic organic NS for sorghum red as it enhances fresh and dry matter yields, and nutritive values.

With the paramount development of industry and agriculture sector, levels of different pollutants like, heavy metal ions, pharmaceuticals, organic dyes, biological waste and other pollutants are becoming serious. The ecosystem and human health suffered greatly from the adverse effects of these pollutants. The disposal of these pollutants has become an urgent issue for the human society. Graphene oxide base nanocomposites have generated an excellent extent of focus as desirable alternatives for the adsorptive elimination of contaminants from aqueous systems owing to their enhanced surface area and multiple functional groups for adsorption. Graphene oxide (GO) as a graphene derivative exhibited superior features as obtainable in a graphene sheet. Moreover, the addition of oxygen functional group at the edges and basal plane of graphene further enhanced the efficiency of the graphene by providing sites for the attachment of different metals on the surface. On the underlying adsorption processes, graphene-based nanocomposites for specific contaminants are designed and currently employed for wastewater treatment. This review presents the ongoing development of GO base nanocomposites and their useful applications, understanding how well graphene-based nanocomposites adsorb pollutants and how that relates to the ways in which pollutants interact with adsorbents is crucial. This study highlights newly developed trends in the creation of graphene oxide based nanocomposites to eliminate different heavy metal ions, dyes, pharmaceuticals, and oils spills from effluent water. The focus is on various graphene oxides nanocomposites application for the removal of different pollutants and regeneration of graphene oxide base nanocomposites after several adsorption cycles. Other challenges and potential directions for designing efficient GO based nanocomposites as adsorbents are also presented along with the problems of current studies.

El concepto de persona en el derecho romano
Authors: Di Pietro Alfredo Gustavo
Published: April 2024

El concepto de persona es el presupuesto de todo el orden jurídico. Sin embargo, en las fuentes jurídicas romanas, el vocablo persona se presenta de manera excepcional, y con un sentido análogo al de caput. Según algunos autores, como Alejandro Guzmán Brito, el concepto procedería del vocablo griego πρόσωπον. Para otros autores como Maurice Nédoncelle, provendría del vocablo etrusco Phersu, el cual habría aparecido en un período histórico anterior al del vocablo πρόσωπον, y estaría vinculado al nombre de la diosa Persepona, en cuyos rituales se utilizaban máscaras. En los textos de Cicerón, el vocablo asume un pleno significado en el que se reúnen la acepción teatral, filosófica y jurídica de la palabra. La posteridad del derecho romano cristiano dará a este vocablo un significado más definido, vinculado al individuo como un ser racional.
Demostración experimental de la reflexión de la luz
Authors: Gómez-Fierro Wilmer A.
Published: April 2024

Cuando un haz de luz incide sobre la superficie que separa dos medios, parte de la luz se refleja y parte se transmite. Comprobar el fenómeno óptico mediante el cual la dirección de los rayos de luz cambia después de incidir sobre la superficie de un medio distinto, constituye el objetivo fundamental de la práctica. Para ello se dirigió en un fino haz de luz hacia un espejo metálico que previamente fue ubicado perpendicularmente a una hoja de papel, se dibujaron los rayos incidentes y reflejados donde se comprobó experimentalmente una equivalencia en la medida geométrica de sus ángulos; situación que también fue evidenciada con el uso de una superficie curva, debido a que está formada por una infinidad de superficies planas pequeñas que son sus elementos. La experiencia permite concluir que el rayo incidente, el reflejado y la normal a la superficie en el punto de incidencia están en el mismo plano.
Roles of Schools and Educators in Supporting Resilience in Young Children after Disasters
Authors: Atkinson Leanne J. , Fowler Teresa Anne
Published: April 2024

The increasing frequency and severity of natural and human-induced disasters have had detrimental effects on global populations, resulting in heightened human suffering and disruptions to social structures. This paper explores the multifaceted impact of disasters, encompassing both natural hazards and unnatural disasters, on children and the role of schools and educators in mitigating these effects. While the immediate concern during crises is children’s safety, there are ways to protect and support resilience in young children.

Schools hold significant importance as centres for education, socialization, and economic development, and their role in disaster response and recovery is crucial. Schools provide a sense of normalcy and continuity for communities affected by disasters. However, many schools lack the necessary preparedness, and physical structure in some cases, to effectively respond to these events, and educators often find themselves as first responders without adequate training.

The paper underscores the need for comprehensive disaster skills training for educators and school staff, ensuring they are equipped to address children’s psychological, emotional, and educational needs before, during and after disasters. Additionally, schools can serve as a ‘place attachment’ for children which aids in disaster preparedness, processing traumatic experiences, and fostering resilience and recovery.

This Bridging the Gap paper highlights the urgent need for proactive measures in education including disaster-focused training, robust disaster management plans, and the integration of resilience-building strategies. By prioritizing children’s well-being and leveraging the pivotal role of schools and educators, communities can enhance their capacity to cope with, respond to, and recover from disasters, ultimately promoting greater overall resilience.

Logistics: More than a List
Authors: Cameron Scott
Published: April 2024

According to Canada’s Incident Command System (ICS), logistics represent the provision of “resources and other services to support incident management” (ICS Canada, 2019). Sometimes referred to as the “getters”, people working in a Logistics Section are faced with the challenge of finding diverse products and services to support efforts on the front lines, within the command centre, and at reception and registration centres. While a comprehensive hazard assessment can be helpful to identify typical resources, in a disaster situation, we never really know what we need until we need it – and then we need it right away.

According to Young (2014), “the logistics and resource management functions of Emergency Management (refer to as EM logistics) have been largely reactive, with little to no pre-event planning for potential demand”. In other words, capacity building is absent. Where logistics planning has been made a priority, it generally appears in the form of updated contact information and vendor lists painstakingly collated annually. This results in a labour-intensive, redundant, and highly ineffective process and outcome. In the constantly changing and dynamic environment of emergency management, maintaining current information is a significant challenge for even the most advanced organizations.

Many organizations conduct emergency management planning and preparations from the corner of their desk as they lack the capacity and resources to dedicate full time attention. Directors of Emergency Management (DEMs) regularly build relationships within their sector and engage “contractors through personal relationships and other channels” (KPMG, 2021. P.130). However, major disaster situations remove the DEM from significant logistics functions, leaving other members of the local EM team to fulfil the Logistics responsibilities. Incomplete paper or digital lists with missing information add time and complexity that can result in missed opportunities to mitigate damage to people and property – especially when the logistics functions are being undertaken by people infrequently engaged in crisis situations.

This article substantiates the need for logistics as a central consideration in building and maintaining networks for connection and collaboration, identifies the value of maintaining comprehensive resource lists as a logistics function, and highlights the significance of building and maintaining local data as part of a solid strategy in preparation for the next disaster situation.

Climate Change, Ecosystem Loss and Flood Risk: Taking Stock using Burlington Case
Authors: Sipos Megan J. , Agrawal Nirupama
Published: April 2024

Extreme weather events, climate change, and biodiversity loss are connected by both cause and solution. The impacts of climate change are already apparent as the frequency and magnitude of extreme weather events are increasing, undermining progress made across the globe toward sustainable development. These impacts are magnified by unsustainable and unplanned development, leading to lost biodiversity and ecosystem services, further reducing the ability of communities to respond and recover. As warming increases, the frequency and intensity of these hazards will also increase while at the same time making it more difficult to adapt to and mitigate disasters—the aftermath of hazards. Nature-based solutions provide opportunities to mitigate and adapt to climate change impacts, reduce the risk of disasters, enhance biodiversity, and build sustainable and resilient communities. They are cost-effective approaches that conserve, restore and enhance the natural environment. Using the 2014 flood event in the City of Burlington (Ontario, Canada), this study takes stock of flood risk in the region and how nature-based solutions provide significant co-benefits toward reducing disaster risks.

Development of Moodle-based Plugin for Automated Essay-Type Grading
Authors: Pradana Fajar , Purnomo Welly , Adillah Atthoriq , Hanggara Buce Trias
Published: April 2024

The essay is an exam requiring a more profound understanding of answering and evaluating the answers. However, if the number of questions and participants increases, this will result in a decrease in the quality of the lecturer's assessment. This prompted the development of a software based on the Moodle plugin named Essay Similarity to assess essay answers based on the similarity between the two documents, namely the answers given and the answer key provided. Moodle was chosen because, after the Covid-19 pandemic, many sectors have shifted to working remotely, including the education sector. This resulted in an LMS like Moodle experiencing an increase in users. As of 2020 yesterday, Moodle users have exceeded 190 million users on more than 145,000 websites. In developing this plugin, the method used is the waterfall method using the PHP programming language. The algorithm used to find similarities between the two documents is cosine similarity. Testing the level of similarity between manual and automatic grading was carried out on four models of essay questions. Based on the test results, the average similarity between automatic grading compared to manual grading is 45.44%.

Published: April 2024

The analysis of electromyography (EMG) signals plays a vital role in diverse applications such as medical diagnostics and prosthetic device control. This study focuses on evaluating machine learning methods for EMG signal analysis, specifically in predicting hand movements and controlling prosthetic hands. In contrast to many existing studies that solely employ a limited set of feature extraction methods, we employ a comprehensive comparison technique that encompasses nine machine learning techniques K-Nearest Neighbor (KNN) , State Vector Machine (SVM ) , Decision Tree, Random Forest, Linear Discriminant Analysis (LDA), XGBoost, Naïve Bayes, Gradient Boosting, and Quadratic Discriminant Analysis (QDA)  and five combination of feature extraction methods (Mean Absolute Value (MAV), Root Mean Square (RMS), Waveform Length, Willison Amplitude, and Skewness). The experimental results demonstrate promising accuracy levels, with the best result method being KNN achieving 96.66% accuracy, SVM achieving 95.83% accuracy, and RF achieving 92.5% accuracy. These findings contribute to advancing the understanding of effective machine learning approaches for EMG signal analysis and provide valuable insights for guiding future research in this field. The study also compares the results with previous studies and showcases the effectiveness of the proposed approach.

This study intends to investigate the ways in which news agencies and writers overstate the risk posed by COVID-19 through the use of a linguistic strategy: overstatement. The President of the United States of America, Donald Trump, will be the primary focus of this research project. The scope of this data is limited to a random selection of two speeches downloaded from YouTube by President Donald Trump. In light of this, the primary objective of this research is to provide a response to the following question: (1) Which linguistic strategies does Trump employ in relation to the COVID-19 pandemic? (3)Which linguistic and rhetorical tools does he utilise more frequently in the course of putting this linguistic tactic into effect? (3) What functions are performed in addition to using exaggeration in his speech?

Published: April 2024

In this study, we used the Non-Equilibrium Green Function (NEGF) and Density Functional Theory (DFT) to analyze the nanoscale electronic properties of silicene and germanene structures, the band structure and Density of State (DOS) for the unit cell of silicene and germanene are found that the energy gap is (0 eV) in both. A comparison was made between silicene and germanene in terms of electrical and thermal properties, by calculating the transmission coefficient T(E) for silicene patterns (Si1, Si2, Si3, and Si4) and germanene patterns (Ge1, Ge2, Ge3, and Ge4). The results show that T(E) decreases with increasing etching depth, which also leads to a decrease in electronic conductivity. Moreover, the value of the Seebeck coefficient (S) increases with increasing drilling depth, and also the sign of S varies from a positive value for (Si1, Si4, Ge1, Ge2, Ge4) to a negative value for (Si2, Si3, Ge3) at Fermi level (Ef) equal to (0 eV). The highest value of the figure of merit is about (1.8) for the Ge4 structure.
Changing the functioning of the article in the history of the German language

The subject of the study is the historical changes in the syntactic structure of the German language; the object of the study is articles. The authors consider in detail the use of definite, indefinite and null articles based on the material of a fragment of the Gospel of Luke, which were published in various periods of the German language: the text of Tatiana, translated by Martin Luther, made in 1545; an adapted version of Luther's translation, published in 2017 and a lightweight electronic version created as a result of deviation from the canonical translation. Particular attention is paid to the frequency of use of articles, the reasons for the increase or decrease in their use, as well as other means of determination. It is established that modern electronic text shows a tendency to decrease nominal groups, which, accordingly, leads to a decrease in articles. The tendency to decrease the zero article is manifested by the early Upper German period; in modern German, there is a displacement of the definite article.  The methodological basis is based on a systematic approach to the interpretation of the phenomena of linguistic ontology in diachrony. The research methods are comparative historical analysis, the method of distributive analysis, quantitative analysis, methods of N. Chomsky's theory of control and binding. The main conclusions of the proposed study are the revealed historical processes in the system of articles of the German language. It was found that at an early stage of language development, the zero article dominated in texts, which significantly narrowed the manifestation of determination. The main burden during this period fell on possessive nominal groups, which primarily included proper names. The definite article was used much less frequently. In nominal groups that are part of the prepositional group, the zero article was mainly used, which eventually led to the creation of stable prepositional constructions with a zero article. The largest number of all types of articles falls on Luther's translation adapted to the modern grammatical structure of the German language, which is associated with the maximum use of nominal groups. What is new is the establishment in modern German of a tendency to reduce the zero and definite articles.

Floods, as recurrent natural disasters, exert significant impacts on both the environment and human settlements. This study focuses on evaluating the flood susceptibility of the Bhadradri Kothagudem district in Telangana, situated within the Godavari River Basin. The research integrates Geographic Information System (GIS) and the Analytic Hierarchy Process (AHP) in a multi-criteria approach to analyze and map flood susceptibility. Landsat-8 data, digital elevation model data and rainfall serve as inputs for assessing the flood susceptibility. The study considers various topographical features such as elevation, slope, roughness, contours and aspect, along with factors like land use land cover, flow accumulation, stream direction, stream network, drainage density, flow length, distance from the river, soil, normalized difference vegetation index and topographic wetness index. These variables are rescaled on a scale of one to five and combined to generate a comprehensive flood susceptibility map of the Kothagudem district using GIS. The AHP is implemented through GIS, assigning weightages on a scale of one to five based on the priority of spatial classes within thematic maps. The flood susceptibility map is produced on a scale of five, designating scale class five as of very high susceptibility and scale class one as low. Scale classes two, three and four represent intermediate levels of susceptibility. The resulting flood susceptibility maps offer valuable insights for disaster preparedness, risk mitigation and land-use planning in the Kothagudem district. The integration of GIS and AHP provides a robust methodology for assessing and visualizing flood susceptibility, enabling informed decision-making for resilient and sustainable development in flood-prone regions.
