Aim: Gaining understanding of the knowledge, perception, and practice of substance abuse among Adolescent in southwest Nigeria. Study Design: A non-experimental research design was used for the study, and a total of 133 respondents were selected from cross sectional administered questionnaire in selected secondary schools in Owo Metropolis, Ondo State, Nigeria. The study was carried out at Achievers University Owo, Southwestern Nigeria. Methodology: Questionnaire from the respondents was used, was simple comprising of logically and easily understandable questions relating to the topic and answering the research question. The questionnaire was made to measure what it is supposed to measure as accurately and consistently as possible. The statical results of the descriptive data were obtained using the Statical Package for Social Sciences (SPSS version 20) and relevant descriptive and inferential statistical method was employed. Results: The results revealed a total of 133 students from four different schools in Ile-East Local Government area in Ondo State, Nigeria. The demographic data showed that there were more males among these schools representing 60.2% of the entire sample size. Majority of the sample size also showed between 15 and 16 years old representing 47.4% and 21.8% respectively. 91.7% of them had received information about substance abuse, most of them from their peers (49.6%) and school (27.8%). 78.2% of the respondents indicated, that they had never used psychoactive substance before, majority gave several reasons such as it is a bad for their health which took most reason (38.3%), other reasons include fear of the repercussions (11.3%), and other gave no reason (17.35). Minority of them admitted having used psychoactive substances at a time (21.8%) and 125 of this minority agree that they used it occasionally, when it is available and at parties. 34.6% of the respondents had a family members that abuses drugs or other psychoactive substances, most of them were relatives (15.8%) and their fathers (12.8%), which shows influence family members and relatives have on substance abuse. Conclusion: The adolescents were analyzed to have fair knowledge of substance abuse, its effect as well as a fair attitude towards it.

This study explored the lived experiences, strategies, best practices, and suggestions of reading teachers in teaching reading in the Montevista District, Davao de Oro. Utilizing a qualitative-phenomenological research method, data were collected through random sampling from eight reading teachers across four participating schools using individual in-depth interviews. The results revealed that reading teachers experienced difficulties in teaching reading, primarily due to the lack of early phonological awareness instruction in the lower grades. Additionally, the study identified several effective teaching strategies, including the use of individualized teaching methods, video materials, and the early introduction of phonological awareness. Based on these findings, it can be concluded that emphasizing phonological awareness at an earlier stage, regularly following up on learners' development, and involving parents in understanding their child’s reading skills and progress are crucial. The study recommends that the reading coordinator of Montevista District in Davao de Oro implement more diverse reading strategies, provide additional materials, and offer more training opportunities for teaching reading.

This research studied the heat effects of topochemical esterification of cellulose, namely, nitration and acetylation. Depending on the conditions, the esterification process can occur in two main topochemical directions: bulk and local. In a bulk process, the reagent reacts with both amorphous domains (ADs) and crystallites (CRs) of cellulose. However, in local esterification, the reagent reacts with the most accessible ADs only, whereas CRs remain almost unreacted. It has been established that the bulk nitration of cellulose to a substitution degree (DS) of 1.5 is endothermic and determined primarily by the temperature-entropy component of the Gibbs potential. However, the reaction of bulk nitration of cellulose to higher DP values becomes exothermic; thus, the feasibility of this reaction is determined by the enthalpy component of the Gibbs potential. Unlike nitration, the bulk acetylation of cellulose is always an exothermic process, regardless of the achieved degree of substitution; therefore, this esterification process can probably be implemented due to the reaction enthalpy's predominant contribution to the Gibbs potential. In the case of local esterification of ADs, the main contribution to the negative Gibbs potential is made by the exothermic enthalpy of the reaction. Besides, the local acetylation is more exothermic than the local nitration process. Since the locally substituted esters are copolymers of amorphous hydrophobic ester and crystalline cellulose, these esters should be significantly less hydrophilic than cellulose. Therefore, it can be expected that local esterification will find a wide practical application for the inexpensive hydrophobization of various cellulose materials.

Objectives: This survey explores how patients with inflammatory rheumatic diseases perceive the COVID-19 vaccine and what factors influence their decision to get vaccinated. Methods: This anonymous phone survey employs a cross-sectional design to gather data from adult Moroccan patients (over 18 years old) diagnosed with chronic inflammatory rheumatic diseases (CIRD), including rheumatoid arthritis (RA), spondyloarthropathy, and undifferentiated CIRD. Results: A total of 321 participants responded to the questionnaire. The mean age of patients was 47.6±12 years and women represented 65.7% of the study population. The intention to vaccinate against Covid-19 was reported in 34.6% of the cases. Beliefs that Covid-19 vaccines were man-made, and that they are intended to inject microchips into recipients and that the vaccines were made to force people to get vaccinated were found in 22.7%, 3.2% and 8.7% of respondents, respectively. In univariate and multivariate analysis, the conspiracy beliefs that were associated with vaccination intention were the idea that Covid-19 vaccine was made to force people to get vaccinated (p<0.001) and to reduce world’s population (p<0.001). Conclusion: The study revealed a low vaccination intention against COVID-19 among Moroccan CIRD patients. This association between COVID-19 vaccine conspiracy theories and vaccine hesitancy highlights the need for targeted awareness campaigns to combat misinformation and improve vaccine acceptance within this population.

The current research shows the analysis of the quality of groundwater close to a landfill in Lucknow City, in Uttar Pradesh, India. Calculating the leachate pollution index (LPI) and water quality index (WQI) has been done to evaluate the quality of the groundwater and the leachate near the site. A very high value of LPI (27.54) indicates that there was a substantial amount of contaminants at the landfill site. the calculation of WQI for the groundwater samples has been done and a map for showing its spatial distribution has been prepared for the analysis of the WQI, revealing that 40% of the groundwater specimens are excellent alongside 60% of the groundwater is in a good category. the spatial distribution of WQI illustrates that the majority of the region around the site of the landfill is in the good category and the remaining is in the excellent category. The experimental result of the physicochemical analysis for groundwater revealed that water is satisfactory and fit for drinking and other domestic use and only some parameters like total alkalinity, total hardness, EC, TDS, sodium, magnesium, calcium, and sulfate are above the desirable limit set by Indian standard (IS10500: 2012). This study also emphasizes the importance of LPI and WQI as a monitoring tool for the policymakers and the government body for preventing and safeguarding the risk of groundwater contamination from leachate.

Calculating the leachate pollution index (LPI) and water quality index (WQI) has been done to evaluate the quality of the groundwater and the leachate near the site. A very high value of LPI (27.54) indicates that there was a substantial amount of contaminants at the landfill site. the calculation of WQI for the groundwater samples has been done and a map for showing its spatial distribution has been prepared for the analysis of the WQI, revealing that 40% of the groundwater specimens are excellent alongside 60% of the groundwater is in a good category. the spatial distribution of WQI illustrates that the majority of the region around the site of the landfill is in the good category and the remaining is in the excellent category.

This study explores educators' understanding of the rationale for Civic Education to be taught as a compulsory subject to learners in secondary schools in Zambia, as enshrined in the national policy on education. The study was conducted in all secondary schools of Kabwe district, guided by the Advocacy Coalition Framework Theory (ACF). Using a mixed-method approach within a pragmatic research paradigm, data were collected from 239 participants. Quantitative insights were derived from 215 respondents across 32 selected schools, including head teachers, heads of Social Science departments, heads of Civic Education sections, and Civic Education teachers who completed an online questionnaire. Qualitative data involved interviews with 24 educators and 2 Ministry of Education officials, supplemented by document analysis of national policy and curriculum frameworks. Findings underscore a robust awareness among educators of Civic Education's role in fostering informed citizenship and preparing learners for democratic engagement, focusing on four themes: (1) cultivating informed learners, (2) promoting good citizenship and social cohesion, (3) preparing learners for political engagement, and (4) enhancing critical thinking skills. Additionally, findings may inform policy and practice. Recommendations include enhancing professional development through targeted training programs, ensuring curriculum alignment with national policy frameworks, promoting interdisciplinary collaboration among departments, and establishing mechanisms for ongoing program evaluation to ensure effectiveness and continuous improvement. These recommendations aim to strengthen compulsory Civic Education implementation in Kabwe District, Zambia, fostering a knowledgeable and engaged citizenry capable of contributing positively to society.
