Due to this uncertainty, it is essential to identify a suitable equation to predict the dissolved oxygen (DO) concentration of the river in concern. Pusu River in Malaysia receives sewage discharges and suffers from land-clearing activities and stormwater-related pollution. Pusu River is a small river, but highly important in terms of demography and geographic location. As such, it is required to identify a suitable reaeration rate equation for predicting its DO concentration, which indicates the overall health of a river. The purpose of this study is to assess the suitability of reaeration rate equations to predict Dissolved Oxygen (DO) concentrations of the Pusu River. The water quality analysis simulation program (WASP) model was employed to model the DO of the Pusu River. Reaeration rates calculated from the available 31 equations were given input in the model, and errors in prediction were calculated in terms of Root Mean Square (RMS) error and R2 for every equation. It was revealed that Neguluscu and Rojanski (1969) equation using depth and velocity as the variables performed best among all the equations. It produced a minimum RMS error of 0.17 and 0.09 mg/L in calibration and validation data, respectively. R2 values for predicted-observed plots were 0.98 and 0.97 in these two data sets using the equation. Based on overall Performance Indicator Values (PIVs), reaeration rate equations with depth and velocity as the variables performed better than the other equations with more variables for Pusu River. This study provided important information to accurately model the DO of the Pusu River for future simulation of different scenarios.","PeriodicalId":503593,"journal":{"name":"ASM Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139143842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to examine the publication patterns and annual growth rates related to urban pollution in the Scopus and Web of Science (WoS) databases. The comprehensive analysis encompasses productive countries, network connectivity, proactive institutions, and research keywords examined through ScientoPy and VOSviewer. This analysis revealed a fluctuating trend in urban pollution research in both databases from 1990 to 2021. Nonetheless, there was a notable surge in publications on the WoS database after 2008. Within the scope of this study, \"Environmental Science and Ecology\" has been identified as the most pivotal subject area. This study indicated that scholars from France, Brazil, the United Kingdom, Germany, Canada, the United States, and China collaborated extensively, establishing robust research partnerships. The keyword “Urban pollution” has become the most prevalent, followed by “Pollution” and “Air pollution”. This study is subject to certain limitations, primarily from its reliance on the Scopus and WoS databases, which consequently influenced the data quality. Nevertheless, the study elucidates prevailing trends in urban pollution research, offering guidance to practitioners, prospective researchers, and policymakers in formulating novel concepts and a research agenda conducive to sustainable environmental dimensions.","PeriodicalId":503593,"journal":{"name":"ASM Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139146167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

E-learning is facilitated by various platforms, such as Zoom, Youtube, and Spada, to enhance the development of creative thinking abilities. There is a belief that comprehension is a crucial factor that must be present to support it. Based on this, the research aims to examine the impact of comprehension on the ability to think creatively during the learning process, as well as the influence of comprehension on the final exam through the mediation of creative thinking skills. Additionally, the study will explore the relationship between comprehension and creative thinking skills in the learning process. The research methodology employed is quantitative research, which primarily involves the statistical analysis of numerical data and also provides further insights into the questionnaire and interview data. Comprehension has a significantly positive impact on measures of creative thinking capacity; comprehension has a beneficial impact on performance in final examinations. By utilising thinking ability indicators, there is a positive correlation between creative thinking and comprehension with all indicators of creative thinking ability, resulting in an enhanced contribution to favourable learning outcomes.","PeriodicalId":503593,"journal":{"name":"ASM Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139144459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The elements of a hazard are often interpreted with varying connotations, especially flood hazards. In fact, the characteristics and scales that measure a flood hazard level also vary from one study to another. Therefore, the aim of this paper is to understand the characteristics of flood hazards and their influence on the risk of loss level by reviewing previous research. Generally, the flood hazard level can be determined according to certain characteristics, such as depth, velocity, duration, amount of discharge, flood flow force, flood intensity and energy head. Based on these characteristics, the flood hazard level can be classified into three or four levels: low, medium, high; or low, medium, high and extreme. From the aspect of depth, for example, floods with a height less than 0.5 meters and more than 1.5 meters are categorised as low and high hazard levels, respectively. In terms of frequency, floods that occur less than 6 times a year are considered as low hazard level, while those that occur more than 11 times a year are classified as extremely hazardous. The higher the flood hazard level in an area, the greater the risk of loss. Therefore, understanding the characteristics of a flood hazard will aid in determining or assessing the risk of loss in any particular area.","PeriodicalId":503593,"journal":{"name":"ASM Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139152780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Liquid-liquid extraction (LLE) and solid phase extraction (SPE) were employed to extract nitrofurans residue for the optimal purification and cleaned up procedures. In this study, a good linearity with the coefficient of determination R² value of 0.9951 – 0.9972 mg/L with the concentration range of 1 to 50 mg/L nitrofuran antibiotics was achieved. The relative standard deviation (RSD) for triplicate nitrofurans assay were less than 10.0 %. The limit of detection (LOD) and limit of quantification (LoQ) of furazolidone, furaltadone and nitrofurazone were found to be in the range of 2.37 – 10.56 mg/L and 7.17 – 31.99 mg/L, respectively.
