The purpose of this study was to create an e-flipped classroom learning paradigm to help mathematics students enhance their higher order thinking skills. This study is a research development, often known as R&D. In this study, the development model proceeded through the stages of conceptual model, theoretical model, hypothetical model, and final model. The learning devices created in the form of prototypes are restricted to eight disciplines as a consequence of the design of learning devices achieved. The method for building the e-flipped classroom model to increase higher order thinking abilities is separated into three stages: pre-development activities, development activities, and model implementation activities. Validation sheets, observation sheets, questionnaires, and assessment sheets were utilized as study instruments. Validity, practicability, and effectiveness data analysis approaches are employed. The study's findings show that: (1) the e-flipped classroom model was developed to improve the parts that have been obstacles to its use thus far; (2) the flipped classroom model is not only a combination of online and offline but also allows for full online conditions; (3) the model is designed to train students' high-level thinking skills through several supportive activities; and (4) the devices used. Thus, based on the study findings, the e-flipped classroom concept and its learning aids satisfy the requirements for being valid, practical, and successful.

This study aims to provide baseline data about soil contamination by some heavy metals at different depths around landfills in areas at high risk of groundwater contamination. Soil samples were taken in three replicates at depth of 0 – 20 cm, 20 – 40 cm and 40 - 60 cm in the radiuses of 0 to 10 m, 10 to 20 m and 20 to 30 m around landfills. In all, 81 homogenized composite soil samples were collected. The heavy metals were measured in soil samples by atomic absorption spectrophotometer. The results show that the concentration of mercury (0.03 – 0.29 mg kg-1), cadmium (0.04 – 0.69 mg kg-1), arsenic (0.05 – 2.30 mg kg-1) and nickel (0.05 – 2.35 mg kg-1) in analyzed soil samples were lower than the limit values set by WHO, Finland and Dutch environment ministries. However, lead concentrations (90.15 – 129.14 mg kg-1) in topsoil in vicinity of landfills in Amoutivé and Akodesséwa were above reference values set by WHO, Finland and Dutch environment ministries. As the heavy metals may be leached to reach groundwater, the landfills management must be great concern to municipal authorities. The frequent monitoring of the quality of soil and groundwater will be necessary to follow the level environmental contamination by heavy metals around landfills and the possible initiate remedial measures.

Background: A Multiple drug resistance (MDR) in pathogenic bacteria has become a significant public health issue for treatment. Among bacteria, Pseudomonas is another important genus except Streptomyces and Bacillus in production of antimicrobial compounds. The current study aim to to determine the antibacterial activity and preliminary characterization of antibacterial compounds produced by Pseudomonas species such as BB1D11, BN2D41, TG1D11, TR1D41, LH1D11 and TN1D41. Method: The antibacterial activity was checked by using bio autography method as well as agar well diffusion method, against four multiple drug resistant bacteria including three Gram negative bacteria (E.coli, Acinetobacter and Pseudomonas) and one Gram positive bacterium (Methicillin Resistant Staphylococcus aureus). Isolation test showed good activity against all the four MDR bacteria, by producing clear zone of diameter from 2mm up to 20mm. Optimum temperature for growth and antibiotic production of Pseudomonas BB1D11, BN2D41, TG1D11, TR1D41, LH1D11 and TN1D41 was 37C0. It produces more metabolites when subjected to shaking incubation. In thin layer chromatography, the extracts were repeatedly inserted on a silica gel coated plate, which was run in mobile phase. Normal HPLC was perform to reveal the presence of antibacterial compounds. Results: By well diffusion assay a zone of inhibition range from 2-18 mm of diameter against different test bacteria. The components were separated, resulting in the formation of bands with different colors, each showing a different compounds. Biological screening was performed by bio autography, metabolites showed a significant activity at retention factor of 0.89. While HPLC at retention time 2.50-2.90 showed presence of significant antibacterial compounds. Conclusion: Pseudomonas BB1D11, BN2D41, TG1D11, TR1D41, LH1D11 and TN1D41 showed promising anti-microbial activity against different MDR bacteria. It is concluded that HPLC revealed the presence of DAPG at retention time 2.90 which inhibit the growth of MDR bacterial strains.

Afridi","doi":"10.24203/ajas.v9i5.6718","DOIUrl":"https://doi.org/10.24203/ajas.v9i5.6718","url":null,"abstract":"Background: A Multiple drug resistance (MDR) in pathogenic bacteria has become a significant public health issue for treatment. Among bacteria, Pseudomonas is another important genus except Streptomyces and Bacillus in production of antimicrobial compounds. The current study aim to to determine the antibacterial activity and preliminary characterization of antibacterial compounds produced by Pseudomonas species such as BB1D11, BN2D41, TG1D11, TR1D41, LH1D11 and TN1D41. \u0000Method: The antibacterial activity was checked by using bio autography method as well as agar well diffusion method, against four multiple drug resistant bacteria including three Gram negative bacteria (E.coli, Acinetobacter and Pseudomonas) and one Gram positive bacterium (Methicillin Resistant Staphylococcus aureus). Isolation test showed good activity against all the four MDR bacteria, by producing clear zone of diameter from 2mm up to 20mm. Optimum temperature for growth and antibiotic production of Pseudomonas BB1D11, BN2D41, TG1D11, TR1D41, LH1D11 and TN1D41 was 37C0. It produces more metabolites when subjected to shaking incubation. In thin layer chromatography, the extracts were repeatedly inserted on a silica gel coated plate, which was run in mobile phase. Normal HPLC was perform to reveal the presence of antibacterial compounds.\u0000Results: By well diffusion assay a zone of inhibition range from 2-18 mm of diameter against different test bacteria. The components were separated, resulting in the formation of bands with different colors, each showing a different compounds. Biological screening was performed by bio autography, metabolites showed a significant activity at retention factor of 0.89. While HPLC at retention time 2.50-2.90 showed presence of significant antibacterial compounds.\u0000Conclusion: Pseudomonas BB1D11, BN2D41, TG1D11, TR1D41, LH1D11 and TN1D41 showed promising anti-microbial activity against different MDR bacteria. It is concluded that HPLC revealed the presence of DAPG at retention time 2.90 which inhibit the growth of MDR bacterial strains.","PeriodicalId":8497,"journal":{"name":"Asian Journal of Applied Sciences","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88595217","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}
