A facile electrochemical sensor based on single-walled carbon nanotubes/magnesium layered hydroxide-3-(4-methoxyphenyl) propionate nanocomposites paste electrode (MWCNT/MLH-MPP) for determination of bisphenol A (BPA) and uric acid (UA) was constructed in this study. According to experiments, several parameters affecting the electroanalytical responses of the prepared electrode were optimised, such as amount of modifier, square wave voltammetry parameters, and pH effect. Under optimum experimental conditions, electrochemical current of BPA and UA oxidation were linearly proportional to the concentrations from 3.0 ? 10?7 M to 1.0 ? 10?4 M and 1.0 ? 10?7 M to 1.0 ? 10?4 M for BPA and UA respectively with the both limit of detection of 5.0 ? 10?8 M. The small percentage of relative peak currents changes with added some interference indicated that the modified electrode can be used for the determination of BPA and UA in real samples such as baby teether and urine. ? 2021.

Distance learning is the final alternative in realizing sustainable education during the Covid-19 period. The distance learning model will not face serious problems for areas that have a strong internet network, but distance learning will face various problems for areas that do not yet have an Internet Server Provider (ISP). Therefore, this study aims to reveal how the learning model was carried out during covid-19 in non-ISP areas, especially for Islamic religious education subjects. The research was conducted with a qualitative approach, data collection techniques were observation, interviews, and documentation studies. The results of the study are that Islamic religious education teachers in areas where there is no internet carry out distance learning through: first, learning plans are made according to the conditions when learning takes place remotely. Second, the implementation of distance learning in non-ISP areas is that teachers provide information on information boards in scho.....

This  research  aims  to  produce  visual  artwork  through  identity  interpretation  and political  culture  in  Bangladesh.  This  concept  manifests  a  sense  of  the  process  of  expressing Bangladesh's unique identity by making a subtle difference with India. The main  objectives focusing on the Bengal tradition and symbol with artistic practices in pre and  post-liberation in Bangladesh and the evolving current  scene. The reference artists within this  research project  are Safiuddin Ahmed, SM Sultan, Zainul Abedin, Maqbool Fida Husain, Melanie Hava,  Quamrul Hassan, and Shahabuddin Ahmed. The justification  of selected  this  artist  because  they  are  producing  the  issues  of  identity interpretation in Bangladesh's political scenery. The  reference of artworks carried out a suggestion on how the combined traditional folk art and modern  aesthetic framework with specific symbols had been produced. A studio practice metho.....
