No full textCurrently the progress of Information and Communication Technology has been adapted by various government agencies or private, one of the technology that can be used is web, government have used this technology for e-government. The Office of Industry, Trade and SME of Kota Pagar Alam that runs the Market through the Technical Implementation Unit of the Service gives the right to rent at Pasar Dempo Pagar Alam. During this time if there is an empty kiosk, prospective tenants come to the clerk for confirmation and lease submission process. To simplify the management and lease submission process, an application is needed that can facilitate the officer and prospective tenants to interact, while the application will be built is web-based. The purpose of this study design application in the sense of translating the results of the analysis into the form of software packages later Create the system or improve the existing system. To make the proposed system the author uses the steps of Customer Communication, planning, modeling, construction and deployment
New generation washable PES membrane face mask for virus filtration
No full textMembrane materials might be used for face protection because they can decontaminate the inhaled air from particle pollution and viruses like the SARS-Cov0-2 which damages our respiration system. In this study, plyethersulfone membranes (PES) were synthesized with green solvent at room temperature and its filtration effectiveness was investigated against nano-bacteria (size 0.05 to 0.2 µm) by measuring their Bacterial Filtration Efficiency (BFE) and micro aerosol size (0.3 µm), and Particulate Filtration Efficiency (PFE). The average SARS-CoV-2 diameters are between 50 nm to 160 nm. A series of experiments were performed to accomplish between 0.03 to 0.21 µm PES sponge like diameters so that can be used for SARS-CoV-2 filtration. Results showed that nanofiltration/ultrafiltration could filter 99.9% of bacteria and aerosol from contaminated air the size of the Covid-19 molecule.</p

Fabrication of a polyethersulfone/polyethyleneimine porous membrane for sustainable separation of proteins in water media
No full textThis paper aims to establish a new sustainable membrane with antifouling properties by developing a structured porous membrane with a honeycomb-like surface fabricated by blending polymers and additives via immersion precipitation and using a thermally induced phase inversion method coupled with exposure time to vapor. The hydrophilic properties, surface charge, and pore size of the membrane were dependent on controlling the blending ratio of polyethersulfone (PES), polyethyleneimine (PEI), and polyvinylpyrrolidone (PVP). The properties of the membranes were characterized, including physical properties, morphology, contact angle, mechanical properties, porosity, and pore size distribution. The membrane filtration performance was evaluated by examining the water permeation, antifouling, and hydrophilic properties of the membranes. The hydrophilic nature of the PES/PEI membrane increased the filtration performance and created a smooth surface that exhibited excellent antifouling ability. Finally, the separation capability of the membranes was evaluated using bovine serum albumin (BSA) and Angelica gigas Nakai (AGN) root solutions. An almost 99.9% rejection rate was achieved for BSA and AGN at 1 bar pressure. The optimized membrane outperforms the commercial membrane with analogous characteristics on both the water flux and molecular weight cut-off (MWCO) of polyethylene glycol (PEG). Due to the controlled pore size (0.0032 to 0.0041 μm) of the honeycomb-like surface, it may be possible to separate pharmacodynamic macromolecules (such as berberine, baicalin, geniposide, and palmatine) for future applications.</p
Sustainable Membrane Technologies for By-Product Separation of Non-Pharmaceutical Common Compounds
No full textThe Chinese pharmaceutical industry and traditional Chinese medicine (TCM) are both vital components of Chinese culture. Some traditional methods used to prepare TCMs have lost their conformity, and as a result, are producing lower-quality medicines. In this regard, the TCM sector has been looking for new ways to boost productivity and product quality. Membrane technology is environmentally-friendly, energy-saving technology, and more efficient than traditional technologies. Membrane separation is the most effective method for separating and cleaning the ingredients of the non-pharmaceutical common compounds from traditional Chinese medicine (TCM). Membrane technology is currently being employed for the concentration, purification, and separation of TCMs. This review paper discusses how membranes are fabricated and their role in non-pharmaceutical common compound separation and TCM purification. Accordingly, the membrane applicability and the technological advantage were also analyzed in non-pharmaceutical common compound separation. Researchers pay attention to the choice of membrane pore size when selecting membranes but often ignore the influence of membrane materials and membrane structure on separation, resulting in certain blindness in the membrane selection process
Teacher Candidates' opinions about Augmented Reality(AR) as a supplemental educational tool
No full textThis poster was presented by Alam, I., Teacher Candidates' opinions about Augmented Reality(AR) as a supplemental educational tool. Presented at 10th Annual Graduate and Professional Student Conference, held at Memorial Union, Ames, IA, April 6 2022. Posted with permission.In recent years, augmented reality (AR) technology has been widely proposed as innovative technology. AR technology superimposes digitally simulated information on the physical environment, which can be a unique element for learning experiences. Despite the potential of AR, there has been relatively little integration of AR into the
classroom. The purpose of this pilot study is to examine the acceptance and intentional use of AR technology by teacher candidates and their opinions of AR as a supplemental educational tool. The study has utilized a phenomenological design that is comprised of System Usability Scale survey and interview questions. Based on the participants' answers, research data has been analyzed and discussed
Anthelmintic resistance to cattle gastrointestinal nematodes in selected dairy farms of Mymensingh and Sirajganj districts of Bangladesh
No full textCorrection: Table 1 and Table 2 have were omitted from the PDF in error. They were added to page 89 on 17th May 2018.Anthelmintic resistance (AR) to commonly used dewormers is one of the major world-wide constrain in livestock production. The present study was investigated the status of AR in BAU dairy farm, Mymensingh and Talukder dairy farm, Sirajganj. Faecal egg count reduction test (FECRT) was applied to assess AR in cattle of two dairy farms during January to June 2017. The anthelmintics tested were Albendazole (ABZ), a benzimidazole anthelmintic (Almex®, Square Ltd.) and Ivermectin (IVM) (Vermic®, Techno drugs Ltd.), administered at the doses recommended by the manufacturers. In each farm, cattle were divided into treatment and control (not treated) group based on faecal egg counts (FEC), that is at least 200 eggs/g. At 14 days after treatment, faecal samples were collected for post-treatment FEC, which is compared between treatment and control group. Resistance was defined if there was <95% reduction, with lower 95% confidence limit (CL) <90% in the FEC. AR was present in both the dairy farms involved in this study. The FECRT using ABZ revealed 79.7% (95% CL 87.9, 65.8) reduction and 95.8% (95% CL 98.7, 87.1) reduction of FEC in BAU and Talukder dairy farms, respectively. Also, FECRT using IVM revealed 77.9% (95% CL 97.7, 85.5) and 94.2% (95% CL 97.7, 85.5) reduction of FEC in BAU and Talukder dairy farms, respectively. Our study suggest that AR is present in both selected dairy farms and further extensive studies are required to determine the extent of AR in different cattle farms of Bangladesh.Res. Agric., Livest.
