Coronavirus infectious disease 2019 (COVID-19) first reported in Wuhan, China, causes serious respiratory illnesses such as lung failure and pneumonia. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) the pathogenic agent of COVID-19 has been confirmed as a novel coronavirus. WHO announced COVID-19 a global pandemic and now the whole world is eagerly waiting for vaccines and therapeutic treatment to get rid of this unstoppable coronavirus. As COVID-19 infection, a global threat creates unwanted human casualties and serious economic loss. To stop the ongoing uncontrolled situation researchers are racing to develop prevention and treatment strategies. Vaccines of different countries are in clinical and preclinical trials and the repurposed-drugs are providing to find out a positive result against COVID-19. The report is an analysis of published information focusing

Pabna is one the most densely populated town with poor transport infrastructure in Bangladesh. Here huge pedestriangathers in roads and intersections in CBD （Central Business District） area mainly for commercial and business purposes. At present,pedestrian facilities are one of the greatest challenges in terms of traffic and safety for the urban dwellers. The footpath, zebra rossing,road intersection, walkways, parking and other facilities are the major part of road transportation system as well as pedestrianfacilities and people have to pass walking distance to reach their destinations, before and after use of transport mode. For instance,this paper tries to emphasize the problems of pedestrian facilities and to explore the qualitative level of comfort for the pedestrians ofthree selected intersections namely Traffic More, Indra More and Nimtola More in CBD area of Pabna Municipality through primaryand secondary data. However, about 60% trips are making on foot every day, but the pedestrians are facing many problems whileusing the walkways. Pedestrian crossing behaviors were also observed by using pedestrian volume survey and the survey exploresthat pedestrian crossing rate at these intersections is about 5,000 to 7,000 per hour at a peak period and average 15% to 25% illegalcrossing occurs at those intersections. The physical observation and data from the questionnaire survey also indicate that informalbusiness on the footpath, illegal parking, illegal vendor on walkways, physical obstacle, poor lighting facilities and geometricproblem of the road intersection makes uncomfortable situations for the pedestrian day by day.

An ethno-medicinal investigation was conducted to understand the traditional knowledge of medicinal plants being used by the Maninuri tribe in Bangladesh. The present study was done through structured questionnaires in consultations with the tribal practitioners. A total 32 plant species belonging to 26 families and 29 genera were found to use for Curing 37 ailments. Results show that the use of aboveground plant parts was higher （86%） than the underground plant parts （14%）. Leaf was used in the majority of cases for medicinal preparation （17 species） followed by bark, fruit, root/rhizome, whole plant, seed and flower. Among the 32 plant species, they were mainly used to treat dysentery （10 species）, followed by fever and rheumatism （5 species each）; asthma, constipation, wounds and skin diseases （4 species each）; cold ailments, cough and diarrhea （3 species each）. The study revealed that 72% plant species investigated were used to cure more than one ailment. About 75% medicinal plants were taken orally followed by externally （9%） and both orally and externally （16%）. The study thus underscores the potentials of the ethno-botanical research and the need for the documentation of indigenous healthcare knowledge pertaining to the medicinal plant utilization for the greater benefit of mankind.

Commelina diffusa Burm. F. is a herbaceous tropical plant with different traditional medicinal uses. Present study is aimed to isolate the bioactive compounds from DCM-Methanol extract of the powdered whole plant of Commelina diffusa and to investigate the cytotoxic, antimicrobial and antioxidant activities of the crude extract and its twelve vacuum liquid chromatographic fraction (CD1-12). Vacuum Liquid Chromatography (VLC) was employed to isolate bioactive metabolites. The physicochemical properties of the isolated compound were examined and the molecular structure was elucidated by NMR spectroscopy.?Cytotoxic, antibacterial, antioxidant activities were evaluated following brine shrimp lethality bioassay, disc diffusion method and DPPH free radical scavenging assay respectively. The isolated compound was identified as steroid (stigmasterol) which had significant cytotoxic effect on vero cell line. The crude extract and its fractions (CD8-CD12) exhibited strong cytotoxicity in brine shrimp lethality bioassay having LC50 values 3.79, 9.19, 29.49, 16.60, 19.36, 44.58 μg/mL respectively. The crude extract showed mild to strong antibacterial activity. Fractions (CD5-CD12) showed mild to strong antibacterial activity against Escherichia coli in comparison with Kanamycin (standard). Strong antioxidant activities were found in crude extract (IC50 value 30.52 μg/ml), CD11 (IC50 value 39.27 μg/ml) and CD12 (IC50 value 19.50 μg/ml). The study suggests Commelina diffusa plant extract to have strong antioxidant and cytotoxic activity which is indicative of presence of compounds with broad spectrum of curative applications. One compound namely stigmasterol has been isolated from the plant.

Washing is considered as the final process of garments finishing. Acid washing is one kind of finishing treatment used for making sewn garments aesthetic, fashionable, soft, comfortable and also adding value to the final garments. This paper investigates the effect of the acid washing (with thermocol balls and potassium permanganate) on different physical properties of three knitted garments (Single Jersey 100% Cotton T-shirt, Single Jersey 95% Cotton 5% Spandex T-Shirt and 1 × 1 Rib100% Cotton T-Shirt). Typical washing procedures and techniques were followed and then physical properties were analyzed under standard condition. It is observed that fabric weight, CPI, WPI, spirality and shrinkage increase while bursting strength, stitch length absorbency decrease after washing treatment. pH of all the samples is under controlled and lies between 7 to 8. There is no change in pilling, colorfastness to wash, water and dry rubbing while a little bit decrease in wet rubbing.
