    Abstract: The demand for healthy and ready-to-eat products has been growing steadily over the years. However, these products are very susceptible to spoilage and have a short shelf-life. In this research, edible coatings based on edible starch (aloe vera gel) and NaHCO3 were applied on fresh-cut vegetable samples (carrot and potato), and the changes in their bio-chemical properties and microbial changes were monitored during 6 days of storage at 4ºC. Two factor experiments, Factor A; postharvest treatments (different concentration of aloe gel and NaHCO3) and Factor B; two vegetable species (Carrot and Potato) were laid out in a Completely Randomized Design (CRD) with three replications. Different concentration of aloe vera gel and NaHCO3 solutions were prepared as per treatment. The prepared slices of vegetable species were treated with different treatment combinations and stored in 200 g capacity polyethylene bags sealed under air, vacuum or modified active atmosphere and then bio-chemically (Titratable Acidity (TA), Ascorbic Acid (AA) content, Total Soluble Solids (TSS), Reducing Sugar (RS), Non-reducing Sugar (NRS), pH) and microbiologically assessed. Higher rate of edible starch (30%) + NaHCO3 (2%) treated potato (CT12) showed the superior performance on TA (1.290), TSS (5.200% Brix), NRS content (0.340) and pH (4.773% Brix) compare to control and other interaction treatments of the study at 6 days after storage while  untreated potato (T0) showed statistically lower AA (6.575 mg/25 g) TA (0.464) TSS (3.856), pH (3.827) NRS (0.133). Growth of bacterial colonies on NA media had statistically highest (14.00) in untreated potato and lowest (5.00) in T12 treated potato while fungal colonies on PDA media range of 4.00 to 11 at 6 DAS. The study may help small-scale establishments to increase the shelf-life of minimally processed vegetables.

    Abstract: The study aimed to identify the reasons behind spreading fake content through SMP and whether tertiary-level students can identify fake content. The study used a descriptive research design. A simple random sampling technique was used for selecting the sample, and a structured questionnaire used for collecting data where the sample size was 121. The respondents were both male (78) and female (43). The ages of the participants were from 18 to 25. The use rate of SM was 100%, whereas Facebook is the most popular SMP (71.9%). More than 80% of participants use SMPs (Newspaper FB page, Journalists SMP wall, various pages and groups) as their information source. About 92.7% of respondents believe that fake content like news, misinformation, and disinformation spread via social media. Most of these are spread by Facebook (72.7%). Among various reasons, 68 (56.2%) respondents said that the most crucial reason is to endanger opposite political parties. The majority of the respondents said that they could identify fake content. They mention that if the content is news to check whether the news is fake or not, they usually look at the things like a search sources, checking photo and video clips, checking publisher’s websites, noticing published dates, visiting prominent news sites, notice spelling, and language, checking reporters identity, check lascivious words, search disclaimer, search URL, read the headline several times, and use media literacy knowledge. Of the respondents, who join the survey, 50.4% don’t have any idea about fake content identifying tools (Google Advance Search, Reverse Image Search, Tin Eye, Yandex, Bing, Photo Forensics, InVID), and the rest of them(49.6%) know about this tools. More than half of the respondents do not use these tools to identify fake content on social media.

    Abstract: Bangladesh's largest water treatment plant sources its water from the Shitalakshya River, which is facing serious problems of organic pollution and ammonia contamination, particularly during the dry months of November to April. This study examines the extent of organic and ammonia pollution in the river and their relationship with each other. The study analyzed daily samples of raw water quality parameters, such as COD and NH3-N concentrations, from 2013 to 2018 only from the dry months, using standard laboratory methods at Dhaka's largest drinking water treatment plant. During the study period, the global average COD and ammonia concentrations in the dry months were 37.8 and 9.2 mg/L, respectively. These concentrations ranged between 10.6 to 76.3 mg/L and 0.98 to 19.54 mg/L in individual months respectively. The global yearly maximum COD and ammonia concentrations were respectively, ranging from 13 to 127 mg/L and 1.63 to 23.24 mg/L in individual months. These maximum levels occurred in March and April. The monthly minimum concentrations of COD and ammonia varied between 6-42mg/L and 0.17-15.6mg/L, respectively. It is noteworthy that the global average figures are higher than the recommended levels for drinking water sources after conventional treatment. The study found a distinct increasing trend in the maximum values of COD and ammonia concentration over time. Both the average and maximum values increased by around 0.5 mg/L every year. A statistical linear regression between the maximum COD and the ammonia concentration across the years showed an excellent strong correlation marked with an R2 value of 0.93,0.88,0.95 respectively for maximum, minimum and average values, indicating a potential common origin for these pollutants. If this trend of pollution persists, the authorities will need to modify the treatment chain to ensure that the supply of drinking water is not affected.

    Abstract: No company can thrive in the cutthroat business environment of today without effective branding. Because branding makes a company stand out from other companies, it is crucial for all businesses, no matter their size. Due to increased brand awareness and engagement, social media platforms have emerged as essential communication platforms.  Especially Facebook is the most crucial social media in terms of several users and activity. Facebook can be used to reach more people with low costs. So Facebook is a significant medium for brand promotion.  The aim of this research is to investigate the effectiveness of social media as a tool for brand promotion. To employ the study objectives a quantitative content analysis method was used. Researchers purposively select three (Aarong, Yellow, and Le Reve) fashion brands’ Facebook pages in Bangladesh. The study finding depicts that fashion brands Aarong, Yellow, and Le Reve have 3.2 million, 4.1 million, and 2.5 million followers on their Facebook pages. On their Facebook pages, Aarong, Yellow, and Le Reve each posted an average of 2.1, 4.73, and 5.67 posts daily to promote their brands. The posts are usually in the English language and most of the posts use product photos with descriptions. Aarong and Le Reve post more women's clothing, while Yellow focuses more on kid's dresses. All three brands saw higher customer engagement with video. Even with fewer posts on Aarong's page, customer engagement was high. Each post had an average of 2,767.25 reactions on Aarong, 753.56 on Yellow, and 434.22 on Le Reve.

    Abstract: In this age of social media, people are using various platforms for seeking and sharing information. This study aims at exploring the patterns of sharing health information on the widely used social media platform Facebook and the users' engagement with the information. For this purpose, the researchers used mixed-method content analysis. We analyzed 485 Facebook posts about 14 types of issues across nine categories. The study results showed that the highest number (27.84%) of posts were related to health awareness, and the lowest were personal opinions. This paper offers a basis for comprehending the processes of sharing health information and how it could affect user involvements. To clarify the structures that guide user interactions with health content on social media, the study also integrates components from communication and information-sharing concepts. The study thus offers empirical insights into the kinds of health information provided, the most popular health topics, and user engagement patterns through a thorough content analysis of public Facebook postings in Bangladesh. The analysis provides sophisticated knowledge of the issues impacting engagement, including language, kind of material, and multimedia use, by measuring the interactions of users. Scholars can understand from this study how users interact with health-related content in the digital era. The result of this study can be used by academics exploring public health, media studies, and health communication to improve theories and create focused interventions for health communication. Additionally, this research can provide useful information for health practitioners to improve their online communication tactics.

    Abstract: Reliable hydraulic parameters values are essential and crucial basic data for potential groundwater withdrawal (aquifer yield) and also for sustainable groundwater management. They are also essential for simulation model study for different management scenario analyses. The laboratory test has limitations, while in situ tests produce representative aquifer parameters. The pumping test method is the only method that provides simultaneous information on the hydraulic behavior of the well, the aquifer, and the aquifer boundaries. Pumping tests were performed to determine aquifer hydraulic properties such as hydraulic conductivity (K), transmissibility (T), and specific yield (Sy) at two Upazilas of the Barind area, namely Nachol and Niamatpur. The aquifer formation is composed of layers: upper fine sand, medium sand, a conductive sand layer, and lower fine sand at the bottom, below which the impervious clay layer exists. The K was determined through Dupit’s steady radial flow equation, T through Theis’s and Copper-Jacob approach, and Sy through Copper-Jacob and gravity drainage of aquifer materials. The mean K, T, and Sy were found as 30.3 m3/m2/day, 756.7 m3/m/day, and 4.6%, respectively for the Nachol location; and 52.7 m3/m2/day, 1027.3 m3/m/day and 6.6%, respectively for Niamatpur location. The values obtained are supported by regional values reported earlier, and also by other locations’ values situated elsewhere having similar aquifer materials. To achieve long-term sustainability in the studied locations, withdrawal of groundwater resources should be optimized considering the aquifer hydraulic properties values.

    Abstract: Psoriasis is a common, chronic inflammatory skin disease affecting many people of the world now a days. Psoriasis is principally an immunological T lymphocyte-driven disease, relating both the distinctive and T-cell-mediated immune systems. The mostly affected sites comprise the scalp, extensor surfaces of the knees and elbows, umbilicus, genitalia, anterior lower legs and nails. This disease can significantly impact on a patient's quality of life and is connected co-morbidities comprise psoriatic arthritis, obesity and the metabolic syndrome, diseases of cardiovascular system and liver with fats. Provided treatment is depends on disease severity, quality of life, patient preference, relevant co-morbidities and efficacy of the treatment. Treatment such as topical emollients, tar, analogues of vitamin D and corticosteroids are first line for local/mild disease. Psoriasis cannot be fully cured once it affects a person but can be managed by proper taking care of the skin according to the doctors. Patient counseling can also add benefits in the management of psoriasis.

    Abstract: A study was conducted to assess of groundwater and surface water quality of Barisal sadar upazila. Total 22 water samples (11 pond water and 11 groundwater) were collected from January to March, 2017. Samples were slightly acidic in nature and 7 pond water not suitable for aquaculture in respect of pH. Samples of pond were “excellent” and groundwater samples were “good” for irrigation except two high salinity group water for irrigation for EC. Calcium indicates the samples were suitable for aquaculture but 7 samples were not suitable due to higher Mg content. In respect of K, 9 samples were not suitable for aquaculture. Cu concentrations found suitable for all purposes. For Fe and Zn samples are suitable for irrigation and consumption. Chloride showed, samples were not suitable for livestock consumption except 7 ponds sample. Samples are not suitable for aquaculture in respect of Cl, Fe and Zn. For Manganese, samples (except 1) found suitable for consumption. Samples were “excellent” for sensitive, semi-tolerant and tolerant crops in respect of B. Not any samples responded to CO3 test and HCO3 concentrations found normal. All water sources free from Arsenic contamination. Phosphorus concentration in groundwater might not be harmful for multipurpose use. SAR categorized all samples “excellent” class for irrigation except 2 groundwater samples. 15 samples were “suitable”, 3 were “marginal” and 4 were “unsuitable” for irrigation in respect of RSC. For HT, 13 were “moderately hard” and 09 were “hard” limit for irrigation and samples were suitable for drinking and livestock consumption. Asian J. Med. Biol. Res. March 2020, 6(1): 44-55

    Abstract: For proper management of groundwater resources, estimation of groundwater recharge is crucial. Information on groundwater recharge is particularly important in dry areas where groundwater is continuously depleting. In this study, groundwater recharge was estimated at two locations in the dry, Barind area of Bangladesh using the applied tracer, water balance (WB) and water-table fluctuation (WTF) methods. In the WTF method, considerations for drinking and irrigation withdrawal were taken. For runoff estimation in the WB method, a modified form of the USDA-SCS method was used. The results revealed that the average yearly recharge at the Nachol location varied from 104.9–195.8 mm/year under different methods, having a mean of 136.1 mm/yr over the methods. At Niamatpur location, the recharge rate varied from 125.1 to 210 mm (9.9 – 15.1% of yearly rainfall) under different methods, having a mean of 157.6 mm/yr. On average, the WTF method produced the lowest estimate of recharge followed by WB method. Based on the local geological and hydrological settings and the suitability/limitations of the methods themselves, the tracer technique may be regarded as a reliable method for the study area. The information on recharge will help the ‘water resource agency’ and ‘policymakers’ to adjust pumping/irrigation schemes, avoid over-exploitation of the groundwater resource, and ensure the long-term sustainability of the resource in the area.
