Du Shuhuan,Ariful Islam G. M.,Xiang Rong,Yang Xiaoli 한국기상학회 2021 Asia-Pacific Journal of Atmospheric Sciences Vol.57 No.1

Modern dust plays essential roles in marine sediments, providing nutrient and crucial elements for primary productivity and aquatic ecosystems. However, present marine atmospheric dust observational evidence concerning the biogeochemical response to dust deposition process is spared for a long time. Here a total of 147 aerosols samples were collected near the northern South China Sea (SCS) coast between 13 February, 2016, and 12 February, 2017, have been investigated for the grain size distribution, depositional flux, ten-day back trajectories, clusters analysis, combining with primary productivity (Chlorophyll-a concentration) to indicate the present-day dust deposition process and biogeochemical impacts in the northern SCS on the first time. Our results illustrate the deposition flux and grain size distribution change in different season, grain size distribution in winter are coarser particles than that in the summer, while the maximum and minimum dry deposition flux are 12 December, 2016, (60.4 mg m−2 d−1) and 26 August, 2016, (5 mg m−2 d−1), respective. In addition, the back trajectories and three clusters analyze results indicating 53% of air masses originating locally near the coastal areas of China from the marine boundary layer (0–0.5 km) in the summer monsoon, while 48% dust from the northeast wind is prevailing during the winter monsoon over a relatively higher level (0–1.5 km). Furthermore, an apparent Chl-a blooming after aeolian dust input with a period of 1–2 days in the SCS. Therefore, atmospheric dust contains readily bioavailable iron and enhance the biogeochemical impact in the oligotrophic SCS.

Although corporate social responsibility (CSR) is an extensively studied topic, its determinants in the field of Islamic banking are scarce. In Bangladesh, CSR plays a vital role in gaining customer loyalty and confidence. Therefore, this research aims to identify and analyze the influence of the Shariah Supervisory Board (SSB) and the Shariah Audit Committee (SAC) on CSR adoption in Islamic banks in Bangladesh. The study population is managers and second managers of 160 Islamic bank branches of different commercial banks in Dhaka, Bangladesh. The sampling technique used is convenience sampling where the first available primary data source was used for the research without additional requirements. The study developed a survey questionnaire from examining previous related studies in Islamic banking and CSR context. The final sample size in this research was n = 309, indicating the survey response rate was about 97%. The study used SPSS 23.0 software to interpret the statistical findings, and the findings revealed that support from the SSB and the presence of a strong and effective SAC has a strong correlation with CSR adoption and significantly influence CSR adoption in Islamic banks in Bangladesh. Finally, the study proposes several significant and crucial policy guidelines for Islamic bank branches to adopt CSR activities.

Salmonellosis is one of the life-threating diseases of goat in Bangladesh. Therefore, the present study was designed to study the prevalence of Salmonellosis, and isolation and characterizations of the Salmonella spp. from apparently healthy and diarrheic goat. A total of 47 faces samples were collected from selected place and cultured onto different prescribed medium to isolate it. In this study, 12.76% (6/47) samples were found to be positive for Salmonella spp. During culture on SS agar medium, all of the Salmonella isolates produced round, smooth, opaque, translucent and black color colonies on SS agar media. All of the isolated Salmonella spp. fermented dextrose, maltose and mannitol with production of acid and gas but did not ferment sucrose and lactose. However, these isolates had showed Indole and Voges-Proskauer test negative, Methyl-Red test positive. All of these isolates were subjected to rapid plate agglutination test with polyvalent “O” (Poly ‘O’) and polyvalent “H” (poly ‘H’) antisera where positive agglutination were observed. They were highly sensitive to ciprofloxacin, spiramycin and gentamycin; moderately sensitive to oxytetracyline, streptomycin and amoxicillin; less sensitive to sulphamethoxazole and resistant to penicillin-G. Based on the present findings, it may be concluded that the investigated Salmonella spp. from goats might be S. typhimurium, S. enteritidis, S. brandenburg, S. salford, S. newbrunswick, S. newport or S. dublin. Further study will be needed, therefore it requires further characterization using other serological and molecular techniques.

The study was carried out to evaluate the diagnostic efficacy of the tube agglutination test (TAT), enzyme-linked immunosorbent assay (ELISA) and the 2-Mercaptoethanol agglutination test (2-MAT) to detect human brucellosis patients in Korea. We examined 87 serum samples of people in the rural farm areas where bovine brucellosis had been reported. People in this study were divided into seven groups- farmers and their families, veterinarians, veterinary quarantine workers, livestock health control officers, artificial inseminators, livestock traders and healthy control individuals. Among 87 people, 65 were males and 22 were females ranging in age from 13 to 72 years. Of 87 serum samples, ELISA detected 21.84%, TAT detected 11.50% and 2-MAT detected 8.05% Brucella positive sera. Brucella specific IgG ELISA antibody titer was recorder higher in the individuals between the ages of 50 and 65 years. The highest prevalence rate of brucellosis(29.4%) was recorded in the cattle farmers and their family members followed by quarantine veterinary office workers (25%) and practicing veterinarians 01.1%). The majority of the Brucella sero-positive individuals in this study had a history of direct contact with animals.

Md. Kumrul Hassan,Faizul Wasima Nahat,Palash Kumar Bhattacharjee,Md Siddiqur Rahman,A K M Anisur Rahman,Md Ariful Islam,Mahmuda Akter Mele,채준석 한국임상수의학회 2017 한국임상수의학회지 Vol.34 No.3

A cross-sectional study was conducted to investigate the prevalence of canine influenza (CI) infection in pet dogs and canine parvovirus (CPV) infection in street dogs of different age and sex by collecting rectal and nasal swab samples from three districts, Dhaka, Mymensingh and Sirajgonj, in Bangladesh using a RapiGEN® Canine Influenza Virus Ag Test kit and RapiGEN® Canine Parvovirus Ag Test Kit. Out of 114 rectal swabs and 115 nasal swab samples, the overall prevalence of CI and CPV was found to be 11.30% and 32.45%, respectively. The prevalence of parvovirus infection was found to be significantly higher in puppies and dogs 6 months of age (50.0%) than those > 24 months of age (p = 0.005). The prevalence was also higher in males (34.42%) than females (30.18%). The prevalence of CI was higher (30.43%) in dogs up to 6 months of age (p = 0.011) than 6-12 month (7.93%) and 12-18 month (6.66%) old dogs. Moreover, the prevalence of CI was found to be higher in males (16.10%) than females (5.66%). The prevalence of CPV infection also varied significantly in different study areas (p = 0.0029), with 12.72%, 12.5% and 7.14% of dogs found to be CI positive in Dhaka, Mymensingh and Sirajgonj, respectively. Overall, the highest prevalence of CI was found in local breeds (6.08%) followed by German shepherds and Keeshonds (1.73%), and Bloodhounds and Terriers (0.86%). Additionally, there were more positive CI found in unvaccinated dogs (14.81%) than vaccinated (2.94%) dogs. Dogs with flu-like symptoms were more positive (19.23%) for CI relative to those without flu-like symptoms (4.76%) samples. Overall, the results of this study indicate that canine vaccination should be initiated to prevent the occurrence of diseases and that regular monitoring should be continued in Bangladesh.
