Nowadays, researchers have found many applications of biochar due to its large surface area, ion and water holding capacity, sheltering possibility for microbes beneficial for the plants’ nutrition intake, carbon sequestration etc. Among several waste biomass feedstock, agricultural waste is a suitable source of biomass for the biochar production. So, in this study, a low cost, modular technology was proposed that can be used at the consumer end to produce biochar of satisfactory quality. In this technology, no separate inert gas feed was required, thereby lowering the cost and complexity of the system. The reactor was designed in a way that most of the oxygen got consumed at the beginning of the process and the residual nitrogen from air maintained a pseudo-inert environment. As potential feedstock for biochar, rice husk and wood chips were considered in this study. Also, to evaluate the quality of produced biochar, proximate analysis and calorific value were measured. The char yields were found to be between 20 to 40%. For rice husk (powdered and granular) and wood chips, the volatile content (%) were 15.88, 19.69 and 25.47 respectively meaning most of the volatiles were released during devolatilization. It was found that biochar can be produced from agricultural waste using this method by farmers in the field without any additional equipment, and the pyrolyzer is modular and portable. Finally, the biochar could be used for soil replenishment. Further work is ongoing on the char characterization to realize the full potential of biochar production from waste biomass.

The study describes traditional fishing gears and crafts available at Gumti river of Muradnagarupazila in Cumilla district, Bangladesh. The study was carried out by the collection of primary data through surveying individual fishermen. We found that there are 6 fishing gears available in the study area. Among them, 5 types of the fishing net (i.e., cast nets, seine net, lift net, push net, gill net) and a kind of fishing trap was identified. We also found 4 different types of crafts, including dinginauka, koshanauka, chandinauka, and sototempu. Synthetic twines are used for net making, which increases the fishing efficiency significantly. The life span of these nets varies according to their building materials. Sun-drying was the best approach for net preservation rather than using any chemicals or medicine. Besides, traditionally mehogany, raintree, shill koroi, garjan, gamari, jarul, chapulis woods and bamboos were found to be boat construction materials. The boats are painted with tar or pitch and burn oil for the protection. No modern instruments such as a compass, life-saving equipment are used by these boats. Most of the boats are mechanized, i.e. operated by engine. Asian J. Med. Biol. Res. September 2020, 6(3): 469-474

Cholesterol granuloma is a rare benign tumour and is described as inflammatory granulation that occurs in response to the deposition of cholesterol crystals. It is found most commonly in the paranasal sinuses or temporal bones, but there are also rare reports of their occurrence in the peritoneum, parotid gland, lymph nodes, thyroglossal duct, kidney, liver, and spleen. Involvement of the ribs has rarely been described previously. We report a case of cholesterol granuloma involving chest wall in second intercostals space of a 74-year-old male who presented with a slowly growing lesion of the anterior aspect of right side of the chest.

Purpose: In order to achieve the Sustainable Development Goal (SDG) 3 target of reduction in under-five mortality below 25 per thousand live birth by the year of 2030, major reductions are going to be required in neonatal mortality. Congenital anomalies have become the fourth cause of neonatal deaths and most of these are curable. The largest public hospital of Bangladesh is serving the poor and lower middle class people where surgery and medical facilities are mostly free of cost. This study was done to see the types of neonatal surgical patients admitted in this hospital and their management out come with limited facilities and find out some new ideas and information and the ways to improve the scenario to contribute in achieving the SDG 3. Materials & Methods: This was a descriptive study with retrospective record review of all admitted neonates done over a period of 17 years from July 2001 to June 2018 and carried out in the Department of Pediatric Surgery. A total of 2492 neonates were admitted during this period and it was the 16.16% of total number of 15414 pediatric surgical admission upto12 years of age. Data was collected from hospital records and analyzed retrospectively. Detail history of each patient was collected and recorded in a pre-designed, semi-structured questionnaire. Statistical assessments were done by SPSS version 22. An Ethical clearance had been sought. Results: Out of these 2492 neonates, 1932 (77.53%) were admitted for Neonatal Intestinal Obstruction (NIO) and Intestinal atresia 246 (09.87%), Omphalocele 163 (06.54%), Meconium ileus 154 (06.18%), Volvulous neonatoram 125 (05.02%), Septicemia 114 (04.57%), Posterior urethral valve 78 (03.13%), Gastroschisis 75 (03.01%), Abscess 57 (02.29%), Congenital Diaphragmatic Hernia 54 (02.17%), Ectopia vesicae 50 (02.01%), Infantile pyloric stenosis 42 (01.68%), Tracheo-oesophageal fistula 24 (0.96%), Prune belly syndrome 8 (0.32%), Neonatal injury 5 (0.20%), Conjoint twin 4 (0.16%). The most common cause of NIO was anorectal malformation (ARM) 806 (32.34%). Among them 516 (64.02%) patients had high variety and 290 (35.98%) patients had low variety ARM. Next was Hirschsprungs disease and 487 (19.54%) neonates presented with this. One hundred and forteen (4.57%) patients presented with septicemia and 246 (9.87%) presented with intestinal atresia, 154 (6.18%) neonates had meconium ileus and 125 (5.02%) patients presented with volvulus neonatorum. Total 1791 (71.86%) patients were managed surgically. Most of the surgerical procedures were pelvic colostomy 541 (21.71%), transverse colostomy and biopsies 376 (15.09%), resection and anastomosis 261(10.47%), anoplasty 239 (9.59%), primary repair 135 (5.42%) and ileostomy 104(4.17%). Out of 2492 patients, 351 died, so mortality was 14.09%, before surgery 127 (5.10%) and after surgery was 224 (14.85%). Conclusion: Pediatric surgeons by their skill and teamwork greatly improved the neonatal surgical service and contributing significantly in reducing infant mortality rate to achieve SDG 3. But to improve further, neonatal intensive care unit (NICU) and other support systems are essential as well as support from UNICEF and World Health Organization (WHO) to include pediatric surgery and surgeons in their activities especially in developing countries. Due to socio-political and economic reasons of the developing countries the roll of pediatric surgeons are multidimensional. Bangladesh Med Res Counc Bull 2020; 46(1): 05-11

The study was conducted to determine growth performances and bioaccumulation of Cr, Cu, Cd, Pb and Ni in fish organs such as intestines, muscle and gills of study species after culturing them for twelve weeks by using different commercial fish feeds. The highest average daily gain (ADG, g/day) and specific growth rate (SGR; %/day) were found in fish fed quality feed and lowest values were found in the fish fed mega feed. Best feed conversion ratio (FCR) value was found in fish fed quality feed among five different feeds. In cultured Koi, the concentration of heavy metals were found higher than initial concentration in fish feeds and collected fingerling samples. Heavy metal levels in cultured fish was Cu > Pb > Cr > Cd > Ni and levels of bioaccumulation in individual organs was intestines > gills > muscle. The concentration of Cu, Pb and Cr exceed the tolerable limit approved by FAO in fishes cultured with the experimental feeds. Considering the present study, Koi cultured with these experimental feeds may not safe for human consumption. Bangladesh J. Zool. 47(1): 77-88, 2019

The present study was designed with a view to study the effects of enrofloxacin antibiotic on ISA brown layer performance. A total of 1,80,000 laying hens (ISA brown) received and supplied enrofloxacin antibiotic in the dose of 0 mg, 10mg and 20 mg/kg BW with normal diet. Each layer was fed 120 g feed/day from 42 to 48 weeks of age. Antibiotic made significant differences in egg production (p

Background: Laparoscopic surgery for acute appendicitis in children has been proposed to have advantages over conventional surgery. Introduction: Appendicitis is the most common surgical emergency in childhood. 1 For decades, Open appendectomy (OA) has been the standard treatment for all forms of appendicitis with excellent results. 2 Since its description in the early 1980s, laparoscopic appendectomy (LA) became an acceptable approach for simple appendicitis in children. 3, 4, 5 However, its role in the treatment of complicated appendicitis is controversial. Today, in developed countries about 8% of the population is appendectomized for acute appendicitis during their lifetime. 7 Materials and method : We are conducting a prospective comparative study with the intention to observe the outcome of 60 purposively selected patients of acute appendicitis in the Department of Pediatric Surgery, Dhaka Medical College & Hospital (DMCH), Dhaka, over a period of 12 months from October, 2013 to October, 2014. The patients are going to be divided into 2 groups by random sampling- Group A- OA Group (patients underwent open appendectomy) and Group B- LA Group (patients underwent laparoscopic appendectomy) for uncomplicated appendicitis. Children up to 14 years are planned to be selected as study subjects. All children are subjected to investigate for white blood cell (WBC) count, plain X- ray KUB region, urine R/E, preoperatively and to observe the amount of analgesics in postoperative pain management and cosmesis on first week, first month, and third month of operation. Structured questionnaire is used to collect information regarding pain, fever, other association preoperatively and operative procedure, duration of operation, per operative findings and post operative follow up. Informed written consent from parents or legal guardian is taken after describing the study objectives. Ethical clearance has been sought from the Ethical Committee of Dhaka Medical College. Results: Total 23 patients are studied till now, 16 in LA group and 7 in OA group. From this limited data we have seen that there is apparently minimum difference between two groups of study population regarding postoperative outcomes. Conclusion: This is an on-going study. Definite conclusion could not be drawn at this preliminary stage. Laparoscopic appendectomy for uncomplicated appendicitis in children is feasible and safe. It is associated with a significantly less use of post operative pain killer, lower incidence of wound infection, and reduced length of hospital stay when compared with patients who had open appendectomy.

Background: ACL injuries, is a serious problem in sports. Treatment of ACL injury is costly and it often takes 12 months or more to return to sports or in worst case and lead to early retirement. The long term outcome is also concerning issue. Objective: The goal of this study was to identify the nutritional status and causes of injury in relation with exercise habit among the patients with anterior cruciate ligament injury.Methods: A cross-sectional descriptive study was carried out in a super specialty modern tertiary care level hospital in Dhaka, Bangladesh. Total 63 samples were collected purposively to conduct this study. Data were collected through face to face interview by pretested semi-structured questionnaire and anthropometry was measured by standard technique. Prior data collection written consent was taken from the respondents. Descriptive as well as inferential statistics were used for data analysis.Results: The mean age (±SD) of the respondents was 27.52 (±7.59) years where 95.3% were male patients and 4.7% were female patients. Regarding their nutritional status, 23.8%, 55.6% and 20.6% were normal, over weight and obese respectively. Moreover 61.9% respondents had regular exercise habit whereas 38.1% respondents had no regular exercise habit. Besides there was no significant association (p>0.05) found between causes of injury and types of injury with exercise habit.Conclusion: Most of the patients were over nourished and no significant association was found between vehicle used and causes of injury. Further large scale study is needed to get actual picture.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i3.21026

This study focused on the generation of electricity from whey in a bio-fuel cell (BFC). Whey or Milk Serum is the liquid remaining after milk has been curdled and strained. It is a by-product of the manufacture of cheese or casein in Foods and Sweets Company. It was selected as electrolyte in biofuel cell due to containing higher amount of branched-chain amino acids (BCAA's).The pH value of fresh whey was 3.1-3.8. Three categories of whey were used in the experiments included fresh whey, preserved by thermal treatment and preserved with 2% phenol by volume. It was observed that microorganism growth was zero in the sample with 2% phenol and growth rate was medium in the sample preserved by thermal treatment and that was higher in the fresh sample. In this biofuel cell, voltage was increased with the increase of surface area of electrodes. For a single compartment containing 8 unit cells, resultant voltage and current were 2.86V and 450?A and four compartment 32 unit cells in series, the values were 10.90V and 8.05mA respectively. When anode area was increased to reduce polarization, power generation was initially high but the decreasing rate of power was also elevated. Finally, for commercial electrodes, maximum power and minimum internal resistance were recorded. The maximum Current, Voltage and Power for commercial electrodes in a single compartment containing 10 unit cells were 78mA, 3.88V and 0.30264W respectively.
