Authors: Ahmed Md Sultan , Begum Afroza , Hossain Prodhan Mohammad Dalower , Sarker Debasish 
Published: September 2021

The study was conducted to analyze the amount of residue of six commonly used pesticides (e.g. chlorpyriphos, quinalphos, diazinon, acephate, dimethoate and fenitrothion) in vegetables viz., hyacinth bean and eggplant samples collected from local market of nine different locations viz. Cumilla, Bogura, Rangpur, Rajshahi, Khagrachari, Cox’s bazaar, Barishal, Jamalpur and Dhaka for the comparison between the detected residue level with maximum residue limit (MRL) set by European Union. Among 36 analyzed samples of hyacinth bean six samples (16.67%) were contaminated with chlorpyriphos (0.082 mg/kg) and dimethoate residue (0.192 mg/kg - 0.961 mg/kg), all of them were above maximum residue limit. Out of 36 analyzed samples of eggplant 3 samples (8.33%) were contaminated with quinalphos (0.081mg/kg) and dimethoate residue (0.032 mg/kg - 0.217 mg/kg) which were above MRL. Most of the samples contained with dimethoate residue in both the vegetables. The presence of pesticide residue exceeding MRL in vegetables is harmful to human and other living organisms. Analyzed samples of Cumilla, Bogura, Rangpur and Rajshahi showed pesticide residue (i.e. dimethoate, chlorpyriphos and quinalphos) over MRL but the samples of other five locations like Cox’s bazar, Khagrachari, Barishal, Jamalpur and Dhaka did not show any detectable residue which might safe for consumption.

Published: September 2021

Use of fish toxicants is an important management tool in inland commercial aquaculture. In entrepreneurial fishery in northwest Bangladesh where pond ownership (using rights due to lease) changes frequently (every few years) use of fish toxicants is very routine and more crucial. Along with some traditional fish toxicants (rotenone and aluminium phosphide), unconventional and insecticides like fenpropathrin (not approved for aquaculture use) are being used by fish farm owners in northwest Bangladesh. The study was conducted to understand the consequences of use of fenpropathrin compared to other traditional fish toxicants in commercial aquaculture for harvesting of food fish. Of all the toxicants, fenpropathrin’ s impact was lowest on zooplankton and aquatic insect population, while rotenone had the lowest impact on benthos population in terms of killing and quick recovery time for the population, primarily due to the high turbidity (suspended soil particle) of the pond water (under this study) by which both fenpropathrin and rotenone got affected. Aluminium phosphide found to be more damaging in terms of killing and relatively longer recovery time for zooplankton, aquatic insect and benthos population. Using convenience, quick killing, cheaper price, short duration of toxicity and no potential long-term damage of the waterbody contributes positively for fenpropathrin as fish toxicant except the severe potential public health concern from eating of fish killed by fenpropathrin due to very high bioconcentration factor of fenpropathrin; hence, demands regulation of fenpropathrin’ s use as fish toxicants for food fish.

Published: September 2021

Indiscriminate use of antibiotics in broiler could lead to residue accumulation in food chain. We conducted a study to detect colistin residues in broiler meat in different growth stages, collected from different upazilas of Mymensingh division. A total of 108 samples, were collected from Fulbaria, Mymensingh Sadar, and Trishal Upazila of Mymensingh district and Nakla Upazila of Sherpur district. From each farm, nine samples were collected at the three different growth stages: 14-20 days (Early:E), 21-27 (Middle:M) days and 28-35 (Late:L) days, respectively. Thin layer chromatography (TLC) was used for the qualitative detection colistin residues in broiler meat. A questionnaire survey was carried out with the farmers from whom the samples were collected. Most of the farmers’ had varying degree of knowledge about biosecurity, withdrawal period and residue of antibiotic, and academic qualification varies from primary to graduate level. Out of 108 samples, 50% (18 out of 36) samples were positive for TLC in early samples, whereas 66.67% (24 out of 36) samples for middle and 50% (18 out of 36) for late collected samples. Upazila-wise, the highest concentration was detected in Mymensingh sadar and Nakla (66.67%) and lowest in Fulbaria (33.33%). These result indicates that colistin are being misused in poultry industry especially in middle days of broiler life and withdrawal periods are not maintained when broiler are marketed. Being a Reserve group antibiotics, measures are needed to ensure human safety regarding colistin residue in poultry industry.

Authors: Hiya Hafsa Jahan , Parvej Md Suman , Farukh Murad Ahmed 
Published: September 2021

In a subsistence agrarian economy of Bangladesh, domestic food production has an important role to play in the quest for food security. The productivity in the agricultural sector is critically important if agricultural production is to increase at a sufficiently rapid rate to meet escalating demands for food. Bangladesh has pursued for decades a strategic goal of self-sufficiency in rice production. The country passed a major milestone in its efforts to achieve food security in the sense of rice grain availability at the national level at the end of the 1990s. Whatever progress been made would be difficult to sustain it due to high vulnerability of climatic shocks and the growing pressure of population on scarce natural resources thus, yet food security has not been achieved. The present study finds that, rice production is secure in Feni district from Chittagong division. Because rice production is greater than the consumption. On the other hand, Chandpur and Cox’s Bazar district shows production insecurity in the very recent years. But Chittagong district has the production insufficiency from the past to present, because the production is insufficient to meet the demand of the vast population in this area. The study reveals that, the production of Aus rice will be increased in the next 5 years in Chittagong district. Aman rice production will be increased in the next 5 years in the districts namely Feni. Again, Boro rice production will be increased in the next 5 years in the districts namely Cox’s bazar and Feni districts.

Published: September 2021

The present study is an attempt to assess the impact of SSS (Society for Social Service) credit on women beneficiaries of Gouripur upazila at Mymensingh district in Bangladesh. The study revealed that both annual income and expenditure of the respondent households have increased after joining the micro credit program of SSS. Average family size of agriculture and petty business enterprises were 4.69 and 4.21. Average annual income of agriculture and petty business enterprises were Tk 80726.57 and 74864.14 respectively while average annual expenditure of agriculture and petty business enterprises were Tk 78776.65 and 67912.37 respectively. It was evident in the case of children education (60.00 percent), labor employment (40.00 percent), crop production (55.00 percent), taking care of children (30.00 percent) and rearing poultry birds. The highest (66.67 percent) proportion of the respondents reported insufficiency of credit supply was a moderate problem and only 33.33 percent of them reported this not at all a problem to them. The interest rate charged by the SSS as a major problem, 36.67 percent of the respondents opined as high. About 48.49 percent of the respondents reported that burden of old debt was not at all a problem while 1.67 percent said that it was a great problem to continue their existing activities. The finding shows that SSS credit program encouraged the women beneficiaries to participate in the social development activities in the study area.

Authors: Islam M Rafiqul , Kabir SM Lutful , Islam Md Serazul 
Published: September 2021

The study was designed to explore the women’s empowerment through small-scale dairy farming in Bangladesh. Small-scale dairy farm owners constituted the population of the present study. Among the population, the households who were actively engaged in dairy farming activities more than one year in the selected area of Mymensingh district, they were considered as the sample unit. For data collection, 50 households from the sample unit were randomly selected for interview. Simple percentages were calculated to show the frequency distribution at different categories of variables. Through small-scale dairy farming, rural women were able to increase their confidence and decision-making power with regard to their household and personal care and experienced increased self-esteem, expansion of their social circles, and ultimately enhanced empowerment through the breakdown of traditional socio-cultural norms. Thus, the expansion of small-scale dairy farming in other rural areas of Bangladesh is likely to contribute to the empowerment of more rural women.

The present experiment was conducted in order to investigate the use of agrochemicals in freshwater aquaculture with emphasis on fish health management. The selected area was Mahespur upazila under Jhenaidah district and the study duration was six months. The main group was fifty fish farmers and the data were collected through interview with fish farmers and key informants (chemical seller). Ten categories of chemicals were identified that are used by fish farmers for various purposes such as pond preparation, water quality management, controlling diseases, supplying oxygen, killing fish predators, Ten pharmaceutical companies were found to provide the agrochemicals to fulfill the farmers need. These companies are Novartis Anmal Health Ltd, Fishtech (BD) Ltd, SK+F BD Ltd, Renata Ltd, ACI Animal Health, Opsonin Pharma Ltd, Eon Animal Health Products Ltd, Square Pharmaceuticals Ltd, Sciencetech Agro Industries Ltd, Rals. In the study area some kinds of diseases were founded such as Epizotic Ulcerative Syndrome (EUS) in Rohu (Labeo rohita), Catla (Catla catla), Mozambique tilapia (Oreochromis niloticus), Black spot in Stinging cat fish, skin diseases, gill damage, tail and fin rot in Yellow tail catfish (Pangasius pangasius). For highest stocking density tilapia and pangus were mostly affected by diseases in winter. Farmers use various chemicals such as for water quality management agriculture lime, Geotox, JV Zeolite, Mega Zeo Bio, Aquakleen and Biomin, as antibiotic they use Novamix 101, Erocot, Captor, Oxysentin 20%, Renamycin, Aquamycin and Oxysentin 20% are antibiotics with different trade names were seen in the market as well as used by the fish farmers in the study area. The fish farmers use a wide variety of disinfectants in freshwater aquaculture. Timsen, Polgard plus, Formalin, Bleaching powder, EDTA are found available in all the shops of Mahespur. Formalin is used to control protozoan diseases. Virex is used to destroy virus and bacteria. Fish farmers use oxygen suppliers to increase the oxygen level in the water body. Oxidizing agent, hydrogen peroxide are major active ingredients of such chemical. The recovery of fish diseases was found 80-90% in the study area. During field observation many problems were identified in case of using agrochemicals which included lack of skill and knowledge of farmers about the application, withdrawal period of agrochemicals and drugs and some adverse effects on fish and human health.

Study on Flow Behavior of Parallel Lumped-Model under Constant Flow for Bronchial Tree
Authors: Ahmmed MU , Sultanab M 
Published: September 2021

Redistribution of flow in the bronchial tree is an important factor that enhances gas exchange in the lungs, especially, in diseased lungs. The bifurcated bronchial tree is like an electric network in series and parallel. A lumped-model of parallel system for constant flow rate is solved analytically to demonstrate the intrinsic characteristics and the dynamic behavior of the system. Inertial and capacitive time constants are calculated for 19th generation airways of human lung to control the solution. The investigation revealed that (i) higher inertial force takes more time to maximize the inertial flow to steady state and more time to minimize the resistive flow to steady state and (ii) the compliant effect is negligible for a relatively higher inertial time constant, on the same experimental conditions.

Authors: Rosa Henrique Marcio Pereira , Toledo Gabriela Pereira 
Published: September 2021

Computational fluid dynamics (CFD) is the most current technology in the fluid flow study. Experimental methods for predicting the turbomachinery performance involve greater time consumption and financial resources compared to the CFD approach. The purpose of this article is to present the analysis of CFD simulation results in a centrifugal fan. The impeller was calculated using the one-dimensional theory and the volute the principle of constant angular momentum. The ANSYS-CFX software was used for the simulation. The turbulence model adopted was the SST. The simulation provided the characteristic curves, the pressure and velocity distribution, and the static and total pressure values at impeller and volute exit. An analysis of the behavior of the pressure plots, and the loss and recovery of pressure in the volute was performed. The results indicated the characteristic curves, the pressure and velocity distribution were consistent with the turbomachinery theory. The pressure values showed the static pressure at volute exit was smaller than impeller exit for some flow rate. It caused the pressure recovery coefficient negative. This work indicated to be possible design a centrifugal fan applying the one-dimensional theory and optimize it with the CFD tool.

Analisar os padrões e comportamentos alimentares em crianças portadoras do Transtorno do Espectro Autista (TEA). Trata-se de uma revisão integrativa da literatura. A busca dos artigos foi realizada nas bases de dados da BVS, Scielo, Lilacs, PubMED e Google Acadêmico entre os períodos de agosto de 2020 a junho de 2021. Foram encontrados 62 artigos e somente 11 foram selecionados para a discussão dos resultados. Os descritores utilizados foram: “Padrões Alimentares”, “Comportamento Alimentar”, e “Transtorno do Espectro Autista”. Os critérios de inclusão foram artigos originais, indexados nas bases de dados selecionadas, nos idiomas: português e inglês; publicado entre os anos de 2011 e 2021. Os critérios de exclusão foram publicações de teses, anais de congressos, dissertações, monografias e artigos que não tinham aderência à temática. Quanto aos padrões alimentares as crianças preferem alimentos de alta densidade energética como as bebidas açucaradas e comidas crocantes, e apresentam um baixo consumo de frutas, vegetais, peixes e laticínios. Quanto aos comportamentos identificou-se uma grande recusa alimentar e relutância em comer novos alimentos como frutas, vegetais, peixes e laticínios, além de comportamentos problemáticos como resistência para sentar-se à mesa e comer com outras pessoas, entrar no refeitório e não ficarem sentados à mesa até a refeição acabar, e em aceitarem novas preparações, além disso ficou evidente que o comportamento dos pais influencia diretamente na seletividade alimentar e em suas escolhas. O acompanhamento dos pais de crianças com TEA trarão resultados positivos no entendimento desses padrões e comportamentos alimentares dessas crianças, para contribuir com os profissionais da área.
