Published: December 2024

Background: Acute organophosphorus compound (OPC) poisoning is a serious public health issue, especially in the rural areas. Peradeniya organophosphorus poisoning (POP) scale was developed to assess the severity of OPC poisoning. Although degree of choline- esterase inhibition plays a key role in the severity of OPC poisoning, some other metabolic factors like dysglycemia also has an association. Cardiovascular effects of acute OPC poisoning are also common. Methods: This hospital based prospective observational study was conducted at indoor of Department of Medicine, Chattogram Medical College Hospital for six months period, from January 2020 to June 2020. Fifty patients above 12 years of age with acute OPC poisoning who fulfilled the selection criteria were selected consecutively for the study. After initial resuscitation severity of poisoning was assessed by POP scale, Random blood glucose (RBS) and 12 lead ECG was documented at the time of admission. Patients were followed up till their hospital stay to observe the outcome in terms of death, need for Intensive care unit support, and length of hospital stay. Results: The mean age was 33.33 (±11.73) (Range: 15-65) years. Male to female ratio was 1.77:1. As per the POP score 24% had mild, 54% had moderate and 22% had severe grade of poisoning. The mean Random blood glucose level was 186.05±51.44 mg/dl (range 90-288 mg/ dl) with 21 (42 %) cases having blood glucose value above 200 mg/ dl. ECG finding was abnormal in 56% of case with ST-T changes as the most common abnormality. Mortality rate was 24%. Most of the death occur in an average of 4th day of admission. POP score at the time of admission 7.5 or more had 91.7% sensitivity and 100% specificity to predict in hospital mortality. Admission Random blood glucose level of 207.9 mg/dl had 75% sensitivity and 68.4% specificity to predict in hospital mortality and morbidity. Conclusion: POP scale, glycemic changes and ECG are good markers for predicting morbidity and mortality and can be used as assessment tools for severity of poisoning and also to assess the prognosis of OPC poisoning cases.

An uncommon inflammatory disorder that affects the orbit of the eye is called orbital pseudotumor. It can present in a variety of clinical ways. Its precise etiology is yet unclear, although an immunemediated response is thought to be involved. A 35-year-old woman arrived to the neurology clinic with symptoms of double vision and persistent headache. There was a mild protrusion of the left eye from the orbital cavity, the eyeball medially rotated in the primary position, and restriction of leftsided eyeball movement towards the left side with complaints of increasing double vision during the attempt. She had no recent medical history or traumatic experiences. Over the course of three weeks, the initial discomfort had increased. There were no known allergies, however the patient was normotensive. Upon examination, the left eye had flare, slight anterior chamber cell, erythema, and eyelid edema. Magnetic resonance imaging showed involvement of the optic nerve, thickening of the extraocular muscles, and augmentation of orbital soft tissues. Inflammatory markers were high in the laboratory results. An orbital pseudotumor was diagnosed. The patient was treated with Inj Methylprednisolone followed by corticosteroids, her symptoms improved and the inflammatory condition subsided. A thorough approach including imaging scans, laboratory testing, and clinical evaluation is necessary for its diagnosis. The importance of recognizing an uncommon presentation and management of orbital pseudotumor with was highlighted in this case report.

Published: December 2024

The potentiality of citric acid on economy is high because of its multi-purpose uses, particularly in the food and pharmaceutical industries. Bangladesh spent more than one million US dollars to import citric acid mostly from India and China. Its consumption is increasing 3.5–4%, annually, indicating the need for better manufacturing alternatives. Globally, citric acid is primarily produced through microbial fermentation with Aspergillus niger. To support the massive scale of production of citrate, the manufacturing process must be eco-friendly which should be inexpensive and available raw materials for maintaining high yielding in a cost-effective manner. In Bangladesh prospective, the current study has undertaken to optimize citric acid production using one of the most abundant raw materials sugarcane molasses. Moreover, the aim of this study was to determine the optimum conditions to produce citric acid from sugarcane molasses using Aspergillus niger (F-81) by submerged fermentation. The amount of citric acid production was determined by the Marier-Boulet colorimetric method. The optimization data suggested that 10% substrate (from processed cane molasses), 4% inoculum size of A. niger, and initial pH 6.0 allowed to produce around 25.8 g/L citric acid. Further study is warranted to assess the feasibility of citrate production in an industrial level as well as improvement of microbial strains is needed to further enhance citric acid production.

Published: December 2024

Diabetes mellitus, a chronic metabolic disorder, has become a global health concern, prompting the exploration of alternative and sustainable sources for potential therapeutic agents. Seaweed extracts provide various benefits over synthetic medications, including lower toxicity and fewer side effects with diverse pharmacological properties, making them promising candidates for diabetes management. For this investigation, brown seaweeds, Hydroclathrus sp., were obtained from Saint Martin Island, Bangladesh. Following phytochemical analysis, the anti-diabetic efficacy of Hydroclathrus sp. was evaluated both in vitro and in vivo. In vitro studies showed that alpha-amylase inhibitory activity of 50% ethanolic extract of Hydroclathrus sp. was closely related to positive control acarbose. Besides, in vivo studies were conducted on alloxan-induced diabetes mice models, exploring the effects of Hydroclathrus sp. on blood glucose levels, and their biochemical profile was evaluated and found the algal extract at 100mg/kg body weight was more potent than the reference medicine (Glibinclamide) after 14 days of treatment. Lipid profiles and liver and kidney function tests also revealed the potent antidiabetic effects of 50% ethanolic extract of Hydroclathrus sp. These findings offer valuable information for the development of novel marine-derived anti-diabetic medications. However, further studies are required to elucidate and validate its true potential in diabetes.

Authors: Afrin Shazia , Alam Md Mahbub , Sarwar Sneha , Hossain Md Shahadoth , Sumon G M Reza , Shaheen Nazma , Amin Md Ruhul
Published: December 2024

Background/Objective: The ready-made garment (RMG) sector is key to Bangladesh's economy, significantly contributing to GDP and foreign exchange earnings. However, RMG workers, predominantly women, face critical challenges related to health, nutrition, and productivity. Despite their socio-economic importance, research on their diet quality, nutrient adequacy, and nutritional status remains limited. This study aimed to assess the dietary quality, probability of nutrient adequacy, and nutritional status of RMG workers in Bangladesh. Methodology: A cross-sectional study was conducted among 801 RMG workers (333 males and 468 females) employed in two garment industries in Dhaka and Mymensingh. Participants were selected using convenience sampling. Data on socio-demographics, dietary intake, and anthropometry were collected, and nutritional status was assessed using BMI classifications from both WHO and Asian standards. Micronutrient adequacy was evaluated using the probability approach (PA), incorporating estimated average requirement (EAR) values and standard deviations. Descriptive and inferential statistical methods were employed. Multiple logistic regression was used to investigate the influence of socioeconomic factors on workers' micronutrient adequacy. Results:  Among the 801 RMG workers studied, 58.4% were female, and 90.3% were aged 18-34. Macronutrient distribution indicated excessive carbohydrate intake (67.0% of total energy), while fat intake was often below ideal levels in 43.4% of participants (<15% of total energy). More than half of the RMG workers exhibited inadequate micronutrient intake, with a mean micronutrient adequacy (MPA) score below 0.5. The MPA of micronutrients was significantly higher for RMG workers in Mymensingh (AOR 1.68, p = 0.004) and those aged 25-34 (AOR 1.40, p = 0.049). Calcium consumption among RMG workers was alarmingly low, with most consuming less than 50% of the Estimated Average Requirement (EAR). Similarly, intakes of iron, zinc, riboflavin, and vitamin A were at or below the EAR, indicating a high risk of inadequacies. A concerning overnutrition was observed, with 44% overweight or obese based on Asian BMI standards while it was 24.1% based on WHO BMI standards, with a higher prevalence observed among female workers. Conclusion: The study findings highlight the coexistence of overnutrition and micronutrient inadequacy among RMG workers. Targeted nutritional interventions, such as establishing fair-price shops and promoting nutrition education, are recommended to improve food affordability, encourage healthier dietary practices, and enhance workforce productivity.

Published: December 2024

The elderly population in Bangladesh is rapidly growing, posing significant challenges to healthcare, nutrition, and social support systems. This study investigates the nutritional status, morbidity patterns, and food security among the elderly in Sirajganj and Chapainnawabganj districts. A cross-sectional study was conducted on 400 elderly individuals. Nutritional status was assessed using the Mini Nutritional Assessment (MNA) and Body Mass Index (BMI), while morbidity data were gathered from self-reports and medical records. Socio-demographic factors were analyzed for their association with comorbidities, nutritional status and food insecurity using multivariable logistic regression. The study found that 36% of the elderly were malnourished, and 45% were at risk of malnutrition. Musculoskeletal pain (81%), visual impairment (65.2%), hypertension (41%), and cardiovascular disease (24.7%) were the most prevalent health issues. Age, gender, marital status, income, education, no of children, and nutritional status were significant predictors of comorbidity, poor nutritional status and food insecurity. Participants aged 71 and above, females, widowed individuals, and those with lower incomes had higher odds of multiple comorbidities. The findings reveal a high burden of malnutrition and chronic diseases among the elderly in rural Bangladesh. Socioeconomic vulnerabilities and poor nutritional status contribute to health risks, underscoring the need for comprehensive interventions targeting food security, healthcare access, and disease management for the elderly population.

Characterization of sewage sludge particles influencing dewaterability
Authors: Ahmed M Feroze , Ahmed Tanvir
Published: December 2024

This study presents an investigation into the fundamental characteristics of sludge particles that influence the dewaterability of sewage sludge. Dewatering of sewage sludge is required for the reduction of sludge volume, sludge treatment, and safe disposal of sludges having very high pollution potentials. Particle characteristics important for dewatering, like particle size distribution, particle density, bound water content, surface charge, protein, and polysaccharide content of activated and digested sludges, were determined. Without a suitable method for analyzing the total range of particles in sewage sludge and effective density, new techniques have been developed to determine particle size distribution and particle density with reasonable accuracy. Particles larger than 45 μm were analyzed by wash sieving, while particles smaller than 45 μm were analyzed using a Coulter counter. The results from both methods were combined, maintaining their proportional contribution to the overall particle size distribution. Particle density was computed by determining the dry density and bound water content. Additionally, particle size and velocity were measured using an interference microscope, and these values were inserted into Stokes' Law equation to calculate the effective density of sludge particles.

Authors: Galiba Atakiya , Eshik Md Mostavi Enan , Rahman Mohammad Shamsur
Published: December 2024

Cadmium is very harmful to aquatic organisms and the environment as a toxicant. The present study investigated cadmium's morphological, behavioral, and histopathological effects on Ompokpabda. Initially, the fish were divided into 6 groups and exposed to different concentrations (20 mg/L, 40 mg/L, 80 mg/L, 160 mg/l, 320 mg/L, 400 mg/L) of CdCl2. After 96 hours of exposure, the LC50 value of CdCl2 for O. pabdawas calculated as 190.9 mg/L. Finally, based on LC50, three concentrations of CdCl2 viz., 100 mg/L, 190.9 mg/L, and 300 mg/L, respectively, with three replica and control groups were used to observe morphological, behavioral, and histopathological changes in fish. There were no abnormalities in behavior or deaths in the control group at any point in the experiment. At the same time, the behavioral abnormalities of the CdCl2-treated fish were increased as the dose increased. The behavioral abnormalities observed were loss of balance, breathing difficulty, hyperactivity, frequent surfacing, excessive mucus secretion, and gasping. After 96 hours of exposure to the final treatment, tissue samples (gill and intestine) were collected. Histopathological results revealed clear and significant alterations in the gill and intestine tissues. The alteration in the gill was characterized by hyperplasia of primary and secondary lamellae, epithelial edema, lamellar aneurism, and necrosis. In contrast, the intestine was characterized by intact serosa, less organized mucosa, a consequent fusion of mucosa, and edema between the intestinal submucosa and lamina propria. Compared with the control group, Ompokpabda of treatment groups showed severe intestinal and gill tissue injury. The result revealed that acute cadmium toxicity has a detrimental effect on the exposed fish's normal behavior and essential organs.

Effects of Varieties and Pot Colours on Boosting Capsicum Growth and Yield
Authors: Hossain Ismail , Dash Prosanta Kumar , Ray Joyanti
Published: December 2024

Heat stress can significantly hinder root growth in containerized plant production, a concern that growers often overlook. One potential solution is using different container colors to minimize the effects of sunlight on the heat balance of growing media. The current varieties of capsicum (Capsicum annuum L.) often exhibit inadequate stress tolerance, limiting capacity for boosting yield in containerized systems. This research investigated the influence of pot colour and variety selection on the growth and productivity of capsicum in a containerized system within subtropical environments. Twelve treatments were tested, including three capsicum varieties ('Intruder', 'Bomby', 'Purple Beauty') and four pot colours (red, black, white, green). Results showed that 'Purple Beauty' capsicum grown in white pots demonstrated superior vegetative growth and phenological attributes compared to those grown in black pots. Soil temperatures at a depth of 5 cm were found to be 3-4°C lower in white pots and highest in black pots. Specifically, 'Purple Beauty' grown in white pots exhibited a 27.3% increase in plant height and a 22.6% larger leaf area compared to 'Intruder' grown in black pots. Twelve weeks post-transplant, the chlorophyll index (SPAD) was 12.1% higher, and shoot and root dry weights were increased by 49.6% and 55.2%, respectively, for 'Purple Beauty' in white pots compared to 'Intruder' in black pots. Additionally, 'Purple Beauty' in white pots showed a 16.1% higher leaf relative water content (LRWC) and 29.7% less electrolyte leakage. Flowering in 'Purple Beauty' grown in white pots began six days earlier, with 25.6% higher fruit sets and 34.8% fewer flower drops compared to 'Intruder' in black pots. Marketable fruit yields for 'Purple Beauty' in white pots were 35.4% higher than those for 'Intruder' in black pots. These findings suggest that 'Purple Beauty' significantly benefits from cultivation in white pots, leading to improved plant growth, reduced heat stress, and enhanced fruit yield in a containerized production system.

Authors: Nayem Rofiqul Islam , Choity Jannatul Ferdous , Nuruzzaman Mohammad
Published: December 2024

Agricultural practices in coastal regions face significant challenges due to poor soil quality and limited nutrient availability. This study investigates the impact of maize straw biochar on the growth and yield of broccoli (Brassica oleracea) in Bangladesh's coastal region, aiming to improve crop performance while reducing dependence on conventional fertilizers. Biochar is expected to enhance soil quality by improving water retention, nutrient availability and microbial activity, making it a promising soil amendment in challenging agricultural conditions. From December 2021 to March 2022, five biochar treatments (0, 2, 4, 6 and 8 tons/ha) were utilized in the field experiment. Each treatment was duplicated three times using a Randomized Complete Block Design (RCBD). The results suggested that biochar greatly enhanced a number of growth parameters, such as leaf length, leaf breadth, dry curd weight and chlorophyll content. The highest yield (5.35 tons/ha) and primary curd weight were achieved with 8 tons/ha of biochar. However, no significant differences were observed in plant height, leaf number or primary curd diameter across treatments. These findings suggest that biochar, particularly at 8 tons/ha, is a promising soil amendment for enhancing broccoli productivity in coastal regions. Further research is recommended to explore the long-term impacts of biochar and its interactions with environmental factors and soil properties to optimize its use in agricultural systems.

Authors: Dhali Susmita , Khan Shamim Ahmed Kamal Uddin , Díaz Pérez Juan C , Kabir Md Yamin
Published: December 2024

Banana is a popular fruit that has been extensively cultivated in Bangladesh. However, high perishability along with very short shelf life of banana leads to immense fruit losses every year. An experiment was conducted to evaluate the effect of calcium chloride (CaCl₂) on the quality attributes and shelf life of bananas cv. Jin. The experiment was laid out in a completely randomized design with four treatments (3%, 5%, and 9% CaCl₂ concentrations and an untreated control) and three replications. The fingers of bananas were separated; randomly divided into four groups (10 fruits per group), and wetted with the CaCl₂ solution through spraying. The 5% CaCl2 treatment resulted in decreased cumulative fruit weight loss (17.85%), disease severity (50%), disease incidence (70%), and extended shelf life (5.33 days) compared to the untreated control. Banana fruit treated with 5% CaCl2 also delayed color development and maintained fruit quality (TSS, vitamin C). Therefore, a 5% CaCl2 application could be recommended for extending fruit shelf life and decreasing the decay and water loss of bananas.

Published: December 2024

Rail quality decreases directly in proportion to the operating time of the train since the rail is loaded from the train wheels. Railroad tracks are inspected by PPJ (Track Inspector) by using a track gauge master to measure slope. Manually operated devices cause PPJ to run along the railroad between stations, causing accidents and requiring relatively long operating times. Using a device that measures the slope of railroad tracks is a more effective solution to these problems. The device uses a gyroscope sensor and GPS module to locate non-standard rails. A complementary filter is applied to the converted pitch and roll values. A slope measuring instrument was used to test the accuracy of pitch and roll angles. Gyroscope sensors are calibrated to prevent measurement errors (errors). Based on the results, the gyroscope sensor had an accuracy error of 0.20Â° in pitch and 0.27Â° in a roll. A complementary filter reduces error accuracy to 0.06Â° for pitch and 0.08Â° for roll. Its accuracy compared to smartphone GPS is 5.38 meters, while its accuracy compared to the actual location is 7.74 meters.

Taroi District is one of the districts in Teluk Bintuni Regency which is also known as a shrimp producer. Therefore, almost all the people of Taroi District work as fishermen. Shrimp production is greatly influenced by climatic factors so that there is a shrimp fishing season. In the non-shrimp fishing period, the community experienced difficulties in maintaining stable economic conditions. Coconut trees grow abundantly in the Taroi District area, from the coast to the mainland. However, the utilization of coconut commodities can be said to be very low. The main obstacle in developing coconut commodities is limited market access. The geographical location of Taroi District which is far from the district capital causes high transportation prices so that people are unable to market coconuts. Several strategies that can be used to overcome these obstacles are by 1) improving the quality of fruit through the creation of coconut plantations in dry areas, 2) variations in processed coconut products (virgin coconut oil, coconut oil, nata de coco, coconut honey, charcoal briquettes and cocopeat) and 3) availability of transportation and market access.Keywords: Coconut, Taroi District, Teluk Bintuni Regency

This paper introduces typical Grid-Forming (GFM) technologies in power grids, including steady-state and fault current limiting strategies, studies the equivalent structures of steady-state and fault traversal under GFM technology, analyses electrical characteristics under different fault types from the voltage plane, and illustrates the differences from traditional synchronous systems. This paper analyses the phase current differential protection, zero sequence current differential protection, and positive sequence voltage polarisation distance protection applied in traditional power grids, and clarifies their action behaviour under the GFM system. The analysis shows that the GFM technology creates a relatively good operating environment for relay protection by simulating the basic characteristics of synchronous generators, which is conducive to improving the operational performance of relay protection.

Technological advancements have transformed various sectors, including the financial system, presenting competitive challenges for Sharia Rural Banks (BPRS) that still rely on manual operations. To address this, BPRS must focus on factors influencing customer decisions to enhance their activities. This study investigates the impact of margin levels and service quality on murabahah financing decisions at the Al-Salaam Amal Salman BPRS Cileungsi branch. A quantitative associative approach was employed, involving 60 murabahah financing customers as respondents. Data was collected through questionnaires and analyzed using SPSS 21 with validity, reliability, multiple regression, and classical assumption tests (normality, multicollinearity, heteroscedasticity, autocorrelation), alongside hypothesis testing (coefficient of determination, F-test, and t-test). The results reveal that the margin level and service quality significantly influence customer decisions, with an R-squared value of 87.1%, indicating 87.1% of decisions are explained by these variables, while 11.9% are influenced by other factors. The F-test showed a significance value of 0.000 < 0.05 and F-statistic of 191.657 > 3.16, confirming a simultaneous effect. The t-test demonstrated significant individual effects of margin level (p = 0.006, t = 2.830 > 2.002) and service quality (p = 0.000, t = 13.764 > 2.002). Improved margins and service quality increase customer decisions and attract new customers.

TRANSFORMASI PROSES KREASI MAHASISWA FSRD DARI KONVENSIONAL KE DIGITAL (STUDI KASUS: RUPA DASAR DUA DIMENSI)
Authors: Ayuningtyas Niken Larasati , Sari Nedina
Published: December 2024

Rupa Dasar Dua Dimensi I (RD2D I) merupakan mata kuliah dasar dalam kurikulum Tahap Persiapan Bersama (TPB) pada Fakultas Seni Rupa dan Desain (FSRD) di Institut Teknologi Bandung (ITB). Tujuan kurikulum mata kuliah ini untuk memperkenalkan dasar kesenirupaan melalui proses kreasi untuk melatih keterampilan tangan, memberi pemahaman, dan mengasah kreativitas dalam mengolah unsur dan prinsip visual. Awalnya proses kreasi dilakukan dengan cara konvensional, namun dalam beberapa tahun terakhir terjadi pergeseran menggunakan media digital. Pergeseran ini memunculkan gap antara kompetensi yang diasah melalui cara konvensional dan digital. Penelitian ini bertujuan menganalisis transformasi tersebut dengan fokus pada gap antara cara konvensional dan digital serta menganalisis tren penggunaan media digital pada RD2D I. Melalui kombinasi metode observasi partisipatoris, wawancara, dan kuesioner, penelitian ini mengeksplorasi sejauh mana mahasiswa mengadopsi media digital, kapan pergeseran cara ini terjadi, dan apa alasan di balik preferensi mereka memilih cara digital. Hasilnya, sebagian besar mahasiswa telah beralih ke penggunaan media digital karena proses kreasi membuat tugas RD2D I menjadi lebih mudah, praktis, dan cepat. Meskipun begitu, cara konvensional memberikan pengalaman estetika yang lebih intens. Potensi riset ke depannya dapat mengeksplorasi integrasi cara digital dan konvensional dalam berbagai mata kuliah praktik lainnya, sekaligus mengevaluasi cara terbaik untuk mempertahankan kualitas pembelajaran.
