In this study, bread was fortified with roasted cowpea flour (RCF) in varied amounts (0-20%). The chemical compositions and sensory properties of RCF-supplemented bread samples were evaluated using conventional procedures. Proximate analysis results demonstrated that RCF addition greatly raised the crude fiber (1.78-2.32%), ash (3.08-3.46%), fat (4.58-5.35%), and crude protein (13.81-16.82%) of the bread samples, while carbohydrate content (71.3-66.84%) reduced significantly. Supplementing bread with RCF increased the mineral content (calcium, iron, phosphorus, and magnesium) of the final bread samples. The sensory assessment score demonstrated differences in general acceptability between sample B (5% RCF with 95% wheat flour) and the other bread samples. Thus, supplementing white bread with RCF resulted in bread with improved nutritional content, particularly protein, magnesium, and phosphorous, which are required for good health.\u0000Bangladesh J.

Here, reinforcing materials came from discarded coir doormats and jute sacks. The waste fibre was treated with NaOH and then embedded into the polyester matrix using a cold compression moulding technique. On the other hand, talc filler and waste-fibres reinforced polyester resin hybrid composite was developed using the same technique, and a comparative study was performed. WF/PE hybrid composite showed tensile and flexural strength of 36.67 MPa and 38.76 MPa respectively. Talc filler-filled T/WF/PE hybrid composite reported 23.95 MPa of tensile strength and 65.2 MPa of flexural strength. Average Leeb’s robust hardness (LRH) was found 495.667 and 524.75 for WF/PE and T/WF/PE respectively. T/WF/PE hybrid composite presented low-temperature thermal degradation compared to WNF/PE hybrid composite. Surface morphology studies showed that coagulation of fibres, voids, and fibre pullout at the inner interface of the composite was a common phenomenon for both composites. WF/PE composite showed higher electrical resistivity to applied voltage compared to T/WF/PE. Water absorption studies showed that talc filler boosted the water adsorption of the T/WF/PE hybrid composite.\u0000Bangladesh J. Sci. Ind.

Food security is a critical concern in Sri Lanka, influenced by factors such as climate change, agricultural practices, and societal dynamics. Leveraging their capabilities and resources, the Sri Lanka Army can significantly contribute to addressing these challenges. This study examines the potential contributions of the army in terms of food production, infrastructure development, technology adoption, and capacity building and development. Research design is a mixed-methods approach were used by a structured questionnaire targeting various stakeholders, including pertinent Sri Lanka Army personnel and conducted in-depth interviews with key stakeholders. The analysis underscores the importance of collaboration, knowledge transfer, and sustainable practices in achieving lasting food security. Through a comprehensive approach and collaborative efforts involving various stakeholders, including government bodies, local communities, and agricultural organizations, a more resilient and secure food system can be envisioned for Sri Lanka.\u0000Bangladesh J.

These metals can pollute water, and soil and also come in contact with the food chain, causing life-threatening health issues in the human body. The pore volume and the specific surface area of the brick sand particles were determined using the standard method which was 44.41% and 29.4 m2/g respectively. The different concentrations of toxic metals in the water solution were considered to determine the adsorption capacity of the adsorbent. The adsorption methods were able to remove about 94% of Cr, 24% Pb, and 69% Fe from the aqueous solution. From the investigation results, we may conclude that raw brick sand particles can play a vital role as an adsorbent in the treatment of heavy metal-contaminated wastewater. Moreover, the saturated adsorbent can be used as an element of construction materials to prevent further pollution.\u0000Bangladesh J. Sci. Ind.

Geochemical analysis coupled with petrographic studies indicates the BIF and BIF-hosted rocks were derived from sedimentary protoliths.

Monazite chemistry U-Th-Pb geochronological evidence indicates the deposit was affected by a single, medium-grade metamorphic event that occurred at 1728±28 Ma during the Basement rock’s magmatic event activated.

The solid dispersion formulations (SDF) were made through physical mixing, solvent evaporation, and melt solvent/fusion. Using three ratios of IVM and hydrophilic carriers (1:1, 1:2, and 1:3), the cumulative release rate of IVM from formulations formed by physical mixing, solvent evaporation, and fusing was much larger than pure IVM (10%). IVM release rates from formulations including Poloxamer 407, Kollicoat IR, and HPMC polymers were 76% (fusion technique), 69% (physical mixing), and 47% (solvent evaporation method).
