Physicochemical and nutritional quality of five improved cultivars of desi and kabuli chickpeas and their products were studied. The kabuli chickpea had larger seed (26 g/100 seeds) than desi type (21 g/100 seeds). The hydration capacity per seed of desi (0.16 g) was lower than kabuli type (0.26 g). A positive correlation (r = 0.87) between seed weight and hydration capacity was observed. The mean cooking time of dry desi vs kabuli seed (124.5 vs 113.8 min) was reduced to 37.5 vs 32.8 min and to 28.8 vs 22.5 min when soaked overnight in water and in 0.5% solution of sodium bicarbonate respectively. The mean value of protein (25.4 vs 24.4%), fat (3.7 vs 5.1%), carbohydrate (47.4 vs 55%), crude fibre (11.2 vs 3.9%), ash (3.2 vs 2.8%) and caloric value (327 vs 365 kcal/100 g) were for desi vs kabuli chickpeas respectively. There was no difference in the essential amino acid contents and in chemical scores of desi (65) and kabuli (67) chickpeas. The order of limiting amino acid was methionine+cystine, threonine and valine in both types. The chickpeas products contained 8.9-21.1% protein (N x 6.25), 3.1-21.8% fat, 53.4-75.9% carbohydrate, 1.6-11.1% crude fibre, 1.2-5.9% ash, 226-360mg Ca, 126-315 mg P, 3.8-8.2 mg Fe, 1.8-5.4 mg Zn, 1.5-5.4 mg Mn, 0.6-1.1 mg Cu and 370-490 kcal per 100 g. All chickpea products provided 7-23%, 7-40% and 52-78% of the total calories from protein, fat and carbohydrates respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Tannery wastewater contains large amount of chemical compounds including toxic substances. So an attempt was made to characterize physiochemical parameters of tannery wastewater and investigate the efficacy, and applicability of the biological treatment utilizing aquatic plants macrophytes and algae. Total suspended solids TSS and total Dissolved solid in the original wastewater were found 1250 mg/l and 21300 mg/l respectively. The pH and temperature were 8.3 and 29°C. Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) were 2.72 mg/l, 4464 mg/l and 12840 mg/l respectively. Electrical conductivity (EC) was 42500 ?S/cm anions PO43- and Cl- were 17.1 mg/l and 13.8 mg/l respectively. Heavy metals were also analysed. Fe, Na, Zn, Cr, Pb and Ca were found 14.675 mg/l, 12006 mg/l, 1.5241 mg/l, 10.348 mg/l, 0.1818 mg/l and 0.4112 mg/l respectively. Biological treatment with aquatic plants, algae and their combination treatments were found to be effective for the reduction of some physiochemical parameters. Treatment conducted with Eichhornia crassipes was found most effective in reducing COD, EC, TDS and TSS. Mixed treatment resulted reduction of pH from 8.3 to 6.21. Both macrophytes and algae exhibited good heavy metal uptake tendency, but Eichhornia crassips was identified as most effective for the removal of heavy metals in the wastewater because of its extensive root system which provides to help the uptake of pollutants from the wastewater.

Stabiliser-free zinc oxide quantum dots have been utilised as a greener sensing platform for the quantification of arsenic at the parts-per-billion level. The method is free from common interference and applicable for real sample analysis.

Deafness prevention should focus mainly on chronic suppurative otitis media, otitis media with effusion, and impacted ear wax prevention, integrated within the primary healthcare system and addressing the equity issue.

Abstract:The objective of this study was to determine the efficacy of fine needle aspiration cytology in diagnosis and management of thyroid swelling. The study evaluated the predictive value of Pre operative fine needle aspiration cytology (FNAC) almost all of them presents with nodular thyroid swelling. Nodular goiter remains a problem of enormous magnitude all over the world, although exact data on incidence and prevalence are unavailable. In our country the national prevalence rate is 10-15%, which indicates, the whole country is endemic. The endemicity varies from one place to another. The highest prevalence rate in Bangladesh is in the district of Rangpur and Jamalpur, the range varies from 21-30%. Nodular thyroid disease is more prevalent than diffuse goitre. In a report from the thyroid clinic, BSMMU, Dhaka 32.67% of all thyroid patients had solitary nodules (Alauddin M, 2003).A solitary nodule has a higher risk of being malignant, than the multiple multinodular goitre (Hilal M, Al-Sayer et al., 1985).
