Morphology of esophagus of Black Bengal Goat

The morphology of esophagus of Black Bengal goat was studied 6 Black Bengal goats of over six months of age of both sex in the Department of Anatomy and Histology, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh using. The topography, shape, size, esophageal length including cervical and thoracic parts were measured. The esophagus was sampled at six sites - cranial cervical, middle cervical, caudal cervical, at the level of thoracic inlet, at the middle mediastinum and at the level of cardia. The esophagus was 45-50 cm long. The cervical part of esophagus was 13-15 cm long and the thoracic part was 32-30 cm long. The highest and lowest diameter was found 5.1 cm and 3.2 cm at the cardia and at the cranial cervical part of the esophagus respectively.

Effects Of Textile Industrial Waste Water And Uptake Of Nutrients On The Yield Of Rice

An experiment was conducted at Mouchack textile industrial area of Gazipur for two consecutive years (1999-2000) to study the effects of use of industrial waste water on the yield, nutrient content, and uptake of Boro rice. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The six treatments in this study were: T1: uncontaminated field + fresh water, T2: uncontaminated field + mixed water, T3: uncontaminated field + contaminated water for non-contaminated field, and T4: effluent contaminated field + fresh water, T5: effluent contaminated field + mixed water, T6: effluent contaminated field + contaminated water for contaminated field. Among the six treatments, uncontaminated field + fresh water (T1) showed the best positive effect on rice. The N, P. K, and S contents and uptake were higher in T1, but Zn, Mn, Fe, Cu, and Pb were higher in T6 treatment. The treatment T1, gave the highest grain yield (5.23 t/ha in 1999 and 5.40 t/ha in 2000), followed by mixed water (4.19 t/ha in 1999 and 4.24 t/ha in 2000) in both the growing seasons.

Assessment of irrigation water quality of Bogra District in Bangladesh

Some important physio-chemical parameters of surface and groundwater of Bogra District were evaluated for the criteria of irrigation water quality. Forty four water samples were collected in the peak dry season (December-April) from different areas of Bogra District. The study revealed that temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), sodium adsorption ratio (SAR), soluble sodium percentage (SSP), residual sodium carbonate (RSC), total hardness (Ht) and Kelly’s ratio of waters were found within the permissible limits for irrigation purposes. Any initiative for surface and groundwater development for planned irrigation practices is highly encouraged. Key Words: Irrigation water (surface and groundwater); quality; Bogra District.

Study on Rehydration Characteristics of Dried Lablab Bean (Lablab purpureus) Seeds

The present study was carried out to evaluate the rehydration characteristics of solar and mechanically dried lablab bean (Lablab purpureus (L.) sweet; hitherto Dolichos lablab) seeds. Bean seeds with and without coat were used to study the rehydration properties. The rehydration ratios were higher for both mechanically and solar dried bean seeds without seed coat than those with coat. Mechanically dried without coat bean seeds had rehydration ratio of 2.34 while with coat was 2.06. For mechanically dried samples, the co-efficient of reconstitution were 0.58 and 0.56 for bean seeds without and with coat, respectively, and were higher than those of solar dried samples having co-efficient of reconstitution of 0.54 and 0.52 for bean seeds without and with coat, respectively. For both mechanical and solar drying the rehydration rate constant was higher for bean seeds without coat than those with coat. Both rehydration ratio and rehydration rate indicated that mechanically and solar dried bean seeds samples without coat showed better reconstitution properties than those with coat. Both fresh and dried bean seeds without seed coat gave higher nutrient content than their counterpart with coat. Solar and mechanical dried seeds were good source of nutrients.

Reduction of COD and pH of Textile Industrial Effluents by Aquatic Macrophytes and Algae

Effluents samples collected from post discharge of equalization tanks of local compositetextile mills of Saver were treated with aquatic macrophytes, algae and their combination. Theywere found to be effective for the reduction of chemical oxygen demand (COD) and pH. Sixty nineper cent of COD was reduced with the combination treatment of Nostoc, Eichhornia crassipes andPistia stratiotes. With the combination treatment of Nostoc and E. crassipes reduced 65 per centCOD in glass containers. pH was reduced from 11.2 to 8.6. Between earthen and glass containers,glass container was found to be more effective.Key words: Industrial effluents; COD; pH; Aquatic macrophytes; AlgaeDOI: 10.3329/jbas.v34i1.5487Journal of Bangladesh Academy of Sciences, Vol.34, No.1, 9-14, 2010
