Abstract: Sugarcane hot water balance shows that the water content of sigarcane itself is more than sufficient for internal processing. Surplus internal water is available for external use. By recycling, reuse and good house keeping, external consumption can be minimized. The polluted water is treated by anaerobic digestion activated sludge process- pressure filtration and activated carbon. The treated water is recycled to reservoir to utilize for factory cleaning, washing, cooling water make-up, volony, gardening and irrigation. Alternatively, wastewater is made zero through bio-composting.

Keywords: Bird species richness Habitat structure Habitat simplification Harena forest Tree cutting
Abstract: Human simplification of habitat in the Harenna forest mainly happens by permanently removing woody vegetation. We evaluated the impact of such simplification of habitat on bird species richness. Birds were counted using the point count method at points that were laid out along transect lines, and their presence/ absence,species richness was worked out. By establishing 50m by 50m quadrates at bird counting stations, we counted the number of basal remnants of cut trees and we measured vegetation structure variables such as % grass, % other herbs, % shrubs, % bush and % canopy (tree cover). Tree bush and shrub covers did have significant positive correlation with bird species richness. As the magnitude of tree cutting increased species richness of birds declined significantly. Similarly with bird species richness, structural variables such as tree, bush and shrub covers did have significant negative correlation with the tree cutting variable. Due to this, we carried out Principal Component Analysis and the first component that was influenced mainly by tree cover and tree cutting variables significantly explained 84.7% of the variation in bird species richness is a stepwise multiple regression analysis. Bush and shrub cover did also have significant positive contribution in explaining bird species richness is noteworthy. Results showed habitat simplification through tree cutting has significant negative impact on bird species richness.

Keywords: Fly ash HVFA concrete Plasticizer Structural properties Pozzaolanic reaction
Abstract: A large number of structural properties of plan concrete are improved with addition of admixtures to concrete. It is well known that the addition of fly ash to plain concrete improves workability, strength, durability, less permeable and more stable. In concentional concrete the flexural strength reaches a maximum value between 14 and 28 days. In high volume fly ash (HVFA) concrete the strength keeps on increasing with age because of pozzolanic reaction of fly ash and strengthening of the interfacial bond between cement paste and aggregate. The use of fly ash as a partial replacement for Portland cement will usually reduce water demand and bleeding of HVFA concrete ranges from negligible to very low. Only few reserch works have been carried out earlier on flexural study on R C conventional beams without fly ash. Therefore in this investigation an attempt has been made to study any likely improvement on the effect of fly ash on the properties of HVFA concrete in R C beam elements with confinement of stirrups in compression zone. It has suggested that the effective use of fly ash minimizes the disposal of fly ash, which also solves an environmental problem. This HVFA concrete is easy to pump, consolidate and finish the surface, free from cracks, reduces carbondioxide emissions, superior environmental friendliness, reduction in stone mining since it consumes less volume of Portland cement. The methodology adopted above improves ductility and improves the rotation capacity of the joints of framed structure, thus, improving the ultimate load carrying capacity. An attempt is also made to compare the load versus deflection of the HVFA concrete beams with conventional RCC beams and evaluated the perfomances of the proposed method of confinement. The results indicated that the confinement in the form of stirrups improves the ultimate strength and ductile behaviour of the concrete (IS 3812-1981). An attempt has been made in the present paper to highlight the utilization of fly ash in construction.

Keywords: Natural resources Arpa river basin Chhattisgarh state
Abstract: Chhattisgarh State is mostly dominated by tribal and backward people. The state has rich endowment of natural resources in terms of minerals, forests and water bodies. The state has a forest cover of around 44%, which represents diverse tropical flora and fauna. Mahnadi,Shivnath, Son, Arpa, Kharoun, Hasdeo and Indrawati are the rivers. The main forest types that are classified on the basis of species composition include Sal forest, being the dominant species distributed throughout western and eastern Belghana. However, the teak forest are found throughout the Khondri range while the mixed forests are distributed in the southern Belghana where the species of bamboo, sal, muhua, bija, sissso etc, are prominent. The third important resource in aforementioned region is soil and the geology of watershed that determines the infiltration of water, percolation of water, and controls the runoff and soil erosion of the area. The most eidely distributed soil types of the area are loamy sand, loam, clay. The black cotton soil and lateritic or red soil are widely dominating in parts of study area. It was inferred from the study that Apra river basin is very rich in natural resources, which need systematic management without overexploiting them so that socioeconomic standards of this tribal area can be uplifted in a productive manned.

Abstract: Arsenic is a common menace in the state of West Bengal particularly in the district of 24-Parganas (North) and (South). The major source of arsenic in nature. Soil samples collected from one such particular location Baduria were tested for the presence of arsenic (As), and on an average the As content of the soil was 2.18mg/kg. Different bacteria were isolated by serial dilution and were also tested for As tolerance. On the basis of their tolerance, three organisms (viz. C-7,A-2,A-1) have shown remarkable percentahe uptake of As 43%,22.17% and 14% respectively, which was highest for C-7 strain.Azithromycin and Streptomycin were found to be more effective to control C-7 with an inhibition zone of 4.5 cm, but for A-2 and A-1 it wasAzithromycin with inhibition zone of 3.8cm and 3.5cm respectively. These organisms were characterized and identified by 16S rDNA technique, BLAST results and the cluster analysis by NTSYSpc ver. 2.02e program, and found to be Bacillus sp.strain CCBAU 51490(C-7) (GenBank Accession NumberEF377314.1), Bacillus suntills sub sp. subtills strain DSM 10(GenBank Accession Number NR_027552.1) (A-2) and Pseudomonas otidis strain MCC 10330 (GenBank Accession Number NR_043289.1) (A-1). They can be used in the tratment of As contaminated sludge generated industrially from As treatment plant. This can give a new insight in microbial arsenic trapping with minimum toxic implications in the nature.

Keywords: Loess slope Runoff energy Runoff power Shear stress Soil erosion
Abstract: In this reaserch, soil erosion and sediment yield were calculated by runoff shear stress, runoff energy consumption and runoff power theory. Results indicated that a linear relationship existed between the average runoff shear stress and sediment yield. Soil erodibility in the experiment was 178.5g/(Pa-min), and the critical shear stress value was 0.54 Pa. Results from energy consumption implied that there was also a linear relationship between sediment transportation and energy consumption of runoff unit width: Dr=14.61 (^-E-0.37), which indicated that the soil erodibility was 14.61g/J, with a critical energy consumption of 0.37J/(min-cm). Results from runoff power theory showed that sediment transportation increased with increase in runoff power, and the simple linear relationship was also regressed: Y=8942.2x, Generally, these three theories each showed ertain advantages in describing the soil erosion processes on the slope, among which the results from energy consumption theory were simpler, more accurate, and proved more convenient in describing soil erosion on the slope.

Abstract: This study described the removal of Ag(I) from wastewater using macrofungus Pleurotus platyus in a packed bed column. The effect of opreating parameters such as bed hight, flow rate initial metal concentration were investigated on removal of Ag(I) under optimized conditio. The breajthrough curve profile signifled that the breakthrough time and exhaustion time increased with an increase in bed height and a decrease in flow rate and initial metal concentration. The data were supported by 3D mesh diagrams and perturbation plots obtained from 2D factorial design. The column data were analysed using four models viz., BDST model, Empercal model, Thomas model and Yan model. The BDST model was found to be the best to fit the breakthrough curves at experimental conditions. The column was regenerated using 0.01 M HCI solution and sorption-desorption studies were out for three cycles. The obtained results implied that P. platypus may serve as suitable adsorbent material for the removal of Ag(I) from wastewater.
