Abstract: In this investigation, an attempt was made to convert the organic fraction of municipal solid waste and the sludge from three different industries (Pulp and paper industry, Sugar industry and Dairy industry) into compost (value added fertilizer) using three different processes, i.e. Windrow composting, vermicomposting and a combination of windrow and vermicomposting (Twin Process) . For this purpose, a detailed analysis of treatments with different combinations and different ratios were done. In this study, a series of experimental studies were conducted with regard to bioconversion of organic fraction of municipal solid waste along with dairy waste water at different C/N ratios using combined composting and vermicomposting technology. The variation in physical and chemical parameters was monitored throughout the process. The results indicate that combined composting and vermicomposting of dairy waste water with municipal solid waste produces high quality compost.

Keywords: Vermicompost, Paper mill waste, Microbial consortia.
Abstract: The main objective of this study was to enrich the quality of vermicompost prepared from Paper Mill Waste (PMW) by adding a consortium of microbes. Paper mill waste comprising wood dust, fly ash and sludge from effluent treatment plant were blended with cowdung and vermicomposting done. To this mixture (Industrial Waste Vermi Compost, IWVC) a consortium of microorganisms were added in two stage, i.e. one during the precomposting stage of vermicomposting and other after precomposting for 30 days and vermicomposting for 60 days. The nutritional analysis of both the types of vermicompost were done. From the nutritional analysis, it was observed that the microbial consortia addition was effective after the vermicompost was ready and just before removing the earthworms. Comparison of this enriched compost was made with plain soil and garden waste vermicompost (GWVC) to study the growth of crops like ladies finger and brinjal. Addition after 90 days just before removing the earthworms from the compost proved more effective and the dose of vermicompost @ 2.0 tonnes per hectare gave maximum benefits. Trials were also done using different combinations of vermicompost on the growth of Gaillardia in pots. The addition of live formulates of biological organisms helped n mineralization of immobilized materials improving plant growth.

Abstract: Nano silica is the extremely fine silica that can be used as cement admixture in construction and civil engineering industries. Nano silica can be used to improve slurry impermeability and the mechanical properties of the hardened material. With the adoption of very fine silica particles in cement matrix, porosity and permeability were significantly declined to about 33.3 % and 99 % respectively and compressive strength grew. For conducting this experiment, blended cement has been used. The blended cement used here consists of ordinary Portland cement and flyash replaced to some percentages of cement. The percentage of replacement of fly ash replaced to some percentages of cement. The percentage of replacement of fly ash by cement is about 20 %, 40 %, 60 % and 80 % respectively. Fly ash is a fine, glass-like powdered substance obtained from gases created b y coal-fired electric power generation. Fly ash is an inexpensive substance which is used for replacing ordinary Portland cement in concrete, which thereby improves the segregation, strength and ease of pumping of the concrete. Fly ash is also used as a constituent in brick, block, paving, and the structural fills. Consisting mostly of silica, iron and alumina Fly ash is a pozzolana substance containing aluminous and siliceous material which for m cement in the presence of water. When it is mixed with lime and water they form a compound similar to Portland cement. The spherical structure of the particles reduces the internal friction thereby increasing the consistency and mobility of the concrete, allowing longer pumping distances. Increased workability means less amount of water is required, thus resulting in less segregation of the mixture. Even though fly ash is less dense than Portland cement, the produced concrete will be denser and results in smooth surface with sharper details. Class F of Fly ash, in which particles are covered in a kind of melted glass, greatly reduces the possibility of expansion due to sulfate attack, as may occur in fertilized soils or near coastal area. We have chosen Class F fly ash for replacing cement.

Abstract: Canopy variations of the trees lining the roads, at different parts of Mumbai city were observed and an attempt is made to relate the different canopy shapes with urban activity in the immediate vicinity. A tree survey was carried out along five classes of roads, Main Roads, Secondary Roads, Tertiary Roads, Western Express Highway and Eastern Express Highway in the city. The five most common trees encountered were peltrophorum pterocarpum (DC), Samanea saman (Jacq), Delonix regia (Hook), Thespesia populnea (L.), and Erythrna indica Lam. Canopy shapes of individual trees were recorded for comparison with a standard set. The canopy shapes showed variations within the species and in many instances deviated away from the normal canopy shape. More than 60 % of trees showed deviation from normal canopy shapes. Flattening of canopy in Samanea samann (Jacq), Peltophorum inerme (DC) and Erythrina indica Lam was very frequent. Order of sensitivities of the five species in terms of canopy shapes in the city, is Peltophorum pterocarpum (DC), Delonix regia (Hook), Erythrina indica Lam, Thespesia populnea (L), and Samanea saman (Jacq).

Abstract: The present study was undertaken to evaluate the feasibility of the biomass of Brevundimonas vesicularis to remove Zinc and Cadmium from their aqueous solutions and wastewater samples. The biomass of the bacterial species was first pretreated with 0.1 N NaOH solution and then interacted with solution of metal ions. Optimum conditions such as pH, biomass dose, contact time, initial metal ion concentration were determined experimentally. It was found that pH 6.0, biomass dose, 0.1 g in 100mL metal ion solution, contact time, 90 min and 100mg/L initial metal ion concentration were most suitable for removal of both the metal ions in single and in binary metal systems.The method d3eveloped for Biosorption of metals by the biomass of Brevundimonas vesicularis was applied for the removal of the metals from waste water samples. HNMR study showed that the metal ions interact with the biomass of the bacterial species through coordination.

Abstract: The present study aims in comparing the pollution limits followed in different countries and also studying the methods of treatment process and tannery waste water quality test followed by Common Effluent Treatment Plant at Ranipet, Tamil Nadu. The standards of Pollution limits for discharge of effluents into water bodies and sewers were compared between developing countries. It has been observed that India, Argentina, Sri Lanka, Bangladesh are lenient towards traditional small scale tanneries and no strict enforcement in maintaining quality standards in surface water is done as compared to South Africa. Tannery waste water quality test procedures followed in Common Effluent Treatment Plant (CETP) were studied and tests were conducted on samples collected in Palar River (Near Outfall) during the study period. It has been observed from the Effluent analysis results, that pH value and temperature of the samples are higher during summer season, since the dilutions of the samples are at low level, (i.e. River water not flowing) Suspended Solids, settleable solids, BOD, COD, Chromium content, sulphates, sulphides shows an increase in level of quantities during summer season. This increase in levels is due to dilution factor, which is less during summer season. (I.e. River water not flowing.)

Abstract: Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). In other words, water pollution can be defined as the contamination of water bodies, i.e. lakes, rivers, oceans etc. that occurs due to direct or indirect discharge of pollutants in to the water bodies. It has been suggested that it is the leading worldwide cause of deaths and diseases and that it accounts for the deaths and diseases and that it accounts for the deaths of more than 14, 000 people daily. Water is typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use, such as drinking water, and /or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. In this context for different samples designed as S1, S2, S3 and S4 were taken for chemical and bacteriological examination. The collection site of the four different samples were Barachhak village, Kalyanpur Housing, Ghagarburi Temple and Kalipahari Village. After chemical and bacteriological examination it was estimated that all the samples were contaminated and their parameters were higher than safe limit.

Abstract: When a RC moment-resisting frame is subjected to seismic load. The possible inelasticity is concentrated either in beams or in the beam-column joint regions. This is depends on not only the flexural capacity ratio of beams to column but also the details of both longitudinal and transverse reinforcement in the joints which affects significantly the shear strength and stiffness of the frame. Hence it is necessary to maintain the integrity of the beam column joints. Damage of the joints in the frame can result in instability of the structure and poor overall structural response. It has been shown that severe damage and collapse of many RC framed building in recent earthquakes are the results of poor reinforced details of beam-column joints. This paper presents the seismic performance of the reinforced concrete beam designed for seismic loads as per IS 1893-2002 with and without retrofitting of FRP and ductility recommendations are adopted as IS 13920-1993. Four specimens were cast with and without retrofitting and tested under cyclic loading, simulating earthquake actions. The beams are examined in terms of load carrying capacity, load deflection behavior, stiffness degradation factor, energy dissipation capacity, ductility factor and cracking characteristics. Based on the test results important conclusions are drawn and the advantages of retrofitting with FRP wrapped reinforced concrete beam have been established.

Abstract: Twenty three (23) isolates of Plant Growth Promoting Rhizobacteria (PGPR) from rhizospheric soils of Rajendranagar and Amravathi were isolated and identified based on their morphological, physiological and biochemical characteristics using standard methods. These test isolates were screened in vitro for PGPR properties like phosphate solubilization, siderophore, IAA, HCN productions, Antagonistic activity against Rhizoctonia solani, Sclerotium rolfsii and compatibility with commonly used pesticides molecules. The results revelaed that all the Rhizobium isolates showed nodulation on ground nut, black gram and soybean crops, 82.60 % of isolates phosphate solubilization, 91.3% for ammonia, 47.82 % for IAA, 70. 83 % for siderophores and 52.17 % for HCN productions. Out of 23 Rhizobium isolates 4 isolates ABuR2, ABpR2, ARpR1 and AmaR showed inhibition potential against both Rhizoctonia solani was Sclerotium rolfsii to a lesser extent based on per cent inhibition and vice versa. Hence it can be inferred that the Rhizobium isolates CRuR1, CRuR2, SBpR, SRuR2 and SRpR could be considered for their biocontrol activity. Among the pesticides tested Tebuconazole (fungicide), Thiacloprid (insecticide) and Pretilachlor (herbicide) were found to inhibit Rhizobium at recommended /half recommended dosage. However other fungicides, insecticides and herbicides were compatible with all the isolates tested. Out of the 23 isolates tested for their compatibility with the four each of the fungicides, insecticides, herbicides and based on their PGPR attributes and antagonistic activity, the isolate of Rhizobium isolate ARpR1 showed potential as PGPR.

They were screened in vitro for PGPR properties like phosphate solubilization, siderophore, IAA, HCN productions, Antagonistic activity against Rhizoctonia solani, Sclerotium rolfsii and compatibility with commonly used pesticide molecules. The results revealed that 50 % of the Bacillus isolates showed positive results for phosphate solubilization, 100 % for ammonia, 91.6% for IAA, 70.83 % for siderophores and 58.33 % isolates showed for HCN productions. Out of 24 Bacillus isolates 4 isolates CRuB2, SBpB2, ABuB1 and ARpB2 showed inhibition potential against both Rhizoctonia solani was showed by CRuB2, SBpB2, AbuB1 and ARpB2 showed inhibition potential against both Rhizoctonia solani and Sclerotium rolfsii. The maximum percent inhibition against Rhizoctonia solani was also inhibitory to sclerotium rolfsii to a lesser extent based on percent inhibition and vice versa. Hence it can be inferred that the Bacillus isolates CRuB1, CRpB2, SBuB1, SBpB1, SruB1, SRuB2, ARuB2 and ARpB1 could be considered for their bio control activity. Among the pesticides tested Azoxystrobin (fungicide), Flubendiamide (insecticide) and Propaquizafop (herbicide) were found to inhibit Bacillus at recommended /half recommended dosage. However other fungicide, insecticides and herbicides were compatible with all the isolates tested. Out of the 24 isolates tested for their compatibility with the four each of the fungicides, insecticides, herbicides and based on their PGPR attributes and antagonistic activity, the isolate of Bacillus isolate SBpB2 showed potential as PGPR.

Abstract: There is cooperative sugar mill and distillery commissioned four decades ago, at Aska, in the vicinity of a college. The industry uses raw sugarcane and is generating huge quantity of effluents which is main polluting source to land surface water. Agro-industrial waste or any cellulose based industries unutilized organic matter and cause environmental problems like dispersing foul odour, occupying vast areas, ground and surface water pollution etc. Effluent originating from sugar industry is a rich source of organic matter and nutrients like nitrogen, phosphorus, potassium, calcium, magnesium, bicarbonate and sulphur. In addition, it contain sufficient amount of micronutrients. Basing on above view, a study was conducted to known the quality of effluent generated from sugar industry and influence of its different dilution on Brinjal plant. Brinjal plant (Solanum melongena L) is an important vegetable of the people, which contains important alkaloids, minerals, vitamins and other nutrients. A pot culture experiment was conducted in botanical garden of Aska Science College campus to study the influence of different dilution of effluent on the growth and biochemical parameters of the Brinjal plant. The results showed that, the vegetative growth viz. shoot length, root length, shoot weight and root weight of plants were highest in 20 mL/kg of soil treatment. The similar trends of results were also noticed in chlorophyll, carbohydrate and protein contents of 30 days old brinjal plant. The pot experimental studies suggest the possibility to using judicious application of crude effluent will improve crop productivity and alleviate environmental pollution problems. Awareness should be created among the farmers to economise crude sugar industry effluent through dilution in proportionate manner and improve the crop system.
