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.)

Keywords: Water pollution, Pollutants, Anthropogenic contaminants, Biotic communities.
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.

Abstract: Twenty four (24) isolates of plant growth promoting rhizobacteria from rhizospheric soils of Rajendranagar were isolated and identified. 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.

Abstract: E-waste has become an immediate and long term concern as its unregulated accumulation and recycling can lead to major environmental problems endangering human health. Reusing and recycling are the effective ways of dealing with E-wastes. While recycling appears to be safe method to utilize or dispose E-wastes, it can be a misleading characterization of disparate practices including dismantling, shredding, burning, exporting, etc. which are mostly unregulated and often create additional hazards itself. Polycarbonate in landfills is definitely an environmental nightmare. These wastes can be reduced by properly recycling and converting them into some useful products. This work deals with the proper reuse of compact disc waste polycarbonate. The fabrication of polymer composite exhaust fan blade made up of E-glass fiber reinforced with recycled polycarbonate and epoxy by hand lay-up method to be carried out. The benefits of changing to the new blade material particularly include better quality, greater resistance to corrosion, weight reduction and cost. The mechanical properties to be characterized by tensile strength, flexural strength, impact strength, wear rate tests and surface properties by Scanning Electron microscope analysis.

Abstract: In the present study, physico-chemical and microbiological characteristics of the drinking water, and bore well water were studied from Bapuji nagar (Solapur, Maharashtra) in 2013. Total 8 water samples were collected from different locations in and around study region. The physicochemical parameter like, pH, dissolved oxygen (DO), Biochemical Oxygen demand (BOD), Chemical Oxygen demand (COD), total hardness (TH), Alkalinity, chlorides, CO2 and microbial parameter like MPN, bacterial and fungal colonies were determined. Electrical conductivity, total dissolved solids, total aerobic microbial count and most probable number were maximum in S-3 sample. pH, hardness and DO were observed higher in B-6, S-8, S-10, S-12-13 respectively. No coliforms were observed in samples S-6-9 and S-14-16. The results suggested that the bore well water samples collected from in and around study region was above the limit of WHO standards as compared to tap water. Pre treatment of these waters for drinking purpose is required as well as attention of Solapur Corporation is very important.

The adsorbent reinforced with polyaniline has good adsorption characteristics with a surface area of 1028 m2/ g. Column mode adsorption study was carried out by using PPAC as an adsorbent packed in a column for the removal of a reactive dye (Reactive Blue 19) from aqueous solution. The effect of operating parameters such as flow rate, bed height and inlet dye concentration on the sorption characteristics of RB 19 was investigated at room temperature (30?C) and the natural pH of dye solution. The kinetic models suggested by Thomas, Yoon-Nelson and Bohart-Adam were employed to study this adsorption system. Out of the three models tested for the adsorption of RB 19 onto PPAC column, the YN model provides excellent fit with very high r2 (0.9783 to 0.9955) and low Sd (0.10 to 0.65).

Abstract: Daha river, a threatened seasonal river of eutrophicated nature in the Gopalganj district of Bihar was studied for its degradation and possible restoration practices. The study revealed high rate of sedimentation and agricultural activities, changes in water quality and biotic community were observed. The agricultural activities have led to high input of N and P fertilizers along with pesticides being used by the farmers. The positives response of restoration practices was observed with partial improvement in fish-productivity due to hindrance factors acting upon severe fish species.
