Subject: A mathematicl study on anaerobic digestion process treating vegetable waste or energy recovery
Keywords: Time-lag model, biodegradability, anaerobic digestion (AD), biogas production
Abstract: This work primarily deals with a simple time-lag model for biogas production from anerobic digestion (AD) of vegetable wastes in a batch digester. The model is capable of predicting the S-shaped nature of the cumulative biogas yield as a function of retention time observed experimentally. The model is calibrated against biogas production results obtained from anaerobic digestion of vegetable wastes by variation of process parameters, like total solids, particle size and operating temperature, respectively. For these studies, the fit of the model to the experimental data has an average root-mean square 9RMS) deviation of19%. The model also led to the formulation of two measures/indexes of biodegradability of vegetable wastes. These measures are proportional to the biogas potential of vegetable waste showing susceptibility towards anaerobic digestion.

Subject: Plant growth promoting effects of multi-trait Rhizobacteria on Vigna radiata
Keywords: Phosphate solubilizer, Azotobacter, Azospirilium,green gram, seed inoculation
Abstract: Microbial inoculants play a significant role in regulating the dynamics of organic matter decomposition and availability of plant nutrients, such as nitrogen, phosphorus, potassium. Biofertilizer is eco-friendly and possess no pollution threat to our environment, unlike chemical fertilizer which causes environmental hazards, such as water pollution, soil humus reduction, increased susceptibility to pests and disease. The microorganisms in biofertilizer restore the soils natural nutrients cycle and build soil organic matter. In the present study phosphate solubilizing bacteria and free-living nitrogen fixing bacteria were isolated from the rhizosphere. The ability of the organisms to produce enzymes was studied. The plant growth promoting studies were carried out on green grams. The seeds were inoculated with different combinations of organisms and their growth characteristics were studied after 45 days. The shoot length, root length, leaf chlorophyll content., the diameter of the stem and the size of the leaf were determined. The seeds inoculated with the combination of three organisms (Phosphate solubilizer, azotobacter and azospirillum) showed the highest plant growth characteristics than the other groups. The presence of these organisms made nitrogen and phosphorus available for the plants to grow.

Subject: Lead bioremediation using spinach (Spinacia oleracea L)
Keywords: Lead, Bioremediation, Spinach, Toxicity
Abstract: The increase in the human activities has led to the increase in the addition of heavy metals in the earth ecosystem affecting both the flora and fauna. Lead toxicity is a major concern with respect to the health issues associated with lead. Bioremediation of lead using green plant could be an effective as well as environment-friendly technique for easy removal of lead from contaminated soil. The current study demonstrates the use of spinach (Spinacia oleraceae L) for the bioremediation of lead from the soil. Spinach was grown in pots containing different lead concentration and the lead uptake was measured in different parts of the plant. The study concludes that spinach was found to be an effective plant for the uptake of lead from the contaminated soil.

Subject: Some studies on occupational hazards and safety in construction industry
Keywords: Occupation, hazard, safety
Abstract: Construction is the second largest economic activity in India. It is a labour intensive technology through mechanization occurs in the present scenario. Construction offers employment opportunities to all categories of people, skilled and unskilled labour. The workers at construction site are involved in works, such as working with mortar, cement, crushing stones, loading/unloading of materials, cutting, grinding, welding, lifting, shuttering, scaffolding, reinforcement steel works, sawing, etc. Health hazards in the construction industry cane be grouped under physical hazards (like fungi, insect bites), ergonomic hazards (like repetitive works, awkward postures, loads lifting) and mechanical hazards (like protruding parts, sharp objects).Accidents are the end products of unsafe acts and unsafe conditions of work. However, the accidents are preventable-they do not just happen. In the present work, four construction sites have been chosen to study the occupational hazards and safety issues at the construction sites. Under physical hazards, noise pollution monitoring has been done during concrete mixing for roof slab. Under chemical hazards, bio-monitoring of dust pollution has been carried out at the construction site. Under ergonomic hazards, repetitive work, loads lifting, improper posture, have been identified. Safety aspects regarding safety rules, sign boards, use of safety equipment have been studied.

Subject: Comparative analysis of performance and emission characterisitics of thermal barrier coated diesel engine using biodiesel fueled with diesel fuel
Keywords: Thermal coating, engine emission, diesel engine performance, injection pressure
Abstract: Nowadays in the area of internal combustion engines, improved engine performance, lowered specific fuel consumption and controlled emission levels are the three major challenges. Different methodologies are being implemented to increase the combustion temperatures and reduction of emissions. The thermal barrier coating is one of the possible solutions to solve such a problem. The various types of nano coating ae being used in the engine components to increase the temperatures and reduce the emissions. In this experimental study, nano mateirals, such a zirconium oxides and yttrium are coated over the piston head. The zirconium oxide stabilized with the yttrium was coated at the top of the piston and NiCral as a bond coating was applied over the piston head for a thickness of 500 µm. The injection pressure has been altered from its standard level and maintained at 200 bar. Then the ceramically coated diesel engine made to run with the jatropha oil and rubber seed oil are equally mixed and blended with the pure diesel fuel before supplied into the engine cylinder. The engine performance parameters, such as brake thermal efficiency and specific fuel consumption were obtained. Emission characteristics, such as carbon monoxide, unburned hydrocarbons, nitric oxide and carbon dioxide were measured by using an exhaust gas analyzer. From the test result of the engine with thermal barrier nano coating, it was observed that the brake thermal efficiency 9BTE) and oxides of nitrogen (Nox) were increased and brake specific fuel consumption (BSFC), carbon monoxide 9CO) and unburned hydrocarbon (UHC) were reduced from 15 to 20 % .The tests were carried out for a 20 % of biodiesel blend with the pure diesel fuel at room temperature and provided better specific fuel consumption and also a considerable reduction in the exhaust emission.

Abstract: Investigations were carried out to observe the adsorption of Rose Bengal dye over activated carbon prepared from Prosopis juliflora. Evaluation of the suitability of the adsorbent was performed using scanning electron microscope (SEM) and fourier transform infrared spectroscopy (FTIR) characterization. After the amalgamation of the activated carbon into a polymeric bead, chitosan was coated on the bead as a means of increasing the removal efficiency. At optimized equilibrium conditions, adsorption experiments were carried out and the removal percentage was calculated by checking the absorbance at 547nm.The removal efficiency of the dye was illustrated using the adsorption dynamics and isotherm kinetics. The Ho's pseudo-second order model was used to ascertain the rate kinetics as the model suited the present adsorption studies perfectly.

Keywords: Scenedesmus dimorphus, Photo-bioreactor, lipid, nitrogen, algae, nutrient stress
Abstract: The lipid accumulating potential of Scendesmus dimorphus was investigated using modified Bold's basal medium (BBM) with NaNO3 serving as nitrogen source. The alga species Scenedesmus dimorphus showed a lipid content of 21.4% when grown under normal growth condition in continuous mode. The average lipid productivity during the log phase of cultivation was 0.0107 g/Ld. The photo-bioreactor was illuminated at a light intensity of 110 ±5 µmol/m2s with a light/dark cycle of 12:12 hr, respectively. The reactor temperature was maintained at 26± 1°C, while the pH ranged between 7.8 ±0.2 during the investigation. Scenedesmus dimorphus when stressed exhibited its ability to undergo tactical changes in photosynthetic carbon partitioning and thus altering its cellular composition leading to lipid accumulation. The effect of nitrogen limitation on Scenedesmus dimorphus was investigated in batch process. The optimum nitrogen dosage was found to be 3.53 mM/L as NaNO3-. Thus, a compromise has to be reached in obtaining between the algal lipid content and its growth pattern, in order to achieve a high lipid accumulation. With the manipulation of nitrogen availability, we demonstrated that highest yields of lipid 0.0325 g/Ld, is achievable in nitrogen limiting condition at 3.53 mM/L with a lipid content of 36%.

Abstract: The entire North Bengal is famous for the 3t's-Tea, tourism and timber contributing extensively towards the socio-economic development of the region. Tea in this area is famous worldwide for its affluent essence, colour and taste. Here tea industry is the major one yielding high profit. Tea workers are directed to use chemical fertilizers and pesticides for the better profit in the tea gardens of this region which ultimately affects the soil, surrounding water, human health as well as whole environment. The local environment is gradually deteriorating continuously due to frequent use of chemical materials as pesticides are used for the high yield and pest control. The most popular chemical pesticides used are ethion, quinalphos, sulphur, fenazaquin,bifenthrin,propargite, fenvaerate, etc. Besides these simazine, paraquat, oxyfluorfen, emamectin benzoate, etc., are also sed by all the tea cultivators in different ratios. Most of the chemical pesticides are not easily degraded and remain in the soil for a long period causing soil pollution as well as the environment. Surrounding water was also found to be degraded to some extent due to frequent use of pesticides in the studied area. The present study also shows serious impact of chemical pesticides upon the health of tea workers.

Abstract: Prosopis juliflora bark activated carbon-cobalt ferrite magnetic composite (PJBAC-CFC) was synthesised by the auto-combustion method and employed for the removal of direct brown2 (DB2) from aqueous solutions. Th prepared composite was characterized by powder XRD, SEM, EDAX, AFM, N2 adsorption-desorption isotherm and magnetization measurement. Operating factors influencing the rate adsorption, namely initial dye concentrations, doses of sorbent materials, present time intervals, variable pH and temperature environments are substantiated by batch equilibration method. Adsorption is observed to be more pronounced at pH 2. The magnetized composite material exhibited enhanced sorption characteristics. The isothermal adsorption data fit well with Freundlich isotherms. Kinetic studies favour the system to follow the second order. The outcome of the present work indicates that Prosopis juliflora bark activated carbon-cobalt ferrite magnetic composite can be effectively used as cost-effective potential adsorbent for trapping the dye molecules.

Abstract: Soil stabilization improves the physical properties, like shear strength, bearing capacity and stability of soil. This can be done by the use of waste material so that the waste material can be utilized in a good way with the use of some new techniques compaction and addition of suitable admixture, etc). This technique can be effectively used to meet certain challenges. In hilly regions, it is very important to stabilize the soil to reduce the chances of natural causes, like land sliding, soil erosion. Plastic is one of the waste materials which are non-biodegradable so that it can be used to stabilize the soil. It is helpful in both ways-To reduce pollution and to stabilize the soil. Plastic bag strips can be used to reinforce the soil by mixing it with the soil and compact it with a mechanical technique which increases the CBR value of the soil. The result of the CBR test shows that the use of plastic strips increases the strength of the soil effectively.

Subject: Torism influx apotential noise pollution threat: A case study of Udaipur
Keywords: Environmntal problems, Tourism, Noise pollution, equivalent noise level
Abstract: The rapid development in the tourism industry is directly or indirectly increasing environmental problems of increasing noise level. Noise is an important pollutant of Environemtal causing various health hazards. The paper discusses the noise pollution status of an important aesthetic, recreational and commercial tourist destination-Fateh Sagar Lake and Pichola Lake, in the district Udaipur of Rajasthan, in peak tourist season compared with lean tourist season in the year. It examines the noise levels caused due to various sources at the site and evaluates the conclusions drawn. The results of noise level monitoring revealed the fact that due to a higher amount of tourist in peak tourist season noise level monitoring revealed the fact that due to a higher amount of tourist in peak tourist season noise level was enhanced. The average equivalent noise level was increased from 65.2 dB to 79.7 dB (a) and 64.82 dB to 77.28 dB 9A) from lean to peak tourist season, at Fateh Sagar Lake and Pichola Lake, respectively. The highest equivalent noise levels during peak days at Fateh Sagar is79.7 dB at 20:00 hour which was 22.23 % higher in comparison with lan days and 44.90% higher than the standard of Central pollution Control Board (CPCB).Similarly, the highest equivalent noise levels in Pichola during peak days was 77.28 dB (A) at 20:00 hour which was 19% higher in comparison with lean days and 40% higher than the standard o Central Pollution Control Board (New Delhi) on comparing the noise levels of lean and peak seasons. The p value (2 tailed) is equivalent to 0.0007, through standard criteria, this variation is situated to be exceptionally statistically significant. This scientific pursuit clearly indicates that the noise pollution is directly proportional to the tourist influx at the two tourist destinations in Udaipur city.
