2. SOLID WASTE MANAGEMENT/SOIL STABILIZATION. SOME STUDIES ON GEOTECHNICAL CHARACTERIZATION OF DREDGED SOIL FOR SUSTAINABLE DEVELOPMENT OF DAL LAKE AND ENVIRONMENTAL RESTORATION
Dredged soil is a solid waste generated due to dredging of Dal Lake. The Dal Lake has been the centre of Kashmir civilization and is among the most beautiful National heritages. This lake with its multi faceted eco system and grandeur has been inviting the attention of national and international tourists. The urban lake, which is the second largest in the state, is integral to tourism and recreation in Kashmir. But during the past few years grave concern is being voiced by people from different walks of life over the deteriorating conditions of Dal Lake. It has been estimated that on an average 90,000 tons of silt flows annually into the lake resulting in large quantities of silt deposits in the lake. The problems of Lake have been well recognized and efforts are on to save it. The scheme for shoreline dredging of Dal Lake has been formulated with the primary objective to help in Eco regeneration and sustainable development of the lake. Dredging of the Dal Lake generated the dredged soil in large quantity posing serious disposal and environmental problems all around the Dal Lake. Concern over environmental effects of dredging, disposal of dredged soil, and the increasing unavailability of suitable disposal sites, has put pressure for characterization of this soil as a resource for various beneficial uses/engineering applications. For all above applications, a brief study about some physical and mechanical properties of dredged soil forms an important consideration, which will help in proper use of this unwanted soil as well as sustainable development of the Dal Lake. Hence, using dredged soil has a two fold advantage. First, to avoid the tremendous environmental problems caused by large scale dumping of dredged soil and second, to help in sustainable development of the world famous lake in the capital City Srinagar.
3. DESIGNING AN ENERGY STORAGE SYSTEM FUZZY PI CONTROLLER IN MICROGRID FOR ISLANDED OPERATION
The microgrid is operated in the grid connected mode and the islanded mode according to the upstream grid. Commonly, microgrid operates the grid connected mode. But, when a fault occurs in the upstream grid, it should disconnect and shift into islanded operation mode. It is important to maintain the voltage and frequency constant values in islanded mode. To achieve these management goals appropriately, In this paper, the coordinated control strategy between Diesel generator and BESS(Battery Energy Storage System) is needed. And a fuzzy PI controller is proposed to improve the frequency and voltage control performance of the BESS. The performance of suggested Fuzzy PI Controller and coordinated control were simulated by PSCAD EMTDC.

5. THE PERFORMANCE EVALUATION OF A DISPLACEMENT SURFACTANT USED IN EXTRA LOW PERMEABILITY RESERVOIR
According to the characteristics of the extra low permeability reservoir in Changqing Jingan oilfield, surfactant flooding experiments were conducted in physical models by considering the interfacial tension between crude oil and surfactant solution, the emulsifying ability of surfactant as the main index. The results show that surfactant TS can enhance the imbibition displacement ability of the injected water the oil displacement efficiency would increase 5% based on water flooding by injecting 0.2% of surfactant solution into this extra low permeability reservoir, which is significantly higher than that in high permeability and low permeability.
6. STUDY ON THE CHARACTERIZATION OF GAS CHANNELING IN HOMOGENOUS RESERVOIR
Aiming at the limitations of the characterization of gas channeling strength at present, the gas channeling coefficient is defined by analyzing the dynamic gas ratio curves of CO2 flooding in tubes. Natural gas flooding experiments are conducted to verify the precision of the defined coefficient, and the results show that the precision could be as high as 0.03, the defined coefficient could be used to preliminarily evaluate gas channeling during gas flooding. The results also show that the defined coefficient is highly sensitive to displacement efficiency, approximately 0.015 change would be induced by per unit change in displacement efficiency.
7. STRESS SENSITIVITY OF HEAVY OIL RESERVOIR AND ITS INFLUENCE ON WELL PRODUCTIVITY
To investigate the characteristics of stress sensitivity of heavy oil reservoir and heavy oil, experimental study were carried out using core flooding system and on line high pressure caplastometer respectively. Results of experiments show that the core permeability of heavy oil reservoir show exponential decay along with the decrease of fluid pressure, while the viscosity of heavy oil show linear decrease. Based on the experiments, a new productivity equation of heavy oil reservoir with both permeability and viscosity sensitivity being taken into account was developed and field applied. The results reveal that well productivity with the consideration of permeability sensitivity is lower than that without the consideration of it and well productivity with the consideration of viscosity sensitivity is higher than that without the consideration of it. In the case of both permeability and viscosity sensitivity being taken into account, the viscosity sensitivity can to some extent weaken the influences of permeability sensitivity on well productivity. Moreover, well productivity of heavy oil reservoir increases with the increment of viscosity sensibility coefficient. The newly developed productivity equation can simulate the development characteristic of heavy oil reservoir more accurately and has certain advantages over the existing productivity equations.
8. DEVELOPING A GEOSPATIAL BASED APPROACH TO LOCATE WIND FARMS IN POLLACHI TALUK, TAMIL NADU, INDIA
Selecting the location for wind farm is a complex process involving not only technical feasibility, but also physical, economic, and environmental requirements that may result in conflicting objectives. Such complexities necessitate the simultaneous use of Geographical Information System (GIS), Boolean Logic and Fuzzy logic. GIS was applied based on a set of criteria derived from the spatial aspects, physical, environment and economical. Multi criteria evaluation (MCE) is perhaps the most fundamental of decision support operations in geospatial technology. This paper reviews two main MCE approaches employed in GIS, namely Boolean and Fuzzy logic. Aintegrated model was developed to evaluate the potential locations of wind in Pollachi Taluk, Tamil Nadu. This integration could benefit investors and decision makers. The key idea of this paper is to explicate the procedure of getting a prototype GIS application to offer a scheme for supporting location decisions with regard to the carrying out of wind energy developers.

R. Lokesh, V.S. Senthil Kumar, C. Rathinasuriyan, R. Sankar
In this paper, AA 6063 alloy was friction stir welded under the submerged condition to obtain the optimum welding condition for maximum hardness. Rotational speed, welding speed and tool pin profiles (cylindrical, threaded and tapered) were taken as process parameters. An L9 orthogonal array with three levels and three factors was designed and executed for conducting trials. The analysis of variance (ANOVA) and signal to noise ratio analyses are employed to investigate the influence of different welding parameters on the hardness and to obtain the optimum parameters. The results indicated that a maximum hardness of 60 Hv can be achieved through underwater FSW at the nugget zone.
10. STUDY ON ANTIFUNGAL ACTIVITY OF ALCALIGENES SPP. BY CULTURING IN RAW SUBSTRATES
Two Alcaligenes spp. (A1 and A2) were isolated from acidic soil (pH 4 to 4.5) of the battery factory in Mandalay Industrial Zone. These two bacteria showed antifungal activity against three common plant pathogenic fungi (Fusarium oxysporum, Rhizoctonia solani and Pythium sp.). Peptone based nutrient medium was used for culturing these two Alcaligenes spp. and it will not be suitable for large scale production in industry because of its high cost. So, two raw substrates such as groundnut meal cake and soy bean meal were used to study in the substitution of the peptone. According to the resulting data, the antifungal activities of two Alcaligenes spp. culturing in groundnut can compare with the activities in peptone although the activities in soy meal was not as good as that in peptone. So, the commercial production of biofungicide from Alcaligenes spp. can be considered by using substituted groundnut raw substrate.
11. THERMO ACOUSTICAL PROPERTIES OF 1,1 BIS(2,6 DICHLORO 4 HYDROXYPHENYL) CYCLOHEXANE SOLUTIONS AT ATMOSPHERIC PRESSURE
In present work we have reported thermo acoustical and thermodynamic properties of 1,1 bis(2,6 dichloro 4 hydroxyphenyl) cyclohexane (ClBC). The density, viscosity and ultrasonic speed (U) of pure solvents 1, 4 dioxane (DO), chloroform (CF), ethyl acetate (EA), tetrahydrofuran (THF) and ClBC solutions were investigated at four different temperatures 298, 303, 308 and 313K to understand the effect of solvents and temperature on molecular interactions. Various acoustical and thermodynamic parameters such as specific acoustical impedance (Z), adiabatic compressibility (Кa), intermolecular free path length (Lf), Raos molar sound function (Rm), Van der Waals constant (b), internal pressure, free volume (Vf), viscous relaxation time and classical absorption coefficient were calculated and fairly good corelationship between calculated parameters were obtained. A fairly good to excellent correlation between a given parameter and concentration is observed at all temperatures and solvent systems studied. Gibbs free energy of activation is found both concentration and temperature dependent. Both enthalpy of activation and entropy of activation are found concentration dependent. Thus, acoustical and thermodynamic parameters confirmed presence of strong molecular interactions and structure making nature of the compound.
12. BUFOTALIN PROMOTES TRAIL INDUCED APOPTOSIS IN NON-SMALL LUNG CANCER CELLS
This study investigates the effects of bufotalin, a bufodienolides compound isolated from toad venom, on sensitizing TNF related apoptosis inducing ligand (TRAIL) induced apoptosis of non small lung cancer cell lines, A549 and PC 9. Cells were treated with bufotalin in the presence and absence of TRAIL. The cells viability was observed using WST 1(4 [3 (4 iodophenyl) 2 (4 nitrophenyl) 2H 5 tetrazolio] 1, 3 benzene disulfonate) assay. The TRAIL induced apoptotic signaling proteins were examined by immunoblotting. The results showed that TRAIL alone showed potent cytotoxicity on PC 9 cells, but weakly induced the death of the A549 cells, indicating that A549 cells are a TRAIL resistance cell line and PC 9 cells are a TRAIL sensitive cell line. Bufotalin significantly enhanced death receptor 4 (DR4) induced cell death in the A549 cell line through the activation of caspase 3 and PARP 1. The combination of bufotalin with TRAIL resulted in the down regulation of Bid, c FLIP, and the up regulation of DR4, RB and p53. In contrast, TRAIL dramatically induced cell death and bufotalin has no effect on TRAIL induced PC 9 cell death. The results indicate that bufotalin sensitizes the A549 cells, but not the PC 9 cells to TRAIL induced apoptosis through DR4 induced apoptotic pathway.

16. STUDY OF REASONABLE WELL PLANNING FOR TERTIARY INFILLING IN XING6 AREA, DAQING OILFIELD
Daqing Oilfield is the most important and the biggest oil field in China, with forty five years water flooding development, the reservoir in Xing6 area is in high water cut stage of development. The scatter distribution of remaining oil and the poor development on thin and poor oil layers are present problems. After the adjustment of secondary infilling implemented in 1996, the recovery degree of low permeability and thin layers has been improved, but the development on tabulated thin reservoir (effective thickness between 0.2 to 0.5m) is still poor, especially the un tabulated reservoir (effective thickness below 0.2m). In response to the sand layers with effective thickness below 0.5m, the tertiary infilling stage is implemented. On the basis of elaborate reservoir geological description, and using the skills of comprehensive description of the remaining oil, we analyze the features of remaining oil, as well as all types of layers washing condition and adjustable sandstone thickness after secondary infilling in Xing6 area. The results indicate that the Xing6 reservoir has certain potential for tertiary infilling adjustment. In this paper, we adopt the three combinations policy, combined tertiary infilling adjustment with original well pattern, combined tertiary infilling adjustment with water flooding regime modification, and combined tertiary infilling adjustment with later tertiary oil recovery, to optimize well distribution. Through the adjustment of the well pattern, injector producer distance, well density, water flooding system, etc., the perfect water flooding regime is achieved to fully produce the remaining oil of the sand layers with effective thickness below 0.5m. The good results have been achieved in Xing6 area. After the adjustment of tertiary infilling, the Xing6 area recovery ratio increases 2.72%, the flooding control degree of tabulated thin reservoir (effective thickness between 0.2 to 0.5m) and un tabulated reservoir (effective thickness below 0.2m) increase 4.23% and 9.69%, and formed the matching tertiary infilling techniques.

Xiangrong Nie, Shenglai Yang, Hao Lei, Yong Fang, Quanzheng Ma, Can Chen, Zhipeng Qiu
CO2 as the main cause of global warming is threatening the circumstance of human being living. So the geological storage of CO2 becomes one of the hot topics. By physics simulation experiments, the feasibility study of enhance oil recovery (EOR) using CO2 is studied. The results show that CO2 can not only enhance the recovery percent, but also can be stored in reservoir effectively. CO2 can greatly increase oil recovery percent compared with water flooding. Water alternating CO2 should given priority by using CO2. In case of water alternating CO2, the optimum gas water ratio is 1 1 and the optimum plug volume is 0.1 times of pore volume (PV), earlier water alternating CO2 will makes better development effect.

Zhilin Wang, Shenglai Yang, Jichen Yu, Hao Lei, Quanzhen Ma
It is generally believed that the porosity, permeability, wettability of reservoir varies after long term water flooding. But the researches of relative permeability curve variation of reservoir after long term water flooding were rare. A laboratory unsteady state method was used to research oil water relative permeability for cores under the approximate conditions of oil reservoirs after long term water flooding, and the results were compared with those of the conventional cores. According to this comparison if the water saturation is fixed, the water phase permeability of cores after long water drive will be higher than that of conventional cores, and the conventional cores will generally be earlier in water breakthrough and faster in water cut increase than cores after long water drive, with the cores after long water drive being higher in the water free oil recovery and the ultimate oil recovery than the conventional cores. The wettability of cores after long water drive will change after oil washing, and their remaining oil saturation will somewhat in crease due to expanding internal pore surface by the remove of solid particles during oil washing.
