Microbial-induced calcite precipitation (MICP) is a novel ground improvement method to increase strength and stiffness of sand using natural biogeochemical processes. This paper describes the application of MICP in slope improvement. A strip footing was tested in a laboratory by conducting a model load test on sand slope of 1.5H: 1V. The slope was treated by injecting bacteria (S. Pasteurii) and cementation solution (CaCl2 + Urea) at 2M concentration in a grid pattern of 100 mm x 100 mm. These slopes were allowed to cure for the incubation period of 14 and 28 days. The load tests were conducted for three locations of footing on edges at a distance measured from slope crest as 0B, B and 2B. The results indicated that the bearing capacity of footing on slope increased significantly after MICP treatment. The bearing capacity of slopes cured for 28 days was found to be maximum.

The world is facing crisis due to the dwindling sources of fossil fuels. Rapid depletion of conventional energy is a matter of serious concern for the mankind. There is a necessity to find alternative fuels for different industrial needs, automobiles and aircrafts. The conventional forms of energy supply and consumption are causing serious economical as well as environmental problems. Import dependence for oil in India is about 70 percent, and is likely to increase further. If the fossil fuels are consumed at present rate it may not take much time before the oil reserves get totally exhausted. It is, therefore, imperative to search for the alternative fuels that are renewable in nature, locally grown and friendly to environm1ent. Diesel and alternative fuels like coconut oil and cotton seed oil are used as fuels. Previously efficiency of alternative fuels like coconut oil and cotton seed oil blends with diesel was tested. The blends of varying proportions of these alternative fuels and diesel are used to run the engine and significant improvements in engine performance and emission characteristics are observed.These improvements are attributed to more complete combustion of oxygenated fuel. Engine performance values such as Indicated Horse Power, Brake Horse Power, Fuel Consumption, Mechanical Efficiency, Volumetric Efficiency, Indicated Brake Thermal Efficiency and Air Fuel Ratios are determined by varying fuel injection pressure with variation of Engine loads along with different blends of oils. Even through the viscosity of the coconut oil is low and is economically friendly. Considering the thermal efficiency, the cotton seed oil blend (B50) is preferable as it is giving it is good characteristics curve.

The importance of this study is primarily to address the energy problem. The main contribution of this study, in addition to conserving energy through recovery technique, is reduction in the impact of global warming due to exhaust gas emission to the environment. The objective of the research is to recover exhaust gases energy from internal combustion engines for utilization. The experimental set-up consisted of a single cylinder, four-stroke, multi-fuel engine connected to eddy current dynamometer for loading. Thermocouple temperature sensors and transmitters were used to measure exhaust gas to calorimeter inlet temperature and exhaust gas from calorimeter outlet temperature. Exhaust gas mass flow rate and temperature measurements were used to determine the recovered energy. Recovered heat energy was 1.257% of fuel energy when the engine was operated on diesel at 1000 rpm and a torque load of 18 Nm. 3.153% of fuel energy was recovered at 1500 rpm and a torque load of 6 Nm when biodiesel was used. At a speed of 1000 rpm 22.6% and 23.004% of the thermal energy through exhaust was recovered when the engine used diesel and biodiesel at torque loads of 6 Nm and 14 Nm respectively.

This paper investigates the effects of genetic algorithm parameters on the performance of optimum structural search. The most significant of these parameters can be grouped according to their biologicallyinspired functions: population size, initial population, and crossover and mutation operators. However, since the genetic algorithms use a random search the numerical results presented in this paper show the extent to which the quality of solution depends on the choice of these parameters.

Waste Disposal in urban areas with dense population is a challenging problem for a developing country like India. Although there are other methods for waste disposal (Recycling, Composting, Incineration), it is generally accepted that landfill is the most cost effective disposal method. This has the advantage of putting useless land to reclamation. Previous studies shown that clay compacted to a permeability of less than10 -7 cm/sec form a good barrier to leachate and also cost effective. The present work in this area has two aspects viz., suitability of local soils from stability and permeability characteristics for use as landfill clay liners and study on clay-leachate interaction using soft clay as clay liner. The basic properties like Liquid limit (LL), Plastic limit (PL), Free swell index (FSI) and pH are discussed in terms of physicochemical aspect. Certain mineralogical and microstructure studies undertaken on this interaction phenomenon are also presented. It is concluded that organic chemicals presented in the leachate destroy the double layer properties of soft clay and reduce the plasticity of the soils. Formations of some new clay minerals are observed in X-ray Diffraction graphs and formation of aggregates and flocs are observed in scanning electron micrographs.

Block 1 and 2 Combined Cycle Power Plant (CCPP) Muara Tawar have 5 units gas turbine can be operated by using fuel gas. Due to limitation of fuel gas from gas company. Several gas turbine are operated using High Speed Diesel fuel (HSD) to fulfil load demand. The equipment that used for fuel gas system must have high realibility to serve in dual fuel system neither operated using fuel oil or gas without unit trip. In actual, there are several disturbances occur during change over from gas to oil, even when the plant operated using fuel oil. From the data of failure causes, one of the failure causes is valve failure. By considering the availbility of plant, in term of possibility to modify instrumentation and control system, gas turbine 1.3 was choosen as object of the study. Additional indicator in HMI can be described as follows additional pressure switch attribute at EDS-P3 using symbol K, upload program to EPROM at card 70BK06 as communication card, and the cycle time less than 1 second in both valve open or close. It indicate valve system under good condition or no maintenance action is required. Valve maintenance at gas turbine ALSTOM 13E2 in Block 1 and 2 CCPP Muara Tawar can be done by additional indicator of pressure switch and aux relay contact as feedback signal on POS 30. Therefore, no disturbances in valve system and gas turbine performance increases.
Muara Tawar第一座和第二座联合循环发电厂(CCPP)有5台燃气轮机，可以使用燃气来运行。由于燃气公司的燃气限制。一些燃气轮机使用高速柴油(HSD)来满足负荷需求。用于燃气系统的设备必须具有高的可靠性，才能在双燃料系统中运行，既不使用燃油，也不使用燃气。实际上，在从天然气到石油的转换过程中，甚至当工厂使用燃油运行时，也会发生一些干扰。从失效原因的数据来看，其中一个失效原因是阀门失效。考虑到电厂的可用性，考虑到仪表和控制系统的修改可能性，选择燃气轮机1.3作为研究对象。HMI中的附加指示器描述如下:EDS-P3附加压力开关属性，使用符号K，将程序上传到70BK06卡的EPROM作为通信卡，阀门开启或关闭的周期时间小于1秒。表示阀门系统状态良好或不需要进行维护。Muara Tawar地块1和2 CCPP ALSTOM 13E2燃气轮机的阀门维护可以通过附加压力开关指示器和辅助继电器触点作为POS 30上的反馈信号来完成。因此，阀系统无扰动，燃气轮机性能提高。
