Biodiesel is a mixture of mono-alkyl esters of long chain fatty acids derived from a renewable lipid feedstock. It can be used as an alternative fuel as the fossil fuels are getting depleted day by day. Moreover the use of biodiesel leads to the substantial reduction in the pollution caused by PM, HC, CO etc. This paper consists of the production of biodiesel from waste cooking oil using alkaline catalysts NAOH and KOH and cosolvent acetone in the presence of methanol. Waste cooking oil is used because of its high oil content and abundant availability. This method used is co-solvent method.

The development of the city can support the land use changes, resulting in the growth of the number of occupants in sub-urban areas, if it is incommensurate to the increase of structure and infrastructure of transportation can cause the congestion in the arterial road. The aims of this research is to analyze the characteristic of land-use changes of the construction of ring roads in terms of change areas and price and value of land and to analyze the influence of the development of ring roads to the development of urban structure. This research uses primary data and secondary data. Primary data derived from the interviews and field observations, secondary data derived from relevant government agencies and google earth. Data were analyzed by qualitative descriptive and spatial analysis. The location of the research was conducted in Masamba Sub-district of North Luwu Regency, which is the developmental spaces along the ring roads and settlements that have direct access to the ring road. The results of the analysis indicate that the largest type of land-use that changed into settlements after the construction of the ring road is irrigated agricultural land and mixed plantation land. The construction of the ring road does not affect the city's developmental structure, as the fact is that the city of Masamba is a monocentric city in that it has only one service center which also serves as the center of the city.

The purpose of this paper is to develop a multiple regression model for measuring the miles per gallon (Efficiency) by using different independent variables. How much the efficiency in terms of miles per gallon is dependent on engine displacement, horsepower, vehicle weight, model year, number of cylinders, and filters? Which is the most important variable for increasing the efficiency of automobiles? The answers of these questions are the objectives of this paper. The results indicate that model year has positive effect on efficiency of vehicle while horse power, vehicle weight, and filters have negative impact on vehicle's efficiency. Results also specify that vehicle weight has the maximum impact on miles per gallon while horsepower has the minimum impact.

Open dumping is the most common method of solid waste disposal in many developing countries including urban areas. Appropriate landfill site selection is important to minimize negative impacts associated with open dump sites. Landfill siting is an extremely difficult task to accomplish due to strong public opposition and regulations. Developing countries do not have a systematic process for landfill site selection and hence unsuccessful landfill sitting leading to environmental degradation is typically the result especially in the developing world. Selection criteria include engineering, environmental and economic criteria. Geographical Information System(GIS) is a framework for storage, maintenance, management and analysis of geographical data and it has beendesigned for working with data that has spatial and descriptive dependency.No site selection study focusingon waste disposal has been performed in Bareilly town of Uttar Pradesh, India , which is located at 250 Km East of Delhiand have a population of over 9.5 lakh people and total waste production ofapprox.129813Metric tons per year. This study hasbeen done using Guidelines for Selection of site on different factors in which criteria such as distance from residential areas,distance from roads, land use, distance from ground water, distance from faults, geology, distance from sensitiveecosystems, etc. were used and after data geo referencing, the weighting of the criteria and adjusting them with the geographical features of the area, data overlaid and finally three locations proposed for landfill were introduced in Bareilly town. Among the proposed areas, one was selected as the best location according to thehypotheses. The obtained results of this study may be helpful for policy makers of Bareilly town.Data were collected from Bareilly district, India

In High Voltage (HV) electrical power systems, variety of materials (solid, liquid and gaseous) is used for insulation purpose to protect the incipient failure in Current Transformers. Most of insulating materials are not perfect in all respect and contains always some impurities. The presence of air bubble is one of such impurities in insulating materials and highly undesirable for such type of insulation which causes a local weak zone inside the insulator. Due to the high voltage stress the weak zone inside the insulator causes the partial discharge (PD) and finally the insulation properties of such materials is enormously degrades its quality. In this work, the simulation of PD activity due to presence of a small cylindrical void inside the solid insulation material of high voltage power equipment is analyzed with the MATLAB Simulink platform.

In this paper, the working principles, the dynamic performance, and the static characteristics of full car interconnected air suspension are investigated and verified using established real physical test benches and simulations. Also, the physical and mathematical models of the suspension are established to help study the vehicle‟s roll, pitch, bounce and other relevant motions. PID and Fuzzy controllers are built using matlab/simulink to simulate and control the body vertical height adjustment of the interconnected air suspension. Two two-dimensional fuzzy controllers are applied respectively to control the front and rear air springs. To improve height adjustment precision, a target height of 20 mm is used as input to the front controller; while the actual body height in front air spring is used as an input to the rear controller. The results of the simulation clearly demonstrate that compared with the open-loop switch control, PID and fuzzy controllers are found to effectively suppress the overshoot during the process of body height adjustment. Again, by setting the front wheels as the target height, the designed controllers quickly and accurately adjust body height to the target height and significantly stabilized and improved the performance of the system as compared to the open-loop switch control.

In this work aluminium 7075 as matrix and silicon carbide and fly ash as reinforcements has been used. The %wt of reinforcement are varied to study the difference in aluminium property. Following are the samples are aluminium 7075 as 100%, aluminium 7075 90% + 10% SiC, and aluminium 7075 90% + 10% fly ash. The materials are obtained by stir casting technique. During casting 300 grams of aluminium has been taken as sample 1. 270grams of aluminium has been taken with 30grams of SiC as sample 2. The third sample is the mixture of 270grams of aluminium with 30grams of fly ash. Then the materials are made in the form of cylindrical rod of 30mm diameter and max length of 70mm. The composites are analysed for the mechanical study and the results are obtained based on hardness and the work has been extended to study the micro structure of the specimen by SEM analysis and Chemical Conformation.

During the past decade, holistic efforts by academia, industries, and regulatory bodies have resulted in a paradigm shift in the area of cellulose nanomaterials for materials applications. In an effort to reduce the dependence on petroleum-based packaging materials and coatings, groups are employing advanced nano understanding to manufacture materials that can potentially replace these materials. In effect, environmental concerns and resource availability will become the main factors driving the market demand for these products. This review focuses on the properties of cellulose-based nanomaterials and the possible use of these materials in niche applications. The review covers both partially and fully biodegradable inventions covered in the past 10 years (2006-2016) in the literature. Also, where data is available, environmental footprint and cost analysis of these products are presented.
