Abstract:Natural soils are prominent material for construction activities. Red soils are widely distributed in north coastal districts of Andhra Pradesh, which are strong in dry conditions and compressed under saturated conditions. Presence of non-plastic fines and honey combing structure make the soils poor with respect to strength. In this aspect industrial wastes can be used in place of these collapsible soils. Red mud is an industrial waste from aluminum industry which can be an alternative to the soils. In the present investigations. In this aspect Red mud is one such alternative for its use in civil engineering infrastructure. In the present work characterization of Red mud is made by performing............

Abstract:Climate change will have large impact on water resources and its predictions are fraught with uncertainties all over the world. It affects the globe and hydrological cycle. It also affects the surface and subsurface water availability. These changes have being increasing the vulnerabilities of ecosystem and of human society. This paper presents an overview upon global impacts on hydrology and water resources as consequence of climate change. It explains how climate change has affected water resource variability in the past and how climate leads to rapid changes at present and future which affects the sustainable development in different parts in the world. It also explains about the effect of global warming due to the emission of green house gases. And the relation between climate change and water resource.

Abstract:Axial forces in columns caused by gravity loadings are usually estimated for initial design using tributary area method. However, this method does not consider the axial deformations in columns nor the flexural rigidities of floors. Columns subjected to high axial loads are expected to deform axially which certainly would affect the distribution of forces to columns. Moreover, floors subjected to vertical loads are expected to bend or to change in curvature. While determining axial forces in columns using tributary area method are only governed by location of columns, actual distribution is governed by axial stiffnesses of columns and flexural rigidities (or slab thickness). This study aims at giving more insights on who forces are being transmitted to columns from slabs. Analytical...........

Abstract:Welding is one of the main activities of the construction of process plants and one observes the use of several indicators in the monitoring of its productivity. In this article, the behavior of the welding productivity of ASTM A-36 steel are evaluated with the Cored Wire (FCAW) process using the E71T-1C/M electrode and two shielding gases: ArC-25 (75% Argon and 25% CO2) and ArC-40 (60% Argon and 40% CO2). The specimens were welded with procedures that met the requirements of AWS D1.1 [37] and the welding consumables used were approved in the qualification tests of AWS A5.36M / A5.36 (2012). In this evaluation, the following indicators were employed: Melt-off Rate, Deposition Rate, Operating Factor, Deposition Efficiency and Welding Productivity. In view.........

Abstract:设施布局设计对manuf产生重大影响acturing cycle time hence throughput rate. Its critical objective is to minimize material handling thus decrease manufacturing cycle time and increase throughput rate resulting to improved productivity. The low productivity recorded by Kenyan leather tanneries can be attributed to poor plant layout as the major factor. This paper explores the impact of poor plant layout on manufacturing cycle time hence throughput rate based on a case study of a tannery situated in Central Kenya. Cycle time and throughput analysis are employed in this research. The manufacturing cycle time was found to be 19 days, which exceeds the standard time by 4 days. 17.42% of the manufacturing cycle time consisted of Non Value Adding........

Abstract:制动技术转换动能energy of an automobile into mechanical energy, which must dissolute in the form of heat A brake disc usually made of cast iron or ceramic composites, is attached to the wheel. Rubbing material in the form of brake pads is enforced mechanically, hydraulically, pneumatically or electromagnetically in opposition to both sides of the disc and prevents the wheel to rotate. The current study essentially deals with the modeling and analyzing ventilated disc brake by solid works and ANSYS. Finite element (FE) models of the brake-disc are shaped with solid works and simulated using ANSYS which is based on the finite element method (FEM). This study Thermal analysis is done so as to get the strength of the disc brake. The design is found and in thermal analysis, heat flow rates, and heat fluxes are considered by varying the dissimilar cross sections and materials of the disc brake rotor.

Abstract:One of the significant problem nowadays is availability of conventional construction material for the road construction which is the major scarcity the world facing these days, where series of waste material are abundantly available from many sources which are being laid as waste, while these are increasing, along with continuous spreading of urbanization along with industrialization. GGBS & Fly Ash are few of the forms of waste material which are available enormous and at a free of cost in most of the areas and is one of the top most waste products from Steel Plant and coal burning in thermal power stations causing severe health, environmental and disposal problem. In order to ensure a sustainable waste management, we need to predict its properties and should be ready to specify its utilization and a study need to be conducted to investigate the possibility of using waste materials in place of conventional material............

Abstract:Matang Hanau is an irrigated swamp area located in Lampihong District, Balangan Regency this will be developed into a swamp irrigation area. The area is inhabited by transmigration community with oil palm gardening as their livelihood. The plantations products obtained were unsatisfactory because the land was often flooded due to flooding that often occurs during the rainy season.The transmigration community is also challenged with the clean water problem for their daily needs.The community must fulfill their need for drinking water by buying from outside the transmigration area.Whereas bathing and washing, they use water in the existing channel of the swamp irrigation. On channels where people use the water, there are cages of chicken and cattle farms, so that the water used by the community has been polluted by the waste of chicken and cattle farms. Along with the use of water in these channels, health problem such asitchiness arises............

Abstract:我n recent years with the advancement of thermo-electric materials, direct conversion of heat energy into electrical energy becomes possible. Thermoelectric technology is used for recovering heat energy loses from engine exhaust gases. The power generated by thermoelectric technology is called as thermoelectric power. In thermo-electric power generation an exhaust heat exchanger is used for recovering exhaust heat and a thermo-electric module is used for converting heat into electricity. The present research was aimed to optimize the design of exhaust heat exchanger by removing internal fins and changing the cross-sectional area of heat exchanger to overcome problem of pressure drop. The designs of exhaust heat exchangers considered in the previous research works recovered maximum heat from the exhaust of an engine However problem of pressure drop or back pressure was observed effecting engine performance and working.............

Abstract:Warm mix asphalt (WMA) technology gaining popularity in recent period, which are broadly studied and gradually applied into the industries in past years. Warm Mix Asphalts (WMA) is modified Hot Mix Asphalt (HMA) which is produced, laid and compacted at temperature which is lower than conventional Hot Mix Asphalt. Warm Mix Asphalt is produced by mixing chemical additives to the conventional mix to improve the pavement performance. In this study an attempt is made to compare the mix design, drain down and moisture-induced damage properties of Warm Mix Asphalt produced with the chemical additive (Zycotherm and Sasobit) and Hot Mix Asphalt for Stone Matrix Asphalt.............
