Abstract: Theoretical thermohydraulic performance analysis of a compact heat exchanger, type finned flat tube, used in automotive radiators is performed in based-water nanofluids. The theory of effectiveness (ε-NTU), and experimental data for water flow, are used for comparison. The oxides used in the research are CuO (copper oxide) and Al2O3 (aluminum oxide). Results were obtained for air and water outlet temperatures, heat transfer rate, the pressure drop in finned channels and tubes, as a function of the volume fraction of the oxides. It has been shown that there is an effective improvement in heat exchange and little influence on total pressure drop when using oxides in volume fractions ranging from 0.01 to 0.05, and when Newtonian......

Abstract: Concrete has been developed in several ways to avoid environmental contamination and improve the quality and properties of concrete by replacing some cement with products from other industrial processes such as pozzolanic materials, including nano-silica (NS). The aim was to improve the concrete properties by filling the spaces between the cement particles, resulting in more dense and stronger concrete by using an ultrasonic device to prevent the nano-silica particles from agglomeration and to ensure their dispersion when the mixture was moistened with water. The effect of partial replacement of cement by nano-silica (NS) was studied by making several concrete mixtures with multiple ratios of nano-silica (NS), the ideal ratio was when using 1% nano-silica (NS) which increased the compressive strength.........

Abstract: Shot Blasting machine use a various hanger during machining of various process, in this work its essential to increase production rate in current industry. For this its required to increase hanger capacity for the various castings used in the industry. To increase hanger capacity form 16 number of casting to 48 numbers of casting,soits required to re-designed the hanger such a way that its capacityup to 300Kg of short blasting machine.

Abstract: Green concrete is a new, environmentally friendly material compatible with "sustainable development." It has high strength, durability, plant similarity, and environmental friendliness. It is a concrete manifestation of development policy aimed at creating a conservation-minded society and an environmentally friendly society. With the addition of minerals, recycled aggregates, permeability, and green concrete, it can achieve the sustainable and environmentally friendly use of concrete, with the goal of improving resource use, protecting the environment to achieve sustainable development of resources..

Key words: green concrete; saving resources; improving the environment; environmental protection; sustainable development.

Abstract: Experimental testing has been used to assess the strength and deformations of reinforced concrete structures in serviceability and ultimate limit state as well as to validate finite element codes.A full-field defor-mation measurement system based on digital photogrammetry and particle image velocimetry (PIV) was pro-posed and used in an experimental study. An examination of conventional measuring methods has established the potential of using this approach. The output of the technique compared well with the results obtained from conventional measuring instruments. The proposed deformation measurement system provided detailed defor-mation data and could be used

Abstract: Many buildings in the present days have irregular shapes in both elevation and plan. Past earthquake studies show that buildings suffer severe destruction during earthquakes due to torsional irregularity.When and how to consider torsion effects is depended on the criterion andrelative restrictions for torsional irregularity. Relationship between the degree of irregularity and the change in behavior could developed which allows guidance as to a) When the effect of structural irregularity can be neglect, andb) The change in demands for different degrees of structural irregularity. Provisions in different earthquake codes about torsional irregularity are presented. This study was initiated to define the effect of different degrees of irregularity on structures designed for earthquake by investigation torsional irregularity behavior of different irregular structures using simplified analysis.....

Abstract: The present investigation is aimed at assessing the concentration of heavy metal ions along the stretches of Brahmani river basin. Fifteen samples were collected along the stretches of Brahmani basin during the period 2000 to 2015. The purpose of this study was to estimate nine heavy metals (Cu, Zn, Cd, Pb, Hg, Fe, As, Ni and Cr) in the surface water of the BrahmaniRiver, one of the most important rivers in Odisha, India. In the selected research area, the Brahmani River is receiving the domestic, industrial, and municipal waste waters/effluents all along its course. All in all, the ascendancy of the analyzed heavy metals in the surface water of Brahmani followed the sequence: Cu>Ni>Pb>Cr>As>Fe>Zn>Hg>Cd. My findings highlighted the deterioration of water quality in the rivers due to industrialization, mining and human activities.......

Abstract: It is rightly spoken "Climate change eclipses the planet earth". The issue is so predominant now, it gradually restricting our social life, peace and harmony. Number of natural calamities like flood, cyclone, drought, severe heat and cold wave, rising of sea level, melting of snow etc is some of the ready effects directly felt in different parts of the globe. The cause may be many beginning from urbanization to modern life style. But sometimes these may be part of our growth. So there may be trade off or compromise between growth and balance with nature. The study may be a small step towards recognizing the arrival of climate change and its impact on particularly agriculture, as our state largely.......
