  • Entransy Loss and its Application to Atkinson Cycle Performance Evaluation

    Based on the concept of the entransy which characterizes heat transfer ability, a new Atkinson cycle
    performance evaluation criterion termed the entransy loss is established. Our analysis shows that the maximum
    entransy loss leads to the maximum output ...  more
  • Behaviour of Steel Fibre Reinforced Concrete Beam under Cyclic Loading

    This paper describes the influence of steel fibre distribution on the ultimate strength of concrete
    beams. An experimental & analytical investigation of the behaviour of concrete beams reinforced with
    conventional steel bars and steel fibres under cycli...  more
  • Investigations on the Effect of Tool Types on the Mechanical Properties of Friction Stir Processed AZ31B Magnesium Alloy

    he present study investigates the effect of tool shoulder profile on the mechanical properties of
    friction stir processed AZ31B magnesium alloy The chosen process parameters are tool rotational speed and
    feed rate. The experiments were conducted with 3 ...  more
  • Formation Evaluation of well in order to find very perspective gas and oil in east of Kalimantan area by using mud logging servi

    ABSTRACT : Geological modeling is not an objective in itself. It may have different purposes such as IGIP, validating well locations, optimizing well trajectory reservoir studies and constraining geological models for production forecast. Geological mo...
  • Studies on Enzymatic Characteristics of select Cultures for Preparation of Beneficial Microbial Consortium for Composting of Mun

    The usual composting methods employed today involve use of native micro flora, less attention was giventowards use of cultural amendments or microbial consortium for composting of the solid waste. Thisinvestigation is directed towards developing a micr...
  • Equilibrium, kinetic and thermodynamic studies for adsorption of Reactive dyes onto activated Guava leaf powder

    Due to excessive consumption of reactive dyes, the textile industrial wastewater having high quantity of these contaminants causes pollution problems. Adsorption is a efficient method for removal of dyes and other contaminations using natural adsorbent...
  • Adsorption of Crystal Violet Dye onto Tamarind Seed Powder

    The present investigation describes adsorption of crystal violet dye from its aqueous solution onto tamarind (Tamarindus indica) fruit shell powder. Initial concentration, agitation speed and pH with various temperature have been studied, in which pH w...
  • Treatment of Textile Wastewater by Adsorption and Coagulation

    The composite of wastewater treatment was carried out using activated charcoal as adsorbent to remove COD, BOD, color in which various parameters like adsorbent dose, contact duration, temperature and agitator speed were considered. The adsorbent behav...
  • Fixed bed column adsorption of Acid Yellow17 dye onto Tamarind Seed Powder

    The intention of this study was to explore the efficacy and feasibility for Acid Yellow 17 adsorption onto fixed bed column of Tamarind Seed Powder. The effect of various parameters like flow rate, initial concentration of dye, bed height, and pH were ...
  • Comparison of Natural Materials for Colour Removal from Textile Effluent

    The comparative studies of three natural materials i.e. bentolite, zeoliteand fuller's earth for colour removal from textile waste water has beeninvestigated, in which zeolite is found to be most effective among thesenatural materials. Various paramete...
