Present paper predicts fatigue life and crack growth behaviour of Al 2024-T351 friction stir welded joint by boundary element method, using professional software package FRANC3D. Crack propagation is analyzed for residual stress and stress relaxation in different friction stir welding (FSW) regimes under cyclic loads. Linear elastic fracture mechanics model is applied and simulated parameters are verified with analytical and experimental observations.

Present work highlights an experimental investigation to monitor vibration condition of boiler feed pump (BFP) unit, which is a part of BFP train of a large utility thermal power plant. Displacement and velocity were measured along horizontal, vertical and axial directions. Based on signature analysis, causes for excessive vibrations were diagnosed. Remedial measures were applied to ensure safer and fault free operation of BFP unit.

Amorphous and crystalline phases of zirconium(IV) phosphate of the class of tetravalent metal acid (tma) salt have been synthesized by sol-gel method. These materials have been characterized for elemental analysis (ICP-AES), thermal analysis (TGA), X-ray analysis, surface area (BET method) and FTIR spectroscopy. Exchangeable protons, contained in structural hydroxyl groups, indicate good potential for tma salts to be investigated as supports in heterogenised homogeneous catalysis. Pd(II) and Ru(III) has been exchanged onto amorphous and crystalline zirconium phosphate by ion exchange technique and catalytic activity investigated in some hydrogenation reactions

A portable dissolved oxygen (DO) meter based oxalate biosensor has been constructed by mounting a polyvinyl chloride (PVC) membrane bound sorghum leaf oxalate oxidase on sensing part of combined electrode of an aqualytic DO meter. Biosensor showed optimum activity within 10-12 s at pH 5.0 and 30C. A linear relationship was observed between oxalate conc. and O2 consumption [1.0-10 M (low conc. range), 0.1-1.0 mM (high conc. range)]. Biosensor gave mean value of oxalic acid in urine [22.5 mg/l in males (n=6) and 19.3 mg/l in females (n=6)], and in serum [3.2M/l in males (n=6) and 2.9 M/l in females (n=6)]. Biosensor is unaffected by physiological concentrations of Cl- and NO3-.

This study presents deodorizer (DO) distillate as a cheaper source of fatty acid to prepare alkyd resins. DO distillate-based alkyd resins provide encouraging film properties, except for color and clarity of resins. Thus, DO distillate based fatty acids are being explored as raw materials for alkyd resins in architectural coating applications.

In this paper, bitumen is modified with crumb rubber (CR). Changes in rheological properties of 60/70 and 80/100 grades bitumen modified with CR have been studied for rheological properties using Dynamic Shear Rheometer (SR5 Ashphalt Rheometer). CR improves complex modulus and elastic response of bitumen at high temperatures.

Usability evaluation of three of the most commonly used safety syringe types conducted in this study is through-push retract breakable safety syringe, rotary plunger retractable safety syringe and release-ring breakable safety syringe. By administering Safety Feature Evaluation Form (SFEF) and Focus Group Interviews on six professional nurses with an average professional experience over 11 years, usability problems with three types of safety syringe are found out. Six design principles have been ascertained and applied in development of a new safety syringe design, with input from a number of designers, nursing professionals and occupational safety technicians. New safety syringe significantly outperformed existing safety syringes on all evaluation indices.

Liquid liquid extraction of phenol from simulated sebacic acid wastewater

Phenol was extracted from sebacic acid wastewater (SAWW) using liquid-liquid extraction in batch as well as serial modes by applying different solvent: SAWW (1:250 - 5:250, v/v). Alcohols (1-hexanol, 1-heptanol, and 1-octanol), castor oil and Aliquat-336 were used for phenol extraction. In a typical extraction experiment involving shaking and allowing for phase separation, phenol (75-96%) can be extracted with different solvents using solvent-wastewater ratio (5:250 v/v). Generally, extraction (%) increased with solvent ratio; however, chain length of alcohols did not affect extractability of phenol much. Best extraction of phenol occurred into Aliquat 336.
