The utilization of agricultural machinery represents the main aspect contributing to total energy input in system. trials were achieved using five tractor speeds(3.6, 5.4, 7.2, 9.0 and 10.8 km/hr) tillage depths(10, 15, 20, 25 30 cm) determine implement speed at different depths for 3-bottom disc plough, spring tine cultivator offset harrow on a clay loam soil. design experiment used two factor...

This paper is concerned with the statistical model development issues, necessary for rapid estimation of the rotor sizing for single main rotor helicopters at the preliminary design stage. However, Central Composite Design (CCD) method, simulation-based data collection, linear regression analysis, mathematical modelsdevelopmentand validations through the analysis of variance (ANOVA) were perfor...

Metal matrix composites, in particular, Aluminium Matrix Composites are gaining increasing attention for applications in aerospace, defence and automobile industries. The use of nonconventional machining techniques in shaping aluminum metal matrix composites has generated considerable interest as the manufacturing of complicated contours such as dies. Electrical discharge machining (EDM) appear...

Abstract The production of biodiesel from dairy effluent scum using calcined egg shell as the transesterification catalyst has been explored. Eggshell powder was at 900 °C for 3 h and used catalyst. influence methanol-oil molar ratio, concentration reaction temperature were studied Response Surface Methodology employing a Central Composite Rotatable Design. An empirical model that relates yield...

Experiments were conducted to develop low-fat soft dough biscuits using carbohydrate-based fat replacers (maltodextrin and guar gum). A central composite rotatable design was used to optimise the level of sugar 24-36%, composite fat (fat 10.5-24.5%, maltodextrin 10.4-24%, and guar gum 0.1-0.5%), ammonium bicarbonate 0.5-2.5%, and water 20-24% for production of low-fat biscuits. Diameter (P < 0....

The effect of in vitro gastrointestinal digestion on the release microencapsulated phenolic compounds was evaluated through an optimized spray drying process. A stock extract oregano developed and a dryer following central composite rotatable design, controlling variables, inlet temperature (111.7-168.2°C), percentage wall material (5.8-34.1%). Optimum conditions for were decided based differen...
