various combustion characteristics and properties are studied while selecting a fuel for any engine. the choice of the engine and fuel are highly interrelated. vegetable oil is one obvious fuel particularly because their fuel properties are closer to diesel fuel. two important properties, the cetane number and the calorific value are similar to diesel. hence diesel engines can be operated on ve...

in this study, a numerical simulation using the cfd software, fluent, has been conducted to examine the effect of various shapes of the venturi component sections in order to find the optimum venturi specifications to increase the egr rate with minimum pressure loss at the part load operation range. the cfd results reveal that the venturi should be precisely optimized to introduce the required ...

the objective of this work was to develop a new design of an intake manifold through a 1d simulation. it is quite familiar that a duly designed intake manifold is essential for the optimal performance of an internal combustion engine. air flow inside the intake manifold is one of the important factors, which governs the engine performance and emissions. hence the flow phenomenon inside the inta...

background: trichomonas vaginalis is a parasitic protozoan with a predilection for human urogenital tract and causative agent for vaginitis, cervicitis and urethritis in females. t. vaginalis is known as a cofactor in transmission of human immunodeficiency virus and may lead to adverse outcomes in pregnant women. the goal of this study was to determine the prevalence of t. vaginalis infection i...

in order to reduce wear in gudgeon pin, bush and piston boss lubrication is done. oil used in national engine species was 10w40 with dynamic viscosity 5.5 mpa.s at 140 °c (the working temperature). in order to complete investigation the oil film hydrodynamics analysis in small end of connecting rod, a real full model engine with four cylinders has been simulated by avl excite5.1 software. in th...

Nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. Inthis research, the application of Response Surface Methodology (RSM) was highlighted to investigate the effects of biodiesel-diesel blends (B0, B20, B50 and B100), engine operating parameters (engine load and  speed) on CO2 emission of a diesel engine. The experiments were conducte...

Investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (LHR) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].The engine had different operating conditions...

BACKGROUND Trichomonas vaginalis is a parasitic protozoan which causes most common non viral sexually transmitted disease trichomoniasis. Direct microscopic examination of vaginal fluid remains the most widely used diagnostic test. Although, wet mount examination is the most cost-effective diagnostic test, but it has low sensitivity resulting in under diagnosis of the disease. Therefore, to ove...
