Engine oil or lubricating oil has a major effect on the engine life and the proper operation of any engine. Changing the engine oil before it is due increases a customer’s cost. The lubricating oil in every engine performs many functions such as reducing ... see more

Carbonation is one of the factors that can influence the chlorides transport. Despite the combined action of chlorides and carbonation being a reality, there is no consensus on the effect of this coupled deterioration on chloride transport. Accelerated te... see more

The objective of this study was to investigate the keeping quality of commercial virgin coconut oil (VCO) and toidentify the probable cause of its quality deterioration. Fourteen brands of commercial VCO and a fresh prepared VCO were used. Sensory evaluat... see more

This study focuses on identical parallel machine scheduling of jobs with deteriorating processing times and rate-modifying activities. We consider non linearly increasing processing times of jobs based on their position assignment. Rate modifying activiti... see more

The deterioration characteristics of cement-limestone powder paste under compound erosion solution were studied in this paper by determining the compressive and flexural strength of pastes, the hydration products and SEM micrographs. The results indicate ... see more

All parts of a car frame and body are subject to a variable degree to corrosion deterioration but their most problematic part is a body bolster. The work on technical diagnosing of cars, operated more than 22 years, has given the chance to gain an impress... see more

Home made halide sensors based on silver sulphide-silver halide have been prepared and successfully employed for the determination of iodide, bromide and chlorides ions in solutions. These ion sensors showed a Nernstian response in the concentration range... see more

The paper studies a periodic review inventory model with no shortages and different demand rates during pre- and post- deterioration periods . Deterioration of units start after a fixed time interval, and the deterioration rate is time dependent. The mode... see more

In order to obtain a deeper understanding of the regenerative cooling process of scramjet engines, in this paper, a numerical investigation on the supercritical convective heat transfer of n-decane in horizontal circular tubes was conducted, based on a co... see more
