This study highlights how the results from an artificial engine oil aging method compare to used samples collected a vehicle fleet. Additionally, this paper presents effect of contaminating during with synthetic fuel alternatives on physical and chemical properties artificially aged samples. A laboratory-scale thermo-oxidative experiment was conducted multiple commercially available formulated ...

The 21st century is challenging for human beings. Increased population growth, population aging, generation of new infectious agents, and natural disasters are some threatening factors for the current state of blood transfusion. However, it seems that science and technology not only could overcome these challenges but also would turn many human dreams to reality in this regard. Scientists belie...

Cachaça is a type of distilled drink from sugarcane with great economic importance. Its classification includes three types: aged, premium and extra premium. These three classifications are related to the aging time of the drink in wooden casks. Besides the aging time, it is important to know what the wood used in the barrel storage in order the properties of each drink are properly informed co...

Polypropylene (PP) has a wide range of applications in the automobile bumpers due to its many excellent properties. Mechanical properties PP for are investigated through an artificial accelerated aging test. The rules after different years normal use and test analyzed. correlation between natural artificially is also explored. It provides reference study polymers automotive applications. Result...

objectives: composite restorations must have tooth-like optical properties namely color and translucency and maintain them for a long time. this study aimed to compare the effect of accelerated artificial aging (aaa) on the translucency of three methacrylate-based composites (filtek z250, filtek z250xt and filtek z350xt) and one silorane-based composite resin (filtek p90). materials and methods...
