Improvement in frictional behaviour of SAE 15W-40 lubricant with the addition of graphite particles

Publication date: Available online 9 September 2019Source: Materials Today: ProceedingsAuthor(s): Vineet Sharma, Rajat Joshi, Himanshu Pant, Vipin Kumar SharmaAbstractThe present paper discusses the use of graphite particles in the lubricant for enhancing the friction properties of lubricant. Graphite particles were produced using the ball milling methods and mixed with multi-grade SAE 15W-40 lubricating oil using a magnetic stirrer and ultrasonicator. The graphite mixed lubricant was tested for its frictional behaviour using a linear reciprocating tribometer. Experiments were performed at three load values with constant stroke length and frequency. It is observed that graphite mixed lubricant resulted in reduction in coefficient of friction (COF) values. For the considered operating parameters, there is 33–36% reduction in the COF values. The overall temperature generation during the testing was also low for the graphite mixed lubricant testing.

Duplex ultrasound examination, computed tomography scans, and magnetic resonance angiography have traditionally been used as noninvasive methods to assess carotid stenosis severity. The degree of stenosis in asymptomatic patients has often been used as the main criterion to assess risk for plaque embolization and stroke. There has been an effort to find alternate methods to assess vulnerable plaques. This has included many modalities, including magnetic resonance imaging and other ultrasound techniques.

This study explores the safety and effect of acute cerebral infarction treatment by microcatheter injection of tirofiban combined with a Solitaire AB stent and/or stent implantation. Emergency cerebral angiograms showing the responsible vascular occlusion of 120 acute cerebral infarction patients who underwent emergency endovascular thrombectomy were included in the study. These patients were randomly divided into two groups using the random number table method: treatment group (n=60) that received thrombectomy (with cerebral artery stents) combined with intracerebral injection of tirofiban and control group (n=60) that on...

In this study, the trends of risk factors and macrovascular complications were examined in patients with DM in Taiwan.MethodsHealth care information and International Classification of Diseases, Ninth Revision diagnostic codes were retrieved from the Taiwan Bureau of National Health Insurance claims files between 2005 and 2014. Using these data, the number of cases and annual prevalence of diabetic macrovascular complications in individuals with DM were stratified by age and sex.ResultsThe prevalence of DM with either stroke or cardiovascular disease (CVD) showed a decreasing trend in enrolled patients with DM (p for trend
