Abstract

Dry sliding wear performance of aluminium alloy (AA 6063) was studied by varying applied normal load, sliding velocity and varying specimen temperatures from 50 to 150 °C. The results signify that the wear increases as the load increases from 10 to 20 N, while it decreases when the sliding velocity of the specimen increases from 1 to 2 m/s at room temperature. As the temperature of the specimen increases, the wear rate increases marginally at initial stage and then increases rapidly for a constant load and velocity. The specific wear was found to be decreased when load and sliding velocity were increased. However, in the case of varying specimen temperature condition, particularly at elevated temperature of the specimen, the specific wear showed an increasing trend. Coefficient of friction (COF) was nearly stable to both load and velocity, but it is marginally vary when temperature of the specimen increases from 50 to 100 °C and it decreases rapidly from 100 to 150 °C.

Abstract

Siddha's system of medicine is the effective one to reduce the symptoms of many viral illnesses. Siddha's system of medicine in asymptomatic, mild to moderate Covid-19 Positive patients, will make them recognize its effectiveness, reduce the symptoms, and move into the traditional approach towards the deadliest pandemic disease Covid-19. The objective of this study is to evaluate the acceptance and benefit of integrative Siddha management among the mild, moderate and asymptomatic COVID patients through a feedback questionnaire in TPEC COVID Care Center, Vellore, Tamil Nadu (TPECThanthai Periyar Engineering College). 74 asymptomatic, mild to moderate Covid-19 Positive patients were observed 7 days from 14.07.2020 to 30.07.2020 in TPEC COVID Care Center, Vellore, Tamil Nadu. During this period, Siddha medicines were administrated along with Western medicine. At the end of the period, validated feedback questionnaires were used to collect information from 74 participants for evaluating the acceptance and benefit of integrative Siddha management.In the 74 patients of TPEC COVID Care Center, Vellore, 100% were taken the given Siddha drug properly. 82.4% had the most common symptoms and 52.7% had less common symptoms. 16.2% of cases developed gastric acidity and 1.3% developed mild dyspnea as an ADR. 91.8% were recommended the Siddha system to others. 93.2% reported excellent disease progress. 90.7% of Siddha doctors quoted for 'Excellent' service on covid patients. This feedback report explores the three important significance. (a) Siddha medicine having significant effectiveness (b) Siddha medicines have safety in covid-19 patients (c) overall services of Siddha doctors are appreciatable by the patients and Siddha system is recommended to others. This analysis report helps to provide the possibility of the Siddha system for further or future clinical trials.
