Present Concept

Examination of ongoing pathology in patient’s body is quite essential for a physician to calculate the estimation the dose of drug. But examination method mentioned in Ayurveda is incomplete without using the present concept of Aturaparijnana Hetu. With the help of Aturaparijnana Hetu the traditional methods of person understanding (the Dashavidha Pariksha) become more accurate and powerful. Aturaparijnaana Hetu gives standard of a person. In this way, examination method acquires the foundation; designed for grading. In short, person’s residual strength can be documented. These article is intended to highlight the research work through survey study that how can a group is identify by their respective Desha and their role in Dashavidha Pariksha. Dehabala and Doshabala are assessing by this methods.

Composite materials usage in several industrial fields is now widespread, and this leads to the necessity of overcoming issues that are still currently open. In the aeronautic industry, this is especially true for Barely Visible Impact Damage (BVID) and humidity uptake issues. BVID is the most insidious kind of impact damage, being rather common and not easily detectable. These, along with the ageing that a composite structure could face during its operative life, could be a cause of fatal failures. In this paper, the influence of water absorption on impacted specimens compressive residual strength was studied. Specimens were impacted using a modified Charpy pendulum. Two different locations were chosen for comparison: Near-Edge (NE) and Central (CI). Accelerated hygrothermal ageing was conducted on impacted and reference nonimpacted coupons, placing them in a water-filled jar at 70 °C. Compressive tests were performed in accordance with the Combined Loading Compression (CLC) test method. A Dynamic Mechanical Analysis (DMA) was performed as well. The results showed the influence of hygrothermal ageing, as expected. Nevertheless, the influence of impact location on compressive residual strength is not clearly noticeable in aged specimens, leading to the conclusion that hygrothermal ageing may have a greater effect on composite compressive strength than the analysed BVI damage.
