Abstract

Surface gravity waves play an important role in ocean engineering studies and their influence on the dynamics of the coastal zone is critical. Proper knowledge on wind-wave climatology is an area of immense interest to engineers and climate modellers. Climate change has influenced weather patterns over global oceans and at present is a matter of serious concern, as it can have long-term repercussions. There is a need to understand the recent trends in variability of windwaves for planning operations. To improve climate projections the Intergovernmental Panel on Climate Change report highlights the need and importance for wind-wave climate study. With this motivation, we study the variability of recent trends in maximum wind speed (MWS) and maximum significant wave height (MSWH) exclusively based on altimeter data for the Indian Ocean basin. We use daily data of MWS and MSWH from eight satellite missions covering a period of 21 years (1992-2012). The findings indicate that regions in the Southern Ocean (between 45°S and 55°S) experienced the largest variability in wind-wave climate. Higher MSWH resulting from increased MWS has practical implications on swell generation field that eventually cross the hemisphere influencing wind-waves elsewhere. The study also reveals the impact of wind-wave activity for the Indian Ocean basin in the past decade.

Abstract

Denture labelling is not a new concept in either prosthetic or forensic dentistry and its routine practice has been urged by forensic dentists internationally for many years. Prosthodontists are playing very important role in forensic dentistry as they are concerned with fabrication of various prosthesis which can serve as an important tool for identification. The main objective of this article is to discuss the various methods available for denture marking along with three case reports.

Keywords

Denture Labelling, Denture Identification and Denture Markings.

Abstract

The hand in the human body plays a major role in daily life, communication, social contact and basic functions such as grasping. Finger and partial finger amputations are the most frequently found forms of hand loss and trauma which lead to an impact on the psychological health, functional abilities and aesthetics of an individual. A prosthesis with good fitting, comfort and aesthetics can make the patient feel capable and whole again. This article describes a technique for fabrication of a custom made glove type finger prosthesis using silicone elastomers along with a ring for providing more retention to the prosthesis. Shade matching has been achieved by using intrinsic acrylic paints. This case report paper describes a technique to prosthetic rehabilitation of an amputated finger by fabrication of custom finger prosthesis by using silicone elastomer, which is aesthetically acceptable, comfortable to use and is cost effective with a simple approach.

Keywords

Silicone Elastomer, Finger Prosthesis, Color Matching, Retention.
