A few distinct feed mechanisms can be found in sewing machines. The mechanism that feeds the material into the machine differs in each machine. In lock stitch sewing machines, the mechanism known as the drop feed is the one that is utilized the majority of the time. Its construction includes one presser foot, one throat plate, and one feed dog. Different types of feed dogs can be used in the drop feed mechanism to achieve the desired level of customization. In this study, modification-1, modification-2, and modification-3 were created in an industrial lock stitch machine using feed dogs with 18, 21, and 30 teeth, respectively. These numbers correspond to the number of teeth on the feed dogs. The quality of the seams, such as the seams on garments, was analyzed after each modification of the feed mechanism performed on seams made of the same fabric (Denim fabric). We took measurements of the seam's strength and efficiency as well as its puckering and slippage. It was discovered that the seam quality of garments constructed using modification-1 (one) is superior to that of garments constructed using the other two modifications using the same fabric. Therefore, to finish a specific garment accurately, it is necessary to select the appropriate sewing machine and ensure that it has the ideal feed mechanism.

This paper discusses designing an open source software based library discovery system for full-text ETD retrieval on the basis of a cataloguing framework developed by using available global standards and best practices in the domain of theses cataloguing. The purpose of this prototype framework is to provide a single-window search and retrieval system for end users for discovering ETD at metadata level and at full-text level. The prototype framework is based on three-layer architecture with Koha ILS as backend metadata provider, Apache-Tika as full-text extractor and VuFind as discovery system. A MARC-21 bibliographic format, especially designed to handle TDs, is working as data handler mechanism in Koha ILS and the harvester of VuFind is tuned to fetch bibliographic data related to ETD in marcxml format. The user interface of VuFind is also configured to support accessing ETDs from global-scale services like NDLTD, OATD, IndCat, ShodhGanga etc. apart from the local level ETD collection in order to provide an all-in-one search interface for users.

Presents a method of metadata harvesting from different Open Archives Initiative-Protocol for Metadata Harvesting compliant institutional digital repositories containing electronic theses and dissertations. Â Reports designing of a prototype union catalogue of electronic theses and dissertations as a single-window search interface to facilitate retrieval of electronic theses and dissertations on global scale. The purpose of this union catalogue is to build an easy-to-use search service through automatic record harvesting for providing access to databases of worldwide electronic theses and dissertations.
