Initially Lister used have been used (sutures, stents, paste dressings, tissue tacks and accurate coaptation of the flaps. Various methods and materials silk as a suture material, on the assumption that it was absorbable and therefore could also be used for ligatures. Later he searched most popular method. The term “suture” describes any strand of adhesives) for precise flap placement. Suturing has remained the for a more rapidly absorbable material and consequently began to material utilized to ligate blood vessels or approximate tissues. use catgut.

Master's thesis in Applied Mechanics ELIAS BLOMSTRAND MIKE DEMANT Department of Applied Mechanics Division of Solid Mechanics Chalmers University of Technology Abstract Badminton, said to be the worlds fastest ball sport, is a fairly unknown sport from a scientific point of view. There has been great progress made to get from the old wooden rackets of the 19th century to the light-weight high performance composite ones used today, but the development process is based on a trial and error method rather than on scientific knowledge. The limited amount of existing studies indicate that racket parameters like shaft stiffness, center of gravity and head geometry affect the performance of the racket greatly.

  • Comparison of Influence of Vicryl and Silk Suture Materials on Wound Healing After Third Molar Surgery- a Review
    Harshinee Chandrasekhar et al /J. Pharm. Sci. & Res. Vol. 9(12), 2017, 2426-2428 Comparison of Influence of Vicryl and Silk Suture Materials on Wound Healing After Third Molar Surgery- A Review Harshinee Chandrasekhar Undergraduate student,Saveetha Dental College, Saveetha university Dr.Sivakumar M.D.S., Senior lecturer,Department of Oral and Maxillofacial Surgery, Saveetha Dental College, Saveetha university DR.M.P.Santhosh Kumar M.D.S.,* Reader,Department of Oral and Maxillofacial Surgery, Saveetha Dental College, Saveetha university Abstract Suture materials play an important role in healing, enabling reconstruction and reassembly of tissue separated by the surgical procedure or trauma. Suture materials are used daily in oral surgery, and are considered to be substances most commonly implanted in human body. Silk has been used as biomedical suture material for centuries and it provides important clinical repair options for many applications but the disadvantage is the biocompatibility problems reported for silk obtained from contamination of residual sericin (glue-like proteins). Now-a-days, Vicryl suturing material is the commonly used material in oral surgery, because it does not allow adherence of plaque and is well suited for handling. The characteristics of these two materials are discussed in this review and it also compares the influence of these materials on wound healing after third molar surgery. Keywords-Silk suture, vicryl suture, wound healing, third molar surgery, complications, Polyglactin INTRODUCTION The main classification is based on biological properties:- Suture materials play an important role in healing of Natural Absorbable Suture material: wounds, enabling reconstruction and reassembly of tissue Catgut separated by a surgical procedure or a trauma, and at the Collagen same time facilitating and promoting healing and Cargile membrane haemostasis [1].

It is a practical guide in an area of armed conflict based on the experience of four nurses who have managed independent hospitals set up by the International Committee of the Red Cross. It addresses specific problems associated with setting up a hospital in a difficult and potentially dangerous environment. It provides a framework for the administration of such a hospital.

See the Zanzibar Tribal Art web site for an explanation and diagram of the life cycle of the various silkworms . YouTube video clip of Silk factory in Beijing Natural silk is one of the strongest textile fibres, which are accounted for by the stretched-out molecular form. Silk (78% protein) is much stiffer than wool in spite of both being proteins made from amino acids chains. Silk fibres have fine draping qualities and are naturally crease-resistant and bring about a warm feel to the skin. Of the 3-4000 metres of fibre in a cocoon, laid out as a figure of eight by the movement of the head of the pupae, less that one third is generally usable with much of the remainder being processed separately. Silk emitted by the silkworm consists of two main proteins, sericin and fibroin, fibroin being the structural center of the silk, and serecin being the sticky material surrounding it. Fibroin is largely made up of the amino acids Gly-Ser-Gly-Ala-Gly-Ala and forms beta pleated sheets, β-keratin. 1 of 9 20/10/2011 08:28 PM Unit - Chemistry of Textiles: Animal Fibres file:///C:/WWW/Courses/CHEM2402/Textiles/Animal_Fibres.html R = H, glycine; R = CH , alanine; R = CH OH, serine 3 2 Hydrogen bonds form between chains, and side chains form above and below the plane of the hydrogen bond network.

Abstract: Spider web is sparkling in sunlight can be a truly beautiful sight. The strength-to-weight ratio of material is remarkable. Cobweb is used as material which is used to synthesize silver nanoparticles. Cobweb was subjected to hydrolysis using a base and web extract was prepared to form a reaction mixture of 10:50 (Extract:AgNO3) solution and silver nanoparticles(SNPs) are synthesized which were dark brown in colour and characterization was done using SEM. Biodegradable sutures were collected and immersed in SNPs of spider web extract and tested for its tensile strength, antibacterial activity with Streptococcus mutants MTCC497 and Staphylococcus aureus ATCC 29213 was evaluated. Characterization of silver ions by SEM analysis showed that particles were rod shaped and size was observed to be less than 180nm. Tensile strength of two different biodegradable sutures were tested which previously showed good tensile strength when they were immersed in SNPs of spider web extract and tested for tensile strength they showed modulus of elasticity. Two sutures broke in a brittle manner, as curve is linear until it breaks or fractures there is no bending observed a thigh loads which concludes that there is no permanent change in original shape during this test and showed no ductility.

    DESIGNING AND FABRICATION OF RACKET TEST RIG. SURAJ s/o VIJANATHAN Report submitted in partial fulfillment of the requirements for the award of Diploma of Mechanical Engineering Faculty of Mechanical Engineering UNIVERSITI MALAYSIA PAHANG JUNE 2013 vi ABSTRACT This thesis deals with the designing and fabrication of racket test rig. Test rig is a useful device as it is an apparatus used for assessing the performance of a piece of mechanical equipment. The main objective of this final year project is to design and fabricate a racket test rig for further study of the performance of a racket. This thesis describes the methods of designing and fabricating the mechanical part of the test rig. There are many steps taken to design and fabricate the mechanical parts of this test rig. The structural three-dimensional solid modeling of the test rig was developed by using the SolidWorks engineering drawing software. The fabrication process also undergoes many steps such as material marking, cutting, drilling, welding, milling, turning, grinding and finishing of the test rig by painting. The results of the testing of the performance of racket and how far the shuttlecock can reach with certain applied force and angle on the racket also discussed in this thesis. vii ABSTRAK Tesis ini membincangkan tentang mereka bentuk dan fabrikasi pelantar ujian raket.
