In this research work, the effectiveness of stainless steel sheet for the production of motor cycle exhaust muffler burn protector was investigated. Energy Dispersive X-Ray fluorescence method was used to determine the chemical composition of the stainless steel materials and exhaust muffler of the motor cycle. The stainless steel sheet was perforated and folded to frustum shape to achieve aero...

The axe kick, in Olympic style taekwondo, has been identified as the most popular scoring technique aimed to the head during full contact competition. The first purpose of this study was to identify and investigate design issues with the current World Taekwondo Federation approved chest protector. A secondary purpose was to develop a novel chest protector addressing the identified design issues...

Laparoscopic surgery is widespread and safe for the management of patients with colorectal cancer (CRC). Although the use of standard surgical techniques can prevent perioperative wound infections, surgical site infections (SSIs) remain an unresolved complication in laparoscopic-assisted colectomy. The present study investigated the ability of plastic wound protectors applied to the extraction ...

There has been a significant increase in the number of facial fractures stemming from sport activities in recent years, with the nasal bone one of the most affected structures. Researchers recommend the use of a nose protector, but there is no standardization regarding the material employed. Clinical experience has demonstrated that a combination of a flexible and rigid layer of ethylene vinyl ...

The purpose of this study was to determine if hard and soft rib protector garments have an effect on trunk kinematics and throw performance (accuracy and speed) of experienced quarterbacks during an overhand football pass. Eight quarterbacks completed 10 throws during each of three rib protector conditions (no rib, soft, hard). Protector conditions were compared using non-inferiority testing. N...

Although the design of DNA tiles has been optimised for efficient and specific self-assembly, assembly errors occur so often that applications for molecular computation remain limited. We propose the use of an enveloped tile consisting of a DXbase tile that carries a protector tile to suppress erroneous tile assembly. The design of the enveloped tile promotes the dissociation of the protector t...

OBJECTIVE A meta-analysis of randomized clinical trials (RCTs) was conducted to evaluate whether wound protectors reduce the risk of surgical site infection (SSI) after gastrointestinal and biliary tract surgery. BACKGROUND The effectiveness of impervious wound edge protectors for reduction of SSI remains unclear. METHODS A systematic review was conducted in Medline, EMBASE, and the Cochran...

Consider a network vulnerable to viral infection, where the security software can guarantee safety only to a limited part of it. We model this practical network scenario as a non-cooperative multiplayer game on a graph, with two kinds of players, a set of attackers and a protector player, representing the viruses and the system security software, respectively. Each attacker player chooses a nod...

OBJECTIVES To assess the acceptability and compliance with use of an energy-shunting hip protector in institutionalized elderly people. DESIGN AND SETTING A 6 month prospective follow-up in a Finnish nursing home. PARTICIPANTS 19 ambulatory nursing home residents with a high risk of hip fracture. MAIN OUTCOME MEASURES The proportion of the residents who were willing to use the device, the...
