a comparison of physical properties of glass fibre epoxy composites produced by wet lay up with Autoclave consolidation and resin transfer moulding
Composites Part A-applied Science and Manufacturing, 1998Co-Authors: D Abraham, S Matthews, R. McilhaggerAbstract:Comparisons are reported for composite samples of similar resin and fibre systems which were processed using the wet lay-up with Autoclave consolidation and resin transfer moulding (RTM) by vacuum impregnation. Similar degrees of cure were obtained for laminates using the two methods of processing and the arising thermal and physical properties (tensile, flexural, interlaminar shear strength (ILSS), void content and thickness variation) were measured. The fibre dominated properties (i.e. flexural and tensile strength) were found to be higher for the Autoclaved samples due to the higher volume fraction arising from the superior compaction pressure, although when normalised on the basis of fibre volume fraction the results were similar. The matrix dominated ILSS values were higher for the RTM samples and this was attributed to improved wetting, reduced void content and a slightly lower degree of cure. Thermal analysis also indicated that the Autoclaved (60% glass fibre by volume) composite attained a slightly higher glass transition temperature than that achieved by RTM (50% fibre by volume) for similar cure times and cure temperatures. The significance of the results in an industrial context is discussed.

Autoclaved rice the textural property and its relation to starch leaching and the molecular structure of leached starch
Food Chemistry, 2019Co-Authors: Hongyan Li, Lu Yu, Wenwen Yu, Haiteng Li, Robert G GilbertAbstract:Abstract Autoclave cooking is used to produce “convenience” rice. In this study, autoclaving effects on sensory properties are investigated, and mechanistic explanations in terms of the underlying molecular structure are explored by analyzing this structure by size-exclusion chromatography and fitting the results with models based on biosynthetic processes. Compared to steam cooking, autoclaving produces stickier texture, and slightly affects hardness. It is found that molecular sizes of leached starch of both Autoclaved and steam cooked rice are similar, but significantly smaller than that of the parent grain starch; model fitting parameters of leached amylopectin and amylose structures between Autoclaved rice and steam cooked rice display no large variations. The amount of leached amylopectin (an important texture-controlling parameter) of Autoclaved rice is higher than that of steam cooked rice. Correlation analysis indicates that, compared to steam-cooked rice, the stickier texture of Autoclaved rice is caused by more amylopectin leaching during autoclaving.

Using failure mode and effects analysis improve supply efficiency central vacuum Autoclave indeed correct rate
Journal of Microbiology Immunology and Infection, 2015Co-Authors: M C Chiang, F.-c. ShenAbstract:Purpose: Sterilization is an important indicator of quality infection control and patient safety it. Supply Center main business is to provide repetitive use of equipment and medical supplies sterilization services, equipment and medical supplies to be totally sterilized before reduce the chances of infection in patients; therefore repetitive use of the equipment, ensure the quality of its sterilization for patient safety and efficiency avoid crossinfection is very important. This case occurred in the execution unit Autoclave job is due to the human factor is not really start vacuum Autoclaves, not placed in a pressure cooker and biological indicator biological indicator Failing culture results, based on the implementation of the instrument of issuance; a series of omissions sterilization is not really caused by the effect of the unusual event. Failure Modes and Effects Analysis by the way in the implementation process to explore the hidden vacuum Autoclave sterilization potential risk of failure to ensure that the human operator Vacuum Autoclave process correctly. In order to avoid similar incidents from happening again, so the idea of using healthcare Failure Mode and Effects Analysis (HFMEA) of practices, excavations blind spots, improve work habits and processes, reduce the risk of sterilization failure, in order to enhance the supply of central vacuum sterilized in an Autoclave quality indeed effect correct rate of 100%. Methods: “Sterilization processes and performance failures” improvement measures: 1. sterilization abnormal review meeting 2. Organize in-service education - Vacuum Autoclave sterilization proper operation of the use and effectiveness of really strong cognitive effect, should be “biological indicators dish” culture results as the basis for issuance of instruments and shelves. 3. Develop a “high-pressure steam sterilizer operation flow chart” by flowchart view of attempts to prevent personnel can not start where the body of the pressure cooker link, thus requiring the officer shall chart recorder Autoclaves times, time, temperature, and signature body in a pressure cooker. 4. Amendment “Autoclave performance history table (packing area)” and the new “supply room Autoclave Effectiveness Monitoring Form (sterile material storage areas).” Record form to partition responsible manner and in accordance with the effectiveness of the sterilization record cooker correct food items placed PCD challenge pack. 5. View, after the collection of information and discussion with the infection control unit, modify ISO BNCB0C316 Autoclaves operating operating standards. 6. The implementation of all the equipment package tray, not subcontractors cloth or PE bag and send consumer items, are to be placed “within the Autoclave bag chemical indicator strip” As the use of units sterilization effect is indeed the last line of defense. Results: After the implementation of improvement measures, high risk factor dropped by 8 0, sterilized in an Autoclave quality vacuum effect is indeed correct rate of 100%. Conclusions: By improving HFMEA anticipatory risk management style and processes, which can effectively avoid the sterilization efficacy due to human error caused the failure. With unusual event, let the unit colleagues to re-examine the effectiveness of the sterilization acuity individuals really effective, although improvements have to re-learn the process to fill the form and change the past, wrong mode of operation; but in order to ensure effectiveness and maintain sterilization is an urgent need to change patient safety . The purpose of the measures applied in the same low-temperature plasma sterilizer and ethylene oxide sterilizer can achieve even this improvement.
