A steam sterilizer (autoclave) was tested to determine the operating parameters that affected sterilization of microbiological waste. Tests involved standardized loads (5, 10 ad 15 lb [ca. 2.27, 4.54, and 6.80 kg, respectively]) contaminated petri plates in autoclave bags placed in polypropylene or stainless steel containers. Thermal and biological data were obtained by using a digital potentio...

Out-of-autoclave prepreg typically needs a long cure cycle to guarantee good properties as the result of low processing pressure applied. It is essential to reduce the manufacturing time, achieve real cost reduction, and take full advantage of out-of-autoclave process. The focus of this paper is to reduce the cure cycle time and production cost while maintaining high laminate quality. A rapidly...

To evaluate the dimensional changes after disinfection of elastomeric impression materials with Ozone water, sodium hypochlorite, and autoclave method. A total 40 impressions were made divided into 4 groups according to type sterilization method used (Group 1: Control without use disinfectant, Group 2: Autoclave, 3: 4: ozone water method) 10 in each group. Impression group contaminated Pseudomo...

introduction microorganisms have an essential role in pulpo-periapical pathosis, therefore obtaining a successful treatment has a direct relationship with their elimination. according to previous studies, the most reliable method of sterilization is autoclave ,but in some instances there are limitations for using this method, and we need an alternative .one of the most popular and wide-spread m...

Five brands of ethylene oxide- and autoclave-sterilized membrane filters were examined for their ability to recover fungi from natural waters. Results showed that the recovery on Gelman membranes was consistently higher than on the other brands tested.

Out-of-autoclave (OOA) manufacturing techniques for composites result in lower fibre volume fractions than fully compressed laminates. The fraction produces a higher resin fraction, which becomes resin-rich volumes (RRV). Textile reinforcements with clustered fibres and consequent RRV generally have low strength but high in-plane process permeability, whereas the opposite is true uniformly dist...

The effect of ultrasound on the pseudo-solubility of nitrogen in water and on gas-liquid mass transfer kinetics has been investigated in an autoclave reactor equipped with a gas induced impeller. In order to use organic liquids and to investigate the effect of pressure, gas-liquid mass transfer coefficient was calculated from the evolution of autoclave pressure during gas absorption to avoid an...
