INTRODUCTION The air contamination levels during orthopedic surgeries were evaluated. METHODS The air of operating rooms (ORs) was examined through exposure to microbiological plates placed near the surgical table for an hour. RESULTS values above that recommended (369 CFU/m³) for conventional ORs and ORs with ultraclean air were determined. Contamination was predominantly by Staphylococcus...

in this paper, a modeling tool for risk assessment analysis of the movement of hydrocarbon contaminants in the vadose zone and mass flux of contamination release into the groundwater table was developed. also, advection-diffusion-reaction equations in combination with a three-phase equilibrium state between trapped air, soil humidity, and solid particles of unsaturated soil matrix were numerica...

In this project, the quad processing machine for cutting, shaping, grinding and drilling machines is kept to be in same attachment. This eliminates risk of material handling table. unit driven by 0.25 H.P. three phase motor 1440 rpm. linked with cast-iron (CI) slider. enables slide get rotation movement into reciprocating motion having a stroke length 75mm. The head slotting can tilted getting ...

Table olives are the most important fermented vegetables because of their worldwide economic importance. The three main techniques for table olive production used in Italy concern 82% green olives, 16% black olives and 2% processed at the cherry ripened stage (UNAPROL, 2008). There are three main trade preparations of table olives: Spanish-style olives, Californian-style olives and naturally bl...

This paper describes the investigation for the feasibility of inspection of steel-rocasin rubber specimen used in rocket motor for detection of debond by using air-coupled ultrasonic. A pair of high performance air-coupled transducers was used to generate and receive the high intensity ultrasonic pulses. Probes were placed at the opposite side of the specimen during inspection. It was shown tha...

Slide fasteners are one of the textile end-uses that have permeated daily life. The objective is to elucidate ways improve quality and value slide fasteners. In this report, from viewpoint tactile perception on tensile load transmitted user’s fingers through a slider in sliding fastener, sensory affective impressions (hereinafter referred as slide-feeling) quantitative evaluation indexes slide-...

During our study of the relationship between propagule size and reproduction capacity of microorganisms on agar media1), it was necessary to determine concentrations of various species of bacteria and actinomycetes. Since bacterial counts made in haemacytometer had been shown to be unreliable because the amount of samples counted was not precise3,4,5) and difficult due to insufficient color con...
