The use of ultraclean air (UCA) in operating theatres reduces the infection rate after joint replacement but some cases of infection still occur. We investigated one possible source of contamination, namely the setting up of instruments in a conventional plenum-ventilated preparation room. We measured bacterial fallout using agar settle plates and compared instruments set up in the preparation ...

AIM To assess the reproducibility of clinical diagnosis of occlusal caries using unaided visual examination and examination with an operating microscope (16 x magnification) and to determine the agreement between these 2 methods. MATERIALS AND METHODS Three experienced dentists used unaided visual examination and an operating microscope to grade, according to a standard caries rating scale, a...

this study aims at presenting a numerical model for predicting grout flow and penetration length into the jointed rock mass using universal distinct element code (udec). the numerical model is validated using practical data and analytical method for grouting process. input data for the modeling, including geomechanical parameters along with grout properties, were obtained from a case study. the...

In this paper, there is an attempt to construct the notion of interstijectivity as a process of a coorakztion of participants’ contributions in joint activity. This notion incorporates the dynamics of bothagreement anddisagreement. Iargue thata traditionaldejbitionof intersubjectivityasastate of overlap of individual unakstandings overemphasizes agreement and&-emphasizes disagreement among the ...

BACKGROUND Treatment of acute complete acromioclavicular (AC) dislocation is still controversial. Both non-surgical and surgical methods have been reported with similar results. In addition, once surgical treatment is chosen, a satisfactory surgical technique has not been developed yet. METHODS Sixty consecutive patients who sustained 60 acute complete AC dislocations were treated using corac...

background: personal protection equipments (ppes) should be easily accessible to decrease contact with infecting factors and also should be used purposefully to effectively keep the health care personnel in a safe distance from the patient blood and body fluid which can easily infect the operating rooms personnel. this study aimed to find the operating rooms' personnel compliance with standards...
