lhead of the tibia the horizontally shaded portion represents the extent to whiclh the upper and posterior portion of the head of the tibia is covered. The dotted line running from the top of the capsule from before backwards (throuah the vertically slhaded portion) shows the extent to wlicih the outer side of the shaft is overlapped. Fig. 3 is from a skiagram taken with the knee in semiflexion...

evaluation of activated charcoal sampler tubes

this study has been conducted to evaluate the effectiveness of the local made charcoal tubes against adsorption of benzene, toluene and xylene vapors. results indicate that desorption capacity and the recovery percentage decrease as the benzene, toluene and xylene concentrations and also relative humidity increase. it is concluded that the water vapor is the major interfere in the adsorption of...

production of activated charcoal sampler tubes for sampling air contaminants

the importance of the use of activated charcoal tubes for sampling gases and vapors is very well-known. for producing these tubes in the country, their production started in the laboratory of the department of occupation al health using activated charcoal, polyurethane foam and glass wool and consequently two types of foamed and foamless tubes were produced. to investigate the quality of the ra...

Guide Wire J-Tip Technique for Easy Exchange of In Situ Endotracheal Tubes

Novel wire-guided fine-gauge bougie dilator for transpapillary or endoscopic ultrasonography-guided biliary drainage.

Endoscopic management of biliary stricture generally requires dilation using devices such as an endoscopic retrograde cholangiopancreatography (ERCP) balloon dilation catheter before stenting [1]. Endoscopic ultrasonography (EUS)guided biliary drainage (EUS-BD) also requires fistula dilation before stenting. Recently, ultraslim balloon catheters [1] and diathermic dilators [2] have also been de...
