The paper considers using of the simulator "tube-in-tube" and “shell-and-tubes” heat exchangers

The "Počitelj" tunnel was built as part of the section highway Mostar North - border with Republic Croatia on corridor Vc, Počitelj Bijača, subsection Zvirovići a length approx. 11.50 km. is two-tube, two-lane 1163 m right tube and 1192 left tube.

A cylindrical transmembrane molecule is constructed by linking hydrophobic sites selected from a coarse grain model. The resulting hollow tube assembly serves as a representation of a transmembrane channel, pore, or a carbon nanotube. The interactions of a coarse grain di-myristoyl-phosphatidyl-choline hydrated bilayer with both a purely hydrophobic tube and a tube with hydrophilic caps are stu...

Background: Normal Eustachian tube function is one of the important factor required for successful tympanoplasty outcome. A clinically useful test for assessment of Eustachian tube function is still lacking. Aims And Objectives: To evaluate Eustachian tube function by impedance audiometry and compare the outcome of surgery with respect to graft take up in normal and abnormal Eustachian tube fun...

PURPOSE To describe the use of a new, frosted Jones Pyrex tube in the treatment of obstructed canaliculi of the upper lacrimal system. The frosted Jones tube retains the advantages of the traditional smooth Pyrex tube yet appears to improve the positional stability in the surgically created fistula. METHODS Ten patients of a single surgeon who had previously undergone external conjunctivodacr...

PURPOSE OF REVIEW The purpose of this review is to summarize the recent knowledge on eustachian tube dysfunction and the patulous eustachian tube. RECENT FINDINGS A clinically useful test for eustachian tube function is still lacking. Narrowing of the isthmus alone was demonstrated to be an insufficient cause of otitis media. Inflammatory mediators identified within the eustachian tube and mi...

BACKGROUND Adhesive tape is commonly used to secure the endotracheal tube (ETT) in anesthesia and intensive-care settings. OBJECTIVE To determine the force required to extubate when the ETT is secured with adhesive tape or commercially available ETT holders. METHODS We orally intubated a simulation manikin with a standard 8.0-mm inner-diameter ETT, inflated the cuff to 20 cm H(2)O, and mea...
