The Relationship Between Preoperative Fear and Postoperative Comfort in Otolaryngology Patients.

Purpose: This study was conducted to determine the relationship between preoperative fear and postoperative comfort in otolaryngology patients.

Design: This is a descriptive study.

Methods: The sample consisted of 282 patients undergoing otolaryngology surgery.

Investigation of OH bond energy for chemically treated alfa fibers.

This work aims to study the hydrogen bond energy and distance for different samples of alfa fibers treated with thymol. The treatment duration and thymol concentration were varied and seem to have a great influence on infrared band intensities and positions. The number of hydrogen bonds is related to the infrared band intensity, whereas their energy and distance depend on the infrared band position.

In-depth study of agave fiber structure using Fourier transform infrared spectroscopy.

FTIR spectroscopy is a powerful method to analyse materials and especially fiber structure. This technique is largely used to obtain quick information on the fiber composition and to detect possible transformations after physical and chemical treatments. Unlike other techniques, FTIR is a quick method which demands a reduced amount of fibers.

Physical and mechanical properties of Tunisian women hair.

Background: Mechanical analysis of human hair may provide the dermatologists with several markers of considerable diagnostic importance. The aim of this study was to analyse the physical and mechanical properties of Tunisian women's hair.

Methods: Surface characteristics were determined with scanning electron microscopy (SEM).

Ultrasonic preparation of cationic cotton and its application in ultrasonic natural dyeing.

Cationization of cotton fabric was conferred by the sonicator reaction of cellulose with bromoacetyl bromide, followed by substitution of the terminal bromo groups by triethylamine. Experiments showed that the optimal volume of bromoacetyl bromide necessary to succeed the first stage was 0.4 mL.
