starch is a versatile and useful polymer having physicochemical properties that can be altered by chemicals or enzymatic modification and/or physical treatment. native starches possess many disadvantages that decrease their application and industrial use, but could be modified to obtain the desired properties to meet industrial needs for a wide range of starch applications. physically modified ...

PURPOSES To assess osteoporosis using plain radiography of the calcaneum by studying the performance characteristics of the modified calcaneal index through inter- and intra-observer agreement. To study the correlation of the modified calcaneal index to quantitative ultrasound of the calcaneus and bone mineral density (BMD) of the femoral neck and distal radius. METHODS Lateral calcaneal radi...

AIM To establish a modified B-ultrasound method of measuring the antral section only to assess gastric motility in healthy people, and evaluate its application in guiding enteral nutrition (EN) in critically ill patients. METHODS First, 30 healthy volunteers were selected. The modified B-ultrasound method and the traditional B-ultrasound method were applied to assess gastric function. The cor...

A robot system for positioning an ultrasound probe has been developed [1]. Ultrasound visual servoing can be used to help ultrasound technicians position the ultrasound probe. The feasibility of visual servoing for motion in the plane of the ultrasound probe in one dimension has been addressed here. Tracking of the carotid artery for a long period of time has been demonstrated in real-time. Two...

BACKGROUND AND AIMS Endotracheal tube (ETT) selection in pediatric patients is mainly done with the age, height, or weight-based formula. We compared ultrasound assessment of the subglottic area to predict the outer diameter of the ETT, with that of modified Cole's formula. The aim of the study is to compare the appropriateness of uncuffed ETT selection based on modified Cole's formula with tha...

ABSTRACT: In this study, response surface methodology was used to optimize ultrasound osmotic pretreatment with finished freeze drying of black cherries. Freeze drying is a separation process based on the  sublimation phenomenon. This process has the following advantages as compared to the conventional drying process, maintenance of the structure, moisture removal at low temperature (reduced tr...

In a recent article by Lausten, J#{248}rgensen and Boesen (1989) anteversion (AV) of the femoral neck was measured directly, by ultrasound, and by computerised tomography (CT). The authors reported poor correlation between the angles measured by ultrasound and the two other methods, and concluded that ultrasound at present seemed unsuitable for the measurement of femoral anteversion. We believe...

abstract: in this study, an analytical method is developed to determine 15 polycyclic aromatic hydrocarbons (pahs) in olive and refined pomace olive oils using hplc coupled with a fluorescence detector. the standardised method of ultrasound-assisted solvent extraction consisted of liquid–liquid extraction with organic solvent and purification on c18 and florisil bonded-phase cartridges was modi...
