EXPERIMENTAL APPROACHES TrachéalTube Cuffs and TrachéalDilatation"
نویسندگان
چکیده
Although trachea! tube cuffs are well known to injure the trachea, attempts to design safer cuff systems have been only partially successful. In 14 dogs, we compared three models of high residual volume, low pressure cuffs, which are considered to be among the safest. Two were air-filled cuffs —a maintained pressure cuff and a balloon reser voir cuff —and the third was foam-filled. Trachea! dila tation was considerably more severe with mechanical ven tilation than with spontaneous breathing, but the foam cuff produced significantly less dilatation (P < .005) than the air-filled cuffs.

Shrinkage Curve: Experimental Study and Modelling
In order to study the shrinkage process of clayey soil, we perform a modified laboratory test allowing to measure simultaneously and continuously the vertical displacement and the weight of natural state specimen. The experiment was conducted on undisturbed clayey specimen. Using the experimental results, and on the basis of the existing relation between the soil water content and its structura...

متن کاملModular approach for an ASIC integration of electrical drive controls
VLSI circuits design allows today to consider new modes of implementation for electrical controls. However, design techniques require an adaptation effort that few designers, too accustomed to the software approach, provide. The authors of this article propose to develop a methodology to guide the electrical designers towards optimal performances of control algorithms implementation. Thus, they...
متن کاملThermal Analysis of Laser Hardening for Different Moving Patterns
Transient thermal field in laser surface hardening treatment of medium carbon steel was analyzed by employing both three-dimensional analytical model and finite element model. In finite element model the laser beam was considered as a moving plane heat flux to establish the temperature rise distribution in the work-piece, while in analytical model laser beam was considered as an internal heat s...
متن کاملSettlements and Consolidation Rates under Embankments in a Soft Soil with Vertical Drains
In this paper, a study was carried out in order to estimate settlements and consolidation rates under embankments constructed on Moroccan soft soils. Settlement measurements in several embankments in High Speed Railway project between two Moroccan cities, Tangier and Assilah, were analyzed. The objective of this study is to estimate settlement values and settlement rates, with sufficient prec...
