The circumference of the knees and thighs at three locations was measured in 10 patients on two consecutive occasions by three observers. Analysis of the results for interobserver, intraobserver and among-patient variation established that a change in circumference noted by different observers on two different days is significant if it exceeds 1-5 cm at the midpatella, 2-7 cm at 7 cm above, and...

This paper is concerned with a new type of deployable structures that can be rolled up like a tape measure but, unlike a tape measure, are stable in two different configurations. The key to the behaviour of these structures is a particular type of composite construction based on an anti-symmetric lay-up of glass fibres in a polypropylene matrix. The paper presents a finite element analysis usin...

Public administration research is actively exploring alternatives for the General Red Tape (GRT) scale to measure red tape. Owing increasing criticism on GRT scale, scholars proposed Three-Item (TIRT) as an alternative. Using a repeated cross-sectional design, this article tests both scales in before–after analysis of major change organization hospital. The results indicate that does not captur...

Objective: The Objective of this study was to determine the intrarater reliability of chest expansion at three different anatomical landmarks using a cloth tape measure among healthy peoples. Materials and Methods: 120 healthy male and female volunteers were evaluated on two occasions in different days. The measures consisted of chest expansion measurement at axilla, fourth intercostals and xip...

OBJECTIVE To assess the reliability of using a cloth tape measure to determine thoracic respiratory excursion as a measurement of chest expansion or mobility. METHODS Physicians and residents experienced in osteopathic manipulative treatment measured thoracic excursion with a cloth tape measure held around the circumference of healthy male subjects' chests at two levels. Upper thoracic excurs...

OBJECTIVE To determine the efficacy of various eye protection measures during carbon dioxide laser laryngoscopy. DESIGN A standard medical mannequin was equipped with indicator paper over the eyes and subjected to multiple passes of direct carbon dioxide laser beam contact at 400-mm focal length with powers ranging from 2.5 to 4.0 W during simulated laser microlaryngoscopy. Several different ...

The purpose of this paper is to present a clinically feasible method to provide objective, quantitative information regarding the quality of a patient's gait. The technique used is simple and economical and requires minimal equipment. The four basic temporal and distance factors are 1) stride length, 2) step length, 3) cadence, and 4) velocity. The technique requires the following equipment: 1)...

A simple, non-invasive dermal sampling technique was developed and tested on 22 human volunteers under laboratory conditions to estimate acute dermal exposure to jet fuel (JP-8). Two sites on the ventral surface of each forearm were exposed to 25 micro l of JP-8 and the non-viable epidermis (stratum corneum) was sequentially tape-stripped using an adhesive tape. Samples were extracted with acet...

BACKGROUND Protective ventilation implementation requires the calculation of predicted body weight (PBW), determined by a formula based on gender and height. Consequently, height inaccuracy may be a limiting factor to correctly set tidal volumes. The objective of this study was to evaluate the accuracy of different methods in measuring heights in mechanically ventilated patients. METHODS Befo...
