A study of the behaviour of pressurized piping elbows
The behaviour of piping elbows under bending and internal pressure is more complicated than expected. The main problem is that the coupling of bending and internal pressure is non-linear; stress and displacement cannot be added according to the principle of superposition. In addition, internal …

The Effect of CT Display Window and Image Plane on Diagnostic Certainty for Characteristics of Canine Elbow Dysplasia
… with canine elbow dysplasia. Fifty dysplastic elbows and ten clinically normal elbows were selected for imaging. Computed tomographic image data from selected elbows were filmed in transverse, sagittal and dorsal planes, with each plane filmed in window widths of 1500, 2500, and 3500 HU. Two …

Musculoskeletal disorders in demanding computer work - with air traffic control as a model
… work environment by questionnaire. Disorders in elbows/hands increased significantly after 20 months of work in the mouse-intensive system, while in neck/shoulders/upper back, there was no consistent change. There was no gender difference in elbows/hands disorders, while the females were at …

Reconstruction of industrial piping installations from laser point clouds using profiling techniques
… elements e.g. straight pipes, t-junctions, elbows, spheres. The automatic detection of these piping elements in point clouds has the greatest impact on the reconstructed model. Various algorithms have been proposed for detecting piping elements in point clouds. However, most algorithms …

CFD modelling of pipe erosion under multiphase flow regimes.
… the simulation resources to predict erosion in elbows mounted in series. Results from both modelling techniques were compared. Results show that phase distribution plays a vital role in estimating erosion in complex multiphase flows. The presence of a separation distance results in a change in …

Numerical and experimental methods for seismic risk assessment of civil and industrial structures
… as “special risk” plants. Although tanks, pipes, elbows and bolted flanges have been a major concern in terms of seismic design, generally, they have not been analysed with modern performance-based procedures. This thesis will explore some important themes in seismic risk assessment with a special …

Pulse Propagation in Fluid-Filled Elastic Curved Tubes
The propagation of fluid transients through elbows in pipes is an important consideration in the safety analysis of nuclear piping systems. In this study, one-dimensional governing equations for the propagation of pressure pulses in an inviscid compressible fluid contained in a thin-walled …

Development and validation of a computational multibody model of the elbow joint
… tomography (CT) scans obtained from cadaver elbows. The ligaments and triceps tendon were modeled as spring-damper elements with non-linear stiffness. Articular cartilage was represented as uniform thickness solids covering the articulating bone surfaces. Finally, the model was validated by …

The determination of the operating characteristics of an 18- inch stoneware gas absorption tower
… spiral cooling unit made from 5-inch stove pipe elbows. The elbows were coated with silicone resin in an effort to reduce corrosion. The capacity of this unit was approximately 50% greater than the open-spray type sealer used previously. The examinator used heretofore to measure gas velocities …

Preliminary investigation of the use of electromyographic signal for the control of a prosthetic ankle
… state machine control and active prosthetic elbows under electromyographic (EMG) based control. In this paper, an investigation of methods for collecting EMG and ankle angle data are reviewed and a preliminary correlation of the two is developed. Experimental hardware has been designed to …

A Comparison of Brain Trauma Characteristics from Head Impacts for Lightweight and Heavyweight Fighters in Professional Mixed Martial Arts
… Next, head impacts (punches, kicks, knees and elbows) from fight videos were visually estimated to determine their corresponding magnitude range and establish the frequency distribution of impact magnitudes. The study revealed no significant differences in overall impact frequency and interval …

Subtrochlear sclerosis evaluation for medial coronoid disease detection and dynamic distal ulnar ostectomy for reduction of disease progression in Labrador retriever puppies
… involvement score. DDUO was performed on all elbows with >20% joint involvement. At 12-months-old, all dogs underwent elbow computed tomography to determine the development of MCD. Results The only method predictive of disease development was SVR’s subjective evaluation of STS, with a …

Hand hygiene compliance in the intensive care unit of the Onderstepoort Veterinary Hospital, South Africa
… the majority of them were not bare “below the elbows” because they wore jewellery. The overall hand hygiene compliance was 24.3% (178/734). The most common method of hand hygiene was hand rub (58.4%) followed by hand-wash (41.6%). Nurses had a higher (44%) level of compliance compared to …

Lamin A and lamin C are differentially dysfunctional in autosomal dominant Emery-Dreifuss muscular dystrophy
… characterised by early contractures of the elbows, Achilles tendons and spine, slowly progressive muscle wasting and cardiomyopathy associated with cardiac conduction defect. The autosomal dominant form is caused by mutations in the LMNA gene which gives rise to lamin A and lamin C proteins …

The history of Tuolumne County during the gold rush
… Chinese, Negroes, Irishmen, and Chileans rubbed elbows and occasionally fists with each other. The region was full of gamblers, drunkards, fast women and lumps of gold.</p><p>Before the great rush for gold, California was a quiet, peaceful, sparsely settled land. In 1842, the population was about …
