AIMS Our aim was to clarify the location and structure of the outlet septum relative to the free-standing subpulmonary infundibulum in the setting of tetralogy of Fallot and to examine its relationship to the other components of the subpulmonary outflow tract, determining their potential influence on clinical outcome. METHODS AND RESULTS We studied prospectively 41 patients with tetralogy of ...

This paper presents recent developments on a dynamic model for a mono-tube cavity receiver for direct steam generation with large scale parabolic dishes. Simulations of the model show that it is possible to assume a homogeneous distribution of heat flux along the receiver pipe without loosing accuracy in the calculation of receiver outlet temperature. The model in its current state produces an ...

PURPOSE We quantified the physiological variability of clinical and pressure-flow study variables in patients with symptomatic benign prostatic enlargement. MATERIALS AND METHODS Symptom scores were measured, and advanced urodynamic studies with pressure-flow analysis were performed in 178 patients before and 6 months after a period a watchful waiting. RESULTS Patients without bladder outle...

Axillosubclavian vein thrombosis, also referred to as effort thrombosis or Paget–Schroetter syndrome, is the most common presentation of the venous form of thoracic outlet syndrome. With timely diagnostic and therapeutic measures, thrombosis of the axillary or subclavian veins can be treated with minimal long-term morbidity. Case reports and single-center reviews have greatly contributed to our...

Discharge from marine-terminating outlet glaciers represents a key component of the Greenland Ice Sheet mass budget and observations suggest that mass loss from northwest Greenland has recently accelerated. Despite this, the factors controlling outlet glacier dynamics within this region have been comparatively poorly studied. Here we use remotely sensed data to investigate the influence of atmo...

The rotation speed of water at the inlet low hump outlet conduit has a great effect on its hydraulic performance. Therefore, influence different speeds loss and flow pattern is studied in this paper. By solving RANS equations RNG k-ε turbulence model, 3D field were calculated under speeds. To verify numerical results, model tests with guide vanes conducted. results show that along growth speed,...

[1] Measurements of sand flux and water flow in the Mississippi River are presented for a portion of the system 35–50 km upstream from the head of its subaerial delta. These data are used to provide insight into how nonuniform flow conditions, present in the lower reaches of large alluvial rivers, affect the timing and magnitude of sand transport near the river outlet. Field surveys during both...

introduction: cervical rib is relatively uncommon congenital abnormality that originates from the seventh cervical vertebrae and rarely from the sixth vertebrae. the purpose of this paper is to consider that this abnormal condition is an important cause of neurovascular compression at the thoracic outlet. methods: in this study all patients who were referred to radiology department of isfahan h...

"Thoracic outlet syndrome" is a term ascribed to a complex clinical entity encompassing complicated neurovascular signs, symptoms and pathology of the upper extremity. Controversies exist concerning its causes, diagnosis, and treatment despite years of intense study of hundreds of patients. Although there is no universal agreement on the diagnostic and treatment modalities to be applied to each...

sustained a whiplash injury in a car accident within the year, schedules an office visit for evaluation of pain she has been experiencing for 7 months in the right side of her neck and the trapezius. The pain radiates down the medial aspect of her right arm to the 4th and 5th digits, and it worsens when she brushes her hair or lifts bags of groceries. She feels her quality of life is significan...
