1. Concurrent stone stabilization improves ultrasonic and pneumatic efficacy during cystolithopaxy: an in vitro analysis
Objective To identify whether stabilization of larger bladder stones would improve the efficacy of combination (ultrasonic/pneumatic) lithotripsy in a phantom bladder stone model for percutaneous cystolithopaxy. Materials and Methods Using 1cm phantom Bego stones, a spherical model bladder was used to simulate percutaneous bladder access. A UroNet (US Endos

3. DEVELOPMENT OF A THREE DEGREE-OF-FREEDOM PNEUMATIC LINK FOR FLEXIBLE ROBOTIC MANIPULATORS / DESENVOLVIMENTO DE UM ELO PNEUMÁTICO DE 3 GRAUS DE LIBERDADE PARA MANIPULADORES ROBÓTICOS FLEXÍVEIS
Recently, the concept of flexible manipulators has attract great interest. These devices present a continuously deforming vertebral column, in opposition to the traditional robotic manipulators link/joint/link with rigid links. Flexible systems offer a potential increase in the capacity of interaction with the environment, being apt to adjust itself to the c

4. Exposição ocupacional a poeiras em marmorarias: tamanhos de partículas caracteristicos
The main occupational hazards found in workplaces include dust exposure, facilitating the increase of respiratory diseases, of which silicosis is the most important. Due to the importance and gravity of the occupational exposure to dust and to the high number of workers exposed, the aim of this paper was to study the characteristics of this exposure in the o

7. Acute effects of vibration on peripheral blood flow in healthy subjects.
OBJECTIVES: The main objective was to study the acute vascular effects in the hands of normal healthy subjects of a complex vibration spectrum similar to that generated by many industrial hand held tools. The effects of repeated bouts of vibrations and alterations in the intensity of vibration were also studied. METHODS: Blood flow was measured by venous occ

8. A cross sectional epidemiological survey of shipyard workers exposed to hand-arm vibration.
The hand-arm vibration syndrome, widely known as vibration white finger, is a disorder of nerves and blood vessels that occurs in workers exposed to segmental vibration. A cross sectional symptom survey was performed on a sample of workers employed by a large shipyard in the north eastern United States. Random samples were drawn from departments composed of

9. Detailed clinical assessment of neurological function in symptomatic shipyard workers.
Forty eight patients with extensive occupational exposure to pneumatic grinding tools were evaluated at a university sponsored occupational health clinic. All patients were interviewed and examined by a physician and assessed neurologically with standard clinical, functional motor, quantitative vibrotactile, and electrodiagnostic tests. Sensorineural symptom
