Purpose. For accurate resection of nonpalpable malignant breast lesions with a tumor-free resection rim, an exact and stable wire localization is essential. We tested the resistance towards traction force of different localization devices used in our clinic for breast lesions in two types of tissue. Materials and Methods. Eight different commercially available hook-wire devices were examined fo...

The aim of this paper is to conduct experimental modal analysis and numerical simulation to verify the structural characteristics of a deployable-retractable wing for aircraft and spacecraft. A modal impact test was conducted in order to determine the free vibration characteristics. Natural frequencies and vibration mode shapes were obtained via measurement in LMS Test. Lab. The frequency respo...

Approximately 132 agricultural tractor overturn fatalities occur per year. The use of rollover protective structures (ROPS), along with seat belts, is the best known method for preventing these fatalities. One impediment to ROPS use, however, is low clearance situations, such as orchards and animal confinement buildings. To address the need for ROPS that are easily adapted to low clearance situ...

OBJECTIVES To correlate topical steroidal treatment of stenosed foreskin with the different degrees of glans exposure and the length of time the ointment is applied. MATERIALS AND METHODS We studied 95 patients with phimosis, divided according to the degree of foreskin retraction. Group A presented no foreskin retraction, group B presented exposure of only the urethral meatus, group C present...

Background: Parkinson’s disease (PD) is most commonly modelled in rats via injection of the neurotoxin 6-hydroxydopamine (6-OHDA) into the medial forebrain bundle. Assessment of lateralised choice reaction time is usually conducted in the 9 hole box, a highly specialized apparatus that is not widely available in many behavioural laboratories. The retractable lever Skinner box on the other hand ...
