Effective mole control is often difficult to achieve. Various types of traps, baits, and fumigants have been developed over the years to reduce mole damage to lawns, golf courses, and other areas. Two studies were conducted in the St. Louis, Missouri area to field test products currently registered by the EPA for mole control. Reliable census methods are required to determine efficacy. The best...
Meso/microforming has gained much more attention in the last decades and is widely used as a reliable method to fabricate meso/micro-scaled metallic components. In this research, compound meso/microforming system which combines deep drawing, punching, blanking operations was developed multiscale central-punched cups by using brass sheets. The parts with three scales were produced sheets various...
Reinforced concrete one-way slabs under concentrated loads can develop different shear failure mechanisms: as wide beams in shear, punching around the load or a mixed mode between them. Until now, most publications presented recommendations to assess capacity considering only mechanism. This study proposed developing both and of such slabs. Different codes practice were addressed, including cur...
INTRODUCTION Punching glass can cause severe and debilitating injuries. The literature is scant in regards to the injury patterns, optimal management, and preventative strategies. We have reviewed our experience of these injuries at a regional Australian hospital. METHODS A retrospective chart review of all patients who had punched glass and presented to Cairns Base Hospital between January 2...
Previous research has shown how dynamical systems theory provides a relevant framework for investigating decision-making behavior in sport. The aim of this study was to adopt concepts and tools from nonlinear dynamics in examining effects of boxer-target distance and perceived punching efficiency on emergent decision-making during a typical practice task in boxing. Results revealed the existenc...
DESCRIPTION A 39-year-old mechanic presented with a 6-week history of activity-related ulnar sided wrist pain in his dominant right hand after punching injury. History, physical examination, and imaging were consistent with a hamate body fracture nonunion. The patient underwent open reduction internal fixation and went on to bony union and restoration of function.
Filter paper discs saturated with dried blood can be used in the Immunotube solid-phase thyroxine radioimmunoassay. This assay utilizes polypropylene tubes to which antibody to thyroxine is covalently bound. The filter paper standards and samples are placed in the tubes, followed by an assay buffer that contains I125-labeled thyroxine and compounds to displace thyroxine from its binding protein...
We describe a technique for femtosecond laser-assisted preparation of donor tissue for Boston type 1 keratoprosthesis to provide accurate double punching of the donor tissue for optimized alignment in the visual axis. The technique was reproducibly performed in four donor corneas mounted in an artificial anterior chamber. This technique can provide optically centered donor tissue with smooth tr...
