Context. The mysterious solar system object 133P/(7968) Elst-Pizarro is dynamically asteroidal, yet displays recurrent comet-like dust emission. Two scenarios were hypothesized to explain this unusual behavior: (1) 133P is a classical comet from the outer solar system that has evolved onto a main-belt orbit, or (2) 133P is a dynamically ordinary main-belt asteroid on which subsurface ice has re...

with the introduction of the use of seatbelts in cars, mortality following motor vehicle crashes has decreased significantly. however, two patterns of injuries, the ‘seatbelt sign’ and ‘seatbelt syndrome’ have emerged. injuries may consist of traumatic abdominal wall disruption. we present two cases of severe abdominal wall disruption caused by a seatbelt injury and treated with primary repair....

We discuss the structure of the Kuiper belt as it can be inferred from the first decade of observations. In particular, we focus on its most intriguing properties – the mass deficit, inclination distribution, the apparent existence of an outer edge and of a correlation among inclinations, colours and sizes – which clearly show that the belt has lost its pristine structure of a dynamically cold ...

We describe calculations of the evolution of an ensemble of small planetesimals in the outer solar system. In a solar nebula with a mass of several times the Minimum Mass Solar Nebula, objects with radii of 100–1000 km can form on timescales of 10–100 Myr. Model luminosity functions derived from these calculations agree with current observations of bodies beyond the orbit of Neptune (Kuiper Bel...

We present visible and near-infrared reflectance spectra and interpreted surface mineralogy for asteroid 10537 (1991 RY16). The spectrum of this object is without precedent amongst the Main Belt asteroids. A unique absorption band centered at 0.63 microns could be attributed to one of several mineralogies. Pronounced 1and 2-micron absorption bands suggest that the composition of 10537

The US Corn Belt supports agroecosystems that flourish in a temperate climate regime that could see significant changes in the next few decades. Because Wisconsin is situated on the northern, cooler fringes of this region, it may be the beneficiary of a warmer climate that could help support higher corn and soybean yields. Here we show that trends in precipitation and temperature during the gro...

President Nixon’s enactment of the 90-day “wage and price freeze” in 1971 appears to have met with mixed reaction from business circles. This would not seem surprising in view of the fact that the President’s announcement climaxed a year of relatively ineffective inflationary curbs, declining corporate profits, and business uncertainties of massive proportions. Throughout most of 1970 and the i...

In regard to the tectonic history of the Lachlan Fold Belt, Aitchison and Buckman (2012) argued that "numerous aspects of the observed geology appear to be incompatible with the existing model" and that an "alternative model envisages arc-continent collision events (quantum tectonics) as a primary means of largescale continental growth". My purpose is to challenge these arguments and to questio...

In this paper we present an initial study into the feasibility of using a mobile phone as a personal tactile display when interacting with a tabletop computer. There has been an increase in recent years in large touchscreen computers that use soft keyboards for text input. Text entry performance on such keyboards can be poor due to the lack of tactile feedback from the keys. Our approach is to ...

Clinical environments are complex, stressful, and safety critical-heightening the demand for technological solutions that will help clinicians manage health information efficiently and safely. The industry has responded by creating numerous, increasingly compact and powerful health IT devices that fit in a pocket, hook to a belt, attach to eyeglasses, or wheel around on a cart. Untethering a pr...
