Antimatter was first predicted 1 in 1931, by Dirac. Work with high-energy antiparticles is now
commonplace, and anti-electrons are used regularly in the medical technique of positron …

Introduction ORTHOPOD: Day Case Trauma is a multicentre prospective service evaluation
of day-case trauma surgery across four countries. It is an epidemiological assessment of …

We report the application of evaporative cooling to clouds of trapped antiprotons, resulting
in plasmas with measured temperature as low as 9 K. We have modeled the evaporation …

Production of antihydrogen atoms by mixing antiprotons with a cold, confined, positron
plasma depends critically on parameters such as the plasma density and temperature. We …

Background: Elongating intramedullary rods have been used in the management of osteogenesis
imperfecta for the past fifty years. The complication rates reported in many reviews of …

We have developed a new method, based on the ballistic transfer of preaccumulated
plasmas, to obtain large and dense positron plasmas in a cryogenic environment. The method …

The ATHENA apparatus that recently produced and detected the first cold antihydrogen
atoms is described. Its main features, which are described herein, are: an external positron …

We demonstrate controllable excitation of the center-of-mass longitudinal motion of a thermal
antiproton plasma using a swept-frequency autoresonant drive. When the plasma is cold, …

We have demonstrated storage of plasmas of the charged constituents of the antihydrogen
atom, antiprotons and positrons, in a Penning trap surrounded by a minimum-B magnetic trap …

Introduction Current practice following injury within the United Kingdom is to receive surgery,
at the institution of first contact regardless of ability to provide timely intervention and …
