Transient quadriplegia is a rare injury that can change the course of an athlete's career if misdiagnosed or managed inappropriately. The clinician should be well versed in the return-to-play criteria for this type of injury. Unfortunately, when an unknown preexisting syrinx is present in the athlete, there is less guidance on their ability to return to play. This case report and review of the ...

This paper analyzes job mismatches in Switzerland based on a subjective measure of overqualification. According to job search and job matching theories, overqualification is a transitory problem for the individual worker that results from informational deficits. This problem ceases to exist once access to better information about the labor market allows the worker to move to a job with a better...

article looks at definitions of peace from a cultural studies perspective, suggesting that binary oppositions governing such fields as peace and war, individual and society, tradition and modernity offer few grounds for progress towards peace. The article suggests instead that the utopian principle of hope can be recruited for a culture of peace based on the surrender to difference, at a subjec...

In several recent articles, we have investigated in some detail one-dimensional electrostatic potentials by means of both the Schrödinger [1–3] and the Dirac equation [4–6]. Several original phenomena have been observed, such as the transition from resonance phenomena to multiple (infinite) peak formation [5] equivalent to a shift from wave-like to particle behavior in the barrier diffusion zon...

Tob Control Published Online First: [please include Day Month Year] doi:10.1136/ tobaccocontrol-2013051079 As the old adage attributed to Benjamin Franklin puts it, there are only two things in life that are certain: death and taxes. In the case of cigarette smoking, they are closely related. Raising cigarette prices, primarily by increasing cigarette taxes, reduces smoking,...

There has been debate in the literature concerning whether the clavicle arises by intramembranous ossification, i.e. is a membrane bone, and whether secondary cartilage develops from its periosteal cells. A histological study of carefully staged embryos revealed that pre-clavicular mesenchyme undergoes condensation at H.H. stage 31-32, bone forms by H.H. stage 33 and that a transitory secondary...

hydrogen is an unusual substance in that its molecule exists in two forms, known as ortho and para, with markedly different properties. energy level of the ortho molecule is higher than para, therefore, the latter is employed for industrial purposes. consequently, for a high  conversion of  ortho to para hydrogen a catalyst reactor must be employed.  therefore, one of  the main objectives of th...
