Prepping the knee in maximal flexion: getting into every nook, cranny, and fold

This article describes a simple surgical skin preparation technique for total knee arthroplasty that permits the application of skin prep agent with the knee in maximal flexion. While most surgeons prep the knee in extension, it is believed that prep of the knee in flexion will provide superior coverage of the skin surface and reduce the potential for surgical-site infection, particularly in ob...

When every $P$-flat ideal is flat

In this paper‎, ‎we study the class of rings in which every $P$-flat‎ ‎ideal is flat and which will be called $PFF$-rings‎. ‎In particular‎, ‎Von Neumann regular rings‎, ‎hereditary rings‎, ‎semi-hereditary ring‎, ‎PID and arithmetical rings are examples of $PFF$-rings‎. ‎In the context domain‎, ‎this notion coincide with‎ ‎Pr"{u}fer domain‎. ‎We provide necessary and sufficient conditions for‎...

Title Design of light element analysis system in BNCT and every NCT

Introduction: The Monte Carlo simulation is used to enhance reliability in the experiments related to nuclear instruments. in addition, that is used to calculate the different components of the neutron and gamma ray fluxes in boron neutron capture therapy(BNCT) and neutron capture (NCT)applications. BNCT is one of the methods in radiotherapy, that is used the neutron beam for ki...

Drug-eluting stents: effective and safe for every patient and every lesion?

When Andreas Grüntzig performed the first percutaneous transluminal coronary angioplasty in 1978, he did not expect that this procedure would become one of the most often performed interventions in medicine worldwide. The Achilles’ heels of balloon angioplasty were early reocclusions and restenosis. However, .60% of the patients after plain old balloon angioplasty did well without any need for ...
