The Advanced Photon Source (APS) currently under construction at Argonne National Laboratory will be one of the world’s brightest synchrotron radiation facilities. The storage ring, capable of storing currents up to 300 mA at 7.0 GeV and 200 mA at 7.5 GeV, will produce very intense and energetic synchrotron radiation (Ec = 24 keV for bending magnets and Ec = 37.4 keV for wigglers, where Ec is t...

Colloidal Gas Aphron as a mobility control in enhanced oil recovery is becoming attractive; it is also designed to block porous media with micro-bubbles. In this paper, the effects of surfactant concentration, polymer concentration, temperature and salinity on the bubble size of the Colloidal Gas Aphron were studied. Effects of injection rates, Colloidal Gas Aphron fluid composition, heterogene...

Introduction: Ultra-high molecular weight polyethylene (UHMWPE) is the most widely used bearing surface option in total hip arthroplasty. Radiation cross-linking has improved the wear resistance of conventional UHMWPE. Radiation cross-linking also generates residual free radicals, adversely affecting long-term oxidative stability. Post irradiation melting is effectively used to eliminate residu...

Nineteen patients on whom pneumonectomy was performed because of bronchial cancer were investigated preoperatively with spirometry and '"{Xe-radiospirometry. Postoperative lung function was predicted from these examinations. One month to one year postoperation the patients were reinvestigated with spirometry and arterial blood gas analyses and the obtained values were compared with the preopera...
