27. Indoor chimate: Temperature Rise

Researchers ponder a 4°C temperature rise

In September 2009, scientists concerned over the lack of information available on the high-end scenarios of global warming held a conference at Oxford to pool their insights into the challenges the world will face if global temperatures rise by 4°C or more. Building on the information collected there, organiser Mark New and colleagues have now compiled a themed issue of the Philosophical Transa...

Evaluation of Temperature Rise and Thermal Lesion Dimensions in Liver Laser Interstitial Thermotherapy

Introduction:  Laser  interstitial  thermotherapy  (LITT)  is  an  internal  ablation  therapy  method  consisting of a percutaneous or intraoperative insertion of laser fibers directly into the liver tumor with  maximum diameter of 5 cm. In this treatment method, there isn’t any general information about the  relationship  between  increasing  the  exposure  power,  coagulation  and  carboniza...

Temperature Rise Comparison of Switchgear in SF6, N2, and Air

Based on the heat conduction equation, fluid flow governing equation and radiation heat transfer equation, a multi-physics coupled mathematical model is established, the convection heat transfer problem between solid and fluid is solved by wall function. The three dimensional thermal field in a type of switchgear filled respectively with SF6, N2, and air are calculated and analyzed to discuss t...

Temperature rise during photo-polymerization under ceramic restorations.

AIM The aim of this study was to measure the temperature increase induced by various light-curing units during photo-polymerization beneath ceramic restorations. METHODS Three light-curing units were used; a high intensity QTH unit Elipar 2500 and two LED units: Translux Power Blue and Excelled 1400. The 15 ceramic specimens (CEREC Blocks) used in this study were of 2.5 mm thickness, 5 mm wid...
