Thermal Analysis of Tire
One of the great enemies of rubber compounds is heat. Heat will cause chemical and physical degradation of vulcanized rubber as well as a considerable loss in its strength. A major source of heat generation in a tire is due to internal friction resulting from the viscoelastic deformation of the tire as it rolls along the road. Another source of heat generation in a tire is due to its contact fr...

متن کاملAnalysis Of Elastomer Refrigeration Cycles
Refrigeration effects can be obtained from elastomers classified as “ideal rubber” by operating over a cycle similar to that of the Carnot cycle. The interesting properties of ideal rubber have long been recognized, with most investigations of potential thermodynamic cycles devoted to power cycles. This paper focuses on the development of refrigeration cycles constructed from ideal rubber refri...
متن کاملComparison of infrared coagulation and rubber band ligation for first and second degree haemorrhoids: a randomised prospective clinical trial.
One hundred and thirty seven previously untreated out-patients with first and second degree haemorrhoids were allocated at random to treatment by infrared coagulation (n=66) or rubber band ligation (n=71). Complete follow up was obtained in 122 patients (60 who had undergone infrared coagulation (group 1), and 62 rubber band ligation (group 2)) at periods from three months to one year after com...
متن کاملComparison of hemorrhoidal treatment modalities. A meta-analysis.
PURPOSE The purpose of this study was to assess whether any method of hemorrhoid therapy has been shown to be superior in randomized, controlled trials. METHOD A meta-analysis was performed of all randomized, controlled trials assessing two or more treatment modalities for symptomatic hemorrhoids. Outcome variables included response to therapy, need for further therapy, complications, and pai...
