Pre-heating mitigates composite degradation [PDF]
Dental composites cured at high temperatures show improved properties and higher degrees of conversion; however, there is no information available about the effect of pre-heating on material degradation.

Composite Pre-heating: A Novel Approach in Restorative Dentistry. [PDF]
Resin composite pre-heating is a novel approach that might improve handling and marginal adaptation of the unset material paste in clinical application. The goal of this review article is to compile all laboratory experiments on resin composite preheating and see how it impacts the mechanical properties of the material.

Effect of Pre-Heating Prior to Low Temperature 0.1 µm-Microfiltration of Milk on Casein–Whey Protein Fractionation [PDF]
During skim milk microfiltration (nominal pore size of 0.1 µm) at 10 °C, the whey protein purity in the permeate is reduced by an enhanced serum casein permeation, primarily of β-casein.

Influence of Oxy-Fuel Lance Parameters on the Scrap Pre-Heating Temperature in the Hot Metal Ladle
As one of the vital ways to improve the converter heat balance and increase the scrap ratio, scrap pre-heating technology has attracted much attention from researchers. The aim of this paper is to reveal the effect of the oxy-fuel lance parameters on the

Pre-heating in the framework of massive gravity
In this paper we propose a mechanism of natural pre-heating of our universe by introducing an inflaton field dependent mass term for the gravitational wave for a specific class of massive gravity theory.

Effect of increased venous blood flow with acute passive heating on volume and compliance in the calf vein in young adults [PDF]
Arterial endothelial function—impairment of which is a risk factor for cardiovascular disease—increases after acute passive heating; however, whether venous properties (volume and compliance) also increase remains unclear. Moreover, it is unknown whether

Optimization of Pre-Heat Treatment for Nitriding [PDF]
To achieve a core strength that meets the requirements during service life, components to be nitrided are subjected to a pre-heat treatment. Since a higher strength prior to nitriding also has a positive effect on the achievable strength in the nitrided layer, an optimization of the pre-heat treatment may lead to better service characteristics of ...

The evolution of a pre-heated intergalactic medium [PDF]
Abstract We analyse the evolution of the intergalactic medium by means of an extended set of large box size hydrodynamical simulations which include pre-heating. We focus on the properties of the z∼ 2 Lyman α forest and the population of clusters and groups of galaxies at z= 0. We investigate the distribution of voids in the Lyman α flux
