different temperature levels was recorded by digital photography and quantified by image analysis. At the same time the thermal power of the mould sample was measured with isothermal calorimetry.
The purpose of this study is to compare these two

Neutron activation analysis, gamma-ray spectrometry, particle sizing and photography of the corrosion products were used to qualify the constructional materials and primary coolants. The investigations related to: characterization of the construction materials of the primary circuit, circulated washing, hot conditioning, physical and energetic start up. The aim of the measurements was to study the cleanness of the primary circuit from assembling up to energetic start up and to follow closely the variation in the amount and the removing of the mechanical contaminants and corrosion products depending on the technological parameters.
The oxidation in air and oxygen of iron (II) sulphide Fe1−xS was studied using TG, DTA, X-Ray powder photography and chemical analysis. A reaction sequence was deduced, in which in the temperature range 425–520‡ partial oxidation occurred forming FeSO4, FeS2, Fe3O4. Rapid oxidation to Fe2O3 was usually observed in the range 520–575‡ but under certain conditions this reaction did not occur. In the temperature range 575–625‡ oxidation of FeSO4 to [Fe2(SO4)3]2 · Fe2O3 took place. Decomposition of this material gave Fe2O3 as the final product at 725‡.

activation energy was evaluated in the premelt state for all the various chemicals studied and were defined by the overlay of DEA and DSC curves which marked the solid liquid transition. Macro photography for all the samples was recorded with a Sony
membranes that show properties of excellent blotting agents. Cellulose nitrate films became popular in the late 1880s because of their physical properties which made them ideal for photography. Into the early 1950s, cellulose nitrate films were used mostly
The cadmium(II) halides have industrial or biological importance. They are very toxic reagents that are using in metal plating, battery industry, photography, dying, and printing industries [ 1 ]. As well as
