The basic structure of the letters, especially of lines or "I"s, is clearly transferred by the projection system.
A realistic description of the photoresist processing requires the modeling of the photoresist chemistry.

The vitrified bond wheel manufacturer can impart a suitable porosity and structure to the wheel to meet the productivity requirements of the given application.
Another attribute of CBN crystals pertains to its color - an indication of the chemistry and the crystal growth process - and its likely compatibility with a vitrified bond.

Bultan 3 1 Istanbul University, Faculty of Dentistry, Department of Fixed Prosthodontics, Istanbul, Turkey 2 Yıldız Technical University, Chemistry-Metallurgical Faculty, Metallurgical and Material Engineering Department 3 Istanbul University, Faculty of Dentistry, Department of Fixed Prosthodontics, Istanbul, Turkey Keywords: dental porcelain, roughness, hardness, surface treatments, polishing Abstract.Traditionally, glazing has always been advocated as the last surface treatment before final cementation.
Roughness created by adjusting the porcelain must be smoothed to render the surface acceptable to the patient, make it less likely to abrade opposing tooth structure or restorative materials [4,12-14] and to accelerate plaque accumulation [2,15].

A VIRTUAL LD-STEEL-CONVERTER 1Mária Z.Benk�, 2George Kaptay University of Miskolc, LIMOS R&D Group Hungary 3515, Miskolc, Egyetemvaros 1 Department of Quality Assurance, 2Department of Physical Chemistry Keywords: steel metallurgy, oxygen steel making, static model, material balance, heat balance Abstract.
The following two stages of model-building can be distinguished: i. development of the general model structure of the given process (oxygen steelmaking, in general), ii. model-adaptation, i.e. determination of the values of those semi-empirical parameters, what make the general model applicable to the given device and industrial practice (for the particular oxygen steelmaking process).
