The authors demonstrate their clinical experience in the methodology developed by them for surgical-orthodontic treatment of impacted teeth. The material is based on 34 patients - 21 women and 13 men for the period 1994 - 1997. The patients were treated by the following methodology: after surgical exposure of the impacted tooth a photo-composite devise for(More)
Digital Image Correlation (DIC) is a computer based image analysis technique utilizing random patterns, which finds applications in experimental mechanics of solids and structures. In this paper a comparative study of three simulated random patterns is done. One of them is generated according to a new algorithm, introduced by the authors. A criterion for(More)
We describe a spectral Stokesmeter: a device for fast simultaneous measurement of the four Stokes parameters of light. It consists of an original optical part, a four-channel scanning optoelectronic system, and a controlling computer system. The original optical scheme was first proposed by us. It is based on two holographic gratings, one of which is a(More)
One of the problems faced in front of industry for potting media is limited amount of quality row materials (mainly peat) for unlimited production of quality substrates in the future. The using of natural minerals for production of substrates or as amendments for existing substrates is possible solution for this problem. The natural zeolites with their(More)
Localization of IgA1,2 positive objects has been studied quantitatively in the palatine and nasopharyngeal tonsils of 20 patients with pathological recurrent tonsillitis or adenoid hyperplasia. We found expression of IgA1 and IgA2 positive objects both in the tonsillar parenchyma and epithelium with predomination of the IgA1 subclass. An attempt was made to(More)
Abstract: A vision system is applied to full-field displacements and deformation measurements in solid mechanics. A speckle like pattern is preliminary formed on the surface under investigation. To determine displacements field of one speckle image with respect to a reference speckle image, sub-images, referred to Zones Of Interest (ZOI) are considered. The(More)
The extraoral appliance which is used for the treatment of patients after teeth extraction causes problems when there is lack of cooperation on the part of the patient. The appliance we present here consists of fabricated rings with brackets for the molars, lingual semicannulas, an outer arch, a lingual arch with a palatine button. The appliance distalizes(More)
The authors propose the fabrication of activators from photopolymerizing plastic. The advantages of this method are reviewed in comparison to the classical technology for fabrication of complicated constructions from hydropolymerizing plastic: Lack of residual monomer. Simplification of technology. Significant shortening of the time necessary to obtain the(More)
