Chitosans with various degrees of deacetylation and molecular weights their allyl substituted derivatives were obtained through a solvent-free reaction under shear deformation in an extruder. Structure physical-chemical analysis the samples carried out using nuclear magnetic resonance (NMR), ultraviolet (UV) infrared radiation (IR) spectroscopy. Photosensitive materials based on synthesized polymers successfully used for microfabrication 3D well-defined architectonic structures by laser...
The aim of the investigation was to develop a novel biodegradable material based on chitosan synthesized by solid-state technoogy, and create biocompatible three-dimensional cell-carrying scaffolds using laser stereolithography.Materials Methods.Reactive systems were developed grafted with allyl, polyethylene glycol diacrylate, photoinitiator Irgacure 2959.The structures obtained stereolithography setting LS-120 (Institute Laser Information Technologies, Russian Academy Sciences,...
Modern achievements of technical progress, in particular additive technologies (ATs) and three-dimensional printing, have been increasingly introduced neurosurgical practice. The increasing complexity surgical interventions requires thorough planning surgery a high level training young neurosurgeons. Creation full-scale models for enables visualization the anatomical region interest. Additive are especially extensively used reconstructive skull defects. ATs enable fast efficient solving...
Abstract. Paleo-anthropological research has its specificity closely related with studied objects. Their complicated shape arises from anatomical features of human skull and other skeletal bones. The degree preservation is associated the fragility palaeo-anthropological material which usually high historical scientific value. circumstances mentioned above enhance relevance photogrammetry implementation in anthropological studies. Thus, such combination methodologies up-to-date technology...
Abstract. 3D imaging techniques, which started to be exact in regard the current study with photogrammetry, have brought development of measurement method – automated digital odontometry (aDo) wider opportunities terms understanding morphological characteristics human (or, non-human) teeth and dentition. Revealing them through odontometric parameters, not as visual descriptions, it has been accepted for decades is widespread till today, methods provide various previously unattainable...
Abstract. A wide variety of methods are used in archaeological research today, including 3D imaging techniques (photogrammetry) which involved at different stages starting from explorations preceding excavation to multiple studies. The archaeologically obtained material includes anthropological findings, among odontological (related human teeth) interest as they composed resistible tissues (hence preserved well) and can serve for biological well historical interpretations. However, the...
Abstract. The study of how aircraft icing influences on aerodynamic performance is very important for developing measures and recommendation to improve flight safety. effective method processes modeling experiment in wind (aerodynamic) tunnel or water (hydrodynamic) tunnel. They allow perform experiments with a scaled model an affected by visualize the wing flow process changes caused icing. While visualization yields useful qualitative information about flow, it more retrieve quantitative...
Abstract. The aim of this study was to obtain a non-destructive three-dimensional model the ancient Egyptian mummy skeleton from collection Pushkin State Museum Fine Arts (I,1 1240). objective research possibility precise segmentation bone structures and their separation surrounding mummified soft tissues, as well reconstruction destroyed fragments according preserved shape. With help additive technology made all skeleton, including distal phalanx. digital models plastic reconstructions...
Abstract. Modern techniques of optical 3D measurements such as photogrammetry, computer tomography, laser scanning provide new possibilities for acquiring accurate 2D and data high resolution, thus creating conditions anthropological analysis. Traditional manual point can be substituted by analysis textured models, which allow to retrieve more information about studied object easily share independent The paper presents the vision-based measurement investigation needed in various...
Purpose Active employment of additive manufacturing for scaffolds preparation requires the development advanced methods which can accurately characterize morphologic structure and its changes during an interaction with substrate aqueous medium. This paper aims to use method nuclear magnetic resonance (NMR) imaging preclinical characterization 3D-printed based on novel allyl chitosan biocompatible polymer matrices. Design/methodology/approach Biocompatible were fabricated via...

The matrices were obtained using photosensitive composition allyl chitosan (5 wt%), poly(ethylene glycol) diacrylate (8 wt%) photoinitiator Irgacure 2959 (1 by laser stereolithography setting. kinetic swelling curves constructed for structures in base salt forms gravimetric method contact angles measured droplet spreading....
Abstract. The problem of facial appearance reconstruction (or approximation) basing on a skull is very important as for anthropology and archaeology forensics. Recent progress in optical 3D measurements allowed to substitute manual techniques with computer-aided ones based digital models. Growing amount data developing methods processing provide background creating fully automated technique face approximation.The performed study addressed approximation model deep learning techniques. models...
The presented paper experimentally demonstrates the potential expansion of stereolithographic prototype utilization. Two methods for manufacturing plastic prototypes are proposed, enabling subsequent substitution polymer material with either metal or ceramics. first method involves additional actions by designer during modeling stage. second necessitates alterations in technological processes model preparation and using a stereolithography apparatus. Material occurs two stages. Initially,...
