Article Highlights• Interaction of glassy carbon with Nd 3+ :YAG laser beam of various energy densities were investigated • Damage morphology analysis has shown that damage morphology depends on the energy density • The Image analysis have applied for obtaining quantitative description of the damage topology • Numerical simulation of glassy carbon interaction with laser was performed by COMSOL Multiphysics • Numerical simulation was based on thermal model and FEM method Abstract Laser beam interaction with carbon based material (glassy carbon) is analyzed in this paper. A Nd 3+ :YAG laser beam (1.06 μm, i.e., near infrared range (NIR)) in ms regime with various energy densities is used. In all experiments, provided in applied working regimes, surface damages have occurred. The results of laser damages are analyzed by light and scanning electron microscopy (SEM). Image J software is used for quantitative analysis of generated damages based on micrographs obtained by light and SEM microscopes. Temperature distribution in the exposed samples is evaluated by numerical simulations based on COMSOL Multiphysics 3.5 software in a limited energy range.Keywords: laser, interaction, glassy carbon based material, quantitative analysis, numerical simulation.Carbon based modern materials in practice can be found in a number of types [1]. Various arrangements of microstructure domains, ordered and disordered, are produced in commercial or laboratory samples, leading to design of carbon materials of different characteristics. The new technological processes make possibility for designing and producing materials with desired mechanical, thermal, electrical, and other properties [2,3]. Laser interaction with well-known graphite -and diamond-like materials remains an unresolved issue. Recently, carbon active materials, carbon nanotubes, 60 C and carbon composites, have been attracting attention. Fabrics and generally fiberCorrespondence: P. Jovanić,

Sentence structure is one of the most important components of stylistic analysis since it primarily represents textual readability and comprehensibility. Languages with predominantly strict word order, such as Swedish, show various stylistic characteristics. Stylistic analysis is affected by numerous aspects e.g. parataxis, hypotaxis, topicalization, duplication, elliptical sentences, sentence structure in formal and informal texts combined with additional syntactic features. Stylistic variations of a given text can also improve language learning. The aim of this study is to examine the most frequent examples of syntactical stylistic analysis in Swedish and to emphasize their importance for advanced language learning and translating.

Testing of materials properties is usually a discipline for the quality assurance during manufacturing processes. In condition monitoring, certification or upgrading of existing plants and in failure analysis similar benefits from nondestructive testing of materials properties can be achieved. Another benefit from the Non-Destructive Metallography (NDM) is that the test can be made on-site. NDM is a well established and proven tool to help determine the integrity of generator and hydro turbine components during their life-cycle in power plant environments. On-site metallography of components makes it possible to evaluate the microstructure of materials. It allows microstructural analysis of large components that are difficult to move or not permitted to be destructively tested, enabling rapid evaluation of the material. Here are monitored the microstructural changes and crack detection in St 35 connecting rod steel after approximately 15 years in service. The paper includes a short description of the replica method as a technique for microstructural examination of components by using non-destructive testing method.
