The article is devoted to a pending matter in the Latvian linguistics and methodology of language and literature – the formation of the system of terminology. The 90-ies of the 20th century when Latvia gained its national independence brought changes not only in the political and economic life but also in the terminology because new realities, which appeared in life, needed new names. Essential transformation in education brought along changes in the nomination system of the specific realities in the sphere. By establishing broader contacts with the pedagogical information field of the Western countries, translating scientific articles one comes in touch with specific concepts of the sphere for which there are no matching nominative units in Latvian and, judging by publications, in most cases equivalent terms are successfully formed. Unfortunately, this is not true of all innovatons, which, due to lack of time, amount of work or other reasons, in most cases are not submitted to language experts or the terminology commission for approval. The research provides analysis of several terms used in the methodology of the Latvian language and literature, as well as other subjects, yet are contraversial from the viewpoint of terminology and the quality of the Latvian language. The research presents the analysis of the semantic structure of active teaching methods and methodological approaches in language and literature in the context of the Latvian language world view with the aim to encourage teachers, lecturers of institutions of higher education, specialists in pedagogy and didactics and other people concerned to consider whether one or another name (which can hardly be referred to as ‘term’) fits into the education process.

Tissue engineering approaches for healing cartilage defects are partly limited by the inability to fix cartilage to bone during implantation. To overcome this problem, cartilage can be - already in vitro - generated on a ceramic carrier which serves as bone substitute. In this study, the influence of a hydroxylapatite carrier and its surface structure on the quality of tissue engineered cartilage was investigated. Application of the carrier reduced significantly biomechanical and biochemical properties of the generated tissue. In addition, slight changes in the quality of the formed matrix, in the adhesive strength between cartilage and biomaterial and in attachment and proliferation of a chondrocyte monolayer could be observed for commercial grade carriers, with respect to modified topographies obtained by smooth grinding/polishing. These first results demonstrated an influence of the carrier and its surface structure, but further research is needed for explaining the described effects and for optimization of cartilage-carrier-constructs.

The Subject

The paper deals with the properties, quality and durability of the exposed concrete. The main part of this paper are characteristic of architectural (sometimes called visible or naked) concrete and the criterion of the quality evaluation of the performed work. This is mainly the colour balance of the subject area, the quantity and the size of the pores, the quality of the raw material and the surface structure. Achieving the quality of architectural concrete is considerably more technologically demanding compared with conventional concrete. This is reflected also in its cost. In conclusion, the problems of surface layers of architectural concrete are summarized. Especially environments can cause faster degradation, reducing the lifetime of the whole construction, but also pointing to one of the main problems in construction, which is technological discipline.

This article presents some possibilities of laser micro-machining. Results of the laser micro-machining surface quality of product and his utility in specific application depend on the laser parameters and the polymer material type. From the obtained scientific knowledge it follows, that the character of surface machined by laser depends on thermal conductivity of polymer. The action of laser beam is best shown on specimens from PMMA, therefore tests were carried out with this material. Optimal parameters of CO2 laser for used material are presented in given study. Visual evaluation of action laser ray on surface of PMMA was made also.

Engineering Materials

Throughout history, a substantial or often leap technological progress, was determined by the availability of new engineering materials, which usually stimulated the improvement in the quality of life. The development of engineering materials constitutes one of the most significant elements in the field of science and technology, and innovative policy in Poland and Europe as regards the knowledge-based economy (KBE). The enhancement of the product functional properties, required by the new strategies of engineering materials development, as well as materials processing technologies is frequently connected with appropriate formation of the engineering materials surface layer structure and properties. Functional properties of many products depend not only on the possibility of transferring the mechanical load across the whole element section or its physicochemical properties, but, most often, they depend mainly on the surface layer structure and properties. The application of foresight methodology in the assessment of the state and prospects regarding the development of technology related to the formation of the materials surface structure and properties provides the possibility to manage knowledge in this field. It can be achieved through a formalization of the explicit and tacit knowledge gathering and use in order to increase production competitiveness, effectiveness, and innovation, improve the quality of life and achieve sustainable development. The objectives accomplished in such a way contribute to the increase in intellectual capital by enhancing the effectiveness of using the existing knowledge, creating new knowledge, as well as increasing the level of understanding and disseminating knowledge. The implemented foresight project will result in identifying the priority innovative technologies and strategic research trends in the scope of surface structure and properties formation of engineering materials and biomaterials whose development in the country will be of key importance within next 20 years.

This study examines the composite quality of PP and HDPE plastic waste materials using Microfiber Oil palm empty fruit bunches (OPEFB) as filler, the fiber used is 90 µm. The ratio of matrix: filler used is 60:40 and 70:30 for each type of PP and HDPE polymer. The method used is a melt blending screw extruder, where plastic and fiber materials are dissolved with a compatibilizer and then melt blended in an extruder by providing temperatures of 160 and 170 oC. Tensile tests showed the strength of the PP composite with a filler ratio of 60:40 and 70:30, respectively, of 313.25 N and 336.35 N, while the HDPE composite with a filler ratio of 60:40 and 70:30, respectively are 392.93 N and 187.90 N. The maximum force required to break HDPE composites reaches 21.10 Mpa while for PP composites it reaches 18.56 Mpa. From the morphology of the PP and HDPE composite samples, the overall surface structure of HDPE looks regular with a width from 1 to 13.5 mm. The PP composite shows a uniform and regularly arranged surface structure and the bond between the fibers and the filler looks more compatible but the surface pores are rougher. Heat resistance can be seen from the melting point of PP composites which can reach 163.81oC while HDPE composites only reach 134.21oC.
