Abstract

Based on our previous knowledge on Cu/Nb nanoscale metallic multilayers (NMMs), Cu/WNMMs show a good potential for applications as heat skins in plasma experiments and armors, and it could be expected that the substitution of Nb byWwould increase the strength, particularly at high temperatures. To check this hypothesis, Cu/WNMMs with individual layer thicknesses ranging between 5 and 30 nm were deposited by physical vapour deposition, and their mechanical properties were measured by nanoindentation. The results showed that, contrary to Cu/Nb NMMs, the hardness was independent of the layer thickness and decreased rapidlywith temperature, especially above 200 °C. This behavior was attributed to the growth morphology of theWlayers aswell as the jagged Cu/W interface, both a consequence of the lowW adatom mobility during deposition. Therefore, future efforts on the development of Cu/Wmultilayers should concentrate on optimization of theWdeposition parameters via substrate heating and/or ion assisted deposition to increase the W adatom mobility during deposition.

Abstract

An essential condition for sustainable development and maintenance of long-term competitiveness of a company lies in the formulation of an adequate and appropriate strategy. Strategic decisions should be based on a correct understanding of the results of systematic analysis carried out by managers to form sustainable competitive advantages. The following aspects are contemplated: industry and regional conditions within the strategic areas of activity and interests of the organization, prevailing forms and types of strategic interactions, level of innovative potential of the industry and region, and specific influencing factors of macro and micro levels. However, not only the socio-economic significance (efficiency and rationality) of the decision itself is really important but also the speed, and even more precisely the timeliness of its implementation, predetermined by the dynamics of industry factors. This paper examines the relationship of innovative strategies recommended to companies with the stage of the industry life cycle, along with the specifics of territorial and regional factors. It is argued that the use of classical competition tools or the use of innovative ones, including radical strategic approaches depend on the specifics of industry and regional factors. As an example, the logic and directions of innovative solutions for an energy company are considered.

Abstract

The report presents patients with coincidence of voice disorders and rheumatoid arthritis. Material consisted of 3 females aged 39, 48 and 74 years. Methods included phoniatric examination, videolaryngoscopy, stroboscopy and acoustic voice analysis (MDVP).Results: In two youngest patients the laryngoscopic changes were located on vocal folds, mostly as a yellow nodules. The appropriate mobility of both vocal folds was found. The MDVP analysis revealed particularly changes in parameters describing perturbation of amplitude in two cases. In the third case oedema in the region of the crico-arytenoid joints and vestibular folds were observed. MDVP analysis showed slight disturbances in the parameters describing frequency perturbation.

50. Universal neonatal hearing screening - the view of parents

Author

Walczak, M, Wiskirska-Woznica, B, Karlik, M, Obrebowski, A, Wojnowski, W, and Kurywczak-Grykiel, K

Subjects

Abstract

The aim of the study was to determine the parents' view and attitude to the universal neonatal hearing screening. Parents of randomly selected 200 infants, who underwent hearing rescreening, were surveyed using the author's questionnaire. The universal neonatal hearing screening and the way it is conducted is accepted by the vast majority of the parents in the region of Wielkopolska. The parents with higher social and economic status express their negative emotions associated with the organisation of hearing screening more often, their expectations towards the system of medical care are rising.
