Do R&D intensity and capacity utilisation matter for SMEs' innovations within the CEE region? Testing moderating roles of different ownership structures.

Existing innovation literature has assumed that the relationship between firms' R&D intensity and innovation take place without the interplay of other organizational factors. However, the reality differs, and research to date has shown that other factors affecting firms' innovation need to be considered. This is important especially in Central and Eastern Europe (CEE) countries, which are highly dependent on both internal and external R&D and are associated with an inability to use R&D resources effectively.

The role of foreign technologies and R&D in innovation processes within catching-up CEE countries.

Prior research showed that there is a growing consensus among researchers, which point out a key role of external knowledge sources such as external R&D and technologies in enhancing firms´ innovation. However, firms´ from catching-up Central and Eastern European (CEE) countries have already shown in the past that their innovation models differ from those applied, for example, in Western Europe. This study therefore introduces a novel two-staged model combining artificial neural networks and random forests to reveal the importance of internal and external factors influencing firms´ innovation performance in the case of 3,361 firms from six catching-up CEE countries (Czech Republic, Slovakia, Poland, Estonia, Latvia and Lithuania), by using the World Banks´ Enterprise Survey data from 2019.

[Repeated action of hyperbaria on rat blood system].

There are considered reactions of male Wistar rat blood system to repeated action of nitrogen-oxygen hyperbaria (pressure 0.5 MPa, density of gas medium 6 g/l, pO2 = 0.02-0.

[Hyperbaria and stress].

Causes of the appearance of stress-reaction at action of hyperbaira on the organism were studied on rats. It has been established that at the 5-h action of gas mixtures (oxygen-nitrogen and oxygen-argon) under pressure 0.35 and 0.

Responses of constantly firing motor units to afferent stimulation.

Constantly firing motor units of the short abductor muscles of the first finger in the human hand and the abdominal wall muscle in immobilized rats responded to afferent stimulation of the median and sciatic nerves respectively with changes in the nature of spike activity. In the first 250 msec of the post-stimulus period, the frequency of motor unit spike activity became unstable and peri-stimulus histograms were individually quite distinct. This was followed by relative stabilization of motor unit discharge frequencies, and the subsequently (750 msec) determined motor unit spike frequency depended on most cases on the background spike frequency.
