Functional electrical impedance tomography (EIT) measures relative impedance change that occurs in the chest during a distinct observation period and an EIT image describing regional relative impedance change is generated. Analysis of such an EIT image may be erroneous because it is based on an impedance signal that has several components. Most of the change in relative impedance in the chest is caused by air movement but other physiological events such as cardiac activity change in end expiratory level or pressure swings originating from a ventilator circuit can influence the impedance signal. We obtained EIT images and signals in spontaneously breathing healthy adults, in extremely prematurely born infants on continuous positive airway pressure and in ventilated sheep on conventional mechanical or high frequency oscillatory ventilation (HFOV). Data were analyzed in the frequency domain and results presented after band pass filtering within the frequency range of the physiological event of interest. Band pass filtering of EIT data is necessary in premature infants and on HFOV to differentiate and eliminate relative impedance changes caused by physiological events other than the one of interest.

Ezen kutatási tanulmány módszertani összefoglalója a Kutatási és fejlesztési tevékenység lehetőségei és korlátai a KKV szektorban című kutatási műhely tanulmányainak. A kutatók feltáró, kvalitatív kutatás végeztek, azon belül pontosabban kvalitatív mélyinterjúkon alapuló esettanulmányos kutatást. A kutatók 14 kis- és középvállalkozás vezetőjével készítettek mélyinterjút annak érdekében, hogy feltárják a kis- és középvállalkozások adaptációs és növekedési lehetőségeit és korlátait, valamint az innovációs tevékenységének lehetőségeit és korlátait. Jelen tanulmány röviden bemutatja a vizsgált 14 esetet is. / === / This research paper is the methodological summary of the research working papers entitled Opportunities and constraints in the R&D activities of the SMES. The researchers carried out an explorative, qualitative research, to be more exact a case study research based on qualitative interviews. The researchers conducted interviews with CEOs of 14 SMEs in order to explore the opportunities and constraints in the adaptation and growth potential and in the innovation activities of the SMEs. This paper introduces in brief the analysed 14 case study, too.

The use of planktonic foraminifera in paleoceanographic studies relies on the assumption that morphospecies represent biological species with ecological preferences that are stable through time and space. However, genetic surveys unveiled a considerable level of diversity in most morphospecies of planktonic foraminifera. This diversity is significant for paleoceanographic applications because cryptic species were shown to display distinct ecological preferences that could potentially help refine paleoceanographic proxies. Subtle morphological differences between cryptic species of planktonic foraminifera have been reported, but so far their applicability within paleoceanographic studies remains largely unexplored. Here we show how information on genetic diversity can be transferred to paleoceanography using Globorotalia inflata as a case study. The two cryptic species of G. inflata are separated by the Brazil-Malvinas Confluence (BMC), a major oceanographic feature in the South Atlantic. Based on this observation, we developed a morphological model of cryptic species detection in core top material. The application of the cryptic species detection model to Holocene samples implies latitudinal oscillations in the position of the confluence that are largely consistent with reconstructions obtained from stable isotope data. We show that the occurrence of cryptic species in G. inflata, can be detected in the fossil record and used to trace the migration of the BMC. Since a similar degree of morphological separation as in G. inflata has been reported from other species of planktonic foraminifera, the approach presented in this study can potentially yield a wealth of new paleoceanographical proxies.
