Characterization and application of analysis methods for ECG and time interval variability data

Author(s) : Tikkanen, Pauli
Description : Abstract The quantitation of the variability in cardiovascular signals provides information about the autonomic neural regulation of the heart and the circulatory system. Several factors have an indirect effect on these signals as well as artifacts and several types of noise are contained in the re...

Habitat requirements of juvenile salmonids : towards ecologically-based fisheries management in boreal streams

Author(s) : Mäki-Petäys, Aki
Description : Abstract For effective management of stream salmonids, it is essential to (i) assess the productive potential of a stream in relation to species-specific habitat requirements, and to (ii) identify the key factors underlying any bottleneck periods during the life cycle of a fish. For this purpose, t...

Biocompatibility evaluation of nickel-titanium shape memory metal alloy

Author(s) : Ryhänen, Jorma
Description : Abstract The shape memory effect, superelasticity, and good damping properties, uncommon in other implant alloys, make the nickel-titanium shape memory metal alloy (Nitinol or NiTi) a fascinating material for surgical applications. It provides a possibility to make self-locking, self-expanding and ...

Heart rate variability and baroreflex sensitivity in subjects without heart disease : effects of age, sex and cardiovascular risk factors

Author(s) : Pikkujämsä, Sirkku
Description : Abstract Healthy subjects show wide interindividual variation in their heart rate behavior, but the factors affecting heart rate dynamics are not well known. This research was undertaken to evaluate heart rate variability (HRV) and baroreflex sensitivity (BRS) in a large random sample of subjec...

New heterodonor phosphine and bipyridine ligands

Author(s) : Laitinen, Riitta
Description : Abstract Twenty-seven phosphine and six bipyridine ligands were synthesised and characterized. Additionally, a new route to the family of phosphine ligands via o-thioanisyldichlorophosphine was found. The phosphine ligands contain thiomethylphenyl, methoxyphenyl, dimethylaminophenyl, pyridyl, napht...

Otitis media in children : detection of effusion and influence on hearing

Author(s) : Koivunen, Petri
Description : Abstract This study was undertaken to improve the diagnosis of otitis media and to investigate possible hearing loss caused by middle ear effusion (MEE) in small children. The accuracy of minitympanometry in detecting MEE was evaluated in 162 children. The finding was compared with the amount of e...

Some applications of RF-gradients and excitation sculpting in NMR spectroscopy

Author(s) : Heikkinen, Sami
Description : Abstract RF-gradients produced utilizing RF-field inhomogenity of conventional receiver/transmitter coil of NMR-probe can be used to mimic the effects of B0-gradients. This is done by placing long inhomogenous pulse in between two 90° pulses of appropriate phases (z-rotation cluster). B0-gradient b...

Hajautettu dokumenttien hallinta : johdatus tekstin ja dokumenttien käsittelyyn tietoverkoissa 2. uudistettu painos

Author(s) : Kuronen, Timo
Description : Alkusanat Tietoverkkojen kehittyminen on lyhyessä ajassa muuttanut suuresti vakiintuneita atk:n käyttötapoja. Päätekäyttöiset keskuskoneet ovat jääneet lähes kokonaan pois käytöstä. Tilalle ovat tulleet mikrot,työasemat, palvelimet ja tietoliikenneverkot. Tietoverkot ovat moninaisuudessaan vaikeit...
