Cellular mechanisms of atrial mechanotransduction : interacting mechanisms in stretch-induced changes of rat atrial function and their modulation by intracellular acidosis
Author(s) :
Tavi, Pasi
Description :
Abstract
Stretch of the cardiac muscle activates several physiological
processes leading to changes in the function of the muscle. These
changes include increase of the contraction force accompanied by
changes in the intracellular calcium concentration. This phenomenon
is known as Frank-Starlin...

High resolution infrared spectroscopy on the fundamental bands of 13CH3I
Author(s) :
Alanko, Seppo
Description :
Abstract
This thesis deals with the rotation-vibration theory and high resolution infrared spectroscopy of semirigid C3 molecules. Semirigid molecules form a class of molecules which are strongly bound with one well defined structure, and without low frequency internal motions. The theory, as well ...

Studies on via coupling on multilayer printed circuit boards
Author(s) :
Tarvainen, Timo
Description :
Abstract
Design and manufacturing techniques of printed circuit boards
(PCB's) have advanced from early one or two-layer structures
to the multilayer boards where ten or more layers are no longer
uncommon. These give additional routing space, potential decrease
in device size and various design...

Mate choice and genetic variation in male courtship song in Drosophila montana
Author(s) :
Suvanto, Leena
Description :
Abstract
This thesis deals with factors affecting mate choice as well
as with genetic variation in male courtship song in Drosophila
montana. Males, which produced song with a high carrier
frequency, were found to court females, and also to succeed in
their courtship more often than the males p...

Genetic aberrations and their clinical significance in breast and ovarian cancer
Author(s) :
Launonen, Virpi
Description :
Abstract
In tumourigenesis, genetic alterations accumulate in the genes responsible for cell growth, proliferation and DNA repair: proto-oncogenes, tumour suppressor and DNA repair genes. Inactivation of tumour suppressor gene function is commonly recognised as a deletion of one of the two alleles;...

Determination of the permittivity of some dielectrics in the microwave and millimetre wave region
Author(s) :
Kemppinen, Esa
Description :
Abstract
In the first part of this study, determination of the dielectric properties of the low loss microwave ceramic material, barium nonatitanate (Ba2Ti9O20), around 1 GHz is discussed. The structures under test were coaxial resonators, the cores of which were made of barium nonatitanate and the...

Sairaalahoito astmaatikon selviytymisen kuvaajana : rekisteritutkimus sairaalahoidossa olleiden astmaatikkojen ikä- ja sukupuolijakaumasta, uusien hoitojaksojen määrästä, hoitojaksojen vuodenaikavaihtelusta lapsilla, varusmiehillä ja aikuisilla sekä kuolleisuuden vuodenaikavaihtelusta
Author(s) :
Harju, Terttu
Description :
Abstract
This thesis discusses the age and sex distribution of previously
hospitalised asthmatics and the number of new asthma-induced treatment
periods as a proportion of all asthma-related hospital admissions.
Seasonal fluctuations in treatment periods were analysed with respect
to age, and s...

The effect of impaired dentin formation on dental caries : an experimental study in the molars of growing rats
Author(s) :
Huumonen, Sisko
Description :
Abstract
The effects of dietary sucrose and systemic glucocorticoid treatment on the response
of the pulpodentinal complex to dental caries were examined in an experimental rat model. The possible role
of dentinal caries on dentin formation was also examined. After 5-6 weeks of a dietary and/or
m...

Evaporation of acidic effluent from kraft pulp bleaching, reuse of the condensate and further processing of the concentrate
Author(s) :
Dahl, Olli
Description :
Abstract
Environmental concern and tighter public regulations have created new pressures to reduce effluent loading from kraft pulp bleaching during the past decades. This trend has forced both pulp mills and the related engineering industries to develop and optimise equipment for the pulping proce...

Cardiovascular autonomic regulation in systemic hypertension
Author(s) :
Ylitalo, Antti
Description :
Abstract
Neurogenic factors are known to be important in the development of hypertension. Our current knowledge of the role of autonomic nervous system in chronic hypertension is, however, limited. The purpose of the present study was to evaluate the possible abnormalities in heart rate variability...
