Tribological properties of thin films made by atomic layer deposition sliding against silicon
2018
Interfacial phenomena, such as adhesion, friction, and wear, can dominate the performance and reliability of microelectromechanical (MEMS) devices. Here, thin films made by atomic layer deposition (ALD) were tested for their tribological properties. Tribological tests were carried out with silicon counterpart sliding against ALD thin films in order to simulate the contacts occurring in the MEMS devices. The counterpart was sliding in a linear reciprocating motion against the ALD films with the total sliding distances of 5 and 20 m. Al2O3 and TiO2 coatings with different deposition temperatures were investigated in addition to Al2O3-TiO2-nanolaminate, TiN, NbN, TiAlCN, a-C:H [diamondlike car…
The effect of the genetic background on phage infectivity in an encapsulated host
2023
Los bacteriófagos desempeñan un papel clave en la ecología y evolución bacterianas y son potenciales antimicrobianos. Sin embargo, los factores determinantes de la especificidad fago-hospedador siguen siendo poco conocidos. Debido a la prevalencia de bacterias encapsuladas, la cápsula es la primera barrera que encuentran muchos fagos. Esta capa, normalmente de polisacáridos, puede bloquear el acceso de los fagos a los receptores de su pared celular. Para superarla, algunos fagos codifican dominios depolimerasa (Dpos) específicos en sus proteínas de unión a receptores. En este trabajo, hemos cuantificado la predictibilidad de las interacciones fago-bacteria basándonos en el tipo de locus cap…
Automatic auditory and somatosensory brain responses in relation to cognitive abilities and physical fitness in older adults
2017
AbstractIn normal ageing, structural and functional changes in the brain lead to an altered processing of sensory stimuli and to changes in cognitive functions. The link between changes in sensory processing and cognition is not well understood, but physical fitness is suggested to be beneficial for both. We recorded event-related potentials to somatosensory and auditory stimuli in a passive change detection paradigm from 81 older and 38 young women and investigated their associations with cognitive performance. In older adults also associations to physical fitness were studied. The somatosensory mismatch response was attenuated in older adults and it associated with executive functions. So…
Executive function and life-space mobility in old age
2018
Life-space assessment incorporates all movements in terms of the distance from home, the frequency of movement and the need of assistance for movement. Executive function (EF) is an important higher order cognitive ability that controls and guides people’s goal-directed actions. We examined the cross-sectional and longitudinal associations between EF and life-space mobility, and investigated if perceived walking difficulties, lower extremity performance, and transportation difficulties explain the association. Methods 157 community-dwelling persons aged 76–91 years participated in the study at the baseline, and 103 of them in 2-year follow-up study. Based on the distribution on the Trail Ma…
The combined effect of lower extremity function and cognitive performance on perceived walking ability among older people : a 2-year follow-up study
2018
Background We studied the combined effects of cognitive performance and lower extremity function on self-reported walking modifications and walking difficulty and on self-reported walking difficulty incidence over a 2-year follow-up. Methods A total of 848 community-dwelling older people aged 75-90 years participated at baseline, 816 at the 1-year follow-up, and 761 at the 2-year follow-up. Baseline lower extremity function was measured with the Short Physical Performance Battery (<10 vs. ≥10) and cognitive performance with the Mini-Mental State Examination (<24 vs. ≥24). Difficulty in walking 2 km was self-reported and categorized into no difficulties, no difficulties but walking modificat…
Effects of a multicomponent resistance-based exercise program with protein, vitamin D and calcium supplementation on cognition in men with prostate c…
2022
Objectives The aim of this preplanned secondary analysis of a 12-month randomised controlled trial was to investigate the effects of a multicomponent exercise programme combined with daily whey protein, calcium and vitamin D supplementation on cognition in men with prostate cancer treated with androgen deprivation therapy (ADT). Design 12-month, two-arm, randomised controlled trial. Setting University clinical exercise centre. Participants 70 ADT-treated men were randomised to exercise-training plus supplementation (Ex+ Suppl, n=34) or usual care (control, n=36). Intervention Men allocated to Ex + Suppl undertook thrice weekly resistance training with weight-bearing exercise training plus d…
Do mobility, cognitive functioning, and depressive symptoms mediate the association between social activity and mortality risk among older men and wo…
2013
Social activity and health correlate in old age, but less is known about what explains this association. The aim of this study was to investigate whether mobility, cognitive functioning, and depressive symptoms mediate the association between social activity and mortality risk, or whether they alternatively should be considered as prerequisites for social activity in older Finnish men and women. In 1988, 406 men and 775 women aged 65–84 years took part in face-to-face interviews about their health, socioeconomic status, and social activities. Confirmatory factor analyses were used to form latent variables describing collective and productive social activity. Latent variable models were used…

Anotācija Pētījuma mērķis bija izpētīt sakarības starp stresa pārvarēšanas pašefektivitāti, pārliecību par taisnīgu pasauli, darba zaudējuma kognitīvā novērtējuma dimensijām, sociāldemogrāfiskajiem faktoriem un depresiju 209 bezdarbnieku izlasē vecumā no 45 - 61 gadiem, un pārbaudīt, vai pastāv atšķirības pārliecību sistēmā starp bezdarbnieku grupu ar un bez depresijas simptomiem. Rezultāti parāda, ka respondentu grupām ar un bez depresijas pārliecības un kognitīvais novērtējums atšķiras . 42% no depresijas variācijas izskaidro attiecību statuss, kognitīvais zaudējuma novērtējums, personīgā pārliecība par taisnīgu pasauli un stresa pārvarēšanas pašefektivitāte. Kognitīvie faktori bezdarbnie…
Tutkimusrahoitusta ja tutkijankoulutusta uudistettava
2020
Tutkimuksen rahoituksen kohdentaminen on yksi tiedepolitiikan ikuisuuskysymyksiä. Rahoitusta ja kohdentamista sekä perustana olevia rakenteita tulee uudistaa yhteiskunnan kehityksen ja muutosten mukana. Oikeastaan tämän tulisi tapahtua muutoksia ennakoiden. Pekka Neittaanmäki luo artikkelissaan mielenkiintoisen katsauksen tutkimusrahoitukseen ja siihen liittyvään tutkijankoulutukseen. Ytimenä on tieteellisen tiedon kehitys ja erityisesti tutkimuksen painotuksen muutokset suhteessa tieteellisen idean käytännön sovellusten tuottamiseen. Tältä pohjalta kirjoittaja esittää käytännön toimia suomalaisen tutkimusrahoituksen kehittämiseksi. nonPeerReviewed
