Income and Mental Well-Being : Personality Traits as Moderators
2020
Using data from the participants of the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS) at ages 42 and 50 (N = 326), this study provides empirical evidence of the relation between income and mental well-being and of the possible role of personality traits in modifying this relation. The relationships were analyzed using pooled ordinary least squares (OLS; bi- and multivariate settings) and fixed effects estimations (FE; multivariate settings). Positive bivariate associations were found between gross monthly income and the sum score of mental well-being and its separate dimensions (emotional, psychological, and social well-being and the absence of depression) as wel…
Extracellular Vesicles as Shuttles of Tumor Biomarkers and Anti-Tumor Drugs
2014
Extracellular vesicles (EV) include vesicles released by either normal or tumor cells. EV may exceed the nanometric scale (microvesicles), or to be within the nanoscale, also called exosomes. Thus, it appears that only exosomes and larger vesicles may have the size for potential applications in nanomedicine, in either disease diagnosis or therapy. This is of particular interest for research in cancer, also because the vast majority of existing data on EV are coming from pre-clinical and clinical oncology. We know that the microenvironmental features of cancer may favor cell-to-cell paracrine communication through EV, but EV have been purified, characterized, and quantified from plasma of tu…
Comparative histological and immunohistochemical study of ameloblastomas and ameloblastic carcinomas
2017
Background This study aimed to compare the histological and immunohistochemical characteristics of ameloblastomas (AM) and ameloblastic carcinomas (AC). Material and Methods Fifteen cases of AM and 9 AC were submitted to hematoxilin and eosin (H&E) and immunohistochemical analysis with the following antibodies: cytokeratins 5,7,8,14 and 19, Ki-67, p53, p63 and the cellular adhesion molecules CD138 (Syndecan-1), E-cadherin and β-catenin. The mean score of the expression of Ki-67 and p53 labelling index (LIs) were compared between the groups using the t test. A value of p<0.05 was considered to be statistically significant. Results All cases were positive for CKs 5, 14 and 19, but negative fo…
High-Sensitivity Whispering Gallery Mode Humidity Sensor Based on Glycerol Microdroplet Volumetric Expansion
2021
We demonstrate a highly sensitive whispering gallery mode (WGM) relative humidity (RH) sensor based on a glycerol microdroplet. WGMs were excited using a 760 nm tunable semiconductor laser. We used free space coupling, which is effective when using a liquid resonator. A detailed analysis of different parameters influencing the sensor’s characteristics (sensitivity, hysteresis, resolution, stability, and temperature) is presented. The sensitivity of the sensor is one of the highest reported (2.85 nm/% RH in the range 50–70% RH with the resolution 1 × 10−4% RH). This type of humidity sensor has several advantages, such as high sensitivity, extended lifetime, good repeatability, and low cost, …
Lasten tunnetaidot päiväkodissa : 5-vuotiaat ja Tunnemuksu-ohjelma
2013
Tunteet ovat muodossa tai toisessa jatkuvasti läsnä ihmisten välisessä vuorovaikutuksessa. Ne vaikuttavat moniin kognitiivisiin toimintoihin sekä sosiaalisen elämämme sujuvuuteen. Hyvät tunnetaidot suojaavat monilta elämän riskitekijöiltä ja päivähoidolla on havaittu olevan vahva rooli näiden tunnetaitojen kehittymisessä. Tämä etnografista tutkimusotetta soveltava tapaustutkimus luo silmäyksen 5-vuotiaiden lasten tunnetaitoihin päivähoidon arjessa. Tavoitteena oli saada tietoa varhaiskasvatusikäisten lasten tunnetaidoista ja siitä, miten tunnetaitojen kehittymistä voi päiväkodissa tukea Tunnemuksu ja Mututoukka -tunnetaito-ohjelman avulla. Tutkimuksen aineisto kerättiin 20 viisivuotiaan lap…
Electronic Energy Meter Based on a Tunnel Magnetoresistive Effect (TMR) Current Sensor
2017
In the present work, the design and microfabrication of a tunneling magnetoresistance (TMR) electrical current sensor is presented. After its physical and electrical characterization, a wattmeter is developed to determine the active power delivered to a load from the AC 50/60 Hz mains line. Experimental results are shown up to 1000 W of power load. A relative uncertainty of less than 1.5% with resistive load and less than 1% with capacitive load was obtained. The described application is an example of how TMR sensing technology can play a relevant role in the management and control of electrical energy.
Miten tuulivoimaloiden rakentaminen vaikuttaa paikallisten tuulivoima-asenteisiin? : esimerkkinä Luhangan Latamäki
2015
Energiantuotantoa fossiilisilla polttoaineilla pyritään korvaamaan uusiutuvalla energialla ilmastonmuutoksen hillitsemiseksi. EU:n ja valtion tasolla asetettuihin päästövähennys-tavoitteisiin päästäkseen Suomi pyrkii muiden keinojen ohella lisäämään tuulivoimalla tuotetun sähkön määrää tuntuvasti. Tuulivoimatuotannon negatiiviset ympäristövaikutukset ovat paikallisia, minkä vuoksi paikallistason suhtautuminen tuulivoimaa ja tuulivoima-puistoja kohtaan on merkittävässä roolissa tuulivoimapuistohankkeiden etenemisen vauhdittamisessa tai hidastamisessa. Luhangan Latamäkeen rakennettiin Keski-Suomen ensimmäinen kuuden 3 MW turbiinin tuulivoimapuisto vuonna 2014. Paikallisten suhtautumista tuuli…

Patterning of supported gold monolayers via chemical lift-off lithography
2017
The supported monolayer of Au that accompanies alkanethiolate molecules removed by polymer stamps during chemical lift-off lithography is a scarcely studied hybrid material. We show that these Au–alkanethiolate layers on poly(dimethylsiloxane) (PDMS) are transparent, functional, hybrid interfaces that can be patterned over nanometer, micrometer, and millimeter length scales. Unlike other ultrathin Au films and nanoparticles, lifted-off Au–alkanethiolate thin films lack a measurable optical signature. We therefore devised fabrication, characterization, and simulation strategies by which to interrogate the nanoscale structure, chemical functionality, stoichiometry, and spectral signature of t…
