Synthesis, X-Ray Structure, Tautomerism Aspect, and Chemical Insight of The 3-(1H-Indol-2-yl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-6-ol
2021
The 3-(1H-indol-2-yl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-6-ol 2 was obtained exclusively in the enol configuration starting from triazolyl-indole derivative 1 and alkyl halo-esters in the presence of K2CO3. Chemical structure elucidations with the aid of physicochemical characterizations were used to predict its molecular structure while single crystal X-ray diffraction technique was used to shed the light on the supramolecular structure of 2. DFT calculations agreed very well with the reported X-ray structure where the most stable form thermodynamically is the enol form. Its optimized geometry agreed very well with the experimental structure where the correlation coefficients betwe…
Trollaaminen ja sen vaikutukset Facebookissa
2017
Trollaaminen on aktiviteetti, mitä tapahtuu sosiaalisessa mediassa ja se yhidstetään pääosin haitalliseen toimintaan. Suurinosa trollauksesta tapahtuu anonymiteetin turvin, mutta joskus trolli saattaa toimia myös omalla identiteetillään. Trollauksen vaikutukset uhriin voivat vaihdella lievistä ärsytyksen tunteista paljon vakavampiin vaikutuksiin, kuten itsensä vahingoittamiseen tai itsemurhaan. Kun trollausta tapahtui enimmäkseen chat-huoneissa, missä lukijakunta oli rajoittunut, trollausta ei otettu vakavasti. Sosiaalisen median yleistyessä trollaus levisi myös, jolloin se mahdollisti trollauksen näkyvyyden suuremmalle lukijakunnalle. Nykyään trollaamiseen suhtaudutaan vakavammin ja jopa K…
Land surface temperature and evapotranspiration estimation in the Amazon evergreen forests using remote sensing data
2019
Amazonian tropical forests play a significant role in global water, carbon and energy cycles. Considering the relevance of this biome and the climate change projections which predict a hotter and drier climate for the region, the monitoring of the vegetation status of these forests becomes of significant importance. In this context, vegetation temperature and evapotranspiration (ET) can be considered as key variables. Vegetation temperature is directly linked with plant physiology. In addition, some studies have shown the existing relationship between this variable and the CO2 absorption capacity and biomass loss of these forests. Evapotranspiration resulting from the combined processes of …
The Aqua-Planet Experiment (APE): CONTROL SST Simulation
2013
Climate simulations by 16 atmospheric general circulation models (AGCMs) are compared on an aqua-planet, a water-covered Earth with prescribed sea surface temperature varying only in latitude. The idealised configuration is designed to expose differences in the circulation simulated by different models. Basic features of the aqua-planet climate are characterised by comparison with Earth. The models display a wide range of behaviour. The balanced component of the tropospheric mean flow, and mid-latitude eddy covariances subject to budget constraints, vary relatively little among the models. In contrast, differences in damping in the dynamical core strongly influence transient eddy amplitudes…
Is personality related to permanent earnings? Evidence using a twin design
2018
Using twin survey combined with register-based panel data on labor market outcomes, the authors examine the association between personality characteristics and long-term earnings among prime working-age individuals. The long-term earnings were measured over the 1990–2008 period. The sample contains 4,642 twin pairs, of which 53% are females. In contrast to previous studies, this paper uses the within-twin dimension of the data to control for shared family background and confounding genetic factors. The results suggest that unobserved genetic differences may introduce omitted variable bias in standard ordinary least square results. After controlling for shared environment and genetic backgro…
Using FaceReader to recognize emotions during self-assessment relating to dyslexia
2016
FaceReader ohjelman käyttö emootioiden tunnistamiseen lukihäiriöön liittyvän itse-arvioinnin aikana. Tämä pro gradu tutkielma tarkasteli kasvojen tunnistamis-ohjelma FaceReaderin käytettävyyttä tunteiden tunnistamisessa lukivaikeustaustaisilla henkilöillä heidän täyttäessään tietokone-avusteisesti itse-arviointikyselyitä resilienssiin, itsetuntoon, coping-keinoihin, sosiaaliseen kompetenssiin, attribuutioon, välttämiskäyttäytymiseen sekä terveystapoihin liittyen. Osallistujat (N=45, 17 naista / 28 miestä) olivat saaneet lukivaikeus-diagnoosin ja olivat olleet lapsena Niilo Mäki Instituutin asiakkaita. Osallistujat kutsuttiin seurantatutkimuksiin ja haastatteluihin 20 -39 -vuoden ikäisinä. L…
Effect of the extensional flow on the properties of oriented nanocomposite films for twist wrapping
2011
In this study, we examined the mechanical behavior of nanocomposite films based on polyethylene (PE) and pristine PE films. The films were prepared by film blowing and were then cold-drawn at low temperature. The experimental results show that cold drawing significantly enhanced the orientation; with increasing draw ratio (DR), the elastic modulus and tensile strength of the PE films strongly increased, particularly in the presence of the organoclay. To obtain polymeric films suitable for twist wrapping, the films must be sufficiently stiff so that no shrinkage or elastic recovery occur during or after twisting. The elongation at break and the yield strain sharply decreased with orientation…

Search for photons with energies above 1018 eV using the hybrid detector of the Pierre Auger Observatory
2017
A search for ultra-high energy photons with energies above 1 EeV is performed using nine years of data collected by the Pierre Auger Observatory in hybrid operation mode. An unprecedented separation power between photon and hadron primaries is achieved by combining measurements of the longitudinal air-shower development with the particle content at ground measured by the fluorescence and surface detectors, respectively. Only three photon candidates at energies 1-2 EeV are found, which is compatible with the expected hadron-induced background. Upper limits on the integral flux of ultra-high energy photons of 0.027, 0.009, 0.008, 0.008 and 0.007 km-2 sr-1 yr-1 are derived at 95% C.L. for ener…
