Telia Crowd Insights -tietojen hyödyntäminen pandemiatietoisuuden parantamiseksi Keski-Suomessa
2021
Telia Crowd Insights -tietojen hyödyntäminen pandemiatietoisuuden parantamiseksi KeskiSuomessa on Keski-Suomen liiton rahoittama hanke, jolla pyritään selvittämään, että pystytäänkö ihmisten ja ihmisvirtojen liikkeitä seuraamalla saavuttamaan parempi tilannekuva pandemia tilanteessa. Hankkeen tarkoituksena on keskittyä erilaisiin liikenteenseurantaratkaisuihin sekä tutkia koronaviruksen aiheuttamia vaikutuksia maakunnassa tapahtuvaan liikenteeseen ja liikkumiseen. Keväällä 2020 tuli voimaan poikkeukselliset olosuhteet, joiden takia liikenne muuttui merkittävästi erilaisten rajoitusten ja yleisen varovaisuuden vuoksi. Tämä on yksi merkittävimmistä ilmiöistä, joita projektissa pyritään tutkim…
A Thermophilic Tetramolecular G-Quadruplex/Hemin DNAzyme.
2017
International audience; The quadruplex-based DNAzyme system is one of the most useful artificial enzymes or catalysts; their unique properties make them reliable alternatives to proteins for performing catalytic transformation. The first prototype of a thermally stable DNAzyme system is presented. This thermophilic DNAzyme is capable of oxidizing substrates at high temperatures (up to 95 degrees C) and long reaction times (up to 18 h at 75 degrees C). The catalytic activity of the DNAzymes were investigated with the standard peroxidase-mimicking oxidation of 2,2'-azino-bis(3-ethylbenzothiozoline-6-sulfonic acid) (ABTS) by H2O2. The step-by-step design of this unique heat-activated G-quadrup…
Multifaceted effects of oligodendroglial exosomes on neurons: impact on neuronal firing rate, signal transduction and gene regulation.
2014
Exosomes are small membranous vesicles of endocytic origin that are released by almost every cell type. They exert versatile functions in intercellular communication important for many physiological and pathological processes. Recently, exosomes attracted interest with regard to their role in cell–cell communication in the nervous system. We have shown that exosomes released from oligodendrocytes upon stimulation with the neurotransmitter glutamate are internalized by neurons and enhance the neuronal stress tolerance. Here, we demonstrate that oligodendroglial exosomes also promote neuronal survival during oxygen–glucose deprivation, a model of cerebral ischaemia. We show the transfer from…
¿Qué pueden aportar las ciencias de la visión al diseño gráfico?
2020
[ES] El diseño gráfico es importante y necesario en el mundo de hoy porque la vista es la principal forma de adquisición de información. Por lo tanto, es lógico pensar que las ciencias de la visión pueden ayudar en la toma de decisiones a nivel de diseño. Comprender conceptos como la agudeza visual, la sensibilidad al contraste, entre otros, contribuirá a optimizar la legibilidad del texto a través de una selección óptima de parámetros tipográficos para formatos impresos y digitales. Además, entender el efecto de las diferentes alteraciones en la visión del color mejorará la accesibilidad del diseño.
Farsighted R&D networks
2014
We analyze the formation of bilateral R&D collaborations in an oligopoly when each firm benefits from the research done by other firms it is connected to. In contrast to myopic stability, farsighted stability leads to R&D networks consisting of two minimally connected components, with the largest one comprising three-quarters of firms.
Structural highs formation and their relationship to sedimentary basins in the north Sicily continental margin (southern Tyrrhenian Sea): implication…
2005
Two high-penetration seismic profiles across the continental margin of north Sicily (southern Tyrrhenian Sea) have been interpreted to construct a crustal section across the margin and to provide a three-dimensional perspective on the upper crustal setting of the Solunto High and its structural relationships with the adjacent Cefalù Basin. Crystalline rocks of the Kabilian-Calabrian Units (KCU) are recognized in the Solunto High region and farther to the north. The KCU body is tectonically superimposed onto sedimentary rocks pertaining to the Sicilian-Maghrebian Units (SMU) and the Solunto High corresponds to the thrust sheet culmination. Its occurrence in the Solunto High demonstrates that…
Las frazadas en la memoria de la dictadura chilena : el caso de Jorge Montealegre
2020
As Pia Montalva (2013) points out, the blankets are the artefacts that best represent political imprisonment and its ambiguities: on the one hand, they embody the basic functions of the technology of power in dictatorship: they take away speech and sight, immobilise the body, erase the individuality of the face and the countenance, isolate the individuals from their environment,. On the other hand, they contribute to restoring a certain normality in an exceptional situation such as that of confinement and allow the uncertainty of detention to be accepted. In Jorge Montealegre's testimony (2003) about his forced stay in the National Stadium, written thirty years after the military coup, the …
The affective impact of sightseeing bus tour experiences:using Affective Events Theory (AET) to examine length-of-stay and electronic word-of-mouth
2022
This study investigates the key components and influences of positive affect and electronic word-of-mouth (eWOM) on tourist visits at two developing urban destinations, namely Birmingham, United Kingdom and Valencia, Spain. These two data collection sites yielded evidence gathered from 627 and 615 sightseeing bus tourists, respectively. Through the analytic lens of Affective Events Theory (AET), data was examined, and results verify the significant mediating role of affect in two regards: (1) tourists’ decision to extend their visits, and (2) eWOM of sightseeing bus tour experiences. The moderating role of past sightseeing experiences in these relationships was also supported by the data an…
The 15 March 2007 explosive crisis at Stromboli Volcano, Italy: assessing physical parameters through a multidisciplinary approach
2011
Basaltic volcanoes are dominated by lava emission and mild explosive activity. Nevertheless, many basaltic systems exhibit, from time to time, poorly documented and little-understood violent explosions. A short-lived, multiblast explosive crisis (paroxysmal explosion) occurred on 15 March 2007 during an effusive eruptive crisis at Stromboli (Italy). The explosive crisis, which started at 20:38:14 UT, had a total duration of ∼5 min. The combined use of multiparametric data collected by the permanent instrumental networks (seismic, acoustic, and thermal records) and a field survey carried out immediately after the event enabled us to constrain the eruptive dynamics and quantify physical param…
X-Raying the Dark Side of Venus - Scatter from Venus Magnetotail?
2016
This work analyzes the X-ray, EUV and UV emission apparently coming from the Earth-facing (dark) side of Venus as observed with Hinode/XRT and SDO/AIA during a transit across the solar disk occurred in 2012. We have measured significant X-Ray, EUV and UV flux from Venus dark side. As a check we have also analyzed a Mercury transit across the solar disk, observed with Hinode/XRT in 2006. We have used the latest version of the Hinode/XRT Point Spread Function (PSF) to deconvolve Venus and Mercury X-ray images, in order to remove possible instrumental scattering. Even after deconvolution, the flux from Venus shadow remains significant while in the case of Mercury it becomes negligible. Since s…
