alpha_s was evaluated from the scaling violation of the fragmentation func tions. The data from other experiments are used for the fitting procedure.
Influence of temperature on the hydration products of low pH cements
2012
International audience; The chemical evolution of two hydrated "low pH" binders prepared from binary (60% Portland cement + 40% silica fume) or ternary (37.5% Portland cement +32.5% silica fume + 30% fly-ash) mixtures was characterized over one year at 20 degrees C. 50 degrees C, and 80 degrees C. The main hydrates were Al-substituted C-S-H. Raising the temperature from 20 to 80 degrees C caused a lengthening and cross-linking of their silicate chains. Ettringite that formed in pastes stored at 20 degrees C was destabilized. Only traces of calcium sulfate (gypsum and/or anhydrite) reprecipitated after one year in some materials cured at 50 degrees C and 80 degrees C. The sulfates released w…
Modifiable Lifestyle Factors and Cognitive Function in Older People: A Cross-Sectional Observational Study
2019
Background: The development of evidence-based interventions for delaying or preventing cognitive impairment is an important challenge. Most previous studies using self-report questionnaires face problems with reliability and consistency due to recall bias or misclassification among older people. Therefore, objective measurement of lifestyle components is needed to confirm the relationships between lifestyle factors and cognitive function. Aims: The current study examined the relationship between lifestyle factors collected with wearable sensors and cognitive function among community-dwelling older people using machine learning. Methods: In total, 855 participants (mean age: 73.8 years) wore…
From Cottesloe (1961) to Trondheim (2016): The journey of the Dutch Reformed Church back into the ecumenical family of the World Council of Churches
2018
This article presents an analysis of the journey of the Dutch Reformed Church (South Africa) back into the ecumenical fellowship of the World Council of Churches (WCC). The first part contains a brief historical review of the relationships between the WCC and the Dutch Reformed Church family, underlining the fact that the Dutch Reformed Church family in South Africa is a founding member of WCC and that it was never excluded from WCC fellowship; rather, this church itself resigned membership in the WCC after the Cottesloe Consultation (1961) at the pressure of the South African government of that time. The last part presents in detail the process of the readmission of the Dutch Reformed Chur…
A broadband spectral analysis of 4U 1702-429 using XMM-Newton and BeppoSAX data
2018
Most of the X-ray binary systems containing neutron stars classified as Atoll sources show two different spectral states, called soft and hard. Moreover, a large number of these systems show a reflection component relativistically smeared in their spectra, which gives information on the innermost region of the system. Our aim is to investigate the poorly studied broadband spectrum of the low mass X-ray binary system 4U 1702-429, which was recently analysed combining XMM-Newton and INTEGRAL data. The peculiar value of the reflection fraction brought us to analyse further broadband spectra of 4U 1702-429. We re-analysed the spectrum of the XMM-Newton/INTEGRAL observation of 4U 1702-429 in the…
Prospects for quarkonium studies at the high-luminosity LHC
2020
Prospects for quarkonium-production studies accessible during the upcoming high-luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed. Current experimental and theoretical open issues in the field are assessed together with the potential for future studies in quarkonium-related physics. This will be possible through the exploitation of the huge data samples to be collected in proton-proton, proton-nucleus and nucleus-nucleus collisions, both in the collider and fixed-target modes. Such investigations include, among others, those of: (i) J/psi and Upsilon produced in association with other hard particles; (ii) chi(c,b) and eta(c,b) down to small transverse mom…
Luokasta utopiaan : Erik Olin Wrightin myöhäistuotannosta
2020
Katsausartikkelissa tarkastellaan yhdysvaltalaisen marxilaissosiologi Erik Olin Wrightin niin sanottuihin todellisiin utopioihin kohdistunutta tutkimusta. Artikkelissa avataan sekä sitä, kuinka Wrightin todellisen utopian käsite tulisi ymmärtää, että sitä, kuinka hänen oma utopiansa eli ”sosiaalinen sosialismi” voisi olla mahdollinen ja millaiset tosimaailman kokeilut hänen mukaansa ennakoivat ja prefiguroivat tätä utopiaa. Lisäksi artikkelissa eritellään Wrightin käsityksiä antikapitalismin strategioista ja näiden myötä siitä, millä tavalla sosiaalisen sosialismin utopia olisi saavutettavissa. Artikkeli keskittyy erityisesti kahteen Wrightin myöhäistuotannon teokseen – Envisioning Real Uto…
Expression of angiogenic regulators, VEGF and leptin, is regulated by the EGF/PI3K/STAT3 pathway in colorectal cancer cells.
2009
Both leptin and vascular endothelial growth factor (VEGF) are growth and angiogenic cytokines that are upregulated in different types of cancer and have been implicated in neoplastic progression. Here we investigated the molecular mechanism by which leptin and VEGF expression are regulated in colon cancer by epidermal growth factor (EGF). In colon cancer cell line HT-29, EGF induced the binding of signal transducer and activator transcription 3 (STAT3) to STAT3 consensus motifs within the VEGF and leptin promoters and stimulated leptin and VEGF mRNA and protein synthesis. All these EGF effects were significantly blocked when HT-29 cells were treated with an inhibitor of the phosphoinositide…
A few remarks on the Inedita Pseudo-Chrysostomic Homily De transfiguratione et eleemosyna (CPG 5009; BHGn 1996t)
2021
The article presents the preliminary results of the author’s study of the unedited homily De transfiguratione et eleemosyna (CPG 5009; BHGn 1996t), ascribed to John Chrysostom. The question of the manuscript tradition is first discussed. The article shows that Maurice Sachot is right when he indicates only the manuscript Romanus Angelicus gr. 125 (T.1.7) as a manuscript witness of this homily and that the other two witnesses indicated by Pinakes are erroneous. Then, the descriptions of the folios that preserve the homily are analysed in the light of a new examination of them. This re-examination shows that hitherto several sources that inspired the compiler have gone unnoticed. This is foll…
