Wood Ash Effects on Soil Fauna and Interactions with Carbohydrate Supply: A Minireview
2011
Wood ash effects on soil animals in a boreal forest ecosystem are reviewed focusing on recent results on interactive effects of wood ash and organic amendments, and laboratory microcosms as a tool to understand soil food webs are discussed. Loose wood ash can reduce the populations of enchytraeids, collembolans and mites, but increase nematode populations particularly in experimental laboratory ecosystems with little or no primary production. Recent studies indicate that the repressive effect on enchytraeids depends on carbon availability. Carbohydrate supply seemed to alleviate the negative wood ash effect on enchytraeid body size and abundance. The fact that carbon alleviated wood ash eff…
The Role of Linguistic Resources in the Institutional Organisation of the Armenian Diaspora in Finland
2019
This chapter presents a linguistic ethnographic case study exploring the role of linguistic resources in the institutional organisation of the Armenian diaspora within the Finnish context. Even though the Armenian diasporas across the globe have been extensively studied in various countries, relatively little research has been conducted on linguistic resources employed in the institutional organisation of the Armenian diasporas. In addition, to our knowledge, no single research has focused on the Armenian diaspora residing in Finland or organisational work done at the institutional level within the Finnish context. The study reported here attempts to address these gaps by drawing upon multi…

MOJAVE VII. Blazar jet acceleration
2012
We discuss acceleration measurements for a large sample of extragalactic radio jets from the Monitoring Of Jets in Active Galactic Nuclei with VLBA Experiments (MOJAVE) program, which studies the parsec-scale jet structure and kinematics of a complete, flux-density-limited sample of active galactic nuclei (AGNs). Accelerations are measured from the apparent motion of individual jet features or "components" which may represent patterns in the jet flow. We find that significant accelerations are common both parallel and perpendicular to the observed component velocities. Cone search capability for table J/ApJ/706/1253/agn (Positions for AGN sources)
YSOs in DROXO (Deep rho Oph XMM obs.)
2011
X-rays from very young stars are powerful probes to investigate the mechanisms at work in the very first stages of the star formation and the origin of X-ray emission in very young stars. We present results from a 500ks long observation of the rho Ophiuchi cloud with a XMM-Newton large program named DROXO, aiming at studying the X-ray emission of deeply embedded young stellar objects (YSOs). Cone search capability for table J/A+A/519/A34/tablea1 (List of sources detected in the DROXO EPIC images) Cone search capability for table J/A+A/519/A34/tablea3 (ISOCAM YSOs (Bontemps et al. 2001, J/A+A/372/173) undetected in the DROXO field of view)
Chandra X-ray observation of Gum 31
2014
Gum 31 is a prominent, but still rather poorly studied HII region around the stellar cluster NGC 3324 at the northwestern periphery of the Carina nebula complex. Our aim was to reveal and characterize the young stellar population in Gum 31. An X-ray survey is the only efficient way to identify young stars in this region with extremely high galactic field-star contamination that can avoid the strong biases of infrared excess selected samples of disk-bearing young stars. We used the Chandra observatory to perform a deep (70ks) X-ray observation of the Gum 31 region and detected 679 X-ray point sources. This extends and complements the X-ray survey of the central Carina nebula regions performe…
XMM Optical Monitor Survey of TMC
2007
The Optical Monitor (OM) on-board XMM-Newton obtained optical/ultraviolet data for the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), simultaneously with the X-ray detectors. With the XEST OM data, we study the optical and ultraviolet properties of TMC members, and to perform correlative studies between the X-ray and OM light curves. In particular, we aim to determine whether accretion plays a significant role in the optical/ultraviolet and X-ray emissions. The Neupert effect in stellar flares is also investigated. Coordinates, average count rates and magnitudes were extracted from OM images, together with light curves with low time resolution (a few kiloseconds). For a fe…
MOJAVE. XIII. New 15GHz observations on 1994-2013
2017
We present 1625 new 15GHz (2cm) VLBA images of 295 jets associated with active galactic nuclei (AGNs) from the MOJAVE and 2cm VLBA surveys, spanning observations between 1994 August 31 and 2013 August 20. For 274 AGNs with at least 5 VLBA epochs, we have analyzed the kinematics of 961 individual bright features in their parsec-scale jets. A total of 122 of these jets have not been previously analyzed by the MOJAVE program. In the case of 451 jet features that had at least 10 epochs, we also examined their kinematics for possible accelerations. At least half of the well-sampled features have non-radial and/or accelerating trajectories, indicating that non-ballistic motion is common in AGN je…
Child-centred curriculum leadership for the subject of English in Ethiopian primary schools
2017
According to Serbessa (2006) there is a tension between Western pedagogy, in particular child-centred learning, and traditional Ethiopian approaches to teaching. In this study, this tension is examined through the teaching methods used and the resources teachers have at their disposal. The teachers are herein viewed as curriculum leaders, contrasting with the preconception that managers are leaders of a curriculum (Hannay & Seller, 1991). By adopting the educator’s perspective, leadership will be explored from the position of how teachers apply the English syllabus under a curriculum demanding child-centred learning, when teaching English in a state and private international school. Compari…
