Pandemianaikaista kielipedagogiikkaa : näkökulmia maahanmuuttajien etäopetukseen
2020
The novel coronavirus pandemic forced schools to implement remote instruction during spring 2020. I studied teachers’ perceptions of the implementation of newcomer and Finnish as a second language instruction during the remote period. Survey respondents considered remote instruction a burden on both students and teachers and thought students’ unfamiliarity with educational technology presented challenges. Benefits of remote instruction included students’ increased self-directedness in learning, the use of technologies for differentiation, and an increase in collaboration with colleagues and families. nonPeerReviewed
Kohti kielitaitoista ja kielitietoista maailmankansalaisuutta : A-englannin päättöarvioinnin kriteerit käyttöön
2021
Perusopetuksen päättöarvioinnin kriteerit ovat tarkentuneet, mutta kuinka selkeitä ne ovat kieltenopettajille? Hämmennystä ovat herättäneet varsinkin A-englannin tavoitteiden T1−T5 kriteerit. Vaikka nämä ei-kielelliset tavoitteet ovat arvokkaita opetuksen sisältöjä, on vaikeaa hahmottaa, miten asettaa arvosana-asteikolle esimerkiksi englannin kielen aseman ymmärtäminen tai englanninkielisten aineistojen käyttäminen. Yritän pohtia tavoitteiden 1−5 merkitystä ja niiden arviointia oman arkeni kautta, jossa tunnen yhä enemmän olevani kasvattaja kuin opettaja. Opetan englantia ja ruotsia Iittalan yhtenäiskoulussa Hämeenlinnassa. Koulumme on pienehkön kyläyhteisön keskus, jossa kaikki tuntevat to…
Model of hydrocarbons transport through the porous ground media
2014
Dispersion model of hydrocarbons transport in porous media has been presented. Mathematical description of this process allows to estimate whether the menace of ground waters can occur as a result of hydrocarbons transport through the soil. The convection term in the mass transport equation is taken into account due to the higher velocity of propagation in vertical direction. Additionally, introduction to the balance equation the biosorption link allows to take into account microorganisms influence on impurities concentration, especially on heavy oils derived compounds. To verify the theoretical model series of the experiment in the soil filter has been carried out.
A software receiver adaptive phase lock loop method
2009
The aim of this paper is to introduce a new and relatively simple algorithm which is capable to tune the parameters of the loop filter in a phase lock loop, like the one that can be found in a global navigation satellite system receiver. The parameters are chosen while the system is running, in order to make the bandwidth of the filter adaptive with respect to the signal dynamic and strength. A wider bandwidth is obtained to make the filter more reactive when searching the carrier, while the bandwidth gets narrower when the system is in the tracking state, in order to cut off as much noise as possible. The algorithm is based on the observation of the estimated variance of the phase lock loo…
Plant Specialized Metabolites in Hazelnut (Corylus avellana) Kernel and Byproducts: An Update on Chemistry, Biological Activity, and Analytical Aspec…
2019
Abstract Corylus avellana (hazelnut) is one of the most popular tree nuts on a worldwide basis. The main products of C. avellana are kernels, a nutritious food, with a high content of healthy lipids, contained in a hard shell. In recent years, along with the ongoing research carried out on hazelnut kernels, a growing interest has been addressed to the hazelnut byproducts including hazelnut skin, hazelnut hard shell, and hazelnut green leafy cover as well as hazelnut tree leaf. These byproducts deriving from the roasting, cracking, shelling/hulling, and harvesting processes have been found as a source of “phytochemicals” with biological activity. The aim of this review is to provide a compre…

Removal of silicon from CFB-derived fly ash leachate in the context of phosphorus recovery
2018
High concentrations of dissolved silica in the acid leachate impose two major challenges on precipitation based recovery of phosphorus (P). Firstly, co-precipitation of colloidal silica in the acidic regimes decreases the purity and value of precipitated P-products. In addition, silica scaling on internal surfaces of equipment is also a problematic issue in industrial operations. Therefore, removal of dissolved silica prior to P-recovery process minimizes the risks of Si-contamination in P-products and Si-scaling. In the present study, silica removal was achieved by accelerated silica polymerization with higher acidity and ionic strength of mineral acid, which also assisted the leaching of …
Propuesta de monitorización integral de la calidad ambiental del interior de la Iglesia de los Santos Juanes de Valencia
2020
Para la correcta conservación de los bienes de interés cultural (BIC), debe existir una óptima calidad ambiental interior. La monitorización de esta calidad ambiental, tradicionalmente, incluye el estudio de la humedad y la temperatura de los espacios interiores ya que es bien conocido que sus valores elevados y fluctuaciones rápidas pueden alterar los materiales constitutivos de las obras de arte. Sin embargo, hay muchos otros parámetros que se deben estudiar para tener una visión completa de los riesgos potenciales relacionados con ambientes patrimoniales. En este trabajo, planteamos la importancia de una monitorización integral sistemática de la calidad ambiental de un bien patrimonial q…
The relationship between visible light emission and species fraction of the hydrogen ion beams extracted from 2.45 GHz microwave discharge.
2015
The relationship between Balmer-α and Fulcher-band emissions with extracted H + , H + 2 , and H + 3 ions is demonstrated for a 2.45 GHz microwave discharge. Ion mass spectra and optical measurements of Balmer-α and Fulcher-band emissions have been obtained with a Wien Filter having an optical viewport on the plasma chamber axis. The beam of approximately 1 mA is analyzed for different plasma conditions simultaneously with the measurement of light emissions both with temporal resolution. The use of visible light emissions as a valuable diagnostic tool for monitoring the species fraction of the extracted beams is proposed. peerReviewed
L’organisation des circuits courts par les intermédiaires.
2016
The dissertation deals with the institutionalisation of proximity in agri-food markets and the place occupied in this process by non-economic intermediaries (employees of associations, researchers, members of staff from the ministry of Agriculture, advisers of the chambers of agriculture). By varying the scales of investigation, from the national to the departmental level, and by articulating qualitative and quantitative methods, this work points out the paradox that constitute the development of those intermediary agents, as proximity is progressively defined and objectified as a virtuous component of the merchant relationship. On the basis of a sociology of merchant institutions attentive…
