Volumes of aqueous block copolymers based on poly(propylene oxides) and poly(ethylene oxides) in a large temperature range: A quantitative description
2006
The focus of this paper was on a quantitative comprehension of temperature effect on the volumes of aqueous di-block and triblock copolymers, based on propylene oxide (PO) and ethylene oxide (EO) units. To this purpose, literature data dealing with (EO316PO94 + water) and (EO13PO30EO13 + water) mixtures were analyzed. The volume vs. temperature trends were rationalized on the basis of the (unimers + aggregate) equilibrium by taking into account the temperature effect on both the partial molar volumes of the unimeric and the aggregated copolymer as well as the equilibrium constant of micellization. The analysis extended to the expansibility allowed to quantify the contribution for the shift …
Onko urbanisaatio maaseudun turma? : kaupunkien väestönkasvun vaikutukset erityyppisen maaseudun väestökehitykseen Suomessa ajanjaksolla 1990-2015
2018
Kaupungistuminen on edennyt nopeasti Suomessakin, ja samalla maaseutu on menettänyt väestöään ja aktiviteettejaan. Miten urbanisaation eteneminen on vaikuttanut maaseudun kehitykseen? Artikkelin mukaan urbanisaatio levittää kaupunkien ympäristöön sekä ”varjoa” että ”valoa”, mutta ydinmaaseudun ja harvaan asutun maaseudun negatiiviseen kehitykseen se ei ole vaikuttanut. peerReviewed
The mechanically based non-local elasticity: an overview of main results and future challenges
2013
The mechanically based non-local elasticity has been used, recently, in wider and wider engineering applications involving small-size devices and/or materials with marked microstructures. The key feature of the model involves the presence of non-local effects as additional body forces acting on material masses and depending on their relative displacements. An overview of the main results of the theory is reported in this paper.
A New Phylogenetic Framework for the Animal-Adapted
2018
Tuberculosis (TB) affects humans and other animals and is caused by bacteria from the Mycobacterium tuberculosis complex (MTBC). Previous studies have shown that there are at least nine members of the MTBC infecting animals other than humans; these have also been referred to as ecotypes. However, the ecology and the evolution of these animal-adapted MTBC ecotypes are poorly understood. Here we screened 12,886 publicly available MTBC genomes and newly sequenced 17 animal-adapted MTBC strains, gathering a total of 529 genomes of animal-adapted MTBC strains. Phylogenomic and comparative analyses confirm that the animal-adapted MTBC members are paraphyletic with some members more closely relate…
Układ częściowy obejmujący wierzytelności zabezpieczone rzeczowo a zawieszenie egzekucji z mocy prawa
2018
Niniejsze opracowanie odnosi się do problematyki wpływu otwarcia przyspieszonego postępowania układowego z układem częściowym na postępowanie egzekucyjne dotyczące wierzytelności zabezpieczonej rzeczowo na składnikach majątku dłużnika. Zaprezentowany zostanie pogląd prawny, i jego uzasadnienie, według którego, w przypadku gdy wierzytelność zabezpieczona rzeczowo na majątku dłużnika zostaje objęta układem częściowym wówczas egzekucja co do niej ulega bezwzględnemu zawieszeniu z mocy samego prawa (ipso iure)
Hydrogels for Three-Dimensional Ionizing-Radiation Dosimetry
2021
Radiation-sensitive gels are among the most recent and promising developments for radiation therapy (RT) dosimetry. RT dosimetry has the twofold goal of ensuring the quality of the treatment and the radiation protection of the patient. Benchmark dosimetry for acceptance testing and commissioning of RT systems is still based on ionization chambers. However, even the smallest chambers cannot resolve the steep dose gradients of up to 30–50% per mm generated with the most advanced techniques. While a multitude of systems based, e.g., on luminescence, silicon diodes and radiochromic materials have been developed, they do not allow the truly continuous 3D dose measurements offered by radiation-se…
Rules of Engagement: Family Rules on Young Children’s Access to and Use of Technologies
2018
This chapter reports on a study conducted in seven countries in which young children’s (aged under 8) digital practices in the home were examined. The study explored family practices with regard to access to and use of technologies, tracing the ways in which families managed risks and opportunities. Seventy families participated in the study, and interviews were undertaken with both parents and children, separately and together, in order to address the research aims. This chapter focuses on the data relating to parental mediation of young children’s digital practices. Findings indicate that parents used a narrow range of strategies in comparison to parents of older children, primarily becau…
Underground investigation of extensive air showers spectra at high energy range of cosmic rays and other research in the Pyhäsalmi mine
2020
Abstract High energy particles reaching the Earth’s atmosphere are known as cosmic rays. As a result of interactions with nuclei of air molecules, cosmic rays induce showers of secondary particles, which can be divided into 3 components: electromagnetic, hadronic and muonic components. The Experiment with Multi Muon Array (EMMA), located at the depth of 75 m in the Pyhäsalmi mine in Finland, investigates the muonic component of the Extensive Air Showers (EAS) to deduce the direction, energy, and the mass of the primary cosmic ray particles. In this paper we give a concise description and methodology used by EMMA followed by a brief review of the C14 experiment. Finally, we review the feasib…
