Maahanmuuttajien kielitaito - yhteiskunnan resurssi vai yksilön kätköissä oleva pääoma? : esimerkkinä toisen polven suomenunkarilaiset

2014

The language policy of the European Union has the goal that every citizen will be bilingual and everybody will be able to communicate in two diQ erent languages besides one’s mother tongue. The aim of this article is to investigate the conditions for reaching these goals among people with immigrant backgrounds. The article provides an overview of bilingualism among one group of adults with Hungarian background in Finland. The focus is on language repertoire (e.g. the self-assessed language pro+ ciency), language choice between Finnish and Hungarian, the role of the minority language in their everyday lives and the future prospect for maintenance of Hungarian. The entire article is based on …

Nonlinear Disorder Mapping Through Three-Wave Mixing

2010

We implement a simple and powerful approach to characterize the domain distribution in the bulk of quadratic ferroelectric crystals via far-field second-harmonic spectroscopy. The approach is demonstrated in a lithium tantalate sample with periodic electric field poling and random mark-to-space ratio.

Innovative, Translucent and Multi-functional Components for the Building Envelope: technological and performance optimization

2017

The paper describes the actions aimed at the technology and performance optimization of an innovative, multi-functional building component made of precast and pre-stressed glass blocks useful for the construction of sustainable building envelopes able to reduce the energy consumption and to produce clean energy from the sun. The design optimization of different sub-components and the choice of the right materials for guaranteeing their good response in terms of mechanical resistance, thermal and acoustic insulation, light transmission, electricity production, integration with other components, dimensional coordination, are particularly described.

Direct electricity production from coconut oil - the electrooxidation of coconut oil in an acid electrolyte

2018

Supplying more and more energy is an essential task of today's energy industry. In the last few decades, in addition to traditional methods of energy production, alternative energy sources have been developing at a fast rate. One of the devices that can use these sources is the fuel cell (FC). FCs can be a power source of the future mainly due to their high efficiency, their low impact on the environment and the possibility of powering with different fuels. Most often, FCs are powered by hydrogen. However, issues with its cheap production and storage are the reasons for seeking new fuels for FCs. Yet it must be a fuel that will provide a zero or low emission level. One of these fuels can be…

Possibility of direct electricity production from waste canola oil

2017

Powering high-efficiency devices, such as fuel cells, with waste products will allow for a broader development of renewable energy sources and utilisation of by- products. This publication presents the possibility of electrooxidation of the emulsion of waste rapeseed oil, prepared on the basis of the detergent Syntanol DS-10. The process of electrooxidation was carried out on platinum electrode in alkaline (KOH) and acidic (H 2 SO 4 ) electrolyte, in the temperature range of 293-333 K. In each analysed case the process of electrooxidation took place. The maximum current density obtained was 7 mA cm -2 . Thus, it has been shown that it is possible to generate electricity directly from the em…

A Territorial Approach to the Production of Urban and Rural Landscape.

2018

The authors, starting from the examination of the historic data of Palermo landscapes on the south-east side, draws up an analysis of the landscape by illustrating the environmental characteristics and the intervention of man in its transformations. Therefore, determined by a certain point to refer to, the author, on the basis of archival, literary, and existing graphic documentation, has therefore sought to illustrate the evolution of the landscape in the geographical area of Maredolce while still presenting relations with the territory of Palermo. Examining the diaries at the end of the eighteenth century with the help of the water colored planks of the sites taking into account the great…

Performance Improvement of a Drag Hydrokinetic Turbine

2021

Hydropower is at present in many locations, among all the other possible renewable energy sources, the best one for net cost per unit power. In contrast to traditional installation, based on water storage in artificial basins, free flow river turbines also provide a very low environmental impact due to their negligible effect on solid transport. Among them, kinetic turbines with vertical axis are very inexpensive and have almost zero impact on fish and local fauna. In application to tidal waves and sea waves, where vertically averaged velocities have alternate direction, a Savonius rotor also has the advantage of being productive during the whole time cycle. In this work, the effect of an u…

Macrophages as an Emerging Source of Wnt Ligands: Relevance in Mucosal Integrity

2019

The Wnt signaling pathway is a conserved pathway involved in important cellular processes such as the control of embryonic development, cellular polarity, cellular migration, and cell proliferation. In addition to playing a central role during embryogenesis, this pathway is also an essential part of adult homeostasis. Indeed, it controls the proliferation of epithelial cells in different organs such as intestine, lung, and kidney, and guarantees the maintenance of the mucosa in physiological conditions. The origin of this molecular pathway is the binding between Wnt ligands (belonging to a family of 19 different homologous secreted glycoproteins) and their specific membrane receptors, from …

Alzheimer's disease: new diagnostic and therapeutic tools.

2008

Abstract On March 19, 2008 a Symposium on Pathophysiology of Ageing and Age-Related diseases was held in Palermo, Italy. Here, the lectures of M. Racchi on History and future perspectives of Alzheimer Biomarkers and of G. Scapagnini on Cellular Stress Response and Brain Ageing are summarized. Alzheimer's disease (AD) is a heterogeneous and progressive neurodegenerative disease, which in Western society mainly accounts for clinica dementia. AD prevention is an important goal of ongoing research. Two objectives must be accomplished to make prevention feasible: i) individuals at high risk of AD need to be identified before the earliest symptoms become evident, by which time extensive neurodege…
