Flexible Perfluoropolyethers-Functionalized CNTs-Based UHMWPE Composites: A Study on Hydrogen Evolution, Conductivity and Thermal Stability
2022
Flexible conductive composites based on ultra-high molecular weight polyethylene (UHMWPE) filled with multi-walled carbon nanotubes (CNTs) modified by perfluoropolyethers (PFPEs) were produced. The bonding of PFPE chains, added in 1:1 and 2:1 weight ratios, on CNTs influences the dispersion of nanotubes in the UHMWPE matrix due to the non-polar nature of the polymer, facilitating the formation of nanofillers-rich conductive pathways and improving composites’ electrical conductivity (two to five orders of magnitude more) in comparison to UHMWPE-based nanocomposites obtained with pristine CNTs. Electrochemical atomic force microscopy (EC-AFM) was used to evaluate the morphological changes dur…
Flexible space-time process for seismic data
2009
Point processes are well studied objects in probability theory and a powerful tool in statistics for modelling and analyzing the distribution of real phenomena, such as the seismic one. Point processes can be specified mathematically in several ways, for instance, by considering the joint distributions of the counts of points in arbitrary sets or defining a complete intensity function. The conditional intensity function is a function of the point history and it is itself a stochastic process depending on the past up to time t. In this paper some techniques to estimate the intensity function of space-time point processes are developed, by following semi-parametric approaches and diagnostic m…
Elastīgais parametriskais modelis izdzīvošanas datiem ar konkurējošiem riskiem
2015
Konkurējošie riski ir izplatīta parādība izdzīvošanas analīzē. Tie rodas, kad subjekts atrodas vairāku savstarpēji izslēdzošu notikumu riska zonā. Populārākā metode, pētot šāda veida datus, ir Deivida Koksa semi-parametriskā modeļa izmantošana. Darbā ir aplūkots alternatīvais variants izdzīvošanas datiem ar konkurējošiem riskiem – elastīgais parametriskais modelis, kas sniedz gludus novērtējumus galvenajiem raksturlielumiem – konkrēto cēloņu riskam un kumulatīvo biežumu funkcijai. Turklāt, izmantojot šo modeli, ir viegli iekļaut no laika atkarīgus ietekmējošos mainīgos. Darbā tiek aprakstīta konkurējošo risku elastīgā parametriskā modeļa būtība, un metode ir salīdzināta ar Koksa modeli. Ir …
Tyytyväisyys työaikapankkiin
2009
Tutkimuksessa tarkasteltiin työaikapankkiin tyytyväisyyttä ennustavia tekijöitä. Tutkimus perustuu yhdeksässä työorganisaatiossa tehdyn kyselyn aineistoon (N = 268). Analyysit suoritettiin polkuanalyysina, jolloin selittäjien kausaalinen järjestys ja keskinäinen riippuvuus pystyttiin ottamaan huomioon. Selvä enemmistö vastaajista oli tyytyväisiä työaikapankkiin. Tyytyväisyyttä lisäsivät mahdollisuus kokonaisen vapaa-päivän viettämiseen säästetyistä tunneista, korkea asema organisaatiossa sekä työntekijöiden organisaation johdolta saama tuki. Tyytyväisyyttä heikensivät ongelmat säästettyjen vapaiden käytössä sekä työaikatilin saldorajojen huono mitoitus suhteessa työtehtävien vaativuuteen. K…
Family and work-related risk factors in children's social–emotional well-being and parent–educator cooperation in flexibly scheduled early childhood …
2023
Non-standard work schedules (NSWS) have become typical, but their associations with childcare arrangements and children's well-being are unknown. This study explores how risk factors are associated with the social–emotional well-being of girls and boys using flexibly scheduled early childhood education and care. Furthermore, the study investigates whether well-functioning cooperation between parents and educators buffers the negative effects of the risk factors. This study, which is a part of a larger survey carried out in three European countries, reports Finnish parents' (N = 146) perspectives. The results showed that high parental stress was associated with low child well-being. Strong p…
Impact of processing conditions on functionality of powders prepared from mixed protein system
2020
International audience; The projection of a global human population of around 9.5 billion by 2050 indicates that the demand for animal protein will double during this period. It seems therefore essential in regard to sustainability and food security to search for alternative protein sources that show nutritional and functional quality close to animal protein ones. In that respect, there is a growing interest in utilizing plant proteins as partial replacers of animal proteins in food. The reintroduction of plant proteins into our diet is a solution already envisaged by some vegetarian or flexitarian diets. In order to broaden this practice, one strategy is the use of protein mixes as an ingr…
O potędze "flexusa", czyli znaczenie przypadku w nowelach Guy de Maupassanta
2018
Guy de Maupassant, mistrz noweli realistycznej, szczególną rolę przypisuje w swych utworach przypadkowi, który uznaje za jeden z głównych czynników kształtujących ludzkie losy. W trzech analizowanych opowiadaniach: Włosy, Kelner, małe piwo!... oraz Clochetle, przypadek, który można określić łacińskim słowem lexus, oznaczającym ‘zwrot, punkt zwrotny’, urasta do rangi swoistego punktu ciężkości całej fabuły. We wszystkich trzech tekstach nagły zwrot akcji spowodowany przez błahe, banalne wydarzenie lub niespodziewany splot okoliczności wywiera silny wpływ na ułożoną i przewidywalną egzystencję bohaterów. A ponieważ w kwestii natury ludzkiej Maupassant jest pesymistą, stąd działanie owego flex…
Socially phobic clients' self-descriptions, treatment progress and reflexivity in short-term cognitive-constructivist group psychotherapy
2017
The aim of the research was to get information about different kinds of clients with social phobia and their therapeutic progress in cognitive-constructivist group psychotherapy. The aim was also to offer relevant information to clinicians working with socially phobic clients on how they could help the progress of the successful therapeutic change process of socially phobic clients, especially in early phases of the therapy when clients are developing a reflexive stance toward their own problematic experiences. Study I supported the view that negative self-image is central to social phobia, but this ranged from total piteousness to relatively few negative feelings of insufficiency. Three su…

Análisis del papel mediador de las capacidades de innovacion tecnológica en la relación entre la form’a organizativa flexible y el desempeño organiza…
2010
ResumenEste trabajo examina la relación entre la forma organizativa flexible y el desempeño organizativo tomando como variables mediadoras las capacidades para la innovación tecnológica, basándose para ello en los postulados del Enfoque Basado en Recursos. Esta cuestión de investigación es importante porque nos permite comprender mejor las variables antecedentes de la capacidad de innovación tecnológica relacionadas con el diseño organizativo y sus efectos en el desempeno organizativo. Para el contraste empírico se toma una muestra de 159 empresas industriales españolas y se modeliza un sistema de ecuaciones estructurales mediante la técnica Partial Least Squares (PLS). Los resultados muest…
