Alterazioni emoreologiche nella sindrome metabolica
2015
La sindrome metabolica (SM) si accompagna ad un elevato rischio cardiovascolare. Oltre ai tradizionali fattori di rischio, dei quali la SM rappresenta un’aggregazione, sono identificabili fattori non tradizionali quali l’assetto emoreologico. È noto da tempo che un disordine emoreologico si accompagna alla SM, ed è ipotizzabile una sua influenza sui meccanismi che instaurano e mantengono l’insulino-resistenza. In un gruppo di pazienti con SM abbiamo osservato un incremento della viscosità ematica e plasmatica e una riduzione della filtrabilità ematica. Il rapporto vita-fianchi, indice di obesità addominale, era direttamente correlato con la viscosità ematica e con l’ematocrito, mentre la vi…
On the mechanism of radiation synthesis of nanogels
2016
Radiation-engineered poly(N-vinyl pyrrolidone) nanogels are very interesting biocompatible nanocarriers for i.v. administration of therapeutics and contrast agents for bioimaging among other applications. Nanogels are usually produced upon irradiation of dilute aqueous polymer solutions. Under these conditions, the polymer radicals formed primarily react via intramolecular radical-radical combination forming intramolecular crosslinks. The manufacturing process is fast and effective and grants excellent control of particle size and simultaneous sterilization of the formed nanogels. Interestingly, primary amino groups and carboxyl groups, useful for (bio)conjugation, are also formed in a dose…
Coping with Uncertainty in an Agile Systems Development Course
2018
Uncertain and ambiguous environments are commonplace in information systems development (ISD) projects, and while different Agile frameworks welcome changes in organizational, technical, and business environments, the incurred uncertainty is known to negatively affect the development process and the quality of the final product. The effects of uncertainty on ISD projects have been studied in the past in real organizational contexts, but the effects of uncertainty on students in Agile systems development have received less attention from scholars. In this study, we measured the effects of experienced uncertainty on students’ performance in an Agile systems development course and how uncertai…
Hva ønsker ungdommene med kroppsøvingsfaget i fremtiden?
2019
Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2019 The background of the project:From 2020 a new curriculum in physical education will be used. Several studies have been carried out where the researchers have come to the conclusion that a majority of the students enjoyphysical education as it is. These results made mecurious,andas a result, in my study I have agoal of searching in-depth within what the adolescent want with physical education in the future. Issue:«What do the adolescent want with physicaleducation in the future?» Method:My study was conducted using a qualitativ method with a phenomenological approach, and I conducted both observation and interview. The selecti…

ADHD symptoms and maladaptive achievement strategies: the reciprocal prediction of academic performance beyond the transition to middle school
2023
This longitudinal study examined how two externalising behaviour problems, attention-deficit hyperactivity disorder (ADHD) and conduct disorder (CDs), are associated over time with low motivation (MAS), and how these problems effect academic performance. In our cross-lagged analysis, we found reciprocal effects between ADHD symptoms and MAS between Grades 5 and 6. Both domains also negatively predicted later academic performance. With CDs and MAS, no cross-lagged effects were found, although both were correlated and very stable over time, and negatively predicted later academic performance. These different kinds of externalising problem behaviours seem to differ in the way in which they int…
Silica powder obtained by sol-gel method as a support of organometallic vanadium catalyst for ethylene polymerization
2004
Sol-gel technique was employed to obtain the silica-type powder, which after modification procedure was applied as asupport of organometallic catalytic system for ethylene polymerization. The powder product was synthesized using hydrolysis and condensation of TEOS, catalyzed by ammonia. Obtained material and a reference support (commercial silica Davisil) were characterized to determine their particle size distributions, BET surface area, pore volume and diameter. Gas-phase adsorption of vanadium catalyst on analyzed support materials as well as adsorption from the solution in hexane were carried out. Both carrier materials were thermally pretreated prior catalytic systems syntheses and the…

Engelska – resurs eller hot mot svenska språket på finska högstadiet? : lärarnas synpunkter på engelskans roll i svenskundervisning
2016
Tämän tutkielman tarkoitus on selvittää ruotsinopettajien mielipiteitä englannin kielen vaikutuksesta ja asemasta yläkoulun ruotsinopetuksessa. Tutkielmassa keskitytään erityisesti siihen voiko ruotsinopettajien mielestä englantia hyödyntää myös ruotsin opettamisessa ja jos voi, niin miten. Lisäksi tutkielmassa selvitetään kokevatko ruotsinopettajat englannin resurssina vai uhkana ruotsin kielelle. Tutkielma on toteutettu kyselytutkimuksena keväällä 2015 ja siihen osallistui 30 ruotsinopettajaa. Sähköinen kyselylomake sisälsi yhdeksän kysymystä, jotka olivat sekä avoimia kysymyksiä että monivalintoja. Materiaali on analysoitu pääasiassa kvantitatiivisin menetelmin, sillä tulokset esitetään …
