Sveriges irredenta : försvenskningen av de finskspråkiga i Norrbotten 1888-1921 ur identitetsbyggandets synvinkel
2009
In this study the task is to point out the key features in the making of a Swedish nation from the perspective of a minority language, i.e. the Finnish speaking minority in the region of Norrbotten, Sweden. Swedish historians usually list the fear of Russia (Russia, the arch-enemy -topos) and the Laestadian movement as main reasons for the policy of cultural assimilation of the Finnish-speaking minority. In this study the main task is to use the post modern discourse analysis (especially Michael Shapiro) in reading texts between the years 1888 and 1921. For this purpose I have gone through material of the period, i.e. debates in the Swedish Parliament, the newspaper Haparandabladet, pamflet…

Väliesimiehen johtamiskompetenssi ja niiden kehittäminen : myymäläpäälliköiden kokemuksia
2015
Tämän tutkimuksen tarkoituksena oli selvittää väliesimiestason myymäläpäälliköiden kokemuksia käyttämistään johtamiskompetensseista, sekä kuvata työssä kohdattuja haastetilanteita, joissa näitä kompetensseja hyödynnetään. Lisäksi tutkimuksessa pyrittiin selvittämään myymäläpäälliköiden kokemuksia siitä, miten organisaation sisäinen esimieskoulutus kehitti näitä johtamisen kompetensseja. Tutkimusta esimiesten kompetensseista on paljon, mutta kaupanalan esimiesten osaamiseen ja sen kehittämiseen ei olla aiemmin keskitytty ja näin tutkimus eroaa kontekstillaan aiemmista esimiestason kompetenssitutkimuksista. Kohdeorganisaation myymäläpäälliköille tutkimus antoi mahdollisuuden reflektoida ja tu…
Tailoring the interaction between a gold nanocluster and a fluorescent dye by cluster size : creating a toolbox of range-adjustable pH sensors
2022
We present a novel strategy for tailoring the fluorescent azadioxatriangulenium (KU) dye-based pH sensor to the target pH range by regulating the pKa value of the gold nanoclusters. Based on the correlation between the pKa and surface curvature of ligand-protected nanoparticles, the pKa value of the gold nanoclusters was controlled by size. In particular, three different-sized para-mercaptobenzoic acid (p-MBA) protected gold nanoclusters, Au25(p-MBA)18, Au102(p-MBA)44, and Au210–230(p-MBA)70–80 were used as the regulator for the pH range of the KU response. The negatively charged gold nanoclusters enabled the positively charged KU to bind to the surface, forming a complex and quenching the …
Latvijas 20.gs. vēstures interpretāciju maiņa latviešu prozā (1986-1991)
2016
Maģistra darba tēma ir “Latvijas 20. gadsimta vēstures interpretāciju maiņa latviešu prozā (1986 – 1991)”. Šajā laika posmā sākas vēstures pārvērtēšana prozā un vēstures zinātnē, atteikšanās no padomju interpretācijām, parādās arvien drosmīgākas publikācijas ar nesenās vēstures vērtējumiem. Maģistra darba mērķis ir noskaidrot, kā mainās vēstures interpretācijas latviešu prozā konkrētā laika periodā (1987 – 1991). Galvenie maģistra darba uzdevumi ir izpētīt vēstures interpretāciju maiņas procesu, analizējot izdotos prozas darbus un to tematiku, un salīdzināt vēstures interpretāciju maiņu prozā un vēstures zinātnē šajā laika periodā. Maģistra darbā analizētas trīs prozā akcentētās Latvijas 20…

Mechanisms of irreversible aquaporin-10 inhibition by organogold compounds studied by combined biophysical methods and atomistic simulations
2021
Abstract The inhibition of glycerol permeation via human aquaporin-10 (hAQP10) by organometallic gold complexes has been studied by stopped-flow fluorescence spectroscopy, and its mechanism has been described using molecular modelling and atomistic simulations. The most effective hAQP10 inhibitors are cyclometalated Au(III) C^N compounds known to efficiently react with cysteine residues leading to the formation of irreversible C–S bonds. Functional assays also demonstrate the irreversibility of the binding to hAQP10 by the organometallic complexes. The obtained computational results by metadynamics show that the local arylation of Cys209 in hAQP10 by one of the gold inhibitors is mapped int…
Relaxation of a weakly discontinuous functional depending on one control function
2008
The paper considers an optimal control problem of the typewhere the set M of admissible controls consists of all measurable vector‐functions h, which can take only two values h1 or h2. It is shown that the relaxation of this problem can be explicitly computed by rank‐one laminates.
Practice for determining friction in hydraulic winch systems
2020
This paper presents a method for estimating friction in hydraulic active heave compensated (AHC) offshore winches. The method is a two-step approach where the first step is to model the friction loss in the hydraulic motors based on data from the sub-supplier. The second step requires real-life testing, where the remaining friction losses in the winch system is identified and modeled. In this context, a practice is characterized by obtaining a friction loss estimation with the highest possible accuracy over the widest possible range of operating conditions with a limited amount of experimental work. The method benefits from the use of parametric models, sub-supplier data, and real-life meas…
Fractional calculus approach for the representation of power spectral densities and correlation functions in wind engineering
2010
The paper deals with the digital simulation of wind velocity samples by Fractional Spectral Moment function. It is shown that such a function represents a third useful way to characterize a stationary Gaussian stochastic process, alongside the power spectral density and the correlation function. The method is applied to wind velocity fields whose power spectra is given by the Kaimal’s, the Davenport’s and the Solari’s representation. It is shown that by constructing a digital filter whose coefficients are the fractional spectral moments, it is possible to simulate samples of the target process as superposition of Riesz fractional derivatives of Gaussian white noise processes.
