Preliminary application of thermoluminescence and single aliquot regeneration method for dose reconstruction in soda lime glass
2013
The research described in this paper shows that the use of the single aliquot regeneration (SAR) method for thermoluminescence (TL) measurements applied to soda lime glasses allows to carry out a retrospective dose evaluation. We have followed a fast and efficient sample preparation procedure which permits measurements without powdering and sieving processes. We have analyzed the TL signal of commercial soda lime watch glass irradiated with 6 Mega Volts (MV) LINAC photons, 10 MeV LINAC electrons and 62 MeV protons. After the initial exposure and following TL reading, the samples are successively irradiated with increasing doses of photons. Therefore, for each sample its calibration curve is…
Elektroniskā uzraudzība Latvijā un ASV
2016
Latvijā, nosacītas pirmstermiņa atbrīvošanas no soda ietvaros, ir ieviesta elektroniskā uzraudzība. Tādēļ svarīgi pētīt, vai pašreizējais normatīvo aktu regulējums ļauj elektroniskai uzraudzībai savus mērķus izpildīt efektīvi. Bakalaura darba autors šajā darbā pētīja elektroniskās uzraudzības institūta izcelsmi, pašreizējo piemērojumu un iespējamo paplašināšanos Latvijā, balstoties uz Amerikas Savienoto Valstu pieredzi.
Characterization of Hardwood Soda-AQ Lignins Precipitated from Black Liquor through Selective Acidification
2016
In the development of integrated biorefinery process alternatives to produce value-added by-products, various black liquors from sulfur-free pulping processes offer potential feedstocks for recovering their main chemical constituents, lignin and aliphatic carboxylic acids. In this study, lignin fractions were obtained from silver birch (Betula pendula) soda-anthraquinone black liquor by carbonation (pH to about 8.5) or by acidification (pH to about 2) with H2SO4 after carbonation or directly. These fractions were characterized by Fourier transform infrared (FTIR), ultraviolet (UV), energy dispersive X-ray fluorescence (ED XRF), and 13C nuclear magnetic resonance (13C NMR) spectroscopy. In a…
Conflictual Rebordering: The Russia Policies of Finland and Estonia
2023
This article seeks to analyse the process of conflictual rebordering in the EU’s relations with Russia. The authors single out three major crises that triggered and shaped the process of toughening the border regime and the related transformations of political meaning of the EU-Russia border: the COVID-19 pandemic, the drastic deterioration of Moscow-Brussels relations in the beginning of 2021 and the war in Ukraine that started on 24 February 2022. Correspondingly, the EU’s reactions to each of these critical junctures might be described through the academic concepts of governmentality, normativity and geopolitics. Our aim is to look at the three ensuing models – governmental, normative an…
Quantum chemistry calculations on the effect of electron confinement upon the frontier molecular orbitals of ethylene and benzene in sodalite. Implic…
1997
Abstract Quantum chemistry calculations using HF / STO-3G, CEP-41G, and 3-21G basis sets have been carried out in order to study the effect of the electron confinement of ethylene and benzene in the microporous environment existing in a sodalite cage. The electron confinement produces an increase of 1.06 and 1.31 eV at the 3-21G level in the energy of the HOMO of ethylene and benzene, respectively, when placed in the centre of the cavity with respect to the HOMO energy in the gas phase. There is an increase in the energy of the HOMO when the molecules approach the walls of the zeolite.
British parliamentary attitudes towards a supranational parliament and the Consultative Assembly of the Council of Europe, 1948–49
2018
With a mounting communist threat from Eastern Europe after the Second World War, in Western Europe an attempt was made to create permanent structures not only to help in facilitating cooperation in different fields of life to rebuild societies, but to launch a common European supranational parliamentary body. The creation of the Council of Europe in May 1949 proved to be a compromise. It lacked a workable European parliament, as had been the vision of certain federalists in many Western European countries. During the creation process, the British foreign policy leadership emphasized the weak supranational parliamentarization of Western European politics. In this article, parliamentary debat…
Effect of sodium borohydride and hydrogen peroxide pretreatments on soda pulping of sugar maple (Acer saccharum)
2021
For recovering value-added wood-based organic material prior to delignification, sodium borohydride (NaBH4) and hydrogen peroxide (H2O2) pretreatments under alkaline conditions were performed before soda pulping of sugar maple (Acer saccharum) chips with sodium hydroxide (NaOH). In this investigation, it was determined whether the pulp yield could be increased by partly stabilizing the hemicelluloses by these pretreatments, and simultaneously obtains lower pulp kappa numbers. The results indicated that when aiming to the same kappa numbers (i.e., kappa numbers 14.3-20.5), roughly 3% higher pulp yield could be achieved if the chips were pretreated with alkaline 0.5% NaBH4 solutions, compared…
Metabolic Networks of Sodalis glossinidius: A Systems Biology Approach to Reductive Evolution
2012
BackgroundGenome reduction is a common evolutionary process affecting bacterial lineages that establish symbiotic or pathogenic associations with eukaryotic hosts. Such associations yield highly reduced genomes with greatly streamlined metabolic abilities shaped by the type of ecological association with the host. Sodalis glossinidius, the secondary endosymbiont of tsetse flies, represents one of the few complete genomes available of a bacterium at the initial stages of this process. In the present study, genome reduction is studied from a systems biology perspective through the reconstruction and functional analysis of genome-scale metabolic networks of S. glossinidius.ResultsThe functiona…
Syria from afar : how journalists in Finland and Germany cover the first YouTube war
2015
Miten uutisoida kaukaista sotaa, johon on vaikea ellei mahdoton päästä paikan päälle? Miten kertoa sodasta, jonka pääasialliset tietolähteet ovat sodan eri osapuolten media-aktivistit, hallitusta tukevat viestimet ja islamistitaistelijat, jotka kaikki rummuttavat omaa versiotaan tapahtumista? Ja ennen kaikkea: miten niiden esittämät väitteet, jotka usein vielä tulevat sosiaalisen median välityksellä, voi tarkistaa? Nämä ovat kysymyksiä, jotka ovat tämän tutkielman ytimessä ja myös sen lähtökohta. Syyrian sota on ulkomaantoimittajille valtava haaste. Olin itse 13 vuotta ulkomaantoimittajana Helsingin Sanomissa, ja painin usein sen kanssa, miten voin kertoa Syyrian tapahtumista mahdollisimman…
