Resolution of overlapped non-absorbing and absorbing solutes using either an absorption null-balance detection window or multivariate deconvolution a…
2004
Abstract Non-absorbing alkyl ether sulfates (AES) can be separated using anthraquinone-2-carboxylic acid (AQCA) as a probe; however, absorbing alkyl benzene sulfonates (ABS), if present, interfere indirect detection of most AES oligomers. Overcoming of this interference, as well as the simultaneous characterisation and evaluation of AES, fatty acids and ABS, was accomplished by using a diode-array detector and the procedures here discussed. First, it was shown that ABS can be made undetectable by using a 9 nm wide and 227 nm centred charge-absorptivity null-balance detection window (NBDW), where its contribution to the absorbance cancels the dilution effects that its presence induces on the…
Separation and determination of homologues of linear alkylbenzenesulfonates by nonaqueous capillary zone electrophoresis using alkylammonium salts in…
2001
The separation of linear alkylbenzene sulfonates (LAS) by nonaqueous capillary electrophoresis (NACE) using negative polarity, and a buffer containing acetic acid and an alkylamine in nonaqueous ethanol, has been investigated. Several primary, secondary, and tertiary alkylamines with alkyl chains of different length were compared. The solutes travelled against the electroosmotic flow (EOF), and at the same time were braked by association with the alkylamine molecules or with the alkylammonium ions. The best resolution between adjacent LAS homologues (R approximately 2.1), partial isomer resolution in two peaks, and at the same time an excellent repeatability, was obtained with a small dipen…
Development cooperation projects - on the road towards social organisational capital : case study: Latvia
2010
DEVELOPMENT COOPERATION PROJECTS – ON THE ROAD TOWARDS SOCIAL ORGANISATIONAL CAPITAL CASE STUDY: LATVIA Sintija Dutka Master’s Thesis Social and Public Policy / Master’s programme in Development and International Cooperation Department of Social Sciences and Philosophy University of Jyväskylä Instructor: Marja Järvelä English proof reader: Mark Dennis Time period: Autumn 2009 / Spring 2010 Pages: 97 pages + annex 4 pages The purpose of the thesis is to examine ways in which implementation of a development cooperation project influences the capacity of project implementing organisations in Latvia. Furthermore, the study aims to discover whether social capital generated during the project cyc…

Diffuse Liver Diseases: Role of imaging
2018
Nowadays, the most common imaging techniques allow to study focal liver lesions with high diagnostic accuracy but a relatively recent emerging field of interest is represented by diffuse liver disease. They include a variegated series of storage and metabolic pathologies (ie, iron overload disorders and steatosis) requiring a precise diagnosis not always possible at imaging due to the overlapping of findings at conventional ultrasound, CT, or MR studies. In recent years, several imaging tecniques and specific softwares have been developed, especially for ultrasound and MR imaging, in order to identify different parameters useful in the noninvasive recognition and follow-up of these diffuse …
Clinical indications for the use of cardiac MRI. By the SIRM Study Group on Cardiac Imaging
2013
Cardiac magnetic resonance (CMR) is considered an useful method in the evaluation of many cardiac disorders. Based on our experience and available literature, we wrote a document as a guiding tool in the clinical use of CMR. Synthetically we describe different cardiac disorders and express for each one a classification, I to IV, depending on the significance of diagnostic information expected.

Dienas kārtības plānošanas lietotne
2018
Kvalifikācijas darba ietvaros tika izstrādāta lietotne ar dienas plānošanas kārtības tematiku. Darba autors ir Latvijas Universitātes students Antons Jelčins. Kvalifikācijas darba sistēma ir plānošanas kārtības lietotne, kurā lietotāji var ērti plānot pasākumus. Lietotne ļauj lietotājiem efektīvāk organizēt savu laiku, saglābāt nepieciešamo informāciju, atzīmēt svarīgus plānotus datumus un pievienot tos arī dienas gaitā. Kvalifikācijas darba automatizētajā sistēmā galvenais uzsvars tiek likts uz lietotāja dienas kārtošanas informācijas veidošanu, tāpēc sistēmas prioritāte ir reģistrēts lietotājs, kuram ir ievērojams iespēju pārākums pār nereģistrēto lietotāju, tādejādi motivējot lietotāju r…
Evaluation of 2,3-epoxypropyl groups and functionalization yield in glycidyl methacrylate monoliths using gas chromatography
2014
Abstract Poly(glycidyl methacrylate- co -ethylene dimethacrylate) (poly(GMA- co -EDMA)) is most frequently used as parent monolith to obtain stationary phases with a variety of surface chemistries for liquid chromatography and capillary electrochromatography. Functionalization is performed by opening the accessible 2,3-epoxypropyl groups of the monolith with a suitable reagent. The number of 2,3-epoxypropyl groups which are accessible before and after the functionalization reaction, and the grafting yield, are important parameters, required both to optimize functionalization and to interpret the chromatographic performance of functionalized monoliths. In this work, a method capable of provi…
