Darījumu inteliģences sistēma finanšu atskaitēm FINREP formātā
2017
Maģistra darbā ir izskatītas FINREP (Financial Reporting) finanšu datu atskaišu standarta pielāgošanas iespējas darījumu inteliģences sistēmām. FINREP standartu izstrādāja Eiropas Banku iestāde, to izmantošana ir reglamentēta Eiropas Savienības kredītiestādēm, kas atbilst noteiktām prasībām. Maģistra darba mērķis ir izpētīt FINREP finanšu atskaišu veidošanas iespējas Oracle Hyperion Financial Management maksas rīkā, kā arī izpētīt pieejamos atvērtā koda darījumu inteliģences risinājumus. Izvēloties vienu no atvērtā koda sistēmām, izpētīt to pielāgošanas iespējas FINREP atskaitēm, secinot vai ir iespējams panākt līdzīgo funkcionalitāti kā Oracle Hyperion rīkā.
Diversity Arrays Technology (DArT) for Pan-genomic Evolutionary Studies of Non-model Organisms
2007
BackgroundHigh-throughput tools for pan-genomic study, especially the DNA microarray platform, have sparked a remarkable increase in data production and enabled a shift in the scale at which biological investigation is possible. The use of microarrays to examine evolutionary relationships and processes, however, is predominantly restricted to model or near-model organisms.Methodology/principal findingsThis study explores the utility of Diversity Arrays Technology (DArT) in evolutionary studies of non-model organisms. DArT is a hybridization-based genotyping method that uses microarray technology to identify and type DNA polymorphism. Theoretically applicable to any organism (even one for wh…
Ilgtspējas ziņojuma nozīme un aktualitāte Baltijas valstu banku sektorā
2020
Ilgtspēja un korporatīvā sociālā atbildība ir tēmas, kam pastiprinātu nozīmi pievērš patērētāji, lēmumu pieņēmēji un uzņēmēji. Ilgtspējas ziņojums ir viens no galvenajiem rīkiem, kas palīdz, kā mērīt, salīdzināt un gūt ieskatu par organizācijas centieniem un sniegumu ilgtspējas jomā. Šī pētījuma mērķis bija analizēt ilgtspējas ziņošanas aktualitāti un tendences Baltijas valstu banku sektorā. Tika analizēts ziņojuma juridiskais statuss un ziņošanas tendences, veiktas intervijas ar ekspertiem un sektora pārstāvjiem un apkopoti un analizēti statistikas dati. Tika secināts, ka ilgtspējas ziņošana ir aktuāla un vienlīdz populāra visās Baltijas valstīs, ziņojumus iesniedzot apmēram pusei tirgus d…

Use of Ambient Ionization High-Resolution Mass Spectrometry for the Kinetic Analysis of Organic Surface Reactions
2016
In contrast to homogeneous systems, studying the kinetics of organic reactions on solid surfaces remains a difficult task due to the limited availability of appropriate analysis techniques that are general, high-throughput, and capable of offering quantitative, structural surface information. Here, we demonstrate how direct analysis in real time mass spectrometry (DART-MS) complies with above considerations and can be used for determining interfacial kinetic parameters. The presented approach is based on the use of a MS tag that - in principle - allows application to other reactions. To show the potential of DART-MS, we selected the widely applied strain-promoted alkyne-azide cycloaddition …
Kritisko detaļu pārbaudes optimizācija pielietojot kvalitātes standartus ienākošā materiāla kontroles laikā uzņēmumā SIA "Plockmatic Riga"
2022
Bakalaura darba tēma ir: “Kritisko detaļu pārbaudes optimizācija pielietojot kvalitātes standartus ienākošā materiāla kontroles laikā uzņēmumā “Plockmatic RIGA”. Kvalitātes standartu izmantošana ir process, kas nekad nezaudēs savu lomu ražošanas uzņēmumā, jo daudzu uzņēmumu galvenais mērķis ir sniegt kvalitatīvu produktu. Standartu izmantošanu var attiecināt ne tikai uz uzņēmumiem, bet tos arī var pielietot plašāk, piemēram, ISO standarti regulē vairāku uzņēmumu kopumu, attieksmi pret apkārtējo vidi. Darbs ir saistīts ar to, ka standartu ieviešana un izmantošana ir svarīgs process, konkrēti uzņēmumi savus izveidotos standartus var attiecināt uz piegādātājiem, lai jau ražošanas procesā nebūt…
Assessment of workflow feature selection on forest LAI prediction with sentinel-2A MSI, landsat 7 ETM+ and Landsat 8 OLI
2020
The European Space Agency (ESA)’s Sentinel-2A (S2A) mission is providing time series that allow the characterisation of dynamic vegetation, especially when combined with the National Aeronautics and Space Administration (NASA)/United States Geological Survey (USGS) Landsat 7 (L7) and Landsat 8 (L8) missions. Hybrid retrieval workflows combining non-parametric Machine Learning Regression Algorithms (MLRAs) and vegetation Radiative Transfer Models (RTMs) were proposed as fast and accurate methods to infer biophysical parameters such as Leaf Area Index (LAI) from these data streams. However, the exact design of optimal retrieval workflows is rarely discussed. In this study, the impact of…
Specific enrichment of 2-arachidonoyl-lysophosphatidylcholine in carotid atheroma plaque from type 2 diabetic patients
2016
IF 3.942; International audience; Background and aims: Diabetic patients are at high risk of stroke and coronary artery disease. Recent data suggest that arachidonic acid metabolism is altered in diabetic conditions and that these alterations contribute to accelerated atherosclerosis. Little is known about how these alterations affect the metabolism and the proportions of different lipid species within the atherosclerotic plaque. The aim of our study was to perform a targeted lipidomic analysis of human atherosclerotic lesions, with a specific focus on PUFA-containing lipid species, to reveal differences in the fatty-acid composition of plaque in diabetic patients compared with non-diabetic…
Potential Involvement of Osteopontin in Inflammatory and Fibrotic Processes in Pulmonary Embolism and Chronic Thromboembolic Pulmonary Hypertension
2019
Background Inflammation and incomplete thrombus resolution leading to obstructive fibrotic remodelling are considered critical mechanisms for the development of chronic thromboembolic pulmonary hypertension (CTEPH) after pulmonary embolism (PE). Osteopontin (OPN) is involved in a variety of biological processes including inflammation and tissue fibrosis. Methods OPN plasma concentrations were measured in 70 CTEPH and 119 PE patients. Tissue material from 6 CTEPH patients removed during pulmonary endarterectomy and murine venous thrombi induced by subtotal ligation of the inferior vena cava in C57BL/6 mice were analysed by (immuno)histochemistry. Results CTEPH patients had higher OPN plasma…
Carotid artery stenting with contralateral carotid occlusion in a rare aortic arch configuration
2010
We present the case of a 47-year-old man admitted to our department with an episode of aphasia. Duplex scan showed an occluded right internal carotid artery and severe left internal carotid artery stenosis. Contrast-enhanced computer tomography demonstrated a common trunk for both common carotid arteries anterior to the trachea and aberrant right subclavian artery posterior to the esophagus. The patient was considered to be a high risk for carotid endarterectomy and, consequently, we performed stenting of the left carotid artery. To our knowledge, this is the first case reporting the combination of these two aortic arch anomalies and the concomitant endovascular treatment of atherosclerotic…
