Pupils Creative Activity in Textile Art at Competition
2014
The open olympiads of home economics and technologies encourage pupils of grades 5-9 to be creative in applying textile techniques. They also popularize textile art. Purpose of the study is to analyse the results of pupils’ creative work during the 10th open olympiad of home economics and technologies. Method: analysis of textile works. 376 pupils’ works from the 1st round and 85 works of the 2nd round have been analysed and assessed according to the following criteria: compliance with the task, unity of composition, composition of colours, compatibility of materials, originality, quality of the technical accomplishment, functionality. In the olympiad traditional Latvian handicraft techniqu…
Latvijos ginkluotųjų pajėgų partizanų daliniai 1919 metais | From Guerrillas to Soldiers: The Activities of Guerrilla Units of the Latvian Army in 19…
2014
On the basis of documents in the Latvian State Archives, this paper discusses the armed struggleagainst the Soviet authorities in Vidzeme, in northern Latgala, and Sela, which took placeduring the Latvian Wars of Independence, and was joined voluntarily by the local populationin an organised way. The discussion tells about the armed guerrilla groups that operated inVidzeme and northern Latgala in 1919, and formed a serious obstacle to the establishmentof Soviet power, the participation of ethnic minorities in guerrilla groups, and the features ofthe guerrilla fighting. The collaboration between Latvian guerrillas and Lithuanian troops, andtheir role in the expulsion of Soviet Latvian troops…
MODERN DIDACTIC TERMS IN THE CONTENT OF LATVIAN LANGUAGE AND LITERATURE STUDIES
2015
The article is devoted to a pending matter in the Latvian linguistics and methodology of language and literature – the formation of the system of terminology. The 90-ies of the 20th century when Latvia gained its national independence brought changes not only in the political and economic life but also in the terminology because new realities, which appeared in life, needed new names. Essential transformation in education brought along changes in the nomination system of the specific realities in the sphere. By establishing broader contacts with the pedagogical information field of the Western countries, translating scientific articles one comes in touch with specific concepts of the sphere…
Implementing a Face Recognition System for Media Companies
2018
During the past few years face recognition technologies have greatly benefited from the huge progress in machine learning and now have achieved precision rates that are even comparable with humans. This allows us to apply face recognition technologies more effectively for a number of practical problems in various businesses like media monitoring, security, advertising, entertainment that we previously were not able to do due to low precision rates of existing face recognition technologies. In this paper we discuss how to build a face recognition system for media companies and share our experience gained from implementing one for Latvian national news agency LETA. Our contribution is: which …
Public Financing Support Options to Micro-Enterprises for Innovation
2020
Innovation related to the technological advances of entrepreneurship are essential in Industry 4.0. The availability of sufficient funding is one of the factors promoting innovations in companies. Therefore the issue of access to finance remains relevant. The study investigates the availability of public financial support for micro-enterprises - the largest enterprise category in Latvia (approximately 94%), focusing on those for whom the introduction of innovations is essential for their growth. In an ad hoc survey of companies registered in Latvia in nationally defined sectors, entrepreneurs disclosed their sources of funding over the three-year period: 2015-2017. Valid responses from 2511…
The occurrence of Dechlorane Plus and related norbornene-based flame retardants in Baltic wild salmon (Salmo salar)
2015
Twenty five Baltic wild salmon (Salmo salar) specimens were analysed for the content of Dechlorane-related compounds (DRCs). Out of the ten analysed DRCs, seven compounds were detected in the muscle tissues of salmon, including Dechlorane (Dec) 602, Dec 603, syn- and anti-stereoisomers of Dechlorane Plus (DP), Dechlorane Plus monoadduct (1,3-DPMA), hexachlorocyclopentadienyl-dibromocyclooctane (DBHCTD), and Mirex. The concentrations of Dec 604 and two DP dechlorinated compounds - decachloropentacyclooctadecadiene (Cl10DP) and undecachloropentacyclooctadecadiene (Cl11DP) - were below the limit of detection in all samples. The aggregated concentrations of DRCs (ΣDRC) were in the range of 551-…
Occurrence of polybrominated diphenyl ethers, perfluorinated compounds, and nonsteroidal anti-inflammatory drugs in freshwater mussels from Latvia.
2018
Abstract The occurrence of polybrominated diphenyl ethers (PBDE), perfluorinated compounds (PFC), and nonsteroidal anti-inflammatory drugs (NSAID) in Latvian freshwater ecosystems was evaluated by using filter-feeding mussels as bioindicators. Twenty four samples of mussels were collected from freshwater bodies throughout the territory of Latvia during the summer of 2017. PBDE contamination was ubiquitous, reaching the highest total concentration of 193.2 pg g−1 w.w. BDE-209 was the most abundant compound, followed by penta-BDE components BDE-49, -100, −99, −153, −154, and −47 in decreasing order. The levels of PFCs in Latvian mussels were generally lower than those reported from other regi…
Determination of pharmaceutical residues and assessment of their removal efficiency at the Daugavgriva municipal wastewater treatment plant in Riga, …
2017
Pharmaceutical products (PPs) belong to emerging contaminants that may accumulate along with other chemical pollutants in wastewaters (WWs) entering industrial and/or urban wastewater treatment plants (WWTPs). In the present study, the technique of ultra-high-performance liquid chromatography coupled to Orbitrap high-resolution mass spectrometry (Orbitrap-HRMS) was applied for the analysis of 24 multi-class PPs in WW samples collected at different technological stages of Daugavgriva WWTP located in Riga, Latvia. Caffeine and acetaminophen levels in the range of 7,570–11,403 ng/L and 810–1,883 ng/L, respectively, were the predominant compounds among 19 PPs determined in the WW. The results i…
Polychlorinated biphenyls and some pesticides in perch (Perca Fluviatilis) from inland waters of Latvia
1999
Polychlorinated biphenyls (PCBs), DDT - related substances, hexachlorocyclohexane (HCH) isomers and hexachlorobenzene (HCB) were analysed in perch (Perca fluviatilis) from Latvian lakes and rivers. DDE is present in the highest concentrations in all samples; 62–170 ng/g lipid weight in perch from rural areas and 460 ng/g in perch from the Riga area. Individual dominating PCB congeners were in the range 16–45 ng/g and 200–210 ng/g, respectively. The degree of contamination of rural areas in Latvia of these organohalogen substances is in the same range as in background areas in Sweden. Riga, the major urban area in Latvia, is shown to be more polluted with PCBs than other areas in Latvia.
