ES budžeta un finanšu instrumentu ietekme uz startup uzņēmumiem Baltijas valstīs
2021
Autores maģistra darba tēma ir “ES budžeta un finanšu instrumentu ietekme uz startup uzņēmumiem Baltijas valstīs”. Efektīva ES budžeta un finanšu instrumentu izmantošana ietekmē valsts attīstības ātrumu un spēju iekarot starptautisko tirgu. Baltijas valstu kontekstā ES budžeta un finanšu līdzekļu izmantošanai startup uzņēmumu attīstībai ir izšķiroša loma startup ekosistēmu izveidē, produktivitātes uzlabošanā un jaunu darba vietu radīšanā. Tomēr šobrīd ES budžeta un finanšu līdzekļu izmantošanu startup uzņēmumu attīstībai nevar uzskatīt par pietiekami efektīvu un ilgtspējīgu. Pētījums ir balstīts uz ES un Baltijas valstu plānošanas dokumentu analīzi, kā arī Baltijas valstu startup ekosistēmu…
A theoretical study of the electronic spectrum of cis-stilbene
1999
Abstract The valence and Rydberg electronic excited singlet states of cis -stilbene have been studied using multiconfigurational second-order perturbation theory (CASPT2). The study includes a geometry determination of the ground state. The geometry of the lowest 1 B state has also been optimized, leading to a structure where the two benzyl groups are nearly perpendicular. The calculated vertical spectrum is in agreement with the occurrence of three main bands in the observed one-photon absorption spectrum. Below the relatively intense transition to the 2 1 B (HOMO→LUMO) state at 4.61 eV, two weak transitions have been computed at 4.11–4.45 eV, which correspond to transitions to the 1 1 B a…
Valence states of copper in copper ferrite spinels CuxFe3−xO4 (0 < x ≤ 1) fine powders: Evidence of copper insertion
1997
Abstract The oxidation in cation deficient spinels of copper iron spinels Cu x Fe 3− x O 4 (0 x ≤ 1) synthesized by soft chemistry with a grain size x per mole of ferrite, three oxidation phenomena corresponding to Cu + at B-sites (130°C), Fe 2+ at B-sites (180°C) and Cu + at A-sites (240°C) have been found in close relation with the cation-oxygen distance of each oxidizable cation. For nonstoichiometric synthesized spinels Cu x Fe 3− x O 4+ δ with δ x , the presence of additional interstitial Cu + ions has been envisaged. The oxidation temperature of these interstitial ions (> 300°C) is higher than that for Cu + ions at Asites suggesting that interstitial copper ions also essentially resid…
Heart rate responses during the modified six-minute walk test among Special Olympics athletes
2021
Objective: The construct validity of the modified six-minute walk test (m6MWT) was examined by addressing the following questions: 1) do participants attain a steady state plateau in heart rate (HR) within the range of 110-150 beats per minute? 2) at what percentage of their predicted HR maximum were participants during each minute of the test? Material and Methods: Participants were 36 (male=56%) Special Olympics athletes aged 34.4 years (SD = 12.7). Following familiarization, participants completed the m6MWT while wearing a Polar Team 2 heart rate monitor. Results: By the end of the first minute, average heart rate was 120bpm, and a factorial repeated measures ANOVA revealed that steady s…
Šamisena un tā mūzikas inovācijas pēc 2. pasaules kara
2015
Maģistra darbs „Šamisena un tā mūzikas inovācijas pēc 2. pasaules kara” ir veltīts japāņu tradicionālā instrumenta šamisena un tā mūzikas padziļinātai izpētei pēc Otrā pasaules kara. Konkrēti tiek pētītas laika gaitā radītās instrumenta mūzikas un spēles stila inovācijas, kā arī ko šīs izmaiņas nozīmē mūsdienu mūzikas kontekstā. Tēmas aktualitāte tiek balstīta uz to, ka pēdējo divdesmit gadu laikā šamisena pielietojums japāņu sabiedrībā ir pastiprinājies, kā arī plaši izplatījies ārpus Japānas. Šis instruments ir ieguvis popularitāti ne tikai vecāko paaudžu vidū, bet arī jauniešu starpā, un tiek lietots daudzu moderno mūzikas stilu izpildīšanai. Darba mērķis bija izpētīt izmaiņas, ar kurām …
Sense-Making, Meaningfulness, and Instrumental Music Education
2020
The purpose of this paper is to re-examine the nature of "meaning" and "meaningfulness" in the context of instrumental music education. By doing so, I propose to expand the ways in which instrumental music educators conceive their mission and the ways in which we may instill meaning in people's lives. Traditionally, pursuits of philosophical deliberation have claimed that meaningfulness comes from either personal happiness (e.g., Jeremy Bentham and John Stuart Mill) or an impersonal sense of duty (e.g., St. Augustine, St. Thomas Aquinas, and Immanuel Kant). However, philosopher Wolf (2010) criticizes these positions in favor of a broader perspective, one that arises from understanding that …
409 Using rai-hc assessment instrument to classify home care clients in Finland based on fire emergency evacuation capacity
2016
Background When an uncontrollable fire is detected in a building there may be a 2–3 minutes window for the occupants to move to safety. Poor physical function and cognition may become critical factors in an evacuation situation. In this study a novel functional scale measuring emergency evacuation capacity of home care clients is presented. Methods A fire security expert visited about 250 home care clients assessing their evacuation capacities. For the evacuation capacity three categories were used: 1) is able to evacuate; 2) may be able; 3) unable to evacuate. This data was linked to comprehensive assessments of clients functional and health status performed by home care nurses using the i…
Gas chromatography-mass spectrometry characterization of the varnish and glue of an ancient 18th century double bass.
2007
A GC–MS investigation is conducted on the double bass “Panormus”, property of Conservatorio di Musica “Vincenzo Bellini” in Palermo. The most important components of the varnish (fatty acids) and of the glue (proteinaceous amino acids), with which the musical instrument was treated in the past, are determined. The analyses are carried out by prior derivatization of fatty acids by acidic methanol and of amino acids by acidic methanol and trifluoroacetic anhydride (TFAA). Analytes identification is achieved by direct comparison with several reference materials and the use of a digitized library.
Octupolar excitation of ion motion in a Penning trap: A theoretical study
2014
Abstract High-precision Penning-trap mass spectrometry uses the resonant conversion of the magnetron motional mode into the cyclotron motional mode to determine the cyclotron frequency of the ions under investigation. Usually the conversion process is performed by interaction of the ions with external quadrupolar rf-fields. Recently it was found that conversion by means of octupolar rf-fields entails a tremendous increase in mass resolution and is thus of great interest. However, the conversion results depend in an intricate way on the amplitudes and phases of the octupolar rf-field and of the motional modes of the ions. Experimental progress was hampered by the lack of an underlying theory…
