Vokālais burdons latviešu tradicionālās mūzikas interpretācijās 21.gadsimta amatierierakstos
2018
Folkloras pētnieku un mākslinieku vidū vēl joprojām izskan atšķirīgi viedokļi par to, vai tradicionālās kultūras materiālos balstīta muzikāla jaunrade ir vēlama un kādiem būtu jābūt tās priekšnosacījumiem. Ir daudz spēcīgu argumentu, kādēļ tradīcija jāsaglabā neskarta, kamēr par populāru tendenci kļūst tradicionālās kultūras elementu izmantošana laikmetīgā daiļradē. Par darba apskates objektu izvēlēta Latvijas reģionam raksturīgas tradicionālas vokālās daudzbalsības - burdona - izmantošana dažādos mūsdienu mūzikas amatierierakstos, kas analizēti, un mērķis ir analizēt apskatītās mūzikas autoru motivāciju laikmetīgā mūzikā izmantot šo arhaisku tradīciju, kā arī raksturot attiecīgās kultūrkop…

Husserl's Transcendentalization of Mathematical Naturalism
2020
Abstract The paper aims to capture a form of naturalism that can be found “built-in” in phenomenology, namely the idea to take science or mathematics on its own, without postulating extraneous normative “molds” on it. The paper offers a detailed comparison of Penelope Maddy’s naturalism about mathematics and Husserl’s approach to mathematics in Formal and Transcendental Logic (1929). It argues that Maddy’s naturalized methodology is similar to the approach in the first part of the book. However, in the second part Husserl enters into a transcendental clarification of the evidences and presuppositions of the mathematicians’ work, thus “transcendentalizing” his otherwise naturalist approach t…
Traumatismos dentarios en Valencia
2015
La Traumatología dental es la rama de la Odontología que aborda la epidemiología, etiología, prevención, evaluación, diagnóstico y tratamiento de los traumatismos producidos sobre los dientes, maxilares y tejidos circundantes. También abarca las secuelas postraumáticas, como la reabsorción radicular y su tratamiento. Hoy en día las lesiones traumáticas son la segunda causa de atención odontológica después de la caries, habiéndose producido un aumento en la prevalencia de estas lesiones en las últimas décadas. En todo el mundo existen más de 3.000 millones de pacientes con traumatismos dentales y cada año se añaden aproximadamente 60 millones más, demostrándose la alta prevalencia de estas l…
Denying the Truth Does Not Change the Facts: A Systematic Analysis of Pseudoscientific Denial of Complex Regional Pain Syndrome
2021
Purpose Several articles have claimed that complex regional pain syndrome (CRPS) does not exist. Although a minority view, it is important to understand the arguments presented in these articles. We conducted a systematic literature search to evaluate the methodological quality of articles that claim CRPS does not exist. We then examined and refuted the arguments supporting this claim using up-to-date scientific literature on CRPS. Methods A systematic search was conducted in MEDLINE, EMBASE and Cochrane CENTRAL databases. Inclusion criteria for articles were (a) a claim made that CRPS does not exist or that CRPS is not a distinct diagnostic entity and (b) support of these claims with subse…
Shell morphology of the unionid mussels (Anodonta anatina, Unio pictorum and U. tumidus) in relation to gender and trematode parasitism
2015
Freshwater mussels (Unionoida) show great variability in shell morphology which can be associated with differences in habitat, sex and/or parasite infection. Three unionid mussel species, (Anodonta anatina, Unio pictorum and Unio tumidus) were collected from two sites Lake Saravesi, (Laukaa) and Lake Kuivasjarvi, (Oulu), between May - October 2012. Intraspecific trends that were associated with the mussels’ sex and/or parasites infection were studied and observations were made on how sex and parasite infection could have a role in shells morphological characters/patterns. The study revealed a range of morphometric differences among and across populations, as well as, within and between spec…
Dioxomolybdenum(VI) and -Tungsten(VI) Amino Bisphenolates as Epoxidation Catalysts
2016
Low-cost metallate salts Na2MO4·2H2O (M = molybdenum, tungsten) react with a tridentate amine bisphenol bis(2-hydroxy-3-tert-butyl-5-methylbenzyl)methylamine (H2ONOtBu) under ambient conditions in acidic methanol solutions. The reactions lead to the formation of isostructural dioxo complexes [MO2(ONOtBu)(MeOH)]·MeOH in convenient yields. Spectral data as well as X-ray analyses reveal these complexes to be isostructural. Both compounds were tested as catalysts for epoxidation of olefins using cis-cyclooctene, cyclohexene, norbornene and styrene as substrates and tert-butyl hydroperoxide and hydrogen peroxide as oxidants. The molybdenum complex catalyses selectively the oxidation of cis-cyclo…

Cleavage of Ge–Ge and Sn–Sn Triple Bonds in Heavy Group 14 Element Alkyne Analogues (EAriPr4)2 (E = Ge, Sn; AriPr4 = C6H3-2,6(C6H3-2,6-iPr2)2) by Rea…
2016
The reactions of heavier group 14 element alkyne analogues (EAriPr4)2 (E = Ge, Sn; AriPr4 = C6H3-2,6-(C6H3-2,6-iPr2)2) with the group 6 transition-metal carbonyls M(CO)6 (M = Cr, Mo, W) under UV irradiation resulted in the cleavage of the E–E triple bond and the formation of the complexes {AriPr4EM(CO)4}2 (1–6), which were characterized by single crystal X-ray diffraction as well as by IR and multinuclear NMR spectroscopy. Single-crystal X-ray structural analyses of 1–6 showed that the complexes have a nearly planar rhomboid M2E2 core with three-coordinate group 14 atoms. The coordination geometry at the group 6 metals is distorted octahedral formed by four carbonyl groups as well as two br…
