Exploring the phenomenon of host confirmity pressure : immigrants' experiences of host conformity pressure in Finland in relation to their acculturat…
2012
The present study investigates the phenomenon of host conformity pressure and its possible consequences on acculturation from immigrants’ perspective. The research is motivated by the discrepancies between results of previous studies on the topic, the relatively small amount of research about immigration in Finland, and the will to examine adaptation issues from an intercultural communication perspective. The study uses different adaptation theories, notably Berry’s (1997) model of acculturative strategies. It also builds on Kim’s (2001) definition of host conformity pressure and Emerson’s (1968) theory of structural power. This research aims at examining (1) what immigrants identify as hos…
Biochemical and structural features of a novel cyclodextrinase from cow rumen metagenome.
2007
A novel enzyme, RA.04, belonging to the alpha-amylase family was obtained after expression of metagenomic DNA from rumen fluid (Ferrer et al.: Environ. Microbiol. 2005, 7, 1996-2010). The purified RA.04 has a tetrameric structure (280 kDa) and exhibited maximum activity (5000 U/mg protein) at 70 degrees C and was active within an unusually broad pH range from 5.5 to 9.0. It maintained 80% activity at pH 5.0 and 9.5 and 75 degrees C. The enzyme hydrolyzed alpha-D-(1,4) bonds 13-fold faster than alpha-D-(1,6) bonds to yield maltose and glucose as the main products, and it exhibited transglycosylation activity. Its preferred substrates, in the descending order, were maltooligosaccharides (C3-C…
"Vestirme de hombre y montar a caballo". Androginia y mujer moderna en la novela autobiográfica "Oculto sendero", de Elena Fortún
2021
espanolLa escritora Elena Fortun (Madrid, 1886-1952) es celebre por su mitico personaje de ficcion para ninos: la imaginativa y traviesa Celia. Este articulo pretende analizar la obra mas alternativa de la autora, Oculto sendero, publicada por primera vez en 2016 tras decadas escondida en una maleta: la autora no la quiso publicar en vida. Se trata de una obra de corte autobiografico donde Fortun usa el personaje de la pintora Maria Luisa Arroyo para hablar de su propio proceso de descubrimiento de una orientacion sexual que una madre autoritaria, el matrimonio y la presion social le impidieron vivir plenamente. Este articulo estudia el vinculo entre el concepto de «mujer moderna» y la adop…
Qualitative screening of 116 veterinary drugs in feed by liquid chromatography-high resolution mass spectrometry: potential application to quantitati…
2014
Abstract Veterinarian and human pharmaceuticals may be intentionally added to animal feed to enhance animal production. Monitoring these substances is necessary for protecting the consumers. In this work, a screening method covering 116 human and veterinary drugs has been developed and validated in five types of animal feed at 0.02 and 0.2 mg kg−1. After a simple extraction and dilution, the samples were analysed by ultra-high performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC-QTOF MS). Nearly all compounds tested were detected at 0.02 mg kg−1, based on the presence of the accurate-mass (de)protonated molecule. However, the identification using a…
Quantitative determination of casein genetic variants in goat milk: Application in Girgentana dairy goat breed
2016
The study was conducted to develop a high-performance liquid chromatographic (HPLC) method to quantify casein genetic variants (αs2-, β-, and κ-casein) in milk of homozygous individuals of Girgentana goat breed. For calibration experiments, pure genetic variants were extracted from individual milk samples of animals with known genotypes. The described HPLC approach was precise, accurate and highly suitable for quantification of goat casein genetic variants of homozygous individuals. The amount of each casein per allele was: αs2-casein A = 2.9 ± 0.8 g/L and F = 1.8 ± 0.4 g/L; β-casein C = 3.0 ± 0.8 g/L and C1 = 2.0 ± 0.7 g/L and κ-casein A = 1.6 ± 0.3 g/L and B = 1.1 ± 0.2 g/L. A good correl…

Pacientu ar ventrikulāro stomu aprūpe intensīvās terapijas un reanimācijas nodaļā
2018
Bakalaura darba tēma ir “Pacientu ar ventrikulāro stomu aprūpe intensīvās terapijas un reanimācijas nodaļā”. Smaga galvas smadzeņu trauma visbiežāk ir 15-35 gadu veciem cilvēkiem, un tā ir 1/3 ar traumatismu saistītu nāves gadījumu. Pieejamā medicīnas statistika liecina, ka gadā no katriem 100.000 iedzīvotājiem 150-200 tiek ievietoti stacionārā intensīvās terapijas nodaļā, galvas traumas dēļ. No hospitalizētiem pacientiem 8-11% ir galvas trauma ir ar 30-60% letalitāti. Smagas galvas traumas rada divējādus bojājumus – primārus un sekundārus, kas ir viens no nāves un invaliditātes cēloņiem pacientiem līdz 40 gadu vecumam, kā arī, galvenais, kvalitatīvas dzīves gadu zaudējuma iemesls. Tēmas ak…
The Metabolic Syndrome and Its Relationship to Hypertensive Target Organ Damage
2007
High blood pressure is often associated with various metabolic abnormalities, including abdominal obesity, dyslipidemia, elevated plasma glucose, and insulin resistance, which are the main features of the metabolic syndrome. The metabolic syndrome is extremely common worldwide. This high prevalence is of considerable concern because several studies suggest that the metabolic syndrome carries an increased risk for cardiovascular events. Several lines of evidence seem to indicate that the metabolic syndrome is associated with an increased prevalence of preclinical cardiovascular and renal changes, such as left ventricular hypertrophy, microalbuminuria, impaired aortic elasticity, and early ca…
Yodatos bajo condiciones extremas: Transiciones de fase inducidas por la presión, propiedades estructurales, vibracionales y electrónicas
2022
La estructura cristalina de los yodatos metálicos juega un papel importante en la respuesta SHG, así como también lo hacen la estructura de bandas electrónica y la energía de bandgap de la misma. Por ello, en esta tesis doctoral se estudia en profundidad y se presentan y analizan resultados de la estructura cristalina a alta presión, las vibraciones atómicas y la estructura de bandas electrónica de cuatro yodatos metálicos. Estos son el yodato de hierro, Fe(IO3)3, el yodato de cobalto, Co(IO3)2, el yodato de zinc, Zn(IO3)2, y yodato de magnesio Mg(IO3)2. Estos materiales han sido estudiados por medio de difracción de rayos X a alta presión (HPXRD), dispersión Raman a alta presión (HPRS), es…
Omega-3 Extraction from Anchovy Fillet Leftovers with Limonene: Chemical, Economic, and Technical Aspects
2019
International audience; We investigate selected chemical, technical, and economic aspects of the production of fish oil rich in polyunsaturated omega-3 fatty acids from anchovy filleting leftovers using d-limonene as the extraction solvent at ambient temperature and pressure. Entirely derived from the orange peel prior to orange squeezing for juice production, the bio-based solvent is easily recovered, affording a circular economy process with significant potential for practical applications.
