Šī bakalaura darba pētījuma objekti ir ‘Korvina cikla’ pirmie divi romāni - ‘Deviņi Amberas prinči’ un ‘Avalonas ieroči’. Darba mērķis ir izpētīt alūziju funkcijas iepriekš minētajos darbos, lai sasniegtu izvirzīto mērķi tika pielietota kvalitatīvā kontentanalīze (jeb satur analīze). Alūziju funkcijas kuras tika sīkāk pētītas bija tās kuras ataino tēlu vai tēlus, tās kuras ataino vidi, tās kuras ataino atmosfēru, un tās kurās izraisa humoru. Pēc darba veikšanas tika secināts, ka funkcijas tika real…

Diastereoselective Synthesis of 2-Phenylselenenyl-1,3-anti-Diols and 2-Phenylselenenyl-1,3-anti-Azido-Alcohols via Hydroxy- and Azido-Selenenylation …

2005

A method to synthesize 2-phenylselenenyl-1,3-anti-diols and 2-phenyl- selenenyl-1,3-anti-azidoalcohols via hydroxy- or azido-selenenylation of trans-allylic alcohols is reported. Moreover, the first example of hydroxyl-selenenylation of an allylic azide is presented. Yields ranging from moderate to good and diastereomeric ratios up to 95:5 are achieved.

Pyroxene-based glass-ceramics as glazes for floor tiles

2005

Abstract Crystallization of a glass with composition in the diopside primary crystallization field in the MgO–CaO–Al 2 O 3 –SiO 2 quaternary system was investigated. Also the action of some additives, nucleants and fluxes, in the pyroxene development was examined. Glasses were prepared by conventional melting of a mixture of raw materials and cooled by pouring in water. Pellets of glass powder specimens were thermally treated at several temperatures up to 1200 °C. The crystallization path was followed by X-ray diffraction powder (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDX). The results proved that, in addition to the effect of B 2 O 3 and TiO 2 in…

Una iniciativa artística de los alumnos de la Escuela de Bellas Artes de San Carlos: la exposición organizada en el vestíbulo del teatro Principal de…

2004

En julio de 1882, los alumnos de la Escuela de Bellas Artes de San Carlos de Valencia organizaron una exposición artística en el vestíbulo del teatro Principal, con el objeto de destinar sus beneficios a la creación de otra de carácter permanente. Aunque la muestra fue muy visitada y resultó un éxito, el proyecto de exposición permanente, no obstante, todavía tendría que esperar algunos años para llegar a ser una realidad. (A)

Estudio de los factores ambientales que afectan a la conducta de actividad física en niños y niñas en edad preescolar

2017

Introducción: La actividad física es una conducta de salud que conlleva múltiples beneficios para la población. En niños y niñas de preescolar, la realización de actividad física conlleva una mejora de la adiposidad corporal, salud ósea, desarrollo de habilidades motoras, salud psicosocial, desarrollo cognitivo y aspectos de la salud cardiometabólica. La realización de dicha actividad va a depender de varios factores, entre los que se encuentran factores ambientales, así como el tiempo en el que pasan los niños y niñas en el contexto escolar. Objetivo general: Conocer y analizar los factores, sobre todo ambientales, que influyen en la conducta de actividad física de los niños y niñas en eda…

L'animismo rivisitato e i dibattiti sulle ontologie indigene

2014

Nell'articolo viene analizzata la recente interpretazione della nozione di animismo in antropologia legandola allo sviluppo del dibattito teorico sulle cosiddette 'ontologie indigene' e sui concetti di persona. Da questo punto di vista l'opera di Hallowell ha ispirato molti dei filoni di riflessione contemporanea su questi temi. Tra questi filoni, si possono annoverare: l'antropologia cognitiva di Boyer, l'antropologia fenomenologica di Ingold e Bird-David, la teoria degli schemi della pratica di Descola, la teoria del "prospettivismo amerindiano" di Viveiros de Castro. Dopo avere esaminato i caratteri e i limiti di ognuno di questi filoni, l'articolo si sofferma sulle posizioni più recenti…

Chemical composition of the essential oil from Thapsia garganica L. (Apiaceae) grown wild in Sicily and its antimicrobial activity.

2015

In this study, the chemical composition of the essential oil from flowers and leaves of Thapsia garganica L. collected in Sicily was evaluated by GC and GC-MS. The main components of T. garganica flower oil (T.f.) were chamazulene (58.3%), humulene oxide II (9.0%), tricosane (8.2%) and pentacosane (8.2%). Also the oil from leaves (T.l.) was characterised by high content of chamazulene (49.2%). Other abundant metabolites were 1,4-dimethylazulene (18.5%), (E)-phytol (6.3%) and neophytadiene (5.1%). The comparison with other studied oils of genus Thapsia is discussed. Antimicrobial activity against several micro-organisms, including some ones infesting historical art craft, was also determined.

Anti-inflammatory and antioxidant effects of ranolazine on primary cultured astrocytes

2014

Because of its ability to block late INa [1], ranolazine is used as an antianginal agent for the treatment of chronic angina pectoris when angina is not adequately controlled by other agents [2]. Besides its cardiovascular effects, ranolazine improves different neuronal functions, and thus its use has been proposed for the treatment of pain and epileptic disorders [3,4]. Since astrocytes are involved in neuronal inflammatory processes, and autoimmune and neurodegenerative diseases [5], we have investigated the antiinflammatory and antioxidant effects of ranolazine in primary cultured astrocytes.

Study on the sensitive and selective adsorption voltammetry of vanadium with antipyrylazo III (APA III)

1994

The sensitive and selective adsorption voltammetric determination of the vanadium(V)-antipyrylazoIII complex in HAc-NaAc solution is investigated. The V-complex is strongly adsorbed onto a stationary Hg-electrode and is reduced at a potential more negative than that corresponding to the reduction of its ligand. The conditions for determining vanadium are investigated and the mechanism of the reduction peak of the vanadium complex is discussed, as also the influence of foreign ions on the determination of vanadium. An at least 20-fold excess of foreign ions does not cause any interference. The detection limit is 4×10−10 mol/l V with 3 min enrichment time.
