Automātiska tīmekļa vietņu stila ģenerēšana
2017
Individuālas tīmekļa vietnes izstrāde ir sarežģīts process, kam nepieciešams daudz resursu, laika un specifisku zināšanu, taču internetā pieejamie rīki ne vienmēr spēj nodrošināt unikālu, vajadzībām atbilstošu risinājumu. Lai samazinātu nepieciešamos resursus un izstrādes laiku, tiek piedāvāta sistēma, kura tīmekļa vietnes stilu ģenerē, par pamatu izmantojot šīs vietnes saturu. Darba mērķis ir izstrādāt tīmekļa vietnes stila ģenerēšanas prototipu, izpētot literatūru un esošos risinājumus, lai atrastu pieeju un rīkus, uz kuriem balstīt risinājuma un prototipa izstrādi. Darba rezultātā tika veikts literatūras apskats, esošo risinājumu izpēte un izstrādāts risinājums tīmekļa vietnes stila un i…

Interferometric microscopy study of the surface roughness of Portland cement under the action of different irrigants
2013
Objectives: Some investigations suggested common Portland cement (PC) as a substitute material for MTA for endodontic use; both MTA and PC have a similar composition. The aim of this study was to determine the surface roughness of common PC before and after the exposition to different endodontic irrigating solutions: 10% and 20% citric acid, 17% ethylenediaminetetraacetic (EDTA) and 5% sodium hypochlorite. Study Design: Fifty PC samples in the form of cubes were prepared. PC was mixed with distilled water (powder/liquid ratio 3:1 by weight). The samples were immersed for one minute in 10% and 20% citric acid, 17% EDTA and 5% sodium hypochlorite. After gold coating, PC samples were examined …
Estilos parentales y valores: la socialización en derechos humanos a lo largo del ciclo vital
2015
El principal objetivo de esta tesis fue investigar la relación entre los diferentes estilos parentales de socialización y el ajuste psicosocial de los hijos de distintas generaciones. El ajuste psicológico se evaluó a través del auto-concepto y de la autoestima, el ajuste social se evaluó mediante las prioridades por los valores y el respeto por los Derechos Humanos (DDHH) (percepción del discurso de las madres sobre los DDHH, así como el compromiso de uno mismo hacia estos derechos). La muestra fueron 309 adolescentes entre 12 a17 años de edad (M = 14,36 años, SD = 1,69) y 217 mayores de 60 a 75 años (M = 63,38 años, SD = 3,45 años). En el ajuste psicológico, los resultados indicaron que h…
On-line solvent recycling: a tool for the development of clean analytical chemistry in flow injection Fourier transform infrared spectrometry. Determ…
1998
Abstract A flow injection strategy has been developed for the direct determination of ketoprofen in pharmaceuticals by Fourier transform infrared spectrometry also incorporating a distillation unit which allows the carbon tetrachloride employed to dissolve samples and standards and used as a carrier to be recovered on-line. The system developed permits a drastic reduction of reagent consumption and easy and fast sampling and cleaning of the measurement cell. For the quantification of ketoprofen in pharmaceuticals the carbonyl bands at 1712 and 1666 cm −1 were employed and the developed method provided a 3 σ limit of detection of 0.04 mg ml −1 , a dynamic range up to 10 mg ml −1 and typical …
Microwave-assisted vapour-generation Fourier transform infrared spectrometric determination of carbonate in waters
1998
Abstract A microwave-assisted vapour-generation Fourier transform infrared spectrometric procedure is proposed for the determination of total carbonate in waters. The method is based on the simultaneous injection of 100 μl of sample and 300 μl of 0.1 M nitric acid in a two-channel manifold with a merging zone; a coil located inside a microwave oven encourages the removal of CO 2 . The carbon dioxide is separated from the distilled water employed as carrier by means of gas–liquid separator and is introduced by a nitrogen carrier flow inside a long-path infrared absorption gas cell, from which the corresponding flow analysis recording is registered as a function of time in the wavenumber rang…
Atomic fluorescence determination of inorganic arsenic in soils after microwave-assisted distillation
2000
Abstract An inexpensive microwave-assisted distillation procedure has been developed for quantitative determination of inorganic arsenic in soils by atomic fluorescence spectrometry (AFS). After reduction of As(V) to its trivalent state with potassium iodide, inorganic arsenic was distilled as AsCl 3 that was finally determined by atomic fluorescence after hydride generation with NaBH 4 in HCl medium. The different parameters that control the distillation: concentration and volume of HCl, time of distillation, sample weight, and oven load, were studied. The methodology developed has a detection limit of 0.015 μg l −1 , which corresponds to a concentration of 0.006 μg of As per gram of soil,…
Different Sorption Behaviors for Wine Polyphenols in Contact with Oak Wood
2007
The evolution of polyphenols of enological interest- monomeric anthocyanins, (+)-catechin, (-)-epicatechin, gallic acid, and trans-resveratrol-in the presence of oak wood was investigated in aging-model conditions. Disappearance kinetics showed that, except for gallic acid, all of the wine polyphenols tend to disappear from the model wine in presence of oak wood, to reach an equilibrium after 20 days of contact. At equilibrium, the higher disappearance rates were obtained for monomeric anthocyanins and trans-resveratrol with values of 20 and 50%, respectively. For monomeric anthocyanins, the rate of disappearance seemed to be independent of their nature. In order to evaluate the contributio…
ASSESMENT OF TEMPERATURE POLARIZATION IN MEMBRANE DISTILLATION CHANNELS BY LIQUID CRYSTAL THERMOGRAPHY
2014
AbstractThe measurement of local temperature distributions within a membrane distillation (MD) channel is a crucial step for the optimization of the channel and spacer geometry. This information allows the estimation of temperature polarization phenomena, which can dramatically influence the thermal efficiency of the process and the optimal choice of the geometric configuration (net spacer features, channel size, etc.). In the present work, a recently presented experimental technique, based on the use of thermochromic liquid crystals and digital image analysis, has been employed in order to assess the temperature polarization phenomena. The local heat transfer coefficient distribution on th…
Educar jugando y dialogando. Derechos de la infancia, intencionalidad, familia y lenguaje
2019
[EN] The article reviews the rights that contribute to the achievement of a happy life from childhood and seizes on the key elements that seek dignity in order to develop happiness. First, the role of the family in setting up personal identity and security, and in establishing personal relationships. Second, the integral personal training and the education in the development of the critical sense and freedom for responsible exercise, as well as the ability to understand, express and communicate to improve or overcome problematic situations. Finally, gambling, as a basic tool of enjoyment in childhood, and, at the same time, learning in the two previous domains, sometimes unique complement o…
