Figueroles d'Alcalatén. Balls i costums

1999

Figueroles és una població de l'Alcalatén coneguda per una dansa tradicional emparentada amb les danses o dansades meridionals i els balls plans de les comarques septentrionals del País Valencià: el ball de l'Anguila, també conegut com el ball de Figueroles, una dansa que es va ballar per última vegada el dia de Sant Mateu de 1932 abans de la seua recuperació auspiciada pel treball investigador d'Amadeu Porcar, un dels autors d'aquest llibre, a l’any 1980. A més de l'Anguila, el patrimoni corèutic de Figueroles inclou la dansa del Prim, el ball de jota i el ball de plaça. A totes quatre manifestacions dediquen els autors el present estudi amb una petita descripció de la indumentària tradici…

Danish language tests for adult migrants

2016

In 1999, a new law on Danish language education came into force. In this law, the final examinations in Danish were introduced and set under national governance, and the requirements were defined. Since then the tests in Danish for adult migrants have developed and there has been an ongoing revision of both the language education and tests offered. nonPeerReviewed

Transglutaminase and polyamine dependence of effector functions of human immunocompetent cells

1982

AbstractThe effects of the transglutaminase inhibitor dansyl cadaverine (DC) and the polyamine antagonist methyl glyoxal-bis-(guanylhydrazone) (MeGbG) on the response of lymphocytes towards allogeneic and lectin stimulation and on the zymosan-induced chemiluminescence of neutrophilic granulocytes was studied. Application of DC resulted in dose-dependent suppression of chemiluminiscence and lymphocyte proliferation; no difference of inhibitory potential occurred with variation of incubation time in the latter system. MeGbG was inactive in granulocytes, but inhibited lymphocyte proliferation; its effect increased with time. The experiments provide further evidence for the importance of transg…

Development of an imaging system dedicated to the acquisition analysis and multispectral characterisation of skin lesion

2011

Visual evaluation of cutaneous lesions is the analysis the most commonly performedby dermatologists. This diagnostic is mainly done by naked eye and is based on criterionsuch as the size, shape, symmetry but principally on colour of the lesions. However, thisanalysis is subjective because it depends on the practician experience and the acquisitionconditions. We propose in this dissertation (1) the development of a multispectralcamera specifically dedicated for dermatological use. This device is based on a filterwheel composed of interferential filters and a neural network-based algorithm, generatinga hyperspectral cube of cutaneous data. This setting combines advantage of both spectrophotom…

Urine polyamines determination using dansyl chloride derivatization in solid-phase extraction cartridges and HPLC

1999

The derivatization of biogenic amines such as putrescine, cadaverine, spermidine and spermine with dansyl chloride in solid phase extraction cartridges is described. Different types of filling materials were tested in order to have the highest retention of the different analytes. The best results were obtained by using C18 cartridges. The optimal conditions were: amine solution buffered at pH 12, 2 mM dansyl chloride (acetone-bicarbonate solution 20 mM (pH 9-9.5), 2 + 3 v/v) as reagent concentration, room temperature and 30 min reaction time. The developed procedure was applied to the determination of these polyamines in urine samples from healthy controls and cancer patients using HPLC wit…

Selective determination of ammonium in water based on HPLC and chemiluminescence detection

2005

Abstract A selective and sensitive method has been developed for liquid chromatographic determination of ammonium in water samples. The analyte is derivatized with Dansyl Chloride prior to injection into HPLC. Optimal solution derivatization conditions have been established. The dansyl derivative is separated with the aid of a chromatographic column and post-column mixed with peroxyoxalate (TCPO) and H 2 O 2 in order to perform chemiluminescence detection. The detection limit achieved is 8 μg/L and linear response from 0.027 to 0.750 mg/L of ammonium was obtained. Ammonium ion was determined within 2.4 min under optimum chromatographic conditions. The method is fast, and near 10 derivatized…

Preconcentration and dansylation of aliphatic amines using C18 solid-phase packings

2002

Abstract Precolumn preconcentration and derivatization on solid sorbents (Bond Elut C18 solid-phase extraction cartridges) of low-molecular-mass aliphatic amines in water samples have been performed using dansyl chloride (Dns-Cl) as derivatization reagent. Conditions for analyte preconcentration and derivatization such as volume sample, reagent concentration, time, pH and temperature reaction were optimised. On the basis of these studies a rapid and sensitive method for screening of aliphatic amines in waters is presented. Up to volumes of 5 ml, samples are drawn through the sorbent, the analytes retained are dansylated at basic pH, at 100 °C for 10 min or 85 °C for 15 min. The derivatized …

The implication of subcortical motor centers in voluntary human activities

2009

The main objective of the present dissertation was to analyse the subcortical implications in the preparation and execution of complex voluntary movements. Three different tasks were selected on purpose. They all are everyday activities which although functionally related have differential characteristics. The first task was the sit-to-stand manoeuvre. Simple ballistic movements are executed faster in reaction time task paradigms when the imperative signal is accompanied by a startling auditory stimulus (SAS). We examined whether this effect also occurs in complex movements such as the sit-to-stand manoeuvre, taking into account both anticipatory postural adjustments and prime movers. React…

Valoración de las capacidades físicas y cognitivas en corredores de orientación de la categoría hombres-élite.

2004

El deporte de orientación consiste en realizar un recorrido en el menor tiempo posible y con la única ayuda de un mapa y una brújula, teniendo la particularidad de que cada corredor puede elegir la ruta de desplazamiento de un control a otro. Esto propicia que nos encontremos ante un deporte en el que los aspectos perceptivo-cognitivos van a ser fundamentales.El objetivo de este estudio fue caracterizar a la población española de la categoría hombres-élite, que es la máxima categoría a nivel nacional, con el fin de poder crear pautas de entrenamiento adecuadas.Para ello, realizamos una comparativa entre los corredores de élite (total: 23 corredores) y los participantes del resto de categorí…
