Pronóstico de la hemorragia subaracnoidea espontánea aneurismática y su correlación con escalas de gravedad, escalas de calidad de vida y tratamiento…
2015
La hemorragia subaracnoidea (HSA) corresponde a uno de los tipos de hemorragia intracraneal en el que se produce una extravasación de sangre en el espacio subaracnoideo o leptomeníngeo. La causa más frecuente es el traumatismo craneoencefálico y en segundo lugar el sangrado espontáneo. La HSA primaria o espontánea se produce, con mayor frecuencia, por la ruptura de una aneurisma cerebral. La HSA es el subtipo de ictus menos frecuente pero es el que cualitativamente mayor morbimortalidad produce. La carga sociosanitaria que representa es aún más pesada dado que incide en un porcentaje relevante de los casos sobre personas jóvenes, previamente sanas y completamente independientes. A pesar de …

Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at √s = 7 TeV
2017
Two-particle angular correlations were measured in pp collisions at s√=7 TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected peak dominated by effects associated with mini-jets and are well reproduced by general purpose Monte Carlo generators. However, for baryon–baryon and anti-baryon–anti-baryon pairs, where both particles have the same baryon number, a near-side anti-correlation structure is observed instead of a peak. This effect is interpreted in the context of baryon production mechanisms in the fragmentation process. It currently presents a challenge to Monte Carlo models and its origin remains an op…
Práctica y cultura musical en Valencia en el siglo XVII
2020
La presente tesis doctoral muestra un estudio del oficio musical en Valencia en el siglo XVII a través de la consulta y el análisis de las fuentes documentales de los principales archivos de la ciudad, con el propósito de contribuir a la reconstrucción del patrimonio cultural valenciano. El trabajo parte de un sucinto recorrido en torno al origen medieval y la modificación de los códigos rituales, en cuyo proceso de implementación el Consell centraliza la promoción artística y se erige en el principal mecenas del producto musical. El modelo de práctica instrumental que desarrolla el consejo municipal verifica la inserción oficial y nominal de los instrumentistas, casuística que se irradia a…

Estar al otro lado de la mesa. Profesionales de los servicios públicos de empleo ante los dilemas de la activación laboral
2019
Under the paradigm of activation, the Public Employment Services has been reshaped by two levels of contractualization. On one hand, the collaboration of the administration with a network of agents on the programme scheme that make up the active policies of employment. On the other hand, the unemployed person?s access to a compartmentalized offer of services and individually taking responsibility for finding work. This double contractualization reveals redefinition of lowering public responsibility faced with the problem of unemployment that this activation supposes. This paper analyses how this redesign has an impact on how professionals serve the unemployed population. This lays bare, in …
Intellectual Property Rights: An Economic Approach
2014
Abstract This paper aims to analyse the intellectual property rights from an economic perspective. The paper is discussing the points of view of well known economists in relation to the positive and negative impacts of the intellectual property systems. It brings also into discussion the role of IPR as a barrier to entry and a mean to restrict competition and to favour monopoly situations.
Contrattazione collettiva e responsabilità dirigenziale
2020
The article describes the limits that the law formally assigns to collective bargaining in the matter of public managers’ liability before focusing on an analysis of the effects that contractual regulations have produced (and produce) in the general field of the allocation, revocation and renewal of senior positions. Based on this survey, the paper highlights the inconsistencies of some (both interpretative and de iure condendo) proposals, generally shared by a majority of scholars.
Purification and partial characterization of aminopeptidase from barley (Hordeum vulgare L.) seeds.
2013
Aminopeptidases (EC 3.4.11) are proteolytic enzymes, which hydrolyze one amino acid from N-terminus of peptidic substrates. Inhibitors of plant aminopeptidases can find an application in agriculture as herbicides. Isolation and partial characterization of aminopeptidase from barley (Hordeum vulgare L.) seeds has been described. The enzyme was purified to molecular homogeneity using a six-step purification procedure (precipitation with (NH4)2SO4, followed by chromatography on Sephadex G-25, DEAE-Sepharose, Sephacryl HR 300, Macro-Prep Q and Phenyl-Sepharose HP columns). The enzyme was purified 365-fold with recovery above 18%. The molecular weight of the purified enzyme was determined by SDS…
Inovatīva RF induktora barotāja datormodelēšana, izstrāde un eksperimenti
2018
Darbā tiek apskatītas dažādas iespējas ģenerēt augstas jaudas signālu ar atsevišķi regulējamu PWM (jaudas) koeficientu un frekvenci līdz 3 MHz. Tiek iztirzāti dažādi varianti praktiskā darba izpildei. Mūsdienās prasības germānija kristālu tīrībai aizvien aug un to audzēšana bezkontakta iekārtās var dot vajadzīgo rezultātu. LU ASI Atomfizikas un atmosfēras fizikas un fotoķīmijas laboratorijas efektīvās sadarbības projektā ar “Baltic Scientific Instruments Ltd” (lieto augstākās tīrības germānija kristālus) tika noskaidrots ka germānija kausēšanai vakuuma magnētiskajā levitācijā nepieciešams 30 kW un 0,5 - 3 MHz impulsa platumā regulējams (10 - 100% no jaudas) ģenerators, kas diemžēl komerciāl…
