EVOLUTION OF ENDOGENOUS GIBERELLINS AT DIFFERENT STAGES OF FLOWERING IN RELATION TO RETURN BLOOM OF CACTUS PEAR (OPUNTIA FICUS-INDICA (L.) MILLER)

1998

Abstract The effect of flower emasculation, flower injection with paclobutrazol and the complete removal of the spring flush of flowers and cladodes on the changes in GA 3 concentration at different stages of bloom in flowers and fertile cladodes of Opuntia ficus-indica has been determined. Throughout the bloom period, the concentration of GA 3 was higher in intact flowers and the cladode than in flowers emasculated or injected with paclobutrazol. With the onset of blooming, GA 3 started to accumulate both in the flower and in the fertile cladode, and the highest concentration was measured at full bloom in the flower and in the cladodes whose flowers were not removed. Flower emasculation or…

Patient-specific simulation of the intrastromal ring segment implantation in corneas with keratoconus

2015

Purpose The purpose of this study was the simulation of the implantation of intrastromal corneal-ring segments for patients with keratoconus. The aim of the study was the prediction of the corneal curvature recovery after this intervention. Methods Seven patients with keratoconus diagnosed and treated by implantation of intrastromal corneal-ring segments were enrolled in the study. The 3D geometry of the cornea of each patient was obtained from its specific topography and a hyperelastic model was assumed to characterize its mechanical behavior. To simulate the intervention, the intrastromal corneal-ring segments were modeled and placed at the same location at which they were placed in the s…

Disease expression in women with hereditary angioedema

2008

Udgivelsesdato: 2008-Jun-11 OBJECTIVE: Fluctuations in sex hormones can trigger angioedema attacks in women with hereditary angioedema. Combined oral contraceptive therapies, as well as pregnancy, can induce severe attacks. The course of angioedema may be very variable in different women. STUDY DESIGN: Within the PREHAEAT project launched by the European Union, data on 150 postpubertal women with hereditary angioedema were collected in 8 countries, using a patient-based questionnaire. RESULTS: Puberty worsened the disease for 62%. Combined oral contraceptives worsened the disease for 79%, whereas progestogen-only pills improved it for 64%. During pregnancies, 38% of women had more attacks, …

Current drugs in early development for hereditary angioedema: potential for effective treatment

2014

Hereditary angioedema (HAE) through C1 inhibitor deficiency is a rare but important disease. It is characterized by recurrent episodes of angioedema, which commonly affects the skin (in the form of swelling in the extremities, face and genitals) as well as the gastrointestinal tract (abdominal pain attacks). In approximately 1% of cases of angiodema-related swelling, there is obstruction of the upper airway, which is potentially life-threatening. Therefore, HAE due to C1 inhibitor deficiency may be associated with significant morbidity and mortality. Recent research has added to our ever-increasing understanding of the pathogenesis of HAE, which has, in addition, new clinical trials with ne…

The UWB-OFDM Channel Analysis in Frequency

2009

In this paper, the ultra-wideband channel with orthogonal frequency division multiplexing (UWB-OFDM) is analyzed in the frequency domain. For UWB-OFDM channels with log-normal fading in the time domain, we show that the amplitude of each subcarrier can be approximated by a Nakagami-m random variable, where the fading parameter, the mean power and the correlation coefficient are expressed in terms of the following parameters: time arrival of the clusters, inter-arrival time of rays inside clusters, and power decay constants of rays and clusters.

Generalized Conformal Symmetry and Extended Objects from the Free Particle

1998

The algebra of linear and quadratic functions of basic observables on the phase space of either the free particle or the harmonic oscillator possesses a finite-dimensional anomaly. The quantization of these systems outside the critical values of the anomaly leads to a new degree of freedom which shares its internal character with spin, but nevertheless features an infinite number of different states. Both are associated with the transformation properties of wave functions under the Weyl-symplectic group $WSp(6,\Re)$. The physical meaning of this new degree of freedom can be established, with a major scope, only by analysing the quantization of an infinite-dimensional algebra of diffeomorphi…

El presente artículo pretende una aproximación iconográfica a la obra plástica de Antonio Muñoz Degraín (1840-1924) inspirada tanto en las aventuras del Quijote como en las desventuras de su celebrado autor. Por tanto, formarán parte de este estudio todas las pinturas que el artista valenciano realizó, entre los años de 1916 y 1919, para ser colgadas en las paredes de la sala Cervantes de la Biblioteca Nacional, cuya inauguración se produjo el 6 de marzo de 1920.

An empirical approach for evaluating the usability of model-driven tools

2013

MDD tools are very useful to draw conceptual models and to automate code generation. Even though this would bring many benefits, wide adoption of MDD tools is not yet a reality. Various research activities are being undertaken to find why and to provide the required solutions. However, insufficient research has been done on a key factor for the acceptance of MDD tools: usability. With the help of end-users, this paper presents a framework to evaluate the usability of MDD tools. The framework will be used as a basis for a family of experiments to get clear insights into the barriers to usability that prevent MDD tools from being widely adopted in industry. To illustrate the applicability of …

Hacia un Índice de Política Social: La Utilización de la propuesta de UNRISD para comparar 3 países de la OCDE con distinto Estado de Bienestar: Chile, España y Reino Unido. Doctorando: Gustavo Castillo Rozas Directores: Dr. Jorge Garcés - Dr. Francisco Ródenas En el año 2006, el Instituto de Investigación para el Desarrollo Social de Naciones Unidas –UNRISD para sus siglas en inglés- da a conocer un Índice de Política Social, que se encarga no de medir los resultados de las políticas, si no que de medir los esfuerzos de los gobiernos en materia de política social, es decir, no se fija en los outcomes (salidas o productos), si no que en los inputs (entradas). El SPI (siglas en inglés), es p…
