Highly sensitive temperature and strain sensors based on all-fiber 45°-TFG Lyot filter

We demonstrate highly sensitive temperature and strain sensors based on an all-fiber Lyot filter structure, which is formed by concatenating two 45°-TFGs (tilted fiber gratings) with a PM fiber cavity. The experiment results show the all-fiber 45°-TFG Lyot filter has very high sensitivity to strain and temperature. The 45°-TFG Lyot filters of two different cavity lengths (18cm and 40 cm) have been evaluated for temperature sensing by heating a section of the cavity from 10°C to 50°C. The experiment results have shown remarkably high temperature sensitivities of 0.616nm/°C for 18cm and 0.31nm/°C for 40cm long cavity filter, respectively. The 18cm long cavity filter has been subjected to strain variations up to around 550μ ε and the filter has exhibited strain sensitivities of 0.02499nm/μ ε and 0.012nm/μ ε for two straining situations, where its cavity middle section of 18cm and 9cm were stretched, respectively. © 2012 SPIE.

Optical loading sensor based on single polarization fiber laser incorporating an intra-cavity 45°-TFG

We have experimentally demonstrated an active loading sensor system based on a fiber ring laser with single-polarization output using an intra-cavity 45°-tilted fiber grating (45°-TFG). When the laser cavity fiber subjected to loading, the laser output is encoded with the load and can be measured and monitored by a power metre. A loading sensitivity as high as 0.033/ (kg·m-1) has been achieved using this laser. The experiment results clearly show that single polarization fiber laser may be developed to a low-cost high-sensitivity loading sensor system. © 2014 SPIE.

Numerical and experimental analysis of sensitivity-enhanced RI sensor based on Ex-TFG in thin cladding fiber

We report a highly sensitive refractive index (RI) sensor in the aqueous solution, which is based on an 81°-tilted fiber grating structure inscribed into a thin cladding fiber with 40 μm cladding radius. The numerical analysis has indicated that the RI sensitivity of cladding resonance mode of the grating can be significantly enhanced with reducing cladding size. This has been proved by the experimental results as the RI sensitivities of TM and TE resonance peaks in the index region of 1.345 have been increased to 1180 nm/RIU and 1150 nm/RIU, respectively, from only 200 and 170 nm/RIU for the same grating structure inscribed in standard telecom fiber with 62.5-μm cladding radius. Although the temperature sensitivity has also increased, the change in temperature sensitivity is still insignificant in comparison with RI sensitivity enhancement.

Sensitivity enhanced SRI sensor based on an Ex-TFG in thin cladding fiber

A high sensitivity SRI sensor was fabricated by inscribing an ex-TFG in a thin cladding fiber, achieving enhanced SRI sensitivities of the TM and TE resonance peaks around 1180nm/RIU and 1150nm/RIU at the index of 1.345. © 2014 OSA.

45°-TFG based in-fiber polarizer at 800nm by UV inscription

We show in-fiber polarizers at 800nm range with polarization extinction ratio (PER) up to 37dB, fabricated by UV-inscribing grating structures tilted at 45° in standard single mode fiber. The results show that the PER of such polarizers increases linearly with the grating length. © OSA 2012.

Barcelona: Espacio literario, espacio urbano en la novela Catalana femenina del Siglo XX

This dissertation analyses, through a rhetorical framework and a literary approach, texts written in Catalan and Castilian by four Catalan female writers (Dolors Monserdà, Maria Aurèlia Capmany, Esther Tusquets, Monserrat Roig ), whose works cover from 1900 to the 1980. Utilizing this urban feminine literature, it discusses the historical-geographical vision about the changes in Catalan society during the twentieth century with its consequences for the urban space, especially the space occupied by women. It is also established that Barcelona's recovery and literary vindication by women has been done through the written text, as literary affirmation and as a matter of conscience in which the city could not be summed up as a backdrop, but rather as an active part of a literary creation, active in the double sense, as a socio-historical space in the novel and as characteristic of their works. The primary purpose of this dissertation is to demonstrate that the use of the city as a setting for the novels determines and characterizes those female writers' texts. Consequently, these writings are literary material relevant and essential to the understanding of the Barcelonian women's space. However their use of space is not arbitrary, on the contrary it corresponds to a social order established by the patriarchy where the relation of women to the world is embodied in the intentional and socially restricted space and movements of their bodies. The theoretical perspectives of this study are based on Montserrat Roig's feminist urban space theories. Her theory advocates the right to individuality, denouncing the patriarchal and hierarchical social system present in gendered space from the outside male world to the domestic feminized space. I also turn to the writings of Maria Aurèlia Capmany, who addresses cultural aspects of women's roles revealing a purposive controlled patriarchal society according to a historical-geographical analysis. This study of texts permits a new reading of the Catalan capital and demonstrates that Catalan women writers have consciously willed to give birth to a new history of the city: the history of women as protagonist citizens, producers, reproducers, and consumers of the space represented by the Catalan capital

"Amor de don Perlimplín con Belisa en su jardín": una obra teatral satírica

El componente satírico es una constante en el teatro de Federico García Lorca, en el que coexisten, en mayor o menor medida, dependiendo de la obra en cuestión, lo cómico y lo serio, ambas vertientes intrínsecas a la sátira. Dicha combinación, así como el innegable aspecto crítico, inherente a la obra lorquiana, identifican a este autor con la figura del satírico. García Lorca lleva a cabo su crítica sirviéndose del humor, que oscila entre lo puramente jocoso y el humor negro, y se manifiesta mediante el empleo de técnicas tradicionales de la sátira, con idéntico propósito al del satírico: degradar a su objeto de ataque suscitando sonrisa o repulsa. Este artículo analiza en clave de sátira Amor de don Perlimplín con Belisa en su jardín, identificando el objeto de ataque de la sátira lorquiana en esta obra y las técnicas satíricas empleadas por su autor.

La fijación léxica en el "Corpus diacrónico del español del Reino de Granada (CORDEREGRA)"

El estudio de las combinaciones léxicas según su grado de fijación y su distinción en combinaciones libres, colocaciones y locuciones ha sido realizado desde la perspectiva sincrónica. Planteamos la posibilidad de aplicar las pautas para distinguir estos tipos de estructuras en materiales de tipo diacrónico. Concretamente, nos basamos en los documentos que componen el Corpus del Español del Reino de Granada (CORDEREGRA) para valorar los materiales de este corpus histórico-lingüístico y comprobar si los criterios sincrónicos se pueden aplicar al estudio de documentos de otros siglos.

TFG Promotes Organization of Transitional ER and Efficient Collagen Secretion

Collagen is the most abundant protein in the animal kingdom. It is of fundamental importance during development for cell differentiation and tissue morphogenesis as well as in pathological processes such as fibrosis and cancer cell migration. However, our understanding of the mechanisms of procollagen secretion remains limited. Here, we show that TFG organizes transitional ER (tER) and ER exit sites (ERESs) into larger structures. Depletion of TFG results in dispersion of tER elements that remain associated with individual ER-Golgi intermediate compartments (ERGICs) as largely functional ERESs. We show that TFG is not required for the transport and packaging of small soluble cargoes but is necessary for the export of procollagen from the ER. Our work therefore suggests a key relationship between the structure and function of ERESs and a central role for TFG in optimizing COPII assembly for procollagen export.

La evaluación de los TFG: criterios, formas y experiencias en la Facultad de Derecho de la UCM

La asignatura Trabajo Fin de Grado (TFG) es una asignatura totalmente novedosa para las ramas de las ciencias jurídicas. En la Facultad de Derecho de la UCM, en concreto en el Grado en Derecho, su implantación se ha realizado muy recientemente, contando con apenas dos años de experiencia. El presente trabajo tiene por objeto analizar las formas y criterios de evaluación del TFG adoptadas en la Facultad de Derecho, y el desarrollo de las mismas que han realizado los distintos departamentos, realizando una valoración de la experiencia adquirida durante estos primeros años de implantación.

El TFG: sus modalidades, objetivos y competencias a validar. Reflexiones a partir de la experiencia en la Facultad de Derecho de la UCM

El trabajo que se presenta se centra en dos aspectos que son fundamentales en el diseño y desarrollo de los TFG: Por una parte, los objetivos y competencias a validar en el TFG y, por otra, las modalidades que puede revestir dicho trabajo. Se trata de individualizar estos elementos en el marco regulador correspondiente y analizar cómo se desarrollan en el diseño de los TFG del Grado en Derecho en la UCM, y más concretamente los que son tutorizados en el Departamento de Derecho Constitucional. Finalmente se trata de individualizar los posibles problemas y aportar algunas reflexiones sobre su tratamiento académico.
