Lumevis ™: a new medical device to prepare patients for esophagogastroduodenoscopy. Experimental clinical study.
2020
Esophagogastroduodenoscopy (EGDS) is the gold standard exam for upper gastrointestinal diseases. EGDS is very important in Early Gastric Cancer diagnosis and treatment but it is an operator-dependent exam and there are lots of factors that reduce its visibility (mucus, bubbles and foam).The aim of our study is to evaluate if the use of Lumevis™ improves mucosa visualization during EGDS without increasing the examination time and complications' rate and comparing the differences in patients prepared with water or no intervention.we recruited 50 patients from 01/08/2020 to 31/08/2020 who came to our observation for epigastric pain, dyspepsia and gastroesophageal reflux (GERD). For each patien…

Molecular tools to assess the diversity and density of denitrifying bacteria in their habitats
2007
Publisher Summary This chapter describes the molecular tools to assess the diversity and density of denitrifying bacteria in their habitats. Genome sequencing and metagenomic projects might even provide new denitrification gene sequences, which could aid in designing more broad range primers. Most information is obtained by cloning and sequencing the polymerase chain reaction (PCR) amplicons, but a more rapid analysis is achieved using fingerprinting techniques. As all PCR-based analyses, the fingerprinting techniques are subjected to well-known biases introduced by, e.g., DNA extraction procedures, primer selection, and PCR conditions. For denitrifiers, the PCR-RFLP (restriction fragment l…
Managing the flow of private information on children and parents in poverty situations : Creating a panoptic eye in interorganizational networks?
2018
In this article, we discuss how the flow of private information about children and families in poverty situations is managed in interorganizational networks that aim to combat child poverty. Although practices for sharing information and documentation between child and family social work services are highly encouraged and recommended to create supportive features for parents and children, this development often results in undesirable forms of governmentality. Interorganizational networking also creates controlling side effects because the exchange of information in networks of child and family services may wield a holistic power over families. We theorize this issue by using the Foucauldian…
Veure l'Edat Mitjana: el cinema com a espai de representació del món medieval
2010
El presente artículo pretende recordar la importancia del cine como recurso didáctico, como recurso que permite en ocasiones un acercamiento con rigor a las sociedades del pasado, y en concreto al mundo medieval. Explicamos la necesidad de acceder al cine como recurso didáctico utilizando previamente un método de análisis, y ofrecemos un ejemplo práctico de esta metodología mediante el análisis de la secuencia inicial de la película El manantial de la doncella (Jungfrukállan), dirigida por Ingmar Bergman en 1960.

La Sábana Santa y sus implicaciones histórico-artísticas
2017
RESUMEN DE LA TESIS DOCTORAL EN HISTORIA DEL ARTE “LA SÁBANA SANTA Y SUS IMPLICACIONES HISTÓRICO-ARTÍSTICAS” Realizada por Jorge-Manuel Rodríguez Almenar y dirigida por el Dr. D. Rafael García Mahíques Primera parte: LA SÍNDONE DE TURÍN La primera parte tiene la finalidad de conocer el objeto material sobre el que se ha construido la investigación subsiguiente: la llamada “Sábana Santa o Síndone de Turín”. Sin una base mínima de conocimientos no se puede entender el porqué del trabajo desarrollado posteriormente en las partes segunda y tercera. Sección I: Descripción de la Síndone. Siguiendo la metodología científica, lo primero que haré es describir materialmente el objeto. Y eso supone di…

Band-to-Band and Band-to-Acceptor Photoluminescence Studies in InSe under Pressure
1999
We report on photoluminescence (PL) measurements under pressure on p-type N-doped InSe at 10 K and on n-type Si-doped InSe at room temperature. Low-temperature PL of N-doped InSe is dominated by a band-to-acceptor peak. From the pressure dependence of the ionization energy of the N related shallow acceptor, the pressure change of the hole effective mass is estimated through the Gerlach-Pollmann model for hydrogenic levels in uniaxial crystals and discussed in the framework of a k p model. Room temperature PL in Si-doped InSe is dominated by a band-to-band peak exhibiting a pressure shift in agreement with previous works. This PL peak has been measured up to 7 GPa and a steep reversible decr…

Fundamentals of photoelectrocatalysis
2022
Photoelectrocatalysis combines heterogeneous photocatalysis and electrocatalysis principles for numerous processes including the degradation of harmful compounds, the generation of H2 and O2 from water splitting, the reduction of CO2 or the photoelectrocatalytic synthesis of valuable organic molecules otherwise difficult to be synthetized with classical approaches. The recent progress of photoelectrocatalysis is heavily related to the development of materials, especially in 2D and nano materials. Highly ordered nanomaterials such as graphene, nanotubes, nanowires, etc. are gaining more attention due to their high surface area and excellent conductivity. Other challenges are the development …
