Plasma Functionalization of Multiwalled Carbon Nanotubes and Their Use in the Preparation of Nylon 6-Based Nanohybrids

2012

The possibility to obtain carbon nanotubes (CNT)/polyamide 6 composites with excellent mechanical properties in a simple, industrially scalable way is investigated. Commercial CNTs are treated by plasma while changing some key parameters (exposure time, plasma power, type of gas) in order to optimize the process and to achieve a sufficient degree of functionalization. The treated samples are characterized by Fourier transform infrared spectroscopy, Raman spectroscopy and X-ray photoelectron spectroscopy. The most interesting samples are selected to be used as reinforcing fillers, in different concentrations, in a polyamide 6 matrix. The mechanical tests show a dramatic increase of both tens…

‘‘What an Eccentric Performance" : Storytelling in Online Let's Plays

2019

In this article, I examine the phenomenon called Let’s Play (LP) and conduct a narrative analysis on two LPs made of Sierra Entertainment’s Phantasmagoria games. The LPs tell viewers a story different from the one told in the games, that is, they tell the story of the player rather than that of the game. In that story, the experience of playing a video game is revealed to the audience. This story would be hidden without the player-narrators know as LPs around the world. I conduct my analysis by describing seven different narrative elements that form the narration of a LP and explain how these elements together form this story of the player. peerReviewed

Amygdaloid projections to the ventral striatum in mice: direct and indirect chemosensory inputs to the brain reward system

2011

Rodents constitute good models for studying the neural basis of socio-sexual behaviour. Recent findings in mice have revealed the molecular identity of the some pheromonal molecules triggering intersexual attraction. However, the neural pathways mediating this basic socio-sexual behaviour remain elusive. Since previous work indicates that the dopaminergic tegmento-striatal pathway is not involved in pheromone reward, the present report explores alternative pathways linking the vomeronasal system with the tegmento-striatal system (the limbic basal ganglia) by means of tract-tracing experiments studying direct and indirect projections from the chemosensory amygdala to the ventral striato-pall…

Coding emotions in computer-mediated communication: the example of YouTube comments

2018

Computer-mediated communication (CMC) is essentially text-based. This is generally said to result in a “paucity of paralinguistic and non-linguistic cues” (Bieswanger, 2013: 468), but it is also considered to be the main reason for the development of other characteristic non-verbal modalities, such as emoticons and emoji. How are, then, emotions expressed in such a specific context? Are verbal modalities as limited as they are said to be? Do non-verbal modalities complete or replace them? This paper will try to answer those questions using discourse analysis tools applied to a sample of comments on a YouTube video.

Randomized trial of primary debulking surgery versus neoadjuvant chemotherapy for advanced epithelial ovarian cancer (SCORPION-NCT01461850)

2020

ObjectiveTo investigate whether neoadjuvant chemotherapy followed by interval debulking surgery is superior to primary debulking surgery in terms of perioperative complications and progression-free survival, in advanced epithelial ovarian, fallopian tube or primary peritoneal cancer patients with high tumor load.MethodsPatients with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer (stage IIIC-IV) underwent laparoscopy. Patients with high tumor load assessed by a standardized laparoscopic predictive index were randomly assigned (1:1 ratio) to undergo either primary debulking surgery followed by adjuvant chemotherapy (arm A), or neoadjuvant chemotherapy followed by int…

Prettuberkulozes medikamentu izraisītās blakusparādības un to ietekme uz ārstēšanās procesu.

2015

Bakalaura darba tēma ir „Prettuberkulozes medikamentu izraisītās blakusparādības un to ietekme uz ārstēšanās procesu”. Pētījuma tēma ir aktuāla, jo vēl arvien ir daudz pacientu, kuri prettuberkulozes terapiju saņem stacionārā, medikamentu izraisīto blakusparādību dēļ. Darba mērķis ir noskaidrot tuberkulozes pacientiem radušās blakusparādības terapijas laikā un no tām izrietošās sekas. Pētījuma rezultāti kalpotu par pamatu nepieciešamībai ieviest vienotu tuberkulozes pacientu apmācības standartu, kas veicinātu pacientu zināšanas un izpratni par nozīmēto prettuberkulozes terapiju un tās blakusparādībām, kurām nepieciešams pievērst uzmanību. Pētniecības darba jautājums: Kā prettuberkulozes med…

Application of Broadband Dielectric Spectroscopy to Cultural Heritage: characterization and preservation of ancient paper artwork

2016

Within the cultural heritage the characterization and conservation of artworks based on paper represents a significant issue for both restorers and scientists. The paper deterioration is affected by the degree of hydrolytic and oxidative reactions which occur upon aging. Moreover, the durability of cellulose fibers depends on the intrinsic composition/structure of the paper as well as on the conservation conditions, such as temperature and humidity. The structural and dynamical characterization of the cellulose matrix and of the water confined within its pores is therefore of central interest. Our working hypothesis is that WATER DYNAMICS is one of the main determinants of paper degradation…

Utilidad de la tomografía computarizada en el diagnóstico de la tuberculosis en niños

2015

Tras la primoinfección, la mayoría de los pacientes desarrollan una infección tuberculosa latente (ITL), pero un porcentaje evoluciona a enfermedad tuberculosa (ET). Es importante diferenciar estas entidades dado que requieren pautas de tratamiento diferentes. El diagnóstico de la tuberculosis (TB) depende, con frecuencia, de la detección de anomalías en la radiografía de tórax. Las adenopatías son el hallazgo radiológico más frecuente. Sin embargo diferentes autores han demostrado que la radiografía de tórax tiene poca sensibilidad y especificidad para su detección. La tomografía coputarizada (TC) se considera la modalidad radiológica de elección para la detección de las adenopatías, pero …
