Influencia de la estimulación cerebral profunda de la corteza infralímbica sobre un modelo farmacológico de ansiedad en rata. Estudio anatomofunciona…
2022
La ansiedad y la depresión son las enfermedades mentales más prevalentes en todo el mundo. Ambas exhiben una alta comorbilidad, afectan especialmente a mujeres y comparten la alteración del circuito amígdalo-hipocámpico-prefrontal, que está involucrado en la gestión emocional y cognitiva que se encuentra alterada en ambas patologías. La estimulación cerebral profunda de la corteza infralímbica, así como su equivalencia anatómica en humanos, la corteza cingulada anterior, constituye un tratamiento antidepresivo -rápido. Sin embargo, sus mecanismos de acción siguen siendo a día de hoy parcialmente desconocidos. En este trabajo se intenta ahondar en la implicación sexualmente diferenciada del …
Loading carbonaceous materials with silver for the treatment of chloro-organic compounds in aqueous phase
2012
Many electrochemical technologies, either based on novel concepts (such as microbial fuel cells), experimental setups (such as photoelectrochemical or solar photoelectro-Fenton reactors) or materials (mainly focused on the use of large O2-overpotential anodes like BDD) have been devised in recent years for water remediation. Special attention has been paid to highly toxic, biorefractory organic pollutants such as the chlorinated hydrocarbons, which conjugate toxicity with chemical stability, bioaccumulation and long-range diffusivity [1]. Electroreduction at silver cathodes becomes an interesting alternative to degrade chloro-organic compounds, but it may lead to the accumulation of reactio…
Removing ocular artifacts from magnetoencephalographic data on naturalistic reading of continuous texts
2022
Naturalistic reading paradigms and stimuli consisting of long continuous texts are essential for characterizing the cortical basis of reading. Due to the highly dynamic nature of the reading process, electrophysiological brain imaging methods with high spatial and temporal resolution, such as magnetoencephalography (MEG), are ideal for tracking them. However, as electrophysiological recordings are sensitive to electromagnetic artifacts, data recorded during naturalistic reading is confounded by ocular artifacts. In this study, we evaluate two different pipelines for removing ocular artifacts from MEG data collected during continuous, naturalistic reading, with the focus on saccades and blin…
Nātrija bismuta titanāta un uz tā bāzes veidotu cieto šķīdumu elektromehāniskās īpašības
2019
Apzinoties svina negatīvo ietekmi uz dabu, pēdējo 20 gadu laikā zinātnieki arvien lielāku uzmanību ir pievērsuši svinu nesaturošu segnetoelektrisko materiālu pētīšanai. Viens no šādiem materiāliem ir nātrija bismuta titanāts (NBT), kura elektromehāniskās īpašības potenciāli varētu būt samērojamas ar šobrīd ierīcēs izmantotiem materiāliem un atsevišķos pielietojumos jau pārspēj tos. Darbā tiek pētīts gan tīrs NBT, gan tā savienojumi ar lantanīdiem – erbiju un iterbiju –, kā arī cietie šķīdumi ar nātrija niobātu (NaNbO3), bārija titanātu (BaTiO3) un kalcija titanātu (CaTiO3). Darba mērķis ir noskaidrot, kāda ir piedevu ietekme uz materiāla elektromehāniskajām īpašībām un kā tās mainās tempera…
Experimental study of electron transport in mesoscopic carbon based nanostructures
2012
In this thesis we have studied experimentally electronic transport in mesoscopic hybrid polypyrrole-gold devices and single multiwalled carbon nanotube devices. A novel fabrication technique for mesoscopic conducting hybrid polymer-gold films has been developed. The hybrid polymer-gold films have been fabricated by electrochemical deposition of polypyrrole on a gold nanoisland layer. Temperature dependence of conductance show that the dominant transport mechanism in the polypyrrole-gold films is variable range hopping in the temperature range from 20 K to 300 K. At very low temperature strong nonlinearities in the field dependent conductance are observed. The field dependence follows a phen…

Social Inclusion and Exclusion in the Life Stories of Deported Asylum Seekers from Finland to Iraqi Kurdistan
2018
This study explores how social inclusion and exclusion manifest as a dynamic continuum in the everyday lived realities of irregular migrants. Based on narratives of Iraqi Kurdish asylum seekers, who were eventually deported from Finland, the analysis depicts the ways in which societal structures, personal negotiations as well as relationships and social networks interplay in lives characterized by multiple locations, transitions and positions. Establishing and maintaining social contacts, belonging to various networks and being able to decide and act are primary factors that help us understand how the narrators relate to the continuum. The participants construct narratives illustrating seve…
La politique sportive des Emirats du Golfe : comment obtenir une visibilité internationale ?
2006
Les petits Emirats du Golfe Persique ont choisi le sport pour obtenir une visibilité internationale et modifier leur image. Le sport offrait la possibilité d’afficher une modernité souvent associée à l’adoption de valeurs venues de l’Occident. Sans traditions sportives et très peu peuplés, ces Etats ont néanmoins réussi leur entrée sur la scène sportive internationale en mobilisant beaucoup d’argent. Ils ont pu ainsi accueillir et organiser des compétitions sportives internationales de grande ampleur et se faire reconnaître. Leur politique a franchi un nouveau pas, depuis quatre années, en naturalisant des athlètes de haut niveau pour obtenir des médailles car en terme de communication, l’i…
