Inplante erabilerako polimero erradio-opakoen lorpena eta ezaugarritzea

[EU]Biomedikuntzan gero eta material polimeriko gehiago aplikatzen dira. Metalezko inplanteekin alderatuz, ekoizterako orduan azkarragoak eta merkeagoak baitira beste hainbat ezaugarriren artean. Baina onurak ekartzearekin batera, erradio-opakotasun eza ere badakar. Eta ezaugarri hau gabe, inplantearen jarraipena behin giza gorputzean ezarrita dagoenean ezinezkoa da, X izpiekin ezin baita ikusi. Beraz, arazo horri aurre egiteko, proiektu honetan matrize polimerikoari kargak gehitzea proposatzen da. Lortutako material konposatuak, polimeroak soilik dituen ezaugarriak berdintzea edo hobetzea espero da. Hau da, erradio-opakotasuna lortzeaz gain, propietate mekanikoak behintzat mantentzea espero da. Giza gorputzean aplikatzen diren inplanteetarako erabiliko den material konposatu bat lortzea duenez helburu proiektu honek, matrizea polimero biobataragarria eta biodegradagarria izango da. Biodegradagarria izanik, inplantea kanporatzeko bigarren ebakuntza bat ekiditen da. Zehazki, poli(D-laktida) (PDLA) polimeroa matrize moduan eta karga moduan bismuto oxidoa (Bi2O3) erabiliko dira, medikuntza arloko inplanteetan erabili izan ohi dira eta.

Aerosorgailu palen aplikazioetarako pvc espumaren degradazio termiko eta propietate mekanikoen karakterizazioa

[EU]Energia berriztagarria iturri naturaletatik sortzen den energia mota da. Energia lortzeko erabiltzen diren baliabide naturalak asko dira, eguzki-energia, haizea, ura… Energia berriztagarrien artean, eolikoa da zabalkunde handien lortu duena; batez ere ingurumen-inpaktu urriagatik eta bere kostuak gero eta txikiagoak izateagatik. Honen ondorioz, energia garbi, lehiakor eta ekonomikoki bideragarria da gaur egun. Hala ere, aerosorgailu hauen ekoizpen prozesuak desabantaila nabaria aurkezten du palen ontze prozesuan. Tenperatura igoeraren ondorioz material konkretu baten degradazioa dela eta. Ikerketa lan honetan, aerosorgailu palen karakterizazioa egingo da eta ontze prozesuan, “polikloruro de binilo” (PVC)-ak jasaten duen degradazioaren azterketa.

Enfoque diferencial de edad en la política de reparación individual dirigida a niños, niñas y adolescentes víctimas del conflicto armado en Colombia

Teniendo en cuenta que la reparación es un derecho con características particulares, especialmente para la infancia y la adolescencia, la presente investigación revisa los alcances del enfoque diferencial de edad en esta política en Colombia. Para cumplir este objetivo se realizó un análisis de la legislación internacional, legislación nacional actual y como un caso tipo, el Decreto de Reparación Individual Administrativa (Decreto 1290 de 2008). De esta forma, se ubica respecto a la reparación desde una visión subjetivista de los derechos humanos, entendiéndola no solo como una obligación del Estado sino como un derecho en sí mismo, y por lo tanto en este marco, revalora el enfoque diferencial de edad como un reto de la política concibiéndolo como la intencionalidad de la sociedad y el Estado de consolidar legislaciones y prácticas sociales sensibles a las subjetividades, necesidades y demandas de los niños, las niñas y los adolescentes como respuesta al principio de igualdad para incluirles como ciudadanos y superar la hegemonía del discurso adultocéntrico. De este modo, se constituye como aporte para las instituciones que tienen el deber de incluir el derecho a la reparación integral de la infancia y la adolescencia en la formulación y ejecución de la política pública y contribuye para que los niños, niñas y adolescentes sean visibilizados de manera efectiva en los mecanismos y procedimientos diseñados para tal fin en Colombia.

When the rising dragon sees fading stars: China's view of the European Union. CEPS Special Report No. 73, 29 November 2012

This CEPS Special Report gives an overview of China’s perceptions of the EU and the protection of Chinese investments in Europe since the outbreak of the European sovereign debt crisis, especially since the more concrete talks in late 2011 on possible financial support from China. Although the top leadership of the communist party of China (CPC) changed in its recent handover, the perceptions described in this paper are likely to remain the same, just as the main tenets of China’s foreign policy are unlikely to change in the near future. The report argues that while the EU’s image has suffered greatly from the sovereign debt crisis and the way it has been handled, there is room to improve China’s view of Europe and for the EU to maintain a relatively strong negotiation position towards China.

Individual differences in the effects of perceived controllability on pain perception: critical role of the prefrontal cortex

The degree to which perceived controllability alters the way a stressor is experienced varies greatly among individuals. We used functional magnetic resonance imaging to examine the neural activation associated with individual differences in the impact of perceived controllability on self-reported pain perception. Subjects with greater activation in response to uncontrollable (UC) rather than controllable (C) pain in the pregenual anterior cingulate cortex (pACC), periaqueductal gray (PAG), and posterior insula/SII reported higher levels of pain during the UC versus C conditions. Conversely, subjects with greater activation in the ventral lateral prefrontal cortex (VLPFC) in anticipation of pain in the UC versus C conditions reported less pain in response to UC versus C pain. Activation in the VLPFC was significantly correlated with the acceptance and denial subscales of the COPE inventory [Carver, C. S., Scheier, M. F., & Weintraub, J. K. Assessing coping strategies: A theoretically based approach. Journal of Personality and Social Psychology, 56, 267–283, 1989], supporting the interpretation that this anticipatory activation was associated with an attempt to cope with the emotional impact of uncontrollable pain. A regression model containing the two prefrontal clusters (VLPFC and pACC) predicted 64% of the variance in pain rating difference, with activation in the two additional regions (PAG and insula/SII) predicting almost no additional variance. In addition to supporting the conclusion that the impact of perceived controllability on pain perception varies highly between individuals, these findings suggest that these effects are primarily top-down, driven by processes in regions of the prefrontal cortex previously associated with cognitive modulation of pain and emotion regulation.

Individual Differences in Amygdala and Ventromedial Prefrontal Cortex Activity are Associated with Evaluation Speed and Psychological Well-being

Using functional magnetic resonance imaging, we examined whether individual differences in amygdala activation in response to negative relative to neutral information are related to differences in the speed with which such information is evaluated, the extent to which such differences are associated with medial prefrontal cortex function, and their relationship with measures of trait anxiety and psychological well-being (PWB). Results indicated that faster judgments of negative relative to neutral information were associated with increased left and right amygdala activation. In the prefrontal cortex, faster judgment time was associated with relative decreased activation in a cluster in the ventral anterior cingulate cortex (ACC, BA 24). Furthermore, people who were slower to evaluate negative versus neutral information reported higher PWB. Importantly, higher PWB was strongly associated with increased activation in the ventral ACC for negative relative to neutral information. Individual differences in trait anxiety did not predict variation in judgment time or in amygdala or ventral ACC activity. These findings suggest that people high in PWB effectively recruit the ventral ACC when confronted with potentially aversive stimuli, manifest reduced activity in subcortical regions such as the amygdala, and appraise such information as less salient as reflected in slower evaluative speed.
