RESUM L'automatització s'utilitza des de fa molts anys, tot i que va començar a agafar la definició que coneixem actualment al voltant dels anys seixanta i setanta, moment en què es comencen a comercialitzar els primers PLC. A partir d'aquí, el seu creixement ha estat exponencial. En aquest sentit, la tecnologia ha anat avançant i ha augmentat els components que la forma, per això a hores d'ara encara no sabem fins on podrà arribar i què aconseguirà. Per a la indústria tot això ha significat l'automatització de processos que fins ara utilitzaven molt mà d'obra, reduint-la dràsticament. Una de les indústries que més s'ha beneficiat de tots aquests avenços ha estat la de l'automoció, concretament les seves grans línies de producció, automatitzades a uns nivells que fins fa poc temps eren impensables. Aquest projecte forma part d'aquesta indústria, no directament per a la construcció de l'automòbil, sinó indirectament, ja que l'empresa per a la qual s'ha fet l'automatització fabrica peces plàstiques per a automòbils. Concretament, unes peces amb uns injerts metàl•lics conductors que es munten a tots els vehicles i s'utilitzen per accionar els neteja vidres dels cotxes. Aquest fet implica que la fabricació i el disseny de la peça sigui curosament vigilat i controlat per al client final, amb uns controls de qualitat extremadament exigents. El funcionament del procés de fabricació es fa a partir d'unes peces de plàstic produïdes per una injectora que es fan passar per unes estacions automatitzades, cada una de les quals fa una acció concreta per aconseguir el muntatge final.

It has been claimed that extreme black holes exhibit a phenomenon of flux expulsion for Abelian Higgs vortices, irrespective of the relative width of the vortex to the black hole. Recent work by two of the authors showed a subtlety in the treatment of the event horizon, which cast doubt on this claim. We analyze in detail the vortexextreme black hole system, showing that, while flux expulsion can occur, it does not do so in all cases. We give analytic proofs for both expulsion and penetration of flux, in each case deriving a bound for that behavior. We also present extensive numerical work backing up, and refining, these claims, and showing in detail how a vortex can end on a black hole in all situations. We also calculate the back reaction of the vortex on the geometry, and comment on the more general vortexblack hole system.

Objective: Integration of the radiotherapy technologist "know-how" in the Gamma Knife treatment processMaterials and Methods: Gamma Knife (GK) treatments started in July 2010 at the GK Center in C.H.U.V. with the Leksell Gamma KnifeR Perfexion?(Elekta AB, Sweden). The multidisciplinary GK team involves neurosurgeons, radio-oncologists, physicists, neuroradiologists, nurses and technologists, aiming at a full integration for optimal patient management.Results: Between July and December 2010, 60 patients have been treated. Required stereotactic imaging involves IRM, CT scan (and angiography for AVM). All the steps in the treatment process (Leksell coordinate frame fixation, imaging, planning, treatment) are supervised by the members of the multidisciplinary team. In our experience, radiotherapy technologist (RTT) have acquired an important role in the multidisciplinary team communication and integration. Specifically, the RTT are responsible of: supervision of the image acquisition, performing the Gamma Knife unit control tests, patient setup, and patient surveillance during treatment.Conclusion: RTT have a fundamental role in the communication within the team, between the team and the patient and also to assure the patient security. Our experience shows that it is possible and required to involve RTT in all steps of the GK treatment process, to guarantee the best GK treatment possible.

Aquest és un projecte d'investigació descriptiva. Té com a finalitat conèixer i comprendre com és la inclusió dels nens amb Paràlisis Cerebral a les escoles ordinàries (bressol, primària i secundària), de la ciutat de Barcelona, des de la mirada de la Teràpia Ocupacional. Per tant, primer s'ha d'investigar quants alumnes amb aquesta lesió estan inclosos en escoles ordinàries, com també conèixer quants alumnes tornen a l'escola especial després d'estar escolaritzats a la ordinària. D'altra banda, es pretén descriure les perspectives i percepcions dels professionals i els alumnes implicats a la inclusió, i què succeeix a l'escola ordinària perquè alguns alumnes hagin de tornar a l'especial en algun moment de la seva escolarització. El projecte és de caire qualitatiu, on els instruments per l'obtenció de dades són protocols d'observació, entrevistes semi- estructurades i enquestes. Encara que per obtenir la mostra i els participants s'utilitzaran tècniques quantitatives. Les limitacions de l'estudi seran aquelles escoles, professionals i alumnes que per motius personals no vulguin participar de la mostra.

La principal idea que es planteja en el present Treball Final de Grau és conèixer com s’intervé en una aula amb un infant que pot presentar algun Trastorn Generalitzat del Desenvolupament (TGD). Concretament, a través de l’anàlisi d’un cas, on la hipòtesi diagnòstica actual és un retard cognitiu lleu, ja que no mostra un diagnòstic clar. No obstant, aquesta intervenció s’adequarà als símptomes i característiques de cada infant. Per tal de contemplar el desenvolupament de l’infant, s’han dut a terme diverses activitats referents a l’aprenentatge cooperatiu que han ajudat ha observar la interacció del nen amb els altres infants.

Recent studies indicate that Neanderthal and Denisova hominins may have been separate species, while debate continues on the status of Homo floresiensis. The decade-long debate between "splitters," who recognize over 20 hominin species, and "lumpers," who maintain that all these fossils belong to just a few lineages, illustrates that we do not know how many extinct hominin species to expect. Here, we present probability distributions for the number of speciation events and the number of contemporary species along a branch of a phylogeny. With estimates of hominin speciation and extincton rates, we then show that the expected total number of extinct hominin species is 8, but may be as high as 27. We also show that it is highly unlikely that three very recent species disappeared due to natural, background extinction. This may indicate that human-like remains are too easily considered distinct species. Otherwise, the evidence suggesting that Neanderthal and the Denisova hominin represent distinct species implies a recent wave of extinctions, ostensibly driven by the only survivor, H. sapiens.

Introduction : Doublecortin (DCX) is a microtubule associated protein expressed by migrating neural precursors. DCX is also expressed in approximately 4% of all cortical cells in adult normal primate brain. DCX expression is also enhanced locally in response to an acute insult made to the brain. This is thought to play a role in plasticity or neural repair. That being said, it would be interesting to know how the expression of DCX is modified in a more chronic insult, like in neurodegeneration such as in Parkinson's Disease (PD) and Alzheimer's Disease (AD). The aim of my study is to study the expression of DCX cells in the cortex of patients having a neurodegenerative disease, compared to control patients. Method: DCX cells quantification on 9 DCX‐stained 5 μm thick formalin fixed paraffin embedded brain sections: 3 Alzheimer's disease patients, 3 Parkinson's disease patients and 3 control patients. Each patient had several sections that we could stain with different stainings (GALLYA, TAU, DCX). By using a computerized image analysis system (Explora Nova, La Rochelle, France), cortical columns were selected on areas on the cortex with a lot of degeneration subjectively observed on GALLYA stained sections and on TAU stained sections. Then total number of cells was counted on TAU sections, where all nuclei were colored in blue. Then the DCX cells were counted on the corresponding DCX sections. These values were standardized to a reference surface area. The ratio of DCX cells over total cells was then calculated. Results : There is a difference of DCX cell expression between Alzheimer's Disease patients and control patients. The percentage of dcx cells in the cortex of an Alzheimer's patient is around 12.54% ± 2.17%, where as in the cortex of control patients, it is around 5.47% ± 0.83%. On the other hand, there is no significant difference in the ratio of DCX cells over total cells between parkinson's patients and control patients, both having around 5% of DCX cells. Discussion: There is a dramatic increase of DCX expression in AD (12.5%) compared to PD and controls (5.5%). The increase in DCX ratio in AD may have two potential causes: 1.The increased ratio is due to DCX cells being more resistant to degeneration compared to surrounding cells which are degenerating due to AD, leading to the cortical atrophy observed in AD patients. So the decrease of total cells without any change in the number of DCX cells makes the ratio bigger in AD compared to the controls. 2.The increased ratio is due to an actual increase in DCX cells. This means that there is some neural repair to compensate the degenerative process, just like the repair process observed in acute lesions to the brain. This second idea can be integrated in the broader point of view of neuroinflammation. The progression of the disease would trigger neuroinflammation and the process following the primary inflammatory response which is neural repair. So our study can show that the increase in DCX cells is an attempt to repair the degenerated neurons, in the context of neuroinflammation triggered by the physiopathological progression of the disease.

The Universitat Oberta de Catalunya (Open University of Catalonia, UOC) is an online university that makes extensive use of information and communication technologies to provide education. Ever since its establishment in 1995, the UOC has developed and tested methodologies and technological support services to meet the educational challenges posed by its student community and its teaching and management staff. The know-how it has acquired in doing so is the basis on which it has created the Open Apps platform, which is designed to provide access to open source technical applications, information on successful learning and teaching experiences, resources and other solutions, all in a single environment. Open Apps is an open, online catalogue, the content of which is available to all students for learning purposes, all IT professionals for downloading and all teachers for reusing.To contribute to the transfer of knowledge, experience and technology, each of the platform¿s apps comes with full documentation, plus information on cases in which it has been used and related tools. It is hoped that such transfer will lead to the growth of an external partner network, and that this, in turn, will result in improvements to the applications and teaching/learning practices, and in greater scope for collaboration.Open Apps is a strategic project that has arisen from the UOC's commitment to the open access movement and to giving knowledge and technology back to society, as well as its firm belief that sustainability depends on communities of interest.
