Producció de material docent per a ciència de materials mitjançant microscòpia electrònica de rastreig i làser confocal

Aquest projecte s'ha realitzat al Servei de Microscòpia de la Universitat Autònoma de Barcelona, i ha tingut una durada de dos anys (2006-2008). La finalitat d’aquest projecte ha estat l’elaboració de material didàctic basat en la captació d’imatges i l’edició de recursos pedagògics de suport digital aplicats a la ciència de materials. Es pretén millorar així la qualitat docent de les pràctiques de diverses assignatures dels ensenyaments de Física i d’Enginyeria de Materials utilitzant tècniques d’anàlisi actuals com són la Microscòpia Electrònica de Rastreig (MER) i la Microscòpia Optica (MO). Amb aquest projecte es vol fomentar també el treball interdisciplinari en equip entre professionals (docents i tècnics superiors de recerca) i acostar la teoria de les assignatures a la realització pràctica, facilitant el suport digital necessari per aconseguir un màxim aprofitament a les aules. Les imatges de MER i MO ajudaran als alumnes a familiaritzar-se amb el món de la recerca i la indústria.

Creació de material docent digital per l'assignatura transversal de Geoarqueologia

En aquest projecte hem seguit desenvolupant i ampliant els continguts d’una assignatura de caràcter transversal entre Geologia i Arqueologia Prehistòrica aplicada als estudis universitaris. Aquesta ampliació s’ha dut a terme amb la creació d'un recull de fitxes amb les dades més rellevants d’alguns sepulcres megalítics de Catalunya fent especial esment als materials petris utilitzats en la seva construcció de per tal de poder desenvolupar i contextualitzar els resultats que s’assoleixin durant el curs. Cadascuna de les fitxes inclou per cada megàlit: 1) una situació geogràfica, 2) una part de descripció des del punt de vista arqueològic i 3) una part geològica amb la situació, descripció dels elements petris de les lloses tant a visu com al microscopi petrogràfic i una localització probable de l’àrea de procedència de les lloses. Això suposa un aprofundiment i ampliació de l'oferta pedagògica proposada que permet experimentar una metodologia d’ensenyament universitari més pràctica, aplicada i interactiva i s’emmarca en l’eix temàtic al voltant del qual es desenvolupa l’assignatura.

La définition des interfaces pour améliorer la qualité: l'exemple de l'anorexie en hospitalisation somatique [Defining interfaces to improve quality of care: the example of anorexia nervosa in acute somatic hospitalisation]

Specialisation in medicine requires multidisciplinary approaches, and hence coordination in collaborations of the different partners involved. These integrated approaches, sometimes called "disease management", fit particularly well to chronic diseases. Our institution introduced an integrated approach for taking care of the acute somatic hospitalisation of patients suffering from anorexia nervosa. Interfaces with the different partners were defined, specifying tasks, rights, and duties of each person, care givers or patients. This initiative allows now to identify any deviation occurring in the process of care or hole in the care system, so that it can be corrected and recurrence prevented. This model will be extended to other complex and multidisciplinary care processes and other services in our institution.

Contact melting of a three-dimensional phase change material on a flat substrate

In this paper a model is developed to describe the three dimensional contact melting process of a cuboid on a heated surface. The mathematical description involves two heat equations (one in the solid and one in the melt), the Navier-Stokes equations for the flow in the melt, a Stefan condition at the phase change interface and a force balance between the weight of the solid and the countering pressure in the melt. In the solid an optimised heat balance integral method is used to approximate the temperature. In the liquid the small aspect ratio allows the Navier-Stokes and heat equations to be simplified considerably so that the liquid pressure may be determined using an igenfunction expansion and finally the problem is reduced to solving three first order ordinary differential equations. Results are presented showing the evolution of the melting process. Further reductions to the system are made to provide simple guidelines concerning the process. Comparison of the solutions with experimental data on the melting of n-octadecane shows excellent agreement.

Information Mobility: Information Dissemination in Mobile Networks

En el nostre projecte, considerem un escenari urbà o interurbà on persones amb dispositius mòbils (smartphones) o vehicles equipats amb interfícies de comunicació, estan interessats en compartir fitxers entre ells o descarregar-los al creuar Punts d’Accés (APs) propers a la carretera. Estudiem la possibilitat d’utilizar la cooperació en les trobades casuals entre nodes per augmentar la velocitat de descàrrega global. Amb aquest objectiu, plantejem algoritmes per a la selecció de quins paquets, per a quins destins i quins transportistes s’escullen en cada moment. Mitjançant extenses simulacions, mostrem com les cooperacions carry&forward dels nodes augmenten significativament la velocitat de descàrrega dels usuaris, i com aquest resultat es manté per a diversos patrons de mobilitat, col•locacions d'AP i càrregues de la xarxa. Per altra banda, aparells com els smartphones, on la targeta de WiFi està encesa contínuament, consumeixen l'energia de la bateria en poques hores. En molts escenaris, una targeta WiFi sempre activa és poc útil, perque sovint no hi ha necessitat de transmissió o recepció. Aquest fet es veu agreujat en les Delay Tolerant Networks (DTN), on els nodes intercanvien dades quan es creuen i en tenen l’oportunitat. Les tècniques de gestió de l’estalvi d’energia permeten extendre la duració de les bateries. El nostre projecte analitza els avantatges i inconvenients que apareixen quan els nodes apaguen períodicament la seva targeta wireless per a estalviar energia en escenaris DTN. Els nostres resultats mostren les condicions en que un node pot desconnectar la bateria sense afectar la probabilitat de contacte amb altres nodes, i les condicions en que aquesta disminueix. Per exemple, es demostra que la vida del node pot ser duplicada mantenint la probabilitat de contacte a 1. I que aquesta disminueix ràpidament en intentar augmentar més la vida útil.

La necesidad surge con la aplicación mlcoalsim, utilizada por investigadores de la UAB, cuya parametrización requiere la edición manual de un fichero de texto la sintaxis del cual es complicada y pesada. Con la generación de interfaces web se pretende ayudar a los usuarios en la correcta parametrización y ejecución de aplicaciones como mlcoalsim.

The InterPro Database, 2003 brings increased coverage and new features.

InterPro, an integrated documentation resource of protein families, domains and functional sites, was created in 1999 as a means of amalgamating the major protein signature databases into one comprehensive resource. PROSITE, Pfam, PRINTS, ProDom, SMART and TIGRFAMs have been manually integrated and curated and are available in InterPro for text- and sequence-based searching. The results are provided in a single format that rationalises the results that would be obtained by searching the member databases individually. The latest release of InterPro contains 5629 entries describing 4280 families, 1239 domains, 95 repeats and 15 post-translational modifications. Currently, the combined signatures in InterPro cover more than 74% of all proteins in SWISS-PROT and TrEMBL, an increase of nearly 15% since the inception of InterPro. New features of the database include improved searching capabilities and enhanced graphical user interfaces for visualisation of the data. The database is available via a webserver (http://www.ebi.ac.uk/interpro) and anonymous FTP (ftp://ftp.ebi.ac.uk/pub/databases/interpro).

PHA urges 'freshers' to be smart and know their alcohol limits

As 'fresher's week' commences, the Public Health Agency is encouraging students across Northern Ireland to avoid binge drinking and to know their limits if they do choose to drink alcohol.Enjoying new freedoms, at college or university, means taking care of yourself and others and, if you choose to drink, staying within safe alcohol limits. Owen O'Neill, PHA Health and Social Wellbeing Improvement Manager for drugs and alcohol, said: "Some young people may drink more when they leave home, or join their friends in college or university for the first time. They might think that, as young people, they don't have to take care with alcohol, but staying within the safe drinking limits is important for everyone who drinks. Excessive and binge drinking can have lasting effects on health, such as damage to the liver, heart, brain and stomach. Drinking too much can also increase the risk of accidents and antisocial behaviour as well as sexually transmitted infections and unplanned pregnancy"."We would also strongly advise against drinking games. Although they are regarded as a 'bit of fun', in reality they can be very dangerous. As an extreme form of binge drinking, where large quantities of alcohol are consumed in a very short time, drinking games can result in alcohol poisoning, leading to brain damage, coma or death. The PHA encourages students to enjoy their new student life, but urges them to be aware of their alcohol intake and drink responsibly, especially throughout fresher's week, with the many cheap drink promotions currently available."Daily alcohol limits are recommended by the government in order to avoid the risks of excessive and binge drinking in any one session. These are:Men: No more than 3 to 4 units of alcohol a day and no more than 21 units over the course of the week.Women: No more than 2 to 3 units of alcohol a day and no more than 14 units over the course of the week.Examples of units:Can of extra strong lager - 4 unitsBottle of lager - 1.5 unitsPint of standard lager - 2.5 unitsPint of premium larger - 3 unitsSmall pub bottle of wine - 2.25 units70cl bottle of wine - 7 to 10 unitsStandard 275ml of alcopops - 1.5 to 1.8 units70cl bottle of alcopops - 3.75 to 4.5 unitsPub measure of spirits - 1.5 unitsPint of cider - 3 unitsPint of stout - 2.5 unitsIf you do choose to drink alcohol:DON'T:Ever drink and driveDrink on an empty stomachMix alcohol with other drugsDrink in rounds as this may speed up your drinkingLeave your drinks unattendedDO:Take sips rather than gulpsAlternate each alcoholic drink with a non alcoholic drink e.g. water or a soft drinkSet yourself a limit and try to stick to it (refer to daily alcohol limits) Take frequent breaks from drinking to give your body time to recoverTell friends and family where you are going and who you will be withRemember, that for each unit you drink over the daily limit, the risk to your health increases. It's important to spread the units throughout the week - you can't 'save up' your units for the weekend or your holiday. It is also important to drink plenty of water, ideally matching the amount of alcohol you have consumed.So students make smart choices this term - drink sensibly and know your limits!For further information on sensible drinking and alcohol units visit the Public Health Agency's website www.knowyourlimits.info

A New Year's Resolution - be smart about your drinking!

Now 2012 has arrived, the Public Health Agency is encouraging people to make a New Year's resolution to know their limits when it comes to alcohol, not to drink excessively and to cut back for a while, especially if the festive period led to a little too much consumption.Owen O'Neill, PHA Health and Social Wellbeing Improvement Manager and drugs and alcohol lead, explained: "The New Year is a great opportunity for us to be positive about our health, making resolutions that make us look and feel better. If people choose to drink, staying within the safe drinking limits is important. Excessive and binge drinking can have lasting effects on health, such as damage to the liver, heart, brain and stomach. Drinking too much can also increase the risk of accidents and antisocial behaviour as well as sexually transmitted infections and unplanned pregnancy. And it doesn't have to be drinking to extremes - regularly drinking over the recommended limits can have a damaging effect."Remember that for each unit you drink over the daily limit, the risk to your health increases. It's important to spread the units throughout the week and not 'save' them for the weekend and to drink plenty of water, ideally matching the amount of alcohol you have consumed."For those who have consumed a lot of alcohol over the festive season, cutting back in the New Year and being careful can have immediate, positive effects particularly on helping you to look and feel better, being less tired during the day, feeling fitter and perhaps losing weight. Longer term, the benefits include improved mood, sleep, memory and general health, particularly improving liver function, immunity to illness and preventing any damage caused by any excessive drinking getting any worse."Daily alcohol limits are recommended by the government to avoid the dangers of excessive and binge drinking in any one session. These are:MenNo more than 3 to 4 units of alcohol a day and no more than 21 units over the course of the week.WomenNo more than 2 to 3 units of alcohol a day and no more than 14 units over the course of the week.Examples of units:Can of extra strong lager - 4 unitsBottle of lager - 1.5 unitsSmall pub bottle of wine - 2.25 unitsPub measure of spirits - 1.5 unitsPint of stout - 2.5 unitsPint of cider - 3 unitsFor further information on sensible drinking and alcohol units visit the Public Health Agency's website www.knowyourlimits.info
