En els darrers anys, els sistemes de telemetria per a aplicacions mèdiques han crescut significativament en el diagnòstic i en la monitorització de, per exemple, la glucosa, la pressió de la sang, la temperatura, el ritme cardíac... Els dispositius implantats amplien les aplicacions en medicina i incorpora una millora de qualitat de vida per a l’usuari. Per aquest motiu, en aquest projecte s’estudien dues de les antenes més comuns, com son l’antena dipol i el patch, aquesta última és especialment utilitzada en aplicacions implantades. En l’anàlisi d’aquestes antenes s’han parametritzat característiques relacionades amb l’entorn de l’aplicació, així com també de la pròpia antena, explicant el comportament que, a diferencia amb l’espai lliure, les antenes presenten a canvis d’aquests paràmetres. Al mateix temps, s’ha implementat una configuració per a la mesura d’antenes implantades basat en el model del cos humà d’una capa. Comparant amb els resultats de les simulacions realitzades mitjançant el software FEKO, s’ha obtingut gran correspondència en la mesura empírica d’adaptació i de guany de les antenes microstrip. Gràcies a l’anàlisi paramètric, aquest projecte també presenta diversos dissenys de les antenes optimitzant el guany realitzable amb l’objectiu d’aconseguir la millor comunicació possible amb el dispositiu extern o estació base.

In this article we present the first empirical analysis on the associations between body size, activity, employment and wages for several European countries. The main advantage of the present work with respect to the previous literature is offered by the comparability of the data and its large geographical coverage. According to our results, for Spanish women, being obese is associated with both a 9% lower wage and probability of being employed, while for Swedish and Danish, obesity is associated with a 12% lower probability of being employed, and a 10% lower wage respectively. In Belgium, obesity is associated with a 19% lower probability of being employed for men. These robust estimates are strongly informative and may be used as a simple statistical rule of thumb to decide the countries in which lab and field experiments should be run.

A model of directed search with a finite number of buyers and sellers is considered, where sellers compete in direct mechanisms. Buyer heterogeneity and Nash equilibrium results in perfect sorting. The restriction to complementary inputs, that the match value function Q is supermodular, in addition coordinates the sellers strategies. In that case, equilibrium implements positive assortative matching, which is efficient and consistent with the stable (cooperative equilibrium) outcome. This provides a non-cooperative and decentralizedsolution for the Assignment Game. Conversely, if buyers are identical, no such coordination is possible, and there is a continuum of equilibria, one of which exhibits price posting, another yields competition in auctions.

This paper studies a balance whose unobservable fulcrum is not necessarilylocated at the middle of its two pans. It presents three differentmodels, showing how this lack of symmetry modifies the observation, theformalism and the interpretation of such a biased measuring device. Itargues that the biased balance can be an interesting source of inspirationfor broadening the representational theory of measurement.

This paper examines the associations between obesity, employment status and wages for several European countries. Our results provide weak evidence that obese workers are more likely to be unemployed or tend to be more segregated in self-employment jobs than their non-obese counterparts. We also find difficult to detect statistically significant relationships between obesity and wages. As previously reported in the literature, the association between obesity, unemployment and wages seems to be different for men and women. Moreover, heterogeneity is also found across countries. Such heterogeneity can be somewhat explained by some labor market institutions, such as the collective bargaining coverage and the employer-provided health insurance.

The problem of obesity is alarming public health authorities around the world. Therefore, it is important to study its determinants. In this paper we explore the empirical relationship between household income and body mass index (BMI) in nine European Union countries. Our findings suggest that the association is negative for women, but we find no statistically significant relationship for men. However, we show that the different relationship for men and women appears to be driven by the negative relationship for women between BMI and individual income from work. We tentatively conclude that the negative relationship between household income and BMI for women may simply be capturing the wage penalty that obese women suffer in the labor market.

Avui, a la Catalunya Nord, més de quatre-cents alumnes, de dos a quinze anys, van cada dia a una escola on la llengua habitualment és el català: als patis, a les aules, en la relació amb els mestres. Se senten verbs rossellonins, «jo vingui», "jo arribi"... Als del Principat ens resulta una mica sorprenent llegir la paraula bourrou escrit en «francès» amb lletra dubtosa, d'aprenent molt jove. És el resultat de la tossuderia, la fe i ta feina de La Bressola. De moment, el seu anar fent pausat i continu ha obert set escoles de primària i, fa poc, ha iniciat el trajecte de la secundària. Si hem de fer cas de la demanda social, l'oferta es queda curta: més de seixanta peticions d'escolarització no s'han pogut atendre enguany, per manca d'infraestructura, no pas de voluntat

L’objectiu d’aquest projecte és el de dissenyar un comprovador semiautomàtic per a un model d’automatisme que controla l’obertura i el tancament d’una porta. Aquest automatisme requereix d’una verificació de qualitat abans de ser introduït al mercat. La seva comprovació manual és lenta. L’objectiu principal del comprovador, és el de reduir aquest temps de test en almenys un 50% i fer més fàcil la detecció dels errors. El comprovador consta d’un suport per a l’automatisme que transmet els seus punts crítics a una placa de control. Conté un microcontrolador PIC16F887 que gestiona totes les entrades i sortides provinents de l’automatisme. També controla una pantalla LCD de 16x2 caràcters, que mostra els passos a seguir del test i si hi ha algun error. Es fa el disseny d’aquesta placa des de el hardware fins al software. Els resultats del projecte són satisfactoris, ja que compleix els objectius marcats i és un sistema que s’utilitza en l’empresa on es fabriquen aquests automatismes de control de portes.

The aim of this study is to determine the profile of dependent elderly people users of the home care services (SAD) of the regional council in Osona (Consell Comarcal d´Osona) , and the characteristics of formal and informal types of support they use. Methodology. An observational study of a transversal format has been carried out, with retrospective and descriptive purposes. The target population is 63 people (26 men and 37 women) included in the program of the regional SAD They have a recognized dependence grade approved by the law 39 /2006, December 14th , promoting the individual autonomy and care of elderly people in a dependent situation. The data were collected by social workers of basic social services, first with a home visit and followed by handed out questionnaires, specifically designed for this study, in order to obtain information on socio-demographic characteristics, and the type of support formal and informal. The obtained results on the SAD users are women in a 58.7% and a 41.3 % are men. The 84% of the total sampling are 80 years old and more, being the average age of 85.2 years old. 45% of them are married, 41% are widows and widowers and 14% are single. 54% are rated with severe dependence (grade II), 42.8% with high dependence (grade III). 86% live accompanied. 100% have an informal caregiver and a 95% of the times, the caregiver is a relative who in 73% of the cases the dedication time is permanent. The coverage of the SAD has an average of 4.27 hours per week and per user. The formal services most used are the technical (62%), also the assessment of an occupational therapist at home (57%) and the telecare service in a (56%). Conclusions. The SAD is used primarily for women in an advanced age and severe dependence. The informal assistance structures have an informal caregiver, being a member of the family mostly, living with the dependent, and mainly in a permanent dedication basis. The SAD has a varied intensity in each case. The formal support services complementary to the SAD, are largely used in all cases.

We have reported in a variety of mammalian cells the reversible formation of a filamentous actin (F-actin)-enriched aggresome generated by the actin toxin jasplakinolide (Lázaro-Diéguez et al., J Cell Sci 2008; 121:1415-25). Notably, this F-actin aggresome (FAG) resembles in many aspects the pathological Hirano body, which frequently appears in some diseases such as Alzheimer's and alcoholism. Using selective inhibitors, we examined the molecular and subcellular mechanisms that participate in the clearance of the FAG. Chaperones, microtubules, proteasomes and autophagosomes all actively participate to eliminate the FAG. Here we compile and compare these results and discuss the involvement of each process. Because of its simplicity and high reproducibility, our cellular model could help to test pharmacological agents designed to interfere with the mechanisms involved in the clearance of intracellular bodies and, in particular, of those enriched in F-actin.

Caveolins are a crucial component of caveolae but have also been localized to the Golgi complex, and, under some experimental conditions, to lipid bodies (LBs). The physiological relevance and dynamics of LB association remain unclear. We now show that endogenous caveolin-1 and caveolin-2 redistribute to LBs in lipid loaded A431 and FRT cells. Association with LBs is regulated and reversible; removal of fatty acids causes caveolin to rapidly leave the lipid body. We also show by subcellular fractionation, light and electron microscopy that during the first hours of liver regeneration, caveolins show a dramatic redistribution from the cell surface to the newly formed LBs. At later stages of the regeneration process (when LBs are still abundant), the levels of caveolins in LBs decrease dramatically. As a model system to study association of caveolins with LBs we have used brefeldin A (BFA). BFA causes rapid redistribution of endogenous caveolins to LBs and this association was reversed upon BFA washout. Finally, we have used a dominant negative LB-associated caveolin mutant (cavDGV) to study LB formation and to examine its effect on LB function. We now show that the cavDGV mutant inhibits microtubule-dependent LB motility and blocks the reversal of lipid accumulation in LBs.
