CATapia : la arquitectura de tapia en Cataluña. Conocimiento, reivindicación y restauración

Este trabajo tiene dos objetivos principales. El primero es identificar, catalogar y estudiar la arquitectura de tapia en Cataluña. A través de este estudio se pretende mejorar el conocimiento de este sistema constructivo milenario, con el fin de reivindicar esta técnica y su presencia en Cataluña. El segundo objetivo es el estudio de la conservación, restauración e intervención de la tapia en esta comunidad, analizando los criterios de intervención empleados y su compatibilidad con la técnica constructiva.Ortiz Campañá, M.

Oxfendazole flukicidal activity in pigs

Although oxfendazole (OFZ) is a well know broad-spectrum benzimidazole anthelmintic, the assessment of its potential trematodicidal activity remains unexplored. OFZ administration at single high doses has been recommended to control Taenia solium cysticercus in pigs. The current study investigated the flukicidal activity obtained after a single high (30 mg/kg) oral dose of OFZ in pigs harbouring a natural Fasciola hepatica infection. Sixteen (16) local ecotype pigs were randomly allocated into two (2) experimental groups of 8 animals each named as follow: Untreated control and OFZ treated, in which animals received OFZ (Synanthic®, Merial Ltd., 9.06% suspension) orally at 30 mg/kg. At seven (7) days post-treatment, all the animals were sacrificed and direct adult liver fluke counts were performed following the WAAVP guidelines. None of the animals involved in this experiment showed any adverse event during the study. OFZ treatment as a single 30 mg/kg oral dose showed a 100% efficacy against F. hepatica. In conclusion, the trial described here demonstrated an excellent OFZ activity against F. hepatica in naturally infected pigs, after its administration at a single oral dose of 30 mg/kg.Fil: Ortiz, Pedro.

Improving transversal competences by using wikis in collaborative work

Work on transversal competences in university degrees is a teaching line entirely established since the implementation of the European Credit Transfer System (ECTS). Nevertheless, undergraduate students present shortcomings in the development of some of these competences, especially on collaborative work, time management, oral and writing expression, and on the use of information resources. This paper presents a virtual tool and associated guidelines to enhance the information management during the development of collaborative works, and to facilitate the information availability among the students. Moreover, this tool and the guideline improve the individual monitoring and evaluation of the contributions of the students to the work. The proposal presented in this work belongs to a teaching innovation project carried out in the Earth Sciences Faculty of the Universitat de Barcelona, and implemented in the subjects General Geology (first-year in the Engineering Geology degree, 6 ECTS) and Geochemistry (third-year course in the Geology degree, 9 ECTS)Peer Reviewe

Creació d'una Eina de suport per a la docència en Geoquímica. Una eina d'aprenentatge autònom i d'avaluació

La proposta presentada s'emmarca en un projecte d'innovació docent de la Universitat de Barcelona. L'objectiu és desenvolupar una nova eina interactiva que d'una banda ajudi els alumnes a reforçar i/o ampliar els coneixements de geoquímica de manera autònoma i, de l'altra, sigui un nou recurs d'avaluació per al professorat. Amb el desenvolupament d'aquest eina, l'alumnat disposarà d'un recurs didàctic que li permetrà madurar i ampliar el seus coneixements en el camp de la geoquímica

Millora de competències transversals mitjançant el treball col·laboratiu amb wikis

L'aplicació de wikis en el desenvolupament de treballs col·laboratius és una eina virtual que millora la gestió de la informació científica que es recull i en facilitat la disponibilitat a tots els membres del grup. Aquesta eina, a més, millora el seguiment i avaluació del treball i de les contribucions de cada membre del grup per part del professorat. En aquest treball es presenten els resultats d'aquesta l'experiència docent en dues assignatures molt diferenciades

Two different strategies to enhance osseointegration in porous titanium: Inorganic thermo-chemical treatment versus organic coating by peptide adsorption

In this study, highly-interconnected porous titanium implants were produced by powder sintering with different porous diameters and open interconnectivity. The actual foams were produced using high cost technologies: Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), and spark plasma sintering, and the porosity and/or interconnection was not optimized. The aim was to generate a bioactive surface on foams using two different strategies, based on inorganic thermo-chemical treatment and organic coating by peptide adsorption, to enhance osseointegration. Porosity was produced using NaCl as a space holder and polyethyleneglicol as a binder phase. Static and fatigue tests were performed in order to determine mechanical behaviors. Surface bioactivation was performed using a thermo-chemical treatment or by chemical adsorption with peptides. Osteoblast-like cells were cultured and cytotoxicity was measured. Bioactivated scaffolds and a control were implanted in the tibiae of rabbits. Histomorphometric evaluation was performed at 4 weeks after implantation. Interconnected porosity was 53% with an average diameter of 210 µm and an elastic modulus of around 1 GPa with good mechanical properties. The samples presented cell survival values close to 100% of viability. Newly formed bone was observed inside macropores, through interconnected porosity, and on the implant surface. Successful bone colonization of inner structure (40%) suggested good osteoconductive capability of the implant. Bioactivated foams showed better results than non-treated ones, suggesting both bioactivation strategies induce osteointegration capability.Postprint (published version

The UALE project : a cross-sectional approach for trends in HIV/STI prevalence among key populations attending STI clinics in Guatemala

To describe and compare trends in prevalence, sexual behaviour and HIV transmission knowledge data related to sexually transmitted infections (STI) and HIV in patients attending three STI clinics over an 8-year period in Escuintla Department, Guatemala. STI clinic attendees were classified into transmission groups as follows: female sex workers (FSW), men who have sex with men (MSM) and 'high-risk heterosexuals' (HRH). Annual cross-sectional analysis and multivariable Poisson regression adjusted for sociodemographic variables were used for prevalence comparisons and adjusted prevalence trends for HIV/STI outcomes and used for adjusted trends in proportions in sexual behaviour and HIV transmission knowledge outcomes. Endocervical swabs were obtained to detect trichomonas, chlamydia and neisseria infections. Serologies for syphilis and HIV were performed using rapid tests. For reactive HIV samples, positivity was confirmed by an ELISA. All reactive syphilis samples were further confirmed for diagnosis of active syphilis disease. From a total of 4027 clinic attendees, 3213 (79.78%) were FSW, 229 (5.69%) were MSM and 585 (14.53%) were HRH. The proportion of FSW, MSM and HRH who had a single visit was 56.42%, 57.23% and 91.10%, respectively. Overall, HIV prevalence was 2.10% in FSW, 8.17% in MSM and 4.12% in HRH. Prevalence trends in HIV and syphilis decreased in FSW. Prevalence trends in gonorrhoea did not decrease over time neither in FSW nor in HRH. Chlamydia and trichomonas infections in HRH showed an increase prevalence trend. In FSW, trends in condom use in last sexual intercourse with regular and occasional clients were above 93%. FSW show a decreasing trend in HIV, syphilis and chlamydia prevalence. Gonorrhoea prevalence in FSW and HRH did not decrease over time. HRH is a hard to engage population with low follow-up rates and high potential to act as a bridge population
