Sixty-nine entire male pigs with different halothane genotype (homozygous halothane positive – nn-, n=36; and homozygous halothane negative – NN-, n=33) were fed with a supplementation of magnesium sulphate (Mg) and/or L-tryptophan (Trp) in the diet for 5 days before slaughter. Animals were housed individually and were submitted to stressful ante mortem conditions (mixed in the lorry according to treatments and transported 1h on rough roads). Individual feed intake was recorded during the 5-day treatment. At the abattoir, pig behaviour was assessed in the raceway to the stunning system and during the stunning period by exposure to CO2. Muscle pH, colour, water holding capacity, texture and cathepsin activities were determined to assess meat quality. The number of pigs with an individual feed intake lower than 2kg/day was significantly different among diets (P<0.05; Control: 8.7%; Mg&Trp: 43.5%; Trp: 17.4%) and they were considered to have inadequate supplement intake. During the ante mortem period, 15.2% of pigs included in the experiment died, and this percentage decreased to 8.7% in those pigs with a feed intake > 2kg/day, all of them from the stress-sensitive pigs (nn). In general, no differences were observed in the behaviour of pigs along the corridor leading to the stunning system and inside the CO2 stunning system. During the stunning procedure, Trp diet showed shorter periods of muscular excitation than control and Mg&Trp diets. The combination of a stressful ante mortem treatment and Mg&Trp supplementation led to carcasses with high incidence of severe skin lesions. Different meat quality results were found when considering all pigs or considering only those with adequate supplement intake. In this later case, Trp increased pH45 (6.15) vs Control diet (5.96) in the Longissimus thoracis (LT) muscle (P<0.05) and pH at 24h (Trp: 5.59 vs C: 5.47) led to a higher incidence of dark, firm and dry (DFD) traits in SM muscle (P<0.05). Genotype affected negatively all the meat quality traits. Seventy-five percent of LT and 60.0% of the SM muscles from nn pigs were classified as pale, soft and exudative (PSE), while none of the NN pigs showed these traits (P<0.0001). No significant differences were found between genotypes on the incidence of DFD meat. Due to the negative effects observed in the Mg&Trp group in feed intake and carcass quality, the utilization of a mixture of magnesium sulphate and tryptophan is not recommended

El dia 9 de desembre de 2008 un col·lectiu d'estudiants de la UdG va ocupar el vestíbul de la Facultat d'Educació i Psicologia i l'Escola d'Infermeria. El motiu de l'ocupació era el de fer arribar la seva protesta respecte de l'aplicació de l'Espai Europeu d'Estudis Superiors. El dia 17 d'abril de 2009, després de 100 dies d'ocupació, els estudiants van desallotjar l'edifici pacíficament i voluntàriament

The objective of traffic engineering is to optimize network resource utilization. Although several works have been published about minimizing network resource utilization, few works have focused on LSR (label switched router) label space. This paper proposes an algorithm that takes advantage of the MPLS label stack features in order to reduce the number of labels used in LSPs. Some tunnelling methods and their MPLS implementation drawbacks are also discussed. The described algorithm sets up NHLFE (next hop label forwarding entry) tables in each LSR, creating asymmetric tunnels when possible. Experimental results show that the described algorithm achieves a great reduction factor in the label space. The presented works apply for both types of connections: P2MP (point-to-multipoint) and P2P (point-to-point)

The article is the result of an attempt to define universal categories which permit a nonandrocentric conceptualization of the natural environment, in which femenine experience in environmental topics is unveiled and emphatized as a collective heritage. The theoretic content concentrates on defining and outlining the characteristics of two basic concepts: the femenine model of conscience and environmental actionr and ccwomen's ecologismn. The potential of both concepts for structuring research in genderlenvironment relations is demostrated. Finally, the article offers reasoned criticism of the androcentric nature of the guide-lines which predominate in environmental management and proposes, as the basis of an alternative model, the recognition of the legitimacy and authority of feminine experience in environmental affairs

Va ser a mitjans de maig quan vam poder fer tangible el petit projecte que mesos enrere havíem estat elaborant. Uns cinquanta companys i companyes de Bilbo arribaven a Girona per poder participar a les Jornades d'Intercanvi sobre Educació Social
