La información televisiva durante la crisis del Prestige. Anàlisis de contenido de los noticiarios de TVE1, TV3, Antena 3 y telecinco

La catàstrofe mediambiental generada per l’enfonsament del petroler Prestige enfront de les costes gallegues al 2002 ha estat un dels majors desastres ecològics a Espanya i les seves conseqüències es van estendre al terreny polític i social, generant una situació de crisi sense precedents al territori espanyol. Aquest treball de recerca inclou el marc teòric, la metodologia i els primers resultats de l’estudi de la informació televisiva emesa per quatre cadenes generalistes de televisió durant tota la crisi. A més d’una revisió crítica de les teories de la comunicació i els seus mètodes d’investigació, s’ofereix un estudi sobre el concepte i l’estructura del noticiari televisiu, així com unes notes introductòries sobre la cobertura de cada cadena.

A simple method to purify biologically and antigenically preserved bloodstream trypomastigotes of Trypanosoma cruzi using Deae-cellulose columns

A method to purify trypanosomastigotes of some strains of Trypanosoma cruzi (Y, CL, FL, F, "Berenice", "Colombiana" and "São Felipe") from mouse blood by using DEAE-cellulose columns was standardized. This procedure is a modification of the Lanham & Godfrey methods and differs in some aspects from others described to purify T. cruzi bloodstream trypomastigotes, mainly by avoidance of prior purifications of parasites. By this method, the broad trypomastigotes were mainly isolated, accounting for higher recoveries obtained with strains having higher percentages of these forms: processing of infected blood from irradiated mice could be advantageous by increasing the recovery of parasites (percentage and/or total number) and elution of more slender trypomastigotes. Trypomastigotes purified by this method presented normal morphology and motility, remained infective to triatomine bugs and mice, showing in the latter prepatent periods and courses parasitemia similar to those of control parasites, and also reproducing the polymorphism pattern of each strain. Their virulence and pathogenicity also remained considerably preserved, the latter property being evaluated by LD 50 tests, mortality rates and mean survival time of inoculated mice. Moreover, these parasites presented positive, clear and peripheral immunofluorescence reaction at titres similar to those of control organisms, thus suggesting important preservation of their surface antigens.

A simple method for assessing the binding of concanavalin A to mononuclear cell surfaces: no interference of visceral leishmaniasis serum on this binding

We report a simple method for evaluating the binding of concanavalin A (ConA) to human peripheral blood mononuclear cells (PBMC). The binding is evidenced by an immunoenzymic assay using peroxidase-conjugated immunoglobulins of a rabbit anti-ConA serum. Using the method we show that sera from patients with American leishmaniasis do not interfere with binding of ConA to PBMC.

Análisis y diseño de un procesador RISC simple para adquisición y proceso de datos

Aquest projecte té com a objectiu l'anàlisi de prestacions de processadors RISC de baix cost i el disseny d'un processador RISC simple per a aplicacions de propòsit general relacionades amb l'adquisició i el procés simple de dades. Com a resultat es presenta el processador SR3C de 32 bits i arquitectura RISC. Aquest processador s'ha descrit i simulat mitjançant el llenguatge de descripció de hardware VHDL i s'ha sintetitzat en una FPGA. El processador està preparat per poder utilitzar-se en SoCs reals gràcies al compliment de l'estàndard de busos Wishbone. A més també es pot utilitzar com plataforma educativa gràcies a l'essamblador i simulador desenvolupats.

PulseCath iVAC 3LTM hemodynamic performance for simple assisted flow.

The PulseCath iVAC 3L? left ventricular assist device is an option to treat transitory left heart failure or dysfunction post-cardiac surgery. Assisted blood flow should reach up to 3 l/min. In the present in vitro model exact pump flow, depending on various frequencies and afterload was examined. Optimal flow was achieved with inflation/deflation frequencies of about 70-80/min. The maximal flow rate was achieved at about 2.5 l/min with a minimal afterload of 22 mmHg. Handling of the device was easy due to the connection to a standard intra-aortic balloon pump console. With increasing afterload (up to a simulated mean systemic pressure of 66 mmHg) flow rate and cardiac support are in some extent limited.
