II Congreso español de gestión integral de deyecciones ganaderas : Barcelona, 9-10 de junio 2010. International workshop on anaerobic digestion of slaughterhouse waste : Barcelona, 11 junio 2010

La fuerte demanda de alimentos que ha tenido lugar a nivel mundial en los últimos años, ha provocadoun cambio en los sistemas de producción agraria y para el caso de la ganadera se ha pasado de lastípicas explotaciones extensivas ligadas al terreno a las granjas intensivas, en donde se ha incrementadola carga ganadera, bien aumentando el número de cabezas en pastoreo o mediante la construcción degranjas intensivas sin suelo

Die ersten offiziellen Ausgrabungen in Ampurias (Empuries, L'Escala, Provinz Girona): 1846

En el año 2008 tuvo lugar el aniversario del centenario de las excavaciones arqueológicas en la ciudad greco-romana de Ampurias. Precisamente las investigaciones de esa época tienen un significado cultural y simbólico muy importante para el desarrollo de la autognosis de Cataluña a comienzos del siglo XX. El presente artículo intenta llamar la atención sobre los verdaderos comienzos de las investigaciones sobre la antigua ciudad, que habían comenzado bastante antes. Si nos concentramos en considerar los lugares de patrocinio público las excavaciones privadas fueron habituales en todas las épocas entonces las excavaciones científicas comenzaron siete décadas antes. Responsable fue la Comisión de Monumentos de Girona, que contó con el apoyo financiero de la Diputación Provincial.

Somatización y conflictos cognitivos: estudio exploratorio con una muestra clínica

Los problemas de somatización generan un elevado consumo de recursos y algunos tratamientos habituales resultan ineficaces o contraproducentes. Parece necesario un abordaje multidisciplinar que ofrezca un tratamiento integral a estos pacientes. Esta perspectiva debería tener en cuenta factores cognitivos poco estudiados como la construcción subjetiva del sí mismo, los síntomas y los demás. De ahí el interés de estudiar los conflictos cognitivos, que podrían erigirse en barreras subjetivas para la curación. El objetivo de este estudio es investigar las relaciones entre los dilemas implicativos, un tipo de conflicto cognitivo que puede detectarse con la Técnica de Rejilla, y una escala de somatización. Los resultados sugieren que las puntuaciones en somatización son más elevadas en personas con dilemas implicativos, y la presencia de estos conflictos predice mejor la somatización que el sexo, la edad, la autoestima o la diferenciación cognitiva.

Tratamento dos resíduos gerados na síntese de polianilina em escala pré-piloto

Polyaniline (PAni) is one of the most studied conducting polymer. It can be synthesized by two methods: electrochemical or chemical oxidation. The chemical oxidation is more adequate to produce large quantities of polymer. Regardless of the synthesis scale, the treatment of the residues before its final destination is very important and necessary because it contains toxic aniline derivatives (carcinogens in some cases), acids and inorganic salts, both with low toxicity. In this work we discuss the methods used to treat these residues and to eliminate and discard the toxic substances. These were extracted from the reaction residues by using activated coal and the pH of the residue was neutralized.

Síntese de sulfadiazina e sulfadiazina de prata em escala semi-micro: prática experimental em síntese de fármacos

The total synthesis of sulfadiazine and silver sulfadiazine from readily available starting materials was adapted to semi-micro laboratory scale and is proposed as an experiment in drug synthesis for undergraduate courses.

Cromatografia em leito móvel simulado na produção de substâncias enantiomericamente puras ou enriquecidas em larga escala

There is great interest nowadays in the use of preparative liquid chromatography as an effective tool for the production of enantiomerically pure, or enriched, compounds for the pharmaceutical industry. To make the chromatographic process economically attractive, attention is now focused on the choice of the chromatographic operating mode to minimize eluent consumption and to maximize productivity. Among the alternatives to the traditional batch chromatography, attention is now shifting towards simulated moving bed (SMB) technologies and a review covering the latest developments in this area seems timely. Several aspects of this important analytical technique are presented and details concerning the SMB technology for process optimization are outlined.

La evaluación del estrés y del trauma: presentación de la versión española de la escala de trauma acumulativo (CTS)

This paper reviews some of the most usual definitions of stress and trauma including the notion of accumulative trauma. Then, the Spanish version of the Cumulative Trauma Scale by Kira et al (2008) is presented. It has been developed by following a process of translation and by applying it to two small groups of subjects to test it for comprehension (pilot test).

Repensando la relación entre la ley y la violencia hacia las mujeres. Una aproximación a los discursos de los/las agentes del ámbito judicial en relación a la ley integral de violencia de género en España = Rethinking the relationship between law and violence against women. an approach to the juridical agents' discourses in relation to the integral law of gender-based violence

Of the many dimensions of the problem of violence exercised by men toward women in the context of the relations of partner or ex partner, this article deals with the analysis of the discursive productions of the institutional actors that are part of the judicial process. Our intention is to investigate the relationship between criminal law and gender-based violence starting from the implementation of the Law of Integral Gender-based Violence in Spain (LO. 1 / 2004) from a theoretical perspective which includes contributions from social psychology, and socio-legal feminism. We have approached the legal instrument - the Law of Integral Gender-based Violence - through the discourse of legal officers with a perspective that questions the values, so often proclaimed, of universality, objectivity and neutrality of the law

Escala de satisfacción con el tratamiento recibido (CRES-4): la versión en español

The satisfaction of consumers and users with the products and services is an issue that in recent years has been taking more and more importance and now it even reaches psychotherapy. This paper presents the Spanish adaptation of the Consumer Reports Effectiveness Scale (CRES-4)consisting of four items designed to evaluate whether patients are satisfied with the therapy they have received and if it has been perceived as effective or not. Its global score is intended to reflect treatment effectiveness as percived by the patient. Existing studies suggest that the CRES-4 is a good complementary tool to judge, in particular, satisfaction with treatment received.

Avaliação em escala laboratorial da utilização do processo eletrolítico no tratamento de águas

Water treatment uses chlorine for disinfection causing formation of trihalomethanes. In this work, an electrolytic water pre-treatment was studied and applied to the water from a fountainhead. The action against microorganisms was evaluated using cast-iron and aluminum electrodes. Assays were made in laboratory using the electrolytic treatment. After 5 min of electrolysis the heterotrophic bacteria count was below 500 cfu/mL and complete elimination of total and fecal coliforms was observed. Using electrolytic treatment as a pretreatment of conventional tap water treatment is proposed.

Análisis psicométrico de la escala multidimensional de autoconcepto AF5 en una muestra de adolescentes y adultos de Cataluña

Psychometric analysis of the AF5 multidimensional scale of self-concept in a sample of adolescents and adults in Catalonia. The aim of this study is to carry out a psychometric study of the AF5 scale in a sample of 4.825 Catalan subjects from 11 to 63 years-old. They are students from secondary compulsory education (ESO), from high school, middle-level vocational training (CFGM) and from the university. Using a principal component analysis (PCA) the theoretical validity of the components is established and the reliability of the instrument is also analyzed. Differential analyses are performed by gender and normative group using a 2 6 factorial design. The normative group variable includes the different levels classifi ed into 6 sub-groups: university, post-compulsory secondary education (high school and CFGM), 4th of ESO, 3rd of ESO, 2nd of ESO and 1st of ESO. The results indicate that the reliability of the Catalan version of the scale is similar to the original scale. The factorial structure also fi ts with the original model established beforehand. Signifi cant differences by normative group in the four components of self-concept explored (social, family, academic/occupational and physical) are observed. By gender, signifi cant differences appear in the component of physical self-concept, academic and social but not in the family component

Polarimetric 3D integral imaging in photon-starved conditions

We develop a method for obtaining 3D polarimetric integral images from elemental images recorded in low light illumination conditions. Since photon-counting images are very sparse, calculation of the Stokes parameters and the degree of polarization should be handled carefully. In our approach, polarimetric 3D integral images are generated using the Maximum Likelihood Estimation and subsequently reconstructed by means of a Total Variation Denoising filter. In this way, polarimetric results are comparable to those obtained in conventional illumination conditions. We also show that polarimetric information retrieved from photon starved images can be used in 3D object recognition problems. To the best of our knowledge, this is the first report on 3D polarimetric photon counting integral imaging.

Estudio y tratamiento integral del dedo en garra

Básicamente las desviaciones de los dedos medios que a diario nos encontramos en las exploraciones podológicas, son de dos tipos: - Deformaciones longitudinales en el plano sagital: dedos en garra o en martillo con sus múltiples variantes. - Deformaciones laterales en el plano frontal: clinodactilias con dedos supra e infraductus.

La escala de análisis: un tema central en didáctica de la geografía = The scale of analysis a central didactic theme in Geography

Geographical scale is not merely a technical question. The learning of geographical scale goes beyond geometricunderstanding; it implies the etymological comprehension of the concept, the recognition of the importance of scale in theelaboration of the geographical discourse. It implies placing oneself in the centre of the teaching and learning of Geographyand asking oneself, what scale? Why this scale? What progression of scales? The answer to these questions puts in doubtthe scientific discourse that is presently taught in schools especially on the scale of analysis, the sequencing of studiedspaces and the false dichotomy local and global

Otra mirada al tema del cambio de escala: los nuevos espacios de comercio, ocio y turismo = Another look at the theme of the change of scale: new spaces in commerce, leisure and tourism

The technological advances and new organisation of the economy together with a change in ideas in consumer habits andlifestyle that have happened in the last 25 years have placed us in a new state of capitalism. The spatial translation of thisnew state has been immediate and implies among other changes the overcoming of the concept of scale. Commercialspaces and those of leisure and tourism offer us an unbeatable opportunity of exemplifying these changes because they arethe most effected by the new postmodern tendencies
