Conflictivitat i ruptura en el matrimoni
Es tracta de la intensa i generalitzada crisi del matrimoni, de profunda i àmplia repercussió social, basant-se en documentats estudis i fidedignes estadístiques. Es desenvolupa una tipologia de les situacions d’exclusió, tensió, conflictivitat i ruptura que es donen en relació amb el matrimoni. Sintetitzada, és la següent: a) unions sense lligam jurídic; b) conflictivitat en el si del matrimoni:, c,) doblatge entre la vida conjugal i unes relacions sexuals extramatrimonials; d) separacions merament de fet o a través d’un conveni; e) separació judicial o administrativa, mantenint-se el vincle; f ) nova convivència fixa amb tercera persona; g) assoliment d’una sentència de divorci vincular; h) obtenció d’una resolució judicial que declari nul el matrimoni o d’una dispensa que el deixi sense efecte. S’inclou el resultat d’una anàlisi sociològica efectuada sobre una mostra de les causes de separació conjugal introduïdes al Tribunal Eclesiàstic de Barcelona en el període 1968-1974. Es destaca la importància, a part de consideracions jurídiques, de l’existencia d’un veritable amor psíquic i sexual, d’una compenetració intel·lectual i afectiva, que faci veritablement estable la unió matrimonial i que permeti de superar les influències derivades, en bona part, de la massificació, del materialisme egoista i del consumisme, existents en la societat capitalista i que porten a la tensió, a la conflictivitat i a la ruptura matrimonial
Mechanisms of dexamethasone-mediated chemokine down-regulation in mild and severe acute pancreatitis
AbstractThis study aimed to investigate the role of therapeutic dexamethasone (Dex) treatment on the mechanisms underlying chemokine expression during mild and severe acute pancreatitis (AP) experimentally induced in rats. Regardless of the AP severity, Dex (1 mg/kg), administered 1 h after AP, reduced the acinar cell activation of extracellular signal-regulated kinase (ERK) and c-Jun-NH2-terminal kinase (JNK) but failed to reduce p38-mitogen-activated protein kinase (MAPK) in severe AP. In both AP models, Dex inhibited the activation of nuclear factor-kappaB (NF-κB) and signal transducers and activators of transcription (STAT) factors. All of this resulted in pancreatic down-regulation of the chemokines monocyte chemoattractant protein-1 (MCP-1) and cytokine-induced neutrophil chemoattractant (CINC). Lower plasma chemokine levels as well as decreased amylasemia, hematocrit and plasma interleukin-1β (Il-1β) levels were found either in mild or severe AP treated with Dex. Pancreatic neutrophil infiltration was attenuated by Dex in mild but not in severe AP. In conclusion, by targeting MAPKs, NF-κB and STAT3 pathways, Dex treatment down-regulated the chemokine expression in different cell sources during mild and severe AP, resulting in decreased severity of the disease
Influence of Recycled Precast Concrete Aggregate on Durability of Concrete's Physical Processes
ABSTRACT: The research presented in this article analysed the influence of incorporating precast concrete waste as an alternative to coarse aggregate in self-compacting concrete to generate new precast elements. The experimental study involved the characterization of recycled aggregate and the design of the mix of the new self-compacting concrete (SCC). The experimental study evaluates the physical processes that affect the durability of concrete with percentages of incorporation such as 20%, 50% and 100% of recycled aggregate. Two types of SCC were manufactured with minimum compressive strength of 30 MPa and 45 MPa. The properties analysed were density of hardened SCC, shrinkage cracking, freeze-thaw resistance, resistance to ageing by thermal shock and abrasion resistance. The results obtained were compared with those of the control concrete, observing great capacity of the SCC under physical aggressions that affect durability. The results of this research show that it is possible to use the recycled aggregate coming from precast pieces in order to the manufacture of self-compacting recycled concrete in the same precast industry. However, high loss of proprieties occurs for a 100% substitution, while for 20% and 50%, the variations with respect to control concrete are smaller. In addition, taking advantage of this waste to incorporate it back into the production chain contributes to more sustainable construction.This research was funded by Junta de Castilla y León (Regional Government) for funding UIC-231 through

Sustainable bioethanol production using agro-industrial by-products
This work aimed to evaluate a sustainable bioethanol production by a laboratorial isolate strain of
Saccharomyces cerevisiae, along with the use of agro-industrial by-products as carbon source. The effect of
several carbon sources and their concentrations was studied using carob pod extract (CPE) and beet molasses
(BM) and compared with glucose and sucrose as conventional carbohydrates at different concentrations, 15, 20
and 30 g/l.No significant difference was found between maximum ethanol production obtained with CPE, BM,
glucose and sucrose fermentations profiles. It was obtained values of 10.65 g/l and 10.5 g/l ethanol, respectively
for sucrose and CPE at 30g/l, which can be improved using higher substrate concentration

El efecto de exposición en el patrón sedimen- tario del sector submareal de tres playas en la Ría de Muros y Noia (NO de España)
En este trabajo se presenta la comparación de los sedimentos superficiales de la plataforma proximal de tres complejos playeros situados en las inmediaciones de la embocadura de la Ría de Muros y Noia. En cada uno de ellos, se han identificado las distintas poblaciones sedimentarias en función de los análisis granulométricos realizados. La aplicación de un análisis estadístico de componentes principales a las fracciones granulométricas, contenido en carbonatos y materia orgánica, ha permitido diferenciar poblaciones de muestras y la interpretación sedimentaria de las mismas. Las diferencias observadas en la distribución de las poblaciones sedimentarias de los tres complejos estudiados son una consecuencia del grado de exposición de cada complejo al oleaje dominante y de la presencia de afloramientos rocosos sumergidos que ejercen un efecto barrera.The subaquatic sediments from the inner continental shelf of three beach systems located in the surrondings of Ría de Muros y Noia mouth are compared. Different sedimentary populations have been stablished according to the granulometric distribution from each system. The grain-size distribution, carbonate and organic matter content have been compared by means of a principal component analysis. The results allow the identification of different populations as well as their sedimentary significance. The observed differences between the sedimentary populations from each system are explained as a consequence of their grade of exposure towards the dominant waves and the presence of subaquatic rocks, which introduce a barrier effect
