Masonry bell towers. Dynamic considerations

[EN] The building of masonry bell towers was customary in Europe until the beginning of the twentieth century. At the present time, most of the work carried out on these structures involves either conservation or rehabilitation, owing to their considerable historical value. One of the forces that can have an influence on the behaviour of a bell tower is that caused by the turning/oscillation of the bells themselves. This is a dynamic force and may interact with the tower's natural frequencies. This paper describes the effect of bell-ringing on masonry towers. The towers are classified and a series of data are offered to characterise their behaviour. Finally, a procedure is described that permits an assessment to be made of this type of structure.Pallarés Rubio, FJ.; Ivorra Chorro, S.; Adam Martínez, JM. (2011). Masonry bell towers.

Documento de consenso SEA/SEMERGEN 2019. Recomendaciones dietéticas en la prevención cardiovascular

El actual paradigma en las ciencias de la nutrición establece que la unidad nutricional básica no son los nutrientes, sino los alimentos que los contienen (aceites, frutos secos, productos lácteos, huevos, carnes rojas o procesadas, etc.), que actúan como matriz alimentaria en la que los diferentes nutrientes modulan sinérgica o antagónicamente sus efectos sobre diversas vías metabólicas determinantes para la salud y la enfermedad. La alimentación no se basa en nutrientes ni en alimentos aislados sino en complejas mezclas de unos y otros que forman parte de un patrón alimentario concreto, concepto que se ha señalado como el más pertinente para evaluar las asociaciones entre nutrición y salud o enfermedad. Este documento resume las evidencias disponibles sobre la relación existente entre los diferentes alimentos y la salud cardiovascular, y ofrece recomendaciones sencillas para ser implementadas en el consejo dietético que se ofrezca por parte del profesional sanitario

Parálisis posterior en una vaca Holstein con Leucosis Enzoótica Bovina

ABSTRACT: A 6 year-old Holstein cow was euthanized after a 3 week course of progressive paraplegia. In spite of the increasing difficulties to rise and walk, the animal remained bright, alert, afebrile and with good appetite throughout most of the clinical course. Complete blood counts, biochemical profiles and analysis of the cerebrospinal fluid were reported within normal limits. Antibody was detected for bovine leukaemia virus using an enzyme-linked immunosorbent assay, supporting a tentative diagnosis of bovine leukosis. Post-mortem examination revealed a localized form of lymphosarcoma with few 2-5 cm nodular tumors confined to the walls of the gastrointestinal tract, particularly in the abomasum. In addition, soft grey tumors were found within the vertebral canal surrounding the lumbar spinal cord and associated nerve roots. Microscopic examination revealed the nodular masses were composed of neoplastic lymphocytes. Mass in the lumbar vertebral canal had extradural neoplastic lymphocytes infiltrating connective tissues around the spinal cord and spinal nerve roots. Unlike the more common chronic and wasting presentation of the disease with widespread lymphadenopathy, the rapid progression of the disease to total paraplegia in this animal could be explained by the localized presence of tumors in the spinal canal.RESUMEN: Una vaca Holstein de 6 años de edad fue sacrificada después de un curso de paraplejía progresiva de 3 semanas de duración. A pesar de las crecientes dificultades para levantarse y caminar, el animal se mantuvo alerta, sin fiebre y con buen apetito casi todo el transcurso de la enfermedad. Los análisis del hemograma, perfil bioquímico y líquido cefalorraquídeo no mostraron alteraciones fuera del rango normal. El análisis de ELISA frente al virus de la Leucosis Bovina resultó positivo, apoyando el diagnóstico diferencial de leucemia. El examen post-mortem reveló una forma localizada de linfosarcoma, con escasas y pequeñas tumoraciones nodulares de 2-5 cm confinadas a las paredes del tracto gastrointestinal, sobre todo en el abomaso. Además, los tumores estaban presentes en el canal vertebral rodeando la médula lumbar espinal y raíces nerviosas adyacentes. El examen microscópico reveló que las masas nodulares estaban compuestas de linfocitos neoplásicos; igualmente, el tejido conectivo rodeando la medula lumbar presentaba gran infiltración de dichos linfocitos. A diferencia de la presentación más corriente y crónica de la enfermedad en que existe un desgaste progresivo del animal asociado a una linfadenopatía generalizada, en este caso la rápida progresión de la enfermedad hacia una paraplejia total se podría explicar por la presencia de tumores localizados en el canal espinal

Diverse Large HIV-1 Non-subtype B Clusters Are Spreading Among Men Who Have Sex With Men in Spain

In Western Europe, the HIV-1 epidemic among men who have sex with men (MSM) is dominated by subtype B. However, recently, other genetic forms have been reported to circulate in this population, as evidenced by their grouping in clusters predominantly comprising European individuals. Here we describe four large HIV-1 non-subtype B clusters spreading among MSM in Spain. Samples were collected in 9 regions. A pol fragment was amplified from plasma RNA or blood-extracted DNA. Phylogenetic analyses were performed via maximum likelihood, including database sequences of the same genetic forms as the identified clusters. Times and locations of the most recent common ancestors (MRCA) of clusters were estimated with a Bayesian method. Five large non-subtype B clusters associated with MSM were identified. The largest one, of F1 subtype, was reported previously. The other four were of CRF02_AG (CRF02_1; n = 115) and subtypes A1 (A1_1; n = 66), F1 (F1_3; n = 36), and C (C_7; n = 17). Most individuals belonging to them had been diagnosed of HIV-1 infection in the last 10 years. Each cluster comprised viruses from 3 to 8 Spanish regions and also comprised or was related to viruses from other countries: CRF02_1 comprised a Japanese subcluster and viruses from 8 other countries from Western Europe, Asia, and South America; A1_1 comprised viruses from Portugal, United Kingom, and United States, and was related to the A1 strain circulating in Greece, Albania and Cyprus; F1_3 was related to viruses from Romania; and C_7 comprised viruses from Portugal and was related to a virus from Mozambique. A subcluster within CRF02_1 was associated with heterosexual transmission. Near full-length genomes of each cluster were of uniform genetic form. Times of MRCAs of CRF02_1, A1_1, F1_3, and C_7 were estimated around 1986, 1989, 2013, and 1983, respectively. MRCA locations for CRF02_1 and A1_1 were uncertain (however initial expansions in Spain in Madrid and Vigo, respectively, were estimated) and were most probable in Bilbao, Spain, for F1_3 and Portugal for C_7. These results show that the HIV-1 epidemic among MSM in Spain is becoming increasingly diverse through the expansion of diverse non-subtype B clusters, comprising or related to viruses circulating in other countries

La cinquena edició del microrelatari per l’eradicació de la violència contra les dones de l’Institut Universitari d’Estudis Feministes i de Gènere «Purificación Escribano» de la Universitat Jaume I vol ser una declaració d’esperança. Aquest és el moment en el qual les dones (i els homes) hem de fer un pas endavant i eliminar la violència sistèmica contra les dones. Ara és el moment de denunciar el masclisme i els micromasclismes començant a construir una societat més igualitària. Cadascun dels relats del llibre és una denúncia i una declaració que ens encamina cap a un món millor
