Application of a GOY model to atmospheric boundary layer data
J. M. Vindel,C. Yagüe
Nonlinear Processes in Geophysics (NPG) , 2009,
Abstract: This article analyzes the possibility of applying a GOY theoretical model to atmospheric boundary layer data. Bearing this in mind, relative scaling exponents of velocity structure functions are used to compare the model with the data under study. In the model, these exponents are set based on two parameters (q and δ), which are appropriate to define the model that better features a certain atmospheric state. From these scaling exponents, the gap between 2-D and 3-D turbulence is observed in the model, depending on the fact that δ is higher or lower than unity, respectively. Atmospheric data corresponding to very different states of stratification stability have been analyzed. For convective or near-neutral situations (usually associated to 3-D turbulence), it is possible to find parameters q and δ to define a model that fits the measured data. More stable situations can be featured by GOY models with higher values of δ. However, it is clear that it is impossible to represent nocturnal situations of strong stable stratification (with a more similar behaviour to 2-D) with this type of model.

Abstract: the human genoma project (ghp) that started in 1990 is bringing forward relevant knowledge about the human genetic map. in order to be on a par with the recent scientific advances the health professionals should have the appropriate genetic training in order to provide a comprehensive health care. in the united states, some universities have included the subject of genetics in the nursing curriculum as part of the essential program in the educational training of the health professionals. by doing so, it allows the nursing role to have its own identity as genetic counsellor. in europe, the united kingdom is the country that considers in a more realistic and updated way the need of an educational training in genetic counselling for their health experts and their health policies are being orientated to cover these needs. in spain, however, this educational training is not enough. the reforms of the new contents of the nursing studies carried out in the european convergence (bologna 2010) should allow to incorporate genetics studies in order to prepare primary care nurses to address this issues in an effective way. as experts in comprehensive health care they should be able to take care of the individuals and their families in prevention.
Salud Pública y Genética: Nuevos retos para el profesional de enfermería Public Health and Genetics: new challengues for nursing professionals

Abstract: El proyecto Genoma Humano (HGP) iniciado en 1990 está aportando importantes conocimientos sobre el mapa genético humano. Para poder estar a la altura de estos avances científicos los profesionales de la salud han de tener la formación en genética necesaria a fin de brindar unos cuidados integrales de salud. En Estados Unidos, la Universidad ha incluido en el currículo de Enfermería la genética como parte integral de la formación de sus profesionales, permitiendo que el rol de la enfermera haya adquirido una identidad propia como enfermeras genetistas. En Europa, Inglaterra es el país que contempla de una manera más realista y actual la necesidad de formación de profesionales de la salud expertos en consejo genético, y sus políticas sanitarias están orientadas a paliar esta necesidad. En Espa a, sin embargo, esta formación es insuficiente y las reformas de los nuevos planes de estudios para la convergencia europea (Bolonia 2010) tienen que permitir incorporar contenidos en genética que preparen a las enfermeras de atención primaria para abordar estos temas de manera eficaz y saber dirigir, como expertas en el cuidado integral de la salud, a los individuos y sus familias hacia la prevención.

Structure function analysis and intermittency in the atmospheric boundary layer
J. M. Vindel, C. Yagüe,J. M. Redondo
Nonlinear Processes in Geophysics (NPG) , 2008,
Abstract: Data from the SABLES98 experimental campaign (Cuxart et al., 2000) have been used in order to study the relationship of the probability distribution of velocity increments (PDFs) to the scale and the degree of stability. This connection is demonstrated by means of the velocity structure functions and the PDFs of the velocity increments. Using the hypothesis of local similarity, so that the third order structure function scaling exponent is one, the inertial range in the Kolmogorov sense has been identified for different conditions, obtaining the velocity structure function scaling exponents for several orders. The degree of intermittency in the energy cascade is measured through these exponents and compared with the forcing intermittency revealed through the evolution of flatness with scale. The role of non-homogeneity in the turbulence structure is further analysed using Extended Self Similarity (ESS). A criterion to identify the inertial range and to show the scale independence of the relative exponents is described. Finally, using least-squares fits, the values of some parameters have been obtained which are able to characterize intermittency according to different models.
Influence of stability on the flux-profile relationships for wind speed, Φm, and temperature, Φh, for the stable atmospheric boundary layer
C. Yagüe, S. Viana, G. Maqueda,J. M. Redondo
Nonlinear Processes in Geophysics (NPG) , 2006,
Abstract: Data from SABLES98 experimental campaign have been used in order to study the influence of stability (from weak to strong stratification) on the flux-profile relationships for momentum, Φm, and heat, Φh. Measurements from 14 thermocouples and 3 sonic anemometers at three levels (5.8, 13.5 and 32 m) for the period from 10 to 28 September 1998 were analysed using the framework of the local-scaling approach (Nieuwstadt, 1984a; 1984b), which can be interpreted as an extension of the Monin-Obukhov similarity theory (Obukhov, 1946). The results show increasing values of Φm and Φh with increasing stability parameter ζ=z/Λ, up to a value of ζ≈1–2, above which the values remain constant. As a consequence of this levelling off in Φm and Φh for strong stability, the turbulent mixing is underestimated when linear similarity functions (Businger et al., 1971) are used to calculate surface fluxes of momentum and heat. On the other hand when Φm and Φh are related to the gradient Richardson number, Ri, a different behaviour is found, which could indicate that the transfer of momentum is greater than that of heat for high Ri. The range of validity of these linear functions is discussed in terms of the physical aspects of turbulent intermittent mixing.
The triassic alkaline dolerites of the Valacloche-Camarena Area (SE-Iberian Chain, Teruel): Geodynamic implications
Lago San José, M.,Galé Bomao, C.,Arranz Yagüe, E.,Gil Imaz, A.
Estudios Geologicos , 2000, DOI: 10.3989/egeol.00565-6139
Abstract: The dolerite sills outcropping in the Valacloche-Camarena area (SE Iberian Chain), are the expression of an alkaline magmatism, emplaced in Keuper facies sedimentary rocks. Their pre-Hettangian age is deduced from the development of fluidality structures at the top of the sills together with the very low grade contact metamorphism of the host rocks. A differentiation trend, represented by two rock-types, with variable Ti-augite content, is confirmed by geochemical data (REE). The alkaline composition of this magmatism is close to that of the OIB type. Crust-derived enclaves (metapelites and granitoids) are common in these sills, suggesting that magma ascent took place through a fracture system, related to a distensive tectonic regime, that affected different levels of the crust. This magmatism was one of the expressions of the triassic rifting events that are well represented in the SE border of the Iberian Chain. Un magmatismo alcalino, emplazado en sedimentos triásicos en facies Keuper, está bien representado en los sills doleríticos del área de Valacloche-Camarena (SE de la Cordillera Ibérica). La edad pre-Hettangiense ha sido deducida a partir de la presencia de estructuras de fluidalidad y de un metamorfismo de contacto de grado muy débil. Petrológicamente se identifica una fraccionación según dos litotipos (con contenido variable en Ti-augita) que está corroborada por los datos de composición geoquímica (en tierras raras); la composición alcalina de este magmatismo es próxima a la del tipo OIB. La presencia, frecuente, de enclaves de corteza (metapelitas y granitoides) indica una fracturación que, en condiciones distensivas, afectó a distintos niveles de dicha corteza. Este magmatismo está ligado al rifting triásico que está bien expresado en el borde SE de la Cordillera Ibérica.
Las doleritas toleíticas triásicas del sector SE de la Cordillera Ibérica: petrología y geoquímica

Abstract: The tholeiitic dolerites that crop out in three diapirs of the SE of the Iberian Chain (Alfarp, Quesa and Lugar Nuevo de Fenollet, Valencia), are the expression of evolved (low Ni, Cr and mg* values) basic magmas, injected into poorly lithified sediments (lutites, marls and gypsum) which represent the Upper Triassic (Keuper facies)-Hettangian boundary, developing sills with reduced thickness. Their mineral and whole-rock geochemical compositions indicate a continental tholeiitic affinity and certain similarities to a MORB composition and, on the other hand, show that the Alfarp dolerites represent the less evolved compositions, whereas the Fenollet dolerites show a significantly greater differentiation. These rocks are the expression of a shallow magmatism, related to the initial stages of the mesozoic rifting that affected the intersection of the Celtiberian Rift with the Betic Graben. This magmatism is clearly different of the isochronous tholeiitic magmatism (dolerites) which crops out at the Pyrenees and Betic. Las doleritas toleíticas aflorantes en diapiros triásicos del SE de la Cordillera Ibérica (Alfarp, Quesa y Lugar Nuevo de Fenollet, SE de Valencia) representan líquidos diferenciados (valores bajos en Ni, Cr y mg*) emplazados como sills, de escaso espesor, por debajo de sedimentos (arcillas, margas y yesos), poco consolidados, del límite Triásico superior-Hettangiense. Su composición mineral y geoquímica, con afinidad toleítica continental y similitud a MORB, evidencia el carácter menos diferenciado de las doleritas de Alfarp, respecto a las de Quesa, siendo las doleritas aflorantes en Fenollet las que presentan una composición más evolucionada. Estas doleritas son la expresión de un magmatismo poco profundo, asociado al inicio del rifting mesozoico, desarrollado en la zona de intersección del rift celtibérico y el borde NE del surco bético. Este magmatismo presenta claras diferencias respecto a las doleritas toleíticas, menos diferenciadas, de los dominios pirenaico y bético.
Chronic primary intestinal pseudo-obstruction from visceral myopathy Pseudo-osbtrucción intestinal crónica primaria debida a miopatía visceral
M. T. Mu?oz-Yagüe,J. C. Marín,F. Colina,C. Ibarrola
Revista Espa?ola de Enfermedades Digestivas , 2006,
Abstract: Chronic intestinal pseudo-obstruction is an uncommon syndrome characterized by relapsing episodes suggesting intestinal obstruction during which no mechanical causes are identified to account for symptoms. Etiologic factors may be manifold. Among them a number of neurologic conditions, gastrointestinal smooth muscle myopathies, endocrino-metabolic and autoimmune diseases, and the use of selected drugs stand out. We report a case of chronic intestinal pseudo-obstruction originating in a sporadic, primary intestinal myopathy that corresponds to no type thus far described. A histological study of the intestinal wall showed disrupted muscle bundles and the presence of interstitial edema. Myocytes had severe degenerative changes, and no alterations were seen in submucosal and myenteric plexus neurons. The activity of enzyme complexes in the mitochondrial respiratory chain, and of thymidine phosphorylase was normal. No mitochondrial DNA changes were seen. La pseudo-obstrucción intestinal crónica es un síndrome infrecuente caracterizado por episodios recidivantes, sugestivos de obstrucción intestinal, durante los cuales no se detectan causas mecánicas que justifiquen la sintomatología. Los factores etiológicos pueden ser múltiples. Entre ellos destacan diversas enfermedades neurológicas, miopatías de la musculatura lisa gastrointestinal, enfermedades endocrino-metabólicas y autoinmunes y el uso de determinados fármacos. Presentamos un caso de pseudo-obstrucción intestinal crónica originada por una miopatía intestinal primaria y esporádica que no corresponde a ningún tipo descrito hasta el momento. El estudio histológico de la pared intestinal mostró que los haces musculares estaban desestructurados y que existía edema intersticial. Los miocitos presentaban marcados cambios degenerativos y no existían alteraciones en las neuronas de los plexos submucoso y mientérico. La actividad de los complejos enzimáticos de la cadena respiratoria mitocondrial y de la timidina fosforilasa fue normal. No se detectaron alteraciones en el ADN mitocondrial.

Abstract: the main aim of this initiative is to promote a culture change in the prison/tobacco conjunction by means of an intervention program that leads to reduction in the high levels of smoking amongst the prison population (70-80%) and prison personnel. we hope to demonstrate that it is possible in practice to successfully implant and extend tobacco cessations programs in prisons. this would mean an important step forward for the general health of prison inmates, who suffer from higher levels of tobacco addiction than the general population and prison staff, who for their part are forced to share a reduced and enclosed space with prisoners.

Revista Espa?ola de Sanidad Penitenciaria , 2008,
Abstract: El principal objetivo de esta iniciativa es promover un cambio de cultura en torno al binomio cárcel y tabaco mediante un programa de intervención que conduzca a una reducción del elevado porcentaje de tabaquismo entre la población interna, 70 a 80 %, y los trabajadores del medio penitenciario. Queremos demostrar, en la práctica, que es posible implantar y generalizar con éxito programas de abandono de la dependencia del tabaco en los Establecimientos penitenciarios. Esto supone un paso importante en la mejora de la salud global de los internos que sufren una mayor prevalencia de tabaquismo que la población general y de los trabajadores penitenciarios, que comparten con ellos un espacio reducido y cerrado.
