Abstract: the male body image has been a subject of interest and concern in recent years, with muscle dysmorphia attracting most attention. this is a study of differential aspects of body image, physical self-description, social and physical anxiety, and some behaviour aspects related to bodybuilders. seventy-one (36.24%) competing bodybuilders, 79 (36.24%) non-competing bodybuilders and 68 (31.19%) sedentary participants take part. they are all men. as opposed to the non-competitors, it is the competitors who mostly admit to comparing themselves physically with other gym colleagues (chi2=9.993, p=0.002), who rate themselves negatively after these comparisons (chi2=21.571, p=0.000) and who avoid showing their bodies in non-sporting environment (chi2=3.88, p=0.049); although they don?t differ in the time they spend thinking that they are not very muscular or concerned with their image (t=1,742, p=0,084). additionally, this same group recognises a greater number of checking behaviours - looking at themselves in the mirror (t=2.644, p=0.01) and weighing themselves (t=2.321, p=0.022). in the body shape questionnaire there are no differences between groups, except when the active ones are considered together as opposed to the sedentary ones, since this group showed a greater desire to lose weight (t=2.241, p=0.026). with respect to the two active groups, they see themselves better individually in comparison to the non-active and sedentary groups in physical self-description (f=9.472, p=0.000), health aspects (f=2.988 p=0.052), the body as a whole (f=17.806 p=0.000) and self-esteem (f=9.290, p=0.000), as well as in their fitness self-description (f=39.791, p=0.000), regarding aspects of fitness (f=16.889, p=0.000), strength (f=50.507, p=0.000), stamina (f=17.576, p=0.000) and physical activity (f=119.405, p=0.000). on the other hand, in terms of social physical anxiety levels, the two active groups scored higher than the sedentary group in the global value of the scale (f=15.353, p

Abstract: we plan to bring forward data which will enable us to carry out an approximation of the addiction to training in a group of bodybuilding competitors about which there has been no information up to now in spain. 116 male subjects filled in the ramón y cajal general addiction scale. 64 (55.17%) of these were considered new to muscular training and 52 (44.83%) were competitors. the competitor bodybuilders have shown a significantly better punctuation in all the dimensions of the general addiction scale (craving: t = 2.81, p = 0.006; withdrawal: t = 3.59, p = 0.000; lack of control: t = 3.59, p = 0.000; total: t = 3.88, p = 0.000) except that of tolerance (t = 1.44, p = 0.153). in the same way, in the analysis of variables related to training we have been able to see that those who normally stay training longer than planned, or who usually feel bad the days they don't train, have tried to lower the level of training, without success, or who usually look bad after comparing themselves physically to other gym mates, tend to show higher values both in the total punctuation and in the majority of the dimensions of the scale.

Caracterización de tintas de titanio dopadas con óxidos metálicos
Tubío, C. R.,Guitián, F.,Gil, A.
Boletín de la Sociedad Espa?ola de Cerámica y Vidrio , 2009,
Abstract: Sol-gel Inks based in titanium diisopropoxide bisacetylacetonate were prepared to develop nanostructures using the direct ink writing technique. This technique facilitates the structuring of materials by micro extrusion for the fabrication of three-dimensional photonic crystals with high refractive index at micro and nano scale. Thermal treatment of extruded nanostructures at high temperatures to transform them on TiO2 structures with high refractive index causes grain growth of TiO2. Calcining at higher temperatures must be avoided to prevent significant grain growth that can cause degradation of optical properties of the structure. Low temperatures of calcination lead to a poor mechanical stability of the structures. To increase the mechanical stability of the structures avoiding the growth of grain size during calcination, inks based on titanium diisopropoxide bisacetylacetonate were doped with niobium and zinc compounds. Using high-resolution X-ray diffraction, we studied the influence of the niobium and zinc oxides over the grain growth of TiO2 calcinating at different temperatures, and doing so evaluating the use of these dyes doped photonic applications. The results indicate that the addition of metal oxides has a significant effect on temperature conversion of anatase to rutile and depresses the grain growth of TiO2. Se prepararon tintas de Diisopropoxido de titanio bis(acetilacetonato) por el método sol-gel para aplicar en la elaboración de nanoestructuras mediante la técnica de escritura directa. Esta técnica permite estructurar materiales con alto índice de refracción a escala micro y nanométrica en tres dimensiones mediante extrusión, para elaborar cristales fotónicos. El tratamiento de las nanoestructuras extruidas a temperaturas elevadas para transformarlas en otras de TiO2 con alto índice de refracción, provoca crecimiento de grano del TiO2, lo que degrada sus propiedades ópticas, mientras que bajas temperaturas de calcinación, conducen a una pobre estabilidad mecánica de las estructuras. Para aumentar la estabilidad mecánica evitando a la vez el incremento del tama o de grano tras la calcinación, se doparon las tintas con compuestos de Niobio y Zinc. Mediante difracción de rayos X de alta resolución se estudió la influencia del dopante en el crecimiento de grano del TiO2 a distintas temperaturas de calcinación para así evaluar las posibilidad de utilizar dichas tintas dopadas para aplicaciones fotónicas. Los resultados obtenidos indican que la adición de dopantes basados en óxidos metálicos tiene un significativo efecto en la temperatura

Acta Montanistica Slovaca , 2005,
Abstract: Because of qualitative changes in the precision of the apparatus and the methods of determination of the space position of points on the earth surface (GPS method), as well as because of the fact that in the measurement there are shifts (observed points) relatively to the near surroundment (reference points), posibilities of the use of these technologies and apparatus are studied also in the engineering geodesy – the field to which the measurements of deformation belong. The article presents results of the experimental confirmation of the GPS method in the determination of positional shifts of the ground dam Liptovská Mara.
Emplazamiento hacia el ENE del manto de Los Reales (Alpujarrides occidentales): criterios estructurales y de petrofábrica
Tubía, J. M.
Estudios Geologicos , 1984,
Abstract: Los Reales nappe rests over Ojén nappe to the North of Sierra Alpujata. The nappe contact zone shows a intense plastic deformation with mylonitic rocks, The deformation decreases progressively going away from the contacto The structural study of footwall and hangingwall roen permits to attribute this deformation to the Los Reales nappe emplacement over that of Ojén. The foliation and stretching lineation distributions show a WSW-ENE shear direction. The mylonite microstructural characteristics and the enstatite crystalline preferred orientations in the basal peridotites give a mear sense in according that, Los Reales nappe is displaced, in their present position, from the WSW towards the ENE. El manto de Los Reales descansa sobre el manto de Ojén, al norte de Sierra Alpujata. La zona de contacto entre mantos exhibe una intensa deformación plástica con rocas miloníticas; la deformación disminuye progresivamente al alejarse del contacto. El estudio estructural de las rocas infra y suprayacentes al contacto permite atribuir esta deformación al emplazamiento del manto de Los Reales sobre el de Ojén. , Las distribuciones de la foliación y de la lineación, de estiramiento indican una dirección de cizallamiento WSW-ENE. Las características microestructurales de las milonitas y las orientaciones preferentes cristalinas de la enstatita en las peridotitas basales proporcionan un sentido de cizallamiento tal que el manto de Los Reales se ha desplazado, en su posición actual, desde el WSW hacia el ENE.
Significado de las deformaciones internas en las peridotitas de Sierra Alpujata (Málaga)
Tubía, J. M.
Estudios Geologicos , 1985,
Abstract: The Ronda peridotites rest at the base of the Los Reales nappe (Alpujarride Complex, Betic Chain). Two successive plastic deformations are imprinted in the Sierra Alpujata peridotites. The first one is a high temperature (> 1000o C) -low stress (0.3-0.5 Kb) deformation as show by coarse-grained porphyroclastic lherzolites. This deformation can take place by mantle flow in a spreading zone related to continental rifting. The second deformation. at low temperature (~8000o C) and high stress (1-2 Kb), erase the last one at the edge rones of the peridotite sheet, giving the mylonitisation of peridotites and the development of dynamothermal aureoles in the wall rocks, This deformation is due to the thrusting of a mantle slab over the continental crust. The kinematic analysis of the high and low-temperature ultrabasic tectonites provides, in the present position of the Betic Chain a N 70o E direction for the paleorift. The peridotite thrusting is practically realized in the same direction, from the WSW to the ENE. Las peridotitas de Ronda (Málaga) forman la base del manto de Los Reales (Alpujárrides, Cordilleras Béticas). Las rocas ultrabásicas del macizo de Sierra Alpujata permiten reconocer dos deformaciones plásticas sucesivas. La primera es una deformación de altas temperaturas (> 1.000oC) y bajos esfuerzos (0.3-0.5 Kb) que se conserva en lherzolitas con textura porfiroclástica de grano grueso. Esta deformación puede atribuirse al flujo del manto en una zona de expansión relacionada a procesos de "rifting" continental. La segunda deformación, de bajas temperaturas (~800oC) y altos esfuerzos (1-2 Kb), oblitera a la anterior en las zonas de borde de la lámina peridotítica, produciendo la milonitización de las peridotitas y el desarrollo de aureolas dinamotérmicas en los materiales encajantes. Esta deformación se debe al cabalgamiento de una escama del manto sobre la corteza continental. El análisis cinemático de las tectonitas ultrabásicas de alta y baja temperatura proporciona, en la posición actual de las Cordilleras Béticas, una dirección aproximadamente N 70o E para la dirección del "paleo-rift". El cabalgamiento de las peridotitas se ha realizado prácticamente en la misma dirección, desde el WSW hacia el ENE.
