One Thousand and One Bubbles

We propose a novel strategy that permits the construction of completely general five-dimensional microstate geometries on a Gibbons-Hawking space. Our scheme is based on two steps. First, we rewrite the bubble equations as a system of linear equations that can be easily solved. Second, we conjecture that the presence or absence of closed timelike curves in the solution can be detected through the evaluation of an algebraic relation. The construction we propose is systematic and covers the whole space of parameters, so it can be applied to find all five-dimensional BPS microstate geometries on a Gibbons-Hawking base. As a first result of this approach, we find that the spectrum of scaling solutions becomes much larger when non-Abelian fields are present. We use our method to describe several smooth horizonless multicenter solutions with the asymptotic charges of three-charge (Abelian and non-Abelian) black holes. In particular, we describe solutions with the centers lying on lines and circles that can be specified with exact precision. We show the power of our method by explicitly constructing a 50-center solution. Moreover, we use it to find the first smooth five-dimensional microstate geometries with arbitrarily small angular momentum.Comment: 33 pages. v2: typos correcte

The growth of galactic bulges through mergers in LCDM haloes revisited. II. Morphological mix evolution

The mass aggregation and merger histories of present-day distinct haloes selected from the cosmological Millennium Simulations I and II are mapped into stellar mass aggregation and galaxy merger histories of central galaxies by using empirical stellar-to-halo and stellar-to-gas mass relations. The growth of bulges driven by the galaxy mergers/interactions is calculated using dynamical prescriptions. The predicted bulge demographics at redshift z~0 is consistent with observations (Zavala+2012). Here we present the evolution of the morphological mix (traced by the bulge-to-total mass ratio, B/T) as a function of mass up to z=3. This mix remains qualitatively the same up to z~1: B/T<0.1 galaxies dominate at low masses, 0.1<B/T<0.45 at intermediate masses, and B/T>0.45 at large masses. At z>1, the fractions of disc-dominated and bulgeless galaxies increase strongly, and by z~2 the era of pure disc galaxies is reached. Bulge-dominated galaxies acquire such a morphology, and most of their mass, following a downsizing trend. Since our results are consistent with most of the recent observational studies of the morphological mix at different redshifts, a LCDM-based scenario of merger-driven bulge assembly does not seem to face critical issues. However, if the stellar-to-halo mass relation changes too little with redshift, then some tensions with observations appear.Comment: 16 pages, 11 figures. Accepted for publication in MNRAS.

The custom-made foot orthosis using the Central Stabilizer Element: nex concept of element

Foot orthoses have been applied for the management of lower limb disorders, mainly for those who develop foot pain. The Central Stabilizer Element (CSE) is a new element that contains the midfoot laterally when a plantar insole is manufactured. OBJECTIVES: - To determine the effect on foot pain of adding the Central Stabilizer Element during the manufacturing process of foot orthosis, -- - To describe the proportions of Central Stabilizer Element in terms of width and length of this element. METHODS: A sample comprising 130 patients (57 males and 73 females) with foot pain was recruited for this study, with the patients having supinated, neutral, pronated and overpronated feet. All the patients received a custom-made foot orthosis with the Central Stabilizer Element. The Central Stabilizer Element was made of resins of polyvinyl chloride, and is a device insert in foot orthosis that contains the midfoot laterally to control pronation and supination movements. Conclusion •The students know how to design the insole. •They know how to match different foot posture with the different types of insoles •We make our decisions based on the scientific evidence foundUniversidad de Málaga.

Caracterización del consumidor de productos orgánicos en la ciudad de Toluca, Méx.

México, es un importante productor de alimentos orgánicos, sin embargo el consumo de éstos entre su población es solamente del 15% de la producción, y de éste únicamente el 5% se comercializa como Producto Orgánico (PO) mientras que el restante 10% se comercializa como producto convencional. Entre otras razones que se presentan para el bajo consumo son: la difusa ubicación en el punto de venta; la baja inversión por parte de los productores para la difusión e identificación del concepto orgánico así como los beneficios que otorgan. Dado que la comercialización de productos orgánicos manifiesta un desarrollo endógeno y día a día cobra auge hacia la exportación, el presente trabajo tiene como objetivo determinar las características de los consumidores de productos orgánicos en la Cd. de Toluca, Méx., a través de un análisis de los resultados de la aplicación de encuestas. La investigación se llevó a cabo en tres etapas: 1) Investigación documental, 2) Aplicación de encuesta, 3) Análisis de resultados. Se aplicaron 386 encuestas de enero a marzo del 2011; para tipificar al consumidor final de PO, que tiene las siguientes características: un rango de edad de 24 a 35años, la decisión de comprar depende del género femenino, con un nivel de estudios superior, empleados y de Nivel Socio Económico (NSE) C+; la tendencia de consumo presenta un 44% , las variables que influyen en el consumo son: productos costosos, desconocimiento de los beneficios y difíciles de encontrar en el mercado, son preferidos a los productos convencionales por ser considerados productos saludables y en fresco, el consumidor los reconoce por el empaque y el sello de certificación, las compras se realizan semanalmente con gasto entre $200.00-$500.00

Neuronal Models for Studying Tau Pathology

Alzheimer's disease (AD) is the most frequent neurodegenerative disorder leading to dementia in the aged human population. It is characterized by the presence of two main pathological hallmarks in the brain: senile plaques containing β-amyloid peptide and neurofibrillary tangles (NFTs), consisting of fibrillar polymers of abnormally phosphorylated tau protein. Both of these histological characteristics of the disease have been simulated in genetically modified animals, which today include numerous mouse, fish, worm, and fly models of AD. The objective of this review is to present some of the main animal models that exist for reproducing symptoms of the disorder and their advantages and shortcomings as suitable models of the pathological processes. Moreover, we will discuss the results and conclusions which have been drawn from the use of these models so far and their contribution to the development of therapeutic applications for AD
