On the Stability of Black Holes at the LHC
The eventual production of mini black holes by proton-proton collisions at
the LHC is predicted by theories with large extra dimensions resolvable at the
Tev scale of energies. It is expected that these black holes evaporate shortly
after its production as a consequence of the Hawking radiation. We show that
for theories based on the ADS/CFT correspondence, the produced black holes may
have an unstable horizon, which grows proportionally to the square of the
distance to the collision point.Comment: 3 page
Dynamical aspects of Kinouchi-Copelli model: emergence of avalanches at criticality
We analyze the behavior of bursts of neural activity in the Kinouchi-Copelli
model, originally conceived to explain information processing issues in sensory
systems. We show that, at a critical condition, power-law behavior emerges for
the size and duration of the bursts (avalanches), with exponents experimentally
observed in real biological systems.Comment: Paper accepted for Brazilian Conference on Dynamics, Control and

Duality and interval analysis over idempotent semirings
In this paper semirings with an idempotent addition are considered. These
algebraic structures are endowed with a partial order. This allows to consider
residuated maps to solve systems of inequalities . The
purpose of this paper is to consider a dual product, denoted , and the
dual residuation of matrices, in order to solve the following inequality . Sufficient conditions ensuring the
existence of a non-linear projector in the solution set are proposed. The
results are extended to semirings of intervals
An alternative theoretical approach to describe planetary systems through a Schrodinger-type diffusion equation
In the present work we show that planetary mean distances can be calculated
with the help of a Schrodinger-type diffusion equation. The obtained results
are shown to agree with the observed orbits of all the planets and of the
asteroid belt in the solar system, with only three empty states. Furthermore,
the equation solutions predict a fundamental orbit at 0.05 AU from solar-type
stars, a result confirmed by recent discoveries. In contrast to other similar
approaches previously presented in the literature, we take into account the
flatness of the solar system, by considering the flat solutions of the
Schrodinger-type equation. The model has just one input parameter, given by the
mean distance of Mercury.Comment: 6 pages. Version accepted for publication in Chaos, Solitons &

Implications of Vestibular Dysfunction Among the Aging Population: A Pocket Guide for Health Care Professionals
The goal of this health information booklet is to provide healthcare professionals with the appropriate tools and information required to ensure all patients with a vestibular impairment are cared for and treated appropriately. The following guide includes overview of the vestibular system, vestibulotoxic medications, and common vestibular disorders. These notable areas are required for appropriate treatment and referral to other professionals for treatment

Primary Care Rotation – Pediatric Resident´s Opinion
Introdução: O Estágio em Cuidados de Saúde Primários à Criança e ao Adolescente foi integrado no programa do Internato
Complementar de Pediatria em 1996. Desde então, não foi revisto, apesar de vários aspectos relativos à sua realização
suscitarem controvérsia.
Objectivos: Conhecer a opinião dos internos relativamente ao estágio e, deste modo, contribuir para a revisão do programa de formação, em curso.
Metodologia: Estudo transversal descritivo com aplicação de um questionário por via electrónica, aos internos de Pediatria
e recém-especialistas, incidindo sobre três questões: parecer geral sobre o estágio actualmente preconizado, caracterização e opinião sobre o estágio realizado e perspectivas para o futuro.
Resultados: Foram obtidas 68 respostas; 62/68 (91%) dos inquiridos concordam com a realização do estágio, mas 58/68 (85%) consideram-no demasiado longo e 18/68 (25%) pouco útil; 46/68 (68%) observaram crianças/adolescentes sem médico assistente atribuído e 36/68 (44%) consideram que o estágio foi maioritariamente não tutelado. Os aspectos positivos referidos foram a possibilidade de fazer a consulta de vigilância de forma longitudinal e de conhecer a realidade dos
cuidados de saúde primários assim como o contacto com a saúde escolar e com a comunidade da criança. Os aspectos
negativos incluíram a duração excessiva, a orientação inadequada, a ausência de um estágio estruturado e a má definição
do papel do interno.
Conclusões: O grau de insatisfação com o Estágio em Cuidados de Saúde Primários à Criança e ao Adolescente foi elevado,
ficando clara a necessidade de instituir modificações relativamente à duração, programa e orientação do estágio.
Com base nas opiniões dos inquiridos, é apresentado um conjunto de propostas para a reformulação do estágio
