“NIVEL DE INFORMACIÓN DE LOS MÉDICOS PASANTES DE SERVICIO SOCIAL DE LA UNIVERSIDAD AUTÓNOMA DEL ESTADO DE MÉXICO SOBRE LA IMPORTANCIA DE LA TERAPIA FÍSICA EN EL TRATAMIENTO DE PACIENTES CON DIABETES MELLITUS TIPO 2, 2013.”
La diabetes mellitus es un desorden metabólico de múltiples etiologías que resulta de defectos en la secreción o acción de la insulina, se caracteriza por hiperglucemia crónica con disturbios en el metabolismo de carbohidratos, grasas y proteínas. Sus síntomas clásicos son: poliuria, polidipsia, polifagia, pérdida de peso. Existen diversos factores de riesgo para padecer esta enfermedad como lo son: sobrepeso, obesidad, sedentarismo, familiares de primer grado con diabetes, hipertensión arterial, dislipidemia y enfermedades cardiovasculares, entre otras. Ya que esta enfermedad es reconocida como una amenaza mundial y se estima que las cifras sigan aumentando en los próximos años, es de gran importancia tomar medidas preventivas para evitar la aparición o progresión de la enfermedad
Understanding collaboration in Global Software Engineering (GSE) teams with the use of sensors: introducing a multi-sensor setting for observing social and human aspects in project management
This paper discusses on-going research in the ways Global Software Engineering (GSE) teams collaborate for a range of software development tasks. The paper focuses on providing the means for observing and understanding GSE team member collaboration including team coordination and member communication. Initially the paper provides the background on social and human issues relating to GSE collaboration. Next the paper describes a pilot study involving a simulation of virtual GSE teams working together with the use of asynchronous and synchronous communication over a virtual learning environment. The study considered the use of multiple data collection techniques recordings of SCRUM meetings, design and implementation tasks. Next, the paper discusses the use of a multi-sensor for observing human and social aspects of project management in GSE teams. The scope of the study is to provide the means for gathering data regarding GSE team coordination for project managers including member emotions, participation pattern in team discussions and potentially stress levels
Quantum Inconsistency of Einstein Supergravity
We show that N=1, D=4 Einstein-frame supergravity is inconsistent at one loop
because of an anomaly in local supersymmetry transformations. A Jacobian must
be added to the Einstein-frame Lagrangian to cancel this anomaly. We show how
the Jacobian arises from the super-Weyl field redefinition that takes the
superspace Lagrangian to the Einstein frame. We present an explicit example
which demonstrates that the Jacobian is necessary for one-loop scattering
amplitudes to be frame independent.Comment: 16 pages, One figure, Latex. Published versio
Elastic turbulence in shear banding wormlike micelles
We study the dynamics of the Taylor-Couette flow of shear banding wormlike
micelles. We focus on the high shear rate branch of the flow curve and show
that for sufficiently high Weissenberg numbers, this branch becomes unstable.
This instability is strongly sub-critical and is associated with a shear stress
jump. We find that this increase of the flow resistance is related to the
nucleation of turbulence. The flow pattern shows similarities with the elastic
turbulence, so far only observed for polymer solutions. The unstable character
of this branch led us to propose a scenario that could account for the recent
observations of Taylor-like vortices during the shear banding flow of wormlike
micelles

Perturbations and quasi-normal modes of black holes in Einstein-Aether theory
We develop a new method for calculation of quasi-normal modes of black holes,
when the effective potential, which governs black hole perturbations, is known
only numerically in some region near the black hole. This method can be applied
to perturbations of a wide class of numerical black hole solutions. We apply it
to the black holes in the Einstein-Aether theory, a theory where general
relativity is coupled to a unit time-like vector field, in order to observe
local Lorentz symmetry violation. We found that in the non-reduced
Einstein-Aether theory, real oscillation frequency and damping rate of
quasi-normal modes are larger than those of Schwarzschild black holes in the
Einstein theory.Comment: 6 pages, 3 figures, RevTex, to be published in Phys. Lett.
Stability of multidimensional black holes: complete numerical analysis
We analyze evolution of gravitational perturbations of D-dimensional
Schwarzschild, Reissner-Nordstr\"om, and Reissner-Nordstrom-de Sitter black
holes. It is known that the effective potential for the scalar type of
gravitational perturbations has negative gap near the event horizon. This gap,
for some values of the parameters Q (charge), Lambda (cosmological constant)
and D (number of space-time dimensions), cannot be removed by S-deformations.
Thereby, there is no proof of (in)stability for those cases. In the present
paper, by an extensive search of quasinormal modes, both in time and frequency
domains, we shall show that spherically symmetric static black holes with
arbitrary charge and positive (de Sitter) lambda-term are stable for D=5, 6,
>...11. In addition, we give a complete numerical data for all three types
(scalar, vector and tensor) of gravitational perturbations for
multi-dimensional black holes with charge and Lambda-term. The influence of
charge, Lambda-term and number of extra dimensions on black hole quasinormal
spectrum is discussed.Comment: 12 pages, RevTe
