Estrategia y gestión de la marca Sti-Bataná

Durante este proyecto se buscó principalmente ayudar a la marca a crecer su cartera de clientes, aumentar el alcance de visualización de la marca, definir la personalidad, estructura y objetivos de la empresa, lograr formalizarla un poco más y también ayudar con el branding de la marca. A lo largo de este proyecto estuvimos trabajando con las redes sociales y las bases de la cultura organizacional de la empresa. En ello se realizaron trabajos como toma y edición de fotografías y por otro lado la reformular y plantear la misión, visión, propuesta de valor y objetivos de la marca como empresa. También estuvimos realizando acciones de marketing para ayudar a que la marca tuviera más alcance en cuanto a seguidores y más interacciones y para ello establecimos un plan de trabajo para que una vez concluido nuestro trabajo, se continúe con un esquema de publicaciones tales como subir una historia, un reel o una foto acompañado de alguna acción con ciertas palabras.ITESO, A.C

Agentes infecciosos de Litopenaeus vannamei (Boone, 1931) y su relación con parámetros físicoquímicos de tres diferentes sistemas de cultivo en el golfo de México.

La producción de camarón aumentó de 33.480 toneladas por año en 2000-2001 a 128 000 t en el período 2008-2009, lo que representa el 69% de la producción total en México. Se colectaron muestras de L. vannamei desde 2008 hasta 2009, durante dos ciclos de producción de tres granjas de camarón en el estado de Tamaulipas. Durante el ciclo 2009, se analizaron un total de 600 organismos; 180 de Reynosa, 180 de La Pesca, y 240 de Morón. Se midio el oxígeno disuelto (OD, mg/L) y la temperatura (°C) dos veces al día (mañana y noche). La salinidad, el pH y la turbidez del agua se midieron diariamente. Durante el ciclo de cultivo del 2008, un total de 660 organismos fueron muestreados. Este estudio representa el primer registro geográfico de la presencia de L. mucor, Zoothamnium sp, Epistylis sp, Acineta sp y Nematopsis sp en L. vannamei de piscifactorías en Tamaulipas

Attitudes and burden in relatives of patients with schizophrenia in a middle income country

BACKGROUND: Most studies of family attitudes and burden have been conducted in developed countries. Thus it is important to test the generalizability of this research in other contexts where social conditions and extended family involvement may be different. The aim of this study was to assess the relationship between the attitudes of caregivers and the burden they experience in such a context, namely Arica, a town located in the northernmost region of Chile, close to the border with Peru and Bolivia. METHODS: We assessed attitudes towards schizophrenia (including affective, cognitive and behavioural components) and burden (including subjective distress, rejection and competence) in 41 main caregivers of patients with schizophrenia, all of whom were users of Public Mental Health Services in Arica. RESULTS: Attitude measures differed significantly according to socio-demographic variables, with parents (mainly mothers) exhibiting a more negative attitude towards the environment than the rest of the family (t = 4.04; p = 0.000).This was also the case for caregivers with a low educational level (t = 3.27; p < 0.003), for the oldest caregivers (r = 0.546; p = 0.000) and for those who had spent more time with the patient (r = 0.377; p = 0.015). Although attitudes had significant association with burden, their explanatory power was modest (R2 = .104, F = 4,55; p = .039). CONCLUSIONS: Similar to finding developed countries, the current study revealed a positive and significant relationship between the attitudes of caregivers and their burden. These findings emphasize the need to support the families of patients with schizophrenia in this social context

Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory

Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this part of the sky is already significantly larger than that of the fore-runner experiments. Our results do not support previous findings of localized excesses in the AGASA and SUGAR data. We set an upper bound on a point-like flux of cosmic rays arriving from the Galactic Centre which excludes several scenarios predicting sources of EeV neutrons from Sagittarius $A$. Also the events detected simultaneously by the surface and fluorescence detectors (the `hybrid' data set), which have better pointing accuracy but are less numerous than those of the surface array alone, do not show any significant localized excess from this direction.Comment: Matches published versio

The Fluorescence Detector of the Pierre Auger Observatory

The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays. It combines a surface array to measure secondary particles at ground level together with a fluorescence detector to measure the development of air showers in the atmosphere above the array. The fluorescence detector comprises 24 large telescopes specialized for measuring the nitrogen fluorescence caused by charged particles of cosmic ray air showers. In this paper we describe the components of the fluorescence detector including its optical system, the design of the camera, the electronics, and the systems for relative and absolute calibration. We also discuss the operation and the monitoring of the detector. Finally, we evaluate the detector performance and precision of shower reconstructions.Comment: 53 pages.

Atmospheric effects on extensive air showers observed with the Surface Detector of the Pierre Auger Observatory

Atmospheric parameters, such as pressure (P), temperature (T) and density, affect the development of extensive air showers initiated by energetic cosmic rays. We have studied the impact of atmospheric variations on extensive air showers by means of the surface detector of the Pierre Auger Observatory. The rate of events shows a ~10% seasonal modulation and ~2% diurnal one. We find that the observed behaviour is explained by a model including the effects associated with the variations of pressure and density. The former affects the longitudinal development of air showers while the latter influences the Moliere radius and hence the lateral distribution of the shower particles. The model is validated with full simulations of extensive air showers using atmospheric profiles measured at the site of the Pierre Auger Observatory.Comment: 24 pages, 9 figures, accepted for publication in Astroparticle Physic
