Variaciones estacionales en la gestión del pastoreo en una explotación caprina lechera de un área de monta a mediterránea
Blanco Sepúlveda, R.
Pirineos : Revista de Ecología de Monta？a , 2001,
Abstract: The analysis of the grazing management is one of the most important topic among the studies of space plannification for livestock use. The grazing management of a dairy goat farm is analized with the objective of characterizing the seasonal variations happened along the year. Have been used three parameters to analyze the management: grazing period, grazing distance and grazing speed. The obtained results show the existence of a marked seasonal variability in the grazing management, phenomenon correlated with the intraanual climatic variability of the mediterranean area. [fr] L'analyse de la gestion du paturage est une des plus importantes thématiques dans les études de l'organisation de l'espace pour l'usage du bétail. Dans ce travail, on analyse la gestion du paturage d'une ferme-laiterie caprine, avec l'objectif de caractériser les variations saisonnières annuelles. Trois paramètres ont été utilisés pour analyser la gestion: la journée de paturage, la longueur du parcours et la vitesse du parcours. Les résultats obtenus montrent l'existence d'une variabilité saisonnière marquée dans la gestion du paturage, le phénomène est en relation avec la variabilité climatique intra-annuelle de l'environnement méditerranéen. [es] El análisis de la gestión del pastoreo es una de las temáticas de trabajo más importantes dentro de los estudios de planificación del espacio para uso ganadero. En este trabajo se analiza la gestión de pastoreo de una explotación caprina lechera con el objetivo de caracterizar las variaciones estacionales que se suceden a lo largo del a o. Se han utilizado tres parámetros para analizar la gestión: duración de la jornada de pastoreo, longitud de los itinerarios y velocidad de pastoreo. Los resultados obtenidos ponen de manifiesto la existencia de una marcada variabilidad estacional en la gestión del pastoreo, fenómeno que se relaciona con la variabilidad climática intraanual de los ambientes de clima mediterráneo.

Revisión teórica de los factores culturales organizacionales y psicosociales para una implantación exitosa de empresas extranjeras en México
González, R.,Blanco, M
Innovaciones de Negocios , 2012,
Abstract: Cuando las empresas extranjeras se implantan en un nuevo país, surgen diferencias culturales que afectan la productividad de los empleados. Tanto los empleados extranjeros como los locales no están ajenos a los efectos psicológicos ocasionados por el choque cultural y su consecuente pérdida de productividad, principalmente durante la etapa de arranque de las operaciones. Existen estudios sobre los diferentes factores del ámbito psicológico que afectan de manera negativa la productividad en las empresasy factores culturales organizacionales que tienen un impacto en la implantacion de estas empresas. Por lo que es evidente y posible la generación de un choque cultural en empresas extranjeras operando en territorio Mexicano. En este caso se busca con este artículo realizar una revisión teórica sobre la relación que existe entre el nivel del choque cultural que se genera en la interacción de empleados de diferentes culturas y/o nacionalidades, y analizar teóricamente los factores culturales organizacionales y psicológicos que pueden afectar el buen desempe o del empleado para ser tomados en cuenta por la gerencia de las empresas extranjeras implantadas en México, para minimizar el efecto negativo sobre la eficiencia organizacional.
2D-Oide effect
O. R. Blanco,R. Tomas,P. Bambade
Physics , 2015,
Abstract: The Oide effect considers the synchrotron radiation in the final focusing quadrupole and it sets a lower limit on the vertical beam size at the Interaction Point, particularly relevant for high energy linear colliders. The theory of the Oide effect was derived considering only the radiation in the focusing plane of the magnet. This article addresses the theoretical calculation of the radiation effect on the beam size consider- ing both focusing and defocusing planes of the quadrupole, refered to as 2D-Oide. The CLIC 3 TeV final quadrupole (QD0) and beam parameters are used to compare the theoretical results from the Oide effect and the 2D-Oide effect with particle tracking in PLACET. The 2D-oide demonstrates to be important as it increases by 17% the contribution to the beam size. Further insight into the aberrations induced by the synchrotron radiation opens the possibility to partially correct the 2D-Oide effect with octupole magn
LA VARIACIóN ANUAL DE LOS áNGULOS SOLARES EN LA LATITUD DE SANTA MARTA Y SU IMPORTANCIA LOCAL
Blanco R.,Jacobo; Pérez,Elíseo;
Boletín de Investigaciones Marinas y Costeras - INVEMAR , 2009,
Abstract: annual changes on the sun's apparent bearing (azimuth) and on its relative height on the sky, expressed as altitude and declination for santa marta's latitude, are analyzed. observed azimuth data did not differ significantly from those calculated. local daylight duration in minutes was also computed. the parameters for a predictive model as a function of the day's number and their c. i. at 95 % are estimated. because of its mountainous topography, the santa marta region shows areas where sunlight availability changes throughout the year due to their northern or southern location of promontories and to the respective solar angles. implications for local living communities are discussed.

Abstract: Pelvic and intra-abdominal Actinomycosis can be difficult to diagnose preoperatively and it may also mimic many other diseases, including malignancies. We present a patient with pelvic Actinomycosis probably caused by a long-standing intrauterine device (IUD). We emphasize the challenges in diagnostic process and stress that though a rare disease, intra-abdominal Actinomycosis should be suspected in cases with intra-abdominal mass of uncertain etiology. The early recognition may spare the patient from extensive surgical operation. 1. Introduction Pelvic Actinomycosis is a rare disease with poorly understood pathogenesis. It commonly occurs in women with an intrauterine device of prolonged duration. Actinomyces are Gram-positive anaerobic bacteria that are normal inhabitants of the mouth and bowel. The organism only penetrates mucosal barrier after a tissue injury [1]. Early diagnosis of abdominal Actinomycosis is of importance, as timely recognition enables conservative treatment with antibiotics, avoiding surgery [2]. There is no documented person-to-person transmission of the disease [3]. 2. Case Report Our own case is a 45-year-old woman, who was referred to surgical ward due to an intestinal occlusion and tumor-like mass in the region of flexura lienalis. The patient had no preceding chronic disease or constant medication. She complained of increasing lower abdominal discomfort for 6 months with diarrhea and constipation. Abdominal native radiographs suggested occlusion (Figure 1). Laboratory parameters showed an increased thrombocyte count (689 × 109/L) and a mild decrease of hemoglobin value (107？g/L). Other laboratory parameters including C-reactive protein, leukocytes, CEA, CA 12-5, and CA 19-9 were normal. She had no weight loss or fever. A contrast-enhanced (i.v.) 16-detector row helical pelvic CT scan was performed (Figure 2). Bowel contrast was not used. CT showed dilated colon (maximal diameter 8？cm) and, distal to this, a narrowed colon segment at flexura lienalis, presenting as a probable cause of occlusion. There was tissue infiltration surrounding the bowel stricture as well as separate omental infiltration proximal and distal to the obstruction site. Peritoneal fat stranding, indicating edema, was present surrounding the abnormal bowel segments and there was an enhancing cystic lesion (diameter 4.5？cm) in the right ovary. There were also increased number of lymph nodes in paraaortil space and omentum. Malignancy could not be equivocally excluded. Because of a tumor-like mass and prolonged intensive occlusion lasting for 10 days, a
A new method to measure the CP violating angle gamma using B^\pm -> pi^\pm pi^+ pi^- and B^\pm -> K^\pm pi^+ pi^- decays

Abstract: A new and simple procedure to measure the angle $\gamma$ from $B^{\pm} \to \pi^{\pm}\pi^+\pi^-$ and $B^{\pm} \to K^{\pm}\pi^+\pi^-$ decays using SU(3) symmetry is presented. It is based on a full Dalitz plot analysis of these decays. All diagrams, including strong and electroweak penguins, are considered in the procedure. The method is also free from final state interaction problems. The theoretical error in the extraction of $\gamma$ within the method should be of the order of $10^{\rm o}$ or even less. Taking into account the B-meson production in the first generation of B factories and recent measurements from CLEO, this method could bring the best measurement of $\gamma$ in the next years.
