Strength of ties and pioneering orientation: The moderating role of scanning capabilities

The purpose of this article is to study the curvilinear effect on pioneering orientation of one of its key relational backgrounds: strength of ties. The study is based on a sample of 224 companies in the footwear industry in Spain. A hierarchical regression analysis was performed. The results show a curvilinear U-shaped relationship between the strength of ties and pioneering orientation. This curvilinear relationship is increasingly pronounced as scanning capabilities grow. Managers wishing to develop a pioneering orientation should avoid excessive levels of strength in their ties and unduly low levels. Furthermore, firms might benefit from developing scanning capability

Ponencia presentada en: IV Congreso de la Asociación Española de Climatología "El Clima entre el Mar y la Montaña", celebrado en Santander del 2 al 5 de noviembre de 2004.[ES]Se realiza una valoración general de los riesgos climáticos que afectan al solar urbano de Valladolid, diferenciando cómo se manifiestan en los distintos ecótopos de la ciudad. Se evidencia un mayor incremento de la exposición a determinadas situaciones de riesgo en relación con el crecimiento urbano más reciente, el de las dos últimas décadas. Todo ello se sintetiza en un mapa de peligrosidad climática de Valladolid.[EN]This paper undertakes a general assessment of climatic hazards affecting the urban territory of Valladolid across the city's several ecotopes. There is evidence of an increased exposure to certain types of hazard in areas where urban growth has taken place recently, i.e. over the last two decades. Observations are ultimately synthesized in a map showing climatic hazard in the city of Valladolid.Este trabajo se ha realizado en el marco del proyecto de investigación REN2003-01866, financiado por el MCT

Aportaciones sobre cambios en las tendencias de las variables climáticas en la Meseta Central española

El interés creciente por los estudios acerca del Cambio Climático para delimitar y valorar su entidad en diferentes lugares del planeta, así como su evolución a lo largo de las últimas décadas y en un futuro, llevó desde 1997 al desarrollo de una línea de investigación sobre Cambio Climático, dentro del Grupo de Investigación Reconocido de Análisis del Clima de las Universidades de Salamanca (Departamento de Física General y de la Atmósfera) y de Valladolid (Departamento de Geografía), activo en la actualidad. Se presentan los resultados obtenidos de la investigación y producción científica llevada a cabo desde entonces, coincidiendo ahora con el cambio de su investigador principal, D. José Luis Labajo Salazar. El objetivo es mostrar las propuestas metodológicas seguidas a lo largo de estos años en el estudio de variables meteorológicas a partir de las cuales se pueda caracterizar el Cambio Climático en Castilla y León y en toda la meseta central española. Las investigaciones se han centrado en el análisis y modelado de las series temporales de temperaturas, precipitaciones y presión atmosférica a nivel de superficie, empleando técnicas estadísticas y de redes neuronales artificiales. Las aportaciones realizadas en el análisis de sus tendencias, frecuencias, comportamientos de valores extremos y olas de frío y calor, se sintetizan en el presente trabaj

Sutureless colic anastomoses with cyanoacrylates

BACKGROUNO ANO AIMS. The present research Project has been made mainly with the idea of comparing the tensile strength values and histological answers of threetypes of colon anatomises: sutured with silk and sutureless anastomoses with 2-octyl-cyanocrylate and N-butyl-2-cyanoacrylate. Methods. 112 Wistar rats distributed into three groups of 35 animals and a last control group of 7 have been used for this. Group 1: silk, group 2:2-octyl-cyanocrylate, group 3: N-butyl-2-cyanoacrylate,group 4: Control group_. The following surgical interventions were practiced on them:A cross section of the colon,followed by: group 1: an end-to-end discontinuous suture anastomoses with Silk; group 2: sutureless anastomoses with 2-octyl-cyanocrylate;group 3:sutureless anastomoses With N-butyl-2-cyanoar1ylate. On the 10th, 20th, 30th, 40th and 50th days we proceeded to measure the anastomoses tensile strength value for each series.In the same period of time we carried out the following anatomic-pathological determinations: a) sharp inflammation; b) oedema; c) non-specif chronic inflammatory infiltrate; d) granulomatous inflammatory infiltrate to foreign e) fibrosis. Results.The results obtained indicate a greater anastomeses tensile strength for group 2 and 3. The anatomic-pathological values show a better response to anastomoses with adhesive than with conventional sutures. CONCLUSIONS. All these experimental results lead us to conclude that the cyanocrilates used to carry out sutureless anastomoses may be an n alternative to the handmade conventional anastomoses. Moreover they are easy to be implemented

Microdosis de ketamina en la prevención del dolor postoperatorio. Microdoses of ketamine to prevent postoperative pain

A pesar de los conocimientos de la fisiología y la farmacología de los analgésicos y el desarrollo de técnicas más efectivas para el control del dolor postoperatorio aun muchos pacientes sufren dolor. Evaluamos la eficacia de pequeñas dosis de ketamina preoperatoria para prevenir el dolor en el postoperatorio. Se realizó un estudio prospectivo longitudinal, con diseño analítico en el servicio de anestesiología en el Hospital "Abel Santamaría Cuadrado" en el periodo de enero del 2001 a mayo de 2004, la muestra fue de 100 pacientes divididos en 4 grupos de 25 pacientes cada uno, al grupo A se le administró ketamina 0.15 mg/kg 5 minutos antes de la incisión quirúrgica, al finalizar la cirugía se administró 1200 mg de dipirona EV, el grupo B no se administró ketamina solo 1200 mg de dipirona al finalizar la intervención, el grupo C se trató igual que el A pero además se mantuvo con dipirona en infusión 2400 mg a 100 mg/h, el grupo D se administró ketamina previo y dipirona cuando fue necesario. Resulto que la calidad de la analgesia fue significativamente mejor en el grupo C. La diplopia fue el efecto adverso más frecuente en todos los grupos de estudio con 72 % en el grupo A, 88 % el C y 76 % el grupo D. El grado de sedación no fue significativo. La analgesia preventiva con ketamina es un método sencillo que contribuye al alivio del dolor postoperatorio. Palabras clave: ANALGESIA, DOLOR, KETAMINA. ABSTRACT despite knowledge of physiology and pharmacology of pain releivers and the development of more effective techniques to control postoperative pain, many patients still experience pain. Effectiveness of small doses of preoperative betamine was assessed to prevent postoperative pain. A prospective and longitudinal study, with analytical design in the service of anesthesiology at Abel Santamaria Cuadrado Hospital from January, 2001 to May 2004 was performed. The sample comprised 100 patientsdevided into four groups of 25 patients each; group A was administered Ketamine 0.15 mg/kg five minutes before surgical incision. By the end of surgery, 1200mg of endovenous dipyrone was given. Group B was administered Ketamine, just 1200 mg Dipyrone at the end of surgery; group C was treated the same as group A, but, in addition to that, was kept on 2400 mg - 100 mg/h dipyrone infusion; group D was previously administered Ketamine and Dipyrone when necessary. It resulted in Analgesia being significantly better in group C. Diplopia was ther most frequent adverse reaction in all study groups; 72 % group A, 88 % group C, and 76 % group D. the degree of sedation was not significant. Preventive analgesia with Ketamine is a simple method contribuiting to relieve postoperative pain. Key words: ANALGESIA, PAIN, KETAMINe

Laboratory Hyperspectral Image Acquisition System Setup and Validation

Hyperspectral Imaging (HSI) techniques have demonstrated potential to provide useful information in a broad set of applications in different domains, from precision agriculture to environmental science. A first step in the preparation of the algorithms to be employed outdoors starts at a laboratory level, capturing a high amount of samples to be analysed and processed in order to extract the necessary information about the spectral characteristics of the studied samples in the most precise way. In this article, a custom-made scanning system for hyperspectral image acquisition is described. Commercially available components have been carefully selected in order to be integrated into a flexible infrastructure able to obtain data from any Generic Interface for Cameras (GenICam) compliant devices using the gigabyte Ethernet interface. The entire setup has been tested using the Specim FX hyperspectral series (FX10 and FX17) and a Graphical User Interface (GUI) has been developed in order to control the individual components and visualise data. Morphological analysis, spectral response and optical aberration of these pushbroom-type hyperspectral cameras have been evaluated prior to the validation of the whole system with different plastic samples for which spectral signatures are extracted and compared with well-known spectral libraries.Laboratory Hyperspectral Image Acquisition System Setup and ValidationpublishedVersio

City-Friendly Smart Network Technologies and Infrastructures: The Spanish Experience

Efficient, resilient, and sustainable electricity delivery is a key cornerstone in increasingly large and complex urban environments, where citizens expect to keep or rise their living standards. In this context, cost-effective and ubiquitous digital technologies are driving the transformation of existing electrical infrastructures into truly smart systems capable of better providing the services a low-carbon society is demanding. The goal of this paper is twofold: 1) to review the dramatically evolving landscape of power systems, from the old framework based on centralized generation and control, aimed at serving inelastic customers through alternating current (ac) transmission networks and one-way distribution feeders, to a new paradigm centered mainly around two main axes: renewable generation, both centralized and distributed, and active customers (prosumers), interacting with each other through hybrid ac/dc smart grids; 2) to illustrate, through featured success stories, how several smart grid concepts and technologies have been put into practice in Spain over the last few years to optimize the performance of urban electrical assets
