Estrategias de mercadeo online para el lanzamiento de la marca Rio Technology® en Colombia

RIO TECHNOLOGY SAS es una empresa que lleva 11 años en el mercado de la distribución al por mayor de tecnología a todo nivel y suministros para oficina en Bogotá y en algunas otras ciudades del país. Fue constituida formalmente en el año 2001 ante la cámara de comercio de Bogotá como una sociedad anónima, y en el año 2010 cambió su tipo de sociedad, y se convirtió en sociedad por acciones simplificada, aprovechando los beneficios que este tipo de sociedad comercial brinda a las empresas medianas y pequeñas en Colombia. La idea de este proyecto nace porque desde Julio del año 2013, la marca RIO® se encuentra registrada, lo que genera grandes inquietudes acerca del cómo poder aprovechar esta situación para que la empresa RIO TECHNOLOGY se dé a conocer en el mercado y lograr un mayor crecimiento de la misma mediante la promoción y fortalecimiento de su marca, generando mayores utilidades. El mercadeo online podría ser una excelente alternativa para lanzar la marca RIO® al mercado; usando las redes sociales, por ejemplo, pues estas han sido creadas para conectar personas, grupos, páginas, etc. Y además son un medio de comunicación muy efectivo, por lo que la empresa RIO TECHNOLOGY podría estar en contacto permanente y cercano con sus clientes, dando a conocer en todo momento su marca RIO® mediante estrategias promocionales. En la actualidad, las redes sociales han significado una gran oportunidad tanto para las grandes empresas como para las Pymes; pues por medio de ellas se llega a una gran cantidad de personas en cuestión de segundos, con lo cual, usando estrategias eficientes, se logran resultados potenciales que se ven reflejados en un fortalecimiento de marca. El objetivo de este proyecto es presentar a RIO TECHNOLOGY un plan estratégico de mercadeo online para lanzar y fortalecer su marca. Se busca que la empresa mejore potencialmente el nivel de sus ventas y comience a posicionar su marca en el mercado.

Post-dispersal seed predation of non-target weeds in arable crops

Field experiments were conducted to quantify the natural levels of post-dispersal seed predation of arable weed species in spring barley and to identify the main groups of seed predators. Four arable weed species were investigated that were of high biodiversity value, yet of low to moderate competitive ability with the crop. These were Chenopodium album, Sinapis arvensis, Stellaria media and Polygonum aviculare. Exclusion treatments were used to allow selective access to dishes of seeds by different predator groups. Seed predation was highest early in the season, followed by a gradual decline in predation over the summer for all species. All species were taken by invertebrates. The activity of two phytophagous carabid genera showed significant correlations with seed predation levels. However, in general carabid activity was not related to seed predation and this is discussed in terms of the mainly polyphagous nature of many Carabid species that utilized the seed resource early in the season, but then switched to carnivory as prey populations increased. The potential relevance of post-dispersal seed predation to the development of weed management systems that maximize biological control through conservation and optimize herbicide use, is discussed.

Knowledge-based clinical pathway for medical quality improvement

Clinical pathways have been adopted for various diseases in clinical departments for quality improvement as a result of standardization of medical activities in treatment process. Using knowledge-based decision support on the basis of clinical pathways is a promising strategy to improve medical quality effectively. However, the clinical pathway knowledge has not been fully integrated into treatment process and thus cannot provide comprehensive support to the actual work practice. Therefore this paper proposes a knowledgebased clinical pathway management method which contributes to make use of clinical knowledge to support and optimize medical practice. We have developed a knowledgebased clinical pathway management system to demonstrate how the clinical pathway knowledge comprehensively supports the treatment process. The experiences from the use of this system show that the treatment quality can be effectively improved by the extracted and classified clinical pathway knowledge, seamless integration of patient-specific clinical pathway recommendations with medical tasks and the evaluating pathway deviations for optimization.

Simulação do escoamento monofásico em um estágio de uma bomba centrífuga utilizando técnicas de fluidodinâmica computacional

Oil production and exploration techniques have evolved in the last decades in order to increase fluid flows and optimize how the required equipment are used. The base functioning of Electric Submersible Pumping (ESP) lift method is the use of an electric downhole motor to move a centrifugal pump and transport the fluids to the surface. The Electric Submersible Pumping is an option that has been gaining ground among the methods of Artificial Lift due to the ability to handle a large flow of liquid in onshore and offshore environments. The performance of a well equipped with ESP systems is intrinsically related to the centrifugal pump operation. It is the pump that has the function to turn the motor power into Head. In this present work, a computer model to analyze the three-dimensional flow in a centrifugal pump used in Electric Submersible Pumping has been developed. Through the commercial program, ANSYS® CFX®, initially using water as fluid flow, the geometry and simulation parameters have been defined in order to obtain an approximation of what occurs inside the channels of the impeller and diffuser pump in terms of flow. Three different geometry conditions were initially tested to determine which is most suitable to solving the problem. After choosing the most appropriate geometry, three mesh conditions were analyzed and the obtained values were compared to the experimental characteristic curve of Head provided by the manufacturer. The results have approached the experimental curve, the simulation time and the model convergence were satisfactory if it is considered that the studied problem involves numerical analysis. After the tests with water, oil was used in the simulations. The results were compared to a methodology used in the petroleum industry to correct viscosity. In general, for models with water and oil, the results with single-phase fluids were coherent with the experimental curves and, through three-dimensional computer models, they are a preliminary evaluation for the analysis of the two-phase flow inside the channels of centrifugal pump used in ESP systems

Implementação de um sistema embarcado aplicado ao controle de pressão arterial

Hypertension is a dangerous disease that can cause serious harm to a patient health. In some situations the necessity to control this pressure is even greater, as in surgical procedures and post-surgical patients. To decrease the chances of a complication, it is necessary to reduce blood pressure as soon as possible. Continuous infusion of vasodilators drugs, such as sodium nitroprusside (SNP), rapidly decreased blood pressure in most patients, avoiding major problems. Maintaining the desired blood pressure requires constant monitoring of arterial blood pressure and frequently adjusting the drug infusion rate. Manual control of arterial blood pressure by clinical personnel is very demanding, time consuming and, as a result, sometimes of poor quality. Thus, the aim of this work is the design and implementation of a database of tuned controllers based on patients models, in order to find a suitable PID to be embedded in a Programmable Integrated Circuit (PIC), which has a smaller cost, smaller size and lower power consumption. For best results in controlling the blood pressure and choosing the adequate controller, tuning algorithms, system identification techniques and Smith predictor are used. This work also introduces a monitoring system to assist in detecting anomalies and optimize the process of patient care.

Utilizando mapas de conectividade fuzzy no desenvolvimento de algoritmos reparadores de imagens binárias 3D

A 3D binary image is considered well-composed if, and only if, the union of the faces shared by the foreground and background voxels of the image is a surface in R3. Wellcomposed images have some desirable topological properties, which allow us to simplify and optimize algorithms that are widely used in computer graphics, computer vision and image processing. These advantages have fostered the development of algorithms to repair bi-dimensional (2D) and three-dimensional (3D) images that are not well-composed. These algorithms are known as repairing algorithms. In this dissertation, we propose two repairing algorithms, one randomized and one deterministic. Both algorithms are capable of making topological repairs in 3D binary images, producing well-composed images similar to the original images. The key idea behind both algorithms is to iteratively change the assigned color of some points in the input image from 0 (background)to 1 (foreground) until the image becomes well-composed. The points whose colors are changed by the algorithms are chosen according to their values in the fuzzy connectivity map resulting from the image segmentation process. The use of the fuzzy connectivity map ensures that a subset of points chosen by the algorithm at any given iteration is the one with the least affinity with the background among all possible choices

Contaminação da pastagem com larvas infectantes de nematoides gastrintestinais após o pastejo de ovelhas resistentes ou susceptíveis à verminose

O grau de contaminação da pastagem por larvas de terceiro estágio (L3) de nematoides gastrintestinais foi avaliado em piquetes pastejados por ovelhas resistentes ou susceptíveis à verminose. O experimento foi realizado de 23 de novembro de 2007 a 22 de julho de 2008. Inicialmente, realizou-se a contagem de ovos por grama de fezes (OPG) de amostras individuais de 130 ovelhas adultas da raça Bergamácia. Dessas, foram selecionadas as nove ovelhas com contagens mais elevadas de OPG (susceptíveis) e as 10 com as menores contagens (resistentes). As ovelhas resistentes apresentaram menor contagem de OPG, maiores valores de volume globular, de proteína plasmática total e de eosinófilos sanguíneos, do que as ovelhas susceptíveis. O peso também foi maior no grupo resistente. Na pastagem, foram identificadas larvas de Haemonchus spp., Trichostrongylus spp. e Oesophagostomum spp. em média, as quantidades de L3 de Haemonchus spp. e de Trichostrongylus spp., na pastagem, foram 2,19 e 2,31 vezes, respectivamente, maiores nos piquetes pastejados pelo grupo susceptível do que nos do grupo resistente. Portanto, os animais susceptíveis devem ser eliminados do rebanho a fim de reduzir a contaminação da pastagem e otimizar a profilaxia das infecções por nematoides gastrintestinais.

Detection of propranolol in pharmaceutical formulations by diffuse reflectance spectroscopy

This paper describes an analytical reflectometric method that has an objective not only the industrial quality control but also to detect possible falsifications and/or adulterations of propranolol in pharmaceutical formulations. The method is based on the diffuse reflectance measurements of the colored product (III) of the spot test reaction between propranolol hydrochloride (I) and 2,6-dichloroquinone-4-chloroimide (II) using filter paper as solid support. Spot test conditions have been investigated using experimental design in order to identify and optimize the critical factors. The factors evaluated were DCQ concentration, propranolol solvent and DCQ solvent. The best reaction conditions were achieved with the addition of 30 mu L, of propranolol solution in ethanol 35% (v/v) and 30 mu L of DCQ solution at 70 mg mL(-1) in acetone, in this order. All reflectance measurements were carried out at 500 nm and the linear range was from 8.45 x 10(-4) to 8.45 x 10(-2) mol L-1 (r= 0.998). The limit of detection was 1.01 x 10(-4) mol L-1. No interference was observed from the assessed excipients and drugs. The method was applied to determine propranolol in commercial brands of pharmaceuticals. The results obtained by the proposed method were favorably compared with those given by the British Pharmacopoeia procedure. (C) 2007 Elsevier B.V. All rights reserved.
