Revista de la Sociedad Espa?ola de Enfermería Nefrológica , 2011,
Abstract: Introducción: En México se estima que entre el 70 y el 80% de los pacientes que ingresan a diálisis lo hacen de forma urgente, esto se traduce en mayor morbimortalidad, mayores costos y menor eficacia organizativa en los servicios de nefrología. Objetivo: Evaluar el impacto de una intervención dirigida a incrementar el conocimiento de la enfermedad renal sobre el inicio oportuno de la terapia sustitutiva. Hipótesis: El promedio del grupo en el conocimiento de la enfermedad renal después de la intervención es mayor al promedio previo a la misma. Material y Métodos: Dise o pre experimental (antes - después) muestra de 65 pacientes en estadio 5 de la IR (IC 95%) se sometió al grupo a cuatro sesiones educativas: Sobre la enfermedad renal crónica, la nutrición y la enfermedad renal crónica, cambios en el estilo de vida y diálisis peritoneal, lo que necesita saber. Se utilizo un cuestionario de 26 ítems (KR .8). Se utilizó estadística descriptiva y t de students (ns > 0.05). Resultados: Antes de la intervención el promedio de conocimiento fue de 60.76 incrementándose en 35.08 puntos posteriores a la misma. Previo a la intervención el nivel bueno se encuentra en 23.1% incrementándose a 98.5%. Se lograron cambios significativos en el nivel de conocimiento (t = 13.207 ns.000) El 93.80 aceptaron iniciar tratamiento posterior a la intervención. Conclusiones: Proporcionar educación sobre la enfermedad renal y sus opciones de tratamiento incrementa el conocimiento de la misma, favoreciendo la toma de decisiones acertadas para el inicio oportuno de la terapia sustitutiva. Introduction: In Mexico it is estimated that between 70 and 80% of patients who are admitted for dialysis are admitted as emergencies. This leads to higher mortality, higher costs and reduced organizational efficacy in the nephrology services. Aim: To assess the impact of an intervention aimed at increasing knowledge of kidney disease on the timely commencement of replacement therapy. Hypothesis: The group average knowledge of kidney disease after the intervention is higher than the average prior to the intervention. Material and Methods: Pre-experimental design (before-after): a sample of 65 patients with stage 5 CKD (95% CI) underwent four group educational sessions: About chronic kidney disease, Nutrition and chronic kidney disease, Changes in lifestyle and Peritoneal dialysis, what you need to know. A questionnaire containing 26 items (KR.8) was used. Descriptive statistics and the student's t-test were used (ns > 0.05). Results: Before the intervention, average knowledge was 60.76 which increas

Las bioconstrucciones de corales y sus facies asociadas durante el Malm en la Cordillera Ibérica Central (provincia de Zaragoza)
Aurell, M.,Meléndez, A.
Estudios Geologicos , 1987, DOI: 10.3989/egeol.87433-4599
Abstract: The differents types of bioconstructions and associated facies in the Central Iberian Chain (Higueruelas Formation, Upper Kimmeridgian) have been studied. Biohermes of different thickness (decimetric to metric) and less lateral continuity are developped, highly colonized by corals, that are associated to oncolitic, bioclastic and oolitic of high energy facies, in marginal areas, near the litoral developpment. At the same time takes place an important set up of mud mounds, with a small coral colonisation, in protected arcas in a inner shelf, or in outer areas, where the action of the waves is not so effective. The environment protection is been generated in some places due to the appearance of oolitic barrier islands. Se estudian los diferentes tipos de bioconstrucciones de corales, y sus facies asociadas, presentes en el sector central de la rama aragonesa de la Cordillera Ibérica, en la Formación Higueruelas (Kimmeridgiense superior). Se desarrollan biohermos de potencias métricas a decimétricas y escasa continuidad lateral, intensamente colonizados por corales coloniales, que se encuentran asociados a facies oncolíticas, bioclásticas y oolíticas de alta energía en zonas marginales, próximas al desarrollo litoral. Al mismo tiempo tiene lugar una importante instalación de mud mounds, con escasa colonización de corales, en zonas protegidas dentro de la plataforma interna o en zonas más externas, donde la acción del oleaje no es efectiva. La protección del medio viene condicionada en algunos puntos por la aparición de islas barrera oolíticas.
Evaluación de la interferencia de Rottboellia cochinchinensis sobre el maíz (Zea mays L.) a través de un método aditivo
Anzalone,A.; Meléndez,L.; Gamez,A.;
Revista de la Facultad de Agronomía , 2006,
Abstract: an essay was established in the "miguel angel luna lugo" experimental station of the agricultural sciences college at the universidad centroccidental ?lisandro alvarado? with the objective to evaluate the interference of rottboellia cochinchinensis on the height, the number of leaves, the total exposed dry biomass, estimated total yield after plantation, length of the ear of corn, weight of 100 corn grains, number of grains per row in the ear and yield of a corn plantation (zea mays l.), using an additive method. the design used was of random blocks with five treatments and four replications. the treatments consisted of 0, 2, 4, 8, and 12 r. cochinchinensis plants per square meter respectibly associated with the corn plantation. the different densities of r. cochinchinensis did not significantly the evaluated variables of vegetative development, but had an effect on the estimated yield, length of the ear of corn, number of grains per row in the ear, weight of 100 grains and yield of the corn crop. the losses caused by the weed were 84,76; 72,93; 50,99 and 55.21% for plant densities of 2, 4, 8, and 12 weed plants per square meter. the lowest yield was obtained for the case of 2 plants of r. cochinchinensis per square meter, what leads to believe the presence of a strong specific competition for this species of weed.

Revista de la Facultad de Agronomía , 2006,
Abstract: Con la finalidad de evaluar la interferencia de Rottboellia cochinchinensis sobre la altura, el número de hojas, la biomasa aérea seca total, rendimiento estimado a los 90 días después de la siembra, longitud de la mazorca, número de granos por hilera de granos en la mazorca, peso de 100 granos y rendimiento de un cultivo de maíz (Zea mays L.) a través de un método aditivo, se estableció un ensayo en la Estación Experimental "Miguel Angel Luna Lugo" del Decanato de Agronomía de la Universidad Centroccidental "Lisandro Alvarado". El dise o utilizado fue de bloques al azar con cinco tratamientos y cuatro repeticiones. Los tratamientos consistieron en 0, 2, 4, 8 y 12 plantas.m-2 de R. cochinchinensis asociadas al cultivo de maíz. Las diferentes densidades de R. cochinchinensis no afectaron significativamente las variables de desarrollo vegetativo evaluadas, pero si tuvieron efecto sobre el rendimiento estimado, la longitud de la mazorca, el número de granos por hilera de granos en la mazorca, el peso de 100 granos y el rendimiento en grano del cultivo de maíz. Las pérdidas del rendimiento en grano ocasionadas por la maleza fueron de 84,76; 72,93; 50,99 y 55,21% para las densidades 2, 4, 8 y 12 plantas.m-2 de la maleza, respectivamente. El menor rendimiento del maíz se obtuvo con la presencia de 2 plantas.m-2 de R. cochinchinensis, por lo que se presume que existió una fuerte competencia intraespecífica para la especie maleza.

Abstract: Se presenta la revisión taxonómica de las especies circunscritas al género Machaerium presentes en Venezuela, con el objetivo de interpretar el conocimiento en cuanto a los problemas nomenclaturales y de identificación que han existido a través de la historia de este taxon. Siguiendo el estudio clásico de observación de caracteres morfológicos en los exsiccata, se determinaron 39 especies y 11 variedades distribuidas en todo el territorio venezolano en un rango altitudinal de 0-1800 m snm. Se presenta una clave para la identificación de las especies basada en el patrón principal de morfología foliar y la descripción de cada especie. Se consolidan como nuevos registros para la flora de Venezuela a: M. capote, M. isadelphum, M. milleflorum y M. seemannii. Se reafirma el endemismo de: M. dubium, M. grandifolium, M. guaremalense, M. orthocarpum, M. striatum, M. tovarense y M. truxillense. Se propone una combinación nueva: Machaerium arboreum (Jacq.) Benth. var. cultratum (Pittier) Meléndez. Este estudio representa un aporte para la flora de la región neotropical, con información básica acerca de la fitodiversidad del país.

Consideraciones sobre la gobernabilidad como determinante del comportamiento electoral en Colombia: elecciones presidenciales de 2010
Fredy A. Barrero,Carlos Meléndez
Colombia Internacional , 2011,
Abstract: This article makes a contribution in the literature on electoral behavior in Colombia. Previous explanations have employed theories that emphasize the explanatory power of income, psico-social considerations and retrospective evaluation in order to assess the impact of programmatic, clientelistic and personalistic party-voter linkages on vote-choice. There is a gap in the literature that we propose to fill through the inclusion of governability appeals as a criterion that electors use when defining their electoral preferences. The fact that certain candidates are perceived with better conditions (or not) to overcome challenges to governability based on their links with powerful veto players is another factor that influences vote choice in addition to key variables (e.g. ideology). Original empirical information, based on the analysis of a national survey data, confirms the hypothesis proposed.

Bordisms of manifolds with proper action of a discrete group: signatures and descriptions of $G$-bundles
A. S. Mishchenko,Quitzeh Morales Meléndez
Mathematics , 2011,
Abstract: In this work the equivariant signature of a manifold with proper action of a discrete group is defined as an invariant of equivariant bordisms. It is shown that the computation of this signature can be reduced to its computation on fixed points sets equipped with their tubular neighborhoods. It is given a description of the equivariant vector bundles with action of a discrete group $G$ for the case when the action over the base is proper quasi-free, i.e. the stationary subgroup of any point is finite. The description is given in terms of some classifying space.
