Abstract: Se presenta el caso de un angiofibroma juvenil nasofaríngeo, en un paciente del consultorio médico No. 9, que pertenece al Policlínico Integral Docente "Carlos Manuel Portuondo" de Marianao. Se reconoce la importancia de realizar una historia clínica detallada, así como un minucioso examen físico, por el médico de familia y el otorrinolaringólogo del área de salud, que incluyó la rinoscopia posterior, para poder llegar al diagnóstico de esa patología, y realizar la extirpación precoz del angiofibroma, mediante el proceder quirúrgico. Se concluyó que el diagnóstico clínico se correspondió con el histopatológico, y que la conducta quirúrgica temprana es resolutiva en la afección.

Gualberto Buela-Casal
International Journal of Clinical and Health Psychology , 2005,
Abstract: En este trabajo se analiza la productividad científica de las universidades espa olas. Los objetivos son: a) conocer la situación de las universidades espa olas en el Ranking Académico de las Universidades del Mundo; b) estudiar la relación entre criterios internacionales de productividad científica utilizados en ese ranking y algunos criterios nacionales, tales como los tramos de investigación, los programas de doctorado con mención de calidad y la productividad en tesis doctorales; c) analizar la relación entre la proporción de Profesores Titulares de Universidad (PTU) y Catedráticos de Universidad (CU) y el porcentaje de tramos de investigación. Para ello se realiza un estudio descriptivo mediante análisis de documentos, y como unidades de análisis su utilizaron los datos aportados por el Ranking Académico de las Universidades del Mundo, los datos de la Agencia Nacional de Evaluación de la Calidad y Acreditación sobre los doctorados con mención de calidad y los ofrecidos por el Consejo de Coordinación Universitaria. Los resultados ponen de manifiesto que Espa a es el duodécimo país con más universidades en el Ranking Mundial, que los criterios internacionales de productividad científica se relacionan con los criterios nacionales estudiados, y que hay una clara relación entre la proporción de PTU/CU y la productividad científica, en el sentido que aquellas universidades que tienen una alta proporción de CU tienen una menor productividad en tramos de investigación, y viceversa.
Complete Synchronization of Strictly Different Chaotic Systems
Gualberto Solís-Perales
Journal of Applied Mathematics , 2012, DOI: 10.1155/2012/964179
Abstract: The criteria for complete synchronization of strictly different chaotic systems using feedback control are presented in this paper. Complete synchronization is achieved when all the states in the slave system are synchronous with the corresponding state in the master system. We illustrate that using a single input and single output control scheme, the synchronization of a class of strictly different systems is obtained in partial form. To overcome this problem we show that a multiple input and multiple output control scheme with an equal number of inputs and outputs than the order system is required in order to obtain the complete synchronization. This procedure is used to synchronize the Rössler and the Chen systems as an example. We also demonstrate that if the synchronization scheme considers less inputs and outputs, the partial-state synchronization is obtained.

Estudio del efecto del Compensador Estático de Reactivos en el problema de Flujo de Carga
Ruiz Porras,Walter; Boza Valerino,Juan Gualberto;
Ingenier?-a Energ??tica , 2012,
Abstract: this work consists on studying, to model and to simulate a static vars compensator (svc), to analyze the effect of the same one in the load flow problem of an electric power system (sep). a program is used, of the revised literature, written in matlab. the mathematical model of the svc is presented that is used in the program and that it uses the concept of susceptance variable shunt and it incorporates the model of the fire angle of the tiristores like state variable in newton raphson methods. the results obtained are compared in the load flow, without svc, in the rehearsals that are carried out with the system of 9 bars of the ieee with the reached results using the academic version of the power world simulator. the svc is used to control the value of the voltage in one of the bars of the case study.
Diversidade genética de Chenopodium ambrosioides da regi?o cacaueira da Bahia com base em marcadores RAPD
Santos, Simone Gualberto;Corrêa, Ronan Xavier;
Pesquisa Agropecuária Brasileira , 2006, DOI: 10.1590/S0100-204X2006000100022
Abstract: chenopodium ambrosioides l. is known in many parts of brazil for its medicinal properties, mainly used to control intestinal worms. its genetic diversity is little studied. the objective of this work was to evaluate the genetic variability of 16 accessions of c. ambrosioides from the cocoa region of bahia state, brazil, by the rapd technique (random amplified polymorphic dna). only 6.9% of the 216 amplified rapd bands were polymorphic and the pattern of dispersion of individuals showed no clustering related to sample site. therefore, there is low variability among accessions and it is distributed among the accessions from the entire sampled region.
La percepción del tiempo: influencias en la salud física y mental
Universitas Psychologica , 2011,
Abstract: with a broad understanding of time perception, the dimensions positive past, negative past, fatalistic present, hedonistic present and future were grouped in profiles to assess relations with physical and mental health. using a quasiexperimental design, 50 subjects matched for age and sex completed the zimbardo time perspective inventory and the sf-36, with 3 measures of time estimation. pearson correlations and anova showed significant relationships between dimensions, physical and mental health, and estimation. three profiles were obtained, with the balanced one (btp) having the best health indicators. these results support the idea that it is good to have a balanced profile that implies a positive attitude to the past, future orientation, and enjoying pleasant experiences. also, health is influenced by time estimation.
Internacionalidad de las revistas de psicología multidisciplinar editadas en iberoamérica e incluidas en la Web of Science
Universitas Psychologica , 2010,
Abstract: international journals are considered more prestigious and with more quality than national ones, although the meaning of this had not been established until recently. moreover, internationality has been used as a criterion to make important decisions, for example to assess the performance of scientists, universities, doctoral degree programs, and so on, without knowing the exact meaning of internationality. thus, the current study uses the criteria of internationality established by a survey on more than 16,000 scientists from all over the world to create an internationality index of multidisciplinary psychology journals published in ibero-america and included in the web of science. results show that the most international journal is revista latinoamericana de psicología, followed by the spanish journal of psychology, psicothema and universitas psychologica. all the journals fulfill the criteria for internationality and the study provides very important results which will allow its increase.
