Estudio del deterioro de materiales aislantes secos mediante técnicas de alta tensión (descargas parciales)
García Quintero,Edwin;
Ingeniería y Desarrollo , 2010,
Abstract: in this work the damage on low density polymeric isolated material is evaluated (ethylene-propylene) in a power wire of 12/20 kv, from the partial discharges technique (pds) for three different types of objects: one without defect and other two with it (drilling with pointed object and connection). additionally to this, a function of patterns is to set out and allow to quantify, visualize and to discriminate defects in the same isolation. this just with the purpose to obtain on the three test tubes, which of them show the most relevant defect and in consequence let us to know the total damage on the isolated system. as results, we find that connections are the most important damages followed by the defect due to the drilling on the isolation. in relation with the patterns function pds, this one, make a good difference among defects highlighting in a graphic and qualitative way, the most relevant, and so, improvement some deficiencies showed by the functions of patterns that already exist.
Tratamiento penitenciario en la provincia de Buenos Aires: El desafío de ajustar la legislación a la práctica internacional
Quintero,Fabián A.;
Revista Opinión Jurídica , 2011,
Abstract: the penitentiary treatment in the province of buenos aires (argentina), is regulated by the law 12.256 in generic form. this norm does not make any difference among the general conditions to guarantee the feasibility of the penitentiary treatment and the objectives and reaches of the treatment itself. differentiating the three aspects of the penitentiary function that is, the penitentiary treatment, the penitentiary attendance, and the preservation of rights of people in jail, the purpose here is to analyze the current instruments which establishes the legislation and consequently to pose possible adjustments to international norms. the necessity for modifications which allow defining the intervention object, to delineate the objectives and their reaches, to determine the base conditions of the intervention and to guarantee long term evaluations, correcting in this way the structural myopia of the penitentiary institutional program, is deduced from a compared analysis.

Rapprochement with the Jesuit debates in the village of Santiago de Cali. A study based on the press, 1849-1850
Carolina Abadía Quintero
HISTOReLo : Revista de Historia Regional y Local , 2010,
Abstract: The objective of the article at hand is to show the opinion and controversy created by the arrival of the Society of Jesus to Santiago de Cali, expressed in articles which were published in the newspapers El Sentimiento Democrático and El Ariete. The text explains how the religious presence of the Jesuits served to revive the conflict among the liberal and conservative parties in 1849 and 1850. The author contextualizes the problem form the distinct political tendencies and the role of “order,” which were manifested during the liberal government of José Hilario López. In particular, the fear the liberal factions had with regard to the impact of the Society in politics, New Granada education, and society in general; likewise, the role and the position of the conservatives in defense of members of a religious order and with regard to the liberal reforms of the times. Finally, the author exposits what the role was of the parents with regard to the presence of the Jesuits and their compliant with reference to the direction of the Colegio de Santa Librada in Santiago de Cali and the reaction of some democratic societies and liberal factions in the locality.

Estudio del deterioro de materiales aislantes secos mediante técnicas de alta tensión (descargas parciales)

Ingeniería y Desarrollo , 2010,
Abstract: En este trabajo se evalúa el deterioro del material aislante polimérico de baja densidad (Etileno-Propileno) en un cable de potencia de 12/20 kV, a partir de la técnica de descargas parciales (DPs), para tres tipos de objetos de ensayo: una sin defecto y dos con defectos (perforación con objeto puntiagudo y empalme). Adicionalmente, se plantea una función de patrones de DPs que permita cuantificar, visualizar y discriminar un defecto frente a otro en el mismo aislamiento; todo esto con el fin de determinar, entre las tres probetas (o cable) de ensayo, cuál de ellas presenta el defecto más relevante y, en consecuencia, que pueda conducir más rápidamente al da o total del sistema aislante. Como resultado se obtuvo que el empalme es el deterioro más importante, seguido por el defecto debido a la perforación del aislamiento. En cuanto a la función de patrones de DPs planteada, esta discrimina muy bien los defectos, resaltando gráfica y cuantitativamente los más relevantes, y de esta manera mejora algunas deficiencias presentadas por las funciones de patrones ya existentes.
Perfil serológico y antibiotipia de cepas de Streptococcus pneumoniae aisladas de portadores nasales pediátricos.
Quintero,Beatriz; Araque,María;
Investigación Clínica , 2006,
Abstract: the aim of this study was to determine the serotype profile and antibiotyping of streptococcus pneumoniae from nasal isolates in children. nasopharyngeal swab samples obtained from 125 children were cultivated and screened for the presence of s. pneumoniae. strains were identified according to standard microbiological methods. the isolates were serotyped by the quellung reaction and resistance patterns were determined by the microdilution method according to nccls guidelines. results indicate an overall pneumococcal carriage rate of 24% (n=30). the most commonly isolated serotypes were 23f (20%), 6b (20%) and 14 (13%). 73% of isolates were resistant at least to one of the tested antibiotics. 47% of the strains were consistently resistant to penicillin and the serotypes 6b and 23f were frequently associated with this marker. 60% of the strains were resistant to doxycycline, 37% to trimethoprim/sulfamethoxazole and clindamycin, 30% to erythromycin, 23% to cloramphenicol, 7% to ceftriaxone and 3% to cefepime. all strains were sensible to ofloxacin, rifampin and vancomycin. the most common combined resistance patterns were pnc-eri-tmp/smx-dox-clo-cli (16.59%) and pnc-dox (13.27%). the results obtained in this study will allow to orient the empiric therapy for pneumococcal infections and a rational use of antibiotics in clinical practice, as well as the application of an appropriate vaccination program specially adapted to the serotypes more frequently found in children.
Sentido pedagógico de la evaluación. Estudio de caso en la Facultad de Ciencias de la Pontificia Universidad Javeriana
Vargas Quintero,María Victoria;
Universitas Scientiarum , 2008,
Abstract: educational assessment is an activity which is supported on a pedagogical foundation related to all human dimensions, in particular the cognitive, emotional and social spheres. because of the above reasons, assessment is a complex task. as it is de-contextualized from its fundamentals and simplified, assessment loses its pedagogical sense; this is what happens when it is reduced to routines apparently detached from its objectives. at the cognitive level assessment has a formative as well as a diagnostic dimension. when the diagnostic dimension prevails in the assessment, marking is over dimensioned and formative aspects are therefore ignored. three different conflicts were found in the studied group. the first one refers to undertaking assessments that have no sense for students. the second one refers to the lack of pedagogical sense in the assessment process. and the third one refers to an assessment process which is not integral but instead focuses in the cognitive dimension only.

Relación entre la variación de las condiciones ambientales y la temperatura interna de la yema del manzano 'Anna' Inner bud temperature of' Anna' apple trees in relation to varying environmental conditions
Casierra Posada Fannor,Quintero A.
Agronomía Colombiana , 2001,
Abstract: En Paipa (Colombia), se realizó un ensayo de campo con el fin de determinar el efecto de la variación de las condiciones ambientales sobre la temperatura interna de la yema del manzano 'Anna' cultivado en condiciones de altiplano tropical. Los registros se hicieron en un árbol de cuatro a os, el cual se defolió manualmente y se podó pocas semanas después de la cosecha. Se midió la temperatura del aire y se comparó con la temperatura de una yema en el árbol. Para medir la temperatura de la yema se colocó un sensor digital muy delgado entre los catáfilos de la yema; la temperatura ambiente se registró con un termómetro de bulbo. Las mediciones se realizaron cada media hora entre las 7:00 y las 17:30 horas del día, durante 19 días, empezando el día en que el árbol fue defoliado hasta cuando la yema alcanzó el estado fenológico "green tip". Al tiempo con cada medición de temperatura se registró el fenómeno climático más sobresaliente (lluvia, tiempo soleado, viento, tiempo nublado, etc.) y los datos se agruparon según cada fenómeno climático. Los resultados mostraron que la yema presentó una temperatura 1,49°C por encima de la temperatura del aire durante el transcurso del día, en la noche no hubo diferencia de temperatura. En condiciones de lluvia, la temperatura de la yema estuvo 0,57°C por encima de la temperatura del aire. Bajo cielo nublado la yema estuvo 0,56°C más cálida que el aire. En condiciones de viento la yema presentó una diferencia de 0,87°C sobre la temperatura del aire. En días soleados, la yema mantuvo una temperatura 2,3°C sobre la temperatura del aire. Las diferencias entre la temperatura del aire y la de la yema se discuten con base en la transpiración, la convección y la radiación. A field experiment was conducted in Paipa (Colombia) to study the effect of environmental varying over inner bud temperature of an 'Anna' apple tree 4 years old growing in tropical highlands. The tree was defoliated and prunned any weeks after harvest. Air temperature and bud temperature were compared. Bud temperature was measured with a fine digital sensor between the bud scales, to measure the air temperature a normal bulb termometer was used. Temperatures were measured during 19 days from 7:00 to 17:30 hours, starting at defoliation day to "green t ip" bud development stage. The outstanding environmental phenomenon (rain, sunny day, wind, cloudy sky, etc.) was registered simultaneous with the air and bud temperature measures and the information was grouped accourding to the environmental phenomenon. Results shaw that bud temperature was 1,49°C over air te
