Al-Zī al-Mustawfà de Ibn al-Raqqām y los apogeos planetarios en la tradición andaluso-magrebí
Díaz-Fajardo, Montse
Al-Qantara : Revista de Estudios Arabes , 2005,
Abstract: The manuscript 2461 extant in the Rabat General Library contains a third zī of the astronomer Mu ammad ibn al-Raqqām al-Andalusī (d. 1315): al-Zī al-Mustawfà. The canons (chapter 18) and the table of the motion of the apogee that appear in al-Mustawfàare related to Is āq al-Tūnisī (fl. 1193-1222) who, probably, compiled a set of tables without canons. Ibn al- Raqqām knew well Ibn Is āq′s Zīj of which we knew, until recently, two recensions: : al- Zī al-'āmil y al- Zī al-Qawīm. In al-Mustawfà, a third recension of the same work, Ibn al- Raqqām clarifies what was Ibn Is āq′s opinion about the motion of the planetary apogees and gives information related to the different opinions the astronomers of the Andalusian-Maghribī school had on this topic. El manuscrito 2461 de la Biblioteca General de Rabat conserva un tercer zī del astrónomo Mu ammad ibn al-Raqqām al-Andalusī (m. 1315): al-Zī al-Mustawfà. Los cánones (capítulo 18) y la tabla del movimiento del apogeo de al-Mustawfà están relacionados con el trabajo de Ibn Is āq al-Tūnisī (fl. 1193-1222), quien compiló, probablemente, un conjunto de tablas carentes de cánones. Ibn al-Raqqām conocía bien el zī de Ibn Is āq del que realizó dos recensiones conocidas hasta ahora: al- Zī al-'āmil y al- Zī al-Qawīm. En al-Mustawfà, tercera recensión de la misma obra, Ibn al-Raqqām aclara cuál era la opinión de Ibn Is āq sobre el movimiento de los apogeos planetarios y la división que existía, a este respecto, entre los astrónomos de la escuela andaluso-magrebí.
El capítulo sobre el Tasyīr en al-Bāri de Ibn Abī-l-Ri āl y su traducción alfonsí
Díaz-Fajardo, Montse
Al-Qantara : Revista de Estudios Arabes , 2011,
Abstract: Tasyīr or “prorogation”, is an astrological procedure with which the astrologer moves, in an imaginary way, an indicator in order to determine the celestial influences. Tasyīr was one of the astrologer’s fundamental tools for the casting of a horoscope. This paper analyzes the information in the chapter on Tasyīr in Ibn Abī l-Rijāl’s (11th century) book al-Bāri‘, concerning the methods, the techniques and the resources used. Its study highlights the channels through which science was transmitted and the ways in which the astrologer wrote his work using other sources, and stresses the importance of al-Bāri‘ in introducing new astrological knowledge from the East into the Maghrib and medieval Europe (knowledge that was used until the fifteenth century). The comparison of the chapter with its Castilian translation provides evidence of the procedures used by the translators of Alfonso X. El tasyīr o prorrogación es un procedimiento astrológico por el que se hace avanzar de forma imaginaria un indicador para conocer las influencias celestes. El tasyīr fue una de las herramientas fundamentales del astrólogo en el levantamiento de un horóscopo. Este artículo analiza la información que contiene el capítulo “Sobre el tasyīr” de la obra al-Bāri‘ de Ibn Abī-l-Ri āl (siglo XI): los métodos, las técnicas y los recursos que utilizaba. Su estudio nos muestra las vías por las que la ciencia se transmitía, el modo en el que el astrólogo elaboraba su obra, la importancia del al-Bāri‘ como introductor en el Magreb y en la Europa medieval de fuentes y conocimientos nuevos importados de Oriente y la vigencia de su astrología hasta el siglo XV. El cotejo del capítulo mencionado con su traducción castellana nos da pruebas de la forma de trabajar de los traductores de Alfonso X.

Abstract: El Proceso de Atención de Enfermería es un método científico en el quehacer de la profesión, en el cuidado del individuo sano o enfermo, familia y comunidad. Se valoró el nivel de conocimiento que tienen los estudiantes de cursos para trabajadores en la especialidad de Neonatología y Atención Integral a la Mujer para la aplicación del Proceso de Atención de Enfermería, en el Instituto Politécnico de la Salud "Simón Bolívar", durante el curso escolar 2000/01, cuya muestra estuvo constituida por 19 alumnos coincidiendo con el universo, matriculados en el curso en el curso para trabajadores. Se realizó una investigación descriptiva prospectiva. Se diagnosticaron los conocimientos y deficiencias que presentaron los estudiantes en cada contenido mediante la realización de un proceso con un caso real antes de recibir la asignatura. Durante su impartición se realizaron comprobaciones prácticas en cada contenido y al finalizar la misma se realizó un proceso con un caso real. Se obtuvo información acerca de los conocimientos y deficiencias que tienen los estudiantes antes y después de impartida la asignatura. La impartición de la asignatura posibilitó la erradicación de las mayorías de las deficiencias que tenían los estudiantes en la aplicación práctica en este proceso, pero aun persisten dificultades que se erradicaran con la realización sistemática de las auditorias concurrentes y retrospectivas.

Abstract: Twelve years old patient (YGS), female, white, of rural origin; with history of facial and truncal bullae since the age of eight months when exposed to the sun light. It was first diagnosed as solar dermatitis. At the age of 6 it was assessed as xeroderma pigmentosum. This diagnosis was confirmed at the age of 10 by the histopathology department and reassessed by the National Reference Centre. For the infrequency of this disease, a bibliographic revision was carried out to make a report for this case presentation. Paciente YGS, de 12 a os de edad, blanca, femenina, de procedencia rural, con antecedentes de padecer de ampollas en cara y tronco desde los 8 meses de edad al exponerse al sol. Se diagnosticó inicialmente por Médico de Familia y pediatra del área como una dermatitis solar. A los 6 a os se valoró por Dermatología y se planteó xeroderma pigmentoso, diagnóstico que fue confirmado por histopatología a los 10 a os de edad y revaluado por el Centro de Referencia Nacional. Por lo infrecuente de esta enfermedad de la piel, se realizó revisión bibliográfica al respecto con el propósito de confeccionar un informe para la presentación del caso.

Revista Colombiana de Biotecnología , 2003,
Abstract: En Colombia, actualmente existen genotipos de papa con excelente calidad industrial pero muy susceptibles a P. infestans. La mejor manera de combatir este problema es mediante resistencia genética, puesto que la inversión para controlar esta enfermedad por medios químicos es muy costosa, sin olvidar la contaminación ambiental que producen. El objetivo de este trabajo fue la identificación de genes R1 y R2 en los diferenciales de papa respectivos (Solanum tuberosum ssp. tuberosum) mediante evaluación de resistencia a P. infestans y la detección molecular por medio de PCR (alelo R1) y AFLP (alelo R2). Para la detección del alelo R1 fueron empleados los primers GP179, GP21, 76-2SF2/76-2SR, SPUD237 y Sol 2749-2770F / Sol 3246-3267R. Los primers GP179, GP21 y SPUD237 fueron inespecíficos para Rl, ya que se generó un producto de amplificación en los diferenciales 1 y 2, así como también en Solanum phureja. Los primers 76-2SF2/76-2SR, y Sol 2749-2770F / Sol 3246-3267R generaron un producto de amplificación en los diferenciales 1 y 2; por el contrario, el fragmento estuvo ausente en el material susceptible. Para la detección del alelo R2, fueron implementados cinco marca-dores AFLP, de los cuales sólo dos fueron reconocidos visualmente en el diferencial 2. Los resultados mostra-ron una evidente correspondencia fenotípica y genotípica con respecto a la presencia de los genes Rl y R2. La identificación molecular de genes de resistencia a P. infestans permitirá desarrollar programas de mejoramiento genético que beneficien directamente los rendimientos de los cultivos de papa, sobre todo los de mayor interés industrial para nuestro país. Excellent industrial quality potato genotypes are currently available in Colombia; however, they are very sus-ceptible to P. infestans. The best way of fighting this problem is by genetic resistance, given that the expense of controlling this disease through chemicals is high, plus the environmental contamination provoked. This work try to identify R1 and R2 major genes in respective potato differentials (Solanum tuberosum ssp. tuberosum) by evaluating P. infestans resistance and their molecular detection by PCR (allele R1) and AFLP (allele R2). GP179, GP21, 76-2SF2/76-2SR, SPUD237 and Sol 2749-2770F/Sol 3246-3267R markers were used for R1 allele detection. GP179, GP21 and SPUD237 markers were non-specific for Rl because an amplification product was generated in differentials 1 and 2 as well as S. phureja. 76-2SF2/76-2SR and Sol 2749-2770F/Sol 3246-3267R markers created an amplification product in differentials 1 and 2, whilst the

Abstract: Introducción: el 50 % de la patología oncológica en pediatría corresponde a masas o tumores sólidos, alrededor del 20 % del total se ubica en abdomen. Los tumores que se presentan con mayor frecuencia en el abdomen son el nefroblastoma o tumor de Wilms, el linfoma tipo Burkitt, el neuroblastoma y los tumores germinales de ovario. Objetivo: presentar un caso pediátrico con tumor abdominal. Caso clínico: se presenta un caso de una ni a de 8 a os de edad con antecedentes de salud aparente, atendida en el Hospital Público de la Universidad de Mbarara, Uganda. Resultado: paciente pediátrica que fue ingresada con una historia de 3 meses de dolor abdominal, pérdida ligera de peso y masa abdominal de crecimiento rápido, fue sometida a una laparotomía exploradora donde se resecó la masa tumoral, la que histológicamente arrojó ser un linfoma ovárico, como hallazgo durante la intervención quirúrgica se diagnosticó una agenesia de útero. Conclusión: la paciente se encuentra después del tratamiento con quimioterapia en seguimiento, lleva aparentemente hace 5 meses una vida normal (noviembre 2011). Introduction: 50 % of pediatric oncologic pathology corresponds to mass or solid tumors, reaching about 20 % of total abdomen. The tumors that most frequently occur in the abdomen are nephroblastoma or Wilms tumor, Burkitt's lymphoma, neuroblastoma, and ovarian germ cell tumors. Objective: to present a pediatric case with abdominal tumor. Case report: we report a case of an 8 year old girl with a history of apparent good health. This patient was assisted the Public Hospital of Mbarara University, Uganda. Result: a female pediatric patient was admitted with a 3-month history of abdominal pain, mild weight loss, and rapid growth of an abdominal mass. This patient underwent an exploratory laparotomy where the tumor mass was removed. It was histologically confirmed as an ovarian lymphoma. It was diagnosed uterus agenesis. Conclusion: after chemotherapy, the patient is controlled, and she has an apparently normal life for already 5 months (November 2011).
