Producción comparativa de chícharo de vaca (vigna unguiculata) y frijol (phaseolus vulgaris) en riego y en sequía
Arturo Díaz,Alfredo S. Ortegón
Agronomía Mesoamericana , 2000,
Abstract: Producción comparativa de chícharo de vaca (Vigna unguiculata) y frijol (Phaseolus vulgaris) en riego y en sequía. Se comparó la productividad de seis genotipos de chícharo de vaca (Vigna unguiculata) y dos variedades de frijol (Phaseolus vulgaris), en dos condiciones, una en riego y otra en sequía. En riego, California Blackeye No. 5 la mejor producción de vaina y 29144 , 56061/BRE y California Blackeye No. 5 el mayor rendimiento de grano. En frijol, Pinto Anzalduas 91 registró el mayor rendimiento de grano. En sequía se presentó clorosis férrica y hubo un amplio rango de severidad entre las especies y cultivares. No se registraron precipitaciones durante el ciclo y sólo tres genotipos de chícharo de vaca llegaron a producir vaina y grano; California Blackeye No. 5 fue la mejor productora de vaina y grano. Las variedades de frijol no produjeron grano. La mayoría de los genotipos de chícharo de vaca sobresalieron en la producción de materia seca. La mayor altura de planta fue en chícharo de vaca y se correlacionó (r= 0,71) con materia seca. Resultó contrastante la productividad de las dos especies entre las condiciones evaluadas, aunque destacó el mayor potencial productivo del chícharo de vaca sobre el frijol
Competitividad productiva de cuatro híbridos de Okra en fechas de siembra en el norte de Tamaulipas
Díaz Franco, Arturo;Ortegón Morales, Alfredo Sergio;Ramírez de León, José Alberto;
Agricultura técnica en México , 2007,
Abstract: the main okra producing area in mexico is northern tamaulipas. in this region yearly production occurs in two periods, an early sowing period from february to march, and a late sowing period from april to may. in this region cultivars of the clemson spineless 80 type are widely grown. the yield of okra hybrids px41596, px41696, cajun delight and cajun delisht, was evaluated in four planting dates in 1998 (feb 26, mar 18, apr 17, and may 11) and 1999 (march 1st and 20th, april 19, and may 11), at rio bravo, tamaulipas, mexico. in comparison with cv. clemson spineless 80, early fruit yield (first month of harvest production) and total fruit yield of the hybrids was significantly superior in 227 and 29%, respectively. the highest fruit and foliar chlorophyll content were observed in hybrids px41596 and px41696, both traits were correlated (r2= 0.77**). in both years, the highe st early fruit yield (3101 kg ha-1) was obtained in the early sowing period. the february 26, 1998 and march 1 st, 1999 sowing dates, gave the highest total fruit yield (14 975 kg ha-1) and the higher plant height (112.8 cm). the highest values of early fruit yield (3172 kg ha-1), total fruit yield (16 501 kg ha-1), plant height (99 cm), and harvest period (13 to 15 weeks) were registered in 1999. positive correlations were found between early and total fruit yield (r= 0.60* *), and between total fruit yield and plant height (r= 0.85**). the okra hybrids tested had a higher productivity than the cv. clemson spineless 80.
Seroprevalencia de brucelosis en trabajadores de mataderos de municipios del Tolima (Colombia)
Morales Ortegón,Diego Fernando; Combariza Bayona,David Andrés;
Revista Ciencias de la Salud , 2004,
Abstract: human brucelosis is usually detected on personnel whom keep permanent closer cattle contact or frequently ingestion of inadequate cattle derivated processed products. methods: a cross-sectional study was designed to determinate the seroprevalence of brucella infection in workers of slaughterhouses of the tolima region (colombia). a group of 186 workers were evaluated by using serological test like rose bengal test, complement fixation test and elisa. results: an aproximated 4% prevalence of brucella antibodies were detected in the examinated population. showy correlation between seropositive and hygienic work conditions were founded. conclusions: slaugtherhouses workers have an elevated risk infection due to unfavorable work hygienical conditions.

La temperatura en la etapa reproductiva del cultivo de canola (Brassica napus L.)
Ortegón Morales, Alfredo Sergio;Díaz Franco, Arturo;González Quintero, Javier;Garza Cano, Idalia;
Agricultura técnica en México , 2006,
Abstract: the elevated production of canola in the world, has promoted the formation of hybrids and cultivars with adaptation to a wide range of environments. this crop is being introduced in some regions of north and central mexico, including the state of tamaulipas. the objective of this study was to determine the environmental effect of temperature (heat units) on the reproductive period and yield of canola during the period of 2003-2004 at rio bravo, tamaulipas, mexico. four cultivars and two hybrids were tested. there sowing dates were established and data taken included begining of flowering, physiological maturity, duration of reproductive stage, accumulation of heat units, number of pods per plant, seed weight per plant, 1000-seed weight, dry matter and seed yield at harvest. with the exception of yield per plant, volumetric seed weight and dry matter, the response of the genotypes was signifi cant for the other seed yield components and with the interaction between seed yield and planting date. the infl uence of moderate temperatures during the reproductive stage in the first planting date was manifested by an average increase of 22.2 days in the reproductive period as compared to the second and third planting dates. the hyola 40 1 hybrid was the earliest, more stable, and higher yielder, and the duration of its reproductive stage was not affected across planting dates.
Enredos, chismes y camarillas
Ortegón Twiggy Malena
Maguaré , 2002,
Abstract: El propósito específico es el de introducir un análisis de la función estratégica del chisme, en la gestión de los conflictos y en la definición de lealtades y alianzas para actuar colectiva- mente. Se trata de experimentar en el buen sentido, con temas y situaciones que insertas muchas veces en lo mas fino de la interacción social, son potentes para impedir la construcción de estructuras de confianza, convivencia y deliberación, en un con- texto que exige mas y mejores herramientas, para desactivar los terribles dilemas sociales que enfrenta Colombia.

Abstract: Resumen Entre los distintos estudios que relacionan la literatura de creación con el psicoanálisis clínico y su comprensión metapsicológica, se destaca el papel ilustrador del arte y la literatura en la explicación del pensamiento psicoanalítico. Este trabajo discute el concepto fundamental de la transferencia, teniendo como referente la locura de Cardenio, un personaje de Don Quijote de La Mancha. Varios elementos técnicos del quehacer psicoanalítico florecen alrededor del estudio de esta idea.

Sánchez Valdivia,Alfredo; Sánchez Padrón,Alfredo;
Revista Cubana de Medicina , 2004,
Abstract: the encephalopathy is defined as a deterioration of the mental state or the level of conscience begun by processes out the brain. on the other hand the sepsis for some time, is defined as the infection evidence more the presence of a systemic inflammatory answer. the septic encephalopathy was described for the first time in 1827, but only recently has become a topic of global neurological interest. the septic encephalopathy is reported in until 70% of the septic patients. the fisiopathology of this entity is without doubts very complex and dark and motivates us to carry out this revision article, for to be the form more common of encephalopathy in the units of progressive cares.
