Revista mexicana de ciencias agrícolas , 2011,
Abstract: La orografía y agroecología del estado de Guerrero es muy diversa y en las áreas agrícolas de altitud intermedia (1 200 a 1 700 m), prácticamente no se siembran variedades mejoradas, debido a condiciones climáticas y edáficas poco favorables, por lo que dificulta establecer un programa de mejoramiento genético de maíz para cada nicho ecológico. En estas regiones se examinó la estabilidad de 25 variedades de maíz, durante cinco ciclos agrícolas verano-oto o de 2005 a 2009; con el propósito de identificar una cruza intervarietal estable, consistente y con buen potencial de rendimiento a través de ambientes. La información se analizó en 20 variedades, usando un dise o de bloques completos al azar con tres repeticiones por localidad y combinando localidades. Con esta información se estimó los parámetros de estabilidad propuestos por Eberhart y Russell y descritos por Molina; además se aplicó el modelo de efectos principales aditivos e interacción multiplicativa (AMMI). Los progenitores masculinos V15 y V16 mostraron estabilidad y consistencia a través de ambientes; similar comportamiento mostraron las cruzas intervarietales V3, V7 y V9, además fueron sobresalientes en rendimiento de grano; V11 fue consistente y mostró mayor potencial productivo en ambientes desfavorables. Las cruzas intervarietales V1, V4, V6, V10, la variedad local del agricultor V13 y los progenitores femeninos V17, V18 y V20, mostraron buena respuesta en ambientes favorables pero fueron inconsistentes. Los dos métodos usados registraron resultados semejantes, por lo que fue posible seleccionar tres variedades por su potencial de rendimiento de grano, estabilidad y consistencia en los ambientes. The topography and agro-ecology of the Guerrero State is diverse and in agricultural areas of intermediate elevation (1 200 to 1 700 m), almost no improved varieties are planted, due to unfavorable climatic and soil conditions, so it is difficult to establish a maize breeding program for every ecological niche. In these regions, the stability of 25 maize varieties was examined, during five summer-autumn crop seasons from 2005 to 2009; aiming to identify an intervarietal cross that was stable, consistent and with good yield potential through the environments. The data was analyzed in 20 varieties, using a randomized complete block design with three replications by location and combining locations. Using this information, the stability parameters proposed by Eberhart and Russell, and described by Molina were estimated, also the additive main effects and multiplicative interaction model (AMMI) was ap

Abstract: En las regiones semicálidas del estado de Guerrero (alrededor de 1 500 m de altitud), prevalece la siembra de semillas nativas (criollos), pero también se tienen áreas en las que se pueden establecer maíces mejorados. En el presente trabajo se proponen dos cruzas intervarietales como alternativa, para que los agricultores incrementen la producción de grano; estas se seleccionaron después de evaluar el comportamiento agronómico de cinco variedades progenitoras y sus cruzas posibles en arreglo factorial; dos de ellas, de origen tropical, seleccionadas al menos por 10 generaciones para adaptarse a los Valles Altos y las otras tres de germoplasma nativo subtropical, obtenidas en el estado de Guerrero; además, de las seis cruzas intervarietales y sus progenitores, se agregaron la variedad local del agricultor y seis variedades testigo para evaluarlos en un dise o de bloques completos al azar con cuatro repeticiones, en el ciclo primavera-verano de 2009, en dos localidades de altitud intermedia. El análisis combinado a través de ambientes mostró diferencias significativas en rendimiento de grano, entre cruzas, progenitores y testigos. Las cruzas intervarietales VS-529*VE-1 y VS-529*VE-3 fueron superiores en rendimiento de grano a sus progenitores, la variedad local del agricultor y los testigos comerciales tuvieron otros atributos, como mejor sanidad de mazorca y planta, expresión intermedia para altura de planta, días a floración masculina y femenina, y menor acame. Las variedades progenitoras subtropicales per se fueron ligeramente superiores en rendimiento de grano, peso de mazorca y diámetro de mazorca comparadas con las variedades tropicales, pero éstas presentaron ligeramente mejor sanidad de planta y mazorca. Los progenitores VE-1, VE-3 y VS-529 presentaron efectos de ACG positiva, sus cruzamientos fueron los que mostraron mayor rendimiento de grano, heterosis, precocidad, mejor aspecto de planta y mazorca, mientras que CIST y SINT-3 -HE exhibieron efectos de ACG negativos. Estos resultados permitieron seleccionar las cruzas intervarietales con características agronómicas favorables y con potencial productivo aceptable, como opción para apoyar a la agricultura tradicional de maíz de áreas intermedias del estado de Guerrero. In the semi-warm regions of Guerrero (about 1 500 m elevation) prevails sowing with native seeds (Landrace), but there are also areas where improved maize can be established. In this paper we propose two intervarietal crosses as an alternative for farmers to increasing grain production, and these were selected after evaluating the ag

Abstract: in the semi-warm regions of guerrero (about 1 500 m elevation) prevails sowing with native seeds (landrace), but there are also areas where improved maize can be established. in this paper we propose two intervarietal crosses as an alternative for farmers to increasing grain production, and these were selected after evaluating the agronomic performance of five parent varieties and their possible crosses in a factorial arrangement; two of them of tropical origin selected at least 10 generations to adapt to the highlands and the other three from native subtropical germplasm, obtained in the state of guerrero; also, besides the six intervarietal crosses and their parents, the local variety of the farmer and six varieties as a control were added to evaluate in a randomized complete block design with four replicates in the spring-summer, 2009, in two localities of intermediate elevation. the combined analysis across the environments showed significant differences in grain yield among crosses, parents and the controls. the vs-529*ve-1 and vs-529*ve-3 intervarietal crosses were higher in grain yield to their parents, the local variety of the farmer and commercial controls had other attributes, such as better ear health and plant expression intermediate for plant height, days to male and female flowering, and less lodging. the subtropical parent varieties per se were slightly higher in grain yield, ear weight and ear diameter compared with the tropical varieties, but they had slightly better health of plant and ear. parents ve-1, ve-3 and vs-529 had positive general combining ability (gca) effects; their crosses were those that showed higher grain yield, heterosis, earliness, better-looking plant and ear, while cist and sint-3-he exhibited negative gca effects. these results allowed to selecting the intervarietal crosses with favorable agronomic characteristics and production potential acceptable as an option to support the traditional corn of intermediate areas of the stat

Abstract: Se presentó un paciente que nace severamente deprimido por parto natural, a las 35,4 semanas, con peso de 2 620 g. Inmediatamente se comenzaron medidas de reanimación, con bolsa, pero al no mejorar se decide intubación traqueal. Se planteó malformación de vías respiratorias por imposibilidad de lograrlo; al intentar traqueotomía, la tráquea está ausente, planteándose el diagnóstico de agenesia traqueal. A pesar de las medidas terapéuticas tomadas, el paciente fallece 8 horas después del nacimiento. En el estudio patológico se comprobó la presencia de agenesia traqueal tipo II, de acuerdo a la clasificación de Floyd. We present the case of a patient, who was born severely depressed by natural birth, at 35,4 week, weighting 2 620 g. Immediately he was given reanimation, with bag, but when there was not an improvement, we decided the tracheal intubation. We supposed the malformation of the respiratory ways when the intubation was impossible; when we tried to make a tracheotomy, we did not find the trachea, arriving to the diagnosis of tracheal agenesis. In spite of the taken therapeutic measures, the patient died 8 hours after birth. In the pathologic study we stated type II tracheal agenesis, according to Floyd's classification.

Abstract: Large quantities of spent hydrodesulfurization (HDS) catalysts are available from petrochemical industry. Disposal of spent catalyst is a problem as it falls under the category of hazardous industrial waste due to its vanadium concentration. Most of these catalysts are usually supported on alumina containing a variable percentage of elements such as nickel or molybdenum. Hence these catalysts contain environmentally critical, and economically valuable metals such as molyb denum, vanadium, and, nickel. In this paper, a spent HDS catalyst was treated with caustic soda solution. Parameters such as temperature, time, and NaOH solution concentration have been studied thoroughly, in order to settle the appropriate conditions for the maximum recovery of molybdenum and vanadium. Under the best leaching conditions (20 %w NaOH, room temperature, 2 h) about 95% recovery of Mo and V was achieved, and the recovery of nickel obtained was of 99% in the form of NiAlO4.

Abstract: the municipality of gibara has historically been known by its diversity in agricultural crops and particularly for its tradition in the cultivation of common bean (phaseolus vulgaris l.), an important leguminous staple in the diet of the local population. in this municipality, the town of velasco is known as cuba's granary. in this region producers have common bean losses during storage that in many occasions affect the economic revenues, its availability for consumption and the seed for planting, however, farmers do not know the causes that provoke those losses. it was for the above reasons that this study was conducted during the years 2003-2005 with the aim of estimating the damage and losses of the common bean in the traditional storage system in the municipality of gibara. to achieve the objective a methodological procedure proposed by (raboud et al., 1984), that fits to the domestic conditions was used. the results verified that the producers do not always use the appropriate practices for the handling of dry beans before being stored and not all have appropriate storage facilities to keep large volumes of grain without loosing its quality and quantity. the losses in storage can be up to 10% according to the storage conditions. the greatest damage and losses were caused by pathogenic fungus and insects, which were favoured by the combination of a high initial moisture content and temperature in the mass of the stored grain.

Abstract: Durante el ciclo O-I 02-03 se formó un dialélico con16 poblaciones de origen tropical y subtropical. Las cruzas ysus progenitores fueron evaluados durante el ciclo P-V2003en el Campo Experimental Bajío- INIFAP. Con el objetivo deidentificar las mejores poblaciones que permitan reforzar losprogramas de hibridación tanto en su estructura heterótica como en las fuentes de derivación de líneas. La información fueanalizada mediante el método de Gardner y Eberhart con elcual, al separar los componentes de varianza, se estiman losefectos genéticos aditivos y no aditivos. Entre los resultadosmás relevantes se observó que no obstante la respuesta hete-rótica involucrada en la formación de estas poblaciones, elpatrón heterótico tropical x subtropical se expresó en combinaciones específicas como PABGTx Sint B IG y SintPABG I ACG x Sint A IG. con rendimientos de 12,5 y 12,4t/ha respectivamente. En estos mismos cruzamientos se obtuvieron los máximos valores de heterosis específica que podríaaprovecharse a través de Selección Recurrente Recíproca. Lapoblación Sint. A IG de origen tropical, presentó el mayorefecto varietal, y por su adaptación al subtrópico constituyeun material prometedor para integrarlo al Programa de Mejoramiento Genético del Bajío. El mayor valor de heterosis varietal se observó en el sintético PABG I GH A lo cual es unindicador de Aptitud Combinatoria General que puede ser utilizado como probador. Un análisis más detallado, permitirá aprovechar este germoplasma en beneficio de los programasde mejoramiento genético de maíz.
