Reembolización de arterias uterinas por hemorragia posparto en una segunda gestación
Nuria López V,Gabriel Vegas G,Sara Arrieta B,Carlos Iglesias S
Revista Chilena de Obstetricia y Ginecología , 2012,
Abstract: La hemorragia posparto es la principal causa de muerte obstétrica. Presentamos el caso de una gestación y parto normales tras la embolización bilateral de ambas arterias uterinas, por hemorragia posparto en la gestación anterior. La paciente requirió de una nueva embolización bilateral de arterias uterinas en esta segunda gestación con buen resultado obstétrico. La embolización arterial pélvica en el manejo de la hemorragia posparto refractaria al tratamiento médico, permite en ocasiones evitar el tratamiento quirúrgico, conservando la fertilidad de la paciente. The postpartum hemorrhage is the main cause of obstetric death. We report a case of normal pregnancy and delivery after bilateral embolization of uterine arteries due to postpartum hemorrhage in a previous pregnancy. A new bilateral embolization of uterine arteries was needed in this second pregnancy with good obstetric results. The pelvic arterial embolization in the management of postpartum hemorrhage refractory to medical treatment, avoids the surgical treatment, preserving fertility.

Revista de la construcción , 2011, DOI: 10.4067/S0718-915X2011000100005
Abstract: with last planner, obtained from lean construction (construction without losses), where there will be realized an implementation of this system to a subcontract of a construction company, to strengthen deficient aspects that debilitate the performance of the fulfillment of the aims of the company. it realized a training and implementation of last planner system to a subcontract, obtaining excellent results with respect to meeting work commitments acquired by him, efficiency in finding, eliminating or diminishing the reasons by which the activities are not delivered in the approved period, learning in planning own work and the consequence of overcoming the variability and uncertainties of the construction industry. finally it was concluded that, although applicable to such subcontract showed favorable results, not impact on the overall performance of the construction company that work, however it is projected that the system be applied massively to subcontracts of a work of construction, significant improvement can be discerned, undermining the main reason why the construction did not meet their goals, the performance of subcontracts.

Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.329160
Abstract: Gravity data are sensitive to local vertical offsets across high-angle faults, where rocks with different densities are juxtaposed. Yet high densities in some Mesozoic sedimentary rocks just above the basement may smear out the subtle gravity signatures of basement faults. At this study the gravity data processing tends to avoid ill-described “black-box” techniques. The study area is situated in the Palomas site, Cuatrociénegas region, Coahuila, NE Mexico. The San Marcos Fault is at least 300 km long and has WNW-ESE trend from the central part of Nuevo León State through Coahuila, and finally to the eastern part of Chihuahua State. Gravimetric data shows that the lowest values of free air and Bouguer anomalies are in the southern part of the area, and the highest values are in the western and central part of the area. Between these parts exists a zone of high horizontal gravity gradient. Configuration of linear elements of gravity field (gradient zones) delimited the San Marcos Fault in the San Marcos valley below thickness of recent sedimentary cover. Two density models were carried out, which showed that the Cretaceous rocks are in discordant contact with the Paleo- zoic rocks that can be related to the San Marcos Fault. The density was determinate using to Nettleton’s method, which results highlight the presence of the San Marcos Fault. Density models showed that the Quaternary sediments are in direct contact with the San Marcos Fault.

Abstract: The principles of Good Governance presume peoples, nations, systems, corporations, cultures and so forth. These entities are what must be found at the backdrop of a possible Good Governance in Nigeria. Meanwhile the collapse of any civilization; the decay of any society; the death of the human spirit in any epoch is often heralded by the deterioration of culture. In other words anarchy in and disintegration of any society are consequent upon a decline, decadence, misconstrue or neglect in the culture of that society. Identifying the veritable Nigerian culture is a task outside whose accomplishment Good Governance in the country remains a farce, because it is a people who generate culture and a culture which grounds Good Governance. The quest for Good Governance in Nigeria is a pipe dream; a flight of fancy in as much as the Nigerian people is phantom and their culture inanity. Meanwhile it is more convenient to talk about the people, culture, language and religion of Nigeria in plural terms. Therefore we can only say Nigerian cultures, languages and religions. It was John S. Mbiti [1] and Emefie I. Metuh [2] who had agreed on this plurality only in terms of African Religions. Plurality as diversity is the essential character of Nigeria. We may conveniently talk about the Igbo (Likewise Yoruba, Hausa, Kalabari, Ogoni, Ibibio, Tiv and so on) culture, language, religion, people and so forth. Yet even at that, what we mean can easily identify with the past and dying ways of the people which the present recalls according to the strength of their hindsight, but which has no relevance at all on the life of those who commemorate them. This article from a phenomenological perspective understands culture as a unified way of life that binds a people together and identifies its absent presence in Nigeria with the inevitable consequence of the illusiveness of Good Governance. It then opens the vistas of another possibility of building Good Governance on the same diversity.

Abstract: omphalitis problems are very common in cattle farms, but its origin is occasionally unknown. with this study it was sought to isolate and identify bacterial pathogens, omphalitis producers in calves. a cross sectional nonprobabilistic study of no convenience was performed in calves affected by omphalitis, using 35 calves, aged between 3 to 90 days, randomly selected at ten live-stook farms in the municipality of cereté-córdoba (colombia). the animals were evaluated by conducting a general clinical exam and detailed examination of the umbilicus, thus determining the production of inflammation at this organ and taking into account the absence or presence of fistula with drainage of purulent material. 48.57% of the calves observed showed omphalitis cannulae, while 51.42% did not present this problemwith cannulae. 100% of the animals studied had omphalitis. the most prevalent bacteria obtained from the samples were staphylococcus aureus (22,5%), escherichia coli (22,5%), staphylococcus sp. (15%), klebsiella sp. (9,68%), proteus vulgaris (9,68%), pseudomona sp. (6,46%), proteus mirabilis (3,23%), enterobacter sp. (3,23%), chryseobacterium meningosepticus (3,23%), alcaligenes sp. (1,40%), citrobacter koseri (1.40%). it should be noted that 37% of the isolated bacteria were umbilical infections belonging to the group of total coliforms, which indicated the absence of a strict aseptic procedure in the management of neonatal umbilicus.

Abstract: Las onfalitis son problemas muy frecuentes en las explotaciones bovinas, razón por la cual, con el presente trabajo, se pretendió aislar e identificar agentes bacterianos productores de onfalitis en terneros. Se realizó un estudio descriptivo de corte transversal, de tipo no probabilístico de conveniencia en terneros con onfalitis; se utilizaron 35 terneros con edades comprendidas entre 3 y 90 días de nacidos, escogidos en diez explotaciones ganaderas, del municipio de Cereté, Córdoba. Los animales fueron evaluados mediante la realización de un examen clínico general y examen detallado del ombligo, determinando así la presentación de inflamación, a este nivel, y teniendo en cuenta la ausencia o presencia de fístula, con secreción de material purulento. El 48,57% de los animales estudiados presentaron onfalitis fistulada y el 51,42%, onfalitis no fistulada. El 100% de los animales estudiados manifestaron onfalitis. Las bacterias con mayor prevalencia en las muestras analizadas fueron Staphylococcus aureus (22,5%), Escherichia coli (22,5%), Staphylococcus sp. (15%), Klebsiella sp. (9,68%), Proteus vulgaris (9,68%), Pseudomona sp. (6,46%), Proteus mirabilis (3,23%), Enterobacter sp. (3,23%), Chryseobacterium meningosepticus (3,23%), Alcaligenes sp. (1,40%), Citrobacter koseri (1.40%). Cabe destacar que el 37% de los agentes etiológicos aislados en la infecciones de ombligo pertenecen al grupo de los coliformes totales, lo que indica que no existe un riguroso procedimiento de asepsia en el manejo de ombligo del neonato.

Modeling Landscape Evapotranspiration by Integrating Land Surface Phenology and a Water Balance Algorithm
Gabriel B. Senay
Algorithms , 2008, DOI: 10.3390/a1020052
Abstract: The main objective of this study is to present an improved modeling technique called Vegetation ET (VegET) that integrates commonly used water balance algorithms with remotely sensed Land Surface Phenology (LSP) parameter to conduct operational vegetation water balance modeling of rainfed systems at the LSP’s spatial scale using readily available global data sets. Evaluation of the VegET model was conducted using Flux Tower data and two-year simulation for the conterminous US. The VegET model is capable of estimating actual evapotranspiration (ETa) of rainfed crops and other vegetation types at the spatial resolution of the LSP on a daily basis, replacing the need to estimate crop- and region-specific crop coefficients.
Curital INIA: Nueva Variedad de Zapallo Italiano (Cucurbita pepo L.) del Tipo Negro Chileno
Bascur B.,Gabriel;
Agricultura Técnica , 2006, DOI: 10.4067/S0365-28072006000400012
Abstract: the zucchini squash (cucurbita pepo l.) type ?negro chileno? is the most cultivated in chile; its fruit is conic shaped, elongated and dark green in color with light green longitudinal stripes. plant and fruit characteristics are variable and it has a low yield potential. the scarce commercial cultivars available for this type of squash, the production and quality problems that affect the small farmer, and the high cost of seed of some hybrid cultivars, have been the motivation for this breeding project in the la platina research center of the agricultural research institute. starting from plants selected from commercial plantings of the ?negro chileno? zucchini and using self-pollination and inter-pollination methods were obtained pure lines, which were evaluated in different seasons and locations. this allowed the identification of several lines with very good growth, fruit quality and high yield potential, from which the variety curital inia was obtained. this new variety, of open pollination, is characterized by an erect growth habit, high fruit production at the first harvest, and an 18.9% yield increase with respect to the ?negro chileno? type. its fruit is of a cylindrical shape, brilliant, dark green color with light green stripes.
TREPADOR-INIA: VARIEDAD DE POROTO VERDE (Phaseolus vulgaris L.) PARA CULTIVO BAJO INVERNADERO

Agricultura Técnica , 2002, DOI: 10.4067/S0365-28072002000100016
Abstract: as a result of the genetic improvement work carried out with green pod beans by la platina regional research center, the national agricultural research institute (inia) has developed the variety trepador-inia. this new cultivar was obtained by masal selection from a local ecotype, collected in the province of san felipe, v region, chile, and is recommended as a greenhouse crop, mainly for rotation between two tomato cycles with the benefits this implies from a phytosanitary point of view. its most important characteristics are its climbing habit and its large flat light green threadless pod. it is an early cultivar starting production around 65-70 days after planting with a harvest period of 30-40 days, and high yield potential which varies between 15-30 t ha-1 depending if planted in autumn or spring. its green pod yield, evaluated in different locations and crop seasons, was significantly better than the enriqueta cultivar, which has traditionally been grown in greenhouses. it is recommended for temperate zones where the greenhouse furnishes the temperature required by the bean plant, but respecting this condition it can be planted in any period. another possibility is to use it outside in the spring-summer season with stakes or a trellis and get similar yields to those produced in greenhouses.
