Los estromatolitos del cerro Pan de Azúcar, Sierras Pampeanas Occidentales, San Juan, Argentina. Correlaciones y significado estratigráfico
Peralta,Silvio H.; Castro de Machuca,Brígida;
Serie correlaci?3n geol?3gica , 2010,
Abstract: the occurrence of stromatolites ("bowl-shaped", conocollenia? and planar cryptalgal laminites), in limestone beds exposed at the pan de azucar hill (31° 25' s - 67° 27' w), western sierras pampeanas, san juan province, argentina, is reported. the stromatolite-bearing rocks are interlayered within retrograde greenschist facies metamorphic rocks related to the crystalline basement (valle fértil complex) of the nearby sierra de la huerta. the stromatolitic structures are described and interpreted as domal-laminated, bowl-shaped and planar stromatolites. stratigraphic correlations with the upper cambrian stromatolite levels of the la flecha and zonda formations and the upper cambrian-early tremadocian la silla formation of eastern and central precordillera, and with the crystalline limestones of the cambrian angaco formation, and the neoproterozoic difunta correa metasedimentary sequence at the pie de palo range, are discussed herein. also, the correlation with the neoproterozoic stromatolite levels from the tandilia system are considered. on the basis of the geochronologic and biostratigraphic correlation, a probable late proterozoic (ediacaran)-lower cambrian age is suggested for the cerro pan de azucar stromatolitic limestones.

Abstract: the globalization process and the digital revolution have brought new challenges for the companies' competitiveness. one of these new requirements is the change of the managerial scope of the entire supply chain. the management of a supply chain requires, among other aspects, integrating key-business processes along the chain. in this sense, this work has the main purpose of identifying the relationship between processes integration along the supply chain and its customer service performance. in order to achieve this aim, an exploratory research was conducted, focusing on a footwear supply chain located in the city of franca, state of s?o paulo, brazil, which constitutes itself a good example of a consolidate supply chain already inserted in the international footwear market. the results obtained enable to conclude that the performance of the customer service in the studied footwear supply chain is directly related to the integration of order fulfillment processes, demand management, and product development processes involving not only the integration of shoe manufacturers with customers, but also with key suppliers. it still can be pointed out that this performance is also related to the existence of internal competences in the processes considered in the studied companies.

Abstract: we present a 100-year reconstruction of siliceous export production from sediments of the puyuhuapi channel (44° s, 70° w) in the chilean fjords. we use accumulation rates and concentrations of diatoms and silicoflagellates, organic carbon (corg) and biogenic opal (siopal) as proxies of export production, and fluctuations in the contribution of freshwater diatoms as proxies of rainfall in the hinterland and river runoff. box core sediments collected at two sites within the puyuhuapi channel were analyzed: station 35 (at the head of the fjord; 56 m water depth) and station 40 (in the middle of the channel; 270 m water depth). surface sedimentation rates were 0.75 cm yr-1 at station 35 and 0.25 cm yr-1 at station 40. siopal content averaged ~ 4 % at both sites. diatom accumulation rates as well as the contribution of freshwater diatoms were higher at the head of the fjord (1.59 1010 valves m-2 yr-1 and 22 %, respectively) than in its middle (1.08 1010 valves m_2 yr_1 and 14 %, respectively). diatom abundances were two orders of magnitude higher than silicoflagellate contribution at both sites. in general, diatoms typical of high nutrient environments characterize the puyuhuapi channel sediments: at both sites, spores of the genus chaetoceros dominated the diatom assemblage (> 40 % of total diatoms; spores of chaetoceros radicans/cinctus, ch. constrictus/vanheurcki, ch. debilis and ch. diadema). downcore analysis reveals an overall increase in the production of siliceous microorganisms from the late 19th century to the early 1980s, and then a decrease until the late-1990s. we associate a decrease in freshwater diatom contribution since the mid-1970s which we associate with a concomitant decline in rainfall in the chilean fjords. we suggest that this decline is related to the global atmospheric and oceanic warming of the past ~ 25 years

Abstract: La incidencia del embarazo ectópico se ha multiplicado mundialmente en las últimas décadas, incluyendo a Cuba, causando morbimortalidad en mujeres jóvenes constituyendo un problema de investigación. Se propone una estrategia de intervención educativa para contribuir a la gestión del conocimiento sobre el embarazo ectópico, en la Atención Primaria de Salud. Se realizó estudio prospectivo descriptivo durante los a os 2004 al 2007, de las pacientes ingresadas con sospecha de Embarazo Ectópico, en el Hospital Docente Ginecobstétrico de Matanzas “Dr. Julio Alfonso Medina”, para determinar el comportamiento de la entidad a través de variables operacionalizadas como: edad, diagnóstico y formas clínicas y tratamiento; en las pacientes que cumplían con los criterios de inclusión los datos se procesaron utilizando el paquete estadístico SPSS para Windows Versión 11.5, tabulando los resultados. La incidencia del EE se elevó hasta 34,2 por mil nacidos vivos, siendo más alta en el grupo de 25-34 a os (54.8%), el 80.3% se diagnosticó tardíamente y predominó la forma clínica complicada (59%), lo que motivó el 87.2% de salpingectomías realizadas. Existe dificultad con el diagnóstico precoz y remisión oportuna de las pacientes con sospecha de la entidad en la Atención Primaria de Salud. Proponemos dise ar un sitio Web sobre el tema del Embarazo Ectópico, basado en las Tecnologías de la Información y la Comunicación, para mejorar la capacitación de los internos y Medicina General Integral, en la Atención Primaria de Salud, donde existe el Policlínico Universitario.

Abstract: La Diabetes mellitus constituye un problema de salud a nivel mundial y la Diabetes en menores de 15 a os ha tenido un incremento en los últimos tiempos. En Cuba y en la provincia de Matanzas se ha observado similar situación. La atención integral al paciente diabético en edad pediátrica se lleva a cabo por el servicio de Endocrinología del Hospital Pediátrico Eliseo Noel Caama o y hasta el momento, a pesar de la revisión bibliográfica realizada, se ha constatado que ni en el país ni fuera de éste, se ha efectuado una evaluación de dichos pacientes desde el punto de vista dermatológico, lo que constituye lo novedoso de esta investigación. Por esta razón se realizó un estudio prospectivo- descriptivo de todos los enfermos, en edades comprendidas entre 0 y 15 a os, con diagnóstico de Diabetes mellitus con el objetivo de definir la presencia de enfermedades dermatológicas y determinar la evolución de éstas teniendo en cuenta el control metabólico. Se encontró que las afecciones predominantes fueron las infecciones micóticas, bacterianas y el Acné Juvenil y no se estableció relación entre el control metabólico y la evolución de las enfermedades dermatológicas halladas en el estudio. Se recomendó realizar esta investigación en casos y controles así como incorporar el tema del cuidado de la piel en la educación de estos pacientes.

Abstract: In order to evaluate the effect of ammonization in the production residue of Brachiaria brizantha seeds in the performance and in vivo biometric measurements of sheep, 19 Santa Inês lambs (females and non-castrated males) were used, with initial weight of 15kg, confined in individual cages until reaching 28kg. Animals were arranged into two groups, receiving isoenergetic and isoproteic diets with 40:60 volumous:concentrate ratio, being diet 1 (D1) made up with non-treated volumous with urea + addiction of urea in concentrate and diet 2 (D2) with treated volumous with addiction of 2% urea in MS + concentrate without urea. Dry matter consumption was similar between diets and sexes (0.85 kg/day, 3.28%/BW e 73.15 g/kg0,75/day); however, the remaining performance parameters were affected by the different sexes of animals. There was not interaction between diet and sex in biometric measurements; however, body length was higher for females (66.50 cm) compared to males (61.12 cm). We conclude that the effect of ammonization in diet volumous did not affect performance and biometric measurements of sheep terminated in confinement, being that some changes occurred due to the different sexes of the animals. KEY WORDS: Chemical treatment, nutritional value, sheep, urea, volumous. Para avaliar o efeito da amoniza o no resíduo da produ o de sementes de Brachiaria brizantha no desempenho e nas medidas biométricas in vivo de ovinos, foram utilizados dezenove cordeiros (machos n o castrados e fêmeas) da ra a Santa Inês, com peso inicial de quinze kg, confinados em gaiolas individuais até atingirem 28 kg. Distribuíram-se os animais em dois grupos, recebendo dietas isoenergéticas e isoproteicas com rela o volumoso:concentrado 40:60, sendo a dieta 1 (D1) constituída de volumoso n o amonizado + inclus o de ureia no concentrado e D2 com volumoso tratado com inclus o de 2% de ureia na MS + concentrado sem ureia. O consumo de matéria seca mostrou-se similar entre as dietas e sexos (0,85 kg/dia, 3,28%/PV e 73,15g/kg0,75/dia), porém os demais parametros de desempenho foram afetados pelos diferentes sexos dos animais. N o houve intera o entre dieta e sexo nas medidas biométricas. No entanto, o comprimento corporal foi superior para fêmeas (66,50 cm) em compara o aos machos (61,12 cm). Conclui-se que o efeito da amoniza o no volumoso da dieta n o afeta o desempenho, nem as medidas biométricas de ovinos terminados em confinamento. Algumas altera es que ocorrem relacionaram-se ao diferente sexo dos animais. PALAVRAS-CHAVES: Ovinos, tratamento químico, ureia, valor nutritivo, v
