    Gaucher, C.; Sprechmann, P.

    1998-01-01

    The fossil content of the Vendian to Lower Cambrian Arroyo del Soldado Group of the Nico Perez Terrane of Uruguay is analysed.Organic walled microfossils represented by acritarchs, eukariotic algae (sensu lato) and iron bacteria are recognized. An updated list of these microfossils is presented, which were are now reported in the Yerbal and Barriga Negra formations.Events of weutrphic conditions were reconstructed. The occurrence of Cloudina riemkeae, the earliest known metazoanwith a mineralized skeleton is communicated for the first time in Uruguay. The organic walled microfossils as well as Cloudina riemkeae are indicative of a Vendian age, whereas the trace fossils of the uppermost unit(Cerro Victoria) suggest the Early Cambrian. This would imply that the Group contains the Precambrian-Cambrian boundary. The Arroyo del Soldado Group is correlated with the Jacadiga and Corunba Groups (Brasil) and the Nama Group (Namibia).

    Uruguay, officially "The Oriental Republic of Uruguay," is a country of 176,215 sq km with a temperate climate and a good water supply, which contributed to the emergence of stock raising as the economy's traditional base. 1.31 million of the country's 2,940,200 people live in Montevideo, the capital and only large city. The population is 85%-95% white and 66% Roman Catholic. The dominant culture and official language is Spanish, although 25% of the people are of Italian origin. The annual population growth is only 0.5%, due to a low birth rate and large net outmigration. Infant mortality in 1986 was 27.1/1000, and life expectancy was 73 years. Literacy is 96%, due to an extensive system of public and private education. There is a large, urban middle class, which enjoys a high standard of living. 22% of the work force is in industry, 21% in government, 15% in commerce, and 28% in services. The 1986 gross domestic product was $6.2 billion, per capita $1701. The annual growth rate is now 6.3%, which is an upturn from the generally stagnant economic conditions of the last 30 years. 1986 exports were $834 million (mainly meat, wool, hides, and leather goods); imports were $870 million. Inflation averages 76.4%, and 270 pesos=$1.00. The major economic problem is managing the huge external debt of almost $5.4 billion. In 1987 Uruguay reached a debt rescheduling agreement with creditor banks and the International Monitary Fund, stretching out repayment dates through 2004. Exchange rates were allowed to float in 1982, and the country is trying to reduce the burden of the excessively large government sector through various privatization schemes. Uruguay has also been working with Argentina and Brazil toward integrating their economies. The only aboriginal inhabitants of Uruguay were the Charrua Indians. In 1811 Jose Gervasio Artigas led Uruguay's revolt against Spain, and total independence was achieved in 1828. Jose Batlle y Ordonez, who served as president from 1903 to

    Full Text Available This paper extends the study of party organization and legislative voting to factionalize party systems. After developing a typology of factional types, it argues that hierarchically organized factions respond to a competing incentive system. Factions have interests that push them to work together for the good of the party, but at the same time, they have interests in distinguishing themselves for electoral purposes. Further, the electoral cycle drives the weights of these competing pressures, leading factional cooperation to break down as elections near. These patterns and incentives are particularly evident in Uruguay, and the paper uses roll-call data from that country's legislature to test the propositionsEl presente artículo aplica el estudio de la organización de partidos y el voto legislativo a sistemas de partidos con facciones. Tras desarrollar una clasificación de los diferentes tipos de facciones, se argumenta que las facciones jerárquicamente organizadas responden a un sistema competitivo de incentivos. Pese a que las facciones tienen intereses que las empujan a trabajar juntas por el bien del partido, al mismo tiempo, tienen interés en diferenciarse unas de otras por propósitos electorales. Además, el ciclo electoral dirige los pesos de estas presiones competitivas provocando la ruptura en la cooperación entre las facciones conforme se aproximan las elecciones. Estas pautas e incentivos son particularmente evidentes en el caso de Uruguay, por lo que el artículo utiliza datos del voto nominal del Legislativo del país para probar estos argumentos.

    Full Text Available RESUMEN: Este trabajo versa sobre los grupos del magisterio racionalista en Argentina, y sobre todo Uruguay, a principios de la segunda década de este siglo, y su actitud frente a la enseñanza básica público-estatal, de carácter más o menos laico. Se sabe que el movimiento docente racionalista, según el modelo de Bakunin, Robin y Francisco Ferrer, y sobre una base libertaria y laicista radical, suponía un modelo alternativo de educación popular hacia 1910, de carácter público no estatal. En este estudio vamos a ver qué planteamientos ofrece este movimiento en algunos de los países más avanzados social y culturalmente de América Latina por aquellas fechas. También intentaremos evaluar algunas de las razones del relativo o total fracaso de proyectos significativos de educación laico-racionalista e integral del tipo del de la Liga Popular para la educación razonada de la infancia (L.P.E.R.I. en Uruguay. Muchos son los interrogantes que un propósito como el que anima este estudio plantea. Nos permitimos hacer un inventario de ellos en la conclusión. Pero ni que decir tiene que sólo investigaciones posteriores y mucho acopio de material documental in situ permitirán darles cumplida respuesta. Aquí y ahora, sólo se trata de poner un granito de arena al esclarecimiento del racionalismo educativo en América Latina.

    The succession exposed in the Burgueno Quarry, in the vicinity of Nueva Carrara (Maldonado, Uruguay), is here assigned to the Mina Verdun Group. It is composed, from base to top, by meta marls, calcareous breccias and limestones, stromatolitic limestones and massive dolostones. Exposed thickness exceeds 110 m. Stromatolites assigned to the group Conophyton occur in the stromatolitic limestones (El Calabozo Formation). Stromatolites are characterized by straight to sinuous columns, showing circular to elliptical transverse sections 1.5 to 26 cm in maximum diameter. Height of columns exceeds 50 cm. The stromatolitic laminations are well preserved. Sedimentary environment for this unit is inferred as sub tidal, under low energy conditions. The Las Ventanas Formation overlies with angular and erosional unconformity the Mina Verdun Group at Burgueno Quarry. The Las Palmas Formation is tentatively correlated with the Las Ventanas Formation, on the basis of stratigraphic relationships and lithologic similarity. Considering the data presented here, it is envisaged that the Lavalleja/Fuente del Puma Group is not part of the basement of the Las Ventanas Formation. A Proterozoic, pre-Vendian age is postulated for the Mina Verdun Group, thus older than ca. 600 Ma [es

    Pedogenic and non-pedogenic calcrete facies are very common feature of Marilia (Brazil) and Mercedes (Uruguay) formations in the Parana Basin. The non-pedogenic ones constitute massive limestone facies that have been recently interpreted as groundwater calcretes. These limestones are exploited in both countries to supply raw materials to Portland cement and soil conditioner in origin and age of calcretization phenomena. In Uruguay, the calcretization process seens to be band formation. Field relationships and fossil assemblage point to a Paleocene (or later) age for the calcretization. In Brazilian territory, the groundwater calcretes aresupposed to be of Upper Cretaceous age due to the presence of dinosaurs scattered through the Bauru Group, including siliciclastic beds below and above the calcretes. The authors assume that calcretization processes are similar in both countries (host rocks, intensity, size, textures, geometries and economic potential). The main difference is in age of the calcretization. (author)

    Most tratadistes consider that Sierra Ballena shear zone (SBSZ) is the western limit of an all octon block after the paper of Boss i and Gauche r (2004) showing a detailed geological map. The same method was applied to sporulation block in the Ne of Treinta y Tres city. It was obtained a 1/100.000 geological map with photo geology and 140 field data in an area of 3500 k m2. This document allowed to discover two kinds of mega - faults put in action at the same time (about 525 Ma): a mega shear zone N30E80E with proto - to ultramylonites similar to SBSZ and a regional thrust fault with vergence to NNW. The thrust fault has different features according to the affected type of rocks. At La Micaela, the mica schists are thrust ed by gneisses and migmatites. To the N W the gneisses became firstly sharply laminated and then, horizontal ultramylonites. Both kind of faulting produced at the same time may not be explained by an orthogonal collision and instead of it, is a naturalist proof of tangential collision and alcoholisation nature of the crustal block. In order to easily understand the new proposal it is necessary to change Paso del Dragón fm by Micaela fm, Cuchilla Dionisio Terrane by Treinta y Tres; Punta del Este Terrane by Punta del Este sub - terrane

The same method to the northern block NE of the city of Thirty- Three was applied. The geological map at 1:100,000 and 1:40,000 photogeology supported by field observations 140 covers an area of ​​3500 km2, allowed 525 Ma to discover that simultaneously produce sinistral megashear N30E, 80E and a mount (horse Amarillo ) with convergence towards the NNW . The megashear consists proto and ultramylonites petrológicamente being identical to ZCSB and age < 532 Ma The horse varies by rock type . On Micaela mica schist are ridden by gneisses and migmatites . In the center, the gneisses are rolled every few inches in W are ultramylonites sub - horizontal . The simultaneity of both phenomena is unexplained by head-on collision of cratons and explained by tangential collision from the SSE with tectonic transport to the north , representing a naturalistic aloctonía test

    The Cambrian radiation is one of the most exciting and controversial events in the fossil record. It was marked by a sudden abundance of shells, the first steep rise in plots of diversity through time, and the appearance of the fabulous soft-bodied fossils of the Burgess Shale in British Columbia and elsewhere in the world. The Cambrian radiation was also the subject of Steve Gould's Wonderful Life and Simon Conway Morris's Crucible of Creation.. The Ecology of the Cambrian Radiation is a long-awaited compilation that tackles one of the more impenetrable parts of the story. Interpretations of ecology are, after all, characteristically equivocal in rocks of this age.

    1985-02-01

    Cambrian trilobites occur in two levels (about 7 m apart) in the core of a large, complex anticlinal structure in the area between the Taylor Mountains and the Hoholitna River in southwestern Alaska. The lower collection contains Erbia, Macannaia (a species close to Soviet forms described as Pagetia ferox Lermontova), two species of Kootenia (including one perhaps cospecific with forms from the central Brooks range), and several species of ptychoparioid trilobites. It is clear that biogeographic affinities are with the transitional facies of the eastern Siberian platform and the south Siberian foldbelt. In Soviet terms, the age of the collection falls in a disputed interval called latest Early Cambrian (Tojonian) by some authors, and earliest Middle Cambrian (Amgan) by others. In North American terms, Macannaia is known only from early Middle Cambrian beds. The younger collection contains abundant agnostids, a variety of conocoryphids, Paradoxides, and several species of ptychoparioid trilobites. This is an assemblage of undoubted late Middle Cambrian age, comparable to faunas described from the Maya State of the Siberian platform and the Paradoxides paradoxissimus Stage of the Baltic region. Both faunas are from ocean-facing or outer shelf environments. None of the key non-agnostid or non-pagetiid elements have been seen previously in deposits of Cambrian North America.

    2014-08-01

    Full Text Available Upper lower Cambrian (provisional Cambrian Series 2 trilobites are described from three sections through the Shuangyingshan Formation in the Beishan area, northwestern Gansu Province, China. The trilobite fauna is dominated by eodiscoid and corynexochid trilobites, together representing at least ten genera: Serrodiscus, Tannudiscus, Calodiscus, Pagetides, Kootenia, Edelsteinaspis, Ptarmiganoides?, Politinella, Dinesus and Subeia. Eleven species are described, of which seven are identified with previously described taxa and four described under open nomenclature. The composition of the fauna suggests biogeographic affinity with Siberian rather than Gondwanan trilobite faunas, and the Cambrian Series 2 faunas described herein and from elsewhere in northwestern China seem to be indicative of the marginal areas of the Siberian palaeocontinent. This suggests that the Middle Tianshan–Beishan Terrane may have been located fairly close to Siberia during middle–late Cambrian Epoch 2.

    2004-08-22

    We report the discovery of sipunculan worms from the Lower Cambrian Maotianshan Shale, near Kunming (southwest China). Their sipunculan identity is evidenced by the general morphology of the animals (sausage-shaped body with a slender retractable introvert and a wider trunk) and by other features, both external (e.g. perioral crown of tentacles, and hooks, papillae and wrinkle rings on the body surface) and internal (U-shaped gut, and the anus opening near the introvert-trunk junction). The three fossil forms (Archaeogolfingia caudata gen. et sp. nov., Cambrosipunculus tentaculatus gen. et sp. nov. and Cambrosipunculus sp.) have striking similarities to modern sipunculans, especially the Golfingiidae to which their evolutionary relationships are discussed. This study suggests that most typical features of extant sipunculans have undergone only limited changes since the Early Cambrian, thus indicating a possible evolutionary stasis over the past 520 Myr.

    We review the salient evidence consistent with or predicted by the Hoyle-Wickramasinghe (H-W) thesis of Cometary (Cosmic) Biology. Much of this physical and biological evidence is multifactorial. One particular focus are the recent studies which date the emergence of the complex retroviruses of vertebrate lines at or just before the Cambrian Explosion of ∼500 Ma. Such viruses are known to be plausibly associated with major evolutionary genomic processes. We believe this coincidence is not fortuitous but is consistent with a key prediction of H-W theory whereby major extinction-diversification evolutionary boundaries coincide with virus-bearing cometary-bolide bombardment events. A second focus is the remarkable evolution of intelligent complexity (Cephalopods) culminating in the emergence of the Octopus. A third focus concerns the micro-organism fossil evidence contained within meteorites as well as the detection in the upper atmosphere of apparent incoming life-bearing particles from space. In our view the totality of the multifactorial data and critical analyses assembled by Fred Hoyle, Chandra Wickramasinghe and their many colleagues since the 1960s leads to a very plausible conclusion - life may have been seeded here on Earth by life-bearing comets as soon as conditions on Earth allowed it to flourish (about or just before 4.1 Billion years ago); and living organisms such as space-resistant and space-hardy bacteria, viruses, more complex eukaryotic cells, fertilised ova and seeds have been continuously delivered ever since to Earth so being one important driver of further terrestrial evolution which has resulted in considerable genetic diversity and which has led to the emergence of mankind.

  6. Proterozoic and early Cambrian protists: evidence for accelerating evolutionary tempo

    Science.gov (United States)

    Knoll, A. H.

    1994-01-01

    In rocks of late Paleoproterozoic and Mesoproterozoic age (ca. 1700-1000 million years ago), probable eukaryotic microfossils are widespread and well preserved, but assemblage and global diversities are low and turnover is slow. Near the Mesoproterozoic-Neoproterozoic boundary (1000 million years ago), red, green, and chromophytic algae diversified; molecular phylogenies suggest that this was part of a broader radiation of "higher" eukaryotic phyla. Observed diversity levels for protistan microfossils increased significantly at this time, as did turnover rates. Coincident with the Cambrian radiation of marine invertebrates, protistan microfossils again doubled in diversity and rates of turnover increased by an order of magnitude. Evidently, the Cambrian diversification of animals strongly influenced evolutionary rates, within clades already present in marine communities, implying an important role for ecology in fueling a Cambrian explosion that extends across kingdoms.

    Full Text Available A rich body of empirically grounded theory has developed about food webs--the networks of feeding relationships among species within habitats. However, detailed food-web data and analyses are lacking for ancient ecosystems, largely because of the low resolution of taxa coupled with uncertain and incomplete information about feeding interactions. These impediments appear insurmountable for most fossil assemblages; however, a few assemblages with excellent soft-body preservation across trophic levels are candidates for food-web data compilation and topological analysis. Here we present plausible, detailed food webs for the Chengjiang and Burgess Shale assemblages from the Cambrian Period. Analyses of degree distributions and other structural network properties, including sensitivity analyses of the effects of uncertainty associated with Cambrian diet designations, suggest that these early Paleozoic communities share remarkably similar topology with modern food webs.

Our results are relatively insensitive to the exclusion of low-certainty or random links. The many similarities between Cambrian and recent food webs point toward surprisingly strong and enduring constraints on the organization of complex feeding interactions among metazoan species.

  18. Tropical shoreline ice in the late Cambrian: Implications for earth's climate between the Cambrian Explosion and the Great Ordovician Biodiversification Event

    Runkel, Anthony C.; MacKey, T.J.; Cowan, Clinton A.; Fox, David L.

    2010-01-01

    Middle to late Cambrian time (ca. 513 to 488 Ma) is characterized by an unstable plateau in biodiversity, when depauperate shelf faunas suffered repeated extinctions. This poorly understood interval separates the Cambrian Explosion from the Great Ordovician Biodiversification Event and is generally regarded as a time of sustained greenhouse conditions. We present evidence that suggests a drastically different climate during this enigmatic interval: Features indicative of meteoric ice are well preserved in late Cambrian equatorial beach deposits that correspond to one of the shelf extinction events. Thus, the middle to late Cambrian Earth was at least episodically cold and might best be considered a muted analogue to the environmental extremes that characterized the Proterozoic, even though cooling in the two periods may have occurred in response to different triggers. Such later Cambrian conditions may have significantly impacted evolution preceding the Ordovician radiation.

  19. Diverging patterns of fertility decline in Uruguay

    Directory of Open Access Journals (Sweden)

    Mathías Nathan

    2016-03-01

    Full Text Available Background: The total fertility rate (TFR in Uruguay fell from 2.5 to 1.9 children per woman between 1996 and 2011. However, no study to date has examined the decline of the TFR by observing changes in fertility patterns by birth order. Objective: The main aim of this study is to analyze recent changes in fertility level and timing of childbearing by birth order in Uruguay. Methods: We estimate unconditional and conditional age- and birth-order-specific fertility rates for 1996-2011 using data from vital statistics, population census, and national population estimates. Additionally, three period summary measures of birth-order-specific fertility quantum are calculated: TFR, PATFR and TFRp*. Timing changes by birth order are examined with MAB and TMAB, focusing on MAB1 and its standard deviation and comparing their evolutions in Uruguay with those of selected countries. Results: Fertility decline fits a parity-specific stopping model with a moderate increase in the mean ages of first, second, and third births. The distribution of conditional fertility rates for first and second births depicts an asymmetric bimodal shape linked to the increasing heterogeneity of the timing of childbearing. Compared to countries with similar fertility trends, heterogeneity in the age at first birth in Uruguay is remarkably high. Conclusions: Previous studies suggest that heterogeneity in first and second birth timing is related to structural social inequalities, as women from lower social strata have not significantly changed the age at which they bear a first child, whereas women of middle to high social strata have started to postpone it. The new evidence reinforces the idea that postponement transition in Uruguay cannot be studied without considering this consolidation of social status polarization in fertility timing.

  20. Oxygen, ecology, and the Cambrian radiation of animals

    The Proterozoic-Cambrian transition records the appearance of essentially all animal body plans (phyla), yet to date no single hypothesis adequately explains both the timing of the event and the evident increase in diversity and disparity. Ecological triggers focused on escalatory predator-prey "arms races" can explain the evolutionary pattern but not its timing, whereas environmental triggers, particularly ocean/atmosphere oxygenation, do the reverse. Using modern oxygen minimum zones as an analog for Proterozoic oceans, we explore the effect of low oxygen levels on the feeding ecology of polychaetes, the dominant macrofaunal animals in deep-sea sediments. Here we show that low oxygen is clearly linked to low proportions of carnivores in a community and low diversity of carnivorous taxa, whereas higher oxygen levels support more complex food webs. The recognition of a physiological control on carnivory therefore links environmental triggers and ecological drivers, providing an integrated explanation for both the pattern and timing of Cambrian animal radiation.

  1. Early Cambrian pentamerous cubozoan embryos from South China.

    Directory of Open Access Journals (Sweden)

    Jian Han

    Full Text Available BACKGROUND: Extant cubozoans are voracious predators characterized by their square shape, four evenly spaced outstretched tentacles and well-developed eyes. A few cubozoan fossils are known from the Middle Cambrian Marjum Formation of Utah and the well-known Carboniferous Mazon Creek Formation of Illinois. Undisputed cubozoan fossils were previously unknown from the early Cambrian; by that time probably all representatives of the living marine phyla, especially those of basal animals, should have evolved. METHODS: Microscopic fossils were recovered from a phosphatic limestone in the Lower Cambrian Kuanchuanpu Formation of South China using traditional acetic-acid maceration. Seven of the pre-hatched pentamerous cubozoan embryos, each of which bears five pairs of subumbrellar tentacle buds, were analyzed in detail through computed microtomography (Micro-CT and scanning electron microscopy (SEM without coating. RESULTS: The figured microscopic fossils are unequivocal pre-hatching embryos based on their spherical fertilization envelope and the enclosed soft-tissue that has preserved key anatomical features arranged in perfect pentaradial symmetry, allowing detailed comparison with modern cnidarians, especially medusozoans. A combination of features, such as the claustrum, gonad-lamella, suspensorium and velarium suspended by the frenula, occur exclusively in the gastrovascular system of extant cubozoans, indicating a cubozoan affinity for these fossils. Additionally, the interior anatomy of these embryonic cubozoan fossils unprecedentedly exhibits the development of many new septum-derived lamellae and well-partitioned gastric pockets unknown in living cubozoans, implying that ancestral cubozoans had already evolved highly specialized structures displaying unexpected complexity at the dawn of the Cambrian. The well-developed endodermic lamellae and gastric pockets developed in the late embryonic stages of these cubozoan fossils are comparable with

  4. Cambrian and ordovician systems around the pacific basin (part 3)

    1987-10-25

    This report describes the history of the studies made about old rocks and Cambrian and Ordovician Systems in North America. In last century, development of the Pre-Canbrian stratigraphy and mineral resources was started in Canada, while the New York System was instituted in the middle and east areas of North America, and it was later correlated to the European sequence. Walcott who published many reports including the vental anatomy of trilobites made invaluable contribution on the study of Cambrian geology. The Cambro-Ordovician faunas which distributed in the Appalachian mountains and further westerly beyond the lower Mississipy river were related to the European ones. The systems in the Cordilleran geosyncline was also described. Stratigraphy in the western sites is followed on the Alaskan faunas in the north which were allied to the Siberian faunas and later to the Eastern Asiatic ones. Lastly, Circum-Pacific Cambro-Ordovician belt was taken up. The eastern side of the Circum-Pacific Cambrian belt belonged to Olenellian province, and the other side constituted the Redlichia province. (2 figs, 5 tabs, 101 refs)

  5. Lower Cambrian biogeography and the prehistory of early animals

    Energy Technology Data Exchange (ETDEWEB)

    Signor, P.W. (Univ. of California, Davis (United States))

    1991-02-01

    Biogeographic distributions of animals reflect the complex interplay of biological and physical processes acting over geological time. In particular, plate tectonics and the evolution of lineages within clades play fundamental roles in determining faunal distributions. Ranges expand through vicariant events or dispersal and contract through local and regional extinctions. Vicariance promotes the evolutionary divergence of closely related lineages. Viewed as historical phenomena, biogeographic distributions can be employed to infer prior tectonic and evolutionary events. For example, the existence of modern marine faunal provinces reflects the interaction of evolution and plate tectonics. The Proterozoic history of skeletogenous organisms (and their ancestors) is a contentious subject, with many authors arguing that skeletogenous clades have no significant prehistory before their appearance in the fossil record. The existence of trilobite provinces dominated by different suborders, for example, suggests the trilobites evolved and dispersed, or were separated by plate movement, and then evolved independently for an extended period prior to their appearance in the fossil record. Similar arguments can be applied to other groups. The paleobiogeographic distribution of organisms also provides useful insights into late Proterozoic and Early Cambrian paleogeography. The provincial distribution of Early Cambrian taxa suggests that the putative Proterozoic supercontinent, if it existed, began to separate well before the Early Cambrian. Separate provinces would not have evolved had the various plates remained united. Therefore, the dawn of the Phanerozoic could not have coincided with the breakup of the Proterozoic supercontinent.

  6. Armored kinorhynch-like scalidophoran animals from the early Cambrian.

    Morphology-based phylogenetic analyses support the monophyly of the Scalidophora (Kinorhyncha, Loricifera, Priapulida) and Nematoida (Nematoda, Nematomorpha), together constituting the monophyletic Cycloneuralia that is the sister group of the Panarthropoda. Kinorhynchs are unique among living cycloneuralians in having a segmented body with repeated cuticular plates, longitudinal muscles, dorsoventral muscles, and ganglia. Molecular clock estimates suggest that kinorhynchs may have diverged in the Ediacaran Period. Remarkably, no kinorhynch fossils have been discovered, in sharp contrast to priapulids and loriciferans that are represented by numerous Cambrian fossils. Here we describe several early Cambrian (~535 million years old) kinorhynch-like fossils, including the new species Eokinorhynchus rarus and two unnamed but related forms. E. rarus has characteristic scalidophoran features, including an introvert with pentaradially arranged hollow scalids. Its trunk bears at least 20 annuli each consisting of numerous small rectangular plates, and is armored with five pairs of large and bilaterally placed sclerites. Its trunk annuli are reminiscent of the epidermis segments of kinorhynchs. A phylogenetic analysis resolves E. rarus as a stem-group kinorhynch. Thus, the fossil record confirms that all three scalidophoran phyla diverged no later than the Cambrian Period.

  7. Antarctica, supercontinents and the palaeogeography of the Cambrian 'explosion'

    Science.gov (United States)

    Dalziel, Ian

    2014-05-01

    Laurentia is bordered by latest Precambrian-Cambrian rifted margins and must therefore have been located within a Precambrian supercontinent. Geochronologic and geochemical evidence indicates that it was attached to parts of the East Antarctic craton within the Rodinian supercontinent in the late Mesoproterozoic. The Mawson craton of Antarctica rifted from the proto-Pacific margin of Laurentia during the Neooproterozoic, colliding with the present 'southern cone' of Laurentia at ~600 Ma along the Shackleton Range suture zone as Gondwana and Laurentia amalgamated to form the ephemeral Pannotia supercontinental assembly at the end of the Precambrian. The abrupt appearance of almost all animal phyla in the fossil record is often colloquially referred to as the Cambrian 'explosion' of life on Earth. It is also named 'Darwin's dilemma,' as he appreciated that this seemingly mysterious event posed a major problem for his theory of evolution by natural selection. It coincided with a time of major marine transgression over all the continents. Although the metazoan 'explosion' is now seen as more protracted than formerly recognized, it is still regarded one of the most critical events in the history of the biosphere. One of the most striking aspects of the earliest Cambrian fossils is geographic differentiation. In particular, the first benthic trilobite faunas on Laurentia, ancestral North America, and the newly amalgamated southern supercontinent of Gondwana are distinctly different. This has led to the suggestion of an unknown vicariant event intervening between an ancestral trilobite clade and higher members that are represented in the fossil record, possibly one related to the breakup of a supercontinent. Igneous rocks along the Panthalassic margin of Gondwana, including South America, southernmost Africa and the Ellsworth-Whitmore crustal block of Antarctica, and along the proto-Appalachian margin of Laurentia indicate that final separation of Laurentia from

  8. Relationship between the Neoproterozoic snowball Earth and Cambrian explosion

    Science.gov (United States)

    Maruyama, S.; Yoshihara, A.; Isozaki, Y.

    2007-12-01

    Origin of snowball Earth has been debated in terms of greenhouse gas (e.g., Hoffman and Schrag), obliqueness of Earth's rotation axis (Williams, 1975), true polar wander (Evans, 2003), Galactic cosmic ray radiation (Shaviv and Veizer, 2003; Svensmark, 2006), or weakened geomagnetism (Maruyama and Yoshihara, 2003). A major difficulty for the greenhouse gas hypothesis is the on-off switch causing decrease and increase of appropriate amounts of CO2 by plume- and plate tectonics, and also in available amount of CO2 in atmosphere to be consistent with the observations. In contrast, the cosmic ray radiation models due to the star burst peaked at 2.5- 2.1 Ga and 1.4-0.8 Ga can explain on-off switch more easily than the greenhouse gas model. Cosmic ray radiations, however, must be modified by the geomagnetic intensity, fluctuating 150"% to cause the snowball Earth. Time difference between the Neoproterozoic snowball Earth and Cambrian explosion is as large as 250 millions years, and this refuses their direct close-relationship. Role of frequent mass extinctions, i.e., 8 times during 100 m.y. from 585 Ma to 488 Ma, during the Ediacaran and Cambrian, has been proposed (Zhu et al., 2007). This frequency is one order of magnitude higher compared to that in the post-Ordovician time. Yet, the Cambrian explosion cannot be explained by mass extinction which replaced the vacant niches shortly after the mass extinction and never created a new animal with a new body plan. A new model proposed herein is derived from weakened geomagnetism and resultant extensive cosmic radiation to alter gene and genome for a long period over advancement of low magnetic intensity and cosmic radiations (Svensmark, 2006) from 1.2-0.8Ga. As to the new body plans of animals, it took an appreciably long time to prepare all 34 genometypes before the apparent Cambrian explosion.

    The objective of this paper is to describe, the journey for the development of power generation through source of wind, and to establish the elements that must be overcome to enable implementation of wind projects in Uruguay. For its achievement will be a descriptive framework that has been developing wind energy in the region, particularly as it relates to the Argentine case, as opposed to activities in the Uruguay in the same period. Carry out a review and interrelation between the greenhouse effect, the internalization of environmental costs and sustainable development concept, as well as analyzing the input of emissions to the environment by issuing sector. It will describe, briefly, the composition of the matrix of power generation in Uruguay. Subsequently analyzing the history of wind energy in Uruguay, the results of this experience and will be explored regarding the existence or absence of incentives within the existing legal framework. Finally, described the wind power perspectives in Uruguay and propound what will be the key steps and tools necessary to facilitate the development of this source of generation in the country.

    The Dom Feliciano Belt (DFB) stretches for ca. 1,200 km along southeastern Brazil and eastern Uruguay, with an average width of 150 km. From its northern limit in Santa Catarina to its termination m Uruguay, DFB is internally organized according three crustal segments characterized, from southeast to northwest, by a Granitoid belt (calci-alkaline to alkaline granitoid rocks deformed to different degrees); a Schist belt (volcano-sedimentary rocks metamorphosed from green schist to amphibolite facies), and a Fore land belt (sedimentary and anchimetamorphic volcanic rocks), the latter situated between the Schist belt and the old western terranes. Despite discontinuously covered by younger sediments, the continuity of these three segments is suggested by the similar lithotypes and structural characteristics, as well as by the gravimetric geophysical signature.In this work, DBF is interpreted as the product of successive subduction s and collisions related to the agglutination of different terranes generated or intensely reworked from the Neoproterozoic to the Cambrian, during the Brasiliano and Rio Doce orogenesis, with maximum time starting at 900 Ma (opening of the Adamastor Ocean) and ending at 530 Ma (deformation of the fore land basins) related to the tecto no-magmatic events associated with the formation of the Western Gondwana.Besides the Neoproterozoic DFB and its fore land, the Rio de la Plata Craton and the Luis Alves Microplate, constituted by Paleoproterozoic gneissic-migmatitic rocks, two other tectonic units can be recognized in southeastern Brazil and eastern Uruguay: the Sao Gabriel Block (RS) where Neoproterozoic juvenile material can be characterized in regional scale (in great part associated with an island are), and the Punta del Este Terrane, which presents, in southern Uruguay, an ortho gneiss basement with ages around 1,000 Ma and a meta sedimentary cover (Rocha Group), which can correspond in the South-American portion, to the Namaqua and Gariep

    Full Text Available The controversy about a Cambrian "explosion" of morphological disparity (followed by decimation, cladogenesis and fossilization is of central importance for the history of life. This paper revisits the controversy (with emphasis in onychophorans, which include emblematic organisms such as Hallucigenia, presents new data about the Chengjiang (Cambrian of China faunal community and compares it and the Burgess Shale (Cambrian of Canada with an ecologically similar but modern tropical marine site where onychophorans are absent, and with a modern neotropical terrestrial onychophoran community. Biovolume was estimated from material collected in Costa Rica and morphometric measurements were made on enlarged images of fossils. Cambrian tropical mudflats were characterized by the adaptive radiation of two contrasting groups: the vagile arthropods and the sessile poriferans. Arthropods were later replaced as the dominant benthic taxon by polychaetes. Vagility and the exoskeleton may explain the success of arthropods from the Cambrian to the modern marine and terrestrial communities, both in population and biovolume. Food ecological displacement was apparent in the B. Shale, but not in Chengjiang or the terrestrial community. When only hard parts were preserved, marine and terrestrial fossil deposits of tropical origin are even less representative than deposits produced by temperate taxa, Chengjiang being an exception. Nutrient limitations might explain why deposit feeding is less important in terrestrial onychophoran communities, where carnivory, scavenging and omnivory (associated with high motility and life over the substrate became more important. Fossil morphometry supports the interpretation of "lobopod animals" as onychophorans, whose abundance in Chengjiang was equal to their abundance in modern communities. The extinction of marine onychophorans may reflect domination of the infaunal habitat by polychaetes. We conclude that (1 a mature ecological

    The Cambrian Tamdroust and Bab n'Ali Volcanic Complexes represent two magmatic episodes developed in the latest Ediacaran-Cambrian Atlas Rift of Morocco. Their rifting pulses were accompanied by accumulation of volcanosedimentary edifices (dominated by effusive lava flows in the former and explosive acidic aprons in the latter) associated with active tilting and uplift. Sealing of their peneplaned horst-and-graben palaeotopographies led to the onset of distinct onlapping geometries and angular discordances capping eroded basements ranging from the Ediacaran Ouarzazate Supergroup to the Cambrian Asrir Formation. Previous interpretations of these discordances as pull-apart or compressive events are revised here and reinterpreted in an extensional (rifting) context associated with active volcanism. The record of erosive unconformities, stratigraphic gaps, condensed beds and onlapping patterns across the traditional "lower-middle Cambrian" (or Cambrian Series 2-3) transition of the Atlas Rift must be taken into consideration for global chronostratigraphic correlation based on their trilobite content.

    Full Text Available In this paper domestic tourism in Uruguay is analyzed by introducing an Origin-Destination matrix approach, and an attraction coefficient is calculated. We show that Montevideo is an attractive destination to every department except itself (even if it emits more trips than it receives, and the Southeast region is the main destination. Another important outcome is the importance of intra-regional patterns, associated to trips to bordering departments. Findings provide destination managers with practical knowledge, useful for reducing seasonality and attracting more domestic tourists throughout the year, as well as to deliver a better service offer, that attracts both usual visitors and new ones from competitive destinations.

    Full Text Available Cyanobacterial blooms are a worldwide environmental problem. This phenomenon is typically associated with eutrophication (nutrient enrichment and changes in hydrology. In this study we analysed the distribution of planktonic cyanobacteria in Uruguay and their toxins (microcystin, saxitoxin and cylindrospermopsin, working with an interagency team (OSE, DINAMA, IM, University of the Republic and IIBCE. An historical data base (n = 3061 for 64 ecosystems, years 1980-2014 was generated. Differences between lotic and lentic ecosystems were found in terms of chlorophyll a and nutrient concentrations, usually indicating eutrophication. Two geo-referenced maps for the country were generated with cyanobacteria biomass indicators and the most relevant toxin (microcystin, according to risk levels suggested by the World Health Organization for recreational waters. The areas of greatest risk of exposure were the reservoirs of large rivers (Uruguay and Río Negro and Río de la Plata beaches. In the second part of the study, up to 20 mg L-1of microcystin was quantified in bloom (scum samples, as well as the presence of genes that suggest more microcystin varieties, potentially with greater toxicity. This study provides basic information about the distribution of cyanobacteria in Uruguayan freshwaters that will be useful for national monitoring programs and scientific research.

    Since Uruguay did not have an study on X-ray equipment, students of Radiation Protection course (RP) made this field work throughout the country. The objective is to obtain information on the number and kind of X-ray radiodiagnostic equipment. Some of the results are: there are 666 radiodiagnostic equipment. The ratio of population to equipment is 4.515 to 1 in the capital and the mean rate in the rest of the country is 4.383 to one, with a minimum of 1.707 and a maximum of 8.220. The Public Health Ministry (MSP) and the Instituciones de Asistencia Medica Colectiva (a kind of private heath assurance) (IAMC) have less equipment in the capital than in the rest of the country. The 37% of the capital population receives assistance through the IAMC , with a 42.5 % of the equipment. Uruguay except the capital has 18 districts and 17 computed tomography equipment, from which only 3 belong to the MSP. Five districts do not have any. In Montevideo, there are 11.500 females over forty years of age per X-ray mammography equipment, and this relation in the rest of the country is 13.900. There are 21 X-ray Interventional radiology equipment, 16 of them are in the capital. Is from relating the radiodiagnostic equipment, the population and the procedures, that quality assistance indicators emerge. This owns high importance on the way to create a RP National Programme.

    Full Text Available Natural grasslands in the basaltic region of Uruguay are threatened by an increase in stocking rates and changes in land use. To assess the effect of grazing intensification, plant functional types are proposed as simple tools to aid the monitoring and management of vegetation. In the present study we evaluated the effect of stocking rate increase at community level taking into account plant traits of 23 dominant perennial grass species. In order to identify plant functional types, we determined the grazing response in an experiment with two wethers stocking rates (0.78 and 1.56 livestock units ha-1 quantifying species cover and traits values. Leaf dry matter content (LDMC and specific leaf area (SLA were the traits that best described the perennial grasses response to the stocking rate increase and therefore are suggested to be used as functional markers. Three functional types were identified. Low stocking rates were related to functional type A (tall, warm season species with low SLA and high LDMC and functional type B (tall, cool-season species, with intermediate levels of leaf traits. On the other hand, high stocking rate encouraged functional type C (prostrate, warm season species, with high SLA and low LDMC. The classification of a highly diverse community into three functional types and the selection of traits as functional markers candidates is an innovative approach to develop simple and general methods to diagnosis the state of basaltic grasslands in Uruguay and to advise on its management.Las praderas naturales de la region bas áltica de Uruguay están amenazadas por el incremento de la carga animal y cambios en el uso del suelo.

Mediante el análisis de la dimensión simbólica del mundo social agrario estudiaremos las prácticas discursivas de las Gremiales Ganaderas - Asociación Rural del Uruguay y Federación Rural - como parte central de su estrategia simbólica para mantener su hegemonía en el campo social agrario. En este sentido, creemos que la construcción social del territorio en nuestro país se asienta en la forma de percepción impuesta por el poder simbólico de este grupo que ha hecho de sus formas particulares de apropiación y uso de la tierra la única forma posible y legítima de utilización de los recursos naturales. Para el análisis de las prácticas discursivas partimos del supuesto de que las organizaciones sociales, gremiales y corporativas están siempre inmersas en luchas simbólicas, ya que en ellas está en juego la realización objetiva de sus intereses a largo plazo. Utilizando los términos de Merton, podríamos afirmar que, más allá de la función manifiesta de una organización - gremial, comercial, profesional -, siempre hay una función latente que procura imponer a sus adversarios y a la opinión pública la "visión del mundo" propia del grupo que representa. En consecuencia, en las prácticas discursivas de estos agentes podremos encontrar claramente expresado su poder, sus alianzas, sus conflictos, lo que nos permite acceder a la comprensión de su estrategia simbólica de reproducción social.This article will try to study the broad influence and power maintained by large landowners and their associations since over a century ago in Uruguay.

  9. A review of the Late Cambrian (Furongian) palaeogeography in the western Mediterranean region, NW Gondwana

    The Cambrian-Ordovician transition of the western Mediterranean region (NW Gondwana) is characterized by the record of major erosive unconformities with gaps that range from a chronostratigraphic stage to a series. The hiatii are diachronous and involved progressively younger strata along the Gondwanan margin, from SW (Morocco) to NE (Montagne Noire). They can be related to development of a multi-stage rifting (further North), currently connected to the opening of the Rheic Ocean, and concomitant erosion on southern rift shoulders. The platforms of this margin of Gondwana occupied temperate-water, mid latitudes and were dominated by siliciclastic sedimentation, while carbonate factories were only episodically active in the Montagne-Noire platform. The Upper Cambrian is devoid of significant gaps in the southern Montagne Noire and the Iberian Chains. There, the sedimentation took place in a transgressive-dominated depositional system, with common offshore deposits and clayey substrates, and was bracketed by two major regressive trends. The Late Cambrian is also associated with the record of volcanic activity ( e.g., in the Cantabrian and Ossa-Morena zones, and the northern Montagne Noire), and widespread development of a tectonic instability that led to the episodic establishment of palaeotopographies and record of slope-related facies associations. Several immigration events are recognized throughout the latest Middle Cambrian, Late Cambrian and Tremadocian. The trilobites show a stepwise replacement of Acado-Baltic-type families ( e.g., the conocoryphid-paradoxidid-solenopleurid assemblage) characterized by: (i) a late Languedocian (latest Middle Cambrian) co-occurrence of Middle Cambrian trilobite families with the first anomocarid, dorypygid and proasaphiscid invaders; (ii) a Late Cambrian immigration replacing previous faunas, composed of trilobites (aphelaspidids, catillicephalids, ceratopygids, damesellids, eulomids, idahoiids, linchakephalids, lisariids

    The Cambrian Tamdroust and Bab n’Ali Volcanic Complexes represent two magmatic episodes developed in the latest Ediacaran–Cambrian Atlas Rift of Morocco. Their rifting pulses were accompanied by accumulation of volcanosedimentary edifices (dominated by effusive lava flows in the former and explosive acidic aprons in the latter) associated with active tilting and uplift. Sealing of their peneplaned horst-and-graben palaeotopographies led to the onset of distinct onlapping geometrie...

  11. The sedimentological characteristics of microbialites of the Cambrian in the vicinity of Beijing, China

    Full Text Available With oil and gas exploration transferring to deeper and more ancient marine strata, more researches have been conducted about the Meso–Neoproterozoic and Cambrian microbial carbonate rocks by petroleum geologists. The Cambrian deposits experienced the first transgression of the Paleozoic, with shallow marine facies depositing in most areas, which are favorable for different kinds of biological reproduction. The Lower Cambrian in Beijing area is lithologically dominated by purple red shales interbedded with limestones, the Middle Cambrian is mainly composed of thick oolitic limestones, and the Upper Cambrian consists of thin limestones and flat-pebble conglomerates. Two beds of microbial carbonate rocks were discovered in the Cambrian outcrops in the vicinity of Beijing. One is from the Zhangxia Formation of Middle Cambrian, and the other is from the Gushan Formation of Upper Cambrian. The microbialites are characterized by combination of multiple stromatolites forming different bioherms. The bioherms are mostly in oval shape and with different sizes, which are 3–4 m long, and 1–3 m high. The surrounding strata beneath the bioherms are oolitic limestones. A central core of flat-pebble conglomerates occurred within each bioherm. Wavy or columnar stromatolites grow on the basis of flat-pebble conglomerates, with dentate erosional surfaces. The bioherm carbonate rocks are interpreted as products from a deep ramp sedimentary environment where potential oil and gas reservoirs can be found. The analysis of sedimentological characteristics of bioherm carbonate rocks and its lithofacies palaeogeography has significant implication for petroleum exploration. Research on geological record of microbialites is beneficial to investigating the Earth evolution, biodiversity, palaeoenvironment and palaeoclimate change, as well as biological extinction event during geological transitions. It also gives warning to human beings of modern biological crisis.

  12. Traditional application of slates in Uruguay

    2017-04-01

    Commercial slates in Uruguay are represented by dolomitic and pelitic slates, which are known in the local market with the generic name of "piedra laja". The dolomitic slates, or more precisely the "slaty dolomitic semipelites" and "slaty dolomitic metacarbonate rocks" (following the nomenclature of the British Geological Survey for metamorphic rocks, Robertson 1999), dominates the production since 1960. The mining started in a quarry called "Libro Gigante", which means "giant book" in Spanish, as the slaty cleavage of these rocks is almost vertical, which resembles a book when looked from far away. These slates integrate the Lavalleja Group, a unit that comprises the schist belt of the Neoproterozoic Dom Feliciano Belt that crops out in south-eastern Uruguay. According to Morales Demarco et al (2013), there are two active slate mining districts in this region: the northern, called "Arroyo Minas Viejas Mining District", from where light grey, light and dark green and green-red slate varieties are mined, and the southern called "Arroyo Mataojo Mining District" and where only dark grey slates are extracted. Few kilometres eastern from these districts, and still in Lavalleja Group, a quarry of slaty dolomitic pelite is found with sporadic production. Far to the east, the slaty muscovitic pelites of Rocha Group are mined from one quarry in "Puntas del Chafalote". The traditional applications of these slates in the country are as façade cladding and floor slabs, both indoor and outdoor. The potential use of the dolomitic slates as roofing slates has been investigated and discarded by Morales Demarco et al (2013), as the slabs resulting from splitting are too thick (0.5 to 2 cm) and thus too heavy for this application. The parameter that controls the fissility of slates is the mass value (Bentz and Martini, 1968; DIN EN 12326-2, 2000) and is very important to determine their potential applications. It takes into account the number of mica layers per mm and the average

    The western cratonic domains in Uruguay are divided into three major units: Piedra Alta Terrane, Valentines Block and Pavas Block. Piedra Alta Terrane lacks of evidence of Neoproterozoic orogenesis (deformation, metamorphism or magmatism). Sarandí del Yi - Arroyo Solís Grande shear zone, separates it from Valentines Block. Valentines Block is separated from Pavas Block by Cueva del Tigre shear zone. Magmatic rocks with different ages, compositions and emplacements occur all over the Piedra Alta Terrane distributed in three metamorphic belts (Arroyo Grande, San José and Montevideo) as well as in the Central Gneissic-Migmatitic Complex (Figure 1). Samples from the Gneissic-Migmatitic complex, late tectonic granitoids and basic rocks associated to the metamorphic belts were analyzed using Rb/Sr, U/Pb, K/Ar and Sm/Nd methodologies. The age ranges obtained for granitoids

    Asthma mortality rates have increased worldwide during the past several years despite the increased availability of new and effective medications. Few studies show reliable data from Latin American countries. To determine asthma mortality rates from 1984 to 1998 and to relate mortality to sales of asthma medications. We conducted a retrospective epidemiologic study in the total population of Uruguay. Data were obtained from the Department of Statistics of the Ministry of Public Health. Trends in mortality rates were analyzed using linear regression procedures. Spearman rank correlations were used to relate mortality rates to sales of asthma medications. The mean overall mortality rate was 5.10 per 100,000 during the period 1984 to 1998, (range 6.08 to 3.39) and showed a decreasing trend (P = 0.001). During the period 1995 to 1998, a more pronounced decrease was observed (mean mortality rate, 4.10 per 100,000). In the 5- to 34-year-old age group the mean mortality rate was 0.43 (range 0.65 to 0.13). Similarly, the mortality rate in this age group decreased particularly in the 1994 to 1998 period (mean 0.19; P = 0.005). Finally, the mortality rate was inversely correlated with sales of inhaled corticosteroids; for the overall mortality rate, p = -0.71, P = 0.003; for 5- to 34-year-old age group, p = -0.63, P = 0.01. Although mortality attributable to asthma seems to be decreasing, the overall mortality rate is still high compared with more economically developed countries. A more pronounced decrease in asthma mortality has been seen in the 5- to 34-year-old group. At present, Uruguay is a Latin American country with a low rate of asthma mortality. This is probably related to the use of new therapies to treat asthma.

    1985-01-01

    The base of the Eurekia apopsis Subzone of the Saukia Zone, slightly below the present Cambrian-Ordovician boundary, has been interpreted as a biomere extinction crisis for trilobites and conodonts. This boundary can be recognized to within two centimeters in platform carbonates in Utah, Nevada, Texas, and Oklahoma. Regional stratigraphy in West Utah reveals that this extinction horizon occurs within a shoaling upward sequence in which sedimentation was predominantly episodic. Shallow subtidal sedimentation, producing bioturbated mixed-skeletal wackestones and graded intraclastic grainsupportstones (tempestites), shifted to peritidal sedimentation through the boundary interval and for the duration of the E. apopsis Subzone. Associated lithofacies include sponge-dominated thrombolite mounds with tidal channels, sublittoral stromatolite reefs, and a restricted marine lagoon. The base of the E. apopsis Subzone in West Utah is a sharp contact but is interpreted as neither a disconformity nor a surface of subaerial exposure. In Texas, this boundary is a planar disconformity between biosparites. The bed underlying this surface displays features that reflect wholesale aragonite dissolution followed by two stages of inferred meteroic phreatic cementation. The surface is well washed and provided a clean substrate for epitaxial cementation across the boundary. The overlying basal strata of the E. apopsis Subzone are cemented with marine phreatic non-ferroan calcite and contain faunas that are strikingly dissimilar to those below.

    2010-01-01

    Objective: To analyze trends in cancer mortality in Uruguay in the period 1989-2008. Methodology: The National Cancer Registry (NCR) collects information from cancer mortality from the death certificates: 147 631 deaths were identified in the period from cancer, which was recorded topography, sex and age. They were calculated for each year mortality rates adjusted for age (TMAE) using as standard the world population. Trends were assessed using the method and calculated the joinpoint Estimated Annual Percent Change (ESPP). Results: The TMAE presents downward trend in both sexes (ESPP = significant -0.60 in men and -0.49 In women). In the period studied, mortality presented decreasing trend when it comes to cancer breast cancer in women (ESPP -0.79, significant), and increased for prostate cancer (ESPP = 0.70) and kidney (ESPP = 1.82 and 1.71 in men and women respectively). As regards the digestive system decreased mortality observed for esophageal cancer (ESPP in = -1.93 men and women = -1.78) and stomach (ESPP = -2.22 men and women -2.24 ). Mortality for cancer of colorectum is stable in men (ESPP = 0.35 No significant (NS)) and shows a decline slight but steady in women (ESPP -0.5). As for cancers that show strong association with smoking, decreased mortality observed lung and laryngeal cancer in men (ESPP = -1.11 and -2.05 respectively), confirming the trend found between 1990 and 2001; in women there is increased mortality from lung cancer (ESPP = 2.76) that is not accompanied by increased mortality from laryngeal cancer (-0.1 ESPP = NS). Mortality from cancers oral cavity and pharynx is stable, but in women a significant increase (ESPP = 1.84) is observed when the oral cavity is analyzed in isolation (lip, tongue, gums, palate). As cervical cancer, mortality trends in 20 years is to increase (ESPP = 1.14), however, if consider only the past decade, mortality appears stabilized (ESPP = 0.57 NS). Conclusions: The overall trend of cancer mortality (all sites

    2010-01-01

    Objective: To evaluate the incidence of TPM in Uruguay through the RNC data. Materials and Methods: Of the incident cases registered in 2008, they were selected those presented in the database prior cancer registry. The are excluded in situ of the cervix and non-melanoma skin carcinomas. Results: At the present time are entered to the the base of the RNC 11859 new cases of cancer incidents in 2008. Of these 566 (4.7%) had a prior record of criteria selection where 308 were women and 258 men. Of these, 450 met the IACR / IARC criteria (*). (Two topographies and / or different histologies). The median age of first tumor presentation was 65 years (22-89). The second 71 years (27-94). The median of the difference was about 4 years Analyzed by gender: Breast cancer (CM) was the most frequent tumor in women, cancer as first (142) and as second (85). The most common associations (excluding Bilateral) CM, CM with gynecological tumors were (TG: ovarian and corpus uteri) 11% CM and colo-rectum (CCR) (9.4%), TG and CCR (5%). 26% of female cases occurred in two hormone-dependent tumors (CM and CM bilateral or TG). In men prostate cancer (PC) is the most common tumor as first cancer (76) but the CCR is the most frequent and second (56). The association comprises CP-CCR 15% of cases and CP association and transitional tumors (TT) 10%. The association of two or more snuff-dependent tumors was observed in 8% of cases. When discriminated by sex in men is 13%, amounting to 19% if taking into account the multiple TT, while in women corresponds to 2%. Conclusions: The profile presentation of TPM in the RNC of Uruguay is similar to that reported other records in both frequency (depending on the criteria that defined) and associated type of tumors. The most frequent associations also They are similar to those observed by other authors: CCR, CM and TG women and CCR, and CP TT in men. The association of tumors are also observed with risk common factors: in women hormonal factors linked to

    Reducing fossil fuel consumption and increasing energy efficiency of agricultural systems may result in environmental and economic benefits. The aim of this study was to analyze dairy production systems from an energy perspective, to identify the main variables affecting energy efficiency and fossil energy consumption, through a model of inputs and outputs. The model included as inputs energy costs of food, labor, electricity, agrochemicals, fuels and machinery, and as outputs dairy and meat production. We analyzed a database of 30 dairy farms from southern Uruguay, from the Cooperative Nacional de Product ores de Leche (Conaprole), organized in three strata based on their dairy productivity per hectare. The fossil energy use was 2.40, 3.63 y 3.80 MJ.l-1 for productivity strata low, medium and high respectively (P<0.01). Energy efficiency averages were 1.40, 0.90 y 0.86 for the same strata (P<0.01). Fossil energy of agrochemicals and fuel accounted for more than 80% of the energy consumed in the three strata. The greater the percentage of concentrate in the diet, the lower energy efficiency (P<0.01). These results suggest the existence of a negative relationship between the intensification of dairy production and energy efficiency

    In the last two decades, great progress has been made in the geochronological, chrono- and chemostratigraphic control of the Neoproterozoic and Cambrian from the Anti-Atlas Ranges and the Ouzellagh promontory (High Atlas). As a result, the Neoproterozoic is lithostratigraphically subdivided into: (i) the Lkest-Taghdout Group (broadly interpreted at c. 800–690 Ma) representative of rift-to-passive margin conditions on the northern West African craton; (ii) the Iriri (c. 760–740 Ma), Bou Azzer (c. 762–697 Ma) and Saghro (c. 760?–610 Ma) groups, the overlying Anezi, Bou Salda, Dadès and Tiddiline formations localized in fault-grabens, and the Ouarzazate Supergroup (c. 615–548 Ma), which form a succession of volcanosedimentary complexes recording the onset of the Pan-African orogeny and its aftermath; and (iii) the Taroudant (the Ediacaran–Cambrian boundary lying in the Tifnout Member of the Adoudou Formation), Tata, Feijas Internes and Tabanite groups that have recorded development of the late Ediacaran–Cambrian Atlas Rift. Recent discussions of Moroccan strata to select new global GSSPs by the International Subcommissions on Ediacaran and Cambrian Stratigraphy have raised the stratigraphic interest in this region. A revised and updated stratigraphic framework is proposed here to assist the tasks of both subcommissions and to fuel future discussions focused on different geological aspects of the Neoproterozoic–Cambrian time span.

    2000-01-01

    Bovine respiratory syncytial virus (BRSV) is a major cause of respiratory disease in calves resulting in a substantial economic loss for the cattle industry worldwide. In order to determine the presence of BRSV in Uruguay, an immunoenzymatic test was set up, using a recombinant BRSV nucleocapsid (N) protein as the antigen. The N protein was produced in Sf9 insect cells by a recombinant baculovirus expressing the N protein. Serum samples collected from one hundred cattle from four different geographic regions of Uruguay were analyzed. Antibodies against the N protein of BRSV were detected in 95% of the serum samples analyzed. These results show for the first time the presence of BRSV antibodies and suggest a widespread BRSV infection in the cattle population of Uruguay.

He is usual that many institutions of education of Uruguay do not have possibility of acceding to our Museum for economic reasons for which what we propose it is the accomplishment of a crossed CD with one virtual visit to the Geology of Uruguay

  12. The onset of the 'Ordovician Plankton Revolution' in the late Cambrian

    2016-01-01

    Positive Carbon Isotope Excursion δ13Ccarb (SPICE) event in the late Cambrian (Paibian Stage, Furongian Series) has been related to a major increase in atmospheric O2 (from 10-18% to some 20 - 29%) and to increased oceanic nutrient availability. Here we analyze the diversification of the planktonic groups...... during the late Cambrian and Early Ordovician, in particular in relation to the SPICE event. Our analyses include the changing diversities of the phytoplankton (acritarchs), diverse groups of zooplankton (e.g., radiolarians, graptolites, chitinozoans) and the switch to a planktonic mode of life of fossil...... of the different planktonic organisms can be related directly to the SPICE event. However, a long term (10-20millionyears) oxygenation pulse related to the SPICE event might have fuelled the explosion of phytoplankton diversity observed in the latest Cambrian-Early Ordovician that led to completely modified...

    The Permian megafloras of Uruguay. A synthesis. An analysis of the impression and fossil wood floras from the Permian of Uruguay is given through a series of Tables. These show : (1) the list of taxa, (2) anatomical characters of the woods, (3) data on the microfloral associations, (4) paleoenvironmental information and (5) comparisons with contemporaneous Gondwana floras. The evolutionary degree of the woods is briefly analyzed where they correspond to the so-called ''transition xilotaphofloras'' as they present typical Paleozoic anatomical characters but with secondary xylem of more advanced characteristics.

    Full Text Available Este trabajo introduce el uso de grafos en el análisis de los determinantes del gasto de los turistas y lo aplica al estudio del comportamiento de los pasajeros de cruceros que desembarcan en Uruguay en los puertos de Montevideo y Punta del Este. Este enfoque ofrece un abordaje alternativo a los usualmente empleados para analizar los determinantes del gasto turístico al introducir una representación gráfica que permite sintetizar y visualizar las relaciones entre el conjunto de variables que caracterizan a los turistas o grupos de turistas y los determinantes de su nivel de gasto. En particular, la metodología permite representar las relaciones de dependencia entre variables (entre nodos adyacentes e independencias condicionadas (entre nodos no adyacentes. Para su aplicación, se consideran datos individuales de las encuestas realizadas a cruceristas correspondientes a la temporada de cruceros comprendida entre noviembre de 2014 y abril de 2015, ambos incluidos, en Uruguay. Se estudia la existencia de dependencias de las variables relativas a registrar el gasto de los cruceristas con otras variables (sociodemográficas, de contexto, etc.. El estudio muestra que las variables que mejor explican el comportamiento de los visitantes son las vinculadas al puerto de desembarco y al gasto.

  16. Il regionalismo commerciale dopo l'Uruguay Round (Commercial regionalism after the Uruguay Round

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available The attempts by a number of countries to partially or totally liberalise their trade on a discriminatory basis have long been documented. Despite the wide spread of the GATT in both geographical and temporal terms, regionalism has never easily co-existed with commercial multilateralism. The Uruguay Round has taken place in a period in which several key countries have radically changed trade policies. In this light, the search for a new balance between the multilateralism de jure and the regionalism de facto practiced by many members of the GATT took on importance as a test of their intentions to continue or not with the existing multilateral order or rather to modify it in a regional sense. This paper reviews the problems of coexistence between regionalism and multilateralism in the international trade order and demonstrates how few concrete conclusions can be drawn from an examination of both the theory and the empirical evidence.JEL: F13

  17. Detrital zircons from samples of five Neo proterozoic sandstone units deposited on Uruguay and Argentina: about evolution of paleographic Rio de la Plata craton

    Gaucher, C.; Poire, D.G.; Pamoukaghlian, K.; Gomez Peral, L.; Finney, S.; Valencia, V.; Blanco, G.

    2007-01-01

    We report U-Pb ages of detrital zircons from samples of five Neoproterozoic sandstone units deposited on the Rio de la Plata Craton (RPC) in Uruguay and Argentina. Quartz-arenites of the Piedras de Afilar Formation show typical Transamazonian ages, with peaks at 2.00-2.07, 1.87 and 1.78 Ga. However, the most important zircon population is Mesoproterozoic, showing maxima at 1.49, 1.35, 1.25 and 1.0 Ga. Zircons recovered from two sandstone levels in the Arroyo del Soldado Group (Yerbal and Cerros San Francisco formations) are mostly Archean in age, with maxima at 3.2 and 2.7 Ga. Palaeoproterozoic zircons are also prominent in this unit, with peaks at 2.45 and 2.18, with the latter a typical Transamazonian age. Two samples from the Sierras Bayas Group in Tandilia (Argentina) show different age spectra. Sandstones of the Villa Monica Formation show a unimodal zircon population of Transamazonian age (peak at 2.13 Ga). Sandstones of the Cerro Largo Formation are characterized by a dominant Transamazonian zircon population (peaks at 2.15, 2.0 and 1.79), but also important Archean-lowermost Palaeoproterozoic (3.33, 2.99, 2.7, 2.47 Ga) and Mesoproterozoic peaks (1.55, 1.23 and 1.06). The abundance of Mesoproterozoic detrital zircons is surprising. A proto-Andean, Mesoproterozoic belt is suggested as the source of the Mesoproterozoic detritus. Archean rocks of the RPC crop out only in the Nico Perez Terrane in Uruguay, suggesting that the Nico Perez Terrane was much closer to Tandilia than it is today. The sinistral reactivation of the Sarandi del Yi Shear Zone in the Cambrian, as a result of tangential collision of the Cuchilla Dionisio-Pelotas Terrane, may explain this observations. The absence of Neoproterozoic zircons shows that the studied units were deposited in a stable continental margin opening to the East and South. These Neoproterozoic basins had obviously no contribution whatsoever from Brasiliano-Pan African belts, supporting the idea of Cambrian terrane

    Bovine viral diarrhea (BVD) affects bovine production and reproduction causing significant economic losses all over the world. Two viral species has been recognized: BVDV-1 and BVDV-2, both distributed worldwide. Recently, novel specie of BVDV named HoBi-like pestivirus was discovered. The presence of BVDV was confirmed in 1996 in Uruguay, however, does not exist until today a schedule of compulsory vaccination along the country. Serological studies with samples from all Uruguayan herds were performed during 2000 and 2001 demonstrating that all of them were seropositive to BVDV with a mean prevalence of 69%. In addition, there have been no new studies done since those previously described and it is important to mention that the genetic diversity of BVD has never been described in Uruguay. Nowadays, there is strongly suspect that BVDV is one of the most important causes of reproductive failures in our herds. The aim of this study was to describe for the first time in Uruguay the genetic diversity of BVDV with samples collected from different regions along the country. Serological status of 390 non-vaccinated animals against BVDV with reproductive problems from farms of Rivera, Tacuarembó and Florida departments of Uruguay were studied. All herds were seropositive to BVDV and high proportion of animals were positive (298/390), while 4.1% (16/390) of the animals were positive to Antigen Capture ELISA test and Real Time PCR. Phylogenetic analysis performed with concatenated sequences from the 5'UTR and Npro genomic regions revealed that BVDV-1 and BVDV-2 are infecting our herds, being BVDV-1 the most frequently found. The major subtype was BVDV-1a, followed by BVDV-1i and BVDV-2b. This is the first study that describes the genetic diversity of BVDV in Uruguay and it will contribute to the elaboration of sanitization programs.

  3. Carbonate rocks of Cambrian and Ordovician age in the Lancaster quadrangle, Pennsylvania

    Science.gov (United States)

    Meisler, Harold; Becher, Albert E.

    1968-01-01

    Detailed mapping has shown that the carbonate rocks of Cambrian and Ordovician age in the Lancaster quadrangle, Pennsylvania, can be divided into 14 rock-stratigraphic units. These units are defined primarily by their relative proportions of limestone and dolomite. The oldest units, the Vintage, Kinzers, and Ledger Formations of Cambrian age, and the Conestoga Limestone of Ordovician age are retained in this report. The Zooks Corner Formation, of Cambrian age, a dolomite unit overlying the Ledger Dolomite, is named here for exposures along Conestoga Creek near the village of Zooks Corner. The Conococheague (Cambrian) and Beekmantown (Ordovician) Limestones, as mapped by earlier workers, have been elevated to group rank and subdivided into formations that are correlated with and named for geologic units in Lebanon and Berks Counties, Pa. These formations, from oldest to youngest, are the Buffalo Springs, Snitz Creek, Millbach, and Richland Formations of the Conococheague Group, and the Stonehenge, Bpler, and Ontelaunee Formations of the Beekmantown Group. The Annville and Myerstown Limestones, which are named for lithologically similar units in Dauphin and Lebanon Counties, Pa., overlie the Beekmantown Group in one small area in the quadrangle.

    1991-02-01

    Biofacies that formed on carbonate platform-margin slopes adjacent to an early Paleozoic, low-paleolatitude paleoocean are contained in the Upper Cambrian Swarbrick Formation, Tyby Shale, and Upper Cambrian-lowest Ordovician Hales Limestone of the Hot Creek Range, Nevada, and the Upper Cambrian-lowest Ordovician part of the Shabakty Suite of the Malyi Karatau, southern Kazakhstan. These in-situ limestones formed in platform-margin slope and basin-plain environments. Shoal-water faunal assemblages occur in carbonate-turbidite and debris-flow deposits interbedded with in-situ deeper water assemblages of the submarine-fan facies. Abundant sponge spicules, geographically widespread benthic trilobites, and rare ostracodes occur in some of the in-situ beds. In contrast, the shoal-water platform environments were well oxygenated and contain mainly endemic trilobite assemblages. These biofacies characteristics support an interpretation that Late Cambrian oceans were poorly oxygenated, but not anoxic, below the surface mixing layer and that benthic trilobite faunas were widely distributed in response to the more-or-less continuous deep water, low-oxygen habitats. Elements of the Late Cambrian low-oxygen biofacies are widespread in the Tien Shan structural belt of China and the Soviet Union, in central and eastern China, and along the western margin of early Paleozoic North America. This facies distribution pattern defines the transition from low-paleolatitude, shoal-water carbonate platforms to open oceans which have since been destroyed by pre-Late Ordovician and pre-middle Paleozoic Paleotectonic activity.

    Cambrian and Ordovician shelf, platform, and basin rocks are present in Sonora, Mexico, and southern Arizona and were deposited on the southwestern continental margin of North America (Laurentia). Cambrian and Ordovician rocks in Sonora, Mexico, are mostly exposed in scattered outcrops in the northern half of the state. Their discontinuous nature results from extensive Quaternary and Tertiary surficial cover, from Tertiary and Mesozoic granitic batholiths in western Sonora, and from widespread Tertiary volcanic deposits in the Sierra Madre Occidental in eastern Sonora. Cambrian and Ordovician shelf rocks were deposited as part of the the southern miogeocline on the southwestern continental margin of North America.

  9. U-Pb age constraints for the La Tuna Granite and Montevideo Formation (Paleoproterozoic, Uruguay): Unravelling the structure of the Río de la Plata Craton

    The Río de la Plata Craton is a continental block that crops out in Uruguay, eastern Argentina, southernmost Brazil and Paraguay. It comprises in Uruguay the Piedra Alta, Tandilia and Nico Pérez terranes, separated by the Colonia and the Sarandí del Yí megashears. The La Tuna Granite, which intrudes the Araminda metasandstones in the Tandilia Terrane, was considered Cambrian in age and the intruded sandstones were assigned to the Neoproterozoic Piedras de Afilar Formation. We show that the granite is Paleoproterozoic in age and that the host metasandstones do not belong to the Piedras de Afilar Formation, but to the Paleoproterozoic Montevideo Formation. U-Pb LA ICP-MS of zircon ages for the La Tuna Granite yielded a concordant crystallization age of 2156 ± 26 Ma. Furthermore a metamorphic event at 2010 ± 9 Ma is revealed by Pb stepwise leaching dating of monazites. U-Pb detrital zircon ages of the host Araminda metasandstone yield an upper intercept discordia age of 2152 ± 29 Ma, which marks the intrusion of the La Tuna pluton, and which is in accordance with the zircon U-Pb LA ICP MS constraints. A concordant U-Pb detrital zircon age of 2465 ± 40 Ma provides a maximum depositional age constraint for the metapsammites. Comparing quartz arenites of the Ediacaran Piedras de Afilar Formation with the Araminda metaquartzites, we conclude that they are very similar regarding petrology but they differ in age and metamorphic overprint. Detrital zircons in quartz arenites of the Piedras de Afilar Formation show youngest ages of 1.0 Ga. On the other hand, detrital zircons recovered from the Araminda metasandstones and the age of the intruding granite allow interpreting a depositional age between 2465 and 2150 Ma. Nd model ages show crustal residence times in average more than 200 myr older for the Tandilia Terrane both in Uruguay and Argentina, with a significant Neoarchean component, which is lacking in the Piedra Alta Terrane.

    2015-01-01

    My first contact with the IAEA was in 1989 in Moscow, at ATOMINFORM while attending the International Centre for Scientific and Technical Information (ICSTI) training: INIS Human Resources: On the Job Group Training for Developing INIS Member States. Lectures were given about FIBRE data entry software and searches on INIS CD-ROM. Through the Regional Cooperation Agreement for the Promotion of Nuclear Science and Technology in Latin America and the Caribbean, specifically by the ARCAL X project, modern technologies for access to information were introduced and the creation of INIS Centres was supported. During its execution, from 1985–1992, many countries in the region became members of INIS, including our country, Uruguay. Our involvement in the RLA/0/017 ARCAL XLII Regional Network for Nuclear Information increased after our application for INIS Liaison Officer was submitted by government authorities in Uruguay. This enabled better conditions for the formation of a nuclear Regional Information Network with 15 countries in Latin America

    The morphology and evolution of the continental margin of Uruguay is due to the interaction of an important set of sedimentary processes. The contourite and turbiditic are the most significant processes which are associated with the development of submarine canyons as well as the gravitational mass respect to major landslides. These processes generate erosional and depositional features with a direct impact on different areas of application, which have potential environmental risks (gravitational landslides, earthquakes, tsunamis) and potential economic resources

    There is widespread concern that the Uruguay Round may reduce the welfare of developing countries through its effect on world agricultural prices. Reduced agricultural price distortions among major supplying nations are predicted to increase basic food prices and decrease some important export prices such as those for coffee and cotton.

    Montano J; Gagliardi, S; Montano, M.

    2005-01-01

    Traditionally the use of the water resources in Uruguay was based on the exploitation of surface waters due to the great density of the hydrographic network. The intensive use of the groundwater resources began after 1950, mainly for supplying small towns the country, nowadays this practice covers the 70% of the country. Basically, this evolution was a consequence of the lower cost of the groundwater, its availability and good quality. Since 1980 the use of the groundwater has been intensified even more, mainly with the purpose of satisfying different demands like vegetable plantation irrigation either in the open air or in the entrance of cholera to the country during the 1990 decade trough a program for supplying water to small communities in the frontier area. In addition, it is marked out the use of thermal and flowing aquifers belonging to the Guarani Aquifer System as water suppliers for thermal spas and hotels in a reduced area, eventhough having a great hydric potencial whose exploitation yields one of the major foreing currency entrance because of regional tourism. Moreover, it can be stated that Uruguay do not present an important groundwater weath because of regional tourism. Moreover, it can be stated that Uruguay do not present an important groundwater weath because the 65% of its aquifers are fisurated and the others are pourous with diverse potentiality.

    Full Text Available This paper focuses on the impact of the Uruguay Round (UR implementation on world agriculture using a multi-regional general equilibrium model and the mapping function of the Geographic Information System (GIS. The results of this study show that the Uruguay Round has had a negative impact on world agriculture in the light of total food production and food distribution. For commodities such as grains, while grain production rises in exporting countries, the effect is not sufficient to cover the fall in production in importing countries. In particular, the impact is serious on food security in importing countries of agricultural products. The negative impact is almost concentrated in importing countries, particularly Japan, the European Union (EU and South Korea. As is clearly visible on the maps produced by the GIS function, the real state of world agriculture as well as the results evaluated by this Computable General Equilibrium (CGE model has changed negatively in major importing countries and particularly the Least Developed Countries (LDCs, Sub-Saharan Africa following the Uruguay Round.

    The western cratonic domains in Uruguay are divided into three major units: Piedra Alta Terrane, Valentines Block and Pavas Terrane. Piedra Alta Terrane lacks of evidence of Neo proterozoic oro geneses (deformation, metamorphism or magmatism). Sarandi del Yi - Arroyo Solis Grande shear zone, separates it from Valentines Block. Valentines Block is separated from Pavas Terrane by Cueva del Tigre shear zone. Magmatic rocks with different ages, compositions and emplacements occur all over the Piedra Alta Terrane distributed in three metamorphic belts (Arroyo Grande, San Jose and Montevideo) as well as in the Central Gneissic-Migmatitic Complex. Samples from the gneissic-migmatitic complex, late tectonic granitoids and basic rocks associated to the metamorphic belts were analyzed using Rb/Sr, U/Pb, K/Ar and Sm/Nd methodologies. The age ranges obtained for granitoids and gneissicmigmatitic samples using Rb/Sr whole rock (WR) systematics are 1.7 to 2.5 Ga, showing two intervals: 1.9 to 2.05 Ga (intrusion of late granites) and 2.1 to 2.2 Ga (deformation and metamorphism). K/Ar cooling ages present several ranges: 1.3 to 1.35 Ga (probable local heating of the crust), 1.7 to 1.8 Ga (microgabbro magmatism, data confirmed by the Ar/Ar method) and ages between 2.0 to 2.2 Ga. Rb/Sr (WR) data yielded an isochronic age of 2094 ± 28.3 Ma, Ro = 0.70174 ± 0.00009, MSWD 19.74, interpreted as the time of the metamorphic event recognized for all the Piedra Alta Terrane. TDM Sm/Nd model ages presented a range from 2065 Ma to 2450 Ma. U/Pb systematics yield ages in migmatitic and gneissic rocks from 2.16 Ga to 2.21 Ga, showing metamorphism and deformation phenomena. While the ages of granitoids associated to the San Jose Belt are between 2.06 Ga and 2.08 Ga (Isla Mala) to 2.1 Ga (Granito de Cufre). None of them show metamorphic phenomena. Valentines Block (Preciozzi et al., 1979) comprises granulitic gneisses, granitoids and mafic rocks of different compositions. The geologic complexity

    1990-08-01

    The classic Cambrian-Ordovician ichnostratigraphic paradigm originally developed in Europe is based on the assumption that Cruziana - ichnofossils presumably produced by trilobites - can be used in much the same way as trilobite body fossils have been used in chronostratigraphy. That these ichnofossils can be found in many otherwise unfossiliferous, shallow-marine siliciclastic deposits has made them extremely valuable as correlation tools. The paradigm has been used to date lower Paleozoic units in eastern Canada and Europe. It has also been used as supporting evidence to show close affinities between (1) eastern North America, Wales, and Spain and (2) Spain, northern Africa, and southern Asia. Ichnospecies indicative of the Lower Ordovician (Tremadocian and Arenigian), according to the paradigm, have been recovered from the Lower Cambrian (Atdabanian) Gog Group, near Lake Louise, Alberta, Canada. This discovery indicates that these ichnospecies cannot be used as global Lower Ordovician index fossils.

  8. Modern optics in exceptionally preserved eyes of Early Cambrian arthropods from Australia

    Despite the status of the eye as an ``organ of extreme perfection'', theory suggests that complex eyes can evolve very rapidly. The fossil record has, until now, been inadequate in providing insight into the early evolution of eyes during the initial radiation of many animal groups known as the Cambrian explosion. This is surprising because Cambrian Burgess-Shale-type deposits are replete with exquisitely preserved animals, especially arthropods, that possess eyes. However, with the exception of biomineralized trilobite eyes, virtually nothing is known about the details of their optical design. Here we report exceptionally preserved fossil eyes from the Early Cambrian (~515 million years ago) Emu Bay Shale of South Australia, revealing that some of the earliest arthropods possessed highly advanced compound eyes, each with over 3,000 large ommatidial lenses and a specialized `bright zone'. These are the oldest non-biomineralized eyes known in such detail, with preservation quality exceeding that found in the Burgess Shale and Chengjiang deposits. Non-biomineralized eyes of similar complexity are otherwise unknown until about 85 million years later. The arrangement and size of the lenses indicate that these eyes belonged to an active predator that was capable of seeing in low light. The eyes are more complex than those known from contemporaneous trilobites and are as advanced as those of many living forms. They provide further evidence that the Cambrian explosion involved rapid innovation in fine-scale anatomy as well as gross morphology, and are consistent with the concept that the development of advanced vision helped to drive this great evolutionary event.

  10. Self-regulation of trilobite diversity in Murero (middle Cambrian, Spain) due to compensatory extinction

    Energy Technology Data Exchange (ETDEWEB)

    Lopez-Villalta, J.S.

    2016-07-01

    As species accumulate in a community, competition for available ecospace is expected to prevent the addition of new species and to facilitate species extinction, thus producing a dynamic equilibrium of diversity. This mechanism remains under debate since its empirical support comes mainly from indirect or partial evidence, with very few direct tests at the species level. Here a new method is described to detect the presence of selfregulation feedbacks between species richness and turnover rates. It consists of Monte Carlo simulations which randomize the distribution of species ranges among stratigraphic intervals, providing predictions which allow the detection of genuine self-regulation feedbacks in the real data. Since the simulations include any potential bias due to preservation, sampling, or change in depositional environment, and these biases would also affect the real dataset, they are thus ruled out as explanations for any difference found. This method is applied to one of the best known fossiliferous sequences worldwide, the Rambla de Valdemiedes in Murero (RV1 section, middle Cambrian, Spain), a classic locality that has been studied for more than 150 years and which stands out due to its excellent sampling density, continuous deposition, and homogeneous fossil preservation. The results show that trilobite species richness was self-regulated due to positive feedback with extinction rate, which implies that compensatory extinction regulated this fauna in spite of the on-going Cambrian radiation. The lack of evidence of any origination feedback suggests ecological opportunities were not limiting for new species to colonize this Cambrian community. (Author)

    Cycloneuralians form a rich and diverse element within Cambrian assemblages of exceptionally preserved fossils. Most resemble priapulid worms whereas other Cycloneuralia (Nematoda, Nematomorpha, Kinorhyncha, Loricifera), well known at the present day, have little or no fossil record. First reports of Sirilorica Peel, 2010 from the lower Cambrian Sirius Passet fauna of North Greenland described a tubular lorica covering the abdomen and part of a well developed introvert with a circlet of 6 grasping denticles near the lorica. The introvert is now known to terminate in a narrow mouth tube, while a conical anal field is also developed. Broad muscular bands between the plates in the lorica indicate that it was capable of movement by rhythmic expansion and contraction of the lorica. Sirilorica is regarded as a macrobenthic member of the stem-lineage of the miniaturised, interstitial, present day Loricifera. Like loriciferans, Sirilorica is now known to have grown by moulting. Evidence of the life cycle of Sirilorica is described, including a large post-larval stage and probably an initial larva similar to that of the middle Cambrian fossil Orstenoloricusshergoldii.

    Read, J. Fred; Repetski, John E.

    2012-01-01

    The southern Appalachian part of the Cambrian–Ordovician passive margin succession of the great American carbonate bank extends from the Lower Cambrian to the lower Middle Ordovician, is as much as 3.5 km (2.2 mi) thick, and has long-term subsidence rates exceeding 5 cm (2 in.)/k.y. Subsiding depocenters separated by arches controlled sediment thickness. The succession consists of five supersequences, each of which contains several third-order sequences, and numerous meter-scale parasequences. Siliciclastic-prone supersequence 1 (Lower Cambrian Chilhowee Group fluvial rift clastics grading up into shelf siliciclastics) underlies the passive margin carbonates. Supersequence 2 consists of the Lower Cambrian Shady Dolomite–Rome-Waynesboro Formations. This is a shallowing-upward ramp succession of thinly bedded to nodular lime mudstones up into carbonate mud-mound facies, overlain by lowstand quartzose carbonates, and then a rimmed shelf succession capped by highly cyclic regressive carbonates and red beds (Rome-Waynesboro Formations). Foreslope facies include megabreccias, grainstone, and thin-bedded carbonate turbidites and deep-water rhythmites. Supersequence 3 rests on a major unconformity and consists of a Middle Cambrian differentiated rimmed shelf carbonate with highly cyclic facies (Elbrook Formation) extending in from the rim and passing via an oolitic ramp into a large structurally controlled intrashelf basin (Conasauga Shale). Filling of the intrashelf basin caused widespread deposition of thin quartz sandstones at the base of supersequence 4, overlain by widespread cyclic carbonates (Upper Cambrian lower Knox Group Copper Ridge Dolomite in the south; Conococheague Formation in the north). Supersequence 5 (Lower Ordovician upper Knox in the south; Lower to Middle Ordovician Beekmantown Group in the north) has a basal quartz sandstone-prone unit, overlain by cyclic ramp carbonates, that grade downdip into thrombolite grainstone and then storm

    Antibodies to Toxoplasma gondii were measured before and after pregnancy in a 1:64 dilution of sera with the direct agglutination test in 1613 ewes from 18 farms in eight different counties of Uruguay from 1992 to 1994. The overall seroprevalence increased from 28.7% before mating to 38.5% after lambing in 2.5 years and thus the incidence was 9.8%. Losses due to toxoplasmosis during pregnancy were estimated to be 1.4-3.9% of the total number of ewes investigated, amounting to approximately US$1.4-4.7 million for the whole country.

    Conglomeradic and sandstones lithofacies corresponding to fluvial and alluvial environments were recognized. These sediments partially belong to the quaternary Mataojos Formation. A discordant contact with the upper pelitic deposits identified with the Sopas Formation was detected. This paper deals with sedimentological and stratigraphical considerations in order to explain the sedimentary processes during the genesis of these stratigraphic sections as well as to begin a lithostratigraphical discussion about the operability of those units. In turn, chronologic and paleoenvironment comments are provided taken into account vertebrates fossils and tools to perform chronocorrelation with southern sedimentological units of Uruguay [es

  7. Evolution of oceanic molybdenum and uranium reservoir size around the Ediacaran-Cambrian transition: Evidence from western Zhejiang, South China

    The "Cambrian explosion" is one of the most fascinating episodes of diversification in the history of life; however, its relationship to the oxygenation of the oceans and atmosphere around the Ediacaran-Cambrian transition is not fully understood. Marine inventories of redox-sensitive trace elements reflect the relative balance of oxidative weathering on land and deposition in anoxic water masses, and can be used to explore the evolution of oceanic and atmospheric redox conditions. For this study, we conducted a series of geochemical analyses on the upper Lantian, Piyuancun, and Hetang formations in the Chunye-1 well, part of the lower Yangtze Block in western Zhejiang. Iron speciation results indicate that the entire studied interval was deposited under anoxic conditions, with three intervals of persistent euxinia occurring in the uppermost Lantian Fm., the lower Hetang Formation (Fm.), and the upper Hetang Fm. Molybdenum (Mo) and uranium (U) contents and Mo/TOC and U/TOC ratios from the anoxic/euxinic intervals of the Chunye-1 well, combined with published data from the sections in the middle and upper Yangtze Block, suggest that the oceanic Mo reservoir declined consistently from the Ediacaran to Cambrian Stage 3, while the size of the oceanic U reservoir remained relatively constant. Both metals were depleted in the ocean in lower Cambrian Stage 4, before increasing markedly at the end of Stage 4. The lack of an apparent increase in the size of the marine Mo and U reservoir from the upper Ediacaran to Cambrian Stage 3 suggests that oxic water masses did not expand until Cambrian Stage 4. The increase in marine Mo and U availability in the upper Hetang Fm. may have been due to the expansion of oxic water masses in the oceans, associated with oxygenation of the atmosphere during Cambrian Stage 4. This expansion of oxic waters in the global ocean postdates the main phase of Cambrian diversification, suggesting that pervasive oxygenation of the ocean on a large

    Volcanic activities related to the opening of a Cambrian rift in Morocco were widespread from the Fortunian to the Cambrian Epoch 3. Numerous data are available from northwestern volcanic sites, particularly in the western High Atlas, but they are scarce from the southeastern sites. New data are documented here from the volcanic formations exposed in the Jbel Tazoult n'Ouzina of the Tafilalt Province, eastern Anti-Atlas and dated to Cambrian Epoch 2-3. The Cambrian volcanic activities recorded in the High Atlas, Anti-Atlas, and Coastal Meseta are synthesized to refine their stratigraphic setting and to characterize their magmatic affinities and fingerprints. Six volcanic pulses are determined as tholeiitic, transitional, and alkaline suites. The tholeiitic and transitional magmas originated from primitive mantle and E-MORB-type sources with a spinel- and garnet-bearing lherzolite composition. Some of them were modified by assimilation-fractional crystallisation processes during crust-mantle interactions. The alkaline magmas fit with an OIB-type and a garnet-bearing lherzolite source. The palaeogeographic distribution of the magmatic suites was controlled by the lithospheric thinning of the Cambrian Atlas Rift and lithospheric constraints of the Pan-African metacraton and West African craton.

Among the smokers, 1.3% using EC daily and 1.9% using EC weekly. Conclusions Taste is a very important factor for Uruguayan smokers. Almost all young smokers have tried menthol cigarettes. ECs use is also on the rise, mainly among young peopleand people with higher education. There is a need for monitoring flavored cigarettes and EC consumptionto defining new regulations for them.

  11. Paleomagnetism of Early Cambrian Itabaiana mafic dikes (NE Brazil) and the final assembly of Gondwana

    Paleomagnetic analysis on 15 early Cambrian mafic dikes from Itabaiana (Paraíba State) yielded a southern (northwestern) direction with steep upward (downward) inclination ( Dm = 167.5°, Im = - 63.7°, α95 = 7.3°). AF and Thermal demagnetization, thermomagnetic curves, and hysteresis results suggest that this component is dominantly carried by fine-grained SD magnetite. The high stability of this component and positive baked contact tests on three dikes indicate it represents a primary thermoremanent magnetization. Ar-Ar analysis on whole-rock samples from two sites provides a strong constraint on the age of the Itabaiana paleomagnetic pole (134.6° E, 34.9° S; A95 = 7.3, K = 28) defined by plateau ages of 525 ± 5 and 526 ± 4 Ma. This pole completely satisfies six out of the seven quality criteria proposed by Van der Voo [R. Van der Voo, The reliability of paleomagnetic data, Tectonophysics 184 (1990) 1-9.] and permits a tight constraint on the Early Cambrian sector of the Gondwana apparent polar wander path. Paleogeographic reconstructions consistent with the available paleomagnetic and geological record show that Gondwana was sutured along three major orogenies, the Mozambique (Brasilano/Pan-African) Orogeny (800-650 Ma), the Kuunga Orogeny (570-530 Ma) and the Pampean-Araguaia Orogeny (540-520 Ma). We suggest that after rifting away from Laurentia at the end of the Neoproterozoic, opening the Iapetus ocean, the Amazonian craton and minor adjoining blocks, such as Rio Apa and Pampia, collided with the proto-Gondwana by Cambrian times at ca. 530-520 Ma. Unless for small adjustments, Gondwana was completely formed by 525 Ma whose paleogeography is defined by the Itabaiana pole.

    Lower Cambrian successions described from Scandinavia are reviewed and subjected to sequence stratigraphical analysis; comparisons are also made with successions described from northeast Poland, Estonia, Latvia and Lithuania. The treated stratigraphic interval is bounded upwards by a regional unconformity ascribed to the Hawke Bay Event. The East European regional stage classification, comprising the Rovnian, Lontovan, Dominopolian, Ljubomlian, Vergalian, Rausvian and Kibartian, is adopted for the Lower Cambrian of Scandinavia. These units are approximately equivalent to the Terreneuvian and Cambrian provisional series 2. The Rovnian and Lontovan stages are pre-trilobitic. The Dominopolian and 'Ljubomlian' stages encompass the ' Rusophycus' and Schmidtiellus mickwitzi zones; whether the former zone is of pre-trilobitic age is uncertain but possible. The 'Ljubomlian' is treated informally because the definition adopted in this paper does not correspond to the original concept of the stage. The Vergalian and Rausvian are for the time being classified as one combined stage. The lower main part of the Vergalian-Rausvian corresponds to the new informal Holmia kjerulfi- 'Ornamentaspis' linnarssoni zone, whereas the upper part is separated as the new informal Comluella?-Ellipsocephalus lunatus zone. This zone also includes the Kibartian Stage. Volborthella and poorly known olenellid trilobites range into the Kibartian and the stage is considered of Early Cambrian age. The Holmia inusitata Zone is abandoned; it is contemporaneous with the traditional ' O.' linnarssoni Zone. The autochthonous strata underlying the Hawke Bay unconformity in the Laisvall sector, Swedish Lapland, are assigned to the Laisberg and Grammajukku formations and it is proposed to abandon the Laisvall and Såvvare formations. The Laisberg Fm can locally be divided into the Ackerselet, Saivatj, Maiva, Kautsky Ore, Tjalek, Nadok Ore and Assjatj members. The Vakkejokk Breccia near Luopakte is likely

    Rocks with boninitic affinities have been recognised in a number of “ophiolites”, including the Cambrian Heathcote and Mt Wellington Greenstone Belts of Victoria. Boninites and high-Mg andesites from the Heathcote Greenstone Belt show a restricted range of initial ɛ Nd values of between +3.3 to +5.8. Extremely refractory boninites from the Mt Wellington Greenstone Belt have ɛ Nd ranging from +1.3 to -9. Ti/Zr is positively correlated with Sm/Nd with the Heathcote lavas generally possessing greater depletion of Ti and enrichment of Zr relative to the middle and heavy REE with increasing LREE/HREE. These data are consistent with the generation of boninites by partial melting of refractory peridotite following invasion by LREE- and Zr-enriched, low ɛ Nd fluids. Tholeiites overlying the boninites in both greenstone belts have flat REE patterns and ɛ Nd˜+5, lower than that anticipated for lavas derived from depleted MORB source reservoirs in the Cambrian, suggesting that their source was also contaminated by a LREE-enriched, low ɛ Nd component similar to that involved in the generation of the Howqua boninites. The added components have characteristics compatible with their derivation from subducted altered oceanic crust and/or from wet subducted sediments. The identification of boninites and other low-Ti lavas in the Victorian greenstone belts is strong evidence for island arc development in southeastern Australia during the Lower Cambrian and provides further support for a subduction-related origin for many ophiolites.

  14. Cambrian rivers and floodplains: the significance of microbial cementation, groundwater and aeolian sediment transport

    Rivers that existed before land plants colonized the Earth are commonly considered to be unaffected by microbial activity on their floodplains, because the limited cementation produced by microbial activity is insufficient to stabilize the river banks. Although this assumption is likely correct, such emphasis on channel dynamics ignores the potential role of floodplain dynamics as an integral component of the river system. Detailed analysis of cores from the Cambrian Mount Simon Sandstone, Illinois, suggests that a significant proportion of the terrestrial sequence is composed of flat-bedded `crinkly' structures that provide evidence of cementation by soil crusts and microbial biofilms, and that promoted the adhesion of sediment to sticky surfaces. Wind ripples and local desert pavements were abundant. These findings highlight that sediment deposition on Cambrian floodplains was often dominated by wind in locations where the ground water table reached the surface, and was thus likely independent of sediment transport within the river channel. Erosion by wind would thus have been hindered by surface cementation and the formation of desert pavements. Such ground water control on deposition, and resistance to erosion by floodplain surface hardening, appear to have been the primary controls on Cambrian floodplain topography. Because floodplain topography poses a key control on channel and floodplain flow, these processes may have affected patterns of erosion and deposition, as well as reach-scale dynamics such as channel avulsions. The autonomous operation of wind-and-groundwater controlled floodplains makes pre-vegetated river systems more sensitive to climatic conditions such as precipitation and evaporation, and strikingly different from those that occurred after the development of land plants.

    Rudy Lerosey-Aubril

    Full Text Available Despite being internal organs, digestive structures are frequently preserved in Cambrian Lagerstätten. However, the reasons for their fossilisation and their biological implications remain to be thoroughly explored. This is particularly true with arthropods--typically the most diverse fossilised organisms in Cambrian ecosystems--where digestive structures represent an as-yet underexploited alternative to appendage morphology for inferences on their biology. Here we describe the phosphatised digestive structures of three trilobite species from the Cambrian Weeks Formation Lagerstätte (Utah. Their exquisite, three-dimensional preservation reveals unique details on trilobite internal anatomy, such as the position of the mouth and the absence of a differentiated crop. In addition, the presence of paired pygidial organs of an unknown function is reported for the first time. This exceptional material enables exploration of the relationships between gut phosphatisation and the biology of organisms. Indeed, soft-tissue preservation is unusual in these fossils as it is restricted to the digestive structures, which indicates that the gut played a central role in its own phosphatisation. We hypothesize that the gut provided a microenvironment where special conditions could develop and harboured a source of phosphorus. The fact that gut phosphatization has almost exclusively been observed in arthropods could be explained by their uncommon ability to store ions (including phosphorous in their digestive tissues. However, in some specimens from the Weeks Formation, the phosphatisation extends to the entire digestive system, suggesting that trilobites might have had some biological particularities not observed in modern arthropods. We speculate that one of them might have been an increased capacity for ion storage in the gut tissues, related to the moulting of their heavily-mineralised carapace.

    According to estimates by the UICC 2020 the annual number of new cases cancer worldwide will reach 20 million, of which 14 occur in developing countries, which must address the problem with little human and material resources. This increase, in particular the care burden will weigh in countries development, is the result, among other factors, the transition patterns epidemiological, accompanied by an increase in life expectancy at birth. This determines the prevalence of chronic and degenerative diseases within which highlights the cardiovascular and oncological diseases. In Uruguay, the life expectancy at birth has increased from 45 in 1900-75 to end of the century. In parallel we are witnessing a progressive aging of the population, with an increasing proportion of older age groups. taking population aged 65 or more, it represented 4.5% in 1908 and reached 21.2% in 2000 Similarly, cancer mortality has increased percentage, in 2001 representing 23.8% of total deaths. Depending on age, analyzed the increased risk of developing or dying from cancer in Uruguay and its impact is weighted mortality of seven locations more frequent. For each of these locations the percentage of deaths in the population of 65 or more years is as follows: lung 60.9%, breast 60.3%, prostate 91.4%, colorecto 78.3%, 72.3% stomach, esophagus 70.3%, 72.2% pancreas, averaging 69.4% overall.

    Full Text Available We aimed to estimate for the first time the burden of fungal infections in Uruguay. Data on population characteristics and underlying conditions were extracted from the National Statistics Institute, the World Bank, national registries, and published articles. When no data existed, risk populations were used to estimate frequencies extrapolating from the literature. Population structure (inhabitants: total 3,444,006; 73% adults; 35% women younger than 50 years. Size of populations at risk (total cases per year: HIV infected 12,000; acute myeloid leukemia 126; hematopoietic stem cell transplantation 30; solid organ transplants 134; COPD 272,006; asthma in adults 223,431; cystic fibrosis in adults 48; tuberculosis 613; lung cancer 1400. Annual incidence estimations per 100,000: invasive aspergillosis, 22.4; candidemia, 16.4; Candida peritonitis, 3.7; Pneumocystis jirovecii pneumonia, 1.62; cryptococcosis, 0.75; severe asthma with fungal sensitization, 217; allergic bronchopulmonary aspergillosis, 165; recurrent Candida vaginitis, 6323; oral candidiasis, 74.5; and esophageal candidiasis, 25.7. Although some under and overestimations could have been made, we expect that at least 127,525 people suffer from serious fungal infections each year. Sporothrichosis, histoplasmosis, paracoccidioidomycosis, and dermatophytosis are known to be frequent but no data are available to make accurate estimations. Given the magnitude of the burden of fungal infections in Uruguay, efforts should be made to improve surveillance, strengthen laboratory diagnosis, and warrant access to first line antifungals.

  20. Bio fuels and family farming in Uruguay: A feasible alliance?

    2011-01-01

    The global energy crisis caused by high levels of fossil fuels consumption and the signs of oil depletion explain the search for alternative energy to traditional sources. Progress towards bio-fuels policy is positioned in a central place in Uruguay s political agenda. This context converges with a scenario of expansion of agricultural activity, marked by a dynamism based on the domestic economic environment changes, and major transformations in the productive base. In this context, in order to assess the social impacts resulting from the expansion of crops for energy purposes, this research was carried out. It explores the social impact of bio fuels production in Uruguay taking as a reference the situation of family farm production. It assumes that the demand of land for energy crop production puts pressure on other production systems. Related to this, it is possible to establish a continuum between a view that holds that family farms are marginal to bio fuel production, and an inclusive view which encourages the incorporation of family farmers into national production chains. In this scenario, the paper attempts to provide elements to answer the question about whether this new line of national production generates opportunities or threats to family farming

    Four types of eyes serve the visual neuropils of extant arthropods: compound retinas composed of adjacent facets; a visual surface populated by spaced eyelets; a smooth transparent cuticle providing inwardly directed lens cylinders; and single-lens eyes. The first type is a characteristic of pancrustaceans, the eyes of which comprise lenses arranged as hexagonal or rectilinear arrays, each lens crowning 8-9 photoreceptor neurons. Except for Scutigeromorpha, the second type typifies Myriapoda whose relatively large eyelets surmount numerous photoreceptive rhabdoms stacked together as tiers. Scutigeromorph eyes are facetted, each lens crowning some dozen photoreceptor neurons of a modified apposition-type eye. Extant chelicerate eyes are single-lensed except in xiphosurans, whose lateral eyes comprise a cuticle with a smooth outer surface and an inner one providing regular arrays of lens cylinders. This account discusses whether these disparate eye types speak for or against divergence from one ancestral eye type. Previous considerations of eye evolution, focusing on the eyes of trilobites and on facet proliferation in xiphosurans and myriapods, have proposed that the mode of development of eyes in those taxa is distinct from that of pancrustaceans and is the plesiomorphic condition from which facetted eyes have evolved. But the recent discovery of enormous regularly facetted compound eyes belonging to early Cambrian radiodontans suggests that high-resolution facetted eyes with superior optics may be the ground pattern organization for arthropods, predating the evolution of arthrodization and jointed post-protocerebral appendages. Here we provide evidence that compound eye organization in stem-group euarthropods of the Cambrian can be understood in terms of eye morphologies diverging from this ancestral radiodontan-type ground pattern. We show that in certain Cambrian groups apposition eyes relate to fixed or mobile eyestalks, whereas other groups reveal concomitant

    Unicellular organic-walled microfossils from the Cambrian-Ordovician transition in Estonia (ca. 490-480million years ago) exhibit rare characters reflecting their function as reproductive algal cysts. The studied assemblages record the evolutionary history of phytoplankton in the early Palaeozoic...... alga Acetabularia (Chlorophyta), which possesses an intrinsic lid-forming apparatus used during the organism's reproductive stage. Based on the observations on the fossil material and studies on the Acetabularia lid formation, we propose a model of operculum formation in the galeate plexus micro-organisms...

    The Cambrian-Ordovician transition was the time of several key events in the history of Central Asia. They were the accretion of Mariana-type island arc systems to the Siberian continent, the related large-scale orogeny and intrusions of basaltic and granitic magma and the formation of a huge turbidite basin commensurate with the Bengal Gulf basin in the western part of the Central Asian orogenic belt (CAOB). The structure of the basin, as well as the sources and environments of deposition remain open to discussion. This paper presents new major- and trace-element data on Late-Cambrian-Early Ordovician turbidites from different parts of the Russian Altai and a synthesis of Nd isotope composition and ages of detrital zircons. The turbidites share chemical similarity with material shed from weathered continental arcs. Broad variations of CIA (39-73) and ICV (0.63-1.66) signatures in sandstones suggest origin from diverse sources and absence of significant sorting. Trace elements vary considerably and have generally similar patterns in rocks from different terranes. On the other hand, there are at least two provinces according to Nd isotope composition and age of detrital zircons. Samples from eastern Russian Altai contain only Phanerozoic zircons and have Nd isotope ratios similar to those in Early Cambrian island arcs (εNdt + 4.4… + 5.4; TNd(DM)-2-st = 0.8-0.9 Ga). Samples from central, western, and southern parts of Russian Altai contain Precambrian zircons (some as old as Late Archean) and have a less radiogenic Nd composition (εNdt up to -3.6; TNd(DM)-2-st up to 1.5 Ga). The chemical signatures of Late Cambrian to Early Ordovician turbidites indicate a provenance chemically more mature than the island arc rocks, and the presence of zircons with 510-490 Ma ages disproves their genetic relation with island arcs. The turbidite basin formed simultaneously with peaks of granitic and alkali-basaltic magmatism in the western Central Asian orogen and resulted from

    The interest in correlating terranes at opposite margins of the South Atlantic Ocean reflects a natural curiosity of both researchers who work in the eastern South-America and who study southwestern Africa. On a large scale scenario the geology of this region is characterized by a central portion composed of Neo proterozoic-Cambrian belts (Dom Feliciano, Kaoko, Damara, Gariep, Saldania) having on each side old gneissic-migmatitic terrains on both continents (Luis Alves, Rio de La Plata, Kalahari and Congo). In South America the Neoproterozoic Dom Feliciano Belt (DFB) predominates in the eastern part of the region and is internally organized according to three different crustal segments characterized, from southeast to northwest, by a Granite belt (deformed I-type medium to high calc-alkaline granites and alkaline granitoid rocks; a Schist belt (volcano-sedimentary rocks metamorphosed from greenschist to amphibolite facies and intrusive granitoids), and a Foreland basin (anchimetamorphic sedimentary and volcanic rocks), the latter situated between the Schist belt and the Archean-Paleoproterozoic foreland. Despite discontinuously covered by younger sediments, the NS continuity of these three crustal segments is suggested by similar lithotypes, structural characteristics, ages and isotopic signature, as well as by the gravimetric data. The Major Gercino, Cordilheira, and Sierra Ballena shear zones are part of the major NE-SW lineaments that affect all southern Brazilian and Uruguayan Precambrian terrains. They separate the Dom Feliciano Schist Belt (supracrustal rocks of the Brusque-Porongos and Lavalleja groups), to the West, from the granitoids of the Granite belt, to the East. The shear zones are characterized by a regional NE trend and a resultant oblique direction of movement where ductile-brittle structures predominate. It is here postulated, as discussed later on, that this lineament separates terranes that are geologically, geo chronologically and isotopically

    The present work deals with the radioactivity of the Archeozoic-Cambrian rocks of the Weibei area, Shaanxi (China)). A total of 45 rock samples of Archeozoic-Cambrian strata were investigated. The radionuclides of the samples, in Bq kg -1 , have been measured using Na(I)Tl gamma-ray spectrometer. The concentration of 226 Ra, 232 Th and 40 K in the Archeozoic-Cambrian rock samples range from 12.3 to 55.4, from 2.4 to 98.7 and from 58.6 to 1613.3 Bq kg -1 , respectively. The measured activity concentrations for these radionuclides were compared with the typical world average values. To assess the radiological hazard of the natural radioactivity in the samples, the radium equivalent activity, the external hazard index, internal hazard index and the annual gonadal dose equivalent associated with the radionuclides were calculated and compared with the international recommended values.

  9. Paleomagnetism of a well-dated marine succession in South China: A possible Late Cambrian true polar wander (TPW)

    2018-04-01

    The Cambrian true polar wander (TPW) hypothesis remains controversial largely because of the uncertainties in the quality and/or fidelity of the paleomagnetic data as well as their chronological control. Testing the TPW hypothesis requires high-quality paleomagnetic data of sufficient spatial and temporal resolutions. Here, we present paleomagnetic results of a continuous Cambrian shallow marine succession from South China where available detailed biostratigraphy provides exceptional chronological constraints. Forty-three sites of paleomagnetic samples were collected from this limestone-dominated succession. Stepwise thermal demagnetization generally reveals three-component magnetizations. Low- and intermediate-temperature components can be cleaned by ∼330 °C, and the high-temperature component (HTC) was isolated typically from ∼350 to ∼450 °C. A positive fold test and the presence of reversed polarity in the strata, together with rock magnetic data as well as the scanning electron microscopic (SEM) and transmission electron microscopic (TEM) results, collectively suggest that the HTCs are likely primary. A directional shift of the HTCs occurs between the lower-middle Cambrian and the upper Cambrian strata in the succession and is tentatively interpreted to indicate a ∼57° polar wander from ∼500.5 to 494 Ma. Because the rate of polar wander is too fast to be a tectonic origin, this polar wander is interpreted to represent a Late Cambrian TPW. This TPW appears coeval with the Steptoean positive carbon isotope excursion (SPICE) and the major trilobite mass extinctions, suggesting a potential link between the TPW and the Late Cambrian biotic and climatic changes. Because the proposed TPW event is exceptionally well-dated, it should be testable through examination of other worldwide sections.

  10. Cambrian Evolutionary Radiation: Context, correlation, and chronostratigraphy—Overcoming deficiencies of the first appearance datum (FAD) concept

    Use of the first appearance datum (FAD) of a fossil to define a global chronostratigraphic unit's base can lead to intractable correlation and stability problems. FADs are diachronous—they reflect species' evolutionary history, dispersal, biofacies, preservation, collection, and taxonomy. The Cambrian Evolutionary Radiation is characterised by diachronous FADs, biofacies controls, and provincialism of taxa and ecological communities that confound a stable Lower Cambrian chronostratigraphy. Cambrian series and stage definitions require greater attention to assemblage zone successions and non-biostratigraphic, particularly carbon isotope, correlation techniques such as those that define the Ediacaran System base. A redefined, basal Cambrian Trichophycus pedum Assemblage Zone lies above the highest Ediacaran-type biotas (vendobionts, putative metazoans, and calcareous problematica such as Cloudina) and the basal Asteridium tornatum-Comasphaeridium velvetum Zone (acritarchs). This definition and the likely close correspondence of evolutionary origin and local FAD of T. pedum preserves the Fortune Head, Newfoundland, GSSP of the Cambrian base and allows the presence of sub-Cambrian, branched ichnofossils. The sub-Tommotian-equivalent base of Stage 2 (a suggested "Laolinian Stage") should be defined by the I'/L4/ZHUCE δ13C positive peak, bracketed by the lower ranges of Watsonella crosbyi and Aldanella attleborensis (molluscs) and the Skiagia ornata-Fimbrioglomerella membranacea Zone (acritarchs). The W. crosbyi and A. attleborensis FADs cannot define a Stage 2 base as they are diachronous even in the Newfoundland "type" W. crosbyi Zone. The Series 2 base cannot be based on a species' FAD owing to the provincialism of skeletalised metazoans in the Terreneuvian-Series 2 boundary interval and global heterochrony of the oldest trilobites. A Series 2 and Stage 3 (a suggested "Lenaldanian Series" and "Zhurinskyan Stage," new) GSSP base is proposed at the Siberian lower

    The Cambrian-Ordovician Mount Windsor volcanic belt in northern Australia is host to stratiform lenses of massive ferruginous chert that are spatially associated with volcanogenic massive sulfide occurrences, in particular the Thalanga zinc-lead-copper-silver deposit. The rocks are composed principally of Fe2O3 and SiO2, with very low concentrations of alkalic elements, and lithogenous elements such as Al, Zr, and Ti; they are interpreted as nearly pure chemical sediments. Textural evidence is documented of the integral role of filamentous bacteria (and/or fungi) in depositing iron from hydrothermal fluids, and of the inorganic precipitation of silica-iron-oxyhydroxide gels that subsequently matured to subcrystalline and crystalline silica forms. At least three distinct iron-accumulating microbial forms are distinguished: networks of septate filaments, nonseptate filament networks, and extremely coarse branching filaments that do not reconnect. Values for δ34S in disseminated pyrite are up to 50‰ lighter than those of contemporaneous Cambrian seawater, suggesting postdepositional colonization of some ironstones by sulfur-reducing bacteria. The site not only preserves the textural interplay of biological and inorganic depositional processes in exhalites, but also extends the oldest known instance of microbial mediation in vent-proximal hydrothermal iron precipitation to at least 500 Ma.

    Comparative embryology is integral to uncovering the pattern and process of metazoan phylogeny, but it relies on the assumption that life histories of living taxa are representative of their antecedents. Fossil embryos provide a crucial test of this assumption and, potentially, insight into the evolution of development, but because discoveries so far lack phylogenetic constraint, their significance is moot. Here we describe a collection of embryos from the Middle and Late Cambrian period (500 million years ago) of Hunan, south China, that preserves stages of development from cleavage to the pre-hatching embryo of a direct-developing animal comparable to living Scalidophora (phyla Priapulida, Kinorhyncha, Loricifera). The latest-stage embryos show affinity to the Lower Cambrian embryo Markuelia, whose life-history strategy contrasts both with the primitive condition inferred for metazoan phyla and with many proposed hypotheses of affinity, all of which prescribe indirect development. Phylogenetic tests based on these embryological data suggest a stem Scalidophora affinity. These discoveries corroborate, rather than contradict, the predictions of comparative embryology, providing direct historical support for the view that the life-history strategies of living taxa are representative of their stem lineages.

    Kodymirus vagans Chlupáč and Havlíček in Sb Geol Ved Paleontol 6:7-20, 1965 is redescribed as an aglaspidid-like arthropod bearing a single pair of enlarged raptorial appendages, which are shown to be the second cephalic appendage. A number of early Palaeozoic arthropods, recognized from predominantly Cambrian Konservat-Lagerstätten, are known to have borne single pairs of large raptorial appendages. They are well established for the iconic yet problematic anomalocarids, the common megacheirans, and the ubiquitous bivalved Isoxys. Further taxa, such as fuxianhuiids and Branchiocaris, have been reported to have single pairs of specialized cephalic appendages, i.e., appendages differentiated from a largely homonomous limbs series, members of which act in metachronal motion. The homology of these raptorial appendages across these Cambrian arthropods has often been assumed, despite differences in morphology. Thus, anomalocaridids, for instance, have long multiarticulate "frontal appendages" consisting of many articles bearing an armature of paired serial spines, while megacheirans and Isoxys have short "great appendages" consisting of few articles with well-developed endites or elongate fingers. Homology of these appendages would require them to belong to the same cephalic segment. We argue based on morphological evidence that, to the contrary, the raptorial appendages of some of these taxa can be shown to belong to different cephalic segments and are the result of convergence in life habits. K. vagans is yet another important example for this, representing an instance for this morphology from a marginal marine environment.

Se estiman varios modelos para el período 1986-2005 utilizando dos aproximaciones para medir el salario. Se obtiene una elasticidad de -0,09 entre desempleo y salarios. La elasticidad es mayor para los jóvenes, las mujeres y los menos educados. Los resultados indican que la elasticidad crece ante choques macroeconómicos adversos. Además, al desagregar por ocupación o formalidad e informalidad, los resultados sugieren que un aumento del desempleo produce un aumento de la informalidad y del cuentapropismo que lleva a una caída de los ingresos en estos sectores, que actúan como “amortiguador”.

  13. Abortion in Uruguay and Latin America: The position of citizens

    2012-07-01

    Full Text Available Abortion is illegal in most Latin American countries, although there are some attenuating and exonerating causes in its practice. However, studies performed in countries with liberalizing processes for more than two decades, such as the United States, show the persistence of different attitudes towards abortion, which go from points of view that are pro-life to points of view that are pro-choice. Based on Latinobarómetro 2007, this paper analyzes the attitudinal patterns of individuals towards abortion, with emphasis on its degree of justification according to socio-economic features, faith and religion, as well as the countries’ own characteristics. Ordinary least squares estimates for 18 Latin American countries show that men under 40, agnostic, highly educated and with socioeconomic access are those that justify abortion the most; likewise, Uruguay —particularly its female population— is the country where it is most justified.

    Full Text Available So far Uruguay is the only country in the world in which parties carried out open and simultaneous primary elections in order to select their presidential candidates. The effects of employing primaries on the election results are determined by the particular characteristics of the electorate who voluntarily participate in them. From survey data, we analyze the factors affecting participation in such instances and their effects on the type of presidential candidates tend to be elected. The results show that in primary elections vote citizens more educated, more interested in politics, identified with political parties and with more extreme ideological positions. As a result we observe that through primaries, candidates away from the median voter are more likely to be winners than with DSV system.

They are ubiquitous and bioaccumulative. These substances interfere with estrogens and may cause cancer or a decrease in reproductive capacity in addition to changes in the sex of fish and an affectation of biodiversity. In our country we are still consuming substances that have been prohibited globally for causing these effects. For example, since January 2005 in Europe has banned products with more than 0.1% of nonylphenol polyethoxylated. In Uruguay, it is increasingly used as an industrial cleaning agent (wool washing, tanneries, institutional and domestic cleaning (low foam powdered detergents, cleaners. It has low biodegradability and reaches the waterways, sediments and living beings. We should grasp the seriousness of this matter and use substitutes to prevent these consequences.

    Full Text Available Este artículo analiza la trayectoria de la lucha por la tierra en Bella Unión, una región característica en Uruguay por la producción de caña de azúcar, a través de los movimientos de clase de sus principales protagonistas: los cortadores de caña sindicalizados en la Unión de Trabajadores Azucareros de Artigas (UTAA. El recorrido histórico hace énfasis en dos períodos históricos diferentes: 1961-1973 y 2005-presente. El primero va desde la fundación del sindicato hasta el golpe militar. Se da en un contexto de auge de la lucha de masas en Uruguay en el cual los trabajadores rurales se organizan en la UTAA levantando, entre otras, la bandera de la Reforma Agraria. El segundo período está marcado por la llegada al gobierno nacional del Frente Amplio, una coalición social-demócrata que reactiva la producción de caña de azúcar en Bella Unión. Este cambio supone una oportunidad para las luchas sociales que la UTAA aprovecha con ocupaciones de tierra favoreciendo un proceso de colonización para los trabajadores rurales. Sin embargo el acceso a la tierra genera nuevas contradicciones, y por tanto nuevos desafíos, por los cambios en la forma de subsunción del trabajo al capital.

    As a Medical Geology research issue, an environmental arsenic risk assessment study in the most important sedimentary aquifer in southern Uruguay is presented. The Raigon Aquifer System is the most exploited in Uruguay. It has a surface extent of about 1,800 square kilometres and 10,000 inhabitants in San Jose Department, where it was studied. Agriculture and cattle breeding are the main economic activities and this aquifer is the basic support. The groundwater sampling was done on 37 water samples of PRENADER (Natural Resources Management and Irrigation Development Program) wells. Outcropping sediments of Raigon Formation and the overlying Libertad Formation were also sampled in the Kiyu region. The analyses were performed by inductively coupled plasma-optical emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS). The results showed 80% samples with arsenic levels exceeding the 10 μg/l of WHO as limit for waters, and 11% exceeds the 20 μg/l limit of uruguayan regulation. The median, maximum and minimum water arsenic concentrations determined have been 14.24, 24.19 and 1.44 μg/l, respectively. On the other hand, nine sediment samples of Raigon and Libertad Formations in Kiyu region were analysed and yielded median, maximum and minimum arsenic concentrations of 5.03, 9.82 and 1.18 ppm, respectively. This issue leads to the supposition that the population, as well as industrial and agricultural activities, are consuming water with arsenic concentrations over the national and international maximum recommended limit.

    Estimation of petrophysical properties of the rock formations played decisive role in all the processes of petroleum exploration. The Cambrian sequence is well established as reservoir rocks in the various parts of the world from where petroleum is being tapped. The Cambrian sequence has been encountered in the Potwar area and limited petroleum is being produced from the Adhi Oil Field. The Khewra Sandstone of the Cambrian sequence is outcropped in the Khewra Gorge, Salt Range Pakistan below an unconformity qf the Tobra Formation. For the assessment of porosity and reservoir characterization Helium Porosimeter has been used, six samples Qf the upper horizon were collected from various locations of the Khewra Gorge and the Khewra Choha Sadden Shah road side section; cores were prepared from these samples according to the instrument standard. The results of this study revealed that the upper horizon Qf the Khewra Sandstone Formation has good porosity ranging from 18.76% to 21.07%, porosity varied in different parts of the formation. These results are in good agreement with the internationally reported values for petroleum reservoir of the Cambrian sandstone. (author)

  2. Decoupling of body-plan diversification and ecological structuring during the Ediacaran-Cambrian transition: evolutionary and geobiological feedbacks.

    2014-04-07

    The rapid appearance of bilaterian clades at the beginning of the Phanerozoic is one of the most intriguing topics in macroevolution. However, the complex feedbacks between diversification and ecological interactions are still poorly understood. Here, we show that a systematic and comprehensive analysis of the trace-fossil record of the Ediacaran-Cambrian transition indicates that body-plan diversification and ecological structuring were decoupled. The appearance of a wide repertoire of behavioural strategies and body plans occurred by the Fortunian. However, a major shift in benthic ecological structure, recording the establishment of a suspension-feeder infauna, increased complexity of the trophic web, and coupling of benthos and plankton took place during Cambrian Stage 2. Both phases were accompanied by different styles of ecosystem engineering, but only the second one resulted in the establishment of the Phanerozoic-style ecology. In turn, the suspension-feeding infauna may have been the ecological drivers of a further diversification of deposit-feeding strategies by Cambrian Stage 3, favouring an ecological spillover scenario. Trace-fossil information strongly supports the Cambrian explosion, but allows for a short time of phylogenetic fuse during the terminal Ediacaran-Fortunian.

    Markuelia is a vermiform, annulated introvertan animal known as embryonic fossils from the Lower Cambrian to Lower Ordovician. Analysis of an expanded and revised dataset for Introverta shows that the precise position of Markuelia within this clade is dependent on the taxa included. As a result, Markuelia is assigned to the scalidophoran total group to reflect uncertainty as to whether it is a stem-scalidophoran or a stem-priapulid. The taxonomy of the genus is revised to provide an improved taxonomic framework for material assigned to Markuelia. Five species are recognized: M. secunda Val'kov, M. hunanensis Dong and Donoghue, M. lauriei Haug et al., M. spinulifera sp. nov. and M. waloszeki sp. nov. Finally, the preservation of Markuelia is evaluated in the light of both the taphonomy of the fossil embryos themselves and the experimental taphonomy of the priapulid Priapulus caudatus, which has been proposed as both a close relative and an anatomical analogue of Markuelia. ??

  9. Why did life develop on the surface of the Earth in the Cambrian?

    Directory of Open Access Journals (Sweden)

    Carlo Doglioni

    2016-11-01

    Full Text Available Life was limited for most of Earth's history, remaining at a primitive stage and mostly marine until about 0.55 Ga. In the Paleozoic, life eventually exploded and colonized the continental realm. Why had there been such a long period of delayed evolution of life? Early life was dominated by Archaea and Bacteria, which can survive ionizing radiation better than other organisms. The magnetic field preserves the atmosphere, which is the main shield of UV radiation. We explore the hypothesis that the Cambrian explosion of life could have been enabled by the increase of the magnetic field dipole intensity due to the solidification of the inner core, caused by the cooling of the Earth, and the concomitant decrease with time of the high-energy solar flux since the birth of the solar system. Therefore, the two phenomena could be responsible for the growth and thickening of the atmosphere and the development of land surface life.

Here we report high-precision uranium isotopic data in marine carbonates deposited during the Late Cambrian 'SPICE' event, at ca. 499 Ma, documenting a well-defined -0.18‰ negative δ238U excursion that occurs at the onset of the SPICE event's positive δ13C and δ34S excursions, but peaks (and tails off......) before them. Dynamic modelling shows that the different response of the U reservoir cannot be attributed solely to differences in residence times or reservoir sizes - suggesting that two chemically distinct ocean states occurred within the SPICE event. The first ocean stage involved a global expansion...... depletion in the oceans (Gill et al., 2011). We discuss scenarios for how an interval of elevated pyrite and organic carbon burial could have been sustained without widespread euxinia in the water column (both non-sulfidic anoxia and/or a more oxygenated ocean state are possibilities). Either way, the SPICE...

    A biostratigraphic analysis based on trilobites of the main Cambrian outcrops from Sonora, Mexico is performed. The data are based on a combination of field work and published sources, including four previously studied locations from northern and eastern Sonora (Caborca, Cananea, Mazatán, and Arivechi) as well as a new location in the central part of the state of Sonora (San José de Gracia). Chronostratigraphic positions are assigned to the Cambrian outcrops according to Peng et al., 2012 and Cohen et al., 2017. In the Caborca area, the Puerto Blanco, Proveedora, Buelna, Cerro Prieto, Arrojos and El Tren formations comprise a wide range of biozones, which starts from the Fritzaspis Zone until the Glossopleura walcotti Zone (Begadean-Lincolnian Series, global Stage 3-Stage 5, Series 2-Series 3). The Bolsa Quartzite and the Abrigo Limestone exposed in Cananea area are assigned to the Cedaria/Cedarina dakotaensis Zone until the Crepicephalus Zone (Lincolnian Series-Marjuman Stage, global Series 3-Guzhangian). In the San José de Gracia area, The Proveedora, Buelna, Cerro Prieto and El Gavilán formations range from the ?Bristolia mohavensis or ?Bristolia insolens zones until the upper part of Mexicella mexicana Zone, Albertella highlandensis Subzone (Series 2-Series 3, Stage 4-Stage 5). In the Arivechi area, the La Sata, El Mogallón, La Huerta and the Milpillas formations range from Poliella denticulata Zone to the Elvinia Zone (Lincolnian-Millardan, Delamaran-Steptoean, global Series 3-Furongian, Stage 5-Paibian). Paleozoic marine fauna distribution in northwest Mexico and the southwest United States of America, suggest that during this time an extensive faunal province existed, containing a great variety of marine invertebrates with notorious intraspecific affinity. The biotic association includes poriferans, archaeocyathids, brachiopods, mollusks, arthropods and echinoderms as predominant elements.

  13. A new stalked filter-feeder from the middle Cambrian Burgess Shale, British Columbia, Canada.

    Lorna J O'Brien

    Full Text Available Burgess Shale-type deposits provide invaluable insights into the early evolution of body plans and the ecological structure of Cambrian communities, but a number of species, continue to defy phylogenetic interpretations. Here we extend this list to include a new soft-bodied animal, Siphusauctum gregarium n. gen. and n. sp., from the Tulip Beds (Campsite Cliff Shale Member, Burgess Shale Formation of Mount Stephen (Yoho National Park, British Columbia. With 1,133 specimens collected, S. gregarium is clearly the most abundant animal from this locality.This stalked animal (reaching at least 20 cm in length, has a large ovoid calyx connected to a narrow bilayered stem and a small flattened or bulb-like holdfast. The calyx is enclosed by a flexible sheath with six small openings at the base, and a central terminal anus near the top encircled by indistinct openings. A prominent organ, represented by six radially symmetrical segments with comb-like elements, surrounds an internal body cavity with a large stomach, conical median gut and straight intestine. Siphusauctum gregarium was probably an active filter-feeder, with water passing through the calyx openings, capturing food particles with its comb-like elements. It often occurs in large assemblages on single bedding planes suggesting a gregarious lifestyle, with the animal living in high tier clusters. These were probably buried en masse more or less in-situ by rapid mud flow events.Siphusauctum gregarium resembles Dinomischus, another Cambrian enigmatic stalked animal. Principal points of comparison include a long stem with a calyx containing a visceral mass and bract-like elements, and a similar lifestyle albeit occupying different tiering levels. The presence in both animals of a digestive tract with a potential stomach and anus suggest a grade of organization within bilaterians, but relationships with extant phyla are not straightforward. Thus, the broader affinities of S. gregarium remain

    Full Text Available This work attempts to describe the characteristics of the system of building houses by Mutual Assistance Cooperatives, which was introduced in Uruguay in 1968. Its advantages are analyzed with respect to other systems in countries with a capitalist economy, dependent in economic and urban aspects on adapting to the needs of those it is designed for and, in particular, with reference to the profound social and community meaning contained in these experiments. This aspect, which reaffirms values of solidarity deeply-rooted in the sectors of society organized into Cooperatives, subsequently leads the groups to also face colectively other social problems they come up against, which arise from the conditions of under-development and dependence pertaining to Latin American countries: in short, the substantive feature of this type of experience, more than its unquestionable validity, is rather the idea of housing cooperativism as a solution to the habitation problem.El presente trabajo procura describir las características del sistema de construcción de viviendas por Cooperativas de Ayuda Mutua, implantado en el Uruguay, en 1968. Se analizan sus ventajas respecto de otros sistemas en países de economía capitalista dependiente en aspectos económicos, urbanísticos, en la adaptación a las necesidades de los destinatarios y, sobre todo, en lo referente al profundo sentido social y comunitario que estas experiencias contienen. Este aspecto, que reafirma valores solidarios arraigados en los sectores populares organizados en las Cooperativas, conduce posteriormente a los grupos a encarar, también colectivamente, otros problemas sociales que ellos enfrentan, emergentes de las condiciones de subdesarrollo y dependencia de los países latinoamericanos; éste es, en definitiva, más allá de la indiscutible validez, el cooperativismo de vivienda como solución a la problemática habitacional, el rasgo sustantivo de este tipo de experiencias.

    Full Text Available Background: The Atlantic Forest is globally one of the priority ecoregions for biodiversity conservation. In Argentina, it is represented by the Paranense Forest, which covers a vast area of Misiones Province between the Paraná and Uruguay rivers. The Uruguay River is a global hotspot of freshwater gastropod diversity, here mainly represented by Tateidae (genus Potamolithus and to a lesser extent Chilinidae. The family Chilinidae (Gastropoda, Hygrophila includes 21 species currently recorded in Argentina, and three species in the Uruguay River. The species of Chilinidae occur in quite different types of habitats, but generally in clean oxygenated water recording variable temperature ranges. Highly oxygenated freshwater environments (waterfalls and rapids are the most vulnerable continental environments. We provide here novel information on three new species of Chilinidae from environments containing waterfalls and rapids in the Uruguay River malacological province of Argentina. Materials and Methods: The specimens were collected in 2010. We analyzed shell, radula, and nervous and reproductive systems, and determined the molecular genetics. The genetic distance was calculated for two mitochondrial markers (cytochrome c oxidase subunit I–COI- and cytochrome b -Cyt b- for these three new species and the species recorded from the Misionerean, Uruguay River and Lower Paraná-Río de la Plata malacological provinces. In addition, the COI data were analyzed phylogenetically by the neighbor-joining and Bayesian inference techniques. Results: The species described here are different in terms of shell, radula and nervous and reproductive systems, mostly based on the sculpture of the penis sheath. Phylogenetic analyses grouped the three new species with those present in the Lower Paraná-Río de la Plata and Uruguay River malacological provinces. Discussion: Phylogenetic analyses confirm the separation between the Uruguay River and the Misionerean

    Since inception in 1986 the National Direction of Nuclear Technology has fulfilled with the assignment known as 'Control of the ionizing radioactivity in its medical and industrial applications'. This strategic task as far as safety, was performed with significant and crucial deficiencies which they even motivated the users to question the reliability of the institution. The deficiencies were mainly as follows: 1) absence of a regulatory frame; 2) insufficient qualification of technical human resources and 3) lack of suitable equipment. From the use for Uruguay of the Model Project and the beginning of a new management of Dinaten (October 2000), a sensible and well-known increase in the quality and efficiency of the regulating function in the country, which we can summarize in the following landmarks: regulatory frame with the use of a basic norm and eight regulating norms according to the main practices that are developed in the country; intensive training of the regulatory body staff; permanent accomplished update of the inventory of sources; beginning of licensing activities; equipment of last generation; regulation of the personal dosimetry services and management of radioactive waste and establishment of a National Program of Radiological Emergencies.

We analyzed data from a Uruguayan household survey conducted in 2006 using propensity score matching methods and controlling for a number of socio-demographic, family, regional, behavioral health, and labor market characteristics. As expected, we found a positive association between heavy drinking and absenteeism, particularly for female employees. Counter to the findings for developed countries, our results revealed a positive relationship between heavy drinking and labor force participation or employment. This result was mostly driven by men and weakened when considering more severe measures of abusive drinking. Possible explanations for these findings are that employment leads to greater alcohol use through an income effect, that the Uruguayan labor market rewards heavy drinking, or that labor market characteristics typical of less developed countries, such as elevated safety risks or job instability, lead to problem drinking. Future research with panel data should explore these possible mechanisms. Copyright (c) 2009 John Wiley & Sons, Ltd.

    Full Text Available The influence of insecticides commonly used for agricultural purposes on beehive depopulation in Uruguay was investigated. Honeycombs, bees, honey and propolis from depopulated hives were analyzed for pesticide residues, whereas from active beehives only honey and propolis were evaluated. A total of 37 samples were analyzed, representing 14,800 beehives. In depopulated beehives only imidacloprid and fipronil were detected and in active beehives endosulfan, coumaphos, cypermethrin, ethion and chlorpyrifos were found. Coumaphos was present in the highest concentrations, around 1,000 µg/kg, in all the propolis samples from active beehives. Regarding depopulated beehives, the mean levels of imidacloprid found in honeycomb (377 µg/kg, Standard Deviation: 118 and propolis (60 µg/kg, Standard Deviation: 57 are higher than those described to produce bee disorientation and fipronil levels detected in bees (150 and 170 µg/kg are toxic per se. The other insecticides found can affect the global fitness of the bees causing weakness and a decrease in their overall productivity. These preliminary results suggest that bees exposed to pesticides or its residues can lead them in different ways to the beehive.

    Full Text Available Este es un estudio comparativo acerca de cómo nueve comunidades inmigrantes y los afrodescendientes fueron conformando la cultura de Uruguay, un pequeño país en América del Sur. La imagen más común de este país, tanto a nivel nacional como internacional, es la de una sociedad homogénea y europeizada, construida sobre la base de inmigrantes provenientes de España e Italia, con una escasa población afro y sin nativos. Este panorama es cierto sólo a medias ya que también han sido fundamentales las contribuciones de inmigrantes provenientes de Asia, Rusia, otros países europeos y de esclavos africanos y sus descendientes libres. En particular analizaré cómo las personas de ascendencia africana, vascos, italianos, suizos, rusos, armenios, libaneses, judíos, musulmanes y peruanos, han contribuido en la construcción de la nación uruguaya. Este artículo presenta las conclusiones más relevantes de una investigación basada en casi un centenar de entrevistas en profundidad con integrantes de estas comunidades.

    In Uruguay, breast cancer incidence is 76.41 per 100.000, and death rate is 25.22 per 100.000. Since 1998, there is a National Programme of breast cancer early detection for females over forty years of age. We studied the state of the mammography facilities throughout the country. There are 657.000 female over forty and 51 mammography X-ray equipment. The Programme includes 2 mammography X-ray equipment in mobile units in the capital and 18 in hospitals all around the country. There are taken 120.000 mammographic exams per year, 15.000 of them belong to women who had participated in the Programme. We found that no mammography facility has established Quality Assurance Programmes. Despite the results of this study showed that is suitable the number and age of the mammography X-ray equipment, the lack of Quality Assurance Programmes will produce, in a short time, a negative cost-benefit balance. The consequences will be serious social, human an economical damages. (author)

  3. The Pragmatics of Domestic Violence Discourse in Uruguay

    Full Text Available Domestic violence (DV is a form of gender-based violence and a violation of human rights. As such, it was analyzed from the perspective of feminist theory in the dissertation this article is based on, by analyzing discourse pragmatics. Which are the socially accepted DV discourses in Uruguay? Which coincidences, contradictions, and paradoxes appear when we compare these discourses and those of everyday life? Which codes and subcodes should be modified by the sectors interested in the prevention and eradication of DV? The main hypothesis is that there are different types of opposition between the public discourse of different institutional sectors and that of everyday life. Describing these oppositions and, especially, unveiling the pragmatic paradoxes will enable us to develop a different type of discourse for the prevention and eradication of DV. As I am both a researcher and an activist on the topic, my epistemological choice was the autoethnography. This article provides some final reflections, included in the dissertation, on how the feminist movement needs to succeed in persuading decision makers and the mass media, and in building solid alliances to establish an information and monitoring system; the integration of the subject into the educational system; comprehensive legislation on gender-based violence; and new ways of communicating with all sectors, so as to create a new ideology on gender relations for the suitable prevention of DV.

  4. Cannabis consumption patterns among frequent consumers in Uruguay.

    In 2013, Uruguay became the first country to fully regulate the cannabis market, which now operates under state control. Cannabis can be legally acquired in three ways: growing it for personal use (self-cultivation), cannabis club membership, and from pharmacies (not yet implemented). Users must be entered into a confidential official registry to gain access. This article presents findings of a Respondent Driven Sample survey of 294 high-frequency cannabis consumers in the Montevideo metropolitan area. Frequent consumers resort to more than one method for acquiring cannabis, with illegal means still predominating after 1 year of the new regulation law. Cannabis users overwhelmingly support the current regulation, but many of them are reluctant to register. Some of the attitudes and behaviors of the high-frequency consumers pose a challenge to the success of the cannabis law. Individuals relying on more than one method of access defy the single access clause, a prerequisite for legal use, while the maximum amount of cannabis individuals can access monthly seems too high even for most frequent consumers, which might promote the emergence of a grey market. Reluctance to register among a significant proportion of high-frequency consumers raises doubts about the law's ability to achieve its stated objectives. Copyright © 2016 Elsevier B.V.

    2011-01-01

    During the growth and development of grain crops there are a series of limiting factors which prevent obtaining yields to full potential. In particular, in summer crops grown in rain fed conditions, water deficiency stands out as one of the main factors affecting yield productivity. In this study crop evapotranspiration (E Tc) was estimated as a way to assess water needs in summer crops and real evapotranspiration (E Tr) of rain fed crops that occurs under field conditions. The study consisted in estimating E Tc and E Tr of soybean G M IV and V I, corn, sorghum and sunflower in two contrasting climatic regions of Uruguay for a period of 24 years (1984/2007) using the model WinISAREG. Water needs varied. The Nina and Nino years stood out with higher and lower values of Etc respectively. Such water needs are linked to cycle duration. Daily Etc was higher in the North and total Etc was higher in the South. The Etr obtained was substantially lower than Etc and with higher variability in most agr o-climatic situations studied. Sunflower and sorghum were the crops that presented the least differences between Etc and E Tr, and soybean and corn showed the greatest differences at both locations

    Full Text Available This paper analyzed how the main economies have used the antidumping measures (AD after the Uruguay round, between 1995 and 2012. Therefore, some techniques were employed in order to reveal the main AD users and the trend, of using this instrument, associated to each one of them. We also tested the hypothesis that countries could converge in terms of the number of AD cases and if spatial effects could be involved in this process. Finally, a criterion was established and a model was estimated in order to identify countries that usually favor the most competitive sectors through AD practice. The results revealed that Brazil was the only heavy AD user that was counter to the general downward trend verified on the AD cases. Meanwhile, China was not only the main target of this mechanism but the cases against this country showed a growth trend also. Furthermore, we found that the number of AD cases opened by traditional and nontraditional users is converging. Finally, both the index and the estimated model have indicated that Turkey and the EU seem to be favoring the most competitive industries through the AD practice.

    The School of Engineering in Montevideo, Uruguay, within the framework of Agreements made with the National Utility, has carried out an assessment of the potential and studies of the feasibility of the use of renewable energy for the generation of electrical power, both at the industrial level and the autonomous level for rural electrification. Original assessment methodologies were developed, including calculation tools which allow, for example, to analyze historical meteorological data, to calculate the available energy in different kinds of energy generators and also to stimulate the operation and design of autonomous systems with established load requirements and service quality. At the micro and mini hydropower assessment, the main role was placed on the census of potential users and the preliminary analysis of the representative places for the different technical solutions adequate to the variety of topographic conditions and load requirements. For power above 1 MW and up to 5 MW, the generating potential was assessed all over the country. If power lower than 1 MW or lower than 100kW (mini and micro) is considered, the information available in maps with contour lines, including in those of a 1:50,000 scale, is not enough to identify the most adequate places. Instead, knowledge of the place is indispensable in these cases. A preliminary plan of several installations was worked out. (Author)

    Full Text Available Uruguay es uno de los países sudamericanos con una proporción significativa de su población viviendo en el exterior. Desde los años setenta, el país ha tenido una emigración neta. Aunque esta tendencia se debilitó a principios de los noventa, recobró fuerza con la llegada de una severa crisis económica en 1999. En este artículo se discuten las características de la migración reciente de uruguayos y se pone en evidencia la relación entre crisis económica y emigración. El volumen del flujo poblacional en 2002 es comparable con las olas de migración que tuvieron lugar en los setenta. Los emigrantes con educación universitaria están sobrerrepresentados en comparación con la población general. Existe una correlación entre el acceso a redes de emigrantes uruguayos en los países de destino y la probabilidad de que un hogar haya tenido un miembro que emigró en 2002.

    In Uruguay the lack of Radiation Protection (RP) laws makes education in medical use of ionizing radiations at University, a decisive factor of changes. The six years experience in teaching technicians, radiologists, interventional cardiologists and anesthetists in curricular lectures, continuing education courses and workshops, show the importance of a close link between educators and occupationally exposed professionals. Regarding training and education in the optimization of the procedures, it is essential that both teacher and student comprehend the exact meaning of ALARA concept. This implies that although the educator is the one who manages the physical basis of RP, the student is who teaches the educator about the procedures. This turns RP education into a dynamic process in which at the same time, both educator and student learn and teach. After the theoretical lectures, it is essential that students show their ability in applying the acquired knowledge in their everyday practice. Last nut not least, in order to fulfill the first RP principle,all medicine students need to be educated in RP and quality image criteria before the get their medical doctor degree. Our experience shows that RP education in diagnostic radiology requires an expert with both medical physics and Image technology knowledge that allow an approach to students work, language and everyday problems. Despite the fact that the main result of the Education Program is the way professionals improve their practice, another consequence was that the Regulatory Authority of the country called the teacher team to coordinate the first RP national course.

    Full Text Available The Oriental Republic of Uruguay is seen by many as a pioneer among Latin American nations to modernize its state and its policy. Since the late nineteenth century to the twentieth, Uruguayan political actors operate significant changes such as the separation of church and state, labor regulation, divorce law, women's vote, etc. Because of this and the progressive modernization, it was called the “Switzerland of the Americas”. Today, it still stands out in this area by regularizing abortion, homoaffective marriage, liberalization and access to marijuana. Moreover, noteworthy that such measures were achieved largely because of governance that the executive enjoys in the midst of this political system. Thus, this work aims to analyze such Uruguayan political system. In short, a political system is understood by the government system, the electoral system and the party system. That said, it will be analyzed in the political scenario of the country, their characteristics, party and election rules, political parties, party dynamics and relations between the powers.

    Full Text Available Resumen En Uruguay, el Instituto Nacional de Colonización (INC es la institución encargada de la adjudicación de tierra por parte del Estado, orientado a la distribución racional de la tierra y su acceso por parte de la población rural más vulnerable. A partir del año 2005, atravesó una reforma que jerarquizó su rol en las políticas de Estado y gestó un nuevo modelo de adjudicación de tierras: las experiencias asociativas. Ese mismo año, el nuevo gobierno impulsó la transversalización de género en el Estado, impulso que anclara en el INC a partir del 2013. Este artículo analiza desde una perspectiva de género la reforma refundacional y la nueva política de tierras, develando la ceguera de género de la reforma y evidenciando desafíos pendientes para la transversalización de género en el diseño de la principal modalidad de adjudicación de tierras públicas.      Abstract In Uruguay, the National Institute of Colonization is the institution resposible for the adjudication of land by the State, aimed at the rational distribution of land and its access by the most vulnerable rural population. Since 2005, the INC went through a reform that prioritized its role in the policies of the State and created a new model of land adjudication: associative experiences of colonization. In that same year, the new government promoted gender mainstreaming in the State, impulse that took roots in the INC from 2013 onwards. This article analyzes from a gender perspective the refounding reform and the new land policy, unveiling the gender blindness of the reform and highlighting pending challenges for gender mainstreaming in the design of the main public land adjudication modality.

    In southeastern Central Morocco, the Bou-Acila volcanic complex is considered of Cambrian age. In spite of low-grade metamorphic effect, initial volcanic texture and mineralogy can be recognized and volcanic rocks are dominated by dolerites and porphyric dolerites. The initial mineralogy is composed of plagioclases, pyroxenes and dark minerals. A secondary mineral assemblage is composed of albite, epidote, chlorite and calcite. According to their immobile elements compositions, the southeastern central Morocco metavolcanites are of within-plate continental tholeiites. This volcanism and those recognized in many other areas in Morocco confirm a Cambrian extensive episode within the Gondwana supercontinent. To cite this article: H. Ouali et al., C. R.

    Full Text Available O presente estudo teve como objetivo verificar a alteração do nível de Burnout em professores por intermédio da intervenção da técnica de grupos operativos. A amostra foi composta por professores de 5ª a 8ª série de uma escola particular de Porto Alegre, subdividindo-se em dois grupos, o de controle e o experimental, com 12 professores em cada grupo. Para medir a Síndrome de Burnout foi utilizado o MBI (Maslach Burnout Inventory. Após a primeira aplicação do teste em todos os professores, realizaram-se 9 encontros sob a técnica de grupos operativos com o grupo experimental e posteriormente, todos responderam novamente ao teste. Os resultados demonstraram aumento do nível de Burnout, bem como nas suas dimensões: esgotamento emocional, realização profissional e despersonalização para o grupo experimental. Na análise da intervenção constatou-se a importância tanto da sensibilização profissional do trabalho docente como do apoio social entre os professores como estratégias para a prevenção e o enfrentamento da Síndrome de Burnout.

    Full Text Available Populations of Caiman latirostris are known to occur in Uruguay but their geographic distribution remains uncertain. This work presents anupdate of the species distribution and conservation status in Uruguay. Surveys conducted by the authors confirmed the presence of this species in the previously known distribution range of northwestern Uruguay, where it seems to be widespread and relatively abundant in contrast to earlier reports. We report new localities for C. latirostris, most relevant being those of the Cebollatí and Tacuarí Rivers, and the Pelotas, India Muerta and San Miguel stream basins, which significantly expand its distribution through important wetlands in the eastern part of the country. The overall distribution is coincident with different landscape types, where lagoons, artificial impoundments, livestock waterholes, rivers, streams, creeks and marshes are inhabited by caiman. Illegal non-commercial hunting was detected all over the country.

    Full Text Available The older and deeper hydrocarbon accumulations receive increasing attention across the world, providing more technical and commercial challenges to hydrocarbon exploration. We present a study of an asymmetrical, N-S striking intracratonic sag which developed across the Sichuan basin, south China, from Late Ediacaran to Early Cambrian times. The Mianyang-Changning intracratonic sag is ~50 km wide, with its steepest part in the basin center. In particular the eastern margin shows its greatest steepness. Five episodes in the evolutions of the sag can be recognized. It begins in the Late Ediacaran with an uplift and erosion correlated to Tongwan movement. Initial extension occurred during the Early Cambrian Maidiping period, when more strata of the Maidiping Formation were deposited across the sag. Subsequently, maximum extension occurred during the Early Cambrian Qiongzhusi period that resulted in 450–1700 m thick Maidiping-Canglangpu Formations being deposited in the sag. Then, the sag disappeared at the Longwangmiao period, as it was infilled by the sediments. The intracratonic sag has significant influence on the development of high-quality reservoirs in the Dengying and Longwangmiao Formations and source-rock of the Niutitang Formation. It thus indicates that a high probability for oil/gas accumulation exists along the intracratonic sag, across the central Sichuan basin.

    The Precambrian-Cambrian transition is one of the critical time intervals in Earth history. Profound geotectonic, climatic and biological changes occur during the late Neoproterozoic and its transition into the early Cambrian. This study has researched on paired carbonate and organic carbon isotope determinations from Nanjiang, Sichuan Province of the Yangtze Platform, and provided a preliminary geochemical explanation for environmental variations and bio-events observed on the northern Yangtze Platform during the Precambrian-Cambrian transitional interval and their causal relationship. Organic carbon isotopic compositions on sediments vary from -35.8 to -30.1‰ at Nanjiang section; carbonate carbon isotopic compositions change between -3.5 and +0.5‰.

    Colonization of the infaunal ecospace by burrowing bilaterians is one of the most important behavioral innovations during the Ediacaran-Cambrian transition. The establishment of vertical burrows by suspension feeders in high-energy nearshore settings during Cambrian Age 2 is reflected by the appearance of the Skolithos Ichnofacies. For the first time, unquestionable vertical burrows typical of the Skolithos Ichnofacies, such as Skolithos linearis, Diplocraterion parallelum and Arenicolites isp., are recorded from nearshore siliciclastic deposits of the Raizama Formation, southeastern Amazon Craton, Brazil. Integration of ichnologic and sedimentologic datasets suggests that these trace fossils record colonization of high-energy and well-oxygenated nearshore sandy environments. Chronostratigraphically, the presence of these vertical burrows indicates an age not older than early Cambrian for the Raizama Formation, which traditionally has been regarded as Ediacaran. Therefore, the Raizama ichnofauna illustrates the advent of modern Phanerozoic ecology marked by the Agronomic Revolution. The discovery of the Skolithos Ichnofacies in these shallow-marine strata suggests possible connections between some central Western Gondwana basins.

    Precision geochronologic dating and field mapping in the Anti-Atlas Mountains of Morocco document a Neoproterozoic Pan African orogenic cycle consisting of three distinct orogenic events: Iriri-Tichibanine orogeny (760-700 Ma), Bou Azzer orogeny (680-640 Ma) and the WACadomian orogeny (620 Ma to either 555 or 544 Ma). The Iriri-Tichibanine and Bou Azzer orogenies involved northward directed subduction beneath island arc volcanic terranes. These orogenic events generated calc-alkaline magmatism and supra-subduction zone ophiolites exposed in the Bou Azzer and Siroua erosional inliers. The WACadomian orogeny involved subduction and collision of the Cadomia arc complex with the West African Craton and generation of clastic sedimentary basins. The termination of the WACadomian orogeny has been the subject of debate as calc-alkaline to high K magmatism and folding continued to 544 Ma: Was 620-544 Ma calc-alkaline to high K magmatism and clastic basin development due to a) continental rift basin tectonics or b) southward directed subduction and collisional tectonics with associated back arc basin tectonism? We present field and geochemical data supporting the continuation of subduction-collisional tectonics to the Ediacaran-Cambrian boundary 544 Ma. Field mapping in the Central Anti-Atlas (Agadir Melloul) clearly documents an angular unconformity between Ouarzazate Group and Adoudounian limestones (N 30°31'28.91", W07°48'29.12"). Volcaniclastic rocks of Ouarzazate Group (615-545 Ma) are clearly folded and unconformably overlain by Adoudou Formation (541-529 Ma) limestones to the north. Geochemical discrimination diagrams on Latest Neoproterozoic calc-alkaline to high K igneous rocks throughout the Anti-Atlas plot in subduction and collisional arc magma domains. Back arc basin tectonism is likely responsible for localized extensional basins but continental rift tectonics and passive margin sedimentation did not begin in the Anti-Atlas Mountains until Early

  8. Sedimentary mode and reservoir distribution of the Cambrian carbonate & evaporate paragenesis system in the Sichuan Basin

    Full Text Available The Cambrian carbonate & evaporite paragenesis system in the Sichuan Basin is made up of the Longwangmiao, Gaotai and Xixiangchi Fms. So far, great breakthrough has been made only in the Longwangmiao Fm instead of the latter two, and the Anyue Gasfield was discovered in the center of this basin. In this paper, therefore, the Cambrian carbonate & evaporite paragenesis system in the Sichuan Basin was analyzed in terms of its structural–sedimentary setting, sequence stratigraphic framework, sedimentary facies and the distribution of evaporites by using various geologic, logging and seismic data. Then, the geological model of sedimentary facies was established and the distribution range of favorable reservoirs was predicted. Based on these studies, the following results are obtained. Firstly, the palaeotectonic framework is characterized by the style of “one depression between two uplifts” in the setting of a large SE dipping slope, and the stratigraphic filling is in the structure of “onlapping at the bottom and truncation at the top” which is thin in the west and thick in the east. Secondly, three third-order sequence cycles which, on the whole, become shallow upward are developed from bottom to top, and gypsum-salt rocks are mainly located at the high system tract (HST of third-order sequences and concentrated in the Wanzhou–Yibin sag. Thirdly, the geological model of sedimentary facies is composed of three major sedimentary structural layers from bottom to top, namely the evaporative carbonate ramp, the evaporative diamictic restricted platform and the evaporative restricted platform. The sedimentary environment changes from the open to the closed and the penesaline for a long time, and then back to the open. The distribution of shoals changes from the pattern of “dual banks” in a large area to more scattered shoals and banded shoals, while the evaporative lagoon and tidal flat shrink. Fourthly, the reservoir distribution is

  13. A New "Shield of the Weak": Continued Paternalism of Domestic Violence Services in Uruguay.

    2018-03-01

    Drawing on ethnographic and historical research, this article illuminates the limitations of the Uruguayan domestic violence services system. In spite of how advocates in Uruguay successfully used a human rights platform to secure legislation and services, this system now faces significant critique. Using Iris Marion Young's work on the "logic of masculinist protection" and historical parallels in Uruguay's welfare system, I discuss how a paternalistic approach may be to blame. I highlight how this paternalism contributes to the paternalism that problematically underlies gendered violence-reinforcing rather than addressing oppressive ideologies and structures that impede improving conditions for women.

    Full Text Available São estudados os mecanismos psíquicos que se desenvolvem em agrupamentos humanos e a sua utilização para fins terapêuticos, sendo focalizado o fenômeno da interação como o dinamismo básico dessas reações. O autor compara a forma pela qual encara o grupo com as idéias de Bion, Moreno e Sullivan, encarando a hipótese de que os sentimentos de amor e hostilidade se manifestem em função do bom ou do mau funcionamento dos contactos primários que caracterizam a dependência. O autor comenta resultados que obteve usando o psicodrama, mediante o qual estudou reações emocionais de inveja, ódio, agressividade e amor. O autor analisa as técnicas de Slavson e Pratt baseando-se nos dinamismos inerentes ao grupo e refere os estudos de Beukemkamp para a compreensão do fenômeno transferenciai que, no grupo, tem características próprias. As diferenças entre a terapia de grupo e a individual são apontadas, sendo a contra-transferência considerada como elemento construtivo. Pensa o autor que o aspecto dramático vivenciado pelo grupo ou por um dos seus componentes tem alto valor, pois engloba a verbalização, os componentes emocionais e os componentes posturais. O tono emocional vivenciado pelo grupo é mais intenso e opressivo que o que é despertado na terapêutica individual, o que é explicável pela somação de efeitos provocada pela reação circular. Segundo o autor, a Psicoterapia de Grupo e a Psicoterapia Individual não se opõem, mas se completam.

    Full Text Available RESUMEN: En este artículo se argumenta que el muy bajo desempeño económico de Uruguay durante el siglo XX y en particular desde la década de 1960, que lo aleja progresivamente de la dinámica de la economía mundial aumentando la brecha de subdesarrollo, se explica fundamentalmente por la especialización del país en productos de muy escasa dinámica en el mercado mundial así como de muy bajo dinamismo tecnológico. El ensayo de modelo (neoliberal en lo económico y conservador en lo político resultó un fracaso en términos de mejorar la tasa de crecimiento de largo plazo del país, profundizando su especialización basada en productos primarios. Esto implica además un problema en términos de la capacidad de generación de empleos y de la distribución de ingresos. La reactivación reciente así como algunas medidas adoptadas por el nuevo Gobierno Progresista han resultado exitosas en aumentar los salarios, reducir la informalidad y ordenar la macroeconomía luego de la profunda crisis financiera que explotó en el 2002. Pero la ruptura con el pasado, necesaria para elevar significativamente la tasa de crecimiento sostenible de esta economía, requerirá posiblemente de otras acciones en torno a una estrategia de desarrollo de largo plazo, que ponga sus miras en mejorar la capacidad innovadora de la estructura productiva desarrollando nuevas ramas mediante la integración regional.ABSTRACT: This article shows that Uruguay’s very low long term growth performance, which implies an increasing divergence with respect to the world economy, is explained by specialization and productive problems.

    The sulphate reducing bacteria (S RB) constitute a diverse group of anaerobic prokaryotes that carry out the dissimilarity sulphate reduction of sulphur compounds like sulphate, sulphite, tio sulphate, and sulphide to hydrogen sulphide. Although B SR are anaerobic, some genre tolerate oxygen and some others, at low concentrations, can res pirate Fe+ 3 or oxygen, using hydrogen as electron donor. Several industries, including oil and natural gas processing and transporting plants, have been affected by their metabolic activity and the fundamental cause is the production of H S, corrosive and toxic. It damages the pumping equipment, tanks, and 2 pipes. On the other hand, the generated sulphide affects human health and causes security and environmental problems producing severe economic losses. Given the ecological and economic importance of the S RB this study attempts of its presence in soils of different characteristics from southern Uruguay. Although in the last years its knowledge at molecular level has been increased, there is still lack of information so as to be able to control all the effects produced by its metabolic activity. The objective of our work is to determine the degree of diversity of these bacteria in our soils and to know the bio corrosion potential of them. As a first step we have collected soil samples with different characteristics, having determined its p H, humidity, content of chloride and sulphates as well as the presence of S RB. Although the main obstacle to understand its ecology and diversity is the incapacity to cultivate many of the microorganisms that come from environmental samples, this difficulty can directly be avoided by means of the use of molecular techniques that allow the study of the microorganisms present or their genes. In this work we correlate the detection of sulphate reducing bacteria by classic and molecular methods in the different soils studied

    To illustrate how the tobacco industry' front group, the International Tobacco Growers Association (ITGA), mobilised tobacco farmers to influence the fourth session of the Conference of the Parties (COP4) negotiations and defeat the adoption of Framework Convention on Tobacco Control Articles 9 and 10 Guidelines and Articles 17 and 18 progress report. A review of COP4 documents on Articles 9, 10, 17 and 18 was triangulated with relevant information from tobacco industry reports, websites of British American Tobacco, Philip Morris International and ITGA, presentations by tobacco industry executives and internal industry documents from the Legacy Tobacco Documents Library website. Philip Morris International and British American Tobacco rejected Articles 9 and 10 draft Guidelines claiming that banning ingredients in cigarettes will render burley leaf less commercially viable making tobacco growers in many countries suffer economic consequences. They claimed the terms 'attractiveness' and 'palatability' are not appropriate regulatory standards. The ITGA launched a global campaign to mobilise farmers to reject the draft Guidelines at COP4 in Uruguay. Tobacco producers, Brazil, Philippines, Tanzania, Zambia, Malawi and Zimbabwe, sent large delegations to COP4 and participated actively in the negotiation on the draft Guidelines. Partial Guidelines on Articles 9 and 10 on product regulation and disclosure were adopted. COP4's work on Article 17 provides guidance on viable alternatives, but the ITGA is opposed to this and continues fight crop substitution. Despite ITGA's international campaign to thwart the Guidelines on Articles 9 and 10 and a strong representation from tobacco-growing countries at COP4, the outcome after intense negotiations was the adoption of Partial Guidelines and work on Articles 17 and 18 to proceed.

    This article claims that welfare states modelled on a contributory basis and with a system of entitlements that assumes stable two-parent families, a traditional breadwinner model, full formal employment and a relatively young age structure are profoundly flawed in the context of present-day challenges. While this is true for affluent countries modelled on the Bismarckian type of welfare system, the costs of the status quo are even more devastating in middle-income economies with high levels of inequality. A gendered approach to welfare reform that introduces the political economy and the economy of care and unpaid work is becoming critical to confront what may very well become a perfect storm for the welfare of these nations and their peoples. Through an in-depth study of the Uruguayan case, the authors show how the decoupling of risk and protection has torn asunder the efficacy of welfare devices in the country. An ageing society that has seen a radical transformation of its family and labour market landscapes, Uruguay maintained during the 1980s and 1990s a welfare state that was essentially contributory, elderly and male-oriented, and centred on cash entitlements. This contributed to the infantilization of poverty, increased the vulnerability of women and exacerbated fiscal stress for the system as a whole. Furthermore, because of high levels of income and asset inequality, the redistribution of risk between upper- and lower-income groups presented a deeply regressive pattern. The political economy of care and welfare has begun to change in the last decade or so, bringing about mild reforms in the right direction; but these might prove to be too little and too late.

    This article analyzed the demand for meats at household level over the past decade in Uruguay, a country that exhibits a very high per capita consumption of these products. In particular, the consumption of beef is one of the highest in the world and only comparable to Argentina. The analysis involved a two-step estimation of an incomplete system of censored demand equations using household data from the last available national income and expenditure survey (2005/06). Thirteen meat products were included in the analysis: six broad beef products (de boned hindquarter cuts, bone-in hindquarter cuts, ground beef, rib plate, bone-in forequarter cuts, and other beef cuts), four products from other meats (sheep, pork, poultry, and fish), and three generic mixed-meat products. A complete set of short-term income, own-price and cross-price elasticities were computed and reported along with their 90% confidence intervals (CI). The results were consistent with both economic theory and empirical evidence as well as with the expected behavior, considering the relevance of these products, particularly beef, in the diet of Uruguayan consumers. All meat items were necessary goods and evidenced income-inelastic responses, which was expected given their high consumption level. All meats behaved as normal goods although exhibiting different reactions to changes in price. In general, beef cuts were more price elastic than other more broadly defined products. The more specific and dis aggregated the meat product the higher its corresponding direct price elasticity. The complement/substitute relationships found in this study were highly depended on the specific product combinations. (Author)

    Full Text Available The development of cattle farming has influenced and modeled the social and economic organization of Uruguay along history and has culturally acquired several expressions, including decisive evidence in the historical organization of its territory and the conformation of its rural landscape. The historic marks of cattle farming are key to understand the logics of land use planning and the natural-culturalconstruction of the Uruguayan landscape and have exerted great influence on the country’s internal policy organization, the division of land, the organization of roads and trails, its toponymy, etc. From the modifications of flora and fauna caused by the first introduction of cattle in the country, the conformation of the rural landscape of our territory has been linked to cattle farming, especially to the economic unit represented by the “estancia ganadera” (cattle farm. Its historic evolution delineated processes for land occupancy, holding and exploitation which lasted very long periods and with the so called “modernization of cattle farming” established the way and typology of rural architecture as well as forestry treatment and equipment which defined the predominant profile of rural areas in the country. The estate systems related to the industrialization of meat, which resulted from the productive situation of the country in the 70’s are also as significant, although their territorial dimension is much less. These industrial remains (unequally preserved, recognized and restored require to be approached as cultural landscapes and demand the set up of their links with the territory and the productive chain. This approach focuses on recognizing and activating the most significant elements of this cultural heritage, integrating its management to cattle farming today and to sustainable strategies of local and regional productive development.

    The oldest fossil vertebrates are from the Lower Cambrian Chengjiang biota of China, which contains four genera of fish-like, primitive vertebrates: Haikouichthys, Myllokunmingia, Zhongjianichthys and Zhongxiniscus. These fossils play key roles in calibrating molecular clocks and informing our view of the anatomy of animals close to the origin of vertebrates, potentially including transitional forms between vertebrates and their nearest relatives. Despite the evident importance of these fossils, the degree to which taphonomic processes have affected their anatomical completeness has not been investigated. For example, some or all might have been affected by stemward slippage - the pattern observed in experimental decay of non-biomineralised chordates in which preferential decay of synapomorphies and retention of plesiomorphic characters would cause fossil taxa to erroneously occupy more basal positions than they should. This hypothesis is based on experimental data derived from decay of non-biomineralised chordates under laboratory conditions. We have expanded this analysis to include a broader range of potentially significant environmental variables; we have also compared and combined the results of experiments from several taxa to identify general patterns of chordate decay. Examination of the Chengjiang vertebrates in the light of these results demonstrates that, contrary to some assertions, experimentally derived models of phylogenetic bias are applicable to fossils. Anatomical and phylogenetic interpretations of early vertebrates that do not take taphonomic biases into account risk overestimating diversity and the evolutionary significance of differences between fossil specimens.

  4. Preservation and phylogeny of Cambrian ecdysozoans tested by experimental decay of Priapulus

    The exceptionally preserved Cambrian fossil record provides unique insight into the early evolutionary history of animals. Understanding of the mechanisms of exceptional soft tissue preservation frames all interpretations of the fauna and its evolutionary significance. This is especially true for recent interpretations of preserved nervous tissues in fossil ecdysozoans. However, models of soft tissue preservation lack empirical support from actualistic studies. Here experimental decay of the priapulid Priapulus reveal consistent bias towards rapid loss of internal non-cuticular anatomy compared with recalcitrant cuticular anatomy. This is consistent with models of Burgess Shale-type preservation and indicates that internal tissues are unlikely to be preserved with fidelity if organically preserved. This pattern, along with extreme body margin distortion, is consistent with onychophoran decay, and is therefore resolved as general for early ecdysozoans. Application of these patterns to phylogenetic data finds scalidophoran taxa to be very sensitive to taphonomically informed character coding, but not panarthropodan taxa. Priapulid decay also have unexpected relevance for interpretation of myomeres in fossil chordates. The decay data presented serve not only as a test of models of preservation but also a framework with which to interpret ecdysozoan fossil anatomies, and the subsequent evolutionary inferences drawn from them.

  7. Replacement of benthic communities in two Neoproterozoic-Cambrian subtropical-to-temperate rift basins, High Atlas and Anti-Atlas, Morocco

    Clausen, Sébastien; Álvaro, J. Javier; Zamora, Samuel

    2014-10-01

    The ‘Cambrian explosion’ is often introduced as a major shift in benthic marine communities with a coeval decline of microbial consortia related to the diversification of metazoans and development of bioturbation (‘Agronomic Revolution’). Successive community replacements have been reported along with ecosystem diversification and increase in guild complexity from Neoproterozoic to Cambrian times. This process is recorded worldwide but with regional diachroneities, some of them directly controlled by the geodynamic conditions of sedimentary basins. The southern High Atlas and Anti-Atlas of Morocco record development of two rifts, Tonian (?) - early Cryogenian and latest Ediacarian-Cambrian in age, separated by the onset of the Pan-African Orogeny. This tectonically controlled, regional geodynamic change played a primary control on pattern and timing of benthic ecosystem replacements. Benthic communities include microbial consortia, archaeocyathan-thromboid reefal complexes, chancelloriid-echinoderm-sponge meadows, and deeper offshore echinoderm-dominated communities. Microbial consortia appeared in deeper parts of the Tonian (?) - early Cryogenian fluvio-deltaic progradational rift sequences, lacustrine environments of the Ediacaran Volcanic Atlasic Chain (Ouarzazate Supergroup) and the Ediacaran-Cambrian boundary interval, characterized by the peritidal-dominated Tifnout Member (Adoudou Formation). They persisted and were largely significant until Cambrian Age 3, as previous restricted marine conditions precluded the immigration of shelly metazoans in the relatively shallow epeiric parts of the Cambrian Atlas Rift. Successive Cambrian benthic communities were replaced as a result of distinct hydrodynamic and substrate conditions, which allow identification of biotic (e.g., antagonistic relationships between microbial consortia and echinoderms, and taphonomic feedback patterns in chancelloriid-echinoderm-sponge meadows) and abiotic (e.g., rifting

    Full Text Available La cobertura espacial de las redes de medición en tierra no puede satisfacer todas las necesidades de los usuarios debido a su baja densidad esto es más notable en el caso de la radiación solar. La escasez de datos de irradiación global es la razón para utilizar la heliofanía para su estimación mediante el empleo de diferentes correlaciones que han probado tener un buen ajuste con las mediciones. Para trazar cartas de heliofanía (y a partir de ellas, de irradiación solar global en un territorio tan extenso como América del Sur es necesario estudiar la relación error-distancia entre estaciones en zonas homogéneas. Para ello, lo habitual es analizar el comportamiento espacial de algunos estadísticos de campos aleatorios, como por ejemplo, la función estructura. En este trabajo, se han utilizado datos medios mensuales de heliofanía de Uruguay y se analizó su variación con la distancia entre estaciones. Se presentan gráficos obtenidos para diferentes épocas del año, analizándose las condiciones de extrapolación espacial de la información. Además, se muestran los resultados del análisis estadístico de series temporales de valores medios anuales de la heliofanía diaria mediante la aplicación del test de Mann-Kendall. Finalmente, se presentan 12 cartas con la distribución espacial de la media mensual de la heliofanía diaria.The spatial coverage of land measurement networks cannot fulfill all the user's needs because their density is low; and this fact becomes more important in the case of solar radiation. The scarcity of global irradiation data is the reason for using sunshine hours in order to estimate them through different correlations which have shown a good fit with the measurements data. In order to draw charts with the spatial distribution of the sunshine-hours monthly averages (and from them, global solar radiation charts also on such a vast territory as South America, it is necessary to study the error

    Cessation of tobacco use has the potential to provide the greatest immediate benefits for tobacco control. Understanding the social determinants of smoking cessation is an essential requirement for increasing smoking cessation at the population level. The purpose of this study was to analyze the socio-economic dimensions associated with cessation success among adults in Argentina and Uruguay. Data from the Global Adult Tobacco Survey (GATS), a cross-sectional, population-based, nationally representative survey conducted in Argentina (n=5,383) and Uruguay (n=4,833) was utilized. Univariable and multivariable logistic regression analyses with results being presented as odds ratios (OR) with 95% confidence intervals were applied to study differences among those respondents who sustained smoking abstinence (≥1 year) and those who continued smoking. The GATS study revealed that social gradients in tobacco quitting exist in Argentina and Uruguay. Being aged 25-34, particularly men in Uruguay, women in Argentina, low educated men in Argentina and having a lower asset index were associated with reduced odds for quitting. Factors that are driving differences in smoking cessation between diverse social groups in Latin America countries need to be considered when implementing relevant interventions to ensure tobacco control strategies work effectively for all population segments.

Las investigaciones arqueológicas de los años 60 y 70 confirman, a nivel arqueológico, la intensa ocupación de la que fue objeto esta zona próxima a la confluencia del río Paraná con el río Uruguay. Este trabajo presenta información producida durante un trabajo de diagnóstico realizado en el marco de la llamada Arqueología Pública, en un sitio de ocupación española del siglo XVI ubicado al oriente de dicha confluencia. Los resultados muestran que la ocupación del sitio desde el año 1000 AP está caracterizada por una amplia diversidad de estilos cerámicos. El área constituyó un lugar estratégico para los asentamientos europeos en función de la presencia de redes de intercambio pre existente. La información producida permite afinar la secuencia cronológica prehistórica para el bajo río Uruguay, al tiempo que abre el debate  respecto de la dinámica etnohistórica regional y del rol jugado por este particular asentamiento humano.   Palabras claves: asentamientos europeos, Uruguay, río San Salvador, siglo XVI.    Abstract Early chroniclers of the conquest of the Río de la Plata exposed the cultural diversity prevailing in the area in the sixteenth century.

This paper presents information recovered during a diagnostic fieldwork developed on a Spanish settlement from the sixteenth century. The results show an intense occupation of the site since 1000 AP, characterized by a wide variety of ceramic styles. The area was a strategic location for European occupation due to the presence of preexisting exchange networks. Information produced refines prehistoric chronological sequence for lower Uruguay river while opening the discussion about regional

    Full Text Available This study investigated the geochemical features of the lower Paleozoic strata of Yaerdang Mountain outcrop along with the core samples from well TD2∈ in the eastern Tarim Basin, NW China. The total organic carbon abundance, hydrocarbon-generating precursor biospecies, and stable isotope ratios of organics and carbonate (δ13Cker, δ13Ccarb and δ18Ocarb were comprehensively studied for their possible correlative constraints during sedimentary evolution. The results revealed that the δ13Cker (VPDB of Cambrian kerogens along the outcrop section varied from −34.6‰ to −28.4‰, indicating an increasing tendency from the lower Cambrian to the upper Cambrian. This was on the whole accompanied by the variation in the δ13Ccarb and δ18Ocarb along the profile, which might be associated with the changes in the sea level and also in the compositional variation of benthic and planktonic biomass. The large variation in the stable carbon isotope ratios up to 6‰ along the outcrop section reflected the heterogeneity of the Cambrian source rocks from the eastern Tarim Basin. Hence, the 13C-enriched crude oils from well TD2∈ might have been derived from a localized stratum of Cambrian source rocks. The results from this study showed the possibility of multiple source kitchens in the Cambrian–lower Ordovician portion of Tarim Basin.

    The cultivation of genetically modified (GM) Bt maize (Zea mays L.) events MON810 and Bt11 is permitted in Uruguay. Local regulations specify that 10% of the crop should be a non-GM cultivar as refuge area for biodiversity, and the distance from other non-GM maize crops should be more than 250 m in order to avoid cross-pollination. However, the degree of cross-fertilization between maize crops in Uruguay is unknown. The level of adventitious presence of GM material in non-GM crops is a relevant issue for organic farming, in situ conservation of genetic resources and seed production. In the research reported here, the occurrence and frequency of cross-fertilization between commercial GM and non-GM maize crops in Uruguay was assessed. The methodology comprised field sampling and detection using DAS-ELISA and PCR. Five field-pair cases where GM maize crops were grown near non-GM maize crops were identified. These cases had the potential to cross-fertilize considering the distance between crops and the similarity of the sowing dates. Adventitious presence of GM material in the offspring of non-GM crops was found in three of the five cases. Adventitious presence of event MON810 or Bt11 in non-GM maize, which were distinguished using specific primers, matched the events in the putative sources of transgenic pollen. Percentages of transgenic seedlings in the offspring of the non-GM crops were estimated as 0.56%, 0.83% and 0.13% for three sampling sites with distances of respectively 40, 100 and 330 m from the GM crops. This is a first indication that adventitious presence of transgenes in non-GM maize crops will occur in Uruguay if isolation by distance and/or time is not provided. These findings contribute to the evaluation of the applicability of the "regulated coexistence policy" in Uruguay. © ISBR, EDP Sciences, 2011.

  19. The age, nature and likely genesis of the Cambrian Khantaishir arc, Lake Zone, Mongolia

    Recent discovery of the huge Cambrian arc in the Khantaishir Mountain Range (SE Mongolian Altai) suggests that the principal Neoproterozoic and Devonian-Carboniferous episodes of crustal growth in the Central Asian Orogenic Belt (CAOB) (Sengör et al. 1993) have to be revised. This probably the largest arc system known in the Mongolian tract of the CAOB is seemingly intrusive into the Neoproterozoic accretionary wedge (the Lake Zone) in the N and underthrust southwards below the Palaeozoic volcanosedimentary prism (Gobi Altai Zone). The arc shows a section from deep, ultramafic cumulates to shallower crustal levels of the magmatic system and thus provides an excellent opportunity to study this important period of crustal growth in the Mongolian CAOB. The magmatic rocks are intermediate to ultrabasic (SiO2 = 39.2-61.8 wt. %), rather primitive (mg# = 45-60) Amp-Bt tonalites to coarse-grained Amp gabbros and hornblendites. They are Na-rich (Na2O/K2O = 1.3-9.7 by wt.), exclusively metaluminous and mostly subalkaline, except for the ultrabasic types that enter the alkaline domain due to accumulation of Amp crystals. The P-T conditions calculated using the Amp thermobarometer of Ridolfi et al. (2010) show that the gabbro crystallized at 930-950 ° C and 0.36-0.43 GPa. The (normal-) calc-alkaline chemistry and characteristic trace-element enrichment in hydrous-fluid mobile large-ion lithophile elements (LILE: Rb, Ba, Th, U, K and Pb) over high-field strength elements (HFSE: Nb and Ta) confirm an origin within an igneous arc. The newly obtained LA ICP-MS zircon ages for three tonalites-diorites range between 516 ± 2 Ma and 494 ± 3 Ma. While zircons in two of them give high initial ɛHf values (+8 to +14), implying a derivation by (near) closed-system fractionation from little modified, depleted-mantle derived magmas, the third contains significantly different component (ɛHf = +3 to +6). The latter component may have come from a distinct, less depleted

    Full Text Available She Middle Cambrian Borregård Member of Bornholm which is the stratigraphical equivalent to the Baltoscandian Exsulans Limestone yielded a rich and comparatively diverse ostracod fauna in its upper part. It comprises eight species out of four genera. They belong to three known subfamilies that are redefined on the basis of special characters of the contact margin. An ontogenetic character unknown from typical ostracods is documented in several species: during early ontogeny the gestalt (l:h ratio develops constantly in becoming increasingly longer until the so-called ontogenetical turning point (OTP from which the direction of growth focusses on carapace height. This phenomenon may be explained by changes in body morphology. The Borregård association represents an ecologic community type differing from other yet recorded Middle Cambrian communities in the Baltoscandic region. Apart from Vestrogothia longispinosa which is a common faunal element in Baltoscandian ostracod faunas, the yet recorded species of Bidimorpha are unknown from other Baltoscandian occurrences. Vice versa, the known species of Bidimorpha described from Swedish occurrences have not been recognized in the rich Borregård community. Similarly, Falites insula and Hesslandona abdominalis may be of local significance, too, but the respective records from contemporaneous Swedish localities are insufficient in this respect, yet. Due to specific morphological adaptations, the four genera are assumed to represent different benthic life strategies. New taxa are: Bidimorpha arator n. sp., Bidimorpha labiator n. sp., Bidimorpha sexspinosa n. sp., Falites insula n. sp., Hesslandona abdominalis n. sp., Vestrogothia herrigi n. sp. and Vestrogothia minilaterospinata n. sp.

  1. Depositional Architecture of Late Cambrian-Early Ordovician Siliciclastic Barik Formation; Al Huqf Area, Oman

    2017-04-01

    Early Paleozoic siliciclastics sediments of the Haima Supergroup are subdivided into a number of formations and members based on lithological characteristics of various rock sequences. One of the distinct sandstone sequence, the Barik Formation (Late Cambrian-Early Ordovician) of the Andam Group is a major deep gas reservoir in central Oman. The sandstone bodies are prospective reservoir rocks while thick shale and clay interbeds act as effective seal. Part of the Barik Formation (lower and middle part) is exposed in isolated outcrops in Al Huqf area as interbedded multistoried sandstone, and green and red shale. The sandstone bodies are up to 2 meters thick and can be traced laterally for 300 m to over 1 km. Most of sandstone bodies show both lateral and vertical stacking. Two types of sandstone lithofacies are identified on the basis of field characteristics; a plane-bedded sandstone lithofacies capping thick red and green color shale beds, and a cross-bedded sandstone lithofacies overlying the plane-bedded sandstone defining coarsening upward sequences. The plane-bedded sandstone at places contains Cruziana ichnofacies and bivalve fragments indicating deposition by shoreface processes. Thick cross-bedded sandstone is interpreted to be deposited by the fluvial dominated deltaic processes. Load-casts, climbing ripples and flaser-bedding in siltstone and red shale indicate influence of tidal processes at times during the deposition of the formation. This paper summarizes results of a study carried out in Al Huqf area outcrops to analyze the characteristics of the sandstone-body geometry, internal architecture, provenance and diagenetic changes in the lower and middle part of the formation. The study shows build-up of a delta complex and its progradation over a broad, low-angle shelf where fluvial processes operate beside shoreface processes in a vegetation free setting.

  2. Paleoarchean and Cambrian observations of the geodynamo in light of new estimates of core thermal conductivity

    Tarduno, John; Bono, Richard; Cottrell, Rory

    2015-04-01

    Recent estimates of core thermal conductivity are larger than prior values by a factor of approximately three. These new estimates suggest that the inner core is a relatively young feature, perhaps as young as 500 million years old, and that the core-mantle heat flux required to drive the early dynamo was greater than previously assumed (Nimmo, 2015). Here, we focus on paleomagnetic studies of two key time intervals important for understanding core evolution in light of the revisions of core conductivity values. 1. Hadean to Paleoarchean (4.4-3.4 Ga). Single silicate crystal paleointensity analyses suggest a relatively strong magnetic field at 3.4-3.45 Ga (Tarduno et al., 2010). Paleointenity data from zircons of the Jack Hills (Western Australia) further suggest the presence of a geodynamo between 3.5 and 3.6 Ga (Tarduno and Cottrell, 2014). We will discuss our efforts to test for the absence/presence of the geodynamo in older Eoarchean and Hadean times. 2. Ediacaran to Early Cambrian (~635-530 Ma). Disparate directions seen in some paleomagnetic studies from this time interval have been interpreted as recording inertial interchange true polar wander (IITPW). Recent single silicate paleomagnetic analyses fail to find evidence for IITPW; instead a reversing field overprinted by secondary magnetizations is defined (Bono and Tarduno, 2015). Preliminary analyses suggest the field may have been unusually weak. We will discuss our on-going tests of the hypothesis that this interval represents the time of onset of inner core growth.

    The Cambrian Mount Simon Sandstone is the major target reservoir for ongoing geologic carbon dioxide (CO2) sequestration demonstrations throughout the midwest United States. The potential CO2 reservoir capacity, reactivity, and ultimate fate of injected CO2 depend on textural and compositional properties determined by depositional and diagenetic histories that vary vertically and laterally across the formation. Effective and efficient prediction and use of the available pore space requires detailed knowledge of the depositional and diagenetic textures and mineralogy, how these variables control the petrophysical character of the reservoir, and how they vary spatially. Here, we summarize the reservoir characteristics of the Mount Simon Sandstone based on examination of geophysical logs, cores, cuttings, and analysis of more than 150 thin sections. These samples represent different parts of the formation and depth ranges of more than 9000 ft (>2743 m) across the Illinois Basin and surrounding areas. This work demonstrates that overall reservoir quality and, specifically, porosity do not exhibit a simple relationship with depth, but vary both laterally and with depth because of changes in the primary depositional facies, framework composition (i.e., feldspar concentration), and diverse diagenetic modifications. Diagenetic processes that have been significant in modifying the reservoir include formation of iron oxide grain coatings, chemical compaction, feldspar precipitation and dissolution, multiple generations of quartz overgrowth cementation, clay mineral precipitation, and iron oxide cementation. These variables provide important inputs for calculating CO2 capacity potential, modeling reactivity, and are also an important baseline for comparisons after CO2 injection. Copyright ??2011.

    The early Cambrian problematica Xianguangia sinica , Chengjiangopenna wangii , and Galeaplumosus abilus from the Chengjiang biota (Yunnan, China) have caused much controversy in the past and their phylogenetic placements remain unresolved. Here we show, based on exceptionally preserved material (85 new specimens plus type material), that specimens previously assigned to these three species are in fact parts of the same organism and propose that C. wangii and G. abilus are junior synonyms of X. sinica Our reconstruction of the complete animal reveals an extinct body plan that combines the characteristics of the three described species and is distinct from all known fossil and living taxa. This animal resembled a cnidarian polyp in overall morphology and having a gastric cavity partitioned by septum-like structures. However, it possessed an additional body cavity within its holdfast, an anchoring pit on the basal disk, and feather-like tentacles with densely ciliated pinnules arranged in an alternating pattern, indicating that it was a suspension feeder rather than a predatory actiniarian. Phylogenetic analyses using Bayesian inference and maximum parsimony suggest that X. sinica is a stem-group cnidarian. This relationship implies that the last common ancestor of X. sinica and crown cnidarians was probably a benthic, polypoid animal with a partitioned gastric cavity and a single mouth/anus opening. This extinct body plan suggests that feeding strategies of stem cnidarians may have been drastically different from that of their crown relatives, which are almost exclusively predators, and reveals that the morphological disparity of total-group Cnidaria is greater than previously assumed.

  5. Metamorphosis Is Ancestral for Crown Euarthropods, and Evolved in the Cambrian or Earlier.

    Macroevolutionary developmental biology employs fossilized ontogenetic data and phylogenetic comparative methods to probe the evolution of development at ancient nodes. Despite the prevalence of ecologically differentiated larval forms in marine invertebrates, it has been frequently presumed that the ancestors of arthropods were direct developers, and that metamorphosis may not have evolved until the Ordovician or later. Using fossils and new dated phylogenies, I infer that metamorphosis was likely ancestral for crown arthropods, contradicting this assumption. Based on a published morphological dataset encompassing 217 exceptionally preserved fossil and 96 extant taxa, fossils were directly incorporated into both the topology and age estimates, as in "tip dating" analyses. Using data from post-embryonic fossils representing 25 species throughout stem and crown arthropod lineages (as well as most of the 96 extant taxa), characters for metamorphosis were assigned based on inferred ecological changes in development (e.g., changes in habitat and adaptive landscape). Under all phylogenetic hypotheses, metamorphosis was supported as most likely ancestral to both ecdysozoans and euarthropods. Care must be taken to account for potential drastic post-embryonic morphological changes in evolutionary analyses. Many stem group euarthrpods may have had ecologically differentiated larval stages that did not preserve in the fossil record. Moreover, a complex life cycle and planktonic ecology may have evolved in the Ediacaran or earlier, and may have typified the pre-Cambrian explosion "wormworld" prior to the origin of crown group euarthropods. © The Author 2017.

    Four high-quality seismic reflection profiles through the southern Illinois Basin, totaling 245 km in length, provide an excellent regional subsurface stratigraphic and structural framework for evaluation of seismic risk, hydrocarbon occurrence, and other regional geologic studies. These data provide extensive subsurface information on the geometry of the intersection of the Cambrian Reelfoot and Rough Creek rifts, on extensive Proterozoic reflection sequences, and on structures (including the Fluorspar Area Fault Complex and Hicks Dome) that underlie a transitional area between the well-defined New Madrid seismic zone (to the southwest) and a more diffuse area of seismicity in the southern Illinois Basin. Our principal interpretations from these data are listed here in order of geologic age, from oldest to youngest: 1. Prominent Proterozoic layering, possibly equivalent to Proterozoic (???1 Ga) Middle Run Formation clastic strata and underlying (1.3-1.5 Ga) volcanic rocks of the East Continent rift basin, has been strongly deformed, probably as part of the Grenville foreland fold and thrust belt. 2. A well-defined angular unconformity is seen in many places between Proterozoic and Cambrian strata; a post-Grenville Proterozoic sequence is also apparent locally, directly beneath the base of the Cambrian. 3. We infer a major reversal in Cambrian rift polarity (accommodation zone) in the Rough Creek Graben in western Kentucky. 4. Seismic facies analysis suggests the presence of basin-floor fan complexes at and near the base of the Cambrian interval and within parts of a Proterozoic post-Grenville sequence in several parts of the Rough Creek Graben. 5. There is an abrupt pinchout of the Mount Simon Sandstone against crystalline basement beneath the Dale Dome (near the Texaco no. 1 Cuppy well, Hamilton County) in southeastern Illinois, and a more gradual Mount Simon pinchout to the southeast. 6. Where crossed by the seismic reflection line in southeast Illinois, some

    The radiometric ages obtained abroad have been systematically integrated with the field geology over the last thirty five years. The difference between the radiometric ages and their geochronology interpretation was realized rather early in the investigations. The few opportunities for radiometric determinations of rocks and minerals required careful regional geological mapping, based on models which were predominant at the time. Untial 1965, the pre-Devonian rocks in Uruguay were divided into Archean and Algonkian. The Archean units included medium metamorphic grade rocks and all the plutonic rocks. The Algonkian units were the low metamorphic grade supracrustal belts. The tectono-stratigraphic proposal presented at the International Geological Congress in India (1960) induced the division into two orogenic cycles and the radiometric dating with the techniques available at the time: K-Ar already in use and Rb-Sr isochrons, which were considered accurate and precise. The work of Hart (1966) resulted in ten ages, grouped in two geographically separated age sets: 600-500 Ma in the southeast and ca. 2000 Ma in the south and southwest. Bossi et al. (1967) identified two orogenic cycles based on geological mapping at the 1:250,000 scale, no intermediate ages. These cycles were recognized until 1991, although some improvements occurred in limits of units and cartography and some changes in nomenclature and integration of the Rb-Sr isotopic data by Umpierre and Halpern (1971), Soliani Jr. (1986), Renne (1991, pers. comm.). The proposal of a Trans-Amazonian craton in the west (Ciclo Orogenico Antiguo) and a mobile belt in the east (Ciclo Orogenico Moderno) was accepted for 25 years. Many Brazilian (e.g., Fragoso Cesar, 1980) and some Uruguayan authors included the 'Ciclo Orogenico Moderno in the Brasiliano Cycle of Almeida (1976). The consistency of this proposal has been accepted up to today, because 800-550 Ma granitic rocks are intruded in low metamorphic grade

    The Cambrian-Ordovician aquifer system contains the most extensive and continuous aquifers in the northern Midwest of the United States. It is the source of water for many municipalities, industries, and rural water users. Since the beginning of ground-water development from the aquifer system in the late 1800's, hydraulic heads have declined hundreds of feet in the heavily pumped Chicago-Milwaukee area and somewhat less in other metropolitan areas. The U.S. Geological Survey has completed a regional assessment of this aquifer system within a 161,000-square-mile area encompassing northern Illinois, northwestern Indiana, Iowa, southeastern Minnesota, northern Missouri, and Wisconsin.

    Gehrels, G.E.; Stewart, John H.

    1998-01-01

    One hundred and eighty two individual detrital zircon grains from Cambrian through Permian miogeoclinal strata, Ordovician eugeoclinal rocks, and Triassic post-orogenic sediments in northwestern Sonora have been analyzed. During Cambrian, Devonian, Permian, and Triassic time, most zircons accumulating along this part of the Cordilleran margin were shed from 1.40-1.45 and 1.62-1.78 Ga igneous rocks that are widespread in the southwestern United States and northwestern Mexico. Zircons with ages of approximately 1.11 Ga are common in Cambrian strata and were apparently shed from granite bodies near the sample site. The sources of 225-280 Ma zircons in our Triassic sample are more problematic, as few igneous rocks of these ages are recognized in northwestern Mexico. Such sources may be present but unrecognized, or the grains could have been derived from igneous rocks of the appropriate ages to the northwest in the Mojave Desert region, to the east in Chihuahua and Coahuila, or to the south in accreted(?) arc-type terranes. Because the zircon grains in our Cambrian and Devonian to Triassic samples could have accumulated in proximity to basement rocks near their present position or in the Death Valley region of southern California, our data do not support or refute the existence of the Mojave-Sonora megashear. Ordovician strata of both miogeoclinal and eugeoclinal affinity are dominated by >1.77 Ga detrital zircons, which are considerably older than most basement rocks in the region. Zircon grains in the miogeoclinal sample were apparently derived from the Peace River arch area of northwestern Canada and transported southward by longshore currents. The eugeoclinal grains may also have come from the Peace River arch region, with southward transport by either sedimentary or tectonic processes, or they may have been shed from off-shelf slivers of continents (perhaps Antarctica?) removed from the Cordilleran margin during Neoproterozoic rifting. It is also possible that the

    The precise, global correlation of Precambrian and Paleozoic sedimentary rocks can be achieved using temporally calibrated chemostratigraphic records. This approach is essential for determining rates and causes of environmental and faunal change, including mass extinctions. For example, The Neoproterozoic is marked by major environmental change, including periods of global glaciation, large fluctuations in the sequestration of carbon and major tectonic reorganization followed by the explosive diversification of animals in the earliest Cambrian. The extreme climatic change associated with these glaciations have been implicated as a possible trigger for the Cambrian explosion. The recognition of thin zircon-bearing air-fall ash in Neoproterozoic and Cambrian rocks has allowed the establishment of a high-precision temporal framework for animal evolution and is helping to untangle the history of glaciations. In some cases analytical uncertainties translate to age uncertainties of less than 1 Ma and when integrated with chemostratigraphy, the potential for global correlations at even higher resolution. Progress in the global correlation of Neoproterozoic strata has been achieved through the use of C and Sr isotope chemostratigraphy although it has been hampered by a lack of precise geochronological and faunal control. For example, the period from ca 800-580 Ma is characterized by at least two and perhaps as many as four glacial events that are interpreted by many to be global glaciations on a "Snowball Earth". A lack of precise chronological constraints on the number and duration of glaciations, multiple large excursions in the carbon isotopic record, and an absence of detailed biostratigraphy have complicated global correlation and hindered our understanding of this important period of Earth history. However, the ongoing integration of chemostratigraphic and geochronological data are improving temporal resolution and detailed correlations. These data are critical for

    In the northwestern border of the West African craton (North Gondwana), a transition from late Neoproterozoic subduction/collision to Cambrian rift processes was recorded in the Anti-Atlas (Morocco) and in the Ossa-Morena Zone (Iberia). Cambrian rifting affected both Pan-African and Cadomian basements in a stepwise and diachronous way. Subsequently, both areas evolved into a syn-rift margin episodically punctuated by uplift and tilting that precluded Furongian sedimentation. A comparison of sedimentary, volcanic and geodynamic evolution is made in the late Neoproterozoic (Pan-African and Cadomian) belts and Cambrian rifts trying to solve the apparent diachronous (SW-NE-trending) propagation of an early Palaeozoic rifting regime that finally led to the opening of the Rheic Ocean.

    Passive continental margins are geo-archives that store information from the interplay of endogenous and exogenous forces related to continental rifting, post-breakup history, and climate changes. The recent South Atlantic passive continental margins (SAPCMs) in Brazil, Namibia, and South Africa are partly high-elevated margins ( 2000 m a.s.l.), and the recent N-S-trending SAPCM in Argentina and Uruguay is of low elevation. In Argentina, an exception in elevation is arising from the higher topography (> 1000 m a.s.l.) of the two NW-SE-trending mountain ranges Sierras Septentrionales and Sierras Australes. Precambrian metamorphic and intrusive rocks, and siliciclastic rocks of Ordovician to Permian age represent the geological evolution of both areas. The Sierras Australes have been deformed and metamorphosed (incipient - greenschist) during the Gondwanides Orogeny. The low-temperature thermochronological (LTT) data (history of the Gondwanides and the Mesozoic and Cenozoic South Atlantic geological evolution. Upper Carboniferous zircon (U-Th/He)-ages (ZHe) indicate the earliest cooling below 180 °C/1 Ma. Most of the ZHe-ages are of Upper Triassic to Jurassic age. The apatite fission-track ages (AFT) of Sierras Septentrionales and the eastern part of Sierras Australes indicate the South Atlantic rifting and, thereafter. AFT-ages of Middle to Upper Triassic on the western side of the Sierras Australes are in contrast, indicating a Triassic exhumation caused by the eastward thrusting along the Sauce Grande wrench. The corresponding t-T models report a complex subsidence and exhumation history with variable rates since the Ordovician. Based on the LTT-data and the numerical modelling we assume that the NW-SE-trending mountain ranges received their geographic NW-SE orientation during the syn- to post-orogenic history of the Gondwanides.

    Full Text Available Referred to the new recognition from petroleum exploration of the Sinian to Cambrian in South China, it could be considered that the distribution of the early Cambrian source rocks was controlled by the palaeo-geomorphology at the end of Neoproterozoic in the Tarim Basin. Based on the zircon U-Pb dating of pyroclastic rock samples from the clastic rock stratum under the bottom of Cambrian carbonate rocks, the stratigraphic correlation of the Sinian to Cambrian was conducted to build the palaeo-geomorphology framework at the end of Neoproterozoic in Tarim Basin. Lastly, according to the development mode of source rocks at the beginning of Cambrian, the distribution of source rocks was predicted initially through the division of seismic facies. The youngest zircon concordia age of pyroclastic rocks from the bottom of well Tong 1 is 707±8Ma. It was revealed by the strata framework of the Sinian to Cambrian, the palaeo-geomorphology at the end of Neoproterozoic in Tarim Basin was characterized by an uplift highland in Bachu-Tazhong area, the south north high-low, and the west is higher than the east. The distribution of source rocks in the bottom of the Cambrian on the palaeo-platform and slopes was coincident with the Upper Sinian dolomite basically. But the contemporaneous sediment happened to be absent or changed in sedimentary facies on the uplift and its edges. From the seismic facies of the strata under the bottom of Cambrian, it could be concluded that source rocks in the type of the Xishanbraque Group (∈1xs was limited in the Manjiaer Depression, while the source rocks in the type of the Yuertusi Group (∈1y are widely distributed in south of Tabei Uplift, east Awat Depression, and even the Maigt Slope. However, among the west Awat Depression and western Tanguzibasi Depression, and the middle area of the Bachu-Tazhong Uplifts, the contemporaneous source rocks may have changed into sedimentary facies of tidal flat and lagoon, instead of

  8. A comparative assessment of the role of anoxia during the Cambrian SPICE event

    2017-12-01

    The Cambrian SPICE (Steptoean Positive Carbon Isotope Excursion) is recognized as a major oceanographic event recorded in globally-distributed stratigraphic sections as positive isotopic excursions in marine carbonates (δ13Ccarb), organic matter (δ13Corg), sulfate (δ34SCAS) and pyrite (δ34Spy). A proposed mechanism for these observed isotopic trends is that a transient increase in the areal extent of anoxic conditions within the oceans fostered enhanced burial of organic carbon and pyrite. However, direct sedimentary (e.g., abundant black shale) and geochemical (e.g., redox proxy) evidence for such a shift is scant. While the antiquity of this event is likely responsible for loss of much of this evidence, through destruction by tectonic processes, a number of stratigraphic successions suitable for investigating this hypothesis exist. Here we explore the relationship between anoxia and the SPICE using previously published and novel data generated from core material from three sedimentary basins distributed along the margins of the Iapetus Ocean. The units studied are: the Nolichucky Formation of eastern Laurentia, the Alum Shale of Baltica, and the Outwoods Shale of Avalonia. Our iron speciation data indicate consistently oxic conditions prior to the SPICE along Laurentia, while Avalonia was oxic with intervals of anoxia, and Baltica was persistently anoxic. With the initiation of the SPICE, anoxic conditions intensified in Laurentia and Avalonia and continued to persist in Baltica. This redox shift was coupled with a sharp rise in δ34Spy at all three locations. Average total organic carbon (TOC) showed little change in relation to the SPICE at the Laurentia location ( 0.15 wt%), but showed an increase in conjunction with the excursion in both the Avalonia ( 1 to 1.5 wt%) and Baltica ( 8 to 12 wt%) sections. Large differences in nutrient availability and sedimentation rates are likely responsible for the between-site disparity in TOC, while overall, anoxia

    Full Text Available The geologically rapid biotic evolution in the early Cambrian is marked by the first appearance of major groups of animals in the fossil record (e.g., Budd and Jensen 2000; Kouchinsky et al. 2012. Along with the earliest crown-group representatives of the phylum Brachiopoda, more basal branches of the phylogenetic tree belonging to the stem-group Brachiopoda, such as tannuolinids and mikwitziids, diversified and became widespread during the early Cambrian (e.g., Williams and Holmer 2002; Balthasar et al. 2009; Skovsted et al. 2014. Synchrotron-radiation X-ray tomographic microscopy (SRXTM of Oymurania gravestocki reveals the microstructure of its calcium-phosphatic shell differentiated into two layers and intersecting systems of canals. The outer layer shows the acrotretoid columnar microstructure and the inner layer consists of continuous prismatic columns. Phosphatized setae preserved within tangential canals, as well as perpendicular canals of Micrina–Setatella type demonstrate homology with the tannuolinid Micrina and the mickwitziid Setatella. A unique and novel combination of microstructural features in Oymurania confirms its evolutionary position within the brachiopod stem group.

  10. Disc-shaped fossils resembling porpitids or eldonids from the early Cambrian (Series 2: Stage 4 of western USA

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available The morphology and affinities of newly discovered disc-shaped, soft-bodied fossils from the early Cambrian (Series 2: Stage 4, Dyeran Carrara Formation are discussed. These specimens show some similarity to the Ordovician Discophyllum Hall, 1847; traditionally this taxon had been treated as a fossil porpitid. However, recently it has instead been referred to as another clade, the eldonids, which includes the enigmatic Eldonia Walcott, 1911 that was originally described from the Cambrian Burgess Shale. The status of various Proterozoic and Phanerozoic taxa previously referred to porpitids and eldonids is also briefly considered. To help ascertain that the specimens were not dubio- or pseudofossils, elemental mapping using energy dispersive X-ray spectroscopy (EDS was conducted. This, in conjunction with the morphology of the specimens, indicated that the fossils were not hematite, iron sulfide, pyrolusite, or other abiologic mineral precipitates. Instead, their status as biologic structures and thus actual fossils is supported. Enrichment in the element carbon, and also possibly to some extent the elements magnesium and iron, seems to be playing some role in the preservation process.

  11. Redox history of the Three Gorges region during the Ediacaran and Early Cambrian as indicated by the Fe isotope

    To circumvent this deficiency, we drilled a fossiliferous Ediacaran to Early Cambrian sedimentary succession in the Three Gorges region, South China. We analyzed the iron isotope ratios (δ56/54Fe of pyrite grains in the drill cores using laser ablation multi collector inductively coupled plasma mass spectrometry. The results demonstrate large variations in δ56/54Fe, from −1.6 to 1.6‰, and positive iron isotope ratios are observed in many successions. The presence of positive δ56/54Fe in pyrite indicates that the ferrous iron in the seawater was partially oxidized, suggesting that seawater at Three Gorges was ferruginous during the Ediacaran and Early Cambrian periods. However, aggregated pyrite grains in organic carbon-rich black shales at Member 4 of the Doushantuo Formation and the base of the Shuijingtuo Formation yield near-zero δ56/54Fe values; this suggests that the ocean was transiently dominated by sulfidic conditions during these periods. Notably negative δ56/54Fe values, lower than −1‰, can be interpreted as a signature of DIR. The DIR also might contribute in part to the re-mineralization of organic matter during the largest negative carbon isotope anomaly in the Ediacaran.

    The globally recognized Late Cambrian Steptoean positive C-isotope excursion (SPICE) is characterized by a 3???-5??? positive ??13C shift spanning SPICE represents a widespread ocean anoxic event leading to enhanced burial/preservation of organic matter (Corg) and pyrite. We analyzed ??18O values of apatitic inarticulate brachiopods from three Upper Cambrian successions across Laurentia to evaluate paleotemperatures during the SPICE. ??18O values range from ~12.5??? to 16.5???. Estimated seawater temperatures associated with the SPICE are unreasonably warm, suggesting that the brachiopod ??18O values were altered during early diagenesis. Despite this, all three localities show similar trends with respect to the SPICE ??13C curve, suggesting that the brachiopod apatite preserves a record of relative ??18O and temperature changes. The trends include relatively high ??18O values at the onset of the SPICE, decreasing and lowest values during the main event, and an increase in values at the end of the event. The higher ??18O values during the global extinction at the onset of the SPICE suggests seawater cooling and supports earlier hypotheses of upwelling of cool waters onto the shallow shelf. Decreasing and low ??18O values coincident with the rising limb of the SPICE support the hypothesis that seawater warming and associated reduced thermohaline circulation rates contributed to decreased dissolved O2 concentrations, which enhanced the preservation/burial of Corg causing the positive ??13C shift. ?? 2011 Geological Society of America.

    A three-dimensionally preserved 2-mm-long larva of the arthropod Leanchoilia illecebrosa from the 520-million-year-old early Cambrian Chengjiang biota of China represents the first evidence, to our knowledge, of such an early developmental stage in a short-great-appendage (SGA) arthropod. The larva possesses a pair of three-fingered great appendages, a hypostome, and four pairs of well-developed biramous appendages. More posteriorly, a series of rudimentary limb Anlagen revealed by X-ray microcomputed tomography shows a gradient of decreasing differentiation toward the rear. This, and postembryonic segment addition at the putative growth zone, are features of late-stage metanauplii of eucrustaceans. L. illecebrosa and other SGA arthropods, however, are considered representative of early chelicerates or part of the stem lineage of all euarthropods. The larva of an early Cambrian SGA arthropod with a small number of anterior segments and their respective appendages suggests that posthatching segment addition occurred in the ancestor of Euarthropoda.

    Cost-benefit analyses, run before the commencement of a programme to control a parasitic disease, should include estimates of the economic losses attributable to the disease. Uruguay, a middle-income, developing country, has a recent history of persistent problems with cystic echinococcosis, in both its human population and livestock. The economic effects in Uruguay of this disease, caused by the larval stage of the canine tapeworm Echinococcus granulosus, have now been evaluated. Data on the incidence of the disease, in humans and livestock, were used to construct cost estimates. The estimated minimum cost (U.S.$2.9 million/year) was based on the condemnation costs of infected offal together with the actual costs of the hospital treatment of the human cases. The estimate of the maximum cost (U.S.$22.1 million/year) also included the production losses resulting from lower livestock efficiency and the reduced income of individuals with morbidity attributable to the disease.

    Neonatal calf diarrhea (NCD), one of the most important diseases of neonatal dairy and beef calves in Uruguay, has become relevant in association with intensive systems. This disease generates substantial economic losses every year worldwide as a result of increased morbidity and mortality. Escherichia coli, one of the pathogens associated with NCD, can express several fimbrial and afimbrial adhesins. The objective of this study was to assess the presence of clpG, f5, f17A, f17G(II), and f17G(I) genes that encode three important adhesins expressed in diarrheagenic E. coli: F5, F17 and CS31A, isolated from feces of calves in Uruguay. Feces of 86 (70 diarrheic and 16 healthy) calves, from 15 animal facilities in Uruguay, were collected between 2012 and 2013. Biochemical and molecular identification were performed to finally obtain 298 E. coli isolates. Partial amplification of adhesion-related genes was performed by polymerase chain reaction. The most prevalent gene was f17A (31.2%), followed by f17G(II), clpG, f17G(I) and f5 (25.8%, 17.5%, 3.7% and 0.7%, respectively). All genes were present in diarrheic and healthy animals except f5 and f17G(I); these genes were present only in affected calves, although in low numbers. This is the first report of the presence of F5, F17, and CS31A genes in E. coli strains from NCD cases in Uruguay. Prevalence values of the genes, except f5, were in accordance with regional findings. It is expected that further characterization of locally transmitted strains will contribute to control a problem of regional and international magnitude.

    Uruguay and Bolivia are two countries that show heterogenicity of the Latin American region, including the national income, the expenditure on health and the services for renal care. In Bolivia, there is manpower shortage for renal care with only 5 nephrologists per million people (pmp) and the prevalence of patients on dialysis is only 200 pmp. This is much lower than the mean prevalence rate of renal replacement therapy for Latin America as a whole. Uruguay on the other hand has more dedicated renal resources with 50 nephrologists pmp, and renal replacement therapy is provided to ~ 1,000 dialysis patients pmp. In November 2012, a collaborative project financed by the Uruguayan International Cooperation Agency was signed by both the Uruguay and Bolivia Ministries of Health, and the goal was to develop a comprehensive program for the prevention and management of all stages of chronic kidney disease (CKD) in Bolivia. The specific objectives were to: a) promote renal healthcare in the primary healthcare setting, b) identify kidney disease in populations at risk, and c) optimize patient care at all stages of CKD, including dialysis and transplantation supported with a national ESRD registry in Bolivia. As a first step, delegates from the Bolivian Health Ministry, visited Uruguay in April 2014, primarily to strengthen the development of tools required for developing and maintaining a national registry. In addition, during this visit, a meeting with the president of the Latin American Society of Nephrology and Hypertension (SLANH) culminated in designing a training program for peritoneal dialysis. This highly cooperative relationship is advancing the prevention and care of CKD in Bolivia and may serve as a model for international approaches to advance system level CKD care in countries with limited healthcare resources.

    ABSTRACT Dental anomalies have been investigated and reported for most orders of mammals, including marsupials. Previous works in Didelphis albiventris Lund, 1840 only described one kind of malformation or just a few observations from some collections, thus the type and presence of anomalies for this species was underestimated. The aim of this contribution is to describe and analyze several dental anomalies found in specimens of Didelphis albiventris from Argentina, Uruguay and Brazil. Dental...

    After evaluating the Uruguay Round's impact on agriculture and border protection in the next decade, the author concludes that while there was significant reform of the rules - particularly the conversion of nontariff barriers into tariffs and the reduction and binding of all tariffs - in practice, trade will probably be liberalized less than expected. The objective of the Round was to reverse protectionism and remove trade distortions. This may not be achieved in practice, at least not until...

  15. Uruguay Roselli 1938 and Rosellichnus, N. Ichnogenus: Two ichnogenera for clusters of fossil bee cells

    Genise, Jorge F.; Bown, Thomas M.

    1996-01-01

    The systematics of the fossil bee nest ichnogenus Uruguay from the Uruguayan Cretaceous or lower Tertiary is reviewed and two new ichnospecies of a new ichnogenus, Rosellichnus, are proposed for fossil bee nests from the Miocene of the United Arab Emirates and Patagonian Argentina. Uruguay contains U. auroranormae(the ich‐notype) and U. rivasi, which differs from the type ichnospecies in having clustered cells arranged in three rows, with one central and two marginal rows of subparallel cells. No bee nest architecture known to us unequivocally fits with any ichnospecies described herein. Uruguay was constructed in the subsoil and may be of halictid origin; however, its large cell size, thick cell walls, and the presence of a vestibular cell do not fit the architecture of nests of extant halictids. Rosellichnus arabicus lacks the complete cavity surrounding the cell cluster that is typical in nests of Old World halictids, but it may, nonetheless, still be of halictid origin. R. pa‐tagonicus has an architecture more similar to nests of anthophorine bees than to those of Neotropical Halictidae. Therefore, the ichnogenus Rosellichnus may include both halictid and anthophorine constructions. Although the smooth inner cell walls, spiral cell caps, and clustering of cells indicate that both Uruguay and Rosellichnus are trace fossils of bee origin, it is likely that both represent nest architectures that are no longer employed by extant bees, or those that are as yet unknown. The paleoenvironments of both the Argentine and Emirates species of Rosellichnus indicate that the trace‐makers of this ichnogenus constructed their nests in open ground sandy soils.

    This paper analyzes the role of the sharply increases in the minimum wage after 2004 in Uruguay in the slight decrease on wage inequality. We Önd no impact of the miminum wage increases on wage inequality. This results can be explained by the low starting level of the minimum wage or lack of compliance with it. The Uruguayan experience shows that the minimum wage is not always e§ective as a redistribution instrument.

    Full Text Available La necesidad de proteger el medio ambiente y en especial la cantidad y la calidad de las fuentes de agua dulce contra los efectos de las presiones naturales y antrópicas se ha vuelto cada vez más importante a nivel mundial. Para ello, no basta con aplicar tecnologías de extracción de agua y de depuración efectivas, sino que también se debería implementar sistemas de gestión participativos para alinear las actividades humanas hacia el desarrollo sostenible. La herramienta más idónea para realizarlo es la Gestión Integrada de Recursos Hídricos (GIRH mediante la cual se genera información sobre la que basar políticas de gestión ambiental y de provisión de agua potable y saneamiento equitativas, que contemplen las opiniones de todos los grupos de interés. En el caso de Uruguay, la Constitución de la República consagra el derecho de todos los habitantes del país al acceso al agua y al saneamiento. El proceso de implementación del sistema de GIRH se inició dándole participación a la ciudadanía a través de un referéndum, luego del cual los referentes en el tema de todos los sectores de la sociedad aconsejaron a nivel parlamentario, y el procesó derivó en la reglamentación de la ley del agua. Se consolidó así una estructura de gestión por cuencas hidrográficas basada en el ciclo hidrológico que se encuentra hoy en un grado de desarrollo que refleja la mejora continua de la institucionalidad de la gobernanza del agua. En esta revisión se releva el desarrollo de estos procesos tanto a nivel nacional como mundial y se propone una serie de herramientas y estrategias para hacer cada vez más eficiente la gobernanza.

  1. Mineral chemical and petrographic occurrences os iron of the south east of Uruguay (Nico Pere z terrane)

    Two iron-formation deposits from S E Uruguay were petrographic ally and mineralogically investigated (including microprobe mineral chemistry). The deposit from Piedra de Gigante (ANCAP) quarry is related to tectonic slivers of a platform succession in ortho gneiss of ca. 1750 Ma. Data of detrital zircon in this platform succession point to Meso- to Neo proterozoic age.The iron deposit of Piedra del Gigante (ANCAP) quarry belongs to a succession of mica schists, quartz-muscovite schists, marbles and basic rocks. Magnetite rich layers alternate with banded rocks rich in hematite, carbonate and amphibole. Carbonate is dolomite (Mg0.7Ca1.08Mn0.05Fe0.11(CO3)2) and the amphibole is a pale green tremolite (Na0,18Ca1,68Mn0,07Mg4,16Fe+++0,2Fe++0,55Al0,03(Si7,86Al0,13)O22(OH)2). This iron deposit shows strong deformation associated with martitization of magnetite and formation of specularite rich layers where relicts of magnetite (partly martitized) are occasionally observed. Available data are not conclusive about the genesis. The low iron-content of the amphibole together with dolomite in the mineral association cast doubts on a BIF-type origin, but low contents of Al2O3, V2O3, MnO and ZnO in magnetite do not indicate an igneous origin. High oxygen fugacity during martitization in medium-T metamorphic conditions could have determined that iron rich amphiboles were not formed as is normally expected in iron-formations. In the outcrop of Cerro la Higuerita (Grupo Arroyo del Soldado; Ediacaran) a succession of metapelites (bottom), iron rich pelites and iron formations (top) is observed. The metapelites contain evidences of volcanic contribution (phenochrysts of quartz and alkali feldspar as well as shards in the matrix) suggesting a volcanic source for the iron. This iron-formation contains magnetite pheno blasts (partly martitized) and fine disseminated laths of hematite in the matrix, together with grunerite (Na0,04Ca0,17 Mn0,02Mg1,36Fe5,35Al0,07(Si7,97Al0,03)O22(OH)2

    This paper describes a procedure for predicting seasonal flow in the Rio Uruguay drainage basin (area 75,000 km2, lying in Brazilian territory), using sequences of future daily rainfall given by the global climate model (GCM) of the Brazilian agency for climate prediction (Centro de Previsão de Tempo e Clima, or CPTEC). Sequences of future daily rainfall given by this model were used as input to a rainfall-runoff model appropriate for large drainage basins. Forecasts of flow in the Rio Uruguay were made for the period 1995-2001 of the full record, which began in 1940. Analysis showed that GCM forecasts underestimated rainfall over almost all the basin, particularly in winter, although interannual variability in regional rainfall was reproduced relatively well. A statistical procedure was used to correct for the underestimation of rainfall. When the corrected rainfall sequences were transformed to flow by the hydrologic model, forecasts of flow in the Rio Uruguay basin were better than forecasts based on historic mean or median flows by 37% for monthly flows and by 54% for 3-monthly flows.

In this secondary analysis of a trial to implement brief smoking cessation counseling during antenatal care in Argentina and Uruguay, we aim to evaluate the effects of the intervention on the rates of self-reported SHS exposure at home and at work, and on attitudes recalled by non-smoker women enrolled in the intervention group compared with the control group. We randomly assigned (1:1 20 antenatal care clusters in Argentina and Uruguay to receive a multifaceted intervention to implement brief smoking cessation counseling, which also included questions and counseling regarding SHS exposure, or to receive the standard of care. There was not a statistically significant difference between groups of the intervention’s effect (reduction of exposure to SHS on any of the three exposure outcome measures (exposure at home, work or other indoor areas or on the attitudes of women regarding exposure (avoiding breathing SHS and having rooms where smoking is forbidden. This analysis shows that we should not expect reductions in SHS exposure with this modest intervention alone. To achieve such reductions, strategies engaging partners and other household members may be more effective.

    To investigate and describe the prevalence and causes of blindness and moderate and severe visual impairment in older adults living in Uruguay. All individuals aged ≥ 50 years old living in randomly selected clusters were eligible to participate. In each census enumeration unit selected, 50 residents aged 50 years and older were chosen to participate in the study using compact segment sampling. The study participants underwent visual acuity (VA) measurement and lens examination; those with presenting VA (PVA) glaucoma (14.3%) were the main causes of blindness. Prevalence of SVI and MVI was 0.9% (95% CI: 0.5-1.3) and 7.9% (95% CI: 6.0-9.7) respectively. Cataract was the main cause of SVI (65.7%), followed by uncorrected refractive error (14.3%), which was the main cause of MVI (55.2%). Cataract surgical coverage was 76.8% (calculated by eye) and 91.3% (calculated by individual). Of all eyes operated for cataract, 70.0% could see ≥ 20/60 and 15.3% could not see 20/200 post-surgery. Prevalence of blindness in Uruguay is low compared to other Latin American countries, but further reduction is feasible. Due to Uruguay's high cataract surgical coverage and growing proportion of people ≥ 50 years old, the impact of posterior pole diseases as a contributing factor to blindness might increase in future.

    Full Text Available ABSTRACT: In Eastern Uruguay there has been a significant increase of seneciosis in grazing livestock with most affected localities related to counties neighboring the Brazilian border. A survey in 28 farms associated with poisoning outbreaks in grazing cattle in Eastern Uruguay was carried out. Fifty populations of Senecio plants were collected for alkaloid analysis and species identification. Four species were identified: S. oxyphyllus DC, S. madagascariensis Poir, S. brasiliensis (Spreng. Less., and S. selloi DC. Alkaloids were identified by a combination of GC-MS and HPLC-MS analysis and included: retrorsine in S. oxyphyllus; retrorsine, usaramine, and senecivernine/senecionine in S. selloi; retrorsine, senecivernine/senecionine, integerrimine, and usaramine in S. madagascariensis; and integerrimine, retrorsine and senecionine in S. brasiliensis. Total mean alkaloid concentration was reported to be highest in S. brasiliensis (17.6mg/g followed by S. oxyphyllus (6.2mg/g, S. selloi (1.8mg/g and S. madagascariensis (0.6mg/g. Alkaloid concentrations were also reported to be higher in 2015 vs. 2016 probably due to a common environmental factor. The species S. oxyphyllus and S. madagascariensis were not previously recognized as toxic plants in Eastern Uruguay. Particularly, S. oxyphyllus was present in 82% of the farms surveyed and occurred in high density with relative high concentrations of pyrrolizidine alkaloids suggesting S. oxyphyllus may be the main species involved in the reported outbreaks of seneciosis.

METHODS In this case study, the following aspects were analyzed: 1 historical background; 2 implementation of Law 18,897 of October 22, 2012; and 3 functioning of the program at the Hospital de Clínicas of the Facultad de Medicina (Universidad de la República, Uruguay, taking into account three dimensions: structure, process, and results. RESULTS Between December 2012 and November 2013, a total of 6,676 voluntary interruptions of pregnancy were reported in Uruguay; out of these, 80 were conducted at the Hospital de Clínicas. The patients’ demographic data agreed with those reported at the national level: Of the total patients, 81.0% were aged over 19 years; 6.2% decided to continue with the pregnancy; and only 70.0% attended the subsequent control and received advice on contraception. CONCLUSIONS In its implementation year in Uruguay, we can assess the experience as positive from the point of view of women’s health. Our experience as a mental health team at the Hospital de Clínicas, inserted into the multidisciplinary voluntary interruption of pregnancy team, is in the process of assessment and reformulation of practices.

    According to estimates by the UICC 2020 the annual number of new cases cancer worldwide will reach 20 million, of which 14 occur in developing countries, which must address the problem with little human and material resources. This increase, in particular the care burden will weigh in countries development, is the result, among other factors, the transition patterns epidemiological, accompanied by an increase in life expectancy at birth. This determines the prevalence of chronic and degenerative diseases within which highlights the cardiovascular and oncological diseases. In Uruguay, the life expectancy at birth has increased from 45 in 1900-75 to end of the century. In parallel we are witnessing a progressive aging of the population, with an increasing proportion of older age groups. taking population aged 65 or more, it represented 4.5% in 1908 and reached 21.2% in 2000 Similarly, cancer mortality has increased percentage, in 2001 representing 23.8% of total deaths. Depending on age, analyzed the increased risk of developing or dying from cancer in Uruguay and its impact is weighted mortality of seven locations more frequent. For each of these locations the percentage of deaths in the population of 65 or more years is as follows: lung 60.9%, breast 60.3%, prostate 91.4%, colorecto 78.3%, 72.3% stomach, esophagus 70.3%, 72.2% pancreas, averaging 69.4% overall.

    Bovine abortions due to Neospora caninum infection have been reported worldwide and its economic impact on the beef industry has been acknowledged as a problem. Uruguay has the largest export value of beef per acre in South America. However, no data on the prevalence of N. caninum infection have been available in this country. The objective of this study was to estimate the prevalence and distribution of N. caninum infection in beef cattle in Uruguay through a nationwide survey. A two stage sampling design was used with farms being selected in stage one and animals being selected in stage two. A brief questionnaire was administered on each farm. Seroprevalence of N. caninum in 4444 beef cattle from 229 farms in all the counties, except Montevideo, of Uruguay was determined by an ELISA. The data were then analyzed to identify associations between infection and variables such as type of animal (cow or heifer), herd size, use of veterinary advice, productivity of the soil in relation to the national average, use of improved grass, use of mineral salts, use of supplemental feed, and presence of a dog(s) on the farm. The estimated proportion of positive farms for all the beef cattle operations was 69.2% (95% confidence interval [CI], 53.7-84.7). The overall cattle seroprevalence was estimated as 13.9% (95% CI, 11.6-16.3). The prevalence estimation by animal category was 14.3% (95% CI, 11.4-17.2) for beef cows and 12.9% (95% CI, 10.0-15.8) for beef heifers. There was no significant difference in the estimated prevalence between the two animal types. There was no significant difference in the animal level prevalence of N. caninum infection among different herd sizes. None of the herd demographic or management variables was significantly associated with the seropositivity to N. caninum infection. In conclusion, these results show that N. caninum infection is common among beef herds across Uruguay. Since the beef industry is one of the key industries in Uruguay, the

    The Tiantaishan phosphorite-Mn carbonate ores occur in the Early Cambrian Tananpo Formation in complexly folded and faulted rocks located in southern Shaanxi Province. About 65 x 106 tonnes of 17% P2O5 ore reserves exist and Mn-ore reserves are about 8.3 x 106 tonnes of +18% Mn. The stratigraphic sequence in ascending order consists of black phyllite, black to gray phosphorite ore, black phyllite, rhodochrostone ore, Mn mixed-carbonates, and dolostone. Data are presented from microprobe mineral chemistry, whole-rock chemistry, stable isotopes of carbonates, X-ray mineralogy, petrographic and SEM observations, and statistical analysis of chemical data. The dominant ore-forming minerals are hydroxy- and carbonate fluorapatite and Ca rhodochrosite, with Mg kutnahorite and dolomite comprising the Mn mixed-carbonate section. Pyrite occurs in all rock types and alabandite (MnS) occurs throughout the rhodochrostone section. The mean P2O5 content of phosphorite is 31% and argillaceous phosphorite is 16%, while the mean MnO content of rhodochrostone ore is 37%. Phosphorite ores are massive, spheroidal, laminated, and banded, while rhodochrostone ores have oolitic, spheroidal, and granular fabrics. The most distinguishing characteristics of the ores are high total organic carbon (TOC) contents (mean 8.4%) in the phosphorite and high P2O5 contents (mean 2.7%) in the rhodochrostone ore. The atypically high TOC contents in the Tiantaishan phosphorite probably result from very strong productivity leading to high sedimentation rates accompanied by weak reworking of sediments; poor utilization of the organic matter by bacteria; and/or partial replacement of bacterial or algal mats by the apatite. The depositional setting of the ores was the margin of an epicontinental seaway created as a direct consequence of global processes that included break-up of a supercontinent, formation of narrow seaways, creation of extensive continental shelves, overturn of stagnant, metal-rich deep

    Full Text Available En Uruguay, desde el inicio de la década del treinta hasta mediados de los años cincuenta, se desarrolló el modelo industrial sustitutivo de importaciones. El cambio en la estructura productiva tuvo consecuencias en el mercado laboral, influenciado por el rol protector del Estado, fundamentalmente desde la llegada del denominado neobatllismo. Con el desarrollo industrial y sus consecuencias sociales, la legislación laboral y social cobró impulso mejorando las condiciones de vida y trabajo en el medio urbano, deterioradas como consecuencia del período de crisis anterior. El resultado fue la innovación en materia de negociación colectiva creándose los Consejos de Salarios tripartitos, como el escenario del Sistema de Relaciones Laborales. El objetivo de esta investigación consiste en analizar la evolución del salario real en las rondas inaugurales de los Consejos de Salarios, en el Uruguay en la década del cuarenta, para cuatro industrias seleccionadas: la del cuero y fabricación de calzado, la química, del caucho y la industria gráfica; así como también las diferencias salariales existentes entre las distintas calificaciones de los trabajadores agrupadas en tipos de ocupación. Como principal resultado se constató el incremento del salario real tanto en todos los grupos analizados. Los salarios de los trabajadores con categorías de obreros, los menos calificados, tuvieron mayores aumentos salariales respecto a los agrupados en la definición de empleados, con mayor calificación. La discriminación de género siguió haciéndose efectiva mediante diferenciaciones salariales y estipulación de salarios diferenciados entre mujeres y hombres para categorías laborales con idénticas tareas asignadas.

    Objective To assess the impact of different health warning labels (HWL). Material and Methods Data from the International Tobacco Control Survey (ITC Survey) were analyzed from adult smokers in Brazil, Uruguay and Mexico, each of which used a different HWL strategy (pictures of human suffering and diseased organs; abstract pictorial representations of risk; and text-only messages, respectively). Main outcomes were HWL salience and cognitive impact. Results HWLs in Uruguay (which was the only country with a HWL on the front of the package) had higher salience than either Brazilian or Mexican packs. People at higher levels of educational attainment in Mexico were more likely to read the text-only HWLs whereas education was unassociated with salience in Brazil or Uruguay. Brazilian HWLs had greater cognitive impacts than HWLs in either Uruguay or Mexico. HWLs in Uruguay generated lower cognitive impacts than the text-only HWLs in Mexico. In Brazil, cognitive impacts were strongest among smokers with low educational attainment. Conclusions This study suggests that HWLs have the most impact when they are prominent (i.e., front and back of the package) and include emotionally engaging imagery that illustrates negative bodily impacts or human suffering due to smoking.

    2012-09-01

    Full Text Available The fact that several half-grabens and normal faults developed in the Lower–Middle Cambrian of Tazhong (central Tarim Basin and Bachu areas in Tarim Basin, northwest China, indicates that Tarim Basin was under extensional tectonic setting at this time. The half-grabens occur within a linear zone and the normal faults are arranged in en echelon patterns with gradually increasing displacement eastward. Extensional tectonics resulted in the formation of a passive continental margin in the southwest and a cratonic margin depression in the east, and most importantly, influenced the development of a three-pronged rift in the northeast margin of the Tarim Basin. The fault system controlled the development of platform – slope – bathyal facies sedimentation of mainly limestone-dolomite-gypsum rock-saline rock-red beds in the half-grabens. The NW-SE trending half-grabens reflect the distribution of buried basement faults.

    The post-Pan-African evolution of the northern border of the West African Craton is largely controlled by the remobilisation of Late Neoproterozoic basement faults. The Upper Ediacaran volcanic and volcano-sedimentary sequences of the Ouarzazate Group show dramatic and rapid thickness changes, consistent with active extensional faulting associated with post-orogenic collapse and incipient continental rifting. The geometry and kinematics of these faults differ from west to east in the Anti-Atlas. N- to NE-trending faults dominate in western Anti-Atlas in response to E-W to NW-SE pure extension, while a transtensive opening regime characterize the central (Bou Azzer) and eastern (Saghro-Ougnate) Anti-Atlas. The marine incursion in the west-central Anti-Atlas during the late Ediacaran-Early Cambrian occurred without major geodynamical break between the continental Ouarzazate Group and marine sediments of the Adoudou Fm. Extensional tectonics went on during the Early Cambrian, being concentrated in the western and central parts of the belt. From Middle Cambrian to Lower Devonian and mainly due to thermal subsidence, the Anti-Atlas basement was buried under marine sediments with dominant south-derived detrital input. Basement faults control the distribution of subsiding versus shallow areas. During the Middle-Late Devonian, the dislocation of the Saharan platform occurred, mainly in the eastern Anti-Atlas where Precambrian faults were also remobilized during the Early Carboniferous. During the Variscan orogeny, the Paleozoic series of the Anti-Atlas basin were involved in folding tectonics, concomitant with the uplift of Proterozoic basement blocks bounded by inherited basement faults. The pre-existing rift-related faults were variably inverted across the Anti-Atlas. In the westernmost part of the belt, Variscan shortening induced positive inversions along the remobilized basement faults, but in some cases, some faults preserved an apparently normal throw.

    Paleomagnetic data from Laurentia and Baltica continents suggest fast large oscillations of the virtual geomagnetic poles (VGP) from high to low latitudes during the Ediacaran (635-542 Ma). These data are interpreted in the literature either as oscillations of the Earth magnetic dipole between polar and equatorial positions, or as True Polar Wander (TPW), implying a very fast tumbling of continents and perhaps, of whole Earth. In this study, we try to test these hypotheses by bringing new paleomagnetic data on volcanic series from another continent, the West African Craton (WAC). We have sampled well dated pyroclastic and lava flows from the Ouarzazate and Taroudant groups in the Anti-Atlas, (Morocco). 480 samples from 105 sites were thermally demagnetized in our laboratory. Our preliminary results highlight two major groups of directions, mainly carried by hematite, magnetite also contributing sometimes to the magnetization. The first group consists of a dual polarity high inclination direction that may represent the original magnetization. The observed paleolatitude is compatible with that predicted by the lower Cambrian-Ediacaran apparent polar wander path (APWP) of Gondwana, assuming that the WAC was already accreted to Gondwana at this age. Nevertheless, a complete agreement between our pole and the APWP needs a local rotation of around 80° on a vertical axis. The second group displays a single polarity direction, with a shallow inclination and a south-east declination. This direction is close to the expected direction derived from the Permo-Carboniferous segment of the Gondwana APWP, and may represent a remagnetization acquired during the Kiaman reversed polarity superchron. Our preliminary paleomagnetic results thus display large changes in the VGP position, as also evidenced by others on Baltica and Laurentia. However, their interpretation does not favor TPW episodes or equatorial Earth magnetic dipole during the lower Cambrian-Ediacaran periods, but

    Full Text Available Combined with the regional strata filling characteristics of Middle-Upper Cambrian, the present paper conducts a systematic research on sedimentary facies in the basin and its peripheral area by utilizing 164 field outcrops and drilling and coring data. Further, the method of “multi-factor comprehensive synthesis based on single-factor analysis” was employed to investigate the sedimentary facies and palaeogeography of the study area and establish the sedimentary facies model. Stratigraphic reveals that the study area represents the pattern of thin-northwest and thick-southeast by stretching northeast-southwest. Within the present basin, the pattern of “one thin and two thick” predominates, while outside the basin “four thin and three thick” filling feature was found. Sedimentary facies shows that the study area was featured by rimmed carbonate platform. Specifically, carbonate platform, slope and northeastern corner Qinling paleooceanic Basin and southeastern corner Jiangnan Bain was identified from the west to the east. The carbonate platform contains restricted platform, evaporation-restricted platform, semi-restricted platform and the platform margin. Single factor analysis and lithofacies palaeogeographic characteristics manifests that during Middle-Late Cambrian, the western Old land evolved into peneplain stage, and that the eastern and southwestern sub-sags remained connected to the open-sea to some extent. At the time, the shllow seawater circulation was relatively restricted, while the ancient seabed tended to be flat and evaporation characteristics significantly diminished. Secondary sea-level fluctuation intensively influenced the development of scaled grain beach. It is suggested that tide marginal beach, intraplatform shoal subfacies zone, along with Shiqian-SangZhi in southeast and Zhenba-Xinshan in northeast platform-margin beach subfacies zone to be preferable targets for the favorable reservoir facies zone and

    The lower Cambrian grainy phosphorites of the northern Montagne Noire occur interbedded with grey to black, laminated to massive shales and limestones deposited along the edge of a continental shelf, associated with slope-related facies and unstable substrates. The concentration of phosphate took place by repeated alternations of low sedimentation rates and condensation (hardgrounds), in situ early-diagenetic precipitation of fluorapatite, winnowing and polyphase reworking of previously phosphatized skeletons and hardground-derived clasts. The succession of repeated cycles of sedimentation, phosphate concentration, and reworking led to multi-event phosphate deposits rich in allochthonous particles. Phosphogenesis was primarily mediated by microbial activity, which is evidenced by the abundance of phosphatized putative microbial remains. These occur as smooth and segmented filaments, sheaths, and ovoid-shaped coccoids. These simple morphologies commonly form composite frameworks as a result of their aggregation and entanglement, leading to the record of biofilms, microbial mats, and complex networks. These infested the calcitic skeletonized microfossils that littered the substrate. Microbial activity evidences epilithic (anisotropic coatings on skeletons), euendolithic (perforating skeletal walls), and cryptoendolithic (lining inter- and intraparticulate pores) strategies, the latter dominated by bundles of filaments and globular clusters that grew along the cavities of helcionellids and hyoliths. According to their epilithic versus cryptic strategies, microbial populations that penetrated and dwelled inside hard skeletal substrates show different network and colonial morphologies. These early Cambrian shell concentrations were the loci of a stepwise colonization made by saprophytic to mutualistic, cyanobacterial-fungal consortia. Their euendolithic and cryptoendolithic ecological niches provided microbial refugia to manage the grazing impact mainly led by metazoans.

Se revisó también la base de datos de la vigilancia nacional de resistencia a los antimicrobianos de los últimos 10 años, para estimar la frecuencia de la particularidad de los meningococos caracterizados. La resistencia a rifampicina se estudió por el método epsilométrico. El serotipo y serosubtipo de los aislamientos se determinaron por ELISA y la caracterización genotípica se realizó por digestión del ADN con NheI y electroforesis en gel con campo pulsátil. Ambos aislamientos eran idénticos, B:2a:P1.5, y su fenotipo no figuraba en la colección de 408 cepas de N. meningitidis aisladas en el Uruguay en los últimos 10 años, con la excepción de dos aislamientos sensibles a rifampicina. Los dos aislamientos estudiados también compartían un pulsotipo único, diferente del de otros dos aislamientos resistentes a rifampicina obtenidos en 2003 y 2007. Por lo tanto, ambos eventos de transmisión fueron causados por una única cepa resistente a rifampicina, que podría haberse introducido al país desde otras regiones o haberse originado por un cambio del serogrupo C al B, como producto de la presión selectiva ejercida por vacunas administradas a la población. Es necesario mantener y extremar la vigilancia. No obstante, en vista de que hasta el momento este tipo de hallazgo ha sido esporádico, no se justifica cambiar el fármaco antimicrobiano que se administra a los contactos para la profilaxis, a menos que se identifique un caso secundario.The objective of this study was to characterize the phenotype and genotype of two isolates of rifampicin-resistant Neisseria meningitidis associated with two independent events

    Full Text Available RESUMEN En el año 2005, poco tiempo después de ratificar el Convenio Marco para el Control del Tabaco (CMCT, Uruguay comenzó una ambiciosa campaña de control de tabaco que ubicó a este país a la vanguardia mundial de la lucha antitabaco. La gran diversidad de medidas implementadas en un lapso relativamente corto y la rigurosidad con que se aplicaron y observaron las políticas tienen escasos precedentes, incluso en los países más desarrollados. En este trabajo, se presenta una síntesis y actualización de varios trabajos de los autores en los que se evalúan algunos aspectos de la campaña a diez años de la ratificación del CMCT. En particular, estas investigaciones resaltan el impacto agregado que tuvo la campaña en la caída de la prevalencia en la población adulta, en los jóvenes y en las decisiones de abandono del consumo de tabaco en las embarazadas (1, 2, así como el impacto relativo de las políticas impositivas en relación a medidas de control de tabaco distintas de los precios. Los análisis se basan en estudios observacionales (a nivel de la población o el individuo que utilizan grupos de control externos (Argentina y Chile e internos (población no fumadora.

    International Nuclear Information System (INIS)

    1981-01-01

    The Government of Uruguay (Project Authorities)is desirous of improving their national economy through exploitation of resources with which the nation is endowed. Studies so far conducted in Uruguay reveal that the Valentine iron ore deposits amount to about 30 million tons with an average Fe-content of 331; an additional probable reserve of about 17 million tons is also expected. The Project Authorities have been examining the possibility of exploiting these iron reserves for the establishment of a viable iron and steel complex within the country.

    A succession of Devonian cover rocks occurs in outcrop and in the subsurface of central-northern Uruguay where they were deposited in an intracratonic basin. This Durazno Group comprises three distinct stratigraphic units, namely the Cerrezuelo, Cordobés and La Paloma formations. The Durazno Group does not exceed 300 m of average thickness and preserves a transgressive-regressive cycle within a shallow-marine siliciclastic shelf platform, and is characterized by an assemblage of invertebrate fossils of Malvinokaffric affinity especially within the Lower Devonian Cordobés shales. The sedimentary provenance of the Durazno Group was determined using petrography, geochemistry, and morphological studies of detrital zircons as well as their U-Pb ages. Sandstone petrography of Cerrezuelo and La Paloma sequences shows that they have a dominantly quartz-feldspathic composition with a minor contribution of other minerals. Whole-rock geochemical data indicate that alteration was strong in each of the three formations studied; chondritic-normalized REE patterns essentially parallel to PAAS, the presence of a negative Eu-anomaly, and Th/Sc and La/Hf ratios point to an average source composition similar to UCC or slightly more felsic. Within the Cerrezuelo Formation, recycling of older volcano-metasedimentary sources is interpreted from Zr/Sc ratios and high Hf, Zr, and REE concentrations. U-Pb detrital zircon age populations of the Cerrezuelo and La Paloma formations indicate that the principal source terranes are of Neoproterozoic age, but include also minor populations derived from Mesoproterozoic and Archean-Paleoproterozoic rocks. A provenance from the Cuchilla Dionisio-Dom Feliciano, Nico Pérez and Piedra Alta terranes of Uruguay and southern Brazil is likely. This study establishes an intracratonic extensional tectonic setting during Durazno time. Considering provenance age sources, regional paleocurrent distributions and the established orogenic history recorded in SW

    Smoke-free legislation eliminating tobacco smoke in all indoor public places and workplaces is the international standard to protect all people from exposure to secondhand smoke. Uruguay was the first country in the Americas and the first middle-income country in the world to enact a comprehensive smoke-free national legislation in March 2006. To compare air nicotine concentrations measured in indoor public places and workplaces in Montevideo, Uruguay before (November 2002) and after (July 2007) the implementation of the national legislation. Air nicotine concentrations were measured for 7-14 days using the same protocol in schools, a hospital, a local government building, an airport and restaurants and bars. A total of 100 and 103 nicotine samples were available in 2002 and 2007, respectively. Median (IQR) air nicotine concentrations in the study samples were 0.75 (0.2-1.54) microg/m(3) in 2002 compared to 0.07 (0.0-0.20) microg/m(3) in 2007. The overall nicotine reduction comparing locations sampled in 2007 to those sampled in 2002 was 91% (95% CI 85% to 94%) after adjustment for differences in room volume and ventilation. The greatest nicotine reduction was observed in schools (97% reduction), followed by the airport (94% reduction), the hospital (89% reduction), the local government building (86% reduction) and restaurants/bars (81% reduction). Exposure to secondhand smoke has decreased greatly in indoor public places and workplaces in Montevideo, Uruguay, after the implementation of a comprehensive national smoke-free legislation. These findings suggest that it is possible to successfully implement smoke-free legislations in low and middle-income countries.

  2. First approach to exhaust emissions characterization of light vehicles in Montevideo, Uruguay.

    2018-03-15

    According to Act No. 17283 of November 28th, 2000, air quality protection is a general concern in Uruguay. Road transport is the main emitter of nitrogen oxides (NO x ), as the National Inventory of Air Emissions 2006 stated. Actually, it is responsible for the emissions of 59.8% of NO x and 28% of carbon monoxide (CO). The number of households owning a car in Uruguay increased from 29% in 2005 to 39% in 2013, enhancing the importance of characterizing the vehicular emissions of the national fleet. In this paper, a first approach for this characterization is presented. It was carried out on a sample of 11 light vehicles currently in use in Montevideo city, Uruguay. On-road emissions measurements of nitrogen monoxide (NO), carbon monoxide (CO) and carbon dioxide (CO 2 ) were carried out for calculating the emission factors. The fitness of the set of calculated emission factors values to different probability distributions was tested. When possible, the 95% confidence intervals were obtained for the mean emission factors (CO: 2.0g/km±0.3g/km; NO: 0.05g/km±0.01g/km). This procedure was useful to obtaining accurate confidence intervals from a relatively small sample size. Finally, the link between atmospheric emissions and some other parameters of the tested vehicles was studied using a multivariate statistical tool, highlighting the strong increase in carbon monoxide emissions observed for low vehicles speeds and fuel efficiencies.

    Full Text Available Depuis un certain temps, les discussions sur les passés récents et violents, connus lors des années 1960-1980, sont l’un des enjeux majeurs des espaces publics dans plusieurs pays de l’Amérique du Sud. L’Uruguay, ayant vécu un régime civique militaire fortement répressif entre 1973 et 1985, n’a pas été l’exception. Pourtant, bien que les mémoires publiques sur ce passé aient traversé différentes périodes, c’est la disparition des personnes qui conduit presque toute l’histoire des luttes autour de la mémoire du pays. Dans ce texte, nous nous attelons à tracer l’histoire de la mémoire des disparus politiques dans l’arène publique en Uruguay pour connaître les motifs qu’ont faits des disparus de l’image du passé récent.Discussions on violence during the years 1960-1980 in South America have for some time been a central issue in the public space of many South American countries. Uruguay, having gone through a strongly repressive civic-military regime between 1973 and 1985, was no exception. While public memories on this period have gone through different phases, the forced disappearances have always been the main focus of the struggles for memory. This article attempts to trace the history of the remembering of these victims of forced disappearance in the Uruguayan public arena in order to determine memory patterns in the image of a recent past.

    This study analyzes prenatal care and birthweight in Uruguay. These data are unique since they represent a population of urban, poor women who gave birth in a health care system that provides both prenatal and obstetric care free of charge. This study finds a positive effect of increased prenatal care use on birthweight and evidence of bias in OLS estimates, similar to studies that use US data. The results highlight the usefulness of existing methodologies for estimating the effect of prenatal care on birthweight and the importance of extending these methodologies to data from countries other than the US.

    We exploit a natural experiment in Montevideo, Uruguay, in order to analyse the effects on human health of granting formal property rights to untitled individuals. Because of administrative mistakes committed decades ago by an institution that no longer exists, such rights may be transferred to residents of some neighborhoods but not to residents of others. We found that titling reduces the probability of suffering from hypertension and diabetes and in some cases rheumatism and asthma as well within 17 years of being offered property rights, but we did not find statistically significant evidence that the housing quality functions as a channel between titling and health. 2010 Elsevier B.V.

    2005-09-01

    The 2004 visual inspection of four Uruguay nuclear fuel assemblies stored in L-Basin was completed. This was the third inspection of this wet stored fuel since its arrival in the summer of 1998. Visual inspection photographs of the fuel from the previous and the recent inspections were compared and no evidence of significant corrosion was found on the individual fuel plate photographs. Fuel plates that showed areas of pitting in the cladding during the original receipt inspection were also identified during the 2004 inspection. However, a few pits were found on the non-fuel aluminum clamping plates that were not visible during the original and 2001 inspections.

    1998-01-01

    In the present work there are analyzed 16 samples of shales belonging to Castellanos and Migues formations (Cretaceous), taken from cores of various boreholes of the Santa Lucia Basin (Uruguay). Chemical analysis of major elements, trace elements (B,V, Sr, Rb, Cr y Ga) and X- ray diffractometry were done to them in order to obtain a geochemical characterization. The characterization shows that their chemical composition is comparable to the world average composition of shales. Besides, the X-ray diffractometry. Based on that, it is clear to deduce that it existed a change in the environment conditions having a shift from a redactor environment which agrees with former micropaleontologic studies. (author)

    Petrographic and geochemical features of porphyroblastic hornblendites in Piedra Alta Terrene of Uruguay are described. Their spatial and genetic relationships whith hornblendic gabbros and other basic plutonic rocks is also stablished. Their association with low grade metamorphic supracrustals inmagmatic mingling structures and late development, suggests an origin related to high vapour pressure that take off stability to gabbro paragenesis and favours Deer's reaction:pyroxene+ plagioclase +water= hornblende + SIO2. The silica produced is expressed as quartz dikes frequently mineralized with gold and platinum group elements. San Carlos gabbro is an uruguayan exemple of such proposed model.

    This work is about the paleorelief baseboard study by electrical soundings in the anomaly of Magnolia - Tacuarembo - Uruguay. But not all electrical soundings allowed a good prevision of coating thickness.The difficulties found in the determination of the depth of the electrical resistant baseboard are explained by discontinuities levels and lateral variations in resistivities. Moreover, the re modeling of the results according to the data of drilling led to a relatively coherent interpretation that provides a basis for all future intervention in the same type of formation
