Direction of movement of late paleozoic glaciers in Angola (Western Africa)

A identificação de um pavimento de clastos intercalado entre dois diamictitos da "Série de Lutôe", Angola, constitue evidência de origem glacial dessas rochas. A orientação de estrias sobre os clastos, a disposição espacial destes no pavimento, e a orientação de clastos de diamictitos indicam que as geleiras neopaleozóicas deslocaram-se de SE-NW nesta parte da Bacia do Congo.Identification of a boulder pavement intercalated between two diamictites of the "Lutôe Series" in Angola points out for a glacial origin for these rocks. Measurement of striae on clasts, their disposition in the pavement and the fabric of diamictites indicate movement of Late Paleozoic (Gondwana) glaciers towards NW in this part of the Congo Basin

Heavy metals and micronutrients in soils under dairy grazing right on top of the river Paranaíba basin in the state of Goiás, Brazil

In Brazil, the agricultural activity is among the most competitive sectors of national economy, in which milk production has a very significant contribution. Concern about environmental contamination by this activity is related to the fact that dairy cattle manure heavy metals present in the constitution; the creation of such animals in the grazing system directly questions the possibility of any contamination by these metals in the watery, area where these animals congregate at certain times of day for drinking water and where they defecate. This study aimed to evaluate the content of copper, iron, manganese, zinc, cadmium, lead and chromium in watery areas and in conservation areas (control) of 28 properties, grouped into six “otto-basins” forming the upper basin of the Paranaíba River in the State of Goiás. The simple soil samples were collected at three depths (0-10, 10-20 and 20-30 cm) obtained from such a composite sample for each depth in the areas watered and preserved. The analysis of PCA metals pollutants in soils watery areas analyzed did not indicate the occurrence of contamination in these environments when compared to the preserved area. Observed random distribution of average levels of metals in the three studied depths in all treatments, which complicates the definition of the potential for soil contamination by feces of dairy farming originated in watery areas, under rotational grazing.A preocupação quanto à contaminação do ambiente por meio da atividade leiteira está relacionada ao fato dos dejetos destes bovinos apresentarem metais poluentes em sua constituição; na criação desses animais no sistema de pastejo direto questiona-se a possibilidade da ocorrência de contaminação por estes metais nas aguadas, área onde esses animais se aglomeram em determinados períodos do dia para beberem água e onde defecam. O presente estudo objetivou avaliar os teores dos metais cobre, ferro, manganês, zinco, cádmio, chumbo e cromo em áreas de aguadas e em áreas preservadas (testemunha) de 28 propriedades, agrupadas em seis Ottobacias hidrográficas formadoras do alto da bacia do Rio Paranaíba, no Estado de Goiás. As amostras simples de solos foram coletadas em três profundidades (0-10, 10-20 e 20-30 cm), a partir destas foram obtidas uma amostra composta para cada profundidade nas áreas de aguadas e preservadas. Pela análise de PCA os metais poluentes analisados nos solos de aguada não indicou a ocorrência de contaminação nestes ambientes quando comparados à área preservada. A distribuição aleatória dos teores médios dos metais nas três profundidades estudadas em todos os tratamentos dificulta a definição do potencial de contaminação do solo pelos dejetos originados da atividade leiteira em áreas de aguadas, sob pastejo direto3052582590Alvarenga, M.I.N., Davide, A.C., Características físicas e químicas de um Latossolo Vermelho-Escuro e a sustentabilidade de agroecossistemas (1999) Revista Brasileira de Ciência do Solo, 23 (4), pp. 933-942. , ViçosaByers, H.L., Cabrera, M.L., Matthews, M., Franklin, D.H., Andrae, J.G., Radcliffe, D.E., McCann, M.A., Calvert Jr, V.H., Phosphorus, sediment and Escherichia coli loads in unfenced streams of the Georgia Piedmont, USA (2005) Journal of Environmental Quality, 34 (11), pp. 2293-2300. , MadisonCorreia, P.R.M., Ferreira, M.M.C., Reconhecimento de padrões por métodos não supervisionados: Explorando procedimentos quimiométricos para o tratamento de dados analíticos (2007) Revista Química Nova, 30 (2), pp. 48-487. , São PauloEMBRAPA-Embrapa Informação Tecnológica, (2003) Pesquisa, desenvolvimento e inovação para o agronegócio brasileiro: Cenários 2002-2012, 92p. , Embrapa/Secretaria de Gestão e Estratégia.

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.
