The Early Paleozoic geodynamic evolution in SW Iberia is believed to have been dominated by the opening of the Rheic Ocean. The Rheic Ocean is generally accepted to have resulted from the drift of peri-Gondwanan terranes such as Avalonia from the northern margin of Gondwana during Late Cambrian-Early Ordovician times. The closure of the Rheic Ocean was the final result of a continent-continent collision between Gondwana and Laurussia that produced the Variscan orogen. The Ossa-Morena Zone is a peri-Gondwana terrane, which preserves spread fragments of ophiolites - the Internal Ossa-Morena Zones Ophiolite Sequences (IOMZOS). The final patchwork of the IOMZOS shows a complete oceanic lithospheric sequence with geochemical characteristics similar to the ocean-floor basalts, without any orogenic fingerprint and/or crustal contamination. The IOMZOS were obducted and imbricated with high pressure lithologies. Based on structural, petrological and whole-rock geochemical data, the authors argue that the IOMZOS represent fragments of the oceanic lithosphere from the Rheic Ocean. Zircon SHRIMP U-Pb geochronological data on metagabbros point to an age of ca. 480 Ma for IOMZOS, providing evidence of a well-developed ocean in SW Iberia during this period...

Technical evaluation of analytical data is of extreme relevance considering it can be used for comparisons with environmental quality standards and decision-making as related to the management of disposal of dredged sediments and the evaluation of salt and brackish water quality in accordance with CONAMA 357/05 Resolution. It is, therefore, essential that the project manager discusses the environmental agency`s technical requirements with the laboratory contracted for the follow-up of the analysis underway and even with a view to possible re-analysis when anomalous data are identified. The main technical requirements are: (1) method quantitation limits (QLs) should fall below environmental standards; (2) analyses should be carried out in laboratories whose analytical scope is accredited by the National Institute of Metrology (INMETRO) or qualified or accepted by a licensing agency; (3) chain of custody should be provided in order to ensure sample traceability; (4) control charts should be provided to prove method performance; (5) certified reference material analysis or, if that is not available, matrix spike analysis, should be undertaken and (6) chromatograms should be included in the analytical report. Within this context and with a view to helping environmental managers in analytical report evaluation...

The existence of allergenic activity in the atmosphere is not only associated to pollen grains and fungal spores, but also to submicronic and paucimicronic biological particles. The origin of these allergens can be due to the rupture of pollen transported in the atmosphere or to the presence of allergens from other parts of the plant making amorphous material with allergenic load. Poaceae pollen is recognized as one of the main causes of allergic disease in all Europe. In this study we have tried to compare Poaceae pollen counts in the air and Phl p 5...

Between 7.5 kyr and 4 kyr a fluvial limestone tuffs system developed in the south-western corner of Iberia. This system is characterised by a segmented up to 60 meters thick limestone sequence dated by radiocarbon. The system is calcite dominated, and the other coeval mineral constituents comprise iron oxides and hydroxides and clay minerals. Other mineralogical components such as quartz and feldspar are seldom and detrital, from the surrounding Upper Carboniferous and Upper Triassic formations. Most of the tuffs are well banded, with a layering which ranges in thickness from the micrometric scale to the centimetric scale. The different centimetric layers were sampled and bulk δ18O, δ13C and 87Sr/86Sr were determined. The oxygen and carbon isotopes were used as recognized proxies for paleoenvironmental conditions and the Sr isotopes with the purpose of understanding the residence time of the meteoric waters in the surrounding carbonate formations. The main results point to: (i) the hydrologic conditions of the system were not suitable for the waters from which the limestone tuffs precipitated to equilibrate with the Mesozoic carbonate formations; (ii) the probability of having old carbon in those waters is very low increasing the reliability of the 14C age determinations; (iii) the composition in stable isotopes of the waters were probably close to the meteoric water composition for the period under consideration; (iv) between 7.5 kyr and 4 kyr the oxygen isotopic composition of the limestone tuffs show a gradual depletion in 16O with the values of δ18O increasing from -5 to -3.5 probably related to an increase in the importance of the evaporation in the hydrological system; (v) during the same time interval the 13C composition of the limestone tuffs remains crudely constant reflecting the stability of the vegetation cover.

The Cape Saint Vincent (SW Iberia) region is of major seismological interest for its tectonic complexity and for the occurrence of the great 1755 Lisbon earthquake that affected the Iberian Peninsula and produced extensive damage generating a large tsunami too. We here examine the mechanism of the three largest earthquakes to have occurred in the last 40 years west of the Cape – 29 July 2003 (Mw=5,3), 12 February 2007 (Mw=6,1), and 17 December 2009 (Mw=5,5). By inversion of the teleseismic body waves we estimated the three earthquakes show NE-SW rupture planes, with horizontal pressure axis compatible with the regional NW-SE horizontal compression produced by the convergence of the Eurasian and African plates. Applied to the generation of the 1755 Lisbon earthquake, this direction of faulting would correspond to a complex rupture along NE-SW trending faults presents in the region.

O gene Sw-5 do tomateiro confere resistência a várias espécies de tospovírus e codifica uma proteína contendo domínios de ligação a nucleotídeos e repetições ricas em leucina. Tomateiros com Sw-5 exibem reações necróticas nas folhas inoculadas com tospovírus. Estas reações e a estrutura da proteína Sw-5 indicam que a resistência ocorre por meio do reconhecimento do patógeno e desencadeamento da resposta de hipersensibilidade. A capacidade de Sw-5 de conferir resistência a tospovírus em tabaco selvagem (Nicotiana benthamiana Domin.) foi avaliada em plantas transgênicas. Uma construção com a seqüência aberta de leitura de Sw-5 e sua região 3’ não-traduzida sob controle do promotor 35S do CaMV foi utilizada para transformação de N. benthamiana via Agrobacterium tumefaciens. Plantas de progênies R1 foram inoculadas com um isolado de tospovírus e avaliadas quanto à ocorrência de reação de hipersensibilidade e resistência à infecção sistêmica. Em uma progênie com segregação 3:1 (resistente:suscetível), foi selecionada uma planta homozigota e sua progênie avaliada quanto ao espectro da resistência a tospovírus. Plantas com o transgene exibiram resposta de hipersensibilidade 48 h após a inoculação...

An important issue in software development is to reduce the time required to obtain the final systems that meets the organization requirements. A practice to be considered, which can change dramatically the time and costs required to develop, is software components reuse. In addition, reuse can increase the development productivity and improve the product quality. The main objective of this work is to add new process areas to the maturity model CMMI-SE/SW, once that doesn’t cover software components reuse. The new process areas have preserved the original content of the ISO/IEC 15504-5, which standardizes well the reuse good practices, allowing their adoption by organizations that develop software based on the CMMI-SE/SW. To generalize the CMMI-SE/SW model, the following aggregated process areas are proposed: Asset Management, Reuse Program Management and Domain Engineering.

Tomato is one of the most cultivated vegetables worldwide, and this is an important factor in their vulnerability to attack by pests and diseases, which contribute to the decrease in production and affects the quality of the fruit. Among diseases affecting tomato production, the ones caused by viruses are of the utmost importance, which are more difficult to control, highlighting those caused by species of the genus Tospovirus, which can cause losses of up to 100 %. The tospoviruses are responsible for the disease known as 'tomato spotted wilt' and are transmitted by thrips. In Brazil, four species of tospoviruses occur in tomato: Tomato spotted wilt virus (TSWV), Tomato chlorotic spot virus (TCSV), Groundnut ringspot virus (GRSV) and Chrysanthemum stem necrosis virus (CSNV), with a greater incidence of GRSV. The first TSWV resistance gene identified was the Sw-5, which is effective against all species of tospoviruses infecting tomato and is widely used in breeding programs for this reason, because the resistance gene presents a dominant trait. Sources of resistance were found in other wild accessions of the species S. chilense, S. habrochaites, S. pimpinellifolium, S. corneliomuelleri and S. lycopersicum, showing promising results as sources of resistance for use in breeding programs. To identify a source of tospovirus resistance in wild accessions of the Germplasm Bank of Embrapa Hortaliças...

The SCAR (Sequence Characterized Amplified Region) 'Sw-421' molecular marker is located at 1.0 cM from the Sw-5 allele, originated from Lycopersicon peruvianum (L.), which confers resistance to the tomato spotted wilt virus (TSWV). However, it had not been tested yet in advanced tomato populations. The goal of this study was to distinguish resistant homozygotes (Sw-5/Sw-5) and heterozygotes (Sw-5/Sw-5+) from susceptible (Sw-5+/Sw-5+) plants in crossing populations with the Stevens cultivar and advanced backcrossing populations by using 'Sw421' SCAR marker. The amplification of 940 bp and 900 bp bands characterized the resistant homozygotes and susceptible controls, respectively. A two band pattern (900 bp and 940 bp) was observed in heterozygote genotypes (Sw-5/Sw-5+), which confirmed the co-dominant inheritance mechanism of the marker. Fifty seven plants from the isogenic progenies were characterized based on bands pattern: 18 plants (31.6%) were identified as resistant homozygotes, 8 plants (14.0%) as resistant heterozygotes and 31 plants (54.4%) were characterized as susceptible. The SCAR 'Sw-421' marker is an important tool for selection and pyramid resistance alleles, mainly when other resistance sources to the TSWV are available...

Benthic foraminifera from twenty stations sampled twice were analyzed in order to examine the environmental conditions of the Albufeira coastal lagoon. Foraminiferal assemblages show an increase in the abundance, species diversity and allochthonous content seaward. Three zones have been defined: the inner and more restricted area of the lagoon where the main species are the euryhaline Ammonia tepida and Haynesina germanica; these two species together with Bulimina gibba and Brizalina britannica dominated the middle area; and, finally, in the mouth and marine- influenced back-barrier area the assemblages are made up of brackish and marine species such as A. tepida, Cribroelphidium williamsoni, Cibicides lobatulus and H. germanica. Additionally, samples from three cores were also examined. Sedimentological and micropalaeontological contents represent the last 2500 years of environmental evolution of the lagoon. Foraminiferal assemblages are not very abundant and they are dominated by H. germanica, A. tepida and Jadammina macrescens indicating very restricted conditions through time. In a regional context, and during the Late Holocene, after the development of a detrital barrier circa 5.5 cal yr BP, eustasy is considered to be a minor environmental control of the barrier-lagoonal system dynamics.

v. 45, n. 3, p. 340-347, jul./set. 2015.; The intensive and uninterrupted tomato cultivation has favored the establishment of several diseases that affect fruit yield and quality. Genetic resistance is the best method to control the disease called ‘vira-cabeça’ (caused by distinct species of the genus Tospovirus), being Sw-5 the first resistance gene effectively identified to control it in tomato plants. This study aimed at identifying new potential sources of tospovirus resistance in wild Solanum (Lycopersicon) species, as well as performing phylogenetic analysis related to the evolutionary characteristics of the Sw-5b gene, in accessions of wild tomato species. These analyses showed that the different tomato species belong to distinct evolutionary groups. Most of the accessions with wide-spectrum resistance to Tospovirus species correspond to allelic variants closely related to the original Sw-5b gene copy. However, resistant accessions of S. chilense and S. habrochaites are located in distinct phylogenetic groups, meaning that they may represent promising sources of new genes/alleles, providing wide resistance to tospovirus.; Programa de Apoio à Publicações Periódicas Científicas (PROAPUPEC) da UFG;CNPq; CAPES; O cultivo ininterrupto e intensivo de tomateiro tem favorecido o estabelecimento de diversas doenças que afetam a produção e a qualidade dos frutos.

Protein isolate was prepared from defatted seed of mesquite beans (Porsopis juliflora (SW) D.C.) by alkaline extraction (pH10) and precipitation with hydrochloric acid. In the extraction of proteins from initial samples, 75,0% was extracted and 62.3% was recovered through precipitation. Functional characteristics of protein isolate was studied in terms of terms of solubility water and fat absorption, emulsifying and foaming properties. Protein isolate presented high solubility at acidic and basic pH, except in the pH range between 4 and 6. the water and fat. absorption was possibly influenced by the compact structure of the isolate. The emulsifying capacity was higher at pH 3 and lower at 5. The emulsifying capacity and emulsion stability presented small variations, except at pH 5. The foaming properties depended directly on solubility of proteins. The presence of sodium chloride improved the protein solubility, emulsifying capacity and foaming properties at pH5.; O isolado protéico foi obtido da farinha desengordurada de semente de algaroba (Porsopis juliflora (SW) D.C.) por meio da extração alcalina (pH 10) e posterior precipitação com ácido clorídrico a pH 5.

The petrographic, heavy mineral analyses and geochemical results from the Nama Group indicate a recycled upper crust composition characterized mainly by metamorphic and granitic and minor mafic rocks sources. Paleocurrent analyses of the chromian spinel bearing sandstones of the Nama Basin point to a volcanic island arc source located in the Damara Belt. Detrital zircon dating of the Nama Group display major peaks of Neoproterozoic and Mesoproterozoic ages suggesting a provenance from the Damara/Gariep Belts and their basements. Paleocurrents from the west and the dominance of Neoproterozoic-Cambrian detrital U-Pb zircon ages (76%) in the "Molasse" stage of the foreland evolution probably indicate exhumation of the felsic volcanic arc root which probably occurred after the time indicated by the younger zircon dated at 531 ±9 Ma. The petrographic and geochemical results from the Arroyo del Soldado Group indicate a recycled upper crust composition characterized by source diversity composed of granite-gneissic and mafic-metamorphic rocks. On average, Nd isotopes account for negative eNd values and T DM ages in a range of variation found elsewhere within SW Gondwana. Detrital U-Pb zircon dating indicate sources dominated by Paleoproterozoic (1.7-2.0-2.2 Ga) and subordinate Archaean ages (2.5-2.9-3.5 Ga). The scarcity of Mesoproterozoic and Neoproterozoic zircons and paleocurrent directions towards the east indicate that the Arroyo del Soldado Group was fed by detritus from the Río de la Plata Craton favouring a passive margin tectonic setting for their deposition. Deformation of the Arroyo del Soldado Group took place ca. 530 Ma...

El presente estudio proporciona información del crecimiento de Brosimum alicastrum (ramón) durante sus primeros años, en una plantación comercial localizada en Yucatán, México. Las plantas fueron desarrolladas a partir de semillas y cultivadas en vivero hasta la edad de un año de edad y 65 cm de altura, momento en el cual fueron transportadas al campo en donde se plantaron a una distancia de 5 m entre ellas. Los trasplantes se realizaron en los años 2006, 2007 y 2009 y las mediciones se hicieron del 2010 al 2012, cuando contaban con 2, 4 y 5 años de edad. Se eligieron 10 árboles de cada edad, y durante 24 meses se midió la altura máxima y el diámetro del tallo a 50 cm del suelo. Se determinó que las plántulas desarrolladas en vivero, en los primeros seis meses, crecen en forma lineal a una tasa de 0.65 m año-1, posteriormente, en condiciones de campo hasta los 7 años, el crecimiento fue exponencial. La fase de endurecimiento inicia a los 6 años, con un incremento en el diámetro del tallo superior al doble. Durante la época de lluvias se registraron 65 y 69 % del crecimiento en diámetro y altura respectivamente, comparado con el crecimiento en la época de sequía. Las edades de los árboles considerados en este trabajo se consignan como primera etapa de crecimiento...
