    The Spanish Instituto Nacional de Técnica Aeroespacial has a network of three telescopes located at some of the best places for astronomy in mainland Spain. The first is at the Observatorio de Calar Alto in Almeria, at an altitude of more than 2100 m. The second is near Calatayud in Zaragoza, at the summit of a 1400-m high mountain. The last is on the campus of the Instituto Nacional de Técnica Aerospatial (INTA), in Madrid. The three telescopes are either 40 or 50 cm in diameter and will be available for communications and educational projects.

    A development history and performance capability assessment is presented for the INTA-300 'Flamenco' sounding rocket prototype specimens. The Flamenco is a two-stage solid fuel rocket, based on British sounding rocket technology, that can lift 50 km payloads to altitudes of about 300 km. The flight of the first two prototypes, in 1974 and 1975, pointed to vibration problems which reduced the achievable apogee, and the third prototype's flight was marred by a premature detonation that destroyed the rocket. The fourth Flamenco flight, however, yielded much reliable data.

    2011-02-01

    Comparative genome analysis of Enterococcus faecium recently revealed that a genomic island containing the esp gene, referred to as the esp-containing pathogenicity island (esp PAI), can be transferred by conjugation and contains a partial Tn916-like element and an integrase gene, intA. Here, we characterize the role of intA in the excision of the esp PAI. An intA insertion-deletion mutant in E. faecium E1162 (E1162ΔintA) was constructed and in trans complemented with wild-type intA (E1162ΔintA::pEF30). Circular intermediates (CI) of excised esp PAI were determined using inverse PCR analysis on purified chromosomal DNA from strains E1162, E1162Δesp, E1162ΔintA, and E1162ΔintA::pEF30. In E1162 and E1162Δesp, CI of the esp PAI were detected. No CI were detected in E1162ΔintA, while in the complemented strain E1162ΔintA::pEF30 CI formation was restored, indicating that intA is essential for excision and subsequent mobilization of the esp-containing genomic island in E. faecium. Based on the fact that this island can be mobilized and is self-transmissible, we propose to change the name of the esp PAI to ICEEfm1.

    Full Text Available A retrospective study was performed on 169 beef and dairy calves aged from 1 to 7 days old submitted to the Diagnostic Laboratories at INTA Balcarce, Argentina. Bacterial culture was performed for aerobic and microaerophilic organisms. Samples from spleen and lymph nodes, and peripheral blood mononuclear cells were also cultured for viral isolation on cell culture. Bovine rotavirus was detected by direct-ELISA. Multiple tissue samples were fixed in 10% formalin, routinely processed and stained with hematoxylin and eosin for microscopic examination. Etiological diagnosis was made in 70 of the 169 calves. Infectious agents were identified in 49 cases, the most common being Escherichia coli. When the histopathological examination was performed in cases with undetermined diagnosis, it was noted that 44 specimens had histological lesions, which suggested the presence of an infectious agent. In order to characterize the causes of bovine neonatal mortality, the protocols and methodology should be improved in further works.Se realizó un estudio restrospectivo en 169 terneros muertos 1 a 7 días después del nacimiento pertenecientes a rodeos para carne y leche, remitidos a los Laboratorios de Diagnóstico del INTA Balcarce, Argentina.

    Full Text Available In searching for new cultivars that are better adapted to edapho-climatic constraints existing in northwestern Argentina, mainly drought and salinity stress, a hybrid of buffelgrass (Cenchrus ciliaris L. named Lucero INTA PEMAN was obtained by controlled crosses at the Instituto de Fitopatología y Fisiología Vegetal, INTA. The objective was to morphologically evaluate and compare Cenchrus ciliaris cv Lucero with Texas-4464, Biloela and Molopo cultivars in Dean Funes (North of the Province of Córdoba, Argentina under drought field conditions using a randomized complete block design with three replications in two crop cycles (2006/2007 and 2007/2008 considering one-year plant and re-growth as ontogenic stages of the plant, respectively. Thirteen morphological characters were analyzed by ANOVA and DGC testing (p <0.05. Although most of the thirteen morphological characters evaluated showed decreased re-growth over one-year plants, Lucero was least affected by low water availability, showed highest values for seed production components in both ontogenic stages and was superior to Texas-4464 in biomass production characters and to Biloela and Molopo cultivars in most of them. Lucero showed a promising and considerable forage value for drought-affected regions, such as northwestern Argentina.

    Full Text Available Understanding the population structure and genetic diversity in sugarcane (Saccharum officinarum L. accessions from INTA germplasm bank (Argentina will be of great importance for germplasm collection and breeding improvement as it will identify diverse parental combinations to create segregating progenies with maximum genetic variability for further selection. A Bayesian approach, ordination methods (PCoA, Principal Coordinate Analysis and clustering analysis (UPGMA, Unweighted Pair Group Method with Arithmetic Mean were applied to this purpose. Sixty three INTA sugarcane hybrids were genotyped for 107 Simple Sequence Repeat (SSR and 136 Amplified Fragment Length Polymorphism (AFLP loci. Given the low probability values found with AFLP for individual assignment (4.7%, microsatellites seemed to perform better (54% for STRUCTURE analysis that revealed the germplasm to exist in five optimum groups with partly corresponding to their origin. However clusters shown high degree of admixture, F ST values confirmed the existence of differences among groups. Dissimilarity coefficients ranged from 0.079 to 0.651. PCoA separated sugarcane in groups that did not agree with those identified by STRUCTURE. The clustering including all genotypes neither showed resemblance to populations find by STRUCTURE, but clustering performed considering only individuals displaying a proportional membership > 0.6 in their primary population obtained with STRUCTURE showed close similarities. The Bayesian method indubitably brought more information on cultivar origins than classical PCoA and hierarchical clustering method.

    Common bean (Phaseolus vulgaris L.) is an important legume with high nutritional value. In Nicaragua, certified healthy seeds of local bean varieties are not available, and seedborne fungi have gained little attention. Here, were surveyed seedborne pathogenic fungi in an important local bean cultivar, 'INTA Rojo'. Beans grown in the four main production areas in Nicaragua (Boaco, Carazo, Estelí, Matagalpa) for future use as seed stock were sampled from four seed storehouses and six seed lots. A total of 133 fungal strains were isolated from surface-sterilized beans and inoculated to healthy lima beans (Phaseolus lunatus) under controlled conditions. Eighty-seven isolates caused symptoms of varying severity in the seedlings, including discoloration, necrotic lesions, cankers, rot, and lethal necrosis. Pathogenic isolates were divided into eight phenotypically distinguishable groups based on morphology and growth characteristics on artificial growth medium, and further identified by analysis of the internal transcribed spacer sequences (ITS1 and ITS2) of the ribosomal RNA genes. The pathogenic isolates belonged to eight genera. Fusarium spp. (F. chlamydosporum, F. equiseti, F. incarnatum), Lasiodiplodia theobromae, Macrophomina phaseolina, and Penicillium citrinum were the most damaging and common fungi found in the seed lots. Furthermore, Corynespora cassiicola, Colletotrichum capsisi, Colletotrichum gloeosporioides, Aspergillus flavus, and Diaporthe sp. (Phomopsis) were seedborne in cultivar 'INTA Rojo' and found to be pathogenic to bean seedlings. This study reveals, for the first time, many seedborne pathogenic fungi in beans in Nicaragua; furthermore, prior to this study, little information was available concerning F. equiseti, F. incarnatum, L. theobromae, C. cassiicola, and Diaporthe spp. as seedborne pathogens of common bean. Our results lay the basis for developing diagnostic tools for seed health inspection and for further study of the epidemiology

    Full Text Available The Department of Earth Sciences of University of Florence has conducted over the past ten years, numerous studies about the distribution of arsenic and heavy metals in mineralized areas of Tuscany, particularly in the Pecora basin. The area hosts several polymetallic ore bodies and a pyrite ore deposit. The studies have identified several geochemical anomalies (As, Cu, Pb, Zn… both in the areas which host the ore bodies and in the coastal plain (Scarlino Plain. To increase the knowledge concerning the distribution of As and heavy metals in other Tuscan coastal plains, research is under way in the alluvial plains of the Bruna, Cornia and Alma rivers. The preliminary analysis have focused on soils and stream sediments, to better understand the correlations between the downstream transport of rivers and the soils. We have made physic-chemical analysis, particle size analysis, mineralogical analysis for X-ray powder diffraction, chemical analysis for the determination of major element (X-ray Fluorescence and for the determination of 35 minor elements and traces (AAS and ICP.Preliminary data show high concentrations of several elements (As, Zn, Co…. The concentrations of these elements in soils and stream bed sediments are not always consistent; in particular we have found higher concentrations in soils than in stream bed sediments in Cornia Plain, while the opposite happens in the Bruna basin. Therefore the natural processes of rocks weathering does not seem to have affected uniformly. The distribution of As and heavy metals in soils and stream bed sediments of the all three basins of interest are still under investigation.

  17. Parametric bootstrap for testing model fitting in the proportional hazards framework: an application to the survival analysis of Bruna dels Pirineus beef calves.

    Given that correct assumptions on the baseline survival function are determinant for the validity of further inferences, specific tools to test the fit of a model to real data become essential in proportional hazards models. In this sense, we have proposed a parametric bootstrap to test the fit of survival models. Monte Carlo simulations are used to generate new data sets from the estimates obtained through the assumed models, and then bootstrap intervals can be established for the survival function along the time space studied. Significant fitting deficiencies are revealed when the real survival function is not included within the bootstrap interval. We tested this procedure in a survival data set of Bruna dels Pirineus beef calves, assuming 4 parametric models (exponential, Weibull, exponential time-dependent, Weibull time-dependent) and the Cox's semiparametric model. Fitting deficiencies were not observed for the Cox's model and the exponential time-dependent model, whereas the Weibull time-dependent model suffered from moderate overestimation at different ages. Thus, the exponential time-dependent model appears to be preferable because of its correct fit for survival data of beef calves and its smaller computational and time requirements. Exponential and Weibull models were completely rejected due to the continuous over- and underestimation of the survival probability reported. Results here highlighted the flexibility of parametric models with time-dependent effects, achieving a fit comparable to nonparametric models.

    During the last two years the INTA -- National Institute for Aerospace Technique -- library has been improving different areas related to the information management processes, such as those related to cataloguing, dissemination of technical information, centralization at the Library of all relevant documents and information applicable to scientific research within our organization, implementation of library web services, etc. As part of these processes of modernization of services that the INTA Library is carrying out, a project of digitization of both technical documentation and historical records of the Institute has been defined. The goal is to achieve the total digitization of technical documents and historical papers through the year 2006, and provide access for the resulting electronic collection to the Spanish aerospace community. For the development of the project a deep study of the state of the art in digitization and preservation matters has been conducted. That study covers the different aspects of such a project that could be experienced, such as the risk of data loss, the bandwidth needed to guarantee access to this huge quantity of electronic documentation, the fragility of the digital media, the rapid obsolescence of hardware and software, etc. Also the project is going to assume the new reality of documents that are not originating in paper format, but are digital-born, and how to integrate all the electronic documents in one system, fulfilling the same standards and using the same available technology.

Trata-se de publicação que gerou enorme controvérsia. Hume afirma, em carta de 10 de março de 1751 a Sir Gilbert Elliot, que faz de Cleantes “o herói” da história. Ainda, em outra correspondência, remetida em 8 de junho de 1776 a William Strahan, seu editor, Hume pretende convencê-lo a publicar os Diálogos, não sem apresentar a ressalva de que, ainda que o cético seja silenciado ao final, a obra apresenta, antes disso, tópicos que poderiam gerar comoção.

    Bacillus thuringiensis INTA 7-3, INTA 51-3, INTA Mo9-5 and INTA Mo14-4 strains were obtained from Argentina and characterized by determination of serotype, toxicity, plasmid composition, insecticidal gene content ( cry and vip ) and the cloning of the single- vip3A gene of the INTA Mo9-5 strain. The serotype analysis identified the serovars tohokuensis and darmstadiensis for the INTA 51-3 and INTA Mo14-4 strains, respectively, whereas the INTA Mo9-5 strain was classified as "autoagglutinated". In contrast to the plasmid patterns of INTA 7-3, INTA 51-3 and INTA Mo9-5 (which were similar to B. thuringiensis HD-1 strain), strain INTA Mo14-4 showed a unique plasmid array. PCR analysis of the four strains revealed the presence of cry genes and vip3A genes. Interestingly, it was found that B. thuringiensis 4Q7 strain, which is a plasmid cured strain, contained vip3A genes indicating the presence of these insecticidal genes in the chromosome. Bioassays towards various lepidopteran species revealed that B. thuringiensis INTA Mo9-5 and INTA 7-3 strains were highly active. In particular, the mean LC(50) obtained against A. gemmatalis larvae with the INTA Mo9-5 and INTA 7-3 strains were 7 (5.7-8.6) and 6.7 (5.6-8.0) ppm, respectively. The INTA Mo14-4 strain was non-toxic and strain INTA 51-3 showed only a weak larvicidal activity.

    Single crystals of PbIn 1/2Nb 1/2O 3 (PIN), PbIn 1/2Ta 1/2O 3 (PIT), PbYb 1/2Nb 1/2O 3 (PYN), PbYb 1/2Ta 1/2O 3 (PYT) and PbMg 1/2W 1/2O 3 (PMW) have been grown by the flux method. The PbO-based solvents were used. Transparent, light yellow and arrow like shaped PIN and PIT crystals of the perovskite structure were obtained. Small amounts of red and of octahedron habit PIN and PIT crystals of the pyrochlore type were simultaneously grown. In the case of PYN, PYT and PMW only the crystals of the perovskite structure have been grown. The transparent and brown PYN and PYT crystals of octahedron habit were obtained. The transparent, light yellow and of octahedron or truncated octahedron shape PMW crystals were grown. The crystals were characterised by X-ray and dielectric studies. They showed that as-grown PIN crystals are nearly disordered, exhibit the rhombohedral distortion of the pseudo-perovskite unit cell and reveal relaxor behaviour. The partially ordered PIT crystals show monoclinic distortion and undergo antiferroelectric-paraelectric phase transition. The PYN, PYT and PMW single crystals, characterised by chemical order in the B'/B″ ion sublattice, exhibit orthorhombic symmetry and undergo the first-order antiferroelectric-paraelectric phase transitions.

  1. Class-first analysis in a continuum: an approach to the complexities of schools, society, and insurgent science

    Science.gov (United States)

    Valdiviezo, Laura Alicia

    2010-06-01

    This essay addresses Katherine Richardson Bruna's paper: Mexican Immigrant Transnational Social Capital and Class Transformation: Examining the Role of Peer Mediation in Insurgent Science, through five main points . First, I offer a comparison between the traditional analysis of classism in Latin America and Richardson Bruna's call for a class-first analysis in the North American social sciences where there has been a tendency to obviate the specific examination of class relations and class issues. Secondly, I discuss that a class-first analysis solely cannot suffice to depict the complex dimensions in the relations of schools and society. Thus, I suggest a continuum in the class-first analysis. Third, I argue that social constructions surrounding issues of language, ethnicity, and gender necessarily intersect with issues of class and that, in fact, those other constructions offer compatible epistemologies that aid in representing the complexity of social and institutional practices in the capitalist society. Richardson Bruna's analysis of Augusto's interactions with his teacher and peers in the science class provides a fourth point of discussion in this essay. As a final point in my response I discuss Richardson Bruna's idea of making accessible class-first analysis knowledge to educators and especially to science teachers.

    INTA EMC Area has a wide experience in performing Radiated Susceptibility (RS) tests according to civilian, military and aeronautical standards in Mode Tuned Chambers (MTC) for national and international projects; besides, INTA has two Thermal Vacuum Chamber (TVC) facilities in service for Space Systems tests. In order to perform RS tests to Space Systems in a more realistic environment, INTA EMC Area has stablished an internal research program to develop a procedure to perform this kind of tests inside a TVC as a Mode Tuned Chamber (MTC). In this paper the results of the TVC-04 validation measurements as a MTC are presented.

  5. Troubling the proletarianization of Mexican immigrant students in an era of neoliberal immigration

    Science.gov (United States)

    Choudry, Aziz

    2010-06-01

    In response to Richardson Bruna's "Mexican immigrant transnational social capital and class transformation: examining the role of peer mediation in insurgent science", this paper draws on the author's research on organizing, mobilization and knowledge production among adult im/migrant workers in Canada. While appreciative of the content and concerns of Richardson Bruna's argument, the paper argues for a clearer position on tensions between agency and structure, and class and capitalist social relations in which to contextualize the schooling of immigrant children in today's US classrooms. In addition, it explores some implications of Mignolo's (2000) work on the geohistory of knowledge, notably his concept of `border thinking' for teachers, teacher education, and curricula. Finally, the article suggests the potential of methodological frameworks and approaches of institutional ethnography (Smith 1987), political activist ethnography (Frampton et al. 2006) and global ethnography (Burawoy 2000) to inform research into this field.

    Full Text Available In order to determine the effect of cultivars and planting date on flax fatty acid profile, seed yield, and oil content, an assay with seven cultivars (Baikal, Prointa Lucero, Prointa Ceibal, Panambí INTA, Curundú INTA, Carapé INTA, and Tape INTA was carried out at Parana Agricultural Experimental Station, Argentina. Significant differences among cultivars were found for content of palmitic (5–7 g/100 g, stearic (5–8 g/100 g, linoleic (13–19 g/100 g, saturated (11–15 g/100 g, and unsaturated acids (92–96 g/100 g within the seven cultivars. The best seed yields were observed in Prointa Lucero and Carapé INTA varieties (2091.50 kg·ha−1 and 2183.34 kg·ha−1, respectively in the first planting date and in Carapé INTA and Prointa Lucero (1667 kg·ha−1 and 1886 kg·ha−1, respectively in the second planting date. A delayed planting date had a negative effect on seed yield (1950 kg·ha−1 and 1516 kg·ha−1 and oil content (845 kg·ha−1 and 644 kg·ha−1 but did not affect oil composition.

  12. Scalar oscillatory integrals in smooth spaces of homogeneous type

    CERN Document Server

    Gressman, Philip T

    2012-01-01

    We consider a generalization of the notion of spaces of homogeneous type, inspired by recent work of Street [21] on the multi-parameter Carnot-Caratheodory geometry, which imbues such spaces with differentiability structure. The setting allows one to formulate estimates for scalar oscillatory integrals on these spaces which are uniform and respect the underlying geometry of both the space and the phase function. As a corollary we obtain a generalization of a theorem of Bruna, Nagel, and Wainger [1] on the asymptotic behavior of scalar oscillatory integrals with smooth, convex phase of finite type.

Animalswere slaughtered at an average age of 345 d. Carcass weight,conformation and fattening were evaluated. From these results the main carcass values in the label “Vedella dels Pirineus Catalans” areestablished. As it increases the carcass weight, no increase of the carcass conformation and fat grades is registered, and the carcass weight do no show a correlation with age. Based on effects, crosses had heavier carcass weights, but “Bruna dels Pirineus” showed more equilibrated values in the studied variables. A proposed aspect is the possibility to exclude crosses with “Bruna dels Pirineus” breed from the label I.G.P. “Vedella dels Pirineus Catalans” and to restrict the beef production to that pure breed.

    A new Instituto Nacional de Tecnica Aeroespacial (INTA) station, located about 70 km east of the Deep Space Network (DSN) Madrid complex (Robledo), is planned to support National Polar-orbiting Operational Environmental Satellite System (NPOESS) satellites. The 26.7-GHz NPOESS Ka-band downlink to this proposed station can potentially interfere with the DSN Madrid station that may support the future lunar and Sun-Earth Lagrange point missions operating in the 25.5- to 27.0-GHz band. A preliminary compatibility analysis has been conducted to assess the potential impact to the DSN Madrid complex from the NPOESS Ka-band downlink to the planned INTA station.

  5. Development of an electrical connector for liquid sodium environment. Final Report

    The INstrumented irradiation Test Assembly (INTA) has been used to conduct precision on-line instrumented irradiation tests in the experimental fast reactor JOYO. In INTA, direct instrumentation wiring between the irradiation test section in the core and the upper structure section in the rotating plug makes INTA structurally complex and expensive. Instead of direct wiring, if an electrical connector capable of withstanding a heated liquid sodium environment could be used between the irradiation test section and the upper structure section, the upper mechanism of INTA could be reused and testing costs would be drastically reduced. Moreover, the reactor load factor would be improved because of reduced handling time for INTA. In an attempt to gain this advantage, research and development of an electric connector in a sodium environment was carried out from 1988 to 1996 at PNC. As no previous R and D had been conducted in this area, this development activity was conducted in a boot strap manner. The first test was carried out for a small model fabrication, the second was for a water partial model, and the third was for a sodium partial model. Based on those tests, a prototype design specification of the connector was determined. In the sodium partial model test, the resilience of the electrical connector insulation to the sodium environment was investigated. However, severe cracking in the ceramic insulator caused by the high temperature sodium environment was discovered at the junction of ceramic insulator and metallic electrode. Although additional sodium partial tests were performed for various material combinations of ceramic insulators, metallic electrodes, brazing materials and metallization materials, the results of the tests were unsatisfactory. Therefore, it was decided that the development of the connector in sodium should cease at PNC in 1997. (J.P.N.)

  6. Cross-Diffusion Systems with Excluded-Volume Effects and Asymptotic Gradient Flow Structures

    Science.gov (United States)

    2017-04-01

    In this paper, we discuss the analysis of a cross-diffusion PDE system for a mixture of hard spheres, which was derived in Bruna and Chapman (J Chem Phys 137:204116-1-204116-16, 2012a) from a stochastic system of interacting Brownian particles using the method of matched asymptotic expansions. The resulting cross-diffusion system is valid in the limit of small volume fraction of particles. While the system has a gradient flow structure in the symmetric case of all particles having the same size and diffusivity, this is not valid in general. We discuss local stability and global existence for the symmetric case using the gradient flow structure and entropy variable techniques. For the general case, we introduce the concept of an asymptotic gradient flow structure and show how it can be used to study the behavior close to equilibrium. Finally, we illustrate the behavior of the model with various numerical simulations.

    Full Text Available The silverleaf whitefly is one of most important pests of tomato (Lycopersicon spp.. The use of host plant resistance to control this insect is an interesting, potentially useful technique, but in demand of more research. The objectives of this work were to evaluate the oviposition non-preference of Bemisia tabaci (Gennadius, 1889 biotype B for different tomato plant genotypes, evaluating the correlation between oviposition preference and pubescence in the genotypes, and analyzing the abaxial and adaxial surfaces of Lycopersicon pennellii leaflets under the scanning electron microscope. Four wild tomato genotypes, LA 716 (L. pennellii; PI 127826 and PI 127827 (L. hirsutum; PI 134417 (L. hirsutum f. glabratum, and two commercial genotypes, Santa Clara and Bruna VFN hybrid (L. esculentum were evaluated for number of eggs cm-2 in free and no-choice oviposition tests, using randomized block design and completely randomized design, respectively. The number of trichome was measured in 4 mm² and coefficients of correlation between number of trichomes and number of eggs were calculated. The wild genotypes LA 716 and PI 134417 were less preferred showing oviposition nonpreference resistance type in both tests. The Bruna VFN and Santa Clara were more preferred in free-choice test, while wild genotypes PI 127826 and PI 127827 were more preferred in no-choice test. L. pennellii leaflets presented glandular trichomes type IV in both surfaces. Santa Clara genotype presented higher density of trichomes, and B. tabaci biotype B presented higher preference to oviposition.A mosca-branca Bemisia tabaci (Gennadius, 1889 biótipo B é atualmente uma das principais pragas do tomateiro (Lycopersicon spp..

    Full Text Available We generated a map of wetlands in Argentina from the digital edition of the National Soil Inventory made by the National Institute of Agricultural Technology (Instituto Nacional de Tecnología Agropecuaria, INTA. Potential wetland areas were extracted from the map after an exhaustive analysis of the database and reassignment of the soil classes, by taking into account 1 soil taxonomic classes; 2 constraining factors (waterlogging, flooding, drainage impairment; and 3 cartographic categories, including lakes, lagoons, marshes and salt lakes. Estimated wetland area is about 600,000 km2, representing 21.5% of the national territory; it increases to 23% when considering salt lakes and deepwater bodies, but their surface is underestimated in the INTA database. Finally, we analyzed the distribution and abundance of wetland areas from different eco-regions of Argentina, and compared our results with current global wetland databases.

    The loan of an S2 VLBI recording terminal to Arecibo Observatory by the Space Geodynamics Laboratory, ISTS (now CRESTech), Canada, for support of the VSOP mission, opens the possibility of Arecibo participating in ground based VLBI observations. I.e. in collaboration with an international ad-hoc S2 array that has begun to operate under the Low Frequency VLBI Network (LFVN) project. LFVN arranges VLBI experiments using the telescopes in 11 countries which are equipped with S2 systems, together with the Penticton S2 correlator in Canada. A wide spectrum of baselines has been achieved, up to the largest on Earth, while the participation of Arecibo can ensure the high sensitivity of this S2 array. The first LFVN S2 observations including Arecibo were carried out at a wavelength of 18 cm on December 2, 1998, as part of INTAS98.5. This experiment with participation of three Russian antennas (Bear Lakes RT-64, Puschino RT-22 and Svetloe RT-32), Green Bank RT-43 and HartRAO RT-26 included 7 hrs of observation of weak sources on the Arecibo-Green Bank baseline. The successful processing of INTAS98.5 and two other observations (INTAS98.2 and INTAS99.4) by the Penticton correlator confirms the feasibility of this initiative (the post-processing was made at Astro Space Center, Russia). These VLBI observations may be continued with the Green Bank RT-100, Penticton RT-26 and Madrid RT-70. (The next S2 experiment is planned for October-November 2001). The recent equipping of Arecibo with a 92-cm receiver also opens new opportunities for LFVN cooperation, especially as there is a plan to also supply AlgoPark RT-46 and Penticton RT-26 in Canada with 92-cm facilities. Another field of interest for cooperation may be the radar VLBI research of the nearer planets with the S2 system recording of transmitted and reflected signals.

    Full Text Available Chilean newborn screening program began in 1984 through of a covenant between the National Ministry of Health and the Chilean University through its Institute of Nutrition and Food Technology (INTA with the aim of implementing a pilot study for neonatal detection of phenylketonuria (PKU in Santiago’s central area. In 1989 a program for neonatal diagnosis of PKU and congenital hypothyroidism (HC was initiated by INTA along with Santiago´s occidental health ministry rural area, which covered 20% of newborn population. PKU and HC had an incidence of 1:14,640 and 1:2000 living newborns respectively. These findings allowed the establishment of a favorable cost/benefit ratio which validated the implementation of a program with National character. In 1992 the Chilean Ministry of Health ruled the initiation of PKU and HC newborn screening program and by 1998 the coverage across the country was achieved. INTA is the National Reference Center for confirmation and long term treatment for PKU and HC patients. A follow-up program consists of medical, nutritional, neurological and psychological outcome evaluations as well as periodic biochemical testing in order to guarantee normal patient growth and development. To date 184 children have been diagnosed with classic or moderate PKU, all of them follow a strict monitoring program.

    Let the function $f: \\bar{\\R}^2_+ \\to \\C$ be such that $f\\in L^1_{\\loc} (\\bar{\\R}^2_+)$. We investigate the convergence behavior of the double integral $$\\int^A_0 \\int^B_0 f(u,v) du dv \\quad {\\rm as} \\quad A,B \\to \\infty,\\leqno(*)$$ where $A$ and $B$ tend to infinity independently of one another; while using two notions of convergence: that in Pringsheim's sense and that in the regular sense. Our main result is the following Theorem 3: If the double integral (*) converges in the regular sense, or briefly: converges regularly, then the finite limits $$\\lim_{y\\to \\infty} \\int^A_0 \\Big(\\int^y_0 f(u,v) dv\\Big) du =: I_1 (A)$$ and $$\\lim_{x\\to \\infty} \\int^B_0 \\Big(\\int^x_0 f(u,v) du) dv = : I_2 (B)$$ exist uniformly in $0int^A_0 \\int^B_0 f(u,v) du dv.$$ This can be considered as a generalized version of Fubini's theorem on successive integration when $f\\in L^1_{\\loc} (\\bar{\\R}^2_+)$, but $f\

    Full Text Available This study aimed at evaluating the effect of Azospirillum brasilense , a nitrogen - fixing bacterium, on flooded irrigated rice yield. Evaluations were carried out in a shaded nursery, with seedlings grown on an Alfisol. Were performed two sets of experiments. In the first, were carried out four experiments using the flooded rice cultivars INIA Olimar, Puitá Inta - CL, Br Irga 409 and Irga 424; these trials were set up as completely randomized design in a 5x4 factorial scheme, with four replications. Treatments consisted of five nitrogen rates (0, 40, 80, 120 and 160 kg ha - 1 and four levels of liquid inoculant Ab - V5 and Ab - V6 - A. brasilense (0, 1, 2 and 4 times the manufacturer's recommendation without seed treatment. In second set, were performed two experiments using the cultivars Puitá Inta - CL and Br Irga 409, arranged in the same design, but using a 4x2 factorial. In this set, treatments were composed of four levels of Ab - V5 and Ab - V6 - A. brasilense liquid inoculant (0, 1, 2 and 4 times the recommendation of 100 mL ha - 1 , using rice seeds with and without insecticide and fungicide treatment. Shoot dry matter, number of panicles, and rice grain yield per pot were the assessed variables. The results showed that rice seed inoculation with A. brasilense had no effects on rice grain yield of the cultivars INIA Olimar, Puitá Inta - CL, Br Irga 409 and Irga 424.

    Full Text Available Abstract Background A procedure to measure connectedness among herds was applied to a beef cattle population bred by natural service. It consists of two steps: (a computing coefficients of determination (CDs of comparisons among herds; and (b building sets of connected herds. Methods The CDs of comparisons among herds were calculated using a sampling-based method that estimates empirical variances of true and predicted breeding values from a simulated n-sample. Once the CD matrix was estimated, a clustering method that can handle a large number of comparisons was applied to build compact clusters of connected herds of the Bruna dels Pirineus beef cattle. Since in this breed, natural service is predominant and there are almost no links with reference sires, to estimate CDs, an animal model was used taking into consideration all pedigree information and, especially, the connections with dams. A sensitivity analysis was performed to contrast single-trait sire and animal model evaluations with different heritabilities, multiple-trait animal model evaluations with different degrees of genetic correlations and models with maternal effects. Results Using a sire model, the percentage of connected herds was very low even for highly heritable traits whereas with an animal model, most of the herds of the breed were well connected and high CD values were obtained among them, especially for highly heritable traits (the mean of average CD per herd was 0.535 for a simulated heritability of 0.40. For the lowly heritable traits, the average CD increased from 0.310 in the single-trait evaluation to 0.319 and 0.354 in the multi-trait evaluation with moderate and high genetic correlations, respectively. In models with maternal effects, the average CD per herd for the direct effects was similar to that from single-trait evaluations. For the maternal effects, the average CD per herd increased if the maternal effects had a high genetic correlation with the direct

    In this work, the partial results of the potential production of energy, starting from the biomass and the development of the crops, directed to the production of bio-fuels (Colza and Topinamur) in the North irrigation oasis of Mendoza, Argentina within the National Program of Bio-energy developed by INTA is presented. For the evaluation of the bio-energetic potential, derived from the biomass, the WISDOM methodology developed by FAO and implemented by INTA in Argentina was applied with the collaboration of national and provincial governmental entities that contribute local information The study of the potential production and the development of the bio-energetic crops have been carried out with the advising and participation of the experts of INTA of the studied crops. The province of Mendoza has semi-deserted agro-climatic characteristics. The type of soil and type of weather allows the production of great quality fruits and vegetables in the irrigated areas. The four great currents of water conform three oasis; Northeast, Center and South, which occupy the 3.67% of the surface of Mendoza. Today, Mendoza has 267,889 irrigated hectares, but the surface that was farmed by irrigation was near to the 400,000 ha. The climate contingencies, froze and hailstorm precipitations, plus the price instability cause great losses in the productive sector, taking it to the forlornness of the exploitations. The crop setting of these forlornness lands with crops directed to the production of bio-fuels and the utilization of the biomass coming from the agriculture activities and the agro industry (pruning of fruit trees, refuses of olive and vine, remnants of the peach industry, etc.) could assist the access to the energy in the rural areas, stimulating the economical improvement and the development in these communities.

    The integrin receptor alpha(v)beta(3) is overexpressed on the endothelial cells of growing tumors and on some tumor cells themselves. Radiolabeled alpha(v)beta(3) antagonists have demonstrated potential application as tumor imaging agents and as radiotherapeutic agents. This report describes the total synthesis of eight new HYNIC and DOTA conjugates of receptor alpha(v)beta(3) antagonists belonging to the quinolin-4-one class of peptidomimetics, and their radiolabeling with (99m)Tc (for HYNIC) and (111)In (for DOTA). Tethering of the radionuclide-chelator complexes was achieved at two different sites on the quinolin-4-one molecule. All such derivatives maintained high affinity for receptor alpha(v)beta(3) and high selectivity versus receptors alpha(IIb)beta(3), alpha(v)beta(5), alpha(5)beta(1). Biodistribution of the radiolabeled compounds was evaluated in the c-neu Oncomouse mammary adenocarcinoma model. DOTA conjugate (111)In-TA138 presented the best biodistribution profile. Tumor uptake at 2 h postinjection was 9.39% of injected dose/g of tissue (%ID/g). Activity levels in selected organs was as follows: blood, 0.54% ID/g; liver, 1.94% ID/g; kidney, 2.33% ID/g; lung, 2.74% ID/g; bone, 1.56% ID/g. A complete biodistribution analysis of (111)In-TA138 and the other radiolabeled compounds of this study are presented and discussed. A scintigraphic imaging study with (111)In-TA138 showed a clear delineation of the tumors and rapid clearance of activity from nontarget tissues.

    The Optical Monitoring Camera (OMC) on-board the INTEGRAL satellite has, as one of its scientific goals, the observation of a large number of variable sources previously selected. After almost 6 years of operations, OMC has monitored more than 100 000 sources of scientific interest. In this contribution we present the OMC Scientific Archive (http://sdc.laeff.inta.es/omc/) which has been developed to provide the astronomical community with a quick access to the light curves generated by this instrument.We describe the main characteristics of this archive, as well as important aspects for the users: object types, temporal sampling of light curves and photometric accuracy.

    2008-01-01

    The Optical Monitoring Camera on-board INTEGRAL (OMC) provides Johnson V band photometry of any potentially variable source within its field of view. Taking advantage of the INTEGRAL capabilities allowing the simultaneous observation of different kind of objects in the optical, X and gamma rays bands, we have performed a study of the optical counterparts of different high-energy sources. Up to now, OMC has detected the optical counterpart for more than 100 sources from the High Energy Catalog (Ebisawa et al., 2003). The photometrically calibrated light curves produced by OMC can be accessed through our web portal at: http://sdc.laeff.inta.es/omc

    Full Text Available Raphael Castiglioni Nascimento, Haryanne Mabel, Bruna Nunes Queiroz, Roberta ParesqueDepartamento de Ciências da Saúde, Centro Universitário Norte do Espírito Santo, São Mateus, ES, BrazilAbstract: Hypercaloric diets have been successfully used as experimental models of obesity. This work compared morphological characteristics of inferior gastrointestinal organs. The experiment lasted 10 weeks, during which the rats' food consumption, body weight, distance between the mouth and neck, distance between mouth and neck, distance between neck and tail, and abdominal circumference were evaluated weekly. After the sacrifice of the rats, 20 variables referring to inferior gastrointestinal morphology were assessed. The results comprised descriptive statistics of the data, analysis of main components, linear correlation, and t-tests. Significant differences were found between the two groups for the variables of abdominal circumference, retroperitoneal fat, ratio between retroperitoneal fat/animal weight, stomach weight, ratio between animal weight/intestine weight and mesentery/animal weight, length of small intestine, length of large intestine, and lateral line of the cecum. The data allow us to state that a hypercaloric diet can be responsible an increase in fat in the abdominal cavity as well as gastrointestinal morphological alterations, principally in stomach development. Keywords: gastrointestinal morphology; hypercaloric diet; diet-induced obesity

    Richardson Bruna, Katherine

    2010-06-01

    In this article, I return to the interactions of Augusto and his teacher in an "English Learner Science" classroom in a demographically-transitioning US Midwest community (Richardson Bruna and Vann in Cult Stud Sci Educ 2:19-59, 2007) and further engage a class-first perspective to achieve two main conceptual objectives. First, I examine Augusto's science education experience as a way of understanding processes Rouse (Towards a transnational perspective on migration: Race, class, ethnicity, and nationalism reconsidered. The New York Academy of Sciences, New York, 1992) refers to as "the disciplinary production of class-specific subjects" (p. 31). Coming from a subsistence farming community in rural Mexico to an industrialized meatpacking community in semi-rural Iowa, I describe how Augusto undergoes a change in his class identity (experiences a Class Transformation) that is not just reflected but, in fact, produced in his science class. Second, I examine the work Augusto does to resist these processes of disciplinary production as he reshapes his teacher's instruction (promotes a class transformation) through specific transnational social capital he leverages as peer mediation. My overall goals in the article are to demonstrate the immediate relevance of a socio-historical, situated perspective to science teaching and learning and to outline domains of action for an insurgent, class-cognizant, science education practice informed by transnational social capital, like Augusto's.

    The aim of this work was to compare the antiradical activity, total phenol content (TPC), and essential oil composition of Origanum vulgare spp. virens, Origanum x applii, Origanum x majoricum, and O. vulgare spp. vulgare cultivated in Argentina in different localities. The experiment was conducted in the research station of La Consulta (INTA-Mendoza), the research station of Santa Lucia (INTA-San Juan), and Agronomy Faculty of National University of La Pampa, from 2007 to 2008. The composition of the essential oils of oregano populations was independent of cultivation conditions. In total, 39 compounds were identified in essential oils of oregano from Argentina by means of GC-MS. Thymol and trans-sabinene hydrate were the most prominent compounds, followed by gamma-terpinene, terpinen-4-ol, and alpha-terpinene. O. vulgare vulgare is the only Origanum studied which is rich in gamma-terpinene. Among tested oregano, O. x majoricum showed the highest essential oil content, 3.9 mg g(-1) dry matter. The plant extract of O. x majoricum had greater total phenol content values, 19.36 mg/g dry weight, than the rest of oregano studied. To find relationships among TPC, free radical scavenging activity (FRSA), and climate variables, canonical correlations were calculated. The results obtained allow us to conclude that 70% of the TPC and FRSA variability can be explained by the climate variables (R(2) = 0.70; p = 8.3 x 10(-6)), the temperature being the most important climatic variable.

    VOSA (VO Sed Analyzer, http://svo2.cab.inta-csic.es/theory/vosa) is a public web-tool developed by the Spanish Virtual Observatory (http://svo.cab.inta-csic.es/) and designed to help users to (1) build Spectral Energy Distributions (SEDs) combining private photometric measurements with data available in VO services, (2) obtain relevant properties of these objects (distance, extinction, etc) from VO catalogs, (3) analyze them comparing observed photometry with synthetic photometry from different collections of theoretical models or observational templates, using different techniques (chi-square minimization, Bayesian analysis) to estimate physical parameters of the observed objects (teff, logg, metallicity, stellar radius/distance ratio, infrared excess, etc), and use these results to (4) estimate masses and ages via interpolation of collections of isochrones and evolutionary tracks from the VO. In particular, VOSA offers the advantage of deriving physical parameters using all the available photometric information instead of a restricted subset of colors. The results can be downloaded in different formats or sent to other VO tools using SAMP. We have upgraded VOSA to provide access to Gaia photometry and give a homogeneous estimation of the physical parameters of thousands of objects at a time. This upgrade has required the implementation of a new computation paradigm, including a distributed environment, the capability of submitting and processing jobs in an asynchronous way, the use of parallelized computing to speed up processes (˜ ten times faster) and a new design of the web interface.

    The vicuña (Vicugna vicugna) was indiscriminately hunted for more than 400 years and, by the end of 1960s, it was seriously endangered. At that time, a captive breeding program was initiated in Argentina by the National Institute of Agricultural Technology (INTA) with the aim of preserving the species. Nowadays, vicuñas are managed in captivity and in the wild to obtain their valuable fiber. The current genetic status of Argentinean vicuña populations is virtually unknown. Using mitochondrial DNA and microsatellite markers, we assessed levels of genetic diversity of vicuña populations managed in the wild and compared it with a captive population from INTA. Furthermore, we examined levels of genetic structure and evidence for historical bottlenecks. Overall, all populations revealed high genetic variability with no signs of inbreeding. Levels of genetic diversity between captive and wild populations were not significantly different, although the captive population showed the lowest estimates of allelic richness, number of mitochondrial haplotypes, and haplotype diversity. Significant genetic differentiation at microsatellite markers was found between free-living populations from Jujuy and Catamarca provinces. Moreover, microsatellite data also revealed genetic structure within the Catamarca management area. Genetic signatures of past bottlenecks were detected in wild populations by the Garza Williamson test. Results from this study are discussed in relation to the conservation and management of the species.

    2008-05-01

    The effects of genotype, plant growth and experimental factors (soil and year) on potato-associated bacterial communities were studied. Cultivars Achirana Inta, Désirée, Merkur and transgenic Désirée line DL12 (containing T4 lysozyme gene) were assessed in two field experiments. Cross-comparisons between both experiments were made using Désirée plants. Culture-dependent and -independent approaches were used to demonstrate effects on total bacterial, actinobacterial and Pseudomonas communities in bulk and rhizosphere soils and endospheres. PCR-denaturing gradient gel electrophoresis fingerprints prepared with group-specific primers were analyzed using multivariate analyses and revealed that bacterial communities in Achirana Inta plants differed most from those of Désirée and Merkur. No significant effects were found between Désirée and DL12 lines. Plant growth stage strongly affected different plant-associated communities in both experiments. To investigate the effect of plant-associated communities on plant health, 800 isolates from rhizospheres and endospheres at the flowering stage were tested for suppression of Ralstonia solanacearum biovar 2 and/or Rhizoctonia solani AG3. A group of isolates closely resembling Lysobacter sp. dominated in young plants. Its prevalence was affected by plant growth stage and experiment rather than by plant genotype. It was concluded that plant growth stage overwhelmed any effect of plant genotype on the bacterial communities associated with potato.

    The INTA Remote Sensing Laboratory has implemented a tool for the direct geolocation of satellite images. The core of the tool is a C code based on the "Earth Observation Mission CFI SW" from ESA. The tool accepts different types of inputs for satellite attitude (euler angles, quaternions, default attitude models). Satellite position can be provided either in ECEF or ECI coordinates. The line of sight of each individual detector is imported from an external file or is generated by the tool from camera parameters. Global DEM ACE2 is used to define ground intersection of the LOS.The tool has been already tailored for georeferencing images from the forthcoming Spanish Earth Observation mission SEOSat/Ingenio, and for the camera APIS onboard the INTA cubesat OPTOS. The next step is to configure it for the geolocation of Sentinel 2 L1b images.The tool has been internally validated by different means. This validation shows that the tool is suitable for georeferencing images from high spatial resolution missions. As part of the validation efforts, a code for simulating orbital info for LEO missions using EO-CFI has been produced.

    The greenhouse whitefly, Trialeurodes vaporariorum Westwood, is the most common and abundant whitefly in Argentine horticultural greenhouse crops, especially in tomato (Solanum lycopersicum). Resistance in some wild tomato relatives, such as S. peruvianum, S. habrochaites and S. pennellii to the greenhouse whitefly has been described. The Mi gene confers effective resistance against several species of insects, among them the sweet potato whitefly, Bemisia tabaci Gennadius. Resistance to T. vaporariorum was found in the prebreeding line FCN 93-6-2, derived from a cross between S. lycopersicum cultivar Uco Plata INTA (MiMi) and the wild line FCN 3-5 S. habrochaites. The purpose of this study was to evaluate resistance to T. vaporariorum in tomato genotypes and to study the relationship between this resistance and the presence of the REX-1 marker, which is linked to the Mi gene. In a free-choice assay, the average number of adults per leaf and the number of immatures on the middle and basal plant parts were analyzed. In a no-choice assay, the oviposition rate and adult survival rate were calculated. For all variables analyzed, FCN 3-5 was the most resistant strain. Variations were found in the F2 progeny between the prebreeding line FCN 13-1-6-1 and cv. Uco Plata INTA. Results from the F2 progeny indicate that resistance to T. vaporariorum may be polygenic with transgressive segregation. Whitefly resistance was found to be independent of the REX-1 marker.

    Full Text Available This paper is intended to describe INTA’s traditional characteristics and strategies of technology generation and transfer in order to facilitate the interpretation of the nature, sense and dynamics of its current transformation. For that purpose, the national social and productive needs that led to the creation and development of INTA should be understood so as to appreciate, from such a perspective, how they have become more complex at the same pace as the economic and technological organization did in the global and national contexts. In this regard, the strategy for the generation and transfer of technology, both as a consequence of the institutional experience and due to the requirements resulted from the growth of the technological, economic and social diversity in the Argentine agricultural and industrial sectors, derives from extreme and unequal realities that no longer limit to rural sectors. Such a set of changes presents unusual challenges to overcome through policy planning.Este trabajo se propone describir las características y estrategias tradicionales de generación y transferencia de tecnología del INTA, para así poder interpretar la naturaleza, sentido y dinámica de su transformación en la actualidad. Para ello se deberán comprender las necesidades sociales y productivas nacionales que llevaron a la creación y desarrollo del INTA y así, desde esta referencia, poder apreciar como esas necesidades se fueron complejizando al ritmo que lo hacía la organización económica y tecnológica, nacional y global. En este sentido, la estrategia en la generación y transferencia de tecnología, tanto como resultado de la propia experiencia institucional, como por las exigencias que implicaron el crecimiento de la diversidad tecnológica, económica y social en el sector agroindustrial argentino, responde a realidades extremas y desiguales que ya ni siquiera se limitan a sectores rurales.

    Full Text Available We generated a map of wetlands in Argentina from the digital edition of the National Soil Inventory made by the National Institute of Agricultural Technology (Instituto Nacional de Tecnología Agropecuaria, INTA. Potential wetland areas were extracted from the map after an exhaustive analysis of the database and reassignment of the soil classes, by taking into account 1 soil taxonomic classes; 2 constraining factors (waterlogging, flooding, drainage impairment; and 3 cartographic categories, including lakes, lagoons, marshes and salt lakes. Estimated wetland area is about 600,000 km2, representing 21.5% of the national territory; it increases to 23% when considering salt lakes and deepwater bodies, but their surface is underestimated in the INTA database. Finally, weanalyzed the distribution and abundance of wetland areas from different eco-regions of Argentina, and compared our results with current global wetland databases.Foi confeccionado um mapa de regiões úmidas da Republica Argentina, a partir da análise e reclassificação da edição digital do Atlas de Solos do pais, editado pelo Instituto Nacional de Tecnologia Agropecuária (INTA.

A superfície estimada das áreas alagadas é de aproximadamente 600.000 km2, correspondendo a 21,5% do território nacional. Se acrescentar as superfícies de salinas e corpos de água, essa área ascende para 23%, embora os dados destes últimos sistemas estejam subestimados na base de dados utilizados. Analisaram-se a distribuição e a abundância de áreas alagadas em diferentes ecorregiões do país, e os resultados foram comparados com os obtidos a partir de estimativas realizadas com outras bases de dados.

    The integrin receptor alphavbeta3 is overexpressed on the endothelial cells of growing tumors and on some tumor cells themselves. A radiolabeled alphavbeta3 antagonists belonging to the quinolin-4-one class of peptidomimetics (TA138) was previously shown to exhibit high affinity for integrin alphavbeta3 and high selectivity versus other integrin receptors. 111In-TA138 exhibited high tumor uptake in the c-neu Oncomouse mammary adenocarcinoma model and produced excellent scintigraphic images. This study describes the synthesis of eight divalent versions of TA138 and their evaluation as potential tumor radiotherapeutic agents. The two main variables in this study were the length of the spacer bridging the biotargeting moieties and the total negative charge of the molecules imparted by the cysteic acid pharmacokinetic modifiers. Receptor affinity was evaluated in a panel of integrin receptor affinity assays, and biodistribution studies using the 111In-labeled derivatives were carried out in the c-neu Oncomouse model. All divalent agents maintained the high receptor affinity and selectivity of TA138, and six of the eight 111In derivatives exhibited blood clearance that was faster than 111In-TA138 at 24 h postinjection (PI). All divalent agents exhibited tumor uptake and retention at 24 h PI that was higher than 111In-TA138. Tumor/organ ratios were improved for most of the divalent agents at 24 h PI in critical nontarget organs marrow, kidney, and liver, with the agents having intermediate-length spacers (29-43 A) showing the largest improvement. As an example, 111In-15 showed tumor uptake of 14.3% ID/g at 24 h PI and tumor/organ ratios as follows: marrow, 3.24; kidney, 7.29; liver, 8.51. A comparison of therapeutic indices for 90Y-TA138 and 177Lu-15 indicate an improved therapeutic index for the divalent agent. The implications for radiotherapeutic applications and the mechanism of this multivalent effect are discussed.

    The availability of SNP chips for massive genotyping has proven to be useful to genetically characterize populations of domestic cattle and to assess their degree of divergence. In this study, the Illumina BovineHD BeadChip genotyping array was used to describe the genetic variability and divergence among 7 important autochthonous Spanish beef cattle breeds. The within-breed genetic diversity, measured as the marker expected heterozygosity, was around 0.30, similar to other European cattle breeds. The analysis of molecular variance revealed that 94.22% of the total variance was explained by differences within individuals whereas only 4.46% was the result of differences among populations. The degree of genetic differentiation was small to moderate as the pairwise fixation index of genetic differentiation among breeds (F) estimates ranged from 0.026 to 0.068 and the Nei's D genetic distances ranged from 0.009 to 0.016. A neighbor joining (N-J) phylogenetic tree showed 2 main groups of breeds: Pirenaica, Bruna dels Pirineus, and Rubia Gallega on the one hand and Avileña-Negra Ibérica, Morucha, and Retinta on the other. In turn, Asturiana de los Valles occupied an independent and intermediate position. A principal component analysis (PCA) applied to a distance matrix based on marker identity by state, in which the first 2 axes explained up to 17.3% of the variance, showed a grouping of animals that was similar to the one observed in the N-J tree. Finally, a cluster analysis for ancestries allowed assigning all the individuals to the breed they belong to, although it revealed some degree of admixture among breeds. Our results indicate large within-breed diversity and a low degree of divergence among the autochthonous Spanish beef cattle breeds studied. Both N-J and PCA groupings fit quite well to the ancestral trunks from which the Spanish beef cattle breeds were supposed to derive.

  6. Hydrogeochemical processes controlling water and dissolved gas chemistry at the Accesa sinkhole (southern Tuscany, central Italy

    Full Text Available The 38.5 m deep Lake Accesa is a sinkhole located in southern Tuscany (Italy that shows a peculiar water composition, being characterized by relatively high total dissolved solids (TDS values (2 g L-1 and a Ca(Mg-SO4 geochemical facies. The presence of significant amounts of extra-atmospheric gases (CO2 and CH4, which increase their concentrations with depth, is also recognized. These chemical features, mimicking those commonly shown by volcanic lakes fed by hydrothermal-magmatic reservoirs, are consistent with those of mineral springs emerging in the study area whose chemistry is produced by the interaction of meteoric-derived waters with Mesozoic carbonates and Triassic evaporites. Although the lake has a pronounced thermocline, water chemistry does not show significant changes along the vertical profile. Lake water balance calculations demonstrate that Lake Accesa has >90% of its water supply from sublacustrine springs whose subterranean pathways are controlled by the local structural assessment that likely determined the sinking event, the resulting funnel-shape being then filled by the Accesa waters. Such a huge water inflow from the lake bottom (~9·106 m3 yr-1 feeds the lake effluent (Bruna River and promotes the formation of water currents, which are able to prevent the establishment of a vertical density gradient. Consequently, a continuous mixing along the whole vertical water column is established. Changes of the drainage system by the deep-originated waters in the nearby former mining district have strongly affected the outflow rates of the local mineral springs; thus, future intervention associated with the ongoing remediation activities should carefully be evaluated to preserve the peculiar chemical features of Lake Accesa.

    The availability of a wide range of immunosuppressive therapies has revolutionized the management of patients who have undergone solid organ transplantation (SOT). However, the cost of immunosuppressive drugs remains high. This situation has led to the development of generic equivalents, which are similar in quality, safety, and efficacy to their approved innovator drugs. There are data available for three generic brands, tacrolimus (Intas), tacrolimus (PharOS), and tacrolimus (Sandoz). Bioequivalence has been demonstrated for generic tacrolimus (Sandoz) within a narrow therapeutic range to its innovator tacrolimus drug (Prograf) in both healthy volunteers and kidney transplant patients. Clinical experience with this generic tacrolimus formulation has also been established in both de novo and conversion patients who have undergone kidney and liver transplantation, as well as in conversion of other SOT patients, including lung and heart recipients.

    A simple analytical method using low volumes of solvent for determining selected PAHs and NPAHs in PM samples is presented. The proposed extraction method was compared with pressurized fluid (PFE) and microwave (MC) extraction techniques and intermediate precision associated to analytical measurements were estimated. Extraction by agitation with 8 mL of dichloromethane yielded recoveries above 80% compared to those obtained from PFE extraction. Regarding intermediate precision results, values between 10-20% were reached showing increases of dispersion for compounds with high volatility and low levels of concentration. Within the framework of the INTA/CIEMAT research agreement for the PM characterization in gas turbine exhaust, the method was applied for analysis of aluminum foil substrates and quartz filters with mass loading ranged from 0.02 to 2 mg per sample.

    The disposal of couples of images of the same landscape acquired with two spatial resolutions gives the opportunity to assess the in-flight Modulation Transfer Function (MTF) of the lower resolution sensor in the common spectral bands. For each couple, the higher resolution image stands for the landscape so that the ratio of the spectra obtained by FFT of the two images, gives the lower resolution sensor MTF. This paper begins with a brief recall of the method including the aliasing correction. The next step presents the data to be processed, provided by the Instituto Nacional de Tecnica Aeroespacial (INTA). The model of the AHS MTF is described. The presentation of the corresponding AHS results naturally follows. Last part of the paper consists in a comparison with other measurements: measurements obtained with the edge method and laboratory measurements.

    In that work, a hot sd selection procedure was defined and tested by means of a thorough retrieval, with the aid of VO tools, of multicolour photometry and astrometric information from stellar catalogues. A filtering procedure to distinguish among different types of objects was designed to obtain a hot sd sample with a low contamination factor. The method was tested on two sky regions: the Kepler FoV2 and a region of 300deg2 around (RA:225°,DE:5°) obtaining a high rate of success (above 80 per cent) in finding new uncatalogued hot sds. Temperatures were provided by fitting their spectral energy distribution (SED), and considering two-atmosphere fits for those objects with a clear infrared (IR) excess, a signature of the possible presence of a cool companion.

    Full Text Available Os marmeleiros sempre foram propagados comercialmente através de enraizamento de estacas. Devido à falta de vigor das mudas, principalmente nos primeiros anos após o plantio, uma série de trabalhos foram desenvolvidos no Brasil a fim de viabilizar a utilização do marmeleiro 'Japonês' (Chaenomeles sinensis Koehne como porta-enxerto para marmelos. Frente à falta de informações, desenvolveu-se este experimento com o objetivo de verificar o desenvolvimento de diferentes cultivares de marmeleiros enxertadas sobre esse porta-enxerto. Os marmeleiros 'Japonês', 'MC', 'Adams', 'Van Deman', 'Provence', 'Cheldow', 'Smyrna', 'Rea's Mamouth', 'De Patras', 'De Vranja', 'Lajeado', 'Champion', 'Mendoza Inta-37', 'Alongado', 'Meech Prolific', 'Bereckzy', 'Alaranjado', 'Kiakami', 'Du Lot', 'Radaelli', 'CTS 207', 'D'Angers', 'Zuquerinetta', 'BA 29', 'Constantinopla', 'Marmelo Pêra', 'Apple', 'Portugal', 'Füller', 'Meliforme' e 'Pineapple' foram enxertados através de garfagem em mudas de 'Japonês', pelo método em fenda cheia. Foram utilizados garfos com três gemas, coletados de plantas-matrizes. As mudas foram mantidas em viveiro, sendo avaliadas, após 60 dias, a porcentagem de garfos brotados. O comprimento e diâmetro médio do enxerto foram avaliados aos 60; 90; 120 e 150 dias após a realização da enxertia. Concluiu-se que os marmeleiros apresentaram boa afinidade com o porta-enxerto 'Japonês'.

    An essential step in 2D DIGE-based analysis of differential proteome profiles is the accurate and sensitive digitalisation of 2D DIGE gels. The performance progress of commercially available charge-coupled device (CCD) camera-based systems combined with light emitting diodes (LED) opens up a new possibility for this type of digitalisation. Here, we assessed the performance of a CCD camera system (Intas Advanced 2D Imager) as alternative to a traditionally employed, high-end laser scanner system (Typhoon 9400) for digitalisation of differential protein profiles from three different environmental bacteria. Overall, the performance of the CCD camera system was comparable to the laser scanner, as evident from very similar protein abundance changes (irrespective of spot position and volume), as well as from linear range and limit of detection.

    In the last two decades, Spain has built up a strong IR community which has successfully contributed to space instruments, reaching Co-PI level in the SPICA mission (Space Infrared Telescope for Cosmology and Astrophysics). Under the SPICA mission, INTA, focused on the SAFARI instrument requirements but highly adaptable to other missions has designed a cryogenic low dissipation filter wheel with six positions, taking as starting point the past experience of the team with the OSIRIS instrument (ROSETTA mission) filter wheels and adapting the design to work at cryogenic temperatures. One of the main goals of the mechanism is to use as much as possible commercial components and test them at cryogenic temperature. This paper is focused on the design of the filter wheel, including the material selection for each of the main components of the mechanism, the design of elastic mount for the filter assembly, a positioner device designed to provide positional accuracy and repeatability to the filter, allowing the locking of the position without dissipation. In order to know the position of the wheel on every moment a position sensor based on a Hall sensor was developed. A series of cryogenic tests have been performed in order to validate the material configuration selected, the ball bearing lubrication and the selection of the motor. A stepper motor characterization campaign was performed including heat dissipation measurements. The result is a six position filter wheel highly adaptable to different configurations and motors using commercial components. The mechanism was successfully tested at INTA facilities at 20K at breadboard level.

    Full Text Available Em regiões de altitudes elevadas do sul do Brasil, predominam perfis de solos com coloração bruna ou bruno-amarelada, em conseqüência do clima frio e úmido, que favorece a formação e, ou, persistência de óxidos de ferro na forma de goethita, causando o amarelecimento completo dos solos. Entretanto, em alguns locais, constatam-se perfis de solos com horizontes superficiais brunados, mas que, em profundidade, apresentam cores avermelhadas, o que parece constituir relíquia de clima pretérito mais seco e quente que o atual. O presente trabalho objetivou estudar a gênese das feições citadas, por meio da avaliação das características estruturais dos óxidos de ferro goethita e hematita nos horizontes brunados e vermelhos. Para tanto, foram descritos e amostrados no Planalto de Lages dois perfis de Nitossolos Vermelhos (Podzólicos Vermelho-Escuros, com horizontes superficiais brunados. Além da caracterização analítica usual, avaliaram-se, através de difratometria de raios X, as características estruturais dos óxidos de ferro de horizontes dos perfis, bem como em crosta laterítica, pedotúbulos e nódulos de gibbsita. Diferenças no padrão da goethita entre os horizontes brunados e vermelhos, bem como similaridade no padrão da hematita ao longo dos perfis, evidenciam que a hematita e, possivelmente, parte da população de goethita com menor substituição de ferro por alumínio tenham sido preferencialmente dissolvidas nos horizontes superficiais. O amarelecimento superficial parece ter sido resultante da persistência da população de goethitas com maior substituição de ferro por alumínio e da neoformação de goethitas, cujas características de maior substituição isomórfica de ferro por alumínio indicam terem sido formadas em condições ambientais diferentes das que prevaleceram na formação dos horizontes subsuperficiais vermelhos.

Nanostructured lipid systems are able to potentiate the action of plant extracts, reducing the required dose and side effects and improving antimicrobial activity. This work aims to evaluate a nanostructured lipid system that was developed as a strategy to improve the anti-Candida albicans activity of hydroethanolic extracts of stems and leaves from Astronium sp. The antifungal activity against C. albicans (ATCC 18804 was evaluated in vitro by a microdilution technique. In addition to the in vitro assays, the Astronium sp. that showed the best antifungal activity and selectivity index was submitted to an in vivo assay using a model of vulvovaginal candidiasis infection. In these assays, the extracts were either used alone or were incorporated into the nanostructured lipid system (comprising 10% oil phase, 10% surfactant, and 80% aqueous phase. The results indicated a minimal inhibitory concentration of 125.00 µg/mL before incorporation into the nanostructured system; this activity was even more enhanced when this extract presented a minimal inhibitory concentration of 15.62 µg/mL after its incorporation.

Nanomaterials are an alternative to conventional antibiotic compounds, because bacteria are unlikely to develop microbial resistance against nanomaterials. In the past decade, graphene oxide (GO has emerged as a material that is often used to support and stabilize silver nanoparticles (AgNPs for the preparation of novel antibacterial nanocomposites. In this work, we report the synthesis of the graphene-oxide silver nanocomposite (GO-Ag and its antibacterial activity against relevant microorganisms in medicine. Materials and methods: GO-Ag nanocomposite was synthesized through the reduction of silver ions (Ag+ by sodium citrate in an aqueous GO dispersion, and was extensively characterized using ultraviolet-visible absorption spectroscopy, X-ray diffraction, thermogravimetric analysis, X-ray photoelectron spectroscopy, and transmission electron microscopy. The antibacterial activity was evaluated by microdilution assays and time-kill experiments. The morphology of bacterial cells treated with GO-Ag was investigated via transmission electron microscopy. Results: AgNPs were well distributed throughout GO sheets, with an average size of 9.4±2.8 nm. The GO-Ag nanocomposite exhibited an excellent antibacterial activity against methicillin-resistant S. aureus, Acinetobacter baumannii, Enterococcus faecalis, and Escherichia coli.

The aim of this study was to evaluate the cardiac autonomic modulation, via heart rate variability after an acute session of RE applied at different intensities in COPD patients. Patients and methods: Twelve COPD patients underwent an acute session of RE with an intensity of 60% and another of 90% of the one repetition maximum test. For analysis of autonomic modulation, heart rate was recorded beat-by-beat for 20 minutes at rest and after the training session. Heart rate variability indexes were obtained in the time and frequency domains for the assessment of autonomic modulation. Results: Regardless of exercise intensity, RE acute sessions influenced the autonomic modulation when the recovery period was compared with the baseline. An increase in standard deviation of normal to normal RR intervals was observed throughout recovery time after the RE, as compared to baseline in both protocols: 60% and 90% of the one repetition maximum test. The spectral component of low frequency index (ms was higher throughout recovery when compared to baseline in both protocols. The same was also observed in the spectral component of high frequency index (ms for the protocols of 60% and 90%. Conclusion: RE sessions impact on the autonomic modulation of COPD patients by promoting

    The cultivation of transgenic glyphosate-resistant crops has been the most rapidly adopted crop technology in Argentina since 1997. Thus, more than 180 million liters of the broad-spectrum herbicide glyphosate (N - phosphonomethylglicine) are applied every year. The intensive use of glyphosate combined with geomorphometrical characteristics of the Pampa region is a matter of environmental concern. An integral component of assessing the risk of soil contamination in farm fields is to describe the spatial distribution of the levels of contaminant agent. Application of pedometric techniques for this purpose has been scarcely demonstrated. These techniques could provide an estimate of the concentration at a given unsampled location, as well as the probability that concentration will exceed the critical threshold concentration. In this work, a pedometric technique for assessing the spatial distribution of glyphosate in farm fields was developed. A field located at INTA Barrow, Argentina (Lat: -38.322844, Lon: -60.25572) which has a great soil spatial variability, was divided by soil-specific zones using a pedometric technique. This was developed integrating INTA Soil Survey information and a digital elevation model (DEM) obtained from a DGPS. Firstly, 10 topographic indices derived from a DEM were computed in a Random Forest algorithm to obtain a classification model for soil map units (SMU). Secondly, a classification model was applied to those topographic indices but at a scale higher than 1:1000. Finally, a spatial principal component analysis and a clustering using Fuzzy K-means were used into each SMU. From this clustering, three soil-specific zones were determined which were also validated through apparent electrical conductivity (CEa) measurements. Three soil sample points were determined by zone. In each one, samples from 0-10, 10-20 and 20-40cm depth were taken. Glyphosate content and AMPA in each soil sample were analyzed using de UPLC-MS/MS ESI (+/-). Only

Interaction between water availability and size seed in relation to lipid and lignoseric acid content were also detected. The greatest water availability produced seeds with more lipid content. Moreover, probably due to an indirect effect of less soil temperature, the insaturated lipid concentration was increased as can be seen in the less O/L ratio and augmented IY.Se evaluaron las modificaciones que se producen en el contenido de materia grasa, perfil de ácidos grasos, relación oleico / linoleico (O/L e índice de yodo (IY de las semillas de maní (cv.

En relación al tamaño de las semillas variaron el contenido de oleico, eicosenoico y behénico. Se encontró interacción entre disponibilidad hídrica y tamaño de semillas para el contenido de aceite y de ácido lignosérico. La mayor disponibilidad de agua produjo semillas con mayor contenido de aceite y además, probablemente debido a un efecto indirecto de disminución de la temperatura de suelo, se aumentó el grado de insaturación del aceite, lo cual se evidenció a través de una relación O/L menor y un IY superior.

    BrO and OClO are two of the most important halogen radicals involved in the ozone destruction. Although chlorine dioxide (OClO) does not participate directly in the destruction of ozone, observations of OClO are a good indicator for chlorine activation in the polar vortex based on the assumption of OClO concentration is linearly dependent on the ClO concentration. Accurate measurements of both components (BrO, OClO) are important to understand the halogen chemistry in the highly perturbed spring atmosphere in the polar regions, especially in Antarctica, where BrO and OClO ground-based measurements are very sparse and satellite observations have some limitations. Ground-based MAXDOAS observations were performed at Belgrano (78°S) and Marambio (64°S) by IAA/INTA during 2015. Stations are located close in longitude but separated 14° in latitude. Belgrano is representative of an in-polar vortex station during the winter-spring season until the vortex breakdown, while Marambio is frequently located in the edge region of the vortex. Simultaneous measurements of halogen species in both stations, using the same kind of instrumentation developed at INTA, are key factor to characterize the distribution of halogens, ozone and NO2 in two different although close scenarios and, also, to get a better understanding of the mechanisms that release halogens into the atmosphere. We report on the UV/Vis spectroscopic measurements performed during 2015 showing stratospheric BrO, OClO, NO2 and O3 above both stations. We present the seasonal evolution of these gases, as well as their role in the ozone depletion observed during the austral spring. The south polar vortex of 2015 was unusually stable and long-lived, so ozone depletion lasted longer than seen in recent years. A detailed analysis of the heat flux and of the position of the stations with respect to the polar vortex will be presented using equivalent latitude al 550 and 475 K isentropic levels.

    The Rover Environmental Monitoring Station (REMS) on the Mars Science Laboratory (MSL) offers the opportunity to explore the near surface atmospheric conditions and, in particular will shed new light into the heat budget of the Martian surface. This is important for studies of the atmospheric boundary layer (ABL), as the ground and air temperatures measured directly by REMS control the coupling of the atmosphere with the surface [Zurek et al., 1992]. This coupling is driven by solar insolation. The ABL plays an important role in the general circulation and the local atmospheric dynamics of Mars. One of the REMS sensors, the ground temperature sensor (GTS), provides the data needed to study the thermal inertia properties of the regolith and rocks beneath the MSL rover. The GTS includes thermopile detectors, with infrared bands of 8-14 µm and 16-20 µm [Gómez-Elvira et al., 2012]. These sensors are clustered in a single location on the MSL mast and the 8-14 µm thermopile sounds the surface temperature. The infrared radiation reaching the thermopile is proportional to the emissivity of the surface minerals across these thermal wavelengths. We have developed a radiative transfer retrieval method for the REMS GTS using a database of thermal infrared laboratory spectra of analogue minerals and their mixtures. [Martín Redondo et al. 2009, Martínez-Frías et al. 2012 - FRISER-IRMIX database]. This method will be used to assess the perfomance of the REMS GTS as well as determine, through the error analysis, the surface temperature and emissivity values where MSL is operating. Comparisons with orbiter data will be performed. References Gómez-Elvira et al.

    Penicillium is an important genus of ascomycetous fungi in the environment and in food and drug production. This paper aims to investigate statins and antipathogenic natural products from a Penicillium commune environmental isolate. Fractions (F1, F2, F3 and F4) were obtained from an ethyl acetate extract. Direct insertion probe/electron ionisation/ion trap detection mass spectrometry (MS and MS/MS) identified lovastatin (1) in F1, while GC-MS showed that 3-isobutylhexahydropyrrolo[1,2-a]pyrazine-1,4-dione (2) was the main constituent of F2 (49.34%). F4 presented 3 (16.38%) as an analogue of 2 and their known structures were similar to that of an autoinducer-signal. F1 produced a significant decrease in the Pseudomonas aeruginosa biofilms, which is the main cause of bacterial pathogenicity. F2 and F4 were effective against Staphylococcus aureus biofilms, but when F2 was associated with oxacillin, it showed an important activity against both bacteria. These novel results suggest that P. commune INTA1 is a new source of promising antipathogenic products.

    The increase in biofuels production has been rising in the last ten years at a high rate. Argentina as one of the main crop producers in the world has a great potential to contribute with high volumes of biofuels. At present time common crops are used for large scale production but new alternatives are under study in different regions of the country. The increase in pressure for expansion also raises concerns on the impact on ecology issues such as soil erosion and biodiversity. Looking at a national level INTA has been working on the construction of a GIS were different crops were placed. The purpose is to identify critical information, to raise a methodology to obtain accurate and up-to date thematic maps using satellite images, to feed a GIS and to integrate the different layers to estimate biomass potentials for energy supply in our country, assessing potential land availability for biofuel crops or plantations to be made with ecological, economic and social sustainability bases.

    Formerly the world's fourth largest lake by area, the Aral Sea is presently undergoing extreme desiccation due to large-scale irrigation strategies implemented in the Soviet era. As part of the INTAS-funded CLIMAN project into Holocene climatic variability and the evolution of human settlement in the Aral Sea basin, fossil diatom assemblages contained within a sediment core obtained from the Aral Sea have been applied to a diatom-based inference model of conductivity ( r2 = 0.767, RMSEP = 0.469 log 10 μS cm - 1). This has provided a high-resolution record of conductivity and lake level change over the last ca. 1600 yr. Three severe episodes of lake level regression are indicated at ca. AD 400, AD 1195-1355 and ca. AD 1780 to the present day. The first two regressions may be linked to the natural diversion of the Amu Darya away from the Aral Sea and the failure of cyclones formed in the Mediterranean to penetrate more continental regions. Human activity, however, and in particular the destruction of irrigation facilities are synchronous with these early regressions and contributed to the severity of the observed low stands.

However, scant attention has been focused on these questions in Latin American contexts, despite growing concerns about substance use among Latin American youth. Using data from a sample of 866 Chilean youth, we examined the relationship of family and neighborhood factors with youth substance abuse. We found that in a Latin American context, access to substances is an important predictor of use, but that neighborhood effects differ for marijuana use as opposed to cigarettes or alcohol. Age of youth, family and peer relationships, and gender all play significant roles in substance use. The study findings provide additional evidence that the use of substances is complex, whereby individual, family, and community influences must be considered jointly to prevent or reduce substance use among adolescents.Keywords: substance use, adolescence, international, peers

    Full Text Available Juan Francisco Cabello,1 Deborah Marsden21Genetics and Metabolic Disease Laboratory, Nutrition and Food Technology Institute (INTA, University of Chile, Santiago, Chile; 2Division of Genetics and Genomics, Boston Children's Hospital, Boston, MA, USA Abstract: Pompe disease (acid alpha-glucosidase deficiency, OMIM 232300 is a rare lysosomal storage disorder due to autosomal recessive mutations in the GAA gene. It has also been called acid maltase deficiency and glycogen storage disease type II. There is a broad clinical presentation: the most severe form that presents in the first few months of life with cardiomyopathy and generalized muscle weakness that rapidly progresses to death from cardio-respiratory failure in the first year of life (infant-onset Pompe disease. A more slowly progressive disease, with little or no cardiac involvement, presents with proximal myopathy and/or pulmonary insufficiency, from the second year of life to late adulthood (late-onset Pompe disease. The recent development and introduction of enzyme replacement therapy with intravenous infusion of recombinant human acid alpha-glucosidase have made a major improvement in the morbidity and mortality of this disease. New therapies are also in development. With the availability of treatment, diagnostic methods have also improved, allowing for earlier recognition and potential early therapeutic intervention. The advent of newborn screening for Pompe disease may identify patients who can be treated before significant irreversible disease has occurred.

    Being involved in ozone destruction cycles, the halogen oxides (containing Br, Cl or I) are relevant reactants not only in the stratosphere but also in the troposphere. In order to characterize the presence of halogen oxides in the Antarctic boundary layer (BL), two MAX-DOAS instruments developed by INTA were installed at two different Antarctic sites: Marambio (64° S) and Belgrano (78° S). Note that, although both stations sit on pristine and remote locations, the surroundings of each station is unique and so is the atmospheric chemistry. Here we present the results of the measurements of BrO and IO performed in the sunlit atmosphere of both stations during 2015. We will focus on the activation of reactive bromine, its sources and sinks and its vertical distribution in the troposphere. We will also address the differences found regarding the bromine content of the BL in the two Antarctic sites. Moreover, we will investigate the presence of IO in the Antarctic BL.

    Torres, C.; Redondas, A.; Cuevas, E.; Lakkala, K.; Taalas, P.

    The Antarctic Network of the MAR-Project (Measurement of Antarctic Radiance for monitoring the ozone layer) is the result of a co-operation among the Instituto Nacional de Meteorología (INM, Spain), Instituto Nacional de Técnica Aeroespacial (INTA, Spain), the Instituto Antártico Argentino - Dirección Nacional del Antártico (IAA/DNA), the Finnish Meteorological Institute (FMI), and the Centro Austral de Investigaciones Científicas (CADIC, Argentina). This network consists on three NILU-UV6 multichannel filter radiometers installed at the Argentinean Antarctic bases of Vicecomodoro Marambio and Belgrano II, and at the CADIC in Ushuaia, respectively. These instruments measure at five UV channels (305, 3120, 320, 340 and 380 nm) and PAR (400 - 700 nm). Quality control and quality assurance systems of the network give us information for irradiance correction. Quality control is based on the 2-week lamp tests performed at each station, and provides quantitative information about the stability of each instrument. Quality assurance, which is performed twice a year by the FMI, lies in inter-comparisons between the travelling reference instrument and the station instruments. These intercomparisons provide calibration coefficients for each channel. Ozone can be derived from the NILU-UV6 instruments using the 305 nm / 320 nm ratio. Ozone data series before and after irradiance correction are compared against independent ozone measurements from the TOMS, the Dobson and the UV-VIS instruments at the Ushuaia station.

    The use of passive and active remote sensing systems has largely contributed to advance our understanding of important atmospheric phenomena. Here we present a compact and portable passive DOAS (Differential Optical Absorption Spectroscopy) system, developed for measuring the vertical column density (VCD) of multiple atmospheric trace gases. We highlight the main characteristics of the system components: a mini-spectrometer (HR4000, Ocean Optics), two optical fibers (400 μm of core, 6 m and 25 cm of longitude), an external shutter and the control/data processing software. Nitrogen dioxide (NO2) and ozone (O3) VCDs are derived from solar spectra acquired during twilights (87° - 91° zenithal angles) using the DOAS technique. The analysis is carried out by solving the Beer-Lambert-Bouger (BLB) law for the main atmospheric absorbers at selected wavelength ranges. The algorithm minimizes the fitting residuals to the BLB law, having as unknown the slant column density (SCD) of the species to determine. We present measurements carried out at the Marambio Antarctic Base (64° 14' 25'' S; 56° 37' 21'' W, 197 m asl) during January - February 2008. In addition, we compare our results with co-located measurements performed with EVA, a visible absorption spectrometer of Instituto Nacional de Técnica Aeroespacial (INTA, Spain), a Dobson spectrophotometer of Servicio Meteorológico Nacional (SMN, Argentine) and the Ozone Monitoring Instrument (OMI), on board AURA satellite.

    The Spanish Ministry of Industry, Tourism and Trade (MITyC) and the Ministry of Defense (MoD) signed an agreement in 2007 for the development of a "Spanish Earth Observation Satellite System" based, in first instance, on two satellites: a high resolution optical satellite, called SEOSAT/Ingenio, and a radar satellite based on SAR technology, called SEOSAR/Paz. SEOSAT/Ingenio is managed by MITyC through the Centre for the Development of Industrial Technology (CDTI), with technical and contractual support from the European Space Agency (ESA). HISDESA T together with the Spanish Instituto Nacional de Técnica Aeroespacial (INTA, National Institute for Aerospace Technology) will be responsible for the in-orbit operation and the commercial operation of both satellites, and for the technical management of SEOSAR/Paz on behalf of the MoD. In both cases EADS CASA Espacio (ECE) is the prime contractor leading the industrial consortia. The ground segment development will be assigned to a Spanish consortium. This system is the most important contribution of Spain to the European Programme Global Monitoring for Environment and Security, GMES. This paper presents the Spanish Earth Observation Satellite System focusing on SEOSA T/Ingenio Programme and with special emphasis in the potential contribution to the ESA Third Party Missions Programme and to the Global Monitoring for Environment and Security initiative (GMES) Data Access.

    2011-01-01

    This work presents the results of an experimental study on droplet deformation and breakup near the leading edge of an airfoil. The experiment was conducted in the rotating rig test cell at the Instituto Nacional de Tecnica Aeroespacial (INTA) in Madrid, Spain. An airfoil model placed at the end of the rotating arm was moved at speeds of 50 to 90 m/sec. A monosize droplet generator was employed to produce droplets that were allowed to fall from above, perpendicular to the path of the airfoil at a given location. High speed imaging was employed to observe the interaction between the droplets and the airfoil. The high speed imaging allowed observation of droplet deformation and breakup as the droplet approached the airfoil near the stagnation line. A tracking software program was used to measure from the high speed movies the horizontal and vertical displacement of the droplet against time. The velocity, acceleration, Weber number, Bond number, Reynolds number, and the drag coefficients were calculated along the path of a given droplet from beginning of deformation to breakup and/or hitting the airfoil. Results are presented for droplets with a diameter of 490 micrometers at airfoil speeds of 50, 60, 70, 80 and 90 m/sec

    A number of chemical species present in the stratosphere in very small concentrations (parts per billion and even smaller) contribute significantly to its chemical balance. One of the main stratospheric trace gases is nitrogen dioxide (NO2). This species acts as a restrictive agent for stratospheric ozone destruction (due to the chlorine monoxide), hence the importance of its study. We present a preliminary analysis of passive remote sensing measurements carry out at the Marambio Argentinean Antarctic Base (64.233° S; 56.616° W; 197 m amsl) during the months of January—February of 2008. The spectroscopy system consists of an optical fiber (400 μm core diameter and 6 m of longitude) and a portable spectral analyzer (spectrometer HR4000, Ocean Optics). The device analyzes diffuse solar spectral irradiance in the UV-visible range (290-650 nm), collected and transferred by a zenith-pointing optical fiber. The NO2 vertical column density (VCD) is derived from the radiance spectra using the DOAS (Differential Optical Absorption Spectroscopy) technique. The system and technique allow for simultaneous measurements of different species of interest on a variety of meteorological conditions. The vertical columns obtained are compared with co-located measurements performed with EVA, a visible absorption spectrometer operated by the Instituto Nacional de Técnica Aeroespacial (INTA), Spain.

The experiment was conducted in the rotating rig test cell at the Instituto Nacional de Tecnica Aeroespacial (INTA) in Madrid, Spain. The airfoil model was placed at the end of the rotating arm and a monosize droplet generator produced droplets that fell from above, perpendicular to the path of the airfoil. The interaction between the droplets and the airfoil was captured with high speed imaging and allowed observation of droplet deformation and breakup as the droplet approached the airfoil near the stagnation line. Image processing software was used to measure the position of the droplet centroid, equivalent diameter, perimeter, area, and the major and minor axes of an ellipse superimposed over the deforming droplet. The horizontal and vertical displacement of each droplet against time was also measured, and the velocity, acceleration, Weber number, Bond number, Reynolds number, and the drag coefficients were calculated along the path of the droplet to the beginning of breakup. Droplet deformation is defined and studied against main parameters. The high speed imaging allowed observation of the actual mechanism of breakup and identification of the sequence of configurations from the initiation of the breakup to the disintegration of the droplet. Results and comparisons are presented for droplets of diameters in the range of 500 to 1800 microns, and airfoil velocities of 70 and 90 m/sec.

    Phenylketonuria (PKU) is a genetic disorder caused by a partial or complete mutation of the enzyme phenylalanine hydroxylase (PHA), fact that produces high levels of phenylalanine in blood resulting in mental retardation if not diagnosed during the neonatal period. Treatment consists of a phenylalanine (Phe) restricted diet. Several studies have shown that due to restriction of animal protein, this diet is deficient in fatty acids such as alfalinolenic acid (ALA) and provides high levels of linoleic acid (LA). The objective of this study was to determine the lipid composition of the diet consumed by children with early-diagnosed PKU. Lipid composition of the Phenylalanine restricted diet consumed by 29 children with PKU and in follow-up at INTA, University of Chile, were analyzed. Children were paired by sex and age with a control group. A twenty-four hour dietary recall was performed for 3 consecutive days and total fatty acid intake, including saturated, monounsaturated, polyunsaturated, LA and ALA, were calculated. In the restricted diet of children with PKU, 31.8% of total calories are from fat, 13% of which are LA and 0.2% ALA, showing significant differences as compared to the control group. The ratio of saturated:monounsaturated:polyunsaturated fatty acids was 1:1.7:3.9 and the ratio of LA:ALA was ten-fold higher than the recommended ratio of 115:1. It is concluded that the Phenyalanine restricted diet of Chilean children with PKU is high in LA and low in ALA.

    Full Text Available The paper reports on new and previously not well-known data on insufficiently studied fauna of aphids living on coniferous trees in Central Siberia of the basin of Yenisei river. This region is the extensive transect of latitudinal geographic zones from semi-desert in the South to the arctic deserts in the North. That is why this region is very peculiar. This is the reason for insufficient study of regional entomological fauna. Aphids (Homoptera: Aphidoideaare a very taxonomically and ecologically heterogeneous group of insects. The aphids living on conifer trees are notstudied completely on the territory of Yenisei basin. Due to this, the studying of not well-known and economicallyimportant aphids is actual. For example, the insufficient study of regional aphids is confirmed by the fact, that duringthree weeks only of the work for INTAS-94-0930 Project two new aphid species were found and described on thisterritory. Also, the new species of family Mindaridae, which was described in Mongolia in 1980, was found in Siberiafor the first time. These finds indicate the real possibility to describe an interesting conifer aphid complex in the absolutely unstudied forested territory between Angara and Lower Tunguska rivers. Geographical location, dates ofcollection and feeding preferences of different species are described. A general review of Yenisei basin Siberian aphidfauna is suggested for the first time ever.

    The purpose of this study was to evaluate a set of teaching materials on food, nutrition and agriculture, adapted at the Institute of Nutrition and Food Technology (INTA), University of Chile, within the scope of a project with AID and the School of Agronomy of the Chilean Catholic University (U. C.) aimed at incorporating the teaching of human nutrition into the curriculum of Latin American agronomists. A one semester course (54 hours) was given to 22 students of the 7th semester of Agronomy and two Ecuatorian agronomists (with AID scholarships). A set of knowledge evaluation instruments was applied at the beginning and at the end of the course. A total of 83.3% of the students passed the final examination (with more than 75% of correct answers). The difference between the initial and final performance was highly significant (p less than 0.001). According to the students' and teachers' opinions, the general textbook and the teachers book contributed effectively to meet the learning objectives whereas the students handbook needed some modifications. In conclusion, the program is an important contribution to the education of agronomists in a new conception of their role in regard to improvement of the nutritional status and quality of life of the rural population. With a few minor modifications, a final version to be used in the countries of the Region, shall soon become available.

    In this work, the optical measurement system employed to evaluate the performance of a 6 degrees of freedom (dof) positioning mechanism under cryogenic conditions is explored. The mechanism, the flight model of three translations and three rotations positioning mechanism, was developed by the Spanish company SENER (for ASTRIUM) to fulfil the high performance requirements from ESA technology preparatory program for the positioning of a secondary mirror within the GAIA Astrometric Mission. Its performance has been evaluated under vacuum and temperature controlled conditions (up to a 10-6mbar and 100K) at the facilities of the Space Instrumentation Laboratory (LINES) of the Aerospace Technical Nacional Institute of Spain (INTA). After the description of the 'alignment tool' developed to compare a fixed reference with the optical signal corresponding to the movement under evaluation, the optical system that allows measuring the displacements and the rotations in the three space directions is reported on. Two similar bread-boards were defined and mounted for the measurements purpose, one containing two distancemeters, in order to measure the displacements through the corresponding axis, and an autocollimator in order to obtain the rotations on the plane whose normal vector is the axis mentioned before, and other one containing one distancemeter and one autocollimator. Both distancemeter and autocollimator measurements have been combined in order to extract the information about the accuracy of the mechanism movements as well as their repeatability under adverse environmental conditions.

    Full Text Available Wheat scab is common in Argentina mainly durum wheat and some bread varieties. The epidemics occur every 5 to 7 years. During the 2007, 2008, and 2009 growing seasons, three trials were conducted at the INTA Balcarce Experimental Station. Each plot had six rows of 5 m long, spaced 0.15 m apart and was set up in a randomized complete block design with four replications. Trifloxystrobin plus cyproconazole was sprayed at Z3.1 stage. Treatments were sprayed at Z6.1 stage with tebuconazole, prochloraz, and metconazole to improve scab control. Artificial inoculations were made in Z6.1. Severity of Septoria leaf bloth and leaf rust was assessed in boot stage (Z3.9. Scab severity was rated at early dough stage (Z8.3. Yields were recorded each year. Fungicide only applied at Z3.1 stage did not reduce field scab severity but reduced the seeds infection and increased the yields. Early fungicide spray produced yield increase at about 22% and a decrease in seed infection of up to 40%. Yields increased in a 55.3% and in a 19.6% when compared with the inoculated and not inoculated check, respectively. The purpose of this study was to evaluate the effect of foliar disease control on scab, crop yield, and seed health.

    We present an advanced, VO-compliant version of Clusterix, a tool for the determination of membership probabilities in stellar clusters from proper motion data. Clusterix is a web-based, interactive application that allows the computation of membership probabilities from proper motions through a fully non-parametric method. Version 1.0 (http://clusterix.cerit-sc.cz/) was developed as a collaboration between the Masaryk University (Czech Republic) and the Universitat de Barcelona (Spain), as a complement to the WEBDA (http://webda.physics.muni.cz) database of observational data on stars in open clusters. Clusterix 2.0 (http://clusterix.cab.inta-csic.es/clusterix/) is oriented towards the exploitation of Gaia data products. With the participation of the Spanish Virtual Observatory, Clusterix now features an improved user interface for a faster, easier and more accurate interactive definition of the cluster and field proper motion distributions. The system provides fast feedback between membership probability determinations and the distribution of observables for the most probable members and field stars, with graphic tools to display, for instance, photometric diagrams on the fly. Furthermore, Clusterix 2.0 is fully VO-compatible, what opens interesting prospects for the astrophysical exploitation of the improved membership probabilities that will be capable to provide for many open clusters observed by Gaia.

    Full Text Available Background: Seizures are very common in pediatric patients. As duration of seizures impacts morbidity and mortality to child’s life, control of seizures should be achieved as early as possible, preferably at home. Rectal diazepam and intranasal midazolam are available methods for control of seizures and can be learnt by parents. Methods: We assessed safety and efficacy of intranasal midazolam for control of seizures and also compared its effect with other benzodiazepines given by intravenous route. Results: Among 84 patients, success rate of treatment with Midazolam (intranasal was 45.5% and success rate with Benzodiazepines (intravenous was 90%. The difference is statistically significant. In present study, average time recorded to give drug after arrival at hospital in IN Midazolam group was 0.379 min, where as it was 1.598 min in IV Benzodiazepine group. Average time for cessation of seizures after giving drug was 3.001 min in IN Midazolam group, where as it was 1.009 min in IV Benzodiazepine group. Conclusion: Intra-venous route for control of seizures is most effective compare to Inta-nasal Midazolam. However intranasal Midazolam can be use full when IV access is not available at home or during transport of patient to health care centre. [Natl J of Med Res 2013; 3(1.000: 30-33

    Spiders have considerable potential importance for their role as predators to some pests in agricultural systems. The composition of spiders in transgenic and conventional cotton at the Research Station of INTA Reconquista (Santa Fe) was studied during the 2005-2006 season. The experiment was a complete randomized block design with three replications and three treatments: transgenic Bt cotton (ALBt), conventional cotton without chemical control (ALCSC), and conventional cotton with chemical control (ALCCC). Weekly, spiders were collected using nets, vertical cloth and pitfall-traps. A total of 1255 specimens (16 families, and 32 species) were collected. Seven families were found in all the treatments, mainly Thomisidae (n=1 51, 84.04%) and Araneidae (n=83, 6.64%). The Hunting spiders guild ambushers (n=1053, 83.91%), "Orb weavers" (n=85, 6.77%) and "Stalkers" (n=53, 4.22%) were more abundant. There were no significant differences in the indexes diversity between treatments. Spiders were presented during the whole crop season, with peaks about flowering and boll maturity, with the highest abundance in ALBt. This work is part of the first set of data registered in Argentina about spider's community in cotton crops.

    Synechocystis sp. PCC 6803 is a genetically tractable model organism for photosynthesis research. The genome of Synechocystis sp. PCC 6803 consists of a circular chromosome and seven plasmids. The importance of small regulatory RNAs (sRNAs) as mediators of a number of cellular processes in bacteria has begun to be recognized. However, little is known regarding sRNAs in Synechocystis sp. PCC 6803. To provide a comprehensive overview of sRNAs in this model organism, the sRNAs of Synechocystis sp. PCC 6803 were analyzed using deep sequencing, and 7,951,189 reads were obtained. High quality mapping reads (6,127,890) were mapped onto the genome and assembled into 16,192 transcribed regions (clusters) based on read overlap. A total number of 5211 putative sRNAs were revealed from the genome and the 4 megaplasmids, and 27 of these molecules, including four from plasmids, were confirmed by RT-PCR. In addition, possible target genes regulated by all of the putative sRNAs identified in this study were predicted by IntaRNA and analyzed for functional categorization and biological pathways, which provided evidence that sRNAs are indeed involved in many different metabolic pathways, including basic metabolic pathways, such as glycolysis/gluconeogenesis, the citrate cycle, fatty acid metabolism and adaptations to environmentally stress-induced changes. The information from this study provides a valuable reservoir for understanding the sRNA-mediated regulation of the complex physiology and metabolic processes of cyanobacteria.

    Full Text Available The incident solar radiation on soil is an important variable used in agricultural applications; it is also relevant in hydrology, meteorology and soil physics, among others. To estimate this variable, empirical models have been developed using several parameters and, recently, prognostic and prediction models based on artificial intelligence techniques such as neural networks. The aim of this work was to develop linear models and neural networks, multilayer perceptron, to estimate daily global solar radiation and compare their efficiency in its application to a region of the Province of Salta, Argentina. Relative sunshine duration, maximum and minimum temperature, rainfall, binary rainfall and extraterrestrial solar radiation data for the period 1996-2002, were used. All data were supplied by Experimental Station Salta, Instituto Nacional de Tecnología Agropecuaria (INTA, Argentina. For both, neural networks models and linear regressions, three alternative combinations of meteorological parameters were considered. Good results with both prediction methods were obtained, with root mean square error (RMSE values between 1.99 and 1.66 MJ m-2 d-1 for linear regressions and neural networks, and coefficients of correlation (r² between 0.88 and 0.92, respectively.

    A research project for producing plants by cuttings propagation is being carried out by the National Institute of Agrarian Technology (Instituto Nacional de Tecnologia Agropecuaria (INTA)). The cuttings propagation technique consists of taking a part of a mother plant (cutting) and putting it in adequate conditions to induce the formation of roots. It is composed of two main stages: the first is conducted under controlled conditions and the second one is to rusticate and acclimatize rootstocks in a half-shadowed protected area. Because of the change of environment for the rootstocks, this technique has a problem of a low percentage of survival. In this paper the facilities and the working of a special greenhouse to rusticate is described in order to allow an appropriate acclimatization before the rootstocks be transferred to the second stage and to secure higher levels of survival. This greenhouse has a double plastic cover and below the second roof it has a aluminum half-shadowed folding curtain. The heating systems for both the greenhouse and hotbed is completed with plastic exchanger-collectors placed on northern and southern sides and an outdoor packed bed. The thermal behavior of the greenhouse, the different elements used and the routine of working are analyzed. The behaviour of the special greenhouse was between the foreseen levels, showing an important decrease of convective and radiative losses and the packed bed an exchangers - collectors gave an adequate amount of energy to the system.

    Full Text Available Normas, procedimentos de ensaio e trabalhos de pesquisa apontam a regularidade de distribuição longitudinal de sementes como uma das características operacionais de semeadoras que mais contribuem para a obtenção de um stand adequado de plantas e, conseqüentemente, boa produtividade. Dois parâmetros são utilizados para essa avaliação: o coeficiente de variação (CV das populações de espaçamentos e as porcentagens de ocorrência de espaçamentos aceitáveis ou de sementes "normalmente semeadas". Como tais textos preconizam o emprego de diferentes procedimentos para o cálculo daqueles parâmetros de avaliação, o presente estudo visou aos efeitos dos diferentes tratamentos de dados nos resultados e na sua interpretação. Aplicaram-se tratamentos - DEA, ISO, ABNT e INTA ADAPTADO - às populações de espaçamentos de sementes, resultantes de ensaios de bancada com três tipos de mecanismos desadores (disco horizontal, disco inclinado e disco vertical com dispositivo pneumático. Para dois deles, observaram-se diferenças expressivas entre os resultados da aplicação dos tratamentos, tanto no tocante aos coeficientes de variação (CV quanto às ocorrências de espaçamentos definidos como aceitáveis. Dependendo do tratamento, corre-se o risco, num processo de avaliação de desempenho, de aprovar-se um mecanismo que, como máquina, apresenta resultados satisfatórios, sem, no entanto, atender aos requisitos agronômicos, sua função básica.Standards, test procedures and research works appoint the regularity of seed longitudinal distribution as one of the seed drills operational characteristics that contributes for attainment of an adequate plant stand and good productivity.

    Full Text Available Currently, family farming has taken visibility both in academic works and in the design of public policies. Even though are recognized own characteristics which differentiate it from the business production, they are presented according to the type of production and the territory where they are inserted, particularities that allow defining and analyzing them. In the case of family horticultural and flower production, which supplies with fresh products to big urban centers, the specificity of labor-intensive production system, the technologies utilized, the characteristics of the obtained products, their commercialization and their localization, differs substantially from others productive systems of the country. According to diagnosis made by INTA [2004] and other qualitative works in suburbs of Buenos Aires, the difficulties faced by these households are multiples. Among the most important are mentioned the subordination in the commercial chain and the access to financing. This paper seeks account for a territorial development project in the peri-urban region of Gran La Plata, which addresses from an integral perspective, to financing aspects and commercialization to family farmers It focuses on 30 family farmers from La Plata and Berazategui belonging to the project "Banco Social", implemented by Facultad de Ciencias Agrarias y Forestales from UNLP; advancing on an analysis regarding the access to financing and the commercial strategies carried out by the family farmers under studyEn la actualidad, la agricultura familiar ha tomado visibilidad tanto en trabajos académicos como en el diseño de políticas públicas.

    Measurements of the vertical atmospheric electric field (Ez) made at auroral station Apatity (geomagnetic latitude: 63.8) and polar cap station Vostok, Antarctica (geomagnetic latitude: -89.3) in 2001-2002 have been analyzed. The measurements were made by a high-latitude computer-aided complex installed at Apatity in 2001. It consists of three spatially placed microbarographs for measurements of atmospheric waves, a device for air conductivity measurement and a device for measurement of vertical component of the atmospheric electric field. The computer-aided system permits to get information with a frequency of five times per second. The ground level atmospheric electric field was found to have systematic local diurnal and seasonal variations. Diurnal variations of atmospheric potential gradient were found to have a departure from the Carnegie curve. A distinct difference in the diurnal variation of atmospheric electric field has been observed also between disturbed (Kp>30) and extremely quiet (Kplatitude electric field variations appear to be the result of solar wind-magnetosphere-ionosphere coupling. Besides, we have found the similarity between the diurnal course of the atmospheric electric field under the quiet geomagnetic conditions and the diurnal variation of galactic cosmic rays. These results have been explained in terms of calculated effective Bz component of the interpalnetary magnetic field arising due to variation of the geomagnetic dipole axis inclination during the Earth's rotation. The results of analysis of the influence of extreme weather conditions (rain, snow, snowstorm, stormclouds, thunderstorms, lightning) on atmospheric electricity (electric field and conductivity) are also discussed.

    PCBs were discovered in the Lake Baikal ecosystem by Malakhov et al. and Bobovnikova et al. A follow up to the initial study showed no decrease over 1981-1989 4, in contrast to what has been observed in other water bodies in the industrialised world. Further studies also showed the contamination in pinnipeds to be among the highest measured anywhere. Above studies and other data suggested a presence of a strong local PCB source (or several ones), which has had a widespread adverse effect for the whole region. To locate the source, Mamontov et al. collected samples from 34 sites over the region, the analysis of which showed a gradient of a factor of 1000, with the lowest concentrations at the north-east of Lake Baikal and the highest concentrations close to the city of Usolye Sibirskoye, a centre of the chemical industry in the Angara River valley. A continuous decrease in the soil contamination was observed along the path from Usolye Sibirskoye up the Angara River valley to Lake Baikal and from there north-eastward along the lake. These results indicate that there was (and perhaps still is) a major source of PCBs in the Usolye area, from where the PCBs are dispersed over the region. However, various obstacles prevent direct observations of potential sources. Therefore, a mathematical modelling approach was adopted in a currently ongoing INTAS project aiming to shed some more light on this problem. The model principles, setup and the results of the first experiments are presented in the current paper.

  19. Meiotic abnormalities underlying pollen sterility in wild potato hybrids and spontaneous populations.

    Wild potato species are widely distributed in the Americas, where they spontaneously grow in very diverse habitats. These species - with low chromosome differentiation - form polyploid series with 2n = 2x, 3x, 4x and 6x (x =12). They are isolated in nature by external and internal hybridisation barriers that can be incomplete, allowing hybridisation in areas of sympatry. Nevertheless, most accessions in germplasm banks, regardless of genetic background of the sampled spontaneous populations, have been assigned specific categories based on morphological characters. To further investigate the extent of hybridisation in the group and for comparative purposes, pollen viability was estimated in (i) artificial hybrids between a commercial cultivar (Calén INTA) of the common potato (tetraploid Solanum tuberosum ssp. tuberosum) and the tetraploid cytotype of the related wild species S. gourlayi, and (ii) samples of plants (accessions) and inflorescences of natural populations from Argentina, tentatively classified as 'presumed hybrids' (S. infundibuliforme-S. gourlayi) and 'species' (S. infundibuliforme, S. gourlayi and S. chacoense). Regardless of origin, 98 out of 103 plants analysed had zero to 70% pollen viability (zero to 40% in eight of them). Pollen grains were of variable size and morphology and, in mostly male sterile plants, the only viable pollen grains were 2n and/or 4n. Furthermore, male sterile plants shared various abnormalities in meiosis I and II (unpaired chromosomes, unequal chromosome distribution, precocious/lagging chromosomes, parallel, tripolar, fused and multiple spindles, unequal size nuclei, dyads, triads and pentads in addition to normal tetrads, among others). These results provide novel evidence to support field observations of early potato botanists on the extent of spontaneous hybridisation in wild Argentinian potato populations, which is not reflected in the current taxonomy and has significant consequences for germplasm conservation and

    The lack of accuracy in the knowledge of cloud microphysics leads to aviation risks, which have caused numerous crashes, mainly owing to aircraft icing (e.g., an EMB-120 crashed in Detroit, Michigan in 1997, and an ATR-72 crashed near Roselawn, Indiana in 1994). Further, this lack is a source of uncertainty in numerical weather forecasting models, since commonly used parameterizations often overestimate ice water content and underestimate supercooled liquid water. This makes the collection of data on cloud microphysical characteristics very useful toward improving the forecasting of icing conditions. Ten research flights were conducted during the winters of 2011/12 and 2012/13. Their goal was to determine dominant microphysical conditions of winter cloud systems traversing the Guadarrama Mountains in the central Iberian Peninsula. The aircraft was a C-212-200, equipped with a Cloud, Aerosol, and Precipitation Spectrometer (CAPS) under the left wing. Data of temperature and Liquid Water Content (LWC), registered by the CAPS probe, were used in the study. Furthermore, we thoroughly analyzed images taken by a Cloud Imaging Probe Grayscale (CIP-GS), capable of measuring hydrometeors between 25 and 1,550 µm in size, and representing them in a 2D image. The various types of hydrometeors observed during these flights are described, along with microphysical processes inferred from the CIP-GS images. ACKNOWLEDGEMENTS S.

    Metamorphosed volcano-sedimentary rocks accreted to the northern South American continental margin are major vestiges of the Caribbean oceanic plate evolution and its interactions with the continent. Selected whole rock geochemistry, Nd-Sr isotopes and detrital zircon geochronology were obtained in metabasic and metasedimentary rocks from the Santa Marta and San Lorenzo Schists in northernmost Colombia. Trace element patterns are characterized by primitive island arc and MORB signatures. Similarly initial 87Sr/ 86Sr-ɛ Nd isotopic relations correlate with oceanic arcs and MORB reservoirs, suggesting that the protoliths were formed within a back-arc setting or at the transition between the inta-oceanic arc and the Caribbean oceanic crust. Trace element trends from associated metasedimentary rocks show that the provenance was controlled by a volcanic arc and a sialic continental domain, whereas detrital U/Pb zircons from the Santa Marta Schists and adjacent southeastern metamorphic units show Late Cretaceous and older Mesozoic, Late Paleozoic and Mesoproterozoic sources. Comparison with continental inland basins suggests that this arc-basin is allocthonous to its current position, and was still active by ca. 82 Ma. The geological features are comparable to other arc remnants found in northeastern Colombia and the Netherland Antilles. The geochemical and U/Pb detrital signatures from the metasedimentary rocks suggest that this tectonic domain was already in proximity to the continental margin, in a configuration similar to the modern Antilles or the Kermadec arc in the Pacific. The older continental detritus were derived from the ongoing Andean uplift feeding the intra-oceanic tectonic environment. Cross-cutting relations with granitoids and metamorphic ages suggest that metamorphism was completed by ca. 65 Ma.

Esto significa que debemos comprender qué le sucede a un pesticida que ha sido aplicado en el campo, y predecir su destino en el ambiente. Con este objetivo se estudió una parcela experimental del Instituto Nacional de Tecnología Agropecuaria (INTA en la localidad de Manfredi (Córdoba; Argentina. Se realizaron mediciones del contenido de agua en suelo (por sonda de neutrones y por el método gravimétrico y la precipitación ocurrida en el sitio durante un período de tiempo con el fin de modelar el proceso de humedecimiento. También se midieron los contaminantes a distintas profundidades y a distintos tiempos de aplicación de atrazina al predio. Con estos datos se buscó modelar el proceso con el programa HYDRUS. Los resultados obtenidos muestran que el modelo subestima los contenidos de humedad presentes en el horizonte superior, mientras que para profundidades mayores frente a eventos de precipitaciones normales y de riego, el frente de humedecimiento no genera una recarga directa de la freática. Los resultados obtenidos muestran que la simulación numérica resulta una herramienta válida para el estudio del movimiento del flujo y el transporte de sustancias contaminantes en la zona no saturada. La principal limitante para evaluar la validez de estos modelos son la poca disponibilidad de datos de estudios de campo.

    The solutions for the Hasselmann equation (kinetic equation for wind-driven waves) are studied numerically for the case of duration-limited growth and different conventional parameterizations of wave sources and sinks (Snyderet al. 1981; Plant 1982; Hsiao &Shemdin 1983; Komen, Hasselmann & Hasselmann 1984; Donelan, Pierson 1987). The strong self-similar behavior of the numerical solutions is found for all the parameterizations in a wide range of wind speeds and wave ages. Moreover, the resulting self-similar solutions are found to be surprisingly close to experimentally established approximations in magnitudes and shapes of frequency spectra. The comparison with JONSWAP modified spectra (Donelan et al. 1985) is detailed. It is found that this approximation being obtained for the case of fetch-limited growth fits quite well the corresponding spectra for the numerical duration limited solutions in a wide range of wave ages (C_p/U10 ≈ 0.4div 1.4 ). Theoretical overview of self-similar solutions for the kinetic equation is given in its relation to the experimentally observed dependencies of mean parameters (i.e. mean energy, frequency) of wind-driven waves both in cases of fetch-limited and duration limited growth. Universality features of the dependencies are treated as a result of dominating nonlinear transfer in wind-wave field.

    HARMONI (High Angular Resolution Monolithic Optical and Near-infrared Integral field spectrograph) is a visible and near-infrared (0.47 to 2.45 μm) integral field spectrograph selected as a first-light instrument for the European Extremely Large Telescope (E-ELT). With four spatial scales (60, 20, 10 and 4 mas) and a wide range of spectral resolving powers (R=3500, 7500, 20000), HARMONI will allow scientists to address many of the E-ELT science cases. The HARMONI Consortium is led by the University of Oxford, and is also formed by the UK Astronomy Technology Centre (UKATC, Edinburgh, UK), Centre de Recherche Astrophysique de Lyon (CRAL), Laboratoire d'Astrophysique de Marseille (LAM), Instituto de Astrofísica de Canarias (IAC, Spain) and the Centro de Astrobiología (CAB INTA-CSIC, Spain). We summarize here the current status of the project, and describe the participation of CAB to design and manufacture two of the instrument sub-systems: the calibration unit and the secondary guiding module. The calibration unit will simulate the optical output of the telescope, and provide the functionality needed to illuminate the focal plane in such a way that the following type of data can be obtained: data aimed at removing the instrumental signature from the raw data and to convert the data into a data product that uses physical units, data required for monitoring the status of the instrument, and data required for calibrating the secondary guiding subsystem. The secondary guiding subsystem basic requirement is to provide knowledge (relative or absolute) of the location of the science focal plane on timescales of a few seconds and longer (up to months), with an accuracy of 2mas or 0.1x the input FWHM (at H/K bands), whichever is greater. The subsystem should achieve this level performance for different observation modes, e.g. no- AO, GLAO and LTAO modes.

    Aim of the study: to analyze, within a Pinus contorta plantation, the effects of artificially created small rectangular and small medium circular canopy gaps on: i) photosynthetic active radiation (PAR), and soil temperature and moisture, and ii) survival and growth of planted Austrocedrus chilensis and Nothofagus dombeyi seedlings, species which formerly composed the natural forest of the area. Study area: A 2 ha stand of a Pinus contorta stand in Los Alerces National Park, Argentina (42°43’S, 71°43’W, 490 m.a.s.l.). Material and methods: The Pinus contorta stand was 25 yr old, 22 m height and 26 cm DBH, presenting 1000 trees ha-1 of density and 53 m2 ha-1 of basal area. In 2009, rectangular and circular gaps were created within the stand and then seedlings were planted. During two growing seasons (2010-2011 and 2011-2012), PAR, soil temperature and moisture were measured in gaps and understory (control), and seedling survival and growth in gaps. Main results: During both seasons, soil temperature did not differ among gaps and control, whereas PAR and soil moisture were lower in control than in gaps. Seedling survival was high in all gaps regardless of species and season. Seedlings showed higher diameter growth in rectangular than in circular gaps. Research highlights: Austrocedrus chilensis and N. dombeyi seedlings survival is high and their growth slightly affected, when planted in differently-sized canopy gaps within a Pinus contorta plantation in Patagonia. However, other gap sizes and stand densities should be tested before recommending which one shows better results for reconverting monocultures into former native forests.

    The use of the soil in the Humid Pampa of Argentina has changed since the mid-1990s from agricultural-livestock production (that included pastures with direct grazing) to a purely agricultural production. Also, in recent years the area under irrigation by central pivot has been increased to 150%. The waters used for irrigation are sodium carbonates. The combination of irrigation and rain increases the sodium absorption ratio of soil (SARs), consequently raising the clay dispersion and reducing infiltration. This implies an increased risk of soil loss. A reduction in the development of white clover crop (Trifolium repens L.) was observed at an irrigation plot during 2015 campaign. The clover was planted in order to reduce the impact of two maize (Zea mays L.) campaigns under irrigation, which had increased soil SAR and deteriorated soil structure. SPOT-5 radiometric normalized difference vegetation index (NDVI) images were used to determine two zones of high and low production. In each zone, four random points were selected for further geo-referenced field sampling. Two geo-referenced measures of effective depth and surface soil sampling were carried out in each point. Texture of soil samples was determined by Pipette Method of Sedimentation Analysis. Data exploratory analysis showed that low production zone had a media effective depth = 80 cm and silty clay loam texture, while high production zone had a media effective depth > 140 cm and silt loam texture. The texture class of the low production zone did not correspond to prior soil studies carried out by the INTA (National Institute of Agricultural Technology), which showed that those soil textures were silt loam at surface and silty clay loam at sub-surface. The loss of the A horizon is proposed as a possible explanation, but further research is required. Besides, the need of a soil cartography actualization, which integrates new satellite imaging technologies and geo-referenced measurements with soil sensors is

    Full Text Available Made in the wake of the 2011 Egyptian Revolution, Inti Mabsoota? is an experimental pedagogical video project that draws upon the emerging mobile esthetics of cell phone filmmaking and public encounters with revolutionary spontaneity. Inspired by the landmark cinéma-vérité film, Chronique d'un été (1960, in which participants ask people on the streets of Paris if they are happy, several of my students at the American University in Cairo became mobile film units, asking people the same innocuous question, “Inta mabsoot?/Inti mabsoota?”—Are you happy? Are you content? This seemingly benign exercise belies a variety of conceptual and methodological frictions, which offered productive pedagogical possibilities. Drawing upon the emergent revolutionary visual culture, this student project complicated both the reductive assessments of the “Arab Spring” as a manifestation of digital democracy and the heavy-handed way that western journalism has tended to address the “Arab Street” as a volatile mob. Using an embodied visual approach allowed students to apprehend modes of lived experience that might not register as political in more normative models, but which nonetheless form the basis of how people live and experience political life. Highlighting the non-representational aspects of the encounter also foregrounds the corporeal and visceral dimensions of the students’ experience. Accordingly, the critical video methods employed elucidate the kinds of affective knowledge produced for those on screen, behind the camera, and viewing from a distance.

The technique was applied to multi-sourced HRS data in order to: (1 verify the at-sensor radiometric calibration and (2 obtain radiometric and atmospheric correction coefficients. Spanning two select study sites along the southeast coast of France, data were collected simultaneously by three airborne sensors (AisaDUAL, AHS and CASI-1500i aboard two aircrafts (CASA of National Institute for Aerospace Technology INTA ES and DORNIER 228 of NERC-ARSF Centre UK. The SVC ground calibration site was assembled along sand dunes near Montpellier and the thematic data were acquired from other areas in the south of France (Salon-de-Provence, Marseille, Avignon and Montpellier on 28 October 2010 between 12:00 and 16:00 UTC. The results of this study confirm that the SVC method enables reliable inspection and, if necessary, in-situ fine radiometric recalibration of airborne hyperspectral data. Independent of sensor or platform quality, the SVC approach allows users to improve at-sensor data to obtain more accurate physical units and subsequently improved reflectance information. Flight direction was found to be important, whereas the flight altitude posed very low impact. The numerous rules and major outcomes of this experiment enable a new standard of atmospherically corrected data based on better radiometric output. Future research should examine the potential of SVC to be applied to super-and-hyperspectral data obtained from on-orbit sensors.

    The present communication records the first determination of the prevalence of footrot in the unexpected situation of the tropical climate of Andhra Pradesh and Tamil Nadu, two states in southern India where the maximum temperature rises to 42 degrees C. In total, 73 outbreaks of footrot in Nellore brown sheep were investigated in 11 districts of Andhra Pradesh and one district of Tamil Nadu during the period March 2009 to March 2011.The overall prevalence of ovine footrot was 15%, with severity scores of 2 to 4 (lesion severity scale 0 to 4). The outbreaks occurred mostly during the rainy season, which is usually from June to December. From a total of 1,050 samples of lesions in naturally infected sheep, 478 (45.5%) were positive for Dichelobacter nodosus. Serogrouping of the isolates revealed six serogroups: A, B, C, E, F and I. Among the positive samples, 448 (93.7%) were a single serogroup and 30 (6.3%) carried a mixed infection with two serogroups. Taking single and mixed infections together, serogroup B was most frequent at 50.4% and was found in all districts, followed by serogroup I in 29.3% of samples, A in 14%, F in 6.7% and C in 5.6%. Serogroup E was detected in only one sample. Serogroups A and F were detected for the first time in India. All of 58 D. nodosus isolates in a sub-sample representing different serogroups were found to be virulent, based on the production of thermostable proteases and the presence of the integrase A gene intA. Thus, the present paper reporting isolation and characterisation of D. nodosus confirms the occurrence of virulent footrot in the tropical climate of southern India.

Conversely, the fast and sustained antidepressant effect of the N-methyl-d-aspartate receptor (NMDAR antagonist ketamine raises vast interest in understanding the role of the glutamate system in mood disorders. Indeed, numerous data support the existence of glutamatergic dysfunction in major depressive disorder (MDD. Drawback to this short-latency therapy is its side effect profile, especially the psychotomimetic action, which seriously hampers the common and widespread clinical use of ketamine. Therefore, there is a substantial need for alternative glutamatergic antidepressants with milder side effects. In this article, we review evidence that implicates NMDARs in the prospective treatment of MDD with focus on rapastinel (formerly known as GLYX-13, a novel synthetic NMDAR modulator with fast antidepressant effect, which acts by enhancing NMDAR function as opposed to blocking it. We summarize and discuss current clinical and animal studies regarding the therapeutic potential of rapastinel not only in MDD but also in other psychiatric disorders, such as obsessive–compulsive disorder and posttraumatic stress disorder. Additionally, we discuss current data concerning the molecular mechanisms underlying the antidepressant effect of rapastinel, highlighting common aspects as well as differences to ketamine. In 2016, rapastinel received the Breakthrough Therapy designation for the treatment

    The investigation of climatic changes in the past and their possible reasons is a complicated problem. The content of radio- and stable isotopes measured in dated samples is a well developed and widely recognized tool for studying changes in the Earth's and near-Earth's environments on a long time scale. From the other hand the biological systems themselves can serve as an indicator of changes in natural conditions. One of quantitative parameters characterizing shifts in surrounding nature might be the absolute value of annual tree growth. In the present work the data of tree ring widths taken from the northern part of Russia together with the content of O-18 and Be-10 in Greenland ice are investigated. The most significant periods in tree ring growth correspond to quasi 200 year and century-scale variations - the solar cycles of Suess and Gleissberg. The variations in tree ring as well as the variations of stable isotopes in ice cores suggest the connection between solar and climate variability. In the beginning of 20th century the break in cyclic behavior for some of the considered samples was discovered. The possible impact of Tunguska meteorite as well as changes of global temperature on the tree growth is discussed. The variability in O-18 content and characteristic cycles in Be-10 series will be compared. There is a possibility of solar energetic particles producing during large solar flares to influence the climatic conditions on the Earth. V.D., M.O., and O.R. thank INTAS for partial support.

    Low molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their complex protein banding patterns in SDS-PAGE and tight linkage with gliadins at the Gli-1 locus. Using DNA markers and a backcross program we developed a set of nine near isogenic lines (NILs) including different Glu-A3/GliA-1 or Glu-B3/Gli-B1 alleles in the genetic background of the Argentine variety ProINTA Imperial. The nine NILs and the control were evaluated in three different field trials in Argentina. Significant genotype-by-environment interactions were detected for most quality parameters indicating that the effects of the Glu-3/Gli-1 alleles are modulated by environmental differences. None of the NILs showed differences in total flour protein content, but relative changes in the abundance of particular classes of proteins cannot be ruled out. On average, the Glu-A3f, Glu-B3b, Glu-B3g and Glu-B3iMan alleles were associated with the highest values in gluten strength-related parameters, while Glu-A3e, Glu-B3a and Glu-B3iChu were consistently associated with weak gluten and low quality values. The value of different Glu3/Gli-1 allele combinations to improve breadmaking quality is discussed.

    We are developing a new kind of planetary exploration mission for Mars - MetNet in situ observation network based on a new semi-hard landing vehicle called the Met-Net Lander (MNL). The key technical aspects and solutions of the mission will be discussed. The eventual scope of the MetNet Mission is to deploy some 20 MNLs on the Martian surface using inflatable descent system structures, which will be supported by observations from the orbit around Mars. Currently we are working on the MetNet Mars Precursor Mission (MMPM) to deploy one MetNet Lander to Mars in the 2009/2011 launch window as a technology and science demonstration mission. The MNL will have a versatile science payload focused on the atmospheric science of Mars. Detailed characterization of the Martian atmospheric circulation patterns, boundary layer phenomena, and climatology cycles, require simultaneous in-situ measurements by a network of observation posts on the Martian surface. The scientific payload of the MetNet Mission encompasses separate instrument packages for the atmospheric entry and descent phase and for the surface operation phase. The MetNet mission concept and key probe technologies have been developed and the critical subsystems have been qualified to meet the Martian environmental and functional conditions. This development effort has been fulfilled in collaboration between the Finnish Meteorological Institute (FMI), the Russian Lavoschkin Association (LA) and the Russian Space Research Institute (IKI) since August 2001. Currently the INTA (Instituto Nacional de Técnica Aeroespacial) from Spain is also participating in the MetNet payload development.

    Glyphosate is a worldwide used herbicide as c. 90% of transgenic crops are tolerant to it. Microbial degradation of glyphosate molecule in soil is considered the most important process that determines its persistence in the environment. However, the impact of this herbicide on target groups of soil biota remains poorly understood. Our objective was to characterize the abundance of bacterial groups and global microbial activity, under controlled conditions with application of increasing doses of glyphosate. A bioassay was carried out in microcosms using an agricultural soil (Typic Argiudoll) with registered history of glyphosate application from National Institute of Agricultural Technology (INTA, EEA Marcos Juarez, Argentina). Glyphosate of commercial formulation (74.7%) was used and the following treatments were evaluated: Soil without glyphosate (control), and Soil with doses equivalent to 1.12 and 11.2 kg ai ha-1. Microbiological parameters were estimated at 3, 7, 14 and 21 days after herbicide application by counting heterotrophic, cellulolytic, nitrogen fixing (N), and nitrifying bacteria; and fluorescein diacetate hydrolysis (FDA), microbial respiration (MR) and microbial biomass (C-BM). The N cycle related bacteria showed greater sensitivity to glyphosate with significant increases in abundance. On the other hand the C cycle parameters were strongly conditioned by the time elapsed since the application of the herbicide, as did the MR. The FDA declined with the highest dose, while the C-BM was not affected. Therefore, we conclude that in the studied experimental conditions glyphosate stimulated bacterial growth (i.e. target abundances) representing a source of N, C and nutrients. On the other hand, enzymatic activity (FDA) decreased when glyphosate was applied in the highest dose, whereas, it had no effect on the MR nor C-BM, which could be attributable to the organic matter content of the soil. However, future research in field conditions is necessary, for

    The possibility of Evpatoria RT-70 planetary radar application for space debris research was tested in two trial experiments for targets at geostationary (GEO) and high-elliptic (HEO) orbits in 2001. The RT-70 has the 200 kW continuous power transmitter at 6-cm wavelength, which was used for radio location of planets. Therefore the bistatic radar system only may be realized for orbital object measurements. The receiving antennas (Bear Lakes RT-64, Svetloe RT-32, Noto RT- 32, Torun RT-32 and Urumqi RT-25) used the standard VLBI equipment for recording of echo-signals, because they have not specialized radar apparatus. Such multi-antennas configuration allows to add the classic radar data with VLBI measurements: radar has the resolution for range and radial velocity, VLBI provides the angle and angular rate. Moreover the VLBI radar may be a tool for 3D- measurements: combination of radar map and VLBI image can result the "radio holography" picture of investigated object. Seven GEO objects were detected in May session and four GEO + two HEO objects - in December session. The uncontrolled axial rotation with 5 - 20 s period was fixed for GEO targets. The first results of processing that carry out at Russia and Canada are presented. It is planned to finally adjust the VLBI radar method and t o start the regular observations under the international program of optical and radar monitoring of the near-Earth space environment that will be partially supported by INTAS-01-0669, RFBR-02-02- 17568 and RFBR-02-02-3108.

    We present developing of methods (e.g., Dorman et al., 1995, 1999) for forecasting on the basis of neutron monitor hourly on-line data (as well as on-line muon telescopes hourly data from different directions) geomagnetic storms of scales G5 (3- hour index of geomagnetic activity Kp=9), G4 (Kp=8) and G3 (Kp=7) (according to NOAA Space Weather Scales). These geomagnetic storms are dangerous for people technology and health (influence on power systems, on spacecraft operations, on HF radio-communications and others). We show that for especially dangerous geomagnetic storms can be used global-spectrographic method if on-line will be available 35-40 NM and muon telescopes. In this case for each hour can be determined CR anisotropy vector, and the specifically behavior of this vector before SC of geomagnetic storms G5, G4 or G3 (according to NOAA Space Weather Scales) can be used as important factor for forecast. The second factor what can be used for SC forecast is specifically behavior of CR density (CR intensity) for about 30-15 hours before SC (caused mainly by galactic CR particles acceleration during interaction with shock wave moved from the Sun). The third factor is effect of cosmic ray pre-decreasing, caused by magnetic connection of the Earth with the region behind the shock wave. We demonstrate developing methods on several examples of major geomagnetic storms. This research is partly supported by the INTAS grant 00-0810. REFERENCES: Dorman L.I., et al.

    According to NOAA Space Weather Scales, geomagnetic storms of scales G5 (3- hour index of geomagnetic activity Kp=9), G4 (Kp=8) and G3 (Kp=7) are dangerous for people technology and health (influence on power systems, on spacecraft operations, on HF radio-communications and others). To prevent these serious damages will be very important to forecast dangerous geomagnetic storms. In many papers it was shown that in principle for this forecasting can be used data on CR intensity and CR anisotropy changing before SC of major geomagnetic storms accompanied by sufficient Forbush-decreases (e.g., Dorman et al., 1995, 1999). In this paper we consider over 100 major geomagnetic storms and for each case we analyze hourly data of many NM for 8 days with SC in the 4-st day of 8 days period (so before SC we have at least 3 full days). We- determine what part of major geomagnetic storms is accompanied CR intensity and CR anisotropy changing before SC, and what part of major geomagnetic storms does not show any features what can be used for forecasting. We estimate also how these parts depend from the index of geomagnetic activity Kp. This research is partly supported by the INTAS grant 00-0810. REFERENCES: Dorman L.I., et al.

    Full Text Available Synechocystis sp. PCC 6803 is a genetically tractable model organism for photosynthesis research. The genome of Synechocystis sp. PCC 6803 consists of a circular chromosome and seven plasmids. The importance of small regulatory RNAs (sRNAs as mediators of a number of cellular processes in bacteria has begun to be recognized. However, little is known regarding sRNAs in Synechocystis sp. PCC 6803. To provide a comprehensive overview of sRNAs in this model organism, the sRNAs of Synechocystis sp. PCC 6803 were analyzed using deep sequencing, and 7,951,189 reads were obtained. High quality mapping reads (6,127,890 were mapped onto the genome and assembled into 16,192 transcribed regions (clusters based on read overlap. A total number of 5211 putative sRNAs were revealed from the genome and the 4 megaplasmids, and 27 of these molecules, including four from plasmids, were confirmed by RT-PCR. In addition, possible target genes regulated by all of the putative sRNAs identified in this study were predicted by IntaRNA and analyzed for functional categorization and biological pathways, which provided evidence that sRNAs are indeed involved in many different metabolic pathways, including basic metabolic pathways, such as glycolysis/gluconeogenesis, the citrate cycle, fatty acid metabolism and adaptations to environmentally stress-induced changes. The information from this study provides a valuable reservoir for understanding the sRNA-mediated regulation of the complex physiology and metabolic processes of cyanobacteria.

    Previously we had shown possibility of long-term cultivation of wheat and radish uneven-aged conveyer on the soil-like substrate (SLS) with periodic introduction in the SLS of edible (in the form of a mineral solution after physicochemical burning) and inedible biomass of the plants grown on it. The given work was aimed at the study of production characteristics of the plants cultivated on the SLS with a periodic introduction of plant biomass, which consisted of harvested inedible biomass and wheat straw. The wheat straw was introduced in the SLS to compensate carrying out of mineral elements from the SLS with the edible biomass of the harvested plants. Also possibility of joint cultivation of the chosen vegetable plants under the given way of plant inedible biomass introduction in the SLS was estimated. Chufa (Cyperus esculentus L.), radish (Raphanus sativus L.) and lettuce (Lactuca sativa L.) were taken as the objects of research. Plants were grown in the regime of the three-species uneven-aged conveyer. Before each next planting of plants we introduced in the SLS all inedible biomass of earlier harvested plants and wheat straw. The amount of introduced wheat straw depended on nitrogen content in edible biomass of the harvested plants. Plants irrigation was performed by means of common nutrient solution containing mineral elements extracted from the SLS. 2 concentration in a vegetation chamber was maintained in limits from 0.1The work was carried out under support of SB RAS grant 132 and INTAS grant 05-1000008-8010

    Full Text Available El carcinoma mucoepidermoide de glándula salival es un tumor frecuente; constituye el 15% de los tumores de dicha estructura. Sin embargo, en la mandíbula son mucho menos frecuentes (menos de 200 casos reportados y se le conoce como carcinoma mucoepidermoide central. La patogenia de este tumor intraóseo sigue siendo controversial. Al igual que otros carcinomas intaóseos primarios, puede tener varios orígenes: 1 atropamiento de glándulas mucosas retromolares en la mandíbula, 2 epitelio del seno maxilar, 3 atropamiento iatrogénico de glándula salival menor (ej. en una osteomielitis o sinusitis crónica, 4 remanentes de lámina dental, 5 remanentes de tejido de glándula salival en la mandíbula, 6 transformación neoplásica de células mucosecretoras en el epitelio de revestimiento de quistes odontogénicos. Se presenta el caso de un hombre con un carcinoma mucoepidermoide central de la mandíbula y se hace una revisión del tema.Mucoepidermoid carcinomas of the salivary glands are frequent lesions that account for 15% of all salivary gland tumors, they are very infrequent in the mandible, with less than 200 cases reported and known as central mucoepidermoide carcinoma. The pathogenesis of this intraosseous tumor is still controversial. Several theories of their pathogenesis have been postulated: 1 entrapment of retromolar mucous glands within the mandible, 2 maxilla sinusepithelium, 3 iatrogenic entrapment of minor salivary glands (chronic osteomielitis or sinusitis, 4 dental lamina remnants, 5 developmentally included embryonic remnants of submandibular glands within the mandible, 6 neoplastic transformation of mucus-secreting cells in the epithelial lining of odontogenic cysts.

    Full Text Available ABSTRACT: Herbicides used in the Clearfield® rice (Oryza sativa L. production system have a potential for leaching. This can result in contamination of underground water resources and cause injury to not tolerant crops that are sown in a succession and/or crop rotation. The objective of this study was to determine the leaching potential and the residual activity of the herbicides used in the Clearfield® rice system. The experiment was conducted over a period of two years and consisted of conducting a field test to be followed by two bioassays with a year of difference between their implementation. Initially an experiment was conducted in lowland area where it was planted the cultivar of rice ‘PUITA INTA CL’. Approximately one and two years thereafter, soil samples from each plot were collected at intervals of 5cm to a depth of 30cm (B factor for the bioassay to evaluate persistence of herbicides. Factor A was composed of mixtures formulated of imazethapyr + imazapic (75 + 25g a.i. L-1, imazapyr + imazapic (525 + 175g a.i. kg-1 in two doses, imazethapyr (100g a.i. L-1 and treatment control without application. Basing on results, it was concluded that the mixtures imazethapyr + imazapic, imazapyr + imazapic and imazethapyr leached into the soil, reaching depths of up to 25cm in lowland soil. Imidazolinone herbicides used today in the irrigated rice Clearfield® system are persistent in soil, and their phytotoxic activity can be observed up to two years after application.

    The importance of peroxy radicals in the tropospheric chemistry is well recognized in the scientific literature. Hydroxy- and organic peroxy radicals (HO2 and RO2, R being an organic chain) are key intermediates in the OH radical initiated oxidation of CO and SO2, of volatile organic compounds (VOC), in the ozonolysis of alkenes and photo-oxidation of carbonyl species. Peroxy radicals are responsible for the ozone production in the troposphere, the formation of peroxides and other oxidants. Although radical chemistry in the troposphere has been subject of intensive research in the past three decades, it is still very few known about the vertical distribution of peroxy radicals. Airborne observations are scarce in spite of their particular importance to improve the understanding of the tropospheric chemistry and the oxidising capacity of the atmosphere at different altitudes. In situ trace gas measurements were carried out in summer 2010 on board of the INTA (Instituto Nacional de Técnicas Aeroespaciales) C212 aircraft over Spain in the frame of the EUFAR project VERDRILLT (VERtical Distribution of Radicals In the Lower Layers of the Troposphere), and in cooperation with the DLR (Deutsches Zentrum für Luft- und Raumfahrt), the University of Wuppertal, the CEAM (Centro de Estudios Ambientales del Mediterráneo) and the UPV-EHU University in Bilbao. VERDRILLT aimed at getting a deeper understanding of the vertical distribution of peroxy radicals in the lower layers of the troposphere. Measurements were taken over urban areas and extensions of different vegetation under meteorological conditions favouring active photochemistry and convection from the ground into close atmospheric layers. Results and main findings will be presented and discussed.

    The objective of this study was to investigate the antimicrobial resistance, Tn1546 transposon variability and plasmid diversity among Polish vancomycin-resistant Enterococcus faecium (VREfm) isolates of VanA phenotype in the context of their clonal structure. Two hundred sixteen clinical VREfm isolates collected between 1997 and 2010 were studied by antimicrobial susceptibility testing, MLST, MLVA and detection of IS16, esp Efm, pilA, intA and plasmid-specific genes by PCR. Tn1546 structure was revealed by overlapping PCR and sequencing. Selected isolates were subjected to PFGE-S1 and Southern hybridization analyses. The vast majority of the isolates (95.8 %) belonged to lineages 17/18 (during the whole study period 1997-2010) and 78 (mostly in 2006-2010) of hospital-adapted meroclone of E. faecium. All isolates displayed a multi-drug resistance phenotype. Twenty-eight Tn1546 types (including 26 novel ones) were associated with eight different ISs (IS1216, IS1251, ISEfa4, ISEfa5, ISEfm2, ISEf1, IS3-like, ISEfm1-like). The vanA-determinant was typically located on plasmids, which most commonly carried rep2pRE25, rep17pRUM, rep18pEF418, rep1pIP501, ω-ε-ζ and axe-txe genes. VanA isolates from 1997-2005 to 2006-2010 differed in clonal composition, prevalence of gentamicin- and tetracycline-resistance and plasmidome. Our analysis revealed high complexity of Tn1546-type transposons and vanA-plasmids, and suggested that diverse genetic events, such as conjugation transfer, recombination, chromosomal integration and DNA mutations shaped the structure of these elements among Polish VREfm.

    NASA hosts three complexes worldwide built for spacecraft tracking, whose sensitive antennas are suitable for radio astronomy. Since more than a decade, INTA has managed guaranteed Spanish time at the complex located in Robledo de Chavela, in the frame of the Host Country Radio Astronomy (HCRA) program. Until now, the vast majority of the scientific results were achieved using a K-band (18 to 26 GHz) receiver, attached to the 70m antenna, and a narrow-band autocorrelator. In the recent years, we have undertaken two large instrumental projects: (1) the incorporation of a second antenna (34m in diameter), working in Q-band (38 to 50 GHz); and (2) the design and construction of a wideband backend, which may operate with both the Q- and K-band receivers, providing instantaneous bandwidths from 100 MHz to 6 GHz, and resolutions from 6 to 200 kHz. The new wideband backend is expanding the HCRA possibilities due its bandwidth, versatility, spectral resolution and stability of the baselines. Its IF processor splits each of the two circular-polarization signals, and downconverts them to four base-band channels, 1.5 GHz width. Two different frequencies may be tuned independently. Digitalisation is done through FPGA-based FFT spectrometers, which may be independently configured. Once end-to-end assembled, the commissioning of the new backend was done using the 34m antenna in Q-band. We report the main characteristics of both the antenna recently incorporated to HCRA, and the wideband backend.

    Low molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their complex protein banding patterns in SDS-PAGE and tight linkage with gliadins at the Gli-1 locus. Using DNA markers and a backcross program we developed a set of nine near isogenic lines (NILs) including different Glu-A3/GliA-1 or Glu-B3/Gli-B1 alleles in the genetic background of the Argentine variety ProINTA Imperial. The nine NILs and the control were evaluated in three different field trials in Argentina. Significant genotype-by-environment interactions were detected for most quality parameters indicating that the effects of the Glu-3/Gli-1 alleles are modulated by environmental differences. None of the NILs showed differences in total flour protein content, but relative changes in the abundance of particular classes of proteins cannot be ruled out. On average, the Glu-A3f, Glu-B3b, Glu-B3g and Glu-B3iMan alleles were associated with the highest values in gluten strength-related parameters, while Glu-A3e, Glu-B3a and Glu-B3iChu were consistently associated with weak gluten and low quality values. The value of different Glu3/Gli-1 allele combinations to improve breadmaking quality is discussed. PMID:27818572

    Full Text Available Age related macular degeneration (AMD is a leadi ng cause of irreversible blindness among the elderly worldwide affecting 30 - 50 million individuals. AMD is more common in developed world. AMD is characterized by central visual loss. Advanced AMD can be classified in broadly into two types: dry and wet fo rm. Several clear risk factors for the development and progression of age related macular degeneration have been established are advancing age, genetic factors, history of smoking ,white race, obesity, high dietary intake of vegetable fat, low dietary inta ke of antioxidants and zinc. This prospective non - interventional study was conducted from February 2011 to October 2012 in the Regional Institute of Ophthalmology, Hamidia Hospital, Bhopal, included patients who attended the eye OPD, retina clinic and eye ward and were diagnosed as a case of AMD. Present study included 174 patients out of which patients 79(45.39% were above the age of 70 years, with 51 (29.31% patients between 61 - 70 years and 44 cases (25.28% in the sixth decade. Male: female ratio was 0 .75: 1. 21 (12.06% patients have a positive family history of AMD. Most common risk factor identified in our study was chronic sun exposure (49.42% followed by hypertension in 41.8% patients. 25.26% cases gave history of smoking and raised serum cholest erol levels were seen in 14.28% cases. History of alcoholism was positive in 19.54% patients. Of the 174 cases in our present study 90 patients (51.72% were hypermetropic. Conclusion: Age related macular degeneration is a disease of elderly with risk fact ors, most of them are preventable. If timely proper measures are taken, a major cause of blindness can be prevented in elderly age group.

    Full Text Available Amyloid deposits within the islet of the pancreas have been known for a century. In 1987, the islet amyloid precursor polypeptide (IAPP amylin (a 37 amino acid was discovered. Recently there has been an explosion of amylin's importance in the development of type 2 diabetes mellitus (T2DM. This review is intended to share what is understood about amylin derived amyloid and the role it plays in T2DM. Whether islet amyloid is an epiphenomenona, a tombstone, or a trigger it leaves an indelible footprint in greater that 70% of the patients with T2DM. There is current data supporting the damaging role of intermediate sized toxic amyloid particles to the beta cell resulting in a beta cell defect which contributes to a relative deficiency or loss of insulin secretion. Within the islet there is an intense redox stress which may be associated with the unfolding of amylin's native secondary structure compounding its amyloidogenic properties. In addition to the beta cell defect there may be an absorptive defect as a result of amyloid deposition in the basement membranes which form an envelope around the inta-islet capillary endothelium. We have an opportunity to change our current treatment modalities with newer medications and we should attempt to diagnose T2DM earlier and use these newer treatment strategies in combination to decrease glucotoxicity without elevating endogenous insulin and amylin. In the 21st century our goal should be to prevent remodeling, save the pancreatic islet, conquer islet amyloid, and amyloid diabetes.

    Since 1988 INTA (the National Institute for Aerospace Technology in Spain) has been running hydrogen and fuel cells activities supported by own funds. Up to 1996, subsidies from the regional government of Andalucia (south of Spain), were provided for building a solar hydrogen production pilot plant based on photovoltaic powered water electrolysis. At present there is not a specific programme devoted to hydrogen energy and fuel cells in Spain, however, the Spanish Plan for Scientific Research, Technological Development and Innovation (2004-2007) in the energy area, will consider these topics as separate items included in the priority devoted to renewable energies and emerging technologies. This means that part of the R and D budget will be allocated for hydrogen and fuel cells projects but competing with the rest of renewable energies projects. Nevertheless the possibilities to approve projects for national funding are considered in a very wide and detailed way in the rationale of the national R and D programme, as mentioned in the following paragraphs: Hydrogen, by means of fuel cells technological evolution, presents a potential to become in the long term an energy carrier that changes the energetic sector configuration, making it safer, more efficient and more respectful with environment. For achieving this goal, a number of technological barriers must be overcome within production, storage, distribution and final supply, both for its utilization in transport and stationary applications. Fuel Cells are gaining in Spain increasing importance both for stationary and transport utilization, as a consequence of its different types, modular characteristics and the possibility for utilization in different applications, as domestic use, distributed and centralized generation. Due to its wide variety of possibilities and its characteristics of low environmental impact and reduced noise production, fuel cells become themselves a energetic objective. (O.M.)

    Dfgfdg Due to international environmental regulations, aircraft turbojet manufacturers are required to analyze the gases exhausted during engine operation (CO, CO2, NOx, particles, unburned hydrocarbons (aka UHC), among others).Standard procedures, which involve sampling the gases from the exhaust plume and the analysis of the emissions, are usually complex and expensive, making a real need for techniques that allow a more frequent and reliable emissions measurements, and a desire to move from the traditional gas sampling-based methods to real time and non-intrusive gas exhaust analysis, usually spectroscopic. It is expected that the development of more precise and faster optical methods will provide better solutions in terms of performance/cost ratio. In this work the analysis of high-speed infrared emission spectroscopy measurements of plume exhaust are presented. The data was collected during the test trials of commercial engines carried out at Turbojet Testing Center-INTA. The results demonstrate the reliability of the technique for studying and monitoring the dynamics of the exhausted CO2 by the observation of the infrared emission of hot gases. A compact (no moving parts), high-speed, uncooled MWIR spectrometer was used for the data collection. This device is capable to register more than 5000 spectra per second in the infrared band ranging between 3.0 and 4.6 microns. Each spectrum is comprised by 128 spectral subbands with aband width of 60 nm. The spectrometer operated in a passive stand-off mode and the results from the measurements provided information of both the dynamics and the concentration of the CO2 during engine operation.

    Full Text Available At present, the topic of automated vehicles is one of the most promising research areas in the field of Intelligent Transportation Systems (ITS. The use of automated vehicles for public transportation also contributes to reductions in congestion levels and to improvements in traffic flow. Moreover, electrical public autonomous vehicles are environmentally friendly, provide better air quality and contribute to energy conservation. The driverless public transportation systems, which are at present operating in some airports and train stations, are restricted to dedicated roads and exhibit serious trouble dynamically avoiding obstacles in the trajectory. In this paper, an electric autonomous mini-bus is presented. All datasets used in this article were collected during the experiments carried out in the demonstration event of the 2012 IEEE Intelligent Vehicles Symposium that took place in Alcalá de Henares (Spain. The demonstration consisted of a route 725 metres long containing a list of latitude-longitude points (waypoints. The mini-bus was capable of driving autonomously from one waypoint to another using a GPS sensor. Furthermore, the vehicle is provided with a multi-beam Laser Imaging Detection and Ranging (LIDAR sensor for surrounding reconstruction and obstacle detection. When an obstacle is detected in the planned path, the planned route is modified in order to avoid the obstacle and continue its way to the end of the mission. On the demonstration day, a total of 196 attendees had the opportunity to get a ride on the vehicles. A total of 28 laps were successfully completed in full autonomous mode in a private circuit located in the National Institute for Aerospace Research (INTA, Spain. In other words, the system completed 20.3 km of driverless navigation and obstacle avoidance.

    A new kind of planetary exploration mission for Mars is under development in collaboration between the Finnish Meteorological Institute (FMI), Lavochkin Association (LA), Space Research Institute (IKI) and Institutio Nacional de Tecnica Aerospacial (INTA). The Mars MetNet mission is based on a new semi-hard landing vehicle called MetNet Lander (MNL).The scientific payload of the Mars MetNet Precursor mission is divided into three categories: Atmospheric instruments, Optical devices and Composition and structure devices. Each of the payload instruments will provide significant insights in to the Martian atmospheric behavior.The key technologies of the MetNet Lander have been qualified and the electrical qualification model (EQM) of the payload bay has been built and successfully tested.Full Qualification Model (QM) of the MetNet landing unit with the Precursor Mission payload is currently under functional tests. In the near future the QM unit will be exposed to environmental tests with qualification levels including vibrations, thermal balance, thermal cycling and mechanical impact shock. One complete flight unit of the entry, descent and landing systems (EDLS) has been manufactured and tested with acceptance levels. Another flight-like EDLS has been exposed to most of the qualification tests, and hence it may be used for flight after refurbishments. Accordingly two flight-capable EDLS systems exist. The eventual goal is to create a network of atmospheric observational posts around the Martian surface. The next step in the MetNet Precursor Mission is the demonstration of the technical robustness and scientific capabilities of the MetNet type of landing vehicle. Definition of the Precursor Mission and discussions on launch opportunities are currently under way. The baseline program development funding exists for the next five years. Flight unit manufacture of the payload bay takes about 18 months, and it will be commenced after the Precursor Mission has been defined.

    Highlights: • The status of Equatorial Visible/Infra-Red Wide Angle Viewing System is presented. • An assessment of measurement parameters relevant for machine protection has been done. • Remaining uncertainties will be clarified during the System Level Design (SLD). • WAVS design is not considered mature enough to launch prototypes of subcomponents. • Mandatory prototypes and qualification tests are already identified. • Next stage (SLD) will enable to do trade-offs and address pending design issues. - Abstract: The Equatorial Visible/Infra-Red Wide Angle Viewing System (WAVS) is one of the ITER key diagnostics owing to its role in machine investment protection through the monitoring of Plasma Facing Components (PFCs) by Infra-Red thermography and visible imaging. Foreseen to be installed in 4 equatorial port plugs to maximize the coverage of divertor, first wall, heating antennas and upper strike zone, the WAVS will likely be composed of 15 lines of sight and 15 optical systems transferring the light along several meters from the PFCs through the port plug and interspace up to detectors located in the port cell. After a conceptual design phase led by ITER Organization, the design is being further developed through a Framework Partnership Agreement signed between the European Domestic Agency, Fusion for Energy, and a consortium gathering CEA, CIEMAT (with INTA as third party) and Bertin Technologies company. The next design step is the System Level Design (SLD) which will enable to consolidate the WAVS specifications as well as the performance realistically achievable (taking into account ITER and project constraints). The SLD has been preceded by a preparatory phase aiming at clarifying the WAVS functions and identifying critical prototyping. The outcomes of this preparatory phase are reported in this paper. First a review by the consortium of the WAVS measurement specifications is presented, for the purpose of a clearer separation of measurement

    Full Text Available Las gliadinas son proteínas del trigo que desempeñan un papel central en la formación del gluten, ya que son las responsables de la viscosidad de la red. Pese a su importancia han sido menos estudiadas que las gluteninas, debido a que sus inusuales propiedades de solubilidad e hidrofobicidad dificultan su caracterización. Los objetivos de este trabajo fueron estudiar el perfil proteico de las gliadinas de cultivares de trigos argentinos mediante electroforesis capilar, y evaluar la capacidad de esta técnica para discriminar entre los diferentes cultivares. Para ello se trabajó con 12 cultivares de trigo de las diferentes categorías de calidad asignadas por el INTA, a los que se caracterizó en cuanto a su composición y calidad tecnológica y se les extrajo las gliadinas para estudiarlas por electroforesis capilar. Los resultados obtenidos confirman el potencial de esta técnica para lograr separaciones de gliadinas, con la ventaja de requerir poca preparación y poca cantidad de la muestra analizada y sencillos protocolos de limpieza y mantenimiento de capilar, permitiendo el análisis de gran cantidad de muestras. Asimismo, se demostró la capacidad de la electroforesis capilar para discriminar diferentes cultivares sobre la base de su perfil de gliadinas, lo que permite la diferenciación de genotipos.Gliadins are a group of wheat proteins that play a major role in gluten development since they account for net viscosity. Despite this fact, gliadins have not been studied as deeply as glutenins because of their unusual solubility properties and their high hydrophobicity. The objectives of this work were to study the gliadin profile of Argentinean wheats comprising a broad quality range by means of capillary electrophoresis and to assess the suitability of this technique for wheat cultivar discrimination. For this purpose, chemical compositions of twelve wheat cultivars belonging to different quality groups were determined. Besides, flour

    Chile has suffered a fast increase in childhood obesity in the last 10 years. As a result, several school programmes have been implemented, however the effectiveness of these needs to be evaluated to identify and prioritize strategies to curve this trend. Cluster randomized controlled trial. Twelve primary public schools chosen at random over three regions of the country will take part in this study. The sample size consisted of a total of 1,655 children. For each region one school will be selected for each of the three nutritional intervention modes and one school will be selected as the control group. The intervention modes consist of the following: Healthy Kiosk and nutritional education (KSEAN); Optimized physical activity (AFSO); Healthy Kiosk and nutritional education (KSEAN) + optimized physical activity (AFSO); Control group. The effectiveness of each intervention will be evaluated by determining the nutritional condition of each child by measuring percentage of body fat, BMI and the z-score of the BMI. This study will also identify the eating behaviours, nutritional knowledge and fitness of each child, along with the effective time of moderate activity during physical education classes. A protocol to evaluate the effectiveness of a school based intervention to control and/or reduce the rates of childhood obesity for children between 6 and 10 years of age was developed. The protocol was developed in line with the Declaration of Helsinski, the Nüremberg Code and the University of Chile Guidelines for ethical committees, and was approved by the INTA, Universidad de Chile ethical committee on Wednesday 12 March 2014. There is consensus among researchers and health and education personnel that schools are a favourable environment for actions to prevent and/or control childhood obesity. However a lack of evidence on the effectiveness of interventions to date has led some to question the wisdom of allocating resources to programmes. This is the first study

    NASA has three satellite tracking stations around the world: CDSCC (Canberra, Australia), GDSCC (Goldstone, USA) and MDSCC (Madrid, Spain). One of the antennas located at MDSCC, DSS-61, is not used for satellite tracking any more and thanks to an agreement between INTA (Instituto Nacional de TA~l'cnica Aeroespacial) and NASA, it has been turned into an educational radio telescope. PARTNeR (Proyecto Académico con el RadioTelescopio de NASA en Robledo, Academic Project with the NASA Radio Telescope at Robledo) is a High School and University radio astronomy educational program that allows teachers and students to control this 34-meter radio telescope and conduct radio astronomical observations via the Internet. As radio astronomy is not a popular subject and astronomy has little presence in the High School Curriculum, teachers need specific training in those subjects to implement PARTNeR. Thus, High School teachers joining the project take a course to learn about the science of radio astronomy and how to use the antenna in their classrooms. Also, teachers are provided with some learning activities they can do with their students. These lesson plans are focused on the implementation of the project within an interdisciplinary framework. All educational resources are available on PARTNeR website. PARTNeR is an inquiry based approach to science education. Nowadays, students can join in three different observational programmes: variability studies in quasars, studies of radio-bursts in X-ray binaries (microquasars), and mapping of radio sources in the galactic plane. Nevertheless, any other project can be held after an evaluation by the scientific committee. The operational phase of the project started in the academic year 2003-04. Since then, 85 High Schools, seven Universities and six societies of amateur astronomers have been involved in the project. During the 2004-09 period, 103 High School teachers from Spain and Portugal have attended the training courses, and 105

    We are developing a new kind of planetary exploration mission for Mars - MetNet in situ observation network based on a new semi-hard landing vehicle called the Met-Net Lander (MNL). The eventual scope of the MetNet Mission is to deploy some 20 MNLs on the Martian surface using inflatable descent system structures, which will be supported by observations from the orbit around Mars. Currently we are working on the MetNet Mars Precursor Mission (MMPM) to deploy one MetNet Lander to Mars in the 2009/2011 launch window as a technology and science demonstration mission. The MNL will have a versatile science payload focused on the atmospheric science of Mars. Detailed characterization of the Martian atmospheric circulation patterns, boundary layer phenomena, and climatology cycles, require simultaneous in-situ measurements by a network of observation posts on the Martian surface. The scientific payload of the MetNet Mission encompasses separate instrument packages for the atmospheric entry and descent phase and for the surface operation phase. The MetNet mission concept and key probe technologies have been developed and the critical subsystems have been qualified to meet the Martian environmental and functional conditions. Prototyping of the payload instrumentation with final dimensions was carried out in 2003-2006.This huge development effort has been fulfilled in collaboration between the Finnish Meteorological Institute (FMI), the Russian Lavoschkin Association (LA) and the Russian Space Research Institute (IKI) since August 2001. Currently the INTA (Instituto Nacional de Técnica Aeroespacial) from Spain is also participating in the MetNet payload development. To understand the behavior and dynamics of the Martian atmosphere, a wealth of simultaneous in situ observations are needed on varying types of Martian orography, terrain and altitude spanning all latitudes and longitudes. This will be performed by the Mars MetNet Mission. In addition to the science aspects the

    In the course of a geochronological study of the volcanic activity in the Andean Cordillera in northern Argentina, we have found in the El Quevar volcanic complex (24 deg. 19{sup '}S/66 deg. 43{sup '}W,6180m) a phenocryst poor obsidian (Quiron obsidian) showing an unusually high spontaneous track density. Defects which might produce 'spurious' tracks are virtually absent. Application of fission-track dating using an absolute approach, based on the IRMM-540 standard glass for neutron fluence measurements, yielded an apparent age of 7.27+/-0.29Ma(1{sigma}) and a plateau age of 8.99+/-0.31Ma(1{sigma}). A {sup 40}Ar-{sup 39}Ar isochron age on biotite of 8.61+/-0.04Ma(1{sigma}) was already available for the Quiron rhyolite. We determined further {sup 40}Ar-{sup 39}Ar ages on several chips of the glass itself using two analytical approaches: total fusion with a focussed laser beam (LTFA) and a step-heating approach using a de-focussed laser beam (LSHA). We have obtained a weighted average of 8.77+/-0.09Ma, an isochron age of 8.71+/-0.12Ma and an integrated age of 8.77+/-0.09Ma for LTF analyses, and a w.a. of 8.75+/-0.09Ma, an iso.a. of 8.77+/-0.09Ma and an int.a. of 8.77+/-0.09Ma for LSH analyses (all age errors are 2{sigma}). The Quiron obsidian is very easy to analyse for its high spontaneous track density and because microlites which might produce spurious tracks are very rare. Independent reference {sup 40}Ar-{sup 39}Ar ages determined in different laboratories are available. For these reasons we believe that this glass may be very useful for testing fission-track system calibrations and apparent age correction procedures. Splits of obsidian Quiron will be distributed upon request to colleagues who intend to test it.

When our laboratory observations are compared with some existing observations of purported EEP data, (ibid.

    Mobile small-aperture array RUKSA in Hautavaara - Petrozavodsk region of Rus- sian Karelia - operated as part of SVEKALAPKO (EUROPROBE) experiment in September- October 1999. The region is characterised by complicated tectonic setting and modern tectonic activity. It is the junction zone between exposed Archaean, Sve- cofennian and Phanerozoic crustal segments. The array consisted of six vertical and three 3-component loggers with analogue preliminary amplifiers connected by cable lines to digital recording system. Loggers were positioned on symmetric concentric rings with the outer ring diameter 640 m and the inner ring diameter 300 m. Dy- namic range of the analogue recorders SM-3KV is 120 dB. The sampling rate is 100 Hz. About 100 seismic events of different origin were recorded during experiment, including the largest earthquakes of 1999 in Turkey, Taiwan, and Greece. The qual- ity of records is extremely high. The array data were used for analysis of coherency, scattering and polarization properties of signal and microseism noise. The RUKSA records demonstrate remarkable coherency of teleseismic signal within the frequency band of 0.2-5 Hz. The level of microseism noise is very low compared to other small- aperture array sites. Polarisation analysis of the first P pulses for teleseismic waves re- vealed regular azimuth dependence of P wave azimuth and incidence angle deviations. Three-component records of teleseismic signals were processed with "receiver func- tion" method (Kind et. al, 1995). Previously this approach was used in regional-scale studies for broad-band record analysis. This study presents the first positive result of application of the method to short-period array data. Position of the main boundaries in the upper lithosphere under the array, inferred from "receiver function" analysis, coincides well with results of complex geological and geophysical study including re- flection surveys.

    Ozone and carbon monoxide have been investigated in the GAW-WMO station of Ushuaia (Argentina), using hourly values during five years (2010-2014). This work has been developed in the framework of HELADO (Halogens in the Antarctic atmosphere and its role in the Ozone distribution) project and under the collaboration between INTA (National Institute for Aerospace Technology - Spain), SMN (National Meteorological Service - Argentina) and AEMET (State Meteorological Agency - Spain). Meteorological features have been analyzed with in-situ observations and meteorological fields from ECMWF 0.5° as spatial resolution model. These fields have been applied to compute back trajectories with HYSPLIT model. Independently of season, mostly atmospheric flows coming from W-SW (South Pacific Ocean), theses westerlies winds are associated with low pressure systems; in addition with lower frequencies are collected winds from South (Antarctic Peninsula and Weddell Sea), polar easterlies. Hourly averages of surface (in-situ) ozone and CO levels were 20±7 and 71±45 ppb respectively, typical values of remote environments. A clear seasonal pattern has been obtained for surface ozone with monthly peaks in winter of 25 ppb and minimum in summer with 12 ppb; a similar behaviour is found for CO, 93 and 48 ppb for maximum and minimum values, respectively. A weak daily cycle has been obtained in both species, amplitude for ozone of 2-4 ppb and 13-20 ppb for CO. The seasonal levels behaviour for surface ozone is also observed in upper levels, approximately from surface up to 5 km. This result has been obtained from 139 ozone profiles launched in the studied period. Since the ozone precursors and carbon monoxide emissions are low in this area, the origin of the values observed could be in the atmospheric transport processes. As hypothesis to explain the behaviour observed, we suggest that in the warm season with solar radiation, the photochemical mechanisms are active, and the elimination

    现实主义的回归是近几年来少数民族文学创作的突出特征,通过对当下少数民族小说、诗歌、散文的扫描,我们发现回归的现实主义既包含19世纪经典现实主义手法,也有着自然主义书写,更有吸收了先锋文学营养的日常写作,更涵盖了以“真实性”为旨归的非虚构写作,这种现实主义是因应现实而不断以不同面貌呈现的“流动的现实主义”。尽管在当下少数民族文学中,现实主义及其不同变体取得了一定的实绩,但存在着平面化、狭隘化和窄化的风险,需要结合卢卡契的总体性与布莱希特的现实感,倡导一种全面、立体、完整地呈现、再现与表现的创作自觉。%The return of realism is an outstanding feature of minority literary creation in recent years. Through a scan of contemporary minority novels,poems and essays,we find that the return of realism includes the classical realist techniques of the 19th century,an a-doption of naturalism,an intaKe of vanguard literature’s nutrition,and the non-fic-tional writing based on“reality”. Hence,the realism is a“flowing realism”that taKes on a different looK in a different situation. It is argued that much progress has been made in terms of varieties of realism in contemporary minority literature,yet there are risKs of flatness,insularity and narrowness;hence,the overall features of Georg Luacs and the realistic features of Bertolt Brecht should be combined so as to advocate an o-verall,cubic and entire creation self-awareness of presentation,re-presentation and expression.

Docetaxel (DTX, under the trade name Taxotere™, is one of the representative anticancer chemotherapeutic agents of this era. However, this highly lipophilic and insoluble drug has many adverse effects. Our novel and widely applicable nanoparticulation using fat and supercritical fluid (NUFS™ technology enabled successful nanoscale particulation of DTX (Nufs-DTX. Nufs-DTX showed enhanced dissolution rate and increased aqueous stability in water. After confirming the preserved mechanism of action of DTX, which targets microtubules, we showed that Nufs-DTX exhibited similar effects in proliferation and clonogenic assays using A549 cells. Interestingly, we observed that Nufs-DTX had a greater in vivo tumor growth delay effect on an A549 xenograft model than Taxotere™, which was in agreement with the improved drug accumulation in tumors according to the biodistribution result, and was caused by the enhanced permeability and retention (EPR effect. Although both Nufs-DTX and Taxotere™ showed negative results for our administration dose in the hematologic toxicity test, Nufs-DTX showed much less toxicity than Taxotere™ in

    de La Torre Noetzel, Rosa

    The Lithopanspermia hypothesis assumes that impact-expelled rocks serve as interplanetary transfer vehicles for microorganisms colonizing those rocks. It requires that the microorganisms survive (1) the impact ejection process from the planet of origin; (2) travelling through space; (3) capture and landing on another planet. In the experiment "Lithopanspermia" on board of the FOTON-M3 satellite (14.09.07) steps 2 and 3 of this scenario have been experimentally tested. Assay systems for step 2 were the bipolar epilithic lichen species Rhizocarpon geographicum and Xanthoria elegans on their natural rock substrate as well as their reproduction structures, microbial communities from atacamás halites Chroococcidiopsiss, endolithic communities of Anabaena and Nostoc, and the vagrant lichen species Aspicilia fruticulosa. The samples were exposed to outer space conditions within the BIOPAN-6 facility of ESA. Preparatory space simulation studies (UV solar spectrum radiation and vacuum at 10-2 Pa) performed at the Spasolab-Laboratory of INTA (March-April 2007), have demonstrated the suitability of those lichen species. After flight (10 days exposure to harsh space conditions in low Earth orbit at about 300 km altitude) and recovery, the survival capacity of the microbial communities has been assayed. First analyses have confirmed a fast recovery of the biological activity (chlorophyll a- fluorescence) of the lichens, similar to the high survival rates observed in the experiment LICHENS onboard of the Foton-M2 mission (de la Torre et al., 2007; Sancho et al., 2007). There were no significant changes in relation with the pre-flight values of the epilithic-, endolithicand vagrant lichen samples. First results of Confocal Scanning Laser Microscopy have demonstrated a high vitality of epilithic samples. Ultrastructural changes are being analyzed by Transmission Electron Microscopy and Cryoscanning. Furthermore, concerning the germination capacity of ascospores of Xanthoria

    Please fill in your abstract text. Mars Global Surveyor (MGS) mission has played a unique role in the mapping of the Martian magnetic field. Thanks to the results and later data analysis of this mission it is known that Mars does not have a global bipolar magnetic field but that the crust presents areas of great magnetization. This fact is only compatible with a large concentration of highly magnetic minerals (magnetite) with a pinned monodomain magnetization [1, 2]. The next MetNet precursor mission (MMPM) aims to place a net of meteorological stations on the surface of Mars. In the first of them (est. 2014), among other payloads, the Spanish Institute of Aerospace Technology (INTA) has developed a miniaturized vector magnetometer with the goal of measuring the thermomagnetic response of the Martian soil around the lander. The work presented here discusses possible microstructures for the magnetic minerals in the Martian crust. The results presented will be focused on the titanomagnetites series [3] solid solution with compositions of: x (Fe2TiO4) - (1-x) (Fe3O4) with 0.30 Wasilewski, and P.

    A new kind of planetary exploration mission for Mars is being developed in collaboration between the Finnish Meteorological Institute (FMI), Lavochkin Association (LA), Space Research Institute (IKI) and Institutio Nacional de Tecnica Aerospacial (INTA). The Mars MetNet mission is based on a new semi-hard landing vehicle called MetNet Lander (MNL). The main idea behind the MetNet landing vehicles is to use a state-of-the-art inflatable entry and descent system instead of rigid heat shields and parachutes as earlier semi-hard landing devices have used. This way the ratio of the payload mass to the overall mass is optimized and more mass and volume resources are spared for the science payload. The vehicle decelerates its entry speed using the inflatable structure and final landing sequence includes a cone headed body penetrating the Martian soil. It is planned to deploy several tens of MNLs on the Martian surface operating at least partly at the same time to allow meteorological network science. The payload of the two MNL precursor models includes the following instruments: Atmospheric instruments: - Pressure device (MetBaro): mass 100g, measurement range 0..1015 hPa. - Humidity device (MetHumi): mass 15g, measurement range 0..100%RH. - Temperature sensors (MetTemp): mass 2g each, measurement range -110C..+30C. Optical devices: - Panoramic camera (PanCam): mass 100g, FOV 4 lenses mounted at 90 deg - Solar irradiance sensor (MetSIS) with optical wireless system (OWLS) for data transfer: mass 115g (MetSIS) and 7g (OWLS module), wavelength range 190..1100nm. MetSIS equipped with 28 optical detectors, two temperature sensors and two solar incidence angle detectors. - Dust sensor (DS): mass 42g, resolution: 10 particles / cm3. Composition and structure device: - Magnetometer (MOURA): mass 80g, measurement range: ±30uT. MetNet Mission payload instruments are specially designed to operate in very low power conditions.

    Immunosensors have been extensively used since many years for environmental monitoring. Different technological platforms allow new biosensor designs and implementations. We have reported (Rivas et al., 2008) a shotgun approach for antibody production for biomarker detection in astrobiology and environmental monitoring, the production of 150 new polyclonal antibodies against microbial strains and environmental extracts, and the construction and validation of an antibody microarray (LDCHIP200, for "Life Detector Chip") containing 200 different antibodies. We have successfully used the LDCHIP200 for the detection of biological polymers in extreme environments in different parts of the world (e.g., a deep South African mine, Antarctica's Dry valleys, Yellowstone, Iceland, and Rio Tinto). Clustering analysis associated similar immunopatterns to samples from apparently very different environments, indicating that they indeed share similar universal biomarkers. A redundancy in the number of antibodies against different target biomarkers apart of revealing the presence of certain biomolecules, it renders a sample-specific immuno-profile, an "immnuno-fingerprint", which may constitute by itself an indirect biosignature. We will present a case study of immunoprofiling different iron-sulfur as well as phylosilicates rich samples along the Rio Tinto river banks. Based on protein microarray technology, we designed and built the concept instrument called SOLID (for "Signs Of LIfe Detector"; Parro et al., 2005; 2008a, b; http://cab.inta.es/solid) for automatic in situ analysis of soil samples and molecular biomarkers detection. A field prototype, SOLID2, was successfully tested for the analysis of grinded core samples during the 2005 "MARTE" campaign of a Mars drilling simulation experiment by a sandwich microarray immunoassay (Parro et al., 2008b). We will show the new version of the instrument (SOLID3) which is able to perform both sandwich and competitive immunoassays. SOLID3

    Lichens, endolithic- and endoevaporitic communities of cyanobacteria and bacteria has been exposed to real- and simulated space conditions to demonstrate likelihood of the lithopanspermia hypothesis, that postulates a viable transport of microorganisms between planets by means of meteorites, i.e. impact expelled rocks from a planets surface, which serve as vehicles for spreading living material from one planet or solar system to another (Nicholson et al. 2000, Benardini et al. 2003, Cockell 2008, Horneck et al. 2008, Valtonen et al. 2009). Three experiments (LICHENS, Foton M2 mission, 2005, and LITHOPANSPERMIA, Foton-M3 satellite, 2007), have been performed in space, the first two on a short mission, onboard of Biopan of the Foton-M satellite recoverable capsule, and the third one in a long-term mission on the Expose facility of the ISS to test the survival of prokaryotic- and eukaryotic symbiotic organisms in relation to lithopanspermia. The first two experiments allowed for the first time the demonstration- and intercomparison of the high survival capacity of eukaryotic- and prokaryotic symbiotic organisms in space (the epilithic lichen species Rhizocarpon geographicum and Xanthoria elegans, endoevaporitic microbial communities, epilithic microbial communities with cyanobacterial akinetes of Anabaena, and a vagrant lichen species, Aspicilia fruticulosa). Exposure to different UV-conditions of a low Earth orbit (LEO, 300 km) were performed: solar extraterrestrial UV radiation, Mars simulated UV-climate, UV-B radiation and PAR, space vacuum at 10-6 mbar, microgravity and temperatures between -23°C and +16°C. To check the resistance of the selected organisms to space before these missions, space simulation experiments were performed at INTA (Spasolab) and DLR (Institute of Aerospace Medicine), which were decisive to show the high survival capacity of these species to space vacuum (10-4 - 10-6 mbar), space UV radiation (200-400 nm) and extreme temperatures.

  20. Allies in Biofuels. Opportunities in the Dutch - Argentinean biofuels trade relation

    Energy Technology Data Exchange (ETDEWEB)

    Verhagen, M.

    focuses on first generation biofuels and has only little experience with rapeseed, and second generation fuels. It is in both these areas that Dutch and European experience can play a role to develop Argentina's biofuels sector. Argentina, on the other hand can produce the amounts of biofuels that Europe and the Netherlands are demanding for in the short run. The outcome of research shows several recommendations to change biofuels policies for both countries. Furthermore, areas for cooperation were defined. In short: Dutch biofuels policy regarding international research and cooperation projects is too narrow. Argentina is an excellent partner but until now completely unnoticed. Teaming up with Brazil and making use of the same financial structures would be a possibility for the incorporation of Argentina in Dutch foreign biofuels activities; The Dutch initiative on criteria for sustainable production of biofuels appears overachieving, and hardly workable for producing countries. The dialogue with those countries - such as Argentina - should be intensified, in order to develop at least voluntary agreements, and to guarantee that both producer and consumer country are on the same team. The process is a two-way street; Argentina needs to stabilize policy development in order to bring stability to the biofuels sector and promote investments. Also, Argentina needs to develop a long-term strategy on biofuels and more actively pursue its national interests in the international arena specifically in terms of trade issues (WTO, normalization); Argentina's policy needs diversification. Brainstorming with experienced Dutch and European counterparts can distill instruments that are suitable for Argentina. Combined projects between Dutch and Argentinean institutes (SenterNovem, ECN, WUR, INTA) would be profitable in this area, as well as on more practical research regarding crop's life cycles, energy balances, technologies, etc. Modifications to policy and cooperation

This study was conducted during two consecutive vintages to assess its influence on the general composition, sensory attributes and preference of Vitis vinifera L. cv Malbec wines. Batches of 120 kg of grapes harvested from vines with different degrees of (visual symptoms of the disease were separately vinified. Grapes were grouped in three treatments: T1, grapes from vines with no symptoms; T2, grapes from vines with 10%–50% symptoms; and T3, grapes from vines with 50%–100% symptoms. Basic analyses of the grapes prior to crushing, and basic wine analysis were undertaken, together with spectrophotometric analyses of the wines after three months of bottle aging. The kinetics of alcoholic fermentation (AF was followed daily and additionally the wines were assessed by a sensory panel. T3 grapes were characterized by comparatively lower initial sugar contents and higher titratable acidity. The AF kinetics were unaffected in the wines arising from the diseased grapes. There was no clear-cut effect of the disease on the wines’ pH, volatile acidity, and total acidity; however, the later spectrophotometric analyses showed that the total phenolic index was the highest in T2 wines for both vintages. In 2005, the color index (CI was higher in T3 and showed the lowest value in 2006. The sensory properties of the wines were different in the two vintages. In 2005, T2 and T3 wines were perceived as having higher color intensity, violet hue and spicy notes, T2 being the most preferred wine. In 2006, T1 and T2 showed a much better sensory

    Full Text Available The present study involves preparation and evaluation of floating microspheres using famotidine (FM as a model drug for prolongation of the gastric retention time. The microspheres were prepared by the solvent evaporation method using different polymers, i.e. acrycoat S100 and cellulose acetate. The size or average diameter (d avg and surface morphology of the prepared microspheres were recognized and characterized by the optical and scanning electron microscopic methods, respectively. In vitro drug release studies were performed and the drug release kinetics were evaluated using the linear regression method. Effects of the stirring rate during preparation, polymer concentration on the size of the microspheres and drug release were also observed. The prepared microspheres exhibited prolonged drug release (18 h and remained buoyant for more than 12 h. The mean particle size increased and the drug release rate decreased at a higher polymer concentration. No significant effect of the stirring rate during preparation on drug release was observed. In vitro studies demonstrated a diffusion-controlled drug release from the microspheres. The objective of the present study was to develop floating microspheres of FM in order to achieve an extended retention in the upper gastrointestinal tract, which may result in enhanced absorption and thereby improved bioavailability. The prepared microspheres were evaluated for particle size, in vitro release and buoyancy and incorporation efficiency. The effect of various formulation variables on the size and drug release was investigated. In vitro drug release studies were performed and the drug release kinetics were evaluated using the linear regression method. FM was obtained as a gift sample from Intas Pharmaceuticals, Ahmedabad, India. Polyvinyl alcohol was obtained from S.D. Fine Chemicals Ltd., Mumbai, India. Dichloromethane, acrycoat S100, cellulose acetate and Tween 80 were obtained from Central Drug House (P

    El Crespo stream is located inside a small watershed (52,000 Ha) which is only influenced by farming activities without urban or industrial impact. The watershed can be divided in two areas, the southern area (upstream), mainly composed of intensive crops and the northern area (downstream) used only for extensive livestock. In this sense, "El Crespo" stream in an optimal site for monitoring screening of pesticide residues. The objective of this work was to determine the seasonal and spatial variations of glyphosate (GLY), in surface waters of "El Crespo" stream. We hypothesized that in surface waters of "El Crespo" stream the levels of GLY vary depending of the season and rainfall events. The water sampling was carried out from October to June (2014-2015) in two sites: upstream (US) and downstream (DS), before and after rain events. The water samples were collected by triplicate in 1 L polypropylene bottles and stored at -20°C until analysis. GLY was extracted from unfiltered water samples with a buffer solution (100 mM Na2B4O7•10H2O/100 mM K3PO4, pH=9) and derivatized with 9-fluorenylmethylchloroformate (1 mg/mL in acetonitrile). Afterwards samples were analyzed using liquid chromatography coupled to a tandem mass spectrometer (UPLC-MS/MS). The detection limit (LD) was 0.1 μg/L and the quantification limit (QL) was 0.5 μg/L. The rainfall regime was obtained from the database of INTA Balcarce. GLY was detected in 92.3% of the analyzed samples. In the US site, were GLY is regularly applied, the highest GLY concentration was registered in October (2.15 ± 0.16 μg/L); from November to June, the GLY levels decreased from 1.97 ± 0.17 μg/L to

    decontamination, dermatology, nuclear weapons effects simulation, and graffiti control. It was readily apparent that the customary diffusion of advanced technologies from science and industry into the art conservation field had been reversed. In this paper we trace the migration and adaptation of radiation divestment developments in art conservation to numerous applications in science, industry, and consumer products. Examples described include the robotized hybrid "Flashjet" aircraft paint stripping system, the "Novotronic" anthrax remediation installation in the Pentagon Building, the InTa automated graffiti removal system employing a carbon dioxide TEA laser, the Bellalite body hair removal product incorporating flashlamp technology, and the Foodco line of optical radiation products for the sterilization of food products. The Foodco products are also applied to the sterilization and/or pasteurization of beverages and beverage containers. A similar device has been adapted to seafood irradiation in order to increase shelf life, as well as for the ablative removal of skin and scales. The Goodyear Tire and Rubber Company, to etch logos and identification information into the sidewalls of pneumatic tires, also developed a flashlamp-based ablation technology. The founders of the CYMER Corporation applied UV irradiation technology to the manufacture of high-performance integrated circuits (viz., memory chips, etc.) In several instances former CASS students and Visiting Fellows consciously adapted the above-learned art conservation methodologies to still other purposes. Thus, these examples of technology transfer may be termed: "Art in the service of Science." Alternatively, it is evident that many associated innovations developed from independent activities, unconnected serendipity, or through the normal diffusion of information and knowledge across disciplines.

The INES Principal Centre is at the LAEFF, owned by INTA, the Spanish National Institute for Aerospace Technology. This centre, with a data mirror at the CADC in Victoria (Canada), holds the complete database and provides information not available from national hosts. So far 17 national hosts (listed below) have come online. Together they form with the Principal Centre an efficient and highly reliable distribution system for the community. The whole process of data retrieval is fully automated and totally transparent to the end user. This distributed structure avoids localised connectivity problems and guarantees availability of data. The release of INES will be celebrated on 21 March with a ceremony at the ESA/VILSPA Satellite Tracking Station in Villafranca near Madrid (see attached agenda and accreditation form). At various other national hosts the release of the INES system will also be celebrated by local academic and demonstration events on different dates. FOOTNOTE ON IUE SATELLITE The ESA/NASA/UK IUE spacecraft, launched in January 1978, became the first space observatory facility available to the whole astronomical community. It marked the beginning of UV astronomy, a field for which space telescopes are essential because UV light does not reach the Earth's surface. By the time IUE was switched off, in September 1996 --14 years later than originally planned -- IUE had changed the view astronomers had of the universe. Among many other findings, IUE discovered the auroras in Jupiter; detected for the first time the halo in our galaxy --a large amount of very hot matter in the outskirts of the Milky Way (the halo); and measured the size of a black hole in the core of an active galaxy.

    challenge. Also, we present measurements carry out at the Marambio Antarctic Base (64° 14' S; 56° 37' W, 197 m asl) during the months of January - February of 2008, using the ERO-DOAS. The NO2 and O3 VCD are derived from solar spectra acquired during the twilights (zenithal angles between 87° - 92° ), using the DOAS (Differential Optical Absorption Spectroscopy) technique. The biggest contribution to these spectra comes from the stratosphere, atmosphere layer that we want to study. The analysis is carried out by solving the Beer-Lambert-Bouger (BLB) law for all the atmospheric absorbers and a quasi-continuous wavelength range. The algorithm minimizes the fitting residuals to the BLB law, having as unknown the slant column density of the species to determine. The effects of Rayleigh and Mie scattering, fluorescence and most of the Raman scattering are accounted for and subtracted out using a high-pass polynomial filter. We compare the data acquired by our DOAS system with co-located measurements performed with EVA, a visible absorption spectrometer operated by the Instituto Nacional de Técnica Aeroespacial (INTA), Spain. Additionally, a comparative study is presented among the ground-based signals and those obtained by the instrument OMI (AURA satellite). The bigger mistake sources associated with the comparison between AURA satellite observations and those carried out from earth are: a) NOx daily cycle, b) NO2 natural variability, and c) NO2 tropospheric sensibility. In the case of Marambio, it hasn't relevance since it is non polluted places and the tropospheric NO2 level is very low. We observe that the NO2 has a strong photochemical variability during the day. This variability is associated with the solar cycle, the NOx vertical distribution, the temperature in the high layers of the atmosphere and sometimes (in high latitudes) of other active species.

    The paper reports a critical analysis of the thermal inertia approach to map surface soil water content on bare and sparsely vegetated soils by means of remotely sensed data. The study area is an experimental area located in Barrax (Spain). Field data were acquired within the Barrax 2011 research project. AHS airborne images including VIS/NIR and TIR bands were acquired both day and night time by the INTA (Instituto Nacional de Técnica Aeroespacial) between the 11th and 13rd of June 2011. Images cover a corn pivot surrounded by bare soil, where a set of in situ data have been collected previously and simultaneously to overpasses. To validate remotely sensed estimations, a preliminary proximity sensing set up has been arranged, measuring spectra and surface temperatures on transects by means of ASD hand-held spectroradiometer and an Everest Interscience radiometric thermometer respectively. These data were collected on two transects: the first one on bare soil and the second from bare to sparsely vegetated soil; soil water content in both transects ranged approximately between field and saturation values. Furthermore thermal inertia was measured using a KD2Pro probe, and surface water content of soil was measured using FDR and TDR probes. This ground dataset was used: 1) to verify if the thermal inertia method can be applied to map water content also on soil covered by sparse vegetation, and 2) to quantify a correction factor of the downwelling shortwave radiation taking into account sky cloudiness effects on thermal inertia assessment. The experiment tests both Xue and Cracknell approximation to retrieve the thermal inertia from a dumped value of the phase difference and the three-temperature approach of Sobrino to estimate the phase difference spatial distribution. Both methods were then applied on the remotely sensed airborne images collected during the following days, in order to obtain the spatial distribution of the surface soil moisture on bare soils and

    Heavy metals come from anthropogenic sources, agricultural and industrial, constitute a danger to aquatic biota and are used as an indicator of environmental deterioration. In agroecosystems that use pesticides, surface accumulation occurs by drift and runoff at lower levels of land that are appropriate spaces for the anurans' reproductive activities. Thus, heavy metals usually accumulate in surface sediments and generate an environment of chronic toxicity. The study was carried out at the Experimental Agricultural Station INTA Salta, Cerrillos, pcia. Of Salta, located at 24 ° 53'45''South and 65 ° 27'51''West at a height of 1240 meters. The annual average temperature is 23.8 ° C, the annual variation of the average temperature, corresponds to the "continental" type, with the maximum in the month of December and the minimum in June. The average annual temperature of the soil at 0.10 m. Of depth is 20.4 ° C. The annual distribution of the precipitations indicates the existence of a rainy season between October and April, that concentrates 90% of the precipitations and another one dries the rest of the year, with 720 mm. Of annual rainfall. The soils are of little development of horizons, corresponding to Inceptisols, Ustocrept udico, Series Cerrillos, of alluvial origin, well drained, developed on medium to fine textures, free to loamy loam, poor in organic matter and nitrogen. Soils of fluvio lacustrine origin, rich in silt and weak aggregation. Amphibians have been able to exploit the resources provided by agroecosystems and remain in a metapopulation system within an altered landscape. However, there is a tendency to decrease the density and diversity of amphibians in highly disturbed areas. Some authors suggest that changes in the patterns of amphibian diversity that inhabit agricultural landscapes allow inferring the depopulation of species less tolerant to environmental transformation associated with intensive and sustained agricultural activities over

    samples from different depths in the field for microor-ganism's enrichment. First results report enrichment in several inoculated media including some specific for heterotrophic aerobic bacteria, anaerobic chemolithotrophic and methanogen bacteria. Two different molecular methods are being used for microbial determination: "In situ" hybridizitation (was used for microbial determination and cell counting also) and 16S rRNA genes amplification, cloning and sequencing. First results in cell counting determined a population density gradient vs. depth. Second case: studying Atacama Desert: Habitability studies in the Atacama Desert were developed by the selection of a 36 square meters area where an atmospheric station was installed. The following parameters were measured: UV radiation, atmosphere temperature, ground temperature at three different depths, wind direction. Sam-ples at the pre-selected depths were taken in order to develop microbiological studies in the laboratory. Interesting results that will be presented at the COSPAR session were obtained with decreasing levels of life presence along the core profile.

    As a G protein-coupled receptor, the role of galanin receptor 2 (GalR2) has been studied extensively, but its transcriptional regulation mechanism is still unknown. In this study, 5'- upstream promoter sequence (spanned from -1121 to -1 bp) of human GalR2 gene and its three deletion segments were isolated and cloned inta the pGL3-Basic vector. Carresponding plasmids were named as pGL3-B-1121, pGL3-B-922, pGL3-B-521 and pGL3-B-200, respectively. Those four reporter plasmids were transfected into SK-NSH cells, and luciferase activities were measured. The results showed that deletion of the region between -1121 to -922 bp resulted in a significantly increased activity compared with pGL3-B-1121, indicating the presence of negative elements in this region. Moreover, it was also found that the Ga/R2 promoter had many putative transcription factor binding sites by using online software TESS, such as Sp1, AP-1, AP-2,NF-1, YY1 and ERα, suggested that those elements might be involved in transcriptional regulation. In conclusion, this study provides important clues for elucidating the transcriptional regulation mechanisms of the GalR2 gene.%人甘丙肽2型受体(GalR2)作为G蛋白偶联受体,其功能已被广泛研究,但GalR2基因的转录调控机制尚不明确.我们利用聚合酶链式反应(polymerase chain reaction,PCR)方法扩增人GalR2基因上游1121bp的片段,再通过PCR方法将其缺失成3段长度不等的片段,然后分别将其克隆到荧光素酶报告基因载体pGL3-Basic中,并将相应的质粒命名为pGL3-B-1121、pGL3-B-922、pGL3-B-521和pGL3-B-200;通过荧光素酶活性分析检测不同长度的GalR2基因启动子在入神经母细胞瘤细胞(SK-N-SH)中的活性,发现GalR2基因上游1121 bp区段具有明显的转录活性,缺失-1121到-922bp区域引起启动子活性的明显增高,暗示该区域存在负调控元件;利用TESS在线软件分析GalR2基因上游序列,发现该基因启动子含有Spl、AP-1、AP-2、NF-1

    Full Text Available Vid Pedagogiska institutionen vid Umeå universitet har nätutbildningen expanderat kraftigt under de senaste två och ett halvt åren, då institutionen började ge fristående helfartskurser i pedagogik via Internet. Vårterminen 2008 läste cirka 60 studenter och inför varje termin har sedan studenttillströmningen ökat, för att under våren 2010 uppgå till 240 studenter. Hösten 2008 infördes, med stöd av interna utvecklingsmedel, examinerande portfoliouppgifter på samtliga nätbaserade kurser med målsättningen att möta de utmaningar som både formen (nätundervisning och den utökade och heterogena studentgruppen innebar. Syftet var att stärka studenternas förmåga att synliggöra sitt eget lärande, samt att minska anonymiteten mellan lärare och student. Uppgifterna var av självreflekterande karaktär där studenterna uppmanades att relatera det egna lärandet till kursinnehållet och att exempelvis identifiera framtida tillämpningsområden inom studier och arbetsliv. Studenterna fick under terminen individuell återkoppling av en och samma lärare. Intentionen med återkopplingen var bland annat att guida och uppmuntra studenterna till att inta ett personligt förhållningssätt till kursinnehållet. I artikeln argumenteras det för att portfoliometodik i flera avseenden kan sägas harmoniera väl med ett rådande synsätt på examination där ett sociokulturellt synsätt på lärande dominerar och livslångt lärande och självständighet framhålls som eftersträvansvärt. Detta medför att, det både utifrån ett student- och ett lärarperspektiv, kan kännas naturlig och relevant att använda portfolio som examinationsform inom nätutbildning. Samtidigt är det viktigt att problematisera och kritiskt reflektera över portfoliometodik som examinationsform och de förhållningssätt och ideal som skapas, vilket görs i artikeln med hjälp av en Foucaultinspirerad tolkningsram.

    During the last decade one of the most developed topics in environmental studies was the effect of global climate change. This has been shown to be especially pronounced in northern regions, having an important influence on the subsequent transformation of frozen soil distribution and potential permafrost degradation. In West Siberia such studies are especially important with the prospect of plans for development of oil-gas fields (Yamal, Gydan and Kara Sea shelf). Presently the enterprises independently determine the necessary research for ecological control of the territory. Therefore, the Tyumen State Oil and Gas University (TSOGU) together with one of the leading gas enterprises "Nadymgasprom" started to create an observational network along the meridian transect of northern West Siberia (Yamal-Nenets administrative district). Observational network consists from a number of monitoring sites - Technical-Environmental permafrost Observatories (TEPO). The research complex includes temperature observations in boreholes (depths of 30) equipped with automatic systems for registration and data collection; seasonal field investigations on spatial distribution and temporal variability of the snow cover and vegetation and soil distribution. TSOGU and "Nadymgasprom" plan for the realization of long-term monitoring to obtain representative results on permafrost-climate interaction. At present there are three monitoring observatories located in the main landscape types and gas fields in use since 1972 (Medvezhye), 1992 (Yubileynoe) and in development (Harasavey). The next contribution to International Polar Year (2007-2008) will be renewal of one of the former monitoring sites (established in 1972) with a long-term period of observation and creation of a new site at the Yamal peninsula (Arctic tundra zone). At the last site the installation of an automatic Climate-Soil Station is being planned in the framework of the INTAS Infrastructure Action project with cooperation of

    the population; retrospective information on menstrual cycle characteristics; the determination of cut-points for all three outcome variables; and lacking information on some determinants of menstrual cycle characteristics, such as stress, physical activity, chronic diseases and gynecological disorders, thus confounding cannot be excluded. The generalizability of the study results is restricted to fertile women who manage to conceive and women who do not use oral contraceptives when getting pregnant or within 2 months before getting pregnant. To our knowledge only one previous epidemiological study has addressed the possible association between perfluorinated chemical exposure and menstrual disturbances. Though pointing toward different disturbances in cyclicity, both studies suggest that exposure to PFOA may affect the female reproductive function. This study contributes to the limited knowledge on effects of exposure to PFOA and PFOS on female reproductive function and suggests that the female reproductive system may be affected by environmental exposure to PFOA.

    New kind of planetary exploration mission for Mars is under development in collaboration between the Finnish Meteorological Institute (FMI), Lavochkin Association (LA), Space Research Institute (IKI) and Institutio Nacional de Tecnica Aerospacial (INTA). The Mars MetNet mission is based on a new semi-hard landing vehicle called MetNet Lander (MNL). The scientific payload of the Mars MetNet Precursor [1] mission is divided into three categories: Atmospheric instruments, Optical devices and Composition and structure devices. Each of the payload instruments will provide significant insights in to the Martian atmospheric behavior. The key technologies of the MetNet Lander have been qualified and the electrical qualification model (EQM) of the payload bay has been built and successfully tested. 1. MetNet Lander The MetNet landing vehicles are using an inflatable entry and descent system instead of rigid heat shields and parachutes as earlier semi-hard landing devices have used. This way the ratio of the payload mass to the overall mass is optimized. The landing impact will burrow the payload container into the Martian soil providing a more favorable thermal environment for the electronics and a suitable orientation of the telescopic boom with external sensors and the radio link antenna. It is planned to deploy several tens of MNLs on the Martian surface operating at least partly at the same time to allow meteorological network science. 2. Scientific Payload The payload of the two MNL precursor models includes the following instruments: Atmospheric instruments: 1. MetBaro Pressure device 2. MetHumi Humidity device 3. MetTemp Temperature sensors Optical devices: 1. PanCam Panoramic 2. MetSIS Solar irradiance sensor with OWLS optical wireless system for data transfer 3. DS Dust sensor The descent processes dynamic properties are monitored by a special 3-axis accelerometer combined with a 3-axis gyrometer.

    communities. The main conservation conflict occurs when the solitary boulder monuments or open boulder expositions (e.g. V. Intas' Museum of Boulders in Mosedis, the Geology Museum in Vievis) are concerned. These expositions are supposed to serve a basis for geological science and education; however they are almost completely overgrown. Attempts to clean the boulders were met by general public and some scientists rather negatively and caused several conflicts. A wave of negative opinions appeared in media after the second largest boulder Puntukas was cleaned by compressed water streams. Several problems are concerned. First of all, both chemical and mechanical cleaning not only will remove lichens and other cryptogams, but may be damaging to a boulder or to environment and wildlife. The measures should be taken with utmost care, and lichen species as well as stone surfaces are to be examined before applying any treatment. Another problem is to convince general public, caretakers and scientists that the overgrown stone surfaces should be cleaned. Some botanists, foresters, environmental people would prefer to let the nature to do its work and to cover stony surfaces with vegetation. Therefore, in conflict cases, expert opinions, both botanical and geological should be addressed. This is a contribution to the Open Access Centre activities

    The appearance of Supercooled Large Drops (SLD) can give way to icing aircraft. In these cases, atmospheric icing causes an unusual loss of support on the aircraft due to the rapid accumulation of ice on the wings or measurement instruments. There are two possible ways that SLD can be formed: The first is through a process called "warm nose", followed by "resupercooling". This process is usually associated with the entrance of warm fronts. The second possibility is that drops are formed by the process of condensation, and they grow, to sizes of at least 50 µm through processes of collision-coalescence, in environments with temperatures inferior to 0°C at all times, but without being able to produce a freezing process. Some authors point out that approximately 75% of gelling precipitation events are produced as a consequence of this second situation. Within the framework of the TECOAGUA Project, a series of scientific flights were performed in order to collect data in cloud systems capable of producing precipitation during the winter period and their capacity to create environments favorable to "icing aircraft". These flights were carried out making use of a C 212-200 aircraft, belonging to the National Institute of Aerospatial Techniques (INTA), with a CAPS installed. On 1 February 2012, the C 212-200 aircraft took off from the airport in Torrejón de Ardoz (Madrid), flying about 70 km to stand upright on the northern side of the Central System, finding itself at a flight level of 3500 m, an elevated concentration of SLD at temperatures around -12°C, with liquid water content up to 0.44 g/m3, which provoked the accumulation of ice on the outline of the aircraft's wings, which required a cancellation of the flight. Surrounding the flight area, a microwave radiometer (MWR) was installed. An area of instability between 750 hPa and 600 hPa was identified in the vertical MWR profiles of temperature and humidity during the hour of the flight. It is mainly in this

    This article presents a detailed analysis of the sub-mesoscale transport processes in the Strait of Gibraltar. The interest is focussed on the Camarinal Sill region, and special attention is paid to the across-strait transport processes, the divergences and convergences in the central zone, and the small-scale circulation patterns along the northern coastal margin. The analysis is based on high-resolution (7 m) SST images acquired by an air-borne hyper-spectral scanner, and has been complemented with a rhodamine-release experiment, continuous thermo-salinograph records, acoustic Doppler current (ADCP) profiles from both moorings and vessel-mounted experiments, and numerical modelling. It is deduced from the analysis that the coupling between the upwelling processes, induced by the internal tide and the generation of large-amplitude internal waves, and the cyclonic eddies formed on the coastal margin, seems to be the mechanism that explains the chlorophyll maxima frequently found on the coastal margin of the studied area. Further, as a consequence of the small-scale patterns of circulation induced by the internal waves, the suspended substances are displaced from the coastal margins toward the central zones and later are carried by the westward current toward the convergence zones created by the internal waves, where they may be retained and accumulate. Then, in the eastward phase of the tidal current over the Camarinal Sill, these nuclei of concentrated substances (nutrients, chlorophyll, and plankton) are transported toward the Alboran Sea, where they must contribute, in part, to the primary productivity there. High-resolution (7 m) SST images acquired by an Airborne Hyper-spectral Scanner (AHS) provided by the Spanish Institute of Aerospace Techniques (INTA). Measurements made along vessel transects crossing the studied zone, of current velocity and echo-intensity profiles acquired by ADCP, and sea surface temperature, salinity and released rhodamine (see Fig. 1

    De la Torre Noetzel, Rosa

    Abstract Space Verification Tests (SVT) are necessary for selection of the most promising biological organisms for flight experiments in Low Earth Orbit or other space destinations: Simulation of sample assembly, exposure to expected space parameters and sample disassembly are significantly advanced by such tests, will be performed with this tests, allowing post-analysis of the exposed biological material and thus a deeper understanding of the individual and synergistic effects of space. In this work we present the results obtained with the lichen species Circinaria gyrosa after the SVT 2 run-2 tests concerning the EXPOSE-R2 Mission Preflight Test Program, performed at the planetary and space simulation facilities at DLR (Deutsches Zentrum für Luft- und Raumfahrt, Cologne, Germany) [1], from October 2013 to January 2014. This vagrant lichen species was collected at the steppic highlands of Central Spain and defined as “astrobiological model system” due to previous test at space missions (BIOPAN-6, Foton M-3) [2, 3], Therefore, C. gyrosa is part of the BIOMEX experiment (Biology and Mars Experiment, ESA) [4] which will be exposed from July 2014 to January 2016 on board of EXPOSE R2 on the International Space Station. C. gyrosa was exposed at DLR to simulated space- and Mars parameters: a) space vacuum 10-5 Pa, space UV-radiation (200-400 nm, fluence of 12 months mission = 5 x 105 kJm-2) and temperature fluctuations (-25 ºC to 10 ºC); b); Mars Simulated CO2 atmosphere, Mars pressure of 103 Pa, Mars UV-radiation (200-400 nm), and temperature fluctuations (-25 ºC to 10 ºC). In line with the lichen's well studied adaptations to harsh environmental conditions [5, 6] we observed a high recovery- and resistance capacity of C. gyrosa which was demonstrated after a 72 hours re-activation process of in the UV-Radiation and Bioclimatology Laboratories of INTA (Atmospheric Research and Instrumentation, Dept.

    . Our new late-type M discoveries include 49 subdwarfs, 25 extreme subdwarfs, six ultrasubdwarfs, one subdwarf/extreme subdwarf, and two dwarfs/subdwarfs. In addition, we discovered three early-L subdwarfs to add to the current compendium of L-type subdwarfs known to date. We doubled the numbers of cool subdwarfs (11 new from SDSS vs. 2MASS and 50 new from SDSS vs. UKIDSS). We derived a surface density of late-type subdwarfs of 0.040 per square degree in the SDSS DR7 vs. UKIDSS LAS DR10 cross-match (J = 15.9-18.8 mag) after correcting for incompleteness. The density of M dwarfs decreases with decreasing metallicity. We also checked the Wide Field Survey Explorer (AllWISE) photometry of known and new subdwarfs and found that mid-infrared colours of M subdwarfs do not appear to differ from their solar-metallicity counterparts of similar spectral types. However, the near-to-mid-infrared colours J-W2 and J-W1 are bluer for lower metallicity dwarfs, results that may be used as a criterion to look for late-type subdwarfs in future searches.

    and demonstrate a major juvenile input to their genesis. High Mg, Cr and Ni abundance in sanukitoids are interpreted either as result of the direct mantle melting (Stern &Hanson, 1991; Hattory et al., 1996, Smithies &Champion, 2000) or to be the product of the mixing between slab melt and the mantle wedge (Rapp &Shimizu, 1996, 1997, Rapp et al., 1999) So, the occurrence of the sanukitoids in the Karelia evidences the mantle influence in the late Archaean crust-forming events. The positive initial Epsilon Nd values indicate a source with long-term LREE depletion relative to chondrites. On the other hand the sanukitoids have a high LREE concentrations and as result a low 147Sm/144Nd ratio (0.06-0.11). High LREE, Ba, Sr and P (LILE) abundance in sanukitoids cannot be explained through crustal contamination because the average Archaean crust (Taylor &McLennan, 1985) has a smaller concentrations of these elements then sanukitoids. Some of the researchers try to explain the sanukitoids LILE enrichment by the addition of the LILE component of a fluid or melt through the metasomatism of their source region in subducting environments (Stern &Hanson, 1991; Hattory et al., 1996, Shimoda et al., 1998). Another idea is that LILE enrichment is attributed to the extensive metosomatism of the sanukitoids mantle source region by addition of about 40% TTG-like melt during tectonic underplating (Smithies &Champion, 2000). In the case of the sanukitoids of the Central Karelia this enrichment was simultaneously or shortly prior to melting because the U-Pb zircon age and TDM are similar and initial Epsilon Nd values plot close to depleted mantle array (Nagler and Kramers, 1998). Older TDM and lower Epsilon Nd values of the sanukitoids of the West Karelia and margin parts of the Central Karelia appear to be attributed the incorporation of the older crust in their source region.

    Environmental Sciences) biannual Young Scientists' School (YSS) and international conferences [15]. These include lecture courses for young scientists, training sessions, invited lectures and thematic workshops (www.scert.ru/en/conferences/). The first event was organized in 2000, and thereafter each year 50-70 young scientists from Russia and the Commonwealth of Independent States participate in CITES and ENVIROMIS conferences. These events are organized to support multidisciplinary education, contain no parallel sessions, are composed of about 50% students, and all presentations are posted to assist future professional activity. In the first years, these activities were supported internationally (INTAS, the EC International Cooperation Program within FP5 and FP6); however, recent activities have been supported by the Russian Foundation for Basic Research, the RF Ministry of Education and Science and the SB RAS. Some results gained in the course of SIRS projects being carried out, and current challenges While some findings on regional climate dynamics were reported in the EGU 2009 NEESPI session and in manuscripts listed on the NEESPI website (www.neespi.org/science/NEESPI_publications.pdf), a majority of them have been published in Russian journals and are still unknown in the international climatic community. However, additional reports can be found in the Enviro-RISKS final scientific report [16], mainly in the third volume devoted to climate change, terrestrial ecosystems and hydrology (www.dmi.dk/dmi/sr08-05-3.pdf). We have already established that temperatures have increased, particularly in the winter in Eastern Siberia (0.5°/decade), and the number of frost days (~1 day yr-1) and growing season length has also increased (~1 day yr-1) [17, 18]. Even more troubling is the potential for these transient phenomena to manifest themselves as nonlinear reactions to ongoing climatic change [19]. There are three main scientific research challenges to the SIRS community, which
