    Fusarium wilt caused by the fungus Fusarium oxysporum f. sp. cubens (Foc) is the most serious disease that attacks banana plants. Salicylic acid (SA) can play a key role in plant-microbe interactions. Our study is the first to examine the role of SA in conferring resistance to Foc TR4 in banana (Musa acuminata L. AAA group, cv. Cavendish), which is the greatest commercial importance cultivar in Musa. We used quantitative real-time reverse polymerase chain reaction (qRT-PCR) to analyze the expression profiles of 45 genes related to SA biosynthesis and downstream signaling pathways in a susceptible banana cultivar (cv. Cavendish) and a resistant banana cultivar (cv. Nongke No. 1) inoculated with Foc TR4. The expression of genes involved in SA biosynthesis and downstream signaling pathways was suppressed in a susceptible cultivar and activated in a resistant cultivar. The SA levels in each treatment arm were measured using high-performance liquid chromatography. SA levels were decreased in the susceptible cultivar and increased in the resistant cultivar. Finally, we examined the contribution of exogenous SA to Foc TR4 resistance in susceptible banana plants. The expression of genes involved in SA biosynthesis and signal transduction pathways as well as SA levels were significantly increased. The results suggest that one reason for banana susceptibility to Foc TR4 is that expression of genes involved in SA biosynthesis and SA levels are suppressed and that the induced resistance observed in banana against Foc TR4 might be a case of salicylic acid-dependent systemic acquired resistance.

In this study, we report the molecular characteristics of NPR1E gene cloned from banana(Musa acuminate L. AAA group, cv. Cavendish)using a RACE-PCR-based strategy. MaNPR1E(accession number: KF582550) contained an open reading frame of 1 755 bp which encoded a polypeptide of 584 amino acids. Protein alignment showed that they contain the complete typical conserved BTB/POZ (BR-C, ttk and bab/Pox virus and Zinc finger)domain, ankyrin repeats and NPR1/NIM1 like defence protein C terminal, which belongs to a typical NPR1 protein. Phylogenetic analysis showed that the deduced amino acid sequences of MaNPR1E also have high similarity to PdNPR3 (XP_008808341.1) and EgNPR3 (XP_010914123.1) from Phoenix dactylifera and Elaeis guineensis, respectively.

    A simple Cavendish apparatus is described that allows measurement of the gravitational constant G and makes observable the gravitational attraction between commonplace objects. The apparatus consists of a torsion balance constructed from readily available materials, including lead bricks and fishing weights ("sinkers"). A computer program is used to determine the gravitational field at the location of the small mass due to a nearby lead brick, which allows students to gain experience with numerical methods. Experimental results obtained are compatible with the accepted value of G.

    The combined influence of maturation, ripening, and climate on the profile of bioactive compounds was studied in banana (Musa acuminata, AAA, Cavendish, cv. Grande Naine). Their bioactive compounds were determined by the Folin-Ciocalteu assay and high-performance thin layer chromatographic (HPTLC) method. The polyphenol content of bananas harvested after 400 degree days remained unchanged during ripening, while bananas harvested after 600 and 900 degree days exhibited a significant polyphenol increase. Although dopamine was the polyphenol with the highest concentration in banana peels during the green developmental stage and ripening, its kinetics differed from the total polyphenol profile. Our results showed that this matrix of choice (maturation, ripening, and climate) may allow selection of the banana (M. acuminata, AAA, Cavendish, cv. Grande Naine) status that will produce optimal concentrations of identified compounds with human health relevance.

  9. Margaret Cavendish's materialist critique of van Helmontian chymistry.

    2011-03-01

    A striking omission in the scholarship on the reception of the chymical philosophy of Jan Baptista van Helmont in England in the seventeenth century is the work of the mid-seventeenth-century natural philosopher Margaret Cavendish, Duchess of Newcastle. In her Philosophical Letters (1664), Cavendish offers an extended critique of Van Helmont's work (whose Ortus Medicince had recently been translated into English by John Sadler). In this paper, I compare Cavendish's criticisms with those of Robert Boyle in his Sceptical Chymist (1661). Both Boyle and Cavendish attacked Van Helmont for the obscurity of his chymical vocabulary and concepts, and attacked his seminalism. Although their critiques had much in common, they diverged in their attitudes to Van Helmont's experiments. As an opponent of the experimental philosophy, Cavendish had little interest in the quality of Van Helmont's experimental claims, whereas Boyle was critical of their unreplicability. I also try to show that the two writers had very different polemical agendas, with Boyle defending his vision of chymistry based on a corpuscularian natural philosophy, and Cavendish being as much concerned with establishing her religious orthodoxy as with defending the truth claims of her own materialist vitalism. For Cavendish, Van Helmont was an example of the dangers of mingling theology and natural philosophy.

    The Cavendish Laboratory is arguably the most famous physics laboratory in the world. Founded in 1874, it rapidly gained a leading international reputation through the researches of the Cavendish professors beginning with Maxwell, Rayleigh, J. J. Thomson, Rutherford and Bragg. Its name will always be associated with the discoveries of the electron, the neutron, the structure of the DNA molecule and pulsars, but these are simply the tip of the iceberg of outstanding science. The physics carried out in the laboratory is the central theme of the book and this is explained in reasonably non-technical terms. The research activities are set in their international context. Generously illustrated, with many pictures of the apparatus used and diagrams from the original papers, the story is brought right up to date with descriptions of the science carried out under the leadership of the very different personalities of Mott, Pippard and Edwards.

    Ethylene signal transduction initiates with ethylene binding at receptor proteins and terminates in a transcription cascade involving the EIN3/EIL transcription factors. Here, we have isolated four cDNAs homologs of the Arabidopsis EIN3/EIN3-like gene, MA-EILs (Musa acuminata ethylene insensitive 3-like) from banana fruit. Sequence comparison with other banana EIL gene already registered in the database led us to conclude that, at this day, at least five different genes namely MA-EIL1, MA-EIL2/AB266318, MA-EIL3/AB266319, MA-EIL4/AB266320 and AB266321 exist in banana. Phylogenetic analyses included all banana EIL genes within a same cluster consisting of rice OsEILs, a monocotyledonous plant as banana. However, MA-EIL1, MA-EIL2/AB266318, MA-EIL4/AB266320 and AB266321 on one side, and MA-EIL3/AB266319 on the other side, belong to two distant subclusters. MA-EIL mRNAs were detected in all examined banana tissues but at lower level in peel than in pulp. According to tissues, MA-EIL genes were differentially regulated by ripening and ethylene in mature green fruit and wounding in old and young leaves. MA-EIL2/AB266318 was the unique ripening- and ethylene-induced gene; MA-EIL1, MA-EIL4/Ab266320 and AB266321 genes were downregulated, while MA-EIL3/AB266319 presented an unusual pattern of expression. Interestingly, a marked change was observed mainly in MA-EIL1 and MA-EIL3/Ab266319 mRNA accumulation concomitantly with changes in ethylene responsiveness of fruit. Upon wounding, the main effect was observed in MA-EIL4/AB266320 and AB266321 mRNA levels, which presented a markedly increase in both young and old leaves, respectively. Data presented in this study suggest the importance of a transcriptionally step control in the regulation of EIL genes during banana fruit ripening.

It is located under the Gran Sasso massif, in central Italy, between the cities of L'Aquila and Teramo, 120 km far from Rome. It is the largest underground laboratory for astroparticle physics in the world and the most advanced in terms of complexity and completeness of its infrastructures. The scientific program at the Gran Sasso National Laboratories (Laboratori Nazionali del Gran Sasso, LNGS)is mainly focused on astroparticle, particle and nuclear physics. The laboratory presently hosts many experiments as well as R&D activities, including world-leading research in the fields of solar neutrinos, accelerator neutrinos (CNGS neutrino beam from CERN to Gran Sasso), dark matter, neutrinoless double-beta decay and nuclear cross-section of astrophysical interest. Associate sciences like earth physics, biology and fundamental physics complement the activities. The laboratory is operated as an international science facility and hosts experiments whose scientific merit is assessed by an international advisory Scientific Committee. A review of the main experiments carried out at LNGS will be given, together with the most recent and relevant scientific results achieved.

    Historical accounts of successful laboratories often consist primarily of reminiscences by their directors and the eminent people who studied or worked in these laboratories. Such recollections customarily are delivered at the celebration of a milestone in the history of the laboratory, such as the institution's fiftieth or one­ hundredth anniversary. Three such accounts of the Cavendish Laboratory at the University of Cambridge have been recorded. The first of these, A History of the Cavendish Laboratory, 1871-1910, was published in 1910 in honor of the twenty­ fifth anniversary of Joseph John Thomson's professorship there. The second, The Cavendish Laboratory, 1874-1974, was published in 1974 to commemorate the one­ hundredth anniversary of the Cavendish. The third, A Hundred Years and More of Cambridge Physics, is a short pamphlet, also published at the centennial of the 1 Cavendish.

    This talk is about an interaction between two 18th-century natural philosophers (physical scientists), Henry Cavendish and John Michell, and its most important outcome, the experiment of weighing the world (their name for it) using a torsion balance (our name for it). Michell was the most inventive of the 18th century English natural philosophers, and Cavendish was the first of his countrymen to possess abilities at all comparable with Newton's. By their interests and skills, they were drawn to one another. Both were universal natural philosophers, equally adept at building scientific instruments, performing experiments, constructing theory, and using mathematics; both had a penchant for exacting, quantitative work. Both also had fitful habits of publication, which did not begin to reveal the range of their work, to the mystification of later scientists and historians. Late in life, Cavendish and Michell turned their attention to the force that Newton had examined most completely, a singular triumph of his natural philosophy, the force of universal gravitation. Over the course of the 18th century, abundant evidence of attraction had been gathered from the motions of the earth, moon, planets, and comets, phenomena which span the intermediate range of masses, sizes, and distances. But in three domains of experience, involving the extreme upper and lower limits of masses and dimensions, the universality of gravitation remained an article of faith. These were the gravity of the ``fixed'' stars, the mutual attraction of terrestrial bodies, and the gravitation of light and other special substances. Michell took on himself the task of deducing observable consequences from each of these prospective instances of universal gravitation. Cavendish encouraged Michell, and he followed up the resulting observational and experimental questions. The experiment of weighing the world was the last experiment Mitchell planned and the last experiment Cavendish published. The capstone of

    Full Text Available In teaching mathematical statistics it is desirable that students of engineering and natural sciences could study the methods of statistical processing based on data of real experiments. Conditions for these experiments are of critical importance to justify the application of statistical methods.The article considers a classic Henry Cavendish’s experiment to determine a mean density of the Earth from this point of view. The article gives a detailed description of the experimental Cavendish’s setup, ideas, his experiments are based on, and a method to determine the values used for assessment of the mean density of the Earth. It also concretizes the equation of a pendulum model with friction on which Cavendish implicitly (and neglecting a friction relied.It is shown that the formal use of methods of mathematical statistics is not always justified. Detailed records of all experiments, published by Cavendish, enable us to study these data in terms of mathematical statistics, convince us of their statistical inhomogeneity and impossibility to construct a confidence interval to estimate accuracy.The article proposes an alternative way for processing Cavendish's data implicitly using the pendulum model equation with friction to reduce an effect of systematic errors and improve matching the Cavendish results with modern data.

    This article explores Margaret Cavendish's depictions of alchemy, witchcraft and fairy lore in her scientific treatise Philosophical Letters and in fictional texts from Natures Pictures and Poems and Fancies. Though Cavendish was a dedicated materialist, she appropriates theories of magic from early modern science and folklore into her materialist epistemology. As Cavendish draws upon a fusion of early modern conceptions of magic, she creates a radical theory of matter which not only challenges patriarchy and binary oppositions, but also explores the plurality and mystery that can exist within an infinitely complex material world.

    As part of a study to understand the molecular basis of fruit ripening, this study reports the isolation and characterization of a banana cytochrome P450 (P450) cDNA, designated as MAP450-1, which was associated with fruit ripening of banana. MAP450-1 encoded a single polypeptide of 507 amino acid residues that shared an overall identity of 27-45% with that of several plant P450s, among which MAP450-1 was most related phylogenetically to the avocado P450 CYP71A1. The polypeptide that possessed residue domains conserved in all P450s was classified as CYP71N1. Expression of CYP71N1 varied greatly between banana organs. Transcripts were detected only in peel and pulp of the ripening fruit and not in unripe fruit tissues at all developmental stages or other organs (root, leaf, ovary and flower). During ripening, transcripts were barely detectable in pre-climacteric and climacteric fruits but, as ripening progressed, they began to accumulate and reached a maximum in post-climacteric fruits. CYP71N1 expression in pre-climacteric fruit could be upregulated by exogenous application of ethylene (1-5 ppm) and treatment of overripe fruit with exogenous sucrose (50-300 mM) but not glucose downregulated the expression. These results indicate that P450s may not play a role in fruit development and its expression is associated with ripening, which may be regulated, in part, by ethylene and/or sucrose, at the transcript level.

  12. No actual measurement ... was required: Maxwell and Cavendish's null method for the inverse square law of electrostatics

    CERN Document Server

    Falconer, Isobel

    2016-01-01

    In 1877 James Clerk Maxwell and his student Donald McAlister refined Henry Cavendish's 1773 null experiment demonstrating the absence of electric charge inside a charged conductor. Such absence of charge was a mathematical prediction of the inverse square law, and both Cavendish and Maxwell took the experiment as verifying the law. However, Maxwell had previously expressed absolute conviction in the law, based on results of Faraday's. So what was the value to Maxwell of replicating Cavendish's experiment? This paper examines the mathematical and instrumental contexts of Maxwell's experiment. It situates the experiment in an assessment of the status of the inverse square law in the 1870s based on textbooks, Maxwell's drive to develop both an electrical programme and a "doctrine of method", and an investigation of the understanding of null methods in the 1870s. It demonstrates that he had previously shifted the evidential context of Faraday's work to suit his aims. It concludes that the experiment served both a...

    Microbiological and physicochemical factors affecting the incidence of Aspergillus section Flavi in dried Cavendish banana (Musa cavendishii) chips production in Southern Philippines were examined. The average counts of Aspergillus section Flavi (AFC) in fresh and dried Cavendish bananas from 10 production batches of the Philippine Agro-Industrial Development Cooperative in Davao del Norte, Southern Philippines were 1.2 x 10(2) and 1.6 x 10(2) cfu/g, respectively. Isolates from both samples were identified to be Aspergillus flavus based on spore type and conidial structure of isolates. An increasing trend in the AFC of Cavendish bananas was observed during dried banana chips processing. Variability in the AFC between production batches was attributed to differences in aerobic and fungal populations and physicochemical characteristics of the fruits, peel damage of the raw materials, concentration of AFC in the air and food-contact surfaces of the production area, and temperature and relative humidity (RH) conditions of the environment during production and storage. Physicochemical characteristics of Cavendish bananas from the receipt of raw materials up to the first day of drying were within the reported range of values allowing growth and toxin production by aflatoxigenic fungi. Air-borne AFC varied depending on the section of the production area examined. The close proximity of the waste disposal area from the production operation to the preparation, drying and storage areas suggests that cross-contamination, probably air-borne or insect-borne was a likely occurrence. The hands of workers were also identified as AFC sources. Results of this study highlight the need for the development of strategies to control aflatoxigenic fungi and aflatoxin contamination in Philippine dried Cavendish bananas.

    Shongwe, V. D.; Tumber, R.; Masarirambi, M. T.; Mutukumira, A. N.

    The banana is one of the most important fruit crops in the world. In terms of consumption, the banana fruit is ranked high yet there has not been much research particularly in relation to water requirements for propagules produced by tissue culture. In recent years, tissue culture banana planting material has become increasingly important due to its vigorous growth and high yields. The objective of this study was to investigate optimum soil water requirements of tissue-cultured banana. Dwarf Cavendish tissue-cultured plantlets grown in pots in a greenhouse were subjected to four irrigation regimes at 100% ETm, 85% ETm, 65% ETm, and 40% ETm. Plant parameters measured were leaf number, plant height, pseudo-stem girth, leaf length, leaf width, leaf area, leaf area index, leaf index, leaf colour, and plant vigour. Soil water potential measurements were also made over a three-month period. Differences between irrigating at 100% ETm and 85% ETm were not significantly ( P plant height, and plant height, compared to 65% and 40% ETm treatments. Pseudo-stem girth was highest from the 100% ETm compared to the other treatments. Economic yields of banana may be obtained with irrigation regimes ranging between 100% ETm and 85% ETm.

    Full Text Available Abstract Background Fusarium wilt, caused by the fungal pathogen Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4, is considered the most lethal disease of Cavendish bananas in the world. The disease can be managed in the field by planting resistant Cavendish plants generated by somaclonal variation. However, little information is available on the genetic basis of plant resistance to Foc TR4. To a better understand the defense response of resistant banana plants to the Fusarium wilt pathogen, the transcriptome profiles in roots of resistant and susceptible Cavendish banana challenged with Foc TR4 were compared. Results RNA-seq analysis generated more than 103 million 90-bp clean pair end (PE reads, which were assembled into 88,161 unigenes (mean size = 554 bp. Based on sequence similarity searches, 61,706 (69.99% genes were identified, among which 21,273 and 50,410 unigenes were assigned to gene ontology (GO categories and clusters of orthologous groups (COG, respectively. Searches in the Kyoto Encyclopedia of Genes and Genomes Pathway database (KEGG mapped 33,243 (37.71% unigenes to 119 KEGG pathways. A total of 5,008 genes were assigned to plant-pathogen interactions, including disease defense and signal transduction. Digital gene expression (DGE analysis revealed large differences in the transcriptome profiles of the Foc TR4-resistant somaclonal variant and its susceptible wild-type.

    Science.gov (United States)

    2015-12-01

    This paper investigates Margaret Cavendish's characterization of experimental philosophers as hybrids of bears and men in her 1666 story The Description of a New World, Called the Blazing World. By associating experimental philosophers, in particular Robert Hooke and his microscope, with animals familiar to her readers from the sport of bear-baiting, Cavendish constructed an identity for the fellows of the Royal Society of London quite unlike that which they imagined for themselves. Recent scholarship has illustrated well how Cavendish's opposition to experimental philosophy is linked to her different natural-philosophical, political and anthropological ideas. My contribution to this literature is to examine the meanings both of bears in early modern England and of microscopes in experimental rhetoric, in order to illustrate the connection that Cavendish implies between the two. She parodied Hooke's idea that his microscope extended his limited human senses, and mocked his aim that by so doing he could produce useful knowledge. The bear-men reflect inhuman ambition and provide a caution against ignoring both the order of English society and the place of humans in nature.

    The INFN Laboratory at Gran Sasso is a sanctuary for neutrinos. Located 963 metres over the sea level, it is protected by the 1400 metres of the rock of Gran Sasso mountain, next to the road tunnel of the same name, 120 km from Rome in Italy. It was from this underground location, ideal for receiving a high-energy neutrino beam from CERN, that first sprang the idea for the CNGS (CERN Neutrinos to Gran Sasso) project. However, an accident which occurred in one of the Laboratory's three experimental halls last August resulted in its temporary closure, leaving a question mark over the project's future.

In high rise buildings, difficulty of access by Extinction Services should be taken into account, as well as the impossibility of proceeding to make total evacuation. Consequently, it is necessary to design the building with exteriorization criteria, both vertical and horizontal and of protection of the structural elements, which make it possible to suffocate the fire and the partial evacuation of the occupants to independent neighboring sector.

    Cocco, A G

    2000-01-01

    OPERA (Oscillation Project with Emulsion-tRacking Apparatus) is a long-baseline experiment to search for vμ → vτ oscillations in the Gran Sasso laboratory. It will study the interactions of 20 GeV neutrinos produced at CERN to search for neutrino flavour oscillation over a distance of about 730 Km. The OPERA detector is designed to unambiguously observe the appearance of vτ in a pure vμ beam. The detector is based on a massive lead/nuclear emulsion target. Nuclear emulsions are exploited for the direct observation of the decay of the τ lepton, produced in vτ charged-current interactions. The discovery potential of OPERA is ultimately due to a very low background level and could therefore play a decisive role in the clarification of the experimental scenario.

    Spatial distribution of immatures of the banana skipper (Erionota thrax L.) and their parasitisms from three major parasitoids were studied in a Cavendish banana plantation from April 2004 to December 2004. Infestation levels and parasitism ofE. thrax life stages were recorded from bunched plants (BP), flowering plants (FP), preflowered plants (PF),broad leaf followers (BLF) and narrow leaf followers (NLF), as well as on well managed and poorly managed plants. Mean numbers of the immatures and numbers parasitized from the nine blocks in the plantation were fitted to four dispersion indices. Significant numbers of E. thrax immatures and those parasitized by Ooencyrtus erionotae, Cotesia erionotae and Brachymeria albotibialis were recorded from BLF and PF; no eggs were found on BP and FP. Although infestation was higher on well managed plants, only larval parasitism was significandy different. Three of the four indices indicated that eggs and larvae were random while all the indices showed pupae to be clumped. Parasitized eggs and pupae were clumped (4/4 indices) while 3/4 indices revealed a random pattern for parasitized larvae.

    Biosynthesis of metallic silver nanoparticles has now become an alternative to physical and chemical approaches. In the present study, silver nanoparticles (AgNPs) were synthesized from Cavendish banana peel extract (CBPE) and characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Atomic force microscopy (AFM), Field emission scanning electronic microscope (FESEM), Dynamic light scattering (DLS) and zeta potential (ZP). The AgNPs formation was confirmed by UV-visible spectroscopy through color conversion due to surface plasma resonance band at 430 nm. The effect of pH on nanoparticle synthesis was determined by adjusting the various pH of the reaction mixtures. The crystalline nature of nanoparticles was confirmed from the XRD pattern, and the grain size was found to be around 34 nm. To identify the compounds responsible for the bioreduction of Ag+ ion and the stabilization of AgNPs produced, the functional group present in Cavendish banana peel extract was investigated using FTIR. AFM has proved to be very helpful in determining morphological features and the diameter of AgNPs in the range of 23-30 nm was confirmed by FESEM. DLS studies revealed that the average size of AgNPs was found to be around 297 nm. Zeta potential value for AgNPs obtained was -11 mV indicating the moderate stability of synthesized nanoparticles. The antibacterial activity of the nanoparticles was studied against Gram-positive and Gram-negative bacteria. Biosynthesized AgNPs showed a strong DPPH radical and ABTS scavengers compared to the aqueous peel extract of Cavendish banana.

    The accessibility of fermentable substrates to enzymes is a limiting factor for the efficient bioconversion of agricultural wastes in the context of sustainable development. This paper presents the results of a biochemical analysis performed on six combined morphological parts of Williams Cavendish Lignocellulosic Biomass (WCLB) after steam cracking (SC) and steam explosion (SE) pretreatments. Solid (S) and liquid (L) fractions (Fs) obtained from SC pretreatment performed at 180°C (SLFSC180) and 210°C (SLFSC210) generated, after diluted acid hydrolysis, the highest proportions of neutral sugar (NS) contents, specifically 52.82 ± 3.51 and 49.78 ± 1.39%w/w WCLB dry matter (DM), respectively. The highest proportions of glucose were found in SFSC210 (53.56 ± 1.33%w/w DM) and SFSC180 (44.47 ± 0.00%w/w DM), while the lowest was found in unpretreated WCLB (22.70 ± 0.71%w/w DM). Total NS content assessed in each LF immediately after SC and SE pretreatments was less than 2%w/w of the LF DM, thus revealing minor acid autohydrolysis consequently leading to minor NS production during the steam pretreatment. WCLB subjected to SC at 210 °C (SC210) generated up to 2.7-fold bioaccessible glucan and xylan. SC and SE pretreatments showed potential for the deconstruction of WCLB (delignification, depolymerization, decrystallization and deacetylation), enhancing its enzymatic hydrolysis. The concentrations of enzymatic inhibitors, such as 2-furfuraldehyde and 5-(hydroxymethyl)furfural from LFSC210, were the highest (41 and 21 µg ml(-1), respectively). This study shows that steam pretreatments in general and SC210 in particular are required for efficient bioconversion of WCLB. Yet, biotransformation through biochemical processes (e.g., anaerobic digestion) must be performed to assess the efficiency of these pretreatments.

    The Large Millimeter Telescope/Gran Telescopio Milimetrico (LMT) project is a collaboration between the University of Massachusetts and the Instituto Nacional de Astrofisica, Óptica y Electrónica to build a 50 m diameter telescope that will have good efficiency at wavelengths as short as 1 mm. The LMT will have an overall effective surface accuracy of 70 micrometers and an ultimate pointing accuracy of better than 1 arcsec, and will thus be the largest millimeter-wavelength telescope in the world. The LMT site is Sierra Negra in the state of Puebla, at 4,640 meters above sea level in Central Mexico. At 18° 59' N latitude, it offers good sky coverage of both hemispheres. The normally low humidity will allow operation of the radio telescope at frequencies as high as 345 GHz. The LMT will make use of recent advances in structural design and active control of surface elements to achieve the required surface and pointing accuracy. At the site the alidade has been erected and the back structure for the main reflector has been assembled, while the monitor and control system has been successfully tested on another telescope. The schedule calls for acceptance tests in 2006. The initial complement of instruments will include a 32 element, heterodyne focal plane array at 3mm; a large format, focal plane bolometer array; a unique wide band receiver and spectrometer to determine the redshifts of primordial galaxies, and a 4 element receiver for the 1mm band. With its excellent sensitivity and mapping speed, the LMT/GTM will be a powerful facility for planetary science. In particular, it will enable key observations of comets, planetary atmospheres, asteroids and KBOs.

    Tryggve Gran grew up in an affluent family in Bergen, Norway. The German emperor, William II, often visited the families of his friends. Gran became a good skier, hence well prepared for Robert Scott's second expedition to the Antartic in 1910. Gran deeply regretted the Scott-Amundsen competition, and was cut off from the team heading for the South Pole. In 1913, Gran trained in England and France as an air pilot. On 30 July 1914 he became the first pilot to cross the North Sea from Scotland to Norway. He joined the Royal Air Force in 1916 under the pseudonym of Teddy Grant, passing himself off as a Canadian, and received the Military Cross for distinguished war service. During the Second World War, Gran was a member of Quisling's pro-German National Party. A commemorative stamp was issued in 1944 on the 30th anniversary of his North Sea flight, and a meeting held in his honour with Quisling and German officers present. In this article, the author discusses some psychological aspects of Tryggve Gran's choice of tasks and of his politics. Gran lost his father when he was only five and when he was 11 he was sent off to a pension in Switzerland for a year. Strongly ambivalent feelings from the oedipal period and from the latency may later have been released through hazardous activities, certainly with self-destructive aspects. His membership in Quisling's party might be seen in this context.

Brazil) plantlets under the static culture and substrate culture were 'compared. Four nutrient solutions including Hoagland solution, Murashige and Skoog (1/2MS) solution, BXM solution and RSYY solution were used to culture banana plantlets, which grew in tap water or in substrate culture (pearlite as substrate). The data showed that banana plantlets grew well in the four tested nutrient solutions, and there was a significant increase in biomass of the banana plantlets grew in static nutrient solution over that in tap water. Among the four nutrient solutions, the biomass of the banana plantlets that grew in BXM solution was next to that in substrate (pearlite) culture, and was significantly more than that in Hoagland solution, 1/2MS solution and RSYY solution. The indexes such as plant height and leaf area of banana plantlets that grew in BXM solution were largest among the four nutrient solutions, and then that grew in Hoagland solution, RSYY solution and MS solution reduced in turn. In conclusion, the banana plantlets grew best in BXM solution among the four nutrient solutions. So BXM solution is suggested, when growing banana plantlets in water culture.

    Under the shelter of 1400 m limestone rock the Gran Sasso underground laboratories in the Apennines (110 km north-east of Rome at a turn-off inside the Gran Sasso motorway tunnel) were designed for running large experiments in the field of neutrino, particle and astrophysics by international collaborations. These experiments have in common the basic requirement to be capable to detect very rare events like e.g. neutrino interactions and double beta decays. Due to this their permanent demands for selecting radiopure materials have led to the equipping of a Ge detector laboratory - at present with 6 large detectors. (orig./DG)

    1990-08-01

    Three major eolian sand populations can be recognized in the Gran Desierto sand sea of northwestern Mexico by using spectral data from the Landsat thematic mapper in conjunction with textural and mineralogical studies of surface sands. Each sand population has distinct textural, mineralogic, and spectral properties that can be related to sand-dune morphology and position with reference to source areas and transport paths of the sands. The oldest eolian sediment in the sand sea was derived from the early to middle Pleistocene Colorado River that flowed through the area of the western Gran Desierto. Subsequent inputs of eolian sands came from the area of the present Colorado River valley and the coast south of the sand sea. The spatial and temporal pattern of eolian deposition in the region has been controlled by Quaternary tectonic and climatic changes, resulting in the episodic input and deposition of sand.

    Objetivos: evaluar la prevalencia de trastornos de la conducta alimentaria en estudiantes con edades comprendidas entre los 12 a 20 años mediante medidas estandarizadas. Material y métodos: se seleccionaron al azar un total de 1342 participantes de centros educativos de la isla de Gran Canaria, España. Se empleó un diseño transversal de dos fases que incluía un primer cuestionario de cribado (EAT-40 con el punto de corte establecido en 20) y una entrevista clínica semi-estructurada (EDE). También se evaluaron variables sociodemográficas y el estado ponderal de los alumnos. Resultados: en el año 2013 estudiamos a participantes de 15 centros educativos de Gran Canaria. En la primera fase se halló una prevalencia de riesgo de 27,42% (33% de mujeres, 20,6% de hombres). En la segunda fase, 538 participantes accedieron a ser evaluados mediante entrevista clínica (285 en riesgo, con altas puntuaciones en el EAT; 253 seleccionados del grupo sin riesgo). La prevalencia global de trastorno de la conducta alimentaria fue de 4,11% (5,46% de mujeres, 2,55% de hombres). Empleando los criterios diagnósticos del DSM-IV-TR, la prevalencia para la anorexia nerviosa fue de 0,19%, para la bulimia nerviosa de 0,57% y para el trastorno de la conducta alimentaria no especificado de 3,34%. Conclusiones: la prevalencia diagnóstica de trastornos de la conducta alimentaria en Gran Canaria es similar a la del resto de España. Sin embargo, la prevalencia de riesgo de desarrollar dichos trastornos es especialmente elevada en Gran Canaria, teniendo en cuenta los datos de estudios tanto nacionales como internacionales.

Since planting, each three to four leaves sprouted, three plants per variety were sampled, each corresponding to a repetition. These were separated into its different organs and the total dry matter was estimated. Each cv. was analyzed on a growth curve. The dry matter accumulation on both cvs. is adjusted to the typical sigmoid curve of the plant growth. In the exponential phase, the corm was the main source of assimilates for the development; while in the lineal and senescence phase, the pseudo-stem and leaves were the reservoir organs; when the bunch is formed, such reserves were sent to this drain. In general, while the development progressed, the vegetative organs did not show any dry matter lost, only reduction in the assimilates accumulation rate; unlike the bunch that from its emission kept a high rate, leading the fruit to represent, in the harvest season, almost 50% of the total dry matter of the plant.El estudio se realizó en la zona bananera de Urabá (Colombia; con los cvs. Gran Enano y Valery.

    Full Text Available fMRI studies showed that acupuncture could induce hemodynamic changes in brain networks. Many of these studies focused on whether specific acupoints could activate specific brain regions and were often limited to manual acupuncture at acupoints on the limbs. In this fMRI study, we investigated acupuncture's modulation effects on brain functional networks by electroacupuncture (EA at acupoints on the midline of abdomen. Acupoints Guanyuan (CV4 and Zhongwan (CV12 were stimulated in 21 healthy volunteers. The needling sensations, brain activation, and functional connectivity were studied. We found that the limbic-prefrontal functional network was deactivated by EA at CV4 and CV12. More importantly, the local functional connectivity was significantly changed during EA stimulation, and the change persisted during the period after the stimulation. Although minor differences existed, both acupoints similarly modulated the limbic-prefrontal functional network, which is overlapped with the functional circuits associated with emotional and cognitive regulation.

    Net tidal torque by the secondary on a misaligned accretion disk, like the net tidal torque by the Moon and the Sun on the equatorial bulge of the spinning and tilted Earth, is suggested by others to be a source to retrograde precession in non-magnetic, accreting Cataclysmic Variable (CV) Dwarf Novae systems that show negative superhumps in their light curves. We investigate this idea in this work. We generate a generic theoretical expression for retrograde precession in spinning disks that are misaligned with the orbital plane. Our generic theoretical expression matches that which describes the retrograde precession of Earths' equinoxes. By making appropriate assumptions, we reduce our generic theoretical expression to those generated by others, or to those used by others, to describe retrograde precession in protostellar, protoplanetary, X-ray binary, non-magnetic CV DN, quasar and black hole systems. We find that differential rotation and effects on the disk by the accretion stream must be addressed. Our a...

    The Gran Sasso National Laboratory of INFN (LNGS) is the largest underground laboratory for astroparticle physics in the world. Located in Italy between the cities of L'Aquila and Teramo, 120 km far from Rome, is a research infrastructure mainly dedicated to astroparticle and neutrino physics. It offers the most advanced underground facility in terms of dimensions, complexity and completeness of its infrastructures. LNGS is one of the four national laboratories run by the Istituto Nazionale di Fisica Nucleare (INFN). The scientific program at LNGS is mainly focused on astroparticle, particle and nuclear physics. The laboratory presently hosts many experiments as well as R&D activities, including world-leading research in the fields of solar neutrinos, accelerator neutrinos (CNGS neutrino beam from CERN to Gran Sasso), dark matter (DM), neutrinoless double beta decay (2β0ν) and nuclear cross-section of astrophysical interest. Associate sciences like earth physics, biology and fundamental physics complement the activities. The laboratory is operated as an international science facility and hosts experiments whose scientific merit is assessed by an international advisory Scientific Committee. A review of the main experiments carried out at LNGS will be given, together with the most recent and relevant scientific results achieved.

  6. A new proton spill from CERN to Gran Sasso

    CERN Multimedia

    CERN Bulletin

    2011-01-01

    Since 21 October, CERN has been sending a new type of neutrino beam to Gran Sasso. The new configuration is intended to allow the experiments to define the departure time of the neutrinos more accurately and thus check the previous results obtained using the nominal beam configuration.   The CERN Neutrino to Gran Sasso (CNGS) beam no longer operates using the standard beam time structure. Instead, a new type of proton pulse is being produced by CERN’s accelerators and sent to the graphite target to generate neutrinos. “We are now producing extremely short beam pulses,” explains Edda Gschwendtner, the physicist in charge of the CNGS secondary beam. “During a CNGS cycle we now have a LHC type bunched beam with four bunches, each about 2 ns long. Each bunch contains more than 2.5 x 1011 protons; bunches are spaced by 500 ns. In total, this makes about 1012 protons on target for each extraction from the SPS.” The CNGS beam was originally designed to m...

    When metal/semiconductor schotky barriers are not practical, an electrolyte/semiconductor interface can be used to make capacitance-voltage (C-V) measurements. The physics of such electrochemical C-V measurements will be described. Electrical properties of ZnO were measured by electrochemical C-V techniques and photovoltage spectroscopy using an Accent 4400 Electrochemical CV system. Specifically, the electrical behavior of a 0.1 M ZnCl2 electrolyte-ZnO interface has been investigated with attention to the electrolyte-ZnO interface's C-V dependence on carrier frequency.

    We studied banana lignocellulosic biomass (BALICEBIOM) that is abandoned after fruit harvesting, and assessed its biochemical methane potential, because of its potential as an energy source. We monitored biogas production from six morphological parts (MPs) of the "Williams Cavendish" banana cultivar using a modified operating procedure (KOP) using KOH. Volatile fatty acid (VFA) production was measured using high performance liquid chromatography. The bulbs, leaf sheaths, petioles-midribs, leaf blades, rachis stems, and floral stalks gave total biogas production of 256, 205, 198, 126, 253, and 221 ml g⁻¹ dry matter, respectively, and total biomethane production of 150, 141, 127, 98, 162, and 144 ml g⁻¹, respectively. The biogas production rates and yields depended on the biochemical composition of the BALICEBIOM and the ability of anaerobic microbes to access fermentable substrates. There were no significant differences between the biogas analysis results produced using KOP and gas chromatography. Acetate was the major VFA in all the MP sample culture media. The bioconversion yields for each MP were below 50 %, showing that these substrates were not fully biodegraded after 188 days. The estimated electricity that could be produced from biogas combustion after fermenting all of the BALICEBIOM produced annually by the Cameroon Development Corporation-Del Monte plantations for 188 days is approximately 10.5 × 10⁶ kW h (which would be worth 0.80-1.58 million euros in the current market). This bioenergy could serve the requirements of about 42,000 people in the region, although CH₄ productivity could be improved.

  9. Characterization of South African isolates of Fusarium oxysporum f.sp cubense from Cavendish banana

    Full Text Available Fusarium wilt, caused by the soil-borne fungus Fusarium oxysporum f.sp. cubense (Foc, is a serious vascular disease of bananas in most subtropical and tropical regions of the world. Twenty-four vegetative compatibility groups (VCGs and three pathogenic races have been identified in Foc, reflecting a relatively high genetic diversity for an asexual fungus. To characterise a South African population of Foc, a collection of 128 isolates from diverse geographic origins were isolated from diseased Cavendish bananas and subjected to VCG analysis and sequencing of the translation elongation factor 1-α (TEF gene region. The presence of mating type genes was also determined using MAT-1 and MAT-2 specific primers. VCG 0120 was established as the only VCG of Foc present in the South African population studied. Only the MAT-2 idiomorph was present in all the local isolates of Foc. A phylogenetic analysis of DNA sequences of the TEF gene region revealed that the South African isolates grouped closely with VCG 0120 isolates from Australia and Asia. These results suggest that the South African population of Foc was most likely introduced in a limited number of events and that it had spread with infected planting material within the country. The presence of only one mating type and the limited diversity in this pathogen render it unlikely to rapidly overcome disease management strategies involving host resistance.

    The conceptual technical design of the NGS (CERN neutrino beam to Gran Sasso) facility has been presented in the report CERN 98-02 / INFN-AE/98-05. Additional information, in particular an update on various neutrino beam options for the NGS facility, has been provided in a memorandum to the CERN-SPSC Committee (CERN-SPSC/98-35). In the present report, further improvements on the NGS design and performance, in particular new scenarios for SPS proton cycles for NGS operation and a new version of the NGS "high energy" neutrino beam for nt appearance experiments, are described. This new NGS reference beam is estimated to provide three times more nt events per year than the beam presented in the 1998 report. The radiological aspects of the NGS facility have been re-examined with the new beam design. An updated version of the construction schedule is also presented.

    Experimental observations and theoretical arguments at Galaxy and larger scales have suggested that a large fraction of the Universe is composed by Dark Matter particles. This has motivated the DAMA experimental efforts to investigate the presence of such particles in the galactic halo by exploiting a model independent signature and very highly radiopure set-ups deep underground. Few introductory arguments are summarized before presenting a review of the present model independent positive results obtained by the DAMA/NaI and DAMA/LIBRA set-ups at the Gran Sasso National Laboratory of the INFN. Implications and model dependent comparisons with other different kinds of results will be shortly addressed. Some arguments put forward in literature will be confuted.

    Full Text Available The mission of this huge under-river sewer is to carry the waste water from the left bank of the Danube to the other side of the river where a large sewage treatment plant is being constructed. In order to carry out its 375 m in length and 2.4 m inside diameter, where several drain pipes and ducts for remote heating and supply of electric power are housed, a system of pressure propulsion has been sed. This system is based on a series of hydraulic presses, which gradually insert into the ground the prefabricated reinforced concrete tubular elements, 3 m in length, which form the sewer. The work on the aforementioned sewer is completed with a pumping well located on the left bank and originated by the difference in level between the connections of the respective sewers on each side of the river — as well as a collection well, situated on the right bank, which links up with the main sewer of the treatment plant. Both wells are built with reinforced concrete.La misión de este gran colector subfluvial es la de conducir las aguas residuales procedentes de la orilla izquierda del Danubio al otro lado del río, en donde se está construyendo una gran planta depuradora. Para la realización de sus 373 m de longitud y 2,40 m de diámetro interior, donde se albergan diversas tuberías de desagüe y conductos para calefacción a distancia y suministro de energía eléctrica, se ha empleado un sistema de propulsión a presión. Dicho sistema se basa en una serie de prensas hidráulicas, que van introduciendo en el terreno los elementos tubulares prefabricados de hormigón armado, de 3 m de longitud, que constituyen el colector. Los trabajos del citado colector se completan con un pozo de bombeo —situado en la orilla izquierda y originada por la diferencia de nivel existente entre las acometidas de los respectivos colectores de ambos lados del río— y otro de recogida, emplazado en la orilla derecha, que enlaza con el colector principal de la

    The present study was carried out on a sample of 125 right-handed boys who are described as follows: 50 boys with dyslexia, 50 controls of a similar age, and 25 controls according to reading level. Using an objective procedure based on regression, we selected three subgroups from among the poor readers: children with difficulties in the lexical pathway (surface dyslexics), children with difficulties in the sublexical pathway (phonological dyslexics), and children with problems in both pathways (mixed dyslexics). When the performances of these children on a dichotic listening task with CV syllables as stimuli were compared, it was found that although the children with dyslexia obtained lower lateralization indices than did the controls, the differences were only clearly significant when the most severe cases of phonological dyslexia were selected.

    The effectiveness of plant based materials Moringa oleifera (Moringa) seeds and Musa cavendish (banana peel) for removing heavy metals namely lead (Pb), nickel (Ni) and cadmium (Cd) from contaminated groundwater was studied. Tests were carried out with individual and combined biomass at neutral pH condition on synthetic groundwater samples. The optimum biomass doses were determined as 200 mg/L for single biomass and 400 mg/L (in the ratio of 200 mg/L: 200 mg/L) for combined biomasses and used for adsorption isotherm studies with contact time of 30 minutes. Results showed that combined biomasses was able to met the Pb, Ni and Cd WHO standards from higher Pb, Ni and Cd initial concentrations which were up to 40 µg/L, 50 µg/L 9 µg/L, respectively compared to individual biomass of Moringa seed and banana peel. Moringa seeds exhibited the highest removal of Pb (81%) while the combined biomasses was most effective in removing Ni (74%) and Cd (97%) over wider their initial concentration ranges. The experimental data were linearized with Langmuir and Freundlich adsorption isotherm models. Freundlich model described the Pb adsorption better than the Langmuir model for all the tested biomasses. However, the Langmuir model fit better with the experimental data of Ni adsorption by Moringa seeds. Both models showed negligible differences in the coefficient of determination (R2) when applied for Ni and Cd adsorption on banana peel and combined biomasses, suggesting that there were multiple layers on the biomass interacting with the metals. Chemisorption is suggested to be involved in Pb adsorption for all tested biomasses as the value of nF calculated was lower than one. This type of adsorption could explain the phenomenon of different behavior of Pb removal and the higher Pb adsorption capacity (represented by KF values) compared to Ni and Cd. The study demonstrates that Moringa seeds, banana peel and their combination have the potential to be used as a natural alternative

CUORE is a cryogenic detector composed of 988 TeO2 bolometers for a total mass of about 741 kg. The detector is being constructed at the Laboratori Nazionali del Gran Sasso, Italy, where it will start taking data in 2015. If the target background of 0.01 counts/(keV·kg·y will be reached, in five years of data taking CUORE will have an half life sensitivity around 1 × 1026 y at 90% C.L. As a first step towards CUORE a smaller experiment CUORE-0, constructed to test and demonstrate the performances expected for CUORE, has been assembled and is running. The detector is a single tower of 52 CUORE-like bolometers that started taking data in spring 2013. The status and perspectives of CUORE will be discussed, and the first CUORE-0 data will be presented.

    Full Text Available 222Rn has been detected in 28 groundwater samples from the northeast of Gran Canaria (Canary Islands, Spain utilizing a closed loop system consisting of an AlphaGUARD monitor that measures radon activity concentration in the air by means of an ionization chamber, and an AquaKIT set that transfers dissolved radon in the water samples to the air within the circuit. Radon concentration in the water samples studied varies between 0.3 and 76.9 Bq/L. Spanish radiological protection regulations limit the concentration of 222Rn for drinking water to 100 Bq/L, therefore the values obtained for all the analyzed samples are below this threshold. The hydrogeological study reveals a significant correspondence between the radon activity concentration and the material characteristics of the aquifer. For a selected group of samples with high radon concentrations, gross alpha activity has been determined to have values higher than the prescriptive screening level (0.1 Bq/L.

    CV247 (CV), an aqueous mixture of copper (Cu) and manganese (Mn) gluconates, vitamin C and sodium salicylate increased the antitumour effects of cisplatin (CDPP; cis-diamminedichloroplatinum) in vitro. We hypothesized that the antioxidant and cyclooxygenase-2 (COX-2; prostaglandin-endoperoxide synthase 2) inhibitory components of CV can protect the kidneys from CDPP nephrotoxicity in rats. CDPP (6.5 mg/kg, intraperitoneally) slightly elevated serum creatinine (Crea) and blood urea nitrogen (BUN) 12 days after treatment. Kidney histology demonstrated extensive tubular epithelial damage and COX-2 immunoreactivity increased 14 days after treatment. A large amount of platinum (Pt) accumulated in the kidney of CDPP-treated rats. Furthermore, CDPP decreased renal iron (Fe), molybdenum (Mo), zinc (Zn), Cu and Mn concentrations and increased plasma Fe and Cu concentrations. CDPP elevated plasma free radical concentration. Treatment with CV alone for 14 days (twice 3 ml/kg/day orally) did not influence these parameters. Chronic CV administration after CDPP reduced renal histological damage and slightly decreased COX-2 immunoreactivity, while failed to prevent the increase in Crea and BUN levels. Blood free radical concentration was reduced, that is, CV improved redox homeostasis. CV restored plasma Fe and renal Fe, Mo and Zn, while decreased Pt and elevated Cu and Mn concentrations in the kidney. Besides the known synergistic antitumour effects with CDPP, CV partially protected the kidneys from CDPP nephrotoxicity probably through its antioxidant effect.

Como su labor de investigador estuvo ligada al departamento de Nariño cuando permaneció dos meses en la ciudad de Pasto en 1939 con el fin de descubrir la causa de una epidemia que mató a más de 8.000 personas en la zona del Guáitara, en compañía de otros tres médicos que se desplazaron desde Bogotá, mientras se desempeñaba como Jefe del Laboratorio de Salud Pública el Dr. Luis Eduardo Martínez, es justo rendirle un homenaje póstumo que permita, además, trazar en pocas líneas la semblanza de su incomparable trayectoria. La epidemia a la que me referí, de carácter infecciosa, fue el resultado de la acción de una bacteria llamada Bartonella, de ahí el nombre de bartonelosis o enfermedad de Carrión, que se expande a través de un mosquito transmisor y produce la destrucción de los glóbulos rojos de la sangre conllevando a la aparición de una anemia severa y a la ulterior muerte. Su descubrimiento tuvo lugar en Sandoná cuando se logró identificar la bacteria bajo el lente del microscopio; bacteria parecida al parásito del paludismo. Hace 7 años nos visitó nuevamente el Dr. Groot y durante su magistral conferencia detalló los hallazgos de su investigación con gran dominio del tema, cualidad propia de una inteligencia superior, sin olvidar los nombres de cada uno de los médicos de la época.

    Full Text Available Nuestro proyecto de viticultura tropical de calidad se inició en la Loma de Puntalarga, en el Valle del Sol en 1982. Los viñedos están situados a gran altura entre los 2400 y los 2600 metros, en terrenos inclinados, consuelos de buena vocación vitícola, bastante brillo solar, calor diurno, frío nocturno y déficit hídrico; condiciones necesarias para producir uvas de alta calidad para vinificación. El cultivo se viene extendiendo desde los años noventa por diversos lugares. En este proceso el río Chicamocha parece ejercer un efecto similar al de otros ríos del vino. Entre los ríos más representativos del hábitat tradicional de las variedades cultivadas en la región, Riesling blanca y Pinot noir, están respectivamente el Rin en Alemania y el Saona en Francia. La distribución geográfica del desarrollo vitícola sigue la dirección del curso del río Chicamocha y prácticamente recubre a la de en claves poblacionales que influenciaba el centro religioso de Sogamoso, antes de la llegada de los españoles en 1537. Algo similar sucede con la distribución de cepas descendientes de la variedad Mission, probablemente introducida por jesuitas a Firavitoba en el siglo XVII. Parece que estos fenómenos podrían relacionarse en menor o mayor grado con la historia geológica regional, en particular la del río Chicamocha. Su conocimiento puede proporcionar valiosas claves sobre los fundamentos del “terroir” y contribuir a acrecentar el carisma, asentado en la calidad, que ya revela el vino regional.

  10. Graphite whiskers in CV3 meteorites.

    Fries, Marc; Steele, Andrew

    2008-04-04

    Graphite whiskers (GWs), an allotrope of carbon that has been proposed to occur in space, have been discovered in three CV-type carbonaceous chondrites via Raman imaging and electron microscopy. The GWs are associated with high-temperature calcium-aluminum inclusion (CAI) rims and interiors, with the rim of a dark inclusion, and within an inclusion inside an unusual chondrule that bears mineralogy and texture indicative of high-temperature processing. Current understanding of CAI formation places their condensation, and that of associated GWs, relatively close to the Sun and early in the condensation sequence of protoplanetary disk materials. If this is the case, then it is a possibility that GWs are expelled from any young solar system early in its history, thus populating interstellar space with diffuse GWs. Graphite whiskers have been postulated to play a role in the near-infrared (near-IR) dimming of type Ia supernovae, as well as in the thermalization of both the cosmic IR and microwave background and in galactic center dimming between 3 and 9 micrometers. Our observations, along with the further possibility that GWs could be manufactured during supernovae, suggest that GWs may have substantial effects in observational astronomy.

    Under two different kinds of nutrient management systems, a field experiment by taking tissue-cultured plant of Brazilian Cavendish banana (Musa AAA Giant Cavendish 'Brazil') as seedling was conducted to establish a fast and accurately quantitative method to forecast the fruit maturity by determination and comparison of finger length, girth and fresh weight as well as the ratio of peel to pulp of every hand per fruit bunch, and by observation the percentage of inflorescence emergence and harvested plants of every treatment at weekly intervals. The results showed that the finger length of banana increased progressively with time, and the same were true for the finger girth, weight and ratio of pulp to peel in fresh weight. The finger length and weight appeared to be variable among hands, but the finger girth stable, which all were significantly affected by nutrient management system and could not be used to forecast maturity of Brazilian Cavendish banana. The date of harvest was considerably influenced by the nutrient management system as well. However, there was no significant difference of the ratio of pulp to peel at harvest either among the 1" to 3rd hands or among the 4th to 6th hands under both nutrient management systems. Therefore, the ratio value of pulp to peel could be used as a quantitative index to judge the fruit maturity of Brazilian Cavendish banana. When the average ratio value reached either 1.65 for the 1st to 3rd hands or 1.54 for the 4th to 6th hands, the 75% fruit maturity was obtained.%以‘巴西蕉’组培苗为试材,于大田条件下,分别在反梳期、膨大前期、膨大后期、采收期测定2种供肥模式下果穗各梳的农艺性状(指长、指围、指重)和鲜果肉皮比,且自抽蕾后定期观测抽蕾率和收获率,试图探寻一种判断‘巴西蕉’果实成熟度之简便易行的定量方法.结果表明:随着果实生长,‘巴西蕉’指长、指围、指重和鲜果肉皮比不断增大;果梳之间

    Full Text Available Four biallelic and six multiallelic Y-chromosome polymorphisms were investigated in 59 Gran Canarian, 60 North African Berber and 46 Spanish subjects. These new data were merged with equivalent literature information to obtain the parental Y-chrosomomal contribution in Gran Canarians, Colombians, and Venezuelans. The results were then compared, for Gran Canarians and Colombians, to those derived from autosomal and mtDNA. In both groups, the Spanish Y-chromosome contribution was much more marked than that estimated using mtDNA. This analysis showed a usual trend in the Spanish Colonial history, characterized by a demographic collapse of the aboriginal population, but with considerable introgression of genes through native women. In accordance to D. Ribeiro's typology for peoples subjected to Colonialism, the Y-chromosomes of these admixed populations are classified as transplanted, their mtDNA as witness, and their autosome sets as new.

    A multidisciplinary study of the Gran Bajo del Gualicho area (Rio Negro - Argentina) was carried out; the aim was to delineate its geological and geomorphological evolution and to estabilish the genesis of salts filling the depression. Climatic conditions were analized first to individuate their role in the present morphogenetic processes; moreover the main morphological features of present landscape were examined as well as the stratigraphy of the outcropping formations, and of the Gran Bajo del Gualicho Formation in particular. Finally, a possible geomorphological evolution of the studied area was traced. Geophysical analyses allowed to estabilish that the paleosurface shaped on the crystalline basement is strongly uneven and shows evidence of the strong tectonic phases it underwent. The result of isotope analyses confirmed that the salt deposits on the Gran Bajo del Gualicho bottom were produced by fresh water evaporation, while strontium isotope ratio suggested that such waters were responsible for solubilization of more ancient evaporitic deposits.

En este artículo estudiamos el oficio de nevero en Gran Canaria, que había sido olvidado por completo, sus salarios, alimentación y especialidades en el s. XVIII.At the end of XVIIIth century the Canary Cathedral Chapter, settled in Gran Canaria Island capital, built, up in the mountains, two snow wells. Workers collected the snow and filled the wells until it was transported, in summer time, from the top of the island (1.949 meters to the city. Snow pounds were sold in the back of the Cathedral from 1694 to 1866.

    Full Text Available Este ensayo examina el caso de las imágenes producidas sobre la Gran Colombia (1819-1830 en Londres como parte de los esfuerzos por ganar reconocimiento para la nueva república en el exterior. Demuestra cómo los deseos territoriales y políticos de los líderes pro-independentistas (que a su vez no estuvieron de acuerdo en cuanto a qué forma debería tener la república en la práctica fueron además restringidos por los intereses imperiales de la Gran Bretaña. Por lo tanto, la geopolítica y los intereses diplomáticos jugaron un papel primordial a la hora de determinar la manera como se representó la extensión de la Gran Colombia durante este periodo en Londres. El considerar los materiales visuales y geográficos producidos dentro de este complejo contexto transnacional nos ayudará a entender aspectos poco examinados por los estudiosos de la historia de la ciencia y de la cultura visual sobre América a principios del siglo XIX. Al resaltar cuán complejas y provisionales fueron aquellas imágenes, el ensayo esclarece las negociaciones domésticas e internacionales que se dieron en torno a lo que debería significar una República de Colombia. Menos importante fue el codificar la república cartográficamente como un país Independiente, de y para ciudadanos, que el crear un territorio civilizado, unificado políticamente, y rico en recursos minerales de cara a los poderes imperiales internacionales que, durante este periodo, estaban en pleno proceso de reconfiguración de sus ámbitos de influencia y dominio.

    2000-01-01

    The performance of cooling and ventilation (CV) equipment is defined as its availability to the PS, SPS and LEP accelerators. Three teams for the accelerators plus a Utilities team, which receives performance information from the physics and technical control room, carry out the operation of this equipment. Collected performance statistics as well as data from the Computer Aided Maintenance Management system (CAMM) and supervision system provide information on the exact state of the CV equipment. This is used to more effectively schedule preventive maintenance which, by reducing system failures, results in improved equipment performance. This paper will present performance data and discuss the prospects for improving it through the use of an updated version of CAMM and a new supervision system.

    Full Text Available Bee Vang, of Minneapolis, played the Hmong lead Thao Vang Lor in Clint Eastwood's 2008 Gran Torino. He was sixteen when he shot the film and had no acting training. For 27 days on location in urban Detroit he played before a Hollywood crew opposite an icon of the filmindustry doing multiple takes of each scene and camera angle. The shoot was full of unexpected twists and turns some of which he recounts in these interchanges with Hmong media expert Louisa Schein of the Departments of Anthropology and Women's and Gender Studies at Rutgers University. Over several conversations, condensed here, Vang and Schein talk about Gran Torino, about acting and film critique, about immigrants and stereotypes, about masculinity and sexuality, and about Vang's vision for what needs to change to address problems of race and inequality in and beyond media worlds.

  2. Modernidad y posmodernidad en El gran señor de Enrique Rosas Paravicino

    Directory of Open Access Journals (Sweden)

    Miguel Arribasplata Cabanillas

    2015-11-01

    Full Text Available En la novela El Gran Señor de Enrique Rosas Paravicino hay una confluencia de pasado histórico y presente conflictivo, donde el fervor religioso cumple un papel de nucleo integrador. En la sociedad andina ficcionalizada aparece una novedosa galería de tipos sociales, como corresponde a un país, como Perú, en pugna por integrar la modernidad con la tradición cultural. Los Andes se constituyen en el gran escenario de una épica popular, con todo el colorido de sus gentes y el paisaje de su cultura. Todo se mueve en torno a un rasgo que es predominante en la novela: el desplazamiento humano en torno a una devoción en plena Cordillera Oriental: el Cristo de la Nieve Resplandeciente. Aquí el sincretismo religioso da lugar a la presencia de personajes involucrados en el mito, la magia y la tradición oral, a la par que asoman los cambios sociales y políticos impulsados por otros actores embarcados en proyectos mundanos, acordes con ese otro gran mito: el progreso colectivo, en perspectiva al desarrollo nacional.

  3. Genes, geology and biodiversity: faunal and floral diversity on the island of Gran Canaria

    Directory of Open Access Journals (Sweden)

    Emerson, B. C.

    2003-01-01

    Full Text Available High levels of floral and faunal diversity in the Canary Islands have attracted much attention to the archipelago for both evolutionary and ecological study. Among the processes that have influenced the development of this diversity, the volcanic history of each individual island must have played a pivotal role. The central island of Gran Canaria has a long geological history of approximately 15 million years that was interrupted by violent volcanism between 5.5 and 3 million years ago. Volcanic activity is thought to have been so great as to have made all plant and animal life virtually extinct, with survival being limited to some coastal species. The implication from this is that the higher altitude laurel forest and pine woods environments must have been re-established following the dramatic volcanic period. This paper reviews the evidence for this using recent molecular phylogenetic data for a number of plant and animal groups on the island of Gran Canaria, and concludes that there is general support for the hypotheses that the forest environments of Gran Canaria post-date the Roque Nublo eruptive period.

    2007-08-01

    Full Text Available Dossier/Issue: 1 - Raconter le quotidien aujourd'hui - Les trois vies de Lucie de Iegor Gran est un roman à contrainte qui raconte trois Vies d’un couple moyen (la troisième version étant la somme des deux premières. Caractéristiques du retour au récit dans la littérature contemporaine, les Vies de Gran associent le motif du quotidien à la catégorie du romanesque, montrant en quoi le quotidien et le romanesque constituent un couple antithétique mais indissociable. Le quotidien est ici un lieu commun qui a plus à voir avec le langage courant et les catégories littéraires qu’avec une réalité insaisissable. Par là, Gran s’écarte des revendications réalistes propres à de nombreuses explorations du quotidien dans la littérature contemporaine. Dans ce contexte, la contrainte qui gouverne le roman n’est pas une simple prouesse ludique sans intérêt : elle contribue à renforcer l’intrication entre quotidien, langage, récit et procédés littéraires.Based on a formal constraint, Iegor Gran’s Les trois vies de Lucie is a novel which recounts the three Lives of an average married couple (the third version being the sum of the first two. Gran’s Lives are quite typical of the renewed interest in narrative in contemporary literature and they demonstrate how everyday life and novelistic adventures form an antithetical but inseparable pair. According to Gran, everyday life is a commonplace which has more to do with ordinary language and literary categories than with an elusive reality. Gran thus stays away from the realistic claims typical of numerous explorations of everyday life in contemporary literature. The formal constraint which governs the novel is more than just a technical exploit, ludic but deprived of any interest : it reinforces the intricate relationship between everyday life, everyday language, narrative, and literary devices.

    Full Text Available Production Management is the act of designing, operating, and improving the productive systems – a system for getting the work done. Along the process, the synergy in between machineries, facilities and people could empower the sustainable of the production. In fact, for some cases, the implementation of unique system is needed for the production process. The example for this transformation production management is in the case of CV Wiracana, a handmade manufacturing company for folding hand fans from Bali. CV Wiracana's products are very unique, combined from mass production for the speed and an art for the custom made product. At one side, the market forces them to speed up the production and for this purpose, they must set up the new system on their production line. On the other side, the masterpiece also needs to be produced without jeopardizing mass production line schedule. The transformation production system needs to be done no later than 2015 as the urgency to fulfill the customer demand, business growth, compete in the industry and sustainability. The changes are expected to improve the production at least about 20% or doubled from the current production.

    Aldo MARCHETTO

    2010-08-01

    Full Text Available Twelve Alpine lakes located in the Gran Paradiso National Park, in the western Italian Alps, were sampled during the ice free period in 2008 and analysed for the main morphological, chemical and physical variables in relation to the characteristics of their watershed, with the aim to create a reference database for present and future ecological studies and to support conservation politics with scientific data. The results highlighted that weathering process and direct precipitation input are the main factors determining the hydrochemistry of the studied lakes; moreover the morphological characteristics highly affects the physical properties of the lakes starting from stratification process. The acidification status, the atmospheric input of N compounds and the supply of nutrients were considered in detail. The studied lakes seem to be well preserved by acidification risk. Comparing data from Gran Paradiso National Park with data from European mountain regions ranging in N deposition rates, allows to consider long range anthropogenic impact: the detection of relative low Total Nitrogen (TN concentration is not necessarily a synonym of a soft impact of long range pollutants, being the final nitrogen concentration dependent from retention process, closely related to catchment characteristics, besides N deposition rates; moreover the dominance of Inorganic Nitrogen (IN on Organic Nitrogen (ON highlights that the lakes are interested by N deposition and probably by long range transport of pollutants produced in the urbanized area surrounding the massif. However the Gran Paradiso National Park area is by far less affected by atmospheric pollutants than other Alpine regions, as the Central Alps. Total Phosphorus (TP concentration in Gran Paradiso lakes (1-13 μg L-1, mean level = 4 μg L-1 is an index of oligotrophic and ultraoligotrophic conditions and according to Redfield's ratio phosphorus is mainly the phytoplankton growth limiting element

    Accurate knowledge of thermonuclear reaction rates is a key issue in nuclear astrophysics: it is important for understanding the energy generation, neutrino production and the synthesis of the elements in stars and during primordial nucleosynthesis. Cross-section measurements are mainly hampered by the very low counting rate and cosmic background. An underground location is extremely advantageous for such studies, as demonstrated by the LUNA experiment in the Gran Sasso Laboratory (Italy). This paper reports on the results recently obtained by this experiment and on the future perspectives in the field.

    Uranium groundwater anomalies, observed before the L'Aquila earthquake (April 6th, 2009) and before the seismic swarm, which occurred in the second half of 2010, represent a key geochemical signal of a progressive increase of deep fluids fluxes at middle-lower crustal levels associated with the geodynamics of the earthquake. In this paper, temporal variations of uranium groundwater are studied in association with the seismic pattern around Gran Sasso National Laboratory (LNGS-INFN). The normalized seismic energy release and the number of earthquakes are analyzed in detail by means of monthly sliding time windows. They are compared with uranium anomalies to highlight any possible correlation.

    Full Text Available Objetivo: Informar sobre el primer hallazgo de Aedes albopictus en el Gran Área Metropolitana de Costa Rica. Métodos: Formas inmaduras de mosquitos colectadas en la Ciudadela La Carpio, Distrito Uruca, San José, como parte de una barrida epidemiológica fueron diagnosticadas preliminarmente como Ae. albopictus. Dicho material se fijó en alcohol al 70 %, se aclaró en lactofenol y se evaluó taxonómicamente mediante claves dicotómicas especializadas. Resultados: Las formas inmaduras evaluadas procedieron de dos criaderos, un tarro y un balde. Las características de las larvas y pupas permitieron identificarlas taxonómicamente como Ae. albopictus. Este es el primer reporte sobre la presencia de dicho vector en Costa Rica. Discusión: La presencia de Ae. albopictus en la Gran Área Metropolitana ocurre como parte del proceso de expansión que está teniendo dicho vector por el territorio nacional. Su presencia debe ser motivo de estudio para determinar su eventual papel en la transmisión del dengue. Por otro lado la presencia de este vector complica la gestión de la vigilancia entomológica de dengue que ha estado dirigida fundamentalmente a la identificación y control del Aedes aegypti.

    Free-living Amoebae of Acanthamoeba genus include non-pathogenic and pathogenic strains that are currently classified in 18 different genotypes, T1-T18. In this study, a survey was carried out to evaluate the presence of Acanthamoeba strains in soil samples collected between 2012 and 2013 in Gran Canaria Island, Canary Islands, Spain. Samples were inoculated onto non-nutrient agar (NNA) plates and were checked for the presence of Acanthamoeba. Identification of Acanthamoeba strains was based on the morphology of the cyst and trophozoite forms. Subsequently, positive samples were cloned for their molecular characterization at the genotype level by sequencing the DF3 region located in the 18S rDNA gene of Acanthamoeba as previously described. Sequencing results revealed the presence of T2, T5 and T4 genotypes within the studied samples. To the best of our knowledge, this is the first report demonstrating the presence of Acanthamoeba in Gran Canaria Island and the first study at the genotype level in the Canary Islands.

    The pressure-temperature-time trajectory and structural history of high-pressure rocks presently exposed in the Gran Paradiso massif provide constraints on the processes that caused their thermal evolution and exhumation. High-pressure metamorphism of the rocks is found to have culminated at temperatures around 525 °C and pressures of 12 to 14 kbar. After high-pressure metamorphism, the rocks cooled during initial decompression, while undergoing top-to-the-west shear on chlorite-bearing shear bands and larger scale shear zones. Biotite-bearing shear bands and larger shear zones related to top-to-the-east deformation affected the Gran Paradiso massif during reheating to temperatures of around 550 °C at 6 to 7 kbar. Further exhumation occurred at relatively high temperatures. A potentially viable explanation of the observed stage of reheating before final cooling and exhumation is breakoff of a subducting slab in the upper mantle, allowing advective heat transfer to the base of the crust.

    ICARUS T600 liquid argon time projection chamber is the first large mass electronic detector of a new generation able to combine the imaging capabilities of the old bubble chambers with the excellent calorimetric energy measurement. After the three months demonstration run on surface in Pavia during 2001, the T600 cryogenic plant was significantly revised, in terms of reliability and safety, in view of its long-term operation in an underground environment. The T600 detector was activated in Hall B of the INFN Gran Sasso Laboratory during Spring 2010, where it was operated without interruption for about three years, taking data exposed to the CERN to Gran Sasso long baseline neutrino beam and cosmic rays. In this paper the T600 cryogenic plant is described in detail together with the commissioning procedures that lead to the successful operation of the detector shortly after the end of the filling with liquid Argon. Overall plant performance and stability during the long-term underground operation are discusse...

    Full Text Available Transhumance – the summer transfer of livestock to highland pastures – is a traditional practice in the European Alps and is considered an integral part of the mountain ecosystem. Mountain lakes are generally oligotrophic systems and are particularly sensitive to the nutrient input caused by livestock. The aim of the present study was to quantify the impact of livestock grazing on the trophic state of high-altitude lakes in an area where transhumance is a traditional practice (Gran Paradiso National Park, Western Italian Alps, taking into account its dual value of ecosystem component and potential threat to lakes’ trophic status. The impact of flocks and herds grazing was estimated on sensitive parameters related to the trophic state of alpine lakes: water transparency, nutrient content, bacterial load and chlorophyll-a concentration. Transhumance produced a significant increase in the trophic state of lakes with high grazing pressure, but little or no effect was found at soft-impacted lakes. Even though heavy-impacted lakes represent a minority of the studied lakes (three out of twenty, we indicated conservation measures such as fencing, wastewater treatment and livestock exclosure to be tested in Gran Paradiso National Park.

    Full Text Available En el presente texto se reflexiona sobre el verdadero estatus de las indígenas de las isla de Gran Canaria  y sus relaciones con las instancias del poder en la sociedad aborigen de los siglos previos a la conquista europea. Para ello se recurre a los datos emanados de las fuentes etnohistóricas y, en menor medida, a las aportaciones de la investigación arqueológica. Se intenta demostrar la precariedad de los argumentos que abogan por la existencia de una sociedad matriarcal donde las mujeres tendrían un destacado papel. También se sugiere la probabilidad de que los sistemas de que organización familiar y de herencia no fueron  estrictamente iguales en las distintas clases sociales.In the present paper, the true status of indigenous women from Gran Canaria island is questioned. It is also discussed the nature of their relationships with the power institutions of the aboriginal society during the previous centuries to the European conquest. Ethnohistoric documents as well as archaeological research are the miain sources of this study. It is tried to show the weakness of the arguments upholding the existence of a matriarchal society in which women had a prominent role. It is also suggested the probability of that every social class had not strictly similar family organization or heredity laws.

    Full Text Available El centenario de la Gran Vía madrileña se ha convertido en la oportunidad de conocer con mayor detalle la mayoría de los elementos más significativos, desde el punto de vista de la arquitectura, que jalonan esta arteria, producto de la última gran reforma interior acometida en la ciudad de Madrid. En apenas veinte años, se yerguen los últimos ejemplos de la arquitectura ecléctica historicista, para pasar de un salto como pocas veces en nuestra historiografía arquitectónica, a la construcción del posiblemente mejor ejemplo de arquitectura racionalista, el Edificio Capitol, acompañado de algunos destellos de arquitectura moderna que, tras el traumático paréntesis de la Guerra Civil y la primera posguerra, se verán acompañados por elementos singulares de una arquitectura en búsqueda de un camino sin sentido, promovida por el final de una generación de arquitectos. Esta sensación de aceleración y freno se liga a algunos de los nombres más destacados de la arquitectura española de los primeros dos tercios del siglo XX: Palacios, Anasagasti, Gutiérrez Soto, Fernández-Shaw, Muguruza, Feduchi o Eced entre otros. Este artículo pretende analizar el papel jugado por la Gran Vía madrileña en cuanto a escenario de transformación de nuestra arquitectura contemporánea, así como su papel de faro hasta el despegar que se produce con los nuevos arquitectos cuyo talento es reconocido desde finales de los años 50 hasta nuestros días. El nuevo lenguaje arquitectónico surgido en las décadas de los años veinte y treinta, y mostrado como en pocos entornos en la Gran Vía, se liga necesariamente a elementos de transformación social, económica y cultural que se traducen en nuevas necesidades y nuevas tipologías edificatorias, en nuevos usos derivados de demandas y transformaciones que cambian nuestra Historia contemporánea, acompañado de un nuevo lenguaje arquitectónico, que por un breve momento, nos situó a la par de las nuevas

    Full Text Available Herbs are used in traditional medicine. There are so many herbs are spread across the world, it is difficult to memorize it all. This paper describes an android application to recognize herbs by their leaf characteristics (shape, veins, and keypoints. Shape and veins of leaves are recognized by Invariant Moment Method as the feature extraction. City Block Distance used to calculate the distance between the features. Whereas for detection and keypoints extraction using Oriented FAST and Rotated BRIEF on OpenCV library. This keypoints distance calculation using Brute-Force Hamming. Matching is done by calculating the shortest distance between test image and reference image. If the result is less than or equal to threshold then image is match. Experiment result show this application can achieve 79% of success rate by using keypoints. This result is influenced by glossy leaf surface, so there is many reflected light that become noise.

    Armando Valenzuela

    2015-05-01

    Full Text Available El desarrollo de la arquitectura del siglo XX no puede entenderse desasociado de la evolución de las tecnologías de la construcción y los sistemas estructurales. La revolución industrial, sobre todo el segundo período, fue un tiempo de grandes avances tecnológicos y enormes cambios sociales que supusieron la transfor­mación de las ciudades y la creación de nuevos tipos edificatorios que pudiesen dar respuestas a las nuevas necesidades sociales y productivas. Fue también en este período cuando se desarrollaron nuevas técnicas y sistemas que mejoraron los estándares de habitabilidad de los edificios. La invención del hormigón armado a mediados del siglo XIX supuso el mayor avance tecnológico y económico de la arquitectura, generando por primera vez una industria especializada y a gran escala que desarrollaba sistemas de construcción basados, primero en ensayos y posteriormente en profundos estudios científicos. Los inventos de sistemas estructurales basados en el hormigón armado se protegieron celosa­mente mediante patentes que garantizaban a sus creadores importantes ingresos económicos a nivel mundial. En las dos primeras décadas del siglo XX aparecieron las primeras normativas nacionales con el fin de evitar el monopolio de las grandes empresas constructoras, liberando los sistemas estructurales y dando paso a los proyectistas.

    Full Text Available A protocol for the in vitro culture of Cucurbita pepo cv. Caserta was studied, using a cotyledon segment with an attached hypocotyl fragment as an explant. First, to determine the optimal seedling age, explants were collected from 4 to 6-day-old in vitro germinated seedlings and cultured in MS basal medium supplemented with benzylaminopurine (BAP, 4.5 µM, under a 16-h photoperiod at 27ºC. Based on the results obtained, the explants collected from the 4-day-old seedlings were then cultured in MS basal medium supplemented with different concentrations of BAP (0, 1.1, 2.2, 3.3, 4.5, or 5.5 µM and incubated under a 16-h photoperiod at 27ºC. In vitro organogenesis was most efficient with explants collected from 4-day-old seedlings cultured in medium supplemented with 4.5 µM of BAP. After 4 weeks of incubation the development of adventitious buds at the cotyledon/hypocotyl junction could be observed. These buds were transferred to elongation and rooting medium and the developed plants were acclimatized to greenhouse conditions. The morphogenic process was characterized using light and scanning electron microscopy analyses to confirm the organogenesis. The results showed that this alternate explant is efficient for in vitro culture of zucchini squash cv. Caserta. The protocol will be further examined for future use in genetic transformation experiments in this species.O objetivo do trabalho foi estudar um protocolo para o cultivo in vitro de Cucurbita pepo cv.

    Full Text Available Abstract The quality of forage production is a prerequisite to raising livestock. Therefore, income losses in this activity, primarily cattle raising, can result in the impossibility of economic activity. Through the qualitative and quantitative anatomical study of Urochloa hybrida cv. Mulato II and U. brizantha cv. Marandu, we searched for descriptions and compared changes in the individual vegetative body from populations with death syndrome pastures (DPS. Specimens were collected at different physiological stages from farms in northern Mato Grosso. After collection, the individuals were fixed in FAA50 and stored in 70% alcohol. Histological slides were prepared from the middle third of the sections of roots, rhizomes, and leaves, and the proportions and characteristics of tissues were evaluated in healthy, intermediate, and advanced stages of DPS. Changes were compared between cultivars. With the advancement of the syndrome, the following changes were observed: a more marked decrease in the length of roots in U. hybrida; disorganization of the cortical region of the roots and rhizome cultivars; fungal hyphae in roots and aerenchyma formation in U. hybrida; a decrease in sclerenchyma fiber proportions in roots and leaves; sclerification of the epidermis of U. brizantha rhizomes; and an increase in pericyclic fibers in U. hybrida. Furthermore, there was a decrease in the volume of epidermal cells of the abaxial face of the leaves of both cultivars, with a greater reduction in U. hybrida; a gradual decrease in thickness in the midrib of leaves similar to leaf mesophyll; conduction system obstructions; partial or total cell lysis in roots and rhizomes affected by the syndrome. Obstructions in sieve tube element and companion cells, and sometimes obstruction in xylem vessel elements. The evolution of DPS in cultivars was similar, but there were variations, arising probably from the physiological response to stress, such as aerenchyma formation in

  5. Exploring Low Luminosity Quasar Diversity at z ~ 2.5 with the Gran Telescopio Canarias

    CERN Document Server

    Sulentic, J W; Marziani, P

    2013-01-01

    We present preliminary results from a pencil-beam spectroscopic survey of low-luminosity quasars at z ~ 2.2-2.5. Our goal is to compare these sources with low redshift analogues of similar luminosity. High s/n and moderate resolution spectra were obtained for 15 sources using the faint object spectrograph Osiris on the 10m Gran Telescopio Canarias. The new data make possible an almost unprecedented comparison between sources with the same (moderate) luminosity at widely different cosmic epochs. Preliminary analysis of our spectra confirms the presence of a relatively evolved population of quasars radiating at modest Eddington ratios. A notable difference between the low and high z quasars may involve the presence of lower metallicity quasars at high redshift.

En este caso en particular, unas botas de hule son el centro de la atención de un joven de una comunidad rural que dice estar enamorado del dueño de dicho calzado. Él va aprendiendo que un sujeto fetichista requiere de su objeto para disfrutar del placer erótico.

  7. Seasonal variations of the rate of multiple-muons in the Gran Sasso underground laboratory

    2016-01-01

    It is well known that the rate of cosmic ray muons depends on the atmospheric temperature, and that for events with a single muon the peak of the rate is in summer, in underground laboratories in the northern hemisphere. In 2015 the MINOS experiment, in USA, found that, for small distances between the multiple-muons, the rate of multiple-muons peaks in the winter and that the amplitude of the modulation is smaller than in the case of a single muon. I have done a re-analysis of data of the past MACRO experiment. The result is that under Gran Sasso the rate of multiple-muons at small distances peaks in the summer. This difference with MINOS could be explained by differences in the atmospheric temperature due to latitude. This results could be of interest for dark matter experiments looking to dark matter seasonal modulation due to the Earth's motion.

    In March 2004 was accepted in the site of Gran Telescopio Canarias (GTC) in La Palma Island, Spain, the Commissioning Instrument (CI) for the GTC. During the GTC integration phase, the CI will be a diagnostic tool for performance verification. The CI features four operation modes-imaging, pupil imaging, Curvature Wave-front sensing (WFS), and high resolution Shack-Hartmann WFS. This instrument was built by the Instituto de Astronomia UNAM in Mexico City and the Centro de Ingenieria y Desarrollo Industrial (CIDESI) in Queretaro, Qro under a GRANTECAN contract after an international public bid. Some optical components were built by Centro de Investigaciones en Optica (CIO) in Leon Gto and the biggest mechanical parts were manufactured by Vatech in Morelia Mich. In this paper we made a general description of the CI and we relate how this instrument, build under international standards, was entirely made in Mexico.

    The authors carried out three electrical soundings, with continuous polar dipole-dipole array, and three magnetotelluric stations at Gran Sasso (Italia), in the area of Campo Imperatore. Geoelectrical data show the existence of a resistive background with exceptionally high values of resistivity (greater than 25000 {Omega}{center_dot}m) at a depth of about 250 m. The magnetotelluric data were used to constrain the thickness of this resistive layer, below which was found an intermediate conductive structure and a deeper resistive background. The geological interpretation of this result is still open to discussion, but can be excluded that the shallow resistive layer consists of Cretaceous limestones, since their resistivity has been estimated to be about 5000 {Omega}{center_dot}m.

Mediante la caricaturización literaria de las cadenas emblemáticas asociadas al fuero de los Casaquemada y el escudo de armas de los antepasados de los Valverde, Eduardo Barrios pone de relieve la persistencia ideológica, en algunos sectores de la sociedad chilena representada en la novela, de un sistema anacrónico de diferenciación social incompatible con el nuevo ideario democrático impulsado con el advenimiento de la república.This essay analyses the array of satirical resources employed by Eduardo Barrios in his Gran Señor y rajadiablos (GreatLordandHellRaiser to create a humoristic narration undermining the ideological perception that favored the Peninsular last name and lineage as hegemonic signs of aristocratic status. Through a literary caricature-like representation of the emblematic chains related to the Casaquemada court of justice and the Valverde predecessors' coat of arms, Barrios satirizes the persistence of an anachronic ideology of social differentiation held by some sectors of the Chilean society represented in this novel. Such ideology becomes incompatible with the new democratic ideals brought along by the emerging Republic.

    Full Text Available During the 1960's and early 1970's heavy prefabricated construction systems were employed on a large scale to attempt to solve the acute shortage of public housing in Britain. Subsequently a high percentage of these multi-storey blocks experienced severe problems: some because of serious technical faults, whilst others for largely social reasons. The problems worsened and during the 1980's large numbers of these blocks were demolished barely 20 years after their construction. This paper assesses the effects of technological choice in housing, discusses the interrelationship between technology design and social factors, and explores the explanations and implications of these failures.

    Durante los años sesenta y años setenta se implantó un programa a gran escala de conjuntos en altura utilizando sistemas de prefabricación pesada para superar el agudo déficit de vivienda social en Gran Bretaña. Un alto porcentaje de estos conjuntos han resultado problemáticos; algunos por serias fallas técnicas y otros por razones sociales. En los últimos años los problemas han venido creciendo hasta que se ha empezado a demoler miles de estas viviendas, la mayoría de las cuales apenas tienen 20 años de vida. Este artículo evalúa los efectos de decisiones sobre tecnología en vivienda, habla de la interrelación entre tecnología, diseño y factores sociales, y explora las explicaciones e implicaciones de estos problemas.

  15. Phylogeography of the endangered darkling beetle species of Pimelia endemic to Gran Canaria (Canary Islands).

    2003-08-01

    Phylogenetic and geographical nested clade analysis (NCA) methods were applied to mitochondrial DNA sequences of Pimelia darkling beetles (Coleoptera, Tenebrionidae) endemic to Gran Canaria, an island in the Canary archipelago. The three species P. granulicollis, P. estevezi and P. sparsa occur on the island, the latter with three recognized subspecies. Another species, P. fernandezlopezi (endemic to the island of La Gomera) is a close relative of P. granulicollis based on partial Cytochrome Oxidase I mtDNA sequences obtained in a previous study. Some of these beetles are endangered, so phylogeographical structure within species and populations can help to define conservation priorities. A total of about 700 bp of Cytochrome Oxidase II were examined in 18 populations and up to 75 individuals excluding outgroups. Among them, 22 haplotypes were exclusive to P. granulicollis and P. estevezi and 31 were from P. sparsa. Phylogenetic analysis points to the paraphyly of Gran Canarian Pimelia, as the La Gomera P. fernandezlopezi haplotypes are included in them, and reciprocal monophyly of two species groups: one constituted by P. granulicollis, P. estevezi and P. fernandezlopezi (subgenus Aphanaspis), and the other by P. sparsa'sensu lato'. The two species groups show a remarkably high mtDNA divergence. Within P. sparsa, different analyses all reveal a common result, i.e. conflict between current subspecific taxonomic designations and evolutionary units, while P. estevezi and P. fernandezlopezi are very close to P. granulicollis measured at the mtDNA level. Geographical NCA identifies several cases of nonrandom associations between haplotypes and geography that may be caused by allopatric fragmentation of populations with some cases of restriction of gene flow or range expansion. Analyses of molecular variance and geographical NCA allow definition of evolutionary units for conservation purposes in both species-groups and suggest scenarios in which vicariance caused by

    The safety and nutritional properties of CV127 soybeans were evaluated in rat and broiler feeding studies. Some episodic differences were observed between rats fed CV127, Conquista, and the standard diet for the endpoints examined. None of these differences were considered treatment related, adverse, or biologically meaningful. In general, birds fed diets containing CV127, Conquista, or Monsoy 8001 showed no significant differences in growth and performance response variables. Chickens fed diets containing Coodetec 217 had lower body weight and weight gain for all developmental periods compared to CV127, but no significant differences were found in feed conversion for the two diets during any development period. The results of both feeding studies demonstrate that CV127 soybeans are as safe, wholesome, and nutritionally valuable as the other soybean meals tested, including those varieties for which histories of safe use have been established and well documented.

    SiGe alloys are currently used for HBT and MOS as epitaxial layers for base or strained channel, respectively. In the poly phase, SiGe has been studied as a replacement for poly-Si in MOS gates due to its lower thermal budget and gate depletion and also due to the Workfunction Engineering for V {sub t} adjustments. However, for application to CMOS technology as poly-SiGe gates, others constrains emerge such as quality of the oxide interface and etch chemistry. For both applications, the Ge fraction normally lies between 20% and 40%. In this study, authors use a low Ge contents (1%) poly-SiGe thin films aiming for MOS gate electrode. The Ge fraction was determined by RBS analysis. 230 nm thick samples were deposited onto 10 nm thermally oxidized <1 0 0>, p-type Si substrates using silane and germane. Films were deposited in the temperature of 500 deg. C and total pressure of 667 Pa (5 Torr) by vertical LPCVD. The samples were doped using {sup 31}P{sup +} ion implantation from 5 x 10{sup 14} cm{sup -2} up to 2 x 10{sup 16} cm{sup -2} and annealed by RTP (40 s) from 500 deg. C up to 900 deg. C. R {sub s} values were obtained by 4-point probe technique and CV curves were extracted from nMOS capacitors with 200 {mu}m diameter. The same processing steps were used to fabricate similar poly-Si samples and capacitors for comparison. The poly-SiGe samples presented R {sub s} values one order of magnitude lower than poly-Si and CV analysis of nMOS capacitors showed very good characteristics. The 1% Ge in the alloy ensures a low thermal budget for the overall process. Although a relatively high annealing temperature (800 deg. C) must be used to reduce oxide charge and interface traps, the temperature is well below the necessary for poly-Si processing and can allow formation of the shallow junctions needed for next technological nodes.

    2008-01-01

    We present new V-band differential brightness measurements as well as new radial-velocity measurements of the detached, circular, 0.84-day period, double-lined eclipsing binary system CV Boo. These data along with other observations from the literature are combined to derive improved absolute dimensions of the stars for the purpose of testing various aspects of theoretical modeling. Despite complications from intrinsic variability we detect in the system, and despite the rapid rotation of the components, we are able to determine the absolute masses and radii to better than 1.3% and 2%, respectively. We obtain M(A) = 1.032 +/- 0.013 M(Sun) and R(B) = 1.262 +/- 0.023 R(Sun) for the hotter, larger, and more massive primary (star A), and M(B) = 0.968 +/- 0.012 M(Sun) and R(B) = 1.173 +/- 0.023 R(Sun) for the secondary. The estimated effective temperatures are 5760 +/- 150 K and 5670 +/- 150 K. The intrinsic variability with a period about 1% shorter than the orbital period is interpreted as being due to modulatio...

    Our goal was to improve the fundamental parameters of the massive close double-lined eclipsing B2.5V+B2.5V binary CV Velorum.We gathered new high-resolution echelle spectroscopy on 13 almost consecutive nights covering essentially two orbits. We computed a simultaneous solution to all the available high-quality radial-velocity and light data with the latest version of the Wilson-Deviney code. We obtained the following values for the physical parameters: $M_1 = 6.066(74) M_\\odot$, $M_2 = 5.972(70) M_\\odot$, $R_1 = 4.126(24) R_\\odot$, $R_2 = 3.908(27) R_\\odot$, $\\log L_1 = 3.20(5) L_\\odot$, and $\\log L_2 = 3.14(5) L_\\odot$. The quoted errors contain a realistic estimate of systematic uncertainties mainly stemming from the effective temperature estimation. We derived abundances for both components and found them to be compatible with those of B stars in the solar neighbourhood. We discovered low-amplitude periodic line-profile variations with the orbital frequency for both components. Their interpretation requir...

    The cultivar Loureiro of Vitis vinifera is one of the most economically important, recommended in almost the totality of the Região Demarcada dos Vinhos Verdes. In vineyards, the grape productivity of this cultivar is normal while in others it is extremely low. The aim of this work was to study the morphology and germination of Vitis vinifera cv. Loureiro pollen with high and low productivity. The pollen grain was examined under light, transmission and scanning electron microscopy. Typically V. vinifera pollen present three furrows but in the cultivar Loureiro we found tricolporated and acolporated (without furrows or pores) pollen grains. Both pollen types present generative and vegetative cells with the usual aspect and a dense cytoplasm rich in organelles. In the acolporated pollen a continuous exine layer and an irregular intine layer were observed. Differences were found in the starch accumulation, since only in tricolporated pollen abundant plastids filled with numerous starch granules were observed. To determine the causes of the low productivity of this cultivar we tested pollen viability by the fluorochromatic reaction and pollen germinability by in vitro assays. We observed that the acolporated pollen grain is viable, but no germination was recorded.

    Accurate and fast detection of infrared (IR) dim target has very important meaning for infrared precise guidance, early warning, video surveillance, etc. In this paper, some basic principles and the implementing flow charts of a series of algorithms for target detection are described. These algorithms are traditional two-frame difference method, improved three-frame difference method, background estimate and frame difference fusion method, and building background with neighborhood mean method. On the foundation of above works, an infrared target detection software platform which is developed by OpenCV and MFC is introduced. Three kinds of tracking algorithms are integrated in this software. In order to explain the software clearly, the framework and the function are described in this paper. At last, the experiments are performed for some real-life IR images. The whole algorithm implementing processes and results are analyzed, and those algorithms for detection targets are evaluated from the two aspects of subjective and objective. The results prove that the proposed method has satisfying detection effectiveness and robustness. Meanwhile, it has high detection efficiency and can be used for real-time detection.

    1984-08-01

    Several user-oriented programs for the Hewlett-Packard HP-41CV are explained. The first program builds, stores, alters, and ages a list of radionuclides. This program only handles single- and double-decay chains. The second program performs convenient conversions for the six nuclides of concern in plutonium handling. The conversions are between mass, activity, and weight percents of the isotopes. The source can be aged and/or neutron generation rates can be computed. The third program is a timekeeping program that improves the process of manually estimating and tracking personnel exposure during high dose rate tasks by replacing the pencil, paper, and stopwatch method. This program requires a time module. The remaining four programs deal with computations of time-integrated air concentrations at various distances from an airborne release. Building wake effects, source depletion by ground deposition, and sector averaging can all be included in the final printout of the X/Q - Hanford and X/Q - Pasquill programs. The shorter versions of these, H/Q and P/Q, compute centerline or sector-averaged values and include a subroutine to facilitate dose estimation by entering dose factors and quantities released. The horizontal and vertical dispersion parameters in the Pasquill-Gifford programs were modeled with simple, two-parameter functions that agreed very well with the usual textbook graphs. 8 references, 7 appendices.

  11. Future Objectives of Maintenance Management in the CV Group

    1999-01-01

    The ST/CV group has an extensive maintenance contract with a multinational consortium (Gematec-F/I/DE). Annually, the contract costs the group about 6 MCHF. Today the technical monitoring of the performance within the contract has become too irregular and different people's roles have not been sufficiently well defined. It has therefore been decided that all the technical, financial and performance-indicating data should be centrally co-ordinated within the group. The objective is to enable an efficient follow-up of the contract with a view to optimization. Another objective is to migrate to the new, more proficient version of the Computer Aided Maintenance Management (CAMM) software and learn to use it to its full potential. This means using its statistics and analysis features in addition to controlling the maintenance activities, spare-parts store, costs, etc. A further aim is to develop standards for the maintenance and the CAMM. This paper will discuss these objectives and the schedule for their implemen...

    In modern data centres, it is an emerging trend to operate and manage computers as software components or logical resources and not as physical machines. This technique is known as â€ワvirtualisation” and the new computers are referred to as â€ワvirtual machines” (VMs). Multiple VMs can be consolidated on a single hardware platform and managed in ways that are not possible with physical machines. However, this is not yet widely practiced for control system deployment. In TS-CV, a collection of VMs or a â€ワvirtual infrastructure” is installed since 2005 for SCADA systems, PLC program development, and alarm transmission. This makes it possible to consolidate distributed, heterogeneous operating systems and applications on a limited number of standardised high-performance servers in the Central Control Room (CCR). More generally, virtualisation assists in offering continuous computing services for controls and maintaining performance and assuring quality. Implementing our systems in a vi...

    A 5.4-kDa antifungal peptide,with an N-terminal sequence highly homologous to defensins and inhibitory activity against Mycosphaerella arachidicola (IC5o=3 μM),Setospaeria turcica and Bipolaris maydis,was isolated from the seeds of Phaseolus vulgaris cv.brown kidney bean.The peptide was purified by employing a protocol that entailed adsorption on Affi-gel blue gel and Mono S and finally gel filtration on Superdex 75.The antifungal activity of the peptide against M.arachidicola was stable in the pH range 3-12 and in the temperature range 0℃ to 80℃.There was a slight reduction of the antifungal activity at pH 2 and 13,and the activity was indiscernible at pH 0,1,and 14.The activity at 90℃ and 100℃ was slightly diminished.Deposition of Congo red at the hyphal tips of M.arachidicola was induced by the peptide indicating inhibition of hyphal growth.The lack of antiproliferative activity of brown kidney bean antifungal peptide toward tumor cells,in contrast to the presence of such activity of other antifungal peptides,indicates that different domains are responsible for the antifungal and antiproliferative activities.

    A 5.4-kDa antifungal peptide, with an N-terminal sequence highly homologous to defensins and inhibitory activity against Mycosphaerella arachidicola (IC(50)= 3 μM), Setospaeria turcica and Bipolaris maydis, was isolated from the seeds of Phaseolus vulgaris cv. brown kidney bean. The peptide was purified by employing a protocol that entailed adsorption on Affi-gel blue gel and Mono S and finally gel filtration on Superdex 75. The antifungal activity of the peptide against M. arachidicola was stable in the pH range 3-12 and in the temperature range 0°C to 80°C. There was a slight reduction of the antifungal activity at pH 2 and 13, and the activity was indiscernible at pH 0, 1, and 14. The activity at 90°C and 100°C was slightly diminished. Deposition of Congo red at the hyphal tips of M. arachidicola was induced by the peptide indicating inhibition of hyphal growth. The lack of antiproliferative activity of brown kidney bean antifungal peptide toward tumor cells, in contrast to the presence of such activity of other antifungal peptides, indicates that different domains are responsible for the antifungal and antiproliferative activities.

    Full Text Available Diabetes and cancer are a major global public health problem. Plant-derived agents with undesirable side-effects were required. This study aimed to evaluate antidiabetic and anticancer activities of the ethanolic leaf extract of Mangifera indica cv. Okrong and its active phytochemical compound, mangiferin. Antidiabetic activities against yeast α-glucosidase and rat intestinal α-glucosidase were determined using 1 mM of p-nitrophenyl-α-D-glucopyranoside as substrate. Inhibitory activity against porcine pancreatic α-amylase was performed using 1 mM of 2-chloro-4 nitrophenol-α-D-maltotroside-3 as substrate. Nitrophenol product was spectrophotometrically measured at 405 nm. Anticancer activity was evaluated against five human cancer cell lines compared to two human normal cell lines using 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide assay. Mango leaf extract and mangiferin exhibited dose-dependent inhibition against yeast α-glucosidase with the IC 50 of 0.0503 and 0.5813 mg/ml, respectively, against rat α-glucosidase with the IC 50 of 1.4528 and 0.4333 mg/ml, respectively, compared to acarbose with the IC 50 of 11.9285 and 0.4493 mg/ml, respectively. For anticancer activity, mango leaf extract, at ≥200 μg/ml showed cytotoxic potential against all tested cancer cell lines. In conclusion, mango leaf possessed antidiabetic and anticancer potential in vitro.

  18. Fluvial dissection, isostatic uplift, and geomorphological evolution of volcanic islands (Gran Canaria, Canary Islands, Spain)

    Digital analysis of torrential gullies ('barrancos') deeply incised into the volcanic Island of Gran Canaria (Canary Islands) allows us to extract the longitudinal profiles and pre-incision surfaces for individual basins, from which morphometric parameters (length, elevation, area, slope) have been calculated. Other derived parameters, such as ridgeline profiles, maximum incision values, volume removed by fluvial erosion, geophysical relief and isostatic uplift, have also been computed. Based on K/Ar ages for the island, well-constrained incision-uplift rates have been calculated by means of the combination of different methodological approaches commonly used in orogens and large mountain ranges. The geomorphological and morphometric analyses reveal that the island is clearly divided into four environmental quadrants determined by the combination of a couple of key-factors: the age of the volcanic surfaces and the climatic conditions. These factors determine a young sector covered with Plio-Quaternary platform-forming lavas (finished at 1.9-1.5 Ma) evolving under contrasting wet (NE) to dry (SE) climates, and an older sector, conserving the residual surfaces of the Miocene shield building (14.5-8.7 Ma) at the ridgelines, also subjected to wet (NW) and dry (SW) climates. Incision is related to the age zonation of the island. Maximum incisions (< 1200 m) are logically recorded in the older SW sector of the island, but incision rates are directly related to the climatic zonation, with maximum mean values in the wet Northern quadrants (0.18-0.12 mm/yr). The evaluation of the material removed by fluvial erosion for individual basins allows us to assess the consequent theoretical isostatic response in the different sectors of the island. The obtained uplift rates indicate that water availability (by drainage area and elevation) is a relevant controlling factor: the records from the wet Northern sectors show uplift values of between 0.09 and 0.03 mm/yr, whereas in the

  4. The TD6 level lithic industry from Gran Dolina, Atapuerca (Burgos, Spain): production and use.

    Technological analysis of lithic artefacts recovered at the Aurora stratum of Atapuerca-TD6 shows that this Lower Pleistocene assemblage is similar to Mode I Technology (=Oldowan tradition) documented at many African sites. Diachronic comparison of the different levels of Gran Dolina allows us to conclude that this particular form of early European technology lacks the production of big flakes to manufacture large tools such as bifaces and cleavers. Rather, it is characterized by the presence of small artefacts, including flakes, denticulates, notches, and side-scrapers, many of which bear use-wear traces of butchery and woodworking. The dominant production technique is orthogonal, which is also reflected in the core recovered at the slightly older level of TD4. The raw materials also found in the Middle Pleistocene occupations at Atapuerca, though with significant proportion differences, have a local origin and include varieties of flint, quartzite and sandstone as well as limestone and quartz. TD6 small artefacts were made from most of these, although the retouched pieces seem to have been preferentially made of the best quality flint, i.e., Cretaceous flint, pointing to the existence of differential use of lithic material, and therefore, some degree of planned knapping behaviour. Most of the "chaînes opératoires" or reduction sequences took place inside the cave, although some artefacts, elaborated on Cretaceous flint, seem to have been retouched off site, possibly near the supply sources.

    Full Text Available Fossil fish teeth are contained in marine deposits dated at ca 4.8 Ma found on the islands of Gran Canaria and Fuerteventura (Canary Islands, Spain. These islands, situated in the North Atlantic Subtropical Gyre, can be considered a mid-way stopover point between the Caribbean Sea, with the Central American Seaway about to close in this epoch, and the Mediterranean, in the first stage of its post-Messinian Gibraltar Seaway period. Accordingly, there existed extensive pantropical communication, particularly for nektonic animals capable of travelling large distances. In this paper, we present a number of fossil fishes, most of which are identified for the first time on the basis of their teeth: the Chondrichthyes species Carcharocles megalodon, Parotodus benedeni, Cosmopolitodus hastalis, Isurus oxyrinchus, Carcharias cf. acutissima, Carcharhinus cf. leucas, Carcharhinus cf. priscus, Galeocerdo cf. aduncus, and the Osteichthyes species Archosargus cinctus, Labrodon pavimentatum, and Diodon scillae. Coincidences are observed between these ichthyofauna and specimens found in the Azores Islands, the Pacific coast of America and the Mediterranean Sea.

    Psoriasis is a chronic inflammatory disease involving about 2-3% of the Norwegian population. Sun exposure has a positive effect on most psoriasis lesions, but ultraviolet (UV) radiation also causes a direct DNA damage in the skin cells and comprises a carcinogenic potential. UV exposure on the skin causes a local as well as a systemic immune suppressive effect, but the relation between sun exposure and these biological effects is not well known. In March 2006 a study was carried out to investigate possible therapeutic outcome mechanisms in 20 psoriasis patients receiving climate therapy at Gran Canaria. This paper presents estimates of their individual skin UV-doses based on UV measurements and the patients' diaries with information on time spent in the sun. On the first day of exposure the patients received on average 5.1 Standard Erythema Doses (SED: median=4.0 SED, range 2.6-10.3 SED) estimated to the skin. During the 15 days study they received 165.8 SED (range 104.3-210.1 SED). The reduction in PASI score was 72.8% on average, but there was no obvious relation between the improvement and the UV dose. The UV doses were higher than those found from climate therapy studies at other locations. It seems beneficial to use more strict exposure schedules that consider the available UV irradiance, depending on time of the day, time of the year and weather conditions.

    1999-10-01

    The vast plain known as the Gran Chaco is a natural region of more than 1--3 million square kilometers, the second largest natural biome in south America, with only the Amazon region being larger. It extends over parts of Argentina, Bolivia, Paraguay and, marginally, Brazil. The original landscape of the region was mostly a park land with patches of hardwoods intermingled with grasslands. Increasing human encroachment, largely by poor campesinos, with associated overgrazing, excessive timber harvesting, charcoal production and over-exploitation of wildlife, is transforming the region into a dense and unproductive shrub land and is contributing to increasing rural poverty. A management system for the sustainable use of the Chaco has been developed based on a multiple-species ranching system that includes beef, timber, charcoal and wildlife production. An evaluation of the management system finds that it is capable of protecting and enhancing the resource base, while providing higher economic returns in a sustainable manner. However, high initial costs, as well as a divergence between the best interests of campersinos and society, jeopardize the feasibility of the managed system.

    Full Text Available Pintaderas are a special type of wooden stamp from the Canary Islands. They are generally hypothesized to be owner's marks. This implies the existence of a flockowning aristocracy and a servile peasantry. This is strinkingly reminiscent of the sharply drawn class distinctions among the ancient inhabitants of the town of Galdar. These nobles attempted to preserve a pure lineage by practising endogamy. In any case, the most interesting aspect of this study is perhaps the possibility of drawing contrasts between conclusions arribed at through archaeological analysis and through ethnoarchaeological methods.

    Este tipo especial de sellos de madera son conocidos en la isla de Gran Canaria con el nombre «pintadera». De acuerdo con la hipótesis general pertenecían a esquemas o marcas de propietarios e implicarían una aristocracia ganadera y un campesinado diferenciado. Es altamente reminiscente de las distinciones de clase tan agudamente dibujadas entre los antiguos habitantes de la ciudad de Gáldar. Estos nobles trataron de preservar la línea pura por medio de la práctica de la endogamia. En cualquier caso, lo más importante de este estudio es quizá la posibilidad de contrastes entre el análisis arqueológico y el método etnoarqueológico.

    Full Text Available Este artículo aborda el impacto de la Gran Guerra en la ciudad de Rosario, Argentina. Releva sus impactos económicos y los significados que se les asignaron. Analiza las formas en que los actores sociales intentaron hacer frente a los efectos críticos del conflicto mundial: encarecimiento de los productos primarios, desabastecimiento y desocupación. En este campo resultan importantes la producción de ferias francas, la construcción de mercados municipales y el abasto directo de productos primarios por parte del municipio. Ante la dimensión y duración del paro, las autoridades comenzaron a tejer nuevas estrategias para intervenir sobre este fenómeno. Se observa una transición de unas estrategias gubernamentales basadas en la represión y la segregación a otras emparentadas con la asistencia y la ayuda social. Si bien estas nuevas herramientas de intervención no tendieron a perdurar y manifestaron su carácter coyuntural y paliativo, una vez superada la crisis, hacia mediados de los años 1920, organizaron el debate sobre la producción de nuevas políticas municipales y del reformismo local.

    Full Text Available Sustainability has become a focal point of the international agenda. At the heart of its range of distribution in the Gran Chaco Region, the elimination of Triatoma infestans has failed, even in areas subject to intensive professional vector control efforts. Chagas disease control programs traditionally have been composed of two divorced entities: a vector control program in charge of routine field operations (bug detection and insecticide spraying and a disease control program in charge of screening blood donors, diagnosis, etiologic treatment and providing medical care to chronic patients. The challenge of sustainable suppression of bug infestation and Trypanosoma cruzi transmission can be met through integrated disease management, in which vector control is combined with active case detection and treatment to increase impact, cost-effectiveness and public acceptance in resource-limited settings. Multi-stakeholder involvement may add sustainability and resilience to the surveillance system. Chagas vector control and disease management must remain a regional effort within the frame of sustainable development rather than being viewed exclusively as a matter of health pertinent to the health sector. Sustained and continuous coordination between governments, agencies, control programs, academia and the affected communities is critical.

    Gran Dolina is a cavity infilled by at least 25 m of Pleistocene sediments. This sequence contains the TD6 stratigraphic unit, whose records include around 170 hominin bones that have allowed the definition of a new species, Homo antecessor. This fossil accumulation was studied as a single assemblage and interpreted as a succession of several human home bases. We propose a complete stratigraphic context and sedimentological interpretation for TD6, analyzing the relationships between the sedimentary facies, the clasts and archaeo-palaeontological remains. The TD6 unit has been divided into three sub-units and 13 layers. Nine sedimentary facies have been defined. Hominin remains appear related to three different sedimentary facies: debris flow facies, channel facies and floodplain facies. They show three kinds of distribution: first a group of scattered fossils, then a group with layers of fossils in fluvial facies, and third a group with a layer of fossils in mixed fluvial and gravity flow facies. The results of this work suggest that some of these hominin remains accumulated in the cave by geological processes, coming from the adjacent slope above the cave or the cave entry, as the palaeogeography and sedimentary characteristics of these allochthonous facies suggest.

    Growing demand for agricultural commodities is causing the expansion of agricultural frontiers onto native vegetation worldwide. Agribusiness companies linking these frontiers to distant spaces of consumption through global commodity chains increasingly make zero-deforestation pledges. However, production and land conversion are often carried out by less-visible local and regional actors that are mobile and responsive to new agricultural expansion opportunities and legal constraints on land use. With more stringent deforestation regulations in some countries, we ask whether their movements are determined partly by differences in land-use policies, resulting in "deforestation havens." We analyze the determinants of investment decisions by agricultural companies in the Gran Chaco and Chiquitano, a region that has become the new deforestation "hot spot" in South America. We test whether companies seek out less-regulated forest areas for new agricultural investments. Based on interviews with 82 companies totaling 2.5 Mha of properties, we show that, in addition to proximity to current investments and the availability of cheap forestland, lower deforestation regulations attract investments by companies that tend to clear more forest, mostly cattle ranching operations, and that lower enforcement attracts all companies. Avoiding deforestation leakage requires harmonizing deforestation regulations across regions and commodities and promoting sustainable intensification in cattle ranching.

    Spatial variations in sand composition were mapped on a regional scale in a terrestrial sand sea, the Gran Desierto of Sonora, Mexico. Mesoscale mapping on a satellite image base allowed quantitative interpretation of the dynamic development of sand sheets and dunes. The results were used to interpret the Quaternary geologic history of the tectonically active region at the mouth of the Colorado River. Landsat thematic mapper multispectral images were used to predict the abundance of different mineralogies of sand grains in a mixed aeolian terrain. A spectral mixing model separated the effects of vegetation and topographically induced shading and shadow from the effects produced by different mineral and rock types. Compositions determined remotely agreed well with samples from selected areas within the spectral limitations of the thematic mapper. A simple discrimination capability for active versus inactive sand surfaces is demonstrated based upon differences in the percentage of low-albedo accessory grains occurring on dormant aeolian surfaces. A technique for discriminating between low-albedo materials and macroscopic shade is implemented by combining thermal images with the results of the spectral mixing model. The image analysis revealed important compositional variations over large areas that were not readily apparent in the field.

    2008-01-01

    The CERN Neutrino to Gran Sasso (CNGS) experiment uses 400GeV protons extracted from the SPS, which travel along 825 meters of beam line before reaching the CNGS target. This beam line is equipped with 23 BPMs capable of measuring both the horizontal and vertical position of the beam. The final BPM is linked to the target station and due to radiation constraints has been designed to work in air. This contribution will give an overview of the BPMs used in the transfer line. It will also provide a detailed explanation of their logarithmic amplifier based acquisition electronics, which consists of an autotriggered sequencer controlling an integrator, the A/D conversion and the Manchester encoded transmission of the digital data to the surface. At the surface the digital data is acquired using the Digital Acquisition Board (DAB) developed by TRIUMF (Canada) for the LHC BPM system. Results from both laboratory measurements and beam measurements during the 2006 CNGS run will also be presented.

    Full Text Available Despite sea-urchins can play an important role affecting the community structure of subtidal bottoms, factors controlling the dynamics of sea-urchin populations are still poorly understood. We assessed the seasonal variation in recruitment of three sea-urchin species (Diadema africanum, Paracentrotus lividus and Arbacia lixula at Gran Canaria Island (eastern Atlantic via monthly deployment of artificial collectors throughout an entire annual cycle on each of four adjacent habitat patches (seagrasses, sandy patches, ‘urchin-grazed’ barrens and macroalgal-dominated beds within a shallow coastal landscape. Paracentrotus lividus and A. lixula had exclusively one main recruitment peak in late winter-spring. Diadema africanum recruitment was also seasonal, but recruits appeared in late summer-autumn, particularly on ‘urchin-grazed’ barrens with large abundances of adult conspecifics. In conclusion, this study has demonstrated non-overlapping seasonal recruitment patterns of the less abundant species (P. lividus and A. lixula with the most conspicuous species (D. africanum in the study area.

    Full Text Available This work aims to investigate biofuels for diesel engines produced on a lab-scale from the fresh water microalgae Chlorella vulgaris (FWM-CV. The impact of growing conditions on the properties of biodiesel produced from FWM-CV was evaluated. The properties of FWM-CV biodiesel were found to be within the ASTM standards for biodiesel. Due to the limited amount of biodiesel produced on the lab-scale, the biomass of dry cells of FWM-CV was used to yield emulsified water fuel. The preparation of emulsion fuel with and without FWM-CV cells was conducted using ultrasound to overcome the problems of large size microalgae colonies and to form homogenized emulsions. The emulsified water fuels, prepared using ultrasound, were found to be stable and the size of FWM-CV colonies were effectively reduced to pass through the engine nozzle safely. Engine tests at 3670 rpm were conducted using three fuels: cottonseed biodiesel CS-B100, emulsified cottonseed biodiesel water fuel, water and emulsifier (CS-E20 and emulsified water containing FWM-CV cells CS-ME20. The results showed that the brake specific fuel consumption (BSFC was increased by about 41% when the engine was fueled with emulsified water fuels compared to CS-B100. The engine power, exhaust gas temperature, NOx and CO2 were significantly lower than that produced by CS-B100. The CS-ME20 produced higher power than CS-E20 due to the heating value improvement as a result of adding FWM-CV cells to the fuel.

    We report the analysis of the first deep optical observations of three isolated γ-ray pulsars detected by the Fermi Gamma-ray Space Telescope: the radio-loud PSR J0248+6021 and PSR J0631+1036, and the radio-quiet PSR J0633+0632. The latter has also been detected in the X-rays. The pulsars are very similar in their spin-down age (τ ˜ 40-60 kyr), spin-down energy (dot{E} ˜ 10^{35} erg s-1), and dipolar surface magnetic field (B ˜ 3-5 × 1012 G). These pulsars are promising targets for multiwavelength observations, since they have been already detected in γ-rays and in radio or X-rays. None of them has been detected yet in the optical band. We observed the three pulsar fields in 2014 with the Spanish 10.4 m Gran Telescopio Canarias (GTC). We could not find any candidate optical counterpart to the three pulsars close to their most recent radio or Chandra positions down to 3σ limits of g' ˜ 27.3, g' ˜ 27, g' ˜ 27.3 for PSR J0248+6021, J0631+1036, and J0633+0632, respectively. From the inferred optical upper limits and estimated distance and interstellar extinction, we derived limits on the pulsar optical luminosity. We also searched for the X-ray counterpart to PSR J0248+6021 with Chandra but we did not detect the pulsar down to a 3σ flux limit of 5 × 10-14 erg cm-2 s-1 (0.3-10 keV). For all these pulsars, we compared the optical flux upper limits with the extrapolations in the optical domain of the γ-ray spectra and compared their multiwavelength properties with those of other γ-ray pulsars of comparable age.

    Full Text Available El abandono de la convertibilidad trajo aparejado un cambio del régimen macroeconómico que contribuyó a la recuperación de la industria nacional y regional, luego de un periodo de pérdida de participación en el producto como consecuencia de políticas que no la favorecieron. Así, la devaluación de 2002 marca un punto de inflexión en la evolución del sector industrial. En ese escenario de tipo de cambio real elevado, la recuperación de la industria se explicó fundamentalmente por el incremento de la “competitividad precio”. Si bien el cambio en el contexto macroeconómico era una condición para posibilitar una recuperación económica, ésta no es suficiente para hacer sustentable un proceso de crecimiento en el largo plazo. Desde el 2005, el aumento de los precios comenzó a erosionar sostenidamente la competitividad del tipo de cambio real, a través del incremento en los costos industriales. Dado que la industria fue el motor de desarrollo durante un largo lapso y, en los últimos años lideró la recuperación económica en la región, este trabajo busca analizar las características del crecimiento industrial en Rosario y el Aglomerado Gran Rosario (AGR a partir de la devaluación y evaluar la evolución de indicadores que podrían afectar su desempeño futuro.

    There are very few sets of long-term measurements of aerosol concentrations over the North Atlantic Ocean, yet such data is invaluable in quantifying atmospheric dust inputs to this ocean region. We present an 8-year record of total suspended particles (TSP) collected at three stations on Gran Canaria Island, Spain (Taliarte at sea level, Tafira 269 m above sea level (a.s.l.) and Pico de la Gorra 1930 m a.s.l.). Using wet and dry deposition measurements, the mean dust flux was calculated at 42.3 mg m-2 d-1. Air mass back trajectories (HYSPLIT, NOAA) suggested that the Sahara desert is the major source of African dust (dominant during 32-50% of days), while the Sahel desert was the major source only 2-10% of the time (maximum in summer). Elemental composition ratios of African samples indicate that, despite the homogeneity of the dust in collected samples, some signatures of the bedrocks can still be detected. Differences were found for the Sahel, Central Sahara and North of Sahara regions in Ti/Al, Mg/Al and Ca/Al ratios, respectively. Elements often associated with pollution (Pb, Cd, Ni, Zn) appeared to share a common origin, while Cu may have a predominantly local source, as suggested by a decrease in the enrichment factor (EF) of Cu during dust events. The inter-annual variability of dust concentrations is investigated in this work. During winter, African dust concentration measurements at the Pico de la Gorra station were found to correlate with the North Atlantic Oscillation (NAO) index.

    The OPERA neutrino oscillation experiment has been designed to prove the appearance of ντ in a nearly pure νμ beam (CNGS) produced at CERN and detected in the underground Hall C of the Gran Sasso Laboratory, 730 km away from the source. In OPERA, τ leptons resulting from the interaction of ντ are produced in target units called bricks made of nuclear emulsion films interleaved with lead plates. The OPERA target contains 150000 of such bricks, for a total mass of 1.25 kton, arranged into walls interleaved with plastic scintillator strips. The detector is split into two identical supermodules, each supermodule containing a target section followed by a magnetic spectrometer for momentum and charge measurement of penetrating particles. Real time information from the scintillators and the spectrometers provide the identification of the bricks where the neutrino interactions occurred. The candidate bricks are extracted from the walls and, after X-ray marking and an exposure to cosmic rays for alignment, their emulsion films are developed and sent to the emulsion scanning laboratories to perform the accurate scan of the event. In this paper, we review the design and construction of the detector and of its related infrastructures, and report on some technical performances of the various components. The construction of the detector started in 2003 and it was completed in Summer 2008. The experiment is presently in the data taking phase. The whole sequence of operations has proven to be successful, from triggering to brick selection, development, scanning and event analysis.

    Full Text Available The Germanium Detector Array (Gerda is a low background experiment at the Laboratori Nazionali del Gran Sasso (LNGS of the INFN designed to search for the rare neutrinoless double beta decay (0νββ of 76Ge. In its first phase, high purity germanium diodes inherited from the former Heidelberg-Moscow and Igex experiments are operated “bare” and immersed in liquid argon, with an overall background environment of 10−2 cts/(keV·kg·yr, a factor of ten better than its predecessors. Measurements on two-neutrino double beta decay (2νββ giving T1/22ν=(1.88±0.10×1021 yr and recently published background model and pulse shape performances of the detectors are discussed in the paper. A new result on 0νββ has been recently published with a half-life limit on 0νββ decay T1/20ν>2.1×1025 yr (90% C.L.. A second phase of the experiment is scheduled to start during the year 2014, after a major upgrade shutdown. Thanks to the increased detector mass with new designed diodes and to the introduction of liquid argon instrumentation techniques, the experiment aims to reduce further the expected background to about 10−3 cts/(keV·kg·yr and to improve the 0νββ sensitivity to about T1/20ν>1.5×1026 yr (90% C.L..

  17. Deposition of rheomorphic ignimbrite D (Mogán Formation), Gran Canaria, Canary Islands, Spain

    Kobberger, Gustav; Schmincke, Hans-Ulrich

    Rheomorphic ignimbrite D (13.4Ma, Upper Mogán Formation on Gran Canaria), a multiple flow-single cooling unit, is divided into four major structural zones that differ in fabric and finite strain of deformed pyroclasts. Their structural characteristics indicate contrasting deformation mechanisms during rheomorphic flow. The zones are: (a) a basal zone (vitrophyre) with pure uniaxial flattening perpendicular to the foliation; (b) an overlying shear zone characterized by asymmetric fabrics and a significantly higher finite strain, with an ellipsoid geometry similar to stretched oblate bodies; (c) a central zone with a finite strain geometry similar to that of the underlying shear zone but without evidence of a rotational strain component; and (d) a slightly deformed to non-deformed top zone where the almost random orientation of subspherical pyroclasts suggests preservation of original, syn-depositional clast shapes. Rheomorphic flow in D is the result of syn- to post-depositional remobilization of a hot pyroclastic flow as shown by kinematic modeling based on: (a) the overall vertical structural zonation suggested by finite strain and fabric analysis; (b) the relation of shear sense to topography; (c) the interrelationship of the calculated vertical cooling progression at the base of the flow (formation of vitrophyre) and the related vertical changes in strain geometry; (d) the complex lithification history; and (e) the consequent mechanisms of deformational flow. Rheomorphic flow was caused by load pressure due to an increase in the vertical accumulation of pyroclastic material on a slope of generally 6-8°. We suggest that every level of newly deposited pyroclastic flow material of D first passed through a welding process that was dominated by compaction (pure flattening) before rheomorphic deformation started.

  18. Multidimensional spatial characterization of plant invasions in 'El Pinacate y Gran Desierto de Altar' Biosphere Reserve

    Sanchez Flores, Erick

    Invasive species are considered an agent of ecological change with more significant effects than global warming. Exotic plant invasions threaten biodiversity and ecosystem viability worldwide. Their effects in the Sonoran Desert ecosystems are a growing concern among ecologists and land managers. We hypothesized that highly dynamic desert environments are unstable, therefore more vulnerable to invasion by exotic plant species. To test this hypothesis we used a multidimensional approach to assess the spatial distribution of two exotic species: Brassica tournefortii (Saharan mustard) and Schismus arabicus (Arabian grass), in a portion of 'El Pinacate y Gran Desierto de Altar' Biosphere Reserve (PBR) in northwestern Sonora, Mexico. This approach combined genetic algorithms, geographic information systems, field methods, statistical analysis, and remote sensing modeling at multiple spatial and temporal scales to predict and test the current and potential distribution of the invasives over dynamic landscapes. Predicted probability of invasion was influenced strongly by human factors: Road networks were the strongest predictors of presence, revealing the potential importance of humans as vectors of invasiveness. Dynamic landscapes, associated mostly with vegetation losses, were detected spectrally in the eastern portion of the study area, very likely associated with past agricultural and current grazing activity. Combined models of high probability for invasion by B. tournefortii and S. arabicus over dynamic landscapes were tested against confirmed locations of the invasives and land cover types associated with invasion. Results confirmed the hypothesis of the study and suggest that more dynamic landscapes are more prone to invasion by these two exotic plants in the PBR. B. tournefortii was found associated mostly with landscapes occupied by microphyllous desert scrub and grassland, as well as sarcocaulescent desert scrub. S. arabicus was found more abundantly in the

    Sub-population structure and intricate kinship dynamics might introduce biases in molecular anthropology studies and could invalidate the efforts to understand diseases in highly admixed populations. In order to clarify the previously observed distribution pattern and morbidity of Chagas disease in Gran Chaco, Argentina, we studied two populations (Wichí and Criollos) recruited following an innovative bio-cultural model considering their complex cultural interactions. By reconstructing the genetic background and the structure of these two culturally different populations, the pattern of admixture, the correspondence between genealogical and genetic relationships, this integrated perspective had the power to validate data and to link the gap usually relying on a singular discipline. Although Wichí and Criollos share the same area, these sympatric populations are differentiated from the genetic point of view as revealed by Non Recombinant Y Chromosome genotyping resulting in significantly high Fst values and in a lower genetic variability in the Wichí population. Surprisingly, the Amerindian and the European components emerged with comparable amounts (20%) among Criollos and Wichí respectively. The detailed analysis of mitochondrial DNA showed that the two populations have as much as 87% of private haplotypes. Moreover, from the maternal perspective, despite a common Amerindian origin, an Andean and an Amazonian component emerged in Criollos and in Wichí respectively. Our approach allowed us to highlight that quite frequently there is a discrepancy between self-reported and genetic kinship. Indeed, if self-reported identity and kinship are usually utilized in population genetics as a reliable proxy for genetic identity and parental relationship, in our model populations appear to be the result not only and not simply of the genetic background but also of complex cultural determinants. This integrated approach paves the way to a rigorous reconstruction of

    Full Text Available Abstract Between 1992 and 2001, small mammals were trapped in the Gran Paradiso National Park (NW Italy, using Capture-Mark-Recapture techniques. According to a sample of data collected in August, the following percentages were found for the genus Apodemus: 25.9% of the individuals caught in alder shrubwoods, 20.9% in hardwoods, 12.1% in open habitat-types and 3.1% in coniferous woods. Further trapping, carried out in winter in the villages inside the Park, demonstrated that Apodemus occurrence inside the buildings was quite common. Fiftytwo specimens were sacrificed and identified by protein electrophoresis and/or molecular analyses as A. alpicola (N= 14, A. flavicollis (N= 21 and A. sylvaticus (N= 17. External morphology and biometric parameters were analysed on the above specimens, as were cranial features, and the effectiveness of the determination technique proposed by Reutter et al. on the study area material was verified. This technique enabled us to determine other specimens (mainly from discarded bottles using skull analysis. A. flavicollis (recorded from the lowest altitude of the area, 750 m, up to 2123 m a.s.l. dominated in hardwoods. A. alpicola (recorded from 1580 m to 2423 m is more abundant above 1750 m, in alder shrubwoods and in open habitat-types, characterized by patches of rocky elements, low ligneous and herbaceus vegetation. All the individuals caught inside buildings were A. sylvaticus, but this species (recorded from 750 m to 1960 m was scarcely observed in natural habitats. Strix aluco and Aegolius funereus prey remains, collected in the area during the breeding period of both owls, were examined. Apodemus accounted for 13.7% of prey and 9.4% of biomass eaten by Strix aluco and for 7.2% of prey and 7.3% of biomass consumed by Aegolius funereus. Riassunto

    We are experimentally investigating possible violations of standard quantum mechanics predictions in the Gran Sasso underground laboratory in Italy. We test with high precision the Pauli Exclusion Principle and the collapse of the wave function (collapse models). We present our method of searching for possible small violations of the Pauli Exclusion Principle (PEP) for electrons, through the search for ``anomalous'' X-ray transitions in copper atoms, produced by ``fresh'' electrons (brought inside the copper bar by circulating current) which can have the probability to undergo Pauli-forbidden transition to the 1 s level already occupied by two electrons and we describe the VIP2 (VIolation of PEP) experiment under data taking at the Gran Sasso underground laboratories. In this talk the new VIP2 setup installed in the Gran Sasso underground laboratory will be presented. The goal of VIP2 is to test the PEP for electrons with unprecedented accuracy, down to a limit in the probability that PEP is violated at the level of 10E-31. We show preliminary experimental results and discuss implications of a possible violation. Supported by the Austrian Science Fund (project P25529-N20.

    Gran Dolina is a cave (Sierra de Atapuerca, Spain) infilled by a 25 m thick sedimentary record, divided into 12 lithostratigraphic units that have been separated into 19 sedimentary facies containing Early and Middle Pleistocene hominin remains. In this paper, an automated image analysis method has been used to study the shape of the sedimentary particles. Since particle shape is interpreted as the result of sedimentary transport and sediment source, this study can provide valuable data about the sedimentological mechanism of sequence formation. The shape of the sand fraction in 73 samples from Gran Dolina site and Sierra de Atapuerca was analyzed using the Malvern Morphologi G3, an advanced particle characterization tool. In this first complete test, we used this method to the published sequence of Gran Dolina, defined previously through field work observations and geochemical and textural analysis. The results indicate that this image analysis method allows differentiation of the sedimentary facies, providing objective tools to identify weathered layers and measure the textural maturity of the sediments. Channel facies have the highest values of circularity and convexity, showing the highest textural maturity of particles. On the other hand, terra rossa and debris flow samples show similar values, with the lowest particle maturity.

    Canine cardiopulmonary dirofilariosis caused by Dirofilaria immitis is endemic on the island of Gran Canaria. Epidemiological surveys have shown differences in the prevalence of heartworm disease in the canine population of the island between 1989 and 1998. The aim of the present study was to follow-up the prevalence of D. immitis in both the canine population as a whole and the Canarian Warren Hound population on Gran Canaria between 2000 and 2008. Prevalences observed were always significantly higher in the Canarian Warren Hound population than in the entire canine population. A significant decrease in the prevalence (from 30.19% to 19.36%) in the whole population was observed. In the Canarian Warren Hound the prevalence decreased slightly between 2000 and 2007 (40.42-34.65%), rising in 2008 to values higher than those observed at the beginning of follow-up study (41.6%). These changes are mainly attributed to lack of preventive chemotherapy and the prolonged exposure of the Canarian Warren Hound to mosquito bites. As this breed can act as a natural reservoir in Gran Canaria, regular surveillance is needed to detect changes in the epidemiological picture on this island.

    This paper presents the characterization of the sedimentary environment and other sedimentological features of the Transitional Zone of the Galicia continental margin, in the vicinity of the giant pock -mark structure known as the Gran Burato. The area is characterized by marginal platforms and a horst-graben system controlled by NW-SE oriented normal faults. In this zone, three giant pockmark structures, one of them known as the Gran Burato, were reported as associated to large-scale fluid escapes. The study area is located on the Transitional Zone (TZ) of the Galicia passive continental margin, which extends from Cape Finisterre (43o N) in the North to around 40oN in the South. This margin shows a complex structural configuration, which is reflected in the seabed, owing to tectonic movements from Mesozoic rifting phases and Eocene compression (Pyrennean Orogeny). Sedimentological, geochemical and physical properties analysis and 14C AMS-dating of a 4 m piston core extracted in the vicinity of the Gran Burato complemented by multibeam and TOPAS surveys allowed characterizing of the sedimentary environment in the study area. The interpretation of these data showed that the sedimentary and tectonic evolution of the area controlled by the activity of fluid dynamics.

    The variation regularity of browning degree (BD), polyphenol oxidase (PPO) and peroxidase (POD) of Dajiao banana (Musa paradisiaca ABB cv. Dajiao) was observed and compared with other two banana varieties, Fenjiao and Cavendish. Meanwhile, the role of total and free phenol contents in the browning of Dajiao banana was investigated. BD indicated a progressively increasing trend in the three varieties of banana during postharvest ripening, and Fenjiao and Cavendish browned significantly faster than Dajian after the 13^th day of storage, suggesting that Dajiao was more suitable for deep processing. In addition, Dajiao exhibited low PPO and POD activities and low free phenol content but high total phenol content and consequently browned slowly, demonstrating an association between the BD and PPO or POD activities and a negative correlation between the browning rate and free content of The correlation coefficients between BD and PPO POD activities phenol Dajiao. or were 0.8789 and 0.9240, respectively. Thus, there is a close correlation between the browning potential and PPO or POD activities of Dajiao. The main browning substrates in Dajiao were gallic acid and epicatechin as preliminarily identified using UV-VIS absorption spectroscopy and HPLC.%以粉蕉和香牙蕉为对照,观察大蕉后熟过程中褐变度、多酚氧化酶和过氧化物酶的变化规律,同时考察大蕉总酚和游离酚含量分别在大蕉褐变过程中起的作用。结果表明:三种香蕉在后熟过程中,褐变度均呈逐渐增长趋势,在储藏13d后,粉蕉与香牙蕉的褐变速率明显高于大蕉,说明大蕉更适合于作为深加工的原料。在储藏13d后,大蕉的多酚氧化酶和过氧化物酶比活力均比较低,游离酚含量也比较低,但总酚含量较高,最终导致褐变速率较慢,说明大蕉的褐变度同多酚氧化酶和过氧化物酶有一定的相关性,大蕉的褐变速率与游离酚的含量呈

    2010-05-01

    During Jurassic-Cretaceous times, the area of the central Apennines was part of a large, Bahamian-type carbonate platform-basin system, whereby the area of the Gran Sasso was situated between the carbonate platform of Latium and the Abruzzi in the west and the deep basinal area of Marche-Umbria to the east. This transitional area experienced 1. Early Jurassic rifting of the Adriatic margin, leading to the opening of the Ligurian branch of Tethys; 2. prolonged thermal subsidence of the carbonate-platform slope and base-of-slope in the Jurassic-Cretaceous; 3. decollement along Triassic evaporites, thrusting and folding during the Neogene formation of the arc of Gran Sasso and 4. post-nappe normal faulting persisting to this date. Mapping of the western part of the E-W-trending ridge of the Gran Sasso d'Italia has yielded the following results: 1 - The early Jurassic rifting event led to the segmentation of the platform slope into structural highs (Corno Grande and Acqua San Franco) and basins (Pizzo d'Intermesoli, M. Corvo) as suggested by the pronounced differences in thickness of the early-middle Liassic syn-rift sediments (Corniola Formation). Whereas the Acqua San Franco structural high in the west was buried during the Toarcian, the Corno Grande high in the east persisted throughout Mesozoic times at least into the early Tertiary. The longevity and possible tectonic reactivation of the submarine topography, inherited from early Liassic rifting, persisted way into Jurassic-Middle Miocene as suggested by the pronounced differences in thickness of the Jurassic base-of-slope (Corno Piccolo Formation) and Oligocene to Miocene distal ramp sediments, and sequences punctuated by stratigraphic gaps on the highs. 2 - During the Tertiary orogeny of the Apennines, the inherited Mesozoic structures evolved into N-S trending transfer zones between the individual thrusts and folds over- and underthrusting the more external Laga unit.

    High precision secondary ion mass-spectrometry (SIMS) analyses of kirschsteinite (CaFeSiO4) in the reduced CV3 chondrites Vigarano and Efremovka yield well resolved 53Cr excesses that correlate with 55Mn/52Cr, demonstrating in situ decay of the extinct short-lived radionuclide 53Mn. To ensure proper correction for relative sensitivities between 55Mn+ and 52Cr+ ions, we synthesized kirschsteinite doped with Mn and Cr to measure the relative sensitivity factor. The inferred initial ratio (53Mn/55Mn)0 in chondritic kirschsteinite is (3.71 ± 0.50) × 10-6. When anchored to 53Mn-53Cr relative and U-corrected 207Pb-206Pb absolute ages of the D'Orbigny angrite, this ratio corresponds to kirschsteinite formation 3.2-0.7+08 Ma after CV Ca-, Al-rich inclusions. The kirschsteinite data are consistent within error with the data for aqueously-formed fayalite from the Asuka 881317 CV3 chondrite as reported by Doyle et al. (2015), supporting the idea that Ca-Fe silicates in CV3 chondrites are cogenetic with fayalite (and magnetite) and formed during metasomatic alteration on the CV3 parent body. Concentrically-zoned crystals of kirschsteinite and hedenbergite indicate that they initially formed as near end-member compositions that became more Mg-rich with time, possibly as a result of an increase in temperature.

  18. The definition of the western boundary of the Guarani Aquifer System (Gran Chaco, Argentina): technical or conventional; Definicion del limite occidental del Sistema Acuifero Guarani (Gran Chaco, Argentina): tecnico o convencional

    Unlike the eastern, northern and southern borders of the Guarani aquifer system (GAS), which extends beneath considerable regions of Argentina, Brazil, Paraguay and Uruguay, the western boundary, within the Gran Chaco, has no clear hydrogeologic definition that can be recognized at either the surface or subsurface. For this reason, the precise location of the aquifer in this area is open to many different possibilities, depending upon the factors or interests involved. Thus technical specialists have proposed locations that include or exclude, according to their own criteria, large sections of the Argentine Gran Chaco, the management and use of which, from an administrative point of view, imply diverse economic consequences. The Lomadas de Otumpa, located near the border between the Santiago del Estero and Chaco provinces, are gently sloping hills, rising to a height of no more than 110 m above the wide expanse of surrounding plains comprising the Gran Chaco. They trend NNE and are 200 km long and from 20 to 80 km in width, reflecting the presence of the regional Otumpa alignment. The Lomadas de Otumpa are clearly defined at the surface and thus they allow a geographical boundary to be imposed on the GAS sequences according to: i) their notable structural features at the surface, and ii) the close matching of the thinning and/or absence of the associated sedimentary record underground. Because the definition of the limits of the GAS has an influence on its evaluation, management, use and conservation, both at a technical and administrative level, it is of great importance to ascertain its hydrogeologic boundaries.

    A short period eclipsing binary star CV Boo is tested for the possible existence of additional bodies in the system with a help of the light equation method. We use data on the moments of minima from the literature as well as from our observations during 2014 May--July. A variation of the CV Boo's orbital period is found with a period of $\\approx 75$ d. This variation can be explained by the influence of a third star with a mass of $\\approx 0.4M_{\\odot}$ in an eccentric orbit with $e\\approx 0.9$. A possibility that the orbital period changes on long time scales is discussed. The suggested tertiary companion is near the chaotic zone around the central binary, so CV Boo represents an interesting example to test its dynamical evolution. A list of 14 minima moments of the binary obtained from our observations is presented.

Further, a specifi c research work on large cross sectiontimber is explained. A total of 395 pieces of sawn timber from three species (Pinus sylvestris L., Pinus nigra subs. salzmanii (Dunal Franco and Pinus radiata D. Don with cross section between 150x200 y 200x250 mm, have been visually graded according to UNE 56544 standard obtaining its output and mechanical properties. The percentage of rejected pieces is too high (38 to 45% and therefore, a modifi cation of standard specifications is proposed. The output is highly improved in the proposal of standard (rejected percentage of 11 to 17% whereas the mechanical properties are not modified in practice.A similar procedure was applied to 85 timber pieces from old timber structures of building demolition of Pinus sylvestris L. and Pinus pinaster Ait. The percentage of rejected pieces is 52% in a visual grading according to the application of all grading parameters of the standard UNE 56544:2003. This procedure is not practical for existing structures and therefore, it is proposed the application of grading considering only the parameters of knots size and slope of grain. In that way the output is improved reducing the rejected percentage to 10%.En este artículo se realiza una exposición general del efecto del tamaño en las propiedades mecánicas de la madera y la evolución que han sufrido los procedimientos de ensayo y clasifi caciónpor esta razón.

    A new meteorite find, named Khatyrka, was recovered from eastern Siberia as a result of a search for naturally occurring quasicrystals. The meteorite occurs as clastic grains within postglacial clay-rich layers along the banks of a small stream in the Koryak Mountains, Chukotka Autonomous Okrug of far eastern Russia. Some of the grains are clearly chondritic and contain Type IA porphyritic olivine chondrules enclosed in matrices that have the characteristic platy olivine texture, matrix olivine composition, and mineralogy (olivine, pentlandite, nickel-rich iron-nickel metal, nepheline, and calcic pyroxene [diopside-hedenbergite solid solution]) of oxidized-subgroup CV3 chondrites. A few grains are fine-grained spinel-rich calcium-aluminum-rich inclusions with mineral oxygen isotopic compositions again typical of such objects in CV3 chondrites. The chondritic and CAI grains contain small fragments of metallic copper-aluminum-iron alloys that include the quasicrystalline phase icosahedrite. One grain is an achondritic intergrowth of Cu-Al metal alloys and forsteritic olivine ± diopsidic pyroxene, both of which have meteoritic (CV3-like) oxygen isotopic compositions. Finally, some grains consist almost entirely of metallic alloys of aluminum + copper ± iron. The Cu-Al-Fe metal alloys and the alloy-bearing achondrite clast are interpreted to be an accretionary component of what otherwise is a fairly normal CV3 (oxidized) chondrite. This association of CV3 chondritic grains with metallic copper-aluminum alloys makes Khatyrka a unique meteorite, perhaps best described as a complex CV3 (ox) breccia.

  7. Groundwater flow in a volcanic-sedimentary coastal aquifer: Telde area, Gran Canaria, Canary Islands, Spain

    Science.gov (United States)

    Cabrera, M. C.; Custodio, E.

    Groundwater conditions in a 75- km2 coastal area around the town of Telde in eastern Gran Canaria island have been studied. Pliocene to Recent volcanic materials are found, with an intercalated detrital formation (LPDF), which is a characteristic of the area. Groundwater development has become intensive since the 1950s, mostly for intensive agricultural irrigation and municipal water supply. The LPDF is one order of magnitude more transmissive and permeable than the underlying Phonolitic Formation when median values are compared (150 and 15 m2 day-1 5 and 0.5 m day-1, respectively). These two formations are highly heterogeneous and the ranges of expected well productivities partly overlap. The overlying recent basalts constituted a good aquifer several decades ago but now are mostly drained, except in the southern areas. Average values of drainable porosity (specific yield) seem to be about 0.03 to 0.04, or higher. Groundwater development has produced a conspicuous strip where the watertable has been drawn down as much as 40 m in 20 years, although the inland watertable elevation is much less affected. Groundwater reserve depletion contributes only about 5% of ed water, and more than 60% of this is transmitted from inland areas. Groundwater discharge into the sea may still be significant, perhaps 30% of total inflow to the area is discharged to the sea although this value is very uncertain. Les conditions de gisement de l'eau souterraine d'une région de 75 km2 de la côte Est de l'île de la Grande Canarie (archipel des Canaries), dans le secteur de Telde, ont été étudiées, en utilisant seulement les données fournies par les puits d'exploitation existants. Les matériaux volcaniques, d'âge Pliocène à sub-actuel, sont séparés par une formation détritique (FDLP), qui constitue la principale singularité de cette région. L'exploitation de l'eau souterraine est devenue intensive à partir de 1950, principalement pour des besoins d'irrigation (agriculture

    This study develops a procedure that is related to Generalized Likelihood Uncertainty Estimation (GLUE), called the CV-GLUE procedure, for assessing the predictive uncertainty that is associated with different model structures with varying degrees of complexity. The proposed procedure comprises model calibration, validation, and predictive uncertainty estimation in terms of a characteristic coefficient of variation (characteristic CV). The procedure first performed two-stage Monte-Carlo simulations to ensure predictive accuracy by obtaining behavior parameter sets, and then the estimation of CV-values of the model outcomes, which represent the predictive uncertainties for a model structure of interest with its associated behavior parameter sets. Three commonly used wetland models (the first-order K-C model, the plug flow with dispersion model, and the Wetland Water Quality Model; WWQM) were compared based on data that were collected from a free water surface constructed wetland with paddy cultivation in Taipei, Taiwan. The results show that the first-order K-C model, which is simpler than the other two models, has greater predictive uncertainty. This finding shows that predictive uncertainty does not necessarily increase with the complexity of the model structure because in this case, the more simplistic representation (first-order K-C model) of reality results in a higher uncertainty in the prediction made by the model. The CV-GLUE procedure is suggested to be a useful tool not only for designing constructed wetlands but also for other aspects of environmental management.

    Using the complete GAMA-I survey covering ~142 sq. deg. to r=19.4, of which ~47 sq. deg. is to r=19.8, we create the GAMA-I galaxy group catalogue (G3Cv1), generated using a friends-of-friends (FoF) based grouping algorithm. Our algorithm has been tested extensively on one family of mock GAMA lightcones, constructed from Lambda-CDM N-body simulations populated with semi-analytic galaxies. Recovered group properties are robust to the effects of interlopers and are median unbiased in the most important respects. G3Cv1 contains 14,388 galaxy groups (with multiplicity >= 2$), including 44,186 galaxies out of a possible 110,192 galaxies, implying ~40% of all galaxies are assigned to a group. The similarities of the mock group catalogues and G3Cv1 are multiple: global characteristics are in general well recovered. However, we do find a noticeable deficit in the number of high multiplicity groups in GAMA compared to the mocks. Additionally, despite exceptionally good local spatial completeness, G3Cv1 contains signif...

    A method combining cyclic voltammetry (CV) with x-ray absorption fine structure (XAFS) spectroscopy, viz. CV-XAFS, has been developed to enable in situ real-time investigation of atomic and electronic structures related to electrochemical reactions. We use this method to study the reaction of a Pt/C cathode catalyst in the oxygen reduction reaction (ORR) in an alkaline electrolyte, using x-ray energies near the Pt LIII edge for XAFS measurements. It was found that the current induced by the ORR was first observed at approximately 0.08 V versus Hg/HgO, although the Pt valence, which is reflected in the oxidation states, remained almost unchanged. The electronic structure of the catalytic surface in the ORR was observed to be different in the negative and positive scan directions of CV measurements. Hydrogen adsorption is also discussed on the basis of the observation of this spectral change. We have demonstrated that CV-XAFS provides dynamical structural and electronic information related to electrochemical reactions and can be used for in situ real-time measurements of a catalyst.

    Intensive exploitation and continuous consumption of groundwater reserves (groundwater mining) have been real facts for decades in arid and semiarid areas. A summary of experience in the hydrogeological, economic, social and ethical consequences of groundwater intensive and mining exploitation in Gran Canaria and Tenerife Islands, in the Canarian Archipelago, is presented. Groundwater abstraction is less than recharge, but a significant outflow of groundwater to the sea cannot be avoided, especially in Tenerife, due to its younger volcanic coastal formations. Consequently, the intensive aquifer groundwater development by means of wells and water galleries (tunnels) has produced a groundwater reserve depletion of about 2km(3). Should current groundwater abstraction cease, the recovery time to close-to-natural conditions is from decades to one century, except in the mid and high elevations of Tenerife, where this recovery is not possible as aquifer formations will remain permanently drained by the numerous long water galleries. The socio-economic circumstances are complex due to a long standing history of water resources exploitation, successive social changes on each island, and well-established groundwater water trading, with complex relationships that affect water governance and the resulting ethical concerns. Gran Canaria and Tenerife are in an advanced groundwater exploitation stage and have a large water demand. They are good examples that allow drawing guidelines to evaluate groundwater development on other small high islands. After presenting the hydrogeological background, the socio-economic results are discussed to derive general knowledge to guide on water governance.

  14. Isolation and characterization of CvIV4: a pain inducing α-scorpion toxin.

    Ashlee H Rowe

    Full Text Available BACKGROUND: Among scorpion species, the Buthidae produce the most deadly and painful venoms. However, little is known regarding the venom components that cause pain and their mechanism of action. Using a paw-licking assay (Mus musculus, this study compared the pain-inducing capabilities of venoms from two species of New World scorpion (Centruroides vittatus, C. exilicauda belonging to the neurotoxin-producing family Buthidae with one species of non-neurotoxin producing scorpion (Vaejovis spinigerus in the family Vaejovidae. A pain-inducing α-toxin (CvIV4 was isolated from the venom of C. vittatus and tested on five Na(+ channel isoforms. PRINCIPAL FINDINGS: C. vittatus and C. exilicauda venoms produced significantly more paw licking in Mus than V. spinigerus venom. CvIV4 produced paw licking in Mus equivalent to the effects of whole venom. CvIV4 slowed the fast inactivation of Na(v1.7, a Na(+ channel expressed in peripheral pain-pathway neurons (nociceptors, but did not affect the Na(v1.8-based sodium currents of these neurons. CvIV4 also slowed the fast inactivation of Na(v1.2, Na(v1.3 and Na(v1.4. The effects of CvIV4 are similar to Old World α-toxins that target Na(v1.7 (AahII, BmK MI, LqhIII, OD1, however the primary structure of CvIV4 is not similar to these toxins. Mutant Na(v1.7 channels (D1586A and E1589Q, DIV S3-S4 linker reduced but did not abolish the effects of CvIV4. CONCLUSIONS: This study: 1 agrees with anecdotal evidence suggesting that buthid venom is significantly more painful than non-neurotoxic venom; 2 demonstrates that New World buthids inflict painful stings via toxins that modulate Na(+ channels expressed in nociceptors; 3 reveals that Old and New World buthids employ similar mechanisms to produce pain. Old and New World α-toxins that target Na(v1.7 have diverged in sequence, but the activity of these toxins is similar. Pain-inducing toxins may have evolved in a common ancestor. Alternatively, these toxins may be the

    1993-05-01

    The daily level of physical activity was estimated using the heart rate monitor, PE3000 (Polar Electro, Finland). The level was expressed with the coefficient of variation (CV) of heart rates recorded from waking time to dinner time. In the course of a day of intense physical activity, CV was confirmed to rise significantly. Then the CV was estimated and compared among 3 age classes, young (10-18 years), middle-aged (30-47 years), and elderly (62-76 years). The CVs of young people were significantly higher than those of middle-aged (P < 0.001) and elderly (P < 0.01), regardless of sex. However there was no significant sex difference in all age classes. These results suggest that the CV is an accurate index of daily physical activity. Thus clinicians can use the CV of heart rates to estimate the level of physical activity of individuals which closely relates to QOL.

    In the rosaceous subtribe Pyrinae (formerly subfamily Maloideae), pathogen attack leads to formation of biphenyls and dibenzofurans. Accumulation of these phytoalexins was studied in greenhouse-grown grafted shoots of Malus domestica cv. 'Holsteiner Cox' and Pyrus communis cv. 'Conference' after inoculation with the fire blight bacterium, Erwinia amylovora. No phytoalexins were found in leaves. However, both classes of defence compounds were detected in the transition zone of stems. The flanking stem segments above and below this zone, which were necrotic and healthy, respectively, were devoid of detectable phytoalexins. The transition zone of apple stems contained the biphenyls 3-hydroxy-5-methoxyaucuparin, aucuparin, noraucuparin and 2'-hydroxyaucuparin and the dibenzofurans eriobofuran and noreriobofuran. In pear, aucuparin, 2'-hydroxyaucuparin, noreriobofuran and in addition 3,4,5-trimethoxybiphenyl were detected. The total phytoalexin content in the transition zone of pear was 25 times lower than that in apple. Leaves and stems of mock-inoculated apple and pear shoots lacked phytoalexins. A number of biphenyls and dibenzofurans were tested for their in vitro antibacterial activity against some Erwinia amylovora strains. The most efficient compound was 3,5-dihydroxybiphenyl (MIC=115 μg/ml), the immediate product of biphenyl synthase which initiates phytoalexin biosynthesis.

    Effect of the addition of avocado (Persea americana cv. Hass) or olive (Olea europaea cv. Arbequina) hydroalcoholic leaf extracts (AHE and OHE, respectively) on thermal stability of canola oil (CO) and high oleic sunflower oil (HOSO) during French potatoes frying at 180°C was studied. The extracts were characterized by the total phenolic content, phenol chromatographic profiles and antioxidant activity. B-type trimer procyanidins were the major phenolic compounds identified in AHE. OHE showed higher phenol content, antioxidant activity regarding AHE. CO+OHE and HOSO+OHE decreased the formation of polar compounds and showed an anti-polymeric effect with respect to oils without extracts, whereas AHE extract showed a prooxidant effect on HOSO. Therefore, OHE showed an antioxidant effect on HOSO and CO under the studied conditions. In addition, all systems (CO+AHE, HOSO+AHE, CO+OHE and HOSO+OHE) increased the retention of tocopherols. These results demonstrate the potential utility of OHE as natural antioxidant for oils.

    The peels of Citrus aurantium L. and Citrus sinensis Osbeck cultivars from the Dubrovnik region (south Croatia) were extracted by supercritical CO2 at 40 degrees C and 10 MPa at 1.76 kg/h to obtain enriched extracts in comparison with simple pressing of the peels. The extracts were analyzed in detail by gas chromatography and mass spectrometry (GC-FID/MS). Relevant similarities among the peel oil compositions of C. aurantium and C. sinensis cultivars were found with limonene predominance (up to 54.3%). The principal oxygenated monoterpenes were linalool (3.0%-5.9%), α-terpineol (0.7%-2.4%), linalyl acetate (0.0%-5.0%), geranyl acetate (0.0%-0.4%), (Z)-citral (0.0%-1.8%) and (E)-citral (0.0%-1.9%). Several sesquiterpenes were found with minor percentages. Coumarin derivatives were identified in all the samples among the relevant compounds. Isogeijerin dominated in the peels of C. sinensis cv. Tarocco (15.3%) and C. aurantium (11.2%). Scoparone ranged from 0.1% to 0.5% in all the samples. Bergapten (up to 1.4%), osthole (up to 1.1%) and 7-methoxy-8-(2-formylpropyl)coumarin (up to 1.1%) were found mostly in C. sinensis cv. Doppio Sanguigno. It was possible to indicate a few other differences among the extracts such as higher percentage of linalool, linalyl and geranyl acetates, as well as the abundance of sabinene and isogeijerin in C. aurantium or the occurrence of β-sinensal in C. sinensis cultivars.

    CIRCE is a near-infrared (1-2.5 micron) imager (including low-resolution spectroscopy and polarimetery) in operation as a visitor instrument on the Gran Telescopio Canarias 10.-4m tele scope. It was built largely by graduate students and postdocs, with help from the UF Astronomy engineering group, and is funded by the University of Florida and the U.S. National Science Foundation. CIRCE is helping to fill the gap in time between GTC first light and the arrival of EMIR, and will also provide the following scientific capabilities to compliment EMIR after its arrival: high-resolution imaging, narrowband imaging, high-time-resolution photometry, polarimetry, and low-resolution spectroscopy. There are already scientific results from CIRCE, some of which we will review. Additionally, we will go over the observing modes of CIRCE, including the two additional modes that were added during a service and upgrading run in March 2016.

    Recently it was shown, studying data acquired with in-situ measurements on the Gran Sasso mountain (Italy), for about ten years, by means of a high sensitivity transducer coupled to the free-end section of a stainless steel rod fixed by cement in a rock-drill hole 10 m high, about 2500 m above sea level, that Acoustic Emission (AE) can be affected by more than 90% False Acoustic Emission (FAE) of an electromagnetic origin. A very simple method to solve the problem of the discrimination between AE events due to elastic waves, from FAE signals, due to electromagnetic noise, both coming from the same ``reception-point,'' is presented. The reliability of the obtained separation is confirmed also by the reported amplitude and time distribution of AE events, typical of fracture dynamics and those of FAE events, similar to those of noise.

    In this letter, a real-time C-V (Characteristic-Vector) clustering algorithm is put forth to treat with vast action data which are dynamically collected from web site. The algorithm cites the concept of C-V to denote characteristic, synchronously it adopts two-value [0,1]input and self-definition vigilance parameter to design clustering-architecture. Vector Degree of Matching (VDM) plays a key role in the clustering algorithm, which determines the magnitude of typical characteristic. Making use of stability analysis, the classifications are confirmed to have reliably hierarchical structure when vigilance parameter shifts from 0.1 to 0.99. This non-linear relation between vigilance parameter and classification upper limit helps mining out representative classifications from net-users according to the actual web resource, then administering system can map them to web resource space to implement the intelligent configuration effectually and rapidly.

    Platelet adhesion is a critical step due to its hemostatic role in stopping bleeding after vascular damage. Short dystrophins are the most abundant dmd gene products in nonmuscle tissues, and in association with cytoskeleton proteins contribute to their intrinsic function; while utrophins are dystrophin-homologous related family proteins with structural and functional similarities. We previously demonstrated the presence of Dp71 isoforms, utrophins, and various dystrophin-associated proteins and their participation in cytoskeleton re-organization, filopodia and lamellipodia extension, and in centralizing cytoplasmic granules during the adhesion process of human platelets. To evaluate the morphologic changes and actin-based structures of mdx(3cv) platelets during the adhesion process, we compared the topographic distribution of Dp71d/Dp71Delta110(m) and dystrophin-associated protein in adhered platelets from dystrophic mdx(3cv) mouse. By confocal microscopy, we showed that absence of Dp71 isoforms in platelets from this animal model disrupted dystrophin-associated protein expression and distribution without modifying the platelet morphology displayed during the glass-adhesion process. By immunoprecipitation assays, we proved that up-regulated utrophins were associated with dystrophin-associated proteins to conform the dystrophin-associated protein complex corresponding to utrophins, which might compensate for Dp71 absence in mdx(3cv) platelets.

This study found that the above constituents killed H. nana or reduced their spontaneous movements (oscillation/peristalsis. However, the above constituents at various concentrations demonstrated no larvicidal effect or ability to halt spontaneous parasite movement for 72 h against A. simplex, respectively. In addition, according to an assay of cestocidal activity against H. nana and nematocidal activity against A. simplex, we found that the above compounds showed greater lethal efficacy on H. nana than against A. simplex. Further investigation showed that these above constituents have effects against peroxyl radicals under cestocidal effect. Together, these findings suggest that these constituents of Nelumbo nucifera Gaertn. cv. Rosa-plena might be used as anthelmintic agents against H. nana.

    We present the results of a search for extremely metal-poor (EMP), carbon-enhanced metal-poor (CEMP), and cataclysmic variable (CV) stars using a new exploration tool based on linked scatter plots (LSPs). Our approach is especially designed to work with very large spectrum data sets such as the SDSS, LAMOST, RAVE, and Gaia data sets, and it can be applied to stellar, galaxy, and quasar spectra. As a demonstration, we conduct our search using the SDSS DR10 data set. We first created a 3326-dimensional phase space containing nearly 2 billion measures of the strengths of over 1600 spectral features in 569,738 SDSS stars. These measures capture essentially all the stellar atomic and molecular species visible at the resolution of SDSS spectra. We show how LSPs can be used to quickly isolate and examine interesting portions of this phase space. To illustrate, we use LSPs coupled with cuts in selected portions of phase space to extract EMP stars, CEMP stars, and CV stars. We present identifications for 59 previously unrecognized candidate EMP stars and 11 previously unrecognized candidate CEMP stars. We also call attention to 2 candidate He ii emission CV stars found by the LSP approach that have not yet been discussed in the literature.

    In this paper we present an approach to teaching image processing and pattern recognition with the use of the OpenCV library. Image processing, pattern recognition and computer vision are important branches of science and apply to tasks ranging from critical, involving medical diagnostics, to everyday tasks including art and entertainment purposes. It is therefore crucial to provide students of image processing and pattern recognition with the most up-to-date solutions available. In the Institute of Electronics at the Technical University of Lodz we facilitate the teaching process in this subject with the OpenCV library, which is an open-source set of classes, functions and procedures that can be used in programming efficient and innovative algorithms for various purposes. The topics of student projects completed with the help of the OpenCV library range from automatic correction of image quality parameters or creation of panoramic images from video to pedestrian tracking in surveillance camera video sequences or head-movement-based mouse cursor control for the motorically impaired.

    Full Text Available Sour cherry cv. Marasca is Dalmatian cultivar from XVI century. Cultivation is limited on the north and central part of Dalmatia and on the part of the islands, where it achieves the best quality of fruit, high content of dry matter and sugar respectively, agreeable aroma and intense color. Sour cherry cv. Marasca is source of biologically active ingredients, organic and inorganic compounds, dietary fibers, aromatic compounds and high content of phenolic compounds, particularly anthocyanins and hormone melatonin. Many epidemiological studies showed that phenolic compounds have antioxidant and anti-inflammatory properties, and they have beneficial effect on human health. Marasca is rich with mentioned compounds. Physicochemical composition (total and soluble dry matter, pH value, total acidity during ripening of cv. Marasca ecotype Recta (Cerasus marasca recta grown in Zadar and Split area were determined. Total and soluble dry matter increased and pH value and total acidity showed little change during ripening. The content of phenolic compounds increased during ripening as well as content of anthocyanins, while antioxidant activity decreased with ripening. That indicates there was no correlation between antioxidant activity and content of total phenolic compounds.

    Full Text Available Chili pepper is widely used and cultivated by Indonesian people. There are three species of chili pepper, i.e.: Capsicum annuum L., Capsicum frutescens L., and Capsicum violaceum HBK. Capsicum frutescens L. has a higher economic value due to its pungency and carotenoid content. C. frutescens has several cultivars, one of those is Capsicum frutescens cv. Cakra Hijau. This cultivar is resistant against pest and disease and has very high pungency. This special character of chili pepper is born by its secondary metabolic, Capsaicin. Moreover, capsaicin also serves as defense mechanism, antiarthritis, analgesic, and anticancer. This study aimed to isolate Acyltransferase (AT3 gene which encoding Capsaicin Synthase (CS enzyme.

    The aim of this research is to investigate the heat transfer characteristics of a top heat mode closed-looped oscillating heat pipe with check valves (THMCLOHP/CV). Ethanol is used as a working fluid with filling ratios of 30, 50, and 80% of the total volume of the tube. The THMCLOHP/CV is made of a copper tube with an inside diameter of 2.03 mm. The angle of inclination is 90° from the horizontal axis with 40 turns, two check valves, and an evaporator length of 50, 100, and 150 mm. The operating temperatures are 44 and 55°C. It is found that the thermal resistance decreases significantly as the working temperature is increased. Thus, the evaporator length affects the thermal resistance of the THMCLOHP/CV. The presence of the THMCLOHP/CV is clearly demonstrated to contribute to thermal performance improvement.

    Mangas, J.

    1994-04-01

    Full Text Available The main characteristic of the Pliocene volcanic phase of Gran Canaria. the Cycle 11 or Roque Nublo. is the building of a central stratovolcano. probably reaching more than 2.500 m aboye sea level. Among the most relevant deposits associated to this volcanic edifice are the pyroclastic breccia-type deposits. generally known as «Roque Nublo agglomerates or breccias». These deposits have been gene rally interpreted as pyroclastic flows. However, their emission. transport and depositional mechanisms are hitherto poorly understood. In the present work. the analysis of the paleomagnetic characteristics of the lithic and juvenile fragments and the matrix of these pyroclastic deposits have provide sorne important constraints in their evolution and depositional temperatures. The Roque Nublo ignimbrites seem to have been deposited at temperatures below 300 ºC. In such circumstances. hot water originated by the condensation of interstitial water vapor reacted with the cineritic glass fraction, giving place to zeolite neomineralizations. The relatively fast cooling experimented by the ignimbrites after their emission. as deduced from the paleomagnetic analysis, can be explained by the high proportion of lithics and the intcraction of water as an important factor in the triggering of the eruptions in which the ignimbrites were originated.En Gran Canaria, el Ciclo 11 o Roque Nublo. de edad Pliocena. se caracteriza por la construcción de un estratovolcán que pudo alcanzar al menos 2.500 m de altura.

    Miller, I.; Moore, R.

    1990-01-01

    Root caps of primary, secondary, and seminal roots of Z. mays cv. Kys secrete large amounts of mucilage and are in close contact with the root all along the root apex. These roots are strongly graviresponsive. Secondary and seminal roots of Z. mays cv. Ageotropic are also strongly graviresponsive. Similarly, their caps secrete mucilage and closely appress the root all along the root apex. However, primary roots of Z. mays cv. Ageotropic are non-responsive to gravity. Their caps secrete negligible amounts of mucilage and contact the root only at the extreme apex of the root along the calyptrogen. These roots become graviresponsive when their tips are coated with mucilage or mucilage-like materials. Peripheral cells of root caps of roots of Z. mays cv. Kys contain many dictyosomes associated with vesicles that migrate to and fuse with the plasmalemma. Root-cap cells of secondary and seminal (i.e. graviresponsive) roots of Z. mays cv. Ageotropic are similar to those of primary roots of Z. mays cv. Kys. However, root-cap cells of primary (i.e. non-graviresponsive) roots of Z. mays cv. Ageotropic have distended dictyosomal cisternae filled with an electron-dense, granular material. Large vesicles full of this material populate the cells and apparently do not fuse with the plasmalemma. Taken together, these results suggest that non-graviresponsiveness of primary roots of Z. mays cv. Ageotropic results from the lack of apoplastic continuity between the root and the periphery of the root cap. This is a result of negligible secretion of mucilage by cells along the edge of the root cap which, in turn, appears to be due to the malfunctioning of dictyosomes in these cells.

    Objetivo: Estimar el grado de adhesión al Patrón de Dieta Mediterránea (DM) en gestantes de Gran Canaria antes del embarazo y en el tercer trimestre valorando su relación con el incremento ponderal y la ganancia adecuada de peso durante el mismo. Sujetos y método: Estudio transversal en 170 gestantes de Gran Canaria. Se estimó la adhesión a DM al inicio del embarazo y en el tercer trimestre mediante un cuestionario frecuencia de consumo validado. El índice de masa corporal (IMC) se determinó al inicio y en el tercer trimestre a partir de los datos de peso y talla de la historia clínica. Se calculó la ganancia adecuada de peso según las recomendaciones establecidas por el Instituto de Medicina Estadounidense. Se estableció la asociación entre la adhesión a DM y sus cambios durante el embarazo y el incremento en el IMC (coeficientes de regresión (b) y sus intervalos de confianza al 95% (IC 95%)) y una ganancia de peso adecuada (Odds Ratios (OR) y sus IC 95%). Resultados: Las mujeres con muy alta adhesión a la DM antes del embarazo ganaron menos peso durante el mismo (b: -1,54; IC 95%: 95% -2,53 a -0,56) que las mujeres con muy baja adhesión al patrón. El incremento en un punto en la adhesión a la DM durante el embarazo se asoció con una mayor probabilidad de ganancia de peso adecuada (OR: 1,39; IC 95%: 1,06 a 1,82). Conclusiones: Una alta adhesión a la DM antes del embarazo podría proteger frente a estados de sobrepeso y obesidad durante el mismo. Un mayor incremento en la adhesión a la DM durante la gestación puede aumentar la probabilidad de una ganancia adecuada de peso en el embarazo.

    2010-01-01

    Full Text Available The purpose of this work was to evaluate the effect of wilting and biological additive amendment on chemical composition, fermentation and ruminal degradability of Arachis pintoi cv Belmonte silage. The following treatments were analysed: T1- Arachis pintoi cv Belmonte fresh forage; T2 - Arachis pintoi cv Belmonte fresh forage plus bacterial additive added to the forage prior to the ensilage; T3- Arachis pintoi cv Belmonte wilted by the sun for 4 hours; T4- Arachis pintoi cv Belmonte wilted by the sun plus bacterial additive. The degradability assay was carried out using three rumen-fistuled steers. The biological additive did not affect the chemical composition of silages, in situ degradability of nutrients DM, NDF and CP and of silage fermentation. However, the wilting treatments of the silages increased DM, CP, hemicelulose and decreased N-NH3 concentration, pH value, degradability of soluble fraction “a” from DM NDF and CP. The analysed characteristics suggest that Arachis pintoi cv Belmonte could satisfactorily preserve the forage quality if wilted by the sun during 4 hours, after harvested.

    The characterization of the preferential areas of water infiltration through the vadose zone is of paramount importance to assess the pollution vulnerability of the underlying aquifers. Nevertheless, geometry and the hydraulic conductivity of each geological unit which constitute the unsaturated zone are difficult to study from traditional techniques (samples from trenches) and normally do not go beyond a meter depth from of the surface. On the other hand, boreholes are expensive and provide only local information not always representative of the whole unsaturated zone. For this reason, geophysical techniques and among them the electrical resistivity tomography method can be applicable in volcanic areas, where basaltic rocks, pyroclastic and volcanic ash-fall deposits have a wide range of values. In order to characterize the subsurface geology below the golf course of Bandama (Gran Canaria Island), irrigated with reclaimed wastewater, a detailed electrical resistivity tomography survey has been carried out. This technique has allowed to define the geometry of the existing geological formations by their high electrical resistivity contrast. Subsequently, in representative outcrops the value of resistivity of each of these lithologies has been measured and simultaneously undisturbed samples have been taken measuring the hydraulic conductivity in the laboratory. Finally a statistical correlation between both variables has been established for evaluating the vulnerability to groundwater pollution at different zones of the golf course.

    Full Text Available This building, situated in Egham, Surrey, has been designed and built bearing in mind its true nature, i.e. part of a large university complex in a continual state of development. For this reason it was necessary to think in terms of a structure and modulation which could be easily extended in the future without interrupting Its running too much. The unit consists of a series of blocks in step formation, which fits in perfectly with the landscape. There are offices, laboratories, research areas, etc., and at the end of these, separated from the rest, are two auditoriums or lecture theatres.Este edificio —situado en Eghatn, Surrey— ha sido proyectado y realizado teniendo en cuenta las características propias del tipo, es decir, formando parte de un gran complejo universitario en continuo desarrollo, lo que obliga a pensar en una estructura y una modulación que permitan sucesivas y fáciles ampliaciones, alterando muy poco la marcha del Centro. El conjunto está constituido por una serie de bloques escalonados —que se adaptan perfectamente al terreno— en los que se han ubicado los despachos, laboratorios, zonas de investigación, etcétera, al final de los cuales, y separados de las demás dependencias, están situados los dos auditorios o aulas magnas.

    Full Text Available The African diaspora - caused by the Atlantic slave trade - presented the same historical and spiritual features of the Biblical Exodus, but it was exacerbated by the fact that the colonial system carried out a planned cancellation of the identity of the enslaved subjects. However, the American negro, through escapes and rebellions before the Independence and thereafter through a reworking of his ancestors' oral, musical and religious traditions, from an anonymous “pieza” strived to become a person again. Fernando Ortiz and Alejo Carpentier, two intellectuals of European origin, during the 20th century discovered and gave dignity to the "third root of America" in the Caribbean area. At the end of the century, the slave trade and black slave’s redemption epics have been brought back up literarily by an afro-descending and militant writer. Changó, el gran putas, by the Columbian Manuel Zapata Olivella (1920-2004, is a majestic description of the slave’s apocalypse in the Americas, in its meaning of apotastasy (i.e. the world going back to its primordial perfection, according to the prophecy of the orichas’s king, even if some Andean authors indigenistas, such as Cromwell Jara or Gregorio Martínez, have often visited the Afroamerican cosmogonic world.

    Full Text Available Goat production is an important economic activity for rural communities in the Gran Chaco of Argentina. Goat corrals are important for the survival of peridomestic populations of Triatoma infestans. This study evaluated the impact of modifying the traditional structure of goat corrals on T. infestans populations and goat productivity in the region of Los Llanos (La Rioja. Thirty-nine experimental corrals were constructed and 57 traditional corrals were used as controls. We evaluated the infestations of the control and experimental corrals for five years following construction of the structures. The results showed that the new structures did not prevent the colonization, although it enhanced the detection of infestation at low densities of T. infestans. No significant difference was found in T. infestans population abundance between control and experimental corrals, probably because of the different detectability in the two types of structures, especially among the small nymphs. Although goat productivity average was higher in experimental than in control corrals, no significant difference was found because of high variability. The new structures can be used as a complement to promote the development of rural communities. Acceptability and adoption of the new corrals by the owners was high, as the enclosures offered better protection for the goats, increased growth of kids and facilitated herd handling.

    This paper presents and describes new foot fossils from the species Homo antecessor, found in level TD6 of the site of Gran Dolina (Sierra de Atapuerca, Burgos, Spain). These new fossils consist of an almost complete left talus (ATD6-95) and the proximal three-quarters of a right fourth metatarsal (ATD6-124). The talus ATD6-95 is tentatively assigned to Hominin 10 of the TD6 sample, an adult male specimen with which the second metatarsal ATD6-70+107 (already published) is also tentatively associated. Analysis of these fossils and other postcranial remains has made possible to estimate a stature similar to those of the specimens from the Middle Pleistocene site of Sima de los Huesos (Sierra de Atapuerca, Burgos, Spain). The morphology of the TD6 metatarsals does not differ significantly from that of modern humans, Neanderthals and the specimens from Sima de los Huesos. Talus ATD6-95, however, differs from the rest of the comparative samples in being long and high, having a long and wide trochlea, and displaying a proportionally short neck.

    Various nuclear physics experiments are being carried out in the Istituto Nazionale di Fisica Nucleare Laboratories that have been excavated in the Gran Sasso Massif in the Italian Apennines. These experiments make use of the shield effect provided by a 1400-m-thick rock cover that absorb cosmic rays. It is important to know the real density of the rock cover and the extent of its lateral variation. The density of different sections of the rock cover was determined using the correlation between measured underground gravity data and thickness of the rock cover. Observed gravity was corrected using a 3D model, for the mass deficiency covered by excavation of highway tunnels and the cavities that house the laboratories. The average density of the rock cover was found to be 2720±50 kg m -3. Lateral variations are contained within the uncertainty for most of the sections, except for two sections where densities are lowered by as much as 11% because of the presence of a shallow layer formed by loose Quaternary sediments.

    Full Text Available Objective: To evaluate the impact of the Mediterranean diet (MD on weight gain and obesity in pregnant women in Gran Canaria. Methods: Cross sectional study in 170 pregnant women We measured the adherence to the MD before and during pregnancy by a food frequency questionnaire. Body mass index (BMI was determined in the first prenatal visit. Appropriate weight gain was calculated according to the recommendations set by the American Institute of Medicine. We established the association between the degree of compliance with the MD and the increase in BMI (regression coefficients [b] and their confidence intervals (CI ([95% CI] and weight gain (Odds ratios [OR] and their 95% CI during pregnancy. Results: Women with a high baseline adherence to the Mediterranean diet gained less weight during pregnancy (b -1.54; CI 95% -2.53 to -0.56 than women with poor adherence. One point increase in the adherence to this diet during pregnancy was associated with an enhanced probability of appropriate weight gain (OR 1.39; CI 95%1.06 to 1.82. Conclusions: A high baseline adherence to the MD may protect against overweight and obesity during pregnancy. Intensifying this habit during gestation can increase the probability of an appropriate weight gain.

    Today's greatest challenge in accelerator-based neutrino physics is to measure the mixing angle \\thonethree\\ which is known to be much smaller than the solar mixing angle \\thonetwo\\ and the atmospheric mixing angle \\thtwothree . A non-zero value of the angle \\thonethree\\ is a prerequisite for observing CP violation in neutrino mixing. In this paper, we discuss a deep-sea neutrino experiment with 1.5~Mt fiducial target mass in the Gulf of Taranto with the prime objective of measuring \\thonethree. The detector is exposed to the CERN neutrino beam to Gran Sasso in off-axis geometry. Monochromatic muon-neutrinos of $\\approx 800$~MeV energy are the dominant beam component. Neutrinos are detected through quasi-elastic, charged-current reactions in sea water; electrons and muons are detected in a large-surface, ring-imaging Cherenkov detector. The profile of the seabed in the Gulf of Taranto allows for a moveable experiment at variable distances from CERN, starting at 1100 km. From the oscillatory pattern of the dis...

  14. Groundwater salinity and hydrochemical processes in the volcano-sedimentary aquifer of La Aldea, Gran Canaria, Canary Islands, Spain.

    The origin of the groundwater salinity and hydrochemical conditions of a 44km(2) volcano-sedimentary aquifer in the semi-arid to arid La Aldea Valley (western Gran Canaria, Spain) has been studied, using major physical and chemical components. Current aquifer recharge is mainly the result of irrigation return flows and secondarily that of rainfall infiltration. Graphical, multivariate statistical and modeling tools have been applied in order to improve the hydrogeological conceptual model and identify the natural and anthropogenic factors controlling groundwater salinity. Groundwater ranges from Na-Cl-HCO3 type for moderate salinity water to Na-Mg-Cl-SO4 type for high salinity water. This is mainly the result of atmospheric airborne salt deposition; silicate weathering, and recharge incorporating irrigation return flows. High evapotranspiration produces significant evapo-concentration leading to relative high groundwater salinity in the area. Under average conditions, about 70% of the water used for intensive agricultural exploitation in the valley comes from three low salinity water runoff storage reservoirs upstream, out of the area, while the remaining 30% derives from groundwater. The main alluvial aquifer behaves as a short turnover time reservoir that adds to the surface waters to complement irrigation water supply in dry periods, when it reaches 70% of irrigation water requirements. The high seasonality and intra-annual variability of water demand for irrigation press on decision making on aquifer use by a large number of aquifer users acting on their own.

    In many arid and semi-arid areas, intensive cultivation is practiced despite water commonly being a limiting factor. Often, irrigation water is from local aquifers or imported from out-of-area aquifers and surface reservoirs. Irrigation return flows become a significant local recharge source, but they may deteriorate aquifer water quality. La Aldea valley, located in the western sector of Gran Canaria Island (Atlantic Ocean), is a coastal, half-closed depression in altered, low-permeability volcanics with alluvium in the gullies and scree deposits over a large part of the area. This area is intensively cultivated. Irrigation water comes from reservoirs upstream and is supplemented (average 30 %) by local groundwater; supplementation goes up to 70 % in dry years, in which groundwater reserves are used up to exhaustion if the dry period persists. Thus, La Aldea aquifer is key to the water-supply system, whose recharge is mostly from return irrigation flows and the scarce local rainfall recharge on the scree formations, conveyed to the gully deposits. To quantify the hydrogeological conceptual model and check data coherence, a simplified numerical model has been constructed, which can be used as a tool to help in water management.

    Citrus medica cv. 'liscia' and C. medica cv. 'rugosa' are two taxa of citron, belonging to the biodiversity of South Italy, in particular of Amalfi Coast, in the Campania region. The chemical composition of the essential oils (EOs) from fruit peels of both C. medica cultivars was studied by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analyses. In all, 100 compounds were identified, 82 for C. medica cv. 'liscia', accounting for 91.4% of the total oil, and 88 for C. medica cv. 'rugosa', accounting for 92.0% of the total oil. Monoterpene hydrocarbons are the main constituents in both oils of C. medica cv. 'liscia' (79.1%) and C. medica cv. 'rugosa' (80.2%). In both oils, limonene (67.2%-62.8%) and camphene (8.5%-10.9%) are the main constituents. The antimicrobial activity of the EOs was assayed against some bacterial strains: Bacillus cereus (DSM 4313), Bacillus cereus (DSM 4384), Staphylococcus aureus (DSM 25693), Pseudomonas aeruginosa (ATCC 50071), and Escherichia coli (DSM 8579). Low concentrations of C. medica cv. 'rugosa' EO showed an inhibitory effect on P. aeruginosa and higher concentrations inhibited more B. cereus (4384) and E. coli than S. aureus. The cytotoxicity of the EO was evaluated against SH-SY5Y cell line. The influence of the EO on the expression of adenylate cyclase 1 (ADCY1) was also studied. The antimicrobial activity registered confirm their traditional uses as food preserving agents and led us to hypothesize the possible use of these oils as antimicrobials. The alterations in ADCY1 expression suggested a role for limonene in effects on the central nervous system.

    Purpose: Accurate detection of pulmonary nodules remains a technical challenge in computer-aided diagnosis systems because some nodules may adhere to the blood vessels or the lung wall, which have low contrast compared to the surrounding tissues. In this paper, the analysis of typical shape features of candidate nodules based on a shape constraint Chan–Vese (CV) model combined with calculation of the number of blood branches adhered to nodule candidates is proposed to reduce false positive (FP) nodules from candidate nodules. Methods: The proposed scheme consists of three major stages: (1) Segmentation of lung parenchyma from computed tomography images. (2) Extraction of candidate nodules. (3) Reduction of FP nodules. A gray level enhancement combined with a spherical shape enhancement filter is introduced to extract the candidate nodules and their sphere-like contour regions. FPs are removed by analysis of the typical shape features of nodule candidates based on the CV model using spherical constraint and by investigating the number of blood branches adhered to the candidate nodules. The constrained shapes of CV model are automatically achieved from the extracted candidate nodules. Results: The detection performance was evaluated on 127 nodules of 103 cases including three types of challenging nodules, which are juxta-pleural nodules, juxta-vascular nodules, and ground glass opacity nodules. The free-receiver operating characteristic (FROC) curve shows that the proposed method is able to detect 88% of all the nodules in the data set with 4 FPs per case. Conclusions: Evaluation shows that the authors’ method is feasible and effective for detection of three types of nodules in this study.

    Full Text Available High percentage of callus induction at 97% was obtained when seeds of rice (Oryza sativa L. cv. RD6 were cultured on modified N6 medium supplemented with 3% (w/v sucrose, 22.5 μM 2,4-D and 0.8% agar under light condition. The suitable regeneration medium was N6 medium supplemented with 3% (w/v sucrose, 2.5 μM IAA, 18 μM BA and 0.8% agar. A test had been performed to determine the effect of antibiotics on the regeneration of rice cv. RD6. It was found that kanamycin concentration up to 150 mg l-1 and hygromycin concentration at 10 mg l-1 were effective for selection of transformants. Cefotaxime and carbenicillin concentration up to 250 mg l-1 had the highest phytotoxicity to plant regeneration. Agrobacterium-mediated gene transfer protocols for rice cv. RD6 were performed using A. tumefaciens strain LBA4404, which harbored the plasmid pBI121 containing genes for β- glucuronidase (GUS and kanamycin resistance (nptII, and strain EHA105, which harbored plasmid pCAMBIA1301 containing genes for β-glucuronidase (GUS and hygromycin resistance (hptII. GUS activities were found in rice calli after co-cultivation. A number of morphologically normal fertile transgenic rice plants were obtained. Stable integration, expression and inheritance of transgenes were demonstrated by molecular and genetic analysis of transgenic plants in T0 and T1 generation. Mendelian segregation was observed in T1 progeny.

    Full Text Available Level of affi nity between grapevine rootstock and Vitis vinifera as scion, quality of reproductive materials and technological actions in grapevine rootstock production process determine success in grapevine rootstock production in large extent. Practical training showed that difference in level of compatibility between grapevine rootstock and grafted Vitis vinifera cultivars are existing. Direct effects of these differences are unequal yield of fi rst class grafted grapevine rootlings. In this paper, level of compatibility in nursery between clones of cv. Chardonnay BCL 75, VCR4 and cv. Merlot R18, MCL 519 and grapevine rootstocks Kober 5BB (Vitis berlandieri x V. riparia, SO4 (V. berlandieri x V. riparia and 41B (Chasselas x V.berlandieri were investigated. The trial was conducted in commercial grapevine nursery located in Velika Drenova, Serbia. As an index of compatibility, grade of high quality grapevine grafted rootlings, dry matter in mature shoots and root system development were used. Grafting was done by `tongue grafting` indoor technique. Stratifi cation was done in sand, on temperature of the stratifi cation material of 26-28oC, and humidity of around 90%. Grafted cuttings were waxed twice: before stratifi cation, and before planting in the nursery. Grafted rootlings were classed in two classes according to regulations of quality, (Yugoslav Offi cial Register, 26/79. Grafted rootlings that did not satisfi ed standard criteria were discarded. Both clones of cv. Chardonnay gave the highest percentage of I class grafted rootlings on grapevine rootstock 41B: clone BCL 75 – 60% and clone VCR4 – 61%. In the same combination, those grapevine grafted rootlings had the highest weight of the root system. Lower percentage of obtained I class grafted rootlings was established on rootstock Kober 5BB, while statistically signifi cantly lower yields were obtained on grapevine rootstock SO4: clone BCL75 – 43% and clone VCR4 – 48%.

    Full Text Available Enquanto que a maioria dos historiadores remete a origem das atuais relações raciais à escravidão colonial, Marixa Lasso argumenta que foi durante a Era das Revoluções das lutas anticoloniais americanas que nações com histórias semelhantes de colonialismo, escravidão e racismo desenvolveram distintos imaginários raciais modernos. Em particular, examina-se a origem da ideologia nacionalista de igualdade e harmonia racial (o mito da democracia racial, conforme a denominação do século XIX, durante as guerras de independência hispano-americanas. Sua análise enfoca a Gran Colombia, uma das regiões-chave na luta pela independência hispano-americana, onde a guerra transformou o imaginário racial de duas maneiras. A guerra propiciou a idéia de igualdade racial unindo a força emocional do patriotismo, transformando-a numa ideologia nacionalista que transcendia diferenças partidárias e regionais. Ao mesmo tempo, o fantasma de outro tipo de guerra, a “guerra de raças”, criou diferenças fundamentais entre o que se constituía como um discurso racial legítimo e um discurso racial ilegítimo. O medo da guerra de raças restringiu as ações políticas dos afro-descendentes e limitou suas oportunidades para denunciar a permanência de persistentes preconceitos e padrões de discriminações informais

    We report the mineralogy, petrography, and in situ measured 26Al-26Mg systematics in chondrules from the least metamorphosed CV3 (Vigarano-type) chondrites, Kaba and Yamato (Y) 980145. Two Y 980145 chondrules measured show no resolvable excesses in 26Mg (26Mg∗), a decay product of a short-lived (t1/2 ∼0.7 Ma) radionuclide 26Al. Plagioclase in one of the chondrules is replaced by nepheline, indicative of thermal metamorphism. The lack of 26Mg∗ in the Y 980145 chondrules is most likely due to disturbance of their 26Al-26Mg systematics during the metamorphism. Although Kaba experienced extensive metasomatic alteration (core in this body suggested from the paleomagnetic records of Allende [Carporzen et al.

    Grape juice and grape skin extracts are important commercial source of polyphenolic compounds which exert different functional properties such as color potential, antimicrobial, antioxidant activity, and health benefits. In this paper we describe a sensitive and specific assay for determination of bioactive polyphenolic compounds in Campbell Early (Vitis labrusca cv. baile). Five polyphenolic components were separated on an Agilent Zorbax Extend C18 Column (250 mm x 4.6 mm x 5 μm) and detected by a diode array detector. The mobile phase was composed of (a) aqueous phosphoric acid (0.2%, v/v); and (b) acetonitrile using a gradient elution. Analytes were performed at 25 degrees C with a flow rate of 0.8 ml/min and UV detection at 280, 360, and 520 nm. All calibration curves showed good linear regression (r2 ≥ 0.9999) within tested ranges. Overall intra- and inter-day variations were less than 1.90%, and the average recoveries were 95.5-105% for analytes. The antioxidant activity determined by DPPH radical assay, ranged from 86-105 for extracts, and 165-252 for studied standards (μM trolox/100 g dry wt.). The proposed method would be sensitive enough and reliable for quality control in functional food and modernization of Campbell Early (Vitis labrusca cv. baile) as potent antioxidant agents.

    Plasmalemmal vesicle associated protein (Plvap/PV1) is a structural protein required for the formation of the stomatal diaphragms of caveolae. Caveolae are plasma membrane invaginations that were implicated in SV40 virus entry in primate cells. Here we show that de novo Plvap/PV1 expression in CV-1 green monkey epithelial cells significantly reduces the ability of SV40 virus to establish productive infection, when cells are incubated with low concentrations of the virus. However, in presence of high viral titers PV1 has no effect on SV40 virus infectivity. Mechanistically, PV1 expression does not reduce the cell surface expression of known SV40 receptors such as GM1 ganglioside and MHC class I proteins. Furthermore, PV1 does not reduce the binding of virus-like particles made by SV40 VP1 protein to the CV-1 cell surface and does not impact their internalization when cells are incubated with either high or low VLP concentrations. These results suggest that PV1 protein is able to block SV40 infectivity at low but not at high viral concentration either by interfering with the infective internalization pathway at the cell surface or at a post internalization step.

    In the present work the first results obtained with the low energy proton beam of CV-28 at IEN/CNEN and the prototype of a computerized tomography device developed in UFTPR are presented. The system installed in the scatterings chamber of the cyclotron line 3 includes the proton scatter, turntable with translation (1st generation CT scheme), the set of collimators for the secondary proton beam formation and the Si(Li) ORTEC detector. The main parameters of the tomography turntable and the collimators were chosen based on computer simulations with SRIM2006 and GEANT4. A cylindrical glass tube was used as the irradiated sample. On this stage, only the translation of the turntable perpendicular to the proton beam direction was fulfilled. The measured proton energy spectra have, in general, a predicted behavior. However, the experiment revealed some problems with the secondary proton beam formation that should be solved prior to obtain a first pCT image at CV-28. (author)

    2010-10-01

    For multi-camera calibration systems, a method based on OpenCV and multi-view registration combining calibration algorithm is proposed. First of all, using a Zhang's calibration plate (8X8 chessboard diagram) and a number of cameras (with three industrial-grade CCD) to be 9 group images shooting from different angles, using OpenCV to calibrate the parameters fast in the camera. Secondly, based on the corresponding relationship between each camera view, the computation of the rotation matrix and translation matrix is formulated as a constrained optimization problem. According to the Kuhn-Tucker theorem and the properties on the derivative of the matrix-valued function, the formulae of rotation matrix and translation matrix are deduced by using singular value decomposition algorithm. Afterwards an iterative method is utilized to get the entire coordinate transformation of pair-wise views, thus the precise multi-view registration can be conveniently achieved and then can get the relative positions in them(the camera outside the parameters).Experimental results show that the method is practical in multi-camera calibration .

    2014-02-01

    We explore the relevance of Heterogeneous System Architecture (HSA) in Computer Vision, both as a long term vision, and as a near term emerging reality via the recently ratified OpenCL 2.0 Khronos standard. After a brief review of OpenCL 1.2 and 2.0, including HSA features such as Shared Virtual Memory (SVM) and platform atomics, we identify what genres of Computer Vision workloads stand to benefit by leveraging those features, and we suggest a new mental framework that replaces GPU compute with hybrid HSA APU compute. As a case in point, we discuss, in some detail, popular object recognition algorithms (part-based models), emphasizing the interplay and concurrent collaboration between the GPU and CPU. We conclude by describing how OpenCL has been incorporated in OpenCV, a popular open source computer vision library, emphasizing recent work on the Transparent API, to appear in OpenCV 3.0, which unifies the native CPU and OpenCL execution paths under a single API, allowing the same code to execute either on CPU or on a OpenCL enabled device, without even recompiling.

    Plants in alpine habitats are exposed to many environmental stresses, in particular temperature and radiation extremes. Recent field experiments on Arnica montana L. cv. ARBO indicated pronounced altitudinal variation in plant phenolics. Ortho-diphenolics increased with altitude compared to other phenolic compounds, resulting in an increase in antioxidative capacity of the tissues involved. Factors causing these variations were investigated by climate chamber (CC) experiments focusing on temperature and ultraviolet (UV)-B radiation. Plants of A. montana L. cv. ARBO were grown in CCs under realistic climatic and radiation regimes. Key factors temperature and UV-B radiation were altered between different groups of plants. Subsequently, flowering heads were analyzed by HPLC for their contents of flavonoids and caffeic acid derivatives. Surprisingly, increased UV-B radiation did not trigger any change in phenolic metabolites in Arnica. In contrast, a pronounced increase in the ratio of B-ring ortho-diphenolic (quercetin) compared to B-ring monophenolic (kaempferol) flavonols resulted from a decrease in temperature by 5 degrees C in the applied climate regime. In conclusion, enhanced UV-B radiation is probably not the key factor triggering shifts in the phenolic composition in Arnica grown at higher altitudes but rather temperature, which decreases with altitude.

    This subchronic duration feeding study evaluated the nutritional and health status of rats fed diets containing CV127 at incorporation levels of 11% and 33%. For control comparisons, rats were also exposed to similar incorporation levels of the near isogenic conventional soybean variety (Conquista) and two other conventional soybean varieties (Monsoy, Coodetec). In spite of phenotypic differences among these four soybean varieties, there were no quantitative differences in their respective proximate and other compositional properties, including proteins, amino acids, antinutrients and nutritional cofactors. All diets were prepared by blending the respective processed soybean meal with ground Kliba maintenance meal at high (33%) and low (11%) incorporation levels, and the blended diets were fed to Wistar rats for about 91 days. Although there were some isolated parameters indicating statistically significant changes, these lacked consistency and a plausible mechanism and were thus assessed to be incidental. The totality of results demonstrate that CV127 soybeans are similar with respect to their nutritional value and systemic effects as its near isogenic conventional counterpart, as well as other conventional soybean varieties. Hence, introduction of AHAS gene into soybeans does not substantially alter its compositional properties, nor adversely affect its nutritional or safety status to mammals.

    Full Text Available The use of pulse solutions containing antimicrobials has been reported, but more research is necessary. To increase vase life and to study their effect on opening inflorescences, silver nanoparticles were used in vase solutions for cv. Puma Chrysanthemum stems. The nanoparticles were synthesized biologically using Chenopodium ambrosioides L. applied at concentrations of 0.01, 0.05, 0.1, 0.5, 1, and 5 mM and compared with a control. Treatments were replicated five times. The stems were cut to 50 cm and observed until the end of their vase life. Low concentrations of silver nanoparticles promoted inflorescence opening and leaf yellowing, while the control leaves remained green, but there was a lower degree of inflorescence opening. High concentrations of silver nanoparticles (0.5, 1, and 5 mM caused senescence due to low water uptake through the stems. Statistical differences in inflorescence opening and diameter, bacterial growth (CFU mL−1 in vase solutions, fresh weight, water uptake, and vase life were found among treatments. Longer vase life and less weight loss were observed in the stems exposed to low concentrations of silver nanoparticles. Low concentrations of silver nanoparticles promoted inflorescence opening and increased vase life of Chrysanthemum cv. Puma.

    The dry Chaco, a semiarid thorn forest, is experiencing some of the highest deforestation rates globally, coupled with the fact that small-bodied fish are at the highest risk of extinction, the killifish inhabiting this region may be some of the most threatened taxa. Yet, aspects of ecology and life history for Neotropical killifishes in the Bolivian Gran Chaco region are completely lacking, and basic life-history data is of critical importance for the design and implementation of conservation measures. Collections were conducted during the early (January 2011) and late (March-April 2011) rainy season using an area-based sampler and dip net surveys. Fish standard length and body depth were measured as well as the number of oocytes per size class, mean oocyte diameter per size class, and total fecundity for the females of each species. A total of 490 specimens of rivulids were captured; Austrolebias vandenbergi: 85 females, 105 males and 39 juveniles, and N. ornatipinnis: 62 females, 113 males, 86 juveniles. Sexual size dimorphism, absolute fecundity, oocyte developmental stages, oocyte diameter, and population sex ratios were determined for each species. Both species exhibited sexual size dimorphism. Male A. vandenbergi exhibited longer standard length (mean +/- SD; males: 27.07 +/- 3.89mm, females: 23.6 +/- 2.02mm) and body depth (males: 8.9 +/- 1.7mm, females: 7.2 +/- 1.1 mm) as compared to females. Male N. ornatipinnis had a similar pattern for both standard length (males: 26.0 +/- 7.1mm, females: 19.1 +/- 5.83mm) and body depth (males: 5.6 +/- 1.9mm, females: 4.7 +/- 1.0mm). Austrolebias vandenbergi had fewer and smaller oocytes per female (47 +/- 31.6) than N. ornatipinnis (206 +/- 131.2). There was a positive relationship between fecundity and female body size in both species. The presence of multiple developmental stages of oocytes (immature, maturing, and mature) suggest that both species of rivulids exhibit fractional spawning, a reproductive strategy that

  8. The emplacement history of a remarkable heterogeneous, chemically zoned, rheomorphic and locally lava-like ignimbrite: 'TL' on Gran Canaria

    2002-06-01

    Ignimbrite 'TL' on Gran Canaria is a complex, compositionally zoned rheomorphic tuff, that locally exhibits features previously considered to be diagnostic of lavas. It is made up of two locally overlapping lobes of ignimbrite that were emplaced during a single eruptive episode. The eastern lobe is high-grade, with rheomorphic zones and localised patches that are lava-like. The western lobe is extremely high-grade, more extensively lava-like, and welded to its top surface. Both parts are zoned, with a basal comendite-rich zone grading up, through a mixed zone, into an upper trachyte-rich zone. Lithic contents, and the relative proportions of comendite and trachyte pyroclasts vary with height. Each comendite-rich zone is vitroclastic, whereas each trachyte-rich zone is partly lava-like with local gradations into vitroclastic ignimbrite. Mixed zones are intermediate in character, and locally show compositional banding. Gradational zoning in massive ignimbrite, best seen in lower strain zones, and welding fabrics that are pervasively lineated and oblique to bedding, suggest that deposition was sustained, agglutination was rapid, and rheomorphic deformation began during the sustained deposition. The viscosity and porosity of the agglutinate varied with height because successively deposited pyroclast populations varied in grainsize, composition and temperature. The hot agglutinate continued to compact and shear downslope after the density currents had dissipated, causing further rheomorphic folding, thrusting, attenuation and autobrecciation. The western lobe locally overlies the partly welded top of the eastern lobe, in part because it advanced rheomorphically across it for at least 300 m. Hot-state loading and auto-intrusion occurred due to unstable density layering in the chemically zoned agglutinate. Deformation behaviour changed during cooling and degassing, and because of heat transfer between juxtaposed agglutinates, and localised retention of dissolved volatiles

    Full Text Available Exploratory monitoring of radon is conducted at one location at the deep underground Gran Sasso National Laboratory (LNGS. Measurements (15-min resolution are performed over a time span of ca. 600 days in the air of the surrounding calcareous country rock. Utilizing both alpha and gamma-ray detectors systematic and recurring radon signals are recorded. Two primary signal types are determined: (a non-periodic Multi-Day (MD signals lasting 2–10 days, and (b Daily Radon (DR signals – which are of a periodic nature exhibiting a primary 24-h cycle. The local ancillary environmental conditions (P, T seem not to affect radon in air monitored at the site. Long term patterns of day-time measurements are different from the pattern of night-time measurements indicating a day-night modulation of gamma radiation from radon in air. The phenomenology of the MD and DR signals is similar to situations encountered at other locations where radon is monitored with a high time resolution in geogas at upper crustal levels. In accordance with recent field and experimental results it is suggested that a components of solar irradiance is affecting the radiation from radon in air, and this influence is further modulated by the diurnal rotation of Earth. The occurrence of these radon signals in the 1 km deep low radiation underground geological environment of LNGS provides new information on the time variation of the local radiation environment. The observations and results place the LNGS facility as a high priority location for performing advanced investigations of these geophysical phenomena, due to its location and its infrastructure.

    Bolivia has a total of 47 species of Psittacidae, seven of which have been identified in our study site, the semiarid Gran Chaco of the Isoso. One species, the blue-fronted parrot (Amazona aestiva), is frequently captured by local Isoseño Guaraní Indians for exploitation on the national and international market. These birds are often temporarily housed in small villages under unhygienic conditions with poultry and other domestic species. On occasion, these parrots escape back to the wild. Additionally, many of these birds are kept as pets or are used to lure wild. parrots within slingshot range for subsequent capture. In this study, we evaluated the health status, including the level of exposure to selected infectious agents, in the wild-caught captive birds and free-ranging birds. Physical examinations were performed, and blood was collected, from 54 live birds (20 captive and 34 free-ranging). Feces were collected from 15 birds (seven captive and eight free-ranging). Necropsies were also performed on four recently dead wild-caught birds. On serologic testing, no birds were found to have antibodies to avian influenza virus, Chlamydophila psittaci, infectious bronchitis virus, infectious bursal disease virus, infectious laryngotracheitis virus, Marek's disease virus, paramyxovirus-1, paramyxovirus-2, paramyxovirus-3, polyomavirus, eastern equine encephalitis virus, western equine encephalitis virus, or Venezuelan equine encephalitis virus. Positive antibody titers were found for psittacine herpesvirus (8/44, 18.2%), Aspergillus spp. (3/51, 5.9%), and Salmonella pullorum (33/49, 67.3%). All three of the birds that tested antibody positive for Aspergillus spp. were captive, whereas six of the eight and 15 of the 33 birds that tested positive for psittacine herpesvirus and S. pullorum, respectively, were wild.

    Full Text Available Ei jardín y la fiesta compartieron, a lo largo del Renacimiento y el Barroco, importantes elementos de coincidencia en sus fuentes de inspiración, empleo de recursos expresivos, pautas de evolución, etc. Ambas realidades fueron, además, creaciones artificiales que recreaban espacios imaginarios repletos de mensajes. A través de las fiestas celebradas en las casas de la nobleza, del empleo del espacio natural como improvisado marco festivo, o de la integración más o menos artificiosa de la naturaleza en el espacio urbano, ésta se convierte en gran teatro de la Corte, aportando interesantes peculiaridades al modo en que la relación entre fiesta, naturaleza y ciudad se desarrolló en los siglos XVI y XVII.During the Renaissance and Barroque periods, gardens and festivities be inspired in the similar artistic and literary referencies and following de same evolution and expresión's systems.

Throw the festivities that been place in the nobility hauses, the use of the natural space as an improvised festival place, or the mixed between the town and natural elements in the ephemeral decoration, we can see the way as the natural turned into a Great Court theatre during the XVIth and XVIIth centuries. The study of these relations is interesting to understand the way as they were developed at that time.

    Full Text Available En 1937 el gobierno argentino decide desalojar y trasladar a la tribu Nahuelpán bajo acusaciones de extranjería e in-civilización. Luego de seis años, la medida es revisada y se inicia un proceso de restitución parcial de las tierras involucradas seleccionándose desde el estado a quienes se continuaría reconociendo como "tribu" Nahuelpán. A partir de este caso enmarcado en el contexto de las relaciones establecidas por las comunidades indígenas del territorio nacional de Chubut con las autoridades nacionales y las redes locales de poder, se propone un análisis del proceso de construcción del espacio social para los pueblos originarios en la matriz estado-nación-territorio en el período que va de la gran crisis del '30 al primer gobierno peronista. Se abordan en particular los mecanismos de tribalización en la interfase entre políticas oficiales y agencia aborigen.In 1937, the Argentine government decided to displace and remove the Nahuelpán tribe accused of foreign and uncivilized behavior. Six years later this measure was reviewed starting a process of partial land restitution in which the state selected who will continue to be considered as member of the above mentioned tribe. Focusing in that case, framed by the relationship established between indigenous communities of the national territory of Chubut and state authorities or local nets of power, this article analyzes the process leading to the construction of a social space in the state-nation-territory matrix since the 1930' great crisis until the first period of President Juan Perón.

  14. New constraints on the magnetic history of the CV parent body and the solar nebula from the Kaba meteorite

    2016-12-01

    Recent paleomagnetic studies of Allende CV chondrite as well as thermal modeling suggest the existence of partially differentiated asteroids with outer unmelted and variably metamorphosed crusts overlying differentiated interiors. To further constrain the magnetic history of the CV parent body, we report here paleomagnetic results on Kaba CV chondrite. This meteorite contains 11 wt% pseudo-single domain magnetite, making it a rock with an excellent paleomagnetic recording capacity. Kaba appears to carry a stable natural remanent magnetization acquired on its parent body upon cooling in an internally generated magnetic field of about 3 μT from temperatures below 150 °C during thermal metamorphism about 10 to several tens of Myr after solar system formation. This strengthens the case for the existence of a molten advecting core in the CV parent body. Furthermore, we show that no significant magnetic field (i.e. lower than ∼ 0.3 μT) was present when aqueous alteration took place on the Kaba parent body around 4 to 6 Myr after solar system formation, suggesting a delay in the onset of the dynamo in the CV parent body and confirming that nebular fields had already decayed at that time.

    Monthly stream water calcium and Gran alkalinity concentration data from 11 sub-catchments of the Nether Beck in the English Lake District have been used to appraise the transferability of the Scottish, River Dee-based G-BASH model. Readily available riparian zone geochemistry and flow paths were used initially to predict minimum and mean stream water concentrations at the Nether Beck, based on calibration equations from the River Dee catchment data. Predicted values significantly exceeded observed values. Differences in runoff between the two areas, leading to a dilution effect in the Nether Beck, explained most of the difference between observed and predicted values. Greater acid deposition in the Lake District also reduced stream water Gran alkalinity concentrations in that area. If regional differences in precipitation, evapotranspiration and pollutant deposition are incorporated into the model, it may then be used reliably to predict catchment susceptibility to acidification over a wide regional (national) scale.

    Modeling of volcanic morphometry provides reliable measurements of parameters that assist in the determination of volcanic landform degradation. Variations of the original morphology enable the understanding of patterns affecting erosion and their development, facilitating the assessment of associated hazards. A total of 24 volcanic Holocene eruptions were identified in the island of Gran Canaria (Canary Islands, Spain). 87% of these eruptions occurred in a wet environment while the rest happened in a dry environment. 45% of Holocene eruptions are located along short barrancos (S-type, less than 10 km in length), 20% along large barrancos (L-type, 10-17 km in length) and 35% along extra-large barrancos (XL-type, more than 17 km in length). The erosional history of Holocene volcanic edifices is in the first stage of degradation, with a geomorphic signature characterized by a fresh, young cone with a sharp profile and a pristine lava flow. After intensive field work, a careful palaeo-geomorphological reconstruction of the 24 Holocene eruptions of Gran Canaria was conducted in order to obtain the Digital Terrain Models (DTMs) of the pre- and post-eruption terrains. From the difference between these DTMs, the degradation volume and the incision rate were obtained. The denudation of volcanic cones and lava flows is relatively independent both their geographical location and the climatic environment. However, local factors, such as pre-eruption topography and ravine type, have the greatest influence on the erosion of Holocene volcanic materials in Gran Canaria. Although age is a key factor to help understand the morphological evolution of monogenetic volcanic fields, the Gran Canaria Holocene volcanism presented in this paper demonstrates that local and regional factors may determine the lack of correlation between morphometric parameters and age. Consequently, the degree of transformation of the volcanic edifices evolves, in many cases, independently of their age.

    This paper presents a direct comparison between two satellite time transfer techniques: common-view (CV) of satellites from the global positioning system (GPS) constellation, and time transfer by laser link (T2L2) through the low orbiting satellite Jason-2. We describe briefly both techniques, together with two independent relative calibration campaigns of the links involving four European laboratories. Between the same remote time scale reference points, the mean values of the calibrated differences between GPS CV and T2L2 are below 240 ps, with standard deviations below 500 ps, mostly due to GPS CV. Almost all sample deviations from 0 ns are within the combined uncertainty estimates. Despite the relatively small number of common points obtained, due to the fact that T2L2 is weather dependent, these results provide an unprecedented sub-ns consistency between two independently calibrated microwave and optical satellite time transfer techniques.

    Monthly stream water calcium and Gran alkalinity concentration data from 11 sub-catchments of the Nether Beck in the English Lake District have been used to appraise the transferability of the Scottish, River Dee-based G-BASH model. Readily available riparian zone geochemistry and flow paths were used initially to predict minimum and mean stream water concentrations at the Nether Beck, based on calibration equations from the River Dee catchment data. Predicted values significantly exceeded observed values. Differences in runoff between the two areas, leading to a dilution effect in the Nether Beck, explained most of the difference between observed and predicted values. Greater acid deposition in the Lake District also reduced stream water Gran alkalinity concentrations in that area. If regional differences in precipitation, evapotranspiration and pollutant deposition are incorporated into the model, it may then be used reliably to predict catchment susceptibility to acidification over a wide regional (national) scale. - A modified G-BASH model predicts calcium and Gran alkalinity in streams at a national scale, taking account of regional deposition and climatic variations.

The apparent chemical diffusion coefficients of lithium in the films, D-tilde{sub Li}, were measured by cyclic voltammetry (CV), galvanostatic intermittent titration technique (GITT), and electrochemical impedance spectroscopy (EIS). The average D-tilde{sub Li} values calculated from CV results were in the order of 10{sup -14} cm{sup 2} s{sup -1}. The D-tilde{sub Li} values obtained by GITT, and EIS techniques were in the range of 10{sup -14}-10{sup -18} cm{sup 2} s{sup -1}, 10{sup -14}-10{sup -18} cm{sup 2} s{sup -1}, respectively. The D-tilde{sub Li} values obtained by the two methods show a minimum point at x {approx} 0.5 for Li{sub 1-x}FePO{sub 4}. However, the overpotential values of the LiFePO{sub 4} thin film electrodes obtained from the GITT results and the diffusion impedance deduced from the impedance spectra also show the minimum values at x {approx} 0.5 for Li{sub 1-x}FePO{sub 4}. This contradict could be caused by the improper use of GITT and EIS techniques for measuring the chemical diffusion coefficient of Li in Li{sub 1-x}FePO{sub 4} which constitutes two phase, i.e., LiFePO{sub 4} and FePO{sub 4} in this region.

  14. Chemical and physical studies of type 3 chondrites 12: The metamorphic history of CV chondrites and their components

    The induced thermoluminescence (TL) properties of 16 CV and CV-related chondrites, four CK chondrites and Renazzo (CR2) have been measured in order to investigate their metamorphic history. The petrographic, mineralogical and bulk compositional differences among the CV chondrites indicate that the TL sensitivity of the approximately 130 C TL peak is reflecting the abundance of ordered feldspar, especially in chondrule mesostasis, which in turn reflects parent-body metamorphism. The TL properties of 18 samples of homogenized Allende powder heated at a variety of times and temperatures, and cathodoluminescence mosaics of Axtell and Coolidge, showed results consistent with this conclusion. Five refractory inclusions from Allende, and separates from those inclusions, were also examined and yielded trends reflecting variations in mineralogy indicative of high peak temperatures (either metamorphic or igneous) and fairly rapid cooling. The CK chondrites are unique among metamorphosed chondrites in showing no detectable induced TL, which is consistent with literature data that suggests very unusual feldspar in these meteorites. Using TL sensitivity and several mineral systems and allowing for the differences in the oxidized and reduced subgroups, the CV and CV-related meteorites can be divided into petrologic types analogous to those of the ordinary and CO type 3 chondrites. Axtell, Kaba, Leoville, Bali, Arch and ALHA81003 are type 3.0-3.1, while ALH84018, Efremovka, Grosnaja, Allende and Vigarano are type 3.2-3.3 and Coolidge and Loongana 001 are type 3.8. Mokoia is probably a breccia with regions ranging in petrologic type from 3.0 to 3.2. Renazzo often plots at the end of the reduced and oxidized CV chondrite trends, even when those trends diverge, suggesting that in many respects it resembles the unmetamorphosed precursors of the CV chondrites. The low-petrographic types and low-TL peak temperatures of all samples, including the CV3.8 chondrites, indicates metamorphism

    Enzyme browning is the main challenge in the preparation of fresh apple juice. The influence of sonication on browning, as well as polyphenols and antioxidant activity of fresh apple juice was investigated. It was found that ultrasound can inhibit the browning of fresh apple (Malus pumila Mill, cv. Red Fuji) juice, but decreased the contents of total phenolic content (TPC), total flavonoid content (TFC) and chlorogenic acid and reduced the antioxidant activity. On the whole, ultrasound technology cannot be used to the antibrowning of fresh apple (Malus pumila Mill, cv. Red Fuji) juice.

    Research has shown that the risk of hot spots in the drinking water pipes is very high. Hot spots are, for example, caused by central heating pipes that are too close to the water pipes. The water pipes may be 25 C for a long period, thus creating the risk of legionella growth. The various disciplines need to be careful in the design stage and building stage to prevent such situations from occurring. [Dutch] Onderzoek heeft uitgewezen dat het risico op 'hotspots' in de drinkwaterleidingen erg groot is. Hotspots worden bijvoorbeeld veroorzaakt door cv-leidingen die te dicht in de buurt van waterleidingen lopen. Die waterleidingen kunnen dan langdurig warmer zijn dan 25C en daardoor gevaar opleveren voor legionellagroei. Het vereist zorg van meerdere disciplines in de ontwerpfase en de bouwfase om deze situaties te vermijden.

  19. Inducing gravitropic curvature of primary roots of Zea mays cv Ageotropic

    Moore, R.; Evans, M. L.; Fondren, W. M.

    1990-01-01

    Primary roots of the mutant 'Ageotropic' cultivar of Zea mays are nonresponsive to gravity. Their root caps secrete little or no mucilage and touch the root only at the extreme apex. A gap separates the cap and root at the periphery of the cap. Applying mucilage from normal roots or substances with a consistency similar to that of mucilage to tips of mutant roots causes these roots to become strongly graviresponsive. Gravicurvature stops when these substances are removed. Caps of some mutants secrete small amounts of mucilage and are graviresponsive. These results indicate that (a) the lack of graviresponsiveness in the mutant results from disrupting the transport pathway between the cap and root, (b) movement of the growth-modifying signal from the cap to the root occurs via an apoplastic pathway, and (c) mucilage is necessary for normal communication between the root cap and root in Zea mays cv Ageotropic.

    2014-09-15

    Grapes (Vitis vinifera, cv Sangiovese), harvested at standard commercial maturity, were treated for 36 h with ethylene (ET, 1000 ppm) or air (control, CT) before vinification. The composition of the grapes, must and wine was different in the CT and ET samples. In the ET wine, higher concentrations of specific phenol compounds, belonging to the classes of flavonols, anthocyanins, flavan-3-ols, and stilbenes, were detected. ET induced a significant change in the wine aroma profile by increasing free volatile categories such as phenols and fatty acids, and reducing the content of carbonyl compounds and, in particular, of esters. Less pronounced differences between CT and ET wines were observed in terms of glycosidically-bound volatile compounds. The activity of pectin methyl esterase and β-glucosidase was enhanced in ET-treated berry skins, suggesting that cell wall properties and changes in the hydrolytic activity are effective in modulating the composition of CT and ET wines.

    The cooling and ventilation group deals with a great number of supplies and installation contracts, as well as some service ones, in relation to the LHC project. In the course of the last years the group has increased its experience in the handling of these contracts in particular as a consequence of the difficult situations sometimes faced, which have been trying but enriching. This paper reviews some statistics on the performance of the CV contracts and draws some conclusions from a set of key cases. These cases can be helpful in identifying possible weak points during the different project phases (engineering, tendering and contracting, installation, etc.) and can provide a basis for the discussion of potential solutions.

    Two new ursolic acid triterpene derivatives, compounds 2 and 3, have been isolated from cv. Annurca apple fruit, a high-quality apple variety widely cultivated in southern Italy, together with the known 2-oxopomolic acid (1). The new compounds were identified by means of different spectroscopic techniques as 3-epi-2-oxopomolic acid (= (3alpha)-3,19-dihydroxy-2-oxours-12-en-28-oic acid; 2) and (1alpha)-1-hydroxy-3-oxours-12-en-28-oic acid (3). Compounds 1-3 were tested for their radical-scavenging activities with the aid of a 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay (Fig. 2). All three constituents showed activities similar to that of the reference antioxidant alpha-tocopherol (vitamin E).

    Full Text Available Aimed at the established telenanomanipulation system, the method of extracting location information and the strategies of probe operation were studied in this paper. First, the machine learning algorithm of OpenCV was used to extract location information from SEM images. Thus nanowires and probe in SEM images can be automatically tracked and the region of interest (ROI can be marked quickly. Then the location of nanowire and probe can be extracted from the ROI. To study the probe operation strategy, the Van der Waals force between probe and a nanowire was computed; thus relevant operating parameters can be obtained. With these operating parameters, the nanowire in 3D virtual environment can be preoperated and an optimal path of the probe can be obtained. The actual probe runs automatically under the telenanomanipulation system's control. Finally, experiments were carried out to verify the above methods, and results show the designed methods have achieved the expected effect.

    2014-03-01

    Thomas Jefferson National Accelerator Facility (TJNAF) uses superconducting radiofrequency (SRF) cavities to accelerate an electron beam. If theses cavities have a small particle or defect, it can degrade the performance of the cavity. The problem at hand is inspecting the cavity for defects, little bubbles of niobium on the surface of the cavity. Thousands of pictures have to be taken of a single cavity and then looked through to see how many defects were found. A C + + program with Open Source Computer Vision (OpenCV) was constructed to reduce the number of hours searching through the images and finds all the defects. Using this code, the SRF group is now able to use the code to identify defects in on-going tests of SRF cavities. Real time detection is the next step so that instead of taking pictures when looking at the cavity, the camera will detect all the defects.

TAF use a cardan shafts transmission from the gear box (CV to distribution box (CD. The distribution box split the movement thru axels or winch. The study applied the cardan theory on a specific case and based on the numeric results a few design modifications are proposed for reducing the angular velocity pulse on the CD input shaft. Theoretical results may have a significant importance in practice, impacting the reduction of transmission noise and vibrations - already claimed in the case of the distribution box for the current constructive solution. An original AutoLISP program are made in order to analyze and optimize the transmission, with graphical results.

    There are several leading theories on the processes that led to the formation of chondrites, e.g., sorting by mass, by X-winds, turbulent concentration, and by photophoresis. The juxtaposition of refractory inclusions (CAIs) and less refractory chondrules is central to these theories and there is much to be learned from their relative size distributions. There have been a number of studies into size distributions of particles in chondrites but only on relatively small scales primarily for chondrules, and rarely for both Calcium Aluminum-rich Inclusions (CAIs) and chondrules in the same sample. We have implemented macro-scale (25 cm diameter sample) and high-resolution microscale sampling of the Allende CV3 chondrite to create a complete data set of size frequencies for CAIs and chondrules.

    The altitudinal variation of the contents of secondary metabolites in flowering heads of Matricaria chamomilla L. (Asteraceae) was assessed. Plants of M. chamomilla cultivar BONA were grown in nine experimental plots at altitudes between 590 and 2,230 m at Mount Patscherkofel near Innsbruck/Austria. The amounts of flavonoids and phenolic acids were quantified by HPLC/DAD. For both flavonoids and phenolic acids positive (r = 0.559 and 0.587) and statistically significant (both p < 0.001) correlations with the altitude of the growing site were observed. The results are compared to previous results on Arnica montana L. cv. ARBO. Moreover, various ecological factors, which change with the altitude of the growing site, are discussed as potential causes for the observed variation.

    Full Text Available Quorum sensing signals are referred to as acylated homoserine lactones (AHL that are mainly found in Gram-negative bacteria. It implies the ability of certain bacteria of producing different AHL molecules. The bacteria Pseudomonas aureofaciens and Xenorhabdus nematophila were cultured in Luria-Bertani (LB10 media and CV026 was used as a reporter strain to detect the presence of AHLs produced by the cultured bacteria. In this study, the reporter strain has revealed the quorum sensing ability of P. aureofaciens and X. nematophila by producing the purple pigment violacein in the supply of external AHLs molecules. Thin layer chromatography (TLC bioassay having four controls was conducted to detect specific AHL molecule supplied by P. aureofaciens and X. nematophila. The specific AHL molecule was observed to be migrated according to their polarity on the TLC plate.

    Reynard (2004) defined a geomorphological landscape as a portion of the geomorphological context that is viewed, perceived, (and sometimes ex- ploited) by Man and, when perceived by humans and characterised by certain attributes, it may be considered a wider geomorphosite (Reynard and Panizza, 2005) or a complex of geomorphosites inside of which single geomorphosites can be individuated. Moreover, single geomorphosites belong to a landscape system that is dynamic, and thus the comprehension of a geomorphosite mechanism requires good observations, measurements and quantifications of processes (Reynard 2004). Since 1990s, interest on geomorphosite studies has increased, especially, due to their educational. The aim of this study is to present a preliminary inventory of the main geomorphosites that can be found along the Great Málaga Path (or Gran Senda de Málaga). This route, developed by the Government of Malaga Province, is a pioneer in Andalusia route incorporating the territorial and environmental range of an entire province, integrating it into a journey that stimulates interest in natural spaces. One of the main attractions is crossing most of the more important sites from the geomorphological point of view in the Province of Málaga. In this study, some of them are inventoried in order to highlight their importance and improve their knowledge from educational and touristic purposes. The methodology follows that proposed by the Spanish Geological and Mining Institute (IGME, 2014). References IGME, 2014.

    The discovery of well-preserved maar structures is important not only for studying the eruptive activity and formation of volcanoes, but also for paleoclimate research, since laminated maar lake sediments may contain very detailed archives of climate and environmental history. Maars are a singular type of volcanic structure generated by explosive phreatomagmatic eruptions as a result of interaction between rising magma and groundwater. This kind of structures are characterised by circular craters, often filled with water and/or lacustrine sediments and surrounded by a ring of pyroclastic deposits.Recently a borehole was drilled at the bottom of La Calderilla volcanic complex which penetrated about 8.7 m in its sedimentary sequence and paleobotanical study has supplied the first evidence of paleoenvironmental evolution during the Holocene on the Gran Canaria Island. This survey, however, did not penetrate into the substrate because the total thickness of the sedimentary fill was unknown. Since the age of formation of La Calderilla volcanic complex based on K/Ar dating is about 85,000 years (Upper Pleistocene), the possibility of its sedimentary fill extends beyond of the Holocene is extremely attractive, since, for example, there are few paleoenvironmental data regarding how much the last glaciation that affected the Canary Islands. In these circumstances, the knowledge of the total thickness of the lacustrine sediments is crucial to design a deeper borehole in the next future. Therefore, the subsurface characterisation provided by geophysics is essential for determining thickness and geometry of the sedimentary filling. Multielectrode ERT method was used to obtain five 2-D resistivity cross-sections into La Calderilla volcanic caldera.

    Full Text Available El sector sur del distrito pegmatítico Comechingones está constituido por pegmatitas graníticas zonadas, con morfologías mayormente lenticulares y mineralizaciones de Be, Nb-Ta y U, que se emplazan en milonitas de la faja de cizalla Guacha Corral. Los planos de la foliación milonítica de la roca de caja presentan variaciones significativas en su orientación definiendo un patrón anastomosado tanto a escala regional como a escala de afloramiento. Las pegmatitas son generalmente concordantes con esa foliación milonítica, aunque también se observaron pegmatitas discordantes. La deformación de la faja de cizalla Guacha Corral generó una fábrica planar definida por la orientación de feldespatos, cuarzo y moscovita que afecta especialmente las zonas intermedias de las pegmatitas. Las orientaciones de las lineaciones de estiramiento mineral son próximas a las medidas sobre los planos de foliación milonítica de la roca de caja. El análisis estructural indica un emplazamiento sincinemático de las pegmatitas durante el evento deformacional de carácter dúctil de la faja de cizalla Guacha Corral desarrollado bajo un régimen de cizalla compresional progresiva no coaxial, de carácter inverso, indicando transporte tectónico hacia el oeste. El patrón anastomosado de la foliación milonítica habría generado los espacios donde se emplazaron las pegmatitas, los cuales se enfriaron y cristalizaron de manera simultánea con una deformación. Las pegmatitas discordantes representan canales de ascenso del magma a través de fracturas extensionales T. Con la deformación progresiva, la mayoría de las pegmatitas originalmente discordantes sufrieron posteriormente cizallamiento y rotación hasta paralelizarse con la foliación milonítica regional, aflorando actualmente de manera subconcordante.

    Full Text Available Durante il periodo riproduttivo del 2000, 2001 e 2002, sono state effettuate delle osservazioni comportamentali su un campione (n=42 di maschi di stambecco (Capra ibex ibex riconoscibili individualmente, all?interno del Parco Nazionale del Gran Paradiso. Le osservazioni di ciascun maschio sono state distribuite uniformemente nel corso del periodo riproduttivo. In totale sono state effettuate 111 ore di osservazione nel 2000, 120 ore nel 2001 e 95 ore nel 2002. Sono state analizzate le diverse strategie riproduttive utilizzate e confrontati gli anni di studio. Marcate differenze individuali sono state rilevate nelle percentuali di tempo trascorso in corteggiamento ed in interazione aggressiva con altri maschi. Infatti, gli individui che trascorrono molto tempo in corteggiamento (media percentuale 25,6%, passano poco tempo ad interagire con altri maschi (media percentuale 1,1% e viceversa, maschi che trascorrono molto tempo in interazioni aggressive con altri maschi (media percentuale 14,8%, passano poco tempo in corteggiamento (media percentuale 2,4%. Gli spostamenti verso le femmine ed il numero di femmine corteggiate sono molto influenzati dalle condizioni ambientali. Infatti, con un?elevata presenza di neve al suolo, come nel caso del periodo riproduttivo 2000, i movimenti degli animali sono fortemente limitati ed i maschi trascorrono meno tempo in spostamenti da gruppi diversi di femmine e ne corteggiano quindi un numero minore. Nel corso degli anni sono state evidenziate differenze anche nelle diverse strategie riproduttive adottate: in assenza di neve, i maschi utilizzano sia i corteggiamenti statici (percentuale media 17,2%, effettuati dai maschi adulti per lungo tempo, che i corteggiamenti dinamici (percentuale media 1,0%, osservati nei maschi giovani in corsa. Al contrario, con un?elevata copertura nevosa (periodo riproduttivo 2000, non sono stati osservati corteggiamenti dinamici ed è aumentata la percentuale media del tempo
