    Full Text Available A study of the high vacuum brazing process of solid solution strengthened Hastelloy B2 nickel alloy has been done. A first stage of research has focused on the selection of the most appropriate brazing filler metal to the base material and vacuum furnace brazing process. The influence of welding parameters on joint microstructure constituents, relating the microstructure of the joint to its mechanical properties, has been evaluated. Two gaps of 50 and 200 micrometers, and two dwell times at brazing temperature of 10 and 90 minutes were studied. The braze joint mainly consists of the nickel rich matrix, nickel silicide and ternary compounds. Finally, the results of this study have shown the high bond strength for small gaps and increased dwell times of 90 minutes.Se realizó un estudio pormenorizado del proceso de soldeo fuerte en horno de alto vacío de la aleación base níquel Hastelloy B2 fortalecida por solución sólida. En una primera fase del trabajo se seleccionó el material de aporte acorde al material objeto de unión y a la fuente de calentamiento seleccionada. Posteriormente, se evaluó la influencia del gap (50 y 200 micrómetros y tiempo de permanencia a temperatura de soldeo (10 y 90 minutos sobre los microconstituyentes de la unión, relacionando la microestructura con las propiedades mecánicas de la junta. Los análisis metalográficos mostraron una unión constituida por una matriz rica en níquel, siliciuros de níquel y compuestos ternarios. Finalmente, los resultados de los ensayos mecánicos a esfuerzos cortantes mostraron una elevada resistencia para gaps de 50 micrómetros y tiempos de permanencia de 90 minutos.

La représentation d’une réalité géographique, sous couvert de procédés graphiques et techniques, ne révèlerait-elle pas un autre type de géographie ? La carte étant un outil de communication, les cartes des chemins de fer publiées à partir de 1853 aux Etats-Unis ne furent-elles pas un outil privilégié destiné à véhiculer de façon plus ou moins délibérée, sous couvert d’une représentation graphique matérialisée sous des formes diverses, un message à la fois d’information, de propagande ou de publicité à la gloire d’une réussite économique et politique ?In the second half of the 19th century, the United States transcontinental railroads stimulated an unprecedented cartographic activity. The representation of a geographical reality, hidden behind the mapping process, may lead to the disclosure of another and unexpected geography. Since any map is regarded as a tool of communication, the railroad maps, published in the United States since 1853, may be considered a privileged tool intended to convey a message of information, propaganda and advertising glorifying the economic and political success, hiding behind graphic representations featured in various forms.

    At the time of his election as President of the United States, Barack Obama declared that 'We will make it clear to the world that America is ready to lead to protect our environment'. The 2050 objective of cutting CO{sub 2} emissions by 80% compared to the 1990 level, as affirmed in the election campaign, will involve directing the market in accordance with a carbon price signal that includes the true cost of greenhouse gas emissions so as to establish a policy that is both effective and credible, i.e. likely to lead developing countries into the global effort. An emission allowance market, rather than a carbon tax, should therefore come into being. However, those who advocate the tax - more numerous in academic circles than among political decision-makers - are sharpening up their arguments. In particular, they identify the measures to be taken if we wish to attain an environmental objective and curb social inequalities. Similar arguments could serve as the basis for an international agreement that would strongly incite emerging countries to reduce their emissions while remaining equitable towards them. (author)

  1. UniNovo: a universal tool for de novo peptide sequencing.

    Science.gov (United States)

    Jeong, Kyowon; Kim, Sangtae; Pevzner, Pavel A

    2013-08-15

    Mass spectrometry (MS) instruments and experimental protocols are rapidly advancing, but de novo peptide sequencing algorithms to analyze tandem mass (MS/MS) spectra are lagging behind. Although existing de novo sequencing tools perform well on certain types of spectra [e.g. Collision Induced Dissociation (CID) spectra of tryptic peptides], their performance often deteriorates on other types of spectra, such as Electron Transfer Dissociation (ETD), Higher-energy Collisional Dissociation (HCD) spectra or spectra of non-tryptic digests. Thus, rather than developing a new algorithm for each type of spectra, we develop a universal de novo sequencing algorithm called UniNovo that works well for all types of spectra or even for spectral pairs (e.g. CID/ETD spectral pairs). UniNovo uses an improved scoring function that captures the dependences between different ion types, where such dependencies are learned automatically using a modified offset frequency function. The performance of UniNovo is compared with PepNovo+, PEAKS and pNovo using various types of spectra. The results show that the performance of UniNovo is superior to other tools for ETD spectra and superior or comparable with others for CID and HCD spectra. UniNovo also estimates the probability that each reported reconstruction is correct, using simple statistics that are readily obtained from a small training dataset. We demonstrate that the estimation is accurate for all tested types of spectra (including CID, HCD, ETD, CID/ETD and HCD/ETD spectra of trypsin, LysC or AspN digested peptides). UniNovo is implemented in JAVA and tested on Windows, Ubuntu and OS X machines. UniNovo is available at http://proteomics.ucsd.edu/Software/UniNovo.html along with the manual.

  2. Expanding the UniFrac Toolbox.

    Directory of Open Access Journals (Sweden)

    Ruth G Wong

    Full Text Available The UniFrac distance metric is often used to separate groups in microbiome analysis, but requires a constant sequencing depth to work properly. Here we demonstrate that unweighted UniFrac is highly sensitive to rarefaction instance and to sequencing depth in uniform data sets with no clear structure or separation between groups. We show that this arises because of subcompositional effects. We introduce information UniFrac and ratio UniFrac, two new weightings that are not as sensitive to rarefaction and allow greater separation of outliers than classic unweighted and weighted UniFrac. With this expansion of the UniFrac toolbox, we hope to empower researchers to extract more varied information from their data.

    Full Text Available The aim of this study was to evaluate the apical displacement produced by different rotary nickel-titanium instruments, testing the hypothesis that rotary systems with nickel-titanium instruments produce lower mean values of apical displacement than stainless steel hand instruments. A total of 100 maxillary permanent first molars were selected for the study. The mesiobuccal roots were sectioned at the top cervical third and embedded in blocks of self-curing resin. The specimens were randomly divided into 5 groups and the root canals were prepared using the following nickel-titanium instruments: Group 1 - Quantec system 2000 (Analytic Endodontics, Mexico; Group 2 - Pro-File T.0.04 (Dentsply/Maillefer, Switzerland; Group 3 - Pro-File Series 29 T.0.04 (Dentsply Tulsa, Switzerland; Group 4 - Pow-R T.0.02 (Moyco-Union Broach, USA. Specimens in Group 5 were prepared using stainless steel hand instruments Flexofile (Dentsply/Maillefer, Switzerland. All root canals were previously submitted to cervical preparation using Orifice Shaper instruments #1, 2, 3 and 4 (Dentsply/Maillefer, Switzerland. After odontometry, the remaining root canal was shaped employing increasingly larger instruments, so that the final instrument corresponded to Quantec #9, Pro-File Series 29 #6, and #35 for the other groups. Specimens in Groups 1 to 4 were prepared using an electric handpiece with 16:1 reduction at 350 rpm. The specimens in Group 5 were manually prepared. Apical displacement was measured and recorded by means of radiographic superimposition on a specific desk. Statistical analysis (ANOVA of the results revealed that all groups presented apical displacements.

    The Universal Protein Resource (UniProt, http://www.uniprot.org ) consortium is an initiative of the SIB Swiss Institute of Bioinformatics (SIB), the European Bioinformatics Institute (EBI) and the Protein Information Resource (PIR) to provide the scientific community with a central resource for protein sequences and functional information. The UniProt consortium maintains the UniProt KnowledgeBase (UniProtKB), updated every 4 weeks, and several supplementary databases including the UniProt Reference Clusters (UniRef) and the UniProt Archive (UniParc).The Swiss-Prot section of the UniProt KnowledgeBase (UniProtKB/Swiss-Prot) contains publicly available expertly manually annotated protein sequences obtained from a broad spectrum of organisms. Plant protein entries are produced in the frame of the Plant Proteome Annotation Program (PPAP), with an emphasis on characterized proteins of Arabidopsis thaliana and Oryza sativa. High level annotations provided by UniProtKB/Swiss-Prot are widely used to predict annotation of newly available proteins through automatic pipelines.The purpose of this chapter is to present a guided tour of a UniProtKB/Swiss-Prot entry. We will also present some of the tools and databases that are linked to each entry.

    The Swiss-Prot, TrEMBL, Protein Information Resource (PIR), and DNA Data Bank of Japan (DDBJ) protein database activities have united to form the Universal Protein Resource (UniProt) Consortium. UniProt presents three database layers: the UniProt Archive, the UniProt Knowledgebase (UniProtKB), and the UniProt Reference Clusters. The UniProtKB consists of two sections: UniProtKB/Swiss-Prot (fully manually curated entries) and UniProtKB/TrEMBL (automated annotation, classification and extensive cross-references). New releases are published fortnightly. A specific Plant Proteome Annotation Program (http://www.expasy.org/sprot/ppap/) was initiated to cope with the increasing amount of data produced by the complete sequencing of plant genomes. Through UniProt, our aim is to provide the scientific community with a single, centralized, authoritative resource for protein sequences and functional information that will allow the plant community to fully explore and utilize the wealth of information available for both plant and non-plant model organisms.

    2011-09-01

    Full Text Available Human interaction environments (HIE must be understood as any place where people carry out their daily life, including their work, family life, leisure and social life, interacting with technology to enhance or facilitate the experience. The integration of technology in these environments has been achieved in a disorderly and incompatible way, with devices operating in isolated islands with artificial edges delimited by the manufacturers. In this paper we are presenting the UniDA framework, an integral solution for the development of systems that require the integration and interoperation of devices and technologies in HIEs. It provides developers and installers with a uniform conceptual framework capable of modelling an HIE, together with a set of libraries, tools and devices to build distributed instrumentation networks with support for transparent integration of other technologies. A series of use case examples and a comparison to many of the existing technologies in the field has been included in order to show the benefits of using UniDA.

    Background The Emergency, Triage, Assessment and Treatment plus Admission care (ETAT+) course, a comprehensive advanced pediatric life support course, was introduced in Rwanda in 2010 to facilitate the achievement of the fourth Millennium Development Goal. The impact of the course on improving healthcare workers (HCWs) knowledge and practical skills related to providing emergency care to severely ill newborns and children in Rwanda has not been studied. Objective To evaluate the impact of the ETAT+ course on HCWs knowledge and practical skills, and to identify factors associated with greater improvement in knowledge and skills. Methods We used a one group, pre-post test study using data collected during ETAT+ course implementation from 2010 to 2013. The paired t-test was used to assess the effect of ETAT+ course on knowledge improvement in participating HCWs. Mixed effects linear and logistic regression models were fitted to explore factors associated with HCWs performance in ETAT+ course knowledge and practical skills assessments, while accounting for clustering of HCWs in hospitals. Results 374 HCWs were included in the analysis. On average, knowledge scores improved by 22.8/100 (95% confidence interval (CI) 20.5, 25.1). In adjusted models, bilingual (French & English) participants had a greater improvement in knowledge 7.3 (95% CI 4.3, 10.2) and higher odds of passing the practical skills assessment (adjusted odds ratio (aOR) = 2.60; 95% CI 1.25, 5.40) than those who were solely proficient in French. Participants who attended a course outside of their health facility had higher odds of passing the skills assessment (aOR = 2.11; 95% CI 1.01, 4.44) than those who attended one within their health facility. Conclusions The current study shows a positive impact of ETAT+ course on improving participants’ knowledge and skills related to managing emergency pediatric and neonatal care conditions.

    U-based intermetallic compound UNiGe absorbs hydrogen up to the stoichiometry UNiGeH{sub 1.2}. In analogy to other compounds with the TiNiSi-type of structure, the structure is modified into hexagonal. The zig-zag U-chains are stretched, the U-U spacing is largely enhanced and the ordering temperature increases up to 100 K. The ordered state has a spontaneous moment, but it is unlikely to be a simple ferromagnet. - Highlights: > UNiGe exhibits a variety of magnetic properties. > Hydrogenation modifies the crystal, electronic structure, and the magnetic properties. > Upon hydrogenation, the crystal symmetry of UNiGe increases from orthorhombic to hexagonal. > Magnetic ordering temperature of UNiGe (T{sub N}=44 K) is double in the hydride, possible second phase transition.

    2016-03-01

    Full Text Available Elution of nickel ions from alginate beads was studied in a temperature range of 2 to 80 °C and a sulfuric acid concentration between 0.005 to 2.5 g L−1. The elution mechanism was established by ion exchange between nickel and ions protons, obtaining a value of 93% elution at a temperature of 80 °C and a H2SO4 concentration of 0.25 g L−1. The influence of other acids on nickel elution was also studied. The nickel elution rate was significantly influenced by temperature and concentration of H2SO4. Elution kinetics of nickel ions was studied, and the 1-(1-α1/3=kappt model properly described the kinetics of this reaction. The dependence of nickel elution on the sulfuric acid concentration was of the order of 0.33. Moreover, the intrinsic rate constants were determined and an activation energy value of 54.5 kJ mol−1 was obtained for the temperature range studied. The results indicated that the nickel elution is a process controlled by chemical reactions.Se estudió la elución de iones de níquel desde esferas de alginato en un intervalo de temperaturas de 2 a 80 °C y una concentración de ácido sulfúrico entre 0,005 a 2,5 g L−1. El mecanismo de elución fue establecido por intercambio iónico entre protones e iones de níquel alcanzando valores de elución de 93% a una temperatura de 80 °C y concentración de H2SO4 de 0,25 g L−1. También se estudió la influencia de otros ácidos sobre la elución de níquel. La velocidad de elución de níquel fue significativamente influenciada por la temperatura y concentración de H2SO4. La cinética de elución de iones de níquel fue estudiada y el modelo 1-(1-α1/3=kappt describió muy bien la cinética de esta reacción.

    . In co-operation with private and governmental organizations, irradiated sea foods have been shipped across the United States in commercial carriers and evaluated for quality., Results are very encouraging and indicate that the process would be extremely valuable to industry. Irradiation of fish at sea shows promise as a means of increasing the landings of fresh fish. Preliminary findings indicate that it may be feasible to irradiate eviscerated groundfish at sea with levels less than 100 000 rad and then re-irradiate the fish ashore after filleting and packaging. (author) [French] Le memoire donne un apercu des recherches sur la radiopasteurisation des poissons, crustaces et mollusques aux Etats-Unis et expose les plans de commercialisation de ce procede. Les auteurs examinent: a) les etudes de laboratoire dans les universites et les instituts de recherche de l'Etat sur la qualite et les aspects microbiologiques des produits marins irradies; b) les essais d'irradiation des poissons a terre et en mer; c) l'autorisation officielle, aux Etats-Unis, de la vente des produits de la mer radiopasteurises et de l'utilisation de ce procede par l'industrie de la peche. Les etudes sur la qualite des produits indiquent que l'irradiation avec du cobalt-60 a des doses de 150 000 a 450 000 rad permet au moins de doubler la duree de conservation sous refrigeration de 16 especes de poissons et de crustaces ou mollusques, dont les principales especes vendues aux Etats-Unis a l'etat frais ou congele. La temperature d'emmagasinage, la qualite de la matiere premiere et la dose influent considerablement sur la qualite du produit et la duree de conservation; remballage presente une importance moindre.

    The Universal Protein Resource (UniProt) provides a central resource on protein sequences and functional annotation with three database components, each addressing a key need in protein bioinformatics. The UniProt Knowledgebase (UniProtKB), comprising the manually annotated UniProtKB/Swiss-Prot section and the automatically annotated UniProtKB/TrEMBL section, is the preeminent storehouse of protein annotation. The extensive cross-references, functional and feature annotations and literature-based evidence attribution enable scientists to analyse proteins and query across databases. The UniProt Reference Clusters (UniRef) speed similarity searches via sequence space compression by merging sequences that are 100% (UniRef100), 90% (UniRef90) or 50% (UniRef50) identical. Finally, the UniProt Archive (UniParc) stores all publicly available protein sequences, containing the history of sequence data with links to the source databases. UniProt databases continue to grow in size and in availability of information. Recent and upcoming changes to database contents, formats, controlled vocabularies and services are described. New download availability includes all major releases of UniProtKB, sequence collections by taxonomic division and complete proteomes. A bibliography mapping service has been added, and an ID mapping service will be available soon. UniProt databases can be accessed online at http://www.uniprot.org or downloaded at ftp://ftp.uniprot.org/pub/databases/.

    Full Text Available There is a need for human development especially for the less privileged Muslims in the state due to financial constraints, unemployment, insufficient and inadequate financial support. The study discussed and analyzed the structured interviews conducted on factors influencing UniSZA’s staff cash waqf and its possible impact on the socio-economic development of Terengganu. The total number of 150 respondents participated in the first instrumental validation section where 150 questionnaires were distributed and collected. 150 questionnaires were distributed between February and June 2015 to the UniSZA’s staff such as lecturer, senior, and junior staff in the university. The instrument was divided into four sections. Firstly, the respondent’s profile, (15 items. Secondly, factors influencing UniSZA’s staff cash waqf contribution (15 items. Thirdly, promoting economic and human development (15 items. Fourthly, the importance to the society’s development (15 items. The content validity of the questionnaire would be evaluated by the researchers to improve the questionnaire. The participants were selected from lecturers, administrative staff, and students to discover the breadth and extent of the needs for UniZSA’s staff cash waqf contribution to the state. Waqf provides human relief, dignity, financial support, and social needs to reduce poverty in the society. The research is based on the hypothesis that UniSZA’s staff cash waqf can have a positive social and economic impact in Terengganu. The objective of this study is to examine the viability of a UniSZA staff cash waqf and how cash waqf can be utilized to develop Terengganu economically and socially for the interest of the needy Muslims in Terengganu. The study applies the quantitative and qualitative methods throughout the discussion and analysis. Human development includes the creation of employment, micro-finance, transaction, farming, soft loans, and other lawful lucrative

    The UniProt knowledgebase, UniProtKB, is the main product of the UniProt consortium. It consists of two sections, UniProtKB/Swiss-Prot, the manually curated section, and UniProtKB/TrEMBL, the computer translation of the EMBL/GenBank/DDBJ nucleotide sequence database. Taken together, these two sections cover all the proteins characterized or inferred from all publicly available nucleotide sequences. The Plant Proteome Annotation Program (PPAP) of UniProtKB/Swiss-Prot focuses on the manual annotation of plant-specific proteins and protein families. Our major effort is currently directed towards the two model plants Arabidopsis thaliana and Oryza sativa. In UniProtKB/Swiss-Prot, redundancy is minimized by merging all data from different sources in a single entry. The proposed protein sequence is frequently modified after comparison with ESTs, full length transcripts or homologous proteins from other species. The information present in manually curated entries allows the reconstruction of all described isoforms. The annotation also includes proteomics data such as PTM and protein identification MS experimental results. UniProtKB and the other products of the UniProt consortium are accessible online at www.uniprot.org.

  16. Unconventional superconductivity of the heavy fermion compound UNi2Al3

    2008-01-01

    The heavy fermion compound UNi 2 Al 3 exhibits the coexistence of superconductivity and magnetic order at low temperatures, stimulating speculations about possible exotic Cooper-pairing interaction in this superconductor. However, the preparation of good quality bulk single crystals of UNi 2 Al 3 has proven to be a non-trivial task due to metallurgical problems, which result in the formation of an UAl 2 impurity phase and hence a strongly reduced sample purity. The present work concentrates on the preparation, characterization and electronic properties investigation of UNi 2 Al 3 single crystalline thin film samples. The preparation of thin films was accomplished in a molecular beam epitaxy (MBE) system. (100)-oriented epitaxial thin films of UNi 2 Al 3 were grown on single crystalline YAlO 3 substrates cut in (010)- or (112)-direction. The high crystallographic quality of the samples was proved by several characterisation methods, such as X-ray analysis, RHEED and TEM. To study the magnetic structure of epitaxial thin films resonant magnetic X-ray scattering was employed. The magnetic order of thin the film samples, the formation of magnetic domains with different moment directions, and the magnetic correlation length were discussed. The electronic properties of the UNi 2 Al 3 thin films in the normal and superconducting states were investigated by means of transport measurements. A pronounced anisotropy of the temperature dependent resistivity ρ(T) was observed. Moreover, it was found that the temperature of the resistive superconducting transition depends on the current direction, providing evidence for multiband superconductivity in UNi 2 Al 3 . The initial slope of the upper critical field H' c2 (T) of the thin film samples suggests an unconventional spin-singlet superconducting state, as opposed to bulk single crystal data. To probe the superconducting gap of UNi 2 Al 3 directly by means of tunnelling spectroscopy many planar junctions of different design

    Bui, Duong Minh; Chen, Shi-Lin; Lien, Keng-Yu; Jiang, Jheng-Lun

    2016-04-01

    This paper presents three main configurations of uni-grounded low-voltage AC microgrids. Transient situations of a uni-grounded low-voltage (LV) AC microgrid (MG) are simulated through various fault tests and operation transition tests between grid-connected and islanded modes. Based on transient simulation results, available fault protection methods are proposed for main and back-up protection of a uni-grounded AC microgrid. In addition, concept of a generalised fault protection structure of uni-grounded LVAC MGs is mentioned in the paper. As a result, main contributions of the paper are: (i) definition of different uni-grounded LVAC MG configurations; (ii) analysing transient responses of a uni-grounded LVAC microgrid through line-to-line faults, line-to-ground faults, three-phase faults and a microgrid operation transition test, (iii) proposing available fault protection methods for uni-grounded microgrids, such as: non-directional or directional overcurrent protection, under/over voltage protection, differential current protection, voltage-restrained overcurrent protection, and other fault protection principles not based on phase currents and voltages (e.g. total harmonic distortion detection of currents and voltages, using sequence components of current and voltage, 3I0 or 3V0 components), and (iv) developing a generalised fault protection structure with six individual protection zones to be suitable for different uni-grounded AC MG configurations.

    The UniPrime2 web server is a publicly available online resource which automatically designs large sets of universal primers when given a gene reference ID or Fasta sequence input by a user. UniPrime2 works by automatically retrieving and aligning homologous sequences from GenBank, identifying regions of conservation within the alignment, and generating suitable primers that can be used to amplify variable genomic regions. In essence, UniPrime2 is a suite of publicly available software packages (Blastn, T-Coffee, GramAlign, Primer3), which reduces the laborious process of primer design, by integrating these programs into a single software pipeline. Hence, UniPrime2 differs from previous primer design web services in that all steps are automated, linked, saved and phylogenetically delimited, only requiring a single user-defined gene reference ID or input sequence. We provide an overview of the web service and wet-laboratory validation of the primers generated. The system is freely accessible at: http://uniprime.batlab.eu.

    Lignereux, Bastien; Nicolazo de Barmon, Marie-Astrid

    2017-07-01

    The National Association of energy retailer operators (ANODE) brought proceedings to the Conseil d'Etat arguing that the decree of 16 May 2013 regarding regulated tariffs for the supply of natural gas was 'ultra vires'. The ANODE submitted that this tariff regulation breached European Union Law. Applying the findings of the preliminary ruling of 7 September 2016 given in this matter by the European Court of Justice, the Conseil d'Etat, in today's decision, annulled the decree of 16 May 2013 on the grounds that the imposition of a natural gas tariff regulation infringed European Union Law. In light of the great uncertainty that would affect contracts signed by millions of consumers as a result of such an annulment, and with regard to the necessity to prevent the legal insecurity that would ensue, the Conseil d'Etat has judged, exceptionally, that the past effects of this decree, which ceased to apply on 1 January 2016, must nevertheless be regarded as irrevocable

    Directory of Open Access Journals (Sweden)

    Michel eSchneider

    2012-12-01

    Full Text Available The UniProt knowledgebase (UniProtKB provides a single, centralized, authoritative resource for protein sequences and functional information. The majority of its records is based on automatic translation of coding sequences (CDS provided by submitters at the time of initial deposition to the nucleotide sequence databases (INSDC. More and more frequently, only the raw sequence of a complete genome is deposited to the nucleotide sequence databases and the gene model predictions and annotations are kept in separate, specialized model organism databases (MODs. In order to be able to provide the complete proteome of model organisms, UniProtKB had to implement pipelines for import of protein sequences from Ensembl and EnsemblGenomes.A single genome can be the target of several unrelated sequencing projects and the final assembly and gene model predictions may diverge quite significantly. In addition, several cultivars of the same species are often sequenced -1001 Arabidopsis cultivars are currently under way- and the resulting proteomes are far from being identical. Therefore, one challenge for UniProtKB is to store and organize these data in a convenient way and to clearly defined reference proteomes that should be made available to users. Manual annotation is one of the landmarks of the Swiss-Prot section of UniProtKB. Besides adding functional annotation, curators are checking, and often correcting, gene model predictions. For plants, this task is limited to Arabidopsis thaliana and Oryza sativa subsp japonica. Proteomics data providing experimental evidences confirming the existence of proteins or identifying sequence features such as post translational modifications are also imported into UniProtKB records and the knowledgebase is cross-referenced to numerous proteomics resources.

  3. The unique sound of the uni-vibe pedal: Part II. Transient behaviour

    Hahlweg, Cornelius F.; Rothe, Hendrik

    2013-09-01

    The Uni-Vibe is an effect pedal mostly used by electric guitar players. It is based on an opto-electronically controlled all-pass chain. In last year's paper on the subject an idealized system model was derived, which lead to deeper discussion of the musical consequences of the effect in terms of harmonic analysis of single tones and chords in clean and distorted mode. As a direct continuation the present paper deals with the transient behaviour of the device. The transient response is essential for understanding the special sound character, the reaction on picking techniques and the interaction with certain instruments. Therefore the system model is expanded and the pulse response of the idealized time invariant system is derived.

    This report is based on information gathered in the course of a trip to the United States, in November and December 1958 which consisted chiefly of visits to the main biological and medical research laboratories and discussions with the heads of these establishments. A description is given of the general organisation of the Atomic Energy Commission's Division of Biology and Medicine, and of the distribution of responsibility for radiation protection work and for biological, medical and agricultural research amongst the various Services attached to it; this is followed by a more detailed account of the activities carried on in this field at the great national laboratories. Finally, the systems of collaboration set up with external research organisations in the form of research contracts are examined, together with the substantial help provided by the A.E.C. for biological, medical and agricultural research in general, owing to a systematic policy of subsidising the distribution of radioisotopes for this purpose.

    Full Text Available The Accord du Papillon started the Belgium Sexième réforme de l’Etat. After a long institutional crisis, an agreement between the major parties seemed the best way to ensure a stable government to the country and to enhance a new season of constitutional reforms. It consisted, so far, in two sessions (2012 and 2014 that brought to the adoption of both legislative and constitutional acts. Two reforms appear crucial. First and foremost, the Sexième réforme de l’Etat set forth the criteria to divide the Bruxelles-Hal Vilvorde district. Furthermore, it determined the Senate reform. Nonetheless, in the past months, the reformist enthusiasm decreased gradually, but probably this is a temporary situation: in Belgium, things are more complicated than they seem, so it is hard to have the last word.

  8. MetaUniDec: High-Throughput Deconvolution of Native Mass Spectra

    The expansion of native mass spectrometry (MS) methods for both academic and industrial applications has created a substantial need for analysis of large native MS datasets. Existing software tools are poorly suited for high-throughput deconvolution of native electrospray mass spectra from intact proteins and protein complexes. The UniDec Bayesian deconvolution algorithm is uniquely well suited for high-throughput analysis due to its speed and robustness but was previously tailored towards individual spectra. Here, we optimized UniDec for deconvolution, analysis, and visualization of large data sets. This new module, MetaUniDec, centers around a hierarchical data format 5 (HDF5) format for storing datasets that significantly improves speed, portability, and file size. It also includes code optimizations to improve speed and a new graphical user interface for visualization, interaction, and analysis of data. To demonstrate the utility of MetaUniDec, we applied the software to analyze automated collision voltage ramps with a small bacterial heme protein and large lipoprotein nanodiscs. Upon increasing collisional activation, bacterial heme-nitric oxide/oxygen binding (H-NOX) protein shows a discrete loss of bound heme, and nanodiscs show a continuous loss of lipids and charge. By using MetaUniDec to track changes in peak area or mass as a function of collision voltage, we explore the energetic profile of collisional activation in an ultra-high mass range Orbitrap mass spectrometer.

  10. Unconventional superconductivity of the heavy fermion compound UNi{sub 2}Al{sub 3}

    Energy Technology Data Exchange (ETDEWEB)

    Zakharov, Andrey

    2008-07-01

    The heavy fermion compound UNi{sub 2}Al{sub 3} exhibits the coexistence of superconductivity and magnetic order at low temperatures, stimulating speculations about possible exotic Cooper-pairing interaction in this superconductor. However, the preparation of good quality bulk single crystals of UNi{sub 2}Al{sub 3} has proven to be a non-trivial task due to metallurgical problems, which result in the formation of an UAl{sub 2} impurity phase and hence a strongly reduced sample purity. The present work concentrates on the preparation, characterization and electronic properties investigation of UNi{sub 2}Al{sub 3} single crystalline thin film samples. The preparation of thin films was accomplished in a molecular beam epitaxy (MBE) system. (100)-oriented epitaxial thin films of UNi{sub 2}Al{sub 3} were grown on single crystalline YAlO{sub 3} substrates cut in (010)- or (112)-direction. The high crystallographic quality of the samples was proved by several characterisation methods, such as X-ray analysis, RHEED and TEM. To study the magnetic structure of epitaxial thin films resonant magnetic X-ray scattering was employed. The magnetic order of thin the film samples, the formation of magnetic domains with different moment directions, and the magnetic correlation length were discussed. The electronic properties of the UNi{sub 2}Al{sub 3} thin films in the normal and superconducting states were investigated by means of transport measurements. A pronounced anisotropy of the temperature dependent resistivity {rho}(T) was observed. Moreover, it was found that the temperature of the resistive superconducting transition depends on the current direction, providing evidence for multiband superconductivity in UNi{sub 2}Al{sub 3}. The initial slope of the upper critical field H'{sub c2}(T) of the thin film samples suggests an unconventional spin-singlet superconducting state, as opposed to bulk single crystal data.

    Hargreaves, J. E.

    2012-09-01

    UniBoard is a generic high-performance computing platform for radio astronomy, developed as a Joint Research Activity in the RadioNet FP7 Programme. The hardware comprises eight Altera Stratix IV Field Programmable Gate Arrays (FPGAs) interconnected by a high speed transceiver mesh. Each FPGA is connected to two DDR3 memory modules and three external 10Gbps ports. In addition, a total of 128 low voltage differential input lines permit connection to external ADC cards. The DSP capability of the board exceeds 644E9 complex multiply-accumulate operations per second. The first production run of eight boards was distributed to partners in The Netherlands, France, Italy, UK, China and Korea in May 2011, with a further production runs completed in December 2011 and early 2012. The function of the board is determined by the firmware loaded into its FPGAs. Current applications include beamformers, correlators, digital receivers, RFI mitigation for pulsar astronomy, and pulsar gating and search machines The new UniBoard based correlator for the European VLBI network (EVN) uses an FX architecture with half the resources of the board devoted to station based processing: delay and phase correction and channelization, and half to the correlation function. A single UniBoard can process a 64MHz band from 32 stations, 2 polarizations, sampled at 8 bit. Adding more UniBoards can expand the total bandwidth of the correlator. The design is able to process both prerecorded and real time (eVLBI) data.

    Full Text Available Whole genome sequences of various primates have been released due to advanced DNA-sequencing technology. A combination of computational data mining and the polymerase chain reaction (PCR assay to validate the data is an excellent method for conducting comparative genomics. Thus, designing primers for PCR is an essential procedure for a comparative analysis of primate genomes. Here, we developed and introduced UniPrimer for use in those studies. UniPrimer is a web-based tool that designs PCR- and DNA-sequencing primers. It compares the sequences from six different primates (human, chimpanzee, gorilla, orangutan, gibbon, and rhesus macaque and designs primers on the conserved region across species. UniPrimer is linked to RepeatMasker, Primer3Plus, and OligoCalc softwares to produce primers with high accuracy and UCSC In-Silico PCR to confirm whether the designed primers work. To test the performance of UniPrimer, we designed primers on sample sequences using UniPrimer and manually designed primers for the same sequences. The comparison of the two processes showed that UniPrimer was more effective than manual work in terms of saving time and reducing errors.

    Full Text Available Transient situations of a uni-grounded low-voltage AC microgrid are simulated in this paper, which include different fault tests and operation transition test between the grid-connected and islanded modes of the uni-grounded microgrid. Based on transient simulation results, available fault protection methods are proposed for the main and back-up protection of a uni-grounded AC microgrid. Main contributions of this paper are (i analysing transient responses of a typically uni-grounded lowvoltage AC microgrid from line-to-line, single line-to-ground, three-phase faults and a microgrid operation transition test; and (ii proposing available fault protection methods for uni-grounded AC microgrids, such as non-directional/directional overcurrent protection solutions, under/over voltage protection solutions, differential protection, voltage-restrained overcurrent protection, and other protection principles not based on high fault currents (e.g. total harmonic distortion detection of phase currents and voltages, or protection methods using symmetrical sequence components of current and voltage.

    The resistivity and Hall coefficient of single-crystal UNi 2 Si 2 have been studied in detail for the temperature range 4.2-300 K. The resistivity of UNi 2 Si 2 is largely due to magnetic scattering and the phonon scattering contribution is estimated to be about 14% at room temperature. At low temperatures, the resistivity can be described by a gapped spin-wave model plus a T 2 term. The temperature dependence of the Hall coefficient is accounted for by a theoretical model invoking skew scattering of conduction electrons by localized magnetic moments. Among the three magnetic phase transition temperatures, the two lower ones are found to be magnetic field dependent and shift with the field applied along the tetragonal c axis. Using the resistivity measurement in an applied magnetic field, a field-temperature phase diagram of UNi 2 Si 2 is presented. (author)

    Micro-satellite missions, thanks to the miniaturization process of electronic components, now have a broader range of applications. Gauss Group at School of Aerospace Engineering has been a pioneer in educational micro-satellites, namely with UNISAT and EDUSAT missions. Moreover it has been long involved in space debris related studies, such as optical observations as well as mitigation. A new project is under development for a compact digital imaging system. The purpose will be in situ observation of space debris on board Unisat-5 micro-satellite. One of the key elements of observing on orbit is that many atmospheric phenomena would be avoided, such as diffraction and EM absorption. Hence images would gain more contrast and solar spectral irradiance would be higher for the whole visible spectrum Earlier limitations of power and instrument size prevented the inclusion of these payloads in educational satellite missions. The system is composed of an optical tube, a camera, C band and S band transceivers and two antennas. The system is independent from the rest of the spacecraft. The optical tube is a Schmidt-Cassegrain reflector, and the magnitude limit is 13. The camera is equipped with a panchromatic 5Mpix sensor, capable of direct video streaming, as well as local storage of recorded images. The transceivers operate on ISM 2.4GHz and 5 GHz Wi-Fi bands, and they provide stand-alone communication capabilities to the payload, and Unisat-5 OBDH can switch between the two. Both transceivers are connected to their respective custom-designed patch antenna. The ground segment is constituted of a high gain antenna dish, which will use the same transceiver on board the spacecraft as the feed, in order to establish a TCP/IP wireless link. Every component of this system is a consumer grade product. Therefore price reduction of cutting edge imaging technology now allows the use of professional instruments, that combined with the new wireless technology developed for

    UNiGe undergoes two magnetic transitions in zero field. Here, the magnetic diagrams of UNiGe for B parallel b and B parallel c are reported. We performed temperatures scans of the magnetization in static magnetic fields up to 19.5T applied along the b and c axes. For both orientations 3 magnetic phases have been identified in the B-T diagrams. We confirmed the previously reported phase boundaries for B parallel c, and in addition we determined the location of the phase boundaries for B parallel b. We discuss a possible relationship of the two zero-field antiferromagnetic phases (commensurate: T<42K; incommensurate: 42K< T<50K) and the field-induced phase, which, at low temperatures, occurs between 18 and 25T or 4 and 10T for B parallel b or B parallel c, respectively. Finally, we discuss the field dependence of the electronic contribution γ to the specific heat for B parallel c up to 17.5T, and we find that its field dependence is similar to the one found in more itinerant uranium compounds

    Measurements of the electrical resistivity, Hall coefficient and thermoelectric power have been carried out for silver telluride over a large temperature range including both solid and liquid states. The analysis of the experimental data shows that in the solid state the transport properties are governed by an ambipolar process with an electron mobility much higher than the hole mobility ({mu}{sub n} = 10*{mu}{sub p}). It is found that the temperature dependence of the electron mobility can be represented by a T{sup -3} law. Deviations from the stoichiometric composition Ag{sub 2}Te have been studied. For all specimens, melting is accompanied by discontinuous variations in the transport properties. Above the melting point, the magnitude of the measured parameters and their temperature dependence show that liquid silver telluride behaves as a semiconductor. The contribution of Ag{sup +} ions to transport phenomena is suggested to account for the behaviour of the electrical properties. Experimental data have been analysed in terms of conventional theories.

    Core and valence band spectra of U metal and the intermetallic compounds UNi 5 , UCu 5 and UNisub(0.5)Cusub(4.5) have been measured by X-ray excited photoelectron spectroscopy (XPS). The data indicate that in UNi 5 the configuration is 5f 3 , and in UCu 5 and UNisub(0.5)Cusub(4.5) a mixed valence configuration with fewer 5f electrons than in UNi 5 is present. (author)

    We report on a thermal-expansion (TE) and magnetostriction (MS) study of the antiferromagnet UNiAl at temperatures 2-90 K and in magnetic fields up to 16.5 T applied along the c-axis. The TE along the c-axis (in 0 T) exhibits a broad valley centered around 35 K. This anomaly is nearly removed in 16.5 T. For T≤7 K a sharp metamagnetic transition (MT) observed in UNiAl at 11.4 T and it is accompanied by abrupt MS effects of +1.3x10 -4 and -1.8x10 -4 along the a- and c-axis, respectively. In fields above the MT a negligible additional negative MS is induced along c-axis whereas the a-axis and consequently the volume expand considerably, which indicates a field-induced enhancement of the U magnetic moment. T>7 K, the MT becomes gradually smeared out but a non-negligible MS is observed even for T>T N . In the light of these results the TE anomaly measured in zero field may be attributed to AF that survives at temperatures far above T N

    This paper presents the analysis and evaluation of the chassis design for University Automotive Racing Team No. 4 (UniART4) car based on finite element analysis. The existing UniART4 car chassis was measured and modelled geometrically using Solidwork before analysed in FEA software (ANSYS). Four types of static structural analysis were used to predict the chassis design capability under four different loading conditions; vertical bending, lateral bending, lateral torsion and horizontal lozenging. The results showed the chassis subjected to the highest stress and strain under horizontal lozenging, whereas the minimum stress and strain response was obtained under lateral bending. The present analysis result could provide valuable information in predicting the sustainability of the current UniART car chassis design.

    The thermal expansion of single crystalline UNiGa has been measured along the crystallographic axes (a and c) under pressures up to 1.1 GPa. The linear thermal expansion both in the paramagnetic and antiferromagnetic ranges is strongly anisotropic. The antiferromagnetic ordering is accompanied by considerable (10 -4 ) linear spontaneous magnetostrictions (along the a- and c-axis) of different signs (-0.8 x 10 -4 and 1.8 x 10 -4 ). The mutual compensation of these two effects causes the volume effect to be rather small (∝10 -5 ). Two of the four magnetic phase transitions in UNiGa indicated by the expansion anomalies under ambient pressure are suppressed by pressures above 0.5 GPa. Results of our experiments allow to construct a pressure-temperature (p-T) magnetic phase diagram. (orig.)

    After, a description of the technique used, a qualitative examination is made of the influence of the temperature on the {nu}{sub OH}(3,400 cm{sup -1}) and {nu}{sub OD} (2,500 cm{sup -1}) valence bands of HDO in the liquid state and then during the passage to the solid state. Quantitative examination with two cells of different thickness makes it possible to define the influence of temperature on the residual absorption of the pure liquid (D{sub 2}O or H{sub 2}O and on the valency bands ({nu}{sub OH} and {nu}{sub OD} respectively). It is found that a similar change occurs in the two bands but that the changes in the background are very different. During the passage from the liquid to the solid state the shape of the bands varies considerably but little change occurs in the total intensity. It has been possible to express these results in a simple form which is directly applicable to analytical problems. (authors) [French] Apres un rappel de la technique utilisee, on examine qualitativement l'influence de la temperature sur les bandes de valence {nu}{sub OH} (3400 cm{sup -1}) et {nu}{sub OD} (2500 cm{sup -1}) de HDO a l'etat liquide puis le passage a l'etat solide. L'examen quantitatif, avec deux cuves d'epaisseurs differentes, permet de preciser l'influence de la temperature sur l'absorption residuelle du liquide pur (D{sub 2}O ou H{sub 2}O) et sur les bandes de valence ( {nu}{sub OH} et {nu}{sub OD} respectivement). On constate une evolution parallele de ces bandes mais un comportement tres different du fond continu.

    2017-11-01

    Full Text Available Technological developments are pushing for new solutions based upon massive integration of renewable electricity generation in networks already facing many challenges. This paper presents a novel approach to managing the energy transfer towards prosumers making use of smart management of local energy storage. The proposed design (including storage dimensioning is based on several operating scenarios in which the prosumer might operate as: (i a “load only” entity (from a grid perspective, thus exhibiting investment resiliency against regulatory changes and high energy efficiency; or (ii a prosumer, in case regulatory opportunistic profit might be available. This can be realized within a newly proposed Uni-directional Resilient Consumer (UniRCon architecture. The major aim of the proposed architecture is to achieve optimal self-consumption while avoiding curtailment even in a changing regulatory environment like, for example, the total lack of incentives for generation based on renewable energy sources (RES. One of the major advantages of the proposed architecture consists in the adaptability to changes in the regulatory and market environment. The term resilience is used with multiple meanings: (a the prosumer’s financial resilience against regulatory changes when investment calculations assume no-grid injections; (b the prosumer’s technical resilience, with electrical design based on standalone operation; (c the resilience of clusters of interconnected end-user installations with enabled community-level electricity exchange, independent of the existing main grid supply; (d the contribution to grid resilience, by enabling AC microgrid (MG operation in island mode when large portions of the grid are formed by clusters of UniRCon prosumers (the ease of islanding segmentation of the local grid in case of emergencies. For proof of concept, three use-cases are detailed: (i photovoltaic (PV installations connected behind the meter; (ii PV and

    Condensation-induced water hammers belong to the most serious and complex pressure surges. Experimental data from literature are scanty, incomplete, not public or simply missing. A new test facility at the UniBw (University of the German Armed Forces) was constructed to perform own experiments within a research alliance. This new test facility uses a complete new approach. In contrast to other test stations, the UniBw water hammer test facility is a closed system. This leads on the one hand to a more complex handling with respect of conducting experiments but on the other hand also to a more realistic characterization of thermo-hydraulic phenomena which can occur in a power plant. The first results of a measured condensation-induced water hammer are presented. (orig.)

    Full Text Available Dans son livre Cinq cents ans d’imprimerie, l’historien S. H. Steinberg plaide pour l’élimination des caractères non-latin et cite le gaélique d’Irlande comme l’exemple même d’une typographie devenue désuète. Si cette critique peut être considérée comme malveillante par certains commentateurs, elle n’en fournit pas moins un cadre utile à une étude des caractères typographiques gaéliques et de leur signification.Comme Steinberg, nous pouvons envisager la typographie gaélique de trois manières.Premièrement, loin d’avoir été développées en Irlande, les fontes gaéliques furent d’abord conçues et fabriquées en Angleterre. Des formes plus tardives apparurent en Belgique, France, Italie, Australie et aux Etats-Unis. Ont-elles une identité essentiellement irlandaise ?Deuxièmement, la création de ces fontes découla, à l’origine, de la politique religieuse d’Elizabeth Ière. Elles devinrent plus tard un instrument de la Contre-réforme et plus tard encore du nationalisme irlandais. En dehors de son utilisation à des fins de propagande, la typographie gaélique a-t-elle jamais véritablement existé ?Enfin, les inventeurs des caractères typographiques gaéliques se sont toujours montrés hostiles à toute évolution susceptible de parvenir à une plus grande lisibilité. La forme de chaque caractère répond davantage à un critère d’authenticité visuelle qu’à une quelconque notion d’efficacité.  Comment l’irlandité est-elle ainsi véhiculée par la typographie ?

  16. Liquid state behaviour of semi-conducting materials; Comportement a l'etat liquide des materiaux semiconducteurs

    Vandevyver, M. [Commissariat a l' Energie Atomique, Saclay (France). Centre d' Etudes Nucleaires

    1968-07-01

    This work is a review of the present state of knowledge concerning the behaviour in the liquid state of materials having semi-conducting properties in the solid state. In the case of many materials it is observed that a 'short-distance order' persists (with modifications) at temperatures above the melting point; this phenomenon is responsible for the semi-conducting properties of certain liquids. A decrease in the mobility of the carriers is generally observed on fusion, whereas the width of the forbidden zone increases: {delta}E{sub g} = {delta}E{sub g1} + {delta}E{sub g2}; {delta}E{sub g1} which is related to the expansion of the crystal is usually positive whereas {delta}E{sub g2} which is related to a change in the short-distance order is negative. According to the relative importance of these two phenomena, {delta}E{sub g} is either positive or negative, involving an increase or a decrease in the semiconducting nature of the material at its melting point. Various examples are presented, in particular that of selenium-tellurium solutions. The experimental study of the electrical properties of liquids comes up against major difficulties (the Hall effect in particular). It is shown nevertheless that the theoretical studies explain semi-quantitatively the known experimental results. (author) [French] Cette etude fait le point sur l'etat actuel des connaissances relatives au comportement a l'etat liquide des materiaux presentant a l'etat solide des proprietes semiconductrices. Dans de nombreux materiaux on observe la persistance (avec modification), d'un 'ordre a courte distance' a des temperatures superieures a celles de la fusion; ceci est a l'origine des proprietes semiconductrices de certains liquides. A la fusion on observe generalement une diminution de la mobilite des porteurs tandis que la largeur de la bande interdite subit un accroissement: {delta}E{sub g} = {delta}E{sub g1} + {delta}E{sub g2}; {delta}E{sub g1

    Full Text Available El objetivo de este trabajo es analizar la movilidad de la distribución de la renta por habitante a escala regional en la Unión Europea durante el período 1977-1996, con el fin de aportar elementos complementarios sobre la naturaleza de la desigualdad interregional. Para ello se utiliza una metodología novedosa basada en el cálculo de una serie de indicadores empleados habitualmente en el estudio dinámico de la distribución interpersonal de la renta. Los resultados obtenidos sugieren que el nivel de movilidad intradistribucional es relativamente bajo. Asimismo, la evidencia empírica aportada muestra la existencia de una tendencia hacia la reducción de la movilidad regional a lo largo del período analizado que ha coincidido en el tiempo con el mantenimiento de la desigualdad interregional en la Unión Europea.

Se empleó un diseño experimental factorial multinivel aleatorio en el que la densidad de la corriente y el tiempo de reacción fueron evaluados en tres niveles, mientras que la separación entre electrodos fue analizada en dos niveles. La electrocoagulación se llevó a cabo en un reactor batch usando electrodos de hierro con arreglo monopolar. Fueron utilizadas las técnicas analíticas de digestión ácida, absorción atómica de llama de aire-acetileno y reflujo cerradocolorimétrico (micro DQO para determinar el contenido de los contaminantes. Las condiciones con que se obtuvo la mayor descontaminación del agua analizada fue con la densidad de corriente aplicada: 1,04 A/dm² y tiempo de operación: 17 minutos; con estas variables se observó que la separación electródica no influyó. Los resultados indican que la electrocoagulación podría ser usada para disminuir el níquel y la materia orgánica (DQO presentes en las aguas residuales de la industria automotriz.

    Full Text Available O debate sobre os direitos das uniões homoafetivas constitui um dos tópicos mais controversos do direito constitucional. Como se sabe, a união homoafetiva não foi reconhecida expressamente no § 3º do artigo 226 da CF, inexistindo norma específica. O presente artigo pretende investigar a posição de ministros do STF em relação ao tema das uniões homoafetivas, em conexão com as filosofias do reconhecimento propostas por Axel Honneth e Nancy Fraser. Nesse sentido, os fundamentos filosóficos das teorias do reconhecimento podem ser um instrumental teórico fundamental para a compreensão de determinadas formas de ativismo judicial que objetivam a proteção de minorias estigmatizadas cujas pretensões normativas são desconsideradas pelo processo político. Pretendemos demonstrar que o paradigma da autorrealização proposto por Honneth é impreciso e incapaz de legitimar formas de ativismo judicial voltadas para a proteção dos direitos das uniões homoafetivas.The homosexual union rights are debated as one of the most controversial topics of Constitutional Law. It is known that the homosexual union was not explicitly recognized by the article 226 § 3º from FC, as there is no specific regulation for this subject. This paper intends to investigate STF ministers' position in relation to homosexual union according to Axel Honneth and Nancy Fraser philosophies of recognition. In this sense, the philosophical basis from recognition theories may be a theoretical instrument to comprehend some forms of judicial activism which aims are to protect stigmatized minorities whose regulatory intentions are disregarded by the political process. We intend to demonstrate that the Honneth's paradigm of achievement is imprecise and can't legitimate forms of judicial activism aimed to protect the rights of homosexual unions.

Es aquí donde ya es cada vez más difícil hacer coincidir intereses entre los miembros de la UE, hoy veinticinco y mañana veintisiete o veintinueve.

Juridiquement contraignant pour les Parties qui doivent en appliquer les dispositions, les échos du discours global qu’il véhicule sont appelés à être intégrés aux politiques nationales des Parties, particulièrement les pays les plus affectés par le phénomène de désertification comme le Burkina Faso. Le présent article a pour objectif de questionner la mise en œuvre de la Convention des Nations Unies sur la lutte contre la désertification dans ce pays, plus d’une vingtaine d’années après son adoption, afin de porter un regard critique sur le chemin parcouru et celui qu’il reste à parcourir pour en vue des objectifs de la Convention.

  15. The Origin of Uni-axial Negative Thermal Expansion in a Layered Perovskite

    Science.gov (United States)

    Ablitt, Chris; Craddock, Sarah; Senn, Mark; Mostofi, Arash; Bristowe, Nicholas

    Using first-principles calculations within the quasi-harmonic approximation (QHA), we explain the origin of experimentally observed uni-axial negative thermal expansion (NTE) in a layered perovskite: the Ruddlesden-Popper (RP) oxide Ca2MnO4, which has anti-ferromagnetic ordering at low temperatures and is closely related to Ca3Mn2O7, which exhibits hybrid improper ferroelectricity and uni-axial NTE in competing phases. Dynamic tilts of MnO6 octahedra, common in many complex oxides, drive the expansion of the a axis and contraction of the c axis of the tetragonal NTE phase. We find that ferroelastic RP phases with a frozen octahedral rotation are unusually compliant to particular combinations of strains along different axes. The atomic mechanism responsible is characteristic of the perovskite/rock-salt interfaces present in the RP structure. We show that the contribution from this anisotropic elasticity must be taken into account in order to accurately predict NTE over the temperature range observed in experiment. A similar compliance to cooperative strains is found in other systems with uni-axial NTE. The development of this mechanistic understanding of NTE in complex oxides may pave the way for designing tunable multifunctional materials. The authors would like to acknowledge support from the EPSRC and the Centre for Doctoral Training in Theory and Simulation of Materials.

Objetivo: comprobar teóricamente mediante la utilización de un análisis de elementos finitos, la utilidad de la conformación de túnel liso, antes de la utilización de limas rotatorias endodonticas de níquel-titanio. Métodos: se realizó una simulación numérica mediante un análisis de elementos finitos, para lo cual se construyeron modelos matemáticos de las limas rotatorias de níquel-titanio S1 y S2 de la serie Protaper®. Con el software Simulation multyphisics de Autodesk® se programaron las propiedades mecánicas de las limas y un límite de falla por fractura de 1270,588 MPa. Posteriormente se aplicó el torque recomendado por el fabricante y se fijo la punta del instrumento (sin conformación de túnel liso aplicando allí restricciones en todos los grados de libertad.Para simular la realización de la conformación de túnel liso, se aplicaron restricciones en todos los grados de libertad a una determinada distancia de la punta del instrumento, simulando de esta forma que la punta del instrumento permanecía libre. Resultados: al fijar la punta de las limas, los esfuerzos máximos fueron 1545,77 MPa para la S1 y 1306,47 MPa para la S2, observando fractura de los instrumentos. Al fijar las limas a distancia de la punta no se observó fractura. Conclusiones: se demostró teóricamente que al impedir que se atrapen la punta de las limas, se previene su fractura y que dicho atrapamiento se evita con una conformación de túnel liso, por lo que se concluye que este procedimiento es útil para prevenir la fractura de los instrumentos rotatorios de níquel-titanio.

    2015-01-01

    We study insect traffic, specifically ant traffic on a uni-directional trail which is shared by two species of ants, one of which is ‘good’ at smelling and the other ‘poor’. The two distinct species of ants are placed mixed on the same trail and individuals of both are permitted to make a U-turn when they encounter another ant in front of them. The theoretical scheme for the ant traffic is based on an asymmetric simple exclusion model. The ant traffic on the uni-directional trail is studied as a function of the number of ‘good-smelling’ ants and the evaporation probability of pheromones by keeping the number of ‘poor-smelling ants’ constant during Monte Carlo simulations.

    2001-03-01

    Several multilateral environmental agreements (MEAs) have been concluded since the Rio Earth Summit in 1992. Some of them have created economic instruments designed to arrest the rapid degradation of the planet environment. Until now and for a variety of reasons, the countries in the Priority Solidarity Zone (PSZ) have not been able to stand as very active partners in negotiating these instruments. This study seeks to respond to the question of whether the PSZ countries are in a position to derive benefit from these new instruments and what the potential impact of these instruments will be on their medium and long-term development. This question often has to be put in more basic terms: ''do the conditions required to apply these instruments exist in the PSZ countries?''.

    Full Text Available A reprodução humana assistida em uniões homoafetivas é uma temática envolta em controvérsias na sociedade contemporânea, motico pelo qual o Poder Judiciário frequentemente é acionado no intuito de dirimir os conflitos existentes. Apesar da união de pessoas do mesmo sexo ser uma configuração familiar cada vez mais frequente no Brasil, o ordenamento brasileiro ainda é frágil em relação ao deslinde da questão. A inexistência de mecanismos legais específicos no país coloca o assunto em uma posição vulnerável a questionamentos éticos, morais, médicos, religiosos e sociais. Considerando este cenário de inegável transformação da estrutura familiar, o presente trabalho teve como objetivo principal analisar as repercussões jurídicas da reprodução humana assistida nas uniões homoafetivas. As considerações trazidas por este trabalho sinalizam que mesmo diante de alguns avanços, lacunas importantes necessitam ser preenchidas no âmbito do Direito. Algumas sentenças já foram favoráveis ao reconhecimento da paternidade e maternidade de casais homoafetivos cujos filhos foram gerados por meio de métodos de reprodução assistida, entretanto, as respostas aos dilemas que envolvem esse tipo de cinstituição familiar contemporânea ainda carecem de mecanismos legais mais concretos.

  15. Uni-directional consumer-resource theory characterizing transitions of interaction outcomes

    Science.gov (United States)

    Wang, Y.; DeAngelis, D.L.; Holland, J.N.

    2011-01-01

    A resource is considered here to be a biotic population that helps to maintain the population growth of its consumers, whereas a consumer utilizes a resource and in turn decreases its growth rate. Bi-directional consumer-resource (C-R) interactions have been the object of recent theory. In these interactions, each species acts, in some respects, as both a consumer and a resource of the other, which is the basis of many mutualisms. In uni-directional C-R interactions between two species, one acts as a consumer and the other as a material and/or energy resource, while neither acts as both. The relationship between insect pollinator/seed parasites and the host plant is an example of the latter interaction type of C-R, as the insect provides no material resource to the plant (though it provides a pollination service). In this paper we consider a different variation of the uni-directional C-R interaction, in which the resource species has both positive and negative effects on the consumer species, while the consumer has only a negative effect on the resource. A predator-prey system in which the prey is able to kill or consume predator eggs or larvae is an example. Our aim is to demonstrate mechanisms by which interaction outcomes of this system vary with different conditions, and thus to extend the uni-directional C-R theory established by Holland and DeAngelis (2009). By the analysis of a specific two-species system, it is shown that there is no periodic solution of the system, and the parameter (factor) space can be divided into six regions, which correspond to predation/parasitism, amensalism, and competition. The interaction outcomes of the system transition smoothly when the parameters are changed continuously in the six regions and/or initial densities of the species vary in a smooth fashion. Varying a pair of parameters can also result in the transitions. The analysis leads to both conditions under which the species approach their maximal densities, and

El objetivo que se plantea para la presente investigación es analizar las condiciones existentes en América Latina para la posible implementación de una unión monetaria, para el desarrollo del objetivo nos apoyamos en el criterio de autores de relevante trayectoria internacional en las áreas de la economía y las finanzas como fueron Bayoumi y Eichengreen (2000, Powell y Sturzenegger (2003, también fueron consultados los premios nobel de economía Joseph Stiglitz (2016 y Robert Mundell (1965,sus significativos contribuciones resultaron de gran aporte para la presente investigación. La metodología empleada fue la realización de un análisis retrospectivo y transversal de la realidad de América Latina para implementar la unión monetaria. Tanto el objetivo planteado como la metodología, unida a otras técnicas de investigación nos permiten plantear como principales resultados, que los países latinoamericanos cuentan con insuficiencia en su capacidad para obtener la cantidad de divisas suficientes para mantener y/o estabilizar sus balanzas de pagos y cerrar sus cuentas internacionales, se plantea que el uso de numerosas monedas crea múltiples dificultades para el intercambio comercial regional. Se concluye como consideraciones finales que América Latinaaún no reúne las condiciones necesarias para que circule una moneda única ya que los modelos económicos de los diferentes países de la región son totalmente divergentes entre sí.

A análise fatorial de correspondência revelou significância para as variáveis: procedência, escolaridade e tempo de união estável. A aceitação à traição emergiu como fator de vulnerabilidade para respondentes com 1-5 anos de união estável do interior. Mulheres da capital com 6-10 anos de união estável representam a monogamia como forma de prevenção. Mulheres com maior tempo de união e nível escolar básico representam-se como invulneráveis, contrárias as que têm 1-5 anos de união e escolaridade mediana. Os resultados indicam a necessidade de mais ações com o objetivo de desnaturalizar as coerções sócio-culturais que geram representações e aproximam mulheres em união estável da AIDS.

Dans cet article, on cherche à comprendre comment le droit des gens âgés est réglé dans la législation européenne. Le vieillissement de la population européenne s'accélère, ce qui menace les systèmes de l'Etat providence. Dans cet article, en abordant la question de la discrimination contre les adultes plus âgés, on cherchera à savoir si le concept de citoyenneté, qui dépasse tout concept d'âge, représente aujourd'hui en Europe une contrainte symbolique et normative.

    In the Dutch Long Term Agreements on energy efficiency (MJA3 and MEE)the Dutch government and industry agreed to strive for a 30% energy efficiency improvement in 2020 compared to 2005. To reach more than 30%, it is not enough to optimize; instead larger process changes will be needed. An important instrument is the realization of preliminary studies and roadmaps, which are supported by the government. This memo offers an overview of relevant developments and scenarios from Agricultural, climate and environmental policy and energy prices for the Dutch sugar industry. This memo serves as input for the Preliminary study Roadmap SuikerUnie. [nl

    O defeito sensorial das aguardentes de cana destiladas na ausência de cobre já foi relacionado com a presença do dimetil sulfeto (DMS, o que revela a importância de identificar os teores deste composto eventualmente presente nesta bebida. Considerando-se, porém, o custo relativamente elevado dos métodos de cromatografia de fase gasosa até agora utilizados na determinação do DMS, foi objetivo deste trabalho avaliar a possível utilização do método de Níquel-Raney como forma de controlar o referido defeito. Nesse sentido foi estudada a relação entre os teores de DMS estimados pelo método proposto, com sua influência sensorial avaliada através de testes de aceitação. Os resultados obtidos permitiram concluir que mesmo em concentrações abaixo de 5mg/L, os testes sensoriais revelam haver alta correlação entre os teores de DMS, determinados pelo método de Níquel-Raney com a diminuição da qualidade sensorial das amostras avaliadas. Os resultados obtidos permitem propor o método de Níquel-Raney como uma opção válida no controle da presença de DMS na cachaça e assim, prevenir efeitos negativos na qualidade sensorial do produto final.

    The sensory defect of “cachaça”, when distilled in absence of copper, had been already related to dimethyl sulphide levels, pointing out the importance to control its contents in this beverage. Considering the relatively higher costs of the gas-chromatography techniques, the aim of this work was to evaluate the possible use of the Níquel-Raney method, to control the dimethyl sulphide contents. In this way, the dimethyl sulphide contents (estimated by Níquel-Raney method and its sensory deffect evaluated by acceptability sensory tests, were compared. The results showed that

    This paper summarizes the nondestructive test to determine the uni-axial compressive strength and free water content of solidified low level radioactive waste. The uni-axial compressive strength is determined by ultrasonic wave propagation speed, and the results are compared with those of compressive tests. Three methods of detecting the surface free water by ultrasonic testing are established, the ultrasonic wave speed, wave form and pulse height are used to determine the existence and amount of the surface free liquid. Possible difficulties are discussed. (author)

    X-ray powder diffraction studies and metallographic examinations in the systems UNi 5 sub(-)sub(x)Msub(x) and ZrNi 5 sub(-)sub(x)Msub(x) (M = In, Sn, Zn) revealed the existence of single phase regions up to the composition 1 : 4 : 1, i.e. up to UNi 4 M and ZrNi 4 M, respectively. Comparison between calculated and observed intensity values showed that nickel atoms, in the crystallographic positions 4(c) of the isostructural binary compounds UNi 5 or ZrNi 5 (UNi 5 -type, S.G. F43m), are substituted by M atoms. Vegard's rule is obeyed in the single phase regions of all investigated systems. The crystal structures of UNi 4 M and ZrNi 4 M are superlattice structures of the MgSnCu 4 -type (S.G. F43m). Structural correlations of these phases with corresponding binary prototypes are made in terms of stacking sequences. (orig.)

    UniSampo and Shaman are well-established analytical tools for gamma-ray spectrum analysis and the subsequent radionuclide identification. These tools are normally run locally on a Unix or Linux workstation in interactive mode. However, it is also possible to run them in batch/non-interactive mode by starting them with the correct parameters. This is how they are used in the standard analysis pipeline operation. This functionality also makes it possible to use them for remote operation over the network. Framework for running UniSampo and Shaman analysis using the standard WWW-protocol has been developed. A WWW-server receives requests from the client WWW-browser and runs the analysis software via a set of CGI-scripts. Authentication, input data transfer, and output and display of the final analysis results is all carried out using standard WWW-mechanisms. This WWW-framework can be utilized, for example, by organizations that have radioactivity surveillance stations in a wide area. A computer with a standard internet/intranet connection suffices for on-site analyses. (author)

  1. Electronic transport in the heavy fermion superconductors UPd2Al3 and UNi2Al3. Thin film studies

    Foerster, Michael

    2008-01-01

    This work addresses the electronical properties of the superconductors UPd 2 Al 3 and UNi 2 Al 3 on the basis of thin film experiments. Epitaxial thin film samples of UPd 2 Al 3 and UNi 2 Al 3 were prepared using UHV Molecular Beam Epitaxy (MBE). For UPd 2 Al 3 , the change of the growth direction from the intrinsic (001) to epitaxial (100) was predicted and sucessfully demonstrated using LaAlO3 substrates cut in (110) direction. With optimized deposition process parameters for UPd 2 Al 3 (100) on LaAlO 3 (110) superconducting samples with critical temperatures up to T c =1.75 K were obtained. UPd 2 Al 3 -AlO x -Ag mesa junctions with superconducting base electrode were prepared and shown to be in the tunneling regime. However, no signatures of a superconducting density of states were observed in the tunneling spectra. The resistive superconducting transition was probed for a possible dependence on the current direction. In contrast to UNi 2 Al 3 , the existence of such feature was excluded in UPd 2 Al 3 (100) thin films. The second focus of this work is the dependence of the resistive transition in UNi 2 Al 3 (100) thin films on the current direction. The experimental fact that the resistive transition occurs at slightly higher temperatures for I parallel a than for I parallel c can be explained within a model of two weakly coupled superconducting bands. Evidence is presented for the key assumption of the two-band model, namely that transport in and out of the ab-plane is generated on different, weakly coupled parts of the Fermi surface. Main indications are the angle dependence of the superconducting transition and the dependence of the upper critical field B c 2 on current and field orientation. Additionally, several possible alternative explanations for the directional splitting of the transition are excluded in this work. An origin due to scattering on crystal defects or impurities is ruled out, likewise a relation to ohmic heating or vortex dynamics. The

    Glycan structures attached to proteins are comprised of diverse monosaccharide sequences and linkages that are produced from precursor nucleotide-sugars by a series of glycosyltransferases. Databases of these structures are an essential resource for the interpretation of analytical data and the development of bioinformatics tools. However, with no template to predict what structures are possible the human glycan structure databases are incomplete and rely heavily on the curation of published, experimentally determined, glycan structure data. In this work, a library of 45 human glycosyltransferases was used to generate a theoretical database of N-glycan structures comprised of 15 or less monosaccharide residues. Enzyme specificities were sourced from major online databases including Kyoto Encyclopedia of Genes and Genomes (KEGG) Glycan, Consortium for Functional Glycomics (CFG), Carbohydrate-Active enZymes (CAZy), GlycoGene DataBase (GGDB) and BRENDA. Based on the known activities, more than 1.1 million theoretical structures and 4.7 million synthetic reactions were generated and stored in our database called UniCorn. Furthermore, we analyzed the differences between the predicted glycan structures in UniCorn and those contained in UniCarbKB (www.unicarbkb.org), a database which stores experimentally described glycan structures reported in the literature, and demonstrate that UniCorn can be used to aid in the assignment of ambiguous structures whilst also serving as a discovery database.

    2006-01-01

    The Unión Médica Hispano-Americana was founded during the XIII International Congress of Medicine of Paris in 1900. Its main aim was to strengthen the cultural and scientific ties among Spanish speaking countries. The first assembly took place in Madrid in the Spring of 1903. The most interesting paper presented was undoubtedly that of Manuel Tolosa Latour. He suggested creating a Diccionario Tecnológico Médico Hispano-Americano. The society had no continuity and neither did the dictionary. The reasons for this failure must be seen in the absence of economic support by political authorities in Spain and America, the organizational weakness of the Unión and the poverty of its action program, which was imbued with a triumphalist rhetoric, empty of content and highly paternalistic in its relations with the American world.

    Full Text Available Los telómeros son estructuras complejas de ADN y proteína localizadas en el extremo de los cromosomas eucariotes. Su principal función es proteger el extremo cromosomal de ser reconocido y procesado como ADNs fracturado, evitando así eventos de recombinación y fusión que conducen a inestabilidad cromosomal. El ADN telomérico consta de secuencias cortas, repetidas una tras otra, ricas en guanina; la cadena rica en guanina se extiende formando una región de cadena sencilla denominada extremo 3´ protuberante. Las proteínas por su parte, se pueden clasificar en: dsBPs, o proteínas de unión a la cadena doble, GBPs aquellas que reconocen específicamente el extremo protuberante y, proteínas que las interconectan mediante interacciones proteína-proteína. El gen PF3D7_1006800 de Plasmodium falciparum codifica para una proteína putativa similar a una GBP de Criptosporidium parvum, con el fin de establecer si esta proteína de P. falciparum presenta la capacidad de unión al ADN telomérico del parásito, se produjo una proteína recombinante a partir de la región codificante del gen, se purificó y se utilizó en ensayos de unión a ADN, y en la generación de anticuerpos policlonales específicos contra PfGBP. Nuestros resultados indican que la proteína de P. falciparum es una proteína nuclear con capacidad de unión al ADN telomérico in vitro, por lo que podría ser parte del complejo proteico encargado de proteger y/o mantener el telómero in vivo.

    Full Text Available Officine de l’âme et de l’esprit, la bibliothèque représente ce lieu où se forme un patrimoine, individuel ou collectif, et où s’élabore une construction, personnelle ou non, référant à une histoire, elle-même relative à une mémoire propre. Afin de cerner ce qu’il en est au Maroc, nous interrogerons, sous un angle ethnologique, le rapport des lecteurs à leur bibliothèque, qu’elle soit publique ou privée, afin non seulement de comprendre quels sont les livres appelés à constituer le patrimoine dont elle sera le dépositaire : à faire patrimoine, mais également cerner les représentations qui lui sont attachées, la mémoire à laquelle elle réfère, les usages qui en découlent, et le rôle qui lui est attribué. Alors que la bibliothèque publique fait l’objet d’usages limités et strictement fonctionnels de la part de ses usagers, la bibliothèque privée donne lieu à davantage d’appropriations personnelles. Nous tenterons de comprendre pourquoi les pratiques attachées à la bibliothèque sont davantage, voire essentiellement, retranchées dans le domaine privé, en interrogeant les usages réels, c'est-à-dire privés, de la bibliothèque. On observera que les bibliothèques privées sont dépositaires d’un patrimoine traditionnel tirant son essence de l’histoire arabe et d’une mémoire de l’Antiquité. Un patrimoine, nous le verrons, davantage véhiculé par l’esthétique propre aux ouvrages qui le portent que par leur contenu. A cette fonction esthétique de la bibliothèque s’ajoute un rôle distinctif, chaque individu en effet, au travers de sa bibliothèque racontant son histoire relative à une mémoire singulière.

    "Selon les calculs de Bohm, chaque centimètre cube d'espace vide contient plus d'énergie que ce qu'on pourrait trouver dans toute la matière de l'univers connu. L'univers entier, tel que nous le connaissons, n'est qu'une simple petite trace d'excitation quantifiée en forme de vague, une ride dans cet immense océan d'énergie cosmique. C'est cet arrière-plan énergétique caché qui engendre les projections tridimensionnelles constituant le monde phénoménal que nous percevons dans notre vie de tous les jours... " N'importe quel événement, objet ou entité, observable et descriptible, quel qu'il soit, est abstrait, d'un flux uni, indéfinissable et inconnu, le holomouvement... " David Bohm offre une nouvelle vision globale du monde qui représente une révision radicale de l'image de l'univers découlant de la science traditionnelle. Bien qu'inspiré à l'origine par les paradoxes de la physique quantique relativiste, son modèle offre de profondes implications concernant un vaste éventail de discipl...

En este trabajo se aborda el reto que tiene la UE para ofrecer una ayuda humanitarian independiente, al responder a las emergencias internacionales, al tiempo que trata de coordinar y dotar de mayor coherencia a su política exterior, a partir del análisis de la manera como la Unión concilia estos objetivos conflictivos. En particular, se estudia cómo interactúan las políticas de cooperación para el desarrollo y la de ayuda humanitaria de la UE, la política de comercio común, y la política exterior y de seguridad. Por último, en las consideraciones finales se argumenta que a pesar de que la ayuda humanitaria se haya incorporado en el Tratado de Lisboa como una política más de su acción exterior, esta debe ser independiente, al estar sustentada en la solidaridad internacional, y no en los principios aplicables al resto de las políticas de acción exterior, lo que dificulta establecer sinergias positivas con las otras políticas de la acción exterior de la UE.

These rights are the core of the values that are proposed as a scenario capable of achieving these aims of prosperity and democracy. But these values will not appear psycho-culturally by chance. They require the appropriate attitudes and practices, consistent with acting according to these rights.

    An automatic Uni- or Multi-modal Inteligent Seizure Acquisition (UISA/MISA) system is highly applicable for onset detection of epileptic seizures based on motion data. The modalities used are surface electromyography (sEMG), acceleration (ACC) and angular velocity (ANG). The new proposed automatic...... algorithm on motion data is extracting features as “log-sum” measures of discrete wavelet components. Classification into the two groups “seizure” versus “nonseizure” is made based on the support vector machine (SVM) algorithm. The algorithm performs with a sensitivity of 91-100%, a median latency of 1...... second and a specificity of 100% on multi-modal data from five healthy subjects simulating seizures. The uni-modal algorithm based on sEMG data from the subjects and patients performs satisfactorily in some cases. As expected, our results clearly show superiority of the multimodal approach, as compared...

    Magnetization measurements under direct electric current were performed in a toroidal magnetic ordered state of UNi4B to test a recent theoretical prediction of current-induced magnetization in a metallic system lacking local-inversion symmetry. We found that electric current parallel to [2\\bar{1}\\bar{1}0] and [0001] in the hexagonal 4-index notation induces a uniform magnetization along the [01\\bar{1}0] direction. The observed behavior of the induced magnetization is essentially consistent with the theoretical prediction; however, it also shows an inconsistency suggesting that the antiferromagnetic state of UNi4B could not be simply regarded as a uniform toroidal order in the ideal honeycomb layered structure.

    In developing the fuel compact fabrication technology, and fuel graphite material to meet the required material properties, it is essential to investigate the relationship among the process parameters of the matrix graphite powder preparation, the fabrication parameters of fuel element green compact and the heat treatments conditions and the material properties of fuel element. It was observed, during this development, that the pressing technique employed for the compaction fabrication prior to the two successive heat treatments (carbonization and final high temperature heat treatment) was of extreme importance in determining the material properties of the final compact product. In this work, the material behavior of the uni-axially pressed graphite matrix during the carbonization and final heat treatment are evaluated and summarized along the different directions, viz., perpendicular and parallel directions to pressing direction. In this work, the dimensional variations and variations in thermal expansion, thermal conductivity and Vickers hardness of the graphite matrix compact samples in the axial and radial directions prepared by uni-axial pressing are evaluated, and compared with those of samples prepared by cold isostatic pressing with the available data. From this work, the followings are observed. 1) Dimensional changes of matrix graphite green compacts during carbonization show that the difference in radial and axial variations shows a large anisotropic behavior in shrinkage. The radial variation is very small while the axial variation is large. During carbonization, the stresses caused by the force would be released in to the axial direction together with the phenolic resin vapor. 2) Dimensional variation of compact samples in perpendicular and parallel directions during carbonization shows a large difference in behavior when compact sample is prepared by uni-axial pressing.

    We have determined unusual magnetic ordering of the hexagonal intermetallic uranium compound UNi{sub 4}B via neutron diffraction. In the easy basal plane the U-moments have triangular symmetry with antiferromagnetic interactions. Along the hard c axis ferromagnetic coupling occurs. Below T{sub N} = 20 K only two out of every three U-moments of 1.2 {mu}{sub B} order in vortex-like arrangements around the third paramagnetic spin. This novel magnetic structure is related to the occurrence of a crystallographic superstructure. Previously observed anomalies in bulk properties below T{sub N} are attributed to unconventional spin-wave excitations associated with this type of ordering. (orig.).

    The use of FRP composite materials in aerospace, aviation, marine, automotive and civil engineering industry has increased rapidly in recent years due to their high specific strength and stiffness properties. The structural members contrived from such composite materials are generally subjected to complex loading conditions and leads to multi-axial stress conditions at critical surface localities. Presence of notches, much required for joining process of composites, makes it further significant. The current practice of using uni-axial test data alone to validate proposed material models is inadequate leading to evaluation and consideration of bi-axial test data. In order to correlate the bi-axial strengths with the uni-axial strengths of GFRP composite laminates in the presence of a circular notch, bi-axial tests using four servo-hydraulic actuators with four load cells were carried out. To determine the in-plane strength parameters, bi-axial cruciform test specimen model was considered. Three different fibre orientations, namely, 0°, 45°, and 90° are considered with a central circular notch of 10 mm diameter in the present investigation. From the results obtained, it is observed that there is a reduction in strength of 5.36, 2.41 and 13.92% in 0°, 45°, and 90° fibre orientation, respectively, under bi-axial loading condition as compared to that of uni-axial loading in laminated composite.

Foram testados dois sistemas de eluição; o primeiro operou com a passagem direta e o segundo com a recirculação do eluente. Em seguida, foram realizados dez ciclos consecutivos de sorção-dessorção em duas colunas de leito fixo, uma regenerada com o eluente H2SO4 (0,1 M e outra com MgSO4/H2SO4 (pH 3, em sistema de recirculação do eluente. As etapas de sorção e dessorção foram realizadas em 30 e 2h, respectivamente, representando 20 dias de uso contínuo da biomassa. Foi observada alta quantidade recuperada de níquel nas etapas de eluição (aproximadamente 95%. Ao final do décimo ciclo, verificou-se que a alga Sargassum filipendula continuava apresentando valores elevados da capacidade de remoção de níquel da solução, mostrando-se como alternativa eficiente de tratamento de águas residuárias contendo metais. A regeneração da biomassa apresentou baixo custo, além de ter facilitado o processo de tratamento que dispensou trocas sucessivas da biomassa.

    The widening gap between known proteins and their functions has encouraged the development of methods to automatically infer annotations. Automatic functional annotation of proteins is expected to meet the conflicting requirements of maximizing annotation coverage, while minimizing erroneous functional assignments. This trade-off imposes a great challenge in designing intelligent systems to tackle the problem of automatic protein annotation. In this work, we present a system that utilizes rule mining techniques to predict metabolic pathways in prokaryotes. The resulting knowledge represents predictive models that assign pathway involvement to UniProtKB entries. We carried out an evaluation study of our system performance using cross-validation technique. We found that it achieved very promising results in pathway identification with an F1-measure of 0.982 and an AUC of 0.987. Our prediction models were then successfully applied to 6.2 million UniProtKB/TrEMBL reference proteome entries of prokaryotes. As a result, 663,724 entries were covered, where 436,510 of them lacked any previous pathway annotations.

    Full Text Available Approximately 45.7 million people in the United States are uninsured and unknown numbers of this population are underinsured, severely limiting their access to medical care. To address this problem, people use innovative strategies to increase their access through cross-border care options. The U.S.-Mexico border provides unique challenges and opportunities for health care in this context. The lower cost of medical and dental procedures and medications in Mexico makes that country an attractive alternative for low-income populations in the United States. Thus segments of the U.S. population practice transnational medical consumerism in an attempt to optimize their health by using the resources available in both countries. This practice has economic benefits for the people who access health care at an affordable rate and for the medical markets of the country providing the care. Drawing on data collected in the field in 2002, 2004, and 2005, this paper presents some of the complexities and dynamics of medical pluralism occurring at the U.S.-Mexico border.Environ 45,7 millions de personnes vivant aux Etats-Unis n’ont pas de couverture sociale et nombreux sont celles à être sous-assurées, ce qui limite considérablement leur accès aux soins. Face à ce problème, les Américains font preuve d'ingéniosité pour améliorer leur accès aux soins : ils se font soigner au-delà des frontières. Dans ce contexte, la frontière entre les Etats-Unis et le Mexique offre des opportunités uniques de soins. Le Mexique constitue en effet une alternative séduisante pour les Américains à faible revenu, car les tarifs des actes médicaux et dentaires, et des médicaments, sont nettement inférieurs à ceux en vigueur aux Etats-Unis. Ainsi, certains Américains pratiquent le consumérisme médical transnational et recourent aux ressources disponibles dans les deux pays afin d’optimiser leur santé. Cette pratique présente des avantages économiques

    A study related to the fatigue behaviour of natural fibre-reinforced composites was conducted to expand their range of product applications. A uni-directional flax-epoxy composite was fabricated and several conditions of tension-tension fatigue tests were performed. During fatigue testing......, the composite showed an increase of stiffness, a typical observation for natural fibre-reinforced composites, and this was found to be accompanied by accumulation of residual strain. A clear linear relationship was found between the stiffening effect and the residual strain. In addition, it was revealed...... that the fatigue behaviour was clearly influenced by the frequency of cyclic loading. Lower frequencies induced more significant stiffening and shorter fatigue life. These results suggest that fatigue damaging is progressing simultaneously with the stiffening effect in natural fibre-reinforced composites...

    Full Text Available Cet article analyse le mouvement des Frères musulmans (Ikhwan al-muslimin sous ses différentes formes. Ce mouvement islamique mondial, prosélyte, apparu dans la foulée des deux guerres mondiales, a connu une véritable résurgence, voire une résurrection à partir des années 1980 dans les pays musulmans. Fondé en 1928 par l’Egyptien Hassan al-Banna (1906-1949, le Printemps arabe lui a conféré un souffle nouveau. Le mouvement des Frères musulmans s’est notamment imposé à la tête de l’Etat le plus peuplé du monde arabe, l’Egypte. Là où ce mouvement s’implante, il crée ses propres syndicats, ses associations d’étudiants, de médecins, de travailleurs, ses institutions bancaires islamiques, etc. L’auteur examine plus particulièrement la nature de l’Etat islamique et les traits essentiels de la doctrine politico-religieuse des Frères musulmans et des partis islamistes qui s’en inspirent au Maghreb et ailleurs. Il décrypte leur approche économique, sociale et financière à travers les différentes techniques de la finance islamique. Si le modèle financier musulman est motivé par des considérations de justice sociale (‘adala ijtima’iya et le rejet de l’usure (ribâ, l’auteur considère néanmoins que la vision de ce modèle est essentiellement capitaliste en visant à maximiser les profits. Il appelle à recentrer l’approche des banques islamiques et à les adapter afin qu’elles soient aussi accessibles au financement des petits projets lancés par des déshérités.

    Full Text Available La Deuxième Guerre mondiale constitue une période clé, au Royaume-Uni, dans l’histoire des femmes et de leur représentation cinématographique. A travers l’analyse de chiffres officiels concernant les femmes et l’emploi pendant la guerre cet article montre à quel point les femmes jouaient un rôle essentiel dans l’« effort de guerre ». Il examine ensuite quelles réponses le cinéma a apporté par rapport à cet appel aux femmes, mettant en avant à l’écran les nouveaux rôles sollicités auprès des femmes mais aussi, parfois, continuant à appuyer des attitudes plus traditionnelles. En analysant une grande variété de films produits pendant la guerre, de genres cinématographiques différents – films de fiction, documentaires, films émanant des forces armées – on est témoin de l’émergence d’un nouveau type d’héroïne cinématographique, l’« héroïne de guerre », innovatrice dans le courage et l’esprit d’initiative dont elle peut faire preuve mais, en fin de compte, respectueuse des frontières des rôles traditionnels associés aux genres masculins et féminin. En conclusion, l’article se demande dans quelle mesure ces rôles cinématographiques innovateurs dans le domaine du genre ont pu se perpétuer dans la période d’après guerre.

    The optical vibrations of hydrogen in TbNiAlH 1.4 and UNiAlH 2.0 were investigated by means of inelastic neutron scattering. The experimental data were analysed, including multiphonon neutron scattering contributions, calculated in an isotropic harmonic approximation. At least two fundamental H optical peaks were observed in TbNiAlH 1.4 , and were assigned to the vibrational modes of hydrogen atoms occupying different interstitial sites in the metal sublattice. The high-energy part of the UNiAlH 2.0 spectra is characterized by strong anharmonicity, and a broad fundamental band. The latter can be accounted for by a large dispersion of phonon modes due to the strong H-H interactions, and/or different metal-hydrogen force constants, which may originate from different metal atoms surrounding the H atoms in the unit cell

    The climatic change represents the most severe danger to the durable world development, public health and future prosperity. This document concerning the gas releases with greenhouse effect is a report of the Senate Planning delegation regarding the economic and fiscal tools envisaging abatement of releases of gases with greenhouse effect. These issues are presented in four chapters titled as follows: 1. Since the scientific evidencing, requirement of managing the releases of gas with greenhouse effect has been unanimously recognized at the summits of Rio (1992) and Kyoto (1997); 2. The economic theory suggests instruments for reducing the gas releases with greenhouse effect at a minimum cost; 3. Challenges and ways of international cooperation in the field of climatic change; 4. Joining the political will with the pragmatic use of the economic instruments at national scale. The document contains a synthesis of proposals directed towards the following goals: international negotiations relating to climatic change; creating the community framework of managing the gas releases resulting in greenhouse effect; establishing national measures for managing the gas releases leading to greenhouse effect; actions to be undertaken by the territorial collectivities.

    Full Text Available La Unión Europea persigue, entre sus objetivos básicos, alcanzar una convergencia en el PIB per cápita entre las regiones. El propósito del presente artículo es medir el nivel de desarrollo económico y social de las regiones más atrasadas de los países del sur de la Unión en el año 2006. En esencia, se verifica si las regiones incluidas en el Objetivo “Convergencia” en el marco presupuestario 2007-2013, presentaban, al principio del período (año 2006, y como resultado esperado, un menor nivel de desarrollo, que las regiones que perdieron esta consideración de zonas más atrasadas de la Unión, de acuerdo al valor del PIB per cápita. Con este objetivo, se construye un indicador sintético de desarrollo económico y social y se utiliza como metodología de ponderación el análisis de componentes principales, con la agregación de un amplio conjunto de variables de desarrollo económico y social, que complementan al PIB per cápita como referencia para medir el desarrollo de una región en un año determinado. Los resultados encontrados muestran que seis regiones comunitarias, que se consideran Objetivo “Convergencia” para la Unión Europea, es decir, que se encuentran entre las más pobres, arrojan valores relativamente altos en el índice de desarrollo, en tanto que, paradójicamente, siete regiones, que han superado el umbral del PIB per cápita en el año de estudio, alcanzan una posición baja en la clasificación, por lo que se plantea la idoneidad de incorporar otras variables en la evaluación del desarrollo económico y social de las regiones comunitarias, en el marco de la futura política regional.

    Full Text Available Health selectivity posits that individuals who practice preventive health behaviors are more likely to migrate to the United States, and this has been proposed as one explanation of the Latino Paradox. This paper examines evidence for health selection in the context of reproductive health using national survey data from Mexico (the longitudinal Mexico Family Life Survey [MxFLS], 2002 and 2005 waves and the United States (the National Survey of Family Growth [NSFG], 2002. We compared sexual behaviors and contraceptive practices of Mexican women residing in Mexico who subsequently migrated to the United States with those who remained in Mexico and with Mexican immigrants in the United States. MxFLS respondents who migrated to the United States had a younger mean age, and a larger proportion had no children compared to MxFLS nonmigrants. Within the MxFLS sample, a smaller proportion of women who migrated had ever had vaginal sex, though this difference was nonsignificant with adjustment for sociodemographic factors. No sexual behavior or contraceptive use measures varied between Mexican migrants and nonmigrants within the MxFLS. The mean lifetime number of sexual partners was lower for MxFLS respondents than for Mexican immigrants in the NSFG. Smaller proportions of MxFLS respondents reported using hormonal methods or condoms relative to NSFG respondents. We found no evidence for health selectivity with regard to sexual behaviors or contraceptive practices, underscoring the importance of continued attention to the factors that influence the adaptation trajectories following U.S. migration.L’hypothèse de la sélection par la santé selon laquelle les individus qui adoptent des comportements de prévention sont plus susceptibles d’immigrer aux Etats-Unis, a été proposée comme une explication au paradoxe latino.

    This work addresses the electronical properties of the superconductors UPd{sub 2}Al{sub 3} and UNi{sub 2}Al{sub 3} on the basis of thin film experiments. Epitaxial thin film samples of UPd{sub 2}Al{sub 3} and UNi{sub 2}Al{sub 3} were prepared using UHV Molecular Beam Epitaxy (MBE). For UPd{sub 2}Al{sub 3}, the change of the growth direction from the intrinsic (001) to epitaxial (100) was predicted and sucessfully demonstrated using LaAlO3 substrates cut in (110) direction. With optimized deposition process parameters for UPd{sub 2}Al{sub 3} (100) on LaAlO{sub 3}(110) superconducting samples with critical temperatures up to T{sub c}=1.75 K were obtained. UPd{sub 2}Al{sub 3}-AlO{sub x}-Ag mesa junctions with superconducting base electrode were prepared and shown to be in the tunneling regime. However, no signatures of a superconducting density of states were observed in the tunneling spectra. The resistive superconducting transition was probed for a possible dependence on the current direction. In contrast to UNi{sub 2}Al{sub 3}, the existence of such feature was excluded in UPd{sub 2}Al{sub 3}(100) thin films. The second focus of this work is the dependence of the resistive transition in UNi{sub 2}Al{sub 3}(100) thin films on the current direction. The experimental fact that the resistive transition occurs at slightly higher temperatures for I parallel a than for I parallel c can be explained within a model of two weakly coupled superconducting bands. Evidence is presented for the key assumption of the two-band model, namely that transport in and out of the ab-plane is generated on different, weakly coupled parts of the Fermi surface. Main indications are the angle dependence of the superconducting transition and the dependence of the upper critical field B{sub c{sub 2}} on current and field orientation. Additionally, several possible alternative explanations for the directional splitting of the transition are excluded in this work. An origin due to scattering on

    Although minimally invasive approaches for surgical treatment of stand-alone atrial fibrillation have gained popularity for the past decade, ablation technology and extensive lesion sets play a major role in the achievement of a successful procedure, especially in presence of persistent and long-standing persistent atrial fibrillation. We evaluated clinical outcomes after totally endoscopic biatrial epicardial ablation of persistent atrial fibrillation with a novel integrated uni-bipolar radiofrequency device. Forty-nine (49) consecutive patients with stand-alone atrial fibrillation underwent right-sided monolateral thoracoscopic surgical ablation with a novel integrated uni-bipolar radiofrequency energy delivery and temperature-controlled technology. Atrial fibrillation was persistent in 13 (26.5%) of 49 and long-standing persistent in 36 (73.5%) of 49 patients. Mean ± SD age was 60.6 ± 10.3 years. Median duration of atrial fibrillation was 74 months. Mean ± SD left atrial diameter was 44.7 ± 4.0 mm. Epicardial en bloc isolation of all pulmonary veins (box lesion) and additional ablation of the right atrial free wall was successfully performed via minimally invasive approach without any intraoperative and postoperative major complications. Intraoperative entrance and exit block was achieved in 77.5% (38/49) and 91.8% (45/49) of patients, respectively. Mean ± SD ablation time was 16.3 ± 4.8 minutes. No intensive care unit stay was required. Postoperative sinus rhythm was achieved in 93.8% (30/32) patients, and no pacemaker implantation was required. At 13 months, 87.7% (43/49) of patients were in sinus rhythm; 71.4% (35/49) were free from antiarrhythmic drugs and 75.5% (37/49) from oral anticoagulation. Integrated uni-bipolar radiofrequency ablation technology showed to be effective for the surgical treatment of atrial fibrillation with a total endoscopic approach. A versapolar suction device with extensive right-left atrial lesion set may further improve

    This paper describes a study of the physico-chemical state of radio-cerium in dilute solutions on the tracer scale, as a function of the pH of the solution. The way in which this radioelement is transported in the blood is studied in vitro and in vivo, with reference to the ionic or colloidal state of the radio-cerium used. The distribution of cerium amongst the various components of the blood is studied by a new method of blood fractionation and by paper electrophoresis. Evidence of a cerium globulin connection is shown in the case of ionic cerium. A study of the initial distribution of radio-cerium in rats, after intravenous administration of ionic or colloidal solutions, shows considerable differences according to the physico-chemical state of the cerium injected. (author) [French] Ce travail presente une etude de l'etat physico-chimique du radiocerium en solutions diluees a l'echelle des indicateurs, en fonction du pH de la solution. En fonction de l'etat ionique ou colloidal du radiocerium utilise, le mode de transport de ce radioelement dans le sang est etudie in vitro et in vivo. La distribution du cerium entre les differents constituants du sang est etudiee par une methode nouvelle de fractionnement du sang et par electrophorese sur papier. L'existence d'une liaison cerium-globuline est mise en evidence dans le cas du cerium ionique. L'etude de la distribution initiale du radiocerium, chez le rat apres administration par voie veineuse de solutions ionique ou colloidale, montre des differences importantes en fonction de l'etat physico-chimique du cerium injecte.

    The Battery of Reasoning Tests 5 (BPR-5) aims to assess the reasoning ability of individuals, using sub-tests with different formats and contents that require basic processes of inductive and deductive reasoning for their resolution. The BPR has three sequential forms: BPR-5i (for children from first to fifth grade), BPR-5 - Form A (for children from sixth to eighth grade) and BPR-5 - form B (for high school and undergraduate students). The present study analysed 412 questionnaires concerning BPR-5i, 603 questionnaires concerning BPR-5 - Form A and 1748 questionnaires concerning BPR-5 - Form B. The main goal was to test the uni-dimensionality of the battery and its tests in relation to items using the bi-factor model. Results suggest that the g factor loadings (extracted by the uni-dimensional model) do not change when the data is adjusted for a more flexible multi-factor model (bi-factor model). A general reasoning factor underlying different contents items is supported.

  14. Comparative Study on Uni- and Bi-Directional Fluid Structure Coupling of Wind Turbine Blades

    Full Text Available The current trends of wind turbine blade designs are geared towards a longer and slender blade with high flexibility, exhibiting complex aeroelastic loadings and instability issues, including flutter; in this regard, fluid-structure interaction (FSI plays a significant role. The present article will conduct a comparative study between uni-directional and bi-directional fluid-structural coupling models for a horizontal axis wind turbine. A full-scale, geometric copy of the NREL 5MW blade with simplified material distribution is considered for simulation. Analytical formulations of the governing relations with appropriate approximation are highlighted, including turbulence model, i.e., Shear Stress Transport (SST k-ω. These analytical relations are implemented using Multiphysics package ANSYS employing Fluent module (Computational Fluid Dynamics (CFD-based solver for the fluid domain and Transient Structural module (Finite Element Analysis-based solver for the structural domain. ANSYS system coupling module also is configured to model the two fluid-structure coupling methods. The rated operational condition of the blade for a full cycle rotation is considered as a comparison domain. In the bi-directional coupling model, the structural deformation alters the angle of attack from the designed values, and by extension the flow pattern along the blade span; furthermore, the tip deflection keeps fluctuating whilst it tends to stabilize in the uni-directional coupling model.

    Full Text Available La incorporación de nanopartículas de carburos, nitruros, óxidos o diamante en una matriz metálica, generalmente muestran mejoras en la dureza, en la resistencia al desgaste y a la corrosión, comparado con un recubrimiento del metal puro. Estos recubrimientos compuestos se pueden obtener mediante la técnica de electrodeposición, logrando economía y calidad en los depósitos. Los recubrimientos de níquel modificados con nanopartículas de diamante (Ni-D, fueron aplicados sobre un acero AISI SAE 1016 mediante la técnica de electrodeposición desde una solución típica Watts sin aditivos, que contiene nanopartículas de diamante. El efecto que ejercen algunas variables que intervienen en el proceso de electrodeposición como: densidad de corriente, velocidad de agitación y concentración de partículas en el baño, en la dureza y en la resistencia a la corrosión-erosión, se estudiaron mediante un diseño factorial completamente aleatorizado 2k. La resistencia a la corrosión- erosión se evaluó mediante el monitoreo del potencial de corrosión de las probetas con recubrimiento sometidas a un fluido corrosivo y abrasivo en movimiento. Los recubrimientos compuestos de Ni-D obtenidos presentan mejor resistencia a la corrosión-erosión que los recubrimientos de níquel puro. Los recubrimientos más resistentes a la corrosión-erosión fueron los obtenidos a 5 A/dm², 900 rpm y 10 g/L de diamante.

    The new industrial political tools based on the sustainable development of productive activities, and originating at the Rio Conference in 1992, late introduced by the EU, the Government and voluntary organizations (ISO, CEM, UNI) are gradually entering the market, thereby underling their effect in terms of industrial competitiveness. The main tools were examined in the report and mostly refer to the voluntary ones which, in surpassing the 'command and control' logic, increasingly tend to get close to traditional fiscal, tariff and financial ones. Voluntary agreements, environmental management systems (EMAS, norme ISO 14001), the risk prevention systems (UNI 10617), certification (Ecolabel, ISO 14040) and environment communication tools (environment balance sheet, environmental report, environmental statement) are synthetically described [it

    Full Text Available La Unión Europea considera que la mejor manera de potenciar el crecimiento social y económico es fomentar las iniciativas emprendedoras pero, desafortunadamente, todavía hay muy pocos europeos estableciendo sus propios negocios. Por ello, el propósito de este estudio es relacionar el interés de los ciudadanos europeos en autoemplearse con los riesgos y barreras que perciben a la hora de enfrentarse a este proceso emprendedor. El análisis planteado cubre la totalidad de la Unión Europea de manera exploratoria, debido fundamentalmente a la falta de datos pasados de los 10 países nuevos miembros de la Unión. Los resultados muestran Ias grandes diferencias existentes entre los estados miembros y la necesidad de profundizar en la explicación de las dimensiones obtenidas. Desde un punto de vista práctico, se plantea que políticas de promoción de la actividad emprendedora se han de desarrollar fundamentalmente en los ámbitos estatal y regional.The European Union considers that the best way to boost the social and economic growth is to encourage entrepreneurial initiatives but, unfortunately, there are still very few Europeans setting up their own business. Therefore, the aim of this study is to relate the interest of Europeans citizens on being self-employed with the perceived risks and barriers to be faced up in this entrepreneurial process. The analysis covers the entire European Union, working on an exploratory base mainly due to the lack of past data about the ten new European Union Members States. The results show the great differences between the Member States and ask for a deep insight explaining the obtained dimensions. From a practical point of view, it is proposed that entrepreneurship promotion policies should be performed at the national and regional level.

    Full Text Available Con el presente trabajo se pretende incorporar al estudio del aborto en México la perspectiva generacional y la distinción según el tipo de unión, dos dimensiones que no han sido consideradas en los estudios publicados hasta la fecha. Los datos utilizados corresponden a los de la Encuesta Nacional de la Dinámica Demográfica levantada en 1997. Entre los resultados obtenidos destaca el relativo a la reducción que experimentó el aborto entre las jóvenes (menores de 30 años de las generaciones nacidas a fines de los años cuarenta y aquellas que lo hicieron veinte años después, a fines de los sesenta. La distinción por tipo de unión nos permite atribuir esta disminución a las mujeres casadas, que casi exclusivamente eran quienes lo practicaban, y evaluar su impacto reductivo sobre la fecundidad en 1.2 nacimientos evitados en las generaciones mayores y 0.5 en las mas jóvenes. Las mujeres en uniones libres no superan los 0.6 nacimientos evitados en ninguna de las dos generaciones. Al aplicar el factor de separación propuesto, estas diferencias se traducen en relaciones de un aborto espontáneo por casi seis inducidos entre las casadas de más edad y solamente uno de cada dos entre las más jóvenes. Finalmente la distribución según el método anticonceptivo utilizado nos indica que las jóvenes en unión libre están más eficazmente protegidas que las casadas.

    Purpose: Fluoroscopically guided transcervical fallopian tube recanalization is recognized as an important step in the workup of female infertility. In the present study, a simplified set of recanalization instruments was tested. Materials and Methods: Forty-two women with infertility and sonographically confirmed or suspected uni- or bilateral tubal occlusion were examined. After vaginal placement of a plastic speculum and fixation of a tenaculum, a 4F glide catheter with a 0.89 mm glidewire was advanced transcervically. After documentation of tubal occlusion by hysterosalpingography, the uterotubal junction was catheterized with the same instruments. Under fluoroscopic guidance, the glidewire was negotiated beyond the intramural portion of the tube. Selective salpingography documented the outcome of the recanalization. Results: Hysterosalpingography confirmed tubal occlusions in 26 of 42 patients (in 12 cases unilateral and in 14 cases bilateral). Fallopian tube recanalization was successful in 23 of 26 patients (technical success rate of 88%). The resulting fertility rate was 30% (7/23), without any ectopic pregnancy. Complications such as tubal perforation, infection, or bleeding did not occur. Tubal catheterization was straightforward and smooth in 17/23 cases. For a hyperflexed uterus (6/23), a curved tip of the catheter was helpful in tubal probing. (orig.)

    2004-01-01

    We present a dynamical analysis of a classical billiard chain-a channel with parallel semi-circular walls, which can serve as a model for a bent optical fibre. An interesting feature of this model is the fact that the phase space separates into two disjoint invariant components corresponding to the left and right uni-directional motions. Dynamics is decomposed into the jump map, a Poincare map between the two ends of a basic cell, and the time function, travelling time across a basic cell of a point on a surface of section. The jump map has a mixed phase space where the relative sizes of the regular and chaotic components depend on the width of the channel. For a suitable value of this parameter, we can have almost fully chaotic phase space. We have studied numerically the Lyapunov exponents, time auto-correlation functions and diffusion of particles along the chain. As a result of the singularity of the time function, we obtain marginally normal diffusion after we subtract the average drift. The last result is also supported by some analytical arguments

    A review of the waste-disposal research and development carried out in the United States of America is given. The major research effort concerns the conversion of high-level liquid wastes into solids. At Hanford and Oak Ridge low-level wastes are disposed to the ground in pits, cribs and lagoons. Geochemical studies related to waste disposal are conducted at Hanford, Oak Ridge and the University of North Carolina. Experiments with soil columns ate described ; these are more effective for the decontamination of waste streams than either cribs or pits. The most suitable exchange materials for the soil columns are found to be vermiculite supported by rock phosphate and the latter supported by graded gravel. The progress of research work on the possibility of injecting radioactive liquid wastes into porous formations through deep wells and disposing of radioactive wastes in impermeable formations by hydraulic fracturing is outlined.

    2018-05-01

    This work presents the energy absorption capacity of hybrid fiber reinforced concrete made with hooked end steel fibers (0.5 and 0.75%) and straight polyester fibers (0.5, 0.8, 1.0 and 2.0%). Compressive toughness (energy absorption capacity) under uni-axial compression was evaluated on 100 × 200 mm size cylindrical specimens with varying steel and polyester fiber content. Efficiency of the hybrid fiber reinforcement is studied with respect to fiber type, size and volume fractions in this investigation. The vertical displacement under uni-axial compression was measured under the applied loads and the load-deformation curves were plotted. From these curves the toughness values were calculated and the results were compared with steel and polyester as individual fibers. The hybridization of 0.5% steel + 0.5% polyester performed well in post peak region due to the addition of polyester fibers with steel fibers and the energy absorption value was 23% greater than 0.5% steel FRC. Peak stress values were also higher in hybrid series than single fiber and based on the results it is concluded that hybrid fiber reinforcement improves the toughness characteristics of concrete without affecting workability.

    Full Text Available To describe the integration process of grafts of total human skin and keloid in hamster (Mesocricetus auratus cheek pouch, whose sub-epithelium is naturally an "Immunologically Privileged Site". Fragments of human normal skin and keloid from the breast region of mulatto female patients were transplanted into the cheek pouch subepithelium in situ. Surgical procedure and grafted pouches for microscopic exam at several time points of the transplantation were standardized. The integration of grafted fragments of human skin and keloid was seen in late periods (84 days since the microscopic assessment showed the presence of blood vases within the conjunctive tissue of grafted fragments. It was also possible to see among the grafted fragments the epithelium, the appearing of early cellular infiltrated, epithelial secretion of keratin, the presence of melanocytes, and delayed changes on the aspect of collagen fibers of conjunctive tissue. Pooled results allow to define hamster cheek pouch sub-epithelium as an experimental model to investigating heterologous graft physiology of human total skin and keloid with epithelium.Descrever a integração dos enxertos de pele total humana e quelóide na bolsa jugal do hamster (Mesocricetus auratus, cujo subepitélio é, naturalmente, um "Local de Privilégio Imunológico".

    Full Text Available Resumo A aplicação de revestimentos de ligas de níquel é comumente realizada na indústria de petróleo e gás para aumento da vida de equipamentos em ambientes agressivos, dado que este procedimento melhora a resistência à corrosão, sem um aumento significativo do custo de produção quando comparado com equipamentos maciços fabricados com outras ligas. Normalmente, as juntas são soldadas pelos processos de eletrodos revestidos, MIG/MAG ou TIG. Neste aspecto, o processo eletroescória realiza deposições com elevada energia de soldagem e baixa diluição, podendo ser uma opção interessante, uma vez que proporciona uma elevada produtividade, permitindo a soldagem com aplicação de apenas uma camada. O presente trabalho avalia propriedades mecânicas, microestruturais e de corrosão de revestimentos de liga de níquel 625 depositada em aço carbono ASTM A516 Grau 70 pelo processo eletroescória, tanto na condição como soldado quanto tratado termicamente. A deposição foi realizada com uma e duas camadas sobre chapas de dimensão 50x400x400 mm, na posição plana e energia de soldagem média de 11,7 kJ/mm. Após a soldagem realizou-se tratamento térmico a 620°C por 10 horas, sendo esta condição comparada ao estado de como soldado. Os ensaios de dobramento não indicaram evidências de defeitos. A avaliação microestrutural realizada por microscopia ótica (MO, eletrônica de varredura (MEV e eletrônica de transmissão (MET mostrou uma microestrutura austenítica para o depósito com pequena fração volumétrica de fases secundárias e o tratamento térmico de alívio de tensões não promoveu mudanças significativas nas propriedades.

    cartouches de combustible faiblement enrichi consistent ordinairement en un element d'uranium gaine d'aluminium, de zirconium ou d'acier inoxydable et donnent lieu a deux sortes de dechets. Les uns sont des dechets a activite moyenne contenant environ 0,1% de produits de fission et proviennent de la dissolution chimique. Les autres sont des dechets a activite elevee contenant tous les autres produits de fission dans une solution d'acide nitrique etendue. Le volume des dechets condenses varie de 0,8 litre par kilogramme d'uranium pour les combustibles peu enrichis a 500 litres par kilogramme d'uranium pour les combustibles fortement enrichis, le volume de l'ensemble des dechets d'intensite elevee et intermediaire qui, a ce que l'on prevoit, proviendront des centrales nucleaires aux Etats-Unis. est d'environ 5 litres par kilogramme d'uranium en moyenne. Aux Etats-Unis, on estime qu'en 1970, les centrales nucleaires auront produit environ 3 milliards de curies contenues dans 27 millions de litres de solution, et en l'an 2000, 60 milliards de curies contenues dans 1,1 milliard de litres de solution.

Sin embargo, a diferencia de lo que sucede en el contexto nacional, entre las mujeres y hombres jóvenes en Chiapas observamos el predominio de una sexualidad estrechamente vinculada a la unión conyugal. En este contexto, acudir con trabajadoras del sexo comercial (TSC parece constituirse en la única opción de los varones jóvenes para tener relaciones sexuales antes y fuera del matrimonio. En una investigación cualitativa realizada con jóvenes de entre 15 y 19 años de edad, residentes de tres municipios de la región fronteriza, analizamos las condiciones que permiten la no ocurrencia de un patrón que distinga claramente la iniciación sexual de la vida en pareja, como está documentado en el ámbito nacional.

    The magnetic properties of two U(Ni 1-x Cu x ) 2 Si 2 solid in the vicinity of x = 0.50 (denoted I and II) have been studied by neutron diffraction and ac-susceptibility. Both materials have ThCr 2 Si 2 -type crystallographic structure. AC-susceptibility shows antiferromagnetic transitions at T N 150±5 K in UNiCuSi 2 (I) and 155±5 K in UNiCuSi 2 (II), followed by several transitions with ferrimagnetic (F) character at lower temperatures. Apart from the transitions to AF-I structure at T N =150K and 152K none of the F transitions is observed by neutron diffraction. Short-range magnetic order, involving several consecutive ferromagnetic planes or ferrimagnetic groups of planes in the AF-I phase, detected by ac-susceptibility and not by neutron diffraction in both materials and therefore significant to x ∼ 0.50, is proposed to explain the unusual susceptibility.

    The experimental (e,2e) coincidence spectroscopy, known as electron momentum spectroscopy (EMS) was applied to the trans 1,3 butadiene (C{sub 4}H{sub 6}) molecule with detailed binding energy spectra and orbital momentum distributions (MDs) being measured. A small selection of this data is presented. The usage of UniChem computational chemistry codes for the Flinders-developed AMOLD program allows to calculate theoretical MDs for each orbital, to help elucidate the valence electronic structure of butadiene. The results of the many-body Green`s function calculation is also presented, to the ADC(3) level, for the binding energies and spectroscopic factors of the respective orbitals of C{sub 4}H{sub 6}. A critical comparison between the experimental and theoretical MDs allows to determine the optimum wavefunction from the basis sets studied. The determination of the wavefunction then allows to make further use of the UniChem package to derive butadiene`s chemically interesting molecular properties. A summary of these results and comparison of them with the previous results of other workers is presented. 23 refs., 2 tabs., 2 figs.

    About 40 years ago interest in the measurement of elongational viscosity of polymer melts started to grow. Here we present measurements of transient (and steady) uni-axial elongational viscosity, using the FSR, of the following melts: Four narrow MMD polystyrene (PS) samples with weight......-average molar mass Mw in the range of 50k to 390k. Three different bi-disperse samples, mixed from the narrow MMD PS. Two low-density polyethylene (LDPE) melts (Lupolen 1840D and 3020D). A steady-state viscosity was kept for 1-2.5 Hencky strain units in all measurements.The measurements on the bi-disperse PS...... melts have demonstrated that both the transient and steady elongational viscosity is quite sensitive to polydispersity. Bi-disperse PS resembles the behaviour of mono-disperse melts only at elongational rates larger then the inverse of maximal time constant of the smallest molecule. As observed in Boger...

    Full Text Available Pode-se verificar, desde o final da década de 1990, uma tendência de institucionalização da condicionalidade política em diversas instituições internacionais. Estas instituições têm tornado explícita a importância do respeito, por parte dos Estados participantes, ao Estado de direito, aos direitos humanos e à democracia; têm também criado mecanismos de controle, supervisão e promoção destes princípios. A forma como tais princípios têm sido institucionalizados, os instrumentos disponíveis para garantir sua aquiescência, a aquiescência efetiva e seu efeito sobre os Estados-membros variam de acordo com cada instituição. Este artigo analisa o caso da União Européia. Apesar do consenso sobre os valores democráticos entre seus membros fundadores, foi somente em 1997, com o Tratado de Amsterdã, que eles se tornaram uma condição formal para a participação no processo de integração. O presente artigo procura responder, primeiramente, como, e por que, a condicionalidade política tem sido institucionalizada na União Européia, explorando dois fatores em particular: 1 o processo de ampliação do processo de integração e 2 crises políticas específicas que ocorreram nos Estados-membros. Adicionalmente, o artigo indaga se a condicionalidade pode ser considerada um instrumento efetivo de promoção da democracia. Busca-se analisar se a intervenção a favor da democracia tem um efeito qualitativo sobre os regimes domésticos, ou seja, explora-se os limites do uso da condicionalidade política como um instrumento de promoção e defesa da democracia.Promotion Political conditionality has been institutionalized in many international institutions since the end of the 1990s.

    Extraction techniques to extract fish oil from various types of fish are numerous but not widely accepted because of the use of chemicals that may be harmful to health. In this study, fish oil is extracted using a technique of Microwave-Assisted Extraction, which uses only water. The optimum conditions required for the production of fish oil for extraction is carried out by examining three parameters such as microwave power (300-700W), extraction time (10-30 min) and amount of water used (70-190ml). Optimum conditions were determined after using design of experiments (DOE). The optimum condition obtained was 300 W for microwave power, 10 minutes extraction time and 190 milliliter amounts of water used. Fourier transform infrared spectroscopy (FTIR) was used to analyze the functional groups of fish oil. Two types of fish such as Jade Perch or UniMAP Puyu and Indian Mackerel were used. A standard omega-3 oil sample (Blackmores) purchased from pharmacy was also determined to confirm the presence of omega-3 oil in these fishes. Similar compounds were present in Jade Perch and Indian Mackerel as compared to the standard. Therefore, there were presence of omega-3 fish oil in the two types of fish. From this study, omega-3 in UniMAP Puyu fish was higher compared to Indian Mackerel fish. However, based on the FTIR analysis, besides the presence of omega-3, the two fishes also contain other functional groups such as alkanes, alkenes, aldehyde, ketones and many others. The yield of fish oil for the Jade Perch was low compared to Indian Mackerel which was 9% while Indian Mackerel was 10 %.

    Full Text Available En este artículo se efectúa un análisis de la integración y dependencia de las políticas monetarias de la Unión Europea y, en concreto, de las políticas monetarias de la Unión Económica yMonetaria y de la zona no euro para el periodo comprendido entre Enero de 1999 y Septiembre 2009. Se aplica la metodología de la cointegración de Engle y Granger (1987 y de Johansen(1988 para contrastar la hipótesis de la paridad de tipos de interés no cubierta y se llega a la conclusión de que ambas políticas están cointegradas porque mantienen una relación de equilibrio a largo plazo. También se deduce una dependencia de la política del Banco de Inglaterra de la política del Banco Central Europeo, lo que confirma la importancia y el liderazgo de la Unión Económica y Monetaria.This study is to investigate the long-run relationship and dependence between the UME´s monetary policy and non-euro zone´s monetary policy for the period from January 4, 1999 to September 30, 2009. We use cointegration methodology to test the Uncovered Interest Parity Hypothesis and the results indicate a long-run cointegration and empirical evidence testifies a leader-follower pattern between the two central banks. According to this pattern, the Bank of England does follow the European Central Bank.

  20. Ultrahigh-sensitive detection of molecules produced in catalytic reactions by uni-atomic-composition bi-element clusters supported on solid substrate

    Yasumatsu, H; Fukui, N

    2013-01-01

    An apparatus has been developed for measuring catalytic activities of uni-atomic-composition bi-element clusters supported on a solid substrate. The cluster sample is prepared by irradiating a cluster-ion beam having the uni-atomic composition onto the substrate on a soft-landing condition in an ultra-high vacuum. The catalytic activity is measured by temperature-programmed desorption (TPD) mass analysis. Molecules at a density as low as 3 cm −3 have been detected with an ultrahigh-sensitive TPD mass spectrometer consisting of a cylindrical electron gun, a quadrupole mass filter and a micro-channel-plate ion-detector. The high reproducibility has been achieved by careful calibration of the TPD mass spectrometer. As a benchmark example, thermal oxidation of CO catalysed on Pt 30 disks supported on a silicon surface was studied. The CO 2 products have been successfully observed at the Pt 30 density as low as 3 × 10 12 clusters in a circular area of 8 mm in diameter at the ramping rate of the sample temperature as low as 0.3 K s −1 .

    Ga and Pt NMR measurements have been carried out for two isomorphs compounds, UPtGa sub 5 and UNiGa sub 5 , which exhibit different magnetic structures below T sub N. Knight shift K measurements in the paramagnetic region are reported here. The transferred hyperfine coupling constants at Ga and Pt sites are determined. The temperature independent part K sub 0 of K, which probes the conduction electron polarization at the ligand site, has been successfully evaluated. A nearly identical conduction electron structure in the paramagnetic region is suggested for these two compounds. The origin of the different magnetic structures is discussed.

    2017-12-01

    Parameter calibration has been demonstrated as an effective way to improve the performance of dynamic models, such as hydrological models, land surface models, weather and climate models etc. Traditional optimization algorithms usually cost a huge number of model evaluations, making dynamic model calibration very difficult, or even computationally prohibitive. With the help of a serious of recently developed adaptive surrogate-modelling based optimization methods: uni-objective optimization method ASMO, multi-objective optimization method MO-ASMO, and probability distribution estimation method ASMO-PODE, the number of model evaluations can be significantly reduced to several hundreds, making it possible to calibrate very expensive dynamic models, such as regional high resolution land surface models, weather forecast models such as WRF, and intermediate complexity earth system models such as LOVECLIM. This presentation provides a brief introduction to the common framework of adaptive surrogate-based optimization algorithms of ASMO, MO-ASMO and ASMO-PODE, a case study of Common Land Model (CoLM) calibration in Heihe river basin in Northwest China, and an outlook of the potential applications of the surrogate-based optimization methods.

  12. Transitions of interaction outcomes in a uni-directional consumer-resource system

    Wang, Y.; DeAngelis, D.L.

    2011-01-01

    A uni-directional consumer-resource system of two species is analyzed. Our aim is to understand the mechanisms that determine how the interaction outcomes depend on the context of the interaction; that is, on the model parameters. The dynamic behavior of the model is described and, in particular, it is demonstrated that no periodic orbits exist. Then the parameter (factor) space is shown to be divided into four regions, which correspond to the four forms of interaction outcomes; i.e. mutualism, commensalism, parasitism and amensalism. It is shown that the interaction outcomes of the system transition smoothly among these four forms when the parameters of the system are varied continuously. Varying each parameter individually or varying pairs of parameters can also lead to smooth transitions between the interaction outcomes. The analysis leads to both conditions for which each species achieves its maximal density, and situations in which periodic oscillations of the interaction outcomes emerge. ?? 2011 Elsevier Ltd.

    Because the visual cortices are contra-laterally organized, inter-hemispheric transfer tasks have been used to behaviorally probe how information briefly presented to one hemisphere of the visual cortex is integrated with responses resulting from the ipsi- or contra-lateral motor cortex. By forcing rapid information exchange across diverse regions, these tasks robustly activate not only gray matter regions, but also white matter tracts. It is likely that the response hand itself (dominant or non-dominant) modulates gray and white matter activations during within and inter-hemispheric transfer. Yet the role of uni-manual responses and/or right hand dominance in modulating brain activations during such basic tasks is unclear. Here we investigated how uni-manual responses with either hand modulated activations during a basic visuo-motor task (the established Poffenberger paradigm) alternating between inter- and within-hemispheric transfer conditions. In a large sample of strongly right-handed adults (n = 49), we used a factorial combination of transfer condition [Inter vs. Within] and response hand [Dominant(Right) vs. Non-Dominant (Left)] to discover fMRI-based activations in gray matter, and in narrowly defined white matter tracts. These tracts were identified using a priori probabilistic white matter atlases. Uni-manual responses with the right hand strongly modulated activations in gray matter, and notably in white matter. Furthermore, when responding with the left hand, activations during inter-hemispheric transfer were strongly predicted by the degree of right-hand dominance, with increased right-handedness predicting decreased fMRI activation. Finally, increasing age within the middle-aged sample was associated with a decrease in activations. These results provide novel evidence of complex relationships between uni-manual responses in right-handed subjects, and activations during within- and inter-hemispheric transfer suggest that the organization of the

    Piezoresistive pressure sensors with a twin-island structure were successfully fabricated using high quality Uni-bond-SOI (On Insulator) materials. Since the piezoresistors were structured by the single crystalline silicon overlayer of the SOI wafer and were totally isolated by the buried SiO 2 , the sensors are radiation-hard. The sensitivity and the linearity of the pressure sensors keep their original values after being irradiated by 60 Co γ-rays up to 2.3 x 10 4 Gy(H 2 O). However, the offset voltage of the sensor has a slight drift, increasing with the radiation dose. The absolute value of the offset voltage deviation depends on the pressure sensor itself. For comparison, corresponding polysilicon pressure sensors were fabricated using the similar process and irradiated at the same condition

La expansión del Estado Islámico (ISIS ha incrementado el flujo de europeos que viajan a Siria e Irak para unirse a sus filas. Al menos, 30.000 combatientes procedentes de todo el mundo han hecho ya este trayecto para luchar bajo las órdenes del autoproclamado "califato". A falta de una política común, los Gobiernos de los países miembros de la Unión Europea intentan coordinar medidas de contraterrorismo.

    The authors used gamma cardiology during the abatement of 16 cases of asthma with a view to detecting heart attacks not otherwise visible with routine methods of examination: clinical, radiological and electro-cardio-graphical. In gamma cardiology, a radioactive indicator is used and its path followed in the cavities of the heart. The method makes it possible to study the circulation in the right heart, the pulmonary crossing, and the left heart, as well as evaluation of the heart-flow. As a result of their investigations the authors, after having discussed the significance of the data obtained with the method, suggest that it is possible by the use of gamma cardiography during the abatement of an asthma attack: 1- To confirm attacks of the right heart which have already been detected by ordinary methods. 2- To confirm the presence of modifications in the recorded curves which suggest, in the case of the left heart, possible attack; such on attack is also indicated, in a small number of cases, by electrocardiography curves. Some considerations are put forward by the authors concerning the physiopathology of attacks on the left heart.

    Purpose: Fluoroscopically guided transcervical fallopian tube recanalization is recognized as an important step in the workup of female infertility. In the present study, a simplified set of recanalization instruments was tested. Materials and Methods: Forty-two women with infertility and sonographically confirmed or suspected uni- or bilateral tubal occlusion were examined. After vaginal placement of a plastic speculum and fixation of a tenaculum, a 4F glide catheter with a 0.89 mm glidewire was advanced transcervically. After documentation of tubal occlusion by hysterosalpingography, the uterotubal junction was catheterized with the same instruments. Under fluoroscopic guidance, the glidewire was negotiated beyond the intramural portion of the tube. Selective salpingography documented the outcome of the recanalization. Results: Hysterosalpingography confirmed tubal occlusions in 26 of 42 patients (in 12 cases unilateral and in 14 cases bilateral). Fallopian tube recanalization was successful in 23 of 26 patients (technical success rate of 88%). The resulting fertility rate was 30% (7/23), without any ectopic pregnancy. Complications such as tubal perforation, infection, or bleeding did not occur. Tubal catheterization was straightforward and smooth in 17/23 cases. For a hyperflexed uterus (6/23), a curved tip of the catheter was helpful in tubal probing. (orig.)

    The optical vibrations of hydrogen in TbNiAlH sub 1 sub . sub 4 and UNiAlH sub 2 sub . sub 0 were investigated by means of inelastic neutron scattering. The experimental data were analysed, including multiphonon neutron scattering contributions, calculated in an isotropic harmonic approximation. At least two fundamental H optical peaks were observed in TbNiAlH sub 1 sub . sub 4 , and were assigned to the vibrational modes of hydrogen atoms occupying different interstitial sites in the metal sublattice. The high-energy part of the UNiAlH sub 2 sub . sub 0 spectra is characterized by strong anharmonicity, and a broad fundamental band. The latter can be accounted for by a large dispersion of phonon modes due to the strong H-H interactions, and/or different metal-hydrogen force constants, which may originate from different metal atoms surrounding the H atoms in the unit cell.

    This study evaluates the effect of variation in the ambient moisture on the compaction behavior of microcrystalline cellulose (MCC) powder. The study was conducted by comparing the physico-mechanical properties of, and the near infrared (NIR) spectra collected on, compacts prepared by roller compaction with those collected on simulated ribbons, that is, compacts prepared under uni-axial compression. Relative density, moisture content, tensile strength (TS), and Young modulus were used as key sample attributes for comparison. Samples prepared at constant roller compactor settings and feed mass showed constant density and a decrease in TS with increasing moisture content. Compacts prepared under uni-axial compression at constant pressure and compact mass showed the opposite effect, that is, density increased while TS remained almost constant with increasing moisture content. This suggests difference in the influence of moisture on the material under roller compaction, in which the roll gap (i.e., thickness and therefore density) remains almost constant, vs. under uni-axial compression, in which the thickness is free to change in response to the applied pressure. Key sample attributes were also related to the NIR spectra using multivariate data analysis by the partial least squares projection to latent structures (PLS). Good agreement was observed between the measured and the NIR-PLS predicted values for all key attributes for both, the roller compacted samples as well as the simulated ribbons.

  1. Multi-Level Pre-Correlation RFI Flagging for Real-Time Implementation on UniBoard

    2016-03-01

    Because of the denser active use of the spectrum, and because of radio telescopes higher sensitivity, radio frequency interference (RFI) mitigation has become a sensitive topic for current and future radio telescope designs. Even if quite sophisticated approaches have been proposed in the recent years, the majority of RFI mitigation operational procedures are based on post-correlation corrupted data flagging. Moreover, given the huge amount of data delivered by current and next generation radio telescopes, all these RFI detection procedures have to be at least automatic and, if possible, real-time. In this paper, the implementation of a real-time pre-correlation RFI detection and flagging procedure into generic high-performance computing platforms based on field programmable gate arrays (FPGA) is described, simulated and tested. One of these boards, UniBoard, developed under a Joint Research Activity in the RadioNet FP7 European programme is based on eight FPGAs interconnected by a high speed transceiver mesh. It provides up to 4 TMACs with ®Altera Stratix IV FPGA and 160 Gbps data rate for the input data stream. The proposed concept is to continuously monitor the data quality at different stages in the digital preprocessing pipeline between the antennas and the correlator, at the station level and the core level. In this way, the detectors are applied at stages where different time-frequency resolutions can be achieved and where the interference-to-noise ratio (INR) is maximum right before any dilution of RFI characteristics by subsequent channelizations or signal recombinations. The detection decisions could be linked to a RFI statistics database or could be attached to the data for later stage flagging. Considering the high in-out data rate in the pre-correlation stages, only real-time and go-through detectors (i.e. no iterative processing) can be implemented. In this paper, a real-time and adaptive detection scheme is described. An ongoing case study has been

    In recent years, many research works from institutions that participated in Formula SAE had highlighted on suspension systems. The aim is to improve the system in term of performance and robustness. However, every suspension system for a racing car is tailored to the car itself. Thus, this paper proposes a new design for front suspension system for UniART FSAE car. The new design was than being compared to the previous suspension system for enhancement. The analysis covered in this paper based on several conditions such as braking, cornering and bumping condition and was carried out using finite element analysis. Each main component for the suspension system such as lower arm, upper arm and knuckle has been analysed in term of strength and performance. From the results, the proposed new design of the suspension system has improved in term of strength and performance compared to the previous suspension system.

However, while in France, the film investment schemes and Canal Plus Group’s established position as a major source of finance led to the shortening of release windows but not to the disappearance of the release windows format, in the United States, the declining DVD sales and revenues forced the major studios to study new methods of distribution and new business models, based on day-and-date releases and on the gradual dissolution of the windows model.

    In many laboratories the number of measured routine gamma-spectra can be significant and the labour work to review all the data is time consuming and expensive task. In many cases the routine sample does not normally contain radiation above a detectable level, and still the review of the spectra has to be performed. By introducing simple rules for emerging conditions, the review work can be significantly reduced. In one case the need to review the environmental measurement spectra was reduced to less than 1% compared to the original need, which in turn made the review personnel available for more useful functions. Using the UniSampo analysis system, the analysis results of spectra that are causing alarming conditions can be transmitted via e-mail to any address. Some systems are even equipped with the capability to forward these results to hand-portable telephones or pagers. This is a very practical solution for automated environmental monitoring, when the sample spectra are collected automatically and transmitted to central computer for further analysis. Set up of an automatic analysis system, rules for the emerging conditions, technical solutions for an automated alarming system and a generic hypothesis test for the alarming system developed for UniSampo analysis software are described.

    Knee arthroplasty is a successful standard procedure in orthopedic surgery; however, approximately 20 % of patients are dissatisfied with the clinical results as they suffer pain and can no longer achieve the presurgery level of activity. According to the literature the reasons are inexact fitting of the prosthesis or too few anatomically formed implants resulting in less physiological kinematics of the knee joint. Reducing the number of dissatisfied patients and the corresponding number of revisions is an important goal considering the increasing need for artificial joints. In this context, patient-specific knee implants are an obvious alternative to conventional implants. For the first time implants are now matched to the individual bone and not vice versa to achieve the best possible individual situation and geometry and more structures (e.g. ligaments and bone) are preserved or only those structures are replaced which were actually destroyed by arthrosis. According to the authors view, this represents an optimal and pioneering addition to conventional implants. Patient-specific implants and the instruments needed for correct alignment and fitting can be manufactured by virtual 3D reconstruction and 3D printing based on computed tomography (CT) scans. The portfolio covers medial as well as lateral unicondylar implants, medial as well as lateral bicompartmental implants (femorotibial and patellofemoral compartments) and cruciate ligament-preserving as well as cruciate ligament-substituting total knee replacements; however, it must be explicitly emphasized that the literature is sparse and no long-term data are available.

    The Camagüey district, Cuba, is known for its epithermal precious metal deposits in a Cretaceous volcanic arc setting. Recently, the La Unión prospect was discovered in the southern part of the district, containing gold and minor copper mineralization interpreted as porphyry type. Mineralization is hosted in a 73.0 ± 1.5 Ma calc-alkaline I-type oxidized porphyry quartz diorite intrusive within volcanic and volcaniclastic rocks of the early Cretaceous Guáimaro Formation. The porphyry is affected by propylitic alteration and crosscut by a network of quartz and carbonate veinlets and veins. Chlorite, epidote, sericite, quartz, and pyrite are the main minerals in the early veins which are cut by late carbonate and zeolite veins. Late barite pseudomorphously replaces pyrite. Gold is associated with pyrite as disseminations in the altered quartz diorite and in the veins, occurring as inclusions or filling fractures in pyrite with 4 g/t Au in bulk samples, and up to 900 ppm Au in in pyrite. Fluid inclusion and oxygen isotope data are consistent with a H2O-NaCl-(KCl) mineralizing fluid, derived from the quartz diorite magma, and trapped at least at 425°C and 1.2 kbar. This primary fluid unmixed into two fluid phases, a hypersaline aqueous fluid and a low-salinity vapor-rich fluid. Boiling during cooling may have played an important role in metal precipitation. Pyrite δ34S values for the La Unión prospect range between 0.71‰ and 1.31‰, consistent with a homogeneous magmatic sulfur source. The fluids in equilibrium with the mineralized rocks have estimated δ18O values from 8‰ to 11.8‰, calculated for a temperature range of 480-505°C. The tectonic environment of the La Unión prospect, its high gold and low copper contents, the physical-chemical characteristics of the mineralizing fluids and the isotopic signature of the alteration minerals and fluids indicate that the La Unión gold mineralization is similar to the porphyry gold type, even though the ore

Sugere-se que alguns tratamentos da superfície dentinária podem favorecer esse processo de adesão. Objetivo Avaliar os efeitos de diferentes tratamentos, em superfície dentinária plana condicionada, sobre a resistência de união à microtração de sistemas adesivos do tipo “condiciona-e-lava” de dois passos. Material e método Noventa e seis terceiros molares humanos foram divididos em 12 grupos (n=8, aleatoriamente, de acordo com o sistema adesivo utilizado (GI: Adper Single Bond 2 - 3M ESPE; GII: Prime & Bond 2.1 - Dentsply; GIII: Excite - Ivoclar Vivadent e o tipo de tratamento do substrato dentinário condicionado (a: água; b: clorexidina + água; c: etanol; d: clorexidina + etanol. Todos os dentes foram restaurados com resina Charisma na cor A2 (Heraeus - Kulzer, Germany e submetidos a ensaio mecânico de microtração (EMIC DL-2000. O teste estatístico realizado foi ANOVA a um fator, completado com teste de Tukey. Resultado Os grupos GIIc, GIIIc e GIId apresentaram aumento significativo estatisticamente na resistência de união à microtração imediata. Conclusão Os diferentes tratamentos da dentina condicionada não afetaram de maneira negativa a resistência de união para todos os sistemas adesivos testados e a utilização da técnica com etanol, associado ou não à clorexidina, parece ser uma interessante abordagem quando associada a sistemas adesivos “condiciona-e-lava” de dois passos.

    This presentation described specialty fluid packages for modeling oil and gas process systems involving sour gases in contact with aqueous phase. UniSim Design is a popular process simulation tool in the oil and gas industry. The sour Peng-Robinson (PR) and sour Soave-Redlich-Kwong (SRK) models are commonly used for handling sour system where hydrogen sulphide (H{sub 2}S), carbon dioxide (CO{sub 2}) or ammonia (NH{sub 3}) are in contact with an aqueous phase. These sour options combine the PR/SRK equation of state and Wilson's API-sour model where the equation of state is used to determine the fugacities of the vapor and liquid hydrocarbon phases, plus the enthalpy for all 3 phases. The Wilson's API-sour method is used for the aqueous phase calculations, which accounts for the ionization of H{sub 2}S, CO{sub 2} and NH{sub 3} in the aqueous phase. The efficiency of these 2 thermodynamic property packages were evaluated in this study by comparing industrial and experimental data and the results from other similar models. The purpose of this study was to improve these property packages for more accurate and reliable modeling of sour systems. tabs., figs.

    2014-01-01

    In this work neutronic and thermal-hydraulic analyses were made to compare three types of targets (UAl 2 -Al, U-Ni cylindrical and U-Ni plate) used for the production of 99 Mo by fission of 235 U. Some experiments were conducted to validate the neutronic and thermal-hydraulics methodologies used in this work. For the neutronic calculations the computational programs NJOY99.0, AMPX-II and HAMMERTECHNION were used to generate the cross sections. SCALE 6.0 and CITATION computational programs were used for three-dimensional calculations of the reactor cores, fuel burning and the production of 99 Mo. The computational programs MTRCR-IEAR1 and ANSYS CFX were used to calculate the thermal and hydraulic parameters of the irradiation devices and for comparing them to limits and design criteria. First were performed neutronic and thermal-hydraulic analyzes for the reactor IEA-R1 with the targets of UAl 2 -Al (10 mini plates). Analyses have shown that the total activity obtained for 99 Mo on the mini plates does not meet the demand of Brazilian hospitals (450 Ci/week) and that no limit of thermo-hydraulic design is overtaken. Next, the same calculations were performed for the three target types in Multipurpose Brazilian Reactor (MBR). The neutronic analyzes demonstrated that the three targets meet the demand of Brazilian hospitals. The thermal hydraulic analysis shows that a minimum speed of 7 m/s for the target UAl 2 -Al, 8 m/s for the cylindrical target U-Ni and 9 m/s for the target U-Ni plate will be necessary in the irradiation device to not exceed the design limits. Were performed experiments using a test bench for validate the methodologies for the thermal-hydraulic calculation. The experiments performed to validate the neutronic calculations were made in the reactor IPEN/MB-01. All experiments were simulated with the methodologies described above and the results compared. The simulations results showed good agreement with experimental results. (author)

    Full Text Available Au cours du dernier demi-siècle, aucune personnalité n’a été admirée avec autant de constance par ses concitoyens Américains que le Révérend Billy Graham. Démocrate, on l’associe pourtant plus volontiers à deux présidents républicains : Richard M. Nixon et George W. Bush. La présidence de Nixon fut sanctifiée par les conseils spirituels que Graham prodiguait ouvertement (mais aussi par ses conseils politiques plus confidentiels. Quant à George W. Bush, il incarne le fils prodigue : c’est l’ivrogne, le vaurien que Graham a réussi à rediriger vers le Christ, rendant ainsi possible son étonnante ascension politique. Le fort impact de cet évangéliste sur la politique des Etats-Unis et le fait que Graham soit si intimement associé aux deux présidents les plus controversés des cinquante dernières années seront au centre de notre réflexion.

  1. Neutronic and thermal-hydraulic analysis of devices for irradiation of LEU targets type of UAL{sub x}-Al and U-Ni to production of {sup 99}Mo in reactor IEA-R1 and RMB; Analises neutronicas e termo-hidraulica de dispositivos para irradiacao de alvos tipo LEU de UAL{sub x}-Al e U-Ni para producao de {sup 99}Mo nos reatores IEA-R1 e RMB

    In this work neutronic and thermal-hydraulic analyses were made to compare three types of targets (UAl{sub 2}-Al, U-Ni cylindrical and U-Ni plate) used for the production of {sup 99}Mo by fission of {sup 235}U. Some experiments were conducted to validate the neutronic and thermal-hydraulics methodologies used in this work. For the neutronic calculations the computational programs NJOY99.0, AMPX-II and HAMMERTECHNION were used to generate the cross sections. SCALE 6.0 and CITATION computational programs were used for three-dimensional calculations of the reactor cores, fuel burning and the production of {sup 99}Mo. The computational programs MTRCR-IEAR1 and ANSYS CFX were used to calculate the thermal and hydraulic parameters of the irradiation devices and for comparing them to limits and design criteria. First were performed neutronic and thermal-hydraulic analyzes for the reactor IEA-R1 with the targets of UAl{sub 2}-Al (10 mini plates). Analyses have shown that the total activity obtained for {sup 99}Mo on the mini plates does not meet the demand of Brazilian hospitals (450 Ci/week) and that no limit of thermo-hydraulic design is overtaken. Next, the same calculations were performed for the three target types in Multipurpose Brazilian Reactor (MBR). The neutronic analyzes demonstrated that the three targets meet the demand of Brazilian hospitals. The thermal hydraulic analysis shows that a minimum speed of 7 m/s for the target UAl{sub 2}-Al, 8 m/s for the cylindrical target U-Ni and 9 m/s for the target U-Ni plate will be necessary in the irradiation device to not exceed the design limits. Were performed experiments using a test bench for validate the methodologies for the thermal-hydraulic calculation. The experiments performed to validate the neutronic calculations were made in the reactor IPEN/MB-01. All experiments were simulated with the methodologies described above and the results compared. The simulations results showed good agreement with experimental

    SCK-CEN's research and development programme on instrumentation involves the assessment and the development of sensitive measurement systems used within a radiation environment. Particular emphasis is on the assessment of optical fibre components and their adaptability to radiation environments. The evaluation of ageing processes of instrumentation in fission plants, the development of specific data evaluation strategies to compensate for ageing induced degradation of sensors and cable performance form part of these activities. In 2000, particular emphasis was on in-core reactor instrumentation applied to fusion, accelerator driven and water-cooled fission reactors. This involved the development of high performance instrumentation for irradiation experiments in the BR2 reactor in support of new instrumentation needs for MYRRHA, and for diagnostic systems for the ITER reactor.

    Full Text Available Breaking with the traditional conservatism championed by Ronald Reagan, George W. Bush wanted his social policy to move away from monetary considerations to embrace a religious and spiritual method in healing social ills. The Office of Faith-Based and Community Initiatives, located in the White House, was inaugurated a few days after Bush was sworn in. However, the Office was immediately plagued by internal strife, lack of funding and absence of political commitment. Hurricane Katrina (2005 dealt a serious political blow to the Republican President. But paradoxically, it reinforced the ideological hegemony of faith-based organizations. Indeed, following the relief efforts, faith-based organizations, rather than government, were hailed as effective instruments in the fight against poverty, distress, and deviance. This article will argue that contrary to this perception, faith-based organizations have a limited effect on poverty and that the Bush administration exploited them for political purposes.

  6. Processamento de Ligas de Níquel com Técnica de Manufatura Aditiva Utilizando Plasma por Arco Transferido

    Full Text Available ResumoA manufatura aditiva é um processo utilizado para a construção e reparos de peças que possuem geometria complexa ou que necessitem de gradiente de propriedades. Nessa técnica múltiplas camadas são depositadas para a construção da geometria do componente. O sucesso desse procedimento depende de fatores como a técnica de deposição, parâmetros, liga a ser depositada e condições da deposição, como temperatura e atmosfera protetora. Neste estudo, o potencial da técnica de Plasma por arco transferido para manufatura aditiva foi avaliado produzindo “paredes finas”, construídas a partir da sobreposição de cordões. Foram utilizadas duas ligas a base de níquel, uma endurecida por precipitação e outra endurecida por solução sólida. Durante os trabalhos, foram selecionados os parâmetros de processamentos, incluindo a avaliação do efeito do pré-aquecimento a 300°C. Resultados mostraram que a composição química da liga influencia a geometria da parede construída assim como a utilização de pré-aquecimento. Estruturas de solidificação exibindo dendritas refinadas com crescimento epitaxial entre camadas são identificadas. Entretanto, as características da liga determinam o perfil de dureza ao longo da seção transversal, sendo a liga endurecida por precipitação influenciada pelos ciclos térmicos de deposição e a liga endurecida por solução sólida pela diluição com o substrato. Em qualquer dos casos é recomendado a aplicação de tratamento térmico pós-soldagem para uniformização das propriedades.

    Full Text Available Una de las formas de regulación de la actividad de ciertas citocinas es la generación de formas solubles del receptor, las cuales actúan principalmente como proteínas de unión, aunque también se les han atribuido funciones de carácter agonista. El objetivo de este trabajo fue el de establecer la presencia de proteinas de unión a hormona de crecimiento (GHBP y prolactina (PRLBP en suero humano. La GHBP se purificó parcialmente mediante un nuevo método empleando hormona humana de crecimieiito (GH, growth hormone humana inmovilizada sobre Sepharosa y su separación y detección se realizó por medio de electroforesis e inmunotransferencia (Western blot, utilizando un anticuerpo dirigido contra el receptor de GH. Los resultados mostraron que la GHBP de suero humano es una mezcla compleja de proteínas con pesos en el rango de 27 a 62 kDa, relacionadas estructuralmente con el receptor de GH y cuyo origen está por determinarse. El suero proveniente de pacientes con cáncer de seno en estados 3 y 4, así como el de embarazo, mostró el mismo perfil de proteínas aunque sus niveles fueron en todos los casos inferiores a la normalidad, siendo los más bajos los de embarazo. En cuanto a la PRLBP, mediante anticuerpos antirreceptor, se identificó una proteina sérica de 150 kDa disociable en dos subunidades de pesos 50 y 30 kDa, consistente con lo informado por otros autores. De acuerdo con el peso establecido y a su incapacidad para unir hGH, se concluyó que no es una forma soluble del receptor y se sugiere que puede ser un anticuerpo antiidiotípico presente en suero humano. No se encontraron diferencias en el perfil ni en el contenido de la PRLBP en los tres tipos de suero analizados. Los resultados obtenidos ponen en evidencia la existencia de una proteina de unión a prolactina relacionada con el receptor de PRL y cuyo origen en humanos está por establecerse.

    1998-01-01

    The Instrument Remote Control (IRC) project ongoing at NASA's Goddard Space Flight Center's (GSFC) Information Systems Center (ISC) supports NASA's mission by defining an adaptive intranet-based framework that provides robust interactive and distributed control and monitoring of remote instruments. An astronomical IRC architecture that combines the platform-independent processing capabilities of Java with the power of Extensible Markup Language (XML) to express hierarchical data in an equally platform-independent, as well as human readable manner, has been developed. This architecture is implemented using a variety of XML support tools and Application Programming Interfaces (API) written in Java. IRC will enable trusted astronomers from around the world to easily access infrared instruments (e.g., telescopes, cameras, and spectrometers) located in remote, inhospitable environments, such as the South Pole, a high Chilean mountaintop, or an airborne observatory aboard a Boeing 747. Using IRC's frameworks, an astronomer or other scientist can easily define the type of onboard instrument, control the instrument remotely, and return monitoring data all through the intranet. The Astronomical Instrument Markup Language (AIML) is the first implementation of the more general Instrument Markup Language (IML). The key aspects of our approach to instrument description and control applies to many domains, from medical instruments to machine assembly lines. The concepts behind AIML apply equally well to the description and control of instruments in general. IRC enables us to apply our techniques to several instruments, preferably from different observatories.

Elle se divise done en deux parties distinctes reliees par des elements techniques communs. Chacune est toutefois d'un interet propre et se suffit a elle-meme. Caracterisation pratique des systemes quantiques. Le calcul quantique exige un tres grand controle des systemes quantiques composes de plusieurs particules, par exemple des atomes confines dans un piege electromagnetique ou des electrons dans un dispositif semi-conducteur. Caracteriser un tel systeme quantique consiste a obtenir de l'information sur l'etat grace a des mesures experimentales. Or, chaque mesure sur le systeme quantique le perturbe et doit done etre effectuee apres avoir reprepare le systeme de facon identique. L'information recherchee est ensuite reconstruite numeriquement a partir de l'ensemble des donnees experimentales. Les experiences effectuees jusqu'a present visaient a reconstruire l'etat quantique complet du systeme, en particulier pour demontrer la capacite de preparer des etats intriques, dans lesquels les particules presentent des correlations non-locales. Or, la procedure de tomographie utilisee actuellement n'est envisageable que pour des systemes composes d'un petit nombre de particules. Il est donc urgent de trouver des methodes de caracterisation pour les systemes de grande taille. Dans cette these, nous proposons deux approches theoriques plus ciblees afin de caracteriser un systeme quantique en n'utilisant qu'un effort experimental et numerique raisonnable. - La premiere consiste a estimer la distance entre l'etat realise en laboratoire et l'etat cible que l'experimentateur voulait preparer. Nous presentons un protocole, dit de certification, demandant moins de ressources que la tomographie et tres efficace pour plusieurs classes d'etats importantes pour l'informatique quantique. - La seconde

Esta “actualización” de la Estrategia tiene un alcance muy limitado y apenas aporta novedades en el tema de la gestión de crisis, manteniendo la falta de precisión y de rigor conceptual de documentos anteriores. El artículo repasa qué se considera una crisis y en qué consiste la gestión de crisis desde una perspectiva académica y estudia el uso que se ha hecho de estos términos en los documentos que han tratado las cuestiones de seguridad y defensa en la Unión Europea. Se comprueba cómo la aproximación desde las Relaciones Internacionales como disciplina tiene poco que ver con el uso y el significado que de estos conceptos se hace en los documentos de la Unión que tienen que ver con la PESD. El Informe, en consecuencia, es una oportunidad perdida para mantener el rigor conceptual y evitar posibles consecuencias perniciosas a las que pudiera conducir esta situación, tanto en el diseño como en la puesta en marcha de instrumentos u operaciones.

    2008-01-01

    A proper measurement of the relevant single and two-phase flow parameters is the basis for the understanding of many complex thermal-hydraulic processes. Reliable instrumentation is therefore necessary for the interaction between analysis and experiment especially in the field of nuclear safety research where postulated accident scenarios have to be simulated in experimental facilities and predicted by complex computer code systems. The so-called conventional instrumentation for the measurement of e. g. pressures, temperatures, pressure differences and single phase flow velocities is still a solid basis for the investigation and interpretation of many phenomena and especially for the understanding of the overall system behavior. Measurement data from such instrumentation still serves in many cases as a database for thermal-hydraulic system codes. However some special instrumentation such as online concentration measurement for boric acid in the water phase or for non-condensibles in steam atmosphere as well as flow visualization techniques were further developed and successfully applied during the recent years. Concerning the modeling needs for advanced thermal-hydraulic codes, significant advances have been accomplished in the last few years in the local instrumentation technology for two-phase flow by the application of new sensor techniques, optical or beam methods and electronic technology. This paper will give insight into the current state of instrumentation technology for safety-related thermohydraulic experiments. Advantages and limitations of some measurement processes and systems will be indicated as well as trends and possibilities for further development.

    Full Text Available La Unión Europea ha decidido involucrarse en la competición internacional por la inmigración altamente cualificada a través de la Directiva Blue Card. No obstante, dos de los tres Estados miembros que quedan fuera de la aplicación de la Directiva han introducido sistemas de puntos, basándose en las experiencias positivas de terceros países en sus resultados para atraer este tipo de inmigración. Esta coexistencia de sistemas alternativos basados en presupuestos diferentes en la Unión Europea nos lleva a plantearnos qué sistema es el más efectivo en su función de atraer inmigración cualificada, y cuáles son los efectos de esta coexistencia en la política de inmigración común. A la vista de estas consideraciones, nos planteamos cuál es realmente el valor añadido de la directiva comunitaria

    Full Text Available El objetivo fue establecer el comportamiento microestructural de una unión disímil de acero inoxidable austenítico AISI 321 y de la aleación A 351 grado HK 40 obtenida por fundición mediante soldadura manual por arco eléctrico y electrodos revestidos del tipo E 309 L-16. La estructura ferrita–austeníta que se forma en la unión del acero con la aleación es resultado del elevado contenido de carbono de la segunda. La baja velocidad de enfriamiento del cordón de soldadura revela ausencia de discontinuidades en el retículo cristalino de la zona afectada térmicamente y atenúa la formación de carburos de cromo del tipo Cr23C6, que puede formar la aleación A 351 grado HK 40 durante la difusión del volumen de fracción en masa del cromo.

    Full Text Available En este trabajo se investigó la presencia de las principales proteínas de unión a IGF-I en tejidos de rata y el tamaño de los complejos formados en cada caso. Mediante análisis de Western ligand blof (WLB y cromatografía de exclusión molecular, se separaron e identificaron cuatro proteínas de unión, correspondientes a las IGFBP-1 a IGFBP-4. En todos los tejidos analizados, se detectó la proteína IGFBP-3, aunque su concentración varió con el tipo de órgano, siendo muy abundante en hígado, riñón y corazón y escasa en órganos linfoides (timo y bazo. IGFBP-I e IGFBP-2 se identificaron en hígado y pulmón y, además, en corazón y músculo esquelético, órganos donde hasta el momento no se han identificado los correspondientes mARN, como tampoco IGFBP-4, identificada en este trabajo en pulmón. En conclusión, los resultados obtenidos indican un perfil típico para las IGFBP de acuerdo con el tejido, aunque no es claro aún si su presencia es el resultado de su síntesis NI situo de un transporte transcapilar. La identificación de sus mensajeros es un paso esencial para comprender el papel regulador que estas proteínas desempeñan en la biodisponibilidad del IGF-I en los diferentes tejidos.

    Ubbes, W.F.; Yow, J.L. Jr.

    1988-01-01

    Instrumentation is developed for the Civilian Radioactive Waste Management Program to meet several different (and sometimes conflicting) objectives. This paper addresses instrumentation development for data needs that are related either directly or indirectly to a repository site, but does not touch on instrumentation for work with waste forms or other materials. Consequently, this implies a relatively large scale for the measurements, and an in situ setting for instrument performance. In this context, instruments are needed for site characterization to define phenomena, develop models, and obtain parameter values, and for later design and performance confirmation testing in the constructed repository. The former set of applications is more immediate, and is driven by the needs of program design and performance assessment activities. A host of general technical and nontechnical issues have arisen to challenge instrumentation development. Instruments can be classed into geomechanical, geohydrologic, or other specialty categories, but these issues cut across artificial classifications. These issues are outlined. Despite this imposing list of issues, several case histories are cited to evaluate progress in the area

  17. Vision though afocal instruments: generalized magnification and eye-instrument interaction

    Science.gov (United States)

    Harris, William F.; Evans, Tanya

    2018-04-01

    In Gaussian optics all observers experience the same magnification, the instrument's angular magnification, when viewing distant objects though a telescope or other afocal instruments. However, analysis in linear optics shows that this is not necessarily so in the presence of astigmatism. Because astigmatism may distort and rotate images it is appropriate to work with generalized angular magnification represented by a 2 × 2 matrix. An expression is derived for the generalized magnification for an arbitrary eye looking through an arbitrary afocal instrument. With afocal instruments containing astigmatic refracting elements not all eyes experience the same generalized magnification; there is interaction between eye and instrument. Eye-instrument interaction may change as the instrument is rotated about its longitudinal axis, there being no interaction in particular orientations. A simple numerical example is given. For sake of completeness, expressions for generalized magnification are also presented in the case of instruments that are not afocal and objects that are not distant.

    Full Text Available Durante las últimas tres décadas, la participación de la mujer en el mercado de trabajo en Venezuela se ha incrementado significativamente. Durante el mismo periodo, la tasa de disolución de la primera unión ha experimentado importantes incrementos. En este artículo estimamos el efecto del trabajo de la esposa en la disolución de la primera unión. Los datos provienen de una muestra de mujeres de la Región Capital de Venezuela. Los resultados sugieren que el empleo de las esposas después del matrimonio incrementa significativamente el riesgo de divorcio. Tales efectos parecen ser particularmente fuertes durante los primeros cinco años de matrimonio, cuando la probabilidad de divorcio para las esposas con empleo es más de dos veces superior a la probabilidad de divorcio de las que no trabajan en el mercado laboral.

    Full Text Available Factores globales como el crecimiento sostenidon poblacional, el aumento de la demanda mundial de alimentos –particularmente de carne de res– y las restricciones productivas, por la estacionalidad climática, en algunos países del cono sur, como Argentina, Uruguay y Paraguay, hacen prever el aumento de la oferta cárnica bovina de Colombia; sin embargo, esto no es suficiente para que Colombia sea aceptado por la Unión Europea (UE como proveedor internacional de carnes especializadas y de alto valor agregado. En la actualidad, es necesario adoptar medidas que busquen mejorar la competitividad, incrementar los estándares de consumo del mercado interno, promover sistemas productivos alternativos (silvopastoriles, mejorar y mantener el estatus sanitario, garantizar la calidad y consistencia de la oferta de ganados, aplicar prácticas que garanticen el bienestar animal, implementar adecuadamente la trazabilidad, y garantizar la inocuidad, para que finalmente el país obtenga la distinción internacional de productor de carnes limpias, biológicas, orgánicas y de alto valor agregado, mejorando así la rentabilidad del negocio cárnico nacional en cada uno de sus eslabones. Para lograr lo anterior, se busca entender, apropiar y aplicar alternativas comerciales para exportar carne de res a la UE, como la Cuota Hilton, un cupo de aproximadamente 60.250 toneladas de cortes finos de carne de res, con sus respectivas especificaciones, destinado a aquellos países con condiciones productivas y de transformación cárnica como Colombia. La investigación que aquí se presenta buscó diagnosticar la implementación de un modelo comercial para la exportación de cortes finos de carne bovina a la Unión Europea.

    Full Text Available O presente artigo analisa a prática de subsídios à agricultura no comércio internacional, tendo como principal objetivo dimensionar a sua prática enquanto instrumento econômico estratégico para o setor agrícola, especialmente para os Estados Unidos e a União Europeia. Uma completa proibição dos subsídios não é desejável porque sua prática, em essência, constitui uma alternativa à busca do bem-estar social da nação. Contudo, a utilização dos subsídios agrícolas, na forma como vêm sendo praticados, constituem-se em intervenções de cunho protecionista que provocam distorções no comércio internacional. Sendo os Estados Unidos e a União Europeia as nações que mais os utilizam no comércio internacional, tem-se gerado preocupações sobre sua própria eficiência enquanto instrumento de política comercial estratégica para o comércio internacional.This study examines the practice of agricultural subsidies in international trade, aiming at scaling its practice as a strategic economic tool primarily for the agricultural sector, especially to the United States and the European Union. A complete ban on subsidies is not desirable because its practice, in essence, is a path to improve the welfare of the nation. However, the way the agricultural subsidies have been employed, constitute protectionist interventions that distort international trade. The United States and the European Union are the major users of this instrument in international trade, a factor that has raised concerns about their own efficiency as a strategic trade policy for international trade.

    Full Text Available Objectives: The goal of this project was to develop the first disease-specific instrument for the evaluation of quality of life in chronic pancreatitis. Methods: Focus groups and interview sessions were conducted, with chronic pancreatitis patients, to identify items felt to impact quality of life which were subsequently formatted into a paper-and-pencil instrument. This instrument was used to conduct an online survey by an expert panel of pancreatologists to evaluate its content validity. Finally, the modified instrument was presented to patients during precognitive testing interviews to evaluate its clarity and appropriateness. Results: In total, 10 patients were enrolled in the focus groups and interview sessions where they identified 50 items. Once redundant items were removed, the 40 remaining items were made into a paper-and-pencil instrument referred to as the Pancreatitis Quality of Life Instrument. Through the processes of content validation and precognitive testing, the number of items in the instrument was reduced to 24. Conclusions: This marks the development of the first disease-specific instrument to evaluate quality of life in chronic pancreatitis. It includes unique features not found in generic instruments (economic factors, stigma, and spiritual factors. Although this marks a giant step forward, psychometric evaluation is still needed prior to its clinical use.

    Full Text Available El artículo expone la necesidad de acometer el modo en que la Unión Europea viene planteando su modelo de desarrollo cultural en la última década y de cara a un futuro próximo. Partiendo del análisis de los modelos culturales de masas imperantes en las democracias posmodernas, proponemos que las formas de cultura disidentes (minoritarias o minorizadas, precisamente por su condición refractaria al modelo estandarizado de cultura generado por la actual lógica político-económica comunitaria, constituyen una garantía para la posibilidad misma, tras la modernidad, de otra cultura en Europa. En este sentido, hemos ejemplarizado en la producción audiovisual danesa una alternativa a la errática política cultural de la Unión Europea: aunque procedente de un pequeño territorio y soportada por una lengua de implantación geográfica reducida, evidencia una significativa producción fílmica de calidad, cuyas señas inequívocas de identidad la erigen en hecho cultural reconocible e irrenunciable. En contraposición, se analizan algunos de los aspectos más ilustrativos del Plan Europa Creativa, cuyo carácter refractario a la diversidad cultural como modelo denunciamos abiertamente: entre otros, desaparecen los propósitos de planes anteriores con respecto a la VO y el multilingüismo, las pequeñas cinematografías dejan de ser interlocutoras válidas desde el punto de vista comunitario, etc.

    Full Text Available Las actuaciones de desarrollo rural llevadas a cabo en la Unión Europea han adolecido históricamente de una coherencia interna propia y se han ido incorporando al acervo comunitario como respuesta puntual a las necesidades de cada momento. La Política de Desarrollo Rural, que nace como segundo pilar de la PAC tras la aprobación de la Agenda 2000, supuso su formalización como tal pero su diseño, construido por la adicción de medidas dispersas, dista mucho de ser una política internamente construida. La nueva formulación aprobada para 2007-13 la consagra como un apéndice de la PAC, con escasos fondos, con serias incógnitas para su puesta en marcha y desarrollo aunque con una estructura y diseño más lógico y una gestión más simplificada.

Foram testados dois sistemas de eluição; oprimeiro operou com a passagem direta e o segundo com a recirculação do eluente. Em seguida, foram realizados dez ciclos consecutivos de sorção-dessorção em duas colunas de leito fixo, uma regenerada com o eluente H2SO4 (0,1 M e outra com MgSO4/H2SO4 (pH 3, em sistema de recirculação do eluente. As etapas de sorção e dessorção foram realizadas em 30 e 2h, respectivamente, representando 20 dias de uso contínuo da biomassa. Foi observada alta quantidade recuperada de níquel nas etapas de eluição (aproximadamente 95%. Ao finaldo décimo ciclo, verificou-se que a alga Sargassum filipendula continuava apresentando valores elevados da capacidade de remoção de níquel da solução, mostrando-se como alternativa eficiente de tratamento de águas residuárias contendo metais. A regeneração dabiomassa apresentou baixo custo, além de ter facilitado o processo de tratamento que dispensou trocas sucessivas da biomassa.The behavior of seaweed Sargassum filipendula during a removal of nickel from a 50 mg L-1 aqueous solution at pH 3.5 in fixed-bed columns operating in adsorption/desorption cycles was studied. Twoelution systems were tested: the first one operating with the direct passage of eluant, and the second one with the solution recycle. Then, ten consecutive sorption-desorption cycles were investigated in two packed-bed columns; the first column was regenerated with H2SO4 (0.1 M, and the second one with MgSO4/H2SO4 (3.5% in pH 3 in an eluant recycle system. The sorption and desorption stages were carried out for about 30 and 2h, respectively, representing 20 days of continuous use of the biomass. A high quantity of recovered nickelwas observed in the elution stages

Dans le cadre de cette thématique, l’esthétique d’Olds est contextualisée au sein de la poésie postconfessionnelle aux Etats-Unis.After having outlined what I call the Athena complex thematized in Sharon Olds’s poetry, this article attempts to shed some light on the sizeable number of poems Olds has devoted to mother figures as her monstrous depictions of the father have caused criticism of her work to focus exclusively on representations of the father. Within the framework of this subject matter, Olds’s aesthetic is contextualized by the postconfessional trend in American poetry.

    Deficiencies exist in both the performance and the quality of health physics instruments. Recognizing the implications of such deficiencies for the protection of workers and the public, in the early 1980s the DOE and the NRC encouraged the development of a performance standard and established a program to test a series of instruments against criteria in the standard. The purpose of the testing was to establish the practicality of the criteria in the standard, to determine the performance of a cross section of available instruments, and to establish a testing capability. Over 100 instruments were tested, resulting in a practical standard and an understanding of the deficiencies in available instruments. In parallel with the instrument testing, a value-impact study clearly established the benefits of implementing a formal testing program. An ad hoc committee also met several times to establish recommendations for the voluntary implementation of a testing program based on the studies and the performance standard. For several reasons, a formal program did not materialize. Ongoing tests and studies have supported the development of specific instruments and have helped specific clients understand the performance of their instruments. The purpose of this presentation is to trace the history of instrument testing to date and suggest the benefits of a centralized formal program

  18. The corrosion resistance of materials used for the manufacture of ear piercing studs

    Full Text Available Nickel containing alloys have been widely used as substrates for the manufacture of studs used for ear piercing. Unfortunately, nickel has also been related to the development of allergic contact dermatitis caused by skin sensitization due to Ni2+ ions. Nickel ions can be leached out into the body fluids due to corrosion reactions. Defect free coatings are very difficult to produce, and therefore nickel free materials should be used as substrates of ear piercing studs, although the commercial alloys used usually contain this element. In this study, the corrosion resistance of two kinds of commercial studs prepared with nickel containing substrates and a titanium laboratory made stud was determined in a culture medium. The corrosion resistance of the studs was investigated by means of potentiodynamic polarization tests and electrochemical impedance spectroscopy as a function of immersion time in the culture medium. The elements that leached out into the medium due to corrosion reactions were analyzed by instrumental neutron activation analysis. The surfaces of the commercial gold-coated studs were examined by scanning electron microscopy and analyzed by energy dispersive spectroscopy, both before and after exposure to the culture medium. The cytotoxicity of the tested studs was also determined in the culture medium.

    Aleaciones conteniendo níquel se han utilizado como substratos para la fabricación de aretes perforantes para orejas. Desafortunadamente, el níquel ha sido relacionado con el desarrollo de una reacción alérgica conocida como dermatitis de contacto, causada por la sensibilización debido a los iones de Ni2+. Estos iones pueden ser liberados hacia los fluidos corporales debido a las reacciones de corrosión. Los aretes, habitualmente, se revisten con películas de oro. Sin embargo, es muy difícil hacer los revestimientos libres de defectos superficiales. Por lo tanto, materiales sin níquel deber

    Probing the warped side of our Universe with gravitational waves and computer simulations, by Kip Thorne, recipient of the Tomalla Prize for Gravity 2016.   "Probing the warped side of our Universe with gravitational waves and computer simulations" Uni Dufour - Auditorium U300 Friday, 16 September at 6 p.m.   Kip Thorne. (Photo: ©Jon Rou) Abstract: A half century ago, John Wheeler challenged his students and colleagues to explore Geometrodynamics: the nonlinear dynamics of curved spacetime. How does the curvature of spacetime behave when roiled in a storm, like a storm at sea with crashing waves. We tried to explore this, and failed. Success eluded us until two new tools became available: computer simulations, and gravitational wave observations. Thorne will describe what these have begun to teach us, and he will offer a vision for the future of Geometrodynamics.

    Full Text Available La integración europea, más allá de sus dificultades, ha sido y sigue siendo un ejemplo de un proceso de integración exitoso, ha tenido un desarrollo extraordinario y una expansión siempre creciente de adhesión de Estados que se han incorporado al bloque. Conforme a sus objetivos el esquema fue afianzándose y aun cuando ha debido transitar crisis y diversas situaciones difíciles, por primera vez se presenta una situación en la cual uno de sus Estados Miembros, el Reino Unido, ubicado entre los tres más destacados en el aporte presupuestario, decide retirarse de la Unión Europea como resultado de un referéndum. El hecho golpea fuertemente a la cohesión que en su conjunto siempre ha demostrado la Unión y requerirá de un profundo análisis sobre los pasos futuros a fin de evitar situaciones similares o un efecto contagio, sobre todo por sectores nacionalistas que pueden encontrar en el planteo del “exit” encender el debate político. La decisión tiene serias consecuencias para el Estado saliente, el Reino Unido tendrá que utilizar una enorme creatividad y poder de negociación para reubicarse en el nuevo contexto para sus negociaciones internacionales. El presente artículo se busca explicar de algún modo lo ocurrido y las consecuencias de la decisión, así como el mecanismo de negociación a partir de la comunicación de la decisión.

    Gaudreau, Louis

    Nous presentons dans cette these une etude detaillee du moment magnetique intrinseque de l'electron, i.e. le spin electronique, incluant la manipulation quantique coherente des etats de spin de trois electrons couples. A cette fin, nous utilisons des boites quantiques laterales pour confiner les electrons. Ces nano-structures, d'une grandeur autour de 1 pm, permettent de confiner un nombre precis d'electrons de facon controlee, allant jusqu'a zero electrons. Les developpements technologiques et d'ingeniosite durant la derniere decennie ont permis de coupler trois boites quantiques, ainsi l'interaction entre plusieurs electrons confines peut etre controlee comme par exemple le couplage quantique tunnel et l'interaction d'echange entre les spins de chacun d'entre eux. A l'aide de boites quantiques couplees, il est possible de realiser des experiences dans plusieurs domaines de la physique moderne : les etats up et down du spin des electrons confines peuvent etre utilisees comme etats quantiques binaires (qubits) dans le domaine de l'informatique quantique, la non-localite quantique peut etre testee en separant spatialement deux electrons enchevetres, il est possible de creer des 'courants de spin enchevetres' utiles en spintronique, et bien d'autres. La manipulation coherente des etats de spin du systeme a trois electrons se fait de facon purement electrique grace a des pulses a haute frequence qui permettent d'augmenter le couplage entre les electrons et de faire la mesure de l'etat resultant apres la manipulation. Nous utilisons l'interaction hyperfine entre les spins des electrons et ceux des noyaux du cristal dans lequel ils resident pour creer les rotations quantiques entre les etats, notamment les etats |Q +3/2> et (D+1/2>. Les resultats obtenus indiquent un temps de coherence de l'ordre de 10 ns. Ces experiences demontrent un niveau de controle sans precedant de boites quantiques triples et pavent la voie vers des nano-structures plus sophistiquees dans

    Full Text Available The digital reconstruction of the recently discovered Tuscanic temple of Uni in Marzabotto gave the chance to test the application of the Building Information Modeling (BIM process to the combined fields of Archaeology and Engineering. In addition to the traditional historic and archaeological analysis, a new methodology in Experimental Archaeology is proposed; it proved to be original and innovative in the examination of the buried building, taking advantage of technologies focused on the architectural reliability validated by inferred digital models. The peculiar aspect of the research involves the elements at the beginning of the process, which consist of foundations or negative archaeological evidences only, supported by the clues and the rules that can be found in the historic and scientific literature. To better define this distinctive working process, the expression ArchaeoBIM was proposed, which highlights the common BIM matrix used for the data management through one or more analytical models, applied to the peculiar aspects of the Archaeological discipline.

    The Visible Integral-Field Replicable Unit Spectrograph (VIRUS) instrument will be installed at the Hobby-Eberly Telescope† in the near future. The instrument will be housed in two enclosures that are mounted adjacent to the telescope, via the VIRUS Support Structure (VSS). We have designed the enclosures to support and protect the instrument, to enable servicing of the instrument, and to cool the instrument appropriately while not adversely affecting the dome environment. The system uses simple HVAC air handling techniques in conjunction with thermoelectric and standard glycol heat exchangers to provide efficient heat removal. The enclosures also provide power and data transfer to and from each VIRUS unit, liquid nitrogen cooling to the detectors, and environmental monitoring of the instrument and dome environments. In this paper, we describe the design and fabrication of the VIRUS enclosures and their subsystems.

    Westinghouse Hanford Company Project W-211 is responsible for providing the system capabilities to remove radioactive waste from ten double-shell tanks used to store radioactive wastes on the Hanford Site in Richland, Washington. The project is also responsible for measuring tank waste slurry properties prior to injection into pipeline systems, including the Replacement of Cross-Site Transfer System. This report summarizes studies of the appropriateness of the instrumentation specified for use in Project W-211. The instruments were evaluated in a test loop with simulated slurries that covered the range of properties specified in the functional design criteria. The results of the study indicate that the compact nature of the baseline Project W-211 loop does not result in reduced instrumental accuracy resulting from poor flow profile development. Of the baseline instrumentation, the Micromotion densimeter, the Moore Industries thermocouple, the Fischer and Porter magnetic flow meter, and the Red Valve Pressure transducer meet the desired instrumental accuracy. An alternate magnetic flow meter (Yokagawa) gave nearly identical results as the baseline fischer and Porter. The Micromotion flow meter did not meet the desired instrument accuracy but could potentially be calibrated so that it would meet the criteria. The Nametre on-line viscometer did not meet the desired instrumental accuracy and is not recommended as a quantitative instrument although it does provide qualitative information. The recommended minimum set of instrumentation necessary to ensure the slurry meets the Project W-058 acceptance criteria is the Micromotion mass flow meter and delta pressure cells

    1995-05-01

    This article deals with the role of Afrikaner Nationalists who had striven to develop the selfassertiveness of their compatriots by means of promoting Afrikaans. Their attempt was aimed at obtaining an equal position to the deeply-rooted British tradition in Natal. The Co-operative Union (“Saamwerk-Unie" consequently had taken up position in the midst of the language problems. The Union made a deliberate attempt at promoting the development of Afrikaans by means of establishing the first language examinations in Afrikaans. This examination system evoked greater interest with every passing year and resulted in a clash between the Co-operative Union and the South African Language Union. The Language Union, with its Dutch language examinations, was the embodiment of the Dutch influence, while the Co-operative Union promoted Afrikaans at grass roots level. A compromise between the two organisations thus had to be made. A joint Examination Commission was therefore established in 1928. Consequently, the new cultural pattern which had been launched by the Co-operative Union was acknowledged in the ranks of the Afrikaner.
