    Miniaturized chemical analysis systems, also know as 'lab-on-a-chip' devices have been rapidly developing over the last decade. Capillary electrochromatography (CEC), a multidimensional separation technique combining capillary electrophoresis (CE) and liquid chromatography (LC) has been of great interest for chip based applications. Preliminary work has been undertaken to develop vertically aligned carbon nanotubes and photopolymerizable silica solgel as novel stationary phase materials for 'chip CEC' separations. Patterned growth of CNTs in a specific location of the channel has been carried out using a solid phase Fe-Al catalyst as well as a vapor deposited ferrocene catalyst. Characterization of the CNT "forests" was achieved using optical microscopy, secondary electron microscopy, high resolution tunneling electron microscopy and Raman spectroscopy. Proof-of-concept applications were demonstrated using reversed phase CEC separations as well as solid phase extraction of a glycosylated protein using concanavilin A immobilized onto the CNT bed. Photopolymerizable silica solgel materials were developed as stationary phase for microfluidic electrochromatographic separations in disposable polydimethylsiloxane (PDMS) chip devices. Effect on morphology and pore size of gels were studied as function of UV and solgel polymerization conditions, porogen, salt additives, geometry and hydrolyzable methoxy-ies. Structural morphologies were studied with Secondary Electron Microscopy (SEM). Pore size and pore volumes were characterized by thermal porometry, nitrogen BET adsorptions and differential scanning calorimetry. Computational fluid dynamics and confocal microscopy tools were employed to study the transport of fluids and model analytes. These investigations were directed towards evolving improved strategies for rinsing of uncrosslinked monomers to form porous monoliths as well as to effect a desired separation under a set of electrochromatograhic conditions

    Full Text Available The interaction of chemicals with DNA may lead to genotoxicity, mutation or carcinogenicity. A simple open tubular capillary electrochromatographic method is proposed to rapidly assess the interaction affinity of three environmental contaminants (1,4-phenylenediamine, pyridine and 2,4-diaminotoluene to DNA by measuring their retention in the capillaries coated with DNA probes. DNA oligonucleotide probes were immobilized on the inner wall of a fused silica capillary that was first derivatized with 3-(aminopropyl-triethoxysilane (APTES. The difference in retention times and factors was considered as the difference in interaction affinity of the contaminants to the DNA probes. The interaction of the contaminants with both double-stranded (dsDNA and single-stranded DNA (ssDNA coatings was compared. Retention factors of 1,4-phenylenediamine, pyridine and 2,4-diaminotoluene in the capillary coated with ssDNA probe were 0.29, 0.42, and 0.44, respectively. A similar trend was observed in the capillary coated with dsDNA, indicating that 2,4-diaminotoluene has the highest affinity among the three contaminants. The relative standard deviation (RSD for the retention factors was in the range of 0.05-0.69% (n = 3. The results demonstrated that the developed technique could be applied for preliminary screening purpose to provide DNA interaction affinity information of various environmental contaminants.

    A novel monolithic silica column that has a polar-embedded amide-secondary amine group linking with C16 functionality for RP-CEC is described. The amide-secondary aminealkyloxysilane was synthesized by the reaction of 3-(2-aminoethylamino) propyltrimethoxysilane with hexadecanoyl chloride. Then, the silylant agent was bonded to the silica monolith matrix to produce hexadecanamide-secondary amine bonded silica (HDAIS) monolithic column. The electrochromatographic performance of HDAIS monolithic column for the separation of neutral, basic and polar solutes was studied, which was compared to that using the hexadecyl bonded silica monolithic column. The HDAIS monolithic column displayed reduced hydrophobic retention characteristics in the separation of five hydrophobic n-alkylbenzenes and four polar phenols when compared to the hexadecyl bonded silica monolithic column. A very much reduced silanol activity of HDAIS monolithic column was observed in the separation of test basic mixture including four aromatic amines, atenolol and metoprolol with 10 mM borate buffer (pH 7.5) containing 30% v/v ACN as the mobile phase. The comparison results indicate good performance for both polar and basic mixtures on HDAIS monolithic column in RP-CEC, and also show promising results for further applications.

    We describe the microfabrication of an extremely compact optical system as a key element in an integrated capillary channel electrochromatograph with fluorescence detection. The optical system consists of a vertical cavity surface-emitting laser (VCSEL), two high performance microlenses, and a commercial photodetector. The microlenses are multilevel diffractive optics patterned by electron beam lithography and etched by reactive ion etching in fused silica. The design uses substrate-mode propagation within the fused silica substrate. Two generations of optical subsystems are described. The first generation design has a 6 mm optical length and is integrated directly onto the capillary channel-containing substrate. The second generation design separates the optical system onto its own substrate module and the optical path length is further compressed to 3.5 mm. The first generation design has been tested using direct fluorescence detection with a 750 nm VCSEL pumping a 10 -4 M solution of CY-7 dye. The observed signal-to-noise ratio of better than 100:1 demonstrates that the background signal from scattered pump light is low despite the compact size of the optical system and is adequate for system sensitivity requirements.

    This volume of the proceedings ''Symmetries in Science XVI'' is dedicated to the memory of Miguel Lorente and Allan Solomon who both participated several times in these Symposia. We lost not only two great scientists and colleagues, but also two wonderful persons of high esteem whom we will always remember. Dieter Schuch, Michael Ramek There is a German saying ''all good things come in threes'' and ''Symmetries in Science XVI'', convened July 20-26, 2013 at the Mehrerau Monastery, was our third in the sequel of these symposia since taking it over from founder Bruno Gruber who instigated it in 1988 (then in Lochau). Not only the time seemed to have been perfect (one week of beautiful sunshine), but also the medley of participants could hardly have been better. This time, 34 scientists from 16 countries (more than half outside the European Union) came together to report and discuss their latest results in various fields of science, all related to symmetries. The now customary grouping of renowned experts and talented newcomers was very rewarding and stimulating for all. The informal, yet intense, discussions at ''Gasthof Lamm'' occurred (progressively later) each evening till well after midnight and finally till almost daybreak! However, prior to the opening ceremony and during the conference, respectively, we were informed that Miguel Lorente and Allan Solomon had recently passed away. Both attended the SIS Symposia several times and had many friends among present and former participants. Professor Peter Kramer, himself a long-standing participant and whose 80th birthday commemoration prevented him from attending SIS XVI, kindly agreed to write the obituary for Miguel Lorente. Professors Richard Kerner and Carol Penson (both also former attendees) penned, at very short notice, the tribute to Allan Solomon. The obituaries are included in these Proceedings and further tributes have been posted to our conference website. In 28 lectures and an evening poster

    A simple but effective frit formation technique was developed to stabilize the packing structure inside the microchannel of capillary electrochromatographic microchips, utilizing the electroless plating technique. A Ag(NH(3))(2)(+) solution was allowed to diffuse through the colloidal silica packing in the microchannel from the reservoir of the microchip for a limited amount of time, and then it was reduced by an excess amount of formaldehyde solution. A frit structure of ~70 μm in length was formed at the entrance of the microchannel without clogging when treated with 1mM Ag(NH(3))(2)(+) ion and formaldehyde for 30s and 150 s, respectively. The formation of the frit structure was confirmed by a scanning electron microscopy. The stability of the packing structure was tested rigorously and then confirmed by applying alternating electroosmotic flows back and forth with pulsed potential steps on both sides of the frit structure. The effect of the treatment on the electrochromatograms was evaluated after the microchips were repeatedly used and stored for a long period of time. The results indicated that the silver-cemented frit structure extended the lifetime of the fully packed CEC microchips distinctly. Copyright © 2011 Elsevier B.V. All rights reserved.

  7. Onium ions. XVI. Hydrogen--deuterium exchange accompanying the cleavage of ammonium (tetradeuterioammonium) trifluoroacetate by lithium deuteride (hydride) indicating Sn2 like nucleophilic displacement at quaternary nitrogen through pentacoordinated NH5

    The reactions of ammonium trifluoroacetate and lithium hydride, of ammonium trifluoroacetate and lithium deuteride, and of tetradeuteroammonium trifluoroacetate and lithium hydride were studied in an attempt to prove experimentally nucleophilic displacement through the formation of pentacoordinated NH 5 . Significant isotopic scramblings were observed in the reaction products. An analysis of possible side reactions indicated that the most reasonable explanation for the reaction products obtained is the attack of D - on the quarternary hydrogen of NH 4 + in an SN2-like fashion causing exchange to occur via pentacoordinated NH 4 D. The possibility of a real pentacoordinated intermediate was also considered. CNDO/2 calculations show that a nucleophilic attack on hydrogen is favored, but the alternative attack on nitrogen can not be dismissed because of the experimental data. The reaction of NF 4 + SbF 6 - and LiF could indicate the possibility of nucleophilic attack on nitrogen. (U.S.)

    Full Text Available El concepto de usura, coincidente en la práctica con el significado actual de interés del dinero, apenas ha variado con el transcurso del tiempo hasta el siglo XVIII, en que al ser sustituido por la nueva denominación de interés, pasó a ser considerado sólo como el interés excesivo o abusivo; pero desde el principio su aplicación a las operaciones comerciales y financieras en el mundo occidental fue en general rechazada por parte de las autoridades eclesiásticas, cierto que con alguna vacilación derivada de una progresiva admisión del lucro cesante, en tanto que las autoridades civiles solieron ser más permisivas, aunque impusieran límites a los tipos de usura=interés.Con objeto de llegar a conocer la idea que se tenía acerca de la usura en la España del siglo XVI, se pasa revista sucesivamente: al criterio de los autores coetáneos de obras de aritmética que se ocuparon del cálculo comercial; a la resolución de las consultas formuladas por los mercaderes a renombrados teólogos de la época en relación con operaciones mercantiles de dudosa licitud, y a la doctrina que los doctores moralistas han ido elaborando en sus tratados a lo largo del siglo en materia de usura, justo precio, daño emergente, lucro cesante y otros conceptos económicos, sobre la base del rechazo en principio de la usura en toda operación que, más o menos solapadamente, pudiera suponer la existencia de un préstamo retribuido.Se analizan a continuación tres de las operaciones comerciales y financieras típicas de la época en que ‒no siempre claramente‒ interviene la usura=interés: los cambios, los juros y los asientos. En cuanto a los cambios, se estudian sus distintas clases, con especial atención al cambio por letras y dentro de éste al cambio exterior, que en principio era aceptado como lícito siempre que se mantuviera dentro de plazos cortos ‒sin saltarse ferias‒ y se respetasen la distancia loci y el justo precio.

Representan la Lapidación de San Esteban, San Julián y Santa Basilisa haciendo la limosna y santo obispo bendiciendo los campos. Sus dimensiones aproximadamente iguales hacen pensar que las tres tablas formaron parte de un retablo. Tanto por su iconografía como por su colorido manierista pueden considerarse como pinturas propias de la Contrarreforma de hacia 1590, lo que se hace evidente en la Lapidación de San Esteban que copia una estampa grabada de Ecclesiae Militantes Triunphi (Roma, 1585 que recoge la iconografía jesuítica de la Contrarreforma dedicada a los primeros mártires del cristianismo a los que se relaciona con la doctrina teológica del Concilio de Trento.

    In this special issue of CAMOP/Physica Scripta we would like to present a picture of the state-of-the-art in the field of the dynamics of molecular systems. It contains a collection of papers submitted in association with the most recent MOLEC meeting (MOLEC XVI), which was held in September 2006 in Levico Terme (Italy) to celebrate the 30th anniversary of the MOLEC conference series. The series of biennial European Conferences on the Dynamics of Molecular Systems (MOLEC) started in 1976, when the first meeting was held in Trento (Italy). Successive conferences were organized in Brandbjerg Højskole (Denmark, 1978), Oxford (UK, 1980), Nijmegen (The Netherlands, 1982), Jerusalem (Israel, 1984), Aussois (France, 1986), Assisi (Italy, 1988), Bernkastel-Kues (Germany, 1990), Prague (Czech Republic, 1992), Salamanca (Spain, 1994), Nyborg Strand (Denmark, 1996), Bristol (UK, 1998), Jerusalem (Israel, 2000), Istanbul (Turkey, 2002) and Nunspeet (The Netherlands, 2004). This is the second time that Physica Scripta has hosted a special issue dedicated to MOLEC. The previous issue ( Physica Scripta (2006) 73 C1-C89) was edited by Steven Stolte and Harold Linnartz following the MOLEC 2004 conference. Following the philosophy of CAMOP, we have asked invited speakers to summarize important problems in their research area, with the objective of setting forth the current thinking of leading researchers in atomic, molecular and optical physics. This comprises discussions of open questions, important new applications, new theoretical and experimental approaches and also predictions of where the field is heading. In addition to being authoritative contributions of acknowledged experts, we hope that the papers also appeal to non-specialists as each work contains a clear and broad introduction and references to the accessible literature. The present special issue comprises 17 papers, which are arranged according to the following topics: theoretical and experimental studies of

    Full Text Available This paper analyzes the importance of cocoa in the Alcaldía Mayor of Sonsonate, particularly in the Izalco region, during the last pre-Columbian period and also its exploitation during the XVIth century. It is demonstrated that, during the first half of these century, despite of the development of the encomienda system, the natives significantly controlled the production and exchange of cocoa, and also the property of the land. Nevertheless, during the second half of this century, the increase of cocoa production induced serious perturbations in the Indian communities because of the demographic collapse, the usurpation of the lands and the ladinoization processes.

    Este estudio analiza la importancia del cacao en la Alcaldía Mayor de Sonsonate, especialmente en la región de los Izalcos, durante el último periodo prehispánico así como su explotación en el XVI. Se demuestra que, durante la primera mitad de este siglo, a pesar del desarrollo de la encomienda, la población indígena controló, en buena medida, la producción y el intercambio del cacao, así como la propiedad de la tierra. También se pone de manifiesto que, a partir de la segunda mitad de este mismo siglo, el incremento de la producción cacaotera provocó daños irreversibles en las comunidades indígenas debido al más que notable descenso demográfico, a la usurpación de sus tierras y a los procesos de ladinización.

    Full Text Available The resurrection of Jesus according to Jozef Ratzinger/Benedictus XVI. As a follow-up to my earlier article in HTS Teologiese Studies/Theological Studies (‘The Pope’s Jesus book and the Christologies of the gospels’ [2011], this contribution concerning the Jesus trilogy by Jozef Ratzinger will discuss the idea he presents of Jesus’ resurrection and how his view should be assessed from the perspective of the current state of affairs in biblical scholarship. In addition, this article articulates a number of proposals that can take the discussion a step further. In that context, the following questions are dealt with: What is meant when we speak about the body of the risen Jesus? Are there – except for terms like ‘to raise from the dead’ or ‘to rise up’ – other formulas used in the New Testament to describe the fundamental reversal after Jesus’ death? Can Ratzinger’s biased focus upon the concept of ‘resurrection’ be expanded on the basis of other Old Testament models of thought or faith paradigms that can help us to understand that Jesus, through the agency of God, has come to share in a life that is no longer limited by death? What factors played a role in the origin of the belief in Jesus’ resurrection? This article shows that Ratzinger too strongly emphasises continuity between the historical Jesus and a number of New Testament Christologies and the way in which they were crystallised in later ecclesiastical dogmatic formulations.

    Geostationary satellites are unique among orbital spacecraft in that they experience no appreciable atmospheric drag. After concluding their respective missions, geostationary spacecraft remain in orbit virtually in perpetuity. As such, they represent some of human civilization's longest lasting artifacts. With this in mind, the EchoStar XVI satellite, to be launched in fall 2012, will play host to a time capsule intended as a message for the deep future. Inspired in part by the Pioneer Plaque and Voyager Golden Records, the EchoStar XVI Artifact is a pair of gold-plated aluminum jackets housing a small silicon disk containing 100 photographs. The Cover Etching, the subject of this paper, is etched onto one of the two jackets. It is a temporal map consisting of a star chart, pulsar timings, and other information describing the epoch from which EchoStar XVI came. The pulsar sample consists of 13 rapidly rotating objects, 5 of which are especially stable, having spin periods <10 ms and extremely small spin-down rates. In this paper, we discuss our approach to the time map etched onto the cover and the scientific data shown on it, and we speculate on the uses that future scientists may have for its data. The other portions of the EchoStar XVI Artifact will be discussed elsewhere.

    2002-02-01

    The great majority of historians agree that the marriage of Louis XVI and Marie-Antoinette was only consumated seven years after the official ceremony. This delay could have been due to a genital malformation (phimosis) of Louis XVI, a strict religious education, a traumatic childhood and the young age of the two spouses, factors that may have inhibited their sexuality. In this article, the authors try to determine whether Louis XVI was able to overcome his sexual difficulties following an operation (circumcision) or as a result of spontaneous cure.

    Based on data aquired in 13 orbits of Hubble Space Telescope time, we present a detailed evolutionary history of the M31 dSph satellite Andromeda XVI, including its lifetime star formation history (SFH), the spatial distribution of its stellar populations, and the properties of its variable stars. And XVI is characterized by prolonged star formation activity from the oldest epochs until star formation was quenched ∼6 Gyr ago, and, notably, only half of the mass in stars of And XVI was in place 10 Gyr ago. And XVI appears to be a low-mass galaxy for which the early quenching by either reionization or starburst feedback seems highly unlikely, and thus it is most likely due to an environmental effect (e.g., an interaction), possibly connected to a late infall in the densest regions of the Local Group. Studying the SFH as a function of galactocentric radius, we detect a mild gradient in the SFH: the star formation activity between 6 and 8 Gyr ago is significantly stronger in the central regions than in the external regions, although the quenching age appears to be the same, within 1 Gyr. We also report the discovery of nine RR Lyrae (RRL) stars, eight of which belong to And XVI. The RRL stars allow a new estimate of the distance, (m − M){sub 0} = 23.72 ± 0.09 mag, which is marginally larger than previous estimates based on the tip of the red giant branch.

    Full Text Available The Bible in the culture of Polish-Lithuanian Rus’ in the sixteenth century Beginning in the mid-fourteenth century, the East Slavic citizens of the Polish-Lithuanian Commonwealth (“Ruthenians,” the “Rutheni” took active part in a process of multicultural inte­gration. The increase of interests in the biblical text that took place in Europe in that period was not without influence on Ruthenians – both those who remained Orthodox and those who became followers of the Reformation. The article discusses two outstanding figures: Matvej Ioannovič Desjatyj (the biblical codex of Vilnius and Supraśl, 1502–1507 and Francisk Skorina (Prague edi­tion of 23 Books of the Slavonic Bible – Bivlija ruska of 1517–1520, the Vilnius edition of Malaja podorožnaja knižka – The little traveller’s book, 1522, and the Apostolos of 1525. The article also examines how the circle of the Ostroh Academy approached the task of preparing a print edition of the Slavonic Bible (1580–1581 and investigates the viewpoint of those who were influenced by Reformation ideas as well as that of those promoting the usage of prosta/rus’ka mova. This biblical production, which is only a part of the literary activity undertaken in Rus’, testifies to the high level of Ruthenian culture in the Polish-Lithuanian state and shows how Ruthenians were able to match their traditional spirituality with the philologia sacra of the Renaissance.   Biblia w kulturze Rusi polsko-litewskiej w XVI wieku Od połowy XIV wieku wschodniosłowiańscy obywatele Rusi polsko-litewskiej brali czynny udział w procesie wielokulturowej integracji.

    N-type calcium channels play important roles in the control of neurotransmission release and transmission of pain signals to the central nervous system. Their selective inhibitors are believed to be potential drugs for treating chronic pain. In this study, a novel neurotoxin named Huwentoxin-XVI (HWTX-XVI) specific for N-type calcium channels was purified and characterized from the venom of Chinese tarantula Ornithoctonus huwena. HWTX-XVI is composed of 39 amino acid residues including six cysteines that constitute three disulfide bridges. HWTX-XVI could almost completely block the twitch response of rat vas deferens to low-frequency electrical stimulation. Electrophysiological assay indicated that HWTX-XVI specifically inhibited N-type calcium channels in rat dorsal root ganglion cells (IC50 ∼60 nM). The inhibitory effect of HWTX-XVI on N-type calcium channel currents was dose-dependent and similar to that of CTx-GVIA and CTx-MVIIA. However, the three peptides exhibited markedly different degrees of reversibility after block. The toxin had no effect on voltage-gated T-type calcium channels, potassium channels or sodium channels. Intraperitoneal injection of the toxin HWTX-XVI to rats elicited significant analgesic responses to formalin-induced inflammation pain. Toxin treatment also changed withdrawal latency in hot plate tests. Intriguingly, we found that intramuscular injection of the toxin reduced mechanical allodynia induced by incisional injury in Von Frey test. Thus, our findings suggest that the analgesic potency of HWTX-XVI and its greater reversibility could contribute to the design of a novel potential analgesic agent with high potency and low side effects.

    2006-06-01

    Full Text Available In this study, we will learn about the spiritual life and religious attitudes of the Sephardim of Ragusa, during the sixteenth and seventeenth centuries, by examining
    Jewish wills preserved in the Historical Archives of Dubrovnik. These wills were drafted by Christian notaries and later deposited in the local registry. While some of the wills are lengthy and others succinct, they all attest to the importance of these bequests in their dual role as spiritual and economic documents. The bequests and legacies, with their emphasis on donations to charitable causes and on bringing order to one’s worldly possessions, reveal much about the donor’s social-spiritual world, about his economic status and his spiritual priorities. We learn, for example, about the importance of preserving unison within the family and about the special connection to the Land of Israel. Reflected as well in these documents is the influence of the Catholic cultural milieu.

    A partir de testamentos que se conservan en el Archivo Histórico de Dubrovnik, este estudio intenta dar a conocer aspectos de la vida espiritual y de la actitud religiosa de los sefardíes de Ragusa en los siglos XVI y XVI. Se trata de testamentos judíos, otorgados ante notarios cristianos que luego los consignan en el registro local. Aunque su extensión es desigual, confirman todos ellos la importancia del legado testamentario en su doble vertiente espiritual y económica. Las mandas y legados de carácter moral, asistencial y crematístico dejan entrever el mundo socio-espiritual de los causantes, su nivel económicco y sus prioridades espirituales así como la cohesión familiar y la relación con la Tierra de Israel, reflejando también la influencia del medio cultural católico circundante.

    Full Text Available Partindo de algumas das polêmicas opiniões de Bento XVI, o artigo busca compreender a base doutrinária delas e discutir os seus efeitos para a questão da tolerância religiosa. Depois de uma apresentação do que entende por tolerância, propõe um percurso através da encíclica Deus caritas est, que embasa a nova doutrina papal numa interpretação particular da noção de "amor de Deus". Por fim, tenta-se mostrar como esse "amor", mediante uma ênfase exagerada da idéia de identidade, torna-se nos documentos papais um instrumento de combate a todas as diferenças, pondo a perder a possibilidade de convivência entre as religiões e, por conseqüência, semeando o fundamentalismo.This article tries to comprehend the doctrinal base of some polemical assessments of Benedict XVI; discussing its effects on the issue of religious tolerance. After presenting what is understood to mean tolerance, it proposes a way through the encyclical letter Deus caritas est; in this letter, the new papal doctrine is founded on a particular interpretation of the notion of "God's love". Lastly, it intends to show how this "love", by an exaggerated emphasis on the idea of identity, becomes an instrument of fight against every difference, spoiling the possibility of a pacific relationship among the religions and, consequently, sowing the seeds of fundamentalism.

  13. A comprehensive set of UV and x-ray radiative transition rates for Fe XVI

    International Nuclear Information System (INIS)

    2009-01-01

    Sodium-like Fe XVI is observed in collisionally ionized plasmas such as stellar coronae and coronal line regions of active galactic nuclei including black hole-accretion disc environments. Given its recombination edge from neon-like Fe XVII at ∼/!25 A, the Fe XVI bound-bound transitions lie in the soft x-ray and EUV (extreme ultraviolet) range. We present a comprehensive set of theoretical transition rates for radiative dipole allowed E1 transitions including fine structure for levels with nl(SLJ)≤10, l≤9 using the relativistic Breit-Pauli R-matrix (BPRM) method. In addition, forbidden transitions of electric quadrupole (E2), electric octupole (E3), magnetic dipole (M1) and magnetic quadrupole (M2) type are presented for levels up to 5g(SLJ) from relativistic atomic structure calculations in the Breit-Pauli approximation using code SUPERSTRUCTURE. Some of the computed levels are autoionizing, and oscillator strengths among those are also provided. BPRM results have been benchmarked with the relativistic coupled cluster method and the atomic structure Dirac-Fock code GRASP. Levels computed with the electron collision BPRM codes in bound state mode were identified with a procedure based on the analysis of quantum defects and asymptotic wavefunctions. The total number of Fe XVI levels considered is 96, with 822 E1 transitions. Tabulated values are presented for the oscillator strengths f, line strengths S and Einstein radiative decay rates A. This extensive dataset should enable spectral modelings up to highly excited levels, including recombination-cascade matrices.

    Full Text Available O objetivo primacial desta pesquisa é investigar como solucionam os habitantes de Cochim, na Índia, seus problemas de saúde, quando não podem aceder aos sistemas convencionais ou quando optam por aceder a sistemas alternativos, na modernidade. O objetivo específico da pesquisa é compilar as espécies vegetais de uso terapêutico no século XVI e compará-las com as atuais. A flora indiana, em particular as especiarias, tem fascinado a humanidade desde o início dos tempos. Em 1498, os portugueses descobriram o caminho marítimo para a Índia e, durante os dois séculos seguintes, o pequeno país europeu dominou o comércio mundial com o oriente. Seguindo a rota das especiarias, o Instituto de Investigação Científica Tropical (IICT organizou, recentemente, uma missão científica a Kerala, a fim de investigar os frutos, os legumes, os condimentos, os tubérculos e as plantas medicinais cultivadas em jardins e pátios traseiros, vendidos em mercados e feiras, e recomendados pela medicina Ayurvédica, na cidade de Cochim. O ponto de partida foi a leitura de quatro manuscritos do século XVI que enumeravam as plantas aromáticas, condimentares e medicinais da Índia renascentista. Os resultados demonstram que um número substancial de plantas colhidas durante a missão do IICT, em 2013, já era usado na Índia, no século XVI.

    We present the first comparison between the lifetime star formation histories (SFHs) of M31 and Milky Way (MW) satellites. Using the Advanced Camera for Surveys on board the Hubble Space Telescope, we obtained deep optical imaging of Andromeda II (And II; M{sub V} = –12.0; log(M {sub *}/M {sub ☉}) ∼ 6.7) and Andromeda XVI (And XVI; M{sub V} = –7.5; log(M {sub *}/M {sub ☉}) ∼ 4.9) yielding color-magnitude diagrams that extend at least 1 mag below the oldest main-sequence turnoff, and are similar in quality to those available for the MW companions. And II and And XVI show strikingly similar SFHs: both formed 50%-70% of their total stellar mass between 12.5 and 5 Gyr ago (z ∼ 5-0.5) and both were abruptly quenched ∼5 Gyr ago (z ∼ 0.5). The predominance of intermediate age populations in And XVI makes it qualitatively different from faint companions of the MW and clearly not a pre-reionization fossil. Neither And II nor And XVI appears to have a clear analog among MW companions, and the degree of similarity in the SFHs of And II and And XVI is not seen among comparably faint-luminous pairs of MW satellites. These findings provide hints that satellite galaxy evolution may vary substantially among hosts of similar stellar mass. Although comparably deep observations of more M31 satellites are needed to further explore this hypothesis, our results underline the need for caution when interpreting satellite galaxies of an individual system in a broader cosmological context.

  10. Novel tentacle-type polymer stationary phase grafted with anion exchange polymer chains for open tubular CEC of nucleosides and proteins.

    Science.gov (United States)

    Aydoğan, Cemil; Çetin, Kemal; Denizli, Adil

    2014-08-07

    A novel and simple method for preparation of a tentacle-type polymer stationary phase grafted with polyethyleneimine (PEI) anion exchanger was developed for open tubular capillary electrochromatography (OT-CEC) of nucleosides and proteins. The polymeric stationary phase was prepared using 3-chloro-2-hydroxypropyl methacrylate (HPMA-Cl)-based reactive monomer. The preparation procedure included pretreatment of the capillary inner wall, silanization, in situ graft polymerization with HPMA-Cl and PEI modification. To compare with the tentacle-type capillary column with PEI functionalization, a monolayer capillary column without PEI functionalization was also prepared. The electrochromatographic characterization of the prepared open tubular column was performed using alkylbenzenes. The electroosmotic flow (EOF) with regard to PEI concentrations and the running buffer pH was investigated. The separation conditions of the nucleosides and the proteins were optimized. The modified tentacle-type column with high anion exchange capacity has proven to afford better retention and resolution for the separation of nucleosides and proteins. The PEI functionalization column can also provide long-term stable use for biomolecule separation using a single capillary with relative standard deviation values of retention times of less than 2%. The results indicate that the present method for open tubular capillary preparation with a HPMA-Cl-based reactive monomer is promising for OT-CEC biomolecule separation.

    Full Text Available This article discusses the emergence of empirical practices in the context of the sixteenth-century Spanish American empire. My thesis is simple: the commercial and imperial expansion of Spain in America (as well as the expansion of other European kingdoms afterwards fostered the creation and institutionalization of empirical practices for the study of the natural world. This was a significant event that has not yet been well understood in history of science. In the traditional historiography of the history of science the emphasis has been placed on the European social mechanisms that helped to establish empirical practices. It does not consider the American experience central in the understanding of the emergence and institutionalization of those practices; I argue that the American experience was central in the development of modern science. This article studies the creation of questionnaires and expeditions not only as part of state formation but also as part of the development of modern science.// En este artículo se discute la aparición de prácticas empíricas durante el siglo XVI en el contexto del imperio hispanoamericano. La tesis es simple: la expansión comercial e imperial de España en América (al igual que la de otros reinos Europeos más tarde impulsó la creación e institucionalización de prácticas empíricas para el estudio de la naturaleza americana. Este fue un evento significativo en el desarrollo de la ciencia moderna que no ha recibido la atención adecuada de los historiadores de la ciencia. La historiografía tradicional ha discutido los mecanismos sociales que ayudaron a establecer prácticas empíricas como parte de la ciencia moderna, pero no considera la experiencia de América como un elemento central en el desarrollo de esas prácticas durante el siglo XVI Existe una correlación clara pero todavía no estudiada entre el proceso de conquista y colonización de América y el desarrollo de prácticas emp

    Full Text Available Este artículo presenta un tipo de violencia familiar protagonizado por madres e hijas navarras de los siglos XVI y XVII. Las acu-saciones por lenocinio o alcahuetería contra las madres que emplearon a sus propias hijas en sus tratos de mediadoras sirven para ilustrar una forma de violencia que supone, entre otras cosas, una ruptura del amor materno. La preca-ria situación de la madre y las dificultades tras el fallecimiento del esposo —la gran parte de los casos están protagonizados por madres viu-das— fue el contexto general en el que se desarrollaron los malos tratos. La historia de estas mujeres representa un mal ejercicio de la autoridad materna y una forma de violencia hacia las hijas; una violencia no siempre física, pero sí emocional y psicológica.

    Full Text Available At the end of the XV century and at the beginning of the XVI century one of the most powerful strongholds in Europe, the Kremlin, was built in Moscow. This building was made thanks to the engineering, architectonic and mechanical genius of the Italian masters who had come to Russia by request of the Great Prince Ivan the Third. The Italian architects were able to combine the Russian architectural style with the style of the Italian Renaissance, applying the new technologies and using state-of-the-art tools. This article deals with the all the works carried out by the Italian masters in the area of Moscow and with the building techniques that they introduced in the Russian capital.

    Full Text Available Human osseal remains from the cemetery of Zatveretsky Posad at the historical Russian city of Tver revealed the data on its population in XVI-XVIII centuries. Obtained data generally agreed with the material from other contemporaneous necropoles of the city. Domination of male burials and underrepresentation of younger individuals are accompanied by the signs of poor oral hygiene. Caries has not only often destroyed majority of molars in males and females by the age of 45-50 years, but affected teeth of teenagers and even younger individuals. The heavily developed dental calculus is one of the signs of insufficient oral hygiene in adults. Possible kinship between buried is manifested by similar genetically determined cranial anomalies.

Es un intento de encontrar unidad a algunas investigaciones dispersas que se van publicando sobre el tema. Los cartularios que existen de algunas universidades extranjeras son insuficientes y los libros de registros de estudiantes o de grados no nos han llegado apenas desde las alturas de aquellos siglos xn-xvi. Sin embargo una intensa indagación en los archivos municipales y catedralicios podría arrojar, para este caso, los datos suficientes.

    Weller, M. E.; Beiersdorfer, P.; Soukhanovskii, V. A.; Scotti, F.; LeBlanc, B. P.

    2018-02-01

    We present electron-density-sensitive line ratios for Fe XIII– XVI measured in the spectral wavelength range of 200–440 Å and an electron density range of (1–4) × 1013 cm‑3. The results provide a test at the high-density limit of density-sensitive line ratios useful for astrophysical studies. The measurements were performed on the National Spherical Torus Experiment-Upgrade, where electron densities were measured independently by the laser Thomson scattering diagnostic. Spectra were collected with a flat-field grazing-incidence spectrometer, which provided a spectral resolution of up to 0.3 Å, i.e., high resolution across the broad wavelength range. The response of the instrument was relatively calibrated using spectroscopic techniques in order to improve accuracy. The line ratios are compared to other laboratory sources and the latest version of CHIANTI (8.0.2), and an agreement within 30% is found.

    Full Text Available De sobra es conocido que los Libros de Oro, que aparecen en el siglo XVI en el marco de la renovación pedagógica que introdujo el Humanismo y el Renacimiento, son colecciones de pensamientos, sentencias, máximas y proverbios morales entresacados de las obras de los mejores filósofos estoicos de la Antigüedad Clásica. Sin embargo, poco más es lo que se conoce de ellos fuera del marco de la Historia de la Literatura. Incidentalmente, al ocuparse de la preceptiva de príncipes, algo se ha dicho sobre los textos áureos de la vida, si bien de forma tangencial. Consciente de esta laguna historiográfica voy a redactar las siguientes notas críticas, que no tienen otro objeto más que colaborar en el debate que historiadores, filósofos, pedagogos y literatos han de sostener sobre el tema. Nuestro país aportó al pensamiento educativo del siglo xvi dos figuras señeras: Luis Vives y Pedro Simón Abril. Pero su obra quedó en el plano teórico por cuanto carecieron de capacidad u oportunidad política para implantar sus doctrinas en la sociedad española. Alguna posibilidad tuvo el segundo de los autores citados, pero las mismas se quedaron en forma de memoriales o apuntamientos dirigidos al Rey Felipe II.

    Full Text Available Bien que la Révolution française ait suscité l’intérêt des chercheurs du monde entier, Louis xvi fait figure de parent pauvre des études universitaires. Même si c’est à son corps défendant, il en est tout de même l’un des principaux protagonistes et la Révolution s’est aussi construite en interrogeant le rôle et la place du roi. Cette situation a eu pour conséquence de conserver vivace la légende dorée que le roi s’est construite en exerçant un contrôle sur son image dès le début de son règne. Elle l’assimile à un nouvel Henri iv, profondément concerné par les maux de ses sujets. Malgré les attaques de la Révolution, cette image continue à exercer une influence considérable sur les biographes de Louis xvi et les historiens de la Révolution.Si la Restauration en a fait un usage sans surprise, elle a, de manière plus étonnante, séduit jusqu’à Jaurès avant de souffrir du discrédit dans lequel sombre le royalisme en choisissant l’antisémitisme au xxe siècle. Néanmoins, c’est aujourd’hui par le détour de l’historiographie anglo-saxonne qu’elle fait sa réapparition et commence seulement à être questionnée.Although the French Revolution has aroused interest of international researchers, Louis xvi is widely neglected by the academic studies. Even if reluctantly, he is yet one of the main protagonists and it is also by questioning the role and the place of the king that the Revolution took its shape.This led to the consequence that the golden legend the king constructed by controlling his image from the beginning of his reign is still very lively today. In it, he is presented as a new Henri iv, deeply concerned by the misfortunes of his subjects. In spite of the attacks of the Revolution, this image still considerably influences Louis xvi’s biographers and the historians of the Revolution.If the Restoration made a not surprising good use of it, it more astonishingly seduced Jaur

    Full Text Available Durante la Edad Moderna, las Inquisiciones de España y de Portugal se vieron obligadas a mantener una comunicación constante, que permitió el intercambio regular de información relativa a posibles herejes, sobre todo judaizantes. Muchos más problemas generó el espinoso asunto de la remisión de reos de un reino a otro. A pesar de los intentos de la Inquisición española, en el siglo XVI, y de la portuguesa, en el XVII, para que se estableciesen los casos y supuestos en los que podrían extraditarse herejes, nunca se llegó a firmar ningún acuerdo entre los dos tribunales. Por ello, las remisiones de reos de un reino a otro se debieron siempre a la voluntad de los sucesivos inquisidores generales, a las estrategias concretas de cada tribunal de distrito y a factores coyunturales.During the Early Modern Age, the Portuguese and Spanish Inquisition kept continuous communication, which allowed them the regular exchange of information regarding heretics, especially that of Judaism. More problems were generated by the hard issue of the extradition of accused between the two kingdoms. Despite the efforts on both sides, no agreement was signed regarding what fact and circumstances would dictate the extradition of Heretics, between Portugal and Spain. For this reason, the extraditions from a kingdom to the other were always due to the wishes of the different general inquisitors, to the specific strategies of each district tribunal and to current circumstances.

    To analyse the dental remains of an individual with signs of congenital syphilis by using macroscopic observation, CBCT and micro-CT images, and the analysis of the enamel thickness. Anthropological analysis of human skeletal remains from the 16th century archaeological site Park Grič in Zagreb, Croatia discovered a female, 17-20 years old at the time of death, with dental signs supportive of congenital syphilis: mulberry molars and canine defects, as well as non-specific hypoplastic changes on incisors. The focus of the analysis was on three aspects: gross morphology, hypoplastic defects of the molars, canines and incisors, as well as enamel thickness of the upper first and second molars. The observed morphology of the first molars corresponds to the typical aspect of mulberry molars, while that of the canines is characterised by hypomineralisation. Hypoplastic grooves were observed on the incisal edges of all incisors. The enamel of the first molars is underdeveloped while in the second molars a thick-enamelled condition is observed. Our observations for the dental and skeletal evidence are supportive to a diagnosis of congenital syphilis for this specimen from XVI century Croatia. The use of CT imaging helped documenting the diagnostic features and quantifying the effect of the dental stigmata on first molars. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The goal of Image Guided Radiotherapy (IGRT) is to improve the accuracy of treatment delivery. In this technique, it is possible to get volumetric images of patient anatomy before delivery of treatment.XVI( release 3.5) system in Elekta Synergy linear accelerator (Elekta,Crawley,UK) has the potential to ensure that, the relative positions of the target volume is same as in the treatment plan. It involves acquiring planar images produced by a kilo Voltage cone beam rotating about the patient in the treatment position. After 3 dimensional match between reference and localization images, the system gives rotational errors also along with translational shifts. One can easily perform translational shifts with treatment couch. But rotational shifts cannot be performed. Most of the studies dealt with translational shifts only. Few studies reported regarding rotational errors. It is found that in the treatment of elongated targets, even small rotational errors can show difference in results. The main objectives of this study is 1) To verify the magnitude of rotational errors in different clinical sites observed and to compare with the other reports. 2) To find its clinical relevance 3) To find difference in rotational shift results with improper selection of kV collimator

    Full Text Available In his two homilies dedicated to the Arian controversy (the only surviving of the original five Photios uses different methods to actualize the matter for the broad Byzantine public, mainly in connection with the patriarch’s main concern during his fi rst tenure: the polemics against Iconoclasm. The Arianism was chosen as a purely logical juxtaposition to the latter, where the real gradual progress of iconoclast tendencies is compared to a theoretical construction of Arianism which has little to do with the actual developments in the IVth century. The comparison of the Iconoclast heresiarch John the Grammarian to Arius is chiefly aimed at justifying the permanent deposition of Iconoclast priests even in case of repentance, declared by the Patriarch Nikephoros in 815 and carried out by Methodios in 843. The triadological considerations in the Homily XVI do not in fact pertain to anti- fi lioque polemics, but rather represent a traditional Eastern conception. This, as well as the intense and negative attention to the Council of Sardica suggest the date 861, when Photios had to argue against the applicability of this council’s 10th canon to his promotion to patriarch from a layman.

    Full Text Available Comparar los moriscos con los indígenas americanos es un tema que se repite en la obra de Francisco de Vitoria. Este ensayo se centra en dos procesos inquisitoriales (ambos de mediados del s. XVI para explorar uno de los intereses transatlánticos de Vitoria: la relación entre conversión e iconoclasia. El primer proceso se desarrolla en el pueblo de Yanhuitlán, en Nueva España; el segundo, en la ciudad de Valencia, en los reinos de Aragón. Ambos procesos hablan de "ruinas nuevas"-es decir, ruinas recientes producidas a causa de la violencia iconoclasta cristiana. En el caso de Yanhuitlán, de las ruinas de un recinto sagrado indígena. En el caso de Valencia, de las ruinas de una mezquita. Este ensayo explora el significado de estas ruinas, y del concepto de ruina en general, desde los puntos de vista ofrecidos por las tradiciones católica, musulmana, e indígena. Estas tradiciones tenían visiones distintas de lo que era una ruina y, por ello, la iconoclasia cristiana tuvo consecuencias inesperadas, tanto en Valencia como en Nueva España.

Escasean los documentos, y cuando los hay se fijan en las talas y abusos cometidos por los vecinos o en las preocupaciones -normativas concejiles- de buena utilización de la leña y la madera. La Orihuela foral, siglos XVI y XVII, gozaba de una amplia extensión de terrenos comunales donde el pastoreo convivía con el aprovechamiento silvícola. El presente estudio marca los límites del monte, concretamente del arbolado, al tiempo que cuantifica, como propuesta, los distintos espacios que configuraban el paisaje del Bajo Segura: huerta, boalares, redondas y realengo. Normas y leyes que reglamentaban cortes y talas, así como los malos usos del bosque -carboneo e incendios-, son también analizados para entender el proceso de deforestación y su control a lo largo de las citadas centurias.

El morabetí era un impuesto, instituido en 1266, y remodelado en 1301, que se recogía periódicamente, cada siete años, de los cabezas de familia de la isla, con bienes superiores a las diez libras. Su recaudación nos da a conocer el número de hogares o fuegos, que tributaban el impuesto, y si a éstos, se les aplicara un coeficiente que fuera adecuado, tendríamos la cifra de la población existente en cada año de recaudación en Mallorca.

En el caso específico de Tzintzuntzan se ha dudado si en realidad este proceso se llevó a cabo, pues no se ha encontrado el acta de su congregación. Después de analizar distintos manuscritos coloniales, crónicas, estudios previos, tradición oral, así como la traza urbana de la ciudad, se deduce que Tzintzuntzan tuvo al menos dos momentos de reorganización urbano-social. El primero que se llevó a cabo en la década de 1530 con la reubicación del convento y una parte de la población que estaba asentada en las laderas del cerro Tariácuri. El segundo debió llevarse a cabo a finales del siglo xvi o principios del xvii, con el traslado de varios de sus barrios sujetos hacia la cabecera.

    Full Text Available The history of the diocese of Turov and Pinsk until the end of the XVI century reflects the fate of the Orthodox Church in the Commonwealth. The development of the bishopric founded in 1088 passed through several stages resulting from often violent political, administrative and state changes. The prosperous period in the evolution of the Church structures on the territory of the discussed eparchy lasted until the end of the XII century. Under the rule of SviatopolkII (1087–1113 the diocese of Turov encompassed vast territories of the Ruthenian lands with the following towns: Turov, Pinsk, Brest, Kamenets, Kleck, Slutsk, Gorodno, Haradok (later Davyd-Haradok, Zditov, Nobel, Dubrovitsa, Kapyl, Liahavichy, Sniatyn, Drohiczyn upon Bug and Vawkavysk. Therefore the eparchy encompassed the area from the Lower Beresina and Dnepr in the east to Bug (on the side of Prypiat in the west, from Kleck in the north to Lutsk, Dubrovitsa, Stepan and Chortoryisk in the south. For the principality of Turov it was the period of its greatest development and political importance. During that period first schools were founded, the art of icon painting developed as well as church architecture. Still the diocese of Turov depended too much on the political events. All political and Church changes influenced the situation in the principality of Turov.

    Full Text Available El trabajo se propone describir con cierto detalle el modo en que un texto ejemplar de la Edad Medía castellana "trabaja" ideológicamente. Para ello se analiza el capítulo XVI del Calda e Dimna, traducción alfonsí del árabe Kalila wa Dimna realizada entre 1251 y 1261, poniendo de relieve el tipo de subjetividad que el texto propone a su público para que, una vez asumido, pueda leerse el texto y situarse en el mundo.

La peculiar ubicación de la nobleza y de la naciente burguesía en el orden social diseñado por el texto, junto con la promoción de la figura regia por encima de la estructura estamental, revelan la filiación estrictamente alfonsí del sustento ideológico del Calila e Dimna.

  3. La «Renovatio Urbis» : poder, ciudad y universidad en el siglo XVI

    Full Text Available El proceso de renovación del concepto de Estado iniciado por los Reyes Católicos a finales del siglo xv, encontró en los medios institucionales el instrumento perfecto para dirigir y difundir sus nuevos principios doctrinales y poner en práctica sus programas de acción política. Las universidades, convertidas en instituciones puestas al servicio de la expresión del poder, encontraron a partir de entonces y a lo largo de todo el siglo xvi, un gran auge. Esta circunstancia se produce una vez que se toma conciencia desde el poder del valor que posee la educación como instrumento de acción política a partir del cual poder asegurar, como ha señalado J.A. Maravall, «la transmisión de los saberes que importan para la acción de gobierno», y en consecuencia, promover la renovación del Estado y de la sociedad

  4. Heat exchanger

    The arrangement described relates particularly to heat exchangers for use in fast reactor power plants, in which heat is extracted from the reactor core by primary liquid metal coolant and is then transferred to secondary liquid metal coolant by means of intermediate heat exchangers. One of the main requirements of such a system, if used in a pool type fast reactor, is that the pressure drop on the primary coolant side must be kept to a minimum consistent with the maintenance of a limited dynamic head in the pool vessel. The intermediate heat exchanger must also be compact enough to be accommodated in the reactor vessel, and the heat exchanger tubes must be available for inspection and the detection and plugging of leaks. If, however, the heat exchanger is located outside the reactor vessel, as in the case of a loop system reactor, a higher pressure drop on the primary coolant side is acceptable, and space restriction is less severe. An object of the arrangement described is to provide a method of heat exchange and a heat exchanger to meet these problems. A further object is to provide a method that ensures that excessive temperature variations are not imposed on welded tube joints by sudden changes in the primary coolant flow path. Full constructional details are given. (U.K.)

    A heat exchanger is designed for use in the transfer of heat between a radioactive fiuid and a non-radioactive fiuid. The exchanger employs a removable section containing the non-hazardous fluid extending into the section designed to contain the radioactive fluid. The removable section is provided with a construction to cancel out thermal stresses. The stationary section is pressurized to prevent leakage of the radioactive fiuid and to maintain a safe, desirable level for this fiuid. (AEC)

    An inner cylinder is disposed coaxially in a vertical vessel, and a plurality of heat transfer pipes are wound spirally on the outer circumference of the inner cylinder. High temperature sodium descends on the outer side of the inner cylinder while exchanging heat with water in the heat transfer pipes and becomes low temperature sodium. The low temperature sodium turns at the lower portion of the vessel, rises in a sodium exit pipe inserted to the inner cylinder and is discharged from the top of the vessel to the outside of the vessel. A portion of a cover gas (an inert gas such as argon) filled to the upper portion of the vessel intrudes into the space between the outer circumference of the sodium exit pipe and the inner circumference of the inner cylinder to form a heat insulation layer of the inert gas. This prevents heat exchange between the high temperature sodium before heat exchange and low temperature sodium after heat exchange. The heat exchanger is used as a secondary heat exchanger for coolants (sodium) of an FBR type reactor. (I.N.)

Las fundaciones más antiguas datan del siglo XVI, ya que debe recordarse que la incorporación de Canarias a la Corona de Castilla se produjo a lo largo de la centuria anterior. En cuanto a las órdenes, las más numerosas fueron las franciscanas (clarisas y concepcionistas con seis monasterios, a las que siguen las dominicas o catalinas y las bernardas, con cuatro, cada una, mientras las agustinas recoletas sólo poseyeron uno. La mayoría se pueden considerar urbanos o semiurbanos por el carácter de la ciudad o villa donde se emplazan, ocupando casi siempre las zonas más céntricas. Esta misma posición en la trama fue un factor decisivo en el momento de la desamortización, cuyas medidas provocaron la desaparición de la mayoría de los edificios, pasando los solares a ser ocupados por espacios libres (plazas y jardines, edificios público de nueva planta (ayuntamientos, teatros o construcciones privadas.

    2011-05-01

    We have performed large-scale CIV3 calculations of excitation energies from ground state for 69 fine-structure levels as well as of oscillator strengths and radiative decay rates for all electric-dipole-allowed and intercombination transitions among the fine-structure levels of the terms belonging to the (1s22s22p6)3s23p2, 3s3p3, 3p4, 3s23p3d, 3s23p4s, 3s23p4p, 3s23p4d, and 3s23p4f configurations of Cu XVI. These states are represented by very extensive configuration-interaction (CI) wave functions obtained with the computer code CIV3 of Hibbert. The important relativistic effects in intermediate coupling are incorporated by means of the Breit-Pauli Hamiltonian. Small adjustments to the diagonal elements of the Hamiltonian matrices have been made so that the energy splittings are as close as possible to the energy values of those from the National Institute for Standards and Technology. The mixing among several fine-structure levels is found to be very strong. From our radiative decay rates we have also calculated radiative lifetimes of the fine-structure levels. Our calculated lifetime for the high spin level 3s3p3(5S2) is found to be in excellent agreement with the experimental value of Trabert et al (1988 J. Opt. Soc. Am. B 5 2173). In this calculation, we also predict new data for several fine-structure levels where no other theoretical and/or experimental results are available. ).

    Anedda, Damiano

    2014-12-01

    Full Text Available Aquamaniles are tools that have a liturgical function in the Christian rite, the origins of which are likely to be linked to objects of profane use. This essay analyses the function and the types of the few examples that have survived to this day, dating from the eighth to the sixteenth century. These ornaments have a signifi cant position in the specialist historiography, having been considered by art historians to be “among the most artistic objects,” especially those produced in bronze. Bronze is the material used for the aquamanile in the shape of a peacock that is kept in the National Gallery in Cagliari. Subjecting this important object to historiographical and archival analysis, this study advances a formal comparison that suggests a chronological framework and a place of origin based on historical data.[it] Gli acquamanili sono degli utensili che hanno una funzione liturgica nel rito cristiano, le cui origini sono verosimilmente legate a oggetti di uso profano. Il saggio analizza la funzione e le tipologie dei pochi manufatti giunti ai giorni nostri, databili tra l’VIII e il XVI secolo. Queste suppellettili occupano una posizione particolare nella storiografi a specialistica, in quanto considerati dagli studiosi “tra gli oggetti più artistici”, principalmente nell’ambito dei bronzi. Di tale materiale è costituito l’acquamanile a forma di pavone musealizzato nella Pinacoteca Nazionale di Cagliari, per il quale si affronta un’analisi storiografica e d’archivio, si propongono dei confronti formali e si suggeriscono un inquadramento cronologico e un ambito di provenienza basato sui dati storici.

    2009-12-01

    Full Text Available RESUMEN: La victoria de la Casa de Habsburgo en las guerras de Italia (1494-1559 abrió un periodo de paz y seguridad en Italia. En el pasado, fueron muchos los historiadores que dibujaron un panorama sombrío de este periodo, que abarcó los siglos XVI al XVIII. Fueron dos siglos descritos como un tiempo oscuro que sucedió a la brillantez del Renacimiento. Despotismo, Contrarreforma e intolerancia reemplazaron a la libertad, reformismo y tolerancia preexistentes. Su responsable fue la dominación española. Hoy, esa vieja interpretación está siendo revisada por una nueva generación de historiadores que describen el periodo en otros términos. El dominio español es contemplado como un condominio, un dominio dual o coparticipado entre la Corte española y las Cortes italianas o, mejor dicho, entre las élites españolas e italianas. Esta perspectiva explica el sistema español tanto para comprender su éxito como su hundimiento.ABSTRACT: The victory of the Habsburg Army in the Italian Wars (1494-1559 opened a time of peace and security in Italy. Many historians draw a negative panorama of this new period from sixteenth to early eighteenth centuries. So, these two centuries, were traditionally described as a Dark Age before the splendid time of the Renaissance. Despotism, Counterreformation and Intolerance replace Liberty, Reform and Tolerance. The Spanish dominion was responsible of this falling back. Today this old interpretation is revised by new generations of historians that describe the period in other terms. The Spanish dominion is sawn in a different way, as condominium, dual control or ownership between the Spanish Court and the Italian Courts, between Spanish and Italian elites. This point of view explains the Spanish System, his success and his breakdown.

    Full Text Available RESUMEN: El negro, como libre o como esclavo, fue un componente más de la sociedad española del siglo XVI. Como miembro de la misma estuvo sometido al control de las instituciones religiosas y políticas y, si era esclavo, fue un simple objeto de la voluntad de sus dueños. La Inquisición también le persiguió, y aunque éste no tenía una personalidad jurídica definida, fue considerado como persona con una formación religiosa adecuada y, por eso, juzgado por los responsables inquisitoriales. Hacemos aquí una primera aproximación en esta peculiar relación e insistimos en que los procesos inquisitoriales son también una fuente útil para estudiar ciertos aspectos y circunstancias de la vida del negro en aquella época.ABSTRACT: The Negro, as a free man or as slave, was an additional component in Spanish society during the 16th century. As member of this society he was subjected to the control of the political and religious institutions and if he was a slave, he was simply at the disposal of his master's will. The Inquisition also persecuted him and although he didn't have an officially recognized status, he was considered to be as person with a suitable religious grounding and was therefore judged accordingly by those in charge of the Inquisition. Here we approach this peculiar relationship for the first time and we emphasize that the inquisitorial trials are also an useful source enabling us to study certain aspects and circumstances in the Negro's life at that time.

    Hydrogen exchange (HX) monitored by mass spectrometry (MS) is a powerful analytical method for investigation of protein conformation and dynamics. HX-MS monitors isotopic exchange of hydrogen in protein backbone amides and thus serves as a sensitive method for probing protein conformation...... and dynamics along the entire protein backbone. This chapter describes the exchange of backbone amide hydrogen which is highly quenchable as it is strongly dependent on the pH and temperature. The HX rates of backbone amide hydrogen are sensitive and very useful probes of protein conformation......, as they are distributed along the polypeptide backbone and form the fundamental hydrogen-bonding networks of basic secondary structure. The effect of pressure on HX in unstructured polypeptides (poly-dl-lysine and oxidatively unfolded ribonuclease A) and native folded proteins (lysozyme and ribonuclease A) was evaluated...

    A heat exchanger such as forms, for example, part of a power steam boiler is made up of a number of tubes that may be arranged in many different ways, and it is necessary that the tubes be properly supported. The means by which the tubes are secured must be as simple as possible so as to facilitate construction and must be able to continue to function effectively under the varying operating conditions to which the heat exchanger is subject. The arrangement described is designed to meet these requirements, in an improved way. The tubes are secured to a member extending past several tubes and abutment means are provided. At least some of the abutment means comprise two abutment pieces and a wedge secured to the supporting member, that acts on these pieces to maintain the engagement. (U.K.)

Les chroniqueurs et historiens des XVIe, XVIIe et XVIIIe siècles ont délaissé cette région, attirés par les monuments et les richesses fabuleuses du Cuzco. Cependant, s'il y a absence quasi totale de chroniques sur les Tallán, Mochica et Chimus, il est certain qu'il existe d'autres moyens pour connaître leurs cultures matérielles et spirituelles, tels que les 'visites' et autres documents. C'est ainsi que l'on arrive à découvrir aujourd'hui les peuples protohistoriques et historiques qui ont vécu dans ce qui est actuellement le département de Lambayeque, la province de Pacasmayo et la vallée du Chicama, siège du royaume inconnu des Mochica qui se développa entre les XIIIe et XVIIe siècles sous une forme très différente de la culture archéologique et préhistorique de Moche. On démontre ici que rattacher à la 'Culture Mochica' les créatures des superbes vases-portraits est aussi faux que de rattacher à la 'Culture Aymara' les fondateurs de Chavin. En effet, les Mochica formèrent une société protohistorique et historique dont l'origine remonte au début du XIIIe siècle et qui a persisté jusqu'au milieu du XVIIe siècle.

    International Nuclear Information System (INIS)

    Dias, M. I.

    2016-01-01

    A case study concerning an ongoing project of an archaeometric study of ceramic materials from the XVI to the first half of the XVIII century - early Portuguese faience (XVII – 1st half XVIII cent.), and from Chinese porcelain ordered for the Portuguese market (XVI-XVII cent.) is presented. The general aspects to be considered in both cases are related with chronology precision, identification and differentiation of production centers and technologies of ceramic production, and characterization of surface coatings (glazes and pigments). This research project is being carried out on glazed faience and porcelain fragments collected during recent archaeological excavations from Portugal (Lisbon and Coimbra) by applying both laboratory techniques - X ray fluorescence spectrometry and X ray diffraction, instrumental neutron activation analysis - and X ray absorption spectroscopy using synchrotron radiation at the European Synchrotron Radiation Facility in Grenoble/France. The obtained results point to a clear chemical differentiation of Coimbra and Lisbon faience productions, and the definition of two compositional groups for Lisbon. Regarding porcelains, a trend of two large chemical groups is observed, which may reflect the two major porcelain producing regions of China, Jingdezhen (Jiangxi Province) and Zhejiang. After the compositional studies of both paste and surface finishing of faience and porcelains, considering the importance of blue pigments in these XVI-XVII century glazes, the blue chromophore role of cobalt in the glazes was also studied and discussed in relation to the speciation state and coordination environment of this element within the glassy silicarich matrix of both faience and porcelains. The results obtained of both near-edge and extended fine structure analysis of Co 1s XAFS spectra point to the expected valence state (2+) of cobalt ions hosted as glass-forming components with an average coordination number close to four and a mean Co

    Full Text Available ResumenEl sector al que correspondió el mayor protagonismo dentro de la industria europea moderna fue, sin lugar a dudas, el textil. Ello no representaba, en realidad, novedad alguna, pues la industria medieval se desarrolló precisamente en función primordialmente de la fabricación de tejidos. El vestido, al tiempo que una necesidad inmediata, resulta expresión visual de distinción social, aún más que la decoración de la vivienda. Por ello la industria textil creció a expensas tanto de la necesidad como del lujo. Uno de los grandes cambios que se producen en este tipo de industria durante todo el siglo XV y se consolida en el XVI se centra en las relaciones de producción, en la utilización de mano de obra campesina y la consolidación del ciclo de producción artesano rural. La mano de obra rural comienza a trabajar por su cuenta o en dependencia del empresario-productor de la ciudad. Si bien, la profunda transformación de la industria textil tendrá lugar en el siglo XVIII, con la revolución industrial.La transformación de la industria textil del siglo XVI propició la expansión de una nueva figura en el ámbito mercantil, que se denomina mercader-empresario, y por tanto, del sistema doméstico de producción conocido como Verlagssystem. Este nuevo sistema implicará modificaciones de factores claves para el desarrollo de las futuras sociedades mercantiles como pueden ser: el capital, la utilización de la materia prima y su proceso de transformación, la formación de los costes de producción y comercialización, la obtención de beneficios y su distribución, la concentración del capital y la generación de rentes. En definitiva, la creación de una nueva clase social, la burguesía. Este trabajo se centra en la industria sedera de la ciudad de Toledo en el siglo XVI.AbstractThe textile sector, was the greater protagonist, without doubt, within the modern European industry.

Therefore, this paper will focus on some morphological changes observed in the apostle’s attribute, from the 11th to the 16th century in Western Europe, which are related to certain technical improvements in the textile trade, as well as to some lexical, social and psychological factors.La imagen del apóstol Santiago el Menor constituye un buen ejemplo que permite analizar los distintos avatares que provocaron cambios iconográficos en el emblema del martirio del apóstol, desde el siglo XI y hasta el XVI en Europa occidental, relacionados a su vez con ciertas innovaciones técnicas de los instrumentos de trabajo del oficio textil, así como con factores de carácter léxico, social y psicológico.

    Full Text Available El delito de proposiciones consistía en las expresiones que refl ejaban puntos contrarios con la doctrina de la Iglesia católica. Por ello, pertenecía a la jurisdicción del Santo Ofi cio, que recibió denuncias incluso contra el clero por cometer esta transgresión, sobre todo durante los sermones, por lo que se cree que causaban confusión entre los oyentes. Pero ¿realmente provocaban escándalo entre la población o solo entre los eclesiásticos?, ¿acaso se trataba de errores de entendimiento por la poca instrucción de los predicadores?, o ¿se usaba el púlpito para expresar los confl ictos de la Iglesia? A estas preguntas se les dará respuesta en este texto, que se ubica en Zacatecas en los siglos XVI y XVII.

    Full Text Available La monarquía de los Austrias, como es de sobra conocido, topó con enormes dificultades en el gobierno de los estados de la Corona de Aragón. Los fueros y libertades de los distintos territorios impedían un ejercicio efectivo de la autoridad real y ello fue particularmente acusado en los casos del principado catalán y del reino aragonés. Por lo que a Aragón se refiere, el esquema de la modernidad podría resumirse del modo siguiente: frente a un siglo XVI en que el reino puso todo tipo de trabas al ejercicio de la autoridad real, en la centuria del seiscientos la monarquía había vencido cualquier resistencia y podía gobernar con la aquiescencia de la clase dirigente aragonesa.

It has been carried out through the study of historical toponymy from several 16th and 18th-century documents and their contrast with modern cartography (MTN25 and MTN50. Together with a methodology for the development of landscape analysis based on the use of GIS, we submit an estimation of the whole dehesas surface (108,511.87 ha and their sheep stocking rate average (0.28 UGM for the analyzed period. The results retrieved question the livestock orientation of these spaces as a consequence of soil deficiencies. Instead of this, the article concludes that dehesas landscape is related to the jurisdictional model developed in the Estates of the Military Order of Alcantara during the Middle Ages.Presentamos en este artículo una cartografía del espacio ocupado por las dehesas maestrales de la Orden de Alcántara en La Serena (Badajoz durante los siglos XV-XVIII.

    Carl Wilhelm Naundorff was buried in 1845 in Delft as Louis Charles, Duc de Normandie, 'Louis XVII'. However, the son of Louis XVI and Marie-Antoinette-Louis XVII--officially died in the Temple of Paris in 1795. In order to resolve the identity of Naundorff, mitochondrial DNA (mtDNA) D-loop sequences of his remains were compared with the sequences obtained from the hairs of two sisters of Marie-Antoinette, Marie-Antoinette herself, and with the sequences obtained from DNA samples of two living maternal relatives. The mtDNA sequence of a bone sample from Naundorff showed two nucleotide differences from the sequences of the three sisters and four differences from the sequences of living maternal relatives. Based on this evidence it becomes very unlikely that Naundroff is the son of Marie-Antoinette.

    In well over half of the individuals with rare disease who undergo clinical or research next-generation sequencing, the responsible gene cannot be determined. Some reasons for this relatively low yield include unappreciated phenotypic heterogeneity; locus heterogeneity; somatic and germline mosaicism; variants of uncertain functional significance; technically inaccessible areas of the genome; incorrect mode of inheritance investigated; and inadequate communication between clinicians and basic scientists with knowledge of particular genes, proteins, or biological systems. To facilitate such communication and improve the search for patients or model organisms with similar phenotypes and variants in specific candidate genes, we have developed the Matchmaker Exchange (MME). MME was created to establish a federated network connecting databases of genomic and phenotypic data using a common application programming interface (API). To date, seven databases can exchange data using the API (GeneMatcher, PhenomeCentral, DECIPHER, MyGene2, matchbox, Australian Genomics Health Alliance Patient Archive, and Monarch Initiative; the latter included for model organism matching). This article guides usage of the MME for rare disease gene discovery. © 2017 by John Wiley & Sons, Inc. Copyright © 2017 John Wiley and Sons, Inc.

    Full Text Available Estudio relativo a la política desarrollada por el Concejo de Zaragoza sobre el mercado de carne durante los siglos XVI y XVII. La prosperidad económica del reino de Aragón, la ciudad y municipio de Zaragoza durante el siglo XVI permitieron aumentar el control público sobre las transacciones de carne para asegurar a la población un suministro suficiente, así como sustentar la demanda local. Sin embargo, el declive económico del reino de Aragón y el creciente endeudamiento municipal durante el siglo XVII obligaron a reducir la presencia pública en el mercado y la defensa de la demanda local en el mercado de carne. El reajuste de la política municipal promovió la paulatina integración del mercado aragonés, proceso que continuó en el siglo XVIII para afianzarse durante la crisis final del Antiguo Régimen.This paper studies municipal politics carried out by the Zaragoza city council concerning the meat market during the sixteenth and seventeenth centuries. Economic prosperity in the kingdom of Aragón, Zaragoza city and council during the sixteenth century allowed to increase public control of meat transactions in order to supply efficiently the population, as well as to support local demand. However, economic decline of the kingdom and raising municipal indebtedness during the seventeenth century led to reduce public intervention and support of local demand on the meat market. Readjustment of municipal politics gradually promoted the integration of the market in Aragón. This process continued during the eighteenth century and became firmly established during the final crisis of the "Ancien Régime".

    Full Text Available El propósito de este artículo es examinar el sistema de remuneración del clero en la catedral de Toledo en el siglo XVI. Su cabildo mantenía un sistema basado en las enseñanzas bíblicas y la normativa conciliar. Existía así una relación directa entre la remuneración de los sacerdotes y su misión de culto. Esto permitió establecer un salario justo en función a la presencia de los beneficiados a los oficios divinos y a las horas canónicas. Además, el cabildo garantizaba la correcta ejecución de este sistema retributivo a través de importantes mecanismos de control, apuntando de forma rigurosa las ausencias o irregularidades en el culto, que eran penalizadas a cuenta de su asignación y repartidas entre los beneficiarios cumplidores.The purpose of this articte is to explore the system of remuneration to priest on the cathedral of Toledo in the XVI century. Its chapter kept a system based on the biblical preaching and the canons of the ecclesiastical councils. There was thus a plug between the remuneration of the priest and their mission of cult to God. The belief system was a key factor to set an exact salary that was based on the presence of prebendaries at the divine offices and the canonical hours. Furthermore, the chapter kept an effective control system to report about the absences or irregular behaviour in the cult that were penalized. Then, on based to this information, it was set the salary. The fines were distributed to the prebenderies that fulfilled their obligations.

    resulted in crop damage and famine. From the XIV century the little Ice Age began. Year average temperature becomes lower by 1.4°C and summer temperature - by 2-3°C. In the XIV century the chronicles mentioned a total of 100 extreme natural phenomena, as a result of which Russia experienced more than 37 years of famine. The climate was particularly variable in late XIV - early XV century and XVI - XVII centuries, when there were years of particularly cold winters and increased humidity (due to winter precipitation). The duration of the crop growing season was reduced by three weeks. At the beginning of the XVII century spruce became dominant in the spruce-deciduous forests and co-dominant in deciduous forests. There was a transfer of settlements and agricultural land to interfluve areas and higher river valleys. The determining factors were demographic, socio-economic and historical factors, but the role of natural factors cannot be overlooked. The end of the XVI century was marked by the most severe political and economic crisis in the Russian State (oprichnina (political and administrative apparatus established by Ivan IV) and Livonian Wars by Ivan IV), which, combined with deteriorating environmental conditions (increased humidity of the climate, the average annual temperature drop) caused massive desolation of the lands. Many hundreds of villages turned into wasteland. In this period the Moscow land was reported as a "wild desert, covered with shrubs, bogs and imbanks", there were also memories of the past navigation on small rivers, data on mills on the streams. The climate deterioration caused the agrarian revolution in Russia in XIV-XVI centuries. Slash-and-burn and shifting cultivation was replaced by plow farming system (two- and three-field), which was more adapted to the harsh climatic conditions.

    Full Text Available A través de este texto se pretende dar a conocer cómo las rutas de circulación de sal en la Provincia de Tunja contribuyeron a configurar un gran espacio económico, que integró a las provincias de Santa Fe, Pamplona y Tunja en el Nuevo Reino de Granada, durante el siglo XVI. Se partió de una reflexión historiográfica relacionada con la circulación y el comercio de la sal, los medios de transporte y las rutas usadas por los indígenas y los españoles; a partir de las cuales se consolidó un espacio económico mediado por la producción y distribución de la sal, que convirtió a la provincia de Tunja en un eje articulador de relaciones entre los sitios productores de sal en la provincia de Santa Fe y los consumidores de las provincias de Tunja y Pamplona. Esta articulación regional facilitó tanto la circulación de productos de distintos pisos térmicos, como la integración de un amplio territorio colonial. Esto debido a que la localización de Tunja como lugar de paso y conexión entre las Provincias de Santafé, Pamplona y los Llanos de San Juan, hizo de esta ciudad y sus términos un atractivo para el asentamiento hispano, a la vez que generó, durante la segunda mitad del siglo XVI, la posibilidad para que se organizaran en toda la Provincia de Tunja, sitios de aposento, venta y reventa de productos importados de España y productos de la tierra, para el sustento y abastecimiento de las necesidades básicas, y de esta forma sacar provecho de las producciones locales como la sal, el hayo, el algodón, las mantas y otros productos.

    Full Text Available Se presenta en este artículo la investigación realizada sobre un tipo concreto de documentos de aplicación práctica del derecho relacionados con las sucesiones mortis causa, los codicilos. Sobre la base de un grupo de 30 codicilos valencianos de los siglos XV y primeros años del XVI, se sistematiza la orientación de las diversas modificaciones que estos documentos introdujeron sobre testamentos anteriores, de forma que es accesible la valoración de las cuestiones que resultaron de mayor interés para los testadores, apareciendo resultados que sugieren la idea de predominio de una mentalidad práctica por encima de las cuestiones directamente relacionadas con el mundo espiritual.Our research focuses on a particular type of document, the codicil, which involves a practical legal application of inheritance upon death. We use a group of thirty Valencian codicils of the fifteenth and earl ysixteenth centuries in order to categorize the manifold modifications that these documents introduced in previous wills. The result is a more accessible assessment of the issues that were of most interest to the testers, which leads one to suggest the idea of a practical mind-set prevailing over issues directly related to the spiritual realm.

    Full Text Available This article tries to achieve an approach to the role of Inquisition in Spanish presidios of North Africa during XVIth and XVIIth centuries. Although no one of these enclaves had its own court —only Oran had it from 1516 until 1536— and they depended on peninsular courts, in all of them were kept watch the religious orthodoxy. The suspects of being moslem were quite common, but papers prove how the purpose of these courts were to assimilate the acussed into his religious and cultural previous world.

    Este artículo pretende realizar una aproximación al papel de la Inquisición en las plazas españolas del norte de África durante los siglos XVI y XVII. Aunque ninguna de ellas tuvo un tribunal propio —excepto Orán entre 1516 y 1536— y tuvieron que depender de los tribunales peninsulares más próximos en cada caso, todas ellas vieron vigilado el cumplimiento de la más estricta ortodoxia religiosa. Los casos de islamismo fueron, de forma lógica, los más frecuentes y perseguidos por el Santo Oficio, pero los documentos analizados demuestran que la prioritaria finalidad de los tribunales es la de reinsertar a los acusados en su antiguo mundo religioso y cultural, por encima del delito que hayan cometido.

    Full Text Available The article considers the problems related to the peculiarities of the Russian state political and legal development during the early New Time (XVI-XVII centuries in a comparative-historical aspect against the background of similar processes taking place in neighboring European states. The authors come to the conclusion that, despite certain, dictated by objective reasons (first of all, the conditions for the emergence and subsequent development, there are more common features than the differences between the processes of the political and legal sphere development in Russia and Western Europe. The fact that this community escaped from the view of researchers is related, in the authors' opinion, to the fact that foreign observers, describing the political system of an early Russian state, dealt only with an outer shell, while its internal contents remained if not a secret, then, in any case, a mystery for them. They were not admitted to the Russian political cuisine, and therefore the details of Russian political and legal institution functioning remained unavailable to them.

Angel Rodríguez comprende muy bien que el mundo aldeano peninsular vivía su propio tiempo y circunstancia. La inquisición actuó junto a esta otra inquisición, que se sirvió del rumor, la envidia, el odio, el rencor y, probablemente, el deseo de venganza. Hubo confesiones sinceras, honestas, es cierto. Pero, la máquina del miedo estaba aceitada. Las delaciones sirvieron para inquietar y fabricar manuales que regularan y transformaran la vida de los clérigos.

    Full Text Available Tunja has stood out as one of the riches cities of New Kingdom of Granada, regarding the presence of painting in the last decades of the XVI century and the first half of the XVIIth. Its painters were of importance not only in this city but in the rest of the Province as well, with the churches and museums of Boyacá containing images that were essential elements in the indoctrination of indigenous communities. Civil mural works of art in Tunja have been an object of study mostly for their interpretation, and less regarding the identities of their makers. As far as easel painting, Angelino Medoro eclipsed the names of other artists who contributed to making Tunja one the the most representative cities of the Mannerism and Renaissance of Hispanic America. This article presents the names of some of the active painters of this period, their lives and production, seeking the recognition of these characters, whose names have been brought out of anonymity in the latest years. The starting point for the information search was the research of Magdalena Corradine Mora on the inhabitants of Tunja in the first decades of the XVII century, and the search for information in the Boyacá Regional Historical Archive. In calling attention upon these artists, we hope that, in the future, the identification of their works may be initiated as well as the research, conservation and dissemination of these works, due to the fact that this heritage is not always in ideal conditions, nor is it perceived and valued as is deserved.

A través de las fiestas celebradas en las casas de la nobleza, del empleo del espacio natural como improvisado marco festivo, o de la integración más o menos artificiosa de la naturaleza en el espacio urbano, ésta se convierte en gran teatro de la Corte, aportando interesantes peculiaridades al modo en que la relación entre fiesta, naturaleza y ciudad se desarrolló en los siglos XVI y XVII.During the Renaissance and Barroque periods, gardens and festivities be inspired in the similar artistic and literary referencies and following de same evolution and expresión's systems.

    Full Text Available In the second half of the XVI century Moscow state, defeating Kazan (1552 and Astrakhan (1556 khanate, came to the Caspian sea to the North Caucasus, where he encountered opposition from two very strong opponents: Turkey and the Crimean khanate. The Ottoman Empire, which included Northern Caspian and the Caucasus in the number of its geopolitical interests, sought power and diplomatic means to subdue the mountain and nomadic population, their power and actively opposed their rapprochement with Russia. One of the main performers and conductors of Turkish policy in the region were dependent vassal of Turkey, the Crimean khanate. The peoples of the North Caucasus, first of all Nogai, the Kabardians and the representatives of several other Circassian tribes, seen in Moscow state protection from the expansive aspirations of the Crimea and Turkey and actively supported the Russian fortification construction and anticrime military operations of the Russian North Caucasus. Military and diplomatic successes of the Russian state in the North Caucasus and the Caspian sea in the second half of the XVI century contributed to the development of international Eastern trade along the Volga-Caspian route and the strengthening of the authority of Moscow in the region and in the international arena.

    Full Text Available La idea de un nuevo Flandes o de un segundo Flandes o simplemente de otro Flandes apareció en diferentes momentos en el territorio de la Monarquía Hispánica referida a Aragón, Cataluña o Messina. El recuerdo de la guerra pervivió en el imaginario colectivo español más allá del final del conflicto, cuando Flandes era ya un aliado de la Corona española frente a Francia. Cuando en el desarrollo de la conquista de las Indias Occidentales Chile se convierte en el gran problema militar con motivo de la resistencia de los indígenas de la Araucanía, la idea de un segundo Flandes aparecerá también en tierras americanas. Este trabajo pretende mostrar el proceso y los contextos en que Flandes se hizo presente en el discurso que se elaboró sobre el Reino de Chile en las crónicas de los siglos XVI y XVII, hasta que Diego de Rosales acuñara el término “Flandes indiano”. The idea of a new Flanders or of a second or simply of another one appeared in different moments in the territory of Hispanic Monarchy referred to Aragón, Catalonia or Messina. The memory of this war survived in the Spanish collective imaginary even long after the end of the conflict, when Flanders was an ally of the Spanish Crown against France. When Chile becomes the great military problem due to native resistance to conquest, the idea of a second Flanders will turn up in America. This article tries to show the process and contexts in which Flanders becomes visible in the discourse elaborated around the kingdom of Chile in the chronicles of 16th and 17th Centuries, until Diego de Rosales, the first writer to use the term “Indian Flanders”.

    Full Text Available We have selected some questions of military historiography from XVIth to XVIIIth century according to their influence on the global comprehension of the early modern history. From this subject we have evaluated dificulties and goals in the last decades. We have specially paid attention to the British and French historiographycal traditions because of their development and significance on the Spanish way of facing the military history. In conclution, we suggest that the main methodological and conceptual contributions of the special field that concerns us in this article have to be related to the last years. This matched with the moment in which these historians have changed their attempt to focus the most important changes in the early modern period from their specialism. Best results have been achieved when they have recognized a more modest status for the military history.

    Dentro del campo de la historiografía militar —en un sentido amplio— de los siglos XVI al XVIII, se han seleccionado algunas cuestiones que por su influencia e innovación conceptual han supuesto mayores aportaciones a la comprensión general del período moderno en su conjunto. A partir de ellas, se ha tratado de valorar los principales logros y los escollos más enconados que los historiadores de la especialidad han ido ofreciendo y encontrando en las últimas décadas. Las escuelas historiográficas de lo militar que, en función precisamente de su desarrollo, han encontrado mayor cabida en estas páginas son la británica y, en menor medida, la francesa. Ambas, por otro lado, son las que más han influido en los historiadores españoles. Como conclusión, el autor sugiere que las principales aportaciones metodológicas y conceptuales de la historiografía militar modernista se han producido precisamente en el momento en el que se ha abandonado la pretensión de hacer de lo específicamente militar el factor clave en el desarrollo histórico de las sociedades

    1989-10-01

    An automated blood exchange transfusion (BET) with a two-site technique has been devised by Goldmann et al and by us, using an infusion pump. With this method, we successfully performed exchange transfusions 189 times in the past four years on 110 infants with birth weights ranging from 530 g to 4,000 g. The exchange rate by the automated method was compared with the rate by Diamond's method. Serum bilirubin (SB) levels before and after BET and the maximal SB rebound within 24 hours after BET were: 21.6 +/- 2.4, 11.5 +/- 2.2, and 15.0 +/- 1.5 mg/dl in the automated method, and 22.0 +/- 2.9, 11.2 +/- 2.5, and 17.7 +/- 3.2 mg/dl in Diamond's method, respectively. The result showed that the maximal rebound of the SB level within 24 hours after BET was significantly lower in the automated method than in Diamond's method (p less than 0.01), though SB levels before and after BET were not significantly different between the two methods. The exchange rate was also measured by means of staining the fetal red cells (F cells) both in the automated method and in Diamond's method, and comparing them. The exchange rate of F cells in Diamond's method went down along the theoretical exchange curve proposed by Diamond, while the rate in the automated method was significantly better than in Diamond's, especially in the early stage of BET (p less than 0.01). We believe that the use of this automated method may give better results than Diamond's method in the rate of exchange, because this method is performed with a two-site technique using a peripheral artery and vein.

    2015-01-01

    Introduction Quality assurance of the image quality for image guided localization systems is crucial to ensure accurate visualization and localization of target volumes. In this study, the long term stability of selected image parameters was assessed and evaluated for CBCT mode, planar radiographic kV mode and MV mode. Methods and Materials: The CATPHAN, QckV-1 and QC-3 phantoms were used to evaluate the image quality parameters. The planar radiographic images were analyzed in PIPSpro™ with spatial resolution (f30, f40, f50) being recorded. For XVI CBCT, Head and Neck Small20 (S20) and Pelvis Medium20 (M20) standard acquisition modes were evaluated for Uniformity, Noise, Spatial Resolution and HU constancy. Dose and kVp for the XVI were recorded using the Unfors RaySafe Xi system with the R/F Low Detector for the kV planar radiographic mode. Results A total of 20 and 10 measurements were acquired for the planar radiographic and CBCT systems respectively over a two month period. Values were normalized to the mean and the standard deviations (STD) were recorded. For the planar radiographic spatial resolution, the STD for f30, f40, f50 were 0.004, 0.002, 0.002 and 0.005, 0.007, 0.008 for the kV and MV, respectively. The average recorded dose for kV was 38.7±2.7 μGy. The STD of the evaluated metrics for the S20 acquisition were: 0.444(f30), 0.067(f40), 0.062(f50), 0.018(Water/poly-HU constancy), 0.028(uniformity) and 0.106(noise). The standard deviations for the M20 acquisition were: 0.108(f30), 0.073(f40), 0.091(f50), 0.008(Water/poly-HU constancy), 0.005(uniformity) and 0.005(noise). Using these, tolerances can be reported as a warning and action threshold of 1σ and 2σ. Conclusion A study was performed to assess the stability of the basic image quality parameters recommended by TG-142 for the Elekta XVI and iView imaging systems. Consistent imaging and dosimetric properties over the evaluated time frame were noted. This work was funded in part by the Cancer

With the enactment of the Law of Ukraine "About the condemnation of the Communist and national socialist (Nazi totalitarian regimes in Ukraine and the prohibition of propaganda of their symbolism", by minimum historical counting, about 800 localities of which at least 24 cities including Dnipropetrovs’k need to be renamed. But the views of residents of the city are divided: some support to keep the old name of the city, changing its semantic load, and there are a lot of people willing to rename the city in Sicheslav, Dniproslav, Kodak and the like. Now it is important to know the opinion of young people in the city and region who create their future and that of their children. The analysis of the research. The history of the settlements of the XVI – XVIII centuries on the territory of the future Katerynoslav (Dnipropetrovs’k became the subject of study of many scientists since the nineteenth century. In the years of independence more and more historians declare the necessity of the revision of the chronology of the history of our city, taking into account the earlier settlements, which undoubtedly influenced both the development of the region and the future provincial city. The purpose of this article is to determine the degree of influence of the settlements of the XVI – XVIII centuries on later (including modern history of Katerynoslav (Dnipropetrovs’k in the minds of the youth of the city. Conclusion. The analysis of the settlements of the XVI-XVIII centuries testifies to the active urban processes that took place in our region in the Cossack-Hetman days. This important stage in the history of our city enriches us, its current inhabitants, with facts about the distant past which we should not only remember and pass on to our descendants, but also recover through the reconstruction of the defining architectural features.

    Full Text Available În secolele XV-XVI, în Ţările Române au circulat diverse lucrări conţinând vise şi vedenii profetice. O categorie importantă de vise profetice, răspândită prin intermediul surselor bizantine şi sud-slave, o constituia visul monarhic care prevestea naşterea, cariera politică sau moartea suveranului. În lucrările istorice, visele de acest gen puteau reprezenta procedee de critică sau legitimare a puterii suveranului. Tradiţia viselor profetice, asociate suveranului, a avut continuitate în spaţiul românesc, având în centru figurile câtorva domni ai Ţării Moldovei (Ştefan cel Mare, Alexandru Lăpuşneanu, Petru Şchiopul, relatări atestate în textele narative medievale. În comparaţie cu visele, survenite în timpul somnului, vedeniile surveneau în stare de veghe şi, potrivit surselor examinate, din Ţările Române, evocau în special probleme ale vieţii spirituale.PROPHETICAL DREAMS AND VISIONS IN MANUSCRIPTS FROM THE ROMANIAN PRINCIPALITIES (XV-XVI C. During the XV-XVI c., in the Romanian Principalities has circulated a rich literature dedicated to prophetic dreams and visions. An important category of prophetical dreams, being presented in the Byzantine and South-Slavonic sources, was the monarchic dream that anticipated the birth, the political carrier or death of the sovereign. In the historical works, such dreams could represent means of criticising or legitimating the sovereign’s power. The tradition of prophetic dreams assigned to sovereigns was continued in the Romanian area, being centred on the figures of several princes of Moldova (Ştefan cel Mare, Alexandru Lăpuşneanu, Petru Şchiopul. In contrast with dreams, that occurred while sleeping, visions took place while awake and, according to the Slavonic manuscripts from the Romanian Principalities, revealed mainly issues of spiritual life.

    The objective of this research is to develop tools to design and optimize heat exchangers (HE) and compact heat exchangers (CHE) for intermediate loop heat transport systems found in the very high temperature reator (VHTR) and other Generation IV designs by addressing heat transfer surface augmentation and conjugate modeling. To optimize heat exchanger, a fast running model must be created that will allow for multiple designs to be compared quickly. To model a heat exchanger, volume averaging theory, VAT, is used. VAT allows for the conservation of mass, momentum and energy to be solved for point by point in a 3 dimensional computer model of a heat exchanger. The end product of this project is a computer code that can predict an optimal configuration for a heat exchanger given only a few constraints (input fluids, size, cost, etc.). As VAT computer code can be used to model characteristics (pumping power, temperatures, and cost) of heat exchangers more quickly than traditional CFD or experiment, optimization of every geometric parameter simultaneously can be made. Using design of experiment, DOE and genetric algorithms, GE, to optimize the results of the computer code will improve heat exchanger design.

    2014-01-01

    Full Text Available The paper considers the use of infinitives and subjunctive forms as modal patterns of indirect speech attested in Russian Chronicles of the XI—XVI centuries. In early texts, an infinitive in a subordinate clause describes either a speech act that must be put into practice or a situation destined to happen. Subjunctive forms are used only in citations containing requests. The illocutionary power of reported speech is regularly marked with an illocutionary verb. In later chronicles, infinitive clauses and subjunctive forms begin to alternate in modal patterns of indirect speech containing official orders. However, the modal patterns are not yet attested as a substitute of imperative mood in subordinate clauses.

    Full Text Available En este trabajo los autores analizan el uso del color en las estrategias de persuasión política que utilizan los partidos y los candidatos durante los procesos electorales. También se describe la utilización que los principales partidos políticos de México hacen de los colores para lograr un posicionamiento y una diferenciación política. Específicamente, se indaga sobre el uso del color en los XVI Juegos Panamericanos celebrados en Guadalajara en octubre del 2011. Por ejemplo, se señala que el azul fue el color preponderante en la decoración de las instalaciones deportivas, los hoteles de la ciudad, los automóviles oficiales y en la publicidad del evento, lo que formaba parte de una estrategia ante las próximas elecciones federales del 2012.

  6. Standardizing exchange formats

    International Nuclear Information System (INIS)

    Lemmel, H.D.; Schmidt, J.J.

    1992-01-01

    An international network of co-operating data centres is described who maintain identical data bases which are simultaneously updated by an agreed data exchange procedure. The agreement covers ''data exchange formats'' which are compatible to the centres' internal data storage and retrieval systems which remain different, optimized at each centre to the available computer facilities and to the needs of the data users. Essential condition for the data exchange is an agreement on common procedures for the data exchange is an agreement on common procedures for the data compilation, including critical data analysis and validation. The systems described (''EXFOR'', ''ENDF'', ''CINDA'') are used for ''nuclear reaction data'', but the principles used for data compilation and exchange should be valid also for other data types.

    This work treats about the professions related with the fishing in the Kingdom of Toledo, in the high and middle course of river Tagus, from XII-XVIth centuries. Along these pages we have seen many different kind of people, public servants, great merchants, workers of the fisheries, involved in the fishing, trading and delivering of fish in this time. So with this article, we break with the idea which identified the fishing only with fishing men and boats showing how the medieval society was interested in every economic activity which produced profits.

Con este artículo, queremos romper con la idea que identifica la pesca sólo con los pescadores y los barcos, mostrando como la sociedad medieval se interesaba en cualquier actividad económica que produjese beneficios.

  8. Evaluating the accuracy of the XVI dual registration tool compared with manual soft tissue matching to localise tumour volumes for post-prostatectomy patients receiving radiotherapy

    Cone beam computerised tomography (CBCT) enables soft tissue visualisation to optimise matching in the post-prostatectomy setting, but is associated with inter-observer variability. This study assessed the accuracy and consistency of automated soft tissue localisation using XVI's dual registration tool (DRT). Sixty CBCT images from ten post-prostatectomy patients were matched using: (i) the DRT and (ii) manual soft tissue registration by six radiation therapists (RTs). Shifts in the three Cartesian planes were recorded. The accuracy of the match was determined by comparing shifts to matches performed by two genitourinary radiation oncologists (ROs). A Bland–Altman method was used to assess the 95% levels of agreement (LoA). A clinical threshold of 3 mm was used to define equivalence between methods of matching. The 95% LoA between DRT-ROs in the superior/inferior, left/right and anterior/posterior directions were −2.21 to +3.18 mm, −0.77 to +0.84 mm, and −1.52 to +4.12 mm, respectively. The 95% LoA between RTs-ROs in the superior/inferior, left/right and anterior/posterior directions were −1.89 to +1.86 mm, −0.71 to +0.62 mm and −2.8 to +3.43 mm, respectively. Five DRT CBCT matches (8.33%) were outside the 3-mm threshold, all in the setting of bladder underfilling or rectal gas. The mean time for manual matching was 82 versus 65 s for DRT. XVI's DRT is comparable with RTs manually matching soft tissue on CBCT. The DRT can minimise RT inter-observer variability; however, involuntary bladder and rectal filling can influence the tools accuracy, highlighting the need for RT evaluation of the DRT match.

Para alcançarmos a resposta a tal questão, aprofundamos a visão de Joseph Ratzinger a partir de alguns de seus escritos teológicos (anteriores ao pontificado e, em seguida, nas suas três encíclicas, o ponto alto de seu magistério papal (Deus caritas est, Spe salvi e Caritas in veritate.

  1. Hibernation and gas exchange.

    Science.gov (United States)

    Milsom, William K; Jackson, Donald C

    2011-01-01

    Hibernation in endotherms and ectotherms is characterized by an energy-conserving metabolic depression due to low body temperatures and poorly understood temperature-independent mechanisms. Rates of gas exchange are correspondly reduced. In hibernating mammals, ventilation falls even more than metabolic rate leading to a relative respiratory acidosis that may contribute to metabolic depression. Breathing in some mammals becomes episodic and in some small mammals significant apneic gas exchange may occur by passive diffusion via airways or skin. In ectothermic vertebrates, extrapulmonary gas exchange predominates and in reptiles and amphibians hibernating underwater accounts for all gas exchange. In aerated water diffusive exchange permits amphibians and many species of turtles to remain fully aerobic, but hypoxic conditions can challenge many of these animals. Oxygen uptake into blood in both endotherms and ectotherms is enhanced by increased affinity of hemoglobin for O₂ at low temperature. Regulation of gas exchange in hibernating mammals is predominately linked to CO₂/pH, and in episodic breathers, control is principally directed at the duration of the apneic period. Control in submerged hibernating ectotherms is poorly understood, although skin-diffusing capacity may increase under hypoxic conditions. In aerated water blood pH of frogs and turtles either adheres to alphastat regulation (pH ∼8.0) or may even exhibit respiratory alkalosis. Arousal in hibernating mammals leads to restoration of euthermic temperature, metabolic rate, and gas exchange and occurs periodically even as ambient temperatures remain low, whereas body temperature, metabolic rate, and gas exchange of hibernating ectotherms are tightly linked to ambient temperature. © 2011 American Physiological Society.

    2001-01-01

    A radial flow heat exchanger (20) having a plurality of first passages (24) for transporting a first fluid (25) and a plurality of second passages (26) for transporting a second fluid (27). The first and second passages are arranged in stacked, alternating relationship, are separated from one another by relatively thin plates (30) and (32), and surround a central axis (22). The thickness of the first and second passages are selected so that the first and second fluids, respectively, are transported with laminar flow through the passages. To enhance thermal energy transfer between first and second passages, the latter are arranged so each first passage is in thermal communication with an associated second passage along substantially its entire length, and vice versa with respect to the second passages. The heat exchangers may be stacked to achieve a modular heat exchange assembly (300). Certain heat exchangers in the assembly may be designed slightly differently than other heat exchangers to address changes in fluid properties during transport through the heat exchanger, so as to enhance overall thermal effectiveness of the assembly.

Safety rod testing was being performed as part of the power ascension testing program. The results of cooling water samples indicated tritium concentrations higher than allowable. Further sampling and testing confirmed a Process Water System to Cooling Water System leak in heat exchanger 4A (HX 4A). The heat exchanger was isolated and the plant shutdown. Heat exchanger 4A was removed from the plant and moved to C-Area prior to performing examinations and diagnostic testing. This included locating and identifying the leaking tube or tubes, eddy current examination of the leaking tube and a number of adjacent tubes, visually inspecting the leaking tube from both the inside as well as the area surrounding the identified tube. The leaking tube was removed and examined metallurgically to determine the failure mechanism. In addition ten other tubes that either exhibited eddy current indications or would represent a baseline condition were removed from heat exchanger 4A for metallurgical examination. Additional analysis and review of heat exchanger leakage history was performed to determine if there are any patterns which can be used for predictive purposes.

It is deduced that the arguments used by the informers of the king on the intellectual deficiencies of its abbots, are an excuse to justify the true regal interests, that were not but those to remove to these centers of the obedience of the house French mother, from fear of the heretical influences that could arrive at the heat of a country that was living a religion war process. Finally the philippine plans will leave ahead using like blunt weapon the Right Patronage, although in s.

Con el presente trabajo comprobaremos que este tipo de fuentes contienen valiosos datos para la Historia en general pero ante todo para la Historia Económica. En el caso concreto que abordamos, nos han servido para conocer cómo, cuando y donde se realizaron reparos, remodelaciones y nuevas construcciones en la Alhambra del siglo XVI, tema de vital importancia para la Historia del Arte de este monumento. Las obras reales de la Alhambra fueron iniciadas en la etapa de los Reyes Católicos, al día siguiente de la entrada en el recinto, cuando comprobaron el deterioro de esta bella ciudadela y fortaleza. Con el mismo ahínco y respeto fueron seguidas por su nieto Carlos V, quien sumó, al antiguo conjunto palaciego, la construcción del palacio imperial y su entorno urbanístico renacentistas. Finalmente, las obras fueron continuadas por Felipe II y sus sucesores los Austrias. Gracias al esfuerzo económico realizado por ellos, sobre todo durante el siglo XVI, hoy podemos contemplar la Alhambra. Ratifican lo dicho los Cargos y Datas de los libros de cuentas de Ceprián y Gaspar, fedatarios del volumen de las inversiones y de los considerables gastos realizados por la Real Hacienda castellana en las obras de la Alhambra1.

En la arqueología el énfasis se ha limitado a analizar procesos prehispánicos adaptativos a condiciones cambiantes del medio ambiente dejando de manera tacita fuera de foco la discusión de las consecuencias sociales y culturales de la conquista y la colonia y su impacto en el tejido social que surgiría a finales del siglo XVI. Estas delimitaciones disciplinarias se han convertido en un obstáculo para el conocimiento e interpretación de las dinámicas que siguieron al impulso inicial de la colonización del litoral caribeño y la bien conocida fundación de los centros militares y administrativos. Consecuentemente los historiadores han ignorado en gran parte el papel de las poblaciones aborígenes en la formación de los asentamientos al interior de la llanura costera a pesar que es un hecho bien conocido que no desaparecieron completamente después del siglo XVI. A pesar de que han existido intentos de sintetizar y complementar la información histórica con datos arqueológicos especialmente en los últimos diez años no hemos asistido a un evaluación del campo que consideramos de la mayor importancia para entender la estrategias a traves de las cuales las comunidades aborígenes y algo mas tarde las comunidades de composición mixta africano-indígena y mestizas establecieron exitosamente una serie de asentamientos fuera del sistema colonial reinante. El análisis de los patrones de asentamiento se ha restringido a estudios arqueológicos pero su potencial se extiende mucho mas alla de esta disciplina. La colonia en el siglo XVIII registra un gran número de asentamientos en las planicies caribeñas para los cuales tenemos muy poca información precedente, se hace necesario entonces entender el sistema de asentamientos que exitosamente

    A heat exchanger having a plurality of heat exchanging aluminum fins with hydrophilic condensing surfaces which are stacked and clamped between two cold plates. The cold plates are aligned radially along a plane extending through the axis of a cylindrical duct and hold the stacked and clamped portions of the heat exchanging fins along the axis of the cylindrical duct. The fins extend outwardly from the clamped portions along approximately radial planes. The spacing between fins is symmetric about the cold plates, and are somewhat more closely spaced as the angle they make with the cold plates approaches 90.degree.. Passageways extend through the fins between vertex spaces which provide capillary storage and communicate with passageways formed in the stacked and clamped portions of the fins, which communicate with water drains connected to a pump externally to the duct. Water with no entrained air is drawn from the capillary spaces.

    The optimization of ion-exchange column design becomes increasingly important in applications where high efficiency is required to remove trace components in wastewater to very low discharge requirements and for treating hazardous wastewaters where the disposal costs for secondary waste is extremely high. A predictive mathematical model is being developed for improved design of ion-exchange columns for treatment of wastewaters which are contaminated with trace quantities of Sr-90 and Cs-137. Equilibria isotherms and mass transfer mechanisms are being experimentally determined for isothermal multicomponent ion exchange of Ca, Mg, Na, Ca, and Sr with Ionsive IE-95 chabazite zeolite. These equations are being included in a mathematical model to determine the cation breakthrough curves for different column configurations and operating conditions

  17. Sorption by cation exchange

    International Nuclear Information System (INIS)

    Bradbury, M.H.; Baeyens, B.

    1994-04-01

    A procedure for introducing exchange into geochemical/surface complexation codes is described. Beginning with selectivity coefficients, K c , defined in terms of equivalent fractional ion occupancies, a general expression for the molar based exchange code input parameters, K ex , is derived. In natural systems the uptake of nuclides onto complex sorbents often occurs by more than one mechanism. The incorporation of cation exchange and surface complexation into a geochemical code therefore enables sorption by both mechanisms to be calculated simultaneously. The code and model concepts are tested against sets of experimental data from widely different sorption studies. A proposal is made to set up a data base of selectivity coefficients. Such a data base would form part of a more general one consisting of sorption mechanism specific parameters to be used in conjunction with geochemical/sorption codes to model and predict sorption.

    1978-01-01

    A heat exchanger for use in nuclear reactors includes a heat exchange tube bundle formed from similar modules each having a hexagonal shroud containing a large number of thermally conductive tubes which are connected with inlet and outlet headers at opposite ends of each module, the respective headers being adapted for interconnection with suitable inlet and outlet manifold means. In order to adapt the heat exchanger for operation in a high temperature and high pressure environment and to provide access to all tube ports at opposite ends of the tube bundle, a spherical tube sheet is arranged in sealed relation across the chamber with an elongated duct extending outwardly therefrom to provide manifold means for interconnection with the opposite end of the tube bundle.

    Ion exchange phenomena involve the population of readily exchangeable ions, the subset of adsorbed solutes that balance the intrinsic surface charge and can be readily replaced by major background electrolyte ions (Sposito, 2008). These phenomena have occupied a central place in soil chemistry research since Way (1850) first showed that potassium uptake by soils resulted in the release of an equal quantity of moles of charge of calcium and magnesium. Ion exchange phenomena are now routinely modeled in studies of soil formation (White et al., 2005), soil reclamation (Kopittke et al., 2006), soil fertilitization (Agbenin and Yakubu, 2006), colloidal dispersion/flocculation (Charlet and Tournassat, 2005), the mechanics of argillaceous media (Gajo and Loret, 2007), aquitard pore water chemistry (Tournassat et al., 2008), and groundwater (Timms and Hendry, 2007; McNab et al., 2009) and contaminant hydrology (Chatterjee et al., 2008; van Oploo et al., 2008; Serrano et al., 2009).

    After expansion of the vector and axial vector currents in powers of (v/c), a heretofore unremarked regularity results. Meson exchange currents can be classified into types I and II, according to the way they satisfy the constraints of special relativity. The archetypes of these two categories are the impulse approximation to the vector and axial vector currents. After a brief discussion of these constraints, the (rhoπγ) and (ωsigmaγ) exchange currents are constructed and classified, and used to illustrate a number of important points which are often overlooked

    Most geothermal fluids, because of their elevated temperature, contain a variety of dissolved chemicals. These chemicals are frequently corrosive toward standard materials of construction. As a result, it is advisable in most cases to isolate the geothermal fluid from the process to which heat is being transferred. The task of heat transfer from the geothermal fluid to a closed process loop is most often handled by a plate heat exchanger. The two most common types used in geothermal applications are: bolted and brazed. For smaller systems, in geothermal resource areas of a specific character, downhole heat exchangers (DHEs) provide a unique means of heat extraction. These devices eliminate the requirement for physical removal of fluid from the well. For this reason, DHE-based systems avoid entirely the environmental and practical problems associated with fluid disposal. Shell and tube heat exchangers play only a minor role in low-temperature, direct-use systems. These units have been in common use in industrial applications for many years and, as a result, are well understood. For these reasons, shell and tube heat exchangers will not be covered in this chapter.

    The claimed heat exchanger is characteristic by the condensate level being maintained directly in the exchanger while preserving the so-called ''dry'' tube plate. This makes it unnecessary to build another pressure vessel into the circuit. The design of the heat exchanger allows access to both tube plates, which facilitates any repair. Another advantage is the possibility of accelerating the indication of leakage from the space of the second operating medium which is given by opening the drainage pipes of the lower bundle into the collar space and from there through to the indication pipe. The exchanger is especially suitable for deployment in the circuits of nuclear power plants where the second operating medium will be hot water of considerably lower purity than is that of the condensate. A rapid display of leakage can prevent any long-term penetration of this water into the condensate, which would result in worsening water quality in the entire secondary circuit of the nuclear power plant.

    Purpose: To improve the stability and the operationability of the fuel exchanging work by checking the validity of the data before the initiation of the work. Constitution: A floppy disc stores the initial charging state data showing the arrangement of fuel assemblies in the reactor core pool, data showing the working procedures for the fuel exchange and a final charged state data upon completion of the work. The initial data and the procedure data are read from the disk and stored once into a memory. Then, the initial data are sequentially performed on the memory in accordance with the procedure data and, thereafter, they were compared with the final data read from the disk. After confirming that there are no errors in the working data, the procedure data are orderly instructed to the fuel exchanger for performing fuel replacement. Accordingly, since the data are checked before the initiation of the work, the fuel exchange can be performed automatically thereby improving the operationability thereof. (Yoshino, Y.)

This article analyzes such organizations as key nodes of colonial society, through a symbiotic relationship with the colonial elite, which continued until the dawn of republican era. This link were favored by institutions such as chaplaincies and pious deeds. It allowed, among other things, the provision of many of the new members of the order and endowed convents of movable and immovable property and capital necessary for its functioning, in exchange for ensuring social order and provide prestige for this life and salvation for the other. This successful model was torn apart with the advent of the Enlightenment and will fall precipitously shortly after Independence.

O primeiro era a língua "geral" (nheengatu, falada por todos e de aprendizado obrigatório para os jesuítas; o segundo estava restrito às casas de bê-á-bá mantidas pela Companhia de Jesus. Neste contexto surgiu o teatro anchietano, encenado preferencialmente em português e tupi, com o objetivo de catequizar. Nosso estudo nos permitiu concluir que, tanto na forma como no conteúdo, o teatro serviu à aculturação, pois "cristianizou" a cultura indígena ridicularizando os seus mitos, que eram protagonizados pelos próprios índios, além de expandir o uso do português, principal idioma das peças. Começou aí a substituição da pluralidade lingüística pelo português, hegemônico a partir do século XVIII.

  4. Counterflow Regolith Heat Exchanger

    A problem exists in reducing the total heating power required to extract oxygen from lunar regolith. All such processes require heating a great deal of soil, and the heat energy is wasted if it cannot be recycled from processed material back into new material. The counterflow regolith heat exchanger (CoRHE) is a device that transfers heat from hot regolith to cold regolith. The CoRHE is essentially a tube-in-tube heat exchanger with internal and external augers attached to the inner rotating tube to move the regolith. Hot regolith in the outer tube is moved in one direction by a right-hand - ed auger, and the cool regolith in the inner tube is moved in the opposite direction by a left-handed auger attached to the inside of the rotating tube. In this counterflow arrangement, a large fraction of the heat from the expended regolith is transferred to the new regolith. The spent regolith leaves the heat exchanger close to the temperature of the cold new regolith, and the new regolith is pre-heated close to the initial temperature of the spent regolith. Using the CoRHE can reduce the heating requirement of a lunar ISRU system by 80%, reducing the total power consumption by a factor of two. The unique feature of this system is that it allows for counterflow heat exchange to occur between solids, instead of liquids or gases, as is commonly done. In addition, in variants of this concept, the hydrogen reduction can be made to occur within the counterflow heat exchanger itself, enabling a simplified lunar ISRU (in situ resource utilization) system with excellent energy economy and continuous nonbatch mode operation.

  7. The Metaphysics of Economic Exchanges

    Full Text Available What are economic exchanges? The received view has it that exchanges are mutual transfers of goods motivated by inverse valuations thereof. As a corollary, the standard approach treats exchanges of services as a subspecies of exchanges of goods. We raise two objections against this standard approach. First, it is incomplete, as it fails to take into account, among other things, the offers and acceptances that lie at the core of even the simplest cases of exchanges. Second, it ultimately fails to generalize to exchanges of services, in which neither inverse preferences nor mutual transfers hold true. We propose an alternative definition of exchanges, which treats exchanges of goods as a special case of exchanges of services and which builds in offers and acceptances. According to this theory: (i The valuations motivating exchanges are propositional and convergent rather than objectual and inverse; (ii All exchanges of goods involve exchanges of services/actions, but not the reverse; (iii Offers and acceptances, together with the contractual obligations and claims they bring about, lie at the heart of all cases of exchange.

    Compact heat exchangers are subject to different constraints as a room temperature gas is cooled down by a cold stream returning from a JT valve (or a similar cryoprocess component). In particular, the optimization of exchangers for liquid helium systems has to cover a wide range in temperature and density of the fluid. In the present work we address the following thermodynamic questions: 1. The optimization of intermediate temperatures which optimize stage operation (a stage is assumed to have a constant cross section); 2. The optimum temperature difference available for best overall economic performance values. The results are viewed in the context of porous media concepts applied to rather low speeds of fluid flow in narrow passages. In this paper examples of fluid/solid constraints imposed in this non-classical low temperature area are presented

    Lipids play an important role in maintaining P-type ATPase structure and function, and often they are crucial for ATPase activity. When the P-type ATPases are in the membrane, they are surrounded by a mix of different lipids species with varying aliphatic chain lengths and saturation......, and the complex interplay between the lipids and the P-type ATPases are still not well understood. We here describe a robust method to exchange the majority of the lipids surrounding the ATPase after solubilisation and/or purification with a target lipid of interest. The method is based on an ultracentrifugation...... step, where the protein sample is spun through a dense buffer containing large excess of the target lipid, which results in an approximately 80-85 % lipid exchange. The method is a very gently technique that maintains protein folding during the process, hence allowing further characterization...

    This study examined the rebounds in the exchange rate after foreign exchange intervention. When intervention is strongly effective, the exchange rate rebounds at next day. The effect of intervention is reduced slightly by the rebound after the intervention. The exchange rate might have been 67.12-77.47 yen to a US dollar without yen-selling/dollar-purchasing intervention of 74,691,100 million yen implemented by the Japanese government since 1991, in comparison to the actual exchange rate was 103.19 yen to the US dollar at the end of March 2014.

  13. The exchangeability of shape

    2010-10-01

    Full Text Available Abstract Background Landmark based geometric morphometrics (GM allows the quantitative comparison of organismal shapes. When applied to systematics, it is able to score shape changes which often are undetectable by traditional morphological studies and even by classical morphometric approaches. It has thus become a fast and low cost candidate to identify cryptic species. Due to inherent mathematical properties, shape variables derived from one set of coordinates cannot be compared with shape variables derived from another set. Raw coordinates which produce these shape variables could be used for data exchange, however they contain measurement error. The latter may represent a significant obstacle when the objective is to distinguish very similar species. Results We show here that a single user derived dataset produces much less classification error than a multiple one. The question then becomes how to circumvent the lack of exchangeability of shape variables while preserving a single user dataset. A solution to this question could lead to the creation of a relatively fast and inexpensive systematic tool adapted for the recognition of cryptic species. Conclusions To preserve both exchangeability of shape and a single user derived dataset, our suggestion is to create a free access bank of reference images from which one can produce raw coordinates and use them for comparison with external specimens. Thus, we propose an alternative geometric descriptive system that separates 2-D data gathering and analyzes.

  14. Scraped surface heat exchangers.

    Rao, Chetan S; Hartel, Richard W

    2006-01-01

    Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. They are ideally suited for products that are viscous, sticky, that contain particulate matter, or that need some degree of crystallization. Since these characteristics describe a vast majority of processed foods, SSHEs are especially suited for pumpable food products. During operation, the product is brought in contact with a heat transfer surface that is rapidly and continuously scraped, thereby exposing the surface to the passage of untreated product. In addition to maintaining high and uniform heat exchange, the scraper blades also provide simultaneous mixing and agitation. Heat exchange for sticky and viscous foods such as heavy salad dressings, margarine, chocolate, peanut butter, fondant, ice cream, and shortenings is possible only by using SSHEs. High heat transfer coefficients are achieved because the boundary layer is continuously replaced by fresh material. Moreover, the product is in contact with the heating surface for only a few seconds and high temperature gradients can be used without the danger of causing undesirable reactions. SSHEs are versatile in the use of heat transfer medium and the various unit operations that can be carried out simultaneously. This article critically reviews the current understanding of the operations and applications of SSHEs.

  15. Hydrogen isotope exchange reactions

    Jones, J.R.

    1980-01-01

    The two most widely used methods for following hydrogen isotope exchange reactions, namely dedeuteriation and detritiation, involve in the first place the synthesis of an appropriately labelled compound. Rates of dedeuteriation are usually followed by measuring changes in the 1 H n.m.r. spectrum of the substrate (examples are given); the method not only gives the rate but also the site(s) of exchange. It is limited to rather slow reactions and is not as accurate as some of the other methods. The development of deuterium n.m.r. spectroscopy means that changes in the 2 H n.m.r. spectrum can also be used to measure rates of dedeuteriation. The development of liquid scintillation counting greatly eased the problem of how to detect weak β emitters; the attractions of tritium as a tracer were thereby much enhanced. Nowadays the study of rates of detritiation constitutes one of the most versatile and accurate methods of following hydrogen isotope exchange. Examples of the technique are given. (U.K.)

  16. Paste heat exchange

    Energy Technology Data Exchange (ETDEWEB)

    1943-07-30

    The subject of coal paste heat exchangers is discussed in this letter report from Gelsenberg A.G. to I.G. Farbenindustrie A.G. Gelsenberg had given little consideration to the heating of coal paste by means of regeneration (heat exchange) because of the lack of experience in paste regeneration with bituminous coal, especially at 700 atmospheres. At the I.G. Farben plant at Poelitz, paste regeneration was carried out so that low concentration coal paste was heated in the regenerator together with the process gas, and the remaining coal was fed into the cold pass of the preheater in a thicker paste. Later tests proved this process viable. Gelsenberg heated normal coal paste and the gas in heat exchangers with the goal of relieving the preheater. Good results were achieved without change in design. The coal paste was heated with process gas in the regenerator at up to 315 degrees with constant pressure difference, so that after three months no decrease in K-values and no deposition or thickening was observed. Through the omission of paste gas, the pressure difference of the system became more constant and did not rise above the former level. The temperature also was more controllable, the chamber smoother running. Principal thermal data are given in a table. 1 table, 1 graph.

  17. Timing Foreign Exchange Markets

    2016-03-01

    Full Text Available To improve short-horizon exchange rate forecasts, we employ foreign exchange market risk factors as fundamentals, and Bayesian treed Gaussian process (BTGP models to handle non-linear, time-varying relationships between these fundamentals and exchange rates. Forecasts from the BTGP model conditional on the carry and dollar factors dominate random walk forecasts on accuracy and economic criteria in the Meese-Rogoff setting. Superior market timing ability for large moves, more than directional accuracy, drives the BTGP’s success. We explain how, through a model averaging Monte Carlo scheme, the BTGP is able to simultaneously exploit smoothness and rough breaks in between-variable dynamics. Either feature in isolation is unable to consistently outperform benchmarks throughout the full span of time in our forecasting exercises. Trading strategies based on ex ante BTGP forecasts deliver the highest out-of-sample risk-adjusted returns for the median currency, as well as for both predictable, traded risk factors.

    Review is made on the extraction with anion exchangers and the extraction with liquid cation exchangers. On the former, explanation is made on the extraction of acids, the relation between anion exchange and the extraction of metals, the composition of the metallic complexes that are extracted, and the application of the extraction with anion exchangers to analytical chemistry. On the latter, explanation is made on the extraction of metals and its application to analytical chemistry. The extraction with liquid ion exchangers is suitable for the operation in chromatography, because the distribution of extracting agents into aqueous phase is small, and extraction equilibrium is quickly reached, usually within 1 to several minutes. The separation by means of anion exchangers is usually made from hydrochloric acid solution. For example, Brinkman et al. determined Rf values for more than 50 elements by thin layer chromatography. Tables are given for showing the structure of the liquid ion exchangers and the polymerized state of various amines. (Mori, K.)

    2017-03-01

    Full Text Available Este trabalho pretende analisar as relações existentes entre o discurso atual sobre a emancipação através da Educação, enunciado pelas propostas educacionais ditas inovadoras, e as obras publicadas no século XVI, como Utopia, de Thomas More, onde a emancipação estava condicionada a uma transformação social profunda. A emancipação, como categoria, foi abordada por Marx em suas obras de juventude, ora como categoria de análise da emancipação religiosa (A Questão Judaica, ora como categoria condicionada pela alienação (Manuscritos Econômico-Filosóficos. Uma Utopia, em determinado momento histórico, aparece como discurso de fronteiras sempre móveis, sempre alguns passos à frente da realidade objetiva. Ela também se constitui como obra crítica ao existente em sua época. A partir desta constatação, propõe-se a análise do discurso emancipatório presente nas propostas educacionais ditas ―inovadoras‖ na atualidade, que atribuem ao poder presente na individualidade, na subjetividade e no protagonismo do aluno a emancipação do homem, desprezando ou desconsiderando a complexidade do contexto histórico social mais amplo. Com esta proposta, pretende-se discutir limites e potencialidades das propostas educacionais ditas ―inovadoras‖.

    Full Text Available Using epigraphic testimonies and unpublished documents, we can establish that the chapel of the family Neira de Luaces was founded in the first quarter of the 16th Century, being sponsored by Juan Outeiro, ancient alderman of Santiago de Compostela. This chapel is in the church of Santa María do Camiño, a building directly linked with the pilgrimages tradition, situated near of the old door of the French Way. We try to describe the historical evolution of this chapel till today, making a bibliographical review and a historiographical synthesis, where are combined material evidences and textual testimonies. We are also publishing new information about its artistic configuration that acquires a new dimension and a new meaning, being understood in the context of the family pantheon.

    A partir de noticias epigráficas y documentales inéditas se puede establecer la fundación de la capilla de los Neira de Luces en la primera mitad del siglo XVI, bajo el patrocinio de Juan Outeiro regidor de la ciudad de Santiago. La capilla se encuentra en la iglesia compostelana de Santa María do Camiño, muy ligada a la tradición jacobea por estar situada en la entrada de la ciudad, junto a la antigua puerta del Camino Francés. Se sigue en lo posible su evolución hasta nuestros días, efectuando una labor de revisión y síntesis históriográfica que combina la evidencia material y la escrita. Se aportan además, algunos datos sobre determinados aspectos artísticos que adquieren nueva dimensión y significado al ser tratados en su conjunto, contextualizando el recinto funerario familiar en el ámbito urbano y considerando al mismo tiempo los diferentes períodos históricos.

    Cañeque, Alejandro

    2004-12-01

    Full Text Available This article examines the relationship between public ritual and colonial authority in sixteenth and seventeenth-century New Spain. In colonial society, the establishment of authority depended more on such things as prestige, reputation and/or public appearance than on the use of force. This helps explain the great transcendence attributed by contemporaries to all kinds of public rituals. Their effects were far from negligible: they were much more than a disguise with which to make the rulers’ power more palatable. Royal officials constituted their power and identities through public ceremony, and therefore placed crucial importance on maintaining an authoritative public image.

    El artículo estudia la interrelación entre ritual público y autoridad colonial en la Nueva España de los siglos XVI y XVII. En la sociedad colonial, el afianzamiento de la autoridad dependía más de cuestiones tales como prestigio, reputación y/o apariencia pública que del uso de la fuerza. Eso permite explicar la trascendencia tan grande que los contemporáneos dieron a todo tipo de rituales públicos pues sus efectos estaban lejos de ser algo insignificante y eran mucho más que simples disfraces para hacer más digerible el poder de los gobernantes. Los oficiales reales consituían su poder y su identidad a través del ceremonial público y, por tanto, daban una importancia crucial al mantenimiento de una imagen pública llena de autoridad.

    A major debate is currently underway in the USA about whether there is, in fact, a science, technology, engineering and mathematics (STEM) workforce shortage in the country or not. This is the subject of the Bayer Facts of Science Education XVI: US STEM Workforce Shortage—Myth or Reality? Fortune 1000 Talent Recruiters on the Debate. An ongoing public opinion research project commissioned by Bayer Corporation, the Bayer Facts surveys examine US STEM education, diversity and workforce issues. The 16th in the series, the newest survey asks talent recruiters at some of the country's largest employers—those included in the Fortune 1000—to weigh in on current and future demand for new hires with 2- and 4-year STEM degrees. As professionals responsible for scouting, recruiting and hiring talent at Fortune 1000 companies, both STEM and non-STEM alike, these individuals are on the frontlines, tasked with assessing and filling their companies' workforce needs. The survey asks the recruiters whether new hires with 2- and 4-year STEM degrees are as, more or less in demand than their peers without STEM degrees? Are more new STEM jobs being created at their companies than non-STEM jobs? Can they find adequate numbers of qualified candidates in a timely manner and how fierce is the competition for STEM degree holders? To answer these and other questions, the survey polled 150 talent recruiters at Fortune 1000 companies, both STEM and non-STEM alike. The survey also asks the recruiters about diversion in STEM, workforce diversity in the pipeline, the role of community colleges in developing the STEM pipeline and the desired skills and competencies of new hires.

    Full Text Available O artigo analisa as primeiras impressões que cronistas leigos e missionários formularam sobre as expressões de sensibilidade e de religiosidade dos indígenas Tupi-guarani, em especial, daquelas relacionadas ao festejar e aos lamentos fúnebres. Nas crônicas e correspondências quinhentistas e seiscentistas, são recorrentes as referências a comportamentos tidos como bárbaros, especialmente diante dos doentes e mortos, e a associação de cantos, bailes e bebedeiras à violência, desregramento, antropofagia e superstições, apontando para a incapacidade dos ocidentais de compreenderem o profundo simbolismo que envolvia estas práticas e rituais nativas. Apresentadas como demonstrações emocionais excessivamente espontâneas, em flagrante desacordo com as condutas tidas como civilizadas, que previam o autocontrole das paixões e dos impulsos afetivos e a observância da moral tridentina, as manifestações de sensibilidade e religiosidade indígena ocuparam a atenção de cronistas leigos e missionários empenhados na sua civilização e conversão. Ao longo do século XVI e dos seguintes, expressões próprias da sensibilidade e da religiosidade indígena serão apresentadas, sobretudo na documentação jesuítica, como indícios do êxito de sua conversão ao cristianismo, sem que, no entanto, qualquer menção ou importância fosse atribuída às negociações e às apropriações feitas pelos missionários e pelos próprios nativos da América portuguesa.

    This article analyses exchanges of support between the elderly and adult generations and by gender, based on data from the United Nations household survey in Mexico City (SABE, 2000), and the National Study of Ageing and Health (ENASEM, 2001). Results indicate that in Mexico both generations – elderly parents and adult children – provide support, such as money, services, care or gifts for grandchildren, according to gender roles and the generation’s resources. Men provide monetary support and reproduce their role as family providers, but this role depends on having an income from work and, in later years, a pension, a more common situation among men than among women. Women develop their female domestic role as caregivers. They do not have a formal income, but receive informal economic support and offer services and care to their relatives, reproducing their invisible and unpaid work during their life course. Both types of support are widely exchanged between elderly parents and adult children and children-in-law. PMID:29375143

    commercial education. An apprentice could not trade for his own without his merchant's permission who, to certain extent, was responsible for the apprentices' actions. The knowledge an agent had about a foreign market used to have an influence on the merchant's decision about which goods should be exported. Factors, apart from writing letters, should keep books of accounts, which implied a knowledge of bookkeeping, foreign currencies and bills of exchange. Foreign trade conditions increased factors' responsibilities and created new representation problems which have no equivalence in other commercial relations of the period.

    The neutron activation analysis (NAA) of three samples of human remains of the XVI-XVII centuries from the necropolises of the Moscow Kremlin has been carried out at FLNP JINR. The samples were irradiated at two facilities: at the IREN source of resonance neutrons and at the IBR-2 reactor. Spectra of induced activity of the irradiated samples were measured by using the automatic measurement system developed at FLNP JINR. This system consists of a high-purity germanium detector with spectrometric electronics, a sample changer, and a control software. Mass fractions of arsenic, mercury and other elements were calculated by relative and absolute NAA methods. The obtained values confirmed the fact of an acute mercury poisoning of the first wife of Tsar Ivan Vasilievich the Terrible - Tsarina Anastasia Romanovna. Increased mercury content was detected in the bone remains of the son of Tsar Ivan the Terrible, Tsarevich Ivan Ivanovich, and Prince M. V. Skopin-Shuisky. The obtained results allow us to introduce into scientific circulation the exact values of mass fraction of mercury, arsenic and some other elements in the samples from the graves of Russian historical figures of the second half of XVI - early XVII centuries.

    A hybrid light-weight heat exchanger concept has been developed that uses high-conductivity carbon-carbon (C-C) composites as the heat-transfer fins and uses conventional high-temperature metals, such as Inconel, nickel, and titanium as the parting sheets to meet leakage and structural requirements. In order to maximize thermal conductivity, the majority of carbon fiber is aligned in the fin direction resulting in 300 W/m.K or higher conductivity in the fin directions. As a result of this fiber orientation, the coefficient of thermal expansion (CTE) of the C-C composite in both non-fiber directions matches well with the CTE of various high-temperature metal alloys. This allows the joining of fins and parting sheets by using high-temperature braze alloys.

    The Radioecology Exchange (www.radioecology-exchange.org) was created in 2011 under the EU FP7 STAR (Strategy for Allied Radioecology) network of excellence. The project aims to integrate the research efforts on radioecology of nine European organisations into a sustainable network. The web site (together with associated Twitter feeds and Facebook page) currently provides the gateway to project outputs and other on-line radiation protection and radioecological resources. In 2013, the EU FP7 COMET (Coordination and implementation of a pan-European instrument for radioecology) project commenced; it aims to strengthen research on the impact of radiation on man and the environment. COMET includes the STAR partners with the addition of one Japanese and two Ukrainian research institutes. As STAR and COMET interact closely together and with the European Radioecology Alliance (www.er-alliance.org/), the Radioecology Exchange will be modified to become an international 'hub' for information related to radioecology. Project specific information will be hosted on separate web sites www.star-radioecology.org and www.comet-radioecology.org. This paper will present an overview of the resources hosted on the Radioecology Exchange inviting other scientists to contribute. Highlighted aspects of the site include: Social media (News blog, Twitter, Facebook) - Items announcing project outputs, training courses, jobs, studentships etc. Virtual laboratory - Information which encourages integration through joint research and integrated use of data and sample materials. These pages will focus on three categories: (1) Methodological: descriptions and video clips of commonly used analytical methods and protocols and the procedures used in STAR and COMET; (2) Informative: databases made available by STAR/COMET partners together with details of sample archives held. Fact-sheets on radio-ecologically important radionuclides and 'topical descriptions' which show absorbed

    Full Text Available Cuando se hace mención del impacto de la llegada de los españoles sobre los pueblos indígenas, se suele hablar casi siempre de aspectos tangibles y cuantificables: descenso demográfico, cambio de habitats, migraciones, nuevo sistema económico, dominación política, cambio de estructura social, etc.; sin embargo, hay otra serie de aspectos más difíciles de aprehender este fenómeno de aculturación, absorción cultural o «desestructuración». Nos referimos a los denominados de una forma excesivamente genérica como objeto de estudio por parte de la «Historia Espiritual» o «Historia de las Mentalidades», por utilizar el término actualmente más reiterado en la bibliografía reciente. Dentro de este «etéreo» apartado de la Historia, la Conciencia como capacidad de distinción entre el Bien y el Mal con toda su complejidad a lo largo del tiempo, debería ocupar un lugar por sí misma; no estaría de más que en estos momentos en que todo se considera digno de ser considerado como objeto de grandes historias —desde el calzado a la vida privada—, se publicase una «Historia de la Conciencia». El objetivo de este artículo es mucho más modesto, sólo pretende ayudar a entender la formación de la Conciencia cristiana de los indígenas y su proceso, a través de los «manuales de confesión» del siglo XVI; sin embargo, hay otros muchos temas anejos a éste y presentes en los «manuales» que estudiamos; temas que no vamos a desarrollar del todo, pero que ofrecemos a modo de sugerencia para otros especialista y futuros trabajos.

    Full Text Available La historia de la alfabetización se ha convertido en un campo interdisciplinario en el que han confluido en los últimos años historiadores generales, los específicamente interesados en el campo de la cultura, educación o literatura, los preocupados por cuestiones económico-profesionales, los historiadores de la familia y los antropólogos. Desde que Bartolomé Bennassar y Marie-Christine Rodríguez presentaran sus trabajos sobre el grado de instrucción popular en Córdoba y Toledo, han sido numerosos los estudios de esta índole centrados sobre las zonas geográficas más diversas. Para llevarlos a cabo, los distintos autores se han servido de fuentes notariales, inquisitoriales, fiscales, etc. Pero lo que ha atraído nuestra atención sobre el tema ha sido la documentación conservada en el Archivo General de Simancas y en la Biblioteca de El Escorial, relativa a un proyecto frustrado de ordenación de la enseñanza de las primeras letras en el Madrid del siglo XVI. Los materiales conservados en El Escorial eran conocidos y habían sido aprovechados convenientemente por R. Kagan para redactar sus páginas dedicadas a la enseñanza de las primeras letras. Sin embargo, los albergados en Simancas se hallan inéditos. Su ubicación en una de las secciones económicas del archivo puede justificar el olvido de que han sido objeto hasta el presente. Originariamente, tanto la documentación de Simancas como la de El Escorial, constituyó una unidad documental, que por razones desconocidas se rompió en un momento dado. El conjunto de todos los papeles pertenece a unas consultas del Consejo en el año 1587 sobre la regulación del acceso al ejercicio de la enseñanza de las primeras letras. Fruto de estos trámites administrativos surgió una minuta de documento real que no llegó a alcanzar cuerpo legal definitivo, pese a lo cual constituye una buena expresión de las ideas de Felipe II en materia de enseñanza primaria.

    Full Text Available Given the limited scientific training of pilots who traveled to the Spanish Indies in the early sixteenth century, Spanish Crown, first with Charles V and later with Philip II, was devoted not only to build institutions and scientific positions for organizing the nautical and cosmographic knowledge of the New World, but also teaching methods designed in the form of lectures, courses and examinations for the training and licensing of those navigators willing to sail the Mar Océano (Atlantic Ocean. The ultimate objective of the Monarchy was, first, to guarantee the maintenance of its production overseas Empire and, secondly, to ensure both the safety of their fleets and their men as well as State coffers, since the shipwrecks posed serious economic losses.

    Dada la escasa formación científica de los pilotos que viajaban a Indias en los primeros años del siglo XVI, la Corona española, primero con Carlos I al frente y más tarde con Felipe II, no sólo se conformó con crear instituciones y cargos científicos para organizar el saber náutico y cosmográfico del Nuevo Mundo, sino que además diseñó métodos pedagógicos, en forma de cátedras, cursos y exámenes, para la formación y licencia de aquellos navegantes dispuestos a surcar el “Mar Océano”. El objetivo último de la Monarquía era, por un lado, garantizar el mantenimiento de su productivo imperio de ultramar y, por el otro, velar tanto por la seguridad de sus flotas y hombres como por las arcas del Estado, pues los naufragios de los navíos suponían grandes pérdidas económicas. La unión entre ciencia y experiencia sería el mejor remedio.

    When the reduction of the construction cost of FBRs is considered from the standpoint of the machinery and equipment, to make the size small and to heighten the efficiency are the assigned mission. In order to make a reactor vessel small, it is indispensable to decrease the size of the equipment for fuel exchange installed on the upper part of a core. Mitsubishi Heavy Industries Ltd. carried out the research on the development of a new type fuel exchange system. As for the fuel exchange system for FBRs, it is necessary to change the mode of fuel exchange from that of LWRs, such as handling in the presence of chemically active sodium and inert argon atmosphere covering it and handling under heavy shielding against high radiation. The fuel exchange system for FBRs is composed of a fuel exchanger which inserts, pulls out and transfers fuel and rotary plugs. The mechanism adopted for the new type fuel exchange system that Mitsubishi is developing is explained. The feasibility of the mechanism on the upper part of a core was investigated by water flow test, vibration test and buckling test. The design of the mechanism on the upper part of the core of a demonstration FBR was examined, and the new type fuel exchange system was sufficiently applicable. (Kako, I.)

    In Next Generation Microchannel Heat Exchangers, the authors’ focus on the new generation highly efficient heat exchangers and presentation of novel data and technical expertise not available in the open literature.  Next generation micro channels offer record high heat transfer coefficients with pressure drops much less than conventional micro channel heat exchangers. These inherent features promise fast penetration into many mew markets, including high heat flux cooling of electronics, waste heat recovery and energy efficiency enhancement applications, alternative energy systems, as well as applications in mass exchangers and chemical reactor systems. The combination of up to the minute research findings and technical know-how make this book very timely as the search for high performance heat and mass exchangers that can cut costs in materials consumption intensifies.

  15. Heat exchanger leakage problem location

    2012-04-01

    Full Text Available Recent compact heat exchangers are very often assembled from numerous parts joined together to separate heat transfer fluids and to form the required heat exchanger arrangement. Therefore, the leak tightness is very important property of the compact heat exchangers. Although, the compact heat exchangers have been produced for many years, there are still technological problems associated with manufacturing of the ideal connection between the individual parts, mainly encountered with special purpose heat exchangers, e.g. gas turbine recuperators. This paper describes a procedure used to identify the leakage location inside the prime surface gas turbine recuperator. For this purpose, an analytical model of the leaky gas turbine recuperator was created to assess its performance. The results obtained are compared with the experimental data which were acquired during the recuperator thermal performance analysis. The differences between these two data sets are used to indicate possible leakage areas.

  17. Fault-Tolerant Heat Exchanger

    Science.gov (United States)

    Izenson, Michael G.; Crowley, Christopher J.

    2005-01-01

    A compact, lightweight heat exchanger has been designed to be fault-tolerant in the sense that a single-point leak would not cause mixing of heat-transfer fluids. This particular heat exchanger is intended to be part of the temperature-regulation system for habitable modules of the International Space Station and to function with water and ammonia as the heat-transfer fluids. The basic fault-tolerant design is adaptable to other heat-transfer fluids and heat exchangers for applications in which mixing of heat-transfer fluids would pose toxic, explosive, or other hazards: Examples could include fuel/air heat exchangers for thermal management on aircraft, process heat exchangers in the cryogenic industry, and heat exchangers used in chemical processing. The reason this heat exchanger can tolerate a single-point leak is that the heat-transfer fluids are everywhere separated by a vented volume and at least two seals. The combination of fault tolerance, compactness, and light weight is implemented in a unique heat-exchanger core configuration: Each fluid passage is entirely surrounded by a vented region bridged by solid structures through which heat is conducted between the fluids. Precise, proprietary fabrication techniques make it possible to manufacture the vented regions and heat-conducting structures with very small dimensions to obtain a very large coefficient of heat transfer between the two fluids. A large heat-transfer coefficient favors compact design by making it possible to use a relatively small core for a given heat-transfer rate. Calculations and experiments have shown that in most respects, the fault-tolerant heat exchanger can be expected to equal or exceed the performance of the non-fault-tolerant heat exchanger that it is intended to supplant (see table). The only significant disadvantages are a slight weight penalty and a small decrease in the mass-specific heat transfer.

    The purpose of the study was to determine what energy savings can be achieved by coordinating the resources and requirements of two facilities, the 26th Ward Water Pollution Control Plant (WPCP) and a housing development named Starrett City with its own total energy system. It was determined that three energy exchange options were economically and technically feasible. These include: the transfer of digester gas produced at the 26th Ward to the boilers at the Starrett City's total energy plant (TEP); the transfer of hot water heated at the TEP to the 26th Ward for space and process heating; and the transfer of coal effluent waste water from the 26th Ward to the condenser cooling systems at the TEP. Technical information is presented to support the findings. The report addresses those tasks of the statement of work dedicated to data acquisition, analysis, and energy conservation strategies internal to the Starrett City TEP and the community it supplies as well as to the 26th Ward WPCP.

    2017-12-01

    Full Text Available Nel 1546 si pubblica a Siviglia una traduzione “non autorizzata” dell’episodio delle «Tredici Questioni d’amore» che fanno parte del IV libro del Filocolo di Boccaccio. Lo stesso anno, a Toledo, si pubblica la traduzione dello stesso testo, questa volta con il permesso dei traduttori. Di quest’ultima si faranno due riedizioni, la prima a Toledo nel 1549 e la seconda a Venezia nel 1553. La traduzione è opera di due traduttori: Diego López de Ayala, canonico della cattedrale di Toledo, che si occupa della traduzione del testo, e Diego de Salazar, che compone dei poemetti che servono come riassunto sia dell’argo- mento di ognuna delle questioni sia della soluzione finale. Entrambi i traduttori collaboreranno nuovamente nella traduzione dell’Arcadia di Sannazaro. Da ricerche precedenti si può stabilire come testo base della traduzione l’incunabolo veneto del Filocolo del 1472 (riedito nel 1481, 1488 e 1497. L’articolo confronta contrastivamente i due testi per individuare, in un primo momento, le differenti tecniche e strategie traduttologiche usate da López de Ayala. Scopo dello studio non è solo quello di descrivere queste tecniche, ma anche di metterle in rapporto con vari aspetti che riguardano la cultura editoriale e la situazione sociale della Spagna del XVI secolo, come il nuovo tipo di lettori, la censura letteraria – ragione per la quale, a nostro avviso, il traduttore modifica e manipola frammenti del testo – o la finalità ultima del testo che vede modificata la sua funzione testuale rispetto al testo d’origine. In effetti, la traduzione spagnola si avvicina piú a una specie di catalogo di casistica amorosa con intenzionalità didattica e moraleggiante, diversa dalla funzione di diletto del romanzo sentimentale di derivazione alessandrina scritto da Boccaccio. Prima di affrontare l’analisi della traduzione si offre un’introduzione in cui vengono contestualizzate la storia editoriale della Spagna del

  1. Custom, contract, and kidney exchange.

    Science.gov (United States)

    Healy, Kieran; Krawiec, Kimberly D

    2012-01-01

    In this Essay, we examine a case in which the organizational and logistical demands of a novel form of organ exchange (the nonsimultaneous, extended, altruistic donor (NEAD) chain) do not map cleanly onto standard cultural schemas for either market or gift exchange, resulting in sociological ambiguity and legal uncertainty. In some ways, a NEAD chain resembles a form of generalized exchange, an ancient and widespread instance of the norm of reciprocity that can be thought of simply as the obligation to “pay it forward” rather than the obligation to reciprocate directly with the original giver. At the same time, a NEAD chain resembles a string of promises and commitments to deliver something in exchange for some valuable consideration--that is, a series of contracts. Neither of these salient "social imaginaries" of exchange--gift giving or formal contract--perfectly meets the practical demands of the NEAD system. As a result, neither contract nor generalized exchange drives the practice of NEAD chains. Rather, the majority of actual exchanges still resemble a simpler form of exchange: direct, simultaneous exchange between parties with no time delay or opportunity to back out. If NEAD chains are to reach their full promise for large-scale, nonsimultaneous organ transfer, legal uncertainties and sociological ambiguities must be finessed, both in the practices of the coordinating agencies and in the minds of NEAD-chain participants. This might happen either through the further elaboration of gift-like language and practices, or through a creative use of the cultural form and motivational vocabulary, but not necessarily the legal and institutional machinery, of contract.

    Full Text Available Sabe-se que, durante alguns períodos da história, a Música e a Matemática foram ciências que compartilharam seus conceitos e discussões. Um dos períodos no qual essa comunhão se deu de maneira significativa foi o Renascimento. A Música era então classificada como ciência e, pertencendo ao grupo das matemáticas, dividia seu espaço com a Aritmética, a quem era subordinada, com a Geometria e a Astronomia. Essa divisão foi transmitida através das obras do filósofo Sevério N. Boécio e prevaleceu durante o século XVI, juntamente da noção de subalternação das ciências, provida na obra de Aristóteles e de seus comentaristas. Contudo, durante a segunda metade do século XVI, o cenário teórico foi sofrendo questionamentos e sendo por vezes reformulado. Tais reformulações tomaram várias formas, todavia, foi no diálogo entre dois autores específicos, Gioseffo Zarlino (1517-1590 e Vincenzo Galilei (1533?-1591, que a estrutura vigente foi realmente abalada. Neste artigo, pretendese mostrar a relevância da subalternação das ciências na discussão metodológica para a pretendida reformulação teórica, visto que um dos problemas metodológicos centrais da demonstração nas ciências matemáticas do século XVI foi a reconciliação entre as condições ideais, que governavam o mundo matemático, no caso específico o da Aritmética, e as condições reais do mundo físico natural.

    The recently developed method of constructing the nuclear exchange current operators within the framework of the topological soliton (Skyrme) model is described. This approach is theoretically compact, allows treating nucleon and nuclear structure on the same footing and finally can be viewed as an effective low-energy representation of QCD. The approach also leads to some very natural connections between pionic and nuclear transition rates because the effective pion-nucleon interaction involves the isovector (exchange) current operator. Finally, a discussion of the relation between exchange currents and relativistic corrections is given. (author). 76 refs, 6 figs

    An annular heat exchanger assembly includes a plurality of low thermal growth ceramic heat exchange members with inlet and exit flow ports on distinct faces. A mounting member locates each ceramic member in a near-annular array and seals the flow ports on the distinct faces into the separate flow paths of the heat exchanger. The mounting member adjusts for the temperature gradient in the assembly and the different coefficients of thermal expansion of the members of the assembly during all operating temperatures.

    The conservation of crop genetic resources requires understanding the different variables-cultural, social, and economic-that impinge on crop diversity. In small-scale farming systems, seed exchanges represent a key mechanism in the dynamics of crop genetic diversity, and analyzing the rules that structure social networks of seed exchange between farmer communities can help decipher patterns of crop genetic diversity. Using a combination of ethnobotanical and molecular genetic approaches, we investigated the relationships between regional patterns of manioc genetic diversity in Gabon and local networks of seed exchange. Spatially explicit Bayesian clustering methods showed that geographical discontinuities of manioc genetic diversity mirror major ethnolinguistic boundaries, with a southern matrilineal domain characterized by high levels of varietal diversity and a northern patrilineal domain characterized by low varietal diversity. Borrowing concepts from anthropology--kinship, bridewealth, and filiation--we analyzed the relationships between marriage exchanges and seed exchange networks in patrilineal and matrilineal societies. We demonstrate that, by defining marriage prohibitions, kinship systems structure social networks of exchange between farmer communities and influence the movement of seeds in metapopulations, shaping crop diversity at local and regional levels.

    The conservation of crop genetic resources requires understanding the different variables—cultural, social, and economic—that impinge on crop diversity. In small-scale farming systems, seed exchanges represent a key mechanism in the dynamics of crop genetic diversity, and analyzing the rules that structure social networks of seed exchange between farmer communities can help decipher patterns of crop genetic diversity. Using a combination of ethnobotanical and molecular genetic approaches, we investigated the relationships between regional patterns of manioc genetic diversity in Gabon and local networks of seed exchange. Spatially explicit Bayesian clustering methods showed that geographical discontinuities of manioc genetic diversity mirror major ethnolinguistic boundaries, with a southern matrilineal domain characterized by high levels of varietal diversity and a northern patrilineal domain characterized by low varietal diversity. Borrowing concepts from anthropology—kinship, bridewealth, and filiation—we analyzed the relationships between marriage exchanges and seed exchange networks in patrilineal and matrilineal societies. We demonstrate that, by defining marriage prohibitions, kinship systems structure social networks of exchange between farmer communities and influence the movement of seeds in metapopulations, shaping crop diversity at local and regional levels.

    The deuterium exchange plant is combined with an absorption refrigeration plant in order to improve the exchange process and to produce refrigeration. The refrigeration plant has a throttling means for expanding and cooling a portion of the liquid exchange medium separated in the exchange plant as well as an evaporator, in which the said liquid exchange medium is brought into heat exchange with a cold consumer device, absorption means for forming a solution of the used exchange medium and fresh water and a pump for pumping the solution into the exchange plant

    Full Text Available Accumulating foreign exchange reserves, despite their cost and their impacts on other macroeconomics variables, provides some benefits. This paper models such foreign exchange reserves. To measure the adequacy of foreign exchange reserves for import, it uses total reserves-to-import ratio (TRM. The chosen independent variables are gross domestic product growth, exchange rates, opportunity cost, and a dummy variable separating the pre and post 1997 Asian financial crisis. To estimate the risky TRM value, this paper uses conditional Value-at-Risk (VaR, with the help of Glosten-Jagannathan-Runkle (GJR model to estimate the conditional volatility. The results suggest that all independent variables significantly influence TRM. They also suggest that the short and long run volatilities are evident, with the additional evidence of asymmetric effects of negative and positive past shocks. The VaR, which are calculated assuming both normal and t distributions, provide similar results, namely violations in 2005 and 2008.

    This volume records the Proceedings of the sixteenth conference in the biennial Sensors and Their Applications series which took place at the Clarion Hotel, Cork, Ireland between 12-14 September 2011. The conference is organized by the Instrument Science and Technology Group of the Institute of Physics. On this occasion, the conference was hosted by Tyndall National Institute at University College Cork. This year the conference returns to Ireland, having last been held in Limerick in 2003. The conference proceedings record the continuing growth of the sensors community nationally and internationally. The conferences bring together contributions from scientists and engineers from academia, research institutes and industrial establishments, and therefore provide an excellent opportunity for these communities to present and discuss the latest results in the field of sensors, instrumentation and measurement. Amongst the more traditional themes, such as optical sensing, there is growth in new areas such as biomedical sensing and instrumentation, and nanosensing, which is reflected in this volume. Similarly the contribution of modelling and simulation techniques in sensor and instrumentation design and their applications is acknowledged by a session in this area. The sessions across the conference are supported by notable contributions from invited speakers. We would like to thank all of our colleagues in the sensor and instrumentation community who have supported this event by contributing manuscripts. Our thanks also go to Tyndall National Institute for hosting this conference and all the sponsors who, with their generous financial and in-kind contributions, enabled the better organization of this conference. We would also like to thank all the members of the Instrument Science and Technology Group for their support, and in particular for refereeing the submitted manuscripts. We are also pleased to express our thanks to the Conference Department of the Institute of Physics for their invaluable support in organising this event. We are especially grateful to Dawn Stewart for her responsive and efficient day-to-day handling of this event, as well as to Claire Garland for her planning and management of this event. We hope that the conference authors, participants and a wider audience will find these proceedings to be of interest and to serve as a useful reference text.

    In this essay we identify a characteristic pattern of Heraclitus’ thought and language, the “figure of reversible exchange”. We suggest that this figure allows Heraclitus to propose an ontological structure consisting of two intersecting circuits of relations: a pre-temporal reversible exchange between Being and Becoming and between One and Many, and a temporal reversible exchange within the Many as the very process of Becoming. Against Richard Seaford’s interpretation of Heraclitus’ thought ...

    2006-12-01

    Full Text Available El presente trabajo realiza una revisión bibliográfica de los tratados pedagógicos de teneduría de libros en el Reino Unido desde el siglo XVI, cuando se incorporó la partida doble, hasta finales del siglo XIX.Los rasgos didácticos más significativos de los primeros 250 años de docencia en teneduría de libros se resumen en la importancia que se concede al Libro Diario. Con el desarrollo de la partida doble se hizo habitual ampliar el significado de los términos débito y crédito más allá de la connotación personal original y aplicarlos a objetos inanimados y conceptos abstractos. La exposición mediante la personificación de cuentas consistía en un aprendizaje memorístico apoyado en normas y versificación.La disputa entre los que eran partidarios del Diario y aquellos que preferían el Mayor como libro de enseñanza, no era otra cosa más que la traducción del conflicto entre el enfoque memorístico y el racional de la teneduría de libros. Los seguidores del enfoque del Mayor salieron doblemente reforzados: significaba una enseñanza más racional y un cambio en las exigencias de los negocios.El Diario perdió su posición dominante cuando, a mediados del siglo XIX, surgió una teoría alternativa a la personificación de las cuentas. Se trata de la teoría de la propiedad de las cuentas y se ocupa del significado de éstas desde el punto de vista del propietario.The present paper makes a bibliographic checking of the pedagogic treatises of bookkeeping in the United Kingdom since 16th Century, when the double-entry system was introduced, up to the end of 19th Century.The most outstanding didactic feature of the first 250 years of bookkeeping teaching could be summed up in the prevalent role the Journal was given. With the development of the double-entry system, it became common extending the meaning of the terms debit and credit beyond the original personal connotation and applying them to inanimate objects and abstract

  20. Entre Hacienda Real y poderes locales: los intentos de reformar las finanzas municipales del reino de Napóles en los siglos XVI y XVII

    2009-12-01

    Full Text Available RESUMEN: Durante los sesenta años de transición entre los siglos XVI y XVII se concentran los mayores esfuerzos llevados a cabo en la edad de los Austrias para aumentar el control del poder central sobre la gestión de las finanzas municipales del reino de Napóles, con la doble finalidad de garantizar la regularidad del producto fiscal proveniente de las comunidades y, al mismo tiempo, constituir una reserva de capitales a la cual el soberano pudiera acceder con facilidad y con condiciones menos onerosas que las aplicadas habitualmente por los banqueros. Ambas finalidades son la consecuencia de las crecientes exigencias financieras de la Corona que se registran en el mismo período y que llevan a un crecimiento rápido y vertiginoso de los recursos enviados fuera de los límites del reino, principalmente a Lombardía o a Flandes, para asistir a los ejércitos de la Monarquía. A pesar de la determinación demostrada, la Hacienda Real nunca consigue controlar de una forma completa las finanzas urbanas, sobre todo por la oposición de los poderes económicos —tanto de la capital y como de las provincias del reino— que habrían resultado afectados. A partir de los años 30 del siglo XVII los proyectos de reforma se retiran a cambio del compromiso de los patriciados de las ciudades de cobrar los impuestos y enviarlos a la Corte del modo más puntual. Profundizar en las modalidades a través de las cuales estos proyectos de reformas son llevados a cabo,aunque de modo inacabado, permite comprender mejor la índole de las finanzas urbanas como espacio de poder contendido entre élites dirigentes ciudadanas y Hacienda Real.ABSTRACT: The most important efforts to reform the urban finances realized in the Kingdom of Naples at the time of Spanish rule were done between 1570 and 1630. The increasing financial needing, due to an enormous military expense, obliged the Spanish Monarchy to make any attempt in order to insure the regularity of the tax

  1. Electrically switched cesium ion exchange

    Electrically Switched Ion Exchange (ESIX) is a separation technology being developed as an alternative to conventional ion exchange for removing radionuclides from high-level waste. The ESIX technology, which combines ion exchange and electrochemistry, is geared toward producing electroactive films that are highly selective, regenerable, and long lasting. During the process, ion uptake and elution are controlled directly by modulating the potential of an ion exchange film that has been electrochemically deposited onto a high surface area electrode. This method adds little sodium to the waste stream and minimizes the secondary wastes associated with traditional ion exchange techniques. Development of the ESIX process is well underway for cesium removal using ferrocyanides as the electroactive films. Films having selectivity for perrhenate (a pertechnetate surrogate) over nitrate also have been deposited and tested. A case study for the KE Basin on the Hanford Site was conducted based on the results of the development testing. Engineering design baseline parameters for film deposition, film regeneration, cesium loading, and cesium elution were used for developing a conceptual system. Order of magnitude cost estimates were developed to compare with conventional ion exchange. This case study demonstrated that KE Basin wastewater could be processed continuously with minimal secondary waste and reduced associated disposal costs, as well as lower capital and labor expenditures

    Full Text Available Resumo Um dos maiores desafios enfrentados pelos colonizadores europeus, na América portuguesa quinhentista, foi a adaptação ao novo ambiente, sobretudo, aos obstáculos nutricionais. Prover-se das calorias exigidas diariamente pelo corpo humano pode ter sido uma das tarefas mais extenuantes da dinâmica colonial. A alimentação era feita de acordo com a disponibilidade dos gêneros alimentícios ali existentes. Nesse contexto, os frutos nativos assumiram um papel importante na dieta alimentar daqueles homens, principalmente quando consumidos em forma de compotas e conservas. Temos, como objetivo, destacar a importância dos doces coloniais, bem como identificar de que maneira o seu consumo ocorria, sinalizando a relação dessa atividade com o discurso médico difundido na Europa do século XVI.

    Full Text Available En Tunja y Santafé, la prosperidad económica de los colonizadores, especialmente la de los beneficiados con la posesión de encomiendas, se basaba en el aprovechamiento de los recursos provenientes de las comunidades indígenas, especialmente de la mano de obra. Como expuso Villamarín, durante el siglo XVI los principales puntos de encuentro entre colonizadores e indígenas estuvieron relacionados con el trabajo. El trabajo funcionaba como forma de tributo en las encomiendas, pues durante una buena parte este siglo, las tasas de tributos elaboradas por la Corona imponían a las comunidades la obligación de cultivar para el encomendero labranzas de maíz, trigo, cebada y papas.

    Full Text Available The Strait of Magellan was one of the geographical areas which generated more attention in the cartographers during the XVI and XVII centuries. In fact, for the Chilean case, together with Chiloe and Valdivia, the Magellanic region is the most represented. The reasons are both navigational and strategic purposes. That means that the surviving examples on public and private archives of several countries are comparatively abundant. The present study shows a new piece, which forms part of a navigational chart or «Derrotero» that is conserved in the Historical Archive of the Peruvian Navy, whose dating is roughly the early XVII century, although showing geographical representations from the previous century.El estrecho de Magallanes fue uno de los territorios que mayor atención despertó en los cartógrafos de los siglos XVI y XVIII. De hecho, para el caso chileno, junto a Chiloé y Valdivia, el territorio magallánico es el más importante en cuanto a representación geográfica, siendo razones de navegación así como estratégicas las que explican la gran cantidad de fuentes cartográficas existentes en archivos públicos y privados nacionales como extranjeros. El presente estudio da a conocer una nueva pieza que forma parte de un derrotero que se conserva en el Archivo de la Marina de Guerra del Perú, cuya datación aproximada es de comienzos del siglo XVII, aunque con representaciones geográficas del siglo anterior.

  6. Tokamak rotation and charge exchange

    In the absence of momentum input, tokamak toroidal rotation rates are typically small - no larger in particular than poloidal rotation - even when the radial electric field is strong, as near the plasma edge. This circumstance, contradicting conventional neoclassical theory, is commonly attributed to the rotation damping effect of charge exchange, although a detailed comparison between charge-exchange damping theory and experiment is apparently unavailable. Such a comparison is attempted here in the context of recent TEXT experiments, which compare rotation rates, both poloidal and toroidal, in helium and hydrogen discharges. The helium discharges provide useful data because they are nearly free of ion-neutral charge exchange; they have been found to rotate toroidally in reasonable agreement with neoclassical predictions. The hydrogen experiments show much smaller toroidal motion as usual. The theoretical calculation uses the full charge-exchange operator and assumes plateau collisionality, roughly consistent with the experimental conditions. The authors calculate the ion flow as a function of v cx /v c , where v cx is the charge exchange rate and v c the Coulomb collision frequency. The results are in reasonable accord with the observations. 1 ref

  7. Fair Exchange in Strand Spaces

    Directory of Open Access Journals (Sweden)

    Joshua D. Guttman

    2009-10-01

    Full Text Available Many cryptographic protocols are intended to coordinate state changes among principals. Exchange protocols coordinate delivery of new values to the participants, e.g. additions to the set of values they possess. An exchange protocol is fair if it ensures that delivery of new values is balanced: If one participant obtains a new possession via the protocol, then all other participants will, too. Fair exchange requires progress assumptions, unlike some other protocol properties. The strand space model is a framework for design and verification of cryptographic protocols. A strand is a local behavior of a single principal in a single session of a protocol. A bundle is a partially ordered global execution built from protocol strands and adversary activities. The strand space model needs two additions for fair exchange protocols. First, we regard the state as a multiset of facts, and we allow strands to cause changes in this state via multiset rewriting. Second, progress assumptions stipulate that some channels are resilient-and guaranteed to deliver messages-and some principals are assumed not to stop at certain critical steps. This method leads to proofs of correctness that cleanly separate protocol properties, such as authentication and confidentiality, from invariants governing state evolution. G. Wang's recent fair exchange protocol illustrates the approach.

    This research is focused on improving the efficiency of the anion exchange process for purifying plutonium. While initially focused on plutonium, the technology could also be applied to other ion-exchange processes. Work in FY17 focused on the improvement and optimization of porous foam columns that were initially developed in FY16. These foam columns were surface functionalized with poly(4-vinylpyridine) (PVP) to provide the Pu specific anion-exchange sites. Two different polymerization methods were explored for maximizing the surface functionalization with the PVP. The open-celled polymeric foams have large open pores and large surface areas available for sorption. The fluid passes through the large open pores of this material, allowing convection to be the dominant mechanism by which mass transport takes place. These materials generally have very low densities, open-celled structures with high cell interconnectivity, small cell sizes, uniform cell size distributions, and high structural integrity. These porous foam columns provide advantages over the typical porous resin beads by eliminating the slow diffusion through resin beads, making the anion-exchange sites easily accessible on the foam surfaces. The best performing samples exceeded the Pu capacity of the commercially available resin, and also offered the advantage of sharper elution profiles, resulting in a more concentrated product, with less loss of material to the dilute heads and tails cuts. An alternate approach to improving the efficiency of this process was also explored through the development of a microchannel array system for performing the anion exchange.

    Full Text Available A method has been developed whereby diffusion and exchange in micro cellular structures in the human brain are correlated to produce a new type of image contrast leading to determination of water exchange rates in vivo. The diffusion method relies on differential apparent diffusion coefficients as detectable nuclei exchange between adjacent compartments marked with different apparent diffusion coefficient values (e.g. intra- and extra-cellular compartments. A new pulse sequence was developed, and used to calculate water intra/extra mean residence times in brain, and the signal dependence on various experimental parameters was analysed. The method was tested in vivo at 3T field strength and produced 160 ms and 550 ms for extra-cellular and intra-cellular mean residence times, respectively.

    Pulmonary gas exchange was continuously measured in 13 mechanically ventilated patients during 24 hemodialyses for acute renal failure. Minute-ventilation was maintained constant by controlled ventilation and gas exchange was continuously measured by a mass-spectrometer system. Three groups were compared: a cuprophan membrane with an acetate dialysate; a polyacrilonitrile membrane (PAN) with an acetate dialysate; and PAN with a bicarbonate dialysate. Arterial PO2 and the O2 alveolar-arterial gradient were the same regardless of the membrane used. [H+] mildly decreased with all dialysates used. Arterial PCO2 decreased only with the acetate dialysate. O2 consumption increased, up to 20 +/- 5% of the initial values during hemodialysis, and remained increased during the two hours following the hemodialysis. Respiratory exchange ratio was lower after than before the hemodialysis. the maintenance of a constant minute ventilation prevented hemodialysis induced hypoxemia. VO2 increased during hemodialysis.

  17. Compact heat exchanger for power plants

    2001-01-01

    Vahterus Oy, located at Kalanti, has manufactured heat exchangers since the beginning of 1990s. About 90% of the equipment produced are exported. In the PSHE (Plate and Shell) solution of the Vahterus heat exchanger the heat is transferred by round plated welded to form a compact package, which is assembled into a cylindrical steel casing. The heat exchanger contains no gaskets or soldered joints, which eliminates the leak risks. Traditional heat exchanges are usually operated at higher temperatures and pressures, but the heat transfer capacities of them are lower. Plate heat exchangers, on the other hand, are efficient, but the application range of them is narrow. Additionally, the rubber gasket of the heat exchange plates, sealing the joints of the heat exchanging plates, does not stand high pressures or temperatures, or corroding fluids. The new welded plate heat exchanger combine the pressure and temperature resistance of tube heat exchangers and the high heat exchange capacity of plate heat exchangers. The new corrosion resisting heat exchanger can be applied for especially hard conditions. The operating temperature range of the PSHE heat exchanger is - 200 - 900 deg C. The pressure resistance is as high as 100 bar. The space requirement of PSHE is only one tenth of the space requirement of traditional tube heat exchangers. Adjusting the number of heat exchanging plates can change the capacity of the heat exchanger. Power range of the heat exchanger can be as high as 80 MW. Due to the corrosion preventive construction and the small dimension the PSHE heat exchanger can be applied for refrigerators using ammonia as refrigerant. These kinds of new Vahterus heat exchangers are in use in 60 countries in more than 2000 refrigerators

    Full Text Available After a brief setup on musicological studies on the relationships between Naples and Spain, in particular in the keyboard production of the sixteenth and seventeenth centuries, this paper occupies almost exclusively - on analysis and style - on the LIBRO DI RICERCATE A QVATTRO VOCI DI ROCCO RODIO CON ALCVNE FANTASIE SOPRA VARII CANTI FERMI, published in Naples by Gioseppe Cacchio dall’Aquila in 1575. The book by Rocco Rodio (“Rocchus Rodius Civitatis Barensis”; Bari-Napoli 1530ca, 1615ca is the fi rst release ever appeared in score, which was particularly followed in Naples in the late sixteenth and early seventeenth century and of which we find significant use in Italy and Europe throughout the course of the seventeenth century, with examples also in the eighteenth century. The analysis of form and style of the compositions contained in this printing shows the ‘Modern’ and progressive author’s writing, which seems refractory to the contemporary practice of improvisation and ‘diminutions’ that was practiced in the polyphonic motet and madrigale affettuoso; the fantasies are a superb example of invention and mastery of composition to be read not only in the flow of tradition practiced on the harpsichord, but should be understood as the exemplary model resulted in the broader vocal, didactic and experimental literature of the polyphonic instrumental schools in Naples, Rome and Spain.Tras un breve repaso de los estudios musicológicos centrados en las relaciones que la música para tecla de los siglos XVI y XVII creó entre Nápoles y España, el ensayo se centra de manera casi exclusiva, y desde un punto de vista analítico y estilístico, en el «Libro di ricercate a qvattro voci di Rocco Rodio con alcvne fantasie sopra Varii canti fermi» publicado en Nápoles por Gioseppe Cacchio dall’Aquila en el 1575.

    1992-02-01

    The structural integrity demonstration of the primary coolant piping system includes evaluating the structural capacity of each component against a large break or equivalent Double-Ended Guillotine Break. A large break at the inlet or outlet heads of the heat exchangers would occur if the restraint members of the heads become inactive. The structural integrity of the heads is demonstrated by showing the redundant capacity of the staybolts to restrain the head at design conditions and under seismic loadings. The Savannah River Site heat exchanger head is attached to the tubesheet by 84 staybolts. Access to the staybolts is limited due to a welded seal cap over the staybolts. An ultrasonic testing (UT) inspection technique to provide an in-situ examination of the staybolts has recently been developed at SRS. Examination of the staybolts will be performed to ensure their service condition and configuration is within acceptance limits. An acceptance criteria methodology has been developed to disposition flaws reported in the staybolt inspections while ensuring adequate restraint capacity of the staybolts to maintain integrity of the heat exchanger heads against collapse. The methodology includes an approach for the baseline and periodic inspections of the staybolts. The heat exchanger head is analyzed with a three-dimensional finite element model. The restraint provided by the staybolts is evaluated for several postulated cases of inactive or missing staybolts. Evaluation of specific, inactive staybolt configurations based on the UT results can be performed with the finite element model and fracture methodology in this report

  12. Charge exchange in galaxy clusters

    Context. Though theoretically expected, the charge exchange emission from galaxy clusters has never been confidently detected. Accumulating hints were reported recently, including a rather marginal detection with the Hitomi data of the Perseus cluster. As previously suggested, a detection of charge exchange line emission from galaxy clusters would not only impact the interpretation of the newly discovered 3.5 keV line, but also open up a new research topic on the interaction between hot and cold matter in clusters. Aim. We aim to perform the most systematic search for the O VIII charge exchange line in cluster spectra using the RGS on board XMM-Newton. Methods: We introduce a sample of 21 clusters observed with the RGS. In order to search for O VIII charge exchange, the sample selection criterion is a >35σ detection of the O VIII Lyα line in the archival RGS spectra. The dominating thermal plasma emission is modeled and subtracted with a two-temperature thermal component, and the residuals are stacked for the line search. The systematic uncertainties in the fits are quantified by refitting the spectra with a varying continuum and line broadening. Results: By the residual stacking, we do find a hint of a line-like feature at 14.82 Å, the characteristic wavelength expected for oxygen charge exchange. This feature has a marginal significance of 2.8σ, and the average equivalent width is 2.5 × 10-4 keV. We further demonstrate that the putative feature can be barely affected by the systematic errors from continuum modeling and instrumental effects, or the atomic uncertainties of the neighboring thermal lines. Conclusions: Assuming a realistic temperature and abundance pattern, the physical model implied by the possible oxygen line agrees well with the theoretical model proposed previously to explain the reported 3.5 keV line. If the charge exchange source indeed exists, we expect that the oxygen abundance could have been overestimated by 8-22% in previous X

  13. Compact Ceramic Microchannel Heat Exchangers

    Energy Technology Data Exchange (ETDEWEB)

    Lewinsohn, Charles [Ceramatec, Inc., Salt Lake City, UT (United States)

    2016-10-31

    The objective of the proposed work was to demonstrate the feasibility of a step change in power plant efficiency at a commercially viable cost, by obtaining performance data for prototype, compact, ceramic microchannel heat exchangers. By performing the tasks described in the initial proposal, all of the milestones were met. The work performed will advance the technology from Technology Readiness Level 3 (TRL 3) to Technology Readiness Level 4 (TRL 4) and validate the potential of using these heat exchangers for enabling high efficiency solid oxide fuel cell (SOFC) or high-temperature turbine-based power plants. The attached report will describe how this objective was met. In collaboration with The Colorado School of Mines (CSM), specifications were developed for a high temperature heat exchanger for three commercial microturbines. Microturbines were selected because they are a more mature commercial technology than SOFC, they are a low-volume and high-value target for market entry of high-temperature heat exchangers, and they are essentially scaled-down versions of turbines used in utility-scale power plants. Using these specifications, microchannel dimensions were selected to meet the performance requirements. Ceramic plates were fabricated with microchannels of these dimensions. The plates were tested at room temperature and elevated temperature. Plates were joined together to make modular, heat exchanger stacks that were tested at a variety of temperatures and flow rates. Although gas flow rates equivalent to those in microturbines could not be achieved in the laboratory environment, the results showed expected efficiencies, robust operation under significant temperature gradients at high temperature, and the ability to cycle the stacks. Details of the methods and results are presented in this final report.

Por un lado, durante los tiempos prehispánicos, los objetos de metal y la producción metalúrgica acreditaron una alta valorización social. Por otro, la obtención de ganancias a partir del aprovechamiento minero se desarrolló como la actividad primordial detrás de los procesos de conquista y colonización del Nuevo Mundo durante los siglos XVI y XVII. Mientras es conocido que la extracción de metal fue uno de los principales espacios de explotación de mano de obra indígena en el Alto Perú, poco interés tuvo su análisis en el contexto de las rebeliones indígenas ocurridas en el valle Calchaquí hasta 1665. El objetivo es abordar los conflictos desplegados en esta región durante los siglos XVI y XVII tomando como eje la minería y metalurgia en la Antigua Gobernación del Tucumán.Mining activity and metallurgical production were aspects that played important roles during the history of the native Northwestern Argentine population. On the one hand, during the prehispanic times, metal objects and metallurgical production had a high social value.

While it is known that the extraction of metal was one of the main elements of exploitation of indigenous labor force in Alto Peru, little attention has been paid to its analysis in the context of the native rebellions in the Calchaqui valley before 1665. The objective is to study the conflicts in this area during the 16th and 17th centuries, focusing on mining and metallurgy in the Antigua Gobernación del Tucumán.

    1975-01-01

    A heat exchanger incorporating steam superheating is proposed suitable for nuclear power plants having heat transfer surfaces housed in the pressure vessel. The heat exchanger is characterized by the fact that on the primary side the steam overheating surface is parallel to the afterheating and evaporating surfaces. The parallel heat transfer surfaces, afterheating and evaporating surfaces are connected to a common tube plate. The superheated steam outlet is formed by the central tube, the saturated steam by-pass channel is formed by a concentric tube. The steam superheating surface is formed by a cluster of U-tubes. Spatial U-tubes form the afterheating and the evaporating surfaces outside of the superheating surface. (Oy)

    Calculations of pion single charge exchange using the PWIA and DWIA are presented. Emphasis is given to the effects of absorbtion and blocking. A microscopic calculation of the 0 0 excitation and low energy angular distribution is in excellent agreement with the data. A fixed nucleon multiple scattering calculation of the pion double charge exchange reaction is presented. Various valence neutron wave functions are used, and the contributions of different spatial orientations of the last two neutrons to the reaction are examined. The DCX cross section is found to be very sensitive to the inclusion of correlations in the two-neutron wave function. Satisfactory agreement with DCX data on 14 C can be obtained using a nucleonic picture of the nucleus

  11. DIVALENT ION EXCHANGE WITH ALKALI

    Energy Technology Data Exchange (ETDEWEB)

    Bunge, A.L.; Klein, G.; Radke, C.J.

    1980-05-01

    Exchange of hardness ions is important in enhanced oil recovery with chemical additives. In both micellar-polymer and caustic flooding processes, multivalent ions released from rock surfaces can interact with anionic surfactants, rendering them preferentially oil soluble and/or insoluble in water. Because hardness cations are sparingly soluble and precipitate in alkaline solutions, such solutions may be more efficient as surfactant flood preflushes than are softened brines. Multivalent ion precipitation may also occur in alkaline waterflooding. To permit design of such processes, this paper presents a chromatographic theory for simultaneous ion exchange with precipitation of divalent ions. Theoretical effluent histories and concentration profiles are presented for the cases of finite pulses and continuous injection of hydroxide ions into linear cores. Complete capture of the insoluble salt particles is assumed. Results are given for the case of instantaneous equilibration of the solution with the precipitate, as well for the case of complete nonequilibrium, in which the solid precipitate does not redissolve. The efficiency of alklaine preflushing is shown to depend on the exchange isotherm, initial divalent loading of the rock, injected pH and salinity, the solubility product of the precipitated salt, and pulse size. The effect of slug size on complete equilibrium removal of hardness ions is reduced efficiency with increasing size until a critical volume approximating continuous injection is reached. Increasing injected pH and salinity provides a more favorable response. Experimental data for Berea sandstone and an argillaceous sand compare favorably with the proposed theory.

    A further study of exchange of the cobalt atoms in solid Co(H/sub 2/O)/sub 6/(Co EDTA)/sub 2/ x 4H/sub 2/O has been made. The exchange is more easily measured when the compound has been ..gamma.. irradiated before heating. Without irradiation the exchange is complicated by substantial concurrent thermal decomposition. Vacuum dehydration to the tetrahydrate can be effected at 366 K without appreciable exchange. A relation between exchange, annealing of radiolytic decomposition and thermal decomposition in such compounds is suggested.

    Full Text Available At the end of the XVI century, the Spanish empire had the necessity to create a series of strategies to access deposits of metal deposits located them in the North of Nueva España. These metal deposits were very important to the colony economy. The porpouse of this text in to analize the colonization and pacification policy that the Spanish goverment used in the North of Nueva Galicia during this history period of time, in which a group of tlaxcaltecas families took the leading role. The method used en this research is the historical reconstruction, which give us elements to build up all the past events of the differents sources —vestiges and testimonies— already analized. All this let us know a successfuly colonial policy which help the colonial government to extracted the silver, and also contribuid to legitimize the expansion of tlaxcalteca people in North of Nueva España. Also we conclude two kinds of aculturation: the macroestructural and the microestructural, both affecting in a considerate way the two different social groups wich consider in the same space.

    Full Text Available Este texto tiene como objetivo destacar la relación entre la proyección política de la Monarquía Hispánica en sus territorios de Ultramar y la acción evangelizadora. Las particularidades de la Iglesia indiana potenciaron la labor del clero regular, cuya influencia se extendió desde el ámbito de lo religioso hacia todas las esferas de la vida en las nuevas sociedades americanas. Evangelizar significó ante todo crear una identidad colectiva católica y, con ella, la base de la adhesión de los naturales al dominio del rey de España. Para ello destacamos la 'conquista espiritual' como un proceso paralelo y fuertemente ligado a la 'conquista militar', marcado por la violencia de una fe impositiva, anuladora del pasado prehispánico. Lo hacemos a través de imágenes y testimonios del siglo XVI que interpretaron los acontecimientos del cambio que dio lugar a la América hispánica.

    Prior to the fixation of radioactive ion exchangers into bitumen these exchangers have to be dried. The resulting gaseous products may generate explosive mixtures. An analysis was made of the thermal stability of two types of ion exchangers, the cation exchanger KU-2-8 cS and the anion exchanger AV-17-8 cS which are used in the V-1 nuclear power plant at Jaslovske Bohunice. The thermal stability of the anion exchangers was monitored using gas chromatography at temperatures of 100, 120, 140, 160 and 180 degC and by measuring weight loss by kiln-drying at temperatures of 120, 140, 160 and 180 degC. The ion exchanger was heated for 6 hours and samples were taken continuously at one hour intervals. The thermal stability of the cation exchanger was monitored by measuring the weight loss. Gas chromatography showed the release of trimethylamine from the anion exchanger in direct dependence on temperature. The measurement of weight losses, however, only showed higher losses of released products which are explained by the release of other thermally unstable products. The analysis of the thermal stability of the cation exchanger showed the release of SO 2 and the weight loss (following correction for water content) was found only after the fourth hour of decomposition. The experiment showed that the drying of anion exchanger AV-17-8 cS may cause the formation of explosive mixtures. (J.P.)

    1990-10-23

    An improvement in purification of scandium through ion exchange chromatography is disclosed in which the oxidation potential of the eluting solution is altered by the addition of potassium chlorate or ammonium chloride so that removal of contaminants is encouraged. The temperature, pH and concentration of the eluent HEDTA are controlled in order to maintain the scandium in the column while minimizing dilution of the scandium band. Recovery of scandium is improved by pumping dilute scandium over the column prior to stripping the scandium and precipitation. This eliminates the HEDTA ion and other monovalent cations contaminating the scandium band. This method maximizes recovery of scandium while maintaining purity. 2 figs.

    1976-01-01

    The invention refers to a system for cooling process or operation fluids, in which the local or general superheating of the coolant must be avoided. It particularly applies to the bleed fluid of a nuclear power station steam generator. This invention aims to create a heat exchange system that uses static components only and that is therefore completely reliable whilst remaining simple and relatively economical. This system includes a regeneration heat exchanger (with a primary and secondary system) and a triple flow heat exchanger with three circuits. The first and second circuits are in fluid communication with the primary and secondary circuits of the regeneration heat exchanger. The fluid communication between the regeneration heat exchanger and the triple circuit heat exchanger is such that the process fluid first goes through one of the circuits of the regeneration heat exchanger where it is cooled, then through one of the first two circuits of the triple circuit heat exchanger where it is cooled still more, then through the other of the circuits of the regeneration exchanger where it is heated and finally through the second of the first two circuits of the triple circuit heat exchanger where it is cooled again. A coolant flows through the third circuit in order to cool the process fluid concerned [fr

    Ning, Ye; Wang, Yiming; Su, Chi-wei

    2017-10-01

    This study compares the market efficiency of China's onshore and offshore foreign exchange markets before and after the foreign exchange reform on August 11, 2015. We use the multifractal detrended fluctuation analysis of the onshore and offshore RMB/USD spot exchange rate series as basis. We then find that the onshore foreign exchange market before the reform has the lowest market efficiency, which increased after the reform. The offshore foreign exchange market before the reform has the highest market efficiency, which dropped after the reform. This finding implies the increased efficiency of the onshore foreign exchange market and the loss of efficiency in the offshore foreign exchange market. We also find that the offshore foreign exchange market is more efficient than the onshore market and that the gap shrank after the reform. Changes in intervention of the People's Bank of China since the reform is a possible explanation for the changes in the efficiency of the foreign exchange market.

  18. Isotope exchange process and device

    Delvalle, Pierre.

    1974-01-01

    A process for enriching uranium in one of its isotopes is described. To do so, cascade isotopic exchanges are made by contact between U(III) and U(IV) in conditions avoiding the oxidation of U(III) in U(IV). A liquid phase containing an uranium compound and free of other group III to VIII metals of the periodic classification, in which uranium is present at a first valence is placed in contact with a second valence uranium compound, protected from any contact with a conducting solid and with an agent bringing free or release oxygen. The second phase is organic. The process includes a counter current isotopic exchange between an aqueous phase containing a U +4 salting-out agent and the uranium as U +3 ions and an organic phase containing the uranium at valence IV. This is followed by the extraction of U(IV) from the organic phase into the previously spent aqueous phase and the reduction of uranium from valence IV to valence III; finally by oxidation of U(III) of the aqueous phase into U(IV) and the transfer of U(IV) into the previously exhausted organic phase [fr

  19. Geographic exchange standard and primer

    Energy Technology Data Exchange (ETDEWEB)

    1978-10-01

    The ANSI Draft Proposal Specifications for an Information Interchange Data Descriptive File, X3L5.SEP, contains some Guidelines for Implementation (Appendix D). However, some additional guidelines should be provided specifically for the more commonly used systems of coding locational data, and referring thematic data to those codes. While there is no consensus that a single, preferred representation of geographical files can be specified as a standard for exchange, there is agreement on the generic form of record structures for commonly used, two-dimensional files. This report surveys by example common practice and illustrates the use of geocodes as thematic data pointers. It defines the elements of the structures as a subsystem within the interchange standard. An implementation within the Levels of Implementation of the basic IWGDE Standard is proposed and examples for some of the defined file types are presented in numerical form to aid in understanding. The problem of referring thematic data to a geographic file when these data reside in a physically distinct exchange file is discussed. 14 figures, 1 table. (RWR)

    Phase-exchange thermoacoustic engines are reliable machines holding great promise in converting heat from low grade heat sources to mechanical or electrical power. In these engines the working fluid is a gas mixture containing one condensable component, decreasing the temperature difference required for ignition and steady state operation. Our experimental setup consists of a vertical acoustic resonator containing a mixture of air-water vapor. Water evaporates near the heat source, condenses at the heat sink and is drawn back down by gravity and capillary forces where it re-evaporates, sustaining a steady state closed thermodynamic cycle. We investigated the stability limit, namely the critical point at which temperature difference in the engine enables onset of self-excited oscillations, and the steady state of the engine. A simple theoretical model was derived, describing mechanisms of irreversible entropy generation and production of acoustic power in such engines. This model captures the essence in the differences between regular and phase-exchange thermoacoustic engines, and shows good agreement with experimental results of stability limit. Steady state results reveal not only a dramatic decrease in temperature difference, but also an increase in engine performances.

    Full Text Available With the arrival of the sixteenth century, a new stage of prosperity begins in Cartagena and Alicante, supported by the intense mercantile activity generated by its ports. This economic energy served to revitalise a previously dormant space: the Spanish southeast. Taking as a starting point the harbour of Cartagena, this article analyses the enormous magnitude of commercial relationships, the goods exchanged, their production and commercialisation, the behaviour of the mercantile bourgeoisie and the effects of exorbitant taxation that stimulated smuggling and was ultimately responsible for the later stagnation of Cartagena. Through extensive archival work at the municipal archives of Cartagena and Murcia, the Archivo Histórico Provincial (Murcia, the Real Chancillería (Granada, the Archivo Histórico Nacional (Madrid, the Archivo General (Simancas, the Archivio di Stato (Genova, and the Archives Nationales (Paris, the article attempts to fill a historical lacuna. This lacuna has hitherto prevented a full appreciation of the economic environment of Habsburg Spain.

    Full Text Available With the growing mobility of international students in Asia and the Pacific, Taiwan has become actively involved in promoting international academic exchange. This research investigates the experience of exchange students from the Philippines and mainland China and examines their needs while studying in Taiwan. Qualitative in-depth interviews were conducted with exchange students from the Philippines and mainland China. The findings suggest that while exchange students from the Philippines and mainland China both encountered difficulties during their study in Taiwan, exchange students from the Philippines were inclined to encounter more difficulties compared to those from mainland China due to language difficulties. Based on the findings of this study, suggested support services for future exchange students in Taiwan are outlined to match the needs of students from both Chinese and non-Chinese-speaking backgrounds.

    2018-01-01

    Full Text Available Heat exchanger networks have been known to be the essential parts in the chemical industries. Unfortunately, since the performance of heat exchanger can be decreasing in transferring the heat from hot stream into cold stream due to fouling, then cleaning the heat exchanger is needed to restore its initial performance periodically. A process of heating crude oil in a refinery plant was used as a case study. As many as eleven heat exchangers were used to heat crude oil before it was heated by a furnace to the temperature required to the crude unit distillation column. The purpose of this study is to determine the cleaning schedule of heat exchanger on the heat exchanger networks due to the decrease of the overall heat transfer coefficient by various percentage of the design value. A close study on the process of heat exchanger cleaning schedule in heat exchanger networks using the method of decreasing overall heat transfer coefficient as target. The result showed that the higher the fouling value the more often the heat exchanger is cleaned because the overall heat transfer coefficient decreases quickly.

    2011-03-01

    We argue for clear separation of the exchange problem from the exchange paradox to avoid confusion about the subject matter of these two distinct problems. The exchange problem in its current format belongs to the domain of optimal decision making—it doesn't make any sense as a game of competition. But it takes just a tiny modification in the statement of the problem to breathe new life into it and make it a practicable and meaningful game of competition. In this paper, we offer an explanation for paradoxical priors and discuss adaptive strategies for both the house and the player in the restated exchange problem.

    In this article we will focus on forward and futures contracts for managing foreign exchange risk. A forward is a contract to buy or sell currency at an agreed upon exchange rate at a specific date in the future. Futures are similar to forwards except that they’re traded on exchanges which specify settlement dates. Also we make some recommendations related to the foreign exchange risk-management practices that are useful for companies involved in international trade and for financial institutions interested in providing hedging products to these companies.

  11. Essential Specification Elements for Heat Exchanger Replacement

    Energy Technology Data Exchange (ETDEWEB)

    Bower, L.

    2015-07-01

    Performance upgrade and equipment degradation are the primary impetuses for a nuclear power plant to engage in the large capital cost project of heat exchanger replacement. Along with attention to these issues, consideration of heat exchanger Codes and Standards, material improvements, thermal redesign, and configuration are essential for developing User’s Design Specifications for successful replacement projects. The User’s Design Specification is the central document in procuring ASME heat exchangers. Properly stated objectives for the heat exchanger replacement are essential for obtaining the materials, configurations and thermal designs best suited for the nuclear power plant. Additionally, the code of construction required and the applied manufacturing standard (TEMA or HEI) affects how the heat exchanger may be designed or configured to meet the replacement goals. Knowledge of how Codes and Standards affect design and configuration details will aid in writing the User’s Design Specification. Joseph Oat Corporation has designed and fabricated many replacement heat exchangers for the nuclear power industry. These heat exchangers have been constructed per ASME Section III to various Code-Years or ASME Section VIII-1 to the current Code-Year also in accordance with TEMA and HEI. These heat exchangers have been a range of like-for-like replacement to complete thermal, material and configuration redesigns. Several examples of these heat exchangers with their Code, Standard and specification implications are presented. (Author.

    We have measured the vector and tensor polarization of an atomic deuterium target as a function of the target density. The polarized deuterium was produced in an atomic beam source and injected into a storage cell. For this experiment, the atomic beam source was operated without rf transitions, in order to avoid complications from the unknown efficiency of these transitions. In this mode, the atomic beam is vector and tensor polarized and both polarizations can be measured simultaneously. We used a 1.2-cm-diam and 27-cm-long storage cell, which yielded an average target density between 3 and 9x10 11 at/cm 3 . We find that the tensor polarization decreases with increasing target density while the vector polarization remains constant. The data are in quantitative agreement with the calculated effect of spin exchange between deuterium atoms at low field

    What is color? What is light? How can we use a spectrometer to help students understand the answers to these questions? Even half a world apart and between people of different languages and cultures, how to teach these ideas to students can be a lively subject for discussion. And it is! Aided by Internet 2-based videoconferencing, NOAO North and South have sponsored three teacher professional development videoconference workshops, dubbed ASTRO-Chile, linking teachers in Tucson, AZ, and La Serena, Chile. The teachers exchange methods and ideas about how to explain and demonstrate physical concepts, important to the study of astronomy, to students of various ages. The workshops are conducted in Spanish with four bilingual science teachers from the Tucson area discussing pedagogical approaches with their teaching counterparts in Chile. Demonstrations and project presentations, from both sites, are included as part of each workshop. This work is supported, in part, through funding from the NSF Astronomy and Astrophysics Postdoctoral Fellowship.

    Public-key cryptography is too slow for general purpose encryption, with most applications limiting its use as much as possible. Some secure protocols, especially those that enable forward secrecy, make a much heavier use of public-key cryptography, increasing the demand for lightweight cryptosystems that can be implemented in low powered or mobile devices. This performance requirements are even more significant in critical infrastructure and emergency scenarios where peer-to-peer networks are deployed for increased availability and resiliency. We benchmark several public-key key-exchange algorithms, determining those that are better for the requirements of critical infrastructure and emergency applications and propose a security framework based on these algorithms and study its application to decentralized node or sensor networks.

    Julien, Benoît; Kennes, John; King, Ian

    This paper analyzes monetary exchange in a search model allowing for multilateral matches to be formed, according to a standard urn-ballprocess. We consider three physical environments: indivisible goods and money, divisible goods and indivisible money, and divisible goods and money. We compare....... In particular, surplus maximization can be achieved in this setting, in equilibrium, with a positive money supply. Moreover, with flexible prices and directed search, the first best allocation can be attained through price posting or through auctions with lotteries, but not through auctions without lotteries....... Finally, analysis of the case of divisible goods and money can be performed without the assumption of large families (as in Shi (1997)) or the day and night structure of Lagos and Wright (2005)....

    1996-02-01

    Full Text Available In the sixteenth century, there were numerous voyages of discovery in the oceans of the world, expanding European understanding and influence. These explorations, and in particular the knowledge they created, have tended to overshadow other ventures into the unknown. Not just the Europeans, but other cultures as well, navigated the seas and accumulated geographical information, putting together their own ideas about the distribution of the lands and seas around the globe. Arab and Asian seafarers plied the oceans in trade and exploration, and created maps and geographical texts. These maps and texts, however, are not as numerous as a scholar might wish. The Asian maps, particularly early ones, are few in number, and these are virtually all Chinese and Korean creations, world maps based on traditional religious concepts of a circular landmass. There are few maps based on actual navigation. But an early sixteenth-century Portuguese document gives a brief description of a Javanese map, which apparently showed much of the world. It also depicted the routes of the navigations of the Chinese and other Pacific peoples. The map itself has been lost, but we read of it in a letter from the Portuguese admiral Afonso de Albuquerque to his king, Dom Manuel, dated 1 April 1512.No século XVI, várias viagens de descobrimento expandiram a influência e o reconhecimento europeus. Essas expedições marítimas, e em particular o conhecimento que geraram, ofuscaram outras aventuras pelo desconhecido. Outros povos navegaram pelos oceanos, acumularam informações e organizaram suas próprias idéias sobre a distribuição de terras e mares. Navegadores árabes e asiáticos criaram mapas, cartas náuticas e textos geográficos expondo suas descobertas. Esses mapas, no entanto, não são tão numerosos. Os asiáticos, particularmente os mais antigos, são poucos e quase todos originários da China e Coréia, e baseavam-se em conceitos religiosos tradicionais e na id

    Full Text Available En este trabajo analizaremos la relación que se dio entre la Iglesia y la Monarquía de España a través de algunos de los discursos que fundaron su edificio historiográfico. En especial, haremos hincapié en la forma en que se representó al príncipe y a la monarquía hacia mediados del siglo XVI. Así, sin dejar de hacer referencia al contexto cultural y político de la época, indagaremos sobre aquellas características que dotaban al soberano y su gobierno de cualidades que daban a su accionar una legitimidad real para intervenir en el gobierno eclesiástico. Para que esto fuera posible, era necesario dotar a España de una identidad. Al igual que otras monarquías europeas, veremos cómo desde el plano discursivo se fundamentó en los modelos históricos de las monarquías antiguas. In this paper we will analyze the relationships between the Church and the Monarchy of Spain through some of the discourses that founded its historiographic building. In particular, we will highlight how they represented the prince and the monarchy in mid sixteenth century. Thus, we will focus on those characteristics that endow the sovereign and his government with qualities that gave his actions a real legitimacy to intervene in ecclesiastical government without disregarding the cultural and politica context of the time. In order to obtain this legitimacy, it was necessary to provide Spain with an identity. Like other European monarchies, we will see how these discourses were founded on the historical patterns of ancient monarchies.

    2001-12-01

    Full Text Available This article shows some historiographical questions related to the classic work from Ferdinand Braudel's La Méditerranée. At the same time, it takes into account the important bibliography about captives and renegades. It is important to point out that captives and renegades had a key role in the social, political and cultural developments in the Mediterranean Early Modem World. As a sequence the braudelian tradition and the renewal of the historiography on the topic must follow the same path.

    Este artículo muestra que existen cuestiones historiográficas que tienen como marco geográfico y cronológico La Méditerranée de Femand Braudel, pero que dichos temas no se extinguen con su obra. A partir de los años ochenta una importante bibliografía de cautivos y renegados ha pretendido ahondar en la historia de este olvidado colectivo siguiendo las pautas y métodos de Braudel. Arrinconar estos estudios en los balances historiográficos generales sobre el Mediterráneo de los siglos XVI y XVII, o en críticas a Braudel que señalan más sus errores que aciertos, sin duda no hace justicia a este historiador ni a los resultados obtenidos por la historiografía mencionada. Aquí vamos a resaltar algunos de sus logros, pero también sus limitaciones.

    Valenzuela Márquez, Jaime

    2010-12-01

    Full Text Available Beginning with the 16th century conquering expeditions, many Andean natives who served the Spaniards arrived in Chile, where they settled in and integrated in the work and social areas of this outlying «New World»; they formed local networks and relationships, had offspring; a number of them became artisans and some drafted wills or left their mark in ecclesiastical or notarized documents that provide us with an idea of their mobility and local integration. This work offers a background and reveals the principle hubs of a process resembling a medullar structure, in order to understand how the early Chilean colonial society was made up. At the same time, it provides insights into the phenomena of movement, uprooting and settlement of the indigenous population in the southern Peruvian viceroyalty.

    Desde las expediciones de conquista del siglo XVI llegaron a Chile numerosos indígenas andinos que sirvieron a los españoles, se asentaron y se integraron en los espacios laborales y sociales de este «nuevo mundo» periférico; formaron redes y parentescos locales, tuvieron descendencia, varios se transformaron en artesanos y algunos dictaron testamentos o dejaron huellas en documentos eclesiásticos y notariales que nos permiten observar su movilidad e inserción local. Este trabajo aporta antecedentes y desvela los principales ejes de un proceso que aparece como medular para entender la formación de la sociedad colonial chilena temprana y, a la vez, para dar cuenta de fenómenos de circulación, desarraigo y asentamiento de población indígena en el virreinato peruano meridional.

    Full Text Available En la España de la primera mitad del siglo XVI subsisten instituciones y relaciones de poder heredadas de la Edad Media. En el ámbito local éstas pueden rastrearse de manera más clara y concisa, sobre todo cuando se trata de lugares sometidos a un régimen señorial nobiliario o eclesiástico. El caso de Talavera de la Reina (Toledo, responde al segundo modelo; propiedad de los arzobispos toledanos desde 1369, cuando Enrique II le concede la villa y su tierra a Gómez Manrique, que entonces ostentaba la mitra en la archidiócesis, Talavera pretenderá a lo largo de tiempo conservar y defender sus privilegios y costumbres forjadas en la etapa en que fuera villa de realengo.During the first half of the Sixteenth Century there existed institutions and power relations in Spain that had been originated in the Middle Age. These institutions can be well documented at a local level, especially in places under manorial dominion. The case of Talavera de la Reina, In Toledo, constltutes a good example to study the expressions and the symbols of power implemented by the town council to maintain its old privileges and customs of its royal jurisdictional past, glven that it fell under ecclesiastical dominión in 1369. This Study shows expressions and formulas of a feudal nature —such as homage— exhibited by those in power in the Early Modern period.

    Diago Hernando, Máximo

    2010-12-01

    Full Text Available Portuguese Conversos, many of them descendants of the Castilian Jews that were expelled in 1492, played a very important role in the export trade of the Crown of Castile during the 17th century. Among their multiple activities, the export of Castilian wool to France, the Low Countries and other European regions, was a prominent one. In this article the author contributes to the reconstruction of the first phase of the process of involvement of these merchants in this business, from the last decades of the 16th century onwards, after the merchants of Burgos abandoned it. He adopts a limited geographical perspective, because he circumscribes his analysis to a single region, that of Soria and its surroundings.

    Los judeoconversos portugueses, muchos de ellos descendientes de judíos castellanos expulsados en 1492, desempeñaron un destacado papel en el comercio exterior de la Corona de Castilla durante el siglo xvii. Entre sus múltiples actividades estuvo la de exportación de lana fina castellana a Francia, los Países Bajos y otros territorios europeos. En el presente trabajo el autor contribuye a la reconstrucción de la primera fase de participación de estos mercaderes en dicho negocio, a partir de las últimas décadas del siglo xvi, tras el abandono de la actividad por los mercaderes burgaleses. Y lo hace desde una perspectiva geográfica limitada, centrando el análisis en una región en concreto, la de la Tierra de Soria y su entorno.

    Full Text Available Las características biogeográficas de la América templada favorecieron la introducción y propagación de especies animales y vegetales que sustentaron al modelo agroganadero hispano-mediterráneo. Los efectos de este fenómeno generaron alteraciones ecológicas, especialmente en los territorios habitados por aborígenes carentes de actividades productivas intensivas, como fue el caso de la Araucanía. Mediante un análisis histórico documental, la presente investigación reconoció las principales características del proceso de alteración del paisaje ecológico araucano entre los siglos XVI y XVII: (i en el siglo XVI, la introducción de especies exóticas desarticuló el sistema económico mapuche, (ii tanto la relativa pristinidad de la Araucanía como el proceso bélico de los siglos XVI y XVII, favorecieron la introducción y propagación de las nuevas especies, (iii durante el siglo XVI coexistieron especies nativas e introducidas, sin embargo, durante el siglo XVII preponderaron las exóticas, y (iv este predominio habría generado la extinción local de especies animales y vegetales nativas, alterando definitivamente el paisaje ecológico araucanoThe bio-geographic characteristics of the temperate America favored the introduction and spreading of exotic plant and animal species that supported the Hispanic-Mediterranean farming model. The effects of this situation produced ecological alterations on the territories inhabited by Indians without intense productive systems; as the Araucanía case. Through a historical and documental analysis this paper reports the main characteristics of the Araucanian ecological landscape disruption process during the 16th and 17th centuries: (i during the 16th century, the introduction of exotic species dislocated the Mapuche economic system, (ii both the relative Araucanía pristine conditions and the warlike process, occurred between the 16th and 17th centuries, favored the introduction and

    2013-06-01

    We present the first in vivo application of the filter-exchange imaging protocol for diffusion MRI. The protocol allows noninvasive mapping of the rate of water exchange between microenvironments with different self-diffusivities, such as the intracellular and extracellular spaces in tissue. Since diffusional water exchange across the cell membrane is a fundamental process in human physiology and pathophysiology, clinically feasible and noninvasive imaging of the water exchange rate would offer new means to diagnose disease and monitor treatment response in conditions such as cancer and edema. The in vivo use of filter-exchange imaging was demonstrated by studying the brain of five healthy volunteers and one intracranial tumor (meningioma). Apparent exchange rates in white matter range from 0.8±0.08 s(-1) in the internal capsule, to 1.6±0.11 s(-1) for frontal white matter, indicating that low values are associated with high myelination. Solid tumor displayed values of up to 2.9±0.8 s(-1). In white matter, the apparent exchange rate values suggest intra-axonal exchange times in the order of seconds, confirming the slow exchange assumption in the analysis of diffusion MRI data. We propose that filter-exchange imaging could be used clinically to map the water exchange rate in pathologies. Filter-exchange imaging may also be valuable for evaluating novel therapies targeting the function of aquaporins. Copyright © 2012 Wiley Periodicals, Inc.

  4. The hydrogen-deuterium exchange of macromolecules

    International Nuclear Information System (INIS)

    Duane, C.J.

    1982-06-01

    An infra red spectroscopic technique has been developed which allows the hydrogen-deuterium exchange between a polymer and absorbed heavy water to be monitored with the polymer in contact with liquid heavy water. This method extends the existing methods to the highest possible internal water concentration. The results of Moore on the hydrogen-deuterium exchange of poly(N-t-butylacrylamide) have been extended to the lower homologues of the series. The rate and extent of the exchange of these polymers is dependent upon the pH of the conditioning solution in which the polymer is exposed prior to the exchange study. The exchange is acid and base catalysed with the latter only apparent in the lower homologues. The features of the acid catalysed exchange have been tentatively explained in terms of the mobility of the hydrogen ion in the polymer matrix, whilst the restricted base exchange is attributed to the lack of hydration stabilisation of the intermediate ion complex of the base catalysed mechanism. The hydrogen-deuterium exchange properties of nylon, silk and cellulose have also been studied and these polymers show far less sensitivity to the pH of the conditioning treatment. The results are discussed. (author)

    2011-11-01

    To determine the proportion of US hospitals engaged in health information exchange (HIE) with unaffiliated providers and to identify key hospital-level and market-level factors associated with participating in exchange. Using the 2009 American Hospital Association Information Technology survey, supplemented by Dartmouth Atlas, Area Resource File, and other national data, we examined which hospitals participated in regional efforts to electronically exchange clinical data. We used logistic regression models to determine hospital-level characteristics and market-level characteristics associated with hospitals' likelihood of participating in HIE. We found that 10.7% of US hospitals engaged in HIE with unaffiliated providers. In communities where exchange occurred, for-profit hospitals and those with a small market share were far less likely to engage in HIE than nonprofit hospitals or those with a larger market share. Hospitals in more concentrated markets were more likely to exchange and hospitals in markets with higher Medicare spending were less likely to exchange. At the start of implementation of the Health Information Technology for Economic and Clinical Health (HITECH) Act, only a small minority of US hospitals electronically exchange clinical data with unaffiliated providers. Health information exchange is a key part of reforming the healthcare system, and factors related to competitiveness may be holding some providers back.

    Sebesta, F.; John, J.; Motl, A.

    1998-01-01

    Composite inorganic ion exchangers are described containing modified polyacrylonitrile as the binding polymer. An overview of existing composite ion exchangers is presented, and the universality and assets of the developed procedure of treatment of inorganic ion exchanger powders are highlighted. Examples of applicability of the ion exchangers to the separation and concentration of radionuclides include in particular: wastes from the operation of nuclear power plants, contaminated surface waters and ground water, high level radioactive wastes from spent fuel reprocessing, and wastewaters from uranium ore mining and milling. In addition, composite ion exchangers find use in the monitoring of contamination of the hydrosphere and the environment and in the investigation of radionuclide migration in surface waters and ground water

  20. Ion-exchange properties of natural mordenite

    International Nuclear Information System (INIS)

    Chelishchev, N.F.; Volodin, V.F.

    1977-01-01

    Ion exchange properties are studied of natural mordenite Si(Al=4.75) exhibiting adequate mechanical characteristics and sufficient resistance to high temperature acids. Consideration is given to the pattern of exchange ions distribution among mordenite and chloride solutions of K, Cs, Rb, Sr. Mordenite shows sharp selectivity towards large alkali metal cations, particularly Cs + . In these processes the exchange isotherms are characterized by the constant selectivity towards a counterion. For the Sr 2+ -2Na + exchange the isotherm shows a change of selectivity after a definite counterion concentration has been reached in the solution. Correlation between the exchange thermodynamic constants makes it possible to propose the following range of mordenite selectivity towards the cations under study: Cs>Rb>K>Na>Sr

    The isotopic exchange approach is in use since the first observation of such reactions in 1933 by Lewis. This approach allows the investigation of the pathways of chemical and biochemical reactions, determination of structure, composition, and conformation of molecules. Mass spectrometry has now become one of the most important analytical tools for the monitoring of the isotopic exchange reactions. Investigation of conformational dynamics of proteins, quantitative measurements, obtaining chemical, and structural information about individual compounds of the complex natural mixtures are mainly based on the use of isotope exchange in combination with high resolution mass spectrometry. The most important reaction is the Hydrogen/Deuterium exchange, which is mainly performed in the solution. Recently we have developed the approach allowing performing of the Hydrogen/Deuterium reaction on-line directly in the ionization source under atmospheric pressure. Such approach simplifies the sample preparation and can accelerate the exchange reaction so that certain hydrogens that are considered as non-labile will also participate in the exchange. The use of in-ionization source H/D exchange in modern mass spectrometry for structural elucidation of molecules serves as the basic theme in this review. We will focus on the mechanisms of the isotopic exchange reactions and on the application of in-ESI, in-APCI, and in-APPI source Hydrogen/Deuterium exchange for the investigation of petroleum, natural organic matter, oligosaccharides, and proteins including protein-protein complexes. The simple scenario for adaptation of H/D exchange reactions into mass spectrometric method is also highlighted along with a couple of examples collected from previous studies. © 2018 Wiley Periodicals, Inc.

  8. Longitudinal exchange: an alternative strategy towards quantification of dynamics parameters in ZZ exchange spectroscopy

    International Nuclear Information System (INIS)

    Kloiber, Karin; Spitzer, Romana; Grutsch, Sarina; Kreutz, Christoph; Tollinger, Martin

    2011-01-01

    Longitudinal exchange experiments facilitate the quantification of the rates of interconversion between the exchanging species, along with their longitudinal relaxation rates, by analyzing the time-dependence of direct correlation and exchange cross peaks. Here we present a simple and robust alternative to this strategy, which is based on the combination of two complementary experiments, one with and one without resolving exchange cross peaks. We show that by combining the two data sets systematic errors that are caused by differential line-broadening of the exchanging species are avoided and reliable quantification of kinetic and relaxation parameters in the presence of additional conformational exchange on the ms–μs time scale is possible. The strategy is applied to a bistable DNA oligomer that displays different line-broadening in the two exchanging species.

  9. Biodegradation of ion-exchange media

    International Nuclear Information System (INIS)

    Bowerman, B.S.; Clinton, J.H.; Cowdery, S.R.

    1988-08-01

    Ion-exchange media, both bead resins and powdered filter media, are used in nuclear power plants to remove radioactivity from process water prior to reuse or environmental discharge. Since the ion- exchange media are made from synthetic hydrocarbon-based polymers, they may be susceptible to damage from biological activity. The purpose of this study was to investigate some of the more basic aspects of biodegradation of ion-exchange media, specifically to evaluate the ability of microorganisms to utilize the ion-exchange media or materials sorbed on them as a food source. The ASTM-G22 test, alone and combined with the Bartha Pramer respirometric method, failed to indicate the biodegradability of the ion-exchange media. The limitation of these methods was that they used a single test organism. In later phases of this study, a mixed microbial culture was grown from resin waste samples obtained from the BNL High Flux Beam Reactor. These microorganisms were used to evaluate the susceptibility of different types of ion-exchange media to biological attack. Qualitative assessments of biodegradability were based on visual observations of culture growths. Greater susceptibility was associated with increased turbidity in solution indicative of bacterial growth, and more luxuriant fungal mycelial growth in solution or directly on the ion-exchange resin beads. 21 refs., 9 figs., 18 tabs

  10. Ion exchange fiber by radiation grafting, 1

    International Nuclear Information System (INIS)

    Fujiwara, Kunio

    1990-01-01

    Radiation grafting is gaining attention as a method for producing high performance materials. This method can be applied to add functions to existing polymer plastics. The author participated in the research program on the production of ion exchange fiber by radiation grafting and its applicability at the Japan Atomic Energy Research Institute, Takasaki Radiation Chemistry Research Establishment. Consequently, it was clarified that it was possible to introduce the cation exchange group, represented by sulfonic and carboxyl groups, and the anion exchange group, represented by the quarternary ammonium group, to polypropylene fiber available on the market. The ion exchange capacity was able to be controlled by the degree of grafting, i.e. approximately up to 3 meq/g in both strong acid and strong base and approximately up to 5 meq/g in weak acid were obtained. The adsorption performance of ammonia, a representative malodorous substance, was also studied using test cation exchange fiber. The adsorption rate of H type strong acid cation exchange fiber was great, due to the H type having neutral reaction, and the adsorption capacity matched the ion exchange capacity. Although the Cu and Ni types features coordinated adsorption and their adsorption rates were from 1/2 to 1/3 of that of the H type, their adsorption capacities showed increase along with the metal adsorbed.

  12. Searching for an Appropriate Exchange Rate Regime

    Directory of Open Access Journals (Sweden)

    Yunjong Wang

    2001-06-01

    Full Text Available This paper attempts to survey current debates on the choice of exchange rate regime in emerging market economies. The issue of choosing an appropriate exchange rate regime is being actively discussed since the recent Asian crisis. As a lesson from the recent crises, one widely shared conclusion is that soft peg exchange rate regimes are extremely vulnerable in a world of volatile capital movements. Consequently, new orthodoxy based on the impossible trinity hypothesis favours two corner solutions ― greater flexibility or credible institutional assurance, like a currency board system or dollarization. Nevertheless, questions whether such corner solutions are adequate for developing countries are rising of late. "Fear of floating" is still conspicuous in many developing countries having adopted nominally a free-floating exchange rate regime. Developing countries are sensitive to exchange rate fluctuations because the cost of exchange rate volatility is greater than the benefit when compared to developed countries. Monitoring bands is a compromise solution, but it still needs further enhancement of estimation techniques for fundamental equilibrium exchange rates in order to make those estimation results more workable in practice. Other alternatives include the creation of soft peg of the G-3 currencies. Despite counterarguments, the stability of G-3 currencies could prove to be beneficial to emerging market economies.

  13. Ion Exchange Formation via Sulfonated Bicomponent Nonwovens

    Science.gov (United States)

    Stoughton, Hannah L.

    For many years ion exchange resins were used to: remove heavy metals from water, recover materials from wastewater, and eliminate harmful gases from the air. While use of these resin beads dominates the ion exchange industry, the beads have limitations that should be considered when decisions are made to employ them. For instance, officials must balance the inherent zero sum surface area and porosity of the materials. This series of studies investigates the use of bicomponent nonwovens as a base substrate for producing high surface area ion exchange materials for the removal of heavy metal ions. Functionalized materials were produced in a two-step process: (1) PET/PE spunbond bicomponent fibers were fractured completely, producing the high surface area nonwoven to be used as the base ion exchange material, and (2) the conditions for functionalizing the PET fibers of the nonwoven webs were investigated where an epoxy containing monomer was grafted to the surface followed by sulfonation of the monomer. The functionalization reactions of the PET fibers were monitored based on: weight gain, FTIR, TOF-SIMS, and SEM. Ion exchange properties were evaluated using titration and copper ion removal capacity from test solutions. The relationship between web structure and removal efficiency of the metal ions was defined through a comparison of the bicomponent and homocomponent nonwovens for copper ion removal efficiency. The investigation revealed that utilizing the high surface area, fractured bicomponent nonwoven ion exchange materials with capacities comparable to commercially available ion exchange resins could be produced.

    One point investigated in our research project on the linguistic experiences of exchange students in Denmark and Sweden is the reasons students have for coming on exchange. Traditionally, an important goal of student exchange was to acquire improved language skills usually in the language spoken...... in the host country. To what extent is this true when students plan to study in English in a non-English speaking country? Do they hope and expect to improve their English skills, their knowledge of the local language, both, or neither? to what extent are these expectations fulfilled? Results form the project...

    Konuk, A.A.

    1981-01-01

    Differential equations describing the heat tranfer in shell - and tube heat exchangers are derived and solved numerically. The method of ΔT sub(lm) is compared with the proposed method in cases where the specific heat at constant pressure, Cp and the overall heat transfer coefficient, U, vary with temperature. The error of the method of ΔT sub (lm) for the computation of the exchanger lenght is less than + 10%. However, the numerical method, being more accurate and at the same time easy to use and economical, is recommended for the design of shell-and-tube heat exchangers. (Author) [pt

    1985-08-01

    Concepts are described for regeneration of the intermediate liquid used for isotope exchange in indirect laser isotope separation processes where the laser operates on a process gas distinct from the feed stream. The specific case of regeneration of an exchange liquid consisting of water, sodium hydroxide, and dimethyl sulfoxide for a process to separate deuterium from hydrogen using laser irradiation of trifluoromethane gas is developed. A water feed stream is converted to steam which rises in a chemical process column where it redeuterates a descending flow of exchange liquid without causing significant changes in its chemical composition

    2010-12-28

    A skewed chicane eigenmode exchange module (SCEEM) that combines in a single beamline segment the separate functionalities of a skew quad eigenmode exchange module and a magnetic chicane. This module allows the exchange of independent betatron eigenmodes, alters electron beam orbit geometry, and provides longitudinal parameter control with dispersion management in a single beamline segment with stable betatron behavior. It thus reduces the spatial requirements for multiple beam dynamic functions, reduces required component counts and thus reduces costs, and allows the use of more compact accelerator configurations than prior art design methods.
