    The aim of our studies was to determine the usefulness of various imaging techniques for localization of thyroid ectopia in patients with congenital hypothyroidism (CH). 50 patients with CH were observed. In each case the following studies were performed: serum thyroglobulin level, thyroid radioiodine uptake, scintigraphy using {sup 99m}Tc and {sup 131}I and ultrasonography. Among 50 patients with CH were found: 18 cases (36%) of thyroid agenesis, 7 cases (14%) of thyroid hypoplasia and 25 patients (50%) with lingual thyroid ectopia. Thyroid radioiodine uptake in patients with thyroid ectopia ranged from 2% to 18%, serum thyroglobulin level was from 0.7 ng/ml to 12.8 ng/ml (mean value 6.6 ng/ml). Ultrasonography showed an absence of thyroid gland at its normal site, but its presence in the tongue. Lingual thyroid ectopia was oval or round, and its volume ranged from 0.17 to 1.38 cm{sup 3}. The use of scintigraphy with {sup 99m}Tc loads to its accumulation in the submaxillary salivary glands what can make difficult to detect thyroid ectopia. Scintigraphy of the neck and retrosternal area has not shown any thyroid tissue, but there were the accumulation of {sup 131}I in thyroid gland in the sublingual area. Conclusions: 1. Thyroid ectopia is a frequent cause of congenital hypothyroidism (in about 50% of all thyroid gland development abnormalities); 2. to detect lingual thyroid ectopia the best method is scintigraphy with {sup 131}I and ultrasonography.

    Full Text Available Aim. The aim of this study was to show the influence of schizophrenia on the individual system of meanings – the way in which the persons describe themselves and their life story. In order to achieve this goal, the analysis of narration of patients suffering from schizophrenia was conducted. Method. We examined 20 patients suffering from schizophrenia. We interviewed the patients with a structured narrative questionnaire. The persons described their life and themselves - in the time before and after the psychotic crisis. The interviews were analysed according to different literary methods and the knowledge of formal linguistics. The demographic variables and the clinical state of patients were also controlled. Results. Persons suffering from schizophrenia used more positive attributes and less negative attributes while describing themselves before illness. They reported more positive episodes from their life, before the psychotic crisis. Conclusions. The psychotic crisis causes the dramatic decrease of self esteem and breakdown of the life story. The patients described themselves and their life in negative, pessimistic optics. The trauma of mental illness is reflected in narration by breakdown of “good story” about the person and her/his life. This change of self image concerns the persons who both cooperate in psychotherapy and are critical to illness.

    Full Text Available Aim. Planning disorders have been observed in people with frontal lobe lesions for many decades. There’s also growing body of evidence of frontal dysfunction in people with schizophrenia. The aim of this study is to compare the planning abilities in men with schizophrenia, men with localized frontal lobe lesions and healthy men.Method. A sample of 90 men participated in the study. They were divided into three groups: men with schizophrenia (n=30, men with localized frontal lobe lesions (n=30 and healthy men (n=30 as a control group. Planning abilities were assessed with a clinical trialbased on Tower of London task. Results. Significant differences in ToL measures were found between controls and men with schizophrenia (Trials solved: p<0.01; Trials solved perfectly: p<0.05; Execution time: p<0.001 and between controls and men with frontal lobe lesions (Trials solved: p<0.001;Thinking time: p<0.05; Execution time: p<0.001. No significant differences were found between schizophrenia and frontal lobe lesion groups.Conclusions. Similar deficits in planning and solving problems, which require planning, may be observed in men with schizophrenia and men with frontal lobe lesions. In both groups time spent on thinking is less effective than in healthy men. Not only quantitative, but also qualitative assessment should be carried when examining patients’ performance on Tower of London task.

NA49 is one of the seven experiments (NA44, NA45, NA49, NA50, NA52, WA97/NA57 and WA98) involved in CERN's Heavy Ion programme which provided evidence for the existence of a new state of matte, the quark-gluon plasma. In this state, quarks, instead of being bound up into more complex particles such as protons and neutrons, are liberated and roam freely. Theory predicts that this state must have existed at about 10 microseconds after the Big Bang, before the formation of matter as we know it today.

    NA60 measured dimuon production in p-A and In-In collisions at the CERN SPS. This paper presents a high statistics measurement of $\\phi$ meson production in In-In collisions at 158 AGeV. Both the transverse momentum, rapidity, decay angular distributions and the absolute yield were measured as a function of centrality. The results are compared to previous measurements in order to shed light on the long standing $\\phi$ puzzle. In addition, highlights on $\\eta$ meson production and on the dimuon excess below the J/$\\psi$ mass are presented.

  1. Measurement of exchangeable sodium: 22Na or 24Na

    International Nuclear Information System (INIS)

    A case is made for the use of 22Na in low activities in preference to 24Na for routine diagnostic estimation of exchangeable sodium, and is based chiefly on considerations of availability, cost and radiation dosimetry. A method in which only 37 kBq (1 μCi) 22Na is administered orally is shown to be sufficiently accurate and to possess distinct advantages in terms of cost and convenience with a committed radiation dose no greater than that for a measurement using 24Na.

    Quando viam um cometa, os antigos gregos imaginavam uma estrela com uma vasta cabeleira. Não à toa, a palavra deriva do termo koma, que significa cabelo. Constituídos por fragmentos de gelo e gases, os cometas possuem um núcleo sólido, que pode ter vários quilômetros de diâmetro, e uma cauda que sempre aponta na direção contrária ao Sol, devido aos ventos solares. Graças à aparência de pontos luminosos em movimento (ao contrário de outros astros, que parecem estáticos), esses corpos celestes foram interpretados por diferentes povos com muito misticismo, inspirando mitos tanto de boas-novas como de maus presságios. Conheça algumas dessas histórias:

  6. NA48 prototype calorimeter

    CERN Multimedia

    1990-01-01

    This is a calorimeter, a detector which measures the energy of particles. When in use, it is filled with liquid krypton at -152°C. Electrons and photons passing through interact with the krypton, creating a shower of charged particles which are collected on the copper ribbons. The ribbons are aligned to an accuracy of a tenth of a millimetre. The folding at each end allows them to be kept absolutely flat. Each shower of particles also creates a signal in scintillating material embedded in the support disks. These flashes of light are transmitted to electronics by the optical fibres along the side of the detector. They give the time at which the interaction occurred. The photo shows the calorimeter at NA48, a CERN experiment which is trying to understand the lack of anti-matter in the Universe today.

  8. Investigation on U - O - Na, Pu - O - Na and U,Pu - O - Na phase diagrams

    International Nuclear Information System (INIS)

    The thermochemical interaction between the nuclear fuel (uranium and plutonium mixed oxides) and the sodium has been investigated and particularly the three phase diagrams: U - O - Na; Pu - O - Na; U,Pu - O - Na. High temperature neutron diffraction, microcalorimetry and powder X-ray diffraction were used for the characterization of the compounds synthetized. This study allowed to complete the knowledge about each of these diagrams and to measure some physical and thermal properties on the compounds. The limits on the modelization of the fuel-sodium interaction are discussed from the results of the UO2 - Na reaction

  9. Energy levels of 24Na

    International Nuclear Information System (INIS)

    Four experiments are reported yielding excitation energies, spins, parities, mean lifetimes, γ-ray branching ratios of 24Na. The applied methods include particle-γ angular correlations and Doppler shift attenuation method lifetime measurements. From a 23Na(d,pγ)24Na experiments using a large Ge(Li) γ-detector excitation energies, branching ratios and mean lifetimes are determined. A 26Mg(d,αγ)24Na experiment using a NaI(Te) γ-detector enables the assignment of spins and γ-ray mixing ratios. From a 22Ne(3He,pγ)24Na measurement with a deeply implanted 22Ne target, preliminary data from the γ-decay of levels with Ex = 4 - 6 meV and additional nuclear lifetime data are decided. Finally a 23Na(n,γ)24Na γ-spectrum obtained with thermal neutrons and a Ge(Li) detector enabled the adjustment of some of the level energies. The data from these and other experiments were collected and compared with theory. It turned out that the statistical model of nuclear reactions does not give reliable information about nuclear spin-parity combinations. However recent shell-model calculations of Chung give remarkable agreement for low-lying levels (Ex < 3.3 meV)

    Full Text Available Neste texto pretende-se discorrer sobre valores morais na escola e suas implicações para a formação de professores. Para tanto discutir-se-á, em primeiro lugar, e brevemente, o que são valores morais, ou éticos, e como a escola pode situar-se em relação a eles. Em seguida, serão relatadas algumas observações a respeito de valores de professores e práticas daí decorrentes. São comentados resultados de pesquisa que ilustram a transmissão de valores de forma doutrinal e a educação moral e cívica tal como realizada na ditadura militar, e, por outro lado, a posição relativista e/ou de laissez-faire que certas escolas podem adotar, metodologicamente, sobre a educação em valores. Finalmente, defender-se-á a idéia de que é necessária uma discussão sobre valores pelos diversos membros da escola e uma opção por uma metodologia para ensiná-los, seja os professores, em sua formação inicial e continuada, seja os alunos. A teoria de desenvolvimento moral de Jean Piaget será apresentada como uma referência possível para a educação em valores. Exemplos de situações escolares de conflito de valores entre direção, pais e alunos são discutidas para ilustrar como uma escola pode adotar um procedimento democrático de educação em valores, que se apresenta como um terceiro caminho possível de educação moral nas escolas, além das posições doutrinárias ou relativistas.

    Full Text Available Para Hume, filosofar é uma atividade semelhante às demais ocupações humanas. A decisão que leva à atividade filosófica é menos resultado de uma argumentação teórica do que fruto de um cálculo prático, que é entendido como uma caça ou um jogo. O objetivo deste trabalho será o de mostrar que no jogo filosófico perde quem joga sério demais. A aposta na filosofia tem que passar pelo bom humor e pela diversão: uma resposta a Pascal?For Hume, philosophy is in itself neither more nor less important than other human activities. On the contrary, it can be explained from its resemblance with game and hunting. If one chooses to dedicate himself to philosophy, his decision is not the consequence of logical reasoning, but depends on practical evaluation, which has something to do with gambling. The following text tries to show that in philosophy, like in other games, the loser will be the one who plays too earnestly. The philosophical game requires good humour and some relaxation: Is this a good answer to Pascal's pari?

    Full Text Available O momento nazista permanece um enigma impensado de que a cultura contemporânea continua cativa. O autor levanta a hipótese de que a persistência desse enigma e seus estragos duráveis se devem à insistência dos pensamentos político, sociológico e filosófico em construírem o nazismo à luz da metáfora hobbesiana do Leviatã. Propõe retomar a questão do nazismo sob a perspectiva do Behemoth, antônimo do Leviatã. Para tanto, sugere a necessidade de retornar a Freud e à psicanálise, balizas de um possível novo pensamento do político que escrutine a destrutividade nazista. Propõe ainda sondar as homologias entre nazismo, corjas e máfias, com base na figura da " heroicização da violência" que lhes seria comum. E avança um modelo " econômico" : a quimera, suscetível de capturar o caráter heterotópico e heterocrônico de sua construção criminosa.The paths of Behemoth. The Nazi moment remains as the thoughtless enigma of which contemporary culture is still captive. The author raises the hypothesis where the persistency of this enigma and its durable damages are due to the insistence of the political, social and philosophical thoughts in building the Nazism at the view of the Hobbesian metaphor of Leviathan. It is here proposed to resume the Nazism matter under Behemoth's perspective, antonym to Leviathan. For such, it is suggested a necessity to look back at Freud and the psychoanalysis, structured by a possible new political thought which scrutinizes the destructivity of the Nazism. It is also here proposed to gaze at the homologies between Nazism, mafias and gangs, with a base in the figure of " violence as a heroically act" that are their common ground. The author also advances an economical model: the chimera susceptible to capture the heterotopic and heterochronic character of its criminal construction.

    The image shows the new rare Kaon decay experiment at CERN, called NA62. The NA62 experiment is 270 metres long and includes a 120-metre-long vacuum tank, shown here, housing several of the particle detectors. (Note: the experiment axis is a straight line, the curving of the tank is an optical effect of the photo.) Kaons are particles that decay into lighter elementary particles. The kaon decay processes are mostly well known, except for some very rare decay modes. For example, NA62 is investigating a rare decay predicted by the Standard Model in which a kaon decays into one pion and two neutrinos. This process occurs only once every 10 billion decays. The understanding of such ultra-rare decays are of great importance because they test the Standard Model in energy ranges not accessible by direct measurements. They are therefore complementary to the measurements at the LHC. ultra high definition on demand (photolab@cern.ch).

  6. The NA62 trigger system

    International Nuclear Information System (INIS)

    The main aim of the NA62 experiment (NA62 Technical Design Report, 〈http://na62.web.cern.ch/NA62/Documents/TDFulldocv1.pdf〉 [1]) is to study ultra-rare Kaon decays. In order to select rare events over the overwhelming background, central systems with high-performance, high bandwidth, flexibility and configurability are necessary, that minimize dead time while maximizing data collection reliability. The NA62 experiment consists of 12 sub-detector systems and several trigger and control systems, for a total channel count of less than 100,000. The GigaTracKer (GTK) has the largest number of channels (54,000), and the Liquid Krypton (LKr) calorimeter shares with it the largest raw data rate (19 GB/s). The NA62 trigger system works with 3 trigger levels. The first trigger level is based on a hardware central trigger unit, so-called L0 Trigger Processor (L0TP), and Local Trigger Units (LTU), which are all located in the experimental cavern. Other two trigger levels are based on software, and done with a computer farm located on surface. The L0TP receives information from triggering sub-detectors asynchronously via Ethernet; it processes the information, and then transmits a final trigger decision synchronously to each sub-detector through the Trigger and Timing Control (TTC) system. The interface between L0TP and the TTC system, which is used for trigger and clock distribution, is provided by the Local Trigger Unit board (LTU). The LTU can work in two modes: global and stand-alone. In the global mode, the LTU provides an interface between L0TP and TTC system. In the stand-alone mode, the LTU can fully emulate L0TP and so provides an independent way for each sub-detector for testing or calibration purposes. In addition to the emulation functionality, a further functionality is implemented that allows to synchronize the clock of the LTU with the L0TP and the TTC system. For testing and debugging purposes, a Snap Shot Memory (SSM) interface is implemented, that can work

    Full Text Available A inegável atenção dada ao corpo na sociedade inspirou a construção deste trabalho, visto que os imperativos atuais são a beleza, a forma e o vigor. A velhice e a inexorabilidade da morte apresentam-se para este ideal como incômodos que devem ser afastados através de diversos hábitos "saudáveis" e “rejuvenescedores”, como a ginástica, os cosméticos, as vitaminas, procedimentos estético-cirúrgicos, entre outros. O modo de “ser velho”, então, passa a ser configurado não mais por estereótipos negativos, mas a partir de um ethos em que os idosos são apresentados como saudáveis, joviais, engajados, produtivos e autoconfiantes. São corpos que ultrapassam as marcas do tempo, atléticos, firmes e lisos. Logo, aqueles que não aderem a este ethos podem tornar-se desviantes, estranhos, velhos, ultrapassados e precisam, portanto, serem descartados ou escamoteados. Tendo em vista estas questões, o presente trabalho propõe-se a discutir sobre o tema velhice, corpo e sociedade, na tentativa de problematizar sobre os atuais modos de subjetivação e o envelhecimento na contemporaneidade.

  14. Solid state diffusion of NaCl into NaY zeolite studied by positron annihilation

    International Nuclear Information System (INIS)

    A series of samples, prepared from mechanical mixtures of NaCl with NaY zeolite and resulting in the dispersion of NaCl in NaY, was studied by position annihilation spectroscopy. We measured the positron lifetime spectroscopy as a function of the weight ratio of the NaCl-NaY zeolite heated at 500 degree C for 1 h, as a function of the heating temperature held for 1 h, and as a function of the heating duration at 500 degree C for NaCl/NaY (15%). All the lifetime spectra were resolved into five components, in which the third, fourth and fifth components are related to the positron annihilation in β cage, supercage and interface void respectively. The experimental results showed that position annihilation spectroscopy is sensitive to the change of the dispersion of NaCl in NaY zeolite

Análises de aflatoxinas realizadas no Laboratório de Análises Micotoxicológicas (LAMIC da Universidade Fedaral de Santa Maria, entre os anos de 1986 e janeiro de 2000, em 15.600 amostras de alimentos destinados principalmente ao consumo animal, demonstram que no milho analisado, 41,9% das amostras estavam contaminadas por aflatoxinas. Em surtos de aflatoxicose no campo, uma das características mais marcantes é a má absorção que se manifesta como partículas de ração mal digeridas na excreta das aves. Também observa-se, em frangos e poedeiras que recebem AFL, extrema palidez das mucosas e pernas. Dietas deficientes em riboflavina ou colecalciferol (vit.

    International Nuclear Information System (INIS)

    A study of 23Na via the 22Ne(p,γ)23Na and 23Na(γ,γ)23Na reactions is presented. Only a limited number of resonances has been studied, selected on the basis of strong excitation of the lowest levels of which the spin was unknown. As a result the spins are now known of all levels of 23Na with excitation energies up to 7 MeV, except for a few high-spin states which are too weakly excited in the decay of the known 22Ne(p,γ) resonances. The mean lifetimes of the 23Na levels at 4.43 and 7.89 MeV were found to be 350±70 and 220±17 attoseconds (1 attosecond = 10-18 seconds) respectively. 97 refs.; 22 figs.; 12 tabs

  17. Dependence of intracellular Na+ concentration on apical and basolateral membrane Na+ influx in frog skin

    International Nuclear Information System (INIS)

    An isotopic method was developed to measure the intracellular Na+ content of the transepithelial Na+ transport pool of frog skin. Isolated epithelia (no corium) were labeled with 24Na either asymmetrically, from apical (Aa) or basolateral (Ab) solutions, or symmetrically (Aab). Transport pool Na+ could be identified from the kinetics of washout of 24Na carried out in the presence of 1 mM ouabain, 100 microM amiloride, and 1 mM furosemide that served to trap cold Na+ and 24Na within the transport pool. In control epithelia, Aab averaged 64.1 neq/cm2 (13.9 mM), and maximal inhibition of apical membrane Na+ entry with 100 microM amiloride caused Aab to decrease to 24.3 neq/cm2 (5.3 mM). Ouabain caused Aab to increase markedly to 303 neq/cm2 in 30 min, whereas amiloride inhibition of apical membrane Na+ entry reduced markedly the rate of increase of Aab caused by ouabain. These data, in part, confirmed the existence of an important basolateral membrane permeability to Na+ that was measured in separate studies of the bidirectional 24Na fluxes at the basolateral membranes of the cells. Both sets of data were supportive of the idea that a significant Na+ recycling exists at the basolateral membranes of the cells that contributes to the Na+ load on the pump and Na+ recycling participates in the regulation of the Na+ concentration of the Na+ transport pool of these epithelial cells

The dependence of the mutational effects on the specific α isoform in which the mutation is introduced was furthermore studied. At the cellular level we have characterized the C-terminal extension mutants and other mutants......, addressing the question to what extent they cause a change of the intracellular Na+ and K+ concentrations ([Na+]i and [K+]i) in COS cells. C-terminal extension mutants generally showed dramatically reduced Na+ affinity without disturbance of K+ binding, as did other RDP mutants. No phosphorylation from ATP...... was observed for the +28 mutation of α2 despite a high expression level. A significant rise of [Na+]i and reduction of [K+]i was detected in cells expressing mutants with reduced Na+ affinity and did not require a concomitant reduction of the maximal catalytic turnover rate or expression level.

  5. Study of the Na-C-O and Na-H-O ternary systems in the sodium rich corner

    International Nuclear Information System (INIS)

    The purpose of this study is to provide a contribution to the understanding of the sodium - carbon - oxygen and sodium - hydrogen - oxygen ternary systems in the sodium rich corner. In order to do this the Na-NaH-Na2O-NaOH phase diagram was completed and the Na-Na2O-Na2CO3-C phase diagram was outlined. This work is made up of two parts. The first is devoted to a critical literature survey essential to establish correct phase diagrams. The second is an experimental study followed by a discussion collating our finding to the literary data. The basic experimental technique used is differential thermal analysis (DTA) but it has been completed by quenching, X-ray and chemical analysis methods. The proposed phase diagrams imply that Na-NaH-Na2O-NaOH and Na-Na2O-Na2CO3-C systems are reciprocal ternary systems. Temperatures of stable pairs reversal are respectively 410 and 6900C. The stable pairs are Na-NaOH and Na-Na2CO3 at elevated temperature, Na2O-NaH and Na2O-C at low temperature

    Crystals of Na-Pb-O and Na-Pb-Bi-O were electrosynthesized on the anode from molten salts. The resulting crystals have a hexagonal structure, in which the base ions (Pb and Bi) are in high oxidation states. By using KOH/NaOH (atomic ratio K:Na=1:1) mixture as a flux,incorporation of K ions into the lattice is inhibited while incorporation of Bi ions is enhanced. The magnetic measurement shows that the Na-Pb-Bi-O crystals are dominated by diamagnetism.

    2014-07-01

    Full Text Available O bullying é uma forma de violência presente nas escolas e o termo é utilizado para caracterizar todas as formas de agressões repetitivas psicológicas e físicas, direta ou indiretamente. Esta violência causa sofrimentos, intimidação e medo, sempre numa relação de poder entre pares. Esta pesquisa trata de um estudo do bullying escolar: o que é, como surgiu, como identificá-lo e sua caracterização, conseqüências, causas, o papel da escola, de professores e pais e uma proposta prática que pode ser adotada para sua prevenção e contenção. O objetivo é organizar materiais para leitura dos atores educacionais para uma possível reflexão, através de pesquisas bibliográficas. Esta violência é grave e deveria ser tratada como saúde pública, devido às conseqüências que traz, como queda na aprendizagem, na autoestima e em casos mais graves, até o suicido e outras tragédias. A escola necessita atentar para esse tipo de violência, revendo suas ações em todos os momentos, tendo um olhar integral e diferenciado em relação aos alunos. É fundamental que o bullying não seja tratado como brincadeira de criança e para ser identificado e combatido é necessária uma ação entre a família e todos da escola, que pode ser desenvolvida através de projetos que ajudem a apontar caminhos para a solução do problema. Tais ações devem ser pautadas por constantes debates e reflexões, nas quais o aluno se torne o protagonista. Não existem fórmulas prontas, pois a intervenção deve ser feita através da realidade de cada escola.

  12. Capsazepine, a synthetic vanilloid that converts the Na,K-ATPase to Na-ATPase

    DEFF Research Database (Denmark)

    2008-01-01

    . Drawing on previous homology modeling studies of Na,K-ATPase to atomic models of sarcoplasmic reticulum Ca-ATPase and on kinetic data, we propose that CPZ uncouples an Na+ cycle from an Na+/K+ cycle in the pump. The Na+ cycle possibly involves transport through the recently characterized Na+-specific site...... regulatory communication with nucleotides takes place during turnover. Studies with lipid vesicles revealed that CPZ reduced ATP-dependent digitoxigenin-sensitive 22Na+ influx into K+ loaded vesicles only at saturating ATP concentrations. The drug apparently abolishes the regulatory effect of ATP on the pump....... A shift to such uncoupled mode is believed to produce pumps mediating uncoupled Na+ efflux by modifying the transport stoichiometry of single pump units. Udgivelsesdato: February 5...

Quanto ao tipo de afasia, 5 pacientes apresentavam déficits predominantemente de expressão e 10 apresentavam déficits receptivos e expressivos em graus equiparáveis. Em 6 casos a terapia foi iniciada dentro dos 3 primeiros meses de instalação do quadro; nos restantes foi iniciada mais tardiamente. Dos 15 pacientes, 11 apresentaram evolução satisfatória, a qual não depndeu do grau de afasia, do tipo de afasia, da idade do paciente, do tipo de patologia e do intervalo entre a instalação do quadro afásico e o início da terapia. A terapia da linguagem no paciente afásico é efetiva, o prognóstico não pode ser feito a priori. Somente a evolução do caso com sua retestagem criteriosa poderá dar dados realmente úteis para se falar em evolução.

  15. Gasotransmitters: Novel regulators of epithelial Na+ transport?

    Directory of Open Access Journals (Sweden)

    MikeAlthaus

    2012-04-01

    Full Text Available The vectorial transport of Na+ across epithelia is crucial for the maintenance of Na+ and water homeostasis in organs such as the kidneys, lung or intestine. Dysregulated Na+ transport processes are associated with various human diseases such as hypertension, the salt-wasting syndrome pseudohypoaldosteronism type 1, pulmonary edema, cystic fibrosis or intestinal disorders, which indicate that a precise regulation of epithelial Na+ transport is essential. Novel regulatory signaling molecules are gasotransmitters. There are currently three known gasotransmitters: nitric oxide (NO, carbon monoxide (CO and hydrogen sulfide (H2S. These molecules are endogenously produced in mammalian cells by specific enzymes and have been shown to regulate various physiological processes. There is a growing body of evidence, which indicates that gasotransmitters may also regulate Na+ transport across epithelia. This review will summarize the available data concerning NO, CO and H2S dependent regulation of epithelial Na+ transport processes and will discuss whether or not these mediators can be considered as true physiological regulators of epithelial Na+ transport biology.

  16. NaK handling and removal

    International Nuclear Information System (INIS)

    Sodium-potassium alloy is used in specific application in French Fast Breeder Reactors as: cold traps, NaK bubbler for argon purification, valves and also in experimental irradiation devices. lt has been preferred to sodium because it is liquid from + 7 deg. C for the most common peritectic alloy. After its use, NaK is considered as a hazardous waste (nuclear or not) due to its high reactivity with air and water. The most important risk remains in handling NaK systems which have not been operated for some time. The NaK will be covered with a crust of the superoxide K02 which is a strong oxidising agent. Thermodynamically, K02 will react with most organic material or metallic dust or swarfs and can also react with additional NaK to give sufficient heat to boil part of the NaK, resulting in a sudden increase in pressure and small explosions. We describe the formation given to experimenters in our Sodium School and the CEA's experience in treating specific devices for transportation, decanting of tanks, tank opening and NaK removal.

  2. Capsazepine, a synthetic vanilloid that converts the Na,K-ATPase to Na-ATPase.

    Science.gov (United States)

    Mahmmoud, Yasser A

    2008-02-01

    Capsazepine (CPZ), a synthetic capsaicin analogue, inhibits ATP hydrolysis by Na,K-ATPase in the presence but not in the absence of K(+). Studies with purified membranes revealed that CPZ reduced Na(+)-dependent phosphorylation by interference with Na(+) binding from the intracellular side of the membrane. Kinetic analyses showed that CPZ stabilized an enzyme species that constitutively occluded K(+). Low-affinity ATP interaction with the enzyme was strongly reduced after CPZ treatment; in contrast, indirectly measured interaction with ADP was much increased, which suggests that composite regulatory communication with nucleotides takes place during turnover. Studies with lipid vesicles revealed that CPZ reduced ATP-dependent digitoxigenin-sensitive (22)Na(+) influx into K(+)-loaded vesicles only at saturating ATP concentrations. The drug apparently abolishes the regulatory effect of ATP on the pump. Drawing on previous homology modeling studies of Na,K-ATPase to atomic models of sarcoplasmic reticulum Ca-ATPase and on kinetic data, we propose that CPZ uncouples an Na(+) cycle from an Na(+)/K(+) cycle in the pump. The Na(+) cycle possibly involves transport through the recently characterized Na(+)-specific site. A shift to such an uncoupled mode is believed to produce pumps mediating uncoupled Na(+) efflux by modifying the transport stoichiometry of single pump units. PMID:18230728

  3. Dependence of Na-K pump current on internal Na+ in mammalian cardiac myocytes.

    Mogul, D J; Singer, D H; Ten Eick, R E

    1990-08-01

    Na-K pump current (Ipump) is a function of the intracellular Na+ concentration [( Na+]i). We examined the quantitative relationship between Ipump and [Na+]i in isolated guinea pig ventricular myocytes under steady-state conditions. [Na+]i was controlled and "clamped" at several selected concentrations using wide-tipped pipette microelectrodes, and membrane current was measured using the whole cell patch voltage-clamp technique. Ipump generated at a holding potential of -40 mV was determined by measuring the change in steady-state holding current before and during exposure to dihydroouabain (1 mM); Ipump was measured at 11 levels of [Na+]i ranging from 0 to 80 mM (n = 63) with only one measurement per cell and normalized to cell capacitance to account for differences between myocytes in sarcolemmal surface area. Ipump exhibited a nonlinear dependence on [Na+]i; a Hill analysis of the relationship yielded a half-maximal [Na+]i for pump stimulation of 43.2 mM and a Hill coefficient of 1.53. An alternative analysis of the experimental data was performed assuming that occupation of three internal binding sites by Na+ is required for enzyme turnover. Regression analysis gave the best fit when only two different binding affinities (KD) are postulated. The values are KD1 = 1 mM, KD2 = KD3 = 29 mM. From the analysis using the latter model, the level of [Na+]i at which Ipump saturated closely approximated the theoretical saturation level calculated from published estimates of pump turnover rate and density. The maximal sensitivity of the Na-K pump to changes in [Na+]i occurs when internal [Na+] is within the range for the normal resting physiological level. PMID:2167023

    The heat capacity of the mass selected Na41+ cluster has been measured using a differential nanocalorimetry method. A two-peak structure appears in the heat capacity curve of Na41+, whereas Schmidt and co-workers [ M. Schmidt, J. Donges, Th. Hippler, and H. Haberland, Phys. Rev. Lett. 90, 103401 (2003) ] observed, within their experimental accuracy, a smooth caloric curve. They concluded from the absence of any structure that there is a second order melting transition in Na41+ with no particular feature such as premelting. The observed difference with the latter results is attributed to the better accuracy of our method owing to its differential character. The two structures in the heat capacity are ascribed to melting and premelting of Na41+. The peak at lower temperature is likely due to an anti-Mackay to Mackay solid-solid transition.

  7. Na+-H+ exchange and Na+-dependent transport systems in streptozotocin diabetic rat kidneys

    International Nuclear Information System (INIS)

    The streptozotocin-induced diabetic rat was used to test the hypothesis that Na+-H+ exchange activity in the proximal tubule luminal membrane would be increased in association with renal hypertrophy, altered glomerular hemodynamics, enhanced filtered load and tubular reabsorption of 22Na+, and stimulated 22Na= pump activity in the basolateral membrane, previously reported characteristics of this experimental animal model. Amiloride-sensitive H+ gradient-dependent Na+ uptake and Na+ gradient-dependent H+ flux were increased in brush-border membrane vesicles from the streptozotocin-treated animals. Na+ gradient-dependent uptakes of phosphate, D-glucose, L-proline, and myoinositol were decreased in the drug-induced diabetic animals. These membrane transport alterations were not found when the streptozotocin-diabetic animals were treated with insulin

  14. Theoretical study of Na(4p2P)+Na(3s2S) and Cd(5p3P0)+Na(3s2S) collisions and their role in the energy transfer between Cd* and Na

    International Nuclear Information System (INIS)

    We have computed the cross sections for the energy transfer process Cd(5p3P0) + Na(3s2S) →Cd(5s1S) + Na(4p2P) and for the state changing collision Na(4p2P) + Na(3s2S)→Na(3d2D) + Na(3s2S), based on theoretical interaction potentials for the NaCd and Na2 systems, respectively. Our calculations shed light on the interpretation of experiments with laser excited Na+Cd vapour mixtures. It turns out that Cd(5p3P0), in rapid equilibrium with the doorway state Cd(5p3P1), efficiently transfers energy to Na, populating the 4p2P state. The collisions with ground state Na cause a very fast conversion of the 4p2P to the 3d2D state, from which the strongest emission is observed. (orig.)

    2016-01-01

    Purpose : The aim of this paper is to study the elastic Coulomb breakup of $^{34}$Na on $^{208}$Pb to give us a core of $^{33}$Na with a neutron and in the process we try and investigate the one neutron separation energy and the ground state configuration of $^{34}$Na. Method : A fully quantum mechanical Coulomb breakup theory within the architecture of post-form finite range distorted wave Born approximation extended to include the effects of deformation is used to research the elastic Coulomb breakup of $^{34}$Na on $^{208}$Pb at 100 MeV/u. The triple differential cross-section calculated for the breakup is integrated over the desired components to find the total cross-section, momentum and angular distributions as well as the average momenta, along with the energy-angular distributions. Results : The total one neutron removal cross-section is calculated to test the possible ground state configurations of $^{34}$Na. The average momentum results along with energy-angular calculations indicate $^{34}$Na to ha...

  1. Elastic Coulomb breakup of 34Na

    Science.gov (United States)

    Singh, G.; Shubhchintak, Chatterjee, R.

    2016-08-01

    Background: 34Na is conjectured to play an important role in the production of seed nuclei in the alternate r -process paths involving light neutron rich nuclei very near the β -stability line, and as such, it is important to know its ground state properties and structure to calculate rates of the reactions it might be involved in, in the stellar plasma. Found in the region of `island of inversion', its ground state might not be in agreement with normal shell model predictions. Purpose: The aim of this paper is to study the elastic Coulomb breakup of 34Na on 208Pb to give us a core of 33Na with a neutron and in the process we try and investigate the one neutron separation energy and the ground state configuration of 34Na. Method: A fully quantum mechanical Coulomb breakup theory within the architecture of post-form finite range distorted wave Born approximation extended to include the effects of deformation is used to research the elastic Coulomb breakup of 34Na on 208Pb at 100 MeV/u. The triple differential cross section calculated for the breakup is integrated over the desired components to find the total cross-section, momentum, and angular distributions as well as the average momenta, along with the energy-angular distributions. Results: The total one neutron removal cross section is calculated to test the possible ground state configurations of 34Na. The average momentum results along with energy-angular calculations indicate 34Na to have a halo structure. The parallel momentum distributions with narrow full widths at half-maxima signify the same. Conclusion: We have attempted to analyze the possible ground state configurations of 34Na and in congruity with the patterns in the `island of inversion' conclude that even without deformation, 34Na should be a neutron halo with a predominant contribution to its ground state most probably coming from 33Na(3 /2+)⊗ 2 p3 /2ν configuration. We also surmise that it would certainly be useful and rewarding to test our

  2. Na+ uptake into colonic enterocyte membrane vesicles

    International Nuclear Information System (INIS)

    Na+ uptake was studied in colonic enterocyte membrane vesicles prepared from normal and dexamethasone-treated rats. Vesicles from rats treated with dexamethasone demonstrated a fivefold greater 22Na+ uptake compared with vesicles from normal rats. Most of the tracer uptake in membranes derived from treated rats occurred through a conductive, amiloride-blockable pathway located in vesicles with low native K+ permeability and high Cl- permeability. Kinetic analysis of the amiloride inhibition curve revealed the presence of two amiloride-blockable pathways, one with a high affinity accounting for 85% of the uptake, and one with a low affinity accounting for only 12% of the uptake. Only the low-affinity pathway was detected with vesicles from normal rats. The high sensitivity to amiloride, the dependence on dexamethasone pretreatment, and the relative permeabilities to K+ and Cl- indicate that most of the 22Na+ uptake in membranes derived from treated rats is through a Na+-specific channel located in apical membrane vesicles. Preincubation of the isolated cells from dexamethasone-treated rats at 37 degree C in Ca2+-free solutions before homogenization and membrane vesicle purification caused a 5- to 10-fold increase in amiloride-blockable 22Na+ uptake compared with vesicles derived from cells maintained at 0 degree C. The addition of Ca2+, but not of Mg2+, to the incubation solution markedly reduced this temperature-dependent enhancement in 22Na+ uptake. These results suggest that Na+ transport in colonic enterocytes from dexamethasone-treated rats is regulated by a Ca2+-dependent, temperature-sensitive process which causes a sustained change in the apical membrane

  8. NaI(Tl) electron energy resolution

    International Nuclear Information System (INIS)

    NaI(Tl) electron energy resolution ηe was measured using the Modified Compton Coincidence Technique (MCCT). The MCCT allowed detection of nearly monoenergetic internal electrons resulting from the scattering of incident 662 keV gamma rays within a primary NaI(Tl) detector. Scattered gamma rays were detected using a secondary HPGe detector in a coincidence mode. Measurements were carried out for electron energies ranging from 16 to 438 keV, by varying the scattering angle. Measured HPGe coincidence spectra were deconvolved to determine the scattered energy spectra from the NaI(Tl) detector. Subsequently, the NaI(Tl) electron energy spectra were determined by subtracting the energy of scattered spectra from the incident source energy (662 keV). Using chi-squared minimization, iterative deconvolution of the internal electron energy spectra from the measured NaI(Tl) spectra was then used to determine ηe at the electron energy of interest. ηe values determined using this technique represent variations in light production from monoenergetic electrons, light collection at the photomultiplier tube (PMT) photocathode, photoelectron production, photoelectron collection at the first dynode, and PMT gain, as well as noise from the accompanying electronics. It has been found that the electron energy resolution varies from 24.8% at 16 keV to 6.7% at 438 keV. Results from this study can be used to verify the significance of the different contributions to intrinsic energy resolution

  9. Electron induced sodium emission from NaCl surface

    International Nuclear Information System (INIS)

    Experimental data are presented on the sputtering of NaCl surface by electrons with varying electron current density and at different target temperatures. The Na D doublet intensity due to sputtering of excited Na atoms has been simultaenously measured with the neutral Na flux. The results can be understood if it is assumed that the neutral Na atoms vaporize from partially sodium covered surface and can subsequently be excited in electron - atom collisions. (Author)

  10. Summer sudden Na number density enhancements measured with the ALOMAR Weber Na Lidar

    2008-05-01

    Full Text Available We present summer Na-densities and atmospheric temperatures measured 80 to 110 km above the Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR. The Weber Na Lidar is part of ALOMAR, located at 69° N in Norway, 150 km north of the Arctic Circle. The sun does not set here during the summer months, and measurements require a narrowband Faraday Anomalous Dispersion Optical Filter (FADOF.

    We discuss an observed sudden enhancement in the Na number density around 22:00 UT on 1 to 2 June 2006. We compare this observation with previous summer measurements and find a frequent appearance of Na number density enhancements near local midnight. We describe the time of appearance, the altitude distribution, the duration and the strength of these enhancements and compare them to winter observations. We investigate possible formation mechanisms and, as others before, we find a strong link between these Na number density enhancements and sporadic E layers.

    Metallic Na was formed in NaCl single crystals with irradiation of a variety of radiation sources and analyzed the physical states with several methods. In the case of irradiation of 21 MeV electron pulses to the crystal blocks, the optical absorption and lifetime measurement of positron annihilation indicated appearance of Na clusters inside. Radiation effects of electron beam of 30 keV to the crystals in vacuum showed the appearance of not only metallic Na but atomic one during irradiation with Auger electron spectroscopy. Intense photon fluxes in vacuum ultraviolet region of synchrotron radiation were used as another source and an analyzing method of ultraviolet photoelectron spectroscopy. The results showed the metallic Na layered so thick that bulk plasmon can exist. (author)

    Here we report the quasielastic neutron scattering and FTIR studies on the dynamics of propylene adsorbed in Na-Y and Na-ZSM5 zeolites. QENS data show that although the mechanism of translational motion of propylene is jump diffusion in both the cases of Na-Y and Na-ZSM5 zeolites, the diffusivity is affected by the host size and is hindered in the case of Na-ZSM5. FTIR studies showed that guest–host interaction in Na-ZSM5 is stronger than that in Na-Y zeolite corroborating the QENS results.

    Na(+),K(+)-ATPase pumps three Na(+) ions out of cells in exchange for two K(+) taken up from the extracellular medium per ATP molecule hydrolysed, thereby establishing Na(+) and K(+) gradients across the membrane in all animal cells. These ion gradients are used in many fundamental processes, notably excitation of nerve cells. Here we describe 2.8 Å-resolution crystal structures of this ATPase from pig kidney with bound Na(+), ADP and aluminium fluoride, a stable phosphate analogue, with and without oligomycin that promotes Na(+) occlusion. These crystal structures represent a transition state preceding the phosphorylated intermediate (E1P) in which three Na(+) ions are occluded. Details of the Na(+)-binding sites show how this ATPase functions as a Na(+)-specific pump, rejecting K(+) and Ca(2+), even though its affinity for Na(+) is low (millimolar dissociation constant). A mechanism for sequential, cooperative Na(+) binding can now be formulated in atomic detail. PMID:24089211

    The aim of the NA61/SHINE ion programme is to explore the QCD phase diagram within the range of thermodynamical variables accessible by the SPS. Moreover the experiment provides precision hadron production measurements to improve computation of neutrino fluxes in neutrino oscillation experiments and for improving air shower simulations of cosmic-ray experiments. The main physics goals of the NA61/SHINE ion programme are the study of the properties of the onset of deconfinement and the search for signatures of the critical point of strongly interacting matter. These goals are pursued by performing an energy (beam momentum 13A – 158 A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan. This paper reviews the status and results of the NA61/SHINE experiment.

    The distribution of Na and Sr between feldspar (albite-Sr-celsian series) and a salt-bearing fluid at 700 deg C and 2 kbar was studied experimentally. The distribution of the elements between feldspar and the fluid is not ideal. Strontium enriches feldspar relative to the fluid over the entire compositional range. The unit cell parameters of the albite-Sr-celsian solid solutions were refined. The experimental data are used to calculate the excess volumes and energies of mixing of the solid solutions of (Na, Sr)-feldspars, which are approximated by a two-parameter Margules model. 28 refs., 6 figs., 6 tabs

    2010-01-01

    Včasih sem se spraševala, zakaj moram vsak teden hoditi na ure klavirja in solfeggia ter se zaradi tega ne morem udeležiti likovnega krožka. Kasneje sem opustila izobraževanje v glasbi in sem se posvetila likovnemu ustvarjanju oziroma slikarstvu. V precej drugačni obliki so se prav tako med glasbo in slikarstvom odločali danes priznani slikarji. Tako se je na primer slikar Paul Klee odločil za slikarstvo, saj bi po lastnem mnenju glasbo lahko samo poustvarjal. Vendar pa je glasba ostala priso...

Vsak trgovalec ima svojo predstavo o trgu in lahko iz enakih informacij naredi drugačne zaključke kot nek drug trgovalec. Zaradi tega je danes vse bolj v veljavi trgovanje na osnovi algoritmov, ki vedno sprejmejo enako odločitev, in sicer glede na parametre, ki jih trgovalec želi vstaviti v strategijo. Prav tako lahko rezultate ene strategije primerjamo z rezultati druge strategije, saj vemo, da je končni rezultat p...

    2014-01-01

    Problematika pojasnjevanja spreobrnitve v alternativne religije je v evro-ameriški znanosti prisotna že več kot eno stoletje. V drugi polovici 20. stoletja je s pojavom modela pranja možganov spreobrnitev postala celo kontroverzna populistična tema. Zadnji dve desetletji, ko model pranja možganov zaradi neustrezne argumentacije izgublja na veljavi, je prevladujoči model postal procesualen model. V Sloveniji se srečujemo v glavnem s nedodelanimi aplikacijami v znanosti opuščenega modela pranja...

  5. Role of the Na(+)-translocating NADH:quinone oxidoreductase in voltage generation and Na(+) extrusion in Vibrio cholerae.

    For Vibrio cholerae, the coordinated import and export of Na(+) is crucial for adaptation to habitats with different osmolarities. We investigated the Na(+)-extruding branch of the sodium cycle in this human pathogen by in vivo (23)Na-NMR spectroscopy. The Na(+) extrusion activity of cells was monitored after adding glucose which stimulated respiration via the Na(+)-translocating NADH:quinone oxidoreductase (Na(+)-NQR). In a V. cholerae deletion mutant devoid of the Na(+)-NQR encoding genes (nqrA-F), rates of respiratory Na(+) extrusion were decreased by a factor of four, but the cytoplasmic Na(+) concentration was essentially unchanged. Furthermore, the mutant was impaired in formation of transmembrane voltage (ΔΨ, inside negative) and did not grow under hypoosmotic conditions at pH8.2 or above. This growth defect could be complemented by transformation with the plasmid encoded nqr operon. In an alkaline environment, Na(+)/H(+) antiporters acidify the cytoplasm at the expense of the transmembrane voltage. It is proposed that, at alkaline pH and limiting Na(+) concentrations, the Na(+)-NQR is crucial for generation of a transmembrane voltage to drive the import of H(+) by electrogenic Na(+)/H(+) antiporters. Our study provides the basis to understand the role of the Na(+)-NQR in pathogenicity of V. cholerae and other pathogens relying on this primary Na(+) pump for respiration. PMID:26721205

  6. Study on Na layer response to geomagnetic activities based on Odin/OSIRIS Na density data

    The Na layer is normally distributed from 80 to 110 km, and the height range is corresponding to the ionospheric D and E region. In the polar region, the energetic particles precipitating from the magnetosphere can often penetrate into the E region and even into the D region. Thus, the influence of the energetic particles to the Na layer is one of interests in the aspect of the atmospheric composition change accompanied with the auroral activity. There are several previous studies in this issue. For example, recently, we have reported an initial result on a clear relationship between the electron density increase (due to the energetic particles) and the Na density decrease from observational data sets obtained by Na lidar, EISCAT VHF radar, and optical instruments at Tromsoe, Norway on 24-25 January 2012. However, all of the previous studies had been carried out based on case studies by ground-based lidar observations. In this study, we have performed, for the first time, statistical analysis using Na density data from 2004 to 2009 obtained with the Optical Spectrograph and InfraRed Imager System (OSIRIS) onboard Odin satellite. In the presentation, we will show relationship between the Na density and geomagnetic activities, and its latitudinal variation. Based on these results, the Na layer response to the energetic particles will be discussed.

  7. The role of Na/+/ in transport processes of bacterial membranes

    Science.gov (United States)

    Lanyi, J. K.

    1979-01-01

    Until recently it was generally held that transport in bacteria was linked exclusively to proton circulation, in contrast to most eucaryotic systems, which depended on Na(+) circulation. The present review is intended to trace recent developments which have led to the discarding of this idea. The discussion covers transport of Na(+) and other cations, effects of Na(+) and Na(+) gradients on metabolite transport, properties of Na(+)-dependent transport carriers, and evolutionary considerations of Na(+) transport. It is now apparent that the transport of Na(+) is an important part of energy metabolism in bacteria, and that Na(+) gradients as well as H(+) gradients are used in these systems for the conservation and transmission of energy. Two hypotheses are proposed to explain the evolution of Na/K systems, and it is presently difficult to decide between them.

    The NA48 Collaboration is rebuilding its drift chambers ready for the experiment to start up again this coming July. An intricate task involving the soldering of over 24,000 wires! The future of the NA48 experiment is coming right down to the wire, that is, the wires which the Collaboration is installing in the clean room of Hall 887 on the Prévessin site. Six days a week, technicians are working in shifts to rebuild the experiment's drift chambers. The original chambers were damaged when a section of a vacuum tube imploded at the end of 1999. A year ago, CERN gave the green light for this essential part of the spectrometer to be rebuilt, so the NA48 experiment, which studies CP violation (see box), still has a bright future ahead of it.

A partir dos descritores controlados (DeCS "biossegurança" e "odontologia", procederam-se a busca na Literatura Latino-Americana e do Caribe em Ciências da Saúde, na Scientific Electronic Library Online, na National Library of Medicine e na Biblioteca Cochrane. Resultados: Com a associação entre os DeCS, chegou-se a 66 artigos, porém, após refinamento foram incluídos nesta revisão 12 artigos. Nos resultados foi evidenciado que a produção científica sobre biossegurança é vasta, bem como é ampla na odontologia, contudo, quando da concentração de trabalhos contempladores da associação dos termos biossegurança e odontologia, a quantidade de estudos diminui consideravelmente. Não obstante, as pesquisas foram, em sua maioria, desenvolvidas por estudiosos nacionais, da região nordeste e evidenciaram que o conhecimento e a adoção de medidas de segurança biológica na área ainda são insuficientes para garantir a proteção da equipe e dos pacientes qualitativamente. Conclusão: Sugere-se que as normas de precaução padrão sejam seguidas rigidamente e que ações de educação sejam promovidas entre os profissionais.

  10. The solubility of Cr(OH)3(am) in concentrated NaOH and NaOH-NaNO3 solutions

    International Nuclear Information System (INIS)

    Chromium is a major component of the Hanford waste tank sludges, and the presence of Cr in the sludges is a significant concern in the disposal of these sludges because Cr can interfere with the formation of waste glasses. One of the current pretreatment strategies for removing constituents that can interfere with glass formation, such as P and Cr, is to wash/dissolve the sludges in basic NaOH solutions. The solubility of Cr(OH)3(am) was measured in concentrated NaOH ranging in concentration from 0.1M to 6.0M and in NaOH-NaNO3 solutions with fixed NaOH concentration and variable NaNO3 concentration at room temperature (22--23 C). Equilibrium between solids and solutions was approached relatively slowly and required approximately 60--70 days before steady-state concentrations were reached. A thermodynamic model, based upon the Pitzer equations, was developed from the solubility data in NaOH, which includes only two aqueous Cr species (Cr(OH)4- and NaCr(OH)4(aq)) and ion-interaction parameters for Na+ with Cr(OH)4-. This model was then tested in the mixed NaOH-NaNO3 solutions and found to be reliable

  11. Laser trapping of 21Na atoms

    International Nuclear Information System (INIS)

    This thesis describes an experiment in which about four thousand radioactive 21Na (tl/2 = 22 sec) atoms were trapped in a magneto-optical trap with laser beams. Trapped 21Na atoms can be used as a beta source in a precision measurement of the beta-asymmetry parameter of the decay of 21Na → 21Ne + Β+ + ve, which is a promising way to search for an anomalous right-handed current coupling in charged weak interactions. Although the number o trapped atoms that we have achieved is still about two orders of magnitude lower than what is needed to conduct a measurement of the beta-asymmetry parameter at 1% of precision level, the result of this experiment proved the feasibility of trapping short-lived radioactive atoms. In this experiment, 21Na atoms were produced by bombarding 24Mg with protons of 25 MeV at the 88 in. Cyclotron of Lawrence Berkeley Laboratory. A few recently developed techniques of laser manipulation of neutral atoms were applied in this experiment. The 21Na atoms emerging from a heated oven were first transversely cooled. As a result, the on-axis atomic beam intensity was increased by a factor of 16. The atoms in the beam were then slowed down from thermal speed by applying Zeeman-tuned slowing technique, and subsequently loaded into a magneto-optical trap at the end of the slowing path. The last two chapters of this thesis present two studies on the magneto-optical trap of sodium atoms. In particular, the mechanisms of magneto-optical traps at various laser frequencies and the collisional loss mechanisms of these traps were examined

    The $^{24}$Mg($p$, $\\alpha$)$^{21}$Na reaction was measured at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory in order to better constrain spins and parities of energy levels in $^{21}$Na for the astrophysically important $^{17}$F($\\alpha, p$)$^{20}$Ne reaction rate calculation. 31 MeV proton beams from the 25-MV tandem accelerator and enriched $^{24}$Mg solid targets were used. Recoiling $^{4}$He particles from the $^{24}$Mg($p$, $\\alpha$)$^{21}$Na reaction were detected by a highly segmented silicon detector array which measured the yields of $^{4}$He particles over a range of angles simultaneously. A new level at 6661 $\\pm$ 5 keV was observed in the present work. The extracted angular distributions for the first four levels of $^{21}$Na and Distorted Wave Born Approximation (DWBA) calculations were compared to verify and extract angular momentum transfer.

    A study was made of a high specific energy battery based on a sodium negative electrode and a chlorine positive electrode with molten AlCl3-NaCl electrolyte and a solid beta alumina separator. The basic performance of a Na beta-alumina NaAlCl4, Cl2/C circulating cell at 200 C was demonstrated. This cell can be started at 150 C. The use of melting sodium chloroaluminate electrolyte overcomes some of the material problems associated with the high working temperatures of present molten salt systems, such as Na/S and LiAl/FeS, and retains the advantages of high energy density and relatively efficient electrode processes. Preliminary investigations were conducted on a sodium-chlorine static cell, material compability, electrode design, wetting, and theoretical calculations to assure a better chance of success before assembling a Na/Cl2 circulating cell. Mathematical models provide a theoretical explanation for the performance of the NaCl2 battery. The results of mathematical models match the experimental results very well. According to the result of the mathematical modeling, an output at 180 mA/sq cm and 3.2 V can be obtained with optimized cell design.

    1996-11-01

    Many forming methods are in common use for engineering ceramics. Of these, slip casting is an ideal forming method because of its low cost, simplicity and flexibility, potential for uniform particle packing and suitability to the production of articles of intricate shape. Slip casting nonclay materials, such as alumina, requires the use of both a deflocculant and a binder. There are many commercially available deflocculants and binders that can be tested in alumina casting slips. However, determination of a suitable deflocculant/binder combination and quantification of the optimal additions of the deflocculant/binder pair can be time consuming. Certain deflocculants are capable of acting as binders. One such additive is sodium carboxymethylcellulose (Na-cmc), a cellulose ether. Na-cmc is a powerful binder. It is a member of the carbohydrate binder group--the binder group with the strongest binding power. It is capable of acting as a deflocculant in glazes and nonclay casting slips.

  13. NaI(Tl) response functions

    International Nuclear Information System (INIS)

    The response functions of a NaI(Tl) detector have been estimated using Monte Carlo methods. Response functions were calculated for monoenergetic photon sources (0.05 to 3 MeV). Responses were calculated for point-like sources and for sources distributed in Portland cement cylinders. The responses were used to calculate the efficiency functions in term of photon energy. Commonly, sources used for calibration are point-like, and eventually sources to be measured have different features. In order to use the calibrated sources corrections due to solid angle, self-absorption and scattering, must be carried out. However, some of these corrections are not easy to perform. In this work, the calculated responses were used to estimate the detector efficiency of point-like sources, and sources distributed in Portland type cement. Samples of Portland paste were prepared and were exposed to photoneutrons produced by a 15 MV linac. Some of the elements in the cement were activated producing γ-emitting radionuclides that were measured with a NaI(Tl) gamma-ray spectrometer, that was calibrated with point-like sources. In order to determine the specific activity in the induced radioisotopes calculated efficiencies were used to make corrections due to the differences between the solid angle, photon absorption and photon scattering in the point-like calibration sources and the sources distributed in cement. During the interaction between photoneutrons and the cement samples three radioisotopes were induced: 56Mn, 24Na, and 28Al. (Author)

  14. TRP-Na(+)/Ca(2+) Exchanger Coupling.

    Science.gov (United States)

    Harper, Alan G S; Sage, Stewart O

    2016-01-01

    Na(+)/Ca(2+) exchangers (NCXs) have traditionally been viewed principally as a means of Ca(2+) removal from non-excitable cells. However there has recently been increasing interest in the operation of NCXs in reverse mode acting as a means of eliciting Ca(2+) entry into these cells. Reverse mode exchange requires a significant change in the normal resting transmembrane ion gradients and membrane potential, which has been suggested to occur principally via the coupling of NCXs to localised Na(+) entry through non-selective cation channels such as canonical transient receptor potential (TRPC) channels. Here we review evidence for functional or physical coupling of NCXs to non-selective cation channels, and how this affects NCX activity in non-excitable cells. In particular we focus on the potential role of nanojunctions, where the close apposition of plasma and intracellular membranes may help create the conditions needed for the generation of localised rises in Na(+) concentration that would be required to trigger reverse mode exchange.

  17. Resonances production from the NA60 experiment

    2012-11-01

    Full Text Available The NA60 experiment at the CERN SPS has studied light vector meson production in In-In collisions at 158A GeV. The ϕ meson was detected via both the K+K− and the μ+μ− decay channels. The yields and inverse slope parameters of the mT spectra observed in the two channels are compatible within errors, different from the large discrepancies seen in Pb-Pb collisions between the hadronic (NA49 and dimuon (NA50 decay channels. In the invariant mass region 0.2 1 GeV, the excess is found to be prompt, with remarkable differences with respect to the Drell-Yan process. The Teff slope parameter, extracted from the transverse mass spectra, shows a rise with mass up to the ρ, followed by a sudden decline for higher masses. The former is consistent with radial flow of a hadronic source, while the latter suggests a dominantly partonic emission source.

  6. Reactions of metal oxides with molten NaPO3 + NaCl mixtures

    International Nuclear Information System (INIS)

    We consider the dissolution mechanism for iron (III), europium(III), and tin(IV) oxides in molten NaPO3 + NaCl that are responsible for the peak solubilities. We chose Fe2O3 as the basic material since this occurs in large amounts around damaged metal structures in rock salt mines in a proposed zone for storing vitrified radioactive wastes. Solubility measurement and paper chromatography show that Fe2O3 dissolves in molten NaPO3 + NaCl in air by reaction with the solvent to give double iron and sodium diphosphates and monophosphates in accordance with the initial solution-in-the-melt composition, the degree of equilibration, and the temperature. The elevated solubilities for initial NaCl contents close to 30 mole % are due to sodium triphosphates and tricyclophosphates present in these melts. Moessbauer spectroscopy confirms that double iron, europium and tin diphosphates and monophosphates containing sodium occur in these chloride-polyphosphate melts

  7. Acidosis differentially modulates inactivation in NaV1.2, NaV1.4, and NaV1.5 channels

    Directory of Open Access Journals (Sweden)

    PeterRuben

    2012-06-01

    Full Text Available NaV channels play a crucial role in neuronal and muscle excitability. Using whole-cell recordings we studied effects of low extracellular pH on the biophysical properties of NaV1.2, NaV1.4, and NaV1.5, expressed in cultured mammalian cells. Low pH produced different effects on different channel subtypes. Whereas NaV1.4 exhibited very low sensitivity to acidosis, primarily limited to partial block of macroscopic currents, the effects of low pH on gating in NaV1.2 and NaV1.5 were profound. In NaV1.2 low pH reduced apparent valence of steady-state fast inactivation, shifted the τ(V to depolarizing potentials and decreased channels availability during onset to slow and use-dependent inactivation. In contrast, low pH delayed open-state inactivation in NaV1.5, right-shifted the voltage-dependence of window current, and increased channel availability during onset to slow and use-dependent inactivation. These results suggest that protons affect channel availability in an isoform-specific manner. A computer model incorporating these results demonstrates their effects on membrane excitability.

  9. Synthesis of Na-A and/or Na-X zeolite/porous carbon composites from carbonized rice husk

    International Nuclear Information System (INIS)

    Na-A and/or Na-X zeolite/porous carbon composites were prepared under hydrothermal conditions by NaOH dissolution of silica first from carbonized rice husk followed by addition of NaAlO2 and in situ crystallization of zeolites i.e., using a two-step process. When a one-step process was used, both Na-A and Na-X zeolites crystallized on the surface of carbon. Na-A or Na-X zeolite crystals were prepared on the porous carbonized rice husk at 90 deg. C for 2-6 h by changing the SiO2/Al2O3, H2O/Na2O and Na2O/SiO2 molar ratios of precursors in the two-step process. The surface area and NH4+-cation exchange capacity (CEC) of Na-A zeolite/porous carbon were found to be 171 m2/g and 506 meq/100 g, respectively, while those of Na-X zeolite/porous carbon composites were 676 m2/g and 317 meq/100 g, respectively. Na-A and Na-X zeolites are well-known microporous and hydrophilic materials while carbonized rice husk was found to be mesoporous (pores of ∼3.9 nm) and hydrophobic. These hybrid microporous-mesoporous and hydrophilic-hydrophobic composites are expected to be useful for decontamination of metal cations as well as organic contaminants simultaneously. - Graphical Abstract: Novel Na-X zeolite/porous carbon composite.

  11. Na+-K+ pump in chronic renal failure

    International Nuclear Information System (INIS)

    This review summarizes the evidence for the defect in Na+-K+ pump in chronic renal failure, considers the role of various factors in causing this defect, and discusses the clinical implications thereof. Intracellular Na is elevated in erythrocytes, leukocytes, and muscle cells from some patients with chronic renal failure (CRF). Recent evidence suggest that this elevation of cell Na may be, in large part, a consequence of decreased number of Na+-K+ pump units per cell. Maintenance dialysis over a period of weeks ameliorates the defect in intracellular Na+, and this improvement is contemporaneous with an increase in the number of Na+-K+ pump sites per cell. In erythrocytes with normal cell Na+, acute hemodialysis increases the rate of 22Na+ and 42K+ transport. Many factors such as the presence of retained toxic metabolite or circulating inhibitor in the uremic plasma, or biochemical changes produced by acute hemodialysis, may explain this finding. In cells with high cell Na+, the pump-mediated 42K+ transport is normalized at the expense of a raised cell Na+. The decreased muscle membrane potential in uremic subjects has been attributed to a decreased activity of Na+-K+ pump. The authors discuss the role of hormonal abnormalities and circulating inhibitors, which may cause an acute inhibition of the pump and of other factors such as K+ depletion, which may cause more chronic alterations. The implications of alteration of Na+ and K+ pump transport and raised cell Na+ on other non-pump-mediated transport pathways are discussed. Raised cell Na+ may be a marker for the adequacy of maintenance dialysis in patients with end-stage renal failure

    A simple coprecipitation technique has been used successfully for the preparation of pure, ultrafine, single phases of NaNbO3 (NN) and NaTaO3 (NT). An alcoholic solution of ammonium carbonate and ammonium hydroxide was used to precipitate Na+ and Nb5+ (or Ta5+) cations under basic conditions as carbonate and hydroxide, respectively. On heating at 700°C, these precursors produce respective products. For comparison, both NN and NT powders were also prepared by the traditional solid state method. The phase purity and lattice parameters were studied by powder X-ray diffraction (XRD). The particle size and morphology were studied by scanning electron microscopy (SEM).

  13. Recovery of the heavy elements by NaY AND NaZSM-5 sorbant materials

    International Nuclear Information System (INIS)

    Porous sorbants as zeolites have a several applications in differents fiels: industrial gas purification, catalysis, transformation hydrocarbures prosesses and exchange ions. The hiogh capacity to exchange their cations with those of aqueous solutions was known (1). Since the accession of synthetic zeolites, these silicates have invaded the market and the firstindustrial applications were in exchange field. Studies at Battelle Northwest in Rchland, Washington have shown that zeolites may be used in treatment of radioactive wastes (2). The used method for storing the isotopes is based on selective removal by ion exchange. Clinoptilolite, zeolite (modernite), NaA, and AW-500 have been used. In this context, the present work deals with the recovery of heavy metals like lead and uranium using some microporous materials. The obtained results show that NaY faujasite and NaZSM-5 of the FAU- and MFI-type structure respectively are very effective in removing these elements from waste water

  14. Reaction of metal oxides with molten mixtures NaPO3+NaCl

    International Nuclear Information System (INIS)

    By methods of solubility determination and paper chromatography it is shown, that Fe2O3 solution in NaPO3+NaCl melts in the air relizes due to its chemical interaction with solvent resulting in formation of iron and sodium binary di- and monophosphates depending on melt-solvent initial composition, its attainment of equilibrium state and experiment temperature. It is established, that oxides increased solubility in melts with NaCl initial content ∼30 mol.% is specified by sodium tri- and tricyclophosphates presence in the melts. On this basis of NGR-spectroscopy data the presence of iron, europium, tin and sodium binary di- and monophosphates in some chloride-polyphosphate melts is confirmed

    Oxidized starch, one of the most important starch derivatives, has many different properties and applications. Currently, there are two ways to produce oxidized starch, through specific and nonspecific oxidation. Specific oxidation using the stable nitroxyl radical, 2,2,6,6-tetramethyl preparidinloxy (TEMPO), with NaBr and NaClO can produce oxidized starches with different properties under good quality control. In the current study, we examine the products of specifically oxidized starch. As the amount of oxidant and the temperature, two critical factors impacting the oxidation of starch were thoroughly investigated. Analysis of the molecular weight (MW), degree of oxidization (DO) and the detailed structures of corresponding products was accomplished using gel permeation chromatography with multi-angle laser light scattering (GPC-MALLS), infrared (IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and quadrapole time-of-flight mass spectrometry (Q/TOF-MS). According to the analytical results, the oxidation patterns of starch treated with specific oxidant TEMPO-NaBr-NaClO were established. When high amounts of oxidant was applied, more glucose residues within starch were oxidized to glucuronic acids (higher DO) and substantial degradation to starch oligosaccharides was observed. By selecting a reaction temperature of 25°C a high DO could be obtained for a given amount of oxidant. The reducing end sugar residue within oxidized starch was itself oxidized and ring opened in all TEMPO-NaBr-NaClO reactions. Furthermore, extra oxidant generated additional novel structures in the reducing end residues of some products, particularly in low temperature reactions. PMID:27112871

    Full Text Available O reconhecimento oficial da fitoterapia na odontologia no Brasil veio acompanhado de diversas lacunas na pesquisa científica e na utilização de plantas medicinais, especificamente para espécies vegetais com aplicação nas doenças da cavidade oral. O estado do Amazonas, especificamente a cidade de Manaus, não possui um diagnóstico da aplicabilidade de plantas medicinais nos serviços de atenção Odontológica. Esse estudo propôs realizar um estudo do tipo quali-quantitativo, descritivo e exploratório visando o levantamento da comercialização de plantas medicinais e o estudo etnobotânico para identificação das principais plantas medicinais indicadas e utilizadas nas patologias orais nos atendimentos odontológicos ambulatoriais na cidade de Manaus. Foram entrevistados 197 usuários do serviço odontológico, 150 Cirurgiões-Dentistas, e 47 comerciantes credenciados na prefeitura Municipal de Manaus. A amostragem foi realizada por acessibilidade ou conveniência para os Cirurgiões-Dentistas, enquanto os usuários foram selecionados através de amostragem aleatória simples, e os comerciantes de plantas medicinais foram entrevistados em sua totalidade. Os resultados demonstraram a existência de comercialização de plantas medicinais para patologias orais, destacando-se as seguintes espécies: Pedra ume cãa (Aulomyrcia sphareocarpa, Crajiru (Arrabidae chica, além da planta, sem identificação botânica, conhecida popularmente como Sara tudo. Entre os Cirurgiões-Dentistas e entre os pacientes, apenas 8% e 7,61%, respectivamente, utilizaram plantas medicinais para alterações patológicas orais. Os autores concluíram que as plantas medicinais comercializadas na cidade de Manaus são utilizadas de maneira empírica e que, apesar da Política Nacional de Práticas Integrativas e Complementares (PNPIC, novas políticas públicas de saúde devem inserir plantas medicinais e fitoterápicos de uso oral na rede pública de saúde na

  7. 1 nA Beam position monitor

    International Nuclear Information System (INIS)

    A new BPM system, based on resonant cavities, has been developed for measuring the transverse position of very low-intensity electron beams delivered to Experimental Hall B at the Continuous Electron Beam Accelerator Facility (CEBAF) in Newport News. VA. The system requirements called for measuring down to 1 nA with a 100 m m resolution. The actual system is much better: it can measure down to 100 pA at the 100 m m required resolution. A 100 pA beam yields about 1 electron per bunch. Each 1 nA BPM utilizes three resonant RF cavities to determine the position of the beam: one cavity sensitive to X position, a second cavity sensitive to Y position, and a third cavity which measures intensity. The position cavities operate at room temperature in a dipole type mode at 1497 MHz and contain internal field perturbing rods in an arrangement similar to that of the CEBAF rf Separator cavities. The position cavities are electron beam welded assemblies made of copper plated stainless steel. The RF output signal from each cavity is processed using a down-converter and a DSP based commercial lock-in amplifier operating at 100 kHz. The lock-in amplifiers connect to the EPICS control system via an IEEE 488 bus. System features under development include intensity and position modulation measurement capabilities. This paper provides measured performance results and an updated overview of the installed and operational 1 nA BPM system. copyright 1998 American Institute of Physics

    The response functions of a NaI(Tl) detector have been estimated using Monte Carlo methods. Response functions were calculated for monoenergetic photon sources (0.05 to 3 MeV). Responses were calculated for point-like sources and for sources distributed in Portland cement cylinders. The responses were used to calculate the efficiency functions in term of photon energy. Commonly, sources used for calibration are point-like, and eventually sources to be measured have different features. In order to use the calibrated sources corrections due to solid angle, self-absorption and scattering, must be carried out. However, some of these corrections are not easy to perform. In this work, the calculated responses were used to estimate the detector efficiency of point-like sources, and sources distributed in Portland type cement. Samples of Portland paste were prepared and were exposed to photoneutrons produced by a 15 MV linac. Some of the elements in the cement were activated producing γ-emitting radionuclides that were measured with a NaI(Tl) gamma-ray spectrometer, that was calibrated with point-like sources. In order to determine the specific activity in the induced radioisotopes calculated efficiencies were used to make corrections due to the differences between the solid angle, photon absorption and photon scattering in the point-like calibration sources and the sources distributed in cement. During the interaction between photoneutrons and the cement samples three radioisotopes were induced: {sup 56}Mn, {sup 24}Na, and {sup 28}Al. (Author)

  10. Dependence of thermoluminescence in LiF:Mg,Cu,Na,Si phosphor on Na dopant concentration and thermal treatment

    International Nuclear Information System (INIS)

    A new phosphor, LiF:Mg,Cu,Na,Si, has been developed in this laboratory for thermoluminescence. The thermoluminescence dependence on the concentration of Na dopant between 0 mol% and 0.45 mol% and thermal treatment between 240 deg. C and 310 deg. C was investigated. With an increase of Na concentration, the TL sensitivity and the main peak increase when the annealing temperature is less than 300 deg. C. With an increase of annealing temperature, the position of the main glow peak shifts markedly towards higher temperatures, irrespective of Na concentrations. The height of the main peak depends strongly on the annealing temperature. TL sensitivity remains stable at annealing temperatures from 260 deg. C to 300 deg. C for 0 mol% Na concentration, from 250 deg. C to 300 deg. C for 0.05 mol% N concentration, from 260 deg. C to 290 deg. C for 0.1 mol% Na concentration, from 260 deg. C to 280 deg. C for 0.2 mol% Na concentration, from 250 deg.C to 270 deg. C for 0.35 mol% Na concentration, or from 260 deg. C to 280 deg. C for 0.45 mol% Na concentration. The ratio of the intensity annealed at 310 deg. C to the intensity annealed at 260 deg. C seems to be reduced with an increase of Na concentration. Thermal susceptibility of LiF:Mg,Cu,Na,Si appears to be associated with the Na concentration. The lower the Na concentration, the less sensitive the TL is to annealing temperature. The optimum Na dopant concentration was found to be 0%

    Full Text Available Com base na observação, durante anos de magistério superior, na área de desenho, dos alunos de Engenharia, Matemática, Arquitetura e Artes, quanto às dificuldades encontradas por eles no aprendizado de desenho, em especial da Geometria Descritiva, é que nos propusemos, em 1999, lecionar essa disciplina para os cursos de Arquitetura e Artes, adotando uma metodologia diferente da convencional, para despertar, no aluno, o gosto pela disciplina e o desenvolvimento de uma habilidade pouco trabalhada na escola: a visão espacial. Mostrar para os alunos que essa disciplina não é difícil, mas apenas diferente daquilo que estudaram até então, tornou-se nossa meta. A visão espacial é uma habilidade mental localizada no lado direito do cérebro e, assim, quanto mais lúdica for esta aprendizagem, será mais bem assimilada. A proposta é iniciada no sentido de se trabalhar primeiro com sólidos: neles estarão os pontos, retas e planos normalmente abordados na metodologia convencional, nessa ordem. Como conclusão, tem-se que o importante é ressaltar o grande avanço que a Geometria Descritiva traz para quem quer representar graficamente qualquer coisa. Onde há planejamento, projeto e representação gráfica, aí estará a Geometria Descritiva.During many years observing the teaching of design at the Engineering, Mathematics, Architeture and Arts courses, we can note the difficulties of the students to learn it, specially the descriptive geometry. Because of that, we decided to teach this discipline to the Architeture and Arts courses, using a new metodology to make the students motivated to study and to learn, and trying to develop their their spatial vision. We want to show to the students that this discipline is not so difficult as they think, but show them that is only different. The spatial vision is a mental skill found at the right side of the brain and the more soft the learning is, the more it is assimilated by the brain. The

    Integrated chorda tympani nerve responses to NaCl were studied in two mouse strains, an NaCl-preferring NZB/B1NJ and an NaCl-avoiding CBA/J. The NaCl responses of both strains had similar magnitude and were suppressed by amiloride to a similar extent. This suggests that peripheral gustatory responsiveness to NaCl is not the only mechanism underlying mouse strain variation in NaCl acceptance.

  6. Apical Na+ permeability of frog skin during serosal Cl- replacement.

    Science.gov (United States)

    Leibowich, S; DeLong, J; Civan, M M

    1988-05-01

    Gluconate substitution for serosal Cl- reduces the transepithelial short-circuit current (Isc) and depolarizes short-circuited frog skins. These effects could result either from inhibition of basolateral K+ conductance, or from two actions to inhibit both apical Na+ permeability (PapNa) and basolateral pump activity. We have addressed this question by studying whole-and split-thickness frog skins. Intracellular Na+ concentration (CcNa) and PapNa have been monitored by measuring the current-voltage relationship for apical Na+ entry. This analysis was conducted by applying trains of voltage pulses, with pulse durations of 16 to 32 msec. Estimates of PapNa and CcNa were not detectably dependent on pulse duration over the range 16 to 80 msec. Serosal Cl- replacement uniformly depolarized short-circuited tissues. The depolarization was associated with inhibition of Isc across each split skin, but only occasionally across the whole-thickness preparations. This difference may reflect the better ionic exchange between the bulk medium and the extracellular fluid in contact with the basolateral membranes, following removal of the underlying dermis in the split-skin preparations. PapNa was either unchanged or increased, and CcNa either unchanged or reduced after the anionic replacement. These data are incompatible with the concept that serosal Cl- replacement inhibits PapNa and Na,K-pump activity. Gluconate substitution likely reduces cell volume, triggering inhibition of the basolateral K+ channels, consistent with the data and conclusions of S.A. Lewis, A.G. Butt, M.J. Bowler, J.P. Leader and A.D.C. Macknight (J. Membrane Biol. 83:119-137, 1985) for toad bladder. The resulting depolarization reduces the electrical force favoring apical Na+ entry. The volume-conductance coupling serves to conserve volume by reducing K+ solute loss. Its molecular basis remains to be identified. PMID:2458472

    The decomposition kinetics and mechanism of titania slag in eutectic NaOH-NaNO3 system were studied in the temperature range 623 K to 723 K (350 °C to 450 °C). Decomposed products were examined using X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray spectroscopy. It has been identified that the main product is Na2TiO3 and the decomposition kinetics of titania slag followed a shrinking unreacted core model. It is proposed that the chemical reaction process was the rate determining step with apparent activation energy of 62.4 kJ/mol. NaNO3 was mainly acted as oxygen carrier and mass transport agent to lower the viscosity of the system. The purity of TiO2 obtained in the product was up to 99.3 pct. A flow diagram to produce TiO2 and to recycle the media was proposed.

    Full Text Available A gastronomia, além de ter importante relação com a economia, é uma forma expressiva da cultura dos indivíduos, desde o tipo de alimentos cultivados até a maneira de seu preparo e consumo. O presente artigo propõe-se a analisar a relação entre o enoturismo – centralizado na existência do vinho enquanto elemento gastronômico – e o fenômeno da pluriatividade na agricultura familiar, vista nos últimos anos como alternativa positiva para sua reprodução econômica e social. O fluxo turístico em regiões vitivinícolas gera novas oportunidades de trabalho e faz com que agricultores e suas famílias dividam a mão de obra agrícola, até então direcionada ao cultivo da uva e outros alimentos para subsistência, com atividades não agrícolas – como o artesanato, o acolhimento de visitantes em pousadas, a atuação em restaurantes, entre outras – como chance de subsistência. Este panorama transforma as realidades do mundo rural, alterando a relação do agricultor com a produção de alimentos e a forma como o mesmo os utiliza, além de reestruturar o ambiente sociocultural no seu entorno.

  14. Stimulation of Na+/K+ ATPase activity and Na+ coupled glucose transport by β-catenin

    International Nuclear Information System (INIS)

    Research highlights: → The oncogenic transcription factor β-catenin stimulates the Na+/K+-ATPase. → β-Catenin stimulates SGLT1 dependent Na+, glucose cotransport. → The effects are independent of transcription. → β-Catenin sensitive transport may contribute to properties of proliferating cells. -- Abstract: β-Catenin is a multifunctional protein stimulating as oncogenic transcription factor several genes important for cell proliferation. β-Catenin-regulated genes include the serum- and glucocorticoid-inducible kinase SGK1, which is known to stimulate a variety of transport systems. The present study explored the possibility that β-catenin influences membrane transport. To this end, β-catenin was expressed in Xenopus oocytes with or without SGLT1 and electrogenic transport determined by dual electrode voltage clamp. As a result, expression of β-catenin significantly enhanced the ouabain-sensitive current of the endogeneous Na+/K+-ATPase. Inhibition of vesicle trafficking by brefeldin A revealed that the stimulatory effect of β-catenin on the endogenous Na+/K+-ATPase was not due to enhanced stability of the pump protein in the cell membrane. Expression of β-catenin further enhanced glucose-induced current (Ig) in SGLT1-expressing oocytes. In the absence of SGLT1 Ig was negligible irrespective of β-catenin expression. The stimulating effect of β-catenin on both Na+/K+ ATPase and SGLT1 activity was observed even in the presence of actinomycin D, an inhibitor of transcription. The experiments disclose a completely novel function of β-catenin, i.e. the regulation of transport.

    The new compounds NaCoCr2(PO4)3, NaNiCr2(PO4)3, and Na2Ni2Cr(PO4)3 were synthesized by sol-gel method and their crystal structures were determined by using neutron powder diffraction data. These compounds were characterized by galvanometric cycling and cyclic voltammetry. NaCoCr2(PO4)3, NaNiCr2(PO4)3, and Na2Ni2Cr(PO4)3 crystallize with a stuffed α-CrPO4-type structure. The structure consists of a 3D-framework made of octahedra and tetrahedra that are sharing corners and/or edges generating channels along [100] and [010], in which the sodium atoms are located. Of significance, in the structures of NaNiCr2(PO4)3, and Na2Ni2Cr(PO4)3 a statistical disorder Ni2+/Cr3+ was observed on both the 8g and 4a atomic positions, whereas in NaCoCr2(PO4)3 the statistical disorder Co2+/Cr3+ was only observed on the 8g atomic position. When tested as negative electrode materials, NaCoCr2(PO4)3, NaNiCr2(PO4)3, and Na2Ni2Cr(PO4)3 delivered specific capacities of 352, 385, and 368 mA h g-1, respectively, which attests to the electrochemical activity of sodium in these compounds.

    2009-01-01

    In this work, zeolite NaA was successfully synthesized by a hydrothermal method using kaolin as a combined source for silica and alumina. Zeolite NaA with high static water adsorption was synthesized from the low-cost raw material, kaolin, and the reaction parameters were optimized. Metakaolin was obtained by calcining kaolin at temperatures ranged from 953 K to 1173 K. The synthesis mixture was pre-crystallized at 343 K and crystallized at 373 K successively. Zeolite NaA was obtained, which was confirmed by SEM, XRD and the water adsorption analysis. The optimized metakaolinization temperature was found at 973 K. The influence of Na2O/SiO2 molar ratio, pre-crystallization time and seed on the crystal- lization of NaA zeolite was investigated. A thorough mixing of metakaolin and NaOH solution was favourable for the nucleation/crystallization rate. The obtained NaA zeolite under the optimized conditions shows excellent crystallinity and static water adsorption of 28.0wt-%,which was higher than 25.9 wt-% of the commercial NaA zeolite. Kaolin was suggested to be a feasible and economical raw material for the practical industrial applications for NaA zeolite.

    Highlights: ► We modeled Al2O3–Na2O–SiO2 and Al2O3–Na2O–AlF3–NaF using the Modified Quasichemical Model in the Quadruplet Approximation. ► This assessment includes a very thorough review of all available experimental data for Al2O3–Na2O and Al2O3–Na2O–SiO2. ► The charge compensation effect in the SiO2-rich region of the (Al2O3 + Na2O + SiO2) system is modeled with a NaAl4+ cation. ► First detailed thermodynamic modeling of the (Al2O3 + Na2O + SiO2) ternary system. ► First thermodynamic modeling at all compositions and temperatures of the (Al2O3 + Na2O + AlF3 + NaF) reciprocal oxyfluoride system. - Abstract: All available thermodynamic and phase diagram data for the condensed phases of the (Al2O3 + Na2O), (Al2O3 + Na2O + SiO2), and (Al2O3 + Na2O + AlF3 + NaF) systems have been critically assessed. Model parameters for solid solutions and a single set of parameters for the liquid solution in the binary, ternary, and ternary reciprocal systems have been optimized and permit to reproduce most of the critically reviewed experimental data. The Modified Quasichemical Model in the Quadruplet Approximation was used for the oxyfluoride (mixture of molten oxides and salts) liquid solution, which exhibits strong first-nearest-neighbor and second-nearest-neighbor short-range order. This thermodynamic model takes into account both types of short-range order as well as the coupling between them. The charge compensation effect present in the (Al2O3 + Na2O + SiO2) system was taken into account by adding a (NaAl)4+ species in the liquid solution.

  20. Influenza virus neuraminidase (NA): a target for antivirals and vaccines.

    Jagadesh, Anitha; Salam, Abdul Ajees Abdul; Mudgal, Piya Paul; Arunkumar, Govindakarnavar

    2016-08-01

    Influenza, the most common infectious disease, poses a great threat to human health because of its highly contagious nature and fast transmissibility, often leading to high morbidity and mortality. Effective vaccination strategies may aid in the prevention and control of recurring epidemics and pandemics associated with this infectious disease. However, antigenic shifts and drifts are major concerns with influenza virus, requiring effective global monitoring and updating of vaccines. Current vaccines are standardized primarily based on the amount of hemagglutinin, a major surface antigen, which chiefly constitutes these preparations along with the varying amounts of neuraminidase (NA). Anti-influenza drugs targeting the active site of NA have been in use for more than a decade now. However, NA has not been approved as an effective antigenic component of the influenza vaccine because of standardization issues. Although some studies have suggested that NA antibodies are able to reduce the severity of the disease and induce a long-term and cross-protective immunity, a few major scientific issues need to be addressed prior to launching NA-based vaccines. Interestingly, an increasing number of studies have shown NA to be a promising target for future influenza vaccines. This review is an attempt to consolidate studies that reflect the strength of NA as a suitable vaccine target. The studies discussed in this article highlight NA as a potential influenza vaccine candidate and support taking the process of developing NA vaccines to the next stage. PMID:27255748

    2006-10-01

    A study of growth rates of NaClO3 and NaBrO3 has been carried out using a small growth cell by in situ observation. Normal growth rates of {100} faces of NaClO3 and {111} faces of NaBrO3 along $\\langle 110 \\rangle$ direction are measured under relatively high supersaturation ranging from 3–8%. In the initial stages of growth, {100}, {110} and {111} faces develop in NaClO3 and gradually all the faces are replaced by the {100} faces only. In the case of NaBrO3, mostly {111} faces develop with occasional occurrence of small {100} faces at the intersection of {111} faces. The growth mechanisms are investigated from growth rate vs supersaturation plots and from the observations of surface features. In the present supersaturation range, the growth mechanism appears to be due to two-dimensional growth mechanism.

    Full Text Available A noção de afeto está no campo do (desprazer, resultante de uma experiência afetiva de satisfação ou insatisfação, e que se manifesta nas necessidades do sujeito. Pode-se dizer que o afeto envolve a ambivalência de sentimentos, do mais agradável ao mais insuportável, e desempenha um papel estruturante para que o sujeito reencontre sua estrutura psíquica, exercendo uma ação mediadora e decisiva sobre a constituição do sujeito do desejo, orientando o seu projeto de vida, sua profissão, sua opção sexual, etc. Essa ambivalência de afetos deve ser exercitada na educação familiar e escolar, na fala e na escuta que o afeto (desprazeroso tem relevância e parece ser silenciado. O desprazer pode ser escandido pelos sintomas medo, depressão, irritabilidade, ansiedade, humilhação. Assim posto o bullying é também conhecido como a síndrome da humilhação. O objetivo da humilhação é a tentativa de destruição do sujeito; a perda da identificação revela um fantasma, na medida em que própria vítima se sente culpada por sofrer ou por estar sofrendo um ato esburacado porque uma das peças não é encontrada e, em lugar do encaixe, o que se mostra é um buraco, o que provoca a angústia entre quem perde e aquele que ganha. ABSTRACT: The notion of affect is thus in the field of (dis pleasure, resulting from an affective experience of satisfaction or dissatisfaction, and that manifests itself on the needs of the subject.

O fotoperíodo é traduzido em informações fisiológicas a partir da secreção de melatonina.Parece não haver barreiras morfofisiológicas para esta indolamina, isto é, a melatonina perfunde-se rapidamente em cada célula do organismo e em alguns casos interage com receptores e membrana situados na superfície celular, e parece estar ligada à ingestão de alimentos, crescimento e atividade locomotora de peixes. São moléculas importantes metabolizando espécies reativas de oxigênio a produtos inativos e, portanto, reduzindo o dano oxidativo.Este trabalho tem por objetivo fazer um breve levantamento em artigos recentes sobre luminosidade, melatonina e o estresse oxidativo em peixes, e correlaciona-los com piscicultura.

    Rationale Mutations in glycerol-3-phosphate dehydrogenase 1-like (GPD1-L) protein reduce cardiac Na+ current (INa) and cause Brugada Syndrome (BrS). GPD1-L has >80% amino acid homology with glycerol-3-phosphate dehydrogenase, which is involved in nicotinamide adenine dinucleotide (NAD)-dependent energy metabolism. Objective Therefore, we tested whether NAD(H) could regulate human cardiac sodium channels (Nav1.5). Methods and Results HEK293 cells stably expressing Nav1.5 and rat neonatal cardiomyocytes were used. The influence of NADH/NAD+ on arrhythmic risk was evaluated in wild-type or SCN5A+/− mouse heart. A280V GPD1-L caused a 2.48 ± 0.17-fold increase in intracellular NADH level (P<0.001). NADH application or co-transfection with A280V GPD1-L resulted in decreased INa (0.48 ± 0.09 or 0.19 ±0.04 of control group, respectively; P<0.01), which was reversed by NAD+, chelerythrine, or superoxide dismutase (SOD). NAD+ antagonism of the Na+ channel downregulation by A280V GPD1-L or NADH was prevented by a protein kinase A (PKA) inhibitor, PKAI6–22. The effects of NADH and NAD+ were mimicked by a phorbol ester and forskolin, respectively. Increasing intracellular NADH was associated with an increased risk of ventricular tachycardia (VT) in wild-type mouse hearts. Extracellular application of NAD+ to SCN5A+/− mouse hearts ameliorated the risk of VT. Conclusions Our results show that Nav1.5 is regulated by pyridine nucleotides, suggesting a link between metabolism and INa. This effect required protein kinase C (PKC) activation and was mediated by oxidative stress. NAD+ could prevent this effect by activating PKA. Mutations of GPD1-L may downregulate Nav1.5 by altering the oxidized to reduced NAD(H) balance. PMID:19745168

    MESSENGER entered orbit about Mercury on March 18, 2011. Since then, the Ultraviolet and Visible Spectrometer (UWS) channel of MESSENGER's Mercury Atmospheric and Surface Composition Spectrometer (MASCS) has been observing Mercury's exosphere nearly continuously. Daily measurements of Na brightness were fitted with non-uniform exospheric models. With Monte Carlo sampling we traced the trajectories of a representative number of test particles, generally one million per run per source process, until photoionization, escape from the gravitational well, or permanent sticking at the surface removed the atom from the simulation. Atoms were assumed to partially thermally accommodate on each encounter with the surface with accommodation coefficient 0.25. Runs for different assumed source processes are run separately, scaled and co-added. Once these model results were saved onto a 3D grid, we ran lines of sight from the MESSENGER spacecraft :0 infinity using the SPICE kernels and we computed brightness integrals. Note that only particles that contribute to the measurement can be constrained with our method. Atoms and molecules produced on the nightside must escape the shadow in order to scatter light if the excitation process is resonant-light scattering, as assumed here. The aggregate distribution of Na atoms fits a 1200 K gas, with a PSD distribution, along with a hotter component. Our models constrain the hot component, assumed to be impact vaporization, to be emitted with a 2500 K Maxwellian. Most orbits show a dawnside enhancement in the hot component broadly spread over the leading hemisphere. However, on some dates there is no dawn/dusk asymmetry. The portion of the hot/cold source appears to be highly variable.

  9. Microhardness studies on as-grown faces of NaClO3 and NaBrO3 crystals

    2002-12-01

    Single crystals of NaClO3 and NaBrO3 are grown from their aqueous solutions at a constant temperature of 35°C by slow evaporation by using good quality seed crystals. Systematic microhardness studies are made on as-grown faces of these crystals at various loads. Typical cracks are observed at the corners of the impressions in NaClO3 whereas in addition to the cracks at the corners microcracks also appeared in NaBrO3 crystals around the impressions. The impressions formed in NaBrO3 are not very clear as in NaClO3, a possible mechanism for it is discussed. The work hardening index number () for both these crystals is around 1.6 suggesting that these are moderately harder samples. The hardness studies point out that NaBrO3 is harder than NaClO3 ( ≈ 100 kg/mm2), this could be due to strong inter ionic forces acting between Na–Br in NaBrO3 crystals. Using Gilman’s empirical relation, hardness values are calculated from the values of elastic constants (44) and are found to be close to the experimental results.

    Crystallographic, magnetic and NMR properties of a NaxCoO2 single crystal with x~1 are presented. We identify the stoichiometric Na1CoO2 phase, which is shown to be a non-magnetic insulator, as expected for homogeneous planes of Co3+ ions with S=0. In addition, we present evidence that, because of slight average Na deficiency, chemical and electronic phase separation leads to a segregation of Na vacancies into the well-defined, magnetic, Na0.8CoO2 phase.

    We report here on the moisture and water stability of the promising Na-ion anode material Na2Ti3O7. Spontaneous Na+/H+ exchange is detected by PXRD after air exposure, forming solid solution compounds of the form Na2-xHxTi3O7 (0 < x < 2). By controlled ion exchange in aqueous solution two mixed compositions are prepared and their composition and structure are characterized with a panel of techniques. Both mixed compositions crystallize in C2/m space group like H2Ti3O7, and therefore Na+/H+ exchange is found to involve a structural transition from AA stacking of [TiO6] layers to AB stacking sequence. The electrochemical behaviour of the mixed compositions vs. Na+/Na is studied as well as that of an electrode of pure Na2Ti3O7 prepared in water media. The water-processed electrode is shown to exhibit a superior cycling stability and therefore the results obtained highlight the potential of Na2Ti3O7 as a green, low cost anode material for NIBs.

  12. Na+ and K+ levels in living cells: do they depend on the rate of outward transport of Na+?

    At 25 degrees C, frog sartorius muslces rapidly gained Na+ and lost K+ in iodoacetamide and pure nitrogen. Beginning at normal levels, the concentrations of these ions in the cells reached those in the surrounding Ringer solution in 140 min. Yet during that time the Na+ efflux rate showed no sign of the slowing down demanded by Na-pump theory. The data support the view that maintenance and alterations of N1+ levels in frog muslce cells reflect adsorption on protein sites and the solubility property of bulk phase water and are independent of the rate at which Na+ leaves the cell surface.

    Full Text Available OBJECTIVE: Advances in our knowledge of mental disorder (MD genetics have contributed to a better understanding of their pathophysiology. Nonetheless, several questions and doubts persist. Recent studies have focused on environmental influences in the development of MDs, and the advent of neuroscientific methodologies has provided new perspectives. Early life events, such as childhood stress, may affect neurodevelopment through mechanisms such as gene-environment interactions and epigenetic regulation, thus leading to diseases in adulthood. The aim of this paper is to review the evidence regarding the role of the environment, particularly childhood stress, in the pathophysiology of MD. METHODOLOGY: We reviewed articles that evaluated environmental influences, with a particular focus on childhood trauma, brain morphology, cognitive functions, and the development of psychopathology and MD. RESULTS AND CONCLUSION: MRI studies have shown that exposure to trauma at an early age can result in several neurostructural changes, such as the reduction of the hippocampus and corpus callosum. Cognitive performance and functioning are also altered in this population. Finally, childhood stress is related to an increased risk of developing MD such as depression, bipolar disorder, schizophrenia and substance abuse. We conclude that there is robust evidence of the role of the environment, specifically adverse childhood experiences, in various aspects of MD.OBJETIVO: Avanços no conhecimento da genética dos transtornos mentais (TM contribuíram para um melhor entendimento de suas bases fisiopatológicas.

    1982-01-01

    Computer simulations of tight epithelia under three experimental conditions have been carried out, using the rheogenic nonlinear model of Lew, Ferreira and Moura (Proc. Roy. Soc. London. B 206:53-83, 1979) based largely on the formulation of Koefoed-Johnsen and Ussing (Acta Physiol. Scand. 42: 298-308. 1958). First, analysis of the transition between the short-circuited and open-circuited states has indicated that (i) apical Cl- permeability is a critical parameter requiring experimental definition in order to analyze cell volume regulation, and (ii) contrary to certain experimental reports, intracellular Na+ concentration (ccNa) is expected to be a strong function of transepithelial clamping voltage. Second, analysis of the effects of lowering serosal K+ concentration (csK) indicates that the basic model cannot simulate several well-documented observations; these defects can be overcome, at least qualitatively, by modifying the model to take account of the negative feedback interaction likely to exist between the apical Na+ permeability and ccNa. Third, analysis of the strongly supports the concept that osmotically induced permeability changes in the apical intercellular junctions play a physiological role in conserving the body's stores of NaCl. The analyses also demonstrate that the importance of Na+ entry across the basolateral membrane is strongly dependent upon transepithelial potential, cmNa and csK; under certain conditions, net Na+ entry could be appreciably greater across the basolateral than across the apical membrane.

  4. Sepsis does not alter red blood cell glucose metabolism or Na+ concentration: A 2H-, 23Na-NMR study

    International Nuclear Information System (INIS)

    The effects of sepsis on intracellular Na+ concentration ([Na+]i) and glucose metabolism were examined in rat red blood cells (RBCs) by using 23Na- and 2H-nuclear magnetic resonance (NMR) spectroscopy. Sepsis was induced in 15 halothane-anesthetized female Sprague-Dawley rats by using the cecal ligation and perforation technique; 14 control rats underwent cecal manipulation without ligation. The animals were fasted for 36 h, but allowed free access to water. At 36 h postsurgery, RBCs were examined by 23Na-NMR by using dysprosium tripolyphosphate as a chemical shift reagent. Human RBCs from 17 critically ill nonseptic patients and from 7 patients who were diagnosed as septic were also examined for [Na+]i. Five rat RBC specimens had [Na+]i determined by both 23Na-NMR and inductively coupled plasma-atomic emission spectroscopy (ICP-AES). For glucose metabolism studies, RBCs from septic and control rats were suspended in modified Krebs-Henseleit buffer containing [6,6-2H2]glucose and examined by 2H-NMR. No significant differences in [Na+]i or glucose utilization were found in RBCs from control or septic rats. There were no differences in [Na+]i in the two groups of patients. The [Na+]i determined by NMR spectroscopy agreed closely with measurements using ICP-AES and establish that 100% of the [Na+]i of the RBC is visible by NMR. Glucose measurements determined by 2H-NMR correlated closely (correlation coefficient = 0.93) with enzymatic analysis. These studies showed no evidence that sepsis disturbed RBC membrane function or metabolism

    Monovalent ion traffic across the cell membrane occurs via various pathways. Evaluation of individual fluxes in whole cell is hampered by their strong interdependence. This difficulty can be overcome by computational analysis of the whole cell flux balance. However, the previous computational studies disregarded ion movement of the self-exchange type. We have taken this exchange into account. The developed software allows determination of unidirectional fluxes of all monovalent ions via the major pathways both under the balanced state and during transient processes. We show how the problem of finding the rate coefficients can be solved by measurement of monovalent ion concentrations and some of the fluxes. Interdependence of fluxes due to the mandatory conditions of electroneutrality and osmotic balance and due to specific effects can be discriminated, enabling one to identify specific changes in ion transfer machinery under varied conditions. To test the effectiveness of the developed approach we made use of the fact that Li/Na exchange is known to be an analogue of the coupled Na/Na exchange. Thus, we compared the predicted and experimental data obtained on U937 cells under varied Li+ concentrations and following inhibition of the sodium pump with ouabain. We found that the coupled Na/Na exchange in U937 cells comprises a significant portion of the entire Na+ turnover. The data showed that the loading of the sodium pump by Li/Na exchange involved in the secondary active Li+ transport at 1–10 mM external Li+ is small. This result may be extrapolated to similar Li+ and Na+ flux relationships in erythrocytes and other cells in patients treated with Li+ in therapeutic doses. The developed computational approach is applicable for studying various cells and can be useful in education for demonstrating the effects of individual transporters and channels on ion gradients, cell water content and membrane potential.

    KIMS-NaI is a direct detection experiment searching for Weakly Interacting Massive Particles (WIMP) via their scattering off of nuclei in a NaI(Tl) crystal. The KIMS-NaI collaboration has carried out tests of six crystals in the Yangyang underground laboratory in order to develope low-background NaI(Tl) crystals. Studies of internal backgrounds crystals have been performed with the goal of reducing backgrounds levels to 1 dru at 2 keV. Pulse shape discrimination (PSD) capabilities were also investigated for distinguishing between WIMP nuclear recoil signals and electron recoil backgrounds. The PSD analysis was applied to underground data with one low background NaI(Tl) detector and the evaluation of WIMP mass limit is ongoing.

    Molecular dynamics simulations of the dissociation of methane hydrate in aqueous NaCl solutions are performed. It is shown that the dissociation of the hydrate is accelerated by the formation of methane bubbles both in NaCl solutions and in pure water. We find two significant effects on the kinetics of the hydrate dissociation by NaCl. One is slowing down in an early stage before bubble formation, and another is swift bubble formation that enhances the dissociation. These effects arise from the low solubility of methane in NaCl solution, which gives rise to a nonuniform spatial distribution of solvated methane in the aqueous phase. We also demonstrate that bubbles form near the hydrate interface in dense NaCl solutions and that the hydrate dissociation proceeds inhomogeneously due to the bubbles. PMID:25237735

  11. Thermochemistry in the systems Na-O-C, Na-Al-O-C and Na-C-N with respect to interactions of oxygen, carbon and nitrogen in sodium

    International Nuclear Information System (INIS)

    Thermochemical calculations have been performed in the systems Na-O-C, Na-Al-O-C and Na-C-N. Metallurgical phase diagrams are presented in the temperature range 700 K-1100 K. At T >= 932 K Na2CO3 can be in equilibrium with sodium and strong interactions between dissolved carbon and oxygen are therefore expected. This conclusion agrees with experimental results of Ainsley et al. If Al2O3 or Al is added to the system, the field of existence of sodium is limited by NaAlO2 and graphite, while Na2O, Na2CO3 and Al2O3 cannot be in equilibrium with Na anymore. If the carbon activities are high enough, Al4C3 is stable in sodium even in the presence of NaAlO2. Measurements of the carbon solubility in which alumina crucibles are used can therefore result in too high solubilities because of formation of Al4C3. The system Na-C-N is described in the temperature range 800 K-1000 K taking into account Na3N, NaCN and Na2NCN. Nitrogen pressures larger than about 1 atm result in Na/Na2NCN equilibria if saturation of the sodium is achieved. This might be a reason for the extremely low solubility of nitrogen in sodium in contrast to nitrogen in Lithium, where the terminal solubility is determined by Li3N. (orig.)

    In NaCl and KCl aqueous nonisothermal solutions K+ inverts its sense of migration within the physiological concentration range; Na+ behaves similarly at much lower concentrations. These findings are discussed in relation to solute induced modifications of water structure and of their influence on thermal diffusion. A possible evolutionary model of a thermodiffusive mechanism for the sodium potassium pump is also suggested

  16. Corrosion Behaviours of Copper Alloy in Solutions Containing Na2SO4 and NaCl with Different Concentrations

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Potentiodynamic polarisation, potential-time measurements, X-ray diffraction (XRD) and infrared spectroscopy (IR)have been used to investigate the effect of different concentrations of Na2SO4 in the absence and presence of NaCl,on the corrosion of Cu-alloy. The electrochemical measurements showed that the increase of Na2SO4 concentration led to increase the corrosion current density of Cu alloy and vice versa. The presence of NaCl shifted the potential to more cathodic potential, which had a great influence on the protectiveness of the Cu oxide layer formed on the surface in presence of Na2SO4. The spectrometric measurements indicated the constituents of the film formed on the alloy surface were mainly Cu2O, in addition to the oxides, NiO and Fe2O3, which were traced by XRD analysis.

    The dark matter interpretation of the DAMA modulation signal depends on the NaI(Tl) scintillation efficiency of nuclear recoils. Previous measurements for Na recoils have large discrepancies, especially in the DAMA/LIBRA modulation energy region. We report a quenching effect measurement of Na recoils in NaI(Tl) from 3keV$_{\\text{nr}}$ to 52keV$_{\\text{nr}}$, covering the whole DAMA/LIBRA energy region for light WIMP interpretations. By using a low-energy, pulsed neutron beam, a double time-of-flight technique, and pulse-shape discrimination methods, we obtained the most accurate measurement of this kind for NaI(Tl) to date. The results differ significantly from the DAMA reported values at low energies, but fall between the other previous measurements. We present the implications of the new quenching results for the dark matter interpretation of the DAMA modulation signal.

    For dense sintered ceramic samples of Na2Zr2SiP2O12 and Na3Zr2Si2PO12 the ionic conductivities were measured between 20 and 4600C, and the crystal structures were refined at 25 and 3000C. The Na3Zr2Si2PO12 phase at 3000C has the highest ionic conductivity and is the only one of those studied here where the pathway from Na(1) to Na(2) is the widest and where the Na(2) site has a higher relative occupancy than the Na(1) site.

    A NaF-NaCl-KCl ternary system containing La2O3 was investigated for the preparation of Al-La master alloy by the thermite reaction method. The solubility of La2O3 in NaF-NaCl-KCl molten salt was determined by the method of isothermal solution saturation. Inductively coupled plasma-optical emission spectroscopy and x-ray diffraction (XRD) analyses were used to consider the content of La2O3 in molten salt and the supernatant composition of molten salt after dissolution of La2O3, respectively. The results showed that the content of NaF had a positive influence on the solubility of La2O3 in NaF-NaCl-KCl molten salts, and the solubility of La2O3 could reach 8.71 wt.% in molten salts of 50 wt.%NaF-50 wt.% (44 wt.%NaCl + 56 wt.%KCl). The XRD pattern of cooling molten salt indicated the formation of LaOF in molten salt, which was probably obtained by the reaction between NaF and La2O3. The kinetic study showed that the thermite reaction was in accord with a first-order reaction model. The main influence factors on La content in the Al-La master alloy product, including molten salt composition, amount of Al, concentration of La2O3, stirring, reduction time and temperature, were investigated by single-factor experimentation. The content of La in the Al-La master alloy could be reached to 10.1 wt.%.

    The Institute of Gas Technology (IGT), under subcontract to M-C Power Corporation under DOE funding, has been operating bench-scale fuel cells to investigate the performance and endurance issues of the Li/Na electrolyte because it offers higher ionic conductivity, higher exchange current densities, lower vapor pressures, and lower cathode dissolution rates than the Li/K electrolyte. These cells have continued to show higher performance and lower decay rates than the Li/K cells since the publication of our two previous papers in 1994. In this paper, test results of two long-term 100-cm{sup 2} bench scale cells are discussed. One cell operated continuously at 160 mA/cm{sup 2} for 17,000 hours with reference gases (60H{sub 2}/20CO{sub 2}/20H{sub 2}O fuel at 75% utilization and 30CO{sub 2}/70 air oxidant humidified at room temperature at 50% utilization). The other cell operated at 160 mA/cm{sup 2} for 6900 hours at 3 atm with system gases (64H{sub 2}/16CO{sub 2}/20H{sub 2}O at 75% utilization and an M-C Power system-defined oxidant at 40% utilization). Both cells have shown the highest performance and longest endurance among IGT cells operated to date.

    The NA48 experiment at the CERN SPS accelerator is making a measurement of the direct CP violation parameter epsilon '/ epsilon by comparing the four rates of decay of K/sub S/ and K/sub L/ into 2 pi /sup 0/ and pi /sup +/ pi /sup -/. To reconstruct the decays into 2 pi /sup 0/ the information from the almost 13500 channels of a quasi-homogeneous liquid krypton electromagnetic calorimeter is used. The readout electronics of the calorimeter has been designed to provide a dynamic range from a few MeV to about 50 GeV energy deposition per cell, and to sustain a high rate of incident particles. The system is made by cold charge preamplifiers (working at 120 degrees K), low-noise fast shapers followed by digitizer electronics at 40 MHz sampling rate that employs a gain switching technique to expand the dynamic range, where the gain can be selected for each sample individually (i.e. every 25 ns). To reduce the amount of data collected the system contains a zero suppression circuit based on halo expansion. (12 refs)...

  5. Thermodynamics of the NaCl–KCl system

    International Nuclear Information System (INIS)

    Highlights: • The complementary methods of DSC, DTA, DROP and XRD analyses were used. • The heat capacity of solid phase of the NaCl–KCl mixtures was measured. • The heat capacity of liquid phase of the 50NaCl–50KCl mixture was obtained. • The enthalpy of fusion and solid solution formation were determined. • The thermodynamic functions of the 50NaCl–50KCl mixture were calculated. - Abstract: The heat capacity of the solid phase of the NaCl–KCl mixtures was measured by the differential scanning calorimetry. These results and X-ray diffraction data were used for the explanation of the solid solution formation. The heat capacity of the liquid phase of the eutectic 50NaCl–50KCl mixture has been obtained in a closed glass container. The enthalpy increment (H°T − H°298.15) and the fusion enthalpy of the 50NaCl–50KCl mixture have been measured by a drop calorimeter. The joint analysis of these values with the heat capacity data allowed the calculation of the enthalpy of the solid solution. As the final result, the thermodynamic functions of the eutectic 50NaCl–50KCl mixture have been obtained

  6. Na/Ca selectivity coefficients of Na-montmorillonite at different temperatures

    International Nuclear Information System (INIS)

    Document available in extended abstract form only. The Finnish spent nuclear fuel disposal is based on the KBS-3 concept in crystalline bedrock. The concept aims at long-term isolation and containment of spent fuel in copper canisters surrounded by bentonite buffer which mostly consists of montmorillonite. The cation form affects many essential properties of montmorillonite. In the KBS-3 concept, the maximum temperature limit has been decided as 90 C. The thermal period when spent fuel is supplying heat may last for thousands of years. Thus, for the long-term modelling of the chemical processes in the buffer, the cation-exchange selectivity coefficients have to be known at different temperatures. However, the selectivities for montmorillonite have mostly been studied at room temperature. In this work, the cation-exchange selectivity coefficients and cation-exchange isotherms are determined in batch experiments for montmorillonite at three different temperatures (25, 50 and 75 C). Five different ratios of NaClO4/Ca(ClO4)2 are used in the experimental solutions. After equilibration the solution and montmorillonite are separated and both are analyzed to get the desired exchange parameters. The experiments are modelled with a computational model (PHREEQC), which is capable of taking into account the physicochemical processes that take place in the experiment. The purification is needed to enable accurate experimental results and to exclude any unnecessary complexes and mineral reactions in the montmorillonite. MX-80 bentonite obtained from Wyoming (USA) in powdered form is first purified to Na-montmorillonite form. The purification comprised the removal of large particles, dissolution of carbonates and iron oxides, removal of organic material, changing to the sodium form and removal of the excess salt by washing and finally by dialysis. After the purification the montmorillonite was dried in an oven at 60 C and finally placed in a vacuum freeze dryer. The Na

  7. Electron scattering in graphene with adsorbed NaCl nanoparticles

    International Nuclear Information System (INIS)

    In this work, the results of contactless magnetoconductance and Raman spectroscopy measurements performed for a graphene sample after its immersion in NaCl solution were presented. The properties of the immersed sample were compared with those of a non-immersed reference sample. Atomic force microscopy and electron spin resonance experiments confirmed the deposition of NaCl nanoparticles on the graphene surface. A weak localization signal observed using contactless magnetoconductance showed the reduction of the coherence length after NaCl treatment of graphene. Temperature dependence of the coherence length indicated a change from ballistic to diffusive regime in electron transport after NaCl treatment. The main inelastic scattering process was of the electron-electron type but the major reason for the reduction of the coherence length at low temperatures was additional, temperature independent, inelastic scattering. We associate it with spin flip scattering, caused by NaCl nanoparticles present on the graphene surface. Raman spectroscopy showed an increase in the D and D′ bands intensities for graphene after its immersion in NaCl solution. An analysis of the D, D′, and G bands intensities proved that this additional scattering is related to the decoration of vacancies and grain boundaries with NaCl nanoparticles, as well as generation of new on-site defects as a result of the decoration of the graphene surface with NaCl nanoparticles. The observed energy shifts of 2D and G bands indicated that NaCl deposition on the graphene surface did not change carrier concentration, but reduced compressive biaxial strain in the graphene layer

  9. Respiratory complex I: A dual relation with H(+) and Na(+)?

    Respiratory complex I couples NADH:quinone oxidoreduction to ion translocation across the membrane, contributing to the buildup of the transmembrane difference of electrochemical potential. H(+) is well recognized to be the coupling ion of this system but some studies suggested that this role could be also performed by Na(+). We have previously observed NADH-driven Na(+) transport opposite to H(+) translocation by menaquinone-reducing complexes I, which indicated a Na(+)/H(+) antiporter activity in these systems. Such activity was also observed for the ubiquinone-reducing mitochondrial complex I in its deactive form. The relation of Na(+) with complex I may not be surprising since the enzyme has three subunits structurally homologous to bona fide Na(+)/H(+) antiporters and translocation of H(+) and Na(+) ions has been described for members of most types of ion pumps and transporters. Moreover, no clearly distinguishable motifs for the binding of H(+) or Na(+) have been recognized yet. We noticed that in menaquinone-reducing complexes I, less energy is available for ion translocation, compared to ubiquinone-reducing complexes I. Therefore, we hypothesized that menaquinone-reducing complexes I perform Na(+)/H(+) antiporter activity in order to achieve the stoichiometry of 4H(+)/2e(-). In agreement, the organisms that use ubiquinone, a high potential quinone, would have kept such Na(+)/H(+) antiporter activity, only operative under determined conditions. This would imply a physiological role(s) of complex I besides a simple "coupling" of a redox reaction and ion transport, which could account for the sophistication of this enzyme.

    Baptista, Filipa Isabel Cabaço

    2012-01-01

    A retinopatia diabética é uma das principais causas de perda de visão e cegueira no mundo. Esta patologia é considerada uma doença vascular. No entanto, tem sido demonstrado que a parte neural da retina também é afetada, mesmo antes de serem detetadas lesões microvasculares. As alterações registadas em eletroretinogramas de pacientes e animais diabéticos, e a perda de sensibilidade à cor e ao contraste são sinais precoces de disfunção neuronal na retina. Contudo, as alterações ...

    Male zajednice koje žive na marginama razvoja općenito se suočavaju s brojnim problemima i izazovima. Premda je opstojnost njihova glavna briga, integracija u glavne razvojne tokove paradoksalno ostaje dalek i nerješiv problem. Stoga ovaj članak ima tri cilja. Prvo, u njemu se bavimo socio-ekonomskom dinamikom Sarawak-Kalimantan pograničnih zajednica čija sela ostaju izvan glavnih tokova razvoja. Nedavno su sela i manji gradovi uz ovu granicu privukli pažnju medija, političara,...

    We describe the use of {sup 18}F-NaF positron emission tomography (PET) whole-body imaging for the evaluation of skeletal trauma in a case of suspected child abuse. To our knowledge, 18F NaF PET has not been used in the past for the evaluation of child abuse. In our patient, this technique detected all sites of trauma shown by initial and follow-up skeletal surveys, including bilateral metaphyseal fractures of the proximal humeri. Fluorine-18 NaF PET has potential advantage over Tc-99m-labeled methylene diphosphonate (MDP) based upon superior image contrast and spatial resolution. (orig.)

    2003-01-01

    The X$^{1}\\Sigma ^{+}$ state of NaRb was studied by Fourier transform spectroscopy. An accurate potential energy curve was derived from more than 8800 transitions in isotopomers $^{23}$Na$^{85}$Rb and $^{23}$Na$^{87}$Rb. This potential reproduces the experimental observations within their uncertainties of 0.003 \\rcm to 0.007 \\rcm. The outer classical turning point of the last observed energy level ($v''=76$, $J''=27$) lies at $\\approx 12.4$ \\AA, leading to a energy of 4.5 \\rcm below the ground state asymptote.
