The legislative and fiscal influences of Congress, as well as the continuing overall growth in health care spending as a portion of the gross domestic product, make congressional representation by physicians important because physicians have unique expertise in the impact of legislation on patient care and medical practice. To describe physician representation in the US Congress between 1960 and 2004 and relate the results to past representation of physicians in Congress. A retrospective observational study of members of the US Congress from all 50 states and all represented territories, who served from January 1960 to April 2004 (including 108th Congress), using data available in public access databases and congressional biographical records. Physician representation in Congress, including occupation before taking office, state/territory of representation, sex, party affiliation, and time served. During the past 44 years, 25 (1.1%) of 2196 members of Congress were physicians. Physicians in Congress were more likely to be members of the Republican Party (60% vs 45.1% of all members, P = .007) and were similar to other members of Congress in mean years of service (9.2 years for physicians vs 12.3 years for all members, P = .09) and in sex distribution (4.0% female physicians vs 6.8% all female members, P = .57). Physicians in Congress represented 17 states, the Virgin Islands, and Puerto Rico. Physician representation in Congress is low and is in stark contrast with physician roles during the first century of the United States. However, the 8 physicians currently serving in Congress may be indicative of a shift toward more direct influence of physicians in national politics.

Azam, Mohd; Rai, Vineet Kumar; Mohanty, Deepak Kumar

2017-09-01

TeO2-Pb3O4 (TPO) glasses codoped with Nd3+ and Yb3+ ions have been fabricated by conventional melting technique. The absorption, emission and excitation spectra of the samples have been recorded. The optical band gap in both the doped/codoped glasses is found to be ˜3.31 eV. Judd-Ofelt analysis has been carried out by using the absorption spectrum of 0.8 mol% Nd3+ doped glass to determine the radiative properties viz radiative transition probabilities, branching ratios, radiative lifetimes, quality factor and emission cross sections of some emitting levels for Nd3+ ions. The radiative transition probability for the 4G7/2 → 4I9/2 transition (˜1926 Hz) is found to be maximum compared to other 4G5/2 → 4I9/2 (˜1622 Hz) and 4F5/2 → 4I9/2 (˜865 Hz) transitions. Upconversion (UC) luminescence of the samples has been examined by the 980 nm CW diode laser excitation. Effect of addition of Yb3+ ions in the Nd3+ doped glasses on UC emission intensity has been discussed. The UC emission intensity corresponding to the green, red and NIR bands in the codoped glass has been enhanced by ˜17, ˜12 and ˜42 times as compared to that of the Nd3+ singly doped glass. The quantum efficiency for the 4G7/2 level is found to be ˜32%. The nephelauxetic ratio, bonding parameter and covalency of Nd3+ ions have been found positive which represents the covalent bonding between Nd3+ ion and oxygen atom. The colour tunability from yellowish-green to dominant green region has been obtained in the optimized codoped TPO glass.

Goldenberg, Matthew N

2015-11-01

Physicians occupy a prominent position in the US healthcare system, and physicians who serve in Congress may bring a particular perspective, expertise, and influence to health-related legislation. The purpose of this study was to describe physician membership in the US Congress between 2005 and 2015. Congressional biographical records were searched to identify physicians who served in the US Congress from 2005 to 2015. Political and demographic characteristics of physician-members were compared with those of nonphysician-members of Congress and of all US physicians. The numbers of physicians in recent Congresses also were compared with those in each Congress since 1945. A total of 27 physicians representing 17 states have served in Congress since 2005. There has been a significant increase in physician representation since 1987, reaching a high of 20 members (3.7%) in the Congresses immediately following passage of the Patient Protection and Affordable Care Act. Physician-members were mostly men (93%) and more likely than their Congressional colleagues to be Republican (78% vs 53% of all members, P = 0.007) and from the South (63% vs 35% of all members, P = 0.003). Compared with physicians in general, physicians in Congress were more likely to be men (93% vs 70%, P = 0.009) and surgeons (26% vs 11%, P = 0.01). Physician representation in Congress has increased substantially since 2000, potentially reflecting the greater political prominence of healthcare issues, as well as increased interest by and recruitment of physician-candidates. Physicians in Congress differ from their colleagues and from physicians in general in various demographic and political characteristics.

The temperature dependence of the infrared luminescence of a fluorotellurite glass doped with 0.01 and 2.5 mol% of Nd{sup 3+} ions was studied in order to use it as a high temperature sensing probe. For this purpose, the emission intensities of the ({sup 4}S{sub 3/2}, {sup 4}F{sub 7/2}), ({sup 2}H{sub 9/2}, {sup 4}F{sub 5/2}),{sup 4}F{sub 3/2}→{sup 4}I{sub 9/2} transitions were measured in a wide range of temperatures from 300 upto 650 K. The changes in the emission profiles were calibrated by means of the fluorescence intensity ratio technique. The calibrations showed a strong dependence on the Nd{sup 3+} ions concentration, having the low-doped concentrated sample the best response to changes of temperature. The maximum value obtained for the thermal sensibility is 17×10{sup −4} K{sup −1} at 640 K, being one of the highest values found in the literature for Nd{sup 3+} optical temperature sensors. Finally, the experimental calibrations were compared with the theoretical temperature luminescence response calculated from the Judd–Ofelt theory. - Highlights: • Nd{sup 3+}-doped fluorotellurite glasses were prepared. • The intensities of the ({sup 4}S{sub 3/2},{sup 4}F{sub 7/2}),({sup 2}H{sub 9/2},{sup 4}F{sub 5/2}), {sup 4}F{sub 3/2}→{sup 4}I{sub 9/2} transitions. • The highest thermal sensitivity has been obtained for the glass with the lowest concentration of Nd{sup 3+} ions. • The Nd{sup 3+}-doped fluorotellurite glass fits the requirement for a good temperature sensor.

The emission spectrum of neodymium produced by vacuum spark sources was observed in the vacuum ultraviolet on two normal-incidence spectrographs. In an initial result, more than 550 lines have been identified as transitions from 85 4f 2 5d levels to 37 levels of the 4f 3 ground configuration in the free ion Nd 3+ . The levels 4f 34 F 3/2 and 4 I 11/2 , responsible for the well-known 1064 nm laser line, have respective positions of 11 698.57 ±0.1 cm -1 and 1897.07 ±0.1 cm -1 above the ground level 4 I 9/2 . The newly found levels of 4f 3 constitute the first isolated 4f N configuration (N > 2) and therefore enable checks of effective parameters that represent far configuration interaction. Slater parameters F k (4f, 4f) derived from Nd 3+ :LaCl 3 are 3% to 5% smaller than in the free ion. (letter to the editor)

146Sm-142Nd systematics measured in enstatite chondrites reveals a heterogeneous distribution of 142Nd in the solar nebula.

The short-lived (146)Sm-(142)Nd chronometer (T(1/2) = 103 Ma) is used to constrain the early silicate evolution of planetary bodies. The composition of bulk terrestrial planets is then considered to be similar to that of primitive chondrites that represent the building blocks of rocky planets. However for many elements chondrites preserve small isotope differences. In this case it is not always clear to what extent these variations reflect the isotope heterogeneity of the protosolar nebula rather than being produced by the decay of parent isotopes. Here we present Sm-Nd isotopes data measured in a comprehensive suite of enstatite chondrites (EC). The EC preserve (142)Nd/(144)Nd ratios that range from those of ordinary chondrites to values similar to terrestrial samples. The EC having terrestrial (142)Nd/(144)Nd ratios are also characterized by small (144)Sm excesses, which is a pure p-process nuclide. The correlation between (144)Sm and (142)Nd for chondrites may indicate a heterogeneous distribution in the solar nebula of p-process matter synthesized in supernovae. However to explain the difference in (142)Nd/(144)Nd ratios, 20% of the p-process contribution to (142)Nd is required, at odds with the value of 4% currently proposed in stellar models. This study highlights the necessity of obtaining high-precision (144)Sm measurements to interpret properly measured (142)Nd signatures. Another explanation could be that the chondrites sample material formed in different pulses of the lifetime of asymptotic giant branch stars. Then the isotope signature measured in SiC presolar would not represent the unique s-process signature of the material present in the solar nebula during accretion.

The World Congress of Paediatric Cardiology and Cardiac Surgery: "The Olympics of our profession".

Science.gov (United States)

Hugo-Hamman, Christopher; Jacobs, Jeffery Phillip

2012-12-01

The first World Congress of Paediatric Cardiology was held in London, United Kingdom, in 1980, organised by Dr. Jane Somerville and Prof. Fergus Macartney. The idea was that of Jane Somerville, who worked with enormous energy and enthusiasm to bring together paediatric cardiologists and surgeons from around the world. The 2nd World Congress of Paediatric Cardiology took place in New York in 1985, organised by Bill Rashkind, Mary Ellen Engle, and Eugene Doyle. The 3rd World Congress of Paediatric Cardiology was held in Bangkok, Thailand, in 1989, organised by Chompol Vongraprateep. Although cardiac surgeons were heavily involved in these early meetings, a separate World Congress of Paediatric Cardiac Surgery was held in Bergamo, Italy, in 1988, organised by Lucio Parenzan. Thereafter, it was recognised that surgeons and cardiologists working on the same problems and driven by a desire to help children should really rather meet together. A momentous decision was taken to initiate a Joint World Congress of Paediatric Cardiology and Cardiac Surgery. A steering committee was established with membership comprising the main organisers of the four separate previous Congresses, and additional members were recruited in an effort to achieve numerical equality of cardiologists and surgeons and a broad geographical representation. The historic 1st "World Congress of Paediatric Cardiology and Cardiac Surgery" took place in Paris in June, 1993, organised by Jean Kachaner.

Full Text Available This paper offers a new perspective around the perception of political legitimacy held by the representatives to one of the most emblematic assemblies in Mexico. Reviewing the credentials of the Querétaro Constituent Congress allows us to observe the first internal disputes within constitutionalism, since plenty has been said about the enactment of the Political Constitution of the Mexican United States, whereas the legislative sessions that gave rise to it are not studied enough.  By presenting the chiaroscuros of the constituent parliamentary work, particularly during the first days of the electoral college, this article aims to complement the existing enormous historiographic production on this Congress.

Full Text Available The congress industry, as a part of business tourism sector, is globally recognized for its valuable economic contribution to tourism destinations. Regardless economic benefits, there are as well as numerous social, cultural and environmental benefits that congress industry brings to destinations. This is the reason why the congress industry is becoming one of the fastest growing sectors of tourism industry. At the same time, the congress destinations worldwide are competing in bidding international congresses. According to the Strategy of Tourism Development of the Republic of Serbia (2005, congress tourism is recognized as a quick win product that could contribute in a short period of 3 to 5 years to tourism development and image of Serbia. The cities of Belgrade, Novi Sad and Niš are identified as the congress destinations capable for hosting international congresses. Novi Sad, as administrative, economic, cultural, scientific and educational centre of the region of Vojvodina (northern part of Serbia and known as 'town of fairs'(it has long tradition in organizing fairs - since 1923 has strong potential for smaller international congresses. In order to improve quality of 'congress' tourist product, provide stability of congress destination and congress centers, it is necessary to understand meeting planners' and congress attendees' levels of satisfaction and reaction to their experience in destination. In Serbia there is no research regarding mentioned items. The aim of this paper is to examine and analyze the perspective of the congress attendees, as they are final consumers of congress tourist product and their experience and behavioural intentions regarding Novi Sad is thus essential to destination marketing and management organizations, congress centre, hotel managers and meeting planners. .

In the present study, the texturing of bulk α-Fe/Nd 2 Fe 14 B nanocomposites produced from Nd-lean amorphous Nd x Fe 92.5−x Cu 1.5 B 6 (x=9 to 11.5 at%) via a hot deformation under a uniaxial stress of ∼350 MPa at 973 K has been studied. An enhanced (00l) texture of the hard phase is observed with increasing Nd content, which results in an increase in the magnetic anisotropy of the nanocomposite magnets. As a result, both the coercivity and the remanence of the magnets increase simultaneously with increasing Nd content from x=9–11.5 at%, yielding a significant enhancement of the maximum energy product from (BH) max =13.2 to 17.5 MGOe in the direction parallel to stress axis. - Highlights: • Textured bulk α-Fe/Nd 2 Fe 14 B nanocomposites have been produced from Nd-lean alloys. • Nd content has an effect on the texturing of α-Fe/Nd 2 Fe 14 B nanocomposite magnets. • An enhanced (00l) texture of hard phase is observed with increasing Nd content. • Both the coercivity and remanence increase simultaneously with Nd content

2011-10-01

Early in 2005, the American Ceramic Society, the European Ceramic Society and the Ceramic Society of Japan announced a collaborative effort to provide leadership for the global ceramics community that would facilitate the use of ceramic and glass materials. That effort resulted in an agreement to organize a new biennial series of the International Congress on Ceramics, convened by the International Ceramic Federation (ICF). In order to share ideas and visions of the future for ceramic and glass materials, the 1st International Congress on Ceramics (ICC1) was held in Canada, 2006, under the organization of the American Ceramic Society, and the 2nd Congress (ICC2) was held in Italy, 2008, hosted by the European Ceramic Society. Organized by the Ceramic Society of Japan, the 3rd Congress (ICC3) was held in Osaka, Japan, 14-18 November 2010. Incorporating the 23rd Fall Meeting of the Ceramic Society of Japan and the 20th Iketani Conference, ICC3 was also co-organized by the Iketani Science and Technology Foundation, and was endorsed and supported by ICF, Asia-Oceania Ceramic Federation (AOCF) as well as many other organizations. Following the style of the previous two successful Congresses, the program was designed to advance ceramic and glass technologies to the next generation through discussion of the most recent advances and future perspectives, and to engage the worldwide ceramics community in a collective effort to expand the use of these materials in both conventional as well as new and exciting applications. ICC3 consisted of 22 voluntarily organized symposia in the most topical and essential themes of ceramic and glass materials, including Characterization, design and processing technologies Electro, magnetic and optical ceramics and devices Energy and environment related ceramics and systems Bio-ceramics and bio-technologies Ceramics for advanced industry and safety society Innovation in traditional ceramics It also contained the Plenary Session and the

2015-03-01

Full Text Available The 5th American Rabbit Congress was held in Toluca, Mexico State, Mexico from September 8th to the 11th, 2014. Research works representing 14 countries were accepted to take part at the congress, including papers from Algeria, Argentina, Brazil, China, Costa Rica, Cuba, Egypt, France, Hungary, Italy, México, Uruguay, the USA and Venezuela. These research works highlight the enormous interest, effort and commitment of the scientific community that bonds the trinomium of Research+Innovation+Technology Transfer, in favour of the integral development of rabbit rearing as an important primary activity that generates permanent employment, as well as healthy and nutritive meals for their respective countries for the XXI Century World. One major impact at this 5th American Rabbit Congress was the participation of Argentina, Brazil and China. The latter country’s report was presented by Laping Wu and Dong Wang (2014, showing that from 2005 to 2010, meat production of swine, beef and poultry underwent average growth of 2.6%, whereas rabbit meat production reported an annual average growth of 6.29%, reaching an annual volume of 761 000 tons, positioning China as the world’s main rabbit meat producer. This data highlights the great potential of rabbit production, both as an economic activity and a key strategy in the fight against hunger and poverty in many countries all over the world. During the congress, scientific works were presented related with the fields of Ethology, Housing & Welfare; Genetics; Reproduction; Digestive Physiology and Basic Nutrition; Feed Evaluation and Feeding; Pathology & Hygiene, Meat Quality, Safety & Dining; Management, Social & Economy. Furthermore, the meeting of the AB-WRSA chaired by the AB-WRSA founder, Dr. Steven Lukefahr, also took place at this congress, in which the new board of the American Branch was elected and the proposal put forward for the next American Rabbit Congress to be held in Costa

New England's dependence on oil (about 80%) is posing a double threat to the region and its economic prosperity, as oil dependency means extreme supply vulnerability and substantially higher prices than the national average. The New England Energy Congress, sponsored by the New England Congressional Caucus and Tufts Univ., represents the concerted effort of a highly diverse group of New Englanders to address these problems. The work of the six committees of the Congress is reviewed in this report. The committees are the Supply Committee, Energy Demand Committee, Energy Conservation Committee, Regulatory and Institutional Processes Committee, Economic Development through Alternative Sources of Energy Committee, and Energy Economics and Financing Committee.

The 2017 Seventh World Congress of Paediatric Cardiology and Cardiac Surgery: "The Olympics of our Profession".

Cohen, Mitchell I; Jacobs, Jeffrey P; Cicek, Sertac

2017-12-01

The 1st World Congress of Paediatric Cardiology was held in London, United Kingdom, in 1980, organised by Dr Jane Somerville and Prof. Fergus Macartney. The idea was that of Jane Somerville, who worked with enormous energy and enthusiasm to bring together paediatric cardiologists and surgeons from around the world. The 2nd World Congress of Paediatric Cardiology took place in New York in 1985, organised by Bill Rashkind, Mary Ellen Engle, and Eugene Doyle. The 3rd World Congress of Paediatric Cardiology was held in Bangkok, Thailand, in 1989, organised by Chompol Vongraprateep. Although cardiac surgeons were heavily involved in these early meetings, a separate World Congress of Paediatric Cardiac Surgery was held in Bergamo, Italy, in 1988, organised by Lucio Parenzan. Thereafter, it was recognised that surgeons and cardiologists working on the same problems and driven by a desire to help children would really rather meet together. A momentous decision was taken to initiate a Joint World Congress of Paediatric Cardiology and Cardiac Surgery. A steering committee was established with membership comprising the main organisers of the four separate previous Congresses and additional members were recruited in an effort to achieve numerical equality of cardiologists and surgeons and a broad geographical representation. The historic 1st "World Congress of Paediatric Cardiology and Cardiac Surgery" took place in Paris in June, 1993, organised by Jean Kachaner. The next was to be held in Japan, but the catastrophic Kobe earthquake in 1995 forced relocation to Hawaii in 1997. Then followed Toronto, Canada, 2001, organised by Bill Williams and Lee Benson; Buenos Aires, Argentina, 2005, organised by Horatio Capelli and Guillermo Kreutzer; Cairns, Australia, 2009, organised by Jim Wilkinson; Cape Town, South Africa, 2013, organised by Christopher Hugo-Hamman; and Barcelona, Spain, 2017, organised by Sertac Cicek.

Report explores Congress' science policy

Science.gov (United States)

Jones, Richard

Scientists interested in understanding how Congress develops science policy would find it useful to read a recent report by the Carnegie Commission on Science, Technology, and Government. “Science, Technology and Congress: Analysis and Advice from the Congressional Support Agencies” contains revealing insights about the often hard-pressed system that Congress uses to analyze science and technology issues.“Congress is on the front line of many battles over the directions of science and technology,” says the 70-page report. “The quality of congressional decisions on these issues often depends on the quality and usefulness of information and analysis made available to Congress.” The report describes the overwhelming amount of information received by members of Congress, few of whom have “substantial training or experience” in science and technology. Making this information understandable and useful is the role of the Office of Technology Assessment, the Congressional Research Service, the General Accounting Office, and the Congressional Budget Office.

Anon.

1986-01-01

Witnesses addressing the implications of expanding US nuclear trade with China included representatives of DOE, the Office of Technology Assessment, the Departments of State and Commerce, Library of Congress, and the Arms Control Agency. The purpose of the hearing was to seek a balanced approach between those who see expanded nuclear trade as a solution to the malaise of the US nuclear industry and the US balance of payments deficit and those who project the potential market at only five reactors at three sites. Among the topics raised were safeguards agreements and the impact on non-proliferation policy, the legal aspects of a nuclear cooperation agreement, and the possibility that nuclear trade might open up other areas for cooperation and trade. Additional material submitted by DOE, the State Department, and the Library of Congress follows the testimony of the 11 witnesses

The β-decay of 59 151 Pr 92 to the levels in 60 151 Nd 91 has been studied from the fission products of 235 U using an on-line isotope separator (KUR-ISOL). Gamma-rays and conversion electrons have been measured. Conversion coefficients have been determined for the first time. The precise decay scheme is proposed up to 2430 keV. The newly observed 65 γ-rays and 16 levels are incorporated in it. The deduced level scheme of 151 Nd was compared to the calculated level scheme on the basis of the rotation-vibration coupling model with a Nilsson potential. Low-lying levels were well reproduced by this model. (author)

Effects of neodymium concentration on optical characteristics of polycrystalline Nd:YAG laser materials

International Nuclear Information System (INIS)

Ikesue, A.; Kamata, K.; Yoshida, K.

1996-01-01

A neodymium-doped yttrium-aluminum garnet (Y 3 Al 5 O 12 , YAG) (Nd:YAG) ceramic that contained 0.3--4.8 at.% neodymium additives and exhibited nearly the same optical properties as those of a single crystal was fabricated by a solid-state reaction method using high-purity powders. Although the integrated absorption intensity of the 2 H 9/2 + 4 F 5/2 bands simply increased as the neodymium concentration in the YAG ceramics decreased, the fluorescence intensity of the 2.4 at.% Nd:YAG ceramic was the strongest among Nd:YAG ceramics with various neodymium concentrations and a 0.9 at.% Nd:YAG single crystal. An oscillation experiment was performed on a continuous-wave (cw) laser with a diode-laser exciting system using those ceramics and the single crystal. The oscillation threshold and slope efficiency in that analysis were 309 mW and 28%, respectively, for the 1.1 at.% Nd:YAG ceramics and 356 mW and 40%, respectively, for the 2.4 at.% Nd:YAG ceramics. The lasing characteristics of the ceramics in the present work were superior to those of a 0.9 at.% Nd:YAG single crystal that was fabricated by the Czochralski (Cz) method

First Mayan Women's Congress.

Teissedre, S

1997-01-01

In October 1997, over 200 participants attended the First Mayan Women's Congress in Mexico and called for financial assistance, capacity building, and training to help Mayan women escape poverty. The Congress was initiated by the UN Development Fund for Women in collaboration with the Small Grants Program of the UN Development Program. Traditionally, Mayan women and men have played distinct roles in society, and efforts are underway to increase gender sensitivity and achieve a new balance of power. Mayan women attending the Congress reported that they face daily challenges in gaining their husbands' approval for participation in income-generating activities outside of the home. Eventually, however, some husbands also start working in these enterprises and are learning to assume their share of domestic responsibilities. Mayan women have been forced to reevaluation their role in society by a prevailing agricultural and environmental crisis as well as a high unemployment rate. Crafts that were once produced only for household consumption are now considered for export. Because the women need funds to initiate income-generating activities, the Conference linked women's groups with development practitioners, policy-makers, and donors. The women requested financial aid for more than 30 specific projects, and Congress participants agreed to pursue innovate strategies to support the enterprises with funds, training, and technical assistance. The Congress also encouraged environmental nongovernmental organizations to include Mayan women in mainstream development activities. This successful Congress will be duplicated in other Mexican states.

This paper reports on the cathodoluminescence (CL) emission of both natural and synthetic lanthanide-rich phosphates (Ln3+: Ce, Nd) previously characterized by X-ray Diffraction (XRD), Environmental Scanning Electronic Microscopy (ESEM) and Energy Dispersive Spectroscopy. The thermal treatment at 700 °C performed on the synthetic sample obtained by chemical precipitation, promotes increasing of the crystallinity degree giving rise to a phase transition from the hexagonal (comprising monazite and rabdophane) into the monoclinic (cerianite and monazite) structures detected by XRD. Despite the size and the morphology of the grains are similar under ESEM, it could be appreciated significant differences among CL signals attending to the shape (with well-defined peaks for the annealed sample) and intensity (with lower emission for the non-thermally pretreated synthetic phosphate). The main wavebands centered at (i) 360, 380 and 490 nm are associated respectively with 5D3/2 → 2F5/2 and 5D3/2 → 2F7/2 transitions as well as a redox reaction assigned to the presence of Ce3+, (ii) 276, 424, 516 and 531 nm are linked respectively to 2G9/2→4I9/2, 2P1/2→4I9/2, 4G9/2→4I9/2 and 4G7/2→4I9/2 Nd3+ transitions and (iii) 400-490 nm is due to non-bridging oxygen hole centers related to the tetrahedral PO43- groups or structural defects for the heated synthetic samples. The natural sample from Madagascar, with a very complex CL spectrum, displays a characteristic band emission in the green-yellow and red regions corresponding to [UO2]2+ groups and Sm3+ respectively.

The enthalpy increments and the standard molar Gibbs energy of formation of NdFeO3(s) have been measured using a high-temperature Calvet microcalorimeter and a solid oxide galvanic cell, respectively. A λ-type transition, related to magnetic order-disorder transformation (antiferromagnetic to paramagnetic), is apparent from the heat capacity data at ∼687 K. Enthalpy increments, except in the vicinity of transition, can be represented by a polynomial expression: {H°m(T)-H°m(298.15 K)}/J·mol-1 (±0.7%)=-53625.6+146.0(T/K) +1.150×10-4(T/K)2 +3.007×106(T/K)-1; (298.15≤T/K ≤1000). The heat capacity, the first differential of {H°m(T)-H°m(298.15 K)} with respect to temperature, is given by Cop, m/J·K-1·mol-1=146.0+2.30×10-4(T/K)-3.007×106(T/K)-2. The reversible emf's of the cell, (-) Pt/{NdFeO3(s) +Nd2O3(s)+Fe(s)}//YDT/CSZ//{Fe(s)'FeO'(s)}/Pt(+), were measured in the temperature range from 1004 to 1208 K. It can be represented within experimental error by a linear equation: E/V:(0.1418±0.0003)-(3.890±0.023)×10-5(T/K). The Gibbs energy of formation of solid NdFeO3 calculated by the least-squares regression analysis of the data obtained in the present study, and data for Fe0.95O and Nd2O3 from the literature, is given by ΔfG°m(NdFeO3, s)/kJ·mol-1(±2.0)=-1345.9+0.2542(T/K); (1000≤T/K ≤1650). The error in ΔfG°m(NdFeO3, s, T) includes the standard deviation in emf and the uncertainty in the data taken from the literature. Values of ΔfH°m(NdFeO3, s, 298.15 K) and S°m(NdFeO3, s, 298.15 K) calculated by the second law method are -1362.5 (±6) kJ·mol-1 and 123.9 (±2.5) J·K-1·mol-1, respectively. Based on the thermodynamic information, an oxygen potential diagram for the system Nd-Fe-O was developed at 1350 K.

Special Issue of the Materials of the V International Congress on Energy Fluxes and Radiation Effects (Tomsk, Russia, 2016)Maksim Trigub, Georgiy Osokin, Alexander KonovodNational Research Tomsk Polytechnic University, 30, Lenin Avenue, Tomsk, Russiaemail: geosokin@tpu.ruThe present issue of the journal is based on the materials of the V International Congress on Energy Fluxes and Radiation Effects 2016 (EFRE 2016) that was held on October 2 to 7, 2016 in Tomsk (Russia). This large scientific forum gathers together scientists, developers and representatives of knowledge-intensive enterprises that have relevance to physics and technology. This year, the Congress was dedicated to the 120 th anniversary of the National Research Tomsk Polytechnic University.The history of the Congress as a joint scientific event dates back to 2000; it traditionally includes three conferences: International Symposium on High-Current Electronics (SHCE), International Conference on Radiation Physics and Chemistry of Condensed Matter (RPC) and International Conference on Modification of Materials with Particle Beams and Plasma Flows (CMM). However, each of these large conferences has its own lasting history.In 2016, the International Symposium on High-Current Electronics was arranged for the 19 th time. The participants have presented the results of fundamental studies and applied outcomes in the fields of high-power pulsed energy engineering and electronics (Pulsed Power), physics and application of high-power electron and ion beams, high- and low-temperature gas discharge plasma, physics of high-energy treatment and extreme states of matter, electric pulsed technologies. Noteworthy, the symposium took place in the year of the 40 th anniversary of USSR scientific discovery of explosive electron emission. This physical phenomenon—being one of the basics of high-current electronics—determines the processes in pulsed vacuum discharge, enables the operation of high-current electron

The sustainable society requires the recycling of rare metals. Rare earth Nd is one of rare metals, accompanying huge consumption especially in Nd-Fe-B magnets. Although the wet process using acid is in practical use in the in-plant recycle of sludge, higher selectivity between Nd and Fe at room temperature is desired. We have proposed a pretreatment of corrosion before the dissolution into HCl and the oxalic acid precipitation. The corrosion produces γ-FeOOH and a Nd hydroxide, which have high selectivity for HCl solution at room temperature. Nd can be recovered as Mn{sub 2}O{sub 3}-type Nd{sub 2}O{sub 3}. The estimated recovery-ratio of Nd reaches to 97%.

Values of the ratio of the reduced activation resonance integral to the thermal cross section, I'/σ 0 of 146 Nd, 148 Nd and 150 Nd were determined relative to gold by measuring cadmium ratios. A lithium-drifted germanium gamma ray spectrometer was used to resolve the activities of the irradiated samples. The results are for 146 Nd I'/σ 0 = 1.42±0.1 0 and with an assumed σ 0 = 1.4 barn, I' = 1 .99±0.20; for 148 Nd I'/ σ 0 = 4.22±0.1 4 and with an assumed σ 0 = 2.5 barn, I' = 10.5±0. 9 barn, and for 150 Nd I'/σ 0 = 13.7±0. 8 and with an assumed σ 0 = 1.2 barn, I' = 16.4±2.8. The resolved and unresolved epithermal integrals of 146 Nd, 148 Nd and 150 Nd were calculated. Values of the spectral correction factor were also calculated, so the resonance integral could be obtained from the epithermal integral data measured in our reactor spectrum in this experiment. Epithermal integral and spectral correction factors are listed in the text. The most important result of this investigation is that the 148 Nd activation reduced resonance integral is about half of the previously recommended value and consequently the radiative width for 148 Nd is also about half of the previously accepted value.

Authors here report the dual mode photo luminescence emission in neodymium doped yttrium oxide ceramic phosphor upon 808 nm diode laser excitation. Single cubic phase Nd{sup 3+} doped Y{sub 2}O{sub 3} phosphor was synthesized using urea assisted combustion route. Nd{sup 3+} doped Y{sub 2}O{sub 3} ceramic phosphor has given photoluminescence in a wide wavelength range covering near infrared window (850–1100 nm) to the visible region i.e. green (525 nm) and red (680 nm) upon 808 nm diode laser excitation. The two most intense bands on 808 nm excitation were observed at 750 nm and 1064 nm due to the upconversion and downconversion emission processes. The sample was also tested for emission using 980 nm and intense green emission due to the trace presence of Er{sup 3+} in the raw materials was seen in the sample. The excitation power dependent upconversion measurements have shown that transitions {sup 4}F{sub 9/2}→{sup 4}I{sub 9/2} and {sup 4}S{sub 3/2}→{sup 4}I{sub 9/2} are thermally coupled and can be used to estimate the sample temperature using Boltzmann relation.

Propagation of Nd magnetic phases in Nd/Sm(001) superlattices

International Nuclear Information System (INIS)

Soriano, S; Dufour, C; Dumesnil, K; Stunault, A

2006-01-01

The propagation of Nd long range magnetic order in the hexagonal and cubic sublattices has been investigated in double hexagonal compact Nd/Sm(001) superlattices by resonant x-ray magnetic scattering at the Nd L 2 absorption edge. For a superlattice with 3.7 nm thick Sm layers, the magnetic structure of the hexagonal sublattice propagates coherently through several bilayers, whereas the order in the cubic sublattice remains confined to single Nd blocks. For a superlattice with 1.4 nm thick Sm layers, the magnetic structures of both sublattices appear to propagate coherently through the superlattice. This is the first observation (i) of the long range coherent propagation of Nd order on the cubic sites between Nd blocks and (ii) of a different thickness dependence of the propagation of the Nd magnetic phases associated with the hexagonal and cubic sublattices. The propagation of the Nd magnetic order through Sm is interpreted in terms of generalized susceptibility of the Nd conduction electrons

Optical spectroscopy in channel waveguides made in Nd:YAG crystals by femtosecond laser writing

International Nuclear Information System (INIS)

Torchia, G.A.; Mendez, C.; Roso, L.; Tocho, J.O.

2008-01-01

In this work, we present an optical characterization of channel waveguides fabricated by means of femtosecond laser writing on Nd:YAG substrates. These guiding structures show a refractive index increment of about 1x10 -3 which allows TE propagation. By pumping with a CW solid-state laser at 532 nm reaching the 2 G 9/2 and 4 G 7/2 manifolds of Nd 3+ ions, we have explored the emission band corresponding to 4 F 3/2 → 4 I 9/2 optical transitions (peaked at 890 nm). From data, we have found that emission showed similar characteristics for waveguide and bulk. On the other hand, the lifetime corresponding to the 4 F 3/2 metaestable level was determined to be 240 μs for bulk and waveguide. Summarizing, we have made suitable channel waveguides in Nd:YAG crystals, by fs interaction, with similar spectroscopic properties to those of the bulk, a fact that boosters the photonics application of these devices. For the first time to our knowledge, a direct index increment waveguide made by interaction with ultra-short intense pulses in YAG crystals has been performed. This fabrication procedure can be an efficient tool to make several optical circuits in active materials by means of the one-step, fast and low-cost processing

Discourse and dissonance: religious agendas in the 104th Congress

Directory of Open Access Journals (Sweden)

Bethany Blackstone

2015-07-01

Full Text Available This paper investigates the religious dimension of Republican legislators’ participation in one-minute speeches during the 104th Congress (1995–1996. Many have characterized the House Republican Conference that emerged after the 1994 elections as a highly cohesive majority party. Even in that context, however, legislators represent varied personal agendas, and in part these are informed by religion. We topically coded a subset of floor speeches to measure the extent to which variation is observed in the issues addressed by Members of Congress. The findings demonstrate that on key policy domains, such as the role of government, culture, and social welfare, speech participation varies systematically on the basis of member religion. This suggests that legislative participation is influenced by genuine personal preferences in additional to strategic political factors.

Graphical abstract: Relative density enhancement and nanocrystallization of Nd{sub 2}Fe{sub 14}B phase are two major effective means to improve magnetic properties. Since the matrix Nd{sub 2}Fe{sub 14}B phase in the starting Nd-Fe-B alloy can be disproportionated into a nano-structured mixture of NdH{sub 2.7}, Fe{sub 2}B, and {alpha}-Fe phases during mechanical milling in hydrogen. It is thus important to study the densification behavior of nanocrystalline powders to evaluate and predict the cold compactibility of powders. By comparison with the as milled as well as melt-spun Nd{sub 16}Fe{sub 76}B{sub 8} alloy powders, we find that the as-disproportionated Nd{sub 16}Fe{sub 76}B{sub 8} alloy powder exhibits the best cold compactibility. As evident from the illustration presented below, compaction parameters (representing the powder compactibility) have been determined by fitting density-pressure data with double logarithm compaction equation. Densification mechanisms involved during cold compaction process are clarified in our work by referring to microstructure observation of samples prepared by various methods. As a result, highly densified green magnet compact can be obtained by cold pressing of as-disproportionated NdFeB alloy powders.

The composite magnet NdFeB has been made using magnetic powder MQP-B and polyvinyl alcohol (PVA) as the binder. The mixing compositions of raw materials used are: 95 wt% NdFeB - 5 wt% PVA, 92.5 wt% NdFeB - 7.5 wt% PVA, 90 wt.% NdFeB - 10 wt% PVA, and 87.5 wt% NdFeB - 12.5 wt% PVA. Both raw materials are weighed according to the composition, and then mixed until homogeneous. Furthermore, pellet forming was made using dry pressing at 50 kgf/cm2 pressures and continued with drying at 100 °C and 10 mmbar for 4 hours. The characterization includes bulk density, hardness, compressive strength measurements, and magnetic properties testing. The characterization results show that the optimal composition of binder PVA is achieved at 5–7.5 wt% NdFeB composite magnet with following properties: bulk density = 5.21–5.25 g/cm3, hardness = 302.17 - 304.32 Hv, compressive strength = 25.17–3.17 kgf/cm2, magnetic flux = 1150-1170 Gauss, remanence = 70.90–74.97 emu/g or 4.7–5.0 kGauss, coercivity = 8.68–8.76 kOe, and energy product = 2.89–3.04 MgOe.

Magnetoresistance in amorphous NdFeB/FeB compositionally modulated multilayers

International Nuclear Information System (INIS)

Peral, G.; Briones, F.; Vicent, J.L.

1991-01-01

Resistance measurements have been done in amorphous Nd 12 Fe 80 B 8 sputtered films and in amorphous sputtered Nd 26 Fe 68 B 6 /Fe 92 B 8 multilayers between 6 and 150 K with applied magnetic field parallel (LMR) and perpendicular (TMR) up to 7 T. The samples were grown by dc triode sputtering, with nominal unequal (2:1) layer thicknesses. The layered character of the samples have been tested by x-ray diffraction. Longitudinal magnetoresistance (LMR) is positive and transverse magnetoresistance (TMR) is negative. The magnetoresistance values are higher than in amorphous ferromagnets, and multilayering of these alloys produces much larger magnetoresistance values than either alloy alone and there is a strong dependence on the multilayer wavelength. The MR shows a weak temperature dependence in the temperature interval that was investigated

High Precision 142Nd/144Nd and 143Nd/144Nd Isotope Ratio Measurements in Rock Samples

Science.gov (United States)

Ali, A.; Srinivasan, G.

2009-05-01

The long-lived 147Sm-143Nd system with a half-life (T1/2) of 106 Gyr is generally used for geochronology. The short-lived 146Sm-142Nd system (T1/2= 103 Myr) is used as a geological tracer to track early (˜500 Ma) silicate differentiation [1] events in different planetary bodies. The isotope composition measurements by thermal ionization mass spectrometry (TIMS) require purification of Nd using chemical separation methods. This is important as an impure sample will give both a very poor ion yield and cause beam instability in the mass spectrometer, potentially resulting in a poor analysis [2]. The separation of Nd for 143Nd isotope measurement is, fairly straightforward because there is no isobaric interference of any other REE. While 142Nd isotope analysis needs chemically separated Nd fraction to be ˜100% Ce-free as latter is composed of a substantial amount of 142Ce isotope. A 4-steps technique, modified from Caro et al., [3], for the separation of Nd is established at the Cosmochemistry Laboratory of University of Toronto, Canada and applied to the measurement of Nd isotope ratios in geological reference sample BCR-2 (USGS, Columbia River basalt) using TIMS. Results of the isotopic ratios obtained for BCR-2 are in good agreement with published values [e.g., 4]. Analytical work on the samples discovered as the oldest rocks on Earth [5] from Nuvvuagittuq greenstone belt in Québec, Canada and various meteorites is in progress. An account of the procedures involved is briefly described here. All working solutions and acids were prepared using >18.2 MΩ.cm-1 H2O from a Milli-Q water system. Experiments were performed under Class 100 clean work bench with acid-cleaned apparatus and plastic-ware. The whole rock powders were weighed (20-30 mg) and dissolved in a mixture of HF and HNO3 using PFA vials and heated at 110°C. Further decomposition was done in Teflon bomb in the oven at 205°C. Later on contents of the Teflon bomb were transferred to vials and fluorides

To measure social network activity during the 81th National Congress of the Spanish Urological Association (AEU) and to compare it with the activity during other congresses of national and international urological associations. We designed and registered the official hashtag #AEU16 for the 81 th National Congress of the AEU on the Symplur website. The following measurements were recorded: number of participants, number of tweets, tweets by participant, tweets per hour and views. The number of participants in the social network activity during the congress was 207. The measurements of activity in Twitter consisted of a total of 1866 tweets, a mean rate of 16 tweets/h, 9 tweets per participant and 1,511,142 views. The activity during the international congresses is as follows: 2016 American Urological Association annual congress (views: 28,052,558), 2016 European Association of Urology annual congress (views: 13,915,994), 2016 Urological Society of Australia and New Zealand (views: 4,757,453), 2015 Société Internationale d'Urologie annual congress (views: 1,023,038). The activity during the national congresses was recorded as follows: 2016 Annual Conference of The British Association of Urological Surgeons (views: 2,518,880), 81th National Congress of the AEU (views: 1,511,142), 109th Congress of l'Association Française d'Urologie (views: 662,828), 67th German Congress of Urology (views: 167,347). We found 10 posts in Facebook and 2 communications via Periscope TV related to #AEU16.

2005-01-01

The 8th Congress of the Asia and Oceania Confederation of Nuclear Medicine and Biology opened at the old cultural city, Beijing on 9th October 2005. The main theme of the 8th Congress was 'Progress with time - to create a brilliant future'. The congress addressed most of the current trends, developments and achievements in the field of nuclear medicine in an extremely friendly and peaceful environment. Besides the main congress, a Pre-congress colloquium in Beijing by the World Radiopharmaceutical Therapy Council (on 9 October), and two post-congress Satellite meetings at Shanghai and Hong Kong on 15 and 17 October respectively were organized in conjunction with the 8th congress. One of the major achievements of the congress was a record number of 58 invited lectures delivered by a galaxy of internationally reputed professionals in nuclear medicine and allied sciences. Four hundred and fifty-six (456) participants, 230 of them from China and 226 from another 33 countries of Asia and from around the rest of the world; 23 exhibitors representing manufacturers and producers of nuclear medicine equipment, radiopharmaceuticals and consumables, participated in the congress. A total of 384 abstracts were received for presentation from 36 countries, 141 for oral and 243 for poster presentation. Majority of the abstracts came from Asia; significant numbers came from Australia, Europe and North America. The distribution of abstracts in terms of the topics is given. The most popular subject was nuclear oncology, followed by general nuclear medicine, nuclear cardiology, radionuclide therapy, nuclear neurology and radiopharmacy. As compared to the presentations at the 7th AOCNMB; it was observed that there has been increases in presentations on topic related to nuclear oncology, radionuclide therapy, basic nuclear medicine, radiopharmacy and instrumentation at the 8th Congress; whereas significant reduction was observed in the number of presentations related to general nuclear

Effects of thickness and annealing condition on magnetic properties and thermal stabilities of Ta/Nd/NdFeB/Nd/Ta sandwiched films

International Nuclear Information System (INIS)

Liu Wen-Feng; Zhang Min-Gang; Zhang Ke-Wei; Zhang Hai-Jie; Chai Yue-Sheng; Xu Xiao-Hong

2016-01-01

Ta/Nd/NdFeB/Nd/Ta sandwiched films are deposited by magnetron sputtering on Si (100) substrates, and subsequently annealed in vacuum at different temperatures for different time. It is found that both the thickness of NdFeB and Nd layer and the annealing condition can affect the magnetic properties of Ta/Nd/NdFeB/Nd/Ta films. Interestingly, the thickness and annealing temperature show the relevant behaviors that can affect the magnetic properties of the film. The high coercivity of 24.1 kOe (1 Oe = 79.5775 A/m) and remanence ratio (remanent magnetization/saturation magnetization) of 0.94 can be obtained in a Ta/Nd(250 nm)/NdFeB(600 nm)/Nd(250 nm)/Ta film annealed for 3 min at 1023 K. In addition, the thermal stability of the film is also linked to the thickness of NdFeB and Nd layer and the annealing temperature as well. The excellent thermal stability can be achieved in a Ta/Nd(250 nm)/NdFeB(600 nm)/Nd(250 nm)/Ta film annealed at 1023 K. (paper)

A route for recycling Nd from Nd-Fe-B magnets using Cu melts

Energy Technology Data Exchange (ETDEWEB)

Moore, Martina; Gebert, Annett, E-mail: a.gebert@ifw-dresden.de; Stoica, Mihai; Uhlemann, Margitta; Löser, Wolfgang

2015-10-25

Phase evolutions in Nd-Fe-B magnet/Cu systems have been explored with regard to Nd recycling. It was demonstrated that large scale phase separation into a ferromagnetic Fe(B)-rich ingot core with α-Fe main phase and a non-magnetic (Cu,Nd)-rich ingot rim takes place upon arc melting with Cu fractions ≥ 21.5 wt.-%. The re-solidification of the Nd{sub 2}Fe{sub 14}B magnet main phase is suppressed. The rim consists of the Cu{sub 2}Nd main phase and CuNd/Cu{sub 4}Nd minority phases in which Al traces from the magnetic material are gathered. Induction melting of such Nd-Fe-B/Cu mixtures can support the separation of these phase regions with very sharp boundaries. Main features of liquid phase separation and microstructure evolution have been interpreted on the basis of Nd-Fe-Cu phase diagram data. The key advantage with respect to Nd recycling from Nd-Fe-B permanent magnet scrap is the substantial accumulation of Nd in the (Cu,Nd)-rich region of the phase separated solidified specimen, which can be easily detached from the Fe-rich part by mechanical-magnetic treatments. Such portions contained up to ∼44 wt.-% Nd (25 at.-%) in first lab-scale experiments. Nd recovery from the (Cu,Nd)-rich fractions is possible by exploiting the large chemical property differences between the reactive rare earths elements and Cu. - Highlights: • phase evolution analysis in Nd-Fe-B magnet/Cu systems with regard to Nd recycling. • Cu ≥ 21 wt.-%, large scale phase separation- Fe(B)-rich ingot core, (Cu,Nd)-rich rim. • high Nd content (∼44 wt.-%) of (Cu,Nd)-rich region, mechanical-magnetic treatments.

Nd isotopes and crustal growth rate

International Nuclear Information System (INIS)

Albarede, F.

1988-01-01

Sm/Nd isotopic constraints on crustal growth is discussed. In order to constrain Sm/Nd fractionation between continental crust and depleted mantle, an extensive data base of isotopic measurements (assumed to be adequately representative of continental crust) was compiled. The results imply that the evolution of depleted mantles was roughly linear, with no major discontinuities over the course of geologic time. This is different from other determinations of depleting mantle evolution, which show nonlinear behavior. The Sm/Nd evolution lines for continental crust and depleted mantle intersect between 3.8 to 4.0 Ga, which may indicate that the onset of continental growth was later than 4.5 Ga. A mathematical model is described, the results of which imply that time integrated crustal additions from the mantle are about 1.8 to 2.5 cu km/a, whereas crustal subtractions by sediment recycling are about 0.6 to 1.5 cu km/a. This results in a net time integrated crustal growth rate of about 1 cu km/a, which is similar to present day rates determined, for example, by Reymer and Schubert

Preventing nuclear explosive testing. Submitted to the House of Representatives, Ninety-Ninth Congress, First Session

International Nuclear Information System (INIS)

Anon.

1985-01-01

H.J. Resolution 3 banning the testing of nuclear weapons over 150 kilotons seeks to slow the arms race by urging Congress to ratify the 1974 Threshold Test Ban Treaty and the 1976 Peaceful Nuclear Explosions Treaty and urging the President to resume negotiations with the Soviet Union. The House Foreign Affairs Committee report supports the concept after a series of hearings with verification experts and the weapons and intelligence establishments. Verification and weapons reliability were the key issues of concern, but the committee concluded that politics rather than technology prevented a comprehensive test ban. The report also includes the reminder in the minority view that talks were suspended after the Soviet invasion of Afghanistan and that scientists need further testing to make weapons safer and less vulnerable to terrorist action

Single crystals of Nd{sup 3+}-doped Co-picromerite has been synthesized by the slow evaporation method. After two weeks on hold, the crystals obtained were characterized by different techniques, indeed X-ray powder diffraction (XRPD) shows that these compounds crystallize in the monoclinic system with space group P21/a. Complete dehydration of the double salt was obtained before reaching 200 °C with a phase transition of KS around 570 °C. The IR spectroscopic study confirms the vibrational modes of the sulfate groups and water molecules. Exciting at 473 nm, the emission peaks associated with the 4F{sub 5/2}→4I{sub 9/2}, 4F{sub 3/2}→4I{sub 9/2} and 4F{sub 3/2}→4I{sub 11/2} transitions were observed. The luminescence decay curve was analyzed in the frame of the Inokuti-Hirayama model in order to obtain the intrinsic lifetime and the energy transfer parameter among Nd{sup 3+}ions.

Structural and magnetic characterization of Nd-based Nd-Fe and Nd-Fe-Co-Al metastable alloys

International Nuclear Information System (INIS)

Kumar, G.

2005-01-01

The aim of the present work is to characterize a metastable hard magnetic phase referred to as ''A1'' in Nd-Fe alloys, which forms as a part of the fine eutectic depending on the composition and cooling rate. In order to define the range of composition for the formation of A1, Nd 100-x Fe x (x=20,25,40) alloys are cooled at about 150 K/s. The effect of cooling rate on the formation of hard magnetic A1 is studied by investigating the Nd 80 Fe 20 alloys cooled at different rates. The Nd-richer regions are identified as dhcp Nd and fcc Nd-Fe solid solution. However, the Fe-richer regions also referred to as A1, are diffuse and give an average composition of Nd 56 Fe 44 . HRTEM images of the Fe-richer regions reveal the presence of 5-10 nm crystallites embedded in an amorphous phase. The demagnetization curves the hard magnetic Nd80Fe20 measured at temperatures above 30 K are typical of a hard magnetic material. The measurements of initial magnetization, field dependence of coercivity, and temperature dependence of coercivity suggest the Stoner-Wohlfarth type magnetization reversal process for the hard magnetic A1. The values of anisotropy constant are estimated by fitting the magnetization data to the law-of-approach to saturation. The temperature dependence of anisotropy constant and the coercivity indicate that the origin of coercivity is magnetic anisotropy

Anomalous behavior of spin fluctuations in polycrystalline NdBa_2Cu_3O_7-δ

Science.gov (United States)

Abdelrazek, M. M.; Reyes, A. P.; Kuhns, P. L.; Moulton, W. G.; Halperin, W. P.; Kishio, K.

2001-03-01

Critical slowing down of Nd spin fluctuations have been observed in 92K superconductor NdBa_2Cu_3O_7-δ at temperatures well below Tc and orders of magnitude higher than TN ( ~0.5K). Nuclear spin-lattice relaxation rate 1/T1 at the planar O(2,3) and bridging O(4) oxygen sites have been measured as a function of temperature in fields up to 37T. Data is characterized by an extremely fast relaxation, roughly two orders of magnitude larger than those of YBCO, suggestive of Nd origin. The temperature dependence shows neither Tc nor the pseudo-gap but rather a well-defined field-dependent peak for both sites. Preliminary analysis suggests 1/T1 follows the typical behavior of freezing of spin fluctuations, when the inverse correlation time of the Nd spins τc becomes comparable to NMR frequency, ω τc ~ 1. The field dependence originates from the tail of the power spectrum beyond the 1/τc cutoff. The implications of these results to superconductivity in these systems will be discussed.

Gouteff, P.C.; Folks, L.; Street, R.

1998-01-01

Domain structures of NdFeB thin films, ranging in thickness between 1500 and 29 nm, have been studied qualitatively by magnetic force microscopy (MFM). Samples were prepared using a range of sputtering conditions resulting in differences in properties such as texture, coercivity and magnetic saturation. MFM images of all the films showed extensive interaction domain structures, similar to those observed in nanocrystalline bulk NdFeB. An exchange-coupled NdFeB/Fe/NdFeB trilayer with layer thicknesses 18 nm/15 nm/18 nm, respectively, was also examined using MFM. (orig.)

Mixing of the odd-parity excitations in Nd, Sm and Gd nuclei with 86 and 87 neutrons

1978-08-01

The low- and medium-spin structure of the four nuclei 148 Sm 86 , 147 Nd 87 , 149 Sm 87 and 151 Gd 87 has been investigated experimentally and theoretically. The low-spin states of 151 Gd were obtained in the EC and β + decay of 151 Tb. The proposed level scheme, based on gamma-gamma coincidence and conversion-electron measurements, contains several new energy levels, among them a 5/2 - state at 427 keV. Nanosecond lifetimes of the states in 147 Nd were studied using the reaction 146 Nd(d,pγ) 147 Nd with 10 MeV deuterons. The reactions sup(148,150)Nd( 3 He,xn) at Esup(3sub(He)) = 19 - 27 MeV were used to study excited states in the nuclei 148 Sm and 149 Sm. Gamma-ray excitation fuctions, angular and time distributions, gamma-gamma coincidences and conversion electrons were measured. The presence of the Z = 64 closed proton core is proposed to be important for the structure of the even and odd isotones considered. Calculations performed for 148 Sm using the interacting-boson-approximation model and related to the N = 82, Z = 64 and N = 82, Z = 50 cores are discussed. The properties of the negative-parity low-spin states of the N = 87 isotones are explained with an axial particle-plus-rotor model. The calculated B(M1) and B(E2) probabilities are compared with a compilation of experimental values. Most of the spectroscopic factors of 149 Sm are reproduced well in the calculation. The consequences of nonaxiality are discussed for the fsub(7/2)- and hsub(9/2)-based excitations. The standard Meyer-ter-Vehn model calculation indicates different asymmetries for the fsub(7/2) and hsub(9/2) shells. (author)

Ta/Nd/NdFeB/Nd/Ta sandwiched films are deposited by magnetron sputtering on Si (100) substrates, and subsequently annealed in vacuum at different temperatures for different time. It is found that both the thickness of NdFeB and Nd layer and the annealing condition can affect the magnetic properties of Ta/Nd/NdFeB/Nd/Ta films. Interestingly, the thickness and annealing temperature show the relevant behaviors that can affect the magnetic properties of the film. The high coercivity of 24.1 kOe (1 Oe = 79.5775 A/m) and remanence ratio (remanent magnetization/saturation magnetization) of 0.94 can be obtained in a Ta/Nd(250 nm)/NdFeB(600 nm)/Nd(250 nm)/Ta film annealed for 3 min at 1023 K. In addition, the thermal stability of the film is also linked to the thickness of NdFeB and Nd layer and the annealing temperature as well. The excellent thermal stability can be achieved in a Ta/Nd(250 nm)/NdFeB(600 nm)/Nd(250 nm)/Ta film annealed at 1023 K.

2017-01-01

Full Text Available Ta/Nd/NdFeB/Nd/Ta films were deposited by magnetron sputtering on Si (100 substrates and subsequently annealed for 30 min at 923 K in vacuum. It was found that the microstructure and magnetic properties of Ta/Nd/NdFeB/Nd/Ta films strongly depend on the NdFeB layer thickness. With NdFeB layer thickness increasing, both the grain size and the strain firstly reduce and then increase. When NdFeB layer thickness is 750 nm, the strain reaches the minimum value. Meanwhile, both the in-plane and perpendicular coercivities firstly drastically increase and then slowly decrease with NdFeB layer thickness increasing. The highest in-plane and perpendicular coercivities can be obtained at NdFeB layer thickness of 750 nm, which are 21.2 kOe and 19.5 kOe, respectively. In addition, the high remanence ratio (remanent magnetization/saturation magnetization of 0.87 can also be achieved in Ta/Nd/NdFeB (750 nm/Nd/Ta film.

For the first time cationic surfactant assisted ultrasound synthesis route has been used for the preparation of pure and Nd3+ (0.5-9 mol %) doped Zn2SiO4 nanophosphors. The shape, size and morphology of the products were tuned by controlling the various experimental parameters. The final product was well characterized by sophisticated techniques viz. powder X-ray diffraction (PXRD), Ultraviolet visible spectroscopy (UV-Vis) and photoluminescence (PL). The powder X-ray diffraction patterns confirmed that the synthesized samples exhibit hexagonal phase without any impurity. The DRS spectra showed major peaks at 275, 360, 529, 586, 680, 742 and 806 nm due to the transitions of the 4f electrons of Nd3+ from the ground-state 4I9/2 to 2F5/2, 4D3/2 + 4D5/2 + 2I11/2, 2K13/2 + 4G7/2 + 4G9/2, 4G5/2 + 2G7/2, 4F7/2 + 4S3/2, 4F5/2 + 2H9/2 and 4F3/2 respectively. The band energy gap (Eg) of the samples were estimated and found to be in the range 5.32 - 5.52 eV. Under 421 nm excitation, PL spectra exhibit strong near ultraviolet emission peaks at˜444 nm, 459 nm and 520 nm were attributed to 2P3/2 → 4I13/2, 2P3/2 → 4I15/2, 1I6 → 3H4, 2P1/2 → 4I9/2 and 4G7/2 → 4I9/2 transitions respectively. The photometric studies indicate that the synthesized Zn2SiO4: Nd3+ nanophosphors can be tuned from blue to pale green by varying the dopant concentration. The current synthesis route is rapid, environmentally benign, cost-effective and useful for industrial applications such as solid state lighting and display devices.

Rapid economical growth and expansion of human population have produced a number of environmental problems with varying geographic dimensions. While local problems remain near the pollution sources, the focus of the scientific community is more and more shifted towards regional, continental and global consequences of air pollutants. The theme of the 10th Clean Air Congress 'Growing Challenges from Local to Global' reflects the growing demand from the scientific and professional community working in air pollution prevention and environmental protection - more and more complex mechanisms should be understood on a growing spatial scale. The 10th World Clean Air Congress addresses in its more than 400 presentations, documented in three Volumes of Proceedings, the history, the present and the potential futures of the air pollution problems. Air has during different times always represented something valuable to people: the logo of the Congress, the octahedron sign, sympolizes the element of air in acient Greek philosophy. Today air quality is not only valued as important, it is a death serious matter. This Volume includes the presentations of the path A 'Emissions and Control' of the Congress. This path deals with issues related to measurement, monitoring and inventories of air pollutants from mobile and stationary sources, and the various ways to control the emissions of acidifying pollutants, air toxics and aerosols, volatile organic compounds, and odours. Integrated approaches to pollution prevention and non-waste technologies in various industrial sectors, have recently obtained special attention

Full Text Available The second ESMO Asia 2016 Congress, led by an international committee to promote the sharing of expertise and interaction between regional and international experts in oncology, returned for a second appearance at the Suntec Convention and Exhibition Centre in Singapore recently. Organized by the European Society for Medical Oncology (ESMO, the Asian leg of the annual scientific and educational congress was held from December 16–19th, 2016 and attended by over 2,000 healthcare professionals and exhibitors, including representatives from AMOR who were also present to cover the event. ESMO Asia 2016 brought together oncologists from the Asian region and beyond to discuss important discoveries in oncology and to update delegates on the latest standards of care, the organizer noted in its media release. More specifically, delegates attending the meeting took the opportunity to exchange thoughts and ideas on current clinical challenges and novel treatment strategies for a variety of tumor subtypes, as well as to highlight emerging cancer therapeutics that are rapidly gaining attention in clinical settings. In addition to highlighting the latest in cancer research, the congress also sought to underscore bioethical, economic, and social challenges posed by cancer by addressing crucial issues such as the rising costs of treatments, the need for psychological support for patients, the need for better palliative care, and the vital importance of improving access to innovative drugs. In this edition of the ESMO Asia congress, the keynote lectures consisted of two topics: how the differences between tumors can impact the design of effective treatments, and the link between common Epstein-Barr virus and nasopharyngeal cancer. With these two keynote lectures setting the tone for the congress, delegates saw a wide range of key discussions pertaining to the clinical relevance of molecular advances and innovative treatment approaches.

Polarized absorption spectra of single-crystal Nd 0.5 Gd 0.5 Fe 3 (BO 3 ) 4 were studied in the region of the transition 4 I 9/2 →( 4 G 5/2 + 2 G 7/2 ) in Nd 3+ ion as a function of temperature (2–34 K) and magnetic field (0–65 kOe). The spectra of natural circular dichroism were measured in the range of 5–40 K. It was found out that the local magnetic properties in the vicinity of the excited ion substantially depended on its state. In particular, a weak ferromagnetic moment appears in some excited states. It was found out that the selection rules for electron transitions in the magnetically ordered state substantially deviated from those in the paramagnetic state of the crystal. They are different for different transitions and they are very sensitive to the orientation of the sublattice magnetic moment relative to the light polarization. In the spectrum of the natural circular dichroism, the transition is revealed which is not observed in the absorption spectrum. - Highlights: • Temperature and field dependences of f-f transitions in Nd 0.5 Gd 0.5 Fe 3 (BO 3 ) 4 . • Natural circular dichroism in Nd 0.5 Gd 0.5 Fe 3 (BO 3 ) 4 below T N . • Weak ferromagnetic moment was identified in some excited 4f states. • Selection rules for f-f transitions substantially change below T N . • Intensities of f-f transitions strongly depend on magnetic moment orientation

(142)Nd evidence for an enriched Hadean reservoir in cratonic roots.

Science.gov (United States)

Upadhyay, Dewashish; Scherer, Erik E; Mezger, Klaus

2009-06-25

The isotope (146)Sm undergoes alpha-decay to (142)Nd, with a half-life of 103 million years. Measurable variations in the (142)Nd/(144)Nd values of rocks resulting from Sm-Nd fractionation could therefore only have been produced within about 400 million years of the Solar System's formation (that is, when (146)Sm was extant). The (142)Nd/(144)Nd compositions of terrestrial rocks are accordingly a sensitive monitor of the main silicate differentiation events that took place in the early Earth. High (142)Nd/(144)Nd values measured in some Archaean rocks from Greenland hint at the existence of an early incompatible-element-depleted mantle. Here we present measurements of low (142)Nd/(144)Nd values in 1.48-gigayear-(Gyr)-old lithospheric mantle-derived alkaline rocks from the Khariar nepheline syenite complex in southeastern India. These data suggest that a reservoir that was relatively enriched in incompatible elements formed at least 4.2 Gyr ago and traces of its isotopic signature persisted within the lithospheric root of the Bastar craton until at least 1.48 Gyr ago. These low (142)Nd/(144)Nd compositions may represent a diluted signature of a Hadean (4 to 4.57 Gyr ago) enriched reservoir that is characterized by even lower values. That no evidence of the early depleted mantle has been observed in rocks younger than 3.6 Gyr (refs 3, 4, 7) implies that such domains had effectively mixed back into the convecting mantle by then. In contrast, some early enriched components apparently escaped this fate. Thus, the mantle sampled by magmatism since 3.6 Gyr ago may be biased towards a depleted composition that would be balanced by relatively more enriched reservoirs that are 'hidden' in Hadean crust, the D'' layer of the lowermost mantle or, as we propose here, also within the roots of old cratons.

Random laser (RL) emission in Nd{sup 3+} doped potassium gadolinium tungstate—KGd(WO{sub 4}){sub 2}:Nd{sup 3+}—crystal powder is demonstrated. The powder was excited at 813 nm in resonance with the Nd{sup 3+} transition {sup 4}I{sub 9/2}→{sup 4}F{sub 5/2}. RL emission at 1067 nm due to the {sup 4}F{sub 3/2}→{sup 4}I{sub 11/2} transition was observed and characterized. An intensity threshold dependent on the laser spot area and bandwidth narrowing from ≈2.20 nm to ≈0.40 nm were observed and measured. For a beam spot area of 0.4 mm{sup 2}, a RL threshold of 6.5 mJ/mm{sup 2} (90 MW/cm{sup 2}) was determined. For excitation intensity smaller than the RL threshold, only spontaneous emission from level {sup 4}F{sub 3/2} with decay time in the tens microsecond range was observed, but for excitation above the RL threshold, significant shortening of excited level lifetime, characteristic of a stimulated process was found. The overall characteristics measured show that KGd(WO{sub 4}){sub 2}:Nd{sup 3+} is an efficient material for operation of solid state RLs in the near-infrared.

Discrete multi-wavelength operation of a diode-pumped Nd:GdVO4 laser at four different wavelengths was demonstrated using a single birefringent filter plate. The laser achieved maximum output powers of 5.92 W, 5.66 W, 5.56 W and 3.98 W at 1063.2 nm, 1070.8 nm, 1082.5 nm and 1086.2 nm wavelengths, respectively. To the best of our knowledge, apart from achieving the maximum output powers at ~1071 nm and ~1086 nm and best efficiencies at ~1071 nm, ~1083 nm and ~1086 nm wavelengths for a Nd:GdVO4 laser, this is also the largest number of wavelengths from the 4F3/2  →  4I11/2 transition that was ever obtained in a controlled manner from a single laser setup based on any of the Nd-doped laser crystals.

Novel cancer cellular therapy approaches involving long-term ex vivo IL-2 stimulated highly cytotoxic natural killer (NK) cells are emerging. However, adhesion properties of such NK cells are not very well understood. Herein, we describe the novel observation of permanently activated alphaLbeta2 integrin leukocyte function-associated antigen (LFA)-1 adhesion receptor in long-term IL-2 activated NK cells and the permanent NK cell lines KHYG-1 and NK-92. We show that such cytokine activated NK effectors constitutively adhered to the LFA-1-ligand ICAM-1, whereas binding to the lower affinity ligand ICAM-3 required additional exogenous activating conditions. The results demonstrate an extended conformation and an intermediate affinity state for the LFA-1 population expressed by the NK cells. Interestingly, adhesion to ICAM-1 or K562 induced pronounced cell spreading in KHYG-1, but not in NK-92, and partially in long-term IL-2 stimulated primary NK cells. It is conceivable that such differential adhesion characteristics may impact motility potential of such NK effectors with relevance to clinical tumor targeting. KHYG-1 could be a useful model in planning future targeted therapeutic approaches involving NK effectors with augmented functions.

2012-01-01

Intra-cavity frequency doubling of continuous-wave (CW) laser emission on the quasi-three level ( 4 F 3/2 → 4 I 9/2 ) laser transition of Nd 3+ in Nd:GGG is reported by using a three-mirror folded resonator. The thermal lens experienced by the optically-pumped Nd:GGG laser crystal is measured as a function of the absorbed pump power and compared to that found, in the same conditions, in the case of Nd:YAG. Results are interpreted by using a simple model accounting for the absorbed pump power and the thermo-mechanical properties of each laser crystal. Diode-pumped blue laser operation is achieved, for the first time, at 467.0 and 468.5 nm with output powers of 230 and 450 mW, respectively. Simultaneous laser operation resulting both from frequency-doubling and frequency summing at the three 467.1, 467.7, and 468.1 nm laser wavelengths is also obtained with a total output power of 60 mW

Improvement of the magnetic moment of NiZn ferrites induced by substitution of Nd3+ ions for Fe3+ ions

Science.gov (United States)

Wu, Xuehang; Chen, Wen; Wu, Wenwei; Wu, Juan; Wang, Qing

2018-05-01

Four types of Ni-Zn based ferrites materials having the general formula Ni0.5Zn0.5NdxFe2-xO4 (0.0 ≤ x ≤ 0.12) have been successfully synthesized by calcining oxalates in air and the influence of Nd content on the structure and magnetic properties of Ni0.5Zn0.5NdxFe2-xO4 is studied. X-ray diffraction examination confirms that a high-crystallized Ni0.5Zn0.5NdxFe2-xO4 with cubic spinel structure is obtained when the precursor is calcined at 1000 °C in air for 2 h. The substitutions of Nd3+ ions for partial Fe3+ ions do not change the spinel crystalline structure of MFe2O4. The incorporation of Nd3+ ions in place of Fe3+ ions in Ni-Zn ferrites increases the average crystallite size. Specific saturation magnetization decreases with increase in Nd content. This is because Nd3+ ions with smaller magnetic moment preferentially fill the octahedral sites. In addition, antiferromagnetic FeNdO3 increases with increase in Nd content. In this study, Ni0.5Zn0.5Nd0.08Fe1.92O4, calcined at 1000 °C, exhibits the highest magnetic moment (4.2954 μB) and the lowest coercivity (28.82 Oe).

NdFeB films with Nd compositions varied from 13.34 to 24.30 at% were deposited by DC gradient sputtering using targets Nd 12.5 Fe 71.5 B 16 and Nd. The hard magnetic properties, grain growth direction and magnetic domain structures were dramatically influenced by Nd composition. The samples with intermediate Nd concentrations exhibited optimal magnetic properties and microstructures, such as large squareness ratio over 0.9, large energy product up to 174 kJ/m 3 , and vertical domain structure. However, the samples with higher and lower Nd compositions showed almost isotropic loops.

Full Text Available Characterization of two rapid-quenched Nd-Fe-B alloys with nonstoichiometric Nd content in the optimized magnetic state was carried out using the X-ray diffractometry (XRD, 57Fe Mössbauer spectroscopic phase analysis (MS, electron microscopy (TEM, high resolution TEM (HREM and Superconducting Quantum Interference Device (SQUID magnetometer. The experimental results demonstrate the fundamental difference in the structure and magnetic properties of the two investigated alloys in the optimized magnetic state. The Nd-Fe-B alloy with the reduced Nd content (Nd4.5Fe77B18.5 was found to have the nanocomposite structure of Fe3B/Nd2Fe14B and partly α-Fe/Nd2Fe14B, with mean grain size below 30 nm. On the other side, the overstoichiometric Nd14Fe79B7 alloy has almost a monophase structure with the dominant content of the hard magnetic phase Nd2Fe14B (up to 95 wt. % and a mean crystallite size about 60 nm, as determined by XRD and TEM analysis. The results of magnetic measurements on SQUID magnetometer also suggest the nanocomposite structure of the Nd-low alloy and nanocrystalline decoupled structure of the Nd-rich alloy after the optimal heat treatment.

Spectroscopic and radiative properties study of Nd3+ doped cadmium-phosphate glasses

International Nuclear Information System (INIS)

Mahmoud, K.H.

2010-01-01

A spectroscopic investigation is performed on Nd 3+ doped cadmium-phosphate glasses. The Judd-Ofelt analysis is applied to the glass system in order to evaluate their potential as both glass laser and amplifier materials. The phenomenological Judd-Ofelt parameters Ω (2) , Ω (4) , and Ω (6) are determined, their values are 4.80x10 -20 , 6.18x10 -20 , and 7.14x10 -20 cm -2 , respectively. The quality factor for glass system is 0.86. Predicted radiative decay rates and branching ratios of transitions from Nd 3+4 F 3/2 state to the 4 I J manifolds are determined and analyzed. The calculated lifetime of the 4 F 3/2 metastable state of Nd 3+ is 31 μs. The results showed that 4 F 3/2 to 4 I 11/2 transition, with fluorescence at 1056 nm, has the most potential for laser application. Photoluminescence up-conversion under excitation at 488 nm laser light exhibits three emission bands of Nd 3+ ions at 541 (green), 601 (orange), and 677 nm (red). These emission bands are assigned to 4 G 7/2 → 4 I 9/2 , 4 G 7/2 → 4 I 11/2 , and 4 G 7/2 → 4 I 13/2 transitions, respectively. Analysis of luminescence spectra enhances the use of glass system in optical displays, lasers, and optical memory devices.

Full text: When 20 mg/L,100 mg/L Nd(NO 3 ) 3 were applied at rape seedling stage, the uptake of N, P, K by rape was significantly increased. The main characters of economic importance in rape were also improved, such as dry weight, root length, pod number and 1000-seed weight. Yields of rape seeds were 110.77% and 122.50% of control, respectively. The contents of Nd, Ca in plant and soluble Nd in the soil were also analysed. It was found that Nd could be absorbed from leaves and transported to the top as well as the roots. The uptake of Nd from soil was inhibited by Nd absorption from leaves. Nd might replace Ca partly

Rare earth element concentrations and Nd isotopes in the Southeast Pacific Ocean

Science.gov (United States)

Jeandel, C.; Delattre, H.; Grenier, M.; Pradoux, C.; Lacan, F.

2013-02-01

vertical profiles of rare earth element concentrations and Nd isotopic compositions have been measured in the remote southeast Pacific Ocean. The three stations represent contrasting environments: the oligotrophic center of the gyre (station GYR), the "transition zone" east of the South Tropical Front (station EGY), and the Peru-Chile upwelling marked by a pronounced oxygen minimum (station UPX). Rare earth concentrations display nutrient like vertical profiles except at UPX where surface waters are enriched. At this station Nd isotopic compositions are clearly more radiogenic than in the open ocean, suggesting that boundary exchange process is releasing lithogenic rare earth element from the volcanic Andes. Unexpected radiogenic values (ɛNd reaching -3.7) are also observed at 2000 m at station GYR in the Upper Circumpolar Deep Water that commonly have ɛNd values around -6. Exchange processes related to hydrothermal activity are suspected to produce this increase in ɛNd in the vicinity of the East Pacific Rise. These results provide some guidance for higher resolution studies planned in this region by the international GEOTRACES program.

"Just as the Structural Formula Does": Names, Diagrams, and the Structure of Organic Chemistry at the 1892 Geneva Nomenclature Congress.

Science.gov (United States)

Hepler-Smith, Evan

2015-02-01

At the Geneva Nomenclature Congress of 1892, some of the foremost organic chemists of the late nineteenth century crafted a novel relationship between chemical substances, chemical diagrams, and chemical names that has shaped practices of chemical representation ever since. During the 1880s, the French chemist Charles Friedel organised the nomenclature reform effort that culminated in the Geneva Congress; in the disorderly nomenclature of German synthetic chemistry, Friedel saw an opportunity to advance French national interests and his own pedagogical goals. Friedel and a group of close colleagues reconceived nomenclature as a unified field, in which all chemical names ought to relate clearly to one another and to the structure of the compounds they represented. The German chemist Adolf von Baeyer went a step farther, arguing for names that precisely and uniquely corresponded to the structural formula of each compound, tailored for use in chemical dictionaries and handbooks. Baeyer's vision prevailed at the Geneva Congress, which consequently codified rules for rigorously mapping structural formulas into names, resulting in names that faithfully represented the features of these diagrams but not always the chemical behaviour of the compounds themselves. This approach ultimately limited both the number of chemical compounds that the Geneva rules were able to encompass and the breadth of their application. However, the relationship between diagram and name established at the Geneva Congress became the foundation not only of subsequent systems of chemical nomenclature but of methods of organising information that have supported the modern chemical sciences.

Taking Congress Home: Effects of NC 4-H Congress on Youth Behaviors and Intentions

Directory of Open Access Journals (Sweden)

Benjamin Silliman

2008-03-01

Full Text Available This evaluation report describes the outcomes and quality of the 2006 North Carolina 4-H Congress, an annual five-day teen conference focused on citizenship, leadership, and service. A majority of returning youth cited Congress experiences as significant in their continued learning and practice in citizenship, leadership, and service learning. Likewise, most youth participants in the 2006 conference indicated that they planned to participate in more citizenship, community leadership, and service activities in their home communities. A Youth Program Climate survey revealed that youth viewed NC 4-H Congress as a setting where service was important, where they learned to accept differences, teamwork was emphasized, and where they were able to make a difference in the lives of others. Three implications of the evaluation report are discussed: 1 value of a youth leadership conference for educating and inspiring youth in citizenship, leadership, and service; 2 evaluation methodology, including engaging youth leaders in design and use of conference data; and 3 marketing and accountability opportunities resulting from program evaluations.

A diode-pumped laser amplifier model is derived from first principles and applied to a Nd:YAG amplifier operating on the {sup 4}F{sub 3/2} to {sup 4}I{sub 9/2} transition at 0.946 {mu}m. The effects of amplified spontaneous emission are included in the model and the addition of this effect is shown to produce better agreement with the data. The amplifier model includes effects of the transverse and longitudinal variation of the pump beam, transverse and longitudinal variation of the probe beam, and multiple passes of the probe beam. Experimental results obtained with a quasi four-level Nd:YAG amplifier operating at 0.946 {mu}m are used to validate the model. The amplifier was evaluated as a function of the pump energy, the probe energy, the probe beam radius, the pulse repetition frequency and the temperature. For all of the experimental conditions, the experimental results and the model agree.

Phase equilibrium is established in a Nd-Mn-O system at 1100 C by changing the oxygen partial pressure from 0 to 12.00 in -log(Po(sub 2)/atm); a phase diagram at 1100 C is presented for a Nd(sub 2)O(sub 3)-MnO-MnO(sub 2) system. Under the experimental conditions, Nd(sub 2)O(sub 3), MnO, Mn(sub 3)O(sub 4), and NdMnO(sub 3) phases are present at 1100 C, but Nd(sub 2)MnO(sub 4), Mn(sub 2)O(sub 3), and MnO(sub 2) are not stable in the system. Wide ranges of nonstoichiometry were found in the NdMnO(sub 3) phase, which coexisted with Nd(sub 2)O(sub 3). X ranges from -0.006 at log Po(sub 2)=-10.85 to 0.104 at log Po(sub 2)=0 in the form of NdMnO(sub 3+X). The nonstoichiometry is represented by the equation No/N(sub NdMnO(sub 3))=4.34x10(sup -5)(log Po(sub 2))(sup 3)+1.99x10(sup -3)(log Po(sub 2))(sup 2)+2.65x10(sup -2)(log Po(sub 2))+0.104; the activities of the components in the solid solution are also calculated with this equation. NdMnO(sub 3) has a composition range to the Nd(sub 2)O(sub 3)-rich or Nd(sub 2)O(sub 3)-poor side of LaMnO(sub 3). Lattice constants of NdMnO(sub 3) made in different oxygen partial pressures were determined

Rare earth (Er3+ and Nd3+) ions doped cadmium lithium boro tellurite (CLiBT) glasses were prepared by melt quenching method. The vis-NIR absorption spectra of these glasses have been analyzed systematically. Judd-Ofelt intensity parameters Ωλ (λ = 2, 4, 6) have been evaluated and used to compute the radiative properties of emission transitions of Er3+ and Nd3+: CLiBT glasses. From the NIR emission spectra of Er3+: CLiBT glasses a broad emission band centered at 1538 nm (4I13/2 → 4I15/2) is observed and from Nd3+: CLiBT glasses, three NIR emission bands at 898 nm (4F3/2 → 4I9/2), 1070 nm (4F3/2 → 4I11/2) and 1338 nm (4F3/2 → 4I13/2) are observed with an excitation wavelength λexci = 514.5 nm (Ar+ Laser). The FWHM and stimulated emission cross-section values are calculated for Er3+ and Nd3+: CLiBT glasses. FWHM × σeP values are also calculated for Er3+: CLiBT glasses.

Lee, Y. I.; Huang, G. Y.; Shih, C. W.; Chang, W. C.; Chang, H. W.; You, J. S.

2017-10-01

Magnetic properties of the anisotropic NdFeB magnets prepared by hot pressing followed by die-upsetting NdFeB MQU-F powders doped with low-melting RCu alloy powders were explored, where RCu stands for Nd70Cu30, Dy70Cu30 and (Nd0.5Dy0.5)70Cu30, respectively. In addition, the post-annealing at 600 °C was employed to modify the microstructures and the magnetic properties of the hot deformed magnets. It is found that doping RCu alloy powders is effective in enhancing the coercivity of the hot deformed NdFeB magnets from 15.1 kOe to 16.3-19.5 kOe. For Nd70Cu30-doped magnets, the increment of coercivity is only 1.2 kOe. Meanwhile, Dy70Cu30-doped and (Nd0.5Dy0.5)70Cu30-doped magnets show an almost identical enhancement of coercivity of about 4.4 kOe. Importantly, the latter magnet shows a beneficial effect of reducing the usage of Dy from 1.6 wt% to 0.8 wt%. TEM analysis shows that nonmagnetic Nd, Dy and Cu appear at grain boundary and isolate the magnetic grains, leading to an enhancement of coercivity. Doping lower melting point Dy-lean (Nd0.5Dy0.5)70Cu30 powders into commercial MQU-F powders for making high coercivity hot deformed NdFeB magnets might be a potential and economic way for mass production.

In this study the tourism marketing mix, programming, packaging, partnership, people, product, price, promotion, place, are adapted for congress tourism and a model which illustrates how to use the creative tourism experiences and activities within the marketing mix is proposed.

From Terrorism to Politics, the World Armenian Congresses (1979-1985

Full Text Available Armenians who had used terrorism in order to gain their independence since the second half of the 19th century continued this policy during the World War I and also after the war. When they began terrorism activities again in 1970s, their aim was to draw the attention of world public to Armenian Issue. Reaching their aim, Armenians also sought to move the issue into the political arena. To this end, in 1979, 1983 and 1985, the World Armenian Congresses were organized by the Swiss James Viktor Karnusyan. The overall objective of the Congresses was to combine the Armenians scattered in different parts of the world in a political platform and by doing so make world states, at first Turkey, accept the Armenian Genocide. However, two main problems were about the congresses. The first one was that these congresses were in the shadow of the terrorism, and the other one was that the traditional Armenian Parties did not support these congresses. Despite all of them, the decisions taken at the congresses, the National Council of Armenian that was created and Armenian Constitution which was declared had historical nature. In addition, it is evident that these congresses also had a role in transporting the Armenian issue into the Political platform.

Phase equilibrium of the system Ag-Fe-Nd, and Nd extraction from magnet scraps using molten silver

Takeda, O.; Okabe, T.H.; Umetsu, Y.

2004-01-01

To develop a new recycling process, we examined the direct extraction of neodymium (Nd) metal from Nd-Fe-B magnet scraps using molten silver (Ag) as an extraction medium. Prior to the extraction experiment, the phase equilibrium of the system Ag-Fe-Nd was investigated to estimate the theoretical extraction limit. It was observed that the Fe/Nd 2 Fe 17 mixture equilibrates with the molten Ag-Nd alloy containing 50-52 mol% Nd (57-59 mass% Nd) at 1363 K. The experimental results were in good agreement with the thermodynamic calculation based on literature values. By reacting Nd-Fe-B magnet scraps with molten silver at 1273 K, more than 90% of the neodymium in the scrap was extracted, and an Ag-Nd alloy containing 40-50 mass% Nd was obtained. The neodymium in the Ag-Nd alloy was separated from silver as Nd 2 O 3 by oxidizing the obtained alloy in air. Although the wettability of Nd 2 O 3 with molten silver caused some difficulties in the separation of neodymium from silver, molten silver is shown to be an effective medium for neodymium extraction from magnet scrap

Local distortions about Nd in NdO{sub s4}Sb{sub 12}

2013-02-15

We present an extended X-ray absorption fine structure (EXAFS) study of the NdOs{sub 4}Sb{sub 12} system at the Nd and Os L{sub III} edges. Nd is expected to be a ''rattler'' atom in this skutterudite crystal and we obtain a low Einstein temperature (61 K) as expected. However, although ultrasonic measurements have suggested a large off-center displacement of Nd, the EXAFS data are inconsistent with such a model. An analysis of the first two Os-Sb peaks in the Os L{sub III} data also shows no evidence for unusual disorder. In contrast the Nd-Os peak in the Nd L{sub III} data and the Os-Os peak in the Os L{sub III} data both show significant disorder at 4 K, with the largest disorder found for the Nd-Os pair. This suggests that a distortion of the structure that involves mainly the Os atoms is present; it is likely that this distortion - which may also be dynamic - also causes the anomalies in the ultrasonic data (copyright 2012 WILEY-VCH Verlag GmbH and Co.

X-ray diffraction and magnetic studies of neodymium deficient Nd 0.9-x Ca x MnO y (0= 0.9 MnO y samples have been prepared in the 2.85= g -orbitals of manganese ions. Composition with y=2.85 is antiferromagnet with T N =85K, whereas for more oxidized Nd 0.9 MnO y samples a coexistence of antiferromagnetic and ferromagnetic phases is suggested. Low-temperature magnetic phase transition which is accompanied by a negative magnetization appearance has been found in the Nd 0.9 MnO 2.90 compound. Magnetic behavior of Nd 0.9-x Ca x MnO y (0.1= 1-x Ca x MnO 3 series. Properties of the Nd 0.9-x Ca x MnO y (0=< x=<0.4) solid solutions are in agreement with a hypothesis according to which a part of Nd ions can be substituted by Mn ions

Concentration quenching in Nd-doped glasses

Stokowski, S.E.; Cook, L.; Mueller, H.; Weber, M.J.

Fluorescence from trivalent Nd in solids is unfortunately quenched by interactions between Nd ions. Thus, laser materials with high Nd concentrations have reduced efficiencies because of this self-quenching, also known as concentration quenching. Nd self-quenching in different crystals and glasses varies considerably. We are therefore investigating this effect in a large number of materials in an effort to: (1) find those materials with long Nd fluorescent lifetimes at high Nd concentrations; and (2) elucidate the basic mechanisms of quenching and how the material structure controls its magnitude. We have concentrated on Nd-doped glasses because they provide a rich variety of structures, albeit complicated by Nd site inhomogeneities, and are easily and quickly made

Empirical evidence has indicated that only a subsample of studies conducted reach full-text publication and this phenomenon has become known as publication bias. A form of publication bias is the selectively delayed full publication of conference abstracts. The objective of this article was to examine the publication status of oral abstracts and poster-presentation abstracts, included in the scientific program of the 82nd and 83rd European Orthodontic Society (EOS) congresses, held in 2006 and 2007, and to identify factors associated with full-length publication. A systematic search of PubMed and Google Scholar databases was performed in April 2013 using author names and keywords from the abstract title to locate abstract and full-article publications. Information regarding mode of presentation, type of affiliation, geographical origin, statistical results, and publication details were collected and analyzed using univariable and multivariable logistic regression. Approximately 51 per cent of the EOS 2006 and 55 per cent of the EOS 2007 abstracts appeared in print more than 5 years post congress. A mean period of 1.32 years elapsed between conference and publication date. Mode of presentation (oral or poster), use of statistical analysis, and research subject area were significant predictors for publication success. Inherent discrepancies of abstract reporting, mainly related to presentation of preliminary results and incomplete description of methods, may be considered in analogous studies. On average 52.2 per cent of the abstracts presented at the two EOS conferences reached full publication. Abstracts presented orally, including statistical analysis, were more likely to get published. © The Author 2013. Published by Oxford University Press on behalf of the European Orthodontic Society.

Chronology of the 1st–2nd Century Graves from the Tarasovo Burial Ground

Directory of Open Access Journals (Sweden)

2016-03-01

Full Text Available The article focuses on the chronology of graves dating back to the early (1st – 2nd centuries AD – Nyrgynda stage of the 1st – 5th century Tarasovo burial ground, a classical monument attributed to the Cheganda culture of the Pyany Bor cultural-historical community. Cultural stratigraphy is applied as a research method. Artifacts from the early stage were correlated for 37 male and 102 female complexes, separately. The analysis of grave goods from male burials showed the following three chronological groups, that can be distinguished at the Nyrgynda stage: 1st century (group 1, 2nd century (group 2 and 1st – 2nd centuries AD (group 3. The goods from female graves are more representative and various, so three more groups with shorter chronological lives can be singled out: the fi rst half of the 2nd century (group 2а, the second half of the 2nd century (group 2б and the 1st – fi rst half of the 2nd century (group 4. Certainly, the suggested chronology leaves room for any eventual corrections subject to new findings.

Applications of function theory of several complex variables to pde, 3. Integral equations and boundary value problems, 4. Partial differential equations. Most but not all of the authors have participated in the congress. Unfortunately some from Eastern Europe and Asia have not managed to come because of lack of financial support. Nevertheless their manuscripts of the proposed talks are included in this volume. The majority of the papers deal with complex methods. Among them boundary value problems in particular the Riemann-Hilbert, the Riemann (Hilbert) and related problems are treated. Boundary behaviour of vector-valued functions are studied too. The Riemann-Hilbert problem is solved for elliptic complex equations, for mixed complex equations, and for several complex variables. It is considered in a general topological setting for mapping...

This study provides the influence of microstructural change of the interface between Nd 2 Fe 14 B and Nd-O phases on coercivity of Nd-Fe-B thin films during annealing at low temperature (∼350 deg. C). All films were prepared by using ultra high vacuum (UHV) magnetron sputtering, and the Nd-Fe-B layer was oxidized under Ar gas atmosphere (O 2 content; ∼2 Vol.ppm). Then, the films were annealed at 250-350 deg. C under UHV condition. After oxidation, the coercivity of Nd-Fe-B film decreased to around 40% of the coercivity of as-deposited Nd-Fe-B film. The Nd-rich phase changed from α-Nd to amorphous Nd(-O), and the interface of Nd 2 Fe 14 B/Nd(-O) became rough. In the Nd-Fe-B films oxidized and subsequent annealed at 350 deg. C, the coercivity decreased to around 20%. In the films, poly crystalline hcp Nd 2 O 3 phase crystallized in Nd-rich phase, and there were some steps at the surface of Nd 2 Fe 14 B phase contacting with hcp Nd 2 O 3 phase. Regardless of crystal orientation of Nd 2 Fe 14 B, the microstructural changes of the interface described above were observed.

Lifetimes of low-lying states have been measured in 132 Nd and 134 Nd using the coincidence-plunger technique. The reaction 32 S+ 105 Pd was used at a bombarding energy of 152 MeV. The measurement has been performed at the NSF Daresbury using the ESSA 30 array. The differential decay-curve method (DDCM) was used to analyze the recoil-distance Doppler-shift (RDDS) data. The experimental B(E2) values in 132 Nd are well described by the predictions of the rotational model and the IBM in the O(6) limit. ((orig.))

The Salobo 3A polymetallic Cu (Au-Mo-Ag) deposit, located in the northern part of the Carajas Mineral Province, Para, consists of a metavolcano-sedimentary sequence represented by iron formation, amphibolite, schist and quartzite of the Igarape Salobo Group. This rock sequence rest uncomformably on the gneissic basement of the Xingu Complex. The copper mineralization hosted by iron formation consists of bornite-chalcocite and bornite-chalcopyrite disseminations associated with magnetite. The geochronological data determined through the application of the Rb-Sr, Sm-Nd and Pb-Pb methods, contribute to characterize the complex evolution of both the geological setting and the cupriferous mineralization of the Salobo deposit. The 3.11-2.92 Ga interval (T{sub DM}, Sm-Nd, whole rock) represents the age of the igneous protholith of the gneiss. The {epsilon}{sub Nd} values calculated for the time of the gneiss formation (2859 Ma) vary between +1.02 and -1.08, and indicate a short period between the mantle-crust differentiation epoch and the gneiss formation. Moreover, the {epsilon}{sub Nd} parameter suggest a mantle source with late crustal contamination. The application of the leaching technique allows a gradual extraction of Pb at each leaching step and it was applied to chalcocite and magnetite. The 2762 {+-} 180 Ma and 2776 {+-} 240 Ma ages determined on those minerals are interpreted to be close to the epoch of the formation of the copper mineralization with Uu and Th enrichment and of the iron formation deposition, respectively, in a conventional setting. The leaching technique was also applied to tourmaline from gneiss and quartzite, and the age near to 2400 Ma was attributed to its formation. The random variability of the Pb isotope compositions of the tourmaline together with its petrographic characteristics suggest the boron source is not associated with the metassedimentary rocks of the Igarape Salobo Group.

Research highlights: → The enthalpies of formation of the compounds Cu 6 Nd, Cu 5 Nd, Cu 2 Nd and αCuNd were calculated using DFT. → The thermodynamic constraints to eliminate the artificial phase relations were imposed during the thermodynamic optimization procedure. → The Cu-Nd system was optimized under the thermodynamic constraints. - Abstract: The thermodynamic constraints to eliminate artificial phase relations were introduced with the Cu-Nd system as an example. The enthalpies of formation of the compounds Cu 6 Nd, Cu 5 Nd, Cu 2 Nd and αCuNd are calculated using density functional theory. Taking into account all the experimental data and the first-principles calculated enthalpies of formation of these compounds, the thermodynamic optimization of the Cu-Nd system was performed under the proposed thermodynamic constraints. It is demonstrated that the thermodynamic constraints are critical to obtain a set of thermodynamic parameters for the Cu-Nd system, which can avoid the appearance of all the artificial phase relations.

Subduction Contributions in the Trans-Mexican Volcanic Belt: Implications from Lava Chemistry and Hf-Nd-Pb Isotopes

Despite thick continental crust, near primitive lavas erupt throughout the Trans-Mexican Volcanic Belt (TMVB). In order to distinguish and better constrain subduction contributions and effects of crustal contamination, we analyzed samples representing subducting sediments from DSDP Site 487, and Quaternary lavas from stratovolcanoes and cinder cones, including alkaline "high-Nb" lavas from the Sierra Chichinautzin Volcanic Field (SCVF) showing negligible subduction signature in its trace element chemistry and representing melts of the mantle wedge. Our primary observations and implications are: (1) The high-Nb SCVF `intraplate' lavas define a linear trend along the "Nd-Hf mantle-crust array", defining the composition of the mantle wedge. (2) Popocatepetl and Nevado de Toluca stratovolcanoes show the highest Nd and Hf isotope ratios, higher than the `intraplate' lavas, indicating their sources are more "depleted mantle-like" than the regional mantle wedge. (3) The Popo and Toluca chemical and isotopic trends sharply contrast with Pico de Orizaba, which shows classic indications of crustal contamination (e.g. high 207Pb/204Pb, low Nd-Hf isotope ratios), consistent with contamination by local Precambrian crust. (4) Higher Nd-Hf isotopes in Popo and Toluca lavas also correlate with lower Pb isotope ratios, and lower Lu/Hf and Zr/Hf. Together, these data indicate contributions from subducted Pacific oceanic crust and hydrothermal sediment. (5) Popo and Toluca are also enriched in Th/LREE compared with `intraplate' lavas, reflecting subducted sediment contributions. (6) Nd-Hf isotope ratios of hydrothermal sediment from DSDP Site 487 lie on the "seawater array", with high Hf isotope ratios compared to the "mantle-crust array". Popo and Toluca Nd-Hf isotopes display a shallower slope than the "intraplate lava Nd-Hf array", reflecting contributions from hydrothermal sediment. Popocatepetl and Toluca lavas therefore avoid substantial crustal contamination of mantle wedge

minority sites in these crystals as due to non-stoichiometric or inversion charge defects of the type RE 3+ -> 2+ or RE 3+ in Ca 2+ sites were proposed and their effects in emission investigated. Extended energy level schemes for Yb 3+ and Nd 3+ prevailing (in RE 3+ sites) and minority centers in GdCOB and YCOB were determined. A theoretical parametric crystal field calculation was performed for Nd 3+ by varying free ion and crystal field parameters. A characteristic of the crystal field parameters is the large value of the second order parameters that leads to a strong splitting of metastable 4 F 3/2 Nd 3+ level (∼190 cm -1 ) that leads to a parasitic effect for Nd 3+ in GdCOB, i. e. the shift of the laser emission from 1.06 mm to 1.09 mm at high pumping. The spectroscopic bases for the improvement of the laser emission parameters in fundamental and self-doubling regime of Nd 3+ : GdCOB and the reduction of heat generation were investigated. The analysis of spectral data shows that the laser emission parameters of Nd 3+ in GdCOB at 1.06 mm can be improved by direct pumping in the emitting level in the band 4 I 9/2 (Z 2 )→ 4 F 3/2 (R 1 ) at 887 nm, instead of using the usual diode pumping in the line 4 I 9/2 (Z 1 )→ 4 F 5/2 (S 1 ) at 811 nm. Experimental investigations confirmed this idea and for fundamental emission at 1.06 mm the slope efficiency increased from ∼ 0.46 to ∼ 0.61 while the threshold decreased from ∼ 115 mW to ∼ 75 mW. The parasitic change of emission wavelength at high powers did not show. These improvements are amplified in self-doubling emission. The emission characteristics under direct pump 887 nm as compared to the conventional pump 811 nm are evidently improved. Thus at 600 mW absorbed power the emitted power in green was 2.16 larger than with conventional pumping. (authors)

The subsolidus phase relations of the Bi 2 O 3 -Nd 2 O 3 -CuO ternary system and its binary systems along with crystallographic parameters of the compounds were investigated by X-ray powder diffraction and differential thermal analysis. The room temperature section of the phase diagram of the Bi 2 O 3 -Nd 2 O 3 -CuO system can be divided into two diphase regions and six triphase regions. No ternary compound was found. There exist two solid solutions (α, β) and a compound Bi 0.55 Nd 0.45 O 1.5 in the (Bi 2 O 2 ) 1-x (Nd 2 O 3 ) x system. Both solid solution α (0.05≤x≤0.30) and β (0.53≤x≤0.73) belong to the rhombohedral system (R3m). The lattice parameters represented by a hexagonal cell are a=3.9832(4), c=27.536(5) A for Bi 0.8 Nd 0.2 O 1.5 (α phase) and a=3.8826(3), c=9.727(1) A for Bi 0.4 Nd 0.8 O 1.5 (β phase). The Bi 0.55 Nd 0.45 O 1.5 compound crystallizes in a face-centered cubic (f.c.c.) lattice with a=5.5480(2) A. (orig.)

Near-infrared (NIR) emitting phosphors of different alkaline based sodium-phosphate (MNa[PO4], where M = Mg, Ca, Sr and Ba were prepared by a conventional solution combustion method with fixed doping concentration of Nd3+ (1.0 mol%). The phosphors were characterized by powder X-ray diffraction, field emission scanning electron microscope, Fourier transform infrared spectroscopy, UV-vis spectroscopy and fluorescent spectrophotometry. The optical properties including reflectance, excitation and emission were investigated. The excitation spectra of the phosphors were characterized by a broadband extending from 450 to 900 nm. Upon excitation with a wavelength of 580 nm, the phosphor emits intensely infrared region at 872 nm, 1060 nm and 1325 nm which correspond to the 4F3/2 → 4I9/2, 4F3/2 → 4I11/2 and 4F3/2 → 4I13/2 transitions of Nd3+ ions and were found to vary for the different hosts. The strongest emission wavelength reaches 1060 nm. The most intense emission of Nd3+ was observed from Ca2+ incorporated host. The down conversion emissions of the material fall in the NIR region suggesting that the prepared phosphors have potential application in the development of photonic devices emitting in the NIR.

Evaluation of the effects of alteration and leaching on Sm Nd and Lu Hf systematics in submarine mafic rocks

Science.gov (United States)

Thompson, Patricia M. E.; Kempton, Pamela D.; Kerr, Andrew C.

2008-08-01

Nd and Hf isotope systematics of oceanic basaltic rocks are often assumed to be largely immune to the effects of hydrothermal alteration. We have tested this assumption by comparing Nd and Hf isotope data for acid-leached Cretaceous oceanic basalts from Gorgona and DSDP Leg 15 with unleached data on the same rocks. Hf isotope values and Lu/Hf ratios are relatively unaffected by leaching, but 143Nd/ 144Nd values of leached samples are significantly higher than those of unleached fractions of the same sample in most cases. Furthermore, the Sm/Nd ratios of the majority of leached samples are 10-40% greater than those of unleached samples. X-ray diffraction studies indicate that selective removal of secondary minerals, such as smectite, during the acid leaching process is responsible for the fractionation of Sm/Nd ratios. These results have implications for interpretation of the Hf-Nd isotope systematics of ancient submarine rocks (older than ~ 50 Ma), as (1) the age-corrected 143Nd/ 144Nd ratio may not be representative of the primary magmatic signature and (2) the uncertainty of the age-corrected ɛNd value may exceed the assumed analytical precision.

Nd loaded liquid scintillator to search for 150Nd neutrinoless double beta decay

2008-01-01

The 150 Nd is considered one of the most attractive candidate for searching neutrinoless double beta (0νββ-) decay, thanks to its high Q-value (3.367 MeV), that makes the external background issue less significative respect to other isotopes, and favorable computed matrix elements. The isotopic abundance of this isotope in natural neodimium is only 5.6% and up to now, it has been investigated only in low mass experiments. The next step is to increase the sensitivity of the experiments using larger mass of neodymium (10 ton-1 kton). This could be possible with a Nd loaded liquid scintillator (LS). At the Gran Sasso National Laboratory (LNGS), a joint INFN (Istituto Nazionale di Fisica Nucleare) and INR (Institute for Nuclear Research of Moscow) working group has been carrying out since 2001 an R and D activity aiming to develop organic liquid scintillators (LS) doped with metals. The achieved know-how and the satisfactory results obtained both with In and Gd allowed to face the development and production of Nd doped LS. The development of metal doped LS is challenging because the metal has to be embedded in a proper organic system that makes it soluble in an organic solvent minimizing the impact of the metal-organic compound on the optical and scintillation properties of the LS. A further challenge in the case of Nd is the presence of absorption bands of this element in the optical region with a transparent region around 400 nm, which is about at the maximum of the scintillator emission spectrum. A 2.5 1 Nd loaded LS has been produced diluting an originally developed Nd-Carboxylic (Nd-CBX) salt in pseudocumene (PC), the solvent of the Borexino liquid scintillator. The measured light yield, at [Nd] = 6.5 g/1 and [PPO] = 1.5 g/1, is ∼ 75% of pure PC at the same fluor concentration (∼ 10000 ph/MeV). The Nd doped LS has been tested in a 2 1 quartz cell (wrapped by VM2000 reflector film) having dimensions 5x5x100 cm 3 . The light propagates in the cell by total

of Nd3+ions in YLiF4 and LuLiF4 crystals

Directory of Open Access Journals (Sweden)

André Felipe Henriques Librantz

2006-01-01

Full Text Available Nd3+ ultraviolet (UV fluorescence induced by multiphotonic laser excitations was studied in doped Nd:YLiF4 (YLF and Nd:LuLiF4 (LLF crystals by using the time resolved spectroscopy technique. The UV luminescences are due to transitions between the 4f25d and the 4f3 electronic configurations of Nd3+ ions. The 4f25d configuration can be reached by direct pumping or by multiphotonic excitation, both processes give rise to the UV band emission with structure due to the strong phonon coupling expected for 5d orbital involvement in the transition. The multiphotonic excitation process is due to three photons (532 nanometers [nm] sequential absorptions by metastable levels of the 4f3 configuration split by crystalline local field. The sequential excitation of Nd by the laser excitation is attributed to the 4I9/2 + 532 nm t 4G7/2 ground state absorption followed by the 4G7/2 + 532 nm t 2F5/2 and 2F5/2 + 532 nm t 4f25d excited state absorptions. The UV emissions due to 4f25d configuration are parity allowed, having lifetime of 35 nanoseconds (ns in contrast to UV emissions from 4f3 configuration which are induced by two absorption steps and are parity forbidden showing longer lifetime of 8 microseconds (ms and narrow lines. The polarization effects of the UV emissions were studied and their behaviors are dependent on the excited state configuration involving or not involving the 5d orbital. The allowed UV emission positions were affected by the host variation more than the ones originated from the 4f3 configuration as expected. The electronic energy of the 4f25d configuration shifts to lower energy for increasing the crystal field.

Shape transition in the Nd-isotopes

Sandor, Robert Karl Josef.

1991-01-01

In this thesis the results of an electron scattering experiment on 142 Nd, 146 Nd and 150 Nd, designed to study the influence of this shape transition an the low-lying excited states, have been presented and discussed. The spectra have been obtained at the high-resolution electron scattering facility of NIKHEF-K and cover a momentum transfer range from 0.5 up to 2.8 fm -1 . The experimental form factors and transition charge densities have been compared to two microscopic models, i.e. the Quasiparticle-Phonon Model for 142 Nd and 146 Nd and the Density-Dependent Hartree-Fock-Boguliubov model with a dynamical approach to calculate transition charge densities for 146 Nd and 150 Nd. The data obtained for the latter nuclei have also been compared to the macroscopic Rotation-Vibration Model. (author). 127 refs.; 49 figs.; 26 tabs

(Ce,Nd)-Fe-B sintered magnets were prepared by the addition of NdH{sub x} powders in Ce{sub 9}Nd{sub 4.5}Fe{sub 80}B{sub 6.5} powders. The coercivity is rather low in Ce{sub 9}Nd{sub 4.5}Fe{sub 80}B{sub 6.5} magnets, and Ce element prefers to distribute at the outer-layer of main phase (Ce,Nd){sub 2}Fe{sub 14}B. The investigation of scanning electron microscope shows that the addition of NdH{sub x} powders leads to the increase of Nd content at grain outer-layer of main phase owing to the element diffusion. Magnetization reversal undergoes the nucleation of reversed domain wall at grain outer-later, and the addition of NdH{sub x} powders leads to the increase in the nucleation field of reversed domain, giving rise to the significant improvement of coercivity. The larger amount addition of NdH{sub x} powders leads to the increase in the amount of intergranular phase, resulting in the decreases of the remanence, the squareness of demagnetization curve and the maximum energy product.

Nikolai Bogduk

2003-01-01

Full Text Available Conferences such as the International Congress on Whiplash Associated Disorders, held in Berne on March 8-10, 2001, serve several purposes. Socially, they provide an opportunity for delegates to see, hear and meet leading experts in the field, and those experts get to meet one another. Academically, such conferences offer delegates a synopsis of current information, provided by plenary lectures, and the opportunity to hear or contribute new information, in the form of free papers. A measure of the success of such a conference is the extent to which new information presented advances knowledge and understanding in the field. This essay provides an overview of the congress at hand. It compares what was known before the congress with what more was known as a result of the congress.

Structural and magnetic properties of NdFeB and NdFeB/Fe films with Mo addition

2011-07-06

The influence of the Mo addition on the microstructure and magnetic properties of Nd-Fe-B and Nd-Fe-B/Fe films was studied. The coercivity is a key parameter in the control of technical performances of Nd-Fe-B films. A small amount of about 1 at.% Mo can enhance the coercivity of Nd-Fe-B film by controlling the growth of soft and hard magnetic grains. A coercivity of 22.1 kOe, a remanence ratio, M{sub r}/M{sub s}, of 0.83 and a maximum energy product of 8 MGOe were obtained for Ta/[NdFeBMo(1at.%)(540nm)/Ta films annealed at 650{sup 0}C for 20 minutes due to Mo precipitates formed at the Nd{sub 2}Fe{sub 14}B phase boundaries which prevent the nucleation and expansion of the magnetic domains. Simultaneous use of Mo as addition and the stratification of Nd-Fe-B-Mo films using Fe as spacer layer are important tools for the improvement of the hard magnetic properties of Nd-Fe-B films. The Ta/[NdFeBMo(1at.%)(180nm)/Fe(1nm)]x3/Ta multilayer film annealed at 620{sup 0}C exhibits an increase in the coercivity from 12.1 kOe to 22.8 kOe, in the remanence ratio from 0.77 to 0.80, and in the maximum energy product from 4.5 to 7.1 MGOe in comparison with Ta/Nd-Fe-B/Ta film. As compared to Ta/Nd-Fe-B/Ta film, the Ta/[NdFeBMo(1at.%)(180nm)/Fe(1nm)]x3/Ta film presents a decrease in the crystallization temperature of about 30{sup 0}C.

Sm-Nd in marine carbonates and phosphates: implications for Nd isotopes in seawater and crustal ages

International Nuclear Information System (INIS)

Shaw, H.F.; Wasserburg, G.J.

1985-01-01

This study explores the possibility of establishing Nd isotopic variations in seawater over geologic time. Calcite, aragonite and apatite are examined as possible phases recording seawater values of epsilonsubNd. Modern, biogenic and inorganically precipitated calcite and aragonite from marine environments were found to have Nd concentrations of from 0.2 to 70 ppb, showing that primary marine CaCO 3 contains little REE and that Nd/Ca is not greatly enhanced relative to seawater during carbonate precipitation. Very young marine limestone and dolomite containing no continental detritus have approx. 200 ppb Nd. All the carbonates are LREE enriched. Modern and very young Atlantic and Pacific carbonates have epsilonsub(Nd) in the range of shallow Atlantic and Pacific seawater respectively, implying that they derive their REE from local seawater. The Nd in well preserved carbonate fossils is 4 ppb, much greater than in their modern counterparts but like the high values found for carbonates in other studies. Results are also reported for apatite. They suggest that sedimentary apatite can be used to determine epsilonsub(Nd)(T) in ancient seawater. The seawater values so inferred range between -1.7 and -8.9 over the last 700 my and lie in the range of modern seawater, showing no evidence for drastic changes. (U.K.)

2007-12-01

The International Geological Congress (IGC) has been arranged every four years since 1878. During the previous Congress in Florence, Italy, 2004, the Nordic countries were awarded the organisation of the 33rd IGC, which will be held in Oslo, Norway, August 6-14, 2008. We expect between 6000 and 9000 participants to the Congress, which also includes workshops, short-courses, and business meetings, as well as more than 50 pre -and post Congress excursions. The Congress is organised under the umbrella of IUGS and the patronage of UNESCO. The Congress will run with 40 parallel sessions and cover the whole width of the geosciences. About 500 symposia will run in 40 parallel sessions. There will be a major poster session, as well as a large exhibition (Geoexpo 2008), in which industry and other organisations will be able to exhibit their products and services. A number of international affiliations have announced their interest in organising annual business meetings during the Congress. In addition, a number of workshops and short-courses will be arranged. More than 50 excursions are planned for the two weeks before the Congress and one week after. These run in all the Nordic Countries, as well as in NW Russia, Ukraine, Greenland, Svalbard, and the Faeroes Islands. These excursions will give the participants a first-hand insight into Nordic Geosciences, as well as the Nordic natural and cultural heritage. Two major international events are important for the Congress. The "International Polar Year" (IPY) and the United Nations' "International Year of Planet Earth" (IYPE) are both running in the period 2007-2009. The Congress focuses on many of the main themes of IYPE, with major emphasis on "Geoscience and Society". Seven major themes will be treated in full-day plenary sessions of lectures given by invited lecturers. These plenary sessions will have a scientific part in the morning, a key-note lecture at lunch-time, and a societal part in the afternoon, followed by a

Synthesis, Cyclopolymerization and Cyclo-Copolymerization of 9-(2-Diallylaminoethyladenine and Its Hydrochloride Salt

Directory of Open Access Journals (Sweden)

Karyn Usher

2012-11-01

Full Text Available We report herein the synthesis and characterization of 9-(2-diallylaminoethyl adenine. We evaluated two different synthetic routes starting with adenine where the optimal route was achieved through coupling of 9-(2-chloroethyladenine with diallylamine. The cyclopolymerization and cyclo-copolymerization of 9-(2-diallylaminoethyladenine hydrochloride salt resulted in low molecular weight oligomers in low yields. In contrast, 9-(2-diallylaminoethyladenine failed to cyclopolymerize, however, it formed a copolymer with SO2 in relatively good yields. The molecular weights of the cyclopolymers were around 1,700–6,000 g/mol, as estimated by SEC. The cyclo-copolymer was stable up to 226 °C. To the best of our knowledge, this is the first example of a free-radical cyclo-copolymerization of a neutral alkyldiallylamine derivative with SO2. These polymers represent a novel class of carbocyclic polynucleotides.

The effects of pressure on the Nd{sup 3+}-doped MgO:LiNbO{sub 3} single crystal have been studied by luminescence spectroscopy at low temperature and high pressures from ambient conditions up to 33 GPa. Specifically, the pressure-induced evolution of the emission spectra, corresponding to the {sup 4}F{sub 3/2}→{sup 4}I{sub 9/2},{sup 4}I{sub 11/2} transitions, and the excitation spectra, corresponding to the {sup 4}I{sub 9/2}→{sup 4}F{sub 5/2}+{sup 2}H{sub 9/2}, and {sup 4}I{sub 9/2}→{sup 4}F{sub 7/2}+{sup 4}S{sub 3/2} transitions, show a gradual red-shift that follows a linear pressure dependence and a decrease in the intensity of the spectra with increasing pressure. The initial effect of increasing pressure on the MgO:LiNbO{sub 3} crystal is the modification of the relative amount of the several centers in the sample. At pressures around 20 GPa the characteristic multicenter Nd{sup 3+} structure eventually disappears indicating that all the centers have very similar environments near this pressure. At higher pressures, observed changes seem to have a different origin. The evolution of Nd{sup 3+} luminescence is studied in the frame of crystal-field theory in order to evaluate its capability of monitoring the pressure-induced structural changes. Crystal-field analysis, under approximated C{sub 3v} symmetry, shows a smooth increase of the overall crystal-field strength on the luminescent ion, which can be related to the volume reduction as pressure increases. Crystal-field parameters also show a general monotonic behavior with pressure that indicates a structural modification of the local structure that, maintaining the trigonal symmetry around the impurity ion, evolves towards a lower axial character. No evidences of a phase transition have been observed in the studied pressure range.

Congressing kinetochores progressively load Ska complexes to prevent force-dependent detachment.

Auckland, Philip; Clarke, Nicholas I; Royle, Stephen J; McAinsh, Andrew D

2017-06-05

Kinetochores mediate chromosome congression by either sliding along the lattice of spindle microtubules or forming end-on attachments to their depolymerizing plus-ends. By following the fates of individual kinetochores as they congress in live cells, we reveal that the Ska complex is required for a distinct substep of the depolymerization-coupled pulling mechanism. Ska depletion increases the frequency of naturally occurring, force-dependent P kinetochore detachment events, while being dispensable for the initial biorientation and movement of chromosomes. In unperturbed cells, these release events are followed by reattachment and successful congression, whereas in Ska-depleted cells, detached kinetochores remain in a futile reattachment/detachment cycle that prevents congression. We further find that Ska is progressively loaded onto bioriented kinetochore pairs as they congress. We thus propose a model in which kinetochores mature through Ska complex recruitment and that this is required for improved load-bearing capacity and silencing of the spindle assembly checkpoint. © 2017 Auckland et al.

Mesozoic-Cenozoic magmatic activities were intensive in Qinghai-Tibetan plateau. Nd-Sr isotopic compositions of representative granitic plutons in western Qinghai-Tibetan plateau are reported in this paper. Combining with past isotopic data, which has reported in eastern Qinghai-Tibetan plateau, Sr-Nd isotopic compositions and material source and genesis of Mesozoic and Cenozoic granites in Qinghai-Tibetan plateau have been studied. The research result indicates there are three types of granite existing in Qinghai-Tibetan plateau, the granites of Late stage of Yanshan Period which distributing on north and south boundary of Gandes block (namely in north and south granitic belts of Dangdes) and cause of oceanic crust subduction, have ( 87 Sr/ 86 Sr)i of 0.7041-0.7064, ε (Nd) t of +2.5 - +5.7 and TDM age of 312-562 Ma, positive ε Nd, low ( 87 Sr/ 86 Sr)i ratio and young Nd model ages suggest relatively high contents of mantle-derived components in their sources, and this type granite might melt from subduction oceanic crust. The granites occurred intra-Gangdes block which were caused by collision of continent and post-collision, have ( 87 Sr/ 86 Sr)i of 0.706-0.719, ε (Nd) t of -5.3 - -8.3 and TDM age of 1323-1496 Ma, negative ε Nd, relative high ( 87 Sr/ 86 Sr)i ratio with an mid-Proterozoic Nd model ages, suggest granite has the mixing genesis of mantle-derived components and old crustal components in their sources. With relatively small variation range in ε (Nd) t and TDM age, it might imply granitic isotopic source in Gandes block to keep relative homogenization in long period. The granites in Himalayan block which there is not oceanic material to join in melting and to cause of intra-continental subduction, has most ( 87 Sr/ 86 Sr)i ratio more than 0.720, ε (Nd) t of -10.3 - -16.3 and TDM age of 1792-2206 Ma, high ( 87 Sr/ 86 Sr)i ratio, low negative ε (Nd)t with old Nd isotopic model ages and consistent with the Sr, Nd isotopic compositions of basement

2013-01-01

Lanthanite-(Nd), ideally Nd2(CO3)3·8H2O [dineodymium(III) tricarbonate octa­hydrate], is a member of the lanthanite mineral group characterized by the general formula REE 2(CO3)3·8H2O, where REE is a 10-coordinated rare earth element. Based on single-crystal X-ray diffraction of a natural sample from Mitsukoshi, Hizen-cho, Karatsu City, Saga Prefecture, Japan, this study presents the first structure determination of lanthanite-(Nd). Its structure is very similar to that of other members of the lanthanite group. It is composed of infinite sheets made up of corner- and edge-sharing of two NdO10-polyhedra (both with site symmetry ..2) and two carbonate triangles (site symmetries ..2 and 1) parallel to the ab plane, and stacked perpendicular to c. These layers are linked to one another only through hydrogen bonding involving the water mol­ecules. PMID:23476479

A new laser medium Nd3+:GdTaO4 single crystal with high optical quality was grown successfully by the Czochralski method, and its high-efficiency laser operation at 1,066 nm was demonstrated for the first time. The absorption cross section of the crystal at 808 nm is 5.098 × 10-20 cm2, and the full width at half maximum of this absorption band is about 6 nm. Spectral properties are investigated by Judd-Ofelt theory. The stimulated emission cross section at 1,066 nm is 3.9 × 10-19 cm2, and the fluorescence lifetime of 4F3/2 level is 178.4 μs. A diode end-pumped Nd:GdTaO4 laser at 1,066 nm with the maximum output power of 2.5 W is achieved in the continuous-wave mode. The optical-to-optical conversion efficiency and slope efficiency are 34.6 and 36 %, respectively. In addition, the fluorescence branching ratio of 4F3/2 → 4I9/2 transition reaches 44.4 %, indicating that Nd:GdTaO4 may be an efficient laser medium at 920 nm. All the results demonstrate that Nd:GdTaO4 crystal is a good candidate for laser diode-pumped laser material.

NdFeB magnets have been fabricated from a mixture of powder NdFeB (MPQ-B+) and epoxy resins (ER) with a variation of 0% wt, 2% wt, 4% wt and 6% wt. The pellets samples were made by pressing 4 tons of the mixture powder at room temperature before curing at 100°C for 1 hour. The SEM-EDX results showed the microstructure with ER were evenly smeared the NdFeB magnetic particles due to higher percent C and lower transition metals value. Sample with 2% wt epoxy resin was able to achieve the highest density of 5.35 g/cm 3 and the highest magnetic flux of 2121 Gauss. The magnetic properties characterization using the permagraph indicates that the sample pellets with 2% wt epoxy resin has a value of remanence (Br) = 4.92 kG, coercivity (Hc) = 7.76 kOe, and energy product (Bhmax) = 4.58 MGOe. Despite low remanence value in the pellet samples, the resistance to demagnetization value was still acceptable. (paper)

Magnetic measurements and neutron powder diffraction investigation of the magnetic structure of the orthorhombic YNi{sub 4}Si-type (space group Cmmm) NdNi{sub 4}Si compound are presented. The magnetocaloric effect of NdNi{sub 4}Si is calculated in terms of the isothermal magnetic entropy change and it reaches the maximum value of –3.3 J/kg K for a field change of 50 kOe near T{sub C}=12 K. Below ∼12 K, NdNi{sub 4}Si exhibits a commensurate b-axis collinear ferromagnetic ordering with the Cmm′m magnetic space group in a zero magnetic field. At 1.5 K, the neodymium atoms have the magnetic moment of 2.37(5) μ{sub B}. The orthorhombic crystal structure and its thermal evolution are discussed in comparison with the CaCu{sub 5}-type compound. - Graphical abstract: The NdNi{sub 4}Si supplement the series of the orthorhombic derivative of the CaCu{sub 5}-type, namely the YNi{sub 4}Si-type, RNi{sub 4}Si compounds (R=Y, La, Ce, Sm, Gd–Ho). Below ∼12 K in a zero applied magnetic field, NdNi{sub 4}Si exhibits a commensurate b-axis collinear ferromagnetic ordering with the Cmm′m magnetic space group. Compared to the CaCu{sub 5}-type NdNi{sub 4}Si compound, the YNi{sub 4}Si-type counterpart has the relatively high ferromagnetic ordering temperature (9.2 K vs. 12 K), the small magnetocaloric effect (–7.3 J/kg K vs. –3.3 J/kg K for ∆H=50 kOe), and the large magnetic anisotropy at low temperatures. In contrast with CaCu{sub 5}-type NdNi{sub 4}Si, YNi{sub 4}Si-type NdNi{sub 4}Si shows distinct hysteresis loop at 2 K.We suggest that orthorhombic distortion may be used as a prospective route for optimization of permanent magnetic properties in the family of CaCu{sub 5}-type rare earth materials. - Highlights: • Below ∼12 K the YNi{sub 4}Si-type NdNi{sub 4}Si shows a ferromagnetic ordering. • MCE of NdNi{sub 4}Si reaches value of –3.3 J/kg K in 0–50 kOe near Curie point. • NdNi{sub 4}Si exhibits b-axis ferromagnetic order with the Cmm′m magnetic space

An Overview of Pending Asylum and Refugee Legislation in the US Congress

Directory of Open Access Journals (Sweden)

Melanie Nezer

2014-05-01

Full Text Available There has been no significant legislation related to the asylum process enacted in Congress in nearly a decade.  In 1996, the Illegal Immigration Reform and Immigration Responsibility Act (IIRIRA became law, rolling back protections for asylum seekers by including a one-year deadline for filing asylum applications, subjecting asylum seekers to “expedited removal” procedures, and expanding the detention of asylum seekers. In 2005, Congress enacted the REAL ID Act, which created additional legal barriers to asylum, including new requirements for proving an asylum claim. During the past several sessions of Congress, bills have been introduced that would make significant changes to the country’s asylum laws and refugee admissions program. This paper provides an overview of the pending legislation and the changes proposed.  This overview is instructive in understanding (1 which members of Congress have demonstrated interest and leadership in refugee and asylum issues; (2 which refugee and asylum reform issues have been of most interest to members of Congress in recent years; (3 the different approaches to refugee and asylum issues by members of Congress who have shown leadership on these issues; and (4 which provisions have been enacted, which have gained traction, and which remain pending without significant movement through the legislative process.While it is difficult to imagine in the current partisan climate how any asylum or refugee legislation could be enacted into law, some legislative provisions have been reintroduced over a number of sessions of Congress and some have a history of bipartisan support.  Legislation focused on a group of particular interest or concern to members of Congress could gain traction.  A more comprehensive legislative approach framed by the need generally to improve the system could be less effective, particularly in the context of the years-long stalemate on comprehensive immigration reform

Magnetic properties of melt-spun Nd-rich NdFeB alloys with Dy and Ga substitutions

Harland, C.L.; Davies, H.A.

1998-01-01

The results of a systematic investigation of the effects of Dy and Ga additions on the magnetic properties of a Nd-rich NdFeB alloy are presented and discussed. Particular attention is given to the effect of increasing Dy substitutions on the coercivity of the Nd 18 Fe 76 B 6 alloy. Substitution of 30% of the Nd by Dy resulted in a coercivity increase from 1590 to 3290 kA m -1 . However, contrary to previous suggestions, substitution of 1% of the Fe by Ga was found to have only a small influence on the magnetic properties of all the alloys in the compositional series (Nd 100-x Dy x ) 18 Fe 76 B 6 (x=0-30).

invariant 143Nd signature that is a hallmark of Réunion hotspot lavas.

Hadean silicate differentiation preserved by anomalous 142Nd/144Nd ratios in the Réunion hotspot source

Active volcanic hotspots can tap into domains in Earth’s deep interior that were formed more than two billion years ago. High-precision data on variability in tungsten isotopes have shown that some of these domains resulted from differentiation events that occurred within the first fifty million years of Earth history. However, it has not proved easy to resolve analogous variability in neodymium isotope compositions that would track regions of Earth’s interior whose composition was established by events occurring within roughly the first five hundred million years of Earth history. Here we report 142Nd/144Nd ratios for Réunion Island igneous rocks, some of which are resolvably either higher or lower than the ratios in modern upper-mantle domains. We also find that Réunion 142Nd/144Nd ratios correlate with helium-isotope ratios (3He/4He), suggesting parallel behaviour of these isotopic systems during very early silicate differentiation, perhaps as early as 4.39 billion years ago. The range of 142Nd/144Nd ratios in Réunion basalts is inconsistent with a single-stage differentiation process, and instead requires mixing of a conjugate melt and residue formed in at least one melting event during the Hadean eon, 4.56 billion to 4 billion years ago. Efficient post-Hadean mixing nearly erased the ancient, anomalous 142Nd/144Nd signatures, and produced the relatively homogeneous 143Nd/144Nd composition that is characteristic of Réunion basalts. Our results show that Réunion magmas tap into a particularly ancient, primitive source compared with other volcanic hotspots, offering insight into the formation and preservation of ancient heterogeneities in Earth’s interior.

An animal model for Norrie disease (ND): gene targeting of the mouse ND gene.

1996-01-01

In order to elucidate the cellular and molecular processes which are involved in Norrie disease (ND), we have used gene targeting technology to generate ND mutant mice. The murine homologue of the ND gene was cloned and shown to encode a polypeptide that shares 94% of the amino acid sequence with its human counterpart. RNA in situ hybridization revealed expression in retina, brain and the olfactory bulb and epithelium of 2 week old mice. Hemizygous mice carrying a replacement mutation in exon 2 of the ND gene developed retrolental structures in the vitreous body and showed an overall disorganization of the retinal ganglion cell layer. The outer plexiform layer disappears occasionally, resulting in a juxtaposed inner and outer nuclear layer. At the same regions, the outer segments of the photoreceptor cell layer are no longer present. These ocular findings are consistent with observations in ND patients and the generated mouse line provides a faithful model for study of early pathogenic events in this severe X-linked recessive neurological disorder.

High concentrations of Sr and Nd in fish teeth apatite (up to 2000 and 3800 ppm, respectively) make them relatively impervious to diagenetic overprints and allow high-precision analysis of 87 Sr/ 86 Sr and 143 Nd/ 144 Nd of very small amounts of material. 87 Sr/ 86 Sr ratios of 14 Cenozoic samples ( 87 Sr/ 86 Sr stratigraphic dating. A compilation of published 143 Nd/ 144 Nd data from recent Mn-nodules and marine Fe/Mn deposits shows that the North-Central Pacific Ocean and the major portion of the Atlantic Ocean display distinctly different, narrow ranges in isotopic compositions. Between these two areas, the 143 Nd/ 144 Nd of Mn-nodules vary systematically towards intermediate compositions in the Southern Oceans, reflecting the communication between the Atlantic and Pacific Oceans through the eastward moving Antarctic Circumpolar Current. The 143 Nd/ 144 Nd of the 2-55 Ma old fish teeth analyzed are typically close to the range of 143 Nd/ 144 Nd in Recent Mn-nodules and seawater for the respective ocean and, thus, indicate no significant change through this time period. The 143 Nd/ 144 Nd of fish teeth from the North Pacific Ocean are highest during periods of high aeolian sedimentation. (orig.)

National Acid Precipitation Assessment Program Report to Congress: An Integrated Assessment

Energy Technology Data Exchange (ETDEWEB)

Uhart, M.; et al,

2005-08-01

Under Title IX of the 1990 Clean Air Act Amendments, Congress reauthorized the National Acid Precipitation Assessment Program (NAPAP) to continue coordinating acid rain research and monitoring, as it had done during the previous decade, and to provide Congress with periodic reports. In particular, Congress asked NAPAP to assess all available data and information to answer two questions: (1) What are the costs, benefits, and effectiveness of Title IV? This question addresses the costs and economic impacts of complying with the Acid Rain Program as well as benefit analyses associated with the various human health and welfare effects, including reduced visibility, damages to materials and cultural resources, and effects on ecosystems. (2) What reductions in deposition rates are needed to prevent adverse ecological effects? This complex questions addresses ecological systems and the deposition levels at which they experience harmful effects. The results of the assessment of the effects of Title IV and of the relationship between acid deposition rates and ecological effects were to be reported to Congress quadrennially, beginning with the 1996 report to Congress. The objective of this Report is to address the two main questions posed by Congress and fully communicate the results of the assessment to decision-makers. Given the primary audience, most of this report is not written as a technical document, although information supporting the conclusions is provided along with references.

The magnetization reversal process of Nd-Fe-B nanocrystalline magnets infiltrated with Nd-Cu alloy was examined using small-angle neutron scattering (SANS). The magnetic-field dependence of SANS intensity revealed a qualitative difference between Nd-Cu-infiltrated samples and as-deformed samples. Insufficient magnetic isolation along the direction perpendicular to the nominal c-axis is expected from comparable SANS intensities for different ranges of q values along this direction. For small q values near the coercivity field, Nd-Cu-infiltrated samples show a noticeable reduction in SANS intensity along the nominal c-axis, which is parallel to the external magnetic field. This indicates less spatial fluctuation of magnetic moments in Nd-Cu-infiltrated samples, owing to magnetically isolated Nd{sub 2}Fe{sub 14}B grains.

Gao, J; Dai, X J; Zhang, L; Wu, X D

2013-01-01

We report compact diode-end-pumped continuous-wave laser operation at 1112 nm under 885 nm diode-direct pumping for the first time. On the basis of the R 2 →Y 6 transition in a conventional Nd:YAG (yttrium aluminum garnet) single crystal, the maximum output power of 12.5 W is achieved, with an optical to optical efficiency of 46.6% and a slope efficiency of 52.9%. To the best of our knowledge, this represents the highest output at 1112 nm generated by a diode-end-pumped Nd:YAG laser. Furthermore, it is the highest optical to optical efficiency ever reported for 1112 nm Nd:YAG lasers. The short term power stability is ∼0.32% at 12.0 W output. (letter)

We generated efficient blue laser output at 454 nm by intracavity frequency doubling of a continuous-wave (cw) diode-pumped Nd:YLiF(4) (Nd:YLF) laser at 908 nm based on the (4)F(3/2)-(4)I(9/2) transition. With 32.8 W of incident pump power at 880 nm and the frequency-doubling crystal LiB(3)O(5), a level as high as 4.33 W of cw output power at 454 nm is achieved, corresponding to an optical conversion efficiency of 13.2% with respect to the incident pump power. To the best of our knowledge, this is the first blue laser at 454 nm generated by intracavity frequency doubling of a diode-pumped Nd:YLF.

RUSSIAN FOREIGN POLICY AND CONGRESSES OF TROPPAU AND LAIBACH

Directory of Open Access Journals (Sweden)

Александр Владимирович Чернов

2014-12-01

Full Text Available The article describes the process of preparation and holding of congresses in Troppau and Laibach. At the beginning of 1820 there was a revolution of Spain. The Russian diplomats headed by Emperor Alexander I and J. Capodistria offered to convene the congress to develop the measures to combat the Spanish revolution. But the British and Austrians opposed that. However when Naples revolution started, Metternich requested permission for the suppression of the rebellion from Alexander I, but Russians insisted on the convocation of the conference. On the congress of Troppau the Russian delegation insisted on the development of the universal measures to the struggle against revolutions that had to be hold in a peaceful manner. The Austrians, who sought to the carrying out of one-sided armed intervention in Naples, were forced to agree with the Russian project. The Preliminary protocol was based on this project. On the congress J. Capodistria offered the new version of his project of the “universal union”. When the king of Neapolitan Ferdinand IV arrived to Laibach he immediately demanded the intervention in Naples. The Russian plan failed. Alexander I was forced to agree to the armed intervention.

AMOC Variability During the Last 400 ka from Nd Isotopes in a Southern Ocean Core

Science.gov (United States)

Lupien, R.; Pena, L.; Goldstein, S. L.

2014-12-01

Paleoceanographic studies have used Nd isotope ratios to characterize paleo-ocean deep-water mass distributions. The Southern Ocean has nearly homogeneous ɛNd that reflects the relative inputs from the north Atlantic and north Pacific, offering the possibility to quantify the AMOC strength through time. However, obtaining an ɛNd record from the Southern Ocean is a challenge because carbonates are poorly preserved there, hindering stratigraphic control and generally precluding use of this important substrate. Alternatively, studies of deep-sea corals and ferromanganese crusts provide snapshots or poor time resolution. Deep-sea core E33-22 (55°S, 120°W, 2743m) lies in the polar frontal zone of the Pacific sector, above the carbonate compensation depth, where foraminifera are preserved. It spans ~400,000 years (from the Holocene to MIS11) with a sedimentation rate of ~2.5 cm/kyr. We measured its ɛNd record with the purpose of determining the best estimate of the export of NADW out of the Atlantic system, which we suggest is our best measure of the vigor of the global thermohaline circulation system. The record shows expected ɛNd variability during orbital and sub-orbital time-scales, that is lower ɛNd during warm and higher ɛNd during cold climate intervals. Moreover, the record passes a critical test in that ɛNd-values are almost always between South Atlantic and Pacific values. The only exceptions are glacial periods when they coincide with South Atlantic values, indicating extension of Southern Ocean system into the South Atlantic. We conclude that these data represent a conservative record of AMOC variability through the late Pleistocene.

New England Energy Congress project. Final report, June 1978-July 1980

1981-11-20

From May 1978 until April 1979, 120 New Englanders volunteered for one of six committees to devise and consider energy policy recommendations for the region's twenty-five Member, six state Congressional delegation. Sponsored by the New England Congressional Caucus and Tufts University, the New England Energy Congress was funded by grants from the Economic Development Administration, US Department of Commerce and the Office of Environment, US Department of Energy. The results of the work of the 120 delegates and nine staff was a 500 page report, Blueprint for Energy Action, containing over 150 policy recommendations to the Congress, Executive agencies, state legislatures and municipalities. The New England Congressional Caucus responded in June 1979 with an Energy Package, including twenty (and ultimately twenty-five) legislative bills and several letters to federal agencies, based on the recommendations of the Energy Congress. Following the release of the report in June 1979, 55 delegates continued their efforts as members of the Implementation Group of the Energy Congress. In July 1980, this group released a volume of Strategy Papers designed to assist in the implementation of Energy Congress recommendations. As a result of this work, a broad array of energy activities were initiated in New England and in Washington. By January 1981, 20 of the 25 bills in the Caucus package had been passed in whole or in part. This final report discusses the Energy Congress' activities, consensus decision-making process and its findings. The report reviews the results of a thorough evaluation conducted through the mail and by phone of participants, outside observers and from Capital Hill. The clear conclusion is that the Energy Congress made a unique and significant contribution towards enabling New Englanders, both in the region and in Washington, to set energy goals and priorities and to begin serious efforts to reduce the region's precarious dependence on oil imports.

Diffusion process by Nd-Al and Pr-Al alloys was compared and investigated in Nd-Fe-B thin films. Enhanced coercivity 2.06T and good squareness was obtained by using Pr85Al15 and Nd85Al15 alloys as diffusion sources. But the coercivity of diffusion-processed thin films by Pr70Al30 and Pr55Al45 alloys decreased to 2.04T and 1.82T. High ambient coercivity of 2.26T was achieved in diffusion-processed thin film by Nd70Al30 leading to an improved coercivity thermal stability because Nd2Fe14B grains were enveloped by Nd-rich phase as seen by transmission electron microscopy Nd-loss image. Meanwhile, microstructure-dependent parameters α and Neff were improved. However, high content of Al in diffusion-processed thin film by Nd55Al45 lead to degraded texture and coercivity.

Temperature-dependent luminescence and temperature-stimulated NIR-to-VIS up-conversion in Nd3+-doped La2O3-Na2O-ZnO-TeO2 glasses

Science.gov (United States)

Sobczyk, Marcin

2013-04-01

Telluride glasses of the composition xNd2O3-(7-x)La2O3-3Na2O-25ZnO-65TeO2, where (0≤x≤7) were prepared by the melt quench technique. Some physical and optical properties of the glasses were evaluated. The thermal behavior i.e. glass transition and crystallization temperatures were studied by using TGA-DTA technique. Optical properties of Nd3+-doped telluride glasses were investigated between 298 and 700 K. Basing on the obtained values of J-O parameter values (×10-20 cm2: Ω2=4.49±0.84, Ω4=5.03±0.61, Ω6=4.31±0.73), the radiative transition probabilities (AT), radiative lifetimes (τR), fluorescence branching ratios (β) and emission cross-sections (σem) were calculated for the 4F3/2→4IJ/2 (where J=9, 11 and 13) transitions of Nd3+ ions. The τR value of the 4F3/2 level amount to 164 μs and is slightly higher than the measured decay time of 162 μs. With the increasing of Nd2O3 concentration from 0.5 to 7.0 mol% the experimental lifetime of the fluorescent level decreases from 162 to 5.6 μs. The estimated quantum efficiency amount to 100%, based on a comparison of τR and the experimental decay time of a slightly doped Nd3+ telluride glass. An analysis of the non-radiative decay was based on the cross-relaxation mechanisms. The 4F3/2→4I9/2 and 4F5/2→4I9/2 transitions were analyzed with respect to the fluorescence intensity ratio (FIR) and were found to be temperature dependent. Infrared-to-visible up-conversion emissions with a maximum at 603.0 and 635.3 nm were observed at high temperatures using the 804 nm excitation and are due to the 4G5/2→4I9/2 and 4G5/2→4I11/2 transitions of Nd3+ ions, respectively. The near quadratic dependence of fluorescence on excitation laser power confirms that two photons contribute to up-conversion of the orange emissions. The temperature-stimulated up-conversion excitation processes have been analyzed in detail. The optical results indicate that the investigated glasses are potentially applicable as a 1063 nm

Effect of Cu addition on coercivity and interfacial state of Nd-Fe-B/Nd-rich thin films

International Nuclear Information System (INIS)

Matsuura, M; Sugimoto, S; Fukada, T; Tezuka, N; Goto, R

2010-01-01

This study provides the effect of Cu addition on coercivity (H cJ ) and interfacial microstructure in Nd-Fe-B/Nd-rich thin films. All films were deposited by using ultra high vacuum (UHV) magnetron sputtering, and the Nd-Fe-B layer was oxidized under several atmospheres with different oxygen content. Then, the films were annealed at 250-550 0 C under UHV. The films oxidized in low vacuum (10 -2 -10 -5 Pa) (under low oxygen state) exhibited the recovery of H cJ by the annealing at 450 0 C. On the contrary, the H cJ of the films oxidized in Ar (under high oxygen state) decreased with increasing annealing temperature. However, the H cJ increased drastically at the temperatures above 550 0 C. In addition, the Cu added films, which were annealed at temperatures above 350 0 C, showed higher coercivities than the films without Cu addition. The XRD analysis suggested the existence of C-Nd 2 O 3 phase in the Cu added films annealed at 550 0 C. It can be considered that the Cu addition decreases the eutectic temperature of Nd-rich phase and influences the interfacial state between Nd 2 Fe 14 B and Nd-rich phase.

Luminescence quantum efficiency determination in LiYF4:Nd3+ using photoacoustic spectroscopy

International Nuclear Information System (INIS)

Franca, E.J.

1989-01-01

Optical properties of LiYF 4 :Nd 3+ were studied using absorption, emission, excitation and photo acoustic spectroscopies. The Nd 3+ transitions were identified and the Stark sublevels were determined for the 4 I 9/2 , 4 I 11/2 and 4 F 3/2 levels. It is also presented and analysed three methods for the luminescence quantum efficiency determination, based on parameters from the spectra mentioned above. These methods were applied to four groups centered on 517, 577, 743 and 792nm. The first method provided values too high due to its assumption that the material has only one luminescent channel. The values obtained from the second one are still somewhat high but closer to the expected ones. The superestimation can be atributed to the imprecision in the existing branching ratios values, needed in this method. The third one, developed from the other two, provided values closer to the expected ones, but also affected by experimental conditions limitations, mainly related to the spectral resolution of the photoacustic spectra. The obtained results show that this method, once improved and associated to better experimental conditions, will lead to more accurate luminescence quantum efficiency values. (author) [pt

Rock magnetic parameters and Sr-Nd isotopes as tracers of continental erosion in Red Sea and in Gulf of Aden during the last 20,000 years

Science.gov (United States)

Rojas, V.; Bouilloux, A.; Meynadier, L.; Valet, J.-P.; Joron, J.-L.

2012-04-01

Over the past 20,000 years earth climate has undergone important changes that include the transition from the last glaciation to the Holocene with the retreat of glaciers, the modification of atmospheric circulation systems and hydrologic regimes. The production and transport of matter into the ocean was influenced by these variations in climatic conditions. In this study we considered the Red Sea and the Gulf of Aden as basins that offer a particular geographic and geological setting and that could be of interest in understanding climate variations and their effects in local erosion. The study of two cores in each side of the Bab-el-Mandeb strait (MD 92-1002 in the Gulf of Aden and MD 92-1008 in the Red Sea) allows the comparison between the open ocean and a more isolated basin. Additionally, this is an intertropical region influenced by African and Asian monsoons whose intensities can vary depending on climate and wind patterns. Erosion and matter transfer from the continents to these basins in response to climate changes can be studied using different approaches including rock magnetism, sedimentology and radiogenic isotopes. Neodymium isotope ratios (expressed here in ɛNd) are a useful tracer of oceanic sediments sources and type of transport and can be used as a signature of specific water masses. The main sources of Nd in oceans are fluvial and eolian inputs originated from the erosion of the continental crust. We measured ɛNd values in both cores of the silicate and carbonate phases, which correspond respectively to detrital and dissolved Nd. We observe differences between the isotopic records of the two basins. In the Gulf of Aden detrital and dissolved ɛNd values show large changes linked to the Glacial-Interglacial transition, in agreement with other studies in the equatorial Indian Ocean. Both signals decreased by 1.5 ɛNd units between the LGM and the Holocene. By comparing these results with those from the Red Sea, we observe a less clear decrease

The Effect of Grinding and Roasting Conditions on the Selective Leaching of Nd and Dy from NdFeB Magnet Scraps

Directory of Open Access Journals (Sweden)

Ho-Sung Yoon

2015-07-01

Full Text Available The pretreatment processes consisting of grinding followed by roasting were investigated to improve the selective leaching of Nd and Dy from neodymium-iron-boron (NdFeB magnet scraps. The peaks of Nd(OH3 and Fe were observed in XRD results after grinding with NaOH as the amount of water addition increased to 5 cm3. These results indicate that the components of Nd and Fe in NdFeB magnet could be changed successfully into Nd(OH3 and Fe, respectively. In the roasting tests using the ground product, with increasing roasting temperature to 500 °C, the peaks of Nd(OH3 and Fe disappeared while those of Nd2O3 and Fe2O3 were shown. The peaks of NdFeO3 in the sample roasted at 600 °C were observed in the XRD pattern. Consequently, 94.2%, 93.1%, 1.0% of Nd, Dy, Fe were leached at 400 rpm and 90 °C in 1 kmol·m−3 acetic acid solution with 1% pulp density using a sample prepared under the following conditions: 15 in stoichiometric molar ratio of NaOH:Nd, 550 rpm in rotational grinding speed, 5 cm3 in water addition, 30 min in grinding time, 400 °C and 2 h in roasting temperature and time. The results indicate that the selective leaching of Nd and Dy from NdFeB magnet could be achieved successfully by grinding and then roasting treatments.

End pumping of solid-state lasers by single semiconductor laser diode arrays (LDAs) is efficient, but the maximum pump power is limited by the source brightness and matching the TEM/sub 00/ Nd:YAG cavity mode. To increase the output power from a solid-state Nd:YAG laser, one option is to employ a multiplicity of LDA to provide more pump power than is available from a single source. The authors report herein a 660-mW cw TEM/sub 00/ Nd:YAG laser, end-pumped by seven LDA, with bundled optical fibers coupling the light from each diode to the Nd:YAG rod end. The maximum electrical-to-optical conversion efficiency attained was 4.7% at 560-mW Nd:YAG output power. The LDAs (SDL-2430-C, 100 μm wide) were mounted on separate thermoelectric coolers to tune emission wavelength to the Nd:YAG absorption bands. The diodes were operated at their rated output power (50,000 h mean time to failure). The 110/125-μm diam 0.37-N.A. fibers were butt coupled to the lasers and glued together into a hexagonal close pack. The authors have obtained the highest average power demonstrated to date in the TEM/sub 00/ mode from a Nd:YAG laser, reliably end-pumped by multiple laser diodes with good efficiency

[Student program, congress grants and their potential influence on surgical career selection].

Science.gov (United States)

Jähne, J; Mittelstädt, A; Götzky, K

2017-11-01

Due to a decreased interest in surgical training the German Society of Surgery (GSS) has provided a specially sponsored student program at its annual clinical congress for many years in order to increase the number of applicants for a career in surgery. It remains unclear if this goal is reached because an evaluation has not yet been performed. At the clinical congress in 2014, 200 medical students participated in a special student program with the aid of a congress grant totaling 100,000 €. By means of a questionnaire it was asked how many of the participants in this special program have started a residency in surgery. Almost 17% of the participants of the student program answered and 13 students (6.5% of all participants) stated that they had started a surgical residency. All of these students claimed an interest in surgery even before participation in the congress. Those students who had not yet decided what kind of residency they should choose did not vote for surgery despite their visit to the congress. The student program and the congress grant at the annual clinical congress of the GSS do not result in an increased number of applicants for a residency in surgery. Both incentives might be not more than a strategic marketing instrument. An increased number of medical students applying for a residency in surgery is only to be expected if social developments (e. g. attention to a work-life balance) and their concomitant challenges are reflected in surgical day to day work.

Congress, courts, and commerce: upholding the individual mandate to protect the public's health.

Science.gov (United States)

Hodge, James G; Brown, Erin C Fuse; Orenstein, Daniel G; O'Keefe, Sarah

2011-01-01

Among multiple legal challenges to the Patient Protection and Affordable Care Act (PPACA) is the premise that PPACA's "individual mandate" (requiring all individuals to obtain health insurance by 2014 or face civil penalties) is inviolate of Congress' interstate commerce powers because Congress lacks the power to regulate commercial "inactivity." Several courts initially considering this argument have rejected it, but federal district courts in Virginia and Florida have concurred, leading to numerous appeals and prospective review of the United States Supreme Court. Despite creative arguments, the dispositive constitutional question is not whether Congress' interstate commerce power extends to commercial inactivity. Rather, it is whether Congress may regulate individual decisions with significant economic ramifications in the interests of protecting and promoting the public's health. This article offers a counter-interpretation of the scope of Congress' interstate commerce power to regulate in furtherance of the public's health. © 2011 American Society of Law, Medicine & Ethics, Inc.

Role of Congress in the High Level Radioactive Waste Odyssey: The Wisdom and Will of the Congress - 13096

International Nuclear Information System (INIS)

Vieth, Donald L.; Voegele, Michael D.

2013-01-01

Congress has had a dual role with regard to high level radioactive waste, being involved in both its creation and its disposal. A significant amount of time has passed between the creation of the nation's first high level radioactive waste and the present day. The pace of addressing its remediation has been highly irregular. Congress has had to consider the technical, regulatory, and political issues and all have had specific difficulties. It is a true odyssey framed by an imperative and accountability, by a sense of urgency, by an ability or inability to finish the job and by consequences. Congress had set a politically acceptable course by 1982. However, President Obama intervened in the process after he took office in January 2009. Through the efforts of his Administration, by the end of 2012, the US government has no program to dispose of high level radioactive waste and no reasonable prospect of a repository for high level radioactive waste. It is not obvious how the US government program will be reestablished or who will assume responsibility for leadership. The ultimate criteria for judging the consequences are 1) the outcome of the ongoing NRC's Nuclear Waste Confidence Rulemaking and 2) the concomitant permissibility of nuclear energy supplying electricity from operating reactors in the US.

2010-11-01

We report for the first time (to our knowledge) a diode-pumped Nd:YAG laser emitting at 869 nm based on the (4)F(3/2)-(4)I(9/2) transition, generally used for a 946 nm emission. Power of 453 mW at 869 nm has been achieved in cw operation with a fiber-coupled laser diode emitting 35.4 W at 809 nm. Intracavity second-harmonic generation in the cw mode has also been demonstrated with power of 118 mW at 435 nm by using a BiB(3)O(6) nonlinear crystal. In our experiment, we used a LiNbO(3) crystal lens to complement the thermal lens of the laser rod, and we obtained good beam quality and high output power stability.

Studies of diode-pumped solid-state lasers based on Nd:KGW and Nd:YAG

International Nuclear Information System (INIS)

Ibrahim, Akram Yousif

1996-01-01

The experimental part of the thesis was dedicated to the studies of diode-pumped solid- state lasers. it includes experiments with end-pumped continuous wave (CW) Nd-doped crystals. In particular, we have concentrated to Nd:KGW, a relatively new and not studied in the literature about the laser materials. We have performed some basics measurements of this material. A fibre bundle coupled laser diode array was used as a pump source. We have investigated two main optical arrangements for the pump, allowing operation in two regimes: 1- Low pump power operation using selected output power from a single of the fibre bundle. 2- high pump power operation using the total output power from the bundle. The main parameters of the cavities we use (e.g. the cavity mode and the pumping spot size), were determined using the matrix approach and the equations for the propagation of the Gaussian beams. The highest output power obtained in this work for Nd:KGW with a transverse electromagnetic (TEM 0 0) single-mode, continuous (CW) operation, was 400 mW for 1700 mW pumping power from the diode laser. We present also data about the performance of a diode pumped Nd:YAG crystal. Our experiment shows that Nd:KGW is a promising material of low and medium pumping power levels. (Author)

"Wandering in the Desert": The Clinch River Breeder Reactor Debate in the U.S. Congress, 1972-1983.

Science.gov (United States)

Camp, Michael

2018-01-01

The experimental Clinch River breeder reactor, approved by the U.S. Congress in 1970 for construction in East Tennessee, would have used plutonium instead of uranium. The project drew the ire of environmentalists who insisted that plutonium was too dangerous for commercial use, along with opponents of nuclear proliferation. Tennessee's representatives in Congress, however, desired the jobs that the project would create, and formed legislative coalitions to ensure continued appropriations for the project. Funding lasted until 1983, when fiscal conservatives, concerned about ballooning cost projections, joined with environmentalists to defund the breeder. Interpretations of U.S. nuclear policy in the 1980s have often revolved around the Three Mile Island meltdown's aftermath, but Clinch River was not affected by the incident. Instead, the Clinch River controversy revolved around other unrelated issues. The Clinch River story therefore offers a corrective to accounts that privilege national public opinion at the expense of other variables.

The neoproterozoic Goias magmatic arc, central Brazil: a review and new Sm-Nd isotopic data

Pimentel, Marcio Martins; Fuck, Reinhardt Adolfo; Gioia, Simone Maria Costa Lima

2000-01-01

In this study we review the main characteristics and geochronological/isotopic data of metaigneous rocks of the juvenile Neoproterozoic Goias Magmatic Arc in central Brazil. Some new Sm-Nd isotopic data are also presented for both the southern (Arenopolis) and northern (Mara Rosa) sections of the arc. In the south, granitoids of the Choupana-Turvania area yielded a Sm-Nd whole-rock isochron age of 863± 97 Ma and e Nd (T) of +4.1 T D M model ages vary between 0.94 and 1.13 Ga. Metavolcanic rocks in the Pontalina region have a Sm-Nd whole rock isochron age of 762 ± 77 Ma and e Nd (T) of +2.9. T DM values are between 0.96 and 1.10 Ga. In the northern section of the Goias Arc, mylonitic gneisses of the Serra Azul ridge, an important N30E shear zone, were investigated and have a Sm-Nd isochron age of 3058 ± 120 Ma and initial e Nd value of ca.+ 2.1. This data suggests that the Serra Azul ridge might represent either a mylonitized fragment of the Archaen terranes exposed just to the south, or the sialic basement of the Araguaia Belt supracrustal, along the eastern margin of the Amazon Craton. The geochronological data available so far indicate a long history of arc formation and amalgamation on the western margin of the Sao Francisco-Congo continent during the Neoproterozoic. The history of convergence of continental masses is partially coeval with the fragmentation of Rodinia, indicating that the western margin (present geographic reference) of that continent occupied a peripheral setting in the Rodinia super continent.

Cuocolo, Alberto; Acampa, Wanda; Varrone, Andrea; Salvatore, Marco [University of Naples Federico II, Department of Biomorphological and Functional Sciences, Napoli (Italy); Institute of Biostructures and Bioimages of the National Council of Research, Naples (Italy)

2006-03-15

The 2005 Annual Congress of the European Association of Nuclear Medicine (EANM) took place in Istanbul on October 15-19, under the chairmanship of Professor Hatice Durak. The programme was of excellent quality and represented a further step towards the achievement of a standardized EANM congress structure. A large industrial exhibition demonstrated the latest technological innovations and developments within the field. The congress was a great success: there were more than 4,000 participants, and 1,670 abstracts were received. Of these, 1,399 were accepted for oral or poster presentations, with a rejection rate of 16.2%. The original investigations presented were related to different areas of nuclear medicine, and addressed particularly advances in instrumentation and data processing, progress in radiochemistry and pharmacy, novel diagnostics and therapeutics, and new insights in well-established areas of clinical application, such as oncology, cardiology, neurology, psychiatry, endocrinology, paediatrics, nephrology, and infection and inflammation. It is noteworthy that a number of studies presented at this congress focussed on the quantitative interpretation of the imaging data and on pragmatic endpoints, such as adverse outcomes, and identified when nuclear medicine procedures achieved clinical effectiveness for patient care and management. These and many other studies presented at the congress demonstrate once more the crucial role that nuclear medicine has to play in contemporary medicine. This highlights lecture is only a brief summary of the large amount of data presented and discussed, which can be found in much greater detail in the congress proceedings book, published as volume 32, supplement 1 of the Eur J Nucl Med Mol Imaging in September 2005.

The branching of the 2+ to 0+ transition in 92Sr has been measured to 0.032(4) per 92Rb decay. It confirms an earlier measurement however discarded in nuclear data evaluations since in contradiction with accepted lower logft limits. The conflict could be solved assuming that close to half of the decay intensity, mostly as high-energy ground-state transitions, is missing in th edecay scheme.

Host cells infected by Sulfolobus turreted icosahedral virus (STIV) have been shown to produce unusual pyramid-like structures on the cell surface. These structures represent a virus-induced lysis mechanism that is present in Archaea and appears to be distinct from the holin/endolysin system described for DNA bacteriophages. This study investigated the STIV gene products required for pyramid formation in its host Sulfolobus solfataricus. Overexpression of STIV open reading frame (ORF) c92 in S. solfataricus alone is sufficient to produce the pyramid-like lysis structures in cells. Gene disruption of c92 within STIV demonstrates that c92 is an essential protein for virus replication. Immunolocalization of c92 shows that the protein is localized to the cellular membranes forming the pyramid-like structures.

Grain size effect on Sr and Nd isotopic compositions in eolian dust. Implications for tracing dust provenance and Nd model age

International Nuclear Information System (INIS)

Strontium (Sr) and neodymium (Nd) isotopic compositions enable identification of dust sources and reconstruction of atmospheric dispersal pathways. The Sr and Nd isotopic compositions in eolian dust change systematically with grain size in ways not yet fully understood. This study demonstrates the grain size effect on the Sr and Nd isotopic compositions in loess and 2006 dust fall, based on analyses of seven separated grain size fractions. The analytical results indicate that Sr isotopic ratios strongly depend on the grain size fractions in samples from all types of eolian dust. In contrast, the Nd isotopic ratios exhibit little variation in loess, although they vary significantly with grain size in samples from a 2006 dust fall. Furthermore, Nd model ages tend to increase with increasing grain size in samples from all types of eolian dust. Comparatively, Sr isotopic compositions exhibit high sensitively to wind sorting, while Nd isotopic compositions show greater sensitively to dust origin. The principal cause for the different patterns of Sr and Nd isotopic composition variability with grain size appears related to the different geochemical behaviors between rubidium (Rb) and Sr, and the similar geochemical behaviors between samarium (Sm) and Nd. The Nd isotope data indicate that the various grain size fractions in loess have similar origins for each sample. In contrast, various provenance components may separate into different grain size fractions for the studied 2006 dust fall. The Sr and Nd isotope compositions further confirm that the 2006 dust fall and Pleistocene loess in Beijing have different sources. The loess deposits found in Beijing and those found on the Chinese Loess Plateau also derive from different sources. Variations between Sr and Nd isotopic compositions and Nd model ages with grain size need to be considered when directly comparing analyses of eolian dust of different grain size. (author)

Scientific congresses have become the most expedient method to communicate novel findings on any research topic. However, an important question is whether this information will be published in peer-reviewed journals. Our aim was to determine the publication rate of the abstracts presented at the European Society for Surgery of the Shoulder and Elbow Congress and analyze factors that may influence this rate. A total of 398 abstracts reported in the Abstract Book from the 2008 European Society for Surgery of the Shoulder and Elbow Congress were examined and categorized by oral and poster presentations, topic, and the number of authors listed. A search in PubMed and Google Scholar for subsequent peer-reviewed publications was performed in September 2015. The time to publication after the meeting had been held; the type of journal and its impact factor at the time to publication were recorded for those abstracts that reached peer-reviewed journal publication. The overall publication rate for the 2008 European Society for Surgery of the Shoulder and Elbow oral and poster presentations was 45.20% after 7 years. The mean time to publication was 18.53 months, and the mean impact factor value was 2.32. Oral presentations were significantly better represented in journals than posters (64.40 vs. 35.40%, p Congress were published in peer-reviewed journals. Oral presentations with a higher number of authors had an increased likelihood of being published.

The Solvay Council, 1911: ``A kind of private congress''

Science.gov (United States)

Staley, Richard

2011-04-01

The photograph of its participants gathered around the conference table at the first Solvay Congress in physics has long presented an iconic image of physics in the early twentieth century, and the event has commonly been celebrated for its distinctive role in the propagation of quantum theory, as well as for the rich heritage in subsequent conferences that it initiated. Yet it is not often appreciated just how unusual this first congress or ``council'' was. Convened and funded by the Belgian industrialist Ernst Solvay, it was conceived and planned by the Berlin physical chemist Walther Nernst, with a zealous attention to detail that extended to entreating participants to keep its proceedings confidential until it had actually occurred. Kept private to facilitate later public notice, I will argue that this conference also helped fashion a distinctive (and selective) view of the past. This paper combines an examination of the planning and conduct of the congress with a study of the earliest uses of general concepts of ``classical'' theory from the late nineteenth century, in order to argue that the Solvay congress was important not just to the wider propagation of quantum theory, but to the formation of the conceptual framework within which we now cast this era and its physics: the contrast between classical and modern theory.

Exogenous attention enhances 2nd-order contrast sensitivity

Natural scenes contain a rich variety of contours that the visual system extracts to segregrate the retinal image into perceptually coherent regions. Covert spatial attention helps extract contours by enhancing contrast sensitivity for 1st-order, luminance-defined patterns at attended locations, while reducing sensitivity at unattended locations, relative to neutral attention allocation. However, humans are also sensitive to 2nd-order patterns such as spatial variations of texture, which are predominant in natural scenes and cannot be detected by linear mechanisms. We assess whether and how exogenous attention—the involuntary and transient capture of spatial attention—affects the contrast sensitivity of channels sensitive to 2nd-order, texture-defined patterns. Using 2nd-order, texture-defined stimuli, we demonstrate that exogenous attention increases 2nd-order contrast sensitivity at the attended location, while decreasing it at unattended locations, relative to a neutral condition. By manipulating both 1st- and 2nd-order spatial frequency, we find that the effects of attention depend both on 2nd-order spatial frequency of the stimulus and the observer’s 2nd-order spatial resolution at the target location. At parafoveal locations, attention enhances 2nd-order contrast sensitivity to high, but not to low 2nd-order spatial frequencies; at peripheral locations attention also enhances sensitivity to low 2nd-order spatial frequencies. Control experiments rule out the possibility that these effects might be due to an increase in contrast sensitivity at the 1st-order stage of visual processing. Thus, exogenous attention affects 2nd-order contrast sensitivity at both attended and unattended locations. PMID:21356228

The present study was carried out with the purpose of evaluating the clinical usefulness of radioimmunodetection (RAID) with 111 In-labeled murine/human chimeric monoclonal antibody, Nd2 (c-Nd2) in patients with pancreatic cancer. Nineteen patients suspected to have pancreatic cancer were administered intravenously 74 MBq/2 mg 111 In-labeled c-Nd2 in 100 ml of saline containing 2% albumin over 30 min. A scintigram was obtained on the 3rd day after infusion by using single photon emission computed tomography (SPECT) imaging. Of the 14 patients finally diagnosed as having pancreatic cancer on the basis of surgical specimens or progress of disease, specific focal uptake at the site of the tumor was detected in 12 (true positive cases), representing a sensitivity of 85.7% (12/14), and liver metastasis was found in one case with metastasis. Of the 5 patients diagnosed with tumor-forming pancreatitis (TFP), 4 patients demonstrated true negative imaging, but one patient whose tumor demonstrated interesting findings in histology and immunostaining, showed false positive imaging. Of patients investigated for human anti-chimeric antibody (HACA) response, none showed HACA response, and no allergic reaction was seen in any of the patients administered c-Nd2. These results suggest that RAID with 111 In-labeled c-Nd2 is useful for differential preoperative diagnosis between invasive pancreatic cancer and TFP. (author)

Altitude Stress During Participation of Medical Congress

2016-01-01

Medical congresses often held in highlands. We reviewed several medical issues associated with altitude stress especially while physicians have participated medical congress held in high altitude. Altitude stress, also known as an acute mountain sickness (AMS), is caused by acute exposure to low oxygen level at high altitude which is defined as elevations at or above 1,200 m and AMS commonly occurs above 2,500 m. Altitude stress with various symptoms including insomnia can also be experienced in airplane. AMS and drunken state share many common features in symptoms, neurologic manifestations and even show multiple microbleeds in corpus callosum and white matter on MRI. Children are more susceptible to altitude stress than adults. Gradual ascent is the best method for the prevention of altitude stress. Adequate nutrition (mainly carbohydrates) and hydration are recommended. Consumption of alcohol can exacerbate the altitude-induced impairments in judgment and the visual senses and promote psychomotor dysfunction. For prevention or treatment of altitude stress, acetazolamide, phosphodiesterase inhibitors, dexamethasone and erythropoietin are helpful. Altitude stress can be experienced relatively often during participation of medical congress. It is necessary to remind the harmful effect of AMS because it can cause serious permanent organ damage even though the symptoms are negligible in most cases. PMID:27621942

In this work, we present the spectroscopic properties of KY 3 F 10 (KY3F) nanocrystals activated with thulium and codoped with ytterbium and neodymium ions. The most important processes that lead to the thulium upconversion emissions in the blue region were identified. A time-resolved luminescence spectroscopy technique was employed to measure the luminescence decays and to determine the most important mechanisms involved in the upconversion process that populates 1 G 4 (Tm 3+ ) excited states. Analysis of the energy-transfer processes dynamics using selective pulsed-laser excitations in Yb:Nd:Tm, Nd:KY3F nanocrystals shows that the direct energy transfer from Nd 3+ to Tm 3+ ions is the mechanism responsible for the 78% of the blue upconversion luminescence in the Yb:Nd:Tm:KY3F when compared with the Yb:Nd:Tm:KY3F bulk crystal for an laser excitation at 802 nm. An investigation of the 1 G 4 level luminescence kinetic of Tm 3+ in Yb/Nd/Tm system revealed that the luminescence efficiency ( 1 G 4 ) starts with a very low value (0.38%) for the synthesized nanocrystal (as grown) and strongly increases to 97% after thermal treatment at 550 °C for 6 h under argon flow. As a consequence of the thermal treatment at T=550 °C, the contributions of the (Nd×Tm) (Up 1 ) and (Nd×Yb×Tm) (Up 2 ) upconversion processes to the 1 G 4 luminescence are 33% (Up 1 ) and 67% for Up 2 . Up 2 process represented by Nd 3+ ( 4 F 3/2 )→Yb 3+ ( 2 F 7/2 ) followed by Yb 3+ ( 2 F 5/2 )→Tm ( 3 H 4 )→Tm 3+ ( 1 G 4 ) was previously reported as the main mechanism to produce the blue luminescence in Yb:Nd:Tm:YLiF 4 and KY 3 F 10 bulk crystals. Results of X-ray diffraction analysis of nanopowder using the Rietveld method reveled that crystallite sizes remain unchanged (12–14 nm) after thermal treatments with T≤400 °C, while the 1 G 4 luminescence efficiency strongly increases from 0.38% (T=25 °C) to 12% (T=400 °C). Results shown that the Nd 3+ ions distribution has a concentration

Regulation of above-ground oil and waste containers. Hearing before the Subcommittee on Transportation, Tourism, and Hazardous Materials of the Committee on Energy and Commerce, House of Representatives, One Hundredth Congress, Second Session, January 26, 1988

Energy Technology Data Exchange (ETDEWEB)

1988-01-01

Representatives from the petroleum industry, US EPA, National Bureau of Standards and Congress were among those testifying at a hearing to discuss one of the worst inland environmental disasters in this Nation's history. The January 2 collapse of the Ashland Oil Co.'s storage tank in Floreffe, Pennsylvania resulted in the release of some 4 million gallons of diesel fuel. Approximately a million gallons escaped the containment structures and spilled over into the Monongahela River. This spill has contaminated the drinking water sources for millions of people downstream, from Pittsburgh to Cincinnati to Louisville, and beyond. Attention is focused on the causes of this tank's collapse, the response measures taken by Ashland Oil, the Coast Guard, the EPA, and the need for tighter federal regulations of above-ground tanks used for the storage of petroleum and hazardous substances.

The age and emplacement of obducted oceanic crust in the Urals from Sm-Nd and Rb-Sr systematics

International Nuclear Information System (INIS)

Edwards, R.L.; Wasserburg, G.J.

1985-01-01

The Urals contain a 2000 km belt of mafic-ultramafic bodies. The Sm-Nd and Rb-Sr systematics of two of these bodies, the Kempersai Massif in the South Ural Mountains and the Voykar-Syninsky Ophiolite Complex in the Polar Ural Mountains have been examined. These data confirm the hypothesis that these bodies represent fragments of pre-collision oceanic crust and establish constraints on the nature and timing of events in the Uralian Orogeny. Two Kempersai gabbros define Sm-Nd internal isochrons of 397 +- 20 My and 396 +- 33 My with epsilonsub(Nd)(T) = +8.7 -+ 0.6 and +8.4 -+ 1.3, respectively. Whole rock samples of pillow basalt, diabase, gabbros, troctolite, and a metasediment give Sm-Nd values which lie on this isochron indicating that these rocks are genetically related and have an igneous crystallization age of 397 My. Whole rock samples of Voykar-Syninsky diabase, gabbros, and clinopyroxenite give Sm-Nd values which lie on or within proportional 1 epsilon-unit of this isochron indicating an age and epsilonsub(Nd)(T) virtually identical to those of Kempersai. epsilonsub(Nd)(T) for the Kempersai and Voykar-Syninsky mafic samples range from +7.3 to +9.0 with an average value of +8.4. This indicates that the Urals ophiolites are derived from an ancient depleted mantle source and are most plausibly pieces of the oceanic crust and lithosphere. The fact that a metasediment has the same epsilonsub(Nd)(397 My) as the other samples indicates derivation from an oceanic source with negligible continental input. epsilonsub(Nd)(T) for the massifs is proportional 1.5 epsilon-units lower than the average for modern MORBs.

Trace-element and Sr-Nd isotopic evidence for the origin of the Sardinian fluorite mineralization (Italy)

International Nuclear Information System (INIS)

Castorina, F.; Masi, U.; Padalino, G.; Palomba, M.

2008-01-01

The fluorite-bearing hydrothermal mineralization in Sardinia mainly occurs within Paleozoic volcanic and metasedimentary rocks. Only 3 occurrences are located in volcanic and siliciclastic Cenozoic rocks. Most Sardinian fluorites exhibit relatively high rare earth and Y (REY) contents, strong positive Y anomalies, slightly negative Ce and generally positive Eu anomalies. These features indicate that the REY were mobilized mainly from non-carbonate rocks. Neither Sr nor Nd isotopes can be used to date radiometrically the Sardinian fluorites. However, the measured Sr-isotope ratios of the fluorites hosted by Paleozoic rocks fit mixing lines in the 1000/Sr versus 87 Sr/ 86 Sr plot once recalculated at 280 Ma, suggesting that the age inferred for the correction probably represents that of the formation of the fluorite mineralization. Mixing likely occurred between diluted surficial waters and brines circulating mainly through the Lower Paleozoic metasedimentary basement. The Cenozoic fluorites exhibit chemical and isotopic features similar to those of the Paleozoic fluorites, except the Nuraghe Onigu fluorite displaying a possible contribution of Sr from Cenozoic magmatic rocks. The initial ε Nd values of the Paleozoic fluorites fit the age proposed for the formation of the deposits. Moreover, the values suggest that radiogenic Nd was provided to the fluids from the Ordovician siliciclastic basement, except for 3 deposits where the potential source rocks of Nd were mainly Ordovician acidic magmatic rocks. The initial ε Nd values of the Cenozoic fluorites suggest a provenance of Nd essentially from the leaching of Variscan granitoids

Magnetisation reversal on surface of Nd-Fe-B magnets

International Nuclear Information System (INIS)

Sun, H.; Woodward, R.; Street, R.

1998-01-01

Full text: Time dependent magnetisation processes on surface of isotropic and anisotropic Nd-Fe-B magnets were measured using a Magneto-Optic Magnetometer (MOM) and the data were analysed by means of the constitutive equation H = H(M, M). The surface magnetic viscosity parameter Λ (or fluctuation field H f ) was obtained. The activation volume v, which represents the volume of a negative magnetisation nuclei during a magnetisation reversal process was calculated from Λ. The results are compared with those of the corresponding bulk properties obtained by analysing the data measured using a Vibrating Sample Magnetometer (VSM). Similar to bulk materials, Λ for the surface magnetisation is nearly constant over a wide range of magnetisation for both isotropic and anisotropic Nd-Fe-B. However, the surface hysteresis loops are significantly different from the bulk materials, indicating a significant difference in the magnetisation reversal processes between the bulk and surface materials. The surface magnetisation reversal mechanism, its relation and influence to the bulk properties and therefore the performance of permanent magnet are discussed

The ternary intermetallic compound NdPd{sub 2}Ga{sub 3} was investigated by powder neutron diffraction: the crystal structure agrees well with the ordered hexagonal PrNi{sub 2}Al{sub 3}-type structure. The antiferromagnetic ordering below T{sub N} 6.5 K corresponds to a propagation vector k = [1/2,0,0]. The ordered magnetic Nd moments of (1.99 {+-} 0.04) {mu}{sub B} at saturation lie in the basal plane due to the crystal-electric field anisotropy and are oriented perpendicular to the propagation vector.

Highlights from the UEG Week Congress 2014: New Evidence and Novel Therapies for Irritable Bowel Syndrome

Directory of Open Access Journals (Sweden)

Caroline Charles

2014-12-01

Full Text Available Irritable bowel syndrome (IBS is a common gastrointestinal disorder that affects up to 15% of the European and North American population, and is characterised by abdominal pain, bloating sensations, cramping, constipation, and diarrhoea. Main subtypes of IBS include constipation-predominant IBS (IBS-C, diarrhoea-predominant IBS (IBS-D, and mixed diarrhoea and constipation-associated IBS (IBS-M. The pathophysiology of IBS is still unclear, but important factors such as alterations in the brain-gut axis, bacterial overgrowth in the intestines, increased paracellular permeability, disruptions in the immune system, and accrued visceral sensitivity have been suggested. While many therapies are available to treat the symptoms associated with IBS, on a symptom-by-symptom basis, there are few effective treatments for IBS itself, including linaclotide, which was approved 2 years ago in Europe but only for IBS-C. Additional disease-modifying therapies to slow disease progression or achieve remission are needed as this represents a substantial unmet need. New emerging data on the pathophysiology of IBS are certainly promising; better knowledge of the underlying mechanisms will help refine the management of IBS, both in terms of diagnosis with the development of biomarkers, and in terms of therapeutic management with new pharmacological targets. Additional treatment options will be welcome given the variety of disease subtypes and presentations. The United European Gastroenterology (UEG Week Congress, which was held in Vienna, Austria, 18th-22nd October 2014, was an excellent opportunity to share new findings on the pathophysiology and new clinical evidence and emerging therapies in the management of IBS. Selected abstracts received additional exposure through the “Posters in the Spotlight” session and the “Posters of Excellence” award; such abstracts will be developed in this review.

Role of Congress in the High Level Radioactive Waste Odyssey: The Wisdom and Will of the Congress - 13096

Energy Technology Data Exchange (ETDEWEB)

Vieth, Donald L. [DOE/NVOO Project Manager for Yucca Mountain, 1982 thru 1987, 1154 Cheltenham Place, Maineville, OH 45039 (United States); Voegele, Michael D. [Nye County Nuclear Waste Repository Project Office, 7404 Oak Grove Ave, Las Vegas, NV 89117 (United States)

2013-07-01

Congress has had a dual role with regard to high level radioactive waste, being involved in both its creation and its disposal. A significant amount of time has passed between the creation of the nation's first high level radioactive waste and the present day. The pace of addressing its remediation has been highly irregular. Congress has had to consider the technical, regulatory, and political issues and all have had specific difficulties. It is a true odyssey framed by an imperative and accountability, by a sense of urgency, by an ability or inability to finish the job and by consequences. Congress had set a politically acceptable course by 1982. However, President Obama intervened in the process after he took office in January 2009. Through the efforts of his Administration, by the end of 2012, the US government has no program to dispose of high level radioactive waste and no reasonable prospect of a repository for high level radioactive waste. It is not obvious how the US government program will be reestablished or who will assume responsibility for leadership. The ultimate criteria for judging the consequences are 1) the outcome of the ongoing NRC's Nuclear Waste Confidence Rulemaking and 2) the concomitant permissibility of nuclear energy supplying electricity from operating reactors in the US.

Nd-isotopes in selected mantle-derived rocks and minerals and their implications for mantle evolution

Science.gov (United States)

Basu, A.R.; Tatsumoto, M.

1980-01-01

The Sm-Nd systematics in a variety of mantle-derived samples including kimberlites, alnoite, carbonatite, pyroxene and amphibole inclusions in alkali basalts and xenolithic eclogites, granulites and a pyroxene megacryst in kimberlites are reported. The additional data on kimberlites strengthen our earlier conclusion that kimberlites are derived from a relatively undifferentiated chondritic mantle source. This conclusion is based on the observation that the e{open}Nd values of most of the kimberlites are near zero. In contrast with the kimberlites, their garnet lherzolite inclusions show both time-averaged Nd enrichment and depletion with respect to Sm. Separated clinopyroxenes in eclogite xenoliths from the Roberts Victor kimberlite pipe show both positive and negative e{open}Nd values suggesting different genetic history. A whole rock lower crustal scapolite granulite xenolith from the Matsoku kimberlite pipe shows a negative e{open}Nd value of -4.2, possibly representative of the base of the crust in Lesotho. It appears that all inclusions, mafic and ultramafic, in kimberlites are unrelated to their kimberlite host. The above data and additional Sm-Nd data on xenoliths in alkali basalts, alpine peridotite and alnoite-carbonatites are used to construct a model for the upper 200 km of the earth's mantle - both oceanic and continental. The essential feature of this model is the increasing degree of fertility of the mantle with depth. The kimberlite's source at depths below 200 km in the subcontinental mantle is the most primitive in this model, and this primitive layer is also extended to the suboceanic mantle. However, it is clear from the Nd-isotopic data in the xenoliths of the continental kimberlites that above 200 km the continental mantle is distinctly different from their suboceanic counterpart. ?? 1980 Springer-Verlag.

Liu, G.; Xu, P.; Zhang, W.

1993-01-01

A three-dimensional partially matrixed topological model of the Nd-Fe-B ternary phase diagram has been established based on experimental results assessed comprehensively with the aid of a computer-aided design and graphic and graphics software, AutoCAD (R10), and application programs developed in this work. Vertical sections at 5.88 at.% B, Nd:B = 1:1, Fe-Nd/sub 2/Fe/sub 14/B-Nd, Nd/sub 2/Fe/sub 17/-Nd/sub 2/Fe/sub 7/B/sub 6/ have been cut out from the model and the corresponding phase relationships have been analyzed. Among them, those on the Nd-rich protons of both the sections at 5.88 at.% B and Nd:B = 2:1 and those on the Nd/sub 2/Fe/sub 14/B-Nd section are given for the first time. (author)

Absorption spectra of CsNd(MoO4)2 and CsGd(MoO4)2-Nd3+ crystals in strong magnetic fields

International Nuclear Information System (INIS)

Gorban', I.S.; Kozeeva, L.P.; Slobodyanyuk, A.V.; Shevchenko, V.A.

1987-01-01

The comparison of the electronic structure of Nd 3+ in CsNd(MoO 4 ) 2 and CsGd(MoO 4 ) 2 - Nd 3+ crystals is made. It is established that in these crystals the activator centers, mainly, of the certain type with the symmetry of the local environment C 2 are formed. The absorption spectra of self-activated CsNd(MoO 4 ) 2 crystal differ from spectra of CsGd(MoO 4 ) 2 - Nd 3+ by the presence of the vibrating structure. The Stark splittings of energy levels of Nd 3+ in the investigated crystalline matrices are more sensitive to the environment effect than the Zeeman ones. The ground state of Nd 3+ ion in CsNd(MoO 4 ) 2 and CsGd(MoO 4 ) 2 molybdates is characterized by the similar values of g-factors

Formation of defect-fluorite structured NdNiOxHy epitaxial thin films via a soft chemical route from NdNiO3 precursors.

Science.gov (United States)

Onozuka, T; Chikamatsu, A; Katayama, T; Fukumura, T; Hasegawa, T

2016-07-26

A new phase of oxyhydride NdNiOxHy with a defect-fluorite structure was obtained by a soft chemical reaction of NdNiO3 epitaxial thin films on a substrate of SrTiO3 (100) with CaH2. The epitaxial relationship of this phase relative to SrTiO3 could be controlled by changing the reaction temperature. At 240 °C, NdNiOxHy grew with a [001] orientation, forming a thin layer of infinite-layer NdNiO2 at the interface between the NdNiOxHy and the substrate. Meanwhile, a high-temperature reaction at 400 °C formed [110]-oriented NdNiOxHy without NdNiO2.

Amaral, Horacio

2003-01-01

From May 25 to 30, 2003 the beautiful city of Cancun, located in the heart of the ancient Maya Empire in Mexico, hosted the XIX ALASBIMN CONGRESS. More than 300 attendees and 80 lecturers from the American continent and Europe had the opportunity to share their knowledge and enjoy an outstanding scientific, cultural and social program. The Scientific program included reviews and original scientific papers on basic and clinical sciences as well as on new developments in diagnostic and therapeutic nuclear medicine. Cardio-vascular, neuropsychiatric, oncology, skeletal and paediatric procedures were comprehensively analysed by several experts. Introduction of new cyclotrons and modern PET and PET/CT systems in Latin America has opened new horizons for the nuclear medicine community in this sub-continent. New radiopharmaceuticals based on different peptides, receptors and gene expression dominated the scene. Reporter gene imaging of gene expression has become the first and best example of what is achievable by modern molecular imaging. Of particular interest was the presentation of novel and potential agents for radio-metabolic therapy. Additionally, in connection with the congress the IAEA organised a very successful Regional Training Course on Paediatric Nuclear Medicine with 23 participants from 11 countries. The Agency also hosted the first national project coordinators meeting of the IAEA Regional Project aimed at establishing a regional tele-nuclear medicine network in the Latin American Region in conjunction with the ALASBIMN meeting. Once again the major companies representing the nuclear medicine industry participated in the Congress and contributed to the success of the ALASBIMN meeting. In summary, attending the XIX ALASBIMN meeting was a very rewarding experience in every aspect. We are most grateful to the organisers for hosting such a nice congress. Congratulations! Now we are looking forward to participate in the next ALASBIMN Congress to be held in the

In 1933, the International Geological Congress (IGC) returned to the United States of America (USA) for its sixteenth meeting, forty-two years after the 5th IGC convened in Washington. The Geological Society of America and the U.S. Geological Survey (USGS) supplied the major part of the required extra-registration funding after the effects of the Great Depression influenced the 72th U.S. Congress not to do so. A reported 1, 182 persons or organizations, representing fifty-four countries, registered for the 16 th IGC and thirty-four countries sent 141 official delegates. Of the total number of registrants, 665 actually attended the meeting; 500 came from the USA; and fifteen had participated in the 5th IGC. The 16 th Meeting convened in the U.S. Chamber of Commerce Building from 22 to 29 July. The eighteen half-day scientific sections-orogenesis (four), major divisions of the Paleozoic (three), miscellaneous (three), batholiths and related intrusives (two), arid-region geomorphic processes and products (one), fossil man and contemporary faunas (one), geology of copper and other ore deposits (one), geology of petroleum (one), measuring geologic time (one), and zonal relations of metalliferous deposits (one)-included 166 papers, of which fifty (including several of the key contributions) appeared only by title. The Geological Society of Washington, the National Academy of Sciences, and the U.S. Bureau of Mines hosted or contributed to evening presentations or receptions. Twenty-eight of the 16th IGC's thirty new guidebooks and one new USGS Bulletin aided eight pre-meeting, seven during-meeting, and four post-meeting field trips of local, regional, or national scope. The remaining two new guidebooks outlined the USA's structural geology and its stratigraphic nomenclature. The 16th IGC published a two-volume monograph on the world's copper resources (1935) and a two-volume report of its proceedings (1936).

Reassessment of the origin of the Dun Mountain Ophiolite, New Zealand : Nd-isotopic and geochemical evolution of magma suites

International Nuclear Information System (INIS)

Sivell, W.J.; McCulloch, M.T.

2000-01-01

Magmatic suites with contrasting isotopic and geochemical compositions, sequentially emplaced in different tectonic regimes, comprise the Dun Mountain Ophiolite Belt (DMOB), New Zealand. At D'Urville Island, the northernmost exposure of the DMOB, earliest erupted (stage 1) pillow basalts ε Nd (T) = +6.3 to +7.5, and are incompatible element enriched, like basalts from geochemically anomalous ridge segments. Overlying stage 2 basalts (sheeted flows) show a narrow range of ε Nd (T) = +8.3 + or -0.2, with chemical characteristics of depleted backarc basin basalts. These rocks are intruded by mafic to silicic stage 3 magmas, which have high uniform initial 143 Nd/ 144 Nd ratios (ε Nd (T) = +9.3 + or -0.2) over a wide range of 147 Sm/ 144 Nd values (yielding a precise Early Permian Nd-isotope age of 278 ± 4 Ma (MSWD = 0.48)). Stage 3 magmas show pronounced subduction-related geochemical signatures similar to island arc tholeiites (IAT) from immature arcs. They are closely analogous to some (boninite)-IAT magmas which characterise 'infant arc' eruptive activity in forearc basins of present-day Western Pacific island arc systems. A wide variety of stage 3 magma compositions, ranging from near-primary basaltic dikes (Mg = 74) to extremely fractionated silicic plagiogranites with uniformly very depleted isotopic ratios, is consistent with slow spreading rates which gave rise to polybaric, closed-system fractionation of magmas and periodic chamber abandonment. Some stage 3 rocks with SiO 2 levels in the andesite range have low-TiO 2 contents and high Mg, and may be fractionated equivalents of boninites. High ε Nd (T) values of stage 3 magmas indicate a lack of subducted sediment with inherited crustal residence signatures, and reflect the extent of supra-subduction zone (SSZ) mantle wedge depletion. DMOB stage 3 magmas may represent foreac magmatism that was the precursor to normal subduction-related volcanism established by c. 265 Ma in the Brook Street Arc and derived

We report the first comprehensive set of high-precision 142Nd analyses for granitoids and amphibolites of the Ancient Gneiss Complex (AGC; Swaziland) and the oldest metavolcanic units of the Barberton Greenstone Belt (BGB; South Africa). The investigated samples span an age range from 3.66 Ga to 3.22 Ga and are representative of major geological units of the AGC and the lower Onverwacht Group of the BGB. Measured samples yielded μ142Nd values in the range from -8 ppm to +3 ppm relative to the JNdi-1 terrestrial standard, with typical errors smaller than 4.4 ppm. The distribution of the μ142Nd values for these 17 measured samples is bimodal with ten samples showing a tendency towards slightly negative μ142Nd anomalies, whereas seven samples have 142Nd similar to the terrestrial reference. The only confidently resolvable μ142Nd anomalies were found in a 3.44 Ga Ngwane Gneiss sample and in amphibolites of the ca. 3.45 Ga Dwalile Greenstone Remnant, revealing μ142Nd values ranging from - 7.9 ± 4.4 to - 6.1 ± 4.3 ppm. The μ142Nd deficits do not correlate with age, lithological unit, or sample locality. Instead, our results reveal that two distinct mantle domains were involved in the formation of the AGC crust. The two reservoirs can be distinguished by their μ142Nd signatures. Mantle-derived rocks tapped the enriched reservoir with negative μ142Nd at least until 3.46 Ga, whereas the granitoids preserved a negative μ142Nd signature that formed by incorporation of older AGC crust at least until 3.22 Ga. The oldest gneisses with no μ142Nd anomaly are up to 3.64 Ga in age, indicating that a modern terrestrial 142Nd reservoir was already present by early Archean times.

The members of the Nuclear Regulatory Commission (NRC) and two California members of Congress testified at a hearing to examine the decision-making capacity and the integrity of the NRC. The specific issue was whether the issuance of an operating license to the Diablo Canyon nuclear plant violated the Atomic Energy Act in the area of safety. The transcripts of closed meetings of the NRC and the expression of concern by California congressmen and a member of the NRC about the Commission's decision-making process prompted the hearings. Specific concerns were the possible avoidance of a public hearing on emergency plans in the event of an earthquake and to avoid the costs of a hearing and the quality of information used as a basis for the decision. Each member of the Commission testified in response to these concerns. The California representatives noted that Commissioners did not follow legal advice, and that they relied upon second-hand information. Other material and documents submitted for the record follows the testimony

Full Text Available Subnational studies in Mexico have pointed out the huge power of governors and the weakness of local Congresses in the design of budget policy. However, it is important to provide more evidence on the Congresses’s performance to attain a better understanding of this situation. Based on a case study of the Mexican state of Jalisco, the purposes of this paper are: a to present empirical evidence on the exercise of budgetary functions; b to explore whether the government status has an effect on the Congress behavior and its relationship with the Executive branch; and c to establish the impact of ammendments on budget policies.

Impressive Words: Linguistic Predictors of Public Approval of the U.S. Congress.

Decter-Frain, Ari; Frimer, Jeremy A

2016-01-01

What type of language makes the most positive impression within a professional setting? Is competent/agentic language or warm/communal language more effective at eliciting social approval? We examined this basic social cognitive question in a real world context using a "big data" approach-the recent record-low levels of public approval of the U.S. Congress. Using Linguistic Inquiry and Word Count (LIWC), we text analyzed all 123+ million words spoken by members of the U.S. House of Representatives during floor debates between 1996 and 2014 and compared their usage of various classes of words to their public approval ratings over the same time period. We found that neither agentic nor communal language positively predicted public approval. However, this may be because communion combines two disparate social motives (belonging and helping). A follow-up analysis found that the helping form of communion positively predicted public approval, and did so more strongly than did agentic language. Next, we conducted an exploratory analysis, examining which of the 63 standard LIWC categories predict public approval. We found that the public approval of Congress was highest when politicians used tentative language, expressed both positive emotion and anxiety, and used human words, numbers, prepositions, numbers, and avoided conjunctions and the use of second-person pronouns. These results highlight the widespread primacy of warmth over competence as the primary dimensions of social cognition.

Bartolome, F.; Parra-Borderias, M.; Blasco, J.; Bartolome, J.

2007-01-01

The evolution of the magnetic ordering of Nd with the Fe content in NdFe x Ga 1-x O 3 is studied by low-temperature specific-heat measurements for x= =0.2. Fe doping creates a distribution of internal fields on Nd, originating a Schottky contribution to the specific heat which is present for x>0. The power law followed by the low-temperature specific heat suggests a glassy behavior for x>=0.1

Neodymium-iron-boron (NdFeB) magnets have become highly desirable for modern hi-tech applications. These magnets, in general, contain two key rare earth elements (REEs), i.e., neodymium (Nd) and dysprosium (Dy), which are responsible for the very high strength of these magnets, allowing for considerable size and weight reduction in modern applications. This study aims to explore the current and future potential of a secondary supply of neodymium and dysprosium from recycling of NdFeB magnets. For this purpose, material flow analysis (MFA) has been carried out to perform the detailed mapping of stocks and flows of NdFeB magnets in Denmark. A novel element of this study is the value added to the traditionally practiced MFAs at national and/or global levels by complementing them with a comprehensive sampling and elemental analysis of NdFeB magnets, taken out from a sample of 157 different products representing 18 various product types. The results show that the current amount of neodymium and dysprosium in NdFeB magnets present in the Danish waste stream is only 3 and 0.2 Mg, respectively. However, this number is estimated to increase to 175 Mg of neodymium and 11.4 Mg of dysprosium by 2035. Nevertheless, efficient recovery of these elements from a very diverse electronic waste stream remains a logistic and economic challenge.

Ceramic Nd:YAG (cNd:YAG) materials are employed to generate 1123-nm laser. A fiber-coupled continuous-wave (CW) 808-nm diode laser is used as the pumping source. With an incident diode power of 26.1 W, a CW output power of up to 10.8 W is obtained with a 10-mm-long ceramic Nd:YAG rod (1.0 at.%-Nd-doped). The conversion efficiency from diode power to 1123-nm laser power is 41.4%. The laser performance of another 10-mm-long cNd:YAG rod with a Nd-doping concentration of 0.6 at.% is studied as a comparison

Hf-Nd isotope constraints on the origin of the Cretaceous Caribbean plateau and its relationship to the Galápagos plume

Formation of the Cretaceous Caribbean plateau, including the komatiites of Gorgona, has been linked to the currently active Galápagos hotspot. We use Hf-Nd isotopes and trace element data to characterise both the Caribbean plateau and the Galápagos hotspot, and to investigate the relationship between them. Four geochemical components are identified in the Galápagos mantle plume: two 'enriched' components with ɛHf and ɛNd similar to enriched components observed in other mantle plumes, one moderately enriched component with high Nb/Y, and a fourth component which most likely represents depleted MORB source mantle. The Caribbean plateau basalt data form a linear array in Hf-Nd isotope space, consistent with mixing between two mantle components. Combined Hf-Nd-Pb-Sr-He isotope and trace element data from this study and the literature suggest that the more enriched Caribbean end member corresponds to one or both of the enriched components identified on Galápagos. Likewise, the depleted end member of the array is geochemically indistinguishable from MORB and corresponds to the depleted component of the Galápagos system. Enriched basalts from Gorgona partially overlap with the Caribbean plateau array in ɛHf vs. ɛNd, whereas depleted basalts, picrites and komatiites from Gorgona have a high ɛHf for a given ɛNd, defining a high- ɛHf depleted end member that is not observed elsewhere within the Caribbean plateau sequences. This component is similar, however, in terms of Hf-Nd-Pb-He isotopes and trace elements to the depleted plume component recognised in basalts from Iceland and along the Reykjanes Ridge. We suggest that the Caribbean plateau represents the initial outpourings of the ancestral Galápagos plume. Absence of a moderately enriched, high Nb/Y component in the older Caribbean plateau (but found today on the island of Floreana) is either due to changing source compositions of the plume over its 90 Ma history, or is an artifact of limited sampling.

The paper studies the phase transition of ingot with the composition (Ce{sub 50}Nd{sub 50}){sub 30}Fe{sub bal}Co{sub 4}Ga{sub 0.2}B{sub 0.92} after the annealing treatment at 1050 °C. The melt-spun ribbons which is prepared by the two treatment status ingots. The phase structure and microstructure morphologies of the ingots and melt-spun ribbons were analysed and observed by XRD and SEM. It was found that the grain size of the ribbons is on the nanometer scale. The EDS results show that there are four different phases in the ingot: (CeNd){sub 2}Fe{sub 14}B, α-Fe, Ce-rich phase and Nd-rich phase. After the annealing treatment, α-Fe, Ce-rich phase, and Nd-rich phase were obviously reduced and the contents of the main phase was significantly increased in the annealed ingot compared with the unanneal treatment ingot. The VSM results show that there is a peak waist in the ribbon which is prepared by the untreated ingot. Because the ingot is uneven, the ribbons may have the secondary phase, the Hcj is 8394 Oe. But the demagnetization curves of the ribbons, which is prepared by the annealed ingot, is relatively smooth and without the soft magnetic phase and the Hcj is 12,528 Oe, which is higher than the unanneal treatment ingot. We can know that the ingot with fine organization is the key factors to preparing high-performance ribbons.

The recent progress in solar-pumped laser with Fresnel lens and Cr:Nd:YAG ceramic medium has revitalized solar laser researches, revealing a promising future for renewable reduction of magnesium from magnesium oxide. Here we show a big advance in solar laser collection efficiency by utilizing an economical Fresnel lens and a most widely used Nd:YAG single-crystal rod. The incoming solar radiation from the sun is focused by a 0.9 m diameter Fresnel lens. A dielectric totally internally reflecting secondary concentrator is employed to couple the concentrated solar radiation from the focal zone to a 4 mm diameter Nd:YAG rod within a conical pumping cavity. 12.3 W cw laser power is produced, corresponding to 19.3 W/m(2) collection efficiency, which is 2.9 times larger than the previous results with Nd:YAG single-crystal medium. Record-high slope efficiency of 3.9% is also registered. Laser beam quality is considerably improved by pumping a 3 mm diameter Nd:YAG rod.
