    1993-03-01

    Full Text Available Today is a very special day for all the graduates assembled to have a B.A. degree conferred on them. It is a day on which to celebrate the reward for hard work and for realized dreams. This is a very homogeneous group of people - in the sense that they will be receiving B.A. degrees, and for that reason it would be highly apposite to share some cherished thought and ideas about the B.A. degree.

  16. REASONS FOR STUDENT DISCONTINUATION IN ENGINEERING DEGREE COURSES OFFERED AT A DISTANCE

    Directory of Open Access Journals (Sweden)

    S. Anbahan ARIADURAI

    2009-01-01

    Full Text Available Faculty of Engineering Technology of the Open University of Sri Lanka has been offering engineering programmes at a distance for the last two decades or so. However, completion rates in Faculty of Engineering Technology are lower compared to the other faculties of the University. This paper investigates the reasons for low completion rates in the faculty and suggests ways and means to overcome this problem. The study concludes that increasing student numbers will not necessarily increase percentage of students completing the programme though the number of students completing is increased. It is found that students offering courses for the first time in the system of distance education in their academic career perform poorer because they are not conversant with distance education techniques. It is recommended that the Faculty must offer an orientation programme on distance education to all the students enrolling for the first time, before they commence their regular programmes. Further, it has been found that considerable percentage of students who obtain eligibility to sit the final examination by completing the continuous assessments do not sit the final examination. This has been found to contribute towards non-completion of programmes as students sitting the final examination in the subsequent years perform poorly in their exams. To overcome this problem, it is recommended that current practise of allowing the student to carry forward their eligibility to unlimited period of time must be disbanded.

  17. Influence of the fluorescent brightener Periblanc BA on the degree of whiteness of the knitted cotton fabric

    Directory of Open Access Journals (Sweden)

    Miljković Milena N.

    2011-01-01

    Full Text Available In this study the influence of the different fluorescent brightener Periblanc BA concentrations on the degree of knitted cotton fabric whiteness was investigated. Two consecutive experimental runs were performed. The first was the bleaching of the knitted cotton fabric with hydrogen peroxide using the methods of two and single bath exhaustion while the second was the optical bleaching with fluorescent brightener Periblanc BA using the exhaustion method. CIE Whiteness Index and Tint value were measured on the Color-Eye 3000 spectrophotometer at the standard illuminant D65 (Ice-Texicon, d/8, D65/10° while K/S values were determined using the Kubelka Munk equation. The results show that cotton fabric bleached with fluorescent brightener Periblanc BA after bleaching with hydrogen peroxide using two bath exhaustion method has higher degree of whiteness (118.8 with a reddish tint in comparison to the one bleached with hydrogen peroxide using single bath method (106.1.

  18. Effect of the graphitic degree of carbon supports on the catalytic performance of ammonia synthesis over Ba-Ru-K/HSGC catalyst

    Institute of Scientific and Technical Information of China (English)

    Wei Jiang; Ying Li; Wenfeng Han; Yaping Zhou; Haodong Tang; Huazhang Liu

    2014-01-01

    A series of high surface area graphitic carbon materials (HSGCs) were prepared by ball-milling method. Effect of the graphitic degree of HSGCs on the catalytic performance of Ba-Ru-K/HSGC-x (x is the ball-milling time in hour) catalysts was studied using ammonia synthesis as a probe reaction. The graphitic degree and pore structure of HSGC-x supports could be successfully tuned via the variation of ball-milling time. Ru nanoparticles of different Ba-Ru-K/HSGC-x catalysts are homogeneously distributed on the supports with the particle sizes ranging from 1.6 to 2.0 nm. The graphitic degree of the support is closely related to its facile electron transfer capability and so plays an important role in improving the intrinsic catalytic performance of Ba-Ru-K/HSGC-x catalyst.

    We present an analysis of crystallographic symmetry and the origin of the pseudo-cubic character of doped BiFeO{sub 3}. Specifically, barium-doped bismuth ferrite, Bi{sub 1−x}Ba{sub x}FeO{sub 3} (x = 0.05, 0.075, 0.1, 0.125), perovskite-type nanoparticles have been synthesized by implementing five modifications to the sol–gel technique (citric acid-assisted sol–gel method, ethylene glycol method, tartaric acid-assisted sol–gel method, polyvinyl alcohol–ethylene glycol method, and EDTA complexing sol–gel method) and their final pseudo-cubic character is discussed. The effect of the carboxylic groups and hydroxyl groups during synthesis is critical to obtain single phase BBFO. Fourier transform infrared spectroscopy and thermogravimetric analysis is used to study the decomposition and thermal behavior of the precursors and their relation to the final nanoparticle characteristics. X-ray diffraction analysis shows a single phase with symmetry changes for four of the five synthesis methodologies employed. Only the EDTA complexing sol–gel method, where EDTA is used as dissolver and chelating agent, is not satisfactory in all concentration ranges. Rietveld results suggest that the degree of distortion of the rhombohedral symmetry in the crystallized BiFeO{sub 3} powders decreases 12% as a result of progressive substitution of Bi{sup 3+} by Ba{sup 2+} and that there is no shift from rhombohedral to tetragonal symmetry. Magnetization properties of samples with a low-distortion rhombohedral structure show higher magnetic saturation and remanent magnetization than samples with high-distortion rhombohedral structure. - Highlights: • Ba–BiFeO{sub 3}: rhombohedral distortion degree is highly affected by the chemical method. • Rietveld results show no shift in BBFO from rhombohedral to tetragonal symmetry. • The low-distortion rhombohedral structure show higher magnetic saturation. • To stabilize a metal complex is necessary a balance between COOH{sup

  14. Rapid preparation of ultrafine BaSO{sub 3} by SO{sub 2} storage material

    2017-01-15

    In this work, a green and efficient process was developed for the preparation of ultrafine BaSO{sub 3} with layered nanostructure surface via the reaction of BaCl{sub 2} with a SO{sub 2} storage material (SO{sub 2}SM) at room temperature. The absorption of SO{sub 2} with equimolar ethylenediamine (EDA) and ethylene glycol (EG) afforded SO{sub 2}SM, which not only offered alkyl sulfite but also released EDA and EG that served as efficient surfactants to promote the formation of BaSO{sub 3} with spherical morphology and porous structure in the process of synthesis of ultrafine BaSO{sub 3}. The factors affecting the morphology and size of BaSO{sub 3} particle were assessed by investigating the effects of SO{sub 2}SM concentration, BaCl{sub 2} concentration, stirring time and speed. It was found that a higher SO{sub 2}SM concentration led to a higher degree of supersaturation, and the particle size of BaSO{sub 3} could be reduced by increasing SO{sub 2}SM concentration. Moreover, under the identified optimal reaction conditions, ultrafine BaSO{sub 3} was obtained with an average diameter of 450 nm. In addition, a plausible formation process of BaSO{sub 3} was proposed to explain the observed reaction results. Overall, the developed process in this work provides an efficient method for the capture, utilization, and conversion of SO{sub 2} into a valuable chemical.

  12. Nanogenerator power output: influence of particle size and crystallinity of BaTiO3

    Science.gov (United States)

    Nutal Schädli, Gian; Büchel, Robert; Pratsinis, Sotiris E.

    2017-07-01

    Lead-free piezoelectric nanogenerators made with BaTiO3 offer an attractive energy harvesting solution towards portable, battery-free medical devices such as self-powered pacemakers. Here, we assembled nanogenerators made of thin, flexible poly(vinylidene fluoride-co-hexafluoropropylene) films containing either polycrystalline BaTiO3 nanoparticles of various sizes or commercial monocrystalline particles of 64 or 278 nm in average diameter. The nanoparticles were prepared by hydrogen-driven flame aerosol technology and had an average diameter of 24-50 nm with an average crystal size of about 10 nm. The rapid cooling during nanoparticle formation facilitated the synthesis of polycrystalline, multi-domain, piezoelectrically active tetragonal BaTiO3 with a high c/a lattice ratio. Using these particles, 2 μm thin polymer nanocomposites were formed, assembled into nanogenerators that exhibited a 1.4 V time-averaged output, almost twice that of the best commercial BaTiO3 particles. That output was maintained stable for over 45 000 cycles with each cycle corresponding to a heartbeat of 60 bpm. The exceptional piezoelectric performance of these nanogenerators is traced to their constituent polycrystalline nanoparticles, having high degree of domain orientation upon poling and exhibiting the flexoelectric effect, polarization induced by a strain gradient.

    A study of electroluminescence in BaFCl single crystals as a function of temperature is reported. At an excitation voltage of 5 kV, electroluminescent intensity, which is feeble at room temperature, is shown to increase with decreasing temperature. The increase is rapid between 250 K and 175 K and levels off as 80 K is approached. A tentative explanation, in the light of x-ray induced luminescence, is offered. (U.K.).

  11. New Spectroscopy at BaBar

    Energy Technology Data Exchange (ETDEWEB)

    Mazzoni, M.A.; /INFN, Rome

    2007-04-18

    The Babar experiment at the SLAC B factory has accumulated a high luminosity that offers the possibility of systematic studies of quarkonium spectroscopy and of investigating rare new phenomena. Recent results in this field are presented. In recent times spectroscopy has become exciting again, after the discovery of new states that are not easily explained by conventional models. States such as the X(3872) and the Y(4260) could be new excited charmonium states, but require precise measurements for positive identification. The BaBar experiment [1] is installed at the asymmetric storage ring PEP-II. 90% of the data accumulated by BaBar are taken at the Y(4S) (10.58 GeV) and 10% just below (10.54 GeV). The BaBar detector includes a 5-layer, double-sided silicon vertex tracker and a 40-layer drift chamber in a 1.5 T solenoidal magnetic field, which detect charged particles and measures their momenta and ionization energy losses. Photons, electrons, and neutral hadrons are detected with a CsI(Tl)-crystal electromagnetic calorimeter. An internally reflecting ring-imaging Cherenkov is also used for particle id. Penetrating muon and neutral hadrons are identified by an array of resistive-plate chambers embedded in the steel of the flux return. The detector allows good track and vertex resolution, good particle id and good photon detection so it is especially suited for spectroscopy studies.

  14. Virtual Reality System Offers a Wide Perspective

    Science.gov (United States)

    2008-01-01

    Robot Systems Technology Branch engineers at Johnson Space Center created the remotely controlled Robonaut for use as an additional "set of hands" in extravehicular activities (EVAs) and to allow exploration of environments that would be too dangerous or difficult for humans. One of the problems Robonaut developers encountered was that the robot s interface offered an extremely limited field of vision. Johnson robotics engineer, Darby Magruder, explained that the 40-degree field-of-view (FOV) in initial robotic prototypes provided very narrow tunnel vision, which posed difficulties for Robonaut operators trying to see the robot s surroundings. Because of the narrow FOV, NASA decided to reach out to the private sector for assistance. In addition to a wider FOV, NASA also desired higher resolution in a head-mounted display (HMD) with the added ability to capture and display video.

O objetivo deste trabalho foi avaliar a disponibilidade de K em solos com graus de desenvolvimento pedogenético diferentes, por meio da extração de K dos solos com diferentes extratores e com plantas de milho. Foram coletadas amostras da camada de 0 a 30 cm de 12 solos representativos do Estado da Paraíba, sendo seis mais desenvolvidos e seis menos desenvolvidos. Em três repetições de todos os 12 solos, foram aplicadas cinco doses de K (0, 50, 100, 200 e 300 mg dm-3, na forma de KCl p.a. em solução, e incubadas durante 21 dias. Após esse período, uma subamostra de cada solo foi retirada para determinação dos teores de K disponível pelos extratores Mehlich-1, Mehlich-3 e resina de troca iônica. Em seguida, os solos foram cultivados com milho em casa de vegetação durante 30 dias, e depois avaliaram-se a produção de matéria seca e o teor de K na planta. Os extratores Mehlich-1, Mehlich-3 e a resina de troca iônica extraíram teores semelhantes de K nos solos mais desenvolvidos. No grupo de solos menos desenvolvidos, os extratores Mehlich-1 e Mehlich-3 extraíram teores semelhantes de K, mas bem maiores que os de K extraídos pela resina de troca iônica, especialmente naqueles com maior teor de argila e maior proporção de minerais do tipo 2:1. Ao contrário dos extratores Mehlich-1 e Mehlich-3, nos solos menos desenvolvidos a resina de troca iônica não apresentou boa correlação com o teor de K trocável. Neste grupo de solos, o extrator Mehlich-1 foi o que mostrou melhor correlação com o conteúdo de K na planta. Na maioria dos solos, a produção de matéria seca da planta não aumentou com o aumento das doses de K, porém em todos eles houve aumento do teor de K na planta em resposta à adubação pot

    The paramagnetic radicals formed in the TL phosphors BaSO{sub 4}:Eu and BaSO{sub 4}:Eu, P have been studied using the technique of ESR. Two radicals assigned to SO{sub 2}{sup -}, were observed at room temperature. One of them exhibits a hyperfine interaction with a nearby cation. Step annealing measurements suggest a connection between these radicals and the TL glow peaks at 170 and 215 degrees C. Co-doping BaSO{sub 4}:Eu with phosphorus enhanced its TL efficiency. ESR and fluorescence emission measurements indicate that the enhancement results from an increased intake of divalent europium into the lattice. (author)

    Our previous article Safety Standards for Gua sha (press-stroking) and Baguan (cupping) discussed the risk of transfer of blood-borne pathogens with Gua sha and Ba guan, identified Gua sha and Ba guan 'instrument criticality' as semi-critical and offered recommendations for safe practice based on hospital disinfection standards. Based on the article's feedback, we feel the need to clarify that Gua sha and Ba guan instruments, if intended for reuse, must undergo high level disinfection (HLD) or, in the case of 'wet-cupping', sterilization. We update our recommendations to be amenable to both private practice and education settings.

  5. Ba isotopic signature for early differentiation between Cs and Ba in natural fission reactors

    Science.gov (United States)

    Hidaka, Hiroshi; Gauthier-Lafaye, François

    2008-08-01

    Ba isotopic studies of the Oklo and Bangombé natural fission reactors in east Gabon provide information on the geochemical behavior of radioactive Cs ( 135Cs and 137Cs) in a geological medium. Large isotopic deviations derived from fissiogenic Ba were found in chemical leachates of the reactor uraninites. The fissiogenic Ba isotopic patterns calculated by subtracting the non-fissiogenic component are classified into three types that show different magnifications of chemical fractionation between Cs and Ba. In addition, the isotopic signatures of fissiogenic 135Ba, 137Ba and 138Ba suggest an early differentiation between Cs and Ba of less than 20 years after the production of fissiogenic Cs and Ba. On the other hand, only small excesses of 135Ba ( ɛ < +1.8) and/or 137Ba ( ɛ < +1.3) were identified in some clay samples, which might have resulted from selective adsorption of 135Cs and 137Cs that migrated from the reactors by differentiation.

    BaTi4O9-doped Ba0.6Sr0.4TiO3 (BST) composite ceramics were prepared by the conventional solid-state reaction and their structure, dielectric nonlinear characteristics and microwave dielectric properties were investigated. The secondary phase of the orthorhombic structure Ba4Ti13O30 is formed among BST composite ceramics with the increase of BaTi4O9. At the same time, a duplex or bimodal grains size distribution shows fine grains in a coarse grain matrix. The degree of frequency dispersion of dielectric permittivity below Tm is increased initially and then decreased with respect to BaTi4O9. As the BaTi4O9 content increases, the tunability of composite ceramics decreases, while the Q value increases. Inter-estingly, 70 wt% BaTi4O9-doped BST has a tunability -4.0% (under 30 kV/cm biasing) versus a permit-tivity ~68 and quality factor ~134.1 (at ~3.2 GHz).

    Single crystals of the title compounds were prepared using a BaCl 2 flux and investigated by X-ray diffraction methods using Mo Kα radiation and a charge coupled device (CCD) detector. The crystal structures of these two new compounds were solved and refined in the hexagonal symmetry with space group P6 3/ mmc, a=5.851(1) Å, c=25.009(5) Å, ρcal=4.94 g cm -3, Z=2 to a final R1=0.069 for 20 parameters with 312 reflections for Ba 5Ru 2Cl 2O 9 and space group P 3¯m1 , a=5.815(1) Å, c=14.915(3) Å, ρcal=5.28 g cm -3, Z=1 to a final R1=0.039 for 24 parameters with 300 reflections for Ba 6Ru 3Cl 2O 12. The structure of Ba 5Ru 2Cl 2O 9 is formed by the periodic stacking along [001] of three hexagonal close-packed BaO 3 layers separated by a double layer of composition Ba 2Cl 2. The BaO 3 stacking creates binuclear face-sharing octahedra units Ru 2O 9 containing Ru(V). The structure of Ba 6Ru 3Cl 2O 12 is built up by the periodic stacking along [001] of four hexagonal close-packed BaO 3 layers separated by a double layer of composition Ba 2Cl 2. The ruthenium ions with a mean oxidation degree +4.67 occupy the octahedral interstices formed by the four layers hexagonal perovskite slab and then constitute isolated trinuclear Ru 3O 12 units. These two new oxychlorides belong to the family of compounds formulated as [Ba 2Cl 2][Ba n+1 Ru nO 3 n+3 ], where n represents the thickness of the octahedral string in hexagonal perovskite slabs.

    Promotional offers on cigarettes (e.g., dollar-off, multipack discounts) composed the largest share of tobacco industry marketing expenditures, totaling $8.9 billion, or 72% of the total budget in 2002. Internal industry documents indicate that young adults, potential quitters, and other price-sensitive groups are the targets of these marketing tactics. How effective they are in actually reaching these groups in the general population of smokers has not yet been investigated. Data were from 4618 current smokers responding to the large, random-digit-dialed population-based 2002 California Tobacco Survey. The characteristics were identified of smokers who reported that they used these offers "every time I see one." Thirty-five percent of smokers used promotional offers every time they saw one. Multivariate analyses identified young adults, women, African Americans, those with higher daily cigarette consumption, and those worried about cigarette costs as more likely to use promotional offers at every opportunity. Smokers most committed to quitting were no more likely to use promotional offers than those with no intention to quit. Cigarette brand was highly correlated with age and race/ethnicity, and therefore was not included in the multivariate analysis. Those who smoked menthol cigarettes and Camels, more often young adults and African Americans, were much more likely than those of other brands to use promotional offers. With the exception of smokers intending to quit, cigarette promotional offers are effectively reaching most industry-targeted groups. Importantly, young adults, who have the greatest long-term customer potential, are responding.

  10. The ultimatum game: Discrete vs. continuous offers

    Dishon-Berkovits, Miriam; Berkovits, Richard

    2014-09-01

    In many experimental setups in social-sciences, psychology and economy the subjects are requested to accept or dispense monetary compensation which is usually given in discrete units. Using computer and mathematical modeling we show that in the framework of studying the dynamics of acceptance of proposals in the ultimatum game, the long time dynamics of acceptance of offers in the game are completely different for discrete vs. continuous offers. For discrete values the dynamics follow an exponential behavior. However, for continuous offers the dynamics are described by a power-law. This is shown using an agent based computer simulation as well as by utilizing an analytical solution of a mean-field equation describing the model. These findings have implications to the design and interpretation of socio-economical experiments beyond the ultimatum game.

    Full Text Available Consumer satisfaction is imperative to a successful business, the reason for the choice of topic for this paper being explained thereby. Market changes have resulted in consumer’s enormous growth of power, which was recognized by many companies who adapted their business to meeting those expectations. Adaptation, however, also resulted in the need for constant measuring and evaluation. According to the above-mentioned, this paper measures consumer satisfaction with the product offer of the drugstore chain X The survey results have shown that X’s offer has not completely come up to the expectations of a smaller number of interviewees. In relation to the measuring ranks of consumer satisfaction defined, the greatest number of consumers has turned out to be satisfied with the product offer, whereas the percentage of those who find it excellent is smaller than the percentage of those who assess it as average.

    Fluctuation properties have been analysed for the energy levels predicted by IBFM calculations in the Ba isotopes {sup 121}Ba to {sup 131}Ba. The results indicate, in general, a situation which is close to the chaotic limit. For the lighter isotopes studied (121 and 123), a phase transition is obtained in the low-spin, positive parity states, from a situation close to regularity at low excitation energies, towards chaoticity at higher excitations.

    2017-07-31

    Depression in adolescence is a common and serious mental health problem. In the UK, access to evidence-based psychological treatments is limited, and training and employing therapists to deliver these is expensive. Brief behavioural activation for the treatment of depression (BATD) has great potential for use with adolescents and to be delivered by a range of healthcare professionals, but there is limited empirical investigation with this group. To adapt BATD for depressed adolescents (Brief BA) and conduct a pilot study to assess feasibility, acceptability and clinical effectiveness. Twenty depressed adolescents referred to the local NHS Child and Adolescent Mental Health service (CAMHs) were offered eight sessions of Brief BA followed by a review around one month later. Self- and parent-reported routine outcome measures (ROMs) were collected at every session. Nineteen of the 20 young people fully engaged with the treatment and all reported finding some aspect of Brief BA helpful. Thirteen (65%) required no further psychological intervention following Brief BA, and both young people and parents reported high levels of acceptability and satisfaction with the approach. The pre-post effect size of Brief BA treatment was large. Brief BA is a promising innovation in the treatment of adolescent depression. This approach requires further evaluation to establish effectiveness and cost effectiveness compared with existing evidence-based treatments for adolescent depression. Other questions concern the effectiveness of delivery in other settings and when delivered by a range of professionals.

  2. Hand dryer noise in public restrooms exceeds 80 dBA at 10 ft (3 m).

    2015-01-01

    High airflow hand dryers are found in many public restrooms today. These dryers offer quick and clean hand drying, and are seen as being an environment-friendly alternative to paper towels. However, many new hand dryers are loud, exposing individuals using the facilities as well as those employees who clean the facilities to potentially dangerous noise. Prolonged exposure to high levels of occupational noise can cause damage to hair cells in the cochlea, resulting in varying degrees of noise-induced hearing loss. This study examined the intensity (in dBA) of the noise produced by the air dryers in campus restrooms. Hand dryer peak and average noise was measured with a sound level meter at 2.5 ft, 5 ft, and 10 ft from the dryer. Noise measurements did not decrease as predicted by the inverse-square law, probably because of the reverberative surfaces found in the restrooms. The small sample of hand dryers tested was mostly found to be producing more noise than the manufacturer claimed they would; indeed, none of the dryers would be safe for an 8-h workday exposure. While hand dryers do reduce paper trash, they pose as a different sort of hazard to our environment and population.

    2016-04-01

    To study the damping capacity of BaTiO$_3$/Al composites, Al composites reinforced with BaTiO$_3$ powder (average grain sizes: 100 and 1000 nm) were fabricated by the hot-pressing sintering method. The damping properties of pure Al and BaTiO$_3$/Al composites were investigated and compared based on the dynamic mechanical analysis over a wide range of temperatures (50–285$^{\\circ}$C). Compared with pure Al matrix, 1000 nm BaTiO$_3$/Al composites with 5 and 10% mass fractions of BaTiO$_3$ exhibited better damping capacity. For 100 nm BaTiO$_3$/Al composite, its damping capacity is slightly higher than that of pure Al below 145$^{\\circ}$C, while it becomes lower above this degree. The damping capacity enhancement of BaTiO$_3$/Al composites can be explained by the ferroelastic domain damping. Furthermore, 5 and 10% BaTiO$_3$/Al composites have higher bending strength and hardness than pure Al sample.

    1998-01-01

    The BaBar experiment at the Stanford Linear Accelerator Center is designed to perform a search for CP violation by analysing the decays of a very large sample of B and Bbar mesons produced at the high luminosity PEP-11 accelerator. The data acquisition system must cope with a sustained high event rate, while supporting real time feature extraction and data compression with minimal dead time. The BaBar data acquisition system is based around a common VME interface to the electronics read-out of the separate detector subsystems. Data from the front end electronics is read into commercial VME processors via a custom "personality card" and PCI interface. The commercial CPUs run the Tornado operating system to provide a platform for detector subsystem code to perform the necessary data processing. The data are read out via a non-blocking network switch to a farm of commercial UNIX processors. Careful design of the core data acquisition code has enabled us to sustain events rates in excess of 20 kHz while maintaini...

    Full Text Available Purpose of the article: The aim of the paper is to uncover ways of managing service offering provid-ed by electrical equipment manufactures in the Czech Republic. The segment is extremely important for Czech industry nowadays, especially because of many companies being subcontractors for the car industry and mechanical engineering. The producers of electric equipment comply with the Czech in-dustry classification CZ-NACE 27. Methodology/methods: The questionnaire in the form of the Likert scale was prepared to gather in-formation about customer services. The respondents were usually directors or managers, e.g. employ-ees with high competencies of knowing customer services in this particular market. The total of 22 companies were included in the survey. Research was focused on the following industries classifica-tions belonging to CZ-NACE 27: CZ-NACE 27, CZ-NACE 271 and CZ-NACE 273. According to Czech Statistical Office the total number of companies belonging to these 3 segments is 136. It means 16,2 % companies belonging to CZ-NACE 27 participated in our research. Basic statistical methods were used to analyse the complete database. Scientific aim: The paper deals with the problem of service offering provided by today’s manufactur-ers. Global understanding of services that manufacturers really develop, sell, deliver and manage is still limited. Findings: Managing service offering provided by today‘s manufacturers shows that 1 Manufacturers not offer only tangible products, but also wide range of services and even information and support. 2 New products are not designed only according to company technicians, but also according to their cus-tomers. Their products and services are developed, tested and improved according to their needs. 3 Services provide complex customer care from time product selection to its end. Conclusions: Manufacturers of tangible products need to enlarge their product offering to be able to satisfy customers. Therefore

    The new barium nitridoosmate oxide (Ba(6)O)(OsN(3))(2) was prepared by reacting elemental barium and osmium (3:1) in nitrogen at 815-830 degrees C. The crystal structure of (Ba(6)O)(OsN(3))(2) as determined by laboratory powder X-ray diffraction (R3, No 148: a = b = 8.112(1) A, c = 17.390(1) A, V = 991.0(1) A(3), Z = 3), consists of sheets of trigonal OsN(3) units and trigonal-antiprismatic Ba(6)O groups, and is structurally related to the "313 nitrides" AE(3)MN(3) (AE = Ca, Sr, Ba, M = V-Co, Ga). Density functional calculations, using a hybrid functional, likewise indicate the existence of oxygen in the Ba(6) polyhedra. The oxidation state 4+ of osmium is confirmed, both by the calculations and by XPS measurements. The bonding properties of the OsN(3)(5-) units are analyzed and compared to the Raman spectrum. The compound is paramagnetic from room temperature down to T = 10 K. Between room temperature and 100 K it obeys the Curie-Weiss law (mu = 1.68 mu(B)). (Ba(6)O)(OsN(3))(2) is semiconducting with a good electronic conductivity at room temperature (8.74x10(-2) ohms(-1) cm(-1)). Below 142 K the temperature dependence of the conductivity resembles that of a variable-range hopping mechanism.

    Soares, T.; Pinson, P.; Morais, H.

    2016-09-01

    The increasing penetration of wind generation in power systems to fulfil the ambitious European targets will make wind power producers to play an even more important role in the future power system. Wind power producers are being incentivized to participate in reserve markets to increase their revenue, since currently wind turbine/farm technologies allow them to provide ancillary services. Thus, wind power producers are to develop offering strategies for participation in both energy and reserve markets, accounting for market rules, while ensuring optimal revenue. We consider a proportional offering strategy to optimally decide upon participation in both markets by maximizing expected revenue from day-ahead decisions while accounting for estimated regulation costs for failing to provide the services. An evaluation of considering the same proportional splitting of energy and reserve in both day- ahead and balancing market is performed. A set of numerical examples illustrate the behavior of such strategy. An important conclusion is that the optimal split of the available wind power between energy and reserve strongly depends upon prices and penalties on both market trading floors.

    2006-01-01

    @@ We calculate the band structure of BaS using the local density approximation and the GW approximation (GWA),i.e. in combination of the Green function G and the screened Coulomb interaction W. The Ba 4d states are treated as valence states. We find that BaS is a direct band-gap semiconductor. The result shows that the GWA band gap (Eg-Gw = 3.921 eV) agrees excellently with the experimental result (Eg-EXPT = 3.88 eV or 3.9eV).

    1989-07-03

    An Auger electron spectroscopy study has been made of the depth profiles of films of Y-Ba-Cu-O compounds. The films were produced by electron beam and ion plasma sputtering onto various substrate types. The specimens were annealed in air at temperatures ranging between 450 and 900 /degree/C. The effective diffusion coefficients for the film and substrate constituents have been estimated. The depth profiles of films annealed at 600 /degree/C reveal composition oscillations in the region adjacent to the surface. These composition oscillations are assumed to arise from the phase transformations that occur at 600 /degree/C in films of the Y-Ba-Cu-O system.

    Full Text Available Tourism is an opportunity for people from different cultures to meet and interact, to exchange ideas, traditions and ways of thinking. In this industry it is very easy to judge a person just after taking an overall look and studying her general behavior. The aim of this article is to determine the intercultural issues that can show up during the tourist act, while people belonging to different cultures interact. The research method used for creating this article is documentary study. The tourist offer shall be adapted to different types of tourist, taking into consideration some aspects as tourists’ behavior, the type of tourism they prefer and, most of all, the culture they belong to and the culture of the people from the place they visit. Despite the immense diversity of our minds, there is a structure that can serve as a basis for mutual understanding.

    The tetragonal BaTiO(3) nanopowder is synthesized in a solvent-less, efficient process by the thermolysis of a single [Ba(2)Ti(2)(thd)(4)(OnPr)(8)(nPrOH)(2)] precursor in a closed reactor at 700 degrees C under autogenous pressure, followed by combustion. This paper compiles the synthesis of the [Ba(2)Ti(2)(thd)(4)(OnPr)(8)(nPrOH)(2)] precursor, its analysis by mass spectrometry, and implementation for the fabrication of dielectric tetragonal BaTiO(3) nanopowder by controlled efficient thermal decomposition. The as-prepared, intermediate, and final forms of the obtained nanomaterials are systematically analysed by XRD, Raman, and EDS measurements to gain structural and compositional information. Employing HR-SEM, TEM, and HR-TEM techniques, the morphological changes during the structural evolution of all the phases are pursued. The mechanistic elucidation for the fabrication of BaTiO(3) nanopowder is developed on the basis of TGA and DTA data obtained for the initial [Ba(2)Ti(2)(thd)(4)(OnPr)(8)(nPrOH)(2)] reactant as well as the as-prepared BaCO(3) with amorphous Ti phase.

    Five new compounds belonging to the ABaMQ4 family were synthesized by solid-state chemistry at 1123 K. The compounds RbBaPS4, CsBaPS4, CsBaVS4, RbBaVSe4, and CsBaVSe4 are isostructural and have the TlEuPS4 structure type. They crystallize in space group D162h - Pnma of the orthorhombic system. Their structure consists isolated MQ4 tetrahedra separated by A and Ba atoms to form a salt-like structure. Density Functional Theory (DFT) calculations of the electronic structures with the use of the HSE functional suggest that the compounds are semiconductors with calculated band gaps of 3.3 eV (RbBaPS4), 3.4 eV (CsBaPS4), 2.3 eV (CsBaVS4), and 1.6 eV (RbBaVSe4).

    Polycrystalline specimens of barium uranate, BaUO4, were prepared and several properties such as the thermal expansion coefficient, elastic moduli, thermal conductivity, and Debye temperature were evaluated. The sintered specimens had a single-phase orthorhombic structure and were crack-free. The elastic moduli of BaUO4 were determined from the longitudinal and shear sound velocities and from micro-indentation tests. The Debye temperature was also determined from the sound velocities and lattice parameter measurements. The thermal conductivity of BaUO4 was calculated from the measured density at room temperature, literature values of heat capacity, and thermal diffusivity measured by the laser flash method in vacuum. The thermophysical properties of BaUO4 were examined and compared with literature data for other barium ternary oxides and SrUO4.

    The luminescence spectra and decay characteristics of both 5.45 and 3.4 eV bands in BaFCl oxygen-free crystals were investigated at 5-300 K temperature range using vacuum ultraviolet excitation as well as X-ray excitation. The similarities with excitons in alkali halides allow us to consider both excitons in BaFCl as on-center excitons and strong off-center excitons.

  12. Self-contained cable systems offer advantages

    Energy Technology Data Exchange (ETDEWEB)

    Morello, A.S.; Occhini, E.

    1977-05-01

    Low-pressure oil-filled (LPOF) cable systems, while seldom used in this country, have several advantages of interest to engineers. Less oil and insulating paper is required for low-pressure than for the more commonly used high-pressure systems because of the single core. The lower pessure offers safety features in the event of accidental oil loss. LPOF cables are used internationally because of their good thermal characteristics. Applications besides ac transmission lines include underground and submarine cables, such as those connecting islands with mainland facilities. Cooling can be accomplished either by circulating oil inside the central duct or circulating water through parallel nonmetallic pipes. Forced-cooling of the LPOF cables is less complicated, which allows them to have higher current ratings and makes them more adaptable to thermal transients. Conductor cooling, which increases capacity but prohibits overloads in LPOF cables, is the only system available to high voltage (HVDC) cables. Several experimental and demonstration cable systems are described. (DCK)

  13. What Has Literature to Offer Computer Science?

    Directory of Open Access Journals (Sweden)

    Mark Dougherty

    2004-04-01

    Full Text Available In this paper I ask the question: what has literature to offer computer science? Can a bilateral programme of research be started with the aim of discovering the same kind of deep intertwining of ideas between computer science and literature, as already exists between computer science and linguistics? What practical use could such results yield? I begin by studying a classic forum for some of the most unintelligible pieces of prose ever written, the computer manual. Why are these books so hard to understand? Could a richer diet of metaphor and onomatopoeia help me get my laser printer working? I then dig down a little deeper and explore computer programs themselves as literature. Do they exhibit aesthetics, emotion and all the other multifarious aspects of true literature? If so, does this support their purpose and understandability? Finally I explore the link between computer code and the human writer. Rather than write large amounts of code directly, we encourage students to write algorithms as pseudo-code as a first step. Pseudo-code tells a story within a semi-formalised framework of conventions. Is this the intertwining we should be looking for?

    Full Text Available Industrial heritage has a great importance in development of tourism of Tuzla Canton because this is a region which had well developed industry in the past. Major part of this industry has been destroyed and now can be used for touristic purposes Besides this function, industrial plants can be used for development of culture, education, etc., and we already have such positive examples in wealthier European countries. The aim of the survey was to examine the opinion of tourist agencies, which are providers of tourist services, on further development of tourism in the region of Tuzla Canton, with special emphasis on industrial tourism, because tourist agencies are one of the key factors in creation of tourism development. Methods used for data collecting, processing and analysis are: historical, descriptive, comparative, case study, survey (SPSS version 20. Elements that need improving and further development are highlighted. The research results can help the tourist destination management, in this case TC, but also all segments of the tourism industry of TC, improve their offer and communication with a potential tourism market.

  15. Cycad mutualist offers more than pollen transport.

    Science.gov (United States)

    Marler, Thomas E

    2010-05-01

    Specialist insects share obligate mutualisms with some contemporary cycad species whereby the insect's pollination services are rewarded with a nursery in which the insect's larvae consume the postdispersal male cone. I prevented visits of the pollinator moth Anatrachyntis sp. to male Cycas micronesica (Cycadaceae) cones to show that consumption of the cone tissue by the mutualist hastened initiation of the plant's subsequent reproductive event. This is the first documented case where removal of a postdispersal cycad pollination organ speeds up subsequent reproductive events, and the current paradigm that the offering of cone tissue as a nursery is a sacrifice by the plant in return for the pollination services is therefore inaccurate. In C. micronesica, the herbivory stage of pollination mutualism confers a cryptic benefit of cone tissue disposal, which translates into an increase in ultimate lifetime reproductive effort. The plant population relies on the pollinator for moving gametes, as well as for increasing the number of male coning events. The dual benefits afforded to the plant by associating with this pollinator shows that mutualism can operate simultaneously on very different traits.

  17. What One Physicist Has to Offer

    Science.gov (United States)

    Ross, Marc

    2004-05-01

    I was a particle theorist. In the early 1970s I began to analyze energy and its use in society. My theme is: What can physicists offer on a societal issue like energy? I have four topics: 1) Traffic safety and vehicle mass. The measurements are the record of some 40,000 deaths per year, vehicle characterizations and registrations. The statistical record is good, but information is lacking on physical processes in serious crashes. Our insight: while driver behavior is critical to safety, so is vehicle quality and design. Although one cannot definitively separate the injury impacts associated with momentum transfer from those due to intrusion, mass as such is not critical to safety. 2) Prospects for improving the energy efficiency of industrial processes. Our "measurements" were planning documents and interviews enabling us to analyze which "energy projects" were undertaken and which not. Insight: capital for projects was not allocated according to textbook economics; instead it was rationed. 3) Energy use by cars. Based on dynamometer studies motivated by the 1990 Clean Air Act Amendments, we created models of energy consumption that enable evaluation of modifications such as adopting a small engine while supplementing its capability for power. Insight: Vehicles could be designed to use much less fuel; but the gain for society is offset by low interest by new-car-buyers and manufacturers. 4) The effectiveness of automotive emissions controls. In addition to laboratory studies, we had surveys in "non-attainment" areas. Insight: Controls installed by original manufacturers are more robust and effective than repairs. Of the four, this is the one success for society. Conclusions: There are fascinating and solvable analytical challenges everywhere you look. But applications are hampered by the lack of a heritage and the close coupling between theorists and experimenters we know in physics.

    To explore the abnormal intrinsic functional hubs in alcohol dependence using voxelwise degree centrality analysis approach, and their relationships with clinical features. Twenty-four male alcohol dependence subjects free of medicine (mean age, 50.21±9.62 years) and 24 age- and education-matched male healthy controls (mean age, 50.29±8.92 years) were recruited. The alcohol use disorders identification test and the severity of alcohol dependence questionnaire (SADQ) were administered to assess the severity of alcohol craving. Voxelwise degree centrality approach was used to assess the abnormal intrinsic functional hubs features in alcohol dependence. Simple linear regression analysis was performed to investigate the relationships between the clinical features and abnormal intrinsic functional hubs. Compared with healthy controls, alcohol dependence subjects exhibited significantly different degree centrality values in widespread left lateralization brain areas, including higher degree centrality values in the left precentral gyrus (BA 6), right hippocampus (BA 35, 36), and left orbitofrontal cortex (BA 11) and lower degree centrality values in the left cerebellum posterior lobe, bilateral secondary visual network (BA 18), and left precuneus (BA 7, 19). SADQ revealed a negative linear correlation with the degree centrality value in the left precentral gyrus (R(2)=0.296, P=0.006). The specific abnormal intrinsic functional hubs appear to be disrupted by alcohol intoxication, which implicates at least three principal neural systems: including cerebellar, executive control, and visual cortex, which may further affect the normal motor behavior such as an explicit type of impaired driving behavior. These findings expand our understanding of the functional characteristics of alcohol dependence and may provide a new insight into the understanding of the dysfunction and pathophysiology of alcohol dependence.

The teaching methodology used was developed over these 20 years into the classroom research. It is based on five practical activities carried out at the initial moment by the students themselves, who monitor the effects of different physical activity situations through the measurement of some plasma metabolites on point of care devices. After instructions the students perform the exercises collects and tabulate the data generated and document all the doubts arising. The educational goal right now is to show that the theory related to muscle contraction, the ATP-producing metabolic pathways is linked to their profession. At adequate moments each group presents to the whole class the practical activity carried out, the data and the doubts produced. After a fully discussion the students are able to relate the data to the studied theory. Also the initial doubts are clarified. A questionnaire applied before and after the discipline indicates the learning effectiveness of this method. Some other results: the students who have demonstrated special interest in the classroom normally join into de lab. Simultaneously they are also prepared for the teaching activity. The demand of specialization course is greater than the supply. The financial resources generated are expressive and administered by the University Foundation. They are fully applied to purchase permanent and consumption materials and for the payment of eventual scholarships for lab researchers. The publication in indexed journals has been constant and regular, and the obtained experimental results always return to the

    Carboranes are a class of carbon-containing polyhedral boron cluster compounds with globular geometry and hydrophobic surface that interact with hormone receptors such as estrogen receptor (ER) and androgen receptor (AR). We have synthesized BA321, a novel carborane compound, which binds to AR. We found here that it also binds to ERs, ERα and ERβ. In orchidectomized (ORX) mice, femoral bone mass was markedly reduced due to androgen deficiency and BA321 restored bone loss in the male, whilst the decreased weight of seminal vesicle in ORX mice was not recovered by administration of BA321. In female mice, BA321 acts as a pure estrogen agonist, and restored both the loss of bone mass and uterine atrophy due to estrogen deficiency in ovariectomized (OVX) mice. In bone tissues, the trabecular bone loss occurred in both ORX and OVX mice, and BA321 completely restored the trabecular bone loss in both sexes. Cortical bone loss occurred in ORX mice but not in OVX mice, and BA321 clearly restored cortical bone loss due to androgen deficiency in ORX mice. Therefore, BA321 is a novel selective androgen receptor modulator (SARM) that may offer a new therapy option for osteoporosis in the male. - Highlights: • A novel carborane compound BA321 binds to both AR and ERs, ERα and ERβ. • BA321 restores bone loss in orchidectomized mice without effects on sex organ. • BA321 acts as an estrogen agonist in bone and uterus in ovariectomized mice. • BA321 may be a new SARM to prevent the loss of musculoskeletal mass in elder men.

    Full Text Available Conservation and restoration of cultural heritage are the objects of great interest worldwide. For setting the correct methodology for the procedures of the restoration it is very important to have the right information about the state of the object and the characteristics of the original materials. The basis of our examinations were clay products (samples of bricks, terracotta and clay roof tile from the middle ages, the fortress in Bač. The following methods were used: x-ray diffraction, classic chemical analysis, SEM-EDS, Hg-porosimetry and dilatometry. Based on the used methods, mineral composition, temperature and regime of firing and textural properties of the examined materials were determined. The degree of destruction of examined materials was also identified, in order to find compatible materials for future techniques of conservation and restoration.

    Ceramic materials based on pure barium hafnate (BaHfO{sub 3}) have been obtained as a powder by the co-precipitation method. The powders obtained have a cubic structure that favors the thermoluminescent and optical properties, through which a better detection of the non-ionizing radiation is allowed. With these powders various tests were performed in the ultraviolet range at different exposure times. These thermoluminescent (Tl) studies were carried out using a Tl 3500 hand held reader which yielded a brightness curve that ranged from room temperature to the 350 degrees Celsius. This BaHfO{sub 3} response exhibits a broad brightness curve with a single peak centered around 225 degrees Celsius. Finally, is reported that there are materials of barium hafnate (BaHfO{sub 3}) doped with some rare earths (Eu, Tb) which, instead of improving the performance of the powders, decrease it, so that the use of intrinsic barium hafnate is the most appropriate.

  15. High spin properties of 124Ba

    2002-03-01

    The 124Ba nucleus is investigated on the basis of the method of statistical mechanics by assuming the nucleons to move in triaxially deformed Nilsson potential. The variation in the Fermi energies of protons and neutrons is studied as a function of spin and temperature. The Fermi energies determined as a function of angular momentum is used to study the dependence of shell correction on angular momentum using the Strutinsky smoothing procedure. The most important observation is that the shell correction is almost the same for all spins for 124Ba. The spin cutoff parameter and the single particle level density parameter are studied as a function of spin and temperature. Constant entropy lines drawn by plotting the excitation energy against angular momentum are found to be roughly at constant energy above the yrast line and are almost equally spaced. It is observed that no yrast traps are present for 124Ba.

  19. Quantitative modeling of degree-degree correlation in complex networks

    CERN Document Server

    Niño, Alfonso

    2013-01-01

    This paper presents an approach to the modeling of degree-degree correlation in complex networks. Thus, a simple function, \\Delta(k', k), describing specific degree-to- degree correlations is considered. The function is well suited to graphically depict assortative and disassortative variations within networks. To quantify degree correlation variations, the joint probability distribution between nodes with arbitrary degrees, P(k', k), is used. Introduction of the end-degree probability function as a basic variable allows using group theory to derive mathematical models for P(k', k). In this form, an expression, representing a family of seven models, is constructed with the needed normalization conditions. Applied to \\Delta(k', k), this expression predicts a nonuniform distribution of degree correlation in networks, organized in two assortative and two disassortative zones. This structure is actually observed in a set of four modeled, technological, social, and biological networks. A regression study performed...

  20. Crystallinity and stoichiometry of nano-structured sol-gel-derived BaTiO{sub 3} monolithic gels

    The crystallization behavior and stoichiometric changes of barium titanium alkoxide-derived monolithic gels prepared by the sol-gel process using a high-concentration Ba,Ti precursor solution (0.8 mol/L) were investigated during aging at room temperature. Crystallization of the gels (which were amorphous, per X-ray diffraction analysis immediately after gelation) into the BaTiO{sub 3} perovskite phase increased during aging and was associated with significant shrinkage of the gels. Crystallization reached a value of {approximately}82% by the final stage of shrinkage, assuming the degree of crystallization of a gel treated at 600 C to be 100%. The stoichiometry of the gels (Ba/Ti molar ratio) also changed considerably during aging, as estimated by the concentrations of Ba and Ti that remained in the expelled liquid resulting from syneresis at any time during the aging process. Deviation in the Ba/Ti ratio of the precursor solution ranged from 0.015 at the initial stage of shrinkage to 0.003 at the final stage, a value determined by inductively coupled plasma atomic emission spectroscopy. The present study demonstrates the great advantage of using high-concentration precursor solutions of barium titanium alkoxides, rather than low-concentration solutions, to obtain BaTiO{sub 3} gel monoliths with high density and crystallinity and little stoichiometric deviation, by sol-gel processing at room temperature.

    The liquidus temperatures of the BaO-BaCl2-MCl systems (with M = alkali metal) are determined by thermal analysis. The caloric effects observed during melting of the barium-containing chloride eutectic with barium oxide additions are studied. A chemical mechanism of barium oxide dissolution in the melts is confirmed. X-ray diffraction patterns taken for the melt solidified after experiment indicate the presence of barium oxychloride Ba4OCl6 in the solid phase. It is shown that the significant increase in the liquidus temperature in adding the barium oxide to barium-containing chloride molten mixtures is related to substantial changes in their composition and structure.

    Ba, the transmutation product of radioactive Cs, can be incorporated at levels of up to ∼0.07 formula units in Cs(1-2x)BaxAlSi2O6 aluminium pollucite formed by sol-gel methods and sintering at 1400 °C, with more Ba forming BaAl2Si2O8 phases. The effect of Ba substitution in pollucite-structured CsFeSi2O6 was also studied and no evidence of Ba substitution in the pollucite structure via cation vacancies or Fe2+ formation was obtained. The Ba entered a Fe-silicate glass structure. Charge compensation was also attempted with a Cs+ + Fe3+ ↔ Ba2+ + Ni2+ scheme but again the Ba formed a glass and NiO was evident. PCT leaching data showed CsFeSi2O6 to be very leach resistant.

    2014-07-14

    Mechanochemical milling provides a versatile method for the preparation of nano-sized, defect rich, polycrystalline materials. If ionic materials are considered, the transport parameters of the mobile ions may greatly differ from those of the microcrystalline counterparts prepared by conventional synthesis routes. Little is known about ionic conduction in nanocrystalline materials having crystal structures that offer spatially confined transport pathways. Here, we focused on mechanosynthesized BaMgF4 that combines both nanocrystallinity and anisotropic F(-) transport. The preparation of nanocrystalline BaMgF4 is presented as a facile and rapid one-pot procedure. The reaction was followed by X-ray diffraction and high-resolution (19)F nuclear magnetic resonance (NMR) spectroscopy. NMR helped prove the formation of X-ray amorphous compounds as well as the transformation of the starting materials into the final product BaMgF4. Most importantly, besides enhanced conduction properties compared to a single crystal, our broadband impedance spectra reveal characteristics pointing to anisotropic (low dimensional) ion transport processes even in the nanocrystalline form of BaMgF4.

    Magnetic excitations for Ba isotopes are discussed within the nucleon-pair shell model trmicated iti the SDsubspace. With the SD pair determined by a surface-δ interaction, M1 transitions for 1344Ba are well fitted. The M1 andM3 transitions for 132Ba and 130Ba are also predicted. It is shown that the statement, the collective magnetic propertiesarc due to the orbital motion of nucleons, is approximately valid.

    Progress on a method of barium tagging for the nEXO double beta decay experiment is reported. Absorption and emission spectra for deposits of barium atoms and ions in solid xenon matrices are presented. Excitation spectra for prominent emission lines, temperature dependence and bleaching of the fluorescence reveal the existence of different matrix sites. A regular series of sharp lines observed in Ba$^+$ deposits is identified with some type of barium hydride molecule. Lower limits for the fluorescence quantum efficiency of the principal Ba emission transition are reported. Under current conditions, an image of $\\le10^4$ Ba atoms can be obtained. Prospects for imaging single Ba atoms in solid xenon are discussed.

    Low-spin states in the neutron-rich, N = 90 nuclide $^{146}$Ba were populated following $\\beta$-decay of $^{146}$Cs, with the goal of clarifying the development of deformation in Ba isotopes through delineation of their non-yrast structures. Fission fragments of $^{146}$Cs were extracted from a 1.7-Ci $^{252}$Cf source and mass-selected using the CARIBU facility. Low-energy ions were deposited at the center of a box of thin $\\beta$ detectors, surrounded by a high-efficiency HPGe array. The new $^{146}$Ba decay scheme now contains 31 excited levels extending up to ~2.5 MeV excitation energy, double what was previously known. These data are compared to predictions from the Interacting Boson Approximation (IBA) model. It appears that the abrupt shape change found at N = 90 in Sm and Gd is much more gradual in Ba and Ce, due to an enhanced role of the $\\gamma$ degree of freedom.

    The Ba-construction is a basic syntactic pattern in modern Chinese, and it is often regarded as one of its characteristic grammatical phenomena. This thesis demonstrates the Ba-VP sentences in details and introduces some suggestive methods to translate the Ba-VP sentences. In English there is no equivalent Ba-VP sentence pattern, thus, when translating Chines Ba-VP sentences into English, we should translate them according to their semantic functions such as “disposition”, “topic/comment” and “causation”。

    The alkaline-earth fluorohalide crystals MFX, where M=Ca, Sr, Ba, Pb and X=Cl, Br, I, form an important class of materials crystallizing in the PbFCl-type tetragonal structure which is also called the matlockite structure. These compounds have long been of interest because of the various defect species which can be detected by spin resonance and associated techniques. The crystals were prepared by slow cooling of the melt of a stoichiometric mixture of BaF 2 and the corresponding chloride or bromide under 0.2 bar of ultrapure argon (5N5), often slightly fluorinated. We have studied the mechanoluminescence (ML) of BaFBr:Sm 2+ and BaFCl:Sm 2+ crystals. It is seen that after the impact of a moving piston, initially the ML intensity increases with time, attains a maximum value and then it decreases with time up to a particular minimum value, and then it increases again, attaining a peak value and finally disappears. The first peak lies in the deformation region and the second peak lies in the post-deformation region. The ML intensity of the BaFCl:Sm 2+ crystal is much higher than the ML intensity of the BaFBr:Sm 2+ crystal. For different impact velocities, the ML intensity increases with velocity; and the total ML intensity attains a saturation value for higher impact velocities. The total ML intensity increases with the increase in the applied load. It is suggested that the moving dislocation produced during deformation of crystals captures holes from hole-trapped centers (like H centers), and the subsequent radiative recombination of the dislocation holes with electron gives rise to ML. Thermoluminescence (TL) of BaFBr:Sm 2+ and BaFCl:Sm 2+ crystals was studied after exposure to ultraviolet rays with the help of a TLD reader. The peak of TL for the BaFBr:Sm 2+ crystal is found at ∼247°C and for BaFCl:Sm 2+ crystals at 283°C. The TL intensity initially increases with increase in the UV radiation and then it attains saturation for higher values of UV exposure. The

    Carboranes are a class of carbon-containing polyhedral boron cluster compounds with globular geometry and hydrophobic surface that interact with hormone receptors such as estrogen receptor (ER) and androgen receptor (AR). We have synthesized BA321, a novel carborane compound, which binds to AR. We found here that it also binds to ERs, ERα and ERβ. In orchidectomized (ORX) mice, femoral bone mass was markedly reduced due to androgen deficiency and BA321 restored bone loss in the male, whilst the decreased weight of seminal vesicle in ORX mice was not recovered by administration of BA321. In female mice, BA321 acts as a pure estrogen agonist, and restored both the loss of bone mass and uterine atrophy due to estrogen deficiency in ovariectomized (OVX) mice. In bone tissues, the trabecular bone loss occurred in both ORX and OVX mice, and BA321 completely restored the trabecular bone loss in both sexes. Cortical bone loss occurred in ORX mice but not in OVX mice, and BA321 clearly restored cortical bone loss due to androgen deficiency in ORX mice. Therefore, BA321 is a novel selective androgen receptor modulator (SARM) that may offer a new therapy option for osteoporosis in the male. Copyright © 2016 Elsevier Inc. All rights reserved.

    Whether a doctor, professional baseball manager, or a politician, having successful negotiation skills is a critical part of being a leader. Building upon prior journal articles on negotiation strategy, the author presents the concept of the multiple equivalent simultaneous offer (MESO). The concept of a MESO is straightforward: as opposed to making a single offer, make multiple offers with several variables. Each offer alters the different variables, such that the end result of each offer is equivalent from the perspective of the party making the offer. Research has found several advantages to the use of MESOs. For example, using MESOs, an offer was more likely to be accepted, and the counterparty was more likely to be satisfied with the negotiated deal. Additional benefits have been documented as well, underscoring why a prepared radiology business leader should understand the theory and practice of MESO.

    2014-12-01

    In 2007, the Department of Natural Resources and Environmental Science established the first undergraduate degree in Ecohydrology in the United States. The degree was designed to prepare students for careers as hydrologists while also including coursework equivalent to a minor in ecology (UNR does not officially offer a minor in ecology). The development of the major was intended to provide students with useful skills and training for the job market, and also to increase enrollment in the University's water-related undergraduate majors. The Department also established an Ecohydrology minor. Since the degree was established, average enrollment in the major has been almost two times higher than the previous Watershed Science option in Environmental Science (the closest comparable degree offering at UNR). The Department has graduated 19 students as of May 2014, and an additional 8 students have graduated with the Ecohydrology minor. Several Ecohydrology graduates have gone on to graduate degrees, and most of the remainder are employed in water-related areas. The students have established an Ecohydrology Club at UNR and are active in organizing water-related activities to do together. This presentation will describe the development of the degree, its implementation, and challenges and opportunities for carrying out an undergraduate degree in Ecohydrology. It will also discuss potential development of a 5-year Bachelor of Science-Master of Science (BS-MS) degree in Ecohydrology.

    Water-soluble BaYF5:Yb3+/Er3+ nanoparticles with the surface functionalized by a layer of poly(acrylic acid) (PAA) were synthesized via a facile one-step PAA-assisted hydrothermal method. Bovine serum albumin (BSA) protein was conjugated with BaYF5:Yb3+/Er3+ upconversion nanoparticles via free carboxylic acid groups on the surface of nanoparticles. The final products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), infrared (IR) spectrophotometry, ultraviolet (UV) spectrophotometry and photoluminescence spectroscopy (PL). The XRD results showed that PAA-capped BaYF5:Yb3+/Er3+ upconversion nanoparticles could be obtained via a PAA assisted hydrothermal process with the pH value of 8 at 200 degrees C for 24 h. The TEM results showed that the morphology of BaYF5:Yb3+/Er3+ nanoparticles was spherical particles with an average diameter of about 4 nm. The IR and UV spectra showed that BSA has been conjugated with BaYF5:Yb3+/Er3+ up-conversion nanoparticles. The luminescence properties of BaYF5:Yb3+/Er3+ up-conversion nanoparticles were also studied. The luminescence properties of the products suggest that BaYF5:Yb3+/Er3+ upconversion nanoparticles have promising applications for labels in biological assays.

    We present the first-time growth of bulk BaSnO3 single crystals from the melt by direct solidification, their basic electrical and optical properties as well as their structural quality. Our measurement of the melting point (MP) of BaSnO3 amounts to 1855 °C  ±  25 K. At this temperature an intensive decomposition and non-stoichiometric evaporation takes place as the partial pressure of SnO(g) is about 90 times higher than that of BaO(g). X ray powder diffraction identified only the BaSnO3 perovskite phase, while narrow rocking curves having a full width at half maximum of 26 arcsec and etch pit densities below 106 cm-2 confirm a high degree of structural perfection of the single crystals. In this respect they surpass the structural properties of those single crystals that were reported in the literature. The electrical conductivity of nominally undoped crystals depends on the growth conditions and ranges from insulating to medium n-type conductivity. After post-growth annealing in an oxidizing atmosphere undoped crystals are generally insulating. Doping the crystals with lanthanum during growth results in a high n-type conductivity. For a La doping concentration of 0.123 wt.% we measured an electron concentration of 3.3  ×  1019 cm-3 and an electron mobility of 219 cm2 V-1 s-1. Based on optical absorption measurements we determined an energy of 3.17  ±  0.04 eV at 5 K and of 2.99  ±  0.04 eV at 297 K for the indirect band gap of BaSnO3.

    Soluble sulfate ions in nuclear waste can have detrimental effects on cementitious wasteforms and disposal facilities based on Portland cement. As an alternative, Ba(OH){sub 2}–Na{sub 2}SO{sub 4}–blast furnace slag composites are studied for immobilisation of sulfate-bearing nuclear wastes. Calcium aluminosilicate hydrate (C–A–S–H) with some barium substitution is the main binder phase, with barium also present in the low solubility salts BaSO{sub 4} and BaCO{sub 3}, along with Ba-substituted calcium sulfoaluminate hydrates, and a hydrotalcite-type layered double hydroxide. This reaction product assemblage indicates that Ba(OH){sub 2} and Na{sub 2}SO{sub 4} act as alkaline activators and control the reaction of the slag in addition to forming insoluble BaSO{sub 4}, and this restricts sulfate availability for further reaction as long as sufficient Ba(OH){sub 2} is added. An increased content of Ba(OH){sub 2} promotes a higher degree of reaction, and the formation of a highly cross-linked C–A–S–H gel. These Ba(OH){sub 2}–Na{sub 2}SO{sub 4}–blast furnace slag composite binders could be effective in the immobilisation of sulfate-bearing nuclear wastes.

    Plastic deformation is a prominent factor in determining the lubricating value of solid lubricants. Little information is available and its direct measurement is difficult so hardness, which is an indirect measure of this property was determined for fluoride solid lubricant compositions. The Vickers hardness of BaF2 and CaF2 single crystals was measured up to 670 C in a vacuum. The orientation of the BaF2 was near the (013) plane and the CaF2 was about 16 degrees from the degrees from the (1'11) plane. The BaF2 has a hardness of 83 kg/sq mm at the 25 C and 9 at the 600 C. The CaF2 is 170 at 25 C and 13 at 670 C. The decrease in hardness in the temperature range of 25 to 100 C is very rapid and amounts to 40% for both materials. Melts of BaF2 and CaF2 were made in a platinum crucible in ambient air with compositions of 50 to 100 wt% BaF2. The Vickers hardness of these polycrystalline binary compositions at 25 C increased with increasing CaF2 reaching a maximum of 150 kn/sq mm near the eutectic. The polycrystalline CaF2 was 14% softer than that of the single crystal surface and BsF2 was 30% harder than the single crystal surface. It is estimated that the brittle to ductile transition temperature for CaF2 and BaF2 is less than 100 C for the conditions present in the hardness tester.

    Full Text Available It is critical to obtain a fine description of the topology of a complex network when modeling its behavior, as the network’s functionality heavily relies on its structure.  Capacity Restricted model evolved from BA model (CRBA for complex network proposed in this paper is the first attempt to date to take the node’s capacity distribution into modeling. CRBA is a universal and academic model, we learn it qualitatively and acquire several meaningful outcomes. Then we deduce a practical model from CRBA (CRBAC which has a constant node’s capacity distribution. We make a quantitative comparison of the properties of CRBAC with those of BA model, including the degree distribution, clustering coefficient and the average path length. Since majority of networks in practical are capacity–restricted, our model provides a better description of real-life complex networks.

    The BaBar experiment at the Stanford Linear Accelerator Center is designed to perform a search for CP violation by ana-lyzing the decays of a very large sample of B and B(Bar) mesons produced at the high luminosity PEP-II accelerator. The data acquisition system must cope with a sustained high event rate, while supporting real time feature extraction and data compression with minimal dead time. The BaBar data acquisition system is based around a common VME interface to the electronics read-out of the separate detec-tor subsystems. Data from the front end electronics is read into commercial VME processors via a custom "Personality Card" and PCI interface. The commercial CPUs run the Tornado operating system to provide a platform for detector subsystem code to perform the necessary data processing. The data is read out via a non-blocking network switch to a farm of commercial UNIX processors. The current implementation of the BaBar data acquisition sys-tem has been shown to sustain a Level 1 trigger rate of 1.3...

    1991-06-01

    A gas-slag-metal equilibration technique was used to determine the sulfide capacity of the BaO-BaF2 system at 1473 and 1573 K. The dependence of carbonate capacity on the slag composition was also measured at these temperatures. It was found that the BaO-BaF2 system has the highest sulfide capacities among the fluxes which are of metallurgical interest. The dependence of sulfide and carbonate capacities on the partial pressure of O2 and CO2 was also investigated. The partial pressure of CO2 proved to have a strong effect on these values at the investigated temperatures. The influence of temperature on the sulfide and carbonate capacities was studied in the temperature range between 1423 and 1623 K. The data for sulfide and carbonate capacities were correlated in order to check if the carbonate capacity can be used as a measure of basicity of slags. It was found that the carbonate capacity can be used as a representative measure of the slag basicity at low contents of BaO and at temperatures higher than 1623 K when the carbonate dissolution into the slag is low and the ratio of the activity coefficient of a sulfide ion to that of a carbonate ion is independent of slag composition.

    Full Text Available The maps of the form f( x = ∑ i=1 n a i ⋅x⋅ b i , called 1-degree maps, are introduced and investigated. For noncommutative algebras and modules over them 1-degree maps give an analogy of linear maps and differentials. Under some conditions on the algebra 𝒜 , contractibility of the group of 1-degree isomorphisms is proved for the module l 2 ( 𝒜 . It is shown that these conditions are fulfilled for the algebra of linear maps of a finite-dimensional linear space. The notion of 1-degree map gives a possibility to define a nonlinear Fredholm map of l 2 ( 𝒜 and a Fredholm manifold modelled by l 2 ( 𝒜 . 1-degree maps are also applied to some problems of Markov chains.

    To assess the prevalence and characteristics of curriculum in dual doctor of pharmacy (PharmD)/master of public health (MPH) degree programs offered by US pharmacy programs. An 18-item survey instrument was developed and distributed online to faculty members at US colleges and schools of pharmacy. Of the 110 colleges and schools that responded, 23 (21%) offered a PharmD/MPH degree. Common characteristics of these 23 programs included current PharmD program structure (3 + 1 year), early curricular recruitment, small enrollment, and interdisciplinary coursework occurring online and in the classroom. The impact of the dual degree on the curriculum and longevity of the dual-degree programs varied. About 55% of responding programs without a formal dual-degree program reported that additional public health training was available. Twenty-one percent of colleges and schools of pharmacy offer a combined PharmD/MPH dual degree. Most programs required an additional 1 or 2 semesters to complete both degrees.

    Frequently, it is argued that the microstates responsible for the Bekenstein-Hawking entropy should arise from some physical degrees of freedom located near or on the black hole horizon. In this essay, we elucidate that instead entropy may emerge from the conversion of physical degrees of freedom, attached to a generic boundary, into unobservable gauge degrees of freedom attached to the horizon. By constructing the reduced phase space, it can be demonstrated that such a transmutation indeed takes place for a large class of black holes, including Schwarzschild.

Thermal analysis results showed that glass transition temperature increased as BaO content increased because of the stabilizing effect of Ba{sup 2+} on the glass network. Additional analyses using bulk compression and ring deformation models revealed that the ratio between theoretical bulk modulus and experimental bulk modulus increased; this result indicated that the compression mechanism mainly involved isotropic ring compression. Furthermore, the increase in non-bridging oxygen formation with BaO addition caused a decrease in optical energy gap and an increase in refractive index. An increase in Urbach energy indicated that the degree of disorder in the glass system also increased.

    On the basis of the thermochemical and phase equilibrium experimental data, the phase diagram of the Ba - Mg binary system has been assessed by means of the calculation of phase diagrams technique. The liquid phase is of unlimited solubility and modeled as a solution phase using the Redlich-Kister equation. The intermetallic compounds, Mg{sub 17}Ba{sub 2}, Mg{sub 23}Ba{sub 6} and Mg{sub 2}Ba, with no solubility ranges are treated as strict stoichiometric compounds with the formula Mg{sub m} Ba{sub n}. Two terminal phases, BccBa and HcpMg, are kept as solution phases, since the solubilities of the two phases are of considerable importance. After optimization, a set of self-consistent thermodynamic parameters has been obtained. The calculated values agree well with the available experimental data.

  3. Perceived value creation process: focus on the company offer

    Directory of Open Access Journals (Sweden)

    Irena Pandža Bajs

    2012-12-01

    Full Text Available In the competitive business environment, as the number of rational consumers faced with many choices increases, companies can achieve their dominance best by applying the business concepts oriented to consumers in order to deliver a value which is different and better than that of their competitors. Among the various products on the market, an educated consumer chooses the offer that provides the greatest value for him/her. Therefore, it is essential for each company to determine how consumers perceive the value of its offer, and which factors determine the high level of perceived value for current and potential consumers. An analysis of these factors provides guidance on how to improve the existing offer and what the offer to be delivered in the future should be like. That could increase the perceived value of the company offer and result in a positive impact on consumer satisfaction and on establishing a stronger, longterm relationship with consumers. The process of defining the perceived value of a particular market offer is affected by the factors of the respective company’s offer as well as by competition factors, consumer factors and buying process factors. The aim of this paper is to analyze the relevant knowledge about the process of creating the perceived value of the company’s market offer and the factors that influence this process. The paper presents a conceptual model of the perceived value creation process in consumers’ mind.

  10. Negotiation as a form of persuasion: arguments in first offers.

    Maaravi, Yossi; Ganzach, Yoav; Pazy, Asya

    2011-08-01

    In this article we examined aspects of negotiation within a persuasion framework. Specifically, we investigated how the provision of arguments that justified the first offer in a negotiation affected the behavior of the parties, namely, how it influenced counteroffers and settlement prices. In a series of 4 experiments and 2 pilot studies, we demonstrated that when the generation of counterarguments was easy, negotiators who did not add arguments to their first offers achieved superior results compared with negotiators who used arguments to justify their first offer. We hypothesized and provided evidence that adding arguments to a first offer was likely to cause the responding party to search for counterarguments, and this, in turn, led him or her to present counteroffers that were further away from the first offer.

  11. Determination of Sr and Ba partition coefficients between apatite from fish ( Sparus aurata) and seawater: The influence of temperature

    Science.gov (United States)

    Balter, Vincent; Lécuyer, Christophe

    2010-06-01

    The Sr/Ca and Ba/Ca ratios in inorganic apatite are strongly dependent on the temperature of the aqueous medium during precipitation. If valid in biogenic apatite, these thermometers would offer the advantage of being more resistant to diagenesis than those calibrated on biogenic calcite and aragonite. We have reared seabreams ( Sparus aurata) in tanks with controlled conditions during experiments lasting for more than 2 years at 13, 17, 23 and 27 °C, in order to determine the variations in Sr and Ba partitioning relative to Ca ( DSr and DBa, respectively) between seawater and fish apatitic hard tissues (i.e. teeth and bones), as a function of temperature. The sensitivity of the Sr and Ba thermometers (i.e. ∂ DSr/∂ T and ∂ DBa/∂ T, respectively), are similar in bone ( ∂Db-wSr/∂ T = 0.0036 ± 0.0003 and ∂Db-wBa/∂ T = 0.0134 ± 0.0026, respectively) and enamel ( ∂De-wSr/∂ T = 0.0037 ± 0.0005 and ∂De-wBa/∂ T = 0.0107 ± 0.0026, respectively). The positive values of ∂ DSr/∂ T and ∂ DBa/∂ T in bone and enamel indicate that DSr and DBa increase with increasing temperature, a pattern opposite to that observed for inorganic apatite. This distinct thermodependent trace element partitioning between inorganic and organic apatite and water highlights the contradictory effects of the crystal-chemical and biological controls on the partitioning of Ca, Sr and Ba in vertebrate organisms. Taking into account the diet Sr/Ca and Ba/Ca values, it is shown that the bone Ba/Ca signature of fish can be explained by Ca-biopurification and inorganic apatite precipitation, whereas both of these processes fail to predict the bone Sr/Ca values. Therefore, the metabolism of Ca as a function of temperature still needs to be fully understood. However, the biogenic Sr thermometer is used to calculate an average seawater temperature of 30.6 °C using the Sr/Ca compositions of fossil shark teeth at the Cretaceous/Tertiary boundary, and a typical seawater Sr

    Municipal solid waste incineration bottom ash (MSWI-BA) glass serves as a matrix of assorted bottom ash (BA) compounds. Deterioration of the BA glass phases is quite important as they regulate the distribution of a series of toxic elements. This paper studied landfilled MSWI-BA samples from the mineralogical and geochemical viewpoint to understand the deterioration behavior of the BA glass phases as well as mechanisms involved. Bulk analysis by PXRD as well as micro-scale analysis by optical microscopy and SEM/EDX was conducted for such purposes. The results revealed that dissolution of the BA glass phases has resulted in a deterioration layer of 10(0)-10(2)μm thickness after years of disposal. This rapid weathering process is highly relevant to the specific glass characteristics and solution pH. The BA glass phases with more embedded compounds and cracks/fissures tend to be more vulnerable. Moreover, the generally alkaline pH in ash deposit favors a rapid disruption of the glass phase. The weathering products are mainly gel phases (including Al-Si gel, Ca-Al-Si gel, Fe-Al-Si gel etc.) with iron oxide/hydroxide as accessory products. Breakdown of the BA glass phases triggers chemical evolution of the embedded compounds. Based on all the findings above, a model is proposed to illustrate a general evolution trend for the landfilled MSWI-BA glass phases. Copyright © 2014 Elsevier B.V. All rights reserved.

    Ba, the transmutation product of radioactive Cs, can be incorporated at levels of up to ∼0.07 formula units in Cs{sub (1−2x)}Ba{sub x}AlSi{sub 2}O{sub 6} aluminium pollucite formed by sol-gel methods and sintering at 1400 °C, with more Ba forming BaAl{sub 2}Si{sub 2}O{sub 8} phases. The effect of Ba substitution in pollucite-structured CsFeSi{sub 2}O{sub 6} was also studied and no evidence of Ba substitution in the pollucite structure via cation vacancies or Fe{sup 2+} formation was obtained. The Ba entered a Fe-silicate glass structure. Charge compensation was also attempted with a Cs{sup +} + Fe{sup 3+} ↔ Ba{sup 2+} + Ni{sup 2+} scheme but again the Ba formed a glass and NiO was evident. PCT leaching data showed CsFeSi{sub 2}O{sub 6} to be very leach resistant. - Highlights: • Barium can be incorporated into aluminium pollucite. • Positron annihilation lifetime spectroscopy supports a charge vacancy mechanism of incorporation. • Iron pollucite does not appear to incorporate any barium with either vacancy or charge compensation mechanisms. • Leaching data suggest iron pollucite is very leach resistant.

    To investigate the possible X(5) character of 122Ba, suggested by the ground state band energy pattern, the lifetimes of the lowest yrast states of 122Ba have been measured, via the Recoil Distance Doppler-Shift method. The relevant levels have been populated by using the 108Cd(16O,2n)122Ba and the Sn(13C,3n)122Ba reactions. The B(E2) values deduced in the present work are compared to the predictions of the X(5) model and to calculations performed in the framework of the IBA-1 and IBA-2 models.

    The influence of SiO2, FeOx, Cr2O3, BaCl2, CaO, and MgO on the sulfide capacity of the BaO-BaF2 system was measured at 1473 K, using a gas-slag-metal equilibration technique. It was found that the substitution of BaF2 by SiO2, FeOx, Cr2O3, and BaCl2 decreases the sulfide capacity of the BaO-BaF2 system. Similar results were obtained for the carbonate capacity. The CaO-saturated BaO-BaF2 flux, however, was found to have slightly higher sulfide and carbonate capacities than the pure BaO-BaF2 flux. The solubility of CaO increased with increasing BaF2 content and was 18 mol pet in BaF2 at 1473 K. The solubility of MgO in the BaO-BaF2 system at the same temperature is very low, and it has no effect on the sulfide and carbonate capacities. The solubility of BaS in the BaO-BaF2 system was also measured at 1473 K and had its maximum for the slag containing 40 mass pet BaO. The activity of BaO in the system was calculated from those data.

    Multiferroics can offer the possibility to manipulate the cross coupled order parameters by conjugate electric and magnetic fields. Switching off ferromagnetic order by an electric field for instance promises significant impact in the design of novel spintronic devices. Here we report on the reversible control of magnetism for a Fe thin film in proximity of a BaTiO3 single-crystal. Large magnetization changes emerge in response to ferroelectric switching and structural transitions of BaTiO3 controlled by applied electric fields and temperature, respectively.^ Interface strain coupling is the primary mechanism altering the induced magnetic anisotropy. As a result, coercivity changes up to 120% occur between the various structural states of BaTiO3. Up to 20% coercivity change is achieved via electrical control at room temperature. Our all solid state ferroelectric-ferromagnetic heterostructures open viable possibilities for new technological applications. ^S. Sahoo, S. Polisetty, C.-G. Duan, S. S. Jaswal, E. Y.

    We propose a generalization of the concept of assortativity based on the tensorial representation of multilayer networks, covering the definitions given in terms of Pearson and Spearman coefficients. Our approach can also be applied to weighted networks and provides information about correlations considering pairs of layers. By analyzing the multilayer representation of the airport transportation network, we show that contrasting results are obtained when the layers are analyzed independently or as an interconnected system. Finally, we study the impact of the level of assortativity and heterogeneity between layers on the spreading of diseases. Our results highlight the need of studying degree-degree correlations on multilayer systems, instead of on aggregated networks.

    The barium peroxide-based redox cycle was proposed in the late 1970s as a thermochemical energy storage system. Since then, very little attention has been paid to such redox couples. In this paper, we have revisited the use of reduction-oxidation reactions of the BaO2/BaO system for thermochemical heat storage at high temperatures. Using thermogravimetric analysis, reduction and oxidation reactions were studied in order to find the main limitations associated with each process. Furthermore, the system was evaluated through several charge-discharge stages in order to analyse its possible degradation after repeated cycling. Through differential scanning calorimetry the heat stored and released were also determined. Oxidation reaction, which was found to be slower than reduction, was studied in more detail using isothermal tests. It was observed that the rate-controlling step of BaO oxidation follows zero-order kinetics, although at high temperatures a deviation from Arrhenius behaviour was observed probably due to hindrances to anionic oxygen diffusion caused by the formation of an external layer of BaO2. This redox couple was able to withstand several redox cycles without deactivation, showing reaction conversions close to 100% provided that impurities are previously eliminated through thermal pre-treatment, demonstrating the feasibility of this system for solar thermochemical heat storage.

  4. A computer simulation study of oxygen defect centers in BaFBr and BaFCl

    Atomistic simulation techniques are used to examine several oxygen trapped-hole centers resulting from X-irradiation of BaFBr and BaFCl crystals. The calculations employ recently derived interatomic potentials for the oxide ion-host anion interactions. Particular attention is focussed on the sites occupied by the oxide impurity and the energetics of ionization. Our results show the defect model involving O{sup -} substitutional at a Br{sup -}/Cl{sup -} site to be a favorable trapped-hole center, in accord with the assignment proposed from electron paramagnetic resonance measurements. The defect simulations find a large energy barrier to oxide interstitial formation from the oxide precursor at a substitutional site, which suggests that conversion from O{sub x}{sup -} to O{sub int}{sup -} is highly unlikely as has been demonstrated in EPR experiments. Ion displacements following lattice relaxation about the defect are also examined. The position of O{sup -} substituted for Br{sup -} in BaFBr is computed to be displaced from the regular lattice site by 0.53 A, along the c axis towards the Ba{sup 2+} ion plane, in agreement with models derived later from ENDOR experiments, while O{sup -} substituted for F{sup -} remains on the lattice site in agreement with experiment.

    In this work, nanostructured samples of barium zirconate (BaZrO{sub 3}) and calcium zirconate (CaZrO{sub 3}) were synthesized by the gel-combustion method, using glycine as fuel. The ceramic powders were calcined at 550 Degree-Sign C for 2 h and subsequently heat treated at 1350 Degree-Sign C for 10 min (fast-firing). The X-ray diffraction technique was employed to identify and characterize the crystalline phases present in the synthesized powders, using the Rietveld method. Monophasic nanostructured samples of BaZrO{sub 3} and CaZrO{sub 3} presenting average crystallite sizes of around 8.5 and 10.3 nm, respectively, were found after fast-firing. (author)

  6. Sulfation and Desulfation Behavior of Pt-BaO/MgO-Al2O3 NOx Storage Reduction Catalyst.

    The comparative study between Pt-BaO/Al2O3 and Pt-BaO/MgO-Al2O3 gives the information about the effect of MgO addition to Al2O3 support on the sulfation and desulfation behavior of Pt-BaO/MgO-Al2O3 NOx storage reduction catalyst. The sulfated two samples were analyzed by using element analysis (EA), X-ray diffraction (XRD), H2 temperature programmed reaction (H2 TPRX) and NOx uptake measurement. The amount of sulfur uptake on 2 wt% Pt-20 wt% BaO/Al2O3 and 2 wt% Pt-20 wt% BaO/MgO-Al2O3 are almost identical as 0.45 and 0.40 of S/Ba, respectively, which yields the drastic decrease in NOx uptake for both sulfated samples. However, after desulfa- tion with H2 at 600 degrees C, the residual sulfur amount on MgO-Al2O3 supported catalyst is three times larger than that on Al2O3 supported one, indicating that sulfur species formed on the former are more stable than those on the latter. It is also well corresponding to the H2 TPRX results where the main H2S peak from MgO-Al2O3 supported sample is observed at higher temperature than Al2O3 supported one, resulting in the lower NOx uptake activity of former sample than the latter one. Meanwhile, after desulfation of MgO-Al2O3 supported sample at 700 degrees C and 800 degrees C, the activity is recovered more significantly due to the removal of the large amount of sulfur while Al2O3 supported one decreases monotonically due to the sintering of Pt crystallite and the formation of BaAl2O4 phase. It is summarized that MgO-Al2O3 supported catalyst enhances the thermal stability of the catalyst, however, forms the stable sulfate species, which needs to be improved to develop the more sulfur resistant NSR catalyst system.

    Organ offers in liver transplantation are high-risk medical decisions with a low certainty of whether a better liver offer will come along before death. We hypothesized that decision support could improve the decision to accept or decline. With data from the Scientific Registry of Transplant Recipients, survival models were constructed for 42,857 waiting-list patients and 28,653 posttransplant patients from 2002 to 2008. Daily covariate-adjusted survival probabilities from these 2 models were combined into a 5-year area under the curve to create an individualized prediction of whether an organ offer should be accepted for a given patient. Among 650,832 organ offers from 2008 to 2013, patient survival was compared by whether the clinical decision was concordant or discordant with model predictions. The acceptance benefit (AB)--the predicted gain or loss of life by accepting a given organ versus waiting for the next organ--ranged from 3 to -22 years (harm) and varied geographically; for example, the average benefit of accepting a donation after cardiac death organ ranged from 0.47 to -0.71 years by donation service area. Among organ offers, even when AB was >1 year, the offer was only accepted 10% of the time. Patient survival from the time of the organ offer was better if the model recommendations and the clinical decision were concordant: for offers with AB > 0, the 3-year survival was 80% if the offer was accepted and 66% if it was declined (P decision support may improve patient survival in liver transplantation. © 2015 American Association for the Study of Liver Diseases.

  8. Steam Electrolysis by Proton-Conducting Solid Oxide Electrolysis Cells (SOECs) with Chemically Stable BaZrO3-Based Electrolytes

    BaZrO3-based material was applied as the electrolyte for proton-conducting solid oxide fuel cells (SOECs). Compared with the instability of BaCeO3-based proton-conductors, BaZrO3-based material could be a more promising candidate for proton-conducting SOECs due to its excellent chemical stability under H2O conditions, but few reports on this aspect has been made due to the processing difficulty for BaZrO3. Our recent pioneering work has demonstrated the feasibility of using BaZrO3-based electrolyte for SOECs and the fabricated cell achieves relatively high cell performance, which is comparable or even higher than that for BaCeO3-based SOECs and offers better chemical stability. Cell performance can be further improved by tailoring the electrolyte and electrode. © The Electrochemical Society.

    We have recently begun a program of high precision measurements of the key production and destruction reactions of important radiochemical diagnostic isotopes, including several isotopes of uranium, plutonium and americium. The detector for advanced neutron capture experiments (DANCE), a 4π BaF2 array located at the Los Alamos Neutron Science Center, will be used to measure the neutron capture cross sections for most of the isotopes of interest. However, neutron capture measurements on many of the actinides are complicated by the presence of prompt γ-rays arising from low energy neutron-induced fission, which competes with neutron capture to varying degrees. Previous measurements of 235U using the DANCE array have shown that we can partially resolve capture from fission events based on total γ-ray calorimetry (i.e. total γ-ray energy versus γ-ray multiplicity). The addition of a dedicated fission-tagging detector to the DANCE array has greatly improved our ability to separate these two competing processes. In addition to higher quality neutron capture data, the addition of a fission-tagging detector offers a means to determine the capture-to-fission ratio (σγ/σf) in a single measurement, which should reduce the effect of systematic uncertainties. We are currently using a dual parallel-plate avalanche counter (PPAC) with the target material electro-deposited directly on the center cathode foil. This design provides a high efficiency for detecting fission fragments and allows loading of pre-assembled target/detector assemblies into the neutron beam line at DANCE. Results from tests of the fission-tag detector, as well as preliminary results from measurements on 235U and 252Cf that utilized the fission-tag detector will be presented.

  10. Co2FeAl based magnetic tunnel junctions with BaO and MgO/BaO barriers

    Full Text Available We succeed to integrate BaO as a tunneling barrier into Co2FeAl based magnetic tunnel junctions (MTJs. By means of Auger electron spectroscopy it could be proven that the applied annealing temperatures during BaO deposition and afterwards do not cause any diffusion of Ba neither into the lower Heusler compound lead nor into the upper Fe counter electrode. Nevertheless, a negative tunnel magnetoresistance (TMR ratio of -10% is found for Co2FeAl (24 nm / BaO (5 nm / Fe (7 nm MTJs, which can be attributed to the preparation procedure and can be explained by the formation of Co- and Fe-oxides at the interfaces between the Heusler and the crystalline BaO barrier by comparing with theory. Although an amorphous structure of the BaO barrier seems to be confirmed by high-resolution transmission electron microscopy (TEM, it cannot entirely be ruled out that this is an artifact of TEM sample preparation due to the sensitivity of BaO to moisture. By replacing the BaO tunneling barrier with an MgO/BaO double layer barrier, the electric stability could effectively be increased by a factor of five. The resulting TMR effect is found to be about +20% at room temperature, although a fully antiparallel state has not been realized.

  11. Annealing to reduce scattering centers in Czochralski-grown beta-BaB2O4.

    1999-02-20

    When a visible laser beam passes through beta-BaB(2)O(4) (BBO), scattered light can be observed along the beam within the crystal. Scattering centers caused by structural defects in Czochralski-grown BBO can be reduced by 95% by annealing at 920 degrees C. In the flux-grown BBO, centers actually increase by the same annealing because the process causes microcracks and/or secondary inclusions. It is shown that annealed Czochralski-grown BBO is superior to flux-grown BBO (annealed or as-grown) in terms of optical loss.

    Lead was doped in barium hexaferrite by co-precipitation method and the Pb-doped Ba-hexaferrite with compositions of Ba{sub 1-x}Pb{sub x}Fe{sub 12}O{sub 19} was investigated for the first time at x=0.0, 0.2, 0.4, 0.6, 0.8, 1.0. The molar ratio (Fe{sup 3+}/Ba{sup 2+}) of the solutions was kept 12 while pH was maintained at 13 by using NaOH (M=5) as precipitating agent. Prepared samples were sintered at 965{+-}5 Degree-Sign C for three hours. Structural and morphological studies were done by X-ray diffractometer (XRD) and the scanning electron microscope (SEM). SEM micrographs confirmed the formation of hexagonal plate like structures and particle size was observed to be increased with the increase in Pb concentration. The hysteresis loops obtained from the magnetometer showed that with the increase in Pb concentration, the coercivity decreased while magnetic induction and remanence increased, which in turn increased the maximum energy product (BH){sub max}. Lower coercivity and the moderate increase in saturation magnetization obtained from Pb doping makes the material useful for magnetic recording media and other frequency based applications.

    Spectral and kinetic properties of extrinsic crossluminescence (CL) in SrF{sub 2}:Ba (1%) and CaF{sub 2}:Ba (1%) are compared with those of intrinsic CL in BaF{sub 2} and are analyzed taking into account EXAFS data obtained at the Ba L{sub III} edge and results of first-principles calculations. The CL decay time was revealed to be longer in SrF{sub 2}:Ba and CaF{sub 2}:Ba compared to BaF{sub 2}. This fact contradicts the expected acceleration of luminescence decay which could result from an increased overlap of wave functions in solid solutions due to shortening of the Ba-F distance obtained in both EXAFS measurements and first-principles calculations. This discrepancy is explained by the effect of migration and subsequent non-radiative decay of the Ba (5p) core holes in BaF{sub 2} and by decreasing of the probability of optical transitions between Ba (5p) states and the valence band in SrF{sub 2}:Ba and CaF{sub 2}:Ba predicted by first-principles calculations. - Highlights: • The crossluminescence kinetics in SrF{sub 2}:Ba and CaF{sub 2}:Ba is slower than in BaF{sub 2}. • Ba{sup 2+} ions substitute for host Ca{sup 2+}(Sr{sup 2+}) ions in the on-center positions. • The nearest Ba-F distances in SrF{sub 2}:Ba and CaF{sub 2}:Ba are shorter than in BaF{sub 2}. • EXAFS data and first-principles calculations of the local structure agree well. • First-principles calculations explain slower luminescence decay in solid solutions.

    2005-01-01

    Luminous BA-SGs allow topics ranging from NLTE physics and the evolution of massive stars to the chemical evolution of galaxies and cosmology to be addressed. A hybrid NLTE technique for the quantitative spectroscopy of BA-SGs is discussed. Thorough tests and first applications of the spectrum synthesis method are presented for four bright Galactic objects. Stellar parameters are derived from spectroscopic indicators. The internal accuracy of the method allows the 1sigma-uncertainties to be reduced to <1-2% in Teff and to 0.05-0.10dex in log g. Elemental abundances are determined for over 20 chemical species, with many of the astrophysically most interesting in NLTE. The NLTE computations reduce random errors and remove systematic trends in the analysis. Inappropriate LTE analyses tend to systematically underestimate iron group abundances and overestimate the light and alpha-process element abundances by up to factors of 2-3 on the mean. Contrary to common assumptions, significant NLTE abundance correction...

    A spin-orbital quantum liquid state is theoretically proposed in the honeycomb lattice of Ba3CuSb2O9 , enabled by dynamic short-range correlations between the spin and orbital degrees of freedom. Using neutron diffraction, the local atomic structure of Ba3Cu1 +xSb2 -xO9 at x =0 and 0.1 is obtained via the pair density function analysis. The results indicate that both compositions exhibit local Jahn-Teller (JT) distortions with the elongated CuO3 octahedral configuration. In Ba3Cu1.1Sb1.9O9 , JT ordering of the distorted CuO3 octahedra gives rise to the orthorhombic symmetry with ferro-orbital order. On the other hand, in Ba3CuSb2O9 , even though the CuO3 octahedra are JT distorted, there is no long-range ordering hence the symmetry is hexagonal. Furthermore, the local singlet excitation at 5.8 meV observed in Ba3CuSb2O9 below 50 K is absent in Ba3Cu1.1Sb1.9O9 . Instead, an excitation at 2.5 meV is observed in the latter, which is likely associated with short-range spin order.

    Full Text Available Primary goal of the contemporary companies imposes monitoring of customer needs and appropriate responses to them, in order to achieve a significant competitive advantage in terms of profit growth and increased market share. In this sense, it can be concluded that the adaptation of supply accordingly to consumer needs presents a very significant component of increased competitiveness and overall business performance. This is achieved through adjustment of offered goods, by taking care of the consumers' needs and the efficient circulation of information from local vendors who are in direct contact with customers and senior decision making management levels. In this paper, authors analyze offer adjustment to the local market on the example of TEDDY S.p.A., at Serbian market, identify importance and role of project management in defining what the organization offers, and analyze project management of offer adjustment. Through selected case study, example of process of defining new company offer in accordance with the characteristics of the local market is presented as well as its impact on profitability growth. Furthermore, the role of offer adjustment in creating the market position of the organization is presented as well as the necessity of implementing such a project in time of expressed differences in the needs of consumers in different local markets.

    This study assesses the availability of websites offering to sell psilocybin spores and psilocybin, a powerful hallucinogen contained in Psilocybe mushrooms. Over a 25-month period beginning in March 2003, eight searches were conducted in Google using the term "psilocybin spores." In each search the first 100 nonsponsored links obtained were scored by two independent raters according to standardized criteria to determine whether they offered to sell psilocybin or psilocybin spores. No attempts were made to procure the products offered for sale in order to ascertain whether the marketed psilocybin was in fact "genuine" or "counterfeit." Of the 800 links examined, 58% led to websites offering to sell psilocybin spores. Additionally, evidence that whole Psilocybe mushrooms are offered for sale online was obtained. Psilocybin and psilocybin spores were found to be widely available for sale over the Internet. Online purchase of psilocybin may facilitate illicit use of this potent psychoactive substance. Additional studies are needed to assess whether websites offering to sell psilocybin and psilocybin spores actually deliver their products as advertised.

    It is possible to substitute Bi in the superconducting BaPb 0.75Bi 0.25O 3 by Sb or Te without destroying the superconductivity. With Sb, a continuous series of solid solutions BaPb 0.75Bi 0.25-ySb yO 3 (0 ⩽ y ⩽ 0.25) exists, while with Te, perovskite BaPb 0.75Bi 0.25-yTe yO 3 exists only upto y = 0.15. With increasing substitution by Sb or Te, T c decreases continously in both the systems. Superconductivity with a maximum T c of 8K is found in Ba 0.9La 0.1Pb 0.9-yBi yTl 0.1O 3 for y = 0.25.

    Based on the facts that the potential energy curves of the homo-nuclear group 2 dimers (group IIA metal), except Be2, are conformal, and they can be described by the Tang-Toennies potential model, a set of simple combining rules are proposed for the parameters of the reduced potentials of the hetero-nuclear dimers. Together with the well-established combining rules of the range parameters of the exponential repulsion and the known dispersion coefficients, these rules enable us to determine the ground state potential energy curves of MgCa, MgSr, MgBa, CaSr, CaBa, and SrBa from those of Mg2, Ca2, Sr2, and Ba2. The determined potentials are comparable to some ab initio calculations and in excellent agreement with the experiment.

    Ferroelectric-germanium heterostructures have a strong potential for multifunctional devices. Germanium (Ge) is attractive due to its higher electron and hole mobilities while ferroelectric BaTiO3 is promising due to its high relative permittivity, which can make next-generation low-voltage and low-leakage metal-oxide semiconductor field-effect transistors. Here, we investigate the growth, structural, chemical, and band alignment properties of pulsed laser deposited BaTiO3 on epitaxial (100)Ge, (110)Ge, and (111)Ge layers. Cross-sectional transmission electron microscopy micrographs show the amorphous nature of the BaTiO3 layer and also show a sharp heterointerface between BaTiO3 and Ge. The appearance of strong Pendellösung oscillation fringes from high-resolution X-ray diffraction implies the presence of parallel and sharp heterointerfaces. The valence band offset relation of ΔEV(100) ≥ ΔEV(111) > ΔEV(110) and the conduction band offset relation of ΔE(C)(110) > ΔE(C)(111) ≥ ΔE(C)(100) on crystallographically oriented Ge offer significant advancement for designing new-generation ferroelectric-germanium-based multifunctional devices.

  19. Synthesis strategies for improving the performance of doped-BaZrO 3 materials in solid oxide fuel cell applications

    KAUST Repository

    Bi, Lei

    2013-08-07

    Solid oxide fuel cells (SOFCs) offer an efficient energy conversion technology for alleviating current energy problems. High temperature proton-conducting (HTPC) oxides are promising electrolytes for this technology, since their activation energy is lower than that of conventional oxygen-ion conductors, enabling the operating temperature reduction at 600 °C. Among HTPC oxides, doped BaZrO3 materials possess high chemical stability, needed for practical applications. Though, poor sinterability and the resulting large volume of highly resistive grain boundaries hindered their deployment for many years. Nonetheless, the recently demonstrated high proton conductivity of the bulk revived the attention on doped BaZrO3, stimulating research on solving the sintering issues. The proper selection of dopants and sintering aids was demonstrated to be successful for improving the BaZrO3 electrolyte sinterability. We here briefly review the synthesis strategies proposed for preparing BaZrO3-based nanostructured powders for electrolyte and electrodes, with the aim to improve the SOFC performance. © Materials Research Society 2013.

    Belluzzi, Luca; Degl'Innocenti, Egidio Landi

    2007-01-01

    The physical interpretation of the spectral line polarization produced by the joint action of the Hanle and Zeeman effects offers a unique opportunity to obtain empirical information about hidden aspects of solar and stellar magnetism. To this end, it is important to achieve a complete understanding of the sensitivity of the emergent spectral line polarization to the presence of a magnetic field. Here we present a detailed theoretical investigation on the role of resonance scattering and magnetic fields on the polarization signals of the Ba II D1 and D2 lines of the Fraunhofer spectrum, respectively at 4934 \\AA\\ and 4554 \\AA. We adopt a three-level model of Ba II, and we take into account the hyperfine structure that is shown by the $^{135}$Ba and $^{137}$Ba isotopes. Despite of their relatively small abundance (18%), the contribution coming from these two isotopes is indeed fundamental for the interpretation of the polarization signals observed in these lines. We consider an optically thin slab model, throug...

  1. Are UK undergraduate Forensic Science degrees fit for purpose?

    Science.gov (United States)

    Welsh, Charles; Hannis, Marc

    2011-09-01

    In October 2009 Skills for Justice published the social research paper 'Fit for purpose?: Research into the provision of Forensic Science degree programmes in UK Higher Education Institutions.' The research engaged employers representing 95% of UK Forensic Science providers and 79% of UK universities offering Forensic Science or Crime Scene degree programmes. In addition to this, the research collected the views of 430 students studying these degrees. In 2008 there were approximately 9000 people working in the Forensic Science sector in the UK. The research found that the numbers of students studying Forensic Science or Crime Scene degrees in the UK have more than doubled since 2002-03, from 2191 in to 5664 in 2007-08. Over the same period there were twice as many females as males studying for these degrees. The research concluded that Forensic Science degree programmes offered by UK universities were of a good quality and they provided the student with a positive learning experience but the content was not relevant for Forensic Science employers. This echoed similar research by the former Government Department for Innovation, Universities and Skills on graduates from wider science, technology, engineering and mathematics degree programmes. The research also found that 75% of students studying Forensic Science or Crime Scene degrees expected to have a career in the Forensic Science sector, meaning that ensuring these courses are relevant for employers is a key challenge for universities. This paper reflects on the original research and discusses the implications in light of recent government policy. Copyright © 2011 Forensic Science Society. Published by Elsevier Ireland Ltd.

    Full Text Available The following paper aims to assess investor reaction to mandatory offers on the Warsaw Stock Exchange, which is important because knowledge about these reactions can be used to make better investment decisions. This paper highlights the importance of procedure in making a mandatory offer and its grounds in the Polish legal system. Additionally, it presents empirical research on the reactions of investors to mandatory offers on the Warsaw Stock Exchange. It has been provided that mandatory offers have a significant impact on the price of a company’s shares listed on the Warsaw Stock Exchange. Knowledge about the reactions of investors to a mandatory offer may be used when selecting securities for an investment portfolio. The findings may provide guidance in deciding whether to begin or end investment in the company, both for individual and institutional investors. The event study methodology approach used in the paper is regarded as valuable and can be the basis for further research in other areas of the capital market research, especially in the context of information efficiency.

    Graphical abstract: Transmission electron microscope images for the BaFe12O19. - Highlights: • BaFe{sub 12}O{sub 19}nanoparticles were prepared in single-phase from organometallic precursors. • BaFe{sub 12}O{sub 19} possesses small size 65 nm, H{sub C} = 3695 Oe and M{sub s} = 58 emu/g. • This method of preparation could be extended in the synthesis of other metal oxide nanoparticles. - Abstract: In this piece of work, high quality and homogeneity, barium hexaferrite (BaM) BaFe{sub 12}O{sub 19} nanoparticles were prepared from organometallic precursors for the 1st time. This method is based on the formation of supramolecular crystal structure of Ba[Fe(H{sub 3}NCH{sub 2}CH{sub 2}NH{sub 3})]Cl{sub 7}·8H{sub 2}O. The crystal structure, morphology and magnetic properties of BaFe{sub 12}O{sub 19} at two different annealing temperatures namely 1000 °C and 1200 °C were investigated using X-ray diffraction, transmission electron microscope TEM and vibrating sample magnetometry (VSM). The results show that monophasic nanoparticles of hexaferrites were obtained. Nanoparticles of crystallite size 40–50 nm distinguished by narrow distribution and excellent homogeneity were obtained with superior magnetic properties which suggested single-domain particles of Ba-M hexaferrite.

    Thams, Meg; Glueck, Deborah

    2007-04-01

    The purpose of this study was to determine if a gap exists in the skill and knowledge businesses require of marketing employees and what the Association to Advance Collegiate Schools of Business (AACSB) accredited schools actually provide. In this quantitative study, two set of data were collected and compared, and a gap analysis conducted. A questionnaire was used to obtain data from members of the Business Marketing Association (BMA) regarding course preferences that would best prepare students for positions in marketing. Records analysis was then undertaken of the marketing course offerings of AACSB accredited MBA programs offering an emphasis in Marketing. Gap analysis was conducted by applying a test of difference to the results of the two data collection efforts. Results of the study suggest that some misalignment between school offerings and business needs exists.

    Yin, Wenlong; Iyer, Abishek K.; Li, Chao; Yao, Jiyong; Mar, Arthur

    2017-09-01

    The ternary selenide Ba12In4Se20 was synthesized by reaction of BaSe, In2Se3, and Se at 1023 K. Single-crystal X-ray diffraction revealed a trigonal structure (space group R 3 bar, Z = 6, a = 10.0360(6) Å, c = 78.286(4) Å at room temperature) consisting of one-dimensional stacks of InSe4 tetrahedra, In2Se7 double tetrahedra, selenide Se2- anions, and diselenide Se22- anions, with Ba2+ cations in the intervening spaces. The selenide Ba12In4Se20 can be derived from the corresponding sulfide Ba12In4S19 by replacing one monoatomic Ch2- anion with a diatomic Ch22- anion. An optical band gap of 1.70(2) eV, consistent with the dark red colour of the crystals, was deduced from the UV-vis-NIR diffuse reflectance spectrum.

My favorite color is to add a little white on the whiteness, as if there was a snow-white eagle landing on a snow-covered mountain rock. My favorite color is to add a bit green on the greenness, as if there was an emerald parrot flying in the wild walnut woods. Deqin xianzi lyrics. These lyrics evoke a space beyond a sense of realism. In his book, Tales of Kha ba dkar po (ToK, Guo mentions these lines three times, suggesting a transcendental experience one may encounter in Tibetan areas while, at the same time, humbled by the mindset of human nature relations enacted by Tibetan people. ToK is, in many ways, a valuable academic work. Guo's favorite lines of xianzi allude to a 'space-in-between' the secular and sacred, which provides a unique experience for a broad readership, and induces the readers to deeper reflections on topics such as 'nature/ culture', 'belief', 'rite', and 'life/ death'. ToK is one of nineteen contemporary anthropological and ethnological works conducted in Yunnan Province, Southwest China and published in the 'Anthropology and Ethnology series in Contemporary China'. In the preface for the series, Yin (2012 suggests that there are two primary reasons for the somewhat slow development of Chinese scholarship in the field of anthropology and ethnology. One is the historically Han-centered intellectual atmosphere, and the other is the ideological ambivalence that ethnic culture has faced since the establishment of the People's Republic of China. In this context, Guo's longitudinal academic and intellectual engagement with the Tibetan communities in northwest Yunnan is included in this series as part of the increasing recognition of the significance of understanding southwest China's complex ethnic and cultural diversity.

    Full Text Available The epidemiological data on snakebites in the state of Paraíba, Brazil, is scarce. This accounts for the difficulties in helping the victims. Hence, to obtain the clinical and epidemic profile of the snakebite accidents in Paraíba, we studied the number of cases recorded in this state between January 1995 and December 2000. The data was collected from these sources: Center for Toxicological Assistance (Centro de Assistência Toxicológica - CEATOX and State Secretariat of Health (Secretaria Estadual de Saude, João Pessoa; 3rd Regional Health Center (3º Núcleo Regional de Saúde - NRS and the Division of Epidemiological Vigilance of the Municipal Secretariat of Health (Divisão de Vigilância Epidemiológica da Secretaria Municipal de Saúde - DVE/SMS, Campina Grande. The annual distribution of the snakebite incidence showed an irregularity and an increase in March, May and August; followed by a large reduction in November and December. It was also observed that snakebites occurred more frequently in the rural area, mainly among the male laborers between 10-49 years. In most cases, the bite occurred on the leg or foot. The interval between the snakebite and the medical assistance was less than six hours. The most common symptoms were pain, edema, erythema, and bleeding. The low lethality index and the high frequency of healing, without sequels, suggest that the treatment with serum neutralized the poison, indicating the efficacy of this treatment against snakebites by the specific species found in this region.

  10. Six degree of freedom sensor

    Vann, Charles S.

    1999-01-01

    This small, non-contact optical sensor increases the capability and flexibility of computer controlled machines by detecting its relative position to a workpiece in all six degrees of freedom (DOF). At a fraction of the cost, it is over 200 times faster and up to 25 times more accurate than competing 3-DOF sensors. Applications range from flexible manufacturing to a 6-DOF mouse for computers. Until now, highly agile and accurate machines have been limited by their inability to adjust to changes in their tasks. By enabling them to sense all six degrees of position, these machines can now adapt to new and complicated tasks without human intervention or delay--simplifying production, reducing costs, and enhancing the value and capability of flexible manufacturing.

  11. Physicians with MBA degrees: change agents for healthcare improvement.

    Science.gov (United States)

    Lazarus, Arthur

    2010-01-01

    Increasingly, physicians gravitating toward the fields of quality improvement and healthcare management are seeking MBA degrees to supplement their medical training. Approximately half of all U.S. medical schools offer combined MD-MBA degrees, and numerous executive MBA programs exist for physicians in practice. Physicians who enter management are considered change agents for healthcare improvement, yet they receive little support and encouragement from their medical teachers and practicing colleagues. This situation can be rectified by placing greater value on the role of business-trained physicians and subsidizing their tuition for business school.

    2011-09-01

    A ceramic slurry that contains a 6H-type Ba(Ti0.95Mn0.05)O3 powder was casted into a plaster mold under 10 T magnetic field to form a green compact of (0001)-oriented Ba(Ti0.95Mn0.05)O3. After sintering the green compact at 1300 °C in air, it was confirmed that the (0001)-oriented 6H-type perovskite structure transformed to a (111)-oriented 3C-type perovskite structure. The structural transformation was again examined using hexagonal BaTiO3 prepared by reducing pseudo-cubic BaTiO3 powder in H2 atmosphere. In this case, the preferred (0001) orientation was not confirmed for the green compacts. After sintering the green compacts at 1300 °C in air, mixed crystal orientations of (100)/(001) and (111) were observed for the resultant tetragonal BaTiO3 ceramics. This (100)/(001) orientation was suppressed by annealing the hexagonal BaTiO3 powder at 1000 °C before slip-casting, leading to highly (111)-oriented ceramics. It was found that the green compacts of (0001)-oriented hexagonal BaTiO3 can transform into (111)-oriented tetragonal BaTiO3 ceramics, maintaining the macroscopic crystal orientations due to a similar atomic stacking along [0001] of 6H-type BaTiO3 and [111] of 3C-type BaTiO3.

    Yamaki, M.; Furuta, M.; Doi, T.; Shimoyama, J.; Horii, S.

    Magnetic alignment is a new crystal alignment process which enables tri-axial orientation without epitaxial growth at room temperature. In order to investigate the effectiveness of this magnetic tri-axial alignment process, we attempted to fabricate tri-axially oriented ErBa2Cu4O8 (Er124) ceramics by a slip-casting technique under two different modulated rotation magnetic fields (MRFs); uni-directional rotation type and oscillation type. For improvement of the degrees of tri-axial orientation in the Er124 green compacts slip-casted under MRFs, appropriate choice of sample-rotation method, magnetic field condition, control of mean diameter of source powders, and viscosity of slurry was found to be important in the case of MRFs induced by the sample-rotation. At the current stage, the degree of inplane orientation with ∼10̊ in Er124 was achieved.

    2015-01-01

    Full Text Available This paper focuses on changes that have been noticed in hotel offer of Belgrade during first decade of 21st century. It will be shown that these changes are associated with characteristics of tourism demand, reason of tourists visit and their behavior during the stay. Changes are expressed not only in the rise of number of beds but also in the structural changes of hotel offer in Belgrade. As one of major destinations in Serbia which attracts the majority of foreign and a great deal of domestic guests, Belgrade had to change hotel offer quantitatively as well as qualitatively. Also, this paper will focus on the influence of business tourism development on hotel offer. Business tourism is in tight relationship with changes identified and presented in this paper. Business tourists present a major group of tourists in Belgrade and it is expected to remain so in the following years. The strategy of tourism development of Belgrade and developing of tourism investments back up these statements that will be shown in this paper.

    Yamagishi, Toshio; Horita, Yutaka; Takagishi, Haruto; Shinada, Mizuho; Tanida, Shigehito; Cook, Karen S

    2009-07-14

    In a series of experiments, we demonstrate that certain players of an economic game reject unfair offers even when this behavior increases rather than decreases inequity. A substantial proportion (30-40%, compared with 60-70% in the standard ultimatum game) of those who responded rejected unfair offers even when rejection reduced only their own earnings to 0, while not affecting the earnings of the person who proposed the unfair split (in an impunity game). Furthermore, even when the responders were not able to communicate their anger to the proposers by rejecting unfair offers in a private impunity game, a similar rate of rejection was observed. The rejection of unfair offers that increases inequity cannot be explained by the social preference for inequity aversion or reciprocity; however, it does provide support for the model of emotion as a commitment device. In this view, emotions such as anger or moral disgust lead people to disregard the immediate consequences of their behavior, committing them to behave consistently to preserve integrity and maintain a reputation over time as someone who is reliably committed to this behavior.

  5. Offer as a creative foundation of direct marketing

    2010-01-01

    Full Text Available Investments into communications mix are specific because besides significant financial resources it also involves creative marketing ideas that are a result of imagination and experience. However, the application of direct marketing communication mix is like 'a cave on iceberg'. The visible aspect presented through promotional content is only a small part of the whole process including experts from different fields. The process of creation a new communication mix of direct marketing must fully use all the challenges posed by sophisticated technology. Direct marketing depicted by new technology (cable television, telemarketing and the Internet can substantially increase the competitive advantage of enterprises in attracting their customer's attention and creating their loyalty as well. The companies use the mentioned media more frequently in order to create such offers that will lead towards strengthening loyalty of the existing customers, while simultaneously attracting those customers who were previously making purchases with our direct competitors. Hence, an offer as a creatively designed marketing vehicle proposes a number of potential benefits to a client. However, the client will be able to claim those benefits only in the case when a customer takes action as suggested by a communicated message. Basically, those are 'the rules of the game' that regulate relationship between company and client in direct marketing. Creating offers which guide the process of direct marketing is in the domain of customer relations management. Without an attractive offer, consumers will not create any type of measurable response to a company and therefore relations with clients would never emerge. On the other hand, if a company fails to continuously follow client's needs and wants, those engaged in direct sales will not be able to create adequate offers that would satisfy clients and motivate them to repeat purchases. .

    2013-01-01

    The quest for improved neutron capture cross sections for advanced reactor concepts, transmutation of radioactive wastes as well as for astrophysical scenarios of neutron capture nucleosynthesis has motivated new experimental efforts based on modern techniques. Recent measurements in the keV region have shown that a 4p BaF2 detector represents an accurate and versatile instrument for such studies. The present work deals with the potential of such a 4p BaF2 detector in combination with spallation neutron sources, which offer large neutron fluxes over a wide energy range. Detailed Monte Carlo simulations with the GEANT package have been performed to investigate the critical backgrounds at a spallation facility, to optimize the detector design, and to discuss alternative solutions.

  18. Establishing a framework for a physician assistant/bioethics dual degree program.

    Science.gov (United States)

    Carr, Mark F; Bergman, Brett A

    2014-01-01

    : Numerous medical schools currently offer a master of arts (MA) in bioethics dual degree for physicians. A degree in bioethics enhances the care physicians provide to patients and prepares physicians to serve on ethics committees and consult services. Additionally, they may work on institutional and public policy issues related to ethics. Several physician assistant (PA) programs currently offer a master of public health (MPH) dual degree for PAs. A degree in public health prepares PAs for leadership roles in meeting community health needs. With the success of PA/MPH dual degree programs, we argue here that a PA/bioethics dual degree would be another opportunity to advance the PA profession and consider how such a program might be implemented. The article includes the individual perspectives of the authors, one of whom completed a graduate-level certificate in bioethics concurrently with his 2-year PA program, while the other served as a bioethics program director.

    Full Text Available A bank loan is the main form of economical credit. It is for corporate activities – for medium and big companies and for retail activities – for small companies and individuals. The conditions for credit mainly depend on the quality of customers, it means their ability to perform a profitable activity and to be able to pay back the credits. For reasons which are mainly connected to marketing, bank practice has developed a large range of credit names, trying to emphasize some of the parts of the products or to take profit of some competition advantages in relation with customers’ products. We are trying to include the offer of bank loans in a typology which takes into account the law, the bank field rules and the main technical features of the offered products.

    Full Text Available After the launching of a Fundamentals of Physics course offered for different campuses of the National University of Colombia in blended learning mode, various experiences were collected in a virtual assessment that were supported 100% by ICT. We implemented an evaluation system that consists of different categories ranging from traditional examinations, partial examinations, final examinations, workshops, quizzes, attendance, and duties and forums, all evaluated online. In particular, random blocks of questions were used for examinations taken from large databases, built especially for this purpose, on the order of 100 per chapter. We comment on the results achieved with the implementation of the evaluation system proposed, in addition to the possibilities offered and the risks they present.

  1. CORPORATE MOTIVES FOR PUBLIC SHARES OFFERING DURING THE FINANCIAL CRISIS

    Directory of Open Access Journals (Sweden)

    Mihaela Grubisic Seba

    2015-06-01

    Full Text Available Despite greater constraints for obtaining bank loans, public shares’ offerings ceased in the SEE region since the onset of the financial crisis in 2008. With scarce IPOs and SEOs as well as debt offerings, Croatian capital market stands as prime example of mandatory shares’ listing rule application. Surveys of CFOs on going-public vs staying-private decisions are rare even in developed countries and are mostly conducted during the hot IPO markets. In this paper the motives of shares’ issuance are compared between publicly- and privately-held companies during the financial crisis. Research results showed that companies would not issue shares to the public to raise funds for their investments and growth.

    2013-01-01

    The International Space Station offers unique capabilities for earth remote sensing. An established Earth orbiting platform with abundant power, data and commanding infrastructure, the ISS has been in operation for twelve years as a crew occupied science laboratory and offers low cost and expedited concept-to-operation paths for new sensing technologies. Plug in modularity on external platforms equipped with structural, power and data interfaces standardizes and streamlines integration and minimizes risk and start up difficulties. Data dissemination is also standardized. Emerging sensor technologies and instruments tailored for sensing of regional dynamics may not be worthy of dedicated platforms and launch vehicles, but may well be worthy of ISS deployment, hitching a ride on one of a variety of government or commercial visiting vehicles. As global acceptance of the urgent need for understanding Climate Change continues to grow, the value of ISS, orbiting in Low Earth Orbit, in complementing airborne, sun synchronous polar, geosynchronous and other platform remote sensing will also grow.

    To evaluate whether the support offered by maternity hospitals is associated with higher prevalences of exclusive and predominant breastfeeding. This is a cross-sectional study including a representative sample of 916 infants less than six months who were born in maternity hospitals, in Ribeirao Preto, Sao Paulo, Southeastern Brazil, 2011. The maternity hospitals were evaluated in relation to their fulfillment of the Ten Steps to Successful Breastfeeding. Data were collected regarding breastfeeding patterns, the birth hospital and other characteristics. The individualized effect of the study factor on exclusive and predominant breastfeeding was analyzed using Poisson multiple regression with robust variance. Predominant breastfeeding tended to be more prevalent when the number of fulfilled steps was higher (p of linear trend = 0.057). The step related to not offering artificial teats or pacifiers to breastfed infants and that related to encouraging the establishment of breastfeeding support groups were associated, respectively, to a higher prevalence of exclusive (PR = 1.26; 95%CI 1.04;1.54) and predominant breastfeeding (PR = 1.55; 95%CI 1.01;2.39), after an adjustment was performed for confounding variables. We observed a positive association between support offered by maternity hospitals and prevalences of exclusive and predominant breastfeeding. These results can be useful to other locations with similar characteristics (cities with hospitals that fulfill the Ten Steps to Successful Breastfeeding) to provide incentive to breastfeeding, by means of promoting, protecting and supporting breastfeeding in maternity hospitals.

  11. Drug offers as a context for violence perpetration and victimization.

    2014-01-01

    Drug use has been linked empirically with and aggression and violence among youth in national and State of Hawai'i samples. However, the nature of this link and its implications for prevention are unclear. Therefore, this article explores the intersection of drugs with aggression and violence by using the drug offer context as the unit of analysis. Native Hawaiian youth are sampled because substance use rates tend to be higher and onset tends to be earlier for them than for their non-Hawaiian peers. Fourteen sex-specific focus group discussions were held with rural Native Hawaiian middle school students (N = 64). Students discussed what they think they would do in terms of drug refusal strategies in a variety of drug offer contexts. Although aggression and violence were perceived to be socially inappropriate, students nonetheless felt drug use would be less socially competent. Narrative analyses indicated that aggression and violence were thought to function as potential drug refusal strategies. As proximal drug resistance, aggression and violence perpetration served as an immediate deterrent to the drug offerer and thus drug use. As distal drug resistance, victimization served as a rationale for avoiding drug using contexts. Implications are discussed in terms of prevention policy and practice, specifically in terms of a school-based prevention curriculum. Future research in Hawaiian epistemology and gendered approaches are warranted.

    Academic education is generally rewarded by employers, but what happens to graduates if they are trained for two years less and have to compete with vocationally trained labor market entrants in a similar field of study? Focusing on Germany, we analyze labor market entries of individuals eligible...... training degrees, and with higher prestige (but similar earnings) than further vocational degrees. However, bachelor’s degrees from universities are also related to higher risks of unemployment or fixed-term employment. Universities of applied sciences, which combine academic and practical training, offer...... both high earnings and prestigious jobs as well as low risks of unemployment or fixed-term employment at the bachelor’s and the master’s level. Overall, ‘general’ academic education provides advantages over vocational education, despite these structural changes. Variations by field of study...

  13. World Migration Degree Global migration flows in directed networks

    CERN Document Server

    Porat, Idan

    2015-01-01

    In this article we analyze the global flow of migrants from 206 source countries to 145 destination countries (2006-2010) and focus on the differences in the migration network pattern between destination and source counters as represented by its degree and weight distribution. Degree represents the connectivity of a country to the global migration network, and plays an important role in defining migration processes and characteristics. Global analysis of migration degree distribution offers a strong potential contribution to understanding of migration as a global phenomenon. In regard to immigration, we found that it is possible to classify destination countries into three classes: global migration hubs with high connectivity and high migration rate; local migration hubs with low connectivity and high migration rate; and local migration hubs with opposite strategy of high connectivity and low migration rate. The different migration strategies of destination countries are emerging from similar and homogenies p...

  14. Octa-coordination and the hydrated Ba2+(aq) ion

    Chaudhari, Mangesh I; Rempe, Susan B

    2014-01-01

    The hydration structure of Ba^{2+} ion is important for understanding blocking mechanisms in potassium ion channels. Here, we combine statistical mechanical theory, ab initio molecular dynamics simulations, and electronic structure methods to calculate the hydration free energy and local hydration structure of Ba^{2+}(aq). The predicted hydration free energy (-302.9$\\pm$0.7 kcal/mol) matches the experimental value (-302.56 kcal/mol) when the fully occupied and exclusive inner solvation shell is treated. In the local environment defined by the inner and first shell of hydrating waters, Ba^{2+} is directly coordinated by eight (8) waters. Octa-coordination resembles the structure of Ba^{2+} and K^+ bound in potassium ion channels, but differs from the local hydration structure of K^+(aq) determined earlier.

    (Abridged)One of the fundamental challenges for astrophysics in the 21st century is finding a way to untangle the physical processes that govern galaxy formation and evolution. Given the importance and scope of this problem, the multi-wavelength astronomical community has used the past decade to build up a wealth of information over specific extragalactic deep fields to address key questions in galaxy formation and evolution. These fields generally cover at least 10square degrees to facilitate the investigation of the rarest, typically most massive, galaxies and AGN. Furthermore, such areal coverage allows the environments to be fully accounted for, thereby linking the single halo to the two-halo terms in the halo occupation distribution. Surveys at radio wavelengths have begun to lag behind those at other wavelengths, especially in this medium-deep survey tier. However, the survey speed offered by the JVLA means that we can now reach a point where we can begin to obtain commensurate data at radio wavelengths...

    Highlights: •Established the structural and magnetic phase diagram for CaBa (Co{sub 1−x}Al{sub x}){sub 4}O{sub 7}. •Lattice and the spin degrees of freedom are relatively decoupled in CaBaCo{sub 4}O{sub 7}. •Al doping suppresses short-range magnetic correlations which is observed well above T{sub C} in CaBaCo{sub 4}O{sub 7}. -- Abstract: We report the effects of Al-doping on the structure and magnetic properties in CaBa (Co{sub 1−x}Al{sub x}){sub 4}O{sub 7} (0 ⩽ x ⩽ 0.25). The system exhibits a structural transition from an orthorhombic symmetry to a hexagonal symmetry when the Al content exceeds x = 0.1. The Curie temperature and the value of the magnetization decrease with increasing Al doping level, indicating that the ferrimagnetic ground state is gradually suppressed. The ground state eventually transits into a spin-glass state for x > 0.1. Moreover, the short-range magnetic correlations, which occur at high temperatures in CaBaCo{sub 4}O{sub 7}, are found to be gradually suppressed with increasing Al content and eventually disappear for x = 0.25. By comparing our results with other Co-site doping cases, we suggest that the lattice and the spin degrees of freedom are relatively decoupled in CaBaCo{sub 4}O{sub 7}.

    We describe methods used to validate data from the Y.T. Lee Array for Microwave Background Anisotropy (AMiBA), an interferometric array designed to measure the Sunyaev-Zel'dovich effect and the anisotropy of the Cosmic Microwave Background (CMB). We perform several statistical tests on data from pointed galaxy cluster observations taken in 2007 and noise data from long-term blank sky observations and measurements with the feeds covered by the absorbers. We apply power spectrum analysis, cross power spectrum analysis among different outputs with different time lags in our analog correlator, and sample variance law tests to noise data. We find that (1) there is no time variation of electronic offsets on the time scale of our two-patch observations (~10 minutes); (2) noise is correlated by less than 10% between different lags; and (3) the variance of noise scales with the inverse of time. To test the Gaussianity of the data, we apply Kolmogorov-Smirnov (K-S) tests to cluster data, and find that a 5% significance...

    Full Text Available In comparison with the previous structure determination of the β-modification of barium catena-polyphosphate that was based on Weissenberg film data [Grenier et al. (1967. Bull. Soc. Fr. Minéral. Cristallogr. 90, 24–31], the current CCD-data-based redetermination reveals all atoms with anisotropic displacement parameters, standard uncertainties for the atomic coordinates, and the determination of the absolute structure. Moreover, a much higher accuracy in terms of the bond-length distribution for the polyphosphate chain, with two shorter and two longer P—O distances, was achieved. The structure consists of polyphosphate chains extending parallel to [100] with a periodicity of two PO4 tetrahedra. The Ba2+ cations are located between the chains and are surrounded by ten O atoms in the form of a distorted coordination polyhedron, with Ba—O distances ranging from 2.765 (3 to 3.143 (3 Å, also reflecting the higher precision of the current redetermination.

    Isotopic studies of many elements from the uranium ore natural nuclear reactors at Oklo provide useful information on the migration of radioactive nuclides. The fissiogenic isotopic composition of Ba is particularly interesting, as it is an important indication in the search for fissiogenic Cs. In this report we detail the detection of remarkable isotopic deviations of Ba in the Oklo samples and estimate the geochemical behaviour of fissiogenic Cs from excess Ba isotopes. Six samples systematically collected from borehole SF84 (zone 10) at the Oklo uranium mine have been analyzed. Isotopic deviations of Ba indicate the existence of fissiogenic Cs and Ba. A good correlation between the elemental abundance of Cs and isotopic abundances of excess 135Ba and 137Ba suggests that fissiogenic 135Ba and 137Ba behaved as Cs rather than Ba.

    Use of starch solution as feed for butanol bioconversion processes employing Clostridium beijerinckii BA101 may have added economic advantage over the use of glucose. Acetone butanol ethanol (ABE) was produced from 30 gL(-1) starch solution using a continuous process. The bioreactor was fed at a dilution rate of 0.02 h(-1) and starch solution/feed volume (3 L) was replaced every 72 h. The continuous reactor fed with cornstarch solution (feed temperature 19 degrees C) produced approximately 6.0 gL(-1) total ABE. Increasing the feed storage temperature to 37 degrees C improved ABE production to 7.2 gL(-1) suggesting that retrogradation was occurring more rapidly at 19 degrees C. In both these cases the fermentation drifted toward acid production after approximately 260 h, consistent with the retrogradation of starch overtime. The use of soluble starch, which is less prone to retrogradation, resulted in the production of 9.9 gL(-1) ABE at 37 degrees C feed storage temperature, as compared to 7.2 gL(-1) ABE when cornstarch was used. It should be noted that gelatinized starch retrogradation takes place after sterilization and prior to use of the feed medium, and does not occur during long-term storage of the raw corn material in the months leading up to processing. The degree of hydrolysis of gelatinized starch decreased from 68.8 to 56.2% in 3 days when stored at 37 degrees C. Soluble starch which does not retrograde demonstrated no change in the degree of hydrolysis.

    2012-03-01

    Scaling up for alternative energy such as solar, wind, and biofuel raises a number of environmental issues, notably changes in land use and adverse effects on wildlife. Airports offer one of the few land uses where reductions in wildlife abundance and habitat quality are necessary and socially acceptable, due to risk of wildlife collisions with aircraft. There are several uncertainties and limitations to establishing alternative energy production at airports, such as ensuring these facilities do not create wildlife attractants or other hazards. However, with careful planning, locating alternative energy projects at airports could help mitigate many of the challenges currently facing policy makers, developers, and conservationists.

    The Automated Container Offering System (TACOS) is a cargo booking assistant currently being fielded in the International Traffic Directorate of the Military Traffic Management Command (MTMC). The expert system automates the selection process for type and size of SEAVAN containers, ports, carrier, and ship for containerized military cargo moving from the continental US to Europe. It is designed to perform all processing on simple cases and provide assistance to the human booker on complex cases. MTMC processes requests for {approximately}1000 containers per week on these routes. This paper is a case history which describes factors guiding development of TACOS to illustrate several themes which occur in other (military) logistics expert system projects.

    2013-01-01

    Full Text Available Peptic ulcers are produced by an imbalance between gastro-duodenal mucosal defense mechanisms and damaging forces of gastric acid and pepsin, combined with superimposed injury from environmental or immunologic agents. Most common symptoms of peptic ulcer disease are abdominal discomfort, gnawing ache, occurs 2 to 3 hours after meal, other symptoms includes weight loss, poor appetite, bloating, nausea, vomiting etc. Some time duodenal wall perforates; bleeding due to the ulcer breaks blood vessels and obstructs the path of food trying to leave the stomach. Various studies have shown the association of Helicobacter pylori with peptic ulcers. Probiotic lactic acid bacteria are proposed to cure peptic ulcers by reducing colonization of H. pylori with stomach wall and by eradicating already established infection. A bacteriocin producing probiotic strain of P. acidilactici BA28 was evaluated for its antimicrobial activity against a number of Gram-positive and Gram-negative pathogens. Bacteriocin BA28 was partially purificated and characterized following in vitro assays. Preliminary investigations against H. plyori have suggested its effectiveness against peptic ulcer disease and therefore could be exploited to develop novel therapeutics.

  1. Structure and Properties of Modified and Charge-Compensated Chalcogenide Glasses in the Na/Ba-Ga-Ge Selenide System

    Science.gov (United States)

    Mao, Alvin W.

    3 to GeSe 2 results in the preferential formation of Ge-Ge bonds, which are distributed such that the clustering of ethane-like (Se3)Ge-Ge(Se3) units is avoided to the maximum extent. This behavior is entirely consistent with the continuously-alloyed structural scenario of chalcogenide glasses. However, for contents of Ga2Se3 greater than about 25--30 mol%, the avoidance of Ga-Ga and mixed Ga-Ge bonds results in the appearance of three-coordinated Se as an alternate mechanism to accommodate the Se deficiency. The addition of either Na2Se or BaSe to Ga2Se 3--GeSe2 glasses introduces an ionic bonding character to an otherwise largely covalently bonded network. As a result, the structure responds by adopting characteristics of the charge-compensated structural scenario of oxide glasses. In the stoichiometric Na2Se/BaSe--Ga 2Se3--GeSe2 glasses, the ratio of Na 2Se/BaSe:Ga2Se3 = 1 serves as a chemical threshold, where the network consists predominantly of corner-sharing (Ga/Ge)e4 tetrahedra, and the charge on the Na(Ba) cations is balanced by the GaSe4- tetrahedra. For glasses with Na 2Se/BaSe:Ga2Se3 1, the addition of Na2Se/BaSe results in the formation of non-bridging Se atoms, which break up the connectivity of the glassy network. The major difference between the modifying elements Na and Ba is that the high field strength of the Ba cation induces a higher degree of chemical disorder in the glass network. This conclusion is evidenced by the presence of some Ge-Ge bonds in BaSe--Ga2Se3--GeSe2 glasses even at the chemical threshold composition of BaSe:Ga2Se3 = 1. The structural duality of the Na2Se/BaSe--Ga2Se 3--GeSe2 system is best observed in the off-stoichiometric BaSe--Ga2Se3--GeSe2+/-Se glasses. Here, the removal of Se from a stoichiometric glass with BaSe:Ga2Se 3 > 1 results in Ge-Ge bonds, while its addition in excess of stoichiometry forms Se-Se bonds. Although such behavior is consistent with the continuously-alloyed structural model, it should be contrasted

    Creative, dynamic strategies are the ones that identify new and better ways of uniquely offering the target customers what they want or need. A business can achieve competitive advantage if it chooses a marketing strategy that sets the business apart from anyone else. Healthcare services companies have to understand that the customer should be placed in the centre of all specific marketing operations. The brand message should reflect the focus on the patient. Healthcare products and services offered must represent exactly the solutions that customers expect. The touchpoints with the patients must be well mastered in order to convince them to accept the proposed solutions. Healthcare service providers must be capable to look beyond customer's behaviour or product and healthcare service aquisition. This will demand proactive and far–reaching changes, including focusing specifically on customer preference, quality, and technological interfaces; rewiring strategy to find new value from existing and unfamiliar sources; disintegrating and radically reassembling operational processes; and restructuring the organization to accommodate new typess of work and skill.

    The electricity retail business has always been exposed to a significant risk due to a very volatile nature of the wholesale electricity market. Recently, this trend has been accelerating, as electricity-forward price can rise or fall during one day by an amount comparable to the retailer's margin. As a result, the risk that arises from sales contract offer maturity can significantly reduce or even neutralize the retailer's profit. To develop a mitigation strategy for this risk, a retailer clearly needs a model for a detailed risk analysis. Many attempts have been made to analyze several risk issues of an electricity retail company, but so far none has explored and evaluated the sales contract offer maturity risk. This paper presents a fundamental model for evaluating this risk and a methodology for its use, and compares its analytical performance with traditional techniques obtained from the option-pricing theory. A realistic example illustrates the use and the benefits of the proposed model in risk analysis of the electricity retail business. (author)

  5. Market Timing, lifecycle stage and Seasoned Equity offerings

    Full Text Available The tradeoff theory suggests that companies must issue shares to investments, when its leverage index is greater than your target rate, while the pecking order theory predicts that when capital offerings occur, the capital will be used to finance investments as the last source of funding, after their debt capacity have been exhausted. In contrast, the market timing theory predicts arguments that companies will adopt opportunistic behavior by issuing shares to take advantage of the high prices of the shares. Although the market timing theory has a significant influence on the decision to make a SEO, Brazilian literature contains little evidence about their economic importance and their effects. Thus, the present research aims to fill this gap in the Brazilian scenario. Specifically, we sought to assess the explanatory power of the relationship of market timing and the lifecycle theory in the issuance of SEO, which predicts that young companies with high market-to-book (MB and low operating cash flow sell shares to finance the investment, while mature companies, with low MB, pay dividends and fund investment internally. The sample was composed by non-financial companies with shares traded on BM&FBovespa. As main results, we can conclude that there is relationship between SEO and MB and size. On the other hand, were not observed evidence confirming the relationship between lifecycle stage and stock return, both in the previous year, and the year following the completion of the offer.

Explaining spatiality has been in the focus of tourism geographers since the beginnings, and the examination of spatial processes still represents a major challenge for researchers, knowing that there is no segment in the functioning of society in which spatiality is not present. The approach was to consider tourism as a complex spatial phenomenon, in order to explain better its processes. Romanian literature abounds in descriptive research of travel and tourism, discussing quantitative and qualitative issues, attraction classifications, tourism potential and geographic dispersal. However, a serious deficit manifests in explanatory research. Therefore, this paper aims to analyze the territorial disparities in the tourism offer of Romania, in generally and of Northern Transylvania in particularly, in the light of current trends characterizing the national tourism industry. Besides spatial characteristics, this paper also deals with tourism penetration on regional level, and territorial concentration of accommodation capacity in the region of Northern Transylvania. The results show that in the moderately-high saturated destination of Northern Transylvania the accommodation capacity in use is spatially concentrated and only a few localities can be regarded as the strongholds of the accommodation basis. The study brings novel results especially for tourism planning, but also provides a basis for further research.

    Full Text Available Pesquizamos, no figado e baço de dez casos puros de ancilostomose, elementos hemocitopoieticos; verificamos o peso do baço em 23 casos de individuos com idades compreendidas entre 3 e 60 anos; não encontramos, em nenhum caso, celulas hemoformadoras no figado. Em sete casos, encontramos, no baço, elementos da série vermelha em adiantado estado de evolução (eritroblastos ortocromaticos de nucleo picnotico. Em alguns destes casos observamos megacariocitos e numerosos mielocitos eosinofilos. Os tres casos que não apresentavam metaplasia mieloide no baço, eram os de individuos acima de 50 anos de idade. Entretanto, em outro caso de um individuo com 59 anos esta metaplasia foi verificada. Em individuos acima de 20 anos, o peso médio do baço, em nove casos, mostrou-se igual ao peso normal. Em 14 casos, compreendidos entre 3 e 14 anos, o peso deste orgão foi sempre sensivelmente mais elevado que nos normais de idade correspondente. Estes resultados sugerem a possibilidade de ser a metaplasia mieloide responsavel pelos aumentos de pezo nos baços de individuos jovens, vitimados pela anemia ancilostomica. A notavel proliferação dos eritroblastos ortocromaticos mostra que o grão e a rapidez da regeneração sanguinea, após a administração de ferro, são devidos, essencialmente, á grande quantidade de hemoglobina já preformada no baço e na medula ossea dos organismos ancilostomados.

    The modification of Ba in BaCl compounds from alkaline-metal to transition- and half-metal behavior is explored. High-pressure structural changes in BaCl are predicted using an ab initio structure search method. Dynamically stable bcc and R -3 m forms of BaCl are predicted at 15 and 10 GPa, respectively. The BaCl forms are more stable than elemental Ba plus BaC l2 above ˜10 GPa. Ba in stable BaCl adopts transition-metal properties via an s -d transition. At ambient pressure the fcc structure is ferromagnetic, and the bcc structure is half metallic and ferromagnetic. The transition-metal electronic structure found is sufficient to support superconductivity, with Tc as high as 3.4 K near ambient pressure.

    Cold and ultracold molecules offer a wide array of possibilities for precision measurement, molecular quantum chemistry, and studies many-body physics. Recently, cold beams of many molecular species have been created via cryogenic buffer gas cooling. Paired with laser cooling, this method can yield a molecular magneto-optical trap (MOT). We report progress toward a barium monohydride (BaH) cold molecular beam and MOT, including identification of cooling transitions in the B2 Σ molecules and construction of the cryogenic beam apparatus. The large mass ratio of the constituent atoms makes this system attractive for studies of ultracold fragmentation via coherent transfer to weakly bound states and subsequent photo- or magneto-dissociation, resulting in ultracold hydrogen.

In both soil cadmium is more easily lost.Key-words: copper, cadmium, mathematical model, environmental impact.

  15. Offering Behavioral Assistance to Latino Students Demonstrating Challenging Behaviors

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Challenging behaviors can significantly alter the learning environment of any classroom. Traditionally, schools have implemented practices that remove the offending student from the classroom, deliver punitive disciplinary actions, or refer the student to special education evaluation. Unfortunately, such practices have demonstrated little longitudinal effectiveness, with detrimental outcomes for the referred student, particularly students from Latino backgrounds. With enrollment projections indicating Latinos will become the majority in U.S. schools, educators are presented with the opportunity to shift away from past practices and implement evidence-based practices that concurrently assist students while addressing challenging behaviors. In this paper, the authors discuss past disciplinary practices, the adverse effects on Latino students, and offer recommendations on implementing functional behavioral assessment as a means to better meet the needs of Latino students demonstrating challenging behaviors.

    2011-01-01

    This article reviews the trends in positions of internal medicine resident (IMR) assigned to nephrology in Spain from 1985 to 2008. We analyse the number of positions, the changes of average points received (435 to 377), and the average position for nephrology (253 to 3457). We also observed the distribution by sex for the candidates (from 42% to 72% feminisation) over the 24 years examined. Nephrology is positioned 29th of the 47 specialities offered on Spanish IMR training programmes. These data should be an indication to all nephrologists that change is needed. We must examine which factors are involved in the lessening interest in Nephrology as a career among medical graduates and then strive to resolve the problems.

  18. Alternating-Offer Bargaining Games over the Gaussian Interference Channel

    CERN Document Server

    Liu, Xi

    2010-01-01

    This paper tackles the problem of how two selfish users jointly determine the operating point in the achievable rate region of a two-user Gaussian interference channel through bargaining. In previous work, incentive conditions for two users to cooperate using a simple version of Han-Kobayashi scheme was studied and the Nash bargaining solution (NBS) was used to obtain a fair operating point. Here a noncooperative bargaining game of alternating offers is adopted to model the bargaining process and rates resulting from the equilibrium outcome are analyzed. In particular, it is shown that the operating point resulting from the formulated bargaining game depends on the cost of delay in bargaining and how bargaining proceeds. If the associated bargaining problem is regular, a unique perfect equilibrium exists and lies on the individual rational efficient frontier of the achievable rate region. Besides, the equilibrium outcome approaches the NBS if the bargaining costs of both users are negligible.

    Full Text Available This paper investigates changes in long-term operational and financial performance for a sample of Brazilian companies made initial public offerings (IPO's shares, in the period 2002-2008. This period showed a historically high number of IPOs, a heavily discontinued phenomenon with the international financial crisis of 2008. As performance measures were chosen six financial indicators usually adopted in the literature in periods of three years pre-IPO, year of listing and three years post-IPO. The indicators evaluated were size, growth rate, profitability, financial leverage, investment level and investment rate. The results show evidence that, on average, there were statistically significant improvements in size, profitability, investment level and investment rate. But there was no evidence statistically significant changes in the growth rate and financial leverage after the IPO of Brazilian firms.

  20. What Does Behavioral Genetics Offer for Improving Educaton?

    Science.gov (United States)

    Panofsky, Aaron

    2015-01-01

    For much of its history, behavioral genetics, or research into the influence genetics has on human behavior, has been associated with a pessimistic view of educational reforms' potential to make much difference in improving educational outcomes or reducing inequality. Recently, however, some behavioral geneticists have begun to speak in more optimistic terms about the promise of genetically informed education to improve learning for all children, especially those who are socially or economically disadvantaged. This shift in emphasis should be welcome news for everyone interested in promoting educational improvement who worried that behavioral genetics offered support for the status quo. However, I think it amounts to little more than a shift in tone. Behavioral genetics, I will argue, does not advance educational reform: its proposed solutions are rooted in the limits, not the strength, of behavioral genetics knowledge; repeat the ideas of earlier U.S. educational reform efforts; and rely on a naive optimism about the power of choice and personalization.

    2016-12-16

    This article is part of a project investigating chiropractors' beliefs on the role of vitalism in their philosophical and practice approaches and how that might contribute to addressing current epidemics of non-communicable diseases. It aims to present atomism, reductionism, materialism and mechanism as fundamental ontologies in biomedicine and to examine what role these might play in its struggle to deal with these epidemics; to present vitalism as a fundamental ontology existing in chiropractic along with these ontologies of biomedicine; and to discuss how imbalances in the use of these ontologies and practices stemming from them might be contributing to difficulties in addressing these epidemics. The use of more balanced approaches by chiropractors involving not only mechanistic biomedical ontologies but also an increased focus on vitalism might offer value in addressing these epidemics and should be investigated.

    The purpose of this descriptive study was to identify specific information related to U.S. dental hygiene baccalaureate degree completion programs. Learning experiences, assessment methods, and baccalaureate institutional partnerships were assessed. Of the sixty dental hygiene programs that offer a degree completion program, the forty-two that met the inclusion criteria (including having operated for at least three years) were invited to participate in a thirty-eight item online survey. A 62 percent (n=26) response rate was obtained. Learning experiences in responding programs included core dental hygiene courses, general education courses, and elective dental hygiene courses. Emphasis areas offered by various programs were in the specialty areas of education, public or community health, and research. Respondents reported that their graduates were employed in multiple settings (65 percent; n=17), with 19 percent (n=5) reporting employment in the combined grouping of private practice, education, and public health. Institutional partnerships included articulation agreements (88 percent; n=21), community college baccalaureate (8 percent; n=2), and university extension (4 percent; n=1) models. The findings of this study provide a baseline for assessing the educational composition and design of U.S. dental hygiene degree completion programs. However, results of this study showed inconsistencies among learning experiences that might raise concerns when considering students' level of preparation for graduate education and future leadership roles in the profession.

    The probability of achieving long term remission for patients with refractory acute leukaemia is very low. Allogeneic stem cell transplantation (SCT) is offered to these patients in order to improve their dismal outcome. We retrospectively analyzed 361 acute leukaemia patients, who underwent allogeneic SCT in the Hadassah's bone marrow transplantation department between the years 2005 and 2012 and identified 84 patients with active leukaemia at transplantation. Median age was 34 years. Sixty four patients were diagnosed with acute myeloid leukaemia (AML), 18 patients with acute lymphoblastic leukaemia and two with biphenotypic leukaemia. The majority of patients were diagnosed with de-novo AML and transplanted at relapse. In the surviving patients, median follow up was 15 months. One year OS was 20%. At time of last follow up, 13 patients were alive (15.5%): ten patients with AML and two patients with acute lymphoblastic leukaemia. In the univariate analysis, factors associated with significantly better overall survival were as follows: matched unrelated donor (p = 0.006), matched donor (p = 0.014) and occurrence of acute graft-versus-host disease (aGVHD) (p = 0.019). Karnofsky performance score at SCT and occurrence of cGVHD were found to be borderline significant. Only matched unrelated donor and aGVHD were found to affect overall survival significantly in the multivariate analysis. Other than performance score at SCT, none of the pretransplant patients' characteristics were found to influence survival. In conclusion, as none of the pretransplant characteristics were found to influence the ability to select the patients that will benefit from HSC transplantation, this work supports offering HSCT to all active leukaemia eligible patients with reasonable performance status.

    Accurate determination of walking capacity is important for the clinical diagnosis and management plan for patients with peripheral arterial disease. The current "gold standard" of measurement is walking distance on a treadmill. However, treadmill testing is not always reflective of the patient's natural walking conditions, and it may not be fully accessible in every vascular clinic. The objective of this study was to determine whether Google Maps, the readily available GPS-based mapping tool, offers an accurate and accessible method of evaluating walking distances in vascular claudication patients. Patients presenting to the outpatient vascular surgery clinic between November 2013 and April 2014 at the Ottawa Hospital with vasculogenic calf, buttock, and thigh claudication symptoms were identified and prospectively enrolled in our study. Onset of claudication symptoms and maximal walking distance (MWD) were evaluated using four tools: history; Walking Impairment Questionnaire (WIQ), a validated claudication survey; Google Maps distance calculator (patients were asked to report their daily walking routes on the Google Maps-based tool runningmap.com, and walking distances were calculated accordingly); and treadmill testing for onset of symptoms and MWD, recorded in a double-blinded fashion. Fifteen patients were recruited for the study. Determination of walking distances using Google Maps proved to be more accurate than by both clinical history and WIQ, correlating highly with the gold standard of treadmill testing for both claudication onset (r = .805; P Google Maps tool was also efficient, with reporting times averaging below 4 minutes. For vascular claudicants with no other walking limitations, Google Maps is a promising new tool that combines the objective strengths of the treadmill test and incorporates real-world walking environments. It offers an accurate, efficient, inexpensive, and readily accessible way to assess walking distances in patients with

    Yttrium-doped BaZrO{sub 3} (BZY) was processed by a simple yet effective chemical synthesis route that yielded perfectly spherical particles. The particle size was found to decrease with increasing molar concentration of cations in the solution. Thus, the process offered a great ease of controlling the particle size as well. The close control over morphology and size can provide an opportunity of tuning the properties of such particles. The average particle size as obtained from high-resolution scanning electron microscopy (HR-SEM) was 243, 206, 149, and 79 nm at 0.2, 0.5, 0.8, and 1 M concentration, respectively. At a processing temperature of 60 C, the undesirable phases, BaCO{sub 3} and Zr{sub 1-x}Y{sub x}O{sub 2}, were present along with BZY even after calcination at 600 C, and it took a very long processing time (160 min) for complete phase formation. The BZY phase formed within 45 min at a reaction temperature of 90 C and yielded phase pure powders on calcination at the same temperature (600 C). The d-spacing (2.98 Aa) obtained from the lattice fringes in high-resolution transmission electron microscopy (HR-TEM) confirmed the cubic perovskite phase of BaZrO{sub 3}. The average crystallite size calculated from XRD analysis coupled with the TEM observations revealed that each spherical particle consists of only few crystallites. (orig.)

    Polycrystalline samples of LaSr{sub 1-x}Ba{sub x}NiO{sub 4} show a crossover from a state with metallic transport properties for x = 0 to an insulating state as x{yields}1. The end member LaBaNiO{sub 4} with a nominal nickel Ni 3d{sup 7} configuration might therefore be regarded as a candidate for an antiferromagnetic insulator. However, we do not observe any magnetic ordering in LaBaNiO{sub 4} down to 1.5 K, and despite its insulating transport properties several other physical properties of LaBaNiO{sub 4} resemble those of metallic LaSrNiO{sub 4}. Based on an analysis of electrical and thermal-conductivity data as well as magnetic-susceptibility and low-temperature specific-heat measurements, we suggest that LaBaNiO{sub 4} is a Fermi glass with a finite electron density of states at the Fermi level but these states are localized.

    Thermophysical properties of barium thorium trioxide (BaThO{sub 3}) prepared by the solid-state reaction method were studied. The average linear thermal expansion coefficient of BaThO{sub 3} measured in the temperature range of room temperature to 1073 K was estimated as α = 11.9 × 10{sup −6} K{sup −1} by using a high-temperature X-ray diffraction technique. The longitudinal sound velocity, shear sound velocity, and thermal diffusivity of BaThO{sub 3} were measured. Further, the shear modulus, Young’s modulus, bulk modulus and Debye temperature were evaluated from the measured sound velocities. Using the laser flash technique, the thermal diffusivity of BaThO{sub 3} was measured in the temperature range of room temperature to 1073 K. The thermal conductivity of BaThO{sub 3} was evaluated from the heat capacity, thermal diffusivity, and density to be 2.3–3.4 Wm{sup −1} K{sup −1} in the temperature range of room temperature to 1073 K.

    Several data products, analysis software packages, and visualization tools have been released by the The Mediterranean Oceanic Data Base (MODB), a group that prepares hydrographic data sets and climatological fields for distribution to scientists working in the Mediterranean Sea.The climatological distributions of temperature and salinity in the Mediterranean that are available account for the regional properties of the water masses(Figure 1). These measurements should help refine the Mediterranean sector of the Climatological Atlas of the World Ocean published by S. Levitus in 1982. The Mediterranean gridded fields are represented in ASCII format on a 1/4-degree grid and 19 levels on the vertical. The data sets also include the hydrographic profiles from which the analyzed fields were derived.

    2016-01-01

    A majority of studied models for scale-free networks have degree distributions with exponents greater than $2$. Real networks, however, can demonstrate essentially more heavy-tailed degree distributions. We explore two models of scale-free equilibrium networks that have the degree distribution exponent $\\gamma = 1$, $P(q) \\sim q^{-\\gamma}$. Such "superfat-tailed" degree distributions can be identified in empirical data only if the mean degree of a network is sufficiently high. Our models exploit a rewiring mechanism. They are local in the sense that no knowledge of the network structure, apart from the immediate neighbourhood of the vertices, is required. These models generate uncorrelated networks in the infinite size limit, where they are solved explicitly. We investigate finite size effects by the use of simulations. We find that both models exhibit disassortative degree-degree correlations for finite network sizes. In addition, we observe a markedly degree-dependent clustering in the finite networks. We i...

    We have recently begun a program of high precision measurements of Key production and destruction reactions of important radiochemical diagnostic isotopes, including several isotopes of uranium, plutonium and americium. The detector for advanced neutron capture experiments (DANCE), a 4{pi} BaF{sub 2} array located at the Los Alamos Neutron Science Center, will be used to measure the neutron capture cross sections for most of the isotopes of interest. However, neutron capture measurements on many of the actinides are complicated by the presence of prompt {gamma}-rays arising from low energy neutron-induced fission, which competes with neutron capture to varying degrees. Previous measurements of {sup 235}U using the DANCE array have shown that we can partially resolve capture from fission events based on total {gamma}-ray calorimetry (i.e. total {gamma}-ray energy versus {gamma}-ray multiplicity). The addition of a dedicated fission-tagging detector to the DANCE array has greatly improved our ability to separate these two competing processes. In addition to higher quality neutron capture data, the addition of a fission-tagging detector offers a means to determine the capture-to-fission ratio ({sigma} {sub {gamma}}/{sigma} {sub f}) in a single measurement, which should reduce the effect of systematic uncertainties. We are currently using a dual parallel-plate avalanche counter (PPAC) with the target material electro-deposited directly on the center cathode foil. This design provides a high efficiency for detecting fission fragments and allows loading of pre-assembled target/detector assemblies into the neutron beam line at DANCE. Results from tests of the fission-tag detector, as well as preliminary results from measurements on {sup 235}U and {sup 252}Cf that utilized the fission-tag detector will be presented.

    Full Text Available BaCO3 particles coated with amorphous TiO2 precursor are prepared by a wet chemical method to produce BaTiO3 nanoparticles at low temperatures. Subsequently, we investigate the formation behavior of BaTiO3 particles and the particle growth behavior when the precursor is subjected to heat treatment. The state of the amorphous TiO2 coating on the surface of BaCO3 particles depends on the concentration of NH4HCO3, and the optimum concentration is found to be in the range 0.5–1.0 M. Thermogravimetric curves of the BaCO3 particles coated with the TiO2 precursor, prepared from BaCO3 particles of various sizes, show BaTiO3 formation occurring mainly at 550–650 °C in the case of fine BaCO3 particles. However, as evidenced from the curves, the temperature of formation of BaTiO3 shifts to higher values with an increase in the size of the BaCO3 particles. The average particle size of single phase BaTiO3 at heat-treatment temperature of 650–900 °C is observed to be in the range 60–250 nm.

    Mn/Ba/Al2O3 catalyst for NO oxidation-storage and Pt/Ba/Al2O3 catalyst mixed with Mn/Ba/Al2O3 for NOx storage-reduction by hydrogen were investigated. The results showed that Mn/Ba/Al2O3 had large nitrogen oxides storage capacity (397.9 μmolg-1) under lean bum condition.When Pt/Ba/Al2O3 catalyst was mixed with Mn/Ba/Al2O3 in equal weight proportion, the NOx conversion increased between 250 ℃ and 500 ℃ under the dynamic lean-rich bum conditions, and the maximum NOx conversion increased from 95.4% to 98.2%. Mn/Ba/Al2O3 has promoted NOx storing in the lean stage and improved NOx reduction efficiency in the rich stage, these might result in higher NOx conversion over the low Pt loading content catalyst.

    As a “battle-tested and bomb-scarred” Chinese writer, Ba Jin has had many pieces of writings featuring Japan' s mass bombing campaigns on the Chinese soil. Through his depiction, the inhuman cruelties of the Japa- nese aggressors were exposed to the full, and the indestructible spirit of the Chinese people and army united with bitter hatred against the common enemy was eulogized. The type of literary works by Ba Jin featuring the Japanese air raids is of special significance in the history of Chinese literature both in terms of the literary expression of the scale and degree of atrocities of the mass bombing campaigns and with reference to the artistic altitude that Ba Jin has attained.%作为一位“身经百炸”的作家,巴金留下了大量关于轰炸的作品,既控诉了日军惨无人道的暴行,也讴歌了中国人民面对轰炸的同仇敌忾。无论是就对轰炸表现的全面,还是就艺术上所达到的高度而言,巴金的这类作品都有其文学史上的特别意义。

    For the spectral analysis of high-resolution and high-signal-to-noise (S/N) spectra of hot stars, state-of-the-art non-local thermodynamic equilibrium (NLTE) model atmospheres are mandatory. These are strongly dependent on the reliability of the atomic data that is used for their calculation. Reliable Ba V - VII oscillator strengths are used to identify Ba lines in the spectra of the DA-type white dwarf G191-B2B and the DO-type white dwarf RE0503-289 and to determine their photospheric Ba abundances. We newly calculated Ba V - VII oscillator strengths to consider their radiative and collisional bound-bound transitions in detail in our NLTE stellar-atmosphere models for the analysis of Ba lines exhibited in high-resolution and high-S/N UV observations of G191-B2B and RE0503-289. For the first time, we identified highly ionized Ba in the spectra of hot white dwarfs. We detected Ba VI and Ba VII lines in the Far Ultraviolet Spectroscopic Explorer (FUSE) spectrum of RE0503-289.

    Electronic cigarettes as possibly healthier alternative to conventional cigarettes are gaining popularity worldwide, although they are still hazardous to human health. Partly it is caused by unregulated advertising and online sales. Unfortunately it is more and more popular for youth to try electronic cigarettes. The aim of the study was to assess the marketing claims used by Polish websites offering electronic cigarettes. A search using Google search engine was performed in July 2015 for two keywords: e-papierosy [e-cigarettes] and elektroniczne papierosy [electronic cigarettes]. First 150 websites (15 pages) were listed. After initial review 86 pages met all inclusion criteria and were included in the study. Pages were searched for presence of 13 selected marketing claims as well as age-related warning and any social websites connections. Age-related warning was present on only 33.72% (n=29) websites. Two thirds has its own Facebook fan-page with average 1922.09 ± 3634.86 likes. Articles about health are available on 10.46% (n=9) websites, 53.49% (n=46) states that e-cigarettes are healthier than conventional ones, 39.53% (n=34) emphasized that during usage of e-cigarettes no tarry substances are produced. Two pages had special article in which conventional and electronic cigarettes were compared. Almost half (44.19%) remarked that e-cigarettes are cheaper in usage than conventional, one third pointed out the simplicity of usage. 32.56% advertised e-cigarettes as aid in quitting smoking. One fourth stated that e-cigarettes are harmless for surroundings. 33.72% marketed them as a way of bypassing public smoking act. 56.98% remarked the variety of liquid tastes offered. Electronic cigarettes and their rising popularity create another new possible threat for public health as the widely available information emphasize safety of e-cigarettes usage and as their availability and usage is not limited or restricted by law. electronic cigarettes, e-cigarettes, internet

    2016-03-01

    We describe a simple experimental apparatus for laser ablation of barium monohydride (BaH) molecules and the study of their rovibrational spectra relevant to direct laser cooling. BaH is a promising candidate for laser cooling and ultracold fragmentation, both of which are precursors to novel experiments in many-body physics and precision measurement. We present a detailed analysis of the properties of ablation plumes that can improve the understanding of surface ablation and deposition technologies. A range of absorption spectroscopy and collisional thermalization regimes has been studied. We directly measured the Franck-Condon factor of the B 2Σ+(v'=0 ) ←X 2Σ+(v''=1 ) cycling transition. Prospects for production of a high luminosity cryogenic BaH beam are outlined.

    The BaBar Collaboration has operated an instrumented flux return (IFR) system covering over 2000 m sup 2 with resistive plate chambers (RPCs) for nearly 3 years. The chambers are constructed of bakelite sheets separated by 2 mm. The inner surfaces are coated with linseed oil. This system provides muon and neutral hadron detection for BaBar. Installation and commissioning were completed in 1998, and operation began mid-year 1999. While initial performance of the system reached design, over time, a significant fraction of the RPCs demonstrated significant degradation, marked by increased currents and reduced efficiency. A coordinated effort of investigations have identified many of the elements responsible for the degradation. This article presents our current understanding of the aging process of the BaBar RPCs along with the action plan to combat performance degradation of the IFR system.

    The BaBar detector has operated over 200 2nd generation Resistive Plate Chambers (RPCs) in the forward endcap since 2002. Many chambers have increased noise rates and high voltage currents. These aging symptoms are correlated with the integrated RPC current as expected, but also depend on the rate and direction of the gas flow, indicating that pollutants produced in the gas can accelerate aging of downstream RPC surfaces. HF produced by decomposition of the Freon 134a component of the BaBar RPC gas in electric discharges has been proposed as the main pollutant. This paper presents measurements of HF production and absorption rates in BaBar RPCs. Since many of the highest rate chambers in the forward endcap were converted to avalanche mode operation, a comparison of HF production in streamer and avalanche mode RPCs is made. Correlations between the HF production rate and other chamber operating conditions were also explored.

    The central drift chamber for the BaBar detector at the SLAC B-factory is based on a hexagonal cell design with 7104 cells arranged in 40 layers and drift gas Helium:isobutane (80%:20%). Performance optimization and integration requirements led to an electronics design that mounts the amplifier-descriminator and digitizing circuitry directly on the endplate. High channel density is achieved using a 4-channel custom amplifier-discriminator IC and an 8-channel custom CMOS TDC/FADC IC on a single circuit board. Data read from the ends are multiplexed on 4 fiber optic links, and prompt trigger data are sent out continuously on 24 links. Analysis of cosmic ray data demonstrates that the electronics design meets the performance goals for the BaBar drift chamber. The final electronics were installed on the drift chamber in July, 1998. Installation of BaBar on beamline is scheduled for March, 1999.

    2000-09-01

    Considering Coulomb and proximity potentials as barriers, we have calculated the half lives for 12C emission from various Ba isotopes using different mass tables. The half life for 112Ba isotope calculated by us is 6.020 × 103 s which is comparable with the experimental value 5.620 × 103 s. From our study it is found that 114Ba is the good parent for 12C emission whose emission rate is favorable for measurement. The half lives predicted by us lie very close to those reported by Shanmugam et al using their cubic plus Yukawa plus exponential model. It is observed that inclusion of proximity potential does not produce significant deviation from the linear nature of the Geiger–Nuttall plots. Also it is found that the neutron excess in the parent nuclei slows down the exotic decay process.

    The physical interpretation of the spectral line polarization produced by the joint action of the Hanle and Zeeman effects offers a unique opportunity to obtain empirical information about hidden aspects of solar and stellar magnetism. To this end, it is important to achieve a complete understanding of the sensitivity of the emergent spectral line polarization to the presence of a magnetic field. Here we present a detailed theoretical investigation on the role of resonance scattering and magnetic fields on the polarization signals of the Ba II D1 and D2 lines of the Fraunhofer spectrum at 4934 and 4554 Å, respectively. We adopt a three-level model of Ba II, and we take into account the hyperfine structure that is shown by the 135Ba and 137Ba isotopes. Despite their relatively small abundance (18%), the contribution coming from these two isotopes is indeed fundamental for the interpretation of the polarization signals observed in these lines. We consider an optically thin slab model, through which we can investigate in a rigorous way the essential physical mechanisms involved (resonance polarization, Zeeman, Paschen-Back, and Hanle effects), avoiding complications due to radiative transfer effects. We assume the slab to be illuminated from below by the photospheric solar continuum radiation field, and we investigate the radiation scattered at 90°, both in the absence and in the presence of magnetic fields, deterministic and microturbulent. We show in particular the existence of a differential magnetic sensitivity of the three-peak Q/I profile that is observed in the D2 line in quiet regions close to the solar limb, which is of great interest for magnetic field diagnostics.

  14. The kindest cut? Surgical castration, sex offenders and coercive offers.

    2014-09-01

    The European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment (CPT) have conducted visits and written reports criticising the surgical castration of sex offenders in the Czech Republic and Germany. They claim that surgical castration is degrading treatment and have called for an immediate end to this practice. The Czech and German governments have published rebuttals of these criticisms. The rebuttals cite evidence about clinical effectiveness and point out this is an intervention that must be requested by the sex offender and cannot occur without informed consent. This article considers a number of relevant arguments that are not discussed in these reports but which are central to how we might assess this practice. First, the article discusses the possible ways in which sex offenders could be coerced into castration and whether this is a decisive moral problem. Then, it considers a number of issues relevant to determining whether sex offenders are harmed by physical castration. The article concludes by arguing that sex offenders should not be coerced into castration, be that via threats or offers, but that there is no reason to think that this is occurring in the Czech Republic or Germany. In some cases, castration might be useful for reconfiguring a life that has gone badly awry and where there is no coercion, the European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment are mistaken about this being degrading treatment.

    Rice is an important crop and major model plant for monocot functional genomics studies. With the establishment of various genetic resources for rice genomics, the next challenge is to systematically assign functions to predicted genes in the rice genome. Compared with the robustness of genome sequencing and bioinformatics techniques, progress in understanding the function of rice genes has lagged, hampering the utilization of rice genes for cereal crop improvement. The use of transfer DNA (T-DNA) insertional mutagenesis offers the advantage of uniform distribution throughout the rice genome, but preferentially in gene-rich regions, resulting in direct gene knockout or activation of genes within 20-30 kb up- and downstream of the T-DNA insertion site and high gene tagging efficiency. Here, we summarize the recent progress in functional genomics using the T-DNA-tagged rice mutant population. We also discuss important features of T-DNA activation- and knockout-tagging and promoter-trapping of the rice genome in relation to mutant and candidate gene characterizations and how to more efficiently utilize rice mutant populations and datasets for high-throughput functional genomics and phenomics studies by forward and reverse genetics approaches. These studies may facilitate the translation of rice functional genomics research to improvements of rice and other cereal crops.

    2017-01-01

    As weight loss in primary care remains minimal, Health Professionals are advised to medically manage obesity-related risk factors including blood pressure and cholesterol. This experimental study evaluated the impact of medically managing risk factors on obese patients' motivation to change their behaviour. A vignette study with two arms: successful medical management (ie risk factors have improved) vs failed medical management (ie no change) set in three General Practices in the South of England. Overweight and obese patients (n=170) rated their behavioural intentions and beliefs after reading a vignette describing an overweight patient who had received either successful or failed medical management of their risk factors (blood pressure and cholesterol). Following successful medical management overweight and obese patients reported increased intentions to lose weight and a greater understanding of their condition. Medical management may change patient's understanding of their weight problem and motivate them to lose weight. Successful management relating to improvements in blood pressure and cholesterol may offer renewed hope and motivate obese patients to change their behaviour. This could be used as a teachable moment to encourage patients to see that obesity need not be an inevitable part of their lives. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  17. Resilience offers escape from trapped thinking on poverty alleviation.

    The poverty trap concept strongly influences current research and policy on poverty alleviation. Financial or technological inputs intended to "push" the rural poor out of a poverty trap have had many successes but have also failed unexpectedly with serious ecological and social consequences that can reinforce poverty. Resilience thinking can help to (i) understand how these failures emerge from the complex relationships between humans and the ecosystems on which they depend and (ii) navigate diverse poverty alleviation strategies, such as transformative change, that may instead be required. First, we review commonly observed or assumed social-ecological relationships in rural development contexts, focusing on economic, biophysical, and cultural aspects of poverty. Second, we develop a classification of poverty alleviation strategies using insights from resilience research on social-ecological change. Last, we use these advances to develop stylized, multidimensional poverty trap models. The models show that (i) interventions that ignore nature and culture can reinforce poverty (particularly in agrobiodiverse landscapes), (ii) transformative change can instead open new pathways for poverty alleviation, and (iii) asset inputs may be effective in other contexts (for example, where resource degradation and poverty are tightly interlinked). Our model-based approach and insights offer a systematic way to review the consequences of the causal mechanisms that characterize poverty traps in different agricultural contexts and identify appropriate strategies for rural development challenges.

    The poverty trap concept strongly influences current research and policy on poverty alleviation. Financial or technological inputs intended to “push” the rural poor out of a poverty trap have had many successes but have also failed unexpectedly with serious ecological and social consequences that can reinforce poverty. Resilience thinking can help to (i) understand how these failures emerge from the complex relationships between humans and the ecosystems on which they depend and (ii) navigate diverse poverty alleviation strategies, such as transformative change, that may instead be required. First, we review commonly observed or assumed social-ecological relationships in rural development contexts, focusing on economic, biophysical, and cultural aspects of poverty. Second, we develop a classification of poverty alleviation strategies using insights from resilience research on social-ecological change. Last, we use these advances to develop stylized, multidimensional poverty trap models. The models show that (i) interventions that ignore nature and culture can reinforce poverty (particularly in agrobiodiverse landscapes), (ii) transformative change can instead open new pathways for poverty alleviation, and (iii) asset inputs may be effective in other contexts (for example, where resource degradation and poverty are tightly interlinked). Our model-based approach and insights offer a systematic way to review the consequences of the causal mechanisms that characterize poverty traps in different agricultural contexts and identify appropriate strategies for rural development challenges.

    Human Papillomavirus is responsible for 4.8% of cancers, and is the main cause of cervical cancer. Cervical cancer can be reduced by mean of secondary prevention (PAP-test, HPV-DNA test), while through primary prevention (anti-HPV vaccine) the incidence of other HPV-attributable cancers can also be reduced. In Italy, anti-HPV vaccination is part of the immunization schedule in girls since 2008, and in 2017 it was extended to boys. However, vaccine coverage is decreasing nationwide. This study aims to examine anti-HPV vaccination practices in Health care services of Lazio Region, Italy. Questionnaires were sent or administered directly to those in charge of vaccinations. Data, collected from 11/12 (92%) Lazio Local Health Units and from 116 vaccination centers, show a remarkable diversity in the offer: 41% of the centers open only 1-2 days/week, 42% only in the morning, and only 7% are open on Saturday. Vaccination is available by reservation only in 62% of the centers, while vaccines are not administered to ≥18 years subjects in 33%; 93% of the centers call actively the girls in the target cohort, while 70% and 94% recall the patients who had not received the first or the second dose of vaccine, respectively. Collaboration with family physicians and/or pediatricians was declared by 80% of the centers. Vaccine coverage could probably be improved by addressing the highlighted critical issues and applying best practices widely.

    The Danish Microbiology Database (MiBa) is a national database that receives copies of reports from all Danish departments of clinical microbiology. The database was launched in order to provide healthcare personnel with nationwide access to microbiology reports and to enable real-time surveillance of communicable diseases and microorganisms. The establishment and management of MiBa has been a collaborative process among stakeholders, and the present paper summarises lessons learned from this nationwide endeavour which may be relevant to similar projects in the rapidly changing landscape of health informatics.

    An electron microscopy study has been carried out to characterize the microstructure of a sintered Gd-Ba-Cu-O superconductor alloy. The GdBa2Cu3O(7-x) phase in the oxygen annealed sample is orthorhombic, while in the vacuum annealed sample it is tetragonal. It is shown that the details of the fine structure in the 001-line zone axis convergent beam patterns can be used to distinguish between the orthorhombic form and the tetragonal form. In addition to this matrix phase, an amorphous phase is frequently observed at the triple grain junctions. Gd-rich inclusions have been observed inside the matrix phase.

    This article is based upon a thesis submitted in partial fulfilment of the requirements of Anglia Polytechnic University for the degree of Master of Philosophy. The study, completed in 1997, sought to identify factors making a positive contribution to learning within mental health care settings, and, having done this, to develop a means of auditing. Phase One drew on published work; however, it was necessary to determine the contextual validity of factors shown by colleagues to be conductive to learning, since the focus of this earlier work was, in the main, within general adult nursing. Information on the relevance of these factors was obtained from a sample (n = 146) of mental health nursing students, qualified staff, and teachers who responded to a self-completion postal survey, using a questionnaire as the research instrument. Phase Two drew upon the work completed in Phase One. A Likert-type scale audit instrument was developed and administered to a sample (n = 51) of mental health nursing students. In order to test the reliability of this instrument, students'verbal ratings of the quality of their learning experience were compared to numerical ratings provided by the audit instrument resultant from this study. Findings suggest that the instrument provides an effective, efficient means of evaluating learning environments from an individual student's perspective, and as a cumulative profile of student, practice setting and supervisors operating within it. This enables educationalists to identify standards which may be incorporated into future education/service provider contracting arrangements.

    The present study assessed the degree to which undergoing a mastectomy without reconstructive surgery negatively impacts the patient's psychological state. We focus on body image and self-esteem as well as the influence of mastectomy on patient sex lives and partnership relations. The participants were 60 women, either married or in a relationship, who had had a mastectomy because of breast cancer and no subsequent reconstructive surgery. A marital happiness questionnaire was used to evaluate the research problem. Surgery negatively impacted partnership relations for 33% of participants. In particular, 31% reported deterioration in attractiveness; 31%, a feeling of malaise; and 30%, that their partners perceived them as less attractive. Moreover, 80% in the youngest group reported that they covered their body during intimate contact, whereas 58% in the oldest age group reported the same behaviour. Deterioration in satisfaction with sex life and in the pleasure of sexual intercourse was indicated by 71% and 77%, respectively. Correspondingly, 71% also noticed a decrease in sexual activity, with 76% of participants aged 50-65 years reporting such a decline. The oldest women were also less satisfied with their sexual intercourse. Breast excision due to cancer negatively impacted the quality of sexual life for 71% of participants. Partnership relations after surgery remained unchanged for 67% of them. There was significant impact of surgery on the perception of one's own body. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available Solid solutions of (1−xBaTiO3-xBaSc1/2Nb1/2O3 (BT-BSN with x = 0.025, 0.05, 0.075, 0.1 and 0.125 were prepared by a high temperature solid-state reaction technique. The effects of the Ba(Sc1/2Nb1/2O3 addition on the phase composition, dielectric properties, as well as polarization-electric field (P-E loops of the BT-BSN solid solution were investigated. The room-temperature X-ray diffraction analyses of all the ceramics revealed a perovskite phase after sintering at 1350 °C with a composition-dependent symmetry. Temperature and frequency dependence of the dielectric permittivity and losses have been explored: ceramics of compositions x ≤ 0.075 showed normal ferroelectric behavior, while ceramics with x ≥ 0.1 were of relaxor type. The degree of diffuseness and the relaxor effect increase while the transition temperature (TC or Tm decreases when both scandium and niobium are introduced in the BaTiO3 lattice. Ceramics of composition x = 0.125 exhibited interesting relaxor characteristics at 10 kHz: ΔTm = 20 K, ɛr = 12,000, and Tm = 140 K. In addition, modeled using Vogel–Fülcher relation, this same composition showed the fitting parameters: Ea = 0.0503 eV, f0 = 1.129 × 1014 Hz and TVF = 166.85 K.

    The effect of Sn4+ (BaSnO3) B-site substitution on the microstructure and dielectric properties of Ba(Mg1/3Ta2/3)O3microwave ceramics was investigated. X-ray diffraction shows that a complex perovskite material Ba(Mg1/3Ta2/3)O3was prepared. As Sn4+ content x increases in the (1-x) Ba(Mg1/3Ta2/3)O3-xBaSnO3 (x=0.00~0.20) system, the dielectric constant generally keeps unchanged, while TCF changes from positive to negative. Although the addition of Sn4+ reduces the ordering degree, Qf0 is still increased when the ceramics density increases. This trend implies that Qf0 of this system is mostly determined by ceramics density rather than ordering degree. After sintering at 1500℃for 3 h, the system with x=0.15 was found to have excellent dielectric properties as follows: ε≈25, Qf0≥300,000 GHz at 7 GHz, TCF=-0.6×10-6/℃.

    We investigate the growth of a class of networks in which a new node first picks a mediator at random and connects with $m$ randomly chosen neighbors of the mediator at each time step. We show that degree distribution in such a mediation-driven attachment (MDA) network exhibits power-law $P(k)\\sim k^{-\\gamma(m)}$ with a spectrum of exponents depending on $m$. To appreciate the contrast between MDA and Barab\\'{a}si-Albert (BA) networks, we then discuss their rank-size distribution. To quantify how long a leader, the node with the maximum degree, persists in its leadership as the network evolves, we investigate the leadership persistence probability $F(\\tau)$ i.e. the probability that a leader retains its leadership up to time $\\tau$. We find that it exhibits a power-law $F(\\tau)\\sim \\tau^{-\\theta(m)}$ with persistence exponent $\\theta(m) \\approx 1.51 \\ \\forall \\ m$ in the MDA networks and $\\theta(m) \\rightarrow 1.53$ exponentially with $m$ in the BA networks.

    We investigate the growth of a class of networks in which a new node first picks a mediator at random and connects with m randomly chosen neighbors of the mediator at each time step. We show that the degree distribution in such a mediation-driven attachment (MDA) network exhibits power-law P(k) ∼k - γ(m) with a spectrum of exponents depending on m. To appreciate the contrast between MDA and Barabási-Albert (BA) networks, we then discuss their rank-size distribution. To quantify how long a leader, the node with the maximum degree, persists in its leadership as the network evolves, we investigate the leadership persistence probability F(τ) i.e. the probability that a leader retains its leadership up to time τ. We find that it exhibits a power-law F(τ) ∼τ - θ(m) with persistence exponent θ(m) ≈ 1.51 ∀ m in MDA networks and θ(m) → 1.53 exponentially with m in BA networks.

    Functional imaging studies have proposed a role for left BA37 in phonological retrieval, semantic processing, face processing and object recognition. The present study targeted the posterior aspect of BA37 to see whether a deficit, specific to one of the above types of processing could be induced....... Four conditions were investigated: word and nonword reading, colour naming and picture naming. Repetitive transcranial magnetic stimulation (rTMS) was delivered over posterior BA37 of the left and right hemispheres (lBA37 and rBA37, respectively) and over the vertex. divisions were significantly slower...... to name pictures when TMS was given over lBA37 compared to vertex or rBA37. rTMS over lBA37 had no significant effect on word reading, nonword reading or colour naming. The picture naming deficit is suggested to result from a disruption to object recognition processes. This study corroborates the finding...

    Barium titanate-based microwave dielectrics usually require relatively high temperatures to sinter, which prevents the use of base metals such as copper for electrodes. In this work, BaTi(4)O(9) microwave dielectric ceramics co-fired with copper electrodes are made possible by adding B-Si-Ba- Zn-O glass to induce liquid-phase sintering at sufficiently low temperature and in reduced atmosphere. The microstructures and electric properties of the BaTi(4)O(9) ceramics thus obtained are carefully examined and studied. Proper glass composition may significantly facilitate mass transportation in the low-temperature co-fired ceramic (LTCC) material, resulting in better densification without serious degradation of electric properties. Although the B2O3/SiO2 ratio enhances the glass mobility during sintering, the BaO/ZnO ratio contributes to the chemical affinity of glass to BaTi(4)O(9) ceramics. In addition, various Ba-Ti-O phases with different Ba/Ti ratios may be found in the specimen through the X-ray diffraction patterns when the BaO/ZnO ratio is varied. If the BaO/ZnO ratio is high and the glass flows easily in the material, the Ba(4)Ti(13)O(30) phase is formed. If the BaO/ZnO ratio is low and the glass flows easily in the material, the BaTi(6)O(13) phase appears. We find that glass-induced Ba(4)Ti(13)O(30) transformation may significantly decrease Qxf values in the BT4-BSBZ materials. Therefore, the appropriate glass composition must be selected to ensure the phase stability of dielectrics to achieve the best performance possible.

    The ionic disorder in single crystals of the fluorite-type solid solutions Ba1-xLaxF2+x (with x=0.209 and x=0.492) has been studied in the temperature range from room temperature to 800 degrees C by diffuse neutron scattering, ionic conductivity, and specific heat measurements. From the diffuse...... coincide at approximately 650 degrees C. At this temperature no clear anomaly is observed in the specific heat. Based on these findings the authors propose a conduction mechanisms where F- ions are moving through the lattice by means of rearrangements of the 222 clusters....

  13. Offering Global Collaboration Services beyond CERN and HEP

    The CERN IT department has built over the years a performant and integrated ecosystem of collaboration tools, from videoconference and webcast services to event management software. These services have been designed and evolved in very close collaboration with the various communities surrounding the laboratory and have been massively adopted by CERN users. To cope with this very heavy usage, global infrastructures have been deployed which take full advantage of CERN's international and global nature. If these services and tools are instrumental in enabling the worldwide collaboration which generates major HEP breakthroughs, they would certainly also benefit other sectors of science in which globalization has already taken place. Some of these services are driven by commercial software (Vidyo or Wowza for example), some others have been developed internally and have already been made available to the world as Open Source Software in line with CERN's spirit and mission. Indico for example is now installed in 100+ institutes worldwide. But providing the software is often not enough and institutes, collaborations and project teams do not always possess the expertise, or human or material resources that are needed to set up and maintain such services. Regional and national institutions have to answer needs, which are growingly global and often contradict their operational capabilities or organizational mandate and so are looking at existing worldwide service offers such as CERN's. We believe that the accumulated experience obtained through the operation of a large scale worldwide collaboration service combined with CERN's global network and its recently- deployed Agile Infrastructure would allow the Organization to set up and operate collaborative services, such as Indico and Vidyo, at a much larger scale and on behalf of worldwide research and education institutions and thus answer these pressing demands while optimizing resources at a global level. Such services would
