    Distributed applications require information to effectively utilize the network. Some of the information they require is the current and maximum bandwidth, current and minimum latency, bottlenecks, burst frequency, and congestion extent. This type of information allows applications to determine parameters like optimal TCP buffer size. In this paper, we present a cooperative information-gathering tool called the network characterization service (NCS). NCS runs in user space and is used to acquire network information. Its protocol is designed for scalable and distributed deployment, similar to DNS. Its algorithms provide efficient, speedy and accurate detection of bottlenecks, especially dynamic bottlenecks. On current and future networks, dynamic bottlenecks do and will affect network performance dramatically.

    Neocarzinostatin (NCS) is an enediyne antibiotic produced by Streptomyces carzinostaticus. The NCS chromophore consists of an enediyne core, a sugar moiety, and a naphthoic acid (NA) moiety. The latter plays a key role in binding the NCS chromophore to its apoprotein to protect and stabilize the bioactive NCS chromophore. In this study, we expressed three genes: ncsB (naphthoic acid synthase), ncsB3 (P450 hydroxylase), and ncsB1 (O-methyltransferase), in Streptomyces lividans TK24. The three genes were sufficient to produce 2-hydroxy-7-methoxy-5-methyl-1-naphthoic acid. Production was analyzed and confirmed by LC-MS and nuclear magnetic resonance. Here, we report the functional characterization of ncsB3 and thereby elucidate the complete biosynthetic pathway of NA moiety of the NCS chromophore. PMID:20735485

    We report on the Ag-, Fe-, and Co-doping of InP/ZnSe QDs using the growth-doping method. Doping the InP/ZnSe NCs with Ag caused a red-shift in the emission spectra with increasing dopant levels while the PL intensity decreased. Fe-doping resulted in blue-shifted emission spectra. The cobalt-doping (Co-doping) had no effect on the emission peak position. Instead, it had a quenching effect on the PL intensities. The HRTEM images showed well-defined lattice fringes for the doped InP/ZnSe NCs while the XRD analyses showed that they retained their zinc blende structure even after doping.

  4. Synthesis and characterization of polypyrrole/Sn-doped TiO2 nanocomposites (NCs) as a protective pigment

    International Nuclear Information System (INIS)

    We have chemically polymerized pyrrole in the presence of Sn-doped TiO2 nanoparticles (NPs) and TiO2 (NPs) which act as a protective pigment. Field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) results show a core-shell structure of pigments in which TiO2 and Sn-doped TiO2 NPs have a nucleus effect and caused a homogenous PPy core-shell type morphology leading to coverage of the TiO2 and Sn-doped TiO2 NPs by PPy deposit. The XRD results indicate that the crystalline size of polypyrrole/TiO2 NCs and polypyrrole/Sn-doped TiO2 NCs were approximately 93.46 ± 0.06 and 23.36 ± 0.06 nm respectively. The electrochemical impedance spectroscopy (EIS) results show that the performance of polypyrrole/Sn-doped TiO2 NCs is better than polypyrrole/TiO2 NCs. The results indicate that increasing the area of synthesized polypyrrole in the presence of Sn-doped TiO2 NPs can increase its ability to interact with the ions liberated during the corrosion reaction of steel in the presence of NaCl. The UV-vis results show that the band gap of TiO2 NPs increases with doped of Sn in lattice of TiO2. The increase of the band gap of TiO2 with doping of Sn can decrease the charge transfer through the coating.

    Reaction of copper(I) thiocyanate and triphenylphosphane with the bidentate Schiff base N,N'-bis(trans-2-nitrocinnamaldehyde)ethylenediamine {Nca2en, (1); systematic name (1E,1'E,2E,2'E)-N,N'-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]}, C20H18N4O4, in a 1:1:1 molar ratio in acetonitrile resulted in the formation of the complex {(1E,1'E,2E,2'E)-N,N'-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]-κ(2)N,N'}(thiocyanato-κN)(triphenylphosphane-κP)copper(I)], [Cu(NCS)(C20H18N4O4)(C18H15P)] or [Cu(NCS)(Nca2en)(PPh3)], (2). The Schiff base and copper(I) complex have been characterized by elemental analyses, IR, electronic and (1)H NMR spectroscopy, and X-ray crystallography [from synchrotron data for (1)]. The molecule of (1) lies on a crystallographic inversion centre, with a trans conformation for the ethylenediamine unit, and displays significant twists from coplanarity of its nitro group, aromatic ring, conjugated chain and especially ethylenediamine segments. It acts as a bidentate ligand coordinating via the imine N atoms to the Cu(I) atom in complex (2), in which the ethylenediamine unit necessarily adopts a somewhat flattened gauche conformation, resulting in a rather bowed shape overall for the ligand. The NCS(-) ligand is coordinated through its N atom. The geometry around the Cu(I) atom is distorted tetrahedral, with a small N-Cu-N bite angle of 81.56 (12)° and an enlarged opposite angle of 117.29 (9)° for SCN-Cu-P. Comparisons are made with the analogous Schiff base having no nitro substituents and with metal complexes of both ligands. PMID:26146396

    It is reported here, for the first time, that high-quality bulk size (18 × 5 × 4 mm3) single crystals of a new nonlinear optical crystal, [(NH4)[Cd(NCS)3]·C12H24O6] [Ammonium (18-crown-6-ether) Cadmium(II) tri-thiocyanate; ACCTC], have been grown from aqueous solution via slow evaporation technique. Solubility of ACCTC has been determined for various temperatures. The grown crystals were characterized by single crystal X-ray diffraction, FT-IR, FT-Raman, and UV-Vis-NIR studies. ACCTC crystallizes in orthorhombic system with cell parameters a = 14.7568 Ǻ, b = 15.4378 Ǻ, and c = 10.6383 Ǻ with space group Cmc21. The optical second-harmonic generation effect has been measured by using the Kurtz powder technique and is found to be 2 times higher than that of KDP (KH2PO4). The sample possesses wide optical transparency range from 200 to 2,500 nm. The TG-DSC thermal analysis revealed that the sample is thermally stable up to 237.92 °C, which is comparatively far better than the thermal stability of [(18C6)Li][Cd(SCN)3]; CLTC (170 °C).

    In this work, CdTe@CdS NCs were synthesized using a thermochemical approach and synthesized NCs were used as an emissive layer, a light emitting device, with ITO/MoO3/PVK/CdTe@CdS(core-shell)/Mg:Ag structure. Structural and optical properties of synthesized NCs were investigated by means of XRD, UV–Vis and photoluminescence (PL) analyses. Fabricated device was characterized by electroluminescence spectra. XRD analysis demonstrated cubic phase NCs. Photoluminescence spectra showed a narrow band emission with a peak centred at about 600 nm. Fabricated device showed an emission at 600 nm, which is related to CdTe@CdS NCs. Turn on voltage of fabricated device is about 8 V and brightness is 53.7 Cd/m2 at a working voltage of about 14.57 V.

    A 2:2:1:6 molar ratio of Zn(ClO 4) 2·6H 2O, tris(2-aminoethyl)amine (tren), Zn(ClO 4) 2·6H 2O/Cu(ClO 4) 2·6H 2O and NH 4NCS in methanol-water solution mixtures affords homo-/heterobimetallic compounds of the type [Zn(tren)NCS] 2[M(NCS) 4] (M = Zn, 1; M = Cu, 2) which have been characterized using microanalytical, spectroscopic, magnetic and other physicochemical results. The structures of the compounds are determined by X-ray diffraction measurements. Structural analyses reveal that 1 and 2 are isomorphous and consist of two discrete [Zn(tren)NCS] + cations and a [M(NCS) 4] 2- (M = Zn/Cu) anion. Zinc(II) centers in the [Zn(tren)NCS] + units adopt distorted trigonal bipyramidal geometry with ZnN 5 chromophores coordinated through four N atoms of tren and one N atom of terminal thiocyanate. Each metal(II) center in [M(NCS) 4] 2- has a distorted tetrahedral coordination environment with an MN 4 chromophore ligated by four N atoms of the terminal thiocyanates. In solid state, doubly N-H…S hydrogen bonded 1D chains of [Zn(tren)NCS] + cations are interconnected by tetrahedral [Zn(NCS) 4] 2-/[Cu(NCS) 4] 2- anions through cooperative N-H…S and N-H…N (in 1) and N-H…S and C-H…S (in 2) hydrogen bonds resulting in 3D network structures. Establishment of such networks seems to be aiding the crystallization.

  12. Regiospecific O-methylation of naphthoic acids catalyzed by NcsB1, an O-methyltransferase involved in the biosynthesis of the enediyne antitumor antibiotic neocarzinostatin.

    Neocarzinostatin, a clinical anticancer drug, is the archetypal member of the chromoprotein family of enediyne antitumor antibiotics that are composed of a nonprotein chromophore and an apoprotein. The neocarzinostatin chromophore consists of a nine-membered enediyne core, a deoxyaminosugar, and a naphthoic acid moiety. We have previously cloned and sequenced the neocarzinostatin biosynthetic gene cluster and proposed that the biosynthesis of the naphthoic acid moiety and its incorporation into the neocarzinostatin chromophore are catalyzed by five enzymes NcsB, NcsB1, NcsB2, NcsB3, and NcsB4. Here we report the biochemical characterization of NcsB1, unveiling that: (i) NcsB1 is an S-adenosyl-L-methionine-dependent O-methyltransferase; (ii) NcsB1 catalyzes regiospecific methylation at the 7-hydroxy group of its native substrate, 2,7-dihydroxy-5-methyl-1-naphthoic acid; (iii) NcsB1 also recognizes other dihydroxynaphthoic acids as substrates and catalyzes regiospecific O-methylation; and (iv) the carboxylate and its ortho-hydroxy groups of the substrate appear to be crucial for NcsB1 substrate recognition and binding, and O-methylation takes place only at the free hydroxy group of these dihydroxynaphthoic acids. These findings establish that NcsB1 catalyzes the third step in the biosynthesis of the naphthoic acid moiety of the neocarzinostatin chromophore and further support the early proposal for the biosynthesis of the naphthoic acid and its incorporation into the neocarzinostatin chromophore with free naphthoic acids serving as intermediates. NcsB1 represents another opportunity that can now be exploited to produce novel neocarzinostatin analogs by engineering neocarzinostatin biosynthesis or applying directed biosynthesis strategies.

    Neuromorphic hardware offers an electronic substrate for the realization of asynchronous event-based sensory-motor systems and large-scale spiking neural network architectures. In order to characterize these systems, configure them, and carry out modeling experiments, it is often necessary to interface them to workstations. The software used for this purpose typically consists of a large monolithic block of code which is highly specific to the hardware setup used. While this approach can lead to highly integrated hardware/software systems, it hampers the development of modular and reconfigurable infrastructures thus preventing a rapid evolution of such systems. To alleviate this problem, we propose PyNCS, an open-source front-end for the definition of neural network models that is interfaced to the hardware through a set of Python Application Programming Interfaces (APIs). The design of PyNCS promotes modularity, portability and expandability and separates implementation from hardware description. The high-level front-end that comes with PyNCS includes tools to define neural network models as well as to create, monitor and analyze spiking data. Here we report the design philosophy behind the PyNCS framework and describe its implementation. We demonstrate its functionality with two representative case studies, one using an event-based neuromorphic vision sensor, and one using a set of multi-neuron devices for carrying out a cognitive decision-making task involving state-dependent computation. PyNCS, already applicable to a wide range of existing spike-based neuromorphic setups, will accelerate the development of hybrid software/hardware neuromorphic systems, thanks to its code flexibility. The code is open-source and available online at https://github.com/inincs/pyNCS. PMID:25232314

    Current and future energy demands, end uses, and cost used to characterize typical applications and resultant services in the industrial sector of the United States and 15 selected states are examined. A review and evaluation of existing industrial energy data bases was undertaken to assess their potential for supporting SERI research on: (1) market suitability analysis, (2) market development, (3) end-use matching, (3) industrial applications case studies, and (4) identification of cost and performance goals for solar systems and typical information requirements for industrial energy end use. In reviewing existing industrial energy data bases, the level of detail, disaggregation, and primary sources of information were examined. The focus was on fuels and electric energy used for heat and power purchased by the manufacturing subsector and listed by 2-, 3-, and 4-digit SIC, primary fuel, and end use. Projections of state level energy prices to 1990 are developed using the energy intensity approach. The effects of federal and state industrial energy conservation programs on future industrial sector demands were assessed. Future end-use energy requirements were developed for each 4-digit SIC industry and were grouped as follows: (1) hot water, (2) steam (212 to 300/sup 0/F, each 100/sup 0/F interval from 300 to 1000/sup 0/F, and greater than 1000/sup 0/F), and (3) hot air (100/sup 0/F intervals). Volume I details the activities performed in this effort.

They have been isolated by anionic metathesis of the respective perchlorate and thiocyanate salts with the Lindqvist type isopolyanions. The detailed spectroscopic (IR, UV-visible and ESR) analyses have been performed on compounds 1 and 2 along with their unambiguous crystal structure determination. The polyoxometalate cluster anions not only serve as the counter anions but are also involved in extensive non-covalent interactions with the macrocyclic cationic complexes in their respective crystals. Phase homogeneity of the synthesized compounds in bulk has been established by the X-ray powder diffraction study. Thermal analysis has also been carried out on the title compounds.

    In this paper we present a preliminary model for the characterization of ICT services in a beyond 2020 perspective based on the particular properties ICT has as design material. The paper aims at unifying traditions from service research and service encounter research with the research traditions...... from Human Computer Interaction (HCI), interaction design, and user experience research. We suggest that the ICT in ICT-based service encounter no longer should be seen as neutral or transparent tool, as in existing literature, but as an independent element that essentially transform the service...... encounter. This is important for the design of future automated and intelligent ICT- based services....

    Zn(II), Cd(II) and Hg(II) complexes of N-methyl-N-phenyl dithiocarbamate have been synthesized and characterized by elemental analysis and spectral studies (IR, 1H and 13C-NMR). The single crystal X-ray structure of the mercury complex revealed that the complex contains a Hg centre with a distorted tetrahedral coordination sphere in which the dinuclear Hg complex resides on a crystallographic inversion centre and each Hg atom is coordinated to four S atoms from the dithiocarbamate moiety. One dithiocarbamate ligand acts as chelating ligand while the other acts as chelating bridging ligand between two Hg atoms, resulting in a dinuclear eight-member ring. The course of the thermal degradation of the complexes has been investigated using thermogravimetric and differential thermal analyses techniques. Thermogravimetric analysis of the complexes show a single weight loss to give MS (M = Zn, Cd, Hg) indicating that they might be useful as single source precursors for the synthesis of MS nanoparticles and thin films.

    Full Text Available This article presents a report on the experience of healthcare professionals in Florianópolis, who took the course La Atención Primaria de Salud y la Medicina Familiar en Cuba [Primary Healthcare and Family Medicine in Cuba], in 2014. The purpose of the study is to characterize the healthcare units and services provided by the Cuban National Healthcare System (SNS and to reflect on this experience/immersion, particularly on Cuba’s Primary Healthcare Service. The results found that in comparison with Brazil’s Single Healthcare System (SUS Cuba’s SNS Family Healthcare (SF service is the central organizing element of the Primary Healthcare Service. The number of SF teams per inhabitant is different than in Brazil; the programs given priority in the APS are similar to those in Brazil and the intersectorial nature and scope of the services prove to be effective in the resolution of healthcare problems.

  4. Modelling the protocol stack in NCS with deterministic and stochastic petri net

    Science.gov (United States)

    Hui, Chen; Chunjie, Zhou; Weifeng, Zhu

    2011-06-01

    Protocol stack is the basis of the networked control systems (NCS). Full or partial reconfiguration of protocol stack offers both optimised communication service and system performance. Nowadays, field testing is unrealistic to determine the performance of reconfigurable protocol stack; and the Petri net formal description technique offers the best combination of intuitive representation, tool support and analytical capabilities. Traditionally, separation between the different layers of the OSI model has been a common practice. Nevertheless, such a layered modelling analysis framework of protocol stack leads to the lack of global optimisation for protocol reconfiguration. In this article, we proposed a general modelling analysis framework for NCS based on the cross-layer concept, which is to establish an efficiency system scheduling model through abstracting the time constraint, the task interrelation, the processor and the bus sub-models from upper and lower layers (application, data link and physical layer). Cross-layer design can help to overcome the inadequacy of global optimisation based on information sharing between protocol layers. To illustrate the framework, we take controller area network (CAN) as a case study. The simulation results of deterministic and stochastic Petri-net (DSPN) model can help us adjust the message scheduling scheme and obtain better system performance.

    In this work, ZnSe and core–shell ZnSe@ZnS nanocrystals (NCs) were synthesized using a one-pot, rapid and room temperature photochemical method. UV illumination provided the required energy for the chemical reactions. Synthesized NCs were characterized using X-ray diffraction spectroscopy (XRD), transmission electron microscopy (TEM), UV–vis and photoluminescence (PL) spectroscopy. XRD pattern indicated cubic zinc blende structure for ZnSe NCs and the TEM image indicated round-shaped particles, most of which had a diameter of about 3 nm. Band gap of ZnSe NCs was obtained as about 3.6 eV, which was decreased by increasing the illumination time. Synthesized NCs indicated intensive and narrow emission in the UV-blue area (370 nm) related to the excitonic recombination and a broad band emission with a peak located at about 490 nm originated from the DAP (donor–acceptor pairs) recombination. ZnS shell was grown on ZnSe cores using a reaction based on the photo-sensitivity of Na2S2O3. For ZnSe@ZnS core–shell NCs, XRD diffraction peaks shifted to higher angles. TEM image indicated a shell around cores and most of the ZnSe@ZnS NCs have a diameter of about 5 nm. After the ZnS growth, ZnSe excitonic emission shifted to the longer wavelength and PL intensity was increased considerably. PL QY was obtained about 11% and 17% for ZnSe and ZnSe@ZnS core–shell QDs respectively. - Highlights: • A green photochemical approach was reported for synthesis of ZnSe NCs. • ZnS shell was grown around ZnSe using a new method. • Synthesis method was rapid, simple and at room temperature. • ZnSe NCs indicated a narrow UV-blue and a broad DAP emissions. • PL intensity was increased considerably by ZnS shell growth

    Full Text Available Abstract Background Schizophrenia is the major psychiatry disorder, which the exact cause remains unknown. However, it is well known that dopamine-mediated neurotransmission imbalance is associated with this pathology and the main target of antipsychotics is the dopamine receptor D2. Recently, it was described alteration in levels of two dopamine signaling related proteins in schizophrenic prefrontal cortex (PFC: Neuronal Calcium Sensor-1 (NCS-1 and DARPP-32. NCS-1, which is upregulated in PFC of schizophrenics, inhibits D2 internalization. DARPP-32, which is decreased in PFC of schizophrenics, is a key downstream effector in transducing dopamine signaling. We previously demonstrated that antipsychotics do not change levels of both proteins in rat's brain. However, since NCS-1 and DARPP-32 levels are not altered in wild type rats, we treated wild type PC12 cells (PC12 WT and PC12 cells stably overexpressing NCS-1 (PC12 Clone with antipsychotics to investigate if NCS-1 upregulation modulates DARPP-32 expression in response to antipsychotics treatment. Results We chronically treated both PC12 WT and PC12 Clone cells with typical (Haloperidol or atypical (Clozapine and Risperidone antipsychotics for 14 days. Using western blot technique we observed that there is no change in NCS-1 and DARPP-32 protein levels in both PC12 WT and PC12 Clone cells after typical and atypical antipsychotic treatments. Conclusions Because we observed no alteration in NCS-1 and DARPP-32 levels in both PC12 WT and Clone cells treated with typical or atypical antipsychotics, we suggest that the alteration in levels of both proteins in schizophrenic's PFC is related to psychopathology but not with antipsychotic treatment.

    A two-bit memory and quantized storage phenomenon are observed at room temperature for a device based on the traditional MOS structure with double-stacked Pt-nanocrystals (Pt-NCs). A 2.68 and 1.72 V flat band voltage shift (memory window) has been obtained when applying a ±7 V programming/erasing voltage to the structures with double-stacked Pt-NCs. The memory windows of 2.40 and 1.44 V can be retained after stress for 10(5) seconds, which correspond to 89.55% and 83.72% stored charges reserved. The quantized charge storage phenomenon characterized by current-voltage (J-V) hysteresis curves was detected at room temperature. The shrinkage of the memory window results from the decreasing tunneling probability, which strongly depends on the number of stacks. The traps, de-traps and quantum confinement effects of Pt-NCs may contribute to the improvement of dielectric characteristics and the two-bit memory behavior. The multi-bit memory and quantized storage behavior observed in the Pt-NCs stacks structure at room temperature might provide a feasible method for realizing the multi-bit storage in non-volatile flash memory devices.

  13. Construction of N, S codoped TiO2 NCs decorated TiO2 nano-tube array photoelectrode and its enhanced visible light photocatalytic mechanism

    International Nuclear Information System (INIS)

    Highlights: • N-S-TiO2/TiO2 nanotube electrodes were prepared combined anodization and ultrasonic. • The photoelectrocatalytic properties of photoanodes were investigated in detail. • The enhanced visible light photocatalytic mechanism was proposed. -- Abstract: In the present work, N, S codoped TiO2 nano-crystallites (NCs) decorated TiO2 nano-tube arrays (N-S-TiO2 NCs/TNTAs) photoelectrodes have been successfully constructed through anodization method, followed by evaporation induced self-assembly (EISA) strategy. The structures of N-S-TiO2 NCs/TNTAs samples were characterized by scanning electrons microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron microscopy (XPS). Results indicated that TNTAs was partly covered by N, S codoped TiO2 NCs. Meanwhile, N elements coexisted in the forms of substitutional N (Ti–N and N–Ti–O) and interstitial N (Ti–O–N) in TiO2, while S elements were also incorporated into the lattice of TiO2 through substituting titanium atom and coexisted in the cationic forms of S6+ and S4+. In addition, optical and photoelectrochemical (PECH) properties of the as-prepared N-S-TiO2 NCs/TNTAs samples were investigated through UV–vis light diffuse reflection spectroscopy (DRS), transient open circuit potential (OCP), photocurrent response (PCR) and electro-chemical impedance spectroscopy (EIS). Furthermore, photodecomposition performances were evaluated by the yield of ·OH radicals and photocatalytic (PC) degradation of methyl blue (MB) under Xenon lamp irradiation. All results showed that N-S-TiO2 NCs/TNTAs photoelectrode exhibited intense visible light absorption ranging from 400 to 700 nm, high transient photoinduced current of 0.115 mA cm−2, open circuit photovoltage of −0.312 mV cm−2, generation of hydroxyl radicals and PC efficiency of 59.7% for the degradation of MB. The enhanced PC performance could mainly be attributed to the decoration of N, S codoped TiO2 NCs, which could not only enhance the light

  14. Preparation of CdS NCs decorated TiO2 nano-tubes arrays photoelectrode and its enhanced photoelectrocatalytic performance and mechanism

    International Nuclear Information System (INIS)

    CdS nano-crystallites decorated TiO2 nano-tubes arrays (CdS NCs/TiO2 NTAs) photoelectrodes were prepared through anodization, followed by electrodeposition strategy. Subsequently, structures of the resulting CdS NCs/TiO2 NTAs samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). In addition, the light absorption capacities and photoelectrochemical (PECH) properties were investigated through UV–visible diffuse reflectance spectrum (DRS), photocurrent response (PCR) and open-circuit photovoltage (OCP). Furthermore, photodecomposition performances were evaluated by the yield of ·OH radicals and photoelectrocatalytic (PEC) degradation of rhodamine B (RhB) under Xenon light irradiation. Moreover, the enhanced PC mechanism was proposed and confirmed through photoluminescence (PL) spectra and contribution of different reactive species. Results showed that hexagonal CdS NCs with uniform spherical sizes of 20 nm were successfully deposited onto the surface of highly ordered TiO2 NTAs, which could not only red-shift the light absorption to visible region between 400 and 700 nm, but also significantly enhance the generation of ·OH radicals. Furthermore, CdS NCs/TiO2 NTAs photoelectrodes possessed higher transient photogenerated current of 9.62 mA cm−2 and open-circuit photovoltage of −0.253 V cm−2 than that of bare TiO2 NTAs. Moreover, when external potential (−2 V) was applied, CdS NCs/TiO2 TNTAs samples performed higher PEC efficiency of 91.6%, which could be attributed to the intense light harvesting in visible region and high mobility and separation efficiency of photogenerated charge carriers

  15. Crack characterization for in-service inspection planning

    International Nuclear Information System (INIS)

    During in-service inspection by non destructive testing the reliability is highly dependent on how the equipment is adjusted to the specific object and to the anticipated crack feature.The crack feature and morphology vary widely between different cracking mechanisms and between material types in which the cracks appear. The major objective of this study was to characterize a number of morphology parameters for common crack mechanism and structure material combinations. Critical morphology parameters are crack orientation, shape, width, surface roughness and branching. The crack parameters were evaluated from failure analyses reported from the nuclear and non-nuclear industry. In addition, a literature review was carried out on crack parameter reports and on failure analysis reports, which were further evaluated. The evaluated crack parameters were plotted and statistically processed in data groups with respect to crack mechanism and material type. The fatigue crack mechanism were classified as mechanical, thermal or corrosion fatigue and stress corrosion crack mechanism as intergranular, transgranular or inter dendritic stress corrosion cracking. Furthermore, some common weld defects were characterized for comparison. The materials were divided into three broad groups, ferritic low alloy steels, stainless steels and nickel base alloys. The results indicate significant differences between crack parameters when comparing data from different crack mechanism/material type combinations. Typical parameter values and scatter were derived for several combinations where the data was sufficient for statistical significance. 10 refs, 105 figs, 14 tabs

    The small molecule component of chromoprotein enediyne antitumor antibiotics is biosynthesized through a convergent route, incorporating amino acid, polyketide, and carbohydrate building blocks around a central enediyne hydrocarbon core. The naphthoic acid moiety of the enediyne neocarzinostatin plays key roles in the biological activity of the natural product by interacting with both the carrier protein and duplex DNA at the site of action. We have previously described the in vitro characterization of an S-adenosylmethionine-dependent O-methyltransferase (NcsB1) in the neocarzinostatin biosynthetic pathway [Luo, Y., Lin, S., Zhang, J., Cooke, H. A., Bruner, S. D., and Shen, B. (2008) J. Biol. Chem. 283, 14694-14702]. Here we provide a structural basis for NcsB1 activity, illustrating that the enzyme shares an overall architecture with a large family of S-adenosylmethionine-dependent proteins. In addition, NcsB1 represents the first enzyme to be structurally characterized in the biosynthetic pathway of neocarzinostatin. By cocrystallizing the enzyme with various combinations of the cofactor and substrate analogues, details of the active site structure have been established. Changes in subdomain orientation were observed via comparison of structures in the presence and absence of substrate, suggesting that reorientation of the enzyme is involved in binding of the substrate. In addition, residues important for substrate discrimination were predicted and probed through site-directed mutagenesis and in vitro biochemical characterization.

  6. Characterization of serrated yielding in service exposed Inconel 625 alloy

    International Nuclear Information System (INIS)

    The Alloy-625 is an austentic alloy which is being used for a variety of components in the aerospace, marine, chemical and nuclear industries. Tensile tests have been carried out on service exposed Inconel 625 ammonia cracker tube used at heavy water production plant to study the effect of microstructure on the mechanical properties of the material. Owing to temperature gradient during in service condition the microstructure was different in top (T), middle (M) and bottom (B) sections of the tube. The stress-strain curve obtained from conventional tensile test was found to exhibit serrated yielding with in an intermediate temperature regime of 250-600 °C. Both normal and inverse Portevin-Le Chatelier (PLC) effect could be identified at lower and higher temperature regime respectively. The normal behavior was associated with type (A+B) serrations and interstitial atom C was held responsible for the aging of dislocations in this region. On the contrary, the serrations were of type C in nature in inverse PLC regime and were attributed to the locking of dislocations by substitutional Mo atoms. Further analyses of activation energy and transition temperature for normal to inverse PLC dynamics, supported with Transmission Electron Microscopy (TEM) observation revealed that the basic deformation mechanism was different in M and B samples than that in the T samples. While the deformation in T samples were achieved by usual dislocation migration, in M and B samples it was through the propagation of stacking faults in large γ” precipitates. The transition temperature from normal to inverse PLC dynamics also varied appreciably in T samples than that of the M and B ones which could be explained in terms of the delayed depletion of Mo solutes in solution for T samples.

    International Nuclear Information System (INIS)

    Before the decommissioning of the TRIGA HD II reactor of the 'Deutsches Krebsforschungszentrum' in Heidelberg (DKFZ) the spent nuclear fuel (126 TRIGA- F/A) had to be discharged from the reactor and shipped in 2001 to the United States. The Consortium NCS/GNS together with the DKFZ carried out this task including the following essential details: Implementation of structural measures inside the reactor building. Development and fabrication of loading units for the FIA. Development and fabrication of a transfer system for the loading units. Obtaining new German and US certifications for the casks. Loading of the casks. Shipment of the casks from DKFZ to the United States by road and sea. The successful completion of this task once again proved the operational experience of the Consortium NCS/GNS which will be useful for further worldwide shipments of spent nuclear fuel from research reactors. e.g. shipments from Europe, South America and Australia to the United States and France.

  8. The NCS 45 cask family: an updated design replaces an old design. Lessons learned during design, testing and licensing

    International Nuclear Information System (INIS)

    The NCS 45 cask family is intended to replace the cask types R52, TN6/1 and TN6/3. These packagings - country of origin France - were in operation worldwide since mid 1970. In the late nineties prolongations of the certificates of package approval became more and more difficult and time consuming. Finally only special arrangements for restricted contents were issued by the competent French authority which caused considerable problems when validations in other countries were applied for. To guarantee the availability of such a cask in the future for its customers NCS decided to replace the old casks by an updated design, the NCS 45 cask family

  9. Dosimetry study comparing NCS report-2 versus IAEA TRS-398 protocol for high energy photon beams

    International Nuclear Information System (INIS)

    In this work a dosimetry study is presented in which the results of absorbed dose determined at reference condition according to the IAEA TRS-398 protocol and the NCS report-2 are compared. The IAEA TRS-398 protocol for absorbed dose calibration is based on ionization chamber having absorbed dose to water calibration factor Ndw, while the NCS-2 dosimetry report for absorbed dose calibration is based on an ionization chamber having air- kerma calibration factor Nk. This study shows that the absorbed dose which is calculated with The IAEA TRS-398 formalisms is higher than that calculated with NCS report-2 formalisms within range from 0.4 to 0.9% in cobalt-60 beam as sensed by different ionization chambers, and from 0.2 to 1.1% for different higher energy photon beams of 6, 8 and 18 MV. The chambers used are PTW 30001, 30004, and NE-2571; which have calibration factors Nk and Ndw traceable to the BIPM (Bureau International des Poids et Mesures)

    Full Text Available Modulation of G protein-coupled receptor (GPCR signalling by local changes in intracellular calcium concentration is an established function of Calmodulin which is known to interact with many GPCRs. Less is known about the functional role of the closely related neuronal EF-hand Ca2+-sensor proteins that frequently associate with calmodulin targets with different functional outcome. In the present study we aimed to investigate if a target of calmodulin – the A2A adenosine receptor, is able to associate with two other neuronal calcium binding proteins, namely NCS-1 and caldendrin. Using bioluminescence resonance energy transfer and co-immunoprecipitation experiments we show the existence of A2A - NCS-1 complexes in living cells whereas caldendrin did not associate with A2A receptors under the conditions tested. Interestingly, NCS-1 binding modulated downstream A2A receptor intracellular signalling in a Ca2+-dependent manner. Taken together this study provides further evidence that neuronal Ca2+-sensor proteins play an important role in modulation of GPCR signalling.

  15. University of New Mexico short course in nuclear criticality safety: Training for new NCS [nuclear criticality safety] specialists

    International Nuclear Information System (INIS)

    Since 1973, the University of New Mexico (UNM) has given ten short courses in nuclear criticality safety (NCS). Generally, thee have been given every other year, although in 1989 it was decided to offer the course on an annual basis. This decision was primarily based on the large demand for NCS specialists and a large turnover rate in the industry. The purpose of the course is to provide a 1-week overview of NCS. The typical student has been involved in NCS for <1 yr, although it many cases they have been associated with the nuclear industry in other capacities for many years. The short course is conducted at several levels. Carefully prepared lectures provide the information framework for selected topics. The following topics are covered in the course: basic reactor theory, criticality accidents and consequences, hand calculations, administration of a criticality safety program, regulators and their processes, computer methods and applications, experimental methods and correlations, overview of some process operations, and transportation and storage issues in NCS

    A novel hexa aza cage, N(1)-(4-isothiocyanatobenzyl)-3,6,10,13,16,19-hexaazabicyclo[6.6.6]icosane-1,8-diamine (SarAr-NCS) was synthesized in good yield and characterized by (1)H NMR and electrospray mass spectrometry. A new method for the synthesis of the related N(1)-(4-carboxybenzyl)-3,6,10,13,16,19-hexaazabicyclo[6.6.6]icosane-1,8-diamine (AmBaSar) using the p-carboxybenzaldehyde is reported. The complexation of Cu(2+), Co(2+) and Zn(2+) by the two ligands over a range of pHs was found to be similar to the parent derivative SarAr. SarAr-NCS was conjugated to both silica particles (≈90 nm diam.) and the model B72.3 murine antibody. The SarAr-NCSN-silica particles were radiolabeled with Cu(2+) doped (64)Cu and the number of ligands conjugated was calculated to be an average of 7020 ligands per particle. Conjugation of SarAr-NCS to the B72.3 antibody was optimized over a range of conditions. The SarAr-NCSN-B72.3 conjugate was stored in buffer and as a lyophilized powder at 4 °C over 38 days. Its radiolabeling efficiency, stability and immunoreactivity were maintained. The development of a high yielding synthesis of SarAr-NCS should provide an entry point for a wide range of Cu and Zn radiometal PET imaging agents and potentially radiotherapeutic agents with (67)Cu.

  18. Experiences with the characterization of new and ex-service grade 91 material

    Martensitic Grade 91 steel is intensively used for tubes and pipes as a replacement for Grade 22 and in the new ultra super critical power plants for components subject to temperatures up to 600 C. This relatively new material is more complex than its predecessors, as its high temperature strength depends on the precise distribution of fine precipitates. Hence small deviations in composition or heat treatment can have a significant influence on, for example, the creep strength. As the amount of available data on ex-service components in Grade 91 is still limited, a characterization of two ex-service materials and a comparison with new material was carried out. The chemical composition, microstructure, creep strength, mechanical properties and hardness of two new tubes, one new pipe, one ex-service tube and one ex-service pipe in Grade 91 were determined. For the determination of the creep strength the stress relaxation testing technique was used and compared with conventional creep tests on the same material. Stress relaxation testing proved to be an adequate technique to determine the current creep strength of Grade 91 material. A strong dependency of small deviations in composition on the creep strength was noted. A low carbon content seemed to decrease the creep strength significantly. The distribution of the precipitates was investigated with TEM for one new and one ex-service tube. The ex-service tube did show a slight coarsening of the M{sub 23}C{sub 6} compared to the new tube. However, the overall amount of precipitates (fine MX and M{sub 23}C{sub 6}) was larger for the ex-service tube, which had a higher amount of carbon. This could explain the higher creep strength of this tube. (orig.)

    In this data article we show the specificity of the Ca(2+)-induced mobility shift in three proteins that belong to the neuronal calcium sensor (NCS) protein family: Hippocalcin, GCAP1 and GCAP2. These proteins did not display a shift in mobility in native gels when incubated with divalent cations other than Ca(2+) - such as Mg(2+), Ba(2+), and Sr(2+), even at 10× concentrations. The data is similar to that obtained with another NCS protein, neurocalcin delta (Viviano et al., 2016, "Electrophoretic Mobility Shift in Native Gels Indicates Calcium-dependent Structural Changes of Neuronal Calcium Sensor Proteins", [1]).

    Detection of mercapto-containing pesticides plays a crucial role in food and water safety. A new Re(I)-NCS-Pt(II) complex, [Re(4,4'-di-tert-butyl-2,2'-bipyridine)(CO)3(NCS)]-[Pt(DMSO)(Cl)2] (1), was synthesized and characterized. The synthetic procedure, characterization results, and photophysical data for 1 are reported in this paper. Solvated complex 1 demonstrated luminescent chemodosimetric selectivity for phorate, demeton, and aldicarb (three common mercapto-containing pesticides) with method detection limits (MDLs) of 1.00, 2.87, and 2.08 ppm, respectively. The binding constants (log K) of 1 toward them were in the 3.24-3.44 range. The analyte selectivity of the complex was found to be dependent on the bridging linkage (C≡N and N═C═S) between the Re(I) and Pt(II) centers. The solid-supported dosimetric device 1 was fabricated by blending complex 1 with Al2O3 and poly(vinyl chloride) (PVC) powder. The MDLs of the device toward the mercapto-containing pesticides were 0.48-0.60 ppm. The device was applicable to pesticides in real water bodies such as taps, rivers, lakes, and underground water bodies with excellent recoveries and relative standard deviations of 76.2-108.0% and 2.9-6.7%, respectively. Its spectrofluorimetric changes could be analyzed by naked eye within 20 min with a linear luminometric response toward increases in the phorate concentration (0-8.0 ppm) with R = 0.999.

  2. Characterizing learning-through-service students in engineering by gender and academic year

    Science.gov (United States)

    Carberry, Adam Robert

    Service is increasingly being viewed as an integral part of education nationwide. Service-based courses and programs are growing in popularity as opportunities for students to learn and experience their discipline. Widespread adoption of learning-through-service (LTS) in engineering is stymied by a lack of a body of rigorous research supporting the effectiveness of these experiences. In this study, I examine learning-through-service through a nationwide survey of engineering undergraduate and graduate students participating in a variety of LTS experiences. Students (N = 322) participating in some form of service -- service-learning courses or extra-curricular service programs -- from eighty-seven different institutions across the United States completed a survey measuring demographic information (institution, gender, academic year, age, major, and grade point average), self-perceived sources of learning (service and traditional coursework), engineering epistemological beliefs, personality traits, and self-concepts (self-efficacy, motivation, expectancy, and anxiety) toward engineering design. Responses to the survey were used to characterize engineering LTS students and identify differences in these variables in terms of gender and academic year. The overall findings were that LTS students perceived their service experience to be a beneficial source for learning professional skills and, to a lesser degree, technical skills, held moderately sophisticated engineering epistemological beliefs, and were generally outgoing, compassionate, and adventurous. Self-perceived sources of learning, epistemological beliefs, and personality traits were shown to be poor predictors of student engineering achievement. Self-efficacy, motivation, and outcome expectancy toward engineering design were generally high for all LTS students; most possessed rather low anxiety levels toward engineering design. These trends were generally consistent between genders and across the five academic

    Full Text Available The purpose of this study was to determine the elemental composition of three types of waste from tempeh production. They are soybean hull “tempeh waste” after dehulling soybeans, tempeh wastewater after soaking dehulled soybeans in water for 24 h, and tempeh wastewater after boiling dehulled soybeans in water for 30 min. By using ED-XRF analyzer, it was revealed that tempeh waste contained Mg, Si, P, S, K, Ca, Mn, Fe, and Zn. The highest elemental content was K, followed by Ca, P, and Mg. NCS analysis showed that tempeh waste was composed of C, N, and S with C/N ratio of 11.20. The present study provides evidence that both tempeh waste and wastewater are rich in carbon and nutrient contents, thus their potential for both inorganic and organic nutrient and carbon sources for microbial growth in bioremediation or as natural NPK fertilizers is promising.

    International Nuclear Information System (INIS)

    The modeling and simulation of nuclear power plant control system has been investigated. Some mathematical models for rapid and accurate simulation are derived, including core models, pressurizer model, steam generator model, etc. Several numerical methods such as Runge-Kutta Method and Treanor Method are adopted to solve the above system models. In order to model the control system conveniently, a block diagram-oriented visual modeling platform is designed. And the Discrete Similarity Method is used to calculate the control system models. A corresponding simulating software, NCS, is developed for researching on the control systems of commercial nuclear power plant. And some satisfactory results are obtained. The research works will be of referential and applying value to design and analysis of nuclear power plant control system

  6. Effect of salts, solvents and buffer on miRNA detection using DNA silver nanocluster (DNA/AgNCs) probes

    International Nuclear Information System (INIS)

    MicroRNAs (miRNAs) are small regulatory RNAs (size ∼21 nt to ∼25 nt) which regulate a variety of important cellular events in plants, animals and single cell eukaryotes. Especially because of their use in diagnostics of human diseases, efforts have been directed towards the invention of a rapid, simple and sequence selective detection method for miRNAs. Recently, we reported an innovative method for the determination of miRNA levels using the red fluorescent properties of DNA/silver nanoclusters (DNA/AgNCs). Our method is based on monitoring the emission drop of a DNA/AgNCs probe in the presence of its specific target miRNA. Accordingly, the accuracy and efficiency of the method relies on the sensitivity of hybridization between the probe and target. To gain specific and robust hybridization between probe and target, we investigated a range of diverse salts, organic solvents, and buffer to optimize target sensing conditions. Under the newly adjusted conditions, the target sensitivity and the formation of emissive DNA/AgNCs probes were significantly improved. Also, fortification of the Tris–acetate buffer with inorganic salts or organic solvents improved the sensitivity of the DNA/AgNC probes. On the basis of these optimizations, the versatility of the DNA/AgNCs-based miRNA detection method can be expanded. (paper)

    Prosthesis interface is one of the most important components to promote individual׳s health and comfort, as it establishes direct contact with the skin and transfers loads generated during gait. The aim of this study was to mechanically characterize, three commercial interfaces (block copolymer, silicone gel and silicone elestomer), under static and dynamic conditions, before and after undergoing a process of chemical aging in synthetic sweat for periods up to 90 days. Static mechanical compression tests were performed on the materials, as well as fatigue tests to assess their static and dynamic mechanical behaviors, respectively. For the second, a sinusoidal load was applied with an appropriate range of deformation for each material. Several analytical techniques were also used to characterize the materials, namely Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), and morphology characterization by Scanning Electron Microscopy (SEM). All the tested materials have strong viscoelastic behavior, showing a linear response for small deformations, followed by a nonlinear behavior for higher deformation. The block copolymer and the silicone gel are affected by aging in synthetic sweat in a similar way, with a significant increase of their rigidity after 30 days, followed by a progressive reduction. The silicone elastomer displays a continuous increase of rigidity along the 90 days of storage, being the most sensitive to aging affects. It also exhibits the lowest stiffness value, being suitable for uses that require maximum comfort. All materials demonstrate chemical and structural stability under service simulated conditions.

    Magnetic interactions J in [Cr(isoq)2(NCS)4]--based charge-transfer salts, (BDH-TTP)[Cr(isoq)2(NCS)4], (TMTTF)[Cr(isoq)2(NCS)4], and (BO)[Cr(isoq)2(NCS)4], are estimated on the basis of the extended Hückel molecular orbital calculations (BDH-TTP = 2,5-bis(1,3-dithiolan-2-ylidene)-1,3,4,6-tetrathiapentalene, BO = bis(ethylenedioxy)-tetrathiafulvalene, TMTTF = tetramethyltetrathiafulvalene, and isoq = isoquinoline). From this, experimental magnetic properties are discussed, and the magnetic structures are determined. (BDH-TTP)[Cr(isoq)2(NCS)4] is composed of two-dimensional array of antiferromagnetically coupled ferrimagnetic chains. These two-dimensional arrays, however, have net magnetic moment perpendicular to the sheets and give rise to weak ferromagnetism. (TMTTF)[Cr(isoq)2(NCS)4] and (BO)[Cr(isoq)2(NCS)4] have similar “body-centered” molecular arrangement. The TMTTF salt has considerable πd-interaction in two directions, and this compound actually shows a magnetic transition. The BO salt has large πd-interaction only in one direction, but the frustrating dd- and ππ-interactions are considerably large. Consequently, this compound does not exhibit a magnetic transition.

    Nanoparticles of calcium sulfate (nCS) have potential advantages as a ceramic matrix, scaffold and/or vehicle for delivering growth factors for osseous regeneration in a variety of clinical situations. The objectives of this study were to synthesize and characterize nanoparticles of hemihydrate calcium sulfate (nCS) and to develop a nCS-based system for bone regeneration. A cryo-vacuum method was used to process dihydrate CS into dihydrate nCS, which was then subjected to oven drying to produce hemihydrate. The nCS was sterilized by glow discharge treatment for use as a synthetic graft material for the treatment of bone defects. Electron microscopy showed that the nCS powder consisted of aggregates of closely arranged acicular crystals, approximately 30-80 nm in width, 400-600 nm in length and approximately 80-100 nm in diameter, providing a surface area about ten times that of conventional CS. Thorough physico-chemical characterization confirmed the composition and phase of the material. Cell viability/metabolic activity assays and alkaline phosphate assays confirmed the safety and biocompatibility of nCS. Release kinetics for adsorbed platelet-derived growth factor and bone morphogenetic protein-2 (BMP-2) suggests that nCS may serve as an appropriate vehicle for slow release delivery of these agents. The studies presented here give evidence of the advantages of nCS as a scaffold to support osteoblastic cell activity.

    Safe disposal of food waste is becoming an impending issue in China with the rapid increase of its production and the promotion of environmental awareness. Food waste from catering services in Hangzhou, China, was surveyed and characterized in this study. A questionnaire survey involving 632 units across the urban districts showed that 83.5% of the food waste was not properly treated. Daily food waste production from catering units was estimated to be 1184.5 tonnes. The ratio of volatile solid to total solid, easily biodegradable matter (including crude fat, crude protein and total starch) content in total solid and the ratio of total organic carbon to nitrogen varied in ranges of 90.1%-93.9%, 60.9%-72.1%, and 11.9-19.9, respectively. Based on the methane yield of 350 mL g VS(-1) in anaerobic batch tests, annual biogas energy of 1.0 × 10(9) MJ was estimated to be recovered from the food waste. Food waste from catering services was suggested to be an attractive clean energy source by anaerobic digestion. PMID:24980033

    Freshwater ecosystems and the services they provide are under increasing anthropogenic pressure at local (e.g., irrigation diversions, wastewater discharge) and global scales (e.g., climate change, global trading). The impact depends on an ecosystem's sensitivity, which is determined by its geophysical and ecological settings, and the population and activities in its surrounding watershed. Given the importance of ecosystem services, it is critical that we improve our ability to identify and understand changes in aquatic ecosystems, and translate them to risk of service loss. Furthermore, to inspire changes in human behavior, it is equally critical that we learn to communicate risk, and pose risk mitigation strategies, in a manner acceptable to a broad spectrum of stakeholders. Quantifying the nature and timing of the risk is difficult because (1) we often fail to understand the connection between anthropogenic pressures and the timing and extent of ecosystem changes; and (2) the concept of risk is inherently coupled to human perception, which generally differs with cultural and socio-economic conditions. In this study, we endeavor to assess aquatic ecosystem risks across an international array of six study sites. The challenge is to construct a methodology capable of capturing the marked biogeographical, socioeconomic, and cultural differences among the sites, which include: (1) Muskoka River watershed in humid continental Ontario, Canada; (2) Lower San Joaquin River, an impounded snow-fed river in semi-arid Central California; (3) Ciénaga Grande de Santa Marta, a tropical coastal lagoon in Colombia; (4) Senguer River basin in the semi-arid part of Argentina; (5) Laguna de Rocha watershed in humid subtropical Uruguay; and (6) Palomas Lake complex in oceanic Chilean Patagonia. Results will include a characterization of the experimental gradient over the six sites, an overview of the risk assessment methodology, and preliminary findings for several of the sites.

    Surfactant-free nanocrystals of the model spin-crossover compound [Fe(phen)2(NCS)2] (phen: 1,10-phenanthroline) have been synthesized applying the reverse micelle technique. The morphology of the nanocrystals, characterized by scanning electronic microscopy, corresponds to rhombohedric platelets with dimensions ranging from 203 × 203 × 106 nm to 142 × 142 × 74 nm. Variation of the concentration of the Fe(BF4)2·6H2O salt in the synthesis has been found to have little influence on the crystallite size. In contrast, the solvent-surfactant ratio (ω) is critical for a good particle growth. The spin transition of the nanocrystals has been characterized by magnetic susceptibility measurements and Mössbauer spectroscopy. The nanocrystals undergo an abrupt and more cooperative spin transition in comparison with the bulk compound. The spin transition is centered in the interval of temperature of 175-185 K and is accompanied by 8 K of thermal hysteresis width. The crystallite quality more than the crystallite size is responsible for the higher cooperativity. The magnetic properties of the nanocrystals embedded in organic polymers such as polyethylene glycol, nujol, glycerol, and triton have been studied as well. The spin transition in the nanocrystals is affected by the polymer coating. The abrupt and first-order spin transition transforms into a more continuous spin transition as a result of the chemical pressure asserted by the organic polymers on the Fe(II) centers.

It crystallizes in the orthorhombic system, space group Pbca with a = 16.8725(13), b = 19.0046(15), c = 20.0583(16) (A), Z = 8, V = 6431.8(9) (A)3, C33H32N6Ni2O4S1, Mr= 726.13, Dc = 1.500 g/cm3, F(000) = 3008, μ = 1.284 mm-1, the final R = 0.0394 and wR = 0.0767 for 4449 observed reflections with Ⅰ>2σ(Ⅰ). The complex involves a N,N'-ethylene-bis(salicylaldiminato) Schiff base, an isothiocyanato anion and an ammonium cation. The nickle(Ⅱ) ion adopts a distorted square coordination geometry with N2O2 set of Schiff base ligand. The complexes are linked into a dimmer via intermolecular hydrogen bonds and the [Ni(salen)] moieties are connected together to form a 2-D layer structure by intermolecular N-H…O hydrogen bonds and π-π stacking. Cyclic-voltammetry method was used to characterize electrochemically the complex.

  20. Letter of Intent for River Protection Project (RPP) Characterization Program: Process Engineering and Hanford Analytical Services and Characterization Project Operations and Quality Assurance

    International Nuclear Information System (INIS)

    The Characterization Project level of success achieved by the River Protection Project (RPP) is determined by the effectiveness of several organizations across RPP working together. The requirements, expectations, interrelationships, and performance criteria for each of these organizations were examined in order to understand the performances necessary to achieve characterization objectives. This Letter of Intent documents the results of the above examination. It formalizes the details of interfaces, working agreements, and requirements for obtaining and transferring tank waste samples from the Tank Farm System (RPP Process Engineering, Characterization Project Operations, and RPP Quality Assurance) to the characterization laboratory complex (222-S Laboratory, Waste Sampling and Characterization Facility, and the Hanford Analytical Service Program) and for the laboratory complex analysis and reporting of analytical results

    We report on the size reduction of the neutral Fe(phen)2(NCS)2 prototypical compound exhibiting a cooperative spin-crossover associated with a first-order phase transition (at ca. 176 K). We use the [Fe(phen)3](NCS)2 ionic precursor and the solvent-assisted precipitation technique to prepare an array of crystalline objects with sizes varying over two orders of magnitude (from 15 up to 1400 nm). TEM, X-ray diffraction and IR measurements provide evidences for the formation of particles of neutral and ionic species, which results from the interplay between the relevant chemical equilibrium and the reaction kinetics (ligand extraction, complex precipitation), and the modulation of the latter by physico-chemical parameters. A thermal transformation of diamagnetic nanocrystals of [Fe(phen)3](NCS)2 leads to spin-crossover particles of Fe(phen)2(NCS)2 of a comparable size. Powders of nano-, micro- and polycrystals of Fe(phen)2(NCS)2 present X-ray diffractograms typical of the so-called polymorph II. The importance of size effects on the cooperative spin-crossover process was probed with magnetic, Mössbauer, Raman and IR spectroscopic measurements. Each sample exhibits spin-state switching of the Fe(ii) ions. The salient features are: a cooperativity preserved at the micrometric scale, a very limited downshift of the transition temperature and an asymmetric spreading of the thermal process (over ca. 100 K) with the size reduction. At temperatures close to room temperature, the process appears to be quasi complete whatever the size of the samples. This result, extracted from Raman data, was confirmed by Mössbauer measurements in the case of the largest objects (LS residue <5-10% for bulk and microparticles). Below 150 K, a very efficient low-spin to high-spin photoexcitation was induced by the Raman laser beam in all the samples which prevents the extraction of the high-spin fraction in this temperature range. However variable temperature IR spectra of the 29 nm particles

    One mononuclear cobalt(II) compound of the type [Co(bnzd)2(NCS)2(OH2)2] (1) (bnzd = benzidine) has been isolated through a single-pot reaction of the molecular building components in MeOH-H2O solvent mixture at room temperature and characterized by physico-chemical and spectroscopic methods. The crystal structure of complex 1 has an octahedral geometry with trans, trans, trans orientations in the order (Na,Na), (Nt,Nt), (Ow,Ow) [Na = N(amine), Nt = N(thiocyanate) and Ow = O(water)]. In crystalline state, individual units of 1 are associated by weak cooperative O-H…N, O-H…S and N-H…S hydrogen bonds resulting in a 3D network structure. The compound is redox active and shows luminescence in MeOH solution. Thermal decomposition pattern of 1 reveals the presence of two coordinated water molecules. Variabletemperature magnetic susceptibility measurement shows significant orbital contribution and numerical matrix diagonalization method gives the best fit parameters: = A∗k = 1.43; = −130 cm-1; = −864 cm-1; TIP = 0.000975; R = 1.19 × 10−4.

    The synthesis, crystal structure, electrochemical and magnetic properties of a type of pyridine-modulated linear pentanuclear complex, [Ni5(μ-dmpzda)4(NCS)2] [dmpzda-H2=N,N'-di(4-methyl pyridin-2-yl)pyrazine-2,6-diamine], were studied. The complex involves a Ni5 linear chain unit with all of the Ni-Ni-Ni being nearly 180°, terminated by the two axial ligands. This pentanuclear linear metal chain is helically wrapped by four syn-syn-syn-syn type dmpzda ligands. There are two types of Ni-Ni distances existing in the complex. The terminal Ni-Ni distances bonded with the axial iigand are longer (2.3821 A) affected by the axial ligands. The inner Ni-Ni distances are very short and remain constant (2.2959 A). Two terminal Ni(Ⅱ) ions bonded with the axial ligands are in a square-pyramidal (NiN4NCS) environment and exhibit long Ni-N bonds (2.103 A), which are consistent with a high-spin Ni(Ⅱ) configuration. The inner three Ni(Ⅱ) ions display short Ni-N (1.886-1.906 A) bond distances, which are consistent with a squareplanar (NiN4), diamagnetic arrangement of a low-spin Ni(Ⅱ) configuration. This compound exhibits similar [Ni5(μ-tpda)4(NCS)2] magnetic behavior, indicating an anfiferromagnetic interaction of two terminal high-spin Ni(Ⅱ) ions in these complexes.

    The Usumacinta basin is characterized by aboundance of natural and scenic resources. It also houses a vast biodiversity (wich also means invaluable genetic resources). Its river is the longest in Mexico (main channel length of 927 km). Therefore it is one of the most productive regions of the country in terms of ecosystem services (such as habitat for biodiversity, maintenance of wetlands, water flows generation, carbon sequestration, soil retention, etc.) that are directly related to the hydrological functioning. During the last centuries, human activities on the Usumacinta basin have drastically changed its geomorphology and vegetation cover. As a result the hydrological cycle has been greatly modified. Therefore, it is necessary to conduct studies in order to support planning activities and implementation of public policies, as well as, to generate a permanent scientific ecosystem monitoring system. This paper presents the results of a study focused on estimating the water balance of this frontier basin. Satellite and field data is used. Variables as vegetation cover (generated by classification of Landsat and MODIS), digital terrain model (SRTM), surface temperature (MODIS), potential evaporation, precipitation and runoff measurements were processed. Various techniques of Remote Sensing, geospatial models (as SSEB and the model for definition of surface hydrological connectivity) and spatial analysis (geostatistics and map algebra) were implemented. The results were integrated into the environment of a Geographic Information System. These are estimates of actual evapotranspiration, soil moisture and runoff, among other biophysical parameters. For the lower part of the basin a balance was performed to estimate inputs of water from runoff and precipitation to the large amount of wetlands in the area. Additionally, areas generating runoff and areas in which most of the precipitaion infiltrates were also mapped. The geo-information obtained is requiered for

    Amorphous SiHfBCN ceramics were prepared from a commercial polysilazane (HTT 1800, AZ-EM), which was modified upon reactions with Hf(NEt2)4 and BH3·SMe2, and subsequently cross-linked and pyrolyzed. The prepared materials were investigated with respect to their chemical and phase composition, by means of spectroscopy techniques (Fourier transform infrared (FTIR), Raman, magic-angle spinning nuclear magnetic resonance (MAS NMR)), as well as X-ray diffraction (XRD) and transmission electron microscopy (TEM). Annealing experiments of the SiHfBCN samples in an inert gas atmosphere (Ar, N2) at temperatures in the range of 1300-1700 °C showed the conversion of the amorphous materials into nanostructured UHTC-NCs. Depending on the annealing atmosphere, HfC/HfB2/SiC (annealing in argon) and HfN/Si3N4/SiBCN (annealing in nitrogen) nanocomposites were obtained. The results emphasize that the conversion of the single-phase SiHfBCN into UHTC-NCs is thermodynamically controlled, thus allowing for a knowledge-based preparative path toward nanostructured ultrahigh-temperature stable materials with adjusted compositions.

    Full Text Available This article characterizes the services providing care to victims in five Brazilian regions with high violence and accident rates. It analyzes care activities and strategies, the profile of the teams, the conditions of installations, equipment and supplies, integrated care and registration services and the opinion of health managers with respect to the needs and requirements for a better care to the victims. The sample is composed by 103 services: 34 from Recife, 25 from Rio de Janeiro, 18 from Manaus, 18 from Curitiba and 8 from Brasília. The still preliminary results indicate: lower number of services focusing on the elderly; scarce investment in preventive actions; the principal actions carried out are social assistance, ambulatory and hospital care and psychological assistance; patients received from Basic Health Units require attention of the communities and families; need for investment in capacity building programs for professionals; precarious registries, data handled manually. The wording of the National Policy for Reduction of Morbidity and Mortality from Accidents and Violence is not well-known and there is a lack of articulation among and inside sectors and between prehospital and emergency care services. Rehabilitation services are insufficient in all cities.

However, the use of DPDS in pharmacology is limited due to in vivo pro-oxidative effects. In addition, studies have shown that DPDS-loaded nanocapsules (DPDS-NCS have greater bioavailability than free DPDS in mice. Accordingly, the aim of this study was to investigate the antioxidant properties of DPDS-NCS in vitro and biological activity in mice. Our in vitro results suggested that DPDS-NCS significantly reduced the production of reactive oxygen species and Fe(II-induced lipid peroxidation (LPO in brain. The administration of DPDS-NCS did not result in death or change the levels of endogenous reduced or oxidized glutathione after 72 hours of exposure. Moreover, ex vivo assays demonstrated that DPDS-NCS significantly decreased the LPO and reactive oxygen species levels in the brain. In addition, the highest dose of DPDS-NCS significantly reduced Fe(II- and sodium nitroprusside-induced LPO in the brain and Fe(II-induced LPO in the liver. Also, δ-aminolevulinate acid dehydratase within the brain was inhibited only in the highest dose of DPDS-NCS. In conclusion, our data demonstrated that DPDS-NCS exhibited low toxicity in mice and have significant antioxidant characteristics, indicating that nanoencapsulation is a safer method of DPDS administration.

    Well-aligned densely-packed rutile TiO(2) nanocrystals (NCs) have been grown on sapphire (SA) (100) and (012) substrates via metal-organic chemical vapor deposition (MOCVD), using titanium-tetraisopropoxide (TTIP, Ti(OC(3)H(7))(4)) as a source reagent. The surface morphology as well as structural and spectroscopic properties of the as-deposited NCs were characterized using field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), selected-area electron diffractometry (SAED), x-ray diffraction (XRD) and micro-Raman spectroscopy. FESEM micrographs reveal that vertically aligned NCs were grown on SA(100), whereas the NCs on the SA(012) were grown with a tilt angle of ∼33° from the normal to substrates. TEM and SAED measurements showed that the TiO(2) NCs on SA(100) with square cross section have their long axis directed along the [001] direction. The XRD results reveal TiO(2) NCs with either (002) orientation on SA(100) substrate or (101) orientation on SA(012) substrate. A strong substrate effect on the alignment of the growth of TiO(2) NCs has been demonstrated and the probable mechanism for the formation of these NCs has been discussed. PMID:21817648

    Full Text Available Gas service station workers who work near volatile organic compounds (VOCs sources, such as gasoline vapor emissions, and motor vehicle exhausts, may be exposed to highly elevated VOCs levels. This study investigates air samples from gas service stations in Thailand to evaluate the health risks following inhalation exposure. Personal air samplings were obtained at nine gas service stations in Chonburi, Thailand from October to December 2007. The concentrations of benzene, toluene, ethylbenzene, xylenes, and hexane in the air from the workplaces were significantly higher than in a control group of office workers (p<0.05. However, all VOCs in these air samples were lower than TWA limit of Thailand and the OSHA standard. Samples of urine, collected after 8-h work periods which were analyzed for VOCs metabolites, including t,t muconic acid, hippuric acid, mandelic acid and m-hippuric acid, demonstrate that the average levels of metabolites in gas service station workers and in controls were close, except for t,t muconic acid of gas service station workers which displayed higher levels than the in the controls. The lifetime cancer and noncancer risks for the workers exposed to VOCs were also assessed. Results show that all nine gas service stations in this study had a elevated lifetime cancer risk ranging from 53 to 630 per million, thus exceeding the normal risk of 1 per million. For noncancer risks, the levels in all gas stations ranged between 0.03 and 0.4, which is well below the reference hazard level of 1.0. Benzene may the most important cause of both cancer and noncancer risk followed by 1,3 butadiene.

    Full Text Available Objectives: to characterize the clinical and sociodemographic profiles of women with breast cancer treated at the Oncology Unit of the Federico Lleras Acosta Hospital in Ibagué, Colombia between 2005 and 2009, and to identify service times. Methodology: a retrospective descriptive study in which 308 records were selected. Variables were collected using an instrument developed by the authors. The statistical analysis was conducted using the SPSS software. Results: the predominant age group was 45 to 64 years old. Additionally, 57.8% of these women were married. Similarly, most of them were from urban areas. The average age of menarche was 13 years. Half of the participants had been pregnant at least 3 times, and most of them were in the postmenopausal stage of their lives. The most frequent histological type was the infiltrating ductal one, as well as stage IIIB. The predominant surgical choices were modified radical mastectomy, pre- and post-operative chemotherapy, and postoperative radiotherapy. As for service times, there were delays in the admission to the oncology unit and treatment initiation. Conclusion: there was a low rate of carcinoma in situ and a high proportion of stage IV carcinoma in comparison to other studies from developed countries. The high rates of abandonment in post treatment follow-up, the shortcomings in case monitoring, and the findings concerning service times suggest the need for institutional corrective measures in order to improve the quality of the healthcare service in breast cancer patients.

  2. Panchromatic Ru (II) Dipyrrins as NCS Free Sensitizers Showing Highest Efficiency for DSSCs

    International Nuclear Information System (INIS)

    Two new Ru(II) complexes bearing with substituted dipyrrinato ligands (GS3 and GS10) have been successfully synthesized and characterized. These sensitizers exhibit panchromatic light harvesting properties, rendering them promising for DSSC applications. GS3 has shown high overall power conversion efficiency (η = 2.79%) compared to GS10 which is the highest so far in the case of Ru (II) dipyrrinato dyes. Density functional theory (DFT) and time-dependent DFT calculations were measured for GS3 and GS10 to understand their structural, electronic and photophysical properties

    Full Text Available This paper presents a user-centric and application-specific QoS assessment methodology for cellularcommunication networks. Specifically, it uses the Analytic Hierarchy Process (AHP to evaluate QoS as amulti-criteria decision problem that represents how well cellular networks’ data services are perceivedgiven particular sets of application classes and relative to other networks servicing in the same area. Aspart of the methodology, drive testing is performed to collect objective measurements associated withidentified QoS criteria for data services. Once drive testing is performed and data collected, multiplenetworks are compared to determine the network that provides higher QoS based on users’ perception ofquality. The selection of the best performing network is based on the output provided by the AHPapproach, which is used as unified measurement of the perceived QoS by users on different networks. Inorder to determine application-specific priorities, the approach presented uses three different applicationclasses, including Emergency, Business, and Personal. For each class, the relative importance of eachquality evaluation criteria is adjusted in the AHP procedure to reflect the priorities of the servicesexpected. Through several case studies, the approach is proven successful in providing a way foranalyzing user-centric QoS for application-specific scenarios.

  5. The spatial distribution of silicon NCs and erbium ion clusters by simultaneous high-resolution energy filtered and Z-contrast STEM and transmission electron tomography

    Imaging the spatial distribution of silicon nanocrystals (Si-NCs) and erbium ion clusters can assist in the development of light-emitting erbium-doped silicon nanocomposites. We applied simultaneous energy-filtered and high-angle annular dark field imaging in the scanning transmission electron microscopy (STEM) mode; the former method images the Si NCs and the latter is sensitive to the high atomic number of the Er{sup 3+} ions. Both methods were performed simultaneously so as to avoid relative image drift. In Er-doped Si nano-composites, we find that the Er ions are not uniformly distributed in the matrix: instead, they form clusters that appear in projection images to decorate the boundaries of the Si-NCs. This structure may develop during sample annealing, due to the low solubility of Er in the forming Si clusters. Although multi-detector simultaneous imaging is a good way to avoid nanometer-scale image drift that could otherwise conceal the nanoscale spatial relationship between Si-NCs and Er clusters, an additional difficulty relates to the projection imaging methods. Essentially, it is hard to obtain spatial information parallel to the electron beam direction, so where there is apparent overlap we cannot ascertain whether an Er cluster (for example) lies above, below, or inside a given Si-NC. Therefore, we also report on initial electron beam tomography investigations whose goal is ultimately to generate methods for obtaining the Er and Si cluster distribution in 3D. The results can lead to improved understanding of the sensitization mechanism and optimization for Er-doped silicon nanocomposites; the clustered nature of the Er ions near the Si NCs is certainly undesirable and may explain the typically short Er{sup 3+} photoluminescence (PL) lifetimes (compared to Er-doped silica) and the difficulty in reliably observing stimulated emission phenomena (copyright 2011 WILEY-VCH Verlag GmbH and Co.

    Full Text Available ABSTRACT Innovation is essential for improving organizational performance in both the private and public sectors. This article describes and analyzes the 323 innovation experiences of the Brazilian federal public service that received prizes during the 16 annual competitions (from 1995 to 2012 of the Award for Innovation in Federal Public Management held by the Brazilian National School of Public Administration (ENAP. It is a qualitative and quantitative study in which were employed as categories for analysis the four types of innovation defined in the Copenhagen Manual: product, process, organizational and communication. The survey results allow us to affirm that there is innovation in the public sector, in spite of the skepticism of some researchers and the incipient state of theoretical research on the subject. It was possible to observe that organizational innovation was the one with the highest number of award- -winning experience, followed respectively by process, communication and product innovation, with citizen services and improvement of work processes being the main highlights. The results showed that, although the high incidence of innovation occurs at the national level, a significant number of innovations also occur at the local level, probably because many organizations of the federal government have their actions spread only at this level of government. Concerning the innovative area, health and education predominate, with almost 33% of initiatives, which can be explained by capillarity of these areas and the fact that both maintain a strong interaction with the user. The contributions of this work include the use of theoretical model of innovation analysis in the public sector in Brazil still upcoming, and the systematization of knowledge in empirical basis for this innovation. In this sense, it also contributes to the development of the theory with the presentation of evidence that the characteristics, determinants and

  7. Further characterization of chinese hamster mutagen sensitive mutants using calicheamycin and neocarcinostatin

    International Nuclear Information System (INIS)

    To further characterize mutagen sensitive Chinese hamster V79 mutant cell lines two new radiomimetic agents i.e. calicheamycin (CAL) and neocarcinostatin (NCS) were used. Whereas X-rays produces a variety of non-specific lesions in the DNA, mainly single strand breaks (SSB), CAL induces only double strand breaks (DSB) at sequence specific sites (TCCT). NCS, on the other hand, causes SSB and to a much lesser extent apurinic sites at AGC sequences in the DNA. The obtained results demonstrate in most of the mutants and expected parallelism between X-ray sensitivity and sensitivity to the antitumor antibiotics CAL and NCS. Furthermore, enhanced sensitivities for chromosomal aberrations are overall and not due to specific types of aberrations. At present an explanation for the recorded chromosomal hypo-sensitivity of V-H1 cells for NCS awaits further experimentation. (authors)

    Civitillo, John M; Gheitasi, Amir; Saliba, Mark; Kassner, Bernard L

    2014-01-01

    The Hybrid Composite Beam (HCB) system is an innovative structural technology that has been recently used in bridge construction within the U.S. transportation network. In this system, the superstructure consists of a conventional reinforced concrete deck supported by Hybrid Composite Beams. Each beam is comprised of a glassfiber reinforced polymer (FRP) box shell containing a tied parabolic concrete arch. Inclined stirrups provide shear integrity and enforce composite action between the HCBs and the concrete deck. This paper focuses on evaluating the in-service performance of a newly constructed HCB bridge superstructure located on Route 205 in Colonial Beach, Virginia. A live load test was conducted using tandem axle dump trucks under both quasi-static and dynamic conditions. Results obtained from the experimental investigation were used to determine three key behavior characteristics. Dynamic amplification and lateral load distribution were found to be reasonable in comparison to the assumed design values....

  10. Characterization of two WESF [Waste Encapsulation and Storage Facility] capsules after five years of service

    International Nuclear Information System (INIS)

    Two Waste Encapsulation and Storage Facility (WESF) 137Cs capsules have been analyzed destructively after five years of service in the Sandia Irradiator for Dried Sewage Solids (SIDSS). The program concentrated on studies of the inner capsule, inner capsule weld areas, and analysis of the CsCl salt. No measurable corrosion was observed on the capsule wall or welds after the five years in the SIDSS Facility. The operating temperatures of the inner capsule wall were calculated to be between 140 and 180/degree/C. Radiochemistry and isotopic analyses provided data for specific activity calculations. There was good correlation between the measured calorimetry of the capsules before sectioning, 53 and 55 kCi, and the activity calculations, 54 and 59 kCi, respectively. 21 refs., 43 figs., 18 tabs

    In the present review, we reexamine the photomagnetic properties of the [Fe (PM-BiA) sub 2 (NCS) sub 2], cis-bis(thiocyanato)-bis[(N-2'-pyridylmethylene)-4-(aminobiphenyl)] iron(II), compound which exhibits, depending on the synthetic method, an exceptionally abrupt spin transition (phase 1) with a very narrow hysteresis (T sub 1 sub / sub 2 arrow down = 168 K and T sub 1 sub / sub 2 arrow up = 173 K) or a gradual spin conversion (phase II) occurring at 190 K. In both cases, light irradiation in the tail of the sup 1 MLCT-LS absorption band, at 830 nm, results in the population of the high-spin state according to the light-induced excited spin-state trapping (LIESST) effect. The capacity of a compound to retain the light-induced HS information, estimated through the T(LIESST) experiment, is determined for both phases. Interestingly, the shape of the T(LIESST) curve is more gradual for the phase II than for the phase I and the T(LIESST) value is found considerably lower in the case of the phase II. The kinetic...

    This study characterized the use of research community partnerships (RCPs) to tailor evidence-based intervention, training, and implementation models for delivery across different childhood problems and service contexts using a survey completed by project principal investigators and community partners. To build on previous RCP research and to explicate the tacit knowledge gained through collaborative efforts, the following were examined: (1) characteristics of studies using RCP models; (2) RCP functioning, processes, and products; (3) processes of tailoring evidence-based practices for community implementation; and (4) perceptions of the benefits and challenges of collaborating with community providers and consumers. Results indicated that researchers were solely or jointly involved in the formation of almost all of the RCPs; interpersonal and operational processes were perceived as primary challenges; community partners' roles included greater involvement in implementation and participant recruitment than more traditional research activities; and the partnership process was perceived to increase the relevance and "fit" of interventions and research.

    2014-09-01

    Full Text Available Design of an Active Queue Management scheme at the Access Point to address the problem of congestion control, packet delay variation and packet loss rate is discussed. The proposed mechanism calculates and adjusts redundancy rate adaptively at the access point by considering both network traffic load and wireless channel condition. Real-time applications such as Mobile learning and smart learning need the special treatment and require differentiated QoS to satisfy the client who is ready to pay more than others. Maintaining the jitter value of the multimedia packets below the threshold is essential to guarantee the desirable quality of the video at the receiver. The work initially concentrates on minimizing the packet loss of such priority flows and they have to be given place in the queue even at the time of buffer overflow. Thus the proposed work uses push-out policy to provide differentiated services to the multimedia flow which achieves considerable improvement in the video quality at the receiver. The considerable decrease in packet loss rate and special treatment in the queue of the access point lowers the packet delay variation of the multimedia flow. The results show that the AQM used at the access point effectively achieves low packet loss, low jitter using differentiated FEC rate calculation without generating congestion in the wireless network.

    Land subsidence is a common natural hazard striking extensive areas worldwide that can be triggered by geological and/or anthropogenic factors. In many cases, subsidence affects urbanized areas and causes remarkable economic loss. Adopted policies and solutions for land subsidence management can be various, but despite this variability, where mitigation methods have to be put into practice, the detailed mapping, characterization and simulation of subsidence have to precede their design and implementation. In the framework of the Terrafirma Project (www.terrafirma.eu.com), the exploitation of Persistent Scatterer Interferometry (PSI) for subsidence analysis has been promoted. Satellite interferometry, thanks to its wide spatial coverage and its millimeter accuracy, is ideally suited for the measurement of the spatial extent and magnitude of surface deformations associated with subsidence phenomena. Three validated case studies, where subsidence is caused by different factors, are presented here: the wide area of Rome (Italy), the Gioia Tauro plain (Italy) and the Kalochori village (Greece). These case studies have been selected with the aim of showing the main activities that must be covered and performed when dealing with geohazard investigations, i.e., mapping, monitoring and modeling. Particularly, data from ERS1/2, Envisat and Radarsat satellites have been exploited to map ground deformation in the area of Rome and to monitor the ground subsidence in the Gioia Tauro plain. Due to the large availability of geological and geotechnical data, the area of Kalochori village has been selected to model the land subsidence by applying Finite Element simulation. Results of the simulation have been validated with PSI techniques.

    MicroRNAs (miRNAs), small non-coding RNA molecules, are important biomarkers for research and medical purposes. Here, we describe the development of a fast and simple method using highly fluorescent oligonucleotide-silver nanocluster probes (DNA/AgNCs) to efficiently detect specific miRNAs. Due to the great sequence diversity of miRNAs in humans and other organisms, a uniform strategy for miRNA detection is attractive. The concept presented is an oligonucleotide-based locking-to-unlocking system that can be endowed with miRNA complementarity while maintaining the same secondary structure. The locking-to-unlocking system is based on fold-back anchored DNA templates that consist of a cytosine-rich loop for AgNCs stabilization, an miRNA recognition site and an overlap region for hairpin stabilization. When an miRNA is recognized, fluorescence in the visible region is specifically extinguished in a concentration-dependent manner. Here, the exact composition of the fold-back anchor for the locking-to-unlocking system has been systematically optimized, balancing propensity for loop-structure formation, encapsulation of emissive AgNCs and target sensitivity. It is demonstrated that the applied strategy successfully can detect a number of cancer related miRNAs in RNA extracts from human cancer cell lines. PMID:26681688

    Battelle Energy Alliance, LLC, managing and operating contractor for the U.S. Department of Energy's Idaho National Laboratory, is the lead laboratory for U.S. Department of Energy Advanced Vehicle Testing. Battelle Energy Alliance, LLC contracted with Intertek Testing Services, North America (ITSNA) to collect data on federal fleet operations as part of the Advanced Vehicle Testing Activity's Federal Fleet Vehicle Data Logging and Characterization study. The Advanced Vehicle Testing Activity study seeks to collect data to validate the utilization of advanced electric drive vehicle transportation. This report focuses on the Golden Gate National Recreation Area (GGNRA) fleet to identify daily operational characteristics of select vehicles and report findings on vehicle and mission characterizations to support the successful introduction of plug-in electric vehicles (PEVs) into the agencies' fleets. Individual observations of these selected vehicles provide the basis for recommendations related to electric vehicle adoption and whether a battery electric vehicle or plug-in hybrid electric vehicle (PHEV) (collectively PEVs) can fulfill the mission requirements. GGNRA identified 182 vehicles in its fleet, which are under the management of the U.S. General Services Administration. Fleet vehicle mission categories are defined in Section 4, and while the GGNRA vehicles conduct many different missions, only two (i.e., support and law enforcement missions) were selected by agency management to be part of this fleet evaluation. The selected vehicles included sedans, trucks, and sport-utility vehicles. This report will show that battery electric vehicles and/or PHEVs are capable of performing the required missions and providing an alternative vehicle for support vehicles and PHEVs provide the same for law enforcement, because each has a sufficient range for individual trips and time is available each day for charging to accommodate multiple trips per day.

    Battelle Energy Alliance, LLC, managing and operating contractor for the U.S. Department of Energy’s Idaho National Laboratory, is the lead laboratory for the U.S. Department of Energy’s Advanced Vehicle Testing. Battelle Energy Alliance, LLC contracted with Intertek Testing Services, North America (ITSNA) to collect data on federal fleet operations as part of the Advanced Vehicle Testing Activity’s Federal Fleet Vehicle Data Logging and Characterization study. The Advanced Vehicle Testing Activity study seeks to collect data to validate the use of advanced electric drive vehicle transportation. This report focuses on the Fort Vancouver National Historic Site (FVNHS) fleet to identify daily operational characteristics of select vehicles and report findings on vehicle and mission characterizations to support the successful introduction of electric vehicles (EVs) into the agencies’ fleet. Individual observations of the selected vehicles provided the basis for recommendations related to EV adoption and whether a battery electric vehicle (BEV) or plug-in hybrid electric vehicle (PHEV) (collectively plug-in electric vehicles) could fulfill the mission requirements. FVNHS identified three vehicles in its fleet for consideration. While the FVNHS vehicles conduct many different missions, only two (i.e., support and pool missions) were selected by agency management to be part of this fleet evaluation. The logged vehicles included a pickup truck and a minivan. This report will show that BEVs and PHEVs are capable of performing the required missions and providing an alternative vehicle for both mission categories, because each has sufficient range for individual trips and time available each day for charging to accommodate multiple trips per day. These charging events could occur at the vehicle’s home base, high-use work areas, or in intermediate areas along routes that the vehicles frequently travel. Replacement of vehicles in the current fleet would result in

    Synthesis, structural and electrical properties are given for a new organic stannous pseudo halide material. The structure of the [C{sub 2}H{sub 10}N{sub 2}][(SnCl(NCS){sub 2}]{sub 2} reveals that the adjacent Sn(II) centres are bridged by a pair of SCN{sup -} anions to form a 1-D array giving rise to the anionic chains (SnCl(NCS){sub 2}){sub n}{sup n-}. These chains are themselves interconnected by means of N-H Horizontal-Ellipsis Cl(S) hydrogen bonds originating from the organic cation [(NH{sub 3}){sub 2}(CH{sub 2}){sub 2}]{sup 2+}. The AC impedance measurements were performed as a function of both frequency and temperature. The electrical conduction and dielectric relaxation have been studied. The activation energy associated with the electrical relaxation determined from the electric modulus spectra was found close to that of the activation energy obtained for DC conductivity. The conduction mechanisms are attributed to the quantum mechanical tunneling model in phase I and to the proton hopping among hydrogen vacancies in phase II. - Graphical abstract: Atomic coordination in [C2H10N2][SnCl(NCS)2)2]. Highlights: Black-Right-Pointing-Pointer X-ray diffraction analysis shows the 1D network character of the structure. Black-Right-Pointing-Pointer DSC experiments show a phase transition at 336 K. Black-Right-Pointing-Pointer The AC conductivity is interpreted in terms of Jonsher's law. Black-Right-Pointing-Pointer Two conduction mechanisms are proposed for phase I and II.

  8. A dosimetry study comparing NCS report-2, IAEA TRS-381, AAPM TG-51 and IAEA TRS-398 for high energy photon beams

    International Nuclear Information System (INIS)

    In the last 5 years the American Association of Physicists in Medicine Task group 51 (AAPM TG-51) and the International Atomic Energy Agency (IAEA) published a new high-energy photon and electron dosimetry protocol. These protocols are based on the use of an ion chamber having an absorbed-dose to water calibration factor. These are different from the previous NCS report-2 and IAEA TRS-277 protocols, which require air kerma calibration factor, the aim of this study is to present the dose comparison between various dosimetry protocols and the IAEA TRS-398 protocol for clinical reference dosimetry of high energy photon beams. The absorbed-dose to water measured according to the NCS Report-2, International Atomic Energy Agency technical Report Series No. 277 (IAEA TRS-277) and, TG-51 are compared to that measured using the TRS-398 protocol. This study shows that the absorbed dose which is measured with The IAEA TRS-398 formalisms is higher than that calculated with NCS Report-2 and IAEA TRS-277 formalisms within range from 0.4 to 1.3% and from 0.7 to 2.1% respectively for different higher energy photon beams of Co-60, 6, 8 and 18 MV. as sensed by different ionization chambers, The chambers used are PTW 30001, 30004, and NE-2571; which have calibration factors NK and ND,W traceable to the Bureau International des Poids et Measures (BIPM). In contrast, the absorbed-dose to water measured according to TG-51 is in good agreement with TRS-398 within about 0.3% for photon beams

    Plastidic uracil salvage is essential for plant growth and development. So far, PLUTO, the plastidic nucleobase transporter from Arabidopsis thaliana is the only known uracil importer at the inner plastidic membrane which represents the permeability barrier of this organelle. We present the first homology model of PLUTO, the sole plant NCS1 member from Arabidopsis based on the crystal structure of the benzyl hydantoin transporter MHP1 from Microbacterium liquefaciens and validated by molecular dynamics simulations. Polar side chains of residues Glu-227 and backbones of Val-145, Gly-147 and Thr-425 are proposed to form the binding site for the three PLUTO substrates uracil, adenine and guanine. Mutational analysis and competition studies identified Glu-227 as an important residue for uracil and to a lesser extent for guanine transport. A differential response in substrate transport was apparent with PLUTO double mutants E227Q G147Q and E227Q T425A, both of which most strongly affected adenine transport, and in V145A G147Q, which markedly affected guanine transport. These differences could be explained by docking studies, showing that uracil and guanine exhibit a similar binding mode whereas adenine binds deep into the catalytic pocket of PLUTO. Furthermore, competition studies confirmed these results. The present study defines the molecular determinants for PLUTO substrate binding and demonstrates key differences in structure-function relations between PLUTO and other NCS1 family members.

  17. Anomalous behaviour of the in-plane electrical conductivity of the layered superconductor κ-(BEDT-TTF)2Cu(NCS)2

    International Nuclear Information System (INIS)

    The apparent quasiparticle scattering rates in high-quality crystals of the quasi-two-dimensional superconductor κ-(BEDT-TTF)2Cu(NCS)2 are studied using the Shubnikov-de Haas effect and megahertz penetration-depth experiments. The width of the superconducting transition observed in the megahertz experiments, taken in conjunction with the field dependence of the Shubnikov-de Haas oscillations, gives evidence that the broadening of the Landau levels is primarily caused by spatial inhomogeneities. This indicates a quasiparticle lifetime for the Landau states >> 3 ps. The megahertz data can also be used to derive an apparent scattering time (0.14- 0.56 ps) from the skin depth. This is much shorter than the Landau-state lifetime, in strong contrast to the expectations of Landau Fermi-liquid theory. The simplest explanation for the data is that only a fraction of the crystal contributes to the metallic conductivity, an observation which may be related to the recently observed 'glassy' transition in κ-(BEDT-TTF)2Cu(NCS)2.

The potential energy surfaces expressed in the Morse form for Fe–N interactions are deduced from molecular DFT calculations and they allow producing Infra Red and Raman frequencies. These Fe–N potentials inserted in a classical force field lead from MD calculations to the relative energies of the high spin and low spin configurations of the orthorhombic structure. The MD investigations have also allowed assessing the experimental (P, T) phase diagram by showing the monoclinic polymorph in its two spin-states, and generating two triple points.

    With the rapid rise in the development of Web technologies and climate services across NOAA, there has been an increasing need for greater collaboration regarding NOAA's online climate services. The drivers include the need to enhance NOAA's Web presence in response to customer requirements, emerging needs for improved decision-making capabilities across all sectors of society facing impacts from climate variability and change, and the importance of leveraging climate data and services to support research and public education. To address these needs, NOAA (during fiscal year 2009) embarked upon an ambitious program to develop a NOAA Climate Services Portal (NCS Portal). Four NOAA offices are leading the effort: 1) the NOAA Climate Program Office (CPO), 2) the National Ocean Service's Coastal Services Center (CSC), 3) the National Weather Service's Climate Prediction Center (CPC), and 4) the National Environmental Satellite, Data, and Information Service's (NESDIS) National Climatic Data Center (NCDC). Other offices and programs are also contributing in many ways to the effort. A prototype NCS Portal is being placed online for public access in January 2010, http://www.climate.gov. This website only scratches the surface of the many climate services across NOAA, but this effort, via direct user engagement, will gradually expand the scope and breadth of the NCS Portal to greatly enhance the accessibility and usefulness of NOAA's climate data and services.

  2. Characterizing high-velocity angular vestibulo-ocular reflex function in service members post-blast exposure.

    Blasts (explosions) are the most common mechanism of injury in modern warfare. Traumatic brain injury (TBI) and dizziness are common sequelae associated with blasts, and many service members (SMs) report symptoms worsen with activity. The purpose of this study was to measure angular vestibulo-ocular reflex gain (aVOR) of blast-exposed SMs with TBI during head impulse testing. We also assessed their symptoms during exertion. Twenty-four SMs recovering from TBI were prospectively assigned to one of two groups based on the presence or absence of dizziness. Wireless monocular scleral search coil and rate sensor were used to characterize active and passive yaw and pitch head and eye rotations. Visual analog scale (VAS) was used to monitor symptoms during fast walking/running. For active yaw head impulses, aVOR gains were significantly lower in the symptomatic group (0.79 ± 0.15) versus asymptomatic (0.87 ± 0.18), but not for passive head rotation. For pitch head rotation, the symptomatic group had both active (0.915 ± 0.24) and passive (0.878 ± 0.22) aVOR gains lower than the asymptomatic group (active 1.03 ± 0.27, passive 0.97 ± 0.23). Some SMs had elevated aVOR gain. VAS scores for all symptoms were highest during exertion. Our data suggest symptomatic SMs with TBI as a result of blast have varied aVOR gain during high-velocity head impulses and provide compelling evidence of pathology affecting the vestibular system. Potential loci of injury in this population include the following: disruption of pathways relaying vestibular efference signals, differential destruction of type I vestibular hair cells, or selective damage to irregular afferent pathways-any of which may explain the common discrepancy between reports of vestibular-like symptoms and laboratory testing results. Significantly reduced pitch aVOR in symptomatic SMs and peak symptom severity during exertional testing support earlier findings in the chronic blast-exposed active duty SMs. PMID

  3. Proposal of a methodology to be applied for the characterization of external exposure risk of employees in nuclear medicine services

    International Nuclear Information System (INIS)

    Nuclear medicine procedure requires the administration of radioactive material by injection, ingestion or inhalation. After incorporation, the patient becomes a mobile source of radiation and, after their examination; they can irradiate everyone on their way out of the Nuclear Medicine Service (NMS). A group of workers in this path is considered a critical group, but there are no conviction on this classification, because there are not measurements available. Thus, workers claiming for occupationally exposed individual's (OEI) rights are common. Employers are always in a complex situation, because if they decided to undertake the individual external monitoring of the critical working groups, the Court considers all as OEI and employers are taxed. On the other hand, if they do not provide monitoring, it is impossible to prove that these workers were not exposed to effective doses higher than individual annual public's limit and they lose the actions, too. This work proposes a methodology to evaluate, using TLD environmental monitors, air kerma rate at critical staff points in a NMS. This method provides relevant information about critical groups' exposure. From these results, the clinic or hospital may prove technically, without individual monitoring of employees, the classification of areas and can estimate the maximum flow of patients in the free areas which guarantees exposures below the public individual dose limit. This methodology has been applied successfully to a private clinic in Rio de Janeiro, which operates a NMS. The only critical group that received exposure statistically different from clinic background radiation was that on the antechamber of the NMS. This is a site that should be characterized as a supervised area and the group of workers in this environment as OEI, as the estimated extrapolated annual effective dose in this position was 1.2 +- 0.7 mSv/year, above the public annual limit (1,0 mSv/year). Normalizing by the number of patients, it can

    Urban sprawl and the related landscape fragmentation is a Europe-wide challenge in the context of sustainable urban planning. The URBan land recycling Information services for Sustainable cities (URBIS) project aims for the development, implementation, and validation of web-based information services for urban vacant land in European functional urban areas in order to provide end-users with site specific characteristics and to facilitate the identification and evaluation of potential development areas. The URBIS services are developed based on open geospatial data. In particular, the Copernicus Urban Atlas thematic layers serve as the main data source for an initial inventory of sites. In combination with remotely sensed data like SPOT5 images and ancillary datasets like OpenStreetMap, detailed site specific information is extracted. Services are defined for three main categories: i) baseline services, which comprise an initial inventory and typology of urban land, ii) update services, which provide a regular inventory update as well as an analysis of urban land use dynamics and changes, and iii) thematic services, which deliver specific information tailored to end-users' needs.

IR spectra of the complexes show the reduction in the thioureide stretching frequency due to the increase in coordination around the zinc ion and the resultant increase in electron density. The charge transfer transitions are observed in the region 260 – 320 nm by electronic spectra. Thermal studies show a single stage weight loss. The cyclic voltammetric study on the complexes show an increase of electron density on zinc in the adducts compared to [Zn(dtc2]2. The bond valence sum(BVS analysis shows the values to be close to '2', which is equivalent to the formal oxidation state of zinc in the zinc complexes.

    MicroRNAs (miRNAs), small non-coding RNA molecules, are important biomarkers for research and medical purposes. Here, we describe the development of a fast and simple method using highly fluorescent oligonucleotide-silver nanocluster probes (DNA/AgNCs) to efficiently detect specific miRNAs. Due to...... the great sequence diversity of miRNAs in humans and other organisms, a uniform strategy for miRNA detection is attractive. The concept presented is an oligonucleotide-based locking-to-unlocking system that can be endowed with miRNA complementarity while maintaining the same secondary structure. The...... strategy successfully can detect a number of cancer related miRNAs in RNA extracts from human cancer cell lines....

    A series of spin transition complexes [Fe1-xZnx(dpp)2(NCS)2]py (x = 0.05, 0.10, 0.15. 0.20, 0.25, and 0.40;py=pyridine) has been synthesized and studied by Mossbauer spectroscopy. The high-spin structure is frozen at room temperature, and the induced meta-stable high-spin phase by the so-called rapid cooling method is monitored by temperature and time-dependent Mossbauer spectra. The investigation on dynamic relaxation of the high-spin state to the low-spin state at 80 K reveals sigmoid behaviour and existence of cooperative effect for low diluted complexes. This cooperative effect is wrecked by the dilution of Zn(Ⅱ) ions in Fe(Ⅱ) ion sites, and relaxation curves gradually become to obey the first-order kinetics as the ratio of the dilution increases.

    Hierarchically nanostructured porous carbonated hydroxyapatite coatings (HNPCs) on Ti6A14V substrate were fabricated by a two-stage application route:fabrication of nacre coatings (NCs) on Ti6A14V substrate by electrophoretic technique,and conversion of NCs to HNPCs in a phosphate buffer solution (PBS) by microwave irradiation method.Their samples were characterized by using XRD,FT-IR,SEM,TEM,and N2 adsorption-desorption isotherms.The results show that the microwave irradiation technique improves obviously the conversion rate of NCs to HNPCs as compared with conventional method.After soaking the NCs in the PBS,calcium ions are released from the nacre particles and react with phosphate ions to form carbonated hydroxyapatite nanoparticles.These nanoparticles aggregate to form the plate-like carbonated apatite.The mesopores with a size of about 3.9 nm and macropores with the diameters of 1~4 μm exist within and among the carbonated apatite plates,respectively.Simulated body fluid immersion tests reveal that the HNPCs have a good in vitro bioactivity.

  15. Nondestructive testing for microstructural characterization in 9Cr-1Mo ferritic steel towards assessment of fabrication quality and in-service degradation

    International Nuclear Information System (INIS)

    The paper discusses the usefulness of non destructive testing for microstructural characterization in 9Cr-1Mo ferritic steel. Ultrasonic velocity and attenuation measurements and spectral analysis have been used in a complementary way for characterizing Ac1 and Ac3 temperatures, amount of martensite and ferrite, dissolution of V4C3 and NbC and formation of δ-ferrite. The microstructural degradation occurring due to thermal ageing and creep has also been studied by ultrasonic velocity measurements. Magnetic Barkhausen noise technique has been used for estimating the extent of various regions in heat affected zone (HAZ) of 9Cr-1Mo ferritic steel weldment. The same technique has been used for the assessment of low cycle fatigue damage in 9Cr-1Mo steel. The study establishes that non destructive methods can be used for the assessment of fabrication quality and in service degradation of the components. (author)

  16. Nondestructive characterization of materials A growing demand for describing damage and service-life-relevant aging processes in plant components

    International Nuclear Information System (INIS)

    The nondestructive detection and characterization of damage to materials poses a challenge to instrumentation and inspection technology. A reliable method has yet to be developed anywhere in the world which is sufficiently rugged to be used on components in an industrial environment. The application-oriented studies conducted to date have demonstrated the complex overlapping of influences exerted on nondestructive measurement variables by the damage to be detected and by other material states and properties. The nondestructive detection and characterization of material damage will not offer any realistic chance of success until the material and component state is adequately characterized prior to the occurrence of the damage and variables are used which provide various types of information on the states and properties resulting from various interactions with the material. The process approaches and measurement techniques developed by the Institute for Nondestructive Testing are presented and evaluated below. The characterization of the initial state of a component with respect to its homogeneity and isotropy of its properties is possible by way of ultrasonic and magnetic techniques. Both techniques are also successfully employed in characterizing surface and bulk stress states in components. Adaptation of the sensor systems and material-specific preliminary testing are possibly required prior to actual application under practical conditions in individual cases. The same applies to the analysis of the anisotropy of material properties. Detecting areas of plastic deformation is possible via ultrasonic and magnetic techniques: quantification requires calibration, e.g. via a tensile test. (orig.)

    Reaction of iron(II) thiocyanate with an excess of trans-1,2-bis(4-pyridyl)-ethylene (bpe) in acetonitrile at room temperature leads to the formation of [Fe(NCS)(2)(bpe)(2)·(bpe)] (1), which is isotypic to its Co(II) analogue. Using slightly different reaction conditions the literature known compound [Fe(NCS)(2)(bpe)(2)(H(2)O)(2)] (2) was obtained as a phase pure material. Simultaneous differential thermoanalysis and thermogravimetry prove that the hydrate 2 transforms into the anhydrate [Fe(NCS)(2)(bpe)(2)] (3), that decomposes on further heating into the new ligand-deficient 1:1 compound of composition [Fe(NCS)(2)(bpe)](n) (4), which can also be obtained directly by thermal decomposition of 1. Further investigations reveal that 4 can also be prepared under solvothermal conditions, and single crystal structure analysis shows that the iron(II) cations are linked via μ-1,3 bridging thiocyanato anions into chains, that are further connected into layers by the bpe ligands. Magnetic measurements, performed on powder samples, prove that 1 and 2 show only Curie-Weiss behavior, whereas in 4 antiferromagnetic ordering with a Néel temperature of 5.0 K is observed. At T < 4.0 K a two-step metamagnetic transition occurs at applied magnetic fields of 1300 and 1775 Oe. The magnetic properties are discussed and compared with those of related compounds.

  3. Characterization of silver/polystyrene nanocomposites prepared by in situ bulk radical polymerization

    International Nuclear Information System (INIS)

    Graphical abstract: - Highlights: • Synthesis and characterization of polystyrene nanocomposites based on Ag nanoparticles. • The glass transition temperature decreased in nanocomposites with respect to the pure polymer. • Resistance of the polymer to thermal degradation enhanced with Ag nanoparticles content. - Abstract: Nanocomposites (NCs) with different content of silver nanoparticles (Ag NPs) embeded in polystyrene (PS) matrix were prepared by in situ bulk radical polymerization. The nearly monodisperse Ag NPs protected with oleylamine were synthesized via organic solvo-thermal method and further used as a filler. The as-prepared spherical Ag NPs with diameter of 7.0 ± 1.5 nm were well dispersed in the PS matrix. The structural properties of the resulting Ag/PS NCs were characterized by transmission electron microscope (TEM) and Fourier transform infrared (FTIR) spectroscopy, while optical properties were characterized using optical absorption measurements. The gel permeation chromatography (GPC) measurements showed that the presence of Ag NPs stabilized with oleylamine has no influence on the molecular weight and polydispersity of the PS matrix. The influence of silver content on the thermal properties of Ag/PS NCs was investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results indicated that resistance of PS to thermal degradation was improved upon incorporation of Ag NPs. The Ag/PS NCs have lower glass transition temperatures than neat PS because loosely packed oleylamine molecules at the interface caused the increase of free volume and chain segments mobility near the surface of Ag NPs

    Several wildfire prevention programs in Spain are using grazing livestock to maintain fuelbreaks with low levels of biomass. Even though shepherds are remunerated for these services, many of their farms are hardly viable in the current socio-economic context. By analyzing 54 small ruminant farms participating in the Grazed Fuelbreak Network in Andalusia (southern Spain), this research aimed to identify the main types and characteristics of such farms and, considering the challenges they are facing, propose strategies to improve both their economic viability and their effectiveness in fuelbreak grazing. Based on data collected through a survey on key farm management aspects, a multivariate analysis was performed and four main types of farm were identified: two clusters of dairy goat farms and two composed mostly of meat-purpose sheep farms. Farms in all clusters could benefit from improvements in the feeding and reproductive management of livestock, either to enhance their productivity or to make better use of the pasture resources available. Dairy goat farms remain more dependent on external animal feed to ensure a better lactation, therefore they should either diminish their workforce costs per animal or sell transformed products directly to consumers to improve their economic viability. Best fuelbreak grazing results were related to larger flocks combining sheep and goats, lower ratios of fuelbreak surface area per animal, and longer (year-long) grazing periods on fuelbreaks. Therefore, such farm features and adjusted fuelbreak assignments should be favored in wildfire prevention programs using grazing services. PMID:26657367

    Energy use patterns in many of California's fastest-growing industries are not typical of those in the mix of industries elsewhere in the US. Many California firms operate small and medium-sized facilities, often in buildings used simultaneously or interchangeably for commercial (office, retail, warehouse) and industrial activities. In these industrial subsectors, the energy required for building services'' to provide occupant comfort and necessities (lighting, HVAC, office equipment, computers, etc.) may be at least as important as the more familiar process energy requirements -- especially for electricity and on-peak demand. In this report, published or unpublished information on energy use for building services in the industrial sector have been compiled and analyzed. Seven different sources of information and data relevant to California have been identified. Most of these are studies and/or projects sponsored by the Department of Energy, the California Energy Commission, and local utilities. The objectives of these studies were diverse: most focused on industrial energy use in general, and, in one case, the objective was to analyze energy use in commercial buildings. Only one of these studies focused directly on non-process energy use in industrial buildings. Our analysis of Northern California data for five selected industries shows that the contribution of total electricity consumption for lighting ranges from 9.5% in frozen fruits to 29.1% in instruments; for air-conditioning, it ranges from nonexistent in frozen fruits to 35% in instrument manufacturing. None of the five industries selected had significant electrical space heating. Gas space heating ranges from 5% in motor vehicles facilities to more than 58% in the instrument manufacturing industry. 15 refs., 15 figs., 9 tabs.

  9. Characterization by notched and precracked Charpy tests of the in-service degradation of RPV steel fracture toughness

    International Nuclear Information System (INIS)

    The current engineering and regulatory practice to estimate fracture toughness safety margins for nuclear reactor pressure vessels (RPVs) relies heavily on the CVN impact test. Techniques to estimate in-service toughness degradation directly using a variety of precracked specimens are under development worldwide. Emphasis is on their miniaturization. In the nuclear context, it is essential to address many issues such as representativity of the surveillance programs with respect to the vessel in terms of materials and environment, transferability of test results to the structure (constraint and size effects), lower bound toughness certification, creadibility relative to trends of exising databases. An enhanced RPV surveillance strategy in under development in Belgium. It combines state-of-the-art micromechanical and damage modelling to the evaluation of CVN load-deflection signals, tensile stress-strain curves and slow-bend tests of reconstituted precracked Charpy specimens. A probabilistic micromechanical model has been established for static and dynamic transgranular cleavage initiation fracture toughness in the ductile-brittle transition temperature range. This model allows to project toughness bounds for any steel embrittlement condition from the corresponding CVN and static tensile properties, using a single scaling factor defined by imposing agreement with toughness tests in a single condition. The outstanding finding incorporated by this toughness transfer model is that the microcleavage fracture stress is affected by temperature in the ductile-brittle transition and that this influence is strongly correlated to the flow stress: this explains the shape of the KIcn KId temperature curves as well as the actual magnitude of the strain rate and irradiation effects. Furthermore, CVN crack arrest loads and fracture appearance are also taken advantage of in order to estimate KIa degradation. Finally, the CVN-tensile load-temperature diagram provides substantial

This model allows to project toughness bounds for any steel embrittlement condition from the corresponding CVN and static tensile properties, using a single scaling factor defined by imposing agreement with toughness tests in a single condition. The outstanding finding incorporated by this toughness transfer model is that the microcleavage fracture stress is affected by temperature in the ductile-brittle transition and that this influence is strongly correlated to the flow stress: this explains the shape of the K{sub Ic}n K{sub Id} temperature curves as well as the actual magnitude of the strain rate and irradiation effects. Furthermore, CVN crack arrest loads and fracture appearance are also taken advantage of in order to estimate K{sub Ia} degradation. Finally, the CVN-tensile load-temperature diagram

    The apparent quasiparticle scattering rates in high-quality crystals of the quasi-two-dimensional superconductor kappa-(BEDT-TTF) sub 2 Cu(NCS) sub 2 are studied using the Shubnikov-de Haas effect and megahertz penetration-depth experiments. The width of the superconducting transition observed in the megahertz experiments, taken in conjunction with the field dependence of the Shubnikov-de Haas oscillations, gives evidence that the broadening of the Landau levels is primarily caused by spatial inhomogeneities. This indicates a quasiparticle lifetime for the Landau states >> 3 ps. The megahertz data can also be used to derive an apparent scattering time (0.14- 0.56 ps) from the skin depth. This is much shorter than the Landau-state lifetime, in strong contrast to the expectations of Landau Fermi-liquid theory. The simplest explanation for the data is that only a fraction of the crystal contributes to the metallic conductivity, an observation which may be related to the recently observed 'glassy' transition in k...

  12. Use of InSpectorTM 1 1000 Instrument with LaBr3 for Nuclear Criticality Safety (NCS) Applications at the Westinghouse Hematite Decommissioning Project (HDP) - 13132

    International Nuclear Information System (INIS)

    The Westinghouse Hematite Decommissioning Project (HDP) is a former nuclear fuel cycle facility that is currently undergoing decommissioning. One aspect of the decommissioning scope is remediation of buried nuclear waste in unlined burial pits. The current Nuclear Criticality Safety program relies on application of criticality controls based on radiological setpoints from a 2 x 2 Sodium Iodide (NaI) detector. Because of the nature of the material buried (Low Enriched Uranium (LEU), depleted uranium, thorium, and radium) and the stringent threshold for application of criticality controls based on waste management (0.1 g 235U/L), a better method for 235U identification and quantification has been developed. This paper outlines the early stages of a quick, in-field nuclear material assay and 235U mass estimation process currently being deployed at HDP. Nuclear material initially classified such that NCS controls are necessary can be demonstrated not to require such controls and dispositioned as desired by project operations. Using Monte Carlo techniques and a high resolution Lanthanum Bromide (LaBr) detector with portable Multi-Channel Analyzer (MCA), a bounding 235U mass is assigned to basic geometries of nuclear material as it is excavated. The deployment of these methods and techniques has saved large amounts of time and money in the nuclear material remediation process. (authors)

    Full Text Available Distinctions between rural and urban environments produce different frequencies of traumatic exposures and psychiatric disorders. We examine the prevalence of psychiatric disorders and frequency of trauma exposures by position on the rural-urban continuum.The National Comorbidity Survey Replication (NCS-R was used to evaluate psychiatric disorders among a nationally-representative sample of the U.S. population. Rurality was designated using the Department of Agriculture's 2003 rural-urban continuum codes (RUCC, which differentiate counties into levels of rurality by population density and adjacency to metropolitan areas. Lifetime psychiatric disorders included post-traumatic stress disorder (PTSD, anxiety disorders, major depressive disorder, mood disorders, impulse-control disorders, and substance abuse. Trauma exposures were classified as war-related, accident-related, disaster-related, interpersonal or other. Weighted logistic regression models examined the odds of psychiatric disorders and trauma exposures by position on the rural-urban continuum, adjusted for relevant covariates.75% of participants were metropolitan, 12.2% were suburban, and 12.8% were from rural counties. The most common disorder reported was any anxiety disorder (38.5%. Drug abuse was more common among metropolitan (8.7%, p = 0.018, compared to nonmetropolitan (5.1% suburban, 6.1% rural participants. A one-category increase in rurality was associated with decreased odds for war-related trauma (aOR = 0.86, 95%CI 0.78-0.95. Rurality was not associated with risk for any other lifetime psychiatric disorders or trauma exposure.Contrary to the expectation of some rural primary care providers, the frequencies of most psychiatric disorders and trauma exposures are similar across the rural-urban continuum, reinforcing calls to improve mental healthcare access in resource-poor rural communities.

    Full Text Available Copper oxide and cobalt oxide (CuO, Co3O4 nanocrystals (NCs have been successfully prepared in a short time using microwave irradiation without any postannealing treatment. Both kinds of nanocrystals (NCs have been prepared using copper nitrate and cobalt nitrate as the starting materials and distilled water as the solvent. The resulted powders of nanocrystals (NCs were characterized by X-ray diffraction (XRD, transmission electron microscopy (TEM, scanning electron microscopy (SEM, and atomic force microscopy (AFM measurements. The obtained results confirm the presence of the both of oxides nanopowders produced during chemical precipitation using microwave irradiation. A strong emission under UV excitation is obtained from the prepared CuO and Co3O4 nanoparticles. The results show that the nanoparticles have high dispersion and narrow size distribution. The line scans of atomic force microscopy (AFM images of the nanocrystals (NCs sprayed on GaAs substrates confirm the results of both X-ray diffraction and transmission electron microscopy. Furthermore, vibrational studies have been carried out using Raman spectroscopic technique. Specific Raman peaks have been observed in the CuO and Co3O4 nanostructures, and the full width at half maximum (FWHM of the peaks indicates a small particle size of the nanocrystals.

    2012-12-01

    Since 2002, NOAA's National Weather Service (NWS) Climate Services Division (CSD) has offered numerous training opportunities to NWS staff. After eight-years of development, the training program offers three instructor-led courses and roughly 25 online (distance learning) modules covering various climate topics, such as: climate data and observations, climate variability and change, and NWS national / local climate products (tools, skill, and interpretation). Leveraging climate information and expertise available at all NOAA line offices and partners allows for the delivery of the most advanced knowledge and is a very critical aspect of the training program. The emerging NOAA Climate Service (NCS) requires a well-trained, climate-literate workforce at the local level capable of delivering NOAA's climate products and services as well as providing climate-sensitive decision support. NWS Weather Forecast Offices and River Forecast Centers presently serve as local outlets for the NCS climate services. Trained NWS climate service personnel use proactive and reactive approaches and professional education methods in communicating climate variability and change information to local users. Both scientifically-sound messages and amiable communication techniques are important in developing an engaged dialog between the climate service providers and users. Several pilot projects have been conducted by the NWS CSD this past year that apply the program's training lessons and expertise to specialized external user group training. The technical user groups included natural resources managers, engineers, hydrologists, and planners for transportation infrastructure. Training of professional user groups required tailoring instructions to the potential applications for each group of users. Training technical users identified the following critical issues: (1) knowledge of target audience expectations, initial knowledge status, and potential use of climate information; (2) leveraging

    Full Text Available Water resource management can prove to be a very difficult task. It is not an easy job trying to fulfill the current requirements of the Water Framework Directive1 (WFD 2000/60/EC especially because it is difficult to estimate what really ?good status? means according with WFD. In order to reach the ?good status? in a particular river basin the water manager needs to propose a so called Program of Measures, which identifies and proposes measures to be taken in order to lower the impact generated by human activities. All these measures are based on an evaluation of the supposed natural status and current status in the river basin. What we try to propose here is a model for an tegrated management plan approach based both on the natural functionality of the river but also on the ecosystem services and social functionalities generated by man made ponds in the river basin.

    Integrated services is the name given to several services grouped together under a single contract. Four key factors determine the success of integrated services projects: teamwork, common objectives, technology, and shared benefits. For oil companies, integration means smoother, more efficient operations by bringing service companies on board as part of the team. For the service industry, it means a radical change in the way business is conducted, taking on more responsibility in return for greater incentives. This article reviews the need for change and the approach Schlumberger has adopted to meet this challenge. 20 figs., 20 refs

    The preparation, X-ray structures and magnetic properties of two isostructural new charge transfer salts: (BO)[ M(isoq) 2(NCS) 4]; M=Cr III(1), Fe III(2) and isoq=isoquinoline are reported. Their structure consists of alternate organic and inorganic layers, each layer being formed by mixed columns of BO radical cations and paramagnetic metal complex anions. There are short intermolecular contacts between donor and anion (S2 anion· · ·S4 BO<3.5 Å) and between adjacent BO molecules (O· · · O1<3.2 Å). The two compounds are insulators. ESR measurements show single signal without separating the donor and anion spins. The magnetic measurements obey the Curie-Weiss law and revealed dominant antiferromagnetic interactions between anion spin and donor spin, but long-range magnetic ordering did not occur down to 2 K. This is directly related to structural reasons which were deduced from a comparison of the title compounds with other 1:1 salts containing same anion complexes and different donors.

The structure and properties of Cu{sub 2}O/CS–Fe{sub 3}O{sub 4} NCs were characterized by XRD, FT-IR, SEM, HRTEM, SAED, EDS, BET, VSM, XPS and UV–vis/DRS. The photocatalytic activity of Cu{sub 2}O/CS–Fe{sub 3}O{sub 4} NCs was evaluated by decolorization of reactive brilliant red X-3B (X-3B) under visible light irradiation. The characterization results indicated that Cu{sub 2}O/CS–Fe{sub 3}O{sub 4} NCs exhibited relatively large specific surface areas and special dimodal pore structure because Cu{sub 2}O was wrapped in chitosan matrix embedded with Fe{sub 3}O{sub 4} nanoparticles. The tight combination of magnetic Fe{sub 3}O{sub 4} and semiconductor Cu{sub 2}O through chitosan made the nanocomposites show good superparamagnetism and photocatalytic activity. It was found that X-3B could be decolorized more efficiently in acidic media than in neutral or alkaline media. The decolorization of X-3B was ascribed to the synergistic effect of photocatalysis and adsorption. Cu{sub 2}O/CS–Fe{sub 3}O{sub 4} NCs could be easily separated from the solution by an external magnet, and the decolorization rates of X-3B

This is a descriptive cross-sectional study that analyzed a sample of 703 cases. The results showed that 81.8% were male, aged 20 to 29 years. It was noted that 406 of them were wearing a helmet at the time of the accident. The accidents occurred most frequently on Sundays (19.3% between 18:00 and 24:00 hours (0.28%. The extremities were the most affected body segment, with 341 occurrences. Regarding the severity of injuries, it was found that 37.6% were superficial or mild (scrapes, cuts and bruises. These results demonstrate the need for educational campaigns to encourage the use of personal protective equipment among motorcyclists. The best way to reduce the risks and damages from motorcycle accidents is through primary prevention. For this, are needed integrated intersectoral actions aimed at reducing the incidence and severity of injuries.

  19. Reduced Activation Ferritic/Martensitic Steel Eurofer 97 as Possible Structural Material for Fusion Devices. Metallurgical Characterization on As-Received Condition and after Simulated Services Conditions

    International Nuclear Information System (INIS)

    Metallurgical Characterization of the reduced activation ferritic/martensitic steel Eurofer'97, on as-received condition and after thermal ageing treatment in the temperature range from 400 degree centigree to 600 degree centigree for periods up to 10.000 h, was carried out. The microstructure of the steel remained stable (tempered martensite with M23 C6 and MX precipitates) after the thermal ageing treatments studied in this work. In general, this stability was also observed in the mechanical properties. The Eurofer'97 steel exhibited similar values of hardness, ultimate tensile stress, 0,2% proof stress, USE and T03 regardless of the investigated material condition.

    Metallurgical Characterization of the reduced activation ferritic/martensitic steel Eurofer'97, on as-received condition and after thermal ageing treatment in the temperature range from 400 degree centigree to 600 degree centigree for periods up to 10.000 h, was carried out. The microstructure of the steel remained stable (tempered martensite with M{sub 2}3 C{sub 6} and MX precipitates) after the thermal ageing treatments studied in this work. In general, this stability was also observed in the mechanical properties. The Eurofer'97 steel exhibited similar values of hardness, ultimate tensile stress, 0,2% proof stress, USE and T{sub 0}3 regardless of the investigated material condition. However, ageing at 600 degree centigree for 10.000 ha caused a slight increase in the DBTT, of approximately 23. In terms of creep properties, the steel shows in general adequate creep rupture strength levels for short rupture times. However, the results obtained up to now for long time creep rupture tests at 500 degree centigree suggests a change in the deformation mechanisms. (Author) 62 refs.

    Full Text Available Small sized magnetite iron oxide nanoparticles (Fe3O4-NPs with were successfully synthesized on the surface of rice straw using the quick precipitation method in the absence of any heat treatment. Ferric chloride (FeCl3·6H2O, ferrous chloride (FeCl2·4H2O, sodium hydroxide (NaOH and urea (CH4N2O were used as Fe3O4-NPs precursors, reducing agent and stabilizer, respectively. The rice straw fibers were dispersed in deionized water, and then urea was added to the suspension, after that ferric and ferrous chloride were added to this mixture and stirred. After the absorption of iron ions on the surface layer of the fibers, the ions were reduced with NaOH by a quick precipitation method. The reaction was carried out under N2 gas. The mean diameter and standard deviation of metal oxide NPs synthesized in rice straw/Fe3O4 nanocomposites (NCs were 9.93 ± 2.42 nm. The prepared rice straw/Fe3O4-NCS were characterized using powder X-ray diffraction (PXRD, transmission electron microscopy (TEM, scanning electron microscopy (SEM, energy dispersive X-ray fluorescence (EDXF and Fourier transforms infrared spectroscopy (FT‒IR. The rice straw/Fe3O4-NCs prepared by this method have magnetic properties.

    This paper presents a refinement calculus for service components. We model the behaviour of individual service by a guarded design, which enables one to separate the responsibility of clients from the commitment made by the system, and to iden-tify a component by a set of failures and divergences. Protocols are introduced to coordinate the interactions between a component with the external environment. We adopt the notion of process refinement to formalize the substitutivity of components, and provide a complete proof method based on the notion of simulations.

    2009-03-11

    A combination of conventional and synchrotron-based techniques has been used to characterize the size-dependent structural and thermal properties of Ge nanocrystals (NCs) embedded in a silica (a-SiO{sub 2}) matrix. Ge NC size distributions with four different diameters ranging from 4.0 to 9.0 nm were produced by ion implantation and thermal annealing as characterized with small-angle x-ray scattering and transmission electron microscopy. The NCs were well represented by the superposition of bulklike crystalline and amorphous environments, suggesting the formation of an amorphous layer separating the crystalline NC core and the a-SiO{sub 2} matrix. The amorphous fraction was quantified with x-ray-absorption near-edge spectroscopy and increased as the NC diameter decreased, consistent with the increase in surface-to-volume ratio. The structural parameters of the first three nearest-neighbor shells were determined with extended x-ray-absorption fine-structure (EXAFS) spectroscopy and evolved linearly with inverse NC diameter. Specifically, increases in total disorder, interatomic distance, and the asymmetry in the distribution of distances were observed as the NC size decreased, demonstrating that finite-size effects govern the structural properties of embedded Ge NCs. Temperature-dependent EXAFS measurements in the range of 15-300 K were employed to probe the mean vibrational frequency and the variation of the interatomic distance distribution (mean value, variance, and asymmetry) with temperature for all NC distributions. A clear trend of increased stiffness (higher vibrational frequency) and decreased thermal expansion with decreasing NC size was evident, confirming the close relationship between the variation of structural and thermal/vibrational properties with size for embedded Ge NCs. The increase in surface-to-volume ratio and the presence of an amorphous Ge layer separating the matrix and crystalline NC core are identified as the main factors responsible for

    We report in detail the synthesis and characterization of V-shaped IrO2 nanowedges (NWs) with an angle of 110° between the two arms. The NWs were grown on top of rutile (R) phase TiO2 nanorods (NRs) sitting on a sapphire (SA)(100) substrate via metal-organic chemical vapor deposition (MOCVD) by using (C6H7)(C8H12)Ir and titanium-tetraisopropoxide (TTIP, Ti[OCH(CH3)2]4) as the source reagents. The surface morphology, structural, and spectroscopic properties of the as-deposited nanocrystals (NCs) were characterized by field emission scanning electron microscopy (FESEM), x-ray diffraction (XRD), micro-Raman spectroscopy, transmission electron microscopy (TEM), and selected-area electron diffractometry (SAED). The FESEM images and XRD patterns indicated growth of V-shaped IrO2(101) NWs on top of R-TiO2 NRs. The Raman spectrum showed the nanosize induced redshift and peak broadening of the IrO2 and rutile phase of TiO2 signatures with respect to that of the bulk counterparts. TEM and SAED characterizations of IrO2 NCs showed that the nanowedges were crystalline IrO2 with a twin plane of (101) and twin direction of [\\bar {1} 01] at the V-junction. The probable mechanisms for the formation of well-aligned IrO2 NWs are discussed.

    Nuclear medicine procedure requires the administration of radioactive material by injection, ingestion or inhalation. After incorporation, the patient becomes a mobile source of radiation and, after their examination; they can irradiate everyone on their way out of the Nuclear Medicine Service (NMS). A group of workers in this path is considered a critical group, but there are no conviction on this classification, because there are not measurements available. Thus, workers claiming for occupationally exposed individual's (OEI) rights are common. Employers are always in a complex situation, because if they decided to undertake the individual external monitoring of the critical working groups, the Court considers all as OEI and employers are taxed. On the other hand, if they do not provide monitoring, it is impossible to prove that these workers were not exposed to effective doses higher than individual annual public's limit and they lose the actions, too. This work proposes a methodology to evaluate, using TLD environmental monitors, air kerma rate at critical staff points in a NMS. This method provides relevant information about critical groups' exposure. From these results, the clinic or hospital may prove technically, without individual monitoring of employees, the classification of areas and can estimate the maximum flow of patients in the free areas which guarantees exposures below the public individual dose limit. This methodology has been applied successfully to a private clinic in Rio de Janeiro, which operates a NMS. The only critical group that received exposure statistically different from clinic background radiation was that on the antechamber of the NMS. This is a site that should be characterized as a supervised area and the group of workers in this environment as OEI, as the estimated extrapolated annual effective dose in this position was 1.2 +- 0.7 mSv/year, above the public annual limit (1,0 mSv/year).

    2011-01-01

    Services usually have a limited life under modern conditions of competition. The life cycle phenomenon is characterized by time-varying demand and a learning curve of workforce efficiency, making it difficult to determine staffing requirements. This paper initiates a study of the service life cycle phenomenon, from which the learning curve is found to be manageable through workforce planning. Therefore, optimal control is employed to model workforce planning over a service life cycle. An iter...

  2. HEALTHCARE: A COMPLEX SERVICE SYSTEM

    Institute of Scientific and Technical Information of China (English)

    James M. TIEN; Pascal J. GOLDSCHMIDT-CLERMONT

    2009-01-01

    Healthcare is indeed a complex service system, one requiring the technobiology approach of systems engineering to underpin its development as an integrated and adaptive system. In general, healthcare services are carried out with knowledge-intensive agents or components which work together as providers and consumers to create or co-produce value. Indeed, the engineering design of a healthcare system must recognize the fact that it is actually a complex integration of human-centered activities that is increasingly dependent on information technology and knowledge. Like any service system, healthcare can be considered to be a combination or recombination of three essential components-people (characterized by behaviors, values, knowledge, etc.), processes (characterized by collaboration, customization, etc.) and products (characterized by software, hardware, infrastructures, etc.). Thus, a healthcare system is an integrated and adaptive set of people, processes and products. It is, in essence, a system of systems which objectives are to enhance its efficiency (leading to greater interdependency) and effectiveness (leading to improved health). Integration occurs over the physical, temporal, organizational and functional dimensions, while adaptation occurs over the monitoring, feedback, cybernetic and learning dimensions. In sum, such service systems as healthcare are indeed complex, especially due to the uncertainties associated with the human-centered aspects of these systems. Moreover, the system complexities can only be dealt with methods that enhance system integration and adaptation.

    Service Oriented Architectures (SOAs) are component-based architectures, characterized by reusability, modularization and composition, usually offered by HTTP (web services) and often equipped with a Quality of Services (QoS) measure. In order to guarantee the fairness property to each client requesting a service, we propose a fair version of the (Soft) Concurrent Constraint language to deal with the negotiation phases of the Service Level Agreement (SLA) protocol.

  5. From theoretical to actual ecosystem services: mapping beneficiaries and spatial flows in ecosystem service assessments

    Directory of Open Access Journals (Sweden)

    Kenneth J. Bagstad

    2014-06-01

    Full Text Available Ecosystem services mapping and modeling has focused more on supply than demand, until recently. Whereas the potential provision of economic benefits from ecosystems to people is often quantified through ecological production functions, the use of and demand for ecosystem services has received less attention, as have the spatial flows of services from ecosystems to people. However, new modeling approaches that map and quantify service-specific sources (ecosystem capacity to provide a service, sinks (biophysical or anthropogenic features that deplete or alter service flows, users (user locations and level of demand, and spatial flows can provide a more complete understanding of ecosystem services. Through a case study in Puget Sound, Washington State, USA, we quantify and differentiate between the theoretical or in situ provision of services, i.e., ecosystems' capacity to supply services, and their actual provision when accounting for the location of beneficiaries and the spatial connections that mediate service flows between people and ecosystems. Our analysis includes five ecosystem services: carbon sequestration and storage, riverine flood regulation, sediment regulation for reservoirs, open space proximity, and scenic viewsheds. Each ecosystem service is characterized by different beneficiary groups and means of service flow. Using the ARtificial Intelligence for Ecosystem Services (ARIES methodology we map service supply, demand, and flow, extending on simpler approaches used by past studies to map service provision and use. With the exception of the carbon sequestration service, regions that actually provided services to people, i.e., connected to beneficiaries via flow paths, amounted to 16-66% of those theoretically capable of supplying services, i.e., all ecosystems across the landscape. These results offer a more complete understanding of the spatial dynamics of ecosystem services and their effects, and may provide a sounder basis for

  6. Characterization of nanoscale clusters fabricated by pulsed laser irradiation of thin Au films

    International Nuclear Information System (INIS)

    The characterization of Au nanoclusters (AuNCs) on indium-tin-oxide (ITO) substrates fabricated by nanosecond pulsed laser irradiations of thin Au films is reported. By several hundreds of pulsed laser irradiations of 2.5 × 107 W cm−2 and 5 × 107 W cm−2 intensity in 1 min, the nanoscale clusters are formed in an ultrafast melting, collecting, growing-up and solidification process of 5, 7.5 and 10 nm Au films. The mean diameter and size distribution of nanoclusters are quantified by the statistical analysis on scanning electron microscopy (SEM) images. The melt dynamics and temperature changes of Au film under pulsed laser irradiation are obtained by quantitative evaluation. The extinction spectra of the initial Au films and formed Au nanoclusters on the ITO surface have also been measured. It has been found that the mean diameter, the surface density and extinction spectra of the induced AuNCs are influenced by the thickness of Au films and the laser intensity. The evolutional mechanism of the nanoscale clusters formation is discussed by the comparison on the morphology of the Au films with and without laser irradiations.

  13. Managing service excellence. Internal customer service training

    International Nuclear Information System (INIS)

    WHO ARE OUR CUSTOMERS? Electric Users, regulators, vendors, suppliers, or our own employees? The answer is ALL exclamation point They are all customers. Regardless if they are external or internal customers, one must focus on quality of service delivery in order to maintain customer satisfaction. The most successful companies are quickly realizing that managing SERVICE EX NCE is our only future. For the next decade, the issue of service quality will exceed the issue of productivity. It is very easy to see that the business behind a utility is serving our electric consumers. However, internal customer service - service excellence to employees inside a company is the foundation for success. This paper describes a training program that is being implemented across Duke Power for employees on internal customer service. How we provide service to each other within a company impacts service quality to our external customers. This training refocuses behaviors and perceptions so to concentrate on quality service delivery to our internal customers - our employees. We all have positive and negative experiences with obtaining quality service by either external organizations or internal employees. Therefore, we start with a common foundation. Whether it be a supplier, vendor, or a station administrative group, we have experienced either excellent or poor customer service. All of us have potential in managing the delivery of excellent customer service. However, many of us may need new perspectives so to add depth with which we view and manage service excellence to our internal customers

    The thermal and light-induced spin transitions in [Fe{sub x}Zn{sub 1-x}(Phen){sub 2}(NCS){sub 2}] (Phen = 1,10-phenantholine) have been investigated by magnetic susceptibility, photomagnetism and diffuse reflectivity measurements. These complexes display a thermal spin transition and undergo the light-induced excited spin state trapping (LIESST) effect at low temperatures. For each compound, the thermal spin transition temperature, T{sub 1/2}, and the relaxation temperature of the photo-induced high-spin state, T(LIESST), have been systematically determined. It appears that T{sub 1/2} decreases with the metal dilution while T(LIESST) remains unchanged. This behaviour is discussed on the basis of the kinetic study performed by combining the use of SQUID magnetometer, up to the T(LIESST) value, and the dynamic diffuse reflectivity setup, from the T(LIESST) temperature up to the thermal spin transition.

Size and depth distributions as well as structural disorder in the NCs were measured by RBS, TEM, SAXS and EXAFS. The EXAFS results show that the embedded Ge NCs are rendered amorphous at fluences {approx}40 times lower than bulk crystalline Ge (c-Ge). No significant changes in the size or depth distribution of the NCs are observed for all irradiation fluences. Compared to c-Ge, the higher-energy structural state of the NCs prior to irradiation and the presence of the nanocrystal/matrix interface are considered the main causes for the peculiar amorphisation behavior of embedded Ge NCs.

    The details of syntheses, characterizations and structures of cadmium(II) and zinc(II) pseudohalide complexes of the types (M(L)(NCS)2), (M(L)(N3)PF6, (Zn(L)(NCO)PF6 and (Cd(L)(NCO)2)(PF6)2 (1-6) (M = CdII and ZnII; L = N,N-bis(3,5-dimethylpyrazol-1-ylmethyl)aminomethylpyridine) are described. All the complexes are characterized using their spectroscopic and other physicochemical results. Crystal structures of (Cd(L)(NCO))2(PF6)2 (3) and (Zn(L)(N3))PF6 (5) have been solved by single crystal X-ray diffraction measurements. Each metal center in binuclear compound 3 has double NCO- bridged distorted octahedral structure whereas in mononuclear compound 5 adopts a distorted trigonal bipyramidal geometry. (author)

    2015-01-01

    Governments face a fundamental choice between in-house production and contracting out for the delivery of services to citizens. This article examines the importance of ideology, fiscal pressure, and size for contracting out in technical and social services. The analysis builds on a panel data set...... covering municipal spending on services in all 98 Danish municipalities. The authors find that contracting out is shaped by ideology in social services but not in technical services, which indicates that social services are the contemporary ideological battlefield of privatization. The analysis further...... reveals that economically prosperous municipalities are more likely to contract out social services, whereas contracting out of technical services is not influenced by economic affluence. Finally, larger municipalities contract out more in technical services but less in social services, demonstrating that...

  6. Essentials Of Service Design

    Directory of Open Access Journals (Sweden)

    Harry Katzan, Jr.

    2011-11-01

    Full Text Available This paper is a conspectus of service design for service scientists. Historically, science has been concerned with the discovery and study of natural and socially developed phenomena, and the role of design has been to create new artifacts and processes and to improve existing ones. Service has been an important part of the fabric of societal culture from ancient times, so the notion of service as the co-creation of value by provider and client is well established. It necessarily follows that the objective of service design is to add value by enhancing the efficiency, effectiveness, and efficacy of older service systems and to create newer ones with requisite attributes. This is a topic that has not been covered in traditional service science research. Thus, service design, as a discipline, seeks to facilitate the operation of the modern global economy that is now based on service. The necessary elements of service design are introduced and important concepts are identified.

  12. Qbox-Services: Towards a Service-Oriented Quality Platform

    Science.gov (United States)

    González, Laura; Peralta, Verónika; Bouzeghoub, Mokrane; Ruggia, Raúl

    The data quality market is characterized by a sparse offer of tools, providing individual functionalities which have their own interest with respect to quality assessment. But interoperating among these tools remains a technical challenge because of the heterogeneity of their models and access patterns. On the other side, quality analysts require more and more integration facilities that allow them to consolidate and aggregate multiple quality measures acquired from different observations. The QBox platform, developed within the ANR Quadris project, aims at filling this gap by supplying a service-based integration infrastructure that allows interoperability among several quality tools and provides an OLAP-based quality model to support multidimensional analysis. This paper focuses on the architectural principles of this infrastructure and illustrates its use through specific examples of quality services.

    Full Text Available The healthcare enterprises are very disconnected. This paper intends to propose a solution that will provide citizens, businesses and medical enterprises with improved access to medical virtual public services. Referred medical services are based on existing national medical Web services and which support medically required services provided by physicians and supplementary health care practitioners, laboratory services and diagnostic procedures, clinics and hospitals’ services. Requirements and specific rules of these medical services are considered, and personalization of user preferences will to be supported. The architecture is based on adaptable process management technologies, allowing for virtual services which are dynamically combined from existing national medical services. In this way, a comprehensive workflow process is set up, allowing for service-level agreements, an audit trail and explanation of the process to the end user. The process engine operates on top of a virtual repository, providing a high-level semantic view of information retrieved from heterogeneous information sources, such as national sources of medical services. The system relies on a security framework to ensure all high-level security requirements are met. System’s architecture is business oriented: it focuses on Service Oriented Architecture - SOA concepts, asynchronously combining Web services, Business Process Management – BPM rules and BPEL standards.

    Ruthenium sensitizers of the type trans-[Ru(L(1))(X)(2)], trans-[Ru(L(2))(X)(2)], trans-[Ru(L(3))(X)(2)], and trans-[Ru(L(4))(X)(2)] (where L(1) = 6,6'-bis(1-H-benzimidazol-2-yl)-4,4'-bis(methoxycarbonyl)-2,2'-bipyridine, L(2) = 4,4' "-bis(tert-butyl)-4',4' '-bis[p-(methoxycarbonyl)phenyl]-2,2':6',2' ':6' ',2' "-quaterpyridine, L(3) = 4',4' '-bis[3,4-(dimethoxy)phenyl]-2,2':6',2' ':6' ',2' "-quaterpyridine, and L(4) = 4',4' '-diethoxycarbonyl-2,2':6',2' ':6' ',2' "-quaterpyridine; X = Cl(-), NCS(-)) were synthesized and characterized by CV, NMR, and UV-vis absorption and emission spectroscopy. The trans-dichloro and dithiocyanate complexes show MLCT transitions in the entire visible and near-IR region. The lowest energy metal-to-ligand charge-transfer transition band of the trans-dichloro complexes is around 14 300 cm(-1) in DMF solution, and these complexes show weak and broad emission signals with onset at above 10 500 cm(-1). The absorption and emission maxima of the trans-dithiocyanate complexes are blue-shifted compared to those of its trans-dichloro analogues because of the strong pi acceptor property of the NCS(-) compared to the Cl(-). The electronic spectra of trans-[Ru(L)(X)(2)] complexes were calculated by INDO/S and compared with the experimental data. The extent of mixing between metal 4d and ligand pi orbitals is discussed. Extensive pi-back-donation is observed. The panchromatic response of these novel complexes renders them as suitable sensitizers for solar energy conversion applications based on titanium dioxide mesoporous electrodes. Preliminary results using the trans-[Ru(L(4))(NCS)(2)] complex show 75% incident photon-to-current efficiencies (IPCE), yielding 18 mA/cm(2) current density under standard AM 1.5 sunlight.

    2014-12-01

    Full Text Available This article describes the issues associated with functioning of contemporary seaport services markets. The growth of international supply chains, technical progress and the integration processes in shipping, growth of containerization, increasing competition in the seaport services markets and environmental protection regulations make it necessary for port service providers to adapt to the changing expectations and requirements of their customers, both shippers and, especially maritime, carriers. Thus, the activities they undertake are associated with making investments to ensure an adequate capacity to handle cargo, passengers and means of transport, required quality of service, but also with appropriate organization of port supply centres and lead to an improvement of their competitiveness. Both the factors associated with the external and internal environment of seaports affect the changes in the relationship between the supply and demand on port services markets.

    2016-07-01

    Efforts to ensure effective participation of patients in healthcare are called by many names-patient centredness, patient engagement, patient experience. Improvement initiatives in this domain often resemble the efforts of manufacturers to engage consumers in designing and marketing products. Services, however, are fundamentally different than products; unlike goods, services are always 'coproduced'. Failure to recognise this unique character of a service and its implications may limit our success in partnering with patients to improve health care. We trace a partial history of the coproduction concept, present a model of healthcare service coproduction and explore its application as a design principle in three healthcare service delivery innovations. We use the principle to examine the roles, relationships and aims of this interdependent work. We explore the principle's implications and challenges for health professional development, for service delivery system design and for understanding and measuring benefit in healthcare services.

    2014-01-01

    Virtually all nontrivial and modern service related problems and systems involve data volumes and types that clearly fall into what is presently meant as "big data", that is, are huge, heterogeneous, complex, distributed, etc. Data mining is a series of processes which include collecting and accumulating data, modeling phenomena, and discovering new information, and it is one of the most important steps to scientific analysis of the processes of services.  Data mining application in services requires a thorough understanding of the characteristics of each service and knowledge of the compatibility of data mining technology within each particular service, rather than knowledge only in calculation speed and prediction accuracy. Varied examples of services provided in this book will help readers understand the relation between services and data mining technology. This book is intended to stimulate interest among researchers and practitioners in the relation between data mining technology and its application to ...

  1. Focusing on customer service.

    Science.gov (United States)

    1996-01-01

    This booklet is devoted to a consideration of how good customer service in family planning programs can generate demand for products and services, bring customers back, and reduce costs. Customer service is defined as increasing client satisfaction through continuous concern for client preferences, staff accountability to clients, and respect for the rights of clients. Issues discussed include the introduction of a customer service approach and gaining staff commitment. The experience of PROSALUD in Bolivia in recruiting appropriate staff, supervising staff, soliciting client feedback, and marketing services is offered as an example of a successful customer service approach. The key customer service functions are described as 1) establishing a welcoming atmosphere, 2) streamlining client flow, 3) personalizing client services, and 4) organizing and providing clear information to clients. The role of the manager in developing procedures is explored, and the COPE (Client-Oriented Provider-Efficient) process is presented as a good way to begin to make improvements. Techniques in staff training in customer service include brainstorming, role playing, using case studies (examples of which are provided), and engaging in practice sessions. Training also leads to the development of effective customer service attitudes, and the differences between these and organizational/staff-focused attitudes are illustrated in a chart. The use of communication skills (asking open-ended questions, helping clients express their concerns, engaging in active listening, and handling difficult situations) is considered. Good recovery skills are important when things go wrong. Gathering and using client feedback is the next topic considered. This involves identifying, recording, and discussing customer service issues as well as taking action on these issues and evaluating the results. The booklet ends by providing a sample of customer service indicators, considering the maintenance of a

  2. Transducer characterization

    International Nuclear Information System (INIS)

    For inservice inspection transducer characterization can be an important item if one wants to compare ultrasonic examination data obtained at different times (fingerprint). It is possible that the transducers used during previous examinations are lost or will become defect. In such a case it is most useful if one can check the characteristics of the replacement transducers. Some time ago an elegant characterization method was developed by the EURATOM Joint Research Centre of Ispra based on liquid crystals. This method is now under development at Neratoom and the results so far indicate that a robust characterization rig can be built at a reasonable price

    RAMESH KUMAR

    2006-09-01

    Full Text Available Divalent cobalt, nickel and copper salts reacted in situ with 3-aminopyridine and biacetyl to form complexes of the type: [M(Ap2biac2X2], where Ap2biac is the ligand and X=Cl, Br, NO3 or NCS. The complexes were analysed and characterized as distorted octahedral by conductance, molecular weight, magnetic, electronic and IR spectral studies. The electronic spectra were interpreted and tentative aassignments made. The infrared spectral studies revealed that two molecules of 3-aminopyridine were joined by molecules of biacetyl through a two carbon atom bridge and that the ligand coordinated through azomethine nitrogen atoms, whereas the pyridine nitrogen does not participate in the coordination. In the far infrared spectra, various metal–ligand vibrations were observed and are discussed.

  6. The Semantics of Web Services: An Examination in GIScience Applications

    Directory of Open Access Journals (Sweden)

    Xuan Shi

    2013-09-01

    Full Text Available Web service is a technological solution for software interoperability that supports the seamless integration of diverse applications. In the vision of web service architecture, web services are described by the Web Service Description Language (WSDL, discovered through Universal Description, Discovery and Integration (UDDI and communicate by the Simple Object Access Protocol (SOAP. Such a divination has never been fully accomplished yet. Although it was criticized that WSDL only has a syntactic definition of web services, but was not semantic, prior initiatives in semantic web services did not establish a correct methodology to resolve the problem. This paper examines the distinction and relationship between the syntactic and semantic definitions for web services that characterize different purposes in service computation. Further, this paper proposes that the semantics of web service are neutral and independent from the service interface definition, data types and platform. Such a conclusion can be a universal law in software engineering and service computing. Several use cases in the GIScience application are examined in this paper, while the formalization of geospatial services needs to be constructed by the GIScience community towards a comprehensive ontology of the conceptual definitions and relationships for geospatial computation. Advancements in semantic web services research will happen in domain science applications.

    International Nuclear Information System (INIS)

    Niagara Mohawk supports efforts to deregulate the natural gas industry. Competition has existed in the gas industry for some time and it is here to stay. While increased competition can benefit all customers, transition to more fully deregulated markets will create winners and losers. Niagara Mohawk intends to focus on the opportunities and be a winner. Unbundled transportation service has been offered for about seven years and a form of no notice services for two and one half years. Last year we were the first to introduce capacity brokering service in New York. We plan to work with the NYS Public Service Commission to offer an expanded menu of additional gas services to industrial customers. We're looking at doing this within the regulatory framework thereby capturing benefits for the firm ratepayer while avoiding the duplication and added expense of an independent marketing entity. The services that Niagara Mohawk plans to offer its customers are described

    2011-03-01

    We lend theoretical insight to the service climate literature by exploring the joint effects of branch service climate and the internal service provided to the branch (the service received from corporate units to support external service delivery) on customer-rated service quality. We hypothesized that service climate is related to service quality most strongly when the internal service quality received is high, providing front-line employees with the capability to deliver what the service climate motivates them to do. We studied 619 employees and 1,973 customers in 36 retail branches of a bank. We aggregated employee perceptions of the internal service quality received from corporate units and the local service climate and external customer perceptions of service quality to the branch level of analysis. Findings were consistent with the hypothesis that high-quality internal service is necessary for branch service climate to yield superior external customer service quality. PMID:21142340

It analyzes care activities and strategies, the profile of the teams, the conditions of installations, equipment and supplies, integrated care and registration services and the opinion of health managers with respect to the needs and requirements for a better care to the victims. The sample is composed by 103 services: 34 from Recife, 25 from Rio de Janeiro, 18 from Manaus, 18 from Curitiba and 8 from Brasília. The still preliminary results indicate: lower number of services focusing on the elderly; scarce investment in preventive actions; the principal actions carried out are social assistance, ambulatory and hospital care and psychological assistance; patients received from Basic Health Units require attention of the communities and families; need for investment in capacity building programs for professionals; precarious registries, data handled manually. The wording of the National Policy for Reduction of Morbidity and Mortality from Accidents and Violence is not well-known and there is a lack of articulation among and inside sectors and between prehospital and emergency care services.

  11. Service quality concept and measurement in the business consulting market

    Directory of Open Access Journals (Sweden)

    Dragan Benazić

    2012-07-01

    Full Text Available Service quality is a key factor of the competitive capability of business consulting services providers – it helps strengthen the image, create references, establish long-term business relationships and reduce the perceived risk to the customer of such services. The existing service quality models are not suitable for application to the business-to-business (B2B market due to differences in service characteristics and specific behavior of B2B customers. Business consulting services are highly intangible and complex to evaluate, with a large number of people involved generally both in their provision and use. Typically, they are implemented in the form of a project, characterized by a high degree of interaction between service providers and customers, who differ by their ability to be integrated in their service provision process. It is essential to adapt these services to specific customer needs, and the outcome of service provision may sometimes only be apparent a while after the consulting project has been completed. Therefore, there is no single, generally accepted model of conceptualizing and measuring the quality of B2B services such as business consulting services. Building from existing theoretical notions, the paper determines the suitability of Donabedian's service quality model for conceptualizing and measuring the perceived quality of business consulting services. Based on the results of the empirical research conducted on a sample of 110 managers of the companies which use them, the perceived quality of business consulting services was found to be a multidimensional construct of a higher order which is perceived by customers through such dimensions as service potential, process and results. Thus, the preliminary hypothesis of the paper was confirmed. Research results provide the basis for recommendations to be presented for use by the marketing management of consulting services providers as well as serving as suggestions for future

    2014-01-01

    Research on ecosystem services mapping and valuing has increased significantly in recent years. However, compared to provisioning and regulating services, cultural ecosystem services have not yet been fully integrated into operational frameworks. One reason for this is that transdisciplinarity is...... required to address the issue, since by definition cultural services (encompassing physical, intellectual, spiritual interactions with biota) need to be analysed from multiple perspectives (i.e. ecological, social, behavioural). A second reason is the lack of data for large-scale assessments, as detailed...... surveys are a main source of information. Among cultural ecosystem services, assessment of outdoor recreation can be based on a large pool of literature developed mostly in social and medical science, and landscape and ecology studies. This paper presents a methodology to include recreation in the...

  16. DIRAC distributed computing services

    International Nuclear Information System (INIS)

    DIRAC Project provides a general-purpose framework for building distributed computing systems. It is used now in several HEP and astrophysics experiments as well as for user communities in other scientific domains. There is a large interest from smaller user communities to have a simple tool like DIRAC for accessing grid and other types of distributed computing resources. However, small experiments cannot afford to install and maintain dedicated services. Therefore, several grid infrastructure projects are providing DIRAC services for their respective user communities. These services are used for user tutorials as well as to help porting the applications to the grid for a practical day-to-day work. The services are giving access typically to several grid infrastructures as well as to standalone computing clusters accessible by the target user communities. In the paper we will present the experience of running DIRAC services provided by the France-Grilles NGI and other national grid infrastructure projects.

    1999-11-01

    Recent experiments in DIII-D have investigated internal transport barrier (ITB) formation with neutral beams injected in the counter-current direction, assisted by early ECH during current ramp up. For counter injection the v_torBT term for radial force balance adds to the nabla p term to determine E× B flow shear. Compared to ITB plasmas with co-current injection, characteristics with counter injection at similar beam power are: (a) broader profiles of T_I, T_e, n_e, and ω_tor within a larger barrier radius, (b) reduced profile gradients in the barrier region, and (c) about a factor of 2 higher Z_eff ( ~4) from the carbon impurity. In this paper profile evolution and results of transport analysis will be compared with co-injection plasmas.

    1994-01-01

    A small isolated NASA facility provides assistance to industry in the design, testing, and operation of oxygen systems. White Sands Test Facility (WSTF) was originally established to test rocket propulsion systems for the Apollo program. The facility's role was later expanded into testing characterization, flammability and toxicity characteristics of materials. Its materials and components test methods were adopted by the American society for Testing and Materials. When research and testing results became known, industry requested assistance, and in 1980, NASA authorized WSTF to open its facility to private firms, a valuable service, as oxygen systems testing is often too expensive and too hazardous for many companies. Today, some of the best known American industries utilize White Sands testing capabilities.

    Directory of Open Access Journals (Sweden)

    Stephen G. Kerr

    2011-05-01

    Full Text Available The evolution of a new discipline of service science will creatively disturb the relationship between more established business disciplines.  Each discipline is not an independent silo.  As a result the purpose of this paper was to explore, at this early stage, how the new discipline may create opportunities for interdisciplinary scholarship.  The specific purpose of this paper was to explore how service science might interact with the scholarly and professional practice of accounting.  Accounting practice is dominated by a stewardship proposition.  The stewardship proposition is a problem because typical service science investments will receive unfavorable treatment.  Accounting’s other major proposition is valuation.  Areas of opportunity for positive contributions from a service science approach are discussed.  Service science, as viewed through an accounting lens, will have to find ways to overcome measurement and reporting methods that will not afford service science investments the full benefit of their strategic potential.  Several avenues for research into ways service science can improve accounting scholarship are suggested.

    Full Text Available A big challenge in modern service organization is to focus on customers and to forge their satisfaction and loyalty. Innovation, information technology and value added are decisive factors, however the main aspect to consider is the human factor. It is necessary to focus on people in order to improve the service capability within the organization.Middle manager is the link between the strategy designed by top management and the execution to deliver services, that is realized by employees guided by leaders of middle level. Our study is focused on middle manager service orientation as the pillar to get a customer focus and to forge the service employees' performance.We consider that middle managers have to asume a service leadership in order to foster the productivity and employees' commitment. In that sense we focus especially on middle managers' main roles. Those are the key aspect to deploy a service culture, and at the same time to promote employees' satisfaction that drives their performance and development.

  12. Trusted Translation Services

    Science.gov (United States)

    Atif, Yacine; Serhani, Mohamed Adel; Campbell, Piers; Mathew, Sujith Samuel

    Administering multilingual Web sites and applications reliably, involves interconnected and multipart tasks, where trust in the involved parties and content translation sources is paramount. Published Web sites may reflect content from databases, content management systems and other repositories to manage related Web content. But a Web site mirrored wholly or selectively onto a target language version requires streamlined trusted processes. Traditionally, files are translated and transferred via FTP, e-mail, or other communication means. Similarly, translation instructions are communicated between involved parties through verbal instruction, e-mail, and instruction files lead to a variety of inconsistencies and lack of trust in the translation process. This paper proposes a Web service approach to streamline the translation processes and an integration of trust properties in the proposed translation Web services. Web Services have been instrumental in handling problems inherent to systems integration, allowing web-based systems to converse and communicate data automatically. The OASIS Translation Web Services Technical Committee has released a standard way for Web Services to serve the translation and localization business. This article proposes a framework to centralize translation services at a reputable source providing a workflow and a mechanism to quantify service trust. An implementation of the framework is also described in the context of a localization case study.

    We report the growth and characterization of coexistence of vertically aligned and twinned V-shaped RuO{sub 2} nanorods (NRs). The well-aligned RuO{sub 2} NRs were grown on top of rutile (R) phase TiO{sub 2} NRs sitting on sapphire (SA) (1 0 0) substrate via metal-organic chemical vapor deposition (MOCVD) by using bis(ethylcyclopentadienyl) ruthenium (II) and titanium-tetraisopropoxide (TTIP, Ti[OCH(CH{sub 3}){sub 2}]{sub 4}) as source reagents. The surface morphology, structural, and spectroscopic properties of the as-deposited nanocrystals (NCs) were characterized by field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), micro-Raman spectroscopy, transmission electron microscopy (TEM) and selected-area electron diffractometry (SAED). The FESEM images and XRD patterns indicated growth of vertically aligned RuO{sub 2}(0 0 1) and V-shaped RuO{sub 2}(1 0 1) NRs on top of R-TiO{sub 2} NRs. The Raman spectrum indicated the formation of high quality RuO{sub 2} NCs on rutile phase of TiO{sub 2} NRs. TEM and SAED characterizations of V-shaped RuO{sub 2} NRs showed that the nanorods were crystalline RuO{sub 2} with a twin plane of (1 0 1) and twin direction of [1-bar01] at the V-junction. The probable mechanisms for the formation of well-aligned RuO{sub 2} NRs are discussed.

First, the concept of innovation is defined and second, field literature is reviewed from the perspective of service innovation. The main types of innovation are identified based on several attempts at defining innovation, the most notable being Schumpeter’s. Thus, it is possible to approach concepts such as product and process innovation, incremental and radical innovation. Another aim has been to regard service innovation as a standout type of innovation.

  16. Rethinking Lean Service

    Science.gov (United States)

    Seddon, John; O'Donovan, Brendan; Zokaei, Keivan

    Ever since Levitt's influential Harvard Business Review article 'Production-Line Approach to Service' was published in 1972, it has been common for services to be treated like production lines in both the academic literature and more widely in management practice. The belief that achieving economies of scale will reduce unit costs is a common feature of management decision-making. As technological advancement has produced ever more sophisticated IT and telephony, it has become increasingly easier for firms to standardise and off-shore services. The development of the 'lean' literature has only helped to emphasise the same underlying management assumptions: by managing cost and workers' activity, organisational performance is expected to improve. This chapter argues that through misinterpretation of the core paradigm 'lean' has become subsumed into the 'business as usual' of conventional service management. As a result, 'lean' has become synonymous with 'process efficiency' and the opportunity for significant performance improvement - as exemplified by Toyota - has been missed.

  2. What Are Ecosystem Services?

    OpenAIRE

    Boyd, James; Banzhaf, H. Spencer

    2006-01-01

    This paper advocates consistently defined units of account to measure the contributions of nature to human welfare. We argue that such units have to date not been defined by environmental accounting advocates and that the term “ecosystem services” is too ad hoc to be of practical use in welfare accounting. We propose a definition, rooted in economic principles, of ecosystem service units. A goal of these units is comparability with the definition of conventional goods and services found in GD...

But except for Iceland, the Nordic countries have not followed suit. The article discusses this development within a comparative framework of Public Service...... Broadcasting (PSB) financing regimes in Europe, concluding that Denmark, Finland, Iceland, Norway, and Sweden may still be considered conventional, licence fee PSB countries, but with some interesting differences in relation to competitive and market oriented alternatives of resource provision...

  6. Industrial services at CERN

    CERN Multimedia

    2002-01-01

    The Bulletin looks at industrial services contracts and the real impact of the cost reductions at CERN. The level of industrial services contracts varies from one phase to another. For example, during the dismantling of LEP (photo) it rose substiantially to fall again at the end of dismantling. Industrial services contracts are an important resource for CERN. The level and nature of such contracts changes according to the phase of operation of the Laboratory. A construction phase, as for the LHC, requires a higher level of industrial services contracts compared with a period of normal running. During the operation of LEP, industrial services contracts were thus maintained at a level of 120 MCHF per year. The level rose to 156 MCHF in 2001 to include contracts awarded for dismantling LEP, and fell to about 144 MCHF in 2002 when the dismantling was complete. During the whole LHC construction period, up to 2007, industrial services spending will be stable in the range 135-140 MCHF per year. For the running pe...

    This paper investigates the effect of in-store services on retail food prices, supermarket competition, and demand using fluid milk as a case study. It is shown that higher-service supermarkets charge higher milk prices essentially because of an increase in market power due to differentiation of service offering. Results show that different types of services impact milk prices differently, that upscale food-retailers face stronger competition in newer services, and that service competition re...
