With current and ongoing interest in high temperature gas reactors (HTGRs), the U.S. Nuclear Regulatory Commission (NRC) anticipates the need for nuclear data libraries appropriate for use in applications for modeling, assessing, and analyzing HTGR reactor physics and operating behavior. The objective of this work was to develop a broad-group library suitable for production analyses with SCALE for HTGR applications. Several interim libraries were generated from SCALE fine-group 238- and 999-group libraries, and the final broad-group library was created from Evaluated Nuclear Data File/B Version ENDF/B-VII Release 0 cross-section evaluations using new ORNL methodologies with AMPX, SCALE, and other codes. Furthermore, intermediate resonance (IR) methods were applied to the HTGR broadgroup library, and lambda factors and f-factors were incorporated into the library s nuclear data files. A new version of the SCALE BONAMI module named BONAMI-IR was developed to process the IR data in the new library and, thus, eliminate the need for the CENTRM/PMC modules for resonance selfshielding. This report documents the development of the HTGR broad-group nuclear data library and the results of test and benchmark calculations using the new library with SCALE. The 81-group library is shown to model HTGR cases with similar accuracy to the SCALE 238-group library but with significantly faster computational times due to the reduced number of energy groups and the use of BONAMI-IR instead of BONAMI/CENTRM/PMC for resonance self-shielding calculations.

A multi-group library set named MUSE1.0 with 172-neutron group and 42-photon group is produced based on ENDF/B-VII.0 using NJOY code. Weight function of the multi-group library set is taken from the Vitanim-e library and the max legendre order of scattering matrix is six. All the nuclides have thermal scattering data created using free-gas scattering law and 10 Bondarenko background cross sections se lected to generate the self-shielded multi-group cross sections. The final libraries have GENDF-format, MATXS-format and ACE-multi-group sub-libraries and each sub-library generated under 4 temperatures(293 K,600 K,800 K and 900 K). This paper provides a summary of the procedure to produce the library set and a detail description of the validation of the multi-group library set by several critical benchmark devices and shielding benchmark devices using MCNP code. The ability to handle the thermal neutron transport and resonance self-shielding problems are investigated specially. In the end, we draw the conclusion that the multi-group libraries produced is credible and can be used in the R and D process of Supercritical Water Reactor Design. (authors)

The use of focus groups to determine patron satisfaction with library resources and services is extensive and well established. This article demonstrates how focus groups can also be used to help shape the future direction of a library as part of the strategic planning process. By responding to questions about their long-term library and information needs, focus group participants at the University of Texas Southwestern Medical Center at Dallas Library contributed an abundance of qualitative patron data that was previously lacking from this process. The selection and recruitment of these patrons is discussed along with the line of questioning used in the various focus group sessions. Of special interest is the way the authors utilized these sessions to mobilize and involve the staff in creating the library's strategic plan. This was accomplished not only by having staff members participate in one of the sessions but also by sharing the project's major findings with them and instructing them in how these findings related to the library's future. The authors' experience demonstrates that focus groups are an effective strategic planning tool for libraries and emphasizes the need to share information broadly, if active involvement of the staff is desired in both the development and implementation of the library's strategic plan.

The Divisions of Magnetic Fusion Energy (DMFE) and Reactor Development and Demonstration (DRDD) of the United States Energy Research and Development Administration (ERDA) have jointly sponsored the development of a 171 neutron, 36 gamma ray group pseudo composition independent cross section library based upon ENDF/B-IV. This library (named VITAMIN-C and packaged by RSIC as DLC-41) is intended to be generally applicable to fusion blanket and LMFBR core and shield analysis. The purpose of this paper is to evaluate this library as a possible candidate for specific designation as a ''standard'' in light of American Nuclear Society standards for fine-group cross section data sets. The rationale and qualification procedure for such a standard are discussed. Finally, current limitations and anticipated extensions to this processed data file are described

Pseudo-problem-independent, multigroup cross-section libraries were generated to support Advanced Neutron Source (ANS) Reactor design studies. The ANS is a proposed reactor which would be fueled with highly enriched uranium and cooled with heavy water. The libraries, designated ANSL-V (Advanced Neutron Source Cross Section Libraries based on ENDF/B-V), are data bases in AMPX master format for subsequent generation of problem-dependent cross-sections for use with codes such as KENO, ANISN, XSDRNPM, VENTURE, DOT, DORT, TORT, and MORSE. Included in ANSL-V are 99-group and 39-group neutron, 39-neutron-group 44-gamma-ray-group secondary gamma-ray production (SGRP), 44-group gamma-ray interaction (GRI), and coupled, 39-neutron group 44-gamma-ray group (CNG) cross-section libraries. The neutron and SGRP libraries were generated primarily from ENDF/B-V data; the GRI library was generated from DLC-99/HUGO data, which is recognized as the ENDF/B-V photon interaction data. Modules from the AMPX and NJOY systems were used to process the multigroup data. Validity of selected data from the fine- and broad-group neutron libraries was satisfactorily tested in performance parameter calculations

In this study, multi-group cross section libraries for the DeCART code were generated using a new procedure. The new procedure includes generating the RI tables based on the MC calculations, correcting the effective fission product yield calculations, and considering most of the fission products as resonant nuclides. KAERI (Korea Atomic Energy Research Institute) has developed the transport lattice code KARMA (Kernel Analyzer by Ray-tracing Method for fuel Assembly) and DeCART (Deterministic Core Analysis based on Ray Tracing) for a multi-group neutron transport analysis of light water reactors (LWRs). These codes adopt the method of characteristics (MOC) to solve the multi-group transport equation and resonance fixed source problem, the subgroup and the direct iteration method with resonance integral tables for resonance treatment. With the development of the DeCART and KARMA code, KAERI has established its own library generation system for a multi-group transport calculation. In the KAERI library generation system, the multi-group average cross section and resonance integral (RI) table are generated and edited using PENDF (point-wise ENDF) and GENDF (group-wise ENDF) produced by the NJOY code. The new method does not need additional processing because the MC method can handle any geometry information and material composition. In this study, the new method is applied to the dominant resonance nuclide such as U{sup 235} and U{sup 238} and the conventional method is applied to the minor resonance nuclides. To examine the newly generated multi-group cross section libraries, various benchmark calculations such as pin-cell, FA, and core depletion problem are performed and the results are compared with the reference solutions. Overall, the results by the new method agree well with the reference solution. The new procedure based on the MC method were verified and provided the multi-group library that can be used in the SMR nuclear design analysis.

12G: code for conversion of isotope-ordered cross-section libraries into group-ordered cross-section libraries

International Nuclear Information System (INIS)

Resnik, W.M. II; Bosler, G.E.

1977-09-01

Many current reactor physics codes accept cross-section libraries in an isotope-ordered form, convert them with internal preprocessing routines to a group-ordered form, and then perform calculations using these group-ordered data. Occasionally, because of storage and time limitations, the preprocessing routines in these codes cannot convert very large multigroup isotope-ordered libraries. For this reason, the I2G code, i.e., ISOTXS to GRUPXS, was written to convert externally isotope-ordered cross section libraries in the standard file format called ISOTXS to group-ordered libraries in the standard format called GRUPXS. This code uses standardized multilevel data management routines which establish a strategy for the efficient conversion of large libraries. The I2G code is exportable contingent on access to, and an intimate familiarization with, the multilevel routines. These routines are machine dependent, and therefore must be provided by the importing facility. 6 figures, 3 tables

Validation of a new 39 neutron group self-shielded library based on the nucleonics analysis of the Lotus fusion-fission hybrid test facility performed with the Monte Carlo code

Pelloni, S.; Cheng, E.T.

1985-02-01

The Swiss LOTUS fusion-fission hybrid test facility was used to investigate the influence of the self-shielding of resonance cross sections on the tritium breeding and on the thorium ratios. Nucleonic analyses were performed using the discrete-ordinates transport codes ANISN and ONEDANT, the surface-flux code SURCU, and the version 3 of the MCNP code for the Li 2 CO 3 and the Li 2 O blanket designs with lead, thorium and beryllium multipliers. Except for the MCNP calculation which bases on the ENDF/B-V files, all nuclear data are generated from the ENDF/B-IV basic library. For the deterministic methods three NJOY group libraries were considered. The first, a 39 neutron group self-shielded library, was generated at EIR. The second bases on the same group structure as the first does and consists of infinitely diluted cross sections. Finally the third library was processed at LANL and consists of coupled 30+12 neutron and gamma groups; these cross sections are not self-shielded. The Monte Carlo analysis bases on a continuous and on a discrete 262 group library from the ENDF/B-V evaluation. It is shown that the results agree well within 3% between the unshielded libraries and between the different transport codes and theories. The self-shielding of resonance cross sections results in a decrease of the thorium capture rate and in an increase of the tritium breeding of about 6%. The remaining computed ratios are not affected by the self-shielding of cross sections. (Auth.)

2017-06-01

Full Text Available Library management using manual system is no longer adequate to handle the workload in the library routines, librarians must use application of library automation. To provide a good working performance, librarians use strategy, competences and certain habits, which are referred to as a ritual performance. The performance of the ritual is the demonstration of competence spontaneously by individuals in dealing with individuals, groups and organizations, which contains elements of personal ritual, the work ritual, social ritual, and organization ritual. The research focuses in the automation based library management in the context of the performance of the ritual. This study used a qualitative approach with case study method. The findings suggest that the personal ritual shows the personal habits of librarians to do their tasks, ritual librarian's work show responsibility towards their duties, social rituals strengthen the emotional connection between librarians and leaders, as well as ritual organizations suggest the involvement of librarians in giving their contribution in decision making. Conclusions of this study shows that the performance of rituals librarian at Depok Public Library gives librarians the skills to implement automation systems in the library management, and reflect the values of responsibility, mutual trust, and mutual respect.   Key words : Library Management, Library Automation, Ritual Performance, Ritual Performance Value

2014-08-01

Full Text Available To gain perspective on the use of tandem mass spectral libraries for identification of toxic cyclic peptides, the new library was built from 263 mass spectra (mainly MS2 spectra of 59 compounds of that group, such as microcystins, amatoxins, and some related compounds. Mass spectra were extracted from the literature or specially acquired on ESI-Q-ToF and MALDI-ToF/ToF tandem instruments. ESI-MS2 product-ion mass spectra appeared to be rather close to MALDI-ToF/ToF fragment spectra which are uncommon for mass spectral libraries. Testing of the library was based on searches where reference spectra were in turn cross-compared. The percentage of 1st rank correct identifications (true positives was 70% in a general case and 88–91% without including knowingly defective (‘one-dimension’ spectra as test ones. The percentage of 88–91% is the principal estimate for the overall performance of this library that can be used in a method of choice for identification of individual cyclopeptides and also for group recognition of individual classes of such peptides. The approach to identification of cyclopeptides based on mass spectral library matching proved to be the most effective for abundant toxins. That was confirmed by analysis of extracts from two cyanobacterial strains.

A new multigroup cross-section library based on ENDF/B-VI data has been produced and tested for light water reactor shielding and reactor pressure vessel dosimetry applications. The broad-group library is designated BUGLE-93. The processing methodology is consistent with ANSI/ANS 6.1.2, since the ENDF data were first processed into a fine-group, ''pseudo problem-independent'' format and then collapsed into the final broad-group format. The fine-group library is designated VITAMIN-B6. An extensive integral data testing effort was also performed. In general, results using the new data show significant improvements relative to earlier ENDF data

New coupled neutron-gamma cross-section libraries have been developed for use in light water reactor (LWR) shielding applications, including pressure vessel dosimetry calculations. The libraries, which were generated using Evaluated Nuclear Data File/B Version VII Release 0 (ENDF/B-VII.0), use the same fine-group and broad-group energy structures as the VITAMIN-B6 and BUGLE-96 libraries. The processing methodology used to generate both libraries is based on the methods used to develop VITAMIN-B6 and BUGLE-96 and is consistent with ANSI/ANS 6.1.2. The ENDF data were first processed into the fine-group pseudo-problem-independent VITAMIN-B7 library and then collapsed into the broad-group BUGLE-B7 library. The VITAMIN-B7 library contains data for 391 nuclides. This represents a significant increase compared to the VITAMIN-B6 library, which contained data for 120 nuclides. The BUGLE-B7 library contains data for the same nuclides as BUGLE-96, and maintains the same numeric IDs for those nuclides. The broad-group data includes nuclides which are infinitely dilute and group collapsed using a concrete weighting spectrum, as well as nuclides which are self-shielded and group collapsed using weighting spectra representative of important regions of LWRs. The verification and validation of the new libraries includes a set of critical benchmark experiments, a set of regression tests that are used to evaluate multigroup crosssection libraries in the SCALE code system, and three pressure vessel dosimetry benchmarks. Results of these tests confirm that the new libraries are appropriate for use in LWR shielding analyses and meet the requirements of Regulatory Guide 1.190.

Template-based combinatorial enumeration of virtual compound libraries for lipids.

Science.gov (United States)

Sud, Manish; Fahy, Eoin; Subramaniam, Shankar

2012-09-25

A variety of software packages are available for the combinatorial enumeration of virtual libraries for small molecules, starting from specifications of core scaffolds with attachments points and lists of R-groups as SMILES or SD files. Although SD files include atomic coordinates for core scaffolds and R-groups, it is not possible to control 2-dimensional (2D) layout of the enumerated structures generated for virtual compound libraries because different packages generate different 2D representations for the same structure. We have developed a software package called LipidMapsTools for the template-based combinatorial enumeration of virtual compound libraries for lipids. Virtual libraries are enumerated for the specified lipid abbreviations using matching lists of pre-defined templates and chain abbreviations, instead of core scaffolds and lists of R-groups provided by the user. 2D structures of the enumerated lipids are drawn in a specific and consistent fashion adhering to the framework for representing lipid structures proposed by the LIPID MAPS consortium. LipidMapsTools is lightweight, relatively fast and contains no external dependencies. It is an open source package and freely available under the terms of the modified BSD license.

The evaluated nuclear data file (ENDF)/B-7.0 v4.1m3 MPACT 47-group library has been used as a main library for the Consortium for Advanced Simulation of Light Water Reactors (CASL) neutronics simulator in simulating pressurized water reactor (PWR) problems. Recent analysis for the high void boiling water reactor (BWR) fuels and burnt fuels indicates that the 47-group library introduces relatively large reactivity bias. Since the 47- group structure does not match with the SCALE 6.2 252-group boundaries, the CASL Virtual Environment for Reactor Applications Core Simulator (VERA-CS) MPACT library must be maintained independently, which causes quality assurance concerns. In order to address this issue, a new 51-group structure has been proposed based on the MPACT 47- g and SCALE 252-g structures. In addition, the new CASL library will include a 19-group structure for gamma production and interaction cross section data based on the SCALE 19- group structure. New AMPX and MPACT 51-group libraries have been developed with the ENDF/B-7.0 and 7.1 evaluated nuclear data. The 19-group gamma data also have been generated for future use, but they are only available on the AMPX 51-g library. In addition, ENDF/B-7.0 and 7.1 MPACT 252-g libraries have been generated for verification purposes. Various benchmark calculations have been performed to verify and validate the newly developed libraries.

The ENEA-Bologna Nuclear Data Group produced the VITJEF22.BOLIB (NEA-1699/01 ZZ VITJEF22.BOLIB) and MATJEF22.BOLIB (NEA-1740/01 ZZ MATJEF22.BOLIB) fine-group coupled neutron and photon (199 n + 42 γ) cross section libraries for nuclear fission applications, respectively in AMPX and MATXS format and based on the JEF-2.2 European nuclear data file. Both the libraries were produced from the same set of cross section files in GENDF format, generated with the NJOY-94.66 nuclear data processing system. The present libraries can be considered as European counterparts of the VITAMIN-B6 (DLC-0184 ZZ VITAMIN-B6) American library in AMPX format, based on the ENDF/B-VI Release 3 American nuclear data file. In fact they have the same general features and the same neutron and photon energy group structures as VITAMIN-B6. In particular, all these libraries are pseudo-problem-independent and based on the Bondarenko (f-factor) method for the treatment of neutron resonance self-shielding and temperature effects. Each ENEA-Bologna library contains a set of 133 nuclide cross section files processed at 4 temperatures (300 K, 600 K, 1000 K and 2100 K) and obtained for the most part with 6 to 8 values of the background cross section σ 0 . Thermal scattering cross sections were processed at all the temperatures available in the JEF-2.2 thermal scattering law data file for 5 additional bound nuclides: H-1 in light water, H-1 in polyethylene, H-2 in heavy water, C in graphite and Be in beryllium metal. Collapsed working libraries of self-shielded cross sections in the formats used by the deterministic transport codes of the DANTSYS and DOORS systems can be generated from VITJEF22.BOLIB and MATJEF22.BOLIB through, respectively, further problem-dependent data processing with the AMPX or SCAMPI nuclear data processing systems and with the TRANSX code.

Full Text Available Objective – To investigate whether Facebook Groups are useful for library marketing.Design – Content analysis of membership and activity of university library-related Facebook Groups.Setting – Two global Facebook Groups, and the Facebook Groups of two academic libraries in the US (Rutgers University and Indiana University, both with populations in excess of 30 000 students.Subjects – A total of 28 Facebook Groups were analyzed.Methods – Facebook global Groups are open to all users, while Groups based in a network (e.g., a university only allow access for those in the network. Therefore, to collect data, theauthor used personal connections to log on to members’ profiles within university networks.The 26 university Groups were selected by searching Facebook for Groups belonging to the two university networks, using the word ‚library.‛ Groups unrelated to library business were discarded. A total of 11 Groups within the Rutgers network were analyzed. Of these, only one was organized by a librarian; the rest were organized by students. From Indiana, 15 Groups were identified, three of which were organized by librarians.In Table 1 (p. 474, all Groups are listed: 2 global Groups and 26 Groups within the two university networks. The author then visited all Groups, read all posts, and recorded the total number of members; status of each member, divided into faculty, staff and students; dates of first and last post; and discussion activity. The author analyzed group activity by keeping a tally of how often each member participated in discussions, as there was no way to see the number of times a member returned. The author also paid special attention to Groups with a large number of staff and faculty members, to gain information about the efforts of librarians to support or start new Groups.Main Results – There were a total of 652 members in the 26 university Groups (mean number of members was 25, ranging from 2 - 176.

To improve the accuracy of the neutron analyses for subcritical system with thermal fission blanket, a coupled neutron and photon (315 n + 42γ) fine-group cross section library HENDL3.0/FG based on ENDF/B-VII, JEFF3.1 and JENDL3.3 was produced by FDS team. In order to test the availability and reliability of the HENDL3.0/FG data library, shielding and critical safety benchmarks were performed with VisualBUS code. The testing results indicated that the discrepancy between calculation and experimental values of nuclear parameters fell in a reasonable range. It showed that the nuclear data library had accuracy and availability. (authors)

A program for calculating group constants on the basis of libraries of evaluated neutron data

International Nuclear Information System (INIS)

Sinitsa, V.V.

1987-01-01

The GRUKON program is designed for processing libraries of evaluated neutron data into group and fine-group (having some 300 groups) microscopic constants. In structure it is a package of applications programs with three basic components: a monitor, a command language and a library of functional modules. The first operative version of the package was restricted to obtaining mid-group non-block cross-sections from evaluated neutron data libraries in the ENDF/B format. This was then used to process other libraries. In the next two versions, cross-section table conversion modules and self-shielding factor calculation modules, respectively, were added to the functions already in the package. Currently, a fourth version of the GRUKON applications program package, for calculation of sub-group parameters, is under preparation. (author)

A P 3 227-neutron-group cross-section library has been processed for the subsequent generation of problem-dependent fine- or broad-group cross sections for a broad range of applications, including shipping cask calculations, general criticality safety analyses, and reactor core and shielding analyses. The energy group structure covers the range 10 -5 eV - 20 MeV, including 79 thermal groups below 3 eV. The 129-material library includes processed data for all materials in the ENDF/B-V General Purpose File, several data sets prepared from LENDL data, hydrogen with water- and polyethyelene-bound thermal kernels, deuterium with C 2 O-bound thermal kernels, carbon with a graphite thermal kernel, a special 1/V data set, and a dose factor data set. The library, which is in AMPX master format, is designated CSRL-V (Criticality Safety Reference Library based on ENDF/B-V data). Also included in CSRL-V is a pointwise total, fission, elastic scattering, and (n,γ) cross-section library containing data sets for all ENDF/B-V resonance materials. Data in the pointwise library were processed with the infinite dilute approximation at a temperature of 296 0 K

The accuracy of radiation damage calculations for the most important LWR component, the reactor pressure vessel (RPV), directly linked with the RPV End-of-Life (EoL) prediction which is in its turn connected with fundamental nuclear safety aspects and relevant economic impacts. In this connection, for nearly ten years the ENEA-Bologna Nuclear Data Group conducts the nuclear data processing and validation activities addressed to update the specialized broad-group coupled neutron/photon working cross section libraries for shielding and radiation damage calculations through NJOY and Bologna revised version of SCAMPI data processing systems. A number of working group-wise data libraries has been prepared and transferred to the ENEA Data Bank for dissemination. Several years ago the NRC ”Kurchatov Institute” has reset the GRUCON project, originally designed to provide group constants for fast nuclear reactor calculations [12], with aim to expand its application area and to use in the WWER safety tasks, in particular, in the RPV radiation damage analyses. By means of updated GRUCON and NJOY-99 processing codes, and calculation procedure, developed in the NDG of ENEA Bologna, a sample of kerma&damage energy point-wise data sub-libraries from different evaluated data libraries has been generated. On the base of this sample, the quantitative assessment of kerma/dpa data precision in the RPV calculations is obtained

Krysl, V.; Mikolas, P.; Svarny, J.

2002-01-01

Paper provides summary of methodology of few-group library preparation with emphasis on new features of assemblies, like fuel assemblies with Gd burnable poison or Control Fuel Assembly with Hf plates. Special attention is devoted to the transient part (coupler) of Control Fuel Assembly from the point of view of boundary conditions preparation. Based of this methodology prepared library is implemented into macro code for different number of axial meshes for both coarse and fine mesh diffusion calculations. Problems with local power peaking calculations in WWER-440 cores are closely connected with the correct modeling of the power perturbations in the neighbourhood of Control Fuel Assembly coupler. The new version of MOBY-DICK provided with the new few group data library can assess most of effects induced by insertion of Control Fuel Assembly in the core including effects of newly designed Hf plates in the coupler of Control Fuel Assembly. Compatibility of transport and diffusion calculation was taken into account in the analysis of Control Fuel Assembly movement without/with Hf plates (Authors)

Endf/B-VII.0 Based Library for Paragon - 313

International Nuclear Information System (INIS)

Huria, H.C.; Kucukboyaci, V.N.; Ouisloumen, M.

2010-01-01

A new 70-group library has been generated for the Westinghouse lattice physics code PARAGON using the ENDF/B-VII.0 nuclear data files. The new library retains the major features of the current library, including the number of energy groups and the reduction in the U-238 resonance integral. The upper bound for the up-scattering effects in the new library, however, has been moved to 4.0 eV from 2.1 eV for better MOX fuel predictions. The new library has been used to analyze standard benchmarks and also to compare the measured and predicted parameters for different types of Westinghouse and Combustion Engineering (CE) type operating reactor cores. Results indicate that the new library will not impact the reactivity, power distribution and the temperature coefficient predictions over a wide range of physics design parameters; however, will improve the MOX core predictions. In other words, the ENDF/B-VI.3 and ENDF/B-VII.0 produce similar results for reactor core calculations. (authors)

2010-11-01

Recent work-hour restrictions and the constantly evolving body of knowledge are challenging the current ways of teaching neurosurgery residents. To develop a curriculum-based digital library of multimedia content to face the challenges in neurosurgery education. We used the residency program curriculum developed by the Congress of Neurological Surgeons to structure the library and Microsoft Sharepoint as the user interface. This project led to the creation of a user-friendly and searchable digital library that could be accessed remotely and throughout the hospital, including the operating rooms. The electronic format allows standardization of the content and transformation of the operating room into a classroom. This in turn facilitates the implementation of a curriculum within the training program and improves teaching efficiency. Future work will focus on evaluating the efficacy of the library as a teaching tool for residents.

Roussin, R.W.; Weisbin, C.R.; White, J.E.; Wright, R.Q.; Greene, N.M.; Ford, W.E. III; Wright, J.B.; Diggs, B.R.

1978-01-01

The Department of Energy (DOE) Division of Magnetic Fusion Energy (DMFE) and Reactor Research and Technology (DRRT) jointly sponsored the development of a coupled, fine-group cross-section library. The 171-neutron, 36-gamma-ray group library is intended to be applicable to fusion reactor neutronics and LMFBR core and shield analysis. Versions of the library are available from the Radiation Shielding Information Center (RSIC) at Oak Ridge National Laboratory in both AMPX and CCCC formats. Computer codes for energy group collapsing, interpolation on Bondarenko factors for resonance self-shielding and temperature corrections, and various other useful data manipulations are available. The experience gained in the utilization of this library is discussed. Indications are that this venture, which is designed to allow users to derive problem-dependent cross sections from a fine-group master library, has been a success

Sargent, C W

1978-01-01

This paper describes the application of zero-base budgeting to libraries and the procedures involved in setting up this type of budget. It describes the "decision packages" necessary when this systmem is employed, as well as how to rank the packages and the problems which are related to the process. Zero-base budgeting involves the entire staff of a library, and the incentive engendered makes for a better and more realistic budget. The paper concludes with the problems which one might encounter in zero-base budgeting and the major benefits of the system. PMID:626795

Mixture-based combinatorial libraries from small individual peptide libraries: a case study on α1-antitrypsin deficiency.

Science.gov (United States)

Chang, Yi-Pin; Chu, Yen-Ho

2014-05-16

The design, synthesis and screening of diversity-oriented peptide libraries using a "libraries from libraries" strategy for the development of inhibitors of α1-antitrypsin deficiency are described. The major buttress of the biochemical approach presented here is the use of well-established solid-phase split-and-mix method for the generation of mixture-based libraries. The combinatorial technique iterative deconvolution was employed for library screening. While molecular diversity is the general consideration of combinatorial libraries, exquisite design through systematic screening of small individual libraries is a prerequisite for effective library screening and can avoid potential problems in some cases. This review will also illustrate how large peptide libraries were designed, as well as how a conformation-sensitive assay was developed based on the mechanism of the conformational disease. Finally, the combinatorially selected peptide inhibitor capable of blocking abnormal protein aggregation will be characterized by biophysical, cellular and computational methods.

International Nuclear Information System (INIS)

Hou, J.; Ivanov, K.; Choi, H.

2012-01-01

New cross section libraries of a neutron transport code MICROX-2 have been generated for advanced reactor design and fuel cycle analyses. A total of 386 nuclides were processed, including 10 thermal scattering nuclides, which are available in ENDF/B-VII release 0 nuclear data. The NJOY system and MICROR code were used to process nuclear data and convert them into MICROX-2 format. The energy group structure of the new library was optimized for both the thermal and fast neutron spectrum reactors based on Contributon and Point-wise Cross Section Driven (CPXSD) method, resulting in a total of 1173 energy groups. A series of lattice cell level benchmark calculations have been performed against both experimental measurements and Monte Carlo calculations for the effective/infinite multiplication factor and reaction rate ratios. The results of MICROX-2 calculation with the new library were consistent with those of 15 reference cases. The average errors of the infinite multiplication factor and reaction rate ratio were 0.31% δk and 1.9%, respectively. The maximum error of reaction rate ratio was 8% for 238 U-to- 235 U fission of ZEBRA lattice against the reference calculation done by MCNP5. (authors)

1 - Description: ORLIBJ32 is a package of the libraries for ORIGEN2 code based on JENDL-3.2(NEA-1642). The one grouped cross section data for PWR and BWR were compiled using the burnup calculation results by SWAT code. The FBR libraries were compiled by the analysis system used at JNC for FBR core calculation. The fission yield and decay constants data were also updated using the second version of the JNDC FP library. In ORLIBJ32, not only one-grouped cross section data but also variable actinide cross section data are prepared, using a code written in FORTRAN77. The routines should be linked to the Original ORIGEN2.1 program. The LWR Libraries are prepared based on the current PWR fuel assembly specification, and the FBR libraries are based on the request by the Japanese FBR researchers. Before compiling the libraries, the specification of fuel assembly was completely reviewed and evaluated by the members of Working Group in the Japanese Nuclear Data Committee, 'working group on the evaluation of the amount of isotope generation'. ORLIBJ33 is a new libraries based on JENDL-3.3 following the release of JENDL-3.3. The parameters used to prepare the library are the same as those of ORLIBJ32. The Original version or ORLIBJ33 is coupled with ORIGEN2.1. But after the release of ORIGEN2.2 from ORNL as CCC-0371 through RSICC, several requests for a combination with ORLIBJ33 and ORIGEN2.2 were received. During the development of ORLIBJ33, released as NEA-1642, authors found a problem in the library maker for FBR libraries, and consequently it was revised and tested in JNC-Oarai. This package 'ORIGEN2.2-UPJ' contains: - updated source code of ORIGEN2.2 of CCC-0371 to use ORLIBJ32 and ORLIBJ33, - all Original libraries in CCC-0371, - ORLIBJ32 in NEA-164/03 (but libraries for FBR are revised), - and ORLIBJ33. In this package, decay data based on the second version of the JNDC FP library and, photon and decay data libraries based on JENDL-3.3 are also included. NLB and NLIB

Optimization of reference library used in content-based medical image retrieval scheme

International Nuclear Information System (INIS)

Park, Sang Cheol; Sukthankar, Rahul; Mummert, Lily; Satyanarayanan, Mahadev; Zheng Bin

2007-01-01

Building an optimal image reference library is a critical step in developing the interactive computer-aided detection and diagnosis (I-CAD) systems of medical images using content-based image retrieval (CBIR) schemes. In this study, the authors conducted two experiments to investigate (1) the relationship between I-CAD performance and size of reference library and (2) a new reference selection strategy to optimize the library and improve I-CAD performance. The authors assembled a reference library that includes 3153 regions of interest (ROI) depicting either malignant masses (1592) or CAD-cued false-positive regions (1561) and an independent testing data set including 200 masses and 200 false-positive regions. A CBIR scheme using a distance-weighted K-nearest neighbor algorithm is applied to retrieve references that are considered similar to the testing sample from the library. The area under receiver operating characteristic curve (A z ) is used as an index to evaluate the I-CAD performance. In the first experiment, the authors systematically increased reference library size and tested I-CAD performance. The result indicates that scheme performance improves initially from A z =0.715 to 0.874 and then plateaus when the library size reaches approximately half of its maximum capacity. In the second experiment, based on the hypothesis that a ROI should be removed if it performs poorly compared to a group of similar ROIs in a large and diverse reference library, the authors applied a new strategy to identify 'poorly effective' references. By removing 174 identified ROIs from the reference library, I-CAD performance significantly increases to A z =0.914 (p<0.01). The study demonstrates that increasing reference library size and removing poorly effective references can significantly improve I-CAD performance

Akie, Hiroshi; Okumura, Keisuke; Takano, Hideki; Ishiguro, Yukio; Kaneko, Kunio.

1992-01-01

Data and functions of the cell burnup calculation of the SRAC system were revised to improve mainly the accuracy of the burnup calculation of high conversion light water reactors (HCLWRs). New burnup chain models were developed in order to treat fission products (FPs) and actinide nuclides in detail. Group cross section library, SRACLIB-JENDL2, was generated based on JENDL-2 nuclear data file. In generating this library, emphasis was placed on FPs and actinides. Also revised were the data such as the average energy release per fission for various actinides. These improved data were verified by performing the burnup analysis of PWR spent fuels. Some new functions were added to the SRAC system for the convenience to yield macroscopic cross sections used in the core burnup process. (author)

Evidence Based Management as a Tool for Special Libraries

Directory of Open Access Journals (Sweden)

Bill Fisher

2007-12-01

Full Text Available Objective ‐ To examine the evidence based management literature, as an example of evidence based practice, and determine how applicable evidence based management might be in the special library environment. Methods ‐ Recent general management literature and the subject‐focused literature of evidence based management were reviewed; likewise recent library/information science management literature and the subject‐focused literature of evidence based librarianshipwere reviewed to identify relevant examples of the introduction and use of evidence based practice in organizations. Searches were conducted in major business/management databases, major library/information science databases, and relevant Web sites, blogs and wikis. Citation searches on key articles and follow‐up searches on cited references were also conducted. Analysis of the retrieved literature was conducted to find similarities and/or differences between the management literature and the library/information scienceliterature, especially as it related to special libraries.Results ‐ The barriers to introducing evidence based management into most organizations were found to apply to many special libraries and are similar to issues involved with evidence based practice in librarianship in general. Despite these barriers, a set of resources to assist special librarians in accessing research‐based information to help them use principles of evidence based management is identified.Conclusion ‐ While most special librarians are faced with a number of barriers to using evidence based management, resources do exist to help overcome these obstacles.

Exponential growth of the mass spectrometry (MS) data is exhibited when the mass spectrometry-based proteomics has been developing rapidly. It is a great challenge to develop some quick, accurate and repeatable methods to identify peptides and proteins. Nowadays, the spectral library searching has become a mature strategy for tandem mass spectra based proteins identification in proteomics, which searches the experiment spectra against a collection of confidently identified MS/MS spectra that have been observed previously, and fully utilizes the abundance in the spectrum, peaks from non-canonical fragment ions, and other features. This review provides an overview of the implement of spectral library search strategy, and two key steps, spectral library construction and spectral library searching comprehensively, and discusses the progress and challenge of the library search strategy.

The sheep (Ovis aries) is favored by many musculoskeletal tissue engineering groups as a large animal model because of its docile temperament and ease of husbandry. The size and weight of sheep are comparable to humans, which allows for the use of implants and fixation devices used in human clinical practice. The construction of a complimentary DNA (cDNA) library can capture the expression of genes in both a tissue- and time-specific manner. cDNA libraries have been a consistent source of gene discovery ever since the technology became commonplace more than three decades ago. Here, we describe the construction of a cDNA library using cells derived from sheep bones based on the pBluescript cDNA kit. Thirty clones were picked at random and sequenced. This led to the identification of a novel gene, C12orf29, which our initial experiments indicate is involved in skeletal biology. We also describe a polymerase chain reaction-based cDNA clone isolation method that allows the isolation of genes of interest from a cDNA library pool. The techniques outlined here can be applied in-house by smaller tissue engineering groups to generate tools for biomolecular research for large preclinical animal studies and highlights the power of standard cDNA library protocols to uncover novel genes.

New WIMS library generation from ENDF/B6 and effect of resonance group structure on cell parameters

International Nuclear Information System (INIS)

Pazirandeh, Ali; Tabesh, Alireza

2002-01-01

Due to inaccessibility to NJOY, steps were taken to create WIMS library, which can be extracted from ENDF/B6 without using NJOY. In addition to using preprocessing codes few programs were written to calculate integral resonance, slowing down power per unit lethargy, potential scattering, and differential scattering cross section, scattering matrices. For neutrons with energy above 4 eV, isotropic elastic scattering was assumed. For neutrons below 4 eV the free gas model was used, except for light elements, which tabulated values of S(α,β) in ENDF/B6 used. The Goldstein-Cohen factors are taken from WIMKAL88.Lib. The integral resonance with self absorption per unit lethargy was obtained from GROUPIE output. The P 1 scattering matrices are calculated only for four elements, namely H, D, C and O at 300 K. In order to examine the created libraries, k eff , δ 28 , ρ 28 , ρ 25 and CR are calculated using new WIMS library, WIMKAL88.Lib and NEA329.Lib. The results showed general agreement. The controversial issue of WIMS library group structure, particularly in resonance region has raised the question of whether the number of resonance group i.e., 13 is optimized. We generated different WIMS libraries consisting of 5, 8, 13, 18 and 23 resonance groups. The main aim was to examine the effect to resonance group structure on calculated core parameters, mainly, k eff , δ 28 , ρ 28 , ρ 25 and CR. These parameters are also calculated and compared with those obtained using WIMKAL88, and NEA329 libraries. (author)

Assessment of nuclear data needs for broad-group SCALE library related to WWER spent fuel applications

International Nuclear Information System (INIS)

Zalesky, K.; Markova, L.

1999-12-01

A preliminary study aimed at the issue of feasibility to generate a broad-group SCALE library related to WWER spent fuel applications was made. The SCALE code system has been installed and is being used in many countries operating WWER-type reactors for criticality and shielding analyses as well as spent fuel isotopic inventory calculations but still without an extensive validation and verification for the WWER environment. This study should be a contribution to QA connected with the SCALE code system application for the WWER calculations as a basis on which the generation of the specific WWER SCALE library can be prepared. Possible ways of the broad-group library development are described. (author)

Rahman, Mafizur; Takano, Hideki

2001-01-01

A new 69-group library of multigroup constants for the lattice code WIMS-D/4 has been generated with an improved resonance treatment, processing nuclear data from JENDL-3.2 by NJOY91.108. A parallel ENDF/B-VI based library has also been constructed for intercomparison of results. Benchmark calculations for a number of thermal reactor critical assemblies of both uranium and plutonium fuels have been performed with the code WIMS-D/4.1 with its three different libraries: the original WIMS library (NEA-0329/10) and the new ENDF/B-VI and JENDL-3.2 based libraries. The results calculated with both ENDF and JENDL based libraries show a similar tendency and are found in better agreement with the experimental values. Benchmark parameters are further calculated with the comprehensive lattice code SRAC95. The results from SRAC95 and WIMS-D/4.1 (both using JENDL-3.2 based libraries) agree well with each other. The new library is also verified for its applicability to mixed-oxide cores of varying plutonium contents

We describe the new version of the Evaluated Nuclear Data File, Endf/B-7.0, of recommended nuclear data for advanced nuclear science and technology applications. The library, produced by the US Cross Section Evaluation Working Group, was released in December 2006. The library contains data in 14 sub-libraries, primarily for reactions with incident neutrons, protons and photons, based on the experimental data and nuclear reaction theory predictions. The neutron reaction sub-library contains data for 393 materials. The new library was extensively tested and shows considerable improvements over the earlier Endf/B-6.8 library. (author)

BUGLE-96: A revised multigroup cross section library for LWR applications based on ENDF/B-VI Release 3

International Nuclear Information System (INIS)

White, J.E.; Ingersoll, D.T.; Slater, C.O.; Roussin, R.W.

1996-01-01

A revised multigroup cross-section library based ON ENDF/B-VI Release 3 has been produced for light water reactor shielding and reactor pressure vessel dosimetry applications. This new broad-group library, which is designated BUGLE-96, represents an improvement over the BUGLE-93 library released in February 1994 and is expected to replace te BUGLE-93 data. The cross-section processing methodology is the same as that used for producing BUGLE-93 and is consistent with ANSI/ANS 6.1.2. As an added feature, cross-section sets having upscatter data for four thermal neutron groups are included in the BUGLE-96 package available from the Radiation Shielding Information Center. The upscattering data should improve the application of this library to the calculation of more accurate thermal fluences, although more computer time will be required. The incorporation of feedback from users has resulted in a data library that addresses a wider spectrum of user needs

Generation of Matxs-formated nuclear data libraries

International Nuclear Information System (INIS)

Vontobel, P.

1989-01-01

Using the NJOY nuclear data processing system, three multigroup MATXS-formated nuclear data libraries were generated based on the European data files JEF-1 and EFF-1. After processing with TRAMIX, TRANSX, or TRANSX-CTR these libraries can be red into most transport and diffusion codes. For the neutron analysis of gas-cooled or water moderated thermal reactor systems (including high converter PWR's) a 70-group WIMS-BOXER structured library was generated. A general purpose fine group library in 308 groups is provided for thermal as well as for fast reactor systems. A coupled 175 neutron/42 photon-group library in VITAMIN-J structure was created for the analysis of shielding problems and fusion blanket design. A problem found when using CRAY's CFT77 compiler to implement NJOY87 is discussed. The problem of irregular selfshielding factors from UNRESR for some isotopes and (σ 0 , material temperature)-combinations in the unresolved resonance range is addressed

Multigroup cross section library; WIMS library

International Nuclear Information System (INIS)

Kannan, Umasankari

2000-01-01

The WIMS library has been extensively used in thermal reactor calculations. This multigroup constants library was originally developed from the UKNDL in the late 60's and has been updated in 1986. This library has been distributed with the WIMS-D code by NEA data bank. The references to WIMS library in literature are the 'old' which is the original as developed by the AEA Winfrith and the 'new' which is the current 1986 WIMS library. IAEA has organised a CRP where a new and fully updated WIMS library will soon be available. This paper gives an overview of the definitions of the group constants that go into any basic nuclear data library used for reactor calculations. This paper also outlines the contents of the WIMS library and some of its shortcomings

Generation of a library of two-group diffusion parameters for SPPS-1,6 by HELIOS

Petkov, P.T.; Haralampieva, C.V.; Simeonov, T.; Stojanova, I.; Kamenov, K.

2000-01-01

The two-group three-dimensional nodal diffusion code SPPS-1.6 has been used for many years for steady-state neutronics calculations of the WWER-440 reactors at Kozloduy NPP. The old library of two-group diffusion parameters for SPPS-1.6 has been generated by WIMSD4 with a nuclear data library compiled from three different libraries. The current paper presents our experience in generating a new library for SPPS-1.6 by the HELIOS lattice code. The accuracy of the current-coupling collision probability (CCCP) method in calculating a single WWER-440 assembly has been studied first. Among all possible angular discretization of the interface partial currents, called coupling orders, only coupling order 3 is suitable for hexagonal cells. Dividing each cell side into 3 segments an accuracy of 100 pcm has been achieved. The accuracy in calculating the absorber problem was estimated at 1%, which means about 10% error in the control assemblies efficiency. The accuracy for small core-reflector problems is 1% as well. The general conclusion is that HELIOS is accurate enough for assembly calculations, but inadequate for absorber and core-reflector problems. (Authors)

2002-01-01

A library of two-group diffusion and kinetics parameters has been generated for the neutron kinetics code DYN3D for analysis of reactivity initiated accidents for the WWER-440 reactors, based on the MAGRU approximation methodology for the diffusion and kinetics parameters. The accuracy of this methodology has been tested and the conclusion is that it is not adequate. A new approximation methodology, based on interpolation for the most widely varying parameters, i.e. the moderator temperature and density, and on approximation for all other independent parameters, is presented. The methodology of calculation of the kinetics parameters using primary data from ENDF-B/VI is described in detail (Authors)

Faced validity evaluated by 10 experts’ viewpoints, then reliability calculated 0.87.Findings of this study are important because of two reasons: first, it provides a comprehensive and an unambiguous vision for recognizing user interfaces’ basic capabilities and characteristics based on social bookmarking. Second, it can provide a base for designing digital libraries in Iran. The results showed that the majority of digital libraries around the world had not used web 2.0 characteristics such as producing, identifying, organizing, and sharing contents except two digital libraries (Google Books, and Ibiblio.

Application of Data Mining in Library-Based Personalized Learning

Directory of Open Access Journals (Sweden)

Lin Luo

2017-12-01

Full Text Available this paper expounds to mine up data with the DBSCAN algorithm in order to help teachers and students find which books they expect in the sea of library. In the first place, the model that DBSCAN algorithm applies in library data miner is proposed, followed by the DBSCAN algorithm improved on demands. In the end, an experiment is cited herein to validate this algorithm. The results show that the book price and the inventory level in the library produce a less impact on the resultant aggregation than the classification of books and the frequency of book borrowings. Library procurers should therefore purchase and subscribe data based on the results from cluster analysis thereby to improve hierarchies and structure distribution of library resources, forging on the library resources to be more scientific and reasonable, while it is also conducive to arousing readers' borrowing interest.

The ENEA-Bologna Nuclear Data Group produced the JEFF-3.1 VITJEFF31.BOLIB and MATJEFF31. BOLIB fine-group coupled neutron and photon (199 n + 42 γ) cross section libraries for nuclear fission applications, respectively in AMPX and MATXS format, with the same specifications and energy group structure of the Endf/B-VI-3 VITAMIN-B6 American library. Each library, containing 181 nuclide cross section files, was generated from the same set of cross section data files in GENDF format, obtained through the Bondarenko (f-factor) method, with an ENEA-Bologna revised version of the GROUPR module of the NJOY-99.160 system. Collapsed working libraries of self-shielded cross sections in FIDO-ANISN format, used by the deterministic transport codes of the DANTSYS and DOORS systems, can be generated from VITJEFF31.BOLIB and MATJEFF31.BOLIB through, respectively, further data processing with an ENEA-Bologna revised version of the SCAMPI system and with the TRANSX code. This paper describes the methodology and specifications of the data processing performed and presents some results of the VITJEFF31.BOLIB validation. (authors)

Structure-Based Virtual Screening of Commercially Available Compound Libraries.

Science.gov (United States)

Kireev, Dmitri

2016-01-01

Virtual screening (VS) is an efficient hit-finding tool. Its distinctive strength is that it allows one to screen compound libraries that are not available in the lab. Moreover, structure-based (SB) VS also enables an understanding of how the hit compounds bind the protein target, thus laying ground work for the rational hit-to-lead progression. SBVS requires a very limited experimental effort and is particularly well suited for academic labs and small biotech companies that, unlike pharmaceutical companies, do not have physical access to quality small-molecule libraries. Here, we describe SBVS of commercial compound libraries for Mer kinase inhibitors. The screening protocol relies on the docking algorithm Glide complemented by a post-docking filter based on structural protein-ligand interaction fingerprints (SPLIF).

The mzQuantML standard has been developed by the Proteomics Standards Initiative for capturing, archiving and exchanging quantitative proteomic data, derived from mass spectrometry. It is a rich XML-based format, capable of representing data about two-dimensional features from LC-MS data, and peptides, proteins or groups of proteins that have been quantified from multiple samples. In this article we report the development of an open source Java-based library of routines for mzQuantML, called the mzqLibrary, and associated software for visualising data called the mzqViewer. The mzqLibrary contains routines for mapping (peptide) identifications on quantified features, inference of protein (group)-level quantification values from peptide-level values, normalisation and basic statistics for differential expression. These routines can be accessed via the command line, via a Java programming interface access or a basic graphical user interface. The mzqLibrary also contains several file format converters, including import converters (to mzQuantML) from OpenMS, Progenesis LC-MS and MaxQuant, and exporters (from mzQuantML) to other standards or useful formats (mzTab, HTML, csv). The mzqViewer contains in-built routines for viewing the tables of data (about features, peptides or proteins), and connects to the R statistical library for more advanced plotting options. The mzqLibrary and mzqViewer packages are available from https://code.google.com/p/mzq-lib/. © 2015 The Authors. PROTEOMICS Published by Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Libraries are grouped into four major types: public, school, academic, and special. The U.S. Geological Survey's (USGS) National Wetlands Research Center (NWRC) library is classified as a special library because it is sponsored by the Federal government, and the collections focus on a specific subject. The NWRC library is the only USGS library dedicated to wetland science. Library personnel offer expert research services to meet the informational needs of NWRC scientists, managers, and support personnel. The NWRC library participates in international cataloging and resource sharing, which allows libraries from throughout the world to borrow from its collections. This sharing facilitates the research of other governmental agencies, universities, and those interested in the study of wetlands.

WIMS-IJSO is a preliminary extended version of the WIMS library as supplied with the CDC version of the S-WIMS-code. It is a result of the feasibility study of the possibility to update and extend the WIMS library. In the course of its preparation valuable experience was gained in understanding the definitions, the conventions and the structure of the WIMS library. This experience will be used in the preparation of an extended WIMS library for some materials from carefully chosen evaluated data. The library as supplied with the WIMS-D4 package will be used as the basis. The materials added to the library had been tested in reactor calculations and their performance was found to be satisfactory. The aim of releasing the preliminary version of the WIMS library is to allow different users to apply the data to various problems

Generation of seven group cross section library for TRIGA LEU fuel in CITATION format and benchmarking some experimental and operational data

2007-01-01

The principal objective of this study is to validate the seven group cross section library in CITATION format for TRIGA LEU Fuel. This presentation deals with the 'generation of a cross section library for the CITATION and its validation. We used WIMSD-5B version for the generation of all group constants. The overall strategy is: (1) use WIMS package to generate few group neutron macroscopic cross section (cell constants) for all of the materials in the core and its immediate neighborhood (2) use 3-D code CITATION to perform the global analysis of the core to study: multiplication factor, neutron flux distribution and power peaking factors. Various options available in WIMS program were studied in depth to finalize the models to generate the most appropriate group constants. For the global analysis the code CITATION and a post processing program FCAP were chosen. Thus a seven group cross section library for the calculations of TRIGA Research Reactor was generated. To investigate the validity of the generated library a critical experiment of the TRIGA research reactor was benchmarked. (author)

So-called few-group neutron data have to be used as input data in core models (such as DYN3D) calculating the reactor behaviour. A survey is given of qualified data libraries for the reactor cores of Russian VVER. The information about primary data used in group data generation and the accuracy reached by the cell codes is compiled in tables. To assess the quality of the data, comparisons have been made between measured and calculated reactor parameters. The information available does not show significant differences concerning the quality of the data libraries. (orig.) [de

ZZ ANSLV, Multigroup Cross Sections Library for ANS Reactor Design Studies

2000-01-01

a proposed reactor which would be fueled with highly enriched uranium and cooled with heavy water. The libraries, designated ANSL-V (Advanced Neutron Source Cross Section Libraries based on ENDF/B-V) are data based in AMPX master format. Although the ANS project was canceled, the libraries are being released because they may be utilized in other applications. ANSL-V data are to be used for the subsequent generation of problem-dependent fine- and/or broad-group cross sections for a wide range of applications, such as core and shield analysis, activation analyses after irradiation of certain elements in the reactor environment, and safety analyses. Problem-dependent cross sections can be derived from the ANSL-V data with AMPX modules included in PSR-0315/AMPX-77, PSR-0352/SCAMPI, or CCC-0545/SCALE-4.3 packages. The derived data libraries in either ANISN or AMPX working library format can be used with codes such as KENO, ANISN, XSDRNPM, DORT, TORT, MORSE. B - Method of solution: ANSL-V consists of the following fine and broad groups: 1. Fine Group (99 energy groups) General Purpose Neutron Library (FGGPN); 2. Broad Group (39 energy groups) General Purpose Neutron Library (BGGPN); 3. Gamma-Ray Interaction (GRI) Library containing data in 44-group gamma-ray structure. 4. Coupled Library containing (CNG) 99-group neutron and 44-group gamma-ray data. 5. Coupled neutron-gamma (CNG) Library containing 39-group, and 44-group gamma-ray data. Neutron and secondary gamma-ray production data in the ANSL-V library were generated primarily from evaluations in the ENDF/B-V General Purpose Library. Where evaluations for specified materials were not available in the ENDF/B-V library, ANSL-V GPN and SGRP data sets were generated from evaluations from other ENDF-formatted libraries. Gamma-ray interaction data sets were generated from evaluations in the ENDF/B-V Photon Interaction Library (DLC-0099/ZZ-HUGO). Because some important materials in the ENDF/B-V library do not have gamma

The TRIPOLI-3 code uses multigroup nuclear data libraries generated using the NJOY-THEMIS suite of modules: for neutrons, they are produced from the ENDF/B-VI evaluations and cover the range between 20 MeV and 10 -5 eV, either in 315 groups and for one temperature, or in 3209 groups and for five temperatures; for gamma-rays, they are from JEF2 and are processed in groups between 14 MeV and keV. The probability tables used for the neutron transport calculations have been derived from the ENDF/B-VI evaluations using the CALENDF code. Cross sections for gamma production by neutron interaction (fission, capture or inelastic scattering) have been derived from ENDF/B-VI in 315 neutron groups and 75 gamma groups. The code also uses two response function libraries: for neutrons; based on several sources, in particular the dosimetry libraries IRDF/85 and IRDF/90; for gamma-rays it is based on the JEF2 evaluation and contains the kerma factors for all the elements and cross sections for all interactions.

The ENEA-Bologna Nuclear Data Group produced the VITJEFF32.BOLIB multi-group coupled neutron/photon (199 n + 42 γ) cross section library in AMPX format, based on the OECD-NEA Data Bank JEFF-3.2 evaluated nuclear data library. VITJEFF32.BOLIB was conceived for nuclear fission applications as European counterpart of the ORNL VITAMIN-B7 similar library (ENDF/B-VII.0 data). VITJEFF32.BOLIB has the same neutron and photon energy group structure as the former ORNL VITAMIN-B6 reference library (ENDF/B-VI.3 data) and was produced using similar data processing methodologies, based on the LANL NJOY-2012.53 nuclear data processing system for the generation of the nuclide cross section data files in GENDF format. Then the ENEA-Bologna 2007 Revision of the ORNL SCAMPI nuclear data processing system was used for the conversion into the AMPX format. VITJEFF32.BOLIB contains processed cross section data files for 190 nuclides, obtained through the Bondarenko (f-factor) method for the treatment of neutron resonance self-shielding and temperature effects. Collapsed working libraries of self-shielded cross sections in FIDO-ANISN format, used by the deterministic transport codes of the ORNL DOORS system, can be generated from VITJEFF32.BOLIB through the cited SCAMPI version. This paper describes the methodology and specifications of the data processing performed and presents some results of the VITJEFF32.BOLIB validation.

Full Text Available This paper examines the methodology and results from Web-based surveys of more than 15,000 networked electronic services users in the United States between July 1998 and June 2003 at four academic health sciences libraries and two large main campus libraries serving a variety of disciplines. A statistically valid methodology for administering simultaneous Web-based and print-based surveys using the random moments sampling technique is discussed and implemented. Results from the Web-based surveys showed that at the four academic health sciences libraries, there were approximately four remote networked electronic services users for each in-house user. This ratio was even higher for faculty, staff, and research fellows at the academic health sciences libraries, where more than five remote users for each in-house user were recorded. At the two main libraries, there were approximately 1.3 remote users for each in-house user of electronic information. Sponsored research (grant funded research accounted for approximately 32% of the networked electronic services activity at the health sciences libraries and 16% at the main campus libraries. Sponsored researchers at the health sciences libraries appeared to use networked electronic services most intensively from on-campus, but not from in the library. The purpose of use for networked electronic resources by patrons within the library is different from the purpose of use of those resources by patrons using the resources remotely. The implications of these results on how librarians reach decisions about networked electronic resources and services are discussed.

Full Text Available The article is aimed at highlighting features of the provision of the fee-based services by library institutions, identifying problems related to the legal and regulatory framework for their calculation, and the methods to implement this. The objective of the study is to develop recommendations to improve the calculation of the fee-based library services. The theoretical foundations have been systematized, the need to develop a Provision for the procedure of the fee-based services by library institutions has been substantiated. Such a Provision would protect library institution from errors in fixing the fee for a paid service and would be an informational source of its explicability. The appropriateness of applying the market pricing law based on demand and supply has been substantiated. The development and improvement of accounting and calculation, taking into consideration both industry-specific and market-based conditions, would optimize the costs and revenues generated by the provision of the fee-based services. In addition, the complex combination of calculation leverages with development of the system of internal accounting together with use of its methodology – provides another equally efficient way of improving the efficiency of library institutions’ activity.

Circulation policies in health science libraries.

Science.gov (United States)

Watkins, C; Coker, N C

1970-10-01

There is general agreement that library policies have considerable influence on the use of libraries. Medical school (health science) libraries of this country were surveyed as to their policies in respect to whether faculty and student use were regulated by a single policy, circulation regulations, hours library was accessible to users, accessibility of reserve material, interlibrary loan, policy on overdue material, and exit control. THE LIBRARIES WERE THEN DIVIDED INTO THREE GROUPS, HIGH, MIDDLE, AND LOW ACCORDING TO THE FOLLOWING CHARACTERISTICS: size of student body, size of faculty, size of holdings, size of library staff, annual budget, and annual circulation. Our findings would indicate that schools falling in a high category based upon these criteria tend to be more restrictive in their policies and to have different regulations for faculty and students than do schools in the low category.These findings warrant further study.

Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are the two most commonly reported sexually transmitted infections (STIs) in the United States (U.S.) and Douglas County, Nebraska has STI rates consistently above the U.S. average. The Douglas County Health Department (DCHD) developed an outreach CT and NG screening program in public libraries to address the problem beyond the traditional STI clinic setting. This study evaluates the effectiveness of the program and identifies factors predictive of CT and NG infections. A retrospective review of surveys of library patrons and DCHD traditional STI clinic clients who submitted urine tests for CT and NG from June 2010 through April 2014 was done. Chi square, Fisher exact, Student's t tests, univariate and multivariate logistic regression were conducted. A total of 977 library records and 4871 DCHD clinic records were reviewed. The percent positive was lower in the library than in the traditional clinic for CT (9.9 vs. 11.2 %) and NG (2.74 vs. 5.3 %) (p = 0.039 and p Library clients were more likely to be 19 years and younger (OR 6.14, 95 % CI: 5.0, 7.5), Black (OR 3.4, 95 % CI: 2.8, 4.1), and asymptomatic (OR 12.4, 95 % CI: 9.9, 15.5) compared to traditional clinic clients. The library STI screening program effectively reaches a younger, asymptomatic, and predominantly Black population compared to a traditional health department clinic site.

The value of Web-based library services at Cedars-Sinai Health System.

Science.gov (United States)

Halub, L P

1999-07-01

Cedars-Sinai Medical Library/Information Center has maintained Web-based services since 1995 on the Cedars-Sinai Health System network. In that time, the librarians have found the provision of Web-based services to be a very worthwhile endeavor. Library users value the services that they access from their desktops because the services save time. They also appreciate being able to access services at their convenience, without restriction by the library's hours of operation. The library values its Web site because it brings increased visibility within the health system, and it enables library staff to expand services when budget restrictions have forced reduced hours of operation. In creating and maintaining the information center Web site, the librarians have learned the following lessons: consider the design carefully; offer what services you can, but weigh the advantages of providing the services against the time required to maintain them; make the content as accessible as possible; promote your Web site; and make friends in other departments, especially information services.

Physicians have difficulty keeping up with new evidence from medical research. We developed the McMaster Premium LiteratUre Service (PLUS), an internet-based addition to an existing digital library, which delivered quality- and relevance-rated medical literature to physicians, matched to their clinical disciplines. We evaluated PLUS in a cluster-randomized trial of 203 participating physicians in Northern Ontario, comparing a Full-Serve version (that included alerts to new articles and a cumulative database of alerts) with a Self-Serve version (that included a passive guide to evidence-based literature). Utilization of the service was the primary trial end-point. Mean logins to the library rose by 0.77 logins/month/user (95% CI 0.43, 1.11) in the Full-Serve group compared with the Self-Serve group. The proportion of Full-Serve participants who utilized the service during each month of the study period showed a sustained increase during the intervention period, with a relative increase of 57% (95% CI 12, 123) compared with the Self-Serve group. There were no differences in these proportions during the baseline period, and following the crossover of the Self-Serve group to Full-Serve, the Self-Serve group's usage became indistinguishable from that of the Full-Serve group (relative difference 4.4 (95% CI -23.7, 43.0). Also during the intervention and crossover periods, measures of self-reported usefulness did not show a difference between the 2 groups. A quality- and relevance-rated online literature service increased the utilization of evidence-based information from a digital library by practicing physicians.

Two broad-group coupled neutron/photon working cross section libraries in FIDO-ANISN format, dedicated to LWR shielding and pressure vessel dosimetry applications, were generated following the methodology recommended by the US ANSI/ANS-6.1.2-1999 (R2009) standard. These libraries, named BUGJEFF311.BOLIB and BUGENDF70.BOLIB, are respectively based on JEFF-3.1.1 and ENDF/B-VII.0 nuclear data and adopt the same broad-group energy structure (47 n + 20 γ) of the ORNL BUGLE-96 similar library. They were respectively obtained from the ENEA-Bologna VITJEFF311.BOLIB and VITENDF70.BOLIB libraries in AMPX format for nuclear fission applications through problem-dependent cross section collapsing with the ENEA-Bologna 2007 revision of the ORNL SCAMPI nuclear data processing system. Both previous libraries are based on the Bondarenko self-shielding factor method and have the same AMPX format and fine-group energy structure (199 n + 42 γ) as the ORNL VITAMIN-B6 similar library from which BUGLE-96 was obtained at ORNL. A synthesis of a preliminary validation of the cited BUGLE-type libraries, performed through 3D fixed source transport calculations with the ORNL TORT-3.2 SN code, is included. The calculations were dedicated to the PCA-Replica 12/13 and VENUS-3 engineering neutron shielding benchmark experiments, specifically conceived to test the accuracy of nuclear data and transport codes in LWR shielding and radiation damage analyses.

The paper provides a review of current practices related to evaluation support services reported by seven biomedical and research libraries. A group of seven libraries from the United States and Canada described their experiences with establishing evaluation support services at their libraries. A questionnaire was distributed among the libraries to elicit information as to program development, service and staffing models, campus partnerships, training, products such as tools and reports, and resources used for evaluation support services. The libraries also reported interesting projects, lessons learned, and future plans. The seven libraries profiled in this paper report a variety of service models in providing evaluation support services to meet the needs of campus stakeholders. The service models range from research center cores, partnerships with research groups, and library programs with staff dedicated to evaluation support services. A variety of products and services were described such as an automated tool to develop rank-based metrics, consultation on appropriate metrics to use for evaluation, customized publication and citation reports, resource guides, classes and training, and others. Implementing these services has allowed the libraries to expand their roles on campus and to contribute more directly to the research missions of their institutions. Libraries can leverage a variety of evaluation support services as an opportunity to successfully meet an array of challenges confronting the biomedical research community, including robust efforts to report and demonstrate tangible and meaningful outcomes of biomedical research and clinical care. These services represent a transformative direction that can be emulated by other biomedical and research libraries.

The JDataViewer is a Java-based charting library developed at CERN, with powerful, extensible and easy to use function editing capabilities. Function edition is heavily used in Control System applications, but poorly supported in products available on the market. The JDataViewer enables adding, removing and modifying function points graphically (using a mouse) or by editing a table of values. Custom edition strategies are supported: developer can specify an algorithm that reacts to the modification of a given point in the function by automatically adapting all other points. The library provides all typical 2D plotting types (scatter, polyline, area, bar, HiLo, contour), as well as data point annotations and data indicators. It also supports common interactors to zoom and move the visible view, or to select and highlight function segments. A clear API is provided to configure and customize all chart elements (colors, fonts, data ranges ...) programmatically, and to integrate non-standard rendering types, inter...

HENDLI1.0 contains one basic evaluated sub-library naming HENDL1.0/E and to processed working sub-libraries naming HENDL1.0/MG and HENDL1.0/MC, respectively. Through carefully comparing, distinguishing and choosing, HENDL1.0/E integrated basic evaluated neutron data files of 213 nuclides from the several main data libraries for evaluated neutron reaction cross sections including ENDF/B-VI (USA), JEF-2.2 (OECD/NEA, Europe), JENDL-3.2 (Japan), CENDL-2 (China), BROND-2 (Russia) and FENDL-2 (IAEA/NDS, ITER program). Based on this, 175-group neutron and 42-group photon neutron-photon coupled multi-group working library HENDL1.0/MG used for discrete ordinate Sn method transport calculation (such as ANISN code) and a compact ENDF form (ACE), continuous energy structure (pointwise) neutron cross section library HENDL1.0/MC for Monte Carlo method transport simulation (as MCMP code) can be attainable with the current group constants processing system NJOY and transport cross section preparation code TRANSX referring to the Vitamin-J energy group structure. In addition, two special bases i.e. transmutation (burnup) library BURNUP. DAT and response function library RESPONSE.DAT, have been also made for fuel cycle calculation and reactivity analyses of nuclear reactor. The relevant sample testing, benchmark checking and primary confirmation are also carried out to assess the validity of multi-purpose data library HENDL1.0. (authors)

These sub-libraries are suitable for deterministic transport and Monte Carlo transport applications, respectively. The SZAs used are the same for the two sub-libraries; that is, the same SZA can be used for both libraries. This makes comparisons between the two libraries and between deterministic and Monte Carlo codes straightforward. Both the multigroup energy and continuous energy libraries were verified and validated with our checking codes checkmg and checkace (multigroup and continuous energy, respectively) Then an expanded suite of tests was used for additional verification and, finally, verified using an extensive suite of critical benchmark models. We feel that this library is suitable for all calculations and is particularly useful for calculations sensitive to temperature effects.

As an activity of the MCNP High-Temperature Library Production Working Group under the Nuclear Code Evaluation Special Committee of Nuclear Code Committee, the automatic editing system for MCNP library 'autonj' was developed. The autonj includes the NJOY-97 code as its main body, and is a system that enables us to easily produce cross section libraries for MCNP from evaluated nuclear data files such as JENDL-3.2. A temperature dependent library at six temperature points based on JENDL-3.2 was produced by using autonj. The autonj system and the temperature dependent library were installed on the JAERI AP3000 computer. (author)

The Internet as a Library-Of-People: For a Cyberethnography of Online Groups

Directory of Open Access Journals (Sweden)

Maurizio Teli

2007-09-01

Full Text Available The concept "cyberethnography" remains undefined in the social sciences while, at the same time, still overlapping too much with the more well-known concept of "virtual ethnography." The aim of our paper is to remedy this situation by underlining new directions in the ethnographic study of computer mediated settings. To do so, we define cyberspace as computer-mediated contexts intrinsically related to supposed-to-be "real" places. From this point of view the ethnography of online groups is not just the ethnography of the groups online (or the online ethnography of groups, but it is both the ethnography of online and related off-line situations, the ethnography of humans and non-human actors in these related fields. It is hybrid, like a cyborg. In a word, it is a cyberethnography. In the first part of the paper, we discuss linkages between classical ethnography and its cyber developments. In the second part, we ground epistemologically the argument in favor of a robust social concept of "cyborg" drawing mainly from the fields called Science, Technology and Society (STS, and Organization Studies (OS. In the third part, we focus our argument on web-based group issues, using field data from our own research to define this kind of group and propose a metaphor, "the Internet as a library-of-people." This metaphor, which is strictly grounded in the cyborg concept, highlights the cyborgic characteristic of society that arises in research practice. URN: urn:nbn:de:0114-fqs0703338

The main characteristics of a P 3 coupled 219-group neutron 36-group gamma-ray library in the AMPX-II Master Interface Format obtained processing ENDF/B-IV data by means of various AMPX-II System modules are presented in this note both for the more reprocessing aspects and features of the generated component files-neutrons, photon and secondary gamma-ray production cross sections. As far as the neutron data are concerned there is the avaibility of 186 data sets regarding most significant fission products. Results of the additional validation of the neutron data pertaining to eighteen benchmark experiments are also given. Some calculational tests on both neutron and coupled data emphasize the important role of the secondary gamma-ray data in nuclear criticality safety calculations

Full Text Available Objective – This article provides an overview of how university libraries research and adapt new cost accounting models, such as “activity-based costing” (ABC and “time-driven activity-based costing” (TDABC, focusing on the strengths and weaknesses of both methods to determine which of these two is suitable for application in university libraries.Methods – This paper reviews and summarizes the literature on cost accounting and costing practices of university libraries. A brief overview of the history of cost accounting, costing, and time and motion studies in libraries is also provided. The ABC and the TDABC method, designed as a revised and easier version of the ABC by Kaplan and Anderson (Kaplan & Anderson 2004 at the beginning of the 21st century, as well as the adoption and adaptation of these methods by university libraries are described, and their strengths and weaknesses, as well as their suitability for university libraries, are analyzed. Results – Cost accounting and costing studies in libraries have a long history, the first of these dating back to 1877. The development of cost accounting and time and motion studies can be seen as a natural evolution of techniques which were created to solve management problems. The ABC method is the best-known management accounting innovation of the last 20 years, and is already widely used in university libraries around the world. However, setting up an ABC system can be very costly, and the system needs to be regularly updated, which further increases its costs. The TDABC system can not only be implemented more quickly (and thus more cheaply, but also can be updated more easily than the traditional ABC, which makes the TDABC the more suitable method for university libraries.Conclusion – Both methods are suitable for university libraries. However, the ABC method can only be implemented in collaboration with an accounting department. The TDABC method can be tested and implemented by

The use of mobile technology in health libraries: a summary of a UK-based survey.

Health libraries have changed over the past fifteen years in the format of the information they provide. This is driven by developments in technology. To conduct a survey of NHS health libraries in the United Kingdom in order to summarise how mobile technologies are being used, how they are promoted and how they are delivered, highlighting good practice and solutions to issues. An online survey was carried out in 2013 and sent to academic and NHS web-based discussion lists. There were 199 responses. Main replies were from large Acute Hospital Trusts. Only 18% of respondents had conducted research into use of mobile technology (MT) within their Trust. Forty per cent of Trusts offered clinical point of care tools, 29% mobile catalogues, and 30% had mobile enabled web sites. Libraries utilised third-party partnerships rather than develop their own applications or tools. Seventy per cent of Trusts promoted new MT services via e-mail. Network restrictions were the main barrier to development as well as finance and expertise. Uptake and development of MT is sporadic and driven by individuals. There is an opportunity for collaboration and sharing resources and expertise. There are benefits to adopting user-friendly resources. © 2015 Health Libraries Group.

This study assessed the book collection of five selected medical libraries in the Philippines, based on Doodys' Essential Purchase List for basic sciences and clinical medicine, to compare the match and non-match titles among libraries, to determine the strong and weak disciplines of each library, and to explore the factors that contributed to the percentage of match and non-match titles. List checking was employed as the method of research. Among the medical libraries, De La Salle Health Sciences Institute and University of Santo Tomas had the highest percentage of match titles, whereas Ateneo School of Medicine and Public Health had the lowest percentage of match titles. University of the Philippines Manila had the highest percentage of near-match titles. De La Salle Health Sciences Institute and University of Santo Tomas had sound medical collections based on Doody's Core Titles. Collectively, the medical libraries shared common collection development priorities, as evidenced by similarities in strong areas. Library budget and the role of the library director in book selection were among the factors that could contribute to a high percentage of match titles.

Generation and validation of the WIMS-D5 library based on JENDL-3.2

International Nuclear Information System (INIS)

Gil, Choong-Sup; Kim, Jung-Do

2002-01-01

A WIMS-D5 library based on JENDL-3.2 has been prepared and is being tested against benchmark problems. Several sensitivity calculations for stability confirmation of the library were carried out, such as fission spectrum dependency and the self-shielding effects of the elastic scattering cross sections and the self-shielding effects 240 Pu and 242 Pu capture cross sections below 4.0 eV. The results of benchmark calculations with the libraries based on JENDL-3.2, ENDF/B-VI.5, JEF-2.2, and the 1986 WIMS-D library were intercompared. The multiplication factors for the thermal lattices are slightly underpredicted by all libraries (up to 1% with ENDF/B-VI.5). The k eff values with the library based on JENDL-3.2 are slightly higher than those of ENDF/B-VI.5 and JEF-2.2. The spectral indices for the lattices with JENDL-3.2 agree with the measured quantities within the uncertainties of the experiments. The calculated amounts of some isotopes such as 149 Sm, 237 Np, 238 Pu, 242 Cm and 243 Cm show large differences from the measured or reference values. (author)

ZZ DECNET-GENDF, Fusion Damage Library of 175 Neutron and 42 Photon VITAMIN-J Groups

International Nuclear Information System (INIS)

1997-01-01

1 - Description of program or function: DECNET is a library for fusion damage computations of 175 neutron + 42 photon VITAMIN-J energy group with the standard weighting function: Maxwellian (at the temperature to which the material is referenced) + 1/E + Fission Spectrum + 1/E + Fusion Peak + 1/E; it includes neutron kerma and gamma-ray production data from radioactive nuclei at 3 temperatures with the same materials of ZZ-GEFF-2-GENDF (see below) from 1-H-1 to Bi-209, mostly taken from EFF-2 with some nuclides from JEF-2.2 - Ag-107, Ag-109, Cd, the 6 Hf isotopes and the 4 W isotopes; however the list of the materials disagrees with that of GEFF-2 in that all elemental nuclides have been split into the components isotopes to follow the respective decay chain and not all materials of GEFF-2 produces nuclei which disintegrate. The library has been produced by the DECKER code which has been developed for this purpose. The format of the library is GENDF. 2 - Method of solution: The library has been produced by the DECKER code developed at ENEA Bologna for this purpose. The code reads the nuclide(s) for which decay kerma and photon production are requested and looks for the necessary data on the RDD (Radioactive Decay Data) file from JEF-2.2

User-focused, User-led: Space Assessment to Transform a Small Academic Library

Directory of Open Access Journals (Sweden)

Christina Hillman

2017-12-01

Full Text Available Abstract Objective – By collecting and analyzing evidence from three data points, researchers sought to understand how library spaces are used. Researchers have used results for evidence based decision making regarding physical library spaces. Methods – Undergraduate researchers, sociology faculty, and librarians used mixed-methods to triangulate findings. Seating sweeps were used to map patrons’ activities in the library. Student-led focus groups discussed patterns of library use, impressions of facilities, and library features and services. The final step included a campus survey developed from seating sweeps and focus group findings. Results – Seating sweeps showed consistent use of the library's main level Learning Commons and upper level quiet spaces; the library’s multipurpose lower level is under-utilized. Students use the main level of the library for collaborative learning, socializing, reading, and computer use. Students use the upper level for quiet study and group work in study rooms. Focus group findings found library use is task-specific. For example, a student may work with classmates on a project using the main level Learning Commons during the day, and then come back at night to use the quiet floor for test preparation. Survey responses highlighted areas in which the library is deficient. For example, respondents cited crowdedness, noise levels, and temperature concerns. Conclusion – These data offer empirical evidence for library space needs. Some data aligns with previous space studies conducted at this library: access to power outlets, lighting, noise, and an outdated environment. Evidence also supports anecdotal concerns of crowding, graduate students lacking designated study space, and the need for quiet study space away from group study space.

2013-01-01

The multi-group transport library MUSE-F1.0 based on ENDF/B-VII.0 with 175-group neutron and 42-group photon was developed by NJOY99. Weighting function is thermal--l/e--fast reactor-fission + fusion, and Legendre order is six. The library was validated by a series of critical and shielding benchmarks. The shielding test involves nuclear data including fission reactor, fusion reactor and accelerator. The result shows that MUSE-F1.0 is suitable for critical and shielding calculation. And it is competent for the application of fast neutron reactor design. (authors)

Development of the adjusted nuclear cross-section library based on JENDL-3.2 for large FBR

International Nuclear Information System (INIS)

Yokoyama, Kenji; Ishikawa, Makoto; Numata, Kazuyuki

1999-04-01

JNC (and PNC) had developed the adjusted nuclear cross-section library in which the results of the JUPITER experiments were reflected. Using this adjusted library, the distinct improvement of the accuracy in nuclear design of FBR cores had been achieved. As a recent research, JNC develops a database of other integral data in addition to the JUPITER experiments, aiming at further improvement for accuracy and reliability. In 1991, the adjusted library based on JENDL-2, JFS-3-J2 (ADJ91R), was developed, and it has been used on the design research for FBR. As an evaluated nuclear library, however, JENDL-3.2 is recently used. Therefore, the authors developed an adjusted library based on JENDL-3.2 which is called JFS-3-J3.2(ADJ98). It is known that the adjusted library based on JENDL-2 overestimated the sodium void reactivity worth by 10-20%. It is expected that the adjusted library based on JENDL-3.2 solve the problem. The adjusted library JFS-3-J3.2(ADJ98) was produced with the same method as the adjusted library JFS-3-J2(ADJ91R) and used more integral parameters of JUPITER experiments than the adjusted library JFS-3-J2(ADJ91R). This report also describes the design accuracy estimation on a 600 MWe class FBR with the adjusted library JFS-3-J3.2(ADJ98). Its main nuclear design parameters (multiplication factor, burn-up reactivity loss, breeding ratio, etc.) except the sodium void reactivity worth which are calculated with the adjusted library JFS-3-J3.2(ADJ98) are almost the same as those predicted with JFS-3-J2(ADJ91R). As for the sodium void reactivity, the adjusted library JFS-3-J3.2(ADJ98) estimates about 4% smaller than the JFS-3-J2(ADJ91R) because of the change of the basic nuclear library from JENDL-2 to JENDL-3.2.

One of the factor that influenced the development of science is the existence of the library, which in this case is the college libraries. Library, which is located in the college environment, aims to supply collections of literatures to support research activities as well as educational for students of the college. Conceptually, every library now starts to practice environmental principles. For example, “X” library as a central library claims to be an environmental friendly library for practicing environmental friendly management, but the X library has not inserted the satisfaction and service aspect to the users, including whether it is true that environmental friendly process is perceived by library users. Satisfaction can be seen from the comparison between expectations and reality of library users. This paper analyzes the level of library user satisfaction with library services in the campus area and the gap between expectations and reality felt by the library users. The result of the research shows that there is a disparity between the hope of library management, which is sustainable and environmentally friendly with the reality in the management of the library, so that it has not given satisfaction to the users yet. The gap value of satisfaction that has the biggest difference is in the library collection with the value of 1.57; while for the smallest gap value is in the same service to all students with a value of 0.67.

Optimal protein library design using recombination or point mutations based on sequence-based scoring functions.

Science.gov (United States)

Pantazes, Robert J; Saraf, Manish C; Maranas, Costas D

2007-08-01

In this paper, we introduce and test two new sequence-based protein scoring systems (i.e. S1, S2) for assessing the likelihood that a given protein hybrid will be functional. By binning together amino acids with similar properties (i.e. volume, hydrophobicity and charge) the scoring systems S1 and S2 allow for the quantification of the severity of mismatched interactions in the hybrids. The S2 scoring system is found to be able to significantly functionally enrich a cytochrome P450 library over other scoring methods. Given this scoring base, we subsequently constructed two separate optimization formulations (i.e. OPTCOMB and OPTOLIGO) for optimally designing protein combinatorial libraries involving recombination or mutations, respectively. Notably, two separate versions of OPTCOMB are generated (i.e. model M1, M2) with the latter allowing for position-dependent parental fragment skipping. Computational benchmarking results demonstrate the efficacy of models OPTCOMB and OPTOLIGO to generate high scoring libraries of a prespecified size.

Process Fragment Libraries for Easier and Faster Development of Process-based Applications

Directory of Open Access Journals (Sweden)

David Schumm

2011-01-01

Full Text Available The term “process fragment” is recently gaining momentum in business process management research. We understand a process fragment as a connected and reusable process structure, which has relaxed completeness and consistency criteria compared to executable processes. We claim that process fragments allow for an easier and faster development of process-based applications. As evidence to this claim we present a process fragment concept and show a sample collection of concrete, real-world process fragments. We present advanced application scenarios for using such fragments in development of process-based applications. Process fragments are typically managed in a repository, forming a process fragment library. On top of a process fragment library from previous work, we discuss the potential impact of using process fragment libraries in cross-enterprise collaboration and application integration.

Developing European Library Services in Changing Times

Directory of Open Access Journals (Sweden)

Paul Ayris

2012-01-01

Full Text Available The purpose of this article is to explain what academic and national libraries can do to continue to offer services and facilities at a time of economic difficulties. It identifies a number of methodologies and opportunities that are open to libraries and takes the view that it is never wise to waste a good crisis, because all threats are really opportunities in disguise. The article looks at the initial economic context for European research libraries and then examines ways in which libraries can tackle the threats which the current financial crisis poses. Joint procurement is one way in which libraries can achieve value for money, and the paper examines the role of JIS C Collections in the UK. Innovation through collaboration and shared services are also ways in which libraries can innovate/make savings in a cost-effective way by sharing the burden of costs around the partnership. The paper gives two examples: one which is now well established, the DART-Europe portal for Open Access e-theses; and one which is in the early stages of being discussed — a cloud-based solution for true collaborative cataloguing amongst the UK’s research and national libraries. The European Research Area (ERA and the contributions that libraries can make to this infrastructure through innovative EU project funding are analysed in some detail by looking at LI BER’s EU project portfolio. Finally, change and growth can come through changes to legal frameworks, and the paper looks at the Hargreaves review of copyright frameworks in the UK and the launch of the new library-based EU lobbying group for copyright reform, Information Sans Frontières (IS F.

2008-06-01

Full Text Available Objective – This study examined low or non-use of the library at St. Martin’s College, UK and determined the possible reasons for this. Additionally, this study investigated the other sources of information non-users were accessing. The results were then fed into the library’s future strategic planning cycle. Methods – Using data from the TALIS management system, a postal survey was distributed to students who registered as low or non-users. Non-users were considered a hard-to-reach target group, and a further classroom-based survey was administered.Results – The findings showed that students in part-time and distance learning courses were the largest group of non-users. Other factors influencing non-use included the purchase of books, use of the Internet, and a lack of awareness of services available.Conclusions – The library service needs to target non-traditional student groups, particularly those taught off-campus, with innovative induction techniques. This survey highlighted the need to embed information skills teaching into the curriculum and a recent restructure of the department has enabled this to happen with a more focused approach to academic liaisonship.

Affinity-based screening of combinatorial libraries using automated, serial-column chromatography

Energy Technology Data Exchange (ETDEWEB)

Evans, D.M.; Williams, K.P.; McGuinness, B. [PerSeptive Biosystems, Framingham, MA (United States)] [and others

1996-04-01

The authors have developed an automated serial chromatographic technique for screening a library of compounds based upon their relative affinity for a target molecule. A {open_quotes}target{close_quotes} column containing the immobilized target molecule is set in tandem with a reversed-phase column. A combinatorial peptide library is injected onto the target column. The target-bound peptides are eluted from the first column and transferred automatically to the reversed-phase column. The target-specific peptide peaks from the reversed-phase column are identified and sequenced. Using a monoclonal antibody (3E-7) against {beta}-endorphin as a target, we selected a single peptide with sequence YGGFL from approximately 5800 peptides present in a combinatorial library. We demonstrated the applicability of the technology towards selection of peptides with predetermined affinity for bacterial lipopolysaccharide (LPS, endotoxin). We expect that this technology will have broad applications for high throughput screening of chemical libraries or natural product extracts. 21 refs., 4 figs.

Analyses of criticality and reactivity for TRACY experiments based on JENDL-3.3 data library

International Nuclear Information System (INIS)

Sono, Hiroki; Miyoshi, Yoshinori; Nakajima, Ken

2003-01-01

The parameters on criticality and reactivity employed for computational simulations of the TRACY supercritical experiments were analyzed using a recently revised nuclear data library, JENDL-3.3. The parameters based on the JENDL-3.3 library were compared to those based on two former-used libraries, JENDL-3.2 and ENDF/B-VI. In the analyses computational codes, MVP, MCNP version 4C and TWOTRAN, were used. The following conclusions were obtained from the analyses: (1) The computational biases of the effective neutron multiplication factor attributable to the nuclear data libraries and to the computational codes do not depend the TRACY experimental conditions such as fuel conditions. (2) The fractional discrepancies in the kinetic parameters and coefficients of reactivity are within ∼5% between the three libraries. By comparison between calculations and measurements of the parameters, the JENDL-3.3 library is expected to give closer values to the measurements than the JENDL-3.2 and ENDF/B-VI libraries. (3) While the reactivity worth of transient rods expressed in the $ unit shows ∼5% discrepancy between the three libraries according to their respective β eff values, there is little discrepancy in that expressed in the Δk/k unit.

Description of WIMS Library Update Project (WLUP)

International Nuclear Information System (INIS)

Leszczynski, Francisco

2002-01-01

WIMS-D is one of the few reactor lattice codes that are in the public domain and therefore are available on non-commercial terms, for research and power nuclear reactor calculations. The main weakness of the WIMS-D package is its multi-group constants library, which is based on very old data. Relatively good performance of WIMS-D is attributed to a series of empirical adjustments to the multi-group data. However, the adjustments are not always justified by more accurate and recent experimental measurements. In view of the recently available new, or revised, evaluated nuclear data files it was felt that the performance of WIMS-D could be improved by updating its library. The WIMS-D Library Update Project (WLUP) was initiated in the early 1990's and finished in 2001. The International Atomic Energy Agency (IAEA) supported its co-ordination, but the project itself consisted of voluntary contributions from a large number of participants. In due course, several benchmarks for testing the library were identified and analyzed, the WIMSR module of the NJOY code system was upgraded, a detailed parametric study was performed to investigate the effects of various data processing input options on integral results and, the data processing methods for the main reactor materials were optimized. The final product, available on CD-ROM from NDS-IAEA includes: 69 and 172 group WIMSD libraries prepared from the selected evaluated data files, IAEA-TECDOC with detailed documentation, Processing inputs, Benchmark inputs and, the system of auxiliary codes developed under the project.

Smith, J L; Connolly, B F; Davis, M; Graham, E; Wheeler, S

1984-01-01

The 1982 salary survey of the Medical Library Group of Southern California and Arizona (MLGSCA) indicates that 211 health sciences librarians in Southern California and Arizona earned a mean annual salary of $20,910 for 1982. Data analysis shows a positive correlation between salary and educational level. Other factors found to affect salary were job history, number of positions held, MLA certification, and professional responsibility. Age, gender, and MLA certification did not have a consistent positive correlation with salary. Results indicate that the salaries of hospital librarians are, on the average, roughly comparable to those of academic librarians in Southern California and Arizona. PMID:6743878

KAFAX-F22 : development and benchmark of multi-group library for fast reactor using JEF-2.2. Neutron 80 group and Photon 24 group

International Nuclear Information System (INIS)

Kim, Jung Do; Gil, Choong Sup.

1997-03-01

The KAFAX-F22 was developed from JEF-2.2, which is a MATXS format, multigroup library of fast reactor. The KAFAX-F22 has 80 and 24 energy group structures for neutron and photon, respectively. It includes 89 nuclide data processed by NJOY94.38. The TRANSX/TWODANT system was used for benchmark calculations of fast reactor and one- and two-dimensional calculations of ONEDANT and TWODANT were carried out with 80 group, P 3 S 16 and with 25 group, P 3 S 8 , respectively. The average values of multiplication factors are 0.99652 for MOX cores, 1.00538 for uranium cores and 1.00032 for total cores. Various central reaction rate ratios also give good agreements with the experimental values considering experimental uncertainties except for VERA-11A, VERA-1B, ZPR-6-7 and ZPR-6-6A cores of which experimental values seem to involve some problems.

1994-01-01

A new 69-group 96-material library has been created for use in WIMS-D4M. The latest SUN version of NJOY (91.27) was used to generate the ENDF/B-V-based cross-section library. The library also includes ENDF/B-V based fission yields, energy fission and energy per capture data. The upper energy boundary has been extended from 10 to 20 MeV in order to model high energy neutron reactions. Additional fuel and moderator temperatures have been included to better predict temperature coefficients. More excess potential scattering points have been added to increase the accuracy of self-shielded resonance cross-sections. Several benchmark comparisons have been made to validate the new library.

2013-09-01

Full Text Available ABSTRACTPurpose: The article uses sociological concepts in order to rethink the changes in library practices. Contemporary trends are discussed with regard to the changing nature of working habits, referring mostly to the new technology, and the (emergence of the third space phenomenon. The author does not regard libraries only as concrete public service institutions, but rather as complex cultural forms, taking in consideration wider social context with a stress on users’ practices in relation to space.Methodology/approach: The article is based on the (self- observation of the public library use, and on the (discourse analysis of internal library documents (i.e. annual reports and plans and secondary sociological literature. As such, the cultural form approach represents a classic method of sociology of culture.Results: The study of relevant material in combination with direct personal experiences reveals socio-structural causes for the change of users’ needs and habits, and points at the difficulty of spatial redefinition of libraries as well as at the power of the discourse.Research limitations: The article is limited to an observation of users’ practices in some of the public libraries in Ljubljana and examines only a small number of annual reports – the discoveries are then further debated from the sociological perspective.Originality/practical implications: The article offers sociological insight in the current issues of the library science and tries to suggest a wider explanation that could answer some of the challenges of the contemporary librarianship.

Development of the tool for generating ORIGEN2 library based on JENDL-3.2 for FBR

International Nuclear Information System (INIS)

Ohkawachi, Yasushi; Fukushima, Manabu

1999-05-01

ORIGEN2 is one of the most widely-used burnup analysis code in the world. This code has one-grouped cross section libraries compiled for various types of reactors. However, these libraries have some problems. One is that these libraries were developed from old nuclear data libraries (ENDF/B-IV,V) and the other is that core and fuel designs from which these libraries are generated do not match the current analysis. In order to solve the problems, analysis tool is developed for generating ORIGEN2 library from JENDL-3.2 considering multi-energy neutron spectrum. And eight new libraries are prepared using this tool for analysis of sodium-cooled FBR. These new libraries are prepared for eight kinds of cores in total. Seven of them are made by changing core size (small core - large core), fuel type (oxide, nitride, metal) and Pu vector as a parameter. The eighth one is a Pu burner core. Burnup calculation using both new and original libraries, shows large difference in buildup or depletion numbers of nuclides among the libraries. It is estimated that the analysis result is greatly influenced by the neutron spectrum which is used in collapse of cross section. By using this tool or new libraries, it seems to improve evaluation accuracy of buildup or depletion numbers of nuclides in transmutation research on FBR fuel cycle. (author)

Ritchie, A; Sowter, B

2000-01-01

This article reports on the results of an exploratory survey of the availability and accessibility of evidence-based information resources provided by medical libraries in Australia. Although barriers impede access to evidence-based information for hospital clinicians, the survey revealed that Medline and Cinahl are available in over 90% of facilities. In most cases they are widely accessible via internal networks and the Internet. The Cochrane Library is available in 69% of cases. The Internet is widely accessible and most libraries provide access to some full-text, electronic journals. Strategies for overcoming restrictions and integrating information resources with clinical workflow are being pursued. State, regional and national public and private consortia are developing agreements utilising on-line technology. These could produce cost savings and more equitable access to a greater range of evidence-based resources.

MOSFET-like CNFET based logic gate library for low-power application: a comparative study

International Nuclear Information System (INIS)

Gowri Sankar, P. A.; Udhayakumar, K.

2014-01-01

The next generation of logic gate devices are expected to depend upon radically new technologies mainly due to the increasing difficulties and limitations of existing CMOS technology. MOSFET like CNFETs should ideally be the best devices to work with for high-performance VLSI. This paper presents results of a comprehensive comparative study of MOSFET-like carbon nanotube field effect transistors (CNFETs) technology based logic gate library for high-speed, low-power operation than conventional bulk CMOS libraries. It focuses on comparing four promising logic families namely: complementary-CMOS (C-CMOS), transmission gate (TG), complementary pass logic (CPL) and Domino logic (DL) styles are presented. Based on these logic styles, the proposed library of static and dynamic NAND-NOR logic gates, XOR, multiplexer and full adder functions are implemented efficiently and carefully analyzed with a test bench to measure propagation delay and power dissipation as a function of supply voltage. This analysis provides the right choice of logic style for low-power, high-speed applications. Proposed logic gates libraries are simulated using Synopsys HSPICE based on the standard 32 nm CNFET model. The simulation results demonstrate that, it is best to use C-CMOS logic style gates that are implemented in CNFET technology which are superior in performance compared to other logic styles, because of their low average power-delay-product (PDP). The analysis also demonstrates how the optimum supply voltage varies with logic styles in ultra-low power systems. The robustness of the proposed logic gate library is also compared with conventional and state-art of CMOS logic gate libraries. (semiconductor integrated circuits)

The general-purpose Evaluated Nuclear Data File ENDF/B-VII.0 was released in December 2006. A number of sub-libraries were included in ENDF/B-VII.0 such that data were provided for incident neutrons, photons, and charged particles. This paper describes the creation of MCNP data libraries at Los Alamos National Laboratory based on three ENDF/B-VII.0 sub-libraries: neutrons, protons, and thermal scattering. An ACE-formatted continuous-energy neutron data library called ENDF70 for MCNP has been produced. This library provides data for 390 materials at five temperatures: 293.6, 600, 900, 1200, and 2500 K. The library was processed primarily with Version 248 of NJOY99. Extensive checking and quality-assurance tests were applied to the data. Improvements to the processing code were made and certain evaluations were modified as a result of these tests. ENDF/B-VII.0 included proton evaluations for 48 target materials. Forty-seven proton evaluations (all except for 13 C) were processed at room temperature and combined into the MCNP library ENDF70PROT. Neutron thermal S(α,β) scattering data exist for twenty different materials in ENDF/B-VII.0. All twenty of these evaluations were processed at all applicable temperatures (these vary for each evaluation), and combined into the MCNP library ENDF70SAB. All of these ENDF/B-VII.0 based MCNP libraries (ENDF70, ENDF70PROT, and ENDF70SAB) are available as part of the MCNP5 1.50 release. (authors)

2000-07-01

Full Text Available Abstract In order to simultaneously integrate linkage and syntenic groups to the ovine chromosomal map, a sheep bacterial artificial chromosome (BAC library was screened with previously assigned microsatellites using a sheep-hamster hybrid panel and genetic linkage. Thirty-three BACs were obtained, fluorescently labelled and hybridised on sheep-goat hybrid metaphases (2n = 57. This study allowed us, (i, to anchor all linkage groups on sheep chromosomes, (ii, to give information on the probable position of the centromere on the linkage map for the centromeric chromosomes, (iii, to contradict the previous orientation of the ovine × linkage group by the mapping of BMS1008 on OARXq38. Concerning our somatic cell hybrid panel, this study resulted in the assignment of all the previously unassigned groups to ovine chromosomes and a complete characterisation of the hybrid panel. In addition, since hybridisations were performed on a sheep-goat hybrid, new marker/anchoring points were added to the caprine cytogenetic map.

2014-10-01

Full Text Available As the move to cloud-based SaaS library systems accelerates, we must consider what it means to develop applications when the core of the system isn't under the library's control. The entire application lifecycle is changing, from development to testing to production. Developing applications for cloud solutions raises new concerns, such as security, multi-tenancy, latency, and analytics. In this article, we review the landscape and suggest a view of how to be successful for the benefit of library staff and end-users in this new reality. We discuss what kinds of APIs and protocols vendors should be supporting, and suggest how best to take advantage of the innovations being introduced.

Production of neutronic discrete equations for a cylindrical geometry in one group energy and benchmark the results with MCNP-4B code with one group energy library

International Nuclear Information System (INIS)

Salehi, A. A.; Vosoughi, N.; Shahriari, M.

2002-01-01

In reactor core neutronic calculations, we usually choose a control volume and investigate about the input, output, production and absorption inside it. Finally, we derive neutron transport equation. This equation is not easy to solve for simple and symmetrical geometry. The objective of this paper is to introduce a new direct method for neutronic calculations. This method is based on physics of problem and with meshing of the desired geometry, writing the balance equation for each mesh intervals and with notice to the conjunction between these mesh intervals, produce the final discrete equation series without production of neutron transport differential equation and mandatory passing form differential equation bridge. This method, which is named Direct Discrete Method, was applied in static state, for a cylindrical geometry in one group energy. The validity of the results from this new method are tested with MCNP-4B code with a one group energy library. One energy group direct discrete equation produces excellent results, which can be compared with the results of MCNP-4B

Neutron cross section libraries for analysis of fusion neutronics experiments

International Nuclear Information System (INIS)

Kosako, Kazuaki; Oyama, Yukio; Maekawa, Hiroshi; Nakamura, Tomoo

1988-03-01

We have prepared two computer code systems producing neutron cross section libraries to analyse fusion neutronics experiments. First system produces the neutron cross section library in ANISN format, i.e., the multi-group constants in group independent format. This library can be obtained by using the multi-group constant processing code system MACS-N and the ANISN format cross section compiling code CROKAS. Second system is for the continuous energy cross section library for the MCNP code. This library can be obtained by the nuclear data processing system NJOY which generates pointwise energy cross sections and the cross section compiling code MACROS for the MCNP library. In this report, we describe the production procedures for both types of the cross section libraries, and show six libraries with different conditions in ANISN format and a library for the MCNP code.

WIMS-D library update

International Nuclear Information System (INIS)

2007-05-01

WIMS-D (Winfrith Improved Multigroup Scheme-D) is the name of a family of software packages for reactor lattice calculations and is one of the few reactor lattice codes in the public domain and available on noncommercial terms. WIMSD-5B has recently been released from the OECD Nuclear Energy Agency Data Bank, and features major improvements in machine portability, as well as incorporating a few minor corrections. This version supersedes WIMS-D/4, which was released by the Winfrith Technology Centre in the United Kingdom for IBM machines and has been adapted for various other computer platforms in different laboratories. The main weakness of the WIMS-D package is the multigroup constants library, which is based on very old data. The relatively good performance of WIMS-D is attributed to a series of empirical adjustments to the multigroup data. However, the adjustments are not always justified on the basis of more accurate and recent experimental measurements. Following the release of new and revised evaluated nuclear data files, it was felt that the performance of WIMS-D could be improved by updating the associated library. The WIMS-D Library Update Project (WLUP) was initiated in the early 1990s with the support of the IAEA. This project consisted of voluntary contributions from a large number of participants. Several benchmarks for testing the library were identified and analysed, the WIMSR module of the NJOY code system was upgraded and the author of NJOY accepted the proposed updates for the official code system distribution. A detailed parametric study was performed to investigate the effects of various data processing input options on the integral results. In addition, the data processing methods for the main reactor materials were optimized. Several partially updated libraries were produced for testing purposes. The final stage of the WLUP was organized as a coordinated research project (CRP) in order to speed up completion of the fully updated library

Chamberlain, David; Brook, Richard

2014-03-01

Health organisations are often driven by specific targets defined by mission statements, aims and objectives to improve patient care. Health libraries need to demonstrate that they contribute to organisational objectives, but it is not clear how nurses view that contribution. To investigate ward nursing staff motivations, their awareness of ward and organisational objectives; and their attitudes towards the contribution of health library services to improving patient care. Qualitative research using focus group data was combined with content analysis of literature evidence and library statistics (quantitative data). Data were analysed using thematic coding, divided into five group themes: understanding of Trust, Ward and Personal objectives, use of Library, use of other information sources, quality and Issues. Four basic social-psychological processes were then developed. Behaviour indicates low awareness of organisational objectives despite patient-centric motivation. High awareness of library services is shown with some connection made by ward staff between improved knowledge and improved patient care. There was a two-tiered understanding of ward objectives and library services, based on level of seniority. However, evidence-based culture needs to be intrinsic in the organisation before all staff benefit. Libraries can actively engage in this at ward and board level and improve patient care by supporting organisational objectives. © 2014 The author.

Full Text Available This study analyzes how users perform information retrieval tasks when introducing queries to the Hispanic Digital Library. Clusters of users are differentiated based on their distinct information behavior. The study used the log files collected by the server over a year and different possible clustering algorithms are compared. The k-means algorithm is found to be a suitable clustering method for the analysis of large log files from digital libraries. In the case of the Hispanic Digital Library the results show three clusters of users and the characteristic information behavior of each group is described.

Library based x-ray scatter correction for dedicated cone beam breast CT

International Nuclear Information System (INIS)

Purpose: The image quality of dedicated cone beam breast CT (CBBCT) is limited by substantial scatter contamination, resulting in cupping artifacts and contrast-loss in reconstructed images. Such effects obscure the visibility of soft-tissue lesions and calcifications, which hinders breast cancer detection and diagnosis. In this work, we propose a library-based software approach to suppress scatter on CBBCT images with high efficiency, accuracy, and reliability. Methods: The authors precompute a scatter library on simplified breast models with different sizes using the GEANT4-based Monte Carlo (MC) toolkit. The breast is approximated as a semiellipsoid with homogeneous glandular/adipose tissue mixture. For scatter correction on real clinical data, the authors estimate the breast size from a first-pass breast CT reconstruction and then select the corresponding scatter distribution from the library. The selected scatter distribution from simplified breast models is spatially translated to match the projection data from the clinical scan and is subtracted from the measured projection for effective scatter correction. The method performance was evaluated using 15 sets of patient data, with a wide range of breast sizes representing about 95% of general population. Spatial nonuniformity (SNU) and contrast to signal deviation ratio (CDR) were used as metrics for evaluation. Results: Since the time-consuming MC simulation for library generation is precomputed, the authors’ method efficiently corrects for scatter with minimal processing time. Furthermore, the authors find that a scatter library on a simple breast model with only one input parameter, i.e., the breast diameter, sufficiently guarantees improvements in SNU and CDR. For the 15 clinical datasets, the authors’ method reduces the average SNU from 7.14% to 2.47% in coronal views and from 10.14% to 3.02% in sagittal views. On average, the CDR is improved by a factor of 1.49 in coronal views and 2.12 in sagittal

Modeling of frequency agile devices: development of PKI neuromodeling library based on hierarchical network structure

Science.gov (United States)

Sanchez, P.; Hinojosa, J.; Ruiz, R.

2005-06-01

Recently, neuromodeling methods of microwave devices have been developed. These methods are suitable for the model generation of novel devices. They allow fast and accurate simulations and optimizations. However, the development of libraries makes these methods to be a formidable task, since they require massive input-output data provided by an electromagnetic simulator or measurements and repeated artificial neural network (ANN) training. This paper presents a strategy reducing the cost of library development with the advantages of the neuromodeling methods: high accuracy, large range of geometrical and material parameters and reduced CPU time. The library models are developed from a set of base prior knowledge input (PKI) models, which take into account the characteristics common to all the models in the library, and high-level ANNs which give the library model outputs from base PKI models. This technique is illustrated for a microwave multiconductor tunable phase shifter using anisotropic substrates. Closed-form relationships have been developed and are presented in this paper. The results show good agreement with the expected ones.

Establishing a PWR burn-up library

International Nuclear Information System (INIS)

Lutz, D.C.

1981-01-01

Starting out from data file ENDF/B IV /1/, a cross-section library has been established for the calculation of operating conditions in pressurized water reactors of the type used in BIBLIS B. The library includes macroscopic, homogenized 2-group cross-sections for all types of fuel elements used in this reactor, including those equipped with boron glass rods. For their calculation the previous irradiation of the fuel has been taken into consideration by approximation. Information on fuel consumption from cell burn-up calculations has been stored in a separate data file. It was designed as a base for the determination of cross sections to be used in the calculation of the incident ''main-steam pipe fracture''. For this library the description of cross sections as a function of the moderator status chose the water densities at 300 0 C/155 bar, 190 0 C/140 bar and 100 0 C/100 bar as fixed values. The burn-up library has been tested by a three-dimensional calculation for the 1sup(st) cycle of the BIBLIS B-reactor using program QUABOX /2/. This showed variances with the anticipated course concerning critically, which can be explained almost quantitatively by known deficiencies of the ENDF/b-IV library. (orig.) [de

Full Text Available Objective – To discover the attitudes of twelve to fifteen year-olds toward the public library.Design – Mixed methodology consisting of a survey and focus groups.Setting – An Eastern Canadian regional municipality.Subjects – Twelve to fifteen year-old middle school students.Methods – Using a disproportionate stratified sample and multistage clustering, the author mailed 900 surveys to middle school students; 249 surveys were completed and usable. Those students who completed the survey and who also indicated they would be willing to participate in a focus group were randomly selected to participate in nine focus groups with between 7 to 12 students in each group.Main Results – Discrepancies exist between the teens’ level of satisfaction with the library indicated on the survey (high and expressed in the focus groups (low. Teens seldom use the public library due to: their non-existent relationship with library staff, although teens who were “active readers” used the library more; lack of appealing programs and program promotion; no teen-focused website; poor teen facilities within the library; and an overall failure of the public libraries to include teenagers.Conclusion – Public libraries need to be more responsive to teen needs to attract teens to use the library. To uncover these needs, libraries should use mixed methods of discovery.

JSD1000: multi-group cross section sets for shielding materials

International Nuclear Information System (INIS)

Yamano, Naoki

1984-03-01

A multi-group cross section library for shielding safety analysis has been produced by using ENDF/B-IV. The library consists of ultra-fine group cross sections, fine-group cross sections, secondary gamma-ray production cross sections and effective macroscopic cross sections for typical shielding materials. Temperature dependent data at 300, 560 and 900 K have been also provided. Angular distributions of the group to group transfer cross section are defined by a new method of ''Direct Angular Representation'' (DAR) instead of the method of finite Legendre expansion. The library designated JSD1000 are stored in a direct access data base named DATA-POOL and data manipulations are available by using the DATA-POOL access package. The 3824 neutron group data of the ultra-fine group cross sections and the 100 neutron, 20 photon group cross sections are applicable to shielding safety analyses of nuclear facilities. This report provides detailed specifications and the access method for the JSD1000 library. (author)

Punjab Institute of Cardiology (PIC) is a recognised teaching hospital for cardiac care in the Punjab province of Pakistan. PIC has established a library to fulfil the research and information needs of health care professionals. This study aims to evaluate the satisfaction of users with the services of PIC library. A purposive sample of 15 health care professionals was selected. A semistructured interview technique based on an interview guide was used for collection of data. The data were qualitatively analysed using a thematic approach. Users of PIC library were satisfied with the library collection, organisation, reference and circulation services, staff attitudes, cooling and heating. They were concerned about library space, hours, furniture and environment, and suggested more availability of electronic library services, newer collections, better Internet access and comfortable furniture. The study proved useful to investigate users' satisfaction with the services of PIC library. It concludes that the PIC library should maintain and strengthen the services with which users are satisfied, and improve those about which they are concerned. The study will be useful to libraries in other developing countries for improvement in their services. © 2013 The authors. Health Information and Libraries Journal © 2013 Health Libraries Group.

Yeivin, Y.; Marable, J.H.; Weisbin, C.R.; Wagschal, J.J.

1980-01-01

Benchmark integral-experiment values from six fast critical-reactor assemblies and two standard neutron fields are combined with corresponding calculations using group cross sections based on ENDF/B-V in a least-squares data adjustment using evaluated covariances from ENDF/B-V and supporting covariance evaluations. Purpose is to produce an adjusted cross-section and covariance library which is based on well-documented data and methods and which is suitable for fast-reactor design. By use of such a library, data- and methods-related biases of calculated performance parameters should be reduced and uncertainties of the calculated values minimized. Consistency of the extensive data base is analyzed using the chi-square test. This adjusted library ORACLE will be available shortly

In the past 20 years, synthetic combinatorial methods have fundamentally advanced the ability to synthesize and screen large numbers of compounds for drug discovery and basic research. Mixture-based libraries and positional scanning deconvolution combine two approaches for the rapid identification of specific scaffolds and active ligands. Here we present a quantitative assessment of the screening of 32 positional scanning libraries in the identification of highly specific and selective ligands for two formylpeptide receptors. We also compare and contrast two mixture-based library approaches using a mathematical model to facilitate the selection of active scaffolds and libraries to be pursued for further evaluation. The flexibility demonstrated in the differently formatted mixture-based libraries allows for their screening in a wide range of assays.

Oberacher, Herbert; Weinmann, Wolfgang; Dresen, Sebastian

2011-06-01

Tandem mass spectral libraries are gaining more and more importance for the identification of unknowns in different fields of research, including metabolomics, forensics, toxicology, and environmental analysis. Particularly, the recent invention of reliable, robust, and transferable libraries has increased the general acceptance of these tools. Herein, we report on results obtained from thorough evaluation of the match reliabilities of two tandem mass spectral libraries: the MSforID library established by the Oberacher group in Innsbruck and the Weinmann library established by the Weinmann group in Freiburg. Three different experiments were performed: (1) Spectra of the libraries were searched against their corresponding library after excluding either this single compound-specific spectrum or all compound-specific spectra prior to searching; (2) the libraries were searched against each other using either library as reference set or sample set; (3) spectra acquired on different mass spectrometric instruments were matched to both libraries. Almost 13,000 tandem mass spectra were included in this study. The MSforID search algorithm was used for spectral matching. Statistical evaluation of the library search results revealed that principally both libraries enable the sensitive and specific identification of compounds. Due to higher mass accuracy of the QqTOF compared with the QTrap instrument, matches to the MSforID library were more reliable when comparing spectra with both libraries. Furthermore, only the MSforID library was shown to be efficiently transferable to different kinds of tandem mass spectrometers, including "tandem-in-time" instruments; this is due to the coverage of a large range of different collision energy settings-including the very low range-which is an outstanding characteristics of the MSforID library.

Generation of the WIMS code library from the ENDF/B-VI basic library

Aboustta, Mohamed Ali Bashir.

1994-01-01

The WIMS code is being presently used in many research centers and educational institutions in the world. It has proven to be versatile, reliable and diverse as it is used to calculate different reactor systems. Its data library is rich of useful information that can even be condensed to serve other codes, but the copy distributed with the code is not updated. Some of its data has never been changed, others had changed many times to accommodate certain experimental setups and some data is, simply, not included. This work is an attempt to dominate the techniques used in generating a multigroup library as being applied to the WIMS data library. This new library is called UFMGLIB. A new set of consistent data was generated from the basic ENDF/B-VI library, including complete data for the fission product nuclides and more elaborated burnup chains. The performance of the library is comparable to that of the Standard library accompanying the code and a later library, WIMKAL 88, generated by a group of the Korean Research Institute of Atomic Energy.

gLibrary/DRI: A grid-based platform to host multiple repositories for digital content

Calanducci, A.; Gonzalez Martin, J. M.; Ramos Pollan, R.; Rubio del Solar, M.; Tcaci, S.

2007-01-01

In this work we present the gLibrary/DRI (Digital Repositories Infrastructure) platform. gLibrary/DRI extends gLibrary, a system with a easy-to-use web front-end designed to save and organize multimedia assets on Grid-based storage resources. The main goal of the extended platform is to reduce the cost in terms of time and effort that a repository provider spends to get its repository deployed. This is achieved by providing a common infrastructure and a set of mechanisms (APIs and specifications) that the repository providers use to define the data model, the access to the content (by navigation trees and filters) and the storage model. DRI offers a generic way to provide all this functionality; nevertheless the providers can add specific behaviours to the default functions for their repositories. The architecture is Grid based (VO system, data federation and distribution, computing power, etc). A working example based on a mammograms repository is also presented. (Author)

Camelids have unique antibodies, namely HCAbs (VHH) or commercially named Nanobodies(®) (Nb) that are composed only of a heavy-chain homodimer. As libraries based on immunized camelids are time-consuming, costly and likely redundant for certain antigens, we describe the construction of a naïve camelid VHHs library from blood serum of non-immunized camelids with affinity in the subnanomolar range and suitable for standard immune applications. This approach is rapid and recovers VHH repertoire with the advantages of being more diverse, non-specific and devoid of subpopulations of specific antibodies, which allows the identification of binders for any potential antigen (or pathogen). RNAs from a number of camelids from Saudi Arabia were isolated and cDNAs of the diverse vhh gene were amplified; the resulting amplicons were cloned in the phage display pSEX81 vector. The size of the library was found to be within the required range (10(7)) suitable for subsequent applications in disease diagnosis and treatment. Two hundred clones were randomly selected and the inserted gene library was either estimated for redundancy or sequenced and aligned to the reference camelid vhh gene (acc. No. ADE99145). Results indicated complete non-specificity of this small library in which no single event of redundancy was detected. These results indicate the efficacy of following this approach in order to yield a large and diverse enough gene library to secure the presence of the required version encoding the required antibodies for any target antigen. This work is a first step towards the construction of phage display-based biosensors useful in disease (e.g., TB or tuberculosis) diagnosis and treatment. Copyright © 2014 Académie des sciences.

In the paper API-library software developed by students of Applied and Computer Optics Department (ITMO University) for optical system design is presented. The library performs paraxial and real ray tracing, calculates 3d order (Seidel) aberration and real ray aberration of axis and non-axis beams (wave, lateral, longitudinal, coma, distortion etc.) and finally, approximate wave aberration by Zernike polynomials. Real aperture can be calculated by considering of real rays tracing failure on each surface. So far we assume optical system is centered, with spherical or 2d order aspherical surfaces. Optical glasses can be set directly by refraction index or by dispersion coefficients. The library can be used for education or research purposes in optical system design area. It provides ready to use software functions for optical system simulation and analysis that developer can simply plug into their software development for different purposes, for example for some specific synthesis tasks or investigation of new optimization modes. In the paper we present an example of using the library for development of cemented doublet synthesis software based on Slusarev's methodology. The library is used in optical system optimization recipes course for deep studying of optimization model and its application for optical system design. Development of such software is an excellent experience for students and help to understanding optical image modeling and quality analysis. This development is organized as student group joint project. We try to organize it as a group in real research and development project, so each student has his own role in the project and then use whole library functionality in his own master or bachelor thesis. Working in such group gives students useful experience and opportunity to work as research and development engineer of scientific software in the future.

Library Services Funding Assessment

Lorig, Jonathan A.

2004-01-01

The Glenn Technical Library is a science and engineering library that primarily supports research activities at the Glenn Research Center, and provides selected services to researchers at all of the NASA research centers. Resources available in the library include books, journals, CD-ROMs, and access to various online sources, as well as live reference and inter-library loan services. The collection contains over 77,000 books, 800,000 research reports, and print or online access to over 1,400 journals. Currently the library operates within the Logistics and Technical Information Division, and is funded as an open-access resource within the GRC. Some of the research units at the GRC have recently requested that the library convert to a "pay-for-services" model, in which individual research units could fund only those journal subscriptions for which they have a specific need. Under this model, the library would always maintain a certain minimum level of pooled-expense services, including the ready reference and book collections, and inter-library loan services. Theoretically the "pay-for-services" model would encourage efficient financial allocation, and minimize the extent to which paid journal subscriptions go unused. However, this model also could potentially negate the benefits of group purchases for journal subscriptions and access. All of the major journal publishers offer package subscriptions that compare favorably in cost with the sum of individual subscription costs for a similar selection of titles. Furthermore, some of these subscription packages are "consortium" purchases that are funded collectively by the libraries at multiple NASA research centers; such consortia1 memberships would be difficult for the library to pay, if enough GRC research units were to withdraw their pooled contributions. cost of collectively-funded journal access with the cost of individual subscriptions. My primary task this summer is to create the cost dataset framework, and

2018-02-12

An efficient solid-phase synthetic route for the construction of 1,3,4-oxadiazole and 1,3,4-thiadiazole libraries based on branching diversity-oriented synthesis (DOS) has been developed in this study. The core skeleton resins, 1,3,4-oxadiazole and 1,3,4-thiadiazole, were obtained through desulfurative and dehydrative cyclizations of thiosemicarbazide resin, respectively. Various functional groups have been introduced to the core skeleton resins, such as aryl, amine, amide, urea, thiourea, and an amino acid. Most of the libraries were purified by simple trituration without extraction or column chromatography after cleavage of the products from the solid-supported resin. As a result, we obtained high yields of pure 1,3,4-oxadiazole and 1,3,4-thiadiazole derivatives (total numbers = 128). Finally, we confirmed the drug-like properties of our library by calculation of physicochemical properties, displays of the skeletal diversities of the library in 3D-space, and occupation of a broad range of areas by their functional groups.

Energy group structure determination using particle swarm optimization

Yi, Ce; Sjoden, Glenn

2013-01-01

Highlights: ► Particle swarm optimization is applied to determine broad group structure. ► A graph representation of the broad group structure problem is introduced. ► The approach is tested on a fuel-pin model. - Abstract: Multi-group theory is widely applied for the energy domain discretization when solving the Linear Boltzmann Equation. To reduce the computational cost, fine group cross libraries are often down-sampled into broad group cross section libraries. Cross section data collapsing generally involves two steps: Firstly, the broad group structure has to be determined; secondly, a weighting scheme is used to evaluate the broad cross section library based on the fine group cross section data and the broad group structure. A common scheme is to average the fine group cross section weighted by the fine group flux. Cross section collapsing techniques have been intensively researched. However, most studies use a pre-determined group structure, open based on experience, to divide the neutron energy spectrum into thermal, epi-thermal, fast, etc. energy range. In this paper, a swarm intelligence algorithm, particle swarm optimization (PSO), is applied to optimize the broad group structure. A graph representation of the broad group structure determination problem is introduced. And the swarm intelligence algorithm is used to solve the graph model. The effectiveness of the approach is demonstrated using a fuel-pin model

2004-01-01

Objective: The objective is to provide information on basic issues in library management identified by the Medical Library Association's (MLA's) seventh triennial salary survey. Methods: The survey was a Web-based questionnaire. A nonrandom sample of persons was obtained by posting messages to MLA's membership and to the MEDLIB-L email discussion list. Employed MLA members and nonmembers employed in medical library settings filled out a Web-based form designed using common gateway interface (CGI) programming. Results: Six hundred forty-five usable responses were analyzed by the Hay Group and presented in the MLA publication, Hay Group/MLA 2001 Compensation and Benefits Survey. Results from the 2001 survey in this article focus on pay and job satisfaction. Salary survey results since 1983 were analyzed to review trends in seniority, diversity, and pay equity. Conclusions: Given the age progression of respondents from 1983 to 2001, it is clear that succession planning is a core issue for medical libraries. Although efforts to create more diversity in medical libraries in member organizations have started to yield results, pay for white respondents has increased at a higher rate than for other racial categories. The authors found that the pay-for-performance system in the organizations of approximately two-thirds of the respondents is suboptimized and that most of the reasons medical librarians cite for leaving their organization can be addressed and potentially changed by management. Results from the eighth salary survey, slated to be conducted in the fall of 2004, will further track these trends and issues. PMID:15494762

Full Text Available In recent years, there has been a demand to include doctoral students and researchers in the curriculum for information literacy. Not only information search, but also the expertise of the librarians in scientific publishing, bibliometric analysis is demanded. As a result of the demand the two universities in Turku/Åbo have developed their research services. The libraries have also met for benchmarking and further cooperation is being discussed. 1.The implementation of three focus group interviews with 18 researchers at Åbo Akademi University The Focus Group survey methodology has its roots in social science qualitative research. It is widely used in the library world and is considered to be suitable particularly well for the evaluation and development of library services. The overall purpose with our interviews was to obtain feedback on how library users (in this case, researchers and graduate students wish ÅAUL to develop its services to better meet their needs. Three group interviews were conducted, with 6-8 participators. The following questions were, among others, discussed in every session: How do the researchers perceive the library's role in their daily work? What is the starting point for retrieving information (e.g. The MetaLib portal, Google Scholar or other? Is there a need for courses/more supervision in information search and reference management? Is there a need for tailored and integrated library services? As a result of the sessions and analysis of the group discussions a number of measures were proposed: Targeted teaching of subject-specific databases, more topic-specific sessions in the library portal and RefWorks. Compulsory information retrieval course for first year doctoral students. Information Weeks or "hands on" sessions on campus libraries. The library should participate more in workshops and seminars to increase their visibility and their services. The library should actively consider how to measure the impact and

Vinogradov, Alexander A; Gates, Zachary P; Zhang, Chi; Quartararo, Anthony J; Halloran, Kathryn H; Pentelute, Bradley L

2017-11-13

A methodology to achieve high-throughput de novo sequencing of synthetic peptide mixtures is reported. The approach leverages shotgun nanoliquid chromatography coupled with tandem mass spectrometry-based de novo sequencing of library mixtures (up to 2000 peptides) as well as automated data analysis protocols to filter away incorrect assignments, noise, and synthetic side-products. For increasing the confidence in the sequencing results, mass spectrometry-friendly library designs were developed that enabled unambiguous decoding of up to 600 peptide sequences per hour while maintaining greater than 85% sequence identification rates in most cases. The reliability of the reported decoding strategy was additionally confirmed by matching fragmentation spectra for select authentic peptides identified from library sequencing samples. The methods reported here are directly applicable to screening techniques that yield mixtures of active compounds, including particle sorting of one-bead one-compound libraries and affinity enrichment of synthetic library mixtures performed in solution.

Using scientific evidence to improve hospital library services: Southern Chapter/Medical Library Association journal usage study.

Dee, C R; Rankin, J A; Burns, C A

1998-07-01

Journal usage studies, which are useful for budget management and for evaluating collection performance relative to library use, have generally described a single library or subject discipline. The Southern Chapter/Medical Library Association (SC/MLA) study has examined journal usage at the aggregate data level with the long-term goal of developing hospital library benchmarks for journal use. Thirty-six SC/MLA hospital libraries, categorized for the study by size as small, medium, or large, reported current journal title use centrally for a one-year period following standardized data collection procedures. Institutional and aggregate data were analyzed for the average annual frequency of use, average costs per use and non-use, and average percent of non-used titles. Permutation F-type tests were used to measure difference among the three hospital groups. Averages were reported for each data set analysis. Statistical tests indicated no significant differences between the hospital groups, suggesting that benchmarks can be derived applying to all types of hospital libraries. The unanticipated lack of commonality among heavily used titles pointed to a need for uniquely tailored collections. Although the small sample size precluded definitive results, the study's findings constituted a baseline of data that can be compared against future studies.

Full Text Available Background and Objectives: Evidence based librarianship (EBL was defined as “use of best available evidence from qualitative and quantitative research results and rational experience and decisions acquired from the daily practice of library”. However there are controversies about if the nature of EBL deals with library services or professional practice and if it needs a formal education or informal continuing education is enough? To shed light on this ambiguity, the aim of this study was to find out the state-of-the-art of education of EBL in the world. Material and Methods: The study utilized library and documentation methods to investigate the academic education of EBL through review of the available literature and websites. Results: The findings of the study revealed that evidence based librarianship does have formal curriculum for academic education in post graduate levels (post master and master. It also revealed that “Evidence Based Approach” (EBA and “Evidence Based Medicine” (EBM were also similar courses that are offered in Master and PhD levels. Conclusion: Based on the history and revolution of EBA, it is time to develop formal curriculum and field of study for Evidence Based Information Practice. This study suggests establishment of the academic field of Evidence Based and Information Science to overcome the problems and limitations that library science faces in practice.

Full Text Available This study aimed at establishing service quality determinants which may affect customer satisfaction in university libraries in Sri Lanka. Using the literature, 113 service quality determinants were identified. These were then reviewed by eight focus groups in four different universities. Forty of the determinants were perceived to be applicable to their context. The participants also added 14 quality requirements which they thought were not provided for in the list. Finally, the content and face validity of the 54 determinants were evaluated by a panel of experts who ultimately reduced them to 50. This study recommends the use of the identified quality determinants by library administrators and policymakers in the higher education sector in Sri Lanka to gauge the levels of customer satisfaction and assure quality of service.

Organizational prerequisites for the preservation of library collections in monastery libraries

libraries. The conceptual approach to heritage preservation in monastery libraries used in this paper is based on the theoretical model of written heritage preservation management that comprises five aspects bringing together the theoretical, strategic, legal, financial, educational, operative, and cultural components. Monastery libraries are facing many problems in protection and preservation of collections. Most of their problems fall under the economic, legal, material and operative aspects of preservation. In addition to the most common limitations, such as financial constraints, inadequate premises for keeping and storing the collections, they often have staff shortages, especially of trained staff with particular knowledge and skills required to protect the collections of such libraries, which brings the educational aspect of preservation into the foreground. Even though the protection and preservation of library collections in monastery libraries is mostly the responsibility of monastery monks, their knowledge is mostly not expert enough and they cannot be the only ones made responsible for preservation. This issue needs to be considered from the strategic and theoretical aspects of written heritage preservation management. One of the major hurdles is the inadequacy of legislation and its lack of recognition of those collections as national heritage. One of the factors that needs to be taken into consideration are changes that occur in the cultural and social contexts, i.e. changes in relations between church orders and communities in which they are active. Based on the data collected and relying on the conceptual model of written heritage preservation management in the Republic of Croatia, the current state of monastery library collections preservation has been established and measures for a systematic and more efficient management of written heritage preservation in monastery libraries have been proposed.

The bacterial CRISPR system is fast becoming the most popular genetic and epigenetic engineering tool due to its universal applicability and adaptability. The desire to deploy CRISPR-based methods in a large variety of species and contexts has created an urgent need for the development of easy, time- and cost-effective methods enabling large-scale screening approaches. Here we describe CORALINA (comprehensive gRNA library generation through controlled nuclease activity), a method for the generation of comprehensive gRNA libraries for CRISPR-based screens. CORALINA gRNA libraries can be derived from any source of DNA without the need of complex oligonucleotide synthesis. We show the utility of CORALINA for human and mouse genomic DNA, its reproducibility in covering the most relevant genomic features including regulatory, coding and non-coding sequences and confirm the functionality of CORALINA generated gRNAs. The simplicity and cost-effectiveness make CORALINA suitable for any experimental system. The unprecedented sequence complexities obtainable with CORALINA libraries are a necessary pre-requisite for less biased large scale genomic and epigenomic screens.

2018-03-02

The recent establishment of cloud computing, high-throughput networking, and more versatile web standards and browsers has led to a renewed interest in web-based applications. While traditionally big data has been the domain of optimized desktop and server applications, it is now possible to store vast amounts of data and perform the necessary calculations offsite in cloud storage and computing providers, with the results visualized in a high-quality cross-platform interface via a web browser. There are number of emerging platforms for cloud-based mass spectrometry data analysis; however, there is limited pre-existing code accessible to web developers, especially for those that are constrained to a shared hosting environment where Java and C applications are often forbidden from use by the hosting provider. To remedy this, we provide an open-source mass spectrometry library for one of the most commonly used web development languages, PHP. Our new library, phpMs, provides objects for storing and manipulating spectra and identification data as well as utilities for file reading, file writing, calculations, peptide fragmentation, and protein digestion as well as a software interface for controlling search engines. We provide a working demonstration of some of the capabilities at http://pgb.liv.ac.uk/phpMs .

Full Text Available Objective – To evaluate the effectiveness of the San Jose State University Library internship program.Design – Focus group; single point in time; qualitative design.Setting – Large academic library in the United States of America.Subjects – Nine former interns of the San Jose State University (SJSU Library.Methods - Nine former interns of the SJSU Library internship program participated in a single 90-minute session. No inducements for participation were offered. A moderator asked a series of 10 questions designed to gather feedback in three areas: 1 “the internship as part of the Masters program,” 2 “the internship’s role in the realization of personal objectives and professional development,” and 3 “the experience of working in team based activities.” A digital voice recorder captured the participants’ responses, allowing for detailed analysis of the responses after the session.Main Results – The interns deemed their overall experience successful, as all indicated they achieved their professional development objectives for the internship. However, the interns also indicated their experience could have been improved by the appointment of a single dedicated coordinator for recruitment and oversight, as well as more feedback on the quality of their work, especially for course-related instruction.Conclusion – The SJSU Library determined that the internship program was advantageous to both the Library and the interns. All of the interns who participated in the focus group achieved their profession development objectives for the internship. Additionally, the Library received valuable feedback for improving the program. Suggestions included appointing a dedicated internship coordinator, allowing interns more of an opportunity to choose their projects, and ensuring that interns are offered frequent feedback about the quality of their work.

Leisure reading collections in academic health sciences and science libraries: results of visits to seven libraries.

Watson, Erin M

2014-03-01

To visit leisure reading collections in academic science and health sciences libraries to determine how they function and what role they play in their libraries. The author visited seven libraries with leisure reading collections and carried out a semistructured interview with those responsible either for selection of materials or for the establishment of the collection. These collections contained a variety of materials, with some libraries focusing on health-science-related materials and others on providing recreational reading. The size of the collections also varied, from 186 to 9700 books, with corresponding differences in budget size. All collections were housed apart, with the same loan period as the regular collection. No collections contained electronic materials. Although there was little comparable statistical data on usage, at the six libraries at which active selection was occurring, librarians and library staff felt that the collection was well used and felt that it provided library users with benefits such as stress relief and relaxation and exposure to other perspectives. Librarians and library staff at the libraries that undertook active selection felt that their leisure reading collection was worthwhile. It would be interesting for future work to focus on the user experience of such collections. © 2013 The author. Health Information and Libraries Journal © 2013 Health Libraries Group.

2014-01-01

With textbook readers and digital downloads proliferating, it is easy to imagine a time when printed books will vanish. Such forecasts miss the mark, argue Jeffrey Schnapp and Matthew Battles. Future bookshelves will not be wholly virtual, and libraries will thrive although in a variety of new social, cultural, and architectural forms. Schnapp and Battles combine deep study of the library s history with a record of institutional and technical innovation at metaLAB, a research group at the forefront of the digital humanities. They gather these currents in The Library Beyond the Book," exploring what libraries have been in the past to speculate on what they will become: hybrid places that intermingle books and ebooks, analog and digital formats, paper and pixels. Libraries have always been mix-and-match spaces, and remix is their most plausible future scenario.

Finding novel chemical agents for targeting disease associated drug targets often requires screening of large number of new chemical libraries. In silico methods are generally implemented at initial stages for virtual screening. Filtering of such compound libraries on physicochemical and substructure ground is done to ensure elimination of compounds with undesired chemical properties. Filtering procedure, is redundant, time consuming and requires efficient bioinformatics/computer manpower along with high end software involving huge capital investment that forms a major obstacle in drug discovery projects in academic setup. We present an open source resource, FilTer BaSe- a chemoinformatics platform (http://bioinfo.net.in/filterbase/) that host fully filtered, ready to use compound libraries with workable size. The resource also hosts a database that enables efficient searching the chemical space of around 348,000 compounds on the basis of physicochemical and substructure properties. Ready to use compound libraries and database presented here is expected to aid a helping hand for new drug developers and medicinal chemists. Copyright © 2017 Elsevier Inc. All rights reserved.

Towards a full reference library of MS(n) spectra. II: A perspective from the library of pesticide spectra extracted from the literature/Internet.

Science.gov (United States)

Milman, Boris L; Zhurkovich, Inna K

2011-12-30

To gain perspective on building full transferable libraries of MS(n) spectra from their diverse/numerous collections, a new library was built from 1723 MS(>1) spectra (mainly MS² spectra) of 490 pesticides and related compounds. Spectra acquired on different types of tandem instruments in various experimental conditions were extracted from 168 literature articles and Internet sites. Testing of the library was based on searches where 'unknown' and reference spectra originated from different sources (mainly from different laboratories) were cross-compared. The NIST 05 MS² library was added to the reference spectra. The library searches were performed with all the test spectra or were divided into different subsamples containing (a) various numbers of replicate spectra of test compounds or (b) spectra acquired from different instrument types. Thus, the dependence of true/false search (identification) result rates on different factors was explored. The percentage of 1st rank correct identifications (true positives) for the only 'unknown' mass spectrum and two and more reference spectra and matching precursor ion m/z values was 89%. For qualified matches, above the cut-off match factor, that rate decreased to 80%. The corresponding rates based on the best match for two and more 'unknown' and reference spectral replicates were 89-94%. For quadrupole instruments, the rates were even higher: 91-95% (one 'unknown' spectrum) and 90-100% (two and more such spectra). This study shows that MS² spectral libraries generated from the numerous literature/Internet sources are not less efficient for the goal of identification of unknown compounds including pesticides than very common EI-MS¹ libraries and are almost as efficient as the most productive from current MS² spectral databases. Such libraries may be used as individual reference databases or supplements to large experimental spectral collections covering many groups of abundant compounds and different types of tandem

Description of problem or function: MARS-ORNL is a selection of computer codes for the generation of problem-dependent multigroup cross section libraries. They are selected modules from the AMPX-2 system for AMPX interface format libraries, LASL codes for CCCC interfaces, and processing codes for libraries to be used by ANISN, DOT, or MORSE codes. The codes in the collection are used in connection with the following DLC data libraries: ZZ-LIB-IV (DLC-0040), ZZ-VITAMIN-C (DLC-0041), VITAMIN-4C (DLC-0053), ZZ-CLEAR/42B (DLC-0042), ZZ-CSRL/43B (DLC-0043), and EPRMASTER (DLC-0052). The functions of these processing codes are briefly described: A. AMPX Modules: AIM: Converts AMPX Master Interface Files from EBCDIC to binary form and back. AJAX: Merges, collects, assembles, re-orders, joins, and copies selected nuclides from AMPX Master Interfaces. BONAMI: Accesses Bondarenko factors from an AMPX Master Library and performs resonance self-shielding calculations. CHOX: Produces a coupled interface library in AMPX format by combining neutron libraries (generated by module XLACS), gamma libraries (generated by module SMUG), and photon production libraries (generated by module LAPHNGAS). CHOXM: Combines self-shielding factors as generated by the code SPHINX (PSR-0129) and an infinite dilution neutron master interface (generated by XLACS) to generate a self-shielded neutron AMPX Interface File. The interface produced by CHOXM is an input to the NITAWL module of AMPX. CHOXM is a modified version of CHOX. COMAND: Collapses ANISN cross section libraries. DIAL: Produces edits from AMPX Master Interfaces. ICE-II: Accepts cross sections from an AMPX working library and produces mixed cross sections in four formats: (1) AMPX working library format; (2) ANISN format; (3) group-independent ANISN format; (4) Monte Carlo processed cross section library format. NITAWL: Produces self-shielded and working cross section libraries in the formats required by the ANISN, DOT, or MORSE codes

The U.S. Nuclear Regulatory Commission's Regulatory Guide 1.190 states that calculational methods used to estimate reactor pressure vessel (RPV) fluence should use the latest version of the evaluated nuclear data file (ENDF). The VITAMIN-B6 fine-group library and BUGLE-96 broad-group library, which are widely used for RPV fluence calculations, were generated using ENDF/B-VI.3 data, which was the most current data when Regulatory Guide 1.190 was issued. We have developed new fine-group (VITAMIN-B7) and broad-group (BUGLE-B7) libraries based on ENDF/B-VII.0. These new libraries, which were processed using the AMPX code system, maintain the same group structures as the VITAMIN-B6 and BUGLE-96 libraries. Verification and validation of the new libraries were accomplished using diagnostic checks in AMPX, 'unit tests' for each element in VITAMIN-B7, and a diverse set of benchmark experiments including critical evaluations for fast and thermal systems, a set of experimental benchmarks that are used for SCALE regression tests, and three RPV fluence benchmarks. The benchmark evaluation results demonstrate that VITAMIN-B7 and BUGLE-B7 are appropriate for use in RPV fluence calculations and meet the calculational uncertainty criterion in Regulatory Guide 1.190.

The Joint Evaluated Fission and Fusion (JEFF) Project is a collaborative effort among the member countries of the NEA Data Bank to develop a reference nuclear data library. The JEFF library contains sets of evaluated nuclear data, mainly for fission and fusion applications; it contains a number of different data types, including neutron and proton interaction data, radioactive decay data, fission yield data, thermal scattering law data and photo-atomic interaction data. The latest version of the JEFF library, JEFF-3.1, was released by the NEA in May 2005. JEFF-3.1 combines the efforts of the JEFF and EFF/EAF (European Fusion File/European Activation File) working groups who have contributed to this combined fission and fusion library. The neutron general purpose library contains incident neutron data for 381 materials from 1 H to 255 Fm. The activation library (based on the European Activation File, EAF-2003) contains 774 different targets from 1 H to 257 Fm. The radioactive decay data library contains data for 3 852 isotopes, of which 226 are stable. The proton special purpose library contains incident proton data for 26 materials from 40 Ca to 209 Bi. The thermal scattering law library covers 9 materials, and the fission yield library covers 19 isotopes of neutron induced fission yield from 232 Th to 245 Cm and 3 isotopes with spontaneous fission yields ( 242 Cm, 244 Cm and 252 Cf)

The academic library network

Full Text Available The efficiency of libraries, academic libraries in particular, necessitates organizational changes facilitating or even imposing co-operation. Any structure of any university has to have an integrated network of libraries, with an appropriate division of work, and one that is consolidated as much as it is possible into medium-size or large libraries. Within thus created network, a chance arises to centralize the main library processes based on appropriate procedures in the main library, highly specialized, more effective and therefore cheaper in operation, including a co-ordination of all more important endeavours and tasks. Hierarchically subordinated libraries can be thus more focused on performing their routine service, more and more frequently providing for the whole of the university, and being able to adjust to changeable requirements and demands of patrons and of new tasks resulting from the new model of the university operation. Another necessary change seems to be a universal implementation of an ov rall programme framework that would include all services in the university’s library networks.

Novel search algorithms for a mid-infrared spectral library of cotton contaminants.

During harvest, a variety of plant based contaminants are collected along with cotton lint. The USDA previously created a mid-infrared, attenuated total reflection (ATR), Fourier transform infrared (FT-IR) spectral library of cotton contaminants for contaminant identification as the contaminants have negative impacts on yarn quality. This library has shown impressive identification rates for extremely similar cellulose based contaminants in cases where the library was representative of the samples searched. When spectra of contaminant samples from crops grown in different geographic locations, seasons, and conditions and measured with a different spectrometer and accessories were searched, identification rates for standard search algorithms decreased significantly. Six standard algorithms were examined: dot product, correlation, sum of absolute values of differences, sum of the square root of the absolute values of differences, sum of absolute values of differences of derivatives, and sum of squared differences of derivatives. Four categories of contaminants derived from cotton plants were considered: leaf, stem, seed coat, and hull. Experiments revealed that the performance of the standard search algorithms depended upon the category of sample being searched and that different algorithms provided complementary information about sample identity. These results indicated that choosing a single standard algorithm to search the library was not possible. Three voting scheme algorithms based on result frequency, result rank, category frequency, or a combination of these factors for the results returned by the standard algorithms were developed and tested for their capability to overcome the unpredictability of the standard algorithms' performances. The group voting scheme search was based on the number of spectra from each category of samples represented in the library returned in the top ten results of the standard algorithms. This group algorithm was able to identify

Review the International Campaign to Revitalise Academic Medicine (ICRAM) Future Scenarios as a potential starting point for developing scenarios to envisage plausible futures for health sciences libraries. At an educational workshop, 15 groups, each composed of four to seven Association of Academic Health Sciences Libraries (AAHSL) directors and AAHSL/NLM Fellows, created plausible stories using the five ICRAM scenarios. Participants created 15 plausible stories regarding roles played by health sciences librarians, how libraries are used and their physical properties in response to technology, scholarly communication, learning environments and health care economic changes. Libraries are affected by many forces, including economic pressures, curriculum and changes in technology, health care delivery and scholarly communications business models. The future is likely to contain ICRAM scenario elements, although not all, and each, if they come to pass, will impact health sciences libraries. The AAHSL groups identified common features in their scenarios to learn lessons for now. The hope is that other groups find the scenarios useful in thinking about academic health science library futures.

Full Text Available We described the beginnings of the Auersperg Prince’s Library of Ljubljana. The special concern was put on the most important bibliophile among the Auerpergs, Volk Engelbert. The work of his friend and librarian, Schönleben, was put in the limelight. We researched the catalogue of Auersperg’s mathematical books, including astronomy and discussed the importance and value of particular items. The library was used as the base for the analysis of Auersperg’s scientific interests just after they returned to the Catholic faith. We also examined their opinion about Copernicus. The contemporary destiny of the Auersperg Prince’s Library was mentioned. In this very moment just some books of the former Ljubljanian library could be traced in different foreign libraries, especially in USA. We discovered the second edition of Copernicus’ De Revolutionibus which National and University Library of Ljubljana inherited from the Ljubljanian Jesuit library. Because of the wrong year written in Cobiss record, this precious treasure was unknown to the researchers up to now.

The survey statements included a combination of conclusions based on selections from school library research studies, and the Information Literacy Standards for Student Learning from the merican Association of School Librarians’ nformation Power: Building Partnerships or Learning. The two surveys were used to triangulate multiple sources of data to illustrate the “helps” provided by the school library to student learning. Students were also given the opportunity to describe “helps” in their own words in an open‐ended critical incident question. Main results – The data showed that the selected effective school libraries were perceived as providing ‘helps’ in dynamic ways that appeared to have a transformative effect on student learning. School libraries and librarians were viewed as having an active role in the learning process. Of the students surveyed, 99.4 % believed that school libraries helped them become better learners. The results were grouped into seven blocks of ‘help’ concepts that frame the contributions of the school library and the school librarian to student learning (Table 1.

2012-01-01

This paper details the generation of neutron data libraries for the CASMO5 lattice physics code based on the recently released JENDL-4.0 and ENDF/B-VII.1beta4 nuclear data evaluations. This data represents state-of-the-art nuclear data for late-2011. The key features of the new evaluations are briefly described along with the procedure for processing of this data into CASMO5, 586-energy group neutron data libraries. Finally some CASMO5 results for standard UO 2 and MOX critical experiments for the two new libraries and the current ENDF/B-VII.0 CASMO5 library are presented including the B and W 1810 series, DIMPLE S06A, S06B, TCA reflector criticals with iron plates and the PNL-30-35 MOX criticals. The results show that CASMO5 with the new libraries is performing well for these criticals with a very slight edge in results to the JENDL-4.0 nuclear data evaluation over the ENDF/B-VII.1beta4 evaluation. Work is currently underway to generate a CASMO5 library based on the final ENDF/B-VII.R1 evaluation released Dec. 22, 2011. (authors)

Lu, Minjie; Hamamura, Takeshi; Doosje, Bertjan; Suzuki, Satoko; Takemura, Kosuke

2017-08-01

Group-based emotions are experienced when individuals are engaged in emotion-provoking events that implicate the in-group. This research examines the complexity of group-based emotions, specifically a concurrence of positive and negative emotions, focusing on the role of dialecticism, or a set of folk beliefs prevalent in Asian cultures that views nature and objects as constantly changing, inherently contradictory, and fundamentally interconnected. Study 1 found that dialecticism is positively associated with the complexity of Chinese participants' group-based emotions after reading a scenario depicting a positive intergroup experience. Study 2 found that Chinese participants experienced more complex group-based emotions compared with Dutch participants in an intergroup situation and that this cultural difference was mediated by dialecticism. Study 3 manipulated dialecticism and confirmed its causal effect on complex group-based emotions. These studies also suggested the role of a balanced appraisal of an intergroup situation as a mediating factor.

Strategic marketing planning in library

Karmen Štular-Sotošek

2000-01-01

Full Text Available The article is based on the idea that every library can design instruments for creating events and managing the important resources of today's world, especially to manage the changes. This process can only be successful if libraries use adequate marketing methods. Strategic marketing planning starts with the analysis of library's mission, its objectives, goals and corporate culture. By analysing the public environment, the competitive environment and the macro environment, libraries recognise their opportunities and threats. These analyses are the foundations for library definitions: What does the library represent?, What does it aspire to? Which goals does it want to reach? What kind of marketing strategy will it use for its target market?

Structure-based virtual screening was applied to design combinatorial libraries to discover novel and potent soluble epoxide hydrolase (sEH) inhibitors. X-ray crystal structures revealed unique interactions for a benzoxazole template in addition to the conserved hydrogen bonds with the catalytic machinery of sEH. By exploitation of the favorable binding elements, two iterations of library design based on amide coupling were employed, guided principally by the docking results of the enumerated virtual products. Biological screening of the libraries demonstrated as high as 90% hit rate, of which over two dozen compounds were single digit nanomolar sEH inhibitors by IC(50) determination. In total the library design and synthesis produced more than 300 submicromolar sEH inhibitors. In cellular systems consistent activities were demonstrated with biochemical measurements. The SAR understanding of the benzoxazole template provides valuable insights into discovery of novel sEH inhibitors as therapeutic agents.

Full Text Available Objective – To develop a set of generic outcome-based performance measures for Irishhospital libraries.Methods – Various models and frameworks of performance measurement were used as atheoretical paradigm to link the impact of library services directly with measurablehealthcare objectives and outcomes. Strategic objectives were identified, mapped toperformance indicators, and finally translated into response choices to a single-questiononline survey for distribution via email.Results – The set of performance indicators represents an impact assessment tool whichis easy to administer across a variety of healthcare settings. In using a model directlyaligned with the mission and goals of the organization, and linked to core activities andoperations in an accountable way, the indicators can also be used as a channel throughwhich to implement action, change, and improvement.Conclusion – The indicators can be adopted at a local and potentially a national level, asboth a tool for advocacy and to assess and improve service delivery at a macro level. Toovercome the constraints posed by necessary simplifications, substantial further research is needed by hospital libraries to develop more sophisticated and meaningful measures of impact to further aid decision making at a micro level.

THEWASP library. Thermodynamic water and steam properties library in GPU

International Nuclear Information System (INIS)

Waintraub, M.; Lapa, C.M.F.; Mol, A.C.A.; Heimlich, A.

2011-01-01

In this paper we present a new library for thermodynamic evaluation of water properties, THEWASP. This library consists of a C++ and CUDA based programs used to accelerate a function evaluation using GPU and GPU clusters. Global optimization problems need thousands of evaluations of the objective functions to nd the global optimum implying in several days of expensive processing. This problem motivates to seek a way to speed up our code, as well as to use MPI on Beowulf clusters, which however increases the cost in terms of electricity, air conditioning and others. The GPU based programming can accelerate the implementation up to 100 times and help increase the number of evaluations in global optimization problems using, for example, the PSO or DE Algorithms. THEWASP is based on Water-Steam formulations publish by the International Association for the properties of water and steam, Lucerne - Switzerland, and provides several temperature and pressure function evaluations, such as specific heat, specific enthalpy, specific entropy and also some inverse maps. In this study we evaluated the gain in speed and performance and compared it a CPU based processing library. (author)

2012-12-01

Full Text Available As part of its Library Spaces Business Plan initiative, for four weeks in early 2012 Edmonton Public Library (EPL conducted a survey of its customers about how they use the library’s spaces and what they want from their library spaces. Using both print and online versions, the survey received 1517 responses which collected both quantitative and qualitative data. Findings revealed the ongoing importance of collections and quiet in library spaces, as well as the growing importance of providing social and group space in the library. Results of the survey indicate EPL’s customers do not consider the spaces a separate aspect from the collections and services the library provides. The results of the survey also emphasized the importance of regularly consulting with customers about library spaces to ensure the spaces continue to fulfill their needs as the role of the library, and the space needs associated with it, evolve.

The TRIPOLI-3 code uses multigroup nuclear data libraries generated using the NJOY-THEMIS suite of modules: for neutrons, they are produced from the ENDF/B-VI evaluations and cover the range between 20 MeV and 10{sup -5} eV, either in 315 groups and for one temperature, or in 3209 groups and for five temperatures; for gamma-rays, they are from JEF2 and are processed in groups between 14 MeV and keV. The probability tables used for the neutron transport calculations have been derived from the ENDF/B-VI evaluations using the CALENDF code. Cross sections for gamma production by neutron interaction (fission, capture or inelastic scattering) have been derived from ENDF/B-VI in 315 neutron groups and 75 gamma groups. The code also uses two response function libraries: for neutrons; based on several sources, in particular the dosimetry libraries IRDF/85 and IRDF/90; for gamma-rays it is based on the JEF2 evaluation and contains the kerma factors for all the elements and cross sections for all interactions.

Khan, M.J.H.; Sarker, M.M.; Islam, S.M.A.

2013-01-01

Highlights: ► To validate the SRAC2006 code system for TRIGA neutronics calculations. ► TRX and BAPL lattices are treated as standard benchmarks for this purpose. ► To compare the calculated results with experiment as well as MCNP values in this study. ► The study demonstrates a good agreement with the experiment and the MCNP results. ► Thus, this analysis reflects the validation study of the SRAC2006 code system. - Abstract: The goal of this study is to present the validation study of the SRAC2006 code system based on evaluated nuclear data libraries ENDF/B-VII.0 and JENDL-3.3 for neutronics analysis of TRIGA Mark-II Research Reactor at AERE, Bangladesh. This study is achieved through the analysis of integral parameters of TRX and BAPL benchmark lattices of thermal reactors. In integral measurements, the thermal reactor lattices TRX-1, TRX-2, BAPL-UO 2 -1, BAPL-UO 2 -2 and BAPL-UO 2 -3 are treated as standard benchmarks for validating/testing the SRAC2006 code system as well as nuclear data libraries. The integral parameters of the said lattices are calculated using the collision probability transport code PIJ of the SRAC2006 code system at room temperature 20 °C based on the above libraries. The calculated integral parameters are compared to the measured values as well as the MCNP values based on the Chinese evaluated nuclear data library CENDL-3.0. It was found that in most cases, the values of integral parameters demonstrate a good agreement with the experiment and the MCNP results. In addition, the group constants in SRAC format for TRX and BAPL lattices in fast and thermal energy range respectively are compared between the above libraries and it was found that the group constants are identical with very insignificant difference. Therefore, this analysis reflects the validation study of the SRAC2006 code system based on evaluated nuclear data libraries JENDL-3.3 and ENDF/B-VII.0 and can also be essential to implement further neutronics calculations

Libraries as 'everyday' settings: the Glasgow MCISS project.

Whitelaw, Sandy; Coburn, Jonathan; Lacey, Marion; McKee, Martin J; Hill, Carol

2017-10-01

A settings-based approach is now well-established in health promotion, initially undertaken in conventional places like schools and workplaces, but more recently being expressed in a wider range of what Torp et al. call 'everyday' settings. In this context, libraries have emerged as another potential setting whose ubiquity and accessibility suggests that they may be particularly effective in addressing health inequalities. Drawing on a case study-the Glasgow Macmillan Cancer Information and Support Services Library project-this paper reports on the potential for seeing 'libraries as settings' and in the context of a set of associated theoretical resources, specifically scrutinizes the nature of initiative implementation. Data were drawn from multiple sources: semi-structured interviews and focus groups with strategic partners and stakeholders, operational staff, project volunteers, service users and members of the general public. Qualitative data were complemented by quantitative insights from surveys with members of the partnership, libraries staff and volunteers. Despite some concerns associated with potentially hostile cultural and financial contexts that might threaten longer term sustainability, insights suggested that in pragmatic terms, the project was attracting sizable 'footfall' and successfully addressing a range of needs. Additionally, the formal implementation processes associated with project implementation were considered to have been highly successful in embedding the model into the library culture. In summary, there is evidence that libraries have the potential to be considered as supportive settings and could act as a model for an emergent vision of what libraries do. © The Author 2016.

Hopkins, Emily

2017-06-01

Knowledge management has seen something of a resurgence in attention amongst health librarians recently. Of course it has never ceased to exist, but now many library staff are becoming more involved in organisational knowledge management, and positioning themselves as key players in the sphere. No single model of knowledge management is proliferating, but approaches that best fit the organisation's size, structure and culture, and a blending of evidence based practice and knowledge sharing. Whatever it is called and whatever models are used, it's clear that for librarians and information professionals, the importance of putting knowledge and evidence into practice, sharing knowledge well and capturing it effectively, are still what we will continue to do. © 2017 Health Libraries Group.

Library 3.0 intelligent libraries and apomediation

CERN Document Server

Kwanya, Tom; Underwood, Peter

2015-01-01

The emerging generation of research and academic library users expect the delivery of user-centered information services. 'Apomediation' refers to the supporting role librarians can give users by stepping in when users need help. Library 3.0 explores the ongoing debates on the "point oh” phenomenon and its impact on service delivery in libraries. This title analyses Library 3.0 and its potential in creating intelligent libraries capable of meeting contemporary needs, and the growing role of librarians as apomediators. Library 3.0 is divided into four chapters. The first chapter introduces and places the topic in context. The second chapter considers "point oh” libraries. The third chapter covers library 3.0 librarianship, while the final chapter explores ways libraries can move towards '3.0'.

A Fragment-Based Method of Creating Small-Molecule Libraries to Target the Aggregation of Intrinsically Disordered Proteins.

Joshi, Priyanka; Chia, Sean; Habchi, Johnny; Knowles, Tuomas P J; Dobson, Christopher M; Vendruscolo, Michele

2016-03-14

The aggregation process of intrinsically disordered proteins (IDPs) has been associated with a wide range of neurodegenerative disorders, including Alzheimer's and Parkinson's diseases. Currently, however, no drug in clinical use targets IDP aggregation. To facilitate drug discovery programs in this important and challenging area, we describe a fragment-based approach of generating small-molecule libraries that target specific IDPs. The method is based on the use of molecular fragments extracted from compounds reported in the literature to inhibit of the aggregation of IDPs. These fragments are used to screen existing large generic libraries of small molecules to form smaller libraries specific for given IDPs. We illustrate this approach by describing three distinct small-molecule libraries to target, Aβ, tau, and α-synuclein, which are three IDPs implicated in Alzheimer's and Parkinson's diseases. The strategy described here offers novel opportunities for the identification of effective molecular scaffolds for drug discovery for neurodegenerative disorders and to provide insights into the mechanism of small-molecule binding to IDPs.

Neutron cross-section libraries in the AMPX master interface format have been created for three reactor types. Included are an 84-group library for use with light-water reactors, a 27-group library for use with heavy-water CANDU reactors and a 126-group library for use with liquid metal fast breeder reactors. In general, ENDF/B data were used in the creation of these libraries, and the nuclides included in each library should be sufficient for most neutronic analyses of reactors of that type. Each library has been used successfully in fuel depletion calculations

ESI-MS is a well established technique for the study of biopolymers (nucleic acids, proteins) and their non covalent adducts, due to its capacity to detect ligand-target complexes in the gas phase and allows inference of ligand-target binding in solution. In this article we used this approach to investigate the interaction of ligands to the Heat Shock Protein 90 (Hsp90). This enzyme is a molecular chaperone involved in the folding and maturation of several proteins which has been subjected in the last years to intensive drug discovery efforts due to its key role in cancer. In particular, reference compounds, with a broad range of dissociation constants from 40pM to 100μM, were tested to assess the reliability of ESI-MS for the study of protein-ligand complexes. A good agreement was found between the values measured with a fluorescence polarization displacement assay and those determined by mass spectrometry. After this validation step we describe the setup of a medium throughput screening method, based on ESI-MS, suitable to explore interactions of therapeutic relevance biopolymers with chemical libraries. Our approach is based on an automated flow injection ESI-MS method (AFI-MS) and has been applied to screen the Nerviano Medical Sciences proprietary fragment library of about 2000 fragments against Hsp90. In order to discard false positive hits and to discriminate those of them interacting with the N-terminal ATP binding site, competition experiments were performed using a reference inhibitor. Gratifyingly, this group of hits matches with the ligands previously identified by NMR FAXS techniques and confirmed by X-ray co-crystallization experiments. These results support the use of AFI-MS for the screening of medium size libraries, including libraries of small molecules with low affinity typically used in fragment based drug discovery. AFI-MS is a valid alternative to other techniques with the additional opportunities to identify compounds interacting with

2014-04-01

Full Text Available The purpose of this paper is to determine and describe the library culture in Croatian public libraries. Semi-structured interviews with 14 library directors (ten public and four academic were conducted. The tentative discussion topics were: definition of quality, responsibility for quality, satisfaction with library services, familiarization with user perspective of library and librarians, monitoring of user expectations and opinions. These interviews incorporate some of the findings of the project Evaluation of library and information services: public and academic libraries. The project investigates library culture in Croatian public and academic libraries and their preparedness for activities of performance measurement. The interviews reveal that library culture has changed positively in the past few years and that library leaders have positive attitude towards quality and evaluation activities. Library culture in Croatian libraries is a relatively new concept and as such was not actively developed and/or created. This article looks into the library culture of Croatian libraries, but at the same time investigates whether there is any trace of culture of assessment in them. Also, this article brings the latest update on views, opinions and atmosphere in Croatian public and academic libraries.

CSBB-ConeExclusion, adapting structure based solution virtual screening to libraries on solid support.

Shave, Steven; Auer, Manfred

2013-12-23

Combinatorial chemical libraries produced on solid support offer fast and cost-effective access to a large number of unique compounds. If such libraries are screened directly on-bead, the speed at which chemical space can be explored by chemists is much greater than that addressable using solution based synthesis and screening methods. Solution based screening has a large supporting body of software such as structure-based virtual screening tools which enable the prediction of protein-ligand complexes. Use of these techniques to predict the protein bound complexes of compounds synthesized on solid support neglects to take into account the conjugation site on the small molecule ligand. This may invalidate predicted binding modes, the linker may be clashing with protein atoms. We present CSBB-ConeExclusion, a methodology and computer program which provides a measure of the applicability of solution dockings to solid support. Output is given in the form of statistics for each docking pose, a unique 2D visualization method which can be used to determine applicability at a glance, and automatically generated PyMol scripts allowing visualization of protein atom incursion into a defined exclusion volume. CSBB-ConeExclusion is then exemplarically used to determine the optimum attachment point for a purine library targeting cyclin-dependent kinase 2 CDK2.

Comparative analysis of machine learning methods in ligand-based virtual screening of large compound libraries.

Science.gov (United States)

Ma, Xiao H; Jia, Jia; Zhu, Feng; Xue, Ying; Li, Ze R; Chen, Yu Z

2009-05-01

Machine learning methods have been explored as ligand-based virtual screening tools for facilitating drug lead discovery. These methods predict compounds of specific pharmacodynamic, pharmacokinetic or toxicological properties based on their structure-derived structural and physicochemical properties. Increasing attention has been directed at these methods because of their capability in predicting compounds of diverse structures and complex structure-activity relationships without requiring the knowledge of target 3D structure. This article reviews current progresses in using machine learning methods for virtual screening of pharmacodynamically active compounds from large compound libraries, and analyzes and compares the reported performances of machine learning tools with those of structure-based and other ligand-based (such as pharmacophore and clustering) virtual screening methods. The feasibility to improve the performance of machine learning methods in screening large libraries is discussed.

An in silico MS/MS library for automatic annotation of novel FAHFA lipids.

Science.gov (United States)

Ma, Yan; Kind, Tobias; Vaniya, Arpana; Gennity, Ingrid; Fahrmann, Johannes F; Fiehn, Oliver

2015-01-01

A new lipid class named 'fatty acid esters of hydroxyl fatty acids' (FAHFA) was recently discovered in mammalian adipose tissue and in blood plasma and some FAHFAs were found to be associated with type 2 diabetes. To facilitate the automatic annotation of FAHFAs in biological specimens, a tandem mass spectra (MS/MS) library is needed. Due to the limitation of the commercial available standard compounds, we proposed building an in silico MS/MS library to extend the coverage of molecules. We developed a computer-generated library with 3267 tandem mass spectra (MS/MS) for 1089 FAHFA species. FAHFA spectra were generated based on authentic standards with negative mode electrospray ionization and 10, 20, and 40 V collision induced dissociation at 4 spectra/s as used in in ultra-high performance liquid chromatography-QTOF mass spectrometry studies. However, positional information of the hydroxyl group is only obtained either at lower QTOF spectra acquisition rates of 1 spectrum/s or at the MS(3) level in ion trap instruments. Therefore, an additional set of 4290 fragment-rich MS/MS spectra was created to enable distinguishing positional FAHFA isomers. The library was generated based on ion fragmentations and ion intensities of FAHFA external reference standards, developing a heuristic model for fragmentation rules and extending these rules to large swaths of computer-generated structures of FAHFAs with varying chain lengths, degrees of unsaturation and hydroxyl group positions. Subsequently, we validated the new in silico library by discovering several new FAHFA species in egg yolk, showing that this library enables high-throughput screening of FAHFA lipids in various biological matrices. The developed library and templates are freely available for commercial or noncommercial use at http://fiehnlab.ucdavis.edu/staff/yanma/fahfa-lipid-library. This in silico MS/MS library allows users to annotate FAHFAs from accurate mass tandem mass spectra in an easy and fast manner

A library treasure hunt – An alternative way to introduce new university students to the library

Directory of Open Access Journals (Sweden)

Kristina Holmin Verdozzi

2013-12-01

Full Text Available Introducing new students to the library and its resources during the first hectic weeks at university can pose a considerable challenge. We have to compete with many other kinds of introductory activities, making new friends, becoming acquainted with the subject, not to mention all the parties and social functions arranged for new students. The traditional lecture, or showing large groups of tired students around the library just wasn't working. So, a few years ago, we started to think about radical new ways of introducing students to the library. We hit upon the idea of arranging a treasure hunt. Students working in small groups have to carry out various tasks at different stations in different libraries. When each task has been successfully completed, a verbal report is made to the librarian at that library, and students can ask questions, before going on to the next task. By carrying out actual tasks, the students become familiar with the important aspects of library resources; learning by doing and having fun at the same time. The "treasure" at the end of the hunt was an apple, a sweet, a pencil, a small LED flashlight and information brochures about the library and the master programme in physics. One of the decisive factors in the success of this activity was the cooperation of lecturers, who integrated it into their introductory programme. It also had high status, as it was a compulsory activity, thanks to the commitment and understanding of lecturers. The treasure hunt is important in the students' later studies as they know which library resources are available, and they recognise the librarians. This lowers the threshold for the further development of the students' information gathering skills. The success of this activity in one of the subjects taught at the Department of Physics has led to the decision to make the library treasure hunt compulsory for all students at the Department, in both the Engineering Faculty and the Science

In October 1998, the National Library of Medicine (NLM) launched a pilot project to learn about the role of public libraries in providing health information to the public and to generate information that would assist NLM and the National Network of Libraries of Medicine (NN/LM) in learning how best to work with public libraries in the future. Three regional medical libraries (RMLs), eight resource libraries, and forty-one public libraries or library systems from nine states and the District of Columbia were selected for participation. The pilot project included an evaluation component that was carried out in parallel with project implementation. The evaluation ran through September 1999. The results of the evaluation indicated that participating public librarians were enthusiastic about the training and information materials provided as part of the project and that many public libraries used the materials and conducted their own outreach to local communities and groups. Most libraries applied the modest funds to purchase additional Internet-accessible computers and/or upgrade their health-reference materials. However, few of the participating public libraries had health information centers (although health information was perceived as a top-ten or top-five topic of interest to patrons). Also, the project generated only minimal usage of NLM's consumer health database, known as MEDLINEplus, from the premises of the monitored libraries (patron usage from home or office locations was not tracked). The evaluation results suggested a balanced follow-up by NLM and the NN/LM, with a few carefully selected national activities, complemented by a package of targeted activities that, as of January 2000, are being planned, developed, or implemented. The results also highlighted the importance of building an evaluation component into projects like this one from the outset, to assure that objectives were met and that evaluative information was available on a timely basis, as was

DNA-encoded chemical libraries: advancing beyond conventional small-molecule libraries.

Science.gov (United States)

Franzini, Raphael M; Neri, Dario; Scheuermann, Jörg

2014-04-15

DNA-encoded chemical libraries (DECLs) represent a promising tool in drug discovery. DECL technology allows the synthesis and screening of chemical libraries of unprecedented size at moderate costs. In analogy to phage-display technology, where large antibody libraries are displayed on the surface of filamentous phage and are genetically encoded in the phage genome, DECLs feature the display of individual small organic chemical moieties on DNA fragments serving as amplifiable identification barcodes. The DNA-tag facilitates the synthesis and allows the simultaneous screening of very large sets of compounds (up to billions of molecules), because the hit compounds can easily be identified and quantified by PCR-amplification of the DNA-barcode followed by high-throughput DNA sequencing. Several approaches have been used to generate DECLs, differing both in the methods used for library encoding and for the combinatorial assembly of chemical moieties. For example, DECLs can be used for fragment-based drug discovery, displaying a single molecule on DNA or two chemical moieties at the extremities of complementary DNA strands. DECLs can vary substantially in the chemical structures and the library size. While ultralarge libraries containing billions of compounds have been reported containing four or more sets of building blocks, also smaller libraries have been shown to be efficient for ligand discovery. In general, it has been found that the overall library size is a poor predictor for library performance and that the number and diversity of the building blocks are rather important indicators. Smaller libraries consisting of two to three sets of building blocks better fulfill the criteria of drug-likeness and often have higher quality. In this Account, we present advances in the DECL field from proof-of-principle studies to practical applications for drug discovery, both in industry and in academia. DECL technology can yield specific binders to a variety of target

MOX Cross-Section Libraries for ORIGEN-ARP

International Nuclear Information System (INIS)

Gauld, I.C.

2003-01-01

The use of mixed-oxide (MOX) fuel in commercial nuclear power reactors operated in Europe has expanded rapidly over the past decade. The predicted characteristics of MOX fuel such as the nuclide inventories, thermal power from decay heat, and radiation sources are required for design and safety evaluations, and can provide valuable information for non-destructive safeguards verification activities. This report describes the development of computational methods and cross-section libraries suitable for the analysis of irradiated MOX fuel with the widely-used and recognized ORIGEN-ARP isotope generation and depletion code of the SCALE (Standardized Computer Analyses for Licensing Evaluation) code system. The MOX libraries are designed to be used with the Automatic Rapid Processing (ARP) module of SCALE that interpolates appropriate values of the cross sections from a database of parameterized cross-section libraries to create a problem-dependent library for the burnup analysis. The methods in ORIGEN-ARP, originally designed for uranium-based fuels only, have been significantly upgraded to handle the larger number of interpolation parameters associated with MOX fuels. The new methods have been incorporated in a new version of the ARP code that can generate libraries for low-enriched uranium (LEU) and MOX fuel types. The MOX data libraries and interpolation algorithms in ORIGEN-ARP have been verified using a database of declared isotopic concentrations for 1042 European MOX fuel assemblies. The methods and data are validated using a numerical MOX fuel benchmark established by the Organization for Economic Cooperation and Development (OECD) Working Group on burnup credit and nuclide assay measurements for irradiated MOX fuel performed as part of the Belgonucleaire ARIANE International Program

2010-06-01

Existing drugs address a relatively narrow range of biological targets. As a result, libraries of drug-like molecules have proven ineffective against a variety of challenging targets, such as protein-protein interactions, nucleic acid complexes, and antibacterial modalities. In contrast, natural products are known to be effective at modulating such targets, and new libraries are being developed based on underrepresented scaffolds and regions of chemical space associated with natural products. This has led to several recent successes in identifying new chemical probes that address these challenging targets. Copyright 2010 Elsevier Ltd. All rights reserved.

2013-02-01

Full Text Available Librarians often provide students who attend one-shot library instruction sessions with research guides they can refer to once class is over. These guides, whether in paper or electronic form, serve to remind the students of key points and resources addressed during the session. It is unclear, though, if and how students refer to these guides once leaving the classroom. This article reports on the results of two focus groups made up of students who attended a basic library instruction session as part of a survey art course. The students shared how they used a paper and electronic research guide, delivered via LibGuides, and what they would like research guides to contain. The article also suggests directions for further research on the topic.

Full Text Available Objective – To investigate the perceived alignment between academic library services and high-impact practices (HIPs that affect student retention. Design – Survey questionnaire. Setting – Public comprehensive universities in the United States of America with a Carnegie classification of master’s level as of January 2013. Subjects – 68 library deans or directors out of the 271 who were originally contacted. Methods – The author used Qualtrics software to create a survey based on the HIPs, tested the survey for reliability, and then distributed it to 271 universities. Library services were grouped into 1 of 3 library scales: library collection, library instruction, or library facilities. The survey consisted of a matrix of 10 Likert-style questions addressing the perceived level of alignment between the library scales and the HIPs. Each question provided an opportunity for the respondent to enter a “brief description of support practices” (p 477. Additional demographic questions addressed the years of experience of the respondent, undergraduate student enrollment of the university, and whether librarians held faculty rank. Main Results – The author measured Pearson correlation coefficients and found a positive correlation between the library scales and the HIPs. All three library scales displayed a moderately strong positive correlation between first-year seminars and experiences (HIP 1, common intellectual experiences (HIP 2, writing-intensive courses (HIP 4, undergraduate research (HIP 6, diversity and global learning (HIP 7, service learning and community-based learning (HIP 8, internships (HIP 9, and capstone courses and projects (HIP 10.

2014-04-01

Librarians continually integrate new technologies into library services for health sciences students. Recently published data are lacking about student ownership of technological devices, awareness of new technologies, and interest in using devices and technologies to interact with the library. A survey was implemented at seven health sciences libraries to help answer these questions. Results show that librarian assumptions about awareness of technologies are not supported, and student interest in using new technologies to interact with the library varies widely. Collecting this evidence provides useful information for successfully integrating technologies into library services.

Measuring Library Vendor Cyber Security: Seven Easy Questions Every Librarian Can Ask

Directory of Open Access Journals (Sweden)

Alex Caro

2016-04-01

Full Text Available This article is based on an independent cyber security risk management audit for a public library system completed by the authors in early 2015 and based on a research paper by the same group at Clark University in 2014. We stress that while cyber security must include raising public knowledge in regard to cyber security issues and resources, and libraries are indeed the perfect place to disseminate this knowledge, librarians are also in a unique position as the gatekeepers of information services provided to the public and should conduct internal audits to ensure our content partners and IT vendors take cyber security as seriously as the library and its staff. One way to do this is through periodic reviews of existing vendor relationships. To this end, the authors created a simple grading rubric you can adopt or modify to help take this first step towards securing your library data. It is intended to be used by both technical and non-technical staff as a simple measurement of what vendor agreements currently exist and how they rank, while at the same time providing a roadmap for which security features or policy statements the library can or should require moving forward.

Carlos M. Moreno

2014-06-01

Full Text Available Group services like the audioconference require a minimum level of quality of service for multicast sessions. This work proposes a new overlay multicast architecture based on SIP extensions and a genetic algorithm. The architecture consists of a SIP Extender client (SE, a Multicast Gateway Agent (MGA and a Multicast Manager (MM. The SE receives information about the most adequate MGA for it determined by a genetic algorithm inside the MM, then connects the chosen MGA and maintains connection with the MM itself. The genetic algorithm is implemented with JGAP(Java Genetic Algorithm Package libraries. The SE and MGA are programmed with JainSIP and JainSDP libraries which contain Java structures associated with the SIP protocol and session description. Some experiments over UTP wired and WiFi IEEE802.11n network were performed. Partial results with static and dynamic MGA selection show that, if we compare the joining and leaving time measured inside a station containing SE client programmed with JainSIP and JainSDP libraries versus SJphone proprietary client, the software engineering may have more influence than the medium access method in the response time for a potential group member. Even more, the genetic algorithm at the MM minimizes the response time at great scale.

Creating a web-based digital photographic archive: one hospital library's experience.

Science.gov (United States)

Marshall, Caroline; Hobbs, Janet

2017-04-01

Cedars-Sinai Medical Center is a nonprofit community hospital based in Los Angeles. Its history spans over 100 years, and its growth and development from the merging of 2 Jewish hospitals, Mount Sinai and Cedars of Lebanon, is also part of the history of Los Angeles. The medical library collects and maintains the hospital's photographic archive, to which retiring physicians, nurses, and an active Community Relations Department have donated photographs over the years. The collection was growing rapidly, it was impossible to display all the materials, and much of the collection was inaccessible to patrons. The authors decided to make the photographic collection more accessible to medical staff and researchers by purchasing a web-based digital archival package, Omeka. We decided what material should be digitized by analyzing archival reference requests and considering the institution's plan to create a Timeline Wall documenting and celebrating the history of Cedars-Sinai. Within 8 months, we digitized and indexed over 500 photographs. The digital archive now allows patrons and researchers to access the history of the hospital and enables the library to process archival references more efficiently.

Worcestershire Health Libraries provides services to all NHS and social care staff in Worcestershire. Despite intensive marketing, statistics showed low usage of the library service for professions allied to technical services and allied health professionals. To discover why there was low usage of the library services using qualitative techniques and to use focus groups as a marketing opportunity. This article also aims to outline the processes involved in delivering focus groups, the results gained, and the actions taken in response to the results. Focus groups were conducted in two departments, Pathology and Occupational Therapy. The Biochemistry department (part of Pathology) had two focus groups. An additional focus group was conducted for all the Pathology education leads. Occupational Therapy had two meetings, one for hospital based staff, and the other for community staff. Issues centred on registration, inductions, time, library ambience, multi-disciplinary service and resources. The findings raised marketing opportunities and the process identified potential candidates for the role of team knowledge officer, to act as library champions within departments. It also identified areas in which the library service was not meeting user needs and expectations, and helped focus service development. Focus groups allowed an opportunity to speak to non-users face to face and to discover, and where appropriate challenge both their, and library staff's pre-conceived ideas about the service. The information revealed gave an opportunity to market services based on user needs. © 2011 The authors. Health Information and Libraries Journal © 2011 Health Libraries Group.

Generation and testing of the shielding data library EURLIB for fission and fusion technology

1977-01-01

For the common field of core physics and shielding, the CSEWG group structure of 239 fast neutron groups had been proposed, of which the 100 neutron groups of the EURLIB Library is a sub-set for shielding. This standard group Library EURLIB had been initiated by the NEA-specialist group on shielding benchmarks in 1974. The wide acceptance of the Library for interpretation of benchmarks in the NEA program represents an important step forward in the standardization of group data which is the basic requirement for a useful collaboration. On the other side the interpretation of a series of different benchmark experiments with the EURLIB Library provides the best check of the cross section data for neutron and gamma-rays showing the needs for further improvements. The paper describes the joint work of IKE, Stuttgart and EURATOM, Ispra in generating multigroup libraries for neutron and gamma-rays. Special effort has been devoted to improve the flux weighting for both types of radiation and proper treatment of thermal neutrons. The coupled multigroup Library of 100 neutron and 20 gamma groups is collapsed into few group structures for typical designs of LWR, LMFBR, gas cooled and thermonuclear reactors. The work for optimal few group representation is done in cooperation with EIR, Wurenlingen. The testing of the EURLIB Library is a common effort of several institutions participating in the NEA shielding benchmark program

UFMGLIB: a multigroup library for the WIMS code

Aboustta, Mohamed A.; Mello, Jair Carlos

1995-01-01

The British code WIMS is distributed by the NEA in its D4 version. It has a proper data library (Standard Library) in 69 energy groups covering, in its 1981 version, more than 100 materials with sufficient details. The Standard library was generated, basically, from the UKNDL data files and has been submitted to many alterations since the 1960's. Completely new versions such as the WIMKAL 88, generated from the basic library ENDF/B-V, were introduced and are available from the IAEA. The library UFMGLIB was generated from the ENDF/B-VI basic data library with some of the Standard data being maintained. The library contains evaluations for 131 different materials including the most common in thermal reactors. Results obtained from running the WIMS-D4 code with this library compare very well with results from the other libraries when running benchmark cases. This paper shows a general description of the library and some of the steps taken to generate it. (author). 12 refs, 2 tabs

A letter describing the study and with an invitation to fill out an online questionnaire was sent to all students in the sample. There were 1,694 valid responses (approximately 35% response rate. Students following short vocational programs were deemed to be under‐represented and these subjects were omitted from the analysis of this report,which reflects the response of 1,575 students. The online questionnaire gathered demographic details (gender, age, educational institution, study topic, study year, geographical location, access to the Internet, etc. and used 110 questions or statements to gather information about student information‐seeking behaviour related to study purposes. These included use of the physical library and satisfaction with services, use of search engines, awareness and use of library Web‐based services, study behaviour, and participation in information literacy activities. Main results – For the purposes of this study, “academic library is used as a generic term covering university libraries, research libraries, educational libraries and all other kind of libraries outside the field of public libraries” (p. 278. The survey results confirmed many of the previous international reports of student information‐seeking behaviour: 85% of students use the academic library for study purposes; fewer than 10% of all students are able to cope without any library use; students in technology and engineering

Biomathematical Description of Synthetic Peptide Libraries

Trepel, Martin

2015-01-01

Libraries of randomised peptides displayed on phages or viral particles are essential tools in a wide spectrum of applications. However, there is only limited understanding of a library's fundamental dynamics and the influences of encoding schemes and sizes on their quality. Numeric properties of libraries, such as the expected number of different peptides and the library's coverage, have long been in use as measures of a library's quality. Here, we present a graphical framework of these measures together with a library's relative efficiency to help to describe libraries in enough detail for researchers to plan new experiments in a more informed manner. In particular, these values allow us to answer-in a probabilistic fashion-the question of whether a specific library does indeed contain one of the "best" possible peptides. The framework is implemented in a web-interface based on two packages, discreteRV and peptider, to the statistical software environment R. We further provide a user-friendly web-interface called PeLiCa (Peptide Library Calculator, http://www.pelica.org), allowing scientists to plan and analyse their peptide libraries. PMID:26042419

1979-01-01

The US Department of Energy Office of Fusion Energy and the Division of Reactor Research and Technology jointly sponsored the development of a coupled fine-group cross section library (VITAMIN-C). The experience gained in the generation, validation, and utilization of the VITAMIN-C library along with its broad range of applicability has led to the request for updating this data set using ENDF/B-V. Additional support in this regard has been provided by the Defense Nuclear Agency (DNA) and by EPRI in support of weapons analyses and light water reactor shielding and dosimetry problems, respectively. The rationale for developing the multipurpose ENDF/B-V-based VITAMIN-E library is presented, with special emphasis on new models used in the data generation algorithms. The library specifications and testing procedures are also discussed in detail. The distribution of the VITAMIN-E library is currently subject to the same restrictions as the distribution of the ENDF/B-V data. 2 tables

Use of CPXSD for generation of effective fast multigroup libraries for pressure vessel fluence calculations

International Nuclear Information System (INIS)

Alpan, F. Arzu; Haghighat, Alireza

2008-01-01

Multigroup (i.e., broad-group) libraries play a significant role in the accuracy of transport calculations. There are several broad-group libraries available for particular applications. For example the 47-neutron (26 fast groups), 20-gamma-group BUGLE libraries are commonly used for light water reactor shielding and pressure vessel dosimetry problems. However, there is no publicly available methodology to construct group structures for a problem and objective of interest. Therefore, we have developed the Contribution and Point-wise Cross-Section Driven (CPXSD) methodology, which constructs effective fine-and broad-group structures. In this paper, we use the CPXSD methodology to construct broad-group structures for fast neutron dosimetry problems. It is demonstrated that the broad-group libraries generated from CPXSD constructed group structures, while only 14 groups (rather than 26 groups) in the fast energy range are in good agreement (similar to 1 %-2 %) with the fine-group library from which they were derived, in reaction rate calculations.

This paper reports on the development of a tool for searching the contents of licensed full-text electronic book (e-book) collections. The Health Sciences Library System (HSLS) provides services to the University of Pittsburgh's medical programs and large academic health system. The HSLS has developed an innovative tool for federated searching of its e-book collections. Built using the XML-based Vivísimo development environment, the tool enables a user to perform a full-text search of over 2,500 titles from the library's seven most highly used e-book collections. From a single "Google-style" query, results are returned as an integrated set of links pointing directly to relevant sections of the full text. Results are also grouped into categories that enable more precise retrieval without reformulation of the search. A heuristic evaluation demonstrated the usability of the tool and a web server log analysis indicated an acceptable level of usage. Based on its success, there are plans to increase the number of online book collections searched. This library's first foray into federated searching has produced an effective tool for searching across large collections of full-text e-books and has provided a good foundation for the development of other library-based federated searching products.

Data at Risk and Research Libraries

Research libraries have recently engaged in data rescue events amidst growing concerns about access to federal data sets. While these efforts are well intentioned, libraries run the risk of ignoring a long established history of activities and accomplishments by other communities focused on data at risk, many of which are represented at forums such as AGU. Under the auspices of the Data Conservancy, the Sheridan Libraries at Johns Hopkins University hosted an event in July 2017 that convened members of various communities including ESIP, RDA, Data Rescue Boulder, Association of Research Libraries, the Fedora repository platform, the Open Science Framework and the Interplanetary File System or IPFS (via the Data Together Network). This group identified a potential role for research libraries to partner with existing players in the data at risk community by focusing on a distributed preservation network as part of a coordinated collection development program. This session will offer an opportunity to hear about this potential role for research libraries and to provide feedback about its viability and utility.

JSSTDL-300 multi-group cross section library with 300 neutron energy groups coupled with 104 group γ-ray cross sections was developed for general users in nuclear reactor physics and/or design, whose source data is the evaluated nuclear data library JENDL-3.2. For the purpose of a standard or common use, several famous cross section libraries worldwide used, i.e., ABBN-25, GAM-123, VITAMIN-C/J(E+C), MGCL-137, BERMUDA-12 and FNS-125 for neutron, and LANL-12, -24-, -48, and CSEWG-94 for γ-ray, are consulted about setting the common energy group structure. Furthermore, in order to expand the applicability, the top energy is set on 20 MeV and the lowest energy is 10 -5 eV. In the thermal neutron energy region, the JSSTDL-300 has about 20 energy groups. Besides, many utility codes for group collapsing and for data format transformation are provided for general users. (author)

Health sciences libraries building survey, 1999-2009.

Ludwig, Logan

2010-04-01

A survey was conducted of health sciences libraries to obtain information about newer buildings, additions, remodeling, and renovations. An online survey was developed, and announcements of survey availability posted to three major email discussion lists: Medical Library Association (MLA), Association of Academic Health Sciences Libraries (AAHSL), and MEDLIB-L. Previous discussions of library building projects on email discussion lists, a literature review, personal communications, and the author's consulting experiences identified additional projects. Seventy-eight health sciences library building projects at seventy-three institutions are reported. Twenty-two are newer facilities built within the last ten years; two are space expansions; forty-five are renovation projects; and nine are combinations of new and renovated space. Six institutions report multiple or ongoing renovation projects during the last ten years. The survey results confirm a continuing migration from print-based to digitally based collections and reveal trends in library space design. Some health sciences libraries report loss of space as they move toward creating space for "community" building. Libraries are becoming more proactive in using or retooling space for concentration, collaboration, contemplation, communication, and socialization. All are moving toward a clearer operational vision of the library as the institution's information nexus and not merely as a physical location with print collections.

Nowadays, computational approaches are an integral part of life science research. Problems related to interpretation of experimental results, data analysis, or visualization tasks highly benefit from the achievements of the digital era. Simulation methods facilitate predictions of physicochemical properties and can assist in understanding macromolecular phenomena. Here, we will give an overview of the methods developed in our group that aim at supporting researchers from all life science areas. Based on state-of-the-art approaches from structural bioinformatics and cheminformatics, we provide software covering a wide range of research questions. Our all-in-one web service platform ProteinsPlus (http://proteins.plus) offers solutions for pocket and druggability prediction, hydrogen placement, structure quality assessment, ensemble generation, protein-protein interaction classification, and 2D-interaction visualization. Additionally, we provide a software package that contains tools targeting cheminformatics problems like file format conversion, molecule data set processing, SMARTS editing, fragment space enumeration, and ligand-based virtual screening. Furthermore, it also includes structural bioinformatics solutions for inverse screening, binding site alignment, and searching interaction patterns across structure libraries.

ANSL-V: ENDF/B-V based multigroup cross-section libraries for Advanced Neutron Source (ANS) reactor studies. Supplement 1

Energy Technology Data Exchange (ETDEWEB)

Wright, R.Q.; Renier, J.P.; Bucholz, J.A.

1995-08-01

The original ANSL-V cross-section libraries (ORNL-6618) were developed over a period of several years for the physics analysis of the ANS reactor, with little thought toward including the materials commonly needed for shielding applications. Materials commonly used for shielding applications include calcium barium, sulfur, phosphorous, and bismuth. These materials, as well as {sup 6}Li, {sup 7}Li, and the naturally occurring isotopes of hafnium, have been added to the ANSL-V libraries. The gamma-ray production and gamma-ray interaction cross sections were completely regenerated for the ANSL-V 99n/44g library which did not exist previously. The MALOCS module was used to collapse the 99n/44g coupled library to the 39n/44g broad- group library. COMET was used to renormalize the two-dimensional (2- D) neutron matrix sums to agree with the one-dimensional (1-D) averaged values. The FRESH module was used to adjust the thermal scattering matrices on the 99n/44g and 39n/44g ANSL-V libraries. PERFUME was used to correct the original XLACS Legendre polynomial fits to produce acceptable distributions. The final ANSL-V 99n/44g and 39n/44g cross-section libraries were both checked by running RADE. The AIM module was used to convert the master cross-section libraries from binary coded decimal to binary format (or vice versa).

Structure-based virtual screening of molecular libraries as cdk2 inhibitors

International Nuclear Information System (INIS)

Riaz, U.; Khaleeq, M.

2011-01-01

CDK2 inhibitor is an important target in multiple processes associated with tumor growth and development, including proliferation, neovascularization, and metastasis. In this study, hit identification was performed by virtual screening of commercial and in-house compound libraries. Docking studies for the hits were performed, and scoring functions were used to evaluate the docking results and to rank ligand-binding affinities. Subsequently, hit optimization for potent and selective candidate CDK2 inhibitors was performed through focused library design and docking analyses. Consequently, we report that a novel compound with an IC50 value of 89 nM, representing 2-Amino-4,6-di-(4',6'-dibromophenyl)pyrimidine 1, is highly selective for CDK2 inhibitors. The docking structure of compound 1 with CDK2 inhibitor disclosed that the NH moiety and pyrimidine ring appeared to fit tightly into the hydrophobic pocket of CDK2 inhibitor. Additionally, the pyrimidine NH forms a hydrogen bond with the carboxyl group of Asp348. These results confirm the successful application of virtual screening studies in the lead discovery process, and suggest that our novel compound can be an effective CDK2 inhibitor candidate for further lead optimization.

Sensitivity of 238U resonance absorption to library multigroup structure as calculated by WIMS-AECL

International Nuclear Information System (INIS)

Laughton, P.J.; Donnelly, J.V.

1995-01-01

In simulations of the TRX-1 experimental lattice, WIMS-AECL overpredicts, relative to MCNP, resonance absorption in neutron-energy groups containing the three large, low-lying resonances of 238 U when a standard ENDF/B-V-based library is used. A total excess in these groups of 4.0 neutron captures by 238 U per thousand fission neutrons has been observed. Similar comparisons are made in this work for the MIT-4 experimental lattice and simplified CANDU lattice cells containing 37-element fuel, with and without heavy-water coolant. Eleven different 89-group cross-section libraries were constructed for WIMS-AECL from ENDF/B-V data: only the neutron-energy-group boundaries used in generating multigroup cross sections and the Goldstein-Cohen correction factors differ from one library to the next. The first library uses the original 89-group structure, and the other ten involve energy groups of varying widths centred on the three large, low-lying resonances of 238 U. For TRX-1, some reduction in total discrepancy in 238 U capture can be achieved by using a new structure, although the improvement is small. The discrepancies in 238 U capture are of the same order for the MIT-4 case as those observed for TRX-1 for both the original group structure and the ten new structures. The WIMS-AECL calculation of 238 U resonance absorption in the same ranges of energy for the simplified CANDU 37-element lattice are in better agreement with MCNP than they are for TRX-1 and MIT-4: when the original structure is used, WIMS-AECL underpredicts total capture rate by 238 U in the energy range of interest by only 0.56 per thousand fission neutrons (coolant present) and 0.88 per thousand fission neutrons (voided coolant channel). The discrepancies are reduced when some of the new structures are used. For almost all of the cases considered here-TRX-1, MIT-4 and CANDU with coolant-better group-by-group agreement of 238 U capture around the 6.67-eV resonance is achieved by using a new library

Update of KASHIL-E6 library for shielding analysis and benchmark calculations

2004-01-01

For various shielding and reactor pressure vessel dosimetry applications, a pseudo-problem-independent neutron-photon coupled MATXS-format library based on the last release of ENDF/B-VI has been generated as a part of the update program for KASHIL-E6, which was based on ENDF/B-VI.5. It has VITAMIN-B6 neutron and photon energy group structures, i.e., 199 groups for neutron and 42 groups for photon. The neutron and photon weighting functions and the Legendre order of scattering are same as KASHIL-E6. The library has been validated through some benchmarks: the PCA-REPLICA and NESDIP-2 experiments for LWR pressure vessel facility benchmark, the Winfrith Iron88 experiment for validation of iron data, and the Winfrith Graphite experiment for validation of graphite data. These calculations were performed by the TRANSXlDANTSYS code system. In addition, the substitutions of the JENDL-3.3 and JEFF-3.0 data for Fe, Cr, Cu and Ni, which are very important nuclides for shielding analyses, were investigated to estimate the effects on the benchmark calculation results

Distance education and students at branch campuses were not included. From this pool, 949 usable survey responses (29% of the sample were collected. The respondent demographics proved to be reasonably equivalent to those of the total undergraduate population in terms of class standing (freshman, sophomore, junior, or senior and academic discipline.Methods – The study consisted of three phases. In phase one, an email invitation with a link to the four‐item multiple choice online survey was sent to students in the sample population. Results were analyzed using Pearson chi‐square tests to determine goodness of fit between the following variables: class standing and library visits, class standing and virtual library use, academic college and library visits, and academic college and virtual library use.When significant dependence was detected, researchers examined relationships between the specific groups (e.g., freshman and sophomore and library use, and also compared each group to one another using odds ratios and by constructing 95% confidence intervals.Phase two was intended to gather qualitative information from the 275 infrequent or non‐users of the library in focus groups. However, researchers invited the 95 students in this group who had indicated a willingness to be contacted for further study, and only five students participated. The author therefore does not report on this limited data.In phase three, researchers

An Evidence Based Methodology to Facilitate Public Library Non-fiction Collection Development

Directory of Open Access Journals (Sweden)

Matthew Kelly

2015-12-01

Full Text Available Objective – This research was designed as a pilot study to test a methodology for subject based collection analysis for public libraries. Methods – WorldCat collection data from eight Australian public libraries was extracted using the Collection Evaluation application. The data was aggregated and filtered to assess how the sample’s titles could be compared against the OCLC Conspectus subject categories. A hierarchy of emphasis emerged and this was divided into tiers ranging from 1% of the sample. These tiers were further analysed to quantify their representativeness against both the sample’s titles and the subject categories taken as a whole. The interpretive aspect of the study sought to understand the types of knowledge embedded in the tiers and was underpinned by hermeneutic phenomenology. Results – The study revealed that there was a marked tendency for a small percentage of subject categories to constitute a large proportion of the potential topicality that might have been represented in these types of collections. The study also found that distribution of the aggregated collection conformed to a Power Law distribution (80/20 so that approximately 80% of the collection was represented by 20% of the subject categories. The study also found that there were significant commonalities in the types of subject categories that were found in the designated tiers and that it may be possible to develop ontologies that correspond to the collection tiers. Conclusions – The evidence-based methodology developed in this pilot study has the potential for further development to help to improve the practice of collection development. The introduction of the concept of the epistemic role played by collection tiers is a promising aid to inform our understanding of knowledge organization for public libraries. The research shows a way forward to help to link subjective decision making with a scientifically based approach to managing knowledge

Full Text Available From major tasks—such as recruitment of new students and staff—to the more mundane but equally important tasks—such as providing directions to campus—college and university Web sites perform a wide range of tasks for a varied assortment of users. Overlapping functions and user needs meld to create the need for a Web site with three major functions: promotion and marketing, access to online services, and providing a means of communication between individuals and groups. In turn, college and university Web sites that provide links to their library home page can be valuable assets for recruitment, public relations, and for helping users locate online services.

Bruno, Ian J.; Cole, Jason C.; Lommerse, Jos P. M.; Rowland, R. Scott; Taylor, Robin; Verdonk, Marcel L.

1997-11-01

Crystallographic and theoretical (ab initio) data on intermolecular nonbondedinteractions have been gathered together in a computerised library('IsoStar`). The library contains information about the nonbonded contactsformed by some 250 chemical groupings. The data can be displayed visually andused to aid protein-ligand docking or the identification of bioisostericreplacements. Data from the library show that there is great variability inthe geometrical preferences of different types of hydrogen bonds, although ingeneral there is a tendency for H-bonds to form along lone-pair directions.The H-bond acceptor abilities of oxygen and sulphur atoms are highly dependenton intramolecular environments. The nonbonded contacts formed by manyhydrophobic groups show surprisingly strong directional preferences. Manyunusual nonbonded interactions are to be found in the library and are ofpotential value for designing novel biologically active molecules.

2014-06-01

This article is only the second in the Dissertations into Practice series to highlight the role of public libraries in health information. It is the result of an investigation into the provision of health information in East Sussex Library and Information Service, which formed the basis of Anneliese Ingham's dissertation for her MA in Information Studies at the University of Brighton. At the time Anneliese was doing her research, the service was experimenting with different ways of providing healthcare information at one of its main libraries, and they were interested in the impact of this. The provision of health information to the public is one of my own research interests, and I was Anneliese's dissertation supervisor. I thought she produced a very good piece of work, and the results she highlights in this article are applicable to all public library authorities. Anneliese graduated with an MA in 2012 and worked for East Sussex Library and Information Service, which she joined whilst she was still studying. AM. © 2014 The authors.

Data Analysis Methods for Library Marketing

Science.gov (United States)

Minami, Toshiro; Kim, Eunja

Our society is rapidly changing to information society, where the needs and requests of the people on information access are different widely from person to person. Library's mission is to provide its users, or patrons, with the most appropriate information. Libraries have to know the profiles of their patrons, in order to achieve such a role. The aim of library marketing is to develop methods based on the library data, such as circulation records, book catalogs, book-usage data, and others. In this paper we discuss the methodology and imporatnce of library marketing at the beginning. Then we demonstrate its usefulness through some examples of analysis methods applied to the circulation records in Kyushu University and Guacheon Library, and some implication that obtained as the results of these methods. Our research is a big beginning towards the future when library marketing is an unavoidable tool.

Educational services in health sciences libraries: an analysis of the periodical literature, 1975-1986.

Science.gov (United States)

Zachert, M J

1987-07-01

The periodical literature on group instructional services in health sciences libraries was analyzed to determine the nature of these services, their target audiences, and their institutional settings. Three kinds of reports were identified: descriptions of services (70%), reviews of the literature (10.5%), and future-oriented articles that advocate various group instructional services (19.5%). Five target audiences were identified: library users, staff, librarian peers, library science students, and patients. Instructional services were offered primarily in medical school/center libraries, hospital libraries, and the National Library of Medicine and its Regional Medical Libraries (RMLs). To a lesser extent, health sciences educational services are offered through other professional school libraries, library associations and consortia, and schools of library science. There are gaps in the literature in the areas of library experience with marketing, evaluation, administration of the offered educational services, and continuing education for health sciences librarians.

Assessing users satisfaction with service quality in Slovenian public library

Directory of Open Access Journals (Sweden)

Igor Podbrežnik

2016-07-01

Full Text Available Purpose: A research was made into user satisfaction with regard to the quality of library services in one of the Slovenian public libraries. The aim was to establish the type of service quality level actually expected by the users, and to determine their satisfaction with the current quality level of available library services.Methodology: The research was performed by means of the SERVQUAL measuring tool which was used to determine the size and direction of the gap between the detected and the expected quality of library services among public library users.Results: Different groups of users provide different assessments of specific quality factors, and a library cannot satisfy the expectations of each and every user if most quality factors display discrepancies between the estimated perception and expectations. The users expect more reliable services and more qualified library staff members who would understand and allocate time for each user’s individual needs. The largest discrepancies from the expectations are detected among users in the under-35 age group and among the more experienced and skilled library users. The results of factor analysis confirm the fact that a higher number of quality factors can be explained by three common factors affecting the satisfaction of library users. A strong connection between user satisfaction and their assessment of the integral quality of services and loyalty has been established.Research restrictions: The research results should not be generalised and applied to all Slovenian public libraries since they differ in many important aspects. In addition, a non-random sampling method was used.Research originality/Applicability: The conducted research illustrates the use of a measuring tool that was developed with the aim of determining the satisfaction of users with the quality of library services in Slovenian public libraries. Keywords: public library, user satisfaction, quality of library services, user

An Emerging Theory for Evidence Based Information Literacy Instruction in School Libraries, Part 2: Building a Culture of Inquiry

Directory of Open Access Journals (Sweden)

Carol A. Gordon

2009-09-01

Full Text Available Objective – The purpose of this paper is to articulate a theory for the use of action research as a tool of evidence based practice for information literacy instruction in school libraries. The emerging theory is intended to capture the complex phenomenon of information skills teaching as it is embedded in school curricula. Such a theory is needed to support research on the integrated approach to teaching information skills and knowledge construction within the framework of inquiry learning. Part 1 of this paper, in the previous issue, built a foundation for emerging theory, which established user‐centric information behavior and constructivist learning theory as the substantive theory behind evidence based library instruction in schools. Part 2 continues to build on the Information Search Process and Guided Inquiry as foundational to studying the information‐to‐knowledge connection and the concepts of help and intervention characteristic of 21st century school library instruction.Methods – This paper examines the purpose and methodology of action research as a tool of evidence based instruction. This is accomplished through the explication of three components of theory‐building: paradigm, substantive research, and metatheory. Evidence based practice is identified as the paradigm that contributes values and assumptions about school library instruction. It establishes the role of evidence in teaching and learning, linking theory and practice. Action research, as a tool of evidence based practice is defined as the synthesis of authentic learning, or performance‐based assessment practices that continuously generate evidence throughout the inquiry unit of instruction and traditional data collection methods typically used in formal research. This paper adds social psychology theory from Lewin’s work, which contributes methodology from Gestalt psychology, field theory, group dynamics, and change theory. For Lewin the purpose of action

2012-02-01

Full Text Available Ghadir Program has been developed to make direct access to academic universities’ resources. This program has been implemented in Ministry of Science, Research and Education by Iranian Research Institute for Information Science and Technology as the coordinating centre since 1999 in 240 libraries after a period of pilot run. After a couple of days, it was necessary to assess the quality of this program to make changes if required. Therefore, here the results of assessing the quality of services provided by the coordinating center from the viewpoint of participant libraries were presented. Servqual applied as the base for this quality assessment. The population of this research was the entire participants which consist of 240 libraries affiliated to 66 universities and research centers. The questionnaire as the research instrument was sent to the libraries’ managers and they were asked to give them to Ghadir Program agents to fill it as well. As the result, among the questionnaires returned form 131 libraries, 178 ones were analyzable. The satisfaction of participant libraries from the services received and the gap between these services and their expectations from the coordinating center was investigated. According to the findings, the satisfaction of libraries from this center was more than average (3.5 from 5. In the Servqual dimensions, empathy and responsiveness had the maximum and reliability had the minimum gap between services received and expectations from the coordinating center.
