Crack growth determination on laboratory components

International Nuclear Information System (INIS)

Hurst, R.C.

1993-01-01

In order to aid design and support remanent life assessment of plant components operating at elevated temperatures, the reliability of the analytical methods, which translate materials data procured from the laboratory to the behaviour of actual components, requires validation. Such a validation can of course be interpreted from operating plant, however the potential risks involved encourage the development of out of plant techniques for the validation of representative components. For meaningful validation, these techniques need careful control and high accuracy which can best be achieved in a laboratory environment. As the laboratory component test should be designed to simulate actual plant conditions as closely as possible, the direct extension of the results to the plant component case requires scaling up. Consequently the successful development of such a test may even lead to the advantageous situation where it could form an alternative to the conventional route where, for example, it may not be possible to obtain the plant component's metallurgical structure in a conventional specimen or, alternatively, when too many assumptions are required in the analysis when translating to different geometries and stress systems. Under these conditions, in spite of the more sophisticated test requirements, it may prove more reasonable to opt for the more representative laboratory component data for use in design or lifetime prediction. The present work describes the application of the component validation test philosophy to the problem of crack growth under two rather different loading conditions. In both cases, crack growth is measured using the direct current potential drop (PD) technique on tubular metallic components containing artificial defects, however the plant conditions to be simulated lead to either creep or thermal fatigue. The creep studies on Alloy 800H support heat exchanger design for nuclear plant, solar towers and chemical plant, whereas the work on the

Azotobacter chroococcum TRA2, an isolate of wheat rhizosphere displayed plant growth promoting attributes including indole acetic acid, HCN, siderophore production, solubilization of inorganic phosphate and fixation of atmospheric nitrogen. In addition, it showed strong antagonistic effect against Macrophomina phaseolina and Fusarium oxysporum. It also caused degradation and digestion of cell wall components, resulting in hyphal perforations, empty cell (halo) formation, shrinking and lysis of fungal mycelia along with significant degeneration of conidia. Fertilizer adaptive variant strain of A. chroococcum TRA2 was studied with Tn5 induced streptomycin resistant transconjugants of wild type tetracycline-resistant TRA2 (designated TRA2(tetra+strep+)) after different durations. The strain was significantly competent in rhizosphere, as its population increased by 15.29 % in rhizosphere of Sesamum indicum. Seed bacterization with the strain TRA2 resulted in significant increase in vegetative growth parameters and yield of sesame over the non-bacterized seeds. However, application of TRA2 with half dose of fertilizers showed sesame yield almost similar to that obtained by full dose treatment. Moreover, the oil yield increased by 24.20 %, while protein yield increased by 35.92 % in treatment receiving half dose of fertilizer along with TRA2 bacterized seeds, as compared to untreated control.

Quorum-dependent transfer of the opine-catabolic plasmid pAoF64/95 is regulated by a novel mechanism involving inhibition of the TraR antiactivator TraM.

Science.gov (United States)

Wetzel, Margaret E; Asenstorfer, Robert E; Tate, Max E; Farrand, Stephen K

2018-04-10

We previously described a plasmid of Agrobacterium spp., pAoF64/95, in which the quorum-sensing system that controls conjugative transfer is induced by the opine mannopine. We also showed that the quorum-sensing regulators TraR, TraM, and TraI function similarly to their counterparts in other repABC plasmids. However, traR, unlike its counterpart on Ti plasmids, is monocistronic and not located in an operon that is inducible by the conjugative opine. Here, we report that both traR and traM are expressed constitutively and not regulated by growth with mannopine. We report two additional regulatory genes, mrtR and tmsP, that are involved in a novel mechanism of control of TraR activity. Both genes are located in the distantly linked region of pAoF64/95 encoding mannopine utilization. MrtR, in the absence of mannopine, represses the four-gene mocC operon as well as tmsP, which is the distal gene of the eight-gene motA operon. As judged by a bacterial two-hybrid analysis, TmsP, which shows amino acid sequence relatedness with the TraM-binding domain of TraR, interacts with the antiactivator. We propose a model in which mannopine, acting through the repressor MrtR, induces expression of TmsP which then titrates the levels of TraM thereby freeing TraR to activate the tra regulon. © 2018 The Authors.

This study presents an analysis of photometric light curves and absolute parameters for the EW-type binary V336 TrA. VRI imaging observations were taken in 2013 by using the robotic telescopes PROMPT 4 and PROMPT 5 at Cerro Tololo Inter-American Observatory (CTIO), Chile. The observed light curves were fitted by using the Wilson-Devinney method. The results showed that V336 TrA is a W-type contact binary with a mass ratio of q = 1.396. The binary is a weak contact system with a fill-out factor of f = 15.69%. The system contains components with masses of 0.653 M⊙ and 0.912 M⊙ for the hotter and the cooler, respectively. The location of the secondary (less massive) component on the log M - log L diagram was found to be near the TAMS. The component has evolved to be oversize and overluminous. The orbital angular momentum of the binary was found to be log Jo = 51.61 cgs, less than all detached systems for same mass. The system has undergone angular momentum and/or mass loss, during the binary evolution from the detached to contact system.

Jane Austen: tra brand e desiderio

Triggering the formation of the supergiant H II region NGC 604 in M 33

Formation mechanism of a supergiant H II region NGC 604 is discussed in terms of collision of H I clouds in M 33. An analysis of the archival H I data obtained with the Very Large Array (VLA) reveals complex velocity distributions around NGC 604. The H I clouds are composed of two velocity components separated by ˜20 km s-1 for an extent of ˜700 pc, beyond the size of the the H II region. Although the H I clouds are not easily separated in velocity with some mixed component represented by merged line profiles, the atomic gas mass amounts to 6 × 106 M_{⊙} and 9 × 106 M_{⊙} for each component. These characteristics of H I gas and the distributions of dense molecular gas in the overlapping regions of the two velocity components suggest that the formation of giant molecular clouds and the following massive cluster formation have been induced by the collision of H I clouds with different velocities. Referring to the existence of a gas bridging feature connecting M 33 with M 31 reported by large-scale H I surveys, the disturbed atomic gas possibly represents the result of past tidal interaction between the two galaxies, which is analogous to the formation of the R 136 cluster in the LMC.

Full Text Available Em agosto de 1999, produtores de tomate e brássicas do Núcleo Rural da Taquara tiveram seus cultivos seriamente comprometidos devido à impossibilidade de controle da traça-do-tomateiro e da traça-das-crucíferas. Diversos inseticidas, alguns com o mesmo princípio ativo ou pertencentes ao mesmo grupo químico, eram aplicados de uma a sete vezes por semana sem qualquer eficiência no controle das pragas. Lavouras foram abandonadas em diferentes estádios de desenvolvimento. A fim de definir uma estratégia de controle que viabilizasse a produção de tomate e brássicas na região, foi avaliado em laboratório a eficiência da dose comercial de alguns inseticidas usados no controle das duas pragas. Para isso, foram coletadas duas populações de traça-do-tomateiro e uma população de traça-das-crucíferas. Para traça-do-tomateiro, cartap, abamectin, lufenuron, acefate e deltametrina causaram respectivamente 100, 90, 67, 2 e 0% de mortalidade das larvas. Para traça-das-crucíferas, B. thuringiensis, abamectin, cartap, acefate and deltametrina causaram 100; 96; 86; 79 e 5% de mortalidade respectivamente.

Abbreviated sampling and analysis plan for planning decontamination and decommissioning at Test Reactor Area (TRA) facilities

International Nuclear Information System (INIS)

1994-10-01

The objective is to sample and analyze for the presence of gamma emitting isotopes and hazardous constituents within certain areas of the Test Reactor Area (TRA), prior to D and D activities. The TRA is composed of three major reactor facilities and three smaller reactors built in support of programs studying the performance of reactor materials and components under high neutron flux conditions. The Materials Testing Reactor (MTR) and Engineering Test Reactor (ETR) facilities are currently pending D/D. Work consists of pre-D and D sampling of designated TRA (primarily ETR) process areas. This report addresses only a limited subset of the samples which will eventually be required to characterize MTR and ETR and plan their D and D. Sampling which is addressed in this document is intended to support planned D and D work which is funded at the present time. Biased samples, based on process knowledge and plant configuration, are to be performed. The multiple process areas which may be potentially sampled will be initially characterized by obtaining data for upstream source areas which, based on facility configuration, would affect downstream and as yet unsampled, process areas. Sampling and analysis will be conducted to determine the level of gamma emitting isotopes and hazardous constituents present in designated areas within buildings TRA-612, 642, 643, 644, 645, 647, 648, 663; and in the soils surrounding Facility TRA-611. These data will be used to plan the D and D and help determine disposition of material by D and D personnel. Both MTR and ETR facilities will eventually be decommissioned by total dismantlement so that the area can be restored to its original condition

Hot laboratory design on the basis of standardized components

International Nuclear Information System (INIS)

Cadrot, J.

1976-01-01

The paper describes the principal effects on hot laboratory design brought about over the last 15 years by the use of standardized components developed jointly with the CEA and the industrial associates of AFINE. After a rapid survey of the various advantages of standardization, the author turns to the specific case of a laboratory producing mixed plutonium and uranium oxide fuels, giving a brief description of the glove-boxes and ancillary equipment. He then deals with the design of an isotope production laboratory. The basic component is the DR 200 standard cell, which permits the civil engineering work to be effected on modular principles. Use of a safety-flow pressure regulating valve makes possible pneumatic automation of the production-cell internals. A substantial gain in output is the result. In the next section the paper refers to a pilot facility for irradiated fuel studies, and describes the components used, which require taking into account the high activities and intense radiations encountered in studies of this type. The author then demonstrates the flexibility with which standardized components can be adapted to different uses, thus solving many distinct problems, an example of which is represented by a semi-hot box for handling up to 100g of americium-241. Finally, the paper offers a rapid summary of the effects of standardization at the various stages concerned, from initial design to the commissioning of a hot laboratory. (author)

Unique Helicase Determinants in the Essential Conjugative TraI Factor from Salmonella enterica Serovar Typhimurium Plasmid pCU1

Energy Technology Data Exchange (ETDEWEB)

McLaughlin, Krystle J.; Nash, Rebekah P.; Redinbo, Mathew R. (UNC)

2014-06-16

The widespread development of multidrug-resistant bacteria is a major health emergency. Conjugative DNA plasmids, which harbor a wide range of antibiotic resistance genes, also encode the protein factors necessary to orchestrate the propagation of plasmid DNA between bacterial cells through conjugative transfer. Successful conjugative DNA transfer depends on key catalytic components to nick one strand of the duplex DNA plasmid and separate the DNA strands while cell-to-cell transfer occurs. The TraI protein from the conjugative Salmonella plasmid pCU1 fulfills these key catalytic roles, as it contains both single-stranded DNA-nicking relaxase and ATP-dependent helicase domains within a single, 1,078-residue polypeptide. In this work, we unraveled the helicase determinants of Salmonella pCU1 TraI through DNA binding, ATPase, and DNA strand separation assays. TraI binds DNA substrates with high affinity in a manner influenced by nucleic acid length and the presence of a DNA hairpin structure adjacent to the nick site. TraI selectively hydrolyzes ATP, and mutations in conserved helicase motifs eliminate ATPase activity. Surprisingly, the absence of a relatively short (144-residue) domain at the extreme C terminus of the protein severely diminishes ATP-dependent strand separation. Collectively, these data define the helicase motifs of the conjugative factor TraI from Salmonella pCU1 and reveal a previously uncharacterized C-terminal functional domain that uncouples ATP hydrolysis from strand separation activity.

TRAIL induces apoptosis in a variety of tumorigenic and transformed cell lines, but not in many normal cells. Recent studies have demonstrated that death receptor 5 (DR5), one of the two death receptors bound by TRAIL, showed expression in most malignantly transformed cells. This study evaluated effects of a monoclonal antibody (TRA-8) to human death receptor 5, combined with ionizing radiation, on radioresistant human larynx squamous carcinoma cell line (Hep-2R). Cells were treated with TRA-8 alone or in combination with radiation, cell viability inhibition was measured by MTT assay, and the induction of apoptosis was determined by Annexin V staining. Radionsensitivity of Hep-2R cells treated with TRA-8 were investigated with long-term clonogenic assays. Regulation of DR5 expression in cells after radiation was analyzed by indirect immunofluorescence using murine TRA-8 in combination with flow cytometry. The results suggested that TRA-8 enhanced radionsensitivity of Hep-2R cells, and that TRA-8 regulated Hep-2R cell cycle arrest at G2/M phase. Irradiation up-regulated the expression of DR5, and when combined with TRA-8 yielded optimal survival benefit. Therefore, TRA-8 can be used in combination with irradiation in radioresistant human larynx squamous carcinoma cells. Monoclonal antibodies such as TRA-8 may play an important role in the development of an effective treatment strategy for patients with radioresistant cancers.

Full Text Available Nonostante la diffusione del paradigma della smart city sia stata esponenziale, con l’effetto di confonderne il significato, il concetto di “città intelligente” indica comunque un tema di ricerca importante, in particolare quando venga esteso a contesti territoriali più ampi. In questo senso, la ricerca La smart region tra Torino e Milano. I servizi mobili come driver di innovazione territoriale in vista di Expo 2015 (Politecnico di Milano-Telecom Italia si propone di sperimentare l’uso delle ICT per un sistema integrato di servizi nel territorio tra Torino e Milano, anche in prospettiva di Expo 2015: una regione metropolitana valorizzata da un sistema di relazioni già attive e inserita nel contesto più ampio della city-region del Nord Italia, il cui sviluppo va legato ad una strategia di scala vasta, declinabile nella definizione di “smart city-region” o, più semplicemente, di “smart region”. In tale contesto, il ruolo delle università nei processi di sviluppo territoriale, il miglioramento dei servizi materiali e immateriali erogati dai campus, su cui la ricerca (in corso ha scelto di concentrarsi, può contribuire ad aumentare la sostenibilità e competitività del territorio. Una prima sperimentazione è stata condotta sull’area di Città Studi a Milano, testando una metodologia utile a comprenderne le esigenze e individuando soluzioni e servizi funzionanti su  terminali di comunicazione mobile, interfaccia tra persone e luoghi nel campus e nel contesto urbano circostante.

Giocare, tra violenza ed ecologia della mente.

2008-07-01

Full Text Available L'articolo riflette sulle relazioni tra comunicazione, violenza e gioco, nel tentativo di rintracciare tra loro convergenze, affinità e contrasti. Le nostre relazioni, infatti, ci immettono inerzialmente in dilemmi e paradossi di così alta complessità da rendere spesso inadeguati gli strumenti 'logici' ed 'analitici': dal che può derivare un senso di impotenza, rabbia, paralisi, ma anche un desiderio potente di controllo e di soluzione degli eventi. Entrambe queste strade ci conducono dentro le false alternative della violenza. La cultura del gioco, invece, ci propone (attraverso le sue pratiche, ma anche negli scritti teorici di Freud, Winnicott, Bateson, qui riassunti e rivisitati una modalità più creativa e nonviolenta, più prossima ad un' ecologia della mente e ad un'estetica delle emozioni.

Validation of the dermal exposure model in ECETOC TRA.

Marquart, Hans; Franken, Remy; Goede, Henk; Fransman, Wouter; Schinkel, Jody

2017-08-01

The ECETOC TRA model (presently version 3.1) is often used to estimate worker inhalation and dermal exposure in regulatory risk assessment. The dermal model in ECETOC TRA has not yet been validated by comparison with independent measured exposure levels. This was the goal of the present study. Measured exposure levels and relevant contextual information were gathered via literature search, websites of relevant occupational health institutes and direct requests for data to industry. Exposure data were clustered in so-called exposure cases, which are sets of data from one data source that are expected to have the same values for input parameters in the ECETOC TRA dermal exposure model. For each exposure case, the 75th percentile of measured values was calculated, because the model intends to estimate these values. The input values for the parameters in ECETOC TRA were assigned by an expert elicitation and consensus building process, based on descriptions of relevant contextual information.From more than 35 data sources, 106 useful exposure cases were derived, that were used for direct comparison with the model estimates. The exposure cases covered a large part of the ECETOC TRA dermal exposure model. The model explained 37% of the variance in the 75th percentiles of measured values. In around 80% of the exposure cases, the model estimate was higher than the 75th percentile of measured values. In the remaining exposure cases, the model estimate may not be sufficiently conservative.The model was shown to have a clear bias towards (severe) overestimation of dermal exposure at low measured exposure values, while all cases of apparent underestimation by the ECETOC TRA dermal exposure model occurred at high measured exposure values. This can be partly explained by a built-in bias in the effect of concentration of substance in product used, duration of exposure and the use of protective gloves in the model. The effect of protective gloves was calculated to be on average a

Expression of Tra2β in Cancer Cells as a Potential Contributory Factor to Neoplasia and Metastasis

Directory of Open Access Journals (Sweden)

Andrew Best

2013-01-01

Full Text Available The splicing regulator proteins SRSF1 (also known as ASF/SF2 and SRSF3 (also known as SRP20 belong to the SR family of proteins and can be upregulated in cancer. The SRSF1 gene itself is amplified in some cancer cells, and cancer-associated changes in the expression of MYC also increase SRSF1 gene expression. Increased concentrations of SRSF1 protein promote prooncogenic splicing patterns of a number of key regulators of cell growth. Here, we review the evidence that upregulation of the SR-related Tra2β protein might have a similar role in cancer cells. The TRA2B gene encoding Tra2β is amplified in particular tumours including those of the lung, ovary, cervix, stomach, head, and neck. Both TRA2B RNA and Tra2β protein levels are upregulated in breast, cervical, ovarian, and colon cancer, and Tra2β expression is associated with cancer cell survival. The TRA2B gene is a transcriptional target of the protooncogene ETS-1 which might cause higher levels of expression in some cancer cells which express this transcription factor. Known Tra2β splicing targets have important roles in cancer cells, where they affect metastasis, proliferation, and cell survival. Tra2β protein is also known to interact directly with the RBMY protein which is implicated in liver cancer.

Hirshorn, Steven; Jefferies, Sharon

2016-01-01

The material in this report covers the results on the NASA-wide TRA team, who are responsible for ascertaining the full extent of issues and ambiguities pertaining to TRATRL and to provide recommendations for mitigation. The team worked for approximately 6 months to become knowledgeable on the current TRATRL process and guidance and to derive recommendations for improvement.The team reviewed the TRA processes of other government agencies (OGA), including international agencies, and found that while the high-level processes are similar, the NASA process has a greater level of detail. Finally, NASA’s HQ OCT continues to monitor the GAO’s efforts to produce a TRA Best Practices Guide, a draft of which was received in February 2016. This Guide could impact the recommendations of this report.

Crystal structures of the F and pSLT plasmid TraJ N-terminal regions reveal similar homodimeric PAS folds with functional interchangeability

Energy Technology Data Exchange (ETDEWEB)

Lu, Jun; Wu, Ruiying; Adkins, Joshua N.; Joachimiak, Andrzej; Glover, Mark

2014-09-16

In the F-family of conjugative plasmids, TraJ is an essential transcriptional activator of the tra operon that encodes most of the proteins required for conjugation. Here we report for the first time the X-ray crystal structures of the TraJ N-terminal regions from the prototypic F plasmid (TraJF11-130) and from the Salmonella virulence plasmid pSLT (TraJpSLT 1-128). Both proteins form similar homodimeric Per-ARNT-Sim (PAS) fold structures. Mutational analysis reveals that the observed dimeric interface is critical for TraJF transcriptional activation, indicating that dimerization of TraJ is required for its in vivo function. An artificial ligand (oxidized dithiothreitol) occupies a cavity in the TraJF dimer interface, while a smaller cavity in corresponding region of the TraJpSLT structure lacks a ligand. Gas chromatography/mass spectrometry-electron ionization analysis of dithiothreitol-free TraJF suggests indole may be the natural TraJ ligand; however, disruption of the indole biosynthetic pathway does not affect TraJF function. Heterologous PAS domains from pSLT and R100 TraJ can functionally replace the TraJF PAS domain, suggesting that TraJ allelic specificity is mediated by the region C-terminal to the PAS domain.

Identification of evolutionarily conserved exons as regulated targets for the splicing activator tra2β in development.

Directory of Open Access Journals (Sweden)

Sushma Grellscheid

2011-12-01

Full Text Available Alternative splicing amplifies the information content of the genome, creating multiple mRNA isoforms from single genes. The evolutionarily conserved splicing activator Tra2β (Sfrs10 is essential for mouse embryogenesis and implicated in spermatogenesis. Here we find that Tra2β is up-regulated as the mitotic stem cell containing population of male germ cells differentiate into meiotic and post-meiotic cells. Using CLIP coupled to deep sequencing, we found that Tra2β binds a high frequency of exons and identified specific G/A rich motifs as frequent targets. Significantly, for the first time we have analysed the splicing effect of Sfrs10 depletion in vivo by generating a conditional neuronal-specific Sfrs10 knock-out mouse (Sfrs10(fl/fl; Nestin-Cre(tg/+. This mouse has defects in brain development and allowed correlation of genuine physiologically Tra2β regulated exons. These belonged to a novel class which were longer than average size and importantly needed multiple cooperative Tra2β binding sites for efficient splicing activation, thus explaining the observed splicing defects in the knockout mice. Regulated exons included a cassette exon which produces a meiotic isoform of the Nasp histone chaperone that helps monitor DNA double-strand breaks. We also found a previously uncharacterised poison exon identifying a new pathway of feedback control between vertebrate Tra2 proteins. Both Nasp-T and the Tra2a poison exon are evolutionarily conserved, suggesting they might control fundamental developmental processes. Tra2β protein isoforms lacking the RRM were able to activate specific target exons indicating an additional functional role as a splicing co-activator. Significantly the N-terminal RS1 domain conserved between flies and humans was essential for the splicing activator function of Tra2β. Versions of Tra2β lacking this N-terminal RS1 domain potently repressed the same target exons activated by full-length Tra2β protein.

2017-01-01

Based on the current SyncTraX that was developed jointly with Hokkaido University, we have developed the SyncTraX FX4 version, which features not only tumor tracking but also patient positioning. The SyncTraX FX4 version is configured with four fixed x-ray tubes an detectors and eliminated the rail that is used to move the x-ray tube and detector as in the current SyncTraX. This development simplifies limitations on facility construction. We also adopted a distortion free flat panel detector instead of a color I.I., and the additional patient positioning feature will enable the SyncTraX FX4 version to become more widely applied in clinical cases.

On the dominant noise components of tactical aircraft: Laboratory to full scale

Science.gov (United States)

Tam, Christopher K. W.; Aubert, Allan C.; Spyropoulos, John T.; Powers, Russell W.

2018-05-01

This paper investigates the dominant noise components of a full-scale high performance tactical aircraft. The present study uses acoustic measurements of the exhaust jet from a single General Electric F414-400 turbofan engine installed in a Boeing F/A-18E Super Hornet aircraft operating from flight idle to maximum afterburner. The full-scale measurements are to the ANSI S12.75-2012 standard employing about 200 microphones. By comparing measured noise spectra with those from hot supersonic jets observed in the laboratory, the dominant noise components specific to the F/A-18E aircraft at different operating power levels are identified. At intermediate power, it is found that the dominant noise components of an F/A-18E aircraft are essentially the same as those of high temperature supersonic laboratory jets. However, at military and afterburner powers, there are new dominant noise components. Their characteristics are then documented and analyzed. This is followed by an investigation of their origin and noise generation mechanisms.

Spencer, V. K.; Solie, D. J.

2010-12-01

Bush Physics for the 21st Century (BP21) is a distance education physics course offered through the Interior Aleutians Campus of the University of Alaska Fairbanks. It provides an opportunity for rural Alaskan high school and community college students, many of whom have no other access to advanced science courses, to earn university science credit. The curriculum is mathematically rigorous and includes a laboratory component to prepare students who wish to pursue science and technology careers. The laboratory component has been developed during the past 3 years. Students learn lab safety, basic laboratory technique, experiment components and group collaboration. Experiments have place-based themes and involve skills that translate to rural Alaska when possible. Preliminary data on the general effectiveness of the labs have been analyzed and used to improve the course.

Gajewski, K G; Chen, Y-T; Hsieh, Y-H P

2009-04-01

Four IgG (subclass IgG1) class monoclonal antibodies (MAbs) strongly reactive to Asian farm-raised Pangasius catfish, tra (Pangasius hypophthalmus) and basa (Pangasius bocourti), have been developed. These MAbs were raised by immunizing an animal with thermal-stable crude sarcoplasmic protein extract of cooked tra. The MAbs were selected by screening hybridoma clones against more than 70 common fish and meat protein extracts. Two MAbs, T7E10 and T1G11, were found to be specific to the Asian Pangasius catfish, tra, and basa, with no cross-reactions with any of the common fish and meat species or with the food additive proteins (bovine serum albumin, soy proteins, milk proteins, egg proteins, and gelatin) tested. MAb T7E10 recognized 2 antigenic proteins (molecular weight approximately 36 and 75 kDa) in raw and cooked tra and basa extracts, while T1G11 bound to several proteins (molecular weight between 13 and 18 kDa) in tra and basa extracts. Two other MAbs, F7B8 and F1G11, recognized a common protein (36 KDa) and cross-reacted with all the fish extracts tested and with several mammalian species. These MAbs can be employed individually or in combination in various formats of immunoassays for rapid identification of Pangasius catfish, either raw or cooked. They can also be used to study the biological, biochemical, and physiological aspects of thermal-stable antigenic proteins. This is the first study identifying these thermal-stable antigenic proteins present in Pangasius catfish as species-specific biomarkers.

Walter, Frederick M.; Burwitz, Vadim; Kafka, Stella

2018-06-01

The classical nova NR TrA was discovered as an O-type optically-thick classical nova. There is no evidence that it formed dust. Within four years the envelope became sufficiently thin to reveal an eclipsing accretion disk-dominated system with orbitally-modulated permitted lines of C IV, N V, and O VI. XMM observations reveal a non-eclipsing soft X-ray source and a deeply-eclipsing UV continuum. We will present the first ten years of optical spectral evolution of this system accompanied by ten years of BVRIJHK photometry, with an eye to deciphering the current nature of the system.

Background: Transradial coronary angiography (TRA) has been associated with increased radiation doses. We hypothesized that contemporary image noise reduction technology would reduce radiation doses in the cardiac catheterization laboratory in a typical clinical setting. Methods and results: We performed a single-center, retrospective analysis of 400 consecutive patients who underwent diagnostic and interventional cardiac catheterizations in a predominantly TRA laboratory with traditional fluoroscopy (N = 200) and a new image noise reduction fluoroscopy system (N = 200). The primary endpoint was radiation dose (mGy cm{sup 2}). Secondary endpoints were contrast dose, fluoroscopy times, number of cineangiograms, and radiation dose by operator between the two study periods. Radiation was reduced by 44.7% between the old and new cardiac catheterization laboratory (75.8 mGy cm{sup 2} ± 74.0 vs. 41.9 mGy cm{sup 2} ± 40.7, p < 0.0001). Radiation was reduced for both diagnostic procedures (45.9%, p < 0.0001) and interventional procedures (37.7%, p < 0.0001). There was no statistically significant difference in radiation dose between individual operators (p = 0.84). In multivariate analysis, radiation dose remained significantly decreased with the use of the new system (p < 0.0001) and was associated with weight (p < 0.0001), previous coronary artery bypass grafting (p < 0.0007) and greater than 3 stents used (p < 0.0004). TRA was used in 90% of all cases in both periods. Compared with a transfemoral approach (TFA), TRA was not associated with higher radiation doses (p = 0.20). Conclusions: Image noise reduction technology significantly reduces radiation dose in a contemporary radial-first cardiac catheterization clinical practice. - Highlights: • Radial arterial access has been associated with higher doses compared to femoral access. • In a radial-first cardiac catheterization laboratory (90% radial) we examined radiation doses reduction with a contemporary image

Background: Transradial coronary angiography (TRA) has been associated with increased radiation doses. We hypothesized that contemporary image noise reduction technology would reduce radiation doses in the cardiac catheterization laboratory in a typical clinical setting. Methods and results: We performed a single-center, retrospective analysis of 400 consecutive patients who underwent diagnostic and interventional cardiac catheterizations in a predominantly TRA laboratory with traditional fluoroscopy (N = 200) and a new image noise reduction fluoroscopy system (N = 200). The primary endpoint was radiation dose (mGy cm"2). Secondary endpoints were contrast dose, fluoroscopy times, number of cineangiograms, and radiation dose by operator between the two study periods. Radiation was reduced by 44.7% between the old and new cardiac catheterization laboratory (75.8 mGy cm"2 ± 74.0 vs. 41.9 mGy cm"2 ± 40.7, p < 0.0001). Radiation was reduced for both diagnostic procedures (45.9%, p < 0.0001) and interventional procedures (37.7%, p < 0.0001). There was no statistically significant difference in radiation dose between individual operators (p = 0.84). In multivariate analysis, radiation dose remained significantly decreased with the use of the new system (p < 0.0001) and was associated with weight (p < 0.0001), previous coronary artery bypass grafting (p < 0.0007) and greater than 3 stents used (p < 0.0004). TRA was used in 90% of all cases in both periods. Compared with a transfemoral approach (TFA), TRA was not associated with higher radiation doses (p = 0.20). Conclusions: Image noise reduction technology significantly reduces radiation dose in a contemporary radial-first cardiac catheterization clinical practice. - Highlights: • Radial arterial access has been associated with higher doses compared to femoral access. • In a radial-first cardiac catheterization laboratory (90% radial) we examined radiation doses reduction with a contemporary image-noise compared to

The role of genetic variations within the ghrelin gene on cardiometabolic profile and nutritional status is still not clear in humans, particularly in elderly people. We investigated six SNPs of the ghrelin gene and their relationship with metabolic syndrome (MS) components. 824 subjects (413 men/411 women, age 77.31±5.04) participating in the Mataró aging study (n = 310) and the Hortega study (n = 514) were analyzed. Anthropometric variables, ghrelin, lipids, glucose and blood pressure levels were measured, and distribution of SNPs -994CT (rs26312), -604GA (rs27647), -501AC (rs26802), R51Q (rs34911341), M72L (rs696217) and L90G (rs4684677) of the ghrelin gene evaluated. Genotypes were determined by multiplex PCR and SNaPshot minisequencing. MS (IDF criteria) was found in 54.9%. No association between any of the SNPs and levels of total fasting circulating ghrelin levels was found. C/A-A/A genotype of M72L was associated with increased risk of central obesity according to IDF criteria, while G/A-G/G genotypes of -604GA with reduced risk. A/A genotype of -501AC polymorphism was associated to decreased BMI. In relation to lipid profile, the same genotypes of -604GA were associated with increased total cholesterol and LDL-cholesterol and -501AC with reduced triglycerides. There were no associations with systolic or diastolic blood pressure levels or with hypertension, glucose levels or diabetes and ghrelin polymorphisms. However, G/G genotype of -604GA was associated with glucose >100 mg/dL. Haplotype analysis showed that only one haplotype is associated with increased risk of waist circumference and central obesity. The analysis of subjects by gender showed an important and different association of these polymorphisms regarding MS parameters. Ghrelin gene variants -604GA, -501AC and M72L are associated with certain components of MS, in particular to BMI and lipid profile in elderly Spanish subjects.

We present a near-infrared study focused on the detection and characterization of the youngest stellar component of the NGC 604 giant star-forming region in the Triangulum galaxy (M 33). By means of color-color diagrams derived from the photometry of JHK{sub s} images taken with the Gemini Near Infrared Imaging and Spectrometer (NIRI), we have found 68 candidate massive young stellar objects. The spatial distribution of these sources matches the areas where previous studies suggested that star formation might be taking place, and the high spatial resolution of our deep NIRI imaging allows us to pinpoint the star-forming knots. An analysis of the fraction of objects that show infrared excess suggests that the star formation is still active, supporting the presence of a second generation of stars being born, although the evidence for or against sequential star formation does not seem to be conclusive.

Niva, G.D.; Schmidt, E.G.

1981-01-01

It was suggested that U TrA was a Cepheid with a modulated light curve. Further photometric and radial-velocity observations have confirmed this behaviour. Unfortunately, the radial velocities are too few in number and too scattered to allow a detailed analysis. This paper presents further photometric and spectroscopic observations of U TrA. The original intent was to obtain enough simultaneous observations to perform a Wesselink analysis similar to the one made for another beat Cepheid, TU Cas. Unfortunately, this has not been possible. However, the data obtained are of high quality and are clearly useful in studies of the modal content and period stability of the star. (author)

Reungoat, Patrice; Chiron, Mireille; Gauvin, Stephanie; Le Moullec, Y.; Momas, Isabelle

2003-01-01

The ExTra index, produced by the French Scientific Center for Building Physics, evaluates ambient concentrations of transport-related pollutants in front of the work and living places of urban dwellers. This study contributes to the validation of the ExTra index by carrying out measurements in four French cities. It compares nitrogen oxide concentrations (NO x ) measured over 6 weeks with passive samplers, and NO x calculated concentrations using the ExTra index. The study takes into account traffic density, topographical parameters (building height, road, and pavement width), weather conditions (wind direction and strength), and background pollution levels. The model was tested at 100 street canyons sites. There were highly significant correlations (0.90 in Grenoble, 0.95 in Nice, 0.89 in Paris, and 0.89 in Toulouse) and good intraclass correlation coefficients (0.75 in Grenoble, 0.91 in Nice, 0.89 in Paris, and 0.86 in Toulouse) between the two series of values. These results suggest that if the ExTra index were to be applied to all the different residences and workplaces of a subject throughout his (her) life, it could be a useful epidemiological tool for studying the long-term health effects of transport-related emissions and for reconstructing individual exposure to such pollution in order to avoid misclassification

Full Text Available A pesquisa de campo sobre produção da subjetividade enfrenta o problema de construir conhecimento envolvendo pesquisadores e pesquisados, com territórios e semióticas singulares. Surgem questões relativas ao protagonismo dos participantes e a como traçar com eles um plano comum, garantindo o caráter participativo da pesquisa. No contexto do método da cartografia, o artigo tem como objetivo tratar do tema do comum num duplo aspecto. Num primeiro, discute o acesso ao plano comum. Com base em Gilles Deleuze e Felix Guattari, tal plano não é dito homogêneo nem reúne atores que manteriam entre si relações de identidade, mas opera comunicação entre singularidades, sendo pré-individual e coletivo. Num segundo aspecto, aponta que, enquanto pesquisa-intervenção, a cartografia se compromete com a criação de um mundo comum e heterogêneo. O artigo mostra que o traçado do comum tem como diretriz metodológica a tranversalidade e examina os procedimentos de participação, inclusão e tradução.

Bleaching treatments can affect release of components from conventional composites. In this continuing study the influence of two different bleaching gels on the elution of bulk-fill composite components was investigated. The composites Tetric EvoCeram(®) Bulk Fill, QuiXFil™ and X-tra fil were treated with the bleaching gels Opalescence PF 15% (PF 15%) for 5 h and PF 35% (PF 35%) for 30 min and then stored in methanol and water for 24 h and 7 d. The eluates were analyzed by gas chromatography/mass spectrometry (GC/MS). Unbleached specimens were used as control group. A total of 7 different elutable substances have been identified from the investigated composites after bleaching-treatment. Three of them were methacrylates: 2-hydroxyethyl methacrylate (HEMA), triethylene glycol dimethacrylate (TEGDMA) and trimethylolpropane trimethacrylate (TMPTMA). Compared to the unbleached controls an increase in elution after PF 15%-treatment of following compounds was found: HEMA (Tetric EvoCeram(®) Bulk Fill), TEGDMA (QuiXFil™, X-tra fil) and 4-N,N-dimethylaminobenzoic acid butyl ethoxy ester (DMABEE) (Tetric EvoCeram(®) Bulk Fill, QuiXFil™, X-tra fil). Following compounds showed a reduction in elution after PF 35%-treatment compared to controls: TEGDMA (QuiXFil™) and DMABEE (Tetric EvoCeram(®) Bulk Fill). The highest concentration of HEMA was 0.22 mmol/l (Tetric EvoCeram(®) Bulk Fill, methanol, 7 d, PF 15%), the highest concentration of TEGDMA was 0.3 mmol/l (X-tra fil, water, 7 d, PF 15%) and the highest concentration of DMABEE was 0.05 mmol/l (QuiXFil™, water, 7 d, PF 35%). PF 15% and PF 35% can lead to reduced and/or increased elution of some bulk-fill components, compared to unbleached bulk-fill composites. Copyright © 2015 Academy of Dental Materials.

Total error components - isolation of laboratory variation from method performance

International Nuclear Information System (INIS)

Bottrell, D.; Bleyler, R.; Fisk, J.; Hiatt, M.

1992-01-01

The consideration of total error across sampling and analytical components of environmental measurements is relatively recent. The U.S. Environmental Protection Agency (EPA), through the Contract Laboratory Program (CLP), provides complete analyses and documented reports on approximately 70,000 samples per year. The quality assurance (QA) functions of the CLP procedures provide an ideal data base-CLP Automated Results Data Base (CARD)-to evaluate program performance relative to quality control (QC) criteria and to evaluate the analysis of blind samples. Repetitive analyses of blind samples within each participating laboratory provide a mechanism to separate laboratory and method performance. Isolation of error sources is necessary to identify effective options to establish performance expectations, and to improve procedures. In addition, optimized method performance is necessary to identify significant effects that result from the selection among alternative procedures in the data collection process (e.g., sampling device, storage container, mode of sample transit, etc.). This information is necessary to evaluate data quality; to understand overall quality; and to provide appropriate, cost-effective information required to support a specific decision

Full Text Available Background & Objective: Divorce, unwanted pregnancies, and unsuccessful marriages create mental, emotional, physical, and financial problems for individuals, families, and ultimately the community. Premarital education and counseling is one of the most effective ways for the prevention of such problems. The purpose of this study was to describe and evaluate the effectiveness of a premarital educational program by using the TRA (Theory of Reasoned Action. Materials and Methods: Four hundred couples who attended premarital education and counseling classes voluntarily participated in this descriptive and analytical study. Variables such as attitude, subjective norms, and intention, were collected by using a validated questionnaire based on the TRA components. The questionnaire was filled out before and after the educational classes. Results: The mean age of the couples was 23.16 ± 5.64 years old. Statistically significant differences were found in knowledge, attitude, and subjective norms before and after participation in the classes (p value 0.05. Conclusion: Although the mean knowledge and attitude of the couples under study increased after the classes, the increase was not high and only 20% of the couples gained acceptable knowledge. The effectiveness of such classes in the current manner is very low. Application of appropriate educational methods and media-based models and theories is highly recommended.

The computerised Mayfair Accountancy System (MYDAS) has been developed to account for irradiated components in the Mayfair Laboratory at Culcheth and supersedes a card-index system. The computerised system greatly improves the availability of the data held and it ensures, by means of extensive data validation programs, that the data accurately represent the current inventory of irradiated components in the Laboratory. The system has been implemented on the Risley ICL 2966 main-frame computer and uses an IDMS database to store the data. The computer is accessed through the facilities of the Transaction Processing Management System (TPMS) providing rapid and secure access to the database from several visual display units and printers simultaneously.

La portata etica della tragedia tra Bernard Williams e Martha Nussbaum

Directory of Open Access Journals (Sweden)

Francesco Testini

2015-11-01

Full Text Available Questo breve scritto si propone di ripercorrere sinteticamente alcuni nodi fondamentali del dibattito filosofico tra Bernard Williams e Martha Nussbaum sul significato e sul valore etico della rappresentazione tragica non tanto all’interno del mondo greco quanto per la contemporaneità. Il campo su cui questa analisi intende muoversi è delimitato principalmente da due testi fondamentali come Vergogna e Necessità e l’introduzione alla nuova edizione del 2001, insieme alla prima parte, de La fragilità del bene. Si cercherà di mostrare lo scarto tra queste due diverse concezioni riconducendo ad ognuna il particolare atteggiamento etico che sostiene; di questi diversi punti di vista si cercherà di ricostruire il nesso con le differenti interpretazioni che i due autori forniscono dell’Agamennone di Eschilo e con le diverse reazioni che motivano nei confronti del protagonista e della sua vicenda. Gli obiettivi delle argomentazioni che seguono sono principalmente due: innanzitutto evidenziare come in alcune delle critiche mosse dalla filosofa americana al collega britannico siano rinvenibili spunti fondamentali per quella che si ritiene una più completa comprensione della tragedia come caso limite del conflitto tra soggetto etico e mondo e, in secondo luogo, produrre una giustificazione filosofica ulteriore della reazione motivata da Nussbaum davanti alla condotta di Agamennone che sia compatibile con l’approccio di Williams attraverso una riproposizione del conflitto di valori in termini di conflitto di ruoli.

A new component of the Nasonia sex determining cascade is maternally silenced and regulates transformer expression.

Although sex determination is a universal process in sexually reproducing organisms, sex determination pathways are among the most highly variable genetic systems found in nature. Nevertheless, general principles can be identified among the diversity, like the central role of transformer (tra) in insects. When a functional TRA protein is produced in early embryogenesis, the female sex determining route is activated, while prevention of TRA production leads to male development. In dipterans, male development is achieved by prevention of female-specific splicing of tra mRNA, either mediated by X-chromosome dose or masculinizing factors. In Hymenoptera, which have haplodiploid sex determination, complementary sex determination and maternal imprinting have been identified to regulate timely TRA production. In the parasitoid Nasonia, zygotic transformer (Nvtra) expression and splicing is regulated by a combination of maternal provision of Nvtra mRNA and silencing of Nvtra expression in unfertilized eggs. It is unclear, however, if this silencing is directly on the tra locus or whether it is mediated through maternal silencing of a trans-acting factor. Here we show that in Nasonia, female sex determination is dependent on zygotic activation of Nvtra expression by an as yet unknown factor. This factor, which we propose to term womanizer (wom), is maternally silenced during oogenesis to ensure male development in unfertilized eggs. This finding implicates the upstream recruitment of a novel gene in the Nasonia sex determining cascade and supports the notion that sex determining cascades can rapidly change by adding new components on top of existing regulators.

ART, Stoffenmanager, and TRA: A Systematic Comparison of Exposure Estimates Using the TREXMO Translation System.

Science.gov (United States)

Savic, Nenad; Gasic, Bojan; Vernez, David

2017-12-15

Several occupational exposure models are recommended under the EU's REACH legislation. Due to limited availability of high-quality exposure data, their validation is an ongoing process. It was shown, however, that different models may calculate significantly different estimates and thus lead to potentially dangerous conclusions about chemical risk. In this paper, the between-model translation rules defined in TREXMO were used to generate 319000 different in silico exposure situations in ART, Stoffenmanager, and ECETOC TRA v3. The three models' estimates were computed and the correlation and consistency between them were investigated. The best correlated pair was Stoffenmanager-ART (R, 0.52-0.90), whereas the ART-TRA and Stoffenmanager-TRA correlations were either lower (R, 0.36-0.69) or no correlation was found. Consistency varied significantly according to different exposure types (e.g. vapour versus dust) or settings (near-field versus far-field and indoors versus outdoors). The percentages of generated situations for which estimates differed by more than a factor of 100 ranged from 14 to 97%, 37 to 99%, and 1 to 68% for Stoffenmanager-ART, TRA-ART, and TRA-Stoffenmanager, respectively. Overall, the models were more consistent for vapours than for dusts and solids, near-fields than for far-fields, and indoor than for outdoor exposure. Multiple linear regression analyses evidenced the relationship between the models' parameters and the relative differences between the models' predictions. The relative difference can be used to estimate the consistency between the models. Furthermore, the study showed that the tiered approach is not generally applicable to all exposure situations. These findings emphasize the need for a multiple-model approach to assessing critical exposure scenarios under REACH. Moreover, in combination with occupational exposure measurements, they might also be used for future studies to improve prediction accuracy. © The Author(s) 2017

Several tests are available to optometrists for investigating accommodation and vergence. This study sought to investigate the agreement between clinical and laboratory methods and to clarify which components are actually measured when tonic and cross-link of accommodation and vergence are assessed. Tonic vergence, tonic accommodation, accommodative vergence (AC/A) and vergence accommodation (CA/C) were measured using several tests. Clinical tests were compared to the laboratory assessment, the latter being regarded as an absolute reference. The repeatability of each test and the degree of agreement between the tests were quantified using Bland-Altman analysis. The values obtained for each test were found to be stable across repetitions; however, in most cases, significant differences were observed between tests supposed to measure the same oculomotor component. Tonic and cross-link components cannot be easily assessed because proximal and instrumental responses interfere with the assessment. Other components interfere with oculomotor assessment. Specifically, accommodative divergence interferes with tonic vergence estimation and the type of accommodation considered in the AC/A ratio affects its magnitude. Results on clinical tonic accommodation and clinical CA/C show that further investigation is needed to clarify the limitations associated with the use of difference of Gaussian as visual targets to open the accommodative loop. Although different optometric tests of accommodation and vergence rely on the same basic principles, the results of this study indicate that clinical and laboratory methods actually involve distinct components. These differences, which are induced by methodological choices, must be taken into account, when comparing studies or when selecting a test to investigate a particular oculomotor component. © 2015 The Authors.

OSSERVAZIONI SU UNO SCAMBIO DI POEMETTI TRA PIETRO STANCOVICH E MARTINO FIORANTI

Full Text Available Il lavoro presenta un’analisi comparata tra due poemetti d’occasione in dialetto istroveneto dell’Istria sud-occidentale. I componimenti, scritti nel 1826 dal dignanese Martino Fioranti e dal canonico di Barbana Pietro Stancovich, rappresentano un’importante attestazione della presenza di un’attività poetica in quella che rappresentava all’epoca la koiné del territorio istriano, cioè l’idioma di diretta derivazione veneziana. I poemetti rivestono scarsa importanza a livello letterario. Più interessanti si rivelano, invece, se osservati da una prospettiva storica e documentaristica, attraverso la quale ci si svela l’ambiente, il costume dell’epoca, e soprattutto il rapporto di cordiale amicizia che univa i due poeti. In chiusura del lavoro si dà un breve confronto tra il poemetto e i tre sonetti di Martino Fioranti, rinvenuti nell’archivio della Biblioteca universitaria di Pola.

Full Text Available Come rispondono le politiche di conciliazione cura-lavoro alle esigenze delle lavoratrici e dei lavoratori di nuova generazione: sempre più precari, poveri e instabili dal punto di vista reddituale e/o professionale? Con un sostanziale immobilismo politico.  Questo è il quadro che viene fuori da una rassegna delle principali politiche sociali italiane volte a supporto della genitorialità e alla garanzia dell’occupazione femminile. Il contributo mette in luce i limiti di tali politiche e coglie gli aspetti innovativi di pratiche che si sviluppano dal basso.  Al contempo, una riflessione al margine lascia aperta una importante questione sul rapporto tra flessibilità e conciliazione, ovvero tra organizzazione del lavoro e tempi di cura per la famiglia. Nell’era della rivoluzione digitale,  individuamo forti resistenze al cambiamento, sia da parte delle istituzioni, ma anche e soprattutto dal mondo produttivo, che vanta si modelli “agili” di forme di lavoro da un punto di vista formale (vedi il lavoro agile/ smart working ma che dal punto di vista sostanziale rimane radicato a modelli di contrattazione standar che non agevola né la condizioine lavorativa da un punto di vista di tutele né la conciliaizone cura lavoro e quindi l’occupazione femminile.

Candidate Essential Genes in Burkholderia cenocepacia J2315 Identified by Genome-Wide TraDIS

2016-08-22

Burkholderia cenocepacia infection often leads to fatal cepacia syndrome in cystic fibrosis patients. However, antibiotic therapy rarely results in complete eradication of the pathogen due to its intrinsic resistance to many clinically available antibiotics. Recent attention has turned to the identification of essential genes as the proteins encoded by these genes may serve as potential targets for development of novel antimicrobials. In this study, we utilized TraDIS (Transposon Directed Insertion-site Sequencing) as a genome-wide screening tool to facilitate the identification of B. cenocepacia genes essential for its growth and viability. A transposon mutant pool consisting of approximately 500,000 mutants was successfully constructed, with more than 400,000 unique transposon insertion sites identified by computational analysis of TraDIS datasets. The saturated library allowed for the identification of 383 genes that were predicted to be essential in B. cenocepacia. We extended the application of TraDIS to identify conditionally essential genes required for in vitro growth and revealed an additional repertoire of 439 genes to be crucial for B. cenocepacia growth under nutrient-depleted conditions. The library of B. cenocepacia mutants can subsequently be subjected to various biologically related conditions to facilitate the discovery of genes involved in niche adaptation as well as pathogenicity and virulence.

Vestite alla turchesca. Travestimenti orientali nella drammaturgia italiana e francese tra Sei e Settecento

Stefano Agostino Moretti

2011-11-01

Full Text Available Da secoli il Mar Mediterraneo rappresenta un confine tra due mondi. Gli orientalisti li chiamavano e continuano a chiamarli mondo “arabo” e mondo “cristiano”. Questo contributo vuole mostrare come, in tempi non sospetti, l’Italia rappresentasse un ponte tra queste due culture. Grazie agli strumenti della storiografia contemporanea, attenta alla vita quotidiana e agli “archivi del corpo”, scopriamo che durante il XVI e il XVII secolo gli incontri tra musulmani e cristiani fossero molto frequenti e spesso felici. Il teatro comico italiano fu il genere letterario che, prima e meglio di ogni altro, riuscì a cogliere e a descrivere tale fenomeno con tutte le implicazioni politiche, religiose e identitarie, restituendone in pieno uno degli elementi sovente sottaciuti e censurati, ovvero la perturbante carica erotica del “diverso”. Uno degli espedienti che riassumono con maggiore efficacia questo  rapporto identitario e culturale è rappresentato dall’uso del travestimento. Paragonando alcune commedie italiane della prima metà del Seicento con il teatro “orientalista” di Bonarelli, Molière e Goldoni, possiamo osservare la nascita e la crescita di una visione stereotipata e libresca dell’altro, là dove i “panni turcheschi” generavano negli spettatori paura e desiderio.

Full Text Available This paper reconsiders some important episodes of the history of drama and theater of the imagination spread between Naples and Madrid or more generally between Italy and Spain with reference to the Tarasca (procession of Corpus Domini, ideally through six ‘stations’. In this Spanish procession we find on a female dragon the effigies of Gennaro and Gaetano Sacchi, uncle and father of the more famous Antonio, whose stories and travels are one of the matters of this paper. The other matters are focused on the relationship between Carlo Goldoni and the Neapolitans Domenico Barone and Domenico Lalli, and on the Venetian reinvention of Pulcinella’s mask by Giandomenico Tiepolo, passing through Madrid.Col riferimento a una processione legata prevalentemente al Corpus Domini, attraverso sei ‘stazioni’ ideali, il contributo riconsidera alcuni rilevanti episodi di storia dello spettacolo e di diffusione dell’immaginazione teatrale tra Napoli e Madrid, o più in generale tra l’Italia e la Spagna. Nella processione madrilena – sopra un drago femmina semovente (la Tarasca, appunto – si ritrovano le effigi di Gennaro e Gaetano Sacchi, zio e padre del più celebre Antonio, le cui vicende e le cui peregrinazioni costituiscono il filo principale del racconto; gli altri sono costituiti dai rapporti di Carlo Goldoni coi napoletani Domenico Barone e Domenico Lalli e dalla reinvenzione veneziana – passando per Madrid – della maschera di Pulcinella da parte di Giandomenico Tiepolo.

2015-05-01

Full Text Available The literature on scientific-Indigenous ecological knowledge collaborations rarely analyses programmatic efforts undertaken by multi-disciplinary research groups over very large geographic scales. The TRaCK (Tropical Rivers and Coastal Knowledge research program was established to provide the science and knowledge needed by governments, industries, and communities to sustainably manage northern Australia’s rivers and estuaries. A number of policies and procedures were developed to ensure that the needs of Indigenous people of the multi-jurisdictional region were addressed and to enhance the benefits they might derive from participating in the research. An overarching Indigenous Engagement Strategy undergirded the program’s engagement activities, providing guidance on matters relating to the protection of intellectual property, negotiation of research agreements, remuneration for Indigenous expertise, and communications standards. This article reviews the achievements and shortcomings of the TRaCK experience of Indigenous engagement and highlights lessons for researchers and research organisations contemplating applied environmental science initiatives of this scale and scope.

Valeev, B. U.; Pisarev, V. V.

2018-01-01

In this work, we study the vapor-liquid equilibrium in n-pentane. We use the TraPPE-EH (transferable potentials for phase equilibria-explicit hydrogen) forcefield, where each hydrogen and carbon atom is considered as independent center of force. The fluid behavior was investigated with different values of density and temperature by molecular dynamics method. The n-pentane evaporation curve was calculated in the temperature range of 290 to 390 K. The densities of the coexisting phases are also calculated. The compression curve at 370 K was calculated and isothermal bulk modulus was found. The simulated properties of n-pentane are in good agreement with data from a database of the National Institute of Standards and Technology, so the TraPPE-EH model can be recommended for simulations of hydrocarbons.

Cleaning and Decontamination Using Strippable and Protective Coatings at the Idaho National Engineering and Environmental Laboratory

International Nuclear Information System (INIS)

Tripp, J.; Archibald, K.; Lauerhass, L.; Argyle, M.; Demmer, R.

1999-01-01

The Idaho National Engineering and Environmental Laboratory (INEEL) Radioactive Liquid Waste Reduction (RLWR) group is conducting a testing and evaluation program on strippable and protective coatings. The purpose of the program is to determine how and where these coatings can be used to aid in the minimization of liquid waste generation. These coatings have become more important in daily operations because of the increased concern of secondary liquid waste generation at the INEEL. Several different strippable and protective coatings were investigated by the RLWR group, including Pentek 604, Bartlett (TLC), and ALARA 1146. During the tests quantitative data was determined, such as effectiveness at reducing contamination levels, or costs, as well as some qualitative data on issues like ease of application or removal. PENTEK 604 and Bartlett TLC are seen as superior products with slightly different uses

2000-12-01

The InTraCert project aims to explore the possibility of integrating the existing and planned Tradable Green Certificate (TGC) schemes in the European Union and, therefore, creating a plausible unified market for TGCs. Particular attention will be paid to the possibilities of integrating TGCs for green electricity, heat and gas. Furthermore, it intents to examine the possible interactions arising from such a system with more direct GHG abatement measures, i.e. Carbon Emissions Trading (CET). The scope of the InTraCert project requires specific information for EU-15 countries regarding, on the one hand, Renewable Energy Sources (RES) used for electricity, gas and heat generation and. on the other, GHG emission levels and national strategies. In order to account for this information need. specific country inventories have been designed and carried out by InTraCert members in this first phase of the project. The inventory shows that Belgium, Italy, Denmark, the Netherlands, Austria, Sweden and the UK seriously want to implement a TGC system. The systems will indeed be nationally oriented; hardly any provisions for international trade in the different TGCs will be put in place. An essential prerequisite for efficient cross border trade is agreement on the carbon credit that comes with RE production. What is the size of the carbon credit and will this credit be attached to the TGC while traded? These will be the main questions to be answered in the next phase of the InTraCert project. 8 refs

First tier modeling of consumer dermal exposure to substances in consumer articles under REACH: a quantitative evaluation of the ECETOC TRA for consumers tool.

Science.gov (United States)

Delmaar, J E; Bokkers, B G H; ter Burg, W; van Engelen, J G M

2013-02-01

The demonstration of safe use of chemicals in consumer products, as required under REACH, is proposed to follow a tiered process. In the first tier, simple conservative methods and assumptions should be made to quickly verify whether risks for a particular use are expected. The ECETOC TRA Consumer Exposure Tool was developed to assist in first tier risk assessments for substances in consumer products. The ECETOC TRA is not a prioritization tool, but is meant as a first screening. Therefore, the exposure assessment needs to cover all products/articles in a specific category. For the assessment of the dermal exposure for substances in articles, ECETOC TRA uses the concept of a 'contact layer', a hypothetical layer that limits the exposure to a substance contained in the product. For each product/article category, ECETOC TRA proposes default values for the thickness of this contact layer. As relevant experimental exposure data is currently lacking, default values are based on expert judgment alone. In this paper it is verified whether this concept meets the requirement of being a conservative exposure evaluation method. This is done by confronting the ECETOC TRA expert judgment based predictions with a mechanistic emission model, based on the well established theory of diffusion of substances in materials. Diffusion models have been applied and tested in many applications of emission modeling. Experimentally determined input data for a number of material and substance combinations are available. The estimated emissions provide information on the range of emissions that could occur in reality. First tier tools such as ECETOC TRA tool are required to cover all products/articles in a category and to provide estimates that are at least as high as is expected on the basis of current scientific knowledge. Since this was not the case, it is concluded that the ECETOC TRA does not provide a proper conservative estimation method for the dermal exposure to articles. An

pTRA - A reporter system for monitoring the intracellular dynamics of gene expression.

Science.gov (United States)

Wagner, Sabine G; Ziegler, Martin; Löwe, Hannes; Kremling, Andreas; Pflüger-Grau, Katharina

2018-01-01

The presence of standardised tools and methods to measure and represent accurately biological parts and functions is a prerequisite for successful metabolic engineering and crucial to understand and predict the behaviour of synthetic genetic circuits. Many synthetic gene networks are based on transcriptional circuits, thus information on transcriptional and translational activity is important for understanding and fine-tuning the synthetic function. To this end, we have developed a toolkit to analyse systematically the transcriptional and translational activity of a specific synthetic part in vivo. It is based on the plasmid pTRA and allows the assignment of specific transcriptional and translational outputs to the gene(s) of interest (GOI) and to compare different genetic setups. By this, the optimal combination of transcriptional strength and translational activity can be identified. The design is tested in a case study using the gene encoding the fluorescent mCherry protein as GOI. We show the intracellular dynamics of mRNA and protein formation and discuss the potential and shortcomings of the pTRA plasmid.

Risk-Based Disposal Plan for PCB Paint in the TRA Fluorinel Dissolution Process Mockup and Gamma Facilities Canal

2008-05-01

This Toxic Substances Control Act Risk-Based Polychlorinated Biphenyl Disposal plan was developed for the Test Reactor Area Fluorinel Dissolution Process Mockup and Gamma Facilities Waste System, located in Building TRA-641 at the Reactor Technology Complex, Idaho National Laboratory Site, to address painted surfaces in the empty canal under 40 CFR 761.62(c) for paint, and under 40 CFR 761.61(c) for PCBs that may have penetrated into the concrete. The canal walls and floor will be painted with two coats of contrasting non-PCB paint and labeled as PCB. The canal is covered with open decking; the access grate is locked shut and signed to indicate PCB contamination in the canal. Access to the canal will require facility manager permission. Protective equipment for personnel and equipment entering the canal will be required. Waste from the canal, generated during ultimate Decontamination and Decommissioning, shall be managed and disposed as PCB Bulk Product Waste.

Laboratory tests of three Z‐Land Fairfield Nodal 5‐Hz, three‐component sensors

Science.gov (United States)

Ringler, Adam; Anthony, Robert E.; Karplus, M.S; Holland, Austin; Wilson, David

2018-01-01

We conduct a number of laboratory tests at the Albuquerque Seismological Laboratory to verify the self‐noise and fidelity in which 3 three‐component Fairfield Nodal Z‐Land, Generation 2, 5‐Hz sensors are able to record seismic signals. In addition to the incoherent self‐noise of the sensors, we estimate the sensitivity of the units in digital volts/m/s, the damping, and the free period. These three parameters allow us to completely characterize the response of the instruments. We find that the responses of all components match a mean‐derived response to within 5% of amplitude and 0.03 radians in phase. This close agreement suggests that for most applications a nominal response is suitable. We also checked the timing of the units as compared to a Quanterra Q330HR and found good agreement up to 200samples/s . Finally, we compared the results of our noise tests on these sensors to a couple of nodal sensors recently deployed at the Community Wavefield Demonstration Experiment in north‐central Oklahoma and found that local site noise and not the sensor self‐noise is a fundamental limiter in the resolution of these deployed sensors at frequencies above ∼0.1Hz .

The Thrombin Receptor Antagonist for Clinical Event Reduction in Acute Coronary Syndrome (TRA*CER) trial: study design and rationale.

Science.gov (United States)

2009-09-01

The protease-activated receptor 1 (PAR-1), the main platelet receptor for thrombin, represents a novel target for treatment of arterial thrombosis, and SCH 530348 is an orally active, selective, competitive PAR-1 antagonist. We designed TRA*CER to evaluate the efficacy and safety of SCH 530348 compared with placebo in addition to standard of care in patients with non-ST-segment elevation (NSTE) acute coronary syndromes (ACS) and high-risk features. TRA*CER is a prospective, randomized, double-blind, multicenter, phase III trial with an original estimated sample size of 10,000 subjects. Our primary objective is to demonstrate that SCH 530348 in addition to standard of care will reduce the incidence of the composite of cardiovascular death, myocardial infarction (MI), stroke, recurrent ischemia with rehospitalization, and urgent coronary revascularization compared with standard of care alone. Our key secondary objective is to determine whether SCH 530348 will reduce the composite of cardiovascular death, MI, or stroke compared with standard of care alone. Secondary objectives related to safety are the composite of moderate and severe GUSTO bleeding and clinically significant TIMI bleeding. The trial will continue until a predetermined minimum number of centrally adjudicated primary and key secondary end point events have occurred and all subjects have participated in the study for at least 1 year. The TRA*CER trial is part of the large phase III SCH 530348 development program that includes a concomitant evaluation in secondary prevention. TRA*CER will define efficacy and safety of the novel platelet PAR-1 inhibitor SCH 530348 in the treatment of high-risk patients with NSTE ACS in the setting of current treatment strategies.

A SLANG - TRA translator has been devised for faster, easier programing. The program is realized on a SDS-1604A computer, input data are read from 80 column punch cards and translated into the standard Hollerith 026 code. Programs are processed in batches. A SDS-1604A teletype enables the operator to control the translation. The translator makes it possible to evaluate program processing time. The translator's high speed simplifies program editing and saves manpower

Pawedness Trait Test (PaTRaT—A New Paradigm to Evaluate Paw Preference and Dexterity in Rats

2017-10-01

Full Text Available In rodents, dexterity is commonly analyzed in preference paradigms in which animals are given the chance to use either the left or the right front paws to manipulate food. However, paw preference and dexterity at population and individual levels are controversial as results are incongruent across paradigms. We have therefore developed a semi-quantitative method—the pawdeness trait test (PaTRaT—to evaluate paw preference degree in rats. The PaTRaT consists in a classification system, ranging from +4 to −4 where increasingly positive and negative values reflect the bias for left or right paw use, respectively. Sprague-Dawley male rats were confined into a metal rectangular mesh cylinder, from which they can see, smell and reach sugared rewards with their paws. Due to its size, the reward could only cross the mesh if aligned with its diagonal, imposing additional coordination. Animals were allowed to retrieve 10 rewards per session in a total of four sessions while their behavior was recorded. PaTRaT was repeated 4 and 8 weeks after the first evaluation. To exclude potential bias, rats were also tested for paw fine movement and general locomotion in other behavioral paradigms as well as impulsivity (variable delay-to-signal, VDS, memory and cognitive flexibility (water maze. At the population level 54% of the animals presented a rightward bias. Individually, all animals presented marked side-preferences, >2 and <−2 for left- and right-sided bias, respectively, and this preference was stable across the three evaluations. Inter-rater consistency was very high between two experienced raters and substantial when two additional inexperienced raters were included. Left- and right-biased animals presented no differences in the ability to perform fine movements with any of the forelimbs (staircase and general locomotor performance. Additionally, these groups performed similarly in executive function and memory tasks. In conclusion, PaTRaT is able

La narrazione orale tra bambini ed adulti: da flusso continuo a vena carsica?

Directory of Open Access Journals (Sweden)

Milena Bernardi

2010-02-01

Full Text Available Con il segmento di ricerca che viene presentato nella sua prima fase si prende in esame l’ipotesi di un processo, in atto da tempo, di trasformazione e/o di declino della narrazione orale nel rapporto quotidiano tra adulti e bambini, inteso, in questo specifico contesto, come “spia” dei mutamenti degli stili educativi e degli interscambi tra famiglie ed operatori dei servizi in relazione all’alleanza educativa. La complessità dei filoni di studio che rimandano alla voce “narrazione” negli ambiti delle scienze umane esige la precisazione della curvatura “narrativa” scelta per la ricerca in corso: curvatura che appartiene all’epistemologia della letteratura per l’infanzia e della pedagogia della narrazione in quanto permette di imboccare la strada della ricerca pedagogica rivolta innanzi tutto ai significati che il narrare assume nella relazione educativa e poi ai modi ed alle forme della narrazione che coinvolgono l’infanzia. In un’epoca di grande vitalità e visibilità delle narrazioni, tra cui abbondano le produzioni scritte, illustrate, filmate per l’infanzia, sembra esserci una zona marginale e quasi sommersa della comunicazione narrante che rischia di sfumare in una sorta di oblio. E’ la zona della narrazione orale esperita in praesentia da bambini ed adulti insieme, tessuta con fili di parole che restituiscono senso all’intero arco delle esperienze, tentando di riordinare il disordine che spesso connota la realtà, interpretando, stabilendo connessioni, impregnando di quel senso i vissuti, i fatti, le relazioni, le cose e le parole stesse, ancora, nelle voci. Del rischio e delle conseguenze che possono derivare dalla sua mancanza si occupa questo contributo di ricerca che, dal punto di vista metodologico, si è avvalso e si avvale sia di analisi condotte sul corpus dei testi sia della raccolta di dati e informazioni tramite incontri condotti con la modalità del focus group, con educatrici e genitori.

Neoadjuvant chemotherapy has practical and theoretical advantages over adjuvant chemotherapy strategy in breast cancer (BC) management. Moreover, metronomic delivery has a more favorable toxicity profile. The present study examined the feasibility of neoadjuvant metronomic chemotherapy in two cohorts [HER2+ (TraQme) and HER2− (TAME)] of locally advanced BC. Twenty patients were prospectively enrolled (TraQme, n=9; TAME, n=11). Both cohorts received weekly paclitaxel at 100 mg/m 2 during 8 weeks followed by weekly doxorubicin at 24 mg/m 2 for 9 weeks in combination with oral cyclophosphamide at 100 mg/day (fixed dose). The HER2+ cohort received weekly trastuzumab. The study was interrupted because of safety issues. Thirty-six percent of patients in the TAME cohort and all patients from the TraQme cohort had stage III BC. Of note, 33% from the TraQme cohort and 66% from the TAME cohort displayed hormone receptor positivity in tumor tissue. The pathological complete response rates were 55% and 18% among patients enrolled in the TraQme and TAME cohorts, respectively. Patients in the TraQme cohort had more advanced BC stages at diagnosis, higher-grade pathological classification, and more tumors lacking hormone receptor expression, compared to the TAME cohort. The toxicity profile was also different. Two patients in the TraQme cohort developed pneumonitis, and in the TAME cohort we observed more hematological toxicity and hand-foot syndrome. The neoadjuvant metronomic chemotherapy regimen evaluated in this trial was highly effective in achieving a tumor response, especially in the HER2+ cohort. Pneumonitis was a serious, unexpected adverse event observed in this group. Further larger and randomized trials are warranted to evaluate the association between metronomic chemotherapy and trastuzumab treatment

Pathways of topological rank analysis (PoTRA): a novel method to detect pathways involved in hepatocellular carcinoma.

Science.gov (United States)

Li, Chaoxing; Liu, Li; Dinu, Valentin

2018-01-01

Complex diseases such as cancer are usually the result of a combination of environmental factors and one or several biological pathways consisting of sets of genes. Each biological pathway exerts its function by delivering signaling through the gene network. Theoretically, a pathway is supposed to have a robust topological structure under normal physiological conditions. However, the pathway's topological structure could be altered under some pathological condition. It is well known that a normal biological network includes a small number of well-connected hub nodes and a large number of nodes that are non-hubs. In addition, it is reported that the loss of connectivity is a common topological trait of cancer networks, which is an assumption of our method. Hence, from normal to cancer, the process of the network losing connectivity might be the process of disrupting the structure of the network, namely, the number of hub genes might be altered in cancer compared to that in normal or the distribution of topological ranks of genes might be altered. Based on this, we propose a new PageRank-based method called Pathways of Topological Rank Analysis (PoTRA) to detect pathways involved in cancer. We use PageRank to measure the relative topological ranks of genes in each biological pathway, then select hub genes for each pathway, and use Fisher's exact test to test if the number of hub genes in each pathway is altered from normal to cancer. Alternatively, if the distribution of topological ranks of gene in a pathway is altered between normal and cancer, this pathway might also be involved in cancer. Hence, we use the Kolmogorov-Smirnov test to detect pathways that have an altered distribution of topological ranks of genes between two phenotypes. We apply PoTRA to study hepatocellular carcinoma (HCC) and several subtypes of HCC. Very interestingly, we discover that all significant pathways in HCC are cancer-associated generally, while several significant pathways in subtypes

The industrial radiographic work that uses mobile equipment in Brazil must be in compliance with the National Commission of Nuclear Energy (CNEN) Regulation CNEN-NN 6.04. It states that every works that employs radiographic equipment in occupied areas or public roads requires a specific radiation protection procedure. This procedure must be approved by the CNEN at least fifteen days before starting the job. It is not always possible to the users to get their licensing work at time, because the industrial radiography jobs need immediate actions. Furthermore, the CNEN-NN 6.04 Regulation does not specify what type of information the procedures should involve, so that some important information had been often missed, causing a delaying in the licensing procedures. The corrective and preventive actions taken by the CNEN to optimize this kind of jobs and to overcome bureaucratic difficulties are described. A standard radiation protection procedure is also presented. (authors). 2 refs., 2 tabs

Obesity is a metabolic disorder that has a multifactorial etiology and affects millions of people worldwide. Ghrelin, a hormone coded by the GHRL gene, plays a role in human body composition and appetite. Single nucleotide polymorphisms (SNPs) of the GHRL gene have been associated with obesity and metabolic disorders. To evaluate the association of A-604G SNP of GHRL promoter region with serum ghrelin levels and the risk of obesity in a Mexican population. Two hundred and fifty individuals were enrolled and classified as obese or control subjects (CS) according to BMI. DNA samples, anthropometric measurements and biochemical parameters were obtained from all subjects. The A-604G SNP was genotyped using PCR-RFLPs technique. Ghrelin levels were measured using a commercial enzyme immunoassay. The G/G genotype was more frequent among obese individuals (p ghrelin levels were higher in obese patients (p = 0.004) than in CS, however, significance was lost after adjustment for age (p = 0.088). The G/G genotype was associated with higher levels of serum ghrelin (p = 0.02) independently of the effect of age. The G/G genotype of the A-604G SNP in the GHRL gene is associated with altered serum ghrelin levels and obesity. The A allele was also associated with protection against obesity in this study.

Previous studies suggested that polymorphisms in the coding region of the preproghrelin were involved in the etiology of obesity and might modulate glucose-induced insulin secretion. We evaluated the association of a new variation, -604C>T, in the promoter region of the ghrelin gene, of Leu72Met (247C>A) and of Gln90Leu (265A>T), all haplotype-tagging single nucleotide polymorphisms (SNPs), with measures of insulin sensitivity in 1420 adult individuals. The three SNPs were genotyped using ABI PRISM 7900 HT Sequence Detection System. We used multiple linear regression analysis for quantitative traits and THESIAS software for haplotype analysis. We observed a protective effect exerted by Met72 variant of Leu72Met SNP on insulin resistance parameters; a significant decreasing trend from Leu/Leu to Leu/Met and to Met/Met homozygous subjects in triglycerides, fasting insulin levels and HOMA-IR index (P=0.02, 0.01 and 0.003, respectively), and, consistently, an increase in ghrelin levels (P=0.003) was found. A significant decrease from CC to TC and to TT genotypes in insulin levels and HOMA-IR index was also detected (P=0.00l for both), but only in subjects homozygous for Leu72, where the protective effect of Met72 was not present. The haplotype analysis results supported the data obtained by the evaluation of each single SNP, showing the highest value of insulin levels and HOMA-IR index in the -604(c)247(c) haplotype intermediate value in -604(T)247(C) and lowest value in -604(C)247(A). Our observations suggest a protective role of the Met72 variant and of -604 T allele in modulating insulin resistance. These SNPs or an unknown functional variant in linkage disequilibrium could increase ghrelin levels and probably insulin sensitivity.

Musei post-etnografici: Le trasformazioni dei rapporti tra antropologia e museo in Francia

Full Text Available L’articolo riflette sulle trasformazioni contemporanee dei rapporti tra antropologia e museo in Francia alla luce dell’apertura negli ultimi anni del Musée du quai Branly, del Musée des Civilisations de l'Europe et de la Méditerranée (MUCEM, e del rinnovamento del Musée de l'Homme. La relazione tra musei e antropologia, storicamente più stretta in Francia che in altri contesti nazionali, spiega l’intensità delle reazioni suscitate da queste trasformazioni. La ricostruzione della successione dei progetti di musei etnografici, e in particolare l’ideale del ‘museo-laboratorio’, dimostra il ruolo duraturo del paradigma enciclopedico-naturalista. L’esaurimento del paradigma naturalista, tanto negli stessi musei di storia naturale come il Muséum National d'Histoire Naturelle di Parigi quanto nei musei etnografici, ha prodotto una trasformazione del ruolo dei musei, sancito dal passaggio da un discorso museografico centrato sulla scienza e il razionalismo ad un approccio estetizzante fondato sulle emozioni. Allo stesso tempo, il paradigma naturalista ed evoluzionista rinasce nel nuovo Musée de l'Homme, inaugurato nel 2015. Questi nuovi musei, che possono essere definiti come ‘post-etnografici’, non sono ancora riusciti a fare i conti con la storia e con il loro passato coloniale. Nel contempo, l’antropologia francese si trova di fronte alla sfida di reinventarsi come ‘antropologia post-museo’.

Ghrelin hormone has an important role in a wide range of metabolic and non-metabolic processes. Polymorphisms of ghrelin gene could be associated with a large number of diseases. The aim of this study was to evaluate the association of -604G/A and -501A/C polymorphisms in ghrelin and obestatin prepropeptide gene (GHRL) with polycystic ovary syndrome (PCOS) in a sample of Iranian women. One hundred and fifty-two women with PCOS and 162 age-matched apparently healthy women as control group were enrolled in this study. The study subjects were genotyped for polymorphisms in the ghrelin gene using polymerase chain reaction-restriction fragment length polymorphism-based methods. Biochemical parameters, serum prolactin, luteinizing hormone, follicle stimulating hormone, estradiol, and testosterone were estimated by chemiluminescence assay. Serum lipids and lipoproteins were determined by standard enzymatic methods. The association between the risk of PCOS and ghrelin gene polymorphisms was examined using Multivariate analysis. The frequency of the -604G/A and -501A/C polymorphisms was not statistically different between patients and the control group of women (p = 0.12 and p = 0.21, respectively). A significantly higher level of LDL-C was found in the wild-type AA genotype compared with CC genotype of -501A/C polymorphism (p = 0.02). Our findings indicate that neither -604G/A and nor -501A/C polymorphisms of ghrelin gene are associated with PCOS, but suggest a relation between the presence of polymorphic allele of -501A/C polymorphism and LDL-C level in a sample of Iranian women.

Accademie teatrali fiorentine nel quartiere di Santa Croce tra Sei e Settecento: tra attori dilettanti, gioco d’azzardo e primi tentativi impresariali

Full Text Available Il saggio approfondisce il funzionamento delle accademie teatrali fiorentine a cavallo tra XvII e XvIII secolo sotto più punti di vista: localizzazione dei teatri, repertorio e circolazione degli interpreti, aspetti di amministrazione economica, rapporti con il potere e, nella fattispecie, con la dinastia medicea. Emerge la concentrazione nel quartiere di Santa Croce di Firenze di una buona parte delle accademie di dilettanti, che per alcuni decenni offrono una produzione drammaturgica alternativa a quella del teatro degli attori professionisti, esclusi dal mercato fiorentino nell’ultima fase medicea. Sulle motivazioni di questo fenomeno sono qui proposte ipotesi alternative alla vulgata storiografica che vede in questi anni il nadir culturale nella storia del Granducato e della famiglia al potere. Ci si sofferma, inoltre, sul problema di una possibile definizione di sistema teatrale fiorentino, con particolare attenzione alla disanima dei primi tentativi di adozione di un modello impresariale nel teatro in musica.

Nos últimos anos, o ruído ambiental das grandes cidades, principalmente devido ao tráfego, foi relacionado com diversas patologias, tanto de natureza cardiovascular, como respiratória e inclusivamente com diabetes. Neste trabalho, para além se fazer uma breve descrição dos estudos que relacionam o ruído ambiental com a morbilidade e os diferentes mecanismos biológicos implicados, possíveis de explicar nessas associações; apresentam-se os resultados de um conjunto de investigações que, mediante a Análise de Séries Temporais, relacionam o ruído de tráfego na cidade de Madrid com a mortalidade diária por causas circulatórias, respiratórias e diabetes na faixa etária de maiores de 65 anos. Assim como a mortalidade anual atribuída ao ruído de tráfego em Madrid e a sua comparação com a atribuição às PM2,5.

Chuvas simuladas na intensidade de 64 mm h-1 e duração de 60 a 105 min foram aplicadas em quatro épocas: logo após a semeadura, 30 e 60 dias após a emergência e logo após a colheita do milho. A cobertura do solo propiciada pela cultura de inverno foi reduzida em 90% após o preparo convencional, independentemente da forma de tração. As perdas de solo e água medidas durante o desenvolvimento do milho foram sempre maiores sob preparo convencional do que sob plantio direto, independentemente da forma de tração, exceto logo após a colheita, quando a resteva estava uniformemente distribuída na superfície do solo. No preparo convencional, a erosão na cultura do milho foi, na média das formas de tração, 45% menor, quando antecedida de aveia preta no inverno do que quando antecedida de pousio descoberto. Por sua vez, a cultura do milho, por si só, reduziu a erosão em 60%, na média das formas de tração, comparada à do solo descoberto. A forma de tração influenciou a erosão somente no preparo convencional, com a animal apresentando perdas totais de solo 55 e 15% inferiores à tratorizada, respectivamente na cultura do milho e em solo descoberto. A perda de água por enxurrada foi mais afetada pela forma de tração no preparo convencional, totalizando, em média, 44% na animal e 57% na tratorizada, em relação ao volume total de chuva aplicado.

Full Text Available BACKGROUND: Spinal traction is a relatively popular procedure for increasing the intervertebral space by applying separating forces. The parameters of time and magnitude of the traction forces may influence the outcomes from this procedure and need to be investigated. The duration of the benefits derived from traction is unknown and needs to be determined so that physiotherapists can provide better and more effective treatments. OBJECTIVE: This study analyzed the relationship between load magnitude and time during spinal traction in relation to stature variations. Traction effect duration was also analyzed. METHOD: Fifteen healthy male subjects (23.1 ± 5.77 years; 1.80 ± 0.17 m and 87.0 ± 9.6 kg were assessed under three traction conditions (0, 30 and 60% of body weight, BW of 42 minutes. Stature variation was used to determine intervertebral disc height variation. Stature was assessed every 7 minutes during traction of 42 minutes and every 5 minutes for 45 minutes after traction ceased. RESULTS: 0 and 30% BW traction produced similar gains (6.09 ± 1.89 mm, 5.70 ± 1.88 mm, respectively; p>0.05, while these were smaller (pCONTEXTUALIZAÇÃO: A tração sobre a coluna vertebral é um procedimento relativamente popular para aumentar o espaço inter-vertebral pela aplicação de forças de separação.

Czaban Jaroslaw

2014-09-01

Full Text Available Automatic gearbox gains increasing popularity in Europe. Little interest in diagnosis of such type of transmission in Poland results from the fact of small share in the whole market of operated cars, so there is a lack of availability of special diagnostic devices. These factors cause issues of expensive repairs, often involving a replacement of subassembly to new or aftermarket one. To a small extent some prophylactic diagnostic tests are conducted, which can eliminate future gearbox system failures. In the paper, the proposition of diagnostic system of popular A - 604 gearbox was presented. The authors are seeking for the possibility of using such type of devices to functional elaboration of gearboxes after renovation. The built system pursues the drive of the researched object, connected with simulated load, where special controller, replacing the original one, is responsible for controlling gearbox operation. This way is used to evaluate the mechanic and hydraulic parts' state. Analysis of signal runs, registered during measurements lets conclude about operation correctness, where as comparison with stock data verifies the technical state of an automatic gearbox.

Full Text Available Anal fistula (bhagandara is a chronic inflammatory condition, a tubular structure opening in the ano-rectal canal at one end and surface of perineum/peri-anal skin on the other end. Typically, fistula has two openings, one internal and other external associated with chronic on/off pus discharge on/off pain, pruritis and sometimes passing of stool from external opening. This affects predominantly male patients due to various etiologies viz., repeated peri-anal infections, Crohn′s disease, HIV infection, etc., Complex and atypical variety is encountered in very few patients, which require special treatment for cure. The condition poses difficulty for a surgeon in treating due to issues like patient hesitation, trouble in preparing kṣārasūtra, natural and routine infection with urine, stool etc., and dearth of surgical experts and technique. We would like to report a complex and atypical, single case of anterior, low anal fistula with tract reaching to median raphe of scrotum, which was managed successfully by limited application of kṣārasūtra.

Full Text Available Este trabalho estuda in vitro a resistência à tração de corpos-de-prova de amálgama-resina composta unidos pelo adesivo dental Scotchbond Multi-Uso Plus. Os corpos-de-prova foram divididos em três grupos de dez, sendo que cada corpo era o resultado da união de dois discos, um de amálgama e outro de resina composta. Esses discos foram obtidos dentro de cilindros de baquelite e sofreram acabamento superficial com lixa de grana 600. Pretendeu-se simular a técnica do amalcomp e verificar a resistência à tração entre o amálgama e a resina composta em diferentes condições de oxidação do amálgama. Dos resultados obtidos e mediante análise de variância e teste de Tukey a 5%, pôde-se concluir que: o Grupo 3, que ficou na saliva artificial por trinta dias e portanto sofreu maior oxidação, apresenta resistência à tração superior e estatisticamente significante em relação aos grupos 1 e 2; o Grupo 2, que ficou na saliva por sete dias e sofreu menor oxidação, não apresenta resistência à tração estatisticamente superior ao Grupo 1 de amálgama recém-condensado.

A review of similar events at previous times in the past shows that operators in international financial markets have very short memories, since most of the aspects of the current crisis have occurred in the past. This is borne out by considering the international debt problem between the first and second world wars. The major difference between then and now is that the interwar period was a time of transition from a sterling-dominated trading system to one dominated by the US dollar. Many of today's problems stem from this continuing dollar domination.JEL: N24

Numerical Calculation of Coherent Synchrotron Radiation Effects Using TraFiC4

International Nuclear Information System (INIS)

Kabel, Andreas C.

2000-01-01

Coherent synchrotron radiation (CSR) occurs when short bunches travel on strongly bent trajectories. Its effects on high-quality beams can be severe and are well understood qualitatively. For quantitative results, however, one has to rely on numerical methods. There exist several simulation codes utilizing different approaches. The authors describe in some detail the code TraFiC 4 developed at DESY for design and analysis purposes, which approaches the problem from first principles and solves the equations of motion either perturbatively or self-consistently. They present some calculational results and comparison with experimental data. Also, they give examples of how the code can be used to design beamlines with minimal emittance growth due to CSR

Numerical modelling of the V-J combinations of the T cell receptor TRA/TRD locus.

Florence Thuderoz

2010-02-01

Full Text Available T-Cell antigen Receptor (TR repertoire is generated through rearrangements of V and J genes encoding alpha and beta chains. The quantification and frequency for every V-J combination during ontogeny and development of the immune system remain to be precisely established. We have addressed this issue by building a model able to account for Valpha-Jalpha gene rearrangements during thymus development of mice. So we developed a numerical model on the whole TRA/TRD locus, based on experimental data, to estimate how Valpha and Jalpha genes become accessible to rearrangements. The progressive opening of the locus to V-J gene recombinations is modeled through windows of accessibility of different sizes and with different speeds of progression. Furthermore, the possibility of successive secondary V-J rearrangements was included in the modelling. The model points out some unbalanced V-J associations resulting from a preferential access to gene rearrangements and from a non-uniform partition of the accessibility of the J genes, depending on their location in the locus. The model shows that 3 to 4 successive rearrangements are sufficient to explain the use of all the V and J genes of the locus. Finally, the model provides information on both the kinetics of rearrangements and frequencies of each V-J associations. The model accounts for the essential features of the observed rearrangements on the TRA/TRD locus and may provide a reference for the repertoire of the V-J combinatorial diversity.

Reed, M.F.

1994-01-01

Idaho State University, in cooperation with the U.S. Geological Survey, and the U.S. Department of Energy, collected 57 samples of sedimentary interbeds at 19 sites at the Idaho National Engineering Laboratory (INEL) for mineralogical analysis. Previous work by the U.S. Geological Survey on surficial sediments showed that ratios detrital of quartz, total feldspars, and calcite can be used to distinguish the sedimentary mineralogy of specific stream drainages at the INEL. Semi-quantitative x-ray diffraction analyses were used to determine mineral abundances in the sedimentary interbeds. Samples were collected from wells at the New Production Reactor (NPR) area, Idaho Chemical Processing Plant (ICPP), Test Reactor Area (TRA), miscellaneous sites, Radioactive Waste Management Complex (RWMC), Naval Reactors Facility (NRF), and Test Area North (TAN). Normalized mean percentages of quartz, feldspar, and carbonate were calculated from sample data sets at each site. Percentages for quartz, feldspar, and carbonate from the NPR, ICPP, TRA, miscellaneous sites, RWMC, and NRF ranged from 37 to 59, 26 to 40, and 5 to 25, respectively. Percentages for quartz, feldspar, and carbonate from wells at Test Area North (TAN) were 24, 10, and 66, respectively. Mineralogical data indicate that sedimentary interbed samples collected from the NPR, ICPP, TRA, miscellaneous sites, RWMC, and NRF correlate with surficial sediment samples from the present day Big Lost River. Sedimentary interbeds from TAN sites correlate with surficial sediment samples from Birch Creek. These correlations suggest that the sources for the sediments at and near the INEL have remained relatively consistent for the last 580,000 years. 12 refs., 4 figs., 3 tabs

  O filósofo Sêneca (c.4 a.C.-65 d.C. é autor de oito tragédias latinas às quais se atribui, regra geral, elevado grau de “influência” na literatura dramática produzida na Inglaterra da virada do século XVI para o XVII. Sem recorrer ao usual método de localizar citações ou equivalências textuais, propõe-se aqui reconhecer os traços da elocução senequiana em Shakespeare a partir da identificação de dispositivos da retórica antiga e de suas correspondências em cenas específicas de Richard III, Hamlet e The Tempest. A tradução dessas peças a partir do latim ou do inglês deve refletir o domínio e a intenção dos autores no uso de tais expedientes retóricos.

Full Text Available RESUMO Um estudo de campo foi realizado em um trecho de aproximadamente 70 km do rio Piabanha, localizado entre Petrópolis e Areal, na região serrana do Estado do Rio de Janeiro, para estimar as características de transporte e dispersão de contaminantes usando técnicas de traçadores fluorescentes. A análise dos resultados de dois trabalhos de campo, realizados no outono de 2012, permitiu determinar os valores de tempo de trânsito, vazão líquida, velocidade média e coeficiente de dispersão longitudinal. Utilizou-se os dados de vazão e velocidade média obtidos nos ensaios com traçadores para calibrar o modelo hidrodinâmico unidimensional Hydrologic Engineering Center’s River Analysis System (HEC-RAS. Considerando que parâmetros hidráulicos obtidos por métodos clássicos em rios com geometria muito irregular, como a do rio Piabanha, não são adequados para representar as características médias de um trecho, os ensaios com traçadores representaram uma boa alternativa para obtenção de parâmetros necessários a modelos hidrodinâmicos. Os resultados obtidos pelo modelo HEC-RAS apresentaram ótima concordância com os dados obtidos por meio dos ensaios com traçadores fluorescentes.

Component Fragility Research Program: Phase 1 component prioritization

Holman, G.S.; Chou, C.K.

1987-06-01

Current probabilistic risk assessment (PRA) methods for nuclear power plants utilize seismic ''fragilities'' - probabilities of failure conditioned on the severity of seismic input motion - that are based largely on limited test data and on engineering judgment. Under the NRC Component Fragility Research Program (CFRP), the Lawrence Livermore National Laboratory (LLNL) has developed and demonstrated procedures for using test data to derive probabilistic fragility descriptions for mechanical and electrical components. As part of its CFRP activities, LLNL systematically identified and categorized components influencing plant safety in order to identify ''candidate'' components for future NRC testing. Plant systems relevant to safety were first identified; within each system components were then ranked according to their importance to overall system function and their anticipated seismic capacity. Highest priority for future testing was assigned to those ''very important'' components having ''low'' seismic capacity. This report describes the LLNL prioritization effort, which also included application of ''high-level'' qualification data as an alternate means of developing probabilistic fragility descriptions for PRA applications

Phylogenetic reconstruction of the Legionella pneumophila Philadelphia-1 laboratory strains through comparative genomics.

Directory of Open Access Journals (Sweden)

Chitong Rao

Full Text Available Over 20 years ago, two groups independently domesticated Legionella pneumophila from a clinical isolate of bacteria collected during the first recognized outbreak of Legionnaires' disease (at the 1976 American Legion's convention in Philadelphia. These two laboratory strains, JR32 and Lp01, along with their derivatives, have been disseminated to a number of laboratories around the world and form the cornerstone of much of the research conducted on this important pathogen to date. Nevertheless, no exhaustive examination of the genetic distance between these strains and their clinical progenitor has been performed thus far. Such information is of paramount importance for making sense of several phenotypic differences observed between these strains. As environmental replication of L. pneumophila is thought to exclusively occur within natural protozoan hosts, retrospective analysis of the domestication and axenic culture of the Philadelphia-1 progenitor strain by two independent groups also provides an excellent opportunity to uncover evidence of adaptation to the laboratory environment. To reconstruct the phylogenetic relationships between the common laboratory strains of L. pneumophila Philadelphia-1 and their clinical ancestor, we performed whole-genome Illumina resequencing of the two founders of each laboratory lineage: JR32 and Lp01. As expected from earlier, targeted studies, Lp01 and JR32 contain large deletions in the lvh and tra regions, respectively. By sequencing additional strains derived from Lp01 (Lp02 and Lp03, we retraced the phylogeny of these strains relative to their reported ancestor, thereby reconstructing the evolutionary dynamics of each laboratory lineage from genomic data.

La «speciale provvidenza» nella caduta di una falena: ibridismi woolfiani tra saggio e short story

Full Text Available Il contributo intende mettere in luce le dinamiche di ibridazione tra i generi saggio e novella nella prosa breve di Virginia Woolf, in particolare in quegli esemplari di saggi che presentano delle caratteristiche smaccatamente immaginifiche e narrative che li distanziano nettamente dall’ideale di saggio quale «breve testo nonfinzionale in prosa». Nota al grande pubblico proprio per la sua programmatica ricerca di codici espressivi sempre nuovi e per le sperimentazioni con i generi più disparati, nel caso della prosa breve Woolf riesce con successo a infrangere i confini tra argomentativo e narrativo per giungere a una forma mediana che trae la sua identità sia dalla fiction che dalla nonfiction. Tramite un’analisi di alcune tra le short stories e i saggi più significativi, il contributo vuole essere uno spunto per una più ampia riflessione su quanto la mescolanza di stilemi diversi sia non solo un tratto letterario tipico della letteratura modernista, quanto piuttosto la risposta a una necessità di trovare una via altra nel panorama letterario, quasi una pulsione creativa primigenia che, nel caso delle contaminazioni tra saggio e narrativa breve, può essere affiancata al concetto di saggismo proposto da Robert Musil. The Death of the Moth, Street Haunting e molti altri saggi woolfiani permettono quindi di ricalibrare le demarcazioni fra generi, e di ripensare gli idealtipi che nella mentalità comune sono assurti a modelli e per l’uno e per l’altro dei due generi brevi in prosa, che in questa sede rappresentano i limiti estremi dello spettro di analisi. My paper aims at evaluating the hybridizing techniques that V. Woolf deployed in her shorter prose to blur the edges between the essay and the short story, in particular in those essayistic specimens that present some markedly imaginative features which undermine the ideal of the essay as a «brief, nonfictional prose piece». Woolf is justly renowned for her programmatic and

Conjugative Plasmid Transfer in Xylella fastidiosa Is Dependent on tra and trb Operon Functions.

Science.gov (United States)

Burbank, Lindsey P; Van Horn, Christopher R

2017-11-01

The insect-transmitted plant pathogen Xylella fastidiosa is capable of efficient horizontal gene transfer (HGT) and recombination. Natural transformation occurs at high rates in X. fastidiosa , but there also is evidence that certain strains of X. fastidiosa carry native plasmids equipped with transfer and mobilization genes, suggesting conjugation as an additional mechanism of HGT in some instances. Two operons, tra and trb , putatively encoding a conjugative type IV secretion system, are found in some but not all X. fastidiosa isolates, often on native plasmids. X. fastidiosa strains that carry the conjugative transfer genes can belong to different subspecies and frequently differ in host ranges. Using X. fastidiosa strain M23 ( X. fastidiosa subsp. fastidiosa ) or Dixon ( X. fastidiosa subsp. multiplex ) as the donor strain and Temecula ( X. fastidiosa subsp. fastidiosa ) as the recipient strain, plasmid transfer was characterized using the mobilizable broad-host-range vector pBBR5pemIK. Transfer of plasmid pBBR5pemIK was observed under in vitro conditions with both donor strains and was dependent on both tra and trb operon functions. A conjugative mechanism likely contributes to gene transfer between diverse strains of X. fastidiosa , possibly facilitating adaptation to new environments or different hosts. IMPORTANCE Xylella fastidiosa is an important plant pathogen worldwide, infecting a wide range of different plant species. The emergence of new diseases caused by X. fastidiosa , or host switching of existing strains, is thought to be primarily due to the high frequency of HGT and recombination in this pathogen. Transfer of plasmids by a conjugative mechanism enables movement of larger amounts of genetic material at one time, compared with other routes of gene transfer such as natural transformation. Establishing the prevalence and functionality of this mechanism in X. fastidiosa contributes to a better understanding of HGT, adaptation, and disease emergence

Ranking protective coatings: Laboratory vs. field experience

Science.gov (United States)

Conner, Jeffrey A.; Connor, William B.

1994-12-01

Environmentally protective coatings are used on a wide range of gas turbine components for survival in the harsh operating conditions of engines. A host of coatings are commercially available to protect hot-section components, ranging from simple aluminides to designer metallic overlays and ceramic thermal barrier coatings. A variety of coating-application processes are available, and they range from simple pack cementation processing to complex physical vapor deposition, which requires multimillion dollar facilities. Detailed databases are available for most coatings and coating/process combinations for a range of laboratory tests. Still, the analysis of components actually used in engines often yields surprises when compared against predicted coating behavior from laboratory testing. This paper highlights recent work to develop new laboratory tests that better simulate engine environments. Comparison of in-flight coating performance as well as industrial and factory engine testing on a range of hardware is presented along with laboratory predictions from standard testing and from recently developed cyclic burner-rig testing.

Computed Tomography (CT) and, more recently, ultrasound (US), have proved excellent tools for quantifying adipose tissue distribution. Body fat distribution is an important factor in the treatment of obesity and its complications. In this work it is investigated the correlation between CT and US measurements in pediatric obesity. Forty obese children and adolescents aged 4.1-14.8 years were submitted to CT and US. Intra-abdominal, subcutaneous and total body fat were calculated (in cm{sup 2}), with the CT image analysis software. The rectus muscle-spine and rectus muscle-aorta distances, as indicative of visceral fat thickness, were measured on US images with(out) compression. The distance between skin fat and fat-rectus muscle interfaces was measured as subcutaneous fat thickness. US-CT findings have been compared with other morphometric variables-i.e., patient's (ideal) body weight and skin fold measures. A statistically significant correlation was found between the CT measurement of visceral fat and the aorta-rectus muscle and rectus muscle-spine distances (r=0.80 and 0.74, respectively). The US measurements of subcutaneous fat were correlated with CT subcutaneous fat area (r=0.82). No correlation was found between overweight, as calculated by body mass index, and CT or US fat. In conclusions, the findings indicate that US is as useful as CT in evaluating body fat distribution in pediatric obesity.

A Caenorhabditis elegans wild type defies the temperature-size rule owing to a single nucleotide polymorphism in tra-3.

Directory of Open Access Journals (Sweden)

2007-03-01

Full Text Available Ectotherms rely for their body heat on surrounding temperatures. A key question in biology is why most ectotherms mature at a larger size at lower temperatures, a phenomenon known as the temperature-size rule. Since temperature affects virtually all processes in a living organism, current theories to explain this phenomenon are diverse and complex and assert often from opposing assumptions. Although widely studied, the molecular genetic control of the temperature-size rule is unknown. We found that the Caenorhabditis elegans wild-type N2 complied with the temperature-size rule, whereas wild-type CB4856 defied it. Using a candidate gene approach based on an N2 x CB4856 recombinant inbred panel in combination with mutant analysis, complementation, and transgenic studies, we show that a single nucleotide polymorphism in tra-3 leads to mutation F96L in the encoded calpain-like protease. This mutation attenuates the ability of CB4856 to grow larger at low temperature. Homology modelling predicts that F96L reduces TRA-3 activity by destabilizing the DII-A domain. The data show that size adaptation of ectotherms to temperature changes may be less complex than previously thought because a subtle wild-type polymorphism modulates the temperature responsiveness of body size. These findings provide a novel step toward the molecular understanding of the temperature-size rule, which has puzzled biologists for decades.

The bottlenose dolphin (Tursiops truncatus) is a mammal that belongs to the Cetartiodactyla and have lived in marine ecosystems for nearly 60 millions years. Despite its popularity, our knowledge about its adaptive immunity and evolution is very limited. Furthermore, nothing is known about the genomics and evolution of dolphin antigen receptor immunity. Here we report a evolutionary and expression study of Tursiops truncatus T cell receptor gamma (TRG) and alpha/delta (TRA/TRD) genes. We have identified in silico the TRG and TRA/TRD genes and analyzed the relevant mature transcripts in blood and in skin from four subjects. The dolphin TRG locus is the smallest and simplest of all mammalian loci as yet studied. It shows a genomic organization comprising two variable (V1 and V2), three joining (J1, J2 and J3) and a single constant (C), genes. Despite the fragmented nature of the genome assemblies, we deduced the TRA/TRD locus organization, with the recent TRDV1 subgroup genes duplications, as it is expected in artiodactyls. Expression analysis from blood of a subject allowed us to assign unambiguously eight TRAV genes to those annotated in the genomic sequence and to twelve new genes, belonging to five different subgroups. All transcripts were productive and no relevant biases towards TRAV-J rearrangements are observed. Blood and skin from four unrelated subjects expression data provide evidence for an unusual ratio of productive/unproductive transcripts which arise from the TRG V-J gene rearrangement and for a "public" gamma delta TR repertoire. The productive cDNA sequences, shared both in the same and in different individuals, include biases of the TRGV1 and TRGJ2 genes. The high frequency of TRGV1-J2/TRDV1- D1-J4 productive rearrangements in dolphins may represent an interesting oligo-clonal population comparable to that found in human with the TRGV9- JP/TRDV2-D-J T cells and in primates. Although the features of the TRG and TRA/TRD loci organization reflect

Full Text Available Ci si può chiedere quale sia il motivo che spinge ad affrontare la non facile prova consistente nel delineare un percorso di riflessione in chiave filosofica intorno al concetto di “popolo” prendendo in esame il periodo che va dalla prima alla tarda modernità, sino a sfiorare (almeno l’epoca della quale noi, uomini e donne del presente, siamo protagonisti, il più delle volte molto perplessi e parecchio disorientati.Il perché sta nel tentativo di mostrare che, per quanto questo lungo periodo sia, a proposito del nostro argomento, parecchio complesso e contraddistinto da un esteso pluralismo di punti di vista, presenta però, a mio avviso, almeno una caratteristica unitaria. Si tratta della difficoltà di articolare teoreticamente un concetto di “popolo” sul quale non gravino quei limiti sui quali vorrei concentrare l’attenzione: limiti ovviamente non secondari, ma tali da compromettere gravemente il concetto in questione.In tutto il tragitto che proverò a tracciare, non vorrei semplicemente procedere prendendo nota dei punti oscuri rinvenibili in questa o quella concezione di “popolo”, e così mettere in atto una sorta d’incolore e, tutto sommato, ridondante elenco che collochi uno dopo l’altro gli autori come in una galleria dei nobili fallimenti della filosofia politica dal ‘500 a oggi. La posta in gioco è ben diversa. La presento, per ora molto concisamente, come segue.Nel De republica di Cicerone – importante sintesi di una già consolidata tradizione – è evidente la corrispondenza concettuale tra “res publica” e “populus”: la società politica si dà solo in presenza di un’associazione tenuta insieme “per accordo nell’osservare la giustizia” e “per comunanza di interessi”.

The article aims to give an overview of the system of public health laboratory quality management in Thailand and to produce a strengths, weaknesses, opportunities and threats (SWOT) analysis that is relevant to public health laboratories in the country. The systems for managing laboratory quality that are currently employed were described in the first component. The second component was a SWOT analysis, which used the opinions of laboratory professionals to identify any areas that could be improved to meet quality management systems. Various quality management systems were identified and the number of laboratories that met both international and national quality management requirements was different. The SWOT analysis found the opportunities and strengths factors offered the best chance to improve laboratory quality management in the country. The results are based on observations and brainstorming with medical laboratory professionals who can assist laboratories in accomplishing quality management. The factors derived from the analysis can help improve laboratory quality management in the country. This paper provides viewpoints and evidence-based approaches for the development of best possible practice of services in public health laboratories.

Since the late 1960's, strong emphasis has been given to quality assurance in the nuclear industry, particularly to that part involved in nuclear reactors. This emphasis has had impact on the analytical chemistry laboratory because of the importance of analytical measurements in the certification and acceptance of materials used in the fabrication and construction of reactor components. Laboratory quality assurance, in which the principles of quality assurance are applied to laboratory operations, has a significant role to play in processing, fabrication, and construction programs of the nuclear industry. That role impacts not only process control and material certification, but also safeguards and nuclear materials accountability. The implementation of laboratory quality assurance is done through a program plan that specifies how the principles of quality assurance are to be applied. Laboratory quality assurance identifies weaknesses and deficiencies in laboratory operations and provides confidence in the reliability of laboratory results. Such confidence in laboratory measurements is essential to the proper evaluation of laboratories participating in the Safeguards Analytical Laboratory Evaluation (SALE) Program

L’alienazione della donna tra esibizione e occultamento del corpo: dall’oscenità alla costruzione tecnica

Directory of Open Access Journals (Sweden)

Ines Testoni

2013-06-01

Full Text Available L’articolo discute della contrapposizione tra la modalità italiana di considerare il corpo della donna, quale mero oggetto di desiderio sessuale, attraverso la sua esibizione e ildenudamento mediatici versus quella musulmana che, invece, lo nasconde sotto khimar,jilbab o burqa. L'analisi fa perno sui diritti umani fondamentali che nel loro percorsostorico, promuovono il primato dell’individuo e della sua autodeterminazione, per arri-vare a considerare i concetti di alienazione e di oscenità e verificare come le due posi-zioni siano in continuità. Si discute, quindi, delle possibili cause che, anche nell’attualesocietà occidentale, potrebbero ripristinare forme di tradizionalismo, a partire dalla stessa volontà delle donne.

Design guidance for fracture-critical components at Lawrence Livermore National Laboratory

International Nuclear Information System (INIS)

Streit, R.D.

1982-01-01

Fracture is an important design consideration for components whose sudden and catastrophic failure could result in a serious accident. Elements of fracture control and fracture mechanics design methods are reviewed. Design requirements, which are based on the consequences of fracture of a given component, are subsequently developed. Five categories of consequences are defined. Category I is the lowest risk, and relatively lenient design requirements are employed. Category V has the highest potential for injury, release of hazardous material, and damage. Correspondingly, the design requirements for these components are the most stringent. Environmental, loading, and material factors that can affect fracture safety are also discussed

Transport of contaminants from energy-process-waste leachates through subsurface soils and soil components: laboratory experiments

International Nuclear Information System (INIS)

Wangen, L.E.; Stallings, E.A.; Walker, R.D.

1982-08-01

The subsurface transport and attenuation of inorganic contaminants common to a variety of energy process waste leachates are being studied using laboratory column methods. Anionic species currently being emphasized are As, B, Mo, and Se. Transport of the cations Cd and Ni is also being studied. The solid adsorbents consist of three soil mineral components (silica sand, kaolinite, and goethite), and four subsurface soils (a dunal sand, an oxidic sandy clay loam, an acidic clay loam, and an alkaline clay loam). Breakthrough patterns of these species from packed soil columns are followed by monitoring eluent concentrations vs time under carefully controlled laboratory conditions. This report describes the experimental methods being used, the results of preliminary batch adsorption studies, and the results of column experiments completed through calendar year 1981. Using column influent concentrations of about 10 mg/l, adsorption (mmoles/100 g) has been determined from the eluent volume corresponding to 50% breakthrough. On silica sand, kaolinite, dunal sand, and goethite, respectively, these are 2.0 x 10 -4 , 0.020, 0.013, and 0.31 for cadmium, 4.4 x 10 -4 , 0.039, 0.020, and 0.98 for nickel. On kaolinite, dunal sand, and goethite, respectively, adsorption values (mmoles/100 g) are As (0.24, 0.019, and 20.5), B (0.041, 0.0019, and 1.77), Mo (0.048, 0.0010, and 5.93), and Se (0.029, 0.00048, and 1.30). Arsenic is the most highly adsorbed contaminant species and goethite has the largest adsorption capacity of the adsorbents

An elementary components of variance analysis for multi-center quality control

International Nuclear Information System (INIS)

Munson, P.J.; Rodbard, D.

1977-01-01

The serious variability of RIA results from different laboratories indicates the need for multi-laboratory collaborative quality control (QC) studies. Statistical analysis methods for such studies using an 'analysis of variance with components of variance estimation' are discussed. This technique allocates the total variance into components corresponding to between-laboratory, between-assay, and residual or within-assay variability. Components of variance analysis also provides an intelligent way to combine the results of several QC samples run at different evels, from which we may decide if any component varies systematically with dose level; if not, pooling of estimates becomes possible. We consider several possible relationships of standard deviation to the laboratory mean. Each relationship corresponds to an underlying statistical model, and an appropriate analysis technique. Tests for homogeneity of variance may be used to determine if an appropriate model has been chosen, although the exact functional relationship of standard deviation to lab mean may be difficult to establish. Appropriate graphical display of the data aids in visual understanding of the data. A plot of the ranked standard deviation vs. ranked laboratory mean is a convenient way to summarize a QC study. This plot also allows determination of the rank correlation, which indicates a net relationship of variance to laboratory mean. (orig.) [de

Full Text Available Attilio Pini, classe 1930, dai tre ai sedici anni ha vissuto in Somalia dove la sua famiglia si trasferì a seguito della malattia della madre Anna. Rientrato in Italia si è laureato in Medicina Veterinaria all'Università di Torino, città nella quale era stato mandato a finire il Liceo. È stato per un po' all'IZS del Piemonte ma poco dopo ha abbandonato la comodità del posto fisso e nel 1962 è tornato in Africa per andare a lavorare al Veterinary Research Laboratory di Kabete, in Kenya, dove è nata nel 1967 la sua a prima figlia Barbara. Si è poi spostato in Sudafrica, dove nel 1971 è nato il secondo figlio Stefano, all'Onderstepoort Veterinary Research Institute di Pretoria di cui è diventato in seguito vice direttore. A causa delle tensioni politiche e razziali, spinto anche dalla moglie Ilaria (da cui si separerà poco dopo decise di rientrare in Italia, a Ventimiglia, ritrovandosi suo malgrado a cambiare completamente vita e finire a gestire un campeggio. Sarà il prof. Adriano Mantovani a recuperarlo alla professione convincendolo ad andare in Zambia per lavorare a un progetto di cooperazione finanziato dal Ministero degli Affari Esteri. Dopo quell'esperienza seguiranno altre missioni in Bangladesh, ancora in Zambia, in Salvador ed Eritrea. Sul finire degli anni '80 Attilio Pini è tornato definitivamente in Italia dove ha collaborato con l'Istituto Superiore di Sanità, si è risposato con Nadia e, nel 1989, ha iniziato a lavorare per l'IZS di Teramo dove tuttora presta servizio. In questo agile libro è racchiusa l'avvincente storia di un "uomo senza radici e senza consuetudini" narrata in prima persona, senza filtri, con una capacità di sintesi rara. Tanti gli aneddoti sulla sua famiglia della media borghesia che aveva "la tipica servitù dei paesi coloniali": la figura dell'amata madre che "non aveva molta simpatia per i fascisti", del padre Ugo, Capo di Stato Maggiore in Somalia ma anch'egli molto critico verso il regime

Full Text Available Background: Laboratory services are essential at all stages of the tuberculosis care cascade, from diagnosis and drug resistance testing to monitoring response to treatment. Enabling access to quality services is a challenge in low-resource settings. Implementation of a strong quality management system (QMS and laboratory accreditation are key to improving patient care. Objectives: The study objective was to determine the status of QMS implementation and progress towards accreditation of National Tuberculosis Reference Laboratories (NTRLs in the African Region. Method: An online questionnaire was administered to NTRL managers in 47 World Health Organization Regional Office for Africa member states in the region, between February and April 2015, regarding the knowledge of QMS tools and progress toward implementation to inform strategies for tuberculosis diagnostic services strengthening in the region. Results: A total of 21 laboratories (43.0% had received SLMTA/TB-SLMTA training, of which 10 had also used the Global Laboratory Initiative accreditation tool. However, only 36.7% of NTRLs had received a laboratory audit, a first step in quality improvement. Most NTRLs participated in acid-fast bacilli microscopy external quality assurance (95.8%, although external quality assurance for other techniques was lower (60.4% for first-line drug susceptibility testing, 25.0% for second-line drug susceptibility testing, and 22.9% for molecular testing. Barriers to accreditation included lack of training and accreditation programmes. Only 28.6%of NTRLs had developed strategic plans and budgets which included accreditation. Conclusion: Good foundations are in place on the continent from which to scale up accreditation efforts. Laboratory audits should be conducted as a first step in developing quality improvement action plans. Political commitment and strong leadership are needed to drive accreditation efforts; advocacy will require clear evidence of patient

Individuals with low back pain (LBP) have reduced function of the transversus abdominis (TrA) and lumbar multifidus (LM) muscles. Biofeedback during exercise may increase the ability to contract the TrA and LM muscles compared with exercise alone. To compare TrA preferential activation ratio (PAR) and the percent change in LM-muscle thickness in patients with LBP history before and after exercise with or without biofeedback. Controlled laboratory study. University research laboratory. 20 LBP individuals, 10 exercise alone and 10 exercise with biofeedback. Patients were allotted to tabletop exercises in isolation or tabletop exercises with visual, auditory, and tactile biofeedback. TrA PAR and percent change in LM-muscle thickness. There were no differences between groups at baseline (all P > .05). Nonparametric statistics showed decreased resting muscle thickness for total lateral abdominal-wall muscles (P = .007) but not TrA (P = .410) or LM (P = .173). Percent TrA thickness increased from table to standing positions before (P = .006) and after exercise (P = .009). TrA PAR increased after exercise (pre 0.01 ± 0.02, post 0.03 ± 0.04, P = .033) for all patients and for exercise with biofeedback (pre 0.02 ± 0.01, post 0.03 ± 0.01, P = .037) but not for exercise alone (pre 0.01 ± 0.02, post 0.02 ± 0.05, P = .241). No group differences were observed for TrA PAR before (exercise 0.01 ± 0.02, exercise with biofeedback 0.02 ± 0.01, P = .290) or after exercise (exercise 0.02 ± 0.05, exercise with biofeedback 0.03 ± 0.01, P = .174). There were no group differences in LM percent change before exercise (P = .999) or after exercise (P = .597). In addition, no changes were observed in LM percent change as a result of exercise among all participants (P = .391) or for each group (exercise P = .508, exercise with biofeedback P = .575). TrA PAR increased after a single session of exercises, whereas no thickness changes occurred in LM.

Stops with gaps are currently used to support components and piping: it is simple, low cost, efficient and permits free thermal expansion. In order to keep the nonlinear nature of stops, such design is often modeled by beam elements (for the component) and nonlinear springs (for the stops). This paper deals with the validity and the limits of these models through the comparison of computational and experimental results. The experimental results come from impact laboratory tests on a simplified mockup. (orig.)

Full Text Available O objetivo deste trabalho foi propor uma abordagem com enfoque em traços distintivos para o Modelo de Oposições Múltiplas e testar sua aplicação em um sujeito falante do Português Brasileiro. O Modelo foi aplicado em um sujeito do sexo masculino, com desvio fonológico moderado-severo e idade de seis anos e meio. Após avaliação fonológica, procedeu-se à seleção dos sons-alvo. Considerou-se o sistema fonológico inicial, bem como os traços distintivos alterados ([+voz], [+soante], [+aproximante], [coronal/±anterior], [-contínuo]. Os traços com maior número de alterações eram [+voz, +soante, +aproximante], justificando a escolha dos seguintes sons-alvo para tratamento: /r/ x /l/ x // x // x /z/, em onset medial.Tendo como base a aplicação desse modelo em falantes do inglês, percebeu-se a necessidade de introduzir alguns procedimentos, como: a escolha dos sons-alvo a partir dos traços distintivos alterados e a estrutura da sessão terapêutica. Ao final, o sujeito foi reavaliado a fim de verificar as aquisições no sistema fonológico. Após dez sessões de fonoterapia,o sujeito adquiriu os fonemas /l, , , z/, generalizando-os para outras posições na palavra (/Z/ e /l/ em onset inicial. Verificou-se, também, a ocorrência de generalização para a mesma classe e para outras classes de sons (/b/, /d/, /g/, /v/. No entanto, o fonema /r/ não foi adquirido. Esta proposta mostrou-se efetiva, pois o sujeito apresentou melhora em seu sistema fonológico com poucas sessões terapêuticas. Pôde-se observar que o Modelo de Oposições Múltiplas, utilizando a abordagem com base em traços distintivos é eficaz, pois favoreceu diversas mudanças fonológicas.The aim of this study was to propose an approach based on distinctive features for the Multiple Oppositions Model, and to test its application on a Brazilian Portuguese speaker.

Gullate, Mary

African American women (AAW) are 25% more likely to present with late stage breast cancer and 20% more likely to die from their disease than Caucasian women. Researchers report that a treatment delay of 3 months is a significant factor in breast cancer mortality. Socioeconomic factors, lack of access and knowledge, spiritual and religious beliefs, fear and fatalism are reported as contributing factors to screening delays. Studies have primarily applied the Health Belief Model (HBM) and modified versions like the Champion HBM to preventive health practices. Neither have significant inclusion of spirituality or religiosity. The TRA/TPB focus on beliefs, intent and attitude as individual determinants of the likelihood of performing a specific behavior; but have not had wide utility in studies related to screening delays among AAW. This paper explores the utility of applying the TRA/TPB as the theoretical framework for determining cultural relevance of spirituality and religiosity to screening delays among AAW.

Comparison of Tritium Component Failure Rate Data

Published failure rate values from the US Tritium Systems Test Assembly, the Japanese Tritium Process Laboratory, the German Tritium Laboratory Karlsruhe, and the Joint European Torus Active Gas Handling System have been compared. This comparison is on a limited set of components, but there is a good variety of data sets in the comparison. The data compared reasonably well. The most reasonable failure rate values are recommended for use on next generation tritium handling system components, such as those in the tritium plant systems for the International Thermonuclear Experimental Reactor and the tritium fuel systems of inertial fusion facilities, such as the US National Ignition Facility. These data and the comparison results are also shared with the International Energy Agency cooperative task on fusion component failure rate data

The transferable potential for a phase equilibria force field in its united-atom version, TraPPE_UA, is evaluated for 41 polar liquids that include alcohols, thiols, ethers, sulfides, aldehydes, ketones, and esters to determine its ability to reproduce experimental properties that were not included in the parametrization procedure. The intermolecular force field parameters for pure components were fit to reproduce experimental boiling temperature, vapor-liquid coexisting densities, and critical point (temperature, density, and pressure) using Monte Carlo simulations in different ensembles. The properties calculated in this work are liquid density, heat of vaporization, dielectric constant, surface tension, volumetric expansion coefficient, and isothermal compressibility. Molecular dynamics simulations were performed in the gas and liquid phases, and also at the liquid-vapor interface. We found that relative error between calculated and experimental data is 1.2% for density, 6% for heat of vaporization, and 6.2% for surface tension, in good agreement with the experimental data. The dielectric constant is systematically underestimated, and the relative error is 37%. Evaluating the performance of the force field to reproduce the volumetric expansion coefficient and isothermal compressibility requires more experimental data.

In the framework of the EU-FP7 MULTIBIODOSE project, two protocols using OSL of resistors removed from the circuit board of mobile phones were developed with the aim to use the resistors as fortuitous dosimeters in the event of a large scale radiological accident. This paper presents the results of an inter-laboratory comparison carried out under the umbrella of EURADOS. The two aims of this exercise were the validation of the MULTIBIODOSE protocols by a large number of laboratories and the dissemination of the method with the objective of preparing the basis for a network that could increase Europe's response capacity in the case of a mass casualty radiological emergency. Twelve institutes from eleven European countries and one institute from the USA, with various degrees of expertise in OSL dosimetry, took part in the OSL inter-laboratory comparison. Generally, a good agreement within uncertainties was observed between estimated and nominal doses. - Highlights: • Resistors in mobile phones could function as reliable fortuitous dosimeters in case of a large scale radiological accident. • Two OSL protocols were validated by an inter-laboratory comparison. • It is feasible to set up a network of laboratories so as to increase the measurement capacity

Non-structural Components influencing Hospital Disaster Preparedness in Malaysia

Hospital disaster preparedness refers to measures taken by the hospital’s stakeholders to prepare, reduce the effects of disaster and ensure effective coordination during incident response. Among the measures, non-structural components (i.e., medical laboratory equipment & supplies; architectural; critical lifeline; external; updated building document; and equipment & furnishing) are critical towards hospital disaster preparedness. Nevertheless, over the past few years these components are badly affected due to various types of disasters. Hence, the objective of this paper is to investigate the non-structural components influencing hospital’s disaster preparedness. Cross-sectional survey was conducted among thirty-one (31) Malaysian hospital’s employees. A total of 6 main constructs with 107 non-structural components were analysed and ranked by using SPSS and Relative Importance Index (RII). The results revealed that 6 main constructs (i.e. medical laboratory equipment & supplies; architectural; critical lifeline; external; updated building document; and equipment & furnishing) are rated as ‘very critical’ by the respondents. Among others, availability of medical laboratory equipment and supplies for diagnostic and equipment was ranked first. The results could serve as indicators for the public hospitals to improve its disaster preparedness in terms of planning, organising, knowledge training, equipment, exercising, evaluating and corrective actions through non-structural components.

Full Text Available Este artigo discute um caso de discriminação genética envolvendo uma atleta brasileira de voleibol identificada como portadora do traço falciforme. O traço falciforme é uma das características genéticas mais prevalentes na população brasileira, mas não �� descrito como uma doença genética. O avanço da genética clínica vem provocando uma popularização dos testes genéticos em diferentes contextos de promoção da saúde. Ao criticar o argumento da Confederação Brasileira de Vôlei de que o exame para o traço falciforme seria uma medida de proteção à saúde dos atletas, o objetivo do artigo foi demonstrar como a popularização da informação genética não pode prescindir do aconselhamento genético e de garantias éticas. A análise mostrou que a exclusão da atleta da seleção oficial de vôlei não se justificou por medidas de proteção à saúde, mas por discriminação genética.This paper analyses a case of genetic discrimination of a Brazilian volleyball athlete. A routine exam identified the sickle cell trait in her blood. The sickle cell trait is one of the most prevalent genetic information in Brazilian population, but it not considered a genetic disease. The advancement of clinical genetic promotes a popularization of genetic tests in different health care initiatives. The aims of this paper are: 1 to criticize the argument supporting the test for sickle cell trait as a health care initiative; 2 to demonstrate how the popularization of genetic information demands genetic counseling and ethical protections. The analysis demonstrates how the athlete exclusion from the official volleyball team is not supported by medicine and is a case of genetic discrimination.

This technical note presents the development of a methodological laboratory niche Web site. The "Grossing Technology in Surgical Pathology" (www.grossing-technology.com) Web site is used as an example. Although common steps in creation of most Web sites are followed, there are particular requirements for structuring the template's menu on methodological laboratory Web sites. The "nested doll principle," in which one object is placed inside another, most adequately describes the methodological approach to laboratory Web site design. Fragmentation in presenting the Web site's material highlights the discrete parts of the laboratory procedure. An optimally minimal triad of components can be recommended for the creation of a laboratory niche Web site: a main set of media, a blog, and an ancillary component (host, contact, and links). The inclusion of a blog makes the Web site a dynamic forum for professional communication. By forming links and portals, cloud computing opens opportunities for connecting a niche Web site with other Web sites and professional organizations. As an additional source of information exchange, methodological laboratory niche Web sites are destined to parallel both traditional and new forms, such as books, journals, seminars, webinars, and internal educational materials.

Compliance of Bombardier's Challenger 604 and CRJ200 to FAR25.856(a) : flame propagation of thermal/acoustic insulation materials and future trends in aircraft materials fire safety

Energy Technology Data Exchange (ETDEWEB)

Lewis, W.R. [Bombardier, Montreal, PQ (Canada); Schofield, C.M.A. [Transport Canada, Ottawa, ON (Canada)

2007-07-01

This paper provided details of a testing program designed to ensure the compliance of Bombardier's Challenger 604 to new rules established to improve flammability standards for thermal and acoustic insulation materials. The rule applied to both pressurized and unpressurized sections of the fuselage, as well as to ducting, sound damping foams, and insulation bags. Test samples of all non-metallic insulation components were collected. Testing of the samples was conducted in a chamber with an ignition source as well as a controlled heat flux provided by a radiant panel. The new rules were discussed as well as challenges faced by industry which will have to show compliance for flame propagation requirements. Issues related to the in-service replacement of thermal and acoustic insulation materials were reviewed along with potential changes to flammability regulations. Materials used by Bombardier for compliant constructions were also listed. It was concluded that the safety of airplane occupants will be improved through compliance to new testing methods under harsher fire threat conditions, with more stringent pass and fail criteria. 15 refs., 5 figs.

La formazione di un’aristocrazia: monache e monasteri femminili a Venezia tra IX e XIII secolo

Directory of Open Access Journals (Sweden)

Rapetti, Anna

2014-06-01

Full Text Available This paper examines the processes that shaped the identity of the Venetian aristocracy from the 9th to the 13th centuries and the role played by the relationship between patrician families and some female monasteries. The important female monastery of San Zaccaria and some other nunneries created in the lagoon between the 12th and the 13th centuries are taken into account in the analysis of the formation of Venetian aristocracy from this innovative perspective. By analysing the behaviour of the aristocratic families towards these nunneries, the paper points out how Venetian ruling groups made use of the long-term relationship with nuns as a particularly useful instrument of political competition. The article also shows how some female monasteries were relevant social actors in the process of defi nition of Venetian identity, largely coinciding with their own ruling groups, and in particular with the aristocracy, and with the exercise of power.[it] L’articolo si propone di esaminare il processo di definizione dell’identità del ceto dirigente di Venezia nel periodo IX-XIII secolo e il ruolo occupato dalle relazioni tra le famiglie dell’aristocrazia che costituivano quel ceto e alcuni monasteri femminili. In questa prospettiva, innovativa nell’analisi della formazione dell’aristocrazia di Venezia, si prenderà in esame l’importante monastero femminile di San Zaccaria e si farà inoltre riferimento ad alcuni altri, sorti sulle isole della laguna tra XII e XIII secolo, espressione di un clima religioso e sociale nuovo e particolare. Attraverso l’analisi dei comportamenti adottati dalle famiglie aristocratiche nei confronti di questi monasteri, si dimostra che il ceto dirigente veneziano si servì delle relazioni costanti con le monache come di uno strumento della lotta politica particolarmente utilizzato dalle famiglie dell’aristocrazia della città. Si osserva anche che alcuni monasteri femminili furono a loro volta soggetti attivi

Laboratory information systems (LIS) are critical components of the operation of clinical laboratories. However, the functionalities of LIS have lagged significantly behind the capacities of current hardware and software technologies, while the complexity of the information produced by clinical laboratories has been increasing over time and will soon undergo rapid expansion with the use of new, high-throughput and high-dimensionality laboratory tests. In the broadest sense, LIS are essential to manage the flow of information between health care providers, patients, and laboratories and should be designed to optimize not only laboratory operations but also personalized clinical care. To list suggestions for designing LIS with the goal of optimizing the operation of clinical laboratories while improving clinical care by intelligent management of laboratory information. Literature review, interviews with laboratory users, and personal experience and opinion. Laboratory information systems can improve laboratory operations and improve patient care. Specific suggestions for improving the function of LIS are listed under the following sections: (1) Information Security, (2) Test Ordering, (3) Specimen Collection, Accessioning, and Processing, (4) Analytic Phase, (5) Result Entry and Validation, (6) Result Reporting, (7) Notification Management, (8) Data Mining and Cross-sectional Reports, (9) Method Validation, (10) Quality Management, (11) Administrative and Financial Issues, and (12) Other Operational Issues.

Mineralogical correlation of surficial sediment from area drainages with selected sedimentary interbeds at the Idaho National Engineering Laboratory, Idaho

Energy Technology Data Exchange (ETDEWEB)

Bartholomay, R.C.

1990-08-01

Ongoing research by the US Geological Survey at the INEL involves investigation of the migration of radioactive elements contained in low-level radioactive waste, hydrologic and geologic factors affecting waste movement, and geochemical factors that influence the chemical composition of the waste. Identification of the mineralogy of the Snake River Plain is needed to aid in the study of the hydrology and geochemistry of subsurface waste disposal. The US Geological Surveys project office at the Idaho National Engineering Laboratory, in cooperation with the US Department of Energy, used mineralogical data to correlate surficial sediment samples from the Big Lost River, Little Lost River, and Birch Greek drainages with selected sedimentary interbed core samples taken from test holes at the RWMC (Radioactive Waste Management Complex), TRA (Test Reactors Area), ICPP (Idaho Chemical Processing Plant), and TAN (Test Area North). Correlating the mineralogy of a particular present-day drainage area with a particular sedimentary interbed provides information on historical source of sediment for interbeds in and near the INEL. Mineralogical data indicate that surficial sediment samples from the Big Lost River drainage contained a larger amount of feldspar and pyroxene and a smaller amount of calcite and dolomite than samples from the Little Lost River and Birch Creek drainages. Mineralogical data from sedimentary interbeds at the RWMC, TRA, and ICPP correlate with surficial sediment of the present-day big Lost River drainage. Mineralogical data from a sedimentary interbed at TAN correlate with surficial sediment of the present-day Birch Creek drainage. 13 refs., 5 figs., 3 tabs.

Establishing a temporal bone laboratory: considerations for ENT specialist training.

LENUS (Irish Health Repository)

Fennessy, B G

2012-02-01

Cadaveric temporal bone dissection in a temporal bone laboratory is a vital component in training safe, competent otorhinolaryngologists. Recent controversies pertaining to organ retention have resulted in a more limited supply of temporal bones. Consequently, current trainees are dissecting far fewer bones than their consultants. We discuss the establishment of a temporal bone laboratory in the Department of Anatomy in the University College Cork, from the timely preparation and preservation of the tissue to its disposal. Comparisons are drawn between our experience and that of the United States training schemes. The temporal bone laboratory in Cork is the only one in existence in Ireland. The exposure and experience obtained by registrars rotating through Cork, has resulted in noticeable improvements in their operative abilities. The temporal bone laboratory remains a core component to training. It is hoped that this article may facilitate other units overcoming obstacles to establish a temporal bone laboratory.

Safety precautions for laboratory staff working with meningococci should primarily rely on laboratory procedures preventing exposure to aerosols containing viable meningococci. Despite this, vaccination is a key component of protection in the occupational setting. In the UK in 2009, there were no licensed vaccines for meningococcal capsular group B or conjugate vaccines for capsular groups A, C, W and Y. We therefore undertook a Phase II trial in laboratory workers to investigate the safety and immunogenicity of a four component group B vaccine (4CMenB) and a quadrivalent group A, C, W and Y conjugate vaccine (ACWY-CRM). Enrolment was open to staff aged 18-65 years at the Public Health Laboratory, Manchester who may have had a potential occupational exposure risk to meningococci. 4CMenB was administered at 0, 2 and 6 months in the non-dominant arm and ACWY-CRM concomitantly at 0 months in the dominant arm. Pre- and post-vaccination blood samples were taken and analysed by the serum bactericidal antibody (SBA) assay against A, C, W and Y strains and a panel of seven diverse group B strains. Diary cards were used to record any local and systemic reactions following each vaccination. In total, 38 staff were enrolled and received initial vaccinations with 31 completing the trial per protocol. Both vaccines were proven safe, with local reactogenicity being more commonly reported following 4CMenB than ACWY-CRM. High proportions of subjects had putative protective SBA titres pre-vaccination, with 61-84 and 61-87% protected against A, C, W and Y strains and diverse MenB strains, respectively. Post-vaccination, SBA titres increased with 95-100 and 90-100% of subjects with protective SBA titres against A, C, W and Y strains and diverse MenB strains, respectively. These data suggest that 4CMenB and ACWY-CRM are safe when administered concomitantly and have the potential to enhance protection for laboratory workers. www.clinicaltrials.gov identifier: NCT00962624.

Measurement control is one component of laboratory quality assurance: What are the others

International Nuclear Information System (INIS)

Delvin, W.L.

1986-01-01

The value of a quality assurance program is that the overlooking, ignoring, or downgrading of useful functions and practices will be minimized. The principles of quality assurance make a great tool for minimizing problems and for helping to find and correct deficiencies and problems when they occur. Finding and correcting deficiencies and problems while they are still small - before they become monsters - will certainly make life easier in the operation of a laboratory. This takes diligence in being aware of what is going on in the laboratory and firm resolve by management to take effective corrective actions when necessary. It takes more than applying band aids to problems. 4 refs

Identification of a transformer homolog in the acorn worm, Saccoglossus kowalevskii, and analysis of its activity in insect cells.

The transformer (tra) gene is an intermediate component of the sex determination hierarchy in many insect species. The homolog of tra is also found in two branchiopod crustacean species but is not known outside arthropods. We have isolated a tra homolog in the acorn worm, Saccoglossus kowalevskii, which is a hemichordate belonging to the deuterostome superphylum. The full-length complementary DNA (cDNA) of the S. kowalevskii tra homolog (Sktra) has a 3786-bp open reading frame that encodes a 1261-amino acid sequence including a TRA-CAM domain and an arginine/serine (RS)-rich domain, both of which are characteristic of TRA orthologs. Reverse transcription PCR (RT-PCR) analyses demonstrated that Sktra showed no differences in expression patterns between testes and ovaries, but its expression level was approximately 7.5-fold higher in the testes than in the ovaries. TRA, together with the protein product of the transformer-2 (tra-2) gene, assembles on doublesex (dsx) pre-messenger RNA (mRNA) via the cis-regulatory element, enhancing female-specific splicing of dsx in Drosophila. To understand functional conservation of the SkTRA protein as a dsx-splicing activator, we investigated whether SkTRA is capable of inducing female-specific splicing of the Drosophila dsx. Ectopic expression of Sktra cDNA in insect cultured cells did not induce the female-specific splicing of dsx. On the other hand, forced expression of Sktra-2 (a tra-2 homolog of S. kowalevskii) was able to induce the female-specific dsx splicing. These results demonstrate that the function as a dsx-splicing activator is not conserved in SkTRA even though SkTRA-2 is capable of functionally replacing the Drosophila TRA-2. We have also found a tra homolog in an echinoderm genome. This study provides the first evidence that that tra is conserved not only in arthropods but also in basal species of deuterostoms.

ão respondem a tratamentos de primeira linha. Não obstante, não existem estudos comparando diretamente traços de personalidade entre pacientes responsivos e refratários ao tratamento do transtorno obsessivo-compulsivo. Este estudo investiga diferenças nos traços da personalidade baseados no Inventário de Temperamento e Caráter de Cloninger (TCI entre dois grupos de pacientes com transtorno obsessivo-compulsivo classificados segundo desfecho terapêutico: responsivos e refratários. MÉTODO: Quarenta e cinco pacientes refratários e 44 responsivos foram selecionados. Os indivíduos foram considerados responsivos se, após tratamento com terapêutica convencional, apresentaram diminuição de ao menos 40% no escore inicial da Yale-Brown Obsessive Compulsive Scale, foram classificados como "melhor" ou "muito melhor" na Clinical Global Impressions; e mantiveram melhora por pelo menos um ano. Os refratários eram os pacientes que não atingiram redução de ao menos 25% na Yale-Brown Obsessive Compulsive Scale e tiveram a melhoria menor que "mínima" na Clinical Global Impressions após o tratamento com ao menos três inibidores seletivos da recaptura de serotonina, incluindo clomipramina, e ao menos 20 horas da terapia cognitiva-comportamental. Os traços da personalidade foram avaliados através do Temperament and Character Inventory. RESULTADOS: Refratários pontuaram menos em autodirecionamento e tenderam a pontuar mais em persistência. CONCLUSÃO: Este estudo sugere que os traços de personalidade, especialmente autodirecionamento, estão associados com a resposta pobre do tratamento em pacientes com transtorno obsessivo-compulsivo.

Low Energy Accelerator Laboratory Technical Area 53, Los Alamos National Laboratory. Environmental assessment

International Nuclear Information System (INIS)

1995-04-01

This Environmental Assessment (EA) analyzes the potential environmental impacts that would be expected to occur if the Department of Energy (DOE) were to construct and operate a small research and development laboratory building at Technical Area (TA) 53 at the Los Alamos National Laboratory (LANL), Los Alamos, New Mexico. DOE proposes to construct a small building to be called the Low Energy Accelerator Laboratory (LEAL), at a previously cleared, bladed, and leveled quarter-acre site next to other facilities housing linear accelerator research activities at TA-53. Operations proposed for LEAL would consist of bench-scale research, development, and testing of the initial section of linear particle accelerators. This initial section consists of various components that are collectively called an injector system. The anticipated life span of the proposed development program would be about 15 years

Sodium removal from Hallam Reactor components

Huntsman, L.K.; Meservey, R.H.

1979-08-01

This report discussed the removal of sodium from major components of the Hallam Nuclear Power Facility. This facility contained the experimental ractor used to test the feasibility of sodium coolant. The Idaho Operations Office of the Department of Energy assigned EG and G Idaho, Inc., the task of carrying out this decontamination and decommissioning program at the Idaho National Engineering Laboratory (INEL). Since their shipment to the INEL from Lincoln, Nebraska in 1968, the Hallam Reactor components had been stored in inert nitrogen to prevent the sodium in the components from reacting with moisture in the air. The procedure used to react the sodium in the components and to decontaminate them is discussed. Problems and unusual occurrences in the decontamination and decommissioning process are also reported

A comparative test of the theory of reasoned action and the theory of planned behavior in the prediction of condom use intentions in a national sample of English young people.

Science.gov (United States)

Sutton, S; McVey, D; Glanz, A

1999-01-01

Based on the theories of reasoned action (TRA) and planned behavior (TPB), predictors of condom use intentions were investigated in 949 young people (16-24 years of age) from a national survey conducted in England. Contrary to expectations, the TPB did not perform significantly better than the TRA, even among women. Measures of past behavior were the best predictors of intentions and attenuated the effects of attitude and subjective norm. There was only weak evidence for the multiplicative assumption underlying the TRA and TPB. Although the TRA components were not the strongest predictors, the beliefs on which they are based are potentially amenable to change through information-based intervention programs. A number of practical suggestions for developing intervention strategies are offered.

In this contribution, the most interesting and educational failure cases are presented that the author came across during his over twenty years of laboratory practice as manager of the Materials Testing Laboratory of the Berlin Gas Turbine Plant of Siemens' Power and Gas Division. The case studies are presented and categorised in accordance with VDI Guideline 3822, the German failure analyst's guide to the subject of how to organise and run a root cause failure analysis. An effort was made to have each of the main four categories of failure causes represented, namely failures due to mechanical loading, corrosive failures, failures due to thermal loading, and tribological failures. Case studies include turbomachinery components that failed due to tensile overload, stress corrosion cracking, intergranular corrosion, hydrogen embrittlement, hot cracking, fretting, erosion, and galling. Affected components include valves, retaining rings, tubing and piping, burners, rotor disks, lifting lugs, and casings. Some of the presented cases were published in the new section ''Failure Analysis'' of Practical Metallography between October 2011 and the present time. Others were oral presentations at the Metallography conferences and at the annual failure analysis conferences ''VDI Jahrestagung Schadensanalyse'', held during that time. The focus of discussion of the failure cases in this paper is the metallurgical evaluation of failure causes. This is the approach taken in many small and industrial laboratories. A holistic approach of a failure case, which includes calculation and simulation methods such as finite element analysis, and which also implies a knowledge of the service stresses intended by design as well as the actual loading situation of the failed part, is not the aim of this contribution.

Análise da influência do traço nas propriedades do compósito cimento-madeira

Full Text Available Os compósitos de cimento com adição de madeira apresentam vantagens, quando comparados a outros materiais convencionais da construção civil, como resistência à água, ao fogo e aos agentes deterioradores. Um dos obstáculos para o uso desse compósito é a inibição causada pela madeira na cura do cimento, devido aos componentes da madeira afetarem as reações, tendo como consequência um compósito de baixa qualidade. Dessa forma, este trabalho teve por objetivo avaliar diferentes traços do compósito cimento-madeira, utilizando resíduos de Pinus spp., por meio de ensaios de laboratório. Foi utilizado o cimento Portland CP II Z 32, relação água/cimento igual a 0,4; o aditivo químico escolhido foi o cloreto de cálcio para acelerar a pega. Para a comparação de desempenho, foram delimitadas quatro dosagens diferentes, com teores de adição de madeira de 10%, 20%, 25% e 33% em relação à massa de cimento. Para a análise, foram feitos ensaios das propriedades físicas e mecânicas para todas as dosagens, sendo, posteriormente, submetidas à análise da variância e teste de Tukey. Os resultados dos ensaios das propriedades físicas e mecânicas dos compósitos demonstraram que, para as relações escolhidas, quanto menor for a adição de madeira melhores serão os resultados das propriedades, mas mesmo os traços com maiores teores de madeira apresentam resultados relevantes, atentando-se apenas para o fato da relação água/cimento ser baixa para os casos analisados, e, devido a isso, ter influenciado negativamente nos resultados.

The health of the christifidelis celiac between diet gluten free and invalidity of the hosts quibus glutinum ablatum est.  ABSTRACT: The communion of celiac has aroused the attention of the Congregation for the Doctrine of the Faith for the direct connection between gluten, cause of the disease, and bread mere triticeus, precious element of the Eucharist. The complex matter concerns the impelling urgency to allow the christifidelis celiac to follow a super stricte gluten free diet, necessary way to the protection of his mental and physical health, without expelling him from the eucharistic banquet, indispensable instrument of salvation of his own soul. Therefore, in the saving mission of the Church called to the salus animarum of every man, without discriminating exclusions, direct specific norms are emanated to harmonize the dogmatic demands, connected to the Eucharestic, and the therapeutic needs related to mental and physical health of the faithful with the disease. Such norms have faced the validity of the eucharistic matter sealing the invalidity of the hosts quibus glutinum ablatum est, with a meaningful evolution, during the time. It stays, nevertheless, the suspect of an exhaustive solution of the question

Il territorio delle Lipari tra ambiente, cinema e turismo / The territory of Lipari between environment, cinema and tourism

Elena Di Blasi

2016-05-01

Full Text Available Fino agli anni ’50 le Lipari (dette anche Eolie, sfavorite dall’insularità e con un’economia di sussistenza, basata su attività tradizionali, erano dominate da povertà ed emigrazione. Tutto mutò nel 1949, quando una troupe cinematografica, guidata da Rossellini, girò Stromboli, interpretato da Ingrid Bergman: tra i due era nata una storia d’amore. Poco dopo, un’altra troupe utilizzò Vulcano come location dell’omonimo film, con Anna Magnani, ex fiamma di Rossellini. Questi cult passarono alla storia del cinema come la guerra dei vulcani. I due film, con gli scoop legati alle vicende sentimentali dei protagonisti, hanno innescato un nuovo percorso per le Eolie, fuori dall’atavico letargo, che ha determinato un vero e proprio “boom turistico”. Indagando la variegata realtà delle Lipari, lo scopo del presente articolo è quello di dimostrare come, attraverso un’analisi storica del mercato turistico, l’arrivo del cinema nel territorio eoliano abbia innescato importanti processi di sviluppo economico e cambiamento sociale. Questa ricerca vuole, inoltre, evidenziare il rapporto privilegiato tra insularità e cineturismo. Till the late 50s the Aeolian Islands, plagued by insularity and characterized by a subsistence economy based on traditional activities, had been dominated by poverty and emigration. All changed in 1949 when Rossellini shot Stromboli featuring Ingrid Bergman, his new love. Soon after a crew shot in Volcano the homonymous film starring Anna Magnani, Rossellini’s old flame. The two films, gone down in history as the war of volcanoes, and the scoops about the love scandal have drawn a new path for the Aeolian Islands that has taken them to a tourist boom. The present paper aims to show by means of a historical analysis of the local tourist market how the coming of the film industry have triggered processes of economic growth and social change in the Aeolian Islands. This paper also aims to point out the

Optical CDMA components requirements

Optical CDMA is a complementary multiple access technology to WDMA. Optical CDMA potentially provides a large number of virtual optical channels for IXC, LEC and CLEC or supports a large number of high-speed users in LAN. In a network, it provides asynchronous, multi-rate, multi-user communication with network scalability, re-configurability (bandwidth on demand), and network security (provided by inherent CDMA coding). However, optical CDMA technology is less mature in comparison to WDMA. The components requirements are also different from WDMA. We have demonstrated a video transport/switching system over a distance of 40 Km using discrete optical components in our laboratory. We are currently pursuing PIC implementation. In this paper, we will describe the optical CDMA concept/features, the demonstration system, and the requirements of some critical optical components such as broadband optical source, broadband optical amplifier, spectral spreading/de- spreading, and fixed/programmable mask.

This document reports the results of laboratory radionuclide measurements on a representative group of non-fuel assembly (NFA) components for the purposes of waste classification. This document also provides a methodology to estimate the radionuclide inventory of NFA components, including those located outside the fueled region of a nuclear reactor. These radionuclide estimates can then be used to determine the waste classification of NFA components for which there are no physical measurements. Previously, few radionuclide inventory measurements had been performed on NFA components. For this project, recommended scaling factors were selected for the ORIGEN2 computer code that result in conservative estimates of radionuclide concentrations in NFA components. These scaling factors were based upon experimental data obtained from the following NFA components: (1) a pressurized water reactor (PWR) burnable poison rod assembly, (2) a PVM rod cluster control assembly, and (3) a boiling water reactor cruciform control rod blade. As a whole, these components were found to be within Class C limits. Laboratory radionuclide measurements for these components are provided in detail

Corlett, J.N.; Rimmer, R.A.

1993-05-01

The high current and short bunch length of the ALS beam make the machine susceptible to beam instabilities over a frequency range extending to 13 GHz and beyond. All components of the storage ring have been carefully designed to minimize the impedance presented to the beam, and assemblies have been laid out to avoid resonant enclosures between components. Novel bellows shields allowing considerable mechanical movement while maintaining a low impedance are described. Results are presented of impedance measurements of ALS components and assemblies of components, using a precision coaxial wire technique in frequency domain, extending to frequencies beyond cut-off. All measurements were performed at the Lambertson Beam Electrodynamics Laboratory of the Center for Beam Physics at LBL

2012-01-01

The aim of this study was to prepare, pilot and validate a questionnaire to evaluate patient safety in the specific context of clinical laboratories. A specific questionnaire on patient safety in the laboratory, with 62 items grouped into six areas, was developed, taking into consideration the diverse human and laboratory contextual factors which may contribute to producing errors. A pilot study of 30 interviews was carried out, including validity and reliability analyses using principal components factor analysis and Cronbach's alpha. Subsequently, 240 questionnaires were sent to 21 hospitals, followed by a test-retest of 41 questionnaires with the definitive version. The sample analyzed was composed of 225 questionnaires (an overall response rate of 80%). Of the 62 items initially assessed, 17 were eliminated due to non-compliance with the criteria established before the principal components factor analysis was performed. For the 45 remaining items, 12 components were identified, with an cumulative variance of 69.5%. In seven of the 10 components with two or more items, Cronbach's alpha was higher than 0.7. The questionnaire items assessed in the test-retest were found to be stable. We present the first questionnaire with sufficiently proven validity and reliability for evaluating patient safety in the specific context of clinical laboratories. This questionnaire provides a useful instrument to perform a subsequent macrostudy of hospital clinical laboratories in Spain. The questionnaire can also be used to monitor and promote commitment to patient safety within the search for continuous quality improvement. Copyright © 2011 SESPAS. Published by Elsevier Espana.

Tests of an environmental and personnel safe cleaning process for Brookhaven National Laboratory accelerator and storage ring components

Foerster, C.L.; Lanni, C.; Lee, R.; Mitchell, G.; Quade, W.

1997-01-01

A large measure of the successful operation of the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory (BNL) for over a decade can be attributed to the cleaning of its ultrahigh vacuum (UHV) components during and after construction. A new UHV cleaning process, which has to be environmentally and personnel safe, is needed to replace the harsh, unfriendly process which is still in use. Dow Advanced Cleaning Systems was contracted to develop a replacement process without the use of harsh chemicals and which must clean vacuum surfaces as well as the existing process. Acceptance of the replacement process was primarily based on photon stimulated desorption (PSD) measurements of beam tube samples run on NSLS beam line U10B. One meter long beam tube samples were fabricated from aluminum, 304 stainless steel, and oxygen-free copper. Initially, coupon samples were cleaned and passed preliminary testing for the proposed process. Next, beam tube samples of each material were cleaned, and the PSD measured on beam line U10B using white light with a critical energy of 487 eV. Prior to cleaning, the samples were contaminated with a mixture of cutting oils, lubricants, vacuum oils, and vacuum grease. The contaminated samples were then baked. Samples of each material were also cleaned with the existing process after the same preparation. Beam tube samples were exposed to between 10 22 and 10 23 photons per meter for a PSD measurement. Desorption yields for H 2 , CO, CO 2 , CH 4 , and H 2 O are reported for both the existing cleaning and for the replacement cleaning process. Preliminary data, residual gas scans, and PSD results are given and discussed. The new process is also compared with new cleaning methods developed in other laboratories. After modification, the new UHV cleaning process was accepted by BNL

Full Text Available No Brasil, o ensaio laboratorial de compactação Proctor é normatizado pela Associação Brasileira de Normas Técnicas (NBR 7182/1986 e pelo Departamento Nacional de Infraestrutura e Transportes (DNIT – ME 164/2013 e DNIT – ME 162/1994. As normas apresentam diferentes alternativas para executar a compactação Proctor, no entanto, verifica-se que o comportamento mecânico de um solo compactado é função do índice de vazios, do grau de saturação e principalmente da estrutura do solo que é diretamente influenciada pelo processo de compactação adotado. Este trabalho teve como objetivo comparar quatro processos distintos de compactação (mecânica com reúso, manual com reúso, manual sem reúso e manual sem reúso com umedecimento da amostra 24 horas antes da compactação, utilizando a energia intermediária, com a pretensão de avaliar os seus efeitos nas propriedades de resistência à compressão, resistência à tração e resiliência de um solo. A fase experimental foi dividida em três (3 etapas: ensaios de caracterização do solo, ensaios de compactação Proctor e ensaios mecânicos (Resistência à Compressão Simples - RCS, Resistência à Tração por Compressão Diametral - RT e Módulo de Resiliência - MR. Por meio dessa pesquisa, constatou-se que o tipo de compactação utilizado exerceu uma influência significativa nos resultados, pois de um modo geral os valores de RT , RCS e MR obtidos na compactação manual sem reúso 24h foram superiores as demais compactações.

The high temperature engineering test reactor (HTTR) with the target operation temperature of 950degC established the first criticality on November, 1998 based on a large amount of R and D results on fuel and materials. In such R and D works, the development of reactor materials are one of the key issues from the view point of reactor environments such as extremely high temperature, neutron irradiation and so on for the HTTR. The Research Hot Laboratory (RHL) had carried out much kind of post irradiation examinations (PIEs) on core component and pressure vessel materials for during more than a quarter century. And obtained data played an important role in development, characterization and licensing of those materials for the HTTR. This paper describes the PIE technology developed at RHL and typical results on mechanical tests such as elevated temperature tensile and creep rupture tests for Hasteloy-X, Incolloy 800H and so on, and Charpy impact, J IC fracture toughness, K Id fracture toughness and small punch tests for normalized and tempered 2 1/4Cr-1Mo steel from historical view. In addition, an electrochemical test technique established for investigating the irradiation embrittlement mechanism on 2 1/4Cr-1Mo steel is also mentioned. (author)

Apesar dessa diversidade, esses fatores confluem para cinco traços amplos que estão em um mesmo nível de hierarquia. O presente estudo apresenta uma hipótese alternativa, postulando níveis entre os traços amplos do modelo. Fizeram parte do estudo 684 estudantes do ensino fundamental e médio de uma escola particular de Belo Horizonte, MG, com idades entre 10 e 18 anos (m = 13,71 e DP= 2,11. Para medir os fatores do Big Five foi utilizado o Inventário de Características de Personalidade, anteriormente chamado de Inventário dos Adjetivos de Personalidade, de Pinheiro, Gomes e Braga (2009. O instrumento mensura oito polaridades das 10 polaridades presentes nos cinco traços amplos do Big Five. Dois modelos foram comparados via método path analysis: um modelo de quatro níveis hierárquicos e um modelo não hierárquico.

1989-11-01

To demonstrate how ''high-level'' qualification test data can be used to estimate the ultimate seismic capacity of nuclear power plant equipment, we assessed in detail various electrical components tested by the Pacific Gas ampersand Electric Company for its Diablo Canyon plant. As part of our Phase I Component Fragility Research Program, we evaluated seismic fragility for five Diablo Canyon components: medium-voltage (4kV) switchgear; safeguard relay board; emergency light battery pack; potential transformer; and station battery and racks. This report discusses our Phase II fragility evaluation of a single Westinghouse Type W motor control center column, a fan cooler motor controller, and three local starters at the Diablo Canyon nuclear power plant. These components were seismically qualified by means of biaxial random motion tests on a shaker table, and the test response spectra formed the basis for the estimate of the seismic capacity of the components. The seismic capacity of each component is referenced to the zero period acceleration (ZPA) and, in our Phase II study only, to the average spectral acceleration (ASA) of the motion at its base. For the motor control center, the seismic capacity was compared to the capacity of a Westinghouse Five-Star MCC subjected to actual fragility tests by LLNL during the Phase I Component Fragility Research Program, and to generic capacities developed by the Brookhaven National Laboratory for motor control center. Except for the medium-voltage switchgear, all of the components considered in both our Phase I and Phase II evaluations were qualified in their standard commercial configurations or with only relatively minor modifications such as top bracing of cabinets. 8 refs., 67 figs., 7 tabs

1994-07-01

This Process Waste Assessment was conducted to evaluate the Radiography Laboratory, located in Building 923. It documents the processes, identifies the hazardous chemical waste streams generated by these processes, recommends possible ways to minimize waste, and serves as a reference for future assessments of this facility. The Radiography Laboratory provides film radiography or radioscopy (electronic imaging) of weapon and nonweapon components. The Radiography Laboratory has six x-ray machines and one gamma ray source. It also has several other sealed beta- and gamma-ray isotope sources of low microcurie (μCi) activity. The photochemical processes generate most of the Radiography Laboratory's routinely generated hazardous waste, and most of that is generated by the DuPont film processor. Because the DuPont film processor generates the most photochemical waste, it was selected for an estimated material balance

Full Text Available Proper selection of the luting agent is fundamental to avoid failure due to lack of retention in post-retained crowns. The objective of this study was to investigate the tensile bond strength and failure mode of glass fiber posts luted with different cements. Glass fiber posts were luted in 40 mandibular premolars, divided into 4 groups (n = 10: Group 1 - resin-modified glass ionomer RelyX Luting; Group 2 - resin-modified glass ionomer Fuji Plus; Group 3 - resin cement RelyX ARC; Group 4 - resin cement Enforce. Specimens were assessed by tensile strength testing and light microscopy analysis for observation of failure mode. The tensile bond strength values of each group were compared by ANOVA and Tukey test. The significance level was set at 5%. The failure modes were described as percentages. The following tensile strength values were obtained: Group 1 - 247.6 N; Group 2 - 256.7 N; Group 3 - 502.1 N; Group 4 - 477.3 N. There was no statistically significant difference between Groups 1 and 2 or between Groups 3 and 4, yet the resin cements presented significantly higher tensile bond strength values than those presented by the glass ionomer cements. Group 1 displayed 70% of cohesive failures, whereas Groups 2, 3 and 4 exhibited 70% to 80% of adhesive failures at the dentin-cement interface. We concluded that resin cements and glass ionomer cements are able to provide clinically sufficient retention of glass fiber posts, and that glass ionomer cements may be especially indicated when the application of adhesive techniques is difficult.A seleção adequada do agente cimentante é essencial para evitar falhas por perda de retenção em coroas retidas por núcleos.

Full Text Available Riassunto: Il riutilizzo dei nuraghi in epoca romana appare un fenomeno numericamente rilevante e caratteristico delle dinamiche di occupazione delle aree rurali della Sardegna, che risulta ancora di difficile inquadramento. Sono attestate, infatti, diverse finalità di riutilizzo ma non è stato finora possibile tracciare un quadro ipotetico delle modalità e delle finalità complessive di tale riuso, che viene tradizionalmente legato a una continuità di frequentazione di comunità locali e a un processo di acculturazione e romanizzazione più o meno profonda degli etnici indigeni. Nel presente contributo si presentano i dati relativi alle attestazioni di riutilizzo in un’area compresa tra Marmilla e Sarcidano, particolarmente importante per la sua collocazione geografica e strategica, nella quale si evidenzia un interessante quadro diacronico delle dinamiche di riutilizzo e della loro matrice culturale. Abstract: Reuse of nuraghi in Roman age appears as a numerically significant phenomenon and  a characteristic of settlement dynamics in Sardinian rural areas, but  still difficult to classify. Different purposes of reuse are known but has not yet been possible to draw a picture of the mode of operation and of the objectives of such re-use, which is traditionally linked to a continuity of  use related to local communities and to a process of acculturation and Romanization of indigenous ethnic groups. In this paper we present the reuse exemples of an area between Marmilla and Sarcidano, particularly important for its geographical and strategic position, in which is possible to highlight an interesting diachronic picture of reuse dynamics and of the cultural matrix of the phenomenon.

Development of quality measurement principles is a strategic point for each clinical laboratory. Preexamination process is the most critical and the most difficult to be managed. The aim of this study is to identify, quantify, and monitor the nonconformities of the pre-analytical process using quality indicators that can affect the patient's health safety in four different locations of a Romanian private clinical laboratory. The study group consisted of all the analysis requests received by the departments of biochemistry, hematology, and coagulation from January through March 2015. In order to collect the pre-analytical nonconformities, we created a "Risk Budget", using the entries from the "Evidence notebook--non-conform samples" from the above mentioned departments. The laboratory established the quality indicators by means of the risk management technique in order to identify and control the sources of errors, FMEA (Failure Modes and Effects Analyses), which had been implemented and monitored for its purposes and special needs. For the assessment of the control level over the processes, the results were transformed on the Six Sigma scale, using the Westgard calculation method and being obtained in this way the frequency with which an error may occur. (https://www.westgard. com/six-sigma-calculators.htm). The obtained results prove that the quantification and monitoring of the indicators can be a control instrument for the pre-analytic activities. The calculation of the Six Sigma value adds extra information to the study because it allows the detection of the processes which need improvement (Sigma value higher than 4 represents a well controlled process). The highest rates were observed for the hemolyzed and the lipemic samples, in the department of biochemistry and hemolyzed, insufficient sample volume, or clotted samples for the department of hematology and coagulation. Significant statistical differences between laboratories participating in the study have

Seasonally occurring populations of barn swallows nest near the Test Reactor Area (TRA) radioactive leaching ponds on the Idaho National Engineering Laboratory (INEL) Site. These birds utilize leaching pond arthropods and are therefore capable of accumulating radioactive materials and exporting them from the INEL Site during migration. The breeding biology is discussed for these swallows and a control group located 100 km away. Total nestling mortality for the controls and a 1977 TRA population was found to be statistically identical. Over 20 fission and activation products have been detected in immature and adult TRA birds. Mean concentrations of detectable radionuclides were used to calculate internal dose rates, and results showed that Na-24 contributed about 72% of the total average of 21.9 mrad/d for adult birds. Concentration factors were also calculated for predominant radionuclides in swallows relative to filtered pond water. Data from LiF dosimeters in swallow nests constructed with contaminated mud indicated average dose rates were 84 mrad/d for eggs and 220 mrad/d for nestlings. Growth curves were constructed for the immature TRA birds and controls. The first clutch of TRA swallows was found to have a significantly lower mean growth rate constant than the first clutch of controls. The statistical difference in growth rate between the control and TRA first clutch populations may have resulted from differences in climate, nesting site habitat, or available food sources, and cannot be solely attributed to radiation exposure as a causative factor. Growth rate parameters for TRA birds were within the range of values reported in the literature

Fine particles (PM(2.5)) are an important component of air pollution. Epidemiological studies have shown health effects due to ambient air particles, particularly allergies in children. Since the main difficulty is to determine exposure to such pollution, traffic air pollutant (TAP) dispersions models have been developed to improve the estimation of individual exposure levels. One such model, the ExTra index, has been validated for nitrogen oxide concentrations but not for other pollutants. The purpose of this study was to assess the validity of the ExTra index to assess PM(2.5) exposure. We compared PM(2.5) concentrations calculated by the ExTra index to reference measures (passive samplers situated under the covered part of the playground), in 15 schools in Bordeaux, in 2000. First, we collected the input data required by the ExTra index: background and local pollution depending on traffic, meteorology and topography. Second, the ExTra index was calculated for each school. Statistical analysis consisted of a graphic description; then, we calculated an intraclass correlation coefficient. Concentrations calculated with the ExTra index and the reference method were similar. The ExTra index underestimated exposure by 2.2 microg m(-3) on average compared to the reference method. The intraclass correlation coefficient was 0.85 and its 95% confidence interval was [0.62; 0.95]. The results suggest that the ExTra index provides an assessment of PM(2.5) exposure similar to that of the reference method. Although caution is required in interpreting these results owing to the small number of sites, the ExTra index could be a useful epidemiological tool for reconstructing individual exposure, an important challenge in epidemiology.

ELAN - expert system supported information and management system for analytical laboratories

International Nuclear Information System (INIS)

Jaeschke, A.; Orth, H.; Zilly, G.

1990-08-01

The demand for high efficiency and short response time calls for the use of computer support in chemico-analytical laboratories. This is usually achieved by laboratory information and management systems covering the three levels of analytical instrument automation, laboratory operation support and laboratory management. The management component of the systems implemented up to now suffers from a lack of flexibility as far as unforeseen analytical investigations outside the laboratory routine work are concerned. Another drawback is the lack of adaptability with respect to structural changes in laboratory organization. It can be eliminated by the application of expert system structures and methods for the implementation of this system level. The ELAN laboratory information and management system has been developed on the basis of this concept. (orig.) [de

Oligoβ-glucan and oligochitosan were prepared by gamma Co-60 irradiation of β-glucan/H_2O_2 and chitosan/H_2O_2 solution. The efficiency of the degradation process was determined by gel permeation chromatography (GPC) method. Results showed that the Mw decreased with increasing concentration of H_2O_2 and doses. For oligoβ-glucan, Mw reduced from 56.7 kDa to 7.1 kDa when β-glucan 10%/H_2O_2 1% solution was irradiated at 14 kGy. For oligochitosan, Mw reduced from 45.5 kDa to 5.0 kDa when chitosan 5%/H_2O_2 0.5% solution was irradiated at 21 kGy. Tra catfish (Pangasianodon hypophthalmus) was fed with oligoβ-glucan and oligochitosan in various concentrations of 0, 50, 100, and 200 mg/kg feed for 45 days and then was challenged with Edwardsiella ictaluri bacteria to investigate immune stimulation effect against white patches in the internal organs disease. The results indicated that oligoβ-glucan and oligochitosan exhibited good immune stimulation effect with optimum concentration of 100 mg/kg feed. Survival rate of Tra catfishes fed with oligochitosan and oligoβ-glucan is 47.62 ± 1.96% and 46.67 ± 2.58%, respectively. In addition, the mixture of oligochitosan 50 mg/kg + oligo?-glucan 50 mg/kg showed the highest survival rate (62.22 ± 1.96%). (author)

Transversus abdominis is part of a global not local muscle synergy during arm movement.

Science.gov (United States)

Morris, S L; Lay, B; Allison, G T

2013-10-01

The trunk muscle transversus abdominis (TrA) is thought to be controlled independently of the global trunk muscles. Methodological issues in the 1990s research such as unilateral electromyography and a limited range of arm movements justify a re-examination of this theory. The hypothesis tested is that TrA bilateral co-contraction is a typical muscle synergy during arm movement. The activity of 6 pairs of trunk and lower limb muscles was recorded using bilateral electromyography during anticipatory postural adjustments (APAs) associated with the arm movements. The integrated APA electromyographical signals were analyzed for muscle synergy using Principle Component Analysis. TrA does not typically bilaterally co-contract during arm movements (1 out of 6 participants did). APA muscle activity of all muscles during asymmetrical arm movements typically reflected a direction specific diagonal pattern incorporating a twisting motion to transfer energy from the ground up. This finding is not consistent with the hypothesis that TrA plays a unique role providing bilateral, feedforward, multidirectional stiffening of the spine. This has significant implications to the theories underlying the role of TrA in back pain and in the training of isolated bilateral co-contraction of TrA in the prophylaxis of back pain.

1994-03-01

On December 30, 1990, the US Department of Energy entered into a contract with General Atomics (GA) to be the Inertial Confinement Fusion Target Component Fabrication and Technology Development Support contractor. This report documents the technical activities which took place under this contract during the period of October 1, 1992 through September 30, 1993. During this period, GA was assigned 18 tasks in support of the Inertial Confinement Fusion program and its laboratories. These tasks included ''Capabilities Activation'' and ''Capabilities Demonstration'' to enable us to begin production of glass and composite polymer capsules. Capsule delivery tasks included ''Small Glass Shell Deliveries'' and ''Composite Polymer Capsules'' for Lawrence Livermore National Laboratory (LLNL) and Los Alamos National Laboratory (LANL). We also were asked to provide direct ''Onsite Support'' at LLNL and LANL. We continued planning for the transfer of ''Micromachining Equipment from Rocky Flats'' and established ''Target Component Micromachining and Electroplating Facilities'' at GA. We fabricated over 1100 films and filters of 11 types for Sandia National Laboratory and provided full-time onsite engineering support for target fabrication and characterization. We initiated development of methods to make targets for the Naval Research Laboratory. We investigated spherical interferometry, built an automated capsule sorter, and developed an apparatus for calorimetric measurement of fuel fill for LLNL. We assisted LANL in the ''Characterization of Opaque b-Layered Targets.'' We developed deuterated and UV-opaque polymers for use by the University of Rochester's Laboratory for Laser Energetics (UR/LLE) and devised a triple-orifice droplet generator to demonstrate the controlled-mass nature of the microencapsulation process

Leaching of wood ash - Laboratory and field studies; Lakning av vedaska - Laboratorie- och faeltstudier

Energy Technology Data Exchange (ETDEWEB)

Larsson, Per-Erik

2012-02-15

High forest production leads to diminishing amounts of base cations and micro nutrients in forest soils. This is due to uptake in, and harvest of, the trees. Losses can be compensated for by spreading stabilized wood ash on the forest ground, which means recycling of base cations and micro nutrients. Chemical composition of wood ash can easily be described by standard methods in the laboratory. However, this does not include the process of leaching in nature, such as which components and leaching rate for different compounds. During field conditions several factors are added, which are not available in the laboratory. After almost 10 years in the forest soils there still remains large quantities of the original product. Only 10-30 % of the wood ash products and 5 % of the lime product has been leached. In the laboratory study the leached amount was slightly larger, at the most 35 % for wood ash and 20 % for lime. Both studies indicate long time for weathering of the products in forest soils. Slower leaching rate from pellets of wood ash compared to leaching rate from crushed wood ash in the laboratory study is not verified by the field study. This indicates limited possibilities to control rates of leaching in the environment

An elementary components of variance analysis for multi-centre quality control

International Nuclear Information System (INIS)

Munson, P.J.; Rodbard, D.

1978-01-01

The serious variability of RIA results from different laboratories indicates the need for multi-laboratory collaborative quality-control (QC) studies. Simple graphical display of data in the form of histograms is useful but insufficient. The paper discusses statistical analysis methods for such studies using an ''analysis of variance with components of variance estimation''. This technique allocates the total variance into components corresponding to between-laboratory, between-assay, and residual or within-assay variability. Problems with RIA data, e.g. severe non-uniformity of variance and/or departure from a normal distribution violate some of the usual assumptions underlying analysis of variance. In order to correct these problems, it is often necessary to transform the data before analysis by using a logarithmic, square-root, percentile, ranking, RIDIT, ''Studentizing'' or other transformation. Ametric transformations such as ranks or percentiles protect against the undue influence of outlying observations, but discard much intrinsic information. Several possible relationships of standard deviation to the laboratory mean are considered. Each relationship corresponds to an underlying statistical model and an appropriate analysis technique. Tests for homogeneity of variance may be used to determine whether an appropriate model has been chosen, although the exact functional relationship of standard deviation to laboratory mean may be difficult to establish. Appropriate graphical display aids visual understanding of the data. A plot of the ranked standard deviation versus ranked laboratory mean is a convenient way to summarize a QC study. This plot also allows determination of the rank correlation, which indicates a net relationship of variance to laboratory mean

CHNTRN: a CHaNnel TRaNsport model for simulating sediment and chemical distribution in a stream/river network

Energy Technology Data Exchange (ETDEWEB)

Yeh, G.T.

1983-09-01

This report presents the development of a CHaNnel TRaNsport model for simulating sediment and chemical distribution in a stream/river network. A particular feature of the model is its capability to deal with the network system that may consist of any number of joined and branched streams/rivers of comparable size. The model employs a numerical method - an integrated compartment method (ICM) - which greatly facilitates the setup of the matrix equation for the discrete field approximating the corresponding continuous field. Most of the possible boundary conditions that may be anticipated in real-world problems are considered. These include junctions, prescribed concentration, prescribed dispersive flux, and prescribed total flux. The model is applied to two case studies: (1) a single river and (2) a five-segment river in a watershed. Results indicate that the model can realistically simulate the behavior of the sediment and chemical variations in a stream/river network. 11 references, 10 figures, 3 tables.

Assessing soundscape: Comparison between in situ and laboratory methodologies

Directory of Open Access Journals (Sweden)

Hermida Cadena Luis Fernando

2017-06-01

Full Text Available The assessment of soundscape implies an interdisciplinary approach, where objective and subjective aspects are considered. For the subjective evaluation, in situ and laboratory methodologies are usually followed. Local observations allow the collection of information on the influence of different stimuli present in the environment, whereas laboratory tests present a determined quantity of controlled stimuli to the evaluator. The purpose of this work is to compare results from the different methodologies in order to understand their strengths and their weaknesses. Three urban parks in the city of Lisbon, Portugal, were evaluated. Fragments of binaural sound recordings collected in the parks were used in laboratory tests to compare with the responses in situ and of expert and nonexpert listeners. Statistically significant differences were found in several of the perceptual attributes under observation, which led to variation in the results of the main model’s components. The sound environments were found to be more pleasant and uneventful in situ than in the laboratory, a phenomenon possibly due to the influence of other stimuli such as visual in the process of assessment. The in situ tests allow a systemic and holistic evaluation of the environment under study,whereas the laboratory tests allow a specific and tightly targeted analysis of different component sound events. Therefore, the two methodologies can be useful in soundscape assessment depending on the specific application and needs. No differences were found in the assessment made by either experts or nonexperts.

Prediction of retained residual stresses in laboratory fracture mechanics specimens extracted from welded components

International Nuclear Information System (INIS)

Hurlston, R.G.; Sherry, A.H.; James, P.; Sharples, J.K.

2015-01-01

The measurement of weld material fracture toughness properties is important for the structural integrity assessment of engineering components. However, welds can contain high levels of residual stress and these can be retained in fracture mechanics specimens, particularly when machined from non-stress relieved welds. Retained residual stresses can make the measurement of valid fracture toughness properties difficult. This paper describes the results of analytical work undertaken to investigate factors that can influence the magnitude and distribution of residual stresses retained in fracture mechanics specimen blanks extracted from as-welded ferritic and austenitic stainless steel plates. The results indicate that significant levels of residual stress can be retained in specimen blanks prior to notching, and that the magnitude and distribution of stress is dependent upon material properties, specimen geometry and size, and extraction location through the thickness of the weld. Finite element modelling is shown to provide a useful approach for estimating the level and distributions of retained residual stresses. A new stress partitioning approach has been developed to estimate retained stress levels and results compare favourably with FE analysis and available experimental data. The approach can help guide the selection of specimen geometry and machining strategies to minimise the level of residual stresses retained in fracture mechanics specimen blanks extracted from non stress-relieved welds and thus improve the measurement of weld fracture toughness properties. - Highlights: • A simplified method for generating realistic weld residual stresses has been developed. • It has been shown that significant levels of residual stress can be retained within laboratory fracture mechanics specimens. • The level and distribution is dependant upon material, specimen type, specimen size and extraction location. • A method has been developed to allow estimates of the

Strategies for laboratory cost containment and for pathologist shortage: centralised pathology laboratories with microwave-stimulated histoprocessing and telepathology.

Science.gov (United States)

Leong, Anthony S Y; Leong, F Joel W M

2005-02-01

The imposition of laboratory cost containment, often from external forces, dictates the necessity to develop strategies to meet laboratory cost savings. In addition, the national and worldwide shortage of anatomical pathologists makes it imperative to examine our current practice and laboratory set-ups. Some of the strategies employed in other areas of pathology and laboratory medicine include improvements in staff productivity and the adoption of technological developments that reduce manual intervention. However, such opportunities in anatomical pathology are few and far between. Centralisation has been an effective approach in bringing economies of scale, the adoption of 'best practices' and the consolidation of pathologists, but this has not been possible in anatomical pathology because conventional histoprocessing takes a minimum of 14 hours and clinical turnaround time requirements necessitate that the laboratory and pathologist be in proximity and on site. While centralisation of laboratories for clinical chemistry, haematology and even microbiology has been successful in Australia and other countries, the essential requirements for anatomical pathology laboratories are different. In addition to efficient synchronised courier networks, a method of ultra-rapid tissue processing and some expedient system of returning the prepared tissue sections to the remote laboratory are essential to maintain the turnaround times mandatory for optimal clinical management. The advent of microwave-stimulated tissue processing that can be completed in 30-60 minutes and the immediate availability of compressed digital images of entire tissue sections via telepathology completes the final components of the equation necessary for making centralised anatomical pathology laboratories a reality.

Experience with copper oxide production in antiproton source components at Fermi National Accelerator Laboratory

International Nuclear Information System (INIS)

Ader, Christine R.; Harms, Elvin R. Jr; Morgan, James P.

2000-01-01

The Antiproton (Pbar) Source at Fermi National Accelerator Laboratory is a facility comprised of a target station, two rings called the Debuncher and Accumulator and the transport lines between those rings and the remainder of the particle accelerator complex. Water is by far the most common medium for carrying excess heat away from components, primarily electromagnets, in this facility. The largest of the water systems found in Pbar is the 95 degree Fahrenheit Low Conductivity Water (LCW) system. LCW is water which has had free ions removed, increasing its resistance to electrical current. This water circuit is used to cool magnets, power supplies, and stochastic cooling components and typically has a resistivity of 11--18 megaohms-cm. For more than ten years the Antiproton rings were plagued with overheating magnets due to plugged water-cooling channels. Various repairs have been tried over the years with no permanent success. Throughout all of this time, water samples have indicated copper oxide, CuO, as the source of the contamination. Matters came to a head in early 1997 following a major underground LCW leak between the Central Utilities Building and the Antiproton Rings enclosures. Over a span of several weeks following system turn-on, some twenty magnets overheated leading to unreliable Pbar source operation. Although it was known that oxygen in the system reacts with the copper tubing to form CuO, work to remedy this problem was not undertaken until this time period. Leaks, large quantities of make-up water, infrequent filter replacement, and thermal cycling also result in an increase in the corrosion product release rate. A three-pronged approach has been implemented to minimize the amount of copper oxide available to plug the magnets: (1) installation of an oxygen removal system capable of achieving dissolved oxygen concentrations in the parts per billion (ppb) range; (2) regular closed-loop filter/flushing of the copper headers and magnets and stainless

Em alguns casos, as lavouras são pulverizadas duas a quatro vezes por semana, sem sucesso. Isto acontece porque, em muitos casos, são empregados inseticidas ineficientes, para os quais a praga já apresenta resistência. Trabalhos anteriores demonstraram ser possível determinar os inseticidas ineficazes para o controle da TDC em testes de laboratório, através do uso da dosagem recomendada. Neste trabalho foram coletadas larvas e pupas do inseto nos estados do Ceará (Tianguá, Minas Gerais (Barroso, Bahia (Mucugê, Mato Grosso (Sinop e no Distrito Federal (Brazlândia e Embrapa Hortaliças. As populações foram criadas em laboratório e, dependendo do número de larvas de primeira geração, estas foram tratadas com as dosagens recomendadas de abamectin, acefato, B. thuringiensis, cartap, clorfluazuron, deltametrina e spinosad. Foi previamente assumido que um inseticida eficiente seria aquele que causasse a mortalidade de mais de 90% das larvas. Os resultados mostraram que a eficiência dos inseticidas variou entre as diferentes áreas. Spinosad causou a mortalidade de l00% das larvas em todos os locais.

Exploratory monitoring of radon is conducted at one site at the deep underground Gran Sasso National Laboratory (LNGS; 1,000m below the surface). Monitoring is performed in a small secluded space separated by a sealed partition from the entirety of the laboratory environment in air in contact with the exposed surrounding calcareous country rock. Overall radon levels are low (0.45 kBq/m3). Utilizing both alpha and gamma-ray detectors measurements (15-minute resolution) cover a time span of ca. 600 days. Systematic and recurring radon signals are recorded consisting of two primary signal types: a) non-periodic Multi-Day (MD) signals lasting 2-10 days, and b) Daily Radon (DR) signals - which are of a periodic nature exhibiting a primary 24-hour cycle. Temperature in the closed enclosure is stable (11.5±0.3 °C) and pressure reflects above surface barometric variations. Analysis and comparison in the time and frequency domains (FFT) of local environmental data (P, T) indicates that these do not drive radon variation in air at the site. The phenomenology of the MD and DR signals is similar to situations encountered at other locations where radon is monitored with a high time resolution in geogas at upper crustal levels. Using the Continuous Wavelet Transform analysis tool a different variation pattern is observed for time series consisting of day-time and night-time measurement of the gamma radiation from radon progeny. Applying the same analysis to the time series of local air pressure does not reveal a day-time and night-time difference. The observation of a differing day/night pattern in the gamma radiation from radon at LNGS is similar to further occurrences at other subsurface locations. Production of a day/night pattern must be related to rotation of Earth around its axis. This phenomenon is a further confirmation of the recent proposition as to the influence of a component of solar irradiance on the nuclear radiation from radon in air. The occurrence of these

During the waste vitrification process, troublesome minor components in low-level radioactive waste streams could adversely affect either waste vitrification rate or melter life-time. Knowing the solubility limits for these minor components is important to determine pretreatment options for waste streams and glass formulation to prevent or to minimize these problems during the waste vitrification. A joint study between Pacific Northwest Laboratory and Rensselaer Polytechnic Institute has been conducted to determine minor component impacts in low-level nuclear waste glass

Visando confirmar e entender o padrão observado no campo, aspectos bioecológicos como oviposição e mortalidade de imaturos foram comparados em condições semi-controladas de casa de vegetação com plantas cultivadas em vasos com solo proveniente do sistema orgânico e convencional. Adultos da traça-do-tomateiro foram liberados na casa de vegetação e após 24h, as plantas infestadas foram transferidas para outra casa de vegetação, para acompanhamento de coortes horizontais. Os ovos naturalmente depositados pela traça-do-tomateiro foram localizados na planta e demarcados. Em seguida, a folha foi ensacada. Diariamente as plantas foram observadas, registrando a fase de desenvolvimento do inseto e a ocorrência de morte, até que todos os insetos completassem seu ciclo de vida. A oviposição pela traça-do-tomateiro em plantas com solos oriundos do sistema convencional foi duas vezes maior do que em plantas com solos do sistema orgânico. A curva de sobrevivência da fase imatura e a tabela de vida da traça-do-tomateiro em casa de vegetação mostraram que a sobrevivência em plantas com solo orgânico e convencional não apresentaram diferenças. Assim as diferenças no comportamento de padrão de oviposição observadas a campo provavelmente não estão relacionadas com o desempenho da progênie e podem ser influenciado pelo ambiente proporcionado pelo sistema orgânico de produção.The tomato pinworm presented higher oviposition when colonizing tomato plants cropped in conventional system than in organic system, in previous field studies.

Genetic associations involving both rare and common alleles have been reported for schizophrenia but there have been no systematic scans for rare recessive genotypes using fully phased trio data. Here, we use exome sequencing in 604 schizophrenia proband-parent trios to investigate the role of recessive (homozygous or compound heterozygous) nonsynonymous genotypes in the disorder. The burden of recessive genotypes was not significantly increased in probands at either a genome-wide level or in any individual gene after adjustment for multiple testing. At a system level, probands had an excess of nonsynonymous compound heterozygous genotypes (minor allele frequency, MAF ⩽ 1%) in voltage-gated sodium channels (VGSCs; eight in probands and none in parents, P = 1.5 × 10(-)(4)). Previous findings of multiple de novo loss-of-function mutations in this gene family, particularly SCN2A, in autism and intellectual disability provide biological and genetic plausibility for this finding. Pointing further to the involvement of VGSCs in schizophrenia, we found that these genes were enriched for nonsynonymous mutations (MAF ⩽ 0.1%) in cases genotyped using an exome array, (5585 schizophrenia cases and 8103 controls), and that in the trios data, synaptic proteins interacting with VGSCs were also enriched for both compound heterozygosity (P = 0.018) and de novo mutations (P = 0.04). However, we were unable to replicate the specific association with compound heterozygosity at VGSCs in an independent sample of Taiwanese schizophrenia trios (N = 614). We conclude that recessive genotypes do not appear to make a substantial contribution to schizophrenia at a genome-wide level. Although multiple lines of evidence, including several from this study, suggest that rare mutations in VGSCs contribute to the disorder, in the absence of replication of the original findings regarding compound heterozygosity, this conclusion requires evaluation in a larger sample of trios.

The traditional process for developing large-scale simulations is cumbersome, time consuming, costly, and in some cases, inadequate. The topics of software components and component-based software engineering are being explored by software professionals in academic and industrial settings. A component is a well-delineated, relatively independent, and replaceable part of a software system that performs a specific function. Many researchers have addressed the potential to derive a component-based approach to simulations in general, and a few have focused on military simulations in particular. In a component-based approach, functional or logical blocks of the simulation entities are represented as coherent collections of components satisfying explicitly defined interface requirements. A simulation is a top-level aggregate comprised of a collection of components that interact with each other in the context of a simulated environment. A component may represent a simulation artifact, an agent, or any entity that can generated events affecting itself, other simulated entities, or the state of the system. The component-based approach promotes code reuse, contributes to reducing time spent validating or verifying models, and promises to reduce the cost of development while still delivering tailored simulations specific to analysis questions. The Integrated Virtual Environment for Simulation (IVES) is a composition-centered framework to achieve this potential. IVES is a Java implementation of simulation composition concepts developed at Los Alamos National Laboratory for use in several application domains. In this paper, its use in the military domain is demonstrated via the simulation of dismounted infantry in an urban environment.

Reliability estimation for check valves and other components

1996-01-01

For years the nuclear industry has depended upon component operational reliability information compiled from reliability handbooks and other generic sources as well as private databases generated by recognized experts both within and outside the nuclear industry. Regrettably, these technical bases lacked the benefit of large-scale operational data and comprehensive data verification, and did not take into account the parameters and combinations of parameters that affect the determination of failure rates. This paper briefly examines the historic use of generic component reliability data, its sources, and its limitations. The concept of using a single failure rate for a particular component type is also examined. Particular emphasis is placed on check valves due to the information available on those components. The Appendix presents some of the results of the extensive analyses done by Oak Ridge National Laboratory (ORNL) on check valve performance

Laboratory automation: trajectory, technology, and tactics.

Markin, R S; Whalen, S A

Laboratory automation is in its infancy, following a path parallel to the development of laboratory information systems in the late 1970s and early 1980s. Changes on the horizon in healthcare and clinical laboratory service that affect the delivery of laboratory results include the increasing age of the population in North America, the implementation of the Balanced Budget Act (1997), and the creation of disease management companies. Major technology drivers include outcomes optimization and phenotypically targeted drugs. Constant cost pressures in the clinical laboratory have forced diagnostic manufacturers into less than optimal profitability states. Laboratory automation can be a tool for the improvement of laboratory services and may decrease costs. The key to improvement of laboratory services is implementation of the correct automation technology. The design of this technology should be driven by required functionality. Automation design issues should be centered on the understanding of the laboratory and its relationship to healthcare delivery and the business and operational processes in the clinical laboratory. Automation design philosophy has evolved from a hardware-based approach to a software-based approach. Process control software to support repeat testing, reflex testing, and transportation management, and overall computer-integrated manufacturing approaches to laboratory automation implementation are rapidly expanding areas. It is clear that hardware and software are functionally interdependent and that the interface between the laboratory automation system and the laboratory information system is a key component. The cost-effectiveness of automation solutions suggested by vendors, however, has been difficult to evaluate because the number of automation installations are few and the precision with which operational data have been collected to determine payback is suboptimal. The trend in automation has moved from total laboratory automation to a

Kristiansen, M, Samani, A, Madeleine, P, and Hansen, EA. Effects of 5 weeks of bench press training on muscle synergies: A randomized controlled study. J Strength Cond Res 30(7): 1948-1959, 2016-The ability to perform forceful muscle contractions has important implications in sports performance and in activities of daily living. However, there is a lack of knowledge on adaptations in intermuscular coordination after strength training. The purpose of this study was therefore to assess muscle synergies before and after 5 weeks of bench press training. Thirty untrained male subjects were randomly allocated to a training group (TRA) or a control group (CON). After the pretest, TRA completed 5 weeks of bench press training, before completing a posttest, whereas subjects in CON continued their normal life. During test sessions, surface electromyography (EMG) was recorded from 13 different muscles. Muscle synergies were extracted from EMG data using nonnegative matrix factorization. To evaluate differences between pretest and posttest, we performed a cross-correlation analysis and a cross-validation analysis, in which the synergy components extracted in the pretest session were recomputed, using the fixed synergy components from the posttest session. Two muscle synergies accounted for 90% of the total variance and reflected the concentric and eccentric phase, respectively. TRA significantly increased 3 repetition maximum in bench press with 19.0% (25th; 75th percentile, 10.3%; 21.7%) (p < 0.001), whereas no change occurred in CON. No significant differences were observed in synergy components between groups. However, decreases in correlation values for intragroup comparisons in TRA may suggest that the synergy components changed, whereas this was not the case in CON. Strength and conditioning professionals may consider monitoring changes in muscle synergies in training and rehabilitation programs as a way to benchmark changes in intermuscular coordination.

Inflammation Thread Runs across Medical Laboratory Specialities

Urs Nydegger

Full Text Available We work on the assumption that four major specialities or sectors of medical laboratory assays, comprising clinical chemistry, haematology, immunology, and microbiology, embraced by genome sequencing techniques, are routinely in use. Medical laboratory markers for inflammation serve as model: they are allotted to most fields of medical lab assays including genomics. Incessant coding of assays aligns each of them in the long lists of big data. As exemplified with the complement gene family, containing C2, C3, C8A, C8B, CFH, CFI, and ITGB2, heritability patterns/risk factors associated with diseases with genetic glitch of complement components are unfolding. The C4 component serum levels depend on sufficient vitamin D whilst low vitamin D is inversely related to IgG1, IgA, and C3 linking vitamin sufficiency to innate immunity. Whole genome sequencing of microbial organisms may distinguish virulent from nonvirulent and antibiotic resistant from nonresistant varieties of the same species and thus can be listed in personal big data banks including microbiological pathology; the big data warehouse continues to grow.

Full Text Available A traça-do-tomateiro foi constatada pela primeira vez no Brasil em 1980 estando hoje dentre as principais pragas da tomaticultura nacional. O controle desta praga é feito principalmente por inseticidas, sendo realizada em casos extremos, até três pulverizações semanais. Acessos silvestres de tomateiro como S. pennellii LA-716 possuem resistência a pragas, mediada pela presença de acilaçúcares nos folíolos. Os objetivos deste trabalho foram obter genótipos de tomateiro com características comerciais e altos teores foliares de acilaçúcares (AA, e avaliar seus níveis de resistência à traça do tomateiro Tuta absoluta. Os genótipos foram obtidos a partir de populações segregantes (F2 oriundas do cruzamento entre AF-8665 (linhagem elite com baixos teores de AA e as linhagens BPX370E-30-275-11-7, BPX370E-30-275-11-8, BPX370E-30-380-68-6 e BPX370E-30-380-68-8 (linhagens pré-comerciais com altos teores, obtidas a partir do cruzamento interespecífico S. lycopersicum x S. pennellii LA-716.

Genótipos selecionados para altos teores de AA expressaram menor ovoposição da traça e níveis inferiores de danos causados à planta pela infestação do microlepidóptero do que genótipos (comerciais ou não com baixos teores de AA. Embora genótipos com altos teores de AA tenham sido mais resistentes à traça do que os demais, seus níveis de resistência podem ser dependentes do background genotípico: clones BPX-410H (alto teor de AA mostraram-se em geral ligeiramente mais resistentes do que o dos clones BPX-370G (também alto teor de AA. Os clones BPX-410H-01pl#281, BPX-410H-04pl#348 e BPX-410H-04pl#481 foram superiores nas avaliações de resistência à traça e são recomendados para a continuidade do programa de melhoramento.The South American tomato pinworm was first detected in Brazil

In many insect species maternal provision of sex-specifically spliced messenger RNA (mRNA) of sex determination genes is an essential component of the sex determination mechanism. In haplodiploid Hymenoptera, maternal provision in combination with genomic imprinting has been shown for the parasitoid Nasonia vitripennis, known as maternal effect genomic imprinting sex determination (MEGISD). Here, we characterize the sex determination cascade of Asobara tabida, another hymenopteran parasitoid. We show the presence of the conserved sex determination genes doublesex (dsx), transformer (tra) and transformer-2 (tra2) orthologues in As. tabida. Of these, At-dsx and At-tra are sex-specifically spliced, indicating a conserved function in sex determination. At-tra and At-tra2 mRNA is maternally provided to embryos but, in contrast to most studied insects, As. tabida females transmit a non-sex-specific splice form of At-tra mRNA to the eggs. In this respect, As. tabida sex determination differs from the MEGISD mechanism. How the paternal genome can induce female development in the absence of maternal provision of sex-specifically spliced mRNA remains an open question. Our study reports a hitherto unknown variant of maternal effect sex determination and accentuates the diversity of insect sex determination mechanisms. © 2017 The Authors.

Development of damage functions for high-rise building components

Kustu, O.; Miller, D.D.; Brokken, S.T.

1982-10-01

The component approach for predicting the effects that ground motion from underground nuclear explosions will have on structures involves predicting the damage to each structural and nonstructural component of a building on the basis of the expected local deformation that most affects the damage to the component. This study was conducted to provide the basic data necessary to evaluate the component approach. Available published laboratory test data for various high-rise building components were collected. These data were analyzed statistically to determine damage threshold values and their variabilities, which in turn were used to derive component damage functions. The portion of construction costs attributable to various building components was determined statistically. This information was needed because component damage functions define damage as a percentage of the replacement values of the component, and, in order to calculate the overall building damage factor, the relative cost of each component must be estimated. The feasibility of the component approach to damage prediction is demonstrated. It is recommended that further experimental research directed towards developing an adequate data base of component damage thresholds for all significant building components should be encouraged. Parallel to this effort, detailed damage data from specific buildings damaged in earthquakes should be collected to verify the theoretical procedure

The purpose of this report is to document the work that was performed at the Oak Ridge National Laboratory (ORNL) in support of the development of high temperature power electronics and components with monies remaining from the Semikron High Temperature Inverter Project managed by the National Energy Technology Laboratory (NETL). High temperature electronic components are needed to allow inverters to operate in more extreme operating conditions as required in advanced traction drive applications. The trend to try to eliminate secondary cooling loops and utilize the internal combustion (IC) cooling system, which operates with approximately 105 C water/ethylene glycol coolant at the output of the radiator, is necessary to further reduce vehicle costs and weight. The activity documented in this report includes development and testing of high temperature components, activities in support of high temperature testing, an assessment of several component packaging methods, and how elevated operating temperatures would impact their reliability. This report is organized with testing of new high temperature capacitors in Section 2 and testing of new 150 C junction temperature trench insulated gate bipolar transistor (IGBTs) in Section 3. Section 4 addresses some operational OPAL-GT information, which was necessary for developing module level tests. Section 5 summarizes calibration of equipment needed for the high temperature testing. Section 6 details some additional work that was funded on silicon carbide (SiC) device testing for high temperature use, and Section 7 is the complete text of a report funded from this effort summarizing packaging methods and their reliability issues for use in high temperature power electronics. Components were tested to evaluate the performance characteristics of the component at different operating temperatures. The temperature of the component is determined by the ambient temperature (i.e., temperature surrounding the device) plus the

CANDU steam generator life management: laboratory data and plant experience

As CANDU reactors enter middle age, and the potential value of the plants in a deregulated market is realized, life management and life extension issues become increasingly important. An accurate assessment of critical components, such as the CANDU 6 steam generators (SGs), is crucial for successful life extension, and in this context, material issues are a key factor. For example, service experience with Alloy 900 tubing indicates very low levels of degradation within CANDU SGs; the same is also noted worldwide. With little field data for extrapolation, life management and life extension decisions for the tube bundles rely heavily on laboratory data. Similarly, other components of the SGs, in particular the secondary side internals, have only limited inspection data upon which to base a condition assessment. However, in this case there are also relatively little laboratory data. Decisions on life management and life extension are further complicated--not only is inspection access often restricted, but repair or replacement options for internal components are, by definition, also limited. The application of CANDU SG life management and life extension requires a judicious blend of in-service data, laboratory research and development (R and D) and materials and engineering judgment. For instance, the available laboratory corrosion and fretting wear data for Alloy 800 SG tubing have been compared with plant experience (with all types of tubing), and with crevice chemistry simulations, in order to provide an appropriate inspection guide for a 50-year SG life. A similar approach has been taken with other SG components, where the emphasis has been on known degradation mechanisms worldwide. This paper provides an outline of the CANDU SG life management program, including the results to date, a summary of the supporting R and D program showing the integration with condition assessment and life management activities, and the approach taken to life extension for a typical

Backman, C.; Hoeschele, M.

2013-07-01

Characterizing the performance of hot water distribution systems is a critical step in developing best practice guidelines for the design and installation of high performance hot water systems. Developing and validating simulation models is critical to this effort, as well as collecting accurate input data to drive the models. In this project, the ARBI team validated the newly developed TRNSYS Type 604 pipe model against both detailed laboratory and field distribution system performance data. Validation efforts indicate that the model performs very well in handling different pipe materials, insulation cases, and varying hot water load conditions. Limitations of the model include the complexity of setting up the input file and long simulation run times. In addition to completing validation activities, this project looked at recent field hot water studies to better understand use patterns and potential behavioral changes as homeowners convert from conventional storage water heaters to gas tankless units. Based on these datasets, we conclude that the current Energy Factor test procedure overestimates typical use and underestimates the number of hot water draws. This has implications for both equipment and distribution system performance. Gas tankless water heaters were found to impact how people use hot water, but the data does not necessarily suggest an increase in usage. Further study in hot water usage and patterns is needed to better define these characteristics in different climates and home vintages.

Modern, forensics laboratories need Laboratory Information Management Systems (LIMS) implementations that allow the lab to track evidentiary items through their examination lifecycle and also serve all pertinent laboratory personnel. The research presented here presents LIMS core requirements as viewed by respondents serving in different forensic laboratory capacities as well as different forensic laboratory environments. A product-development methodology was employed to evaluate the relative value of the key features that constitute a LIMS, in order to develop a set of relative values for these features and the specifics of their implementation. In addition to the results of the product development analysis, this paper also provides an extensive review of LIMS and provides an overview of the preparation and planning process for the successful upgrade or implementation of a LIMS. Analysis of the data indicate that the relative value of LIMS components are viewed differently depending upon respondents' job roles (i.e., evidence technicians, scientists, and lab management), as well as by laboratory size. Specifically, the data show that: (1) Evidence technicians place the most value on chain of evidence capabilities and on chain of custody tracking; (2) Scientists generally place greatest value on report writing and generation, and on tracking daughter evidence that develops during their analyses; (3) Lab. Managers place the greatest value on chain of custody, daughter evidence, and not surprisingly, management reporting capabilities; and (4) Lab size affects LIMS preference in that, while all labs place daughter evidence tracking, chain of custody, and management and analyst report generation as their top three priorities, the order of this prioritization is size dependent.

Experiential learning in control systems laboratories and engineering project management

Reck, Rebecca Marie

Experiential learning is a process by which a student creates knowledge through the insights gained from an experience. Kolb's model of experiential learning is a cycle of four modes: (1) concrete experience, (2) reflective observation, (3) abstract conceptualization, and (4) active experimentation. His model is used in each of the three studies presented in this dissertation. Laboratories are a popular way to apply the experiential learning modes in STEM courses. Laboratory kits allow students to take home laboratory equipment to complete experiments on their own time. Although students like laboratory kits, no previous studies compared student learning outcomes on assignments using laboratory kits with existing laboratory equipment. In this study, we examined the similarities and differences between the experiences of students who used a portable laboratory kit and students who used the traditional equipment. During the 2014- 2015 academic year, we conducted a quasi-experiment to compare students' achievement of learning outcomes and their experiences in the instructional laboratory for an introductory control systems course. Half of the laboratory sections in each semester used the existing equipment, while the other sections used a new kit. We collected both quantitative data and qualitative data. We did not identify any major differences in the student experience based on the equipment they used. Course objectives, like research objectives and product requirements, help provide clarity and direction for faculty and students. Unfortunately, course and laboratory objectives are not always clearly stated. Without a clear set of objectives, it can be hard to design a learning experience and determine whether students are achieving the intended outcomes of the course or laboratory. In this study, I identified a common set of laboratory objectives, concepts, and components of a laboratory apparatus for undergraduate control systems laboratories. During the summer of

1999-01-01

Studies of flow through the unsaturated zone and perched ground-water zones above the Snake River Plain aquifer are part of the overall assessment of ground-water flow and determination of the fate and transport of contaminants in the subsurface at the Idaho National Engineering and Environmental Laboratory (INEEL). These studies include definition of the hydrologic controls on the formation of perched ground-water zones and description of the transport and fate of wastewater constituents as they moved through the unsaturated zone. The definition of hydrologic controls requires stratigraphic correlation of basalt flows and sedimentary interbeds within the saturated zone, analysis of hydraulic properties of unsaturated-zone rocks, numerical modeling of the formation of perched ground-water zones, and batch and column experiments to determine rock-water geochemical processes. This report describes the development of a transient numerical simulation that was used to evaluate a conceptual model of flow through perched ground-water zones beneath wastewater infiltration ponds at the Test Reactor Area (TRA)

Boris Bortnik

2017-12-01

Full Text Available This article aims to determine the effect of a virtual chemistry laboratory on university student achievement. The article describes a model of a laboratory course that includes a virtual component. This virtual component is viewed as a tool of student pre-lab autonomous learning. It presents electronic resources designed for a virtual laboratory and outlines the methodology of e-resource application. To find out how virtual chemistry laboratory affects student scientific literacy, research skills and practices, a pedagogical experiment has been conducted. Student achievement was compared in two learning environments: traditional – in-class hands-on – learning (control group and blended learning – online learning combined with in-person learning (experimental group. The effectiveness of integrating an e-lab in the laboratory study was measured by comparing student lab reports of the two groups. For that purpose, a set of 10 criteria was developed. The experimental and control student groups were also compared in terms of test results and student portfolios. The study showed that the adopted approach blending both virtual and hands-on learning environments has the potential to enhance student research skills and practices in analytical chemistry studies.

Hazardous waste management in research laboratories

1989-01-01

Hazardous waste management in research laboratories benefits from a fundamentally different approach to the hazardous waste determination from industry's. This paper introduces new, statue-based criteria for identifying hazardous wastes (such as radiological mixed wastes and waste oils) and links them to a forward-looking compliance of laboratories, the overall system integrates hazardous waste management activities with other environmental and hazard communication initiatives. It is generalizable to other waste generators, including industry. Although only the waste identification and classification aspects of the system are outlined in detail here, four other components are defined or supported, namely: routine and contingency practices; waste treatment/disposal option definition and selection; waste minimization, recycling, reuse, and substitution opportunities; and key interfaces with other systems, including pollution prevention

L’incontro di Bruno Munari con la didattica attiva. I fondamenti pedagogici dei laboratori "Giocare con l’arte".

Laura Panizza

Full Text Available Il saggio affronta il tema: quali idee pedagogiche hanno influenzato la progettazione dei laboratori "Giocare con l’arte", ideati da Bruni Munari negli anni Settanta e destinati a trasformare profondamente il modo d’intendere la didattica museale e l’educazione estetico-artistica. L’ipotesi dell’autrice è che questi laboratori riprendano alcuni principi dell’attivismo pedagogico, a cui Munari non fa però esplicito riferimento nei suoi scritti. Per questo motivo, il saggio cerca di ricostruire gli incontri più significativi che possono aver mediato l’approccio alla didattica attiva, soffermandosi in particolare sui rapporti di collaborazione intessuti da Munari con lo scrittore Gianni Rodari e con il pedagogista Giovanni Belgrano. Sia Rodari, sia Belgrano erano legati – seppure con diverse modalità – al Movimento di Cooperazione Educativa, che si proponeva di rinnovare la scuola italiana ispirandosi alla pedagogia deweyana. Attraverso la loro mediazione, Munari può essersi avvicinato all’attivismo, di cui condivideva peraltro molteplici assunti: dall’esigenza di promuovere la creatività del bambino, mediante la sperimentazione di materiali e tecniche, alla concezione dell’educatore come animatore delle attività volte alla padronanza dei saperi. In tal senso, il saggio si propone anche di mostrare la continuità esistente tra questa linea teorica e la riflessione sulla democratizzazione dell’arte intrapresa da Munari già nel 1948, con la fondazione – insieme ad altri artisti – del Movimento Arte Concreta.

The Component-Based Application for GAMESS

Energy Technology Data Exchange (ETDEWEB)

Peng, Fang [Iowa State Univ., Ames, IA (United States)

2007-01-01

GAMESS, a quantum chetnistry program for electronic structure calculations, has been freely shared by high-performance application scientists for over twenty years. It provides a rich set of functionalities and can be run on a variety of parallel platforms through a distributed data interface. While a chemistry computation is sophisticated and hard to develop, the resource sharing among different chemistry packages will accelerate the development of new computations and encourage the cooperation of scientists from universities and laboratories. Common Component Architecture (CCA) offers an enviromnent that allows scientific packages to dynamically interact with each other through components, which enable dynamic coupling of GAMESS with other chetnistry packages, such as MPQC and NWChem. Conceptually, a cotnputation can be constructed with "plug-and-play" components from scientific packages and require more than componentizing functions/subroutines of interest, especially for large-scale scientific packages with a long development history. In this research, we present our efforts to construct cotnponents for GAMESS that conform to the CCA specification. The goal is to enable the fine-grained interoperability between three quantum chemistry programs, GAMESS, MPQC and NWChem, via components. We focus on one of the three packages, GAMESS; delineate the structure of GAMESS computations, followed by our approaches to its component development. Then we use GAMESS as the driver to interoperate integral components from the other tw"o packages, arid show the solutions for interoperability problems along with preliminary results. To justify the versatility of the design, the Tuning and Analysis Utility (TAU) components have been coupled with GAMESS and its components, so that the performance of GAMESS and its components may be analyzed for a wide range of systetn parameters.

Standardization of medical terminology is essential for data transmission between health-care institutions or clinical laboratories and for maximizing the benefits of information technology. Purpose of our study was to standardize the medical terms used in the clinical laboratory, such as test names, units, terms used in result descriptions, etc. During the first year of the study, we developed a standard database of concept names for laboratory terms, which covered the terms used in government health care centers, their branch offices, and primary health care units. Laboratory terms were collected from the electronic data interchange (EDI) codes from National Health Insurance Corporation (NHIC), Logical Observation Identifier Names and Codes (LOINC) database, community health centers and their branch offices, and clinical laboratories of representative university medical centers. For standard expression, we referred to the English-Korean/ Korean-English medical dictionary of Korean Medical Association and the rules for foreign language translation. Programs for mapping between LOINC DB and EDI code and for translating English to Korean were developed. A Korean standard laboratory terminology database containing six axial concept names such as components, property, time aspect, system (specimen), scale type, and method type was established for 7,508 test observations. Short names and a mapping table for EDI codes and Unified Medical Language System (UMLS) were added. Synonym tables for concept names, words used in the database, and six axial terms were prepared to make it easier to find the standard terminology with common terms used in the field of laboratory medicine. Here we report for the first time a Korean standard laboratory terminology database for test names, result description terms, result units covering most laboratory tests in primary healthcare centers.

Nello specifico, intende verificare la validità di una nuova chiave di lettura dei processi di governance del territorio, detta situazionista, che affianca la concezione prevalente in letteratura, definita unitaria o sistemica. Il punto di discrepanza principale tra le due visioni sembra essere quello della vocazione territoriale. Pur riconoscendo entrambe la presenza di interessi condivisi tra gli attori, la visione situazionista non riconosce alla vocazione la funzione “razionalizzante” riscontrabile nell’approccio sistemico. A seguito di una sintetica review della letteratura sui temi del territorio come cultura condivisa, sulla dimensione reticolare territoriale ed extraterritoriale e sul contratto di rete, verrà introdotto lo studio di un contratto di rete stipulato l’8 giugno 2010 tra le aziende che costituiscono il Polo Alta Moda Area Vestina. Attraverso le evidenze emerse da alcune interviste in profondità, sarà indagato il ruolo dell’azienda Brioni nella duplice veste di key player del territorio e di impresa capofila del contratto di rete analizzato e saranno esaminati gli altri attori che compongono il Polo Alta Moda.

Report formatting in laboratory medicine - a call for harmony.

The results of medical laboratory testing are only useful if they lead to appropriate actions by medical practitioners and/or patients. An underappreciated component of the medical testing process is the transfer of the information from the laboratory report into the reader's brain. The format of laboratory reports can be determined by the testing laboratory, which may issue a formatted report, or by electronic systems receiving information from laboratories and controlling the report format. As doctors can receive information from many laboratories, interpreting information from reports in a safe and rapid manner is facilitated by having similar report layouts and formats. Using Australia as an example, there is a wide variation in report formats in spite of a body of work to define standards for reporting. In addition to standardising of report formats, consideration needs to be given to optimisation of report formatting to facilitate rapid and unambiguous reading of the report and also interpretation of the data. Innovative report formats have been developed by some laboratories; however, wide adoption has not followed. The need to balance uniformity of reporting with appropriate innovation is a challenge for safe reporting of laboratory results. This paper discusses the current status and opportunity for improvement in safety and efficiency of the reading of laboratory reports, using current practise and developments in Australia as examples.

Theoretical Study of Molecular Determinants Involved in Signal Binding to the TraR Protein of Agrobacterium tumefaciens

Full Text Available N-acylated homoserine lactone (AHL mediated cell-cell communication in bacteria is dependent on the recognition of the cognate signal by its receptor. This interaction allows the receptor-ligand complex to act as a transcriptional activator, controlling the expression of a range of bacterial phenotypes, including virulence factor expression and biofilm formation. One approach to determine the key features of signal- binding is to model the intermolecular interactions between the receptor and ligand using computational-based modeling software (LigandFit. In this communication, we have modeled the crystal structure of the AHL receptor protein TraR and its AHL signal N-(3- oxooctanoyl-homoserine lactone from Agrobacterium tumefaciens and compared it to the previously reported antagonist behaviour of a number of AHL analogues, in an attempt to determine structural constraints for ligand binding. We conclude that (i a common conformation of the AHL in the hydrophobic and hydrophilic region exists for ligand-binding, (ii a tail chain length threshold of 8 carbons is most favourable for ligand-binding affinity, (iii the positive correlation in the docking studies could be used a virtual screening tool.

Thermal aging of some decommissioned reactor components and methodology for life prediction

International Nuclear Information System (INIS)

Chung, H.M.

1989-03-01

Since a realistic aging of cast stainless steel components for end-of-life or life-extension conditions cannot be produced, it is customary to simulate the thermal aging embrittlement by accelerated aging at ∼400 degree C. In this investigation, field components obtained from decommissioned reactors have been examined after service up to 22 yr to provide a benchmark of the laboratory simulation. The primary and secondary aging processes were found to be identical to those of the laboratory-aged specimens, and the kinetic characteristics were also similar. The extent of the aging embrittlement processes and other key factors that are known to influence the embrittlement kinetics have been compared for the decommissioned reactor components and materials aged under accelerated conditions. On the basis of the study, a mechanistic understanding of the causes of the complex behavior in kinetics and activation energy of aging (i.e., the temperature dependence of aging embrittlement between the accelerated and reactor-operating conditions) is presented. A mechanistic correlation developed thereon is compared with a number of available empirical correlations to provide an insight for development of a better methodology of life prediction of the reactor components. 18 refs., 18 figs., 5 tabs

The development of such a test-bed using an off-the-shelf PEM fuel cell, lithium-ion battery and DC/DC converter is presented here, and its application to a hybrid configuration appropriate for an unmanned underwater vehicle is explored. A control algorithm was implemented to regulate the power share between the fuel cell and the battery with a graphical interface to control, record and analyze the electrochemical and thermal parameters of the system. The results demonstrate the applicability of the test-bed and control algorithm for this application, and provide data on the dynamic electrical and thermal behaviour of the hybrid system. (author)

Populations of barn swallows (Hirundo rustica) nested seasonally near the Test Reactor Area (TRA) radioactive leaching ponds on the Idaho National Engineering Laboratory. These birds utilized leaching pond arthropods as a food source and contaminated mud for nest construction. Over 20 fission and activation products were detected in immature and adult TRA birds. The radionuclide exhibiting the highest mean concentration in adult birds was 51Cr, with 16.1 Bq g-1. Mean concentrations of detectable radionuclides were used to calculate internal dose rates. Approximately 72% of the total dose rate of 219 microGy d-1 (22 mrad d-1) for adult birds was due to 24Na. Swallow thyroids contained a mean 131I concentration of 3330 Bq g-1. An average dose rate to the thyroid was calculated to be 4300 microGy d-1 or 450 mGy (45 rad) for the entire breeding season. Data from LiF-700 thermoluminescent dosimeters in swallow nests indicated that average dose rates were 840 microGy d-1 for eggs and 2200 Gy d-1 for nestlings, for a total of 54 mGy (5.4 rad) during the nesting period. The breeding biology and growth rate were investigated for TRA swallows and comparison group located 15 km and 100 km away. Total mortality rates for the comparison group vs. 1976 and 1977 TRA populations were not found to be significantly (p greater than 0.9) different. Nonlinear regression was used to fit individual growth curves and estimate parameters using a logistic model. First clutch TRA swallows were found to have a significantly lower mean growth rate compared to either the first clutch comparison group or the second clutch of TRA birds. Mean asymptotic weights achieved by immature TRA birds were also found to be significantly lower than those achieved by comparison group birds. Both growth rate and asymptotic weights for TRA birds were within the normal range reported in the literature

Full Text Available Obiettivo del contributo è quello di proporre alcuni spunti di riflessione sul caso della città di celluloide più nota al mondo: Los Angeles. Più in particolare s’intende analizzare la stretta relazione che intercorre tra l’attrattività turistica della metropoli e l’industria cinematografica.  Come ben noto, Los Angeles continua da quasi un secolo a suggestionare l’immaginario collettivo in quanto mecca del cinema e patria di Hollywood, l’industria che ha creato il sogno americano. Tuttavia LA, oggi, è anche una delle prime dieci città mondiali. Rappresenta l’esempio di come l’industria creativa (e il cinema è creatività per definizione sia riuscita a realizzare un sistema economico e d’innovazione tecnologica che funziona come polo di attrazione sia per tutti coloro che intendono sviluppare nuove attività, non possibili in altre parti del mondo, sia per visitatori e turisti attirati da un insieme di fattori emozionali legati alla notorietà dei luoghi del sistema cinematografico e dello spettacolo. Sulla base dell’analisi della letteratura e facendo seguito a esperienze di studio sul campo, il contributo vuole evidenziare la stretta connessione costruita nel corso di più di un secolo tra Hollywood, il luogo, e Hollywood, l’industria, per dimostrare come il luogo di produzione rappresenti una componente unica del prodotto finale, un’autenticazione di qualità soggettive e simboliche in grado di amplificare il valore economico intrinseco e di provocare un’attrazione crescente di attività e persone verso l’area metropolitana di Los Angeles.   This paper discusses Los Angeles as the best-known celluloid city in the world, and focuses particularly on the close relationship between its attractiveness for tourists and the film industry.

1986-01-01

The term ''Human Reliability Program'' (HRP) is defined as a series of selective controls which are implemented and integrated to identify the ''insider threat'' from current and prospective employees who are dishonest, disloyal and unreliable. The HRP, although not a prediction of human behaviour, is an excellent tool for decision making and should compliment security and improve employee quality. The HRP consists of several component applications such as management evaluation; appropriate background investigative requirements; occupational health examination and laboratory testing; drug/alcohol screening; psychological testing and interviews; polygraph examination; job related aberrant behaviour recognition; on-going education and training; document control; drug/alcohol rehabilitation; periodic HRP audit; and implementation of an onsite central clearing house. The components and effects of HRP are discussed in further detail in this paper

The change of the Helmholtz free energy, internal energy, and entropy accompanying the mixing of acetone and methanol is calculated in the entire composition range by the method of thermodynamic integration using three different potential model combinations of the two compounds. In the first system, both molecules are described by the OPLS, and in the second system, both molecules are described by the original TraPPE force field, whereas in the third system a modified version of the TraPPE potential is used for acetone in combination with the original TraPPE model of methanol. The results reveal that, in contrast with the acetone-water system, all of these three model combinations are able to reproduce the full miscibility of acetone and methanol, although the thermodynamic driving force of this mixing is very small. It is also seen, in accordance with the finding of former structural analyses, that the mixing of the two components is driven by the entropy term corresponding to the ideal mixing, which is large enough to overcompensate the effect of the energy increase and entropy loss due to the interaction of the unlike components in the mixtures. Among the three model combinations, the use of the original TraPPE model of methanol and modified TraPPE model of acetone turns out to be clearly the best in this respect, as it is able to reproduce the experimental free energy, internal energy, and entropy of mixing values within 0.15 kJ/mol, 0.2 kJ/mol, and 1 J/(mol K), respectively, in the entire composition range. The success of this model combination originates from the fact that the use of the modified TraPPE model of acetone instead of the original one in these mixtures improves the reproduction of the entropy of mixing, while it retains the ability of the original model of excellently reproducing the internal energy of mixing.

1982-01-01

The potential of principal components as a pipeline data reduction technique for thematic mapper data was assessed and principal components analysis and its transformation as a noise reduction technique was examined. Two primary factors were considered: (1) how might data reduction and noise reduction using the principal components transformation affect the extraction of accurate spectral classifications; and (2) what are the real savings in terms of computer processing and storage costs of using reduced data over the full 7-band TM complement. An area in central Pennsylvania was chosen for a study area. The image data for the project were collected using the Earth Resources Laboratory's thematic mapper simulator (TMS) instrument.

It gives important information in selecting the appropriate treatment for urolithiasis to confirm the component of urinary calculus. Presently component analysis of the urinary calculus is generally performed by infrared spectroscopy which is employed by companies providing laboratory testing services in Japan. The infrared spectroscopy determines the molecular components from the absorption spectra in consequence of atomic vibrations. It has the drawback that an accurate crystal structure cannot be analyzed compared with the X-ray diffraction method which analyzes the crystal constituent based on the diffraction of X-rays on crystal lattice. The components of the urinary calculus including carbonate are carbonate apatite and calcium carbonate such as calcite. Although the latter is reported to be very rare component in human urinary calculus, the results by infrared spectroscopy often show that calcium carbonate is included in calculus. The infrared spectroscopy can confirm the existence of carbonate but cannot determine whether carbonate is originated from carbonate apatite or calcium carbonate. Thus, it is not clear whether calcium carbonate is included in human urinary calculus component in Japan. In this study, we examined human urinary calculus including carbonate by use of X-ray structural analysis in order to elucidate the origin of carbonate in human urinary calculus. We examined 17 human calculi which were reported to contain calcium carbonate by infrared spectroscopy performed in the clinical laboratory. Fifteen calculi were obtained from urinary tract, and two were from gall bladder. The stones were analyzed by X-ray powder method after crushed finely. The reports from the clinical laboratory showed that all urinary culculi consisted of calcium carbonate and calcium phosphate, while the gallstones consisted of calcium carbonate. But the components of all urinary calculi were revealed to be carbonate apatite by X-ray diffraction. The components of

Nuclear electronics laboratory manual

The Nuclear Electronics Laboratory Manual is a joint product of several electronics experts who have been associated with IAEA activity in this field for many years. The manual does not include experiments of a basic nature, such as characteristics of different active electronics components. It starts by introducing small electronics blocks, employing one or more active components. The most demanding exercises instruct a student in the design and construction of complete circuits, as used in commercial nuclear instruments. It is expected that a student who completes all the experiments in the manual should be in a position to design nuclear electronics units and also to understand the functions of advanced commercial instruments which need to be repaired or maintained. The future tasks of nuclear electronics engineers will be increasingly oriented towards designing and building the interfaces between a nuclear experiment and a computer. The manual pays tribute to this development by introducing a number of experiments which illustrate the principles and the technology of interfacing

Full Text Available In engineering the pedagogical content of most formative programmes includes a significant amount of practical laboratory hands-on activity designed to deliver knowledge acquisition from actual experience alongside traditional face-to-face classroom based lectures and tutorials; this hands-on aspect is not always adequately addressed by current e-learning platforms. An innovative approach to e-learning in engineering, named computer aided engineering education (CAEE is about the use of computer aids for the enhanced, interactive delivery of educational materials in different fields of engineering through two separate but related components; one for classroom and another for practical hands-on laboratory work. The component for hands-on laboratory practical work focuses on the use of mixed reality (video-based augmented reality tools on mobile devices/platforms. This paper presents the computer aided engineering education (CAEE implementation of a laboratory experiment in micro-electronics that highlights some features such as the ability to closely implement an existing laboratory based hands-on experiment with lower associated costs and the ability to conduct the experiment off-line while maintaining existing pedagogical contents and standards.

Polish Code of Ethics of a Medical Laboratory Specialist.

2014-09-01

Along with the development of medicine, increasingly significant role has been played by the laboratory diagnostics. For over ten years the profession of the medical laboratory specialist has been regarded in Poland as the autonomous medical profession and has enjoyed a status of one of public trust. The process of education of medical laboratory specialists consists of a five-year degree in laboratory medicine, offered at Medical Universities, and of a five-year Vocational Specialization in one of the fields of laboratory medicine such as clinical biochemistry, medical microbiology, medical laboratory toxicology, medical laboratory cytomorphology and medical laboratory transfusiology. An important component of medical laboratory specialists' identity is awareness of inherited ethos obtained from bygone generations of workers in this particular profession and the need to continue its further development. An expression of this awareness is among others Polish Code of Ethics of a Medical Laboratory Specialist (CEMLS) containing a set of values and a moral standpoint characteristic of this type of professional environment. Presenting the ethos of the medical laboratory specialist is a purpose of this article. Authors focus on the role CEMLS plays in areas of professional ethics and law. Next, they reconstruct the Polish model of ethos of medical diagnostic laboratory personnel. An overall picture consists of a presentation of the general moral principles concerning execution of this profession and rules of conduct in relations with the patient, own professional environment and the rest of the society. Polish model of ethical conduct, which is rooted in Hippocratic medical tradition, harmonizes with the ethos of medical laboratory specialists of other European countries and the world.

Full Text Available RESUMO: A anemia infecciosa equina (AIE é uma doença causada por um lentivirus que possui distribuição mundial. Essa enfermidade é um entrave ao desenvolvimento da equinocultura no Brasil devido à obrigatoriedade de eutanásia dos animais positivos. Este trabalho teve como objetivo estimar a prevalência de AIE em equídeos de tração no Distrito Federal, assim como identificar fatores de risco associados à doença. Foram sorteados aleatoriamente 350 proprietários (Unidades Primárias de Amostragem- UPA e foram amostrados todos os equídeos (Unidades secundárias de Amostragem de cada proprietário sorteado, totalizando 496 animais. As amostras sanguíneas foram analisadas no Lanagro/MG por meio da técnica de imunodifusão em ágar gel (IDGA. No momento da coleta de sangue, também foi aplicado um questionário epidemiológico para a análise de possíveis fatores de risco. A prevalência de AIE nas UPA foi estimada em 2,29%, (IC 95%: 1,01-4,2% e nos animais foi de 1,81% (IC 95%: 0,55-3,07%. A prevalência foi significativamente maior em muares do que em equinos. Não foi possível comprovar a presença de nenhum outro fator de risco associado à doença. Este estudo demonstra que a prevalência da AIE em equídeos de tração é baixa no Distrito Federal, porém mais alta do que os dados de vigilância de rotina sugerem, o que justifica a eutanásia dos equídeos reagentes, com a finalidade de promover a erradicação da enfermidade. Ratifica-se a importância da realização de exames periódicos nesses animais e a manutenção das atividades de vigilância.

Laboratory Medicine is Faced with the Evolution of Medical Practice

Directory of Open Access Journals (Sweden)

Collinson Paul

2017-09-01

Full Text Available Laboratory medicine and clinical medicine are co-dependent components of medicine. Laboratory medicine functions most effectively when focused through a clinical lens. Me dical practice as a whole undergoes change. New drugs, treatments and changes in management strategies are introduced. New techniques, new technologies and new tests are developed. These changes may be either clinically or laboratory initiated, and so their introduction requires dialogue and interaction between clinical and laboratory medicine specialists. Treatment monitoring is integral to laboratory medicine, varying from direct drug measurement to monitoring cholesterol levels in response to treatment. The current trend to »personalised medicine« is an extension of this process with the development of companion diagnostics. Technological innovation forms part of modern laboratory practice. Introduction of new technology both facilitates standard laboratory approaches and permits introduction of new tests and testing strategies previously confined to the research laboratory only. The revolution in cardiac biomarker testing has been largely a laboratory led change. Flexibility in service provision in response to changing clinical practice or evolving technology provides a significant laboratory management challenge in the light of increasing expectations, shifts in population demographics and constraint in resource availability. Laboratory medicine practitioners are adept at meeting these challenges. One thing remains constant, that there will be a constant need laboratory medicine to meet the challenges of novel clinical challenges from infectious diseases to medical conditions developing from lifestyle and longevity.

Safety analysis report for packaging Lawrence Livermore Laboratories shipping containers

International Nuclear Information System (INIS)

Evans, J.H.

1975-12-01

The Lawrence Livermore Laboratories shipping containers were designed at Oak Ridge National Laboratory for use in transporting weapons and nuclear components. The design for the containers was evaluated to show compliance with applicable regulations governing packages in which radioactive and fissile materials are transported. Computational procedures were used to determine the structural integrity and thermal behavior of the containers relative to the standards for the normal conditions of transport. A full-scale container test model was destructively tested to verify compliance with the standards for the accident conditions. The results of the analytical evaluations and the tests demonstrate that the design for the Lawrence Livermore Laboratories shipping containers is in compliance with the applicable regulations

Consideration of the environmental effects on fatigue behavior of austenitic components. Calculation methods and practical application

Seichter, Johannes; Reese, Sven H.; Klucke, Dietmar

2012-01-01

During the last years environmental effects on the fatigue behavior of nuclear power plant components has worldwide been discussed controversial with respect to the transferability of laboratory data on real components. A publication from Argonne National Laboratory on experimental results concerning environmental effects (air and LWR coolant) on fatigue of austenitic steels included a proposal on calculation methods concerning the lifetime reduction due to environmental effects. This calculation method, i.e. multiplication of the usage factor by a F(en), has been included into the ASME Code, Section III, Division I, as Code Case N-792 (fatigue evaluations including environmental effects). The presented contribution evaluates the practical application of this calculation procedure and demonstrates the determination of the usage factor of an austenitic component under environmental exposure.

Feedforward responses of transversus abdominis are directionally specific and act asymmetrically: implications for core stability theories.

Experimental laboratory study supplemented with a repeated case study. To examine bilateral muscle activity of the deep abdominals in response to rapid arm raising, specifically to examine the laterality and directional specificity of feedforward responses of the transversus abdominis (TrA). Based on the feedforward responses of trunk muscles during rapid arm movements, authors have concluded that the deep trunk muscles have different control mechanisms compared to the more superficial muscles. It has been proposed that deep trunk muscles such as TrA contribute substantially to the stability of the lumbar spine and that this is achieved through simultaneous bilateral feedforward activation. These inferences are based on unilateral fine-wire electromyographic (EMG) data and there are limited investigations of bilateral responses of the TrA during unilateral arm raising. Bilateral fine-wire and surface EMG data from the anterior deltoid, TrA, obliquus internus (OI), obliquus externus, biceps femoris, erector spinae, and rectus abdominis during repeated arm raises were recorded at 2 kHz. EMG signal linear envelopes were synchronized to the onset of the anterior deltoid. A feedforward window was defined as the period up to 50 ms after the onset of the anterior deltoid, and paired onsets for bilateral muscles were plotted for both left and right arm movements. Trunk muscles from the group data demonstrated differences between sides (laterality), which were systematically altered when alternate arms were raised (directional specificity). This was clearly evident for the TrA but less obvious for the erector spinae. The ipsilateral biceps femoris and obliquus externus, and contralateral OI and TrA, were activated earlier than the alternate side for both right and left arm movements. This was a consistent pattern over a 7-year period for the case study. Data for the rectus abdominis derived from the case study demonstrated little laterality or directionally specific

Priest, Michelle

College students must complete a life science course prior to graduation for a bachelor's degree. Generally, the course has lecture and laboratory components. It is in the laboratory where there are exceptional opportunities for exploration, challenge and application of the material learned. Optimally, this would utilize the best of inquiry based approaches. Most community colleges are using a home-grown or self written laboratory manual for the direction of work in the laboratory period. Little was known about the motivation, development and adaptation of use. It was also not known about the future of the laboratory manuals in light of the recent learning reform in California Community Colleges, Student Learning Outcomes. Extensive interviews were conducted with laboratory manual authors to determine the motivation, process of development, who was involved and learning framework used in the creation of the manuals. It was further asked of manual authors their ideas about the future of the manual, the development of staff and faculty and finally, the role Student Learning Outcomes would play in the manual. Science faculty currently teaching the non-majors biology laboratories for at least two semesters were surveyed on-line about actual practice of the manual, assessment, manual flexibility, faculty training and incorporation of Student Learning Outcomes. Finally, an evaluation of the laboratory manual was done using an established Laboratory Task Analysis Instrument. Laboratory manuals were evaluated on a variety of categories to determine the level of inquiry instruction done by students in the laboratory section. The results were that the development of homegrown laboratory manuals was done by community colleges in the Los Angeles and Orange Counties in an effort to minimize the cost of the manual to the students, to utilize all the exercises in a particular lab and to effectively utilize the materials already owned by the department. Further, schools wanted to

Circuit bridging of components by smoke

International Nuclear Information System (INIS)

Tanaka, T.J.; Nowlen, S.P.; Anderson, D.J.

1996-10-01

Smoke can adversely affect digital electronics; in the short term, it can lead to circuit bridging and in the long term to corrosion of metal parts. This report is a summary of the work to date and component-level tests by Sandia National Laboratories for the Nuclear Regulatory Commission to determine the impact of smoke on digital instrumentation and control equipment. The component tests focused on short-term effects such as circuit bridging in typical components and the factors that can influence how much the smoke will affect them. These factors include the component technology and packaging, physical board protection, and environmental conditions such as the amount of smoke, temperature of burn, and humidity level. The likelihood of circuit bridging was tested by measuring leakage currents and converting those currents to resistance in ohms. Hermetically sealed ceramic packages were more resistant to smoke than plastic packages. Coating the boards with an acrylic spray provided some protection against circuit bridging. The smoke generation factors that affect the resistance the most are humidity, fuel level, and burn temperature. The use of CO 2 as a fire suppressant, the presence of galvanic metal, and the presence of PVC did not significantly affect the outcome of these results

Blood tests are some of the core clinical laboratory tests for diagnosing patients. In hospitals, an automated process called total laboratory automation, which relies on a set of sophisticated equipment, is normally adopted for blood tests. Noting that the total laboratory automation system typically requires a large footprint and significant amount of power, slim and easy-to-move blood test equipment is necessary for specific demands such as emergency departments or small-size local clinics. In this article, we present a point-of-care test system that can provide flexibility and portability with low cost. First, the system components, including a reagent tray, dispensing module, microfluidic disk rotor, and photometry scanner, and their functions are explained. Then, a scheduler algorithm to provide a point-of-care test platform with an efficient test schedule to reduce test time is introduced. Finally, the results of diagnostic tests are presented to evaluate the system. © 2014 Society for Laboratory Automation and Screening.

Matsuki, J.; Ikeda, K.; Abe, M. [Kyoto University, Kyoto (Japan)

1996-10-20

This paper describes the results of an experimental study on the characteristics of a thyristor controlled series capacitor (TCSC). At present, there are two major thyristor controlled series compensation projects in the U.S.: the Kayenta ASC and the Slatt TCSC. However, there has been little operating experience and thus further understanding of the characteristics of TCSC is still to be sought. Therefore, a laboratory-scale TCSC was produced and installed in a laboratory power system. The impedance characteristics, waveshapes of voltages and currents in the TCSC circuit, and harmonics, for various thyristor firing angles, and insertion responses were measured and analyzed. In particular, effects of the size of the circuit components, i.e., parasitic resistance, additional damping resistance and series reactor, on the overall TCSC performances were investigated. The results were compared with EMTP simulations. 10 refs., 7 figs.

The authors describe the project undertaken by the Istituto G. Caporale to provide a laboratory information management system (LIMS) to the Central Veterinary Laboratory (CVL) in Windhoek, Namibia. This robust laboratory management tool satisfies Namibia's information obligations under international quality standard ISO 17025:2005. The Laboratory Information Management System (LIMS) for Africa was designed to collect and manage all necessary information on samples, tests and test results. The system involves the entry of sample data on arrival, as required by Namibian sampling plans, the tracking of samples through the various sections of the CVL, the collection of test results, generation of test reports and monitoring of outbreaks through data interrogation functions, eliminating multiple registrations of the same data on paper records. It is a fundamental component of the Namibian veterinary information system.

Fiber optic gyro development at the Jet Propulsion Laboratory

Goss, Willis C.

1987-01-01

A low-level, but continuing, fiber-gyro development activity has been carried on at the Jet Propulsion Laboratory since 1977. The activity was originated because of a recognition of the potential for low-cost high-performance gyros suitable for interplanetary spacecraft. An early decision was made to concentrate available resources on supporting the development of electrooptically active channel waveguide components which could be fabricated by mask diffusion processes. Titanium-indiffused lithium niobate waveguide components used at 0.83 micron wavelength were first tested and then abandoned because of instabilities caused by so-called optical damage. Components fabricated for use at 1.3-micron wavelength have proven to be stable. A gyro configuration concept based upon 1.3 micron channel waveguide components has evolved, and a baseline 1.3-micron all-fiber gyro has been assembled and tested.

The purpose of the project was to develop the processes for using commercial off-the-shelf (COTS) parts for WR production and to put in place a system for implementing the data management tools required to disseminate, store, track procurement, and qualify vendors. Much of the effort was devoted to determining if the use of COTS parts was possible. A basic question: How does the Nuclear Weapons Complex (NWC) begin to use COTS in the weapon Stockpile Life Extension Programs with high reliability, affordability, while managing risk at acceptable levels? In FY00, it was determined that a certain weapon refurbishment program could not be accomplished without the use of COTS components. The elements driving the use of COTS components included decreased cost, greater availability, and shorter delivery time. Key factors that required implementation included identifying the best suppliers and components, defining life cycles and predictions of obsolescence, testing the feasibility of using COTS components with a test contractor to ensure capability, as well as quality and reliability, and implementing the data management tools required to disseminate, store, track procurement, and qualify vendors. The primary effort of this project then was to concentrate on the risks involved in the use of COTS and address the issues of part and vendor selection, procurement and acceptance processes, and qualification of the parts via part and sample testing. The Enterprise Component Information System (eCIS) was used to manage the information generated by the COTS process. eCIS is a common interface for both the design and production of NWC components and systems integrating information between SNL National Laboratory (SNL) and the Kansas City Plant (KCP). The implementation of COTS components utilizes eCIS from part selection through qualification release. All part related data is linked across an unclassified network for access by both SNL and KCP personnel. The system includes not

The purpose of this report is to summarize the activities of the Analytical Chemistry Laboratory (ACL) at Argonne National Laboratory (ANL) for Fiscal Year (FY) 1996. This annual report is the thirteenth for the ACL. It describes effort on continuing and new projects and contributions of the ACL staff to various programs at ANL. The ACL operates in the ANL system as a full-cost-recovery service center, but has a mission that includes a complementary research and development component: The Analytical Chemistry Laboratory will provide high-quality, cost-effective chemical analysis and related technical support to solve research problems of our clients -- Argonne National Laboratory, the Department of Energy, and others -- and will conduct world-class research and development in analytical chemistry and its applications. Because of the diversity of research and development work at ANL, the ACL handles a wide range of analytical chemistry problems. Some routine or standard analyses are done, but the ACL usually works with commercial laboratories if our clients require high-volume, production-type analyses. It is common for ANL programs to generate unique problems that require significant development of methods and adaption of techniques to obtain useful analytical data. Thus, much of the support work done by the ACL is very similar to our applied analytical chemistry research.

Early in his twenty-five year career as the Director of the Los Alamos Scientific Laboratory, Norris Bradbury wrote at length about the atomic bomb and the many implications the bomb might have on the world. His themes were both technical and philosophical. In 1963, after nearly twenty years of leading the nation’s first nuclear weapons laboratory, Bradbury took the opportunity to broaden his writing. In a paper delivered to the International Atomic Energy Agency’s symposium on the “Criteria in the Selection of Sites for the Construction of Reactors and Nuclear Research Centers,” Bradbury took the opportunity to talk about the business of nuclear research and the human component of operating a scientific laboratory. This report is the transcript of his talk.

Full Text Available In this study we compile and present results from the factor analysis of 43 Aerosol Mass Spectrometer (AMS datasets (27 of the datasets are reanalyzed in this work. The components from all sites, when taken together, provide a holistic overview of Northern Hemisphere organic aerosol (OA and its evolution in the atmosphere. At most sites, the OA can be separated into oxygenated OA (OOA, hydrocarbon-like OA (HOA, and sometimes other components such as biomass burning OA (BBOA. We focus on the OOA components in this work. In many analyses, the OOA can be further deconvolved into low-volatility OOA (LV-OOA and semi-volatile OOA (SV-OOA. Differences in the mass spectra of these components are characterized in terms of the two main ions m/z 44 (CO₂⁺ and m/z 43 (mostly C₂H₃O⁺, which are used to develop a new mass spectral diagnostic for following the aging of OA components in the atmosphere. The LV-OOA component spectra have higher f₄₄ (ratio of m/z 44 to total signal in the component mass spectrum and lower f₄₃ (ratio of m/z 43 to total signal in the component mass spectrum than SV-OOA. A wide range of f₄₄ and O:C ratios are observed for both LV-OOA (0.17±0.04, 0.73±0.14 and SV-OOA (0.07±0.04, 0.35±0.14 components, reflecting the fact that there is a continuum of OOA properties in ambient aerosol. The OOA components (OOA, LV-OOA, and SV-OOA from all sites cluster within a well-defined triangular region in the f₄₄ vs. f₄₃ space, which can be used as a standardized means for comparing and characterizing any OOA components (laboratory or ambient observed with the AMS. Examination of the OOA components in this triangular space indicates that OOA component spectra become increasingly similar to each other and to fulvic acid and HULIS sample spectra as f₄₄ (a

Full Text Available Tension (TW and opposite wood (OW of Eucalyptus globulus trees were analyzed for its chemical characteristics and Kraft pulp production. Lignin content was 16% lower and contained 32% more syringyl units in TW than in OW. The increase in syringyl units favoured the formation of β-O-4 bonds that was also higher in TW than in OW (84% vs. 64%, respectively. The effect of these wood features was evaluated in the production of Kraft pulps from both types of wood. At kappa number 16, Kraft pulps obtained from TW demanded less active alkali in delignification and presented slightly higher or similar pulp yield than pulps made with OW. Fiber length, coarseness and intrinsic viscosity were also higher in tension than in opposite pulps. When pulps where refined to 30°SR, TW pulps needed 18% more revolutions in the PFI mill to achieve the same beating degree than OW pulps. Strength properties (tensile, tear and burst indexes were slightly higher or similar in tension as compared with opposite wood pulps. After an OD0(EOD1 bleaching sequence, both pulps achieved up to 89% ISO brightness. Bleached pulps from TW presented higher viscosity and low amount of hexenuronic acids than pulps from OW. Results showed that TW presented high xylans and low lignin content that caused a decrease in alkali consumption, increase pulp strength properties and similar bleaching performance as compared with pulps from OW.Madeira de tração e oposta de árvores de Eucalyptus globulus foram analisadas quanto a suas características químicas e produção de polpa Kraft.

2011-11-01

Full Text Available Participation in diagnostic microbiology internal and external quality control (QC processes is good laboratory practice and an essential component of a quality management system. However, no QC scheme for diagnostic oral microbiology existed until 2009 when the Clinical Oral Microbiology (COMB Network was created. At the European Oral Microbiology Workshop in 2008, 12 laboratories processing clinical oral microbiological samples were identified. All these were recruited to participate into the study and six laboratories from six European countries completed both the online survey and the first QC round. Three additional laboratories participated in the second round. Based on the survey, European oral microbiology laboratories process a significant (mean per laboratory 4,135 number of diagnostic samples from the oral cavity annually. A majority of the laboratories did not participate in any internal or external QC programme and nearly half of the laboratories did not have standard operating procedures for the tests they performed. In both QC rounds, there was a large variation in the results, interpretation and reporting of antibiotic susceptibility testing among the laboratories. In conclusion, the results of this study demonstrate the need for harmonisation of laboratory processing methods and interpretation of results for oral microbiology specimens. The QC rounds highlighted the value of external QC in evaluating the efficacy and safety of processes, materials and methods used in the laboratory. The use of standardised methods is also a prerequisite for multi-centre epidemiological studies that can provide important information on emerging microbes and trends in anti-microbial susceptibility for empirical prescribing in oro-facial infections.

The Risoe National Laboratory of Denmark started as a nuclear research centre, under the Atomic Energy Commission in 1955, with research reactors, an accelerator and related facilities. The research component, aimed at the introduction of nuclear power plants in Denmark, was wound up in 1985 with the country deciding to forego nuclear power in its energy planning. From 1993 the centre is under the jurisdiction of the Ministry of Research with three main areas of work: i) research on high international level; ii) train researchers; and iii) provide service to industry. The centre is funded up to 53% by the Danish Government and 47% by contract earnings. Some areas of current research include: i) materials science; ii) optics and sensor systems; iii) plant production and ecology; and iv) systems analysis. The nuclear component of the research centre is related to the operation of the nuclear facilities and for maintaining national expertise in nuclear safety and radiation protection. (author)

Assessment is a central component of course curriculums and is used to certify student learning, but it can also be used as a tool to improve teaching and learning. Many laboratory courses are structured such that there is only a grade for a particular laboratory, which limits the insights that can be gained in student learning. We developed a…

Measuring meaningful learning in the undergraduate chemistry laboratory

Galloway, Kelli R.

The undergraduate chemistry laboratory has been an essential component in chemistry education for over a century. The literature includes reports on investigations of singular aspects laboratory learning and attempts to measure the efficacy of reformed laboratory curriculum as well as faculty goals for laboratory learning which found common goals among instructors for students to learn laboratory skills, techniques, experimental design, and to develop critical thinking skills. These findings are important for improving teaching and learning in the undergraduate chemistry laboratory, but research is needed to connect the faculty goals to student perceptions. This study was designed to explore students' ideas about learning in the undergraduate chemistry laboratory. Novak's Theory of Meaningful Learning was used as a guide for the data collection and analysis choices for this research. Novak's theory states that in order for meaningful learning to occur the cognitive, affective, and psychomotor domains must be integrated. The psychomotor domain is inherent in the chemistry laboratory, but the extent to which the cognitive and affective domains are integrated is unknown. For meaningful learning to occur in the laboratory, students must actively integrate both the cognitive domain and the affective domains into the "doing" of their laboratory work. The Meaningful Learning in the Laboratory Instrument (MLLI) was designed to measure students' cognitive and affective expectations and experiences within the context of conducting experiments in the undergraduate chemistry laboratory. Evidence for the validity and reliability of the data generated by the MLLI were collected from multiple quantitative studies: a one semester study at one university, a one semester study at 15 colleges and universities across the United States, and a longitudinal study where the MLLI was administered 6 times during two years of general and organic chemistry laboratory courses.

Blood transfusion can be life-saving. Anaesthetists regularly request and administer blood components to their patients. All anaesthetists must be familiar with indications and appropriate use of blood and blood components and their alternatives, but close liaison with haematology specialists and their local blood sciences laboratory is encouraged. Considerable changes in approaches to optimal use of blood components, together with the use of alternative products, have become apparent over the past decade, leading to a need to update previous guidelines and adapt them for the use of anaesthetists working throughout the hospital system. © 2016 The Authors.

Myxobacteria form complex social communities that elicit multicellular behaviors. One such behavior is kin recognition, in which cells identify siblings via their polymorphic TraA cell surface receptor, to transiently fuse outer membranes and exchange their contents. In addition, outer membrane exchange (OME) regulates behaviors, such as inhibition of wild-type Myxococcus xanthus (DK1622) from swarming. Here we monitored the fate of motile cells and surprisingly found they were killed by nonmotile siblings. The kill phenotype required OME (i.e., was TraA dependent). The genetic basis of killing was traced to ancestral strains used to construct DK1622. Specifically, the kill phenotype mapped to a large "polyploid prophage," Mx alpha. Sensitive strains contained a 200-kb deletion that removed two of three Mx alpha units. To explain these results, we suggest that Mx alpha expresses a toxin-antitoxin cassette that uses the OME machinery of M. xanthus to transfer a toxin that makes the population "addicted" to Mx alpha. Thus, siblings that lost Mx alpha units (no immunity) are killed by cells that harbor the element. To test this, an Mx alpha-harboring laboratory strain was engineered (by traA allele swap) to recognize a closely related species, Myxococcus fulvus. As a result, M. fulvus, which lacks Mx alpha, was killed. These TraA-mediated antagonisms provide an explanation for how kin recognition specificity might have evolved in myxobacteria. That is, recognition specificity is determined by polymorphisms in traA, which we hypothesize were selected for because OME with non-kin leads to lethal outcomes. The transition from single cell to multicellular life is considered a major evolutionary event. Myxobacteria have successfully made this transition. For example, in response to starvation, individual cells aggregate into multicellular fruiting bodies wherein cells differentiate into spores. To build fruits, cells need to recognize their siblings, and in part, this is

Hot laboratory at Oarai Research Establishment was founded to examine the objects mainly irradiated at JMTR (Japan Materials Testing Reactor) and has been operated since 1971. A wide variety of post-irradiation examinations (PIE) is available using the hot laboratory. Continuous efforts are made to develop new PIE techniques to accommodate the user's requirements. The following are main techniques recently developed in the hot laboratory; 1. Remote capsule assembly including remote weld of irradiated objects for reirradiation in JMTR. 2. Fracture toughness tests of reactor component materials. 3. Creep tests of heat resistance alloys in high temperature conditions. 4. Tests of irradiation assisted stress corrosion cracking (IASCC). 5. Examination techniques of miniaturized test specimens. This report describes an outline of the hot laboratory with main emphasis on the new PIE techniques. (author)

Systemic Human Anatomy is a full credit, upper year undergraduate course with a (prosection) laboratory component at Western University Canada. To meet enrollment demands beyond the physical space of the laboratory facility, a fully online section was developed to run concurrently with the traditional face to face (F2F) course. Lectures given to F2F students are simultaneously broadcasted to online students using collaborative software (Blackboard Collaborate). The same collaborative software is used by a teaching assistant to deliver laboratory demonstrations in which three-dimensional (3D) virtual anatomical models are manipulated. Ten commercial software programs were reviewed to determine their suitability for demonstrating the virtual models, resulting in the selection of Netter's 3D Interactive Anatomy. Supplementary online materials for the central nervous system were developed by creating 360° images of plastinated prosected brain specimens and a website through which they could be accessed. This is the first description of a fully online undergraduate anatomy course with a live, interactive laboratory component. Preliminary data comparing the online and F2F student grades suggest that previous student academic performance, and not course delivery format, predicts performance in anatomy. Future qualitative studies will reveal student perceptions about their learning experiences in both of the course delivery formats. © 2014 American Association of Anatomists.
