    A sensor array has been developed for use with laboratory automation to permit closed-loop control of liquid levels in a multiwell microplate geometry. We extended a simple electrical model for non-contact capacitance-based fluid sensors to describe a fluid-level dependency. The new model shows that a charge-transfer based capacitance transducer, employing a liquid-specific calibration, can be used to obtain an output signal that varies linearly with the liquid level. The calibration also compensates for liquid-to-liquid conductivity and permittivity differences. A prototype 3×3 sensor array was built and tested using NaCl and ethanol solutions to simulate the range of conductivity and permittivity typical in biological and chemical research. Calibrated output signals were linear with liquid volume for all tested solutions (R2>0.92). Measurement error averaged 1.3 % (2.0 μl) with a standard deviation of 6.0% (9.0 μl). These results demonstrate the feasibility of developing a microvolume sensor array in essentially any M×N microplate geometry. PMID:17281955

    Three-electrode micro-cells equipped with a conventional reference electrode (SCE) were easily constructed based on micro-volume droplets suspended by capillary forces to the fritted glass of the SCE bridge. Working and counter electrodes were simply inserted through the droplet surface, allowing classical electrochemistry to be readily performed in minute samples.

    Full Text Available Analysis methods that require small volumes of aqueous samples can be of large benefit for applications when expensive chemicals are involved or available volumes are substantially small and concentrations are low. A new method is presented to allow microvolume liquid injections on TOC equipment using a special designed Shimadzu gas injection kit® in combination with a high precision syringe and Chaney adapter. Next to details on the methodology of microvolume TOC injections, the technique is shown to be beneficial to evaluate the efficiency of photocatalytic dye degradation on titania materials in terms of CO2 conversion simultaneously with classic UV-Vis analysis measurements within a lab scale photocatalytic test setup (volume <100 mL. The possibility to allow multiple microvolume samplings in short time intervals during several hours without a substantial decrease in volume/catalyst ratio is of particular value for the evaluation of photocatalysts. By combining both techniques at short time intervals, additional knowledge of the degradation process/mechanism, kinetics and the efficiency can be obtained in a direct way. Moreover, the developed μV-TOC analysis is specifically useful in those applications in which low sample volumes in combination with low concentrations are involved. For example, μV-TOC can similarly be put into service in a wide range of small volume setups, e.g., analytes from high-throughput screening, pharmaceutical applications and other advanced oxidation processes that formally could not be analyzed due to limited sample volumes and often low concentrations.

    Self-driven surface micromixers (SDSM) based on patterned wettability technology provide an elegant solution for low-cost point-of-care (POC) devices and lab-on-a-chip (LOC) applications. Our SDSMs are fabricated by strategically patterning three wettable wedge-shaped tracks onto a non-wettable surface. Current state-of-the-art micromixers require energy, however, our SDSMs utilize the inherent surface energy of liquids, coupled with wettability contrast to efficiently mix small amounts of liquids (e.g. droplets). Transport and mixing of the SDSMs is accomplished by means of Laplace pressure-driven flow and several mixing approaches, such as splitting-recombining, stretching-folding, and transversal vortices. Mixing is initiated when separate liquid micro-volumes are transported along respective, juxtaposed wettable tracks. As the liquid micro-volumes coalesce, subsequent mixing occurs during transport of the combined volume over a third separate wettable track that also features a non-wettable ``island.'' The two-dimensional island disrupts the flow of liquids, in a similar manner a three-dimensional obstacle would, thus generating the aforementioned mixing enhancement. Several SDSMs, each having different island geometries, were investigated, giving rise to a greater understanding of efficient mixing on surfaces. The study offers a design basis for developing a low-cost surface microfluidic mixing device on various substrates.

  6. Headspace single-drop microextraction coupled to microvolume UV-vis spectrophotometry for iodine determination

    International Nuclear Information System (INIS)

    Headspace single-drop microextraction has been combined with microvolume UV-vis spectrophotometry for iodine determination. Matrix separation and preconcentration of iodide following in situ volatile iodine generation and extraction into a microdrop of N,N'-dimethylformamide is performed. An exhaustive characterization of the microextraction system and the experimental variables affecting iodine generation from iodide was carried out. The procedure employed consisted of exposing 2.5 μL of N,N'-dimethylformamide to the headspace of a 10 mL acidic (H2SO4 2 mol L-1) aqueous solution containing 1.7 mol L-1 Na2SO4 for 7 min. Addition of 1 mL of H2O2 1 mol L-1 for in situ iodine generation was performed. The limit of detection was determined as 0.69 μg L-1. The repeatability, expressed as relative standard deviation, was 4.7% (n = 6). The calibration working range was from 5 to 200 μg L-1 (r2 = 0.9991). The large preconcentration factor obtained, ca. 623 in only 7 min, compensate for the 10-fold loss in sensitivity caused by the decreased optical path, which results in improved detection limits as compared to spectrophotometric measurements carried out with conventional sample cells. The method was successfully applied to the determination of iodine in water, pharmaceutical and food samples

    The ATLAS Experiment has conducted a search for the rare decays of Bs and Bd into mu+mu-. 25 fb−1 of integrated luminosity of proton-proton collisions collected during LHC Run 1 were studied and new results were obtained, as presented in this talk. An upper limit is set on the Bd to mu+mu- branching ratio of BR(Bd to mu+mu-) < 4.2×10−10 at 95% confidence level. For Bs, ATLAS measurement yields the branching ratio BR(Bs to mu+mu-)=(0.9+1.1−0.8)×10−9. The result is consistent with the Standard Model expectation and other available measurements.

  10. The pulsating extreme helium star BD + 1303224

    International Nuclear Information System (INIS)

    Ultraviolet flux variations are reported for the pulsating extreme helium star BD + 1303224 (V652 Her). Effective temperature and angular radius variations over a cycle are determined from static plane-parallel LTE model atmospheres. When compared with radius changes derived from ground-based spectroscopy, the angular radius variations indicate radial pulsations and correspond to a distance of 1.5 +- 0.1 kpc. BD + 1303224 is thought to be a helium-burning star of 0.7 Msolar masses, which has an envelope contracting as the helium-burning core grows; it is similar to HD 144941 and these two stars may constitute a new sub-class of the hydrogen-deficient stars.

    Full Text Available Utility vectors with promoters that confer desired spatial and temporal expression patterns are useful tools for studying gene and cellular function and for industrial applications. To target the expression of DNA sequences of interest to cells forming plant secondary cell walls, which generate most of the vegetative biomass, upstream regulatory sequences of the Brachypodium distachyon lignin biosynthetic gene BdPMT and the cellulose synthase genes BdCESA7 and BdCESA8 were isolated and cloned into binary vectors designed for Agrobacterium-mediated transformation of monocots. Expression patterns were assessed using the β-glucuronidase gene GUSPlus and X-glucuronide staining. All three promoters showed strong expression levels in stem tissue at the base of internodes where cell wall deposition is most active, in both vascular bundle xylem vessels and tracheids, and in interfascicular tissues, with expression less pronounced in developmentally older tissues. In leaves, BdCESA7 and BdCESA8 promoter-driven expression was strongest in leaf veins, leaf margins, and trichomes; relatively weaker and patchy expression was observed in the epidermis. BdPMT promoter-driven expression was similar to the BdCESA promoters expression patterns, including strong expression in trichomes. The intensity and extent of GUS staining varied considerably between transgenic lines, suggesting that positional effects influenced promoter activity. Introducing the BdPMT and BdCESA8 Open Reading Frames (ORFs into BdPMT and BdCESA8 utility promoter binary vectors, respectively, and transforming those constructs into Brachypodium pmt and cesa8 loss-of-function mutants resulted in rescue of the corresponding mutant phenotypes. This work therefore validates the functionality of these utility promoter binary vectors for use in Brachypodium and likely other grass species.

  13. Widespread occurrence of bd in French Guiana, South America.

    The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) is a purported agent of decline and extinction of many amphibian populations worldwide. Its occurrence remains poorly documented in many tropical regions, including the Guiana Shield, despite the area's high amphibian diversity. We conducted a comprehensive assessment of Bd in French Guiana in order to (1) determine its geographical distribution, (2) test variation of Bd prevalence among species in French Guiana and compare it to earlier reported values in other South American anuran species (http://www.bd-maps.net; 123 species from 15 genera) to define sentinel species for future work, (3) track changes in prevalence through time and (4) determine if Bd presence had a negative effect on one selected species. We tested the presence of Bd in 14 species at 11 sites for a total of 1053 samples (306 in 2009 and 747 in 2012). At least one Bd-positive individual was found at eight out of 11 sites, suggesting a wide distribution of Bd in French Guiana. The pathogen was not uniformly distributed among the studied amphibian hosts, with Dendrobatidae species displaying the highest prevalence (12.4%) as compared to Bufonidae (2.6 %) and Hylidae (1.5%). In contrast to earlier reported values, we found highest prevalence for three Dendrobatidae species and two of them displayed an increase in Bd prevalence from 2009 to 2012. Those three species might be the sentinel species of choice for French Guiana. For Dendrobates tinctorius, of key conservation value in the Guiana Shield, smaller female individuals were more likely to be infected, suggesting either that frogs can outgrow their chytrid infections or that the disease induces developmental stress limiting growth. Generally, our study supports the idea that Bd is more widespread than previously thought and occurs at remote places in the lowland forest of the Guiana shield.

    Full Text Available   Time-dependent wormhole solution of the BD theory in an anisotropic radiation background is presented. It is also found that the BD scalar field depends only on time. This time dependency is in power-law form. It is shown that the wormhole geometry is valid for ω ≥ -3/2, and for any arbitrary positive values of . The GR limit of our solution is obtained for ω=0 , not for ω→∞ . Though the BD field can be non-exotic, the background material is entirely exotic.

  16. Saudi production capacity climbing to 10 million b/d

    International Nuclear Information System (INIS)

    Saudi Arabia this year is completing its expansion of production capacity and developing recent discoveries to enhance export flexibility. The 3 million b/d capacity expansion to 10 million b/d, announced in 1989, is on target for completion by year end 1994. Most of the effort involves restoration of mothballed production equipment and installation of several gas-oil separation plants (GOSPs) in existing fields. But Saudi Arabian Oil Co. (Saudi Aramco) also this year will start up production of extra-light oil from a new field in the central part of the kingdom. Start-up of Hawtah area production demonstrates success of an oil search Aramco began after receiving exclusive exploration rights to nearly all of Saudi Arabia's prospective area in 1986. From new fields and traditional producing areas, therefore, Saudi Arabia has the potential to expand production capacity beyond 10 million b/d. The paper describes the development of the extra capacity

    Full Text Available Influenza (flu pandemics have exhibited a great threat to human health throughout history. With the emergence of drug-resistant strains of influenza A virus (IAV, it is necessary to look for new agents for treatment and transmission prevention of the flu. Defensins are small (2–6 kDa cationic peptides known for their broad-spectrum antimicrobial activity. Beta-defensins (β-defensins are mainly produced by barrier epithelial cells and play an important role in attacking microbe invasion by epithelium. In this study, we focused on the anti-influenza A virus activity of mouse β-defensin 1 (mBD1 and β defensin-3 (mBD3 by synthesizing their fusion peptide with standard recombinant methods. The eukaryotic expression vectors pcDNA3.1(+/mBD1-mBD3 were constructed successfully by overlap-PCR and transfected into Madin-Darby canine kidney (MDCK cells. The MDCK cells transfected by pcDNA3.1(+/mBD1-mBD3 were obtained by G418 screening, and the mBD1-mBD3 stable expression pattern was confirmed in MDCK cells by RT-PCR and immunofluorescence assay. The acquired stable transfected MDCK cells were infected with IAV (A/PR/8/34, H1N1, 0.1 MOI subsequently and the virus titers in cell culture supernatants were analyzed by TCID50 72 h later. The TCID50 titer of the experimental group was clearly lower than that of the control group (p < 0.001. Furthermore, BALB/C mice were injected with liposome-encapsulated pcDNA3.1(+/mBD1-mBD3 through muscle and then challenged with the A/PR/8/34 virus. Results showed the survival rate of 100% and lung index inhibitory rate of 32.6% in pcDNA3.1(+/mBD1-mBD3group; the TCID50 titer of lung homogenates was clearly lower than that of the control group (p < 0.001. This study demonstrates that mBD1-mBD3 expressed by the recombinant plasmid pcDNA3.1(+/mBD1-mBD3 could inhibit influenza A virus replication both in vitro and in vivo. These observations suggested that the recombinant mBD1-mBD3 might be developed into an agent for

    A classification spectrum of BD +60 73, reported to be the optical counterpart to IGR J00370+6122 (ATel #281), was taken on the night of 2003 July 7th with the 2.5-m Issac Newton telescope at La Palma. The derived spectral type is BN0.5II-III, where the composite luminosity class indicates an intermediate luminosity. The Nitrogen enhancement is moderately high, with numerous NII lines being rather stronger than corresponds to the spectral type.

  1. A Gamma Doradus Candidate In Eclipsing Binary BD And?

    2013-01-01

    The BVR photometric light curves of the eclipsing binary BD And were obtained in 2008 and 2009. We estimated the mass ratio of the system as 0.97 and the photometric solutions were derived. The results show that BD And is a detached binary system, whose components have a little temperature difference of about 40 K. By analyzing photometric available light minimum times, we also derived an update ephemeris and found for the first time a possible periodic oscillation with an amplitude of 0.011 days and a period of 9.6 years. The results indicate that the periodic oscillation could be caused by a third component physically attached to the eclipsing binary. After removing the light variations due to the eclipses and proximity effects, the light-curve distortions are further explained by the pulsation of the primary component with a dominant period of 1 day. In accordance with the position of the primary component on the Hertzsprung-Russell diagram and its pulsation period, the primary component of BD And could be...

    We have developed microvolume EMIT procedures for theophylline, phenobarbital, phenytoin, carbamazepine, primidone, ethosuximide, and gentamicin using a centrifugal analyzer (CentrifiChem and Pipettor 1000) to reduce the manufacturer's recommended manual reagent consumption by one-sixth. In addition to developing the EMIT procedure, the performance of the analyzer and pipettor were verified. The analyzer and pipettor are capable of producing within-run precision at a 3-microliters sample volume and 210-microliters analyzer cuvette volume equal to or less than 1.5%. The performance of the EMIT procedures on the analyzer yielded spike drug recoveries of 90.8 to 106.1% for drug concentrations throughout the calibration concentration range of each assay. The percent error on standard reference material of the National Bureau of Standards ranged from a +12.0% to a -0.6% for ethosuximide, phenobarbital, phenytoin, and primidone. Patient comparison data yielded slopes from 0.930 to 1.110 for all assays. The other important feature of the adapted EMIT assay is its simplicity for use on a routine basis.

    Biological production of 2,3-butandiol (2,3-BD) has received great attention as an alternative to the petroleum-based 2,3-BD production. In this study, a high production of 2,3-BD in fed-batch fermentation was investigated with a newly isolated bacterium designated as Raoultella ornithinolytica B6. The isolate produced 2,3-BD as the main product using hexoses (glucose, galactose, and fructose), pentose (xylose) and disaccharide (sucrose). The effects of temperature, pH-control schemes, and agitation speeds on 2,3-BD production were explored to optimize the fermentation conditions. Notably, cell growth and 2,3-BD production by R. ornithinolytica B6 were higher at 25°C than at 30°C. When three pH control schemes (no pH control, pH control at 7, and pH control at 5.5 after the pH was decreased to 5.5 during fermentation) were tested, the best 2,3-BD titer and productivity along with reduced by-product formation were achieved with pH control at 5.5. Among different agitation speeds (300, 400, and 500 rpm), the optimum agitation speed was 400 rpm with 2,3-BD titer of 68.27 g/L, but acetic acid was accumulated up to 23.32 g/L. Further enhancement of the 2,3-BD titer (112.19 g/L), yield (0.38 g/g), and productivity (1.35 g/L/h) as well as a significant reduction of acetic acid accumulation (9.71 g/L) was achieved by the overexpression of homologous budABC genes, the 2,3-BD-synthesis genes involved in the conversion of pyruvate to 2,3-BD. This is the first report presenting a high 2,3-BD production by R.ornithinolytica which has attracted little attention with respect to 2,3-BD production, extending the microbial spectrum of 2,3-BD producers.

    International Nuclear Information System (INIS)

    The authors present a study of heavy flavor tagging using soft lepton identification. They optimize their soft lepton identification method for use in a time-dependent Bd mixing measurement. In events triggered by a high Pt lepton from one B hadron, they search for a soft lepton from the semileptonic decay of the other B hadron. The charge of each lepton tags the flavor of its parent B hadron at the time of that parent's decay. The authors present the resulting efficiency and dilution for their optimized method

    A novel approach is presented, whereby gold nanostructured screen-printed carbon electrodes (SPCnAuEs) are combined with in-situ ionic liquid formation dispersive liquid-liquid microextraction (in-situ IL-DLLME) and microvolume back-extraction for the determination of mercury in water samples. In-situ IL-DLLME is based on a simple metathesis reaction between a water-miscible IL and a salt to form a water-immiscible IL into sample solution. Mercury complex with ammonium pyrrolidinedithiocarbamate is extracted from sample solution into the water-immiscible IL formed in-situ. Then, an ultrasound-assisted procedure is employed to back-extract the mercury into 10 µL of a 4 M HCl aqueous solution, which is finally analyzed using SPCnAuEs. Sample preparation methodology was optimized using a multivariate optimization strategy. Under optimized conditions, a linear range between 0.5 and 10 µg L(-1) was obtained with a correlation coefficient of 0.997 for six calibration points. The limit of detection obtained was 0.2 µg L(-1), which is lower than the threshold value established by the Environmental Protection Agency and European Union (i.e., 2 µg L(-1) and 1 µg L(-1), respectively). The repeatability of the proposed method was evaluated at two different spiking levels (3 and 10 µg L(-1)) and a coefficient of variation of 13% was obtained in both cases. The performance of the proposed methodology was evaluated in real-world water samples including tap water, bottled water, river water and industrial wastewater. Relative recoveries between 95% and 108% were obtained. PMID:25640123

    A growing body of evidence shows that gamma-hydroxybutyric acid (GHB) is an addictive substance. Its precursors gammabutyrolactone (GBL) and 1,4-butanediol (1,4-BD) show the same properties and may pose even more risks due to different pharmacokinetics. There are indications that problematic GHB use is increasing in the European Union. This review investigates the existing literature on the neurochemistry of GHB and its precursors, their acute toxicity, addiction potential and withdrawal, the proposed molecular mechanism underlying addiction and the treatment of withdrawal and addiction. Current evidence shows that GHB and its precursors are highly addictive, both in humans and animals, probably through a GABAB receptor related mechanism. Severity of withdrawal symptoms can be considered as a medical emergency. Recent studies suggest that benzodiazepines are not very effective, showing a high treatment resistance, whereas detoxification with pharmaceutical GHB proved to be successful. However, relapse in GHB use is frequent and more research is warranted on relapse prevention. This might aid medical practitioners in the field and improve general understanding of the severity of addiction to GHB, GBL and 1,4-BD.

The aim of this thesis was to explore the alternative hypothesis that such growth depressions are caused by Pi limitation under conditions where a repressed direct Pi uptake in AM plants is not fully compensated by the AM-mediated Pi uptake. The hypothesized relationship between P...... limitation and growth depression was investigated by manipulation of the transcript levels of BdPT4 and BdPT8, two putative direct Brachypodium distachyon phosphate transporters (BdPT). Using a reverse genetic transformation approach, over-expression (OE) lines and knock-down (RNAi) lines of each BdPT gene...... be involved in uptake of Pi via the AM pathway, which correlates with the slightly decreased AM-mediated uptake in BdPT4-RNAi plants. Since mitigation of AM-related growth depression was not achieved by OE of the assumed direct uptake pathway transporter genes BdPT4 and BdPT8, the alternative hypothesis...

    2013-09-01

    Full Text Available Introduction: Defensins are small anti-microbial peptides produced by epithelial cells. These peptides have a broad range of actions against microorganisms, including Gram-positive and Gram-negative bacteria.Human defensins are classifi ed into two subfamilies, the α-, and β- defensins, which differ in their distribution of disulphide bonds between the six conserved cysteine residues. Defensins are found in salivaand others compartments of the body. Human β defensins 2 (hBD2, beta defensins 4 (hBD4 and alpha defensins 4 (hNP4 in saliva may contributes to vulnerability or resistance to caries. This study aimed to determine a possible correlation between caries and levels of defensins measuring the expression in gingival tissue and concentrations in saliva samples.Methods: Oral examinations were performed on 100 adults of both genders (18-30 years old, and unstimulated whole saliva was collected for immunoassays of the three peptides and for the salivary pH, buffercapacity, protein, and peroxidase activity. mRNA levels of defensins in gingival sample were assessed by semi-quantitative RT-PCR technique.Results: The median salivary levels of hBD2 and hBD4 were 1.88 μg/ml and 0.86 μg/ml respectively for the caries-free group (n=44 and 7.26 μ/ml (hBD2 and 4.25 μg/ml (hBD4 for all subjects with evidenceof caries (n=56. There was no difference in the levels of hNP4, salivary pH, and proteins between groups, however the peroxidase activity and buffer capacity (interval 6.0-5.0 were reduced in caries group. Transcriptional levels of hBD2 and hBD4 did correlate with caries experience, the mRNA expression of hBD2 and hBD4 were signifi cantly higher in patients with caries than in patients with no-caries (p < 0.01.Conclusion: We conclude that high salivary levels and expression of beta defensins, low peroxidase activity and buffer capacity may represent a biological response of oral tissue to caries. Our observation couldlead to new ways to prevent

  11. The Cytochrome bd Oxidase of Porphyromonas gingivalis Contributes to Oxidative Stress Resistance and Dioxygen Tolerance.

    Full Text Available Porphyromonas gingivalis is an etiologic agent of periodontal disease in humans. The disease is associated with the formation of a mixed oral biofilm which is exposed to oxygen and environmental stress, such as oxidative stress. To investigate possible roles for cytochrome bd oxidase in the growth and persistence of this anaerobic bacterium inside the oral biofilm, mutant strains deficient in cytochrome bd oxidase activity were characterized. This study demonstrated that the cytochrome bd oxidase of Porphyromonas gingivalis, encoded by cydAB, was able to catalyse O2 consumption and was involved in peroxide and superoxide resistance, and dioxygen tolerance.

BDQ was instantly bactericidal against a cytochrome bd oxidase null mutant of M. tuberculosis, and the rate of killin...

  17. Nuclear hBD-1 accumulation in malignant salivary gland tumours

    International Nuclear Information System (INIS)

    Whereas the antimicrobial peptides hBD-2 and -3 are related to inflammation, the constitutively expressed hBD-1 might function as 8p tumour suppressor gene and thus play a key role in control of transcription and induction of apoptosis in malignant epithelial tumours. Therefore this study was conducted to characterise proteins involved in cell cycle control and host defence in different benign and malignant salivary gland tumours in comparison with healthy salivary gland tissue. 21 paraffin-embedded tissue samples of benign (n = 7), and malignant (n = 7) salivary gland tumours as well as healthy (n = 7) salivary glands were examined immunohistochemically for the expression of p53, bcl-2, and hBD-1, -2, -3. HBD-1 was distributed in the cytoplasm of healthy salivary glands and benign salivary gland tumours but seems to migrate into the nucleus of malignant salivary gland tumours. Pleomorphic adenomas showed cytoplasmic as well as weak nuclear hBD-1 staining. HBD-1, 2 and 3 are traceable in healthy salivary gland tissue as well as in benign and malignant salivary gland tumours. As hBD-1 is shifted from the cytoplasm to the nucleus in malignant salivary gland tumours, we hypothesize that it might play a role in the oncogenesis of these tumours. In pleomorphic adenomas hBD-1 might be connected to their biologic behaviour of recurrence and malignant transformation

    2013-03-01

    Full Text Available The historical circumstances of Guillem Fabre’s two surviving sirventes has given rise to widely divergent views. This essay builds on Parducci’s contextualisation of BdT 216.2 during the War of the Sicilian Vespers and the so-called Aragonese crusade by the French against Pere III of Aragon in 1284-1285. It argues that Guillem is likely to be referring to events say entre nos because Narbonne was the focal point of the gathering French army and preaching of the crusade. All other textual details are compatible with this period and best explained by this context. But while Parducci places the sirventes in May 1285, it must in fact have preceded the death of Martin IV on 29 March, since his speedily-appointed successor Honorius IV could not be blamed for not having preached a crusade against the heathen before the conflict degenerated into further atrocities. Furthermore a slightly earlier timing better explains the allusion to “the best-known man in the world”, the obvious candidate at this time being Charles of Anjou. Guillem probably composed BdT 216.2 during the build-up to war in 1284, before the death of Charles in January 1285, during the period of war preparations and propaganda speeches. It is also argued here that, pace Parducci, BdT 216.1 did not necessarily precede BdT 216.2.

    2011-04-01

    Full Text Available Abstract Background Studies in bipolar disorder (BD to date are limited in their ability to provide a whole-disease perspective - their scope has generally been confined to a single disease phase and/or a specific treatment. Moreover, most clinical trials have focused on the manic phase of disease, and not on depression, which is associated with the greatest disease burden. There are few longitudinal studies covering both types of patients with BD (I and II and the whole course of the disease, regardless of patients' symptomatology. Therefore, the Wide AmbispectiVE study of the clinical management and burden of Bipolar Disorder (WAVE-bd (NCT01062607 aims to provide reliable information on the management of patients with BD in daily clinical practice. It also seeks to determine factors influencing clinical outcomes and resource use in relation to the management of BD. Methods WAVE-bd is a multinational, multicentre, non-interventional, longitudinal study. Approximately 3000 patients diagnosed with BD type I or II with at least one mood event in the preceding 12 months were recruited at centres in Austria, Belgium, Brazil, France, Germany, Portugal, Romania, Turkey, Ukraine and Venezuela. Site selection methodology aimed to provide a balanced cross-section of patients cared for by different types of providers of medical aid (e.g. academic hospitals, private practices in each country. Target recruitment percentages were derived either from scientific publications or from expert panels in each participating country. The minimum follow-up period will be 12 months, with a maximum of 27 months, taking into account the retrospective and the prospective parts of the study.

    Full Text Available Paenibacillus spp. BD3526, a bacterium exhibiting a protein hydrolysis circle surrounded with an obvious precipitation zone on skim milk agar, was isolated from raw yak (Bos grunniens milk collected in Tibet, China. Phylogenetic analysis based on 16S rRNA and whole genome sequence comparison indicated the isolate belong to the genus Paenibacillus. The strain BD3526 demonstrated strong ability to produce protease with milk clotting activity (MCA in wheat bran broth. The protease with MCA was predominantly accumulated during the late-exponential phase of growth. The proteolytic activity (PA of the BD3526 protease was 1.33-fold higher than that of the commercial R. miehei coagulant. A maximum MCA (6470 ± 281 SU mL−1 of the strain BD3526 was reached under optimal cultivation conditions. The protease with MCA was precipitated from the cultivated supernatant of wheat bran broth with ammonium sulfate and purified by anion-exchange chromatography. The molecular weight of the protease with MCA was determined as 35 kDa by sodium dodecyl sulfate-polyacrylamide gels electrophoresis (SDS-PAGE and gelatin zymography. The cleavage site of the BD3526 protease with MCA in κ-casein was located at the Met106–Ala107 bond, as determined by mass spectrometry analysis.

  1. Redox control of fast ligand dissociation from Escherichia coli cytochrome bd

    International Nuclear Information System (INIS)

    Bacterial bd-type quinol oxidases, such as cytochrome bd from Escherichia coli, contain three hemes, but no copper. In contrast to heme-copper oxidases and similarly to globins, single electron-reduced cytochrome bd forms stable complexes with O2, NO and CO at ferrous heme d. Kinetics of ligand dissociation from heme d 2+ in the single electron- and fully-reduced cytochrome bd from E. coli has been investigated by rapid mixing spectrophotometry at 20 oC. Data show that (i) O2 dissociates at 78 s-1 (ii) NO and CO dissociation is fast as compared to heme-copper oxidases and (iii) dissociation in the single electron-reduced state is hindered as compared to the fully-reduced enzyme. Presumably, rapid ligand dissociation requires reduced heme b 595. As NO, an inhibitor of respiratory oxidases, is involved in the immune response against microbial infection, the rapid dissociation of NO from cytochrome bd may have important bearings on the patho-physiology of enterobacteria

    Hydrogen sulfide (H2S) impairs mitochondrial respiration by potently inhibiting the heme-copper cytochrome c oxidase. Since many prokaryotes, including Escherichia (E.) coli, generate H2S and encounter high H2S levels particularly in the human gut, herein we tested whether bacteria can sustain sulfide-resistant O2-dependent respiration. E. coli has three respiratory oxidases, the cyanide-sensitive heme-copper bo3 enzyme and two bd oxidases much less sensitive to cyanide. Working on the isolated enzymes, we found that, whereas the bo3 oxidase is inhibited by sulfide with half-maximal inhibitory concentration IC50 = 1.1 ± 0.1 μM, under identical experimental conditions both bd oxidases are insensitive to sulfide up to 58 μM. In E. coli respiratory mutants, both O2-consumption and aerobic growth proved to be severely impaired by sulfide when respiration was sustained by the bo3 oxidase alone, but unaffected by ≤200 μM sulfide when either bd enzyme acted as the only terminal oxidase. Accordingly, wild-type E. coli showed sulfide-insensitive respiration and growth under conditions favouring the expression of bd oxidases. In all tested conditions, cyanide mimicked the functional effect of sulfide on bacterial respiration. We conclude that bd oxidases promote sulfide-resistant O2-consumption and growth in E. coli and possibly other bacteria. The impact of this discovery is discussed. PMID:27030302

    Full Text Available BD-Func (BiDirectional FUNCtional enrichment is an algorithm that calculates functional enrichment by comparing lists of pre-defined genes that are known to be activated versus inhibited in a pathway or by a regulatory molecule. This paper shows that BD-Func can correctly predict cell line alternations and patient characteristics with accuracy comparable to popular algorithms, with a significantly faster run-time. BD-Func can compare scores for individual samples across multiple groups as well as provide predictive statistics and receiver operating characteristic (ROC plots to quantify the accuracy of the signature associated with a binary phenotypic variable. BD-Func facilitates collaboration and reproducibility by encouraging users to share novel molecular signatures in the BD-Func discussion group, which is where the novel progesterone receptor and LBH589 signatures from this paper can be found. The novel LBH589 signature presented in this paper also serves as a case study showing how a custom signature using cell line data can accurately predict activity in vivo.

    Based on the finding of a novel berberine (BBR)-utilizing bacterium, Rhodococcus sp. strain BD7100, we investigated the degradation of BBR and its analog berberrubine (BRU). Resting cells of BD7100 demethylenated BBR and BRU, yielding benzeneacetic acid analogs. Isolation of benzeneacetic acid analogs suggested that BD7100 degraded the isoquinoline ring of the protoberberine skeleton. This work represents the first report of cleavage of protoberberine skeleton by a microorganism. PMID:26882131

    We measure the branching ratio of the purely leptonic decay of the D+ meson with unprecedented precision as B(D+ -> mu+ nu) = (3.82 +/- 0.32 +/- 0.09)x10^(-4), using 818/pb of data taken on the psi(3770) resonance with the CLEO-c detector at the CESR collider. We use this determination to derive a value for the pseudoscalar decay constant fD+, combining with measurements of the D+ lifetime and assuming |Vcd| = |Vus|. We find fD+ = (205.8 +/- 8.5 +/- 2.5) MeV. The decay rate asymmetry [B(D+ -> mu+ nu)-B(D- -> mu- nu)]/[B(D+ -> mu+ nu)+B(D- -> mu- nu)] = 0.08 +/- 0.08, consistent with no CP violation. We also set 90% confidence level upper limits on B(D+ -> tau+ nu) e+ nu) < 8.8x10^(-6).

    Background The BD FACSPresto™ Near-Patient CD4 Counter was developed to expand HIV/AIDS management in resource-limited settings. It measures absolute CD4 counts (AbsCD4), percent CD4 (%CD4), and hemoglobin (Hb) from a single drop of capillary or venous blood in approximately 23 minutes, with throughput of 10 samples per hour. We assessed the performance of the BD FACSPresto system, evaluating accuracy, stability, linearity, precision, and reference intervals using capillary and venous blood at KEMRI/CDC HIV-research laboratory, Kisumu, Kenya, and precision and linearity at BD Biosciences, California, USA. Methods For accuracy, venous samples were tested using the BD FACSCalibur™ instrument with BD Tritest™ CD3/CD4/CD45 reagent, BD Trucount™ tubes, and BD Multiset™ software for AbsCD4 and %CD4, and the Sysmex™ KX-21N for Hb. Stability studies evaluated duration of staining (18–120-minute incubation), and effects of venous blood storage <6–24 hours post-draw. A normal cohort was tested for reference intervals. Precision covered multiple days, operators, and instruments. Linearity required mixing two pools of samples, to obtain evenly spaced concentrations for AbsCD4, total lymphocytes, and Hb. Results AbsCD4 and %CD4 venous/capillary (N = 189/ N = 162) accuracy results gave Deming regression slopes within 0.97–1.03 and R2 ≥0.96. For Hb, Deming regression results were R2 ≥0.94 and slope ≥0.94 for both venous and capillary samples. Stability varied within 10% 2 hours after staining and for venous blood stored less than 24 hours. Reference intervals results showed that gender—but not age—differences were statistically significant (p<0.05). Precision results had <3.5% coefficient of variation for AbsCD4, %CD4, and Hb, except for low AbsCD4 samples (<6.8%). Linearity was 42–4,897 cells/μL for AbsCD4, 182–11,704 cells/μL for total lymphocytes, and 2–24 g/dL for Hb. Conclusions The BD FACSPresto system provides accurate, precise clinical

  10. Folding Behaviour for Proteins BBL and E3BD with Gō-like Models

    @@ Folding behaviour of protein BBL and its homologue domain E3BD are studied by using an off-lattice Gō-like model. It is found that the folding behaviours of these two proteins are different. Protein BBL folds in a downhill manner, which is consistent with experiments. In contrast, protein E3BD folds cooperatively and has a bimodal distribution of the Q values (the similarity to the native state). By analysing the native structures of the two proteins, it is found that the difference in folding behaviours can be attributed to the different structural features described by the number of nonlocal contacts per residue.

    2011-01-01

    Abstract Background Studies in bipolar disorder (BD) to date are limited in their ability to provide a whole-disease perspective - their scope has generally been confined to a single disease phase and/or a specific treatment. Moreover, most clinical trials have focused on the manic phase of disease, and not on depression, which is associated with the greatest disease burden. There are few longitudinal studies covering both types of patients with BD (I and II) and the whole course of the disea...

    Defensins are frontline peptides of mucosal immunity in the animal kingdom, including birds. Their resistance to proteolysis and their ensuing ability to maintain antimicrobial potential remains questionable and was therefore investigated. We have shown by bottom-up mass spectrometry analysis of protein extracts that both avian beta-defensins AvBD2 and AvBD7 were ubiquitously distributed along the chicken gut. Cathepsin B was found by immunoblotting in jejunum, ileum, caecum, and caecal tonsils, while cathepsins K, L, and S were merely identified in caecal tonsils. Hydrolysis product of AvBD2 and AvBD7 incubated with a panel of proteases was analysed by RP-HPLC, mass spectrometry and antimicrobial assays. AvBD2 and AvBD7 were resistant to serine proteases and to cathepsins D and H. Conversely cysteine cathepsins B, K, L, and S degraded AvBD2 and abolished its antibacterial activity. Only cathepsin K cleaved AvBD7 and released Ile4-AvBD7, a N-terminal truncated natural peptidoform of AvBD7 that displayed antibacterial activity. Besides the 3-stranded antiparallel beta-sheet typical of beta-defensins, structural analysis of AvBD7 by two-dimensional NMR spectroscopy highlighted the restricted accessibility of the C-terminus embedded by the N-terminal region and gave a formal evidence of a salt bridge (Asp9-Arg12) that could account for proteolysis resistance. The differential susceptibility of avian defensins to proteolysis opens intriguing questions about a distinctive role in the mucosal immunity against pathogen invasion. PMID:27561012

    Bromodomains are epigenetic readers that specifically bind to the acetyl lysine residues of histones and transcription factors. Small molecule BET bromodomain inhibitors can disrupt this interaction which leads to potential modulation of several disease states. Here we describe the binding properties of a novel BET inhibitor RVX-297 that is structurally related to the clinical compound RVX-208, currently undergoing phase III clinical trials for the treatment of cardiovascular diseases, but is distinctly different in its biological and pharmacokinetic profiles. We report that RVX-297 preferentially binds to the BD2 domains of the BET bromodomain and Extra Terminal (BET) family of protein. We demonstrate the differential binding modes of RVX-297 in BD1 and BD2 domains of BRD4 and BRD2 using X-ray crystallography, and describe the structural differences driving the BD2 selective binding of RVX-297. The isothermal titration calorimetry (ITC) data illustrate the related differential thermodynamics of binding of RVX-297 to single as well as dual BET bromodomains. PMID:27282480

    The BD+40\\degree4124 region was observed with high angular and spectral resolution with the German heterodyne instrument GREAT in CO J = 13 \\rightarrow 12 and [CII] on SOFIA. These observations show that the [CII] emission is very strong in the reflection nebula surrounding the young Herbig Ae/Be star BD+40\\degree4124. A strip map over the nebula shows that the [CII] emission approximately coincides with the optical nebulosity. The strongest [CII] emission is centered on the B2 star and a deep spectrum shows that it has faint wings, which suggests that the ionized gas is expanding. We also see faint CO J = 13 \\rightarrow 12 at the position of BD+40\\degree4124, which suggests that the star may still be surrounded by an accretion disk.We also detected [CII] emission and strong CO J = 13 \\rightarrow 12 toward V1318 Cyg. Here the [CII] emission is fainter than in BD+40\\degree4124 and appears to come from the outflow, since it shows red and blue wings with very little emission at the systemic velocity, where the C...

    We report on Spitzer Space Telescope Infrared Array Camera observations of near-Earth object 2009 BD that were carried out in support of the NASA Asteroid Robotic Retrieval Mission concept. We did not detect 2009 BD in 25 hr of integration at 4.5 μm. Based on an upper-limit flux density determination from our data, we present a probabilistic derivation of the physical properties of this object. The analysis is based on the combination of a thermophysical model with an orbital model accounting for the non-gravitational forces acting upon the body. We find two physically possible solutions. The first solution shows 2009 BD as a 2.9 ± 0.3 m diameter rocky body (ρ = 2.9 ± 0.5 g cm{sup –3}) with an extremely high albedo of 0.85{sub −0.10}{sup +0.20} that is covered with regolith-like material, causing it to exhibit a low thermal inertia (Γ=30{sub −10}{sup +20} SI units). The second solution suggests 2009 BD to be a 4 ± 1 m diameter asteroid with p{sub V}=0.45{sub −0.15}{sup +0.35} that consists of a collection of individual bare rock slabs (Γ = 2000 ± 1000 SI units, ρ=1.7{sub −0.4}{sup +0.7} g cm{sup –3}). We are unable to rule out either solution based on physical reasoning. 2009 BD is the smallest asteroid for which physical properties have been constrained, in this case using an indirect method and based on a detection limit, providing unique information on the physical properties of objects in the size range smaller than 10 m.

  18. Characterization of Young measures generated by sequences in BV an BD

    CERN Document Server

    Rindler, Filip

    2011-01-01

    First, this work presents a new and improved proof strategy for the recent characterization theorem for generalized Young measures generated by sequences in BV by Kristensen and the author [Arch. Ration. Mech. Anal. 197 (2010), 539-598]. The present proof is based on a localization technique together with a rigidity argument and avoids employing a relaxation theorem. Then, based on this new technique, we prove an analogous characterization result for Young measures generated by sequences in the space BD of functions of bounded deformation. This theorem places these Young measures in duality to symmetric-quasiconvex functions. For this purpose we need to strengthen a recent rigidity result for BD-functions and their associated tangent Young measures, which is also interesting in its own right. Finally, as an application of the characterization theorem, we show how for Young measures with an "atomic" part one can find a generating sequence respecting this structure.

    The Boiling Water Reactor (BWR) version of the Transient Reactor Analysis Code (TRAC) is being developed at the Idaho National Engineering Laboratory (INEL) to provide an advanced best-estimate predictive capability for the analysis of postulated accidents in BWRs. The TRAC-BD1 program provides the Loss of Coolant Accident (LOCA) analysis capability for BWRs and for many BWR related thermal hydraulic experimental facilities. This code features a three-dimensional treatment of the BWR pressure vessel; a detailed model of a BWR fuel bundle including multirod, multibundle, radiation heat transfer, leakage path modeling capability, flow-regime-dependent constitutive equation treatment, reflood tracking capability for both falling films and bottom flood quench fronts, and consistent treatment of the entire accident sequence. The BWR component models in TRAC-BD1 are described and comparisons with data presented. Application of the code to a BWR6 LOCA is also presented.

    2010-01-01

    We present a new analysis of kinematic data of the young planetary nebula BD+30 3639. The data include spectroscopic long-slit and internal proper motion measurements. In this paper we also introduce a new type of mapping of kinematic proper motion data that we name "criss-cross" mapping. It basically consists of finding all points where extended proper motion vectors cross converge. From the crossing points a map is generated which helps to interpret the kinematic data. From the criss-cross mapping of BD+30 3639, we conclude that the kinematic center is approximately 0.5 arcsec offset to the South-East from the central star. The mapping does also show evidence for a non-homologous expansion of the nebula that is consistent with a disturbance aligned with the bipolar molecular bullets.

    2009-01-01

    We investigate the sum capacity of Block Diagonalization precoding Multiple Input Multiple Output Broadcast Channels (BD MIMO BC) with imperfect Channel State Information (CSI) at the base station. Since it is difficult to obtain the exact expression, a lower and an upper bounds of the sum capacity under Gaussian channel estimation errors are drived instead. Analyses show that the gap between two bounds is considerably tight at all Signal to Noise Ratio (SNR) region. From the lower bound of the sum capacity, we can see that the multiplexing gain tends to be zero at high SNR region, which indicates that the BD MIMO BC system with channel estimation errors is interference-limited at high SNR.

  2. A revised ephemeris for the pulsating hydrogen-deficient star BD + 130 3224 (V652 Her)

    International Nuclear Information System (INIS)

    Additional observations of maxima of the pulsating hydrogen-deficient star, BD + 130 3224 (V652 Her), give an improved ephemeris for the decreasing period of pulsation. A simple quadratic no longer appears sufficient and a cubic solution may be preferable, indicating that the pulsation decrease rate is slowing down as the star contracts. An alternative hypotheses, that the star is a binary is also discussed. (author)

    In 60 inverse-pb of data taken on the psi(3770) resonance with the CLEO-c detector, we find 8 D+ -> mu+ nu decay candidates that are mostly signal, containing only 1 estimated background. Using this statistically compelling sample, we measure a value of B(D+ -> mu+ nu) = (3.5 +/- 1.4 +/- 0.6) x10^(-4), and determine fD+=(202 +/- 41 +/-17) MeV.

    This study was conducted to enhance flavor characteristics of wine by malolactic fermentation using recombinant Pediococcus acidilactici BD16 (fcs (+)/ech (+)) encoding synthetic genes of feruloyl-CoA synthetase and enoyl-CoA hydratase. After malolactic fermentation, wine phenolics were characterized using LCMS-ESI technique and a significant improvement in the antioxidant activity and flavor characteristics of wine was observed due to increased concentration of cinnamic acid derivatives. This proof of concept study highlights the role of recombinant P. acidilactici BD16 (fcs (+)/ech (+)) in improving flavor as well as aroma of wine due to production of several phenolic derivatives during secondary fermentation. A novel metabolic pathway was predicted from mass spectral analysis data that indicates biotransformation of cinnamic acid and derivatives into apigenin, catechin, coniferyl aldehyde, cyanidin, hydroxybenzoic acids, laricitrin, luteolin, malvidin 3-glucoside, myricetin, naringenin, pelargonin, piceatannol, querecitin, and vanillin that not only increased the overall consumer appreciation but also improved nutritional and probably the therapeutic properties of wines. This is a first evidence-based study where role of recombinant P. acidilactici BD16 (fcs (+)/ech (+)) in the wine secondary fermentation has been elucidated. PMID:25650327

    2014-01-01

    Pulsed X-ray emission in the luminous, helium-rich sdO BD+37 442 has recently been discovered (La Palombara et al., 2012). It was suggested that the sdO star has a neutron star or white dwarf companion with a spin period of 19.2 s. After HD 49798, which has a massive white dwarf companion spinning at 13.2 s in an 1.55 day orbit, this is only the second O-type subdwarf from which X-ray emission has been detected. We report preliminary results of our ongoing campaign to obtain time-resolved high-resolution spectroscopy using the CAFE instrument at Calar Alto observatory and SARG at the Telescopio Nationale Galileo. Atmospheric parameters were derived via a quantitative NLTE spectral analysis. The line fits hint at an unusually large projected rotation velocity. Therefore it seemed likely that BD+37 442 is a binary similar to HD 49798 and that the orbital period is also similar. The level of X-ray emission from BD+37 442 could be explained by accretion from the sdO wind by a neutron star orbiting at a period of ...

    This note includes a measurement of the $B^0_s$ decay parameters in the $ B_s \\rightarrow J/\\psi$ channel and a measurement of the $B_d$ meson using the statistics collected by the ATLAS experiment in Run I of the LHC.

    This study demonstrated that an automated version of the BD-GeneOhm methicillin-resistant Staphylococcus aureus (MRSA) assay (BD-MRSA), using achromopeptidase sample lysis and PCR setup performed on the Hamilton MICROLAB STARlet (Auto-MRSA), gave results comparable to those obtained with BD-MRSA. The positive- and negative-result concordance rates and overall concordance of BD-MRSA and Auto-MRSA were 98.2, 97.7, and 97.6%, respectively. Auto-MRSA required 60% less technical time than BD-MRSA,...

    A levan-producing strain, BD1707, was isolated from Tibetan kefir and identified as Leuconostoc citreum. The effects of carbon sources on the growth of L. citreum BD1707 and levan production in tomato juice were measured. The changes in pH, viable cell count, sugar content, and levan yield in the cultured tomato juice supplemented with 15% (wt/vol) sucrose were also assayed. L. citreum BD1707 could synthesize more than 28 g/liter of levan in the tomato juice-sucrose medium when cultured at 30°C for 96 h. Based on the monosaccharide composition, molecular mass distribution, Fourier transform infrared (FTIR) spectra, and nuclear magnetic resonance (NMR) spectra, the levan synthesized by L. citreum BD1707 was composed of a linear backbone consisting of consecutive β-(2→6) linked d-fructofuranosyl units, with an estimated average molecular mass of 4.3 × 10(6) Da.

    beta-Defensins are mammalian antimicrobial peptides that share a unique disulfide-bonding motif of six conserved cysteines. An intragenic polymorphism of the DEFB1 gene that changes a highly conserved Cys to Ser in the peptide coding region has recently been described. The deduced peptide cannot form three disulfide bonds, as one of the cysteines is unpaired. We have determined the cysteine connectivities of a corresponding synthetic hBD-1(Ser35) peptide, investigated the structure by circular dichroism spectroscopy, and assayed the in vitro antimicrobial activity. Despite a different arrangement of the disulfides, hBD-1(Ser35) proved as active as hBD-1 against the microorganisms tested. This activity likely depends on the ability of hBD-1(Ser35) to adopt an amphipathic conformation in hydrophobic environment, similar to the wild type peptide, as suggested by CD spectroscopy.

    Trichomonas vaginalis is the most prevalent nonviral sexually transmitted infection worldwide, and improved diagnostic methods are critical for controlling this pathogen. Diagnostic assays that can be used in conjunction with routine chlamydia/gonorrhea nucleic acid-based screening are likely to have the most impact on disease control. Here we describe the performance of the new BD T. vaginalis Qx (TVQ) amplified DNA assay, which can be performed on the automated BD Viper system. We focus on data from vaginal swab samples, since this is the specimen type routinely used for traditional trichomonas testing and the recommended specimen type for chlamydia/gonorrhea screening. Vaginal swabs were obtained from women attending sexually transmitted disease or family planning clinics at 7 sites. Patient-collected vaginal swabs were tested by the TVQ assay, and the Aptima T. vaginalis (ATV) assay was performed using clinician-collected vaginal swabs. Additional clinician-collected vaginal swabs were used for the wet mount and culture methods. Analyses included comparisons versus the patient infection status (PIS) defined by positive results with the wet mount method or culture, direct comparisons assessed with κ scores, and latent class analysis (LCA) as an unbiased estimator of test accuracy. Data from 838 women, 116 of whom were infected with T. vaginalis, were analyzed. The TVQ assay sensitivity and specificity estimates based on the PIS were 98.3% and 99.0%, respectively. The TVQ assay was similar to the ATV assay (κ=0.938) in direct analysis. LCA estimated the TVQ sensitivity and specificity as 98.3 and 99.6%, respectively. The TVQ assay performed well using self-collected vaginal swabs, the optimal sample type, as recommended by the CDC for chlamydia/gonorrhea screening among women. PMID:24391200

  11. Use of the BD-100R as a neutron spectrometer through applied pressure variation

    A study was undertaken to demonstrate the feasibility of using the well-characterized BD-100R neutron bubble dosimeter as a neutron spectrometer in low-level radiation fields. The BD-100R dosimeters used in this work consisted of a test tube containing an elastic polymer with interspersed droplets of two types of Freon: Freon-12 and Freon-114. Each superheated liquid droplet is a potential nucleation site, with the minimum energy needed to form a bubble at the nucleation site being inversely proportional to the square of the difference between the applied and the vapor pressure (i.e., Emin alpha(delta P)-2). For a given dose, the number of bubbles formed continually decreases with increasing applied pressure, until a pressure is reached where no bubbles are formed, since the energy transferred can no longer vaporize the Freon. This investigation is intended to demonstrate the feasibility of measuring an unknown spectrum utilizing the dosimeter response (number of bubbles formed) as a function of the neutron energy (applied pressure). A set of 12 dosimeters was exposed under various applied pressures in a well-characterized neutron energy spectrum at the East Beam Port (EBP) of the Maryland University Training Reactor (MUTR). The dosimeters were placed inside a pressure chamber that could accommodate up to 18 dosimeters. Energy response coefficients (cross-sections) were obtained by spectral unfolding techniques on the known spectrum. The same set of dosimeters were then irradiated using a paraffin-moderated Pu/Be source. Measured spectral estimates obtained using the response coefficients were compared with numerical computations generated using the ANISN computer code. The results indicate that further research using the BD-100R as a neutron spectrometer in low radiation fields is warranted.

    Full Text Available Bifidobacteria, one of the relatively dominant components of the human intestinal microbiota, are considered one of the key groups of beneficial intestinal bacteria (probiotic bacteria. However, in addition to health-promoting taxa, the genus Bifidobacterium also includes Bifidobacterium dentium, an opportunistic cariogenic pathogen. The genetic basis for the ability of B. dentium to survive in the oral cavity and contribute to caries development is not understood. The genome of B. dentium Bd1, a strain isolated from dental caries, was sequenced to completion to uncover a single circular 2,636,368 base pair chromosome with 2,143 predicted open reading frames. Annotation of the genome sequence revealed multiple ways in which B. dentium has adapted to the oral environment through specialized nutrient acquisition, defences against antimicrobials, and gene products that increase fitness and competitiveness within the oral niche. B. dentium Bd1 was shown to metabolize a wide variety of carbohydrates, consistent with genome-based predictions, while colonization and persistence factors implicated in tissue adhesion, acid tolerance, and the metabolism of human saliva-derived compounds were also identified. Global transcriptome analysis demonstrated that many of the genes encoding these predicted traits are highly expressed under relevant physiological conditions. This is the first report to identify, through various genomic approaches, specific genetic adaptations of a Bifidobacterium taxon, Bifidobacterium dentium Bd1, to a lifestyle as a cariogenic microorganism in the oral cavity. In silico analysis and comparative genomic hybridization experiments clearly reveal a high level of genome conservation among various B. dentium strains. The data indicate that the genome of this opportunistic cariogen has evolved through a very limited number of horizontal gene acquisition events, highlighting the narrow boundaries that separate commensals from

  13. Planetary Systems Around Spectroscopic Binary Stars: The Very Dusty, Old, Sun-like BD+20 307

    Field star BD+20 307 is the dustiest known main sequence star, based on the fraction of its bolometric luminosity, 4%, emitted at infrared wavelengths (Song et al. 2005; Rhee et al. 2008). The temperature of the particles that carry this large IR luminosity is comparable to that of the Sun's zodiacal dust, and their existence is likely a consequence of a fairly recent collision of large objects such as planets or planetary embryos. BD+20 307 is now known to be a 3.4 day spectroscopic binary composed of two nearly equal solar-mass stars (Weinberger 2008; Zuckerman et al. 2008). Consideration of various age indicators implies that that star is likely to be at least one Gyr old, perhaps many Gyr old. Probably the dust around this close binary star has nothing to do with planet formation and everything to do with some major catastrophic event that recently took place near 1 AU in a mature planetary system. Destabilizing planetary orbits in an old system with a single star at its center appears to be possible, e.g., Mercury (Batygin & Laughlin 2008 and references therein). Destabilization may be easier to achieve in a close binary star system and easier yet in a triple star system. Tokovinin et al. (2006) conclude that, for a spectroscopic binary star with an orbital period of 3.4 days, the probability is 70% that a third star is present. Thus, we have searched for such a tertiary star in the BD+20 307 system using accurate radial velocities measured at Fairborn and Lick observatories and with adaptive optics imaging at Keck observatory. As of the writing of this abstract, no third star is detected. Limits on mass and semimajor axis of any tertiary star will be discussed. This research was supported by a grant from the Chandra X-ray Observatory.

    2015-07-01

    Immunolocalization of mannans in the seeds of Brachypodium distachyon reveals the presence of these polysaccharides in the root embryo and in the coleorhiza in the early stages of germination (12h), decreasing thereafter to the point of being hardly detected at 27h. Concurrently, the activity of endo-β-mannanases (MANs; EC 3.2.1.78) that catalyse the hydrolysis of β-1,4 bonds in mannan polymers, increases as germination progresses. The MAN gene family is represented by six members in the Brachypodium genome, and their expression has been explored in different organs and especially in germinating seeds. Transcripts of BdMAN2, BdMAN4 and BdMAN6 accumulate in embryos, with a maximum at 24-30h, and are detected in the coleorhiza and in the root by in situ hybridization analyses, before root protrusion (germination sensu stricto). BdMAN4 is not only present in the embryo root and coleorhiza, but is abundant in the de-embryonated (endosperm) imbibed seeds, while BdMAN2 and BdMAN6 are faintly expressed in endosperm during post-germination (36-42h). BdMAN4 and BdMAN6 transcripts are detected in the aleurone layer. These data indicate that BdMAN2, BdMAN4 and BdMAN6 are important for germination sensu stricto and that BdMAN4 and BdMAN6 may also influence reserve mobilization. Whether the coleorhiza in monocots and the micropylar endosperm in eudicots have similar functions, is discussed.

    Two-body charmless nonleptonic decays of B_u and B_d mesons are studied within the framework of generalized factorization in which the effective Wilson coefficients $c^{eff}_i$ are renormalization-scale and -scheme independent while factorization is applied to the tree-level hadronic matrix elements. Contrary to previous studies, our $c_i^{eff}$ do not suffer from gauge and infrared problems. Nonfactorizable effects are parametrized in terms of N_c(LL) and N_c(LR), the effective numbers of co...

    Full Text Available Jofre de Foixa’s verses “Subrafusa ab cabirol” (BdT 304.4 merit attention for the light the two ‘coblas’ shed on Jofre’s familiarity with his Occitan predecessors, for the information the text provides regarding food practices in his time, and for the use of a food term rare in the Iberian peninsula, “unyo”. The resources of culinary history, specifically fourteenth- and fifteenth-century Languedocian and Catalan cookbooks, allow us better to understand the meaning of Jofre’s lyric.

  18. On the period of the pulsating hydrogen-deficient star BD + 1303224

    International Nuclear Information System (INIS)

    Recent observations of maxima of the pulsating early-type hydrogen-deficient star BD + 1303224 indicate a decrease in period since the discovery observations. The data are best fitted by a decrease rate of 46 x 10-10 day cycle, a value which is comparable with the rate derived from a theoretical study of the fast evolutionary phase of a post-giant helium star. Four-colour data are averaged to give mean colours at 0.1 phase intervals around the pulsation cycle. (author)

    Context. Spectral analyses of hot, compact stars with non-local thermodynamical equilibrium (NLTE) model-atmosphere techniques allow the precise determination of photospheric parameters such as the effective temperature (Teff), the surface gravity (log g), and the chemical composition. The derived photospheric metal abundances are crucial constraints for stellar evolutionary theory. Aims: Previous spectral analyses of the exciting star of the nebula A 35, BD-22°3467, were based on He+C+N+O+Si+Fe models only. For our analysis, we use state-of-the-art fully metal-line blanketed NLTE model atmospheres that consider opacities of 23 elements from hydrogen to nickel. We aim to identify all observed lines in the ultraviolet (UV) spectrum of BD-22°3467 and to determine the abundances of the respective species precisely. Methods: For the analysis of high-resolution and high signal-to-noise ratio (S/N) far-ultraviolet (FUSE) and UV (HST/STIS) observations, we combined stellar-atmosphere models and interstellar line-absorption models to fully reproduce the entire observed UV spectrum. Results: The best agreement with the UV observation of BD-22°3467 is achieved at Teff = 80 ± 10 kK and log g = 7.2 ± 0.3. While Teff of previous analyses is verified, log g is significantly lower. We re-analyzed lines of silicon and iron (1/100 and about solar abundances, respectively) and for the first time in this star identified argon, chromium, manganese, cobalt, and nickel and determined abundances of 12, 70, 35, 150, and 5 times solar, respectively. Our results partially agree with predictions of diffusion models for DA-type white dwarfs. A combination of photospheric and interstellar line-absorption models reproduces more than 90% of the observed absorption features. The stellar mass is M ≈ 0.48 M⊙. Conclusions.BD-22°3467 may not have been massive enough to ascend the asymptotic giant branch and may have evolved directly from the extended horizontal branch to the white dwarf

  2. Effect of hBD2 genetically modified dermal multipotent stem cells on repair of infected irradiated wounds

    International Nuclear Information System (INIS)

    Deficiencies in repair cells and infection are two of the main factors that can hinder the process of wound healing. In the present study, we investigated the ability of human beta-defensin-2 (hBD2) genetically modified dermal multipotent stem cells (dMSCs) to accelerate the healing irradiated wounds complicated by infections. An hBD2 adenovirus expression vector (Adv-hBD2) was firstly constructed and used to infect dMSCs. The antibacterial activity of the supernatant was determined by Kirby-Bauer method and macrodilution broth assay. Time to complete wound healing, residual percentage of wound area, and the number of bacteria under the scar were measured to assess the effects of Adv-hBD2-infected dMSC transplantation on the healing of irradiated wounds complicated by Pseudomonas aeruginosa infection. Results showed that the supernatant from Adv-hBD2-infected dMSCs had obvious antibacterial effects. Transplantation of Adv-hBD2-infected dMSCs killed bacteria in the wound. The complete wound healing time was 19.8±0.45 days, which was significantly shorter than in the control groups (P<0.05). From 14 days after transplantation, the residual wound area was smaller in the experimental group than in the control groups (P<0.05). In conculsion, we found that transplantation of hBD2 genetically modified dMSCs accelerated the healing of wounds complicated by P. aeruginosa infection in whole body irradiated rats. (author)

  4. Re (epsilon'/epsilon_K) vs. B_d -> phi K_S CP asymmetry

    2005-01-01

    In a SUSY GUT seesaw scenario, the largeness of the atmospheric neutrino mixing can reflect itself into an enhanced flavor changing mixing of beauty and strange right-handed scalar quarks. If the CP violating phase in such down type squark RR insertion is the main source of CP asymmetry in B_d -> phi K_S and the gluino contributions to K0-K0 bar and B0-B0 bar mixing are negligible, there is a correlation between Re (epsilon'/epsilon_K) and B_d -> phi K_S CP asymmetry, in addition to that with the strange quark CEDM. The current data on Re (epsilon'/epsilon_K) = (16.7 +- 2.6) 10^-4 imply that S_{phi K} should be greater than \\sim 0.5 (0.25) for mu tan beta = 1 (5) TeV, assuming the RR dominance in b -> s transition and the minimal supergravity type boundary conditions for soft parameters.

    Full Text Available Web contents related to educational institutions as well as their geographic data of a country is an emerging field of data sharing and consolidating with suitable data repositories to extract useful information to improve and maintain the area-based quality of education. The information of these institutions is available in the unstructured or semi-structured format from heterogeneous sources on the web that originate challenges to develop a smarter method in finding specific information using traditional search engines. The integration of these heterogeneous data along with geographic information is a formidable task to explore implicit knowledge of educational institutions that assist people to improve these systems and it is still getting researchers’ attention. In this regard, our research demonstrates the feasibility of semantic web technologies for converting and integrating these unstructured or semistructured information by introducing machine understandable description of resources and instances by consisting of their concepts and relations, called a repository name EduBD. This yields a magnificent knowledge graph with .75 million nodes, i.e. RDF triples to facilitate reasoning meaningful information by a graph based query language SPARQL. Furthermore, we utilized our knowledge-base EduBD with one more accessible spatial data source Geo-Bangladesh using Physical-Cyber-Social computing approach to examine spatial contents and social information of each institution and therefore achieved the semantic interoperability of our Linked Open Data (LOD application by eliminating natural language polisemy problems.

    2016-01-01

    The carbon-enhanced metal-poor star BD+44 493 ([Fe/H]=-3.9) has been proposed as a candidate second-generation star enriched by metals from a single Pop III star. We report the first detections of P and S and the second detection of Zn in any extremely metal-poor carbon-enhanced star, using new spectra of BD+44 493 collected by the Cosmic Origins Spectrograph on the Hubble Space Telescope. We derive [P/Fe]=-0.34 +/- 0.21, [S/Fe]=+0.07 +/- 0.41, and [Zn/Fe]=-0.10 +/- 0.24. We increase by ten-fold the number of Si I lines detected in BD+44 493, yielding [Si/Fe]=+0.15 +/- 0.22. The solar [S/Fe] and [Zn/Fe] ratios exclude the hypothesis that the abundance pattern in BD+44 493 results from depletion of refractory elements onto dust grains. Comparison with zero-metallicity supernova models suggests that the stellar progenitor that enriched BD+44 493 was massive and ejected much less than 0.07 Msun of Ni-56, characteristic of a faint supernova.

  7. Cytochrome bd-I in Escherichia coli is less sensitive than cytochromes bd-II or bo′' to inhibition by the carbon monoxide-releasing molecule, CORM-3☆☆☆

    Background: CO-releasing molecules (CO-RMs) are potential therapeutic agents, able to deliver CO – a critical gasotransmitter – in biological environments. CO-RMs are also effective antimicrobial agents; although the mechanisms of action are poorly defined, haem-containing terminal oxidases are primary targets. Nevertheless, it is clear from several studies that the effects of CO-RMs on biological systems are frequently not adequately explained by the release of CO: CO-RMs are generally more potent inhibitors than is CO gas and other effects of the molecules are evident. Methods: Because sensitivity to CO-RMs cannot be predicted by sensitivity to CO gas, we assess the differential susceptibilities of strains, each expressing only one of the three terminal oxidases of E. coli — cytochrome bd-I, cytochrome bd-II and cytochrome bo′, to inhibition by CORM-3. We present the first sensitive measurement of the oxygen affinity of cytochrome bd-II (Km 0.24 μM) employing globin deoxygenation. Finally, we investigate the way(s) in which thiol compounds abolish the inhibitory effects of CORM-2 and CORM-3 on respiration, growth and viability, a phenomenon that is well documented, but poorly understood. Results: We show that a strain expressing cytochrome bd-I as the sole oxidase is least susceptible to inhibition by CORM-3 in its growth and respiration of both intact cells and membranes. Growth studies show that cytochrome bd-II has similar CORM-3 sensitivity to cytochrome bo′. Cytochromes bo′ and bd-II also have considerably lower affinities for oxygen than bd-I. We show that the ability of N-acetylcysteine to abrogate the toxic effects of CO-RMs is not attributable to its antioxidant effects, or prevention of CO targeting to the oxidases, but may be largely due to the inhibition of CO-RM uptake by bacterial cells. Conclusions: A strain expressing cytochrome bd-I as the sole terminal oxidase is least susceptible to inhibition by CORM-3. N-acetylcysteine is a

Analysis of the spectrum confirms a T-shaped equilibrium geometry for the B+-D2 complex with a vibrationally averaged intermolecular bond length of 2.247 Å, around 0.02 Å shorter than for the previously characterised B+-H2 complex [V. Dryza, B. L. J. Poad, and E. J. Bieske, J. Am. Chem. Soc. 130, 12986 (2008), 10.1021/ja8018302]. The D-D stretch band centre occurs at 2839.76 ± 0.10 cm-1, representing a -153.8 cm-1 shift from the Q1(0) transition of the free D2 molecule. A new three dimensional ab initio potential energy surface for the B++H2 interaction is calculated using the coupled cluster RCCSD(T) method and is used in variational calculations for the rovibrational energies of B+-H2 and B+-D2. The calculations predict dissociation energies of 1254 cm-1 for B+-H2 with respect to the B++H2 (j = 0) limit, and 1313 cm-1 for B+-D2 with respect to the B++D2 (j = 0) limit. The theoretical approach reproduces the rotational and centrifugal constants of the B+-H2 and B+-D2 complexes to within 3%, and the magnitude of the contraction of the intermolecular bond accompanying excitation of the H2 or D2 sub-unit, but underestimates the H-H and D-D vibrational band shifts by 7%-8%. Combining the theoretical and experimental results allows a new, more accurate estimation for the B+-H2 band origin (3939.64 ± 0.10 cm-1).

  11. Spectroscopic evidence for a heme-heme binuclear center in the cytochrome bd ubiquinol oxidase from Escherichia coli.

    OpenAIRE

    Hill, J J; Alben, J O; Gennis, R B

    1993-01-01

    The cytochrome bd complex is a ubiquinol oxidase, which is part of the aerobic respiratory chain of Escherichia coli. This enzyme is structurally unrelated to the heme-Cu oxidases such as cytochrome c oxidase. While the cytochrome bd complex contains no copper, it does have three heme prosthetic groups: heme b558, heme b595, and heme d (a chlorin). Heme b558 appears to be involved in the oxidation of quinol, and heme d is known to be the site where oxygen binds and is reduced to water. The ro...

    Two-body charmless nonleptonic decays of B_u and B_d mesons are studied within the framework of generalized factorization in which the effective Wilson coefficients $c^{eff}_i$ are renormalization-scale and -scheme independent while factorization is applied to the tree-level hadronic matrix elements. Contrary to previous studies, our $c_i^{eff}$ do not suffer from gauge and infrared problems. Nonfactorizable effects are parametrized in terms of N_c(LL) and N_c(LR), the effective numbers of colors arising from (V-A)(V-A) and (V-A)(V+A) four-quark operators, respectively. Tree and penguin transitions are classified into six different classes. The data of $B^-\\to\\rho^0\\pi^-$ and $B^-\\to\\phi K^-$ clearly indicate that $N_c(LR)\

    2016-01-01

    Search for deviations from the standard model is performed in the systems of the neutral B mesons. The Bs system is studied in the decay into J/psi phi. The mixing phase phi_s and the width difference DeltaGamma_s are determined through the simultaneous study of angular distributions in the final state and of the decay time, performed together with flavour tagging at production. The measurement performed by ATLAS with the full LHC Run-1 sample is discussed and compared to the previous world average. The width difference DeltaGamma_d in the Bd system is obtained from the comparison of the decay time distributions in the flavour specific state J/psi K* and in the CP eigenstate J/psi KS. The result obtained from the full sample of data collected by ATLAS at 7 and 8 TeV is the most accurate single measurement of the width difference currently available.

  14. Molecular line formation in the extremely metal-poor star BD+44 493

    Molecular absorption lines of OH (99 lines) and CH (105 lines) are measured for the carbon-enhanced metal-poor star BD+44 493 with [Fe/H]=-3.8. The abundances of oxygen and carbon determined from individual lines based on an 1D-LTE analysis exhibit significant dependence on excitation potentials of the lines; d log e/d chi ~ -0.15 - -0.2 dex/eV, where e and chi are elemental abundances from individual spectral lines and their excitation potentials, respectively. The dependence is not explained by the uncertainties of stellar parameters, but suggests that the atmosphere of this object possesses a cool layer that is not reproduced by the 1D model atmosphere. This result agrees with the predictions by 3D model calculations. Although absorption lines of neutral iron exhibit similar trend, it is much weaker than found in molecular lines and that predicted by 3D LTE models.

  15. PHOTOIONIZATION MODELS OF THE INNER GASEOUS DISK OF THE HERBIG BE STAR BD+65 1637

    We attempt to constrain the physical properties of the inner, gaseous disk of the Herbig Be star BD+65 1637 using non-LTE, circumstellar disk codes and observed spectra (3700–10500 Å) from the ESPaDOnS instrument on the Canada–France–Hawaii Telescope. The photoionizing radiation of the central star is assumed to be the sole source of input energy for the disk. We model optical and near-infrared emission lines that are thought to form in this region using standard techniques that have been successful in modeling the spectra of classical Be stars. By comparing synthetic line profiles of hydrogen, helium, iron, and calcium with the observed line profiles, we try to constrain the geometry, density structure, and kinematics of the gaseous disk. Reasonable matches have been found for all line profiles individually; however, no disk density model based on a single power law for the equatorial density was able to simultaneously fit all of the observed emission lines. Among the emission lines, the metal lines, especially the Ca ii IR triplet, seem to require higher disk densities than the other lines. Excluding the Ca ii lines, a model in which the equatorial disk density falls as 10{sup −10} (R{sub *}/R){sup 3} g cm{sup −3} seen at an inclination of 45° for a 50 R{sub *} disk provides reasonable matches to the overall line shapes and strengths. The Ca ii lines seem to require a shallower drop-off as 10{sup −10} (R{sub *}/R){sup 2} g cm{sup −3} to match their strength. More complex disk density models are likely required to refine the match to the BD+65 1637 spectrum.

  20. Role of the superoxide anion in the oxidative activation of the new antitumor drug BD40: a radiolysis study

    International Nuclear Information System (INIS)

    BD40, a new antitumor drug derived from 9-azaellipticine, is thought to have an oxygen-dependent metabolism in vivo. The one-electron oxidation of this drug was effected by γ radiolysis using OH radical free radicals as oxidants and the reaction of O2anionradical with the BD40 oxidized transient(s). The absorption spectrum of the one-electron oxidized free radical was determined by pulse radiolysis using OH radical or N3radical as reactant. In the absence of O2 and O2anionradical, the initial yield of disappearance of the drug is equal to 2.5 x 10-7 molJ-1 independently of the initial concentration of the drug and of the dose rate. When BD40 is oxidized by OH anion radicals in the presence of O2 and O2anionradical, the yield is the same. This yield is halved if superoxide dismutase is present during irradiation. Superoxide anions do not react directly with the drug. Thus it is suggested that these radicals oxidize the BD40 free radical produced by oxidation with OH radical. Biological implications are discussed. (author)

    Nitric oxide (NO) is a toxic free radical produced by neutrophils and macrophages in response to infection. Uropathogenic Escherichia coli (UPEC) induces a variety of defence mechanisms in response to NO, including direct NO detoxification (Hmp, NorVW, NrfA), iron-sulphur cluster repair (YtfE), and the expression of the NO-tolerant cytochrome bd-I respiratory oxidase (CydAB). The current study quantifies the relative contribution of these systems to UPEC growth and survival during infection. Loss of the flavohemoglobin Hmp and cytochrome bd-I elicit the greatest sensitivity to NO-mediated growth inhibition, whereas all but the periplasmic nitrite reductase NrfA provide protection against neutrophil killing and promote survival within activated macrophages. Intriguingly, the cytochrome bd-I respiratory oxidase was the only system that augmented UPEC survival in a mouse model after 2 days, suggesting that maintaining aerobic respiration under conditions of nitrosative stress is a key factor for host colonisation. These findings suggest that while UPEC have acquired a host of specialized mechanisms to evade nitrosative stresses, the cytochrome bd-I respiratory oxidase is the main contributor to NO tolerance and host colonisation under microaerobic conditions. This respiratory complex is therefore of major importance for the accumulation of high bacterial loads during infection of the urinary tract. PMID:27767067

  3. Factors affecting the response of the bubble detector BD-100 and a comparison of its response to CR-39

    International Nuclear Information System (INIS)

    The BD-100 is a bubble detector available commercially from Chalk River Nuclear Laboratories, Canada for neutron dosimetry. According to the manufacturer, the BD-100 detects neutrons over an energy range of 100 keV to 14 MeV and the dose equivalent response is independent of energy. The sensitivity of the detector is dependent upon its temperature at the time of irradiation. The sensitized detector self-nucleates upon sharp impact and when heated to temperatures of 480C or greater. The BD-100 is insensitive to low energy gamma rays but responds to 6 MeV photons. The sensitivity (bubbles/μSv) of the BD-100 was found to be energy dependent when exposed to standard neutron sources with average energies ranging from 0.5 to 4.5 MeV. The bubbles formed upon irradiation continued to grow in size with time. The response of electrochemically etched CR-39 to the same neutron sources is also reported for comparison

    The carbon-enhanced metal-poor star BD+44°493 ([Fe/H] = -3.9) has been proposed as a candidate second-generation star enriched by metals from a single Pop III star. We report the first detections of P and S and the second detection of Zn in any extremely metal-poor carbon-enhanced star, using new spectra of BD+44°493 collected by the Cosmic Origins Spectrograph on the Hubble Space Telescope. We derive [P/Fe] = -0.34 ± 0.21, [S/Fe] = +0.07 ± 0.41, and [Zn/Fe] = -0.10 ± 0.24. We increase by 10-fold the number of Si i lines detected in BD+44°493, yielding [Si/Fe] = +0.15 ± 0.22. The [S/Fe] and [Zn/Fe] ratios exclude the hypothesis that the abundance pattern in BD+44°493 results from depletion of refractory elements onto dust grains. Comparison with zero-metallicity supernova (SN) models suggests that the stellar progenitor that enriched BD+44°493 was massive and ejected much less than 0.07 M ⊙ of 56Ni, characteristic of a faint SN. Based on observations made with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute (STScI), which is operated by the Association of Universities for Research in Astronomy, Inc. (AURA) under NASA contract NAS 5-26555. These observations are associated with program GO-14231.

Under the optimized conditions , the glycan synthesized by L. mesenteroides BD1710 in the tomato juice-sucrose medium could reached 32.15 g/L , at the same level or a little higher than the yield of glycan by the same bacterial strain in a reported chemically defined medium suitable for Leuconostoc mesenteroides to express polysaccharides. The polymers obtained from the fermented tomato juice-sucrose medium by L.mesenteroides BD1710 via alchol participation was composed of 97.54 %carbohydrate and 0.72%protein, respectively. Therefore, tomato juice-sucrose medium could be an alternative of chemically defined medium for L. mesenteroides strains to biosynthesis glycan.

Therefore, tomato juice-sucrose medium could be an alternative of chemically defined medium for L. mesenteroides strains to biosynthesis glycan.%研究了肠膜明串珠菌BD1710(L. mesenteroides BD1710,CGMCC NO.6432)以TSM为基料时,接种量、初始pH、番茄汁浓度、蔗糖浓度、发酵温度对多糖产量的影响,同时,比较了肠膜明串珠菌BD1710在最优条件下发酵TSM和CDM的多糖产量,并对所获得的多糖组成进行了分析。结果表明:肠膜明串珠菌BD1710发酵TSM产多糖的最适条件分别为接种量2.0%(体积分数)、初始pH 7.0、番茄汁浓度100%(体积分数)、蔗糖浓度15%、发酵温度28℃。在优化条件下,肠膜明串珠菌BD1710的多糖产量最高可达32.15 g/L,与在CDM中多糖的产量相当。采用乙醇沉淀的方法从BD1710发酵TSM得到的多糖碳水化合物含量为97.54%,蛋白质含量为0.72%。因此,TSM可替代CDM来应用于明串珠菌合成多糖。

    Paenibacillus bovis sp. nov BD3526 synthesizes a large amount of exopolysaccharides (EPSs) (36.25g/L) in a semi-defined chemical medium containing 20% (w/v) sucrose. The EPSs were extracted from the cultured broth by ethanol precipitation and purified via anion-exchange and gel permeation chromatography. The Fourier transform infrared (FT-IR) and nuclear magnetic resonance (NMR) spectra showed that the primary EPS fraction (F1) was a linear β (2→6)-linked levan. The peak molecular weight (Mp) of the levan exceeded 2.6×10(6)Da based on high-performance size-exclusion chromatography (HPSEC). The levan adopted a spherical conformation in aqueous solution as confirmed by transmission electron microscopy (TEM). The corresponding levansucrase was identified by SDS-PAGE analysis and in situ polymer synthesis. The in vitro assay demonstrated that the levan significantly stimulated the proliferation of spleen cells and induced the expression of TNF-α, indicating its potential as a natural immunomodulator.

    Medium- and very-high-sensitivity neutron bubble dosimeters (BD-PNDs) made by Bubble Technology Industries (BTI) were used to study the life span of such dosimeters in a standard setup with a {sup 252}Cf source. Although data on the longevity of bubble dosimeters with low and medium sensitivity exist, such data for dosimeters with high and very high sensitivity are not readily available. The manufacturer guarantees optimum dosimeter performance for 3 months after receipt. However, it is important to know the change in the dosimeters' characteristics with time, especially after the first 3 months. The long-term performance of four sets of very high sensitivity and one set of medium-sensitivity bubble dosimeters was examined for periods of up to 13 months. During that time, the detectors were exposed and reset more than 20 times. Although departures from initial detection sensitivity were observed in several cases, the detectors indicated a significantly longer life span than stated in the manufacturer's warranty. In addition, the change in the number of bubbles and in evaluated neutron dose as a function of the time from the end of exposure until the dosimeters were read was investigated.

    GNSS (Global Navigation Satellite System) technology not only in the general field of surveying and mapping, geology, mining, water and electricity, and in particular in the field of public security, fire protection, tourism, search and rescue, adventure have been more widely used. These special areas require real-time and high positioning accuracy. Currently, GNSS precision positioning technology has become a hot research direction. This paper introduced an algorithm of smoothing pseudo range by Doppler based GPS/BD to improve GNSS positioning precision. This algorithm decoded the pseudo range data and ephemeris data, and then designed algorithm of smoothing pseudo range by Doppler according principle of Doppler smoothing pseudo range. This algorithm was realized by C++ and proved its efficiency. At last, this algorithm has proved its correctness through calculating and analyzing practical Doppler and pseudo range data, and then a conclusion has been obtained: the Doppler value precision is sub-meter, far better than the pseudo-range accuracy, so that if the two data are combined to calculate position that can help to improve the positioning accuracy.

    2015-01-01

    We attempt to constrain the physical properties of the inner, gaseous disk of the Herbig Be star BD+65 1637 using non-LTE, circumstellar disk codes and observed spectra (3700 to 10,500 \\r{A}) from the ESPaDOnS instrument on CFHT. The photoionizing radiation of the central star is assumed to be the sole source of input energy for the disk. We model optical and near-infrared emission lines that are thought to form in this region using standard techniques that have been successful in modeling the spectra of Classical Be stars. By comparing synthetic line profiles of hydrogen, helium, iron and calcium with the observed line profiles, we try to constrain the geometry, density structure, and kinematics of the gaseous disk. Reasonable matches have been found for all line profiles individually; however, no disk density model based on a single power-law for the equatorial density was able to simultaneously fit all of the observed emission lines. Amongst the emission lines, the metal lines, especially the Ca II IR trip...

    We discussed some main issues of combined GPS/BD single point positioning. A pro- gram was developed to process the combined GPS/BD data. Availability and positioning accuracy of BD and combined GPS/BD were analyzed. Preliminary results show that BD can provide re- gional navigation and positioning service with a accuracy of around 15 meters. Combined GP, S and BD cannot improve positioning accuracy under the condition that enough visible GPS satellites are available. In the case of bad GPS satellites geometry with insufficient visible GPS satellites, com- bined GPS/BD can improve positioning stability and accuracy.%讨论了GPS/BD组合定位需要考虑的主要问题,自编了GPS/BD组合定位程序,利用实测GPS/BD观测数据分析了当前北斗导航定位系统可用性及GPS/BD组合前后的定位精度。试验结果表明,北斗已经能够提供区域的实时导航定位服务。GPS/BD组合定位在GPS观测卫星数较多时对GPS定位精度改善不明显,在GPS观测卫星数较少时可以显著提高定位精度和稳定性。

    Ultraviolet flux variations are reported for the pulsating extreme helium star BD + 13/sup 0/3224 (V652 Her). Effective temperature and angular radius variations over a cycle are determined from static plane-parallel LTE model atmospheres. When compared with radius changes derived from ground-based spectroscopy, the angular radius variations indicate radial pulsations and correspond to a distance of 1.5 +- 0.1 kpc. BD + 13/sup 0/3224 is thought to be a helium-burning star of 0.7 Msolar masses, which has an envelope contracting as the helium-burning core grows; it is similar to HD 144941 and these two stars may constitute a new sub-class of the hydrogen-deficient stars.

    Non-thermal radiation has been predicted within bow shocks around runaway stars by recent theoretical works. We present X-ray observations towards the runaway stars $\\zeta$ Oph (Chandra and Suzaku) and BD+433654 (XMM-Newton) to search for the presence of non-thermal X-ray emission. We found no evidence of non-thermal emission spatially coincident with the bow shocks, nonetheless, diffuse emission is detected in the vicinity of $\\zeta$ Oph. After a careful analysis of its spectral characteristics we conclude that this emission has a thermal nature with a plasma temperature of $T \\approx 2 \\times10^{6}$ K. The cometary shape of this emission seems to be in line with recent predictions of radiation-hydrodynamic models of runaway stars. The case of BD+433654 is puzzling as non-thermal emission has been reported in a previous work for this source.

  17. Inclusive decays of the B meson and possible life-time difference between Bd0 and B± mesons

    International Nuclear Information System (INIS)

    We study branching ratios of the inclusive semileptonic decay and the inclusive anti ccanti s decay of the B meson in the spectator model, focusing on the life-time difference between Bd0 and B+ mesons. In the case of τsub(B±)/τsub(Bd0)=1, it is impossible to get the branching ratio below 12% for B→eνX without going over 20% for B→anti ccanti s, which is unfavored by the inclusive K- decay of the B meson. It is found that the sizable life-time difference leads to the reasonable inclusive semileptonic decay rate and the inclusive anti ccanti s decay rate. (orig.)

    Additional observations of maxima of the pulsating hydrogen-deficient star, BD + 13/sup 0/ 3224 (V652 Her), give an improved ephemeris for the decreasing period of pulsation. A simple quadratic no longer appears sufficient and a cubic solution may be preferable, indicating that the pulsation decrease rate is slowing down as the star contracts. An alternative hypotheses, that the star is a binary is also discussed.

    2013-06-01

    Full Text Available The aim of the present paper is to return to the discussion on the authorship of BdT 392.5 and argue for attributing the poem to Raimbaut de Vaqueiras. I believe that the affinities in theme, situation and expression between “[Oi] altas undas que venez suz la mar” and the song “Belh Monruelh” (BdT 70.11, that I tried to link to Raimbaut in a previous study, should not be overlooked. An important clue is that the wind motif, present in the latter song, also occurs several times in the Occitan troubadour’s production, to the extent that it would seem a tried and tested semiotic marker. Neither should the underlying narrative quality of the text in search of an author be ignored, nor the popular tone that characterizes it, which are both compatible with attitudes expressed by the “fill d’un paubre cavaillier de Proensa”, who frequently makes use of popular song and does not shun the adoption and elevation in a classless manner of features of more ‘humble’ origin. Moreover, of utmost importance is the use in l. 10 of BdT 392.5a of the verb-form “aportai”, an imperative form (confirmed by the rhyme found in northern Italy (and in particular in the Liguria-Piedmont area, where Raimbaut spent many years and which is employed, as a clear dialect feature, significantly in l. 27 of the ‘tenso’ between the Occitan troubadour and the Genoese lady (BdT 392.7.

    We report the detection of Cd I (Z = 48), Lu II (Z = 71), and Os II (Z = 76) in the metal-poor star BD+173248. These abundances are derived from an ultraviolet spectrum obtained with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope. This is the first detection of these neutron-capture species in a metal-poor star enriched by the r-process. We supplement these measurements with new abundances of Mo I, Ru I, and Rh I derived from an optical spectrum obtained with the High Resolution Echelle Spectrograph on Keck. Combined with previous abundance derivations, 32 neutron-capture elements have been detected in BD+173248, the most complete neutron-capture abundance pattern in any metal-poor star to date. The light neutron-capture elements (38 <= Z <= 48) show a more pronounced even-odd effect than expected from current Solar system r-process abundance predictions. The age for BD+173248 derived from the Th II/Os II chronometer is in better agreement with the age derived from other chronome...

    The parallaxes of stars determined from the multichannel astrometric photometer (MAP) in the regions of Lalande 21185, BD 56 deg 2966, and from photographic plates in the region of BD 56 deg 2966 and the region of HR 4783 and HR 4784 are reported. The parallax determined for Lalande 21185, 395.1 +/-1.0 mas yields what is believed to be the most precise distance modulus (-2.984 +/-0.0055) known for a star other than the sun. The absolute magnitude of Lalande 21185 is found to be 10.474 +/-0.008. No significant evidence of unseen companions is detected. The photographic study of BD 56 deg 2966 indicates that the long-term (65 yr) motion of the star is linear to better than +/-16 mas, while the MAP study indicates that the motion is linear to better than +/-2.5 mas over a period of some 5 yr. The photographically determined parallaxes are compared with those observed with the MAP. The photographically calculated standard errors are found to be in agreement with the standard error of the differences.

    Full Text Available Abstract Background Epithelial defensins including human β-defensins (hBDs and α-defensins (HDs are antimicrobial peptides that play important roles in the mucosal defense system. However, the role of defensins in papillomavirus induced epithelial lesions is unknown. Results Papilloma tissues were prospectively collected from 15 patients with recurrent respiratory papillomatosis (RRP and analyzed for defensins and chemokine IL-8 expression by quantitative, reverse-transcriptase polymerase chain reaction (RT-PCR assays. HBD-1, -2 and -3 mRNAs were detectable in papilloma samples from all RRP patients and the levels were higher than in normal oral mucosal tissues from healthy individuals. Immunohistochemical analysis showed that both hBD-1 and 2 were localized in the upper epithelial layers of papilloma tissues. Expression of hBD-2 and hBD-3 appeared to be correlated as indicated by scatter plot analysis (r = 0.837, p Conclusion Human β-defensins are upregulated in respiratory papillomas. This novel finding suggests that hBDs might contribute to innate and adaptive immune responses targeted against papillomavirus-induced epithelial lesions.

    Introduction: Failure of treatment for high grade gliomas is usually due to local recurrence at the site of surgical resec-tion indicating that a more aggressive form of local therapy could be of benefit. Photodynamic therapy (PDT) is a local form of treatment involving the administration of a tumor-localizing photosensitizing drug that is activated by light of a specific wavelength The results of in vitro experiments indicated that PDT, given at low fluence rates was substantially more effective at inhibiting glioma spheroid growth than short term high fluence rate regimes. This prompted the initia-tion of in vivo studies of low fluence rate 5-aminolevulinic acid (ALA) PDT in a rat glioma model. Methods:BT4C cell line tumors were established in the brains of inbred BD- IX rats. Eighteen days following tumor induction the animals were injected with 125 mg/kg ALA ip. and four hours later light treatment at various fluences and fluence rates were given after the introduction of an optical fiber. Tumor histology and animal survival were examined. Results: In vitro experiments verified that the cell line was sensitive to ALA PDT. Microfluorometry of frozen tissue sections showed that PpIX is produced with a greater than 20:1 tumor to normal tissue selectivity ratio four hours after ALA injection. Histological examination demonstrated neutrophil infiltration and tumor central necrosis in low fluence rate treated tumors. Conclusions: Low fluence rate long term ALA mediated PDT had a more pronounced effect on tumor histology than single shot short duration treatments at similar total fluence levels.

    Deregulation is haltingly changing the United States electricity markets. The resulting uncertainty and/or rising energy costs can be hedged by generating electricity on-site and other benefits, such as use of otherwise wasted heat, can be captured. The Public Utility Regulatory Policy Act (PURPA) of 1978 first invited relatively small-scale generators ({ge} 1 MW) into the electricity market. The advent of efficient and reliable small scale and renewable equipment has spurred an industry that has, in recent years, made even smaller (business scale) electricity generation an economically viable option for some consumers. On-site energy capture and/or conversion, known as distributed energy resources (DER), offers consumers many benefits, such as economic savings and price predictability, improved reliability, control over power quality, and emissions reductions. Despite these benefits, DER adoption can be a daunting move to a customer accustomed to simply paying a monthly utility bill. San Diego is in many ways an attractive location for DER development: It has high electricity prices typical of California and a moderate climate i.e. energy loads are consistent throughout the year. Additionally, the price shock to San Diego Gas and Electric (SDG&E) customers during the summer of 2000 has interested many in alternatives to electricity price vulnerability. This report examines the business case for DER at the San Diego biotechnology supply company, BD Biosciences Pharmingen, which considered DER for a building with 200-300 kW base-load, much of which accommodates the refrigerators required to maintain chemicals. Because of the Mediterranean climate of the San Diego area and the high rate of air changes required due to on-site use of chemicals, modest space heating is required throughout the year. Employees work in the building during normal weekday business hours, and daily peak loads are typically about 500 kW.

    Targeting respiration and ATP synthesis has received strong interest as a new strategy for combatting drug-resistant Mycobacterium tuberculosis. Mycobacteria employ a respiratory chain terminating with two branches. One of the branches includes a cytochrome bc1 complex and an aa3-type cytochrome c oxidase while the other branch terminates with a cytochrome bd-type quinol oxidase. In this communication we show that genetic inactivation of cytochrome bd, but not of cytochrome bc1, enhances the susceptibility of Mycobacterium smegmatis to hydrogen peroxide and antibiotic-induced stress. The type-II NADH dehydrogenase effector clofazimine and the ATP synthase inhibitor bedaquiline were bacteriostatic against wild-type M. smegmatis, but strongly bactericidal against a cytochrome bd mutant. We also demonstrated that the quinone-analog aurachin D inhibited mycobacterial cytochrome bd at sub-micromolar concentrations. Our results identify cytochrome bd as a key survival factor in M. smegmatis during antibiotic stress. Targeting the cytochrome bd respiratory branch therefore appears to be a promising strategy that may enhance the bactericidal activity of existing tuberculosis drugs. PMID:26015371

    Gly m Bd 28K is one of the major allergens in soybeans, but there is limited information on its IgG-binding epitopes. Thirty-four overlapping peptides that covered the entire sequence of Gly m Bd 28K were synthesized, and 3 monoclonal antibodies against Gly m Bd 28K were utilized to identify the IgG-binding regions of Gly m Bd 28K. Three dominant peptides corresponding to (28)GDKKSPKSLFLMSNS(42)(G28-S42), (56)LKSHGGRIFYRHMHI(70)(L56-I70), and (154)ETFQSFYIGGGANSH(168)(E154-H168) were recognized. L56-I70 is the most important epitope, and a competitive ELISA indicated that it could inhibit the binding of monoclonal antibody to Gly m Bd 28K protein. Alanine scanning of L56-I70 documented that F64, Y65, and R66 were the critical amino acids of this epitope. Two bioinformatics tools, ABCpred and BepiPred, were used to predict the epitopes of Gly m Bd 28K, and the predictions were compared with the epitopes that we had located by monoclonal antibodies.

    Full Text Available BACKGROUND: Adults with bipolar disorder (BD have cognitive impairments that affect face processing and social cognition. However, it remains unknown whether these deficits in euthymic BD have impaired brain markers of emotional processing. METHODOLOGY/PRINCIPAL FINDINGS: We recruited twenty six participants, 13 controls subjects with an equal number of euthymic BD participants. We used an event-related potential (ERP assessment of a dual valence task (DVT, in which faces (angry and happy, words (pleasant and unpleasant, and face-word simultaneous combinations are presented to test the effects of the stimulus type (face vs word and valence (positive vs. negative. All participants received clinical, neuropsychological and social cognition evaluations. ERP analysis revealed that both groups showed N170 modulation of stimulus type effects (face > word. BD patients exhibited reduced and enhanced N170 to facial and semantic valence, respectively. The neural source estimation of N170 was a posterior section of the fusiform gyrus (FG, including the face fusiform area (FFA. Neural generators of N170 for faces (FG and FFA were reduced in BD. In these patients, N170 modulation was associated with social cognition (theory of mind. CONCLUSIONS/SIGNIFICANCE: This is the first report of euthymic BD exhibiting abnormal N170 emotional discrimination associated with theory of mind impairments.

    2012-02-01

    Full Text Available Abstract Background Pseudofactin II is a recently identified biosurfactant secreted by Pseudomonas fluorescens BD5, the strain obtained from freshwater from the Arctic Archipelago of Svalbard. Pseudofactin II is a novel compound identified as cyclic lipopeptide with a palmitic acid connected to the terminal amino group of eighth amino acid in peptide moiety. The C-terminal carboxylic group of the last amino acid forms a lactone with the hydroxyl of Thr3. Adhesion is the first stage of biofilm formation and the best moment for the action of antiadhesive and anti-biofilm compounds. Adsorption of biosurfactants to a surface e.g. glass, polystyrene, silicone modifies its hydrophobicity, interfering with the microbial adhesion and desorption processes. In this study the role and applications of pseudofactin II as a antiadhesive compound has been investigated from medicinal and therapeutic perspectives. Results Pseudofactin II lowered the adhesion to three types of surfaces (glass, polystyrene and silicone of bacterial strains of five species: Escherichia coli, Enterococcus faecalis, Enterococcus hirae, Staphylococcus epidermidis, Proteus mirabilis and two Candida albicans strains. Pretreatment of a polystyrene surface with 0.5 mg/ml pseudofactin II inhibited bacterial adhesion by 36-90% and that of C. albicans by 92-99%. The same concentration of pseudofactin II dislodged 26-70% of preexisting biofilms grown on previously untreated surfaces. Pseudofactin II also caused a marked inhibition of the initial adhesion of E. faecalis, E. coli, E. hirae and C. albicans strains to silicone urethral catheters. The highest concentration tested (0.5 mg/ml caused a total growth inhibition of S. epidermidis, partial (18-37% inhibition of other bacteria and 8-9% inhibition of C. albicans growth. Conclusion Pseudofactin II showed antiadhesive activity against several pathogenic microorganisms which are potential biofilm formers on catheters, implants and internal

    Chromosome integrity depends on DNA structure-specific processing complexes that resolve DNA entanglement between sister chromatids. If left unresolved, these entanglements can generate either chromatin bridging or ultrafine DNA bridging in the anaphase of mitosis. These bridge structures...... are defined by the presence of the PICH protein, which interacts with the BEND3 protein in mitosis. To obtain structural insights into PICH-BEND3 complex formation at the atomic level, their respective NTPR and BD1 domains were cloned, overexpressed and crystallized using 1.56 M ammonium sulfate...

    2013-01-01

    I review the status of the rare decays B_s --> mu+mu- and B_d --> mu+mu-. The latest Standard Model predictions for the corresponding branching ratios are discussed. An overview of additional observables that are accessible in the B_s --> mu+mu- decay is given. The new physics implications of the recent measurement of the B_s --> mu+mu- branching ratio are discussed both model independently and in the context of the Minimal Supersymmetric Standard Model.

    Cytochrome bd oxidases are membrane proteins expressed by bacteria including a number of pathogens, which make them an attractive target for the discovery of new antibiotics. An electrochemical assay is developed to study the activity of these proteins and inhibition by quinone binding site tool compounds. The setup relies on their immobilization at electrodes specifically modified with gold nanoparticles, which allows achieving a direct electron transfer to/from the heme cofactors of this large enzyme. After optimization of the protein coverages, the assay shows at pH7 a good reproducibility and readout stability over time, and it is thus suitable for further screening of small molecule collections.

    2010-01-01

    The analysis of the penguin decay Bd->K*MuMu at LHCb can act as a laboratory for the discovery and understanding of new physics. Through the Operator Product Expansion, the decay kinematics are well understood in both the Standard Model and in a large range of new physics scenarios. The theoretical errors from QCD effects can be characterized and a set of observables have been derived which minimise their influence in measurements. We will describe how these measurements can be made in LHCb with special emphasis on what can be done with a first run of the LHC with a few hundred pb-1 of integrated luminosity.

  17. Skin Bacteria Diversity and Spatial Distribution in Litoria genimaculata (GREEN- EYED TREE FROG Body Parts and its Bd-Inhibitory Activity -abstract-

    Full Text Available Several amphibian skin bacteria have shown inhibitory activity against the pathogenic fungus Batrachochytrium dendrobatidis (Bd. However‚ little is known about the spatial distribution of these inhibitory bacteria on amphibian skin‚ or their diversity. We looked at the diversity and distribution of skin bacteria of the green-eyed tree frog Litoria genimaculata. This stream-dwelling species from North Queensland rainforest declined in the early 1990s but has since recovered to pre-decline range population sizes. Swabs were taken from 5 body parts (hands‚ feet‚ legs and dorsal and ventral surfaces and inoculated onto agar plates for isolation of bacterial colonies. Bd- inhibitory activity was tested in challenge essays. Results show that feet had the highest number of bacterial isolates with Bd inhibitory activity followed by hands and legs with similar numbers of bacterial isolates and ventral body parts in that order. The dorsal surface had the lowest number of Bd inhibitory isolates. No sampled frogs were infected with Bd according to PCR assays‚ although Bd is endemic at the site. Information from morphological observations and Gram stains will be used to classify the bacterial isolates. Results will be analyzed for any patterns of distribution across the body of the frogs. Possible associations between body parts and bacterial isolates with and without Bd-inhibitory activity will be examined. This study will contribute to knowledge of the community structure of skin bacteria in frogs. Characterization of skin bacteria diversity is one of the first steps in understanding the role of amphibian skin bacteria in the resistance of the hosts to chytridiomycosis.

  18. Improved management of SG BD demineralizer for reduced generation of low-level radioactive spent resin in Korean nuclear power plants

    International Nuclear Information System (INIS)

    Most nuclear power plants in Korea have adopted Ethanolamine(ETA) as a secondary pH control agent to increase the pH at the liquid phase, which may reduce the corrosion in steam generator tubes and moisture separator/reheat system. Along with its beneficial effect of SG protection from corrosion and degradation, the replacement of ammonia with ETA causes the increased generation of spent resin and the reduced run time of demineralizer in steam generator blowdown(SG BD) system. The composition ratio of cation- to anion- exchange resin in SG BD mixed bed should be increased in the ETA chemistry environment to meet the ratio of cation to anion in the aqueous solution, which results in the simultaneous exhaustion of cation and anion exchange resins. The utilization rate of mixed bed is greatest at the cation-to-anion ratio of 95:1 on the theoretical equivalent basis in the solution, but practically highest at that of 22:1 due to the possible inhomogeneous distribution of cation and anion exchange resins in SG BD bed. The run time of the bed could be extended by 30% such that, at that much, the purchase cost of new resin is saved and the production rate of spent resin is reduced. The guideline on the replacement of resin in SG BD bed is not necessary to secure the removal of radioactive particles without the leakage of the primary coolant into the secondary side since all the radioactive ions can be eliminated by SG BD bed with the sufficient time. They are retained during more than one month after their ingress into the SG BD bed without leakage. With the reduced replacement, thus, the SG BD spent resin that comprises 65% of low-level radioactive solid waste can be much cut down

    Using 355 pb^-1 of data collected by the CDF II detector in \\ppbar collisions at sqrt{s} = 1.96 TeV at the Fermilab Tevatron, we study the fully reconstructed hadronic decays B -> D pi and B -> D pi pi pi. We present the first measurement of the ratio of branching fractions B(Bs -> Ds pi pi pi) / B(Bd -> Dd pi pi pi) = 1.05 pm 0.10 (stat) pm 0.22 (syst). We also update our measurement of B(Bs -> Ds pi) / B(Bd -> Dd pi) to 1.13 pm 0.08 (stat) pm 0.23 (syst) improving the statistical uncertainty by more than a factor of two. We find B(Bs -> Ds pi) = [3.8 pm 0.3 (stat) pm 1.3 (syst)] \\times 10^{-3} and B(Bs -> Ds pi pi pi) = [8.4 pm 0.8 (stat) pm 3.2 (syst)] \\times 10^{-3}.

    Context. The fact that eclipsing binaries belong to a stellar group is useful, because the former can be used to estimate distance and additional properties of the latter, and vice versa. Aims. Our goal is to analyse new spectroscopic observations of BD$+36^\\circ3317$ along with the photometric observations from the literature and, for the first time, to derive all basic physical properties of this binary. We aim to find out whether the binary is indeed a member of the $\\delta$ Lyr open cluster. Methods. The spectra were reduced using the IRAF program and the radial velocities were measured with the program SPEFO. The line spectra of both components were disentangled with the program KOREL and compared to a grid of synthetic spectra. The final combined radial-velocity and photometric solution was obtained with the program PHOEBE. Results. We obtained the following physical elements of BD$+36^\\circ3317$: $M_1 = 2.24\\pm0.07 M_{\\odot}$, $M_2 = 1.52\\pm0.03 M_{\\odot}$, $R_1 = 1.76\\pm0.01 R_{\\odot}$, $R_2 = 1.46\\pm...

    The bow shocks of runaway stars with strong stellar winds of over 2000 km s$^{-1}$ can serve as particle acceleration sites. The conversion from stellar wind luminosity into particle acceleration power has an efficiency of the same order of magnitude as those in supernova remnants, based on the radio emission from the bow shock region of runaway star BD+43$^\\circ$3654 \\citep{Benaglia10}.If this object exhibits typical characteristics, then runaway star systems can contribute a non-negligible fraction of Galactic cosmic-ray electrons. To constrain the maximum energy of accelerated particles from measurements of possible non-thermal emissions in the X-ray band, Suzaku observed BD+43$^\\circ$3654 in April 2011 with an exposure of 99 ks. Because the onboard instruments have a stable and low background level, Suzaku detected a possible enhancement over the background of $7.6\\pm 3.4$ cnt arcmin$^{-2}$ at the bow shock region, where the error represents the 3 sigma statistics only. However, the excess is not signific...

    We present an elemental-abundance analysis, in the near-ultraviolet (NUV) spectral range, for the extremely metal-poor star BD+44 493, a 9th magnitude sub-giant with [Fe/H] = -3.8 and enhanced carbon, based on data acquired with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope. This star is the brightest example of a class of objects that, unlike the great majority of carbon-enhanced metal-poor (CEMP) stars, does not exhibit over-abundances of heavy neutron-capture elements (CEMP-no). In this paper, we validate the abundance determinations for a number of species that were previously studied in the optical region, and obtain strong upper limits for beryllium and boron, as well as for neutron-capture elements from zirconium to platinum, many of which are not accessible from ground-based spectra. The boron upper limit we obtain for BD+44 493, logeps(B) < -0.70, the first such measurement for a CEMP star, is the lowest yet found for very and extremely metal-poor stars. In addition, we ob...

    The amphibian chytrid fungus, Batrachochytrium dendrobatidis, Bd, has been implicated in the decimation and extinction of many amphibian populations worldwide, especially at mid and high elevations. Recent studies have demonstrated the presence of the pathogen in the lowlands from Australia and Central America. We extend here its elevational range by demonstrating its presence at the sea level, in the lowland forests of Gorgona Island, off the Pacific coast of Colombia. We conducted two field surveys, separated by four years, and diagnosed Bd by performing polymerase chain reactions on swab samples from the skin of five amphibian species. All species, including the Critically Endangered Atelopus elegans, tested positive for the pathogen, with prevalences between 3.9 % in A. elegans (in 2010) and 52 % in Pristimantis achatinus. Clinical signs of chytridiomycosis were not detected in any species. To our knowledge, this is the first report of B. dendrobatidis in tropical lowlands at sea level, where temperatures may exceed optimal growth temperatures of this pathogen. This finding highlights the need to understand the mechanisms allowing the interaction between frogs and pathogen in lowland ecosystems. PMID:22669408

    Pseudoxanthomonas spadix BD-a59, isolated from gasoline-contaminated soil, has the ability to degrade all six BTEX (benzene, toluene, ethylbenzene, and o-, m-, and p-xylene) compounds. The genomic features of strain BD-a59 were analyzed bioinformatically and compared with those of another fully sequenced Pseudoxanthomonas strain, P. suwonensis 11-1, which was isolated from cotton waste compost. The genome of strain BD-a59 differed from that of strain 11-1 in many characteristics, including the number of rRNA operons, dioxygenases, monooxygenases, genomic islands (GIs), and heavy metal resistance genes. A high abundance of phage integrases and GIs and the patterns in several other genetic measures (e.g., GC content, GC skew, Karlin signature, and clustered regularly interspaced short palindromic repeat [CRISPR] gene homology) indicated that strain BD-a59's genomic architecture may have been altered through horizontal gene transfers (HGT), phage attack, and genetic reshuffling during its evolutionary history. The genes for benzene/toluene, ethylbenzene, and xylene degradations were encoded on GI-9, -13, and -21, respectively, which suggests that they may have been acquired by HGT. We used bioinformatics to predict the biodegradation pathways of the six BTEX compounds, and these pathways were proved experimentally through the analysis of the intermediates of each BTEX compound using a gas chromatograph and mass spectrometry (GC-MS). The elevated abundances of dioxygenases, monooxygenases, and rRNA operons in strain BD-a59 (relative to strain 11-1), as well as other genomic characteristics, likely confer traits that enhance ecological fitness by enabling strain BD-a59 to degrade hydrocarbons in the soil environment.

    Smokers and individuals exposed to second-hand cigarette smoke have a higher risk of developing chronic sinus and bronchial infections. This suggests that cigarette smoke (CS) has adverse effects on immune defenses against pathogens. Epithelial cells are important in airway innate immunity and are the first line of defense against infection. Airway epithelial cells not only form a physical barrier but also respond to the presence of microbes by secreting antimicrobials, cytokines, and chemokines. These molecules can lyse infectious microorganisms and/or provide signals critical to the initiation of adaptive immune responses. We examined the effects of CS on antimicrobial secretions of primary human nasal epithelial cells (PHNECs). Compared to non-CS-exposed individuals, PHNEC from in vivo CS-exposed individuals secreted less chemokine ligand (C-C motif) 20 (CCL20), Beta-defensin 1 (BD-1), and SLPI apically, less BD-1 and SLPI basolaterally, and more CCL20 basolaterally. Cigarette smoke extract (CSE) exposure in vitro decreased the apical secretion of CCL20 and beta-defensin 1 by PHNEC from non-CS-exposed individuals. Exposing PHNEC from non-CS exposed to CSE also significantly decreased the levels of many mRNA transcripts that are involved in immune signaling. Our results show that in vivo or in vitro exposure to CS alters the secretion of key antimicrobial peptides from PHNEC, but that in vivo CS exposure is a much more important modifier of antimicrobial peptide secretion. Based on the gene expression data, it appears that CSE disrupts multiple immune signaling pathways in PHNEC. Our results provide mechanistic insight into how CS exposure alters the innate immune response and increases an individual’s susceptibility to pathogen infection. PMID:26793127

    Objective: To study the lipopolysaacharide(LPS) neutralization activity and high-salt sensitivity of rh-BD3-BPI, a recombinant human β-defensin 3(hBD3) and bactericidal permeability-increasing protein(BPI) fusion protein. Methods: Standard curve of LPS activity was created using Limulus Amebocyte Lasate test based on stan-dard LPS product. 100 μL serially diluted rhBD3-BPI was mixed with 100 μL 10 EU/mL LPS and incubated in water for 60 minutes at 37℃. 10 EU/mL LPS served as control and water served as blank control. 6×108 CFU/mL standard or clinically isolated wild Gram-positive or -negative bacterial strains were incubated at 37℃ for 3 h in 1 mg/mL rhBD3-BPI supplemented with 0~250 mmol/L of NaCl and then diluted at ratios from 1∶1 to 1∶1000 with 10 mmol/L sodium phosphate. 50 μL cells were plated in LB agar gel and incubated overnight, numbers of bacterial colonies were counted and bactericide rate was calculated. Results: In 5 EU/mL LPS system, LPS activi-ty neutralization was detected when rhBD3-BPI was above 4 μg/mL, 23% and 88% LPS neutralization rates were reached when rhBD3-BPI was 16 and 32 μg/mL, respectively. 50 μg/mL rhBD3-BPI had a 100% bactericidal ef-fect on all the strains. This effect was not influenced by increasing NaCl concentration before reaching 150 mmol/L. When the concentration of NaCl reached 200 mmol/L, the bactericidal effect remained above 90%. Significant decrease only appeared when the concentration of NaCl was above 200 mmol/L, however, the bactericidal effect of rhBD3- BPI remained above 85% even at the NaCl concentration of 250 mmol/L. Conclusion: rhBD3-BPI can neutralize LPS and has a stable bactericidal activity in high-salt solutions.%目的:验证重组人BD3-BPI(rhBD3-BPI)是否具有内毒素中和活性,研究其在高盐环境中是否能保持抗菌活性。方法:根据内毒素标准品绘制内毒素活性标准曲线,将100μL梯度稀释的rhBD3-BPI与100μL 10 EU

    To select a method for detecting methicillin-resistant Staphylococcus aureus (MRSA) in nasal swabs, we compared BD GeneOhm MRSA PCR and various culture media (mannitol salt agar with cefoxitin, MRSASelect, CHROMagar MRSA, and Spectra MRSA). While PCR detection of MRSA was more rapid, MRSASelect and Spectra MRSA demonstrated performance equivalent to that of PCR with maximal detection at 24 h.

  11. TRUMP-BD: A computer code for the analysis of nuclear fuel assemblies under severe accident conditions

    International Nuclear Information System (INIS)

    TRUMP-BD (Boil Down) is an extension of the TRUMP (Edwards 1972) computer program for the analysis of nuclear fuel assemblies under severe accident conditions. This extension allows prediction of the heat transfer rates, metal-water oxidation rates, fission product release rates, steam generation and consumption rates, and temperature distributions for nuclear fuel assemblies under core uncovery conditions. The heat transfer processes include conduction in solid structures, convection across fluid-solid boundaries, and radiation between interacting surfaces. Metal-water reaction kinetics are modeled with empirical relationships to predict the oxidation rates of steam-exposed Zircaloy and uranium metal. The metal-water oxidation models are parabolic in form with an Arrhenius temperature dependence. Uranium oxidation begins when fuel cladding failure occurs; Zircaloy oxidation occurs continuously at temperatures above 13000 degree F when metal and steam are available. From the metal-water reactions, the hydrogen generation rate, total hydrogen release, and temporal and spatial distribution of oxide formations are computed. Consumption of steam from the oxidation reactions and the effect of hydrogen on the coolant properties is modeled for independent coolant flow channels. Fission product release from exposed uranium metal Zircaloy-clad fuel is modeled using empirical time and temperature relationships that consider the release to be subject to oxidation and volitization/diffusion (''bake-out'') release mechanisms. Release of the volatile species of iodine (I), tellurium (Te), cesium (Ce), ruthenium (Ru), strontium (Sr), zirconium (Zr), cerium (Cr), and barium (Ba) from uranium metal fuel may be modeled

    Chromosome integrity depends on DNA structure-specific processing complexes that resolve DNA entanglement between sister chromatids. If left unresolved, these entanglements can generate either chromatin bridging or ultrafine DNA bridging in the anaphase of mitosis. These bridge structures are defined by the presence of the PICH protein, which interacts with the BEND3 protein in mitosis. To obtain structural insights into PICH-BEND3 complex formation at the atomic level, their respective NTPR and BD1 domains were cloned, overexpressed and crystallized using 1.56 M ammonium sulfate as a precipitant at pH 7.0. The protein complex readily formed large hexagonal crystals belonging to space group P6122, with unit-cell parameters a = b = 47.28, c = 431.58 Å and with one heterodimer in the asymmetric unit. A complete multiwavelength anomalous dispersion (MAD) data set extending to 2.2 Å resolution was collected from a selenomethionine-labelled crystal at the Swiss Light Source. PMID:27487930

    We present new photometric observations in the BVRI bands of the double-lined eclipsing binary BD+05 706 conducted over three observing seasons, as well as new X-ray observations obtained with the ROSAT satellite covering a full orbital cycle (P = 18.9 days). A detailed light-curve analysis of the optical data shows the system to be semidetached, confirming indications from an earlier analysis by Torres et al. (1998), with the less massive and cooler star filling its Roche lobe. The system is a member of the rare class of cool Algol systems, which are different from the "classical" Algol systems in that the mass-gaining component is also a late-type star rather than a B- or A-type star. By combining the new photometry with a reanalysis of the spectroscopic observations reported by Torres et al. (1998) we derive accurate absolute masses for the components of M1 = 2.633 +/- 0.028 Msun and M2 = 0.5412 +/- 0.0093 Msun, radii of R1 = 7.55 +/- 0.20 Rsun and R2 = 11.02 +/- 0.21 Rsun, as well as effective temperature...

    Full Text Available ε-N-Acetylation of lysine residues (Kac is one of the most frequently occurring posttranslational modifications (PTMs which control gene transcription and a vast array of diverse cellular functions. Bromodomains are epigenetic regulators involved in posttranslational modification. In silico docking studies were carried out to evaluate the binding potential of selected rare flavonoids on to Nac binding site of BD1 domain of BRD4 BET family proteins. Rare flavonoids like 3-O-acetylpinobanksin, naringenin triacetate, and kaempferol tetraacetate were found to occupy the WPF shelf and at the same time they exhibited a better binding affinity with multiple crystal structures of first bromodomain BRD4 (BRD4 BD1 when compared with the known inhibitors.

    We report on the results of the first XMM-Newton satellite observation of the luminous and helium-rich O-type subdwarf BD +37{\\deg} 1977 carried out in April 2014. X-ray emission is detected with a flux of about 4*10^(-14) erg/cm2/s (0.2-1.5 keV), corresponding to a f_X/f_bol ratio about 10^(-7); the source spectrum is very soft, and is well fit by the sum of two plasma components at different temperatures. Both characteristics are in agreement with what is observed in the main-sequence early-type stars, where the observed X-ray emission is due to turbulence and shocks in the stellar wind. A smaller but still significant stellar wind has been observed also in BD +37{\\deg} 1977; therefore, we suggest that also in this case the detected X-ray flux has the same origin.

  16. Natural genetic transformation in Acinetobacter sp. BD413 Biofilms: introducing natural genetic transformation as a tool for bioenhancement of biofilm reactors

    2002-07-01

    This study focussed on the localization and quantification of natural genetic transformation using neutral and disadvantageous genes in monoculture biofilms to investigate gene transfer and expression of the transferred genes in the absence of a selective advantage. Data obtained by this investigation were regarded as initial steps for evaluating the applicability of adding catabolic traits into the indigenous bacterial community of biofilm reactors by in situ natural genetic transformation. Because Acinetobacter spp. strains are readily found in waste water treatment plants and because Acinetobacter sp. BD413 possesses a high effective level of competence, natural genetic transformation was investigated in monoculture Acinetobacter sp. BD413 biofilms. The genes used for transformation encoded for the green fluorescent protein (GFP) and its variants. Monitoring of transformation events were performed with the use of automated confocal laser scanning microscopy (CLSM) and semi automated digital image processing and analysis. (orig.)

    To determine wheter bilirubin/extrahepatic bile duct diameter ratio(B/D ratio) or alkalinephosphatase/extrahepatic bile duct diameter ratio (A/D ratio) can be used to differentiate malignant from benigndisease in distal extrahepatic bile duct obstruction during ultrasonographic examination. We retrospectively reviewed the sonograms and laboratory data of 100 patients with obstructive jaundice (benign : n=50, malignant: : n=50). The diagnosis was confirmed either surgically (n=66) or clinically (n=34). The B/D ratio and A/D radio were calculated by means of dividing total bilirubin (mg/dl) and alkaline phosphatase (I.U.)respectively by maximum extrahepatic bile duct diameter(mm) on ultrasonogram. Significant difference in B/D ratio was found between the benignancy (0.28+0.25) and malignancy (0.98+0.84) groups (P<0.001). Significant difference in A/D ratio was also found between the benignancy (15.00+10.22) and malignancy (32.44+30.28) groups(P<0.001) Accuracies to predict malignancy according to criteria of B/D and A/D ratios were less than 75% and 65%respectively. On the other hand, the positive predictive value and specificity were relatively high. The B/D ratio and A/D ratio calculated from ultrasonograms can be used as a valuable screening index todifferentiate malignancy from benignacy in patients with distal extrahepatic bile duct obstruction, especially when the sonography is difficult because of the interposition of bowel gas or obesity

    Gamma-hydroxybutyric acid (GHB) and its "pro-drugs", gamma-butyrolactone (GBL) and 1,4 butanediol (1,4-BD), are drugs of abuse with depressant effects on the central nervous system. Many analytical methods have been proposed for the quantitative determination of these compounds mainly in biological matrices but only few have been addressed to dietary supplements and foods. Facile synthesis of the GBL and 1,4-BD isotopologues are available by "one pot" Ru-catalyzed homogeneous deuteration of dicarboxylic acids. In this work we propose a new method for determination of GHB, GBL and 1,4-BD in commercially available dietary supplements, based on isotope dilution mass spectrometry (ID-MS). The procedure involves a simple extraction of sample with acidic acetonitrile and direct analysis by GC-ID-MS method without any purification or derivatization. Indeed, the proposed method takes advantage of the complete conversion of GHB (free acid or its salts) to GBL, allowing the quantification of GHB and its pro-drugs. Five levels for each calibration curve have been prepared by diluting working solutions of the analytes to obtain concentrations ranging from 1 to 20mg/mL. The validation procedures have shown an accuracy between 88% and 99% and a precision between 7.3% and 2.9% of each analyte in the sample matrix. Positive ions chemical ionization (PICI) have been employed to preserve the information on molecular ions and to improve specificity and sensitivity of quantitative determination.

  3. Potentialities of the LHCb experiment for the discovery of the physics beyond the standard model in the Bd0 → φKS0 decay

    International Nuclear Information System (INIS)

    The Standard Model predicts the same time-dependant CP asymmetry in both Bd0 -> J/ψKS0 and Bd0 → φKS0 decays. This asymmetry is proportional to sin(2*β). Any difference between the CP asymmetries measured in these 2 channels would indicate the presence of new phenomena beyond the Standard Model. We study the sensitivity of the LHCb experiment to this effect. To that end, we estimate the statistical error on the measurement of sin(2*β) in the Bd0 → φKS0 channel by LHCb. We do that with the LHCb classic detector, and then with the re-optimized detector. The number of simulated background events is too small with respect to the annual statistics to obtain precise evaluations. We developed several methods to improve these evaluations. In the most optimistic case, we predict that sin(2*β) would be measured in the LHCb classic configuration with a statistical error equal to 0.56. With the re-optimized detector, this error is further improved: 0.29. (author)

    Highlights: Black-Right-Pointing-Pointer We used a new way of electrical characterization with the charge-to-breakdown test. Black-Right-Pointing-Pointer Measurements are performed directly at probe-die-wafer level. Black-Right-Pointing-Pointer An accurate monitor has been developed to evaluate dice quality and reliability. Black-Right-Pointing-Pointer The extrinsic failures responsible for potential rejects can be identified. Black-Right-Pointing-Pointer Process and gate stress impact can be evaluated with the diversion of Q{sub BD} test. - Abstract: The quality of the gate oxide is a central parameter for power MOSFET devices dedicated to automotive applications. Reliability is systematically evaluated through electrical tests. The purpose of this study is to apply the Q{sub BD} test directly at probe-die-wafer level and to correlate its results with reliability test conclusions. In other words, this new kind of Q{sub BD} test is a monitor of power MOSFET robustness which helps identify extrinsic failures and the process steps responsible. In summary, it is an accurate and fast measurement method of identifying weakened parts and enhancing device quality.

  5. THIRD COMPONENT SEARCH AND ABUNDANCES OF THE VERY DUSTY SHORT-PERIOD BINARY BD +20°307

    International Nuclear Information System (INIS)

    We have obtained near-infrared adaptive optics imaging and collected additional radial velocity observations to search for a third component in the extremely dusty short-period binary system BD +20°307. Our image shows no evidence for a third component at separations greater than 19 AU. Our four seasons of radial velocities have a constant center-of-mass velocity and are consistent with the systemic velocities determined at two earlier epochs. Thus, the radial velocities also provide no support for a third component. Unfortunately, the separation domains covered by our imaging and radial velocity results do not overlap. Thus, we examined the parameters for possible orbits of a third component that could have been missed by our current observations. With our velocities we determined improved circular orbital elements for the 3.4 day double-lined binary. We also performed a spectroscopic abundance analysis of the short-period binary components and conclude that the stars are a mid- and a late-F dwarf. We find that the iron abundances of both components, [Fe/H] = 0.15, are somewhat greater than the solar value and comparable to that of stars in the Hyades. Despite the similarity of the binary components, the lithium abundances of the two stars are very unequal. The primary has log ε (Li) = 2.72, while in the secondary log ε (Li) ≤1.46, which corresponds to a difference of at least a factor of 18. The very disparate lithium abundances in very similar stars make it impossible to ascribe a single age to them. While the system is likely at least 1 Gyr old, it may well be as old as the Sun.

    Context. The fact that eclipsing binaries belong to a stellar group is useful, because the former can be used to estimate distance and additional properties of the latter, and vice versa. Aims: Our goal is to analyse new spectroscopic observations of BD+ 36°3317 along with the photometric observations from the literature and, for the first time, to derive all basic physical properties of this binary. We aim to find out whether the binary is indeed a member of the δ Lyr open cluster. Methods: The spectra were reduced using the IRAF program and the radial velocities were measured with the program SPEFO. The line spectra of both components were disentangled with the program KOREL and compared to a grid of synthetic spectra. The final combined radial-velocity and photometric solution was obtained with the program PHOEBE. Results: We obtained the following physical elements of BD+36°3317: M1 = 2.24 ± 0.07 M⊙, M2 = 1.52 ± 0.03 M⊙, R1 = 1.76 ± 0.01 R⊙, R2 = 1.46 ± 0.01 R⊙, log L1 = 1.52 ± 0.08 L⊙, log L2 = 0.81 ± 0.07 L⊙. We derived the effective temperatures Teff,1 = 10 450 ± 420 K, Teff,2 = 7623 ± 328 K. Both components are located close to zero age main sequence in the Hertzsprung-Russell (HR) diagram and their masses and radii are consistent with the predictions of stellar evolutionary models. Our results imply the average distance to the system d̅ = 330 ± 29 pc. We re-investigated the membership of BD+ 36°3317 in the δ Lyr cluster and confirmed it. The distance to BD+ 36°3317, given above, therefore represents an accurate estimate of the true distance for δ Lyr cluster. Conclusions: The reality of the δ Lyr cluster and the cluster membership of BD+ 36°3317 have been reinforced.

    Gamma-hydroxybutyrate (GHB), and its precursors 1,4-butanediol (1,4-BD) and gamma-butyrolactone (GBL) are known drugs of abuse. The ability of acute and chronic administration of equimolar doses of GHB (200mg/kg), 1,4-BD (174mg/kg) and GBL (166mg/kg) to produce catalepsy in male Swiss Webster mice was examined. GHB, 1,4-BD, GBL produced catalepsy when injected acutely. Drug treatment was then continued for 14days. Tolerance development was determined on days 6, 14, and challenged with a higher dose on day 15 in those chronically pretreated mice, and compared with naïve mice. Chronic GHB produced tolerance to catalepsy, as evidenced from area under the curve (AUC) of catalepsy versus time (min-sec) on days 6 (678±254), 14 (272±247), which were less than those on day 1 (1923±269). However, less tolerance was seen from GBL or 1,4-BD, as AUCs on days 6 and 14 were not significantly lower than that of day 1. In conclusion, although equimolar doses were used, expecting similar levels of GHB in the body, 1,4-BD and GBL shared only some of the in vivo effects of GHB. The rate of metabolic conversion of 1,4-BD and GBL into GHB might be responsible for the differences in the tolerance development to these drugs.

    Full Text Available Abstract Background Increasing reports of carbapenem resistant Acinetobacter baumannii infections are of serious concern. Reliable susceptibility testing results remains a critical issue for the clinical outcome. Automated systems are increasingly used for species identification and susceptibility testing. This study was organized to evaluate the accuracies of three widely used automated susceptibility testing methods for testing the imipenem susceptibilities of A. baumannii isolates, by comparing to the validated test methods. Methods Selected 112 clinical isolates of A. baumanii collected between January 2003 and May 2006 were tested to confirm imipenem susceptibility results. Strains were tested against imipenem by the reference broth microdilution (BMD, disk diffusion (DD, Etest, BD Phoenix, MicroScan WalkAway and Vitek 2 automated systems. Data were analysed by comparing the results from each test method to those produced by the reference BMD test. Results MicroScan performed true identification of all A. baumannii strains while Vitek 2 unidentified one strain, Phoenix unidentified two strains and misidentified two strains. Eighty seven of the strains (78% were resistant to imipenem by BMD. Etest, Vitek 2 and BD Phoenix produced acceptable error rates when tested against imipenem. Etest showed the best performance with only two minor errors (1.8%. Vitek 2 produced eight minor errors(7.2%. BD Phoenix produced three major errors (2.8%. DD produced two very major errors (1.8% (slightly higher (0.3% than the acceptable limit and three major errors (2.7%. MicroScan showed the worst performance in susceptibility testing with unacceptable error rates; 28 very major (25% and 50 minor errors (44.6%. Conclusion Reporting errors for A. baumannii against imipenem do exist in susceptibility testing systems. We suggest clinical laboratories using MicroScan system for routine use should consider using a second, independent antimicrobial susceptibility

DNA retained the ability to be extracted and PCR amplified for more than 2.5 years in both medium types. Prior inability to detect DNA in archived specimens may have been due to failure of the extraction method to isolate DNA from fixed cells.

    We report on a search for Bs->mu+mu- and Bd->mu+mu- decays in ppbar collisions at $\\sqrt{s}$=1.96 TeV using 171 pb-1 of data collected by the CDF II experiment at the Fermilab Tevatron Collider. The decay rates of these rare processes are sensitive to contributions from physics beyond the Standard Model. One event survives all our selection requirements,consistent with the background expectation. We derive branching ratio limits of BR(Bs->mu+mu-) mu+mu-) < 1.5 x 10^-7 at 90% confidence level.

  15. Measurement of B(D0 → K-π+) Using Partial Reconstruction of B → D*+Xscr(l)-bar ν

    International Nuclear Information System (INIS)

    We present a measurement of the absolute branching fraction for D0→K-π+ using the reconstruction of the decay chain B→D*+X ell -ν , D*+→D0π+ where only the lepton and the low-momentum pion from the D*+ are detected. With data collected by the CLEO II detector at the Cornell Electron Storage Ring, we have determined B(D0→K-π+)=[3.81±0.15(stat) ±0.16(syst)]% . copyright 1998 The American Physical Society

    Occurrence of feruloyl-CoA synthetase (fcs) and enoyl-CoA hydratase (ech) genes responsible for the bioconversion of ferulic acid to vanillin have been reported and characterized from Amycolatopsis sp., Streptomyces sp., and Pseudomonas sp. Attempts have been made to express these genes in Escherichia coli DH5α, E. coli JM109, and Pseudomonas fluorescens. However, none of the lactic acid bacteria strain having GRAS status was previously proposed for heterologous expression of fcs and ech genes for production of vanillin through biotechnological process. Present study reports heterologous expression of vanillin synthetic gene cassette bearing fcs and ech genes in a dairy isolate Pediococcus acidilactici BD16. After metabolic engineering, statistical optimization of process parameters that influence ferulic acid to vanillin biotransformation in the recombinant strain was carried out using central composite design of response surface methodology. After scale-up of the process, 3.14 mM vanillin was recovered from 1.08 mM ferulic acid per milligram of recombinant cell biomass within 20 min of biotransformation. From LCMS-ESI spectral analysis, a metabolic pathway of phenolic biotransformations was predicted in the recombinant P. acidilactici BD16 (fcs (+)/ech (+)). PMID:25077778

    The present study aimed to investigate the effects of cytochalasin B (20 μM) on the uptake of 3-O-[(14)C]-methyl-D-glucose or D-[U-(14)C]glucose (8.3 mM each) by BRIN-BD11 cells. Taking into account the distribution space of tritiated water ((3)HOH), which was unexpectedly increased shortly after exposure of the cells to cytochalasin B and then progressively returned to its control values, and that of L-[1-(14)C]glucose, used as an extracellular marker, it was demonstrated that cytochalasin B caused a modest, but significant inhibition of the uptake of D-glucose and its non-metabolized analog by the BRIN-BD11 cells. These findings resemble those observed in acinar or ductal cells of the rat submaxillary gland and displayed a relative magnitude comparable to that found for the inhibition of D-glucose metabolism by cytochalasin B in purified pancreatic islet B cells. These findings reinforce the view that the primary site of action of cytochalasin B is located at the level of the plasma membrane.

    This study describes a validation of the BD Onclarity HPV (Onclarity) assay using the international guidelines for HPV test requirements for cervical cancer screening of women 30 years old and older using Danish SurePath screening samples. The clinical specificity (0.90, 95% confidence interval [CI] = 0.88 to 0.91) and sensitivity (0.97, 95% CI = 0.87 to 1.0) of the Onclarity assay were shown to be not inferior to the reference assay (specificity, 0.90 [95% CI = 0.88 to 0.92]; sensitivity, 0.98 [95% CI = 0.91 to 1.0]). The intralaboratory reproducibility of Onclarity was 97%, with a lower confidence bound of 96% (kappa value, 0.93). The interlaboratory agreement was 97%, with a lower confidence bound of 95% (kappa value, 0.92). The BD Onclarity HPV assay fulfills all the international guidelines for a new HPV test to be used in primarily screening. This is the first clinical validation of a new HPV assay using SurePath screening samples, and thus the Onclarity HPV assay is the first HPV assay to hold an international validation for both SurePath and ThinPrep.

    The performance characteristics of two commercially available rapid tests for influenza, the BD Veritor System for Flu A+B (BD) and the Alere BinaxNOW influenza A&B card (BN), were evaluated using 200 frozen clinical specimens collected from January 2011 to June 2012 from pediatric patients. Real-time reverse transcriptase PCR (RT-PCR) was used as the gold standard to evaluate the results obtained by the two different assays. Of the 200 specimens tested, real-time RT-PCR assay detected influenza A or B virus in 116 samples, while BD detected 104 samples and BN detected 84 samples as positive. The overall sensitivity and specificity for detection of both influenza A and B virus in comparison to those of real-time RT-PCR were 89.6% (95% confidence interval [CI], 82.2 to 94.3) and 98.8% (95% CI, 92.6 to 99.9) for BD Veritor and 72.4% (95% CI, 63.2 to 80.0) and 100% (95% CI, 94.5 to 100.0) for BinaxNOW. Workflow analysis indicated that overall processing times for a batch size of 10 specimens were virtually identical between both systems. Overall, these results indicate that the BD Veritor assay was more sensitive than the BinaxNOW assay in detection of influenza A and B viruses in respiratory specimens from pediatric patients.

    Antimicrobial peptides are multifunctional effector molecules of innate immunity. In this study we investigated whether endothelial cells actively contribute to innate defense mechanisms by expression of antimicrobial peptides. We therefore stimulated human umbilical vein endothelial cells (HUVEC) with inflammatory cytokines, Th17 cytokines, heat-inactivated bacteria, bacterial conditioned medium (BCM) of Staphylococcus aureus and Streptococcus sanguinis, and lipoteichoic acid (LTA). Stimulation with single cytokines induced discrete expression of human β-defensin 3 (hBD3) by IFN-γ or IL-1β and of ribonuclease 7 (RNase7) by TNF-α without any effects on LL-37 gene expression. Stronger hBD3 and RNase7 induction was observed after combined stimulation with IL-1β, TNF-α and IFN-γ and was confirmed by high hBD3 and RNase7 peptide levels in cell culture supernatants. In contrast, Th17 cytokines or stimulation with LTA did not result in AMP production. Moreover, only BCM of an invasive S. aureus bacteremia isolate induced hBD3 in HUVEC. We conclude that endothelial cells actively contribute to prevent dissemination of pathogens at the blood-tissue-barrier by production of AMPs that exhibit microbicidal and immunomodulatory functions. Further investigations should focus on tissue-specific AMP induction in different endothelial cell types, on pathogen-specific induction patterns and potentially involved pattern-recognition receptors of endothelial cells.

    The performance of the BD Phoenix Automated Microbiology System (BD Diagnostic Systems, Sparks, MD) was assessed for identification (ID) and antimicrobial susceptibility testing (AST) of the majority of clinically encountered bacterial isolates in a European collaborative two-center trial. A total of 494 bacterial isolates including various species of the Enterobacteriaceae and 110 nonfermentative gram-negative bacteria were investigated: of these, 385 were single patient isolates, and 109 were challenge strains tested at one center. The performance of the Phoenix extended-spectrum β-lactamase (ESBL) test was also evaluated for 203 strains of Escherichia coli, Klebsiella pneumoniae, and Klebsiella oxytoca included in the study. Forty-two antimicrobial drugs were tested, including members of the following drug classes: aminoglycosides, β-lactam antibiotics, β-lactam/β-lactamase inhibitors, carbapenems, cephems, monobactams, folate antagonists, quinolones, and others. Phoenix system ID results were compared to those of the laboratories' routine ID systems (API 20E and API CHE, ATB ID32E, ID32GN, and VITEK 2 [bioMérieux, Marcy l'Etoile, France]); Phoenix AST results were compared to those of frozen standard broth microdilution (SBM) panels according to NCCLS (now CLSI) guidelines (NCCLS document M100-S9, approved standard M7-A4). Discrepant results were repeated in duplicate. Concordant IDs of 98.4 and 99.1% were observed for the Enterobacteriaceae and the nonfermentative group, respectively. For AST results, the overall essential agreement was 94.2%; the category agreement was 97.3%; and the very major error rate, major error rate, and minor error rate were 1.6, 0.6, and 1.9%, respectively. In terms of ESBL detection, Phoenix results were 98.5% concordant with those of the reference system, with 98.0% sensitivity and 98.7% specificity. In conclusion, the Phoenix ID results showed high agreement with results of the systems to which they were being compared: the

    Context. Evolved stars are crucial pieces for our understanding of the dependency of the planet formation mechanism on the stellar mass and for exploring the mechanism involved in star-planet interactions more deeply. Over the last ten years, we have monitored about 1000 evolved stars for radial velocity variations in the search for low-mass companions under the Penn State - Torun Centre for Astronomy Planet Search program with the Hobby-Eberly Telescope (HET). Selected prospective candidates that required higher RV precision measurements were followed with HARPS-N at the 3.6 m Telescopio Nazionale Galileo under the TAPAS project. Aims: We aim to detect planetary systems around evolved stars to be able to build sound statistics on the frequency and intrinsic nature of these systems, and to deliver in-depth studies of selected planetary systems with evidence of star-planet interaction processes. Methods: For HD 5583 we obtained 14 epochs of precise RV measurements that were collected over 2313 days with the HET, and 22 epochs of ultra-precise HARPS-N data collected over 976 days. For BD+15 2375 we collected 24 epochs of HET data over 3286 days and 25 epochs of HARPS-S data over 902 days. Results: We report the discovery of two planetary mass objects that are orbiting two evolved red giant stars: HD 5583 has a msini = 5.78MJ companion at 0.529 AU in a nearly circular orbit (e = 0.076), the closest companion to a giant star detected with the RV technique, and BD+15 2735 that, with a msini = 1.06MJ, holds the record for the lightest planet orbiting an evolved star found so far (in a circular e = 0.001, 0.576 AU orbit). These are the third and fourth planets found within the TAPAS project, a HARPS-N monitoring of evolved planetary systems identified with the HET. Based on observations obtained with the Hobby-Eberly Telescope, which is a joint project of the University of Texas at Austin, the Pennsylvania State University, Stanford University, Ludwig

    We report on a search for \\bsmm\\ and \\bdmm\\ decays using proton-antiproton collision data at $\\sqrt{s}=1.96$~TeV corresponding to $10~\\fb$ of integrated luminosity collected by the CDF detector at the Fermilab Tevatron collider. The observed number of \\bd\\ candidates is consistent with background-only expectations and yields an upper limit on the branching fraction of $\\brbdmm < 4.6\\times 10^{-9}$ at 95\\% confidence level. We observe an excess of \\bs\\ candidates. The probability that the background processes alone could produce such an excess or larger is $0.94\\%$. The probability that the combination of background and the expected standard model rate of \\bsmm\\ could produce such an excess or larger is $6.8\\%$. These data are used to determine a branching fraction $\\brbsmm = (1.3^{+0.9}_{-0.7}) \\times 10^{-8} $ and provide an upper limit of $\\brbsmm < 3.1\\times 10^{-8}$ at 95\\% confidence level.

  11. SU(3) and CP violating weak and strong final state phases for B_{d}^{0} and B_{s}^{0} decays

    Using rotation in SU(3) space, a set of relations between various decay modes of B_{d}^{0} and B_{s}^{0} are derived. In particular the decays bar{B}_{d}^{0}->rho ^{+}K^{-}, bar{B}_{s}^{0}-> K^{*^{+}}K^{-} and bar{B}_{d}^{0}-> K^{*^{-}}pi ^{+}, bar{B}_{s}^{0}-> K^{*^{-}}K^{+} are expressed in terms of the decay parameters of bar{B}_{d}^{0}->rho ^{+}pi ^{-},rho ^{-}\\pi ^{+}. From the experimental data, we derive the bounds: 0.12leq r_{-,+}leq 0.28; 0.15\\leq r_{+,-}\\leq 0.38. Further in the range -0.18\\leq z_{-+,+-}leq -0.28 it is possible to get a solution delta _{-,+}=delta_{+,-}=pi -delta ^{prime} for 62^{o} geq delta ^{prime}geq 35^{o} and 53^{o}leq gamma leq 71^{o} However, for 0.25leq z_{+-}leq 0.45 and -0.45\\leq z_{-+}leq -0.25, we get a complementry solution delta_{-+}=pi -delta _{+-}; 50^{o}geq delta_{+-} geq 35^{o} ; 50^{o}leq gamma leq 71^{o}. Assuming factorization for electroweak penguin, we obtain the sum rule f_{rho }-(1/3)f_{omega}-(2/3)f_{phi}=0 which is well satisfied experimentally.

    Background Sleep disturbance in bipolar disorder can be both a risk factor and symptom of mood episodes. However, the associations among sleep and clinical characteristics, function, and quality of life in bipolar disorder have not been fully investigated. Methods The prevalence of sleep disturbance, duration, and variability, as well as their associations with mood, function, and quality of life, was determined from 2,024 bipolar patients enrolled in the National Institute of Mental Health Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD). Results Analyses indicated that 32% of patients were classified as short sleepers, 38% normal sleepers, and 23% long sleepers. Overall, short sleepers demonstrated greater mood elevation, earlier age at onset, and longer illness duration compared to both normal and long sleepers. Both short and long sleepers had greater depressive symptoms, poorer life functioning, and quality of life compared to normal sleepers. Discussion Short sleep duration in bipolar disorder was associated with a more severe symptom presentation, whereas both short and long sleep duration are associated with poorer function and quality of life compared to normal sleep duration. Sleep disturbance could be a trait marker of bipolar disorder, though longitudinal assessments are warranted to assess potential causal relations and the longer-term implications of sleep disturbance in bipolar disorder PMID:18707765

    LHCb is the dedicated flavour physics experiment of the LHC. The experiment is designed for probing new physics through measurements of CP violation and rare decays. This thesis includes simulation studies of the Bd ⇒ K*μ+μ- decay. The LHCb vertex locator (VELO) is the highest precision tracking detector at the LHC and is used to identify primary and secondary vertices for the identification of the $b$ and $c$ hadrons. The VELO modules contain silicon strip detectors which must be operated under reverse bias voltage. This thesis presents the work performed on the design, production and characterisation of the VELO high voltage system. The VELO operates only 8\\mm~from the LHC beam in a high radiation environment. A future upgrade will require operation at up to 10$^{16}$ n_{eq}cm^{-2}.This thesis presents a characterisation of p-type silicon sensors before and after heavy irradiations. The design of the HV system and the substantial programme of quality assurance tests performed on both the hardware and so...

    Sandy coastal sediments are global hot spots for microbial mineralization of organic matter and denitrification. These sediments are characterized by advective pore water flow, tidal cycling and an active and complex microbial community. Metagenomic sequencing of microbial communities sampled from such sediments showed that potential sulfuroxidizing Gammaproteobacteria and members of the enigmaticBD1-5/ SN-2 candidatephylumwereabundantinsitu (>10% and 2% respectively). By mimicking the dynamic oxic/anoxic environmental conditions of the sedimentin a laboratory chemostat, a simplified microbial community was selected from the more complex inoculum. Metagenomics, proteomics and fluorescenceinsituhybridization showed that this simplified community contained both a potential sulfuroxidizing Gamma proteobacteria (at 24 2% abundance) and a member of the BD1-5 / SN-2candidatephylum (at 7 6%abundance). Despite the abundant supply of organic substrates to the chemostat, proteomic analysis suggested that the selected gamma proteobacterium grew partially auto trophically and performed hydrogen/formate oxidation. The enrichment of a member of the BD1-5/SN-2candidatephylum enabled, for the first time, direct microscopic observation by fluorescent insitu hybridization and the experimental validation of the previously predicted translation of the stop codon UGA into glycine.

    Naturally produced by the human immune system, immunoglobulin nowadays is widely used for in vivo and in vitro purposes. The increased needs for pure immunoglobulin have prompted researchers to find new immunoglobulin chromatographic separation processes. Cryogels as chromatographic adsorbents, congregate several mechanical features including good compatibility, large pore structure, flexibility, short diffusion pathway and stability. These different characteristics make them a good alternative to conventional chromatographic methods and allowing their potential use in separation technology. In the present study, two sets of poly(2-hydroxyethyl methacrylate) (PHEMA) based beads were prepared and functionalized with Reactive Red 120 (RR) and Reactive Green HE 4BD (RG) dyes, and then embedded into supermacroporous cryogels. The morphology, physical and chemical features of the prepared bead embedded composite cryogel discs (CCDs) were performed by scanning electron microscopy (SEM), swelling test, elemental analysis and Fourier transform infrared spectroscopy (FTIR). The results showed that the embedded composite cryogel discs have a specific surface area of 192.0 m{sup 2}/g with maximum adsorption capacity of HIgG 239.8 mg/g for the RR functionalized CCD and 170 mg/g for RG functionalized CCD columns, both at pH 6.2. - Highlights: • Dye attached composite cryogel discs were prepared to separate HIgG subclasses. • Composite cryogels characterized by swelling, FTIR, SEM and elemental analysis. • Reactive Green HE 4B and Reactive Red 120 dyes were used as the affinity ligand. • HIgG and subclasses were separate from both aqueous solution and human plasma.

    Hexachlorocyclohexane (HCH) was among the most commonly used pesticides after the Second World War. The extensive use of this hydrocarbon for almost six decades has created a contamination problem on a global scale, and bioremediation methods are being extensively explored. The reported ability of some Devosia species to grow in the presence of appreciable amounts of hydrocarbons (2,000 mg/kg of contaminated soil) is attracting closer attention. Here, we report the de novo genome assembly of two hydrocarbon-tolerating Devosia isolates, D. chinhatensis strain IPL18(T) and D. geojensis strain BD-c194(T), as a first step toward understanding the metabolic pathways involved in their environmental adaptation and tolerance toward hydrocarbons.

    A new IR emission feature at 1905/cm (5.25 microns) has been discovered in the spectrum of BD + 30 deg 3639. This feature joins the family of well-known IR emission features at 3040, 2940, 1750, 1610, '1310', 1160, and 890/cm. The origin of this new feature is discussed and it is assigned to an overtone or combination band involving C-H bending modes of polycyclic aromatic hydrocarbons (PAHs). Laboratory work suggests that spectral studies of the 2000-1650/cm region may be very useful in elucidating the molecular structure of interstellar PAHs. The new feature, in conjunction with other recently discovered spectral structures, suggests that the narrow IR emission features originate in PAH molecules rather than large carbon grains.

    {delta} Sct-{gamma} Dor hybrids pulsate simultaneously in p- and g-modes, which carry information on the structure of the envelope as well as to the core. Hence, they are key objects for investigating A and F type stars with asteroseismic techniques. An important requirement for seismic modeling is small errors in temperature, gravity, and chemical composition. Furthermore, we want to investigate the existence of an abundance indicator typical for hybrids, something that is well established for the roAp stars. Previous to the present investigation, the abundance pattern of only one hybrid and another hybrid candidate has been published. We obtained high-resolution spectra of HD 114839 and BD +18 4914 using the SOPHIE spectrograph of the Observatoire de Haute-Provence and the HARPS spectrograph at ESO La Silla. For each star we determined fundamental parameters and photospheric abundances of 16 chemical elements by comparing synthetic spectra with the observations. We compare our results to that of seven {delta} Sct and nine {gamma} Dor stars. For the evolved BD +18 4914 we found an abundance pattern typical for an Am star, but could not confirm this peculiarity for the less evolved star HD 114839, which is classified in the literature as uncertain Am star. Our result supports the concept of evolved Am stars being unstable. With our investigation we nearly doubled the number of spectroscopically analyzed {delta} Sct-{gamma} Dor hybrid stars, but did not yet succeed in identifying a spectroscopic signature for this group of pulsating stars. A statistically significant spectroscopic investigation of {delta} Sct- {gamma} Dor hybrid stars is still missing, but would be rewarding considering the asteroseismological potential of this group.

    Oxygen equilibrium curves have been widely used to understand oxygen transport in numerous organisms. A major challenge has been to monitor oxygen binding characteristics and concomitant pH changes as they occur in vivo, in limited sample volumes. Here we report a technique allowing highly resolved and simultaneous monitoring of pH and blood pigment saturation in minute blood volumes. We equipped a gas diffusion chamber with a broad-range fibre-optic spectrophotometer and a micro-pH optode and recorded changes of pigment oxygenation along oxygen partial pressure (PO2) and pH gradients to test the setup. Oxygen binding parameters derived from measurements in only 15 μl of haemolymph from the cephalopod Octopus vulgaris showed low instrumental error (0.93%) and good agreement with published data. Broad-range spectra, each resolving 2048 data points, provided detailed insight into the complex absorbance characteristics of diverse blood types. After consideration of photobleaching and intrinsic fluorescence, pH optodes yielded accurate recordings and resolved a sigmoidal shift of 0.03 pH units in response to changing PO2 from 0 to 21 kPa. Highly resolved continuous recordings along pH gradients conformed to stepwise measurements at low rates of pH changes. In this study we showed that a diffusion chamber upgraded with a broad-range spectrophotometer and an optical pH sensor accurately characterizes oxygen binding with minimal sample consumption and manipulation. We conclude that the modified diffusion chamber is highly suitable for experimental biologists who demand high flexibility, detailed insight into oxygen binding as well as experimental and biological accuracy combined in a single setup.

    Misuse of gamma hydroxybutrate (GHB) and gamma butyrolactone (GBL) has increased greatly since the early 1990s, being implicated in a rising number of deaths. This paper reviews knowledge on GHB and derivatives, and explores the largest series of deaths associated with their non-medical use. Descriptive analyses of cases associated with GHB/GBL and 1,4-butanediol (1,4-BD) use extracted from the UK's National Programme on Substance Abuse Deaths database. From 1995 to September 2013, 159 GHB/GBL-associated fatalities were reported. Typical victims: White (92%); young (mean age 32 years); male (82%); with a drug misuse history (70%). Most deaths (79%) were accidental or related to drug use, the remainder (potential) suicides. GHB/GBL alone was implicated in 37%; alcohol 14%; other drugs 28%; other drugs and alcohol 15%. Its endogenous nature and rapid elimination limit toxicological detection. Post-mortem blood levels: mean 482 (range 0-6500; SD 758)mg/L. Results suggest significant caution is needed when ingesting GHB/GBL, particularly with alcohol, benzodiazepines, opiates, stimulants, and ketamine. More awareness is needed about risks associated with consumption.

    We have discovered a new IR emission feature at 1905 cm-1 (5.25 microns) in the spectrum of BD +30 degrees 3639. This feature joins the family of well-known IR emission features at 3040, 2940, 1750, 1610, "1310," 1160, and 890 cm-1 (3.3, 3.4, 5.7, 6.2, "7.7," 8.6, and 11.2 microns). The origin of this new feature is discussed and it is assigned to an overtone or combination band involving C-H bending modes of polycyclic aromatic hydrocarbons (PAHs). Laboratory work suggests that spectral studies of the 2000-1650 cm-1 (5.0-6.1 microns) region may be very useful in elucidating the molecular structure of interstellar PAHs. The new feature, in conjunction with other recently discovered spectral structure, suggests that the narrow IR emission features originate in PAH molecules rather than large carbon grains. Larger species are likely to be the source of the broad underlying "plateaus" seen in many of the spectra.

    The performance of a nested PCR-based assay (the RAPID BAP-MTB; AsiaGen, Taichung, Taiwan) and the BD ProbeTec ET (DTB) system (Becton Dickinson, Sparks, Md.) for detection of Mycobacterium tuberculosis was evaluated with 600 consecutive clinical samples. These samples, including 552 respiratory specimens and 48 nonrespiratory specimens, were collected from 333 patients treated at National Taiwan University Hospital from September to October 2003. The results of both assays were compared to the gold standard of combined culture results and clinical diagnosis. The overall sensitivity and specificity of the RAPID BAP-MTB assay for respiratory specimens were 66.7% and 97.2%, respectively, and for the DTB assay they were 56.7% and 95.3%, respectively. The positive and negative predictive values for the RAPID BAP-MTB were 74.1% and 96.0%, respectively, and for the DTB assay they were 59.6% and 94.7%, respectively. For smear-negative samples, the sensitivity of the RAPID BAP-MTB and DTB assays was 57.1% and 40.5%, respectively. The RAPID BAP-MTB assay produced 14 false-positive results in 14 samples, including one of the six samples yielding Mycobacterium abscessus, one of the six samples yielding Mycobacterium avium intracellulare, one sample from a patient with a history of pulmonary tuberculosis with complete treatment, and three samples from three patients with a previous diagnosis of tuberculosis who were under treatment at the time of specimen collection. Among the 48 nonrespiratory specimens, the RAPID BAP-MTB assay was positive in one biopsy sample from a patient with lumbar tuberculous spondylitis and one pus sample from a patient with tuberculous cervical lymphadenopathy. Our results showed that the RAPID BAP-MTB assay is better than the DTB assay for both respiratory specimens and nonrespiratory specimens. The overall time for processing this assay is only 5 h. In addition, its diagnostic accuracy in smear-negative samples is as high as in smear

The Veritor and Binax tests demonstrated negative percent agreements >97.9% for detection of both influenza viruses, but the negative percent agreement of the Sofia test was 91.1% for influenza A and 70.7% for influenza B virus. Overall, the Veritor and Sofia tests were nearly as sensitive as RT-PCR and considerably more sensitive than Binax for detection of influenza viruses. However, the accuracy of the Sofia test was significantly lower than either Veritor or Binax. PMID:24582581

    It is important to determine a critical micelle concentration (CMC) of a surfactant in a protein formulation for stabilizing the protein at maximum by preventing it from interfacial denaturation. There are several techniques for CMC determination. Among them, surface tensiometry is the most common approach because this has a long history and much data at many research fields. However, large amount of sample solution is usually required for the measurement (e.g., more than 1 mL is necessary when a standard reservoir like a glass petri dish is used). This is one of the hurdles for protein formulators because only a small amount of protein could be used at the early-stage development. In this research, we tried to minimize the required amount of sample solution for surface tension measurement by developing appropriate probe and reservoir using a three-dimensional printer (3D printer). The advantages and capabilities of 3D printer are (1) to control the shape and size of the printed material precisely, (2) to change the figure freely, and (3) to prepare the prototype quickly. After the experiments and thereby the refinement of probe as well as reservoir, we found that CMCs of polysorbate 20, polysorbate 80, and poloxamer 188 in water and protein formulations could be precisely detected using a probe 0.5 mm in diameter and small reservoir with a pocket of 7.5 mm in diameter/0.25 mm in depth which were made by a 3D printer. Furthermore, the required sample solution per each measurement could be reduced to 80 μL, which means more than 90% reduction against a standard reservoir. PMID:27321235

    We have explored use of perfused regenerated cellulose (RC) microdialysis tubing (216microm o.d./200microm i.d.) as sampling probes for gaseous ammonia. The probes functioned by allowing the gas to diffuse through the permeable membrane into a stream of de-ionized water which continually perfused the tubing at 10-20microLmin(-1). The resulting ammonium in the perfusate was determined through a fluorimetric method (OPA-sulfite) with LED excitation at lambda(ex)=365+/-10nm and measurement of fluorescence emission at lambda(em)=425+/-20nm. By shielding the sampling membrane with a Plexiglas tube purged under laminar flow conditions, the potential interference of particulate ammonium depositing on the probe was minimized. The RC microdialysis tube was found to act as an efficient sampling device since it exhibits a very high surface-area-to-volume ratio (approximately 200cm(2)mL(-1)). As a result, aqueous concentrations of >100microM NH(4)(+) per ppm NH(3) (g) have been observed. In addition, the fluorogenic OPA-sulfite reaction is demonstrated to be very selective for ammonia over amines that have been measured in the atmosphere. This feature of the derivatization chemistry allows analysis of ammonia by fluorimetry without need for a separation step. The method developed has been applied to field measurements of ammonia at a swine barn facility with quantitative results agreeing with a reference method.

    We introduce a novel manifold and companion software for dipstick urinalysis that eliminate many of the aspects that are traditionally plagued by user error: precise sample delivery, accurate readout timing, and controlled lighting conditions. The proposed all-acrylic slipping manifold is reusable, reliable, and low in cost. A simple timing mechanism ensures results are read out at the appropriate time. Results are obtained by capturing videos using a mobile phone and by analyzing them using custom-designed software. We show that the results obtained with the proposed device are as accurate and consistent as a properly executed dip-and-wipe method, the industry gold-standard, suggesting the potential for this strategy to enable confident urinalysis testing in home environments.

    The Laboratory of Viral Diseases Immunology (Laboratoire d'Immunologie des Maladies Virales) of the Northern Region Blood Bank (Etablissement Français du Sang Nord de France) performs between 180.000 and 200.000 viral blood qualifications per year. The use of a serum gel separator evacuated tube should contribute to improve the quality of the pre-analytical phase. However, it must not impact negatively the analytical performances. We evaluated such tube within our specific environment and with the various reagents used in routine. The open study compared the BD Vacutainer plain tube (7 mL, non siliconised) with the BD Vacutainer SST tube (6 mL siliconised with serum gel separator) against the anti-HIV, anti-HTLV, anti-HCV, anti-HBc, anti-HBs, anti-CMV antibodies, the HBs, HIV P24 antigen and the alanine aminotransferase. The study objectives were to find potential gel interference; to verify the diagnostic sensitivity, reagents specificity, and reproducibility. The results analysis show: equivalent performances with the anti-HIV Ab (Anti HIV 1/2 recombinant--Biotest et Genscreen HIV 1/2--Sanofi), anti HIV WB Ab (New Lav Blot 1--Sanofi), anti-HBs Ab (Enzygnost anti-HBs micro--Behring), anti-HBc Ab (HBc Elisa Test System--Ortho), anti-CMV Ab (Enzygnost anti-CMV IgG + M--Behring) kits; lower performances with: The Vironostika HIV Uni Form II plus 0--Organon kit with a -3.5% signal decrease around the ratio R = 2.7 for positive anti-HIV Ab. The Elisa test System 3 Ag HBs-Ortho kit with an increase of the mean ratio of the negative Ag HBs samples; better performances with: the Vironostika HIV 1 Antigen--Organon kit with a +10% signal increase around the threshold ratio R = 1 for positive Ag HIV samples. This deserves further study to verify that the specificity is maintained. The HTLV Type 1 et 2 EIA--Ortho kit with +8% signal increase around the ratio R = 2 for positive anti-HTLV Ab samples without change of the specificity. The Ortho HCV 3.0 Elisa Test System and

    L'analyse temporelle du correlogramme de Dalitz du canal a trois corps Bd en pi+ pi- pi0 conduit a l'extraction de l'un des parametres definissant la violation de la symetrie CP dans le Modele Standard Electrofaible, l'angle alpha, exempte d'ambiguites discretes entre 0 et pi. Elle permet, entre autres, d'acceder independamment aux valeurs des principaux parametres QCD regissant la desintegration. La contrepartie experimentale repose cependant sur une statistique de signal suffisamment pure et importante et une maitrise precise de la phenomenologie associee. Combines a un rapport d'embranchement de l'ordre de 2.10^{-5}, ces deux arguments justifient a eux seuls le caractere non trivial d'une telle analyse dans l'environnement hadronique de l'experience dediee LHCb. A partir de la reponse simulee du detecteur, et en particulier des performances du calorimetre electromagnetique, cette these montre l'interet essentiel de la reconstruction specifique des pions neutres tres energiques et la necessite d'introduire ...

    We estimate $\\dg/\\Gamma_d$, including $1/m_b$ contributions and part of the next-to-leading order QCD corrections. We find that adding the latter corrections decreases the value of $\\dg/\\Gamma_d$ computed at the leading order by a factor of almost 2. We also show that under certain conditions an upper bound on the value of $\\dg/\\Gamma_d$ in the presence of new physics can be derived. With the high statistics and accurate time resolution of the upcoming LHC experiment, the measurement of $\\dg$ seems to be possible. This measurement would be important for an accurate measurement of $\\sin(2\\beta)$ at the LHC. In addition, we point out the possibility that the measurement of the width difference leads to a clear signal for new physics.

    We present an abundance analysis of the star Cernis 52 in whose spectrum we recently reported the napthalene cation in absorption at 6707.4 {\\AA}. This star is on a line of sight to the Perseus molecular complex. The analysis of high-resolution spectra using a chi^2-minimization procedure and a grid of synthetic spectra provides the stellar parameters and the abundances of O, Mg, Si, S, Ca, and Fe. The stellar parameters of this star are found to be T_{eff} = 8350 +- 200 K, logg= 4.2 +- 0.4 dex. We derived a metallicity of [Fe/H] = -0.01 +- 0.15. These stellar parameters are consistent with a star of $\\sim 2$ \\Msun in a pre-main-sequence evolutionary stage. The stellar spectrum is significantly veiled in the spectral range 5150-6730 {\\AA} up to almost 55 per cent of the total flux at 5150 {\\AA} and decreasing towards longer wavelengths. Using Johnson-Cousins and 2MASS photometric data, we determine a distance to Cernis 52 of 231$^{+135}_{-85}$ pc considering the error bars of the stellar parameters. This dete...

    We report on a measurement of the $B^0_d$ mixing frequency and the calibration of an opposite-side flavor tagger in the D{\\O}experiment. Various properties associated with the $b$ quark on the opposite side of the reconstructed $B$ meson were combined using a likelihood-ratio method into a single variable with enhanced tagging power. Its performance was tested with data, using a large sample of reconstructed semileptonic $B \\to \\mu \\dzero X$ and $B \\to \\mu \\dst X$ decays, corresponding to an integrated luminosity of approximately 1 fb$^{-1}$. The events were divided into groups depending on the value of the combined tagging variable, and an independent analysis was performed in each group. Combining the results of these analyses, the overall effective tagging power was found to be eD^2 = (2.48 \\pm 0.21 (stat.) ^{+0.08}_{-0.06} (syst.))%. The measured $B^0_d$ mixing frequency dmd = 0.506 \\pm 0.020 {\\rm (stat) \\pm 0.016 (syst) ps}^{-1} is in good agreement with the world average value.

    HR-CS-GFAAS methods were developed for the fast determination of Cu in domestic and commercially available Hungarian distilled alcoholic beverages (called pálinka), in order to decide if their Cu content exceeds the permissible limit, as legislated by the WHO. Some microliters of samples were directly dispensed into the atomizer. Graphite furnace heating programs, effects/amounts of the Pd modifier, alternative wavelengths (e.g., Cu I 249.2146nm), external calibration and internal standardization methods were studied. Applying a fast graphite furnace heating program without any chemical modifier, the Cu content of a sample could be quantitated within 1.5min. The detection limit of the method is 0.03mg/L. Calibration curves are linear up to 10-15mg/L Cu. Spike-recoveries ranged from 89% to 119% with an average of 100.9±8.5%. Internal calibration could be applied with the assistance of Cr, Fe, and/or Rh standards. The accuracy of the GFAAS results was verified by TXRF analyses. PMID:27451250

  12. Preliminary results from a microvolume, dynamically heated analytical column for preconcentration and separation of simple gases prior to stable isotopic analysis

    Stable isotope applications that call for preconcentration (i.e., greenhouse gas measurements, small carbonate samples, etc.) universally call for cryogenic fluids such as liquid nitrogen, dry ice slurries, or expensive external recirculation chillers. This adds significant complexity, first and foremost in the requirements to store and handle such dangerous materials. A second layer of complexity is the instrument itself - with mechanisms to physically move either coolant around the trap, or move a trap in or out of the coolant. Not to mention design requirements for hardware that can safely isolate the fluid from other sensitive areas. In an effort to simplify the isotopic analysis of gases requiring preconcentration, we have developed a new separation technology, UltiTrapTM (patent pending), which leverage's the proprietary Advanced Purge & Trap (APT) Technology employed in elemental analysers from Elementar Analysensysteme GmbH products. UltiTrapTM has been specially developed as a micro volume, dynamically heated GC separation column. The introduction of solid-state cooling technology enables sub-zero temperatures without cryogenics or refrigerants, eliminates all moving parts, and increases analytical longevity due to no boiling losses of coolant . This new technology makes it possible for the system to be deployed as both a focussing device and as a gas separation device. Initial data on synthetic gas mixtures (CO2/CH4/N2O in air), and real-world applications including long-term room air and a comparison between carbonated waters of different origins show excellent agreement with previous technologies.

    Balm, Paul W

    2004-12-01

    This thesis describes a measurement of the B{sub d}{sup 0} lifetime in the decay to (J/{psi}K{sub S}{sup 0}), using 114 pb{sup -1} of data collected by the D0 experiment at the Tevatron from October 15, 2002, to June 10, 2003. The measurement is motivated by the tests of the Standard Model that it makes possible. These include tests of Heavy Quark Effective Theory predicting B-meson lifetimes, and of the complex phase in the CKM-matrix as the source of CP-violation in B{sub d}{sup 0} decays to (J/{psi}K{sub S}{sup 0}).

    Full Text Available This paper provides a commentary and translation of two contrafacta of Arnaut Daniel’s sestina: Guilhem de Saint Gregori’s "Ben gran avolesa intra" and Bartolomeo Zorzi’s "En tal dezir mos cors intra". For the first song, I will highlight the new contexts and meanings given to Arnaut’s images (which are taken from his sestina and other poems within Guilhem’s invective against Aimers II of Poitiers, in order to evaluate its literary qualities and innovations. Through lexical analysis, this paper will reveal the strong connection between Zorzi’s and Guilhem’s songs. In particular, the paper analyses specifically their common theme of Hell, suggesting Bartolomeo’s text is most likely an answer to Arnaut’s sestina, which clearly expresses a desire of sensual pleasure. The study pays particular attention to the relation between sexual love and the matter of eternal damnation: Zorzi attacks Arnaut’s ferm voler, advancing his argument by evoking Chrétien de Troyes’ "Perceval" (references to which are spread throughout the text, and not only in l. 18 and through his constant stress on the duties towards one’s family.

  9. Raimbaut de Vaqueiras, “Domna, tant vos ai prejada” (BdT 392.7

    Gilda Caiti-Russo

    2009-12-01

    Full Text Available This paper will attempt to read Raimbaut de Vaqueiras’ ‘contrasto’ from the viewpoint of its explicit addressees: the late twelfth-century imperial nobility of north-western Italy, as embodied by the Malaspina family. The text’s distinctive bilingualism thus assumes social and political significance since it pits the claims of the feudal aristocracy of the hinterland against the power of the Genoese bankers and merchants. The dialectical relationship of the two sides involved, played out by the voices of the jongleur and the Genoese lady, is nevertheless also literary: Raimbaut appears to match popular poetry, poetry which is «non regulata» as Dante would later call it, against a century of courtly Occitan poetry distinguished by an extremely formal tradition. A carnivalesque dimension is thus present in the reciprocal illumination of the two poetic voices: if popular poetry is unregulated despite its expressive qualities, troubadour poetry is confined, by means of the parody of the genre of the ‘salut’, to topics far-removed from reality. Raimbaut’s aim then is to restructure trobar by going back to the beginning: to the Count of Poitiers and his political and cultural act of inventing a secular poetry of aristocratic inspiration and in the vernacular. A ‘male’ poetry that will be formulated by the surprising gap at the end of the poem.

    The world's genomics data will never be stored in a single repository - rather, it will be distributed among many sites in many countries. No one site will have enough data to explain genotype to phenotype relationships in rare diseases; therefore, sites must share data. To accomplish this, the genetics community must forge common standards and protocols to make sharing and computing data among many sites a seamless activity. Through the Global Alliance for Genomics and Health, we are pioneering the development of shared application programming interfaces (APIs) to connect the world's genome repositories. In parallel, we are developing an open source software stack (ADAM) that uses these APIs. This combination will create a cohesive genome informatics ecosystem. Using containers, we are facilitating the deployment of this software in a diverse array of environments. Through benchmarking efforts and big data driver projects, we are ensuring ADAM's performance and utility. PMID:26174866

  11. Probing new physics in electroweak penguins through Bd and Bs decays

    Science.gov (United States)

    Hofer, Lars; Scherer, Dominik; Vernazza, Leonardo

    2011-12-01

    An enhanced electroweak penguin amplitude due to the presence of unknown new physics can explain the discrepancies found between theory and experiment in the B → πK decays, in particular in ACP(B- → π0K-) - ACP(bar B0 → π+K-), but the current precision of the theoretical and experimental results does not allow to draw a firm conclusion. We argue that the bar Bs → phiρ0 and bar Bs → phiπ0 decays offer an additional tool to investigate this possibility. These purely isospin-violating decays are dominated by electroweak penguins and we show that in presence of a new physics contribution their branching ratio can be enhanced by about an order of magnitude, without violating any constraints from other hadronic B decays. This makes them very interesting modes for LHCb and future B factories. In [1] we have performed both a model-independent analysis and a study within realistic New Physics models such as a modified-Z0-penguin scenario, a model with an additional Z' boson and the MSSM. In this article we summarise the most important results of our study.

    We present a preliminary study of $B^- \\to D^0_{CP} \\pi^-$ and $B^- \\to D^0_{CP} K^-$ decays, with the $D^0_{CP}$ reconstructed in the CP-odd eigenstates $K_s \\pi^0$, $K_s \\omega$, in the CP-even eigenstates $K^+ K^-$, $\\pi^+ \\pi^-$, and in the (non-CP) flavor eigenstate $K^\\mp \\pi^\\pm$. Using a sample of about 382 million Y(4S) decays into BBbar pairs, collected with the BABAR detector operating at the PEP-II asymmetric-energy B Factory at SLAC, we measure the ratios of the branching fractions R_CP+- and the direct CP asymmetries A_CP+-. The results are: R_CP- = 0.81 \\pm 0.10 (stat) \\pm 0.05 (syst) R_CP+ = 1.07 \\pm 0.10 (stat) \\pm 0.04 (syst) A_CP- = -0.19 \\pm 0.12 (stat) \\pm 0.02 (syst) A_CP+ = 0.35 \\pm 0.09 (stat) \\pm 0.05 (syst)

    We discuss the large set of observables available from the angular distributions of the decay {bar B}{sub d} {yields} {bar K}*{sup 0}{ell}{sup +}{ell}{sup -}. We present a NLO analysis of all observables based on the QCD factorization approach in the low-dilepton mass region and an estimate of {Lambda}/m{sub b} corrections. Moreover, we discuss their sensitivity to new physics. We explore the experimental sensitivities at LHCb (10 fb{sup -1}) and SuperLHCb (100 fb{sup -1}) based on a full-angular fit method and explore the sensitivity to right handed currents. We also show that the previously discussed transversity amplitude A{sub T}{sup (1)} cannot be measured at the LHCb experiment or at future B factory experiments as it requires a measurement of the spin of the final state particles.

  17. Probing new physics in electroweak penguins through B_d and B_s decays

    CERN Document Server

    Hofer, Lars; Vernazza, Leonardo

    2011-01-01

    An enhanced electroweak penguin amplitude due to the presence of unknown new physics can explain the discrepancies found between theory and experiment in the B -> pi K decays, in particular in A_CP(B^- -> pi^0 K^-) - A_CP(\\bar{B}^0 -> pi^+ K^-), but the current precision of the theoretical and experimental results does not allow to draw a firm conclusion. We argue that the \\bar{B}_s -> phi rho^0 and \\bar{B}_s -> phi pi^0 decays offer an additional tool to investigate this possibility. These purely isospin-violating decays are dominated by electroweak penguins and we show that in presence of a new physics contribution their branching ratio can be enhanced by about an order of magnitude, without violating any constraints from other hadronic B decays. This makes them very interesting modes for LHCb and future B factories. In arXiv:1011.6319 we have performed both a model-independent analysis and a study within realistic New Physics models such as a modified-Z^0-penguin scenario, a model with an additional Z' bos...

    N-hexadecyl-p-cyanopyridinium iodide was studied using X-ray scattering, differential scanning calorimetry and polarized light microscopy. Preliminary results reveal that the material is thermochromic, turning from yellow to red upon entering a liquid crystal phase at 104°C. The mesophase is of the smectic B type, where the lamellar spacing is between one and two molecular lengths. A structural model is proposed that can be described as a honeycomb arrangement of unpaired molecules with their...

  19. Evaluating the BD-100R as a neutron spectrometer through pressure variation

    Investigators have evaluated the dose response of neutron bubble dosimeters for possible use as a personnel monitor. In addition, two types of neutron spectrometer devices using bubble dosimetry have been developed. One uses the variation of vapor pressure of mixtures of detection material to extract the neutron energy spectrum, while the other employs variation of applied pressure on a different material. Dosimeter response changes due to variation of applied pressure have been demonstrated by Ing and Birnboim at absolute pressures of 0.432 MPa and atmospheric pressure. This investigation is intended to demonstrate the determination of an unknown spectrum utilizing the dosimeter response (number of bubbles formed) as a function of the applied pressure.

    Full Text Available The aim of this paper is to study the use of the senhal Bonafos, that occurs in l. 27 of the partimen between Cavaire and Bonafos, as a satirical-parodic senhal. We propose to analyse Bonafos in the same way as we previously examined the use of its opposite, Malafos, in contexts containing a discourse that is far from that of the Canso. This would be the case of the pastorela and the partimen. The use of an echoing irony and its interaction with parody and satire would have made possible the conversion of a previous discursive modalizer into a satirical-parodic senhal in this partimen. We also take into account the use that Jews from the south of France made of the anthroponym Bonafos. The conclusions from previous works as well as the data deriving from the Geopatronyme have provided us with this interesting information. However, we do not believe that in this partimen Bonafos is the real name of the jongleur. On the contrary, we argue that Bonafos, even if an anthroponym, might have continued to ‘encapsulate’ the echo of its hypothetical origin: the discursive modalizer (anc bona fos.

    Emendoerfer, D.; Hoecker, K.H.

    1982-01-01

    An introduction is given to the elements of reactor physics and reactor calculation which refers to practice from the present point of view. It is demonstrated to the reader how the reactor characteristics relevant to construction can be calculated from atomic factors by means of neutron transport and diffusion theory; these reactor characteristics are: multiplication factor, power density distribution, burn-up, plutonium build-up, xenon vibrations, short-time behaviour. The interaction between thermo- and fluid-dynamic processes is important for this calculation. On grounds of didactics the crucial point of this book is the establishment and calculation of simple models which give a clear description of all important characteristics of the events. Attempts for more exact simulation by computer are dealt with including typical solutions.

    Diagnostic radiology in emergency patients as a supplement to anamnesis and examination has gained increasing importance in the last few years. Usually, the physician in charge has only few signs to go by when a patient is sent to radiology. The most frequent signs are pectoral pain, headache, dyspenea, etc. The cases in this book have been selected accordingly. Although the names have been invented the case histories presented have not been greatly changed. The original 'negatives' of the anamnesis are not presented in most cases as they would have taken up too much space. No important information has been omitted. A typical and unusual cases are characterized as such.

    Near-Earth Object Human Space Flight Accessible Targets Study(NHATS): http://neo.jpl.nasa.govnhats/. As of mid-July 2015: 1,434 of the 12,778 currently known NEAs are more astrodynamically accessible than is Mars (requiring less Delta v and or less flight time for round-trip missions). Within those 1,434 NEAs: 605 NEAs can be visited round-trip for less Delta v (9 km/s) than the lunar surface. 51 NEAs can be visited round-trip for less v (5 km/s) than low circular lunar orbit. NEO population statistical models:Tens of thousands of NEAs greater than 100 m yet to be discovered. At least several million NEAs less than or equal to100 m in size (down to approximately 3 m in size) yet to be discovered. How accessible are the NEAs that haven't yet been discovered?

  18. Peire Vidal, “Bon’aventura don Dieus als Pizas” (BdT 364.14

    Directory of Open Access Journals (Sweden)

    Marco Grimaldi

    2013-05-01

    Full Text Available The poem examined here, probably composed in Italy, is mainly known for its historical interest and as a satire of the Germans. In “Bon’aventura”, in fact, Peire Vidal seems to be siding openly with the Marquis Boniface I of Monferrato and the Lombard communes, that were at war with the Emperor Henry IV, who had invaded Italy at the end of 1194. This paper, which reproduces Avalle’s edition and basically confirms the usual date between autumn 1194 and April 1195, will discuss the precise relationship between poetry and politics in Peire Vidal’s work through an analysis of the song’s value as a document in relation to contemporary sources. Thus it will examine the troubadour’s attitude to the events of his day and attempt to outline a fluid and ‘regional’ political loyalty which the poet from Toulouse shares with his contemporaries.

  19. Chemical Characterization of an Envelope B/D Sample from Hanford Tank 241-AZ-102

    International Nuclear Information System (INIS)

    A sample from Hanford waste tank 241-AZ-102 was received at the Savannah River Technology Center (SRTC) and chemically characterized. The sample containing supernate and a small amount of sludge solids was analyzed as-received. The filtered supernatant liquid, the total dried solids of the sample, and the washed insoluble solids obtained from filtration of the sample were analyzed. A mass balance calculation of the three fractions of the sample analyzed indicate the analytical results appear relatively self-consistent for major components of the sample. However, some inconsistency was observed between results were more than one method of determination was employed and for species present in low concentrations. The actinides isotopes, plutonium, americium, and curium, present analytical challenges due to the low concentration of these species and the potential for introduction of small amounts of contamination during sampling handling resulting in large uncertainties. A direct comparison to previous analyses of material from tank 241-AZ-102 showed good agreement with the filtered supernatant liquid. However, the comparison of solids data showed poor agreement. The poor agreement shown between the current results for the solids samples and previous analyses most likely results from the uncertainties associated with obtaining small solids samples from a large non-homogenized waste tank

    A new approach is presented in this paper by using dispersed TiO2 nanoparticles (TiO2-NPs) in a combined cloud point and solid phase extraction for the efficient preconcentration and determination of Zn(2+) in various samples. In this method Zn(2+) ions are adsorbed on TiO2-NPs and transferred into surfactant rich phase. Subsequently the Zn(2+) ions are desorbed from TiO2-NPs by a dithizone solution via forming a color complex which could be detected colorimetrically. The influence of chemical variables such as pH of the sample solution, electrolyte, amount of TiO2-NPs, type and volume of the eluent on the extraction system was studied. The calibration graph was linear in the range of 0.5-90.0 µg L(-1) of Zn(2+) (r=0.9996). An enrichment factor of 80 was achieved and the limit of detection for Zn(2+) was 0.33 µg L(-1). The relative standard deviation (RSD) for eight replicate measurements of 10 µg L(-1) and 60 µg L(-1) of Zn(2+) was 1.8% and 1.5% respectively. The proposed method was successfully applied to the quantitative determination of Zn(2+) in tap water, powder milk and Zinc sulfate tablet with satisfactory results. PMID:25059144

    2010-11-01

    Full Text Available This paper will put forward some possible new interpretations for selected passages in “Ab la douzor del temps novel” by William of Aquitaine. The term ‘vers’, for example, has always been paraphrased in different ways, but its primary meaning might be that provided by the naturalistic context: in the spring birds twitter among the branches, they produce a ‘verse’. Thus the literal meaning of ‘vers’ could be that of ‘a characteristic sound produced by the vocal organs of a particular animal (mainly a bird’. As for l. 15, instead of the traditional image of the hawthorn branch ‘tremblan’ (‘trembling’ on the tree, the alternative reading entrenan (the branch ‘stands firmly on the tree’, ‘resists the elements’ is preferred, which could well be a lectio difficilior. The paper will end by providing a commentary to the text. The edition used is Eusebi, with some corrections.

  7. Ricau de Tarascon ~ Cabrit, “Cabrit, al meu veiaire” (BdT 422.2 = 105.1

    Directory of Open Access Journals (Sweden)

    Walter Meliga

    2008-06-01

    Full Text Available The article provides a commentary and a new critical edition of an Occitan tenso between Ricau de Tarascon and Cabrit. The latter, previously identified with the troubadour Gui de Cavaillon, is now generally believed to be a noble man from Arles. Built as a judicial duel, the tenso is started by Ricau who accuses Cabrit of misconduct in his regards. Cabrit’s defense is based on comic ordeals, which are rejected by Ricau, who aims instead for a resolution of the conflict by combat. This dispute probably was caused by real private controversies that arose between two landowners, though in the tenso allusions to two ladies romantically involved with them, as well as the jongleuresque tone of the entire dialogue poem, transpose their conflict into a courtly and somehow ironic context.

    Paolo Di Luca

    2010-08-01

    Full Text Available “Ma bella dompna per vos dei esser gais” by Falquet de Romans has been taken for a courtly song for a long time. However, the poem’s metrical form is derived directly from that of the epic, as illustrated by the use of monorhymed ‘décasyllabes’ with non-systematic epic caesura and the presence of a ‘petit vers’ at the end of each stanza. The poem may thus be defined as stanzaic but not lyric because its versification is that of the chanson de geste and its music must be that of an epic chant. Moreover, its content reflects the rhetorical structure of the ‘salut d’amor’, an epistolary genre in which the lover sends a letter to his lady asking her to respond to his love. Thus, “Ma bella dompna” should be considered a formal hybrid between ‘salut d’amor’ and ‘chanson de geste’; in this sense it is to be compared to those few compositions of an epistolary nature that employ epic form, such as Raimbaut de Vaqueiras’ famous letter to the Marquis Boniface of Monferrato, which is probably the prototype of this poetic experiment, along with two pairs of ‘laisses’ exchanged between Gui de Cavaillon and Bertran Folco d’Avignon.

    This handbook was prepared primarily with the aim to provide information to experts in industry, authorities or research facilities engaged in criticality-safety-related problems that will allow an adequate and rapid assessment of criticality safety issues already in the planning and preparation of nuclear facilities. However, it is not the intention of the authors of the handbook to offer ready solutions to complex problems of nuclear safety. Such questions have to remain subject to an in-depth analysis and assessment to be carried out by dedicated criticality safety experts. Compared with the previous edition dated December 1998, this handbook has been further revised and supplemented. The proven basic structure of the handbook remains unchanged. The handbook follows in some ways similar criticality handbooks or instructions published in the USA, UK, France, Japan and the former Soviet Union. The expedient use of the information given in this handbook requires a fundamental understanding of criticality and the terminology of nuclear safety. In Vol. 1, ''Criticality and Nuclear Safety'', therefore, first the most important terms and fundamentals are introduced and explained. Subsequently, experimental techniques and calculation methods for evaluating criticality problems are presented. The following chapters of Vol. 1 deal i. a. with the effect of neutron reflectors and absorbers, neutron interaction, measuring methods for criticality, and organisational safety measures and provide an overview of criticality-relevant operational experience and of criticality accidents and their potential hazardous impact. Vol. 2 parts 1 and 2 finally compile criticality parameters in graphical and tabular form. The individual graph sheets are provided with an initially explained set of identifiers, to allow the quick finding of the information of current interest. Part 1 includes criticality parameters for systems with {sup 235}U as fissile material, while part 2 deals with systems comprising {sup 233}U, plutonium and higher actinides.

    Directory of Open Access Journals (Sweden)

    Francesco Carapezza

    2012-06-01

    Full Text Available The attribution of this love song to the troubadour from Rouergue, Daude de Pradas, according to the only Occitan testimony, i.e. song-book C, was considered impossible or at least suspicious by many scholars for the mere fact that its first verse is quoted, as a ‘chançon auvrignace’, in the “Roman de la Rose” (or Guillaume de Dole attributed to Jean Renart and initially dated to the earliest years of the XIIIth century. However, in the light of the recent dating of Daude’s poetic activity between 1191 and 1242, the chronological criterion alone cannot resolve the issue of attribution. This paper, where a more conservative edition of the text than that by C. Appel (1890 is proposed, will now present for the first time codicological – i.e. order and sources of Daude’s section in Ms. C – as well as metrical, stylistic and musical data, on the basis of the notation present in Ms. W. The discussion leads to the hypothesis that the song might be the work of an author belonging to the group of Marcabru’s imitators and therefore relatively early (third quarter of the XIIth century, setting aside the isolated attribution to Daude de Pradas.

    Under this contract, Bechtel analyzed the resource requirements and reviewed major obstacles to the daily production of several million barrels of synthetic coal liquids. Further, the study sought to identify the industry infrastructure needed to support the commercial readiness of the coal liquefaction process. A selected list of critical resource items and their domestic/international availability was developed and examined, and the impact of their supply on the various synthetic coal liquids programs was evaluated. The study approach was to develop representative, or generic, direct and indirect coal liquefaction conceptual designs from available technology and costs data. The generic processes were to employ technology that would be considered commercial by the mid- or late-1980s. The size of the generic construction mobilization was considered reasonable at the outset of the program. The product slate was directed toward unrefined liquid fuels rather than diesel oil or gasoline. The generic processes were to use a wide range of coals to permit siting in most coal-producing regions across the country. Because of the dearth of conceptual design data in the literature, Bechtel developed generic plant designs by using in-house design expertise. Bechtel assumed that because it is first generation technology, the indirect process will be used at the outset of the liquids program, and the direct process will be introduced two to four years later as a second generation technology. The products of either of these processes will be limited to boiler fuels and/or other liquid products which require further upgrading. Cost estimates were developed from equipment lists, as well as material and labor estimates, which enabled the determination of an order-of-magnitude cost estimate and target plant construction schedule for both processes.

    Marco Grimaldi

    2008-12-01

    Full Text Available The rubric in Chansonnier Sg classifies “Entr’Arago e Navarra jazia” by Cerveri de Girona as a ‘sompni’ (‘dream’. Thirteenth-century Occitan and Catalan arts of poetry define the ‘sompni’ as a minor thematic genre in which the poet recounts events which took place in a dream (“en durmen”. On the basis of the rubric in Sg and the definition in the treatises, the only hints at the existence of the genre, this paper will outline a small corpus of five/six troubadour poems based on the narration of a dream and significant examples of ‘sompni’. The hypothesis that a ‘genre’ defined as sompni exsisted and circulated beyond Occitania is furthermore linked to similar compositions by Paolo Lanfranchi, a thirteenth-century poet from Pistoia, and to some ‘cantigas de amigo’ by Johan Mendiz de Briteyros, a Galician-Portuguese troubadour. The paper will also seek to demonstrate the loss of a line in the final stanza, so far unnoticed by previous editors, and suggest a date for the poem around 1276.

    The fundamental physical quantity for relating all biologic effects to radiation exposure is the absorbed dose, the energy imparted per unit mass of tissue. Absorbed dose is expressed in units of joules per kilogram (J/kg) and is given the special name gray (Gy). Exposure to ionizing radiation may cause both deterministic and stochastic biologic effects. To account for the relative effect per unit absorbed dose that has been observed for different types of radiation, the International Commission on Radiological Protection (ICRP) has established radiation weighting factors for stochastic effects. The product of absorbed dose in Gy and the radiation weighting factor is defined as the equivalent dose. Equivalent dose values are designated by a special named unit, the sievert (Sv). Unlike the situation for stochastic effects, no well-defined formalism and associated special named quantities have been widely adopted for deterministic effects. The therapeutic application of radionuclides and, specifically, -particle emitters in nuclear medicine has brought to the forefront the need for a well-defined dosimetry formalism applicable to deterministic effects that is accompanied by corresponding special named quantities. This commentary reviews recent proposals related to this issue and concludes with a recommendation to establish a new named quantity.

    1994-02-01

    The Salt Lake City Area Office of the Western Area Power Administration (Western) markets electricity produced at hydroelectric facilities operated by the Bureau of Reclamation. The facilities are known collectively as the Salt Lake City Area Integrated Projects (SLCA/IP) and include dams equipped for power generation on the Green, Gunnison, Rio Grande, and Colorado rivers and on Deer and Plateau creeks in the states of Wyoming, Utah, Colorado, Arizona, and New Mexico. Of these facilities, only the Glen Canyon Unit, the Flaming Gorge Unit, and the Aspinall Unit (which includes Blue Mesa, Morrow Point, and Crystal dams;) are influenced by Western power scheduling and transmission decisions. The EIS alternatives, called commitment-level alternatives, reflect combinations of capacity and energy that would feasibly and reasonably fulfill Westerns firm power marketing responsibilities, needs, and statutory obligations. The viability of these alternatives relates directly to the combination of generation capability of the SLCA/IP with energy purchases and interchange. The economic and natural resource assessments in this environmental impact statement (EIS) include an analysis of commitment-level alternatives. Impacts of the no-action alternative are also assessed. Supply options, which include combinations of electrical power purchases and hydropower operational scenarios reflecting different operations of the dams, are also assessed. The EIS evaluates the impacts of these scenarios relative to socioeconomics, air resources, water resources, ecological resources, cultural resources, land use, recreation, and visual resources.

    Clostridium difficile-associated diarrhea is a well-recognized complication of antibiotic use. Historically, diagnosing C. difficile has been difficult, as antigen assays are insensitive and culture-based methods require several days to yield results. Nucleic acid amplification tests (NAATs) are quickly becoming the standard of care. We compared the performance of two automated investigational/research use only (IUO/RUO) NAATs for the detection of C. difficile toxin genes, the IMDx C. diffici...

    International Nuclear Information System (INIS)

    The Colorado River Storage Project Customer Office of the Western Area Power Administration (Western) markets electricity produced at hydroelectric facilities operated by the Bureau of Reclamation. The facilities are known collectively as the Salt Lake City Area Integrated Projects (SLCA/IP) and include dams equipped for power generation on the Colorado, Green, Gunnison, and Rio Grande rivers and on Plateau Creek in Arizona, Colorado, Utah, Wyoming, and New Mexico. Of these facilities, only the Glen Canyon Unit, the Flaming Gorge Unit, and the Aspinall Unit (which includes Blue Mesa, Morrow Point, and Crystal dams) are influenced by Western power scheduling and transmission decisions. The environmental impact statement (EIS) alternatives, called commitment-level alternatives, reflect combinations of capacity and energy that would feasibly and reasonably fulfill Western's firm power marketing responsibilities, needs, and statutory obligations. The viability of these alternatives relates directly to the combination of generation capability of the SLCA/IP with energy purchases and interchange. The economic and natural resource assessments in this EIS include an analysis of commitment-level alternatives. Impacts of the no-action alternative are also assessed. Supply options, which include combinations of electrical power purchases and hydropower operational scenarios reflecting different operations of the dams, are also assessed. The EIS evaluates the impacts of these scenarios relative to socioeconomics, air resources, water resources, ecological resources, cultural resources, land use, recreation, and visual resources. Western has identified commitment-level alternative 1, the Post-1989 commitment level, as its preferred alternative. The impact evaluations indicate that this commitment level is also the environmentally preferred alter native

    The book presents in-depth material covering the full scope of tasks and problems of differential diagnostic radiology in children. The particular approach chosen by the authors provides information that will solve even the most difficult cases, guiding the reader on his way from radiographic findings to appropriate diagnosis. All radiographic findings have been characterized and classified and put into a tabulated system relating them to the relevant differential diagnosis. The system of reference adopted specifies a given lesion or disease by reference to the most significant diagnostic keywords obtained from anamnesis, clinical data, and further diagnostic evaluation. The tentative diagnosis is taken as the basis for further specification illustrated by the characteristic X-ray pictures and full-text descriptions. Almost all diagnoses are accompanied by a comprehensive image documentation obtained by all currently available imaging methods. (MG) [Deutsch] Das vorliegende Buch gibt einen kompletten Ueberblick ueeber die gesamte Bandbreite der Differentialdiagnostik in der Paediatrischen Radiologie und soll so auch in schwierigen Faeellen den Weg vom Roentgensymptom zur Diagnose ermoeglichen.

    Full Text Available This article provides a new critical edition and a commentary of Peire Bremon Ricas Novas’s “Rics pres, ferms e sobeirans”, a courtly love song composed between 1228 and 1257 and dedicated to Audiart del Baux. Built as a eulogy of the lady, the song focuses on the central theme of the moral and material ‘ricor’ (richness of the latter. The complexity of the metrical form, which displays a systematic use of the technique of ‘rim derivatiu’, is paralleled by the semantic obscurity of a number of verses and hapaxes, all discussed in the commentary. Stanzas III and IV show echoes of Jaufre Rudel’s “amor de lonh”, since the lover-poet declares that the distance and the ethnical difference between himself and the lady are abolished by the strength of his feelings. The use of ethnonyms in stanza IV is closely examined: the lover-poet reveals that he loves a Castilian lady who looks like a ‘Serrana’ (the name of an Iberian population, admitting that he would like her even if she were Catalan or Syrian. These references to the lady’s ethnical origins are puzzling: they can be read as a calembour with burlesque overtones, as well as a climax aiming to define the real provenance of the lady or as a rhetorical device to underline that courtly love does not know any kind of boundary.

    Full Text Available This paper provides a new critical edition of “Se·l mals d’amor m’auzi ni m’es noisens” by Blacasset and “Dieus es amors e verais salvamens by Pujol”. These two poets discuss a topic that is entirely new to Occitan lyric poetry: two young women about to enter a convent. While Blacasset expresses sadness about their choice of life in a convent, using elements of the funeral lament, Pujol praises it and believes it to be the only remedy for the corruption of the world. The tenso between women “Na Carenza al bel cors avenenç” seems to be conceived as a parody of this lyric debate: in the dialogue Alaisina and Yselda, who have doubts about becoming mothers, ask Na Carenza whether it is better to stay virgins or to marry; the latter advises them, in cryptic terms that are difficult to interpret, to become nuns, thereby gaining a husband (God but not children. I will suggest that the question of female authorship for this text be reconsidered, while proposing a new interpretation in the light of the lively debate in the medieval period about the suitability and prerogatives of virginity.

    The aim of the environmental epidemiologic study was to determine possible negative effects on the health of children in the very polluted areas of Bitterfeld and Hettstedt in comparison to the less polluted areas of Anhalt-Zerbst (Eastern Germany). The time changes of the health parameters were recorded along with the running redevelopments during the time period of 6 years. The study design consisted of three repeated regional cross sectional studies in 1992/93, 1995/96 and 1998/99. In all, there was information of 7.611 questionnaires to be analysed (participation rate: 89%, 75% and 75%). Children living in the most polluted area of Hettstedt had a noticeable higher risk for non allergic respiratory diseases and symptoms compared to children living in the control area of Anhalt-Zerbst. During the time of the examinations in 1992 till 1999 a clear statistically significant decrease in the prevalences of these restrictions of health could be shown. Children without indoor pollutants in their homes profited most by the improvement of ambient air quality. The better lung function (FVC, FEV{sub 1}) between 1992 and 1999 underlines the improvement of the respiratory health. Children living in both polluted ares have allergies more often (physician's diagnosis, symptoms, allergy specific antibodies). The incidence of asthma, the bronchial hyperreactivity and atopic exzema increased, the prevalence of rhinitis and allergic sensitization did not increase. The body burden with lead and cadmium was higher in children living in polluted areas, but it decreased during the period of observation. In 1997, however, the lead concentration in blood increased a little, parallel to the higher lead concentration in settled dust in Hettstedt at that time. (orig.) [German] Ziel der umweltepidemiologischen Studie war es, moegliche gesundheitliche Beeitraechtigungen von Kindern in den Belastungsgebieten Bitterfeld und Hettstedt i. Vgl. zu dem wenig belasteten Gebiet Anhalt-Zerbst zu ermitteln. Darueber hinaus wurden die zeitlichen Veraenderungen der Gesundheitsparameter begleitend zu den laufenden Sanierungsmassnahmen ueber den Zeitraum von 6 Jahren erfasst. Das Studiendesign bestand aus 3 wiederholten regionalen Querschnittsuntersuchungen in den Jahren 1992/93, 1995/96 und 1998/99. Insgesamt lagen Informationen von 7611 Frageboegen zur Auswertung vor (Beteiligungsrate: 89%, 75% bzw. 75%). Fuer die Belastungsregion Hettstedt waren deutlich hoehere Risiken fuer nicht allergische respiratorische Erkrankungen und Symptome im Vergleich zu Kindern des Kontrollgebietes Anhalt-Zerbst nachweisbar. Waehrend des Untersuchungszeitraumes 1992-1999 zeigte sich eine deutlich statistisch signifikante Abnahme der Praevalenz dieser gesundheitlichen Einschraenkungen, Kinder ohne Exposition mit Innenraumschadstoffen im haeuslichen Bereich profitieren von der Verbesserung der Aussenluftbelastung am meisten. Fuer die Verbesserung der Atemwegsgesundheit sprachen auch bessere Lungenfunktionswerte (FVC, FEV{sub 1}) im Laufe des Beobachtungszeitraumes 1992-1999. Kinder aus den beiden Belastungsregionen hatten haeufiger Allergien (Arztdiagnose, Symptome, allergenspezifischer Antikoerper-Nachweis). Die Haeufigkeit des Asthmas, der bronchialen Hyperreaktivitaet und der Neurodermitis nahm zu; die Praevalenz des Heuschnupfens und der allergischen Sensibilisierung nicht. Die korporale Belastung mit Blei und Cadmium war bei Kindern in den belasteten Regionen erhoeht, nahm aber im Verlauf des Beobachtungszeitraumes ab. Allerdings folgten gestiegenen Bleigehalten im Sedimentationsstaub in Hettstedt im Jahre 1997 leicht gestiegene Blutbleikonzentrationen. (orig.)

    2013-01-01

    Full Text Available The lack of studies on the more traditional love songs composed by Raimbaut de Vaqueiras, compared with the great success of his more experimental poems amongst scholars, has been repeatedly stigmatized. This paper offers a global and detailed reading of a ‘canso’ which is emblematic in the troubadour’s poetry. The vocabulary and stylistic features have been analyzed comparatively in order to correct an erroneous interpretation based on the story told by the ‘razo’ and to recognize the poem’s importance within Raimbaut’s production. This poem, no less than others by the same poet, reveals the most significant marks of its author’s poetic spirit: his curiosity towards reality and his receptiveness. A new critical edition of the text is provided here, based on the revision and a more extensive study of the manuscript tradition.

    La semilla es el órgano que garantiza la propagación y continuidad evolutiva de las plantas espermatofitas y constituye un elemento indispensable en la alimentación humana y animal. La semilla de cereales acumula en el endospermo durante la maduración, mayoritariamente, almidón y proteínas de reserva. Estas reservas son hidrolizadas en la germinación por hidrolasas sintetizadas en la aleurona en respuesta a giberelinas (GA), siendo la principal fuente de energía hasta que la plántula emergent...

    Three new prenylated flavonoids, namely, solophenols B (1), C (2), and D (3), as well as a new prenylated stilbene, solomonin (4), were isolated from propolis collected from the Solomon Islands. In addition, 17 known compounds were identified. The structures of the new compounds were determined by a combination of methods, including mass spectrometry and NMR. These new compounds and several known compounds were tested for antibacterial activity against Staphylococcus aureus, Bacillus subtilis, and Pseudomonas aeruginosa. Most of them exhibited potent antibacterial activity. These findings may indicate that propolis from the Solomon Islands has potential applications as an ingredient in food additives or pharmaceuticals. PMID:23067056

    The article provides a commentary and a new critical edition of an Occitan tenso between two Italian troubadours, Joan d’Albuzon and Nicolet de Turin. The tenso presents a dream and its interpretation: Joan claims to have dreamt of a terrifying eagle flying through the air, accompanied by a huge ship of fire sailing across the land from Cologne. Nicolet in turn interprets the dream in terms of an emperor sweeping through Lombardy with a great army of German soldiers at his command, paid from ...

    Full Text Available The article provides a commentary and a new critical edition of an Occitan tenso between two Italian troubadours, Joan d’Albuzon and Nicolet de Turin. The tenso presents a dream and its interpretation: Joan claims to have dreamt of a terrifying eagle flying through the air, accompanied by a huge ship of fire sailing across the land from Cologne. Nicolet in turn interprets the dream in terms of an emperor sweeping through Lombardy with a great army of German soldiers at his command, paid from his vast supply of treasure. Joan’s dream concludes with a vision of the eagle blowing out the fire, shining a great light over Montferrat, and settling in a high eyrie from which the whole world, now joyful, can be surveyed. Nicolet expounds this as the emperor’s desire for peace after vengeance, the Marquis of Montferrat’s submission, the emperor’s position of supreme command, and the prospect of appropriate rewards. The emperor is Frederick II Hohenstaufen and the author of the article proposes a new dating of the poem: it was probably composed in 1238 when the emperor, after his victory at the battle of Cortenuova in 1237 and subsequent subjection of several cities of the rebellious Lombard League, was arriving in Turin to receive the homage of Boniface II of Montferrat.

    We evaluate the performance of the TBcID assay in a panel of 100 acid-fast bacilli cultures. Sixty-four isolates were TBcID positive for Mycobacterium tuberculosis complex (MTBC), whereas 36 gave negative results. These included 28 nontuberculous mycobacteria, one nonmycobacterial isolate, one M. tuberculosis, and six M. bovis BCG strains. This corresponds to a sensitivity of 90.14%, specificity of 100%, and positive and negative predictive values of 100% and 80.55%, respectively. The test is...

The test is rapid, easy to perform and interpret, and does not require sample preparation or instrumentation. However, a negative result does not exclude the presence of a strain belonging to MTBC, especially when mutations in mpb64 gene are present or some M. bovis BCG strains are isolated. The TBcID showed potential to assist in the identification of MTBC when the implementation and usage of molecular methods are often not possible, principally in resource-limited countries.

    The objective of the research project 'The world of renewable energies: Powerado' was to improve communication aimed at conveying renewable energies to children. In order to achieve his aim, materials for different age groups and multipliers have been developed. These helped determining successful strategies for communicating renewable energies. There were several reasons for the need of such a project. It may be the case that renewable energies have been included into the syllabus of primary schools, but they still have no prominent role at schools. Additionally, the training of multipliers for renewable energies shows severe deficits. The project consisted of ten interconnected modules which explicitly are described. Overall, the powerado project was a huge success. 58,000 estimated multipliers, children, adolescents and persons generally being interested in renewable energies have been reached by the project and its modules. So the powerado project achieved its main objective improving communication of renewable energies.

    The new sulfur recovery unit in SINOPEC Luoyang Company was designed to burn 0.5% 1.5% ammonia in sour gas. Due to the insufficient capacity of ammonia refining unit, 15% of ammonia in sour gas had to be burned for more than one year, thus balancing the ammonia gas produced by the new 11 t/h sour water stripper. The operation shows that the unit is reliable in design and has no plugging. The catalyst activity is normally maintained and sulfur quality and tail gas emission meet the specifications. Good operating experience has been accumulated.%中国石油化工股份有限公司洛阳分公司新建40 kt/a硫回收联合装置原设计酸性气中烧氨比例为0.5%~1.5%,因氨精制系统不匹配,进行了一年多的烧氨,烧氨比例达到15%,平衡了新建11t/h污水汽提装置产生的全部氨气.运行结果表明装置设计可靠,系统无堵塞,催化剂活性正常,硫黄质量正常,尾气排放达标,并积累了一定的生产操作经验.

    We present a study of B--> D0(CP)K- decays, where D0(CP) is reconstructed in non-CP (K-pi+), CP-even (K-K+,pi-pi+) and CP-odd (KS0 pi0) eigenstates, based on a sample of about 214 million Y(4S) -> BBbar decays collected with the BABAR detector at the PEP-II e+e- storage ring. We measure the ratios of branching fractions R+ = [Br(B- ->D0_CP+ K-)+Br(B+ ->D0_CP+ K+)]/[Br(B- ->D0 K-)] = 0.87 +/- 0.14(stat) +/- 0.06(syst), R- = [Br(B- ->D0_CP- K-)+Br(B+ ->D0_CP- K+)]/[Br(B- ->D0 K-)] = 0.80 +/- 0.14(stat) +/- 0.08(syst), and the CP asymmetries A_CP+ = 0.40 +/- 0.15 (stat) +/- 0.08 (syst) and A_CP- = 0.21 +/- 0.17 (stat) +/- 0.07 (syst) All results are preliminary.

    Full Text Available Abstract Background Rapid identification (ID and antibiotic susceptibility testing (AST of the causative micro-organism of bloodstream infections result in earlier targeting of antibiotic therapy. In order to obtain results of ID and AST up to 24 hours earlier, we evaluated the accuracy of direct inoculation of the Phoenix system from positive blood cultures (BACTEC by using Serum Separator Tubes to harvest bacteria from positive blood cultures. Results were compared to those of standard Phoenix procedure. Discrepancies between the two methods were resolved by using the API system, E-test or microbroth dilution. Results ID with the direct method was correct for 95.2% of all tested Enterobacteriaceae (n = 42 and 71.4% of Pseudomonas aeruginosa strains (n = 7. AST with the direct method showed a categorical agreement for Gram-negative rods (GNR of 99.0%, with 0.7% minor errors, 0.3% very major errors and no major errors. All antibiotics showed an agreement of >95%. The direct method for AST of Staphylococcus (n = 81 and Enterococcus (n = 3 species showed a categorical agreement of 95.4%, with a minor error rate of 1.1%, a major error rate of 3.1% and a very major error rate of 0.4%. All antibiotics showed an agreement of >90%, except for trimethoprim-sulfamethoxazole and erythromycin. Conclusions Inoculation of Phoenix panels directly from positive blood cultures can be used to report reliable results of AST of GNR a day earlier, as well as ID-results of Enterobacteriaceae. For Staphylococcus and Enterococcus species, results of AST can also be reported a day earlier for all antibiotics, except for erythromycin and trimethoprim-sulfamethoxazole.

    Evolved stars are crucial pieces to understand the dependency of the planet formation mechanism on the stellar mass and to explore deeper the mechanism involved in star-planet interactions. Over the past ten years, we have monitored about 1000 evolved stars for radial velocity variations in search for low-mass companions under the Penn State - Torun Centre for Astronomy Planet Search program with the Hobby-Eberly Telescope. Selected prospective candidates that required higher RV precision measurements have been followed with HARPS-N at the 3.6 m Telescopio Nazionale Galileo under the TAPAS project. We aim to detect planetary systems around evolved stars to be able to build sound statistics on the frequency and intrinsic nature of these systems, and to deliver in-depth studies of selected planetary systems with evidence of star-planet interaction processes. For HD 5583 we obtained 14 epochs of precise RV measurements collected over 2313 days with the Hobby-Eberly Telescope (HET), and 22 epochs of ultra-precise...

    We present new Spitzer IRS observations of HD164270 (WC9, WR103). A quantitative analysis of the UV, optical, near- and mid-IR spectrum of HD164270 is presented, allowing for line blanketing and wind clumping, revealing T* ~ 48kK, log L/L_sun ~ 4.9, dM/dt ~ 1e-5 M_sun/yr for a volume filling factor of f \\~ 0.1. Our models predict that He is partially recombined in the outer stellar wind, such that recent radio-derived mass-loss rates of WC9 stars have been underestimated. We obtain C/He ~ 0.2 and O/He ~ 0.01 by number from optical diagnostics. Mid-IR fine structure lines of [NeII] 12.8 and [SIII] 18.7micron are observed, with [NeIII] and [SIV] absent. From these we obtain Ne/He ~ Ne^+/He = 2.2e-3 by number, 7 times higher than the Solar value (as recently derived by Asplund et al.), and S/He ~ S^2+/He = 5.1e-5 by number. From a comparison with similar results for other WC subtypes we conclude that WC9 stars are as chemically advanced as earlier subtypes. We consider why late WC stars are exclusively observed ...

    The resistance of Escherichia coli to cephalothin was found to be overestimated when the Phoenix automated susceptibility system was used to determine resistance compared to reference broth microdilution, a finding that jeopardized the use of cephalexin for first-line treatment of urinary tract infections in children. In addition, using broth microdilution, we studied the accuracy of either cephalothin or cefazolin in predicting cephalexin susceptibility. In contrast to the recommendation of ...

    3D printing originally known as additive manufacturing is a process of making 3 dimensional solid objects from a CAD file. This ground breaking technology is widely used for industrial and biomedical purposes such as building objects, tools, body parts and cosmetics. An important benefit of 3D printing is the cost reduction and manufacturing flexibility; complex parts are built at the fraction of the price. However, layer by layer printing of complex shapes adds error due to the surface roughness. Any such error results in poor quality products with inaccurate dimensions. The main purpose of this research is to measure the amount of printing errors for parts with different geometric shapes and to analyze them for finding optimal printing settings to minimize the error. We use a Design of Experiments framework, and focus on studying parts with cone and ellipsoid shapes. We found that the orientation and the shape of geometric shapes have significant effect on the printing error. From our analysis, we also determined the optimal orientation that gives the least printing error.

    We present a measurement of R_B, the ratio of the branching fraction for the rare decay D0 -> K+ pi- to that for the Cabibbo-favored decay D0 -> K- pi+. Charge conjugate decays are implicitly included. A signal of 2005 +/- 104 events for the decay D0 -> K+ pi- is obtained using the CDF II detector at the Fermilab Tevatron collider. The data set corresponds to an integrated luminosity of 0.35 1/fb produced in p-bar/p collisions at sqrt{s}=1.96 TeV. Assuming no mixing, we find R_B = [ 4.05 +/- 0.21 (stat) +/- 0.11 (syst) ] x 10(-3). This measurement is consistent with the world average, and comparable in accuracy with the best measurements from other experiments.

    Full Text Available The only extant poem by Sail d’Escola, “Gran esfortz fai qui chanta ni·s deporta”, must have been quite successful with the troubadours since its melody was reused several times. Without a doubt its interest also lies in the fact that it mentions another (or others? poem in which the troubadour has recourse to the ‘mala canso’, believing, quite rightly, that he may offend the lady who proved to be a bad ‘amigua’. The text is ambiguous: it appears to be a love song asking for forgiveness to a lady who had previously been treated badly, but it also contains hidden threats of abuse, should the lady not show herself to be once more well-disposed towards her lover. This paper will propose a new interpretation of the simile in ll. 5-7, as well as some corrections to the previous edition (Chabaneau.

    Full Text Available This paper provides a critical edition, with a new hypothesis concerning two difficult loci, of “Quan lo fregz e·l glatz e la neus”, one of the most significant love songs by Giraut de Borneil. For l. 48 (according to the order of the stanzas in Kolsen’s edition which is confirmed here, I will argue that “gers”, present in nearly all the manuscripts and editions, but never explained satisfactorily and unique from the lexical viewpoint, is a ghost word. Thus I will suggest accepting the lesson of ms. B as a suitable, ancient conjecture: ‘of those who are inside (the beseiged castle and forced to surrender’ que an grans guerriers, ‘who have great enemies’. For l. 58 none of the solutions put forward so far are convincing, thus I will tentatively propose a new conjecture: the lover fears that his life will become plus breus... “que del quint dels quars”, ‘shorter that the fifth of the quarter (of the day’, that is, it will be cut off. This restores a rhetorical figure of repetition that marks the end of each stanza after the second and which has been lost in nearly all the manuscripts and editions. My reading of the text will underline its distinctive aspects: a large number of quite difficult similes, emphasis on the figure of the lover, a lack of the author intervention and of the sententiae and forms of argument that characterise this poet, a fast pace created by the syntactic and rhetorical structure. I will also examine all that may serve to place the text within a particular historical context, although despite the many hypotheses, the only sure element is that it was written for a courtly occasion in the presence of Richard the Lionheart.

    This preparatory study, ``Shaft barriers for underground waste repositories in abandoned salt mines``, was to demonstrate the current scientific and technological know-how based on a comprehensive analysis of the barrier design concepts or established structures intended to serve as barriers in abandoned shafts of potash or rock salt mines. Taking as a basis the current regulatory regime and the available know-how on barrier systems in underground waste repositories taken into account so far in plan approval and licensing procedures, as well as the state of the art, concepts are developed as technical guides and models of barrier systems for mine shafts. The required research work for the various components of a shaft barrier is shown, particularly relating to aspects such as materials suitability and technical realisation. Immediate demand for research activities is shown with regard to the available potentials of mathematic and numeric geotechnical and hydrogeologic calculation models required in order to give proof of the long-term workability of shaft barriers. The authors are of the opinion that the following activities are required in order to meet the research demand quantified: (1) Laboratory and bench-scale experiments for determination of the efficiency of various sealing materials and backfilling materials, and (2) an in-situ, large-scale experiment in order to demonstrate the suitability of low-consolidation shotter columns, or constructional technologies. The laboratory work can be done in the facilities of the GSF research mine of Asse, the Freiburg Mining Academy, and the Institut fuer Gebirgsmechanik in Leipzig, and the benchmark experiments also at the Asse site in the research mine. The Kali und Salz Beteiligungs AG is prepared to offer its mine Salzdetfurth II as a site for the large-scale experiment. (orig.)

Auf der Grundlage der vorhandenen gesetzlichen Regelwerke und des mit zu beruecksichtigenden Kenntnisstandes zu Verschlusssystemen fuer UTD in bisher durchgefuehrten Planfeststellungs- und Genehmigungsverfahren sowie des Standes von Wissenschaft und Technik wurden Konzepte fuer die technischen Loesungen von Verschlusssystemen fuer Schaechte entwickelt. Der sich daraus ableitende Forschungsbedarf zu den einzelnen Elementen eines Schachtverschlusses, insbesondere unter dem Aspekt der Materialauswahl und der technischen Realisierbarkeit, wird ausgewiesen. Im Hinblick auf den Nachweis der langzeitlichen Funktionsfaehigkeit von Schachtverschluessen werden die vorhandenen Moeglichkeiten mathematisch-numerischer geotechnischer und hydrogeologischer Berechnungsmodelle dargestellt. Dabei besteht ein unmittelbarer Forschungsbedarf. Die Verfasser sind der Auffassung, dass zur Abarbeitung des ermittelten Forschungsbedarfes 1. Labor - und Technikumsversuche zur Wirksamkeit verschiedener Dichtmaterialien und Widerlagerbaustoffe sowie 2. ein In-situ-Grossversuch zur Klaerung der Einsatzmoeglichkeiten setzungsarmer Schottersaeulen und Einbautechnologien der Verschlussbauwerke erforderlich sind.

    For more than two decades now experiences of ozone reduction have been made in the USA. In many regions great efforts for VOC control are made to reduce their high ozone concentrations in ambient air that in some cases reach up to more than twice the German peak concentrations. This report places focus on small stationary sources and products, for these sources actually contribute more than half of the VOC emissions in Germany and are still not regulated under the German Immission Control Law. Therefore, main aim of this examination was to determine the major elements of VOC control strategies in the U.S. and to consider, whether strategies and measures are transferable taking into account German circumstances. Volume 1 describes the strategies and measures for ozone control in the U.S. (national) as well as in five regions with high ozone concentrations in ambient air. The authorities and responsbilities at federal, state, regional, and local levels are highlighted, legislation and different types of regulations are explained, priorities concerning VOC versus NO{sub x} related control are mentioned and the control measures on different sources for reducing VOC and NO{sub x} are summarized briefly. Volume 2 contains a detailed description of control measures for reducing VOC emissions from products and stationary sources, namely the proposed national VOC emission standards for coatings and consumer products, the California Consumer Products Regulations, the state-wide requirements for industrial and commercial sources in California and the VOC related rules of the South Coast Air Quality Management District (LA and surrounded Countries). The South Coast Rules were chosen as an example for District Rules for they were generally the most stringent because of the extreme ozone concentration in this area. Moreover, the regulations for VOC emission control in Europe concerning small stationary sources and products are mentioned. The different approaches to control VOC emissions are compared and discussed. Advantages and disadvantages of the described strategies are highlighted. Based on the actual VOC emission inventory of Germany suggestions for future reduction measures are supposed. (orig.) [Deutsch] In den USA liegen Erfahrungen aus der Ozonbekaempfung ueber einen Zeitraum von 20 bis 30 Jahren vor. Aufgrund besonders hoher Ozonbelastungen in vielen Regionen werden grosse Anstrengungen zur VOC-Minderung unternommen. Wesentliches Ziel des Vorhabens war es, die Schwerpunkt im Hinblick auf die Minderung von VOC-Emissionen herauzufinden und zu pruefen, ob und inwieweit eine Uebertragung von Strategien und Massnahmen auf die Verhaeltnisse in Deutschland moeglich ist. Hauptaugenmerk wurde auf kleinere Anlagen und Produkte gelegt, weil in diesen Bereichen in Deutschland momentan vordringlich Handlungsbedarf gesehen wird. Im ersten Band sind die Strategien und Massnahmen zur Ozonminderung in den USA (bundesweit) sowie in fuenf Regionen mit besonders hoher Ozonimmissionsbelastung beschrieben. Hierzu erfolgte eine Darstellung der Zustaendigkeitsbereiche auf nationaler, einzelstaatlicher, regionaler und lokaler Ebene, der Gesetzgebung und Regelwerke, der Schwerpunktsetzung hinsichtlich NO{sub x}- und VOC-Minderung und eine kurze Darstellung der quellenbezogenen Massnahmen auf nationaler Ebene und in den betrachteten Regionen. In Band 2 erfolgt eine ausfuehrliche Beschreibung der Massnahmen zur VOC-Emissionsminderung bei Produkten und im gewerblichen Bereich in den USA anhand der nationalen Regelungen fuer Anstrichstoffe und Konsumgueter, der von der kalifornischen Luftreinhaltebehoerde erlassenen VOC-bezogenen Regelungen fuer Anstrichstoffe, Konsumgueter und Gewerbebetriebe sowie der Regelungen des suedkalifornischen South Coast Air Quality Management Districts (Los Angeles und Umgebung). Zur Darstellung der regionalen Bestimmung wurde diese Region ausgewaehlt, da die Regelungen dort aufgrund der besonders hohen Immissionsbelastung grundsaetzlich am weitesten gehen. Darueber hinaus werden die Regelungen zur VOC-Emissionsminderung fuer den Bereich der Kleinanlagen und Produkte in Europa dargestellt. Die unterschiedlichen Ansaetze zur VOC-Emissionsminderung werden zusammenfassend diskutiert, Vor-und Nachteile herausgearbeitet und unter Beruecksichtigung der derzeitigen VOC-Emissionssituation in Deutschland Ansatzpunkte fuer zukuenftige Massnahmenschwerpunkte aufgezeigt.

    Full Text Available Abstract Isolated blastomeres obtained by embryo biopsy serve mainly for preimplantation genetic screening. Blastomeres are undifferentiated embryonic cells that include all the embryo genetic information. A lot of developing technologies may benefit by the efficient cryopreservation of blastomeres for future potential use, especially for stem cell culture and differentiation control. We are hereby reporting for the first time the feasibility of preserving individual isolated blastomeres in microvolumes in a closed vitrification system. Using a cryotip and propagation in microvolumes, isolated mice blastomeres were vitrified and warmed with 100% post-warming survival.

    BACKGROUND: There is evidence that bipolar disorder (BD) is associated with significant neurocognitive deficits and this occurs in individuals with BD type I (BD I) and with BD type II (BD II). Only a few studies have focused on cognitive impairment in BD II. The aim of this study was to describe the pattern of cognitive impairment in patients with BD II, in order to identify specific cognitive deficits that distinguish BD II from BD I patients as well as from healthy subjects.

    @@ Are there great things to be discovered at the nanoscale? The answer is almost certainly"yes".From the microscale to the nanoscale,it is far from just scaling down,it is a "great leap forward"into a complete new regime where the physical and chemical properties of materials exhibit size dependent behaviour.A thorough understanding of the new physics and chemistry at the nanometer scale will lead to the design and fabrication of smart new functional materials and devices, for instance,electronic devices that operate on the basic principles of quantum mechanics.Nanofabrication will not go far without reliable measurement and characterisation methods.Indeed,the boom in nanotechnology all started when the scanning tunnelling microscopy (STM) was invented in 1982, which enabled surface imagning with atomic resolution.

    At present there are used various of procedures, calculation methods, models and model equations for hazardous incident scenarios. The procedure on principle is varying often. This guideline explains in one main part and six appendixes the methodical procedure to select specifications and assumptions on hazardous incident scenarios and their processing. Hazardous incident scenarios lead to information on emergency preparedness planning. Both general viewpoints and possibilities are shown, how to find necessary basic assumptions on a hazardous incident scenario from information on hazardous substances, on comparable hazardous incidents and on conditions of the site and the plant. Appendixes deal with precise instructions distinguished between substance release, explosion and fire (app. 1: Assessment of source terms, app. 2: Assessment of dispersion, app. 3: Assessment of effects). Appendix 4 gives explanations to appendixes 1, 2 and 3. Appendix 5 contains a collection of 15 examples of hazardous incident scenarios, which illustrate and comment the methodical procedure. Appendix 6 describes and comments software available on German market which assists the calculating of hazardous incidents. Volume 2 determines procedures with regard to methods of calculation, current models and model equations from scientists point of view. (orig.)

    At present there are used various procedures, calculation methods, models and model equations for hazardous incident scenarios. The procedure on principle is varying often. This guideline explains in one main part and six appendixes the methodical procedure to select specifications and assumptions on hazardous incident scenarios and their processing. Hazardous incident scenarios lead to information on emergency preparedness planning. Both general viewpoints and possibilities are shown, how to find necessary basic assumptions on a hazardous incident scenario from information on hazardous substances, on comparable hazardous incidents and on conditions of the site and the plant. Appendixes deal with precise instructions distinguished between substance release, explosion and fire (App. 1: Assessment of source terms, App. 2: Assessment of dispersion, App. 3: Assessment of effects). Appendix 4 gives explanations to appendixes 1, 2 and 3. Appendix 5 contains a collection of 15 examples of hazardous incident scenarios, which illustrate and comment the methodical procedure. Appendix 6 describes and comments software available on German market which assists the calculating of hazardous incidents. Volume 2 determines procedures with regard to methods of calculation, current models and model equations from scientists' point of view. (orig.)

    The Federal Ministry for Economics and Technology (BMWi) funds the '250 MW Wind' test programme. This programme is designed to acquire statistically relevant data concerning the practical use of wind energy converters (WEC) in the Federal Republic of Germany. The technological and scientific areas of this supportive measure, the so called 'Wissenschaftliches Mess- und Evaluierungsprogramm' (WMEP - Scientific Measurement and Evaluation Programme), are implemented by the Institut fuer Solar Energieversorgungstechnik (ISET - Institute for Solar Energy Supply Technology) in Kassel. The WMEP acquires performance data concerning all funded WECs for a ten year period. The final report on hand describes the results of the 3rd project phase (01/07/96 - 30/06/00) of the WMEP including four annual reports and a summary of the most important fields of work. In this phase, for the first time all evaluations could be based upon the complete plant stock since all funded projects were represented in the programme. As of 30/06/00, a total of 1,497 wind turbines with an installed capacity of 349.5 MW at approx. 1,100 different locations are under supervision. During the whole project phase a maximum of 1,557 turbines was supervised. The rated power of the turbines ranges from 2.5 kW up to 1.5 MW. Evaluations regarding the economy, the estimated lifetime and long-term reliability as well as the power performance of widely dispersed wind turbine systems could be initiated in this project phase. It should also be mentioned, that the WMEP evaluations do now include all wind turbines operated in Germany. (orig.) [German] Das Bundesministerium fuer Wirtschaft und Technologie (BMWi) foerdert mit dem Breitentest '250 MW Wind' die Einfuehrung der Windenergienutzung in Deutschland. Zur Gewinnung statistisch relevanter Erfahrungswerte aus dem praktischen Einsatz von Windenergieanlagen (WEA) wurde das Institut fuer Solare Energieversorgungstechnik e.V. (ISET), Kassel, mit der begleitenden Durchfuehrung des 'Wissenschaftlichen Mess- und Evaluierungsprogramms' (WMEP) beauftragt. Im Rahmen dieses Programms werden von allen gefoerderten WEA fuer einen Zeitraum von zehn Jahren ausgewaehlte Betriebsdaten und -ergebnisse erfasst und ausgewertet. Der vorliegende Abschlussbericht beschreibt die Ergebnisse der 3. Durchfuehrungsphase (01.07.1996 - 30.06.2000) des WMEP in vier Jahresberichten und einer Zusammenfassung der wichtigsten Arbeitsschwerpunkte. In der dritten Projektphase konnten erstmals Jahresauswertungen mit dem vollstaendigen Anlagenbestand druchgefuehrt werden, da alle bewilligten Projekte ins WMEP aufgenommen werden konnten. Zum 30.06.2000 betraegt der Anlagenbestand 1497 WEA mit einer installierten Nennleistung von insgesamt 349,5 MW, der an ca. 1.100 unterschiedlichen Standorten installiert ist. Insgesamt wurden im WMEP bis zu 1557 WEA messtechnisch begleitet. Das Leistungsspektrum der einzelnen WEA reicht dabei von 2,5 kW bis 1,5 MW. In der Projektphase III des WMEP standen besonders erste Auswertungen zur Wirtschaftlichkeit, zum Langzeitverhalten sowie zum Leistungsbeitrag der Windenergie im Vordergrund. Besonders hervorzuheben sind noch die ebenfalls in dieser Phase begonnenen Auswertungen zur zeitlichen Entwicklung der Windenergienutzung, die nunmehr alle in Deutschland betriebenen WEA umfassen.

    The expression of the cydDC operon was investigated by using a chromosomal phi(cydD-lacZ) transcriptional fusion and primer extension analysis. A single transcriptional start site was found for cydD located 68 bp upstream of the translational start site, and Northern blot analysis confirmed that cydDC is transcribed as a polycistronic message independently of the upstream gene trxB. cydDC was highly expressed under aerobic growth conditions and during anaerobic growth with alternative electron acceptors. Aerobic expression was independent of ArcA and Fnr, but induction of cydDC by nitrate and nitrite was dependent on NarL and Fnr. PMID:9335308

    Environmental considerations are becoming one of the key features in the design when it comes to constructing modern, sustainable residential buildings. In an effort to streamline procedures and practices, the project Longlife has conducted a comparative review of these among the countries Denmark, Germany, Lithuania, Poland and Russia (associated organizations). The countries involved have shared knowledge and experiences with each other about how their respective building processes operate. These are collated and analysed. There are differences and commonness in the state of technology, administrative and legal procedures, financial situation, demographic needs, and how a 'housing project' functions. With this exercise Longlife has started to ensure that differences across the Baltic Sea Region will be minimised as regards environmentally-friendly residential constructions. This initial comparative stage covers planning, building permit and tendering procedures, practices for developing and operating housing and construction technologies. The report reflects the currently most applicable features of the participating countries' processes. Longlife project partners work in three competence teams to use the special know how and experiences and to cooperate in the public private partnership composition. The report analyses in the competence team 1 - Engineering and building technology, design standards - the engineering and technology standards in the countries Denmark, Germany, Lithuania, Poland and Russia. The report shows for the competence team 2 - Administration procedures, licensing rules, tendering rules, laws - the comparison and investigations of administration procedures, building permit rules, tendering rules and laws in the participating countries. The report provides for competence team 3 - Economical and financial basis - a general and a specific overview about economical and financial issues, sustainability and quality aspects in the involved countries. This report is basis for the next work package: development of standards, criteria and specifications for a sustainable, resource saving residential building. (orig.)

    It is not easy for the consumer to select the right food. Supermarket displays, packaging or an attractive appearance may induce him to buy without reflecting. Food labels often present more problems than they propose to solve. Knowledge about food constituents is the best way to select food. Once the consumer knows what is inside food, and which of these substances are classified substances, it is easier for him to select the best food for his purposes and needs. The book therefore classifies fruit, vegetables, peas and beans potatoes and mushrooms, cereals, cakes and biscuits, sugar, chocolate, sweets, icecream, honey, marmalades, jellies and new foods according to their constituents. This includes nutrients (proteins, carbohydrates, fats, vitamins, minerals, roughage), additives (listed and unlisted), pollutants (natural, environmental and synthetic pollutants). The nature and function of the ingredients are explained in an introductory chapter. Agricultural and chemical production processes are discussed, and the range of products available on the market is listed alphabetically by groups of products or trade classes. Each chapter also contains information and practical household hints. [German] Aus der Fuelle des Lebensmittelangebots das Richtige auszuwaehlen, ist nicht leicht. Die Plazierung in den Regalen der Supermaerkte, die Verpackung oder das aeussere Erscheinungsbild verleiten den Verbraucher oft zu einem unueberlegten Einkauf. Auch die Kennzeichnung von Lebensmitteln gibt haeufig mehr Probleme auf, als dass sie Klarheit schafft. Am verlaesslichsten ist eine Beurteilung von Lebensmitteln anhand ihrer Inhaltsstoffe. Kennt sie der Verbraucher und weiss er, welche davon (nicht) kennzeichnungspflichtig sind, kann er sich leichter orientieren und besser nach seinen Beduerfnissen auswaehlen. In diesem Band werden deshalb Obst, Gemuese und Huelsenfruechte, Kartoffeln und Pilze, Getreide, Backwaren und Knabbererzeugnisse, Zucker, Schokolade, Zuckerwaren, Speiseeis, Honig, Konfituere, andere suesse Brotaufstriche und neuartige Lebensmittel nach ihren Inhaltsstoffen bewertet.

Our aim is to reflect on the ways to understand citizen participation in political and academic agenda, the role of different actors (citizens, professionals, politicians... and strategies and methods used in participatory urban planning. The experience showed in this paper is located in a scale of urban design very close and well known to the people. We begin with a brief historical overview of the neighborhood where the project arose. Then we give an account of the stages of the participatory process, showing the main milestones, features and methods. Finally we propose some ideas to rethink the conceptual and methodological aspects of the intervention and urban research in environmental psychology and people-environment studies.

    The occurrence of precious metals in the environment is increasing, due primarily to their use in catalytic converters for motor vehicles, and they were therefore integrated into the study programme in 1998. Urine samples of 1080 subjects were analysed for gold, platinum and iridium, resulting in mean concentrations of 46 ng/l, 2.2 ng/l and 0.2 ng/l. The number of dental inlays, crowns and bridge elements has a clear influence on the mean levels of gold and platinum in urine. Road traffic was not found to be a signficant factor. Nicotine and cotinine are common markers for exposure to tobacco smoke. Non-smokers exhibit a mean nicotine level in urine of less than 2 {mu}g/l and a cotinine level of less than 4 {mu}gl. Nicotine and cotinine levels in urine increase as a function of the number of cigarettes smoked per day, reaching values of 1080 {mu}g/l and 2060 {mu}g/l, respectively, when consumption exceeds 20 cigarettes per day. Exposure to environmental tobacco smoke is also reflected by nicotine and cotinine levels in urine. The present report provides representative data for environmentally related health monitoring and reporting at national level. The data serve as the basis for the formulation of reference values characterising the population's internal exposure to environmental contaminants. The report shows trends over time and regional differences in pollution, and identifies exposure pathways. The results of the Environmental Survey serve inter alia to achieve nationally harmonised methodologies for assessment, health-related environmental reporting, and the development and monitoring of prevention, intervention and abatement strategies within the scope of health and environmental policy actions.

    The aim of the project was to identify areas in households and the tertiary sector in which changes in behaviour could result in energy conservation and thus a reduction of greenhouse gas emissions, and to quantify the potentials for 1995, 2005 and 2020. A second focus was on the analysis and evaluation of programmes and instruments to realise the potentials. With literature evaluation, expert interviews, and a household servey potentials and further technical development have been identified. In sum, behavioural measures can contribute to the CO2 reduction by 64 million tons in 1995 in households and 27 in the commercial sector in which the potential decreases to 18 million tons in 2020 due to the autonomous technical development. Adequate promotion programmes can help to realise 20-30% of the potential by 2020. (orig.) [German] Ziel des Vorhabens war, im Sektor private Haushalte und Kleinverbrauch Bereiche zu identifizieren, in denen Verhaltensaenderungen zur Energieeinsparung fuehren koennen, und diese Potenziale fuer 1995, 2005 und 2020 zu quantifizieren. Darauf aufbauend waren Programme und Instrumente zur Umsetzung aufzuzeigen und zu bewerten. Gestuetzt auf Literaturrecherchen und Expertengespraeche wurden Einzelpotenziale, Rahmenbedingungen, Entwicklungstrends in der Technik und im Ausstattungsgrad ermittelt. Insgesamt koennten Verhaltensmassnahmen im Haushaltssektor die CO2-Emissionen im Basisjahr 1995 um 64 Mio, im Kleinverbrauch um 27 Mio t vermindern. Bis 2020 bleibt dieses Potenzial im Haushaltssektor in etwa gleich. Im Kleinverbrauch sinkt es infolge der autonomen Technikentwicklung auf 18 Mio t ab. Durch geeignete Programme koennen bis 2020 etwa 20-30% des Potenzials erreicht werden. (orig.)

    Full Text Available Der Band versammelt in internationaler Perspektive die sich teils diametral entgegenstehenden Positionen zur Sexarbeit im Allgemeinen sowie zur Frage der gewerkschaftlichen Interessenvertretung im Besonderen und lässt die Brisanz der Diskussion sowohl im feministischen als auch im arbeits(marktpolitischen Diskurs erkennen. Leider bleibt die Debatte in einem grundsätzlichen Für und Wider verhaftet und vernachlässigt die Diskussion und Evaluation konkreter Bemühungen gewerkschaftlicher Organisierungsstrategien in der Sexindustrie. Zu Wort kommen fast ausschließlich Vertreterinnen von Gewerkschaften oder Organisationen, die Sexarbeiter/-innen unterstützen. Nur zwei Beiträge stammen von Sexarbeiterinnen selbst.

    On behalf of the German Federal Environment Agency, this project was supposed to enhance the further development of an integrated sustainability policy in Germany. Focus of the project was the design of sustainable urban living environments, as everyday life related views of for example citizens, consumers, employees, traffic participants etc. can serve as a consistency check for an integrated sustainability policy. Political topics and stakeholders within the German environment department and beyond were analyzed in order to enhance an effective integrated sustainability policy and to identify potential synergies. For this as well as for the resolution of possible trade-offs a systematic and empirically based scenario process has been used. In the introductory empirical and planning phase the fundamentals were elaborated: Desk research, interviews and workshops were conducted to identify political topics and strategic fields, which then were checked for trade-offs and potential cooperations. For this first phase of the project stakeholders, as well as their motivations and underlying expectations for the future were identified. In the main phase of the project two complementary topics (''Recycling City'' and ''Sustainable Economy in the City'') were jointly selected and elaborated in two parallel conducted systematic and participatory scenario processes to generate integrated images of the future in 2030. Furthermore, options for action, strategic elements and potentials for networking were derived and concretized with regard to practical cooperation in the German Department of the Environment.

    Population declines and extinctions of amphibians have been attributed to the chytrid fungus Batrachochytrium dendrobatidis (Bd), especially one globally emerging recombinant lineage ('Bd-GPL'). We used PCR assays that target the ribosomal internal transcribed spacer region (ITS) of Bd to determine the prevalence and genetic diversity of Bd in South Korea, where Bd is widely distributed but is not known to cause morbidity or mortality in wild populations. We isolated Korean Bd strains from native amphibians with low infection loads and compared them to known worldwide Bd strains using 19 polymorphic SNP and microsatellite loci. Bd prevalence ranged between 12.5 and 48.0%, in 11 of 17 native Korean species, and 24.7% in the introduced bullfrog Lithobates catesbeianus. Based on ITS sequence variation, 47 of the 50 identified Korean haplotypes formed a group closely associated with a native Brazilian Bd lineage, separated from the Bd-GPL lineage. However, multilocus genotyping of three Korean Bd isolates revealed strong divergence from both Bd-GPL and the native Brazilian Bd lineages. Thus, the ITS region resolves genotypes that diverge from Bd-GPL but otherwise generates ambiguous phylogenies. Our results point to the presence of highly diversified endemic strains of Bd across Asian amphibian species. The rarity of Bd-GPL-associated haplotypes suggests that either this lineage was introduced into Korea only recently or Bd-GPL has been outcompeted by native Bd strains. Our results highlight the need to consider possible complex interactions among native Bd lineages, Bd-GPL and their associated amphibian hosts when assessing the spread and impact of Bd-GPL on worldwide amphibian populations.
