    Infrared spectra of the matrix isolated OMS, OM(η(2)-SO), and OM(η(2)-SO)(η(2)-SO(2)) (M = Ti, Zr, Hf) molecules were observed following laser-ablated metal atom reactions with SO(2) during condensation in solid argon and neon. The assignments for the major vibrational modes were confirmed by appropriate S(18)O(2) and (34)SO(2) isotopic shifts, and density functional vibrational frequency calculations (B3LYP and BPW91). Bonding in the initial OM(η(2)-SO) reaction products and in the OM(η(2)-SO)(η(2)-SO(2)) adduct molecules with unusual chiral structures is discussed.

    Porous manganese oxide (OMS-2) and platinum supported on OMS-2 catalysts have been shown to facilitate the hydrogenation of the nitro group in chloronitrobenzene to give chloroaniline with no dehalogenation. Complete conversion was obtained within 2 h at 25 °C and, although the rate of reaction increased with increasing temperature up to 100 °C, the selectivity to chloroaniline remained at 99.0%. Use of Pd/OMS-2 or Pt/Al2O3 resulted in significant dechlorination even at 25 °C and 2 bar hydrogen pressure giving a selectivity to chloroaniline of 34.5% and 77.8%, respectively, at complete conversion. This demonstrates the potential of using platinum group metal free catalysts for the selective hydrogenation of halogenated aromatics. Two pathways were observed for the analogous nitrobenzene hydrogenation depending on the catalyst used. The hydrogenation of nitrobenzene was found to follow a direct pathway to aniline and nitrosobenzene over Pd/OMS-2 in contrast to the OMS and Pt/OMS-2 catalysts which resulted in formation of nitrosobenzene, azoxybenzene and azobenzene/hydrazobenzene intermediates before complete conversion to aniline. These results indicate that for Pt/OMS-2 the hydrogenation proceeds predominantly over the support with the metal acting to dissociate hydrogen. In the case of Pd/OMS-2 both the hydrogenation and hydrogen adsorption occur on the metal sites.

  3. Overtone Mobility Spectrometry: Part 4. OMS-OMS Analyses of Complex Mixtures

    A new, two-dimensional overtone mobility spectrometry (OMS-OMS) instrument is described for the analysis of complex peptide mixtures. OMS separations are based on the differences in mobilities of ions in the gas phase. The method utilizes multiple drift regions with modulated drift fields such that only ions with appropriate mobilities are transmitted to the detector. Here we describe a hybrid OMS-OMS combination that utilizes two independently operated OMS regions that are separated by an ion activation region. Mobility-selected ions from the first OMS region are exposed to energizing collisions and may undergo structural transitions before entering the second OMS region. This method generates additional peak capacity and allows for higher selectivity compared with the one-dimensional OMS method. We demonstrate the approach using a three-protein tryptic digest spiked with the peptide Substance P. The [M + 3H]3+ ion from Substance P can be completely isolated from other components in this complex mixture prior to introduction into the mass spectrometer.

    Sodium octahedral molecular sieve nanorods (Na-OMS-2) were prepared through a facile hydrothermal method. The effects of reaction temperature and duration on particle sizes of the products were investigated. The electrochemical performance of samples was studied by constant current charge–discharge tests as cathode material for Li-ion batteries (LIBs). The initial discharge capacity of Na-OMS-2 is 123.4 mAh g−1 and the capacity retention was 123.9 mAh g−1 after 100 cycles. The result demonstrates that Na-OMS-2 cathode material behaves a good cycling stability.

    2012-01-01

    This paper presents the results of an assessment of the Polish occupational medicine service (OMS) system made by OMS nurses. The survey was carried out on a random group of OMS nurses. OMS nurses form a professional group comprised of rather experienced personnel. In the opinion of almost 70% of respondents the system guarantees good occupational heath care, whereas 20% took the opposite view. The great majority of respondents think that all employees have to undergo mandatory prophylactic examinations. The nurses have rather critical opinion about the legal regulations pertaining to occupational health care--their number and complexity, and also express negative opinion about the quality of cooperation with employers (who are contractors for OMS units). OMS nurses believe that prophylactic examinations are the strongest point of the system. They are often the only opportunity for establishing contact between an employee and a physician and learning about diseases he or she was previously unaware of. Although the general assessment of the OMS system is rather positive, it is not free of shortcomings. Improvements in such fields as legislation, financing of service, professional attitude towards responsibilities of the OMS staff, cooperation with employers (contractors) and primary health care units would undoubtedly result in even better assessment, and what is more important in better functioning of the Polish OMS system.

    RéSUMé: OBJECTIF : Déterminer les taux d'accord et la reproductibilité intra et inter-observateurs des classifications OMS 1973 et OMS 2004 des tumeurs urothéliales papillaires de la vessie. MATéRIEL ET MéTHODES : Cent deux cas de tumeurs urothéliales papillaires de stade pTa/pT1 ont été étudiés. Deux pathologistes ont revu les lames et ont établi le grade tumoral selon les deux classifications OMS 1973 et OMS 2004. En cas de désaccord, les deux évaluateurs ont procédé à une lecture commune au microscope en double tête afin d'aboutir à un grade consensuel selon les deux classifications. La variabilité intra-observateur a été étudiée chez l'un des deux évaluateurs qui a procédé à la relecture des lames un mois après sa première lecture. Les taux d'accord entre les deux pathologistes pour chaque catégorie de grade ont été déterminés et la reproductibilité des deux classifications a été évaluée à l'aide du coefficient kappa. Une valeur de 0 à 0,2 était interprétée comme un désaccord absolu, de 0,21 à 0,4, un accord faible, de 0,41 à 0,6, un accord modéré, de 0,61 à 0,8, un accord considérable, et de 0,8 à 1, un accord absolu. RéSULTATS : Selon la classification OMS 1973, les proportions des grades G1, G2 et G3 étaient respectivement de 40,2 %, 50 % et 9,8 %. Selon la classification OMS 2004, les proportions respectives des tumeurs de faible potentiel de malignité, des carcinomes de bas grade et des carcinomes de haut grade de malignité étaient de 23,5 %, 60,8 % et 15,7 %. La reproductibilité intra-observateur était excellente pour les deux classifications (accord absolu). Les taux d'accord entre les deux pathologistes étaient meilleurs pour la classification OMS 2004 (kappa = 0,7) que pour la classification OMS 1973 (kappa = 0,51). La reproductibilité entre observateurs de la classification OMS 2004 est supérieure à celle de 1973. La reproductibilité intra-observateur est excellente pour les deux

    The Space Station Freedom Program (SSFP) Operations Management System (OMS) will automate major management functions which coordinate the operations of onboard systems, elements and payloads. The objectives of OMS are to improve safety, reliability and productivity while reducing maintenance and operations cost. This will be accomplished by using advanced automation techniques to automate much of the activity currently performed by the flight crew and ground personnel. OMS requirements have been organized into five task groups: (1) Planning, Execution and Replanning; (2) Data Gathering, Preprocessing and Storage; (3) Testing and Training; (4) Resource Management; and (5) Caution and Warning and Fault Management for onboard subsystems. The scope of this prototyping effort falls within the Fault Management requirements group. The prototyping will be performed in two phases. Phase 1 is the development of an onboard communications network fault detection, isolation, and reconfiguration (FDIR) system. Phase 2 will incorporate global FDIR for onboard systems. Research into the applicability of expert systems, object-oriented programming, fuzzy sets, neural networks and other advanced techniques will be conducted. The goals and technical approach for this new SSFP research project are discussed here.

    Cryptomelane type manganese dioxides (α-MnO2, OMS-2) are interesting potential cathode materials due to the ability of their one dimensional (1D) tunnels to reversibly host various cations including Li+and an accessible stable 3+/4+ redox couple. Here, we synthesized metal cation free OMS-2 materials where the tunnels were occupied by only water and hydronium ions. Water was subsequently removed from the tunnels. Cation free OMS-2 and Dry-OMS-2 were used as cathodes in Li based batteries to investigate the role of tunnel water on their electrochemistry. The initial discharge capacity was higher for Dry-OMS-2 (252 mAh/g) compared to OMS-2 (194 mAh/g), however, after 100 cycles Dry-OMS-2 and OMS-2 delivered 137 mAh/g and 134 mAh/g, respectively. Li+ion diffusion was more facile for Dry-OMS as evidenced by rate capability, at 400 mA/g. Dry-OMS-2 delivered 135mAh/g whereas OMS-2 delivered ~115 mAh/g. This first report of the impact of tunnel water on the electrochemistry of OMS-2 type materials demonstrates that the presence of tunnel water in OMS-2 type materials negatively impacts the electrochemistry.

  19. The effect of Ce ion substituted OMS-2 nanostructure in catalytic activity for benzene oxidation

    2014-11-01

    The nanostructure of Ce doped OMS-2 plays a very important role in its catalytic property. We demonstrate by density functional theory (DFT) calculations that the unique nanostructure of the Ce ion substituted OMS-2 with Mn vacancy in the framework is beneficial for the improvement of catalytic activity, while the nanostructure of the Ce ion substituted OMS-2 without defects are detrimental to the catalytic activity. We establish a novel and facile strategy of synthesizing these unique Ce ion substituted OMS-2 nanostructure with Mn vacancies in the framework by hydrothermal redox reaction between Ce(NO3)3 and KMnO4 with KMnO4/Ce(NO3)3 at a molar ratio of 3 : 1 at 120 °C. Compared to pure OMS-2, the produced catalyst of Ce ion substituted OMS-2 ultrathin nanorods exhibits an enormous enhancement in the catalytic activity for benzene oxidation, which is evidenced by a significant decrease (ΔT50 = 100 °C, ΔT90 = 129 °C) in the reaction temperature of T50 and T90 (corresponding to the benzene conversion = 50% and 90%), which is considerably more efficient than the expensive supported noble metal catalyst (Pt/Al2O3). We combine both theoretical and experimental evidence to provide a new physical insight into the significant effect due to the defects induced by the Ce ion substitution on the catalytic activity of OMS-2. The formation of unique Ce ion substituted OMS-2 nanostructure with Mn vacancies in the framework leads to a significant enhancement of the lattice oxygen activity, thus tremendously increasing the catalytic activity.The nanostructure of Ce doped OMS-2 plays a very important role in its catalytic property.

    2011-01-01

    Solid-phase photocatalytic degradation of polyethylene (PE) film with cryptomelane-type manganese oxide (OMS-2) as photocatalyst was investigated in the ambient air under ultraviolet and visible light irradiation. The properties of the composite films were compared with those of the pure PE film through performing weight loss monitoring, IR spectroscopy, scanning electron microscopic (SEM) and X-ray photoelectron spectroscopy (XPS). The photoinduced degradation of PE-OMS-2 composite films was higher than that of the pure films, while there has been little change under the visible light irradiation. The weight loss of PE-OMS-2 (1.0 wt%) composite films steadily decreased and reached 16.5% in 288 h under UV light irradiation. Through SEM observation there were some cavities on the surface of composite films, but few change except some surface chalking phenomenon occurred in pure PE film. The degradation rate with ultraviolet irradiation is controllable by adjusting the content of OMS-2 particles in PE plastic. Finally, the mechanism of photocatalytic degradation of the composite films was briefly discussed.

    1994-01-01

    The Pump and Valve Inservice Testing (IST) Program Sat San Onofre, Units 2 and 3, was updated for the second 120-month interval from August 1993 to April 1994. The U.S. Nuclear Regulatory Commission (USNRC) approved the OM-6 and OM-10 Codes in mid-1992. The project for the rollover to these new Codes included several elements: (a) a review of the differences between IWV/IWP and OM-6/OM-10, (b) a comprehensive audit of the IST Program scope for valves, (c) creation of the program and supporting basis documents, the Relief Requests, and implementing procedures, (d) interdivisional coordination, (e) submittal to the USNRC, and (f) training. Subsections IWV and IWP have been used and essentially unchanged for over a decade. The new Code (Parts 1, 6, and 10 called OM-1, OM-6, and OM-10) includes several significant changes from the old Code. Our group identified these differences and drafted revised and reorganized Inservice Testing (IST) Program documents. We also considered USNRC Generic Letter 89-04 (GL 89-04), open-quotes Guidance on Developing Acceptable Inservice Testing Programsclose quotes, and NUREG-1482, Guidelines for Inservice Testing at Nuclear Power Plants, while revising the program. There were six pump relief requires and 13 valve relief requests in the program for the first 10-year interval. For the revised program we needed only one pump relief request (and no valve relief requests). Converting to the 1989 edition of the ASME Code did not require changes to the technical specifications. We revised our Updated Final Safety Analysis Report (UFSAR) to reflect the IST Program for the second 10-year interval. UFSAR changes were minor, consisting of updated references to the Code edition and 10 CFR 50.55a(f), open-quotes Inservice Testing Requirementsclose quotes

  7. Remarkable promotion effect of trace sulfation on OMS-2 nanorod catalysts for the catalytic combustion of ethanol.

    Science.gov (United States)

    Zhang, Jie; Zhang, Changbin; He, Hong

    2015-09-01

    OMS-2 nanorod catalysts were synthesized by a hydrothermal redox reaction method using MnSO4 (OMS-2-SO4) and Mn(CH3COO)2 (OMS-2-AC) as precursors. SO4(2-)-doped OMS-2-AC catalysts with different SO4(2-) concentrations were prepared next by adding (NH4)2SO4 solution into OMS-2-AC samples to investigate the effect of the anion SO4(2-) on the OMS-2-AC catalyst. All catalysts were then tested for the catalytic oxidation of ethanol. The OMS-2-SO4 catalyst synthesized demonstrated much better activity than OMS-2-AC. The SO4(2-) doping greatly influenced the activity of the OMS-2-AC catalyst, with a dramatic promotion of activity for suitable concentration of SO4(2-) (SO4/catalyst=0.5% W/W). The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma optical emission spectroscopy (ICP-OES), NH3-TPD and H2-TPR techniques. The results showed that the presence of a suitable amount of SO4(2-) species in the OMS-2-AC catalyst could decrease the Mn-O bond strength and also enhance the lattice oxygen and acid site concentrations, which then effectively promoted the catalytic activity of OMS-2-AC toward ethanol oxidation. Thus it was confirmed that the better catalytic performance of OMS-2-SO4 compared to OMS-2-AC is due to the presence of some residual SO4(2-) species in OMS-2-SO4 samples. Copyright © 2015.

    Low valent manganese species and surface oxygen vacancies in OMS-2 play an important role in catalytic reactions, and it is highly desirable and challenging to develop a feasible strategy of increasing the Mn(II) and Mn(III) species concentration in the oxide. Herein, the OMS-2/g-C3N4 hybrids (OMS-2/CN) were prepared by a facile refluxing approach. It was found that the MnOx precursor from the reaction of KMnO4 and MnSO4 was transformed into OMS-2 nanofibers with the formation of more Mn(II) and Mn(III) species in OMS-2 and the destruction and oxidation of g-C3N4. The hybrids exhibited higher efficiency for pollutants degradation in the presence of PMS than the pure OMS-2 or g-C3N4. There was a linear correlation between the specific initial rate and the ratio of Mn(II + III)/Mn(IV). Mechanism investigation indicated that high active manganese species or caged radicals were produced through the oxidation of Mn(II) and Mn(III) by PMS and contributed to the degradation reaction. During five consecutive cycles, the catalyst exhibited good reusability and stability. Therefore, the OMS-2/CN hybrids are promising catalysts for wastewater treatment with PMS as the oxidant.

    Brown, Steven G; Lee, Taehyoung; Roberts, Paul T; Collett, Jeffrey L

    2013-12-01

    Understanding the organic matter/organic carbon (OM/OC) ratio in ambient particulate matter (PM) is critical to achieve mass closure in routine PM measurements, to assess the sources of and the degree of chemical processing organic aerosol particles have undergone, and to relate ambient pollutant concentrations to health effects. Of particular interest is how the OM/OC ratio varies in the urban environment, where strong spatial and temporal gradients in source emissions are common. We provide results of near-roadway high-time-resolution PM1 OM concentration and OM/OC ratio observations during January 2008 at Fyfe Elementary School in Las Vegas, NV, 18 m from the U.S. 95 freeway soundwall, measured with an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-AMS). The average OM/OC ratio was 1.54 (+/- 0.20 standard deviation), typical of environments with a low amount of secondary aerosol formation. The 2-min average OM/OC ratios varied between 1.17 and 2.67, and daily average OM/OC ratios varied between 1.44 and 1.73. The ratios were highest during periods of low OM concentrations and generally low during periods of high OM concentrations. OM/OC ratios were low (1.52 +/- 0.14, on average) during the morning rush hour (average OM = 2.4 microg/m3), when vehicular emissions dominate this near-road measurement site. The ratios were slightly lower (1.46 +/- 0.10) in the evening (average OM = 6.3 microg/m3), when a combination of vehicular and fresh residential biomass burning emissions was typically present during times with temperature inversions. The hourly averaged OM/OC ratio peaked at 1.66 at midday. OM concentrations were similar regardless of whether the monitoring site was downwind or upwind of the adjacent freeway throughout the day, though they were higher during stagnant conditions (wind speed < 0.5 m/sec). The OM/OC ratio generally varied more with time of day than with wind direction and speed.

    To test for hypothesized disease- and treatment-induced changes in cytokines and adhesion molecules in children with opsoclonus-myoclonus syndrome (OMS). Multiplex bead assay technology was used for simultaneous measurement of 34 soluble cytokines in cerebrospinal fluid (CSF) and serum. Soluble intercellular adhesion molecule-1 (sICAM-1) and vascular cell adhesion molecule-1 (sVCAM-1) were measured by ELISA. In total, there were 388 children (239 OMS, 114 controls, and 35 other inflammatory neurological disorders (OIND)). In untreated OMS, mean CSF IL-6 was elevated 2.3-fold, but 67-fold in OIND, without significant differences in other CSF cytokines. Mean serum concentrations of sIL-2Ra (+50%) and CXCL1 (+70%) (pOMS than controls (p=0.005), as was serum CCL11 and IL-13 in treated OMS. Mean CSF CCL4 and IL-1Ra were selectively higher in IVIg-treated OMS (p≤0.0001). CSF sICAM-1 was elevated only in OIND (3.3-fold); serum sICAM-1 was higher in untreated OMS (+21%); and sVCAM-1 was not affected. No correlations with OMS severity or duration were identified. Novel cytokine, cytokine antagonist, and soluble adhesion molecule abnormalities due to OMS or treatment were found. However, the normality of much of the data strengthens previous findings implicating B cell mechanisms. Copyright © 2013 Elsevier B.V. All rights reserved.

  3. Enhanced oxidation of arsenite to arsenate using tunable K+ concentration in the OMS-2 tunnel.

    Cryptomelane-type octahedral molecular sieve manganese oxide (OMS-2) possesses high redox potential and has attracted much interest in its application for oxidation arsenite (As(III)) species of arsenic to arsenate (As(V)) to decrease arsenic toxicity and promote total arsenic removal. However, coexisting ions such as As(V) and phosphate are ubiquitous and readily bond to manganese oxide surface, consequently passivating surface active sites of manganese oxide and reducing As(III) oxidation. In this study, we present a novel strategy to significantly promote As(III) oxidation activity of OMS-2 by tuning K + concentration in the tunnel. Batch experimental results reveal that increasing K + concentration in the tunnel of OMS-2 not only considerably improved As(III) oxidation kinetics rate from 0.027 to 0.102 min -1 , but also reduced adverse effect of competitive ion on As(III) oxidation. The origin of K + concentration effect on As(III) oxidation was investigated through As(V) and phosphate adsorption kinetics, detection of Mn 2+ release in solution, surface charge characteristics, and density functional theory (DFT) calculations. Experimental results and theoretical calculations confirm that by increasing K + concentration in the OMS-2 tunnel not only does it improve arsenic adsorption on K + doped OMS-2, but also accelerates two electrons transfers from As(III) to each bonded Mn atom on OMS-2 surface, thus considerably improving As(III) oxidation kinetics rate, which is responsible for counteracting the adverse adsorption effects by coexisting ions.

  15. Ferrihydrite-associated organic matter (OM) stimulates reduction by Shewanella oneidensis MR-1 and a complex microbial consortia

    2017-11-01

    The formation of Fe(III) oxides in natural environments occurs in the presence of natural organic matter (OM), resulting in the formation of OM-mineral complexes that form through adsorption or coprecipitation processes. Thus, microbial Fe(III) reduction in natural environments most often occurs in the presence of OM-mineral complexes rather than pure Fe(III) minerals. This study investigated to what extent does the content of adsorbed or coprecipitated OM on ferrihydrite influence the rate of Fe(III) reduction by Shewanella oneidensis MR-1, a model Fe(III)-reducing microorganism, in comparison to a microbial consortium extracted from the acidic, Fe-rich Schlöppnerbrunnen fen. We found that increased OM content led to increased rates of microbial Fe(III) reduction by S. oneidensis MR-1 in contrast to earlier findings with the model organism Geobacter bremensis. Ferrihydrite-OM coprecipitates were reduced slightly faster than ferrihydrites with adsorbed OM. Surprisingly, the complex microbial consortia stimulated by a mixture of electrons donors (lactate, acetate, and glucose) mimics S. oneidensis under the same experimental Fe(III)-reducing conditions suggesting similar mechanisms of electron transfer whether or not the OM is adsorbed or coprecipitated to the mineral surfaces. We also followed potential shifts of the microbial community during the incubation via 16S rRNA gene sequence analyses to determine variations due to the presence of adsorbed or coprecipitated OM-ferrihydrite complexes in contrast to pure ferrihydrite. Community profile analyses showed no enrichment of typical model Fe(III)-reducing bacteria, such as Shewanella or Geobacter sp., but an enrichment of fermenters (e.g., Enterobacteria) during pure ferrihydrite incubations which are known to use Fe(III) as an electron sink. Instead, OM-mineral complexes favored the enrichment of microbes including Desulfobacteria and Pelosinus sp., both of which can utilize lactate and acetate as an electron

  18. Meditation on OM: Relevance from ancient texts and contemporary science

    Directory of Open Access Journals (Sweden)

    Kumar Sanjay

    2010-01-01

    Full Text Available Background: In Indian scriptures the sacred syllable Om is the primordial sound from which all other sounds and creation emerge which signifies the Supreme Power. Aims: To explore the significance of the syllable OM from ancient texts and effects of OM meditation in contemporary science. Descriptions from ancient texts: The descriptions of Om have been taken from four Upanisads (Mundaka, Mandukya, Svetasvatara, and Katha, the Bhagvad Gita, and Patanjali′s Yoga Sutras. Scientific studies on Om: Autonomic and respiratory studies suggest that there is a combination of mental alertness with physiological rest during the practice of Om meditation. Evoked potentials studies suggest a decrease in sensory transmission time at the level of the auditory association cortices, along with recruitment of more neurons at mesencephalic-diencephalic levels. Conclusion: It is considered that a person who realizes Om, merges with the Absolute. Scientific studies on Om suggest that the mental repetition of Om results in physiological alertness, and increased sensitivity to sensory transmission.

    The nanostructured Ce ion substituted cryptomelane-type octahedral molecular sieve (OMS-2) catalyst exhibits strong absorption in the entire solar spectrum region. The Ce ion substituted OMS-2 catalyst can efficiently transform the absorbed solar energy to thermal energy, resulting in a considerable increase of temperature. By combining the efficient photothermal conversion and thermocatalytic activity of the Ce ion substituted OMS-2 catalyst, we carried out full solar spectrum, visible-infrared, and infrared light driven catalysis with extremely high efficiency. Under the irradiation of full solar spectrum, visible-infrared, and infrared light, the Ce ion substituted OMS-2 catalyst exhibits extremely high catalytic activity and excellent durability for the oxidation of volatile organic pollutants such as benzene, toluene, and acetone. Based on the experimental evidence, we propose a novel mechanism of solar light driven thermocatalysis for the Ce ion substituted OMS-2 catalyst. The reason why the Ce ion substituted OMS-2 catalyst exhibits much higher catalytic activity than pure OMS-2 and CeO2/OMS-2 nano composite under the full solar spectrum irradiation is discussed.The nanostructured Ce ion substituted cryptomelane-type octahedral molecular sieve (OMS-2) catalyst exhibits strong absorption in the entire solar spectrum region.

    The potential and mechanism of synthesized magnetic octahedral molecular sieve (Fe 3 O 4 @OMS-2) nanoparticles in enhancing the aerobic microbial ability of sequencing batch reactor (SBR) for treating dye wastewater have been revealed in this study. The addition of Fe 3 O 4 @OMS-2 of 0.25g/L enhanced the decolorization of SBRs with an operation cycle of 24h by more than 20%. The 16S rRNA gene high-throughput sequencing indicated Fe 3 O 4 @OMS-2 increased the microbial richness and diversity of SBRs, and more importantly, promoted the potential dye-degrading bacteria. After a series of enriching and screening, four bacterial strains with the considerable decolorizing ability were isolated from SBRs, designating Alcaligenes faecalis FP-G1, Bacillus aryabhattai FP-F1, Escherichia fergusonii FP-D1 and Rhodococcus ruber FP-E1, respectively. The growth and decolorization of these pure strains were promoted in the presence of Fe 3 O 4 @OMS-2, which agrees with the result of high-throughput sequencing. Monitoring dissolved Fe/Mn ions and investigating the change of oxidation states of Fe/Mn species discovered OMS-2 composition played the critical role in modulating the microbial community. The significant enhancement of Mn-oxidizing/-reducing bacteria suggested microbial Mn redox may be the key action mechanism of Fe 3 O 4 @OMS-2, which can provide numerous benefits for the microbial community and decolorization of SBRs.

    Peptidoglycan recognition proteins (PGRPs), a group of pattern recognition receptors (PRRs), are innate immune molecules that are structurally conserved through evolution in both invertebrate and vertebrate animals. In teleost fish, several PGRPs have been characterized recently. They have both amidase activity and bactericidal activity and are involved in indirectly killing bacteria and regulating multiple signaling pathways. However, the knowledge of functional similarity and divergence between PGRP paralogs for their role as an immune modulator in teleost fish is still limited. In this study, we identified a novel PGRP paralog, termed OmPGRP-L2 from the rainbow trout (Oncorhynchus mykiss). OmPGRP-L2 contains the conserved PGRP domain and the four Zn 2+ -binding amino acid residues required for amidase activity. Quantitative RT-PCR analysis indicated that OmPGRP-L2 is highly expressed in liver. Overexpression of OmPGRP-L2 in a rainbow trout hepatocyte cell line RTH-149 challenged with Edwardsiella tarda resulted in down-regulation of IL-1β and TNF-α expression. When overexpressed in RTH-149 cells, OmPGRP-L2 inhibited NF-κB activity with or without bacterial stimulation. Collectively, these findings suggest that OmPGRP-L2 has an immunomodulatory function, via NF-κB inhibition in liver. Copyright © 2017 Elsevier B.V. All rights reserved.

    The results of reactions between preformed cationic gold oxide clusters and carbon monoxide have been investigated utilizing a fast-flow reactor mass spectrometer. From these studies, it was found that all AunOm+ produced in the cluster source disappeared with CO addition at the reactant gas inlet. Furthermore, with CO addition, intermediate peaks of the form AunOm(CO)x+ (n=1-2, m=0-3, x=0-2) were produced, with some of the species continuing to react at higher CO flows.

    1991-01-01

    The study focuses on the use of an orbital maneuvering system (OMS) payload bay kit (PBK) designed to utilize OMS tanks identical to those currently employed in the Orbiter OMS pods. Emphasis is placed on payload deployment capability and payload servicing/reboost capability augmentation from the point of view of payload mass, maximum deployment altitudes, and initial retrieval and final deployment altitudes. The deployment, servicing, and reboost requirements of the Hubble Space Telescope and Advanced X-ray and Astrophysics Facility are analyzed in order to show the benefits an OMS PBK can provide for these missions. It is shown that OMS PBKs can provide the required capability enhancement necessary to support deployment, reboost, and servicing of payloads requiring altitudes greater than 325 nautical miles.

    In this study, CN-TiO₂ was modified with cryptomelane octahedral molecular sieves (OMS-2) by the sol-gel method based on the self-assembly technique to enhance its photocatalytic activity under the daylight irradiation. The synthesized samples were characterized by X-ray diffraction (XRD), UV-vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR) and porosimeter analysis. The results showed that the addition of OMS-2 in the sol lead to higher Brunauer-Emmett-Teller (BET) surface area, pore volume, porosity of particle after heat treatment and the specific surface area, porosity, crystallite size and pore size distribution could be controlled by adjusting the calcination temperature. Compared to the CN-TiO₂-400 sample, CN-TiO₂/OMS-2-400 exhibited greater red shift in absorption edge of samples in visible region due to the OMS-2 coated. The enhancement of photocatalytic activity of CN-TiO₂/OMS-2 composite photocatalyst was subsequently evaluated for the degradation of the methyl orange dye under the daylight irradiation in water. The results showed that the methyl orange dye degradation rate reach to 37.8% for the CN-TiO₂/OMS-2-400 sample under the daylight irradiation for 5 h, which was higher than that of reference sample. The enhancement in daylight photocatalytic activities of the CN-TiO₂/OMS samples could be attributed to the synergistic effects of OMS-2 coated, larger surface area and red shift in adsorption edge of the prepared sample.

Several conclusions are attained with respect to the kinetics of the pyrolysis decomposition, which was controlled according to the following steps: a) Gas evolution (hydrogen and hydrocarbons). B) Intermediate boiling compound formation, such as biphenyl, benzene.alkyl-benzenes, etc. c) high boiling compound evolution. d) Decreasing of starting material. In this way, comparative data en decomposition rate and activation energy of the pyrolysis phenomena are tabulated. (Author) 15 refs.

  6. Ferrihydrite-associated organic matter (OM stimulates reduction by Shewanella oneidensis MR-1 and a complex microbial consortia

    R. E. Cooper

    2017-11-01

    Full Text Available The formation of Fe(III oxides in natural environments occurs in the presence of natural organic matter (OM, resulting in the formation of OM–mineral complexes that form through adsorption or coprecipitation processes. Thus, microbial Fe(III reduction in natural environments most often occurs in the presence of OM–mineral complexes rather than pure Fe(III minerals. This study investigated to what extent does the content of adsorbed or coprecipitated OM on ferrihydrite influence the rate of Fe(III reduction by Shewanella oneidensis MR-1, a model Fe(III-reducing microorganism, in comparison to a microbial consortium extracted from the acidic, Fe-rich Schlöppnerbrunnen fen. We found that increased OM content led to increased rates of microbial Fe(III reduction by S. oneidensis MR-1 in contrast to earlier findings with the model organism Geobacter bremensis. Ferrihydrite–OM coprecipitates were reduced slightly faster than ferrihydrites with adsorbed OM. Surprisingly, the complex microbial consortia stimulated by a mixture of electrons donors (lactate, acetate, and glucose mimics S. oneidensis under the same experimental Fe(III-reducing conditions suggesting similar mechanisms of electron transfer whether or not the OM is adsorbed or coprecipitated to the mineral surfaces. We also followed potential shifts of the microbial community during the incubation via 16S rRNA gene sequence analyses to determine variations due to the presence of adsorbed or coprecipitated OM–ferrihydrite complexes in contrast to pure ferrihydrite. Community profile analyses showed no enrichment of typical model Fe(III-reducing bacteria, such as Shewanella or Geobacter sp., but an enrichment of fermenters (e.g., Enterobacteria during pure ferrihydrite incubations which are known to use Fe(III as an electron sink. Instead, OM–mineral complexes favored the enrichment of microbes including Desulfobacteria and Pelosinus sp., both of which can utilize lactate and

    Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disease in childhood which can be associated with neuroblastoma. Since autoantibodies have been detected in some patients with OMS, an autoimmune etiology is suspected. We compared the prevalence of autoimmune disorders and autoantibodies in parents of children with OMS and in a group of controls of same age and sex. Autoimmune diseases were found in 15.8% of the parents of OMS children, but only in 2.0% of the controls (pOMS parents (42.8% vs. 8.0%, pOMS parents also had significantly more autoantibodies against CNS structures than the controls (pOMS and may also hint to a genetic susceptibility for OMS.

    2016-05-01

    This study presents a simplified approach for size-controlled synthesis of manganese oxide octahedral molecular sieve (OMS-2) nanowires using potassium permanganate (KMnO4) and different inorganic acids (HCl, HNO3, and H2SO4) under reflux conditions. The morphology and nanostructure of the synthesized products are characterized by X-ray diffraction, Ar adsorption, and electron microscopy analysis, in order to elucidate the controlling effects of acid concentration and type as well as the formation mechanism of OMS-2 nanowires. The concentration of inorganic acid is a crucial factor controlling the phase of the synthesized products. OMS-2 nanowires are obtained with HCl at the concentration ≥0.96 mol/L or with HNO3 and H2SO4 at the concentrations ≥0.72 mol/L. Differently, the type of inorganic acid effectively determines the particle size of OMS-2 nanowires. When the acid is changed from HCl to HNO3 and H2SO4 in the reflux system, the average length of OMS-2 declines significantly by 60-70% (1104-442 and 339 nm), with minor decreased in the average width (43-39 and 34 nm). The formation of OMS-2 nanowires under reflux conditions with KMnO4 and inorganic acids involves a two-step process, i.e., the initial formation of layered manganese oxides, and subsequent transformation to OMS-2 via a dissolution-recrystallization process under acidic conditions. The proposed reflux route provides an alternative approach for synthesizing OMS-2 nanowires as well as other porous nano-crystalline OMS materials.

  13. Effects of precursor and sulfation on OMS-2 catalyst for oxidation of ethanol and acetaldehyde at low temperatures.

    Science.gov (United States)

    Wang, Renhu; Li, Junhua

    2010-06-01

    Volatile organic compounds (VOCs) emitted from many industrial processes and transportation activities are major organic pollutants in the atmosphere and toxic to human health. Octahedral molecular sieve (OMS-2) catalysts with different precursors and sulfate-acidified OMS-2 catalysts were synthesized using refluxing methods. The catalysts were investigated on complete oxidation of ethanol and acetaldehyde, and both demonstrated good reactivity. However, acidification resulted in a decrease in activity. OMS-2 catalyst using MnSO(4) as precursor exhibited the best catalytic performance and, thus, was selected for catalyst deactivation by sulfur dioxide. The results of this study suggested that the Mn-O bond of OMS-2 catalysts was the main determinant of the catalytic activity toward oxygenated VOC oxidation and weaker acid sites benefited higher acetaldehyde selectivity. Catalyst deactivation resulted from a strong but slow chemical interaction between the Mn-O bond and sulfur dioxide, probably forming manganese sulfate.

  14. Ordered micro/macro porous K-OMS-2/SiO2 nanocatalysts: Facile synthesis, low cost and high catalytic activity for diesel soot combustion

    Science.gov (United States)

    Yu, Xuehua; Zhao, Zhen; Wei, Yuechang; Liu, Jian

    2017-04-01

    A series of novel oxide catalysts, which contain three-dimensionally ordered macroporous (3DOM) and microporous structure, were firstly designed and successfully synthesized by simple method. In the as-prepared catalysts, 3DOM SiO2 is used as support and microporous K-OMS-2 oxide nanoparticles are supported on the wall of SiO2. 3DOM K-OMS-2/SiO2 oxide catalysts were firstly used in soot particle oxidation reaction and they show very high catalytic activities. The high activities of K-OMS-2/SiO2 oxide catalysts can be assigned to three possible reasons: macroporous effect of 3DOM structure for improving contact between soot and catalyst, microporous effect of K-OMS-2 for adsorption of small gas molecules and interaction of K and Mn for activation of gas molecules. The catalytic activities of catalysts are comparable to or even higher than noble metal catalyst in the medium and high temperature range. For example, the T50 of K-OMS-2/SiO2-50, 328 °C, is much lower than those of Pt/Al2O3 and 3DOM Au/LaFeO3, 464 and 356 °C,respectively. Moreover, catalysts exhibited high catalytic stability. It is attributed to that the K+ ions are introduced into the microporous structure of OMS-2 and stabilized in the catalytic reaction. Meanwhile, the K+ ions play an important role in templating and stabilizing the tunneled framework of OMS-2.

    An Operations Management System (OMS) is being designed for Space Station Freedom to improve productivity, reliability, and safety while reducing operations and maintenance costs. Central to the concept is a short term plan containing mixes of man-readable and machine-executable procedures used in an environment of distributed processing and execution. An OMS event evaluator to check upcoming short-term plan events for validity of execution is under development. The first version checks time and resource constraints against operational conditions for current or expected stations. In work are the handling of environmental and other operational constraints, as well as detailed modeling of resources and station operational states.

  2. Quantification of amine functional groups and their influence on OM/OC in the IMPROVE network

    Science.gov (United States)

    Kamruzzaman, Mohammed; Takahama, Satoshi; Dillner, Ann M.

    2018-01-01

    Recently, we developed a method using FT-IR spectroscopy coupled with partial least squares (PLS) regression to measure the four most abundant organic functional groups, aliphatic C-H, alcohol OH, carboxylic acid OH and carbonyl C=O, in atmospheric particulate matter. These functional groups are summed to estimate organic matter (OM) while the carbon from the functional groups is summed to estimate organic carbon (OC). With this method, OM and OM/OC can be estimated for each sample rather than relying on one assumed value to convert OC measurements to OM. This study continues the development of the FT-IR and PLS method for estimating OM and OM/OC by including the amine functional group. Amines are ubiquitous in the atmosphere and come from motor vehicle exhaust, animal husbandry, biomass burning, and vegetation among other sources. In this study, calibration standards for amines are produced by aerosolizing individual amine compounds and collecting them on PTFE filters using an IMPROVE sampler, thereby mimicking the filter media and collection geometry of ambient standards. The moles of amine functional group on each standard and a narrow range of amine-specific wavenumbers in the FT-IR spectra (wavenumber range 1 550-1 500 cm-1) are used to develop a PLS calibration model. The PLS model is validated using three methods: prediction of a set of laboratory standards not included in the model, a peak height analysis and a PLS model with a broader wavenumber range. The model is then applied to the ambient samples collected throughout 2013 from 16 IMPROVE sites in the USA. Urban sites have higher amine concentrations than most rural sites, but amine functional groups account for a lower fraction of OM at urban sites. Amine concentrations, contributions to OM and seasonality vary by site and sample. Amine has a small impact on the annual average OM/OC for urban sites, but for some rural sites including amine in the OM/OC calculations increased OM/OC by 0.1 or more.

    B-cell dysregulation has been implicated but not fully characterized in pediatric opsoclonus-myoclonus syndrome (OMS), a neuroblastoma-associated neuroinflammatory disorder. To assess the role of B-cell activating factor (BAFF) and a proliferation-inducing ligand (APRIL), two critical B cell-modulating cytokines, as potential biomarkers of disease activity and treatment biomarkers in OMS. Soluble BAFF and APRIL were measured in cerebrospinal fluid (CSF) and serum by ELISA in 433 children (296 OMS, 109 controls, 28 other inflammatory neurological disorders (OIND)). BAFF-R receptors on circulating CD19+ B cells were measured by flow cytometry. A blinded scorer rated motor severity on the OMS Evaluation Scale. Immunotherapies were evaluated cross-sectionally and longitudinally. The mean CSF BAFF concentration, which was elevated in untreated OMS and OIND, correlated with OMS severity category (P = 0.006), and reduction by adrenocorticotropic hormone or corticotropin (ACTH) (-61%) or corticosteroids (-38%) was seen at each level of severity. In contrast, CSF APRIL was normal in OMS and OIND and unaffected by immunotherapy. When the entire OMS dataset was dichotomized into 'high' versus 'normal' CSF BAFF concentration, the phenotype of the high group included greater motor severity and number of CSF oligoclonal bands, and a higher concentration of inflammatory chemokines CXCL13 and CXCL10 in CSF and CXCL9 and CCL21 in serum. Serum APRIL was 6.7-fold higher in the intravenous immunoglobulins (IVIg) group, whereas serum BAFF was 2.6-fold higher in the rituximab group. The frequency of B cell BAFF-R expression was similar in untreated and treated OMS. Longitudinal studies of CSF BAFF revealed a significant decline in ACTH-treated patients (with or without rituximab) (P OMS displayed heterogeneity in CSF BAFF expression, which met many but not all criteria as a potential biomarker of disease activity. We speculate that CSF BAFF may have more utility in a biomarker panel

    In the presence of manganese oxide octahedral molecular sieve (OMS-2) supported copper hydroxide Cu(OH) x /OMS-2, aerobic synthesis of benzoxazoles from catechols and amines via domino oxidation/cyclization at room temperature is achieved. This heterogeneous benzoxazoles synthesis initiated by the efficient oxidation of catechols over Cu(OH) x /OMS-2 tolerates a variety of substrates, especially amines containing sensitive groups (hydroxyl, cyano, amino, vinyl, ethynyl, ester, and even acetyl groups) and heterocycles, which affords functionalized benzoxazoles in good to excellent yields by employing low catalyst loading (2 mol % Cu). The characterization and plausible catalytic mechanism of Cu(OH) x /OMS-2 are described. The notable features of our catalytic protocol such as the use of air as the benign oxidant and EtOH as the solvent, mild conditions, ease of product separation, being scalable up to the gram level, and superior reusability of catalyst (up to 10 cycles) make it more practical and environmentally friendly for organic synthesis.

    In this study, the preloading effects of different fractions of wastewater effluent organic matter (EfOM) on the adsorption of trace-level pharmaceutically active compounds (PhACs) onto granular activated carbon (GAC) were investigated. A nanofiltration (NF) membrane was employed to separate the EfOM by size, and two GACs with distinct pore structures were chosen for comparison. The results showed that preloading with EfOM substantially decreased PhAC uptake of the GACs; however, comparable PhAC adsorption capacities were achieved on GACs preloaded by feed EfOM and the NF-permeating EfOM. This indicates that: (1) the NF-rejected, larger EfOM molecules with an expectation to block the PhAC adsorption pores exerted little impact on the adsorbability of PhACs; (2) the smaller EfOM molecules present in the NF permeate contributed mainly to the decrease in PhAC uptake, mostly due to site competition. Of the two examined GACs, the wide pore-size-distributed GAC was found to be more susceptible to EfOM preloading than the microporous GAC. Furthermore, among the fourteen investigated PhACs, the negatively charged hydrophilic PhACs were generally subjected to a greater EfOM preloading impact. Copyright © 2016 Elsevier Ltd.

    A heterogeneous magnetic CuFe2O4@OMS-2 catalyst was fabricated through a facile solvent-free process using Mn(CH3COO)2 and KMnO4 in the presence of CuFe2O4. It was found that the BET surface area of OMS-2 as well as the ratio of low-valent manganese species significantly increased in the hybrid catalyst, due to interactions between CuFe2O4 and the precursor of amorphous manganese oxide. Acid Orange 7 (AO7) and other organic pollutants could be completely degraded by the CuFe2O4@OMS-2 catalyst within 30 min in the presence of peroxymonosulfate (PMS), while CuFe2O4 and OMS-2 showed no significant activity for the reaction. The hybrid catalyst also exhibited excellent long-term stability and could be easily recovered with the assistance of an external magnetic field. A possible degradation mechanism for the synergistic effects of different valent metal species and reactive radicals was proposed, which involved the electron transfer from Mn(III) or Mn(II) species to PMS with the generation of sulfate and hydroxyl radicals, and from AO7 and Cu(I) in CuFe2O4 to Mn(IV) and Mn(III) to reduce these Mn species.

    Purpose This study aimed to investigate the effect of OM-101 on the fibrotic response occurring in proliferative vitreoretinopathy (PVR) in an animal model. Methods Antifibrotic effect of OM-101 was investigated in vivo. As control, eight weeks old c57black mice underwent intravitreal injection with Hepes (group A) or dispase (0.3 units), to induce retinal detachment (RD) and PVR. The dispase-injected mice were randomly divided into two groups B and C (N = 25 mice); in group C, the eyes were treated with intravitreal injection of OM-101 (3 μl), and group B with PBS, as a control. After additional five days, mice were injected with the same initial treatment. Three days later, mice were euthanized, and the eyes were enucleated and processed for histological analysis. Results Intravitreal injection of dispase caused RD in 64% of the mice in group B, and 93% of those mice had PVR. Only 32% of mice treated with OM-101 and dispase (group C) developed RD, and only 25% of those developed PVR. Conclusions OM-101 was found effective in reducing the incidence of RD and PVR maintaining the normal architecture of the retina. This study suggests that OM-101 is a potentially effective and safe drug for the treatment of PVR patients. PMID:29109865

    Graphical abstract: Oxidation of various alcohols is studied in the liquid phase over new composite mixed oxide (V 2 O 5 /OMS-2) catalyst using tert-butyl hydroperoxide (TBHP). The activity of V 2 O 5 /OMS-2 samples was considerably increased with respect to OMS-2 catalyst and these samples are found to be suitable for the selective oxidation of alcohols. - Highlights: • V 2 O 5 /K-OMS-2 with different V/Mn molar ratios prepared by the impregnation method. • Oxidation of alcohols was studied in the liquid phase over V 2 O 5 /K-OMS-2 catalyst. • V 2 O 5 /K-OMS-2 catalyst had excellent activity for alcohol oxidation. • Benzyl alcohol oxidation using excess TBHP followed a pseudo-first order kinetic. • The selected catalyst was reused without significant loss of activity. - Abstract: This work reports the synthesis and characterization of mixed oxide vanadium–manganese V 2 O 5 /K-OMS-2 at various V/Mn molar ratios and prepared by the impregnation method. Characterization of these new composite materials was made by elemental analysis, BET, XRD, FT-IR, SEM and TEM techniques. Results of these analyses showed that vanadium impregnated samples contained mixed phases of cryptomelane and crystalline V 2 O 5 species. Oxidation of various alcohols was studied in the liquid phase over the V 2 O 5 /K-OMS-2 catalyst using tert-butyl hydroperoxide (TBHP) and H 2 O 2 as the oxidant. Activity of the V 2 O 5 /K-OMS-2 samples was increased considerably with respect to K-OMS-2 catalyst due to the interaction of manganese oxide and V 2 O 5 . The kinetic of benzyl alcohol oxidation using excess TBHP over V 2 O 5 /K-OMS-2 catalyst was investigated at different temperatures and a pseudo-first order reaction was determined with respect to benzyl alcohol. The effects of reaction time, oxidant/alcohol molar ratio, reaction temperature, solvents, catalyst recycling potential and leaching were investigated

    1999-01-01

    NASA is pursuing the technology and advanced development of a non-toxic (NT) orbital maneuvering system (OMS) and reaction control system (RCS) for shuttle upgrades, RLV, and reusable first stages. The primary objectives of the shuttle upgrades program are improved safety, improved reliability, reduced operations time and cost, improved performance or capabilities, and commonality with future space exploration needs. Non-Toxic OMS/RCS offers advantages in each of these categories. A non-toxic OMS/RCS eliminates the ground hazards and the flight safety hazards of the toxic and corrosive propellants. The cost savings for ground operations are over $24M per year for 7 flights, and the savings increase with increasing flight rate up to $44M per year. The OMS/RCS serial processing time is reduced from 65 days to 13 days. The payload capability can be increased up to 5100 Ibms. The non-toxic OMS/RCS also provides improved space station reboost capability up to 20 nautical miles over the current toxic system of 14 nautical miles. A NT OMS/RCS represents a clear advancement in the SOA over MMH/NTO. Liquid oxygen and ethanol are clean burning, high-density propellants that provide a high degree of commonality with other spacecraft subsystems including life support, power, and thermal control, and with future human exploration and development of space missions. The simple and reliable pressure-fed design uses sub-cooled liquid oxygen at 250 to 350 psia, which allows a propellant to remain cryogenic for longer periods of time. The key technologies are thermal insulation and conditioning techniques are used to maintain the sub-cooling. Phase I successfully defined the system architecture, designed an integrated OMS/RCS propellant tank, analyzed the feed system, built and tested the 870 lbf RCS thrusters, and tested the 6000 lbf OMS engine. Phase 11 is currently being planned for the development and test of full-scale prototype of the system in 1999 and 2000

    The cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2)-supported Pd (0.5 wt% Pd/OMS-2-DP, 0.5 wt% Pd/OMS-2-PI, and 0.5 wt% Pd/OMS-2-EX) catalysts were prepared by the deposition-precipitation, pre-incorporation, and ion-exchanging strategies, respectively. It is shown that the preparation method exerted an important effect on the physicochemical property of the sample. Among the OMS-2-supported Pd catalysts, 0.5 wt% Pd/OMS-2-DP possessed the highest surface (Mn2+ + Mn3+)/Mn4+ atomic ratio and the highest surface Pd loading and acid sites. The 0.5 wt% Pd/OMS-2 catalysts outperformed the Pd-free counterpart, among which 0.5 wt% Pd/OMS-2-DP presented the best catalytic activity (T50% and T90% were 25 and 55 °C for CO oxidation, 240 and 285 °C for toluene oxidation, and 160 and 200 °C for ethyl acetate oxidation, respectively). We believe that the high Pd surface loading, high surface atomic ratio of (Mn2+ + Mn3+)/Mn4+, and good low-temperature reducibility, good oxygen mobility, and high acidity were responsible for the excellent performance of the 0.5 wt% Pd/OMS-2-DP catalyst.

  2. Contribution of effluent organic matter (EfOM) to ultrafiltration (UF) membrane fouling: Isolation, characterization, and fouling effect of EfOM fractions

    KAUST Repository

    Zheng, Xing

    2014-11-01

    EfOM has been regarded as a major organic foulant resulting in UF membrane fouling in wastewater reclamation. To investigate fouling potential of different EfOM fractions, the present study isolated EfOM into hydrophobic neutrals (HPO-N), colloids, hydrophobic acids (HPO-A), transphilic neutrals and acids (TPI), and hydrophilics (HPI), and tested their fouling effect in both salt solution and pure water during ultrafiltration (UF). Major functional groups and chemical structure of the isolates were identified using Fourier transform infrared spectroscopy (FT-IR) and solid-state carbon nuclear magnetic resonance (13C NMR) analysis. The influence of the isolation process on the properties of EfOM fractions was minor because the raw and reconstituted secondary effluents were found similar with respect to UV absorbance, molecular size distribution, and fluorescence character. In membrane filtration tests, unified membrane fouling index (UMFI) and hydraulic resistance were used to quantify irreversible fouling potential of different water samples. Results show that under similar DOC level in feed water, colloids present much more irreversible fouling than other fractions. The fouling effect of the isolates is related to their size, chemical properties, and solution chemistry. Further investigations have identified that the interaction between colloids and other fractions also influences the performance of colloids in fouling phenomena. © 2014 Elsevier Ltd.

    Curtis, Leslie A.; Hurlbert, Eric A.

    1999-01-01

    NASA is pursuing non-toxic propellant technologies applicable to RLV and Space Shuttle orbital maneuvering system (OMS) and reaction control system (RCS). The primary objectives of making advancements in an OMS/RCS system are improved safety, reliability, and reduced operations and maintenance cost, while meeting basic operational and performance requirements. An OMS/RCS has a high degree of direct interaction with the vehicle and crew and requires subsystem and components that are compatible with integration into the vehicle with regard to external mold-line, power, and thermal control. In July 1997, a Phase I effort for the technology and advanced development of an upgrade of the space shuttle was conducted to define the system architecture, propellant tank, feed system, RCS thrusters, and OMS engine. Phase I of the project ran from July 1997 to October 1998. Phase II is currently being planned for the development and test of full-scale prototype of the system in 1999 and 2000. The choice of pressure-fed liquid oxygen (LO2) and ethanol is the result of numerous trade studies conducted from 1980 to 1996. Liquid oxygen and ethanol are clean burning, high-density propellants that provide a high degree of commonality with other spacecraft subsystems including life support, power, and thermal control, and with future human exploration and development of space missions. The key to this pressure-fed system is the use of subcooled liquid oxygen at 350 psia. In this approach, there is 80 degrees R of subcooling, which means that boil-off will not occur until the temperature has risen 80 R. The sub-cooling results naturally from loading propellants at 163 R, which is the saturation temperature at 14.7 psia, and then pressurizing to 350 psia on the launch pad. Thermal insulation and conditioning techniques are then used to limit the LO2 temperature to 185 R maximum, and maintain the sub-cooling. The other key is the wide temperature range of ethanol, -173 F to +300 F, which

  10. Kampen om matfatet og matproduksjonen

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available Antallet sultne i verden har økt, selv om det kan diskuteres om det i dag er en høyere eller lavere andel som lider under sult enn for seks år siden – før matprisøkningen. Alle er uansett enige om at det samlet sett produseres nok mat i verden til at alle kan få dekket sine ernæringsbehov. Artikkelen viser at to hovedretninger i debatten om matproduksjon står mot hverandre. Den dominerende retningen fokuserer primært på matsikkerhet, forstått som økt matproduksjon og økt handel med mat. Den andre retningen argumenterer for at interessene og rettighetene for de mest sårbare må ha forrang i politiske prioriteringer, og at de sårbare sikres best med en strategi basert på menneskerettigheter. Artikkelen drøfter landfordeling, økt bruk av genteknologi i landbruket og nedbygging av handelshindre for landbruksprodukter. Industrialisering av landbruket og liberalisering av handelen med landbruksvarer kan gi gode resultater på makronivå – på kort sikt. Dersom målet er å fremme situasjonen for de mest sårbare og samtidig møte klimautfordringene er løsningen en nedenfra-tilnærming, som til nå er blitt ignorert av de fleste stater.Nøkkelord: retten til mat, matsikkerhet, klima, Verdens handelsorganisasjon, FNs tusenårsmålEnglish summary: The struggle over food intake and food productionThe number of hungry persons in the world has increased – although it is debatable whether there is currently a higher or lower proportion of suffering from hunger than six years ago – before the food price increases. All agree that the overall production of food in the world is adequate for everyone's nutritional needs. The article demonstrates that there are two main approaches in the debate on food production. The dominant approach focuses primarily on food security, understood as increased food production and increased food trade. The other approach argues that the interests and rights of the most vulnerable must prevail, and that

  12. LHCb: Evaluation of 400m, 5Gbit Versatile Link lengths over OM3 and OM4 fibres for the LHCb upgrade

    CERN Multimedia

    Schwemmer, R; Neufeld, N; Soos, C; Troska, J; Wyllie, K

    2013-01-01

    The LHCb experiment will upgrade its DAQ system to a trigger less, 40MHz read-out after LS2. To be able to process the approximately 40Tbit/s of data we will require a massive computing farm. This computing farm can not be installed underground, in the vicinity of the detector anymore due to the enormous power and cooling requirements. An affordable data transport solution has to be found to carry the data from the detector to the new data center on the surface. The distance to cover is estimated to be between 300 and 400 meters. We evaluated the feasibility of using the 5Gbit/s Versatile Link to cover the full distance over OM3 and OM4 quality fibres and will present our results.

  13. Ultra-Wideband Optical Modulation Spectrometer (OMS) Development

    Science.gov (United States)

    Gardner, Jonathan (Technical Monitor); Tolls, Volker

    2004-01-01

    The optical modulation spectrometer (OMS) is a novel, highly efficient, low mass backend for heterodyne receiver systems. Current and future heterodyne receiver systems operating at frequencies up to a few THz require broadband spectrometer backends to achieve spectral resolutions of R approximately 10(exp 5) to 10(exp 6) to carry out many important astronomical investigations. Among these are observations of broad emission and absorption lines from extra-galactic objects at high redshifts, spectral line surveys, and observations of planetary atmospheres. Many of these lines are pressure or velocity broadened with either large half-widths or line wings extending over several GHz. Current backend systems can cover the needed bandwidth only by combining the output of several spectrometers, each with typically up to 1 GHz bandwidth, or by combining several frequency-shifted spectra taken with a single spectrometer. An ultra-wideband optical modulation spectrometer with 10 - 40 GHz bandwidth will enable broadband ob- servations without the limitations and disadvantages of hybrid spectrometers. Spectrometers like the OMS will be important for both ground-based observatories and future space missions like the Single Aperture Far-Infrared Telescope (SAFIR) which might carry IR/submm array heterodyne receiver systems requiring a spectrometer for each array pixel. Small size, low mass and small power consumption are extremely important for space missions. This report summarizes the specifications developed for the OMS and lists already identified commercial parts. The report starts with a review of the principle of operation, then describes the most important components and their specifications which were derived from theory, and finishes with a conclusion and outlook.

  17. Å skape et begrep om jam i utforskningen av en deleuziansk metode-ontologi

    Directory of Open Access Journals (Sweden)

    Ola Harstad

    2017-12-01

    Full Text Available Å forske med kunsten innebærer ikke bare valget av visse metoder for bruk i forskningsprosessen, men også om å ha til disposisjon spesifikke måter å tenke om metode. I denne artikkelen vil jeg synliggjøre en tenkemåte fundert i arbeidet med en skjønnlitterær lesesirkel for lærerstudenter, og min egen erfaring som improvisasjonsmusiker. Jazzens begrep om jam blir løftet frem som omdreiningspunkt for tenkemåten, som ellers har sitt teoretiske utspring i den franske filosofen Gilles Deleuze’s forestilling om bliven. Denne vitale forestillingen innebærer at verden produseres kontinuerlig, noe forskeren også bidrar til. Koblingen mellom jam, litteratur og Deleuze synliggjør dessuten en måte å tenke om metode på som understreker at det å forske med kunsten ikke bare betyr å forske på kunsten, men at kunsten på ulike måter kan virke inn på selve forskningen og slik også bidra til å affirmere verden i sin bliven. I tillegg til å tilby en måte å tenke om metode for den som skal forske med kunsten, er hensikten med artikkelen å gjøre forskeren bevisst sin egen tenkning om metode, noe som er viktig siden denne skaper mulighetsbetingelser for metodevalg og -bruk.

    2012-01-01

    Highlights: ► The influence of high temperature exposure on OM4 fibers’ mechanical properties. ► Researching OM4 class fibers for use in innovative Optical Multi Chip Module. ► The influence of bending at a very small radius, up to 2 mm, on MM fibers. - Abstract: For future generations of electronic systems, a severe bottleneck is expected on the interconnection level and the use of optical interconnection is considered as one of the most promising solutions in this matter. Recent progress in fiber development resulted in new generation of optical fibers that are bend insensitive. This makes them ideal for Multi Chip Module (MCM) application. This paper focuses on OM4 bend insensitive multi-mode fibers’ usefulness for MCM integration, particularly the investigation of MM fiber loss is presented, which is influenced by bend diameter and the fiber's mechanical performance under influence of high temperature (400 °C–1000 °C adequate to MCM production process).

    En central antagelse for både filosofiske og folkepsykologiske begreber om fri vilje er, at bevidste processer, beslutninger og intentioner kan have effekt på ens handlinger. Eksperimenter udført af Benjamin Libet og andre er blevet hævdet at modbevise dette, hvorved fri vilje skulle være umulig...... at foretrække det ene frem for det andet. Eksperimenternes resultater er derfor uden betydning for spørgsmålet om fri vilje.

    2017-05-01

    The human orbital muscle (OM) is not readily accessible during ordinary anatomical teaching because of insufficient time and difficulties encountered in the preparation. Accordingly, its few anatomical descriptions are supported only by drawings, but not by photographs. The aim of this study was to present OM in dissected anatomic specimens in more detail. Following microscope-assisted dissection, its location, syntopy and morphology were analyzed in 88 orbits of 51 cadavers. Together with the periorbital connective tissue OM filled the infraorbital fissure (IOF) and extended back to the cavernous sinus. As a new finding, we here report that in 34% of the orbits we observed OM-fibers, which proceeded from IOF caudally to the facies infratemporalis of the maxilla. OM had a mean width of 4±1mm, a mean length of 22±5mm and its mean mass was 0.22±0.19g. The subsequent histological analysis of all specimens showed features of smooth muscle tissue: long, spindle-like cells with a centrally located cell nucleus (hematoxylin-eosin staining) which were innervated by tyrosine-hydroxylase immunopositive adrenergic fibers. We conclude that precise knowledge on OM might be very helpful not only to students in medicine and dentistry during anatomical dissection courses, but also to head and neck surgeons, ear-nose-throat specialists and neurosurgeons working in this field.

    2014-11-01

    As greater numbers of photovoltaic (PV) systems are being installed, operations & maintenance (O&M) activities will need to be performed to ensure the PV system is operating as designed over its useful lifetime. To mitigate risks to PV system availability and performance, standardized procedures for O&M activities are needed to ensure high reliability and long-term system bankability. Efforts are just getting underway to address the need for standard O&M procedures as PV gains a larger share of U.S. generation capacity. Due to the existing landscape of how and where PV is installed, including distributed generation from small and medium PV systems, as well as large, centralized utility-scale PV, O&M activities will require different levels of expertise and reporting, making standards even more important. This report summarizes recent efforts made by solar industry stakeholders to identify the existing standards and best practices applied to solar PV O&M activities, and determine the gaps that have yet to be, or are currently being addressed by industry.

    The effects of the bacterial extract OM-85 on the respiratory burst, intracellular calcium and the stress response have been investigated in human peripheral blood monocytes from normal donors. Activation of the respiratory burst during bacterial phagocytosis has been previously associated with heat shock/stress proteins synthesis. Whereas OM-85 stimulated superoxide production and increased Ca2+ mobilization, it fared to induce synthesis of classical HSPs. The lack of stress protein induction was observed even in the presence of iron which potentiates both oxidative injury and stress protein induction during bacterial phagocytosis. However OM-85 induced a 75–78 kDa protein, which is likely to be a glucose regulated protein (GRP78), and enhanced intracellular expression of interleukin-lβ precursor. PMID:18472933

    2010-01-15

    Separation of carbon dioxide (CO(2)) from gaseous mixture is an important issue for the removal of CO(2) in natural gas processing and power plants. The ordered mesoporous silicas (OMS) with uniform pore structure and high density of silanol groups, have attracted the interest of researchers for separation of carbon dioxide (CO(2)) using adsorption process. These mesoporous silicas after functionalization with amino groups have been studied for the removal of CO(2). The potential of functionalized ordered mesoporous silica membrane for separation of CO(2) is also recognized. The present paper reviews the synthesis of mesoporous silicas and important issues related to the development of mesoporous silicas. Recent studies on the CO(2) separation using ordered mesoporous silicas (OMS) as adsorbent and membrane are highlighted. The future prospectives of mesoporous silica membrane for CO(2) adsorption and separation are also presented and discussed. Copyright 2009 Elsevier B.V. All rights reserved.

    As greater numbers of photovoltaic (PV) systems are being installed, operations & maintenance (O&M) activities will need to be performed to ensure the PV system is operating as designed over its useful lifetime. To mitigate risks to PV system availability and performance, standardized procedures for O&M activities are needed to ensure high reliability and long-term system bankability. Efforts are just getting underway to address the need for standard O&M procedures as PV gains a larger share of U.S. generation capacity. Due to the existing landscape of how and where PV is installed, including distributed generation from small and medium PV systems, as well as large, centralized utility-scale PV, O&M activities will require different levels of expertise and reporting, making standards even more important. This report summarizes recent efforts made by solar industry stakeholders to identify the existing standards and best practices applied to solar PV O&M activities, and determine the gaps that have yet to be, or are currently being addressed by industry.

  17. Drip Irrigation Aided Phytoremediation for Removal of TCE FR-om Groundwater

    Groundwater in D-Area at the Savannah River Site (SRS) is contaminated with trichloroethylene (TCE) and by-products resulting FR-om discharges of this organic solvent during past disposal practices. This contaminated groundwater occurs primarily at depths of 9 meters to 15 meters below ground surface, well below the depths that are typically penetrated by plant roots. The process investigated in this study involved pumping water FR-om the contaminated aquifer and discharging the water into overlying test plots two inches below the surface using drip irrigation. The field treatability study was conducted FR-om 8/31/00 to 4/18/02 using six 0.08 hectare test plots, two each containing pines, cottonwoods, and no vegetation (controls). The primary objective was to determine the overall effectiveness of the process for TCE removal and to determine the principal biotic and abiotic pathways for its removal. Results demonstrated that the process provides a viable method to remove TCE-contaminated groundwater. The data clearly showed that the presence of trees reduced volatilization of TCE FR-om the drip irrigation system to the atmosphere. Influent groundwater TCE concentrations averaging 89 mg/L were reduced to non-detectable levels (less than 5 mg/L) within the upper two feet of soil (rhizosphere)

    In 208 children with opsoclonus-myoclonus syndrome (OMS), CSF IgG oligoclonal bands (OCB) and 22 immunomarkers in CSF and 21 in serum/blood were measured. In 36 untreated OMS, 58% were OCB(+), whereas 55% of treated OMS were OCB(-). OCB positivity or negativity did not alter concentrations or frequencies of immunomarkers. The phenotypes of OCB(+) and OCB(-) patients were not distinctive. CSF B cells were expanded in untreated OMS regardless of OCB positivity. These data reveal a much higher frequency of OCB positivity in untreated OMS than previously realized and a disconnect between intrathecal OCB and inflammatory mediator production. Copyright © 2018.

    Ocular motor score (OMS) is a new clinical test protocol for evaluating ocular motor functions in children and young adults. OMS is a set of 15 important and relevant non-invasive ocular motor function parameters derived from clinical practice. The aim of the study was to evaluate OMS according to intrarater and inter-rater agreement. Forty children aged 4-10 years, 23 girls median age 6.5 (range 4.3-9.3) and 17 boys median age 5.8 (range 4.1-9.8) were included. The ocular motor functions were assessed and scored according to the OMS protocol. The examinations were videotaped. To obtain the intrarater agreement, the first author examined and scored the children twice, first in the clinic and 2 weeks later by watching the videotape. To obtain the inter-rater agreement, three other raters independently scored the ocular motor function of the children by watching the videotapes. The overall observed intrarater agreement was 88%, and the observed inter-rater agreement between the three raters was 80%. For none of the subtests was there an observed intrarater agreement lower than 65%. Three of the subtests had an observed inter-rater agreement of 65% or below. Overall there was high observed intra- and inter-rater agreement for the OMS test protocol. Subtests such as saccades and smooth pursuit were more difficult for raters to score similarly according the clinical OMS test protocol. © 2015 Acta Ophthalmologica Scandinavica Foundation.

  4. Obesity-resistant S5B rats showed great cocaine conditioned place preference than the obesity-prone OM rats

    Dopamine (DA) and the DA D2 receptor (D2R) are involved in the rewarding and conditioned responses to food and drug rewards. Osborne-Mendel (OM) rats are genetically prone and S5B/P rats are genetically resistant to obesity when fed a high-fat diet. We hypothesized that the differential sensitivity of these two rat strains to natural rewards may also be reflected in sensitivity to drugs of abuse. Therefore, we tested whether OM and S5B/P rats showed a differential preference to cocaine using conditioned place preference (CPP). To also evaluate whether there is specific involvement of the D2R in this differential conditioning sensitivity, we then tested whether the D2R agonist bromocriptine (BC) would differentially affect the effects of cocaine in the two strains. OM and S5B/P rats were conditioned with cocaine (5 or 10 mg/kg) in one chamber and saline in another for 8 days. Rats were then tested for cocaine preference. The effects of BC (0.5, 1, 5, 10, 20 mg/kg) on cocaine preference were then assessed in subsequent test sessions. OM rats did not show a significant preference for the cocaine-paired chamber on test day. Only the S5B/P rats showed cocaine CPP. Later treatment with only the highest dose of BC resulted in reduced cocaine CPP in S5B/P rats when treated with 5 mg/kg cocaine and in OM rats treated with 10 mg/kg cocaine. Our results indicated that obesity-resistant S5B rats showed greater cocaine CPP than the obesity-prone OM rats. These findings do not support a theory of common vulnerability for reinforcer preferences (food and cocaine). However, they show that BC reduced cocaine conditioning effects supporting at least a partial regulatory role of D2R in conditioned responses to drugs.

    To study aberrant B cell trafficking into the CSF in opsoclonus-myoclonus syndrome (OMS), chemoattractants CXCL13 and CXCL12, and B cell frequency and CXCR5 expression, were evaluated. CSF CXCL13 concentration and the CSF/serum ratio were higher in untreated OMS than controls, related directly to OMS severity and inversely to OMS duration, and correlated with CSF B cell frequency and oligoclonal bands. CXCL12 showed the opposite pattern. Selective accumulation of CXCR5+ memory B cells in CSF was found. In ACTH-treated OMS, CXCL13, but not CXCL12, was lower. These data implicate the chemokine/chemoreceptor pair CXCL13/CXR5 in B cell recruitment to the CNS in OMS. CXCL13 and CXCL12 may serve as reciprocal biomarkers of disease activity, but CXCL13 also had utility as a treatment biomarker. Copyright © 2011 Elsevier B.V. All rights reserved.

    Mobile phone induced electromagnetic field (MPEMF) as well as chanting of Vedic mantra 'OM' has been shown to affect cognition and brain haemodynamics, but findings are still inconclusive. Twenty right-handed healthy teenagers (eight males and 12 females) in the age range of 18.25 ± 0.44 years were randomly divided into four groups: (1) MPONOM (mobile phone 'ON' followed by 'OM' chanting); (2) MPOFOM (mobile phone 'OFF' followed by 'OM' chanting); (3) MPONSS (mobile phone 'ON' followed by 'SS' chanting); and (4) MPOFSS (mobile phone 'OFF' followed by 'SS' chanting). Brain haemodynamics during Stroop task were recorded using a 64-channel fNIRS device at three points of time: (1) baseline, (2) after 30 min of MPON/OF exposure, and (3) after 5 min of OM/SS chanting. RM-ANOVA was applied to perform within- and between-group comparisons, respectively. Between-group analysis revealed that total scores on incongruent Stroop task were significantly better after OM as compared to SS chanting (MPOFOM vs MPOFSS), pre-frontal activation was significantly lesser after OM as compared to SS chanting in channel 13. There was no significant difference between MPON and MPOF conditions for Stroop performance, as well as brain haemodynamics. These findings need confirmation through a larger trial in future.

    To demonstrate the health economic impact of OM-85, a bacterial lysates based immunostimulant, for its approved indications in China. A cost-effectiveness decision tree model was constructed comparing OM-85 with the best supportive care/placebo therapy for managing the acute exacerbation of chronic bronchitis and rhinosinusitis in the Chinese population. Clinical efficacy and adverse events (AE) data were included in the model based on a thorough literature review. All localized direct treatment costs, including drug cost, AE costs, and medical treatment costs for underlining diseases were included from a Chinese third party payer perspective. A Key Opinion Leaders (KOL) survey was conducted with 20 senior physicians specialized in respiratory, ENT, allergy, and immunology fields from tertiary hospitals in Beijing, Shanghai, Guangzhou, Hangzhou, Shenyang, and Wuhan to validate the local treatment costs. Incremental cost-effectiveness ratio (ICER) was calculated based on the above efficacy and cost information. OM-85 is a cost-effective therapy when compared with placebo (standard care). OM-85 can treat/prevent one additional full episode exacerbation of chronic bronchitis and one additional full episode exacerbation of rhinosinusitis with only additional costs of RMB 653 and RMB 1182.84, respectively. In comparison, each acute exacerbation of chronic bronchitis will cost RMB 4510.10, and each acute exacerbation of rhinosinuisitis will cost RMB 1807.21 in a Chinese clinical management setting. One-way sensitivity analyses were performed and the ICER result was demonstrated to be consistent. OM 85 reduces acute exacerbations among patients with chronic bronchitis and chronic rhinosinusitis when compared with Placebo (standard care). From a Chinese payer perspective, OM 85 is a cost-effective therapy in the clinical management of both chronic bronchitis and rhinosinusitis in the adult population.

    This document outlines the foundation for developing language that can be utilized in an Equipment Availability Guarantee, typically included in an O&M services agreement between a PV system or plant owner and an O&M services provider, or operator. Many of the current PV O&M service agreement Availability Guarantees are based on contracts used for traditional power generation, which create challenges for owners and operators due to the variable nature of grid-tied photovoltaic generating technologies. This report documents language used in early PV availability guarantees and presents best practices and equations that can be used to more openly communicate how the reliability of the PV system and plant equipment can be expressed in an availability guarantee. This work will improve the bankability of PV systems by providing greater transparency into the equipment reliability state to all parties involved in an O&M services contract.

    Using a panel of seven brain cell-specific biomarkers in cerebrospinal fluid (CSF), pediatric opsoclonus-myoclonus syndrome (OMS) (n=234) was compared to pediatric non-inflammatory neurological controls (n=84) and other inflammatory neurological disorders (OIND) (n=44). Only CSF NFL was elevated in untreated OMS versus controls (+83%). It was 87% higher in OIND than in OMS. On combination treatment with front-loaded ACTH, IVIg, rituximab, median CSF NFL decreased by 60% to control levels. These biochemical data suggest neuronal/axonal injury in some children with OMS without indicators of astrogliosis, and reduction on sufficient immunotherapy. Copyright © 2013 Elsevier B.V.

  13. Seabed Filter Feasibility Study of Om Almisk Island

    KAUST Repository

    Sesler, Kathryn

    2012-06-01

    Freshwater access has always been and is continuing to be a severe problem in desert coastal regions, despite the fact that they have an unlimited supply of easily accessible saline water. Water desalination plants are well established and heavily relied upon throughout the Middle East, Saudi Arabia in particular. However, water desalination tends to be a very expensive and energy intensive solution to the problem. The transition from using open water intake systems and all of the pretreatment processes that they require, to using seabed water filters as an intake, would potentially reduce the lifetime costs, energy consumption, and environmental impacts commonly associated with water desalination. This is because the filtration process that the seabed filter generates, serves as sufficient pretreatment for seawater as well as eliminating any risk of entrainment or impingement of marine organisms. The main objective of this research is to conduct a feasibility study on Om Almisk Island, an island off the coast of King Abdullah University of Science and Technology (KAUST), to determine if it would be a suitable location to construct a seabed water filter as a replacement for the current open water intake. The Om Almisk Island site was evaluated through collection of sand samples over a radial grid around Om Almisk Island and sample analysis using grain size distribution, porosity, and hydraulic conductivity. The lack of mud, high hydraulic conductivity, proximity to KAUST, and the shallow waters of the sandy apron surrounding Om Almisk Island make this an ideal location for a seabed water filter to be used as an intake and pretreatment for the KAUST desalination plant. This location also has low tide change and the presence of benthic macrofauna to create bioturbation in the sediments, which could inhibit the growth of a schmutzdecke. If this biological layer forms, it could drastically reduce the hydraulic conductivity of the system. Due to the high hydraulic

    The state of the art in biodiversity data management unfortunately encompases a plethora of diverse data formats. Compared to other research fields, there is a lack in harmonization and standardization of these data. While data from traditional biodiversity collections (e.g. from museums) can be easily represented by existing standard as provided by TDWG, the growing number of field observations stemming from both VGI activities (e.g. iNaturalist) as well as from automated systems (e.g. animal biotelemetry) would at the very least require upgrades of current formats. Moreover, from an eco-informatics perspective, the integration and use of data from different scientific fields is the norm (abiotic data, geographic information, etc.); the possibility to represent this information and biodiversity data in a homogeneous way would be an advantage for interoperability, allowing for easy integration across environmental media. We will discuss the possibility to exploit the Open Geospatial Consortium/ISO standard, Observations and Measurements (O&M) [1], a generic conceptual model developed for observation data but with strong analogies with the biodiversity-oriented OBOE ontology [2]. The applicability of OGC O&M for the provision of biodiviersity occurence data has been suggested by the INSPIRE Cross Thematic Working Group on Observations & Measurements [3], Inspire Environmental Monitoring Facilities Thematic Working Group [4] and New Zealand Environmental Information Interoperability Framework [5]. This approach, in our opinion, could be an advantage for the biodiversity community. We will provide some examples for encoding biodiversity occurence data using the O&M standard in addition to highlighting the advatages offered by O&M in comparison to other representation formats.

  19. OM and A considerations in PLEx decision making for CANDUR reactors

    In recent years, owners and operators of mature nuclear plants that are reaching their design life, are contemplating Plant Life Extension (PLEx) to continue generating low cost electricity. While the business case for PLEx is typically organized along the immediate investment requirements to carryout the planned refurbishment of the plant components, a similar level of attention and focus should be placed on the post refurbishment OM and A costs of the plant. If the refurbishment is based on a one-to-one replacement of aging or non-repairable components, then post refurbishment OM and A costs can be expected to be similar to those before refurbishment. This paper presents supporting arguments to align post-refurbishment OM and A, with certain modifications to the plant during refurbishment, which can yield a significantly reduced OM and A costs over the extended life. The paper describes techniques, which are being investigated for operating CANDU R plants, the will reduce the overall manpower requirements through more automation applied to testing, analyses, equipment status monitoring, regulatory surveillance/reporting etc., and integration of plant information systems. Application of Condition Based Monitoring combined with Reliability Centred Maintenance will minimize operational maintenance intervention and action, and hence, further reduce the maintenance manpower resources. These examples will be applied to two typical CANDU R situations - one using PLEx as the example (Point Lepreau Station) and the other using plant restart of laid up units (Pickering A Station) to illustrate these concepts. Specific data for these two plant types will be described with and without implementation of the OM and A reduction techniques described above to demonstrate potential manpower reductions. The paper will also describe how the Canadian nuclear industry has been able to deal with the lack of trained personnel and turn things around; and is in a position to start up the

    Innovative americium-bearing uranium-plutonium mixed oxides U1-yPuyO2-x are envisioned as nuclear fuel for sodium-cooled fast neutron reactors (SFRs). The oxygen-to-metal (O/M) ratio, directly related to the oxidation state of cations, affects many of the fuel properties. Thus, a thorough knowledge of its variation with the sintering conditions is essential. The aim of this work is to follow the oxidation state of uranium, plutonium, and americium, and so the O/M ratio, in U0.750Pu0.246Am0.004O2-x samples sintered for 4 h at 2023 K in various Ar + 5% H2 + z vpm H2O (z = ∼ 15, ∼ 90, and ∼ 200) gas mixtures. The O/M ratios were determined by gravimetry, XAS, and XRD and evidenced a partial oxidation of the samples at room temperature. Finally, by comparing XANES and EXAFS results to that of a previous study, we demonstrate that the presence of uranium does not influence the interactions between americium and plutonium and that the differences in the O/M ratio between the investigated conditions is controlled by the reduction of plutonium. We also discuss the role of the homogeneity of cation distribution, as determined by EPMA, on the mechanisms involved in the reduction process.

    1983-01-01

    Investigation of Space Transportation System (STS) Atmospheric Luminosities (ISAL) experiment documentation includes vertical tail and orbital maneuvering system (OMS) pods with surface glow against the blackness of space. This glowing scene was provided by a long duration exposure with a 35mm camera aimed toward the tail of the Earth-orbiting Challenger, Orbiter Vehicle (OV) 099. OV-099 was maneuvered to a 120-nautical-mile altitude and flown with open payload bay (PLB) in the velocity vector for the conducting of a test titled, 'Evaluation of Oxygen Interaction with Materials (EOIM)'. Atomic oxygen within the low orbital environment is known to be extremely reactive when in contact with solid surfaces. In the darkened area between the camera and the glowing OMS pods and vertical stabilizer are two trays of test materials.

    2015-04-01

    Full Text Available Jeg presenterer her en analyse og tolkning av Herbarts syn på oppdragelse og danning, med feste i to av hans begreper: formbarhet – Bildsamkeit – og takt. Det første kaster lys over forholdet mellom lærer og elev, det andre først og fremst over forholdet mellom teori og praksis. For ham, som for forgjengeren Immanuel Kant, dreiet det seg om subjektivitet og frihet, eller mer konkret: Hvordan oppdra til autonomi der det også kreves tvang? Så vidt jeg kan se, bruker Herbart de to grunnbegrepene nettopp til å bestemme det paradoksale og uferdige forholdet mellom frihet og tvang. Han forklarer det som et åpent forhold eller relasjon som ikke har en bestemt begynnelse og heller ikke en bestemt konklusjon. Verken tradisjon eller vitenskap kan ved seg selv realisere dette råderommet. Han tenker seg et frirom der kunnskap, intuisjon og skjønn spiller på lag i oppdragelsen. Tradisjonen henger gjerne igjen i gamle fordommer, vitenskapen fanges i teori og abstrakt skjema, og ingen av dem dekker de unike situasjonene som nyskaper forholdet mellom voksne og barn. Herbart stilte seg åpen til spørsmål som ikke løses ved styring og kontroll, og spør implisitt om ikke vi også kan gjøre det samme.

    In order to determine the dose responsiveness to radiation of ocular melanoma, we conducted an in vitro dose-response study on a monolayer cell culture using a clonogenic assay. The effects on cell survival were determined relative to unirradiated controls. A human epithelioid ocular melanoma cell line, OM431, was maintained in tissue culture and serial dilutions of viable cells were plated in flasks, allowed to settle and attach for 48 h, and subsequently irradiated with 1-10 Gy in single fractions. After 2 weeks, the number of reproducing clones (forming colonies with greater than 32 cells or five generations) were counted. The surviving fractions of cells were plotted on a cell survival curve using the linear quadratic model. The survival curve showed a large initial shoulder followed by an exponential decline in growth. Our data suggest that the OM431 ocular melanoma cell line responds to irradiation in a manner similar to other melanoma cell lines and is relatively radioresistent especially at lower doses.

    A new and facile route is reported to manipulate the self-assembly synthesis of hierarchically ordered Rb-OMS-2 and pyrolusite with an interesting flowerlike morphology by a direct and mild reaction between rubidium chromateand manganese sulfate without any organic templates. The crystal forms, morphologies, and tunnel sizes of the obtained OMS materials can be controlled. A mechanism for the growth of manganese dioxides with flowerlike architectures was proposed. The obtained products exhibit potential for use in catalysis and other applications.

    To investigate the impact of waiting for psychological therapy on client well-being as measured by the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) global distress (GD) score. Global distress scores were retrieved for all clients referred for psychological therapy in a secondary care mental health service between November 2006 and May 2013 and who had completed a CORE-OM at assessment and first session. GD scores for a subgroup of 103 clients who had completed a CORE-OM during the last therapy session were also reviewed. The study sample experienced a median wait of 41.14 weeks between assessment and first session. The relationship between wait time from referral acceptance to assessment, and assessment GD score was not significant. During the period between assessment and first session no significant difference in GD score was observed. Nevertheless 29.1% of the sample experienced reliable change; 16.0% of clients reliably improved and 13.1% reliably deteriorated whilst waiting for therapy. Demographic factors were not found to have a significant effect on the change in GD score between assessment and first session. Waiting time was associated with post-therapy outcomes but not to a degree which was meaningful. The majority of individuals (54.4%), regardless of whether they improved or deteriorated whilst waiting for therapy, showed reliable improvement at end of therapy as measured by the CORE-OM. The majority of GD scores remained stable while waiting for therapy; however, 29.1% of secondary care clients experienced either reliable improvement or deterioration. Irrespective of whether they improved, deteriorated or remained unchanged whilst waiting for therapy, most individuals who had a complete end of therapy assessment showed reliable improvements following therapy. There was no significant difference in GD score between assessment and first session recordings. A proportion of clients (29.1%) showed reliable change, either improvement or

    2010-01-01

    This paper presents the results of survey performed to find out how occupational medicine service (OMS) nurses assess their tasks and roles in the Polish system of workers' health protection. The survey was carried out in a random group of 200 OMS nurses. The survey showed that OMS nurses form-an experienced professional group. According to self-assessment they have an opportunity to use their competence in its full scope. Almost half of respondents agreed that in Poland the skills of OMS nurses are properly used. There are two reasons why certain tasks are not performed by OMS nurses, first, certain tasks are assigned to other persons in the unit; second, employers are sometimes not interested in those tasks or find them not necessary. The majority of nurses assess their knowledge and preparation to perform tasks relatively well, however they want to broaden their knowledge and improve their skills. OMS nurses play an important role in the Polish system of workers' health protection. They perform many tasks, which fall within the scope of OMS activities being currently implemented. Their competences are usually properly used. There is a need to convince employers that the scope of services provided by OMS units should be extended and adequately financed. This should result in the better use of OMS nurses' competences. Nurses are well educated and skilled to perform their jobs. Nevertheless, they feel the need to broaden their knowledge. Although the programs of specialization and qualification courses are rather comprehensive, nurses declare that some areas should be enriched with additional information.

    1996-12-01

    In the second half of the decade of the nineties, the imperative of finding new ways to improve efficiency while maintaining safety is taking on a new urgency. The looming deregulation of the electric industry and the expected competition in the power production business fuels this urgency. The recently completed ASME research in the area of Risk-Based Inservice Testing offers the Operations and Maintenance (O&M) Committee an opportunity to meet this challenge. This opportunity, however, offers its own challenges. New ways of thinking about inservice testing and new technical skills will be needed to successfully incorporate this technology into Code documents. It will not be adequate to rely solely on incorporation of risk-based methods into the Code to meet this challenge. A thorough self assessment of what O&M does, how it is done, and the value added will help assure that the directions which are pursued do, indeed, meet the challenge ahead.

    This study explores the emergence of OM, the Sanskrit mantra and critically ubiquitous "sacred syllable" of South Asian religions. Although OM has remained in active practice in recitation, ritual, and meditation for the last three thousand years, and its importance in Hindu, Buddhist, and Jain traditions is widely acknowledged, the syllable's early development has received little attention from scholars. Drawing on the oldest textual corpus in South Asia, the Vedas, I survey one thousand yea...

    A magnetic route has been applied for measurement of the average oxidation state (AOS) of mixed-valent manganese in manganese oxide octahedral molecular sieves (OMS). The method gives AOS measurement results in good agreement with titration methods. A maximum analysis deviation error of +/-7% is obtained from 10 sample measurements. The magnetic method is able to (1) confirm the presence of mixed-valent manganese and (2) evaluate AOS and the spin states of d electrons of both single oxidation state and mixed-valent state Mn in manganese oxides. In addition, the magnetic method may be extended to (1) determine AOS of Mn in manganese oxide OMS with dopant "diamagnetic" ions, such as reducible V5+ (3d0) ions, which is inappropriate for the titration method due to interference of redox reactions between these dopant ions and titration reagents, such as KMnO4, (2) evaluate the dopant "paramagnetic" ions that are present as clusters or in the OMS framework, and (3) determine AOS of other mixed-valent/single oxidation state ion systems, such as Mo3+(3d3)-Mo4+(3d2) systems and Fe3+ in FeCl3.

  17. Warm Paleocene/Eocene climate as simulated in ECHAM5/MPI-OM

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available We investigate the late Paleocene/early Eocene (PE climate using the coupled atmosphere-ocean-sea ice model ECHAM5/MPI-OM. The surface in our PE control simulation is on average 297 K warm and ice-free, despite a moderate atmospheric CO2 concentration of 560 ppm. Compared to a pre-industrial reference simulation (PR, low latitudes are 5 to 8 K warmer, while high latitudes are up to 40 K warmer. This high-latitude amplification is in line with proxy data, yet a comparison to sea surface temperature proxy data suggests that the Arctic surface temperatures are still too low in our PE simulation.

    To identify the mechanisms that cause the PE-PR surface temperature differences, we fit two simple energy balance models to the ECHAM5/MPI-OM results. We find that about 2/3 of the PE-PR global mean surface temperature difference are caused by a smaller clear sky emissivity due to higher atmospheric CO2 and water vapour concentrations in PE compared to PR; 1/3 is due to a smaller planetary albedo. The reduction of the pole-to-equator temperature gradient in PE compared to PR is due to (1 the large high-latitude effect of the higher CO2 and water vapour concentrations in PE compared to PR, (2 the lower Antarctic orography, (3 the smaller surface albedo at high latitudes, and (4 longwave cloud radiative effects. Our results support the hypothesis that local radiative effects rather than increased meridional heat transports were responsible for the "equable" PE climate.

  18. O/M ratio measurement in pure and mixed oxide fuels - where are we now?

    The scale-down in the US and Russian nuclear weapons stockpiles has produced a surplus of weapons grade plutonium and highly enriched uranium. The incorporation into mixed-oxide fuel (MOX) is one of the currently favored routes for surplus weapons-grade plutonium. The use of MOX as a nuclear reactor fuel is well established, particularly in Europe and Japan but not in the US. The primary purpose of this investigation was to evaluate existing analytical techniques for their applicability to O/M (oxygen-to-metal ratio) measurements of MOX derived from excess weapons plutonium. The second objective of this investigation was to bring up-to-date the literature on O/M measurement methods, which has not been undertaken in over 20 years. There are several classification schemes that can be used to organize O/M measurement methods. The most popular schemes are based on (a) whether the analysis is performed in solution (wet chemical) or on solid material (dry), and (b) whether the concentration of major constituents are analyzed directly (direct) or are inferred (indirect). Solid state coulometric titration is currently used extensively in studies of phase equilibria, defect chemistry, thermochemical measurement of oxides, including ferrites. Regardless of which indirect method is used (solid state coulometric titration or thermogravimetry), a primary, direct method will also be required for the establishment of the MO{sub 2} reference state, determination of method bias, and periodic calibration. It was recommended that the following direct method be adapted for this purpose: oxygen measurement by inert gas fusion/carbon reduction, and total U, Pu by controlled potential coulometry. In a table are listed the experimental values of accuracy for about 30 O/M methods. (A.C.)

    Porous FeVO 4 is prepared by hydrothermal method and further modified by coating with carbon to obtain FeVO 4 /C with a hierarchical pore structure. FeVO 4 /C is used as an anodic electrode in aqueous rechargeable magnesium-ion batteries. The FeVO 4 /C material not only has improved electrical conductivity as a result of the carbon coating layer, but also has an increased specific surface area as a result of the hierarchical pore structure, which is beneficial for magnesium-ion insertion/deinsertion. Therefore, an aqueous rechargeable magnesium-ion full battery is successfully constructed with FeVO 4 /C as the anode, Mg-OMS-1 (OMS=octahedral molecular sieves) as the cathode, and 1.0 mol L -1 MgSO 4 as the electrolyte. The discharge capacity of the Mg-OMS-1//FeVO 4 /C aqueous battery is 58.9 mAh g -1 at a current density of 100 mA g -1 ; this value is obtained by calculating the total mass of two electrodes and the capacity retention rate of this device is 97.7 % after 100 cycles, with almost 100 % coulombic efficiency, which indicates that the system has a good electrochemical reversibility. Additionally, this system can achieve a high energy density of 70.4 Wh kg -1 , which provides powerful evidence that an aqueous magnesium-ion battery is possible. © 2017 Wiley-VCH Verlag GmbH & Co.

    1997-01-01

    An evaluation test to investigate the behavior of the Oxygen to Metal ratio (O/M ratio) drift and its effect to material accounting in Feed preparation process was carried out in operational MOX fuel fabrication process, Plutonium Fuel Production Facility (PFPF) of Power Reactor and Nuclear Fuel Development Corporation (PNC). The test results clearly show the transition of O/M ratio along the Feed preparation process flow and it was increased gradually according to the progress of process steps. It leveled off after Feed lot blending operation and then it remained stable around 2.25. Analytical result of plutonium concentration after the correction with the changes of moisture concentration on the same sample as O/M ratio analysis has strong correlation with O/M ratio result as the theory. Therefore, it was confirmed that the plutonium concentration of the MOX should be corrected on the basis of the changes in O/M ratio and moisture concentration. Sample taking after blending operation was carried out at Cross Blending process step. An analysis of variance for plutonium concentration using two-way layout, whose factors are feed blending batch (factor A) and container (factor B), is carried out. Since no significant difference was observed in factor A nor B, the test concludes that a sample taken after blending operation can be considered as representative for the whole material blended by cross blending operation. Now the software of 'Material Accounting System' is being modified to improved one, that is, the plutonium concentration after the intermediate storage and after treatment in a process glove box is corrected with the change of O/M ratio and moisture concentration.

    Full Text Available La dernière édition des Apports nutritionnels conseillés (ANC- éd. 2001 souligne la nécessité d’accroître la consommation d’acide alpha-linolénique (ALA. Celle-ci devrait au minimum doubler et représenter 0,8 % (par rapport à l’énergie totale contre 0,34 % actuellement. Or, l’étude Aquitaine [1] a montré que les lipides d’origine animale contribuaient à près de 75 % de l’apport alimentaire en ALA. Ainsi, parmi les stratégies envisageables pour accroître notre consommation d’ALA, sans changer fondamentalement les habitudes alimentaires des Français, on note un intérêt croissant pour augmenter la teneur en oméga 3 des produits animaux via l’alimentation de ces derniers. Quelques exemples de modification de la composition en acides gras des produits animaux sont exposés. Chez les espèces monogastriques (volaille, porc, le profil des lipides de carcasse est un bon reflet des lipides alimentaires. Ainsi, chez le porc, le niveau d’oméga 3 peut être augmenté d’un facteur 2 à 4, lorsque les animaux reçoivent dans leur alimentation de l’huile de colza, des graines de lin ou de la farine de poissons. En revanche, chez les animaux ruminants, le transfert des acides gras polyinsaturés alimentaires vers les tissus est faible en raison de l’hydrogénation qu’ils subissent dans le rumen. Certaines stratégies qui consistent à protéger ces acides gras de la biohydrogénation permettent néanmoins d’accroître le taux d’ALA dans les tissus et le lait. Ainsi, il apparaît possible d’augmenter la consommation d’oméga 3 de la population, via la consommation de produits issus d’animaux nourris avec des sources d’oméga 3. Cependant, au niveau de la production, ces changements doivent être maîtrisés \\; ils ne peuvent se faire sans un contrôle des qualités d’une part organoleptiques, en raison du degré élevé d’oxydabilité de ces acides gras, d’autre part de texture, en raison

    We show that a four-parameter class of 3+1 dimensional NCOS theories can be obtained by dimensional reduction on a general 2-torus from OM theory. Compactifying two spatial directions of NCOS theory on a 2-torus, we study the transformation properties under the SO(2,2; Z) T-duality group. We then discuss non-perturbative configurations of non-commutative super Yang-Mills theory. In particular, we calculate the tension for magnetic monopoles and (p,q) dyons and exhibit their six-dimensional origin, and construct a supergravity solution representing an instanton in the gauge theory. We also compute the potential for a monopole-antimonopole in the supergravity approximation. (author)

    Flow cytometric cerebrospinal fluid (CSF) lymphocyte subset analysis has improved the diagnosis of neuroinflammation and identified multiple markers of inflammation in opsoclonus-myoclonus syndrome (OMS). The aim of this exploratory, retrospective study was to analyze the effect of immunotherapy on these markers to determine which agents are disease modifying. Cross-sectional immunological observations were made in an IRB-approved case-control study, and patients were treated empirically. Ten different CSF lymphocyte subpopulations from 18 children with persistent OMS had been measured by flow cytometry before and after clinical treatment with cyclophosphamide/ACTH/IVIG combination (n = 7) or ACTH/IVIG alone (n = 11). Clinical severity of OMS was scored from videotapes by a blinded observer using the OMS Evaluation Scale. Only cyclophosphamide combination therapy (mean dose 26 ± 3 mg/kg or 922 ± 176 mg/m 2 x 6 cycles) significantly decreased the percentage of CSF B cells. The mean reduction was 65%, with CSF B cell frequency normalized at 7-8 months in 70%. Other abnormalities of the CSF immunophenotype, such as the low CD4/CD8 T cell ratio, persisted, and there were no therapeutic changes in T cell activation/maturation markers. Effects on relative and absolute size of PBMC subsets were similar. Clinical improvement was 70% and 55% in respective treatment groups. The relapse rates of the two groups did not significantly differ. The main effect of cyclophosphamide combination therapy on neuroinflammation in OMS was moderate reduction in CSF B cell expansion. Though exploratory, it may provide a steroid sparer option in partially-responsive OMS. Copyright © 2018 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

  9. Seasonal and spatial variability of the OM/OC mass ratios and high regional correlation between oxalic acid and zinc in Chinese urban organic aerosols

    2013-04-01

    Full Text Available We calculated the organic matter to organic carbon mass ratios (OM/OC mass ratios in PM2.5 collected from 14 Chinese cities during summer and winter of 2003 and analyzed the causes for their seasonal and spatial variability. The OM/OC mass ratios were calculated two ways. Using a mass balance method, the calculated OM/OC mass ratios averaged 1.92 ± 0.39 year-round, with no significant seasonal or spatial variation. The second calculation was based on chemical species analyses of the organic compounds extracted from the PM2.5 samples using dichloromethane/methanol and water. The calculated OM/OC mass ratio in summer was relatively high (1.75 ± 0.13 and spatially-invariant due to vigorous photochemistry and secondary organic aerosol (OA production throughout the country. The calculated OM/OC mass ratio in winter (1.59 ± 0.18 was significantly lower than that in summer, with lower values in northern cities (1.51 ± 0.07 than in southern cities (1.65 ± 0.15. This likely reflects the wider usage of coal for heating purposes in northern China in winter, in contrast to the larger contributions from biofuel and biomass burning in southern China in winter. On average, organic matter constituted 36% and 34% of Chinese urban PM2.5 mass in summer and winter, respectively. We report, for the first time, a high regional correlation between Zn and oxalic acid in Chinese urban aerosols in summer. This is consistent with the formation of stable Zn oxalate complex in the aerosol phase previously proposed by Furukawa and Takahashi (2011. We found that many other dicarboxylic acids were also highly correlated with Zn in the summer Chinese urban aerosol samples, suggesting that they may also form stable organic complexes with Zn. Such formation may have profound implications for the atmospheric abundance and hygroscopic properties of aerosol dicarboxylic acids.

    Lipids A, the lipophilic partial structure of lipopolysaccharides, induce regression of several tumor types in animal models. Rather than exerting direct cytotoxic effect, these compounds trigger the immune system which in turn stimulates secretion of cytokines, and activates the inducible nitric oxide synthase, as well as immune cell infiltration of tumors. OM-174 is an analogue of lipid A with dual action on Toll-like receptors 2 and 4. In an experimental model of peritoneal carcinomatosis induced in BDIX rats by intraperitoneal injection of syngeneic PROb colon cancer cells, it induced a complete regression of tumors. The present phase I trial was conducted to determine the maximum tolerated dose, the recommended phase II dose and biological response associated with OM-174 administered as intravenous infusion. Patients received OM-174 twice weekly for a total of 5, 10 or 15 injections of either 600, 800 or 1000 μg/m 2 . Blood samples for pharmacokinetic analysis and cytokine dosages were collected. NK cells activity and Toll-like receptors 4 polymorphism analysis were also performed. Seventeen patients were included. The highest dose administered was 1000 μg/m 2 repeated in 15 injections. The most common toxicities were a chills, fever, nausea/vomiting, diarrhea, fatigue and headache. No patient experienced haematological side effects. As no dose limiting toxicity was observed, despite a grade 3 respiratory complication, the maximal tolerated dose and recommended dose were not established. Three patients exhibited disease stabilization with a mean duration of 4 months. Pharmacokinetic profile of OM-174 was characterized by a low distribution volume and clearance. Analysis of TLR 4 polymorphysm showed that most (16/17) patients carried the wild type alleles. A progressive increase in NK cell number and activity was observed only in patients receiving 1000 μg/m 2 of OM-174. A peak of IL-8 and IL-10 concentrations were observed after each OM-174 injection.

  15. The behaviour of zirconium alloys in Santowax OM organic coolant at high temperatures

    1964-10-01

    Zirconium alloys have been exposed to Santowax OM at temperatures of 320 to 400 o C for times as long as 5000 hours. Short-term experiments (less than 2 weeks) were done in stainless-steel bombs and small out-of-pile loops. The X-7 organic loop in the NRX reactor was used to study long-term oxidation and hydriding both in-flux and out-of-flux. The results obtained lead to several tentative conclusions: Aluminum cladding serves as an effective hydrogen barrier; Considerable protection against hydriding is given by zirconium oxide, provided impurities in the organic are carefully controlled; Hydriding is greatly enhanced by the presence of chlorine in the coolant; and, Hydriding is somewhat enhanced by neutron irradiation. Of considerable significance is the fact that a Zircaloy-4 in-reactor test section of the X-7 loop was exposed to Santowax OM at 320 to 400 o C for more than 5000 hours without excessive hydriding.

  3. Membrane Fouling Potential of Secondary Effluent Organic Matter (EfOM) from Conventional Activated Sludge Process

    KAUST Repository

    Wei, Chunhai; Amy, Gary L.

    2012-01-01

    Secondary effluent organic matter (EfOM) from a conventional activated sludge process was filtered through constant-pressure dead-end filtration tests with a sequential ultrafiltration (UF, molecular weight cut-off (MWCO) of 10k Dalton) and nanofiltration (NF, MWCO of 200 Dalton) array to investigate its membrane fouling potential. Advanced analytical methods including liquid chromatography with online carbon detection (LC-OCD) and fluorescent excitation-emission matrix (F-EEM) were employed for EfOM characterization. EfOM consisted of humic substances and building blocks, low molecular weight (LMW) neutrals, biopolymers (mainly proteins) and hydrophobic organics according to the sequence of their organic carbon fractions. The UF rejected only biopolymers and the NF rejected most humics and building blocks and a significant part of LMW neutrals. Simultaneous occurrence of cake layer and standard blocking during the filtration process of both UF and NF was identified according to constant-pressure filtration equations, which was possibly caused by the heterogeneous nature of EfOM with a wide MW distribution (several ten to several million Dalton). Thus the corresponding two fouling indices (kc for cake layer and ks for standard blocking) from UF and NF could characterize the fouling potential of macromolecular biopolymers and low to intermediate MW organics (including humics, building blocks, LMW neutrals), respectively. Compared with macromolecular biopolymers, low to intermediate MW organics exhibited a much higher fouling potential due to their lower molecular weight and higher concentration.

    Thermogravimetric studies were carried out in unsintered and sintered samples of uranium oxide, plutonium oxide and uranium-plutonium mixed oxide under different atmospheric conditions (air, argon and moist argon/hydrogen). Moisture loss was found to occur below 200 0 C for uranium dioxide samples, upto 700 0 C for sintered plutonium dioxide and negligible for sintered samples. The O/M ratios for non-stoichiometric uranium dioxide (sintered and unsintered), plutonium dioxide and mixed uranium and plutonium oxides (sintered) could be obtained with a precision of +- 0.002. Two reference states UOsub(2.000) and UOsub(2.656) were obtained for uranium dioxide and the reference state MOsub(2.000) was used for other cases. For unsintered plutonium dioxide samples, accurate O/M ratios could not be obtained of overlap of moisture loss with oxygen loss/gain. (author)

    Measurements of artificial plasma turbulence were obtained during two Shuttle Exhaust Ionospheric Turbulence Experiments (SEITE) conducted during the flights of the Space Shuttle (STS-127 and STS-129). Based on computer modeling at the NRL PPD and Laboratory for Computational Physics & Fluid Dynamics (LCP), two dedicated burns of the Space Shuttle Orbital Maneuver Subsystem (OMS) engines were scheduled to produce 200 to 240 kg exhaust clouds that passed over the Air Force Research Laboratory (AFRL) Communications, Navigation, and Outage Forecast System (C/NOFS) satellite. This operation required the coordination by the DoD Space Test Program (STP), the NASA Flight Dynamics Officer (FDO), the C/NOFS payload operations, and the C/NOFS instrument principal investigators. The first SEITE mission used exhaust from a 12 Second OMS burn to deposit 1 Giga-Joules of energy into the upper atmosphere at a range of 230 km from C/NOFS. The burn was timed so C/NOFS could fly though the center of the exhaust cloud at a range of 87 km above the orbit of the Space Shuttle. The first SEITE experiment is important because is provided plume detection by ionospheric plasma and electric field probes for direct sampling of irregularities that can scatter radar signals. Three types of waves were detected by C/NOFS during and after the first SEITE burn. With the ignition and termination of the pair of OMS engines, whistler mode signals were recorded at C/NOFS. Six seconds after ignition, a large amplitude electromagnetic pulse reached the satellite. This has been identified as a fast magnetosonic wave propagating across magnetic field lines to reach the electric field (VEFI) sensors on the satellite. Thirty seconds after the burn, the exhaust cloud reach C/NOFS and engulfed the satellite providing very strong electric field turbulence along with enhancements in electron and ion densities. Kinetic modeling has been used to track the electric field turbulence to an unstable velocity

The lines of the scheme, their lengths, and their intersections, determine the articulation of the Borobudur composition, i. e. the sizes of every part and of the whole as well. The sizes of Borobudur are modular. Their modular multiples are Pell numbers, the ratios of which rationally approximate the irrational proportions in octagram  If Borobudur numbers are located in the Peli number-pattern and connected with a line, the syllable OM, written in Sanskrit, appears. The word octagram is only the modern European name of the symbol of OM. The prayer OM MANI PADME HUM, translated as 'the JEWEL and the LOTOS', is a good description of octagram.

    Full Text Available A village-scale trial of organochlorin compound OMS-1558 as an 70% water-dispersible powder (wdp and applied as an indoor residual spray at 2 gr/m2, was carried out against the DDT—resistant malaria vector Anopheles aconitus near Semarang, Central Java. Result of this trial, as evaluated by human-vector contact rates, resting densities and parous rate showed effectiveness against the vector populations for only about one week or less. In contact bioassay tests mortalities of 50% or greater for one week, while mortalities from air-borne bioassay tests were negligible. It was concluded that DDT—resistant malaria vector can not be controlled by this insecticide. The result of susceptibility tests showed there is cross resistance between DDT and new organochlorin OMS-1558.

  2. Improving interpretation of infrared spectra for OM characterization by subtraction of spectra from incinerated samples

    Science.gov (United States)

    Ellerbrock, Ruth H.; Gerke, Horst H.; Leue, Martin

    2017-04-01

    Non-destructive methods such as diffuse reflectance infrared Fourier transform spectroscopy (DRIFT) have been applied to characterize organic matter (OM) at intact structural surfaces among others. However, it is often difficult to distinguish effects of organic components on DRIFT signal intensities from those of mineral components. The objective of this study was to re-evaluate DRIFT spectra from intact earthworm burrow walls and coated cracks to improve the interpretation of C-H and C=O bands. We compared DRIFT and transmission Fourier transform infrared (FTIR) spectra of entire samples that were from the same pedogenetic soil horizon, but different in mineral composition and texture (i.e., glacial till versus loess). Spectra of incinerated samples were subtracted from the original spectra. Transmission FTIR and DRIFT spectra were almost identical for entire soil samples. However, the DRIFT spectra were affected by the bulk mode bands (i.e., wavenumbers 2000 to 1700 cm-1) that affected spectral resolution and reproducibility. The ratios between C-H and C=O band intensities as indicator for OM quality obtained with DRIFT were smaller than those obtained from transmission FTIR. A spectral subtraction procedure was found to reduce effects of mineral absorption bands on DRIFT spectra allowing an improved interpretation. DRIFT spectroscopy as a non-destructive method for analyzing OM composition at intact surfaces in structured soils could be calibrated with information obtained with the more detailed transmission FTIR and complementary methods.

    2010-01-01

    Full Text Available En relativ stor andel av befolkningen i yrkesaktiv alder i de nordiske landene mottar uførepensjon, og i Norge er det en klar tendens til økning. Parallelt med dette har interessen for forskning rundt uførepensjon som fenomen økt. Vi har i denne studien beskrevet den epidemiologiske forskningen om uførepensjon i Norden. I en systematisk litteraturgjennomgang fant vi 118 aktuelle artikler. Alle de nordiske landene er godt representert. Kohortstudier med uførepensjon som endepunkt utgjorde hovedvekten av materialet, hvor 67 var populasjonsbaserte mens 29 tok utgangspunkt i selekterte pasientpopulasjoner. I alt seks kohortstudier benyttet uførepensjon som eksponering. Vi fant videre syv kasus-kontrollstudier og ni forsøk. Det er betydelig dokumentasjon på at ulike sykdommer og helseplager er assosiert med økt risiko for uførhet, i tillegg til at sosioøkonomiske og arbeidsrelaterte forhold er av betydning. Gjennomgangen viser at den epidemiologiske forskningen for det meste har rettet blikket mot individuelle årsaker til uførepensjonering. Selv om denne forskningen er viktig, kan den neppe forklare økningen vi har sett i det siste tiåret. Den videre forskningen bør utforske nærmere hvordan individuell sårbarhet ender i utstøtelse fra arbeidslivet. Med tanke på den omfattende forskningen om årsaker på dette feltet, bør man også i større grad gjennomføre forsøk for å bedre utsatte gruppers arbeidsdeltakelse.Bjørngaard JH, Krokstad S, Johnsen R, Karlsen AO, Pape K, Støver M, Sund E, Westin S.

    To study the role of Th2-attracting chemokines in opsoclonus-myoclonus syndrome (OMS), a serious neurological paraneoplastic disorder in need of better immunological understanding and therapy. The CCR4 agonists CCL22 and CCL17 were measured in serum by ELISA in children with OMS (238 and 260, respectively), pediatric controls (115 and 143), and other inflammatory neurological disorders (33 and 24). Both CCL22 (+55 %) and CCL17 (+121 %) were significantly elevated in untreated OMS compared to controls and inter-correlated (p OMS also were higher than in OIND (21 %, 41 %). The concentration of CCL22 in ACTH and steroids groups (not IVIg) was 51 % lower than in controls, but only a smaller effect of ACTH on CCL17 was found. Prospective longitudinal studies revealed a precipitous 81 % drop in CCL22 even by the first week of high-dose ACTH therapy, staying below control mean for at least 12 weeks, and a 34 % reduction after 8 months of combined treatment. Response to ACTH was dose-related (r = -0.50, p OMS. Marked and rapid reduction in CCL22, not CCL17, with either ACTH or steroid therapy suggests differential regulation and cellular sources of CCR4 ligands, and CCL22 as a potential candidate biomarker for ACTH or corticosteroid effect.

  19. Synthesis and characterization of novel mesocomposites Co3O4 and CuO@OMS (ordered mesoporous silica) as active catalysts for hydrocarbon oxidation

    Science.gov (United States)

    Comănescu, Cezar

    2014-03-01

    Novel metal nanoporous transition metal oxides M x O y (Co3O4, CuO) have been synthesized by thermal decomposition of inorganic salts precursors (acetates, nitrates) impregnated into hexagonal mesoporous silica (OMS, ordered mesoporous silica) of SBA-15 type (prepared in-house) at different precursor loadings, the mesocomposites thus obtained being monitored after each impregnation-calcination step by small and wide angle powder XRD. The pore size for the ordered silica host range from 5.08 to 7.06 nm. Retention of the hexagonal silica framework has been observed in spite of the temperatures up to 500 °C. Mesoporous Co3O4 has been obtained by leaching the silica through overnight HF dissolution, which partially preserved the small-range ordering found in the parent Co3O4@OMS composite prior to leaching. Both Co3O4 ( meso) and Co3O4@SBA-15 have been tested in methane oxidation and were found to be superior to the bulk Co3O4 performance, with mesoporous Co3O4 being able to fully oxidize methane to CO2 and H2O at 350 °C, while Co3O4@OMS exhibits a lower activity with 20 % conversion at 350 °C. CuO@OMS shows the lowest activity, with only 13 % conversion at 500 °C.

  20. Investigation on pseudosymmetry, twinning and disorder in crystal structure determinations: Ba(H2O)M2III[PO3(OH)]4 (M=Fe, V) as examples

    Twinning commonly occurs in monoclinic crystals with dimensionally similar a and c axes and results in pseudo-orthorhombic symmetries with overlapping diffractions. For example, twinning in the new synthetic compound Ba(H 2 O)Fe 2 [PO 3 (OH)] 4 , which varies in space group from P2 1 to P2 1 /c with approximately equal a and c axial lengths, gives rise to a pseudosymmetry of C222 1 . Similarly, the related compound Ba(H 2 O)V 2 [PO 3 (OH)] 4 is commonly twinned and varies in space groups as well, arising from ordered to disordered distributions of the barium cations and water molecules in the cavities. Moreover, analyses of these and other twinned structures show that the small average standard uncertainty of bond distances is a sensitive criterion for structure determinations, especially for those involving crystal twinning as well as order–disorder. A proper structure determination leads to small standard uncertainties of the atomic displacement parameters, which further result in the small standard uncertainties of bond distances. - Graphical abstract: Ba(H 2 O)M 2 III [PO 3 (OH)] 4 (M=Fe, V) varies in space group from P2 1 to P2 1 /c, arising from ordered to disordered distributions of Ba 2+ and H 2 O in the cavities. Highlights: ► Twinning commonly occurs in monoclinic crystals with a≈c. ► Overlapping diffractions from twin domains hamper with the determination of real space groups. ► Conventional criteria for evaluating the real space groups are not effective in this case. ► Small standard uncertainty of bond distances is proposed as a sensitive criterion. ► Using this criterion we determined the order–disorder structures of Ba(H 2 O)M 2 III [PO 3 (OH)] 4 (M=Fe, V) from twinned crystals.

    Filloux, Emmanuelle

    2012-08-01

    Five secondary effluents and a river water source were characterized using size exclusion chromatography (LC-OCD-UVD-OND) and emission-excitation matrix (EEM) fluorescence spectroscopy in order to identify the major effluent organic matter (EfOM) fractions responsible for membrane fouling. This study showed the feasibility of coupling fluorescence EEM and LC-OCD-UVD-OND to investigate the fouling potential as well as a means to differentiate natural organic matter (NOM) from EfOM. The secondary effluents and river water showed a significant difference in organic matter characteristics and fouling potential, highlighting the importance of biological processes and the feed water source on EfOM characteristics and fouling potential. On the basis of statistical analysis, protein-like substances were found to be highly correlated to the fouling potential of secondary effluents. © 2012 Elsevier Ltd.

    2016-01-01

    Full Text Available Cet article s’intéresse à la structure globale du lexique, en tant que module fonctionnel de la langue, et à ses possibles représentations formelles. Nous posons tout d’abord le problème de la représentation de la connaissance lexicale, en expliquant l’importance d’adopter une métaphore géométrique du lexique qui soit adaptée à l’étude lexicologique et à ses diverses applications. Cela nous amène préciser la nature même du lexique qui doit faire l’objet d’une telle géométrisation en revenant sur la notion souvent galvaudée de lexique mental et en distinguant deux types de lexiques mentaux – le lexique logique et le lexique physiologique –, dont seul le premier est notre objet d’étude. Après avoir examiné les principales métaphores courantes du lexique logique, nous présentons un modèle formel plausible, sur lequel s’appuie notamment le projet du Réseau Lexical du Français : il s’agit des Systèmes Lexicaux, dont la charpente structurale est constituée par les fonctions lexicales Sens-Texte.

    Full Text Available El largo y generalizado uso de las vacunas contra el sarampión se ha traducido en un drástico descenso en los casos y la mortalidad por sarampión en todo el mundo en comparación con la época anterior a la vacunación. Todas las regiones de la Organización Mundial de la Salud (OMS tienen el objetivo de conseguir su eliminación. Las regiones de la OMS de las Améri - cas, Europa y el Pacífico Occidental tienen, así mismo, la meta de eliminar la rubéola. Este artículo tiene como objetivo informar sobre el progreso hacia la eliminación del sarampión y la rubéola en la Región Europea de la OMS sobre la base de los últimos datos disponibles. También se discuten los retos actuales y las acciones necesarias para alcanzar este fin. A pesar de los importantes avances alcanzados hacia el control de sa - rampión y la rubéola, los países de la Región Europea de la OMS siguen enfrentando desafíos en la interrupción de la transmisión endémica de estas enfermedades. Algunos brotes epidémicos y la transmisión endémica del sa - rampión y la rubéola persistían en algunos países de la Región en 2014 y han continuado en 2015. La interrupción de la transmisión endémica en todos y cada uno de ellos es necesaria para declarar la eliminación en toda la Región. La alta inmunidad de la población y la vigilancia de alta calidad son los pilares para eliminar el sarampión y la rubéola. Sin la existencia de un compromiso político sostenido y de la aplicación de las estrategias requeri - das por parte de todos los países, el objetivo de la eliminación de estas dos enfermedades en la Región Europea de la OMS está en juego.

    2014-01-01

    Background Diminishing stigmatization for those with mental illnesses by health care providers (HCPs) is becoming a priority for programming and policy, as well as research. In order to be successful, we must accurately measure stigmatizing attitudes and behaviours among HCPs. The Opening Minds Stigma Scale for Health Care Providers (OMS-HC) was developed to measure stigma in HCP populations. In this study we revisit the factor structure and the responsiveness of the OMS-HC in a larger, more representative sample of HCPs that are more likely to be targets for anti-stigma interventions. Methods Baseline data were collected from HCPs (n = 1,523) during 12 different anti-stigma interventions across Canada. The majority of HCPs were women (77.4%) and were either physicians (MDs) (41.5%), nurses (17.0%), medical students (13.4%), or students in allied health programs (14.0%). Exploratory factor analysis (EFA) was conducted using complete pre-test (n = 1,305) survey data and responsiveness to change analyses was examined with pre and post matched data (n = 803). The internal consistency of the OMS-HC scale and subscales was evaluated using the Cronbach’s alpha coefficient. The scale’s sensitivity to change was examined using paired t-tests, effect sizes (Cohen’s d), and standardized response means (SRM). Results The EFA favored a 3-factor structure which accounted for 45.3% of the variance using 15 of 20 items. The overall internal consistency for the 15-item scale (α = 0.79) and three subscales (α = 0.67 to 0.68) was acceptable. Subgroup analysis showed the internal consistency was satisfactory across HCP groups including physicians and nurses (α = 0.66 to 0.78). Evidence for the scale’s responsiveness to change occurred across multiple samples, including student-targeted interventions and workshops for practicing HCPs. The Social Distance subscale had the weakest level of responsiveness (SRM ≤ 0.50) whereas the more attitudinal

    The clinical benefits of memantine, depending on the baseline cognitive and affective conditions in real world dementia clinics, have not been completely examined. We performed the "Okayama Memantine Study II (OMS II)" to retrospectively evaluate the clinical effects of memantine monotherapy (n = 38) in Alzheimer's disease (AD) patients using seven batteries to assess dementia at the baseline, at 3, 6, and 12 months. Additionally, we divided 163 AD patients treated with memantine into two subgroups depending on the baseline cognitive score of the Mini-Mental State Examination (MMSE): the MMSE OMS II showed that memantine monotherapy improved BPSD until 12 months. The higher baseline cognitive subgroup (MMSE ≥15) and the worse baseline BPSD subgroup were expected to show better effects with memantine.

    En undersøgelse af Hegels tolkning af sofisten Gorgias giver anledning til at se på receptionen af sofisterne hos notable filosofihistorikere i det 18. århundrede. En sådan undersøgelse viser, at Hegel har en original og velvillig tolkning af sofisterne koncentreret omkring begrebet Bildung og det...... at give grunde for noget. Hegels udlægning af Gorgias bygger på hans tolkning af eleaterne, især af Zenon. Når Hegel har en særlig tolkning af eleaterne, skyldes det hans egne mangeårige filosofiske bestræbelser, og en identificering af en særlig, immanent objektiv dialektik hos Zenon, som han finder......, at Gorgias fører videre. Hegels filosofiske forståelse er tilstrækkelig udviklet til at kunne knytte positive kommentarer til alle dele af diskussionen i Gorgias' ræsonnement Om det ikkeværende, eller Om naturen. Det lykkes dog bedst i forhold til de to første af Gorgias' tre underteser. I hegelsk perspektiv...

    Full Text Available Den direkte transmission af levende begivenheder har altid været TV- mediets særlige styrke, hvad enten det drejer sig om fodboldkampe, Lørdagskanalen eller kongebrylluper. Medieforskerne har da også interesseret sig for fjernsynets formidling af sportsbegivenheder og der er blevet lavet analyser af Kanaludsendelserne. Men hverken i Danmark eller andre steder har forskerne fundet det interessant at undersøge de store, ceremonielle mediebegivenheder. Det er Dayan & Katz´ projekt at udfylde dette tomrum i medie- og kul- turforskningen: Hvad er det, der fascinerer millioner ved disse TV- ceremonier, der ofte ikke blot henvender sig til et enkelt lands seere, men transmitteres til og ses af store dele af verden? Hvordan fungere disse begivenheder - hvad enten det drejer sig om Præsident Kennedys begravelse, Sadats besøg i Jerusalem, Månelandingen eller Watergate- høringerne - ideologisk, og hvilke interesser tjener de dermed i den politiske offentlighed? I denne artikel, der er et bearbejdet uddrag af den bog, projektet skal munde ud i, beskæftiger Dayan & Katz sig især med det de kalder "transformative" mediebegivenheder, dvs. TV-ceremonier der markerer, at et samfund står ved en tærskel mellem den herskende orden og en ny mulig orden, og som selv er et aktivt og aktiverende bidrag til forvand- lingen af kulturelle opfattelser og værdier. Artiklens perpektiv er udpræget tværvidenskabeligt, idet der trækkes på såvel kulturantropologiske (Levi-Strauss, Geertz, Turner som filosofiske (Bakhtin, Baudrillard, sprogteoretiske (Austin og traditionelt samfunds- videnskabelige/mediesociologiske (Boorstin arbejder.

    Shame is an ineffective tool in residency education that often results in depression, isolation, and worse patient care. This study aimed to assess burnout, depersonalization, and personal achievement levels in current oral and maxillofacial surgery (OMS) residents, to assess the prevalence of the use of shame in OMS residency training, and to determine whether there is a relation between shame exposure and resident burnout, depersonalization, and personal achievement levels. An anonymous 20-question cross-sectional survey was developed incorporating the Maslach Burnout Index and a previously validated shame questionnaire and sent to all OMS program directors affiliated with the American Association of Oral and Maxillofacial Surgeons for distribution among their respective residents in 2016. Univariate analyses were used to determine the distribution of the predictor (shame) and outcome (burnout) by gender and by frequency of shaming events. Multivariable logistic regression analysis was used to assess the relation of shame to burnout. A 2-sided P value less than .05 was considered statistically significant. Two hundred seventeen responses were received; 82% of respondents were men (n = 178), 95% were 25 to 34 years old (n = 206), and 58% (n = 126) were enrolled in a 4-year program. Frequently shamed residents were more likely to have depression (58 vs 22%; P < .0001), isolation (55 vs 22%; P < .0001), and poor job performance (50 vs 30%; P < .0001). Residents who were frequently shamed were more likely to experience moderate to severe burnout (odds ratio = 4.6; 95% confidence interval, 2.1-10.0; P < .001) and severe depersonalization (odds ratio = 5.1; 95% confidence interval, 2.1-12.0; P < .0001) than residents who had never or infrequently been shamed. There is a clear relation between the number of shame events and burnout and depersonalization levels. It is important to understand the negative impact that the experience of shame has on residents

    2018-04-01

    Aerosols have adverse effects on human health and air quality, changing Earth's energy balance and lead to climate change. The components of aerosol are important because of the different spectral characteristics. Based on the low hygroscopic and high scattering properties of organic matter (OM) in fine modal atmospheric aerosols, we develop an inversion algorithm using remote sensing to obtain aerosol components including black carbon (BC), organic matter (OM), ammonium nitrate-like (AN), dust-like (DU) components and aerosol water content (AW). In the algorithm, the microphysical characteristics (i.e. volume distribution and complex refractive index) of particulates are preliminarily separated to fine and coarse modes, and then aerosol components are retrieved using bimodal parameters. We execute the algorithm using remote sensing measurements of sun-sky radiometer at AERONET site (Beijing RADI) in a period from October of 2014 to January of 2015. The results show a reasonable distribution of aerosol components and a good fit for spectral feature calculations. The mean OM mass concentration in atmospheric column is account for 14.93% of the total and 56.34% of dry and fine-mode aerosol, being a fairly good correlation (R = 0.56) with the in situ observations near the surface layer.

  1. Prevention of recurrent rhinopharyngitis in at-risk children in France: a cost-effectiveness model for a nonspecific immunostimulating bacterial extract (OM-85 BV).

    To estimate the pharmacoeconomic impact for the French Social Security System of preventing recurrent acute rhinopharyngitis (RARP) in at-risk children with OM-85 BV, an immunostimulating agent indicated for the prevention of recurrences. A decision-analysis model. The probability of progression of the infection and of its associated care, the principal direct costs linked to them, and the effectiveness of OM-85 BV were established or calculated by reviewing the available literature (published between 1984 and 2000). Four experts validated the parameters and the model. For the French Social Security System, the mean direct cost for an acute rhinopharyngitis (ARP) infection was 49.39 Euro(2000 values). By using OM-85 BV prevention, 1.52 infections were prevented in 6 months saving 67.83 Euro on the costs of care for the recurrently infected child. Sensitivity analyses confirmed the robustness of the model and indicated a saving of between 6.28 Euro and 303.64 Euro in direct costs for each individual treated preventively. Threshold analyses showed that OM-85 BV prophylaxis is economically profitable if more than 0.15 infections are prevented and if direct costs of care of an ARP are greater than 4.78 Euro. Non-specific immunotherapy should be considered for the child at risk of RARP and administered in addition to other recommended measures. The economic savings for the community of using a medication for which the clinical effectiveness has been demonstrated should also be taken into account in assessing its usefulness.

    In this paper, we analyze the cosmological models in Einstein-Aether gravity, which is a modified theory of gravity in which a time-like vector field breaks the Lorentz symmetry. We use this formalism to analyse different cosmological models with different behavior of the scale factor. In this analysis, we use a certain functional dependence of the Dark Energy (DE) on the Hubble parameter H . It will be demonstrated that the Aether vector field has a non-trivial effect on these cosmological models. We also perform the Om diagnostic in Einstein-Aether gravity and we fit the parameters of the cosmological models using recent observational data.

  5. Omeprazole induces heme oxygenase-1 in fetal human pulmonary microvascular endothelial cells via hydrogen peroxide-independent Nrf2 signaling pathway

    2016-01-01

    Omeprazole (OM) is an aryl hydrocarbon receptor (AhR) agonist and a proton pump inhibitor that is used to treat humans with gastric acid related disorders. Recently, we showed that OM induces NAD (P) H quinone oxidoreductase-1 (NQO1) via nuclear factor erythroid 2-related factor 2 (Nrf2)-dependent mechanism. Heme oxygenase-1 (HO-1) is another cytoprotective and antioxidant enzyme that is regulated by Nrf2. Whether OM induces HO-1 in fetal human pulmonary microvascular endothelial cells (HPMEC) is unknown. Therefore, we tested the hypothesis that OM will induce HO-1 expression via Nrf2 in HPMEC. OM induced HO-1 mRNA and protein expression in a dose-dependent manner. siRNA-mediated knockdown of AhR failed to abrogate, whereas knockdown of Nrf2 abrogated HO-1 induction by OM. To identify the underlying molecular mechanisms, we determined the effects of OM on cellular hydrogen peroxide (H 2 O 2 ) levels since oxidative stress mediated by the latter is known to activate Nrf2. Interestingly, the concentration at which OM induced HO-1 also increased H 2 O 2 levels. Furthermore, H 2 O 2 independently augmented HO-1 expression. Although N-acetyl cysteine (NAC) significantly decreased H 2 O 2 levels in OM-treated cells, we observed that OM further increased HO-1 mRNA and protein expression in NAC-pretreated compared to vehicle-pretreated cells, suggesting that OM induces HO-1 via H 2 O 2 -independent mechanisms. In conclusion, we provide evidence that OM transcriptionally induces HO-1 via AhR - and H 2 O 2 - independent, but Nrf2 - dependent mechanisms. These results have important implications for human disorders where Nrf2 and HO-1 play a beneficial role. - Highlights: • Omeprazole induces HO-1 in human fetal lung cells. • AhR deficiency fails to abrogate omeprazole-mediated induction of HO-1. • Nrf2 knockdown abrogates omeprazole-mediated HO-1 induction in human lung cells. • Hydrogen peroxide depletion augments omeprazole-mediated induction of HO-1.

    Full Text Available O objetivo deste estudo é analisar as diferenças entre as prevalências de déficits de crescimento e excesso de peso em crianças de 0-60 meses obtidas a partir dos padrões de referência NCHS (2000 e OMS (2005. Trata-se de um estudo transversal em que foram avaliadas 119 crianças de 0-60 meses no ambulatório de pediatria do Hospital Universitário de Brasília (HUB. Os escolares foram classificados, conforme recomendação da OMS através dos índices Peso/Estatura e Estatura/Idade através dos padrões OMS 2005 e NCHS 2000. Para análise foram utilizados os programas WHO Anthro 2005 e SPSS 13.0. Detectou-se uma alta prevalência de déficits de peso e estatura e excesso de peso em crianças independente do método utilizado. Porém, estas foram maiores utilizando-se o referencial proposto pela OMS em 2005. Conclui-se que a utilização das novas curvas de crescimento (OMS deve ser imediata, uma vez que as mesmas têm maior representatividade que o referencial NCHS. Porém, independentemente do referencial utilizado, ações para sanar os problemas de déficits de peso e estatura e excesso de peso nas crianças devem ser iniciadas precocemente, já que desvios nutricionais podem aumentar a incidência de doenças crônicas.

  13. An engineering evaluation of the Space Shuttle OMS engine after 5 orbital flights

    1983-01-01

    Design features, performances on the first five flights, and condition of the Shuttle OMS engines are summarized. The engines were designed to provide a vacuum-fed 6000 lb of thrust and a 310 sec specific impulse, fueled by a combination of N2O4 and monomethylhydrazine (MMH) at a mixture ratio of 1.65. The design lifetime is 1000 starts and 15 hr of cumulative firing duration. The engine assembly is throat gimballed and features yaw actuators. No degradation of the hot components was observed during the first five flights, and the injector pattern maintained a uniform, enduring level of performance. An increase in the take-off loads have led to enhancing the wall thickness in the nozzle in affected areas. The engine is concluded to be performing to design specifications and is considered an operational system.

    Omeprazole (OM) is an aryl hydrocarbon receptor (AhR) agonist and a proton pump inhibitor that is used to treat humans with gastric acid related disorders. Recently, we showed that OM induces NAD (P) H quinone oxidoreductase-1 (NQO1) via nuclear factor erythroid 2-related factor 2 (Nrf2)-dependent mechanism. Heme oxygenase-1 (HO-1) is another cytoprotective and antioxidant enzyme that is regulated by Nrf2. Whether OM induces HO-1 in fetal human pulmonary microvascular endothelial cells (HPMEC) is unknown. Therefore, we tested the hypothesis that OM will induce HO-1 expression via Nrf2 in HPMEC. OM induced HO-1 mRNA and protein expression in a dose-dependent manner. siRNA-mediated knockdown of AhR failed to abrogate, whereas knockdown of Nrf2 abrogated HO-1 induction by OM. To identify the underlying molecular mechanisms, we determined the effects of OM on cellular hydrogen peroxide (H{sub 2}O{sub 2}) levels since oxidative stress mediated by the latter is known to activate Nrf2. Interestingly, the concentration at which OM induced HO-1 also increased H{sub 2}O{sub 2} levels. Furthermore, H{sub 2}O{sub 2} independently augmented HO-1 expression. Although N-acetyl cysteine (NAC) significantly decreased H{sub 2}O{sub 2} levels in OM-treated cells, we observed that OM further increased HO-1 mRNA and protein expression in NAC-pretreated compared to vehicle-pretreated cells, suggesting that OM induces HO-1 via H{sub 2}O{sub 2}-independent mechanisms. In conclusion, we provide evidence that OM transcriptionally induces HO-1 via AhR - and H{sub 2}O{sub 2} - independent, but Nrf2 - dependent mechanisms. These results have important implications for human disorders where Nrf2 and HO-1 play a beneficial role. - Highlights: • Omeprazole induces HO-1 in human fetal lung cells. • AhR deficiency fails to abrogate omeprazole-mediated induction of HO-1. • Nrf2 knockdown abrogates omeprazole-mediated HO-1 induction in human lung cells. • Hydrogen peroxide depletion augments

  3. Lille magt, men stort imperium. Et bidrag til debatten om TV og medieimperialisme

    1987-08-01

    Full Text Available Denne artikel tager fat i alt det svære - det begrebsmæssige - som vi enten springer over eller tager for givet i vores diskussioner af TV som magt- og påvirkningsfaktor. Derfor er den lang og til tider lidt omstændelig, idet den undgår at tage vores umiddelbare antagelser for pålydende. I stedet bliver de endevendt. I de seneste 15 års medieforskning har magten været implicit til stede et eller andet sted i TV. Vi har skiftevis kritiseret mediet, frygtet det, taget afstand fra det og er nu senest med receptionsteorierne blevet beroliget: Enhver TV-seer skaber ud fra sin egen sunde fornuft sin personlige opfattelse af "Dollars". Påvirkningen af hende er ikke længere producen- ternes eller medieforskernes eller Danmarks Radios ansvar, det er seerens eget. Medieimperialismen er dermed opløst, ihvertfald som undertrykkelsessystem. Det første kritikpunkt i Niels-Aage Nielsens diskussion er medie- imperialismeteorien. Den har ikke nogen teori om hvordan magten sætter sig igennem hævder han, idet den alene ved cirkler og pile focuserer på ensidigheden i "flow'et" fra USA med resten af verden som modtagere. Hvis det skal udtrykke en magtposition, må der være en relation mellem varestrømmene (basis og den ideologiske overbygning. Vi er vant til at antage, at denne relation findes, men hvordan sætter den sig igennem? Diskussion heraf er - i bedste fald - gået i stå. For at kunne gå videre her, tager Niels-Aage Nielsen et opgør med receptionsteoriens socialpsykologi og søger at afdække hvilken del af betydningsdannelsen, og dermed påvirkningen, som netop unddrager sig en receptionsanalyse, der bygger på seerens egne udsagn og uden f.eks. en psykoanalytisk tilgang. Betydningsproblemet skal endda diskuteres endnu mere pricipielt: Vi er i dag mindre enige end nogensinde om hvad der er TV's samfunds- mæssige funkitioner. Uklarheden hænger bl.a. sammen med at ideologi- begrebet gradvist forsvandt ud af medieforskningens hovedst

    Activation of the aryl hydrocarbon receptor (AhR) transcriptionally induces phase I (cytochrome P450 (CYP) 1A1) and phase II (NAD(P)H quinone oxidoreductase 1 (NQO1) detoxifying enzymes. The effects of the classical and nonclassical AhR ligands on phase I and II enzymes are well studied in human hepatocytes. Additionally, we observed that the proton pump inhibitor, omeprazole (OM), transcriptionally induces CYP1A1 in the human adenocarcinoma cell line, H441 cells via AhR. Whether OM activates AhR and induces the phase II enzyme, NAD(P)H quinone oxidoreductase 1 (NQO1), in fetal primary human pulmonary microvascular endothelial cells (HPMEC) is unknown. Therefore, we tested the hypothesis that OM will induce NQO1 in HPMEC via the AhR. The concentrations of OM used in our experiments did not result in cytotoxicity. OM activated AhR as evident by increased CYP1A1 mRNA expression. However, contrary to our hypothesis, OM increased NQO1 mRNA and protein via an AhR-independent mechanism as AhR knockdown failed to abrogate OM-mediated increase in NQO1 expression. Interestingly, OM activated Nrf2 as evident by increased phosphoNrf2 (S40) expression in OM-treated compared to vehicle-treated cells. Furthermore, Nrf2 knockdown abrogated OM-mediated increase in NQO1 expression. In conclusion, we provide evidence that OM induces NQO1 via AhR-independent, but Nrf2-dependent mechanisms. - Highlights: • We investigated whether omeprazole induces NQO1 in human fetal lung cells. • Omeprazole induces the phase II enzyme, NQO1, in human fetal lung cells. • AhR deficiency fails to abrogate omeprazole-mediated induction of NQO1. • Omeprazole increases phosphoNrf2 (S40) protein expression in human fetal lung cells. • Nrf2 knockdown abrogates the induction of NQO1 by omeprazole in human lung cells.

  5. Description of comprehensive pump test change to ASME OM code, subsection ISTB

    International Nuclear Information System (INIS)

    Hartley, R.S.

    1994-01-01

    The American Society of Mechanical Engineers (ASME) Operations and Maintenance (OM) Main Committee and Board on Nuclear Codes and Standards (BNCS) recently approved changes to ASME OM Code-1990, Subsection ISTB, Inservice Testing of Pumps in Light-Water Reactor Power Plants. The changes will be included in the 1994 addenda to ISTB. The changes, designated as the comprehensive pump test, incorporate a new, improved philosophy for testing safety-related pumps in nuclear power plants. An important philosophical difference between the open-quotes old codeclose quotes inservice testing (IST) requirements and these changes is that the changes concentrate on less frequent, more meaningful testing while minimizing damaging and uninformative low-flow testing. The comprehensive pump test change establishes a more involved biannual test for all pumps and significantly reduces the rigor of the quarterly test for standby pumps. The increased rigor and cost of the biannual comprehensive tests are offset by the reduced cost of testing and potential damage to the standby pumps, which comprise a large portion of the safety-related pumps at most plants. This paper provides background on the pump testing requirements, discusses potential industry benefits of the change, describes the development of the comprehensive pump test, and gives examples and reasons for many of the specific changes. This paper also describes additional changes to ISTB that will be included in the 1994 addenda that are associated with, but not part of, the comprehensive pump test

  14. The development and psychometric properties of a new scale to measure mental illness related stigma by health care providers: the Opening Minds Scale for Health Care Providers (OMS-HC).

    Research on the attitudes of health care providers towards people with mental illness has repeatedly shown that they may be stigmatizing. Many scales used to measure attitudes towards people with mental illness that exist today are not adequate because they do not have items that relate specifically to the role of the health care provider. We developed and tested a new scale called the Opening Minds Scale for Health Care Providers (OMS-HC). After item-pool generation, stakeholder consultations and content validation, focus groups were held with 64 health care providers/trainees and six people with lived experience of mental illness to develop the scale. The OMS-HC was then tested with 787 health care providers/trainees across Canada to determine its psychometric properties. The initial testing OMS-HC scale showed good internal consistency, Cronbach's alpha = 0.82 and satisfactory test-retest reliability, intraclass correlation = 0.66 (95% CI 0.54 to 0.75). The OMC-HC was only weakly correlated with social desirability, indicating that the social desirability bias was not likely to be a major determinant of OMS-HC scores. A factor analysis favoured a two-factor structure which accounted for 45% of the variance using 12 of the 20 items tested. The OMS-HC provides a good starting point for further validation as well as a tool that could be used in the evaluation of programs aimed at reducing mental illness related stigma by health care providers. The OMS-HC incorporates various dimensions of stigma with a modest number of items that can be used with busy health care providers.

Med udgangs-punkt i en undersøgelse fortaget i forbindelse med forfatterens ph.d.- projekt (afsluttet i sommeren 2014 vil artiklen på baggrund af en verserende debat om masteruddannelsernes kvalitet og relevans diskutere kvalitet i dansk akademisk videreuddannelse. Den kvalitative undersøgelse, der ligger til grund for artiklen, anskueliggør, at selvom de studerende oplever, at de gennem deres toårige studie har tilegnet sig en række konkrete og brugbare kompetencer, peger de på andre og mere transformative læringskvaliteter, når man beder dem om at beskrive det vigtigste udkomme af deres uddannelsesforløb. Artiklen argumenterer for, at denne læring, der i højere grad kan siges at knytte sig til personen i form af en etisk-eksistentiel dannelse frem for en specifik kunnen, har nær sammenhæng med det at befinde sig i et akademisk, videnskabeligt miljø. På dette grundlag søger artiklen at problematisere aktuelle forslag om at slække på kravet til masteruddannelsernes videnskabelige fundament for i stedet at fokusere på mere instrumentelle, erhvervsrettede kompetencer og færdigheder.

    The OM43 clade within the family Methylophilaceae of Betaproteobacteria represents a group of methylotrophs playing important roles in the metabolism of C1 compounds in marine environments and other aquatic environments around the globe. Using dilution-to-extinction cultivation techniques, we successfully isolated a novel species of this clade (designated here as MBRS-H7) from the ultra-oligotrophic open ocean waters of the central Red Sea. Phylogenomic analyses indicate that MBRS-H7 is a novel species, which forms a distinct cluster together with isolate KB13 from Hawaii (H-RS cluster) that is separate from that represented by strain HTCC2181 (from the Oregon coast). Phylogenetic analyses using the robust 16S–23S internal transcribed spacer revealed a potential ecotype separation of the marine OM43 clade members, which was further confirmed by metagenomic fragment recruitment analyses that showed trends of higher abundance in low chlorophyll and/or high temperature provinces for the H-RS cluster, but a preference for colder, highly productive waters for the HTCC2181 cluster. This potential environmentally driven niche differentiation is also reflected in the metabolic gene inventories, which in the case of H-RS include those conferring resistance to high levels of UV irradiation, temperature, and salinity. Interestingly, we also found different energy conservation modules between these OM43 subclades, namely the existence of the NADH:quinone oxidoreductase NUO system in the H-RS and the non-homologous NQR system in HTCC2181, which might have implications on their overall energetic yields.

    This paper describes a holistic approach to operation and maintenance (O&M) processes in the domain of offshore wind farm power generation. The acquisition and process visualization is followed by a risk analysis of all relevant processes. Hereafter, a tool was designed, which is able to model the defined processes in a BPMN 2.0 notation, as well as connect and simulate them. Furthermore, the notation was enriched with new elements, representing other relevant factors that were, to date, only displayable with much higher effort. In that regard a variety of more complex situations were integrated, such as for example new process interactions depending on different weather influences, in which case a stochastic weather generator was combined with the business simulation or other wind farm aspects important to the smooth running of the offshore wind farms. In addition, the choices for different methodologies, such as the simulation framework or the business process notation will be presented and elaborated depending on the impact they had on the development of the approach and the software solution. - Highlights: • Analysis of operation and maintenance processes of offshore wind farms • Process modeling with BPMN 2.0 • Domain-specific simulation tool.

L’objectif de ce travail était d’estimer les apports spontanés en acides alphalinolénique (ALA, docosahexaénoïque (DHA, éicosapentaénoïque (EPA et linoléique (LA. Cette étude d’observation a été réalisée auprès de 42 diabétiques de type 2 (21 hommes et 21 femmes âgés de 30 à 75 ans. L’estimation des apports en acides gras a été réalisée en utilisant la méthode d’enregistrement sur sept jours. Les résultats ont montré que l’apport moyen en ALA était de 0,99 ± 0,40 g/j soit 0,42 ± 0,13 % de l’apport énergétique total (AET. Aucun de nos patients n’avait un apport suffisant en ALA. Les apports quotidiens moyens en DHA et en EPA étaient respectivement de 90,0 ± 85 mg/j et de 83,5 ± 80 mg/j. Quant à la contribution des aliments aux apports en EPA et en DHA, les poissons et les fruits de mer représentaient la part la plus importante (57 % de ces deux acides gras. Nos résultats appellent à renforcer l’éducation nutritionnelle des diabétiques afin d’augmenter les apports en acides gras oméga 3 et d’assurer un rapport LA/ALA optimal qui contribuerait à la prévention des maladies cardiovasculaires.

  8. Code cases for implementing risk-based inservice testing in the ASME OM code

    International Nuclear Information System (INIS)

    Rowley, C.W.

    1996-01-01

    Historically inservice testing has been reasonably effective, but quite costly. Recent applications of plant PRAs to the scope of the IST program have demonstrated that of the 30 pumps and 500 valves in the typical plant IST program, less than half of the pumps and ten percent of the valves are risk significant. The way the ASME plans to tackle this overly-conservative scope for IST components is to use the PRA and plant expert panels to create a two tier IST component categorization scheme. The PRA provides the quantitative risk information and the plant expert panel blends the quantitative and deterministic information to place the IST component into one of two categories: More Safety Significant Component (MSSC) or Less Safety Significant Component (LSSC). With all the pumps and valves in the IST program placed in MSSC or LSSC categories, two different testing strategies will be applied. The testing strategies will be unique for the type of component, such as centrifugal pump, positive displacement pump, MOV, AOV, SOV, SRV, PORV, HOV, CV, and MV. A series of OM Code Cases are being developed to capture this process for a plant to use. One Code Case will be for Component Importance Ranking. The remaining Code Cases will develop the MSSC and LSSC testing strategy for type of component. These Code Cases are planned for publication in early 1997. Later, after some industry application of the Code Cases, the alternative Code Case requirements will gravitate to the ASME OM Code as appendices

    Since 2006 we have carried out active space experiments using the transport spacecraft (TSC) "Progress" and the ground-base Radio-Optic Complex of ISTP SB RAS including Irkutsk Incoherent Scatter Radar (IISR). Engine burns of TSC orbital maneuvering subsystem (OMS) were used as a source of ionospheric disturbances and changing radar signature characteristics of TSC. The flight altitudes were about 340 km. The amount of engine exhaust products was varied from 2 to 11 kg. The flow directions relative to IISR and amount of injected exhaust products were changed from flight to flight. The flows directed to IISR were almost parallel to the geomagnetic field line. For these cases the most pronounced effects were observed, the electron density depletion reached 20-40

    2011-03-01

    The aim of the study was to test the hypothesis that B-cell repopulation following rituximab (anti-CD20) therapy is orchestrated by chemokines and non-chemokine cytokines. Twenty-five children with opsoclonus-myoclonus syndrome (OMS) received rituximab with or without conventional agents. A comprehensive panel of 40 chemokines and other cytokines were measured in serum by ELISA and multiplexed fluorescent bead-based immunoassay. Serum BAFF concentration changed dramatically (even after first infusion) and inversely with B-cell depletion/repopulation and CXCL13 concentration at 1, 3, and 6 months. Negative correlations were found for BAFF concentration vs blood B cell percentage and serum CXCL13 concentration; positive correlations with serum rituximab concentrations. Six months after initiation of therapy, no significant difference in the levels of APRIL, CXCL10, IL-6, or 17 other cytokines/chemokines were detected. These data reveal a major role for BAFF in peripheral B cell repopulation following rituximab-induced B-cell depletion, and novel changes in CXCL13. ClinicalTrials.gov NCT0024436.

    Full Text Available Abstract: This article describes 10 year old children`s play in nature during school hours. However, my result does equally reflect on children in kindergarden as well. Observation and conversation was used as methods as well as pictures. The children’s play in the trees and building huts was conducted in groups, and their communication was nonverbal with each other and with the nature. However; the girls reveal that they enjoy their conversations while being in the tree. The children often play at the same place over and over. This is significant to the evolution of the play and the children’s communication with their places in nature.Sammendrag: Denne artikkelen omhandler 10 år gamle barns lek på natursteder i skoletida. Selv om studien omhandler 10 åringer så kan kunnskapen den frembringer også være viktig for å forstå barnehagebarns lek og tilknytning til sine lekesteder i barnehagen. Metodene som ble brukt for å undersøke barnas lek var observasjoner og samtaler med barna, i tillegg til fotografier. Barnas lek i trærne og i hyttebyggingen karakteriseres ved at de er flere sammen, og barna har en kroppslig dialog med hverandre og omgivelsene i leken. Barna snakker i liten grad sammen om leken og hvordan de skal leke; deres kommunikasjon er hovedsakelig nonverbal. Men når jentene sitter i treet forteller de meg at de liker å sitte og snakke. Barna leker på steder hvor de har vært mye før, og dette har en betydning for barnas lek og barnas kommunikasjon med deres steder.

    Francisco Javier Acosta Artiles

    2017-01-01

    Full Text Available La exposición inadecuada en los medios de comunicación sobre suicidios puede producir un efecto contagio o efecto Werther , mientras que determinadas características adecuadas pueden tener un efecto protector o efecto Papageno . Por tanto, los medios de comunicación pueden contribuir a la prevención del suicidio. Por ello, la OMS ha elaborado tres documen- tos con una serie de recomendaciones dirigidas a los profesionales de los medios de comunicación, para el tratamiento de las noticias relacionadas con el suicidio. Sin embargo, solo se ha traducido al español el primero, ambos tienen solapamientos y poseen una estructura diferente. Esto supone que los profesionales de los medios de comunicación de habla hispana en general, y de España en particular, difícilmente pueden tener un acceso a estas recomendaciones de la OMS de una forma clara y concisa. El objetivo de este trabajo fue la elaboración y provisión de un texto único y sintético que recogiera las recomendaciones de estos documentos. Para su creación se siguió un procedimiento formal y estructurado, que aunó criterios científicos y lingüísticos. El texto final contiene las recomendaciones agrupadas en tres categorías: “qué hacer”, “qué no hacer” y “otras recomendaciones”. Este documento puede ser de gran utilidad para los profesionales de los medios de comunicación, para actividades formativas de difusión de tales recomen- daciones con finalidad preventiva y para la investigación.

  20. Comprehensive Genomic Analyses of the OM43 Clade, Including a Novel Species from the Red Sea, Indicate Ecotype Differentiation among Marine Methylotrophs

    The OM43 clade within the family Methylophilaceae of Betaproteobacteria represents a group of methylotrophs that play important roles in the metabolism of C1 compounds in marine environments and other aquatic environments around the globe. Using dilution-to-extinction cultivation techniques, we successfully isolated a novel species of this clade (here designated MBRS-H7) from the ultraoligotrophic open ocean waters of the central Red Sea. Phylogenomic analyses indicate that MBRS-H7 is a novel species that forms a distinct cluster together with isolate KB13 from Hawaii (Hawaii-Red Sea [H-RS] cluster) that is separate from the cluster represented by strain HTCC2181 (from the Oregon coast). Phylogenetic analyses using the robust 16S-23S internal transcribed spacer revealed a potential ecotype separation of the marine OM43 clade members, which was further confirmed by metagenomic fragment recruitment analyses that showed trends of higher abundance in low-chlorophyll and/or high-temperature provinces for the H-RS cluster but a preference for colder, highly productive waters for the HTCC2181 cluster. This potential environmentally driven niche differentiation is also reflected in the metabolic gene inventories, which in the case of the H-RS cluster include those conferring resistance to high levels of UV irradiation, temperature, and salinity. Interestingly, we also found different energy conservation modules between these OM43 subclades, namely, the existence of the NADH:quinone oxidoreductase complex I (NUO) system in the H-RS cluster and the nonhomologous NADH:quinone oxidoreductase (NQR) system in the HTCC2181 cluster, which might have implications for their overall energetic yields.

Os adubos foram empregados somente no primeiro ano, 1943-44, mas o ensaio foi conduzido durante três anos. O efeito do fósforo foi muito pequeno (provavelmente porque a terra havia sido adubada com adubos fosfatados nas culturas anteriores ao ensaio, ao passo que o potássio aumentou extraordinariamente a produção no primeiro ano e teve magnífico efeito residual nos dois anos seguintes.

    Full Text Available Abstract Background Research on the attitudes of health care providers towards people with mental illness has repeatedly shown that they may be stigmatizing. Many scales used to measure attitudes towards people with mental illness that exist today are not adequate because they do not have items that relate specifically to the role of the health care provider. Methods We developed and tested a new scale called the Opening Minds Scale for Health Care Providers (OMS-HC. After item-pool generation, stakeholder consultations and content validation, focus groups were held with 64 health care providers/trainees and six people with lived experience of mental illness to develop the scale. The OMS-HC was then tested with 787 health care providers/trainees across Canada to determine its psychometric properties. Results The initial testing OMS-HC scale showed good internal consistency, Cronbach’s alpha = 0.82 and satisfactory test-retest reliability, intraclass correlation = 0.66 (95% CI 0.54 to 0.75. The OMC-HC was only weakly correlated with social desirability, indicating that the social desirability bias was not likely to be a major determinant of OMS-HC scores. A factor analysis favoured a two-factor structure which accounted for 45% of the variance using 12 of the 20 items tested. Conclusions The OMS–HC provides a good starting point for further validation as well as a tool that could be used in the evaluation of programs aimed at reducing mental illness related stigma by health care providers. The OMS-HC incorporates various dimensions of stigma with a modest number of items that can be used with busy health care providers.

  7. Å ta spørsmål om form på alvor

    Directory of Open Access Journals (Sweden)

    Full Text Available I dette essayet vil jeg prøve å vise hvordan Åpen forms metode, som ble utviklet i Bergen på 1970-tallet, og som senere har blitt brukt i undervisninga ved Bergen arkitekthøgskole, også kan anvendes som verktøy i faget kunst og håndverk i grunnskolelærerutdanninga. Åpen form undersøker et intersubjektivt og innovativt rom, tuftet på individets erfaringsverden, egenverdi og skapende mot. I et deltakende samspill kan Åpen form kommuniseres inn i en felles forståelse, tolket, utført, vist og avklaret gjennom praktiske handlinger og øvelser. Jeg tar utgangspunkt i 1 Viktor Papaneks tilnærming med at det å forme i seg selv er en grunnleggende menneskelig aktivitet, går videre til Hansjörg Hohrs «estetiske læreprosesser» og fortsetter med 2 Oskar Hansens begrep om «Open Form», praktisert og utviklet av Svein Hatløy og arkitektgruppa Gult Felt gjennom ulike symposier og prosjekter på Vestlandet. Den åpne tilnærminga til form blir belyst spesielt med 3 «Warszawa-spelet» og med et lite eksempel fra egen didaktisk praksis. For videre å underbygge en kunstdidaktisk tilnærming, tolker jeg 4 Åpen forms metode i et fenomenologisk perspektiv og avrunder essayet med min overbevisning om 5 «det estetiske som kunnskapsform» i forlengelse av definisjonen til pedagogene Austring og Sørensen og min egen erfaring fra praksis som kunstner og som lærer i arbeid med form. Åpen form som metode har referanser i kunstfeltets mangfoldige estetiske praksiser. Denne tenkinga kan la seg utvikle og bruke som en didaktisk formel også i mer almendannende undervisning. Som lærerutdanner med kunstfaglig bakgrunn, ser jeg her en mulighet til å styrke og synliggjøre estetiske læreprosesser i grunnskolelærerutdanninga. Metoden representerer en åpen og praktisk undersøkende holdning til form i et materielt og romlig uttrykk. I et forsøk på å løfte fram dette enkle men anvendelige tenkesettet, vil jeg trekke inn både biografiske og

  9. Afmystificering af studerendes forestillinger om forskning: et studenterperspektiv på forskningsbaseret undervisning

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available Litteraturen om, hvorledes forskning og undervisning kan integreres på uddannelsesinstitutioner, er vokset betragteligt i de seneste år. Derimod har kun få af disse studier beskæftiget sig med, hvordan studerende oplever forholdet mellem forskning og undervisning. Baseret på et kvalitativt studie af studerendes oplevelse af et forskningsbaseret undervisningsforløb, nærmere bestemt et forskningspraktikforløb, vil denne artikel bidrage til diskussionen med et studenterperspektiv. Vores data viser, at studerende, til trods for at have gennemgået dette forskningsbaserede læringsforløb, stadig oplever forskning og undervisning som adskilte. Vi vil derfor argumentere, at studerende drager et konceptuelt skel mellem forskning og undervisning og betragter disse som to divergerende praksisser. Gennem en analyse af vores data, vil vi vise, at forskningspraktik leder til en afmystificering af studerendes forestillinger om forskning, hvilket udfordrer dette skel. I konklusionen påpeger vi, at en bedre integration af forskning og undervisning kan ske, hvis studerende introduceres til forskningsprocesser gennem hele deres uddannelse. Abstract Literature promoting a close relationship between research and teaching in university has increased significantly in recent years. A walk-through of this literature, shows that only few of these studies have investigated the students’ perspective, though. We intend to fill this gap, by contributing with a qualitative study of students’ experience of research based teaching. This study shows how students experience a divide between research and teaching. This divide, we argue, is primarily on a conceptual level, where the two practices and considered fundamentally different. Our data shows how an internship can lead to a demystification process for these students. This lead to a reevaluation of the conceptual boundary. We argue that a larger focus on research based teaching, throughout the university

    2015-07-01

    Opsoclonus myoclonus syndrome (OMS) produces long-term cognitive, behavioral, and motor deficits. Objective was to see if more aggressive treatment improved outcome. Assessment included opsoclonus myoclonus syndrome rating, developmental/cognitive and motor assessment, and adaptive behavior. Fourteen subjects completed testing. Nine had neuroblastoma. Onset was at 10 to 35 months; onset to diagnosis: 2 days to 14 months, and onset to first treatment: 5 days to 15 months. Initial treatment was corticotropin (12), oral steroids (3), plus intravenous immunoglobulin in all. Ten received rituximab, 5 cyclophosphamide. Age at testing ranged from 2.5 to 10.3 years. Adaptive Behavior Score (11 subjects), mean 93.5; estimated Intelligence Quotient/Developmental Quotient mean 93.5; Motor: mean 92.8. Residual opsoclonus myoclonus syndrome symptoms at the time of the evaluation were generally minor; opsoclonus myoclonus syndrome scores ranged from 0 to 6. Comparison to previously reported opsoclonus myoclonus syndrome subjects showed improved outcomes: Adaptive behavior, cognitive and motor scores were significantly higher (P < .001) in new subjects. Outcomes have improved with more aggressive immunosuppression, with most opsoclonus myoclonus syndrome survivors now functioning at or near normal. © The Author(s) 2014.

  12. RDFBuilder: a tool to automatically build RDF-based interfaces for MAGE-OM microarray data sources.

    Science.gov (United States)

    Anguita, Alberto; Martin, Luis; Garcia-Remesal, Miguel; Maojo, Victor

    2013-07-01

    This paper presents RDFBuilder, a tool that enables RDF-based access to MAGE-ML-compliant microarray databases. We have developed a system that automatically transforms the MAGE-OM model and microarray data stored in the ArrayExpress database into RDF format. Additionally, the system automatically enables a SPARQL endpoint. This allows users to execute SPARQL queries for retrieving microarray data, either from specific experiments or from more than one experiment at a time. Our system optimizes response times by caching and reusing information from previous queries. In this paper, we describe our methods for achieving this transformation. We show that our approach is complementary to other existing initiatives, such as Bio2RDF, for accessing and retrieving data from the ArrayExpress database. Copyright © 2013 Elsevier Ireland Ltd.

    Marte Sørebø Gulliksen

    2013-01-01

    Full Text Available Artikkelen belyser og diskuterer læreres fagdidaktiske utvelgelseskompetanse i formgiving, kunst og håndverk. Det introduseres en antakelse om at det er mulig og nyttig å anlegge et valgperspektiv på didaktiske handlinger. Det pekes innledningsvis på en del utfordringer med lærerkunnskap, innhold, arbeidsformer og vurdering i faget, knyttet til de krav utfordringene stiller til lærerens utvelgelseskompetanse. Vygotskijs teorier omkring lånte erfaringer og bedømmelses­teorien til Kahneman & Tversky og Kahneman & Fredricks presenteres som et utvalgt teoretisk perspektiv. Det pekes på eksempler fra empiriske studier som har studert faglærerutdanningen i formgiving, kunst og håndverk. Fra disse presenteres og diskuteres situasjoner der valgproblematikk er avgjørende for studentenes læring og mestring av kommende yrkesutøvelse. Valgperspektivet viser seg å kunne gi en mulighet til å se nye potensielle strukturer i den komplekse situasjonen lærerutdanningen i formgiving, kunst og håndverk er: Perspektivet kunne belyse hvordan uklarhet omkring valgmuligheter førte til begrensning. Dessuten kunne det bidra til å problematisere sider av faglærerutdanningens spesialitet: Utfordringen det er å kombinere egen utøving i skapende arbeid og didaktisk utøving- og undervisningskompetanse. Det blir konkludert med at mer forskning er nødvendig, og det blir pekt på at et pågående forskningsprosjekt forhåpentligvis vil kunne bidra til dette, både ved å dokumentere den enkeltes erfaring og ved å studere kritisk om eksemplene i denne artikkelen kan sies å være aktuelle i flere situasjoner. Denne kunnskapen vil kunne styrke det forskningsbaserte grunnlaget for å utdanne lærere med nok utvelgelses­kompetanse til å gjøre gode valg.

    2012-10-01

    Three ordered mesoporous siliceous (OMS) materials known as MCM41s-unmodified MCM-41C16 ("C16"), and two MCM41s with different surface functionalities: MCM-41C16-SH ("C16-SH") and MCM-41C16-NH 2 ("C16-NH 2 ")-were synthesized and studied by inverse gas chromatography in order to determine their acceptor-donor properties. The specific retention volumes of nonpolar and polar probes that were chromatographed on these ordered mesoporous silica adsorbents were evaluated under infinite dilution conditions. Two methods were employed to calculate the standard free energy of adsorption, Δ G ads , of each chromatographed probe on the basis its specific retention volume. These Δ G ads values were then employed to estimate the van der Waals contribution and the specific contribution of the free surface energy for each MCM41. DN values (donor numbers, based on the Gutmann scale) and AN* values (acceptor numbers, based on the Riddle-Fowkes scale) were employed to determine the values of parameters that characterize the ability of the MCM41s to act as electron acceptors (parameter: K A ) and donors (parameter: K D ). Considering the different compositions of the probes, each of which has different acceptor-donor properties, a new chromatographic test to supplement the Grob test is suggested.

  7. Uten lovlig opphold = uten rettigheter? Tilværelsen til migranter uten oppholdstillatelse i lys av normativ teori om rettferdighet

    2012-11-01

    Full Text Available Migranter som fortsetter å oppholde seg i et land etter avslag på søknad om opphold, eller som unnlater å søke om oppholdstillatelse, utfordrer det juridiske rammeverket for nasjonalstater og statsborgerskap. I denne artikkelen diskuteres livssituasjonen til migranter uten lovlig opphold opp mot normativ kosmopolitisk teori om universelle rettigheter. Dette er belyst i internasjonal litteratur, men i mindre grad innenfor en norsk kontekst. Vi tar i denne artikkelen for oss tre empiriske eksempler: tilværelsen i såkalte ventemottak, tilværelsen utenfor ventemottakene og tilværelsen for barn uten lovlig opphold. Gjennom eksemplene diskuterer vi rettighetsspørsmål i migrantenes liv. Vi viser hvordan menneskerettighetene ikke er tilstrekkelige for å ivareta migrantenes velvære, og hvordan rettigheter migrantene faktisk har, ikke fremstår som reelle fordi det oppleves som risikabelt å benytte seg av dem. Artikkelen setter normativ kosmopolitisk teori i perspektiv ved å diskutere den konkrete situasjonen til migrantene, og spør til slutt hva som kan være konsekvensene av at rettigheter blir ulikt fordelt?Nøkkelord: rettferdighet, rettigheter, migrasjon, ulovlig opphold, kosmopolitismeEnglish summary: Without legal residency = no rights? A discussion of the situation of migrants who have settled without official authorisation, in light of the normative theory of justiceMigrants who continue to reside in a country after having received a negative answer to their residence application, or who stay without registering themselves in the first place, challenge the legal framework of national states and citizenship. In this article, we illustrate the situation of migrants without legal residence in light of normative cosmopolitan theory focusing on the universality of rights. We discuss three empirical contexts: life in the so-called waiting reception centers, life outside the waiting reception centers, and the situation of children

    2018-06-01

    In this paper, we propose a new parametrization for Om(z) diagnostics and show how the most recent and significantly improved observations concerning the H(z) and SN Ia measurements can be used to probe the consistency or tension between the ΛCDM model and observations. Our results demonstrate that H 0 plays a very important role in the consistency test of ΛCDM with H(z) data. Adopting the Hubble constant priors from Planck 2013 and Riess, one finds considerable tension between the current H(z) data and ΛCDM model and confirms the conclusions obtained previously by others. However, with the Hubble constant prior taken from WMAP9, the discrepancy between H(z) data and ΛCDM disappears, i.e., the current H(z) observations still support the cosmological constant scenario. This conclusion is also supported by the results derived from the Joint Light-curve Analysis (JLA) SN Ia sample. The best-fit Hubble constant from the combination of H(z)+JLA ({H}0={68.81}-1.49+1.50 km s‑1 Mpc‑1) is very consistent with results derived both by Planck 2013 and WMAP9, but is significantly different from the recent local measurement by Riess.

    Full Text Available Artiklen diskuterer, hvorvidt man efter Golfkrigen kan tale om en ‘Revolu- tion in Military Affairs’ – RMA – som nogle amerikanske krigsteoretikere hævder har fundet sted med anvendelsen af ny teknologi i moderne krigs- førelse. Forfatteren viser, hvordan moderne krigsstrategier har inkorpore- ret ny teknologi og mediebrug som bl.a. informationskrig, ‘Systems of Sys- tems’ og Network Centric Warfare. Forfatteren påpeger, at den strategiske anvendelse af informationsoperationer – herunder ‘embedded’ journalister – ikke har medført en demokratisering af nyhedsdækningen og heller ikke indebærer en øget sandhedsværdi. Afslutningsvis peger forfatteren på behovet for en ‘Revolution in Diplomatic Affairs’.

    Enligt Lpfö-98 skall man på förskolan arbeta med att barnen utvecklar sin förmåga att upptäcka och använda matematik i meningsfulla sammanhang. Jag tror att en förutsättning för en lyckad förskoleverksamhet är att man har föräldrarnas stöd och intresse i de aktiviteter som förekommer och har därför genom enkäter undersökt hur föräldrar uppfattar matematik i förskolan, viken inställning de har, samt deras eventuella tankar om utformningen.

    Full Text Available Artikkelen presenterer to nyere studier av veiledning i praksisopplæring i allmennlærerutdannelsen. Hovedfunnene drøftes i forhold til noen tidligere nordiske forskningsstudier. Studiene redegjør for intensjoner og realiteter i praksisopplæringen med fokus på mål, innhold og form i praksisveiledningen. Materialet er ramme- og fagplaner og intervjuer og observasjoner ved tre praksisskoler. Veiledningen drøftes i forhold til teori om veiledning. De to studiene som presenteres, konkluderer med at avstanden mellom teoridel og praksisdel i lærerutdannelsen fortsatt eksisterer. Det blir konstatert både fellestrekk og forskjeller mellom skolene når det gjelder graden av individuell veiledning og gruppeveiledning og individuell studentundervisning. Innholdsfokus i veiledningen varierte. Veilederrollen varierte mellom ettergivenhet og pågåenhet. Noen forskningsstudier hevder at øvingslærere praktiserer teknologisk veiledning. Artikkelen argumenterer for at innvielse i undervisningstradisjonen er nødvendig.

    Induction of the innate immune pathways is critical for early anti-viral defense but there is limited understanding of how teleost fish recognize viral molecules and activate these pathways. In mammals, Toll-like receptors (TLR) 7 and 8 bind single-stranded RNA of viral origin and are activated by synthetic anti-viral imidazoquinoline compounds. Herein, we identify and describe the rainbow trout (Oncorhynchus mykiss) TLR7 and TLR8 gene orthologs and their mRNA expression. Two TLR7/8 loci were identified from a rainbow trout bacterial artificial chromosome (BAC) library using DNA fingerprinting and genetic linkage analyses. Direct sequencing of two representative BACs revealed intact omTLR7 and omTLR8a1 open reading frames (ORFs) located on chromosome 3 and a second locus on chromosome 22 that contains an omTLR8a2 ORF and a putative TLR7 pseudogene. We used the omTLR8a1/2 nomenclature for the two trout TLR8 genes as phylogenetic analysis revealed that they and all the other teleost TLR8 genes sequenced to date are similar to the zebrafish TLR8a, but are distinct from the zebrafish TLR8b. The duplicated trout loci exhibit conserved synteny with other fish genomes extending beyond the tandem of TLR7/8 genes. The trout TLR7 and 8a1/2 genes are composed of a single large exon similar to all other described TLR7/8 genes. The omTLR7 ORF is predicted to encode a 1049 amino acid (aa) protein with 84% similarity to the Fugu TLR7 and a conserved pattern of predicted leucine-rich repeats (LRR). The omTLR8a1 and omTLR8a2 are predicted to encode 1035- and 1034-aa proteins, respectively, and have 86% similarity to each other. omTLR8a1 is likely the ortholog of the only Atlantic salmon TLR8 gene described to date as they have 95% aa sequence similarity. The tissue expression profiles of omTLR7, omTLR8a1 and omTLR8a2 in healthy trout were highest in spleen tissue followed by anterior and then posterior kidney tissues. Rainbow trout anterior kidney leukocytes produced elevated

  20. Germline BAP1 inactivation is preferentially associated with metastatic ocular melanoma and cutaneous-ocular melanoma families.

    Directory of Open Access Journals (Sweden)

    Ching-Ni Jenny Njauw

    Full Text Available BAP1 has been shown to be a target of both somatic alteration in high-risk ocular melanomas (OM and germline inactivation in a few individuals from cancer-prone families. These findings suggest that constitutional BAP1 changes may predispose individuals to metastatic OM and that familial permeation of deleterious alleles could delineate a new cancer syndrome.To characterize BAP1's contribution to melanoma risk, we sequenced BAP1 in a set of 100 patients with OM, including 50 metastatic OM cases and 50 matched non-metastatic OM controls, and 200 individuals with cutaneous melanoma (CM including 7 CM patients from CM-OM families and 193 CM patients from CM-non-OM kindreds.Germline BAP1 mutations were detected in 4/50 patients with metastatic OM and 0/50 cases of non-metastatic OM (8% vs. 0%, p = 0.059. Since 2/4 of the BAP1 carriers reported a family history of CM, we analyzed 200 additional hereditary CM patients and found mutations in 2/7 CM probands from CM-OM families and 1/193 probands from CM-non-OM kindreds (29% vs. 0.52%, p = .003. Germline mutations co-segregated with both CM and OM phenotypes and were associated with the presence of unique nevoid melanomas and highly atypical nevoid melanoma-like melanocytic proliferations (NEMMPs. Interestingly, 7/14 germline variants identified to date reside in C-terminus suggesting that the BRCA1 binding domain is important in cancer predisposition.Germline BAP1 mutations are associated with a more aggressive OM phenotype and a recurrent phenotypic complex of cutaneous/ocular melanoma, atypical melanocytic proliferations and other internal neoplasms (ie.

    A multifunctional heterojunctioned K-OMS-2/TiO(2)/Fe(3)O(4) (KTF) nanocomposite was successfully synthesized using a combination of hydrothermal and co-precipitation techniques. The resultant sample was characterized by XRD, FESEM, TEM, N(2) adsorption, XPS and VSM. Its photocatalytic activity was demonstrated in the photocatalytic degradation of humic acid (HA). Morphology characterization showed the hierarchical structure of the synthesized material, and XRD results revealed that both the rutile and anatase TiO(2) structures are present in the sample. The average pore diameters and BET surface area of the synthesized KTF heterojunctions were 40 nm and 134.42 m(2)/g, respectively. XPS spectra confirmed the presence of Fe(3)O(4) and TiO(2) in the synthesized material, and the valences of Mn were kept at +3 and +4 after the grafting of Fe(3)O(4) and TiO(2). The synthesized material showed good magnetic response and photocatalytic activity under simulated solar light irradiation, and 85.7% of HA was decomposed after 120 min in the presence of KTF nanocomposites. The reusability study suggested that the magnetic recovered material was stable enough for multiple recycling usages, verifying its potential application in water purification.

    2018-04-01

    Full Text Available Artikeln beskriver svensklärares interaktion och samstämmighet i samtal om summativ bedömning av gymnasieelevers skrivande. I ett dialogiskt perspektiv (Linell, 2011 undersöks interaktionella mönster avseende dominans, dynamik och koherens i tre svensklärargruppers bedömningssamtal. Dessa interaktionella mönster ställs i relation till uttryck för samstämmighet inom och mellan lärargrupperna. Resultatet visar att lärarna uttrycker hög grad av samstämmighet i bedömningssamtalen men att de bedömningar som lärarna gör enskilt i anslutning till samtalen enbart till viss del överensstämmer med gruppens beslut. Lägst grad av samstämmighet uppvisar den lärargrupp som i samtalen framstod som mest samstämmig. Där kännetecknas beslutsprocesserna av låg intensitet genom att få alternativ till bedömningar prövas. I de lärargrupper där intensiteten är högre genom att flera lärare styr samtalet i olika riktningar och där lärarna tillsammans prövar flera olika förslag på bedömning överensstämmer även enskilda lärares bedömningar i högre grad med gruppens beslut. Bedömningsöverensstämmelsen mellan lärargrupperna är däremot låg.

  8. Role of Streptococcus pneumoniae OM001 operon in capsular polysaccharide production, virulence and survival in human saliva.

    Streptococcus pneumoniae is the leading cause of community-acquired pneumonia in all ages worldwide, and with ever-increasing antibiotic resistance, the understanding of its pathogenesis and spread is as important as ever. Recently, we reported the presence of a Low Molecular Weight Tyrosine Phosphatase (LMWPTP) Spd1837 in the pneumococcus. This protein is encoded in an operon, OM001 with two other genes, with previous work implicating this operon as important for pneumococcal virulence. Thus, we set out to investigate the role of the individual genes in the operon during pneumococcal pathogenesis. As LMWPTPs play a major role in capsular polysaccharide (CPS) biosynthesis in many bacteria, we tested the effect of mutating spd1837 and its adjacent genes, spd1836 and spd1838 on CPS levels. Our results suggest that individual deletion of the genes, including the LMWPTP, did not modulate CPS levels, in multiple conditions, and in different strain backgrounds. Following in vivo studies, Spd1836 was identified as a novel virulence factor during pneumococcal invasive disease, in both the lungs and blood, with this protein alone responsible for the effects of operon's role in virulence. We also showed that a deletion in spd1836, spd1838 or the overall OM001 operon reduced survival in human saliva during the conditions that mimic transmission compared to the wildtype strain. With studies suggesting that survival in human saliva may be important for transmission, this study identifies Spd1836 and Spd1838 as transmission factors, potentially facilitating the spread of the pneumococcus from person to person. Overall, this study hopes to further our understanding of the bacterial transmission that precedes disease and outbreaks.

    Full Text Available Abstrakt: This article explores knowledge related to the gaze of the kindergarten teachers. By considering performances of the eyes as aspects of professionalism, the article discusses how different arrangements of the gaze are generated in complex conditions of judgment and power. Just as the eyeballs lies deeply tied into the corpus, both the gaze and the knowledge of the kindergarten teachers are deeply tied together in a comprehensive body of knowledge. This article draws upon interviews of kindergarten teachers related to mapping of children’s skills in a Norwegian context.  However, the statements in the study bring in a larger web of judgements in kindergarten. Foucault's theories are chosen as step stones for the discussion.Samandrag: Denne artikkelen handlar om kunnskapskonstruksjonar knytte til barnehagelæraren sitt blikk, og tek føre seg korleis barnehagelæraren bruker blikket i utøvinga av profesjonen sin.

Slik augeepla ligg djupt kopla saman med resten av kroppen, er også blikket og kunnskapen til barnehagelæraren djupt kopla saman i ein omfattande kunnskapskropp. Artikkelen tek utgangspunkt i gruppeintervju med barnehagelærarar om kartlegging av barn i ein norsk barnehagekontekst, men utsegnene frå intervjua bringar òg inn ein større vev av vurderingsarbeid i barnehagen.

    Full Text Available Siden anden verdenskrig er antallet af studerende på videregående uddannelser øget dramatisk. Som noget nyt har også professionsbachelorer adgang til visse af univer¬si-teternes kandidatuddannelser. Dette gælder således for kandidatuddannelsen i Læring og Forandringsprocesser på Aalborg Universitet, hvor denne artikels empiri er genereret fra. Artiklen fremlægger resultaterne af en undersøgelse af, hvordan studerende med forskellige uddannelsesbaggrunde må kæmpe om at definere sig selv og medstuderende som akademikere. Artiklens hovedbegreber er taget fra Pierre Bourdieus praktikteori (Bourdieu, 1996; 1997. Det empiriske materiale består af interviews med otte studerende fra samme årgang på kandidatuddannelsen i Læring og Forandringsprocesser. Materialet er bearbejdet ud fra et Bourdieuinspireret, relationelt blik og er kondenseret ned til fremtrædende træk ved forskelligartede strategier. Artiklen viser eksempler på fire studiestrategier, der relaterer sig til, hvordan man som studerende forholder sig til det at arbejde ”akademisk”: En oprørsstrategi der går mod forestillingen om den dominerende universitetskultur ; en strategi der i udgangspunktet ønsker at inkludere og anerkende andre strategier, men med en oplevelse af at motivationen gradvist forsvinder ; en strategi hvor den studerende aktivt afviser og undgår samarbejde med studerende med bestemte uddannel¬ses¬baggrunde, og endelig en kulturelt opadgående strategi der gradvis er lykkedes med at aflæse den ”akademiske kode". The number of students entering higher education since the Second World War has grown dramatically. As a consequence, students from University Colleges are now given admittance to certain master programmes at the established universities. This article presents the results of a study of how students with different educational backgrounds struggle to define themselves and their fellow students as academics.  In this study we focus on

    Sales, Célia Md; Neves, Inês Td; Alves, Paula G; Ashworth, Mark

    2017-11-22

    There is increasing interest in individualized patient-reported outcome measures (I-PROMS), where patients themselves indicate the specific problems they want to address in therapy and these problems are used as items within the outcome measurement tool. This paper examined the extent to which 279 items reported in an I-PROM (PSYCHLOPS) added qualitative information which was not captured by two well-established outcome measures (CORE-OM and PHQ-9). Comparison of items was only conducted for patients scoring above the "caseness" threshold on the standardized measures. 107 patients were participating in therapy within addiction and general psychiatric clinical settings. Almost every patient (95%) reported at least one item whose content was not covered by PHQ-9, and 71% reported at least one item not covered by CORE-OM. Results demonstrate the relevance of individualized outcome assessment for capturing data describing the issues of greatest concern to patients, as nomothetic measures do not always seem to capture the whole story. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    Debarati Paul

    Full Text Available Oligotropha carboxidovorans OM5 T. (DSM 1227, ATCC 49405 is a chemolithoautotrophic bacterium able to utilize CO and H(2 to derive energy for fixation of CO(2. Thus, it is capable of growth using syngas, which is a mixture of varying amounts of CO and H(2 generated by organic waste gasification. O. carboxidovorans is capable also of heterotrophic growth in standard bacteriologic media. Here we characterize how the O. carboxidovorans proteome adapts to different lifestyles of chemolithoautotrophy and heterotrophy. Fatty acid methyl ester (FAME analysis of O. carboxidovorans grown with acetate or with syngas showed that the bacterium changes membrane fatty acid composition. Quantitative shotgun proteomic analysis of O. carboxidovorans grown in the presence of acetate and syngas showed production of proteins encoded on the megaplasmid for assimilating CO and H(2 as well as proteins encoded on the chromosome that might have contributed to fatty acid and acetate metabolism. We found that adaptation to chemolithoautotrophic growth involved adaptations in cell envelope, oxidative homeostasis, and metabolic pathways such as glyoxylate shunt and amino acid/cofactor biosynthetic enzymes.

    Full Text Available Systemteoretisk medieforskning rejser spørgsmålet om, hvorvidt massemedierne udgør en samlet institution, eller om medierne, i kraft af deres indbyrdes forskelle, skal betragtes uafhængigt af hinanden. Ved at indskrive medierne i en generel samfundsteori fremstiller systemteorien medierne som et autonomt funktionssystem. Denne bestræbelse kommer tydeligst til udtryk i identifikationen af en fælles kode for massemediernes system. Med udgangspunkt i Niklas Luhmanns medieteori foretager nærværende artikel en kritisk gennemgang af den systemteoretiske medieforsknings kodediskussion. Første del præsenterer kort systemteoriens kodebegreb og Luhmanns bestemmelse af mediesystemet som organiseret omkring koden information. Den midterste del gennemgår en række alternative forslag til denne kodedefinition, hvilket illustrerer omfanget, men også nogle af begrænsningerne, ved systemteoretisk medieforskning. Sidste del foretager en kritisk diskussion af systemteoriens kodeproblematik og viser, hvordan en ensidig kodefokusering står i vejen for en fortsat udforskning af vilkårene for mediesystemets udvikling og autonomi.Systems theoretical media research raises the question whether the mass media constitute a unified institution, or whether the media, due to their internal differences, should be considered individually and independent of each other. By inscribing the media in a general social theory, systems theory conceptualises the media as an autonomous functional system. This intention is most clearly illustrated by the efforts to identify a shared code for the entire media system. Based on the media theory of Niklas Luhmann, this paper offers a critical presentation of the code discussion within systems theoretical media research. The first part of the paper briefly introduces the systems theoretical notion of a code as well as Luhmann’s definition of the media system as organised and regulated by the code of information.

    NOD1 has important roles in innate immunity as sensor of microbial components derived from bacterial peptidoglycan. In this study, we identified genes encoding components of the NOD1 signaling pathway, including NOD1 (OmNOD1) and RIP2 (OmRIP2) from rainbow trout, Oncorhynchus mykiss, and investigated whether OmNOD1 has immunomodulating activity in a rainbow trout hepatoma cell line RTH-149 treated with NOD1-specific ligand (iE-DAP). The deduced amino acid sequence of OmNOD1 contained conserved CARD, NOD and LRR domains. Loss-of-function and gain-of-function experiments indicated that OmNOD1 is involved in the expression of pro-inflammatory cytokines. Silencing of OmNOD1 in RTH-149 cells treated with iE-DAP decreased the expression of IL-1β, IL-6, IL-8 and TNF-α. Conversely, overexpression of OmNOD1 resulted in up-regulation of IL-1β, IL-6, IL-8 and TNF-α expression. In addition, RIP2 inhibitor (gefitinib) significantly decreased the expression of these pro-inflammatory cytokines induced by iE-DAP in RTH-149 cells. These findings highlight the important role of NOD1 signaling pathway in fish in eliciting innate immune response. Copyright © 2016 Elsevier Ltd. All rights reserved.

  19. A comparison of observed extreme water levels at the German Bight elaborated through an extreme value analysis (EVA) with extremes derived from a regionally coupled ocean-atmospheric climate model (MPI-OM)

    2017-04-01

    As a consequence of climate change atmospheric and oceanographic extremes and their potential impacts on coastal regions are of growing concern for governmental authorities responsible for the transportation infrastructure. Highest risks for shipping as well as for rail and road traffic originate from combined effects of extremes of storm surges and heavy rainfall which sometimes lead to insufficient dewatering of inland waterways. The German Ministry of Transport and digital Infrastructure therefore has tasked its Network of Experts to investigate the possible evolutions of extreme threats for low lands and especially for Kiel Canal, which is an important shortcut for shipping between the North and Baltic Seas. In this study we present results of a comparison of an Extreme Value Analysis (EVA) carried out on gauge observations and values derived from a coupled Regional Ocean-Atmosphere Climate Model (MPI-OM). High water levels at the coasts of the North and Baltic Seas are one of the most important hazards which increase the risk of flooding of the low-lying land and prevents such areas from an adequate dewatering. In this study changes in the intensity (magnitude of the extremes) and duration of extreme water levels (above a selected threshold) are investigated for several gauge stations with data partly reaching back to 1843. Different methods are used for the extreme value statistics, (1) a stationary general Pareto distribution (GPD) model as well as (2) an instationary statistical model for better reproduction of the impact of climate change. Most gauge stations show an increase of the mean water level of about 1-2 mm/year, with a stronger increase of the highest water levels and a decrease (or lower increase) of the lowest water levels. Also, the duration of possible dewatering time intervals for the Kiel-Canal was analysed. The results for the historical gauge station observations are compared to the statistics of modelled water levels from the coupled

    The investigation of physical properties of uranium and plutonium mixed oxide (MOX) fuels is important for the development of fast reactor fuels. It is well known that MOX is a nonstoichiometric oxide, and the physical properties change drastically with the Oxygen-to-Metal (O/M) ratio. A control technique for O/M ratio was established for measurements of high temperature properties of uranium and plutonium mixed oxide fuels. Sintering behavior, thermal expansion and O/M change of (U{sub 0.7}Pu{sub 0.3})O{sub 2.00} and (U{sub 0.7}Pu{sub 0.3})O{sub 1.99} were investigated in PO{sub 2}-controlled atmosphere which was controlled by H{sub 2}/H{sub 2}O gas system. Sintering behavior changed drastically with O/M ratio, and shrinkage of (U{sub 0.7}Pu{sub 0.3})O{sub 2.00} was faster and more advanced at lower temperatures as compared with (U{sub 0.7}Pu{sub 0.3})O{sub 1.99}. Thermal expansion was observed to be slightly increased with decreasing O/M ratio. (authors)

    Identificar inadequações nutricionais em segmentos específicos da população jovem pode oferecer subsídios para intervenção em saúde pública. O estudo analisou o estado nutricional antropométrico em amostra de adolescentes escolares de uma região brasileira de baixo desenvolvimento econômico. A amostra foi constituída por 1.538 sujeitos, com idades entre 15 e 18 anos, sendo 1.036 moças e 502 rapazes. O estado nutricional antropométrico foi identificado mediante medidas de estatura e cálculo do índice de massa corporal (IMC. As comparações estatísticas foram estabelecidas com base nas correspondentes distribuições de percentis da referência proposta pela Organização Mundial da Saúde-2007 (OMS-2007. Os resultados encontrados mostraram que, em ambos os sexos, as distribuições de percentis equivalentes aos valores de estatura e IMC foram estatisticamente diferentes da referência OMS-2007. Foram identificadas elevadas proporções de adolescentes com baixa estatura ( 90 Percentil. Portanto, mesmo sendo uma região de baixo desenvolvimento econômico e com um dos mais baixos indicadores sociais do país, o excesso de peso corporal foi um importante problema associado ao estado nutricional. A elevada proporção de sobrepeso/obesidade alerta para a necessidade de implementar políticas públicas direcionadas às práticas de alimentação saudável e atividade física.

    OMS'05 is the first international conference wholly dedicated to optical microsystems. It was organized by the European Optical Society (EOS) in the frame of its international topical meeting activity and was held in Italy, September 2005, amidst the wonderful scenery of the Island of Capri. A possible definition of an optical microsystem is a complex system, able to perform one or more sensing and actuation functions, where optical devices are integrated in a smart way with electronic, mechanical and sensing components by taking advantage of the progress in micro- and nano-technologies. The increasing interest in this field arises from the expected applications that would significantly improve the quality of life. The list of possibilities offered by the optical microsystem enabling technologies is very long and seems to increase day by day. We are not only thinking about the next generation of optical telecommunication networks and computers, but also about low-cost, compact microsystems for environmental monitoring, in order to improve safety in the avionic and automotive fields, medical diagnostics and proteomic/genomic studies, or just finding general applications in several industrial fields. The goal of the conference was to involve scientists and young researchers from the main public and private laboratories, giving them the opportunity to present new scientific results and compare their know-how in the exciting and emerging field of optical microsystems. We believe that we succeeded in this. More than 200 scientists from all over the world attended the conference. We had more than 100 oral presentations and approximately 20 from the keynote lectures and invited speeches. It was an opportunity to define the most recent progress carried out in the field and to outline the possible road-map leading to the expected results in the industrial and social fields. We strongly believe that research and technology are closely interconnected at present and cannot

    Objective To create a literature review between 2011 and June 1, 2015, on advances in otitis media (OM) epidemiology and diagnosis (including relevant audiology studies). Data Sources Electronic search engines (PubMed, EMBASE, and Cochrane Library) with a predefined search strategy. Review Methods Articles with appropriate epidemiologic methodology for OM, including acute mastoiditis and eustachian tube dysfunction. Items included OM worldwide and in high-risk populations, OM-related hearing loss, news in OM diagnostics, prenatal risk factors and comorbidities, postnatal risk factors, genetics, microbiological epidemiology, guidelines, and quality of life. Conclusions Diagnostic evidence and genetic studies are increasing; guidelines are introduced worldwide; and there is evidence of benefit of pneumococcal conjugate vaccines. New risk factors and comordities are identified in the study period, and quality of life is affected in children and their families. Implications for Practice Chronic suppurative OM occurs worldwide and contributes to lifelong hearing loss. Uniform definitions are still lacking and should be provided. An association between HIV and chronic suppurative OM has been found. Tympanometry is recommended for diagnosis, with or without pneumatic otoscopy. Video otoscopy, algorithms, and validated questionnaires may assist clinicians. Childhood obesity is associated with OM. Heritability accounts for 20% to 50% of OM diagnoses. OM-prone children seem to produce weaker immunologic responses to pneumococcal conjugate vaccines. Clinicians tend to individualize treatment without adhering to guidelines.

    Substantial amounts of organic matter (OM) from terrestrial ecosystems are buried as sediments in inland waters. It is still unclear to what extent this OM constitutes a sink of carbon, and how much of it is returned to the atmosphere upon mineralization to carbon dioxide (CO2). The construction of reservoirs affects the carbon cycle by increasing OM sedimentation at the regional scale. In this study we determine the OM mineralization in the sediment of three zones (river, transition, and dam) of a tropical hydroelectric reservoir in Brazil as well as identify the composition of the carbon pool available for mineralization. We measured sediment organic carbon mineralization rates and related them to the composition of the OM, bacterial abundance and pCO2 of the surface water of the reservoir. Terrestrial OM was an important substrate for the mineralization. In the river and transition zones most of the OM was allochthonous (56 and 48%, respectively) while the dam zone had the lowest allochthonous contribution (7%). The highest mineralization rates were found in the transition zone (154.80 ± 33.50 mg C m(-) (2) d(-) (1)) and the lowest in the dam (51.60 ± 26.80 mg C m(-) (2) d(-) (1)). Moreover, mineralization rates were significantly related to bacterial abundance (r (2) = 0.50, p hydroelectric reservoirs.

    2017-12-01

    Full Text Available Både fenomenologisk filosofi og teoriar om praktisk kunnskapsrasjonalitet formulerer erkjenningar som løftar fram det livsverdslege som materialgrunnlag for valid kunnskap. Det som særkjenner livsverda er det temporære, subjektive, fleirtydige og historisk situerte. Difor må, i følgje Edmund Husserl, ingen førpredikative premiss stå som kunnskapens udiskutable grunn. Han oppfordrar oss til å stille spørsmål ved tradisjonar som er så integrerte i kulturen at vi oppfattar dei som opphavelege. I ein pedagogisk samanheng er det aktuelt å undersøke om den sterke representasjonen av teoretisk pensum i grunnskulen er etablert i oss som eit dogme vi ikkje stiller spørsmål ved. For når vi spør kva elevgrupper som lir mest under situasjonen, er det tilsynelatande opplagte svaret at det er dei elevgruppene som ikkje «meistrar» teorien. Men finst det vinnarar i eit kunnskaps-udemokratisk system? Er ikkje alle som ikkje får tilgang til den rike praksiskunnskapen taparar? I denne artikkelen brukar eg fenomenologisk filosofi til å argumentere for ei pensumfornying der den tradisjonelt nedvurderte praksiskunnskapen blir gitt ein jamstilt plass. Med i analysen har eg refleksjonane til to ungdomar som begge går på ei yrkesfagleg linje i Noreg.

    Oxygen chemical diffusion in PuO 2-x was investigated in the temperature range of 1473-1873 K by thermogravimetry as functions of oxygen-to-metal (O/M) ratios and temperatures. The oxygen chemical diffusion coefficients, D were determined assuming that the reduction curves were dominated by a diffusion process. The O/M ratio and Pu content dependence on the chemical diffusion coefficients were evaluated. The chemical diffusion coefficient had its minimum value at around O/M=1.98 and decreased with increasing Pu content in (U,Pu)O 2-x . The self-diffusion coefficients were evaluated. A model for describing the relationship among O/M ratio, oxygen chemical diffusion, and self-diffusion was proposed based on defect chemistry. (copyright 2012 WILEY-VCH Verlag GmbH and Co.

    Full Text Available Substantial amounts of organic matter (OM from terrestrial ecosystems are buried as sediments in inland waters. It is still unclear to what extent this OM constitutes a sink of carbon, and how much of it is returned to the atmosphere upon mineralization to carbon dioxide (CO2. The construction of reservoirs affects the carbon cycle by increasing OM sedimentation at the regional scale. In this study we determine the OM mineralization in the sediment of three zones (river, transition and dam of a tropical hydroelectric reservoir in Brazil as well as identify the composition of the carbon pool available for mineralization. We measured sediment OC mineralization rates and related them to the composition of the OM, bacterial abundance and pCO2 of the surface water of the reservoir. Terrestrial OM was an important substrate for the mineralization. In the river and transition zones most of the OM was allochthonous (56 % and 48 %, respectively while the dam zone had the lowest allochthonous contribution (7 %. The highest mineralization rates were found in the transition zone (154.80 ± 33.50 mg C m-2 d-1 and the lowest in the dam (51.60 ± 26.80 mg C m-2 d-1. Moreover, mineralization rates were significantly related to bacterial abundance (r2 = 0.50, p < 0.001 and pCO2 in the surface water of the reservoir (r2 = 0.73, p < 0.001. The results indicate that allochthonous OM has different contributions to sediment mineralization in the three zones of the reservoir. Further, the sediment mineralization, mediated by heterotrophic bacteria metabolism, significantly contributes to CO2 supersaturation in the water column, resulting in higher pCO2 in the river and transition zones in comparison with the dam zone, affecting greenhouse gas emission estimations from hydroelectric reservoirs.

    Soil organic matter (SOM) protection and long-term accumulation are controlled by adsorption to mineral surfaces in different ways, depending on its molecular structure and pedo-climatic conditions. Iron (Fe) oxides are known to be key regulators of the soil carbon (C) cycle, and Fe speciation in soils is highly dependent on environmental conditions and chemical interactions with SOM. However, the molecular structure and hydrolysis of Fe species formed in association with SOM is still poorly described. We hypothesize the existence of two pools of Fe which interact with SOM: mononuclear Fe(III)-SOM complexes and precipitated Fe(III) hydroxides. To verify our hypothesis, we investigated the interactions between Fe(III) and physically isolated soil fractions by means of batch experiments at pH 7. Specifically, we examined the fine silt plus clay (FSi+C) fraction, obtained by ultrasonic dispersion and wet sieving. The soil samples spanned several land uses, including coniferous forest (CFS), grassland (GS), technosols (TS) and agricultural (AS) soils. Solid phase products and supernatants were analyzed for C and Fe content. X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) analysis were also performed. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was used to assess the main C functional groups involved in C complexation and desorption experiments. Preliminary linear combination fitting (LCF) of Fe K-edge extended X-ray absorption fine structure (EXAFS) spectra suggested the formation of ferrihydrite-like polymeric Fe(III) oxides in reacted CFS and GS samples, with higher C and Fe concentration. Conversely, mononuclear Fe(III) OM complexes dominated the speciation for TS and AS samples, characterized by lower C and Fe concentration, inhibiting the hydrolysis and polymerization of Fe (III). This approach will help revealing the mechanisms by which SOM pools can control Fe(III) speciation, and will elucidate how both Fe(III)-OM

    This report describes the Airline Fleet, Route, and Schedule Optimization Model (AFRS-OM) that is designed to provide insights into airline decision-making with regards to markets served, schedule of flights on these markets, the type of aircraft assigned to each scheduled flight, load factors, airfares, and airline profits. The main inputs to the model are hedged fuel prices, airport capacity limits, and candidate markets. Embedded in the model are aircraft performance and associated cost factors, and willingness-to-pay (i.e. demand vs. airfare curves). Case studies demonstrate the application of the model for analysis of the effects of increased capacity and changes in operating costs (e.g. fuel prices). Although there are differences between airports (due to differences in the magnitude of travel demand and sensitivity to airfare), the system is more sensitive to changes in fuel prices than capacity. Further, the benefits of modernization in the form of increased capacity could be undermined by increases in hedged fuel prices

    This work presents new results from gravity data analyses and interpretation within the Om Ali-Thelepte (OAT) basin, central Tunisia. It focuses on the hydrogeological implication, using several qualitative and quantitative techniques such as horizontal gradient, upward continuation and Euler deconvolution on boreholes log data, seismic reflection data and electrical conductivity measurements. The structures highlighted using the filtering techniques suggest that the Miocene aquifer of OAT basin is cut by four major fault systems that trend E-W, NE-SW, NW-SE and NNE-SSW. In addition, a NW-SE gravity model established shows the geometry of the Miocene sandstone reservoir and the Upper Cretaceous limestone rocks. Moreover, the superimposition of the electrical conductivity and the structural maps indicates that the low conductivity values of sampled water from boreholes are located around main faults.

    Toll like receptor 2 (TLR2) signaling can regulate the pathogenesis of otitis media (OM). However, the precise role of TLR2 signaling in OM has not been clarified due to the lack of an optimal animal model. Peptidoglycan-polysaccharide (PGPS) of the bacterial cell wall can induce inflammation by activating the TLR2 signaling. This study aimed at examining the pathogenic characteristics of OM induced by PGPS in Tlr2(-/-) mice, and the potential therapeutic effect of sodium aescinate (SA) in this model. Wild-type (WT) and Tlr2(-/-) mice were inoculated with streptococcal PGPS into their middle ears (MEs) and treated intravenously with vehicle or SA daily beginning at 3days prior to PGPS for 6 consecutive days. The pathologic changes of individual mice were evaluated longitudinally. In comparison with WT mice, Tlr2(-/-) mice were susceptible to PGPS-induced OM. Tlr2(-/-) mice displayed greater hearing loss, tympanic membrane damage, ME mucosal thickening, longer inflammation state, cilia and goblet cell loss. SA-treatment decreased neutrophil infiltration, modulated TLR2-related gene expression and improved ciliary organization. PGPS induced a relatively stable OM in Tlr2(-/-) mice, providing a new model for OM research. Treatment with SA mitigated the pathogenic damage in the ME and may be valuable for intervention of OM.

    Full Text Available Inside the talayotic complex known as So n'Oms, in the municipal area of Palma (Mallorca, Balearic Islands, there is a sanctuary excavated in the sixties which produced an ample series of thin walled pottery that were dedicated as offerings to the gods. All the material found can be dated between 20-10 a.C.-. and 50 d.C. It is so well preserved that it has been possible to recognise and determine decoration and paste and, therefore, to reach to the conclusion that most of them belongs to production centers situated in Mallorca and Ibiza (from this last almost the 70%. There are, also, italic and betican productions.Dentro del conjunto talayótico conocido como So n'Oms, situado en el término municipal de Palma (Mallorca, islas Baleares, existe un santuario excavado en la década de los sesenta, que proporcionó un extenso lote de cerámica de paredes finas, depositadas allí como ofrenda. Los materiales pueden situarse entre los años 20/10 a.C. y 50 de nuestra era. Destaca su buen estado de conservación, que ha permitido un reconocimiento minucioso de pastas y decoraciones, habiéndose podido atribuir una gran parte de las piezas a centros productores de Mallorca y sobre todo —más del 70 %— de Ibiza. También se han localizado vasos héticos e itálicos.

  11. Towards explaining excess CO2 production in wetlands - the roles of solid and dissolved organic matter as electron acceptors and of substrate quality

    To understand carbon storage in water logged, anaerobic peatlands, factors controlling mineralization have been studied for decades. Temperature, substrate quality, water table position and the availability of electron acceptors for oxidation of organic carbon have been identified as major factors. However, many studies reported an excess carbon dioxide (CO2) production over methane (CH4) that cannot be explained by available electron acceptors, and peat soils did not reach strictly methanogenic conditions (i.e., a stoichiometric formation ratio of 1:1 of CO2 to CH4). It has been hypothesized that peat organic matter (OM) provides a previously unrecognized electron acceptor for microbial respiration, elevating CO2 to CH4 ratios. Microbial reduction of dissolved OM has been shown in the mid 90's, but only recently mediated electrochemical techniques opened the possibility to access stocks and changes in electron accepting capacities (EAC) of OM in dissolved and solid form. While it was shown that the EAC of OM follows redox cycles of microbial reduction and O2 reoxidation, changes in the EAC of OM were so far not related quantitatively to CO2 production. We therefore tested if CO2 production in anoxic peat incubations is balanced by the consumption of electron acceptors if EAC of OM is included. We set up anoxic incubations with peat and monitored production of CO2 and CH4, and changes in EAC of OM in the dissolved and solid phase over time. Interestingly, in all incubations, the EAC of dissolved OM was poorly related to CO2 and CH4 production. Instead, dissolved OM was rapidly reduced at the onset of the incubations and thereafter remained in reduced form. In contrast, the decrease in the EAC of particulate (i.e. non-dissolved) OM was closely linked to the observed production of non-methanogenic CO2. Thereby, the total EAC of the solid OM pool by far exceeded the EAC of the dissolved OM pool. Over the course of eight week incubations, measured decreases in the EAC

    Given the high salinity, prevailing annual high temperatures, and ultra-oligotrophic conditions in the Red Sea isolation and characterization of important microbial groups thriving in this environment is important in understanding the ecological significance and metabolic capabilities of these communities. By using a high-­throughput cultivation technique in natural seawater amended with minute amounts of nutrients, members of the rare biosphere (PS1), methylotrophic Betaproteobacteria (OM43), and the ubiquitous and abundant SAR11 group (Pelagibacterales), were isolated in pure culture. Phylogenetic analyses of Red Sea isolates along with comparative genomics with close representatives from disparate provinces revealed ecotypes and genomic differentiation among the groups. Firstly, the PS1 alphaproteobacterial clade was found to be present in very low abundance in several metagenomic datasets form divergent environments. While strain RS24 (Red Sea) harbored genomic islands involved in polymer degradation, IMCC14465 (East (Japan) Sea) contained unique genes for degradation of aromatic compounds. Secondly, methylotrophic OM43 bacteria from the Red Sea (F5, G12 and H7) showed higher similarities with KB13 isolate from Hawaii, forming a ‘H-­RS’ (Hawaii-­Red Sea) cluster separate from HTCC2181 (Oregon isolate). HTCC2181 members were shown to prevail in cold, productive coastal environments and had an nqrA-­F system for energy generation by sodium motive force. On the contrary, H-­RS cluster members may be better adapted to warm and oligotrophic environments, and seem to generate energy by using a proton-­translocating NADH:Quinone oxidoreductase (complex I; nuoA-­N subunits). Moreover, F5, G12, and H7 had unique proteins related to resistance to UV, temperature and salinity, in addition to a heavy metal ‘resistance island’ as adaptive traits to cope with the environmental conditions in the Red Sea. Finally, description of the Red Sea Pelagibacterales
