2012-07-02

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.

Mastocitosis sistémica: repercusión ósea

Directory of Open Access Journals (Sweden)

Francisco R. Spivacow

2012-06-01

Full Text Available La mastocitosis sistémica es una enfermedad caracterizada por acumulación de mastocitos en varios órganos, de los cuales el más afectado es la piel. La repercusión ósea de esta enfermedad es poco frecuente y en general se la asocia al desarrollo de osteoporosis secundaria con o sin fracturas óseas. Se presentan tres pacientes con lesiones características en piel de mastocitosis y diferentes manifestaciones óseas; el primer caso es una mujer de 51 años en la que se observó una variante esclerosante muy poco frecuente, con densitometría ósea en valores normales-altos y aumento de la densidad ósea observada en varias vértebras por radiografías. Una punción-biopsia de cresta ilíaca confirmó el compromiso óseo de su enfermedad de base. El segundo caso fue una mujer de 57 años que mostró signos característicos de mastocitosis sistémica con diarreas, gastritis, flushes y reacciones cutáneas particulares ante exposición a alérgenos. Se observó además grave disminución de la densidad mineral ósea tanto en columna lumbar como en cuello de fémur con parámetros bioquímicos de aumento de la resorción ósea, por lo que fue necesario tratarla con bisfosfonatos. La tercera paciente, de 67 años de edad, presentó varias fracturas vertebrales, con densitometría ósea levemente disminuida. En esta última paciente se constató una hiperplaquetosis con diagnóstico histológico de trombocitemia esencial, cuadro que suele asociarse a la mastocitosis sistémica. En definitiva, se presentan y discuten tres variantes óseas diferentes de mastocitosis sistémica.

Um olhar sistêmico sobre a crise norte-americana

Directory of Open Access Journals (Sweden)

CHRISTIAN CARVALHO GANZERT

Full Text Available RESUMO No contexto contemporâneo, a economia global pode ser descrita como um sistema baseado em agentes que, quando associados, manifestam seus próprios meios e fins. A crise das hipotecas subprime nos Estados Unidos é um bom exemplo das implicações desse tipo de relacionamento. Ela está diretamente relacionada a poderosos laços de realimentação, compostos por uma série de variáveis que amplificaram o fato de as famílias americanas terem se endividado em ritmo maior do que a sua distribuição de riqueza, prejudicada pela externalização da produção. Há atualmente uma nova estrutura na economia internacional, em que as ex-nações subdesenvolvidas estão mais bem posicionadas no cenário macroeconômico e têm maior poder do que antes - uma consequência do necessário rearranjo sistêmico. Diante dessa complexa dinâmica, a função de inteligência que deveria controlar e garantir a estabilidade sistêmica falhou em perceber a dinâmica e os impactos da nova cultura atrelada ao comportamento do capital contemporâneo, para evitar a perda da hegemonia. Observando-se ex post facto, por meio de um enfoque sistêmico, a crise econômica americana pode ser definida como tendo suas raízes nas premissas de todo o arcabouço cultural da globalização que acabou por conduzir à externalização da produção. Assim, o contexto sistêmico desta análise aponta que a cultura, como importante gerador e amplificador, deve ser o principal foco dos intentos de análise do atual contexto socioeconômico global.

Full Text Available OBJETIVO. A osteopenia em pacientes com esclerodermia sistêmica foi descrita, radiologicamente, em mãos e, por densidade óssea, no terço proximal e distal do rádio. A redução da massa óssea, nesses pacientes, tem sido atribuída à isquemia, imobilização e à menopausa precoce. O objetivo deste estudo é analisar a densidade óssea na coluna, região proximal do fêmur e corpo todo de pacientes com esclerodermia sistêmica. PACIENTES E MÉTODO. Foram examinadas 25 pacientes caucasóides, sem outras condições que pudessem afetar o metabolismo ósseo. A média de idade das pacientes foi de 48 ± 12 anos, e o tempo de doença, de 7 ± 7 anos; 13 estavam na pós-menopausa há 8 ± 8 anos. A medida de massa óssea foi realizada na coluna, região proximal do fêmur e corpo todo, utilizando-se densitômetro de dupla emissão com fonte de raios X (Lunar - modelo DPX. RESULTADOS. Não houve diferença estatisticamente significante na densidade óssea das regiões avaliadas nas pacientes com esclerodermia sistêmica e as mulheres-controle pareadas para a idade, peso, altura e anos de menopausa. A densidade óssea das pacientes com forma limitada não foi diferente daquelas com a forma difusa. Pacientes com calcinose apresentaram menor densidade óssea na região proximal do fêmur que aquelas sem calcinose. CONCLUSÕES. Os autores concluíram que pacientes com esclerodermia sistêmica não apresentam perda de massa óssea. Portanto, a esclerodermia não é um fator de risco para o desenvolvimento de osteoporose generalizada.

Selective hydrogenation of halogenated arenes using porous manganese oxide (OMS-2) and platinum supported OMS-2 catalysts.

Science.gov (United States)

McManus, Iain J; Daly, Helen; Manyar, Haresh G; Taylor, S F Rebecca; Thompson, Jillian M; Hardacre, Christopher

2016-07-04

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.

Instrumentelt turistspråk eller interkulturell dannelse? Om fremmedspråkfagets formål i dag og frem mot 2030

Directory of Open Access Journals (Sweden)

Eva Thue Vold

2014-09-01

Full Text Available Fremmedspråkfaget har lenge hatt et todelt formål: Det skal ha en nytteverdi, først og fremst i form av kommunikative ferdigheter, og det skal ha en allmenndannende funksjon, bl.a. gjennom tilegnelse av kunnskap om kultur og samfunn i målspråksområdet. Fra og med læreplanen for fremmedspråk i Kunnskapsløftet (2006 er det også tydelig uttrykt at dannelsesdimensjonen omfatter utvikling av interkulturell kompetanse. Denne artikkelen drøfter hvordan fagets todelte formål vil kunne forstås og realiseres i fremmedspråksundervisningen fram mot 2030. Drøftingen tar utgangspunkt i en analyse av dagens situasjon, der trenden med å stykke opp lærestoffet i håndterbare enheter og å vektlegge sterkest det som kan måles mest presist, kan gjøre at ikke-målbar kompetanse som interkulturell dannelse får en relativt svak posisjon. Det argumenteres for at pågående endringer i samfunnsutviklingen og i europeisk utdanningspolitikk vil kunne åpne for en jevnere balanse mellom nytte- og dannelsesperspektivet i faget i fremtiden. Blant disse endringene er 1 en dreining mot et mer holistisk kunnskapssyn, 2 en stadig økende heterogenitet i elevmassen, 3 større bredde i fremmedspråkstilbudet og 4 et økt fokus på flerspråklighet. Artikkelen ser nærmere på disse fire endringsprosessene og diskuterer på hvilken måte de kan og bør påvirke fortolkningen av fremmedspråkfagets todelte formål i årene som kommer.

Sociología de la intervención: orientación sistémica contextual

Directory of Open Access Journals (Sweden)

Aldo Mascareño

2011-01-01

Full Text Available La diferenciación funcional de la sociedad moderna indica la autonomía y clausura operativa de sistemas sociales. Esta condición es compensada por mecanismos de acoplamiento estructural entre sistemas que permiten una coordinación social relativamente integrada. No obstante, ni conflictos, intervenciones o desdiferenciaciones sistémicas, como tampoco rendimientos sistémicos que afecten el entorno social como el riesgo ecológico o la pobreza son inusuales en la sociedad moderna. La pregunta de este artículo es bajo qué condiciones es posible la regulación sistémica para abrir vías de solución a estos problemas sin que ello implique una intervención autoritativa de sistemas sociales. Se explican e ilustran los principios de una intervención sistémica contextual como coordinación pragmática de intransparencias. La función de esta estrategia consiste en incrementar la contingencia del sistema a regular con ofertas comunicativas en el lenguaje del sistema; su prestación reside en el tratamiento social de los problemas diagnosticados.

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.

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.

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

OMS FDIR: Initial prototyping

Science.gov (United States)

Taylor, Eric W.; Hanson, Matthew A.

1990-01-01

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.

Perfil Sistêmico e Manifestações Bucais em Pacientes com Hipotireoidismo

Directory of Open Access Journals (Sweden)

Graziele Beanes da Silva Santos

2012-06-01

Full Text Available O hipotireoidismo é uma desordem endócrina, de natureza sistêmica caracterizada pela disfunção na glândula tireóide. Os hormônios tireoidianos T3 e T4 são necessários para suprir funções orgânicas normais do organismo. Desta forma, distúrbios na secreção de T3 e T4 podem estar associados a alterações no sistema estomatognático. Dentre essas alterações encontram-se hipoplasia condilar, atresia maxilar ou mandibular, hipodesenvolvimento da mandíbula, prognatismo maxilar, hipoplasia de esmalte e dentina, taurodontia e retardo na erupção dentária e no desenvolvimento radicular. Desta forma é imprescindível que o cirurgião dentista tenha conhecimento sobre as manifestações locais ou sistêmicas associadas a esta desordem endócrina. O objetivo deste artigo é abordar as alterações sistêmicas e bucais em pacientes acometidos pelo hipotireoidismo, bem como os cuidados e condutas terapêutica que podem ser adotados durante o tratamento odontológico. A coleta de dados foi realizada através da seleção de artigos publicados a cerca das manifestações bucais em pacientes acometidos por hipotireoidismo nos principais bancos de dados, Bireme, Medline e Scielo. O hipotireoidismo é uma patologia sistêmica comum, que ocasionalmente apresenta manifestações bucais e necessitam de cuidados especiais durante tratamentos odontológicos. A interação medicamentosa frente à pacientes em tratamento do hipotireoidismo também deve ser considerada, uma vez que medicações comumente prescritas na odontologia podem promover reações adversas. Desta forma, é imprescindível que o cirurgião-dentista tenha conhecimento sobre os procedimentos adequados na terapêutica de pacientes com essa síndrome.

Ten-year rollover of San Onofre inservice testing program for pumps and valves to OM-6 and OM-10

International Nuclear Information System (INIS)

Croy, P.A.; Fischetti, S.; Chiang, D.; Schofield, P.; Barney, D.

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

MÉTODOS: Foram estudados retrospectivamente 18 pacientes com diagnóstico de coloboma ocular matriculados no serviço de Visão Subnormal do Hospital São Geraldo da Universidade Federal de Minas Gerais (HSG - HCUFMG. Foram avaliados: sexo, idade, raça, história familiar de anomalias oculares, história gestacional, tipo de coloboma, localização, bilateralidade, presença de microftalmia ou anoftalmia, alterações oculares concomitantes, e associação com doenças sistêmicas e acuidade visual. RESULTADO: Dez (55,6% pacientes eram do sexo feminino, 15 (83,3% eram leucodérmicos. A idade variou de 4 a 57 anos, com média de 9,5 anos. Apenas 3 (16,7% apresentavam história familiar para coloboma. Todos apresentavam história gestacional negativa para qualquer intercorrência. Houve acometimento bilateral em 100% dos casos, com microftalmia presente em 6 (33,3% casos. O coloboma foi típico em 14 (77,8% pacientes, sendo o coloboma mais comum o retinocoroidal ocorrendo em 16 (88,9% pacientes. 50% dos pacientes apresentavam o coloboma como achado isolado, e a outra metade associado a alguma doença sistêmica. Em 14 (77,8% pacientes foi encontrado algum tipo de alteração ocular além do coloboma. CONCLUSÃO: O exame oftalmológico completo é muito importante tanto no diagnóstico quanto no prognóstico de pacientes com coloboma, visto que este pode estar associado a uma baixa visual importante, além de poder estar relacionados a diferentes anomalias ou síndromes.

Shuttle performance enhancements using an OMS payload bay kit

Science.gov (United States)

Templin, Kevin C.; Mallini, Charles J.

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.

Full Text Available  SAMMENDRAGI 1973 ble det påvist økt risiko for lunge- og nese-/bihulekreft blant norske nikkelverksarbeidere i en epidemiologiskundersøkelse fra Kreftregisteret. Analysene var basert på 48 lungekrefttilfeller, og man fant atrisikoen var høyest i den gruppen som hadde lengst ansettelse i roste-, smelte- og elektrolyseavdelingene.Tilsvarende funn var tidligere gjort blant nikkelarbeidere i andre land, og undersøkelsen vakte oppsikt fordiforhøyet risiko også ble funnet blant ansatte i elektrolysen. Senere analyser med spesifikke eksponeringsdatahar vist at kreftfaren er nært knyttet til eksponering for vannløselige nikkelformer. Nye data er nå blitt samletinn i forbindelse med en pasient-kontroll-undersøkelse basert på 213 tilfeller av lungekreft og 525 kontrollpersoner.På bakgrunn av opplysningene er relativ risiko regnet ut ved hjelp av regresjonsmodeller derfølgende faktorer var inkludert: total varighet av ansettelse ved bedriften, eller varighet av ansettelse i ulikeavdelinger, tidspunkt for førsteansettelse og røykevaner. Resultatene fra pasient-kontroll-analysen bekreftetfunnene fra 1973 når disse ble regnet om til relativ risiko, og tydet på at konklusjonene fra den gang varvalide selv om analysene var basert på færre arbeidstakere, kortere observasjonstid, en forenklet inndelingav arbeidstakerene i henhold til deres avdelingshistorikk, og manglende opplysninger om røykevanene.Grimsrud TK. Lung cancer among Norwegian nickel-refinery workers: Reappraisial ofa classical study. Nor J Epidemiol 2001; 11 (2: 171-176.  ENGLISH SUMMARYIn 1973, increased risk of cancer of the lung and nasal cavities was demonstrated among Norwegian nickelworkers in a study from The Cancer Registry of Norway (Kreftregisteret.

Full Text Available Introducción: La falla cardiaca, es un síndrome clínico habitualmente progresivo que con frecuencia comienza como disfunción sistólica ventricular izquierda y culmina con manifestaciones clínicas diversas de fallo de bomba y bajo gasto cardiaco hasta la muerte. Objetivo: Caracterizar los factores de riesgo que están asociados al desarrollo de disfunción sistólica ventricular izquierda y falla cardiaca secundaria como parte del espectro del síndrome de falla cardiaca en la población de Barranquilla-Colombia. Materiales y Métodos: Se realizó un estudio descriptivo de corte transversal con fuente secundaria de un estudio de salud global en la ciudad de Barranquilla-Colombia, en el que se hizo análisis univariado y bivariado para describir factores de riesgo asociados a la disfunción sistólica ventricular izquierda. Resultados: Se obtuvieron las prevalencias de cuatro factores de riesgo asociados al desarrollo de disfunción sistólica ventricular izquierda: hipertensión arterial 29.7%, obesidad 26.5%, hiperglucemia 4.6%, hipercolesterolemia 8.2% en pacientes mayores de 40 años los cuales tienen mayor riesgo. Discusión: Este estudio buscó llamar la atención sobre la disfunción sistólica ventricular izquierda, como una condición de descripción relativamente reciente y de potencial impacto en la salud de las poblaciones y los recursos de los sistemas de salud. Conclusiones: La prevalencia de los factores de riesgo para este estado pre-clínico podría llegar a ser alta y estos pacientes ameritarían, según recomendación de cierta evidencia, tamización para disfunción sistólica ventricular izquierda, así como estudios adicionales son requeridos.

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. The Ada Program also has the ability to reschedule all or part of the events.

Full Text Available Se detalla el origen de dos noveles heurísticas para el TSP simétrico, inspiradas en el pensamiento sistémico: Sacrificio Cortoplacista Adaptativo 2-opt (SCA_2opt y SCA_2_opt_r. Estas surgen del análisis sistémico de la regla de decisión Vecino más cercano, identificándosele el arquetipo "Soluciones contraproducentes". El SCA se basa en que el agente viajero renuncie en un momento dado a una ciudad inmediatamente cercana, y se traslade hacia la segunda ciudad más cercana disponible. A partir de ello, se continúa con la regla del vecino más cercano. Cada que se realiza el SCA (búsqueda global se efectúa una búsqueda local 2_opt. Considerando el binomio eficacia y eficiencia, las dos heurísticas se muestran prometedoras en comparación multicriterio contra 19 metaheurísticas.

2017-01-01

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

Non-Toxic Orbiter Maneuvering System (OMS) and Reaction Control System

Science.gov (United States)

Hurlbert, Eric A.; Nicholson, Leonard S. (Technical Monitor)

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

Jornalismo, redes sociais e movimentos de ocupação global: crise sistêmica na semiosfera contemporânea

Directory of Open Access Journals (Sweden)

Felipe de Oliveira

2014-06-01

Full Text Available O artigo reflete sobre tensões geradas ao jornalismo com a emergência das redes sociais nos processos de construção social da realidade. O foco são acontecimentos suscitados pelo movimento Indignados, na Espanha, em 2012, durante o protesto “25S”, cuja demanda era uma nova assembleia constituinte. O garçom Alberto Casillas roubou a cena ao enfrentar a truculência policial, produzindo intensa repercussão nas redes e chamando a atenção do jornalismo. São dois os principais pontos de vista que, cotejados, levam a uma síntese possível acerca desse momento de crise: 1 a forma como o jornalismo representa os acontecimentos; 2 possibilidades e implicações proporcionadas pelas redes nas dinâmicas mais amplas do jornalismo. O esforço reflexivo tem como base o conceito de semiose, de C. S. Peirce, e uma visão sistêmica inspirada na Semiótica da Cultura – especialmente em Yuri Lótman. Postula-se que na semiosfera contemporânea em que se desenrolam complexos processos de semiose disparados por acontecimentos da ordem da realidade caótica, o jornalismo seja tensionado a rever suas práticas, sob o risco de perder a legitimidade que alcançou ao longo da história como mediador que produz certo tipo de conhecimento.

Sociologias do Direito: historicismo, subjetivismo e teoria sistêmica

Directory of Open Access Journals (Sweden)

Marcelo Pereira de Mello

2005-11-01

Full Text Available O objetivo deste artigo é reconstituir criticamente o debate contemporâneo de duas das perspectivas mais proeminentes da Sociologia do Direito: o "historicismo racionalista", derivado dos estudos de Max Weber, e a teoria sistêmica de Niklas Luhmann e sua variação reflexiva em Gunther Teubner. Essas duas escolas sociológicas expressam perspectivas diferenciadas para a compreensão dos nexos entre o fenômeno jurídico e as relações sociais; a despeito de suas origens germânicas, influenciaram inúmeros pensadores na Inglaterra e nos EUA. De um lado, a perspectiva weberiana, inspiradora de uma infinidade de correntes empiristas, com enorme ascendência intelectual sobre a Sociologia anglo-americana, comprometida com a sistematização de informações recolhidas em fontes primárias, históricas e documentais; de outro lado, a combinação entre a teoria sistêmica de Luhmann e o conceito de "autopoiesis" tomado à Biologia, enseja uma vigorosa interpretação sociológica do Direito que, de maneira muito engenhosa, reconstrói os objetos do Direito e da Sociologia para explicar a natureza dos fenômenos sócio-jurídicos. No ensejo de discutirmos os modelos teóricos dessas perspectivas e testarmos-lhes os limites e as potencialidades para explicação dos problemas contemporâneos relativos ao Direito e à sociedade, explicitaremos as conexões entre as afirmações gerais dessas teorias e os pressupostos gerais de suas respectivas epistemologias.

Full Text Available O hipotireoidismo é uma desordem endócrina, de natureza sistêmica caracterizada pela disfunção na glândula tireóide. Os hormônios tireoidianos T3 e T4 são necessários para suprir funções orgânicas normais do organismo. Desta forma, distúrbios na secreção de T3 e T4 podem estar associados a alterações no sistema estomatognático. Dentre essas alterações encontram-se hipoplasia condilar, atresia maxilar ou mandibular, hipodesenvolvimento da mandíbula, prognatismo maxilar, hipoplasia de esmalte e dentina, taurodontia e retardo na erupção dentária e no desenvolvimento radicular. Desta forma é imprescindível que o cirurgião dentista tenha conhecimento sobre as manifestações locais ou sistêmicas associadas a esta desordem endócrina. O objetivo deste artigo é abordar as alterações sistêmicas e bucais em pacientes acometidos pelo hipotireoidismo, bem como os cuidados e condutas terapêutica que podem ser adotados durante o tratamento odontológico. A coleta de dados foi realizada através da seleção de artigos publicados a cerca das manifestações bucais em pacientes acometidos por hipotireoidismo nos principais bancos de dados, Bireme, Medline e Scielo. O hipotireoidismo é uma patologia sistêmica comum, que ocasionalmente apresenta manifestações bucais e necessitam de cuidados especiais durante tratamentos odontológicos. A interação medicamentosa frente à pacientes em tratamento do hipotireoidismo também deve ser considerada, uma vez que medicações comumente prescritas na odontologia podem promover reações adversas. Desta forma, é imprescindível que o cirurgião-dentista tenha conhecimento sobre os procedimentos adequados na terapêutica de pacientes com essa síndrome.El hipotiroidismo es un trastorno endocrino que se caracteriza por el carácter sistémico de la disfunción de la glándula tiroides.

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.

Variations in the OM/OC ratio of urban organic aerosol next to a major roadway.

Science.gov (United States)

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.

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

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.

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.

There is a need for integrating those techniques through a systemic productivity management model, and this is the main objective of this paper. Starting from a set of theoretical guidelines that represents the systemic productivity management model, a process was developed for its measurement using the Cambridge process approach.

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.

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.

Borg Kjerkegaard, Jonas; Bærentsen, Klaus B.

2015-01-01

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. Beslutningen om at deltage i eksperimenterne, og følge de eksperimentelle instrukser har betydning for deltagerne, og den fremlagte empiri viser, at deltagernes bevidste intentioner er...... kausalt effektive i forhold til de efterfølgende handlinger. Den "ubevidste" måde valgene træffes på i eksperimentalsituationen er en opfyldelse af de eksperimentelle instrukser. Eksperimenterne af Libet og efterfølgere viser sig alt i alt ikke at modbevise fri vilje. Analysen af eksperimenterne peger på...

A teoria/concepção sistêmica: uma perspectiva crítica na pedagogia

Directory of Open Access Journals (Sweden)

2006-11-01

Full Text Available ?Inicialmente pensado para ser uma resenha do livro Educação Física e sociedade, em que encontramos parte essencial da construção teórica da chamada concepção sistêmica de educação física, este artigo amplia seus limites e dialoga com algumas outras produções no âmbito desta que pretende ser uma ‘sociologia (sistêmica da educação física’. Nossas considerações se direcionam para aspectos epistemológicos, políticos e pedagógicos desta teoria. Argumentamos que: a ela aponta elementos metodológicos que contribuem com o discurso crítico em EF; b encontra-se atravessada tanto por pressupostos que identificam o discurso crítico quanto por aqueles que demarcam uma postura conservadora; c uma perspectiva sociológica com base na teoria dos sistemas possui fatores limitantes para o desenvolvimento de algo como uma uma ‘sociologia da EF’. PALAVRAS-CHAVE: concepção sistêmica, sociologia, educação física. The initial aim of this paper was to report the book Educação Física e sociedade,mainly the systemic conception of physical education. As this article enlarged its limits, it enclosed other productions in the field of “sociology of physical education” with the epistemological, political and pedagogical elements of this theory. We realized that: a it points out methodological elements which contribute to the critical discourse of physical education; b it presents characteristics of a critical discourse as well as a conservative attitude; c it presents a sociological perspective based on a systemic theory with restrictive elements to the development of a “sociology of physical education”. KEY WORDS: Systemic conception, sociology, physical education.

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.

Full Text Available JUSTIFICATIVA E OBJETIVOS: Devido à grande prevalência da hipertensão arterial sistêmica na população e a falta de consenso sobre que níveis pressóricos o anestesiologista deve aceitar para induzir uma anestesia para cirurgia eletiva, realizou-se uma revisão na literatura que trata da associação hipertensão arterial e anestesia. Considerando que a suspensão de uma cirurgia implica em gastos, o que torna a Medicina cada vez mais cara, e que, por outro lado, o ato anestésico deve ser realizado com a maior segurança possível, o objetivo desse trabalho foi analisar as evidências da literatura que possam nortear a prática clínica. CONTEÚDO: O artigo apresenta incidência e classificação da hipertensão arterial sistêmica além de relatar e comentar trabalhos relevantes que abordam a hipertensão arterial no paciente cirúrgico. CONCLUSÕES: Ainda não estão estabelecidos quais níveis máximos de pressão são compatíveis com uma cirurgia eletiva, sendo que, atualmente, os critérios para a suspensão da cirurgia no paciente hipertenso mal controlado são muito mais baseados em dados empíricos que em evidências. Existe uma tendência em postergar a cirurgia quando a PA é superior a 180/110 mmHg, mas cada caso deve ser analisado isoladamente, valorizando mais lesões em órgãos alvo que a pressão arterial propriamente dita.JUSTIFICATIVA Y OBJETIVOS: Debido a la grande superioridad de la hipertensión arterial sistémica en la población y la falta de acuerdo sobre que niveles presóricos el anestesiologista debe aceptar para inducir una anestesia para cirugía electiva, se realizó una revisión en la literatura que trata de la asociación hipertensión arterial y anestesia.

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.

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.

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.

Synthesis of Cation and Water Free Cryptomelane Type OMS-2 Cathode Materials: The Impact of Tunnel Water on Electrochemistry

2017-01-01

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.

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.

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.

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.

Liu, Guanglong; Liao, Shuijiao; Zhu, Duanwei; Cui, Jingzhen; Zhou, Wenbing

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.

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

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

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.

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

International Nuclear Information System (INIS)

Wilde, E.W.

2003-01-01

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)

Pranzatelli, Michael R; McGee, Nathan R; Tate, Elizabeth D

2018-04-12

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.

Influence of activated carbon preloading by EfOM fractions from treated wastewater on adsorption of pharmaceutically active compounds.

2016-05-01

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.

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.

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.

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).

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.

A Best Practice for Developing Availability Guarantee Language in Photovoltaic (PV) O&M Agreements.

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.

CSF neurofilament light chain is elevated in OMS (decreasing with immunotherapy) and other pediatric neuroinflammatory disorders.

2014-01-15

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.

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.

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

OM and A considerations in PLEx decision making for CANDUR reactors

International Nuclear Information System (INIS)

Azeez, S.; Olmstead, R.; Krishnan, V. S.; Ramakrichnan, T. K.; Kakaria, B. K.

2002-01-01

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

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.

Data from the Brazilian National Household Sample Survey (PNAD was used, incorporating information from the sampling plan. Logistic regression was used to obtain the odds ratio (OR as a measure of association between variables and the outcome. The prevalence of self-reported high blood pressure in Brazil was 20.9%: 21% in urban areas and 20.1% in rural areas (OR = 1.06. In both areas, the likelihood of reporting high blood pressure increased with age and women, former smokers, migrants and individuals with morbidities, non-white individuals and individuals with health insurance were more likely to report this disease. Also, in both rural and urban areas, prevalence of high blood pressure was lower among workers and decreased with increasing levels of schooling. All variables showed an association with self-reported high blood pressure in both rural and urban areas, but differences in magnitude were observed in relation to sex and age group. These differences could help justify the promotion of better access and intervention methods at prevention clinics for different population groups.Este artículo tiene por objetivo estimar las prevalencias de la hipertensión arterial sistémica autorreferida de adultos, en los ambientes urbano y rural de Brasil, e identificar posibles asociaciones, estratificadas por situación del domicilio.

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.

Full Text Available Los pacientes con diagnóstico de lupus eritematoso sistémico (LES presentan una elevada morbi-mortalidad asociada a las manifestaciones cardiopulmonares que se desarrollan durante la evolución de la enfermedad. En este sentido, se han descrito dos picos de incidencia de mortalidad de esta enfermedad inmunológica. El primer pico está relacionado a la actividad de la enfermedad y se observa durante los tres primeros años posteriores al diagnóstico. El segundo pico está relacionado principalmente a las complicaciones cardiopulmonares y se presenta entre los 4 y 20 años posteriores al diagnóstico. Si bien la mortalidad temprana ha disminuido gracias a un mayor conocimiento de la fisiopatología de la enfermedad y al uso de terapias inmunosupresoras, la mortalidad tardía presenta un aumento progresivo de su frecuencia a pesar del avance en el manejo terapéutico. El estudio de estas complicaciones se ha convertido en un tema de gran interés debido a su efecto negativo en el pronóstico de los pacientes que las presentan. Algunos estudios epidemiológicos sugieren que los pacientes con LES tienen un mayor riesgo cardiovascular al ser comparados con la población sana. En este sentido, se ha descrito que estos presentan un mayor riesgo de desarrollar eventos cardiovasculares (infarto agudo del miocardio, accidente cerebro vascular y enfermedad arterial periférica en comparación con la población general. De forma asociada, se ha objetivado que la presencia de manifestaciones pleuro-pulmonares (pleuritis lúpica, neumonitis, hemorragia pulmonar, embolismo pulmonar e hipertensión pulmonar aumenta la morbimortalidad de los pacientes con LES.

Herbart om oppdragelse, formbarhet og takt

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.

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.

Effects of the Bacterial Extract OM-85 on Phagocyte Functions and the Stress Response

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

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.

[Self-assessment of tasks and roles of occupational medicine service (OMS) nurses in the Polish system of workers' health protection].

Sakowski, Piotr

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.

New directions and challenges for the O&M committee

Energy Technology Data Exchange (ETDEWEB)

Pelletier, J.P.

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.

The Hygiene Hypothesis suggesting an inverse relationship between incidence of infections and the increase in atopic diseases in these countries, is one of the working hypothesis proposed to explain this trend.This study tested the efficacy and safety of oral administration of the bacterial lysate OM-85 (Broncho-Vaxom®, Broncho-Munal®, Ommunal®, Paxoral®, Vaxoral®, in the treatment of established AD in children.Children aged 6 months to 7 years, with confirmed AD diagnosis, were randomized in a double-blind, placebo-controlled trial to receive, in addition to conventional treatment with emollients and topical corticosteroids, 3.5mg of the bacterial extract OM-85 or placebo daily for 9 months. The primary end-point was the difference between groups in the occurrence of new flares (NF during the study period, evaluated by Hazard Ratio (HR derived from conditional Cox proportional hazard regression models accounting for repeated events.Among the 179 randomized children, 170 were analysed, 88 in the OM-85 and 82 in the placebo group. As expected most children in both treatment groups experienced at least 1 NF during the study period (75 (85% patients in the OM-85 group and 72 (88% in the placebo group. Patients treated with OM-85 as adjuvant therapy had significantly fewer and delayed NFs (HR of repeated flares = 0.80; 95% confidence interval (CI: 0.67-0.96, also when potential confounding factors, as family history of atopy and corticosteroids use, were taken into account (HR = 0.82; 95% CI: 0.69-0.98. No major side effect was reported, with comparable and good tolerability for OM-85 and placebo.Results show an adjuvant therapeutic effect of a well standardized bacterial lysate OM-85 on established AD.

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

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

Size-controlled synthesis and formation mechanism of manganese oxide OMS-2 nanowires under reflux conditions with KMnO4 and inorganic acids

Science.gov (United States)

Zhang, Qin; Cheng, Xiaodi; Qiu, Guohong; Liu, Fan; Feng, Xionghan

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.

Implementeringsforskning: vitenskap for forbedring av praksis

Full Text Available Medisinsk forskning har ført til store framskritt de siste tiårene. Det er investert mye mer ressurser på basalforskning og klinisk forskning enn på å utvikle og evaluere metoder for å sikre at pasientene får nytte av forskningen. Formålet med implementeringsforskning er å redusere gapet mellom forskning og praksis, ved å utvikle og evaluere tiltak som kan sikre at behandlingen som pasientene mottar er kunnskapsbasert, at den er omsorgsfull og av god kvalitet.I denne artikkelen gjør vi rede for hva implementering og implementeringsforskning er. Vi belyser historikken til denne unge vitenskapen, og illustrerer mangfoldet i de faglige tilnærmingene og begrepene som brukes om det å få forskning brukt i praksis. Det finnes en rekke teorier om endring av atferd, både på individnivå og på organisatorisk nivå. Teoriene er imidlertid i liten grad testet empirisk, særlig når det gjelder å endre atferd i helsetjenesten.Systematiske oversikter over metodisk gode studier er den beste kilden til informasjon om effekt av implementeringstiltak. The Cochrane Effective Practice and Organisation of Care Group (EPOC er en viktig kilde for slike oversikter. De systematiske oversiktene som er utarbeidet på dette feltet viser at passive dissemineringstiltak har begrenset effekt, mens mer aktive tiltak kan ha liten til moderat effekt.

Molecular cloning and functional characterization of peptidoglycan recognition protein OmPGRP-L2 from the rainbow trout, Oncorhynchus mykiss.

Science.gov (United States)

Jang, Ju Hye; Kim, Hyun; Cho, Ju Hyun

2017-10-01

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.

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.

Olsson, Monica; Teär Fahnehjelm, Kristina; Rydberg, Agneta; Ygge, Jan

2015-08-01

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.

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.

Competitividad Sistémica. Niveles analíticos para el fortalecimiento de sectores de actividad económica

Full Text Available Un desarrollo industrial exitoso no se logra meramente considerando la función de producción en el nivel microeconómico, o las condiciones macroeconómicas estables; sino también por la existencia de medidas específicas del gobierno y de organizaciones privadas de desarrollo, orientadas a fortalecer la competitividad de los sectores de actividad económica. Además, la capacidad de vincular las iniciativas, está en función de un conjunto de estructuras político- económicas y de factores socioculturales y patrones básicos de organización, que caracterizan el proceso sistémico de competitividad de cada país. Se concluye que existe una marcada desarticulación entre los niveles de competitividad sistémica; reflejada por una incoherencia entre las políticas de Estado, los requerimientos de sectores de actividad y el reflejo de la necesidad real de las comunidades cada vez más desprovistas de recursos. Se recomienda la necesidad de superar la ardua fase que representa establecer una economía de mercado dirigida a mejorar la condición de vida de la población; por lo que será importante facilitar procesos autónomos de búsqueda y aprendizaje significativos, para el desarrollo de la competitividad de los sectores de actividad económica latinoamericanos.

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.

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.

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.

Full Text Available Når det gjelder romanen Naustet av Jon Fosse er det ikke tvil om at det blant annet – og kanskje hovedsaklig – er „dette noko / skrifta berettar om“. Det er derfor denne romanen også kan kalles for en metaroman. Tematiseringen av skriveren og skriveprosessen i romanen tar ikke bare mye plass på historienivå: Den gjennomsyrer romanen. Nært forbundet med denne tematikken er et fenomen jeg ville kalle for „dobbeltperspektivet i romanen“, og det er dette jeg vil se litt nærmere på her. Selv om romanen Naustet – i god postmoderne tradisjon – i siste – og kanskje allerede i første – instans unndrar seg en fast og entydig tilskrivning av betydning – og slik bevarer sin magi – skal jeg prøve å nærme meg skriveren og dobbeltperspektivet „eit stykke på veg“. Men først et par ord om begrepet skriver.

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.

Highlights: • The framework-structured of cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2) has a 2 × 2 square tunnel. • Preparation route has an important impact on physicochemical property of the product. • Pd/OMS-2-DP via the deposition-precipitation route shows excellent catalytic activity. • Pd surface loading, surface atomic ratio of Mn ions, lattice oxygen mobility, oxygen vacancy, reducibility and acidity govern activity. - Abstract: 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 (Mn{sup 2+} + Mn{sup 3+})/Mn{sup 4+} 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 (T{sub 50%} and T{sub 90%} 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 (Mn{sup 2+} + Mn{sup 3+})/Mn{sup 4+}, 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.

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.)

Summary of LO2/Ethanol OMS/RCS Technology and Advanced Development 99-2744

Science.gov (United States)

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

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

Full Text Available A doença pulmonar obstrutiva crônica é progressiva e está relacionada a uma resposta inflamatória anormal dos pulmões à inalação de partículas e/ou gases tóxicos, sobretudo a fumaça de cigarro. Embora acometa primariamente os pulmões, diversas manifestações extrapulmonares relacionadas a esta enfermidade têm sido descritas. O aumento do número de células inflamatórias, que resulta em produção anormal de citocinas pró-inflamatórias, e o desequilíbrio entre a formação de radicais livres e a capacidade antioxidante, resultando em sobrecarga oxidativa, provavelmente são mecanismos envolvidos na inflamação local e sistêmica. Além disso, a diminuição do condicionamento físico secundária às limitações ventilatórias pode estar envolvida no desenvolvimento de alterações musculares. A doença pulmonar obstrutiva crônica apresenta diversas manifestações sistêmicas que incluem a depleção nutricional, a disfunção dos músculos esqueléticos, que contribui para a intolerância ao exercício, e as manifestações relacionadas a co-morbidades comumente observadas nestes pacientes. Essas manifestações têm sido relacionadas à sobrevida e ao estado geral de saúde dos pacientes. Nesse sentido, esta revisão tem como objetivo discutir os achados da literatura relacionados às manifestações sistêmicas da doença pulmonar obstrutiva crônica, ressaltando o papel da inflação sistêmica, e algumas perspectivas de tratamento.Chronic obstructive pulmonary disease is progressive and is characterized by abnormal inflammation of the lungs in response to inhalation of noxious particles or toxic gases, especially cigarette smoke.

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.

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.

Actualmente existen estrategias de control con el uso de fungicidas protectantes y sistémicos que contribuyen a disminuir los daños ocasionados por este hongo. Este trabajo plantea analizar la eficiencia de los fungicidas más usados comúnmente por los productores en cuatro fincas bananeras para estimar su eficiencia mediante el preaviso biológico en plantas prontas a la floración, utilizando un diseño experimental de bloques al azar con pruebas de Tukey al 0.05 de confiabilidad. Los resultados indicaron que las fincas San Andrés 1-2 y San Andrés 3 ubicadas en la zona Balao, y que usaron en sus programas de control de Sigatoka negra fungicidas protectantes y sistémicos en rotación y mezcla, además de aplicaciones de abonos foliares, presentaron valores estadísticamente diferentes a las otras fincas que aplicaron una mayor cantidad de ciclos con fungicidas sistémicos. Las fincas Elizabeth 2 y La Italia presentaron estados evolutivos más altos en las hojas más jóvenes y una emisión foliar más lenta. Se puede concluir que las fincas San Andrés 1-2 y San Andrés 3 mostraron diferencias significativas en el número de hojas sanas a la cosecha, estados evolutivos y emisión foliar, con un mejor estado fitosanitario.

Full Text Available El pensamiento sistémico contribuyó al origen de l pensamiento agroecológico con aportaciones desde la teoría general de sistemas y la cibernética como su base teórica primigenia. Así, la agroecología en los años 70 del siglo pasado pudo erigirse como una nueva forma de pensar y hacer ciencia en relación con el quehacer agrícola al intentar ir más allá del enfoque reduccionista predominante. El estudio de la realidad agrícola contemporánea exige planteamientos nuevos que permitan comprender sus dimensiones, para lo cual los principios basados en el modelo input - output que funciona bajo un controlador cibernético resultan insuficientes. En consecuencia, el propósito de este manuscrito fue analizar la evolución del pensamiento sistémico y su trascendencia en el pensamiento agroecológico, al brindar a éste úl timo herramientas teórico - conceptuales para estudiar fenómenos agrícolas actuales a través de los sistemas complejos, y con ello, involucrar aspectos poco explorados en su abordaje tradicional como la historia, la política y la cultura.

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

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.

Full Text Available RESUMO A Esclerose Sistêmica é uma doença reumática autoimune do tecido conjuntivo, progressiva, pouco frequente, de etiologia desconhecida e com evolução variável. Atinge órgãos nobres e tecidos periorais, causando limitação na abertura da boca, hipertonia dos órgãos fonoarticulatórios, face com "aparência de máscara", dificuldades na mastigação e deglutição. Com o objetivo de comparar os resultados pré e pós-intervenção fonoaudiológica miofuncional orofacial em sujeitos com esclerose sistêmica, realizou-se estudo clínico exploratório qualiquantitativo no setor de Reumatologia do Hospital Universitário e na Clínica escola de Fonoaudiologia da Universidade Federal de Sergipe, no período de julho/2012 a dezembro/2013. A amostra foi composta por cinco indivíduos, de ambos os gêneros, com faixa etária entre 24 e 60 anos e diagnóstico médico confirmado da referida afecção. Os indivíduos passaram por avaliação por meio do protocolo MBGR e 36 sessões de terapia fonoaudiológica (miofuncional e mioterápica. Ao término, os resultados iniciais e finais foram comparados a partir dos indicadores clínicos trabalhados. Diante da análise dos resultados obtidos, foram observadas melhoras em todos os aspectos trabalhados. A avaliação anterior à fonoterapia revelou restrição na abertura da boca em todos os indivíduos e os resultados finais apresentaram ganhos entre 5.3 e 14.2 mm de abertura (média: 9,26 mm. Com relação à tonicidade, mobilidade dos órgãos fonoarticulatórios e dormência orofacial, observaram-se melhoras e evidências de adequação das funções orais. Pode-se concluir que, apesar de alguns pacientes ainda apresentarem alterações, a reabilitação fonoaudiológica promoveu melhoras significativas no quadro clínico e qualidade de vida dos indivíduos do grupo de estudo.

2018-03-05

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.

Full Text Available Os autores revisaram a influência dos fatores nutricionais sobre o lúpus eritematoso sistêmico (LES e abordaram uma alternativa complementar em seu tratamento. A autoimunidade e o processo inflamatório do LES estão relacionados à presença de dislipidemias, obesidade, hipertensão arterial sistêmica e síndrome metabólica, que devem ser adequadamente consideradas para diminuir o risco cardiovascular. Uma alimentação com moderado teor energético e proteico, mas rica em vitaminas, minerais (principalmente os antioxidantes e ácidos graxos mono/poli-insaturados, pode promover ação benéfica protetora contra danos tissulares e supressão da atividade inflamatória, além de auxiliar no tratamento dessas comorbidades. A dietoterapia é uma abordagem promissora, e algumas recomendações podem oferecer melhor qualidade de vida aos pacientes com LES.The authors reviewed the influence of nutritional factors on systemic lupus erythematosus (SLE and discussed an alternative treatment option. The autoimmunity and inflammatory process of SLE are related to the presence of dyslipidemia, obesity, systemic arterial hypertension, and metabolic syndrome, which should be properly considered to decrease cardiovascular risk. A diet with moderate protein and energy content, but rich in vitamins, minerals (especially antioxidants, and mono/polyunsaturated fatty acids can promote a beneficial protective effect against tissue damage and suppression of inflammatory activity, in addition to helping the treatment of those comorbidities. Diet therapy is a promising approach and some recommendations may offer a better quality of life to patients with SLE.

Full Text Available Es mundialmente evidente el incremento de la preocupación por alcanzar un desarrollo sostenible, vinculando aspectos sociales, económicos y ambientales. En relación con este último aspecto, se ha venido manejando el concepto de gestión medioambiental desde diferentes perspectivas durante los últimos 50 años, por lo que en este trabajo se planteó como objetivo analizar la gestión medioambiental en Venezuela desde una perspectiva sistémica. La investigación es analítica con diseño de fuente mixta, documental y de campo; tomando como referencia datos documentales del conjunto de leyes ambientales existentes en Venezuela y datos empíricos mediante una encuesta a cinco empresas del sector petroquímico. Se evidenció que en Venezuela el Estado se apoya en una completa legislación pero no aplica instrumentos económicos que incentiven a las empresas a la protección del medioambiente, de igual modo sólo algunas organizaciones y especialmente aquellas cuyas actividades productivas pueden tener impacto ambiental significativo, como el caso de las empresas del sector petroquímico, integran el componente ecológico en sus prácticas gerenciales, presentando deficiencias en cuanto al cumplimiento de sus políticas ambientales y a la certificación de sus sistemas de gestión; por lo que aún se presenta como un reto el articular esfuerzos desde la perspectiva sistémica entre el Estado y el sector empresarial.

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.

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

2014-01-01

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

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

International Nuclear Information System (INIS)

Sawatzky, A.

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.

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.

Understanding the fouling of UF/MF hollow fibres of biologically treated wastewaters using advanced EfOM characterization and statistical tools

KAUST Repository

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.

Les oméga 3 : de l’alimentation animale à la nutrition humaine

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

Biodiversity Data Interoperability Issues: on the Opportunity of Exploiting O&M for Biotic Data Management

Science.gov (United States)

Oggioni, A.; Tagliolato, P.; Schleidt, K.; Carrara, P.; Grellet, S.; Sarretta, A.

2016-02-01

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.

Coating magnetic CuFe2O4 nanoparticles with OMS-2 for enhanced degradation of organic pollutants via peroxymonosulfate activation

Ye, Peng; Wu, Deming; Wang, Manye; Wei, Yi; Xu, Aihua; Li, Xiaoxia

2018-01-01

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.

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.

Den rummer videnskabsteoretiske argumenter af stor relevans...... ikke mindst forholdet mellem normative og kognitive udsagn. Efter mødet med Niels Bohrs filosofi står Rasmussens værdirelativisme både skarpere og stærkere end før, og Kasper Lippert-Rasmussens karakteristik af denne position som et ubegrundet dogme i dansk politologi er ikke overbevisende....

Phase I study of OM-174, a lipid A analogue, with assessment of immunological response, in patients with refractory solid tumors

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.

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.

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.

Full Text Available This study draws attention to what extent directors of private and municipal Early Childhood Centers (ECCs experience disagreement with school concerning questions about children’s learning in ECCs and the content of this disagreement. Furthermore, it focuses to what extent the directors of these two center categories try to influence school in such questions, and how they possibly may do this. The material derives from a nationwide survey (1310 directors and an interview study (16 directors. The directors experience disagreements to a small extent and least in private centers. However, some disagree about to which extent the adults should lead children’s learning. This study reveals a great variety in how much the directors try to influence school. The municipal directors are most active. Artikkelen retter søkelys på i hvilken grad styrere i kommunale og private barnehager opplever uenighet med skolen i spørsmål om barns læring i barnehagen og eventuelt hva slik uenighet kan handle om. Videre ser den på i hvilken grad styrere i de to barnehagetypene forsøker å påvirke skolen i spørsmål om barns læring og eventuelt på hvilke måter. Datamaterialet kommer fra en landsdekkende survey (1310 styrere og intervjuundersøkelse (16 styrere. Styrerne opplever liten grad av uenighet med skolen og minst i private barnehager.

El autor, tras una discusión somera del concepto de n.m.s. en clave sistémica, sigue la estrategia de establecer tentativamente los prerrequisitos metodológicos de la investigación constructivista de los n.m.s. conjugando el hiperempirismo institucionalista francés con el hiperteoreticismo de los sistemas sociales autopoiéticos en la propuesta de un "situacionismo" sistémico.

Fjernsynet som shaman: Om store mediebegivenheders transformative virkninger

Daniel Dayan

1988-08-01

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. I artiklens første halvdel foretages der en afgrænsning af transformative over for andre ceremonielle begivenheder. I anden halvdel gennemgås de fem faser, som udgør transformative begivenheders typiske struktur. Artiklen er bearbejdet af Jørgen Bang og Kim Schrøder. Den er oversat af Kim Schrøder.

1975-01-01

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)

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.

Estimation of atmospheric columnar organic matter (OM) mass concentration from remote sensing measurements of aerosol spectral refractive indices

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.

Full Text Available JUSTIFICATIVA E OBJETIVOS: A estimativa acurada do volume intravascular efetivo é de grande importância em pacientes submetidos a procedimentos cirúrgicos de grande porte. A avaliação da volemia, baseada na variação da pressão sistólica (VPS, (diferença entre os valores sistólicos máximos e mínimos durante um ciclo respiratório controlado mecanicamente e sua variável delta down (dDown tem se mostrado um indicador sensível da pré-carga, quando cotejados com parâmetros hemodinâmicos convencionais. Como a VPS não é um parâmetro utilizado rotineiramente para avaliação da volemia, este trabalho teve como objetivo introduzir a técnica da medida da VPS e verificar sua validade em pacientes submetidos à anestesia para cirurgia cardíaca. MÉTODO: A partir de programa de computador especialmente desenvolvido, transmitiu-se em tempo real a variação da pressão arterial a partir do monitor da sala cirúrgica para microcomputador conectado em rede. Após a adaptação deste sistema, foram estudadas as variações da pressão sistólica em nove pacientes submetidos à revascularização do miocárdio. As variáveis foram registradas em dois momentos, utilizando-se a expansão volêmica como indicador: M0 (antes da expansão volêmica e M1 (após a expansão volêmica. Também foram estudados alguns parâmetros hemodinâmicos convencionais, confrontados com a variação da pressão sistólica. RESULTADOS: Os principais resultados deste estudo mostram que a VPS, em seu componente dDown, é a que apresenta maior consistência de variação após a expansão volêmica com amido.Os demais parâmetros hemodinâmicos estudados, embora apontem para nítida melhora cardiovascular após a expansão, possuem alta variabilidade entre os pacientes e mesmo quanto à resposta ao expansor. CONCLUSÕES: Os resultados obtidos mostram que a VPS se comporta como um sensível indicador da volemia, em pacientes sob ventilação mecânica, quando

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.

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.

Betydningen av drektige reinsimlers ernæring for kalvers vekst, klimatiske toleranse og overlevelse

Full Text Available Forsøkene (viste at tilleggsforing av underernærte simler i siste del av drektighetsperioden kun synes å ha effekt på fødselsvekten for kalvene forutsatt at simlene får høyverdig ernæring etter kalving. Den forskjellige ernæringsbakgrunn før kalving synes således ikke å innvirke på melkeproduksjon/kvalitet, da vektutviklingen for alle grupper av kalver i dette forsøket gikk parallelt i de tre første ukene etter kalving. Det ble heller ikke på noe punkt funnet signifikante forskjeller gruppene imellom når det gjelder kalvenes klimatiske toleranse. Det er dog bemerkelsesverdig at det var stor dødelighet blant de små kalvene etter unge små simler i GRUPPE L. Dette funn er interessant sett i sammenheng med resultatene fra Røros (se bidrag fra Dag Lenvik, side som viser at avkastningen fra en flokk kan økes markant om man konsentrerte slakteuttaket på små kalver og forhindrer bedekning av små, unge simler gjennom fjerning av eldre, store bukker. Med det forbehold at våre forsøk er utført på dyr i innhegning med et lavt aktivitetsnivå, kan man fra våreforsøk foreløpig konkludere med at tillegsfor ing av simler i siste halvdel av drektighetsperioden har effekt på kalvenes fødselsvekt, men at vektutviklingen for kalven er uavhengig av simlenes ernæringshistorie, om sistnevnte tilbys høyverdig ernæring etter kalving. Da små kalver etter underernærte simler viste høy dødelighet like etter fødselen, vil imidlertid tilleggsforing kunne øke avkastningen om det er mange unge simler i flokken. Resultatene fra Røros tyder imidlertid på at dette resultat normalt kan oppnås uten ekstra omkostninger gjennom et selektivt slakteuttak.

Metakognisjon om språk og språklæring i et flerspråklighetsperspektiv

Full Text Available I denne artikkelen drøfter jeg betydningen av elevers refleksjon om språk og språklæring. Artikkelens første del gir en kort introduksjon til forskningsfeltet metakognisjon. Deretter presenterer jeg to underkategorier av metakognisjon som er særlig relevante i språkundervisningen, metalingvistisk bevissthet og bevissthet om språklæringsstrategier. I artikkelens andre del introduserer jeg hovedprinsippene i flerspråklighetsdidaktikken, gir eksempler på hvordan elevene kan reflektere over språk og språklæring i språkfagene og argumenterer for at økt vekt på metakognisjon i og på tvers av språkfagene er en nøkkel til bedre språkkompetanse hos fremtidige elever. Dette krever imidlertid et sterkere samarbeid mellom språkfagene i skole, lærerutdanning og forskning.

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.
