    Neuroendocrine tumors (neuroendokrine Tumoren) are rare entities. They can be found in all organs and show substantial biologic heterogeneity depending on involved organ, clinical symptoms and histopathologic morphology. Involvement of organs like larynx, cervix uteri, ovary, gallbladder, liver or kidney is extensively rare. The majority of neuroendokrine Tumoren are found in gastrointestinal tract and lung and are classified as neuroendokrine Tumoren of foregut (stomach, duodenum, pancreas, lung), midgut (jejunum, ileum, appendix, right side of the colon) and hindgut (left side of the colon, rectum). The role of imaging is to localize and delineate the primary tumor and to detect metastases. In the diagnosis of neuroendokrine Tumoren radiologic techniques like computed tomography (CT) and magnetic resonance imaging (MRI) are applied. In certain cases nuclear medicine techniques like somatostatin receptor scintigraphy (SRS) and positron emission tomography (PET) using radioactively labelled somatostatin analogues are used. The present article reviews characteristic imaging findings of neuroendokrine Tumoren of the gastrointestinal tract. (orig.)

    Tumors of the disseminated/diffuse neuroendocrine system (NET) are characterized by a common phenotype. However, the biology varies according to histomorphology, endocrine symptoms and organ of origin. The WHO classification takes these differences into account and uses a common framework, where the parameters size and extent of invasion vary according to the organ of origin. In order to achieve a further standardization of reporting the European Neuroendocrine Tumor Society (ENETS) recently proposed a tumor-node-metastasis (TNM) staging and grading system for gastro-entero-pancreatic NET. (orig.) [German] Tumoren des disseminierten/diffusen neuroendokrinen Systems sind durch einen gemeinsamen Phaenotyp gekennzeichnet. In ihrer Biologie unterscheiden sich neuroendokrine Tumoren (NET) jedoch bzgl. Morphologie, endokrinologischer Symptomatik und Ursprungsorgan. Die WHO-Klassifikation traegt diesen Unterschieden Rechnung und klassifiziert NET nach einem einheitlichen Vorgehen, wobei die Parameter Groesse und Invasionstiefe je nach Ursprungsorgan variieren. Um die Nomenklatur weiter zu vereinheitlichen, wurde vor kurzem von der ''European Neuroendocrine Tumor Society'' (ENETS) der Vorschlag einer TNM-Stadien-Einteilung und Graduierung gastroenteropankreatischer NET vorgelegt.

    Pancreatic neuroendocrine neoplasms (NEN) account for 1-2 % of all pancreatic neoplasms and represent a rare differential diagnosis. While some pancreatic NEN are hormonally active and exhibit endocrine activity associated with characteristic symptoms, the majority are hormonally inactive. Imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) or as combined PET/CT play a crucial role in the initial diagnosis, therapy planning and control. Endoscopic ultrasound (EUS) and multiphase CT represent the reference methods for localization of the primary pancreatic tumor. Particularly in the evaluation of small liver lesions MRI is the method of choice. Somatostatin receptor scintigraphy and somatostatin receptor PET/CT are of particular value for whole body staging and special aspects of further therapy planning. (orig.) [German] Neuroendokrine Neoplasien (NEN) des Pankreas stellen mit einem Anteil von 1-2 % aller pankreatischen Tumoren eine seltene Differenzialdiagnose dar. Ein Teil der Tumoren ist hormonell aktiv und faellt klinisch durch charakteristische Symptome auf, wohingegen der ueberwiegende Anteil hormonell inaktiv ist. Bildgebende Verfahren wie Sonographie, Computertomographie (CT), Magnetresonanztomographie (MRT) und nicht zuletzt Positronenemissionstomographie (PET oder kombiniert als PET/CT) spielen eine zentrale Rolle fuer Erstdiagnose, Therapieplanung und -kontrolle. Die Endosonographie und die multiphasische CT stellen die Referenzmethoden zur Lokalisation des Primaertumors dar. Fuer die Differenzierung insbesondere kleiner Leberlaesionen bietet die MRT die hoechste Aussagekraft. Fuer das Ganzkoerperstaging und bestimmte Aspekte der Therapieplanung lassen sich die Somatostatinrezeptorszintigraphie und v. a. die Somatostatinrezeptor-PET/CT heranziehen. (orig.)

    Diseases of the parathyroids, the adrenals and of neuroendocrine tumors of the pancreas are primarily diagnosed by clinical and endocrinological evaluation.The requirements concerning various imaging techniques and their relative importance in localization strategies of the different tumors are complex. Current literature search, using PubMed. Evaluation of primary hyperparathyroidism requires bone densitometry by DXA and search for nephrolithiasis by ultrasound or native CT examination.While ultrasound of the thyroid and parathyroids seems useful before any parathyroid surgery,more extensive preoperative localization strategies (sestamibi scintigraphy, MRI) should be restricted to minimal invasive parathyroid surgery or reoperations.For adrenal tumors CT and MRI are of similar diagnostic value. Imaging of pheochromocytomas should be completed by MIBG scintigraphy. Each adrenal incidentaloma requires an endocrinological work-up.A fine-needle aspiration or core needle biopsy of an adrenal tumor is rarely indicated.Before adrenal biopsy a pheochromocytoma has to be excluded.Successful localization strategies for neuroendocrine tumors of the pancreas include somatostatin receptor scintigraphy, endoscopic ultrasound and MRI.Discussion Specific localization strategies have been established for the aforementioned tumors.The continuous progress of different imaging techniques requires a regular reevaluation of these localization strategies.

    Receptor PET/CT using {sup 68}Ga-labeled somatostatin analogues (DOTA-NOC, DOTA-TOC or DOTA-TATE) enables the highly sensitive molecular imaging of neuroendocrine tumors (NETs) based on the expression of somatostatin receptors and even the detection of receptor subtypes. Our experience after more than 3000 studies shows that receptor PET/CT has a significantly higher tumor detection rate than conventional scintigraphy (even in SPECT/CT technique), and that tumor lesions can be very accurately localized. By calculating standardized uptake values (SUV) - which are reproducible and investigator-independent - patients can be selected for peptide receptor radiotherapy and also the course after therapy can be controlled. Receptor-PET/CT is the most sensitive imaging modality for the detection of unknown primary tumors (CUP syndrome), which is especially true for the detection of neuroendocrine tumors of the pancreas and small bowel; whole-body staging (''one stop shop'') as well as restaging and selection of patients for peptide receptor radiotherapy can be performed using a patient-friendly procedure (examination finished within one hour) exposing the patient to less radiation than whole-body CT scanning. The {sup 68}Ge/{sup 68}Ga generator has proved very reliable over the years - even in a hospital environment. The effective costs for {sup 68}Ga labeled somatostatin analogues might be less than for scintigraphic agents, provided a certain number of studies per year are performed. The development of new tumor-specific peptides as well as of other DOTA- or NOTA-coupled radiopharmaceuticals opens a new avenue into the future: finally, the {sup 68}Ga generator could play a similar important role for PET/CT as did the {sup 99m}Tc-Generator for conventional gamma camera imaging over the last decades.

    Therapy of neuroendocrine tumors (NET) using radiolabelled somatostatin receptors such as {sup 177}-Lu-DOTATATE or {sup 90}Y-DOTATOC is gaining more and more importance. Due to the over expression of somatostatin receptors in NET the tumor-to-background ratio is very favourable. A significant therapy response is achievable between 20% and up to 46% of treated patients with a median time to progression of up to 40 months. Furthermore, this kind of therapy is very beneficial in the case of hormonal active, functional NET in terms of symptom control. Also quality of life is significantly improved after therapy, even in non-responding patients. The most common side effects of this therapy are nausea, vomiting and transient hematologic toxicity. However, late serious side effects such as renal impairment or myelodysplastic syndrome are rare if renal protection is used during the course of therapy. (orig.)

  10. M, Membranes, and OM

    CERN Document Server

    García, J A; Vergara, J D; Guijosa, Alberto

    2003-01-01

    We examine the extent to which the action for the membrane of M-theory (the eleven-dimensional construct which underlies and unifies all of the known string theories) simplifies in the so-called Open Membrane (OM) limit, a limit which lies at the root of the various manifestations of noncommutativity in the string context. In order for the discussion to be relatively self-contained, we start out by reviewing why the strings of ten-dimensional string theory are in fact membranes (M2-branes) living in eleven dimensions. After that, we recall the definition of OM theory, as well as the arguments showing that it is part of a larger, eleven-dimensional structure known as Galilean or Wrapped M2-brane (WM2) theory. WM2 theory is a rich theoretical construct which is interesting for several reasons, in particular because it is essentially a toy model of M-theory. We then proceed to deduce a membrane action for OM/WM2 theory, and spell out its implications for the four different types of M2-branes one can consider in ...

    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.

    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.

  20. Kampen om matfatet og matproduksjonen

    2013-05-01

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

    % aller gastrointestinalen Tumoren ausmacht. Fuer die Lokalisation des Primaertumors als auch fuer das Staging endokriner Tumoren spielen neben der Ultraschalldiagnostik die Computertomographie (CT), die Magnetresonanztomographie (MRT) und die Positronenemissionstomographie-Computertomographie (PET-CT) eine entscheidende Rolle. Neben dem Primaerstaging lassen sich mithilfe der PET-CT mit Somatostatinanaloga auch die Indikation fuer eine Radionuklidtherapie stellen und der Therapieverlauf dokumentieren. Das CT-Enteroklysma erreicht nach der Literatur bei Duenndarmtumoren bis 3 cm eine Sensitivitaet von 84,7 %, eine Spezifitaet von 96,9 %; mit der Magnetresonanzenterographie (MRE) kann ein neuroendokriner Tumor (NET) des Duenndarms in 93,3 % der Faelle lokalisiert werden. Laut Literatur ist die MRT bei der Detektion pankreatischer NET mit einer Sensitivitaet zwischen 74 und 100 % der CT ueberlegen. Die PET-CT ermoeglicht die Detektion sehr kleiner Primaertumoren und gilt als sensitivste Methode zur Lokalisationsdiagnostik. Bei der Detektion von Lebermetastasen ist die MRT der CT und der PET-CT ueberlegen. Aufgabe der bildgebenden Diagnostik ist es, neben der Lokalisation des Primaertumors und dem Staging, Therapien zu planen und ein Therapieansprechen zu dokumentieren. Die Wahl der verschiedenen bildgebenden Verfahren hierfuer ist abhaengig von der Lokalisation des Primaertumors. Da gastroenteropankreatische neuroendokrine Tumoren (GEP-NET) ueberwiegend hypervaskularisiert sind, ist eine biphasische Untersuchungstechnik nach Kontrastmittelgabe in arterieller und venoeser Phase fuer die Abklaerung von Primaertumoren und Metastasen sowohl in der CT wie in der MRT obligat. Fuer das Ganzkoerperstaging kommen vorrangig CT und PET-CT zum Einsatz. (orig.)

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

    Science.gov (United States)

    Kurulugama, Ruwan T.; Nachtigall, Fabiane M.; Valentine, Stephen J.; Clemmer, David E.

    2011-11-01

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

    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.

    2017-09-01

    The stability and persistence of organic matter (OM) in source rocks are of great significance for hydrocarbon generation and the global carbon cycle. Clay-OM associations commonly occur in sedimentation and diagenesis processes and can influence the pyrolytic behaviors of OM. In this study, clay-OM complexes, i.e., interlayer clay-OM complexes and clay-OM mixture, were prepared and exposed to high-pressure pyrolysis conditions in confined gold capsule reactors to assess variations in OM pyrolysis products in the presence of clay minerals. Three model organic compounds, octadecanoic acid (OA), octadecy trimethyl ammonium bromide (OTAB), and octadecylamine (ODA), were employed and montmorillonite (Mt) was selected as the representative clay mineral. The solid acidity of Mt plays a key role in affecting the amount and composition of the pyrolysis gases generated by the clay-OM complexes. The Brønsted acid sites significantly promote the cracking of hydrocarbons through a carbocation mechanism and the isomerization of normal hydrocarbons. The Lewis acid sites are primarily involved in the decarboxylation reaction during pyrolysis and are responsible for CO2 generation. Mt exhibits either a catalysis effect or pyrolysis-inhibiting during pyrolysis of a given OM depending on the nature of the model organic compound and the nature of the clay-OM complexation. The amounts of C1-5 hydrocarbons and CO2 that are released from the Mt-OA and Mt-ODA complexes were higher than those of the parent OA and ODA, respectively, indicating a catalysis effect of Mt. In contrast, the amount of C1-5 hydrocarbons produced from the pyrolysis of Mt-OTAB complexes was lower than that of OTAB, which we attribute to an inhibiting effect of Mt. This pyrolysis-inhibiting effect works through the Hoffmann elimination that is promoted by the catalysis of the Brønsted acid sites of Mt, therefore releasing smaller amounts of gas hydrocarbons than the nucleophilic reaction that is induced by the

  15. Om: One tool for many (Indian) languages

    Institute of Scientific and Technical Information of China (English)

    GANAPATHIRAJU Madhavi; BALAKRISHNAN Mini; BALAKRISHNAN N.; REDDY Raj

    2005-01-01

    Many different languages are spoken in India, each language being the mother tongue of tens of millions of people.While the languages and scripts are distinct from each other, the grammar and the alphabet are similar to a large extent. One common feature is that all the Indian languages are phonetic in nature. In this paper we describe the development of a translit eration scheme Om which exploits this phonetic nature of the alphabet. Om uses ASCⅡ characters to represent Indian language alphabets, and thus can be read directly in English, by a large number of users who cannot read script in other Indian languages than their mother tongue. It is also useful in computer applications where local language tools such as email and chat are not yet available. Another significant contribution presented in this paper is the development of a text editor for Indian languages that integrates the Om input for many Indian languages into a word processor such as Microsoft WinWord(R). The text editor is also developed on Java(R) platform that can run on Unix machines as well. We propose this transliteration scheme as a possible standard for Indian language transliteration and keyboard entry.

    Full Text Available I lys av utviklingen av barnehagens posisjon i det norske samfunnet og debatten om effekter av barnehagens fysiske miljø og organisering, dannet en gruppe tverrfaglige og tverrinstitusjonelle barnehageforskere i 2004 forskningsnettverket Barn og Rom. Nettverkets mål har vært å "skape ny og forskningsbasert kunnskap om det fysiske miljøets betydning for barn, og samtidig være et forum for kunnskapsdeling, utvikling av felles forskningsprosjekter, formidling og publisering, samt internasjonalt samarbeid med andre aktører og forskningsgrupper". Forskningsnettverket opererer med en definisjon av "Barn og Rom" som i vid forstand omfatter hele det fysiske miljøet barn vokser opp i. Dette inkluderer ulike landskap, for eksempel byen og naturen, steder, bygninger, ute- og innerom, innredning, møbler, utstyr, installasjoner og lekeapparater. Likevel har nettverket hatt et særlig fokus på barnehagens fysiske miljø og dets betydning for barn, personalet og den pedagogiske virksomheten og hvordan miljøet forstås, organiseres, skapes og endres av personalet og barn i barnehagen. Dette temanummeret er et resultat av noen av nettverksmedlemmenes arbeid de siste årene og presenterer en stor bredde både i metodisk tilnærming så vel som tematisk tilnærming til temaet "Barn og rom".

    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.

  5. Kan Batman dateres? Om massekommunikasjonen som kulturhistorie

    Directory of Open Access Journals (Sweden)

    Hans Frederik Dahl

    1990-08-01

    Full Text Available Hans Frederik Dahls artikel er et bud på om massekommunikationen kan tænkes ind i kulturhistorien.Første halvdel af artiklen fremhæver de prob- lemer, det rejser, når massekommunikation med dens karakteristika i form af serialitet, triviatitet og internationalitet skal reflekteres i forhold til en kulturhistorisk tradition, som normalt tænker i begreber som tidsånd, kunstnerisk originalitet og nationalt særpræg. Sidste halvdel focuserer på tre centrale aspekter ved massekommunikationen, som også er af- gørende for dens kulturhistorie: dens nære forbindelse til musikken, dens internationale karakter og dens konstante tilbagevenden til tidligere pro- dukter.

  16. 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.

  18. 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.

    Yong-Wu Li; Lin Bai; Lyu-Xia Dai; Xu He; Xian-Ping Zhou

    2016-01-01

    Background: Lung cancer has become the leading cause of death in many regions.Carcinogenesis is caused by the stepwise accumulation of genetic and chromosomal changes.The aim of this study was to investigate the chromosome and gene alterations in the human lung adenocarcinoma cell line OM.Methods: We used Giemsa banding and multiplex fluorescence in situ hybridization focusing on the human lung adenocarcinoma cell line OM to analyze its chromosome alterations.In addition, the gains and losses in the specific chromosome regions were identified by comparative genomic hybridization (CGH) and the amplifications of cancer-related genes were also detected by polymerase chain reaction (PCR).Results: We identified a large number of chromosomal numerical alterations on all chromosomes except chromosome X and 19.Chromosome 10 is the most frequently involved in translocations with six different interchromosomal translocations.CGH revealed the gains on chromosome regions of 3q25.3-28, 5p13, 12q22-23.24, and the losses on 3p25-26, 6p25, 6q26-27, 7q34-36, 8p22-23, 9p21-24, 10q25-26.3, 12p 13.31-13.33 and 17p 13.1-13.3.And PCR showed the amplification of genes: Membrane metalloendopeptidase (MME), sucrase-isomaltase (SI), butyrylcholinesterase (BCHE), and kininogen (KNG).Conclusions: The lung adenocarcinoma cell line OM exhibited multiple complex karyotypes, and chromosome 10 was frequently involved in chromosomal translocation, which may play key roles in tumorigenesis.We speculated that the oncogenes may be located at 3q25.3-28, 5p13, 12q22-23.24, while tumor suppressor genes may exist in 3p25-26, 6p25, 6q26-27, 7q34-36, 8p22-23, 9p21-24, 10q25-26.3, 12p 13.31-13.33, and 17p 13.1-13.3.Moreover, at least four genes (MME, SI, BCHE, and KNG) may be involved in the human lung adenocarcinoma cell line OM.

  4. 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.

    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.

  7. Nonparametric reconstruction of the Om diagnostic to test LCDM

    CERN Document Server

    Escamilla-Rivera, Celia

    2015-01-01

    Cosmic acceleration is usually related with the unknown dark energy, which equation of state, w(z), is constrained and numerically confronted with independent astrophysical data. In order to make a diagnostic of w(z), the introduction of a null test of dark energy can be done using a diagnostic function of redshift, Om. In this work we present a nonparametric reconstruction of this diagnostic using the so-called Loess-Simex factory to test the concordance model with the advantage that this approach offers an alternative way to relax the use of priors and find a possible 'w' that reliably describe the data with no previous knowledge of a cosmological model. Our results demonstrate that the method applied to the dynamical Om diagnostic finds a preference for a dark energy model with equation of state w =-2/3, which correspond to a static domain wall network.

    We study the motion of neutral test particles along circular orbits in the Reissner-Nordstr\\"om spacetime. We use the method of the effective potential with the constants of motion associated to the underlying Killing symmetries. A comparison between the black hole and naked singularity cases is performed. In particular we find that in the naked singularity case for $rQ^2/M$ and $1\\sqrt{5}/2$ there are all stable circular orbits for $r>Q^2/M$.

    Full Text Available De fleste af os har en helt klar fornemmelse for, hvad der er skidt og kanel på kulturmarkedet, hvadenten det drejer sig om maleri, musik, litteratur eller TV-fiktion. Kim Schrøder plæderer i denne artikel for, at den øgede indsigt i tekstoplevelser, som receptionsforskningen har skabt i de senere år, må føre frem til en rehabilitering af "den folkelige smag" og til et opgør med "den gode smags tyranni": med den herskende opfat- telse af kulturel kvalitet, der ser bort fra oplevelseskvaliteten og udelukkende baserer sin kvalitetsvurdering på værkets formelle æstetiske træk. Han rejser bl.a. det spørgsmål, om man ikke bliver nødt til at opgive en almengyldig forestilling om, hvad kvalitet er, så både "godt" og "dårligt" altid er godt og dårligt for nogen? - Men hvis man virkelig accepterer, at "smag og behag er forskellig", må det få kulturpoliti- ske konsekvenser, som artiklen til slut kommer ind på.

  19. 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.

  20. 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

    We analyze the tidal forces produced in the spacetime of Reissner-Nordstr\\"om black holes. We point out that the radial component of the tidal force changes sign just outside the event horizon if the charge-to-mass ratio is close to $1$ unlike in Schwarzschild spacetime of uncharged black holes, and that the angular component changes sign between the outer and inner horizons. We solve the geodesic deviation equations for radially falling bodies towards the charged black hole. We find, for example, that the radial component of the geodesic deviation vector starts decreasing inside the event horizon unlike in the Schwarzschild case.

    Based on the consideration that the black hole horizon and the cosmological horizon of Reissner-Nordstr\\"om black hole in de Sitter space are not independent each other, we conjecture the total entropy of the system should have an extra term contributed from the entanglement between the two horizons, except for the sum of the two horizon entropies. Making use of the globally effective first law and the effective thermodynamic quantities, we derive the total entropy and find that it will diverge as the two horizons tends to coincide.

    Résumé Question À la lumière de la hausse du nombre d’enfants d’âge scolaire ayant reçu un diagnostic de dyslexie, quel est le rôle des suppléments d’acides gras oméga-3 dans la prise en charge de cette affection? Réponse La dyslexie est le trouble d’apprentissage le plus répandu et elle est connue pour ses causes multifactorielles. De récentes données probantes pointent vers une corrélation entre le métabolisme défectueux des acides gras polyinsaturés et les troubles de neurodéveloppement, tels que la dyslexie. Bien que l’administration de suppléments d’acides gras oméga-3 aux enfants dyslexiques ait fait l’objet d’études, les données probantes sont limitées. Les critères diagnostiques homogènes de dyslexie, les mesures objectives de carence en acides gras et la surveillance étroite de l’apport alimentaire ne sont que quelques-uns des facteurs pouvant améliorer la qualité de la recherche dans ce domaine.

    Full Text Available Purpose: To determine the prevalence of Otitis media (OM and Early childhood caries (ECC and their coexistence in children with a history of faulty feeding patterns. Method: Children aged 5 years and below were recruited at random from dental and medical hospitals. Parents of these children were posed with questions about the feeding methods, feeding patterns such as duration, frequency, position, burping, specific childhood illness etc. Children (120 were examined for ECC by a Paedodontist and OM by an Otolaryngologist and were segregated into three groups i.e. Control group, ECC group and OM group respectively. The ECC group was sub grouped into ECC only and ECC&OM group. The OM group was also similarly sub grouped into OM group and OM&ECC group. Collected data were tabulated and subjected for statistical analysis using Pearson Chi – square test. Results: Prevalence of ECC, OM, and their coexistence increased with age P < 0.001, whereas gender difference was not statistically significant. Overall Prevalence of their coexistence in children was 51.25%. Significant percentages (25% of children in the OM group were fed in supine position. Children fed on demand (47.5% experienced ECC. overall 85% (p=.017 of children had coexistence of ECC&OM fed on demand and during bed time. Significant numbers of children who were burped occasionally after feeding (35% or were not burped at all (12.5% were affected with both ECC and OM. Conclusion: Prevalence of their coexistence was higher in children with OM. Significant association existed between on demand feeding and ECC; supine feeding position and OM. Risk factors in common for both the disease were combined feeding position, on demand, bed time feeding and occasionally burping.

    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.

    The need for integrated analysis, and the multiplicity of possible goals in analyses that require hydro-biophysical modelling, necessitates more than ever the capability of composing modelling solutions with parts of known quality, which are transparent to users and consist of reusable model components. Moreover, modern hydrological modelling requires interaction with GIS tools to allow visualizations and the data-processing necessary to synthesise knowledge from high volumes of inputs and outputs data. Last but not least, doing science that is reproducible has requirements that go beyond the computational issues to embrace the possibility to inspection the tools, and easy compare modelling solutions by third party groups. The JGrass-NewAge system was born in order to satisfy these requirements. It is based on the geographic information system uDig-JGrass, and is composed of two parts: (i) the system of visualization of the data and of the results based on uDig; (ii) the modelling components. The latter are implemented as OMS3 components which can be connected or excluded at runtime, according to the needs and works seamlessly inside the uDig Spatial Toolbox. The system is based on a hillslope-link geometrical partition of the landscape, thus the basic unit, where the water budget is evaluated, is the hillslope, and each one of them drains into a single associated link rather than cells or pixels. To this conceptual partition corresponds an implementation of informatics that uses vectorial features for channels, and raster data for hillslopes. The mass budget for each hillslope can be performed in two ways: according to a modification of Duffy dynamical model of hillslope runoff or according to HyMod lumped model. Differently from traditional rainfall-runoff models where the discharge is usually given at the outlet of a catchment, the discharge is evaluated in each link of the river network according to a procedure presented in Cuencas model. The system includes

    Full Text Available Den korte og følelsesladede debatten mellom den tyske typografen og designeren Jan Tschichold og den sveitsiske arkitekten og designeren Max Bill fra 1946 berører noen sentrale estetiske og funksjonelle aspekter ved typografi og grafisk design. Foranledningen for debatten var at Tschichold i løpet av krigsårene 1940–45 hadde vendt seg mot sine tidligere standpunkter og gått til angrep på funksjonalismen og «den nye typografien». Isteden tok han den tradisjonelle, symmetriske typografien i forsvar og gav den en fornyelse og en kvalitetsheving. Artikkelen tar for seg debatten og kommenterer de ulike standpunktene i lys av den senere faghistorien, og fokuserer spesielt på hvordan ideologi og tidsavhengig tanke­gods kan påvirke argumenter om funksjonalitet og estetikk.

    2016-01-01

    A model of nonlinear electrodynamics coupled with the gravitational field is studied. We obtain the asymptotic black hole solutions at $r\\rightarrow 0$ and $r\\rightarrow \\infty$. The asymptotic at $r\\rightarrow 0$ is shown, and we find corrections to the Reissner-Nordstr\\"om solution and Coulomb's law at $r\\rightarrow\\infty$. The mass of the black hole is evaluated having the electromagnetic origin. We investigate the thermodynamics of charged black holes and their thermal stability. The critical point corresponding to the second-order phase transition (where heat capacity diverges) is found. If the mass of the black hole is greater than the critical mass, the black hole becomes unstable.

    Full Text Available This article highlight the goal of 20 percent male employees in Norwegian kindergartens as a contribution to promoting gender equality. We conducted two studies showing different expectations towards men and women. Informants are positive to increasing the number of men, but in the two surveys they expressed conflicting expectations towards the role of men in kindergartens. In the survey among male preschool students they have objections to recruit men as a group because they are men (Kasin et al. 2010. In the survey among employees in kindergartens they desire men just because they are men, different from women. Their rationale is that this creates diversity (Kasin and Slåtten 2011. We discuss this seeming contradiction in the informants' views on the basis of different perceptions about gender. By using different levels of analysis we show how male employees can be understood in several ways that promotes gender equality. At the societal level, several men in kindergarten can be seen as part of a liberal policy to promote equal rights and opportunities for labor force participation. At the institutional level, gender equality depends on activities in the educational program. At the individual level equality can be understood as practices among each employee that prevent stereotyped gender understanding, and through these practices give children equal opportunities across gender divides. Our own research indicates that exclusive focuses on the representation of male employees in kindergartens are likely to conceal rather than to clarify a need to develop educational practices that promote gender equality. Artikkelen belyser målsettingen om 20 prosent menn i norske barnehager som bidrag til å fremme likestilling i barnehagen.

    Full Text Available I slöjdundervisningen i Sverige är ett av målen att eleven skall utveckla förmågan att göra och motivera personliga ställningstaganden kring estetiska värden. I en studie med elever i grundskolan (Homlong, 2006a,b visade det sig att eleverna hade klara åsikter om vad de tyckte om några olikt mönstrade tyger, men saknade formalestetiska begrepp för att förklara dessa åsikter. De begrundade i stor grad sina ställningstaganden med funktionella användningsområden eller hänvisning till personliga erfarenheter av liknande mönster, färger eller textilier.Undersökningsmetoden som användes i studien The Language of Textiles (Homlong, 2006a var en modifierad Repertory Grid där eleven i flera omgångar skulle välja mellan tre olikt mönstrade tyger och motivera valen. Metoden bygger på att den jämförande analysen lyfter fram likheter och olikheter i en process där begrepp och deras motsatsbenämningar lyfts fram. Denna artikel visar exempel på hur eleverna i studien motiverade sina ställningstagande, i vilka situationer och på vilka områden de hade problem med att förklara orsaken till sina ställnings-taganden, och föreslår hur en jämförande analysmetod kan bidra till utveckling av kommunikation kring estetiska aspekter i slöjdundervisningen.

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

    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.

    CERN Document Server

    2016-01-01

    Starting from a Geometrothermodynamics metric for the space of thermodynamic equilibrium states in the mass representation, we use numerical techniques to analyse the thermodynamic geodesics of a supermassive Reissner Nordstr\\"om black hole in isolation. Appropriate constraints are obtained by taking into account the processes of Hawking radiation and Schwinger pair-production. We model the black hole in line with the work of Hiscock and Weems. It can be deduced that the relation which the geodesics establish between the entropy $S$ and electric charge $Q$ of the black hole extremises changes in the black hole's mass. Indeed, at any given point along a geodesic, the value of $\\text{d}S/\\text{d}Q$ is of the same order of magnitude as the rate at which entropy changes with charge during a constant-mass perturbation. Our claim is further justified by the fact that the expression for the entropy of an extremal black hole is an exact solution to the geodesic equation.

    Full Text Available En stor del av språkvetenskapen vilar sedan länge på en snäv idé om sitt kunskapsobjekt. Inställningen är nomotetisk och logocentrisk. Med språk avses ett regelbundet system. Fastän denna inställning mött mycket motstånd, har den väl i praktiken aldrig skakats i grunden. Denna undersökning försöker därför ännu en gång att presentera ett alternativt språkbegrepp. Teorin är dialogisk och hermeneutisk: den språkliga betydelsens plats i världen och tolkningen som grunden för all betydelse är vägledande principer. Genom dessa principer introduceras två begreppsliga ramverk. Det första lägger grunden för en kontinuerlig språkmodell som försöker att upplösa dikotomin mellan system och bruk. Till denna modell fogas sedan en tolkningstypologi. Denna har ett dubbelt syfte. Å ena sidan möjliggör den en systematisk jämförelse av språkvetenskapens discipliner. Å andra sidan är den en beskrivning av språkets betydelsestruktur.

    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.

    The atmosphere of Titan contains nitrogen, methane, and a rich mixture of more complex hydrocarbons and nitriles produced by photochemical processing. Data from the 2005 Cassini-Huygens mission suggests that among the more complex compounds are substituted benzenes that are themselves precursors to large polymeric tholins. Nitriles are particularly prevalent in Titan's atmosphere due to the dominance of N2 in the atmosphere. The cyanostyrenes are of particular interest, in part because they have the same molecular formula (C9H7N) as quinoline, a prototypical heteroaromatic, and therefore could engage in photochemical isomerization to form this molecule of significant pre-biotic relevance. As a first step in understanding the pathways leading to heteroaromatics, we have studied the isotope-selective spectroscopy of o-,m-, and p-cyanostyrene under jet-cooled conditions relevant to Titan's atmosphere. In this talk, the excitation and emission spectra for the three isomers will be presented. Using a combination of resonant two-photon ionization, LIF excitation, and dispersed fluorescence spectroscopies, the vibronic spectroscopy of the three isomers were recorded and compared. The meta isomer has two conformational isomers, which have been distinguished and studied using hole-burning methods. The talk will compare and contrast the UV spectral signatures of the set of structural and conformational isomers of the cyanostyrenes, using the ethynylstyrene counterparts as points of comparison.

    Surprisingly little is known about how shifts in tree species composition and increased forest fire frequency and intensity will affect one of the most stable pools of soil organic matter, i.e. the pyrogenic organic matter (PyOM or char). In a previous study, we showed that wood source and pyrolysis temperature interact to control PyOM structure and potential reactivity for two tree species common in high-latitude forests, jack pine (JP) and red maple (RM). Here, we investigate whether these differences affect PyOM turnover by examining the fates of 13C/15N-enriched JP wood and PyOM pyrolyzed at 300 (JP300) and 450 °C (JP450) and RM pyrolyzed at 450 °C (RM450). The substrates were applied 1-3 cm below the O/A interface of a well-drained Spodosol in a long-term forest fire study located at the University of Michigan Biological Station (Pellston, MI, USA). 13C-CO2effluxes from the first 996 days of decay showed a significant wood source by pyrolysis temperature interaction on PyOM field mineralisation rates, with RM450 mineralising twice faster than JP450 during the first 90 days. Increasing pyrolysis temperature substantially decreased field mineralization rates during the first 996 days, with mineralisation rates 24 and 80 times slower for JP300 and JP450 compared with JP wood. After 1 year, (i) bacterial groups were large sinks for PyOM-derived C as pyrolysis temperature increased and as substrate use efficiency decreased; (ii) potential phenol oxidase and net peroxidase activities were unaffected by the PyOM addition, although net peroxidase activities measured tended to lesser for soils amended with JP450 and RM450; and (iii) Collembola detritivores appeared less likely to be found for soils amended with JP450 and RM450. PyOM-derived C and N recoveries did not differ after 1 year; we will present 3-y recovery data. Our results suggest that the composition of angiosperms (e.g. RM) and gymnosperms (e.g. JP) in high-latitude forests is an underappreciated but

    Surprisingly little is known about how pyrolysis temperature and wood source affect the stability of forest-fire derived pyrogenic organic matter (PyOM). Here, we show that wood source and temperature affect in situ mineralization rates of PyOM in soils for two co-occurring gymnosperm (jack pine; JP [Pinus banksiana]) and angiosperm (red maple; RM [Acer rubrum])¬ species from North American boreal-temperate ecotones. We assess the effect of pyrolysis temperature on PyOM fates by following the decay of 13C/15N-enriched JP wood (JPwood) and PyOM produced at 300 °C (JP300) and 450 °C (JP450); and assess the effect of PyOM wood source by comparing fates of JP450 and RM450. JPwood mineralized 18× faster than JP300 and 44× faster than JP450 after 2.8y. RM450 mineralized initially faster than JP450 during the first ~2y, but became equivalent afterwards (1.1±0.2% of CO¬2 losses after 2.8y). Modeled turnover times suggest that this can be attributed to ~1% of fast-cycling PyOM (wood source (yet); N recoveries did not differ. PLFA-(13)C data reveal that (i) treatments have similar microbial communities after 1y, (ii) JPwood is preferentially utilized by fungi, and (iii) bacteria increasingly utilize PyOM as pyrolysis temperature increases. Estimated carbon use efficiency decreased with increasing pyrolysis temperature (JPwood~JP300>JP450~RM450). Although insignificant, potential phenol oxidase and peroxidase activities decrease with increasing pyrolysis temperature. Neither PyOM nor wood additions (~11% of soil C stock 0-20 cm depth) affected pH or Ec after 1y. We provide the first, field experimental evidence that pyrolysis temperature and wood source affect the turnover of PyOM in soil. We show faster, initial decay for PyOM produced at lesser temperature and RM (angiosperm) compared with JP (gymnosperm). This study offers realistic insights on (i) the controls underlying in situ PyOM turnover, and on (ii) how ongoing/projected changes in tree species composition

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

    Energy Technology Data Exchange (ETDEWEB)

    Klise, Geoffrey Taylor [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States); Balfour, John [High Performance PV, Phoenix, AZ (United States)

    2015-11-01

    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.

  17. Argyrophilic nucleolar organizer regions (AgNORs) in odontogenic myxoma (OM) and ameloblastic fibroma (AF).

    Martins, C; Carvalho, Y R; do Carmo, M A

    2001-09-01

    Ten cases of odontogenic myxoma (OM) and six cases of ameloblastic fibroma (AF) were subjected to comparative analysis by the AgNOR technique, in order to determine a possible difference in cell proliferation index between these lesions. The mean AgNOR number of the mesenchymal component of AF was compared with its epithelial component and the difference was not found to be statistically significant. The mean AgNOR index of the AF group was significantly higher than that of the OM group. Moreover, the mesenchymal component of AF demonstrated increased AgNOR numbers compared with that of OM (P<0.05). These results suggest that the epithelial and mesenchymal components of AF may have similar cell proliferative activity. However, the cell proliferative index of this lesion seems to be higher than that of OM.

    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.

    We apply the $Om$ diagnostic to models for dark energy based on scalar fields. In case of the power law potentials, we demonstrate the possibility of slowing down the expansion of the Universe around the present epoch for a specific range in the parameter space. For these models, we also examine the issues concerning the age of Universe. We use the $Om$ diagnostic to distinguish the $\\Lambda$CDM model from non minimally coupled scalar field, phantom field and generic quintessence models. Our study shows that the $Om$ has zero, positive and negative curvatures for $\\Lambda$CDM, phantom and quintessence models respectively. We use an integrated data base (SN+Hubble+BAO+CMB) for bservational analysis and demonstrate that $Om$ is a useful diagnostic to apply to observational data.

  13. 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.

  15. 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.

  17. Impact of EfOM size on competition in activated carbon adsorption of organic micro-pollutants from treated wastewater.

    2014-11-15

    The competitive impacts of different fractions of wastewater treatment plant effluent organic matter (EfOM) on organic micro-pollutant (OMP) adsorption were investigated. The fractionation was accomplished using separation by nanofiltration (NF). The waters resulting from NF were additionally treated to obtain the same dissolved organic carbon (DOC) concentrations as the initial water. Using size exclusion chromatography (LC-OCD) it could be shown that the NF treatment resulted in an EfOM separation by size. Adsorption tests showed different competitive effects of the EfOM fractions with the OMP. While large EfOM compounds that were retained in NF demonstrated a reduced competition as compared to the raw water, the NF-permeating EfOM compounds showed an increased competition with the majority of the measured OMP. The effects of small size EfOM are particularly negative for OMP which are weak/moderate adsorbates. Adsorption analysis was carried out for the differently fractionized waters. The small sized EfOM contain better adsorbable compounds than the raw water while the large EfOM are less adsorbable. This explains the observed differences in the EfOM competitiveness. The equivalent background compound (EBC) model was applied to model competitive adsorption between OMP and EfOM and showed that the negative impacts of EfOM on OMP adsorption increase with decreasing size of the EfOM fractions. The results suggest that direct competition for adsorption sites on the internal surface of the activated carbon is more substantial than indirect competition due to pore access restriction by blockage. Another explication for reduced competition by large EfOM compounds could be the inability to enter and block the pores due to size exclusion.

    2000-12-01

    The oxygen-to-metal (O/M) ratio is one of the most critical parameters of nuclear fuel fabrication, and its measurement is closely monitored for manufacturing process control and to ensure the service behavior of the final product. Thermogravimetry is the most widely used method, the procedure for which has remained largely unchanged since its development some thirty years ago. It was not clear to us, however, that this method is still the optimum one in light of advances in instrumentation, and in the current regulatory environment, particularly with regard to waste management and disposal. As part of the MOX fuel fabrication program at Los Alamos, we conducted a comprehensive review of methods for O/M measurements in UO{sub 2}, PuO{sub 2} and mixed oxide fuels for thermal reactors. A concerted effort was made to access information not available in the open literature. We identified approximately thirty five experimental methods that (a) have been developed with the intent of measuring O/M, (b) provided O/M indirectly by suitable reduction of the measured data, or (c) could provide O/M data with suitable data reduction or when combined with other methods. We will discuss the relative strengths and weaknesses of these methods in their application to current routine and small-lot production environment.

    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.

    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.

    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.

    2001-09-01

    Full Text Available Hvilken rolle spiller medierne i hverdagslivet blandt etniske minoriteter i Danmark? Lidt firkantet kan man spørge: er mennesker af anden etnisk oprindelse mere integrerede, når de foretrækker dansk produceret fjern- syn, end når de foretrækker oprindelseslandets tv? Kultursociologen Connie Carøe Christiansen har i denne artikel trukket nogle af pointerne op fra en undersøgelse, som Danmarks Radio bestilte hos Socialforsk- ningsinstituttet om netop nogle af ovenstående spørgsmål. Carøe, en af rapportens hovedforfattere, analyserer medieforbruget hos etniske mino- riteter i Danmark i lyset af diskussioner om multikulturalisme og social integration. Artiklen er således inspireret af diskussioner om transnationa- lisme og diaspora-identiteter.

  14. 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

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

    KAUST Repository

    Wei, Chunhai

    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.

    2004-09-01

    Full Text Available Artiklen præsenterer forskellige aspekter af markedskommunikation set som autokommunikation – det vil sige kommunikation om og til af- sender selv. Moderne marketing er grundlagt på ideen om, at virksom- heder kun overlever i længden, hvis de er opmærksomme på marke- dets ønsker og behov, og branchen arbejder ud fra en ideel forståelse om responsivitet og dialog med kunder og omverden. Artiklen påpeger imidlertid, at den moderne forbruger – eller modtager – oftest forholder sig blasert eller ligegyldigt til reklamens budskaber, hvorimod både rek- lamebureauerne og deres kunder er højinvolverede i at omsætte bud- skaberne til symbolsk værdiskabelse inden for virksomhedernes egne rammer. I et ledelsesperspektiv betyder det for det første, at visioner og holdninger bliver forlenet med en særlig autoritet og forpligtelse for virksomheden, når disse visioner kommunikeres offentligt gennem et eksternt medie. Intern kommunikation får simpelthen en større gennem- slagskraft, når den sendes ud af huset, og artiklen viser med en række eksempler, hvorledes reklamer kan anspore medarbejderne til korps- ånd og hensigtsmæssig adfærd i ’sandhedens øjeblik’ – mødet med kunden.

  12. Effects of effluent organic matter (EfOM) on the removal of emerging contaminants by ozonation.

    Science.gov (United States)

    Cai, Ming-Jhih; Lin, Yi-Pin

    2016-05-01

    Removal of emerging contaminants in wastewater treatment is essential to ensure the ecological health of the receiving water bodies. Ozonation is a promising technology to achieve this purpose but important wastewater characteristics affecting the optimal removal efficiency need to be elucidated. Secondary effluents contain effluent organic matter (EfOM), which can react directly with ozone as well as react as the initiator, promoter and inhibitor in the hydroxyl radical (.OH) chain reactions resulting from ozone decomposition. These different reaction modes of EfOM, coupled with alkalinity and pH value, collectively determine the ozone and .OH exposures and the degradation of pharmaceutical compounds by ozonation. In this study, we determined the rate constants of EfOM collected from two municipal wastewater treatment plants in terms of direct ozone reaction, initiation, promotion and inhibition at various pH values (pH 6.0-7.5) and temperatures (10-30 °C). The rate constants of direct reaction and initiation generally increased with the increasing pH value while the rate constants of promotion and inhibition did not vary significantly. All rate constants increased with the increasing temperature. The removal of ibuprofen, acetylsulfamethoxazole and metoprolol in diluted secondary effluent by ozonation can be fairly-well modeled by using the determined rate constants of EfOM.

    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.

    Background Environmental factors play a major role on atopic dermatitis (AD) which shows a constant rise in prevalence in western countries over the last decades. 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. Objective 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. Methods 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. Results 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. Conclusions Results show an adjuvant therapeutic effect of a well standardized bacterial lysate OM-85 on established AD. PMID:28333952

A partir de l’énorme littérature épidémiologique sur le sujet, on peut conclure que la consommation de poisson « gras » ou d’oméga 3 à longue chaîne a un effet protecteur sur la mortalité coronaire et plus généralement sur les maladies cardiovasculaires. Il existe des indications en faveur d’un effet similaire de l’apport en alphalinolénique (ALA.

    2009-02-15

    Computed tomography (CT) and in particular multi-detector row computed tomography (MDCT), also known as multislice CT (MSCT), is ideally suited for detecting pancreatic tumors because of the high spatial resolution. The method of choice is hydro-CT which involves distension of the stomach and duodenum by administration of 1-1.5 l water as a negative contrast medium under medically induced hypotension by administration of buscopan. The patient is laid on the right side at an angle of 30-45 in order to obtain an artefact-free image of the close anatomical relationship around the pancreas head. In addition, curved MPRs or in rare cases 3D reconstructions could be very helpful in identifying the critical anatomic tumor site in the neighbourhood of the visceral vessel system. After the correct diagnosis of an adenocarcinoma has been made only 20% of all patients are shown to have a surgically resectable disease, but the overall survival rate is significantly higher after resection in combination with a multimodal tumor therapy strategy. The reason is that the correct diagnosis of the resectability of the tumor is one of the main criteria for overall survival of these patients. Currently practically all pancreatic tumors can be detected using MDCT and the detection rate varies between 70% and 100% (most recent literature references give a sensitivity of 89% and specificity up to 99%). In some rare cases the differentiation between focal necrotizing pancreatitis and pancreatic carcinoma can be difficult even with sophisticated protocols. Resectability can be correctly diagnosed with MDCT with a sensitivity of 94% and a specificity of 89%. MDCT is an ideal tool for the detection of neuroendocrine tumors, metastases and for the differentiation of cystic pancreatic lesions such as pseudocysts, microcystic adenomas or intraductal papillary mucinous neoplasms (IPMN). Particularly, the differentiation of the latter into benign, borderline or malignant transformation is not

    Oxymatrine (OM)/N-succinyl-chitosan ( Suc-Chi, with a degree of substitution being 0. 32 ) was synthesized via the ring-opening reaction of succinic anhydride with chitosan in dimethyl sulfoxide. OM-loaded Suc-Chi nanoparticles were prepared by an ionotropic gelation process and OM was quantified via the HPLC method. The influences of the initial OM concentration on the nanoparticle characteristics and OM release behavior were evaluated. The nanoparticles were found to have a mean diameter within a range of 267-392 nm, a positive surface charge, and a zeta potential in the range of 19-27 mY. The formulation with an initial OM concentration of 100 μg/mL provided the highest loaded capacity(0.77%) and the highest extent of the released OM (68% at 24 h), suggesting the possibility to achieve a therapeutic dose. According to the data obtained, this Suc-Chi-based nanotechnology will open up new and interesting prospects for the development of new anticancer drugs.

  1. Loop Quantum effects on Om-diagnostic and its Cosmological Implications

    CERN Document Server

    Rudra, Prabir

    2014-01-01

    In this paper we study the Loop quantum effects on the \\textit{Om} diagnostic and subsequently on the universe. We reconstruct the \\textit{Om} diagnostic in the background of Loop quantum gravity and then study the behaviour of various Chaplygin gas dark energy models using the modified diagnostic in a comparative scenario. The trajectories discriminate the various dark energy models from each other both in the Einstein gravity as well as Loop quantum gravity. The Loop quantum effects are also clearly noticeable from the trajectories in past, present and future universe. We see that the Loop quantum deviations are highly pronounced in the early universe, but alleviates as we tend towards the present universe and continue to decay in future. Thus it puts a big question on the effectiveness and consequently the suitability of loop quantum cosmology to explain the future universe.

    A new approach has been initiated at JPL to fabricate thin-film, high efficiency GaAs solar cells on low-cost, single-crystal Si substrates having a thin CVD interlayer of Ge to minimize the lattice and thermal expansion mismatch. For initial experiments, n(+)/p GaAs cells were grown by OM-CVD on single-crystal GaAs and Ge wafers. Details of the growths and performance results will be presented. Subsequently, a combined epitaxial structure of OM-CVD GaAs on a strongly adherent Ge interlayer on (100) Si was grown. This is the first report of the successful growth of this composite structure. Low module costs projected by JPL SAMICS methodology calculations and the potential for 400-600W/kg space solar arrays will be discussed.

    2010-01-15

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

    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.

    2016-01-01

    We investigate thermodynamics and Phase transition of the Reissner-Nordstr\\"om black hole surrounded by quintessence. Using thermodynamical laws of black holes, we derive the expressions of some thermodynamics quantities for the Reissner-Nordstr\\"om black hole surrounded by quintessence. The variations of the temperature and heat capacity with the entropy were plotted for different values of the state parameter related to the quintessence, $\\omega_{q}$, and the normalization constant related to the density of quintessence $c$. We show that when varying the entropy of the black hole a phase transition is observed in the black hole. Moreover, when increasing the density of quintessence, the transition point is shifted to lower entropy and the temperature of the black hole decreases.

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

    2001-07-01

    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.)

    OM-X® is a hand-made and naturally manufactured probiotic supplement. This fermented food product is made from vegetables, fruits, seaweeds and mushrooms, using 12 strains of lactic acid bacteria and bifidobacteria. OM-X® is also known to have beneficial health properties, and some of its components show effects on antigen (Ag)-stimulated degranulation activity, indicating that OM-X® may be useful in the treatment of allergy responses and symptoms. In this study, we evaluated the inhibitory effects of OM-X® on Ag-stimulated degranulation in rat basophilic leukemia RBL-2H3 cells, clarified the underlying mechanisms, and determined the active compounds in OM-X® for suppression of degranulation. Treatment with OM-X® gradually suppressed Ag-stimulated degranulation throughout the maturation period. OM-X® also gradually produced melanoidins by lactic acid bacterial fermentation during the maturation process. There was a high correlation between the suppression levels of Ag-stimulated degranulation and the browning of OM-X®. Furthermore, the inhibition of Ag-stimulated degranulation by OM-X® was found to be partially due to the direct inactivation of NADPH oxidase. To elucidate the in vivo effects of OM- X®, type I allergy model mice were orally administered with OM-X®, and the passive cutaneous anaphylaxis (PCA) reaction was measured. OM-X® intake remarkably suppressed the PCA reaction. Taken together, our findings suggest that OMX® could be a beneficial food to ameliorate allergic reactions.

    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

  17. Ependymal tumors.

    2003-12-01

    Ependymal tumors are rare malignancies that arise from the cells that line the ventricles and central canal of the spinal cord. Although they are more common in children, adults may also be effected by ependymal tumors. Prognosis is dependent on tumor location, histology, especially for myxopapillary tumors that tend to occur in the lumbar spine, extent of surgical resection, and stage of disease. Standard therapy consists of complete resection when feasible. The exact role of adjuvant radiotherapy in patients with radiographically confirmed complete resection is poorly defined. Patients with known residual disease may benefit from local radiation therapy, but the extent of radiation field and total dose are controversial. Even in patients treated with involved field radiotherapy, most relapses occur within the original tumor bed, thus local control remains the biggest obstacle to effective therapy. Chemotherapy has little impact against this tumor and has no role in the adjuvant setting, outside of a well designed clinical trial, with the possible exception of children younger than 5 years in an effort to delay radiation. A minority of patients may respond to one of several chemotherapy regimens at the time of recurrence, but the impact of this therapy is limited. Newer treatment strategies are needed.

  1. Simultaneous removal of phosphorus and EfOM using MIEX, coagulation, and low-pressure membrane filtration.

    2015-01-01

    The feasibility of using magnetic ion exchange (MIEX) treatment, in-line alum coagulation, and low-pressure membrane filtration was investigated for the simultaneous removal of total phosphorus (TP) and effluent organic matter (EfOM) from biologically treated wastewater. The focus was also placed on minimizing fouling of polyvinylidene fluoride and polyethersulfone membranes, which are the most commonly used low-pressure membranes in new and retrofit wastewater treatment plants. MIEX alone was effective for the removal of EfOM, and MIEX plus a small alum dose was very effective in removing both EfOM and TP. MIEX removed phosphorus, but organic acids in EfOM were preferentially removed, and the effects of competing anions on the removal of EfOM were insignificant. All the pretreatment strategies decreased the resistance to filtration. The greatest decrease in fouling was achieved by using MIEX (15 mL L⁻¹) plus a very low dose of alum (∼0.5 mg Al L⁻¹). Sweep floc coagulation using alum and without MIEX also significantly decreased fouling but did not effectively remove EfOM and produced high floc volume that could be problematic for inside-out hollow-fibre modules. The addition of these reagents into rapid mix followed by membrane filtration would provide operational simplicity and could be easily retrofitted at existing membrane filtration facilities.

  2. OM14 is a mitochondrial receptor for cytosolic ribosomes that supports co-translational import into mitochondria.

    It is well established that import of proteins into mitochondria can occur after their complete synthesis by cytosolic ribosomes. Recently, an additional model was revived, proposing that some proteins are imported co-translationally. This model entails association of ribosomes with the mitochondrial outer membrane, shown to be mediated through the ribosome-associated chaperone nascent chain-associated complex (NAC). However, the mitochondrial receptor of this complex is unknown. Here, we identify the Saccharomyces cerevisiae outer membrane protein OM14 as a receptor for NAC. OM14Δ mitochondria have significantly lower amounts of associated NAC and ribosomes, and ribosomes from NAC[Δ] cells have reduced levels of associated OM14. Importantly, mitochondrial import assays reveal a significant decrease in import efficiency into OM14Δ mitochondria, and OM14-dependent import necessitates NAC. Our results identify OM14 as the first mitochondrial receptor for ribosome-associated NAC and reveal its importance for import. These results provide a strong support for an additional, co-translational mode of import into mitochondria.

    Full Text Available Germ cell tumors of the testes represent a unique paradigm of diseases which can be cured even in extremely advanced phase. Unfortunately, this makes them unique among adult solid tumors. Seminoma and non seminoma are relatively rare with approximatively 25,000 patients in Europe per year, but numbers are increasing world wide. Different strategies are needed depending on stage and prognostic scores. Seminoma is extremely sensitive to radiation therapy and chemotherapy, while all germ cell tumors show a very good response to chemotherapy. Clinical stage I seminoma is currently treated with radiation, single course carboplatin or surveillance policy. Clinical stage I non seminoma can also be approached with different strategies such as retroperitoneal lymph node dissection, observation or one-two courses of standard chemotherapy. Stage II seminoma may be treated with either radiation or chemotherapy, while for all advanced stages chemotherapy is mandatory. Since the mid-eighties PEB (Cisplatin, Etoposide and Bleomycin is the regimen of choice and no other schedule has proved superior in terms of efficacy. Surgery on the residual disease is crucial to the whole strategy and should be performed or attempted in all cases. Consequently, the correct treatment strategy for these tumors does not depend only on the ability of a single physician, but on a skilled team specialized in this particular tumor. Second line therapies (VeIP, PEI, TIP can cure 25%–40% of patients, but improved strategies for resistant tumors are desperately needed. High-dose chemotherapy has shown very good results in some studies while being less impressive in others. In any case, it should remain an option for relapsing patients and could be used in some cases of upfront chemotherapy in patients with slow marker decline, but this should only be considered in referring centers.

    The translation of well established psychometric tools from English into Xhosa may assist in improving access to psychological services for Xhosa speakers. The aim of this study was to translate the Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM), a measure of general distress and dysfunction developed in the UK, into Xhosa for use at South African university student counselling centres. The CORE-OM and embedded CORE-10 were translated into Xhosa using a five-stage translation design. This design included (a) forward-translation, (b) back-translation, (c) committee approach, (d) qualitative piloting, and (e) quantitative piloting on South African university students. Clinical and general samples were drawn from English-medium South African universities. Clinical samples were generated from university student counselling centres. General student samples were generated through random stratified cluster sampling of full-time university students. Qualitative feedback from the translation process and results from quantitative piloting of the 34-item CORE-OM English and Xhosa versions supported the reduction of the scale to 10 items. This reduced scale is referred to as the South African CORE-10 (SA CORE-10). A measurement and structural model of the SA CORE-10 English version was developed and cross-validated using an English-speaking university student sample. Equivalence of this model with the SA CORE-10 Xhosa version was investigated using a first-language Xhosa-speaking university sample. Partial measurement equivalence was achieved at the metric level. The resultant SA CORE-10 Xhosa and English versions provide core measures of distress and dysfunction. Additional, culture- and language-specific domains could be added to increase sensitivity and specificity.

    An exponential model of nonlinear electrodynamics coupled with the gravitational field is analyzed. It was shown that weak, dominant, and strong energy conditions are satisfied. We obtain corrections to Coulomb's law at $r\\rightarrow\\infty$. It was demonstrated that electric-magnetic duality between ${\\cal F}$ and ${\\cal P}$ frames is violated. The asymptotic black hole solution at $r\\rightarrow \\infty$ is found that contains corrections to the Reissner-Nordstr\\"om solution. The electromagnetic mass of the black hole is calculated, expressed through the parameter $\\beta$ of the model.

    We study the circular motion of charged test particles in the gravitational field of a charged mass described by the Reissner-Nordstr\\"om spacetime, focusing on the physical differences between black holes and naked singularities. We perform the most complete classification of circular orbits for different sets of the main physical parameters, and study numerically the behavior of the angular momentum and energy of the charged test particle. Our analysis shows in an alternative manner that the behavior of circular orbits can be used to distinguish between black holes and naked singularities.

    We investigate the circular motion of charged test particles in the gravitational field of a charged mass described by the Reissner-Nordstr\\"om (RN) spacetime. We study in detail all the spatial regions where circular motion is allowed around either black holes or naked singularities. The effects of repulsive gravity are discussed by finding all the circles at which a particle can have vanishing angular momentum. We show that the geometric structure of stable accretion disks, made of only test particles moving along circular orbits around the central body, allows us to clearly distinguish between black holes and naked singularities.

    We consider the brane universe in the bulk background of the topological Reissner-Nordstr\\"om de Sitter black holes. We show that the thermodynamic quantities (including entropy) of the dual CFT take usual special forms expressed in terms of Hubble parameter and its time derivative at the moment, when the brane crosses the black hole horizon or the cosmological horizon. We obtain the generalized Cardy-Verlinde formula for the CFT with an charge and cosmological constant, for any values of the curvature parameter $k$ in the Friedmann equations.

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

    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

    2016-06-01

    Superior Sulcus Tumors, frequently termed as Pancoast tumors, are a wide range of tumors invading the apical chest wall. Due to its localization in the apex of the lung, with the potential invasion of the lower part of the brachial plexus, first ribs, vertebrae, subclavian vessels or stellate ganglion, the superior sulcus tumors cause characteristic symptoms, like arm or shoulder pain or Horner's syndrome. The management of superior sulcus tumors has dramatically evolved over the past 50 years. Originally deemed universally fatal, in 1956, Shaw and Paulson introduced a new treatment paradigm with combined radiotherapy and surgery ensuring 5-year survival of approximately 30%. During the 1990s, following the need to improve systemic as well as local control, a trimodality approach including induction concurrent chemoradiotherapy followed by surgical resection was introduced, reaching 5-year survival rates up to 44% and becoming the standard of care. Many efforts have been persecuted, also, to obtain higher complete resection rates using appropriate surgical approaches and involving multidisciplinary team including spine surgeon or vascular surgeon. Other potential treatment options are under consideration like prophylactic cranial irradiation or the addition of other chemotherapy agents or biologic agents to the trimodality approach.

  12. Proof of linear instability of the Reissner-Nordstr\\"om Cauchy horizon under scalar perturbations

    CERN Document Server

    Luk, Jonathan

    2015-01-01

    It has long been suggested that solutions to linear scalar wave equation $$\\Box_g\\phi=0$$ on a fixed subextremal Reissner-Nordstr\\"om spacetime with non-vanishing charge are generically singular at the Cauchy horizon. We prove that generic smooth and compactly supported initial data on a Cauchy hypersurface indeed give rise to solutions with infinite nondegenerate energy near the Cauchy horizon in the interior of the black hole. In particular, the solution generically does not belong to $W^{1,2}_{loc}$. This instability is related to the celebrated blue shift effect in the interior of the black hole. The problem is motivated by the strong cosmic censorship conjecture and it is expected that for the full nonlinear Einstein-Maxwell system, this instability leads to a singular Cauchy horizon for generic small perturbations of Reissner-Nordstr\\"om spacetime. Moreover, in addition to the instability result, we also show as a consequence of the proof that Price's law decay is generically sharp along the event horiz...

    The mitochondrial cytochrome c oxidase assembles in the inner membrane from subunits of dual genetic origin. The assembly process of the enzyme is initiated by membrane insertion of the mitochondria-encoded Cox1 subunit. During complex maturation, transient assembly intermediates, consisting of structural subunits and specialized chaperone-like assembly factors, are formed. In addition, cofactors such as heme and copper have to be inserted into the nascent complex. To regulate the assembly process, the availability of Cox1 is under control of a regulatory feedback cycle in which translation of COX1 mRNA is stalled when assembly intermediates of Cox1 accumulate through inactivation of the translational activator Mss51. Here we isolate a cytochrome c oxidase assembly intermediate in preparatory scale from coa1Δ mutant cells, using Mss51 as bait. We demonstrate that at this stage of assembly, the complex has not yet incorporated the heme a cofactors. Using quantitative mass spectrometry, we define the protein composition of the assembly intermediate and unexpectedly identify the putative methyltransferase Oms1 as a constituent. Our analyses show that Oms1 participates in cytochrome c oxidase assembly by stabilizing newly synthesized Cox1.

  14. Non-Abelian clouds around Reissner-Nordstr\\"om black holes: the existence line

    CERN Document Server

    Radu, Eugen; Yang, Yisong

    2016-01-01

    A known feature of electrically charged Reissner-Nordstr\\"om-anti-de Sitter planar black holes is that they can become unstable when considered as solutions of Einstein--Yang-Mills theory. The mechanism for this is that the linearized Yang-Mills equations in the background of the Reissner-Nordstr\\"om (RN) black holes possess a normalizable zero mode, resulting in non-Abelian (nA) magnetic clouds near the horizon. In this work we show that the same pattern may occur also for asymptotically flat RN black holes. Different from the anti-de Sitter case, in the Minkowskian background the prerequisite for the existence of the nA clouds is $i)$ a large enough gauge group and $ii)$ the presence of some extra interaction terms in the matter Lagrangian. To illustrate this mechanism we present two specific examples, one in four and the other in five dimensional asymptotically flat spacetime. In the first case, we augment the usual $SU(3)$ Yang-Mills Lagrangian with higher order (quartic) curvature term, while for the sec...

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

    Energy Technology Data Exchange (ETDEWEB)

    Rowley, C.W.

    1996-12-01

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

    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.

    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.

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.

  13. Bounded energy waves on the black hole interior of Reissner-Nordstr\\"om-de Sitter

    CERN Document Server

    Costa, João L

    2016-01-01

    Motivated by the Strong Cosmic Censorship Conjecture, in the presence of a cosmological constant, we consider solutions of the scalar wave equation $\\Box_g\\phi=0$ on fixed subextremal Reissner--Nordstr\\"om--de Sitter backgrounds $({\\mathcal M}, g)$, without imposing symmetry assumptions on $\\phi$. We provide a sufficient condition, in terms of surface gravities and a parameter for an exponential decaying Price law, for a local energy of the waves to remain bounded up to the Cauchy horizon. The energy we consider controls, in particular, regular transverse derivatives at the Cauchy horizon; this allows us to extend the solutions with bounded energy, to the Cauchy horizon, as functions in $C^0\\cap H^1_{loc}$. Our results correspond to another manifestation of the potential breakdown of Strong Cosmic Censorship in the positive cosmological constant setting.

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

    Science.gov (United States)

    Punjiya, Meera; Chung Hee Moon; Yu Chen; Sonkusale, Sameer

    2016-08-01

    Recent research activities in the area of low-cost sensing and diagnostics that are realized on cellulosic paper substrate are presented. First a three-dimensional origami paper-based analytical device (omPAD) with multiple electrochemical sensors, an integrated sample reservoir and tight integration with a custom CMOS potentiostat is presented. Second, an optical sensor array with built-in microfluidic channel for sample delivery is presented. The sensors are fabricated using a combination of wax printing and screen-printing using a solution based approach in ambient conditions without the need for expensive fabrication equipment or a cleanroom. Readout is based on using existing consumer grade electronic devices like flatbed scanner (for optical sensor) or custom designed CMOS potentiostat (for electrochemical sensors). Together the 3D paper-based analytical device with integrated sensor, microfluidics and portable readout instrumentation demonstrates a low-cost, self-contained system suitable for sensing and point-of-care diagnostics.

    We perform the two$-$point diagnostic for the $Om(z)$ function proposed by Sahni ${\\it et al}$ in 2014 for the Starobinsky and Hu & Sawicki models in $f(R)$ gravity. We show that the observed values of the $Omh^2$ function can be explained in $f(R)$ models while in LCDM the $Omh^2$ funticon is expected to be a redshift independent number. We perform the analysis for some particular values of $\\Omega_m^0$ founding a cumulative probability ($P(\\chi^2 \\leq \\chi^2_{{\\it model}})$) $P \\sim 0.16$ or $\\sim0.09$ for the better cases versus a cumulative probability of $P \\sim 0.98$ in the $\\Lambda$CDM scenario. We also show that these models present a characteristic signature around the interval between $z\\sim 2$ and $z\\sim 4$, that could be confronted with future observations using the same test.

    Full Text Available L’acide α-linolénique (ALA fait partie de la famille des acides gras dits oméga 3. Il est dit essentiel parce qu’il ne peut pas être synthétisé dans notre organisme et doit donc être fourni par l’alimentation. Les plantes, sous forme de fruits, de légumes verts, de graines ou d’huiles issues de ces graines constituent une source majeure d’ALA. Cette synthèse a pour but de rappeler l’importance relative des végétaux quant à leur capacité à nous fournir des acides gras essentiels. Elle vise à faire le point sur les différentes voies développées par l’industrie agroalimentaire et à envisager les développements futurs.

    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

    CERN Document Server

    Sanchis-Gual, Nicolas; Herdeiro, Carlos; Font, José A; Montero, Pedro J

    2016-01-01

    In a recent letter, we presented numerical relativity simulations, solving the full Einstein--Maxwell--Klein-Gordon equations, of superradiantly unstable Reissner-Nordstr\\"om black holes (BHs), enclosed in a cavity. Low frequency, spherical perturbations of a charged scalar field, trigger this instability. The system's evolution was followed into the non-linear regime, until it relaxed into an equilibrium configuration, found to be a $\\textit{hairy}$ BH: a charged horizon in equilibrium with a scalar field condensate, whose phase is oscillating at the (final) critical frequency. Here, we investigate the impact of adding self-interactions to the scalar field. In particular, we find sufficiently large self-interactions suppress the exponential growth phase, known from linear theory, and promote a non-monotonic behaviour of the scalar field energy. Furthermore, we discuss in detail the influence of the various parameters in this model: the initial BH charge, the initial scalar perturbation, the scalar field char...

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

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

    Cosmological reconstruction technique is applied to study the cosmology of the Einstein-Aether (EA) gravity. We reconstructed an analytical model of EA theory for a type of Hubble dependent dark energy density proposed by Granda and Oliveros. The reconstructed cosmological scale factors are comprised of power-law, future singular model, emergent scale factor, intermediate scale factor, a unified theory for matter and dark energy dominated phases and finally for a type of non-extensive exponential scale factor, the q-de Sitter scale factor. In each cosmological epoch, we reconstruct the Lagrangian of the vector part of theory $F(K)$. Furthermore, \\emph{Om} diagnostic analysis technique is applied to fit parameters using recent observational data, namely Type Ia Supernovae, BAO, and data of Hubble parameter.

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

    Full Text Available Studies on flora of fallow lands of the Podlaski Przełom Bugu mesoregion were carried out between 2001 and 2003 in the area of 77 localities, situated in 20 communes. A systematic list of fallow land flora was made and its variation with respect to occurrence frequency, biological spectrum, persistence and belonging to geographic-historical and sociological-ecological groups was analyzed. Flora of fallow lands of the Podlaski Przełom Bugu mesoregion includes 442 species included in 60 families and 241 botanical genera. The most numerous group comprises very rare, rare and quite frequent species. In the floristic composition of the analysed flora, apophytes (72.2% predominate over anthropophytes (2.8% as well as perennials (61% over ephemerals (39%. Considering the biological spectrum of flora, hemicryptophytes (49% and terophytes (32% predominate over other life forms. Forest and shrub species (18.5% as well as meadow (17% and xerothermic sward plants (17.4% have the largest share in the flora. The abundant occurrence of segetal (15.8% and long-lived ruderal communities (8.1% was also noted. Moreover, the occurrence of 25 species endangered with extinction in fallow land communities of the Południowopodlaska Lowland was noted.

    2009-12-01

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

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

    2013-01-01

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

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

Chaperone proteins associate with precursor proteins in the cytosol to maintain them in a translocation competent conformation and are recognized by Toc64 and Om64 that are located on the outer membrane of the target organelle. Heat shock proteins (Hsp70) and Hsp90 are two chaperones, which are known to play import roles in protein import. The C-termini of these chaperones are known to interact with the TPR domain of chloroplast Toc64 and mitochondrial Om64 in Arabidopsis thaliana (At). Using a molecular dynamics approach and binding energy calculations, we identify important residues involved in the interactions. Our findings suggest that the TPR domain from AtToc64 has higher affinity towards C-terminal residues of Hsp70. The interaction occurs as the terminal helices move towards each other enclosing the cradle on interaction of AtHsp70 with the TPR domain. In contrast, the TPR domain from AtOm64 does not discriminate between the C-termini of Hsp70 and Hsp90. These binding affinities are discussed with respect to our knowledge of protein targeting and specificity of protein import into endosymbiotic organelles in plant cells.

  19. Salivary Tick Cystatin OmC2 Targets Lysosomal Cathepsins S and C in Human Dendritic Cells

    Full Text Available To ensure successful feeding tick saliva contains a number of inhibitory proteins that interfere with the host immune response and help to create a permissive environment for pathogen transmission. Among the potential targets of the salivary cystatins are two host cysteine proteases, cathepsin S, which is essential for antigen- and invariant chain-processing, and cathepsin C (dipeptidyl peptidase 1, DPP1, which plays a critical role in processing and activation of the granule serine proteases. Here, the effect of salivary cystatin OmC2 from Ornithodoros moubata was studied using differentiated MUTZ-3 cells as a model of immature dendritic cells of the host skin. Following internalization, cystatin OmC2 was initially found to inhibit the activity of several cysteine cathepsins, as indicated by the decreased rates of degradation of fluorogenic peptide substrates. To identify targets, affinity chromatography was used to isolate His-tagged cystatin OmC2 together with the bound proteins from MUTZ-3 cells. Cathepsins S and C were identified in these complexes by mass spectrometry and confirmed by immunoblotting. Furthermore, reduced increase in the surface expression of MHC II and CD86, which are associated with the maturation of dendritic cells, was observed. In contrast, human inhibitor cystatin C, which is normally expressed and secreted by dendritic cells, did not affect the expression of CD86. It is proposed that internalization of salivary cystatin OmC2 by the host dendritic cells targets cathepsins S and C, thereby affecting their maturation.

    2003-09-01

    Full Text Available Navorsing rakende die toelating van studente tot studierigtings aan tersiêre instansies is aanvanklik primêr gefokus op ’n soeke na meganismes om die aantal risikostudente betekenisvol te verminder – ’n uiters komplekse aangeleentheid. Onlangse veranderings in die Suid-Afrikaanse samelewing noodsaak tersiêre inrigtings om innoverend oor hul eie aard en doelstellings te dink. Die fokus is tans veral op moontlike wyses om die tradisioneel agtergeblewe deel van die Suid-Afrikaanse samelewing ’n billiker kans te gee op toelating tot en die behaal van sukses aan tersiêre instansies. Die druk op tersiêre instansies om te sorg dat die demografie van die studentekorps aan tersiêre instansies meer verteenwoordigend van die algemene bevolking raak, neem hand-oor-hand toe. Keuring van studente in studierigtings soos medies, tandheelkunde, ingenieurswese en sielkunde sal waarskynlik in die afsienbare toekoms in die brandpunt bly, aangesien die verhouding swart : wit studente wat tot hierdie studierigtings toegelaat word, steeds heeltemal ontoereikend (ten koste van swart studente is en nie naastenby in lyn met die doelwitte wat deur regeringslui gestel word nie. Die navorsers ondersoek in die onderhawige artikel die prestasie van senaatsdiskresionêre studente aan die Fakulteit Opvoedkunde van die Universiteit van Pretoria en kom tot die gevolgtrekking dat nóg ’n minimum M-telling van 11, nóg ’n toelatingstoetspunt tersiêre prestasie akkuraat voorspel. Uitkomsgebaseerde Onderrig en veranderende wyses van assessering en ‘bepunting’ in Graad 12 maak die situasie ingewikkelder. ’n Nasionale tweejaarstrategie word bepleit om die eskalerende uitdaging van billike keuring en toelating tot tersiêre opleidingsinstansies te fasiliteer.

  17. Oral vaccine (OM-89) in the recurrent urinary tract infection prophylaxis: a realistic systematic review with meta-analysis.

    2016-05-01

    To evaluate the efficacy of Escherichia Coli extract (OM-89) in the prophylaxis of recurrent uncomplicated urinary tract infection (UTI) through a contemporary systematic review and meta-analysis. Inclusion criteria were double-blind randomized trials using orally administrated OM-89, 6mg daily, during three months with a minimum of three months of monitoring. Outcomes were the frequency of bacteriuria in 3 and 6 months, dysuria in 6 months and UTI in 6 months. PubMed, MEDLINE, Cochrane Collaboration and their key references. After analysis by three independent reviewers, 15 double-blind randomized trials were identified, 10 papers excluded due to methods flaws and 5 used for data analysis due to double blinding and reporting drop-outs. Among 5 selected studies the date of publication ranged from 1985 to 2005, totalizing 396 patients in the OM-89 group and 392 in the control group. Overall, there were 61 dropouts in the control group and 76 in the OM-89 group. As a major limitation there was no appropriate description of their methodologies and none of the studies described conflict of interest or commitment to the pharmaceutical industry. All studies were multi-centric, except for two, which showed no clarity on allocation concealment. All studies show benefit in favor of vaccine. Current literature on prospective randomized controlled trials evaluating the use of oral OM-89 vaccine in the recurrent UTI prophylaxis is of low quality, limited to the first six months only and with variable definition of bacteriuria and UTI. Although all studies show benefit in favor of vaccine, no robust trial was identified, resulting in a high heterogeneity in the data analyzed. Also, publication bias could not be excluded and future higher quality studies are warranted adding intermediate (>12 months) and long-term follow-up. Copyright © 2014 AEU.

  18. Forestillinger om spanskfaget: et kritisk blikk på lærebøker i spansk

    Directory of Open Access Journals (Sweden)

    Liv Eide

    2013-06-01

    Full Text Available Denne artikkelen retter et kritisk blikk på lærebøker i spanskfaget, og stiller spørsmålet om de ivaretar læreplanens målsetninger om at fremmedspråksfaget skal være et dannings- og kulturfag. Vi skal se at spanskfagets historie og utfordringer skiller seg vesentlig fra de to andre store fremmedspråkene i skolen: tysk og fransk, og det er grunn til å tro at læreboken står spesielt sterkt i spanskfaget. Videre vil vi se at det hersker en forestilling om det spanske språket som turistspråk og et språk man forbinder med populærkultur, og at det er disse forestillingene som ofte ligger til grunn for elevenes valg av språket. Deretter presenteres en analysemodell utviklet for å analysere læreboktekster, og generelle funn fra en undersøkelse av ni lærebøker fra fire ulike læreverk i spansk som er i bruk i den norske skolen. På bakgrunn av denne undersøkelsen vil jeg hevde at lærebøkene bekrefter elevens allerede eksisterende forestillinger om faget. Lærebøkenes verdensbilde utfordrer dermed ikke elevens eget verdensbilde, noe jeg mener et danningsfag bør gjøre. Ved hjelp av et konkret eksempel synliggjøres det også hvilke aspekter ved språkopplæringen elevene står i fare for å gå glipp av når undervisningen blir styrt av læreboken. Avslutningsvis argumenterer jeg for behovet for forskning på hvordan bøkene brukes i praksis, og på lærernes egne forestillinger om spanskfaget.

    Full Text Available OBJECTIVES: To estimate the pharmacoeconomical impact of preventing recurrent upper respiratory tract infections (URTIs with OM-85, a non-specific immunostimulating agent, in at-risk children. METHODS: Implementation of a decisional model. The evaluation of effectiveness (number of prevented URTIs/therapeutic cycle was based on weighted average of the results of four randomized, double-blind, placebo-controlled trials identified by literature reviewing. The clinical events considered in the model were natural resolution of the infection, onset of complications (acute otitis media, sinusitis, others and their evolution. Baseline event probabilities were derived by reviewing published data in the literature. URTI-related direct and indirect costs supported by patient, by Italian health system and by community were structured according with the principal guidelines and implemented with current Italian prices and tariffs. The cost/ effectiveness of OM-85 was calculated for five scenarios, differing in the number of therapeutic cycles, grade of patient co-payment and other secondary assumptions. Sensibility analyses were performed to evaluate the model robustness. RESULTS: Immunostimulation with one cycle of OM-85 prevented on average 1,60 URTI/patient in six months (RR = 0,515. In the basic scenario, this preventive action induced savings for 107,42 euro/patient in the perspective of the patient’s family, for 48,52 euro/patient in the perspective of Italian health system and for 231,26 in the community perspective. Sensibility analyses confirmed the robustness of basic scenario results. Threshold analyses showed that OM-85 prophylaxis is economically convenient as long as more than 7% of infections are prevented or global cost of one episode of URTI is greater than 10,00 euro. CONCLUSIONS: Non-specific immunotherapy with OM-85 induces a reduction in the incidence of URTIs in atrisk children with a concurrent saving for patient and health system.

    通过前掺杂法(PI)和浸渍法(IM)制备了氧化锰八面体分子筛(Octahedral Molecular Sieves,OMS-2)负载Pd(Pd/OMS-2)催化剂.采用X射线衍射(XRD)、H2-程序升温还原(H2-TPR)和N2-吸附/脱附等技术对样品进行了表征,研究了不同制备方法和不同Pd负载量对Pd/OMS-2催化剂催化氧化CO性能的影响,通过与载体OMS-2的比较研究了Pd/OMS-2催化剂的稳定性.结果表明,前掺杂法制备的Pd/OMS-2-PI催化剂活性明显优于浸渍法制备的Pd/OMS-2-IM催化剂,其T100分别为75℃和175℃.这与Pd/OMS-2-PI催化剂中OMS-2载体与Pd之间存在强相互作用有关.Pd负载量明显影响Pd/OMS-2-PI催化剂的催化活性,3Pd/OMS-2-PI催化剂(Pd=3.0wt%)催化活性最高,这是由于Pd掺杂进入OMS-2晶格结构,能活化晶格氧,而随Pd含量进一步增加,部分Pd分布在OMS-2表面.稳定性结果表明,Pd/OMS-2-PI稳定性明显优于OMS-2载体本身,这可能与Pd掺杂进入催化剂晶格,能较好稳定OMS-2结构密切相关.%Pd/OMS-2 catalysts were prepared by pre-incorporation (PI) and wet impregnation (IM) methods. The influences of prepared methods and Pd loading of catalysts on the catalytic activity for CO oxidation were examined. The stability of catalysts was also investigated to compare with OMS- 2. The samples were characterized by X-ray diffraction ( XRD), H2 temperaure programmed reduction ( H2-TPR) and N2-adsorption/desorption. The results showed that, compared with wet impregnation method, Pd/OMS-2-PI prepared from pre-incorporation method revealed the higher catalytic activity due to the stronger interaction between Pd and OMS- 2. The catalytic oxidation of CO over Pd/OMS-2-PI increased with Pd loading and reached maximum activity at 3wt% Pd. The Pd/OMS-2-PI catalyst showed significant improvement in stability with respect to the OMS-2 support. This may be due to the interaction between Pd and OMS, which maintains phase stabilty of OMS-2 support.

  1. Migrationsnarrativer: Fortællinger om den gode slægtning blandt vestindiske kvinder

    Directory of Open Access Journals (Sweden)

    Karen Fog Olwig

    2010-12-01

    Full Text Available Siden slaveriets ophør midt i 1800-tallet har Caribien været præget af en stærk migrationstradition. Forskere har påvist, at denne tradition har fået næring afhistorier om den succesrige returmigrant, som rig på penge og materielle goder vender tilbage efter år i udlandet. I denne artikel argumenterer jeg for, at disse historier indskriver sig i et 'mandligt' narrativ, der primært fokuserer på muligheden for at opnå social og økonomisk mobilitet gennem migration. Gennem en analyse af livshistorieinterviews med kvindelige returmigranter på den vestindiskeø Nevis viser jeg, at der parallelt med det mandlige narrativ findes et komplementært 'kvindeligt' narrativ, som omhandler den gode slægtning, der udvandrer for at hjælpe familien i hjemlandet ved forsendelser af penge, tøj og andre materiellegoder. Denne migrant kan derfor vende tilbage som et højt respekteret familiemedlem til trods for de beskedne materielle ressourcer, vedkommende selv besidder. Selv om de to narrativer knytter sig til henholdsvis mænd og kvinder, drager både mandlige og kvindelige migranter på dem, afhængigt af deres særligeerfaringer i udlandet og de specifikke aspekter af deres liv de beretter om. Analysen peger på, at narrativerne ikke er faktuelle redegørelser for migrantforløb, men snarere kulturelt specifikke måder hvorpå migranter skaber mening ogsammenhæng i deres liv. Ikke desto mindre er narrativerne med til at præge de forventninger og erfaringer, der knytter sig til migration, og de spiller derfor en vigtig rolle i de migrationsprocesser, der rent faktisk finder sted.Migration Narratives:Stories of the good Relative among Caribbean WomenSince the abolishment of slavery during the middle of the nineteenth century, the Caribbean has been characterized by a strong migration tradition.

    2006-07-01

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

We show that all the gauge invariant information in the metric and Maxwell field perturbations is encoded in the spacetime scalars $\\mathcal{F} =\\delta (F^*_{\\alpha \\beta} F^{\\alpha \\beta})$ and $\\mathcal{Q} =\\delta (\\tfrac{1}{48} C^*_{\\alpha \\beta \\gamma \\delta} C^{\\alpha \\beta \\gamma \\delta})$, where $C_{\\alpha \\beta \\gamma \\delta}$ is the Weyl tensor, $F_{\\alpha \\beta}$ the Maxwell field, a star denotes Hodge dual and $\\delta$ means first order variation. We show that the linearized Einstein-Maxwell equations are equivalent to a coupled system of wave equations for the fields$\\mathcal{F}$ and $\\mathcal{Q}$. For nonnegative cosmological constant we prove that $\\mathcal{F}$ and $\\mathcal{Q}$ are pointwise bounded on the static outer region. In the asymptotically AdS casethe dynamics depends on the bou...

  10. Regular black holes: Electrically charged solutions, Reissner-Nordstr\\"om outside a de Sitter core

    Lemos, José P S

    2011-01-01

    To have the correct picture of a black hole as a whole it is of crucial importance to understand its interior. The singularities that lurk inside the horizon of the usual Kerr-Newman family of black hole solutions signal an endpoint to the physical laws and as such should be substituted in one way or another. A proposal that has been around for sometime, is to replace the singular region of the spacetime by a region containing some form of matter or false vacuum configuration that can also cohabit with the black hole interior. Black holes without singularities are called regular black holes. In the present work regular black hole solutions are found within general relativity coupled to Maxwell's electromagnetism and charged matter. We show that there are objects which correspond to regular charged black holes, whose interior region is de Sitter, whose exterior region is Reissner-Nordstr\\"om, and the boundary between both regions is made of an electrically charged spherically symmetric coat. There are several ...

  11. The entropy emission properties of near-extremal Reissner-Nordstr\\"om black holes

    2016-01-01

    Bekenstein and Mayo have revealed an interesting property of evaporating $(3+1)$-dimensional Schwarzschild black holes: their entropy emission rates $\\dot S_{\\text{Sch}}$ are related to their energy emission rates $P$ by the simple relation $\\dot S_{\\text{Sch}}=C_{\\text{Sch}}\\times (P/\\hbar)^{1/2}$. Remembering that $(1+1)$-dimensional perfect black-body emitters are characterized by the same functional relation, $\\dot S^{1+1}=C^{1+1}\\times(P/\\hbar)^{1/2}$, Bekenstein and Mayo have concluded that, in their entropy emission properties, $(3+1)$-dimensional Schwarzschild black holes behave effectively as $(1+1)$-dimensional entropy emitters. One naturally wonders whether all black holes behave as simple $(1+1)$-dimensional entropy emitters? In order to address this interesting question, we shall study in this paper the entropy emission properties of Reissner-Nordstr\\"om black holes. We shall show, in particular, that the physical properties which characterize the neutral sector of the Hawking emission spectra of...

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

  13. Modtagerforskning og kulturstudier. Om kvantitativ og kvalitative tilgange i dansk medieforskning

    1988-08-01

    Full Text Available Dansk medieforskning går i mange henseender sine egne veje. Det gør sig også gældende i receptionsforskningen. Hvor forholdet mellem kvantitative og kvalitative metoder står på dagsordenen i den internationale debat om modtager forskningen, fokuseres der i den danske diskussion på forholdet mellem den æstetiske analyse af teksten og empiriske studier af modtager- nes forståelser og oplevelser. Gennem personsammenfald glider de to diskussioner imidlertid ind i hinanden. I denne artikel forsøger Jørgen Bang at rede trådene ud fra hinanden for derefter at vurdere, hvilke muligheder der ligger for en dialog mellem de forskellige forskningstraditioner. På den ene side argumenterer han for nødvendigheden i at forlade den traditionelle humanistiske kulturopfattelse, hvor der opereres med et ab- solut skel mellem kunst og kulturindustri, til fordel for en antropologiske kulturopfattelse, der fokuserer på mediernes funktion i forskellige befolkningsgruppers livssammenhæng. På den anden side ønsker han at fastholde den humanistiskeforståelse af, at medieteksten iscenesætter intersubjektive forestillinger blandt de seere/lyttere/læsere, som lader sig "fange ind" af den. På hvilke sociale, psykologiske og tekstuelle betingelser selve tilegnelser sker, mener han imidlertidig fortsat er et uafklaret spørgs- mål, som kun en empirisk orienteret modtagerforskning kan finde svar på.

    Full Text Available The aim of this trial was to determine the toxic effect of OMS-43 on spraymen and inhabitants. The spraying operation lasted for 30 successive days, and two teams consisting of 20 spraymen, 2 mixers, 4 foremen and team leaders were engaged in this operation. The operators were under systematic and closed clinical observation and cholinesterase determination (tintometric method during the operation as well as, in some cases, two months after. In spite of the rigid instructions given to the spraymen to follow the necessary precautions, there were 42 cases of clinical symptoms. In some individuals several relapses occurred during the operation. No complaints or cholinesterase depression was observed during the first 2- week exposure. The main clinical symptoms were headache, giddiness, nausea and abdominal cramps; some workers felt weakness. Diarrhea was reported among two cases and was treated with Enterovioform (Ciba.A drop in whole blood CHE was seen among both mixers accompanied by clinical symptoms. One of the mixers left his job when his CHE was depressed to 12.5. Out of 20 spraymen, 8 showed depression of CHE in some cases with clinical symptoms. This study showed that the use of Sumithion under local conditions (sub- tropics, hot dry season was safe for residents, but its toxic effect on operators should be considered and further toxicological investigations are requires under tropical conditions.

  16. Holographic entanglement entropies for Schwarzschild and Reisner-Nordstr\\"om spacetimes

    CERN Document Server

    Sun, Yuan

    2016-01-01

    The holographic entanglement entropies (HEE) associated with four dimensional Schwarzschild and Reisner-Nordstr\\"om spacetimes are investigated. Unlike the cases of asymptotically AdS spacetimes for which the boundaries are always taken at (timelike) conformal infinities, we take the boundaries at either large but finite radial coordinate (far boundary) or very close to the black hole event horizons (near horizon boundary). The reason for such choices is that such boundaries are similar to the conformal infinity of AdS spacetime in that they are all timelike, so that there may be some hope to define dual systems with ordinary time evolution on such boundaries. Our results indicate that, in the case of far boundaries, the leading order contribution to the HEEs come from the background Minkowski spacetime, however, the next to leading order contribution which arises from the presence of the black holes is always proportional to the black hole mass, which constitutes a version of the first law of the HEE for asy...

    Full Text Available Studiens syfte är att diskutera lärares uppfattningar om estetiska uttrycksformer i svenskämnet. De sätt på vilka svenskämnet konstrueras och rekonstrueras genom styrdokument, ämnestraditioner, lärarutbildning, skolkontext och lärares uppfattningar påverkar vilket svenskämne barn möter i skolan. Associationsintervjuer med utgångspunkt i åtta nyckelord genomfördes med sex lärare som undervisar elever som är 7-9 år gamla, i årskurs ett till tre.  Intervjuerna analyserades med kritisk diskursanalys. Studien visar en variation av undervisningspraktiker där några informanter framställer svenskämnet som ett färdighetsämne. Andra lärare beskriver ett erfarenhetsbaserat multimodalt svenskämne där estetiska uttrycksformer har legitimitet som didaktiska verktyg. Estetiska uttrycksformer ses av dessa lärare som vägar in i skriftspråket, de kompenserar för olikheter och skapar gemenskap. I studien framkommer hur estetiska uttrycksformer tilldelas både intrinsikala och instrumentella värden.

  18. Water isotope variations in the global ocean model MPI-OM

    2012-02-01

    Full Text Available The stable water isotopes H218O and HDO are incorporated as passive tracers into the oceanic general circulation model MPI-OM, and a control simulation under present-day climate conditions is analyzed in detail. Both δ18O and δD distributions at the ocean surface and deep ocean are generally consistent with available observations on the large scale. The modelled δD-δ18O relations in surface waters slightly deviates from the slope of the global meteoric water line in most basins, and a much steeper slope is detected in Arctic Oceans. The simulated deuterium excess of ocean surface waters shows small variations between 80° S and 55° N, and a strong decrease north of 55° N. The model is also able to capture the quasi-linear relationship between δ18O and salinity S, as well as δD and S, as seen in observational data. Both in the model results and observations, the surface δ–S relations show a steeper slope in extra-tropical regions than in tropical regions, which indicates relatively more addition of isotopically depleted water at high latitudes.

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

    Three ordered mesoporous siliceous (OMS) materials known as MCM41s-unmodified MCM-41C16 ("C16"), and two MCM41s with different surface functionalities: MCM-41C16-SH ("C16-SH") and MCM-41C16-NH2 ("C16-NH2")-were synthesized and studied by inverse gas chromatography in order to determine their acceptor-donor properties. The specific retention volumes of nonpolar and polar probes that were chromatographed on these ordered mesoporous silica adsorbents were evaluated under infinite dilution conditions. Two methods were employed to calculate the standard free energy of adsorption, ΔGads, of each chromatographed probe on the basis its specific retention volume. These ΔGads values were then employed to estimate the van der Waals contribution and the specific contribution of the free surface energy for each MCM41. DN values (donor numbers, based on the Gutmann scale) and AN* values (acceptor numbers, based on the Riddle-Fowkes scale) were employed to determine the values of parameters that characterize the ability of the MCM41s to act as electron acceptors (parameter: KA) and donors (parameter: KD). Considering the different compositions of the probes, each of which has different acceptor-donor properties, a new chromatographic test to supplement the Grob test is suggested.

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

    We present the results of a series of XMM-Newton EPIC and OM observations of Her X-1, spread over a wide range of the 35 day precession period. We confirm that the spin modulation of the neutron star is weak or absent in the low state - in marked contrast to the main or short-on states. During the states of higher intensity, we observe a substructure in the broad soft X-ray modulation below ~1keV, revealing the presence of separate peaks which reflect the structure seen at higher energies. The strong fluorescence emission line at ~6.4keV is detected in all observations (apart from one taken in the middle of eclipse), with higher line energy, width and normalisation during the main-on state. In addition, we report the detection of a second line near 7keV in 10 of the 15 observations taken during the low-intensity states of the system. This feature is rather weak and not significantly detected during the main-on state, when the strong continuum emission dominates the X-ray spectrum. Spin resolved spectroscopy j...

MÉTODOS: Foram avaliados dados de 118 crianças e adolescentes, com idade entre 2 e 19 anos, atendidos entre os anos de 2001 a 2009 no Ambulatório de Cardiologia Pediátrica Preventiva do Instituto de Cardiologia de Porto Alegre. As variáveis analisadas foram: peso, altura, idade e sexo. Estas foram classificadas quanto aos critérios peso/idade, estatura/idade e índice de massa corpórea (IMC. Os pontos de corte adotados foram de três curvas de crescimento OMS/2006, NCHS/1977, CDC/2000. RESULTADOS: Quanto ao critério peso/idade pelo NCHS, 18% das crianças foram classificadas com eutrofia e 82% com peso elevado; pelo CDC, 28% eutróficas e 72% peso elevado; e pela OMS, 16,0% com eutrofia e 84% com peso elevado. Segundo o IMC, foram classificadas com baixo peso 0,8% da população, segundo CDC e OMS; eutróficos 7,6% e 6,8%, sobrepeso 26,3% e 11,9%, e com obesidade 65,3% e 80,5%, pelo CDC e OMS, respectivamente. Quanto ao critério estatura/idade, não houve diferença significativa entre os referenciais; em média, 98,3% da população estudada apresentou estatura adequada para idade. CONCLUSÃO: Conclui-se que as novas curvas da OMS são mais sensíveis para identificar obesidade em uma população de risco, o que tem importantes implicações para o manejo preventivo e terapêutico.

    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.

    Om to år forventer Syddansk Universitet og DHI at komme igennem nåleøjet i OECD og få godkendt en testmetode, der kan afsløre skadevirkningerne på dyr fra både nye og allerede kendte kemiske stoffer som phthalater, vækstfremmere, kemiske filtre i solcremer og parabener. »Vores dyrearter skal...... phthalater eller parabener, begynder også de at danne vitellogenin. »Ved hjælp af testen kan vi altså afsløre om et kemikalie, som vi har en mistanke til, virker hormonforstyrrende. I værste fald udvikler alle fiskene sig til hunfisk - eller omvendt,« siger Henrik Holbech. Metoden kan undersøge for både...

    De 20 børn udtaler sig som individuelle personer, de anlægger varierede betragtninger, men fremdrager alligevel mange fælles vurderinger.Til spørgsmålet om hvad de har lært, hvad der har været spændende og mindre spændende kan de alle fortælle om interessante undervisningsforløb, hvor de er blevet engageret og optagede af indholdet. Men samtidigt med deres begejstring har de heller ikke svært ved at fremkomme med eksempler på kedelige og trivielle aktiviteter i skolen. Set i lyset af børnenes...

    Full Text Available Los tumores primarios del cerebro requieren un manejo multidisciplinario. En este artículo se presenta un modelo de tratamiento de los tumores más frecuentes del adulto, siendo el objetivo primordial alcanzar el equilibrio entre sobrevida y calidad de vida. Para este efecto, son agrupados según su clasificación de la Organización Mundial de la Salud (OMS y se analizan cirugía, radioterapia y quimioterapia según corresponda. Se discute el tratamiento de cada una de estas lesiones considerando el estado clínico del paciente, la localización y tamaño de la lesión y el riesgo de daño funcional del sistema nervioso. En especial, se considera la utilidad de diferentes técnicas que permiten proteger al cerebro durante el tratamiento.

  18. Tug of war for the Eastern Siberian oil pipeline; Touwtrekken om de Oost-Siberische oliepijpleiding

    toen oligarchen in staat waren om de controle over de olie-sector te nemen, met name bronnen in Oost-Siberie. Bijvoorbeeld Michael Chodorkovski omzeilde de Moskouse overheid in de voorgestelde bouw van een pijpleiding naar China. Zijn plannen waren alleen gericht op de belangen van zijn bedrijf, terwijl de Russische staat alleen maar een klein deel van de inkomsten zou krijgen. De nieuw opkomende Russische staat onder president Poetin bracht een einde aan dit project en koos voor een route die Rusland de kans zou geven om olie te exporteren naar Japan. De strijd voor deze pijpleiding en de uiteindelijke route biedt een interessante case study van de recente politieke veranderingen in Rusland. Bovendien illustreert het hoe de Russische staat opnieuw de controle kreeg over de energie-industrie en welke rol energie speelt in het buitenlandse economische beleid. Siberische energiebronnen kunnen Rusland helpen deel te nemen aan de economische opkomst van de Aziatisch-Pacifische regio. ESPO is een eerste stap op weg naar Siberie's potentieel en de politieke en economische positie van Rusland in Oost-Azie en daarbuiten te versterken. Vandaar dat de pijplijn een duidelijk signaal is van de economische heropleving in Rusland als een krachtige speler op het Euraziatische continent.

    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.
