    Cinq (5) facteurs physico-chimiques : concentration en carbonate de sodium, tempĂ©rature et durĂ©e de carbonatation, temps de digestion et pression, ont Ă©tĂ© Ă©tudiĂ©s simultanĂ©ment pour voir leur effet sur l’extrait d’agar de Gelidium spinosum. L’étude a mis en Ă©vidence l’influence plus ou moins importante dechacun de ces facteurs sur les rĂ©ponses recherchĂ©es (rendement d’extraction, force de gel, point de gĂ©lification et point de fusion). DiffĂ©rentes interactions plus ou moins importantes ont pu ĂȘtre Ă©galement mises en Ă©vidence entre les facteurs Ă©tudiĂ©s.Mots-clĂ©s : gelidium spinosum, facteurs influents, interactions, agar-agar, rendement, qualitĂ©

    Background: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR‐RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR‐RS‐2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence‐based findings of the document. Methods: ICAR‐RS presents over 180 topics in the forms of evidence‐based reviews with recommendations (EBRRs), evidence‐based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results: ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion: This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS

    The Case On Assessment Of Spilled Oil With Mixed Free Product In Seoul

    The purpose of this study is to assess sources of contamination by analyzing the free product and oil compounds in groundwater near the Subway Station, located adjacent to the Yongsan Garrison in Seoul, Republic of Korea. All of the samples collected twice were groundwater and free product in a monitoring well. Analysis items are TPH fingerprinting, pristine/phytane ratio, alkylbenzene pattern, PAH&alkyl PAH, antioxidant, icing inhibitor, PIANO, element(C, N, H), and sulfur. Using ratio of pristine/phytane, we were able to distinguished fuel type between kerosene and JP-8 samples, which was impossible by GC/FID pattern. Alkyl benzene pattern was very effective in distinguishing between JP-8 and kerosene. It is very important that 2,4-dimethyl-6-tert-butyl phenol, an antioxidant used only for JP-8, was detected in free product samples. The concentration of sulfur in kerosene fuel is much lower than that of JP-8, and the total contents of sulfur in environmental samples can be used to differentiate the fuel type of spilled oil between kerosene and JP-8. In conclusion, according to the result of a variety of analytical methods to find the source of spilled fuel, it had been found that the fuel type detected in the tunnel of subway station and monitoring wells outside of Yongsan Garrison and the monitoring wells inside of Yongsan Garrison are the same

    Measurement of W+W- production and search for the Higgs boson in pp collisions at root s=7 TeV

    No full text
    A measurement of W+W- production in pp collisions at root s = 7 TeV and a search for the Higgs boson are reported. The W+W- candidates are selected in events with two leptons, either electrons or muons. The measurement is performed using LHC data recorded with the CMS detector, corresponding to an integrated luminosity of 36 pb(-1). The pp -> W+W- cross section is measured to be 41.1 +/- 15.3 (stat) +/- 5.8 (syst) +/- 4.5 (lumi) ph. consistent with the standard model prediction. Limits on WW gamma and WWZ anomalous triple gauge couplings are set. The search for the standard model Higgs boson in the W+W- decay mode does not reveal any evidence of excess above backgrounds. Limits are set on the production of the Higgs boson in the context of the standard model and in the presence of a sequential fourth family of fermions with high masses. In the latter context, a Higgs boson with mass between 144 and 207 GeV/c(2) is ruled out at 95% confidence level. (C) 2011 CERN. Published by Elsevier B.V. All rights reserved
