"Table 2" of "Measurement of inclusive K*(892)0, Phi(1020) and K*2(1430)0 production in hadronic Z decays."
1996
SIG in (1/SIG) is the total hadronic cross section. The erros are statistical ones. The cross sections SIG(C=A), SIG(C=B), and SIG(C=C) obtained with A) both kaons identified, B) at least one kaon identified, and C) without requiring kaon identification.

Quantitative analysis of mixtures of metal-carbonyl complexes by Fourier-transform infrared spectroscopy: application to the simultaneous double immu…
1996
Abstract The feasibility of a double immunoassay of haptens by the nonisotopic carbonyl metalloimmunoassay (CMIA) method is demonstrated. Three different pairings of antiepileptic medications from the groups carbamazepine, diphenylhydantoin, and phenobarbital (for each of which a mono-CMIA is already available) were assayed by double CMIA. The assay method employs as tracers metal–carbonyl complexes that give very strong signals in the range of 1850–2200 cm −1 in the infrared spectrum, permitting quantitative analysis by Fourier-transform infrared spectroscopy. The fact that the signals are individually assignable and of comparable intensity permits quantitative analysis of mixtures of two …
Why braille reading is important and how to study it /Por qué es importante la lectura en braille y cómo estudiarla
2016
AbstractDespite its relevance in theoretical and practical terms, braille reading has received little attention from researchers. Awareness of the pros and cons of the different procedures used to examine braille reading is needed to facilitate the realization of systematic studies and to improve teaching methods in braille reading. This study provides a critical examination of braille reading methods and highlights key points for future studies on tactile reading.
Quality recognition as a prescriber against disinformation
2022
El contexto mediático híbrido y la infodemia han incrementado el peligro de la desinformación, sobre todo entre los jóvenes, que mayoritariamente consumen contenidos digitales. Este artículo tiene como objetivo conocer las competencias y habilidades para detectar contenidos de baja calidad vinculados con la desinformación por parte de estudiantes de Periodismo y Comunicación de Argentina, Chile y España. A partir de un doble estudio comparativo, por países y nivel de formación, se pretende determinar las destrezas de futuros periodistas en el reconocimiento de información falsa. A través de un cuestionario online, los participantes (N=300) evaluaron la calidad observada (mínima, media o exc…
Studying social media as semiotic technology: a social semiotic multimodal framework
2018
How do we study social media technology? While social semiotics provides an extensive toolkit for analysing multimodal texts and semiotic practices, the study of social media as semiotic technology poses a significant challenge to existing research methodologies. In this article, we present a social semiotic framework that allows us to describe in analytical details the multimodal meaning potentials offered by digital social media technology and connect these to multimodal text-making and semiotic practices while underscoring the role of technology. Our framework is organized around seven interrelated and inherently informed dimensions: (1) multimodality, (2) practice, (3) the social, (4) m…
Phytochemical Analysis and Cytotoxicity Towards Multidrug-Resistant Leukemia Cells of Essential Oils Derived from Lebanese Medicinal Plants
2012
Juniperus excelsa fruit essential oil as well as J. oxycedrus, Cedrus libani, and Pinus pinea wood essential oils have been obtained with yields between 2.2 ± 0.3 % to 3.4 ± 0.5 % and analyzed by gas chromatography. Sesquiterpenes mainly characterized C. libani and J. oxycedrus essential oils, while in P. pinea and J. excelsa, monoterpenes were the most abundant compounds. In J. oxycedrus, cis-calamenene (7.8 %), cuparene (3.8 %), and cis-thujopsenal (2.0 %) have been detected for the first time. The cytotoxic activity of these essential oils against drug-sensitive CCRF-CEM and multidrug-resistant P-glycoprotein-expressing CEM/ADR5000 leukemia cells has been investigated (IC₅₀ values: 29.46…
Alaraajojen luun mineraalipitoisuuden ja polven nivelruston väliset yhteydet postmenopausaalisilla naisilla
2011
Tämän poikkileikkaustutkimuksen tarkoituksena oli selvittää luuston (reisiluun kaula, lanneranka L2-L4) mineraalitiheysarvojen ja polven nivelruston (reisiluu, sääriluu) eheyttä kuvaavien dGEMRIC-arvojen välistä yhteyttä postmenopausaalisilla naisilla. Tutkimukseen rekrytoitiin 82 naista (keskimääräiseltä iältään 57,7 vuotta, SD 4,2) lehti-ilmoituksen perusteella. Sisäänottokriteerinä oli rtg:llä arvioidun Kellgren-Lawrence-luokituksen (K/L) mukaan ensimmäisen (K/L1) tai toisen (K/L2) asteen lievä polven nivelrikko. Reisiluun kaulan ja lannerangan (L2–L4) BMC-arvot mitattiin DXA-laitteistolla. Tutkimushenkilöillä ei ollut osteoporoosia, jonka kynnysarvona käytettiin T-arvoa >2,5. Tibian ja …
