Planetary Science Virtual Observatory architecture

In the framework of the Europlanet-RI program, a prototype of Virtual Observatory dedicated to Planetary Science was defined. Most of the activity was dedicated to the elaboration of standards to retrieve and visualize data in this field, and to provide light procedures to teams who wish to contribute with on-line data services. The architecture of this VO system and selected solutions are presented here, together with existing demonstrators

El ultrasonido como mucolítico y desinflamatorio en la sinusitis alérgica del adulto de 30-50 años

Debido a la particular situación geográfica de nuestra provincia, la presencia de sinusitis alérgica es una patología con alta incidencia. Los vientos provenientes del Pacífico pierden su humedad en la cordillera de Los Andes, llegando a nosotros de forma seca y caliente, generando lo que se conoce como viento Zonda. Estas condiciones predisponen a la población a padecer enfermedades respiratorias altas como son la rinitis alérgica y la sinusitis. En este trabajo se trata de demostrar la eficacia del ultrasonido (US) como complemento de la terapia médica en la sinusitis del adulto. Esta terapia se aplica en reemplazo de mucolíticos y desinflamatorios, que influyen sobre otros órganos del paciente dañándolos. Asimismo, se intenta demostrar si la desinflamación primeramente de los cornetes nasales, y con ello el infundíbulo, permite un drenaje más rápido del seno y su consecuente desinflamación. La muestra estudiada es de 30 pacientes, de ambos sexos, con edades de entre 30 y 50 años con sinusitis alérgica

The EPN-TAP protocol for the Planetary Science Virtual Observatory

A Data Access Protocol has been set up to search and retrieve Planetary Science data in general. This protocol will allow the user to select a subset of data from an archive in a standard way, based on the IVOA Table Access Protocol (TAP). The TAP mechanism is completed by an underlying Data Model and reference dictionaries. This paper describes the principle of the EPN- TAP protocol and interfaces, underlines the choices that have been made, and discusses possible evolutions.Comment: 21 pages.

Relación entre el dolor y la estabilidad lumbar

Independientemente de su patología de origen, la lumbalgia es una de las enfermedades que más variedad de síntomas presenta, razón por la cual en general se torna dificultoso conocer cuál es la estructura causante de los síntomas. Partimos de la idea de que una columna inestable siempre va a ser fuente de dolor independientemente del origen de dicho dolor. Con este proyecto intentamos mostrar que existe una correlación inversa entre dolor y estabilidad lumbar: esto significa afirmar que a menor estabilidad, mayor dolor. La realización de la investigación se justifica por varias razones: la lumbalgia genera ausentismo laboral, incapacidad y patologías a distancia de la columna lumbar como en cadera o rodilla. Además cabe destacar que muchas veces se realizan cirugías que podrían evitarse de existir tal relación, ya que sería un trabajo kinésico el de devolver calidad de vida a ese paciente. Es por ello que esta investigación se propone, como objetivo general, determinar una relación inversa entre estabilidad y dolor lumbar; y como objetivos específicos, medir el grado de dolor lumbar, incapacidad en AVD e indemnidad articular; valorar en qué grado los indicadores fuerza muscular, flexibilidad, control neuromuscular e indemnidad articular determinan la estabilidad lumbar; analizar en qué patología lumbar se relacionan directamente las variables estudiadas; proponer un instrumento que permita medir el control neuromuscular, en reemplazo del estabilizar biofeedback

Performance of the CMS Cathode Strip Chambers with Cosmic Rays

The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns

Performance and Operation of the CMS Electromagnetic Calorimeter

The operation and general performance of the CMS electromagnetic calorimeter using cosmic-ray muons are described. These muons were recorded after the closure of the CMS detector in late 2008. The calorimeter is made of lead tungstate crystals and the overall status of the 75848 channels corresponding to the barrel and endcap detectors is reported. The stability of crucial operational parameters, such as high voltage, temperature and electronic noise, is summarised and the performance of the light monitoring system is presented

Commissioning and performance of the CMS silicon strip tracker with cosmic ray muons

This is the Pre-print version of the Article. The official published version of the Paper can be accessed from the link below - Copyright @ 2010 IOPDuring autumn 2008, the Silicon Strip Tracker was operated with the full CMS experiment in a comprehensive test, in the presence of the 3.8 T magnetic field produced by the CMS superconducting solenoid. Cosmic ray muons were detected in the muon chambers and used to trigger the readout of all CMS sub-detectors. About 15 million events with a muon in the tracker were collected. The efficiency of hit and track reconstruction were measured to be higher than 99% and consistent with expectations from Monte Carlo simulation. This article details the commissioning and performance of the Silicon Strip Tracker with cosmic ray muons.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)
