Personiskās elektroniskās informācijas organizēšanas paradumi
2018
Bakalaura darba temats ir personiskās elektroniskās informācijas organizēšanas paradumi. Elektroniski glabājamo dokumentu skaits katru gadu pieaug, līdz ar to, tas meklēšana un kārtošana var aizņemt laiku, lai atvieglot šo procesu rodas nepieciešamība pēc elektronisko dokumentu organizēšanas izpētēs. Darba mērķis ir noskaidrot, kādi ir cilvēku personiskās elektroniskās informācijas organizēšanas paradumi. Bakalaura darba teorētisko bāzi veido sociāli kognitīvā teorija. Pētījumā tiek izmantotas kvalitatīvas pētniecības metodes – intervija un verbālais protokols. Pētījuma empīriskā bāze sastāv no apkopotiem interviju un verbālo protokolu rezultātiem. No respondentiem tika noskaidrots, kā viņi…
Vicisitudes demográficas en Vila-Real durante el siglo XV
2009
Utilizando las fuentes documentales conservadas en el Archivo Municipal de Vilareal nos aproximamos a la dinámica demográfica de dicha localidad, observando los incesantes intentos municipales por mantener un óptimo nivel poblacional pese a las hambrunas, las carestías, las mortalidades, la guerra, etc. También analizamos el incesante, y a la vez contradictorio, movimiento migratorio. Finalmente dedicamos unas líneas a la formación de la morería en 1489. (A)
Risk analysis in bioequivalence and biowaiver decisions
2013
This article evaluates the current biowaiver guidance documents published by the FDA, EU and WHO from a risk based perspective. The authors introduce the use of a Failure Mode and Effect Analysis (FMEA) risk calculation tool to show that current regulatory documents implicitly limit the risk for bioinequivalence after granting a biowaiver by reduction of the incidence, improving the detection and limiting the severity of any unforeseen bioinequivalent product. In addition, the authors use the risk calculation to expose yet unexplored options for future extension of comparative in vitro tools for biowaivers.
Filosofia e psicologia nel giovane De Sarlo (1887-1893)
2008
Il presente contributo è rivolto all’approfondimento dei primi anni dell’attività e della produzione di Francesco De Sarlo, a partire dall’anno della sua laurea in medicina nell’Ateneo napoletano, avvenuta nel 1887. Dopo avere esercitato la professione medica per alcuni anni, il giovane De Sarlo si è dedicato alla psichiatria e alla neurologia. A partire dal 1892/1893 ha insegnato filosofia nei licei, seppure aspirando a quello universitario; infatti, nel 1897 ha conseguito la libera docenza in Filosofia teoretica e tre anni dopo ha ottenuto il suo primo insegnamento nell’Istituto di Studi Superiori di Firenze. Si è prestata attenzione anche ai primi studi di De Sarlo, relativi agli anni 18…
Ten millennia of hepatitis B virus evolution
2021
Hepatitis B virus (HBV) has been infecting humans for millennia and remains a global health problem, but its past diversity and dispersal routes are largely unknown. We generated HBV genomic data from 137 Eurasians and Native Americans dated between ~10,500 and ~400 years ago. We date the most recent common ancestor of all HBV lineages to between ~20,000 and 12,000 years ago, with the virus present in European and South American hunter-gatherers during the early Holocene. After the European Neolithic transition, Mesolithic HBV strains were replaced by a lineage likely disseminated by early farmers that prevailed throughout western Eurasia for ~4000 years, declining around the end of the 2nd…
Nanosecond-level time synchronization of autonomous radio detector stations for extensive air showers
2016
To exploit the full potential of radio measurements of cosmic-ray air showers at MHz frequencies, a detector timing synchronization within 1 ns is needed. Large distributed radio detector arrays such as the Auger Engineering Radio Array (AERA) rely on timing via the Global Positioning System (GPS) for the synchronization of individual detector station clocks. Unfortunately, GPS timing is expected to have an accuracy no better than about 5 ns. In practice, in particular in AERA, the GPS clocks exhibit drifts on the order of tens of ns. We developed a technique to correct for the GPS drifts, and an independent method is used to cross-check that indeed we reach a nanosecond-scale timing accura…
A layer correlation technique for pion energy calibration at the 2004 ATLAS Combined Beam Test
2010
A new method for calibrating the hadron response of a segmented calorimeter is developed and successfully applied to beam test data. It is based on a principal component analysis of energy deposits in the calorimeter layers, exploiting longitudinal shower development information to improve the measured energy resolution. Corrections for invisible hadronic energy and energy lost in dead material in front of and between the calorimeters of the ATLAS experiment were calculated with simulated Geant4 Monte Carlo events and used to reconstruct the energy of pions impinging on the calorimeters during the 2004 Barrel Combined Beam Test at the CERN H8 area. For pion beams with energies between 20GeV…
The ATLAS Inner Detector commissioning and calibration
2010
The ATLAS Inner Detector is a composite tracking system consisting of silicon pixels, silicon strips and straw tubes in a 2 T magnetic field. Its installation was completed in August 2008 and the detector took part in data-taking with single LHC beams and cosmic rays. The initial detector operation, hardware commissioning and insitu calibrations are described. Tracking performance has been measured with 7.6 million cosmic-ray events, collected using a tracking trigger and reconstructed with modular pattern-recognition and fitting software. The intrinsic hit efficiency and tracking trigger efficiencies are close to 100%. Lorentz angle measurements for both electrons and holes, specific energ…
Readiness of the ATLAS liquid argon calorimeter for LHC collisions
2010
The ATLAS liquid argon calorimeter has been operating continuously since August 2006. At this time, only part of the calorimeter was readout, but since the beginning of 2008, all calorimeter cells have been connected to the ATLAS readout system in preparation for LHC collisions. This paper gives an overview of the liquid argon calorimeter performance measured in situ with random triggers, calibration data, cosmic muons, and LHC beam splash events. Results on the detector operation, timing perfor-mance, electronics noise, and gain stability are presented. High energy deposits from radiative cosmic muons and beam splash events allow to check the intrinsic constant term of the energy resolutio…
Search for anomaly-mediated supersymmetry breaking with the ATLAS detector based on a disappearing-track signature in $pp$ collisions at $\sqrt{s}=7$…
2012
In models of anomaly-mediated supersymmetry breaking (AMSB), the lightest chargino is predicted to have a lifetime long enough to be detected in collider experiments. This letter explores AMSB scenarios in pp collisions at s√=7 TeV by attempting to identify decaying charginos which result in tracks that appear to have few associated hits in the outer region of the tracking system. The search was based on data corresponding to an integrated luminosity of 1.02 fb[superscript −1] collected with the ATLAS detector in 2011. The pT spectrum of candidate tracks is found to be consistent with the expectation from Standard Model background processes and constraints on the lifetime and the production…
