IL SONNO NEL LAVORO A TURNI: CONFRONTO TRA TURNI "3X8" E "2X12".

Abstract: Sleep in night shift work: comparison between \u201c3x8\u201d and \u201c2x12\u201d fast rotating shift schedules The study was aimed at assessing the impact of 3 types of fast rotating shift systems on stress, fatigue, sleep and hormonal secretion. Subjects: Among 294 hospital nurses, examined in a survey on work related stress, three groups of 10 nurses were randomly selected for a comparison of three shift work schedules: a) 10 working in the resuscitation unit on a \u201c3x8\u201d shift system in a 5-day cycle with a \u201cquick return\u201d: Afternoon (14-21); Morning (07-14) and Night (21-07); End of Night shift; 2 Rest days; b) 10 working in the surgical ward on a \u201c3x8\u201d shift system in a 6-day cycle with a \u201cquick return\u201d: Afternoon; Morning; Morning and Night; End of Night shift; 2 Rest days; c) 10 working in the delivery room on a \u201c2x12\u201d shift system in a 5-day cycle: Daywork (07-19); Nightwork (19-07); End of Night shift; 2 Rest days. Seventeen nurses were women and 13 men, aged between 23 and 46 years (mean 34.3) and with work seniority between 1.4 and 28 years (mean 11.4). All were in good health and not taking any medication. Methods: They have been submitted to a semi-structured interview including the Standard Shiftwork Index, the Job Demand-Control and the Effort Reward Imbalance questionnaires, the Epworth sleep scale. During the whole shift cycle, the nurses recorded their activity and rest periods by actigraphy and personal diaries, assessing sleepiness by the Karolinska Sleepiness Scale and quality of sleep by a 10-point visual scale. They also took saliva samples at 0700 and 2300 of each working and rest day for dosage of cortisol, cortisone and melatonin. Results: The nurses reported more sleep troubles in both \u201c3x8\u201d than in \u201c2x12\u201d shift schedule. According to actigraphy, in both \u201c3x8\u201d shift schedules the duration of night sleep between afternoon and morning shifts is reduced by 35% as compared to rest days, and sleep between morning and night shifts in the same day lasts less than 3 hours on average, showing a significantly higher fragmentation in both occasions. Also subjective sleepiness is significantly higher before night shift in both \u201c3x8\u201d shift schedules than in the \u201c2x12\u201d one. In the surgery ward, where they can nap/sleep up to 3 hours during the night shift, the nurses have a 40% shorter sleep in the morning after. In the \u201c2x12\u201d shift schedule the night sleep duration between Day and Night shift is the same as in the rest days. As far as hormonal secretion, cortisol and cortisone did not change significantly their normal circadian phase in all the three shift schedules, whereas melatonin showed a more irregular pattern

Orari di lavoro e sonno nel personale infermieristico impiegato in sistemi di turnazione rapida "23x8" e "2x12"

Obiettivo dello studio \ue8 di verificare, in un campione di 200 infermieri turnisti, l\u2019impatto sul sonno della diversa tipologia di lavoro (\u201cemergenza/urgenza\u201d vs. \u201cdegenza\u201d) nell\u2019ambito dello stesso schema di turno, e di due diversi schemi di turnazione a rotazione rapida (\u201c2x12\u201d e \u201c3x8\u201d), nell\u2019ambito della stessa area di lavoro (\u201cemergenza/urgenza\u201d). Il turno notturno e quello del mattino risultano interferire maggiormente con il sonno, sia in relazione ai due tipi di turno che alle due aree operative considerate. Emerge l\u2019importanza di considerare, nella strutturazione dello schema dei turni, le modalit\ue0 di rotazione tra i turni e il carico di lavoro in relazione alla durata del turno stesso

ATLAS Pixel Opto-Electronics

We have developed two radiation-hard ASICs for optical data transmission in the ATLAS pixel detector at the LHC at CERN: a driver chip for a Vertical Cavity Surface Emitting Laser (VCSEL) diode for 80 Mbit/s data transmission from the detector, and a Bi-Phase Mark decoder chip to recover the control data and 40 MHz clock received optically by a PIN diode. We have successfully implemented both ASICs in 0.25 micron CMOS technology using enclosed layout transistors and guard rings for increased radiation hardness. We present results of the performance of these chips, including irradiation with 24 GeV protons up to 61 Mrad (2.3 x 10e15 p/cm^2).Comment: 17 pages, 23 figures, submitted to NIM Added references.

Transverse momentum spectra of charged particles in proton-proton collisions at s=900\sqrt{s} = 900 GeV with ALICE at the LHC

The inclusive charged particle transverse momentum distribution is measured in proton-proton collisions at $\sqrt{s} = 900$ GeV at the LHC using the ALICE detector. The measurement is performed in the central pseudorapidity region $(|\eta|<0.8)$ over the transverse momentum range $0.15<p_{\rm T}<10$ GeV/$c$. The correlation between transverse momentum and particle multiplicity is also studied. Results are presented for inelastic (INEL) and non-single-diffractive (NSD) events. The average transverse momentum for $|\eta|<0.8$ is $\left<p_{\rm T}\right>_{\rm INEL}=0.483\pm0.001$ (stat.) $\pm0.007$ (syst.) GeV/$c$ and \left_{\rm NSD}=0.489\pm0.001 (stat.) $\pm0.007$ (syst.) GeV/$c$, respectively. The data exhibit a slightly larger $\left<p_{\rm T}\right>$ than measurements in wider pseudorapidity intervals. The results are compared to simulations with the Monte Carlo event generators PYTHIA and PHOJET.Comment: 20 pages, 8 figures, 2 tables, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/390
