We suggest that insufficiently
bombarded films develop a Maxwell-Wagner type polarization along columnar voids. The void structure and the associated dielectric response vary with distance from the sputtering source due to variations in ion density and angle from the sputtering source. A similar dielectric response is observed in depositions on Selonsertib mouse on-axis substrates as a function of angle from the central sputter gun axis. Our results suggest that ion bombardment is necessary for good quality sputtered dielectric films but that a controlled Ar(+) flux is essentially equivalent to the uncontrolled O(2)(-)/O(2-) flux of on-axis reactive sputtering.

“Our objective was to translate and validate a Portuguese version of the Urinary Incontinence-Specific Quality-of-Life Instrument (I-QOL), a questionnaire that is widely used in clinical trials.
Fifty patients completed the same questionnaire twice at a 2-week interval. During the first visit, we conducted a face-to-face interview and collected demographic data. The King’s Health Questionnaire was completed during the same visit for comparisons.
The results showed that the Portuguese version of the Selleck MK-8931 I-QOL has very good psychometrics
properties. Reliability was assessed by Cronbach’s alpha (0.93), reproducibility was calculated through the intraclass correlation coefficient (0.88), construct validity was determined by comparing the I-QOL scores and King’s Health scores, and discriminant validity was calculated by comparing the total I-QOL scores with measures of gravity.
We conclude that the Portuguese version of the I-QOL is a very good tool for the evaluation quality-of-life in women with urinary incontinence in Portuguese-speaking countries.”
“Background The pediatric difficult airway can be unexpected, leading to significant
morbidity and mortality. Standardized emergency airway equipment should be available on a regularly checked difficult airway trolley (DAT). We conducted a survey to investigate pediatric anesthetists’ knowledge, experience, and confidence with the DAT.
Methods Members of the Association of Paediatric Anaesthetists of Great Britain and Ireland (APAGBI), European Society for Paediatric Anaesthesiology (ESPA) and Natural Product Library their national societies, Canadian Pediatric Anesthesia Society (CPAS), and Society for Paediatric Anaesthesia in New Zealand and Australia (SPANZA) were invited to complete a survey between January and April 2011.
Results Six hundred and ninety-three anesthetists replied to the questionnaire. Six hundred and thirty-three (92%) stated they have a DAT in their theater suite, with 587 (98%) knowing its location. Three hundred and eight-seven (56%) anesthetists received formal DAT training. The lowest training levels were observed in Australia and the UK; 42% and 59%, respectively.
