BACKGROUND The O(2) Flow Regulator (Dima, Bologna, Italy) is a new automated oxygen regulator that titrates the oxygen flow based on a pulse-oximetry signal to maintain a target S(pO(2)). We tested the device's safety and efficacy. METHODS We enrolled 18 subjects with chronic lung disease, exercise-induced desaturation, and on long-term oxygen therapy, in a randomized crossover study with 2 c...

OBJECTIVES To quantify the time spent by family physicians (FP) on tasks other than direct patient contact, to evaluate job satisfaction, to analyse the association between time spent on tasks and physician characteristics, the association between the number of tasks performed and physician characteristics and the association between time spent on tasks and job satisfaction. DESIGN Cross-sect...

bioleaching of spent refinery processing catalysts using adapted indigenous strains ofacidithiobacillus ferrooxidans to recover ni and mo, and the separation of ni from bioleaching liquor usingiron magnetic nanoparticles were optimized in this study. bioleaching optimization was performed usingcentral composite design (ccd) method to optimize temperature (32 to 38oc), initial ph (1.5 to 2), par...

Cancer case management provides consecutive care during the entire process through diagnosis to treatment and follow-up. We established an integrative information system with integration of the health information system. This integrative information system shortened the time spent on case screening, follow-up data management, and monthly data summarization of case managers. It also promoted the...

Editor’s key points † New anaesthetic machines can automatically control the concentrations of volatile agents and fresh gas flow. † This study compared the ETControlTM with manual adjustment of fresh gas flow by the anaesthetist in clinical practice. † Time spent at low gas flows was significantly greater and volatile agent usage and costs were lower when using the automated system. † Further ...

this paper investigates the relationship between earnings management and quality of earnings for the bankrupt and non-bankrupt firms listed in the tehran stock exchange from 2007 to 2012.the earnings quality  is measured by four separate accounting-based earnings attributes: accruals quality, earnings persistence, earnings predictability; earnings and is also examined by testing the relationshi...

abstract accurate prediction of river flow is one of the most important factors in surface water recourses management especially during floods and drought periods. in fact deriving a proper method for flow forecasting is an important challenge in water resources management and engineering. although, during recent decades, some black box models based on artificial neural networks (ann), have bee...

abstract the aim of this study was to evaluate the status of information on forest and data transfer and to identify the gaps in information and data flow in forestry sector in iran. the study evaluated the data and information flow in three levels (control offices level, provincial offices level and organizational offices level) using the document analysis and questioning (interviews and ques...
