The main objective of the work was to define the optimum operating conditions, i.e. temperature range, pressure, C2H6/O2 ratio, reactant mixture density and oxygen admission mode, in order to maximize the ethylene yield of the process.
They are sometimes operated in partial admission mode, depending on the stability of the energy source, such as solar energy or waste thermal energy, which can fluctuate depending on environmental or process condition.
The admission mode in ICU was the same (Emergencies Department: medium old = 32%%, very old = 22 %, home by SMUR: medium old = 2.8 %, very old = 6.5%%, already hospitalized: medium old = 39%%, very old = 34%%, p = 0.34).
Several variables are collected in the registry including: age, gender, time of admission, mode of arrival, vital signs, injury mechanism, severity scores, procedures, length of hospital stay and discharge disposition (Alghnam et al. 2014).
These provide a special admission mode (special track) in parallel to the existing methods of national entrance examination and direct admission.
Key patient data recorded: age, gender, type of admission (medical or surgical), admission mode (direct or transfer), number (1, 2, 3), duration and type of support (respiratory, renal, circulatory) and SAPS II.
The determinants were time of delivery, mother's age, parity, number of previous abortions, gestational age, haemoglobin concentration (Hb) at admission, mode of delivery, perineal tear, sex of the baby, and birthweight.
Available data were: age, length of stay, ICD-10 codes for diagnosis (up to 10 codes), ICD-9-CM codes for procedures, discharge location, admission mode (urgent or not), some hospital related variables.
*From single logistic regression model with all comorbidities, adjusted for length of stay of index hospital admission, mode of admission (elective or not), number of admissions in previous 12 months, number of procedures during index admission, and hemoglobin and sodium concentrations at discharge of index admission.
