To examine the relationship of expired capnograms and respiratory system resistance (Rrs) in intubated critically ill patients, we consecutively studied 41 mechanically ventilated patients to (1) analyze the association between expired CO2 slope and auto-positive end-expiratory pressure (auto-PEEP), between Rrs and auto-PEEP, between Rrs and expired CO2 slope, and between Rrs and arterial minus...

Presettlement forest types were mapped as fuzzy sets from point data representing trees contained in General Land Office survey notes (ca.1850) for Chippewa County, Michigan. The resulting representation agreed with a polygon map of the same forest types at 66 percent of the locations (represented as grid cells) in the county. Boundary vagueness was defined in relation to the slope of a linear ...

Erosion is the main threat to sustainable water and soil management in Morocco. Located Souss-Massa watershed, rural municipality of El Faid remains an area where gully erosion a major factor involved degradation flooding. The aim this study predict spatial distribution at scale evaluate predictive capacity three prediction methods (frequency ratio (FR), logistic regression (LR), random forest ...

Echocardiographic measurements of the left ventricular dimensions and wall thicknesses at end diastole and end systole, aortic root and left atrial dimensions, mitral valve E-F slope, left ventricular ejection fraction, percent fractional shortening of the left ventricular internal dimension, estimated left ventricular mass and percentage systolic thickening of the ventricular septum and left v...

An ELISA for measuring thyroglobulin (Tg) in serum was developed with polyclonal antibodies to Tg on the solid phase and two monoclonal antibodies to Tg as the second antibodies. The assay has a detection limit of 1 microgram/L, a within-run imprecision (CV) of <7%, and a between-run CV of < 10%. Parallelism of the assay was shown in dilution studies, in which the percent observed/expected valu...

this study aims at identifying the suitable areas for ecotourism using geographic information system (gis) and analytical hierarchy process (ahp) in experimental and educational kheyroud forest, nowshar, mazandaran province. the evaluation process was conducted based on three groups including ecological, infrastructural, and socio-economic criteria. then, the indicators of each main groups were...

We present new results from a series of ΛCDM simulations of cluster mass halos resolved with high force and mass resolution. These results are compared with recently published simulations from groups using various codes including PKDGRAV, ART, TPM, GRAPE and GADGET. Careful resolution tests show that with 25 million particles within the high resolution region we can resolve to about 0.3% of the...

landfill site selection is an important action in integrated solid waste management process. different criteria should be considered in site selection. therefore using special methods are necessary to evaluate the criteria. the object of the current study was to determine and select suitable sites for solid waste landfill in shiraz city regarding the observation of environmental matters by usin...
