to evaluate land suitability of aq-qalla region for rainfed chickpea cropping, boolean logic and analytical hierarchy process (ahp) methods were used in geographic information system (gis). to achieve this, firstly, climatic and agronomical requirements of chickpea,were identified according to scientific resources. then, thematic requirement maps were provided. the studied environmental-compone...
CHEST / 105/3 / MARCH, 1994 / Supplement 127S levels 1.75 U/mi on day 3 was 53 percent (18 of 34) vs 22 percent (11 of 49) in patients with PCP-III <1.75 U/ ml (p = 0.004). A fatality rate of 64 percent (29 of 45) was associated with elevated lavage PCP-III levels obtained 7 days after ARDS onset vs 21 percent (7 of 29) in patients with PCP levels <1.75 U/mi (p<O.OOl). When patients were analyz...
Listeners lateralized a monaural signal presented against a continuous background of perfectly correlated noise (NO) or of uncorrelated noise (NU). Measures of signal detectability were also secured in separate tests. Psychometric functions (percent correct vs signal energy) were determined for each task. For a tonal signal of either low or high frequency, a listener requires only slightly grea...

First-order, second-moment (FOSM) approximations of limit equilibrium slope stability equations can be combined with digital elevation models to perform spatially distributed probabilistic landslide hazard analyses. This is most easily accomplished using the infinite slope idealization, which is the basis of many published reconnaissance-level slope stability assessments. Comparisons of FOSM an...
BACKGROUND Prostate-specific antigen (PSA) assays have historically produced different results. Our aim was to investigate the comparability of assay results of selected commercially available assay methods designed to measure total, free, or complexed PSA (tPSA, fPSA, and cPSA). METHODS We measured tPSA, fPSA, and cPSA in 70 samples and in the WHO PSA 96/670 reference preparation with 6 assa...
In this study, using the frequency ratio (FR) model, an attempt has been made to identify areas with high groundwater potential of the Sira catchment. Effective factors for preparing groundwater potential map including slope aspect, slope percentage, slope length (LS), Elevation, stream power index (SPI), topographic wetness index (TWI), plan curvature, distance to rivers, distance to roads, di...
BACKGROUND AND PURPOSE This study sought to determine the degree of agreement between asymmetries of neuropsychological functioning and nine methods of quantifying asymmetries of regional cerebral blood flow. METHODS The regional cerebral blood flow methods combined three markers of cerebral blood flow asymmetry (percent hemispheric difference, maximum percent probe-pair asymmetry, and number...
Flood is one of the most destructive natural hazards which impose vast costs in order to compensate its effects, especially in areas where there are manifestations of human development (such as cities). Urban development, particularly in the margins of rivers, has increased flood damages in recent decades. The aim of this study was to develop flood hazard maps of Birjand plain based on analyses...
the assumptions considered in developing the saint-venant equations limit their application in many practical situations. the modified boussinesq equation was presented to overcome the limitation imposed by saint-venant equation due to the presence of non-hydrostatic pressure distribution and steep slope. in this paper a computational model was developed for solving the modified and the traditi...
