the probable maximum precipitation (pmp) is the greatest depth of precipitation for a given duration that is physically possible over a given size storm area at a particular geographical location at a certain time of the year. in this study a physically based method was compared with a statistical procedure to calculate pmp in the southwest arid regions of iran. in order to estimate pmp using a...

Determining Depth-Area-Duration (DAD) curves in drainage basins is one of the applied researches in hydrology. DAD curves exhibit the depth and the area covered by the rainfall with a particular duration. DAD analysis is widely used in characterization of precipitation extremes for specification of so-called design storms. In this study the DAD curves for the Kurdistan province were prepared an...

OBJECTIVE To determine the data sources and 'look back' intervals to define comorbidities. DATA SOURCES Hospital discharge abstracts database (DAD), physician claims, population registry and death registry from April 1, 1994 to March 31, 2010 in Alberta, Canada. STUDY DESIGN Newly-diagnosed hypertension cases from 1997 to 2008 fiscal years were identified and followed up to 12 years. We def...

a knowledge of rainfall distribution over a finite area is needed for small bydraulic structures design. hydrologists have always been concerned about depth- area- duration (dad) for a specific storm in a watershed. an intense storm occurred on june 6, 1992 which claimed some lives in parts of mashhad, khorasan province, iran. data of rainfall depth at 29 raingauge stations around the city and ...

BACKGROUND Although diffuse alveolar damage (DAD) is considered the typical histological pattern of acute respiratory distress syndrome (ARDS), only half of patients exhibit this morphological hallmark. Patients with DAD may have higher mortality than those without DAD. Therefore, we aimed to identify the factors associated with DAD in patients with ARDS. METHODS We analyzed autopsy samples o...

BACKGROUND Diffuse alveolar damage (DAD) is a typical pathological finding of open lung biopsies in patients with acute respiratory distress syndrome (ARDS). Patients with ARDS and DAD have been reported to have a poorer prognosis than those without DAD. The aim of this study was to investigate the survival predictors in patients with ARDS and DAD. METHODS We retrospectively reviewed all ARDS...

Activation of cardiac sympathetic nerves is recognized as a triggering factor for cardiac arrhythmias. However, the mechanisms involved have only been speculated. Because evidence from studies in vitro has established a relation between catecholamines, delayed afterdepolarizations (DAD), and triggered rhythms, it seemed possible that in vivo adrenergic activation also might lead to the developm...

Patients with rheumatoid arthritis (RA) often have pulmonary involvement, and interstitial lung disease (ILD) is the primary manifestation, in which diffuse alveolar damage (DAD) is a rare histopathologic pattern. Leflunomide (LEF) is a frequently prescribed disease-modifying antirheumatic drug for treating RA. LEF-related ILD in the form of DAD has been reported in patients with RA, with the d...
