During the Medieval Climate Anomaly (MCA), Western North America experienced episodes of intense aridity that persisted for multiple decades or longer. These megadroughts are well documented in many proxy records, but the causal mechanisms are poorly understood. General circulation models (GCMs) simulate megadroughts, but do not reproduce the temporal clustering of events during the MCA, sugges...
Many features of the general circulation of the atmosphere shift upward in response to warming in simulations of climate change with both general circulation models (GCMs) and cloud-system-resolving models. The importance of the upward shift is well known, but its physical basis and the extent to which it occurs coherently across variables are not well understood. A transformation is derived he...
The main source of information on future climate conditions are global circulation models (GCMs). While the various GCMs agree on an increase of surface temperature, the predictions for precipitation exhibit high spread among the models, especially in shorter-than-daily temporal resolution. This paper presents a method to predict regional distributions of the hourly rainfall depth based on dail...
A rigorous evaluation of future hydro-climatic changes is necessary for developing climate adaptation strategies a catchment. The integration projections from general circulation models (GCMs) in the simulations hydrologic model, such as Soil and Water Assessment Tool (SWAT), widely considered one most dependable approaches to assess impacts alteration on hydrology. main objective this study wa...
background & aim:zea mays leaf used traditionally in ibibio ethno medicine in southern nigeria to treat malaria and other inflammatory diseases. these anti-inflammatory and analgesic properties were evaluated against experimentally induced inflammation and pains using standard models. experimental: the effects of ethanol leaf extract of zea mays (170 -510 mg/kg) on experimentally induced inflam...
Radiation parameterizations in GCMs are more accurate than their predecessorsErrors in estimates of 4 ×CO2 forcing are large, especially for solar radiationErrors depend on atmospheric state, so global mean error is unknown.
Bile acid diarrhoea (BAD) is a common disease that requires expensive imaging to diagnose. We have tested the efficacy of a new method to identify BAD, based on the detection of differences in volatile organic compounds (VOC) in urine headspace of BAD vs. ulcerative colitis and healthy controls. A total of 110 patients were recruited; 23 with BAD, 42 with ulcerative colitis (UC) and 45 controls...
The purpose of this study was to evaluate the effect of copper and silver in the plants on the mining area and the ingredients of essential oils. Plants collected from the same family, but they were collected randomly from various regions. The concentration of heavy metal in plant samples collected from Veshnave, Qom, Iran have been determined by Flame Atomic Absorption Spectrometry (FAAS). The...
