This modeling study focused on the hydrological and water quality effects of controlled drainage (CD) when operated using a subsurface system in an agricultural field Wielkopolska region. The DRAINMOD hydrologic model was well calibrated validated experimental field. used performance CD free (FD) combinations (108 27, respectively) near-future climate change scenario. objective to understand po...
A resonant Raman study of single-wall carbon nanotubes (SWNT) using several laser lines between 0.94 and 3.05 eV is presented. A detailed lineshape analysis shows that the bands associated with the nanotube radial breathing mode are composed of a sum of individual peaks whose relative intensities depend strongly on the laser energy, in agreement with prior work. On the other hand, the shape of ...
برای تعیین درصد دز عمقی باریکههای فوتونی با انرژیهای مختلف در دزیمتر ژلی- پلیمری PAGAT و وابستگی آن به آهنگ دز با استفاده از تکنیک ام.آر.آی از مواد و ترکیبات شیمیایی با درصدهای وزنی زیر استفاده شده است: 4.5% بیس N-N' متیلن- بیس-آکریلآمید 4.5% آکریلآمید، 5 درصد ژلاتین، 5 میلیمول تتراکیس، 0.01 میلیمول هیدروکینون و 86 درصد آب دو بار تقطیر شده. برای تابشدهی ویالها از فوتونهای Co<su...
East Asian Meiyu simulated by 35 global atmospheric models from the 6th Coupled Model Intercomparison Project (CMIP6)/Atmospheric (AMIP) were systematically evaluated for 1998–2014. The results show that most of CMIP6/AMIP can hardly reproduce observed spatial pattern and interannual variability Meiyu. is relatively better over Southern Korea Japan where 14 out have realistically precipitation,...
Many fish species are shifting spatial distributions in response to climate change, but projecting these shifts and measuring their impact at fine scales challenging. We present a simulation that projects change fishery landings due distribution shifts, by combining regional ocean biogeochemical models (forced three earth system models, ESMs: GFDL-ESM2M, HadGEM2-ES, IPSL-CM5A-MR), correlative f...
The equatorial Pacific is a region with strong negative feedbacks. Yet coupled general circulation models (GCMs) have exhibited a propensity to develop a significant SST bias in that region, suggesting an unrealistic sensitivity in the coupled models to small energy flux errors that inevitably occur in the individual model components. Could this “hypersensitivity” exhibited in a coupled model b...

We use long-term, coincident O3 and temperature measurements at the regionally representative US Environmental Protection Agency Clean Air Status and Trends Network (CASTNet) over the eastern US from 1988 through 2009 to characterize the surface O3 response to year-to-year fluctuations in weather, for the purpose of evaluating global chemistry-climate models. We first produce a monthly climatol...
