Particle size distribution (size-range 3–900 nm) and PM10 was measured simultaneously at an urban background station in Copenhagen, a near-city background and a rural location during a period in September–November 2002. The study investigates the contribution from urban versus regional sources of particle number and mass concentration. The total particle number (ToN) and NOx are well correlated...

WIMP-nucleon cross sections σ ∼ < 10 −9 pb may be probed by ton-scale experiments with low thresholds and background rates ∼ 20 events per year. An array of cryogenic detectors (" CryoArray ") could perform well enough to reach this goal. Sufficient discrimination and background suppression of photons has already been demonstrated. Reduction of neutron backgrounds may be achieved by siting the ...

a simple mechanistic model was constructed to evaluate potential dry matter of pearl millet. all needed parameters were calculated based on many field and laboratory experiments and actual data obtained from 86 fields of millet located at different regions of khorasan&apos;s provinces. the major simulated processes were crop phenology (as a function of temperature and photoperiod function curve...

The combination of Biotara bio fertilizer and dolomite is known to improve the potential acid sulphate soil fertility. This research has been carried out examine effect as fertilizer, chicken manure, on several chemical properties soybean growth in from May 2018 January 2019 at greenhouse Agricultural Faculty, Universitas Sumatera Utara Medan. using factorial randomized block design with 2 (two...

abstract in order to investigate the effects of nutrient resources and weed management on qualitative and quantitative criteria of cat tyme (teucrium polium), an experiment was conducted as split plot based on a complete randomized block design with 3 replications at the agricultural research station, ferdowsi university of mashhad, iran, during the years 2008 and 2009. treatments included diff...
