Energetic electron precipitation (EEP) into the atmosphere are considered to play an important role in natural forcing of ozone variability and dynamics middle during magnetospheric geomagnetic disturbances. electrons from radiation belt spill out disturbances cause additional ionization rates polar atmosphere. These induced atmospheric lead formation radicals ion-molecular reactions at heights...
The long term archiving of both Landsat imagery and wheat yield mapping datasets sensed by precision agriculture technology has the potential through the development of statistical relationships to predict high resolution estimates of wheat yield over large areas for multiple seasons. Quantifying past yield performance over different growing seasons can inform agricultural management decisions ...
There have been important changes in the United Kingdom’s (UK) fertility and immigration in the past decade, with a large share contributed by migrants from Poland. A detailed understanding of Polish migrant fertility is lacking, however, because the relevant data are not routinely collected. This paper provides new insights into the fertility patterns of Polish migrants in the UK, and compares...
Zooplankton biomass of reservoirs in different trophic conditions in the State of São Paulo, Brazil.
This paper reports on a study involving an estimate of the biomass of rotifers, cladocerans, and cyclopoid and calanoid copepods found in reservoirs in different trophic conditions, comparing and relating numerical density data and pointing out differences between the dry and rainy seasons. In terms of numerical densities, both reservoirs were dominated by rotifers, although cladocerans represe...
