The primary goal of immune monitoring with ELISPOT is to measure the number of T cells, specific for any antigen, accurately and reproducibly between different laboratories. In ELISPOT assays, antigen-specific T cells secrete cytokines, forming spots of different sizes on a membrane with variable background intensities. Due to the subjective nature of judging maximal and minimal spot sizes, dif...
Hydrological models are used to represent the rainfallrunoff and pollutant transport mechanisms within watersheds. Accurate representation of these dynamic and complex natural processes within a watershed is an important step in managing and protecting a watershed Artificial neural network (ANN) models are often used in hydrologic modeling. Typical ANN models are trained to use lumped data. How...
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...
Association of collective attitudes and contraceptive practice in nine sub-Saharan African countries
Abstract. Long-term monitoring at sites with relatively low particulate pollution could provide an opportunity to identify changes in pollutant concentration and potential effects of current air quality policies. In this study, 9-year sampling PM10 (particles aerodynamic diameter below 10 µm) was performed a rural background site France (Observatoire Pérenne de l'Environnement or OPE) from 28 F...
Fertility in sub-Saharan africa (“africa”) stood at 5.1 births per woman in 2005–10 (united nations 2011), more than double the replacement level. this high fertility combined with declining mortality has resulted in rapid population growth—2.5 percent per year—and the un projects the sub-Saharan population to grow from 0.86 billion in 2010 to 1.96 billion in 2050 and 3.36 billion in 2100. Such...
