| In the north Atlantic subtropical gyre, the oceanic vertical structure of density is characterized by a region of rapid increase with depth. This layer is called the permanent pycnocline because this density feature is observed throughout the year. The pycnocline is the transition layer between light, low-latitude, surface water masses which are ventilated every winter when penetrated locally by the mixed layer and dense, deeper water masses whose properties are set in the high latitudes and circulate equatorward. In-situ data from the Argo array provide temperature/salinity profiles allowing the characterization in space and time of the permanent pycnocline. We thus developed a new method to characterize its depth, thickness and thermohaline... |

| By taking Ningxia Hui Autonomous Region as an example, this paper analyzes the ecological migration pattern in ethnic minority areas. The basic patterns of development for poverty relief in Ningxia are in-situ migration and new area development pattern. The new area development pattern includes three types, namely small town development pattern around urban radiation districts, urban labor migration pattern, and large-scale ecological migration pattern. Finally, successful experience of ecological migration in Ningxia is summarized. First, scientific industrial planning shall be made on the basis of proper selection of ecological migration location in immigrant settlement regions. Second, scientific and comprehensive ecological migration policies should be... |

| A patternator was designed and constructed with the aim of field sprayers pattern testing and consequently application of more accurate weed control, reduce environmental and economic costs associated with weed control. The patternator was tested at six spray height (50, 60, 70, 80, 90 and 100 cm) for each of the three levels of system pressure (1.0, 2.0 and 3.0 bar). All measurements were performed spraying water with a temperature of 20 oC in the laboratory. Environmental conditions are kept constant at a temperature of 48 oC, relative humidity of 51% and wind speed 3 m/s. The Spray Width (cm), Standard Deviation and Coefficient of Variation (CV) of spray distribution patterns obtained from Patternator experiments at various nozzle heights and pressures.... |
