phosphorus (p) sorption in soils is a key process governing its availability to crops. there has been scanty information available on the p sorption characteristics of calcare-ous soils of western azarbaijan province, iran. in this study, p sorption characteristics and their relationship to soil properties were determined in 36 soil samples belonging to 15 agricultural soil series located in th...

Increasing the current precision of nutrient management will need analytical tools that aid in collecting site specific data. A technology with potential is hyperspectral remote sensing. Modern, portable spectroradiometers permit reflectance data in the spectral region between 350 and 2500 nm to be collected quickly. With the limited sampling, handling, and processing required the technology al...

A confidence region for topologies is a data-dependent set of topologies that, with high probability, can be expected to contain the true topology. Because of the connection between confidence regions and hypothesis tests, implicitly or explicitly, the construction of confidence regions for topologies is a component of many phylogenetic studies. Existing methods for constructing confidence regi...

Computer data acquisition is more and more widely used in today’s undergraduate laboratory courses. To meet this trend, it is necessary to bring computer data acquisition to old laboratory equipment, such as a Tinius Olsen machine. One solution is to go to the equipment’s original manufacturer or other vendors for a retrofitting package with computer data acquisition, that usually costs thousan...
