This research investigate clayey, lateritic and sandy soils have been selected from agricultural lands in the South-Eastern Nigeria, for their phosphate sorption characteristics using column experiments, in order ascertain the movement of phosphate in the soils. The soil samples were equilibrated in 25ml of 0.01M CaCl2  containing different concentrations of P as KH2PO4 to produce initial conc...

to examine how water retention characteristics in a landfill environment change as a result ofsolid waste settlement and to derive the evolution of pore size distribution, a lab scale long column experiment was carried out at two different time periods while keeping all the other characteristics constant. two columns, column 1 and column 2, were used in the study. the log normal distribution mo...

buckling instability is the most important factor at columns failune. icauses large deflection and mostly is analysed by first yield criterion. due fo some difficulties in application of the criterion, soecially in inelastic columns, a new method, namely geometric criterion is introduced in this paper to improve the buckling analysis of real columns. in this research project a number box- secti...

This paper presents the results of an experiment measuring the difference of reading speed and preference when reading on paper or screen. Extending previous experiments on the topic of reading speed measurements, which usually concentrate in specific age groups, in this experiment, forty two participants from across the adult life span took part in reading on computer screen or on paper. Resul...
