When the depth of stressed soil is rather small, Plate Load Test (PLT) becomes the most efficient test to estimate the soil properties for design purposes. Among these properties, modulus of subgrade reaction is the most important one that usually employed in roads and concrete pavement design. Two methods are available to perform PLT: static and dynamic methods. Static PLT is usually adopted due to its simplicity and time saving to be performs in comparison with cyclic (dynamic) method. The two methods are described in ASTM standard.
In this paper the effect of the test method used in PLT in estimation of some mechanical soil properties was distinguished via a series of both test methods applied in a same site. The comparison of

Show MoreA detailed experimental study was devoted to the anodic oxidation of oxalic acid using manganese dioxide rotating cylinder anode with the objective to evaluate in a systematic way the effect on the oxalic acid oxidation process of several relevant parameters, including the presence of sodium chloride, the current density (J), the rotation speed, the temperature, and the initial concentration of oxalic acid. Thin manganese dioxide film on graphite substrate has been prepared by electrochemical oxidation from MnSO4-H2SO4 electrolyte. The morphology of this electrode was investigated by XRD, SEM, EDS and AFM techniques. The results show that a firm γ-structure of MnO2 film on graphite rod can be obtained successfully.

In order to investigate the phytochemicals presence in the seeds of local plant of Datura stramonium rather than alkaloids. For this purpose two types of Datura stramonium extract were prepared. The first was precipitated by acetone and the other was destructed by ether then precipitated with ammonium sulphate. The first extract yielded 2.5gram/ 5 gram of seeds weight; while, the second extract yielded 1.23 gram/ 5 gram of seed weight. Biochemical tests exhibited that lectin and trace amounts of glycosides were presented in the acetone precipitated extract. Whereas, the ether extract contained lectin, tannin, flavonoids, and trace amounts of alkaloids

Although, loss has become a frightening reality due to the loss of large quantities of food produced by humans for human consumption, so Iraq possesses material capabilities, natural resources, and human beings, it is not self-sufficient, and the reason is the low yield per dounm of wheat, as the productivity rate ranged to 650 kg / dounm for the period 1990-2019. The one of the most important reasons for the decline in productivity is the loss and waste of wheat of post- harvest.
