The aim of this paper is to study the effect organic matter (OM) content on effectiveness soil stabilization process using biopolymer xanthan gum. Five different artificial soils with an in range 1.5 7.7% are subjected unconfined compressive strength (UCS) and oedometer tests evaluate their strength, stiffness compressibility, respectively. These results complemented by analysis SEM images. fro...

Intrinsic motivations can be defined by contrasting them to extrinsic motivations. Extrinsic motivations are directed to drive the learning of behavior directed to satisfy basic needs related to the organisms’ survival and reproduction. Intrinsic motivations, instead, are motivations that serve the evolutionary function of acquiring knowledge (e.g., the capacity to predict) and competence (i.e....

Application of the computer simulation for solving the incompressible flow problems motivates developing efficient and accurate numerical models. The set of Inviscid Incompressible Euler equations can be applied for wide range of engineering applications. For the steady state problems, the equation of continuity can be simultaneously solved with the equations of motion in a coupled manner using...

Crocidolomia binotalis (Cb) (Zeller) is one of the main pests cabbage which difficult for farmers to control in Ijen Crater Indonesia. The demand Indonesia increasing every year, so intensification efforts are continuously being made. Farmers intensively use synthetic pesticides as primary Cb. purpose this study examine several agents that can be used an alternative pesticides. Then, it provide...

New highly sensitive voltammetric DNA-sensors have been developed for the detection of cytostatic drug doxorubicin based on Azure A electropolymerized various carbon nanomaterials, i.e., functionalized multi-walled nanotubes (fMWCNTs) and black (CB). Carbon materials promote electropolymerization dye applied as a matrix DNA molecules saturated with methylene blue (MB) molecules. Interaction int...

The coefficient of isothermal compressibility (oil compressibility) is defined as the fractional change of oil volume per unit change in pressure. Though the oil compressibility so defined frequently appears in the partial-differential equations describing fluid flow in porous media, it is rarely used in this form in practical engineering calculations. Instead, oil compressibility is usually as...
