A laboratory experiment was conducted to determine the effectiveness of ground penetrating radar in identifying mass graves and delineating their boundaries in sandy soil. A GSSI SIR-3000 GPR system with a 1.5 GHz antenna was used for the experiment. Eight GPR profiles were run over a 0.16m-deep wooden sandbox that contained buried bones to simulate the mass grave. All GPR profiles were processed using zero time, background removal, and filters to produce clearer, more accurate, and interpretable GPR data. This geophysical technique showed its assistance and effectiveness in locating the mass grave and tracking its delineation within

Show MoreThe approximate solution of a coupled nonlinear parabolic system with variable coefficients (CNPSVC) is found by using the mixing Galerkin finite element method (GFEM) in the variable of space with implicit finite difference method (IFDM) in the variable of time, for this reason, the method will be denoted by MGIM. In this method and at any step of time the CNPSVC is transformed into couple Galerkin nonlinear algebraic system (CGNAS), which is solved by applying the predictor and the corrector techniques (PCT), these techniques transform the CGNAS into a coupled Galerkin linear algebraic system (CGLAS). Then the Cholesky decomposition (ChDe) is used to solve it. The existence and uniqueness of the solution are proven. The stability and

We define a proper sub-module N of an R-module M to be a weakly 2-quasi-prime sub-module if whenever 0≠r_1 r_2 m∈N, r_1 r_2∈R, m∈M, then either 〖r_1〗^2 m∈N or ∈〖r_2〗^2 m∈N. This concept is an expansion of the idea of a 2-quasi-prime sub-module, where a proper sub-module N of an R-module M is said to be a 2-quasi-prime sub-module if for all a,b∈R, x∈M and abx∈N then either a^2 x∈N or〖 b〗^2 x∈N. Various properties of weakly 2-quasi-prime sub-modules are considered.
Evolutionary algorithms (EAs) provide a framework for dealing with a variety of large-scale multi-objective problems (MOPs) in the field of evolutionary algorithms, when applied to different problem types.

Furthermore, a comprehensive case analysis is presented, demonstrating the practical application of this methodology to the reaction-diffusion system under consideration.
Fusarium oxysporum f. sp. lycopersici is the causal agent of tomato wilt disease. The ability to infect particular plant species depends on specific genes that distinguish virulent fungi from their closely related nonvirulent relatives. These genes encode host-determining "virulence factors," including small, secreted proteins and enzymes involved in the synthesis of toxins. This research aims to study the impact of Trichoderma harazanium extract on the expression of frp1, snf1, and clc1 genes expression on five severely pathogenic isolates of Fusarium oxysporum f.sp. lycopersci for the first time in Iraq.

Show MoreThe environmental difficulties faced by Iraqi society, particularly in the countryside, worsen over time due to a lack of interest in environmental duties caused by a lack of awareness of the environmental risk. At a time when oil companies sought Iraqi government approval to invest in and develop Iraqi oil fields, particularly in the south of Iraq, heavy metals emerged as one of the most visible pollutants associated with the oil industry as by-products of oil extraction operations. Therefore, the environment is exposed to gradual demolitions that directly affect biodiversity and deteriorate water quality in the region. Consequently, it became necessary to find environmentally friendly treatment methods from the elements of the environm

For simplification, the governing equations, infinite wavelength and small Reynolds numbers have been used to study the Newtonian fluid in a porous canal. Heat transport, elasticity, rotation, and slip conditions are taken into account. The Brinkman number, Hartman number, and other parameters are evaluated to observe their effects on the stream function, temperature, velocity, and coefficient of heat transfer. The results indicate that when these parameters are varied, more trapped boluses develop. Figures and graphs discuss and illustrate the impact of various values on these factors. Th

The utilization of artificial intelligence models to predict variations in LST is highly beneficial for assessing and forecasting the dynamic climatic changes occurring worldwide. However, the prediction of LST is a difficult task because slight errors in its short-term forecasts can accumulate to become significant errors over longer periods of time. In this paper, a hybrid model that utilizes a bi-directional long short-term memory (BiLSTM) framework is presented for improving the accuracy of long-term LST prediction. The goal is to forecast the future patterns of LST and
