In association studies searching for genes underlying complex traits, the results are often inconsistent, and population admixture has been recognized qualitatively as one major potential cause. Hardy-Weinberg equilibrium (HWE) is often employed to test for population admixture; however, its power is generally unknown. Through analytical and simulation approaches, we quantify the power of the H...

Admixed populations have been used for inferring migrations, detecting natural selection, and finding disease genes. These applications often use a simple statistical model of admixture rather than a modeling perspective that incorporates a more realistic history of the admixture process. Here, we develop a general model of admixture that mechanistically accounts for complex historical admixtur...

Abstract Increase in the demand of conventional construction materials and need for providing a sustainable growth field has prompted designers developers to opt ‘alternative materials’ feasible use construction. For this objective, industrial waste products agricultural by are very constructive. These wastes such as Rice Husk Ash Sewage Sludge can be replaced instead cement because their pozzo...

The present work presents focuses on the use of different admixtures for development rendering lime-based mortars with improved adhesion and durability, as well reduction cracking. To this aim, combinations an improver (ethylene–vinyl acetate copolymer, EVA), a water repellent agent (sodium oleate), viscosity enhancer (a starch derivative) mineral admixture (pozzolanic addition nanosilica or me...

The paper is aimed at the study of resistance cement pastes containing various secondary materials (fly ash, zeolite, zeoslag, slag and microsilica) in model environment acid rain. Changes characteristics studied due to rain, such as compressive strength composites, water absorption, penetration aggressive ions, pH material its chemical composition were analysed. Model acidic environments repre...

Abstract Climate action around the world has shifted to potential of global warming contribution from design and construction infrastructures, especially those in demand for concrete. Concrete production use have been identified as contributing >5% world’s greenhouse gas (GHG) emissions. The main aim this research work is critically study net-zero sustainability potentials that can lever...

Groundnut is an important cash crop produced in large quantity North-Western Nigeria. The production of ground nut reached its peak Nigeria during the period 1969 to 1980s, when approximately 1.7 million tonnes pods were from area 1.9 hectares. This enormous waste presently not being harnessed productively other than burning, which a major air pollution and indiscriminate dumping that cause env...
