the friction stir process (fsp) is a solid state process, which has been used to insert reinforcing particles into the structure of a material to create a composite with improved properties. magnesium is a light structural metal that is increasingly used in the aerospace and automobile industries. in this research, sic nanoparticles were added to az31 alloy using fsp in two overlaps of 100% and...

Magnesium alloy composites play an important role in the biomaterials field. In this study, a novel Mg-Zn-Ca matrix composite was reinforced by adding 1.0 wt.% MgO nanoparticles via high shear casting process. Hereafter, friction stir processing (FSP) used to achieve good dispersion of particles and improve mechanical properties composites. After preparation materials, varied characterization p...

BACKGROUND Dairy cows have a massive demand for glucose at the onset of lactation. A poor adaption to this period leads to an excessive negative energy balance with an increased risk for ketosis and impaired animal health and production. Besides the measurement of ketones, analysing the glucose concentration in blood is reported as helpful instrument for diagnosis and differentiation of ketosis...

Abstract The strength and wear resistance of aluminium alloys must be improved to enhance their usage in lightweight constructions. Thus, this study, graphene nanoplates (GNPs) boron nitride (BN) nanoparticles were reinforced into the Al 5251 alloy by friction stir processing (FSP). aluminum sheets patterned with holes filled mono GNPs, BN a hybrid GNPs. microstructure, wear, mechanical propert...

Isometric bodyweight squats are fundamental exercises in athletic training and rehabilitation. Previously, we measured muscle activity a normal squat posture (NSP) with the center of foot pressure (COP) intentionally shifted forward as far possible (forward-shifted posture: FSP), patterns varied significantly according to COP location. This study focused on stepwise loading strategy. Ten health...

Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...

Patched-1 (Ptch1) has epithelial, stromal, and systemic roles in murine mammary gland organogenesis, yet specific functions remain undefined. Cre-recombinase-mediated Ptch1 ablation in mammary epithelium increased proliferation and branching, but did not phenocopy transgenic expression of activated Smoothened (SmoM2). Epithelium showed no evidence of canonical hedgehog signaling, and hyperproli...
