Friction Stir Processing (FSP) is a solid-state method that widely used in titanium and its alloys to enhance their strength. The FSP technique produces low-defect-density materials with improved mechanical properties, making it potentially valuable for orthopedic dental applications. It primarily low-melting-point such as but can also be applied high-melting-point metals steel, nickel, alloys....
OBJECTIVE Food-insecure populations employ multiple strategies to ensure adequate household food supplies. These strategies may increase the risk of overweight and obesity. However, existing literature reports conflicting associations between these strategies and BMI. The objective of the present study was to examine whether food insecurity and strategies for managing food insecurity are associ...
The chemical master equation (CME) is frequently used in systems biology to quantify the effects of stochastic fluctuations that arise due to biomolecular species with low copy numbers. The CME is a system of ordinary differential equations that describes the evolution of probability density for each population vector in the state-space of the stochastic reaction dynamics. For many examples of ...
Iterated local search (ILS) is a general and powerful metaheuristic which provides an easily implementable way of improving the performance of local search algorithms. In this article we consider the application of ILS to the permutation flow shop problem (FSP), a strongly studied problem in machine scheduling. We experimentally investigate the effect of specific implementation choices in our I...
La0.6Ca0.2Fe0.8Cu0.2O3, undoped (LF) and Ca, Cu-doped (LCFC), powders, obtained by different industrial procedures, are compared to evaluate reproducibility scale-up in synthetic approaches: flame spray pyrolysis (FSP) coprecipitation (COP). Also the effects of varying composition (doping) FSP process variability considered as comparative studies on morphological, crystallographic, redox compos...
In the present study, the effect of material and process parameters on the morphological and hardness properties of friction stir process (FSP) acrylonitrile butadiene styrene (ABS) were investigated. For this purpose, firstly ABS polymeric sheets were injection molded. Then a slot with predetermined depth and width was created on sheets using a horizontal milling machine. Nano type (nanoclay, ...
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...
