Green beans was used as the research material, based on gas chromatography ion mobility spectroscopy (GC-IMS) and Accessories gas chromatography-mass spectrometry (GC-MS), the odor fingerprints of green beans were analyzed under 9 different treatments, including frying, steaming, boiling, quick freezing, precooling, freeze-drying, bleaching and dye
IMPACT OF AIR POLLUTANTS AND METEOROLOGICAL PARAMETERS ON PNEUMONIA IN OLDER ADULTS: A RETROSPECTIVE COHORT STUDY
Background: This study aimed to investigate the relationship between SELENO EXCELL- SELENIUM 200MCG air pollutants, weather parameters, and the characteristics and mortality of pneumonia in the older adult population.Methods: This retrospective, observational, cross-sectional study included a total of 388 patients.Air pollutants and meteorological
Accelerated Motions of a Fish-Like Foil from Impulsive Starts to Terminal States
It is presented through numerical analysis that accelerated motions of a two-dimensional fish-like foil by fluid forces can be modeled from impulsive starts to terminal states.Time histories of drag coefficient and foil speed depend on a frequency and motion of a foil and amplitude of its caudal fin.Three models that take thrust, inertial drag and
Global hydroelastic model for springing and whipping based on a free-surface CFD code (OpenFOAM)
ABSTRACT: The theoretical background and a numerical solution procedure for a time domain hydroelastic code are presented in this paper.The code combines a VOF-based free surface flow solver with a flexible body motion solver where the body linear elastic deformation is described seat back by a modal superposition of dry mode shapes expressed in a
Optimization of FSP Process Parameters on AA5052 Employing the S/N Ratio and ANOVA Method
AA5052 Baskets bead-on-plate processing has been achieved by the friction stir processing (FSP) technique to examine the manipulation of process parameters.It also improved the base metal surfaces to analyze the microstructure.The tool spinning speed, traverse speed, and axial load were preferred to investigate the effect of friction stir bead-on-p
