On a Mixed Arithmetic-Mean, Geometric-Mean, Harmonic-Mean Inequality [PDF]

open access: yes, 2023
In 1992, F. Holland conjectured a mixed arithmetic-mean, geometric-mean inequality and it was proved by K. Kedlaya in 1994. In this note, we provide more extended inequality: a mixed arithmetic-mean, geometric-mean, harmonic-mean ...

On the Influence of Geometric Parameters of a Combined Orifice Valve on the Attainable Mean Droplet Diameter during High-Pressure Homogenization

open access: yesEngineering in Life Sciences, 2002
In order to meet the demands of the pharmaceutical and cosmetic industry for decreasing emulsion droplet sizes, new dispersing units are consistently developed. To obtain optimal results, thus the smallest possible droplet diameter and a narrow droplet size distribution at smallest possible energy input, the geometric parameters of a new dispersing ...

Bilateral carotid artery geometry using magnetic resonance angiography: a 10-year longitudinal single center study

open access: yesScientific Reports, 2022
Aging and atherosclerotic progression can lead to geometric changes in the carotid arteries. We conducted a longitudinal study to investigate geometric changes in the bilateral carotid arteries.

Geometrical characteristics of eggs from 3 poultry species

open access: yesPoultry Science, 2021
We studied the correlations between egg geometrical parameters (i.e., egg shape index, sphericity, geometric mean diameter, surface area, and volume) and eggshell qualities, or the organic matrix in eggshell.

Modeling and computation of two phase geometric biomembranes using surface finite elements [PDF]

open access: yes, 2010
Biomembranes consisting of multiple lipids may involve phase separation phenomena leading to coexisting domains of different lipid compositions.

Crop Residue Return Rather Than Organic Manure Increases Soil Aggregate Stability under Corn–Soybean Rotation in Surface Mollisols

open access: yesAgriculture, 2022
Fertilization practices change soil organic carbon content and distribution, which is relevant to crop rotation and soil aggregates. However, how fertilization management under corn–soybean rotation affects soil organic carbon and aggregate stability at ...

Evaluation of a Partector Pro for atmospheric particle number size distribution and number concentration measurements at an urban background site [PDF]

open access: yesAerosol Research
Particle number size distributions, total number concentrations and mean particle sizes have been measured for 70 d at an urban background site in Mülheim-Styrum, Germany, with a handheld Partector Pro of the first generation and a TSI mobility particle ...
