Effect of Moisture Content and Normal Impact Velocity on the Coefficient of Restitution of ‘Memory’ Wheat Grains
Published 2025-05-01“…Force–time curves were examined to evaluate restitution velocity, the coefficient of restitution (CoR) and the effect of moisture on elastic–plastic deformation. CoR decreased non-linearly as impact velocity rose from 1.0 to 5.0 m·s<sup>−1</sup>, and moisture content increased from 7% to 16%, falling from ≈ 0.60 to 0.40–0.50. …”

Polarimetric Properties of Event Horizon Telescope Targets from ALMA
Published 2021-01-01“…We determine the polarization and Faraday properties of all VLBI targets, including Sgr A*, M87, and a dozen radio-loud active galactic nuclei (AGNs), in the two bands at several epochs in a time window of 10 days. We detect high linear polarization fractions (2%–15%) and large rotation measures (RM > 10 ^3.3 –10 ^5.5 rad m ^−2 ), confirming the trends of previous AGN studies at millimeter wavelengths. …”

A Validated RP-HPLC Stability Method for the Estimation of Chlorthalidone and Its Process-Related Impurities in an API and Tablet Formulation
Published 2020-01-01“…Validation studies for the in-house process impurities were performed for specificity, limit of detection (LOD), limit of quantitation (LOQ), linearity, precision, accuracy, and robustness. Thus, an improved RP-HPLC method capable of good separation of all known and unknown impurities with acceptable resolution and tailing factor was developed.…”

The cultivation possibility of tall oat grass and red clover mixture on acidic soil in order to develop a sustainable management system
Published 2025-03-01“…And if it was expected that the proportion of clover and the intensity of nitrogen fixation generally increase with the application of soil liming, this study showed that in some cases the crop responded differently and non-linearly to the application of lime. By growing red clover in a mixture with tall oat grass and applying soil liming on acidic soils, satisfactory yields can be achieved while recovering the soil from intensive exploitation, which can be good practice for developing a sustainable management system in agriculture. …”

Molecular diversity of dissolved organic matter reflects macroecological patterns in river networks
Published 2025-07-01“…Crucially, the scaling parameters (B, baseline chemodiversity; Z, sensitivity) are linearly interrelated. This B–Z relationship is most robust for potentially bio-labile carbohydrates (coefficient of determination R2 ≈ 0.85), diminishing for recalcitrant, plant-derived molecules (such as lignin), and indicates (potential) biolability-dependent coupling between baseline diversity and environmental responsiveness. …”
