Effect of UV Radiation and Salt Stress on the Accumulation of Economically Relevant Secondary Metabolites in Bell Pepper Plants

open access: yesAgronomy, 2020
The green biomass of horticultural plants contains valuable secondary metabolites (SM), which can potentially be extracted and sold. When exposed to stress, plants accumulate higher amounts of these SMs, making the extraction and commercialization even ...

Neutralized solar wind ahead of the Earth's magnetopause as contribution to non-thermal exospheric hydrogen [PDF]

open access: yesAnnales Geophysicae, 2018
In a most recent paper by Qin and Waldrop (2016), it had been found that the scale height of hydrogen in the upper exosphere of the Earth, especially during solar minimum conditions, appears to be surprisingly large. This indicates that during minimum

Calibration of discrete element parameters for simulating wheat crushing

open access: yesFood Science &Nutrition, Volume 11, Issue 12, Page 7751-7764, December 2023., 2023
The mechanical properties of wheat grains were measured and analyzed using discrete element software, which provided crucial data for their processing in a mill. The optimal parameters were calculated and incorporated into the EDEM model for computation, which resulted in a relative error of 1.6% between the calculated and observed values, confirming ...

A Robust Channel Head Extraction Method Based on High‐Resolution Topographic Convergence, Suitable for Both Slowly and Fastly Eroding Landscapes

open access: yesJournal of Geophysical Research: Earth Surface, Volume 128, Issue 9, September 2023., 2023
Abstract Channel networks exert a key control on drainage basins shape and dynamics, including the transfer of water and sediments throughout basins, and thus hydrosedimentary hazards. Landscape dissection by channels results from the competition between hillslope processes and channelized erosion processes such as overland flow or debris flows.

Contribution of bedrock structures to the bedrock surface topography and groundwater flow systems within deep glaciofluvial aquifers in Kurikka, Western Finland

open access: yesEarth Surface Processes and Landforms, Volume 48, Issue 10, Page 2039-2056, August 2023., 2023
We address the relationship between the bedrock structure and bedrock surface topography through conducting structural analysis of the bedrock within the main recharge area of the Kurikka aquifer. Based on the presented results, it is evident that the initial bedrock‐digital elevation model (DEM) with smooth elevation transitions from the elevated ...
