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

Pemodelan Garis Pantai Menggunakan Metode Interpolasi Stacked Curve Spline Tension
Wilayah pesisir merupakan lingkungan dinamis yang dipengaruhi oleh interaksi atmosfer, daratan dan lautan. Demikian pula, posisi garis pantai juga selalu berubah karena komponen alami dan ulah manusia seperti erosi, gelombang, pasang harian, badai, dan ...

Calibration of discrete element parameters for simulating wheat crushing
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 ...

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.

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 ...
