The soil organic carbon (SOC) depth profile provides information for many applications, including monitoring climate change, sequestration, reforestation, and land erosion. Models of the SOC support data interpolation, trend analysis, mapping, can be used in larger pedometric models farming. Model errors may due to statistical variability discrete limited sample size available model calibration...

We explore the possibility of extending depth focus an imaging lens with asymmetric quartic phase-mask, while keeping aberration within a relatively low level. This can be intended, for instance, ophthalmic applications, where no further digital processing take place, relying instead on patient’s neural adaptation to their own aberrations. propose computational optimization method derive design...

The objective of this research was to investigate the variation water quality parameters at different depths Gilgel Gibe I reservoir in Oromia Jimma zone during wet seasons. Five stations within were selected, and determined four (surface, 5 m, 10 15 m). Water analyzed on-site using a HACH, HQ40d portable multi-meter, turbidity measured Wag tech meter laboratory standard method. Comparison amon...

Soil erosion is one of the vital factors contributing to the loss of fertility and environmental degradation. Generally accepted diagnostics of eroded soils is based on comparison of the sloping soils profile depth with the watershed soils. In this case, there is a separate problem of slope soils with a naturally shortened profile and eroded soils. Formation of the soil’s natura...

The regulatory functions of soil are getting attention among the scientists and Soil Organic Carbon (SOC) is an important indicator of soil health. The impact of differential use of land on SOC and other edaphic properties were analysed in three important Land use land cover (LULC) system of Tripura, northeast India. Soil cores were divided into four depth profiles (0 10, 10 30, 30 50 and 50 10...

In this work, we used the depth resolution function (DRF) of the secondary ion mass spectrometry (SIMS) to deconvolve the boron depth profile of nanometer-thin embedded diamond layers. Thanks to an isotopic change within a thin layer, where carbon-12 (C) and carbon-13 (C) are substituted, the DRF was evaluated by a self-consistent algorithm. In a second step, this DRF was used to deconvolve the...

This paper addresses the dam-break problem for particle suspensions, that is, the flow of a finite volume of suspension released suddenly down an inclined flume. We were concerned with concentrated suspensions made up of neutrally buoyant non-colloidal particles within a Newtonian fluid. Experiments were conducted over wide ranges of slope, concentration and mass. The major contributions of our...
