Rill erosion is the first step in soil erosion process in the hillslopes, particularly in arid and semiarid regions. This study was conducted to investigate the role of rainfall intensity and raindrop impact on the physical properties of soils and particle detachment capacity (Dc) in a marl soil. Marl soil samples were filled into the flumes with 4 m long and 0.9 m wide and exposed to simulated...

This paper uses the results of river suspended sediment flux (SSF) analysis to propose a new hydrological method for quantitatively estimating the river bed and drainage basin (sheet erosion, rill and gully erosion) components of total erosion intensity in river basins. The suggested method is based on the establishment of the functional power connection between mean monthly water discharges (W...

This study was conducted to investigate the effect of slope gradient and soil physical properties (grain size distribution, bulk density, aggregate stability and permeability) on water erosion in the furrows of rainfed farms under fallow conditions. The furrows with 6 m length were installed in five rainfed farms with 6.1, 10.6, 14.8, 20.7 and 27.1% slope steepness at three replications. Resul...

The leukocyte migration test (LMT) reactivity of breast cancer patients to Rill murine mammary tumor virus (MuMTV) gp55 was studied and compared with simulta neous reactivity to the following: (a) RIM gp55 prepared in another laboratory; (b) gp68, gp34, and p28 of Rill MuMTV; (c) gpSO of A-strain MuMTV; (d) gp70 and gp45 of Rauscher leukemia virus; and (e) autologous and homol ogous lymphoretic...

Campania Region of Southern Italy has a complex environmental situation, due to geogenic and anthropogenic soil pollution. Some of the pollutants such as copper are mobilized in the organic matter. It has been shown that wetlands provide physical as well as biogeochemical barriers against pollutants. Therefore, the objective of this study was to introduce and test an innovative approach able to...

Pemphigus vulgaris (PV) is a potentially fatal autoimmune mucocutaneous blistering disease. Although PV occurs predominantly in adulthood, in the 3rd to 5th decades of life, there have rarely been reports of childhood cases which are often misdiagnosed. It presents as oral blisters that rupture rapidly and progress to painful erosions. Most patients develop cutaneous flaccid blisters that ruptu...
