Assessing sediment connectivity in dendritic and parallel calanchi systems
2019
Abstract Calanchi, a type of Italian badlands created by a combination of water erosion processes and environmental constraints controlling their development, is a striking example of long-term landscape evolution. Sediment connectivity can be defined as the degree to which a system facilitates the fluxes of sediments through itself. The goal of this research is testing the use of simple morphometric variables for assessing sediment connectivity of calanchi landforms distinguishing between dendritic and parallel systems. For detecting the morphological characteristics controlling the sediment connectivity of calanchi basins, literature data (146 calanchi basins) and measurements carried out…
Oxygen Transport in Tumors
1996
Experimental evidence suggests that the hypoxic fraction in solid tumors may influence its growth, may increase its malignant potential, and may reduce its sensitivity towards non-surgical treatment modalities (e.g., standard irradiation, certain anticancer drugs). The role of the tumor O2 status in radio-/chemotherapy and its impact on relevant tumor biological characteristics of tumors are summarized in Table 1.
