Classical treatment of cell attachment by models of filtration or coulombic attraction assumes that attachment of cells to mineral surfaces would be controlled by factors such as response to predation, collision efficiency, or coulombic attraction between the charged groups at the mineral and cell surfaces. In the study reported here, the passive model of attachment was investigated using a nat...
Oxygen three-isotope ratios of three anhydrous chondritic interplanetary dust particles (IDPs) were analyzed using an ion microprobe with a 2 lm small beam. The three anhydrous IDPs show DO values ranging from )5& to +1&, which overlap with those of ferromagnesian silicate particles from comet Wild 2 and anhydrous porous IDPs. For the first time, internal oxygen isotope heterogeneity was resolv...
The study area is located in northwest of Isfahan, 25 km northwest of Daran. Buin-Miandasht intrusive rocks consist of granite and granodiorite. Based on geochemical diagrams, these granitoids are I -type calc-alkaline and evolved in volcanic arc environments. The Buin-Miandasht intruded into the metamorphic basement (Paleozoic?) and a small skarn and hornfels occurred along its contact. Based ...
