Paleosols include soils formed under climatic condition different from the present. Although such soils are widespread in central Iran region, adequate investigations of them are yet to be carried out. Micromorphology is one of the most important tools in plaeoclimatological studies. This investigation was carried out to study microscopic features of two paleosols from Isfahan province to recon...
The anatomy, morphology and trichome distribution on the aerial parts of Lamium truncatum Boiss. were studied in order to understand the usefulness of these characteristics for systematic purposes. L. truncatum is a Mediterranean element which grows on shady hedge banks, glades, Quercus coccifera L. macchie and forest at an altitude of 300-1650 m in the eastern part of the Mediterranean region ...
The peculiar characteristics of dust toxicity are discussed in relation to the processes taking place at the particle-biological medium interface. Because of surface reactivity, toxicity of solids is not merely predictable from chemical composition and molecular structure, as with water soluble compounds. With particles having the same bulk composition, micromorphology (the thermal and mechanic...
