A series of laboratory experiments has been carried out in which parallel-laminated deposits were produced from an upper-regime plane bed. The laminae had thicknesses of a few mm and could be traced continuously over distances up to the length and width of the depositional area (0.3m by 1.5m). Fluctuations in bed elevation were measured both during deposition and at equilibrium; much of the bed...

In this study, Particulate Matter (PM) samples, collected during 2 summer and 2 winter months over a long-term period (1984–2012) at a suburban site in Athens (Greece), were used in order to examine the connection between Sahara dust long range transport events and mass concentrations of the aerosol mineral component, as well as the relative abundance of specific crustal components. As a result...

Grain size is a proxy indicator of airflow intensity and also provides scientific basis for the prevention dust hazards. However, variations in grain characteristics that occur during transport deposition processes are seldom discussed. Here, atmospheric samples were collected before after sand–dust storm analysis. The results showed distributions unimodal transportation but always became bimod...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...

Introduction In the last few years, attentions have been intensively directed toward natural compounds for using in chronic metabolic disorders treatment such as dyslipidemia and diabetes mellitus. There are comprehensive results of experimental and epidemiological investigations that have indicated chemoprotective effects of plant based medicines on chronic diseases. Vegetables and fruits are ...
