iodine deficiency disorders are among the most important health problems in iran. use of iodized salt is one of the oldest, most convenient and cheapest ways of idd control, although not very easy to implement. factors such as the chemical form of iodine, heat moisture, light and storage affect its stability. in this survey, salt iodine content at production site and the effect of heat, moistur...

Lower Pliocene temperate carbonates exhibit landward-downlapping beds at the southern margin of the Carboneras Basin in south-eastern Spain. This rarely documented stratal geometry resulted from the accumulation of bedded bioclastic carbonate sand and gravel by longshore currents along a spit platform located a few hundred metres from the palaeoshoreline. The top of the spit platform was covere...

Evaluation of the geochemistry and hydrochemical quality of Bam salt dome located in southern Iran, was conducted in this study. Two composite samples from salt units were collected and analysed by XRD and XRF to determine their mineral and elemental compositions. Water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. T...

The identification of salt-dome boundaries in migrated seismic data volumes is important for locating petroleum reservoirs. The presence of noise in the data makes computer-aided saltdome interpretation even more challenging. We have developed noise-robust algorithms that could label boundaries of salt domes effectively and efficiently. Our research is twofold. First, we used a texture-based gr...

The Niger River basin (NRB) is located in the important climatic region of the African Sahel. In this study we use the Lagrangian tridimensional model FLEXPART v9.0 to identify and characterise the moisture sources for the NRB. This method allows the integration of the budget of evaporation minus precipitation over 10-day backward trajectories, thereby identifying the origins of the air masses ...

The atmospheric properties above three sites (Dome C, Dome A and the South Pole) on the Internal Antarctic Plateau are investigated for astronomical applications using the monthly median of the analyses from ECMWF (the European Centre for Medium-Range Weather Forecasts). Radiosoundings extended on a yearly time scale at the South Pole and Dome C are used to quantify the reliability of the ECMWF...

Critical to the origin of life are the ingredients of life, of course, but also the physical and chemical conditions in which prebiotic chemical reactions can take place. These factors place constraints on the types of Hadean environment in which life could have emerged. Many locations, ranging from hydrothermal vents and pumice rafts, through volcanic-hosted splash pools to continental springs...

Salt tectonics at salt-bearing margins is often interpreted as the combination of gravity spreading and gliding, mainly driven by differential sedimentary loading margin tilting, respectively. Nevertheless, in Western Mediterranean Sea, classical salt-tectonic models are incoherent with its morpho-structural setting: Messinian salt was deposited a closed system formed several Ma before depositi...
