The CEA has developed the CERES-MITHRA (C-M) application to model the radionuclide atmospheric dispersion in order to evaluate the consequences on human health of radionuclide releases in the environment. This application is used either for crisis management or to perform assessment calculations for regulatory safety documents relative to nuclear facilities. C-M code is a time consuming complex...

Rice comes second after wheat in Iran`s food consumption economy. However Iran is one of the greatest rice importer countries all over the world because of its rising population and recent growth in GDP. This paper presents an analysis of cointegration test between rice import and it`s economic factors over the period 1990-2011, employing Engle-Granger model. At first, Dickey-Fuller test shows ...

Large, low-density C-type asteroids are abundant in the main belt. The most prominent of these objects is the dwarf planet Ceres, which presents an advanced stage of evolution. Ceres is almost twice as large as Enceladus, and both objects contain more than 50% of water in volume [1]. Although asteroids cannot benefit from tidal heating like outer planet satellites, their proximity to the Sun pr...

In this paper, a practical scheme for assimilation of multi-temporal and multi-polarization ENVISAT ASAR data in rice crop model to map rice yield has been presented. To achieve this, rice distribution information should be obtained first by rice mapping method to retrieve rice fields from ASAR images, and then an assimilation method is applied to use the temporal single-polarized rice backscat...

Hourly GOES-8 imager data (1345UTC-1945 UTC) from July 20-August 31, 1998 were used to study the daytime variation of shortwave direct radiative forcing (SWARF) of smoke aerosols over biomass burning regions in South America (4-16 S, 51-65 W). Vicarious calibration procedures were used to adjust the GOES visible channel reflectance values for the degradation in signal response. Using Mie theory...

Natural coagulants have received much attention for turbidity removal, thanks to their environmental friendliness. The present study investigates potential application of rice starch for removal of turbidity from aqueous solutions. It considers the effects of four main factors, namely settling time (40-140 min), pH (2-8), slow stirring speed (20-60 rpm), and rice starch dosage (0-200 mg/L), eac...

Cut-elimination is the most prominent form of proof transformation in logic. The elimination of cuts in formal proofs corresponds to the removal of intermediate statements (lemmas) in mathematical proofs. Cut-elimination can be applied to mine real mathematical proofs, i.e. for extracting explicit and algorithmic information. The system CERES (cut-elimination by resolution) is based on automate...

In this article, we estimate the vertical price transmission through the Iranian rice marketing chain by usingmonthly data from March 2000 to February, 2009 and error correction model (ECM).The causality testresults indicate that changes in the producer price clearly led changes in wholesale and retail prices. InProducer-Retail and Wholesale-Retail models, price transmission is asymmetric but i...
