Previous observations suggested that Ceres has active, but possibly sporadic, water outgassing as well as possibly varying spectral characteristics over a timescale of months. We used all available data of Ceres collected in the past three decades from the ground and the Hubble Space Telescope, as well as the newly acquired images by the Dawn Framing Camera, to search for spectral and albedo va...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
The masses of the three largest asteroids: (1) Ceres, (2) Pallas and (4) Vesta were determined from gravitational perturbations exerted on respectively 25, 2, and 26 selected asteroids. These masses were calculated by means of the leastsquares method as weighted means of the values obtained separately from the perturbations on single asteroids. Special attention was paid to the selection of the...
We define a generalization CERES of the first-order cut-elimination method CERES to higher-order logic. At the core of CERES lies the computation of an (unsatisfiable) set of sequents CS(π) (the characteristic sequent set) from a proof π of a sequent S. A refutation of CS(π) in a higher-order resolution calculus can be used to transform cut-free parts of π (the proof projections) into a cut-fre...
[1] Using spatially and temporally collocated data sets from the Clouds and Earth’s Radiant Energy System (CERES) and Moderate-Resolution Imaging Spectroradiometer (MODIS) instruments on the Terra satellite, a new strategy is presented for studying the Shortwave Aerosol Radiative Forcing (SWARF) over the global oceans. Using collocated data, for September 2000, the global averaged optical thick...
Introduction: Interpretation of data acquired at Ceres by the Dawn spacecraft demands a model for the evolution of Ceres’ structure and composition to date. In a recent paper [1], we presented such a model, consistent with pre-Dawn observations and preliminary data returned by Dawn. Here, we describe this model, compare its physico-chemical outcomes to reported observations, and outline possibl...
[1] Spectral albedo and bidirectional reflectance of snow were measured at Dome C on the East Antarctic Plateau for wavelengths of 350–2400 nm and solar zenith angles of 52°–87°. A parameterization of bidirectional reflectance, based on those measurements, is used as the lower boundary condition in the atmospheric radiation model SBDART to calculate radiance and flux at the top of the atmospher...
Response of Crop Water Requirement and Yield of Irrigated Rice to Elevated Temperature in Bangladesh
In the changing climatic condition, temperature is most vulnerable parameter and projecting a trend of increase in future. Crop growth development process depend largely on air temperature. This study aims to determine role increasing yield, crop water requirement (CWR), other agronomic parameters irrigated rice. Ceres-rice model associated Decision Support System for Agrotechnology Transfer (D...
