considering the current upward drift in farm use all over the world, the russian agro-food market has immense possibilities to create such economic conditions under which the farming sector could develop dynamically. the increase in the grain production is of crucial importance for all agricultural branches. in this respect, the grain sector is russia’s strategically significant economic segmen...

This paper presents the first deterministic selfstabilizing network orientation algorithms. We present three protocols for arbitrary and asynchronous networks. All the protocols set up a chordal sense of direction in the network. The protocols are self-stabilizing, meaning that starting from an arbitrary state, the protocols are guaranteed to reach a state, in which all edge labels (assigned to...

We study the supergravity hybrid inflation model of Ref. [1] in the presence of a modulus field. The η-problem is solved by a shift symmetry for the inflaton, which protects the inflaton mass even in the presence of the modulus field. Inflation is (nearly) unaffected by moduli stabilization, provided the scale of supersymmetry breaking in the post-inflation vacuum is small. Therefore the model ...

We estimate the impacts of various types of government payments to U.S. agriculture on different components of farm household consumption. Using 2003 to 2005 data from the Agricultural Resource Management Survey (ARMS), we show that marginal rates of consumption differ by consumption category and income source, including different types of farm program payments. The results suggest that farm ho...

when the orbital altitude of a small satellite is near-earth, passive stabilization can be considered. the purpose of this paper is to combine the passive gravity gradient and aerodynamic stabilization methods together so that all the three axes stabilizations can be obtained. in this regard, the set of nonlinear equations of motion will be solved numerically with specified initial condition. t...

soil is known as the base material for many structure, on the other hand, some soils cause problems for some structures such as roads. some types of soils absorb moisture and swell then they may shrink when losing water. the changes of moisture in these soil samples cause changes their volume and pressure to layers of the pavement and eventually leads to destruction of roads. therefore, it is n...
