introduction sustainable agriculture can be more objective than fit into the conceptual framework and it is closely associated with rational behavior. the result of such perspective is that sustainable agriculture is an activity based on rationality. the beginning of the formation of stable rationality requires training to create intellectual flexibility for the farmers in order to acquire know...

The notion of the rational closure of a positive knowledge base K of conditional assertions θi |∼ φi (standing for if θi then normally φi) was first introduced by Lehmann in [2] and developed by Lehmann and Magidor in [3]. Following those authors we would also argue that the rational closure is, in a strong sense, the minimal information, or simplest, rational consequence relation satisfying K....

This paper draws a line from the elements of tangle fractions to the tangle model of DNA recombination. In the process, we sketch the classification of rational tangles, unoriented and oriented rational knots and the application of these subjects to DNA recombination.

In this paper, traditional process design rules for deep drawing of box shapes are used to develop constraints within a dynamic programming (DP) approach to generate a set of alternative optimized process plans that minimize the number of drawing stages and heat treatments. The DP approach is capable of scanning a wide range of different alternative values for process parameters which allows fo...

Many real-time systems use runtime structural reconfiguration mechanisms based on dynamic creation and destruction of components. To support such features, UML-RT provides a set of modeling concepts including optional actor references and multiple containment. However, these concepts are not covered in any of the current formal semantics of UML-RT, thus impeding the testing and formal analysis ...

The aim of this paper is to compute the rational character tables of the dicyclic group $T_{4n}$, the groups of order $pq$ and $pqr$. Some general properties of rational character tables are also considered into account.The aim of this paper is to compute the rational character tables of the dicyclic group $T_{4n}$, the groups of order $pq$ and $pqr$.

A finite group $G$ is called rational if all its irreducible complex characters are rational valued. In this paper we discuss about rational groups with Sylow 2-subgroups of nilpotency class at most 2 by imposing the solvability and nonsolvability assumption on $G$ and also via nilpotency and nonnilpotency assumption of $G$.
