evaluation of salinity tolerance of forage sorghum varieties with stress tolerance and susceptibility indices

the objective of this study was evaluation of salt tolerance of elite forage sorghum lines in laboratory and field conditions. salinity treatments were 5, 10, 15, 20, 25, 30 decisimens per meter in laboratory and distilled water as control. lines were kfs1, kfs2, kfs3, kfs4, mfs1, mfs2 and lfs56. the lines also cultivated in saline and non saline field conditions during 2004-2005. electrical co...

compactifications and representations of transformation semigroups

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

investigating the relationship between ambiguity tolerance and willingness to translate of iranian prospective english translators: an sem revalidation study

cognitive studies of translation process have recently been awarded a great deal of attention. there exists a psychological angle to almost all translation activities. the present study, thus, deals with analysing the relationships between iranian prospective translators tolerance for ambiguity (ta) and their willingness to translate (wtt). the research was conducted as a mixed methods study, d...

Varieties of Commutative Semigroups

In this paper, we describe all equational theories of commutative semigroups in terms of certain well-quasi-orderings on the set of finite sequences of nonnegative integers. This description yields many old and new results on varieties of commutative semigroups. In particular, we obtain also a description of the lattice of varieties of commutative semigroups, and we give an explicit uniform sol...
