safflower as an original crop in iran has high adaptability to different environmental conditions. iran is one of the original areas of safflower as a drought and salinity tolerant crop. therefor, safflower can be a suitable alternative crop for cultivation in marginal areas. the aims of research were studying the late season drought effects on seed and oil yields and its components of fall saf...

We study the Ramond twisted representations of the affine W algebra W(ḡ, f) in the case that f admits a good even grading. We establish the vanishing and the almost irreducibility of the corresponding BRST cohomology. This confirms some of the recent conjectures of Kac and Wakimoto [KW5]. In type A, our results give the characters of all irreducible ordinary Ramond twisted representations of W(...

We study the Ramond twisted representations of the affine W algebra W(ḡ, f) in the case that f is Richardson. We establish the vanishing and the almost irreducibility of the corresponding BRST cohomology. This confirms some of the recent conjectures of Kac and Wakimoto [KW5]. In type A, our results give the characters of all irreducible ordinary Ramond twisted representations of W(sln, f) for a...
