the effects of sucrose and some regulators on freezing tolerance in chickpea studied. four weeks in vitro explants were cultured in three different ms media without growth regulators and with normal level of sucrose (30 gl-1) (a), without growth regulators and with reduced sucrose (10 gl-1) (b) and medium supplemented with lmg gl-1 bap and 0.1 mgi1 iba and with 30 gi-1sucrose (c) for two weeks....

results however the maximum production of avermectin b1b (17 mg/l) was obtained by using sm2 growth medium containing soluble corn starch, yeast extract, kcl, caco3 and mgso4 which was detected qualitatively by using tlc and quantitatively by hplc. conclusions maximum production was observed with initial medium ph of 7, 10% inoculum size with incubation temperature of 31°c for 10 days of fermen...

We consider a system of two porous medium equations defined on two different components of the real line, which are connected by the nonlinear contact condition ux = vx , v = ψ(u) on the contact line S. First we prove existence and uniqueness of a solution (u, v) on a bounded domain. Furthermore, we are interested in the behaviour of the interface of the porous medium equation when it crosses t...
