in order to examine the effects of essential oils and silver nanoparticles as anantimicrobial preservative in the solutions of alstroemeri cv. sukari cut flowers, anexperiment was conducted with 11 treatments and 3 replications in a completelyrandomized design. in this study, we used essences of carvacrol, thymol and zataria oilwithconcentrations of 50 and 100 mg l-1 and silver nanoparticles wi...

We show that Whitham type equations u_t + u u_x -L = 0, where L is a general Fourier multiplier operator of order \alpha \in [-1,1], \alpha\neq allow for small solutions to be extended beyond their expected existence time. The result valid range quadratic dispersive with inhomogeneous symbols in the given by \alpha, and should extendable other same relative strength.

the postharvest life of cut eustoma grandiflorum flowers is limited in open flowers. therefore a factorial experiment based on a completely randomized design with ascorbic acid (asa) at 4 levels (0, 100, 200, 300mg l-1) and citric acid (ca) at 3 levels (0, 100, 200 mg l-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. results indicated that a significa...

Seeds of the palm Attalea butyracea (formerly known as Scheelea zonensis in Panamá and Scheelea rostrata in Costa Rica—Bradford & Smith 1977, Forget et al. 1994, Henderson 1995) are contained within stony endocarps. For the purposes of this paper, individual fruits or their seed-bearing endocarps will be referred to as diaspores; all of the seeds of a given fruit are surrounded by the stony wal...
