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...

The SIMP approach is one of the most frequently used methods for topology optimization of structures. In this method, the relative density is expressed as a function of coordinates and varies from 0 to 1 within the design domain. Relative densities of 0 and 1 are associated to the existence and non-existence of the material, respectively. The finite element approach is usually utilized to analy...

in order to evaluate the efficiency of empirical competition models for simulation of sugar beet (beta vulgaris l.) yield at interference with redroot pigweed (amaranthus retroflexus l.), a factorial experiment based on randomized complete block design with three replications was carried out. factors were weed densities (d1=1, d2= 4, d3= 8, d4=12 and d5=16 plants m-1 of row) and relative time o...

We determine the relative pion mass shift Mπ(L)/Mπ − 1 due to the finite spatial extent L of the box by means of two-flavor chiral perturbation theory and the one-particle Lüscher formula. We use as input the expression for the infinite volume ππ forward scattering amplitude up to next-to-next-to-leading order and can therefore control the convergence of the chiral series. A comparison to the f...

Different theories of bodily tides assume different forms of dependence of the angular lag 8 upon the tidal frequency %. In the old theory (Gerstenkorn 1955, MacDonald 1964, Kaula 1964) the geometric lag angle is assumed constant (i.e., 8 ~ x), while the new theory (Singer 1968; Mignard 1979, 1980) postulates constancy of the time lag At (which is equivalent to saying that 8 ~ j} ). Each partic...

The drying of hydrogel films formed by poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) block copolymers (Pluronic P105 and Pluronic L64) is investigated at various air relative humidity (RH) conditions in the range 11-94%. These amphiphilic block copolymers self-assemble to form a variety of ordered (lyotropic liquid crystalline) structures as the water content decreases. The amount of wat...
