Cropping systems for spring and winter cereals under simulated pasture: Yield and yield distribution
The ratio of symmetry energy coefficient relative to the temperature, asym/T , has been extracted as a function of Z from the variance of the observed isotope distributions from the experiments described in Ref.[1]. In order to explore the relation between the symmetry energy term in the free energy and the variance of the isotope distribution, Ono et al. introduced a generalized function K(N,Z...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
In the hotel sector, yield management traditionally balances a supply of perishable room nights against demand by manipulating price and time of consumption. While widely accepted, Internetbased distribution channels with different cost structures complicate the process. Hotels must not only manipulate price in response to supply and demand, but must also choose which portfolio of distribution ...
Much effort has been devoted to the synthesis of gold nanoparticles with different shapes, including the zero-dimensional nanospheres, one dimensional nanorods, and two-dimensional nanoplates. Compared to zero or one dimensional nanostructures, the synthesis of two-dimensional nanostructures in high yield has always been more involved, often requiring complex and timeconsuming steps such as mor...
The spatial variation of crop yield was mainly caused by the complicated factors, such as soil and land factors. Based on sound theoretical reasoning, the paper performed an exploratory investigation of the relationship between the spatial distribution of yield measurement about 849 samplings on Thiessen polygon. Reasonable sample size or sampling density is an assurance of yield estimation sur...
