abstract the purpose of this paper is to investigate the factors affecting adoption of agricultural crops insurance among apple growers in semirom and eghlid shahrestans and determining the best model. a survey was conducted using the stratified random sampling. data were collected by questionnaire from 240 adopters and 157 non – adopters. the results showed that adopters of insurance are more ...
In this paper, we investigate the multiplicity of charged particles in e+ e– annihilation by using different models. To achieve this we first fit the multiplicity distribution of charged particles in the energy range of 54-57 GeV by using both the Poisson distribution and KNO scaling, then we compare these results with multiplicity distribution at the lower energies. This comparison shows that...
Increasing the water use efficiency through promotion of sprinkler irrigation system, in order to increase production, has been the aim of the Ministry of Agricultural-Jihad in the past decade. Considerable amount of investment and efforts have been devoted to this end. Therefore, investigation of these efforts and development of models to predict the adoption behavior of farmers are of conside...

Passive methods of nuclear safeguards determine the important parameters an unknown sample from statistics detection neutrons emitted item. These latter are due to spontaneous fissions and (α,n) reactions, enhanced by internal multiplication before leaking out. Based on original work Böhnel, methodology traditional multiplicity counting is based first three factorial moments number neutrons, on...
a new model based on a combination of the polymeric multigrain and multilayer models has been developed to predict the polymerization rate, particle growth, morphology, effective parameters on broadening of the molecular weight distribution, number and weight average of the molecular weight, isotacticity index and bulk density of polymer. mathematical correlations and the kinetics used in this ...

For a region of the nearest-neighbour ferromagnetic Ashkin–Teller spin systems on Z2, we characterize the existence of multiple Gibbs states via percolation. In particular, there are multiple Gibbs states if and only if there exists percolation of any of the spin types (i.e. the magnetized states are characterized by percolation of the dominant species). This result was previously known only fo...
