erodium (geranaiceae) species are distributed in different habitats of iran. some species are of medicinal importance while some are well known weeds. there are no chromosome counts for erdoium species of iran. chromosome numbers are given for six taxa of erodium (geraniaceae) from iran: e. cicutarium (2n=36), e. ciconium(2n=18), e. malacoides (2n=20), e. moschatum (2n=20), e. neuradifolium (2n...

This paper introduces Chain sampling plan for generalized exponential distribution when the life-test is truncated at a prespecified time are provided in this manuscript. It is assumed that the shape parameter of the generalized exponential distribution is known. The design parameters such as the minimum sample size and the acceptance number are obtained by satisfying the producer’s and consume...

Zipf’s law appears in many application areas but does not have a closed form expression, which may make its use cumbersome. Since it coincides with the truncated version of the Zeta distribution, in this paper we propose three approximate closed form expressions for the truncated Zeta distribution, which may be employed for Zipf’s law as well. The three approximations are based on the replaceme...

To find the most suitable indicator of viral and parasitic contamination of drinking water, large-volume samples were collected and analyzed for the presence of pathogens (cultivable human enteric viruses, Giardia lamblia cysts, and Cryptosporidium oocysts) and potential indicators (somatic and male-specific coliphages, Clostridium perfringens). The samples were obtained from three water treatm...

Abstract In this article we present tmvtnorm, an R package implementation for the truncated multivariate normal distribution. We consider random number generation with rejection and Gibbs sampling, computation of marginal densities as well as computation of the mean and covariance of the truncated variables. This contribution brings together latest research in this field and provides useful met...

We propose truncated and power-transformed (TPT) models for daily rainfall and we derive the Generalized Extreme Value (GEV) limit distributions for these models. We find that these limit distributions belong to the domain of attraction of the Fréchet family when the parent distribution of the daily values is a TPT t-Student model. In this case the shape parameter of the limiting GEV model depe...

Chain sampling plan for Log Logistic distribution when the life-test is truncated at a prespecified time is discussed. The design parameters such as the minimum sample size and the acceptance number necessary to assure a specified mean life time are obtained by satisfying the producer’s and consumer’s risks at the specified quality levels, under the assumption that the termination time and the ...

introduction: omp31 is animmunodominant and protective antigen conserved in brucella species and a good candidate for vaccine design. material & methods: the present study aimed at in silico design of the truncated omp31 (tomp31) using bioinformatic tools and to express the selected form in escherichia coli (e. coli) results and conclusion: various bioinformatically calculated scores for the mo...
