This letter extends recent work by Bahmani-Oskooee (Bahmani-Oskooee, M., Do exchange rates follow a random walk process in Middle Eastern countries? Economics Letters 1998;58:339–344) on testing long-run purchasing power parity for Middle Eastern countries during the post-Bretton Woods period. Using multivariate nonlinear models, strong support is provided for highly nonlinear reversion of real...

It was generally assumed that weak van der Waals interactions exist between neighboring layers in the two-dimensional group-IV chalcogenides. Using PbSe as a prototypal example, however, we find additional strong coupling Pb-Pb layers, evidenced by detailed analysis of differential charge density. The resembles covalent-like bond and exhibits harmonicity around equilibrium distance, which can b...

A bioassay of 3-amino-4-ethoxyacetanilide for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. 3-Amino-4-ethoxyacetanilide was administered in the feed, at either of two concentrations, to groups of approximately 50 male and 50 female animals of each species. The dietary concentrations used in the chronic bioassay for low and high dose rats were 0.4 and 1.5 percent...

A bioassay for the possible carcinogenicity of technical-grade 4-chloro-o-phenylenediamine was conducted using Fischer 344 rats and B6C3F1 mice. 4-Chloro-o-phenylenediamine was administered in the feed, at either of two concentrations, to groups of 49 or 50 male and 50 female animals of each species. For male and female rats, the high and low time-weighted average dietary concentrations of 4-ch...

to evaluate the effect of water, tape drip and furrow irrigation methods on the performance components and features of agria cultivar potato, an experiment was carried out in the agriculture faculty of kermanshah. repeated three times, this study was carried out in the form of full random blocks with the main factor of different amounts of irrigation water in three levels (50, 75, and100 percen...

Background: Leisure time activities might be associated with school performance. This study aimed to investigate the association between leisure time variables, including television and computer using time, homework time and cell phone using time, with children’s school performance in a nationally representative sample of Ira...

Application of smoke condensate derived from an indirect heating of jennet feces (Sargin) had been recommended by Iranian ancient scientists as a therapeutic agent. The present study was done to evaluate the healing effects of Guajol® ointment on burn wound in rat. The Guajol® ointment was prepared from the smoke condensate of Sargin sampl...

A bioassay for possible carcinogenicity of p-anisidine hydrochloride was conducted using Fischer 344 rats and B6C3F1 mice. p-Anisidine hydrochloride was administered in the feed, at either of two concentrations, to groups of 55 male and 55 female animals of each species. Fifty-five animals of each sex and species were placed on test as controls. The high and low dietary concentrations of p-anis...

A bioassay for the possible carcinogenicity of N-(1-naphthyl)ethylenediamine dihydrochloride was conducted using Fischer 344 rats and B6C3F1 mice. N-(1-Naphthyl)ethylenediamine dihydrochloride was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species. Twenty-five rats of each sex and 50 mice of each sex were placed on test as contr...
