Basically the only existing theories for the creation of a magnetic field (B) in the Universe are the creation of a seed field ∼ 10 G in spiral galaxy which is subsequently supposedly amplified up to the observed 10—10 G by a dynamo process or a seed intergalactic field of ∼ 10—10 G which is amplified by collapse and differential rotation. No satisfactory dynamo theory, however, exists today. W...

background: brown rice (br) is unpolished rice with various beneficial compounds such as vitamins, magnesium and other minerals, dietary fiber, essential fatty acids, γ‑oryzanol and γ‑aminobutyric acid. in the present study, we compared the effects of white rice (wr) and br on inflammatory marker high‑sensitivity c‑reactive protein (hs‑crp) and cardiovascular risk factors among non‑menopausal o...

caspian brown trout (salmo trutta caspius) is one of the economically valuable species in the caspian sea. artificial propagation and production of larvae are the main problems in the early culture of this species. the purpose of this paper is to study the effect of reproductive performance of female broods on opposition reproduction efficiency in caspian brown trout in the breeding season of 2...

In a recent paper, three economists — Drusilla Brown, Alan Deardoff, and Robert Stern — attempt to calculate the benefits of trade liberalization. They estimate that complete elimination of all trade barriers in the world would add $1.9 trillion (about 5%) to the world's gross economic product by 2005 (Brown, Deardoff, and Stern 2001). Brown-Deardoff-Stern's numbers look convincing, leaving the...

Brown spot caused by Bipolaris oryzae is an important rice disease in Southern coast of Caspian Sea, the major rice growing region in Iran. A total of 45 Trichoderma isolates were obtained from rice paddy fields in Golestan and Mazandaran provinces which belonged to Trichoderma harzianum, T. virens and T. atroviride species. Initially, they were screened against B. oryzae by antagonism tests in...

The rich physics exhibited by random optical wave fields permitted Hanbury Brown and Twiss to unveil fundamental aspects of light. Furthermore, it has been recognized that optical vortices are ubiquitous in random light and that the phase distribution around these optical singularities imprints a spectrum of orbital angular momentum onto a light field. We demonstrate that random fluctuations of...

purpose : to determine the distribution of iris colors in the population of tehran and to assess possible associations between iris color and ocular disorder methods : through a stratified random cluster sampling approach, 160 clusters were selected in different municipality districts of tehran, and the approached households were invited to a clinic. after the initial interview, all participant...

The popularity of the concept of communities is growing, and so are ideas on how to support these communities with technologies. We see this especially in the field of management and organization studies where communities are increasingly seen as a solution for the problems of rigid, hierarchical and conservative bureaucratic structures. According to some scholars, communities are the latest wa...

We consider a strictly stationary random field on the two-dimensional integer lattice with regularly varying marginal and finite-dimensional distributions. Exploiting regular variation, we define spatial extremogram which takes into account only largest values in field. This is autocovariance function. corresponding extremal spectral density its estimator, periodogram. Based periodogram, Whittl...

brown-vialetto-van laere syndrome (bvvls) is a rare neurological disorder. we report our finding about four patients clinically and electrophysiologically diagnosed as bvvls and denoted their clinical features with comparison to previous reports. the first symptom was bilateral hearing loss and the onset of other cranial nerves involvement varied between 0-15 years. our patients represented som...
