Increasing crop production at a time of rapid climate change represents the greatest challenge facing contemporary agricultural research. Our understanding of the genetic control of yield derives from controlled field experiments designed to minimize environmental variance. In spite of these efforts there is substantial residual variability among plants attributable to Genotype × Environment in...
So, you want to write a letter to the editor? A recent editorial by Golub in JAMA prompted us to outline more fully our vision of Annals of Emergency Medicine’s Correspondence section and its place within the journal and the peer review process. Like most peer-reviewed publications, Annals of Emergency Medicine contains a correspondence section, commonly known as Letters to the Editor. Journals...
We show that recent γ-ray observations of the Small Magellanic Cloud with EGRET rule out a universal cosmic ray flux only at energies below ≈ 10 GeV, while the observed diffuse X-ray and γ-ray background radiations have already ruled out, by more than three orders of magnitude, a universal extragalactic cosmic ray flux identical to that observed in the local solar neighborhood at energies below...
Different high energy interaction models are the applied in CORSIKA code to simulate Extensive Air Showers (EAS) generated by Cosmic Rays (CR). In this work the effects of QGSJET01, QGSJETII, DPMJET, SIBYLL models on Xmax and multiplicity of secondary electrons and muons at observation level are studied.
Research on the cosmic microwave background (CMB) is progressing rapidly. New experimental groups are popping up and two new satellites will be launched. The current enthusiasm to measure fluctuations in the CMB power spectrum at angular scales between 0 • .1 and 1 • is largely motivated by the expectation that CMB determinations of cosmological parameters will be of unprecedented precision: co...
“Fronti Nulla Fides”: No reliance can be placed on appearance. In a letter to the editor (AI Mugazine, Winter 1989), Benjamin Kuipers criticizes various points made in an earlier paper of ours (Akman and ten Hagen 1989). First, a side (nonetheless important) remark: Although Kuipers asserts that he distributes QSIM to interested researchers, our experience has been otherwise. Akman has tried tw...
the present research deals with verbal and visual values of the persian alphabet. man had achieved common results in this respect in the course of the history, and graphical forms are believed to act as a strong bridge between the man and the universe. the theoretical research is aimed at responding to fundamental questions in this respect including those concerning scientific and historical re...
mohammad’s invitation letters, in addition to being sacred texts, include exact word combinations which are based on calculated and systematic arrangements of words and sentences. stylistics is a linguistic science which study texts along four dimensions: syntax, morphology, phonology, and signification. this science guides its audience and users to become aware of and enjoy interrelated and or...

One of the most important QC tests of whole-cell pertussis vaccine (WCPV) is potency test. In this regard, mouse protection test (MPT) is the current potency method, which is associated with severe animal distress and large variability in results. The purpose of this study was to assess Pertussis Serological Potency Test (PSPT) as a serological alternative method to intracerebral challenge in M...
