The infrared spectrum of sunspots is analyzed in the H-band region (5540–6997 cm 1) with the aid of a new, hot (T 1⁄4 1800 K) laboratory emission spectrum of water covering 4878–7552 cm 1. There are 682 lines in the sunspot spectrum and 5589 lines in the laboratory spectrum assigned quantum numbers corresponding to transitions due to H2O using a combination of previously known experimental ener...
A model of a three Pomeron contribution to high energy elastic pp and p̄p scattering is proposed. The data are well described for all momenta (0.01 ≤ |t| ≤ 14. GeV 2) and energies (8. ≤ √s ≤ 1800. GeV ) (χ2/d.o.f. = 2.60). The model predicts the appearance of two dips in the differential cross-section which will be measured at LHC. The parameters of the Pomeron trajectories are: α(0)P1 = 1.058, ...
زمینه و هدف: آلوپسی آندروژنتیک شایعترین شکل ریزش موی پیشرونده منتشر و قرینه می باشد که هر دو جنس را مبتلا می کند. الگوی ریزش مو و پاتوفیزیولوژی آن در دو جنس متفاوت می باشد. طبقه بندی های متفاوتی برای ریزش مو در زنان ارائه شده است ازجمله طبقه بندی ludwig، hamilton، chirstmas tree و early onset hairloss. روش اجرا: این مطالعه یک مطالعه توصیفی است که در سال های 1388-1387 در آرایشگاه های شهر اصفهان ...
This article examines the status of midwives in the early modern period (1400-1800). More particularly, it examines midwives’ practice, education, skills and competence, social background, public life and image as well as the way they were regarded by their clients, in an era prior to their decline and the increase in medical intervention during childbirth. Due to bulk of information this study...
The phenomenology of heavy quarkonia production in hadron collisions is reviewed. The theoretical predictions are compared to data. Commonly used production models are shown to fail in explaining all the experimental findings. The shortcomings of these models are analysed and possible improvements are discussed. FNT/T-95/14 hep-ph/9505332 May 1995 Invited talk at the XXX Rencontres de Moriond, ...
