کمیته اروپائی بتن ( C E B)

مهر ماه امسال توفیقی دست داد که در شانزدهمین دوره اجلاسیه کمیته اروپائی بتن ، منعقد در لندن ، شرکت نمایم . جلسات دوره اجلاسیه و مدارکی که برا ی بحث و تبادل نظر در این جلسات ارائه گردید باندازه ای غنی و جالب بود که طی یازده سال همکاری با کمیته اروپائی بتن نظیر آن را ندیده بودم . روی این اصل تصمیم گرفتم بمحض مراجعت به ایران با نوشتن چند سطری این سازمان بین المللی را به مهندسان و کسانیکه بنحوی از ...

9606232 May , 1996 R b PROBLEM : LOOP CONTRIBUTIONS AND SUPERSYMMETRY

I summarize a part of the work done with Bamert, Burgess, London and Nardi, 1 in which we find simplified expressions for the possible one-loop contributions to the R b parameter from new virtual particles, including supersymmetric ones. Our expressions make it easier to identify which models and choices of parameters are best able to solve the R b problem. The evidence for a discrepancy betwee...

A polarization study of comet Hyakutake ( C / 1996 B 2 )

Observations for the linear polarization of comet Hyakutake (C/1996B2) are carriedout at three continuumwavebands: 3650Å, 4845Å and 6840Å. These observations were taken on March 13 and March 18, 1996 when the phase angles were 38.1 and 36.9, respectively. These results indicate an increase in the degree of polarizationwith phase angle andwavelength, in general. Present results show that comet H...
