an investigation about the relationship between insurance lines and economic growth; the case study of iran
مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولThe onset of General Relativity: Gravitationally redshifted emission lines
We study and quantify gravitational redshift by means of relativistic ray tracing simulations of emission lines. The emitter model is based on thin, Keplerian rotating rings in the equatorial plane of a rotating black hole. Emission lines are characterised by a generalized fully relativistic Doppler factor or redshift associated with the line core. Two modes of gravitational redshift, shift and...
متن کاملSharp Lines in the Spectrum of Nova
FernalcTs discovery of the recent outburst of Nova RS Ophiuchi on July 14.1, 1958 (UT) was telephoned to the Mount Wilson Observatory from Berkeley by Dr. Leland E. Cunningham. The star reached maximum at about magnitude 5.0 later that night. It has since been reported that Peltier had observed the star at magnitude 11.1 on the previous night. I was the observer on the 60-inch telescope on the ...
متن کاملCultural Relativity of Moral Precepts
The foundation of most intellectual discourse is Western-centric to the exclusion of other views. This includes ideal patterns of social interaction, preference for aesthetic, accepted norms and values, and the concepts of dignity, respectability, morality and ethics. Such a position is culturally myopic. Western cultural influence colors all of them including moral precepts. The assumption is ...
متن کاملOptical spectrum of myeloperoxidase. Origin of the red shift.
The optical spectrum of reduced myeloperoxidase (EC 1.11.1.7) displays an unusual red shift of the Soret band which is at 472 nm and the alpha-band which is at 636 nm. The spectral properties of myeloperoxidase can be modified by means of acid treatment. Upon short exposure to acid (pH 1.7) the red-shifted optical absorption spectrum of the reduced enzyme (lambda max at 472 nm) was blue-shifted...
