evidence of adverse selection in irans health insurance market
در این تحقیق به مطالعه وجود انتخاب نامساعد(کژ گزینی) در بازار بیمه درمان تکمیلی ایران پرداخته شده است. داده های مورد نیاز توسط پرسشنامه و به روش نمونه گیری خوشه ای جمع آوری شده است. پرسشنامه ها در میان افراد شاغل ساکن شهر تهران توریع شد. در این تحقیق با استفاده از تخمین دو مدل لجستیک و به دست آوردن ضریب همبستگی میان تقاضای بیمه درمان تکمیلی و رخداد خسارت به بررسی موضوع مورد نظر پرداخته شده است....
15 صفحه اولSize Selection by Cluster Deflection in an Electric Field
Defection by an electricfield has been tested asameans to deposit size selected clusters. A hollow-cathode, glow-discharge, source has been used for the production of Cu clusters in the size range between 4 and 38 nm, while afield emission scanning microscope has been usedfor HREM investigation of the size and morphology of clusters supported on Alfoil. The deflected negative clusters demonstra...
متن کاملThe Dyn~cs O\ Levitated Drops in an Electric Field
Ultrasonic and electrostatic levitation techniques have allowed the experimental investigation of the nonlinear oscillatory dynamics of free droplets with diameter between 0.1 and 0.4 cm. The measurement of the resonance frequencies of the fust three normal modes of large amplitude shape oscillations in an electric field of varying magnitude has been carried out with and without surface charges...
متن کاملImaging enhanced energy transfer in a levitated aerosol particle
Energy transfer experiments are carried out at dilute concentrations of donors ~10 M , coumarine 334! and acceptors ~5310 M , sulforhodamine 101! in a levitated microdroplet ~diameter, 2a519 mm!, using an aerosol particle fluorescence microscope. Microphotographs in donor and acceptor luminescence show that the transfer mechanism is not of a Förster type, but is mediated by morphology dependent...
متن کاملExploring NOy chemistry in levitated aqueous aerosol droplets
Atmospheric aerosol Atmospheric aerosol is a variable, yet critical component of the climate system and has substantial impact on climate change. [1-3] Aerosols affect climate directly, by scattering and absorbing solar radiation, and indirectly, by acting as cloud condensation nuclei, CCN. Clouds may reduce the incident radiation on the surface, increase or decrease temperatures, and suppress ...
