Moğolların Ön Asya coğrafyasına gelmesi ile bölgede idarî ve kültürel açıdan yeni bir dönemin başladığını görmekteyiz. İdarî değişim dönemi olan bu zaman diliminde, İslâm medeniyetinin unsurları Bozkır Medeniyeti’nin parçası Moğol geleneklerinin iç içe geçerek 1231 yılından İlhanlı Devleti’nin yıkılışına kadar Asya’da yönetimi oluşturan bütün sistemlere yerleştiğini Yargı sistemi açısından döne...

Aims. We discuss and characterize micro-lensing among the 3 brightest lensed images (A-B-C) of the gravitational lens system RXS J1131-1231 (a quadruply imaged AGN) by means of long slit optical and NIR spectroscopy. Qualitative constraints on the size of different emission regions are derived. We also perform a spectroscopic study of two field galaxies located within 1.6 arcmin radius from the...

We present a source and lens reconstruction for the optical Einstein ring gravitational lens system RXS J1131-1231. We resolve detail in the source, which is the host galaxy of a z = 0.658 quasar, down to a resolution of 0.045 arc seconds (this is the size of the smallest conclusively resolved structures, rather than the pixel scale), using a Bayesian technique with a realistic model for the pr...

BACKGROUND Correct staging of puberty is essential in order to differentiate different pathologies, as various components of the endocrine system influence breast, pubic, and axillary hair development. AIMS To determine the current timing of adrenarche and breast development in Lithuanian preadolescent schoolgirls. METHODS Cross-sectional study of 1231 schoolgirls aged 7.0-11.6 years. Puber...
