MAIN-SEQUENCE EFFECTIVE TEMPERATURES FROM A REVISED MASS–LUMINOSITY RELATION BASED ON ACCURATE PROPERTIES

Luminosity-metallicity relation for stars on the lower main sequence

We present a comparison of the predictions of stellar models with the luminosity of the lower main sequence (5.5 < MV < 7.3) using K dwarfs in the Hipparcos catalog. The parallaxes of our comparison stars are known to better than 15% and metallicities have been recently determined from photometry. A major advantage of our comparison is that distances in our sample are known with good accuracy, ...

translation of collocations from english into persian, based on ghazalas theory

غزالا همایندها را به صورت ترکیبی از دو یا چند واژه که همواره در متون مختلف زبان ها همراه با هم می آیند تعریف می نماید. از دیدگاه او روند رو به رشد میل به ترجمه ی همایندها در مطالعات ترجمه، به دلیل اهمیت آنها در انسجام ساختار زبان است. این پایان نامه اساسا به ترجمه ی همایندها منحصر شده است. هدف آن بررسی کاربرد راهکارهای غزالا در مورد ترجمه ی همایندها از انگلیسی به فارسی است. هدف دیگر آن یافتن پر...

Comment on “ Accurate relativistic effective potentials for the sixth - row main group elements ”

Comment on " Accurate relativistic effective potentials for the sixth-row main group elements " [J. Abstract Critical remarks in respect to the Generalized Relativistic Effective Core Potential in the recent article of S. A.

Development in Rice Genome Research Based on Accurate Genome Sequence

Rice is one of the most important crops in the world. Although genetic improvement is a key technology for the acceleration of rice breeding, a lack of genome information had restricted efforts in molecular-based breeding until the completion of the high-quality rice genome sequence, which opened new opportunities for research in various areas of genomics. The syntenic relationship of the rice ...
