RD-flatness and RD-injectivity
It is proved that every commutative ring whose RD-injective modules are Σ-RD-injective is the product of a pure semi-simple ring and a finite ring. A complete characterization of commutative rings for which each artinian (respectively simple) module is RD-injective, is given. These results can be obtained by using the properties of RD-flat modules and RD-coflat modules which are respectively th...
متن کاملStructural Rd E Ocumentation: a Case Study
terns require a different approach to software documentation than has traditionally been used. In understanding large, evolving software systems, structural redocumentation through reverse engineering plays a key role. Reconstructing and effectively redocumenting the design of existing software systems is even more difficult than initial design. Recognizing abstractions in real-world systems is...
متن کاملEarly markers of retinal degeneration in rd/rd mice.
PURPOSE In the rd/rd mouse, the cell death of rod photoreceptors has been correlated to abnormal levels of the cyclic nucleotide cGMP within photoreceptors. Given that cGMP is required for opening of the cationic channels, there is the possibility that a high cGMP concentration would maintain these channels open, at a high energy cost for the retina. METHODS We investigated whether cation cha...

متن کاملمدولهای rd-پروژکتیو و rd-انژکتیو
پایان نامه حاضر به بررسی مدول های rd– پروژکتیو و rd– انژکتیو می پردازد. سپس پوش و پوشش rd– پروژکتیو و rd– انژکتیو را تعریف کرده و آنها را مورد مطالعه قرار می دهد. بعدهای rd– انژکتیو و rd- پروژکتیو را برای مدول ها و حلقه ها تعریف می کند و روابط آنها را با ابعاد انژکتیو و پروژکتیو می سنجد و در پایان با تعریف تابعگونextrd(-,-) به بررسی رابطه آن با تابعگونext(-,-)می پردازد.تمرکز ما در این پایان نام...
