Rna Synthesis in Chromosome Connectives
Connections between chromosomes have been observed and described by numerous investigators (1-10). They have been seen with the light microscope (I, 2, 6, 7, 10), the transmission electron microscope (3-5, 8), and the scanning electron microscope (9). In addition, surface specializations (side arms, loops, whiskers) have been observed on chromosomes by a number of researchers who have employed ...
متن کاملSynthesis of messenger RNA and chromosome structure in the cellular slime mold.
This paper summarizes our knowledge of the structure and biosynthesis of messenger RNA in the slime mold Dictyostelium discoideum, the arrangement of DNA sequences in the Dictyostelium chromosome, and the changes in the pattern of predominant polypeptides synthesized during Dictyostelium development.
متن کاملGenerating Connectives
We present an implemented procedure to select an appropriate connective to link two propositions, which is part of a large text generation system. Each connective is defined as a set of constraints between features of flxe propositions it connects. Ore' focus has been to identify pragmatic features flint can be produced by a deep generator to provide a simple representation of connectives. Usin...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Connectives in Cumulative Logics
Cumulative logics are studied in an abstract setting, i.e., without connectives, very much in the spirit of Makinson’s [11] early work. A powerful representation theorem characterizes those logics by choice functions that satisfy a weakening of Sen’s property α, in the spirit of the author’s [9]. The representation results obtained are surprisingly smooth: in the completeness part the choice fu...
