Genetic Tumors of Nicotiana. I. Chemical Composition of N. glauca, N. langsdorffii, & Their F(1) Hybrid.
The F1 hybrid of Nicotiana glauca Grah. and N. langsdorffii Weinm. is well known for its spontaneous tumor-producing ability. Most investigations concerning plant tumors are in the field of genetics or cytology (2,4,6); a few deal with the free amino acid levels of N. glauca, N. langsdorffii and their hybrid (1, 3, 8). However, no references are available on the general chemical composition of ...
متن کاملF. F. F. F.—2000 A.d
During World War I there was much lamentation over the "defects of the draft," and the word "shocking" was in frequent use with reference to the condition of a large proportion of men of military age. When, more recently, it became necessary again for society to interpose a shield of human lives between itself and disaster, its cerebral cells once more became agitated over the report that its y...
متن کاملOn the Structure of Left and Right F-, Sm-and E-quasigroups
It is proved that any left F-quasigroup is isomorphic to the direct product of a left F-quasigroup with a unique idempotent element and isotope of a special form of a left distributive quasigroup. The similar theorems are proved for right F-quasigroups, left and right SM-and E-quasigroups. Information on simple quasigroups from these quasigroup classes is given, for example, finite simple F-qua...
متن کاملNomenclatural novelties in the Postia caesia complex
Within the genus Postia, the P. caesia complex forms a distinctive morphological group. Based on recent molecular data, the current taxonomic status of the P. caesia complex is discussed and the nomenclature of the related taxa is revised as well. New combinations are: Postia subg. Cyanosporus, Postia africana, Postia amyloidea, Postia caesioflava, and Postia coeruleivirens.
متن کاملf-DERIVATIONS AND (f; g)-DERIVATIONS OF MV -ALGEBRAS
Recently, the algebraic theory of MV -algebras is intensively studied. In this paper, we extend the concept of derivation of $MV$-algebras and we give someillustrative examples. Moreover, as a generalization of derivations of $MV$ -algebraswe introduce the notion of $f$-derivations and $(f; g)$-derivations of $MV$-algebras.Also, we investigate some properties of them.
