abstract one basic method of improving rangelands in a country is the use of native as well as exotic species of plants adaptable. among the but introduced species, atriplex canescens has been introduced in many rangelands, but it is important and necessary to consider it’s effects on native species. in the current study the effect of chemical competition (allelopathy) of atriplex canescens on ...

Three closely related Salsola taxa (Salsola boissieri Botsch. subsp. serpentinicola (Freitag & Özhatay) Freitag Uotila, boissieri, turcica Yıldırımlı (halophytic ecotype), (gypsicole ecotype)) from different edaphic conditions were studied according to changing light and salinity conditions. Seeds of target collected in 2017 their weights determined. The perianth segments removed before...

The Geobacillus icigianus G1w1(T) strain was isolated from sludge samples of unnamed vaporing hydrothermal (97°С) outlets situated in a geyser in the Troinoy region (Valley of Geysers, Kronotsky Nature Reserve, Kamchatka, Russian Federation; 54°25'51.40″N, 160°7'41.40″E). The sequenced and annotated genome is 3,457,810 bp and encodes 3,342 genes.

A theory of higher-derivative 2D dilaton gravity which has its roots in the massive higherspin mode dynamics of string theory is suggested. The divergences of the effective action to one-loop are calculated, both in the covariant and in the conformal gauge. Some technical problems which appear in the calculations are discussed. An interpretation of the theory as a particular D=2 higher-derivati...

We investigate the influence of the projective invariance on the renormalization properties of the theory. One-loop counterterms are calculated in the most general case of interaction of gravity with scalar field.
