Shifted Darboux transformations of the generalized Jacobi matrices, I
Let J be a monic generalized Jacobi matrix, i.e., a three-diagonal block matrix of a special form. We find conditions for a monic generalized Jacobi matrix J to admit a factorization J = LU + Ξ±I with L and U being lower and upper triangular two-diagonal block matrices of special forms. In this case, the shifted parameterless Darboux transformation of J defined by J(p) = UL+Ξ±I is shown to be also a monic generalized Jacobi matrix. Analogs of the Christoffel formulas for polynomials of the first and second kinds corresponding to the Darboux transformation J(p) are found

Yu.V. Buidin for help in systematical
classification of plants.Aim: The aim of the work was isolation and identification of the phenolic compounds from the rhizomes
of Iris hungarica.
Materials and methods: To establish by chemical and spectral methods for the structures of phenolic
compounds, which were isolated from the rhizomes of Iris hungarica Waldst. et Kit. (Iridaceae family).
Compounds were obtained by column chromatography on silica gel and their structures were determined
by UV, IR, MS, 1H-NMR spectra methods. Preliminary screening of antibacterial activity was
determined.
Results: From the ethanolic extract of the rhizomes of I. hungarica, which is widespread in Ukraine, for
the first time two new for this species isoflavones, teΡtorigenin and tectoridin and xanthone mangiferin,
together with known isoflavonoids daidzein, genistein, formononetin were isolated. The dry extract
of the rhizomes of I. hungarica at a concentration of 1% has shown the highest inhibitory activity for
Gram-positive bacteria and fungi.Objetivo: El objetivo del trabajo es el aislamiento y la identificaciΓ³n de los compuestos fenΓ³licos de los

Analogues of Shepherdson's Theorem for a language with exponentiation
In 1964 Shepherdson \cite{shepherdson:1964} proved the following fact: a
discretely ordered semiring satisfies (open, or
quantifier free, induction) iff the corresponding ring is an
integer part of the real closure of the quotient field of . In
this paper, we consider the open induction in the expanded languages with the
exponentiation and the power function and try to find a similar criterion for
models of these theories.
For several expansions of the theory of real closed fields we
obtain analogues of Shepherdson's Theorem in the following sense: if an
exponential field is a model of and discretely ordered
ring is an (exponential) integer part of , then
is a model of the open induction in the expanded language. The
proof of the opposite implications remains an open question, but for some
finite extension of the usual open induction we can prove the following
theorem: for any discretely ordered ring holds
satisfies this finite extension iff there is an exponential real closed field
with the Bernoulli inequality such that is an
exponential integer part of . After that, we consider a nonstandard
o-minimal exponential field, constructed in
\cite{vandendries_macintyre_marker:2001} and using it and the results above,
construct nonstandard models of the open induction in the expanded languages
and obtain independence results

Species of Iris genus (Iridaceae) have a long history of traditional medicinal use in different countries as alternative aperient, tonic, cathartic, diuretic, gall bladder diseases, liver complaints, dropsy, purification of blood, venereal infections, fever, bilious infections and for a variety of heart diseases. The rhizomes of Iris are the rich source of the secondary metabolites, in which flavonoids predominate. The clinical studies of substances from irises gave positive results in the treatment of cancer, bacterial and viral infections. Continuing the search of new biologically active compounds from the plants of Iridaceae family for the first time three isoflavones that are new for this species β irigenin, iristectorigenin B and its glucoside iristectorin B have been isolated from the ethanolic extract of the rhizomes of Iris hungarica Waldst. et Kit., which is widespread in Ukraine. The structure of the compounds is described as 5,7,3β-trihydroxy-6,4β,5β-trimethoxyisoflavone, 5,7,4β-trihydroxy-6,3β-dimethoxyisoflavone and iristectorigenin B-7-O-Ξ²-D-glucoside, respectively. The compounds were obtained from the ethyl acetate fraction of the iris rhizomes by column chromatography on silica gel with sequential elution of the chloroform β ethanol solvent with different concentrations. The structure of the compounds has been determined by chemical and spectral methods and in comparison with the literature data.Π Π°ΡΡΠ΅Π½ΠΈΡ ΡΠΎΠ΄Π° Iris (Iridaceae) ΠΈΠΌΠ΅ΡΡ Π΄Π°Π²Π½ΡΡ ΠΈΡΡΠΎΡΠΈΡ ΠΏΡΠΈΠΌΠ΅Π½Π΅Π½ΠΈΡ Π² ΡΡΠ°Π΄ΠΈΡΠΈΠΎΠ½Π½ΠΎΠΉ ΠΌΠ΅Π΄ΠΈΡΠΈΠ½Π΅ ΡΠ°Π·Π»ΠΈΡΠ½ΡΡ
