The coisotropic subgroup structure of SL_q(2,R)

We study the coisotropic subgroup structure of standard SL_q(2,R) and the corresponding embeddable quantum homogeneous spaces. While the subgroups S^1 and R_+ survive undeformed in the quantization as coalgebras, we show that R is deformed to a family of quantum coisotropic subgroups whose coalgebra can not be extended to an Hopf algebra. We explicitly describe the quantum homogeneous spaces and their double cosets.Comment: LaTex2e, 10pg, no figure

Professional identity of future financiers as the basis of professional culture

Розкрито суть професійної ідентичності як складного, багатофункціонального явища, яке тісно пов’язано з професійним самовизначенням і формується в процесі професійної підготовки майбутніх фінансистів. З'ясовано, що за своєю суттю професійна ідентичність має тісний взаємозв’язок із загальною культурою, системою цінностей, професіоналізмом і компетентностями фахівця, пов’язана зі змінами в структурі особистості. Автор вважає, що цілком ймовірно розглядати її як основу формування професійної культури майбутніх молодших фахівців з фінансів і кредиту.The essence of professional identity as a complex, multifunctional phenomenon, which is closely connected with professional self-determination and is formed in the process of professional training of future financiers, is disclosed. It has been found out that, in essence, professional identity has a close relationship with the general culture, system of values, professionalism and competence of a specialist associated with changes in the structure of the individual. The author believes that it is quite possible to consider it as the basis for the formation of a professional culture of future junior specialists in finance and credit

Highly hydrolytic reuteransucrase from probiotic Lactobacillus reuteri strain ATCC 55730

Lactobacillus reuteri strain ATCC 55730 (LB BIO) was isolated as a pure culture from a Reuteri tablet purchased from the BioGaia company. This probiotic strain produces a soluble glucan (reuteran), in which the majority of the linkages are of the α-(1→4) glucosidic type (∼70%). This reuteran also contains α-(1→6)- linked glucosyl units and 4,6-disubstituted α-glucosyl units at the branching points. The LB BIO glucansucrase gene (gtfO) was cloned and expressed in Escherichia coli, and the GTFO enzyme was purified. The recombinant GTFO enzyme and the LB BIO culture supernatants synthesized identical glucan polymers with respect to linkage type and size distribution. GTFO thus is a reuteransucrase, responsible for synthesis of this reuteran polymer in LB BIO. The preference of GTFO for synthesizing α-(1→4) linkages is also evident from the oligosaccharides produced from sucrose with different acceptor substrates, e.g., isopanose from isomaltose. GTFO has a relatively high hydrolysis/transferase activity ratio. Complete conversion of 100 mM sucrose by GTFO nevertheless yielded large amounts of reuteran, although more than 50% of sucrose was converted into glucose. This is only the second example of the isolation and characterization of a reuteransucrase and its reuteran product, both found in different L. reuteri strains. GTFO synthesizes a reuteran with the highest amount of α-(1→4) linkages reported to date

CQG algebras: a direct algebraic approach to compact quantum groups

The purely algebraic notion of CQG algebra (algebra of functions on a compact quantum group) is defined. In a straightforward algebraic manner, the Peter-Weyl theorem for CQG algebras and the existence of a unique positive definite Haar functional on any CQG algebra are established. It is shown that a CQG algebra can be naturally completed to a $C^\ast$-algebra. The relations between our approach and several other approaches to compact quantum groups are discussed.Comment: 14 pp., Plain TeX, accepted by Lett. Math. Phy

ELECTRON-MICROSCOPIC ANALYSIS AND BIOCHEMICAL-CHARACTERIZATION OF A NOVEL METHANOL DEHYDROGENASE FROM THE THERMOTOLERANT BACILLUS-SP C1

Methanol dehydrogenase from the thermotolerant Bacillus sp. C1 was studied by electron microscopy and image processing. Two main projections can be distinguished: one exhibits 5-fold symmetry and has a diameter of 15 nm, the other is rectangular with sides of 15 and 9 nm. Subsequent image processing showed that the 5-fold view possesses mirror symmetry. The rectangular views can be divided into two separate classes, one of which has 2-fold rotational symmetry. It is concluded that methanol dehydrogenase is a decameric molecule, and a tentative model is presented. The estimated molecular weight is 430,000, based on a subunit molecular weight of 43,000. The enzyme contains one zinc and one to two magnesium ions per subunit. N-terminal amino acid sequence analysis revealed substantial similarity with alcohol dehydrogenases from Saccharomyces cerevisiae, Zymomonas mobilis, Clostridium acetobutylicum, and Escherichia coli, which contain iron or zinc but no magnesium. In view of the aberrant structural and kinetic properties, it is proposed to distinguish the enzyme from common alcohol dehydrogenases (EC 1.1.1.1) by using the name NAD-dependent methanol dehydrogenase
