It is known that the Sylow subgroups of a Frobenius complement are cyclic or generalized quaternion. In this paper it is shown that there are no restrictions at all on the structure of the Sylow subgroups of the FrobeniusWielandt complements that appear in the well-known Wielandt's generalization of Frobenius' Theorem. Some examples of explicit constructions are also given. 0. Introduction Let ...

The present study reports an efficient protocol for isolation and regeneration of protoplasts from callus of Fritillaria imperialis L. There is no published method recommended for protoplast isolation and regeneration from Fritillaria imperialis L. A range of factors, which influence the success of isolation and regeneration of F. imperialis protoplasts, were investigated. From the results obta...

The utilization of creatine phosphate (CP) and adenosine triphosphate (ATP) was studied in the iodoacetate (IAA) and nitrogen (N(2))-treated cat papillary muscle. Under these conditions the net production of ATP does not occur, and the net utilization of ATP is reflected in a fall in CP concentration. The rate of energy utilization of the IAA-N(2)-treated cat papillary muscle resting without te...

Ginsburg and Sands defined a procedure for completely disconnecting graphs: each round, remove at most one edge from each component and at most w edges total. Define fw(g) to be the minimal number of rounds to reduce G to isolated vertices. Prior work of Ginsburg and Sands has determined fw(Pn) for 2 ≤ w ≤ ∞ and the lead-term asymptotics of f∞(Kn) and f2(Kn)). We show that when T is a tree with...

This study aimed to investigate the adsorption of three commercial reactive dyes using extracellular polymeric substances (EPS) extracted from waste sludge a beer wastewater treatment plant in Hanoi, Vietnam. EPS was by HCHO-NaOH method and characterized measuring kaolin flocculation activity, dry weight, chemical composition, functional groups. Adsorption on conducted Jartest at different pH v...

introduction: hydrocolloids are widely used in food systems as an emulsifying or stabilizing agent. one way to improve the emulsifying properties of hydrocolloids is complexation with proteins. in general, protein and hydrocolloid components may be combined together by either a) covalent bonding (conjugates) or b) electrostatic complexing. conjugates can be efficiently prepared during the stora...

The present study was undertaken to assess the effect of different chemical activators along with 6-DMAP on in vitro matured caprine oocytes. From 4332 ovaries, 14235 cumulus oocyte complexes (COCs) were collected which were matured in TCM-199 medium containing follicle stimulating hormone (FSH) (5 µg/ml), Leutinizing hormone (LH) (10 µg/ml), oestradiol-17β (1 µg/ml) supplemented with 10% fetal...

In this study, ZnFe2O4 and ZnO-ZnFe2O4 catalysts were prepared using the glycine–nitrate process (GNP). The catalyst powders characterized a scanning electron microscope, transmission XRD diffraction studies, selected area pattern studies. addition, specific surface was measured Brunauer–Emmett–Teller analysis. hydrogen reduction in different temperature ranges analyzed H2 temperature-programme...

Bioprotection de Cucumis melo contre maladie des taches foliaires par Glomus mosseae et Trichoderma harzianum. Alternaria alternata, responsable l’alternariose foliaires, est une propagation mondiale notamment en Irak. Cette se caractérise la formation lésions sur les feuilles, entraînant pertes substantielles rendement qualité chez plusieurs espèces végétales telles que (melon). harzianum sont...

introduction: dill (anethum graveolens), a herb from from umbelliferae, is used traditionally to treat convulsion and increasing milk production. its antimicrobial, antihyperlipidaemic, anti-hypercholesteroaemic effects and gastric acid secretion reducing effect have been reported. the spasmolytic effect of dill fruit on rat uterus has also been shown recently. the aim of present study was to i...
