Let V be a 2m-dimensional vector space over a field F (m ≥ 2) and let k ∈ {1, . . . , 2m − 1}. Let A2m−1,k denote the Grassmannian of the (k − 1)-dimensional subspaces of PG(V ) and let egr denote the Grassmann embedding of A2m−1,k into PG( ∧k V ). Let S be a regular spread of PG(V ) and let XS denote the set of all (k − 1)-dimensional subspaces of PG(V ) which contain at least one line of S. T...

In this paper, we introduce $(p,q)g-$Bessel multipliers in Banach spaces and we show that under some conditions a $(p,q)g-$Bessel multiplier is invertible. Also, we show the continuous dependency of $(p,q)g-$Bessel multipliers on their parameters.

This study aimed to improve delivery of lomustine as a chemotherapeutic agent and to increase its uptake by U87-MG cancer cells via synthesizes LN-FA-PG-SPIONs (lomustine loaded polyglycerol coated superparamagnetic iron oxide nanoparticles conjugated with folic acid). Nanoparticles were synthesized by thermal decomposition method and characterized using TEM (transmission microscope), FTIR (Fou...

Let and B̄ be a subset of = PG(2n − 1, q) and a subset of PG(2n, q) respectively, with ⊂ PG(2n, q) and B̄ ⊂ . Denote by K the cone of vertex and base B̄ and consider the point set B defined by B = (K\ ) ∪ {X ∈ S : X ∩ K = ∅}, in the André, Bruck-Bose representation of PG(2, qn) in PG(2n, q) associated to a regular spread S of PG(2n − 1, q). We are interested in finding conditions on B̄ and in order...

A full classification (up to equivalence) of all complete k-arcs in the Desarguesian projective planes of order 27 and 29 was obtained by computer. The resulting numbers of complete arcs are tabulated according to size of the arc and type of the automorphism group, and also according to the type of algebraic curve into which they can be embedded. For the arcs with the larger automorphism groups...

Two high galactic latitude B-type stars, PG 1323−086 and PG 1704+222, are analysed from low and medium resolution optical spectra and Strömgren photometry. A differential abundance analysis for He, C, N, O, Mg, Al, and Si reveals that the He abundance is close to solar while metal underabundances relative to the solar value of typically 1.3 and 1.2 dex for PG 1323−086 and PG 1704+222, respectiv...

An (n, r)-arc is a set of n points of a projective plane such that some r, but no r + 1 of them, are collinear. In this paper new (95, 7)-arc, (183, 12)-arc, (205, 13)-arc in PG(2,17) and (243, 14)-arc, (264, 15)-arc in PG(2,19) are constructed.

The entanglement-assisted (EA) formalism is a generalization of the standard stabilizer formalism, and it can transform classical linear quaternary codes into entanglement-assisted quantum error correcting codes (EAQECCs) by using of shared entangled qubits between the sender and the receiver. In this work, we give elementary recursive constructions of special quaternary codes of length n and d...

conclusions bacteria from biological waste were competent producers of pg and must be used on an industrial scale to cope with the demand of pg in the food industry. results among the bacillus, bacillus vallismortis (jq990307) isolated from mango was the most competent producer of pg; producing up to 4.4 u/µl. amongst pseudomonas, pseudomonas aeruginosa (jq990314) isolated from oranges was the ...
