We prove that for every k > 1, there exist k-fold coverings of the plane (1) with strips, (2) with axis-parallel rectangles, and (3) with homothets of any fixed concave quadrilateral, that cannot be decomposed into two coverings. We also construct, for every k > 1, a set of points P and a family of disks D in the plane, each containing at least k elements of P , such that no matter how we color...

We prove that any cycle Cn, n ≥ 4, with list assignment L, has a k -fold list coloring from the given lists if (i) each list contains at least 2k colors and (ii) Cn and L satisfy Hall’s condition for k -fold list colorings. Further, 2k in (i) cannot be replaced by 2k − 1 if either n is odd, or n is even and n ≥ k + 2. In other words, if n ≥ 4, the k -fold Hall number of a cycle Cn satifies h (C...

In this paper we prove that the 3-fold injective tensor product ℓ1⊗ˆεℓ1⊗ˆεℓ1 is not isomorphic to any subspace of ℓ1⊗ˆεℓ1. This result provides a new solution problem Diestel on projective products c0. Moreover, implies for infinite countable compact metric space K, C(K)⊗ˆπC(K)⊗ˆπC(K) quotient C(K)⊗ˆπC(K).

Dalam proses penetuan mutu atau tingkat kemanisan buah alpukat di pasaran pada umumnya dilakukan dengan dua cara yaitu menggunakan pakar-pakar untuk pemilihan / sortasi metode destruktif pengambilan sampel, uji coba tersebut seperti Refractometer. Permasalahan yang terjadi kedua memiliki cost relatif besar dan tidak menghasilkan seragam karena oleh pakar bersifat subjektif kemungkinan terjadiny...

Objective(s): To evaluate the in vitro interaction between different extracts of Thymbra spicata L. and certain antimicrobial drugs of different mechanisms, including ampicillin, cefotaxime, amikacin and ciprofloxacin. This study was performed against multidrug-resistant strains of Staphylococcus aureus and Klebsiella pneumoniae. Materials and Methods: Evaluation of antibacterial activity and ...
