A path-matching of order p is a vertex disjoint union nontrivial paths spanning vertices. Burr and Roberts, Faudree Schelp determined the 2-color Ramsey number path-matchings. In this paper we study multicolor Given positive integers r,p1,…,pr, define RPM(p1,…,pr) to be smallest integer n such that in any r-coloring edges Kn there exists color i at least pi for some i?[r]. Our main result r?2 p...

A interação planta-microrganismos é foco de pesquisas nas últimas décadas. Objetivou-se avaliar a eficiência agronômica do inoculante, contendo Bacillus megaterium e B. subitilis, para soja, via sementes, associado à adubação fosfatada. Conduziu-se quatro ensaios, outubro 2019 março 2020 em Palotina/PR, São Miguel Iguaçu/PR, Cascavel/PR Toledo/PR, com cultivar Piooner® 96y90. Em delineamento bl...

Two cobalt and two Nickel complexes of bis[N-(2,6-diisopropylphenyl)imino]acenaphthene (Pr-BIAN) ligand, have been synthesized. These complexes, namely [Co(Pr-BIAN)Cl2] 1, [Co(OAc)2 (Pr-BIAN)2](ClO4) 2, [Ni(Pr-BIAN)(NO3)2] 3 and [Ni(Pr-BIAN)2](ClO4)2 4, were characterized by elemental analyses, molar conductance, spectral (IR, UV-Visible and NMR) and magnetic moment measurements. In these compl...

Ordered and accurate processing of the human immunodeficiency virus type 1 (HIV-1) GagPol polyprotein precursor by a virally encoded protease is an indispensable step in the appropriate assembly of infectious viral particles. The HIV-1 protease (PR) is a 99-amino-acid enzyme that is translated as part of the GagPol precursor. Previously, we have demonstrated that the initial events in precursor...

Introduction of a number of HIV-1 protease (PR) inhibitors as anti-AIDS drugs has drastically changed the clinical prognosis for the outcome of this disease, from almost invariably lethal to chronic. This achievement also represented the first major success of structure-based drug design, encouraging the use of similar approaches to other major diseases, such as cancer. We have now identified a...

Let P = {p1, . . . , pr} ⊂ Q[n1, . . . , nm] be a family of polynomials such that pi(Z) ⊆ Z, i = 1, . . . , r. We say that the family P has the PSZ property if for any set E ⊆ Z with d∗(E) = lim supN−M→∞ |E∩[M,N−1]| N−M > 0 there exist infinitely many n ∈ Zm such that E contains a polynomial progression of the form {a, a + p1(n), . . . , a + pr(n)}. We prove that a polynomial family P = {p1, . ...

Relatively resource-rich but property inferior-Ce-Fe-B magnet can be improved by partial replacement of Ce Nd and/or Pr. In addition to the amount Nd/Pr, their distribution profile in microstructure plays an important role. From our first principles density functional theory (DFT) calculation, substitution energy Pr/Nd is negative <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink=...

PURPOSE Hormone receptor (HR) status is a prognostic factor in women with breast cancer and differs among different ethnic groups. HR status among Turkish, Kurdish and Arabic women with breast cancer living in Turkey is unknown and in this study we investigated the relationship between HR and HER2 status and race. METHODS FA total of 648 women with breast cancer (Turkish 438, Kurdish 174, Ara...
