Background: Avian infectious bronchitis (IB) is an infectious viral disease of chickens. The effective protection of chickens against many different infectious bronchitis virus (IBV) variants is not achieved unless the circulating genotypes in the region are identified and the cross-protection of the potential of vaccines in use is assessed. Aims:In a monitoring program of IBVs, a new genotype ...

In Q1 2021, the revenues of regions’ consolidated budgets went up compared to 2020. The growth was ensured by federal budget fiscal transfers and an increase in own tax non-tax regional local budgets. According results H1 we can expect double-digit rates subjects Russian Federation, main trend structure public debt regions until end this year will be replacement commercial loans with ones.

Three novel halogenated organic compounds (HOCs) have been identified in the blubber of marine mammals from coastal New England with the molecular formulae C(9)H(3)N(2)Br(6)Cl, C(9)H(3)N(2)Br(7), and C(9)H(4)N(2)Br(5)Cl. They were identified using high and low resolution gas chromatography mass spectrometry (GCMS) and appear to be highly brominated analogues of Q1, a heptachlorinated HOC suspec...

For the nonconforming rotated Q1 element over a mildly distorted quadrilateral mesh, we propose a superconvergence property at the element center, the vertices and the midpoints of four edges. Numerics are presented to confirm this observation.

If ~q1, . . . , ~qm : Z → Z are polynomials with zero constant terms and E ⊂ Z has positive upper Banach density, then we show that the set E ∩ (E − ~q1(p− 1))∩ . . .∩(E−~qm(p−1)) is nonempty for some prime p. We also prove mean convergence for the associated averages along the prime numbers, conditional to analogous convergence results along the full integers. This generalizes earlier results ...

We give a complete characterization of the class of upward monotone generalized quantifiers Q1 and Q2 over countable domains that satisfy the scheme Q1x Q2y ! Q2y Q1x . This generalizes the characterization of such quantifiers over finite domains, according to which the scheme holds iff Q1 is 9 or Q2 is 8 (excluding trivial cases). Our result shows that in infinite domains, there are more gener...
