Abstract The recent observation of 4 He favors a large lepton asymmetry at the big bang nucleosynthesis. If Q-balls with charge decay after electroweak phase transition, such can be generated without producing too baryon asymmetry. In this scenario, dominate universe before and induces sharp transition from early matter-dominated era to radiation-dominated era. gravitational waves (GWs) are enh...

Background & Aim: Q fever is an important zoonotic disease caused by infection with Coxiella burnetii, a Gram negative, obligate intracellular bacterium classified within the order Legionellales. Farmers, veterinarians, abattoir workers and laboratory personnel are among persons at risk of Q fever. The aim of this study was to determine frequency of IgM anti-Coxiella burnetii antibodies in slau...

A classification is given of all spreads in PGð3; qÞ, q 1⁄4 2 , whose associated translation planes admit linear collineation groups of order qðqþ 1Þ.

‎in this paper‎, ‎we give some necessary conditions for a complex‎ ‎difference equation of malmquist type‎ $$‎sum^n_{j=1}f(z+c_j)=frac{p(f(z))}{q(f(z))}‎,$$ ‎where $n(in{mathbb{n}})geq{2}$‎, ‎and $p(f(z))$ and $q(f(z))$ are‎ ‎relatively prime polynomials in $f(z)$ with small functions as‎ ‎coefficients‎, ‎admitting a meromorphic function of finite order‎. ‎moreover‎, ‎the properties of finite o...

A classification is given of all spreads in PG(3,#), q = 2, whose associated translation planes admit linear collineation groups of order q(q -hi) .
