let $r$ be a 2-torsion free ring and $u$ be a square closed lie ideal of $r$. suppose that $alpha, beta$ are automorphisms of $r$. an additive mapping $delta: r longrightarrow r$ is said to be a jordan left $(alpha,beta)$-derivation of $r$ if $delta(x^2)=alpha(x)delta(x)+beta(x)delta(x)$ holds for all $xin r$. in this paper it is established that if $r$ admits an additive mapping $g : rlongrigh...

BACKGROUND Inhaled beta-agonist therapy is central to the management of acute asthma. This review evaluates the benefit of an additional use of intravenous beta(2)-agonist agents. OBJECTIVES To determine the benefit of adding intravenous (IV) beta(2)-agonists to inhaled beta(2)-agonist therapy for acute asthma treated in the emergency department. SEARCH METHODS Randomised controlled trials ...

Beta-decay spectroscopy of the $^{187}\mathrm{Ta}$ ground state was performed at KEK Isotope Separation System. $\ensuremath{\beta}$-delayed $\ensuremath{\gamma}$ rays corresponding to previously reported in-beam transitions were observed. The $\ensuremath{\beta}$-decay half-life determined be 283(10) s by analyzing a time spectrum $\ensuremath{\beta}\text{\ensuremath{-}}\ensuremath{\gamma}$ co...
