We study the asymptotic behaviour of number solutions $$(m, n)\in \mathbb{N}^2$$ , to inequality $$| \alpha^n - \beta^m | \leq x$$ when x tends infinity. Here $$\alpha, \beta$$ are given multiplicatively independent complex numbers with $$|\alpha| > 1 {\rm and} |\beta|>1$$ .
In the present paper, we study normalized solutions with least energy to following system: $$\begin{aligned} {\left\{ \begin{array}{ll} -\Delta u+\lambda _1u=\mu _1 |u|^{p-2}u+\beta r_1|u|^{r_1-2}|v|^{r_2}u\quad &{}\hbox {in}~{{\mathbb {R}}^N},\\ v+\lambda _2v=\mu _2 |v|^{q-2}v+\beta r_2|u|^{r_1}|v|^{r_2-2}v\quad \int _{{{\mathbb {R}}^N}}u^2=a_1^2\quad \hbox {and}\quad {R}}^N}}v^2=a_2^2, \end{a...
In vivo demonstration of cardiac beta 2-adrenoreceptor sensitization by beta 1-antagonist treatment.
proper conditions for producing crude beta-galactosidase from waste materials were de-termined. this enzyme is to be used in the production of lactose-hydrolyzed milk. whey permeate was used as a basic medium. twenty seven treatments were developed by 3 vary-ing factors of: yeast extract (1, 2, and 3 %), wheat steep liquor (1, 2, and 3 %), and whey powder (0.5, 1, and 1.5 %). crude enzyme extra...
Background: Hb A2 is elevated in subjects with beta thalassemia minor but small percent of carriers have normal Hb A2 with elevated levels of HbF (2-10%). This type of thalassemia is called delta beta thalassemia, and can be missed in pre-marriage hematologic consults or screening which leads to increased risk of child birth with beta thalassemia major. Materials and Methods: In this prospe...
The beta0diketone derivatives of nitroimidazole were synthesized from the reaction of magnesium salt of beta-ketoaccids 3 with imidazolide 4. The raction of beta-diketones with hydroxylamine hydrochloride afforded either the isoxazoles or the 5-hydroxyl-2-isoxazolines.
