madrasas and madrasa education, in terms of both quantity and quality, attained a remarkable progress in ottoman classic period, and reached the height of its splendor with the establishing of fâtih’s sahn-i thimân madrasas(875 a.h) and sulaymâniyya madrasas (965 a.h.). undoubtedly, numerous factors and variables had a role in the occurrence of this historical and the educational- cultural phen...

i ntroduction: assessment of cellular cytotoxicity is a regular method for evaluating the biocompatibility of novel materials. in a recent study, 5% fluoride varnish (duraflur) has shown reasonable sealing ability and coverage of root canal walls when used as a sealer. the aim of the present study was to compare cytotoxicity of duraflur varnish with two popular commonly used root canal sealers ...

Sažetak Arterijska hipertenzija (AH) jedan je od najvažnijih sprečivih (preventabilnih) uzroka prijevremenog umiranja i jedan od najvećih javnozdrastvenih problema današnjice u svijetu. Prevalencija AH je veća nego ranije i kreće se oko 40% u odraslim populacijama europskih zemalja, dok je u Sjedinjenim Američkim Državama značajno niža. Prema rezultatima studije “Epidemiologija arterijske hiper...

Let X be a subset of an abelian group and a1, . . . , ah, a ′ 1 , . . . , a h a sequence of 2h elements of X such that a1 + · · ·+ah = a ′ 1 + · · ·+a h . The set X is a Sidon set of order h if, after renumbering, ai = a ′ i for i = 1, . . . , h. For k ≤ h, the set X is a generalized Sidon set of order (h, k), if, after renumbering, ai = a ′ i for i = 1, . . . , k. It is proved that if X is a g...

Let φ(x1, . . . , xh, y) = u1x1 + · · · + uhxh + vy be a linear form with nonzero integer coefficients u1, . . . , uh, v. Let A = (A1, . . . , Ah) be an h-tuple of finite sets of integers and let B be an infinite set of integers. Define the representation function associated to the form φ and the sets A and B as follows: R (φ) A,B (n) = card ({(a1, . . . , ah, b) ∈ A1 × · · · × Ah × B : φ(a1, ....

The effects of acetone +/- spermine on the high (AH-I) and low (AH-II) affinity forms of aniline hydroxylases in the mouse hepatic microsomes were investigated under in vitro conditions. The addition of either acetone or spermine alone stimulated both AH-I and AH-II activities at low concentration while some decline in stimulation was noted at higher concentrations. In the presence of both the ...
