Transfer of patients from the cardiac intensive care unit to the general ward, is one of the main reasons for anxiety. Given that the transfer anxiety may be due to receive at least, inconsistent or do not receive enough information before the patients leaving the intensive care unit, Therefore, this study aimed to determine the effect of information provision on anxiety levels in patients tran...

We recall that Theorem 1.3 allows us to define the ideal class group of a Dedekind domain, and in particular of a ring of integers, as the group of fractional ideals modulo the subgroup of principal ideals. We will prove that in the case of a ring of integers, the ideal class group is finite. In fact, we will shortly give a stronger statement due to Minkowski. Using similar techniques, we will ...

While the unit group of an imaginary quadratic field is very simple, the unit group of a real quadratic field has nontrivial structure. Its study involves some geometry and analysis, but also it relates to Pell's equation and continued fractions, topics from elementary number theory.

It is our purpose to study curvature structures of compact hypersurfaces in the unit sphere S(1). We proved that the Riemannian product S( √ 1 − c2) ×Sn−1(c) is the only compact hypersurfaces in S(1) with infinite fundamental group, which satisfy r ≥ n−2 n−1 and S ≤ (n − 1)n(r−1)+2 n−2 + n−2 n(r−1)+2 , where n(n − 1)r is the scalar curvature of hypersurfaces and c = n−2 nr . In particular, we o...

Background: Cataracts are the leading diseases that cause blindness. Cataracts can be treated with surgery. Pain, itching, burning, and a foreign body sensation in the eye are common ocular complaints of patients in recovery. In this study, we compared the effect of Ketorolac eye drops and naphazoline antazoline eye drops on reducing complaints of surgery. Methods: This randomized clinical tri...
