Levosimendan improves renal function in patients with acute decompensated heart failure: Comparison with dobutamine
(SPRINGER, 2007)
Background Levosimendan is a relatively new cardiac inotropic agent with calcium sensitizing activity. This study was conducted to investigate the effects of levosimendan (L) and dobutamine (D) on renal function in patients ...
Bond strength of a silicone soft lining material to poly(methyl methacrylate) resin treated with maleic anhydride and its terpolymers
(TAYLOR & FRANCIS LTD, 2007)
This study investigated the effectiveness of surface treatment of Poly (methyl methacrylate) (PMMA) denture base resin on tensile bond strength between PMMA/silicone-based soft liner. A total of 25 specimens were fabricated ...
The polarizability and the photoionization cross-section under the external fields for donor impurities in quantum well-wire
(WILEY-V C H VERLAG GMBH, 2007)
In this study, we have calculated the donor impurity binding energy, donor impurity related photoionization cross-section and polarizability in symmetric GaAs/Ga1-xAlxAs quantum well-wire as a function of the impurity ...
Interband absorption and exciton binding energy in an inverse parabolic quantum well under the magnetic field
(ELSEVIER SCIENCE BV, 2007)
We have investigated the effects of the magnetic field which is applied perpendicular to the growth direction of the well on the interband absorption and on the binding energy of the excitons in an GaAs/Ga1-xAlxAs inverse ...
Floatability of barite particles with different shape and roughness
(NATL INST SCIENCE COMMUNICATION, 2007)
In this article, different mill (ball, FOCI and autogenous) products of barite mineral were characterized in terms of their shape., roughness and wettability. 2D shape parameters were measured by the particle projections ...
A new approach to predicting the carbonyl stretching frequencies of Co-2(CO)(8) with D-3d symmetry
(NATL INST SCIENCE COMMUNICATION, 2007)
This paper describes a method for determining C-O stretching frequencies of dicobalt octacarbonyl belonging to D-3d point group. The method is based on the variation of fundamental C-O stretching frequencies and C-O ...
Effects of gingival retraction materials on gingival blood flow
(QUINTESSENCE PUBLISHING CO INC, 2007)
Purpose: The effects of 2 chemical retraction agents on gingival blood flow and systemic blood pressure in subjects with healthy gingiva were investigated. Materials and Methods: Thirty volunteer dental students were ...
The recurrent aphthous stomatitis frequency in the smoking cessation people
(SPRINGER HEIDELBERG, 2007)
This study was aimed to evaluate the frequency of recurrent aphthous stomatitis ( RAS) within the 6-week period after quitting smoking. The study group consisted of 90 subjects. Oral, medical findings and tobacco habits ...
A rare variation of the right middle suprarenal artery
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2007)
According to general knowledge, the suprarenal. gland is supplied by three sources: the phrenic artery, the abdominal. aorta and the renal artery. Since the gland tacks a hilus, and particularly because of its clinical ...
Binding energy of impurity states in an inverse parabolic quantum well under magnetic field
(ELSEVIER SCIENCE BV, 2007)
We have investigated the effects of the magnetic field which is directed perpendicular to the well on the binding energy of the hydrogenic impurities in an inverse parabolic quantum well (IPQW) with different widths as ...
