Theoretical study on the ground state intramolecular proton transfer (IPT) and solvation effect in two Schiff bases formed by 2-aminopyridine with 2-hydroxy-1-naphthaldehyde and 2-hydroxy salicylaldehyde
(SPRINGER, 2009)
The tautomerization mechanism the isolated and monohydrated forms of two Schiff bases 1 and 2, and the effect of solvation on the proton transfer from enol-imine form to the keto-enamine form have been investigated using ...
Effect of L-NAME on decreased ileal muscle contractility induced by peritonitis in rats
(W B SAUNDERS CO, 2002)
Background/Purpose: It is now well established that intestinal inflammation is associated with disturbed contractility. The aim of this study was to determine the effects of peritonitis on longitudinal ileum smooth muscle ...
The effect of BOD5 and flow-rate of activated sludge systems on investment and energy costs
(INDERSCIENCE ENTERPRISES LTD, 2005)
In this study of wastewater treatment, the effect of flow-rate, BOD5 and other design parameters (MLSS, mean cell-residence time, etc.) on aeration tank dimensions, investment amount and energy cost has been investigated. ...
A morphometric and histopathologic evaluation of the effects of propolis on alveolar bone loss in experimental periodontitis in rats
(AMER ACAD PERIODONTOLOGY, 2008)
Background: Propolis collected by honeybees from various plant sources is a resinous hive product possessing a broad spectrum of biologic activities. Propolis has been used extensively in the diet to improve health and ...
Late cenozoic stress evolution along the Karasu Valley, SE Turkey
(ELSEVIER SCIENCE BV, 2004)
This study defines the Mio-Pliocene to present-day stress regime acting at the northeastern comer of the eastern Mediterranean region along the Karasu Valley (i.e., the Amanos Range), taking in the Antakya, Osmaniye and ...
Explosive-based anchoring system in cable bolts
(MANEY PUBLISHING, 2003)
This study deals with research work based on a new explosive-based anchorage system for cable bolts. The aim of this system is to apply pre-tension to cable bolts, which is independent of cement mortar. Within the scope ...
Effect of hypothyroidism on the purinergic responses of corpus cavernosal smooth muscle in rabbits
(SPRINGER, 2008)
Aims Several studies have reported evidence of hormonal abnormalities in 25-35% of impotent men. Hypothyroidism has been reported to occur in 6% of impotent men. In the present study, we examined purinergic relaxation ...
Cu(II) removal from aqueous solution using Dogantepe (Amasya) zeolites
(INDERSCIENCE ENTERPRISES LTD, 2003)
This paper investigates the effects of zeolite particle size, zeolite/solution ratio and stirring time on the performance of zeolites from Dogantepe in removing Cu(II) from aqueous solution to establish optimum operating ...
Human microphthalmia associated with mutations in the retinal homeobox gene CHX10
(NATURE PUBLISHING GROUP, 2000)
Isolated human microphthalmia/anophthalmia, a cause of congenital blindness, is a clinically and genetically heterogeneous developmental disorder characterized by a small eye and other ocular abnormalities. Three ...
Large-eddy simulation of the flow in a low-speed centrifugal compressor
(JOHN WILEY & SONS LTD, 2008)
The results of a series of numerical simulations for the NASA low-speed centrifugal compressor are presented. Large-eddy simulation (LES) is carried out together with the most commonly used Reynolds-averaged Navier-Stokes ...
