A giant coronary sinus mimicking descending aorta
(ACTA CARDIOLOGICA, 2008)
A 58-year-old male patient was admitted to the emergency service with dyspnoea. The patient underwent several laboratory and imaging tests including echocardiography and a diagnosis of descending aortic aneurysm was ...
Comparison of myocardial performance index versus ratio of isovolumic contraction time/ejection time in left ventricular systolic dysfunction
(SPRINGER, 2007)
Myocardial performance index (MPI) has been regarded as an important parameter in the evaluation of ventricular systolic function in congestive heart failure. This study was designed to investigate the relationship between ...
Numerical investigation of fouling on cross-flow heat exchanger tubes with conjugated heat transfer approach
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Although fouling on heat exchanger tubes is extensively investigated, due to the lack of energy resources, the effects of fouling on heat exchangers is still an important area of study and gaining more and more attention ...
Coronary collateral circulation: Any effect on P-wave dispersion?
(SAGE PUBLICATIONS INC, 2008)
Coronary collateral circulation determines the severity of ischemic myocardial damage. Increased P-wave dispersion is an independent predictor for atrial fibrillation. Consistent evidence is little about the relation between ...
Shallow-water foraminiferal assemblages and microfacies of the Danian-Lutetian sequences in the Bolu region (Northwestern Turkey)
(PLEIADES PUBLISHING INC, 2005)
The Paleocene and Eocene sediments of Bolu region were studied with respect to benthic foraminiferal stratigraphy and microfacies. In general, the Paleocene and Maastrichtian successions have conform contacts except for a ...
The evolution of travertine masses in the Sivas area (Central Turkey) and their relationships to active tectonics
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2008)
Sicak Cermik, Delikkaya and Sarikaya are important travertine fields with active hot springs located 31 km west of Sivas. Based on their morphology, most of the travertines are classified as fissure-ridge travertines. ...
Distribution of N-acetyltransferase type 1 (NAT1) genotypes and alleles in a Turkish population
(SOC BRASIL GENETICA, 2004)
NAT1 is an intronless gene on chromosome 8p21.3 encoding a 290-amino-acid-long protein showing acetyltransferase activity. Some 26 alleles of NAT1 gene have been identified in human populations. In the present study we ...
On Lie ideals with generalized derivations
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2006)
Let R be a prime ring with characteristic different from 2, let U be a nonzero Lie ideal of R, and let f be a generalized derivation associated with d. We prove the following results: (i) If a is an element of R and [a, f ...
Estimation of heritability and repeatability of milk yield of Brown Swiss cattle reared in Ulas State Farm
(INDIAN COUNC AGRICULTURAL RES, 2006)

Effects of the shape properties of talc and quartz particles on the wettability based separation processes
(ELSEVIER SCIENCE BV, 2004)
Shape properties of talc and quartz particles ground by a laboratory size ball, rod, and autogenous mills were studied using scanning electron microscope (SEM). More than 100 particles were measured to do the shape analysis ...
