A multivariable control scheme is designed to minimize emission of nitrogen oxides NOx and generation of smoke in a Diesel engine equipped with a variable geometry tur bocharger VGT and an external exhaust gas recirculation system EGR Steady state optimization results in operat ing points where NOx emissions and smoke generation are highly coupled and require joint management by VGT and EGR act...

Türkiye’nin Güney Doğu Anadolu Bölgesi’nde, Mardin’in kuzey doğusunda Midyat merkezli dağlık bir alan olan, tarihsel ve dini açılardan taşıdığı değer nedeniyle Süryaniler tarafından adeta kutsal bölge olarak görülen “Tur Abdin”, manastırlarıyla meşhur coğrafyadır. Söz konusu manastırlara ya da bölgedeki monastik yaşamın başlangıcına dair anlatılarda IV. yüzyılda yaşadığı tahmin edilen Mor Evgin...

OBJECTIVE To evaluate the effects of two different spinal isobaric levobupivacaine doses on spinal anesthesia characteristics and to find the minimum effective dose for surgery in patients undergoing transurethral resection (TUR) surgery. MATERIALS AND METHODS Fifty male patients undergoing TUR surgery were included in the study and were randomized into two equal groups: Group LB10 (n=25): 10...

OBJECTIVE To evaluate the efficacy of narrow band imaging (NBI) cystoscopy associated with bipolar plasma vaporization (BPV) in cases of large nonmuscle-invasive bladder tumors (NMIBTs) compared with white light cystoscopy (WLC) and monopolar transurethral resection of bladder tumors (TURBTs). METHODS A total of 220 cases with ≥ 1 bladder tumor >3 cm determined by abdominal ultrasonography, c...

OBJECTIVE To compare the effectiveness and safety of two minimally invasive methods (transrectal aspiration vs transurethral resection (TUR)/deroofing) of treating prostatic abscess. PATIENTS AND METHODS A retrospective study was conducted, from 2007 to 2016, of patients with prostatic abscesses not responding to antibiotics and/or with large (>2 cm) or multiple abscesses. Patients were divid...

The present work has studied mechanisms responsible for induction of early growth response 1 (EGR-1) gene expression during monocytic differentiation of U-937 myeloid leukemia cells. Differentiation of U-937 cells with 12-O-tetradecanoylphorbol-13-acetate (TPA), an activator of the serine/threonine protein kinase C, was associated with transcriptional activation of EGR-1 promoter-reporter const...

Let $P(G,lambda)$ be the chromatic polynomial of a graph $G$. A graph $G$ ischromatically unique if for any graph $H$, $P(H, lambda) = P(G,lambda)$ implies $H$ is isomorphic to $G$. In this paper, we determine the chromaticity of all Tur'{a}n graphs with at most three edges deleted. As a by product, we found many families of chromatically unique graphs and chromatic equivalence classes of graph...
