It is shown that there exists a positive c so that for any large integer m, any graph with 2m 2 edges contains a bipartite subgraph with at least m 2 + m/2 + c √ m edges. This is tight up to the constant c and settles a problem of Erd˝ os. It is also proved that any triangle-free graph with e > 1 edges contains a bipartite subgraph with at least e 2 + c e 4/5 edges for some absolute positive co...

The Research has shown that the primary sound source in centrifugal turbomachines is the blade passing frequency noise, which is caused by due to impac rotor exit flow with the volute and the wild pressure fluctuations. In this paper, a centrifugal blower with forward facing blades has been selected and the sound created by it in the output channel has been investigated in different operating c...

Human papillomavirus (HPV) DNA tests tend to show high sensitivity, but poor specificity in detecting high-grade cervical lesions. This study aimed to explore the clinical performance of QuantiVirus(®) HPV E6/E7 mRNA in identifying ≥Grade 2 cervical intraepithelial neoplasia. Thin-prep(®) liquid based cytology test (LBC) samples were collected from October 2009 to October 2011 from women who un...

Screening endoscopy is recommended for early detection of esophageal varices (EVs) in cirrhotic patients with portal hypertension. However, this approach is limited by its invasiveness and cost. The aim of the study was to determine if platelet count can predict the presence of EVs, especially large (grade III, IV) EVs in need of prophylactic therapy, in a cohort of Egyptian patients with liver...

Background: Assessment of AMH cut-off levels in serum and in follicle fluid (FF) for patients with (group 2, n=34) and without (group1, n= 96) endocrinological risk factors, such as ovarian hyperstimulation syndrome (OHSS) and polycystic ovary syndrome (PCOS), is clinically useful in optimising the treatment protocol. Materials and Methods: AMH was analysed in serum and FF of 130 infertile pati...

Accelerometers are becoming more widely used in the assessment of physical activity in children, and converting the output to min of moderate-to-vigorous physical activity (MVPA) requires the use of age-specific cut-off point definitions. However, numerous cut-off points are available among children, and different cutoff point definitions of MVPA have been used in different studies. Comparison ...

Positron emission tomography with 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG-PET) has been proven useful for differentiating pancreatic ductal cancer from mass-forming chronic pancreatitis. However, there are particular pancreatic tumors having various grades of malignancy such as intraductal papillary mucinous neoplasm (IPMN) or pancreatic neuroendocrine tumor. We examined whether the cut-off valu...

OBJECTIVE To determine if electrical impedance spectroscopy (EIS) improves the diagnostic accuracy of colposcopy when used as an adjunct. DESIGN Prospective, comparative, multi-centre clinical study. SETTING Three colposcopy clinics: two in England and one in Ireland. POPULATION Women referred with abnormal cytology. METHODS In phase 1, EIS was assessed against colposcopic impression an...

Power output (P), thermal efficiency (η) and ecological function (E) characteristics of an endoreversible Dual-Miller cycle (DMC) with finite speed of the piston and finite rate of heat transfer are investigated by applying finite time thermodynamic (FTT) theory. The parameter expressions of the non-dimensional power output (P), η and non-dimensional ecological function (E) are derived. The rel...
