Populations of the Caribbean lizard, Anolis roquet, are thought to have experienced long periods of allopatry before recent secondary contact. To elucidate the effects of past allopatry on population divergence in A. roquet, we surveyed parallel transects across a secondary contact zone in northeastern Martinique. We used diagnostic molecular mitochondrial DNA markers to test fine-scale associa...

In this study the pressure-drop, mean and rms axial velocity data are measured using a differential pressure transducer and a laser Doppler anemometer for the flow of Newtonian and non-Newtonian fluids in a concentric annular pipe (radius ratio =0.5) at various Reynolds numbers encompassing the laminar, transitional and turbulent regimes. Three different fluids are utilized; a semi-rigid shear-...

micropapillary variant of urothelial carcinoma (uc) of the bladder is an aggressive tumour, comprising 0.6-6% of all uc. it generally presents with high-grade and stage, and has been reported as having a worse prognosis when compared to traditional uc. we report the case of a 58-year-old man who presented with macroscopic haematuria. the patient was diagnosed with high-grade urothelial carcinom...

Transitional cell carcinoma(T.C.C) of bladder display an upredictable biological behavior.Morphologic methods of grading this tumor are insuficient to predict the clinical outcome of the patients.the aim of this study was to investigate the relationships between histological grading staging and DAN ploidy especially in intermediate grade II(IIa and IIb). in a retrospective study  of tissue spec...

Using the recent DNS by Wu and Moin (2010) of a flat-plate boundary layer with a passively heated wall, statistics of the turbulence in transition at Reθ = 500 where spots merge (distributions of the mean velocity, rms velocity and vorticity component fluctuations, kinetic energy production and dissipation rates and enstrophy) have been compared to these statistics for the developed boundary la...
