Transition to inertio-elastic turbulence in Taylor–Couette flow with shear-thinning and viscoelastic polymer solutions is investigated when the rotation rate of inner cylinder increased outer fixed. In two PEO elastic number $$E \in \left\{ 0.16 ; 0.30 \right\} $$ , first instability circular Couette appears as spirals propagating opposite directions along axis cylinders. Just above onset patte...

AIM The aim of this study was to compare the short and long axis approaches to ultrasound guided right internal jugular vein cannulation with respect to indicators of success. METHODS Patients undergoing cardiac surgery requiring central venous cannulation (99 patients) were randomised to undergo either long or short axis ultrasound guided cannulation of the right internal jugular vein by a s...

BACKGROUND: Of the electrocardiographic changes in chronic obstructive lung disease (COLD) patients, a shift of the P wave axis greater than 90 which is highly characteristic, is said to be due to hyperinflation and does not occur in interstitial lung disease. OBJECTIVE : To describe the electrocardiographic changes in chronic obstructive lung disease patients. METHODS: The electrical axis of t...

Thresholds and biases of human motion perception were determined for yaw rotation and sway (left-right) and surge (fore-aft) translation, independently and in combination. Stimuli were 1 Hz sinusoid in acceleration with a peak velocity of 14°/s or cm/s. Test stimuli were adjusted based on prior responses, whereas the distracting stimulus was constant. Seventeen human subjects between the ages o...

The heart develops from a linear tubular precursor, which loops to the right and undergoes terminal differentiation to form the multichambered heart. Heart looping is the earliest manifestation of left-right asymmetry and determines the eventual heart situs. The signalling processes that impart laterality to the unlooped heart tube and thus allow the developing organ to interpret the left-right...

Congenital heart defects with heterotaxia are associated with pregestational diabetes mellitus. To provide insight into the mechanisms underlying such diabetes-related heart defects, we examined the effects of high-glucose concentrations on formation of the left-right axis in mouse embryos. Expression of Pitx2, which plays a key role in left-right asymmetric morphogenesis and cardiac developmen...
