results there were significant differences between the groups in subjective labor pain scores (except vas 4) (p < 0.001). the duration of the phase one (3 cm dilatation to full dilatation) and phase two (full dilatation to birth) in the acupressure group was shorter than the control group (phase one, 225 min and 320 min, respectively; phase two, 15 min and 20 min, respectively; both p < 0.001)....

We introduce the concept of $k$-(semi)-dilation for Liouville domains, which is a generalization symplectic dilation defined by Seidel-Solomon. prove that existence property independent fillings asymptotically dynamically convex (ADC) manifolds. construct examples with $k$-dilations, but not $k-1$-dilations all $k\ge 0$. extract invariants taking value in $\mathbb{N} \cup \{\infty\}$ domains an...

foam injection is becoming a standard conditioning agent when tunnelling with an earth-pressure balanced shield, resulting in an increasing interest in this technique. the technique is mostly based on empirical rules and experience. to be able to determine what foam and how may foam has to be injected for different soils, it is necessary to know the mechanical parameters of the foam-water-soil ...

The purpose of this study was to test the hypothesis that endothelium-dependent dilation (flow-induced dilation and ACh-induced dilation) in rat soleus muscle arterioles is impaired by hindlimb unweighting (HLU). Male Sprague-Dawley rats (approximately 300 g) were exposed to HLU or weight-bearing control (Con) conditions for 14 days. Soleus first-order (1A) and second-order (2A) arterioles were...

BACKGROUND Percutaneous balloon pulmonary valvuloplasty (PBPV) is the preferred therapy for pulmonary valve stenosis (PVS). This study retrospectively reviewed recent PBPV outcomes in infants with PVS. The aim of this study was to evaluate factors associated with immediate therapeutic outcomes and restenosis during medium-term follow-up. METHODS The study included 158 infants with PVS who und...
