Abstract Introduction: With increasing survival of children with HLHS and other single ventricle lesions, the complexity of medical care for these patients is substantial. Establishing and adhering to best practice models may improve outcome, but requires careful coordination and monitoring.
Methods: In 2013 our Heart Center began a process to build a comprehensive Single Ventricle Team designed to target these difficult issues.
Results: Comprehensive Single Ventricle Team in 2014 was begun, to standardize care for children with single ventricle heart defects from diagnosis to adulthood within our institution. The team is a multidisciplinary group of providers committed to improving outcomes and… More >

Abstract Objective: Parents of infants with congenital heart disease (CHD) experience increased parenting stress levels, potentially interfering with parenting practices and bear adverse family outcomes. Condition severity has been linked to parenting stress. The current study aimed to explore parenting stress trajectories over infancy in parents of infants with complex CHD, and to compare them by post‐operative cardiac physiology.
Design: Data from a larger prospective cohort study was analyzed using longitudinal mixed‐effects regression modeling.
Setting: Cardiac intensive care unit and outpatient clinic of a 480‐bed children's hospital in the American North‐Atlantic region.
Participants: Parents of infants with complex CHD (n =… More >

Abstract Objective: Children with single ventricle cardiac disease (SVCD) have poor growth in early life. Tube‐assisted feeding (TF) is used to improve weight gain, but its impact on long‐term growth remains unknown. We sought to compare the longitudinal growth of SVCD patients receiving TF after initial cardiac surgery with those fed entirely by mouth.
Design: We conducted a retrospective cohort study of SVCD patients who under‐ went initial surgical palliation between 1999 and 2009. We defined TF as the use of nasogastric, gastrostomy, or jejunostomy TF. We compared maximal attained growth z‐scores for each year of life between TF and non‐TF… More >

Abstract This paper looked at the leaf architecture characteristics of Vachellia tortilis to determine if either there is or not an effect of the tropic line on plants. Vachellia tortilis leaves were sampled along a national road (N1) in Limpopo province. Sampling points were set 10 km apart away from the Tropic of Capricon in opposite directions. Leaf morphology revealed that leaves of V. tortilis are bipinnately compound with alternate arrangement. The venation pattern of the pinnules was eucamptodromus and brochidodromous with imperfect reticulation. Areoles were imperfect and pentagonal or irregular in shape. More >

Abstract An attempt is made into the investigation of longitudinal axisymmetric wave propagation in the DWCNT with the use of the exact equations of motion of the linear theory of elastodynamics. The DWCNT is modeled as concentricallynested two circular hollow cylinders between which there is free space. The difference in the radial displacements of these cylinders is coupled with the van der Waals forces and it is assumed that full slipping conditions occur on the inner surface of the outer tube and on the outer surface of the inner tube. Numerical results on the influence of the problem parameters such as… More >

Abstract In this paper, an accurate series solution for the longitudinal vibration analysis of elastically coupled nanorods system is established, in which artificial springs are introduced to simulate such general coupling and boundary conditions. Energy formulation is derived for the description of axial dynamics of multiple coupled nanorods based on Eringen nonlocal elasticity. For each nanorod component, its longitudinal vibration displacement function is invariantly assumed as the superposition of Fourier series and boundary smoothed supplementary polynomials, with the aim to make all the spatial differential sufficiently continuous across each rod. All the unknown coefficients are determined in conjunction with Rayleigh-Ritz procedure… More >

Abstract It is well known that blood vessels shorten axially when excised. This is due to the perivascular tethering constraint by side branches and the existence of pre-stretch of blood vessels at the \textit {in situ} state. Furthermore, vessels are radially constrained to various extents by the surrounding tissues at physiological loading. Our hypothesis is that the axial pre-stretch and radial constraint by the surrounding tissue homogenizes the stress and strain distributions in the vessel wall. A finite element analysis of porcine coronary artery and rabbit thoracic aorta based on measured material properties, geometry, residual strain and physiological loading is used… More >

Abstract In supersonic flow the leading edge vortex of delta wings can encounter intersection by an oblique or a normal shock. The resulting interaction between the two influences the aerodynamic forces, in particular the lift, especially if vortex breakdown occurs. This problem was studied in an idealized form by assuming an isolated slender vortex being intersected by an oblique and a normal shock, respectively. The investigation was carried out in two coordinated companion studies, one using numerical solutions of the Euler and Navier-Stokes equations, and the other experimental techniques, i. e. flow visualization methods, and Laser-Doppler and particle-image velocimetry. The measurements… More >

Abstract The conjugate gradient method (CGM) is applied in an inverse fin design problem in estimating the optimum shapes for the non-Fourier spine and longitudinal fins based on the desired fin efficiency and fin volume at the specified time. One of the advantages in using CGM in the inverse design problem lies in that it can handle problems having a huge number of design parameters easily and converges very fast.
The validity of using CGM in solving the present inverse design problem is justified by performing the numerical experiments. Several test cases involving different design fin efficiency, design fin volume, specified… More >
