12 neonates underwent arterial switch operation. In 3 patients palliative procedure was performed (1 pulmonary banding and 2 Blalock-Taussig shunts). Median weight at operation was 2400 g (2070-2500 g).\n\nResults: One death after arterial switch operation and one death after pulmonary banding were observed in early postoperative period. Postoperative morbidity occurred in 75% of patients, mainly: bleeding, pneumonia and neurological deficiencies. Mild or moderate pulmonary stenosis were postoperatively observed in 2 patients. No neonates required reoperation nor invasive
learn more cardiological intervention.\n\nConclusions: Low birth weight does not influence the survival of neonatetes with anatomically corrected transposition https://www.selleckchem.com/products/jph203.html of the great arteries.”
“Capture and quantitative analysis of the motion of organisms is a powerful tool that can be used in diverse
biological. fields including physiology, behavior, kinematics, and ecology. A number of high-end commercial motion capture and analysis systems that offer a wide array of features and image capture and analysis capabilities are available. However, few, if any, such systems are low cost and could be used for projects with small budgets or by researchers interested in collecting pilot data before upgrading to an expensive motion capture and analysis system. Our paper describes a low-cost (<$US1000, not including the cost of the computer) motion capture and analysis system that simultaneously captures live video from 5 digital video cameras (Unibrain Fire-i FireWire [IEEE 1394]) using standard security camera software (SecuritySpy 1.3.1). The video analyses are carried out using a combination of MDV3100 standard spreadsheet software (Microsoft Excel) and a freeware image-analysis program (NIH Image J), with one of the available particle-tracking plugins. Tests using New Zealand mudsnails (Potamopyrgus antipodarum) demonstrated that the system could record and accurately track the movement of small (4 mm) targets. Recommendations
for designing similar project-specific systems are provided.”
“In this paper, a coupled finite-hierarchic infinite element procedure is presented for an inhomogeneous transversely isotropic soil layer under irregularly distributed strip load. Elasticity and shear moduli follow a power law variation with depth. Quadratic quadrangular finite elements are coupled with a coordinate ascent hierarchic infinite element along the bounded edge using a least square approximation. The element mesh is fixed. Convergence is reached by increasing the polynomial degree. Novel results are presented for the vertital displacement and normal stress induced by uniform, parabolic, and triangular strip loads. The method is found to converge rapidly when the polynomial degree is increased.
