OBJECTIVES The objectives of this study were to present and explore the clinical presentation of the increasingly common pediatric exposure to the widely available single-use laundry packets or "laundry pods." METHODS This is a case report of 4 pediatric patients with significant toxicity due to laundry pod detergent exposure and a review of the available literature including abstract-only pu...

BACKGROUND Postoperative hypoparathyroidism remains the most common complication following thyroidectomy. The aim of this pilot study was to evaluate the use of intraoperative parathyroid gland angiography in predicting normal parathyroid gland function after thyroid surgery. METHODS Angiography with the fluorescent dye indocyanine green (ICG) was performed in patients undergoing total thyroi...

Determining when a numerical simulation is fully converged is important in getting accurate and reliable results. In this study a new convergence criterion based on extracting the energetic modes of a numerical solution, based on the Proper Orthogonal Decomposition method, is suggested. The POD convergence criterion is tested and applied to flow over a bluff body which has been solved numerical...

The “equation-free” (EF) method is based on a procedure, which is often used in complex, multi-scale problems, given an initial macroscopic variable, by lifting, evolve in Direct Numerical Simulations (DNS), restriction, and projective integration. In this paper, we apply the Equation-free method to the reduced modeling of a large-scale upper ocean circulation in the tropic Pacific domain. We c...

Despite the temporal and spatial complexity of common fluid flows, model dimensionality can often be greatly reduced while both capturing and illuminating the nonlinear dynamics of the flow. This work follows the methodology of direct numerical simulation !DNS" followed by proper orthogonal decomposition !POD" of temporally sampled DNS data to derive temporal and spatial eigenfunctions. The DNS...

A dual-plane snapshot POD analysis of turbulent pipe flow at a Reynolds number of 104,000 is presented. The high-speed PIV data were simultaneously acquired in two planes, a crossstream plane (2D-3C) and a streamwise plane (2D-2C) on the pipe centerline. The cross-stream plane analysis revealed large structures with a spatio-temporal extent of 1-2R, where R is the pipe radius. The temporal evol...

A study is presented on power oscillation damping control (POD) using wide area measurements applied to a single static var compensator (SVC). An equivalent power system model representing key characteristics of the Nordic power system is used. Feedback signals from remote phasor measurment units (PMUs) in Norway and Finland are used to damp the critical inter-area modes through a large SVC uni...

The need to establish power plants to supply the required electricity of the country has been rising due to increasing demand levels as well as the lack of governmental resources. Furthermore, the available traditional attitude in performing and conducting power plant projects has made government seek a modern attitude. This paper tries to use the topics that have been employed in automotive in...

This study was conducted on two canola (Brassica napus) cultivars, Okapi a winter type and cold tolerant and Rgs003 a spring type and cold sensitive. Seedlings were grown in an environmentally controlled growth room with 16 h d-1 photoperiod at 22/16 °C (day/night, control). At the 4-leaf stage, half of pots were transferred to a cold growth room for 7 d at 10/3°C (day/night, cold treatment) an...

In this paper we derive a reduced-order approximation to the vertical and horizontal structure of a simplified model of the baroclinically unstable Martian atmosphere. The original model uses the full hydrostatic primitive equations on a sphere, but has only highly simplified schemes to represent the detailed physics of the Martian atmosphere, e.g. forcing towards a plausible zonal mean tempera...
