Asymptotic and exact local radiation boundary conditions first derived by Hagstrom and Hariharan are reformulated as an auxiliary Cauchy problem for linear first-order systems of ordinary equations on the boundary for each harmonic on a circle or sphere in twoor three-dimensions, respectively. With this reformulation, the resulting radiation boundary condition involves first-order derivatives o...

Problems in unbounded domains are often solved numerically by truncating the infinite domain via an artificial boundary B and applying some boundary condition on B, which is called a Non-Reflecting Boundary Condition (NRBC). Recently, a two-parameter hierarchy of optimal local NRBCs of increasing order has been developed. The optimality is in the sense that the local NRBC best approximates the ...

OBJECTIVE Nucleated red blood cells (NRBCs) have been identified in maternal circulation and potentially provide a resource for the monitoring and diagnosis of maternal, fetal, and neonatal health and disease. Past strategies used to isolate and enrich for NRBCs are limited to complex approaches that result in low recovery and less than optimal cell purity. Here we report the development of a h...

The simultaneous partial nitrification, ANAMMOX and denitrification (SNAD) process was validated to potentially remove ammonium and COD from wastewater in a single, oxygen-limited, non-woven rotating biological contactor (NRBC) reactor. An ammonium conversion efficiency of 79%, TN removal efficiency of 70% and COD removal efficiency of 94% were obtained with the nitrogen and COD loading rate of...

A spectral element (SE) implementation of the Givoli–Neta non-reflecting boundary condition (NRBC) is considered for the solution of the Klein–Gordon equation. The infinite domain is truncated via an artificial boundary B, and a high-order NRBC is applied on B. Numerical examples, in various configurations, concerning the propagation of a pressure pulse are used to demonstrate the performance o...

Since 1997, the availability, in haematology laboratories of automated analyzers capable of performing an extended differential blood cell count, including the nucleated red blood cell (NRBC) count, allowed their experimental use to estimate the cell composition of bone marrow fluid. In 1999 we evaluated the Sysmex XE-2100 to detect the clinical usefulness of immature granulocyte (IG) and NRBC ...

The immediate and short term outcomes of term newborns with perinatal asphyxia were studied in relation to the nucleated red blood cell count at admission. The mean (SD) NRBC/100WBC (white blood cells) was significantly higher in sequelae group than normal [9.8 (98.9) vs. 2.9 (43); P=0.001].

BACKGROUND Nucleated red blood cells (NRBCs) in critically ill patients are associated with increased mortality and poor outcome. The aim of the present study was to evaluate the predictive value of NRBCs in patients with acute respiratory distress syndrome (ARDS). METHODS This observational study was conducted at an ARDS referral center and included patients from 2007 to 2014. Daily NRBC cou...

Objective: To compare the nucleated red blood cell (NRBC) counts of healthy and asphyxiated newborns as a key clinical indicator severity birth asphyxia short-term outcome. Methodology: This case control study was conducted at department neonatology Recep Tayyip Erdogan Hospital Muzaffargarh from June 2020 to November 2020. Study A total 112 term newborns, including 56 cases (with asphyxia) con...
