Alternative counting methods for the Abbott “AusR1A” hepatitis-associated antigen test have been devised and evaluated. These methods involve solubilization of the tube-bound radiolabeled complex with glacial acetic acid, transfer of the eluate to a counting vial of choice, and measurement by either a gamma scintillation or a liquid scintillation system. These methods, when compared to the dire...

chest tube (ct) or tube thoracostomy placement is often indicated following traumatic injuries. premature movement of the chest tube leads to increased hospital complications and costs for patients. placement of a chest tube is indicated in drainage of blood, bile, pus, drain air, and other fluids. although there is a general agreement for the placement of a chest tube, there is little consensu...

The distributions of the magnetic field inside and around a superconducting flux exclusion tube due to currents induced in the material by an external magnetic field are examined. A simple macroscopic model for the superconductor is assumed, based on the concept of a field-dependent critical current density, and London’s equations are used to calculate the magnetic potentials in the three regio...

Acoustic materials such as plastic carpet, gypsum board, styrofoam and plywood can be used to reduce sound intensity. Nevertheless, the existing research has generally focused on single-ingredient studies. In this research, optimum thickness of each material will sought based its efficiency in reducing intensity level. Besides that, various types also tested for level study, a resonator tube wa...

OBJECTIVES To use a utility-based Markov decision analysis model to compare outcomes of short-term grommet tympanostomy tubes (TTs), intermediate-type tubes, and permanent T-Tubes and to use a detailed sensitivity analysis to determine the most important factors influencing outcomes with one type of TT versus another. STUDY DESIGN Markov decision analysis. SETTING Hypothetical cohort. SUB...

Dielectric material between capacitor electrodes increases the capacitance. However, when the electric field exceeds a threshold, electric breakdown in the dielectric discharges the capacitor suddenly and the stored energy is lost. We show that nano vacuum tubes do not have this problem because (i) electric breakdown can be suppressed with quantization phenomena, and (ii) the capacitance is lar...

Greenville Tube Company (GT), a manufacturer of high-precision, small-diameter stainless steel tubing, conducted an in-house system performance optimization project to improve the efficiency of its No. 6 tube drawing bench. This tube drawing bench plays an integral role in the production process, but severely hindered the productivity and energy efficiency of the facility. GT’s plant engineer, ...

Unlike nanoscrolls of 2D graphene, those of 2D h-BN have not been demonstrated, except for only a few experimental reports. Nanoscrolls of h-BN with high yields and reproducibility are first synthesized by a simple solution process. Inner-tube diameters of BNSs including LCAs, N-(2-aminoethyl)-3α-hydroxy-5β-cholan-24-amide, a bile acid derivative and self-assembling material, can be controlled ...

Concrete filled tube (CFT) columns have been used as primary axial load-carrying members in high-rise building especially in seismic zones. The structural member has become popular as it has a number of distinct advantages over an equivalent steel, reinforced concrete, or steel-reinforce concrete structural member. This paper is intended to presents numerical modeling of elliptical concrete-fil...

Abstract Residual stresses in an unloaded configuration of elastic material have a significant influence on the response from that configuration, but effect residual stress stability material, whether loaded or unloaded, has only been addressed to limited extent. In this paper we consider level can be supported thick-walled circular cylindrical tube non-linearly without loss when subjected fixe...
