The management of remanufacturing activities requires new techniques in order to improve these systems for cost optimized operations. However, several factors make the operations of the reverse logistics process difficult. In particular, uncertainties in quantity, quality and timing of returns negatively affect remanufacturing activities such as production planning and inventory control. In thi...

Monocrystalline cubic and/or monoclinic Y2O3:Eu nanoparticles (10-50 nm) were synthesized continuously without post-processing by single-step flame spray pyrolysis (FSP). These particles were characterized by Xray diffraction (XRD), nitrogen adsorption (BET) and transmission electron microscopy (TEM). Photoluminescence (PL) emission was measured as well as the time-resolved PL-intensity decay. ...

Neighborhood social dynamics have been shown to impact behavioral development in residents, including levels of prosociality (i.e. positive social behavior). This study explores whether residential moves to neighborhoods with different social dynamics can influence further prosocial development. Prosociality, five domains of social support, and residential location were tracked between 2006 and...

This paper examines how the combination of simulated discharge and mean catchment residence time (MRT) may be used to subsume flow path process complexity and provide a simple, scalable evaluative data source for water quantity-quality based conceptual models at the catchment scale. A simple Monte Carlo framework is used to evaluate the identifiability of parameters, and how values of mean resi...

The method of analysis of the first temporal moment (mean residence time) of tracer return data was utilized to investigate the swept volume and fluid velocity between pairs of injection and production wells in the Dixie Valley geothermal field. Calculations were made using a spreadsheet program available from the Idaho National Laboratory. Jointly sponsored industry–government research at the ...

The aim of the study was to determine the apparent volume of distribution (VTOT), total body clearance (CL), fractional clearance, and mean residence time (MRT) of the β-cell hormone amylin. We therefore performed an intravenous injection of 50 μg of human synthetic amylin (amlintide) in nine healthy male subjects during suppression of endogenous amylin release by intravenous somatostatin (0.06...

Cotyledoside, a bufadienolide cardiac glycoside, was administered intravenously to sheep in 2 studies. In experiment 1, sheep (n = 4) received 0.0135 mg/kg daily on 5 consecutive days and in the 2nd experiment, sheep (n = 4) received 0.027 mg/kg as a single dose. Jugular blood was collected at different time intervals and kinetic parameters were determined. The data fitted a 1-compartmental mod...

The aim of this paper is to examine the association of individual demographic variables and area characteristics with the characteristics of sexual partners of American adolescents. Data for the study were drawn from the National Longitudinal Study of Adolescent Health. The data indicate that the community characteristics of ethnic or racial composition of the population and region were most st...
