Abstract (sommario):

Radium is a naturally occurring alkaline earth metal that is present in soils, water, plants, and foods in low concentrations. In the analysis of radium in trace amounts, co-precipitation is the favoured way of separating an element from its matrix. In this case, radium is co-precipitated with barium. The purity and yield of the extraction is controlled by adsorption onto the barium sulfate precipitate and pH manipulation controls the solubility of certain products. This technique enables the removal of interfering lead-210 to yield a purified radium source for analysis, which is done using li

Abstract (sommario):

Abstract Radium-228 (228Ra) and Radium-226 (226Ra) isotopes in drinking water are significant from the aspect of radiation protection and human health. In this paper, the three most common preconcentration methods, i.e.coprecipitation, absorption and evaporation, were reviewed with emphasis on routinely measurement techniques. The reviewed measurement techniques include low background γ-spectrometry, α-spectrometry and liquid scintillation counting. The γ-spectrometry technique is the good selection, when the maximum sensitivity is considered. The Environmental Protection Agency guideline has

Abstract (sommario):

The next generation of small gas turbines used as compact Auxiliary Power Units (APUs) in aircraft and mobile ground power applications will achieve higher power density than current installations by operating at substantially higher turbine inlet temperatures. Ceramics vs. advanced/cooled superalloy designs are compared as alternate paths to improved performance through increased turbine inlet temperature for the T-100 MPSPU (Multi-purpose Small Power Unit) technology demonstrator engine currently under development.

Data is presented herein at two circumferential and three radial locations. The pump was tested in two configurations; with the impeller running centered within the pump, and with the impeller orbiting with a synchronous motion (ϵ/r2). Variation in velocity profiles among the individual passages in the orbiting impeller were found. At design flow rat

Abstract (sommario):

The rate of fatalities at signalized intersections involving heavy vehicles is nearly five times higher than for passenger vehicles in the US. Previous studies in the US have found that heavy vehicles are twice as likely to violate a red light compared with passenger vehicles. Current technologies leverage setback detection to extend green time for a particular phase and are based upon typical deceleration rates for passenger cars. Furthermore, dilemma zone detectors are not effective when the max out time expires and forces the onset of yellow. This study proposes the use of connected vehicle
