Steam Reforming Application for Treatment of DOE Sodium Bearing Tank Wastes at INL for ICP

The patented THOR® steam reforming waste treatment technology has been selected as the technology of choice for treatment of Sodium Bearing Waste (SBW) at the Idaho National Laboratory (INL) for the Idaho Cleanup Project (ICP). SBW is an acidic tank waste at the Idaho Nuclear Technology and Engineering Center (INTEC) at INL. It consists primarily of waste from decontamination activities and laboratory wastes. SBW contains high concentrations of nitric acid, alkali and aluminum nitrates, with minor amounts of many inorganic compounds including radionuclides, mainly cesium and strontium. The THOR® steam reforming process will convert the SBW tank waste feed into a dry, solid, granular product. The THOR® technology was selected to treat SBW, in part, because it can provide flexible disposal options to accommodate the final disposition path selected for SBW. THOR® can produce a final end-product that will meet anticipated requirements for disposal as Remote-Handled TRU (RH-TRU) waste; and, with modifications, THOR® can also produce a final endproduct that could be qualified for disposal as High Level Waste (HLW). SBW treatment will be take place within the Integrated Waste Treatment Unit (IWTU), a new facility that will be located at the INTEC. This paper provides an overview of the THOR® process chemistry and process equipment being designed for the IWTU

Protein mass spectrometry detects multiple bloodmeals for enhanced Chagas disease vector ecology

Ecohealth-based approaches have been recognized as a sustainable method of Chagas disease control. Bloodmeal data and vector prevalence of various hosts fosters an understanding of local vector ecology and behavior. This detailed paper provides validation of the ability to detect multiple bloodmeals using synthetic hemoglobin reference peptides (SRPs) that differ among the previously reported most common bloodmeals. The study shows the superior ability of hemoglobin peptide-based LC-MS/MS to detect and identify Chagas disease vector bloodmeal sources (of field-collected Triatomine vectors from Guatemala), compared to classical DNA-based polymerase chain reaction (PCR)

The Boundary-spanning Role of Democratic Learning Communities: Implementing the IDEALS

This multi-case study investigates characteristics and practices in schools that expand the traditional boundaries of school leadership and transform schools into democratic learning communities based on the level of implementation of the IDEALS framework. This investigation serves as a modus to illuminate democratic processes that change schools and address the needs of the students, not the needs of the adults in the system. A sample of five purposefully selected high schools, from the Midwest USA, was utilized. The schools serve Grade 9—12 students, but vary in size, residential area and socioeconomic status of the students. This study illuminates some of the challenges and strategies that facilitate or impede the process of creating more democratic schools that expand the boundaries of inquiry and discourse to include a broader range of community stakeholders and that respect and embrace issues of equity.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
