Bell Canyon Test (BCT): cement development report (open access)

Bell Canyon Test (BCT): cement development report

The Borehole Plugging (BHP) materials development program which has been underway at WES under Sandia sponsorship for about five years is reviewed. Development testing data for candidate grout mixtures for the BCT plug are presented. Field batching, mixing, and placement operations are discussed. Data from field samples molded during the two plug placements include strength, expansion, compressional wave velocity, dynamic modulus, density, and porosity. Microstructure and composition are compared for grout samples at ages of a few weeks and one year.

Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction (open access)

Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction

Authors of the article assert that rate coefficients, k1(T), for the gas-phase reaction of the OH radical with Furan-2,5-dione (maleic anhydride (MA), C4H2O3), a biomass burning related compound, were measured under pseudo first-order conditions in OH using the pulsed laser photolysis - laser induced fluorescence method over a range of temperature and bath gas pressure. Their results are compared with a previous room temperature relative rate study of the OH + MA reaction and significant discrepancy between the studies is discussed. This is the accepted manuscript version of the published article.

Two legume fatty acid amide hydrolase isoforms with distinct preferences for microbial- and plant-derived acylamides (open access)

Two legume fatty acid amide hydrolase isoforms with distinct preferences for microbial- and plant-derived acylamides

Article describes how analysis of FAAHs from multiple angiosperm species, which revealed two conserved phylogenetic groups that differed in key conserved residues in the substrate binding pocket. The authors combined computational and biochemical approaches to compare the structural and enzymatic properties of two FAAH isoforms in the legume Medicago truncatula designated MtFAAH1 MtFAAH2a.

Feasibility of PROMIS using computerized adaptive testing during inpatient rehabilitation (open access)

Feasibility of PROMIS using computerized adaptive testing during inpatient rehabilitation

Article describes how there has been an increased significance on patient-reported outcomes in clinical settings. The authors aimed to evaluate the feasibility of administering patient-reported outcome measures by computerized adaptive testing (CAT) using a tablet computer with rehabilitation inpatients, assess workload demands on staff, and estimate the extent to which rehabilitation inpatients have elevated T-scores on six Patient Reported Outcomes Measurement Information System (PROMIS) measures.

Radioisotope Yields From 1.85-Gev Protons on Mo and 1.85- and 5.0-Gev Protons on Te (open access)

Radioisotope Yields From 1.85-Gev Protons on Mo and 1.85- and 5.0-Gev Protons on Te

Radioisotope yields from 1.85-GeV proton interactions in a natural isotopic composition Mo target and those from 1.85- and 5.0-GeV protons in natural Te targets were measured at Lawrence Berkeley Laboratory`s Bevatron. The radioisotope yields were determined by {gamma}-counting the targets using a 100-cm{sup 3} coaxial Ge detector following the irradiations. Cross sections were determined for the production of 31 radioactive nuclides, ranging from Z = 35, A = 74, to Z = 43, A = 97, from the Mo target and for 47 radioactive nuclides, ranging from Z = 35, A = 75, to Z = 53, A = 130 from the Te targets.

School counseling prevention programming to address social determinants of mental health (open access)

School counseling prevention programming to address social determinants of mental health

Article describes how school counselors can utilize the Advocating Student-within-Environment (ASE) theoretical lens as a liberation approach to strengthening students' capacity to overcome persistent adversity while addressing root causes of systemic oppression through policy change and advocacy at the school, community, and national levels. This study provides school counselors with an overview of ASE as a theoretical foundation for addressing social determinants of mental health in schools.

Atmospheric Fluidized Bed Combustion of Municipal Solid Waste: Test Program Results (open access)

Atmospheric Fluidized Bed Combustion of Municipal Solid Waste: Test Program Results

Air classified municipal solid waste (MSW) was fired in an atmospheric fluidized bed combustor at low excess air to simulate boiler conditions. The 7 ft/sup 2/ combustor at Combustion Power Company's energy laboratory in Menlo Park, CA, incorporates water tubes for heat extraction and recycles elutriated particles to the bed. System operation was stable while firing processed MSW for the duration of a 300-h test. Low excess air, low exhaust gas emissions, and constant bed temperature demonstrated feasibility of steam generation from fluidized bed combustion of MSW. During the 300-h test, combustion efficiency averaged 99%. Excess air was typically 44% while an average bed temperature of 1400/sup 0/F and an average superficial gas velocity of 4.6 fps were maintained. Typical exhaust emission levels were 30 ppM SO/sub 2/, 160 ppM NO/sub x/, 200 ppM CO, and 25 ppM hydrocarbons. No agglomeration of bed material or detrimental change in fluidization properties was experienced. A conceptual design study of a full scale plant to be located at Stanford University was based on process conditions from the 300-h test. The plant would produce 250,000 lb/hr steam at the maximum firing rate of 1000 tons per day (TPD) processed MSW. The average 800 TPD …
