Nitric acid-organic mixtures surveyed for use in separation by anion exchange methods

Column elution-spectrographic analysis technique compares certain solvents directly to the methanol system, using inert rare earths instead of actinides. Distribution ratios for americium between 90 percent solvent, 10 percent 5 M nitric acid and Dowex 1 nitrate form resin for a large group of organics miscible in water was determined

“Failure Looks Like this Child is Still in Limbo”: Foster Parent Experiences of Failed Pre-adoptive Placements

poster abstractPre-adoptive or “waiting” children are those who have a case plan of adoption and/or whose parental rights have been terminated. There are currently over 107,000 pre-adoptive children in the United States, and on average, they have been living in foster care for over three years. A lack of permanency is associated with a milieu of negative consequences while achieving permanent, stable relationships is significant in developing a sense of self and overall, long-term well-being. Failed pre-adoptive placements represent a significant barrier to achieving permanency; however, the phenomenon of failed pre-adoptive placements has been underexplored. This study uses phenomenology, a philosophical method and study of experience, to explore how pre-adoptive foster parents make meaning of their experiences of failed pre-adoptive placements. Participants fostered at least one pre-adoptive child with the intent, willingness, and/or openness to adopt the child, but the placement did not result in an adoption and the child moved to an alternative placement. The primary research question for this study is “What is the experience of a foster parent who has had a failed pre-adoptive placement?” Findings from in-depth interviews reveal that pre-adoptive foster parents enter into pre-adoptive placements with multiple motivations and personal expectations. Experiences which do not confirm these expectations often contribute to decisions to end a pre-adoptive placement. Participants are at times motivated by fear and feel compelled to make decisions to end placements on behalf of alternative roles (i.e. biological mother, spouse, neighbor, etc.). Pre-adoptive parents appear to have a future orientation that serves as a guiding force in decisions to continue or end a pre-adoptive placement. Participants describe feelings of grief, loss, and inadequacy. Findings contribute to the body of knowledge and have implications for foster and pre-adoptive training and support and encourage greater understandings within child welfare for improved permanency planning and practice

Retail/wholesale trade employment directly related to population change in the nonmetro great plains

During 1950-90, the nonmetro civilian labor force declined except during the 1970’s. In the 1970’s, nonmetro manufacturing increased substantially, and the baby boom generation entered the labor force. By contrast, the retail/wholesale labor force increased in every decade except for the 1980’s. Several factors could have contributed to the decline in the retail/wholesale labor force, including population decline and the effects of large retail establishments

Statistical analysis and speciation modeling of copper in Oregon highway runoff

Low levels of copper have been shown to impair the olfactory system of threatened and endangered (T&E) salmon, decreasing their predator avoidance behavior and likely increasing mortality. However, only dissolved copper (dissCu) present as the cupric ion (Cu2+) and weakly complexed species are truly bioavailable. Previous studies indicate the vast majority of dissCu in natural waters is complexed with dissolved organic matter (DOM). Highway stormwater runoff is a significant source of dissCu to receiving waters. Assessing factors that may impact dissCu concentration and speciation in stormwater provides a framework for predicting when and where copper toxicity could be problematic. To approach this problem, a stormwater sampling effort was undertaken to examine impacts and correlations of site locale, traffic density, storm hydrology, the “first flush” effect and water quality parameters on measured dissCu concentrations in highway runoff. Analytically measured concentrations of key constituents in the stormwater were also entered into a chemical equilibrium model to predict copper speciation. The results of this study show that runoff from urban/high traffic sites, as well as runoff due to the “first flush” effect, exhibits the highest potential for copper toxicity. Furthermore, correlations of [dissCu] and Cu2+ with other variables are developed, the most meaningful of which suggests that hardness is the water quality parameter most directly (positively) associated with [Cu2+] due to competition with copper for binding sites on DOM

Low-Temperature Geothermal Resources of Washington

This report presents information on the location, physical characteristics, and water chemistry of low-temperature geothermal resources in Washington. The database includes 941 thermal (>20C or 68F) wells, 34 thermal springs, lakes, and fumaroles, and 238 chemical analyses. Most thermal springs occur in the Cascade Range, and many are associated with stratovolcanoes. In contrast, 97 percent of thermal wells are located in the Columbia Basin of southeastern Washington. Some 83.5 percent are located in Adams, Benton, Franklin, Grant, Walla Walla, and Yakima Counties. Yakima County, with 259 thermal wells, has the most. Thermal wells do not seem to owe their origin to local sources of heat, such as cooling magma in the Earth`s upper crust, but to moderate to deep circulation of ground water in extensive aquifers of the Columbia River Basalt Group and interflow sedimentary deposits, under the influence of a moderately elevated (41C/km) average geothermal gradient

Quinuclidine compounds differently act as agonists of Kenyon cell nicotinic acetylcholine receptors and induced distinct effect on insect ganglionic depolarizations

We have recently demonstrated that a new quinuclidine benzamide compound named LMA10203 acted as an agonist of insect nicotinic acetylcholine receptors. Its specific pharmacological profile on cockroach dorsal unpaired median neurons (DUM) helped to identify alpha-bungarotoxin-insensitive nAChR2 receptors. In the present study, we tested its effect on cockroach Kenyon cells. We found that it induced an inward current demonstrating that it bounds to nicotinic acetylcholine receptors expressed on Kenyon cells. Interestingly, LMA10203-induced currents were completely blocked by the nicotinic antagonist alpha-bungarotoxin. We suggested that LMA10203 effect occurred through the activation of alpha-bungarotoxin-sensitive receptors and did not involve alpha-bungarotoxin-insensitive nAChR2, previously identified in DUM neurons. In addition, we have synthesized two new compounds, LMA10210 and LMA10211, and compared their effects on Kenyon cells. These compounds were members of the 3-quinuclidinyl benzamide or benzoate families. Interestingly, 1 mM LMA10210 was not able to induce an inward current on Kenyon cells compared to LMA10211. Similarly, we did not find any significant effect of LMA10210 on cockroach ganglionic depolarization, whereas these three compounds were able to induce an effect on the central nervous system of the third instar M. domestica larvae. Our data suggested that these three compounds could bind to distinct cockroach nicotinic acetylcholine receptors
