Optimizing the Sensitivity of Particulate Silica Quantification by Molybdenum Blue Absorbance Spectrometry

Color poster with text, images, and graphs.The optimum initial pH (before addition of molybdate) for the dissolution of silica to form HPA is approx. pH 10. This may be due to the balance between enhanced silica solubility at high pH and the optimal (low) pH of the reaction to form HPA. As the acidic molybdate solution is added to the basic silica suspension to initiate the reaction, the initial solution pH quickly falls to approx. pH 1-2 for the formation of heteropoly blue. The objective of this research is to optimize analytical sensitivity for various types of silica.WiSys; Ar-WiTAG; University of Wisconsin--Eau Claire Office of Research and Sponsored Programs

Structured Dietary Management Dramatically Improves Marked Transaminitis, Metabolic and Clinical Profiles in Glycogen Storage Disease Type IXa

Glycogen storage disease type IXa (GSD IXa) presents in childhood with hepatomegaly, poor growth, and ketotic hypoglycemia. Clinical course is usually mild, often not requiring treatment with attenuation of symptoms with increasing age. The phenotypic spectrum has recently expanded to include more severe involvement with hepatic fibrosis or cirrhosis warranting dietary therapy. We report a 2-year-old boy with a severe phenotype of GSD IXa presenting with a massive hepatomegaly, significant transaminitis, recurrent ketotic hypoglycemia, and short stature. Aggressive dietary management with regular feeds, frequent uncooked cornstarch doses, and protein supplementation resulted in clinical improvements including enhanced growth velocity, energy levels, overall well-being, and reduction in hepatomegaly with restitutions in biochemical parameters. We concur with a recent report which proposed that GSD IXa is not always a mild condition but instead part of an expanding phenotypic spectrum warranting intensive dietary management to optimize metabolic control and quality of life

Climate Change Denial and Skepticism : A Topic Prevalence Analysis from Open-Ended Survey Questions in China and the United States

Color poster with text, charts, and images.The importance of global climate change in society cannot be overstated. China and the United States share prominent roles in the development of international climate change mitigation strategies. Citizen support is crucial for climate change mitigation policy action to occur. However, due to the complexity of the issue, public views are diverse and can be uninformed or misinformed. There is evidence that American opinions on climate change are influenced by sources advocating denial and skepticism. We analyzed responses to the open-ended survey question “What comes to mind when you hear the words ‘climate change’?”, to better understand public views on climate change, Surveys were conducted of Chinese and American citizens from May – October 2015. We investigated the frequency that words/topics associated with climate change realities appeared in American and Chinese responses respectively. We also examined the frequency that words/topics associated with climate change denial, skepticism and misunderstanding occurred among respondents in both countries.Blugold Commitment; International Fellows Program; University of Wisconsin--Eau Claire Office of Research and Sponsored Program

Examining Chinese and American Climate Change Views Using 2015, 2017 & 2020 Survey Data : Part 1-2

Color poster with text, images, charts, photographs, and graphs.With mounting scientific evidence regarding the realities of climate change (CC) including causes and consequences, the international/global importance of this issue cannot be overstated. Significant research has assessed public CC views in developed countries including the United States. However, much less is known about public CC views in developing countries, and in particular, in China. China and the US share a significant importance regarding international CC mitigation strategies as well as policy development because they are the world’s two largest greenhouse gas (GHG) polluters and also the two largest economies. Thus, a better understanding of Chinese and American views on CC is of great interest. Surveys were conducted in China and the US in 2015 (N=7,556), 2017 (N=7,415) and 2020 (N=2,600) to investigate a variety of issues regarding public views on CC in these two important countries. This presentation uses two posters to tell a comprehensive story of Chinese and American CC views using these data. The first part of this presentation constructs a CC Index based on a scoring system calculated from responses to eight survey questions yielding an easily understandable metric for comparing acceptance, knowledge, concern and obligation to act in the context of the scientific realities of CC. CC Index scores are compared across China and the US using aggregated data from 2015, 2017 and 2020 and an existing partisan political divide among American CC views is also highlighted. The second part of this presentation analyzes a variety of other data from survey questions regarding trust of science and media sources, support for the Paris Agreement, willingness-to-pay for CC policy action and exploring themes from responses to open-ended survey questions. Continued comparisons between Chinese and American CC views as well as the political divide on CC in the US are again presented using aggregated survey data from all three survey years.University of Wisconsin--Eau Claire Office of Research and Sponsored Program
