    EESI's ''Ethanol, Climate Protection, Oil Reduction'' (ECO) electr[on]ic newsletter reaches out to the environmental and agricultural communities, state/local government officials and other interested parties, and provides a forum for dialogue about ''the potential benefits of ethanol--and particularly the expanded opportunities provided by cellulosic ethanol--with a special focus on climate protection.'' Each issue features expert commentary, excerpts from recent studies about ethanol, a summary of current government activity on ethanol, and ''notable quotables.'' The newsletter is distributed primarily via email and is also posted on EESI's web site. EESI also conducts outreach on the benefits of ethanol and other biofuels by attending and speaking at conferences, meetings and workshops around the country. The 16 issues of the newsletter published through December 2001 are included as attachments.

  2. Greenhouse-gas Consequences of US Corn-based Ethanol in a Flat World

    Competition for arable land is now occurring among food, fiber, and fuel production sectors. In the USA, increased corn production for ethanol has come primarily at the expense of reduced soybean production. Only a few countries, mainly Brazil, have appropriate soils, climate, and infrastructure needed for large absolute increases in cropped area in the next decade that could make up the lost US soybean production. Our objective is to improve estimates of the potential net greenhouse gas (GHG) consequences, both domestically and in Brazil, of meeting the new goals established by the US Congress for expansion of corn- based ethanol in the USA. To meet this goal of 57 billion liters per year of corn-based ethanol production, an additional 1-7 million hectares will need to be planted in corn, depending upon assumptions regarding future increases in corn yield. Net GHG emissions saved in the USA by substituting ethanol for gasoline are estimated at 14 Tg CO2-equivalents once the production goal of 57 million L/yr is reached. If reduced US soybean production caused by this increase in US corn planting results in a compensatory increase in Brazilian production of soybeans in the Cerrado and Amazon regions, we estimate a potential net release of 1800 to 9100 Tg CO2-equivalents of GHG emissions due to land-use change. Many opportunities exist for agricultural intensification that would minimize new land clearing and its environmental impacts, but if Brazilian deforestation is held to only 15% of the area estimated here to compensate lost US soybean production, the GHG mitigation of US corn-based ethanol production during the next 15 years would be more than offset by emissions from Brazilian land-use change. Other motivations for advancing corn-based ethanol production in the USA, such as reduced reliance on foreign oil and increased prosperity for farming communities, must be considered separately, but the greenhouse-gas-mitigation rationale is clearly unsupportable.

  3. Corn-based ethanol production compromises goal of reducing nitrogen export by the Mississippi River.

    Corn cultivation in the United States is expected to increase to meet demand for ethanol. Nitrogen leaching from fertilized corn fields to the Mississippi-Atchafalaya River system is a primary cause of the bottom-water hypoxia that develops on the continental shelf of the northern Gulf of Mexico each summer. In this study, we combine agricultural land use scenarios with physically based models of terrestrial and aquatic nitrogen to examine the effect of present and future expansion of corn-based ethanol production on nitrogen export by the Mississippi and Atchafalaya Rivers to the Gulf of Mexico. The results show that the increase in corn cultivation required to meet the goal of 15-36 billion gallons of renewable fuels by the year 2022 suggested by a recent U.S. Senate energy policy would increase the annual average flux of dissolved inorganic nitrogen (DIN) export by the Mississippi and Atchafalaya Rivers by 10-34%. Generating 15 billion gallons of corn-based ethanol by the year 2022 will increase the odds that annual DIN export exceeds the target set for reducing hypoxia in the Gulf of Mexico to >95%. Examination of extreme mitigation options shows that expanding corn-based ethanol production would make the already difficult challenges of reducing nitrogen export to the Gulf of Mexico and the extent of hypoxia practically impossible without large shifts in food production and agricultural management.

  4. Succinic Acid as a Byproduct in a Corn-based Ethanol Biorefinery

    2007-12-31

    MBI endeavored to develop a process for succinic acid production suitable for integration into a corn-based ethanol biorefinery. The project investigated the fermentative production of succinic acid using byproducts of corn mill operations. The fermentation process was attuned to include raw starch, endosperm, as the sugar source. A clean-not-sterile process was established to treat the endosperm and release the monomeric sugars. We developed the fermentation process to utilize a byproduct of corn ethanol fermentations, thin stillage, as the source of complex nitrogen and vitamin components needed to support succinic acid production in A. succinogenes. Further supplementations were eliminated without lowering titers and yields and a productivity above 0.6 g l-1 hr-1was achieved. Strain development was accomplished through generation of a recombinant strain that increased yields of succinic acid production. Isolation of additional strains with improved features was also pursued and frozen stocks were prepared from enriched, characterized cultures. Two recovery processes were evaluated at pilot scale and data obtained was incorporated into our economic analyses.

    Planning for a new CMS exhibition centre, next to the CMS Centre (Meyrin), is progressing well. The two rooms that form the exhibition will be divided into an "outreach" room and an "education" room, with the main target audience for both rooms being high school students (about 80% of all visitors to CERN). A global scenario for the exhibition has been developed by the CMS Outreach team in close collaboration with Juliette Davenne (who produced the ATLAS exhibition centre). The aim is to start civil engineering work in the summer and to have the centre operational in early 2010. Preliminary plans for a second exhibition site, at point 5, are also evolving, though on a longer timescale. Recently it has become clear that there are many models of the CMS detector in various institutes around Europe and the world. If you know of such a model please let the outreach team know by dropping us a line at cms.outreach@cern.ch Indeed any ideas for exhibits and hands-on interactive de...

    Feedback from users on the new CMS Outreach web site has been very encouraging, with a large majority of people finding the new navigation scheme and content clear and easy to use. Suggestions concerning content (in particular) are always welcome. Please send them to: outreach@cern.ch Compared with the LHC startup and mass media attention of the 10th September, the Official Inauguration of the LHC on the 21st October was a relatively subdued event. Even so, many VIPs visited the CMS experimental cavern and were left feeling awed and inspired. The ceremony itself, in the SM18 area at CERN (where all the dipoles were tested) was followed by a tour around a temporary exhibition area in the same building, where pieces of CMS were on display. These were accompanied by films of the lowering operations and preliminary versions of the "virtual reality" images from Peter McReady (soon to be available on the CMS Outreach web site), both of which were well received by the audience.

    The main emphasis for the coming months is clearly the Open Days of April 5th and 6th, in all likelihood the last opportunities that visitors will get to see the LHC underground installations. Tens of thousands of visitors are expected, especially on Sunday 6th - the Open Day for the General Public. As announced recently in a mail to the collaboration, CMS collaborators are encouraged to sign-up to be guides. If you are interested in doing this, please contact Catherine Brandt. In addition to guides, we require introductory talks to be given at point 5 and are looking for volunteers (many thanks to those of you who have already volunteered!). If you are interested, please send an email to outreach@cern.ch stating the languages you prefer and your availability on the 6th between 9am and 7pm.

    The two core activities of the Outreach group are the continued production of the CMS Times and the evolution of the Outreach web site. Although the former began life as a publication for CMS members it is increasingly being viewed by the public, as evidenced by the external subscribers (nearly 400) and the fact that it is one of the most popular sections of the web-site, with tens of thousands of hits every month. Indeed a statistical analysis of our web-site is underway and already we know that it is host to around 11000 distinct visitors per month with more than half a million pages being viewed! Recent additions to the web-site include several new "virtual reality" movies of CMS underground - ideal for presentations to the public etc. A big effort is also being made to archive the thousands of superb images of CMS taken over the years and our team have recently been interacting with the CERN "CDS" team in order to achieve this in the most efficient way possible.

    The past three months have been very eventful for the CMS Outreach team. The majority of our efforts have concentrated on the update of the public web site at http://www.cern.ch/cmsinfo which was released to the public in time for the first LHC circulating beams. Congratulations in particular to Marzena Lapka and Lizzie Gibney for the excellent job that they have done. The layout of the new site roughly follows that of the main CERN public web site, a decision made long ago so that surfers do not feel lost when they jump from CERN to CMS. Both ALICE and LHCb also made this decision (after us!). The text of the new pages was made after interviewing many CMS collaborators, so has a very human feel to it. The site has been very well received by the community and the public/press alike. This is of course a first version so there will be more to come in the future, and comments are more than welcome.

    The new underground visit itinerary to CMS was officially launched during the summer. Many hundreds of people from far and near have already been into the caverns and all come away feeling excited and awed. The visitors gallery on the surface has also seen some improvements, including pieces of equipment from most CMS sub-detectors. At the beginning of this CMS week the gallery will receive a further addition - a cosmic ray detector. This detector was made by high school students associated to the US "Quarknet" program and it is these students, together with Dan Karmgard (US-CMS Outreach Coordinator), who will install and commission it at point 5. The other main activity (apart from the CMS Times of course, which recently celebrated it's 1st anniversary!) is with the development of a new CMS public web site.

  13. Life-cycle assessment of corn-based butanol as a potential transportation fuel.

    Energy Technology Data Exchange (ETDEWEB)

    2007-12-31

    Butanol produced from bio-sources (such as corn) could have attractive properties as a transportation fuel. Production of butanol through a fermentation process called acetone-butanol-ethanol (ABE) has been the focus of increasing research and development efforts. Advances in ABE process development in recent years have led to drastic increases in ABE productivity and yields, making butanol production worthy of evaluation for use in motor vehicles. Consequently, chemical/fuel industries have announced their intention to produce butanol from bio-based materials. The purpose of this study is to estimate the potential life-cycle energy and emission effects associated with using bio-butanol as a transportation fuel. The study employs a well-to-wheels analysis tool--the Greenhouse Gases, Regulated Emissions and Energy Use in Transportation (GREET) model developed at Argonne National Laboratory--and the Aspen Plus{reg_sign} model developed by AspenTech. The study describes the butanol production from corn, including grain processing, fermentation, gas stripping, distillation, and adsorption for products separation. The Aspen{reg_sign} results that we obtained for the corn-to-butanol production process provide the basis for GREET modeling to estimate life-cycle energy use and greenhouse gas emissions. The GREET model was expanded to simulate the bio-butanol life cycle, from agricultural chemical production to butanol use in motor vehicles. We then compared the results for bio-butanol with those of conventional gasoline. We also analyzed the bio-acetone that is coproduced with bio-butanol as an alternative to petroleum-based acetone. Our study shows that, while the use of corn-based butanol achieves energy benefits and reduces greenhouse gas emissions, the results are affected by the methods used to treat the acetone that is co-produced in butanol plants.

    Corn is a major grain produced in northern China. Corn-based functional food products are very limited. In this study, a symbiotic corn-based yogurt-like product was developed. Corn milk was prepared through grinding, extrusion and milling, and hydration processes. Corn extrudate was prepared under the optimized conditions of corn flour particle size fermented at 35 °C for 6 h using a probiotic starter culture containing L. plantarum. Chemical composition (%) of the symbiotic corn-based yogurt-like product was: total solids (17.13 ± 0.31), protein (1.12 ± 0.03), fat (0.30 ± 0.05), carbohydrates (15.14 ± 0.19), and ash (0.16 ± 0.02), respectively. pH value of this symbiotic product decreased from 4.50 ± 0.03 to 3.88 ± 0.13 and the population of L. plantarum declined from 7.8 ± 0.09 to 7.1 ± 0.14 log CFU/mL during storage at 4 °C. SDS-PAGE analysis showed that there were no changes in protein profile during storage. Texture and consistency were also stable during the period of this study. It can be concluded that a set-type corn-based symbiotic yogurt-like product with good texture and stability was successfully developed that would be a good alternative to the dairy yogurt. © 2017 Institute of Food Technologists®.

    2017-06-01

    A modified biuret method suitable for protein determination of corn-based products was developed by introducing a combination of an alkaline reagent with sodium dodecyl sulfate (reagent A) and heat treatments. The method was tested on seven corn-based samples. The results showed mostly good agreement (P>0.05) as compared to the Kjeldahl values. The proposed method was found to enhance the accuracy of prediction on zein content using bovine serum albumin as standard. Reagent A and sample treatment were proved to effectively improve protein solubilization for the thermally-dried corn-based products, e.g. corn gluten meal. The absorbance was stable for at least 1-h. Moreover, the whole measurement of protein content only needs 15-20min more than the traditional biuret assay, and can be performed in batches. The findings suggest that the proposed method could be a timesaving alternative for routine protein analyses in corn processing factories. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Several studies have considered the sustainability of corn-based ethanol as produced in the US as a major fuel source from a technical perspective. However, not much attention has been paid to the market-based aspects of corn-based ethanol as a sustainable fuel. We address this question by offering an econometric analysis of the E85 (apparently the most viable of the potential substitutes for gasoline) market using demand and supply analysis. Reduced form price equation estimates indicate that the cross elasticity of E85's price with respect to the price of gasoline does not differ significantly from unity, so that any rise in gasoline prices will be matched (in percentage terms) by a corresponding rise in the price of E85. Thus, given the current market, which includes significant government subsidy, the prospect that E85 will ever be price competitive with gasoline is indeed dim. (author)

    Yang, Q.; Chen, G.Q.

    2012-01-01

    Nonrenewable energy cost is accounted for the believed renewable biofuel of corn-ethanol in China. By a process-based energy analysis, nonrenewable energy cost in the corn-ethanol production process incorporating agricultural crop production, industrial conversion and wastewater treatment is conservatively estimated as 1.70 times that of the ethanol energy produced, corresponding to a negative energy return in contrast to the positive ones previously reported. Nonrenewable energy cost associated with wastewater treatment usually ignored in previous researches is shown important in the energy balance. Denoting the heavy nonrenewability of the produced corn-ethanol, the calculated nonrenewable energy cost would rise to 3.64 folds when part of the nonrenewable energy cost associated with water consumption, transportation and environmental remediation is included. Due to the coal dominated nonrenewable energy structure in China, corn-ethanol processes in China are mostly a conversion of coal to ethanol. Validations and discussions are also presented to reveal policy implications against corn based ethanol as an alternative energy in long term energy security planning. - Highlights: ► Nonrenewable energy (NE) cost is conservatively accounted for corn-ethanol in China. ► Corn cultivation, ethanol conversion and wastewater treatment are included. ► NE cost is estimated as 1.70 times that of the ethanol energy produced. ► Corn-ethanol processes in China are mostly a conversion of coal to ethanol.

    Resistant starch is one important component determining the characteristics of a functional food. The aim of the research was to determine the cooling time optimum in the autoclaving-cooling treatment to increase the resistance starch content corn-based rice analogues, with 6 level of cooling time (0 hours/control, 12 hours, 24 hours, 36 hours, 48 hours and 60 hours). The results showed that cooling at 4°C for 60 hours would increase the resistant starch content (6.27% to 15.38%), dietary fiber content (14.53% to 20.17%); and decrease the digestible starch content (61.81% to 52.70%). Cooling time level at 4°C for 24 hours, would increase the sensory score of corn-based rice analogues then back down until cooling time level of 60 hours. Microscopic analysis of granular structure using SEM indicated that cooling time had a linear correlation with cracks intensity on the granule surface of the corn-based rice analogues. The high content of resistant starch showed that the application of cooling time level at 4°C for 24 hours would improve the functional properties of corn-based rice analogues with sensory characteristics remain favorable to panelists.

    The NASA Microgravity Research Program has been actively developing classroom activities and educator's guides since the flight of the First United States Microgravity Laboratory. In addition, various brochures, posters, and exhibit materials have been produced for outreach efforts to the general public and to researchers outside of the program. These efforts are led by the Microgravity Research Outreach/Education team at Marshall Space Flight Center, with classroom material support from the K-12 Educational Program of The National Center for Microgravity Research on Fluids and Combustion (NCMR), general outreach material development by the Microgravity Outreach office at Hampton University, and electronic/media access coordinated by Marshall. The broad concept of the NCMR program is to develop a unique set of microgravity-related educational products that enable effective outreach to the pre-college community by supplementing existing mathematics, science, and technology curricula. The current thrusts of the program include summer teacher and high school internships during which participants help develop educational materials and perform research with NCMR and NASA scientists; a teacher sabbatical program which allows a teacher to concentrate on a major educational product during a full school year; frequent educator workshops held at NASA and at regional and national teachers conferences; a nascent student drop tower experiment competition; presentations and demonstrations at events that also reach the general public; and the development of elementary science and middle school mathematics classroom products. An overview of existing classroom products will be provided, along with a list of pertinent World Wide Web URLs. Demonstrations of some hands on activities will show the audience how simple it can be to bring microgravity into the classroom.

    We estimated the effects on per-vehicle-mile fuel-cycle petroleum use, greenhouse gas (GHG) emissions, and energy use of using ethanol blended with gasoline in a mid-size passenger car, compared with the effects of using gasoline in the same car. Our analysis includes petroleum use, energy use, and emissions associated with chemicals manufacturing, farming of corn and biomass, ethanol production, and ethanol combustion for ethanol; and petroleum use, energy use, and emissions associated with petroleum recovery, petroleum refining, and gasoline combustion for gasoline. For corn-based ethanol, the key factors in determining energy and emissions impacts include energy and chemical usage intensity of corn farming, energy intensity of the ethanol plant, and the method used to estimate energy and emissions credits for co-products of corn ethanol. The key factors in determining the impacts of cellulosic ethanol are energy and chemical usage intensity of biomass farming, ethanol yield per dry ton of biomass, and electricity credits in cellulosic ethanol plants. The results of our fuel-cycle analysis for fuel ethanol are listed below. Note that, in the first half of this summary, the reductions cited are per-vehicle-mile traveled using the specified ethanol/gasoline blend instead of conventional (not reformulated) gasoline. The second half of the summary presents estimated changes per gallon of ethanol used in ethanol blends. GHG emissions are global warming potential (GWP)-weighted, carbon dioxide (CO2)-equivalent emissions of CO2, methane (CH4), and nitrous oxide (N2O)

    This paper outlines the planning and effort that goes into a successful, inexpensive outreach project. Since 1996, the National Renewable Energy Laboratory has had an educational exhibit booth and has also presented workshops on renewable energy at the two-week-long National Western Stock Show held each January in Denver, Colorado. In our exhibit booth and workshops, farmers, ranchers, and homeowners learn how solar, wind, and biomass energy systems can provide economical electricity for the agricultural community. We show how this outreach has grown to include the presentation of renewable energy exhibits at events in South Dakota and Illinois at the request of the Deputy Secretary for Energy of the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy, and our support of the U.S. Department of Agriculture in Kansas and Nebraska on the issuance of the 2004 Farm Bill.

    Despite residing in a state with 75% of North American earthquakes and three of the top 15 ever recorded, most Alaskans have limited knowledge about the science of earthquakes. To many, earthquakes are just part of everyday life, and to others, they are barely noticed until a large event happens, and often ignored even then. Alaskans are rugged, resilient people with both strong independence and tight community bonds. Rural villages in Alaska, most of which are inaccessible by road, are underrepresented in outreach efforts. Their remote locations and difficulty of access make outreach fiscally challenging. Teacher retention and small student bodies limit exposure to science and hinder student success in college. The arrival of EarthScope's Transportable Array, the 50th anniversary of the Great Alaska Earthquake, targeted projects with large outreach components, and increased community interest in earthquake knowledge have provided opportunities to spread information across Alaska. We have found that performing hands-on demonstrations, identifying seismological relevance toward career opportunities in Alaska (such as natural resource exploration), and engaging residents through place-based experience have increased the public's interest and awareness of our active home.

  14. An Indirect Route for Ethanol Production

    Energy Technology Data Exchange (ETDEWEB)

    2005-04-29

    The ZeaChem indirect method is a radically new approach to producing fuel ethanol from renewable resources. Sugar and syngas processing platforms are combined in a novel way that allows all fractions of biomass feedstocks (e.g. carbohydrates, lignins, etc.) to contribute their energy directly into the ethanol product via fermentation and hydrogen based chemical process technologies. The goals of this project were: (1) Collect engineering data necessary for scale-up of the indirect route for ethanol production, and (2) Produce process and economic models to guide the development effort. Both goals were successfully accomplished. The projected economics of the Base Case developed in this work are comparable to today's corn based ethanol technology. Sensitivity analysis shows that significant improvements in economics for the indirect route would result if a biomass feedstock rather that starch hydrolyzate were used as the carbohydrate source. The energy ratio, defined as the ratio of green energy produced divided by the amount of fossil energy consumed, is projected to be 3.11 to 12.32 for the indirect route depending upon the details of implementation. Conventional technology has an energy ratio of 1.34, thus the indirect route will have a significant environmental advantage over today's technology. Energy savings of 7.48 trillion Btu/yr will result when 100 MMgal/yr (neat) of ethanol capacity via the indirect route is placed on-line by the year 2010.

    Full Text Available In this study, fungal contamination was determined as well as total aflatoxin B1(AB1, ochratoxin A (OTA and zearalenon (ZEA levels in corn-based feed samples obtained from four different farms in Serbia (n=35 during one year. Mycotoxins were detected in feed using the VICAM fluorometric method. It was determined that 97.14% of all samples were contaminated with moulds which belonged to following genera: Absidia, Acremonium, Aspergillus, Cladosporium, Geotrichum, Eurotium, Fusarium, Mucor, Mortierella, Oidiodendron, Penicillium, Rhizopus, Scopulariopsis, Syncephalastrum, Trichoderma, Ulocladium and Wallrothiella. A total of 58 different species were identified. Total mould count per 1 g ranged from 1.00 log cfu/g (dried corn silage - autumn, fresh corn silage - summer and corn grain silage - spring to 7.32 log cfu/g (dried corn silage - winter. Mycotoxins were isolated from 28.5% of samples: ZEA was found in summer (220-240 μg/kg and in spring (240 μg/kg in concentrate samples; OTA was detected in winter in dried corn silage (16 μg/kg and in spring (12 μg/kg; all samples were AB1 free.

    A simple, fast, and robust method was developed for the determination of fumonisin B1 (FB1), fumonisin B2 (FB2), and fumonisin B3 (FB3) in corn-based human food and animal feed (cornmeal). The method involves a single extraction step followed by centrifugation and filtration before analysis by ultra-performance liquid chromatographylelectrospray ionization (UPLC/ESI)-MS/MS. The LC/MS/MS method developed here represents the fastest and simplest procedure (<30 min) among both conventional HPLC methods and other LC/MS methods using SPE cleanup. The potential for high throughput analysis makes the method particularly beneficial for regulatory agencies and analytical laboratories with a high sample volume. A single-laboratory validation was conducted by testing three different spiking levels (200, 500, and 1000 ng/g for FB1 and FB2; 100, 250, and 500 ng/g for FB3) for accuracy and precision. Recoveries of FB1 ranged from 93 to 98% with RSD values of 3-8%. Recoveries of FB2 ranged from 104 to 108%, with RSD values of 2-6%. Recoveries of FB3 ranged from 94 to 108%, with RSD values of 2-5%.

  17. Optimizing Blendstock Composition and Ethanol Feedstock to Reduce Gasoline Well-to-Pump CO 2 Emission

    2017-06-02

    Lifecycle CO2 emission of ethanol blended gasoline was simulated to investigate how fuel properties and composition affect overall emission. Fuel research octane number (RON), octane sensitivity and ethanol content (derived from sugarcane and corn) were varied in the simulations to formulate blended fuels that economically achieve target specifications. The well-to-pump (WTP) simulation results were then analyzed to understand the effects of fuel composition on emission. Elevated ethanol content displaces aromatics and olefins required in gasoline blendstock to reach a target fuel specification. The addition of greater sugarcane-based ethanol percentage in constant aromatics and olefins fuel reduces its WTP CO2 emission. Corn-based ethanol blending does not offer CO2 emission offset due to its high production emissions. The mixing of sugarcane-based with corn-based ethanol is shown to be a potentially effective method for achieving a blended fuel with a lower lifecycle CO2 emission. Besides CO2 emission, the total greenhouse gas (GHG) emission from land-use conversions (LUC), CH4, and N2O are also significant in determining the optimal fuel blend. Herein, we present preliminary results showing that total GHG emissions significantly increase when either corn or sugarcane ethanol is blended at even small percentages; detailed results will be addressed in future communications.

  20. Greenhouse gas impacts of ethanol from Iowa corn: Life cycle assessment versus system wide approach

    2010-01-01

    Life cycle assessment (LCA) is the standard approach used to evaluate the greenhouse gas (GHG) benefits of biofuels. However, the need for the appropriate use of LCA in policy contexts is highlighted by recent findings that corn-based ethanol may actually increase GHG emissions. This is in contrary to most existing LCA results. LCA estimates can vary across studies due to heterogeneities in inputs and production technology. Whether marginal or average impacts are considered can matter as well. Most important of all, LCA is product-centered. The determination of the impact of biofuels expansion requires a system wide approach (SWA) that accounts for impacts on all affected products and processes. This paper presents both LCA and SWA for ethanol based on Iowa corn. LCA was conducted in several different ways. Growing corn in rotation with soybean generates 35% less GHG emissions than growing corn after corn. Based on average corn production, ethanol's GHG benefits were lower in 2007 than in 2006 because of an increase in continuous corn in 2007. When only additional corn was considered, ethanol emitted about 22% less GHGs than gasoline. SWA was applied to two simple cases. Using 2006 as a baseline and 2007 as a scenario, corn ethanol's benefits were about 20% of the emissions of gasoline. If geographical limits are expanded beyond Iowa, then corn ethanol could generate more GHG emissions than gasoline. These results highlight the importance of boundary definition for both LCA and SWA.

    France's Europort South community lives cheek by jowl with the chemical industry, with major complexes at For, Berre, and Lavera. Xavier Segond, technical adviser at the regional chemical industry association, Le Syndicat General des Industries Chimiques Provence-Alpes-Cote d'Azur Corse (SGIC), says a good relationship has grown over a period of 20 years. Segond describes Arco Chimie as an effective driving force for the Responsible Care effort in the region - partly because its US parent introduced the program on a worldwide basis in 1989, ahead of national industry association Union des Industries Chimiques (UIC; Paris). Arco's F2-billion ($373 million)/year Fos-sur-Mer site makes it a significant player. But in 1986 the company was a complete newcomer. We came to Fos as a US company, we had no Paris headquarters or French president, explains Dominique Lequeux, director/human resources. The community viewed the company with a mixture of curiosity and enthusiasm as a potential employer - about 330 people now work at the site. The day before the officials propylene oxide plant opening, we invited in local people, says Lequeux. That formed a good basis for its Responsible Care community outreach program. Now, schools, professional groups, and political groups make 20-25 plant visits each year

  3. Lifecycle optimized ethanol-gasoline blends for turbocharged engines

    This study presents a lifecycle (well-to-wheel) analysis to determine the CO2 emissions associated with ethanol blended gasoline in optimized turbocharged engines. This study provides a more accurate assessment on the best-achievable CO2 emission of ethanol blended gasoline mixtures in future engines. The optimal fuel blend (lowest CO2 emitting fuel) is identified. A range of gasoline fuels is studied, containing different ethanol volume percentages (E0–E40), research octane numbers (RON, 92–105), and octane sensitivities (8.5–15.5). Sugarcane-based and cellulosic ethanol-blended gasolines are shown to be effective in reducing lifecycle CO2 emission, while corn-based ethanol is not as effective. A refinery simulation of production emission was utilized, and combined with vehicle fuel consumption modeling to determine the lifecycle CO2 emissions associated with ethanol-blended gasoline in turbocharged engines. The critical parameters studied, and related to blended fuel lifecycle CO2 emissions, are ethanol content, research octane number, and octane sensitivity. The lowest-emitting blended fuel had an ethanol content of 32 vol%, RON of 105, and octane sensitivity of 15.5; resulting in a CO2 reduction of 7.1%, compared to the reference gasoline fuel and engine technology. The advantage of ethanol addition is greatest on a per unit basis at low concentrations. Finally, this study shows that engine-downsizing technology can yield an additional CO2 reduction of up to 25.5% in a two-stage downsized turbocharged engine burning the optimum sugarcane-based fuel blend. The social cost savings in the USA, from the CO2 reduction, is estimated to be as much as $187 billion/year. © 2016 Elsevier Ltd

    The Outreach Project was initiated in October 1994 with the objective of developing a multi-year plan for the U.S. Department of Energy (DOE) for targeted outreach activities for stakeholders in industry and the general public. This status report summarizes the work on industry outreach that has been completed since the inception of the project in October 1994. A three-pronged approach was taken to ascertain issues related to industry outreach. First, there was a review of on-going and past industry outreach activities at DOE and NHA. Next, a series of meetings with industry decision makers was arranged to get a better understanding of industry interests and concerns, and to discuss how DOE and industry could work collaboratively to develop hydrogen energy systems. Third, a workshop is scheduled where representatives from industry, DOE and other federal agencies can identify issues that would enhance partnering between the federal government and industry in the development of hydrogen energy systems. At this tiny, the review of on-going and past activities has been completed. Industry interviews are in progress and a majority of meetings have been held. Analysis of the information gained is in progress. The preliminary analysis of this information indicates that for appropriate near-term demonstration-type projects, the level of interest for collaboration between DOE and industry is high. The data also identifies issues industry is concerned with which impact the commercialization of hydrogen energy systems.

    The Centennial of Flight Education Outreach project worked with community partners to disseminate NASA Education materials and the Centennial of Flight CD-ROM as a vehicle to increase national awareness of NASA's Aerospace Education products, services and programs. The Azimuth Education Foundation and the Ninety Nines, an International Women Pilots Association, Inc. were chartered to conduct education outreach to the formal and informal educational community. The Dryden Education Office supported the development of a training and information distribution program that established a national group of prepared Centennial of Flight Ambassadors, with a mission of community education outreach. These Ambassadors are members of the Ninety Nines and through the Azimuth Foundation, they assisted the AECC on the national level to promote and disseminate Centennial of Flight and other educational products. Our objectives were to explore partnership outreach growth opportunities with consortium efforts between organizations. This project directly responded to the highlights of NASA s Implementation Plan for Education. It was structured to network, involve the community, and provide a solid link to active educators and current students with NASA education information. Licensed female pilots who live and work in local communities across the nation carried the link. This partnership has been extremely gratifying to all of those Ninety-Nines involved, and they eagerly look forward to further work opportunities.

    Full Text Available Objective This experiment was conducted to evaluate the effects of a corn- or cassava- based diet on the production of meat-type ducks. Methods Four hundred day-old ducks were used in this experiment. They were divided into five groups with each group replicated eight times. The ducks fed the corn-based diets served as the control group. The four other groups comprised different treatments, with each one given the cassava-based diet based on phase-feeding. Three treatments were fed the cassava-based diet from 16, 28, and 35 d; respectively up to 42 d of age and the other group was fed the cassava-based diet from 1 to 42 d of age. Results The results indicated that ducks on either the corn- or cassava-based diets were similar in growth during 1 to 9 d of age. However, toward 35 to 42 d, the cassava-diet produced a higher weight gain (p<0.05. The cassava-based diet was better than the corn-based diet at increasing the outer and inner breast weights at 28, 35, or 42 d (p<0.05. In contrast, the corn-based diet was better at increasing abdominal fat (p<0.05. The two diets did not differ in their effects on the serum triglyceride, cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, very-low-density lipoprotein-cholesterol, and liver cholesterol. The corn-based diet, however, caused a highly significantly greater level of liver triglyceride (p<0.01. Conclusion The results of this study suggest that both the cassava- and corn- based diets are similar in their effect on meat-type ducks during the starter stage but toward the finisher stage, the cassava-based diet has a better influence on weight gain and carcass characteristics.

    This paper summarizes the research of Monte Carlo simulation-based Economic, Energy and Environmental (3E) Life Cycle Assessment (LCA) of the three Biomass-based Fuel Ethanol (BFE) projects in China. Our research includes both theoretical study and case study. In the theoretical study part, 3E LCA models are structured, 3E Index Functions are defined and the Monte Carlo simulation is introduced to address uncertainties in BFE life cycle analysis. In the case study part, projects of Wheat-based Fuel Ethanol (WFE) in Central China, Corn-based Fuel Ethanol (CFE) in Northeast China, and Cassava-based Fuel Ethanol (CFE) in Southwest China are evaluated from the aspects of economic viability and investment risks, energy efficiency and airborne emissions. The life cycle economy assessment shows that KFE project in Guangxi is viable, while CFE and WFE projects are not without government's subsidies. Energy efficiency assessment results show that WFE, CFE and KFE projects all have positive Net Energy Values. Emissions results show that the corn-based E10 (a blend of 10% gasoline and 90% ethanol by volume), wheat-based E10 and cassava-base E10 have less CO 2 and VOC life cycle emissions than conventional gasoline, but wheat-based E10 and cassava-based E10 can generate more emissions of CO, CH 4 , N 2 O, NO x , SO 2 , PM 10 and corn-based E10 can has more emissions of CH 4 , N 2 O, NO x , SO, PM 10 .

    We studied the effects of supplementing N as distillers dried grains with solubles (DDGS) or urea to steers consuming corn-based diets. Six ruminally and duodenally cannulated steers (244 kg) were used in 2 concurrent 3 x 3 Latin squares and fed 1 of 3 corn-based diets: control (10.2% CP), urea (13.3% CP), or DDGS (14.9% CP). Periods were 14 d, with 9 d for adaptation and 5 d for collection of urine and feces. Urinary (15)N(15)N-urea enrichments, resulting from venous infusions of (15)N(15)N-urea, were used to measure urea kinetics. Dry matter intake (6.0 kg/d) was not affected by treatment, but N intake differed (99, 151, and 123 g/d for the control, DDGS, and urea treatments, respectively). Urea-N synthesis tended to be greater (P = 0.09) for DDGS (118 g/d) than for the control treatment (52 g/d), with the urea treatment (86 g/d) being intermediate. Urea-N excreted in the urine was greater (P urea treatments (29 g/d) than for the control treatment (13 g/d). Gastrointestinal entry of urea-N was not statistically different among treatments (P = 0.25), but was numerically greatest for DDGS (83 g/d), intermediate for urea (57 g/d), and least for the control (39 g/d). The amount of urea-N returned to the ornithine cycle tended to be greater (P = 0.09) for the DDGS treatment (47 g/d) than for the urea (27 g/d) or control treatment (16 g/d). The fraction of recycled urea-N that was apparently used for anabolism tended (P = 0.14) to be greater for the control treatment (0.56) than for the DDGS treatment (0.31), with the urea treatment (0.45) being intermediate, but no differences were observed among treatments in the amount of urea-N used for anabolism (P = 0.66). Urea kinetics in cattle fed grain-based diets were largely related to the amount of N consumed. The percentage of urea production that was captured by ruminal bacteria was greater (P urea treatment (22%), but the percentage of duodenal microbial N flow that was derived from recycled urea-N tended (P = 0.10) to

  14. Design and analysis of fuel ethanol production from raw glycerol

    Three configurations for fuel ethanol production from raw glycerol using Escherichia coli were simulated and economically assessed using Aspen Plus and Aspen Icarus, respectively. These assessments considered raw glycerol (60 wt%) purification to both crude glycerol (88 wt%) and pure glycerol (98 wt%). The highest purification cost (PC) was obtained using pure glycerol due to its higher energy consumption in the distillation stage. In addition, the remaining methanol in the raw glycerol stream was recovered and recycled, decreasing the purification costs. The E. coli strain is able to convert crude glycerol (at 10 g/L or 20 g/L), or pure glycerol (at 10 g/L) to ethanol. Among these three glycerol concentrations, the lowest bioconversion cost was obtained when crude glycerol was diluted at 20 g/L. Purification and global production costs were compared with the commercial prices of glycerol and fuel ethanol from corn and sugarcane. Purification costs of raw glycerol were lower than previously reported values due to the methanol recovery. Global production costs for fuel ethanol from glycerol were lower than the reported values for corn-based production and higher than those for cane-based production. (author)

    Extractive fermentation is a technique that can be used to reduce the effect of end-product inhibition through the use of a water-immiscible phase which removes fermentation products in situ. This has the beneficial effect of not only removing inhibitory products as they are formed (thus keeping reaction rates high) but also has the potential for reducing product recovery costs. We have chosen to examine the ethanol fermentation as a model system for end product inhibition and extractive fermentation, and have developed a computer model predicting the productivity enhancement possible with this technique. The model predicts an ethanol productivity of 82.6 g/L-h if a glucose feed of 750 g/L is fermented with a solvent having a distribution coefficient of 0.5 at a dilution rate of 5.0 h . This is more than 10 times higher than for a conventional chemostat fermentation of a 250 g/L glucose feed. In light of this, a systematic approach to extractive fermentation has been undertaken involving the screening of more than 1,000 solvents for their extractive properties. UNIFAC and UNIQUAC estimates of distribution coefficients and selectivities were compiled and ranked in a database, together with other important physical properties, such as density, surface tension and viscosity. Preliminary shake-flask and chemostat biocompatibility studies on the most promising solvents have been undertaken. The previous predictive, data base and experimental results are discussed.

    Background Variations in sugar yield due to genotypic qualities of feedstock are largely undescribed for pilot-scale ethanol processing. Our objectives were to compare glucose and xylose yield (conversion and total sugar yield) from straw of five winter wheat cultivars at three enzyme loadings (2.......5, 5 and 10 FPU g-1 dm pretreated straw) and to compare particle size distribution of cultivars after pilot-scale hydrothermal pretreatment. Results Significant interactions between enzyme loading and cultivars show that breeding for cultivars with high sugar yields under modest enzyme loading could...... be warranted. At an enzyme loading of 5 FPU g-1 dm pretreated straw, a significant difference in sugar yields of 17% was found between the highest and lowest yielding cultivars. Sugar yield from separately hydrolyzed particle-size fractions of each cultivar showed that finer particles had 11% to 21% higher...

  17. OUTREACH

    CERN Multimedia

    D. Barney

    The CMS public web site is taking shape, with priority being given to a user-friendly interface to multimedia (photos, movies, podcasts). We expect that this part of the web-site will be fully operational by the end of the year. As we all know, 2008 will be a very special year for LHC and CMS. Not only will everything start to be commissioned, but underground visits to CMS and the other LHC installations will cease. Reflecting this, the CERN DG has decided to hold an "Open Weekend" in early April 2008, to give visitors a final opportunity to go underground. Saturday 5th April will be reserved for people who work at CERN and their families. Sunday 6th will be for the public, with priority being given to local residents. Preparations are already underway at Point 5 to cope with the thousands of visitors expected on those days, including a recent meeting with the Maire of Cessy. In addition to point 5, there will also be CMS visit sites at Meyrin building 40, CMS analysis centre, crystal la...

    Excitement is growing as the finalization of CMS and the startup of the LHC approaches – and not just from within our community. The lowering of the central section of CMS – YB0 – at the end of February attracted "an unprecedented amount of media coverage" from the world’s press. Hungry for more, the press again converged on CMS for an event organised in March to mark the completed milestone of YB0 lowering and to thank the fund¬ing agencies and all those who provided support. CERN has since been inundated with visits from journalists, both individually (e.g. a visit from Dutch newspaper "De volkskrant" at the end of May) and in groups (e.g. a visit of around 20 journalists from Norway, also at the end of May) – all of whom visit CMS. In addition to these events at point 5, there have also been local celebrations of important milestones around the world that have witnessed excellent coverage in the media, both prin...

    The University of Washington League of Astronomers (LOA) is an organization comprised of University of Washington (UW) undergraduate students. Our main goal is to share our interest in astronomy with the UW community and with the general public. The LOA hosts star parties on the UW campus and collaborates with the Seattle Astronomical Society (SAS) on larger Seattle-area star parties. At the star parties, we strive to teach our local community about what they can view in our night sky. LOA members share knowledge of how to locate constellations and use a star wheel. The relationship the LOA has with members of SAS increases both the number of events and people we are able to reach. Since the cloudy skies of the Northwest prevent winter star parties, we therefore focus our outreach on the UW Mobile Planetarium, an inflatable dome system utilizing Microsoft’s WorldWide Telescope (WWT) software. The mobile planetarium brings astronomy into the classrooms of schools unable to travel to the UW on-campus planetarium. Members of the LOA volunteer their time towards this project and we make up the majority of the Mobile Planetarium volunteers. Our outreach efforts allow us to connect with the community and enhance our own knowledge of astronomy.

    The US is currently the world's largest ethanol producer. An increasing percentage is used as transportation fuel, but debates continue on its costs competitiveness and energy balance. In this study, technological development of ethanol production and resulting cost reductions are investigated by using the experience curve approach, scrutinizing costs of dry grind ethanol production over the timeframe 1980-2005. Cost reductions are differentiated between feedstock (corn) production and industrial (ethanol) processing. Corn production costs in the US have declined by 62% over 30 years, down to 100$ 2005 /tonne in 2005, while corn production volumes almost doubled since 1975. A progress ratio (PR) of 0.55 is calculated indicating a 45% cost decline over each doubling in cumulative production. Higher corn yields and increasing farm sizes are the most important drivers behind this cost decline. Industrial processing costs of ethanol have declined by 45% since 1983, to below 130$ 2005 /m 3 in 2005 (excluding costs for corn and capital), equivalent to a PR of 0.87. Total ethanol production costs (including capital and net corn costs) have declined approximately 60% from 800$ 2005 /m 3 in the early 1980s, to 300$ 2005 /m 3 in 2005. Higher ethanol yields, lower energy use and the replacement of beverage alcohol-based production technologies have mostly contributed to this substantial cost decline. In addition, the average size of dry grind ethanol plants increased by 235% since 1990. For the future it is estimated that solely due to technological learning, production costs of ethanol may decline 28-44%, though this excludes effects of the current rising corn and fossil fuel costs. It is also concluded that experience curves are a valuable tool to describe both past and potential future cost reductions in US corn-based ethanol production

    2005-08-01

    Carl Sagan set an example to all scientists when he encouraged us to reach out to the public and share the excitement of discovery and exploration. The prejudice that ensued did not deter Sagan and, with the passing of years, more and more scientists have followed his example. Although at present scientists at all ranks are encouraged by their institutions to do outreach, the balancing of a successful scientific career with teaching and outreach is often not an easy one. Young scientists, in particular, may worry about how their outreach efforts are viewed in the community and how they will find the time and energy for these efforts. This talk will offer suggestions on how to balance an active science research program with outreach activities, the many different ways to engage in education and public outreach, and how the rewards are truly priceless.

  7. An energy analysis of ethanol from cellulosic feedstock. Corn stover

    The shift from fossil resources to renewables for energy and materials production has been the driving force for research on energy analysis and environmental impact assessment of bio-based production. This study presents a detailed energy analysis of corn stover based ethanol production using advanced cellulosic technologies. The method used differs from that in LCA and from major studies on the subject as published in Science in two respects. First, it accounts for all the co-products together and so mainly avoids the allocation problems which plague all LCA studies explicitly and other studies implicitly. Second, the system boundaries only involve the content of the energy products used in the system but not the production processes of these energy products, like refining and electricity production. We normalized the six Science studies to this unified method. The resulting values of the total energy product use in both agricultural production and biomass conversion to ethanol are lower than these literature values. LCA-type of values including energy conversion would systematically be higher, in our case study around 45%. The net energy value of cellulosic ethanol production is substantially higher than the ones of the corn-based technologies, and it is similar to incineration and gasification for electricity production. The detailed analysis of energy inputs indicates opportunities to optimize the system. This form of energy analysis helps establishing models for the analysis of more complex systems such as biorefineries. (author)

    2016-03-01

    CERN's communication goes beyond publishing scientific results. Education and outreach are equally important ways of communicating with the general public, and in particular with the young generation. Over the last decade, CERN has significantly increased its efforts to accommodate the very large interest of the general public (about 300,000 visit requests per year), by ramping up its capacity for guided tours from 25,000 to more than 100,000 visitors per year, by creating six new of state-of-the-art exhibitions on-site, by building and operating a modern physics laboratory for school teachers and students, and by showing several traveling exhibitions in about 10 countries per year. The offer for school teachers has also been expanded, to 35-40 weeks of teacher courses with more than 1000 participants from more than 50 countries per year. The talk will give an overview about these and related activities.

  9. Fuel ethanol discussion paper

    International Nuclear Information System (INIS)

    1992-01-01

    In recognition of the potential benefits of ethanol and the merits of encouraging value-added agricultural development, a committee was formed to develop options for the role of the Ontario Ministry of Agriculture and Food in the further development of the ethanol industry in Ontario. A consultation with interested parties produced a discussion paper which begins with an outline of the role of ethanol as an alternative fuel. Ethanol issues which require industry consideration are presented, including the function of ethanol as a gasoline oxygenate or octane enhancer, environmental impacts, energy impacts, agricultural impacts, trade and fiscal implications, and regulation. The ethanol industry and distribution systems in Ontario are then described. The current industry consists of one ethanol plant and over 30 retail stations. The key issue for expanding the industry is the economics of producing ethanol. At present, production of ethanol in the short term depends on tax incentives amounting to 23.2 cents/l. In the longer term, a significant reduction in feedstock costs and a significant improvement in processing technology, or equally significant gasoline price increases, will be needed to create a sustainable ethanol industry that does not need incentives. Possible roles for the Ministry are identified, such as support for ethanol research and development, financial support for construction of ethanol plants, and active encouragement of market demand for ethanol-blended gasolines

    Fossil fuel depletion and the increase of greenhouse gases emissions has been pushing the search for alternative fuels for automotive transport. The European Union has identified biofuel technology as one option for reducing its dependence on imported energy. Ethanol is a promising biofuel, but great uncertainty on the business profitability has recently determined a slowdown in the industry expansion. In particular, geographical plant location, biomass price fluctuation and fuel demand variability severely constrain the economic viability of new ethanol facilities. In this work a dynamic, spatially explicit and multi-echelon Mixed Integer Linear Program (MILP) modeling framework is presented to help decision-makers and potential investors assessing economic performances and risk on investment of the entire biomass-based ethanol supply chain. A case study concerning the corn-to-ethanol production supply chain in Northern Italy is used to demonstrate the effectiveness of the proposed modeling approach. The mathematical pattern addresses the issue of optimizing the ethanol supply network over a ten years' time period under uncertainty on biomass production cost and product selling price. The model allows optimizing economic performances and minimize financial risk on investment by identifying the best network topology in terms of biomass cultivation site locations, ethanol production plant capacities, location and transport logistics. -- Highlights: →A dynamic spatially explicit Mixed Integer Linear Program (MILP) of the entire corn-based ethanol supply chain is proposed. →Uncertainty on corn price and ethanol selling price is taken into account. →The model allows assessing and optimizing the supply chain economic performance and risk on investment. →A case study concerning the corn-to-ethanol production in Northern Italy demonstrates the effectiveness of the approach.

    The objective of the proposed work is to develop an evaluation framework for NASA's educational outreach efforts. We focus on public (rather than technical or scientific) dissemination efforts, specifically on Internet-based outreach sites for children.The outcome of this work is to propose both methods and criteria for evaluation, which would enable NASA to do a more analytic evaluation of its outreach efforts. The proposed framework is based on IRL's ethnographic and video-based observational methods, which allow us to analyze how these sites are actually used.

    NASA's Juno spacecraft to the planet Jupiter was launched August 5, 2011, and went into a polar orbit about Jupiter on July 4, 2016. Besides the science, high level objectives of the Juno mission are outreach and citizen participation, which form the theme of this proposed talk. The outreach component includes a Power Point presentation, "Juno, The Cultural Connection," which briefly unveils the history, literature, music, art and visualization experiences that Juno embodies. This will include relating how its very name ties in profoundly with its scientific mission, through its embodiment of the literature of classical mythology and timeless masterpieces of the Renaissance and Baroque periods. In addition to the Power Point presentation, the model of the Juno orbital trajectory at Jupiter will be set up and displayed, configured for the day and time of the talk. The model was effectively displayed during the Fall AGU 2016. Citizen participation includes active involvement of attendees in proposing "Points of Interest" (POIs) on Jupiter for the Juno Camera to record images of. This will be accomplished through the Science in a Fishbowl program set up by Juno staff for this objective. After a brief tutorial on the Program, we will jointly select potential JunoCam POIs on Jupiter from an updated map of Jupiter projected on the screen, name them, and write brief rationales, generally one sentence, for why JunoCam should take pictures of the POIs. We will direct our attention to potential POIs that lie along the longitudes covered by JunoCam during its eleventh passage by Jupiter, referred to as Perijove 11 (PJ11), which will occur February 2, 2018. During a similar program at the International Multidisciplinary Scientific Geoconference (SGEM) 2017 held last summer in Albena, Bulgaria, we identified three POIs, named them, and wrote brief reasons why the selected POIs should be imaged by JunoCam. These named POIs were all in the JunoCam field of view during PJ8, which

    Undergraduate education incorporating active learning and vicarious experience through education outreach presents a critical opportunity to influence future engineering teaching and practice capabilities. Engineering education outreach activities have been shown to have multiple benefits; increasing interest and engagement with science and engineering for school children, providing teachers with expert contributions to engineering subject knowledge, and developing professional generic skills for engineers such as communication and teamwork. This pilot intervention paired 10 pre-service teachers and 11 student engineers to enact engineering outreach in primary schools, reaching 269 children. A longitudinal mixed methods design was employed to measure change in attitudes and Education Outreach Self-Efficacy in student engineers; alongside attitudes, Teaching Engineering Self-Efficacy and Engineering Subject Knowledge Confidence in pre-service teachers. Highly significant improvements were noted in the pre-service teachers' confidence and self-efficacy, while both the teachers and engineers qualitatively described benefits arising from the paired peer mentor model.

    The Large Synoptic Survey Telescope (LSST) will conduct a 10-year wide, fast, and deep survey of the night sky starting in 2022. LSST Education and Public Outreach (EPO) will enable public access to a subset of LSST data so anyone can explore the universe and be part of the discovery process. LSST EPO aims to facilitate a pathway from entry-level exploration of astronomical imagery to more sophisticated interaction with LSST data using tools similar to what professional astronomers use. To deliver data to the public, LSST EPO is creating an online Portal to serve as the main hub to EPO activities. The Portal will host an interactive Skyviewer, access to LSST data for educators and the public through online Jupyter notebooks, original multimedia for informal science centers and planetariums, and feature citizen science projects that use LSST data. LSST EPO will engage with the Chilean community through Spanish-language components of the Portal and will partner with organizations serving underrepresented groups in STEM.

    The ARES Directorate education team is charged with translating the work of ARES scientists into content that can be used in formal and informal K-12 education settings and assisting with public outreach. This is accomplished through local efforts and national partnerships. Local efforts include partnerships with universities, school districts, museums, and the Lunar and Planetary Institute (LPI) to share the content and excitement of space science research. Sharing astromaterials and exploration science with the public is an essential part of the Directorate's work. As a small enclave of physical scientists at a NASA Center that otherwise emphasizes human space operations and engineering, the ARES staff is frequently called upon by the JSC Public Affairs and Education offices to provide presentations and interviews. Scientists and staff actively volunteer with the JSC Speaker's Bureau, Digital Learning Network, and National Engineers Week programs as well as at Space Center Houston activities and events. The education team also participates in many JSC educator and student workshops, including the Pre-Service Teacher Institute and the Texas Aerospace Scholars program, with workshop presentations, speakers, and printed materials.

    As professional astronomer and science communicator, I want to share my personal experience communicating Astronomy and general science principles in maybe, the most popular science outreach devoted TV program in Cuba. It is broadcasted nationwide in a prime time schedule every Sunday. The Science Popularization on TV, is in a Third World Country hard to do if you want to produce attractive materials for a broad audience. Budgets constraints in most of the cases and lack of the technical equipment required to produce first class visual materials conspire, against motivation and creativity of local scientists and media professionals. A way to show the advance of the national scientific community in Science fields and connecting them in a friendly relation with a broad majority of the people, is to combine the wisdom and knowledge of the local scientists together with the most spectacular TV production of the first world countries. Commenting, analyzing and conveying the hard science into the public debate of the common citizens. Here is shown a way to convey cutting edge science to the general public, using limited resources to produce imaginative television productions, highlighting the development, knowledge and wisdom of the local scientists.

    This paper aims to describe funding models used and compare the effects of funding models for remuneration on clinical activity and cost-effectiveness in outreach eye services in Australia. Cross-sectional case study based in remote outreach ophthalmology services in Australia. Key stake-holders from eye services in nine outreach regions participated in the study. Semistructured interviews were conducted to perform a qualitative assessment of outreach eye services' funding mechanisms. Records of clinical activity were used to statistically compare funding models. Workforce availability (supply of ophthalmologists), costs of services, clinical activity (surgery and clinic consultation rates) and waiting times. The supply of ophthalmologists (full-time equivalence) to all remote regions was below the national average (up to 19 times lower). Cataract surgery rates were also below national averages (up to 10 times lower). Fee-for-service funding significantly increased clinical activity. There were also trends to shorter waiting times and lower costs per attendance. For outreach ophthalmology services, the funding model used for clinician reimbursement may influence the efficiency and costs of the services. Fee-for-service funding models, safety-net funding options or differential funding/incentives need further exploration to ensure isolated disadvantaged areas prone to poor patient attendance are not neglected. In order for outreach eye health services to be sustainable, remuneration rates need to be comparable to those for urban practice. © 2011 The Authors.

    Strategic use of oral toxicants could allow for practical and sustainable control schemes for the invasive common carp (Cyprinus carpio, or ‘carp’) if a toxicant selectively targeted carp and not native species. In this study, we incorporated antimycin-a (ANT-A), a known fish toxicant, into a corn-based bait and conducted a series of experiments to determine its toxicity, leaching rate, and species-specificity. Our results showed that ANT-A was lethal to carp at doses ≥ 4 mg/kg and that the amount of ANT-A that leached out of the bait in 72 h was not lethal to carp or bluegill (Lepomis macrochirus). Species-specificity trials were conducted in 227 L tanks, in which carp were stocked with three native species representing families that occur sympatrically with carp in our study region: the fathead minnow (Pimephales promelas), yellow perch (Perca flavescens) and bluegill. These trials showed high mortality of carp (46%) and fathead minnows (76%) but no significant mortality of perch or bluegill. Finally, a pond study, which used the same species composition except for fathead minnows, resulted in 37% morality among adult carp and no mortality among perch or bluegill. Our results suggest that corn-based bait that contains ANT-A could be used to selectively control carp in ecosystems dominated by percids or centrarchids, such as lakes across the Great Plains ecoregion of North America, where carp are especially problematic.

    2016-01-01

    The distribution of fumonisins (FBs: FB1 and FB2) in the corn-milling process and in corn-based products, as well as daily intake estimates for the Brazilian population were evaluated. Among corn fractions samples, corn meal had the highest mean concentration of FB1 (1305 µg kg(-1)) and FB2 (651 µg kg(-1)) and a distribution factors of 452% and 256% in relation to corn grain, respectively. On the other hand, the distribution factor of FB1 and FB2 in corn flour was found to be 144% and 88% respectively, which demonstrates that fumonisins in this fraction were reduced compared with corn grain. As a result, almost half the corn meal samples (47%) would be non-compliant with future Brazilian regulation (2017) for fumonisins. However, corn-based products, such as corn flakes and popcorn, were in compliance with the regulation. The average probable daily intake and maximum probable daily intake of fumonisins estimated for the Santa Catarina state (Brazil) population were below the provisional maximum tolerable daily intake of 2 µg kg(-1) body weight day(-1) for all corn samples. Despite this, the adoption of practices to control the occurrence of fumonisins should be applied to the corn-milling fractions that may contain a higher concentration of this toxin, such as corn meal, often used for animal feed in Brazil.

  3. Street outreach with no streets.

    2005-01-01

    A street nurse position in the rural and small-town interior of British Columbia has been addressing the needs of street-involved or otherwise marginalized client populations by bringing healthcare services to wherever those clients are, rather than waiting for the clients to seek care. The primary reason for a street outreach approach is that marginalized populations face a variety of barriers to accessing traditional healthcare services--barriers such as homelessness, mental health problems, criminal involvement, lack of transportation, lack of ability to pay for prescriptions, lack of specialized or knowledgeable providers and provider discrimination. In the rural street nurse program, the target population includes the usual street nurse populations of illegal drug users and sex trade workers, which are more hidden in small communities than in larger urban centres, creating the community denial that is a barrier to healthcare access. Yet another barrier is the co-locaton of services common in small communities, where public health clinics might share a building with police services, making marginalized clients reluctant to attend clinics. The rural street nurse collaborates with public health nurses and other care providers (mental health workers, social workers, etc) with collegial advice and support, making and receiving referrals, and generally assisting one another--the street nurse through his rapport with the marginalized individuals and the others with their specialized knowledge. Rural street services are delivered whereverthe clientsfeel comfortable: a school, a drop-in centre, a mall, a youth centre or simplythe street. Services provided include sexually transmitted infection testing, chlamydia treatments, pregnancy testing emergency contraception pills and assistance with filling out forms for financial support. Accordingly, the street nurse's truck is equipped as a mobile treatment centre and office, with a cellphone and a stock of testing and

    Full Text Available Insoluble fiber (IF recovered from the enzyme-assisted aqueous extraction process (EAEP of soybeans is a fraction rich in carbohydrates and proteins. It can be used to enhance ethanol production in an integrated corn-soy biorefinery, which combines EAEP with traditional corn-based ethanol processing. The present study evaluated IF as a substrate for ethanol production. The effects of treatment of IF (soaking in aqueous ammonia (SAA, liquid hot water (LHW, and enzymatic hydrolysis, primarily simultaneous saccharification and co-fermentation (SSCF, as well as scaling up (250 mL to 60 L on ethanol production from IF alone or a corn and IF slurry were investigated. Enzymatic hydrolysis (pectinase, cellulase, and xylanase, each added at 5% soy solids during simultaneous saccharification and fermentation/SSCF was the best treatment to maximize ethanol production from IF. Ethanol yield almost doubled when SSCF of IF was performed with Saccharomyces cerevisiae and Escherichia coli KO11. Addition of IF in dry-grind corn fermentation increased the ethanol production rate (~31%, but low ethanol tolerance of E. coli KO11 was a limiting factor for employing SSCF in combination corn and IF fermentation. Nonlinear Monod modeling accurately predicted the effect of ethanol concentration on E. coli KO11 growth kinetics by Hanes-Woolf linearization. Collectively, the results from this study suggest a potential of IF as a substrate, alone or in dry-grind corn fermentation, where it enhances the ethanol production rate. IF can be incorporated in the current bioethanol industry with no added capital investment, except enzymes.

    For the first 6 months of 2007, U.S. ethanol production totaled nearly 3 billion gallons—32 percent higher than the same period last year. As of August 29, there were 128 ethanol plants with annual production capacity totaling 6.78 billion gallons, and an additional 85 plants were under construction. U.S. ethanol production capacity is expanding rapidly and is currently expected to exceed 13 billion gallons per year by early 2009, if not sooner. Ethanol demand has increased corn prices and le...

    Students at Utah State University's College of Natural Resources have engineered the first mobile Earth Science outreach platform capable of delivering high-tech and interactive solar-powered educational resources to the traditionally-underserved, remote communities of rural Utah. By retrofitting and modifying an industrial box-truck, this project effectively created a highly mobile and energy independent "school in a box" which seeks to help change the way that Earth science is communicated, eliminate traditional barriers, and increase science accessibility - both physically and conceptually. The project's education platform is focused on developing a more effective, sustainable, and engaging platform for presenting Earth science outreach curricula to community members of all ages in an engaging fashion. Furthermore, this project affords university students the opportunity to demonstrate innovative science communication techniques, translating vital university research into educational outreach operations aimed at doing real, measurable good for local communities.

  8. Market penetration of ethanol

    International Nuclear Information System (INIS)

    Szulczyk, Kenneth R.; McCarl, Bruce A.; Cornforth, Gerald

    2010-01-01

    This research examines in detail the technology and economics of substituting ethanol for gasoline. This endeavor examines three issues. First, the benefits of ethanol/gasoline blends are examined, and then the technical problems of large-scale implementation of ethanol. Second, ethanol production possibilities are examined in detail from a variety of feedstocks and technologies. The feedstocks are the starch/sugar crops and crop residues, while the technologies are corn wet mill, dry grind, and lignocellulosic fermentation. Examining in detail the production possibilities allows the researchers to identity the extent of technological change, production costs, byproducts, and GHG emissions. Finally, a U.S. agricultural model, FASOMGHG, is updated which predicts the market penetration of ethanol given technological progress, variety of technologies and feedstocks, market interactions, energy prices, and GHG prices. FASOMGHG has several interesting results. First, gasoline prices have a small expansionary impact on the U.S. ethanol industry. Both agricultural producers' income and cost both increase with higher energy prices. If wholesale gasoline is $4 per gallon, the predicted ethanol market penetration attains 53% of U.S. gasoline consumption in 2030. Second, the corn wet mill remains an important industry for ethanol production, because this industry also produces corn oil, which could be converted to biodiesel. Third, GHG prices expand the ethanol industry. However, the GHG price expands the corn wet mill, but has an ambiguous impact on lignocellulosic ethanol. Feedstocks for lignocellulosic fermentation can also be burned with coal to generate electricity. Both industries are quite GHG efficient. Finally, U.S. government subsidies on biofuels have an expansionary impact on ethanol production, but may only increase market penetration by an additional 1% in 2030, which is approximately 6 billion gallons.

    Full Text Available Objective This trial was performed to examine the effects of ruminally degradable starch (RDS levels in total mixed ration (TMR with low corn-based starch on the milk production, whole-tract nutrient digestibility and nitrogen balance in dairy cows. Methods Eight multiparous Holstein cows (body weight [BW]: 717±63 kg; days in milk [DIM]: 169±29 were assigned to a crossover design with two dietary treatments: a diet containing 62.3% ruminally degradable starch (% of total starch, low RDS or 72.1% ruminally degradable starch (% of total starch, high RDS. Changes to the ruminally degradable levels were conducted by using either finely ground corn or steam-flaked corn as the starch component. Results The results showed that dry matter intake, milk yield and composition in dairy cows were not affected by dietary treatments. The concentration of milk urea nitrogen was lower for cows fed high RDS TMR than low RDS TMR. The whole-tract apparent digestibility of neutral detergent fiber, acid detergent fiber and crude protein decreased, and that of starch increased for cows fed high RDS TMR over those fed low RDS TMR, with no dietary effect on the whole-tract apparent digestibility of dry matter and organic matter. The proportion of urinary N excretion in N intake was lower and that of fecal N excretion in N intake was higher for cows fed high RDS TMR than those fed low RDS TMR. The N secretion in milk and the retention of N were not influenced by the dietary treatments. Total purine derivative was similar in cows fed high RDS TMR and low RDS TMR. Consequently, estimated microbial N flow to the duodenum was similar in cows fed high RDS TMR and low RDS TMR. Conclusion Results of this study show that ruminally degradable starch levels can influence whole-tract nutrient digestibility and nitrogen balance in dairy cows fed low corn-based starch diets, with no influence on performance.

    Full Text Available With an apparent increase of harmful algal blooms (HABs worldwide,healthcare providers, public health personnel and coastal managers are struggling toprovide scientifically-based appropriately-targeted HAB outreach and education. Since1998, the Florida Poison Information Center-Miami, with its 24 hour/365 day/year freeAquatic Toxins Hotline (1-888-232-8635 available in several languages, has received over 25,000 HAB-related calls. As part of HAB surveillance, all possible cases of HAB-relatedillness among callers are reported to the Florida Health Department. This pilot studyevaluated an automated call processing menu system that allows callers to access bilingualHAB information, and to speak directly with a trained Poison Information Specialist. Themajority (68% of callers reported satisfaction with the information, and many provided specific suggestions for improvement. This pilot study, the first known evaluation of use and satisfaction with HAB educational outreach materials, demonstrated that the automated system provided useful HAB-related information for the majority of callers, and decreased the routine informational call workload for the Poison Information Specialists, allowing them to focus on callers needing immediate assistance and their healthcare providers. These results will lead to improvement of this valuable HAB outreach, education and surveillance tool. Formal evaluation is recommended for future HAB outreach and educational materials.

  4. Satellite power system (SPS) public outreach experiment

    Energy Technology Data Exchange (ETDEWEB)

    McNeal, S.R.

    1980-12-01

    To improve the results of the Satellite Power System (SPS) Concept Development and Evaluation Program, an outreach experiment was conducted. Three public interest groups participated: the L-5 Society (L-5), Citizen's Energy Project (CEP), and the Forum for the Advancement of Students in Science and Technology (FASST). Each group disseminated summary information about SPS to approximately 3000 constituents with a request for feedback on the SPS concept. The objectives of the outreach were to (1) determine the areas of major concern relative to the SPS concept, and (2) gain experience with an outreach process for use in future public involvement. Due to the combined efforts of all three groups, 9200 individuals/organizations received information about the SPS concept. Over 1500 receipients of this information provided feedback. The response to the outreach effort was positive for all three groups, suggesting that the effort extended by the SPS Project Division to encourage an information exchange with the public was well received. The general response to the SPS differed with each group. The L-5 position is very much in favor of SPS; CEP is very much opposed and FASST is relatively neutral. The responses are analyzed, and from the responses some questions and answers about the satellite power system are presented in the appendix. (WHK)

  5. Science Outreach in Virtual Globes; Best Practices

    Science.gov (United States)

    Treves, R. W.

    2007-12-01

    The popularity of projects such as 'Crisis in Darfur' and the IPY (International Polar Year) network link show the potential of using the rich functionality of Virtual Globes for science outreach purposes. However, the structure of outreach projects in Virtual Globes varies widely. Consider an analogy: If you pick up a science journal you immediately know where to find the contents page and what the title and cover story are meant to communicate. That is because journals have a well defined set of norms that they follow in terms of layout and design. Currently, science projects presented in virtual globes have, at best, weakly defined norms, there are little common structural elements beyond those imposed by the constraints of the virtual globe system. This is not a criticism of the science community, it is to be expected since norms take time to develop for any new technology. An example of the development of norms are pages on the web: when they first started appearing structure was unguided but over the last few years structural elements such as a left hand side navigation system and a bread crumb trail near the header have become common. In this paper I shall describe the developing norms of structure I have observed in one area of virtual globe development; Google Earth science outreach projects. These norms include text introductions, video introductions, use of folders and overlay presentation. I shall go on to examine how best to use these norms to build a clear and engaging outreach project and describe some cartographic best practices that we should also consider adopting as norms. I also will briefly explain why I think norms in science outreach aid creativity rather than limiting it despite the counter intuitive nature of this concept.

  6. Outreach Testing of Ancient Astronomy

    Science.gov (United States)

    Sanmartin, J. R. S.; Blanco, M. B. M.

    2015-10-01

    This work is an outreach approach to an ubiquitous recent problem in secondary-school education: how to face back the decreasing interest in natural sciences shown by students under 'pressure' of convenient resources in digital devices/applications. The approach rests on two features. First, empowering of teen-age students to understand regular natural events around, as very few educated people they meet could do. Secondly, an understanding that rests on personal capability to test and verify experimental results from the oldest science, astronomy, with simple instruments as used from antiquity down to the Renaissance (a capability restricted to just solar and lunar motions). Because lengths in astronomy and daily life are so disparate, astronomy basically involved observing and registering values of angles (along with times), measurements being of two types, of angles on the ground and of angles in space, from the ground. First, the gnomon, a simple vertical stick introduced in Babylonia and Egypt, and then in Greece, is used to understand solar motion. The gnomon shadow turns around during any given day, varying in length and thus angle between solar ray and vertical as it turns, going through a minimum (noon time, at a meridian direction) while sweeping some angular range from sunrise to sunset. Further, the shadow minimum length varies through the year, with times when shortest and sun closest to vertical, at summer solstice, and times when longest, at winter solstice six months later. The extreme directions at sunset and sunrise correspond to the solstices, swept angular range greatest at summer, over 180 degrees, and the opposite at winter, with less daytime hours; in between, spring and fall equinoxes occur, marked by collinear shadow directions at sunrise and sunset. The gnomon allows students to determine, in addition to latitude (about 40.4° North at Madrid, say), the inclination of earth equator to plane of its orbit around the sun (ecliptic), this

  8. Environmental benefits of ethanol

    International Nuclear Information System (INIS)

    1998-11-01

    The environmental benefits of ethanol blended fuels in helping to reduce harmful emissions into the atmosphere are discussed. The use of oxygenated fuels such as ethanol is one way of addressing air pollution concerns such as ozone formation. The state of California has legislated stringent automobile emissions standards in an effort to reduce emissions that contribute to the formation of ground-level ozone. Several Canadian cities also record similar hazardous exposures to carbon monoxide, particularly in fall and winter. Using oxygenated fuels such as ethanol, is one way of addressing the issue of air pollution. The net effect of ethanol use is an overall decrease in ozone formation. For example, use of a 10 per cent ethanol blend results in a 25-30 per cent reduction in carbon monoxide emissions by promoting a more complete combustion of the fuel. It also results in a 6-10 per cent reduction of carbon dioxide, and a seven per cent overall decrease in exhaust VOCs (volatile organic compounds). The environmental implications of feedstock production associated with the production of ethanol for fuel was also discussed. One of the Canadian government's initiatives to address the climate change challenge is its FleetWise initiative, in which it has agreed to a phased-in acquisition of alternative fuel vehicles by the year 2005. 9 refs

    2015-08-01

    In its strategic planning for the "Astronomy for Development Project," the International Astronomical Union (IAU) has ecognized, among other important missions, the role of astronomy in understanding the far-reaching possibilities for promoting global tolerance and citizenship. Furthermore, astronomy is deemed inspirational for careers in science and technology. The "Pilot Astronomy Outreach Project in Bangladesh"--the first of its kind in the country--aspires to fulfill these missions. As Bangladesh lacks resources to promote astronomy education in universities and schools, the role of disseminating astronomy education to the greater community falls on citizen science organizations. One such group, Anushandhitshu Chokro (AChokro) Science Organization, has been carrying out a successful public outreach program since 1975. Among its documented public events, AChokro organized a total solar eclipse campaign in Bangladesh in 2009, at which 15,000 people were assembled in a single open venue for the eclipse observation. The organization has actively pursued astronomy outreach to dispel public misconceptions about astronomical phenomena and to promote science. AChokro is currently working to build an observatory and Science Outreach Center around a recently-acquired 14-inch Scmidt-Cassegrain telescope and a soon-to-be-acquired new 16-inch reflector, all funded by private donations. The telescopes will be fitted with photometers, spectrometers, and digital and CCD cameras to pursue observations that would include sun spot and solar magnetic fields, planetary surfaces, asteroid search, variable stars and supernovae. The Center will be integrated with schools, colleges, and community groups for regular observation and small-scale research. Special educational and observing sessions for adults will also be organized. Updates on the development of the Center, which is expected to be functioning by the end of 2015, will be shared and feedback invited on the fostering of

  13. Competitiveness of Brazilian sugarcane ethanol compared to US corn ethanol

    International Nuclear Information System (INIS)

    Crago, Christine L.; Khanna, Madhu; Barton, Jason; Giuliani, Eduardo; Amaral, Weber

    2010-01-01

    Corn ethanol produced in the US and sugarcane ethanol produced in Brazil are the world's leading sources of biofuel. Current US biofuel policies create both incentives and constraints for the import of ethanol from Brazil and together with the cost competitiveness and greenhouse gas intensity of sugarcane ethanol compared to corn ethanol will determine the extent of these imports. This study analyzes the supply-side determinants of cost competitiveness and compares the greenhouse gas intensity of corn ethanol and sugarcane ethanol delivered to US ports. We find that while the cost of sugarcane ethanol production in Brazil is lower than that of corn ethanol in the US, the inclusion of transportation costs for the former and co-product credits for the latter changes their relative competitiveness. We also find that the relative cost of ethanol in the US and Brazil is highly sensitive to the prevailing exchange rate and prices of feedstocks. At an exchange rate of US1=R2.15 the cost of corn ethanol is 15% lower than the delivered cost of sugarcane ethanol at a US port. Sugarcane ethanol has lower GHG emissions than corn ethanol but a price of over $113 per ton of CO 2 is needed to affect competitiveness. (author)

    2008-12-01

    Many scientists are studying the Sun-Earth system and attempting to provide timely, accurate, and reliable space environment observations and forecasts. Research programs and missions serve as an ideal focal point for creating educational content, making this an ideal time to inform the public about the importance and value of space weather research. In order to take advantage of this opportunity, the Space Science Institute (SSI) is developing a comprehensive Space Weather Outreach program to reach students, educators, and other members of the public, and share with them the exciting discoveries from this important scientific discipline. The Space Weather Outreach program has the following five components: (1) the Space Weather Center Website that includes online educational games; (2) Small Exhibits for Libraries, Shopping Malls, and Science Centers; (3) After-School Programs; (4) Professional Development Workshops for Educators, and (5) an innovative Evaluation and Education Research project. Its overarching goal is to inspire, engage, and educate a broad spectrum of the public and make strategic and innovative connections between informal and K-12 education communities. An important factor in the success of this program will be its alignment with STEM standards especially those related to science and mathematics. This presentation will describe the Space Weather Outreach program and how standards are being used in the development of each of its components.

  15. Outreach: Key to Sustainable Nuclear Knowledge Management

    International Nuclear Information System (INIS)

    Segovia, V.

    2016-01-01

    Full text: With the numerous nuclear power plants being built globally and the prospects for many more, the challenge of the timely availability of a well-prepared, qualified, knowledgeable workforce is a key element in the “critical path” to commissioning these plants. All of these individuals will need quality education and training that is rooted in safety and established in experience. In addition, because many of these new plants are typically being built in developing countries, education, training, recruiting and retaining operations staff can be a significant challenge. Attracting sources of qualified employees for these nuclear power plants in local communities is paramount which implies a strong focus on the science and math education outreach programmes at all levels. This paper will highlight the Nuclear Power Institute’s integration of human resource development outreach strategies, education and training systems, and international cooperation to demonstrate how working in particular with the education sector can not only create interest in future careers in nuclear technology and capture valuable knowledge, but can also build community based support for nuclear power programmes with an emphasis of developing competent workers through education and training, mentoring and apprenticeships. Outreach has also become an important element of all nuclear knowledge management endeavours. (author

    2001-01-01

    Experts from the Nordic countries (Denmark, Norway, Sweden, Finland and Iceland) have carried out an evaluation of fumonisins. The working group members concluded that, at that time point, it was not possible to carry out a complete risk assessment. However, it was recommended that the human daily...... intake of fumonisins should be less than 1 mug/kg bw/day. Subsequently, the presence of the Fusarium mycotoxins fumonisin B-1 and B-2 (FB1 and FB2) in corn-based food on the Danish retail market has been determined. A total of 70 samples were analysed and 37% contained FB1 and 21% contained FB2....... No fumonisins were found in sweet corn (canned or frozen), corn-on-the-cob, corn starch or gruel powder for babies. FB1 was found in about half of the corn flakes, corn snack and popcorn (not popped) samples, whereas FB2 was seen to a lesser extent. Both FB1 and FB2 were found in 75% or more of the corn flour...

    1993-01-01

    The largest alternative transportation fuels program in the world today is Brazil's Proalcool Program. About 6.0 million metric tons of oil equivalent (MTOE) of ethanol, derived mainly from sugar cane, were consumed as transportation fuels in 1991 (equivalent to 127,000 barrels of crude oil per day). Total primary energy consumed by the Brazilian economy in 1991 was 184.1 million MTOE, and approximately 4.3 million vehicles -- about one third of the total vehicle fleet or about 40 percent of the total car population -- run on hydrous or open-quotes neatclose quotes ethanol at the azeotropic composition (96 percent ethanol, 4 percent water, by volume). Additional transportation fuels available in the country are diesel and gasoline, the latter of which is defined by three grades. Gasoline A (regular, leaded gas)d has virtually been replaced by gasoline C, a blend of gasoline and up to 22 percent anhydrous ethanol by volume, and gasoline B (premium gasoline) has been discontinued as a result of neat ethanol market penetration

    2004-12-01

    ``I'm a scientist who knows how to conduct research, not an expert in teaching pre-college students!'' is a common complaint within the scientific community in response to recent funding agency mandates that research proposals explicitly address education, public outreach or other broader impacts. Yet, these new requirements address several important goals - fostering public support for research funding in the Earth and Space sciences, recruiting the next generation of talented geoscientists in the face of declining student enrollments, and educating the citizenry for informed decision making and advocacy, chief among them. Further, the phrase ``broader impacts'' is not meant to be synonymous with outreach to pre-college students and teachers - agency program managers actually encourage many different types of activity for meeting these obligations. AGU and its Committee on Education and Human Resources (CEHR) are committed to offering an array of programs that facilitate our members' ability to meet these new education, outreach, and broader impacts criteria in support of the research enterprise. CEHR has an on-going need for scientists willing to speak about their research in Geophysical Information for Teacher (GIFT) Workshops, sponsored lectures at annual and regional conventions of the National Science Teachers Association, special symposia for minority high school students attending annual AGU meetings, and career planning workshops for students and early career investigators. More extensive involvement as meeting mentors for minority undergraduate and graduate students is available through AGU's partnership with the new MSPHDS initiative (A. Pyrtle, P.I.). A new AGU outreach web site now under development will make available scientist biographies and abstracts derived from recent scientific articles originally published in AGU journals, which have been rewritten for a public audience. This resource is expected to serve as an important vehicle for AGU members

  4. Implications of increased ethanol production

    International Nuclear Information System (INIS)

    1992-06-01

    The implications of increased ethanol production in Canada, assuming a 10% market penetration of a 10% ethanol/gasoline blend, are evaluated. Issues considered in the analysis include the provision of new markets for agricultural products, environmental sustainability, energy security, contribution to global warming, potential government cost (subsidies), alternative options to ethanol, energy efficiency, impacts on soil and water of ethanol crop production, and acceptance by fuel marketers. An economic analysis confirms that ethanol production from a stand-alone plant is not economic at current energy values. However, integration of ethanol production with a feedlot lowers the break-even price of ethanol by about 35 cents/l, and even further reductions could be achieved as technology to utilize lignocellulosic feedstock is commercialized. Ethanol production could have a positive impact on farm income, increasing cash receipts to grain farmers up to $53 million. The environmental impact of ethanol production from grain would be similar to that from crop production in general. Some concerns about ethanol/gasoline blends from the fuel industry have been reduced as those blends are now becoming recommended in some automotive warranties. However, the concerns of the larger fuel distributors are a serious constraint on an expansion of ethanol use. The economics of ethanol use could be improved by extending the federal excise tax exemption now available for pure alcohol fuels to the alcohol portion of alcohol/gasoline blends. 9 refs., 10 tabs

    Ethanol abuse can lead to negative consequences that oftentimes result in criminal charges and civil lawsuits. When an individual is suspected of driving under the influence, law enforcement agents can determine the extent of intoxication by measuring the blood alcohol concentration (BAC) and performing a standardized field sobriety test. The BAC is dependent on rates of absorption, distribution, and elimination, which are influenced mostly by the dose of ethanol ingested and rate of consumption. Other factors contributing to BAC are gender, body mass and composition, food effects, type of alcohol, and chronic alcohol exposure. Because of individual variability in ethanol pharmacology and toxicology, careful extrapolation and interpretation of the BAC is needed, to justify an arrest and assignment of criminal liability. This review provides a summary of the pharmacokinetic properties of ethanol and the clinical effects of acute intoxication as they relate to common forensic questions. Concerns regarding the extrapolation of BAC and the implications of impaired memory caused by alcohol-induced blackouts are discussed. © 2017 American Academy of Psychiatry and the Law.

    , there is not enough biomass for 'everyone', not physically and not in terms of money to promote its use. This leads to the conclusion that any use of biomass for energy purposes will have to compare to the lost opportunity of using it for something else. In this perspective, the choice to use biomass for bio......-ethanol production will not lead to reduction but to increase in CO2 emission and fossil fuel dependency. Both first and second generation bio-ethanol suffer from a biomass-to-ethanol energy conversion efficiency as low as 30-40 %, and moreover external fossil fuels are used to run the conversion. There is only......, but they do not improve the energy balance enough for bio-ethanol to compete with alternative uses of the biomass. When using biomass to substitute fossil fuels in heat & power production, a close to 100% substitution efficiency is achieved. The best alternative for CO2 reduction and oil saving is, therefore...

    The ATLAS Education and Outreach (E&O) program began in 1997, but the advent of LHC has placed a new urgency in our efforts. Even a year away, we can feel the approaching impact of starting an experiment that could make revolutionary discoveries. The public and teachers are beginning to turn their attention our way, and the newsmedia are showing growing interest in ATLAS. When datataking begins, the interest will peak, and the demands on us are likely to be substantial. The collaboration is responding to this challenge in a number of ways. ATLAS management has begun consultation with experts. The official budget for the E&O group has been growing as have the contributions of many ATLAS institutions. The number of collaboration members joining these efforts has grown, and their time and effort is increasing. We are in ongoing consultation with the CERN Public Affairs Office, as well as the other LHC experiments and the European Particle Physics Outreach Group. The E&O group has expanded the scope...

    The Greater Sekhukhune-CAPABILITY Outreach Project was undertaken in a rural district in Limpopo, South Africa, as part of the European Union-funded CAPABILITY programme to investigate approaches for capacity building for the translation of genetic knowledge into care and prevention of congenital disorders. Based on previous experience of a clinical genetic outreach programme in Limpopo, it aimed to initiate a district clinical genetic service in Greater Sekhukhune to gain knowledge and experience to assist in the implementation and development of medical genetic services in South Africa. Implementing the service in Greater Sekhukhune was impeded by a developing staff shortage in the province and pressure on the health service from the existing HIV/AIDS and TB epidemics. This situation underscores the need for health needs assessment for developing services for the care and prevention of congenital disorders in middle- and low-income countries. However, these impediments stimulated the pioneering of innovate ways to offer medical genetic services in these circumstances, including tele-teaching of nurses and doctors, using cellular phones to enhance clinical care and adapting and assessing the clinical utility of a laboratory test, QF-PCR, for use in the local circumstances.

    The development of a robust source of renewable transportation fuel will require a large amount of biomass feedstocks. It is generally accepted that in addition to agricultural and forestry residues, we will need crops grown specifically for subsequent conversion into fuels. There has been a lot of research on several of these so-called "dedicated bioenergy crops" including switchgrass, miscanthus, sugarcane, and poplar. It is likely that all of these crops will end up playing a role as feedstocks, depending on local environmental and market conditions. Many different types of sorghum have been grown to produce syrup, grain, and animal feed for many years. It has several features that may make it as compelling as other crops mentioned above as a renewable, sustainable biomass feedstock; however, very little work has been done to investigate sorghum as a dedicated bioenergy crop. The goal of this project was to investigate the feasibility of using sorghum biomass to produce ethanol. The work performed included a detailed examination of the agronomics and composition of a large number of sorghum varieties, laboratory experiments to convert sorghum to ethanol, and economic and life-cycle analyses of the sorghum-to-ethanol process. This work showed that sorghum has a very wide range of composition, which depended on the specific sorghum cultivar as well as the growing conditions. The results of laboratory- and pilot-scale experiments indicated that a typical high-biomass sorghum variety performed very similarly to corn stover during the multi-step process required to convert biomass feedstocks to ethanol; yields of ethanol for sorghum were very similar to the corn stover used as a control in these experiments. Based on multi-year agronomic data and theoretical ethanol production, sorghum can achieve more than 1,300 gallons of ethanol per acre given the correct genetics and environment. In summary, sorghum may be a compelling dedicated bioenergy crop that could help

    With a general decline in people's choosing to pursue science and engineering degrees there has never been a greater need to raise the awareness of lesser known fields such as acoustics. Given this context, a large-scale public engagement project, the 'Aeolus project', was created to raise awareness of acoustics science through a major collaboration between an acclaimed artist and acoustics researchers. It centred on touring the large singing sculpture Aeolus during 2011/12, though the project also included an extensive outreach programme of talks, exhibitions, community workshops and resources for schools. Described here are the motivations behind the project and the artwork itself, the ways in which scientists and an artist collaborated, and the public engagement activities designed as part of the project. Evaluation results suggest that the project achieved its goal of inspiring interest in the discipline of acoustics through the exploration of an other-worldly work of art. © The Author(s) 2013.

    The Hear and See methodology has often been used as a means of enhancing pedagogy by focusing on the two strongest learning senses, but this naturally does not apply to deaf or hard of hearing students. Because deaf students' prior nonaural experiences with sound will vary significantly from those of students with typical hearing, different methods must be used to build understanding. However, the sensory-focused pedagogical principle can be applied in a different way for the Deaf by utilizing the senses of touch and sight, called here the ``See and Feel'' method. This presentation will provide several examples of how acoustics demonstrations have been adapted to create an outreach program for a group of junior high students from a school for the Deaf and discuss challenges encountered.

    Athabasca University's AUTUMNX ground-based magnetometer array to measure and report geomagnetic conditions in eastern Canada is located in the heart of French speaking Canada. Through the course of the project, we have had the privilege to partner with schools, universities, astronomy clubs and government agencies across Quebec, all of which operate primarily in French. To acknowledge and serve the needs of our research partners, we have endeavored to produce educational and outreach (EPO) material adapted for francophone audiences with the help of UCLA's department of Earth, Planetary and Space Sciences (EPSS). Not only will this provide greater understanding and appreciation of the geospace environment unique to Quebec and surrounding regions, it strengthens our ties with our francophone, first nations (native Americans) and Inuit partners, trailblazing new paths of research collaboration and inspiring future generations of researchers.

    2015-12-01

    Since the Cambridge Science Festival launched in 2007, communities across the United States have experimented with the science festival format, working out what it means to celebrate science and technology. What have we learned, and where might we go from here? The Science Festival Alliance has supported and tracked developments among U.S. festivals, and this presentation will present key findings from three years of independent evaluation. While science festivals have coalesced into a distinct category of outreach activity, the diversity of science festival initiatives reflects the unique character of the regions in which the festivals are organized. This symposium will consider how festivals generate innovative public programming by adapting to local conditions and spur further innovation by sharing insights into such adaptations with other festivals. With over 55 annual large scale science festivals in the US alone, we will discuss the implications of a dramatic increase in future festival activity.

    An experiment was conducted to determine the effects of dietary starch content in corn-based diets and corn particle size on lactation performance, nutrient digestibility, and bacterial protein flow in dairy cows using the omasal and reticular sampling technique. Eight ruminally cannulated lactating multiparous Holstein cows were used in a replicated 4×4 Latin square design with a 2×2 factorial arrangement of treatments. Treatments were fine (FG; mean particle size=552µm) and coarse (CG; 1,270µm) ground dry shelled corn in normal- (NS) and reduced- (RS) starch diets fed as total mixed rations. The NS and RS rations contained 27 and 18% starch (dry matter basis), respectively, and were formulated by partially replacing corn with soy hull pellets. Mean dry matter intake was unaffected by treatment (23.2kg/d). Cows fed NS diets produced 1.9kg/d more milk and 0.06kg/d more milk protein compared with cows fed RS diets. Cows fed NSFG and RSCG diets produced more fat-corrected milk than did cows fed NSCG and RSFG diets. Milk urea concentration was decreased for cows fed NS diets (12.4mg/dL) compared with RS diets (13.5mg/dL). Ruminal digestibility of neutral detergent fiber (NDF; % of NDF intake) determined by the omasal sampling technique was increased in cows fed RS diets compared with NS diets (43.4 vs. 34.9%), and total-tract digestibility of NDF (% of NDF intake) was increased in cows fed RS diets compared with those fed NS diets (50.1 vs. 43.1%). Ruminal digestibility of starch (% of starch intake) determined by the omasal sampling technique was greater in cows fed NS diets compared with those fed RS diets (85.6 vs. 81.6%). Total-tract starch digestion was increased in cows fed RS diets compared with those fed NS diets (96.9 vs. 94.6%) and in cows fed FG diets compared with those fed CG diets (98.0 vs. 93.5%). Bacterial protein flow was unaffected by treatment. The omasal and reticular sampling techniques resulted in similar treatment effects for nutrient flow

    An experiment was conducted to evaluate the effects of corn-based dietary starch content and source of neutral detergent fiber (NDF) on lactation performance, nutrient digestion, bacterial protein flow, and ruminal parameters in lactating dairy cows. Eight ruminally cannulated multiparous Holstein cows averaging 193±11d in milk were randomly assigned to treatments in a replicated 4×4 Latin square design with 21-d periods. Treatment diets were high corn grain (HCG; 38% corn silage, 19% dry ground corn, and 4% soy hulls), high soy hulls (HSH; 38% corn silage, 11% dry ground corn, and 13% soy hulls), high corn silage (HCS; 50% corn silage, 6% dry ground corn, and 4% soy hulls), and low corn silage (LCS; 29% corn silage, 15% corn, and 19% soy hulls). The HCG, HSH, HCS, and LCS diets contained 29, 23, 24, and 22% starch; 27, 32, 30, and 32% total NDF; and 21, 21, 25, and 17% forage NDF (dry matter basis), respectively. Mean dry matter intake and milk yield were unaffected by treatment. Cows fed LCS had reduced milk fat content compared with HSH and HCS. The concentration of milk urea nitrogen was greater for cows fed HCS compared with the other treatments. Total-tract digestion of NDF was reduced for cows fed the HCG diet. Total-tract starch digestion was increased for cows fed the HSH and HCS compared with HCG and LCS diets. Bacterial protein flow was unaffected by treatment. Ruminal ammonia concentration was reduced in cows fed the HCG and LCS diets compared with the HCS diet. Ruminal propionate increased and the acetate:propionate ratio decreased in cows fed the LCS diet compared with the HCS diet. Ruminal pH was greater for cows fed the HCS diet compared with cows fed the LCS diet. Diet digestibility and performance of mid- to late-lactation cows fed reduced-starch diets by partially replacing corn grain with soy hulls or corn silage was similar to or improved compared with cows fed a normal-starch diet.

  4. An applied investigation of corn-based distillers dried grains with solubles in the production of natural fiber-plastic composites

    Castillo, Hugo Eudosio

    The main objective of this research was to examine uses for distillers dried grains with solubles (DDGS), a coproduct of ethanol production plant, in the fiber-reinforced plastic composites industry. Initially the effort intended to take advantage of the DDGS components, using chemical reactions, to produce coupling agents to improve the physical properties of the composite. Four different chemicals plus water were used to convert proteins into soluble amino acids. The results were not as expected, and appeared to show an early pyrolysis of DDGS components. This may be due to regeneration of proteins when pH of solutions is neutralized. Procedures were then investigated to utilize DDGS for different markets. Considering that oils and proteins of DDGS can thermally decompose, it seemed important to separate the major components and work with DDGS fiber alone. A procedure to extract oil from DDGS using ethanol and then to hydrolyze proteins with ethanol diluted with water, acid and sodium sulfite, was developed. The resulting DDGS fiber or residual material, with a low content of oil and proteins, was used as filler in a propylene matrix with a lubricant and coupling agent to make natural fiber plastic composites (NFPC). Composites containing wood flour (WPC) were prepared simultaneously with those of DDGS fiber to compare tensile properties and fracture surfaces of the specimens by scanning electron microscope (SEM). This study demonstrates that DDGS fiber can replace wood fiber as a filler in NFPC.

    In an effort to reduce the incidence of childhood obesity, the National Aeronautics and Space Administration (NASA), capitalizing on the theme of human spaceflight developed two educational outreach programs for children ages 8-12. To motivate young "fit explorers," the Train Like an Astronaut National (TLA) program and the Mission X: Train Like an Astronaut International Fitness Challenge (MX) were created. Based on the astronauts' physical training, these programs consist of activities developed by educators and experts in the areas of space life sciences and fitness. These Activities address components of physical fitness. The educational content hopes to promote students to pursue careers in science, technology, engineering, and math (STEM) fields. At the national level, in partnership with First Lady Michelle Obama's Let?s Move! Initiative, the TLA program consists of 10 physical and 2 educational activities. The program encourages families, schools, and communities to work collaboratively in order to reinforce in children and their families the importance of healthy lifestyle habits In contrast, the MX challenge is a cooperative outreach program involving numerous space agencies and other international partner institutions. During the six-week period, teams of students from around the world are challenged to improve their physical fitness and collectively accumulate points by completing 18 core activities. During the 2011 pilot year, a t otal of 137 teams and more than 4,000 students from 12 countries participated in the event. MX will be implemented within 24 countries during the 2012 challenge. It is projected that 7,000 children will "train like an astronaut".

    Did you know... that the writing on the bathroom wall isn't just graffiti anymore? Studies have shown that messages in unusual locations can have extraordinary impact. A growing number of companies and non-profit organizations are placing signage in unexpected venues, such as bathroom stalls, sporting arena seatbacks, gas stations, and diaper-changing areas. A 2003 study found that public response to promotional materials posted in restrooms was overwhelmingly positive, and respondents view these materials for up to two minutes instead of the 3 to 5 seconds they spend with traditional print marketing. Recall rates of content and messages are high, and researchers found bathroom signage to be 40% more effective than a typical print sign. It is often difficult to design effective education and outreach programs that reach a broader audience than a fairly self-selective one. Most of our events and projects ask audiences to come to us. This format inherently attracts a science-interested audience. So how do you reach the other half, those non-traditional learners, in an effective manner? Take the science to them! Help your message be more effective by "shocking” them with the science. Placing science, technology, engineering, and mathematical (STEM) content in unexpected venues makes it accessible, memorable, and likely to reach a captive audience that might not otherwise seek it out. The "Did You Know?” campaign brings STEM messages to underserved audiences through innovative placement. Bathroom stalls, movie theaters, and shopping malls are visited by thousands each day and provide a surprising and overlooked venue for outreach.

    2014-05-01

    While rats have been predominantly used to study operant ethanol self-administration behavior in the context of dependence, several studies have employed operant conditioning procedures to examine changes in ethanol self-administration behavior as a function of chronic ethanol exposure and withdrawal experience in mice. This review highlights some of the advantages of using operant conditioning procedures for examining the motivational effects of ethanol in animals with a history of dependence. As reported in rats, studies using various operant conditioning procedures in mice have demonstrated significant escalation of ethanol self-administration behavior in mice rendered dependent via forced chronic ethanol exposure in comparison to nondependent mice. This paper also presents a summary of these findings, as well as suggestions for future studies. Copyright © 2014 Elsevier Inc. All rights reserved.

  8. Production of ethanol

    Energy Technology Data Exchange (ETDEWEB)

    1981-10-10

    Ethanol is produced by fermentation with a photohardening resin-immobilized yeast preparation. The ethanol producing yeast may be selected from Saccharomyces, Zygosaccharomyces, or Schizosaccharomyces. The photohardening resin for yeast immobilization is a hydrophilic unsaturated compound, especially polyurethane acrylate, with an average molecular weight of 300-80,000 and containing at least 2 photopolymerizable ethylene groups. The immobilized yeast preparation is prepared by irradiating an aqueous suspension of yeast and a photohardening resin with UV light; the average size of the immobilized yeast is 0.1-3.0 mm and with various shapes. Thus, an aqueous suspension containing Saccharomyces formosensis cells (5 parts), a poly(ethylene glycol)isopharone diisocyanate-2-hydroxyethyl methacrylate copolymer (50 parts), and benzoin ethyl ether (0.5 parts) was homogenized, spread on a polypropylene tray (1.0 mm depth), and irradiated with a 3600 A Hg lamp for 5-10 minutes to form a yeast-containing polyurethane acrylate sheet (1.0 mm thickness), which was then sliced into bits of approximately 1.0 mm. When a molasses substrate solution (pH 4.5-5.0) was passed through a column (200 x 20 mm) packed with the polyurethane acrylate-immobilized yeast preparation, eluates containing 7% (weight/volume) ethanol were produced for >3000 hours.

  9. Innovative inexpensive ethanol

    New Energy Company of Indiana which produces 70 million gallons of ethanol per year, avoids the headaches often associated with organic by-products by creating an efficient and profitable sideline business. This paper reports that stretching across 55 acres in South Bend, Ind., New Energy's plant is the largest in the U.S. built specifically for fuel alcohol. The $186-million complex is a dramatic advance in the art of producing ethanol and its co-products. As the demand grows in the coming years for fuel alcohol-proven as an octane booster and a clean-burning alternative fuel. New Energy looks forward to increase production and profits. At the company's six-year-old plant, fuel alcohol is made from 26 million bushels a year of No. 2 yellow dent corn. Left at the bottom of the first column, after the alcohol has been boiled off, is stillage that contains more than 90% of the corn's protein and fat content, and virtually all of its vitamins and minerals, along with the yeast used to make the ethanol. While technically a waste product of the fuel alcohol process, this material's quantity and organic content not only make it difficult and costly to dispose, but its nutritional quality makes it an excellent candidate to be further processed into animal feed

  10. Xylose fermentation to ethanol

    1993-01-01

    The past several years have seen tremendous progress in the understanding of xylose metabolism and in the identification, characterization, and development of strains with improved xylose fermentation characteristics. A survey of the numerous microorganisms capable of directly fermenting xylose to ethanol indicates that wild-type yeast and recombinant bacteria offer the best overall performance in terms of high yield, final ethanol concentration, and volumetric productivity. The best performing bacteria, yeast, and fungi can achieve yields greater than 0.4 g/g and final ethanol concentrations approaching 5%. Productivities remain low for most yeast and particularly for fungi, but volumetric productivities exceeding 1.0 g/L-h have been reported for xylose-fermenting bacteria. In terms of wild-type microorganisms, strains of the yeast Pichia stipitis show the most promise in the short term for direct high-yield fermentation of xylose without byproduct formation. Of the recombinant xylose-fermenting microorganisms developed, recombinant E. coli ATTC 11303 (pLOI297) exhibits the most favorable performance characteristics reported to date.

  11. Fact sheet: Ethanol from corn

    1999-05-31

    This fact sheet is intended to provide an overview of the advantages of ethanol from corn, emphasizing ethanol`s contribution to environmental protection and sustainable agriculture. Ethanol, an alternative fuel used as an octane enhancer is produced through the conversion of starch to sugars by enzymes, and fermentation of these sugars to ethanol by yeast. The production process may involve wet milling or dry milling. Both these processes produce valuable by-products, in addition to ethanol and carbon dioxide. Ethanol contains about 32,000 BTU per litre. It is commonly believed that using state-of-the-art corn farming and corn processing processes, the amount of energy contained in ethanol and its by-products would be more than twice the energy required to grow and process corn into ethanol. Ethanol represents the third largest market for Ontario corn, after direct use as animal feed and wet milling for starch, corn sweetener and corn oil. The environmental consequences of using ethanol are very significant. It is estimated that a 10 per cent ethanol blend in gasoline would result in a 25 to 30 per cent decrease in carbon monoxide emissions, a 6 to 10 per cent decrease in net carbon dioxide, a slight increase in nitrous oxide emissions which, however, would still result in an overall decrease in ozone formation, since the significant reduction in carbon monoxide emissions would compensate for any slight increase in nitrous oxide. Volatile organic compounds emission would also decrease by about 7 per cent with a 10 per cent ethanol blend. High level blends could reduce VOCs production by as much as 30 per cent. 7 refs.

    As cities around the world grow more and more diverse, we must take this diversity into account in developing outreach activities and materials. The International Year of Astronomy in 2009 brought a lot of attention to the needs of underserved communities and developing countries, emphasizing the ideal of widespread access to astronomy outreach. Increasingly, however, we find that some of the same challenges facing underserved communities and developing countries are also present in modern metropolises. Conveniently, the linguistic and cultural diversity of our cities is more and more accurately reflected among the astronomy community. The diversity of the astronomical community itself creates opportunities for effective multicultural, multilingual outreach.

    India is involved in a major way in both the aspects, i.e. scientific as well as outreach activities, of the International Polar Year (IPY) 2007-2008. National Centre for Antarctic & Ocean Research (NCAOR, under the Ministry of Earth Sciences, Government of India) is acting as the national coordinating agency. The launching of the Indian chapter of the IPY 2007-2008 took place at NCAOR and parallely at Jawaharlal Nehru National University (JNU), New Delhi on 1st March 2007. Two Indian scientific proposals have been endorsed by IPY, which are Project id. 70 and Project id. 129. Simultaneously, India is actively involved in the outreach activities related to IPY. NCAOR had sponsored the visit of two college students to Antarctica during the 25th Indian Antarctic Expedition (IAE). A series of lectures were delivered by one of them at more than twenty schools & colleges in the rural & suburban areas of Indian state of Maharashtra regarding the wonders of Antarctica to educate the general public and popularize polar science. NCAOR is the only Indian institute that has the capability to store and sample Antarctic ice core with special Cold Room facility that is maintained at -20°C. Students from several schools and colleges and scientists/visitors from various Indian institutes/foreign countries have visited NCAOR to get first hand experience of polar research. NCAOR has also collaborated with WWF-India (World Wide Fund for Nature) for carrying out the outreach activities to schools throughout the vast expanses of India. In this regard a calendar of event was released on 1st March 2007, which lists various competitions and activities that will be held during 2007-2008. It includes competitions such as poster & model making, stamp designing, petition writing etc. for school children. The first competition, poster making & slogan writing, was held at New Delhi on April 10, 2007 and prizes were distributed by the H'ble Minister of Science & Technology and Earth Sciences on

    1992-01-01

    In recent years, the University of Missouri-Rolla Reactor (UMRR) facility has been under intense financial scrutiny by the university administration; primarily due to ever-tightening budgets and declines in nuclear engineering (NE) enrollment. In response to criticisms of low utilization, the reactor staff has developed and implemented a dynamic outreach program designed to significantly increase the educational role of the facility on campus. The outreach program is based on the principle that the potential to provide service to the UMR community is far in excess of the present level of service. The program is designed to identify and inform potential users of how their courses or programs can be augmented through use of the reactor facility. The net effect of the outreach program is greater campus communication and awareness of the unique capabilities as applied to each discipline. A natural product of the outreach program should be increased research

  5. Devious Lies: Adventures in Freelance Science Outreach

    Fatland, D. R.

    2003-12-01

    Observations are given from two freelance science outreach projects undertaken by the author: Tutoring at-risk secondary students and teaching astronomy to 5th-7th graders in a camp retreat environment. Two recurring thematic challenges in these experiences are considered: First the 'Misperception Problem', the institutionalized chasm between the process of doing science and K-12 science education (wherein science is often portrayed as something distant and inaccessible, while ironically children are necessarily excellent scientists). And second the 'Engagement Problem', engaging a student's attention and energy by matching teaching material and--more importantly--teaching techniques to the student's state of development. The objective of this work is twofold: To learn how to address these two challenges and to empower the students in a manner independent of the scientific content of any particular subject. An underlying hypothesis is that confidence to problem solve (a desirable life-skill) can be made more accessible through a combination of problem solving by the student and seeing how others have solved seemingly impossible problems. This hypothesis (or agenda) compels an emphasis on critical thinking and raises the dilemma of reconciling non-directed teaching with very pointed conclusions about the verity of pseudo-science and ideas prevalent about science in popular culture. An interesting pedagogical found-object in this regard is the useful 'devious lie' which can encourage a student to question the assumption that the teacher (and by extension any professed expert) has the right answers.

    2017-10-01

    The 2017 total solar eclipse is an unprecedented opportunity for astronomical education throughout the continental United States. With the path of totality passing through 14 states, from Oregon to South Carolina, the United States is expecting visitors from all around the world. Due to the likelihood of clear skies, Idaho was a popular destination for eclipse-chasers. In spite of considerable enthusiasm and interest by the general population, the resources for STEM outreach in the rural Pacific Northwest are very limited. In order to help prepare Idaho for the eclipse, we put together a crowdfunding campaign through the university and raised over $10,000. Donors received eclipse shades as well as information about the eclipse specific to Idaho. Idaho expects 500,000 visitors, which could present a problem for the many small, rural towns scattered across the path of totality. In order to help prepare and equip the public for the solar eclipse, we conducted a series of site visits to towns in and near the path of totality throughout Idaho. To maximize the impact of this effort, the program included several partnerships with local educational and community organizations and a focus on the sizable refugee and low-income populations in Idaho, with considerable attendance at most events.

    Few astronomical objects excite students more than big explosions and black holes. Gamma Ray Bursts (GRBs) are both: powerful explosions that signal the births of black holes. NASA's Swift satellite mission, set for launch in Fall 2004, will detect hundreds of black holes over its two-year nominal mission timeline. The NASA Education and Public Outreach (E/PO) group at Sonoma State University is leading the Swift E/PO effort, using the Swift mission to engage students in science and math learning. We have partnered with the Lawrence Hall of Science to create a ``Great Explorations in Math and Science" guide entitled ``Invisible Universe: from Radio Waves to Gamma Rays," which uses GRBs to introduce students to the electromagnetic spectrum and the scale of energies in the Universe. We have also created new standards-based activities for grades 9-12 using GRBs: one activity puts the students in the place of astronomers 20 years ago, trying to sort out various types of stellar explosions that create high-energy radiation. Another mimics the use of the Interplanetary Network to let students figure out the direction to a GRB. Post-launch materials will include magazine articles about Swift and GRBs, and live updates of GRB information to the Swift E/PO website that will excite and inspire students to learn more about space science.

    To provide Science, Technology, Engineering, and Math (STEM) outreach and education to secondary students to encourage them to select science and engineering as a career by providing an engineering-based problem-solving experience involving renewable energy systems such as photovoltaic (PV) panels or wind turbines. All public and private schools, community colleges, and vocational training programs would be eligible for participation. The Power Microgrids High School Engineering Experience used renewable energy systems (PV and wind) to provide a design capstone experience to secondary students. The objective for each student team was to design a microgrid for the student’s school using renewable energy sources under cost, schedule, performance, and risk constraints. The students then implemented their designs in a laboratory environment to evaluate the completeness of the proposed design, which is a unique experience even for undergraduate college students. This application-based program was marketed to secondary schools in the 28th Congressional District through the Texas Education Agency’s (TEA) Regional Service Centers. Upon application, TEES identified regionally available engineers to act as mentors and supervisors for the projects. Existing curriculum was modified to include microgrid and additional renewable technologies and was made available to the schools.

    Full Text Available Given the emphasis in Higher Education on community engagement in South Africa and the importance of international collaboration, we discuss a joint approach to chemistry outreach in two countries on two continents with widely differing target school audiences. We describe the history of the partnership between the chemistry departments at Rhodes University and the University of Bristol and provide an outline of the chemistry content of their outreach initiatives, the modes of delivery, the advantages to both departments and their students for involvement in various levels of outreach, the challenges they still face and additional opportunities that such work facilitated. The lecture demonstration ‘A Pollutant’s Tale’ was presented to thousands of learners all over the world, including learners at resource-deprived schools in South Africa. Challenges to extend outreach activities in South Africa include long travelling distances, as well as a lack of facilities (such as school halls and electricity at schools. Outreach activities not only impacted on the target audience of young learners, they also impacted upon the postgraduate and other chemistry students taking part in these initiatives. This collaboration strengthened both institutions and their outreach work and may also lead to chemistry research collaborations between the academics involved.

    Production of corn-based ethanol (either by wet milling or by dry milling) yields the following coproducts: distillers grains with solubles (DGS), corn gluten meal (CGM), corn gluten feed (CGF), and corn oil. Of these coproducts, all except corn oil can replace conventional animal feeds, such as corn, soybean meal, and urea. Displacement ratios of corn-ethanol coproducts including DGS, CGM, and CGF were last updated in 1998 at a workshop at Argonne National Laboratory on the basis of input from a group of experts on animal feeds, including Prof. Klopfenstein (University of Nebraska, Lincoln), Prof. Berger (University of Illinois, Urbana-Champaign), Mr. Madson (Rapheal Katzen International Associates, Inc.), and Prof. Trenkle (Iowa State University) (Wang 1999). Table 1 presents current dry milling coproduct displacement ratios being used in the GREET model. The current effort focuses on updating displacement ratios of dry milling corn-ethanol coproducts used in the animal feed industry. Because of the increased availability and use of these coproducts as animal feeds, more information is available on how these coproducts replace conventional animal feeds. To glean this information, it is also important to understand how industry selects feed. Because of the wide variety of available feeds, animal nutritionists use commercial software (such as Brill Formulation{trademark}) for feed formulation. The software recommends feed for the animal on the basis of the nutritional characteristics, availability, and price of various animal feeds, as well as on the nutritional requirements of the animal (Corn Refiners Association 2006). Therefore, feed formulation considers both the economic and the nutritional characteristics of feed products.

    Outreach echocardiographic services led by cardiac sonographers may help district level hospitals in the management of patients suspected to have cardiac anomalies. However, the safety and utility of such an approach is not tested. We retrospectively reviewed our experience of patients seen in the outreach visits by the echocardiographers alone and subsequently reviewed in the pediatric cardiology clinic. Comparison between the diagnosis made by the echocardiographer and the consultant pediatric cardiologist were done. We defined safety as no change in patient management plan between the outreach evaluation and the pediatric cardiology clinic evaluation, and we defined usefulness as being beneficial, serviceable and of practical use. Two senior echocardiographic technicians did 41 clinic visits and over a period of 17 months, 623 patients were seen. Patients less than 3 months of age constitute 63% of the total patients seen. Normal echocardiographic examinations were found in 342 (55%) of patients. These patients were not seen in our cardiology clinic. Abnormal echocardiographic examinations were found in 281 (45%) of patients. Among the 281 patients with abnormal echos in the outreach visits, 251 patients (89.3%) were seen in the pediatric cardiology clinic. Comparing the results of the outreach clinic evaluation to that of the pediatric cardiology clinic, 73 patients (29%) diagnosed to have a minor CHD turned to have normal echocardiographic examinations. In all patients seen in both the outreach clinics and the pediatric tertiary cardiac clinics there was no change in patient's management plan. Outreach clinic conducted by pediatric echo sonographers could be useful and safe. It may help in reducing unnecessary visits to pediatric cardiology clinics, provide parental reassurance, and help in narrowing the differential diagnosis in critically ill patient unable to be transferred to tertiary cardiac centers provided it is done by experienced echosonographers

    2011-12-01

    The Society of Physics Students (SPS) is a professional organization specifically designed for college students. A main purpose of SPS is to develop college students into effective members of the physics community; one of the best ways to do this is by promoting science outreach. College students are in a prime position to engage the public in outreach to increase scientific literacy: they're easier for younger, school-age students to identify with, they can reach young adults in a unique way, and they're old enough to seriously engage the general public. SPS helps hundreds of college chapters across the country engage in outreach. One such chapter is at Rhodes College in Memphis, TN. The Rhodes College SPS chapter is active both in K12 schools and on its campus. Rhodes developed a position within its SPS structure to include an officer specifically related to handling outreach. For K12 schools this involved contacting teachers, organizing lessons, and holding training sessions for the college students preparing to teach the lessons. Rhodes SPS also focuses on campus outreach and trying to disabuse students of the notion that physics is stuffy, boring, and only for geniuses. Every fall, Rhodes SPS hosts an extremely popular annual Pumpkin Drop, as well as hosting demo shows, observatory open houses, and contests throughout the year for its students. One of the best received campus outreach programs is something called 'Stall Stories,' where SPS publishes a page flyer that goes in bathrooms around campus involving fun physics, a comic, and a list of SPS events. Rhodes SPS, like the national organization, has the goal of improving physics literacy among K12 students, college students, and the general public through effective outreach.

  19. NASA Sounding Rocket Program Educational Outreach

    Rosanova, G.

    2013-01-01

    Educational and public outreach is a major focus area for the National Aeronautics and Space Administration (NASA). The NASA Sounding Rocket Program (NSRP) shares in the belief that NASA plays a unique and vital role in inspiring future generations to pursue careers in science, mathematics, and technology. To fulfill this vision, the NSRP engages in a variety of educator training workshops and student flight projects that provide unique and exciting hands-on rocketry and space flight experiences. Specifically, the Wallops Rocket Academy for Teachers and Students (WRATS) is a one-week tutorial laboratory experience for high school teachers to learn the basics of rocketry, as well as build an instrumented model rocket for launch and data processing. The teachers are thus armed with the knowledge and experience to subsequently inspire the students at their home institution. Additionally, the NSRP has partnered with the Colorado Space Grant Consortium (COSGC) to provide a "pipeline" of space flight opportunities to university students and professors. Participants begin by enrolling in the RockOn! Workshop, which guides fledgling rocketeers through the construction and functional testing of an instrumentation kit. This is then integrated into a sealed canister and flown on a sounding rocket payload, which is recovered for the students to retrieve and process their data post flight. The next step in the "pipeline" involves unique, user-defined RockSat-C experiments in a sealed canister that allow participants more independence in developing, constructing, and testing spaceflight hardware. These experiments are flown and recovered on the same payload as the RockOn! Workshop kits. Ultimately, the "pipeline" culminates in the development of an advanced, user-defined RockSat-X experiment that is flown on a payload which provides full exposure to the space environment (not in a sealed canister), and includes telemetry and attitude control capability.

    Cox, N. L. J.

    2002-01-01

    The poster presented will give an overview of a study towards a "Space Road Show". The topic of this show is space science. The target group is adolescents, aged 12 to 15, at Dutch high schools. The show and its accompanying experiments would be supported with suitable educational material. Science teachers at schools can decide for themselves if they want to use this material in advance, afterwards or not at all. The aims of this outreach effort are: to motivate students for space science and engineering, to help them understand the importance of (space) research, to give them a positive feeling about the possibilities offered by space and in the process give them useful knowledge on space basics. The show revolves around three main themes: applications, science and society. First the students will get some historical background on the importance of space/astronomy to civilization. Secondly they will learn more about novel uses of space. On the one hand they will learn of "Views on Earth" involving technologies like Remote Sensing (or Spying), Communication, Broadcasting, GPS and Telemedicine. On the other hand they will experience "Views on Space" illustrated by past, present and future space research missions, like the space exploration missions (Cassini/Huygens, Mars Express and Rosetta) and the astronomy missions (Soho and XMM). Meanwhile, the students will learn more about the technology of launchers and satellites needed to accomplish these space missions. Throughout the show and especially towards the end attention will be paid to the third theme "Why go to space"? Other reasons for people to get into space will be explored. An important question in this is the commercial (manned) exploration of space. Thus, the questions of benefit of space to society are integrated in the entire show. It raises some fundamental questions about the effects of space travel on our environment, poverty and other moral issues. The show attempts to connect scientific with

    2003-01-01

    The Student Outreach with Renewable Energy Technology (SORET) program is a joint grant that involves a collaboration between three HBCU's (Central State University, Savannah State University, and Wilberforce University) and NASA John H. Glenn Research Center at Lewis Field. The overall goal of the grant is to increase the interest of minority students in the technical disciplines, to encourage participating minority students to continue their undergraduate study in these disciplines, and to promote graduate school to these students. As a part of SORET, Central State University has developed an undergraduate research associates program over the past two years. As part of this program, students are required to take special laboratory courses offered at Wilberforce University that involve the application of renewable energy systems. The course requires the students to design, construct, and install a renewable energy project. In addition to the applied renewable energy course, Central State University provided four undergraduate research associates the opportunity to participate in summer internships at Texas Southern University (Renewable Energy Environmental Protection Program) and the Cleveland African-American Museum (Renewable Energy Summer Camp for High School Students) an activity co sponsored by NASA and the Cleveland African-American Museum. Savannah State University held a high school summer program with a theme of the Direct Impact of Science on Our Every Day Lives. The purpose of the institute was to whet the interest of students in science, mathematics, engineering, and technology (SMET) by demonstrating the effectiveness of science to address real world problems. The 2001 institute involved the design and installation of a PV water pumping system at the Center for Advanced Water Technology and Energy Systems at Savannah State. Both high school students and undergraduates contributed to this project. Wilberforce University has used NASA support to provide

  2. Bioenergy from stillage anaerobic digestion to enhance the energy balance ratio of ethanol production.

    Fuess, Lucas Tadeu; Garcia, Marcelo Loureiro

    2015-10-01

    The challenges associated with the availability of fossil fuels in the past decades intensified the search for alternative energy sources, based on an ever-increasing demand for energy. In this context, the application of anaerobic digestion (AD) as a core treatment technology in industrial plants should be highlighted, since this process combines the pollution control of wastewaters and the generation of bioenergy, based on the conversion of the organic fraction to biogas, a methane-rich gaseous mixture that may supply the energetic demands in industrial plants. In this context, this work aimed at assessing the energetic potential of AD applied to the treatment of stillage, the main wastewater from ethanol production, in an attempt to highlight the improvements in the energy balance ratio of ethanol by inserting the heating value of methane as a bioenergy source. At least 5-15% of the global energy consumption in the ethanol industry could be supplied by the energetic potential of stillage, regardless the feedstock (i.e. sugarcane, corn or cassava). The association between bagasse combustion and stillage anaerobic digestion in sugarcane-based distilleries could provide a bioenergy surplus of at least 130% of the total fossil fuel input into the ethanol plant, considering only the energy from methane. In terms of financial aspects, the economic gains could reach US$ 0.1901 and US$ 0.0512 per liter of produced ethanol, respectively for molasses- (Brazil) and corn-based (EUA) production chains. For large-scale (∼1000 m(3)EtOH per day) Brazilian molasses-based plants, an annual economic gain of up to US$ 70 million could be observed. Considering the association between anaerobic and aerobic digestion, for the scenarios analyzed, at least 25% of the energetic potential of stillage would be required to supply the energy consumption with aeration, however, more suitable effluents for agricultural application could be produced. The main conclusion from this work

    Many Saskatchewan communities are interested in the potential benefits of establishing an ethanol production facility. A guide is presented to outline areas that communities should consider when contemplating the development of an ethanol production facility. Political issues affecting the ethanol industry are discussed including environmental impacts, United States legislation, Canadian legislation, and government incentives. Key success factors in starting a business, project management, marketing, financing, production, physical requirements, and licensing and regulation are considered. Factors which must be taken into consideration by the project manager and team include markets for ethanol and co-products, competent business management staff, equity partners for financing, production and co-product utilization technologies, integration with another facility such as a feedlot or gluten plant, use of outside consultants, and feedstock, water, energy, labour, environmental and site size requirements. 2 figs., 2 tabs

    2013-03-01

    We have established a mobile nanoscience laboratory outreach program in Western NC that puts scanning electron microscopy (SEM) directly in the hands of K-12 students and the general public. There has been a recent push to develop new active learning materials to educate students at all levels about nanoscience and nanotechnology. Previous projects, such as Bugscope, nanoManipulator, or SPM Live! allowed remote access to advanced microscopies. However, placing SEM directly in schools has not often been possible because the cost and steep learning curve of these technologies were prohibitive, making this project quite novel. We have developed new learning modules for a microscopy outreach experience with a tabletop SEM (Hitachi TM3000). We present here an overview of our outreach and results of the assessment of our program to date.

    The production of ethanol from food such as corn, cassava etc. is the most predominate way of producing ethanol. This has led to a shortage in food, inbalance in food chain, increased food price and indirect land use. This thesis thus explores using another feed for the production of ethanol- hence ethanol from cellulose. Sawdust was used to carry out the experiment from the production of ethanol and two methods were considered: SHF (Separate Hydrolysis and Fermentation) and SSF (Simultaneous...

    2001-01-01

    In this report are presented results achieved on the process optimisation of bioethanol production from wheat straw, carried out within the ENEA's project of biomass exploitation for renewable energy. The process consists of three main steps: 1) biomass pretreatment by means of steam explosion; 2) enzymatic hydrolysis of the cellulose fraction; 3) fermentation of glucose. To perform the hydrolysis step, two commercial enzymatic mixtures have been employed, mainly composed by β-glucosidase (cellobiase), endo-glucanase and exo-glucanase. The ethanologenic yeast Saccharomyces cerevisiae has been used to ferment the glucose in he hydrolyzates. Hydrolysis yield of 97% has been obtained with steam exploded wheat straw treated at 220 0 C for 3 minutes and an enzyme to substrate ratio of 4%. It has been pointed out the necessity of washing with water the pretreated what straw, in order to remove the biomass degradation products, which have shown an inhibition effect on the yeast. At the best process conditions, a fermentation yield of 95% has been achieved. In the Simultaneous Saccharification and Fermentation process, a global conversion of 92% has been obtained, which corresponds to the production of about 170 grams of ethanol per kilogram of exploded straw [it

  12. From Ethanol to Salsolinol: Role of Ethanol Metabolites in the Effects of Ethanol

    Directory of Open Access Journals (Sweden)

    Alessandra T. Peana

    2016-01-01

    Full Text Available In spite of the global reputation of ethanol as the psychopharmacologically active ingredient of alcoholic drinks, the neurobiological basis of the central effects of ethanol still presents some dark sides due to a number of unanswered questions related to both its precise mechanism of action and its metabolism. Accordingly, ethanol represents the interesting example of a compound whose actions cannot be explained as simply due to the involvement of a single receptor/neurotransmitter, a scenario further complicated by the robust evidence that two main metabolites, acetaldehyde and salsolinol, exert many effects similar to those of their parent compound. The present review recapitulates, in a perspective manner, the major and most recent advances that in the last decades boosted a significant growth in the understanding on the role of ethanol metabolism, in particular, in the neurobiological basis of its central effects.

  13. Social opportunity and ethanol drinking in rats.

    2004-11-01

    Two experiments were designed to evaluate the effects of pairings of ethanol sipper conditioned stimulus (CS) with social opportunity unconditioned stimulus (US) on ethanol sipper CS-directed drinking in rats. In both experiments, rats were deprived of neither food nor water, and initiation of drinking of unsweetened 3% ethanol was evaluated, as were the effects of increasing the concentration of unsweetened ethanol (3-10%) across sessions. In Experiment 1, Group Paired (n=8) received 35 trials per session wherein the ethanol sipper CS was presented for 10 s immediately prior to 15 s of social opportunity US. All rats initiated sipper CS-directed drinking of 3% ethanol. Increasing the concentration of ethanol in the sipper CS [(3%, 4%, 6%, 8%, 10% (vol./vol.)] across sessions induced escalation of daily g/kg ethanol intake. To evaluate the hypothesis that the drinking in Group Paired was due to autoshaping, Experiment 2 included a pseudoconditioning control that received sipper CS and social opportunity US randomly with respect to one another. All rats in Group Paired (n=6) and in Group Random (n=6) initiated sipper CS-directed drinking of 3% ethanol and daily mean g/kg ethanol intake in the two groups was comparable. Also comparable was daily g/kg ethanol intake, which increased for both groups with the availability of higher concentrations of ethanol in the sipper CS, up to a maximum of approximately 0.8 g/kg ethanol intake of 10% ethanol. Results indicate that random presentations of ethanol sipper CS and social opportunity US induced reliable initiation and escalation of ethanol intake, and close temporally contiguous presentations of CS and US did not induce still additional ethanol intake. This may indicate that autoshaping CR performance is not induced by these procedures, or that high levels of ethanol intake induced by factors related to pseudoconditioning produces a ceiling effect. Implications for ethanol drinking in humans are discussed.

  2. [An ethical reflection on outreaching mental health care].

    Science.gov (United States)

    Liégeois, A; Eneman, M

    Care providers have a conflicting societal role: on the one hand they must respect the autonomy of individuals with psychiatric problems, but on the other hand they often feel the need to offer these individuals outreaching care. To compile an ethical reflection on some of the ways in which outreaching mental health care interventions can be provided in a responsible manner. This ethical reflection is based on an ethical advice by the Ethics committee for Mental Health Care of the Brothers of Charity in Flanders. The method combines ethical discussion and a study of the relevant literature. A good starting point is a relational view of the human being that emphasises connectedness and involvement. Consequently, the care provider begins to intervene in the care programme by building a trusting relationship with the person with psychiatric problems. This is how these persons, their close family and friends and care providers exercise their responsibility. There is a gradation of responsibility that extends in a continuous line: personal responsibility develops into shared responsibility which can then become vicarious responsibility. On that basis there is also a gradation in the nature of outreaching care; the care providers first make themselves available and give information, then provide advice, negotiate, persuade, increase pressure, and finally take over and force the person with psychiatric problems. The care providers choose in dialogue and in a considered and consistent way for the appropriate form of outreaching care, in line with the degree of responsibility that the person with psychiatric problems can assume.

    Annet Pauwelussen

    2017-05-01

    Full Text Available Drawing on long-term ethnographic research in Indonesia, this article describes a conservation outreach project that attempts to educate and convert local people into coral protectors. Both coral and the sea-dwelling Bajau people appear to be amphibious beings, moving between a changeable land-water interface, and between different, fluidly interwoven ontological constellations. We show that the failure of conservation organizations to recognize the ontologically ambiguous nature of “coral” and “people” translates to a breakdown of outreach goals. Mobilizing the concept of amphibiousness to engage this ambiguity and fluidity, we describe the moving land-water interface as the actual living environment for both coral and people. The notion of amphibiousness, we suggest, has practical and political value, in particular for reconsidering outreach and how it may be reframed as a process involving ontological dialogue. For conservation outreach to become seaworthy, it needs to cultivate an amphibious capacity, capable of moving in-between and relating partly overflowing ways of knowing and being. Providing room for ambiguity, thinking with amphibiousness furthermore encourages suspension of the (Western tendency to explain the Other, to fix what does not add up. As such, it is of heuristic relevance for the on-going discussions of ontological multiplicity that have proliferated at the intersection between STS and anthropology.

    2006-12-01

    The International Heliophysical Year (IHY) will celebrate the 50th anniversary of the International Geophysical Year (IGY) and will continue its tradition of international research collaboration. The term "heliophysical" is an extension of the term "geophysical", where the Earth, Sun & Solar System are studied not as separate domains but through the universal processes governing the heliosphere. IHY represents a logical next-step, extending the studies into the heliosphere and thus including the drivers of geophysical change. The main goal of IHY Education and Outreach Program is to create more global access to exemplary resources in space and earth science education and public outreach. By taking advantage of the IHY organization with representatives in every nation and in the partnership with the United Nations Basic Space Science Initiative (UNBSSI), we aim to promote new international partnerships. Our goal is to assist in increasing the visibility and accessibility of exemplary programs and in the identification of formal or informal educational products that would be beneficial to improve the space and earth science knowledge in a given country; leaving a legacy of enhanced global access to resources and of world-wide connectivity between those engaged in education and public outreach efforts that are related to IHY science. Here we describe the IHY Education and Outreach Program, how to participate and the benefits in doing so. ~

  17. Monitoring and evaluating astronomy outreach programmes: Challenges and solutions

    Directory of Open Access Journals (Sweden)

    Sarah Chapman

    2015-05-01

    Full Text Available A number of tools exist to guide the monitoring and evaluation of science, technology, engineering and mathematics (STEM education and outreach programmes. Fewer tools exist for evaluating astronomy outreach programmes. In this paper we try to overcome this limitation by presenting a monitoring and evaluation framework developed for the International Astronomical Union's Office of Astronomy for Development (OAD. The mandate of the OAD is to stimulate sustainable development at an international level and to expand astronomy education and outreach globally. The broad assumptions of this programme are that astronomy has the potential to contribute to human development by means of the transferable nature of its science discoveries, as well as its potential to activate feelings of wonderment, inspiration and awareness of the universe. As a result, the programme potentially embodies a far broader mix of outcomes than conventionally considered in STEM evaluation approaches. Towards this aim, we operationalise our monitoring and evaluation approach by first outlining programme theories for three key OAD programmes: a programme for universities and research, another one for schools, and one for public outreach. We then identify outcomes, indicators and measures for each one of these programmes. We conclude with suggestions for evaluating the global impact of astronomy for development.

  20. The science of science outreach: methods to maximise audience engagement

    Science.gov (United States)

    Adamson, Kathryn; Lane, Timothy

    2016-04-01

    Effective public engagement relies on a clear understanding of public audiences; their existing knowledge base and their learning preferences. Scientific content that is effective in academic spheres is not necessarily popular in the public domain. This may be due to content (e.g. beginner level to advanced terminology); presentation style (graphical, text, multimedia); audience demographic (children to adults); and entertainment value. Over the last few years, there has been a major expansion in the quantity and quality of science outreach material. For scientists, the production of outreach material, in any form, is the first giant leap to disseminating their knowledge to broader audiences. However, there is also a need to evaluate the performance of outreach material, so that its content and delivery style can be tailored and maximised for the target audience. We examine the Google Analytics data for climate science outreach website Climatica over a 12 month period in 2015. The site publishes regular posts, which take the form of short written articles, graphics, videos, or teaching resources, on all aspects of climate science. The site is publicised via social media including Twitter and Facebook. In particular, we assess website performance, in terms of website visits and post engagement. These are examined in the context of: post topic, post style, social media engagement, and the timing of post publication/advertisement. The findings of this investigation are used to explore audience preferences and mechanisms for future post development to maximise the use of this web resource.

  4. Ethanol Demand in United States Gasoline Production

    Energy Technology Data Exchange (ETDEWEB)

    Hadder, G.R.

    1998-11-24

    The Oak Ridge National Laboratory (OWL) Refinery Yield Model (RYM) has been used to estimate the demand for ethanol in U.S. gasoline production in year 2010. Study cases examine ethanol demand with variations in world oil price, cost of competing oxygenate, ethanol value, and gasoline specifications. For combined-regions outside California summer ethanol demand is dominated by conventional gasoline (CG) because the premised share of reformulated gasoline (RFG) production is relatively low and because CG offers greater flexibility for blending high vapor pressure components like ethanol. Vapor pressure advantages disappear for winter CG, but total ethanol used in winter RFG remains low because of the low RFG production share. In California, relatively less ethanol is used in CG because the RFG production share is very high. During the winter in California, there is a significant increase in use of ethanol in RFG, as ethanol displaces lower-vapor-pressure ethers. Estimated U.S. ethanol demand is a function of the refiner value of ethanol. For example, ethanol demand for reference conditions in year 2010 is 2 billion gallons per year (BGY) at a refiner value of $1.00 per gallon (1996 dollars), and 9 BGY at a refiner value of $0.60 per gallon. Ethanol demand could be increased with higher oil prices, or by changes in gasoline specifications for oxygen content, sulfur content, emissions of volatile organic compounds (VOCS), and octane numbers.

    NASA is working with four newly-formed Science Education and Public Outreach Forums (SEPOFs) to increase the overall coherence of the Science Mission Directorate (SMD) Education and Public Outreach (E/PO) program. SEPOFs support the astrophysics, heliophysics, planetary and Earth science divisions of NASA SMD in three core areas: * E/PO Community Engagement and Development * E/PO Product and Project Activity Analysis * Science Education and Public Outreach Forum Coordination Committee Service. SEPOFs are collaborating with NASA and external science and education and outreach communities in E/PO on multiple levels ranging from the mission and non-mission E/PO project activity managers, project activity partners, and scientists and researchers, to front line agents such as naturalists/interpreters, teachers, and higher education faculty, to high level agents such as leadership at state education offices, local schools, higher education institutions, and professional societies. The overall goal for the SEPOFs is increased awareness, knowledge, and understanding of scientists, researchers, engineers, technologists, educators, product developers, and dissemination agents of best practices, existing NASA resources, and community expertise applicable to E/PO. By coordinating and supporting the NASA E/PO Community, the NASA/SEPOF partnerships will lead to more effective, sustainable, and efficient utilization of NASA science discoveries and learning experiences.

  6. Fermentation of hexoses to ethanol

    2000-06-01

    The Goals of the project has been: to increase the ethanol yield by reducing the by-product formation, primarily biomass and glycerol, and to prevent stuck fermentations, i.e. to maintain a high ethanol production rate simultaneously with a high ethanol yield. The studies have been performed both in defined laboratory media and in a mixture of wood- and wheat hydrolysates. The yeast strains used have been both industrial strains of bakers yeast, Saccharomyces cerevisiae, and haploid laboratory strains. The Relevance of these studies with respect to production of ethanol to be used as fuel is explained by: With the traditional process design used today, it is very difficult to reach a yield of more than 90 % of the theoretical maximal value of ethanol based on fermented hexose. During 'normal' growth and fermentation conditions in either anaerobic batch or chemostat cultures, substrate is lost as biomass and glycerol in the range of 8 to 11 % and 6 to 11 % of the substrate consumed (kg/kg). It is essential to reduce these by-products. Traditional processes are mostly batch processes, in which there is a risk that the biocatalyst, i.e. the yeast, may become inactivated. If for example yeast biomass production is avoided by use of non-growing systems, the ethanol production rate is instantaneously reduced by at least 50%. Unfortunately, even if yeast biomass production is not avoided on purpose, it is well known that stuck fermentations caused by cell death is a problem in large scale yeast processes. The main reason for stuck fermentations is nutrient imbalances. For a good process economy, it is necessary to ensure process accessibility, i.e. to maintain a high and reproducible production rate. This will both considerably reduce the necessary total volume of the fermentors (and thereby the investment costs), and moreover minimize undesirable product fall-out.

    Corn, wheat, sugar cane.. The multiplication of biofuel refineries has led to a rise of the prices of agriculture products. The question is: do we need ethanol? The US situation gives an answer: the offer exceeds the demand and ethanol prices have dropped down. Other environmental and socio-economical consequences of biofuels development are put forward by the UNO, the IMF and by non-governmental organizations who foresee a dramatic rise of food products prices and an aggravation of starvation in developing countries.

Interested companies have been asked to quote for capacities of 60,000, 120,000 and 180,000 litre per day. The initial tender calls for three plants but the figure could rise to ten which would then be worth about $20 million.

    zA theoretical evaluation of heat-integrated heterogeneous-azeotropic ethanol-water distillation flowsheets is presented. Simulations of two column flowsheets using several different hydrocarbon entrainers reveal a region of potential heat integration and substantial reduction in operating energy. In this paper, methods for comparing hydrocarbon entrainers are shown. Two aspects of entrainers are related to operating and capital costs. The binary azeotropic composition of the entrainer-ethanol mixture is related to the energy requirements of the flowsheet. A temperature difference in the azeotrophic column is related to the size of the column and overall process staging requirements. Although the hydrophobicity of an entrainer is essential for specification of staging in the dehydration column, no substantial increase in operating energy results from an entrainer that has a higher water content. Likewise, liquid-liquid equilibria between several entrainer-ethanol-water mixtures have no substantial effect on either staging or operation. Rather, increasing the alcohol content of the entrainer-ethanol azeotrope limits its recovery in the dehydration column, and increases the recycle and reflux streams. These effects both contribute to increasing the separation energy requirements and reducing the region of potential heat integration. A cost comparison with a multieffect extractive distillation flowsheet reveals that the costs are comparable; however, the extractive distillation flowsheet is more cost effective as operating costs increase.

  13. The ontogeny of ethanol aversion.

    Saalfield, Jessica; Spear, Linda

    2016-03-15

    Recent work has suggested separate developmental periods within the broader framework of adolescence, with data suggesting distinct alterations and vulnerabilities within these intervals. While previous research has suggested reduced sensitivity to the aversive effects of alcohol in adolescence relative to adults, a more detailed ontogeny of this effect has yet to be conducted. The adolescent brain undergoes significant transitions throughout adolescence, including in regions linked with drug reward and aversion. The current study aimed to determine the ontogeny of ethanol aversion by utilizing a conditioned taste aversion procedure at six different ages to test the hypothesis that the transitions into, through, and out of adolescence are associated with ontogenetic alterations in sensitivity to the aversive properties of ethanol. Non-deprived animals given Boost® as the conditioned stimulus (CS) were used in Experiment 1, whereas Experiment 2 used water-restricted animals provided with a saccharin/sucrose solution as the CS. In both experiments, an attenuated sensitivity to the aversive properties of ethanol was evident in adolescents compared to adults, although more age differences were apparent in water deprived animals than when a highly palatable CS was given to ad libitum animals. Overall, the data suggest an attenuated sensitivity to the aversive properties of ethanol that is most pronounced during pre- and early adolescence, declining thereafter to reach the enhanced aversive sensitivity of adults.

    The U.S. Department of Energy (DOE) is very concerned about the lack of understanding of basic science. Increasingly, critical decisions regarding the use of energy, technology, and the environment are being made. A well-educated and science-literate public is vital to the success of these decisions. Science education and school instruction are integral parts of the DOE's public outreach program on the Yucca Mountain Site Characterization Project (YMP). Project staff and scientists speak to elementary, junior high, high school, and university students, accepting all speaking invitations. The objectives of this outreach program include the following: (1) educating Nevada students about the concept of a high-level nuclear waste repository; (2) increasing awareness of energy and environmental issues; (3) helping students understand basic concepts of earth science and geology in relation to siting a potential repository; and (4) giving students information about careers in science and engineering

    Full Text Available Both scientists and the public would benefit from improved communication of basic scientific research and from integrating scientists into education outreach, but opportunities to support these efforts are limited. We have developed two low-cost programs--"Present Your PhD Thesis to a 12-Year-Old" and "Shadow a Scientist"--that combine training in science communication with outreach to area middle schools. We assessed the outcomes of these programs and found a 2-fold benefit: scientists improve their communication skills by explaining basic science research to a general audience, and students' enthusiasm for science and their scientific knowledge are increased. Here we present details about both programs, along with our assessment of them, and discuss the feasibility of exporting these programs to other universities.

    The growing technology sector of the U.S. economy in an increasingly complex world has made it more important than ever for students to gather information, think critically, and solve problems. These skills are often acquired through the study of STEM disciplines. In an effort to inspire students and the public in the Charlotte, NC area to take an interest in STEM related fields, the Physics Department at Davidson College has recently developed an interactive astronomy community engagement program. This program is comprised of off-campus events that bring STEM programming to K-12 children, on-campus public star parties, and a day-long astronomy fair called Davidson Space Day. This presentation will illustrate the implementation of each of these components of our outreach program, present an evaluation of their success, and describe future goals and lessons learned thus far. This outreach program was made possible through funding from the NC Space Grant Consortium.

    in the framework of scientific outreach at the 'Maison des Sciences' of the Aix-Marseilles University, we created a teaching kit for holography contained in a small case. It includes all the required equipment to produce holograms almost anywhere with a simple optical assembly with a very good vibration tolerance. The fundamental principles of holography and several applications are illustrated through simple experiments: reflection Denisyuk holograms, angular multiplexing, notch filters, holographic interferometry and diffraction holographic gratings. It is possible to use this tool for several purposes: science outreach, teaching for undergraduate and graduate students and continuing education. In this article, we explain the basis of holography, how the kit works, and give some applications and results that can be done with it.

    Advances in the science of genetics have implications for individuals and society, and have to be taken into account at the policy level. Studies of ethical, legal and social issues related to genomic research have therefore been integrated in the Human Genome Project (HGP) since the earliest days of the project. Since 1990, three to five percent of the HGP annual budget has been devoted to such studies, under the umbrella of the Ethical, Legal, and Social Implications (ELSI) Programs of the National Human Genome Research Institute of the National Institute of Health, and of the Office of Biological and Environmental Research of the U.S. Department of Energy (DOE). The DOE-ELSI budget has been used to fund a variety of projects that have aimed at ?promoting education and help guide the conduct of genetic research and the development of related medical and public policies? (HGP, 2003). As part of the educational component, a significant portion of DOE-ELSI funds have been dedicated to public outreach projects, with the underlying goal of promoting public awareness and ultimately public discussion of ethical, legal, and social issues surrounding availability of genetic information (Drell, 2002). The essential assumption behind these projects is that greater access to information will lead to more knowledge about ethical, legal and social issues, which in turn will lead to enhanced ability on the part of individuals and communities to deal with these issues when they encounter them. Over the same period of time, new concepts of ?public understanding of science? have emerged in the theoretical realm, moving from a ?deficit? or linear dissemination of popularization, to models stressing lay-knowledge, public engagement and public participation in science policy-making (Lewenstein, 2003). The present project uses the base of DOE-funded ELSI educational project to explore the ways that information about a new and emerging area of science that is intertwined with public

    Low- and middle-income countries carry a disproportionate share of the global burden of pediatric surgical disease and have limited local healthcare infrastructure and human resources to address this burden. Humanitarian efforts that have improved or provided access to necessary basic or emergency surgery for children in these settings have included humanitarian assistance and disaster relief, short-term surgical missions, and long-term projects such as building pediatric specialty hospitals and provider networks. Each of these efforts may also include educational initiatives designed to increase local capacity. This article will provide an overview of pediatric humanitarian surgical outreach including reference to available evidence-based analyses of these platforms and make recommendations for surgical outreach initiatives for children.

    2008-12-01

    The Association of Polar Early Career Scientists (APECS) grew out of the 4th International Polar Year (IPY-4) 2007-08 and is an international and interdisciplinary organization of over 1200 undergraduate and graduate students, postdoctoral researchers, early faculty members, educators and others with interests in Polar Regions and the wider cryosphere from more than 40 countries. Our aims are to stimulate interdisciplinary and international research collaborations, and develop effective future leaders in polar research, education and outreach. As potentially one of the major legacies of IPY-4, APECS members have been at the forefront of increasing scientific knowledge and public interest in the polar regions, centered around global climate change, and enhancing scientific understanding, media attention, primary and secondary school (K-12) educational programs, undergraduate institutions, and public literacy campaigns. Research and Educational Outreach activities by APECS members during IPY-4 have improved both our understanding and the communication of all aspects of the Polar Regions and the importance of their broader global connections. APECS National Committees have run Polar Contests where young researchers partnered with teachers and students to develop curriculum and activities to share their research, have participated in many field based communication exchanges and are mentoring youth to pursue careers in science, and enhancing the public perception of scientists through photo, video and museum exhibits. In cooperation with the IPY Teachers Network and the IPY IPO, APECS is developing a polar education resource book that will feature education and outreach activities by young researchers, as well as provide examples of classroom activities for teachers to incorporate polar literacy into their curriculum and a How-To guide for researchers interested in conducting education and outreach.

    Facilities provide infrastructure for science that would not be feasible at a single institution. Facilities are also a resource for development of outreach products and activities that reach a national audience of diverse stakeholders. UNAVCO manages the NSF geodetic facility GAGE (Geodesy Advancing Geosciences and Earthscope). Staff at UNAVCO with expertise in education, outreach, and communication translate the science and supporting infrastructure into materials consumable by a wide array of users including teachers, students, museum attendees, emergency managers, park interpreters, and members of the general public. UNAVCO has the ability to distribute materials to a national and international audience, thereby greatly increasing the impact of the science and increasing the value of the investment by the National Science Foundation. In 2014 and 2015, UNAVCO produced multiple print products focused on the Plate Boundary Observatory (PBO), the geodetic component of EarthScope. Products include a deck of playing cards featuring PBO GPS stations, a poster featuring GPS velocities of the Western United States, and another poster focused on GPS velocities in Alaska. We are distributing these products to a broad audience, including teachers, station permit holders, and community members. The Tectonics of the Western United States poster was distributed this year in the American Geosciences Institute Earth Science Week kit for teachers, reaching 16,000 educators around the country. These posters and the PBO playing cards (PBO-52) were distributed to more than 100 teachers through workshops led by UNAVCO, the EarthScope National Office, the Southern California Earthquake Center (SCEC), and more. Additionally, these cards serve as a way to engage landowners who host these scientific stations on their property. This presentation will address the strategies for creating nationally relevant materials and the tools used for dissemination of materials to a broad audience. We

    We discuss our efforts to bring astronomy to local schools and classrooms through the UCI Astronomy Outreach program. This is part of a faculty-led outreach program entitled Outreach in Astronomy & Astrophysics with the UCI Observatory, funded by an NSF FOCUS grant to the University of California, Irvine. We primarily schedule visits with K-12 teachers in the Compton, Newport/Mesa and Santa Ana Unified School Districts, but often see scout troops and classes from other nearby schools. Often these schools don’t have the funding needed to bring their students to us, so we take small, portable telescopes to the schools, for both day and night visits, to give the students a chance to not only see a telescope, but to use one as well. For the schools that can find transportation to bring their students to campus, we include a tour of our observatory dome housing a 24-inch telescope used for outreach events and undergraduate research. In addition, we give interactive lectures and demonstrations to involve the students and get them excited about careers in science and science in general. We find that we help stimulate discussions before and after our visits, which can often help start or end a unit of astronomy within the schools’ curricula. We show feedback from teachers we have visited including the strengths of the program and suggestions/improvements for the future.

  9. Tutorial Video Series: Using Stakeholder Outreach to Increase ...

    Science.gov (United States)

    The limited amount of toxicity data on thousands of chemicals found in consumer products has led to the development of research endeavors such as the U.S. EPA’s Toxicity Forecaster (ToxCast). ToxCast uses high-throughput screening technology to evaluate thousands of chemicals for potential toxicity. At the end of 2013, U.S. EPA released ToxCast chemical data on almost 2,000 chemicals through the interactive Chemical Safety for Sustainability (iCSS) Dashboard. The iCSS Dashboard provides public access to the high-throughput screening data that can be used to inform the evaluation of the safety of chemicals. U.S. EPA recognized early in the development of ToxCast that stakeholder outreach was needed in order to translate the complex scientific information featured in the iCSS Dashboard and data, with the goal of educating the diverse user community through targeted efforts to increase data usage and analysis. Through survey feedback and the request of stakeholders, a series of tutorial videos to demonstrate how to access and use the data has been planned, and the first video of the series has been released to guide data usage. This presentation will describe the video tutorial strategy including an overview of: 1) Stakeholder outreach goals and approach; 2) Planning, production, and dissemination of tutorial videos; 3) Overview of Survey Feedback; 4) Overview of tutorial video usage statistics and usage of the ToxCast data.

    The increased popularity of mobile phone apps provide scientists with a new avenue for sharing and distributing data and knowledge with colleagues, while also providing meaningful education and outreach products for consumption by the general public. Our initial development of iPhone and Android apps centered on the distribution of exciting auroral images taken at the South Pole for education and outreach purposes. These portable platforms, with limited resources when compared to computers, presented a unique set of design and implementation challenges that we will discuss in this presentation. For example, the design must account for limited memory; screen size; processing power; battery life; and potentially high data transport costs. Some of these unique requirements created an environment that enabled undergraduate and high-school students to participate in the creation of these apps. Additionally, during development it became apparent that these apps could also serve as data analysis and engineering tools. Our presentation will further discuss our plans to use apps not only for Education and Public Outreach, but for teaching, science and engineering.

    A recent discussion debates the extent of human in-migration around protected areas (PAs) in the tropics. One proposed argument is that rural migrants move to bordering areas to access conservation outreach benefits. A counter proposal maintains that PAs have largely negative effects on local populations and that outreach initiatives even if successful present insufficient benefits to drive in-migration. Using data from Tanzania, we examined merits of statistical tests and spatial methods used previously to evaluate migration near PAs and applied hierarchical modeling with appropriate controls for demographic and geographic factors to advance the debate. Areas bordering national parks in Tanzania did not have elevated rates of in-migration. Low baseline population density and high vegetation productivity with low interannual variation rather than conservation outreach explained observed migration patterns. More generally we argue that to produce results of conservation policy significance, analyses must be conducted at appropriate scales, and we caution against use of demographic data without appropriate controls when drawing conclusions about migration dynamics. © 2014 Society for Conservation Biology.

    There is a fundamental need for the professional community to cultivate and nurture active relationships with amateur organizations. The rewards of such work are highly beneficial to general public education and town-gown relations, but are time-consuming and hard-won. New York City and the surrounding area is both ideally suited and unambiguously ill-suited for astronomy public outreach. I will detail the results of three major outreach efforts in coordination with the Amateur Astronomers Association of New York. I will highlight large public-space observing in the context of the Transit of Venus and star parties at other locations. I will also outline outreach efforts at William Paterson University, where two public nights and a Curiosity EDL event created a clear impact in Northern New Jersey. I will detail methods for encouraging and bringing out amateur observers to events, urban crowd management, publicity issues, and the benefits and pitfalls of social media in the promotion and execution of large-scale and moderate events.

    The ability of scientists to articulate the importance and value of their research has become increasingly important in the present climate of declining budgets, and this is most critical in the field of nuclear science ,where researchers must fight an uphill battle against negative public perception. Yet nuclear science encompasses important technical and societal issues that should be of primary interest to informed citizens, and the need for scientists trained in nuclear techniques are important for many applications in nuclear medicine, national security and future energy sources. The NSAC Education Subcommittee Report [1] identified the need for a nationally coordinated effort in nuclear science outreach, naming as its first recommendation that `the highest priority for new investment in education be the creation by the DOE and NSF of a Center for Nuclear Science Outreach'. This talk will review the present status of public outreach in nuclear science and highlight some specific efforts that have taken place during the World Year of Physics.

    The Pregnancy and Village Outreach Tibet (PAVOT) program, a model for community- and home-based maternal-newborn outreach in rural Tibet, is presented. This article describes PAVOT, including the history, structure, content, and activities of the program, as well as selected program outcome measures and demographic characteristics, health behaviors, and pregnancy outcomes of women who recently participated in the program. The PAVOT program was developed to provide health-related services to pregnant rural Tibetan women at risk of having an unattended home birth. The program involves training local healthcare workers and laypersons to outreach pregnant women and family members. Outreach includes basic maternal-newborn health education and simple obstetric and neonatal life-saving skills training. In addition, the program distributes safe and clean birth kits, newborn hats, blankets, and maternal micronutrient supplements (eg, prenatal vitamins and minerals). More than 980 pregnant women received outreach during the study period. More than 92% of outreach recipients reported receiving safe pregnancy and birth education, clean birthing and uterine massage skills instruction, and clean umbilical cord care training. Nearly 80% reported basic newborn resuscitation skills training. Finally, nearly 100% of outreach recipients received maternal micronutrient supplements and safe and clean birth kits. The PAVOT program is a model program that has been proven to successfully provide outreach to rural-living Tibetans by delivering maternal-newborn health education, skills training, and resources to the home.

    Prenatal ethanol significantly heightens later alcohol consumption, but the mechanisms that underlie this phenomenon are poorly understood. Little is known about the basis of this effect of prenatal ethanol on the sensitivity to ethanol’s reinforcing effects. One possibility is that prenatal ethanol exposure makes subjects more sensitive to the appetitive effects of ethanol or less sensitive to ethanol’s aversive consequences. The present study assessed ethanol-induced second-order conditioned place preference (CPP) and aversion and ethanol-induced conditioned taste aversion (CTA) in infant rats prenatally exposed to ethanol (2.0 g/kg) or vehicle (water) or left untreated. The involvement of the κ opioid receptor system in ethanol-induced CTA was also explored. When place conditioning occurred during the ascending limb of the blood-ethanol curve (Experiment 1), the pups exposed to ethanol in utero exhibited greater CPP than untreated controls, with a shift to the right of the dose-response curve. Conditioning during a later phase of intoxication (30–45 min post-administration; Experiment 2) resulted in place aversion in control pups exposed to vehicle during late gestation but not in pups that were exposed to ethanol in utero. Ethanol induced a reliable and similar CTA (Experiment 3) in the pups treated with vehicle or ethanol during gestation, and CTA was insensitive to κ antagonism. These results suggest that brief exposure to a moderate ethanol dose during late gestation promotes ethanol-mediated reinforcement and alters the expression of conditioned aversion by ethanol. This shift in the motivational reactivity to ethanol may be an underlying basis of the effect of prenatal ethanol on later ethanol acceptance. PMID:22698870

  17. Subsidies to target specialist outreach services into more remote locations: a national cross-sectional study.

    2017-07-01

    Objective Targeting rural outreach services to areas of highest relative need is challenging because of the higher costs it imposes on health workers to travel longer distances. This paper studied whether subsidies have the potential to support the provision of specialist outreach services into more remote locations. Methods National data about subsidies for medical specialist outreach providers as part of the Wave 7 Medicine in Australia: Balancing Employment and Life (MABEL) Survey in 2014. Results Nearly half received subsidies: 19% (n=110) from a formal policy, namely the Australian Government Rural Health Outreach Fund (RHOF), and 27% (n=154) from other sources. Subsidised specialists travelled for longer and visited more remote locations relative to the non-subsidised group. In addition, compared with non-subsidised specialists, RHOF-subsidised specialists worked in priority areas and provided equally regular services they intended to continue, despite visiting more remote locations. Conclusion This suggests the RHOF, although limited to one in five specialist outreach providers, is important to increase targeted and stable outreach services in areas of highest relative need. Other subsidies also play a role in facilitating remote service distribution, but may need to be more structured to promote regular, sustained outreach practice. What is known about this topic? There are no studies describing subsidies for specialist doctors to undertake rural outreach work and whether subsidies, including formal and structured subsidies via the Australian Government RHOF, support targeted outreach services compared with no financial support. What does this paper add? Using national data from Australia, we describe subsidisation among specialist outreach providers and show that specialists subsidised via the RHOF or another source are more likely to provide remote outreach services. What are the implications for practitioners? Subsidised specialist outreach providers are

  18. Renewable corn-ethanol and energy security

    International Nuclear Information System (INIS)

    Eaves, James

    2007-01-01

    Though corn-ethanol is promoted as renewable, models of the production process assume fossil fuel inputs. Moreover, ethanol is promoted as a means of increasing energy security, but there is little discussion of the dependability of its supply. This study investigates the sensibility of promoting corn-ethanol as an automobile fuel, assuming a fully renewable production process. We then use historical data to estimate the supply risk of ethanol relative to imported petroleum. We find that devoting 100% of US corn to ethanol would displace 3.5% of gasoline consumption and the annual supply of the ethanol would be inherently more risky than that of imported oil. Finally, because large temperature increases can simultaneously increase fuel demand and the cost of growing corn, the supply responses of ethanol producers to temperature-induced demand shocks would likely be weaker than those of gasoline producers.

    2014-12-01

    EarthScope's Education and Outreach (E&O) program aims to increase public awareness of Earth science and enhance geoscience education at the K-12 and college level. The program is distinctive among major geoscience programs in two ways. First, planning for education and public engagement occurred in tandem with planning for the science mission. Second, the NSF EarthScope program includes funding support for education and outreach. In this presentation, we highlight key examples of the program's accomplishments and identify emerging E&O opportunities. E&O efforts have been collaboratively led by the EarthScope National Office (ESNO), IRIS, UNAVCO, the EarthScope Education and Outreach Subcommittee (EEOSC) and PI-driven EarthScope projects. Efforts by the EEOSC, guided by an EarthScope Education and Outreach Implementation Plan that is periodically updated, focus EarthScope E&O. EarthScope demonstrated early success in engaging undergraduate students (and teachers) in its mission through their involvement in siting USArray across the contiguous U.S. Funded E&O programs such as TOTLE, Illinois EarthScope, CEETEP (for K-12), InTeGrate and GETSI (for undergraduates) foster use of freely available EarthScope data and research findings. The Next Generation Science Standards, which stress science and engineering practices, offer an opportunity for alignment with existing EarthScope K-12 educational resources, and the EEOSC recommends focusing efforts on this task. The EEOSC recognizes the rapidly growing use of mobile smart devices by the public and in formal classrooms, which bring new opportunities to connect with the public and students. This will capitalize on EarthScope's already prominent social media presence, an effort that developed to accomplish one of the primary goals of the EarthScope E&O Implementation Plan to "Create a high-profile public identity for EarthScope" and to "Promote science literacy and understanding of EarthScope among all audiences through

    2007-01-01

    The low ethanol tolerance of thermophilic anaerobic bacteria, generally less than 2% (v/v) ethanol, is one of the main limiting factors for their potential use for second generation fuel ethanol production. In this work, the tolerance of thermophilic anaerobic bacterium Thermoanaerobacter BG 1L1...... to exogenously added ethanol was studied in a continuous immobilized reactor system at a growth temperature of 70 degrees C. Ethanol tolerance was evaluated based on inhibition of fermentative performance e.g.. inhibition of substrate conversion. At the highest ethanol concentration tested (8.3% v/v), the strain...... was able to convert 42% of the xylose initially present, indicating that this ethanol concentration is not the upper limit tolerated by the strain. Long-term strain adaptation to high ethanol concentrations (6 - 8.3%) resulted in an improvement of xylose conversion by 25% at an ethanol concentration of 5...

  1. Delta receptor antagonism, ethanol taste reactivity, and ethanol consumption in outbred male rats.

    2006-11-01

    Naltrexone, a nonspecific opioid antagonist, produces significant changes in ethanol responsivity in rats by rendering the taste of ethanol aversive as well as producing a decrease in voluntary ethanol consumption. The present study investigated the effect of naltrindole, a specific antagonist of delta opioid receptors, on ethanol taste reactivity and ethanol consumption in outbred rats. In the first experiment, rats received acute treatment of naltrexone, naltrindole, or saline followed by the measurement of ethanol consumption in a short-term access period. The second experiment involved the same treatments and investigated ethanol palatability (using the taste-reactivity test) as well as ethanol consumption. Results indicated that treatment with 3 mg/kg naltrexone significantly affected palatability (rendered ethanol more aversive, Experiment 2) and decreased voluntary ethanol consumption (Experiments 1 and 2). The effects of naltrindole were inconsistent. In Experiment 1, 8 mg/kg naltrindole significantly decreased voluntary ethanol consumption but this was not replicated in Experiment 2. The 8 mg/kg dose produced a significant increase in aversive responding (Experiment 2) but did not affect ingestive responding. Lower doses of naltrindole (2 and 4 mg/kg) were ineffective in altering rats' taste-reactivity response to and consumption of ethanol. While these data suggest that delta receptors are involved in rats' taste-reactivity response to ethanol and rats' ethanol consumption, it is likely that multiple opioid receptors mediate both behavioral responses.

    Making effective and efficient use of outreach resources can be difficult for student groups in smaller rural communities. Washington State University's OSA/SPIE student chapter desires well attended yet cost-effective ways to educate and inform the public. We designed outreach activities focused on three different funding levels: low upfront cost, moderate continuing costs, and high upfront cost with low continuing costs. By featuring our activities at well attended events, such as a pre-football game event, or by advertising a headlining activity, such as a laser maze, we take advantage of large crowds to create a relaxed learning atmosphere. Moreover, participants enjoy casual learning while waiting for a main event. Choosing a particular funding level and associating with well-attended events makes outreach easier. While there are still many challenges to outreach, such as motivating volunteers or designing outreach programs, we hope overcoming two large obstacles will lead to future outreach success.

    Ethanol was administered to rats by means of a liquid diet for 16 days; after an ethanol-free interval of four weeks, animals received a test (IP) dose of ethanol (2 g/kg), and the adrenocortical and adrenomedullary responses were evaluated. Chronically ethanol-exposed animals showed tolerance to the stimulatory effect of ethanol in the pituitary-adrenal axis. Likewise, previously dependent rats showed tolerance to the increase in the activity of the adrenomedullary function induced by acute administration of the drug. Our results indicate that chronic ethanol ingestion can induce persistent changes after complete alcohol abstinence.

    Anhydrous ethanol is one of the biofuels produced today and it is a subset of renewable energy. It is considered to be an excellent alternative clean-burning fuel to gasoline. Anhydrous ethanol is commercially produced by either catalytic hydration of ethylene or fermentation of biomass. Any biological material that has sugar, starch or cellulose can be used as biomass for producing anhydrous ethanol. Since ethanol-water solution forms a minimum-boiling azeotrope of composition of 89.4 mol% ethanol and 10.6 mol% water at 78.2 C and standard atmospheric pressure, the dilute ethanol-water solutions produced by fermentation process can be continuously rectified to give at best solutions containing 89.4 mol% ethanol at standard atmospheric pressure. Therefore, special process for removal of the remaining water is required for manufacture of anhydrous ethanol. Various processes for producing anhydrous ethanol have been used/suggested. These include: (i) chemical dehydration process, (ii) dehydration by vacuum distillation process, (iii) azeotropic distillation process, (iv) extractive distillation processes, (v) membrane processes, (vi) adsorption processes and (vii) diffusion distillation process. These processes of manufacturing anhydrous ethanol have been improved continuously due to the increasingly strict requirements for quantity and quality of this product. The literature available on these processes is reviewed. These processes are also compared on the basis of energy requirements. (author)

    Full Text Available Orientation: The study focused on analysing the outreach performance of microfinance institutions (MFIs in providing critical services for the poor using innovative lending techniques within constrained environments. Research purpose: The study examined the trade-off relations between the depth and the breadth of outreach and identified institutional level factors that influence MFIs outreach in sub-Saharan Africa (SSA. Motivation for the study: MFIs continue to play critical roles in extending financial services to the poor and yet previous studies have not analysed comprehensively the dimensions of outreach necessary for financial inclusion. Research design, approach and methods: The study employed correlation analysis and random effects methodology to panel data regression analysis (619 observations, 71 MFIs across 10 countries to establish the trade-off relations and the determinants of outreach in SSA. Main findings: It was established that a trade-off exists between the depth of outreach (access to credit disbursement by poor clients and breadth of outreach (number of clients served. The results further revealed that gross loan portfolio, portfolio at risk, borrower per staff member, interest rate, and operating expenses to assets ratio are the main institutional determinants of MFIs outreach in SSA. Practical/managerial implications: The policy implication is that MFIs that concentrate efforts in reaching the relatively poor do so at the expense of reaching a large number of poor clients. We suggest that effective monitoring of depth and breadth and the adoption and implementation of cost-saving outreach technologies by MFIs could enable them to operate sustainably and efficiently. Contribution/value added: A major contribution of the study is the trade-off relations revealed between the depth of outreach and the breadth of outreach of MFIs which advances the outreach literature.

    The invention provides a method for producing ethanol, the method comprising establishing an atmosphere containing methanol forming catalyst and ethanol forming catalyst; injecting syngas into the atmosphere at a temperature and for a time sufficient to produce methanol; and contacting the produced methanol with additional syngas at a temperature and for a time sufficient to produce ethanol. The invention also provides an integrated system for producing methanol and ethanol from syngas, the system comprising an atmosphere isolated from the ambient environment; a first catalyst to produce methanol from syngas wherein the first catalyst resides in the atmosphere; a second catalyst to product ethanol from methanol and syngas, wherein the second catalyst resides in the atmosphere; a conduit for introducing syngas to the atmosphere; and a device for removing ethanol from the atmosphere. The exothermicity of the method and system obviates the need for input of additional heat from outside the atmosphere.

  9. The Role of Cellulosic Ethanol in Transportation

    2007-10-01

    Petroleum provides essentially all of the energy used today in the transportation sector. To reduce this dependence on fossil energy, other fuels are beginning to be used, notably ethanol and biodiesel. Almost all fuel ethanol is produced by the conversion of corn grain to starch with subsequent fermentation to ethanol. In 2006, almost 5 billion gallons of fuel ethanol were produced, which used 17% of domestic corn production. The DOE has a goal to displace 30% of motor gasoline demand or 60 billion gallons per year by 2030. To achieve this goal, production of ethanol from lignocellulosic sources (e.g., agricultural residues, forest residues, and dedicated energy crops) is needed. This paper will describe the production of cellulosic ethanol as well as the issues and benefits associated with its production.

    The Solar System Ambassadors Program is a public outreach program designed to work with motivated volunteers across the nation. These competitively selected volunteers organize and conduct public events that communicate exciting discoveries and plans in Solar System research, exploration and technology through non-traditional forums. In 2001, 206 Ambassadors from almost all 50 states bring the excitement of space to the public. Ambassadors are space enthusiasts, who come from all walks of life. Last year, Ambassadors conducted almost 600 events that reached more than one-half million people in communities across the United States. The Solar System Ambassadors Program is sponsored by the Jet Propulsion Laboratory (JPL) in Pasadena, California, an operating division of the California Institute of Technology (Caltech) and a lead research and development center for the National Aeronautics and Space Administration (NASA). Participating JPL organizations include Cassini, Galileo, STARDUST, Outer Planets mission, Genesis, Ulysses, Voyager, Mars missions, Discovery missions NEAR and Deep Impact, Deep Space Network, Solar System Exploration Forum and the Education and Public Outreach Office. Each Ambassador participates in on-line (web-based) training sessions that provide interaction with NASA scientists, engineers and project team members. As such, each Ambassador's experience with the space program becomes personalized. Training sessions provide Ambassadors with general background on each mission and educate them concerning specific mission milestones, such as launches, planetary flybys, first image returns, arrivals, and ongoing key discoveries. Additionally, projects provide limited supplies of materials, online resource links and information. Integrating volunteers across the country in a public-engagement program helps optimize project funding set aside for education and outreach purposes, establishing a nationwide network of regional contacts.

    One objective of the "Ocean Autonomous Observation" team of the Laboratory of Oceanography of Villefranche-sur-mer is to develop new means to outreach our science activities to various audiences. Besides the scientific community, this includes students and targets the general public, school pupils, and stakeholders. In this context, we have acquired a digital video globe with tactile capabilities and we will present here the various applications that we have been developing. A first type of products concerns the visualization of oceanic properties (SST, salinity, density, Chla, O2, NO3, irradiance) by diving from the surface (generally from satellite data) into the Ocean interior (through the use of global data bases, Argo, WOA). In second place, specific applications deal with surface animations allowing highlighting the seasonality of some properties (Chla, SST, ice cover, currents; based on satellite as well as modeling outputs). Finally, we show a variety of applications developed using the tactile functionality of the spherical display. In particular real-time vertical profiles acquired by Bio-Argo floats become directly accessible for the entire open ocean. Such a new tool plus its novel applications has been presented to school children, and to the wider public (at the so-called "fête de la science") as well as to potential sponsors of our science-outreach activities. Their feedback has always been highly positive and encouraging in terms of impact. From the scientists point of view, the use of this new support can easily compete with the classical PowerPoint, is much more attractive and fun and undeniably helps to outreach the various aspects of our pluridisciplinary science.

    Since 2005, Europlanet has provided a framework to bring together Europe's fragmented planetary science community. The project has evolved through a number of phases into a self-sustaining membership organization. Now, Europlanet is launching a new Research Infrastructure (RI) funded through the European Commission's Horizon 2020 programme that, for the next four years, will provide support, services, access to facilities, new research tools and a virtual planetary observatory. Europlanet 2020 RI's Impact Through Outreach and Education (IOE) activities aim to ensure that the work of Europlanet and the community it supports is known, understood and used by stakeholders, and that their inputs are taken into account by the project. We will engage citizens, policy makers and potential industrial partners across Europe with planetary science and the opportunities that it provides for innovation, inspiration and job creation. We will reach out to educators and students, both directly and through partner networks, to provide an interactive showcase of Europlanet's activities e.g through live link-ups with scientists participating in planetary analogue field trips, educational video "shorts" and through using real planetary data from the virtual observatory in comparative planetology educational activities. We will support outreach providers within the planetary science community (e.g. schools liaison officers, press officers, social media managers and scientists active in communicating their work) through meetings and best practice workshops, communication training sessions, an annual prize for public engagement and a seed-funding scheme for outreach activities. We will use traditional and social media channels to communicate newsworthy results and activities to diverse audiences not just in Europe but also around the globe.

    1994-01-01

    Since the mid-1980's, the Institutional and External Affairs staff of the Yucca Mountain Site Characterization Project (YMP) has developed, coordinated, and maintained various public outreach programs to carry out the YMP's open door policy of keeping local communities informed. However, public involvement first requires public knowledge and, therefore, various information programs have been established over the past few years. First came the speakers bureau program, then the exhibits and science centers; and then came the tours and school district educational programs. All these programs were geared toward teaching the mainstream general public about the YMP and issues related to things nuclear. Today, the YMP outreach programs are established and known and the demand from the public has seen a shift. Over 150 top scientists and staff from around the country who have come to work at the YMP have joined the outreach participant pool to speak to the public not only about Yucca Mountain, but about their areas of expertise as well. For this reason, the public has realized a great opportunity for a general science and engineering education resource -- the YMP staff themselves. In a panel discussion, open-quotes Trust and credibility: The central issueclose quotes, proceedings of the National Conference on Risk Communication, it was shown that university professors and science teachers were among the most trusted individuals in terms of public perception and that government staff and contractors the least trusted. However, when you utilize the core educated knowledge of a YMP scientist in order to teach general science and math, you have, to some extent, placed that individual in an educational role and thus increased trust. The YMP scientists enjoy talking about their general science knowledge and we have found that the public likes to hear about it too

    Anaerobic digestion of whole stillage from a dry-grind corn-based ethanol plant was evaluated by batch and continuous-flow digesters under thermophilic and mesophilic conditions. At whole corn stillage concentrations of 6348 to 50,786 mg total chemical oxygen demand (TCOD)/L, at standard temperature (0 °C) and pressure (1 atm), preliminary biochemical methane potential assays produced 88±8 L (49±5 L CH4) and 96±19 L (65±14 L CH4) biogas per L stillage from mesophilic and thermophilic digesters, respectively. Continuous-flow studies for the full-strength stillage (TCOD=254 g/L) at organic loadings of 4.25, 6.30 and 9.05 g TCOD/L days indicated unstable performance for the thermophilic digester. Among the sludge retention times (SRTs) of 60, 45 and 30 days tested, the mesophilic digestion was successful only at 60 days-SRT which does not represent a practical operation time for a large scale bioethanol plant. Future laboratory studies will focus on different reactor configurations to reduce the SRT needed in the digesters. Copyright © 2010 Elsevier Ltd. All rights reserved.

  16. Russia’s Monroe Doctrine: peacekeeping, peacemaking, or imperial outreach?

    Directory of Open Access Journals (Sweden)

    Teresa Rakowska-Harmstone

    2014-06-01

    Full Text Available The article discusses the important changes in the Russian foreign policy doctrines that occurred in the beginnings of the 1990s, after the collapse of the Soviet Union. The Author argues that the officially claimed devotion to peacemaking and peacekeeping are in fact manifestations of the Russian imperial outreach. The model of international relations promoted by Moscow in fact resembles the American 19th century Monroe Doctrine. Thus, the foreign policy doctrine and the potential national conflicts in the post-Soviet territory may become triggers for Russian actions aiming at restoring the Russian Empire.

  17. Outrageous Outreach — Unconventional Ways of Communicating Science

    Science.gov (United States)

    Sandu, O.; Christensen, L. L.

    2011-07-01

    The golden rule of communication, advertising, public relations and marketing is "follow your target group". In this article, we look at how this mantra is applied in science communication and public outreach. Do we really follow our target groups? Do we regularly research the behaviour, interests and preferences of the individuals behind the demographic categories? Or do we just believe that we are following them when in fact we are "preaching to the converted" — the demographic group that is already intrinsically interested in science and actively scours the science sections of the national newspapers?

    Reynolds, Sandra L; Haley, William E; Hyer, Kathryn

    2007-01-01

    As state budget allocations for higher education decrease, "specialty" programs such as gerontology must continually demonstrate their productivity. State and private universities increasingly rely on student credit hours (SCH) or tuition generated, which is making it difficult for many gerontology programs to expand. The School of Aging Studies at the University of South Florida has achieved a 236% increase in annual SCH productivity over the past 5 years by methods including qualifying courses for university liberal arts requirements, and designing and cross-listing interdisciplinary courses. This increased productivity has supported program expansion and led to beneficial outreach to students from diverse majors.

    Prabhu, Radha; Browne, Mark Oakley

    2007-04-01

    A recovery-based outreach program for people with severe mental illness in regional Victoria is described. The paper covers a description of the program, the services provided and outcomes achieved. The program emphasized active collaboration between patients and clinicians as outlined in the collaborative recovery model and recognized that recovery from mental illness is an individual, personal process. The program provided service to 108 people over 3 years and had a positive impact on clinicians, patients and carers. The benefits of recovery orientation, multidisciplinary teams, collaborative relationships and carer involvement are discussed. The paper highlights the need for a focus on recovery and comprehensive care for people with severe mental illness.

  20. [Street Outreach Offices: visibility, invisibility, and enhanced visibility].

    Science.gov (United States)

    Hallais, Janaína Alves da Silveira; Barros, Nelson Filice de

    2015-07-01

    This article discusses care for street people from a socio-anthropological perspective, using participant observation conducted with a team from a street outreach project. Based on observations, street people are historically viewed as marginal and rarely obtain access to health services, thus making them invisible to the Brazilian Unified National Health System. Brazil's National Policy for the Homeless provides for their access to health care, but such care is not always guaranteed in practice, because health services and professionals have little experience in dealing with homeless persons. The study concludes that enhanced visibility is needed to ensure care for people living on the street, establishing a therapeutic bond that deconstructs stigmatizing practice.

  1. Bones, Bodies, and Blogs: Outreach and Engagement in Bioarchaeology

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available Surprisingly few bioarchaeology blogs currently exist, but their numbers belie their reach. In this article, we survey the ecology of the bioarchaeology blogosphere and address the impact of blogging in bioarchaeology, specifically addressing its utility in outreach and public engagement. In providing specific examples from our collective decade of blogging and from other bioarchaeology bloggers, we provide best practices to encourage bioarchaeologists who may want to add their voices to this sphere. The difficulties and potential issues of blogging bioarchaeology are far outweighed by the benefits of expanding communication and furthering disciplinary engagement in an increasingly digital world. We call on bioarchaeologists to be protagonists and advocates of our discipline.

    2011-01-01

    Successive studies attempting to clarify national aspects of ethanol demand have assisted policy makers and producers in defining strategies, but little information is available on the dynamic of regional ethanol markets. This study aims to analyze the characteristics of ethanol demand at the regional level taking into account the peculiarities of the developed center-south and the developing north-northeast regions. Regional ethanol demand is evaluated based on a set of market variables that include ethanol price, consumer's income, vehicle stock and prices of substitute fuels; i.e., gasoline and natural gas. A panel cointegration analysis with monthly observations from January 2003 to April 2010 is employed to estimate the long-run demand elasticity. The results reveal that the demand for ethanol in Brazil differs between regions. While in the center-south region the price elasticity for both ethanol and alternative fuels is high, consumption in the north-northeast is more sensitive to changes in the stock of the ethanol-powered fleet and income. These, among other evidences, suggest that the pattern of ethanol demand in the center-south region most closely resembles that in developed nations, while the pattern of demand in the north-northeast most closely resembles that in developing nations. - Research highlights: → Article consists of a first insight on regional demand for ethanol in Brazil. → It proposes a model with multiple fuels, i.e., hydrous ethanol, gasohol and natural gas. → Results evidence that figures for regional demand for ethanol differ amongst regions and with values reported for national demand. → Elasticities for the center-south keep similarities to patterns for fuel demand in developed nations while coefficients for the north-northeast are aligned to patterns on developing countries.

    Tomie, Arthur; Wong, Karlvin; Apor, Khristine; Patterson-Buckendahl, Patricia; Pohorecky, Larissa A

    2003-11-01

    In two studies, we evaluated the effects of ethanol concentration and trial spacing on Pavlovian autoshaping of ethanol drinking in rats. In these studies, the brief insertion of an ethanol sipper conditioned stimulus (CS) was followed by the response-independent presentation of food unconditioned stimulus (US), inducing sipper CS-directed drinking conditioned responses (CRs) in all rats. In Experiment 1, the ethanol concentration in the sipper CS [0%-16% volume/volume (vol./vol.), in increments of 1%] was systematically increased within subjects across autoshaping sessions. Groups of rats received sipper CS-food US pairings (Paired/Ethanol), a CS-US random procedure (Random/Ethanol), or water sipper CS paired with food US (Paired/Water). In Experiment 2, saccharin-fading procedures were used to initiate, in the Ethanol group, drinking of 6% (vol./vol.) ethanol in 0.1% saccharin or, in the Water group, drinking of tap water in 0.1% saccharin. After elimination of saccharin, and across days, the duration of access to the sipper CS during each autoshaping trial was increased (5, 10, 12.5, 15, 17.5, and 20 s), and subsequently, across days, the duration of the mean intertrial interval (ITI) was increased (60, 90, 120, and 150 s). In Experiment 1, Paired/Ethanol and Random/Ethanol groups showed higher intake of ethanol, in terms of grams per kilogram of body weight, at higher ethanol concentrations, with more ethanol intake recorded in the Paired/Ethanol group. In Experiment 2, the Ethanol group drank more than was consumed by the Water group, and, for both groups, fluid intake increased with longer ITIs. Results support the suggestion that autoshaping contributes to sipper CS-directed ethanol drinking.

    Alcoholism induces folate deficiency and increases the risk for embryonic anomalies. However, the interplay between ethanol exposure and embryonic folate status remains unclear. To investigate how ethanol exposure affects embryonic folate status and one-carbon homeostasis, we incubated zebrafish embryos in ethanol and analyzed embryonic folate content and folate enzyme expression. Exposure to 2% ethanol did not change embryonic total folate content but increased the tetrahydrofolate level app...

  9. Mixed waste paper to ethanol fuel

    The objectives of this study were to evaluate the use of mixed waste paper for the production of ethanol fuels and to review the available conversion technologies, and assess developmental status, current and future cost of production and economics, and the market potential. This report is based on the results of literature reviews, telephone conversations, and interviews. Mixed waste paper samples from residential and commercial recycling programs and pulp mill sludge provided by Weyerhauser were analyzed to determine the potential ethanol yields. The markets for ethanol fuel and the economics of converting paper into ethanol were investigated.

    Derivatives of the newly discovered microorganism Thermoanaerobacter ethanolicus which under anaerobic and thermophilic conditions continuously ferment substrates such as starch, cellobiose, glucose, xylose and other sugars to produce recoverable amounts of ethanol solving the problem of fermentations yielding low concentrations of ethanol using the parent strain of the microorganism Thermoanaerobacter ethanolicus are disclosed. These new derivatives are ethanol tolerant up to 10% (v/v) ethanol during fermentation. The process includes the use of an aqueous fermentation medium, containing the substrate at a substrate concentration greater than 1% (w/v).

    1986-11-01

    Selected wine yeasts were tested for their ethanol and sugar tolerance, and for their fermentative capacity. Growth (..mu..) and fermentation rates (..nu..) were increasingly inhibited by increasing ethanol and glucose concentrations, ''flor'' yeasts being the least inhibited. Except in the latter strains, the ethanol production rate was accelerated by adding the glucose stepwise. The best fermenting strains selected in laboratory medium were also the best at fermenting molasses. Invertase activity was not a limiting step in ethanol production, ..nu.. being accelerated by supplementing molasses with ammonia and biotine, and by cell recycle.

    As the science operations center for the Hubble Space Telescope and the James Webb Space Telescope, the Space Telescope Science Institute (STScI) is uniquely positioned to captivate the imagination and inspire learners of all ages in humanity’s quest to understand fundamental questions about our universe and our place in it. This presentation will provide an overview of the impact of the STScI’s Office of Public Outreach’s efforts to engage students, educators, and the public in exploring the universe through audience-based news, education, and outreach programs.At the heart of our programs lies a tight coupling of scientific, education, and communications expertise. By partnering scientists and educators, we assure current, accurate science content and education products and programs that are classroom-ready and held to the highest pedagogical standards. Likewise, news and outreach programs accurately convey cutting-edge science and technology in a way that is attuned to audience needs. The combination of Hubble’s scientific capabilities, majestic imagery, and our deep commitment to create effective programs to share Hubble science with the education community and the public, has enabled the STScI Office of Public Outreach programs to engage 6 million students and ½ million educators per year, and 24 million online viewers per year. Hubble press releases generate approximately 5,000 online news articles per year with an average circulation of 125 million potential readers per press release news story. We will also share how best practices and lessons learned from this long-lived program are already being applied to engage a new generation of explorers in the science and technology of the James Webb Space Telescope.

    Whole cell immobilization has been studied in the laboratory during the last few years as a method to improve the performance and economics of most fermentation processes. Among the various techniques available for cell immobilization, methods that provide generation of a biofilm offer reduced diffusional resistance, high productivities, and simple operation. This paper reviews some of the important aspects of biofilm reactors for ethanol production, including reactor start-up, steady state behavior, process stability, and mathematical modeling. Special emphasis is placed on covalently bonded Saccharomyces cerevisiae in packed bed reactors.

    After hepatectomy, 7%-19% of patients are readmitted within 30 days, accounting for substantial cost and poor patient experience. The purpose of this study was to analyze the impact of a proactive outreach intervention on readmissions. Consecutive patients undergoing hepatectomy by a single surgeon 2012-2016 were identified in a prospectively maintained database. In August 2013 a postoperative intervention was implemented; an advanced practice provider called each patient within 72 hours of discharge. Readmission rates were compared pre- and postintervention using standard statistics. Two hundred thirty-one patients met the inclusion criteria and major hepatectomy was performed in 45.5% of patients. Although the complication rate was similar (25.0% preintervention and 19.4% postintervention, P = .324), readmissions within 30 days of operation decreased from 14.5% pre- to 6.5% postintervention (P = .046). Approximately 30% of outreach interactions required outpatient intervention. Factors associated with readmission on univariate analysis included increased operative time (P = .007), major hepatectomy (P = .012), hemi or extended hepatectomy (P = .032), second stage operation (P = .031), bile leak (P = 0.022), and any complication/modified Accordion complication ≥ 3 within 30 days (P work created by the intervention is likely offset by decreased inpatient care needs and costs. Identification of high-risk populations and application of technology are likely to lead to further improvements. Copyright © 2017 Elsevier Inc. All rights reserved.

  17. Floating Classroom Outreach as an Introduction to Ocean Studies

    McFadden, M.

    2016-02-01

    Many children and young adults living within only one hour of the coast never have the opportunity to explore a beach or go out on a boat because of financial challenges or lack of transportation.These types of experiences are the spark that helped many ocean scientists become fascinated with the ocean and later pursue a career related to the ocean. This presentation will discuss a variety of outreach projects and the efficacy of each. Projects vary in age, complexity and cost. These projects include a Beach Clean-Up open to students and their families at a community college organized by a campus volunteer group with a focus on social issues, a Marine Biology and Physical Oceanography class joint floating classroom trip open to college students to introduce non-STEM students to marine science in an exciting setting, and an education outreach trip for 8-12 years old children from the Boys and Girls Club in Newport, RI in collaboration with The International SeaKeepers Society, a non-profit that facilitates ocean research and education by working closely with the yachting community. Emphasis on environmental education in the U.S. has grown considerably over recent years, and the development of unique and innovative approaches to hands-on marine science education are needed to excite students to explore the marine environment and care about environmental stewardship.

  18. Quality of Informal Housing: Contributions from University Outreach

    Directory of Open Access Journals (Sweden)

    Helmuth Ramos Calonge

    2016-02-01

    Full Text Available The main purpose of this article is to reflect on the quality and habitable conditions of informal housing and to propose two ways of contributing to its improvement from university outreach. Two outreach exercises carried out by the School of Habitat Sciences from La Salle University are explained, together with two organizations dedicated to work for the improvement of the living conditions of the vulnerable population. One of them involves integral improvement actions in a neighborhood, which led to conducting remodeling and construction work accompanied by social workers and psychologists; the other one was to design new training methodologies for foremen; each case includes particular reflections and, in the end, general reflections and conclusions inherent to the quality and habitability of informal housing. It is concluded, in general terms, that the quality and habitability of affordable, informal housing is poor, and it is highlighted that the first step for improving it must be taken by the user or owner, based on their appropriation of habitat, either at the individual, family or community level; in other words, better living conditions will only be achieved when the owner and the community decide so.

    Since 1995, when National Geographic Information Project began, we have great advance in mapping itself and information service on the earth surface in Korea whether paper maps or online service map. By reviewing geological and mine-related information service in current and comparisons of demands, GEBCO outreach master plan has been prepared. Information service cannot be separated from data production and on dissemination policies. We suggest the potential impact of the changes in information technologies such as mobile service and data fusion, and big data on GEBCO maps based. Less cost and high performance in data service will stimulate more information service; therefore it is necessary to have more customer-oriented manipulation on the data. By inquiring questionnaire, we can draw the potential needs on GEBCO products in various aspects: such as education, accessibility. The gap between experts and non-experts will decrease by digital service from the private and public organizations such as international academic societies since research funds and policies tend to pursue "openness" and "interoperability" among the domains. Some background why and how to prepare outreach activities in GEBCO will be shown.

  20. Technology information transfer in public outreach - a new approach

    1994-01-01

    The timely and accurate dissemination to the public of information derived from the site characterization activities on the Yucca Mountain Site Characterization Project (YMP) has sometimes been difficult to achieve. The YMP has many participants who are involved in the gathering and analysis of scientific and engineering data for site characterization. The diversity of the scientific disciplines involved, the uncentralized location of the participant organizations, the difficulty of being able to ask the right questions of the right people, and the translation of technical jargon into understandable terms are but a few of the challenges. The public outreach program of the YMP has done an excellent job of compiling and distributing information over the past few years, but, with the diversity and expansion of field activities in the last two years, the job has become more formidable. A new approach to help resolve this obstacle was instituted in April of 1993, and has been successful in achieving a much more timely and user-friendly discussion of technical information for the public. What is the new approach? The assignment of a technical expert to the public outreach staff whose job is to know what is going on, who is doing what, and what the results are. Based on that knowledge, factual summaries can be generated rapidly and presented to the public in the context of the overall project goals and in a form suitable for a wide range of audiences

    2016-04-01

    The ATLAS Education & Outreach project has, over the years, developed a strong reputation for supporting innovation. Animated event displays, musical CDs, 3d movies, 3-storey murals, photo books, data sonifications, multi-media art installations, pub slams, masterclasses, documentaries, pop-up books, LEGO® models, and virtual visits are among the many diverse methods being exploited to communicate to the world the goals and accomplishments of the ATLAS Experiment at CERN. This variety of creativity and innovation does not pop out of a vacuum. It requires underlying motivation by the collaboration to communicate with the public; freedom and encouragement to do so in a creative manner; and a support structure for developing, implementing and promoting these activities. The ATLAS Outreach project has built this support structure on a well-defined communication plan, high-quality content, and effective delivery platforms. Most importantly, implementation of the program has been based on the effective engagement of the participating institutes and other key partners, not only to leverage modest human resources and funding, but also to take advantage of the rich imagination and inspiration of a diverse, global human collaboration. We present our current plan, on-going activities, and a few more fun innovations for the future.

    AstroMcGill was founded in 2011 by an enthusiastic group of undergraduate students, graduate students and post-doctoral fellows. It serves as the education and public outreach (EPO) branch of the astronomy group within the Physics Department at McGill University in Montreal, Quebec. Over the last five years, AstroMcGill has grown from organizing sporadic visits in a couple primary schools to running a successful inquiry-based outreach programme for grade 4-6 students, the McGill Space Explorers. During the same time span, the attendance at public AstroNight lectures ramped up from attracting a few dozen people to over 500 people each month. We will highlight the recent successes of the programme and our best guesses for the reasons behind this success. We will also discuss the challenges of working in a bilingual city as we juggle our majority anglophone volunteers, a mandatory french science curriculum for primary school children and the (somewhat) overlapping English- and French-speaking communities in the city.

    The BIG Bell test uses the input from the Bellsters, self-selected human participants introducing zeros and ones through an online videogame, to perform a suite of quantum physics experiments. In this talk, we will explore the videogame, the data infrastructure and the outreach efforts of the BIG Bell test collaboration. First, we will discuss how the game was designed so as to eliminate possible feedback mechanisms that could influence people's behavior. Second, we will discuss the cloud architecture design for scalability as well as explain how we sent each individual bit from the users to the labs. Also, and using all the bits collected via the BIG Bell test interface, we will show a data analysis on human randomness, e.g. are younger Bellsters more random than older Bellsters? Finally, we will talk about the outreach and communication efforts of the BIG Bell test collaboration, exploring both the social media campaigns as well as the close interaction with teachers and educators to bring the project into classrooms.

    How does a scientist find herself standing before a group of lively third-graders? She may be personally motivated-seeking to improve public understanding of scientific issues and the nature of science, or to see her own children receive a good science education-or perhaps she simply enjoys this kind of work [Andrews et al., 2005; Kim and Fortner, 2008]. In addition to internal motivating factors, federal funding agencies have begun to encourage scientists to participate in education and outreach (E/O) related to their research, through NASA program requirements for such activities (see ``Implementing the Office of Space Science Education/Public Outreach Strategy,'' at http://spacescience.nasa.gov/admin/pubs/edu/imp_plan.htm) and the U.S. National Science Foundation's increased emphasis on ``broader impacts'' in merit review of research proposals (see http://www.nsf.gov/pubs/2003/nsf032/bicexamples.pdf).

  1. Dialectical dividends: fostering hybridity of new pedagogical practices and partnerships in science education and outreach

    Martins Gomes, Diogo; McCauley, Veronica

    2016-09-01

    Science literacy has become socially and economically very important. European countries stress that science graduates are fundamental for economic growth. Nevertheless, there is a declining student participation in science. In response, there has been a call to change the way science is taught in schools, which focuses on inquiry methods rooted in constructivism. Universities and other organisations have responded by developing outreach programmes to improve student engagement in science. Given this context, there is a necessity for research to ascertain if this new relationship between outreach and education is worthwhile. This study examines and compares primary teachers and outreach practitioners understanding and perceptions of constructivist science pedagogy, in an effort to understand the potential of a teacher-outreach partnership. For this, qualitative and quantitative methods were employed, taking a dialectic pragmatic stance. Contradicting the recurrent view, teachers and outreach providers revealed favourable views in relation to constructivism, despite recognising barriers to its implementation. These results support a partnership between teachers and outreach practitioners and the realisation of the hybrid role of each participant. The results also reveal an important dynamic in outreach access to schools. Specifically, the outreach connected teachers acted as gatekeepers by negotiating access into their colleagues classrooms.

    2017-01-07

    The purpose of the study is to explore the reasons why specialist doctors travel to provide regular rural outreach services, and whether reasons relate to (1) salaried or private fee-for-service practice and (2) providing rural outreach services in more remote locations. A national cross-sectional study of specialist doctors from the Medicine in Australia: Balancing Employment and Life (MABEL) survey in 2014 was implemented. Specialists providing rural outreach services self-reported on a 5-point scale their level of agreement with five reasons for participating. Chi-squared analysis tested association between agreement and variables of interest. Of 567 specialists undertaking rural outreach services, reasons for participating include to grow the practice (54%), maintain a regional connection (26%), provide complex healthcare (18%), healthcare for disadvantaged people (12%) and support rural staff (6%). Salaried specialists more commonly participated to grow the practice compared with specialists in fee-for-service practice (68 vs 49%). This reason was also related to travelling further and providing outreach services in outer regional/remote locations. Private fee-for-service specialists more commonly undertook outreach services to provide complex healthcare (22 vs 14%). Specialist doctors undertake rural outreach services for a range of reasons, mainly to complement the growth and diversity of their main practice or maintain a regional connection. Structuring rural outreach around the specialist's main practice is likely to support participation and improve service distribution.

    Ren, Xiuping; Zhou, Bo; Wang, Chunlei

    2012-07-14

    The dewetting transitions of two hydrophobic plates immersed in pure water, aqueous ethanol solutions with concentrations from 25% to 90%, and pure ethanol were investigated by molecular dynamics simulations, where the dewetting transition was analogous to a first-order phase transition from liquid to vapor. It was found that the dewetting transitions occurred except that in the pure ethanol system. Although the ethanol molecules prefer to locate in the vicinity of the two plates, the inter-plate region is unfavorable for water molecules, due to losing more than one hydrogen bond. Moreover, each inter-plate water molecule forms hydrogen bonds on average with about two ethanol molecules. These intermolecular hydrogen bonds cause water and ethanol to cooperatively fill or exit the inter-plate region. Thus, water molecules play a more important role in the inter-plate filling/empty process, and induce the ethanol dewetting transition. Our results provide insight into the effect of water on the ethanol dewetting phenomena.

  10. Beyond commonplace biofuels: Social aspects of ethanol

    International Nuclear Information System (INIS)

    Ribeiro, Barbara Esteves

    2013-01-01

    Biofuels policies and projects may lead to environmental, economic and social impacts. A number of studies point out the need to deliver comprehensive sustainability assessments regarding biofuels, with some presenting analytical frameworks that claim to be exhaustive. However, what is often found in the literature is an overexploitation of environmental and economic concerns, by contrast to a limited appraisal of the social aspects of biofuels. Building on a systematic review of the peer-reviewed literature, this paper discusses the social constraints and strengths of ethanol, with regard to the product's lifecycle stages and the actors involved. Its objective is to contribute to the development of social frameworks to be used in assessing the impact of ethanol. Main findings indicate that ethanol developments can increase the levels of social vulnerability, although there is little evidence in the literature regarding the positive and negative social impacts of 1st-generation ethanol and potential impacts of cellulosic ethanol. Further work is needed on the formulation of social criteria and indicators for a comprehensive sustainability assessment of this biofuel. Policy makers need to internalise the social dimension of ethanol in decision-making to prevent public opposition and irreversible social costs in the future. - Highlights: ► The literature lacks evidence on the social impacts of ethanol. ► Further work is needed on social criteria and indicators for assessment. ► Ethanol developments can increase the levels of social vulnerability. ► Decision-making should internalise the social dimension of biofuels sustainability

  13. Pavlovian conditioning with ethanol: sign-tracking (autoshaping), conditioned incentive, and ethanol self-administration.

    Science.gov (United States)

    Krank, Marvin D

    2003-10-01

    Conditioned incentive theories of addictive behavior propose that cues signaling a drug's reinforcing effects activate a central motivational state. Incentive motivation enhances drug-taking and drug-seeking behavior. We investigated the behavioral response to cues associated with ethanol and their interaction with operant self-administration of ethanol. In two experiments, rats received operant training to press a lever for a sweetened ethanol solution. After operant training, the animals were given Pavlovian pairings of a brief and localized cue light with the sweetened ethanol solution (no lever present). Lever pressing for ethanol was then re-established, and the behavioral effects of the cue light were tested during an ethanol self-administration session. The conditioned responses resulting from pairing cue lights with the opportunity to ingest ethanol had three main effects: (1) induction of operant behavior reinforced by ethanol, (2) stimulation of ethanol-seeking behavior (magazine entries), and (3) signal-directed behavior (i.e., autoshaping, or sign-tracking). Signal-directed behavior interacted with the other two effects in a manner predicted by the location of the cue light. These conditioned responses interact with operant responding for ethanol reinforcement. These findings demonstrate the importance of Pavlovian conditioning effects on ethanol self-administration and are consistent with conditioned incentive theories of addictive behavior.

    1993-07-01

    The effects of intravenous ethanol and ethanol plus furosemide on pancreatic capillary blood flow (PCBF) were investigated using a laser-Doppler flowmeter. Forty Sprague-Dawley male rats were divided into 4 groups: (1) control, (2) 80% ethanol, (3) 80% ethanol plus furosemide, and (4) furosemide. Mean arterial blood pressure and heart rate were monitored. Levels of serum amylase, calcium, electrolytes, ethanol, and furosemide (groups 3 and 4) were measured, and samples of pancreatic tissue were obtained. The ethanol and furosemide levels were statistically different (p 0.05) between groups 1 and 4. Histopathologic analysis revealed swollen acini in group 2 and sparse focal necrosis without acinar swelling in group 3. The depressant effect of ethanol on PCBF may be the result of its direct action on pancreatic cells causing edema and capillary compression rather than on primary vascular control mechanisms that adjust blood flow. Furosemide counters this effect.

  15. The ethanol pathway from Thermoanaerobacterium saccharolyticum improves ethanol production in Clostridium thermocellum.

    2017-07-01

    Clostridium thermocellum ferments cellulose, is a promising candidate for ethanol production from cellulosic biomass, and has been the focus of studies aimed at improving ethanol yield. Thermoanaerobacterium saccharolyticum ferments hemicellulose, but not cellulose, and has been engineered to produce ethanol at high yield and titer. Recent research has led to the identification of four genes in T. saccharolyticum involved in ethanol production: adhE, nfnA, nfnB and adhA. We introduced these genes into C. thermocellum and observed significant improvements to ethanol yield, titer, and productivity. The four genes alone, however, were insufficient to achieve in C. thermocellum the ethanol yields and titers observed in engineered T. saccharolyticum strains, even when combined with gene deletions targeting hydrogen production. This suggests that other parts of T. saccharolyticum metabolism may also be necessary to reproduce the high ethanol yield and titer phenotype in C. thermocellum.

  17. Production of ethanol from wheat straw

    Directory of Open Access Journals (Sweden)

    Smuga-Kogut Małgorzata

    2015-09-01

    Full Text Available This study proposes a method for the production of ethanol from wheat straw lignocellulose where the raw material is chemically processed before hydrolysis and fermentation. The usefulness of wheat straw delignification was evaluated with the use of a 4:1 mixture of 95% ethanol and 65% HNO3 (V. Chemically processed lignocellulose was subjected to enzymatic hydrolysis to produce reducing sugars, which were converted to ethanol in the process of alcoholic fermentation. Chemical processing damages the molecular structure of wheat straw, thus improving ethanol yield. The removal of lignin from straw improves fermentation by eliminating lignin’s negative influence on the growth and viability of yeast cells. Straw pretreatment facilitates enzymatic hydrolysis by increasing the content of reducing sugars and ethanol per g in comparison with untreated wheat straw.

    to redirect the metabolism of LAB model organism Lactococcus lactis toward ethanol production. Codon-optimized Zymomonas mobilis pyruvate decarboxylase (PDC) was introduced and expressed from synthetic promoters in different strain backgrounds. In the wild-type L. lactis strain MG1363 growing on glucose, only...... small amounts of ethanol were obtained after introducing PDC, probably due to a low native alcohol dehydrogenase activity. When the same strains were grown on maltose, ethanol was the major product and lesser amounts of lactate, formate, and acetate were formed. Inactivating the lactate dehydrogenase...... genes ldhX, ldhB, and ldh and introducing codon-optimized Z. mobilis alcohol dehydrogenase (ADHB) in addition to PDC resulted in high-yield ethanol formation when strains were grown on glucose, with only minor amounts of by-products formed.

  1. Policy Uncertainty and the US Ethanol Industry

    Directory of Open Access Journals (Sweden)

    Jason P. H. Jones

    2017-11-01

    Full Text Available The Renewable Fuel Standard (RFS2, as implemented, has introduced uncertainty into US ethanol producers and the supporting commodity market. First, the fixed mandate for what is mainly cornstarch-based ethanol has increased feedstock price volatility and exerts a general effect across the agricultural sector. Second, the large discrepancy between the original Energy Independence and Security Act (EISA intentions and the actual RFS2 implementation for some fuel classes has increased the investment uncertainty facing investors in biofuel production, distribution, and consumption. Here we discuss and analyze the sources of uncertainty and evaluate the effect of potential RFS2 adjustments as they influence these uncertainties. This includes the use of a flexible, production dependent mandate on corn starch ethanol. We find that a flexible mandate on cornstarch ethanol relaxed during drought could significantly reduce commodity price spikes and alleviate the decline of livestock production in cases of feedstock production shortfalls, but it would increase the risk for ethanol investors.

    2002-01-01

    In July 2002, the U.S. Congress approved Yucca Mountain in Nevada as the nation's first long-term geologic repository site for spent nuclear fuel and high-level radioactive waste. This major milestone for the country's high-level radioactive waste disposal program comes after more than twenty years of scientific study and intense public interaction and outreach. This paper describes public interaction and outreach challenges faced by the U.S. Department of Energy's (DOE) Yucca Mountain Project in the past and what additional communication strategies may be instituted following the July 2002 approval by the U.S. Congress to develop the site as the nation's first long-term geologic repository for spent nuclear fuel and high-level radioactive waste. The DOE public involvement activities were driven by two federal regulations--the National Environmental Policy Act (NEPA) and the Nuclear Waste Policy Act (NWPA) of 1982, as amended. The NEPA required that DOE hold public hearings at key points in the development of an Environmental Impact Statement (EIS) and the NWPA required the agency to conduct public hearings in the vicinity of the site prior to making a recommendation regarding the site's suitability. The NWPA also provided a roadmap for how DOE would interact with affected units of government, which include the state of Nevada and the counties surrounding the site. Because the Department anticipated and later received much public interest in this high-profile project, the agency decided to go beyond regulatory-required public involvement activities and created a broad-based program that implemented far-reaching public interaction and outreach tactics. Over the last two decades, DOE informed, educated, and engaged a myriad of interested local, national, and international parties using various traditional and innovative approaches. The Yucca Mountain Project's intensive public affairs initiatives were instrumental in involving the public, which in turn resulted in

The NWPA also provided a roadmap for how DOE would interact with affected units of government, which include the state of Nevada and the counties surrounding the site. Because the Department anticipated and later received much public interest in this high-profile project, the agency decided to go beyond regulatory-required public involvement activities and created a broad-based program that implemented far-reaching public interaction and outreach tactics. Over the last two decades, DOE informed, educated, and engaged a myriad of interested local, national, and international parties using various traditional and innovative approaches. The Yucca Mountain Project's intensive public affairs initiatives were instrumental in involving the public

    IntroductionEach year the National Aeronautics and Space Administration (NASA) sponsors a variety of public outreach events to share information with educators, students, and the general public. These events are designed to increase interest in and awareness of the mission and goals of NASA. Planning and implementation best practices gleaned from the NASA SMD Education's review of large-scale events, "Best Practices in Outreach Events" will be shared. Outcomes from an event, i C Ceres, celebrating the Dawn mission's arrival at dwarf planet Ceres that utilized these strategies will be shared. Best practices included can be pertinent for all event organizers and evaluators regardless of event size. BackgroundThe literature review focused on identifying evaluations of large-scale public outreach events—and, within these evaluations, identifying best practices. The following criteria for identifying journal articles and reports to potentially include: Public, science-related events open to adults and children. Events with more than 1,000 attendees. Events that occurred during the last 5 years. Evaluations that included information on data collected from visitors and/or volunteers. Evaluations that specified the type of data collected, methodology, and associated results. Planning and Implementation Best PracticesThe literature review revealed key considerations for planning and of large-scale events implementing events. A summary of related best practices is presented below. 1) Advertise the event 2) Use and advertise access to scientists 3) Recruit scientists using these findings 4) Ensure that the event is group and particularly child friendly 5) Target specific event outcomes Best Practices Informing Real-world Planning, Implementation and EvaluationDawn mission's collaborative design of a series of events, i C Ceres, including in-person, interactive events geared to families and live presentations will be shared.

    Many outreach events have been proposed by the scientific community to celebrate the Centenary of the January 13, 1915 earthquake, that devastated the Marsica territory, located in Central Apennines. The Laboratorio Divulgazione Scientifica e Attività Museali of the Istituto Nazionale di Geofisica e Vulcanologia (INGV's Laboratory for Outreach and Museum Activities) in Rome, has realised an interactive exhibition in the Castello Piccolomini, Celano (AQ), to retrace the many aspects of the earthquake disaster, in a region such as Abruzzo affected by several destructive earthquakes during its history. The initiatives represent an ideal opportunity for the development of new programs of communication and training on seismic risk and to spread the culture of prevention. The INGV is accredited with the Servizio Civile Nazionale (National Civic Service) and volunteers are involved in the project "Science and Outreach: a comprehensive approach to the divulgation of knowledge of Earth Sciences" starting in 2014. In this contest, volunteers had the opportunity to fully contribute to the exhibition, in particular, promoting and realising two panels concerning the social and environmental consequences of the Marsica earthquake. Describing the serious consequences of the earthquake, we may raise awareness about natural hazards and about the only effective action for earthquake defense: building with anti seismic criteria. After studies and researches conducted in libraries and via web, two themes have been developped: the serious problem of orphans and the difficult reconstruction. Heavy snowfalls and the presence of wolves coming from the high and wild surrounding mountains complicated the scenario and decelerated the rescue of the affected populations. It is important to underline that the earthquake was not the only devastating event in the country in 1915; another drammatic event was, in fact, the First World War. Whole families died and the still alive infants and

  7. Perspectives on fuel ethanol consumption and trade

    Since the year 2000 or so there has been a rapid growth on fuel ethanol production and consumption, particularly in US and Brazil. Ethanol trade represented about 10% of world consumption in 2005, Brazil being the main exporter. The most important consumer markets - US and European Union (EU) - have trade regimes that constrained the comparative advantages of the most efficient producers, such as Brazil. This paper evaluates the fuel ethanol market up to 2030 together with the potential for international biotrade. Based on forecasts of gasoline consumption and on targets and mandates of fuel ethanol use, it is estimated that demand could reach 272 Gl in 2030, displacing 10% of the estimated demand of gasoline (Scenario 1), or even 566 Gl in the same year, displacing about 20% of the gasoline demand (Scenario 2). The analysis considers fuel ethanol consumption and production in US, EU-25, Japan, China, Brazil and the rest of the world (ROW-BR). Without significant production of ethanol from cellulosic materials in this period, displacing 10% of the gasoline demand in 2030, at reasonable cost, can only be accomplished by fostering fuel ethanol production in developing countries and enhancing ethanol trade. If the US and EU-25 reach their full production potential (based on conventional routes), the minimum amount that could be traded in 2030 would be about 34 Gl. Displacing 20% of the gasoline demand by 2030 will require the combined development of second-generation technologies and large-scale international trade in ethanol fuel. Without second-generation technologies, Scenario 2 could become a reality only with large-scale production of ethanol from sugarcane in developing countries, e.g., Brazil and ROW-BR could be able to export at least 14.5 Gl in 2010, 73.9 Gl in 2020 and 71.8 Gl in 2030.

    The effects of autoshaping procedures (paired vs. random) and sipper fluid (ethanol vs. water) on sipper-directed drinking were evaluated in male Long-Evans rats maintained with free access to food and water. For the paired/ethanol group (n=16), autoshaping procedures consisted of presenting the ethanol sipper (containing 0% to 28% unsweetened ethanol) conditioned stimulus (CS) followed by the response-independent presentation of food unconditioned stimulus (US). The random/ethanol group (n=8) received the sipper CS and food US randomly with respect to one another. The paired/water group (n=8) received only water in the sipper CS. The paired/ethanol group showed higher grams per kilogram ethanol intake than the random/ethanol group did at ethanol concentrations of 8% to 28%. The paired/ethanol group showed higher sipper CS-directed milliliter fluid consumption than the paired/water group did at ethanol concentrations of 1% to 6%, and 15%, 16%, 18%, and 20%. Following a 42-day retention interval, the paired/ethanol group showed superior retention of CS-directed drinking of 18% ethanol, relative to the random/ethanol group, and superior retention of CS-directed milliliter fluid drinking relative to the paired/water group. When tested for home cage ethanol preference using limited access two-bottle (28% ethanol vs. water) procedures, the paired/ethanol and random/ethanol groups did not differ on any drinking measures.

    Effects of 3 ionophores and 2 antibiotics on in vitro H(2)S production, IVDMD, total gas production, and VFA profile with or without added S were examined. In Exp. 1, ruminal fluid from 2 ruminally cannulated steers fed a steam-flaked corn-based diet (75% concentrate) without ionophore and antibiotics for 28 d before collection was used to inoculate in vitro cultures. Treatments were control (no ionophore or antibiotic), 3 ionophores (lasalocid sodium and monensin sodium at 5 mg/L or laidlomycin propionate at 1.65 mg/L), and 2 antibiotics (chlortetracycline hydrochloride at 5 mg/L and tylosin tartarate at 1.25 mg/L). Cultures also had 0 or 1.75 mg of S/L (from sodium sulfate). No S x ionophore-antibiotic treatment interactions were noted (P > 0.53) for IVDMD, total gas production, and H(2)S production. Hydrogen sulfide (mumol/g of fermentable DM) was increased (P production tended (P = 0.09) to be increased with additional S; however, IVDMD was not affected by added S (P = 0.90). Production of H(2)S was not affected by ionophores or antibiotics (P > 0.18). On average, IVDMD (P = 0.05) was greater for ionophores than for antibiotics, whereas total gas production was less for ionophores than for control (P antibiotics (P 0.20) in acetate, propionate, or acetate:propionate between ionophores and control (S x treatment interaction, P = 0.03). In Exp. 2, the effects of ionophore-antibiotic combinations with added S were examined using the same procedures as in Exp. 1. Treatments were control, monensin plus tylosin (MT), and lasalocid plus chlortetracycline (LCTC), with concentrations of the ionophores and antibiotics as in Exp. 1. No differences were observed among treatments for H(2)S production (P > 0.55). Treatments MT and LCTC tended (P = 0.06) to increase IVDMD and decreased (P = 0.02) gas production vs. control. Proportion of acetate (P = 0.01) and acetate:propionate (P antibiotics we evaluated did not affect production of H(2)S gas in an in vitro rumen culture

    I report on current usage of multimedia and social networking 'Web 2.0' tools for Education and Outreach in high-energy physics, and discuss their potential for internal communication within large worldwide collaborations, such as those of the LHC. Following a brief description of the history of Web 2.0 development, I present a survey of the most popular sites and describe their usage in HEP to disseminate information to students and the general public. I then discuss the potential of certain specific tools, such as document and multimedia sharing sites, for boosting the speed and effectiveness of information exchange within the collaborations. I conclude with a brief discussion of the successes and failures of these tools, and make suggestions for improved usage in the future.

    In the next two years, during the NASA Year of the Solar System, spacecraft from NASA and our international partners will; encounter a comet, orbit asteroid 4 Vesta, continue to explore Mars with rovers, and launch robotic explorers to the Moon and Mars. We have pieces of all these worlds in our laboratories, and their continued study provides incredibly valuable "ground truth" to complement space exploration missions. Extensive information about these unique materials, as well as actual lunar samples and meteorites, are available for display and education. The Johnson Space Center (JSC) has the unique responsibility to curate NASA's extraterrestrial samples from past and future missions. Curation includes documentation, preservation, preparation, and distribution of samples for research, education, and public outreach.

    We evaluated the first workplace intervention to help smokers quit in Hong Kong. Smoking employees (N = 642) received a 26-page self-help booklet and 15 fix SMS within 3 months and chose to receive cognitive behavioral workshop (N = 76), or face-to-face counseling (N = 11), or group health talk (N = 516), or telephone counseling (N = 39). Twenty participants were interviewed individually for their opinions about the interventions. By intention-to-treat, the overall self-reported past 7-day point prevalence quit rate was 31.0% and 32.9%, and reduction rate was 15.0% and 13.2% at 6 and 12-months, respectively. More than 20% of the unmotivated smokers at baseline (N = 399) quit in this program. Proactive outreach workplace smoking cessation programs with diverse intensity but without medications, chosen by smokers and supported by employers without further incentives, were feasible in busy working environment in Hong Kong.

  14. In-house training, formal education and public outreach

    1992-01-01

    This paper assumes that a stronger national commitment to public education on nuclear energy and, most particularly radioactive waste management, it needed to overcome public resistance to nuclear projects. Effective public education must become the superordinate goal uniting industry, government, professional societies, national laboratories and the educational community. Since instruction is labor intensive, we must search for more cost effective ways of achieving results. Therefore, this paper proposes: Collaborative training and educational strategies involving as many of the stakeholders as possible; and Innovative tools to improve the credibility, quality and cost effectiveness of education. This win-win approach can reduce the collective expenditures through cost-sharing, as well as the sharing of resources and products. It can close gaps in both in-house training and formal education. Finally, in public outreach, the joint approach addresses the politics of sponsorship by providing checks and balances, and thus improving credibility and public acceptance

    Two recent outreach projects are making use of public communities to enhance and build upon the first phases setup by physicists. “HiggsHunters” asked the public to search for displaced vertices in event displays, during which time a pool of trusted members arose in the associated discussion. The data this generated is now being analysed by schoolchildren, through which they can both learn the principles of scientific research and contribute directly to it. Also involving schoolchildren is “ATLAScraft”, a recreation of ATLAS and the wider CERN complex in minecraft. Here, the basic layout was provided, but students subsequently researched and created their own mini-games to explain various aspects of the LHC and detector physics to others.

    1987-01-01

    To provide direct outreach to local governments, the Transportation Management Division of the United States Department of Energy asked the Urban Consortium and its Energy Task Force to assemble representatives for two workshops focusing on the transport of nuclear materials. The first session, for jurisdictions east of the Mississippi River, was held in New Orleans on May 5--6, 1988; the second was conducted on June 6--7, 1988 in Denver for jurisdictions to the west. Twenty local government professionals with management or operational responsibility for hazardous materials transportation within their jurisdictions were selected to attend each workshop. The discussions identified five major areas of concern to local government professionals; coordination; training; information resources; marking and placarding; and responder resources. Integrated federal, state, and local levels of government emerged as a priority coordination issue along with the need for expanded availability of training and training resources for first-reponders

    Scientists and engineers sometimes think that to do outreach and education activities well, they have to be exceptional at public speaking, writing, or interacting with children or laypeople. However, during my career in planetary science, I've been involved in and close to a myriad of ways of getting involved in E/PO and found that there is a path to involvement for every personality. Another common misconception is that doing E/PO will hurt one's career as a scientist or engineer. While many of us do not have a great deal of time to spend on E/PO, there are efficient ways of making an impact. This talk will discuss ways that I've found work for me and for colleagues and tips on finding your own niche in these activities.

    With the development of the International Space Station and the need for international collaboration for returning to the moon and developing a mission to Mars, NASA has embarked on developing international educational programs related to space exploration. In addition, with the explosion of educational technology, linking students on a global basis is more easily accomplished. This technology is bringing national and international issues into the classroom, including global environmental issues, the global marketplace, and global collaboration in space. We present the successes and lessons learned concerning international educational and public outreach programs that we have been involved in for NASA as well as the importance of sustaining these international peer collaborative programs for the future generations. These programs will undoubtedly be critical in enhancing the classroom environment and will affect the achievements in and attitudes towards science, technology, engineering and mathematics.

    I present the results of two NASA-IDEAS/STScI sponsored astronomy outreach programs for seriously ill children and their families staying at the Ronald McDonald House of Long Island (New Hyde Park, NY) and for children hospitalized at the Children's Medical Center, Winthrop University Hospital (Mineola, NY). These programs are designed for children of all ages and include STSCi's Tonight's Sky (monthly guide to the sky); telescope observations of the Moon, Sun, planets, nebulae, and stars; and hands-on activities. During cloudy weather remote/robotic telescope observations are shown. Edible demonstrations using chocolate, marshmallows, and popcorn are used to stimulate interest. The staff at the Ronald McDonald House and Children's Medical Center are being trained to use the telescope and to do demonstrations. These educational activities help children and their families learn about astronomy while providing a diversion to take their minds off their illness during a stressful time.

    The SPIE/OSA Student Chapter at Michigan Technological University have developed demonstrations and workshops for science and engineering outreach. The practical approach to holography promotes the study of photonic related sciences in high school and college-aged students. An introduction to laser safety, optical laboratory practices, and basic laser coherence theory is given in order to first introduce the participants to the science behind the holograms. The students are then able to create a hologram of an item of their choice, personalizing the experience. By engaging directly, the students are able to see how the theory is applied and also enforces a higher level of attention from them so no mistakes are made in their hologram. Throughout the course participants gain an appreciation for photonics by learning how holograms operate and are constructed through hands on creation of their own holograms. This paper reviews the procedures and methods used in the demonstrations and workshop while examining the overall student experience.

    The DOE's National Nuclear Security Agency (NNSA) asked Pacific Northwest National Laboratory (PNNL) to consider the role of individual scientists in upholding safety and security. The views of scientists were identified as being a critical component of this policy process. Therefore, scientists, managers, and representatives of Institutional Biosafety Committees (IBCs) at the national labs were invited to participate in a brief survey and a set of focus groups. In addition, three focus groups were conducted with scientists, managers, and IBC representatives to discuss some of the questions related to education, outreach, and codes of conduct in further detail and gather additional input on biosecurity and dual-use awareness at the laboratories. The overall purpose of this process was to identify concerns related to these topics and to gather suggestions for creating an environment where both the scientific enterprise and national security are enhanced.

    An outreach project which juxtaposed technology (Grateful Med) and a human intermediary (a circuit librarian) to serve health professionals in a rural area of Illinois is described. The five goals of the project were: promote Grateful Med as a clinical tool; introduce circuit librarianship to Illinois; heighten the awareness of health professionals to the value of timely information services; increase the visibility of the resource library; and evaluate the impact of the two components, Grateful Med and circuit librarianship. While the project was well-received and enjoyed short-term success, sustaining the same level of information activity post-project has not been achieved. Insuring utilization of health information by remote health professionals may be characterized as a Sisyphean task.

    Due to its fascinating structures, the Gran Sasso National Laboratory (LNGS) offers huge opportunities for communication and outreach activities conceived for students and general public. A great effort is devoted to the organisation of the "OPEN DAY", in which the scientific staff of Gran Sasso introduces non expert people to the main relevant research topics of the laboratory through interactive demonstrations and particle detectors. In particular, a portable cosmic rays telescope has been realized: the detector is used by LNGS team in pubblic events as well as to promote the scientific activities of the Laboratory. In order to point out the importance of the scientific culture for young people, LNGS is involved in the organisation of several training courses for students and teachers focused on the improvement of the knowledge on modern physics topics. Since May 2008 is operating in Teramo the "Galileium", an interactive museum for physics and astrophysics.

    At EPFL, a strategy for organising scientific outreach activities has been developed and a programme comprising various measures and actions elaborated to promote science and technology among youngsters, especially young girls. As part of this programme, workshops and chemistry camps are developed and carried out for children and youngsters aged from 7 to 16 years old. These workshops are adapted to the age of the participants and allow them to discover chemistry in a fascinating way and become familiar with this field, understand how useful it is to society and learn about the professions it opens up. Some of the workshops take place at EPFL and others are organised in schools in the French-speaking cantons of Switzerland during the touring campaign of a bus named 'Les sciences, ça m'intéresse !'

    The American Physical Therapy Association (APTA) has been working toward a vision of increasing professional focus on societal-level health. However, performance of social responsibility and related behaviors by physical therapists remain relatively poorly integrated into practice. Promoting a focus on societal outreach is necessary for all health care professionals to impact the health of their communities. The objective was to document the validity of the 14-item Societal Outreach Scale (SOS) for use with practicing physical therapists. This study used a cross-sectional survey. The SOS was transmitted via email to all therapists who were licensed and practicing in 10 states in the United States that were purposefully selected to assure a broad representation. A sample of 2612 usable responses was received. Factor analysis was applied to assess construct validity of the instrument. Of alternate models, a 3-factor model best demonstrated goodness of fit with the sample data according to conventional indices (standardized root mean squared residual = .03, comparative fit index .96, root mean square error of approximation = .06). The 3 factors measured by the SOS were labeled Societal-Level Health Advocacy, Community Engagement/Social Integration, and Political Engagement. Internal consistency reliability was 0.7 for all factors. The 3-factor SOS demonstrated acceptable validity and reliability. Though the sample included a broad representation of physical therapists, this was a single cross-sectional study. Additional confirmatory factor analysis, reliability testing, and word refinement of the tool are warranted. Given the construct validity and reliability of the 3-factor SOS, it is recommended for use as a validated instrument to measure physical therapists' performance of social responsibility and related behaviors.

    Since 2004, the Gemini Observatory’s week-long Journey Through the Universe (JTtU) program has successfully shared the excitement of scientific research with teachers, students and the public on Hawaii’s Big Island. Based on the national JTtU program started in 1999, the Hawai‘i version reaches an average of 7,000 students annually and each year features a different theme shared with a diverse set of learners. In 2010, the theme includes the integration of the GalileoScope-produced as a keystone project for the International Year of Astronomy. In preparation, a pilot teacher workshop (held in October 2009) introduced local island teachers to the GalileoScope and a 128-page educator’s activity resource book coordinated by the University of Wyoming. Response from this initial teacher’s workshop has been strong and evaluations plus follow-up actions by participating teachers illustrate that the integration of the GalileoScope has been successful based upon this diverse sample. Integrating GalileoScopes into Chilean schools in 2010 is also underway at Gemini South. This program will solicit informal proposals from educators who wish to use the telescopes in classrooms and a Spanish version of the teacher resource book is planned. The authors conclude that integration of the GalileoScope into an existing outreach program is an effective way to keep content fresh, relevant and engaging for both educators and students. This initiative is funded by Gemini Observatory outreach program. The Gemini Observatory is operated by the Association of Universities for Research in Astronomy, Inc., under a cooperative agreement with the NSF on behalf of the Gemini partnership: the National Science Foundation (US), the Science and Technology Facilities Council (UK), the National Research Council (Canada), CONICYT (Chile), the Australian Research Council (Australia), Ministério da Ciência e Tecnologia (Brazil), and Ministerio de Ciencia, Tecnología e Innovación Productiva

  8. Information needs related to extension service and community outreach.

    Air quality affects everyone. Some people are affected by air quality impacts, regulations, and technological developments in several ways. Stakeholders include the medical community, ecologists, government regulators, industries, technology providers, academic professionals, concerned citizens, the news media, and elected officials. Each of these groups may perceive problems and opportunities differently, but all need access to information as it is developed. The diversity and complexity of air quality problems contribute to the challenges faced by extension and outreach professionals who must communicate with stakeholders having diverse backgrounds. Gases, particulates, biological aerosols, pathogens, and odors all require expensive and relatively complex technology to measure and control. Economic constraints affect the ability of regulators and others to measure air quality, and industry and others to control it. To address these challenges, while communicating air quality research results and concepts to stakeholders, three areas of information needs are evident. (1) A basic understanding of the fundamental concepts regarding air pollutants and their measurement and control is needed by all stakeholders; the Extension Specialist, to be effective, must help people move some distance up the learning curve. (2) Each problem or set of problems must be reasonably well defined since comprehensive solution of all problems simultaneously may not be feasible; for instance, the solution of an odor problem associated with animal production may not address atmospheric effects due to ammonia emissions. (3) The integrity of the communication process must be preserved by avoiding prejudice and protectionism; although stakeholders may seek to modify information to enhance their interests, extension and outreach professionals must be willing to present unwelcome information or admit to a lack of information. A solid grounding in fundamental concepts, careful and fair problem

    The Solar TErrestrial RElations Observatory (STEREO) is scheduled for launch in Spring 2006. STEREO will study the Sun with two spacecrafts in orbit around it and on either side of Earth. The primary science goal is to understand the nature and consequences of Coronal Mass Ejections (CMEs). Despite their importance, scientists don't fully understand the origin and evolution of CMEs, nor their structure or extent in interplanetary space. STEREO's unique 3-D images of the structure of CMEs will enable scientists to determine their fundamental nature and origin. We will discuss the Education and Public Outreach (E/PO) program for the In-situ Measurement of Particles And CME Transients (IMPACT) suite of instruments aboard the two crafts and give examples of upcoming activities, including NASA's Sun-Earth day events, which are scheduled to coincide with a total solar eclipse in March. This event offers a good opportunity to engage the public in STEREO science, because an eclipse allows one to see the solar corona from where CMEs erupt. STEREO's connection to space weather lends itself to close partnerships with the Sun-Earth Connection Education Forum (SECEF), The Exploratorium, and UC Berkeley's Center for New Music and Audio Technologies to develop informal science programs for science centers, museum visitors, and the public in general. We will also discuss our teacher workshops locally in California and also at annual conferences such as those of the National Science Teachers Association. Such workshops often focus on magnetism and its connection to CMEs and Earth's magnetic field, leading to the questions STEREO scientists hope to answer. The importance of partnerships and coordination in working in an instrument E/PO program that is part of a bigger NASA mission with many instrument suites and many PIs will be emphasized. The Education and Outreach Porgram is funded by NASA's SMD.

    The Mead Westvaco Observatory (MWVO), located in Columbus State University's Coca-Cola Space Science Center, is dedicated to education and research in astronomy through hands-on engagement and public participation. The MWVO has recently received funding to upgrade from a 16-inch Meade LX-200 telescope to a PlaneWave CDK 24-inch Corrected Dall-Kirkham Astrograph telescope. This and other technological upgrades will allow this observatory to stream live webcasts for astronomical events, allowing a worldwide public audience to become a part of the growing astronomical community. This poster will explain the upgrades that are currently in progress as well as the results from the current calibrations. The goal of these upgrades is to provide facilities capable of both research-class projects and widespread use in education and public outreach. We will present our initial calibration and tests of the observatory equipment, as well as its use in webcasts of astronomical events, in solar observing through the use of specialized piggy-backed telescopes, and in research into such topics as asteroids, planetary and nebula imaging. We will describe a pilot research project on asteroid orbit refinement and light curves, to be carried out by Columbus State University students. We will also outline many of the K-12 educational and public outreach activities we have designed for these facilities. Support and funding for the acquisition and installation of the new PlaneWave CDK 24 has been provided by the International Museum and Library Services via the Museums for America Award.

    Although the purchase price of cellulosic feedstocks is competitive with petroleum on an energy basis, the cost of lignocellulose conversion to ethanol using today’s technology is high. Cost reductions can be pursued via either in-paradigm or new-paradigm innovation. As an example of new-paradigm innovation, consolidated bioprocessing using thermophilic bacteria combined with milling during fermentation (cotreatment) is analyzed. Acknowledging the nascent state of this approach, our analysis indicates potential for radically improved cost competitiveness and feasibility at smaller scale compared to current technology, arising from (a) R&D-driven advances (consolidated bioprocessing with cotreatment in lieu of thermochemical pretreatment and added fungal cellulase), and (b) configurational changes (fuel pellet coproduction instead of electricity, gas boiler(s) in lieu of a solid fuel boiler).

    Studies in animal models have shown that repeated episodes of alcohol dependence and withdrawal promote escalation of drinking that is presumably associated with alterations in the addiction neurocircuitry. Using a lithium chloride-ethanol pairing procedure to devalue the reinforcing properties of ethanol, the present study determined whether multiple cycles of chronic intermittent ethanol (CIE) exposure by vapor inhalation also alters the sensitivity of drinking behavior to the devaluation of ethanol's reinforcing effects. The effect of devaluation on operant ethanol self-administration and extinction was examined in mice prior to initiation of CIE (short drinking history) and after repeated cycles of CIE or air control exposure (long drinking history). Devaluation significantly attenuated the recovery of baseline ethanol self-administration when tested either prior to CIE or in the air-exposed controls that had experienced repeated bouts of drinking but no CIE. In contrast, in mice that had undergone repeated cycles of CIE exposure that promoted escalation of ethanol drinking, self-administration was completely resistant to the effect of devaluation. Devaluation had no effect on the time course of extinction training in either pre-CIE or post-CIE mice. Taken together, these results are consistent with the suggestion that repeated cycles of ethanol dependence and withdrawal produce escalation of ethanol self-administration that is associated with a change in sensitivity to devaluation of the reinforcing properties of ethanol.

    Enzymatic hydrolysis of steam pretreated sallow gives highest yields of soluble sugars when hemicellulose is degraded already in the pretreatment step. The steam pretreatment equipment is rebuilt so that 75 g (dry matter) material instead of 7 g can be treated each time. The cellulose production has been increased 123% by the utilization of aqueous two-phase systems as compared to regular growth medium. The cellulase activity per gram of cellulose has been increased from 42 FPU in regular growth medium to 156 FPU in aqueous two-phase systems. Crude dextran can be used for enzyme production. Enzyme recovery up to 75% has been achieved by combining aqueous two-phase technique with membrane technique. Using the enzyme glucose isomerase in combination with S. cerevisiae theoretical yields in pentose fermentations have been achieved, with a product concentration of 60 g/L and a productivity of 2 g/L x h. Yeast and enzyme can be recirculated using membrane technique. Computer simulation shows that the rate equation for enzymatic hydrolysis with respect to inhibiting sugar concentrations can be used to interpolate with respect to sugar concentrations. Computer simulations show that hydrolysis experiments should focus on high substrate concentrations (>10%) using fed-batch technique and enzyme concentrations in the range of 2-8% in relation to substrate dry matter. The combined 'flow injection analysis', FIA, and enzyme reactor probe has been adapted to enzymatic saccarifications of sodium hydroxide pretreated sallow. The gas membrane sensor for ethanol has been utilized in simultaneous saccharification and fermentation of sodium hydroxide pretreated sallow. A literature study concerning pervaporation for ethanol up-grading has been made.(Author).

    Ethanol is the most used biofuel in the world. It is part of the European biofuel strategy, which is intended to preserve finite fossil resources, reduce greenhouse gas emissions and strengthen European agriculture. In addition to its traditional use in E5 fuel, ethanol most recently features in new fuels for petrol engines in Europe: as E10 as an expansion of the already existing concept of ethanol blends, such as in E5, or as ethanol fuel E85, a blend made up primarily of ethanol. There is already extensive international experience for both types of fuel for example in the USA or Brazil. The use of ethanol as a biofuel is linked to sustainability criteria in Europe which must be proven through a certification scheme. In addition to ethanol, the integrated production process also provides vegetable protein which is used in food as well as in animal feed and therefore provides the quality products of processed plants used for sustainable energy and in animal and human food. Ethanol has an effect on the vapour pressure, boiling behaviour and octane number of the fuel blend. Adjusting the blend stock petrol to fulfil the quality requirements of the final fuel is therefore necessary. Increasing the antiknock properties, increasing the heat of evaporation of the fuel using ethanol and the positive effects this has on the combustion efficiency of the petrol engine are particularly important. Investigations on cars or engines that were specifically designed for fuel with a higher ethanol content show significant improvements in using the energy from the fuel and the potential to reduce carbon dioxide emissions if fuels containing ethanol are used. The perspective based purely on an energy equivalent replacement of fossil fuels with ethanol is therefore misleading. Ethanol can also contribute to increasing the energy efficiency of petrol engines as well as being a replacement source of energy. (orig.)

  15. Lithium-mediated protection against ethanol neurotoxicity

    Full Text Available Lithium has long been used as a mood stabilizer in the treatment of manic-depressive (bipolar disorder. Recent studies suggest that lithium has neuroprotective properties and may be useful in the treatment of acute brain injuries such as ischemia and chronic neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease and amyotrophic lateral sclerosis. One of the most important neuroprotective properties of lithium is its anti-apoptotic action. Ethanol is a neuroteratogen and fetal alcohol spectrum disorders (FASD are caused by maternal ethanol exposure during pregnancy. FASD is the leading cause of mental retardation. Ethanol exposure causes neuroapoptosis in the developing brain. Ethanol-induced loss of neurons in the central nervous system underlies many of the behavioral deficits observed in FASD. Excessive alcohol consumption is also associated with Wernicke–Korsakoff syndrome and neurodegeneration in the adult brain. Recent in vivo and in vitro studies indicate that lithium is able to ameliorate ethanol-induced neuroapoptosis. Lithium is an inhibitor of glycogen synthase kinase 3 (GSK3 which has recently been identified as a mediator of ethanol neurotoxicity. Lithium’s neuroprotection may be mediated by its inhibition of GSK3. In addition, lithium also affects many other signaling proteins and pathways that regulate neuronal survival and differentiation. This review discusses the recent evidence of lithium-mediated protection against ethanol neurotoxicity and potential underlying mechanisms.

    Lithium is widely used for the treatment of bipolar disorder. Recent studies have demonstrated its neuroprotective effect. Ethanol is a potent neurotoxin that is particularly harmful to the developing nervous system. In this study, we evaluated lithium's neuroprotection against ethanol-induced apoptosis. Transient exposure of infant mice to ethanol caused apoptotic cell death in brain, which was prevented significantly by administering a low dose of lithium 15 min later. In cultured cerebellar granule neurons, ethanol-induced apoptosis and activation of caspase-3/9, both of which were prevented by lithium. However, lithium's protection is not mediated by its commonly known inhibition of glycogen synthase3β, because neither ethanol nor lithium has significant effects on the phosphorylation of Akt (ser473) or GSK3β (ser9). In addition, the selective GSK-3β inhibitor SB-415286 was unable to prevent ethanol-induced apoptosis. These data suggest lithium may be used as a potential preventive measure for ethanol-induced neurological deficits

    The NASA Science Education and Public Outreach Forums support the NASA Science Mission Directorate (SMD) and its education and public outreach community in enhancing the coherence, efficiency, and effectiveness of SMD-funded education and public outreach programs. As part of this effort, the four Forums (Astrophysics, Earth Science, Heliophysics, and Planetary Science) work together to coordinate resources and opportunities that enable sharing of best practices relevant to SMD-funded education and public outreach. Efforts include collaborating with SMD-funded education and public outreach programs to identify community needs for professional development; raising awareness of the existing body of best practices and educational research; and, organizing distance learning and face-to-face professional development opportunities. Topics include best practices in navigating NASA SMD education and public outreach program requirements, social media, engaging girls in science, and student misconceptions / reasoning difficulties. Opportunities to share best practices and learn from experts are extended to the broader astronomy and astrophysics community through the annual Astronomical Society of the Pacific education and public outreach conference. Evaluation of community professional development resources and opportunities is in progress.

    Full Text Available While genetics impacts the type and severity of damage following developmental ethanol exposure, little is currently known about the molecular pathways that mediate these effects. Traditionally, research in this area has used a candidate gene approach and evaluated effects on a gene-by-gene basis. Recent studies, however, have begun to use unbiased approaches and genetic reference populations to evaluate the roles of genotype and epigenetic modifications in phenotypic changes following developmental ethanol exposure, similar to studies that evaluated numerous alcohol-related phenotypes in adults. Here, we present work assessing the role of genetics and chromatin-based alterations in mediating ethanol-induced apoptosis in the developing nervous system. Utilizing the expanded family of BXD recombinant inbred mice, animals were exposed to ethanol at postnatal day 7 via subcutaneous injection (5.0 g/kg in 2 doses. Tissue was collected 7 hours after the initial ethanol treatment and analyzed by activated caspase-3 immunostaining to visualize dying cells in the cerebral cortex and hippocampus. In parallel, the levels of two histone modifications relevant to apoptosis, γH2AX and H3K14 acetylation, were examined in the cerebral cortex using protein blot analysis. Activated caspase-3 staining identified marked differences in cell death across brain regions between different mouse strains. Genetic analysis of ethanol susceptibility in the hippocampus led to the identification of a quantitative trait locus on chromosome 12, which mediates, at least in part, strain-specific differential vulnerability to ethanol-induced apoptosis. Furthermore, analysis of chromatin modifications in the cerebral cortex revealed a global increase in γH2AX levels following ethanol exposure, but did not show any change in H3K14 acetylation levels. Together, these findings provide new insights into the molecular mechanisms and genetic contributions underlying ethanol

    Two respiratory-deficient nuclear petites, FY23{Delta}pet191 and FY23{Delta}cox5a, of the yeast Saccharomyces cerevisiae were generated using polymerase-chain-reaction-mediated gene disruption, and their respective ethanol tolerance and productivity assessed and compared to those of the parental grande, FY23WT, and a mitochondrial petite, FY23{rho}{sup 0}. Batch culture studies demonstrated that the parental strain was the most tolerant to exogenously added ethanol with an inhibition constant. K{sub i}, of 2.3% (w/v) and a specific rate of ethanol production, q{sub p}, of 0.90 g ethanol g dry cells{sup -1} h{sup -1}. FY23{rho}{sup 0} was the most sensitive to ethanol, exhibiting a K{sub i} of 1.71% (w/v) and q{sub p} of 0.87 g ethanol g dry cells{sup -1} h{sup -1}. Analyses of the ethanol tolerance of the nuclear petites demonstrate that functional mitochondria are essential for maintaining tolerance to the toxin with the 100% respiratory-deficient nuclear petite, FY23{Delta}pet191, having a K{sub i} of 2.14% (w/v) and the 85% respiratory-deficient FY23{Delta}cox5a, having a K{sub i} of 1.94% (w/v). The retention of ethanol tolerance in the nuclear petites as compared to that of FY23{rho}{sup 0} is mirrored by the ethanol productivities of these nuclear mutants, being respectively 43% and 30% higher than that of the respiratory-sufficient parent strain. This demonstrates that, because of their respiratory deficiency, the nuclear petites are not subject of the Pasteur effect and so exhibit higher rates of fermentation. (orig.)

    The purpose of this study was to evaluate the role of ethanol in deaths due to heroin intoxication. Over a 12 month period, all cases investigated by the Office of the Chief Medical Examiner, State of Maryland where a blood screen by Roche Abuscreen radioimmunoassay (RIA) was positive at a cutoff of 100 ng/mL were included in the study. Free morphine was quantitated using the Coat-A-Count RIA and ethanol was quantitated by head space gas chromatography. All presumptive morphine positive cases were confirmed by gas chromatography/mass spectrometry. Seventy of the 119 cases where death was attributed to narcotic or alcohol and narcotic intoxication had blood ethanol concentrations (BAC) greater than or equal to 0.02 g/dL; 48 had BAC > or = 0.10 g/dL. Only 3 of 45 cases where morphine was identified but was unrelated to death had BAC > or = 0.02 g/dL. At all ranges of free morphine concentrations, there was a greater percentage of narcotic deaths when ethanol was present. From the data, we conclude that 1) the use of even small amounts of ethanol with heroin is clearly a risk factor in deaths due to heroin, 2) there are some heroin deaths where no free morphine is identified in the blood. In these deaths, ethanol is unlikely to be present, 3) at blood ethanol concentrations between 0.20 and 0.29 g/dL, the morphine concentrations in heroin deaths increased significantly, 4) at blood ethanol concentrations greater than 0.30 g/dL, morphine became less of a factor than the ethanol in causing death.

  1. Greenprint on ethanol production in Saskatchewan

    International Nuclear Information System (INIS)

    2002-04-01

    Investment in Saskatchewan's ethanol industry is being actively promoted by the provincial government. This document represents the provincial strategy in support of the ethanol industry, which will result in significant environmental benefits for the province and the residents through the increased use of ethanol as an additive to conventional gasoline. The big advantage offered by ethanol is a more complete fuel combustion, thereby reducing emissions of greenhouse gases by as much as 30 per cent. The production costs of ethanol have decreased in the last twenty years by 50 per cent. The competitiveness of ethanol should increase due to ongoing research and development progress being made. The agricultural sector should benefit through the creation of meaningful jobs in the sector, as well as offering new marketing opportunities to the grain producers of the province and the wood-product companies. A renewable resource, ethanol reduces carbon dioxide exhaust emissions bu up to 20 per cent, reduces the smog-creating compounds up to 15 per cent, and achieves a net reduction of up to 10 per cent in carbon dioxide emissions. The abundance of raw materials and resources required for the production of ethanol, Saskatchewan possesses an obvious advantage for becoming a world leader in the field. The government of Saskatchewan has developed its strategy, outlined in this document. It calls for tax incentives, the mandating of ethanol blend, opening up markets, working with communities. The industry size, economic impact, export potential, and future opportunities were briefly discussed in the last section of the document. 1 tab., 3 figs

    Full Text Available Abstract Background Despite having high smoking rates, there have been few tailored cessation programmes for male Bangladeshi and Pakistani smokers in the UK. We report on a qualitative evaluation of a community-based, outreach worker delivered, intervention that aimed to increase uptake of NHS smoking cessation services and tailor services to meet the needs of Bangladeshi and Pakistani men. Methods This was a longitudinal, qualitative study, nested within a phase II cluster randomised controlled trial of a complex intervention. We explored the perspectives and experiences of five outreach workers, two stop smoking service managers and a specialist stop smoking advisor. Data were collected through focus group discussions, weekly diaries, observations of management meetings, shadowing of outreach workers, and one-to-one interviews with outreach workers and their managers. Analysis was undertaken using a modified Framework approach. Results Outreach workers promoted cessation services by word of mouth on the streets, in health service premises, in local businesses and at a wide range of community events. They emphasised the reasons for cessation, especially health effects, financial implications, and the impact of smoking on the family. Many smokers agreed to be referred to cessation services, but few attended, this in part being explained by concerns about the relative inflexibility of existing service provision. Although outreach workers successfully expanded service reach, they faced the challenges of perceived lack of awareness of the health risks associated with smoking in older smokers and apathy in younger smokers. These were compounded by perceptions of "lip service" being given to their role by community organisations and tensions both amongst the outreach workers and with the wider management team. Conclusions Outreach workers expanded reach of the service through taking it to diverse locations of relevance to Pakistani and Bangladeshi

    The vapour phase catalytic dehydration of ethanol over Fe impregnated cadmium oxide was investigated between 200-450 0 C in atmospheric pressure. Electron transfer mechanisms involved in adsorption and catalytic dehydration reaction were investigated. The change in electrical conductivity of the catalyst resulting from calcination, adsorption and surface reaction processes were studied. Adsorption conductivity at low temperature ( 0 C) indicates that ethanol adsorbs as an electron donor. A mechanism of creation of interstitial Cd atoms responsible for the catalytic dehydration of ethanol on the catalyst surface was suggested. (orig.) [de

    Clinical laboratory outreach business is changing as more physician practices adopt an electronic medical record (EMR). Physician connectivity with the laboratory information system (LIS) is consequently becoming more important. However, there are no reports available to assist the informatician with establishing and maintaining outreach LIS-EMR connectivity. A four-stage scheme is presented that was successfully employed to establish unidirectional and bidirectional interfaces with multiple physician EMRs. This approach involves planning (step 1), followed by interface building (step 2) with subsequent testing (step 3), and finally ongoing maintenance (step 4). The role of organized project management, software as a service (SAAS), and alternate solutions for outreach connectivity are discussed.

    Highlights: ► Experimental density data are reported for (ethanol + decane) and (ethanol + decane + CO 2 ) mixtures. ► Compressed liquid densities were measured in a vibrating tube densimeter from (313 to 363) K. ► Excess molar volumes for (ethanol + decane) mixtures are positive. ► The presence of carbon dioxide in the (ethanol + decane) mixture causes negative excess molar volumes. - Abstract: Volumetric properties for the binary (ethanol + decane) and ternary (ethanol + decane + carbon dioxide) systems are reported from (313 to 363) K and pressures up to 20 MPa. Compressed liquid densities of both systems were measured in a vibrating tube densimeter at different compositions. Binary mixtures {x 1 ethanol + (1-x 1 ) decane} were prepared at x 1 = 0.0937, 0.1011, 0.2507, 0.4963, 0.7526, 0.9014. Compositions for the ternary system were prepared by varying the ethanol/decane relation and trying to keep constant the presence of carbon dioxide at about 0.2 mole fraction. These were {x 1 ethanol + x 2 decane + (1-x 1 -x 2 ) carbon dioxide} x 1 = 0.0657, 0.1986, 0.4087, 0.6042, 0.7109. Density results were correlated using an empirical model with five parameters. Deviations between experimental and calculated values agree and are within the experimental uncertainty. Isobaric expansivity, isothermal compressibility, thermal pressure coefficient, and internal pressure have been calculated for both binary and ternary systems using the empirical model.

    Acute consumption of ethanol results in reversible changes in learning and memory whereas chronic ethanol consumption of six or more months produces permanent deficits and neural damage in rodents. The goal of the current paper was determine whether shorter durations of chronic ethanol ingestion in mice would produce long-term deficits in learning and memory after the cessation of ethanol. We first examined the effects of four and eight weeks of 20% ethanol followed by a three week withdrawal period on learning and memory in mice. We determined that three weeks after eight, but not four, weeks of 20% ethanol consumption resulted in deficits in learning and long-term memory (seven days) in T-maze footshock avoidance and Greek Cross brightness discrimination, step-down passive avoidance and shuttlebox active avoidance. Short-term memory (1 hr) was not affected. The deficit was not related to changes in thiamine status, caloric intake, or nonmnemonic factors, such as, activity or footshock sensitivity. Lastly, we examined if the mice recovered after longer durations of withdrawal. After eight weeks of ethanol, we compared mice after three and 12 weeks of withdrawal. Mice that had been off ethanol for both three and 12 weeks were impaired in T-maze footshock avoidance compared to the controls. The current results indicate that a duration of ethanol consumption as short as eight weeks produces deficits in learning and memory that are present 12 weeks after withdrawal.

    This research thesis addresses the study of the behaviour of binary mixtures submitted to ionizing radiations, and notably aims, by studying the case of water-ethanol mixtures, at verifying solutions proposed by previously published works on the origin of hydrogen atoms and of molecular hydrogen, on the intervention of excited atoms, and on the origin of products appearing under radiolysis. The experimental part of this work consists in the dosing of products formed in water-ethanol mixtures irradiated in presence or absence of nitrate, hydrogen, hydrocarbon, acetaldehyde, 2-3 butanediol and nitrite. Results are discussed and interpreted in terms of acetaldehyde efficiency, 2-3 butanediol efficiencies, and hydrocarbon efficiencies in pure ethanol, and in water-ethanol mixtures. The influence of the presence of nitrate ions in mixtures is also discussed

    Ethanol is present in the transpiration stream of flooded and unflooded trees in concentrations up to 0.5mM. Transpired ethanol does not evaporate but is remetabolized by foliage and upper stems in Populus deltoides. 14 C-ethanol was supplied in the transpiration stream to excised leaves and shoots; more than 98% was incorporated. Less than 1% was respired as CO 2 . Organic and amino acids were labelled initially, with eventual accumulations in water- and chloroform-soluble fractions and into protein. Much of the label was incorporated into stem tissue, with little reaching the lamina. These experiments suggest that ethanol is not lost transpirationally through the leaves, but is efficiently recycled in a manner resembling lactate recycling in mammals

    We tested the hypothesis that the irreversible gamma-amino butyric acid (GABA) transaminase inhibitor, γ-vinyl GABA (Vigabatrin; VGB) would reduce ethanol reinforcement and enhance the discriminative stimulus effect of ethanol, effectively reducing ethanol intake. The present studies used adult C57BL/6J (B6) mice in well-established operant, two-bottle choice consumption, locomotor activity and ethanol discrimination procedures, to examine comprehensively the effects of VGB on ethanol-supported behaviors. VGB dose-dependently reduced operant responding for ethanol as well as ethanol consumption for long periods of time. Importantly, a low dose (200 mg/kg) of VGB was selective for reducing ethanol responding without altering intake of food or water reinforcement. Higher VGB doses (>200 mg/kg) still reduced ethanol intake, but also significantly increased water consumption and, more modestly, increased food consumption. While not affecting locomotor activity on its own, VGB interacted with ethanol to reduce the stimulatory effects of ethanol on locomotion. Finally, VGB (200 mg/kg) significantly enhanced the discriminative stimulus effects of ethanol as evidenced by significant left-ward and up-ward shifts in ethanol generalization curves. Interestingly, VGB treatment was associated with slight increases in blood ethanol concentrations. The reduction in ethanol intake by VGB appears to be related to the ability of VGB to potentiate the pharmacological effects of ethanol. PMID:22336593

    There is concern within the Geoscience Community about the public's limited understanding of Earth Science and its fundamental contribution to society. Earth Science plays only a minor role in public school education in Ontario leaving many students to stumble upon this field of study in post-secondary institutions. As the Earth Sciences offer relevant advice for political decisions and provide excellent career opportunities, outreach is an increasingly important component of our work. Recruitment of post-secondary students after they have chosen their discipline cannot remain the sole opportunity. Outreach must be directed to potential students at an early stage of their education. High school teachers are influential, directing students towards professional careers. Therefore we are first committed to reach these teachers. We provide professional development, resources and continued support, building an enthusiastic community of educators. Specific initiatives include: a three day workshop supported by a grant from EdGEO introducing earth science exercises and local field destinations; a resource kit with minerals, rocks, fossils, mineral identification tools and manuals; a CD with prepared classroom exercises; and in-class demonstrations and field trip guiding on request. Maintaining a growing network with teachers has proven highly effective. Direct public school student engagement is also given priority. We inspire students through interaction with researchers and graduate students, hand-on exercises, and by providing opportunities to visit our department and work with our collections. Successful projects include our week-long course "School of Rock" for the Enrichment Mini-Course Program, classroom visits and presentations on the exciting and rewarding career paths in geology during Carleton University open houses. Outreach to the general public allows us to educate the wider community about the Geoheritage of our region, and initiate discussions about

    Previous experiences with people with both physical and intellectual functional diversity around palaeontological issues have demonstrated the important value of science outreach directed to people with disabilities. The aforementioned practices act twofold: as a learning tool and also improving the quality of life of the participants and thus, their self-image. All these pioneer experiences were the first step in a process of developing new attitudes contributing the 2030 Agenda for Sustainable Development of United Nations, where among the 17 goals proposed an effective social inclusion of people with disabilities is required. For this, real inclusive practices in geological outreach are imperious. A close cooperation with all the parts (researchers and participants), in a kind of coworking attitude is needed. This Inclusive-Coworking is considered in the sense of social gathering in order to share equal values and look for the synergy that this different outlook implies. And what is more important: the change of role of the previously learners into an active part of the scientific outreach, providing the adequate methodology for that. The offer of non-formal learning activities normally includes the participation of university professors and researchers in Science Week editions. During the 2016 session in Madrid, four adults with intellectual disability who were participants in the previous edition, contributed in the palaeontological workshop. They were in charge of four of the eight modules explaining the origin of fossils and how to collect them, the evolution of equids' limbs, and the main dentition types in vertebrates to the twenty 16 year old secondary students who attended the workshop. During the development of the experience all the students were pleased with the inclusive approach, and the interaction of all participants was fruitful. Although the explanations took a bit more time when made by our functional diverse fellows, all the abstracts concepts

  4. Sustainability of grape-ethanol energy chain

    Full Text Available The aim of this work is to evaluate the sustainability, in terms of greenhouse gases emission saving, of a new potential bio-ethanol production chain in comparison with the most common ones. The innovation consists of producing bio-ethanol from different types of no-food grapes, while usually bio-ethanol is obtained from matrices taken away from crop for food destination: sugar cane, corn, wheat, sugar beet. In the past, breeding programs were conducted with the aim of improving grapevine characteristics, a large number of hybrid vine varieties were produced and are nowadays present in the Viticulture Research Centre (CRA-VIT Germplasm Collection. Some of them are potentially interesting for bio-energy production because of their high production of sugar, good resistance to diseases, and ability to grow in marginal lands. Life cycle assessment (LCA of grape ethanol energy chain was performed following two different methods: i using the spreadsheet BioGrace, developed within the Intelligent Energy Europe program to support and to ease the Renewable Energy Directive 2009/28/EC implementation; ii using a dedicated LCA software. Emissions were expressed in CO2 equivalent (CO2eq. These two tools gave very similar results. The overall emissions impact of ethanol production from grapes on average is about 33 g CO2eq MJ–1 of ethanol if prunings are used for steam production and 53 g CO2eq MJ–1 of ethanol if methane is used. The comparison with other bio-energy chains points out that the production of ethanol using grapes represents an intermediate situation in terms of general emissions among the different production chains. The results showed that the sustainability limits provided by the normative are respected to this day. On the contrary, from 2017 this production will be sustainable only if the transformation processes will be performed using renewable sources of energy.

  5. High Speed/ Low Effluent Process for Ethanol

    n this project, BPI demonstrated a new ethanol fermentation technology, termed the High Speed/ Low Effluent (HS/LE) process on both lab and large pilot scale as it would apply to wet mill and/or dry mill corn ethanol production. The HS/LE process allows very rapid fermentations, with 18 to 22% sugar syrups converted to 9 to 11% ethanol ‘beers’ in 6 to 12 hours using either a ‘consecutive batch’ or ‘continuous cascade’ implementation. This represents a 5 to 8X increase in fermentation speeds over conventional 72 hour batch fermentations which are the norm in the fuel ethanol industry today. The ‘consecutive batch’ technology was demonstrated on a large pilot scale (4,800 L) in a dry mill corn ethanol plant near Cedar Rapids, IA (Xethanol Biofuels). The pilot demonstrated that 12 hour fermentations can be accomplished on an industrial scale in a non-sterile industrial environment. Other objectives met in this project included development of a Low Energy (LE) Distillation process which reduces the energy requirements for distillation from about 14,000 BTU/gal steam ($0.126/gal with natural gas @ $9.00 MCF) to as low as 0.40 KW/gal electrical requirements ($0.022/gal with electricity @ $0.055/KWH). BPI also worked on the development of processes that would allow application of the HS/LE fermentation process to dry mill ethanol plants. A High-Value Corn ethanol plant concept was developed to produce 1) corn germ/oil, 2) corn bran, 3) ethanol, 4) zein protein, and 5) nutritional protein, giving multiple higher value products from the incoming corn stream.

    The American Geophysical Union Space Physics and Aeronomy Section Education and Public Outreach Committee (AGU SPA-EPO Committee) was established in 1990 to foster the growth of a culture of outreach and community engagement within the SPA Section of the AGU. The SPA was the first AGU Section to establish an EPO Committee. The Committee has initiated several key Section EPO programs that have grown to become Union programs. NASA sponsored research is central to the mission of the SPE-EPO. Programs highlighting NASA research include the Student Paper Competition, Exploration Station, a precursor to the GIFT workshops, the Student mixer, and more. The Committee played a key role in coordinating the AGU's outreach activities relating to the International Heliophysical Year in 2007-2008. This paper will review the triumphs, the failures, and the lessons learned about recruiting colleagues to join with us from the last quarter century of effort.

    Nuclear energy generates significant reliable baseload electricity, yet many citizens in countries with nuclear power do not know the facts and benefits this clean energy source provides. For much of its history, the nuclear energy industry has been perceived as secretive and protective. Anti-nuclear activists use this general lack of public knowledge to sensationalise events, spread misinformation, and play on people's emotions. Yet, the nuclear energy industry has done little to combat these falsehoods imposed on the general public. Support for nuclear energy, or lack thereof, is even more pronounced after the extraordinary natural disasters and ensuing nuclear incident in Japan earlier this year, making proactive outreach to restore public trust even more important than before. The industry must inform and educate at all levels to dispel the falsehoods and enable clear, rational decision-making by government officials, business leaders and the general public, if it wants to grow and provide clean energy for the future. AREVA understands that this community outreach and education are just the first steps toward helping clean energy sources grow. We know that energy demand and security means we need to utilize every clean energy source available. We must start the education process from pre-school age to encourage children to enter science, technology, engineering and math curriculums. We must maintain regular community dialog and open discussions and operate in a safe manner, because in the long run, it is these community members who will help ensure energy security for the country. These stakeholders have a strong voice, a voice that can be heard locally, and if necessary, a voice that can impact the future of nuclear energy worldwide. As always, our industry is committed to the relentless pursuit of ever safer nuclear power. The nuclear industry as a whole must restore and win back trust. But the only way to restore this trust is by working together as an

    I investigate the influences of astronomy education and outreach activities on people in order to explore their potential benefits and contribution to society. This research is based on the astronomy education lessons I gave to 287 senior high school and junior high school students in Cambodia in November 2013. Before and after my lesson, I asked them to answer my questionnaires in Khmer, where they could also write free descriptions. Sentences in their free descriptions translated into Japanese are analyzed by means of a text mining method. By converting text data to various numbers using a text mining method, it is possible for us to do statistical analysis. I counted the number of question sentences and computed their rate with respect to the total number of sentences. The rate of question sentences in 9th and 12th grade students are 39% and 9%, respectively. This shows 9th grade students wonder why and how more frequently and appear to be more stimulated in their curiosity than 12th grade students. I counted the frequency of words in the free descriptions and examined high frequency words, to take a broad view of the characteristics of free description. The word ''world'' is the fourth highest frequency word among 369 words following the three words, ''the universe'', ''the earth'', and ''a star'', which frequently appear in the lesson in astronomy. The most sentences including the word “world” described amazement at the existence of so vast unknown world outside of what they had known until then. The frequency of sentences including the word ''world'' of 12th grade students is much higher (45%) than that (18%) of 9th grade students. A significant fraction of 12th grade students appears to have had a strong impact and changed their views of the world. It is found that my lesson and related activities inspired intellectual curiosity in many students, especially in 9th grade students. It is also found that a significant fraction of 12th grade students appear

    Dawn Education and Public Outreach strives to reach diverse learners using multi-disciplinary approaches. In-depth professional development workshops in collaboration with NASA's Discovery Program, MESSENGER and Stardust-NExT missions focusing on STEM initiatives that integrate the arts have met the needs of diverse audiences and received excellent evaluations. Another collaboration on NASA ROSES grant, Small Bodies, Big Concepts, has helped bridge the learning sequence between the upper elementary and middle school, and the middle and high school Dawn curriculum modules. Leveraging the Small Bodies, Big Concepts model, educators experience diverse and developmentally appropriate NASA activities that tell the Dawn story, with teachers' pedagogical skills enriched by strategies drawn from NSTA's Designing Effective Science Instruction. Dawn mission members enrich workshops by offering science presentations to highlight events and emerging data. Teachers' awareness of the process of learning new content is heightened, and they use that experience to deepen their science teaching practice. Activities are sequenced to enhance conceptual understanding of big ideas in space science and Vesta and Ceres and the Dawn Mission 's place within that body of knowledge Other media add depth to Dawn's resources for reaching students. Instrument and ion engine interactives developed with the respective science team leads help audiences engage with the mission payload and the data each instrument collects. The Dawn Dictionary, an offering in both audio as well as written formats, makes key vocabulary accessible to a broader range of students and the interested public. Further, as Dawn E/PO has invited the public to learn about mission objectives as the mission explored asteroid Vesta, new inroads into public presentations such as the Dawn MissionCast tell the story of this extraordinary mission. Asteroid Mapper is the latest, exciting citizen science endeavor designed to invite the

    In ancient times, past civilisations used to celebrate both the winter and summer solstices, which represented key moments in the periodical cycle of seasons and agricultural activities. In 1904, the French astronomer Camille Flammarion, the engineer Gustave Eiffel, the science writer Wilfrid de Fonvielle and the Spanish astronomer Josep Comas i Solà decided to celebrate the summer solstice with a festival of science, art and astronomical observations opened to the public at the Eiffel tower in Paris. For ten consecutive years (1904-1914) on the day of the summer solstice, the "Sun Festival" (Fête du Soleil in French) included scientific and technological lectures and demostrations, celestial observations, music, poetry, danse, cinema, etc. This celebration was interrupted by the First World War, just to resume in Barcelona, Spain, between 1915 and 1937, and in Marseille, France, in the 1930s. It was the founders' dream to extend this celebration to all cities in France and elsewhere.It is only during the International Year of Astronomy in 2009, to our knowledge, that the "Sun Festival" was given another chance in France, thanks to the joint effort of several scientific and cultural centers (Centres de Culture Scientifique, Technique et Industrielle, CCSTI) and the timely support of the European Space Agency (ESA). In this occasion again, the festival was characterized by the combination of science, art and technological innovation around a common denominator: our Sun!We have recently revived the idea of celebrating the summer solstice with a "Sun Festival" dedicated to scientific education and outreach about our star and related topics. This project started last year in Aix-les-Bains, France, with the "Sun and Light Festival" (2015 was the International Year of Light), attended by about 100 people. This year's second edition was in Le Bourget-du-Lac, France. Following the COP21 event, the specific theme was the "Sun and Climate Festival", and we had about 250

TwentyStreet Outreach Office professionals and six users collected the data, applying different semi-structured interview schedules for each category of participants. The resulting categories were analyzed in light of tool and ideological knowledge presented in the working process. From the participant discourses the following ideological knowledge emerged: public policies and the needs of the person ina street situation and tool knowledge, as well as devices and tools for the care of people in street situations and a weekly schedule. The focus on the working process discourse, supported by ideological knowledge, was verified. The structural dimension of the objective reality of the population in street situations was perceptible in the social determination of being situating on the street. When daily situations were revealed, the limitations to be overcome in the working process context were noticed.

    Baltimore faces a unique combination of shocks and stresses that cut across social, economic, and environmental sectors. Like many postindustrial cities, Baltimore has experienced a decline in its population - resulting in a lower tax base. These trends have had deleterious effects on the city's ability to attend to much needed infrastructure improvements and human services. Furthermore, Baltimore has an unfortunate history of deliberate racial segregation that is directly responsible for many of the economic and social challenges the City faces today. In addition to considerable social and economic issues, the city is already experiencing negative impacts from climate change. Baltimore is vulnerable to many natural hazards including heavy precipitation, sea level rise, storm surge, and extreme heat. Impacts from hazards and the capacity to adapt to them is not equal across all populations. Low-income residents and communities of color are most vulnerable and lack access to the resources to effectively plan, react and recover. They are also less likely to engage in government processes or input sessions, either due to distrust or ineffective outreach efforts by government employees and partners. This session is focused on sharing best practices and lessons learned from Baltimore's approach to community outreach and engagement as well as its focus on power shifting and relationship building with hard-to-reach communities. Reducing neighborhood vulnerability and strengthening the fabric that holds systems together requires a large number of diverse stakeholders coordinated around resiliency efforts. With the history of deliberate segregation and current disparities it remains critical to build trust, shift power from government to residents, and focus on relationship building. Baltimore City utilized this approach in planning, implementation and evaluation of resiliency work. This session will highlight two plan development processes, several projects, and innovative

Few outlets were able to accommodate and quickly share that amount of information as well as the Internet. To honor the 10-year anniversary of the launch of Terra, we would like to highlight the education and outreach efforts of the Terra mission on the Internet and its reach to the science attentive public. The Internet or web has been the primary way of delivering Terra content to different groups- from formal and informal education to general public outreach. Through the years, many different web-based projects have been developed, and they were of service to a growing population of the science attentive public. One of Terra’s original EPO activities was the Earth Observatory. It was initially dedicated to telling the remote sensing story of Terra, but quickly grew to include science and imagery from other sensors. The web site allowed for collaboration across NASA centers, universities and other organizations by exchanging and sharing of story ideas, news and images. The award winning Earth Observatory helped pave the way for the more recently funded development of the Climate Change website. With its specific focus on climate change studies, once again, Terra stories and images are shared with an even more specific audience base. During the last 10 years, Terra as a mission has captured the imagination of the public through its visually stunning and artistically arresting images. With its five instruments of complementary but unique capabilities, the mission gave the world not just pretty pictures, but scientific data-based images. The world was able to see from space everything from calving icebergs to volcanic eruption plumes and the eye of a

    Over the past six years I have made the transition from research oceanographer to an educator and public outreach specialist. The transition has been rewarding but difficult. On the way I had to learn the vocabulary and concepts of education (e.g. authentic assessment), effective web-page styles, and the difference between science and education--they are very different. I also met many enthusiastic and caring teachers who greatly eased my transition to educator. Some lessons learned. First, partner with experts. Successful outreach is a team effort. I was luck to have the opportunity to work closely with a great professor of education, Robert James, a wonderful middle-school teacher and Presidential Awardee, Margaret Hammer, and talented students, Jon Reisch and Don Johnson, from our School of ArchitectureAƒAøAøâ_sA¬Aøâ_zAøs Visualization Laboratory, who combined art and technology. Second, if you are a scientist, realize that scientists are too critical. We look for the one right answer, and for the flaws in data and theory. Educators look for the many ways to present ideas, all equally valid, and they value the worth of all students.

Second, the web is a very efficient way of reaching many people. Thus, web skills are essential. Third, I am learning to be humble. There is much I need to learn.

    ANDRILL field projects during the IPY included the McMurdo Ice Shelf (MIS) and Southern McMurdo Sound (SMS) drilling projects, and the Mackay Sea Valley (MSV) and Offshore New Harbor (ONH) seismic surveys. ANDRILL's international network of scientists, engineers, students and educators work together to convey an understanding of geoscience research and the process of science to non-technical audiences. ANDRILL education and public outreach (EPO) program goals are to: (1) promote environmental and polar science literacy for all audiences; (2) develop and disseminate engaging resources for formal and informal education; (3) develop and nurture a network of polar science educators; (4) spark the curiosity of students and the general public; (5) encourage students to pursue careers in science; (6) challenge misconceptions about scientific research; (7) provide professional development opportunities for educators; and, (8) encourage inquiry teaching in science education. During the IPY, ANDRILL established partnerships with several IPY projects to enhance science literacy and promote the IPY in formal and informal education and outreach venues. ANDRILL-led initiatives include the ARISE (ANDRILL Research Immersion for Science Educators) Program, Project Iceberg, the FLEXHIBIT (FLEXible exHIBIT; in partnership with Antarctica’s Climate Secrets/IPY Engaging Antarctica), and the Project Circle. ANDRILL partnerships developed with several museums and school districts for teacher professional development workshops and a variety of public events. A polar learning community was created from the ARISE participants and their many contacts, the Project Circle participants, and interested educators who contacted ANDRILL. EPO activities are continuing in the post-IPY period with additional funding. The ARISE program has been successful in building a team of educators and a network of international collaborations across grade levels and cultures. The ANDRILL website has expanded to

    A strain of Saccharomyces cerevisiae, which showed marked fermentation activity, ethanol and temperature tolerance and good flocculation ability, was selected for ethanol production. A stuck fermentation occurred at sucrose concentration of 25%. Increasing the yeast inoculum volume from 3% to 6% showed positive effects on fermentation from 25% sucrose. The ratio of added nitrogen to sucrose, which gave the best results (for the selected yeast strain), was determined. It was concluded that this ratio (nitrogen as ammonium sulphate at a rate of 5 mg g -1 of consumed sucrose) is constant at various sugar concentrations. Addition of nitrogen at this ratio produced 11.55% ethanol with complete consumption of 25% sucrose after 48 h of fermentation. However fermentation of 30% sucrose at the above optimum conditions was not complete. Addition of yeast extract at a level of 6 g l -1 together with thiamine at a level of 0.2 g l -1 led to complete utilization of 30% sucrose with resultant 14% ethanol production. However the selected yeast strain was not able to ferment 35% sucrose at the same optimum conditions. Addition of air at a rate of 150 dm 3 min -1 m 3 of reactor volume during the first 12 h of fermentation led to complete consumption of 35% sucrose and 16% ethanol was produced. This was approximately the theoretical maximum for ethanol production.

    American experience in the ethanol industry is discussed. Archer Daniel Midlands Co. (ADM) is a large agri-processing company that is the largest processor of grains and oilseeds, and processes ca 400,000 bushels of corn per day at its Decateur facility. Waste water and heat from the plant is used to grow vegetables hydroponically, with carbon dioxide from distillation used to speed growing at night. About 40,000 heads of lettuce per day are harvested, with cucumbers and tomatoes grown as premium crops. The plant includes a state-of-the-art fluidized bed power plant that burns high sulfur coal without sulfur emission. Approval has recently been granted by the Environmental Protection Agency to burn used tires, and payback for the process is expected to take 3-4 years. Ethanol is produced by steeping corn and separating germ and starch, with the starch used to make corn sweeteners. As well as ethanol, byproducts include animal feed, hydroponics, oils and margarines. ADM is the largest barging company in the U.S., with 14,000 rail cars, 1,200 dedicated to fuel ethanol. The Clean Air Act will mandate a 2.7% oxygen gasoline, and 10% ethanol additive gives 3.3% oxygen. The high octane rating of ethanol-blend gasoline is a strong selling point, and is a good deal for refiners, especially at octane-poor refineries.

    The emergence of antibiotic-resistant bacteria may limit the effectiveness of antibiotics to treat bacterial contamination in fuel ethanol plants, and therefore, new antibacterial intervention methods and tools to test their application are needed. Using shake-flask cultures of Saccharomyces cerevisiae grown on saccharified corn mash and strains of lactic acid bacteria isolated from a dry-grind ethanol facility, a simple model to simulate bacterial contamination and infection was developed. Challenging the model with 10(8) CFU/mL Lactobacillus fermentum decreased ethanol yield by 27% and increased residual glucose from 6.2 to 45.5 g/L. The magnitude of the effect was proportional to the initial bacterial load, with 10(5) CFU/mL L. fermentum still producing an 8% decrease in ethanol and a 3.2-fold increase in residual glucose. Infection was also dependent on the bacterial species used to challenge the fermentation, as neither L. delbrueckii ATCC 4797 nor L. amylovorus 0315-7B produced a significant decrease in ethanol when inoculated at a density of 10(8) CFU/mL. In the shake-flask model, treatment with 2 microg/mL virginiamycin mitigated the infection when challenged with a susceptible strain of L. fermentum (MIC for virginiamycin model may find application in developing new antibacterial agents and management practices for use in controlling contamination in the fuel ethanol industry.

    A strain of Saccharomyces cerevisiae, which showed marked fermentation activity, ethanol and temperature tolerance and good flocculation ability, was selected for ethanol production. A stuck fermentation occurred at sucrose concentration of 25%. Increasing the yeast inoculum volume from 3% to 6% showed positive effects on fermentation from 25% sucrose. The ratio of added nitrogen to sucrose, which gave the best results (for the selected yeast strain), was determined. It was concluded that this ratio (nitrogen as ammonium sulphate at a rate of 5 mg g{sup -1} of consumed sucrose) is constant at various sugar concentrations. Addition of nitrogen at this ratio produced 11.55% ethanol with complete consumption of 25% sucrose after 48 h of fermentation. However fermentation of 30% sucrose at the above optimum conditions was not complete. Addition of yeast extract at a level of 6 g l{sup -1} together with thiamine at a level of 0.2 g l{sup -1} led to complete utilization of 30% sucrose with resultant 14% ethanol production. However the selected yeast strain was not able to ferment 35% sucrose at the same optimum conditions. Addition of air at a rate of 150 dm{sup 3} min{sup -1} m{sup 3} of reactor volume during the first 12 h of fermentation led to complete consumption of 35% sucrose and 16% ethanol was produced. This was approximately the theoretical maximum for ethanol production. (author)

    Sensors containing metal-carbon nanotube (CNT) hybrid materials as the active sensing layer were demonstrated for ethanol vapor detection at room temperature. The metal-CNT hybrid materials were synthesized by infiltrating single wall carbon nanotubes (SWNTs) with the transition metals Ti, Mn, Fe, Co, Ni, Pd or Pt. Each sensor was prepared by drop-casting dilute dispersions of a metal-CNT hybrid onto quartz substrate electrodes and the impedimetric responses to varying ethanol concentration were recorded. Upon exposure to ethanol vapor, the ac impedance (Z') of the sensors was found to decrease to different extents. The sensor containing pristine CNT material was virtually non-responsive at low ethanol concentrations (<50 ppm). In contrast, all metal-CNT hybrid sensors showed extremely high sensitivity to trace ethanol levels with 100-fold or more gains in sensitivity relative to the starting SWNT sensor. All hybrid sensors, with the exception of Ni filled CNT, exhibited significantly larger sensor responses to ethanol vapor up to 250 ppm compared to the starting SWNT sensor.

    For energy security, air pollution concerns, coupled with the desire to sustain the agricultural sector and revitalize the rural economy, many countries have applied ethanol as oxygenate or fuel to supplement or replace gasoline in transportation sector. Because of abundant feedstock resources and effective reduction of green-house-gas emissions, the cellulosic ethanol has attracted great attention. With a couple of pioneers beginning to produce this biofuel from biomass in commercial quantities around the world, it is necessary to solve engineering problems and complete the economic assessment in 2015-2016, gradually enter the commercialization stage. To avoid "competing for food with humans and competing for land with food", the 1st generation fuel ethanol will gradually transit to the 2nd generation cellulosic ethanol. Based on the overview of cellulosic ethanol industrialization from domestic and abroad in recent years, the main engineering application problems encountered in pretreatment, enzymes and enzymatic hydrolysis, pentose/hexose co-fermentation strains and processes, equipment were discussed from chemical engineering and biotechnology perspective. The development direction of cellulosic ethanol technology in China was addressed.

    We report here for the first time a thermodynamic study of gaseous ethanol sorption on raw cork powder and plate. Our study aims at a better understanding of the reactivity of this material when used as a stopper under enological conditions, thus in close contact with a hydroethanolic solution, wine. Sorption−desorption isotherms were accurately measured by thermogravimetry at 298 K in a large range of relative pressures. Sorption enthalpies were determined by calorimetry as a function of loading. Sorption−desorption isotherms exhibit a hysteresis loop probably due to the swelling of the material and the absorption of ethanol. Surprisingly, the sorption enthalpy of ethanol becomes lower than the liquefaction enthalpy as the filling increases. This result could be attributed to the swelling of the material, which would generate endothermic effects. Sorption of SO₂ on cork containing ethanol was also studied. When the ethanol content in cork is 2 wt %, the amount of SO₂ sorbed is divided by 2. Thus, ethanol does not enhance the sorption rate for SO₂ but, on the contrary, decreases the SO₂ sorption activity onto cork, probably because of competitive sorption mechanisms.

    Astronomy outreach is often conducted in science classrooms, museums, observatories, and even at the local park. The intended audiences are usually families with young children, who we are training to be the next generation of scientists, inventors and world-changers. Science outreach is rarely geared towards senior citizens, and yet this group can be the most receptive audience, willing to share past experiences and engage in learning. Educating our seniors about astronomy, especially current discoveries, upcoming technology, and funding challenges, is of the utmost importance. Here, I share my experience conducting astronomy outreach at senior living communities in Rochester, NY as part of their Lifelong Learning initiative, and discuss why this type of outreach is important.

    NONE

    2007-03-15

    This paper provided the results of a survey conducted to obtain feedback from retailers and provincial and territorial governments concerning the promotion of ethanol use. A key objective of the research was to determine whether local and provincial governments and retailers are interested in cooperating with the federal government in promoting ethanol use. Thirteen government representatives were interviewed as well as 11 retailers. Results of the study suggested that approaches to collaboration with the diverse stakeholders involved in the promotion of ethanol will require a tailored approach. The needs and interests of jurisdictions and provinces varied widely. Outlets selling ethanol-blended gasoline were concentrated in Ontario, Quebec, and Saskatchewan. Retailers who embraced the alternative fuel tended to be well-established in the ethanol market, and did not require assistance from the Government of Canada. Retailers who were reluctant to embrace ethanol stated that they were only likely to enter the market when required to do so by law. Many stakeholders felt that consumers entertained common misperceptions concerning ethanol, and that consumers were unsure of the effect of ethanol on their vehicles. Many retailers had taken steps to communicate with consumers about the relative benefits of ethanol-blended gasoline. Results indicated that the federal government can assist provinces and retailers by providing promotional tools such as flyers, pamphlets and brochures. Interest among retailers in collaborating with the government was only moderate. It was recommended that retailers be provided with accurate information on ethanol. It was concluded that strategies should be developed by the federal government to increase public awareness of ethanol use.

  17. Ligno-ethanol in competition with food-based ethanol in Germany

    International Nuclear Information System (INIS)

    Poganietz, Witold-Roger

    2012-01-01

    First-generation biofuels are often challenged over their potentially adverse impact on food prices. Biofuels that use nonfood biomass such as lignocellulose are being promoted to ease the conflict between fuels and food. However, their complex processes mean that the total costs of lignocellulosic ethanol may be high in comparison. This might undermine the economic soundness of plans for its use. Another potential advantage of lignocellulosic ethanol is seen in an enhanced contribution to a reduction in greenhouse gas emissions. Yet the increasing attractiveness of lignocellulosic biofuels may also lead to changes in land use that induce additional carbon emissions. For this reason, the environmental impacts of such plans are not straightforward and depend on the affected category of land. The objective of this paper is to compare the economic perspectives and environmental impact of lignocellulosic ethanol with food-based ethanol taking into account market constraints and policy measures. The analysis of the environmental impact focuses on carbon dioxide emissions. In the medium run, i.e., by 2020, lignocellulosic ethanol could enter the gasoline market, crowding out inter alia food-based ethanol. In terms of carbon dioxide emissions, lignocellulosic ethanol seems to be environmentally desirable in each of the analyzed cases. The findings depend crucially on the market conditions, which are influenced inter alia by crude oil, the exchange rate, and technology conditions. -- Highlights: ► Competition of ligno-ethanol with competing energy carriers is analyzed. ► In medium-term ligno-ethanol could crowd out food-based ethanol. ► In terms of CO 2 ligno-ethanol seems to be environmentally desirable. ► The environmental impacts include by land use change induced CO 2 emissions. ► The findings depend crucially on market conditions.

  18. Chronic intermittent ethanol exposure during adolescence: effects on social behavior and ethanol sensitivity in adulthood.

    This study assessed long-lasting consequences of repeated ethanol exposure during two different periods of adolescence on 1) baseline levels of social investigation, play fighting, and social preference and 2) sensitivity to the social consequences of acute ethanol challenge. Adult male and female Sprague-Dawley rats were tested 25 days after repeated exposure to ethanol (3.5 g/kg intragastrically [i.g.], every other day for a total of 11 exposures) in a modified social interaction test. Early-mid adolescent intermittent exposure (e-AIE) occurred between postnatal days (P) 25 and 45, whereas late adolescent intermittent exposure (l-AIE) was conducted between P45 and P65. Significant decreases in social investigation and social preference were evident in adult male rats, but not their female counterparts following e-AIE, whereas neither males nor females demonstrated these alterations following l-AIE. In contrast, both e-AIE and l-AIE produced alterations in sensitivity to acute ethanol challenge in males tested 25 days after adolescent exposure. Ethanol-induced facilitation of social investigation and play fighting, reminiscent of that normally seen during adolescence, was evident in adult males after e-AIE, whereas control males showed an age-typical inhibition of social behavior. Males after l-AIE were found to be insensitive to the socially suppressing effects of acute ethanol challenge, suggesting the development of chronic tolerance in these animals. In contrast, females showed little evidence for alterations in sensitivity to acute ethanol challenge following either early or late AIE. The results of the present study demonstrate a particular vulnerability of young adolescent males to long-lasting detrimental effects of repeated ethanol. Retention of adolescent-typical sensitivity to the socially facilitating effects of ethanol could potentially make ethanol especially appealing to these males, therefore promoting relatively high levels of ethanol intake later

    The Ionospheric Radio Science Laboratory (IRSL) at Institute of Space Science, National Central University in Taiwan has been conducting a program for public outreach educations on space science by giving lectures, organizing camps, touring exhibits, and experiencing hand-on experiments to elementary school, high school, and college students as well as general public since 1991. The program began with a topic of traveling/living in space, and was followed by space environment, space mission, and space weather monitoring, etc. and a series of course module and experiment (i.e. experiencing activity) module was carried out. For past decadal, the course modules have been developed to cover the space environment of the Sun, interplanetary space, and geospace, as well as the space technology of the rocket, satellite, space shuttle (plane), space station, living in space, observing the Earth from space, and weather observation. Each course module highlights the current status and latest new finding as well as discusses 1-3 key/core issues/concepts and equip with 2-3 activity/experiment modules to make students more easily to understand the topics/issues. Meanwhile, scientific camps are given to lead students a better understanding and interesting on space science. Currently, a visualized image projecting system, Dagik Earth, is developed to demonstrate the scientific results on a sphere together with the course modules. This system will dramatically improve the educational skill and increase interests of participators.

  5. Public Outreach Guerilla Style: Just Add Science to Existing Events

    2016-01-01

    We report on a campaign to use the visual appeal of astronomy as a gateway drug to inject public outreach into settings where people aren't expecting an encounter with science. Our inspiration came from the team at guerillascience.org, who have earned a reputation for creating, at sites around the world, "experiences and events that are unexpected, thought-provoking, but, above all, that delight and entertain." Our goal is to insert astronomy into existing festivals of music, culture, and art; county and state fairs; sporting events; and local farmer's markets. With volunteers and near-zero budgets, we have been able to meaningfully engage with audience members who would never willingly attend an event advertised as science related. By purposefully relating astronomy to the non-science aspects of the event that caused the audience members to attend, new learning experiences are created that alter the often negative pre-conceived notions about science that many of them held before our encounter.

    We present an overview of the Lowell Observatory Navajo-Hopi Astronomy Outreach Program, which is modeled after the ASP's Project ASTRO (Richter & Fraknoi 1994). Since 1996, our missions have been (1) to use the inherent excitement about the night sky to help teachers get Navajo and Hopi students excited about science and education, and (2) to help teachers of Navajo and Hopi students learn about astronomy and hands-on activities so that they will be better able to incorporate astronomy in their classrooms. Lowell astronomers pair up for a school year with an elementary or middle school (5th-8th grade) teacher and make numerous visits to their teachers' classes, partnering with the educators in leading discussions linked with hands-on activities. Lowell staff also work with educators and amateur astronomers to offer evening star parties that involve the family members of the students as well as the general community. Toward the end of the school year, teachers bring their classes to Lowell Observatory. The classes spend some time exploring the Steele Visitor Center and participating in tours and programs. They also voyage to Lowell's research facility in the evening to observe at two of Lowell's research telescopes. Furthermore, we offer biennial teacher workshops in Flagstaff to provide teachers with tools, curricula materials, and personalized training so that they are able to include astronomy in their classrooms. We also work with tribal educators to incorporate traditional astronomical knowledge. Funding for the program comes from many different sources.

  7. Self-efficacy of college freshmen engaged in STEM outreach

    Patchin, Stephen H.

    Not since the Cold War and the launch of Sputnik has there been such a focus on producing college graduates in fields related to science, technology, engineering, and mathematics (STEM). As manually driven careers disappear, new diverse careers are created and they have one thing in common, STEM. As students move into these challenging curriculums they will need to have faith in their abilities to achieve their goals. This self-efficacy is vital component for their collegiate and career success. This mixed methods study examines the unique pre-college STEM outreach phenomenon called Mind Trekkers. Mind Trekkers uses the "WOW" of experiential learning in the areas of STEM to motivate K-12 students to engage in STEM related fields. The focus of the study is on the first-year college freshmen that join this program, becoming STEM serviceteers, and how being part of this STEM phenomenon impacts their self-efficacy. The findings can be summed up in a quote. I get to help people understanding in a different way than I would if I was just doing volunteering like I did in high school. It's cool. I just love it and it gives me the confidence that what I am doing is the right thing here at (the university). (Jean). The results of the study indicate that the Mind Trekkers program acted as a catalyst to increase the self-efficacy of the students that participated in it, through personal social and academic impact.

  8. Engaging high school students as plasma science outreach ambassadors

    2017-10-01

    Exposure to plasma science among future scientists and engineers is haphazard. In the U.S., plasma science is rare (or absent) in mainstream high school and introductory college physics curricula. As a result, talented students may be drawn to other careers simply due to a lack of awareness of the stimulating science and wide array of fulfilling career opportunities involving plasmas. In the interest of enabling informed decisions about career options, we have initiated an outreach collaboration with the Madison West High School Rocket Club. Rocket Club members regularly exhibit their activities at public venues, including large-scale expos that draw large audiences of all ages. Building on their historical emphasis on small scale rockets with chemical motors, we worked with the group to add a new feature to their exhibit that highlights plasma-based spacecraft propulsion for interplanetary probes. This new exhibit includes a model satellite with a working (low power) plasma thruster. The participating high school students led the development process, to be described, and enthusiastically learned to articulate concepts related to plasma thruster operation and to compare the relative advantages of chemical vs. plasma/electrical propulsion systems for different scenarios.

    An innovative partnership among academia, government, and private industry has created a unique opportunity for oceanographic and meteorological research on a cruise ship. The University of Miami's Rosenstiel School of Marine and Atmospheric Science, Royal Caribbean International, the National Oceanic and Atmospheric Administration's Atlantic Oceanographic and Meteorological Laboratory the National Science Foundation, and the U.S. Office of Naval Research have collaborated to establish two modern laboratories for oceanic and atmospheric research on the 142,000-ton Royal Caribbean ship Explorer of the Seas.The Explorer of the Seas combines extensive research capabilities with public outreach. Hundreds of passengers experience the planet's atmosphere-ocean systems through laboratory tours and presentations given by experienced guest scientists and graduate students. In addition to weekly public lectures, guided tours of the ocean and atmospheric laboratories are available, and ocean-related films are shown during selected afternoons. Two interactive eco-learning areas onboard are equipped with a series of interactive displays and large informational touch screens that illustrate marine and atmospheric concepts as well as the onboard research program.

    Conservation education and outreach programs are a key approach to promote public understanding of the importance of biodiversity conservation. We reviewed 85 biodiversity conservation projects supported by the Spanish Ministry of Environment's Biodiversity Foundation. Through content analysis and descriptive statistics, we examined how the projects carried out communication, education, and public awareness and participation (CEPA) actions. We also used multivariate statistical analysis to develop a typology of 4 classes of biodiversity conservation projects on the basis of CEPA implementation. The classifications were delineated by purpose of CEPA, level of integration of CEPA actions, type of CEPA goals, main CEPA stakeholders, and aim of conservation. Our results confirm the existence of 2 key positions: CEPA has intrinsic value (i.e., they supposed the implementation of any CEPA action indirectly supported conservation) and CEPA is an instrument for achieving conservation goals. We also found that most CEPA actions addressed general audiences and school children, ignored minority groups and women, and did not include evaluation. The characteristics of the 4 types of projects and their frequency of implementation in the sample reflect the need for better integration of different types of actions (communication, education, and participation) and improved fostering of participation of multiple stakeholders in developing policy and implementing management strategies. © 2014 Society for Conservation Biology.

    Full Text Available This paper describe the impacts and lessons learned of using conferencing technologies to support knowledge production activities within an academic detailing group. A three year case study was conducted in which 20 Canadian health professionals collaborated on developing educational outreach materials for family physicians. The groups communicated in face-to-face, teleconferencing, and web-conferencing environments. Data was collected over three years (2004-2007 and consisted of structured interviews, meeting transcripts, and observation notes. The analysis consisted of detailed reviews and comparisons of the data from the various sources. The results revealed several key findings on the on the impacts of conferencing technologies on knowledge production activities of academic detailers. The study found that: 1 The rigid communication structures of web-conferencing forced group members to introduce other tools for communication 2 Group discussions were perceived to be more conducive in face-to-face meetings and least conducive teleconferencing meetings; 3 Web-conferencing had an impact on information sharing; 4 Web-conferencing forces group interaction “within the text”. The study demonstrates the impacts and lessons learned of academic detailing groups collaborating at a distance to produce physician education materials. The results can be used as the bases for future research and as a practical guide for collaborative academic detailing groups working within a virtual collaborative and educational environment.

    The Los Alamos Space Science Outreach (LASSO) program features summer workshops in which K-14 teachers spend several weeks at LANL learning space science from Los Alamos scientists and developing methods and materials for teaching this science to their students. The program is designed to provide hands-on space science training to teachers as well as assistance in developing lesson plans for use in their classrooms. The program supports an instructional model based on education research and cognitive theory. Students and teachers engage in activities that encourage critical thinking and a constructivist approach to learning. LASSO is run through the Los Alamos Science Education Team (SET). SET personnel have many years of experience in teaching, education research, and science education programs. Their involvement ensures that the teacher workshop program is grounded in sound pedagogical methods and meets current educational standards. Lesson plans focus on current LANL satellite projects to study the solar wind and the Earth's magnetosphere. LASSO is an umbrella program for space science education activities at Los Alamos National Laboratory (LANL) that was created to enhance the science and math interests and skills of students from New Mexico and the nation. The LASSO umbrella allows maximum leveraging of EPO funding from a number of projects (and thus maximum educational benefits to both students and teachers), while providing a format for the expression of the unique science perspective of each project.

    2011-07-01

    A convergence between astronomy science and digital photography has enabled a steady stream of visually rich imagery from state-of-the-art data. The accessibility of hardware and software has facilitated an explosion of astronomical images for outreach, from space-based observatories, ground-based professional facilities and among the vibrant amateur astrophotography community. Producing imagery from science data involves a combination of custom software to understand FITS data (FITS Liberator), off-the-shelf, industry-standard software to composite multi-wavelength data and edit digital photographs (Adobe Photoshop), and application of photo/image-processing techniques. Some additional effort is needed to close the loop and enable this imagery to be conveniently available for various purposes beyond web and print publication. The metadata paradigms in digital photography are now complying with FITS and science software to carry information such as keyword tags and world coordinates, enabling these images to be usable in more sophisticated, imaginative ways exemplified by Sky in Google Earth and World Wide Telescope.

    Coastal oceans are dynamic, changing environments affected by processes ranging from seconds to millennia. On the east and west coast of the U.S., regional observing systems have deployed and sustained a remarkable diverse array of observing tools and sensors. Data portals visualize and provide access to real-time sensor networks. Portals have emerged as an interactive tool for educators to help students explore and understand climate. Bringing data portals to outreach events, into classrooms, and onto tablets and smartphones enables educators to address topics and phenomena happening right now. For example at the 2015 Charleston Science Technology Engineering and Math (STEM) Festival, visitors navigated the SECOORA (Southeast Coastal Ocean Observing regional Association) data portal to view the real-time marine meteorological conditions off South Carolina. Map-based entry points provide an intuitive interface for most students, an array of time series and other visualizations depict many of the essential principles of climate science manifest in the coastal zone, and data down-load/ extract options provide access to the data and documentation for further inquiry by advanced users. Beyond the exposition of climate principles, the portal experience reveals remarkable technologies in action and shows how the observing system is enabled by the activity of many different partners.

    Coe College is a private liberal arts college nestled in the northeast quadrant of Cedar Rapids, IA. Coe takes pride in the outreach it does in the local community. The sciences at Coe find enjoyment in educating the children and families of this community through a diverse set of venues; from performing science demonstrations for children at Cedar Rapids' Fourth of July Freedom Festival to hosting summer forums and talks to invigorate the minds of its more mature audiences. Among these events, the signature event of the year is the Coe Playground of Science. On the last Thursday of October, before Halloween, the science departments at Coe invite nearly two thousand children from pre elementary to high school ages, along with their parents to participate in a night filled with science demos, haunted halls, and trick-or-treating for more than just candy. The demonstrations are performed by professors and students alike from a raft of cooperative departments including physics, chemistry, biology, math, computer science, nursing, ROTC, and psychology. This event greatly strengthens the relationships between institution members and community members. The sciences at Coe understand the importance of imparting the thrill and hunger for exploration and discovery into the future generations. More importantly they recognize that this cannot start and end at the collegiate level, but the American public must be reached at younger ages and continue to be encouraged beyond the college experience. The Playground of Science unites these two groups under the common goal of elevating scientific interest in the American people.

    Appalachian State University will provide a variety of observing opportunities for the public during the International Year of Astronomy. These will be focused at both the campus GoTo Telescope Facility used by Introductory Astronomy students and the research facilities at our Dark Sky Observatory. The campus facility is composed of a rooftop deck with a roll-off roof housing fifteen Celestron C11 telescopes. During astronomy lab class meetings these telescopes are used either in situ or remotely by computer control from the adjacent classroom. For the IYA we will host the public for regular observing sessions at these telescopes. The research facility features a 32-inch DFM Engineering telescope with its dome attached to the Cline Visitor Center. The Visitor Center is still under construction and we anticipate its completion for a spring opening during IYA. The CVC will provide areas for educational outreach displays and a view of the telescope control room. Visitors will view celestial objects directly at the eyepiece. We are grateful for the support of the National Science Foundation, through grant number DUE-0536287, which provided instrumentation for the GoTO facility, and to J. Donald Cline for support of the Visitor Center.

    In May 2012 the CANDELS collaboration launched a public outreach blog, aimed at the general public, where we discuss CANDELS related science. CANDELS (the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey) is a large Hubble Space Telescope Multi-Cycle Treasury Program to image portions of the five most commonly studied deep fields in the near-infrared with WFC3. This large collaboration encompasses a wide range of science topics including galaxy evolution and observational cosmology. We seek to understand how galaxies in the early universe formed and evolved to become the galaxies we see today. We post on a wide variety of topics including general background discussion on many issues in extragalactic astronomy, current science results and papers, highlights from meetings that we have attended, and what life as an astronomer is like (going on observing runs, writing proposals, and how we became interested in astronomy). The posts are written by a large number of collaboration members at different career stages (including students, postdocs, and permanent staff/faculty members) and is widely read and advertised on Facebook, Twitter, and Google+.

    The widespread availability of portable computers in the form of smartphones provides a unique opportunity to introduce scientific concepts to a broad audience, for the purpose of education, or for the purpose of sharing exciting developments and research. Unity, a free game development platform, has been used to develop a program to visualize 3-D events from a Time Projection Chamber (TPC). The program can be presented as a Virtual Reality (VR) application on a smartphone, which can serve as a standalone demonstration for interested individuals, or as a resource for educators. An interactive experience to watch nuclear events unfold demonstrates the principles of particle detection with a TPC, as well as providing information about the particles present. Different kinds of reactions can be showcased. The current state of tools within this program for outreach and educational purposes will be highlighted and presented in this poster, along with key design concerns and optimizations necessary for running an interactive VR app. The events highlighted in this program are from the S πRIT TPC, but the program can be applied to other 3-D detectors. This work is supported by the U.S. Department of Energy under Grant Nos. DE-SC0014530, DE-NA0002923 and US NSF under Grant No. PHY-1565546.

    Astronomical images in the public domain have increasingly been used as inspiration and patterns for clothing, accessories, and home decor. These 'AstroFashion' items are as diverse as DIY projects, handmade and boutique products, mass-produced commercial items, and haute couture. STARtorialist is a Tumblr-based blog that curates the proliferation of these products with the goal of celebrating the beauty of the universe and highlighting the science behind the images. The blog also includes sci-fi, space, and science-related aspects of popular culture. Each post features images and descriptions of the products, and often where/how we found them and/or the people wearing them, with links to the original astronomical images or other relevant science content. The popularity of each post is evident in the number of 'notes', including 'faves' (personal bookmarks) and 'reblogs' (shares with other users). Since launching the blog in December 2013, with an average of one post per day, we've attracted hundreds of followers on Tumblr and Twitter and thousands of notes on Tumblr. We will present our most popular posts and recommend how education, outreach, and press offices can add Tumblr to their social media repertoire.

    In this paper, we will present the current status of radio astronomical research and outreach in Malaysia. We will also present a short history of our research group, which is currently the only radio astronomical facility in Malaysia. Our group is called the Radio Cosmology Research Lab and was established in 2005 by Dr Zamri Zainal Abidin and Prof Dr Zainol Abidin Ibrahim. We will discuss the future plans for this group including our keen interest in being part of a more global network of radio astronomers. We are already an active member of the South-East Asia Astronomy Network (SEAAN) and aims to have a radio astronomical facility in order to join the Global Very Long Baseline Interferometer (VLBI) as well becoming a research hub for the future Square Kilometer Array (SKA) project. We will also present some of the scientific goals of our group including providing a platform for radio astronomers to be able to do observations of weak and high red-shifted radio objects such as galaxy clusters and supernovae.

  1. Using Virtual Reality For Outreach Purposes in Planetology

    2016-10-01

    2016 has been a year marked by a technological breakthrough : the availability for the first time to the general public of technologically mature virtual reality devices. Virtual Reality consists in visually immerging a user in a 3D environment reproduced either from real and/or imaginary data, with the possibility to move and eventually interact with the different elements. In planetology, most of the places will remain inaccessible to the public for a while, but a fleet of dedicated spacecraft's such as orbiters, landers and rovers allow the possibility to virtually reconstruct the environments, using image processing, cartography and photogrammetry. Virtual reality can then bridge the gap to virtually "send" any user into the place and enjoy the exploration.We are investigating several type of devices to render orbital or ground based data of planetological interest, mostly from Mars. The most simple system consists of a "cardboard" headset, on which the user can simply use his cellphone as the screen. A more comfortable experience is obtained with more complex systems such as the HTC vive or Oculus Rift headsets, which include a tracking system important to minimize motion sickness. The third environment that we have developed is based on the CAVE concept, were four 3D video projectors are used to project on three 2x3m walls plus the ground. These systems can be used for scientific data analysis, but also prove to be perfectly suited for outreach and education purposes.

  2. Outcomes for engineering students delivering a STEM education and outreach programme

    2017-11-01

    University science outreach programmes are used to encourage more school students to select science, technology, engineering, and mathematics (STEM) subjects in further education and pursue science-related careers. The benefits of science outreach programmes are often espoused from the perspective of programme participants. Little attention, however, is given to what university students delivering the programmes gain from the experience. This paper seeks to illustrate the benefits of engineering students delivering STEM outreach programmes in schools. It reports on a qualitative case study of the experiences of two STEM Education and Outreach team members from a regional university in Australia. Content analysis of interview data highlighted not only the participants' motivations and perceived benefits of being involved in the STEM programme but also revealed the skills and attributes honed throughout the experience. Involvement in the STEM outreach programme resulted in the development of social and personal responsibility generic graduate attribute skills, evidenced through their motivations to be involved, the demonstration of understanding of teaching and learning, and application of science communication skills. This study demonstrates that designing and delivering STEM outreach programmes assists in the development of skills that will be beneficial when pursuing careers in engineering in the future.

    Education, outreach, advertising, and training programs provide particular difficulties in evaluation, as they focus on modifying behaviors and purchases rather than directly installing measures. This paper summarizes the results of a literature review of more than 80 studies evaluating strengths and weaknesses of evaluation work on outreach and education programs. Then, the paper presents the results of several applications of advanced evaluation techniques that are being applied to outreach, education, and training programs. This paper provides the results from detailed net-to-gross (NTG) and non-energy benefits (NEB) evaluations of outreach, training, and education programs, including:A training and education geared toward commercial architects and engineers; Two similar programs geared toward residential builders and remodelers; Residential appliance-related education and outreach programs (Energy Star); and An information-based university program.We provide information from detailed evaluations of the share of energy savings and attributable effects that are due to the program's efforts (net-to-gross ratio), and the non-energy benefits (NEBs) recognized by participants. These results augment the usual evaluation studies, and provide insights that can guide informational, outreach, and training programs to maximize their effectiveness. The attribution and NEB results provide a fuller picture of the benefits from the program, support more sophisticated benefit-cost analysis, provide direction for maximizing program 'bang for the buck', and help support program decision-making and marketing.

    Liu, Gang; Bao, Jie

    2017-12-01

    Energy consumption and wastewater generation in cellulosic ethanol production are among the determinant factors on overall cost and technology penetration into fuel ethanol industry. This study analyzed the energy consumption and wastewater generation by the new biorefining process technology, dry acid pretreatment and biodetoxification (DryPB), as well as by the current mainstream technologies. DryPB minimizes the steam consumption to 8.63GJ and wastewater generation to 7.71tons in the core steps of biorefining process for production of one metric ton of ethanol, close to 7.83GJ and 8.33tons in corn ethanol production, respectively. The relatively higher electricity consumption is compensated by large electricity surplus from lignin residue combustion. The minimum ethanol selling price (MESP) by DryPB is below $2/gal and falls into the range of corn ethanol production cost. The work indicates that the technical and economical gap between cellulosic ethanol and corn ethanol has been almost filled up. Copyright © 2017 Elsevier Ltd. All rights reserved.

  6. Market penetration of biodiesel and ethanol

    Science.gov (United States)

    Szulczyk, Kenneth Ray

    This dissertation examines the influence that economic and technological factors have on the penetration of biodiesel and ethanol into the transportation fuels market. This dissertation focuses on four aspects. The first involves the influence of fossil fuel prices, because biofuels are substitutes and have to compete in price. The second involves biofuel manufacturing technology, principally the feedstock-to-biofuel conversion rates, and the biofuel manufacturing costs. The third involves prices for greenhouse gas offsets. The fourth involves the agricultural commodity markets for feedstocks, and biofuel byproducts. This dissertation uses the Forest and Agricultural Sector Optimization Model-Greenhouse Gas (FASOM-GHG) to quantitatively examine these issues and calculates equilibrium prices and quantities, given market interactions, fossil fuel prices, carbon dioxide equivalent prices, government biofuel subsidies, technological improvement, and crop yield gains. The results indicate that for the ranges studied, gasoline prices have a major impact on aggregate ethanol production but only at low prices. At higher prices, one runs into a capacity constraint that limits expansion on the capacity of ethanol production. Aggregate biodiesel production is highly responsive to gasoline prices and increases over time. (Diesel fuel price is proportional to the gasoline price). Carbon dioxide equivalent prices expand the biodiesel industry, but have no impact on ethanol aggregate production when gasoline prices are high again because of refinery capacity expansion. Improvement of crop yields shows a similar pattern, expanding ethanol production when the gasoline price is low and expanding biodiesel. Technological improvement, where biorefinery production costs decrease over time, had minimal impact on aggregate ethanol and biodiesel production. Finally, U.S. government subsidies have a large expansionary impact on aggregate biodiesel production. Finally, U.S. government

  7. Presentation to the Manitoba ethanol advisory panel

    International Nuclear Information System (INIS)

    2002-01-01

    The Manitoba Chambers of Commerce, representing the entire spectrum of businesses from all regions of Manitoba, has long advocated for alternative fuels based on agricultural products. Some of the major questions that must be answered in this debate on the ethanol industry in Manitoba are: (1) What are the benefits of a vibrant ethanol industry? (2) What are the facts about ethanol, and are those facts getting out to the public? (3) and How do we foster a vibrant ethanol industry in Manitoba? This document places the emphasis on the third issue raised. The Manitoba Chambers of Commerce endorses the idea of a mandated blend of ethanol. It also believes that Manitoba should maintain its gasoline tax-gasohol preference. The Manitoba Chambers of Commerce recommends against the government controlling the size and number of ethanol facilities in the province. It also recommends that funding not be afforded to the creation of new programs designed for the specific purpose of providing financial assistance to the ethanol industry. Government awareness campaigns should be limited to issues within the public interest, dealing with environmental and consumer issues and benefits. The government should commit to the enhancement of the vitality of new generation cooperatives (NGCs) in Manitoba. Emphasis by the government should be placed on ensuring that the required infrastructure and partnerships are in place to foster the development and commercialization of innovations in this field. The Manitoba Chambers of Commerce recommended that the provincial government facilitate partnerships through the sponsoring of provincial conferences, while pursuing its partnership efforts with the federal and other provincial governments

  8. Ethanol: the promise and the peril : Should Manitoba expand ethanol subsidies?

    2002-01-01

    Ethanol is produced through the fermentation of wheat. Blending ethanol with gasoline results in an ethanol-blended gasoline (EBG). Manitoba has already established an ethanol industry in the province and the government of the province is studying the feasibility of expansion. Every year in Manitoba, approximately 90 million litres of EBG are consumed, and the province's ethanol facility also produces a high protein cattle feed called distillers dry grain. Controversies surround the ethanol industry over both the economics and the environmental benefits and impacts. At issue is the economic efficiency of the production of ethanol, where opponents claim that the final product contains less energy than that required to produce it. A small gain is obtained, as revealed by a recent study. It is difficult to quantify the environmental effects of the ethanol industry, whether they be negative or positive. The author indicates that no matter what happens, the gasoline market in Manitoba is so small when compared to the rest of the world that the effect will not be significant. The three methods for the production of ethanol are: (1) the most risky and expensive method is the stand alone ethanol production facility, (2) integrated facilities where other products are produced, such as wet mash or nutraceuticals, and (3) integrated facilities where dry mash can be exported as a high protein feed. The production of a wide range of products is clearly the best option to be considered during the design of an ethanol facility. Price collapse and the capitalizing of subsidies into prices are the main risks facing the expansion of ethanol production in Manitoba. The author states that direct subsidies and price supports should be avoided, since subsidies would encourage the conversion of more feed grain into ethanol. The feed shortage would worsen especially as Manitoba does not currently produce enough feed to support its growing livestock industry. The author concludes that

    Outreach has been endorsed as an important global strategy to promote universal access to health care but it depends on health workers who are willing to travel. In Australia, rural outreach is commonly provided by specialist doctors who periodically visit the same community over time. However information about the level of participation and the distribution of these services nationally is limited. This paper outlines the proportion of Australian specialist doctors who participate in rural outreach, describes their characteristics and assesses how these characteristics influence remote outreach provision. We used data from the Medicine in Australia: Balancing Employment and Life (MABEL) survey, collected between June and November 2008. Weighted logistic regression analyses examined the effect of covariates: sex, age, specialist residential location, rural background, practice arrangements and specialist group on rural outreach. A separate logistic regression analysis studied the effect of covariates on remote outreach compared with other rural outreach. Of 4,596 specialist doctors, 19% (n = 909) provided outreach; of which, 16% (n = 149) provided remote outreach. Most (75%) outreach providers were metropolitan specialists. In multivariate analysis, outreach was associated with being male (OR 1.38, 1.12 to 1.69), having a rural residence (both inner regional: OR 2.07, 1.68 to 2.54; and outer regional/remote: OR 3.40, 2.38 to 4.87) and working in private consulting rooms (OR 1.24, 1.01 to 1.53). Remote outreach was associated with increasing 5-year age (OR1.17, 1.05 to 1.31) and residing in an outer regional/remote location (OR 10.84, 5.82 to 20.19). Specialists based in inner regional areas were less likely than metropolitan-based specialists to provide remote outreach (OR 0.35, 0.17 to 0.70). There is a healthy level of interest in rural outreach work, but remote outreach is less common. Whilst most providers are metropolitan-based, rural doctors are more

  11. Interaction of biogenic amines with ethanol.

    Ethanol through its primary catabolite, acetaldehyde, competitively inhibits oxidation of aldehyde dehydrogenase substrates. As a consequence biogenic amines form increased quantities of alcohols rather than the corresponding acids. During this biotransformation, condensation reactions between deaminated and intact amines may occur which can yield tetrahydropapaverolines. These compounds are closely related to precursors of opioids which is cause to link ethanol abuse to morphine addiction. There is, however, no pharmacological or clinical evidence suggesting similarities between ethanol dependence or opiod addiction. Acetaldehyde plays an additional role in alkaloidal formation in vitro. Biogenic amines may react with acetaldehyde to form isoquinoline or carboline compounds. Some of these substances have significant pharmacological activity. Furthermore, they may enter neural stores and displace the natural neurotransmitter. Thus, they can act as false neurotransmitters. Some investigators believe that chronic ethanol ingestion leads to significant formation of such aberrant compounds which may then upset autonomic nervous system balance. This disturbance may explain the abnormal sympathetic activity seen in withdrawal. While these ideas about the etiology of alcohol abuse have a definite appeal, they are naturally based on in vitro preliminary work. Much study of the quantitative pharmacology of these compounds in animals is required before judgement can be made as to the merits of the proposed hypotheses. In the meantime, pharmacological studies on the ability of ethanol to depress respiration in the mouse has revealed that unlike opioids or barbituates, respiratory depression induced by ethanol requires the presence in brain of serotonin. This neurotransmitter also mediates the respiratory effects of several other alcohols but curiously, not chloral hydrate, yet this compound is purported to alter biogenic amine metabolism much like ethanol. Thus, the response

    The rapid expansion of ethanol production from sugarcane in Brazil has raised a number of questions regarding its negative consequences and sustainability. Positive impacts are the elimination of lead compounds from gasoline and the reduction of noxious emissions. There is also the reduction of CO 2 emissions, since sugarcane ethanol requires only a small amount of fossil fuels for its production, being thus a renewable fuel. These positive impacts are particularly noticeable in the air quality improvement of metropolitan areas but also in rural areas where mechanized harvesting of green cane is being introduced, eliminating the burning of sugarcane. Negative impacts such as future large-scale ethanol production from sugarcane might lead to the destruction or damage of high-biodiversity areas, deforestation, degradation or damaging of soils through the use of chemicals and soil decarbonization, water resources contamination or depletion, competition between food and fuel production decreasing food security and a worsening of labor conditions on the fields. These questions are discussed here, with the purpose of clarifying the sustainability aspects of ethanol production from sugarcane mainly in Sao Paulo State, where more than 60% of Brazil's sugarcane plantations are located and are responsible for 62% of ethanol production.

    After nearly twenty years since it was first launched, the Brazilian Ethanol Programme to data remains the largest commercial application of biomass for energy production and use in the world. It succeeded in demonstrating the technical feasibility of large scale ethanol production from sugar cane and its use to fuel car engines. On social and economic grounds, however, its evaluation is less positive. The purpose of this study is to provide an updated overview of the perspectives for the Ethanol Programme under the light of increasingly important local and global environmental concerns. Major results show that after oil prices supported upon the basis of its contribution to curb the increase of air pollution in Brazilian cities and of the greenhouse effect. It is concluded that the very survival of the Ethanol Programme, depends upon adequate economic compensation considering its global environmental benefits. These are appraised with two scenarios based on the use of a Markal-like model to define the range and costs of curbing greenhouse gases with a policy aiming at extending the Ethanol Programme

    Influence of blocking of opioid receptors with concomitant intraperitoneal injections of Naloxone (20 mg/kg) (non-selective antagonist of opioid system) on the outcomes of anesthetic dose of ethanol (4,25 ml /kg 25% solution) was investigated in the rats. The sleep-wakefulness cycle (SWC) was used as a model for identification of the effects. Alterations of the SWC structure adequately reflect the neuro-chemical changes, which may develop during pharmacological and non-pharmacological impact. Administration of anesthetic dose of ethanol evoked considerable modification of spontaneous EEG activity of the neocortex. The EEG activity was depressed and full inhibition of spinal reflexes and somatic muscular relaxation did occur. During EEG depression regular SWC did not develop. All phases of SWC were reduced. The disturbances of SWC, such as decrease of slow wave sleep and paradoxical sleep duration and increase of wakefulness, remained for several days. At concomitant administration of Naloxone and ethanol, duration of EEG depression decreased significantly. Generation of normal SWC was observed on the same experimental day. However, it should be noted that complete abolishment of ethanol effects by Naloxone was not observed. The results obtained suggest that Naloxone partially blocks ethanol depressogenic effects and duration of this effect is mediated by GABA-ergic system of the brain.

    Density Functional Theory (DFT: B3LYP/6-31 + G(d)) was used for the optimization of clusters on the potential energy surface of (ethanol)3-water heterotetramers. The tetramerization energies can reach values up to -21.00 kcal/ mol. This energy can not be obtained by just considering the contributions from interactions between two cluster molecules, which suggests of the presence of global cooperative effects (positive). These effects are reflected in smaller hydrogen bond distances and smaller oxygen-oxygen distances, as well as in greater elongations of the O-H proton donor bond with a stronger red-shift in the heterotetramers compared to the ethanol-water heterodimers and the ethanol dimer. The largest cooperativity effect was observed in the four hydrogen bonds arranged in the largest possible cyclic geometric pattern, where all the molecules act as proton acceptor and donor simultaneously. A similar analysis to the characterization of (ethanol)3-water heterotetramers was carried out on (methanol)3-water heterotetramers, and ethanol and methanol tetramers, whose comparison showed a great similarity between all evaluated parameters for the clusters with equal geometric pattern.

    Objective: To present the authors' initial experience of treating auricular arteriovenous malformations(AVMs) with ethanol embolization and to assess the clinical effectiveness of this therapeutic method. Methods: Twenty-two patients with AVMs were enrolled in this study. Through local puncturing or super-selective catheterization the absolute ethanol,or diluted alcohol (based on the pattern of the AVMs), was manually injected into the abnormal vascular plexus of the auricular lesion. The clinical results were estimated with physical examination or angiography at intervals of 3-4 month, and telephone questionnaire was made at monthly intervals for all patients. Results: Thirty-eight ethanol embolization procedures were performed, the amount of ethanol used during the procedure ranged from 4 ml to 65 ml. After the treatment the clinical symptoms were improved, which were manifested as healing of the ulceration, stop of bleeding, disappearing or alleviation of tinnitus. Angiographic examination showed that the abnormal vascular lesion was completely vanished in 9 cases, decreased by 50%-75% in 8 cases and decreased less than 50% in remaining 5 cases. The common complications included irreversible local necrosis and vesiculation. Conclusion: For the treatment of auricular AVMs ethanol embolization is an effective and safe method,which might become the therapy of first choice. (authors)

  19. Prospects for ethanol production from whey

    Marshall, K R

    1978-05-01

    Whey is a by-product of the manufacture of cheese and casein. Casein whey is not as fully utilized as cheese whey although in the last five years commercial processes have been developed to recover the whey proteins, either in denatured form as lactalbumin or in their soluble form as Solac. The removal of the whey proteins makes little difference to the polluting strength or volume of the whey and a crude lactose solution - serum or permeate - remains to be processed. Many processes have been evaluated for the use of this crude lactose solution; one is microbial transformation to produce products such as methane, ethanol, acetone and butanol and etc. The technologies for these processes are well known and it is the economic evaluation which ultimately determines the feasibility of the process being considered. For the purposes of this paper, the prospects for ethanol production have been evaluated. Unless there is a significant reduction in capital costs, it is concluded that ethanol production from whey is not a viable proposition as an energy source for New Zealand. Industrial ethanol (annual imports; 3.5 x 10/sup 6/ 1 CIF value 32 c/1) and potable ethanol production may be worth contemplating.

A cross-sectional, anonymous, self-administered postal survey of registered health promotion volunteers in the Konan area in Shiga Prefecture in Japan, conducted in January 2010. The study sample was 575 registered health promotion volunteers. The survey collected data on health literacy, gender, age, education, self-rated health, perceptions about the volunteer organization, and perceptions of recognition in the community. The level of engagement in health promotion activities was measured by the extent to which the participants engaged in seven healthy behaviors and promoted them to family members and the community. The authors compared the health literacy level and other characteristics of the participants by core health promotion activities, using a chi-squared test, to examine the associations between demographic and other variables and the three core activities (healthy lifestyle, outreach to family, and outreach to community).Logistic regression analysis was conducted to examine the association between the degree to which the volunteers engaged in core activities ("healthy lifestyle," "outreach to family," "outreach to community") and the levels of health literacy (low, medium, high) among health promotion volunteers, controlling for the effects of age, gender, health condition, education which may also have an impact on volunteers' outreach activities. Four hundred and fifty-four questionnaires were returned, a 79.0% response rate. Excluding 16 cases with missing values on health literacy or the degree of health promotion activities, 438 research subjects were included in the analysis (valid response rate: 76.2%).

    Full Text Available Ethanol abuse is linked to several acute and chronic injuries that can lead to health problems. Ethanol addiction is one of the most severe diseases linked to the abuse of this drug. Symptoms of ethanol addiction include compulsive substance intake and withdrawal syndrome. Stress exposure has an important role in addictive behavior for many drugs of abuse (including ethanol, but the consequences of stress and ethanol in the organism when these factors are concomitant results in a complex interaction. We investigated the effects of concomitant, chronic administration of ethanol and stress exposure on the withdrawal and consumption of, as well as the preference for, ethanol in mice. Male Swiss mice (30–35 g, 8-10 per group were exposed to an ethanol liquid diet as the only source of food for 15 days. In the final 5 days, they were exposed to forced swimming stress. Twelve hours after removal of the ethanol liquid diet, animals were evaluated for ethanol withdrawal by measuring anxiety-related behaviors and locomotor activity. Twenty-four hours after evaluation of ethanol withdrawal, they were evaluated for voluntary consumption of ethanol in a “three-bottle choice” paradigm. Mice exposed to chronic consumption of ethanol had decreased locomotor activity during withdrawal. Contrary to our expectations, a concomitant forced swimming stress did not aggravate ethanol withdrawal. Nevertheless, simultaneous ethanol administration and stress exposure increased voluntary consumption of ethanol, mainly solutions containing high concentrations of ethanol. These results showed that stressful situations during ethanol intake may aggravate specific addiction-related behaviors.

    The Ionospheric Radio Science Laboratory (IRSL) at Institute of Space Science, National Central University in Taiwan has been conducting a program for public outreach educations on space science by giving lectures, organizing camps, touring exhibits, and experiencing hand-on experiments to elementary school, high school, and college students as well as general public since 1991. The program began with a topic of traveling/living in space, and was followed by space environment, space mission, and space weather monitoring, etc. and a series of course module and experiment (i.e. experiencing activity) module was carried out. For past decadal, the course modules have been developed to cover the space environment of the Sun, interplanetary space, and geospace, as well as the space technology of the rocket, satellite, space shuttle (plane), space station, living in space, observing the Earth from space, and weather observation. Each course module highlights the current status and latest new finding as well as discusses 1-3 key/core issues/concepts and equip with 2-3 activity/experiment modules to make students more easily to understand the topics/issues. Regarding the space technologies, we focus on remote sensing of Earth's surface by FORMOSAT-2 and occultation sounding by FORMOSAT-3/COSMIC of Taiwan space mission. Moreover, scientific camps are given to lead students a better understanding and interesting on space sciences/ technologies. Currently, a visualized image projecting system, Dagik Earth, is developed to demonstrate the scientific results on a sphere together with the course modules. This system will dramatically improve the educational skill and increase interests of participators.

    Over the last seven years the Astronomy / Astrophysics group in the Department of Physics and Astronomy of Louisiana State University has developed an exten- sive Space Science education and public outreach program. This program includes the local park district (the Recreation and Park Commission for the Parish of East Baton Rouge, BREC), the local amateur astronomer group (the Baton Rouge As- tronomical Society, BRAS), the Louisiana Arts and Science Museum (LASM), and Southern University (SU, part of the largest HBCU system in the nation). Our effort has directly led to the development of the Highland Road Park Observatory (HRPO, http://www.bro.lsu.edu/hrpo) that supports student astronomy training at LSU and SU, amateur observations and a public program for adults and children, establishment of a series of teacher professional development workshops in astronomy and physics, and the "Robots for Internet Experiences (ROBIE)" project (http://www.bro.lsu.edu/) where we have several instruments (e.g. HAM radio, radio telescope, optical tele- scopes) that can be controlled over the internet by students and teachers in the class- room along with associated lessons developed by a teacher group. In addition, this year the LASM, will be opening a new planetarium / space theater in downtown Baton Rouge, Louisiana. We are currently working to bring live views of the heavens from the HRPO telescope to audiences attending planetarium shows and will be working closely with planetarium staff to develop shows that highlight LSU astronomy / space science research. During the presentation we will provide some details about our in- dividual projects, the overall structure of our program, establishing community links and some of the lessons we learned along the way. Finally, we would like to acknowl- edge NASA, Louisiana State University, the Louisiana Systemic Initiatives Program and the Louisiana Technology Innovation Fund for their support.

The poster will share what we have learned about successful partnerships. One portion of the program is focused on providing training and NASA content and resources to K-12 educators. Teacher workshops are performed in several locations per year, including LPI and the Harris County Department of Education, as well as across the country in cooperation with other programs and NASA Planetary Science missions. To serve the public, LPI holds several public events per year called Sky Fest, featuring activities for children, telescopes for night sky viewing, and a short scientist lecture. For Sky Fest, LPI partners with the NASA Johnson Space Center Astronomical Society; they provide the telescopes and interact with members of the public as they are viewing celestial objects. International Observe the Moon Night (InOMN) is held annually and involves the same aspects as Sky Fest, but also includes partners from Johnson Space Center's Astromaterials Research and Exploration Science group, who provide Apollo samples for the event. Another audience that LPI E/PO serves is the NASA Planetary Science E/PO community. Partnering efforts for the E/PO community include providing subject matter experts for professional development workshops and webinars, connections to groups that work with diverse and underserved audiences, and avenues to collaborate with groups such as the National Park Service and the Afterschool Alliance.

    CloudSat Education Network (CEN): Partnerships to improve the understanding of clouds in formal and informal settings. Since The CloudSat satellite launched in 2006 the Formal and Informal education programs for the mission have been focused on bringing an understanding about the mission science and the importance of clouds, climate & weather science. This has been done by creating and strengthening partnership and collaboration within scientific and educational communities around the country and the world. Because CloudSat was formally recognized as a Earth System Science Pathfinder campaign with the GLOBE program, the CEN developed a set of field protocols for student observations that augmented the GLOBE atmosphere protocols when there was a satellite overpass. This shared process between GLOBE & CloudSat resulted in the training & creation of CEN schools that are both GLOBE schools and CloudSat schools, and also produced three GLOBE partnerships that specialize in cloud science education and outreach. In addition, the CEN has developed productive relationships with other NASA missions and EPO teams. Specifically, in collaboration with the NASA CERES mission projects S'Cool and MyNASAData, we have co-presented at NSTA conferences and with schools participating in a NASA EPOESS-funded formal education project. This collaborative work has been a very real benefit to a wide variety of audiences needing to strengthen their understanding of clouds and their roles in the earth system, and we hope will serve as a model to future missions looking to involve the public in mission science.

    Sponsored by the Department of Energy, the ARM Climate Research Facility is a global scientific user facility for the study of climate change. To publicize progress and achievements and to reach new users, the ACRF uses a variety of Web 2.0 tools and strategies that build off of the program’s comprehensive and well established News Center (www.arm.gov/news). These strategies include: an RSS subscription service for specific news categories; an email “newsletter” distribution to the user community that compiles the latest News Center updates into a short summary with links; and a Facebook page that pulls information from the News Center and links to relevant information in other online venues, including those of our collaborators. The ACRF also interacts with users through field campaign blogs, like Discovery Channel’s EarthLive, to share research experiences from the field. Increasingly, field campaign Wikis are established to help ACRF researchers collaborate during the planning and implementation phases of their field studies and include easy to use logs and image libraries to help record the campaigns. This vital reference information is used in developing outreach material that is shared in highlights, news, and Facebook. Other Web 2.0 tools that ACRF uses include Google Maps to help users visualize facility locations and aircraft flight patterns. Easy-to-use comment boxes are also available on many of the data-related web pages on www.arm.gov to encourage feedback. To provide additional opportunities for increased interaction with the public and user community, future Web 2.0 plans under consideration for ACRF include: evaluating field campaigns for Twitter and microblogging opportunities, adding public discussion forums to research highlight web pages, moving existing photos into albums on FlickR or Facebook, and building online video archives through YouTube.

    Podcasts are downloadable web-hosted audio programs (radio on demand). The medium's popularity has grown immensely since its beginning 10+ years ago. "Science and Medicine" remains a prominent category in iTunes (the most popular podcast marketplace), but is unfortunately inundated with non-scientific and dubious content (e.g. the paranormal, health fads, etc.). It seems unlikely that legitimate science content would thrive in such an environment. However, our experience as an independent science podcast shows it is possible to successfully present authentic science to a general audience and maintain popularity. Our show, Science… sort of, began in the fall of 2009, and we have since produced episodes regularly. As of July 31, 2015, our feed hosts 235 episodes, with an average ~6,700 downloads per episode, and over 1.6 million total downloads originating from all across the globe. Thanks to listener involvement and contribution, the show is financially self-sustaining. While production requires a significant time input, no external financial support from the creators or other granting agencies is needed. Traditional media outlets rely on advertisers, thus pressuring shows to produce "popular" content featuring science celebrities. In contrast, independent podcasts can interview big name science communicators, such as Dr. Neil DeGrasse Tyson, while also exploring the research of graduate students and early career scientists. This level playing field provides an unprecedented opportunity for studies to reach a global audience and share research that previously may have only be seen by those at a specialized conference or subscribed to niche journals. Further, direct public engagement helps the audience personally connect to the research and researcher. In combination with other social media platforms, podcasting is a powerful tool in the outreach arsenal, enabling one to share science directly with the world in a way that both educates and excites listeners.

    The WestRock Observatory (WRO), located in Columbus State University's Coca-Cola Space Science Center (CCSSC), is dedicated to education and research in astronomy through hands-on engagement and public participation. The WRO has recently received funding to upgrade the PlaneWave CDK 24-inch Corrected Dall-Kirkham Astrograph telescope. Recent additions to the telescope include an all-new Apogee Alta F16 CCD camera complete with a filter wheel (with narrowband and broadband filters) and a Minor Planet Center Observatory Code (W22). These new upgrades have allowed Astrophysics students to conduct unique research ranging from high precision minor planet astrometry, to broad- and narrow-band imaging of nebulae, to light curve analysis for variable star photometry. These new endeavours, in conjunction with an existing suite of Solar telescopes, gives the WRO the ability to live-stream solar and night-time observing. These streams are available both online and through interactive displays at the CCSSC making the WRO an educational outreach program for a worldwide public audience and a growing astronomical community.Current funding is allowing students to get even more research experience than previously attainable further enabling the expansion of our publicly available gallery of nebula and galaxy images. Support and funding for the acquirement,installation, and upgrading of the new PlaneWave CDK24 has been provided by the International Museum and Library Services via the Museums for America Award Additionally, individual NASA Space Grant Scholarships have helped to secure a number of student interns partially responsible for recent improvements.

    NASA's EPOXI mission is reusing the Deep Impact (DI) flyby spacecraft to study comets and extra-solar planets around other stars. During the Extrasolar Planetary Observations and Characterization (EPOCh) phase of the mission extrasolar planets transiting their parent stars were observed to gain further knowledge and understanding of planetary systems. Observations of Earth also allowed for characterization of Earth as an extrasolar planet. A movie of a lunar transit of the Earth created from EPOCh images and links to existing planet finding activities from other NASA missions are available on the EPOXI website. The Deep Impact Extended Investigation (DIXI) continues the Deep Impact theme of investigating comet properties and formation by observing comet Hartley 2 in November 2010. The EPOXI Education and Public Outreach (E/PO) program is both creating new materials and updating and modifying existing Deep Impact materials based on DI mission results. Comparing Comets is a new educational activity under development that will guide students in conducting analyses of comet surface features similar to those the DIXI scientists will perform after observing comet Hartley 2. A new story designed to stimulate student creativity was developed in alignment with national educational standards. EPOXI E/PO also funded Family Science Night (FSN), a program bringing together students, families, and educators for an evening at the National Air and Space Museum in Washington, DC. FSN events include time for families to explore the museum, a presentation by a space scientist, and an astronomy themed IMAX film. Nine events were held during the 2008-2009 school year with a total attendance of 3,145 (attendance since inception reached 44,732). Half of attendance is reserved for schools with high percentages of underrepresented minorities. EPOXI additionally offers a bi-monthly newsletter to keep the public, teachers, and space enthusiasts updated on current mission activities. For more

    Inspiring youth to pursue the STEM fields is a vital aspect of modern society. Not only does a digital planetarium provide the catalyst to spark the minds of children, but to an assortment of age groups, in a variety of mediums. A digital planetarium is a versatile theatrical environment that can be used for a variety of purposes. The digital planetarium at Glendale Community College is the shining star of the campus. Its ability to satisfy the needs of multiple departments such as, the physical sciences, the biological sciences, the arts, and the foreign languages has become the sharpest tool for public outreach. In this poster we will be discussing the several uses of Glendale Community College’s digital planetarium as well as the programs used to implement them. The central functions of the digital planetarium includes: educational shows, college classes, and entertainment. Educational shows consist of visiting grade school groups, as well as afternoon shows about a specific astronomical topics, which are open to the public. The planetarium is also used to allow Glendale Community College students to see a visual representation of the current curriculum covered in their courses, such as astronomy, organic chemistry, and geology. The true ingenuity and flexibility of the planetarium is the software. Digital Sky allows for the projection of rendered of movies, 3D modeling and student art in the appropriate formats, onto the dome. The digital planetarium is a wonderful tool used to assist, reach out to and display the majesty and complexity of the sciences in an innovative and dynamic method.

    The Falcon Telescope Network (FTN) is a global network of small aperture telescopes developed by the Center for Space Situational Awareness Research in the Department of Physics at the United States Air Force Academy (USAFA). Consisting of commercially available equipment, the FTN is a collaborative effort between USAFA and other educational institutions ranging from two- and four-year colleges to major research universities. USAFA provides the equipment (e.g. telescope, mount, camera, filter wheel, dome, weather station, computers and storage devices) while the educational partners provide the building and infrastructure to support an observatory. The user base includes USAFA along with K-12 and higher education faculty and students. The diversity of the users implies a wide variety of observing interests, and thus the FTN collects images on diverse objects, including satellites, galactic and extragalactic objects, and objects popular for education and public outreach. The raw imagery, all in the public domain, will be accessible to FTN partners and will be archived at USAFA. Currently, there are five Falcon telescopes installed, two in Colorado and one each in Pennsylvania, Chile, and Australia. These five telescopes are in various stages of operational capability but all are remotely operable via a remote desktop application. The FTN team has conducted STEM First Light Projects for three of the U.S. observatories, soliciting proposals from middle and high school students and teachers that suggest and then become what is observed as official STEM first-light objects. Students and teachers learn how to write and submit a proposal as well as how telescopes operate and take data, while university-level students at the U.S. Air Force Academy and The Pennsylvania State University learn how to evaluate proposals and provide feedback to the middle and high school students and teachers. In this paper, we present the current status of the FTN, details of and lessons

    Teaching nano concepts can be a daunting task due to the varying science backgrounds of the audience. Nonetheless, nanoscience education is important as nanotechnology expands. Our perspective is that nano education must be available at earlier stages than what is currently available. Through outreach activities, we examined how high school students and STEM middle/high school teachers approached answering questions about nanomaterials and the environment to design an effective freshman-level college seminar with achievable course goals. Specifically, participants were asked: 1) what color would you expect gold nanoparticles to be; 2) what are ways we can remove nanomaterials from the environment; and 3) what do you expect will happen to nanomaterials when salt is introduced into the system? Initial analysis showed STEM middle and high school teachers and high school students responded similarly. In response to question 1, the majority of the responses suggested color was a function of size. For question 2, both groups suggested the use of filters, magnets or a chemical reaction to remove the nanomaterials. For question 3, both groups expected a chemical reaction to occur. Understanding how foundational high school STEM concepts influenced responses could assist in the curriculum development for an introductory undergraduate nanoscience course. For example, familiar principles of physics and chemistry appeared to direct student responses. From these results, we developed three course goals to test in our college freshman seminar: 1) differentiate between properties of nanomaterials and conventional materials; 2) describe the role of nanomaterials in household items; and 3) form an opinion on the potential impacts of nanoscience and technology on the human health and the environment. Surveys from our first semester showed that the seminar was effective in achieving all course goals for the majority of students.

    The US Ocean Carbon and Biogeochemistry (OCB) Program (www.us-ocb.org) is a dynamic network of scientists working across disciplines to understand the ocean's role in the global carbon cycle and how marine ecosystems and biogeochemical cycles are responding to environmental change. The OCB Project Office, which is based at the Woods Hole Oceanographic Institution (WHOI), serves as a central information hub for this network, bringing different scientific disciplines together and cultivating partnerships with complementary US and international programs to address high-priority research questions. The OCB Project Office plays multiple important support roles, such as hosting and co-sponsoring workshops, short courses, working groups, and synthesis activities on emerging research issues; engaging with relevant national and international science planning initiatives; and developing education and outreach activities and products with the goal of promoting ocean carbon science to broader audiences. Current scientific focus areas of OCB include ocean observations (shipboard, autonomous, satellite, etc.); changing ocean chemistry (acidification, expanding low-oxygen conditions, etc.); ocean carbon uptake and storage; estuarine and coastal carbon cycling; biological pump and associated biological and biogeochemical processes and carbon fluxes; and marine ecosystem response to environmental and evolutionary changes, including physiological and molecular-level responses of individual organisms, as well as shifts in community structure and function. OCB is a bottom-up organization that responds to the continually evolving priorities and needs of its network and engages marine scientists at all career stages. The scientific leadership of OCB includes a scientific steering committee and subcommittees on ocean time-series, ocean acidification, and ocean fertilization. This presentation will highlight recent OCB activities and products of interest to the ocean science community.

    Astronomy on Tap (AoT, astronomyontap.org) is free public outreach event featuring engaging science presentations in bars, often combined with music, games, and prizes, to encourage a fun, interactive atmosphere. AoT events feature several short astronomy-related presentations primarily by local professional scientists, but also by visiting scientists, students, educators, amatuer astronomers, writers, and artists. Events are held in social venues (bars, coffee shops, art galleries, etc.) in order to bring science directly to the public in a relaxed, informal atmosphere. With this we hope to engage a more diverse audience than typical lectures at academic and cultural institutions and to develop enthusiasm for science among voting, tax-paying adults. The flexible format and content of an AoT event is easy to adapt and expand based on the priorities, resources, and interests of local organizers. The social nature of AoT events provides important professional development and networking opportunities in science communication. Since the first New York City event in April 2013, Astronomy on Tap has expanded to more than ten cities globally, including monthly events in NYC, Austin, Seattle, and Tucson; semi-regular events in Columbus, New Haven, Santiago, Toronto, and Denver; occasional (so far) events in Rochester (NY), Baltimore, Lansing, and Washington, DC; and one-off events in Chicago and Taipei. Several venues regularly attract audiences of over 200 people. We have received media coverage online, in print, and occasionally even on radio and television. In this poster we describe the overarching goals and characteristics of AoT events, distinct adaptations of various locations, resources we have developed, and the methods we use to coordinate among the worldwide local organizers.

    Noncommunicable diseases account for 38 million deaths each year, and approximately 75% of these deaths occur in the developing world. The most common causes include cardiovascular diseases, cancer, respiratory diseases, and diabetes mellitus. Many adults with acquired cardiothoracic disease around the world have limited access to health care. In addition, congenital heart disease is present in approximately 1% of live births and is therefore the most common congenital abnormality. More than one million children in the world are born with congenital heart disease each year, and approximately 90% of these children receive suboptimal care or have no access to care. Furthermore, many children affected by noncongenital cardiac conditions also require prevention, diagnosis, and treatment. Medical and surgical volunteerism can help facilitate improvement in cardiothoracic health care in developing countries. As we move into the future, it is essential for physicians and surgeons to be actively involved in political, economic, and social aspects of society to serve health care interests of the underprivileged around the world. Consequently, in developing countries, a critical need exists to establish an increased number of reputable cardiothoracic programs and to enhance many of the programs that already exist. The optimal strategy is usually based on a long-term educational and technical model of support so that as case volumes increase, quality improves and mortality and morbidity decrease. Humanitarian outreach activities should focus on education and sustainability, and surgical tourism should be limited to those countries that will never have the capability to have free-standing cardiothoracic programs.

    At the end of World War II Duane Deming, an internationally known economist enunciated what later came to be called "Total Quality Management" (TQM). The basic thrust of this economic theory called for companies and governments to identify their customers and to do whatever was necessary to meet their demands and to keep them satisfied. It also called for companies to compete internally. That is, they were to build products that competed with their own so that they were always improving. Unfortunately most U.S. corporations failed to heed this advice. Consequently, the Japanese who actively sought Deming's advice and instituted it in their corporate planning, built an economy that outstripped that of the U.S. for the next three to four decades. Only after U.S. corporations reorganized and fashioned joint ventures which incorporated the tenets of TQM with their Japanese competitors did they start to catch up. Other institutions such as the U.S. government and its agencies and schools face the same problem. While the power of the U.S. government is in no danger of being usurped, its agencies and schools face real problems which can be traced back to not heeding Deming's advice. For example, the public schools are facing real pressure from private schools and home school families because they are not meeting the needs of the general public, Likewise, NASA and other government agencies find themselves shortchanged in funding because they have failed to convince the general public that their missions are important. In an attempt to convince the general public that its science mission is both interesting and important, in 1998 the Science Directorate at NASA's Marshall Space Flight Center (MSFC) instituted a new outreach effort using the interact to reach the general public as well as the students. They have called it 'Science@NASA'.
