Energy saving in greenhouses can be obtained by energy balance-controlled screens

Energy Technology Data Exchange (ETDEWEB)

Andersson, N. E. (Univ. of Aarhus, Faculty of Agricultural Sciences, Dept. of Horticulture, Aarslev (Denmark)), e-mail: niels.andersson@agrsci.dk

The energy screens in two greenhouses, one clad with double acrylic and one with single glass, were controlled by an energy balance model. The parameters in the model were heat transmission coefficients, air temperature in the greenhouse and outdoors, irradiance and a single constant for the solar energy efficiency. The energy consumption, screen movements and daily light integral were compared with a glass greenhouse in which the energy screens were controlled by irradiance. In the greenhouse with light-controlled screens the set point for opening and closing of the screens was 5 Wm-2. The energy-saving screens controlled by the energy balance model opened later and closed earlier than in the greenhouse with light-controlled screens. When using the energy balance model the energy saving was 14% for the glass greenhouse and 41% for the double acrylic greenhouse compared with the glass greenhouse with light-controlled screens. The air temperature was on average similar in the three greenhouses, but when the screens were controlled by energy balance the daily light integral was approximately 10% lower and the number of hours the screens were closed was prolonged with 35% for the glass-covered greenhouse and 25% for the double acrylic-covered greenhouse compared with the greenhouse with light-controlled screens. Energy peaks in connection with operation of the screens were not reduced. During the experiment Begonia elatior, Dendranthema grandiflora (Chrysanthemum), Hedera helix, Helianthus annuus, Gerbera jamesonii and Kalanchoe blossfeldiana were grown in the greenhouses. There was a trend in prolongation of the production time when the plants were grown in the glass greenhouse with energy balance control of the screens. A lower number of flowers or inflorescences were observed for some of the plant species produced in the greenhouses with energy balance-controlled screens

Spencer, N J

1993-04-01

Ten years' experience of paediatric outreach clinics is reviewed and evaluated. The advantages and disadvantages of paediatric outreach and its possible place in the new era of contracting and more developed community paediatric services are discussed. It is concluded that paediatric outreach increases parental and professional choice and access to paediatric consultant services, increases service flexibility, reduces unnecessary hospital visits, and enables more rational and relevant clinical decision making. Outreach is particularly relevant in areas of deprivation where paediatric needs are greatest.

Berg, Rick; Booker, Angela; Linde, Charlotte; Preston, Connie

1999-01-01

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.

2003-01-01

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.

Seismology Outreach in Alaska

Science.gov (United States)

Gardine, L.; Tape, C.; West, M. E.

2014-12-01

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.

2017-01-01

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.

Determinants of microfinance outreach in Sub-Saharan Africa: A panel approach

Directory of Open Access Journals (Sweden)

Abdulai Adams

2017-01-01

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.

Residential greenhouse

Energy Technology Data Exchange (ETDEWEB)

1985-02-01

The following report examines the technical and economic viability of residential greenhouse additions in Whitehorse, Yukon. The greenhouse was constructed using the south facing wall of an existing residence as a common wall. Total construction costs were $18,000, including labour. Annual fuel demand for the residence has been reduced by about 10 per cent for an annual saving of $425. In addition, produce to the value of $1,000 is grown annually in the greenhouse for domestic consumption and commercial resale. Typically the greenhouse operates for nine months each year. There is a net thermal loss during the months of November, December and January as a result of the large area of glazing. As well as supplementing the heating supply solar greenhouses can provide additional cash crops which can be used to offset the cost of construction. Humidity problems are minimal and can be dealt with by exhausting high humidity air. One system which has been considered for the greenhouse is to use a standard residential heat pump to remove excess moisture and to pump heat into the house. This would have a secondary benefit of excluding the need to circulate greenhouse air through the house. Thus any allergenic reactions to the greenhouse air would be prevented. 8 refs., 3 figs, 2 tabs.

Dropping Knowledge Like Frozen Pumpkins: Successful Physics Outreach

Science.gov (United States)

Hook, E. A.

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.

2011-11-01

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.

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.

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.

The UMR reactor outreach program for expanded educational utilization

International Nuclear Information System (INIS)

Freeman, D.; Bolon, A.

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

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.

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.

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)

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.

Outcomes for engineering students delivering a STEM education and outreach programme

Fitzallen, Noleine; Brown, Natalie Ruth

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.

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.

A Mobile Nanoscience and Electron Microscopy Outreach Program

Science.gov (United States)

Coffey, Tonya; Kelley, Kyle

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.

Grappling with greenhouse

International Nuclear Information System (INIS)

Mitchell, C.D.

1992-01-01

A natural greenhouse effect keeps the Earth at a temperature suitable for life. Some of the gases responsible for the greenhouse effect are increasing at an unprecedented rate because of human activity. These increased levels of greenhouse gases in the atmosphere will strengthen the natural greenhouse effect, leading to an overall warming of the Earth's surface. Global warming resulting from the enhanced greenhouse effect is likely to be obscured by normal climatic fluctuations for another ten years or more. The extent of human-caused climate change will depend largely on future concentrations of greenhouse gases in the atmosphere. In turn, the composition of the atmosphere depends on the release of greenhouse gases. Releases are hard to predict, because they require an understanding of future human activity. The composition of the atmosphere also depends on the processes which remove greenhouse gases from it. This booklet is summarizing the latest research results in the form of climate change scenarios. The present scenarios of change are based on climate models, together with an understanding of how present-day climate, with its inherent natural variability, affects human activities. These scenarios present a coherent range of future possibilities for climate; they are not predictions but they serve as a useful starting point. It is estimated that human-caused climate change will affect all aspects of life in Australia, including our cities, agriculture, pests and diseases, fisheries and natural ecosystems. 15 figs., ills

2012-01-01

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

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.

The Greenhouse and Anti-Greenhouse Effects on Titan

Science.gov (United States)

McKay, C. P.; Cuzzi, Jeffrey N. (Technical Monitor)

1994-01-01

Titan is the largest moon of Saturn and is the only moon in the solar system with a substantial atmosphere. Its atmosphere is mostly made of nitrogen, with a few percent CH4, 0.1% H2 and an uncertain level of Ar (less than 10%). The surface pressure is 1.5 atms and the surface temperature is 95 K, decreasing to 71 at the tropopause before rising to stratospheric temperatures of 180 K. In pressure and composition Titan's atmosphere is the closest twin to Earth's. The surface of Titan remains unknown, hidden by the thick smog layer, but it may be an ocean of liquid methane and ethane. Titan's atmosphere has a greenhouse effect which is much stronger than the Earth's - 92% of the surface warming is due to greenhouse radiation. However an organic smog layer in the upper atmosphere produces an anti-greenhouse effect that cuts the greenhouse warming in half - removing 35% of the incoming solar radiation. Models suggest that during its formation Titan's atmosphere was heated to high temperatures due to accretional energy. This was followed by a cold Triton-like period which gradually warmed to the present conditions. The coupled greenhouse and haze anti-greenhouse may be relevant to recent suggestions for haze shielding of a CH4 - NH3 early atmosphere on Earth or Mars. When the NASA/ESA mission to the Saturn System, Cassini, launches in a few years it will carry a probe that will be sent to the surface of Titan and show us this world that is strange and yet in many ways similar to our own.

Mid-term evaluation of the Climate Change Action Fund : Public education and outreach (PEO) Block

International Nuclear Information System (INIS)

2001-11-01

In February 1998, the Government of Canada established the Climate Change Action Fund (CCAF) to assist Canada in meeting its commitments under the Kyoto Protocol for the reduction of greenhouse gas emissions. The CCAF managed a budget of 150 million dollars over three years, and the Public Education and Outreach (PEO) Block was allocated 30 million dollars of that total for its operations. Its mandate was to increase public awareness and understanding on the topic of climate change, as well as providing the required information to effect reductions in the emissions of greenhouse gases and adapt to climate change. An evaluation into this program was conducted, and it covered the period September 2000 to January 20, 2001. To date, 152 projects have been approved, which represents an investment of approximately 17.5 million dollars. Approximately 6 million dollars have been spent on the awareness component, while government communication activities used approximately 3.1 million dollars. Staff and project management fees in support of the program account for the remaining funds. This report addressed the performance to date in meeting the objectives, and also included recommendations for improved effectiveness. PEO files and records, a report entitled Interim review of the Climate Change Action Fund PEO Program, interviews with Departmental representatives, and interviews with external stakeholder groups formed the basis for the findings and recommendations. It was determined that future direction represents the most critical issue facing the PEO block. 1 tab

Reasons why specialist doctors undertake rural outreach services: an Australian cross-sectional study.

O'Sullivan, Belinda G; McGrail, Matthew R; Stoelwinder, Johannes U

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.

As scientific scholars and educators we are in a position to make a difference in outreach efforts to elementary and high school students as well as the general public, in addition to mentoring undergraduate and doctoral students. Outreach is a major component of the CAREER grant, the Lederman fellowship, as well as the primary focus of the Young Physicists Outreach Panel (YPOP). As recipients of these awards, and participants in YPOP, we would like to share our insights with the audience. The talk will cover the topics of YPOP, the Lederman Fellowship, and the CAREER grant. The Lederman Fellowship is awarded in recognition of Leon Lederman's legacy as an educator, where the fellows participate in educational/outreach programs of their choice. The NSF makes the CAREER awards to junion faculty. Outreach is of fundamental importance in these grants, with a 40 percent weight attached to the outreach and education component of the proposal. The speakers, a graduate student, a post-doctoral research fellow, and an Assistant Professor, will describe the educational/outreach activities they have been involved in, and discuss how outreach can be integrated into a career in physics research.

Chapter 14. Greenhouses

Energy Technology Data Exchange (ETDEWEB)

Rafferty, Kevin D.

1998-01-01

Greenhouse heating is one of the most common uses of geothermal resources. Because of the significant heating requirements of greenhouses and their ability to use very low- temperature fluids, they are a natural application. The evaluation of a particular greenhouse project involves consideration of the structure heating requirements, and the system to meet those requirements. This chapter is intended to provide information on each of these areas.

O'Sullivan, Belinda G; Joyce, Catherine M; McGrail, Matthew R

2014-09-04

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

Greenhouse Gas Abatement with Distributed Generation in California's Commercial Buildings

International Nuclear Information System (INIS)

Stadler, Michael; Marnay, Chris; Cardoso, Goncalo; Megel, Olivier; Siddiqui, Afzal; Lai, Judy

2009-01-01

Lawrence Berkeley National Laboratory (LBL) is working with the California Energy Commission (CEC) to determine the role of distributed generation (DG) in greenhouse gas reductions. The impact of DG on large industrial sites is well known, and mostly, the potentials are already harvested. In contrast, little is known about the impact of DG on commercial buildings with peak electric loads ranging from 100 kW to 5 MW. We examine how DG with combined heat and power (CHP) may be implemented within the context of a cost minimizing microgrid that is able to adopt and operate various smart energy technologies, such as thermal and photovoltaic (PV) on-site generation, heat exchangers, solar thermal collectors, absorption chillers, and storage systems. We use a mixed-integer linear program (MILP) that has the minimization of a site's annual energy costs as objective. Using 138 representative commercial sites in California (CA) with existing tariff rates and technology data, we find the greenhouse gas reduction potential for California's commercial sector. This paper shows results from the ongoing research project and finished work from a two year U.S. Department of Energy research project. To show the impact of the different technologies on CO2 emissions, several sensitivity runs for different climate zones within CA with different technology performance expectations for 2020 were performed. The considered sites can contribute between 1 Mt/a and 1.8 Mt/a to the California Air Resources Board (CARB) goal of 6.7Mt/a CO2 abatement potential in 2020. Also, with lower PV and storage costs as well as consideration of a CO2 pricing scheme, our results indicate that PV and electric storage adoption can compete rather than supplement each other when the tariff structure and costs of electricity supply have been taken into consideration. To satisfy the site's objective of minimizing energy costs, the batteries will be charged also by CHP systems during off-peak and mid-peak hours and

The International Heliophysical Year Education and Outreach Program

Rabello-Soares, M.; Morrow, C.; Thompson, B.

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. ~

One World, One Sky: Outreach in a Multicultural, Multilingual Metropolis

Science.gov (United States)

Reid, M.

2015-03-01

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.

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

Science.gov (United States)

O'Sullivan, Belinda G; McGrail, Matthew R; Stoelwinder, Johannes U

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

Kendall, Jason S.

2013-01-01

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.

Potential for greenhouse gas emission reductions using surplus electricity in hydrogen, methane and methanol production via electrolysis

International Nuclear Information System (INIS)

Uusitalo, Ville; Väisänen, Sanni; Inkeri, Eero; Soukka, Risto

2017-01-01

Highlights: • Greenhouse gas emission reductions using power-to-x processes are studied using life cycle assessment. • Surplus electricity use led to greenhouse gas emission reductions in all studied cases. • Highest reductions can be achieved by using hydrogen to replace fossil based hydrogen. • High reductions are also achieved when fossil transportation fuels are replaced. - Abstract: Using a life cycle perspective, potentials for greenhouse gas emission reductions using various power-to-x processes via electrolysis have been compared. Because of increasing renewable electricity production, occasionally surplus renewable electricity is produced, which leads to situations where the price of electricity approach zero. This surplus electricity can be used in hydrogen, methane and methanol production via electrolysis and other additional processes. Life cycle assessments have been utilized to compare these options in terms of greenhouse gas emission reductions. All of the power-to-x options studied lead to greenhouse gas emission reductions as compared to conventional production processes based on fossil fuels. The highest greenhouse gas emission reductions can be gained when hydrogen from steam reforming is replaced by hydrogen from the power-to-x process. High greenhouse gas emission reductions can also be achieved when power-to-x products are utilized as an energy source for transportation, replacing fossil transportation fuels. A third option with high greenhouse gas emission reduction potential is methane production, storing and electricity conversion in gas engines during peak consumption hours. It is concluded that the power-to-x processes provide a good potential solution for reducing greenhouse gas emissions in various sectors.

The emergence of ethical issues in the provision of online sexual health outreach for gay, bisexual, two-spirit and other men who have sex with men: perspectives of online outreach workers.

Science.gov (United States)

Fantus, Sophia; Souleymanov, Rusty; Lachowsky, Nathan J; Brennan, David J

2017-11-03

Mobile applications and socio-sexual networking websites are used by outreach workers to respond synchronously to questions and provide information, resources, and referrals on sexual health and STI/HIV prevention, testing, and care to gay, bisexual and other men who have sex with men (GB2M). This exploratory study examined ethical issues identified by online outreach workers who conduct online sexual health outreach for GB2M. Semi-structured individual interviews were conducted between November 2013 and April 2014 with online providers and managers (n = 22) to explore the benefits, challenges, and ethical implications of delivering online outreach services in Ontario, Canada. Interviews were digitally recorded and transcribed verbatim. Thematic analyses were conducted, and member-checking, analyses by multiple coders, and peer debriefing supported validity and reliability. Four themes emerged on the ethical queries of providing online sexual health outreach for GB2M: (a) managing personal and professional boundaries with clients; (b) disclosing personal or identifiable information to clients; (c) maintaining client confidentiality and anonymity; and (d) security and data storage measures of online information. Participants illustrated familiarity with potential ethical challenges, and discussed ways in which they seek to mitigate and prevent ethical conflict. Implications of this analysis for outreach workers, researchers, bioethicists, and policy-makers are to: (1) understand ethical complexities associated with online HIV prevention and outreach for GB2M; (2) foster dialogue to recognize and address potential ethical conflict; and (3) identify competencies and skills to mitigate risk and promote responsive and accessible online HIV outreach.

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.

Outreach to Inspire Girls in Geology: A Recipe for Success (Invited)

Science.gov (United States)

Kekelis, L.

2010-12-01

Geology and engineering careers can seem very abstract to a young girl, especially to a girl who has no role model in technical fields. Many girls want to make the world a better place but don’t see how their interests connect with geology or engineering. Role models and field trips to worksites are instrumental in encouraging girls to consider careers in geoscience and engineering. The opportunities to see real-world applications of technology and meet with role models who work in technical fields are extremely impactful and can have a strong influence on a girl’s career path. Together we need to do a better job of communicating what geoscience and engineering have to offer girls and what girls have to offer these fields. This presentation will provide practical tips to help combat stereotypes, 2) share resources for outreach at one-day special events, summer camps, visits to the classroom and field trips to corporate sites and college campuses, and 3) highlight strategies for groups to work collaboratively in outreach. This presentation will help those currently involved in outreach who want to improve on existing efforts, along with those who have never done outreach and are interested in getting started. Techbridge will share a “recipe for success” for planning and hosting role model visits to the classroom and field trips. A case study of outreach by Chevron with Techbridge girls will be shared including the pre-event planning that made this event a success. Activities that make geology fun and friendly to girls and tips for dispelling stereotypes about careers in geology and engineering will also be shared. Participants will be invited to ask questions and share on topics of interest, such as “Challenges with outreach,” “How to get involved without burning out,” and “How to show your manager or organization that outreach is worth the effort.” We will also promote a candid discussion of the challenges that can arise along with way and how

The authors discuss the impact of an increasing greenhouse effect on three aspects of regional climate: droughts, storms and temperature. A continuous of current growth rates of greenhouse gases causes an increase in the frequency and severity of droughts in their climate model simulations, with the greatest impacts in broad regions of the subtropics and middle latitudes. But the greenhouse effect enhances both ends of the hydrologic cycle in the model, that is, there is an increased frequency of extreme wet situations, as well as increased drought. Model results are shown to imply that increased greenhouse warming will lead to more intense thunderstorms, that is, deeper thunderstorms with greater rainfall. Emanual has shown that the model results also imply that the greenhouse warming leads to more destructive tropical cyclones. The authors present updated records of observed temperatures and show that the observations and model results, averaged over the globe and over the US, are generally consistent. The impacts of simulated climate changes on droughts, storms and temperature provide no evidence that there will be regional winners if greenhouse gases continue to increase rapidly

A Pilot Astronomy Outreach Project in Bangladesh

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

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

Science.gov (United States)

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.

2015-01-01

Losing the Dark is a PSA video available for public outreach through fulldome theaters as well as conventional venues (classroom, lecture hall, YouTube, Vimeo). It was created by Loch Ness Productions for the International Dark Sky Association. It explains problems caused by light pollution, which targets astronomy, health, and the environment. Losing the Dark also suggests ways people can implement "wise lighting" practices to help mitigate light pollution. The video is available free of charge for outreach professionals in planetarium facilities (both fulldome and classical), science centers, classroom, and other outreach venues, and has been translated into 13 languages. It is available via download, USB key (at cost), and through online venues. This paper summarizes the program's outreach to more than a thousand fulldome theaters, nearly 100,000 views via four sites on Youtube and Vimeo,a number of presentations at other museum and classroom facilities, and shares some preliminary metrics and commentary from users.

The greenhouse effect on earth can be defined as the long wave energy trapped in the atmosphere. Climate forcing and climate system response within which climate feedback mechanisms are contained are determined. Quantitative examples illustrate what could happen if the greenhouse effect is perturbed by human activities, in particular if CO2 atmospheric concentration would double in the future. Recent satellite measurements of the greenhouse effect are given. The net cooling effect of clouds and whether or not there will be less cooling by clouds as the planet warms are also discussed

Teaching About the Links Between Soils and Climate: An International Year of Soil Outreach by the Soil Science Society of America

Brevik, Eric C.

2015-04-01

Soil scientists are well aware of the intimate links that exist between soils and climate, but the same is not always true of the broader population. In an attempt to help address this, the Soil Science Society of America (SSSA) has designated the theme "Soils and Climate" for the month of November, 2015 as part of the SSSA International Year of Soil (IYS) celebration. The topic has been further subdivided into three subthemes: 1) carbon sequestration and greenhouse gases, 2) Soils and past environments, and 3) Desertification and drought. Each subtheme outreach has two parts 1) lesson plans that K-12 educators can use in their classrooms, and 2) materials that a trained soil scientist can present to the general public. Activities developed for the theme include classroom activities to accompany an online game that students can play to see how farm management choices influence greenhouse gas emissions, questions to go with a vermicomposting activity, and discussion session questions to go with a movie on the USA Dust Bowl. All materials are available online free of charge. The Soils and Climate materials can be found at https://www.soils.org/iys/12-month-resources/november; all of the SSSA IYS materials can be found at https://www.soils.org/iys.

PROFESSIONALS BACK TO SCHOOL - AN ENGINEERING OUTREACH PROGRAMME: A CASE STUDY IN MALAYSIA

Directory of Open Access Journals (Sweden)

BALAMURALITHARA BALAKRISHNAN

2017-10-01

Full Text Available The introduction of engineering education in K-12 classrooms opens up a number of opportunities for STEM learning to support the acquisition of knowledge and skills related to science and mathematics subjects. Several initiatives, including outreach programmes, have been carried out to promote engineering subjects and professions. To supplement the existing Malaysian curricula, an outreach programme seems a viable solution to help improve the understanding and awareness of the importance of engineering among students. In this regard, an engineering outreach program called Professionals Back to School was carried out involving a group of 40 students with the participation of several engineering practitioners. Later all the participants were interviewed to elicit feedback on the programme. The findings of the interview showed that all the participants agreed that the outreach programme was beneficial, and a majority found it to be motivational. Given these positive findings, engineering outreach programmes are highly recommended to Malaysian secondary schools to help create interest among schoolchildren in STEM education and professions.

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

[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.

In a continuing effort to invite new and larger segments of the public to participate in Yucca Mountain Site Characterization Project (YMP) Public Outreach Programs, examination of methods to enhance existing Public Outreach advertising programs began in 1993. Apart from the desire to promote greater public awareness and participation of the YMP, the Project itself is receiving less coverage of its scientific aspects in the local media. Since the public is already comfortable receiving messages in these media, this becomes an additional reason to explore and study advertising as a platform for invitations to the public

2006-03-01

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

``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

Ozone: The secret greenhouse gas

The atmospheric ozone not only protects against harmful ultraviolet radiation; it also contributes to the greenhouse effect. Ozone is one of the jokers to make it difficult to calculate the climatic effect of anthropogenic emissions. The greenhouse effect and the ozone layer should not be confused. The greenhouse effect creates problems when it becomes enhanced, so that the earth becomes warmer. The problem with the ozone layer, on the contrary, is that it becomes thinner and so more of the harmful ultraviolet radiation gets through to the earth. However, ozone is also a greenhouse gas and so the greenhouse effect and the ozone layer are connected

Respiratory diseases are a leading cause of morbidity and mortality in Indigenous Australians. However, there are limited approaches to specialist respiratory care in rural and remote communities that are culturally appropriate. A specialist Indigenous Respiratory Outreach Care (IROC) program, developed to address this gap, is described. The aim of the present study was to implement, pilot and evaluate multidisciplinary specialist respiratory outreach medical teams in rural and remote Indigenous communities in Queensland, Australia. Sites were identified based on a perception of unmet need, burden of respiratory disease and/or capacity to use the clinical service and capacity building for support offered. IROC commenced in March 2011 and, to date, has been implemented in 13 communities servicing a population of approximately 43000 Indigenous people. Clinical service delivery has been possible through community engagement and capacity building initiatives directed by community protocols. IROC is a culturally sensitive and sustainable model for adult and paediatric specialist outreach respiratory services that may be transferrable to Indigenous communities across Queensland and Australia.

We describe the effectiveness of community outreach and engagement in supporting recruitment for the US National Children's Vanguard Study between 2009 and 2012. Thirty-seven study locations used 1 of 4 strategies to recruit 18-49-year-old pregnant or trying to conceive women: (1) Initial Vanguard Study used household-based recruitment; (2) Direct Outreach emphasized self-referral; (3) Enhanced Household-Based Recruitment enhanced Initial Vanguard Study strategies; and (4) Provider-Based Recruitment recruited through healthcare providers. Outreach and engagement included advance letters, interactions with healthcare providers, participation in community events, contacts with community organizations, and media outreach. After 1-2 years, 41%-74% of 9844 study-eligible women had heard about the National Children's Vanguard Study when first approached. Women who heard were 1.5-3 times more likely to consent. Hearing via word-of-mouth or the media most frequently predicted consent. The more sources women heard from the higher the odds of consent. We conclude that tailored outreach and engagement facilitate recruitment in cohort studies.

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.

EPA's landfill methane outreach program: demonstration of the new E-PLUS economic evaluation model: future trends and activities

International Nuclear Information System (INIS)

Kerr, T.; Paleyanda, P.; Forbes, C.D.

1997-01-01

Landfills contain most of the municipal solid waste (MSW) generated in the United States. As this landfilled MSW decomposes, it produces landfill gas (LFG), containing approximately 50% methane, 43-47% carbon dioxide, and 3-7% non-methane organic compounds (NMOCs). Federal regulations require affected landfills to collect and combust their LFG emissions in order to destroy NMOCs, as they are important precursors to local smog. Since 1994, the U.S. Environmental Protection Agency's Landfill Methane Outreach Program (LMOP) has been working to promote LFG-to-energy as a cost-effective way to reduce emissions of methane - a potent greenhouse gas. The LMOP's latest tool is ''E-PLUS'', Windows-compatible software that can be used to screen potential LFG-to-energy projects. E-PLUS, the Energy Project Landfill Gas Utilization Software, is capable of evaluating the economic feasibility of two energy recovery technologies based on potential LFG emissions estimates. This paper provides an overview of E-PLUS and describes its features and functions in detail. (author)

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.

Public engagement and outreach activities are increasingly using specialist staff for co-ordination, training and support for researchers, they are also becoming expected for large investments. Here, the experience of public engagement and outreach a large, interdisciplinary Research Hub is described. dot.rural, based at the University of Aberdeen UK, is a £11.8 million Research Councils UK Rural Digital Economy Hub, funded as part of the RCUK Digital Economy Theme (2009-2015). Digital Economy research aims to realise the transformational impact of digital technologies on aspects of the environment, community life, cultural experiences, future society, and the economy. The dot.rural Hub involves 92 researchers from 12 different disciplines, including Geography, Hydrology and Ecology.

OUTREACH

CERN Multimedia

David Barney

The highlight for CMS Outreach during the past few months was of course the CERN Open Days on 5th and 6th April. Of the 73000 people who came to CERN during that weekend more than 10000 visited CMS in the cavern, thanks to an incredible logistical effort from many members of CMS. The underground visit was only one of several activites at point 5. Others included a picture gallery (with huge thanks to Michael Hoch), an artwork corner for children, a working spark chamber and regular demonstrations of cryogenics (many thanks to Goran Perinic) and photogrammetry (thanks to Christian Lasseur et al). There were also well-attended public presentations on Particle Physics, CERN and CMS as well as a visit of "Fred" from the popular French television show "C'est pas Sorcier". A souvenir kiosk was also a popular attraction, selling CMS tee-shirts, polo-shirts, baseball caps and keyrings, amongst other items. These things are available to purchase from the CMS Secretariat in build...

Full Text Available Use of renewable energy resources should be brought forward to reduce heating costs of greenhouses and to minimize the use of ever-depleting fossil fuels. Geothermal energy not only provides the heat required throughout plant growth, but also allow a year-long production. Geothermal resources with several other benefits therefore play significant role in agricultural activities. With regard to geothermal potential and implementation, Turkey has the 7th place in the world and the 1st place in Europe. Majority of country geothermal resources is used in greenhouse heating. The size of geothermal greenhouses increased 5 folds during the last decade and reached to 2500 decare. In this study, current status of geothermal greenhousing of Turkey was presented; problems and possible solutions were discussed.

EarthScope Education and Outreach: Accomplishments and Emerging Opportunities

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

Greenhouse gases and global warming

International Nuclear Information System (INIS)

1995-01-01

From previous articles we have learned about the complexities of our environment, its atmosphere and its climate system. we have also learned that climate change and, therefore global warm and cool periods are naturally occurring phenomena. Moreover, all scientific evidence suggests that global warming, are likely to occur again naturally in the future. However, we have not yet considered the role of the rates of climate change in affecting the biosphere. It appears that how quickly the climate changes may be more important than the change itself. In light of this concern, let us now consider the possibility that, is due to human activity. We may over the next century experience global warming at rates and magnitudes unparalleled in recent geologic history. The following questions are answered; What can we learn from past climates? What do we know about global climates over the past 100 years? What causes temperature change? What are the greenhouse gases? How much have concentration of greenhouse gases increased in recent years? Why are increases in concentrations of greenhouse of concern? What is the e nhanced greenhouse effect ? How can human activity impact the global climate? What are some reasons for increased concentrations of greenhouse gases? What are fossil fuel and how do they transform into greenhouse gases? Who are the biggest emitters of greenhouse gases? Why are canada per capita emissions of greenhouse gases relatively high? (Author)

The Peculiar Negative Greenhouse Effect Over Antarctica

Sejas, S.; Taylor, P. C.; Cai, M.

2017-12-01

Greenhouse gases warm the climate system by reducing the energy loss to space through the greenhouse effect. Thus, a common way to measure the strength of the greenhouse effect is by taking the difference between the surface longwave (LW) emission and the outgoing LW radiation. Based on this definition, a paradoxical negative greenhouse effect is found over the Antarctic Plateau, which suprisingly indicates that greenhouse gases enhance energy loss to space. Using 13 years of NASA satellite observations, we verify the existence of the negative greenhouse effect and find that the magnitude and sign of the greenhouse effect varies seasonally and spectrally. A previous explanation attributes the negative greenhouse effect solely to stratospheric CO2 and warmer than surface stratospheric temperatures. However, we surprisingly find that the negative greenhouse effect is predominantly caused by tropospheric water vapor. A novel principle-based explanation provides the first complete account of the Antarctic Plateau's negative greenhouse effect indicating that it is controlled by the vertical variation of temperature and greenhouse gas absorption strength. Our findings indicate that the strong surface-based temperature inversion and scarcity of free tropospheric water vapor over the Antarctic Plateau cause the negative greenhouse effect. These are climatological features uniquely found in the Antarctic Plateau region, explaining why the greenhouse effect is positive everywhere else.

A 5-year retrospective audit of prescribing by a critical care outreach team.

UK prescribing legislation changes made in 2006 and 2012 enabled appropriately qualified nurses to prescribe any licensed medication, and all controlled drugs in schedule 2-5 of the Misuse of Drugs Regulations 2001, for any medical condition within their clinical competence. Critical Care Outreach nurses who are independent nurse prescribers are ideally placed to ensure that acutely ill patients receive treatment without delay. The perceived challenge was how Critical Care Outreach nurses would be able to safely prescribe for a diverse patient group. This study informs this developing area of nurse prescribing in critical care practice. The aims of the audit were to: identify which medications were prescribed; develop a critical care outreach formulary; identify the frequency, timing and number of prescribing decisions being made; identify if prescribing practice changed over the years and provide information for our continuing professional development. This article reports on data collected from a 5-year retrospective audit; of prescribing activity undertaken by nine independent nurse prescribers working in a 24/7 Critical Care Outreach team of a 600-bedded district general hospital in the UK. In total, 8216 medication items were prescribed, with an average of 2·6 prescribed per shift. The most commonly prescribed items were intravenous fluids and analgesia, which were mostly prescribed at night and weekends. The audit has shown that Critical Care Outreach nurse prescribing is feasible in a whole hospital patient population. The majority of prescribing occurred after 16:00 and at night. Further research would be beneficial, particularly looking at patient outcomes following reviews from prescribing critical care outreach nurses. The audit is one of the only long-term studies that describes prescribing practice in Critical Care Outreach teams in the UK. © 2017 British Association of Critical Care Nurses.

Through the greenhouse window

International Nuclear Information System (INIS)

Townsley, M.

1989-01-01

Nuclear power is being promoted as the only answer to the greenhouse effect. However, power station emissions (from fossil-fuel powered stations) account for only a fraction of the total carbon dioxide emissions. And carbon dioxide accounts for only about a half of the global warming effect -the other gases which create the greenhouse effect must also be limited. Nuclear energy is neither a practical nor economic alternative. Energy efficiency and conservation is a far better answer to the greenhouse effect. (U.K.)

Greenhouse effect: Myth or reality

This paper debates on greenhouse effect controversy. Natural greenhouse effect is beneficent but additional greenhouse effect, in relation with human activities, can present a major risk for humanity. However an international agreement is difficult owing to the enormous costs which could not be endured by South economies. A tax on carbon dioxide emissions would have for consequence a wave of industrial delocalizations without precedent with important unemployment in Europe and no impact on additional greenhouse effect because it is a radiative effect and it is not a classic local chemical pollution. 11 refs., 10 figs

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.

Human migration, protected areas, and conservation outreach in Tanzania.

Science.gov (United States)

Salerno, Jonathan D; Borgerhoff Mulder, Monique; Kefauver, Shawn C

2014-06-01

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.

Buying greenhouse insurance

International Nuclear Information System (INIS)

Manne, A.S.; Richels, R.G.

1992-01-01

A growing concern that the increasing accumulation of greenhouse gases will lead to undesirable changes in global climate has resulted in proposals, both in the United States and internationally, to set physical targets for reducing greenhouse gas emissions. But what will these proposals cost? This book outlines a way to think about greenhouse-effect decisions under uncertainty. It describes an insightful model for determining the economic costs of limiting CO 2 emissions produced by burning fossil fuels and provides a solid analytical base for rethinking public policy on the far-reaching issue of global warming. It presents region-by-region estimates of the costs that would underlie an international agreement. Using a computer model known as Global 2100, they analyze the economic impacts of limiting CO 2 emissions under alternative supply and conservation scenarios. The results clearly indicate that a reduction in emissions is not the sole policy response to potential climate change. Following a summary of the greenhouse effect, its likely causes, and possible consequences, this book takes up issues that concern the public at large. They provide an overview of Global 2100, look at how the U.S. energy sector is likely to evolve under business-as-usual conditions and under carbon constraints, and describe the concept of greenhouse insurance. They consider possible global agreements, including an estimate of benefits that might result from trading in an international market in emission rights. They conclude with a technical description directed toward modeling specialists

Automated Signal Processing Applied to Volatile-Based Inspection of Greenhouse Crops

Science.gov (United States)

Jansen, Roel; Hofstee, Jan Willem; Bouwmeester, Harro; van Henten, Eldert

2010-01-01

Gas chromatograph–mass spectrometers (GC-MS) have been used and shown utility for volatile-based inspection of greenhouse crops. However, a widely recognized difficulty associated with GC-MS application is the large and complex data generated by this instrument. As a consequence, experienced analysts are often required to process this data in order to determine the concentrations of the volatile organic compounds (VOCs) of interest. Manual processing is time-consuming, labour intensive and may be subject to errors due to fatigue. The objective of this study was to assess whether or not GC-MS data can also be automatically processed in order to determine the concentrations of crop health associated VOCs in a greenhouse. An experimental dataset that consisted of twelve data files was processed both manually and automatically to address this question. Manual processing was based on simple peak integration while the automatic processing relied on the algorithms implemented in the MetAlign™ software package. The results of automatic processing of the experimental dataset resulted in concentrations similar to that after manual processing. These results demonstrate that GC-MS data can be automatically processed in order to accurately determine the concentrations of crop health associated VOCs in a greenhouse. When processing GC-MS data automatically, noise reduction, alignment, baseline correction and normalisation are required. PMID:22163594

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.

Astronomy Outreach Activites through the University of California, Irvine

Thornton, Carol E.; Smecker-Hane, T.

2006-06-01

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.

Amphibious Encounters: Coral and People in Conservation Outreach in Indonesia

Directory of Open Access Journals (Sweden)

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.

Creswell, Paul D; Vogt, Christy M; Wozniak, Ryan J; Camponeschi, Jenny; Werner, Mark A; Meiman, Jonathan G

In December 2014, the largest carbon monoxide (CO) poisoning in Wisconsin's history occurred at an ice arena. Following this event, the Wisconsin Environmental Public Health Tracking (WI EPHT) Program sought to improve outreach and surveillance efforts. WI EPHT designed and distributed educational materials on CO poisoning prevention and surveyed stakeholders to gauge the effectiveness of outreach efforts. To enhance surveillance, WI EPHT utilized data from the Wisconsin Poison Center (WPC) to generate real-time alerts of anomalous numbers of CO-related calls. WI EPHT found that 42% of stakeholders reviewed the outreach materials, and 1 ice arena had installed a CO detector as a result. CO alerts were developed using WPC data and are now routinely used in statewide public health surveillance. WI EPHT staff improved CO poisoning prevention outreach and saw a positive response among stakeholders. This work demonstrates ways that health agencies can improve outreach and surveillance for CO poisoning. Improvements in these areas can bolster public health response and may prevent CO-related illness and injury.

Changing communities, changing spaces: the challenges of health promotion outreach in cyberspace.

Science.gov (United States)

Hallett, Jonathan; Brown, Graham; Maycock, Bruce; Langdon, Patricia

2007-01-01

This article is a case study of an Internet chat room outreach project in Perth, Western Australia. The CyberReach project sought to adapt current peer based health promotion outreach, training and supervision frameworks to an online outreach setting in a way that was effective and supported by the online community. It targeted marginalised groups to trial the provision of online mental and sexual health promotion incorporating a participatory action research model into its development and implementation. Three 6-week trial periods were conducted and significant changes were made in response to changes in the online environment and to improve sustainability and effectiveness of the protocols. Four themes arose from CyberReach's experience: online group processes are unique due to the creation of extensive personal networks and occurrence of disclosure without face-to-face contact across potentially large geographic barriers; flexibility is required to adapt to technological changes and online community flux; enforcing boundaries and delineating peer education from therapeutic support can be challenging when only using text-based communication; and Internet outreach can be time intensive with small returns in actual community engagement and constant technological up-skilling of staff may be required. Based on the project's experiences we offer the following recommendations when planning similar Internet outreach strategies: Funding and planning groups need to be aware that the Internet environment is constantly changing and planning and funding arrangements need to reflect a capacity to remain flexible; Programs need to be firmly connected to the communities they are outreaching therefore a peer-based education component is strongly encouraged; Careful consideration should be taken regarding data collection so that the environment and the individuals within are respected; Further research needs to be conducted to understand the styles and approaches of different

An outreach activity is two-way communication for communicating information. The public outreach activities of USA and Japan for increasing mutual understanding of nuclear energy, and the effective outreach activities are stated. On USA, many communicators in the member of ANS (American Nuclear Society) play an active part in the outreach activities for the policy makers, educators, students, and stakeholders. NEI (Nuclear Energy Institute, USA) provides people with useful information such as benefits and safety control system of nuclear energy, and it has carried out an attitude survey. FPL (Florida Power and Light Company) selected the communicators by ten evaluation items and they made a group and a clear grasp of the goal, needs, and plans and then communicated residents, and sent out questionnaires. Some examples of the special education program for training the communicators in USA are described. In Japan, JAEA gave lessons of nuclear energy, radiation and disaster prevention at the primary, junior high and high schools, friendly talks with local residents, preparing the teaching materials with residents and training of communicators.

To explore the association between health literacy and levels of three types of core activities among health promotion volunteers (developing a healthy lifestyle, outreach to family, and outreach to community members). 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%). Health literacy and a few demographic and other characteristics of the volunteers were associated with the three core health

Objectives To explore the association between health literacy and levels of three types of core activities among health promotion volunteers (developing a healthy lifestyle, outreach to family, and outreach to community members). Study Design 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. Methods 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. Results 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%).

In this paper the influence of greenhouse construction on energy efficiency in winter lettuce production was estimated for four different double plastic covered greenhouses in Serbia region. Plastic coverings were introduced in this region as a mean of making the plant production more energy efficient. Additionally, as a means of lowering energy consumption, tunnel structures were proposed. In order to see whether the greenhouse structure influences energy consumption, four different double plastic covered greenhouses. Two tunnel types, 9 x 58 m and 8 x 25 m, one gutter-connected structure and multi-span plastic covered greenhouse. The gutter-connected structure was 2 x 7 m wide and 39 m long while the multi-span structure was 20 x 6.4 m wide and 42 m long. On the basis of lettuce production output and the energy input, specific energy input, energy output-input ratio and energy productivity were estimated. Results show that the lowest energy consumption was obtained for multi-span greenhouse, 9.76 MJ/m{sup 2}. The highest energy consumption was obtained in tunnel, 9 x 58 m, 13.93 MJ/m{sup 2}. The highest value for output-input ratio was calculated for multi-span greenhouse (0.29), followed by gutter-connected greenhouse (0.21), tunnel 9 x 58 m (0.17) and tunnel, 8 x 25 m (0.15). Results also show that energy productivity can be higher if multi-span greenhouse structures are used. (author)

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.

Inside Story of Gas Processes within Stormwater Biofilters: Does Greenhouse Gas Production Tarnish the Benefits of Nitrogen Removal?

Stormwater biofilters are dynamic environments, supporting diverse processes that act to capture and transform incoming pollutants. However, beneficial water treatment processes can be accompanied by undesirable greenhouse gas production. This study investigated the potential for nitrous oxide (N 2 O) and methane (CH 4 ) generation in dissolved form at the base of laboratory-scale stormwater biofilter columns. The influence of plant presence, species, inflow frequency, and inclusion of a saturated zone and carbon source were studied. Free-draining biofilters remained aerobic with negligible greenhouse gas production during storm events. Designs with a saturated zone were oxygenated at their base by incoming stormwater before anaerobic conditions rapidly re-established, although extended dry periods allowed the reintroduction of oxygen by evapotranspiration. Production of CH 4 and N 2 O in the saturated zone varied significantly in response to plant presence, species, and wetting and drying. Concentrations of N 2 O typically peaked rapidly following stormwater inundation, associated with limited plant root systems and poorer nitrogen removal from biofilter effluent. Production of CH 4 also commenced quickly but continued throughout the anaerobic interevent period and lacked clear relationships with plant characteristics or nitrogen removal performance. Dissolved greenhouse gas concentrations were highly variable, but peak concentrations of N 2 O accounted for nitrogen load. While further work is required to measure surface emissions, the potential for substantial release of N 2 O or CH 4 in biofilter effluent appears relatively low.

Reaching for the Stars in your Golden Years: The Importance of Outreach for Senior Citizens

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.

Empirical links between the local runaway greenhouse, super-greenhouse, and deep convection in Earth's tropics

Science.gov (United States)

Dewey, M. C.; Goldblatt, C.

2017-12-01

Energy balance requires that energy absorbed and emitted at the top of the atmosphere equal; this is maintained via the Planck feedback whereby outgoing longwave radiation (OLR) increases as surface temperature increases. There are two cases where this breaks down: the runaway greenhouse (known from planetary sciences theory) characterized by an asymptotic limit on OLR from moist atmospheres, and the super-greenhouse (known from tropical meteorology observations) where OLR decreases with surface temperature when the atmosphere is moist aloft. Here we show that the runaway greenhouse limit can be empirically observed and constrained in Earth's tropics, that the runaway and super-greenhouse occur as part of the same physical phenomenon, and that the transition through the super-greenhouse to a local runaway greenhouse is intimately linked to the onset of deep convection. A runaway greenhouse occurs when water vapour causes the troposphere to become optically thick to thermal radiation from the surface and a limit on OLR emerges as thermal emission is from a constant temperature level aloft. This limit is modelled as 282 W/m/m [Goldblatt et al, 2013]. Using satellite data from Earth's tropics, we find an empirical value of this limit of 280 W/m/m, in excellent agreement with the model.A column transitioning to a runaway greenhouse typically overshoots the runaway limit and then OLR decreases with increasing surface temperature until the runaway limit is reached after which OLR remains constant. The term super-greenhouse effect (SGE) has been used to describe OLR decreasing with surface warming, observed in these satellite measurements. We show the SGE is one and the same as the transition to a local runaway greenhouse, and represents a fundamental shift in the radiation response of the earth system, rather than simply an extension of water vapour feedback. This transition via SGE from an optically thin to optically thick troposphere is facilitated by enhanced

A validated physical model of greenhouse climate

In the greenhouse model the momentaneous environmental crop growth factors are calculated as output, together with the physical behaviour of the crop. The boundary conditions for this model are the outside weather conditions; other inputs are the physical characteristics of the crop, of the greenhouse and of the control system. The greenhouse model is based on the energy, water vapour and CO 2 balances of the crop-greenhouse system. While the emphasis is on the dynamic behaviour of the greenhouse for implementation in continuous optimization, the state variables temperature, water vapour pressure and carbondioxide concentration in the relevant greenhouse parts crop, air, soil and cover are calculated from the balances over these parts. To do this in a proper way, the physical exchange processes between the system parts have to be quantified first. Therefore the greenhouse model is constructed from submodels describing these processes: a. Radiation transmission model for the modification of the outside to the inside global radiation. b. Ventilation model to describe the ventilation exchange between greenhouse and outside air. c. The description of the exchange of energy and mass between the crop and the greenhouse air. d. Calculation of the thermal radiation exchange between the various greenhouse parts. e. Quantification of the convective exchange processes between the greenhouse air and respectively the cover, the heating pipes and the soil surface and between the cover and the outside air. f. Determination of the heat conduction in the soil. The various submodels are validated first and then the complete greenhouse model is verified

Joseph Fourier's discovery of the greenhouse effect is discussed and is compared to the modern conception of the greenhouse effect. It is confirmed that what Fourier discovered is analogous to the modern concept of the greenhouse effect. However, the modern concept of the greenhouse effect is found to be based on a paradoxical analogy to Fourier's greenhouse work and so either Fourier's greenhouse work, the modern conception of the greenhouse effect, or the modern definition of heat is incorr...

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.

Greenhouses and their humanizing synergies

Greenhouses in space will require advanced technical systems of automatic watering, soil-less cultivation, artificial lighting, and computerized observation of plants. Functions discussed for plants in space habitats include physical/health requirements and human psychology, social cohesion, as well as the complex sensorial benefits of plants for humans. The authors consider the role of plants in long-term space missions historically since 1971 (Salyut 1) and propose a set of priorities to be considered within the design requirements for greenhouses and constructed environments given a range of benefits associated with plant-human relationships. They cite recent research into the use of greenhouses in extreme environments to reveal the relative importance of greenhouses for people living in isolated locations. Additionally, they put forward hypotheses about where greenhouses might factor into several strata of human health. In a recent design-in-use study of astronauts' experiences in space habitats discussed in Architecture for Astronauts (Springer Press 2011) it was found that besides the basic advantages for life support there are clearly additional "side benefits" for habitability and physical wellbeing, and thus long-term mission success. The authors have composed several key theses regarding the need to promote plant-human relationships in space, including areas where synergy and symbiosis occur. They cite new comprehensive research into the early US Space Program to reveal where programmatic requirements could be added to space architecture to increase the less quantifiable benefits to astronauts of art, recreation, and poetic engagement with their existential condition of estrangement from the planet. Specifically in terms of the technological requirements, the authors propose the integration of a new greenhouse subsystem component into space greenhouses—the Mobile Plant Cultivation Subsystem—a portable, personal greenhouse that can be integrated

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.

Effects of Low-Carbon Technologies and End-Use Electrification on Energy-Related Greenhouse Gases Mitigation in China by 2050

Directory of Open Access Journals (Sweden)

Zheng Guo

2015-07-01

Full Text Available Greenhouse gas emissions in China have been increasing in line with its energy consumption and economic growth. Major means for energy-related greenhouse gases mitigation in the foreseeable future are transition to less carbon intensive energy supplies and structural changes in energy consumption. In this paper, a bottom-up model is built to examine typical projected scenarios for energy supply and demand, with which trends of energy-related carbon dioxide emissions by 2050 can be analyzed. Results show that low-carbon technologies remain essential contributors to reducing emissions and altering emissions trends up to 2050. By pushing the limit of current practicality, emissions reduction can reach 20 to 28 percent and the advent of carbon peaking could shift from 2040 to 2030. In addition, the effect of electrification at end-use sectors is studied. Results show that electrifying transport could reduce emissions and bring the advent of carbon peaking forward, but the effect is less significant compared with low-carbon technologies. Moreover, it implies the importance of decarbonizing power supply before electrifying end-use sectors.

A Hiatus of the Greenhouse Effect

Song, Jinjie; Wang, Yuan; Tang, Jianping

2016-01-01

The rate at which the global average surface temperature is increasing has slowed down since the end of the last century. This study investigates whether this warming hiatus results from a change in the well-known greenhouse effect. Using long-term, reliable, and consistent observational data from the Earth’s surface and the top of the atmosphere (TOA), two monthly gridded atmospheric and surface greenhouse effect parameters (Ga and Gs) are estimated to represent the radiative warming effects of the atmosphere and the surface in the infrared range from 1979 to 2014. The atmospheric and surface greenhouse effect over the tropical monsoon-prone regions is found to contribute substantially to the global total. Furthermore, the downward tendency of cloud activity leads to a greenhouse effect hiatus after the early 1990 s, prior to the warming pause. Additionally, this pause in the greenhouse effect is mostly caused by the high number of La Niña events between 1991 and 2014. A strong La Niña indicates suppressed convection in the tropical central Pacific that reduces atmospheric water vapor content and cloud volume. This significantly weakened regional greenhouse effect offsets the enhanced warming influence in other places and decelerates the rising global greenhouse effect. This work suggests that the greenhouse effect hiatus can be served as an additional factor to cause the recent global warming slowdown. PMID:27616203

2010-05-26

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.

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.

Agricultural sources of greenhouse gas emissions

International Nuclear Information System (INIS)

Rochette, P.

2003-01-01

The author described different sources of greenhouse gas emissions resulting from agricultural activities and the process by which carbon dioxide, nitrous oxide, and methane are generated on Canadian farms. The author also proposed some practices that would contribute to the reduction of greenhouse gas emissions. A brief description of the greenhouse effect was also provided with special emphasis on the agricultural sector. In 1996, the Canadian agricultural sector was responsible for approximately 10 per cent of greenhouse gas emissions in the country. Given the increase in farm animals and more intensive agricultural activities, it is estimated that greenhouse gas emissions generated by the agricultural sector will increase by 20 per cent by 2010 if current practices remain in effect. The most optimistic scenarios indicate that the agricultural sector could achieve or even exceed Canada's Kyoto Protocol commitments mainly through organic material sequestration in soils. The possibility for farmers to sell greenhouse gas credits could motivate farmers into adopting various practices that reduce emissions of greenhouse gases. However, the author indicated that the best motivation for farmers is the fact that adopting such practices would also lead to more efficient agricultural production. 5 refs., 4 figs

Biological processes for mitigation of greenhouse gases

Energy Technology Data Exchange (ETDEWEB)

Benemann, John R. [California Univ., Dept. of Plant and Microbial Biology, Berkeley, CA (United States)

1999-07-01

Biological processes driven by photosynthesis cycle through the atmosphere well over an order of magnitude more CO{sub 2} than is currently emitted from the combustion of fossils fuels. Already human activities control and appropriate almost half the primary photosynthetic productivity of the planet. Better management of natural and man-made ecosystems affords many opportunities for mitigation of greenhouse gases, through sink enhancements, source reduction and substitution of fossil fuels with biofuels. Biofuels can be recovered from most organic wastes, from agricultural and forestry residues, and from biomass produced solely for energy use. However, the currently low costs of fossil fuels limits the market for biofuels. Accounting for the greenhouse mitigation value of biofuels would significantly increase their contribution to world fuel suppliers, estimated to be currently equivalent to about 15% of fossil fuel usage. Another limiting factor in expanding the use of biofuels is the relatively low solar energy conversion efficiencies of photosynthesis. Currently well below 1% of solar energy is converted into biomass energy even by intensive agricultural or forestry systems, with peak conversion efficiencies about 2 to 3% for sugar cane or microalgae cultures. One approach to increase photosynthetic efficiencies, being developed at the University of California Berkeley, is to reduce the amount of light-gathering chlorophyll in microalgae and higher plants. This would reduce mutual shading and also increase photosynthetic efficiencies under full sunlight intensities. Estimates of the potential of photosynthetic greenhouse mitigation processes vary widely. However, even conservative estimates for biofuels substituting for fossil fuels project the potential to reduce a large fraction of current increases in atmospheric CO{sub 2} levels. Biofuels production will require integration with existing agronomic, forestry and animal husbandry systems, and improved

Observational determination of the greenhouse effect

Science.gov (United States)

Raval, A.; Ramanathan, V.

1989-01-01

Satellite measurements are used to quantify the atmospheric greenhouse effect, defined here as the infrared radiation energy trapped by atmospheric gases and clouds. The greenhouse effect is found to increase significantly with sea surface temperature. The rate of increase gives compelling evidence for the positive feedback between surface temperature, water vapor and the greenhouse effect; the magnitude of the feedback is consistent with that predicted by climate models. This study demonstrates an effective method for directly monitoring, from space, future changes in the greenhouse effect.

Experiences of outreach workers in promoting smoking cessation to Bangladeshi and Pakistani men: longitudinal qualitative evaluation

Directory of Open Access Journals (Sweden)

Barton Pelham M

2011-06-01

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

Active engagement of scientists in Education and Public Outreach (E/PO) activities results in benefits for both the audience and scientists. Most scientists are trained in research but have little formal training in education. The Planetary Science Education and Public Outreach (E/PO) Forum helps the Science Mission Directorate support scientists currently involved in E/PO and to help scientists who are interested in becoming involved in E/PO efforts find ways to do so through a variety of avenues. We will present current and future opportunities and resources for scientists to become engaged in education and public outreach. These include upcoming NASA SMD E/PO funding opportunities, professional development resources for writing NASA SMD E/PO proposals (webinars and other online tools), toolkits for scientists interested in best practices in E/PO (online guides for K-12 education and public outreach), EarthSpace (a community web space where instructors can find and share about teaching space and earth sciences in the undergraduate classroom, including class materials news and funding opportunities, and the latest education research), thematic resources for teaching about the solar system (archived resources from Year of the Solar System), and an online database of scientists interested in connecting with education programs.

Pattison, Natalie; Eastham, Elizabeth

2012-01-01

To explore referrals to a critical care outreach team (CCOT), associated factors around patient management and survival to discharge, and the qualitative exploration of referral characteristics (identifying any areas for service improvement around CCOT). A single-centre mixed method study in a specialist hospital was undertaken, using an explanatory design: participant selection model. In this model, quantitative results (prospective and retrospective episode of care review, including modified early warning system (MEWS), time and delay of referral and patient outcomes for admission and survival) are further explained by qualitative (interview) data with doctors and nurses referring to outreach. Quantitative data were analysed using SPSS +17 and 19, and qualitative data were analysed using grounded theory principles. A large proportion of referrals (124/407 = 30·5%) were made by medical staff. For 97 (97/407 = 23·8%) referrals, there was a delay between the point at which patients deteriorated (as verified by retrospective record review and MEWS score triggers) and the time at when patients were referred. The average delay was 2·96 h (95% CI 1·97-3·95; SD 9·56). Timely referrals were associated with improved outcomes; however, no causal attribution can be made from the circumstances around CCOT referral. Qualitative themes included indications for referral, facilitating factors for referral, barriers to referral and consequences of referral, with an overarching core theory of reassurance. Outreach was seen as back-up and this core theory demonstrates the important, and somewhat less tangible, role outreach has in supporting ward staff to care for at-risk patients. Mapping outreach episodes of care and patient outcomes can help highlight areas for improvement. This study outlines reasons for referral and how outreach can facilitate patient pathways in critical illness. © 2011 The Authors.

The greenhouse effect of planetary atmospheres

International Nuclear Information System (INIS)

Kondratyev, K.Ya.; Moskalenko, N.I.

1980-01-01

The greenhouse effect of the atmosphere is the main factor of possible climate changes of anthropogenic origin. The growing pollution of the atmosphere leads to an increase of the concentration of various gaseous components. Of great importance is also the consideration of the aerosols. All the gaseous components, as well as aerosols, have the absorption bands in the IR spectral range. The traditional attention to the problem of the CO 2 contribution to the greenhouse effect has somewhat overshadowed the significance of the different components. The data characterizing the significance of the different components of the greenhouse effect are considered. The results of studying the absorption spectra of methane, nitrous oxides, sulphuric gas, ammonia, nitric-acid vapours and other components are discussed. The assessments of their contribution to the greenhouse effect are given. The important role of the small-size fraction of the atmospheric aerosols as a factor of the greenhouse effect is discussed. Both the analysis of the causes of the Earth's climate variability and the relevant investigation of the atmospheric greenhouse effect determine the expediency of analysing the conditions of the greenhouse effect formation on other planets. Laboratory studies of the IR absorption spectra of synthetic CO 2 atmospheres were carried out. Some results from these studies are discussed. (author)

Economic growth and greenhouse gas emissions

Recent empirical research has examined the relationship between certain indicators of environmental degradation and income, concluding that in some cases an inverted U-shaped relationship, which has been called an environmental Kuznets curve (EKC), exists between these variables. Unfortunately, this inverted U-shaped relationship does not hold for greenhouse gas emissions. One explanation of the absence of EKC-like behavior in greenhouse gas emissions is that greenhouse gases are special pollutants that create global, not local, disutility. But the international nature of global warming is not the only reason that prevents de-linking greenhouse gas emissions from economic growth. The intergenerational nature of the negative impact of greenhouse gas emissions may have also been an important factor preventing the implementation of greenhouse gas abatement measures in the past. In this paper we explore the effect that the presence of intergenerational spillovers has on the emissions-income relationship. We use a numerically calibrated overlapping generations model of climate-economy interactions. We conclude that: (1) the intertemporal responsibility of the regulatory agency, (2) the institutional capacity to make intergenerational transfers and (3) the presence of intergenerationally lagged impact of emissions constitute important determinants of the relationship between economic growth and greenhouse gas emissions.

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.

2006-04-01

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.

2009-06-01

Natural optical phenomena enjoy a level of interest sufficiently high among a wide array of people to provide ideal education and outreach opportunities. The aurora promotes particularly high interest, perhaps because of its relative rarity in the areas of the world where most people live. A project is being conducted at Montana State University to use common interest and curiosity about auroras to motivate learning and outreach through the design and deployment of optical sensor systems that detect the presence of an auroral display and send cell phone messages to alert interested people. Project participants learn about the physics and optics of the aurora, basic principles of optical system design, radiometric calculations and calibrations, electro-optical detectors, electronics, embedded computer systems, and computer software. The project is moving into a stage where it will provide greatly expanded outreach and education opportunities as optical aurora detector kits are created and disbursed to colleges around our region.

At our hospital the current model of care for children with moderate-severe CF is focused on intensive inpatient intervention, regular outpatient clinic review and specialist outreach care as required. An alternative model providing more regular physiotherapy and dietetic outreach support, in addition to these specialist services, may be more effective. 16 children (4 male; 12 female; mean age 10.9±2.93; range 4-15 years) who required >40days of IV antibiotics in the 12-months pre-intervention were enrolled. Physiotherapy included weekly-supervised exercise sessions, alongside regular review of home physiotherapy regimens. Dietetic management included 1-2 monthly monitoring of growth, appetite, intake and absorption, and nutrition education sessions. There was a 23% reduction in inpatient IV antibiotic requirement and 20% reduction in home IV antibiotic requirement during the intervention year. Cost-benefit analyses showed savings of £113,570. VO(2Peak) increased by 4.9 ml·kg·min(-1) (95%CI 1.01 to 8.71; p=0.02), and 10 m-MSWT distance and increment achieved increased by 229 m (95%CI 109 to 350; pchildren with moderate-severe CF.

Greenhouse Module for Space System: A Lunar Greenhouse Design

Directory of Open Access Journals (Sweden)

Zeidler Conrad

2017-02-01

Full Text Available In the next 10 to 20 years humankind will return to the Moon and/or travel to Mars. It is likely that astronauts will eventually build permanent settlements there, as a base for long-term crew tended research tasks. It is obvious that the crew of such settlements will need food to survive. With current mission architectures the provision of food for longduration missions away from Earth requires a significant number of resupply flights. Furthermore, it would be infeasible to provide the crew with continuous access to fresh produce, specifically crops with high water content such as tomatoes and peppers, on account of their limited shelf life. A greenhouse as an integrated part of a planetary surface base would be one solution to solve this challenge for long-duration missions. Astronauts could grow their own fresh fruit and vegetables in-situ to be more independent from supply from Earth. This paper presents the results of the design project for such a greenhouse, which was carried out by DLR and its partners within the framework of the Micro-Ecological Life Support System Alternative (MELiSSA program. The consortium performed an extensive system analysis followed by a definition of system and subsystem requirements for greenhouse modules. Over 270 requirements were defined in this process. Afterwards the consortium performed an in-depth analysis of illumination strategies, potential growth accommodations and shapes for the external structure. Five different options for the outer shape were investigated, each of them with a set of possible internal configurations. Using the Analytical Hierarchy Process, the different concept options were evaluated and ranked against each other. The design option with the highest ranking was an inflatable outer structure with a rigid inner core, in which the subsystems are mounted. The inflatable shell is wrapped around the core during launch and transit to the lunar surface. The paper provides an overview of the

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 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 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.

Greenhouse effect of NO{sub x}

Energy Technology Data Exchange (ETDEWEB)

Lammel, G; Grassl, H [Max-Planck-Institut fuer Meteorologie, Hamburg (Germany)

1995-07-01

Through various processes the nitrogen oxides (NO{sub x}) interact with trace gases in the troposphere and stratosphere which do absorb in the spectral range relevant to the greenhouse effect (infrared wavelengths). The net effect is an enhancement of the greenhouse effect. The catalytic role of NO{sub x} in the production of tropospheric ozone provides the most prominent contribution. The global waming potential is estimated as GWP (NO{sub x}) = 30-33 and 7-10 for the respective time horizons of 20 and 100 years, and is thereby comparable to that of methane. NO{sub x} emissions in rural areas of anthropogenically influenced regions, or those in the vicinity of the tropopause caused by air traffic, cause the greenhouse effectivity to be substantially more intense. We estimate an additional 5-23% for Germany`s contribution to the anthropogenic greenhouse effect as a result of the indirect greenhouse effects stemming from NO{sub x}. Furthermore, a small and still inaccurately defined amount of the deposited NO{sub x} which has primarily been converted into nitrates is again released from the soil into the atmosphere in the form of the long-lived greenhouse gas nitrous oxide (N{sub i}O). Thus, anthropogenically induced NO{sub x} emissions contribute to enhanced greenhouse effect and to stratospheric ozone depletion in the time scale of more than a century. (orig.)

2017-12-01

A five-year USDA-funded study titled "Resilience and vulnerability of beef cattle production in the Southern Great Plains under changing climate, land use, and markets" was initiated as a multi-institutional collaboration involving Texas Institute for Applied Environmental Research (TIAER)—Tarleton State University, United States Department of Agriculture (USDA)—Agricultural Research Service (ARS) in El Reno, Oklahoma, USDA—ARS in Bushland, Texas, Kansas State University, Oklahoma State University, University of Oklahoma, and the Noble Research Institute in Ardmore, Oklahoma. The project goal is to safeguard and promote regional beef production while mitigating its environmental footprint. Conducting a full Life Cycle Analysis (LCA) is one of the major objectives of the study, in addition to field experiments, extension, outreach, and education. Estimation of all the resource use and greenhouse gas emissions are parts of the LCA. A computer model titled Animal Production Life Cycle Analysis Tool (APLCAT) is developed and applied to conduct the LCA on beef cattle production in the study region. The model estimates water use, energy requirements, and emissions of enteric methane, manure methane, nitrous oxide, and carbon dioxide. Also included in the LCA analysis are land-atmospheric exchanges of methane, nitrous oxide, carbon dioxide and the global warming potential. Our study is focused on the cow-calf and stocker phases of beef cattle production. The animal production system in the study region is predominantly forage based with protein and energy supplements when needed. Spring calving typical to the study region. In the cow-calf phase animals typically graze native prairie although introduced pasture grazing is also prevalent. Stockers use winter pasture as the major feed. The results of greenhouse gas emissions summarized per kg of hot carcass weight or animal fed will be presented.

Climate Golden Age or Greenhouse Gas Dark Age Legacy?

Science.gov (United States)

Carter, P.

2016-12-01

Relying on the IPCC Assessments, this paper assesses legacy from total committed global warming over centuries, correlated with comprehensive projected impacts. Socio-economic inertia, climate system inertia, atmospheric greenhouse gas (GHG) concentrations, amplifying feedback emissions, and unmasking of cooling aerosols are determinants. Stabilization of global temperature (and ocean acidification for CO2) requires emissions of "long lived greenhouse gases" to be "about zero," including feedbacks. "The feedback … is positive" this century; many large feedback sources tend to be self- and inter-reinforcing. Only timely total conversion of all fossil fuel power to clean, virtually zero-carbon renewable power can achieve virtual zero carbon emissions. This results in multiple, increasing benefits for the entire world population of today's and all future generations, as laid out here. Conversions of methane- and nitrous oxide-emitting sources have large benefits. Without timely conversion to virtual zero emissions, the global climate and ocean disruptions are predicted to become progressively more severe and practically irreversible. "Continued emission of greenhouse gases will increase the likelihood of severe, pervasive and irreversible impacts for people and ecosystems." Crop yields in all main food-producing regions are projected to decline progressively with rising temperature (as proxy to multiple adverse effects) (AR5). Ocean heating, acidification, and de-oxygenation are projected to increase under all scenarios, as is species extinction. The legacy for humanity depends on reducing long-lived global emissions fast enough to virtual zero. Today's surface warming with unprecedented and accelerating atmospheric GHG concentrations requires an immediate response. The only IPCC scenario to possibly meet this and not exceed 2ºC by and after 2100 is the best-case RCP2.6, which requires CO2 eq. emissions to peak right away and decline at the latest by 2020.

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.

An easy physics outreach and teaching tool for holography

International Nuclear Information System (INIS)

Voslion, T; Escarguel, A

2013-01-01

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.

Lay perceptions of the greenhouse effect

Peretti-Watel, P.; Hammer, B.

2006-01-01

Using the data from the French Environment Barometer EDF-RD 2004 (national representative sample of French citizens aged over 15) and surveys by ADEME between 2000 and 2005, the paper investigates lay perceptions of the causes and consequences of the greenhouse effect, which may be considered as archetypical of contemporary environmental risks. Beyond lay lack of knowledge, the greenhouse effect gives rise to coherent and meaningful cognitions, including causal explanations, shaped by the pre-existing cognitive framework. This cognitive work, based on analogic rather than scientific thought, strings together the greenhouse effect, ozone depletion, air pollution and even nuclear power. The cognitive process is also fed by the individuals' general conceptions of Nature and of the rights and duties of humankind towards Nature. People are not greatly worried about the unseen and controversial consequences of the greenhouse effect: such worry could be one of those 'elite fears' mentioned by Beck. Finally, while the efficiency of public policies to counter the greenhouse effect requires extensive societal involvement, low confidence towards both political and scientific authorities may prevent the population from becoming aware of the environmental stakes tied to the greenhouse effect.

Davis, Matthew C.; Rocque, Brandon G.; Singhal, Ash; Ridder, Tom; Pattisapu, Jogi V.; Johnston, James M.

2017-01-01

Object Neurosurgical services are increasingly recognized as essential components of surgical care worldwide. Degree of interest among neurosurgeons regarding international work, and barriers to involvement in global neurosurgical outreach, are largely unexplored. We distributed a survey to members of the AANS/CNS Joint Section on Pediatric Neurosurgery to assess the state of global outreach among its members and identify barriers to involvement. Methods An internet-based questionnaire was developed by the International Education Subcommittee of the AANS/CNS Joint Section on Pediatric Neurosurgery, and distributed to pediatric neurosurgeons via the AANS/CNS Joint Section email contact list. Participants were surveyed on involvement in global neurosurgical outreach, geographic location, nature of participation, and barriers to further involvement. Results A 35.3% response rate was obtained, with 116 respondents completed the survey. 61% performed or taught neurosurgery in a developing country, 49% traveling at least annually. Africa was the most common region (54%), followed by South America (30%), through 29 separate organizing entities. Hydrocephalus was the most commonly treated condition (88%), followed by spinal dysraphism (74%) and tumor (68%). Most respondents obtained follow-up through communication from local surgeons (77%). 71% believed the international experience improved their practice, and 74% were very or extremely interested in working elsewhere. Interference with current practice (61%), cost (44%), and difficulty identifying international partners (43%) were the most commonly cited barriers to participation. Conclusion Any coordinated effort to expand global neurosurgical capacity begins with appreciation for the current state of outreach efforts. Increasing participation in global outreach will require addressing both real and perceived barriers to involvement.

Other outreach includes High School Science Day, school partnerships, teacher and student mentoring and the San Diego Science Alliance [http://www.sdsa.org].

Nuclear energy and the greenhouse effect

International Nuclear Information System (INIS)

Weinberg, A.M.

1990-01-01

The extent and nature of the greenhouse effect are examined and placed in an environmental and historical context. The effect of energy policies on the greenhouse effect are discussed and the offending countries are identified. What energy policies would mitigate the greenhouse effect, and yet make good sense whether or not the effect proves to be real? Conservation is a desirable though not completely understood strategy. Conservation may not be a better bet in every instance than is increase in supply. If the greenhouse effect turns out to be real, nuclear energy can be one of the supply options that we turn to. If the greenhouse effect turns out to be false, and acceptable, economic nuclear option is surely better than one that does nothing but create strife and dissension. Let us remember that nuclear energy is the only large-scale non-fossil source other than hydropower that has been demonstrated to be practical. (author)

GREENHOUSE GASES AND MEANS OF PREVENTION

Directory of Open Access Journals (Sweden)

Dušica Stojanović

2013-09-01

Full Text Available The greenhouse effect can be defined as the consequence of increased heating of the Earth's surface, as well as the lower atmosphere by carbon dioxide, water vapor, and other trace amounts gases. It is well-known that human industrial activities have released large amounts of greenhouse gases in the atmosphere, about 900 billion tons of carbon dioxide, and it is estimated that up to 450 billion are still in the atmosphere. In comparison to greenhouse gases water vapor is one of the greatest contributors to the greenhouse effect on Earth. Many projects, as does the PURGE project, have tendences to build on the already conducted research and to quantify the positive and negative impacts on health and wellbeing of the population with greenhouse gas reduction strategies that are curently being implemented and should be increasingly applied in various sectors and urban areas, having offices in Europe, China and India.

Greenhouses provide a controlled environment that is suitable for plants growth and cultivation. In this paper the maximum temperature change inside the greenhouse is to be reduced by the use of energy storage in a phase change material PCM. A mathematical model is developed for the storage material and for the greenhouse. The coupled models are solved using numerical methods and Java code program. The effect of different parameters on the inside greenhouse temperature is investigated. The temperature swing between maximum and minimum values during 24 h can be reduced by 3-5 deg. C using the PCM storage. This can be improved further by enhancing the heat transfer between the PCM storage and the air inside the greenhouse

Among atmospheric scientists, the importance of the Earth radiation budget concept is well understood. Papers have addressed the topic for over 100 years, and the large Clouds and the Earth's Radiant Energy System (CERES) science team (among others), with its multiple on-orbit instruments, is working hard to quantify the details of its various parts. In education, Earth's energy budget is a concept that generally appears in middle school and Earth science curricula, but its treatment in textbooks leaves much to be desired. Students and the public hold many misconceptions, and very few people have an appreciation for the importance of this energy balance to the conditions on Earth. More importantly, few have a correct mental model that allows them to make predictions and understand the effect of changes such as increasing greenhouse gas concentrations. As an outreach element of the core CERES team at NASA Langley, a multi-disciplinary group of scientists, educators, graphic artists, writers, and web developers has been developing and refining graphics and resources to explain the Earth's Energy budget over the last few decades. Resources have developed through an iterative process involving ongoing use in front of a variety of audiences, including students and teachers from 3rd to 12th grade as well as public audiences.

Showstack, Randy

While nations decide on whether to sign on to the Kyoto Protocol on climate change, some countries and private companies are moving forward with greenhouse gas emissions trading.A 19 March report, "The Emerging International Greenhouse Gas Market," by the Pew Center on Global Climate Change, reports that about 65 greenhouse gas emissions trades for quantities above 1,000 metric tons of carbon dioxideequivalent already have occurred worldwide since 1996. Many of these trades have taken place under a voluntary, ad hoc framework, though the United Kingdom and Denmark have established their own domestic emissions trading programs.

Peer-led outreach is a critical element of HIV and STI-reduction interventions aimed at sex workers. We study the association between peer-led outreach to sex workers and the time to utilize health facilities for timely STI syndromic-detection and treatment. Using data on the timing of peer-outreach interventions and clinic visits, we utilize an Extended Cox model to assess whether peer educator outreach intensity is associated with accelerated clinic utilization among sex workers. Our data comes from 2705 female sex workers registered into Pragati, a women-in-sex-work outreach program, and followed from 2008 through 2012. We analyze this data using an Extended Cox model with the density of peer educator visits in a 30-day rolling window as the key predictor, while controlling for the sex workers' age, client volume, location of sex work, and education level. The principal outcome of interest is the timing of the first voluntary clinic utilization. More frequent peer visit is associated with earlier first clinic visit (HR: 1.83, 95% CI, 1.75-1.91, p educator outreach. Peer outreach density is associated with increased likelihood of-and shortened duration to-clinic utilization among female sex workers, suggesting potential staff resourcing implications. Given the observational nature of our study, however, these findings should be interpreted as an association rather than as a causal relationship.

Greenhouse gas strategy

International Nuclear Information System (INIS)

2001-03-01

Because the overall effects of climate change will likely be more pronounced in the North than in other parts of the country, the Government of the Northwest Territories considers it imperative to support global and local actions to reduce greenhouse gas emissions. Government support is manifested through a coordinating role played by senior government representatives in the development of the NWT Greenhouse Gas Strategy, and by participation on a multi-party working committee to identify and coordinate northern actions and to contribute a northern perspective to Canada's National Climate Change Implementation Strategy. This document outlines the NWT Government's goals and objectives regarding greenhouse gas emission reduction actions. These will include efforts to enhance awareness and understanding; demonstrate leadership by putting the Government's own house in order; encouraging action across sectors; promote technology development and innovation; invest in knowledge and building the foundation for informed future decisions. The strategy also outlines the challenges peculiar to the NWT, such as the high per person carbon dioxide emissions compared to the national average (30 tonnes per person per year as opposed to the national average of 21 tonnes per person per year) and the increasing economic activity in the Territories, most of which are resource-based and therefore energy-intensive. Appendices which form part of the greenhouse gas strategy document, provide details of the potential climate change impact in the NWT, a detailed explanation of the proposed measures, an emission forecast to 2004 from industrial processes, fuel combustion and incineration, and a statement of the official position of the Government of the NWT on climate change

[A peak recognition algorithm designed for chromatographic peaks of transformer oil].

Ou, Linjun; Cao, Jian

2014-09-01

In the field of the chromatographic peak identification of the transformer oil, the traditional first-order derivative requires slope threshold to achieve peak identification. In terms of its shortcomings of low automation and easy distortion, the first-order derivative method was improved by applying the moving average iterative method and the normalized analysis techniques to identify the peaks. Accurate identification of the chromatographic peaks was realized through using multiple iterations of the moving average of signal curves and square wave curves to determine the optimal value of the normalized peak identification parameters, combined with the absolute peak retention times and peak window. The experimental results show that this algorithm can accurately identify the peaks and is not sensitive to the noise, the chromatographic peak width or the peak shape changes. It has strong adaptability to meet the on-site requirements of online monitoring devices of dissolved gases in transformer oil.

Enrolling Underserved Women in mHealth Programs: Results From Text4baby Outreach Campaigns.

Bushar, Jessica A; Fishman, Jodie; Garfinkel, Danielle; Pirretti, Amy

2018-03-01

Public health practitioners have increasingly leveraged technology-based communication to get health information into the hands of hard-to-reach populations; however, best practices for outreach and enrollment into mobile health (mHealth) programs are lacking. This article describes enrollment results from campaigns focused on enrolling underserved pregnant women and mothers in Text4baby-a free, mHealth service-to inform outreach strategies for mHealth programs. Text4baby participants receive health and safety information, interactive surveys, alerts, and appointment reminders through at least three weekly texts and a free app-timed to users' due date or babies' birth date. Text4baby worked with partners to implement national, state, and community-based enrollment campaigns. Descriptive statistics were used to compare baseline enrollment prior to a campaign with enrollment during a campaign to generate enrollment estimates. Enrollment rates were calculated for campaigns for which the number targeted/reached was available. National television campaigns resulted in more than 10,000 estimated enrollments. Campaigns that were integrated with an existing program and text-based recruitment had the highest enrollment rates, ranging from 7% to 24%. Facebook advertisements and traditional media targeting providers and consumers were least effective. mHealth programs should consider text-based recruitment and outreach via existing programs; additional research is needed on return on investment for different outreach strategies and on the effectiveness of different outreach strategies at reaching and enrolling specific target populations.

Psychiatric street outreach to homeless people: fostering relationship, reconnection, and recovery.

Christensen, Richard C

2009-11-01

Individuals who suffer from serious and persistent mental illnesses constitute nearly one-third of the homeless population in this country. Perhaps the most vulnerable people in the homeless population are those who are disabled from a mental illness and are also chronically unsheltered. Psychiatric street outreach to this particular segment of the homeless population is commonly justified based upon the need to engage the most severely impaired and most medically underserved individuals in our communities assertively. This brief paper describes the core objectives of fostering relationship, reconnection, and recovery through a transdisciplinary, psychiatric street outreach initiative in Jacksonville, Florida.

2017-06-28

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.

Voluntary reporting of greenhouse gases, 1995

The Voluntary Reporting Program for greenhouse gases is part of an attempt by the U.S. Government to develop innovative, low-cost, and nonregulatory approaches to limit emissions of greenhouse gases. It is one element in an array of such programs introduced in recent years as part of the effort being made by the United States to comply with its national commitment to stabilize emissions of greenhouse gases under the Framework Convention on Climate Change. The Voluntary Reporting Program, developed pursuant to Section 1605(b) of the Energy Policy Act of 1992, permits corporations, government agencies, households, and voluntary organizations to report to the Energy Information Administration (EIA) on actions taken that have reduced or avoided emissions of greenhouse gases.

Air-conditioning Australian households: The impact of dynamic peak pricing

International Nuclear Information System (INIS)

Strengers, Yolande

2010-01-01

International mandates for smart metering are enabling variable and real-time pricing regimes such as dynamic peak pricing (DPP), which charges 10-40 times the off-peak rate for electricity during short periods. This regime aims to reduce peak electricity demand (predominantly due to increase in residential air-conditioning usage) and curb greenhouse gas emissions. Although trials indicate that DPP can achieve significant demand reductions, particularly in summer, little is known about how or why households change their cooling practices in response to this strategy. This paper discusses the outcomes of a small qualitative study assessing the impact of a DPP trial on household cooling practices in the Australian state of New South Wales. The study challenges common assumptions about the necessity of air-conditioning and impact of price signals. It finds that DPP engages households as co-managers of their cooling practices through a series of notification signals (SMS, phone, in-home display, email, etc.). Further, by linking the price signal to air-conditioning, some householders consider this practice discretionary for short periods of time. The paper concludes by warning that policy makers and utilities may serve to legitimise air-conditioning usage and/or negate demand reductions by failing to acknowledge the non-rational dynamics of DPP and household cooling practices. - Research highlights: →Most householders consider air-conditioning discretionary during DPP events →DPP engages householders as co-managers of their demand →Notification of an upcoming DPP event is significant to the response →Householders feel obligated to respond to DPP for a range of non-financial reasons

Growing Physics and Astronomy Public Outreach in Montreal

Simard, Gabrielle; Lepo, Kelly

2017-01-01

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.

A project-based course about outreach in a physics curriculum

Bobroff, Julien; Bouquet, Frédéric

2016-07-01

We describe an undergraduate course where physics students are asked to conceive an outreach project of their own. This project-based-learning course alternates between the project conception and teaching activities about outreach. It ends in a public show. Students decide the topic and format on their own. An analysis of the students’ productions over three years shows that all physics fields were equally covered, and various formats were used (experimental devices, animation or fiction movies, games, live events, photography). Some typical examples are described. We also analyse the benefits of this approach from the students’ perspective, through a survey done over three classes. Students showed an overall very good assessment of the course (average of 4.5(0.6) on an appreciation scale from 1 to 5) and recognised having developed outreach skills but also project-management and group-work know-how. They acknowledged this course to be a unique opportunity to share with an audience their interest in physics compared to other courses. They further mentioned that it served as an intermission in a classical academic curriculum. They also point out some challenges, especially the time-consuming issue. This survey together with the practical description of the course implementation should help other universities develop similar courses.

Comparison on the heat requirements of a four-span greenhouse with a melting snow system and a single-span greenhouse

International Nuclear Information System (INIS)

Furuno, S.; Sase, S.; Ishii, M.

2004-01-01

The heat requirements were measured and compared between a four-span greenhouse with a melting snow system and a typical single-span greenhouse with no melting snow system. Generally, single-span greenhouses require no melting snow system because snow drops off naturally from the roofs by gravity. The results for the four-span greenhouse showed that the provided heat by a heater for melting snow increased with an increase in snowfall, and there was a high correlation between them. The heat requirement per unit floor area of the four-span greenhouse was slightly less than that of the single-span greenhouse. This suggests that the decrease in heat requirement for internal air because of the larger floor/surface area ratio of the four-span greenhouse was more than the increase in heat requirement for melting snow. The measured heat requirement of the four-span greenhouse with the melting snow system was equal to the estimated heat load based on a common calculation procedure. On the other hand, that of the single-span greenhouse was slightly smaller than the estimated heat load. These suggest that the estimated heat load based on the common calculation procedure was slightly overestimated and larger than the actual heat requirement excluding the heat for the melting snow in snowy area. This is likely due to the fact that the parameters in the common calculation procedure were determined under the condition of larger net radiation than that in snowy area

Greenhouse gas mitigation options for Washington State

Energy Technology Data Exchange (ETDEWEB)

Garcia, N.

1996-04-01

President Clinton, in 1993, established a goal for the United States to return emissions of greenhouse gases to 1990 levels by the year 2000. One effort established to help meet this goal was a three part Environmental Protection Agency state grant program. Washington State completed part one of this program with the release of the 1990 greenhouse gas emissions inventory and 2010 projected inventory. This document completes part two by detailing alternative greenhouse gas mitigation options. In part three of the program EPA, working in partnership with the States, may help fund innovative greenhouse gas reduction strategies. The greenhouse gas control options analyzed in this report have a wide range of greenhouse gas reductions, costs, and implementation requirements. In order to select and implement a prudent mix of control strategies, policy makers need to have some notion of the potential change in climate, the consequences of that change and the uncertainties contained therein. By understanding the risks of climate change, policy makers can better balance the use of scarce public resources for concerns that are immediate and present against those that affect future generations. Therefore, prior to analyzing alternative greenhouse gas control measures, this report briefly describes the phenomenon and uncertainties of global climate change, and then projects the likely consequences for Washington state.

Greenhouse governance: An Australian iconoclast`s view

Energy Technology Data Exchange (ETDEWEB)

O`Brien, B.J. [Brian J O`Brien Associates Pty Ltd, Floreat Park, WA (Australia)

1996-10-01

The `No Regrets` policy was an imported stop-gap measure taken over five years ago when greenhouse fears were large and knowledge small. This paper suggests that this policy by 1995 is actually a `Three Regrets Policy` for Australia. Regret 1 is that El Nino effects which greatly affect Australia are given lower priority than greenhouse. Regret 2 is the deteriorating image and role of Science and Engineering in Australian society. Regret 3 is the growing domination of the energy debate by greenhouse. It is suggested that greenhouse fears should be put into an updated Australian perspective. The issues of sea level rise, and increasing temperatures are updated. It is believed that recognition of the importance of natural climate variation is increasing, this is not yet being used to put greenhouse into popular perspective. The paper concludes with five suggested actions to turn the `Three Regrets for Australia` into one that truly is `no regrets` for Australia. Putting greenhouse in perspective means a vigorous program of investigating and gradually understanding the whole suite of influences on the climate, natural as well as greenhouse. It includes making a competitive advantage out of the climate variabilities in Australia, from more accurate seasonal forecasts. (author). 3 tabs., 4 figs., refs.

Emissions Scenarios and Fossil-fuel Peaking

Science.gov (United States)

Brecha, R.

2008-12-01

Intergovernmental Panel on Climate Change (IPCC) emissions scenarios are based on detailed energy system models in which demographics, technology and economics are used to generate projections of future world energy consumption, and therefore, of greenhouse gas emissions. Built into the assumptions for these scenarios are estimates for ultimately recoverable resources of various fossil fuels. There is a growing chorus of critics who believe that the true extent of recoverable fossil resources is much smaller than the amounts taken as a baseline for the IPCC scenarios. In a climate optimist camp are those who contend that "peak oil" will lead to a switch to renewable energy sources, while others point out that high prices for oil caused by supply limitations could very well lead to a transition to liquid fuels that actually increase total carbon emissions. We examine a third scenario in which high energy prices, which are correlated with increasing infrastructure, exploration and development costs, conspire to limit the potential for making a switch to coal or natural gas for liquid fuels. In addition, the same increasing costs limit the potential for expansion of tar sand and shale oil recovery. In our qualitative model of the energy system, backed by data from short- and medium-term trends, we have a useful way to gain a sense of potential carbon emission bounds. A bound for 21st century emissions is investigated based on two assumptions: first, that extractable fossil-fuel resources follow the trends assumed by "peak oil" adherents, and second, that little is done in the way of climate mitigation policies. If resources, and perhaps more importantly, extraction rates, of fossil fuels are limited compared to assumptions in the emissions scenarios, a situation can arise in which emissions are supply-driven. However, we show that even in this "peak fossil-fuel" limit, carbon emissions are high enough to surpass 550 ppm or 2°C climate protection guardrails. Some

Technological substitution options for controlling greenhouse gas emissions

International Nuclear Information System (INIS)

Barbier, E.B.; Burgess, J.C.; Pearce, D.W.

1991-01-01

This chapter is concerned with technological options for greenhouse gas substitution. The authors interpret the term substitution to exclude energy conservation/efficiency measures, investments in afforestation (sinks), and greenhouse gas removal or abatement technologies. Their working definition of greenhouse gas substitution includes (1) replacement technologies, for example, substituting a greenhouse gas technology with a nongreenhouse gas technology; and (2) reduction technologies, for example, substituting a greenhouse gas technology with an alternative technology that reduces greenhouse gas emissions. Essentially, replacement technologies involve 100 percent reduction in CO 2 ; reduction technologies involve a partial reduction in CO 2 . Of the man-made sources of greenhouse gases, energy is the most important and is expected to contribute to at least half of the global warming effect in the near future. The majority of this impact is from fossil fuel combustion as a source of carbon dioxide (CO 2 ), although fossil fuels also contribute significantly to methane (CH 4 ), to nitrous oxide (N 2 O), and to low-level ozone (O 3 ) through production of various nitrogen gases (NO x ) and carbon monoxide (CO). This study analyzes the available greenhouse gas substitutions and their costs. The authors concentrate particularly on substitutions for fossil-fuel combustion and CFC production and consumption. They conclude by summarizing the potential for greenhouse gas substitution, the cost-effectiveness of the various options and the design of incentives for substitution

Peer outreach work as economic activity: implications for HIV prevention interventions among female sex workers.

Directory of Open Access Journals (Sweden)

Annie George

Full Text Available Female sex workers (FSWs who work as peer outreach workers in HIV prevention programs are drawn from poor socio-economic groups and consider outreach work, among other things, as an economic activity. Yet, while successful HIV prevention outcomes by such programs are attributed in part to the work of peers who have dense relations with FSW communities, there is scant discussion of the economic implications for FSWs of their work as peers. Using observational data obtained from an HIV prevention intervention for FSWs in south India, we examined the economic benefits and costs to peers of doing outreach work and their implications for sex workers' economic security. We found that peers considered their payment incommensurate with their workload, experienced long delays receiving compensation, and at times had to advance money from their pockets to do their assigned peer outreach work. For the intervention these conditions resulted in peer attrition and difficulties in recruitment of new peer workers. We discuss the implications of these findings for uptake of services, and the possibility of reaching desired HIV outcomes. Inadequate and irregular compensation to peers and inadequate budgetary outlays to perform their community-based outreach work could weaken peers' relationships with FSW community members, undermine the effectiveness of peer-mediated HIV prevention programs and invalidate arguments for the use of peers.

Outreach Programmes for Education and Training: Contributions from the International Cartographic Association

Cartwright, W. E.; Fairbairn, D.

2012-07-01

Organisations like the International Cartographic Association champion programmes that develop and deliver education and training to cartographers and geospatial scientists, globally. This can be in the form of traditional university and training college programmes, short courses for professional and technical members of mapping agencies and as outreach initiatives to transfer knowledge about the discipline and its contemporary practices. Through its international community, the ICA undertakes the transfer of knowledge about cartography and GI Science by publishing books and special editions of journals and running workshops. Colleagues from the ICA community conduct these workshops on a volunteer basis, generally with the support of the national member organisation of ICA or the national mapping body. For example, the ICA promotes the generation of extensive publications, generally through its Commissions and Working Groups. The publications include books, journals and the ICA Newsletter. Outreach activities are especially pertinent to up skill colleagues from developing countries. Specialist programmes can be offered for professional and 'everyday' map users (from adults to children). The ICA can assist with its current programmes, designed to embrace professional and non-professional cartographers alike. This paper will address how education and outreach programmes can be supported by international associations, by offering programmes independently, or in partnership with sister associations and national and regional organisations and societies. As well, the paper will address the need to deliver education and outreach programmes not to just the professional international community, but also to map users and citizen map publishers.

Nuclear power and the greenhouse effect

Donaldson, D; Tolland, H.; Grimston, M.

1990-01-01

The greenhouse effect is first explained. The evidence is shown in global warming and changing weather patterns which are generally believed to be due to the emission of greenhouse gases, including carbon dioxide. Serious consequences are predicted if emission of the greenhouse gases is not reduced. Sources of these gases are identified - agriculture, carbon fluorocarbons, coal-fired power stations, vehicle exhausts. The need is to use energy more efficiently but such measures as combined heat and power stations, more fuel efficient cars and better thermal insulation in homes is advocated. The expansion of renewable energy sources such as wind and water power is also suggested. Nuclear power is promoted as it reduces the carbon dioxide emissions and in both the short and long-term will reduce the emission of greenhouse gases. (author)

Paediatric surgery outreach: analysis of referrals to a tertiary paediatric surgery service to plan an outreach programme Kwa-Zulu Natal, South Africa.

Science.gov (United States)

Manickchund, Yashoda; Hadley, G P

2017-10-01

Paediatric surgical disease is a neglected health problem. Patients travel great distances to tertiary level care for management. This study aimed at analysing referral patterns to design an outreach programme for paediatric surgery in KwaZulu Natal. Data forms of patients referred to the service between January and July 2016 were correlated with the clinical record. Delays in management were compared to morbidity and mortality. Out of 781, 158 referrals were accepted as emergencies. The majority (62%) were children aged < 1 year. Gastro-intestinal problems (38.4%) and congenital anomalies (26.9%) formed the majority. Patients who died had a significantly longer delay in transfer. Longer total delay was associated with statistically significant greater morbidity. In a setting where a large rural population is served by single-centre tertiary care, delays exist and contribute to morbidity. The authors advocate the establishment of an outreach programme to address these issues.

Steps toward a cooler greenhouse

International Nuclear Information System (INIS)

Kerr, R.A.

1991-01-01

In April a committee of the National Academies of Science and Engineering and the Institute of Medicine urged the Bush Administration and Congress to begin cutting emissions of greenhouse gases immediately. The risk of delay is great, and the cost of insurance against disastrous climate warming is cheap. Now the committee's panel on mitigation has issued a 500-page report describing just how cheap that hedge against a climate calamity could be. The panel found that it would not be unreasonable to expect that a 25% reduction in US greenhouse gas emissions might be achieved at a cost of less than $10 per ton of carbon dioxide or its equivalent in other greenhouse gases. In more familiar terms, that considerable reduction in greenhouse emissions would cost about $4.75 for each barrel of oil burned or $0.11 per gallon of gasoline. The most cost-effective measures for reducing emissions, are increasing the energy efficiency of residential and commercial buildings and activities, vehicles, and industrial processes that use electricity

The Australian coal industry is actively involved in greenhouse gas emission management and abatement issues. An Australian Coal Association (ACA) position paper on greenhouse in November 1989, recommended a number of strategies to minimise the greenhouse effect, including the enhancement of energy utilisation efficiency, improved energy conversion efficiency at coal-fired power stations, expanded use of solar heating, and improved recycling. All of the strategies have been implemented to various degrees. The management and abatement of greenhouse gas emissions within the coal industry has been approached from an individual operational level, and a 'higher' industry level

A Modern Explorer's Journey - using events for innovative multipurpose educational outreach

Lilja Bye, Bente

2014-05-01

Earth observations are important across the specter of geo-sciences. The Group on Earth Observations (GEO) is coordinating efforts to build a Global Earth Observation System of Systems, or GEOSS. The lack of dedicated funding to support specific Science &Technology activities in support of GEOSS is one of the most important obstacles to engaging the Science &Technology communities in its implementation. Finding resources to outreach and capacity building is likewise a challenge. The continuation of GEO and GEOSS rely on political support which again is influenced by public opinions. The GEO Ministerial Summit in 2014 was an event that both needed visibility and represented an opportunity to mobilize the GEO community in producing outreach and educational material. Through the combined resources from two of GEO tasks in the GEO work plan, a multipurpose educational outreach project was planned and executed. This project addressed the following issues: How can the GEO community mobilize resources for its work plan projects in the Societal Benefit Area Water? How can we produce more educational and capacity building material? How can the GEO community support the GEO secretariat related to public relations (material and otherwise) Based on activities described in the GEO work plan, a showcase video and online campaign consisting on a series of webinars were developed and produced. The video and webinars were linked through a common reference: the water cycle. Various aspects of the water cycle ranging from general to more technical and scientific education were covered in the webinars, while the video called A Modern Explorer's Journey focused on story telling with a more emotional appeal. The video was presented to the Ministers at the GEO Ministerial Summit and distributed widely to the GEO community and through social media and articles (as embedded YouTube and more). A discussion of challenges and successes of this event-based educational outreach project will be

Full Text Available Abstract Background Bharatpur Eye Hospital in Chitwan District, a primarily agrarian setting in south-central Nepal, reduced the number of diagnostic screening and treatment (DST camps by one half (151 to 75 in an attempt to increase both the efficiency of its outreach program and the number of people that go directly to the hospital for service. The Hospital evaluated the two program models in terms of program costs, cataract surgical utilization, hospital direct payment and patient equity. Methods The study is a prospective, before and after, study of the impact of an alternate outreach model on cataract service utilization patterns and cost per outreach camp and cost per cataract surgery at Bharatpur Eye Hospital, comparing the service years July 2006 to June 2007, with July 2007 to June 2008. Study findings were based on routinely gathered hospital and outreach administrative data. Results The total cost of the DST camps decreased by approximately US$2000. The cost per camp increased from US$52 to $78 and the cost per cataract surgery decreased from US$ 3.80 to $3.20. The number of patients who went directly to the hospital, and paid for cataract surgery, increased from 432 (17% to 623 (25%. The total number of cataract surgical procedures at Bharatpur Eye Hospital remained very similar between the two service years (2501 and 2449, respectively. The presenting visual acuity and sex of the two cataract surgical populations were very similar (favouring women, 53 and 55% in the two years, respectively. A shift toward younger men and women occurred with a 245 (64% increase in people age 50-59 years, and shift away from people age 70 years and older with a 236 (22% reduction. The age and sex distribution of the direct paying patients were very similar in the two years. Conclusion The new, more concentrated, more rural DST model of service delivery reduced overall outreach program costs, cost per cataract surgery transported, while increasing

Per capita emissions of greenhouse gases and international trade

International Nuclear Information System (INIS)

Karman, D.; Baptiste, S.

1994-01-01

The role played by international trade in Canada's emissions of greenhouse gases is investigated. Data used in the study include Environment Canada greenhouse gas emission estimates for 1990, a Statistics Canada input-output model linking greenhouse gas emissions to economic activity in different sectors, and monetary statistics on imports and exports. Subject to some simplifying assumptions, it is estimated that nearly 20% of Canada's greenhouse gas emissions can be attributed to the production of commodities destined for export to other countries. If the same greenhouse gas emission intensities are assumed for Canada's imports, the greenhouse gas emissions due to Canada's net trade is nearly 7% of the 660 megatonnes of CO 2 equivalent emissions for 1990. Commodities from natural resource exploitation head the list of greenhouse gas emissions attributed to international trade, as expected from their large export volumes and large greenhouse gas emission intensities. 4 refs., 1 fig

2016-09-01

The Lightwave Roadshow is an outreach program run by research students at the University of Southampton, UK, that seeks to educate and inspire young students with optics, through conducting workshops in local schools and exhibiting at local and regional educational fairs. Adopting a hands-on philosophy enabled by an extensive collection of experimental optical demonstrations, Lightwave aims to promote scientific interest and indirectly address the global STEM skills shortage. While Lightwave has become a well-established program in local schools since its inception in 1998, 2015 included an unprecedented number of overseas activities. Inspired by the In- ternational Year of Light and Light-based Technologies (IYL 2015), Lightwave organized a school workshop in a foreign country (Singapore) as well as exhibited at major events, including the IYL 2015 opening ceremony in France, which marked the first time that the roadshow used UK school students to deliver outreach activities beyond the UK. These recent successful overseas projects have encouraged the outreach team to continue expand- ing the reach of the roadshow internationally. Of particular note is the involvement of Lightwave at academic conferences, where experiences and best practices can be shared among outreach ambassadors from different programs, student chapters, universities, and organizations. This paper provides a review of these activities, and identifies the administrative and practical challenges of bringing a local outreach program abroad and some strategies to overcome them. We also outline our travel suite of experimental demonstration kit, a portable selection from our main equipment inventory. This won the recent OSA `IYL-To-Go' student competition.

Sonic anemometry to measure natural ventilation in greenhouses.

Science.gov (United States)

López, Alejandro; Valera, Diego Luis; Molina-Aiz, Francisco

2011-01-01

The present work has developed a methodology for studying natural ventilation in Mediterranean greenhouses by means of sonic anemometry. In addition, specific calculation programmes have been designed to enable processing and analysis of the data recorded during the experiments. Sonic anemometry allows us to study the direction of the airflow at all the greenhouse vents. Knowing through which vents the air enters and leaves the greenhouse enables us to establish the airflow pattern of the greenhouse under natural ventilation conditions. In the greenhouse analysed in this work for Poniente wind (from the southwest), a roof vent designed to open towards the North (leeward) could allow a positive interaction between the wind and stack effects, improving the ventilation capacity of the greenhouse. The cooling effect produced by the mass of turbulent air oscillating between inside and outside the greenhouse at the side vents was limited to 2% (for high wind speed, u(o) ≥ 4 m s(-1)) reaching 36.3% when wind speed was lower (u(o) = 2 m s(-1)).

I have created and applied diverse methods in public outreach at National Autonomous Univerisity of Mexico (UNAM) since 2001.A student-led volunteer astronomical club has been created, the biggest in Mexico. We serve over 10,000 people per year. We have created public outreach activities for the general audience: archeo-astronomical outings, scientific movie debates, conferences, courses, public telescope viewings. We have also worked with juvenile delinquents to offer them scientific opportunities when released from jail.I've also created and worked the social media for the Institute of Astronomy UNAM, which is currently the biggest social media site on astronomy in Spanish in the world. I've created and organized a mass photo exhibition (over 1 million people served) for the Institute of Astronomy, UNAM which was citizen-funded through an online platform, the first of its kind in the country. Together with my colleages, we created workshops on astronomy for children with the Mexican's government funding.I've participated in several radio and television programs/capsules designed to bring astronomy to the general audience, one in particular ("Astrophysics for Dummies") was very successful in nation-wide Mexican radio.I am currently applying all experiences to develop a new public outreach project on astronomy for the University of California - Riverside and its on-campus and surrounding Latin American communities. We are offering new workshops for blind and deaf children. We want to integrate the Latino community to our outreach activities and offer science in their language in a simple and entertaining fashion. We have also successfully applied astrophotography as a course which brings social-science and arts undergraduate students into natural sciences.Sharing experiences, success and failure stories will help new and experienced educators and public outreach professionals learn and better from past experiences.

Effectiveness of OSHA Outreach Training on carpenters' work-related injury rates, Washington State 2000-2008.

Schoenfisch, Ashley L; Lipscomb, Hester; Sinyai, Clayton; Adams, Darrin

2017-01-01

Despite the size and breadth of OSHA's Outreach Training program for construction, information on its impact on work-related injury rates is limited. In a 9-year dynamic cohort of 17,106 union carpenters in Washington State, the effectiveness of OSHA Outreach Training on workers' compensation claims rate was explored. Injury rates were calculated by training status overall and by carpenters' demographic and work characteristics using Poisson regression. OSHA Outreach Training resulted in a 13% non-significant reduction in injury claims rates overall. The protective effect was more pronounced for carpenters in their apprenticeship years, drywall installers, and with increasing time since training. In line with these observed effects and prior research, it is unrealistic to expect OSHA Outreach Training alone to have large effects on union construction workers' injury rates. Standard construction industry practice should include hazard awareness and protection training, coupled with more efficient approaches to injury control. Am. J. Ind.

Jastrow, R.; Nierenberg, W.; Seitz, F.

1992-01-01

The spectre of major climate change caused by the greenhouse effect has generated intensive research, heated scientific debate and a concerted international effort to draft agreements for the reduction of greenhouse gas emissions. This report of Scientific Perspectives on the greenhouse problem explains the technical issues in the debate in language readily understandable to the non-specialist. The inherent complexities of attempts to simulate the earth's climate are explained, particularly with regard to the effects of clouds and the circulation of the oceans, which together represent the largest factors of uncertainty in current global warming forecasts. Results of the search for the 'greenhouse signal' in existing climate records aredescribed in chapter 3 (part two). Chapter 5 (part two) develops a projection of 21st-century warming based on relatively firm evidence of the earth's actual response to known increases in greenhouse gas emissions during the last 100 years

The International Heliophysical Year (IHY) in 2007 & 2008 will celebrate the 50th anniversary of the International Geophysical Year (IGY) and, following its tradition of international research collaboration, will focus on the cross-disciplinary studies of universal processes in the heliosphere. 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 how to participate in the IHY Education and Outreach Program and the benefits in doing so. Emphasis will be given to the role played by developing countries; not only in selecting useful resources and helping in their translation and adaptation, but also in providing different approaches and techniques in teaching.

The study shows the significant green-house advantage that natural gas appliances have over electric appliances. Findings from other studies also support this claim. The natural gas suppliers are encouraged to take advantage of the marketing opportunity that these studies provide, offering the householders the fuel that will significantly reduce their contribution to greenhouse emission

Energy use pattern analyses of greenhouse vegetable production

Energy Technology Data Exchange (ETDEWEB)

Canakci, M.; Akinci, I. [Department of Agricultural Machinery, Faculty of Agriculture, Akdeniz University, 07070 Antalya (Turkey)

2006-07-15

Greenhouse farming is a growing industry in many states. It is a very expensive way to produce greenhouse crops and there are many variables to consider before the farmer decides to take this route. A good location is essential for crop planning and growing. However, current studies related to energy use patterns and resources present in vegetable production are very limited. This research attempts to investigate the energy use patterns in greenhouse vegetable production, to determine the energy output-input ratio and their relationships. Antalya province, which has greenhouse area of about 13,337ha (30.2%), is the center of greenhouse farming in Turkey. A questionnaire was distributed to 101 greenhouse farms from 11 villages in order to obtain the available data for vegetable production. Power requirement of the machines used in greenhouse operations were measured by using a computer based data acquisition system. Energy and economical variables (i.e. output-input ratio, specific energy, production cost, net return, etc.) were calculated by using the standard equations. As a result, the operational energy and energy source requirements of the greenhouse vegetable production were found between the ranges of 23,883.5-28,034.7 and 45,763.3-49,978.8MJ/1000m{sup 2}, respectively. The energy ratio of four major greenhouse vegetables-tomato, pepper, cucumber and eggplant-was 0.32, 0.19, 0.31, 0.23, respectively. The crop yields increased as a function of the total energy inputs with the best form being second-degree polynomial. The net return of the vegetable production was found in the 595.6-2775.3$/1000m{sup 2} ranges. Among the greenhouse vegetables, tomato cultivation resulted in being the most profitable. (author)

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

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

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.

Low Simulated Radiation Limit for Runaway Greenhouse Climates

Science.gov (United States)

Goldblatt, Colin; Robinson, Tyler D.; Zahnle, Kevin J.; Crisp, David

2013-01-01

Terrestrial planet atmospheres must be in long-term radiation balance, with solar radiation absorbed matched by thermal radiation emitted. For hot moist atmospheres, however, there is an upper limit on the thermal emission which is decoupled from the surface temperature. If net absorbed solar radiation exceeds this limit the planet will heat uncontrollably, the so-called \\runaway greenhouse". Here we show that a runaway greenhouse induced steam atmosphere may be a stable state for a planet with the same amount of incident solar radiation as Earth has today, contrary to previous results. We have calculated the clear-sky radiation limits at line-by-line spectral resolution for the first time. The thermal radiation limit is lower than previously reported (282 W/sq m rather than 310W/sq m) and much more solar radiation would be absorbed (294W/sq m rather than 222W/sq m). Avoiding a runaway greenhouse under the present solar constant requires that the atmosphere is subsaturated with water, and that cloud albedo forcing exceeds cloud greenhouse forcing. Greenhouse warming could in theory trigger a runaway greenhouse but palaeoclimate comparisons suggest that foreseeable increases in greenhouse gases will be insufficient to do this.

Greenhouse gas emissions from hydroelectric reservoirs

International Nuclear Information System (INIS)

Rosa, L.P.; Schaeffer, R.

1994-01-01

In a recent paper, Rudd et al. have suggested that, per unit of electrical energy produced, greenhouse-gas emissions from some hydroelectric reservoirs in northern Canada may be comparable to emissions from fossil-fuelled power plants. The purpose of this comment is to elaborate these issues further so as to understand the potential contribution of hydroelectric reservoirs to the greenhouse effect. More than focusing on the total budget of carbon emissions (be they in the form of CH 4 or be they in the form of CO 2 ), this requires an evaluation of the accumulated greenhouse effect of gas emissions from hydroelectric reservoirs and fossil-fuelled power plants. Two issues will be considered: (a) global warming potential (GWP) for CH 4 ; and (b) how greenhouse-gas emissions from hydroelectric power plants stand against emissions from fossil-fuelled power plants with respect to global warming

Practices and promises of Facebook for science outreach: Becoming a "Nerd of Trust".

Science.gov (United States)

McClain, Craig R

2017-06-01

Arguably, the dissemination of science communication has recently entered a new age in which science must compete for public attention with fake news, alternate facts, and pseudoscience. This clash is particularly evident on social media. Facebook has taken a prime role in disseminating fake news, alternate facts, and pseudoscience, but is often ignored in the context of science outreach, especially among individual scientists. Based on new survey data, scientists appear in large Facebook networks but seldom post information about general science, their own scientific research, or culturally controversial topics in science. The typical individual scientist's audience is large and personally connected, potentially leading to both a broad and deep engagement in science. Moreover, this media values individual expertise, allowing scientists to serve as a "Nerd of Trust" for their online friend and family networks. Science outreach via social media demands a renewed interest, and Facebook may be an overlooked high-return, low-risk science outreach tool in which scientists can play a valuable role to combat disinformation.

Assessing the Impact of Peer Educator Outreach on the Likelihood and Acceleration of Clinic Utilization among Sex Workers.

Directory of Open Access Journals (Sweden)

Parthasarathy Krishnamurthy

Full Text Available Peer-led outreach is a critical element of HIV and STI-reduction interventions aimed at sex workers. We study the association between peer-led outreach to sex workers and the time to utilize health facilities for timely STI syndromic-detection and treatment. Using data on the timing of peer-outreach interventions and clinic visits, we utilize an Extended Cox model to assess whether peer educator outreach intensity is associated with accelerated clinic utilization among sex workers.Our data comes from 2705 female sex workers registered into Pragati, a women-in-sex-work outreach program, and followed from 2008 through 2012. We analyze this data using an Extended Cox model with the density of peer educator visits in a 30-day rolling window as the key predictor, while controlling for the sex workers' age, client volume, location of sex work, and education level. The principal outcome of interest is the timing of the first voluntary clinic utilization.More frequent peer visit is associated with earlier first clinic visit (HR: 1.83, 95% CI, 1.75-1.91, p < .001. In addition, 18% of all syndrome-based STI detected come from clinic visits in which the sex worker reports no symptoms, underscoring the importance of inducing clinic visits in the detection of STI. Additional models to test the robustness of these findings indicate consistent beneficial effect of peer educator outreach.Peer outreach density is associated with increased likelihood of-and shortened duration to-clinic utilization among female sex workers, suggesting potential staff resourcing implications. Given the observational nature of our study, however, these findings should be interpreted as an association rather than as a causal relationship.

Greenhouse effects on Venus

Bell, Peter M.

Calculations that used Pioneer-Venus measurements of atmosphere composition, temperature profiles, and radiative heating predicted Venus' surface temperature ‘very precisely,’ says the Ames Research Center. The calculations predict not only Venus' surface temperature but agree with temperatures measured at various altitudes above the surface by the four Pioneer Venus atmosphere probe craft.Using Pioneer-Venus spacecraft data, a research team has virtually proved that the searing 482° C surface temperature of Venus is due to an atmospheric greenhouse effect. Until now the Venus greenhouse effect has been largely a theory.

Energy market reform and greenhouse gas emission reductions

International Nuclear Information System (INIS)

Anon.

1999-01-01

The report reviews micro-economic reform in the energy market and measures the impact that energy market reform is expected to have on greenhouse gas outcomes. It indicates that reform in the electricity and gas industries is delivering what was promised, an efficient market with lower energy prices and, over the longer term, will deliver a gradually reducing rate of greenhouse gas emissions per unit of energy produced. It also recognises that energy market reform has removed some barriers to the entry of less greenhouse gas intense fuels. These trends will result in reduced greenhouse gas intensity in the supply of energy and significant reductions in the growth in greenhouse gas emissions compared to what may have been expected without the reforms

Scientists' internal models of the greenhouse effect

Libarkin, J. C.; Miller, H.; Thomas, S. R.

2013-12-01

A prior study utilized exploratory factor analysis to identify models underlying drawings of the greenhouse effect made by entering university freshmen. This analysis identified four archetype models of the greenhouse effect that appear within the college enrolling population. The current study collected drawings made by 144 geoscientists, from undergraduate geoscience majors through professionals. These participants scored highly on a standardized assessment of climate change understanding and expressed confidence in their understanding; many also indicated that they teach climate change in their courses. Although geoscientists held slightly more sophisticated greenhouse effect models than entering freshmen, very few held complete, explanatory models. As with freshmen, many scientists (44%) depict greenhouse gases in a layer in the atmosphere; 52% of participants depicted this or another layer as a physical barrier to escaping energy. In addition, 32% of participants indicated that incoming light from the Sun remains unchanged at Earth's surface, in alignment with a common model held by students. Finally, 3-20% of scientists depicted physical greenhouses, ozone, or holes in the atmosphere, all of which correspond to non-explanatory models commonly seen within students and represented in popular literature. For many scientists, incomplete models of the greenhouse effect are clearly enough to allow for reasoning about climate change. These data suggest that: 1) better representations about interdisciplinary concepts, such as the greenhouse effect, are needed for both scientist and public understanding; and 2) the scientific community needs to carefully consider how much understanding of a model is needed before necessary reasoning can occur.

Kuliasha, M.A.; Zucker, A.; Ballew, K.J.

1992-01-01

This conference explored how three technologies might help society adjust to life in a greenhouse-constrained environment. Technology experts and policy makers from around the world met June 11--13, 1991, in Oak Ridge, Tennessee, to address questions about how energy efficiency, biomass, and nuclear technologies can mitigate the greenhouse effect and to explore energy production and use in countries in various stages of development. The conference was organized by Oak Ridge National Laboratory and sponsored by the US Department of Energy. Energy efficiency biomass, and nuclear energy are potential substitutes for fossil fuels that might help slow or even reverse the global warming changes that may result from mankind's thirst for energy. Many other conferences have questioned whether the greenhouse effect is real and what reductions in greenhouse gas emissions might be necessary to avoid serious ecological consequences; this conference studied how these reductions might actually be achieved. For these conference proceedings, individuals papers are processed separately for the Energy Data Base

2009-12-01

The second Greenhouse Gas Information System (GHGIS) workshop was held May 20-22, 2009 at the Sandia National Laboratories in Albuquerque, New Mexico. The workshop brought together 74 representatives from 28 organizations including U.S. government agencies, national laboratories, and members of the academic community to address issues related to the understanding, operational monitoring, and tracking of greenhouse gas emissions and carbon offsets. The workshop was organized by an interagency collaboration between NASA centers, DOE laboratories, and NOAA. It was motivated by the perceived need for an integrated interagency, community-wide initiative to provide information about greenhouse gas sources and sinks at policy-relevant temporal and spatial scales in order to significantly enhance the ability of national and regional governments, industry, and private citizens to implement and evaluate effective climate change mitigation policies. This talk provides an overview of the second Greenhouse Gas Information System workshop, presents its key findings, and discusses current status and next steps in this interagency collaborative effort.

Using evaluation to adapt health information outreach to the complex environments of community-based organizations.

Science.gov (United States)

Olney, Cynthia A

2005-10-01

After arguing that most community-based organizations (CBOs) function as complex adaptive systems, this white paper describes the evaluation goals, questions, indicators, and methods most important at different stages of community-based health information outreach. This paper presents the basic characteristics of complex adaptive systems and argues that the typical CBO can be considered this type of system. It then presents evaluation as a tool for helping outreach teams adapt their outreach efforts to the CBO environment and thus maximize success. Finally, it describes the goals, questions, indicators, and methods most important or helpful at each stage of evaluation (community assessment, needs assessment and planning, process evaluation, and outcomes assessment). Literature from complex adaptive systems as applied to health care, business, and evaluation settings is presented. Evaluation models and applications, particularly those based on participatory approaches, are presented as methods for maximizing the effectiveness of evaluation in dynamic CBO environments. If one accepts that CBOs function as complex adaptive systems-characterized by dynamic relationships among many agents, influences, and forces-then effective evaluation at the stages of community assessment, needs assessment and planning, process evaluation, and outcomes assessment is critical to outreach success.

In order to achieve this mission, FEMP must send a clear message to everyone involved with the management of Federal facilities concerning its available resources, effective information and assistance, educational programs, tools, and training. To achieve this objective, American Ideas and Designs, Inc., d/b/a Greening America (hereinafter referred to as Recipient) has assisted FEMP in developing a comprehensive energy efficiency technology transfer program plan (hereinafter referred to as the outreach plan). A key component of the outreach plan involved the development and launch of a technology transfer campaign entitled ``You Have the Power.`` The outreach plan and the ``You Have the Power`` campaign emphasized the ability of individual Federal employees, Federal agencies, and stakeholder organizations to easily access FEMP`s energy efficiency tools and resources through a set of integrated interagency delivery programs.

The Sequestration Training, Outreach, Research and Education (STORE) Alliance at The University of Texas at Austin completed its activity under Department of Energy Funding (DE-FE0002254) on September 1, 2013. The program began as a partnership between the Institute for Geophysics, the Bureau of Economic Geology and the Petroleum and Geosystems Engineering Department at UT. The initial vision of the program was to promote better understanding of CO₂ utilization and storage science and engineering technology through programs and opportunities centered on training, outreach, research and technology transfer, and education. With over 8,000 hrs of formal training and education (and almost 4,500 of those hours awarded as continuing education credits) to almost 1,100 people, STORE programs and activities have provided benefits to the Carbon Storage Program of the Department of Energy by helping to build a skilled workforce for the future CCS and larger energy industry, and fostering scientific public literacy needed to continue the U.S. leadership position in climate change mitigation and energy technologies and application. Now in sustaining mode, the program is housed at the Center for Petroleum and Geosystems Engineering, and benefits from partnerships with the Gulf Coast Carbon Center, TOPCORP and other programs at the university receiving industry funding.

'Peak oil' or 'peak demand'?

Chevallier, Bruno; Moncomble, Jean-Eudes; Sigonney, Pierre; Vially, Rolland; Bosseboeuf, Didier; Chateau, Bertrand

2012-01-01

This article reports a workshop which addressed several energy issues like the objectives and constraints of energy mix scenarios, the differences between the approaches in different countries, the cost of new technologies implemented for this purposes, how these technologies will be developed and marketed, which will be the environmental and societal acceptability of these technical choices. Different aspects and issues have been more precisely presented and discussed: the peak oil, development of shale gases and their cost (will non conventional hydrocarbons modify the peak oil and be socially accepted?), energy efficiency (its benefits, its reality in France and other countries, its position in front of the challenge of energy transition), and strategies in the transport sector (challenges for mobility, evolution towards a model of sustainable mobility)

2018-01-01

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.

Automated Peak Picking and Peak Integration in Macromolecular NMR Spectra Using AUTOPSY

Science.gov (United States)

Koradi, Reto; Billeter, Martin; Engeli, Max; Güntert, Peter; Wüthrich, Kurt

1998-12-01

A new approach for automated peak picking of multidimensional protein NMR spectra with strong overlap is introduced, which makes use of the program AUTOPSY (automatedpeak picking for NMRspectroscopy). The main elements of this program are a novel function for local noise level calculation, the use of symmetry considerations, and the use of lineshapes extracted from well-separated peaks for resolving groups of strongly overlapping peaks. The algorithm generates peak lists with precise chemical shift and integral intensities, and a reliability measure for the recognition of each peak. The results of automated peak picking of NOESY spectra with AUTOPSY were tested in combination with the combined automated NOESY cross peak assignment and structure calculation routine NOAH implemented in the program DYANA. The quality of the resulting structures was found to be comparable with those from corresponding data obtained with manual peak picking.

Reflections on greenhouse gas life cycle assessment

International Nuclear Information System (INIS)

Jarrell, J.; Phillips, B.; Pendergast, D.

1999-01-01

The amount of carbon dioxide equivalent greenhouse gas emitted per unit of electricity produced is an important consideration in the planning of future greenhouse gas reduced electricity supply systems. Useful estimates of emissions must also take into account the entire cradle to grave life cycle emissions of alternative systems. Thus emissions of greenhouse gases take into account all of the components of building operating, and decommissioning facilities. This requires an accounting of emissions from production of all materials used to build the plants, transportation of materials to the site as well as fuels used for their construction, operation, and decommissioning. The construction of facilities may also have effects which tend to affect greenhouse gas emissions through modification of the local environment. A notable example, often cited, is the evolution of methane from the decay of organic matter submerged by dams built to serve hydro power facilities. In the long term, we anticipate that some kind of cost will be associated with the release of greenhouse gases. In that event it may be argued that the modified economic system established by inclusion of this cost will naturally control the emission of greenhouse gases from competing means of electricity production. Greenhouse gas emissions from all stages involved in the birth and retirement of electricity producing plant could be suitably constrained as the least cost method of production is sought. Such an ideal system is far from in place. At this point in time the results of life cycle accounting of greenhouse gas emissions are a needed means of comparing emissions from alternative sources of electricity. Many life cycle studies have been undertaken in the past. Many of the estimates are based on past practice which does not take into account any possible need to limit the production of greenhouse gas during the design of the plant and operational processes.

Stabilising the global greenhouse. A simulation model

International Nuclear Information System (INIS)

Michaelis, P.

1993-01-01

This paper investigates the economic implications of a comprehensive approach to greenhouse policies that strives to stabilise the atmospheric concentration of greenhouse gases at an ecolocially determined threshold level. In a theoretical optimisation model conditions for an efficient allocation of abatement effort among pollutants and over time are derived. The model is empirically specified and adapted to a dynamic Gams-algorithm. By various simulation runs for the period of 1990 to 2110, the economics of greenhouse gas accumulation are explored. In particular, the long-run cost associated with the above stabilisation target are evaluated for three different policy scenarios: i) A comprehensive approach that covers all major greenhouse gases simultaneously, ii) a piecemeal approach that is limited to reducing CO 2 emissions, and iii) a ten-year moratorium that postpones abatement effort until new scientific evidence on the greenhouse effect will become available. Comparing the simulation results suggests that a piecemeal approach would considerably increase total cost, whereas a ten-year moratorium might be reasonable even if the probability of 'good news' is comparatively small.

A Tale of Two scientists and their Involvement in Education & Outreach

Science.gov (United States)

McDonnell, J.

2004-12-01

Many scientists, when faced with developing an education and outreach plan for their research proposals, are unclear on what kinds of impacts they can have on broader non scientist audiences. Many scientists feel their only options are to develop a website or invite a teacher to get involved in their sampling or research cruises. Scientists, who are constrained by time and resources, are not aware of the range of education and outreach options available to them and of the great value their involvement can bring to the public. In an recent survey at the National Science Foundation sponsored ORION conference (January 2004), respondents stated that the greatest public benefits to having scientists involved in public education are (1) that they can present the benefits and relevance of research (26%), (2) focus awareness on environmental issues (26%), (3) serve as models for teachers and motivators for children (25%) and (4) increase public understanding, awareness and appreciation of science (about 22%). As a member of the Mid-Atlantic Center for Ocean Sciences Education Excellence (MACOSEE), the Institute of Marine & Coastal Sciences (IMCS) at Rutgers University is dedicated to helping scientists and educators realize the benefits of working together to advance ocean discovery and make known the vital role of the ocean in our lives. A website called "Scientist Connection" (www.macosee.net) was developed to help busy scientists choose a role in education and outreach that will make the most of their talent and time. The goal of the web site is to help scientists produce a worthwhile education project that complements and enriches their research. In this session, the author will present two case studies that demonstrate very different but effective approaches to scientist's involvement in education and outreach projects. In the first case, we will chronicle how a team of biologists and oceanographers in the Rutgers University, Coastal Ocean Observation Laboratory (or

Base-Load and Peak Electricity from a Combined Nuclear Heat and Fossil Combined-Cycle Plant

International Nuclear Information System (INIS)

Conklin, Jim; Forsberg, Charles W.

2007-01-01

A combined-cycle power plant is proposed that uses heat from a high-temperature reactor and fossil fuel to meet base-load and peak electrical demands. The high-temperature gas turbine produces shaft power to turn an electric generator. The hot exhaust is then fed to a heat recovery steam generator (HRSG) that provides steam to a steam turbine for added electrical power production. A simplified computational model of the thermal power conversion system was developed in order to parametrically investigate two different steady-state operation conditions: base load nuclear heat only from an Advanced High Temperature Reactor (AHTR), and combined nuclear heat with fossil heat to increase the turbine inlet temperature. These two cases bracket the expected range of power levels, where any intermediate power level can result during electrical load following. The computed results indicate that combined nuclear-fossil systems have the potential to offer both low-cost base-load electricity and lower-cost peak power relative to the existing combination of base-load nuclear plants and separate fossil-fired peak-electricity production units. In addition, electric grid stability, reduced greenhouse gases, and operational flexibility can also result with using the conventional technology presented here for the thermal power conversion system coupled with the AHTR

Almost two-thirds of the 110,000 people living with dementia in Switzerland receive home care from family members. Outreach counselling can reduce the burden for family caregivers and delay nursing home placement. However, little is known of how this works and how caregivers experience the counselling. The Canton of Aargau Alzheimer's Association has been conducting a pilot project to demonstrate the necessity, effectiveness and practicability of outreach counselling in (their canton). As a part of the evaluation of the project this study explored how family members experience the process of caring for a relative with dementia and outreach counselling. Interpretive phenomenology–a qualitative approach–was used to analyse data from interviews with twelve family caregivers. Most family members felt supported in caregiving by outreach counselling. Three aspects of the counselling were especially important to the participants: being understood and taken seriously by the counsellor; receiving answers to their most pressing questions concerning the illness and being supported when difficult decision had to be taken; regaining personal time and learning how to better interact with the person with dementia. Two participants would have wished for more help by the counsellor. To meet the needs of the family members, consultants should have sufficient experience in dementia patient care and should be strongly networked across the local health and welfare system. This study shows that family members can experience outreach counselling as a great support in their caregiving roles.

OBJECTIVES: The aim of this study was to investigate the possibility of subtoxic exposure to pesticides causing chromosome aberrations in greenhouse workers. METHODS: In a cross-sectional and prospective study design chromosome aberration frequencies in cultured lymphocytes were examined for 116...... greenhouse workers exposed to a complex mixture of almost 50 insecticides, fungicides, and growth regulators and also for 29 nonsmoking, nonpesticide-exposed referents. RESULTS: The preseason frequencies of chromosome aberrations were slightly but not statistically significantly elevated for the greenhouse...... workers when they were compared with the referents. After a summer season of pesticide spraying in the greenhouses, the total frequencies of cells with chromosome aberrations were significantly higher than in the preseason samples (P=0.02) and also higher than for the referents (P=0.05).

Practices and promises of Facebook for science outreach: Becoming a "Nerd of Trust".

Directory of Open Access Journals (Sweden)

Craig R McClain

2017-06-01

Full Text Available Arguably, the dissemination of science communication has recently entered a new age in which science must compete for public attention with fake news, alternate facts, and pseudoscience. This clash is particularly evident on social media. Facebook has taken a prime role in disseminating fake news, alternate facts, and pseudoscience, but is often ignored in the context of science outreach, especially among individual scientists. Based on new survey data, scientists appear in large Facebook networks but seldom post information about general science, their own scientific research, or culturally controversial topics in science. The typical individual scientist's audience is large and personally connected, potentially leading to both a broad and deep engagement in science. Moreover, this media values individual expertise, allowing scientists to serve as a "Nerd of Trust" for their online friend and family networks. Science outreach via social media demands a renewed interest, and Facebook may be an overlooked high-return, low-risk science outreach tool in which scientists can play a valuable role to combat disinformation.

This paper was originally presented at the 11th Pacific Basin Nuclear Conference, Banff, Alberta, Canada, May 3-7, 1998. It has been updated to include additional lifecycle data on chemical releases from ore treatment and CANDU fuel fabrication. It is sometimes stated that nuclear power plants can supply electricity with zero emissions of greenhouse gases. In fact, consideration of the entire fuel cycle indicates that some greenhouse gases are generated during their construction and decommissioning and by the preparation of fuel and other materials required for their operation. This follows from the use of fossil fuels in the preparation of materials and during the construction and decommissioning of the plants. This paper reviews life cycle studies of several different kinds of power plants. Greenhouse gases generated by fossil fuels during the preparation of fuel and heavy water used by operating CANDU power plants are estimated. The total greenhouse gas emissions from CANDU nuclear plants, per unit of electricity ultimately produced, are very small in comparison with emissions from most other types of power plants. (author)

Outdoor recreation can lead to substantial sun exposure. Employees of outdoor recreation establishments with extended time outdoors have amplified cumulative exposure to ultraviolet (UV) radiation and an increased risk of skin cancer. The "Sun Safe on the Slopes" program was created by Huntsman Cancer Institute at the University of Utah and the Utah Cancer Action Network to address increased UV exposure and skin cancer risk with free skin cancer screenings, outreach, and prevention education to local ski resorts. Herein, we describe the processes and barriers to implementation of a ski resort skin screening and education program and our 5-year report of the experience and screening data. Nine free skin cancer screenings were held at Utah ski resorts between 2011 and 2016, resulting in the presumptive diagnosis of 38 skin cancers (9.6%) in 394 participants. Behavioral data collected from participants indicates suboptimal sun safety practices, including underuse of sunscreen and protective clothing. Ski resort employees who experience sun exposure during peak hours at high altitudes and UV reflection from the snow are at an increased risk of skin cancer. These data indicate a need for emphasis on sun safety education and screening and can serve as a model for future endeavors.

1999-05-01

The Voluntary Reporting of Greenhouse Gases Program, required by Section 1605(b) of the Energy Policy Act of 1992, records the results of voluntary measures to reduce, avoid, or sequester greenhouse gas emissions. In 1998, 156 US companies and other organizations reported to the Energy information Administration that, during 1997, they had achieved greenhouse gas emission reductions and carbon sequestration equivalent to 166 million tons of carbon dioxide, or about 2.5% of total US emissions for the year. For the 1,229 emission reduction projects reported, reductions usually were measured by comparing an estimate of actual emissions with an estimate of what emissions would have been had the project not been implemented.

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.

The grant NAG-1 -2125, Technical Education Outreach in Materials Science and Technology, based on NASA s Materials Research, involves collaborative effort among the National Aeronautics and Space Administration s Langley Research Center (NASA-LaRC), Norfolk State University (NSU), national research centers, private industry, technical societies, colleges and universities. The collaboration aims to strengthen math, science and technology education by providing outreach related to materials science and technology (MST). The goal of the project is to transfer new developments from LaRC s Center for Excellence for Structures and Materials and other NASA materials research into technical education across the nation to provide educational outreach and strengthen technical education. To achieve this goal we are employing two main strategies: 1) development of the gateway website and 2) using the National Educators Workshop: Update in Engineering Materials, Science and Technology (NEW:Updates). We have also participated in a number of national projects, presented talks at technical meetings and published articles aimed at improving k-12 technical education. Through the three years of this project the NSU team developed the successful MST-Online site and continued to upgrade and update it as our limited resources permitted. Three annual NEW:Updates conducted from 2000 though 2002 overcame the challenges presented first by the September 11,2001 terrorist attacks and the slow U.S. economy and still managed to conduct very effective workshops and expand our outreach efforts. Plans began on NEW:Update 2003 to be hosted by NASA Langley as a part of the celebration of the Centennial of Controlled Flight.

Integration of Research Into Science-outreach (IRIS): A Video and Web-based Approach

Science.gov (United States)

Clay, P. L.; O'Driscoll, B.

2013-12-01

The development of the IRIS (Integration of Research Into Science-outreach) initiative is aimed at using field- and laboratory- based videos and blog entries to enable a sustained outreach relationship between university researchers and local classrooms. IRIS seeks to communicate complex, cutting-edge scientific research in the Earth and Planetary sciences to school-aged children in a simple and interesting manner, in the hope of ameliorating the overall decline of children entering into science and engineering fields in future generations. The primary method of delivery IRIS utilizes is the media of film, ';webinars' and blog entries. Filmed sequences of laboratory work, field work, science demos and mini webinars on current and relevant material in the Earth and Planetary sciences are ';subscribed' to by local schools. Selected sequences are delivered in 20-30 minute film segments with accompanying written material. The level at which the subject matter is currently geared is towards secondary level school-aged children, with the purpose of inspiring and encouraging curiosity, learning and development in scientific research. The video broadcasts are supplemented by a hands-on visit 1-2 times per year by a group of scientists participating in the filmed sequences to the subscribing class, with the objective of engaging and establishing a natural rapport between the class and the scientists that they see in the broadcasts. This transgresses boundaries that traditional 'one off' outreach platforms often aren't able to achieve. The initial results of the IRIS outreach initiative including successes, problems encountered and classroom feedback will be reported.

Clear Resin Casting of Arthropods of Medical Importance for Use in Educational and Outreach Activities

2018-01-01

Abstract Arthropod-related morbidity and mortality represent a major threat to human and animal health. An important component of reducing vector-borne diseases and injuries is training the next generation of medical entomologists and educating the public in proper identification of arthropods of medical importance. One challenge of student training and public outreach is achieving a safe mounting technique that allows observation of morphological characteristics, while minimizing damage to specimens that are often difficult to replace. Although resin-embedded specimens are available from commercial retailers, there is a need for a published protocol that allows entomologists to economically create high-quality resin-embedded arthropods for use in teaching and outreach activities. We developed a detailed protocol using readily obtained equipment and supplies for creating resin-embedded arthropods of many species for use in teaching and outreach activities. PMID:29718496

Economic Sustainability of Italian Greenhouse Cherry Tomato

Directory of Open Access Journals (Sweden)

Riccardo Testa

2014-11-01

Full Text Available Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, both from the perspective of the farm, as well as from that of the entrepreneur, the aim of this paper was to analyze the economic sustainability of Sicilian greenhouse cherry tomato cultivated in the Ragusa Province. In particular, an economic analysis on 30 representative farms was conducted in order to estimate production costs and profits of greenhouse cherry tomato. According to our results, the lack of commercial organization, which characterizes the small farms we surveyed, determines low contractual power for farmers and, consequently, low profitability.

As one of the hallmarks of agricultural modernization, intelligent greenhouse has the advantages of high yield, excellent quality, no pollution and continuous planting. Taking AT89S52 microcontroller as the main controller, the greenhouse intelligent control system uses soil moisture sensor, temperature and humidity sensors, light intensity sensor and CO2 concentration sensor to collect measurements and display them on the 12864 LCD screen real-time. Meantime, climate parameter values can be manually set online. The collected measured values are compared with the set standard values, and then the lighting, ventilation fans, warming lamps, water pumps and other facilities automatically start to adjust the climate such as light intensity, CO2 concentration, temperature, air humidity and soil moisture of the greenhouse parameter. So, the state of the environment in the greenhouse Stabilizes and the crop grows in a suitable environment.

Nitrous oxide (N 2 O) emissions from a typical greenhouse vegetable system in Northern China were measured from February 2004 to January 2006 using a close chamber method. Four nitrogen management levels (NN, MN, CN, and SN) were used. N 2 O emissions occurred intermittently in the growing season, strongly correlating with N fertilization and irrigation. No peak emissions were observed after fertilization in the late Autumn season due to low soil temperature. 57-94% of the seasonal N 2 O emissions came from the initial growth stage, corresponding to the rewetting process in the soil. The annual N 2 O emissions ranged from 2.6 to 8.8 kg N ha -1 yr -1 , accounting for 0.27-0.30% of the annual nitrogen input. Compared with conventional N management, site-specific N management reduced N fertilization rate by 69% in 2004 and by 76% in 2005, and consequently reduced N 2 O emissions by 51% in 2004 and 27% in 2005, respectively. - High N 2 O emissions coming from the initial growth stage can be attributed to the rewetting process in the greenhouse soil.

Many low- and middle-income countries (LMICs) have a high prevalence of unmet surgical need. Provision of operations through surgical outreach missions, mostly led by foreign organizations, offers a way to address the problem. We sought to assess the cost-effectiveness of surgical outreach missions provided by a wholly local organization in Ghana to highlight the role local groups might play in reducing the unmet surgical need of their communities. We calculated the disability-adjusted life years (DALY) averted by surgical outreach mission activities of ApriDec Medical Outreach Group (AMOG), a Ghanaian non-governmental organization. The total cost of their activities was also calculated. Conclusions about cost-effectiveness were made according to World Health Organization (WHO)-suggested parameters. We analyzed 2008 patients who had been operated upon by AMOG since December 2011. Operations performed included hernia repairs (824 patients, 41%) and excision biopsy of soft tissue masses (364 patients, 18%). More specialized operations included thyroidectomy (103 patients, 5.1%), urological procedures (including prostatectomy) (71 patients, 3.5%), and plastic surgery (26 patients, 1.3%). Total cost of the outreach trips was $283,762, and 2079 DALY were averted; cost per DALY averted was 136.49 USD. The mission trips were "very cost-effective" per WHO parameters. There was a trend toward a lower cost per DALY averted with subsequent outreach trips organized by AMOG. Our findings suggest that providing surgical services through wholly local surgical mission trips to underserved LMIC communities might represent a cost-effective and viable option for countries seeking to reduce the growing unmet surgical needs of their populations.

Fossil fuels provide the basis for world energy usage and, in the absence of fundamental policy changes, are expected to continue to do so for the next few decades. However, the prospect of global warming due to the greenhouse effect will have profound implications for the use of energy. This paper outlines the current situation and trends in world energy use, with a focus on energy requirements by region and fuel. Implications for greenhouse gas emissions and greenhouse policy challenges are also discussed. 8 refs., 1 tab., 2 figs

Ferrari, K.

2001-12-01

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.

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".

You Can't Flush Science Outreach

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.

The greenhouse challenge

International Nuclear Information System (INIS)

Harrington, Ph.

1999-01-01

At Kyoto, Australia was successful in gaining acceptance for a differentiated response to climate change which takes account of our special circumstances and allows for an 8% rise in emissions above 1990 levels by 2008 - 2012. This outcome is both environmentally effective but also responsible from the perspective of Australia's economic and trade interests. While our target is achievable it will require significant efforts on the part of industry, all levels of government and the wider community to move towards best practice in managing our greenhouse gas emissions. At the same time, it will provide an incentive for industry and businesses to further improve their efficiency and perhaps even to capture new opportunities that may present themselves. An outline of the National Greenhouse Strategy is given and some of the many implications for the minerals and energy sector are discussed

From the beginning of the HIV/AIDS epidemic, outreach workers have been on the frontlines of HIV prevention, working in community venues to increase knowledge and promote behaviors to reduce HIV transmission. As demographics of the HIV-infected population have changed, the need has grown to locate out-of-care individuals and learn how to engage and retain them in HIV care. Through the Health Resources and Services Administration (HRSA) Special Projects of National Significance (SPNS) Outreach Initiative, 10 sites across the United States implemented and evaluated enhanced outreach models designed to increase engagement and retention in HIV care for underserved, disadvantaged HIV-infected individuals. Although the models differed in response to local needs and organizational characteristics, all made use of a common conceptual framework, and all used the same data collection and reporting protocols. Study teams enrolled and provided behavioral interventions to HIV-infected individuals who have been noticeably absent from research and from practice. Their interventions incorporated coaching, skills-building, and education, and were successful in reducing or removing structural, financial, and personal/cultural barriers that interfered with equitable access to HIV care. Desired outcomes of increased engagement and retention in HIV health care were achieved. Results demonstrate that interventions to promote equitable access to HIV care for disadvantaged population groups can be built from outreach models. Qualitative and quantitative analysis of the multisite data indicates that further development and evaluation of outreach-based interventions will result in effective tools for reaching HIV-infected individuals who would otherwise remain without needed care.

Eduction and outreach for the global energy challenge

Science.gov (United States)

Snieder, R.

2008-12-01

Energy is the life-blood of the modern world. According to the Energy Information Administration, global energy consumption is expected to grow by about 70% in the coming 25 years. Much of this growth is driven by developing countries, whose inhabitants seek a standard of living that more closely resembles that of the western world. Petroleum provides about 40% of the world-wide energy demand, and, although estimates vary, oil production is expected to peak in the relatively near-future. The combination of increased energy demand and declining petroleum supply can be a threat to political stability and is likely to lead to a shift towards coal and non-conventional oil. This will further increase CO2 emissions and thus accelerate global warming and life-altering regional climate changes. Many actions can be taken now to begin to reduce energy demand, diversify our energy portfolio, and reduce costs of energy supplies, with lower greenhouse gas emissions. This will not happen, however, without a plan and the willingness to implement such a plan. Public engagement and education in dealing with the pressing challenges and opportunities are the key to getting started now. In order to foster such engagement I have prepared the presentation "The Global Energy Challenge." This Powerpoint presentation is freely available and aims to be appealing and understandable for a broad audience. The comment-boxes in the Powerpoint presentation give ideas for a narrative. The presentation sketches the tension between increased energy demand, peak oil, the associated challenge in curbing climate change, and actions that we can take towards a sustainable energy system. The presentation gives ideas for positive action that teachers, students, businessmen, consumers, and citizens can take, and it conveys that the challenges related to our energy supply come with career opportunities, a point that is especially appealing to a young audience. I invite to help making a difference by

The Space Science and Engineering Center (SSEC) and Cooperative Institute for Meteorological Satellite Studies (CIMSS) at the University of Wisconsin are now using a 3D spherical display system and their Man computer Data Access System (McIDAS)-X and McIDAS-V as outreach tools to demonstrate how scientists and forecasters utilize satellite imagery to monitor weather and climate. Our outreach program displays orbits and data coverage of geostationary and polar satellites and demonstrates how each is beneficial for the remote sensing of Earth. Global composites of visible, infrared and water vapor images illustrate how satellite instruments collect data from different bands of the electromagnetic spectrum to monitor global weather patterns 24 hours a day. Captivating animations on spherical display systems are proving to be much more intuitive than traditional 2D displays, enabling audiences to view satellites orbiting above real-time weather systems circulating the entire globe. Complimenting the 3D spherical display system are the UNIX-based McIDAS-X and Java-based McIDAS-V software packages. McIDAS is used to composite the real-time global satellite data and create other weather related derived products. Client and server techniques used by these software packages provide the opportunity to continually update the real-time content on our globe. The enhanced functionality of McIDAS-V extends our outreach program by allowing in-depth interactive 4-dimensional views of the imagery previously viewed on the 3D spherical display system. An important goal of our outreach program is the promotion of remote sensing research and technology at SSEC and CIMSS. The 3D spherical display system has quickly become a popular tool to convey societal benefits of these endeavors. Audiences of all ages instinctively relate to recent weather events which keeps them engaged in spherical display presentations. McIDAS facilitates further exploration of the science behind the weather

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). Universities, laboratories, and large collaboratives have responded by developing E/O programs that include interaction between students, teachers, and the public in schools; after-school and summer programs; and work through science centers, planetaria, aquaria, and museums.

The greenhouse effect - little strokes fell great oaks

It is a common assumption that carbon dioxide and other greenhouse gases constitute only a very small fraction of the atmosphere and thus cannot be as important as the climate researchers maintain. However, the adage of the title is appropriate for the impact of the greenhouse gases on the atmosphere. During the last 25 years, the global temperature has risen 0,5 o C, and during the last century by 0,75 o C. Thus according to the UN Climate Panel, there is evidence of a noticeable anthropogenic impact on the global climate. The article discusses the concept of greenhouse effect, the composition of the atmosphere, greenhouse gases and their importance, emission of carbon dioxide and natural climate changes

The aims of the US Department of Energy's Carbon Dioxide Research Program are to improve assessments of greenhouse-gas-induced climatic change and to define and reduce uncertainties through selected research. This project will address: The regional and seasonal details of the expected climatic changes; how rapidly will these changes occur; how and when will the climatic effects of CO 2 and other greenhouse gases be first detected; and the relationships between greenhouse-gas-induced climatic change and changes caused by other external and internal factors. The present project addresses all of these questions. Many of the diverse facets of greenhouse-gas-related climate research can be grouped under three interlinked subject areas: modeling, first detection and supporting data. This project will include the analysis of climate forcing factors, the development and refinement of transient response climate models, and the use of instrumental data in validating General Circulation Models (GCMs)

Multiagency Initiative to Provide Greenhouse Gas Information

Boland, Stacey W.; Duren, Riley M.

2009-11-01

Global Greenhouse Gas Information System Workshop; Albuquerque, New Mexico, 20-22 May 2009; The second Greenhouse Gas Information System (GHGIS) workshop brought together 74 representatives from 28 organizations including U.S. government agencies, national laboratories, and members of the academic community to address issues related to the understanding, operational monitoring, and tracking of greenhouse gas emissions and carbon offsets. The workshop was held at Sandia National Laboratories and organized by an interagency collaboration among NASA centers, Department of Energy laboratories, and the U.S. National Oceanic and Atmospheric Administration. It was motivated by the perceived need for an integrated interagency, community-wide initiative to provide information about greenhouse gas sources and sinks at policy-relevant temporal and spatial scales. Such an initiative could significantly enhance the ability of national and regional governments, industry, and private citizens to implement and evaluate effective climate change mitigation policies.

The greenhouse whitefly Trialeurodes vaporariorum (Hemiptera: Aleyrodidae) is a polyphagous pest in greenhouse crops. The efficacy of two entomopathogenic nematodes (EPN), Steinernema feltiae and Heterorhabditis bacteriophora, as biological control agents against T. vaporariorum was evaluated using two model crops typical of vegetable greenhouse productions: cucumber and pepper. Laboratory tests evaluated adults and second nymphal instars for pest susceptibility to different EPN species at different concentrations of infective juveniles (IJ; 0, 25, 50, 100, 150, 200, and 250 IJ per cm(2)); subsequent greenhouse trials against second nymphal instars on cucumber and pepper plants evaluated more natural conditions. Concentrations were applied in combination with Triton X-100 (0.1% v/v), an adjuvant for increasing nematode activity. In laboratory studies, both life stages were susceptible to infection by the two nematode species, but S. feltiae recorded a lower LC50 than H. bacteriophora for both insect stages. Similarly, in greenhouse experiments, S. feltiae required lower concentrations of IJ than H. bacteriophora to reach the same mortality in nymphs. In greenhouse trials, a significant difference was observed in the triple interaction among nematode species × concentration × plant. Furthermore, the highest mortality rate of the second nymphal instars of the T. vaporariorum was obtained from the application of S. feltiae concentrated to 250 IJ/cm(2) on cucumber (49 ± 1.23%). The general mortality caused by nematodes was significantly higher in cucumber than in pepper. These promising results support further investigation for the optimization of the best EPN species/concentration in combination with insecticides or adjuvants to reach a profitable control of this greenhouse pest.

The ocean plays an important role in the global processes of our planet, from climate change to sea level rise, uptake of carbon dioxide to fisheries stocks. In addition, its scientific importance, extraordinary beauty and public fascination provide perfect ingredients for both education and public outreach. Four years ago, after the launch of the "mon océan & moi" outreach project, an early career network (Ph.D. students and postdocs) has been formed to "promote collaborations/exchanges between the scientific and educational worlds in order to co-elaborate a teaching method for raising the awareness of school children on marine environments". Scientists are pursuing new research yielding improved knowledge and new documentation resources. However, they lack the communication skills to make the subject accessible to the general public. On the other hand, teachers must be informed of recent discoveries and of new resources for educational purposes. To fill this gap, the early career scientists developed, in collaboration with a school authority and an experienced science communicators team, both a trail education program tested directly in middle and high schools and innovative supporting material (i.e., animations, educative video clips and experiments, interactive maps and quizzes). Here we outline a set of guidelines as to how to improve science outreach across a variety of disciplines (e.g., science, technology, engineering) and how this may impact the experience of early career scientists. These tips will be useful for other early career scientists and science outreach projects, large or small, regional, national or international. Such novel outreach initiatives will help educate current and next generations about the importance of ocean environments and the relevance of ocean sciences for the society, and may serve as an example of teamwork for other young scientists.

As part of the CLE4R air quality education project, the University of Iowa has been working with AirBeam low-cost consumer-grade fine particulate matter (PM2.5) sensors in educational and outreach settings, both in K-12 environments and in informal settings such as science days and technology fairs. Users are attracted to the AirBeam device, in part, because of the easy creation of crowd-sourced maps of air pollution. With over 1000 AirBeam devices in use, extensive measurements are now available at aircasting.org. The AirBeam sensor is a portable, low-cost sensor which measures light scattering due to aerosols as a single bin converting the detected signal to a particle count and uses a calibration fit to estimate particle mass. The AirBeam is able to detect particle sizes of 0.5 - 2.5 µm, concentrations up to 400 µg m-3, and with a time resolution of 1 s. A corresponding Android device is used to visualize, record, and upload measured data to a community website (aircasting.org) that maps the spatial and temporal resolved data. The non-profit vendor's website constructs crowdsourced maps of air quality, environmental, and meteorological variables. As of April 1st, 2017, through the CLE4R project, 109 people had used the AirBeam sensors for educational purposes, for a total of 271 person hours. In the poster, we will explain the outreach that was done, and share best practices for education and outreach using consumer-grade PM sensors. Strengths and needed improvements to the technology for these outreach, education, and classroom uses will also be detailed. Sources of particles that can be artificially generated for educational use, including authentic smoke, spray smoke, and various dust sources will be enumerated. For use in K-12 classrooms, requirements for robust startup, operation, and ease-of-use are high. Mapping of concentrations is a desirable attribute but adds additional sources of failure to the hardware-software system used for education/outreach.

The use of solar energy for growing capsicums in pots and in the ground has been studied both under a controlled environment in a solar greenhouse (IIT model) and in an open field during August 2000 to March 2001. Cooling arrangements (natural, forced convection, shading, evaporative cooling) and heating methods (ground air collector, movable insulation during the night) have been employed during the pre-winter and winter periods respectively to maintain the protected environment in the greenhouse. The effects of a north brick wall and the use of movable insulation during the night in the winter months to reduce heat loss from the greenhouse have been incorporated to study the efficacy of the greenhouse. The average height, weight and yield per plant of the greenhouse crop were higher than those of the open field. (author)

The greenhouse effect: A new source of energy

International Nuclear Information System (INIS)

Meunier, Francis

2007-01-01

Climate change induced by global warming is a result of an excess of energy at the earth's surface due to the greenhouse effect. But a new energy management can reverse the situation taking advantage of the greenhouse effect to produce renewable energy. In fact, both the renewable energy and the energy consumed which are not dissipated into heat are subtracted from the excess of energy produced by the greenhouse effect and contribute to mitigate climate change. This opens perspectives to harness the greenhouse effect [F. Meunier, Domestiquer l'effet de serre, Dunod, 2005]. Should all the primary energy be renewable energy and should part of the energy production not dissipated into heat, the present earth's energy imbalance should be beneficial and should serve to produce renewable energy

Optical Science Discovery Program: Pre-College Outreach and So Much More

Deutsch, Miriam

2010-03-01

Recruiting and retaining women into the physical sciences is an ongoing struggle for universities, with the gap between men and women in physics remaining strong. Research shows a precipitous drop in female participation in the physical sciences around the 7th grade year of primary education, where girls begin losing interest during middle school, the drain continuing throughout high school with another significant drop at the bachelors level. To combat the loss of women in the physical sciences, the Oregon Center for Optics at the University of Oregon has created the Optical Science Discovery Program (OSDP), a precollege outreach program that targets girls in middle and high school. This program uses optical sciences as the medium through which girls explore experimental science. The program consists of a one-week intensive summer camp, a mentored monthly science club, summer internships and mentoring opportunities for camp alumni. By utilizing media often at the core of teenage life (e.g. Facebook, MySpace) we also aim to interact with program participants in a familiar and informal environment. Mentoring of OSDP activities is carried out by faculty and students of all levels. This in turn allows other education and outreach efforts at the University of Oregon to incorporate OSDP activities into their own, contributing to our broader university goals of surmounting barriers to higher education and creating a more scientifically literate populace. This talk will describe the OSDP program and its incorporation into the broader spectrum of outreach and education efforts.

A cost analysis of a hospital-based palliative care outreach program: implications for expanding public sector palliative care in South Africa.

Science.gov (United States)

Hongoro, Charles; Dinat, Natalya

2011-06-01

Increasing access to palliative care services in low- and middle-income countries is often perceived as unaffordable despite the growing need for such services because of the increasing burden of chronic diseases including HIV and AIDS. The aim of the study was to establish the costs and cost drivers for a hospital outreach palliative care service in a low-resource setting, and to elucidate possible consequential quality-of-life improvements and potential cost savings. The study used a cost accounting procedure to cost the hospital outreach services--using a step-down costing method to measure unit (average) costs. The African Palliative Care Association Palliative Outcome Score (APCA POS) was applied at five intervals to a cohort of 72 consecutive and consenting patients, enrolled in a two-month period. The study found that of the 481 and 1902 patients registered for outreach and in-hospital visits, respectively, 4493 outreach hospital visits and 3412 in-hospital visits were done per year. The costs per hospital outreach visit and in-hospital visit were US$71 and US$80, respectively. The cost per outreach visit was 50% less than the average cost of a patient day equivalent for district hospitals of $142. Some of the POS of a subsample (n=72) showed statistically significant improvements. Hospital outreach services have the potential to avert hospital admissions in generally overcrowded services in low-resource settings and may improve the quality of life of patients in their home environments.

Practices and promises of Facebook for science outreach: Becoming a “Nerd of Trust”

Science.gov (United States)

2017-01-01

Arguably, the dissemination of science communication has recently entered a new age in which science must compete for public attention with fake news, alternate facts, and pseudoscience. This clash is particularly evident on social media. Facebook has taken a prime role in disseminating fake news, alternate facts, and pseudoscience, but is often ignored in the context of science outreach, especially among individual scientists. Based on new survey data, scientists appear in large Facebook networks but seldom post information about general science, their own scientific research, or culturally controversial topics in science. The typical individual scientist’s audience is large and personally connected, potentially leading to both a broad and deep engagement in science. Moreover, this media values individual expertise, allowing scientists to serve as a “Nerd of Trust” for their online friend and family networks. Science outreach via social media demands a renewed interest, and Facebook may be an overlooked high-return, low-risk science outreach tool in which scientists can play a valuable role to combat disinformation.

Build Your Own Particle Detector. Education and outreach through ATLAS LEGO models and events

CERN Document Server

AUTHOR|(INSPIRE)INSPIRE-00220289; The ATLAS collaboration

2016-01-01

To support the outreach activities of ATLAS institutes and to grasp people’s attention in science exhibitions and during public events, a very detailed model of the experiment built entirely out of LEGO bricks as well as an outreach programme using LEGO bricks to get people to think about particle detectors and involve them into a conversation about particle physics in general have been created. A large LEGO model, consisting of about 9500 pieces, has been exported to more than 55 ATLAS institutes and has been used in numerous exhibitions to explain the proportion and composition of the experiment to the public. As part of the Build Your Own Particle Detector programme (byopd.org) more than 15 events have been conducted, either involving a competition to design and build the best particle detector from a random pile of pieces or to take part in the construction of one of the large models, as part of a full day outreach event. Recently, miniature models of all four main LHC experiments, that will be used at ...

The paper tools used to monitor outreach work in all major cities in Viet Nam had substantial writing requirements for each contact with difficulty maintaining confidentiality. This paper describes the development of a Unique Identifier Code (UIC), a field data collection notebook (databook) and a computer data entry system in Viet Nam. The databook can document 40 individual clients and has space for commodity distribution, group contacts and needles/syringe collection for each month. Field implementation trials of the UIC and databook have been undertaken by more than 160 peer outreach workers to document their work with people who inject drugs (PWID) and sex workers (SW). Following an expanded trial in Hai Phong province, there have been requests for national circulation of the databook to be used by peer educators documenting outreach to PWID, SW and men who have sex with men. The standardized UIC and databook, in a variety of locally adapted formats, have now been introduced in more than 40 of the 63 provinces in Viet Nam. This development in Viet Nam is, to our knowledge, the first example of the combination of a confidential UIC and an innovative, simple pocket-sized paper instrument with associated customized data-entry software for documenting outreach.

2016-02-01

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.

2015-10-01

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.

The greenhouse and antigreenhouse effects on Titan

Science.gov (United States)

Mckay, Christopher P.; Pollack, James B.; Courtin, Regis

1991-01-01

The parallels between the atmospheric thermal structure of the Saturnian satellite Titan and the hypothesized terrestrial greenhouse effect can serve as bases for the evaluation of competing greenhouse theories. Attention is presently drawn to the similarity between the roles of H2 and CH4 on Titan and CO2 and H2O on earth. Titan also has an antigreenhouse effect due to a high-altitude haze layer which absorbs at solar wavelengths, while remaining transparent in the thermal IR; if this haze layer were removed, the antigreenhouse effect would be greatly reduced, exacerbating the greenhouse effect and raising surface temperature by over 20 K.

Effects of simplifying outreach materials for energy conservation programs that target low-income consumers

International Nuclear Information System (INIS)

Wong-Parodi, Gabrielle; Bruine de Bruin, Wändi; Canfield, Casey

2013-01-01

Critics have speculated that the limited success of energy conservation programs among low-income consumers may partly be due to recipients having insufficient literacy to understand the outreach materials. Indeed, we found outreach materials for low-income consumers to require relatively high levels of reading comprehension. We therefore improved the Flesch–Kincaid readability statistics for two outreach brochures, by using shorter words and shorter sentences to describe their content. We examined the effect of that simplification on low-income consumers′ responses. Participants from low-income communities in the greater Pittsburgh area, who varied in literacy, were randomly assigned to either original communications about energy conservation programs or our simplified versions. Our findings suggest that lowering readability statistics successfully simplified only the more straightforward brochure in our set of two, likely because its content lent itself better to simplification. Findings for this brochure showed that simplification improved understanding of its content among both low-literacy and high-literacy recipients, without adversely affecting their evaluation of the materials, or their intention to enroll in the advertised programs. We discuss strategies for improving communication materials that aim to reach out to low-income populations. - Highlights: • Brochures about energy programs for low-income consumers can be too hard to read. • We made brochures easier to read by using shorter words and shorter sentences. • Simplifying a straightforward brochure improved the understanding of all recipients. • However, simplifying a complex brochure had no effect on understanding. • We suggest strategies for improving outreach to low-income consumers

Policy and Environmental Implications of Photovoltaic Systems in Farming in Southeast Spain: Can Greenhouses Reduce the Greenhouse Effect?

Directory of Open Access Journals (Sweden)

Angel Carreño-Ortega

2017-05-01

Full Text Available Solar photovoltaic (PV systems have grown in popularity in the farming sector, primarily because land area and farm structures themselves, such as greenhouses, can be exploited for this purpose, and, moreover, because farms tend to be located in rural areas far from energy production plants. In Spain, despite being a country with enormous potential for this renewable energy source, little is being done to exploit it, and policies of recent years have even restricted its implementation. These factors constitute an obstacle, both for achieving environmental commitments and for socioeconomic development. This study proposes the installation of PV systems on greenhouses in southeast Spain, the location with the highest concentration of greenhouses in Europe. Following a sensitivity analysis, it is estimated that the utilization of this technology in the self-consumption scenario at farm level produces increased profitability for farms, which can range from 0.88% (worst scenario to 52.78% (most favorable scenario. Regarding the Spanish environmental policy, the results obtained demonstrate that the impact of applying this technology mounted on greenhouses would bring the country 38% closer to reaching the 2030 greenhouse gas (GHG target. Furthermore, it would make it possible to nearly achieve the official commitment of 20% renewable energies by 2020. Additionally, it would have considerable effects on the regional socioeconomy, with increases in job creation and contribution to gross domestic product (GDP/R&D (Research and Development, allowing greater profitability in agrifood activities throughout the entire region.

1995-11-01

Greenhouse gas research programs and projects that relate to the Canadian natural gas industry were presented. Fossil fuel related emissions, primarily methane and carbon dioxide, impact on the atmospheric concentrations of the greenhouse gases. Therefore, strategies to reduce these emissions should impact on the Canadian natural gas industry. A list of 39 projects and 18 research programs of potential interest to the natural gas industry were presented in summary form. The involvement of CANMET (Canada Centre for Mineral and Energy Technology), Environment Canada, and NSERC (Natural Sciences and Engineering Research Council) in doing or sponsoring research projects directed towards greenhouse gas emission reduction was highlighted. Some potential options for member companies of the Canadian natural gas industry, to support climate change and greenhouse gas research, were outlined. 6 refs., 12 tabs

Climate change induced by global warming is a result of an excess of energy at the earth's surface due to the greenhouse effect. But a new energy management can reverse the situation taking advantage of the greenhouse effect to produce renewable energy. In fact, both the renewable energy and the energy consumed which are not dissipated into heat are subtracted from the excess of energy produced by the greenhouse effect and contribute to mitigate climate change. This opens perspectives to harness the greenhouse effect [F. Meunier, Domestiquer l'effet de serre, Dunod, 2005]. Should all the primary energy be renewable energy and should part of the energy production not dissipated into heat, the present earth's energy imbalance should be beneficial and should serve to produce renewable energy.

Peak regulation right

International Nuclear Information System (INIS)

Gao, Z. |; Ren, Z.; Li, Z.; Zhu, R.

2005-01-01

A peak regulation right concept and corresponding transaction mechanism for an electricity market was presented. The market was based on a power pool and independent system operator (ISO) model. Peak regulation right (PRR) was defined as a downward regulation capacity purchase option which allowed PRR owners to buy certain quantities of peak regulation capacity (PRC) at a specific price during a specified period from suppliers. The PRR owner also had the right to decide whether or not they would buy PRC from suppliers. It was the power pool's responsibility to provide competitive and fair peak regulation trading markets to participants. The introduction of PRR allowed for unit capacity regulation. The PRR and PRC were rated by the supplier, and transactions proceeded through a bidding process. PRR suppliers obtained profits by selling PRR and PRC, and obtained downward regulation fees regardless of whether purchases are made. It was concluded that the peak regulation mechanism reduced the total cost of the generating system and increased the social surplus. 6 refs., 1 tab., 3 figs

Comparing greenhouse gases for policy purposes

International Nuclear Information System (INIS)

Schmalensee, R.

1993-01-01

In order to derive optimal policies for greenhouse gas emissions control, the discounted marginal damages of emissions from different gases must be compared. The greenhouse warming potential (GWP) index, which is most often used to compare greenhouse gases, is not based on such a damage comparison. This essay presents assumptions under which ratios of gas-specific discounted marginal damages reduce to ratios of discounted marginal contributions to radiative forcing, where the discount rate is the difference between the discount rate relevant to climate-related damages and the rate of growth of marginal climate-related damages over time. If there are important gas-specific costs or benefits not tied to radiative forcing, however, such as direct effects of carbon dioxide on plant growth, there is in general no shortcut around explicit comparison of discounted net marginal damages. 16 refs

Greenhouse effects of aircraft emissions

Fortuin, J.P.F.; Wauben, W.M.F.; Dorland, R. van; Kelder, H.

1996-01-01

Ranges for direct and indirect greenhouse effects due to present day aircraft emissions are quantified for northern midlatitudes, using the concept of fixed temperature (FT) radiative forcing as calculated with a radiative transfer model. The direct greenhouse effects considered here are from emissions of carbon dioxide, water vapor, and nitrogen dioxide. To calculate the concentration increases of carbon dioxide and stratospheric water vapor, an analytical expression is developed based on a linear approximation of global fuel burn versus time. Unlike the expressions currently used in the literature, the authors' expression does not account for emission rates only, but also for a loss term--hence making it more suitable for shorter lived emittants. For midlatitude summer conditions, a total radiative forcing ranging from 0.04 to 0.09 Wm -2 is calculated for the direct greenhouse effects, whereas for midlatitude winter the range is 0.07 to 0.26 Wm -2 . The indirect greenhouse effects considered here are sulfate aerosol formation from sulfur dioxide emissions, contrail formation from emitted water vapor and condensation nuclei, and ozone formation from NO x emissions. The total radiative forcing coming from these indirect effects range from -0.67 to 0.25 Wm -2 in summer a/nd from -0.36 to 0.21 Wm -2 in winter. Further, the global distribution of NO x and ozone increases from aircraft emissions world-wide are simulated with a three-dimensional chemistry transport model for January and July. The geographical distribution of the radiative forcing associated with the simulated ozone increases is also calculated for these months

Lachowsky, Nathan J; Georgievski, Georgi; Rosser, Brian R Simon; MacLachlan, Duncan; Murray, James

2015-01-01

Background Men who use the Internet to seek sex with other men (MISM) are increasingly using the Internet to find sexual health information and to seek sexual partners, with some research suggesting HIV transmission is associated with sexual partnering online. Aiming to “meet men where they are at,” some AIDS service organizations (ASOs) deliver online outreach services via sociosexual Internet sites and mobile apps. Objective To investigate MISM's experiences and self-perceived impacts of online outreach. Methods From December 2013 to January 2014, MISM aged 16 years or older were recruited from Internet sites, mobile apps, and ASOs across Ontario to complete a 15-minute anonymous online questionnaire regarding their experience of online outreach. Demographic factors associated with encountering online outreach were assessed using backward-stepwise multivariable logistic regression (Ponline outreach services. Encountering online outreach was more likely for Aboriginal versus white MISM, MISM from Toronto compared with MISM from either Eastern or Southwestern Ontario, and MISM receiving any social assistance. MISM who experienced online outreach felt the service provider was friendly (130/141, 92.2%), easy to understand (122/140, 87.1%), helpful (115/139, 82.7%), prompt (107/143, 74.8%), and knowledgeable (92/134, 68.7%); half reported they received a useful referral (49/98, 50%). Few MISM felt the interaction was annoying (13/141, 9.2%) or confusing (18/142, 12.7%). As a result of their last online outreach encounter, MISM reported the following: better understanding of (88/147, 59.9%) and comfort with (75/147, 51.0%) their level of sexual risk; increased knowledge (71/147, 48.3%); and feeling less anxious (51/147, 34.7%), better connected (46/147, 31.3%), and more empowered (40/147, 27.2%). Behaviorally, they reported using condoms more frequently (48/147, 32.7%) and effectively (35/147, 23.8%); getting tested for HIV (43/125, 34.4%) or STIs (42/147, 28

The ATLAS experiment at the Large Hadron Collider at CERN has a substantial collaborative Education and Outreach project. This article describes its activities and how it promotes physics to students around the world. With the extraordinary possibility to make groundbreaking discoveries, the ATLAS Experiment [1] at the Large Hadron Collider at CERN can play an important role in promoting contemporary physics at school. For many years ATLAS has had a substantial collaborative Education and Outreach (E and O) project in which physicists from various parts of the world take part. When the experiment begins in 2007, students from around the world will be analyzing data using cutting-edge technology. The unprecedented collision energies of the Large Hadron Collider allow ATLAS to decode the 'events' that unfold after the head-on collisions of protons (Fig. 1). The scientific results from these events will reveal much about the basic nature of matter, energy, space, and time. Students and others will be excited as they try to find events that may be signs for dark matter, extra dimensions of space, mini-black holes, string theory, and other fundamental discoveries. Science education and outreach and the promotion of awareness and appreciation of physics research have become important tasks for the research community and should be recognized as a natural and logical part of science research and as an important link between research and society. To be successful these activities have to be done in a systematic and professional way. Leading scientists together with multimedia experts can form a powerful team with teachers and educators in disseminating physics information to school and universities. The ATLAS collaboration has fully recognized the importance of education and outreach. The ATLAS E and O project can be a model for today's large science experiments in promoting science at schools and universities

Universities in the United Kingdom have been driven to work with a larger pool of potential students than just the more traditional student (middle-class white male), in order to tackle the widely-accepted skills-shortage in the fields of science, technology, engineering and mathematics (STEM), whilst honoring their commitment to fair access to higher education. Student-led outreach programs have contributed significantly to this drive. Two such programs run by postgraduate students at the University of Southampton are the Lightwave Roadshow and Southampton Accelerate!, which focus on photonics and particle physics, respectively. The program ambassadors have developed activities to enhance areas of the national curriculum through presenting fundamental physical sciences and their applications to optics and photonics research. The activities have benefitted significantly from investment from international organizations, such as SPIE, OSA and the IEEE Photonics Society, and UK research councils, in conjunction with university recruitment and outreach strategies. New partnerships have been formed to expand outreach programs to work in non-traditional environments to challenge stereotypes of scientists. This paper presents two case studies of collaboration with education learning centers at Salisbury Cathedral and Winchester Cathedral. The paper outlines workshops and shows developed for pupils aged 6-14 years (UK key stages 2-4) on the electromagnetic spectrum, particle physics, telecommunications and the human eye using a combination of readily obtainable items, hand-built kits and elements from the EYEST Photonics Explorer kit. The activities are interactive to stimulate learning through active participation, complement the UK national curriculum and link the themes of science with the non-traditional setting of a cathedral. We present methods to evaluate the impact of the activity and tools to obtain qualitative feedback for continual program improvement. We also

For many years ATLAS has had a substantial collaborative Education and Outreach (E&O) project in which physicists from various parts of the world take part. When the experiment begins in 2007, students from around the world will be analyzing data using cutting-edge technology. The unprecedented collision energies of the Large Hadron Collider allow ATLAS to decode the 'events' that unfold after the head-on collisions of protons (Fig. 1). The scientific results from these events will reveal much about the basic nature of matter, energy, space, and time. Students and others will be excited as they try to find events that may be signs for dark matter, extra dimensions of space, mini-black holes, string theory, and other fundamental discoveries. Science education and outreach and the promotion of awareness and appreciation of physics research have become important tasks for the research community and should be recognized as a natural and logical part of science research and as an important link between research and society. To be successful these activities have to be done in a systematic and professional way. Leading scientists together with multimedia experts can form a powerful team with teachers and educators in disseminating physics information to school and universities. The ATLAS collaboration has fully recognized the importance of education and outreach. The ATLAS E&O project can be a model for today's large science experiments in promoting science at schools and universities.

CLEAR PM: Teaching, Outreach, and Research Through Real-Time Particulate Measurements

Science.gov (United States)

DeCarlo, P. F.

2013-12-01

An understanding of particulate matter (also called aerosols) can be made through measurement. This measurement does not change in value if it is made in a teaching, research, or outreach environment. A grant from the Camille and Henry Dreyfus Foundation provided funding to construct an instrument suite composed of 1-4 second measurements that are displayed in real-time through a software interface. This display module is called CLEAR PM (Chemistry Lessons Enabling Aerosol Realizations through Particulate Measurement), and was conceived to apply across outreach activities, teaching activities, and research activities. The construction and software design of CLEAR PM was done as part of a special topics course for chemistry and engineering graduate students at Drexel University. Measurement principles of the different (research grade) instruments were taught as part of the course, with emphasis put on the fundamental measurements and their limitations, and an introduction to data acquisition software was also integral to the teaching component. As a final project of the course graduate students were required to create a 'teaching' module that illustrates a chemistry or physics concept and utilizes the measurements of CLEAR PM. These modules ranged from gas-phase ozone chemistry creating secondary organic aerosols, to the wavelength dependent absorption profiles of wood smoke versus propane soot. The teaching modules developed by the graduate students have been used in outreach activities sponsored by The Franklin Institute and the Clean Air Council in Philadelphia, where underrepresented groups often make up a large fraction of the audience. CLEAR PM is designed to give students and citizens a hands-on opportunity to see how we measure and understand the world around us. As mentioned previously, the instruments that are part of CLEAR PM are research grade instruments, and are actively being used in research projects in the DeCarlo lab at Drexel to study particulate

1998-01-01

Since 1997, when the Australian Coal Association (ACA) signed a letter of Intent in respect of the governments Greenhouse Challenge Program, it has encouraged its member companies to participate. Earlier this year, the ACA commissioned an independent scoping study on greenhouse gas emissions in the black coal mining industry This was to provide background information, including identification of information gaps and R and D needs, to guide the formulation of a strategy for the mitigation of greenhouse gas emissions associated with the mining, processing and handling of black coals in Australia. A first step in the process of reducing emission levels is an appreciation of the source, quantity and type of emissions om nine sites. It is shown that greenhouse gas emissions on mine sites come from five sources: energy consumption during mining activities, the coal seam gas liberated due to the extraction process i.e. fugitive emissions, oxidation of carbonaceous wastes, land use, and embodied energy. Also listed are indications of the degree of uncertainty associated with each of the estimates

Greenhouse gas balances of biomass energy systems

International Nuclear Information System (INIS)

Marland, G.; Schlamadinger, B.

1996-01-01

A full energy-cycle analysis of greenhouse gas emissions of biomass energy systems requires analysis well beyond the energy sector. For example, production of biomass fuels impacts on the global carbon cycle by altering the amount of carbon stored in the biosphere and often by producing a stream of by-products or co-products which substitute for other energy-intensive products like cement, steel, concrete or, in case of ethanol form corn, animal feed. It is necessary to distinguish between greenhouse gas emissions associated with the energy product as opposed to those associated with other products. Production of biomass fuels also has an opportunity cost because it uses large land areas which could have been used otherwise. Accounting for the greenhouse gas emissions from biomass fuels in an environment of credits and debits creates additional challenges because there are large non-linearities in carbon flows over time. This paper presents some of the technical challenges of comprehensive greenhouse gas accounting and distinguishes between technical and public policy issues. (author). 5 refs, 5 figs

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.

Offsets : An innovative approach to reducing greenhouse gases

International Nuclear Information System (INIS)

Steward, B.

1998-01-01

One of the most innovative ways to address climate change is the use of offsets, which refers to actions taken outside of a company's operations, domestically and internationally, to reduce greenhouse gas emissions. This paper is devoted to a discussion of Suncor Energy's action plan for greenhouse gases which include offsets, and to an explanation of the reasons why offsets are fundamental to successful greenhouse gas management. Suncor Energy Inc., has developed a plan with seven elements to meet their target of stabilizing their greenhouse gas emissions at 1990 levels by year 2000. The seven elements include: (1) energy efficiency and process improvements at their oil sands facility, (2) the development of alternative and renewable sources of energy, such as ethanol blended gasolines and the use of wind turbines to generate electricity, (3) promoting environmental and economic research to develop more advanced oil and gas technology to reduce greenhouse gas emissions, (4) implementing a constructive public policy input in support of sustainable development, (5) educating employees, customers and communities on global climate change, (6) measuring and reporting the company's environmental progress, and (7) pursuing domestic and international offset opportunities such as transfer of technology to developing countries, cogeneration of energy using natural gas, energy efficiency, renewable energy sources, emission reduction purchases and forest conservation. Of these proposed measures, offsets are the critical element which could spell the difference between success and failure in managing greenhouse gas emissions and the difference between economic hardship and economic opportunity

Coal and the greenhouse effect: strategies for the future

Energy Technology Data Exchange (ETDEWEB)

Sullivan, K M [Australian Coal Association, Sydney, NSW (Australia)

1991-07-01

A number of gases, including carbon dioxide, methane, water vapour, nitrous oxide, ozone and chlorofluorocarbons are transparent to incoming short-wave radiation, but are relatively opaque to outgoing longwave radiation. Variations in the concentration of these gases in the troposphere can alter the thermal balance of the earth's atmosphere. Outgoing terrestrial radiation which would otherwise escape to space, is trapped within the inner layer of the atmosphere, resulting in a potential warming and the greenhouse effect. It is estimated that at present greenhouse gases other than carbon dioxide, contribute about 50% to the greenhouse effect. However, in the future, the contribution made by gases other than CO{sub 2} will be become greater. Greenhouse gases arise from a wide range of sources and their escalating increase is largely related to an increase in the world's population, and the standard of living of many areas as well as changes in lifestyle. The effect of increasing man-made greenhouse gases in the troposphere is unknown, but it is proposed that it may increase temperature and may modify climate, agricultural response and land use. The facts and uncertainties relating to potential greenhouse warming are examined. Man-generated emissions are quantified and their source identified. Coal's contribution worldwide is examined in detail and is shown to be small, being about 10% of man-made greenhouse gases. Strategies for minimising emissions, having maximum potential for reduction, with minimum impact on man are suggested. 16 refs., 1 fig., 3 tabs.

Highlights: • Contribution in the control of the greenhouse microclimate for pepper cultivation. • The energy storing in the ground and in the water ensure the greenhouse heating. • The circulation of the cold water in the exchangers ensures the greenhouse cooling. • The system makes the greenhouse appropriate for the pepper cultivation whole year. - Abstract: In this papper, a thermal model is developed to investigate the possibility to use the ground thermal energy for the greenhouse heating or cooling. A control system of the ground heat storing is integrated in a chapel greenhouse located in the premises of the Technology and Research Energy Center, Tunis, Tunisia. Polypropylene capillary heat exchangers, suspended in the air and buried into the ground of the greenhouse, are used to store or destore solar energy excess. During the day, the air-suspended exchangers recuperate the solar energy in excess. This recuperated energy is then stored into the ground through the buried exchangers. At night the stored thermal energy is brought back by the suspended exchangers to heat the greenhouse air. The purpose of this study is to contribute in the greenhouse microclimate control. In order to maintain the greenhouse air temperature at 20 °C, suitable for a defined agriculture, the solar energy and the cold water are respectively used for heating and cooling the greenhouse inside air. The design and construction of a chapel greenhouse equipped with the control system is carried out. The studied system is used, at the same time for; heating, cooling the greenhouse air and storing the solar energy in excess. Experiments were conducted during the years 2012–2013, to evaluate the effectiveness of the control system achieved. The measured values of the greenhouse air temperatures with and without the control system are discussed

The South African Experience of Conservation and Social Forestry Outreach Nurseries

Science.gov (United States)

Botha, Jenny; Witkowski, Ed T. F.; Cock, Jacklyn

2006-11-01

Outreach nurseries are favored conservation and social forestry tools globally, but, as with many integrated conservation and development programs (ICDPs), they do not always produce anticipated results. A synopsis of the experience of South African practitioners is provided in this study of 65 outreach nurseries. South African outreach nurseries frequently include financial objectives, creating additional challenges in simultaneously attaining conservation and socioeconomic goals. Progress was hindered by biophysical problems (e.g., lack of water, poor soils, etc.) as well as the harsh socioeconomic conditions facing most communities in which nurseries had been established. Attaining financial viability was challenging. Business management skills were often restricted, and few viability studies included adequate market research. Costs to community participants were usually high, and benefits were limited. Conservation objectives were frequently lost in the struggle to attain financial viability. The management of social processes also proved challenging. Although small scale and relatively straightforward compared with many ICDPs, nurseries usually require substantial institutional support, including a range of technical, business, and development services. Project time frames need to be reconsidered, as practitioners estimate that it takes 5-10 years for nurseries to start meeting objectives, and donors and implementing agencies often operate on 2-3-year project cycles. Detailed viability studies are essential, incorporating a social probe and an assessment of potential impacts of projects on community participants. Progress needs to be continuously evaluated to enable institutions and community participants to adapt to changing conditions as well as ensure that the spectrum of objectives are being achieved.

Nuclear power and the greenhouse effect

International Nuclear Information System (INIS)

1989-01-01

Carbon dioxide from fossil fuel combustion accounts for about 40% of the global warming due to the 'greenhouse effect'. Thus national energy policies of the fuels used to generate electricity can have a significant effect on the levels of gas emissions which contribute to the 'greenhouse effect'. The more efficient use of energy is the first way of controlling the increase in gas emissions. The use of natural gas instead of coal or oil would also be beneficial but the reserves of natural gas are limited. The use of nuclear-generated electricity has already reduced the level of global warming by 3% but could have a greater effect in the future. Ways in which the government could reduce 'greenhouse' gas emissions are listed. These include the more extensive use of nuclear power for generating electricity not only for domestic but industrial uses. (U.K.)

Limitation of peak fitting and peak shape methods for determination of activation energy of thermoluminescence glow peaks

CERN Document Server

Sunta, C M; Piters, T M; Watanabe, S

1999-01-01

This paper shows the limitation of general order peak fitting and peak shape methods for determining the activation energy of the thermoluminescence glow peaks in the cases in which retrapping probability is much higher than the recombination probability and the traps are filled up to near saturation level. Right values can be obtained when the trap occupancy is reduced by using small doses or by post-irradiation partial bleaching. This limitation in the application of these methods has not been indicated earlier. In view of the unknown nature of kinetics in the experimental samples, it is recommended that these methods of activation energy determination should be applied only at doses well below the saturation dose.

Fostering Environmental Literacy For A Changing Earth: Interactive and Participatory Outreach Programs at Biosphere 2

Pavao-Zuckerman, M.; Huxman, T.; Morehouse, B.

2008-12-01

Earth system and ecological sustainability problems are complex outcomes of biological, physical, social, and economic interactions. A common goal of outreach and education programs is to foster a scientifically literate community that possesses the knowledge to contribute to environmental policies and decision making. Uncertainty and variability that is both inherent in Earth system and ecological sciences can confound such goals of improved ecological literacy. Public programs provide an opportunity to engage lay-persons in the scientific method, allowing them to experience science in action and confront these uncertainties face-on. We begin with a definition of scientific literacy that expands its conceptualization of science beyond just a collection of facts and concepts to one that views science as a process to aid understanding of natural phenomena. A process-based scientific literacy allows the public, teachers, and students to assimilate new information, evaluate climate research, and to ultimately make decisions that are informed by science. The Biosphere 2 facility (B2) is uniquely suited for such outreach programs because it allows linking Earth system and ecological science research activities in a large scale controlled environment setting with outreach and education opportunities. A primary outreach goal is to demonstrate science in action to an audience that ranges from K-12 groups to retired citizens. Here we discuss approaches to outreach programs that focus on soil-water-atmosphere-plant interactions and their roles in the impacts and causes of global environmental change. We describe a suite of programs designed to vary the amount of participation a visitor has with the science process (from passive learning to data collection to helping design experiments) to test the hypothesis that active learning fosters increased scientific literacy and the creation of science advocates. We argue that a revised framing of the scientific method with a more

2016-06-01

Full Text Available Greenhouse detection using remote sensing technologies is an important research area for yield estimation, sustainable development, urban and rural planning and management. An approach was developed in this study for the detection and delineation of greenhouse areas from high resolution satellite imagery. Initially, the candidate greenhouse patches were detected using supervised classification techniques. For this purpose, Maximum Likelihood (ML, Random Forest (RF, and Support Vector Machines (SVM classification techniques were applied and compared. Then, sieve filter and morphological operations were performed for improving the classification results. Finally, the obtained candidate plastic and glass greenhouse areas were delineated using boundary tracing and Douglas Peucker line simplification algorithms. The proposed approach was implemented in the Kumluca district of Antalya, Turkey utilizing pan-sharpened WorldView-2 satellite imageries. Kumluca is the prominent district of Antalya with greenhouse cultivation and includes both plastic and glass greenhouses intensively. When the greenhouse classification results were analysed, it can be stated that the SVM classification provides most accurate results and RF classification follows this. The SVM classification overall accuracy was obtained as 90.28%. When the greenhouse boundary delineation results were considered, the plastic greenhouses were delineated with 92.11% accuracy, while glass greenhouses were delineated with 80.67% accuracy. The obtained results indicate that, generally plastic and glass greenhouses can be detected and delineated successfully from WorldView-2 satellite imagery.

With the advances in high bandwidth communications and the proliferation of social media tools, education & outreach activities have become commonplace on ocean-bound research cruises. In parallel, advances in underwater robotics & other data collecting platforms, have made it possible to collect copious amounts of oceanographic data. This data then typically undergoes laborious, manual processing to transform it into quantitative information, which normally occurs post cruise resulting in significant lags between collecting data and using it for scientific discovery. This presentation discusses how appropriately designed software systems, can be used to fulfill multiple objectives and attempt to leverage public engagement in order to compliment science goals. We will present two software platforms: the first is a web browser based tool that was developed for real-time tracking of multiple underwater robots and ships. It was designed to allow anyone on board to view or control it on any device with a web browser. It opens up the possibility of remote teleoperation & engagement and was easily adapted to enable live streaming over the internet for public outreach. While the tracking system provided context and engaged people in real-time, it also directed interested participants to Squidle, another online system. Developed for scientists, Squidle supports data management, exploration & analysis and enables direct access to survey data reducing the lag in data processing. It provides a user-friendly streamlined interface that integrates advanced data management & online annotation tools. This system was adapted to provide a simplified user interface, tutorial instructions and a gamified ranking system to encourage "citizen science" participation. These examples show that through a flexible design approach, it is possible to leverage the development effort of creating science tools to facilitate outreach goals, opening up the possibility for acquiring large volumes of

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

Negotiations towards a global framework convention on climate change are hampered by the range of greenhouse gases, sources and sinks. The US government promotes a comprehensive approach to climate change which provides flexibility but faces obstacles arising from the different characteristics of the sources and sinks involved, and uncertainties in attempting to estimate and compare the radiative impacts of different gases. Relying on approximations to enable a comprehensive approach is unrealistic for two reasons: monitoring and revision. The comprehensive approach is a worthwhile goal but is not yet fully practicable. Two lists are suggested - a quantified list for CFCs and CO{sub 2} and a transition list. Frequent renegotiation would be necessary. With this approach an overall goal for controlling the magnitude and rate of change in greenhouse forcing is possible. 12 refs., 1 fig.

Accounting for variation in designing greenhouse experiments with special reference to greenhouses containing plants on conveyor systems

Science.gov (United States)

2013-01-01

Background There are a number of unresolved issues in the design of experiments in greenhouses. They include whether statistical designs should be used and, if so, which designs should be used. Also, are there thigmomorphogenic or other effects arising from the movement of plants on conveyor belts within a greenhouse? A two-phase, single-line wheat experiment involving four tactics was conducted in a conventional greenhouse and a fully-automated phenotyping greenhouse (Smarthouse) to investigate these issues. Results and discussion Analyses of our experiment show that there was a small east–west trend in total area of the plants in the Smarthouse. Analyses of the data from three multiline experiments reveal a large north–south trend. In the single-line experiment, there was no evidence of differences between trios of lanes, nor of movement effects. Swapping plant positions during the trial was found to decrease the east–west trend, but at the cost of increased error variance. The movement of plants in a north–south direction, through a shaded area for an equal amount of time, nullified the north–south trend. An investigation of alternative experimental designs for equally-replicated experiments revealed that generally designs with smaller blocks performed best, but that (nearly) trend-free designs can be effective when blocks are larger. Conclusions To account for variation in microclimate in a greenhouse, using statistical design and analysis is better than rearranging the position of plants during the experiment. For the relocation of plants to be successful requires that plants spend an equal amount of time in each microclimate, preferably during comparable growth stages. Even then, there is no evidence that this will be any more precise than statistical design and analysis of the experiment, and the risk is that it will not be successful at all. As for statistical design and analysis, it is best to use either (i) smaller blocks, (ii) (nearly) trend

Does the Swedish consumer's choice of food influence greenhouse gas emissions?

2004-01-01

Consumer's choice of food can influence the environment. In Sweden, in common with many other countries, consumers need to be given information so they can make environmentally informed shopping choices. However, what is the most advantageous dietary choice to lower greenhouse emissions? This study investigates the greenhouse gas emissions associated with food production for food consumed in Sweden annually. Specifically, this study compares greenhouse gas emissions associated with a nutritionally and environmentally sustainable diet with the average consumption of food in Sweden 1999. The study concludes that the change in energy use and greenhouse gas emission associated with this change of diet is negligible. Lowering greenhouse gas emissions by changing food production processes results in more profound changes than teaching consumers to make environmentally correct choices. There is a basic need for a reduction or a replacement of the use of fossil fuels to produce and distribute our food in order to reach any significant reduction in the emission of greenhouse gases. Swedish agricultural policy does not provide ways to reduce greenhouse gas emissions. In Sweden therefore there is an immediate need to design policy instruments with the primary aim of reducing the greenhouse effect

Global levels of the ''Greenhouse'' gases - carbon dioxide, the chlorofluorocarbons (CFCs), methane, nitrous oxide and tropospheric ozone are increasing as a result of man's activities. This increase is widely expected to bring about a rise in global temperature with concomitant environmental impacts. Global warming has been observed over the last century, and the last decade has seen seven of the warmest years on record. There has also been increased variability in the weather (an expected consequence of global warming). However, these possible manifestations of the Greenhouse Effect are within natural variations and proof must await more definitive indications. A brief outline of current views on the Greenhouse Effect is given. This report addresses the energy sector using CO 2 emissions as a measure of its ''Greenhouse'' contribution. This approach understates the energy sector contribution. However, the difference is within the error band. It seems likely that the warming effect of non-energy related emissions will remain the same and there will be more pressure to reduce the emissions from the energy sector. To assess policy options the pattern of future energy demand is estimated. Two scenarios have been adopted to provide alternative frameworks. Both assume low energy growth projections based on increased energy efficiency. The role of nuclear power in reducing carbon dioxide emissions is considered. (author)

Full Text Available The Objective of research to acknowledge the hypothesis: outreach islamic microfinance for the poor household of agricultural sector at rural Bogor West Java. The majority of the poor community in Indonesia stay at rural areas. Lack of access credit/financing generally seen as one of the main reasons why many people remain poor. Credit/financing as a powerful instrument to help poor people break out of the vicious cycle because it has the potential to improve income and savings, consequently, enhance capital accumulation, and reinforce high incomes, but providing credit to the poor of agricultural sector in many cases is a very costly activity. Bank isn’t interest to serve it. Hopefully, islamic microfinance institutions reaches to more the poor of agricultural sector. The average loan is the most commonly used to measure the degree of microfinance institutions (MFIs outreach to poor customer segments, but it is very simple. Using the CGAP (Consultative Group to assist the poorest method, the poverty multidimension of islamic microfinance outreach was measured. The result of study showed that islamic MFIs didn’t reach the poor household of agricultural sector at rural Bogor West Java.

The Society of Physics Students chapter at Indiana Wesleyan University is unusual in that it has no physics major, only physics minors. Yet while just over a year old, IWU-SPS has been active in performing physics outreach to middle school and high school students, and the rural community of Grant County. Our year-old SPS chapter consists of majors from Chemistry, Nursing, Biology, Exercise Science, Computer Science, Psychology, Pastoral Studies, and Science Education, who share a common interest in physics and service to the community. IWU currently has a physics minor and is currently working to build a physics major program. Despite the intrinsic challenges, our multi-disciplinary group has been successful at using physics demonstration equipment and hands-on activities and their universal appeal to raise the interest in physics in Grant County. We report our experience, challenges, and successes with physics outreach. We describe in detail our two-pronged approach: raising the level of physics appreciation among the IWU student community and among pre-college students in a rural community of Indiana.

Abellan, Carlos; Tura, Jordi; Garcia, Marta; Beduini, Federica; Hirschmann, Alina; Pruneri, Valerio; Acin, Antonio; Marti, Maria; Mitchell, Morgan

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.

Assessment of the impact of the greenhouse gas emission and sink scenarios in Finland on radiative forcing and greenhouse effect

Energy Technology Data Exchange (ETDEWEB)

Savolainen, I; Sinisalo, J; Pipatti, R [Technical Research Centre of Finland, Espoo (Finland)

1997-12-31

The objective of this work is to study greenhouse gas emissions and sinks and their greenhouse impact as a function of time. The greenhouse impact is expressed in terms of global average radiative forcing, which measures the perturbation in the Earth`s radiation budget. Radiative forcing is calculated on the basis of the concentration changes of the greenhouse gases and the radiation absorption properties of the gases. It takes into account the relatively slow changes in the concentrations due to natural removal and transformation processes and also allows a comparison of the impact of various greenhouse gases and their possible control options as a function of time. In addition to the applications mentioned above, the anthropogenic greenhouse gas emission histories of Nordic countries have been estimated, and the radiative forcing caused by them has been calculated with REFUGE. The dynamic impact of aerosol emissions both from the global point of view and in the context of different energy sources (coal, oil and natural gas) have also been studied. In some instances the caused radiative forcing has been examined on a per capita basis. The radiative forcing calculations contain considerable uncertainty due to inaccurately known factors at several stages of the calculation (emission estimation, concentration calculation and radiative forcing calculation). The total uncertainty of the results is typically on the order of +- 40 %, when absolute values are used. If the results are used in a relative way, e.g. to compare the impacts of different scenarios, the final uncertainty is considerably less (typically + 10 %), due to correlations in almost all stages of the calculation process

Greenhouse effect: doubts and unknowns

International Nuclear Information System (INIS)

Tabarelli, D.

1992-01-01

There are few doubts today in the scientific world that atmospheric carbon dioxide traps in heat and therefore contributes to global warming; however, it is yet uncertain as to whether the presence of this gas in the upper atmosphere is the only cause of the greenhouse effect, and the scientific theories defining the effect and its causes present a few obvious and significant gaps. This paper cites the fact that most greenhouse effect models only marginally, if at all, consider the mechanisms governing the formation and absorption of carbon dioxide by the earth's oceans; yet oceanic CO 2 concentration levels are about 60 times greater than those found in the atmosphere, and they depend on complex interactions, in seawater, among such factors as currents, carbon oxygenation, and vegetative activity. Another area of weakness in greenhouse effect modelling stems from the complexity and uncertainty introduced by the fact that, in addition to trapping heat, clouds reflect it, thus giving rise to an opposite cooling effect. In addition, it is pointed out that the current models are limited to predicting global and not regional or local effects

The rate at which the global average surface temperature is increasing has slowed down since the end of the last century. This study investigates whether this warming hiatus results from a change in the well-known greenhouse effect. Using long-term, reliable, and consistent observational data from the Earth?s surface and the top of the atmosphere (TOA), two monthly gridded atmospheric and surface greenhouse effect parameters (G a and G s) are estimated to represent the radiative warming effec...

Effect of greenhouse micro-climate on the selected summer vegetables

2003-01-01

The study deals with creating suitable environment for the germination and subsequent growth of plants in the greenhouse of size 7 m x 3 m x 2 m for raising early summer vegetable nursery. It was observed that the average air temperature inside the greenhouse was 10–12°C higher than the ambient air temperature. Inside average soil temperature was also 5–7°C higher than the corresponding temperature outside the greenhouse. Greenhouse night micro-climate was modified by covering its roof with a polyester sheet to cut down the effect of night sky radiation thereby raising the inside minimum temperature. The effect of elevated temperature was monitored on the germination and subsequent growth of “muskmelon” seedlings up to two true leaf stage. It was observed that the germination of seeds, sown inside the greenhouse occurred one week earlier as compared to the seeds sown in the open field. The rate of growth of the seedlings inside the greenhouse took only three weeks to attain two-leaf stage, whereas seedlings sown in the open field took five weeks to reach up to two-leaf stage. Thus, there was a clear saving of 15 days in raising the nursery under the greenhouse. (author)

Peak tree: a new tool for multiscale hierarchical representation and peak detection of mass spectrometry data.

Peak detection is one of the most important steps in mass spectrometry (MS) analysis. However, the detection result is greatly affected by severe spectrum variations. Unfortunately, most current peak detection methods are neither flexible enough to revise false detection results nor robust enough to resist spectrum variations. To improve flexibility, we introduce peak tree to represent the peak information in MS spectra. Each tree node is a peak judgment on a range of scales, and each tree decomposition, as a set of nodes, is a candidate peak detection result. To improve robustness, we combine peak detection and common peak alignment into a closed-loop framework, which finds the optimal decomposition via both peak intensity and common peak information. The common peak information is derived and loopily refined from the density clustering of the latest peak detection result. Finally, we present an improved ant colony optimization biomarker selection method to build a whole MS analysis system. Experiment shows that our peak detection method can better resist spectrum variations and provide higher sensitivity and lower false detection rates than conventional methods. The benefits from our peak-tree-based system for MS disease analysis are also proved on real SELDI data.

Men who use the Internet to seek sex with other men (MISM) are increasingly using the Internet to find sexual health information and to seek sexual partners, with some research suggesting HIV transmission is associated with sexual partnering online. Aiming to "meet men where they are at," some AIDS service organizations (ASOs) deliver online outreach services via sociosexual Internet sites and mobile apps. To investigate MISM's experiences and self-perceived impacts of online outreach. From December 2013 to January 2014, MISM aged 16 years or older were recruited from Internet sites, mobile apps, and ASOs across Ontario to complete a 15-minute anonymous online questionnaire regarding their experience of online outreach. Demographic factors associated with encountering online outreach were assessed using backward-stepwise multivariable logistic regression (P<.05 was considered significant). Of 1830 MISM who completed the survey, 8.25% (151/1830) reported direct experience with online outreach services. Encountering online outreach was more likely for Aboriginal versus white MISM, MISM from Toronto compared with MISM from either Eastern or Southwestern Ontario, and MISM receiving any social assistance. MISM who experienced online outreach felt the service provider was friendly (130/141, 92.2%), easy to understand (122/140, 87.1%), helpful (115/139, 82.7%), prompt (107/143, 74.8%), and knowledgeable (92/134, 68.7%); half reported they received a useful referral (49/98, 50%). Few MISM felt the interaction was annoying (13/141, 9.2%) or confusing (18/142, 12.7%). As a result of their last online outreach encounter, MISM reported the following: better understanding of (88/147, 59.9%) and comfort with (75/147, 51.0%) their level of sexual risk; increased knowledge (71/147, 48.3%); and feeling less anxious (51/147, 34.7%), better connected (46/147, 31.3%), and more empowered (40/147, 27.2%). Behaviorally, they reported using condoms more frequently (48/147, 32.7%) and

A general presentation of climatic changes due to greenhouse effect with their consequences is analysed. After a schematic description of this effect a simplified atmospheric model (box model) is proposed. This model integrates the main feedback effects and quantifies them. The effects of astronomic and atmospheric factors on climatic changes are analyzed and compared with classical paleoclimatic results. This study shows the need of good global modelization to evaluate long term quantification of climatic greenhouse effects according to the main time lag of the several biospheric boxes. An overview of biologic and agronomic consequences is given to promote new research subjects and to orientate protecting and conservative biospheric actions [fr

There is evidence that Cognitive Stimulation Therapy and maintenance Cognitive Stimulation Therapy are effective in mild to moderate dementia. There is, however, little evidence available for its implementation in practice and the impact of outreach support on the sustainability of the programme. Two hundred and forty-one staff members were randomised from 63 dementia care settings between outreach support including an online forum, email, and telephone support, compared to usual Cognitive Stimulation Therapy control group. The primary outcome was average number of attendees to the Cognitive Stimulation Therapy and maintenance Cognitive Stimulation Therapy programmes. There was no difference in average number of attendees between the intervention and usual Cognitive Stimulation Therapy control groups for the Cognitive Stimulation Therapy (p = 0.82) or the maintenance Cognitive Stimulation Therapy programme (p = 0.97). Outreach support does not affect the average number of people with dementia attending the Cognitive Stimulation Therapy or maintenance Cognitive Stimulation Therapy programme. Irrespective of outreach support, the programmes remain widely implemented and yield perceived benefits for people with dementia. Copyright © 2017 John Wiley & Sons, Ltd.

In these last years, a great deal of interest has been devoted to double-skin facades due to the advantages claimed by this technology (in terms of energy saving in the cold season, high-tech image, protection from external noise and wind loads). One of the great characteristics of the double-skin facade is the greenhouse effect. We identify the factors that influence the greenhouse effect. The identified parameters are solar radiation level, orientation and shading devices use, opaque wall/window proportion of the interior facade, wind speed, colour of shading devices and of interior facade, depth of the cavity of the double-skin, glazing type in the interior facade and openings in the double-skin. We analyze the impact of these parameters on the mean air temperature evolution in the cavity. After that analyse, the article answers the question: is greenhouse effect favourable? The answer is moderate according to the double-skin orientation. (author)

The Greenhouse Effect and Climate Feedbacks

Science.gov (United States)

Covey, C.; Haberle, R. M.; McKay, C. P.; Titov, D. V.

This chapter reviews the theory of the greenhouse effect and climate feedback. It also compares the theory with observations, using examples taken from all four known terrestrial worlds with substantial atmospheres: Venus, Earth, Mars, and Titan. The greenhouse effect traps infrared radiation in the atmosphere, thereby increasing surface temperature. It is one of many factors that affect a world's climate. (Others include solar luminosity and the atmospheric scattering and absorption of solar radiation.) A change in these factors — defined as climate forcing — may change the climate in a way that brings other processes — defined as feedbacks — into play. For example, when Earth's atmospheric carbon dioxide increases, warming the surface, the water vapor content of the atmosphere increases. This is a positive feedback on global warming because water vapor is itself a potent greenhouse gas. Many positive and negative feedback processes are significant in determining Earth's climate, and probably the climates of our terrestrial neighbors.

Analysis of the internal shading in a photovoltaic greenhouse tunnel

Directory of Open Access Journals (Sweden)

Alvaro Marucci

2017-09-01

Full Text Available In recent years, the increasing interest in energy production from renewable energy sources has led to photovoltaic elements being placed on greenhouse coverings. The shading of crops by these elements can, however, cause problems regarding the normal course of agricultural activity. All studies thus far on the application of photovoltaic (PV panels as a greenhouse covering material have focused on flat roof structures. Tunnel greenhouses, due to their curved shape, do not lend themselves easily to accommodating PV panels on even part of the cover. In this study, we analysed the shading variation inside a tunnel greenhouse that was produced by applying flexible and transparent PV panels in a checkerboard arrangement. The transparent flexible PV panels are manufactured using monocrystalline silicon cells, with an efficiency of 18%, incorporated into polymers with high resistance. The PV panel dimensions are 1.116×0.165 m. The simulation software Autodesk® Autocad2010® was used for this study. The variation and distribution of the shading percentage of PV panels were analysed in relation to the surface area affected by the photovoltaic roof, the total area of the greenhouse and the section of the greenhouse. In particular, we studied the variations in the percentage of shading and the size of the shaded area on the twenty-first day of each month of the year. The results show some regularity in the shading percentage, mainly due to the curvilinear shape of the section of the greenhouse. From mid-March to mid- September, the shading in the middle of the day is almost always inside the greenhouse. In the other months of the year, it is partly inside and partly outside the tunnel greenhouse. With the photovoltaic arrangement adopted, the percentage of shading during the year never exceeds 40%.

Astrobiology outreach and the nature of science: the role of creativity.

2012-12-01

There is concern in many developed countries that school students are turning away from science. However, students may be choosing not to study science and dismissing the possibility of a scientific career because, in the junior secondary years, they gain a false view of science and the work of scientists. There is a disparity between science as it is portrayed at school and science as it is practiced. This paper describes a study to explore whether engaging in science through astrobiology outreach activities may improve students' understanding of the nature and processes of science, and how this may influence their interest in a career in science. The results suggest that the students attending these Mars research-related outreach activities are more interested in science than the average student but are lacking in understanding of aspects of the nature of science. A significant difference was detected between pre- and posttest understandings of some concepts of the nature of science.

Stakeholder involvement and public outreach at two Department of Energy sites

Outreach efforts at two U.S. Department of Energy sites (i.e., the Hanford Site in southeastern Washington and Pantex Plant in the Texas panhandle) have involved a broad spectrum of communications media, including technical presentations and articles, information brochures and fact sheets, video productions; interactive exhibits; presentations at civic and other public meetings; and proactive interactions with the news media, regulators and concerned citizens. In addition, representatives of local communities operate offsite environmental monitoring stations and Native Americans are involved in studying cultural resources, fisheries, and other issues at Hanford, and a program to obtain environmental samples from neighbors property is underway at Pantex. All major environmental programs (e.g., the reconstruction of past radiological doses to offsite human populations at Hanford) are conducted with open public participation, the Pantex Plant has opened an Information office in Amarillo, Texas, and both sites now have Citizen's Advisory Boards. This presentation describes Hanford and Pantex public outreach and involvement efforts, our successes and failures, and the lessons learned

MASE: a Great Opportunity for Outreach to the Rural Communities in Mexico

The MesoAmerican Subduction Experiment (MASE) deployed 100 seismic stations across Mexico between Acapulco and Tampico, passing through Mexico City at the midpoint. Deploying the instruments at a secure site was an important issue, schools are nearly ideal in this respect. Consequently, 54 MASE stations are situated in schools that range from the K-12 through the University level. This presented a golden opportunity to outreach to rural communities, since the students come from small towns around the school and can spread the word to their home towns. Given the constant earthquake activity in Mexico and its history of destruction, the societal responsibility of UNAM, it is crucial to educate people in understanding a phenomenon that affects their daily lives and to prepare them to deal with it. One challenge in achieving this commitment is the diversity of level of knowledge of earthquakes. We address this by giving out different examples and utilizing didactic material adequate to the level, together with a series of talks, posters, handouts, etc., that cover topics from the Earth structure through the purpose of MASE. The program is being carried out by undergraduate students from the School of Engineering at UNAM, the program also provides an invaluable outreach experience to them. From this experience, we conclude that large-scale experiments like this should be accompanied by a committed outreach program given the large number of people that would be touched by it.

The plan is intended to better manage the impacts of urban development related to GHG and air quality, while also achieving community objectives related to affordable housing, transportation management, job creation and economic development. The report reviewed the local emissions inventory in addition to various programs, plans, policies and by-laws relating to energy management. Potential policies and programs were identified to achieve GHG emissions reductions in accordance with the PCPP. A plan for emissions reductions was also presented. A situation analysis was presented with details of population, transportation, residential and commercial building and industry. Solid waste management and transportation plans were outlined. A GHG emissions profile and forecast was presented. An outline of a GHG management framework included information on initiatives in the city as well as details of public consultation feedback. A program implementation plan includes forecasts of the program's impact, as well as details of program delivery and a performance measurement framework. Proposed initiatives in the plan included new building guidelines; fuel switching for light and heavy duty vehicles; driver training and enhanced vehicle maintenance programs; and, an environmental procurement policy. Community programs include residential and commercial building retrofits; land use planning; support for community energy systems; green building design guidelines; transportation demand management; and, public engagement and outreach programs. 21 tabs., 9 figs

A study of indoor radon in greenhouses in Mexico City, Mexico

Guillermo Espinosa; Allan Chavarria; Jose-Ignacio Golzarri

2013-01-01

Enclosed spaces in contact with soil, the main source of radon, like greenhouses have potentially high radon ( 222 Rn) concentrations. Greenhouses are frequented by visitors and also are workplaces. The study of radon concentrations in greenhouses is, thus, a relevant concern for public health and environmental radiation authorities. For this study, the radon concentrations in 12 greenhouses in different locations within Mexico City were measured using nuclear track methodology. The detectors used for the study consisted of the well-known closed-end cup device, with CR-39 Lantrack R as detector material. The measurements were carried out over a period of one year, divided into four three-month sub-periods. The lowest and highest annual mean radon concentrations found in individual greenhouses were 17.0 and 45.1 Bq/m 3 , respectively. The annual mean averaged over all 12 greenhouses was 27.3 Bq/m 3 . No significant seasonal variation was observed. Using the highest annual mean radon concentration found in an individual greenhouse, and an equilibrium factor of 0.4, the effective dose from 222 Rn and its progenies was calculated to be 339.9 nSv/h. This corresponds to an annual dose rate of 679.8 μSv/y (0.057 WLM/y) for a worker spending 4 h a day, 5 days a week, 50 weeks a year, inside the greenhouse. For a visitor spending 12 h a year inside the greenhouse the annual dose is 2.469 μSv/y. The study of indoor radon concentrations in closed buildings such as greenhouses, which are both workplaces and open to visitors, is an important public health consideration. (author)

Sonic anemometry measurements to determine airflow patterns in multi-tunnel greenhouse

Energy Technology Data Exchange (ETDEWEB)

Lopez, A.; Valera, D. L.; Molina-aiz, F. D.; Pena, A.

2012-11-01

The present work describes a methodology for studying natural ventilation in Mediterranean greenhouses using sonic anemometry. The experimental work took place in the three-span greenhouse located at the agricultural research farm belonging to the University of Almeria. This methodology has allowed us to obtain patterns of natural ventilation of the experimental greenhouse under the most common wind regimes for this region. It has also enabled us to describe how the wind and thermal effects interact in the natural ventilation of the greenhouse, as well as to detect deficiencies in the ventilation of the greenhouse, caused by the barrier effect of the adjacent greenhouse (imply a mean reduction in air velocity close to the greenhouse when facing windward of 98% for u, 63% for u, and more importantly 88% for ux, the component of air velocity that is perpendicular to the side vent). Their knowledge allows us to improve the current control algorithms that manage the movement of the vents. In this work we make a series of proposals that could substantially improve the natural ventilation of the experimental greenhouse. For instance, install vents equipped with ailerons which guide the air inside, or with vents in which the screen is not placed directly over the side surface of the greenhouse. A different proposal is to prolong the opening of the side vents down to the soil, thus fomenting the entrance of air at crop level. (Author) 34 refs.
